According to TSN, Campoli was awarded $2.5 million in arbitration.
Last week, Blackhawks general manager Stan Bowman said Campoli would not be back with the team next season.
"It was apparent from the beginning their salary demands were just not in concert with where we see him fitting in our team," Bowman said at that time. "We had to make a decision (that) it wasn't going to happen. We made our best offer and it wasn't to his liking. He sees himself in a different category, price-wise."
Campoli, 26, was acquired from Ottawa at the trade deadline last season for forward Ryan Potulny and a draft pick. He played in 19 regular-season games and all seven postseason contests, combining for one goal and seven assists. He gave a puck away in overtime of Game 7 against the Vancouver Canucks which turned into the winning goal.
