The Stockholders Agreement also grants to the parties thereto (and their permitted transferees) the right, under certain circumstances and subject to certain restrictions, to require the Issuer to register under the Securities Act of 1933, as amended (the “Securities Act”), shares of Common Stock held or acquired by them.

The Issuer

has agreed to indemnify each party thereto (and its permitted transferees, together with certain related parties) against any losses or damages resulting from any untrue statement or omission of material fact in any registration statement or prospectus pursuant to which such holder sells shares of Common Stock, unless such liability arose from the holder’s misstatement or omission, and each party thereto (and its permitted transferees) has agreed to indemnify the Issuer against all losses caused by his (or their) misstatements or omissions.

General

The Reporting Person acquired the shares of the Common Stock reported in this Schedule 13D for investment purposes and intends to review such investment in the Issuer on a continuing basis. Consistent with such purposes, the Reporting Person may engage in communications with, without limitation, one or more stockholders of the Issuer, management of the Issuer and/or one or more members of the board of directors of the Issuer and may make suggestions concerning the Issuer’s operations, prospects, business and financial strategies, strategic transactions, assets and liabilities, business and financing alternatives, the composition of the board of directors of the Issuer and such other matters as the Reporting Person may deem relevant to his investment in the Issuer. In addition, the Reporting Person may from time to time exercise his governance rights as described above. The Reporting Person expects that he will, from time to time, review his investment position in the shares of the Common Stock or the Issuer and may, depending on the Issuer’s performance and other market conditions, increase or decrease their investment position in the Common Stock. The Reporting Person may, from time to time, make additional purchases of shares of the Common Stock either in the open market or in privately negotiated transactions, depending upon his evaluation of the Issuer’s business, prospects, financial condition and results of operations, the market for the Common Stock, other opportunities available to the Reporting Person, general economic conditions, stock market conditions and other factors. Depending upon the factors noted above, the Reporting Person may also decide to hold or dispose of all or part of his investments in the Common Stock and/or enter into derivative transactions with institutional counterparties with respect to the Issuer’s securities, including the Common Stock. Any actions the Reporting Person might undertake may be made at any time and from time to time without prior notice and will be dependent upon the Reporting Person’s review of numerous factors, including, but not limited to: an ongoing evaluation of the Issuer’s business, financial condition, operations and prospects; price levels of the Issuer’s securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; and other future developments.

Except as set forth in this Item 4 or Item 6 below, the Reporting Person has no present plans or proposals that relate to, or that would result in, any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).
