The information set forth in Items 3 and 6 of this Schedule 13D is incorporated by reference in its entirety into this Item 4.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis taking into consideration various factors, including the Issuer's business, financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for shares of Class A Common Stock of the Issuer, in particular, as well as other developments and other investment opportunities. Based upon such review, the Reporting Persons will take such actions in the future as the Reporting Persons may deem appropriate in light of the circumstances existing from time to time.

Subject to the Issuer's insider trading policy, any open market or privately negotiated purchases or sales, acquisition recommendations or proposals or other transactions concerning the Issuer may be made at any time without prior notice. Any alternative may depend upon a variety of factors, including, without limitation, current and anticipated future trading prices of the securities, the financial condition, results of operations and prospects of the Issuer and general industry conditions, the availability, form and terms of financing, other investment and business opportunities, general stock market and economic conditions, tax considerations and other factors.

Depending upon each factor discussed above and any other factor (which may be unknown at this time) that is, or may become relevant, the Reporting Persons may consider, among other things: (a) the acquisition by the Reporting Persons of additional securities of the Issuer, the disposition of securities of the Issuer, or the exercise of convertible securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) changes in the present Board of Directors of the Issuer or management of the Issuer; (e) a material change in the present capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer's business or corporate structure; (g) changes in the Issuer's certificate of incorporation, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) causing any class of the Issuer's securities to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) any action similar to those enumerated above.

Except to the extent that the foregoing may be deemed to be a plan or proposal, the Reporting Persons do not currently have any plans or proposals that relate to or would result in any of the actions specified in clause (a) through (j) of this Item 4 of Schedule 13D. Depending upon the foregoing factors and to the extent deemed advisable in light of their general investment policies, or other factors, the Reporting Persons may, at any time and from time to time, formulate other purposes, plans or proposals regarding the Issuer or the shares of Class A Common Stock of the Issuer, or any other actions that could involve one or more of the types of transactions or have one or more of the results described in paragraphs (a) through (j) of this Item 4 of Schedule 13D. The foregoing is subject to change at any time, and there can be no assurance that the Reporting Persons will take any of the actions set forth above.
