All 10 existing Formula One teams were included on the 2010 entry list on Friday along with two new US-based operations and one from Spain.
The governing International Automobile Federation (FIA) said that McLaren, BMW-Sauber, Renault, Toyota and Brawn are all conditional entries, however, with further discussions to be concluded by June 19.
Champions Ferrari, the two Red Bull teams, Williams and Force India were deemed to be unconditional.
Spain's Campos Grand Prix and the American-based US F1 and Manor Grand Prix operations were also included in an expanded line-up of 13 teams.
