Agreement Allows for Large Scale Deployment of Certicom's ECC Technology Across RIM's Full Line of Wireless Handhelds 

HAYWARD, CA., and WATERLOO, Ont., July 24, 2000 - Certicom (Nasdaq: CERT and TSE: CIC), a leading provider of mobile e-commerce security, and Research In Motion Limited (TSE: RIM and Nasdaq: RIMM), a world leader in the mobile communications market, today announced an alliance which will enable RIM to utilize Certicom's elliptic curve cryptography (ECC) technology throughout its wireless product offerings, including the new RIM 957 Wireless Handheld™. The agreement provides for large-scale deployment of Certicom's high performance, efficient ECC within RIM's leading wireless products enabling mobile commerce applications that require the ability to conduct trusted and secure transactions and communications over the wireless Internet.

The agreement enables RIM to use Certicom's high performance security products, such as WTLS Plus™, SSL Plus™ and the Security Builder® cryptographic toolkit for a broad range of RIM products. Using Certicom's security technology, RIM's development community can provide secure, end-to-end mobile commerce solutions for a broad range of customers, including carriers, financial institutions, and application service providers.

As part of the alliance, RIM will use Certicom's ECC technology and include support for Certicom's MobileTrust digital certificates in RIM's handheld security architecture. Supporting Certicom's MobileTrust root key in RIM's handheld security architecture will provide for high-speed digital signature generation on RIM handhelds, which allows both parties in a transaction to identify one another.

Digital signature verification (customer authentication) is the Internet equivalent of traditional hand-written signatures. Unique to Certicom's MobileTrust security offering will be the ability to provide digital signature capability to the mobile device itself, not only to the server.

"This agreement with Certicom, a leader in ECC wireless security technology, will enable RIM to provide the market with the secure mobile devices they require for m-commerce transactions," said David Yach, Vice President, Software at Research In Motion. "Certicom has established products that deliver efficient, easy-to-implement solutions that will complement and enhance RIM's market leading wireless solutions."

RIM Wireless Handhelds™ are widely deployed and distributed through leading solution providers including Aether Systems, BellSouth Wireless Data, Compaq Computer, Dell Computer, GoAmerica, Motient, PageNet, Rogers AT&T Wireless, SkyTel as well as various leading Internet Service Providers. In addition to wireless email, personal organizer, paging, intranet and Internet applications, RIM Wireless Handhelds support a broad range of mobile commerce applications, including authenticated transactions for wireless banking, stock trading and consumer purchases.

"Research in Motion is a clear leader in the wireless communications world and we are excited to expand our relationship in order to deploy our trusted ECC security technology within their highly acclaimed products," said Richard Depew, Certicom executive vice president, field operations. "We believe the adoption of Certicom's ECC within the RIM product line is yet another strong endorsement of the technology and the significant performance and efficiency advantages it can offer leading m-commerce OEMs."

About Elliptic Curve Cryptography
Developed for a broad range of computing platforms and maximum interoperability, Certicom's Elliptic Curve Cryptography (ECC) technology enables strong, high performance security for many pieces of the computing infrastructure, including the new generation of small form-factor products such as handheld computers, pagers, cell phones and smart cards. Certicom's patented implementation of ECC technology provides a more efficient alternative to conventional public key cryptographic algorithms in many mobile and wireless environments, allowing for faster processing speed, reduced bandwidth usage and decreased battery requirements. These advantages make Certicom's ECC-based security technology particularly well suited to mobile devices that incorporate less powerful processors, such as handheld computing devices, Internet-enabled phones and two-way pagers.
