Despite last year's proposed deal failing to materialise, talks are continuing between Lotus and Quantum.
Last year Quantum had planned to buy a stake in the Lotus but that never happened with banking complications billed as the reason.
This led to Lotus chairman Gerard Lopez saying as recently as this week that the deal was over.
However, according to Lotus shareholder Andrew Ruhan is could yet take place.
"At this moment of time, the original structure of the deal cannot be completed," Ruhan, who owns a two per cent stake in the team, told Autosport.
"However, we maintain discussions with Mansoor [Ijaz] and still believe it is possible that a deal on a similar basis can be concluded."
But even if the Quantum deal never goes through, Ruhan is not worried about Lotus' future.
"This team is very stable - and we have taken action to make sure the future is secure," he added.
"Should talks be successful with Quantum then it will be a bonus, but we are not dependent on it happening."
