ITEMS 1-10 OF AMENDMENT NO. 3
AND RESTATEMENT OF SCHEDULE 13G
OF PGS INTERNATIONAL N.V.,
A NETHERLANDS CORPORATION
This restated Schedule 13G is being filed by PGS International
N.V., a Netherlands corporation ("PGS Netherlands") to report the sale of
165,000 shares of Common Stock of Corvas International, Inc. (the "Company")
(the "Shares") by Chelsea N.V. ("Chelsea") and thereby reducing the beneficial
ownership of PGS Netherlands from 1,334,793 Shares to 1,169,793 Shares.
On February 12, 1993, Plant Genetic Systems, N.V., a Belgian
corporation ("PGS") filed a Schedule 13G to report beneficial ownership of
1,334,793 Shares. The Shares were held through Chelsea, a wholly owned
subsidiary of PGS. Through Chelsea, PGS had sole power to direct the vote and to
direct the disposition of the Shares.
The Schedule 13G was amended on February 16, 1994 to report the
sale of 300,000 Shares by Chelsea to PGS International N.V., a Belgian
corporation ("PGS Belgium"). PGS Belgium owns 100% of the stock of PGS. The
Amendment No. 1 to the Schedule 13G specified that PGS Netherlands was organized
in November 1993 through a share exchange by the shareholders of PGS Belgium and
exercised sole voting and investment control over the Shares still held by
Chelsea and PGS Belgium.
The Schedule 13G was amended on February 3, 1997 to report the
acquisition of PGS Netherlands by Hoechst Schering AgrEvo GmbH, a German
corporation ("Hoechst Schering AgrEvo"). Hoechst Schering AgrEvo was a
joint-venture owned by Hoechst AG ("Hoechst") and Schering AG ("Schering"). Both
Hoechst and Schering were German corporations. The Amendment No. 2 to the
Schedule 13G specified that as a result of the acquisition by Hoechst Schering
AgrEvo, PGS Netherlands was no longer PGS Belgium's and Chelsea's ultimate
parent company. PGS Netherlands became a wholly owned subsidiary of Hoechst
Schering AgrEvo. PGS Netherlands was still holding the Shares through Chelsea
and PGS Belgium, but was sharing voting and investment control over the Shares
with its direct parent company Hoechst Schering AgrEvo.
