PEBBLE BEACH, Calif. -- Arron Oberholser and Mike Weir will share this week's AstraZeneca Charity Challenge title as they are tied for the lead entering the final round of the AT&T Pebble Beach National Pro-Am. The AstraZeneca Charity Challenge, formerly known as the CRESTOR® Charity Challenge, is a season-long competition that recognizes and rewards the tournament leader entering the final round at 35 PGA TOUR events. Through the sponsorship, AstraZeneca will donate $3.5 million this year to designated health care charities and will have donated a three-year total of $9.7 million by the conclusion of the 2006 PGA TOUR season.

AstraZeneca produces a wide range of products that make significant contributions to treatment options and patient care including CRESTOR, NEXIUM, SEROQUEL, ARIMIDEX, and PULMICORT RESPULES. Through this year's sponsorship, as part of its commitment to patient health and well being, AstraZeneca will also designate health care related charities across therapeutic areas as recipients at the 35 PGA TOUR events throughout the year.

For the performance by Oberholser and Weir, AstraZeneca will donate $100,000 to NAMI (National Alliance on Mental Illness) on behalf of the two players and the AT&T Pebble Beach National Pro-Am. The donation will help support NAMI's expansion of its successful Peer-to-Peer Recovery Education Course, which is a nine-week education course led by peer mentors, who themselves have achieved recovery from mental illness. Using the experience of the peer mentors, the Peer-to-Peer Recovery Education Course encourages wellness and recovery. The program will be available in 15 California counties, including Santa Clara, San Mateo and San Luis Obispo.

"The Peer-to-Peer Recovery Education Course plays an important role in our communities because it's a program that reinforces the fact that mental illnesses are very treatable and that recovery is very possible," said Kathryn Cohan McNulty, Director of Consumer Education Programs for the NAMI Education, Training and Peer Support Center. "We are grateful for the generous and continued support from AstraZeneca in advancing the expansion of the program. NAMI is thrilled that its Peer-to-Peer Recovery Education Course is now reaching and providing support to so many people who are in need of help."

"AstraZeneca's partnership with the PGA TOUR is an integral part of our mission of giving back in local communities throughout America," said Tony Zook, CEO, AstraZeneca U.S. "The AstraZeneca Charity Challenge offers a unique platform for providing important disease awareness, health information and education to make a difference in the lives of patients and consumers everyday."
