The DAS Group, a SUBSIDIARY OF DAS INC., is developing new products for the
treatment and prevention of drug addiction and alcoholism.

DAS S.A.S. is developing some of its products at its laboratory in the
Pharmacy Department in Paris, with which DAS S.A.S., signed an agreement for
the occupancy of premises and for the provision of services on JULY 17, 1997.

DAS is developing the COC-AB product worldwide through various companies that
are members of the DAS Group.  An agreement was signed on September 6, 1999
with the University for the COC-AB product, concerning compensation and the
intellectual property rights relating to the provision of development and
other services provided by the University.

Patent applications have been filed for these antibodies in Europe and in the
United States of America, exclusively in the name of DAS Inc.

<PAGE>

In Europe, DAS S.A.S. today (the date of signature of this Agreement), hired
a research team for the development of its products (5 individuals), signed
contracts with specialized consultants to monitor its research, and set up a
European scientific committee (6 French researchers).

The laboratory of Professor Galons (Organic Chemistry Laboratory II
(LABORATOIRE DE CHIMIE ORGANIQUE II) in the Pharmacy Department at Universite
Rene Descartes does most of its work in the following area of research:
cellular and molecular biology applied to diagnosis and treatment.  Its field
of research includes but it is not limited to fundamental research on
methamphetamine immunogens and dopamine receptor ligands, which are the
subject of this agreement for the commercial exploitation of research.

Pursuant to Act no. 99-587 on Innovation and Research of July 12, 1999, the
University wishes, by means of this contractual agreement, to develop
cooperation with DAS for the commercial exploitation of the research

to provide it with services for the development of products for the treatment
and prevention of drug addiction and alcoholism other than the COC-AB
antibodies.  Research may also be performed and services provided by Organic
Chemistry Laboratory 2 (LABORATOIRE DE CHIMIE ORGANIQUE 2) headed by
Professor Herve Galons, in accordance with future, individual agreements for
