Legal analysis: the guarantee contract is a subsidiary contract of the main contract. The main contract is invalid, and the guarantee contract is invalid. If there are other provisions in the guarantee contract, such provisions shall prevail. That is to say, if the creditor's rights of the main contract do not exist because the main contract is invalid, then the guarantee contract loses the object of guarantee, and the guarantee contract also becomes invalid with the invalidity of the main contract. However, if it is expressly agreed that the validity of the main contract will not affect the validity of the guarantee contract, when the main contract is invalid, the guarantor shall bear the guarantee liability in accordance with the stipulations of the effective guarantee contract.

Legal basis: The following exemption clause in Article 506 of General Principles of Civil Law of People's Republic of China (PRC) is invalid:

(1) Causing personal injury to the other party;

(2) Causing property losses to the other party due to intentional or gross negligence.
