Business Editors/High-Tech Writers

MILL VALLEY, Calif.--(BUSINESS WIRE)--Mar. 1, 2000

USV Telemanagement, Inc. ("USVT"), a wholly owned subsidiary of USV Telemanagement Inc. (OTC BB:YDSLF), announced it has introduced a new national Synchronous Digital Subscriber Line (SDSL) service targeted to attract the customer bases of niche market distributors.

"Our new national SDSL service is specifically designed to appeal to the business customers of interconnect companies and other niche market distributors," said company President Mark Smith. "As it is simple and easy to sell, the product should also fill the demand of Exstream Data and other providers of Internet services."

"We estimate that we now have access to in excess of 100,000 prospective business customers through a combination of our interconnect distribution channel, Exstream Data, and Stellar Net," continued Smith.

"With SDSL being so new to the market it is highly probable that few of these potential customers have SDSL service today. As such, we hope to capture a measurable portion of their business.

"Moreover, when you factor in the value added services we can now provide through Exstream Data the opportunity may be multiplied commensurately. The prospects for company wide revenue growth are better than at any time in the past."
