Business Editors and Telecommunications Writers

SAN ANTONIO--(BUSINESS WIRE)--Jan. 22, 2001

American TeleSource International Inc. (AMEX:AI) ("ATSI") announced today that ATSI and GlobalSCAPE have engaged the investment banking firm of Roth Capital Partners Inc. ("Roth"), one of the largest independent investment banking and brokerage firms on the West Coast.

Founded in 1984, Roth Capital Partners has raised $3 billion in 135 offerings over the past seven years. In 1999, Roth Capital Partners led more underwritings for issuers with market caps under $150 million than any other investment banking firm, outranking such firms as Merrill Lynch, PaineWebber, CIBC and Bear Stearns. Roth completed 20 public equity transactions in 1999 raising approximately $765 million, with an average transaction size of $38 million. In each of the last six years, Roth Capital Partners ranked in the top twenty nationally among investment banks in aftermarket performance according to CommScan EquiDesk.

Roth will serve as the exclusive financial advisor to GlobalSCAPE to assist management in evaluating Strategic Financing Alternatives, which may include the following:

-- A proposed public offering of GlobalSCAPE's common stock.

-- The possible acquisition of third parties by GlobalSCAPE.

-- The possible sale of all or a part of ATSI's ownership in GlobalSCAPE.

H. Douglas Saathoff, ATSI's Chief Financial Officer, stated, "We chose Roth because of their successful track record as a quality, full service investment banking firm. Both Roth and the Company will work toward achieving the complementary goals of funding GlobalSCAPE, and allowing ATSI to leverage off the value of its ownership in GlobalSCAPE. We will work toward solutions that provide the best valuation for both companies and their respective shareholders."

Tim Nicolaou, GlobalSCAPE's Chief Executive Officer, stated, "Engaging Roth is an important step to support our strategic initiatives to broaden markets for CuteFTP, targeting digital media applications; to advance CuteMX technology in markets where peer-to-peer collaboration reduces the operating cost for e-commerce sites that handle massive amounts of information; and to build critical mass, acquire market share, and broaden GlobalSCAPE's brand through strategic acquisitions."

Grant Garbers, Managing Director at Roth Capital Partners, stated, "We look forward to working closely with management in developing a financial strategy that will allow both ATSI and GlobalSCAPE to pursue their strategic objectives while at the same time enhance shareholder value."
