Such investment earnings will be withdrawn from the Servicer Transition Fee Account and delivered to the Servicer. In no event shall the Master Trust Trustee be liable for any loss resulting from (i) Eligible Investments, (ii) the failure of the Servicer to provide written instructions to the Master Trust Trustee with respect to any investment, (iii) any liquidation of any such investment prior to its maturity, or (iv) funds being invested by the Master Trust Trustee in investments other than Eligible Investments, other than any loss resulting from the Master Trust Trustee’s gross negligence or willful misconduct.

(b) In the event that a Successor Servicer shall be appointed pursuant to Section 10.02 of the Agreement, the set up and servicing transition fees and costs of such Successor Servicer shall be paid for with funds on deposit in the Servicer Transition Fee Account and, if such funds are not sufficient, shall be paid by NFC, as initial Servicer. If the amount on deposit in the Servicer Transition Fee Account is insufficient to cover all of the fees and expenses associated with the transition of the servicing functions or such monthly fees and expenses, no Person will be obligated to deposit any additional funds into the Servicer Transition Fee Account. Notwithstanding the foregoing, the Servicer Transition Fee Account may be closed by the Servicer and the funds on deposit therein returned to the Servicer, if Moody’s is rating any series of securities issued by a trust formed by the Seller, upon the Servicer’s receipt of Moody’s consent to such actions; provided, that, the Servicer Transition Fee Account may not be closed so long as the Backup Servicing Agreement has not been terminated.
