**Comment for Type of Reporting Person:** Pursuant to the Certificate of Designation for the Series B Preferred Stock the Reporting Person may not convert any shares if such conversion would result in the Reporting Person beneficially owning more than 9.9 percent of the outstanding Common Stock The number of shares of Common Stock reported as beneficially owned reflects this limitation
In addition the issuers Preferred A Shares carry supervoting rights exceeding 90 percent of total voting power effectively providing their holder with control of the issuer therefore the Reporting Person does not possess de facto control of the issuer
All percentages reported herein are approximate and have been calculated based on the issuers reported outstanding shares subject to the 9.9 percent ownership limitation applicable to the Series B Preferred Stock pursuant to its Certificate of Designation
The beneficial ownership reported herein excludes any shares of the issuers securities that may be beneficially owned by any entity in which the Reporting Person holds a noncontrolling equity interest as the Reporting Person does not have or share voting or dispositive power over such securities
