This is my concern, who is ever going to take us off him? Let's say in a year we've failed to win promotion, Uncle Clarke pulls out, no-one is going to take on a club with 5/6 million of debt.
The club's survival then becomes "we HAVE to move", we agree a move to a small, 5k capacity multi-use stadium rented to us by Riviera Stadium Ltd, the council get a cheeky mil or two for Plainmoor, 150-odd houses get built on the site, netting Uncle Clarke a cool ~£40 million or so.
Makes throwing a few million at us a sensible (and much less charitable-seeming) investment on his behalf, I'd say.
Before I get the CO happy-clappers ask me what I'd do - get the council to agree to the above, but Riviera wipe out the debts as part of the deal / a sale and give the ground to the council, who allow us to rent it on the cheap in exchange for splitting profits of the extra facilities. Can't see any other way the club survives long-term.
