2. Nullity shall entail the winding-up of the company, as may dissolution.
3. Nullity shall not of itself affect the validity of any commitments entered into by or with the company, without prejudice to the consequences of the company's being wound up.
4. The laws of each Member State may make provision for the consequences of nullity as between members of the company.
5. Holders of shares in the capital of a company shall remain obliged to pay up the capital agreed to be subscribed by them but which has not been paid up, to the extent that commitments entered into with creditors so require.
