The Amended and Restated Technology Commercialisation and License Agreement, signed in 2013 between Silex and GLE, is an exclusive worldwide license for exploitation of the SILEX technology for uranium enrichment. Silex’s  acquisition of a 51% interest in GLE does not affect the license agreement between Silex and GLE, under which Silex will be entitled to a perpetual royalty of a minimum of 7% on revenues generated by GLE from any future use of the SILEX technology, including the Paducah commercial plant opportunity. 

Further milestone payments of US$20m will also be payable to Silex in the event the SILEX technology is commercialised by GLE.

A US$15m milestone payment was also received by Silex in July 2013. This was  triggered by the successful completion of the Test Loop Phase 1 Program Milestone: Technology Demonstration and Validation.
