Notwithstanding anything to the contrary herein, any liability of each of the Lender or any other Lender towards the Security Provider under this Security Agreement shall not be joint and several (nicht solidarisch) but separate and independent.

12. Bank Secrecy Waiver

The Security Provider explicitly authorizes the Lender to request from the Custodian and the Custodian to provide the Lender and|or the other Lender with, any data regarding the Securities Account, the Securities and the Related Rights and the Security Provider hereby explicitly waives its banking secrecy and data protection rights in this regard.
