(1) IMPORTANT NOTE: THE SECURITIES SET FORTH IN THIS REPORT ARE DIRECTLY BENEFICIALLY OWNED BY HARBINGER CAPITAL PARTNERS MASTER FUND I, LTD. AND/OR HARBINGER CAPITAL PARTNERS SPECIAL SITUATIONS FUND, L.P. (COLLECTIVELY, THE "FUNDS"). ALL OTHER ENTITIES AND PERSONS ARE INCLUDED WITHIN THIS REPORT DUE TO THEIR AFFILIATION WITH ONE OR BOTH OF THE FUNDS.
(2) These securities are owned by Harbinger Capital Partners Master Fund I, Ltd. (the "Master Fund"), which is a Reporting Person.
(3) These securities may be deemed to be indirectly beneficially owned by the following, each of whom is a Reporting Person: Harbinger Capital Partners LLC ("Harbinger LLC"), the investment manager of the Master Fund; Harbinger Holdings, LLC ("Harbinger Holdings"), the managing member of Harbinger LLC; and Philip Falcone, the managing member of Harbinger Holdings and the portfolio manager of the Master Fund.
(4) Each Reporting Person listed in Footnote 3 disclaims beneficial ownership of the reported securities except to the extent of his or its pecuniary interest therein, and this report shall not be deemed an admission that such Reporting Person is the beneficial owner of the securities for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose.
(5) These securities are owned by Harbinger Capital Partners Special Situations Fund, L.P. (the "Special Situations Fund").
(6) These securities may be deemed to be indirectly beneficially owned by the following entities or persons: Harbinger Capital Partners Special Situations GP, LLC ("HCPSS"), the general partner of the Special Situations Fund; Harbinger Holdings, the managing member of HCPSS; and Philip Falcone, the managing member of Harbinger Holdings and the portfolio manager of the Special Situations Fund.
(7) Each entity or person listed in Footnote 6 disclaims beneficial ownership of the reported securities except to the extent of his or its pecuniary interest therein, and this report shall not be deemed an admission that such entity or person is the beneficial owner of the securities for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose.
(8) The Master Fund held certain Shares of the Issuer in an account at Lehman Brothers International (Europe) ("LBIE"). On September 15, 2008, LBIE was placed into administration under United Kingdom law and four partners of PriceWaterhouseCoopers LLP were appointed as joint administrators (the "Joint Administrators"). The Joint Administrators have advised that 1,113,197 of the Shares were rehypothecated.
(9) The Master Fund believes at this time that rehypothecated shares will not be recoverable. The Joint Administrators have proposed a framework which, if approved, would entitle customers to a claim for the rehypothecated securities valued as of the close of market on September 12, 2008 which would be setoff against amounts owed by such customer to LBIE.
(10) The Master Fund in this filing has reduced the number of Shares of the Issuer held by it to the extent such Shares were held at LBIE and were rehypothecated. By making this filing, the Master Fund does not waive any arguments that it is entitled to recover such Shares and expressly reserves such arguments.
(11) These securities are owned by Harbinger Capital Partners Fund I, L.P. (the "Onshore Fund"). These securities may be deemed to be beneficially owned by Harbinger Capital Partners GP, LLC ("Harbinger Capital GP"), the general partner of the Onshore Fund, Harbinger Holdings, the managing member of Harbinger Capital GP, and Philip Falcone, the managing member of Harbinger Holdings and the portfolio manager of the Onshore Fund.
