Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 5(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) This statement is filed by and on behalf of each of Akanthos Capital Management, LLC ("ACM") and Akanthos Arbitrage Master Fund, L.P. ("AAMF"). ACM acts as the investment adviser and general partner to, and manages investment and trading accounts of, other persons, including AAMF. ACM may be deemed, through investment advisory contracts or otherwise, to beneficially own securities owned by other persons, including AAMF. These shares of the issuer's common stock, par value $.10 per share ("Shares") are held for the account of AAMF. Reporting persons hold approximately 8,299,091 Shares of the issuer, consisting of: (A) 1,790,000 Shares; and (B) 7,160,000 units 12.50% Convertible Guaranteed Senior Notes due 2011 (the "Notes"), convertible at $1.10 per share into 6,509,091 Shares.
(2) Reporting persons exceeded the 10% threshold due to an exchange offer (the "Exchange") made by the issuer in which AAMF participated. As per the information provided by the issuer in its Prospectus dated November 24, 2008, prior to the Exchange, on November 3, 2008, the issuer had 14,256,628 Shares outstanding. As per the information provided by the issuer in its Form 8-K dated November 24, 2008, 21,310,549 were issued in the Exchange. Therefore, we understand that the outstanding Shares of the issuer total 35,567,177.
(3) The Notes are immediately convertible into Shares. The Notes mature on January 15, 2011, unless earlier converted or repurchased.
(4) The initial conversion rate of the Notes is 909.0909 Shares per $1,000 principal amount of Notes (equal to a conversion price of approximately $1.10 per Share).

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, See Instruction 6 for procedure.
