Formed in 1964, the FARC reached prominence in the 1980s and 1990s.
Concerns over lenient sentences for FARC fighters confessing to crimes was one of the major reasons Colombians voted against the deal in October.
President Juan Manuel Santos now hopes to unite his divided nation behind the new deal after the peace process was endangered by its rejection in the October plebiscite.
The revised accord is expected to be sent to Congress rather than being put to another referendum.
Other modifications to the peace deal include requiring the rebels to present an inventory of acquired money and holdings, which will be used to compensate victims.
