Open Source and Software Industry Experts Endorse Dual-License

as Good for Business -- Three Companies Show Average of 65%

Revenue Growth in 2003

Sleepycat Software, Trolltech AS and MySQL AB today jointly announced that 2003 software license revenues for the companies increased an average of 65 percent over the previous year, largely due to their use of the dual-license business model. This increase is 10 times the overall growth of U.S. IT industry spending in 2003, measured at only 6.4 percent, according to the U.S. Department of Commerce*.

Trolltech AS, MySQL AB and Sleepycat Software are strong examples of second-generation open source companies that have established growing, sustainable businesses based on open source software. Both the business model and the open source software license are gaining increasing support in the IT industry. The companies provide dual-license software to some of the largest customers in the world, including Cisco, Google, IBM, Motorola, Sharp Electronics and Yahoo!, among hundreds more.

"Dual-license companies combine the software quality and distribution benefits of an open source model with the software licensing revenue model of a traditional commercial software vendor," said Dan Kusnetzky, vice president for System Software Research at industry analyst firm IDC. "This appears to be a successful business model. It offers customers seeking a traditional packaged software model what they want in terms of documentation and ongoing support. For those seeking freely available software and the open source model of community development and support, they get what they want."

Second-Generation Companies

As second-generation open source vendors, MySQL AB, Sleepycat Software and Trolltech AS make the majority of their revenue from selling software licenses. This license-based business model offers higher margins than services-based businesses. Historically, most open source companies have tried to make money by selling services and support.

The guiding principle behind dual licensing is "quid pro quo," or a fair exchange. Under this model, vendors offer their products under both an open source license and a commercial license. This allows open source projects to use the software at no cost, which contributes to widespread use and testing of the software and the fast growth of a large installed user base. Companies redistributing the software as part of commercial products can also get the benefits of the open source software by purchasing a commercial license, which releases them from requirements to publish their source code. Commercially-licensed customers generate revenue for the open source vendors, which contributes to the rapid development of high-quality software.

"Dual-license products give customers who redistribute a choice in license terms," said Eben Moglen, professor of law at the Columbia University Law School and recognized as one of the world's leading experts on copyright law as applied to software. "Proprietary commercial licenses can offer customers fewer restrictions on inclusion in closed source products and enable open source software developers to grow strong businesses. This model is a win for the free software movement too, as it ensures that dual-licensed software products will be developed and supported by viable companies, and also remain available for free copying, modification and redistribution for the long-term."

CEOs Marten Mickos of MySQL AB, Mike Olson of Sleepycat Software and Haavard Nord of Trolltech AS, along with Bob Bickel of JBoss, speak today at the Open Source Business Conference on a panel that covers the best practices and guiding principles of the dual license business model and investigates the benefits and risks inherent in the model. The panel runs from 3:30pm to 4:15pm at the Westin St. Francis Hotel in San Francisco, California.

The three CEOs will discuss from the benefits of dual-licensed products and how customers gain all the advantages of open source software, such as:

-- An established community of open source developers sharing

code;

-- Faster time to market with higher software quality,

reliability and stability; and

-- Freedom from vendor lock-in.

In addition, customers gain all of the benefits traditionally associated with commercial software, including:

-- A paid, full-time, dedicated development team, providing

continuity, a roadmap of upgrades and professional

documentation;

-- Enterprise-level, production and developer support available

24/7/365; and

-- Confidence that the vendor has full rights and/or ownership of

all intellectual property in the software.
