ITEM 1. CHANGES IN CONTROL OF REGISTRANT.

A change of control of the Registrant occurred on October 4, 2000, when
Eurovest, Inc. ("Eurovest"), a Nevada corporation controlled by Dr. Terry
Washburn (who is a member of the Board of Directors of the Registrant), acquired
a total of 147,350,980 shares of the Registrant's common stock from Marc Elalouf
("Elalouf") and Patrice Lambert (and from Lambert's affiliate, Queue
Communications, Ltd.) (collectively, "Lambert"), each of whom were deemed
control persons of the Registrant. The 147,350,980 shares represent
approximately 19.75% of the Registrant's issued and outstanding shares.

As a result of the transaction, neither Elalouf nor Lambert have a controlling
interest in the Registrant. Eurovest, upon consummation of the transaction,
cancelled 144,850,980 of the 147,350,980 shares conveyed by the former control
persons, leaving 2,500,000 shares beneficially owned by Dr. Terry Washburn,
Director of the Registrant. One million (1,000,000) of the aforesaid 2,500,000
shares are being held as a contingent reserve against delivery of 1,000,000
shares by Lambert for cancellation.

The parties, on October 4, 2000 entered into a Stock Purchase Agreement whereby
Elalouf and Lambert exchanged the 147,350,980 shares of the Registrant for 100%
of the outstanding shares of Externet World, Inc., a California corporation,
which is wholly owned by Eurovest.

Pursuant to Item 403(c) of Regulation S-K, the Registrant knows of no
arrangements, including a pledge by any person of securities of the Registrant
or any of its parents, whereby the operations of which may at a subsequent date
result in a change in control of the Registrant.
