ITEM 3.    SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         The Schedule 13D filed by the Reporting Person on March 8, 2004
reported the issuance by the Company to the Reporting Persons of warrants to
purchase shares of Common Stock and Secured Convertible Promissory Notes
("Notes") pursuant to an Investment Agreement by and among the Company, certain
of the Reporting Persons and Dolphin Direct Equity Partners, L.P.,
(collectively, the "Investor Parties"), which agreement was subsequently amended
and restated, as more fully described in the Schedule 13D (the "Investment
Agreement"). The Schedule 13D amendment No. 1 filed by the Reporting Persons on
April 23, 2004 ("Amendment No. 1") reported the issuance of additional warrants
by the Company to Needham & Co. pursuant to Section 4.14 of the Investment
Agreement, which provides anti-dilution protections to the Investor Parties.
This amendment No. 2 to the Schedule 13D of the Reporting Persons discloses that
the Company has reissued and replaced warrants it issued to certain of the
Reporting Persons pursuant to the Investment Agreement, which warrants were
reported in the Schedule 13D filed by the Reporting Persons on March 8, 2004.
The Company reissued and replaced the following warrants, each dated February
20, 2004, to purchase share of Common Stock at an exercise price of $0.01 per
share because the Company determined upon a recalculation of the application of
the anti-dilution protections of Section 4.14 of the Investment Agreement that
such Reported Persons were entitled to warrants for a smaller amount of shares
of Common Stock than set forth in the original warrants: (i) the Company
replaced a warrant issued to NCPII for 2,435,348 shares of Common Stock with a
warrant for 2,329,425 shares of Common Stock, (ii) the Company replaced a
warrant issued to NCPIIB for 341,375 shares of Common Stock with a warrant for
326,527 shares of Common Stock, (iii) the Company replaced a warrant issued to
NCPIII for 4,263,427 shares of Common Stock with a warrant for 4,077,993 shares
of Common Stock, (iv) the Company replaced a warrant issued to NCPIIIA for
440,307 shares of Common Stock with a warrant for 421,156 shares of Common
Stock, and (v) the Company replaced a warrant issued to NCPIIIB for 849,714
shares of Common Stock with a warrant for 812,756 shares of Common Stock. The
Company also documented the issuance of warrants to Needham & Co. disclosed in
Amendment No. 1 by issuing a warrant dated February 20, 2004 to purchase 31,679
shares of Common Stock at an exercise price of $0.01 per share, which share
amount represents the portion of warrants Needham & Co. was entitled to retain
pursuant to its agreement with Dolphin Direct Equity Partners, L.P. relating to
Needham & Co.'s loan guaranty in favor of the Company disclosed in Amendment No.
