63 US-DOCS\149870611.184871-1379-4480 v.21 US-DOCS\152880138.1 (c) Payments Free of Taxes. Any and all payments by or on account of any Obligation shall be made without deduction or withholding for any Taxes, except as required by any Law. If any Law (as determined in the good faith discretion of the Company or the Administrative Agent, as applicable) requires the deduction or withholding of any Tax from any such payment by the Company or the Administrative Agent, then the Company or the Administrative Agent, as applicable, shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable Laws and, if such Tax is an Indemnified Tax, then the sum payable by the Company shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 5.10) the Purchasers receive an amount equal to the sum they would have received had no such deduction or withholding been made. (d) Payment of Other Taxes by Company. The Company shall timely pay to the relevant Governmental Authority in accordance with applicable Law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes. (e) Indemnification by the Company.

A certificate as to the amount of such payment or liability delivered to the Company by a Purchaser shall be conclusive absent manifest error. (f) Evidence of Payments. As soon as practicable after any payment of Taxes by the Company to a Governmental Authority pursuant to this Section 5.10, the Company shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. (g) Treatment of Certain Tax Benefits. If any party to this Agreement determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 5.10 (including by the payment of additional amounts pursuant to this Section 5.10), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 5.10 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 5.10(g) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 5.10(g), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 5.10(g)the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject

(c) If any claim, demand, action or proceeding (including any investigation by any Governmental Authority) shall be brought or alleged against an indemnified party in respect of which indemnity is to be sought against an indemnifying party pursuant to the preceding paragraphs, the indemnified party shall, promptly after receipt of notice of the commencement of any such claim, demand, action or proceeding, notify the indemnifying party in writing of the commencement of such claim, demand, action or proceeding, enclosing a copy of all papers served, if any; provided, that the omission to so notify such indemnifying party will not relieve the indemnifying party from any liability that it may have to any indemnified party under the foregoing provisions of this Section 7.05 unless, and only to the extent that, such omission results in the forfeiture of, or has a material adverse effect on the exercise or prosecution of, substantive rights or defenses by the indemnifying party. In case any such action is brought against an indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not

(d) In the event that an Erroneous Payment (or portion thereof) is not recovered by the Administrative Agent for any reason, after demand therefor by the Administrative Agent in accordance with immediately preceding clause (a), from any Purchaser that has received such Erroneous Payment (or portion thereof) (and/or from any Payment Recipient who received such Erroneous Payment (or portion thereof) on its respective behalf) (such unrecovered amount, an “Erroneous Payment Return Deficiency”), upon the Administrative Agent’s notice to such Purchaser at any time, then effective immediately (with the consideration therefor being acknowledged by the parties hereto), (i) such Purchaser shall be deemed to have assigned its Assigned Interests (but not its Commitments) with respect to which such Erroneous Payment was made (the “Erroneous Payment Impacted Assigned Interests”) in an amount equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Administrative Agent may specify) (such assignment of the Assigned Interests (but not Commitments) of the Erroneous Payment Impacted Assigned Interests, the “Erroneous Payment Deficiency Assignment”) (on a cashless basis) (with the assignment fee to be waived by the Administrative Agent in such instance), and is hereby (together with the Company) deemed to execute and deliver an assignment and assumption agreement with respect to such Erroneous Payment Deficiency Assignment, and such Purchaser shall deliver any notes or other instruments evidencing such Assigned Interests to the Company or the Administrative Agent (but the failure of such Person to deliver any such notes shall not affect the effectiveness of the foregoing assignment), (ii) the Administrative Agent as the assignee Purchaser shall be deemed to have acquired the Erroneous Payment Deficiency Assignment, (iii) upon such deemed acquisition, the Administrative Agent as the assignee Purchaser shall become a Purchaser, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment and the assigning Purchaser shall cease to be a Purchaser, as applicable, hereunder

85 US-DOCS\149870611.184871-1379-4480 v.21 US-DOCS\152880138.1 with respect to such Erroneous Payment Deficiency Assignment, excluding, for the avoidance of doubt, its obligations under the indemnification provisions of this Agreement and its applicable Commitments which shall survive as to such assigning Purchaser, (iv) the Administrative Agent and the Company shall each be deemed to have waived any consents required under this Agreement to any such Erroneous Payment Deficiency Assignment, and (iv) the Administrative Agent may reflect in the Register its ownership interest in the Assigned Interests subject to the Erroneous Payment Deficiency Assignment.

(g) Each party’s obligations, agreements and waivers under this Section 8.14 shall survive the resignation or replacement of the Administrative Agent, any transfer of rights or obligations by, or the replacement of, a Purchaser, the termination of the Commitments and/or the

86 US-DOCS\149870611.184871-1379-4480 v.21 US-DOCS\152880138.1 repayment, satisfaction or discharge of all Obligations (or any portion thereof) under any Transaction Document. [SIGNATURE PAGE FOLLOWS]
