Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to
Securities of the Issuer.

                  Item 6 is hereby amended and supplemented by the addition of
the following:

RESTRUCTURING AGREEMENT

                  The Company's Board of Directors has approved a nonbinding
preliminary term sheet that provides for, upon the terms and subject to the
conditions set forth therein, including the approval of the Company's existing
holders of its common stock, a conversion (the "Conversion") of the Series A
Preferred Stock into shares of common stock representing approximately 73% of
the post-conversion capitalization of the Company.

                  In connection with the Conversion, on September 29, 2004, the
Company and certain holders of its Series A Preferred Stock entered into a
restructuring agreement and a voting agreement and proxy whereby such holders of
the Series A Preferred Stock have agreed to vote in favor of an amendment to the
Company's certificate of incorporation providing for the conversion of all
outstanding shares of Series A Preferred Stock into approximately 11.6 million
shares of the Company's common stock. The holders of the converted shares would
have rights to register for resale the shares of common stock received in the
Conversion. The proposed transaction is subject to approval of the Company's
stockholders.

                  The Restructuring Agreement provides that holders of the
Series A Preferred Stock who are signatories to such Restructuring Agreement
agree to consent to the Conversion. The Voting Agreements each provide that the
applicable holder of Series A Preferred Stock will vote all of its Series A
Preferred Stock in favor of the Conversion. The Irrevocable Proxies each
authorize the Company to vote the shares of Series A Preferred Stock owned by
the applicable holder in favor of the Conversion.

                  By virtue of the Voting Agreements, the Reporting Persons may
be deemed to be a group (within the meaning of Section 13(d)(3) of the Act) with
the holders of Series A Preferred Stock (other than the Reporting Persons)
parties to such Voting Agreements and, as a result, may be deemed to have
beneficial ownership of the Series A Preferred Stock beneficially owned by such
persons. The holders of the Series A Preferred Stock who are signatories to the
Voting Agreements other than the Reporting Persons, and the share amounts
beneficially owned by such persons are as follows: (i) Granite Private Equity
III, LLC, beneficial owner of 85 shares of Series



CUSIP No. 28225C103


A Preferred Stock; (ii) Gunjan Sinha, beneficial owner of 50 shares of Series A
Preferred Stock; (iii) Ashutosh Roy, beneficial owner of 30 shares of Series A
Preferred Stock; (iv) Promod Narang, beneficial owner of 10 shares of Series A
Preferred Stock; (v) Eric Smit, beneficial owner of 10 shares of Series A
Preferred Stock; and (vi) Henkel-Wallace Family Trust, beneficial owner of 25
shares of Series A Preferred Stock. The Reporting Persons disclaim such
beneficial ownership and are filing this Schedule 13D on behalf of themselves
and not on behalf of any other person or entity. The Company intends to solicit
approval of the Conversion from the holders of its Common Stock.

                  The foregoing description of the Restructuring Agreement,
Voting Agreements and Irrevocable Proxies is not, and does not purport to be,
complete and is qualified in its entirety by reference to such agreements. A
copy of the Restructuring Agreement, which includes as exhibits the form of
Voting Agreement and the form of Irrevocable Proxy, is attached as an exhibit
hereto.


Item 7. Material to be Filed as Exhibits.

                  Item 7 is hereby amended and supplemented by the addition of
the following:

Exhibit 1 - Restructuring Agreement by and between the Company and each holder
of Series A Preferred Stock dated as of September 29, 2004 (incorporated by
reference to Exhibit 10.1 to the Company's Current Report on Form 8-K filed with
the Commission on September 30, 2004).

Exhibit 2 - Joint Filing Agreement among the Reporting Persons, dated October 1,
2004.
