Kubica wanted reassurances about the new owner's plans for Renault
Robert Kubica has decided to stick with the Renault team following their sale to new owners last month.
The Pole, one of the most highly rated drivers, had a clause in his contract that allowed him to leave if the team was not wholly owned by Renault.
But he will stay for the 2010 season following talks with Luxembourg private investment group Genii Capital, which now owns 75% of the team.
Kubica wanted "clarification of the new situation", his manager told BBC Sport.
"We are going in the right direction," added Daniel Morelli. "There were no doubts, really, but it was very important we understood who were in the key roles in the team and of course also the budget - it is fundamental you have that for the updates to the car."
Asked directly whether Kubica would now definitely be driving for Renault in 2010, Morelli said: "Yes."
A Renault source confirmed that an agreement had been reached that would see Kubica drive for the team in 2010.
It's useless if the driver gets more money if you have a weak car and lose (performance) bonuses. It's better to score points and make podiums than to earn more money

Morelli denied that Kubica, who he said was planning to visit the team's Oxfordshire base this week, had been using the change of ownership to push for an increased salary.
"It is totally untrue that we were asking for more money," said Morelli.
"It is not in our interests to take advantage. We want the money for the team.
"Robert wants a performing car. It's useless if the driver gets more money if you have a weak car and lose (performance) bonuses. It's better to score points and make podiums than to earn more money."
Morelli said he and Kubica had not yet met new team owner Gerard Lopez, nor the man who the Luxembourg businessman introduced to Renault F1 staff before Christmas as the new team principal, Frenchman Eric Boullier.
Renault, which retains a 25% shareholding in the team and total ownership of the F1 engine design facility near Paris, has not yet officially confirmed Boullier's position, nor that of technical director Bob Bell.
But Morelli said he believed both men would probably be confirmed in those roles within the next two weeks.
He described the team's budget for 2010 as "reasonable" but added that he had not been told where the funding was coming from, only that Lopez planned to bring in new sponsors.
