NOW, THEREFORE, in exchange for good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged and confirmed), the parties hereto agree as follows:

A G R E E M E N T:

1.Definitions. Unless otherwise defined or provided herein, capitalized terms used herein have the meanings attributed thereto in (or by reference in) the Receivables Purchase Agreement.

All references in the Receivables Purchase Agreement to the term “Seller” or “Sellers” shall be deemed to include each New Seller. Without limiting the generality of the foregoing, each New Seller hereby repeats and reaffirms all covenants, agreements, representations and warranties made or given by a Seller contained in the Receivables Purchase Agreement, and appoints the Seller Representative as its agent, attorney-in-fact and representative in accordance with Section 2.5 of the Receivables Purchase Agreement.

▇▇▇▇▇▇▇▇, which account is located at a depository bank reasonably satisfactory to the Administrative Agent and which account is subject to an Account Control Agreement.

4.Amendments to Receivables Purchase Agreement. The Receivables Purchase Agreement is hereby amended as follows:

(a)Section 1.1 is hereby amended by amending and restating the definition of “Scheduled Termination Date” in its entirety as follows:

“Scheduled Termination Date” means December 24, 2020.

(b)Section 2.10(e) is hereby amended by replacing “0.4%” with “1.25%” where it appears therein.

(c)Section 2 is hereby amended to add the following Section 2.12 in appropriate numerical order as follows:

Section 2.12LIBOR Cessation. Anything in this Agreement to the contrary notwithstanding, if the Administrative Agent determines (which determination shall be binding and conclusive) that quotations of interest rates for the relevant deposits in the definition of LIBOR in Section 1.1 are not being provided in the relevant amounts or for the relevant maturities for purposes of determining the appropriate Adjusted Discount Rates applicable to the Purchased Receivables included in any Portfolio Report (whether by reason of circumstances affecting the London interbank Eurodollar market or otherwise) or adequate and reasonable means do not exist for ascertaining LIBOR or LIBOR does not adequately and fairly reflect the cost to the Administrative Agent (on behalf of the Purchasers) of funding on any Settlement Date, then the Administrative Agent (on behalf of the Purchasers) shall give the Seller Representative prompt notice thereof, and so long as such condition remains in effect, (i) no Purchased Receivables shall be discounted using LIBOR as a component of the Adjusted Discount Rate and (ii) all future Purchased Receivables shall be discounted using an Adjusted Discount Rate that is equal to the Prime Commercial Rate plus the Applicable Margin for the relevant Approved Obligor. If (i) the foregoing unavailability or inadequacy with respect to LIBOR is not of a temporary nature or (ii) the Administrative Agent determines that (A) the administrator of LIBOR or a Governmental Authority having jurisdiction over such administrator or the Administrative Agent (or any other Person on behalf of such administrator or Governmental Authority) has made or published a public statement announcing that (1) the administrator of LIBOR has ceased or will cease to provide LIBOR, permanently or indefinitely (provided that, at the time of such statement or publication, no successor administrator will continue to provide LIBOR), or (2) LIBOR is no longer representative or (B) non-recourse and limited recourse accounts receivable purchase facilities that include similar language to that contained in this Section 2.12 are being executed or amended to incorporate or adopt a new benchmark interest rate (including any mathematical or other adjustments to the benchmark (if any) incorporated therein) to replace LIBOR, then the Administrative Agent (on behalf of the Purchasers) and the Seller Representative shall negotiate in good faith with a view to agreeing upon another mutually acceptable benchmark interest rate (including any mathematical or other adjustments to such benchmark) for the Purchased Receivables and such

other related changes to this Agreement as may be applicable. For the avoidance of doubt, if such alternate benchmark interest rate as so determined would be less than zero, such rate shall be deemed to be zero for the purposes of this Agreement. Each determination by the Administrative Agent shall be conclusive absent manifest error.

(d)Section 3.6 is hereby amended by amended and restating the final paragraph as follows:

The Unused Fee distributable by the Administrative Agent to each Purchaser on each Settlement Date for each day during the preceding Settlement Period shall be equal to such Purchaser’s Pro Rata Share of the Unused Fee earned for such day; provided, however, if a Shutdown of the U.S. Government shall have occurred and be continuing on any day, no Unused Fee shall accrue with respect to such day; provided, further, that if a Shutdown of the U.S. Government shall have ceased during any calendar month, the Unused Fee shall begin to accrue on the first day of the following calendar month.

(e)Section 6.2 is hereby amended by replacing “twenty (20)” with “thirty (30)” where it appears therein.

(f)Section 8.3(d) is hereby amended by amended and restating the final paragraph as follows:

(d)

(i) No Shutdown of the U.S. Government has occurred and is continuing and (ii) no Shutdown of the U.S. Government occurred or was continuing at any time during the calendar month during which such Purchase Date occurs; provided that if consented to by the Administrative Agent and the Purchasers in writing in advance of any purchase, the foregoing limitation will not apply to any Non-Affected Receivables.
