- the opening of new offices in Milan and Rome, Italy and Amsterdam, The Netherlands to support the Company's rapidly growing customer and partner base in Europe;

- the release of Transformation Server 6.0, which includes improved SQL Server support, support for multi-byte character sets including traditional Chinese, simplified Chinese, Korean and Japanese, monitoring enhancements and a new intuitive graphical user interface which makes it easier to manage Transformation Server.
