LOS ANGELES: NBC said Thursday it has reached a $45 million deal with Conan O'Brien for his exit from the "Tonight" show, allowing Jay Leno to return to the late-night program he hosted for 17 years.

Under the deal, which came seven months after O'Brien took the reins from Leno, O'Brien will get more than $33 million, NBC said. The rest will go to his 200-strong staff in severance, the network said in an announcement on the "Today" show.

His final show will be Friday, with Tom Hanks scheduled to appear as well as Will Ferrell — the first guest O'Brien welcomed as "Tonight" host last June — and musical guest Neil Young.

Leno will return to "Tonight" on March 1.

"In the end, Conan was appreciative of the steps NBC made to take care of his staff and crew, and decided to supplement the severance they were getting out of his own pocket," his manager, Gavin Polone, told The Wall Street Journal. "Now he just wants to get back on the air as quickly as possible."

O'Brien will be free to begin another TV job as soon as September, NBC said.

A spokesman for O'Brien said he would be unavailable for comment.

O'Brien landed the "Tonight" show after successfully hosting "Late Night," which airs an hour later, since 1993. But he quickly stumbled in the ratings race against his CBS rival, David Letterman.

Under Leno, the "Tonight" show was the ratings champ at 11:35 p.m. Eastern, but he proved an instant flop with his experiment in prime time.

Last week NBC announced that the five-hour vacancy in prime time left by Leno will be filled by scripted and reality fare calculated to bring NBC affiliates a more robust lead-in audience for their local news than Leno had been delivering. A provisional slate of shows will include new and veteran NBC dramas, a comedy panel series produced by Jerry Seinfeld and "Dateline NBC."

It had been no secret that the 46-year-old O'Brien was scoring puny ratings numbers on "Tonight," averaging 2.5 million nightly viewers, compared with 4.2 million for Letterman's "Late Show," according to Nielsen figures.

It was even more obvious that "The Jay Leno Show," airing weeknights at 10 p.m. Eastern, was a disaster. Mostly justified by the network for its bargain-basement production budget, it not only was critically slammed, but also found a disappointing popular reaction. It has averaged 5.3 million nightly viewers since its fall debut — about the same number that watched Leno's final "Tonight" season, in a time slot when far fewer viewers are available. By comparison, the season's top-rated 10 p.m. network drama, CBS' "The Mentalist," has an average audience of 17 million.
