AdSubtract.com's Ad-Blocking Software to Ship with Zoom Modems
Industry's Hottest Ad-Blocking Software Bundled with Leading Provider of Data Communications Products

Braintree, Mass. - March 20, 2000 -- AdSubtract.com LLC, developer of Internet ad and cookie blocking software, and Zoom Telephonics, Inc. (NASDAQ: ZOOM) today announced an alliance that provides Zoom customers with instant access to AdSubtract software. Zoom has bundled AdSubtract's award-winning SE edition software with select Zoom and Hayes 56K modems, as well as with Zoom Air™ wireless LAN products. In addition, current owners of Zoom and Hayes products can also download the AdSubtract.com SE software on Zoom's web site at www.zoom.com.

The agreement between the two companies allows users to easily and efficiently block cookies and web banners to combat online user profiling and make web browsing faster and more pleasant.

Zoom designs, produces and markets a broad range of advanced communication products under the Zoom and Hayes brand names. Zoom products are sold in over 5,000 retail locations worldwide. Together AdSubtract.com and Zoom will collectively provide thousand of consumers with fast Internet access and ad-free surfing.

"Partnering with AdSubtract.com allows our customers to speed up their Web surfing," said Terry Manning, Zoom Vice-President of Sales and Marketing. "In addition, AdSubtract SE lets our customers enjoy enhanced online privacy on the Internet."

Online privacy concerns are escalating, as more people become aware of how easily personal data can be cross-referenced with presumably anonymous cookie data, to create extensive profiles of their online and offline activities. Online privacy has recently garnered the government's attention, and the FTC is currently reviewing what information is being gathered and if such information should be publicly accessible, as are credit reports.

"AdSubtract's partnership with Zoom provides new Zoom and Hayes users, as well as the huge installed base of existing customers, with a powerful weapon to defend their online privacy, and highlights the advantage of having access to an ad-free, clutter-free Web," said Ed English, President and CEO of AdSubract.com. "By harnessing the power of AdSubtract, Zoom's customers can protect their privacy and significantly enhance their Internet experience. Zoom has a long-standing reputation for providing cutting-edge solutions that improve their products' performance and make them easier to use. AdSubtract is pleased to be able to contribute to that tradition."
