* 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) Flat Ridge Investments LLC ("Flat Ridge") directly and beneficially owns all of the reported Common Stock and Sponsors' Warrants (as defined below). David A. Minella, the Managing Member of Flat Ridge, disclaims beneficial ownership of the securities except to the extent of his pecuniary interest therein and this report shall not be deemed an admission that David A. Minella is the beneficial owner of the securities for purposes of Section 16 or for any other purpose.
(2) On October, 16, 2007, as a result of a 5-for-3 stock split declared by the Issuer's board of directors, an additional 1,545,312 shares of Common Stock were issued to Flat Ridge, bringing its total ownership as of October 16, 2007 to 3,863,281 shares of Common Stock.
(3) Sponsors' warrants (the "Sponsors' Warrants") are identical to the warrants offered by Prospect Acquisition Corp. (the "Issuer") in its initial public offering (the "IPO"), except for those differences set forth in the final prospectus relating to the IPO (the "Prospectus"). In addition, the Sponsors' Warrants generally are not transferable, assignable or saleable until 30 days after the completion of the Issuer's initial business combination, except to certain permitted transferees, and shall expire worthless if the Issuer does not complete an initial business combination within 24 months after the date of the Prospectus.
(4) The Sponsors' Warrants become exercisable on the later of the completion of the Issuer's initial business combination and 15 months from the date of the Prospectus, provided that the Sponsors' Warrants can not be exercised while subject to the transfer restrictions described above.
(5) The Sponsors' Warrants expire five years from the date of the Prospectus or earlier upon redemption or liquidation of the Issuer.
