Gloucestershire paceman Liam Norwell will join Warwickshire at the end of the current season.
The 26-year-old has racked up 283 wickets in all formats and enjoyed a breakthrough red-ball campaign last season with 59 scalps at an average of 17.39 in Division Two of the Specsavers County Championship.
He has agreed a three-year deal at Edgbaston.
Norwell said: "I'm really excited to be joining Warwickshire.
"The club has a lot of ambition, a great coaching set-up and a squad that I believe can compete in all formats for silverware and be successful for a long period.
"I've really enjoyed my time with Gloucestershire, but right now I feel it's time for a new challenge to try and push myself to be as successful as I can in cricket and for Warwickshire and Birmingham Bears."
