     The University as Operator of Argonne National Laboratory under Contract
No. W-31-109-ENG-38 with the U.S. Department of Energy (DOE) conducts
research and development at the Laboratory. An invention entitled
"Calcination and Solid State Reaction of Ceramic-Forming Components to
Provide Single-Phase Superconducting Materials Having Fine Particle Size" was
conceived by the University in the course of and under said Contract and is a
Subject Invention under said Contract in accordance with the terms and
conditions thereof.

     The University is entitled to elect title to and obtain patents for
Subject Inventions generated under such Contract, and to license patent

U.S. Patent No. 5,086,034 claiming the invention.

     SCI, a small business, manufactures its products in the United States. SCI
was a collaborator with the University under HTS Pilot Center Agreement #85287
to determine the commercial desirability of the vacuum calcination process
covered by said Subject Invention. SCI desires certain rights in and to said
Subject Invention principally for the manufacture and sale of high temperature
superconducting (HTS) powders and products made from HTS powders.

     NOW, THEREFORE, the Parties agree as follows:
