Vince Ferragamo, the former Los Angeles quarterback who led the Rams to Super Bowl XIV before becoming a free agent, signed a four-year contract tonight with the Canadian Football League's Montreal Alouettes.

Details of the agreement with Ferragamo, 27, were not disclosed, but his salary is believed to be $400,000 per season. The package is also believed to include a clause giving him a share of the gate receipts each time attendance tops 40,000 at Montreal's Olympic Stadium.

The Alouettes also announced the signing of 29-year-old wide receiver James Scott, who played out his option with the Chicago Bears. Scott signed a three-year contract, team officials said.

Last season, Scott caught 36 passes for the Bears for 696 yards, an average of 19.3 yards per catch.

The signing of Ferragamo had been expected for a month, every since Vancouver tycoon Nelson Skalbania agreed to purchase the Alouettes from Sam Berger. The sale was completed today.

"I'm glad the suspense is over," said Ferragamo, who was the No. 1 Ram quarterback last year after an injury sidelined Pat Haden.

Ferragamo said he took so long to reach a decision because it was "the biggest decision of my life. I had to take my time."

While he was pondering his future, he said, former Ram teammates tried to dissuade him from the move.

". . . The contract was the main reason why I signed. It was something I just couldn't turn down," Ferragamo said.

Last season, Ferragamo, who reportedly made $52,000 with the Rams, completed 240 of 404 passes for 3,199 yards and 30 touchdowns.

"The first thing I thought about when I bought the Alouettes was that there were 600,000 empty seats in the CFL last season, and we had half of them," Skalbania said. "Ferragamo came to mind. I'd rather have a high-scoring game -- even if we had to lose, 38-39, instead of winning, 3-0, and you can only do that with an exciting, throwing quarterback."
