Note 2. Revenue Recognition

          Product revenues are generally recognized at the time of shipment to 
customers or distributors. Initial license revenues are recorded when earned, 
which is upon signing of the license agreement, confirmation of collectibility
and when no future obligations remain. The Company recognizes license 
termination and conversion fees when earned, which is upon signing of the 
license agreement, confirmation of collectibility and when no future obligation 
remains. These fees are recognized as operating income to recover the operating 
expenses and inventory costs that have been recorded prior to termination or 
conversion of the contract. These operating expenses were incurred by the 
Company to build and supply the expected product pipeline as part of the 
original license agreement. The Company recognized license termination and 
conversion fees of $2,750,000 for the nine months ended September 30, 1997. 
Funded research and other revenues are recorded upon the completion of specific 
milestones or when associated performance obligations are complete. The Company 
recognized a $333,000 initial license fee in its entirety as revenue in the 
three months ended March 31, 1997. The fee was non-refundable in any manner and 
the Company had no further obligations under the contract relating to the 
non-refundable fee.
