Explanation of responses

F1In connection with the Issuer's registered rights offering that commenced on July 22, 2014 (the "Rights Offering"), the Reporting Persons identified in footnote (2) irrevocably exercised their basic subscription rights to purchase up to their pro rata portion of the total number of shares of Issuer common stock to be issued in the Rights Offering at a price of $16.00 per share. On August 13, 2014, the subscription period ended and on August 14, 2014 the Issuer announced that the Rights Offering was fully subscribed through the exercise of basic subscription and oversubscription rights. As a result of the Rights Offering being fully subscribed, the aggregate number of shares of Issuer common stock subscribed for and purchased by the Reporting Persons identified in footnote (2) became fixed at 1,495,400 shares.
F2Shares are held (and subscription rights were held) directly by Whitebox Asymmetric Partners, L.P. ("WAP"), Whitebox Multi-Strategy Partners, L.P. ("WMSP"), Whitebox Credit Arbitrage Partners, L.P. ("WCRAP"), Whitebox Concentrated Convertible Arbitrage Partners, L.P. ("WCCAP"), Pandora Select Partners, L.P. ("PSP"), Whitebox Special Opportunities Fund, L.P. - Series O ("WSOF"), Whitebox Institutional Partners, L.P. ("WIP") and Whitebox Tactical Opportunities Fund ("WTOF"), which is a series of Whitebox Mutual Funds, a Delaware investment trust.
F3Indirect beneficial ownership is attributable to Whitebox Advisors LLC ("WA") (i) as managing member of Whitebox Asymmetric Advisors, LLC ("WAA"), Whitebox Multi-Strategy Advisors, LLC ("WMSA"), Whitebox Credit Arbitrage Advisors, LLC ("WCRAA"), Whitebox Concentrated Convertible Arbitrage Advisors, LLC ("WCCAA"), Pandora Select Advisors, LLC ("PSA"), and Whitebox Special Opportunities Advisors, LLC ("WSOA"), which act as general partners to WAP, WMSP, WCRAP, WCCAP, PSP and WSOF, respectively; (ii) as general partner to WIP and (iii) as investment adviser to WTOF.
F4Under the terms of the Rights Offering, each share of Issuer common stock outstanding on July 21, 2014 received one transferable subscription right to purchase 0.21 shares of Issuer common stock at a subscription price equal to $16.00 per whole share (subject to rounding down to avoid the issuance of fractional shares).
F5Warrants that may be exercised to acquire shares of the Issuer's common stock are held directly by the Reporting Persons identified in footnote (6), and were originally acquired by such Reporting Persons on August 31, 2012 and reported in a Form 3 filed on September 12, 2012. The number of warrant shares currently disclosed reflects the effect of anti-dilution adjustments since that time in connection with the Issuer's 1 for 10 reverse stock split and issuances of additional common stock by the Issuer in settlement of previously unresolved claims under the Issuer's Chapter 11 Plan of Reorganization.
F6Warrants are held directly by WAP, WMSP, WCRAP, WCCAP and PSP.
F7This amendment has been filed solely to correct the total number of Issuer common shares beneficical owned as reported in column 5 of Table I and to correct the number of warrants beneficially owned as reported in columns 7 and 9 of Table II, in each case to reflect revised anti-dilution adjustments in connection with the Issuers's 1 for 10 reverse stock split.
