Contigo i2i Chosen by ZD Events as a Vehicle for New Internet-Based Service Offerings.

LAS VEGAS--(BUSINESS WIRE)--Nov. 15, 1999--

ZDEvents to provide Web-based educational seminars and conference

programs using Contigo's new i2i Internet Conferencing system

Contigo(TM) Software Inc. (www.contigo.com), the pioneer and leading provider of Web-based conferencing products for sales, marketing and training applications, and ZD Events, the leading producer of information technology tradeshows and conferences, Monday announced that the two companies have entered into a strategic relationship to enhance the event experience.

This alliance will enable ZD Events to host interactive, online educational programs as part of their overall strategy of providing a complete virtual forum for learning, evaluating and comparing the solutions that are driving the new Internet economy.

ZD Events will use Contigo's i2i(TM) Internet Conferencing System in this new endeavor to augment its success in producing traditional face-to-face trade shows and conferences with the power and reach of the Internet.

The first two products resulting from the ZD Events/Contigo relationship are: COMDEX University - an on-going, comprehensive curriculum of online educational courses for technology decision makers; and the Vendor Online Seminar Program - an opportunity for vendors to develop virtual seminars to be transmitted on the ZD Events website.

"Keeping up-to-speed is critical. COMDEX and ZD Events' other brands have always focused on providing the best in on-going technology education and information," said Al DiGuido, executive vice president for ZD Events.

"Leveraging the power of the Web is a natural extension to our face-to-face trade shows and seminars, and who better to do it with than a Web communication trailblazer like Contigo Software. Contigo's drive, innovation and commitment to advancing Internet-based communication made up our minds - we're extremely excited to be working with them in this endeavor."

"This is a great opportunity for both ZD Events and Contigo," said Bob Brown, Contigo's president and chief operating officer. "ZD Events is the premier technology trade show and seminar producer, and we know that by combining their event production and management talents with our state-of-the-art Web-based conferencing technology, this project cannot help but be a huge success."

Blending ZD Events' experience as the world's premier platform for face-to-face interaction with Contigo's Internet Conferencing expertise and innovative patented technology will optimize the interaction between buyers and sellers for business, commerce, education and direct networking.

Contigo will be demonstrating the technology behind the new seminar products, i2i, at COMDEX/Fall in Las Vegas, Nov. 15-19 in the .COMDEX Pavilion (No. L6055, Space No. SB11, Las Vegas Convention Center, South Hall).
