Yeah, it's not great.
Some good stuff - guaranteed director, guaranteed observer, 5% of the voting rights regardless. If there's a future sale of the Class B shares by the majority owners then the Trust gets tag along rights too. The board meeting stuff. Now, we could say that's stuff we already had as part of the original SHA, but hey ho.
As for the rest, not great. 5% of the shareholding now holds no real economic value, and any dividend return is likely to be diminished over time (divi's will be based on shareholding not voting rights). The Trust can't sell that 5% even if wanted to. If there is a future sale the Trust can either sell all of their holding or none, nothing in between. No veto rights or anything like that, not even on basic stuff that would be meaningless to the others, such as the club's name and colours.
It does also seem that some wordsmithing has been going on in terms of the answers given to the members, with regards to dividends. Unless there's something in the SHA there's absolutely no protection in the event of SCFC LLC being sold, leaving the Trust high and dry.
We'll never know what's in the SHA by the looks of things, but a) I hold out little hope it's meaningful and b) christ knows what surprises might be in there.
As it stands, I think this is now worse than simply walking away from the legal case. It's an agreement that gives the impression of providing protections but actually doing the opposite.
