Bernie Ecclestone has concluded deals with the other ten teams but has not reached an agreement with Marussia.
"We are in active discussion with the Commercial Rights Holder but, as of yesterday [Thursday], we do not have a signed agreement with them" a Marussia representative told ESPNF1.
Team principal John Booth revealed at the final test in Barcelona that "Nothing is signed yet, but it's getting pretty close now."
Booth also added that it is vital for Ecclestone to conclude a deal with his team as he will be unable to show footage of Marussia without an agreement in place.
"It's vital for Bernie because he won't be able to film us without it."
