Four Hampshire players, including captain Jimmy Adams, have signed new contracts at the club.
Adams and all-rounders Liam Dawson and Chris Wood have agreed extensions which will keep them at Hants until 2015, while left-arm seamer James Tomlinson will prolong his stay until 2014.
All had a year or more on their deals.
"They have come through the Hampshire system and have an important part to play if we are to build on the success of 2012," said Hants boss Giles White.
"Jimmy and Tommo are both selfless, committed cricketers who put the team first. They continue to be great role models and it is good news that they have extended their stay.
"Equally, Liam and Chris are young all-rounders with real potential and, with continued development, have the opportunity to become significant contributors in all forms of the game."
Meanwhile Hampshire have also announced that assistant coach Craig White has agreed a deal to stay at the club until the end of the 2014 season.
White arrived at The Ageas Bowl last winter and took, as his main responsibility, the role of bowling coach.
He said: "I'm thrilled to sign a new two-year deal. The team's success in two competitions meant I really enjoyed my first season at Hampshire and it was an easy decision to stay on at the club. I look forward to, hopefully, enjoying more success over the next few years."
