Item 4. Purpose of Transaction

The entities listed above (each a “Reporting Person”) purchased the Common Stock based on the belief that such securities, when purchased, were undervalued and represented an attractive investment opportunity. Although no Reporting Person has any specific plan or proposal to acquire or dispose of the Common Stock, consistent with its investment purpose, each Reporting Person at any time and from time to time may acquire additional Common Stock or dispose of any or all of its Common Stock depending upon an ongoing evaluation of the investment in the Common Stock, prevailing market conditions, other investment opportunities, liquidity requirements of the Reporting Persons, and/or other investment considerations.

The purposes of the acquisitions of the Common Stock were investment. The acquisitions of the Common Stock were made in the ordinary course of business and were not made for the purpose of acquiring control of the Issuer. However, the Reporting Persons have had discussions regarding plans to effect a change in the present board of directors of the Issuer. As a result, the Reporting Persons may be deemed to have formed a “group” under the Securities Exchange Act of 1934, as amended, as of January 30, 2012.

The Reporting Persons currently seek to engage the Issuer’s board of directors in discussions concerning the share ownership by Board members, director compensation levels, capital spending, and corporate governance.

Reporting Persons seek the immediate appointment of new shareholder-designated directors, with full voting rights, to (1) act as shareholder representatives, and (2) promptly begin the formation of an equity committee in the event of a Chapter 11 filing.

Consistent with their investment purpose, the Reporting Persons may engage in communications with one or more stockholders of the Issuer, one or more officers of the Issuer, one or more members of the board of directors of the Issuer, and/or one or more representatives of the Issuer regarding the Issuer, including but not limited to the

Page 8 of 12 Pages

Issuer’s operations and the foregoing current plans of the Reporting Persons. The Reporting Persons may discuss ideas that, if effected may result in a change of the current plans and in the acquisition by persons of additional Common Stock of the Issuer, the disposition of Common Stock of the Issuer, an extraordinary corporate transaction involving the Issuer, and/or other changes in the board of directors of the Issuer or its operations.

Except as disclosed above (relating to paragraphs (d) and (e) of the instructions to Item 4 of Schedule 13D, none of the Reporting Persons has any other plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of the instructions to Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto.

This Schedule 13D is not a solicitation of any action by stockholders of the Issuer. If a proxy statement is completed and filed, stockholders are advised to read the proxy statement when it becomes available because it will contain important information, and stockholders should rely on such proxy statement and not on this Schedule 13D. The proxy statement, if filed, will be available for free at the SEC’s website at http://www.sec.gov.

Item 5. Interest in Securities of the Issuer

(a) and (b) As of November 1, 2011, the Issuer had 19,127,691 shares of Common Stock outstanding based on the information contained in the Issuer’s Form 10-Q for the quarter ended September 30, 2011, filed on November 4, 2011.

As of the date hereof, Mr. King directly owns 601,964 shares of Common Stock (approximately 3.15%).

As of the date hereof, MCP LP owns 400,000 shares (“MCP LP Shares”) of Common Stock (approximately 2.09%) of the issued and outstanding Common Stock. As general partner of MCP LP, MCP LLC may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the MCP LP Shares. MCP LLC does not own any shares of Common Stock directly and disclaims beneficial ownership of the MCP LP Shares. As managing member of MCP LLC, Mr. Morris may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) any shares of Common Stock beneficially owned by MCP LLC. In addition, as of the date hereof, Mr. Morris beneficially owns and has voting and dispositive power over 10,000 shares (“Morris Shares”) of Common Stock (approximately 0.05%) of the issued and outstanding Common Stock. Mr. Morris disclaims beneficial ownership of any shares of Common Stock beneficially owned by MCP LP. MCP LLC, as an entity which is managed by Mr. Morris, may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Morris Shares. MCP LLC disclaims beneficial ownership of Morris Shares.

In addition, the group that may have been deemed to be formed by the Reporting Persons may be deemed to beneficially own the 1,011,964 shares of Common Stock of the Issuer held by all of the Reporting Persons combined (approximately 5.29% of the Common Stock of the Issuer), and each of the Reporting Persons may be deemed to beneficially own the shares of each other Reporting Person.

The filing of this Schedule shall not be construed as an admission that any of the Reporting Persons is, for any purpose, the beneficial owner of the Common Stock held by any other Reporting Person, and each disclaims beneficial ownership of the shares held by the others.
