SBS Support for MMCLT's Purchase of Minsterley Meadows SSSI

1.Should SBS pledge financial support to help MMCLT buy Minsterley Meadows SSSI?
2.If no, do you agree to other forms of support by SBS:
3.If yes, how much would you agree is the right amount for SBS to pledge (no strings attached, and providing no money leaves our coffers if MMCLT fail to reach the target and providing SBS is not financially compromised into the future by parting with the cash)
4.Do you have any other suggestions or comments?
