The Management Company is the sole general partner of the Domestic Fund and the investment adviser to the Domestic Fund and the Offshore Fund (collectively, the “Funds”). The Funds directly own the Common Stock to which this Schedule 13D relates, and the Reporting Persons may be deemed to have beneficial ownership over such Common Stock by virtue of the authority granted to them by the Funds to vote and to dispose of the securities held by the Funds, including the Common Stock.

In such instances, the positions held in the accounts are pledged as collateral security for the repayment of debit balances in the accounts.

 The purpose of the acquisition of the shares of Common Stock by the Funds is for investment. The Reporting Persons may cause the Funds to make further acquisitions of Common Stock from time to time or to dispose of any or all of the shares of Common Stock held by the Funds at any time.

The Reporting Persons are engaged in the investment business. In pursuing this business, the Reporting Persons analyze the operations, capital structure and markets of companies, including the Issuer, on a continuous basis through analysis of documentation and discussions with knowledgeable industry and market observers and with representatives of such companies (often at the invitation of management). From time to time, one or more of the Reporting Persons may hold discussions with third parties or with management of such companies in which the Reporting Person may suggest or take a position with respect to potential changes in the operations, management or capital structure of such companies as a means of enhancing shareholder value. Such suggestions or positions may relate to one or more of the transactions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Exchange Act, including, without limitation, such matters as disposing of or selling all or a portion of the company or acquiring another company or business, changing operating or marketing strategies, adopting or not adopting certain types of anti-takeover measures and restructuring the company’s capitalization or dividend policy.

Except as set forth above, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions required to be described in Item 4 of Schedule 13D. Each of the Reporting Persons may, at any time, review or reconsider its position with respect to the Company and formulate plans or proposals with respect to any of such matters.
