As a rule, the articles of association are to contain provisions:
1. on becoming a member of the association and leaving it,
2. on whether the members are to make contributions, and if so, of what type these contributions are to be,
3. on the composition of the board,
4. on the prerequisites based on which the general meeting is to be convened, on the form required for convening it and on the notarial recording of the resolutions.
