        <footnote id="F1">This report is filed jointly by Tontine Capital Partners, L.P., a Delaware limited partnership (&quot;TCP&quot;), Tontine Capital Management, L.L.C., a Delaware limited liability company (&quot;TCM&quot;), Tontine Capital Overseas GP, L.L.C., a Delaware limited liability company (&quot;TCO&quot;), Tontine Capital Overseas Master Fund, L.P., a Cayman Islands limited partnership (&quot;TMF&quot;), Tontine Capital Overseas Master Fund II, L.P., a Cayman Islands limited partnership (&quot;TCP 2&quot;), Tontine Asset Associates, L.L.C., a Delaware limited liability company (&quot;TAA&quot;) and Jeffrey L. Gendell (&quot;Mr. Gendell&quot;).  Mr. Gendell is the managing member of: (a) TCM, the general partner of TCP; (b) TCO, the general partner of TMF; and (c) TAA, the general partner of TCP 2.</footnote>
        <footnote id="F2">Effective February 1, 2010, the filing parties reallocated ownership of Common Stock among the entities comprising the filing parties (the &quot;Reallocation&quot;).  When giving effect solely to the Reallocation, the aggregate Common Stock ownership of the filing parties after the completion of the Reallocation will be the same as the aggregate Common Stock ownership of the filing parties before the Reallocation.  In connection with the Reallocation, shares of Common Stock owned by TMF (the &quot;Transferred Shares&quot;) will be deemed to have been distributed in kind as of February 1, 2010 to certain investors holding ownership interests in TMF, with all of the Transferred Shares then being immediately contributed by such investors to TCP 2.  The number of Transferred Shares reported in this Form 4 as being contributed to TCP 2 is a preliminary estimate by the filing parties.</footnote>
        <footnote id="F3">The filing parties expect to finalize the actual number of Transferred Shares by the end of February 2010, and an amendment to this Form 4 will be filed when the number of Transferred Shares is finalized.  As of the date of this Form 4, the filing parties estimate the number of Transferred Shares to be deemed distributed in kind by TMF to be 123,799 shares of Common Stock, with all of such shares being immediately contributed to TCP 2.  However, the actual number of Transferred Shares, as ultimately determined by the filing parties, may be materially different than the estimates disclosed in this footnote.</footnote>
        <footnote id="F4">Before the consummation of the transactions discussed in Footnote No. 2 to this Form 4, Mr. Gendell, TCM, TCO, TAA and TCP 2 directly own 0 shares of Common Stock, TCP directly owns 4,221,155 shares of Common Stock and TMF directly owns 953,808 shares of Common Stock.</footnote>
        <footnote id="F5">All of the foregoing securities may be deemed to be beneficially owned by Mr. Gendell.  The foregoing securities held by TCP may be deemed to be beneficially owned by TCM.  The foregoing securities held by TMF may be deemed to be beneficially owned by TCO.  Securities held by TCP 2 may be deemed to be beneficially owned by TAA.</footnote>
        <footnote id="F6">Mr. Gendell disclaims beneficial ownership of the Issuer's securities reported herein for purposes of Section 16(a) under the Securities Exchange Act of 1934, as amended, or otherwise, except as to securities directly owned by Mr. Gendell or representing Mr. Gendell's pro rata interest in, and interest in the profits of, TCM, TCP, TCO, TMF, TCP 2 and TAA.
