The purpose of the acquisition of the Preferred Stock by the Reporting Persons was for investment and to give the Reporting Persons certain management rights for purposes of maximizing the long-term value of the Company. The purpose of the acquisition of the Common Stock by the Reporting Persons was for investment. The holders of Preferred Stock are entitled to such number of votes as shall entitle them in the aggregate to 51% of the total voting power of the capital stock of the Company, except that the holders of Preferred Stock shall only have the right to one vote for each share of Common Stock into which such holders' shares of Preferred Stock are convertible in the case of a vote with respect to (i) a sale of all or substantially all of the assets of the Company which values the Company at less than $50,000,000 or (ii) a merger transaction in which the Company is to be acquired which values the Company at less than $50,000,000. In addition, a holder of Preferred Stock shall only be entitled to one vote for each share of Common Stock into which such holder's shares of Preferred Stock are convertible if the holders of Preferred Stock default on their obligations under the Purchase Agreement to purchase additional Preferred Stock. So long as GEF and NV have the 51% voting rights to which they are entitled under the terms of the Preferred Stock, they have agreed to vote any shares of Common Stock owned by them in the same proportions as shares of Common Stock are voted by the other holders of Common Stock. Transfer of the Preferred Stock may only be made to affiliates of GEF and NV. The Purchase Agreement provides that GEF and NV may at any time request the Company to convene a meeting of shareholders for the purpose of electing designees of GEF and NV to fill a majority of the seats of the Company's Board of Directors. On December 4, 2000, at the Company's annual meeting of stockholders, Mr. Leonard, Mr. Hannon, Ms. Pisano and Ms. Minton were elected to the Board of Directors of the Company and now comprise four of the Company's nine directors. If not sooner converted, the Preferred Stock shall be automatically converted to Common Stock on September 8, 2002, at which time the 51% voting rights of the holders of Preferred Stock described above would cease to be effective. The Reporting Persons reserve the right to acquire, or cause to be acquired, additional securities of the Company, to dispose of, or cause to be disposed of, such securities at any time or to formulate other purposes, plans or proposals regarding the Company or any of its securities, to the extent deemed advisable in light of general investment and trading policies of the Reporting Persons, market conditions or other factors. CUSIP No. 296744 10 5 13D/A Page 21 of 36 Item 5. Interest in Securities of the Issuer. (a) Each of GEF, GECC, Mr. Leonard, Ms. Minton, Mr. Gregory, NV, Mr. Hannon and Ms. Pisano may be deemed the beneficial owner of 2,757,700 shares of Common Stock.

A copy of the Shareholders Voting Agreement is attached hereto as Exhibit 3. (ii) GEF, GECC, Mr. Leonard, Ms. Minton and Mr. Gregory may be deemed to have the sole power to direct disposition of the 1,000,000 shares of Common Stock issuable upon conversion of the 250,000 shares of Preferred Stock held for the account of GEF, the 330,000 shares of Common Stock held for the account of GEF, and the 97,700 shares of Common Stock held for the account of GECC.

(d) The members of GEF have the right to participate in the receipt of dividends from, or proceeds from the sale of, the stock held by GEF in accordance with their membership interests in GEF. The members of GECC have the right to participate in the receipt of dividends from, or proceeds from the sale of, the stock held by GECC in accordance with their membership interests in GECC.

(e) Not applicable. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer. The Purchase Agreement provides for the purchase of the Preferred Stock by GEF and NV and the issuance of the Warrants to GEF and NV. Under the Purchase Agreement, GEF and NV each purchased an aggregate of 250,000 shares of Preferred Stock. The Company makes customary representations and warranties to GEF and NV and has agreed as soon as practicable to secure the listing on the Nasdaq Stock Market of the shares of Common Stock issuable upon conversion of the Preferred Stock and exercise of the Warrants. In connection with the execution and delivery of the Purchase Agreement, the Company approved Articles of Amendment of its Articles of Incorporation, which set forth the terms of the Preferred Stock, including the provisions concerning voting rights described above.
