Business/Technology Editors

NEW YORK--(BUSINESS WIRE)--Jan. 17, 2001

ARS Networks Inc. (OTC BB: ARSN) whose first product is a state-of-the-art advance warning system for railway crossings, today announced that its wholly owned subsidiary, T&T Diesel Power Ltd., will change its fiscal year from July 31, 2001 to January 31, 2001 to correspond with ARS's fiscal year.

T&T's invoiced-to-date contracts of $562,881 and a backlog of close to $209,490 combine for a total of over $772,372 for the six months ending January 31, 2001. T&T remained on track to exceed its revenue projections of $1.4 million for fiscal year 2001. T&T will release new projections in February 2001 to coincide with its revised year-end.

Sydney Harland, president and chief executive officer of ARS, commented, "T&T has proven to be a valuable addition to ARS Networks. I am very pleased with its consistent performance and I am confident that it will continue to produce strong results to add to our bottom line and enhance shareholder value." Harland continued, "T&T has been a tremendous help in the packaging of ARS Networks' equipment and provides us with a bricks-and-mortar facility from which the Crosslogix(TM) organization can operate."

The purchase of T&T Diesel was ARS Networks' first step in implementing its strategy of acquiring profitable companies that can be integrated into its core business -- the design and marketing of safe, cost-effective, and reliable systems for the railway industry. T&T supplies auxiliary power generators to leaders in the telecommunications sector like Marconi, Bell Mobility and Rogers AT&T Wireless.

ARS Networks Inc. is a wireless communications technology company that designs, develops and commercializes safe, cost-effective, and reliable systems for the railway industry using patent-pending, remote sensing equipment. Its systems feature an open architecture platform that offers railways and their freight customers unrivalled abilities to address public safety at level crossings, track cargo, communicate with dispatchers and shorten delivery times. The Company's platform provides a portal for a multitude of applications in real-time data collection, processing, monitoring and information analysis tailored for the railway industry.

The ARS Crosslogix(TM) system, unlike current systems, can operate as a stand-alone, independent of local power. Conventional system suppliers often have to pull in power lines from as far as two miles away to support their systems, making installation of crossings both more expensive and more difficult.
