Which contract does this alleged damage stem from?

If there is a contract between LZ and the headhunter and it specifies such a penalty, then I assume this law does not apply. If there is a clause in the employment agreement between LZ and the employer which outlines the penalty for such a breach, then it is considered liquidated damages, which this law specifically carves out. So the question is, is this amount for this breach specifically spelled out in any of the contracts?
