A heads of terms agreement has reportedly been signed between current chairman-cum-owner David Cardoza and the buyer.
The buyout will see Cardoza sell his entire stake.
"We've been looking for investment for a while, more on a 50-50 sale - but the buyers have said they want to take control of everything," Cardoza was quoted as saying in 'BBC Sport'.
He added, "It's a bit out of the blue, but it's unquestionably in the best interests for everyone to get this deal done."
