         Certicom Partners with MoneyStream Services to Provide Advanced
         Security for New E-Commerce Solutions and Innovative Banking Services

         LEADING CANADIAN E-COMMERCE & TRANSACTION PAYMENT PROVIDER TO UTILIZE
         CERTICOM'S SSL PLUS, ECC AND MOBILETRUST OFFERINGS

         HAYWARD, CA, May 1 /CNW/ - Certicom, a leading provider of m-commerce
security, and MoneyStream Services, Canada's only full service electronic
payment processing company, today announced that MoneyStream has licensed
Certicom encryption technology to provide highly secure, innovative online
financial services to its customers. Under the agreement, MoneyStream will use
Certicom's SSL Plus(TM) technology to secure its powerful electronic payment
gateway technologies. Also announced today is MoneyStream's agreement to enable
trusted financial transactions utilizing Certicom's MobileTrust service.

         "Security is a critical business standard that is paramount to our
success in meeting our customers' e-business requirements," said Joey Roa, vice
president of technology for MoneyStream. "It is essential that our payment
processing solution provide for optimal end-to-end security. Certicom's proven
SSL Plus will provide a premier security protocol. In addition, we view
Certicom's MobileTrust service as an important piece of our infrastructure that
will enable signed business transactions."

         Certicom's SSL Plus toolkit is the industry's most widely deployed
commercial Secure Sockets Layer (SSL) product, due largely to its ease of use,
rapid development time, and support for RSA, DSA/Diffie-Hellman, and elliptic
curve cryptography (ECC) - the only commercial SSL product with that capability.
MoneyStream is using Certicom's SSL Plus to provide a secure link for its
clients that perform financial transactions utilizing the Internet.

         Headquartered in Calgary, Alberta, MoneyStream is dedicated to
delivering a full suite of online financial solutions. MoneyStream's secure,
reliable and cost effective e-commerce and transaction processing solutions
offer users a one-stop, full-service alternative to administering all facets of
e-business payment processing.

         "MoneyStream is on the cutting edge of delivering convenient electronic
financial services to businesses and consumers," said Rick Dalmazzi, president
and CEO of Certicom. "A very exciting part of this announcement is MoneyStream's
adoption of the MobileTrust CA service which will provide an added security
backbone to MoneyStream's offerings, so its customers can be assured that their
financial transactions are secure."

         MoneyStream, serving as a Registration Authority to MobileTrust, will
issue digital certificates using MobileTrust to authenticate e-business
transactions as well as to protect the integrity and privacy of payment
information exchanged online. MobileTrust is a digital certificate service that
enables service providers, such as MoneyStream, to deliver their transaction
processing solutions to a wide variety of platforms, including mobile devices.
