Emery had a stellar 2012-13 season with the Chicago Blackhawks when he went 17-1-0 with a 1.94 goals-against average and a .922 save percentage. His career record is 135-75-21 with a 2.66 goals-against average and a .908 save percentage in 256 regular-season games for the Ottawa Senators, Anaheim Ducks, Blackhawks and Flyers.
The 32-year-old Zepp played in Germany for the past seven seasons.
---The Edmonton Oilers kicked off the free-agent period by signing forward Benoit Pouliot and defenseman Mark Fayne to multiyear contracts.
Pouliot's deal was for five years and Fayne's for four years. Financial terms were not disclosed by the team.
Pouliot posted 15 goals and 36 points in 80 games for the New York Rangers last season. Fayne had four goals and 11 points in 72 games for the New Jersey Devils.
Dubnyk started last season as the Edmonton Oilers starter before being traded to the Nashville Predators in January. He went 11-18-3 last season with a 3.43 goals-against average and a .891 save percentage.
The Coyotes also added checking-line center Joe Vitale to a three-year deal and defenseman Dylan Reese to a two-way contract. Vitale played for the Penguins for the past four seasons.
The 37-year-old Robidas split last season with the Dallas Stars and Anaheim Ducks, scoring five goals and 10 points in 38 games. He was traded to the Ducks at the trade after being a fixture in Dallas for over 10 years.
"He's a heart-and-soul kind of a player," Toronto general manager Dave Nonis said. "He's a player I think that at the end of every year you can look back and say he's given you everything he had. He's still a very effective player."
Robidas broke his leg in the playoffs, the second time he has suffered the injury in the past year.
"We're very comfortable that injury isn't a factor, and will not be a factor going into this season," Nonis said.
The 27-year-old Komarov played for the Maple Leafs in 2012-13 and with Moscow Dynamo of the Kontinental Hockey League this past season.
"Leo offers a lot more than I think that we even got out of him two years ago," Nonis said. "He's a better player, he's better offensively, he can play with good players. He's done that on the world stage with a pretty good hockey team.
"He's a guy that can play up and down the lineup and it was very important to us that we put a pretty good effort in to get Leo to come back here."
