VONAGE BECOMES MDA TELETHON SPONSOR

TUCSON, Ariz., July 18, 2005 – Vonage, the broadband telephony company, has joined the national sponsor ranks of the MDA Jerry Lewis Labor Day Telethon.

A leader in the broadband phone industry, Vonage joins dozens of other national corporations, including Harley-Davidson, CITGO, Seven Up and Anheuser-Busch, having cause-related marketing programs that raise funds for the research and service programs of the Muscular Dystrophy Association.

Vonage will donate $30 to MDA for every new customer using the Internet to sign up for Vonage services from July through September via www.vonage.com/mda. Vonage provides subscribers with an Internet phone service allowing their standard telephones to be connected to their broadband connection via a telephone adapter. This provides unlimited local and long-distance calling for only $24.99 a month.

MDA National Chairman Jerry Lewis said, “Vonage is providing considerable savings to customers who make many long-distance and local calls and is also contributing importantly to MDA by raising funds for medical care and research. I encourage the public to learn more about this special Vonage promotion by visiting the Vonage banner ad on MDA’s Web site at www.mda.org.”

The Telethon will be broadcast Sept. 4-5, originating from The Beverly Hilton in Beverly Hills, Calif.

MDA is a voluntary health agency working to defeat more than 40 neuromuscular diseases through programs of worldwide research, comprehensive services and far-reaching professional and public health education.
