(a) Clause (d) of the preamble to the Receivables Purchase Agreement is amended and restated in its entirety to read as follows:

“(d) Chariot Funding LLC, a Delaware limited liability company, and its assigns hereunder (collectively, the “Chariot Committed Purchasers” and, together with Chariot in its capacity as Conduit, the “Chariot Group”), The Bank of Nova Scotia, a Canadian chartered bank (“Scotiabank”), and its assigns hereunder (collectively, the “Liberty Street Committed Purchasers” and, together with Liberty Street, the “Liberty Street Group”) and Wells Fargo Bank, N.A., a national banking association (“Wells Fargo”), and its assigns hereunder (collectively, the “Wells Fargo Committed Purchasers” or the “Wells Fargo Group”),

(b) Section 3.1 of the Receivables Purchase Agreement is hereby amended and restated in its entirety to read as follows:

“Section 3.1 CP Costs. Seller shall pay CP Costs with respect to the Capital funded by any Conduit or Committed Purchaser through issuing Commercial Paper for each day that any such Capital is outstanding. Capital funded by a Conduit substantially with Pooled Commercial Paper will accrue CP Costs each day on a pro rata basis, based upon the percentage share such Capital represents in relation to all assets held by such Conduit and funded substantially with related Pooled Commercial Paper.”

(c) Section 4.1 of the Receivables Purchase Agreement is hereby amended and restated in its entirety to read as follows:

“Section 4.1 Committed Purchaser Funding. Any portion of the Capital funded by the Committed Purchasers in a Group that has not been funded through the issuance of Commercial Paper, shall accrue Yield for each day during each Tranche Period at either the LIBO Rate, the Transaction Rate or the Prime Rate in accordance with the terms and conditions hereof.

If the Committed Purchasers in a Group acquire by assignment from the applicable Conduit any interest in a Purchaser Interest pursuant to a Liquidity Agreement, Capital allocable to each interest so assigned shall each be deemed to have a new Tranche Period commencing on the date of any such assignment.”

(d) Section 4.6 of the Receivables Purchase Agreement is hereby amended and restated in its entirety to read as follows:

“Section 4.6 Liquidity Agreement Fundings.

(a) The parties hereto acknowledge that each Conduit may assign all or any portion of its Purchaser Interests to the Committed Purchasers in its Group at any time pursuant to its Liquidity Agreement to finance or refinance the necessary portion of its Purchaser Interests through a funding under such Liquidity Agreement to the extent available. The fundings under each Liquidity Agreement will accrue Yield in accordance with this Article IV. Regardless of whether a funding of Purchaser Interests by Committed Purchasers constitutes the direct purchase of an interest in Purchaser Interests hereunder, an assignment under the applicable Liquidity Agreement of an interest in Purchaser Interests originally funded by a Conduit or the sale of one or more participations or other interests under such Liquidity Agreement of an interest in a Purchaser Interest originally funded by a Conduit, each Committed Purchaser participating in a funding of an interest in Purchaser Interests shall have the rights and obligations of a “Purchaser” hereunder with the same force and effect as if it had directly purchased such interest from Seller hereunder.

(b) The Chariot Group Committed Purchaser and the Chariot Agent, represent and warrant that they are parties to the Chariot Liquidity Agreement relating to the Purchaser Interests, under which JPMorgan Chase as an “APA Bank” under the Chariot Liquidity Agreement has issued a “Commitment” to the Committed Purchaser to purchase the Purchaser Interest (or any portion thereof or interests therein), or make limited recourse loans in respect of the Purchaser Interest in at least all circumstances in which the Chariot Committed Purchaser is required to make any purchase hereunder. Each of the Chariot Conduit and Chariot Committed Purchaser agrees that, to the extent the Chariot Committed Purchaser is unable to purchase all or any portion of the Chariot Group’s Percentage of a Purchase Price specified in a Purchase Notice delivered in accordance with Section 1.2 (the “Purchase Deficit”) through the issuance of Commercial Paper, it will enforce its rights under the Chariot Liquidity Agreement against the APA Bank in order to fund such Purchase Deficit. The Chariot Agent agrees that (A) to the extent the Chariot Committed Purchaser is unable to purchase such Purchase Deficit through the issuance of Commercial Paper, it will cause the Chariot Conduit and the Chariot Committed Purchaser to enforce their rights under the Chariot Liquidity Agreement against the APA Bank in order to fund such Purchase Deficit, (B) it will ensure that all times that its Commitment will be supported in full by a “Commitment” from the APA Bank under the Chariot Liquidity Agreement and (C) it will ensure that Chariot will not enter into an asset purchase agreement with another APA Bank without the consent of the Seller (which consent will not be unreasonably withheld). The Chariot Agent agrees to notify the Seller at least thirty (30) days prior to the effective date of any proposed amendment, supplement or modification to the Chariot Liquidity Agreement that would adversely affect the interests of the Seller.”

4

Agreement or any other Funding Agreement or a Purchaser’s or Affected Entity’s obligations under this Agreement or any other Funding Agreement, or on or with respect to the Receivables or (ii) imposes, modifies or deems applicable any reserve, assessment, fee, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or liabilities of an Affected Entity or a Purchaser, or credit extended by an Affected Entity or a Purchaser pursuant to this Agreement or any other Funding Agreement (except the reserve requirement reflected in the LIBO Rate) or (iii) imposes any other condition affecting this Agreement or any Funding Agreement and the result of any of the foregoing is to increase the cost to an Affected Entity or a Purchaser of performing its obligations under this Agreement or any other Funding Agreement, or to reduce the rate of return on an Affected Entity’s or Purchaser’s capital as a consequence of its obligations under this Agreement or any other Funding Agreement, or to reduce the amount of any sum received or receivable by an Affected Entity or a Purchaser under this Agreement or any other Funding Agreement, or to require any payment calculated by reference to the amount of interests or loans held or interest received by it then, on the forty-fifth (45th) day after demand by the related Co-Agent, Seller shall pay to such Co-Agent, for the benefit of the relevant Affected Entity or Purchaser, such amounts charged to such Affected Entity or Purchaser or such amounts to otherwise compensate such Affected Entity or such Purchaser for such increased cost or such reduction; provided, that solely in the case of a Regulatory Change of the type described in clause (iii) of the definition thereof, Seller shall only be liable for amounts in respect of increased costs or reduced returns for the period of up to ninety (90) days prior to the date on which such demand was made.”

