Team principals are to hold a meeting at Renault's headquarters in Enstone on Thursday night to discuss their response to the FIA's offer of a deal to end the stand-off over entries to the 2010 championship.
As revealed by AUTOSPORT yesterday, FIA president Max Mosley has outlined the terms he would be willing to accept from the teams not currently entered - with the final deadline for them to lift conditions attached to their applications expiring tomorrow.
Mosley is offering a compromise 100 million Euro cost cap for next year, and says he is willing to address concerns about governance with a new Concorde Agreement, but only if the teams first lodge unconditional entries so changes can then be made.
With sources suggesting that the teams are not totally happy with what has been offered, a meeting of the Formula One Teams' Association (FOTA) has been arranged at Renault's team factory for 7pm local time.
No statement about the conclusions from the meeting are expected this evening, but teams have until the close of business in Europe on Friday to lift the conditions attached to their entry - or risk being left off the grid.
The FIA remains in discussion with a number of potential teams about being granted a place on the grid next year if any of the current teams are left out.
Controversially, the FIA has already put Ferrari, Red Bull Racing and Scuderia Toro Rosso on the entry list because it believes the teams made a commitment to the sport in deals they signed with the governing body and Formula One Management several years ago.
FIA president Max Mosley is expected to be at Silverstone tomorrow.
