The 10.3 billion reais payment will be "the biggest sum for a leniency agreement signed in Brazil or in the world," the federal prosecutor's office in Brasilia said.
The agreement, to be signed in "the next few days," parcels out payments over 25 years, adjusted for inflation, prosecutors said in a statement. The amount is the equivalent of about 5.6 percent of J&F revenues, they said.
Fallout from Odebrecht -- which systematically bribed politicians to win sweetheart contracts with the state oil company Petrobras -- has already seen scores of powerful political and business leaders put under investigation for bribery and embezzlement.
However, the most explosive development came last month when the owners of J&F -- whose holdings also include the trendy flip flop brand Havaianas -- implicated President Michel Temer in an alleged plot to silence a witness.
Batista and his brother Wesley have testified against Temer under plea bargains. The president is so far resisting multiple calls for his resignation, saying he did nothing wrong.
Shares in JBS lost 30 percent of their value when the scandal broke. They were up five percent in trading today.
