Servicing Advances The Master Servicer and, if the Master Servicer does not, the Trustee to the extent the Trustee receives written notice from the Certificate Administrator that such Advance has not been made by the Master Servicer, shall make Servicing Advances to the extent provided in this Agreement, except to the extent that the Master Servicer or the Trustee as applicable, determines in accordance with Section 4.4 below, that any such Advance would be a Nonrecoverable Advance and, subject to the last sentence of this paragraph, except to the extent the Special Servicer determines in accordance with the Servicing Standard and Section 4.4 that such Advance, if made, would be a Nonrecoverable Advance, in which event the Special Servicer shall promptly direct the Master Servicer not to make such Advance; provided that the Special Servicer has no obligation to make such determination. Such determination by the Master Servicer or the Special Servicer shall be conclusive and binding on the Trustee and the Certificateholders and, in the case of any B Note, the holder of the related B Note and, in the case of any Serviced Pari Passu Mortgage Loan, the holder of the related Serviced Companion Loan. The Special Servicer shall not be required to make Servicing Advances under this Agreement but may make such Servicing Advances (on an emergency basis) at its option in which event the Master Servicer shall reimburse the Special Servicer for such Servicing Advance (together with Advance Interest) promptly (but no later than five (5) days) following receipt of a statement therefor. Promptly after discovering that the Master Servicer has failed to make a Servicing Advance that the Master Servicer is required to make hereunder, the Certificate Administrator shall promptly notify the Trustee (if the Certificate Administrator is not also the Trustee) in writing of the failure by the Master Servicer to make such Servicing Advance. The Master Servicer may make Servicing Advances in its own discretion if it determines that making such Servicing Advance is in the best interest of the Certificateholders, as a collective whole (and, in the case of any A/B Whole Loan, in the best interest of the holder of the related B Note and the Trust as a collective whole and, in the case of any Loan Pair, in the best interest of the holder of the related Serviced Companion Loan and the Trust as a collective whole), even if the Master Servicer or the Special Servicer has determined, in accordance with Section 4.4 below, that any such Advance would be a Nonrecoverable Advance. The applicable Non-Serviced Mortgage Loan Master Servicer is obligated to make Servicing Advances pursuant to the related Non-Serviced Mortgage Loan Pooling and Servicing Agreement with respect to any Non-Serviced Mortgage Loan, and the Master Servicer shall have no obligation or authority to make Servicing Advances with respect to such Mortgage Loan.
