Mac Publishing, Covad and Netopia Launch the Premiere DSL Web site for Macintosh Users

SAN FRANCISCO, Calif., SANTA CLARA, Calif., and ALAMEDA, Calif. — January 4th, 2000 — Mac Publishing L.L.C., the premier source for Macintosh information, Covad Communications (NASDAQ: COVD), the leading national broadband services provider utilizing DSL technology, and Netopia, Inc. (NASDAQ: NTPA), a market leader in providing DSL Internet equipment and E-commerce Web platforms to small and medium-size businesses, today joined forces to launch the MacDSL Center Powered by Covad and Netopia (www.macdsl.netopia.com). This will be the premier DSL (Digital Subscriber Line) Web Site targeted at Apple Macintosh and iMac users, and promises to be a one stop shopping center for getting Mac users connected to the Internet at high speeds.

Featured on Mac Publishing's Web sites, including Macworld.com and MacWEEK.com, the Covad/Netopia MacDSL Center provides a wealth of information on DSL technology, specially tailored to the needs of Macintosh users. It also allows visitors to determine whether DSL is available at their address, and will put them in touch with local ISPs (Internet Service Providers) who offer Covad DSL service and Netopia DSL equipment. The Covad/Netopia MacDSL Center has an exclusive relationship with Mac Publishing, which will promote the Center to more than 2.5 million monthly visitors.

"We are very pleased to work with Covad and Netopia to bring DSL information and connectivity to the Macintosh community," said Colin Crawford, president and CEO of Mac Publishing. "Covad's nationwide DSL coverage and Netopia's rich-featured, easy-to-use DSL equipment will make it simple for Macintosh users to obtain high-speed DSL access to the Internet."

"We are excited to extend our successful relationship with Netopia by co-producing the Covad/Netopia MacDSL Center," added Rich Wong, vice president of marketing for Covad. "Its accessibility from the Mac Publishing Web sites should ensure that it will become the Web's leading venue for DSL information and online DSL ordering for Macintosh users."

The Covad/Netopia MacDSL Center aims to answer all the questions Macintosh users face when looking to purchase DSL service. These questions include:

— How can I connect a hybrid network of Macs and PCs to a DSL connection?

— How can I combine Appletalk and TCP/IP Macs on a DSL connection?

— How will DSL work with Apple's new Airport wireless products?

— How can DSL increase productivity for professionals, such as graphic designers, who typically work in Macintosh environments?

— How can I set up a Virtual Private Network using Macintosh computers and a DSL connection?

— What unique capabilities, such as support for QuickTime 4.0, do Netopia DSL products offer Macintosh users?

The Covad/Netopia MacDSL Center also aims to make ordering DSL as simple as possible:

— Visitors first fill out a pre-qualification form that allows Covad to determine whether DSL service is available at their address.

— If service is available, visitors are then taken to the ISP Spotlight page which provides a detailed list of ISPs and their DSL service offerings.

— Once they choose an ISP, visitors are taken to the Order Confirmation page where they can place their order for Covad DSL service and Netopia DSL equipment.

"The Covad/Netopia MacDSL Center will be the premier Web site exclusively dedicated to popularizing DSL technology among Macintosh users," said Michael Trupiano, senior vice president and general manager, Netopia Internet Equipment Division. "Netopia DSL equipment offers unique benefits to Macintosh users, including Appletalk routing, AURP tunneling, Localtalk to Ethernet routing and Quicktime 4.0 application gateway support."
