14.5	This Agreement shall be subject to the laws of the Federal Republic of Germany.

14.6	The courts, competent for the Company, shall have exclusive jurisdiction for disputes arising out of this Agreement (with the exception of any disputes which arise from the General Motors Company incentive plans; for such disputes the relevant US courts shall have exclusive jurisdiction).
