Explanation of Responses:

* 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) The terms of the Series G Convertible Preferred Stock contain a limitation on conversion which prevents the Reporting Person from converting shares of Series G Convertible Preferred Stock into Shares of Common Stock if, after giving effect to the conversion, the Reporting Person would beneficially own more than 4.99% of the outstanding shares of Common Stock. The Reporting Person may elect to increase this limitation to 9.99%, 14.99% or 19.99%, upon not less than 61 days prior written notice to the Company. Since the Reporting Person currently beneficially owns less than 4.99% of the outstanding shares of Common Stock, the conversion limitation that applies to the Reporting Person is the 4.99% limitation. The Reporting Person disclaims beneficial ownership of such securities except to the extent of the Reporting Person's pecuniary interest in such securities.
(2) Pursuant to a certain Securities Purchase Agreement, dated July 6, 2012, among the Company, the Reporting Person and the other purchasers named therein, the Reporting Person purchased 20 "Units" at a purchase price of $5.00 per Unit. Each Unit consisted of (i) one share of Series G Convertible Preferred Stock, convertible into 10 shares of the Company's Common Stock and (ii) a warrant to purchase 5 shares of Common Stock, which warrant is exercisable until July 6, 2015.
(3) The Series G Common Stock Purchase Warrants contain a limitation on exercise which prevents the Reporting Person from exercising any Warrants if, after giving effect to the exercise, the Reporting Person would beneficially own more than 4.99% of the outstanding shares of Common Stock. The Reporting Person may elect to increase this limitation to 9.99%, 14.99% or 19.99%, upon not less than 61 days prior written notice to the Company. Since the Reporting Person currently beneficially owns less than 4.99% of the outstanding shares of Common Stock, the conversion limitation that applies to the Reporting Person is the 4.99% limitation. The Reporting Person disclaims beneficial ownership of such securities except to the extent of the Reporting Person's pecuniary interest in such securities.
