Business Commentary and Third Quarter Outlook
Michael R. Gorsage, president and CEO, stated, “We continue to make progress in our company’s transformation. Last month, we announced, among other initiatives, our decision to realign our service offerings, rebalance our staffing, and exit low-margin staff augmentation projects. We are concentrating on our three high-potential competencies of enterprise application services, customer relationship management, and business technology. A number of trends emerged during the past quarter, indicating we are headed in the right direction. Our client portfolio has diversified as we gained a number of important new clients in new practices such as healthcare and financial services. We will remain focused on growth in our key areas — manufacturing, healthcare, consumer & retail, and financial services — where we see significant opportunities and a growing pipeline.”

Third Quarter 2005 Expectations
The Company is forecasting revenues before reimbursements for the third quarter of 2005 to be in the range of $9.0 million to $10.0 million. The Company expects third quarter results to range from a loss of approximately $1.5 million at the high end of the revenues range ($0.03 per share) to $2.5 million ($0.05 per share) at the low end. (Note that loss amounts are shown with no anticipated tax benefit.) Depending on revenues and cash collections, the Company expects to end the third quarter with a cash balance of approximately $19.3 million to $20.3 million.

“I’m committed to improving TSC’s financial performance, and we are taking the steps to meet that objective,” Gorsage said. “We’ve made significant progress, yet we still have more work to do. We have reduced our cost structure, as evidenced by the actions we took during the second quarter, and we continue to look for every opportunity to drive costs down even further. I am confident these actions coupled with our focus on revenue generation will return the Company to predictable and sustainable growth.”
