Dear valued MySQL customer,

Today, MySQL proudly joins forces with Sun Microsystems, the leading provider of platforms for the Web economy and the largest commercial open source contributor. We thank you — our customers, developers and community members — for your trust and continued support. Our commitment to you is that MySQL will continue to be a leader in the open source community and now, as a part of Sun, we will provide a new level of innovation, service and support.

Now that MySQL is a part of Sun, you may be asking, "What happens now?".

Simply put, it's business as usual, only better. You can continue to take advantage of MySQL's database with your existing hardware, operating system, and programming language of choice. But now you can leverage MySQL's and Sun's joint ability to provide you a complete suite of support options that enable you to rapidly build and deploy efficient, effective and secure applications and services. You can enjoy your total cost of ownership saving and benefit from our expanding roadmap and rates of innovation.

Interacting with MySQL will also be the same:

• Mysql.com will be your primary source of information on all things MySQL.
• The MySQL Customer Center will continue to provide you with access to the software and services you need to maintain and grow your MySQL applications. You can access the Customer Center from mysql.com through the "Customer Login" tab at the top of our home page.
• You can contact your MySQL sales and service representatives as before.
• You can learn from the leading MySQL experts at the annual MySQL Conference & Expo, April 14-18 in Santa Clara, California: www.mysqlconf.com.

The timeline for Sun and MySQL to fully join forces globally will span over the next few months to satisfy relevant country legal requirements. During this time period, Sun and MySQL will continue to meet your needs as a valued customer. We will continue to keep you updated and informed, and we intend to:

• Honor agreements made with customers and partners.
• Fully support the same popular platforms and languages that we support today.
• Work with the Free and Open Source software communities in an architecture of participation.
• Improve the MySQL database with Sun's global services capabilities and complementary product line-up to deliver even more powerful solutions for the online world, global enterprises, Telecommunications industry and the growing MySQL ISV and OEM partner community.
• Innovate by integrating MySQL software and services with Sun hardware and software — and other leading solutions.

We value your opinion and encourage your feedback. You can send your thoughts directly to us at marten@mysql.com. Please let us know if we can quote you publicly on your input and we look forward to receiving your comments!

Finally, we thank you for relying on MySQL and Sun as your trusted technology provider. We look forward to continuing to help you achieve and exceed your business goals for many years to come.

Sincerely,
