SDL Acquires Leading Media Asset Management Company

Calamares Acquisition Underscores SDL's Vision for the Future of Customer Engagement

MAIDENHEAD, England, May 4, 2011 - SDL (www.sdl.com/) plc (LSE: SDL; "SDL"), the leading provider
of Global Information Management solutions, today announced the acquisition
of Calamares, an internationally recognized cloud-based platform that allows
enterprises to centrally compose, enrich, publish and distribute video and
other rich-media assets. Calamares supports all media platforms, systems and
devices - from the Web and mobile to Internet Protocol television (IPTV) and
social media platforms. The gross assets being acquired are less than 5% of
SDL's gross assets.

With the acquisition of Calamares, SDL extends its customer engagement
offering to include video and rich media management. The Calamares media
management and enrichment solution will be fully and seamlessly integrated
into SDL's Global Information Management solutions, starting with the SDL
Tridion Web Content Management (WCM) Platform. By integrating the Calamares
media platform with the award winning SDL Tridion Web Content Management
solution, the state-of- the-art platform not only enables SDL customers to
easily produce and distribute video and rich content, but it also greatly
enhances customer engagements, marketing efforts, overall service, customer
satisfaction and new revenue opportunities.

Calamares currently enables a broad and diverse group of customers,
including Mitsubishi Motors Europe, Rabobank International and the Dutch
Ministry of Foreign Affairs.

John Hunter, CEO of SDL plc said, "We have seen significant demand for
solutions that enable the production, enrichment and monetization of video
and rich content. The Calamares acquisition represents another step in the
execution of SDL's strategy and commitment to deliver best-of-breed
solutions. We continue to enable and empower global enterprises with complex
content management, brand management, targeting, profiling, personalization,
multilingual, multi-cultural and multi-channel customer engagement and
services requirements."

Mark Lancaster, Executive Chairman of SDL plc commented, "We consider
multimedia graphical and video-based asset creation and management to be a
key need for businesses as they evolve the engagement with their customers in
the next 3-5 years."

Calamares was recently recognized by Gartner in its February 2011, 'Video
Content Management and Delivery MarketScope' report. According to Gartner,
"Surveys of organizations indicate that they believe their use of live and
on-demand video will increase by greater than 40% during the next few years."

Wouter Maagdenberg, CEO of Calamares, added, "Calamares has been very
successful delivering our solutions through a Software as a Service (SaaS)
model or direct licensing. Now as part of the SDL family, we will be able to
accelerate the development and expansion of our media management platform for
the WCM industry, while at the same time leveraging SDL's global reach and
market strength."
