Plaxo for Mac 1.0 Now Available

World’s First “Smart Address Book” Comes to the Large and Growing Mac Community

MOUNTAIN VIEW, Calif.–May 11, 2006– Plaxo, Inc., creator of the smart
address book, today announced the immediate availability of Plaxo for Mac
version 1.0. As the most frequently requested capability from current and
would-be Plaxo members, the company launched a public beta of Plaxo for Mac
this past March. This new offering brings the world’s first smart address
book to the large and fast growing Mac community. Plaxo for Mac will be
especially welcomed by those who use a PC at work and a Mac at home and
want a single, always up-to-date set of contacts on both systems.

Plaxo provides members with a single, smart address book that can be used
virtually anywhere. The average person has several email and instant
messaging accounts and as a result, they also have contact information in
more than one location. Plaxo combines this separate information into one,
always updated address book that is accessible within all of the most
popular applications so that the same information is available everywhere.

With Plaxo for Mac, users of Mac OS X v10.3 “Panther” and Mac OS X v10.4
“Tiger” can enjoy the benefit of automatic synchronization between their
Mac OS X Address Book, Plaxo’s online service and a number of other popular
communication tools and services, including Microsoft Outlook and Outlook
Express, AIM, and Thunderbird. In addition, Plaxo members can enrich their
address book by importing contacts from their Netscape, Palm, Yahoo! Mail,
and Hotmail accounts.
