Viacom (VIAB) and Sumner Redstone 's National Amusements have resumed talks that could see an end to their litigation and lead to the departure of Viacom Chairman Philippe Dauman, The Wall Street Journal reported Tuesday, citing people familiar with the matter.

Talks restarted in the wake of the parties' failure to clinch a deal last month, the Journal said, adding there was a possibility that the talks could fall apart altogether.

The newspaper added that under the terms being discussed, Viacom's Chief Operating Officer Tom Dooley would become chief executive.

One reason for the deadlock has been that several Viacom directors are negotiating the terms of their departure, the Journal said.

The two companies have been embroiled in controversy after National Amusements removed Dauman and others from the holding company's board. Dauman had said Shari Redstone was unduly influencing her 93-year-old father, Sumner Redstone, who lacked the mental capacity to make these decisions.

National Amusements is the privately held company that holds Redstone's nearly 80 percent of the voting shares of Viacom and CBS.
