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) On November 2, 2010, MP Thrift Investments L.P. ("MP Thrift") purchased 72,307,263 shares of Common Stock of Flagstar Bancorp, Inc. (the "Issuer") and, on the same date, MP Thrift purchased 8,884,637 shares of Mandatorily Convertible Non-Cumulative Perpetual Preferred Stock, Series D ("Convertible Preferred Stock"), both in registered public offerings.
(2) MPGOP III Thrift AV-I L.P. ("MPGOP"), a Delaware limited partnership and MPGOP (Cayman) III Thrift AV-I L.P., a Cayman Islands exempted limited partnership ("MPGOP Cayman", and together with MPGOP, the "New Fund") together hold 100% of the membership interests in MP Thrift. MPGOP has a 77.05% interest in MP Thrift and MPGOP Cayman has a 22.95% interest in MP Thrift. MP (Thrift) Global Partners III LLC ("MP LLC") is a limited liability company organized under the laws of Delaware. The principal business of MP LLC is to serve as general partner of each of MPGOP, MPGOP Cayman, MP Thrift, MP (Thrift) Global Opportunities Partners (Special) III LP ("MPGOPS"), and MP (Thrift) Global Opportunities Investments III LP ("MPGOI"). MP (Thrift) Asset Management LLC ("MPAM") is a limited liability company organized under the laws of Delaware. MPAM is the managing member of MP LLC. MP (Thrift) LLC ("MPT") is a limited liability company organized under the laws of Delaware.
(3) (continued from footnote 2) MPT is the managing member of MPAM. MPGOPS is a limited partnership organized under the laws of Delaware. MPGOPS is the holder of a 100% limited partnership interest in MPGOI. MPGOI is a limited partnership organized under the laws of Delaware. MPGOI is the holder of a 1% limited partnership interest in the New Fund. Along with MPT, MPAM, MP LLC, and MPGOPS, MPGOI comprises the Associates Fund.
(4) David J. Matlin and Mark R. Patterson are each a 50% managing member of MPT. David J. Matlin's principal occupation is acting as Chief Executive Officer of MatlinPatterson Global Advisers LLC ("Matlin Advisers") and Mark R. Patterson's principal occupation is acting as Chairman of Matlin Advisers. Matlin Advisers is a limited liability company organized under the laws of Delaware. The principal business of Matlin Advisers is to serve as investment adviser to the various funds. Matlin Advisers also serves as investment adviser to the New Fund. Gregory Eng is a director of the Issuer. Although Gregory Eng does not have voting or investment control over shares held by MP LLC, Mr. Eng may be deemed to have an indirect pecuniary interest in such shares through his indirect interest in a limited partnership which holds an investment interest and carried interest in the various funds.
(5) Mr. Eng's exact pecuniary interest therein is not readily determinable because it is subject to several variables, including without limitation, the internal rates of return of the funds overall and with respect to their indirect investment in the Issuer. He disclaims beneficial ownership of any of the reported securities except to the extent of his pecuniary interest therein.
