The Bears and Julius Peppers finalized a six-year deal to bring the top free agent in 2010 to Chicago.
Peppers was looking for at least $12 million a year in the early part of the contract. The agreement could be worth $40 million over the first three years.
The 6-foot-7, 283-pound Peppers is a five-time Pro Bowler who recorded 10.5 sacks with two interceptions and five forced fumbles last season.
"If we bring in Julius Peppers, that could help us a lot," Bears defensive end Alex Brown said Thursday on "The Waddle & Silvy Show" on ESPN 1000. "The guy's a monster, he's an animal. He's the biggest guy and fastest guy I think I've ever seen.
"He's as gifted as [linebacker Brian] Urlacher, I think. He's just about 30 pounds heavier. He's unbelievable."
