______________

¹ The percentage ownership of each Reporting Person, determined in accordance with Rule 13d-3(d) under the Securities Exchange Act of 1934 has been calculated by dividing (i) the sum of the aggregate number of outstanding shares of Common Stock beneficially owned by such Reporting Person and the number of shares of Common Stock issuable upon exercise of the Warrants, beneficially owned by such Reporting Person by (ii) the sum of the 20,031,710 shares of Common Stock reported by the Company to be outstanding pursuant to its Report on Form 10-Q for the period ended October 30, 2010 and the number of shares of Common Stock issuable upon exercise of the Warrants beneficially owned by such Reporting Person.

Of the shares reported as beneficially owned in this Schedule 13D, 3,383,930 shares are owned directly by Lenado Partners, 424,748 shares are owned directly by a private investment partnership with Lenado Capital as its general partner and Lenado Advisors as its manager, 174,537 shares are owned directly by SPV UNO, 2,684,860 shares are owned by EnterAspen, of which 1,349,679 are owned through an account managed by Aspen Advisors and of which 1,335,181 are owned through an account managed by Lenado Advisors.

Each of Lenado Advisors and Lenado Capital disclaims any beneficial interest in the Common Stock owned by the accounts managed by Lenado Advisors and Aspen Advisors.
