Members of Vicis Capital, LLC

The business address of each of the Insiders is 445 Park Avenue, Suite 1043, New York, NY 10022. To Vicis’s knowledge, each of the Insiders is a United States citizen, and none of the Insiders has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). On September 18, 2013, without admitting or denying the findings of the Securities and Exchange Commission (the “SEC”), Shad Stastney consented to the entry of an administrative order (the “Order”) by the SEC instituting administrative and cease-and-desist proceedings pursuant to Sections 203(f) and 203(k) of the Investment Advisers Act of 1940, as amended (the “Advisers Act”), and Section 9(b) of the Investment Company Act of 1940, as amended.  The order, entitled In the Matter of Shadron L. Stastney, resolved issues relating to a failure to disclose a material conflict of interest to the trustee of the Fund and the engagement in an undisclosed principal transaction with the Fund.  In conjunction with the Order, Mr. Stastney agreed to cease and desist from committing or causing any violations and any future violations of Sections 206(2) and 206(3) of the Advisers Act, to be barred from association with any investment adviser, broker, dealer, municipal securities dealer, or transfer agent and prohibited from serving or acting as an employee, officer, director, member of an advisory board, investment adviser or depositor of, or principal underwriter for, a registered investment company or affiliated person of such investment adviser, depositor, or principal underwriter, with the right to apply for reentry after eighteen months (except that he may continue to remain associated with Vicis as a managing member solely for the purpose of engaging in activities and taking actions that are reasonably necessary to wind down the Fund, subject to the oversight of an independent monitor paid for by Mr. Stastney), and pay disgorgement of $2,033,710.46, prejudgment interest of $501,385.06, and a civil monetary penalty of $375,000. To Vicis’s knowledge, no other Insider has, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration

The Fund previously acquired 13,297,083 shares of Common Stock.

On July 31, 2013, the Fund sold 1,600,000 shares of Common Stock in a series of four privately negotiated transactions. In consideration thereof, the Fund received four fully collateralized secured promissory notes each in the principal amount of $600,000 (or a price per share of $1.50) and bearing interest at a rate of 0%.

On August 9, 2013, the Fund sold 1,600,000 shares of Common Stock in a series of three privately negotiated transactions. In consideration thereof, the Fund received two fully collateralized secured promissory notes in the principal amount of $600,000 and $1,200,000, respectively (at a price per share of $1.50) and bearing interest at a rate of 0%, and one fully collateralized secured promissory notes in the principal amount of $440,000 (at a price per share of $1.10). As a result of the foregoing transactions, Vicis may be deemed to beneficially own 10,097,083 shares of Common Stock.

Item 4. Purpose of Transaction.

Vicis, on behalf of the Fund, has acquired and disposed of the Common Stock for investment purposes in the ordinary course of its business pursuant to specified investment objectives of the Fund.

In connection with a July 31, 2007 purchase by the Fund from the Issuer of a certain Senior Secured Convertible Promissory Note, the Fund acquired the right, until such time as the Fund’s fully diluted ownership of the Issuer is less than 10%, to designate one member of the Issuer’s Board of Directors, or, in the event that the number of directors on the Issuer’s Board of Directors is greater than five (5), the right to designate the number of members of the Issuer’s Board of Directors equal to the product (such product rounded up) of (x) the Fund’s fully diluted ownership of the Issuer, multiplied by (y) the total number of directors of the Issuer. The Fund previously designated Shad Stastney as its designee pursuant to this right, and Mr. Stastney was elected a director of the Issuer at the Issuer’s Annual Meeting of Stockholders held on June 27, 2008. On September 17, 2013, Mr. Stastney resigned from the Issuer’s board of directors, and the Fund has not designated any other individual to serve as a member of the Issuer’s Board of Directors pursuant to such right at this time.

Vicis and representatives of Vicis and the Fund have had discussions with senior management of the Issuer and may in the future have such discussions concerning ways in which the Issuer could maximize shareholder value.

Except as set forth in this Item 4, Vicis has no present plan or proposal that relates to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Act, but will continue to review this position based upon further developments.

As permitted by law, Vicis may purchase shares of Common Stock or other securities convertible, exchangeable or exercisable into Common Stock or dispose of any or all of such securities from time to time in the open market, in privately negotiated transactions, or otherwise, depending upon future evaluation of the Issuer and upon other developments, including general economic and stock market conditions.

Item 5. Interest in Securities of the Issuer

The foregoing 10,097,083 shares of Common Stock represent approximately 60.6% of the Issuer’s outstanding Common Stock (based upon 16,664,553 shares of Common Stock outstanding at August 13, 2013, as reported by the Issuer in its Quarterly Report on Form 10-Q filed with the SEC on August 14, 2013, and 10,097,083 shares of Common Stock deemed to be beneficially owned by Vicis).

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

 The information set forth in Items 3 and 4 is hereby incorporated by reference in this Item 6.

On August 12, 2013, the Fund and the Issuer entered into a financing arrangement pursuant to a Note Purchase Agreement. Under the terms of the Note Purchase Agreement, the Fund agreed to fund up to $5,000,000 cash to the Issuer, funded in increments of $500,000 each time prior to June 30, 2014 that the Issuer certifies to the Fund that its available cash falls below $500,000, in exchange for which the Fund would receive a senior secured note (payable solely in cash and not convertible into equity securities of the Issuer) due June 30, 2014, and bearing interest at 12%. No amounts have been funded to the Issuer pursuant to this arrangement as of the date hereof.
