Diversinet Corp. (NASDAQ:DVNT)(CDN:DVNT.)

Agreement Provides Paradigm4 with Leading Security

Technology for Public Safety and Healthcare Applications

Diversinet Corp. (NASDAQ:DVNT)(CDN:DVNT.), a provider of security solutions for wireless m-commerce applications, today announced a licensing and distribution rights agreement with Paradigm4, a wireless data solutions provider, to re-sell Diversinet's Passport Certificate Server 3.0(TM) and Passport Authorization Server 2.0(TM) products for integration into the Paradigm4's Wireless DataNet architecture.

The Paradigm4 Wireless DataNet links enterprise customers, carriers and application providers through direct frame-relay links, and routers provided by Paradigm4 that are located on their premises. These connections are configured with varying levels of redundancy, based on each entity's requirements, to minimize the likelihood that network failures will cause service interruptions. Paradigm4 provides alternate routing paths for data flowing between each carrier, application provider and enterprise customer. As a result, the network provides an integrated system for wireless data exchange among enterprise customers, wireless carriers and application providers.

The agreement will extend an end-to-end security standard to Paradigm4's capabilities in providing wireless data solutions to its customers. Both current and new Paradigm4 customers will have access to a full complement of wireless e-commerce security options, including the ability to use digital certificates for authentication, digital signatures for non-repudiation and digital permits for extending highly granular permissions. In addition to the licensing of Diversinet products, Paradigm4 will provide a managed certificate authentication service to those customers that prefer to outsource this function. Paradigm4 also intends to re-sell the Diversinet Certificate Server directly to customers that choose to manage the CA (Certification Authority) function themselves.

By including these secured wireless applications, Paradigm4 expects to strengthen its position in the implementation of wireless data solutions. "We fully understand the need to provide customers with the option of using a high level of security in their wireless e-commerce applications, and the agreement with Diversinet allows us to make that offer to customers today," said Bruce Boisture, President and CEO of Paradigm4.

Nagy Moustafa, President and CEO of Diversinet, added "Paradigm4 offers a complete solution for wireless data applications, and we believe they represent a significant channel opportunity for our products into new vertical markets such as healthcare and public safety. We look forward to working closely with them in developing the service and rolling it out to their customers."
