such claim at its expense and through counsel of its choosing.

Trustee, to execute, acknowledge and deliver such

confirming to the Successor Trustee all rights, powers, trusts, privileges, duties and obligations which the Prior Trustee held under and by virtue of the Indenture. 
 10. Survival of Issuer’s Obligations. Notwithstanding the resignation of the Prior Trustee, the Issuer’s obligations under Section 8.07 shall continue for the benefit of the Prior Trustee with
