Edinburgh businesswoman Ann Budge has been revealed as the main backer behind fans' group the Foundation of Hearts' proposed takeover of the Tyncastle club.
The multi-millionaire, a season ticket holder at the Scottish Premiership side, is the sole diector of BIDCO, the company which was formed by the FoH to take over the running of the club once it exits administration.
BIDCO has come to a £2.5m agreement with administrators BDO to buy the near 79 per cent stake in the club held by Lithuanian company UBIG, the club's majority shareholder.
The rescue package would see FoH fund the upfront capital of £2.5m to enable the CVA to be completed and for the club to exit administration, while, as director of BIDCO, Ann Budge would become executive chairman of Hearts on a no-fee basis.
In preparation for supporter ownership, BIDCO would run the club for at least three years, via a newly-appointed board, with representation from the FoH.
In a statement on the club's official website, the Foundation of Hearts, who claim they are unable to go into the finer points of the deal, said: "This agreement would see the club exit administration, be returned to a position of financial stability and ultimately see majority ownership of the club passed to its supporters.
"Legal agreements are not yet in place with the current owners given the delays that have ensued with regard to completing the share transfer.
"For this reason BIDCO is unable to enter into public discussion regarding details of the rescue package or future plans for the club."
Hearts, who currently prop up the Premiership table, were docked 15 points after entering administration with debts of over £20m last summer.
