Nottinghamshire pace duo Andre Adams and Andy Carter have both signed two-year extensions with the county.
Former New Zealander international Adams, 34, took 43 County Championship wickets at an average of 28.46 in 2009, performances which warranted a new deal from director of cricket Mick Newell.
Newell said: "We need to get the best out of our bowlers and Andre has shown that he is a very important player for us and has the ability to contribute in all competitions.
"He'll feel that he could have done a bit more in one-day matches this season but he will be an important part of our team for at least two more seasons."
Carter, 21, made his first-class debut for the Outlaws during the 2009 season and performed regularly in Nottinghamshire's winless Pro40 Division One campaign.
Speaking to skysports.com, the 6ft 6in fast bowler said: "I am delighted to have been given a long term deal at one of the best cricket grounds in the world.
"My game has been brought on by being around brilliant players such as Chris Read, who has shown a lot of faith in me.
"I am really looking forward to the opportunity and hopefully playing more games next season."
