In connection with these discussions, the Reporting Persons may, either directly or through one or more affiliates, determine to take any available course of action or to take no course of action and may at any time and from time to time take steps to further or implement such course of action, including any of the events listed in Items 4(a) through 4(j) of Schedule 13D. Any action or actions the Reporting Persons may undertake with respect to their investment in the Issuer or the operations and conduct of the Issuer's business will be dependent upon the Reporting Persons' review of numerous factors, including those listed above, and the Reporting Persons specifically reserve the right to change their intentions, or to formulate plans and proposals, with respect to any or all of the matters described in this paragraph, subject to applicable law and regulations.
