The total costs of the Common Stock directly owned by the Funds is approximately $8,929,812.

Item 4.	PURPOSE OF TRANSACTION

The topics of these conversations may cover a range of issues, including those relating to the Issuer’s business, management, board composition (which may include adding or proposing a candidate or candidates supported by the Reporting Persons to the board of directors of the Issuer (the “Board”)), operations, capital allocation, asset allocation, capitalization, corporate structure, dividend policy, financial condition, mergers and acquisitions strategy (which may include a potential strategic review or sale process involving the Issuer or certain of the Issuer’s businesses or assets, including transactions in which the Reporting Persons or their affiliates may seek to participate and potentially engage in), overall business strategy and plans, executive compensation, organizational documents and corporate governance matters.

CUSIP No. 294100102 SCHEDULE 13D Page 13 of 16 Pages

The Reporting Persons intend to review their investment in the Issuer on a continuing basis and depending upon various factors, including without limitation, the Issuer’s financial position and strategic direction, actions taken by the Issuer, the outcome of any discussions or actions referenced above, overall market, general economic and industry conditions, other available investment opportunities, and the availability of securities of the Issuer at prices that would make the purchase or sale of such securities desirable, it may endeavor (i) to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Common Stock and/or other equity, debt, derivative securities or other instruments that are convertible into Common Stock, or are based upon or relate to the value of the Common Stock or the Issuer (collectively, “Securities”) on the open market or in private transactions, including through a trading plan created under Rule 10b5-1(c) or otherwise, on such terms and at such times as the Reporting Persons may deem advisable and/or (ii) to enter into transactions that increase or hedge their economic exposure to the Common Stock or other Securities without affecting any Reporting Person’s beneficial ownership of the Common Stock or other Securities.  In addition, the Reporting Persons may, at any time and from time to time, (i) review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto and (ii) propose or consider one or more of the actions described in subparagraphs (a) – (j) of Item 4 of Schedule 13D.
