Item 4.

Purpose of Transaction

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

The Reporting Persons acquired beneficial ownership of the shares of Class A common stock reported herein for investment purposes with the aim of increasing the value of their investment and the Issuer. The Reporting Persons intend to review their investment on a regular basis and, as a result thereof, may at any time or from time to time determine, either alone or as part of a group, (i) to acquire additional securities of the Issuer, through open market purchases, privately negotiated transactions, or otherwise, (ii) to dispose of all or a portion of the securities of the Issuer owned by them in the open market, in privately negotiated transactions, or otherwise, or (iii) to take any other available course of action, which could involve one or more of the types of transactions or have one or more of the results specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Exchange Act. Any such acquisition or disposition or other transaction would be made in compliance with all applicable laws and regulations, and subject to the terms and conditions of any agreements between the Reporting Persons and the Issuer.

In this regard, the Reporting Persons are currently evaluating and considering potential transfers of a portion of the shares of Series A Preferred Stock held by them for purposes of syndicating the investment with potential investors in Issuer. There is no assurance that the Reporting Persons will continue to pursue such potential sale or that any such syndication proposal will result in a completed transaction. Continued pursuit and completion of any such transaction is subject to many factors, many of which are outside the control of the Reporting Persons, including, but not limited to, the following: terms believed by the Reporting Persons to be favorable to them, the Reporting Persons’ ongoing assessment of the Issuer’s business and prospects; other developments concerning Issuer and its businesses generally; prevailing market conditions, including the market price of the securities of Issuer; and the availability of other investment opportunities.

In addition, consistent with their investment purpose, the Reporting Persons may engage in communications with persons associated with the Issuer, including shareholders of the Issuer, officers of the Issuer, members of the board of directors of the Issuer, and/or or other third parties, to discuss matters regarding the Issuer, including but not limited to its operations, strategic direction, governance or capitalization, the formation of a syndicate of potential investors in Issuer, and potential business combinations or dispositions involving the Issuer or certain of its businesses. James Stith and Ravi Sarin, each Vice President of AEA Growth Management LP, the registered investment advisor to Equity Fund and Equity Fund Parallel, currently serve as directors of the Issuer and therefore will engage in regular discussions with the Issuer’s board of directors and management as part of their duties as a director.

Notwithstanding anything contained herein, the Reporting Persons intend to review their investment in the Issuer and the Issuer’s performance and market conditions periodically and to take such actions with respect to their investment as they deem appropriate in light of the circumstances existing from time to time. Accordingly, the Reporting Persons specifically reserve the right to change their intention with respect to any or all such matters described above. In reaching any decision as to its course of action (as well as to the specific elements thereof), the Reporting Persons currently expect that they would take into consideration a variety of factors, including, but not limited to, the following: Issuer’s business and prospects; other developments concerning Issuer and its businesses generally; other business opportunities available to the Issuer; changes in law and government regulations; general economic conditions; and prevailing market conditions, including the market price of the securities of Issuer.

Except as set forth in this Item 4, none of the Reporting Persons have a present plan or proposal that relates to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Exchange Act.
