I think this is a good template, here's my first attempt at adapting this idea to fit the LPVA:
Any member of the national Libertarian Party who donates at or above an amount set by the State Central Committee within one calendar year shall be considered a life member. Life members are exempt from any annual dues required for membership in the Party in perpetuity, but must meet all other membership requirements of membership, including domiciliary residency, to be considered members of the Party.
I know the "...including domiciliary residency..." is redundant if read properly, but I want to make extra sure that no one can argue that this isn't required.
