RE:    New Technology of Drug Delivery Systems

Joe,

Per our discussions, any patents covering inventions created individually by 
you or jointly with members of CIMA staff during our interaction to develop 
new enabling drug delivery technology are to be assigned to CIMA LABS INC.  
Once the patent applications are on file, we would then develop and sign an 
agreement which would provide you a royalty equal to [...***...] of all CIMA 
sales of products developed covered by patents issuing from such patent 
applications and marketed either by one of our partners or by CIMA itself for 
the life of the patent.

It is CIMA's understanding that all such inventions described above will be 
owned by you and not the University of Wisconsin.  If this arrangement is 
acceptable to you, please signify your acceptance by signing and dating 
below. Please return the original to me and keep a copy for yourself.

Sincerely,



 /s/ John M. Siebert
