NEW YORK, AUG. 3 -- Timothy Busfield, who plays an ad executive in the yuppie ensemble show "thirtysomething," has settled a dispute with the makers of the ABC series and will return to work, the studio said today.

The announcement by David Gerber, chairman of the MGM-UA Television Production Group, came two days after his company sued Busfield in Los Angeles Superior Court. The suit alleged breach of contract and said that the actor, who wanted a raise, had threatened to boycott the show.

The suit said Busfield wanted $36,375 an episode, while MGM-UA had offered him $28,750 per episode. The acclaimed ABC series chronicles the lives of a group of young urban professionals as they marry, separate, have children of their own and deal with death and disease.

"There will be no further comment," said MGM-UA spokeswoman Lori Gerson when asked if the company's lawsuit was dropped. Production of the series' fourth season began yesterday in Los Angeles.

Busfield was nominated Thursday for an Emmy Award for his portrayal of ad executive Elliot Weston, whose wife's battle with ovarian cancer is expected to be a key part of the show's coming season.

He recently wrapped up a costarring role in Broadway's "A Few Good Men."
