The arena, which now will be known as Jobing.com Arena, had been without a corporate sponsor since it opened in December 2003. Jobing.com, a Phoenix-based online employment service, will pay US$2.5 million per year in the 10-year agreement, the team said Wednesday at a news conference.

The arena, also the home of an indoor lacrosse team and numerous concerts and trade shows, is next door to the Arizona Cardinals' new stadium in suburban west Phoenix. The Cardinals recently sold naming rights to the stadium to the University of Phoenix for $154.5 million over a 20-year span.

Founded in 1999, Jobing.com has 246 employees and serves employers and job seekers in Arizona, California, Colorado, Florida, Nevada, New Mexico and Texas.
