Hackensack, NJ and Mountain View, Ca. -- April 5, 2000 --- Net2Phone Inc. (NASDAQ: NTOP) and Netscape, a subsidiary of America Online, Inc. (NYSE: AOL), today announced that Net2Phone's award-winning PC software is now fully embedded into Netscape's new Netscape 6 (R) browser, providing Netscape 6 users with value-added low-cost voice services from their PCs. Netscape 6 Preview Release 1 was released today and is available for download at Netscape Netcenter. This integration is part of a multi-year agreement with Netscape to bundle Net2Phone's PC services throughout Netscape's properties.

Jim Martin, senior vice president and general manager of Netscape Netcenter, said, "This relationship distinguishes Netscape as the most complete Internet browser by adding the most natural form of communication today -- voice. Netscape has continuously provided its users with the highest level of quality with all of our services, and we believe Net2Phone's products will serve as a turn-key solution to consumers and businesses worldwide who want an enriched multimedia web experience."

Netscape has added a new button to its Personal Toolbar on the Netscape 6 browser, entitled "Net2Phone," enabling browser users to place calls from their multimedia PCs to any telephone or multimedia PC around the world.

"Now for the first time, Internet users around the world can make calls directly from their browser. A button on Netscape's personal toolbar is prime real estate for the Internet, and we are excited about the integration with Netscape's browser as well as throughout the Netcenter site," said Howie Balter, CEO of Net2Phone. "Through this integration, Net2Phone has become an integral part of the surfer's web experience, bringing the voice component of the web to all Internet users."

Net2Phone's PC services are also integrated throughout Netscape's Netcenter portal, enabling one-click dialing integration with Netscape's online directories and address books. Users can call anywhere within the U.S. for 1 cent per minute. International rates begin at 3.9 cents per minute. Fulfillment is now immediate since the integration of the browser eliminates the previous required download.

The powerful combination of Netscape 6, Net2Phone and the Netscape Netcenter portal will offer consumers and businesses a convenient and low cost way to keep in touch with friends, family and business associates. By incorporating Net2Phone into Netscape's suite of services, Web users with one phone line can place phone calls and surf the Web at the same time. In addition, because calls are placed directly through the Internet, consumers will realize substantial savings.

Netscape 6 Preview Release 1 is available today for public download on Netscape Netcenter. The new groundbreaking browser is small in size, leads the industry in standards compliance and can run across a wide variety of platforms from traditional PC desktops to new computing devices. Netscape 6 offers users unmatched convenience features, the ability to stay connected to important information and the flexibility to deeply customize the browser to fit their individual needs and personality.
