InterVideo Acquisition

Message from Dave Dobson and Randy Eisenbach

A Message from Corel to the InterVideo & Ulead Teams

On behalf of Corel’s executive team and our employees around the world, I am pleased to extend a personal greeting to everyone on the InterVideo and Ulead teams. We are very excited at the prospect of further strengthening relationships with partners and customers by bringing together the products, knowledge and expertise of three established, innovative, and successful companies. Together, Corel, InterVideo and Ulead will offer the industry’s broadest portfolio of digital media software for image creation and editing, photo sharing, video editing, and DVD creation and playback. By combining the capabilities, insights and perspectives of our three companies, we believe we will be uniquely positioned to address the growing market demand for digital media and content.

Last week, many of you had the opportunity to meet with Corel’s Chief Operating Officer, Randy Eisenbach. Randy and I are committed to ensuring that the integration planning process is highly collaborative. We have a great deal to learn from the InterVideo and Ulead teams and we will be meeting with many of you over the coming weeks in order to better understand the important aspects of your businesses.

Throughout the evaluation process, prior to the acquisition being announced, it became very clear to us that InterVideo’s and Ulead’s strengths were highly complementary to Corel’s. With talented employees, world-class technologies and demonstrated leadership in engineering and development , InterVideo and Ulead will enable Corel to further extend our product portfolio and broaden the technological base from which we do business. In turn, Corel’s award-winning product lines will provide your customers with an expanded range of offerings from a single trusted source. In addition the acquisition will broaden the global reach of our companies’ combined products. Corel will benefit from InterVideo’s and Ulead’s partnerships and geographic presence in Asia Pacific, as together we expand our footprint across Asia Pacific, the Americas and Europe.

Next Steps

We recognize that some of you may have questions about what the acquisition will mean for you both personally and professionally. These are reasonable questions however we are still too early in the planning process to provide these answers. Over the next several weeks, we will be actively engaged in a “discovery process” where Corel employees will be working closely with many of you to ensure we have a thorough understanding of all aspects of the InterVideo and Ulead businesses. We will be spending a lot of our time listening, and working collaboratively with you so that, together, we make the best decisions to support the long term success of our combined new company.

To facilitate the decision making process, we will be forming an integration team comprised of representatives from Corel, InterVideo and Ulead. This team’s mandate will be to work together to build a successful integration plan that fully leverages the knowledge, talents and expertise of each organization. The integration team will use the same collaborative approach to guide all decision making. We expect the discovery process to run until the end of of October with proposed integration plans to be completed sometime before the end of November.

Until the acquisition officially closes, which we expect will occur sometime towards the end of the fourth quarter 2006, Corel and InterVideo must continue to operate as separate companies. As a result, we will be somewhat limited in what we can communicate, however, between Corel and your management team, we will ensure that we provide regular updates to keep you well informed of our progress.

While we have much to accomplish together over the next several weeks and months, we are encouraged by the new opportunities this powerful combination will create for our partners, customers and our newly combined company. We look forward to working with all of you.

Sincerely,

David C. Dobson

Corel CEO
