Business/Technology Editors

WALTHAM, Mass.--(BUSINESS WIRE)--May 6, 2002

Software Ensures Copyright Protection Against Unauthorized

Distribution of Electronic Education Materials; Caldera OpenLearning

Courseware with PageRecall Features Available Summer 2002

Authentica, Inc., the premier provider of digital rights management software for securing business intellectual property both within and beyond the corporate domain, today announced that Caldera International, Inc. (Nasdaq: CALD), the global leader in providing Linux and UNIX business solutions, has selected Authentica's PageRecall(TM) document security software. Caldera(R) will use PageRecall to protect against unauthorized reproduction and distribution of its OpenLearning(TM) Courseware that it provides digitally to its global network of partners and customers.

Caldera faced a common and growing problem in the training and services sector: preventing the piracy of its digital courseware offerings.

"Caldera had a classic problem that we see with companies that want to provide high-value digital content, but are rightfully concerned with the issues of misuse and illegal distribution," said Jim Hickey, vice president of marketing at Authentica(R). "With PageRecall, Caldera is able to leverage the speed, efficiency and flexibility of electronic distribution without the fear that those materials will be copied, misappropriated or otherwise used by someone who did not pay for them."

"Caldera has found that as demand for electronic distribution of our education content grows, we've needed to protect our intellectual property from being illegally copied, shared or printed," said David Acheson, director of Caldera Education Services at Caldera. "As we evaluated different solutions, we found that PageRecall would give us strict control over the distribution of our electronic information. We expect a quick return on our PageRecall investment because we will now receive compensation for our distributed materials."

PageRecall gives Caldera an easy-to-use solution for securely sharing valuable education content with partners and customers without surrendering the rights to control how this information is accessed and used after it has been distributed.

Unlike other approaches to content security, Authentica's software allows Caldera to:

-- recall or expire information at any time;

-- establish whether recipients have the right to share, print, or

copy information;

-- track the activity of information, including when and how often it is accessed and printed; and

-- change access or usage policies regardless of where copies of the information are located.

Caldera Education Services provides classroom instruction, access to on-line learning or other self-paced courseware designed to meet the demands of Linux and UNIX IT professionals. Caldera OpenLearning Courseware with PageRecall features will be available for purchase Summer 2002. Details will be available soon at http://www.caldera.com/education.

PageRecall is part of Authentica's suite of digital information security solutions, which also includes NetRecall(TM) for Web content and MailRecall(TM) for e-mail. As an integrated solution, Authentica's products are scalable, easy to use and simple for IT to deploy and administer across the enterprise.
