office address at 50 - 52 Av du Chanoine Cartellier, 69230 Saint-Genis Laval,
France.

French citizen with a business address at 50 - 52 Av du Chanoine Cartellier,

proceeding of a judicial or administrative body of competent jurisdiction which

laws, or finding any violations with respect to such laws.

ITEM 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

(the "Stock Exchange") that became effective on March 28, 2001 pursuant to two
separate Share Exchange Agreements (the "Share Exchange Agreements"), both dated
December 13, 2000, among Mymetics and the shareholders of Hippocampe S.A.
("Hippocampe"), which included Dr. Serres. Pursuant to the Share Exchange
Agreements, Mymetics acquired approximately 99.9% of the outstanding shares of
Hippocampe in consideration of an aggregate of approximately 33,311,398 Common
Shares, representing approximately 72% of the currently issued and outstanding
shares of Common Stock.

ITEM 4.    PURPOSE OF TRANSACTION.
