Aberdeen expect to land a club record fee for Bojan Miovski and the total could rise to over PS6m.
The Dons remain in talks with Girona and a deal is expected to be finalised.
Aberdeen were yesterday waiting for the Spanish side to lodge a third bid.
Girona had put a guaranteed PS4.
2 million on the table but Aberdeen were looking for major add ons.
The Spanish side - who are part of the City Group - are expected to put in a number of add-ons worth about PS3 million and a sell-on.
There are several other European clubs who are also interested in last season's 26 goal striker but Miovski wants to move to Girona and for a crack at the Champions League.
The forward who was signed from MTK for just over PS500,000 two years ago would see Aberdeen turn over a serious profit.
The deal is eventually likely to eclipse Calvin Ramsay's sale to Liverpool and is higher than Scott McKenna's sale to Nottingham Forest.
Austrian sides LASK and Red Bull Salzburg are keen along with Italian giants AC Milan.
Bowat hasn't closed the door on a potential move to Pittodrie but it looks a longer shot with the wages on offer elsewhere.