(l) The Receivables Purchase Agreement is hereby amended by adding the following Section 10.4 immediately following Section 10.3 thereof:

“Section 10.4 Taxes

(a) Any and all payments by or on account of any obligation of the Seller under any Transaction Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of the Seller) requires the deduction or withholding of any Tax from any such payment by the Seller, then the Seller 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 law and, if such Tax is an Indemnified Tax, then the sum payable by the Seller 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 10.4) the applicable Indemnified Party receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(b) The Seller shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the written request of the applicable Indemnified Party timely reimburse it for the payment of, any Other Taxes.

(c) The Seller shall indemnify each Indemnified Party, on the first Monthly Payment Date which is at least 45 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 10.4) payable or paid by such Indemnified Party or required to be withheld or deducted from a payment to such Indemnified Party and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or

5

legally imposed or asserted by the relevant Governmental Authority. The Administrative Agent and each Co-Agent will promptly notify the Seller of any event of which it has knowledge, which will entitle it or any Funding Source in its Group to compensation pursuant to this Section 10.4; provided, however, that failure of any Indemnified Party to demand indemnification for any Taxes shall not constitute a waiver of such right to indemnification, except that the Seller shall not be required to indemnify an Indemnified Party for Taxes under this Section 10.4 unless such Indemnified Party notifies the Seller of such claim no later than 45 days after such Indemnified Party has knowledge of such Taxes being imposed or arising. Any notice claiming compensation under this Section 10.4 shall set forth in reasonable detail the additional amount or amounts to be paid to it hereunder and shall be conclusive in the absence of manifest error. Absent manifest error, the Seller shall be obligated to any claim for tax indemnity promptly upon receipt of such notice.

(d) Each Indemnified Party agrees that it will use reasonable efforts to reduce or eliminate any claim for indemnity pursuant to this Section 10.4, including, subject to applicable law, a change in the funding office of such Indemnified Party; provided, however, that nothing contained herein shall obligate any Indemnified Party to take any action that imposes on such Indemnified Party any material additional costs or imposes material legal or regulatory burdens, nor which, in such Indemnified Party’s reasonable opinion, would have a material adverse effect on its business, operations or financial condition.

(e) If any Indemnified Party receives a refund of any Taxes as to which it has been indemnified pursuant to this Section 10.4 (including by the payment of additional amounts pursuant to this Section 10.4), it shall pay to the Seller an amount equal to such refund (but only to the extent of indemnity payments made under this Section 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). The Seller, upon the request of such Indemnified Party, shall repay to such Indemnified Party the amount paid over pursuant to this clause (e) (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 clause (e), in no event will the Indemnified Party be required to pay any amount to the Seller pursuant to this clause (e) 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 to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any Indemnified Party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the Seller or any other Person.

(f) If the Administrative Agent or any Purchaser is entitled to an exemption from or reduction of withholding or backup withholding tax (“Withholding Tax”) with respect to any payments under this Agreement it shall deliver to the Seller, Servicer or Administrative Agent, prior to the Monthly Payment Date and as otherwise prescribed by applicable law, such valid, properly completed and duly executed forms, certificates, and documentation (including Internal Revenue Service Form W-8ECI, W-8BEN, W-8IMY, or W-9 or successor form of the foregoing) prescribed by applicable law or reasonably requested by Seller, Servicer or Administrative Agent as will permit such payments to be made without or at a reduced rate of withholding. The Purchasers shall replace or update such forms when necessary to maintain any applicable exemption and as requested by the Administrative Agent or the Seller. The Purchasers agree to hold the Administrative Agent and the Seller harmless from any Withholding Taxes relating to payments by the Seller to the Purchaser or the Administrative Agent.

6

(g) If a payment made to a Purchaser, Servicer or Administrative Agent hereunder would be subject to U.S. federal Withholding Tax imposed by FATCA if such Purchaser, Servicer or Administrative Agent were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Internal Revenue Service Code, as applicable), such Purchaser, Servicer or Administrative Agent shall deliver to the Seller at the time or times prescribed by law and at such time or times reasonably requested by the Seller, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Service Code) and such additional documentation reasonably requested by the Seller as may be necessary for the Seller to comply with its obligations under FATCA and to determine that such Purchaser, Servicer or Administrative Agent has complied with such Purchaser, Servicer or Administrative Agent’s obligations under FATCA or to determine the amount to deduct and withhold from such payment.”

“(v) which by its terms is due and payable within 70 days of the original billing date therefor and has not had its payment terms extended, provided, however, that not more than 10.0% of the aggregate Outstanding Balance of all Receivables may have terms permitting payment to be made within 71-120 days of the original billing date therefor and still be “Eligible Receivables” so long as their payment terms have not been extended, provided, furthermore, that not more than 5.0% of the aggregate Outstanding Balance of all Receivables may have terms permitting payment to be made more than 120 days after the original billing date therefor and still be “Eligible Receivables” so long as their payment terms have not been extended,”
