Consumers Experience "Like No Other"

John Mayer, Dido, Ari Hest to Perform in New York City's Bryant Park

Five For Fighting, Butch Walker To Give Lunchtime Concert In Union Square

This summer, concertgoers will be "carded" in a whole new way. Bank One [NYSE: ONE] and Sony Corporation of America today announced that recording artists John Mayer, Dido and Ari Hest will be performing a free concert that begins at 5:15 p.m. in New York City's Bryant Park Thursday, June 17, 2004. The concert will be the culmination of the Sony Card Entertainment and Technology Experience Like No Other, a two-day event presented by Bank One and the Sony Card.

The Experience will showcase what the Sony Card can provide cardmembers - an exclusive all-access pass into a total experience that includes the latest Sony entertainment and technology innovations.

The Experience will commence Wednesday, June 16 and provide consumers the opportunity to explore the "Live Better, Go Digital" interactive tour sponsored by Sony Electronics and Intel, which features VAIO® PCs that go far beyond computing; as well as The Tech Pit - a multimedia exhibit filled with WEGA® TVs and DVD Dream® Systems. Visitors can also sample a variety of Walkman® digital music players and enjoy downloads powered by the Sony Connect music store, or capture the excitement of concerts and movies in the Sony XPLOD® demo car. They can even create their own entertainment using the latest Cyber-shot® digital cameras and Sony Ericsson mobile phones.

The Experience will continue June 17 and include a free lunchtime concert at noon in New York's Union Square. This concert will feature Five For Fighting, best known for their Grammy nominated anthem "Superman," as well as their new hit "100 Years" from their current album "The Battle For Everything," and rock & roll, singer-songwriter Butch Walker, whose upcoming album, "Letters," will be released this summer.

Consumers who apply for the Sony CardSM by visiting www.sonycardexperience.com from June 4-17 or by attending the Experience event June 16-17 at Union Square, will receive access to a premiere seating section for the June 17 concert in Bryant Park. Current Sony Cardmembers will also receive special invitations to attend the concert.

Aware/Columbia/Sony Grammy-winning, singer-songwriter and guitarist John Mayer is currently supporting his platinum sophomore disc, "Heavier Things," which debuted at number one on the Billboard album charts. Mayer will return to the road this summer on a 42-date headlining tour that kicks off July 2. Platinum-selling artist Dido's most recent album "Life For Rent" set a record for first week sales by a female artist. They will each play a full set in Bryant Park. Ari Hest, whose Columbia Records debut "Someone to Tell" will be released late this summer, will open the show.

"The Sony Card provides a gateway into the world of entertainment and technology," said John Briesch, president, Sony Card Marketing and Services Company. "This special event underscores our commitment to making the Sony Card as exciting and innovative as our products."

"We began working with Sony to create a 'must have' Visa card for our cardmembers that goes beyond rewards," said Carter Franke, chief marketing officer for Bank One's card services division. "The power of the Sony brand, combined with Bank One's co-branding leadership, allows us to deliver innovative rewards to consumers in a way that more naturally fits their lifestyle."
