Rio Haryanto will join Addax for the 2013 GP2 Series season.
The 19-year-old Indonesian drove for Carlin in his rookie campaign this year. Pole position in the wet at Spa was his highlight.
After several years at the forefront of the championship - including teams' titles in 2008 (as Campos) and '11 - Addax slumped to eighth in the standings this year, despite winning three races with Johnny Cecotto Jr and Josef Kral.
Team boss Alejandro Agag declared that Haryanto was the man to revitalise Addax.
"We have to admit that 2012 wasn't the greatest of seasons for us even though we were always looking to win races, like we did at three very important circuits such as Monaco, Spa and Hockenheim," said Agag.
"We have put our unconditional faith for 2013 in Rio Haryanto to get back to the level we have demonstrated in the past.
"Rio has both the motivation and experience necessary and what's more, the desire to improve and triumph, which fits in perfectly with our philosophy."
