"I'd like to thank everyone at Hampshire Cricket for all they have done for me. I leave with many great friends and fond memories.
"I enjoyed working with [head coach] Peter Moores and [captain] Glen Chapple in 2010. Their professionalism and attention to detail was particularly impressive.
"I'm hopeful that, with my experience, I can be a senior member of the squad and help a relatively young group in having a successful season in all forms of the game.
"Next year is a huge year at Old Trafford in that they're hosting another Ashes Test. Having played in an Ashes Test there before in 2005, I know it's going to be a really special time for everyone involved."
Moores added: "It is great news to have secured a player of Simon's quality and his influence will be felt both on and off the field.
"We have an emerging group of Lancashire players who will benefit greatly from his experience and knowledge, and his ability as a player is beyond question."
