Steven Pienaar, the South African international, joined Everton on a season-long loan from Borussia Dortmund in July 2007, and the Toffees are keen to secure his services long-term.
"We are quite comfortable with it at the moment. The fee is agreed."
"I think he's enjoying himself," added Moyes. "He feels wanted here. He's comfortable with the surroundings.
"It's easier that he has other African players here as well. He would tell you that he's really enjoying his spell here. Does it surprise me that he's doing well? He was very good at Ajax.
"What worried me was that he went to Borussia Dortmund and it didn't happen for him. His stature sometimes gave me the feeling that there was no strength there."
