“We are pleased to report record quarterly revenues and net income. We experienced strong growth in our Technology Development, Civil, Toxicology and Mechanics and Materials practices,” commented President and CEO, Michael R. Gaulke. “During the quarter Technology Development delivered additional integrated robots and controllers to assist the U.S. Army in exploring caves and searching buildings. Our engineering field support teams in Iraq and Afghanistan have been supporting the Rapid Equipping Force in developing and deploying technologies to soldiers in the field. Additionally, we worked on the fourth phase of the Advanced Combat Uniform project, which included the prototyping of our proposed design for the next generation of soldier ensemble.”

Mr. Gaulke continued, “We continued our strategic focus in pursuit of a leadership position in health science consulting. During the quarter we continued to be involved in the scientific aspects of litigation involving alleged health hazards of asbestos in products, such as floor tiles, roofing materials, glues and brake pads. Additionally, the integration of our new Food and Chemicals practice, formerly Novigen Sciences which was acquired in May of 2002, continued to contribute to the growth of this segment of our business.”
