Last July, Martin signed a two-year contract with Hendrick Motorsports covering one full Sprint Cup season in 2009 and one part-time schedule of 26 events in 2010. The revised agreement was signed this week.
"Week in and week out, Mark continues to be one of the best race car drivers in the world," Hendrick said. "He's already made an incredible contribution to Hendrick Motorsports, and our entire company is excited about running another full season and winning races with him in 2010."
