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 obligations
remain. These fees are recognized as operating income to offset the operating
expenses 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 $3,500,000 in
1995. 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.
