With five days left to extend Tony Parker's contract before an NBA deadline, the point guard's agent said Wednesday he has ended talks with the Spurs after team officials declined to increase their six-year, $64 million offer.

"We've been told (Spurs chairman) Peter Holt won't pay a penny above $64 million," said Marc Fleisher, Parker's agent. "We respectfully think Tony's value is higher and that it just makes more sense for him to wait until the summer."

If the Spurs do not extend Parker's contract by Sunday, he will become a restricted free agent at the end of the season. The team will have the right to match any other offer he receives.

Spurs' officials, as is usually their policy during contract negotiations, declined comment.

The breakdown in negotiations comes with the two sides separated by no more than $4 million. Parker had been seeking $68 million, though a source close to the talks indicated he would be willing to compromise at $66 million.

Fleisher had been awaiting a new proposal from the Spurs this week, but was informed the team's ownership group would not increase its offer. Parker, who said last week he was "very confident" an agreement could be reached, remains hopeful the Spurs will reconsider.

"I would like to get it done, but I don't know if we will be able to," Parker said. "Marc says the Spurs' offer isn't fair. He thinks we can do better in the summer. He might be right."

The Spurs' $64 million offer would eclipse the six-year, $52 million deal Manu Ginobili signed this summer as the third-largest in the franchise's history. Only Tim Duncan (seven years, $122 million)and David Robinson (six years, $66 million)have received larger contracts.

Last summer, Washington lured Gilbert Arenas, another of the league's top young point guards, away from Golden State with a six-year, $64 million deal.

However, with NBA contract values escalating sharply over the past four months, the money Parker is seeking is substantially less than what other members of his rookie class have received.

"At those numbers, it just seems better for him to wait," Fleisher said. "I think there's a good chance he could get a max deal next summer."

Some Spurs' officials privately agree, though the team and Parker will both be taking a gamble by waiting until the summer because the league's collective bargaining agreement expires at the end of the season.

The NBA is expected to try to reduce the maximum length of guaranteed contracts as well as reduce the maximum annual raise a player can receive in the new CBA.

By waiting, Parker also puts himself at risk of injury. Any insurance policy he signs probably won't come close to guaranteeing what the Spurs are offering.

It remains to be seen how Parker will react if he enters the season without a new deal. He will earn $1.5 million this season regardless of whether he signs an extension.

"Tony went through a tough time two summers ago," Fleisher said, referring to the Spurs' failed pursuit of New Jersey point guard Jason Kidd. "And he came out of that just fine.

"He's going to have even more incentive to play well and be the max-type of player he is. What makes Tony great is that he has a lot of confidence in himself."

Spurs officials postponed negotiating with Parker until the end of September then quickly set their own Oct. 10 deadline for completing talks. Though a deal was not reached, the team continued negotiating.

Fleisher said he doubts talks will resume a second time. Even if the two sides agree on the total value of the extension, they still have to negotiate the structure of the contract, which could lead to other stumbling points.

"This is sort of what they indicated they wanted all along," Fleisher said. "I think this was specifically designed that if they got a great deal for themselves they would do it. But if they didn't, they would wait.

"I made it very clear to Tony that he has to assume when (team officials) say Peter Holt is not going to pay a penny more than $64 million, they're men of their words.

"It's not for us to tell Peter he's wrong. But at the same time we don't have to take a deal we think isn't fair value."
