Section 1 - Registrant's business and operations

Item 1.02 Termination of material definitive agreement.

We notified  Laboratorios  Del Dr. Esteve,  S.A.  ("Esteve") of our intention to
terminate  the  license   agreement  that  gives  Esteve  the  right  to  market
Ampligen(R) for CFS in Spain, Portugal and Andorra. The basis of the termination
was  non-performance  by  Esteve  of  certain  contractually  required  clinical
trials. Negotiations  were ongoing but amicable resolution could not be reached.
Esteve, as is its right under the license  agreement,  has filed for arbitration
seeking  damages.  We  believe  their  claim is  without  merit  and  intend  to
counterclaim, seeking damages.
