to Section 6.13 of the Indenture, or payment otherwise of any fees and expenses as Trustee under the Indenture for any reason at a time when the Resigning Trustee has not been fully paid, it shall do so for both its own fees and expenses and
the outstanding fees and expenses of the Resigning Trustee, incurred in connection with its duties under the Indenture prior to the effective date of this Instrument, the execution and delivery of this Instrument and any subsequent transitional
services requested by the Successor Trustee from the Resigning Trustee after the effective date of this Instrument. The Successor Trustee, after payment of its own fees and expenses and those of its counsel, shall promptly pay over a pro rata
portion of any and all such proceeds to the Resigning Trustee when and as received. To the extent the Resigning Trustee receives funds from the Issuer, other than for payment of the Resigning Trustee’s fees and expenses or other amounts that
the Resigning Trustee is otherwise entitled to receive, it agrees to hold those funds as agent for the Successor Trustee and promptly pay over such funds to, or as directed by, the Successor Trustee.

 Section 403. Notwithstanding the resignation of the Resigning Trustee effected
hereby or any other provisions hereof, the Issuer and the Guarantors shall remain obligated under Section 7.07 of the Indenture to compensate, reimburse and indemnify the Resigning Trustee in connection with its service under the Indenture as
Trustee, Registrar, and Paying Agent to the same extent as if no resignation shall have occurred, including with respect to reasonable fees and expenses related to the Litigation incurred by the Resigning Trustee. The Issuer also acknowledges and
reaffirms its obligations to the Successor Trustee as set forth in Section 7.07 of the Indenture, including its obligation to pay the reasonable fees and expenses (including the reasonable fees and expenses of counsel) incurred by the Successor
Trustee in the Litigation, which obligations shall survive the execution hereof. For the avoidance of doubt, for priority purposes, any fee and/or expense claim arising against the Issuer on account of this Instrument shall be treated as a claim
arising out of the Indenture and shall be afforded the same priority against the Issuer as any fee or expense claim arising out the Indenture.
