Four New Licensing Agreements with Motient, Visto, ThinAirApps and Mobile Airwaves Demonstrate Crucial Role of Certicom Security Technology that is Designed for the Bandwidth Constraints of Wireless Applications 

HAYWARD, Calif., September 4, 2001 - Certicom, (Nasdaq: CERT; TSE: CIC), today announced four new license agreements that further reinforce its role as a leading enabler of the emerging wireless applications market. Certicom's security software for wireless applications has been licensed to Motient Corporation (Nasdaq: MTNT), Visto, ThinAirApps, Inc., and Mobile Airwaves Inc. 

"These companies represent the new wave of wireless computing and communications that will literally put information directly into the hands of business users and consumers when and where they need it," said Prakash Panjwani, vice president of business development for Certicom. "Innovative application developers have recognized Certicom as the leading provider of trusted security solutions tailored to meet the challenges posed by the constraints of the wireless environment." 

Wireless application development is progressing rapidly. Market research firm Evans Data Corp. recently announced in its "Summer 2001 Wireless Developer Survey" that 60% of application developers surveyed plan wireless application deployment in the next six months. 

The new Certicom licensees are all forging innovative solutions with core Certicom security technology:
