Item 1.01 Entry into a Material Definitive Agreement

     On November 7, 2005, ThermoGenesis Corp. ("TGC") entered into an OEM Supply
Agreement (the "Agreement") with Medtronic, Inc. ("MDT"). Under the terms of the
Agreement,  TGC will supply its Thrombin Processing Device to MDT for use in and
sale with the MDT Magellan  Product  throughout  the world.  The Agreement has a
term of five (5)  years.  TGC's  proprietary  Thrombin  Processing  Device  is a
stand-alone  disposable which produces  autologous thrombin from plasma which is
used  for  topical  hemostasis  and  releasing  growth  factors  from  platelets
(platelet  gel).  MDT's Magellan  Product is used for the production of platelet
gel by combining the concentrated  platelets  produced with a separate  thrombin
source to create a platelet  gel used to  accelerate  wound  healing in surgical
applications.

     The agreement  furthers TGC's strategy to develop  strategic  relationships
with  established  companies  that have the  ability to expand the  distribution
channels for its products and for product line extensions.

     For more  information,  see the  Agreement  attached  as Exhibit 10 and the
