Interest in Securities of the Issuer --------------------------------------------- (a), (b) According to the Issuer's Form 10-Q filed with the Securities and Exchange Commission on November 5, 2007, there were 50,615,672 shares of Common Stock issued and outstanding as of October 26, 2007. Based on such information, the Reporting Persons report beneficial ownership of the following shares of Common Stock: (i) 4,256,551 shares of Common Stock held by Blum L.P. and RCBA Inc. on behalf of the limited partnerships for which Blum L.P. serves as the general partner, which represents 8.4% of the outstanding shares of the Common Stock; (ii) 1,672,900 shares of the Common Stock held by Blum GP II on behalf of the limited partnership for which it serves as the general partner and on behalf of the limited partnership for which it serves as the managing limited partner, which represents 3.3% of the outstanding shares of the Common Stock; (iii) 1,121,318 shares of the Common Stock held by Blum GP III which serves as general partner of Blum GP III LP which, in turn, serves as the general partner of Blum Strategic III, which represents 2.2% of the outstanding shares of the Common Stock; (iv) 22,600 shares of the Common Stock held by Saddlepoint GP on behalf of a partnership for which it serves as the general partner, which represents less than 0.1% of the outstanding shares of the Common Stock; and (v) 177,700 shares of the Common Stock that are legally owned by The Nuclear Decommissioning Trust of Dominion Nuclear Connecticut, Inc. ("Dominion Connecticut"), which represents 0.4% of the outstanding shares of the Common Stock and 177,700 shares of the Common Stock that are legally owned by Virginia Electric and Power Company Qualified Nuclear Decommissioning Trust ("Virginia Electric"), which represents 0.4% of the outstanding shares of the Common Stock, (collectively, the "Investment Advisory Clients"), with respect to which Blum L.P. has voting and investment power. Each Investment Advisory Client has entered into an investment management agreement with Blum L.P., but neither Investment Advisory Client has any contract, arrangement or understanding with the other Investment Advisory Client, or any other Reporting Person, with respect to the acquisition, ownership, disposition or voting of any shares of the Common Stock. Each Investment Advisory Client disclaims membership in a group with any Reporting Person or with the other Investment Advisory Client, and each disclaims beneficial ownership of any shares beneficially owned by the Reporting Persons other than for their own account. Voting and investment power concerning the above shares are held solely by Blum L.P., Blum GP II and Blum GP III. The Reporting Persons therefore may be deemed to be members in a group, in which case the group would be deemed to have beneficial ownership of an aggregate of 7,428,769 shares of the Common Stock, which is 14.7% of the outstanding Common Stock. As the sole general partner of Blum L.P., RCBA Inc. is deemed the beneficial owner of the securities over which Blum L.P. has voting and investment power. The filing of this Schedule shall not be construed as an admission that any of the officers, managing members and members of Blum L.P., Blum GP II, Blum GP III LP and Blum GP III, is, for any purpose, the beneficial owner of any of the securities that are beneficially owned by Blum L.P., Blum GP II, Blum GP III LP or Blum GP III. * * * * * * CUSIP NO. 29481V108 SCHEDULE 13D Page 14 of 15 (c) On December 31, 2007, the Reporting Persons distributed 1,100,467 shares of Common Stock to limited partners in two of the limited partnerships for which Blum LP serves as the general partner and transferred 5,676 shares of Common Stock to Blum LP. (d) Not applicable. (e) Not applicable. Item 6.
