NEW YORK -- No one on either side of the NHL labor fight stormed out of the room, broke off negotiations, or made inflammatory remarks as they left the building.

Quite the contrary, actually.

While negotiators for the league and the union declined to say whether significant progress was made on Day 54 of the lockout, owners and players agreed to return to the bargaining table on Friday for the fourth straight day of talks.

"I am not going to characterize it except to say, as I have before, that it's always better when you're meeting than when you're not," players' association executive director Donald Fehr said Thursday night after the sides wrapped up more than five hours of talks.

It wasn't clear if the NHL responded favorably to a pair of offers the league received from the union on Wednesday or if it made counterproposals to players on Thursday. Both sides held internal meetings to go over the latest developments and make preparations for another set of talks on Friday.

"I am not going to discuss the negotiations or the substance of what we're talking about," NHL Commissioner Gary Bettman said Thursday on a wind-blown street corner. "I really don't think that would be helpful to the process.

"We have work to do, and my hope is that we can achieve the goal of getting a long-term, fair agreement in place as quickly as possible so we can play hockey."

The atmosphere was positive enough that Fehr didn't rule out the possibility that talks could stretch into the weekend, too.

This week is considered critical for the season to be saved. The work stoppage is threatening to force the second cancellation of an NHL season in seven years.

Even if an agreement is reached soon, it isn't clear if any of this season's games that have been called off through Nov. 30 can be rescheduled. The NHL has already said a full 82-game season won't be played.

During a second consecutive day of marathon negotiations Wednesday, the players' association made an offer on revenue sharing, in which richer teams would help out poorer organizations, and another proposal regarding the "make-whole" provision that would guarantee full payment of all existing multiyear player contracts.

Thursday's discussions marked the fourth time in six days that face-to-face negotiations have taken place after both sides rejected proposals Oct. 18. The lockout, which began Sept. 16 after the collective bargaining agreement expired, has forced the cancellation of 327 regular-season games, including the New Year's Day Winter Classic in Michigan.

It was unclear if the NHL made counterproposals to offers it received from the union on Wednesday. The belief is that the players' association has agreed to a 50-50 split of hockey-related revenues, but that even division wouldn't kick in until the third year of the deal.

Revenue sharing and the make-whole provision are major hurdles in the way of making a deal. On Wednesday, the sides spent more than five hours dealing with the most contentious areas. Coupled with the more than seven hours they spent negotiating Tuesday, owners and players were together about 13 hours this week before reconvening Thursday.

There is clearly still much to be done to work out the differences to reach a deal that will allow the delayed and shortened season to begin.

Along with a handful of team owners, eight players attended Wednesday's talks, five fewer than Tuesday. Pittsburgh Penguins captain Sidney Crosby and others left New York to try to avoid the impending snowstorm that hit the area, the union said.

On Thursday, seven players were in attendance, according to the NHLPA, and at least three owners.

In October, the players' association responded to an NHL offer with three of its own, but all of those were quickly dismissed by the league. That led to nearly three weeks without face-to-face discussions, although the parties kept in regular contact by phone.

Both sides have made proposals that included a 50-50 split of hockey-related revenues. The NHL has moved toward the players' side in the "make-whole" provision and whose share of the economic pie that money will come from.

Along with the split of hockey-related revenue and other core economic issues, contract lengths, arbitration and free agency also must be agreed upon.

The union accepted a salary cap in the previous labor pact, which wasn't reached until after the entire 2004-05 season was canceled because of a lockout. The union doesn't want to absorb the majority of concessions this time after the NHL had record revenue that exceeded $3 billion last season.
