The willingness of all the parties to comply with the provisions of the agreement is secured through a contractual penalty. The amount of the contractual penalty usually varies between 20,000 and 200,000 euros for each breach, and it is usually paid to the shareholders whose rights have been infringed or, if required by all the relevant parties, to the company. The infringing party usually has the right to redeem his or her shares in accordance with the bad leaver clause immediately, without vesting terms.
