Team owner Ross Brawn says he is completely confident his team will be competing in Formula 1 next year.
Brawn GP have been told by motorsport's governing body, the FIA, that they must submit an unconditional entry by this Friday if they are to race in 2010.
McLaren, BMW Sauber, Renault and Toyota are in the same position.
But Brawn thinks the impasse between the teams' umbrella group Fota and the FIA over proposed budget caps can be resolved to allow all teams to enter.
Since the FIA announced a voluntary budget cap of 100 million dollars per team for the 2010 season, Fota and the sport's governing body have continued to row over the future of F1.
On Friday all 10 current teams were included on the list of entrants for next year's championship, though five of them were on a conditional basis.
Though Fota and the FIA are still at odds over new budgetary and technical regulations, Brawn believes a solution will be found before any existing teams are ruled out of the 2010 championship.
More meetings are planned this week in an attempt to reach an agreement.
Jenson Button has won six out of seven races for Brawn's team this year and such is Brawn's confidence that they will be competing in 2010, he revealed they have already been working on next year's car.
