ITEM 5.   OTHER EVENTS

     On December 18, 2002 the company filed a lawsuit in District Court,
Arapahoe County, Colorado, against Saturn Electronics & Engineering, Inc.,
Auburn Hills, Michigan. Saturn is the contract manufacturer for the company's
power supply devices.

     The company alleges that Saturn has breached its contract with the company
by overcharging the company for devices made by Saturn for the company, by not
crediting the company for parts inventory purchased by the company and used in
manufacturing, by charging the company for inappropriate expenses unrelated to
the manufacturing process, and by failing to return inventory not used in
manufacturing. The company also alleges unjust enrichment by Saturn at the
company's expense, fraudulent representations by Saturn, tortious interference
with contract and prospective business advantage by Saturn, and breach of
fiduciary duty by Saturn.

     The complaint seeks damages believed to be in excess of $1,400,000, an
accounting for materials and expenses paid to Saturn by the company, and
rescission of the manufacturing contract with Saturn.
