Announcement of Principals of RWDI Group Inc.

I am pleased to announce that in recognition of their outstanding achievements and consistent performance, Paul Freathy, Stoyan Stoyanoff and Jiming Xie have been made Principals of RWDI Group Inc., effective August 1, 2006.

Paul was already a shareholder of RWDI Anemos Ltd. where he has been Managing Director since it was formed in September 2004. With this appointment, he will exchange his ownership in RWDI Anemos for corresponding ownership in RWDI Group Inc. Paul ran his own successful wind consulting firm, PF Consultants, for a number of years and then formed Anemos Associates Ltd. (Anemos) with Nicholas Cook. Anemos developed an excellent reputation and worked with many well known U.K. clients. Two years later, Paul and Nicholas became members of the RWDI team when Anemos and RWDI joined forces to form RWDI Anemos Ltd.

Stoyan joined RWDI in 1993 as a Senior Specialist. Following that, he became a Project Director and Associate. His project involvement with the company has focussed on the field of aerodynamics, aeroelasticity, structural dynamic, finite elements, and wind effects on various types of engineering structures (bridges, stadiums, buildings, towers, transmission lines, space vehicles). As Project Director, he coordinates and supervises aerodynamic and structural dynamic studies. In addition, Stoyan has been a leader in developing advanced analytical methods for the wind response of long span bridges.

Jiming joined RWDI in 1989 as a Project Engineer and was subsequently appointed Project Director and Associate. His primary responsibility is conducting wind engineering studies for large structures, including bridges, buildings, stadiums, etc. as well as being responsible for quality assurance and technical development of the company’s wind engineering services. Jiming has been responsible for the development of several cutting edge methods for determining design wind loads and responses of complex high-rise structures.

On behalf of the management of RWDI, I would like to take this opportunity to personally congratulate Paul, Stoyan and Jiming and welcome them as shareholders of RWDI Group Inc.

Congratulations!

Peter Irwin
