The Reporting Person pursues an investment objective that seeks capital appreciation. In pursuing this investment objective, the Reporting Person analyzes the operations, capital structure and markets of companies in which the Reporting Person's clients invest, 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. The Reporting Person will continuously assess the Issuer's business, financial condition, results of operations and prospects, general economic conditions, the securities markets in general and those for the Shares in particular, other developments and other investment opportunities. Depending on such assessments, the Reporting Person may acquire additional Shares or may determine to sell or otherwise dispose of all or some of the Shares presently held by AJR, Cambrian Fund, and the Managed Accounts in the open market or in private transactions.

The Reporting Person will continue its active discussions with the Issuer's management with respect to actions which might be taken by the management of the Issuer to maximize shareholder value of the Issuer. In addition, the Reporting Person may hold discussions with other parties who might engage in shareholder value enhancing activities for the benefit of all of the Issuer's shareholders.
