AIDS Walk New York Wins with Kintera Technology; 2005 Event Nets $2.3 Million in Donations Using Kintera Tools; Amount Is Three-Fold Increase Since 2002.

SAN DIEGO -- Before lacing up their walking shoes, nearly 7,000 of the 45,000 participants in the 20th Annual AIDS Walk New York logged on to raise a record-setting $2.3 million in online donations using fundraising tools provided by Kintera(R), Inc. (Nasdaq:KNTA), the leading provider of software as a service to the nonprofit sector. Approximately $6 million has been raised online by the organization since first utilizing Kintera's web-based technology in 2002, when event participants were initially offered personalized websites with linked email by AIDS Walk New York.

AIDS Walk New York -- the world's largest AIDS fundraising event -- is produced by the leading AIDS fundraising organization in the U.S., MZA Events, and benefits Gay Men's Health Crisis (GMHC).

Walk participants are offered tools to create personal and customizable websites within the main AIDS Walk New York site at www.aidswalk.net/newyork, based on the easy-to-use Friends Asking Friends(R) (FAF) service that allows users to send solicitation emails to friends and family.

For the 2005 AIDS Walk New York, fundraising results (as of May 31, 2005) included:

--45,000 participants helped raise $5.8 million, of which $2.3 million was donated online. This represents a 28 percent increase from online revenue compared to last year's event and a 244 percent increase since 2002.

--7,094 online participants sent a total of 195,685 FAF emails, raising a total of $2.4 million, online and offline. For each participant who sent FAF emails, the average raised was $338 with an average of 28 emails sent. This represents a 240 percent increase in the amount of money raised through FAF, and a 193 percent increase in the number of FAF emails sent, since 2002.

"We're extremely thrilled with the results we've achieved using Kintera's online fundraising tools," said Bill Brent, Chief Operating Officer at MZA Events. "Each year, more and more people are embracing the Internet, creating personalized websites and raising incredible amounts of money for our cause. Thanks to Kintera, we've raised a record amount this year in the fight against AIDS."

The Kintera Sphere(TM) software platform provides MZA Events with a unified system that includes event management, sophisticated email communications, registration services, secure and private online donation capabilities and advanced online solicitation and stewardship functionality. MZA Events and participants are able to know in real-time the total funds raised throughout the campaign.
