Open Text Announces IDEXX Laboratories Choice of Livelink To Manage Content

IDEXX Selects Livelink to Manage Information and Document Collaboration for Compliance

Chicago, IL. - 2004-04-13 - Open Text Corporation (NASDAQ: OTEX, TSX: OTC), provider of Livelink®, the leading collaboration and content management software for the global enterprise, announced today that IDEXX Laboratories, Inc. (NASDAQ: IDXX), a worldwide leader in the development and commercialization of innovative products and services for veterinary, food and water applications, has selected Livelink to manage collaboration on manufacturing and other critical process documents.

IDEXX adopted Livelink as its enterprise standard for document management, and to electronically manage changes to complex regulated documents, such as standard operating procedures, as well as other content. Livelink s controls and features for compliance with the U.S. Food and Drug Administration s (FDA) 21 CFR Part 11 rules for electronic signatures were significant factors in IDEXX s evaluation.

"Livelink provides an easy-to-access central repository for all of our quality system documents, and the system and controls needed for regulatory compliance," said David SeeHusen, Change Control Manager at IDEXX. "It also provides the controls and workflows we need to automate our processes and make working with these documents much easier."

"Most life sciences companies are wrestling with the challenge of managing information. It directly affects how efficiently they can operate and whether they can comply with industry regulations," said Martin Sumner-Smith, Vice President of Pharmaceutical Solutions at Open Text. "IDEXX has chosen a solution that will improve access to information and speed processes, while at the same time improving controls for compliance. It s a best-of-both-worlds' scenario."
