Open Text Completes Vignette Acquisition

    Open Text Will Continue to Support Vignette Products to Meet the Full
    Range of Web Content Management Needs

WATERLOO, ON, July 21 /PRNewswire-FirstCall/ - Open Text(TM) Corporation ( OTEX, TSX: OTC), a global leader in Enterprise Content Management (ECM), today announced that it has completed the acquisition of all of the issued and outstanding shares of Vignette Corporation ( VIGN). The acquisition has now received approval by Vignette's stockholders.

With its acquisition of Vignette now complete, Open Text said today that it is laying the strategic groundwork that will further its position as the independent leader in ECM, with a comprehensive portfolio of Web solutions to meet the broad range of market requirements.

Open Text will continue to support Vignette's products and installed base, including users of previous versions of Vignette Content Management, as well as Open Text's existing Web Solutions products. The combined product line will provide users with a full set of feature options, from an easy-to-use, fast-to-deploy web publishing application, to a fully integrated, enterprise-class e-business platform for large-scale deployments.

"The new demands of social and digital media, and fast-growing user expectations for more personalized Web interactions are placing enormous pressures on customers to keep up," said John Shackleton, President and Chief Executive Officer of Open Text. "This is an important area of innovation for us going forward as we expand our ECM portfolio - Vignette will play a key role in this strategy.

"We are making a strong commitment of support to our WCM customers and, at the same time, taking advantage of an opportunity to broaden our WCM capabilities to address a much wider range of needs in the market. Vignette expands our capabilities to meet the evolving needs of organizations to deliver compelling, interactive sites that drive e-business, customer loyalty and lead generation. We gain important capabilities that expand our leadership in WCM and complement our current range of products in this space."

According to Shackleton, Open Text also sees opportunities to leverage other key components of Vignette's product portfolio within the Open Text ECM Suite. Open Text will announce more details on product strategy in the weeks ahead, and will roll out a detailed product roadmap to include Vignette products at its annual Content World 2009 Conference, in October (http://www.opentext.com/contentworld/2009)

In addition to technology and expanded market leadership, Open Text gains other benefits from the deal: Open Text adds Vignette's experienced WCM professionals to the Open Text team, and Vignette supplements Open Text's global reach and already strong presence in key markets worldwide.

On the Vignette side, Vignette customers will benefit from Open Text's expanded ECM solutions portfolio, Open Text's strategic partnerships and integrations with major enterprise players such as SAP, Oracle and Microsoft, and the support of the world's largest independent ECM solutions provider.
