ABU DHABI: Roger Federer and Rafael Nadal plan to open the 2010 season in an exhibition tournament in Abu Dhabi.

Organizers said Tuesday that Federer and Nadal have committed to play in the three-day event starting Dec. 31. The tournament, which is not part of the ATP Tour, offers a winner-take-all prize of $250,000.

The event, organized by Abu Dhabi-based real-estate developer Capitala, features six players.

Britain's Andy Murray won the inaugural event last year, beating Federer and Nadal.
