Mark Logic to Hold Executive Publishing Seminar on the Agile Publishing Imperative

Market Wire, October, 2007

What:    Mark Logic® Corporation, provider of the industry's leading XML
         content server, today announced that it will hold an executive
         publishing seminar on Thursday, November 8, 2007, featuring David
         Worlock, chief research fellow of Outsell, Inc., and Howard
         Ratner, chief technology officer of Nature Publishing Group.

         "The Agile Publishing Imperative: Accelerate the Creation of
         Information Products," will include commentary on market trends
         and realities from leading market watcher and publishing guru,
         David Worlock. Outsell published its seminal report on agile
         publishing more than two years ago, challenging publishers to
         adopt agile development principles. David will share his
         perspective on how publishing companies have responded to this
         challenge and which segments have successfully adopted agile
         techniques. He will also make predictions of where the information
         industry is headed in the near future.

         The executive event will share an example of agile publishing at
         work at Nature Publishing Group. Nature, a consistent innovator in
         the industry, was one of the first to apply Web 2.0 techniques to
         the publishing process, deploying XML to modularize content for
         targeted reuse and delivery. This move has positioned Nature to
         accelerate the development process to launch new products within
         weeks in some cases. Howard Ratner, Nature's chief technology
         officer, will profile results and benefits of agile publishing and
         share lessons learned on people, processes, and technology.

         David and Howard will join for a panel discussion following their
         presentations.

Who:     David Worlock chairs Outsell's Europe-based Executive Leadership
         Councils, a member-service for CEOs and senior executives of media
         publishing and information-provider firms. A respected thought
         leader, he frequently speaks at industry conferences and advises
         clients worldwide.

         Howard Ratner is chief technology officer of Nature Publishing
         Group. Based in New York, Howard is in charge of US operations and
         has global responsibilities for Production and Manufacturing,
         Emerging Technologies, Web Development and Operations, and IT
         across all NPG products. He serves on the board of directors for
         CrossRef and CLOCKSS, leads CrossRef Web Services, and is a member
         of the CCC Publisher Advisory and the STM Future Lab committees.

         The event will be hosted by Mark Logic Corporation. Mark Logic is
         uniquely positioned to help publishers unlock the value of their
         content to drive agile publishing business models that speed the
         delivery of new information products.

When:    "The Agile Publishing Imperative: Accelerate the Creation of
         Information Products," will be held from 8:00 - 11:00 am on
         Thursday, November 8, 2007, at the Four Seasons Hotel, 57 East
