LOS ANGELES (AP) — Shelly Sterling reached an agreement Thursday night to sell the Los Angeles Clippers to former Microsoft CEO Steve Ballmer for $2 billion in what would be a record deal if approved by the NBA, according to an individual with knowledge of the negotiations.

The individual, who wasn’t authorized to speak publicly, told The Associated Press that Ballmer and the Sterling Family Trust now have a binding agreement. The deal now must be presented to the NBA.

Shelly Sterling negotiated the sale after her husband, Donald Sterling, made racist remarks that were made public. The remarks included Sterling telling girlfriend V. Stiviano not to bring blacks to Clippers games, specifically mentioning Hall of Famer Magic Johnson. Donald Sterling must also approve the final agreement as a 50 percent owner.

Ballmer beat out bids by Guggenheim Partners and a group including former NBA All-Star Grant Hill.

On Thursday, Magic Johnson posted on his Twitter account: “Steve Ballmer owning the Clippers is a big win for the City of LA and all the people who live in the City of Angels!”

It’s unclear if the deal will go through. The individual said that though Donald Sterling was not involved in the negotiations, “at the end of the day, he has to sign off on the final process. They’re not going to sell his 50 percent without him agreeing to it.”

Donald Sterling’s attorney says that won’t happen. “Sterling is not selling the team,” said his attorney, Bobby Samini. “That’s his position. He’s not going to sell.”

That’s despite a May 22 letter obtained by The Associated Press and written by another one of Sterling’s attorneys that says that “Donald T. Sterling authorizes Rochelle Sterling to negotiate with the National Basketball Association regarding all issues in connection with a sale of the Los Angeles Clippers team.” It includes the line “read and approved” and Donald Sterling’s signature.

Samini said Sterling has had a change of heart primarily because of “the conduct of the NBA.” He said NBA Commissioner Adam Silver’s decision to ban Sterling for life and fine him $2.5 million as well as to try to oust him as an owner was him acting as “judge, jury and executioner.”

“They’re telling me he should stand back and let them take his team because his opinion on that particular day was not good, was not popular?” Samini said. “That his team should be stripped from him? It doesn’t make sense. He’s going to fight.”

The person with knowledge of the deal said that any buyer would have to ensure the team remains in Los Angeles and be someone Shelly Sterling could work with if she decides to retain a small stake. An attorney representing Shelly Sterling declined to comment Thursday.

It’s unclear how the agreement will affect a special hearing of NBA owners planned for Tuesday in New York to consider the charge against Donald Sterling for damaging the league with his comments. A three-quarters vote of the 30 owners to support the charge would have resulted in the termination of both Sterlings’ ownership of the franchise.

Silver has said his preference would be for the franchise to be sold rather than seized — and that means sold in its entirety, with neither Sterling retaining a stake.

Franchise sale prices have soared since the current collective bargaining agreement was ratified in 2011. The Milwaukee Bucks were just sold to New York investment firm executives Marc Lasry and Wesley Edens for about $550 million, an NBA record.

Last year, Vivek Ranadive’s group acquired a 65 percent controlling interest in the Sacramento Kings at a total franchise valuation of more than $534 million.

The bid for the Clippers, purchased by Sterling in 1981 for a little more than $12 million, blew right past those.

It is not Ballmer’s first foray into potential NBA ownership. Ballmer and investor Chris Hansen headed the group that agreed to a deal to buy the Kings from the Maloof family in January 2013 with the intention of moving them to Seattle, where the SuperSonics played until 2008.

But Sacramento Mayor Kevin Johnson lobbied the NBA for time to put together a bid to keep the team in California, and though the Ballmer-Hansen group later increased its offer, owners voted to deny the bid for relocation and the Kings were sold to Ranadive.

The former Microsoft CEO helped Bill Gates transform the company from a tiny startup with fewer than 40 employees and $12 million in annual revenue into the world’s most valuable business. The pair met in 1973 while living down the hall from each other at a Harvard dorm.

During his tenure at Microsoft, Ballmer was known for his competitive drive and wild displays of emotion and hand-waving.

At his farewell address to Microsoft employees, he high-fived and hugged audience members, pumped his fists in the air, and even shed tears as the popular 1987 song “(I’ve Had) The Time of My Life” played on the sound system. In a video of the event widely viewed on YouTube, he screams: “You work for the greatest company in the world!”
