OTHER EVENTS On July 20, 2001, Nanogen, Inc. entered into a settlement agreement with Motorola, Inc., Genometrix, Inc. and the Massachusetts Institute of Technology concluding the declaratory judgment action by Nanogen against Motorola, Genometrix and MIT and Motorola's counterclaim against Nanogen. Nanogen had filed its complaint in April 2000, alleging inter alia non-infringement and invalidity of U.S. Patent No. 5,653,939, entitled "Optical and Electrical Methods and Apparatus for Molecular Detection" (the "'939 Patent"), and Motorola filed a counterclaim in May 2000, alleging inter alia infringement of the '939 Patent. In connection with the settlement, Nanogen has secured a license from Motorola to certain claims of the '939 Patent. In exchange, Nanogen will make a one-time aggregate payment of $2.5 million in cash and issue another $2.5 million in Nanogen common stock to the parties involved. The settlement does not include any cross-licensing provisions of Nanogen technology to Motorola, Genometrix or MIT. The lawsuit has now been dismissed. The license grant from Motorola follows the grant of a license to Nanogen to the '939 Patent from Beckman Coulter, Inc. in May 2000. The '939 Patent was originally granted to MIT, which licensed the '939 Patent to Beckman Coulter, Inc. in 1993. In 1994, MIT licensed the '939 Patent to Genometrix, Inc., which subsequently granted sublicensing rights to Motorola in 1999. Item 7.
