Cauley & Geller, LLP Announces Class Action Lawsuit Against Visual Networks, Inc. Seeking Damages On Behalf of Shareholders.

Business Editors

BOCA RATON, Fla.--(BUSINESS WIRE)--July 20, 2000

The Law Firm of Cauley & Geller, LLP announced today that it has filed a class action in the United States District Court for the District of Maryland on behalf of all individuals and institutional investors that purchased the common stock of Visual Networks, Inc. ("Visual Networks" or the "Company") (Nasdaq:VNWK) between February 7, 2000 and July 5, 2000, inclusive (the "Class Period").

The complaint charges that the Company and certain of its officers and directors violated the federal securities laws by providing materially false and misleading information concerning, among other things, Visual Networks' acquisition and integration of Avesta Technologies Inc. ("Avesta") and the effects thereof on Visual Networks' operating results, including but not limited to its revenues, sales and earnings.

Specifically, the Complaint alleges that the defendants misrepresented that the integration of Avesta would be completed within three to four months, would create synergies of $5-12 million and lead to 50% increases in revenues for 2000 and 2001. Moreover, when the purported benefits of the acquisition failed to materialize during the initial phases after the transaction closed, the defendants failed to inform the investing public as such. In fact, when information relating to the adverse effects of the transaction started to emerge, the defendants made a series of affirmative misrepresentations to allay these concerns. Shortly thereafter however, the market's concerns proved accurate and the defendants were forced to disclose revenue and earnings shortfalls which they explained were the result of difficulties encountered in integrating Avesta.

As a result of these false and misleading statements the Company's stock traded at artificially inflated prices during the class period. When the truth about the Company was revealed, the price of the stock dropped significantly.
