Under Armour® Announces Details of All-America Lacrosse Classic, June 16th-18th at Towson UniversityBALTIMORE, April 27, 2006 - Under Armour®, a leading developer, marketer and distributor of branded performance products, announced today the details surrounding the first annual Under Armour All-America Lacrosse Classic, taking place June 16th-18th at Towson University in Baltimore, Maryland. Underscoring Under Armour's continued commitment to the team sport of lacrosse, the company has partnered with Corrigan Sports Enterprises (CSE) to create a national event that recognizes the top high school players in lacrosse. Tickets are available through Ticketmaster at 410-547-SEAT, and more details are available at www.underarmourlacrosse.com. "The classic is something we wanted to take to a national level while basing its inaugural game here in Baltimore, the home of Under Armour and lacrosse," commented Kevin Plank, Chairman, CEO and President of Under Armour. "From the start, Under Armour has been committed to providing players with a performance advantage on the field, and lacrosse has been a big part of our branding initiatives. We're excited to be a part of the sport's rapid growth across the country."

The custom uniforms unveiled today feature Under Armour's technically advanced moisture transport system, which wicks moisture away from the skin, enabling athletes to stay cool, dry, light and comfortable. Uniforms will feature the new All-America Game logos for boys and girls.

Nominations for high school senior top lacrosse talent are being accepted on-line through April 30th at www.underarmourlacrosse.com. Inside Lacrosse magazine has established a selection committee to uncover top talent - both male and female - from across the country. The All-America Games will host the nation's top boys and girls lacrosse players, both high school seniors and underclassmen, in a weekend event designed to underscore the exceptional talent of these athletes on the playing field.

Under Armour also announced that legendary player and coach, Gary Gait, and lauded former Georgetown Hoyas coach, Kim Simons, will chair the event. Gait, recent inductee into the National Lacrosse League Hall of Fame and widely considered one of the most accomplished players in the sport of lacrosse, and Simons, former coach of the nationally ranked Georgetown Hoyas, will preside over the games as well as oversee the coaching staff, which includes athletic professionals from the leading lacrosse powerhouse schools from across the nation.

The June 16th-18th event will include clinics and scrimmages, culminating in a series of competitive games on the field. The unprecedented live telecast by ESPNU, the 24-hour college sports network, of the senior boys All-America Games will highlight the close of the Games, which takes place on June 18th at 7:00 p.m. The final day of the event will also feature the Under Armour Lacrosse Experience, which includes interactive games, family fun, a tailgating party, and a tent sale.

STX will provide players with sticks, goggles and gloves, with helmets provided by Cascade.
