Discussions over a new deal are continuing between the rebranded Mercedes Grand Prix and Formula One world champion Jenson Button for the 2010 season.
Nick Fry, who will remain as chief executive following the Mercedes takeover of Brawn GP, said the team wanted to keep the Briton but had financial constraints to keep in mind.
"We have had discussions with Jenson about what we think is a sensible salary," he told Radio Five Live.
Around 75.1% of Brawn GP will be bought by the German manufacturer in partnership with an Abu Dhabi investment firm and the team will be rebranded as the Brackley-based Mercedes Grand Prix.
Fry also made light of rumours that the buy-out might result in an all-German driver line-up as reports suggest that Nico Rosberg has already been signed as the new manufacturer's number one, with Button tipped for a McLaren move.
Nick Heidfeld and Timo Glock, also Germans, have been linked to the number two spot.
"I can confidently say that is totally incorrect - Mercedes is an international company," Fry added.
"Clearly, a German driver would be nice for them but we don't need two German drivers, that's not the intention."
