ZixIt Selected by Yahoo! to Offer ZixMail to Corporate Yahoo! Enterprise Information Portal Solution Customers

DALLAS--(BUSINESS WIRE)--Aug. 14, 2001--

New Alliance with Corporate Yahoo! to Promote Secure Email

ZixIt Corporation (Nasdaq: ZIXI) announced today that it has reached an agreement with Yahoo!, Inc. (Nasdaq: YHOO), a leading global Internet communications, commerce, and media company, to offer the ZixMail(TM) secure email service with the Corporate Yahoo!(TM) (http://corporate.yahoo.com) portal offering. As part of the agreement, ZixMail will be promoted in connection with sales and presentations of the Corporate Yahoo! enterprise information portal solution. This agreement deepens ZixIt's reach into the corporate market with its ZixMail services.

"This alliance with ZixIt allows Corporate Yahoo! to extend a valuable secure email offering to our prospective and existing Global 2000 customers," said Jim Lewandowski, vice president of Yahoo! Business and Enterprise Services. "Companies realize their employees send sensitive corporate information via the Internet, and in order to protect their information assets, increased security is warranted. In addition, ZixMail's certified receipts provide proof of delivery when a message is opened. Both are meaningful selling points with the corporate market."

As a plug-in for Microsoft Outlook(R) and Lotus Notes(R), ZixMail seamlessly integrates into business email solutions. ZixMail improves Internet communications security beyond existing firewalls, serving as a natural extension to a company's corporate security policy. ZixMail uses the most powerful encryption technology available to prevent unintended recipients from opening a message, and Corporate Yahoo! customers who purchase the ZixMail feature can send secure, encrypted messages to any email address worldwide, including non-ZixMail users.

"Like our partnerships with Fujitsu Limited/AlphaOmega Soft Co., Ltd. in Japan, and IT Factory Inc. and PC Guardian in the United States, the Yahoo! relationship is designed to increase our market exposure and add to our sales pipeline -- and ultimately to our bottom line," said Steve Gersten, senior vice president of sales and marketing for ZixIt. "We currently are working with Yahoo! in several areas to offer ZixIt's products and increase sales with both their existing and potential corporate customers, increasing the value of this partnership initially created in August 2000."

Corporate Yahoo! is a customized enterprise information portal solution based on the widely used My Yahoo!(http://my.yahoo.com/) interface. Enterprise customers licensing Corporate Yahoo! can easily integrate proprietary corporate content and applications with access to Yahoo!'s personalized Internet content and services behind existing firewalls. Corporate Yahoo! is a global solution that leverages Yahoo!'s position as the No. 1 most visited property at work, according to Nielsen//NetRatings' latest rankings, as well as an existing platform across 24 world properties and 12 languages.
