in the Exhibits, Schedules and Annexes hereto refer to this Agreement, as amended, restated, supplemented or otherwise modified from time to time. 

3. In consideration of the mutual agreements, provisions and covenants contained herein, the parties hereto agree as follows: 

ARTICLE I 
 AMOUNTS AND
TERMS OF THE PURCHASES 
 Section 1.1. Purchase Facility. 

(a) On the terms and subject to the conditions hereof (including Section 1.2(c) below), the Seller may, in addition to each
Reinvestment (as described below) hereunder, from time to time before the Facility Termination Date, request that (x) the Conduit Purchasers ratably (based on the aggregate Commitments of the Committed Purchasers in their respective Purchaser
Groups) make Purchases (as described below), or (y) only if there is not a Conduit Purchaser in the applicable Purchaser Group or if a Conduit Purchaser (i) denies a request to purchase, or (ii) is otherwise unable or unwilling to
fund such Purchase (and provides written notice of such to the Seller, the Servicer, the Administrator and its Purchaser Agent), the Committed Purchasers ratably make purchases in the Purchased Interest from the Seller (each such purchase is
referred to herein as a “Purchase”). Each Committed Purchaser severally hereby agrees, on the terms and subject to the conditions hereof, to make Purchases of and Reinvestments from the Seller from time to time from the Closing Date
to (but excluding) the Facility Termination Date, based on the applicable Purchaser Group’s Group Commitment Percentage of each Purchase requested pursuant to Section 1.2(b) (and, in the case of each Committed Purchaser in a
Purchaser Group, its Commitment 

 
Percentage of such Purchaser Group’s Group Commitment Percentage of such Purchase). If at any time any Collections are received by the Servicer prior to the Facility Termination Date, the
Seller hereby requests and each Purchaser, as applicable, hereby agrees, subject to the terms and conditions set forth in this Agreement, to make, simultaneously with such receipt, a reinvestment purchase (each, a “Reinvestment”) in
additional Pool Receivables, the associated Related Security and Collections acquired by the Seller with each and every Collection received by the Servicer as and to the extent contemplated in Section 1.4(b) such that after giving effect
to such Reinvestment, the Aggregate Capital immediately after such receipt and corresponding Reinvestment shall be equal to the Aggregate Capital immediately prior to such receipt. 

(b) Under no circumstances shall any Purchaser make, any Purchase or Reinvestment if, after giving effect to such Purchase or Reinvestment
(i) any event has occurred and is continuing, or would result from such Purchase or Reinvestment, that constitutes a Termination Event or an Unmatured Termination Event; (ii) the outstanding Capital of such Purchaser, when added to all
other Capital of all other Purchasers in such Purchaser’s Purchaser Group outstanding at such time, would exceed its Purchaser Group’s Group Commitment; (iii) the Purchased Interest would exceed 100% or (iv) the Aggregate Capital
would exceed the Purchase Limit. 
 (c) The Seller may, upon at least 10 Business Days’ written notice to the Administrator and each
Purchaser Agent, terminate the purchase facility provided for in this Section in whole or, upon at least 10 Business Days’ written notice to the Administrator and each Purchaser Agent, from time to time, reduce in part the unused portion of the
Purchase Limit (but not below the amount that would cause the Aggregate Capital to exceed the Purchase Limit or would cause the aggregate outstanding Capital of any Purchaser Group to exceed its Group Commitment, in either case, after giving effect
to such reduction); provided, that (i) each partial reduction shall be in the amount of at least $5,000,000, or an integral multiple of $1,000,000 in excess thereof, (ii) unless terminated in whole, the Purchase Limit shall in no
event be reduced below $100,000,000 and (iii) such reduction shall be irrevocable and apply to such Period and each subsequent Period unless (A) such reduction occurs during Period 4, (B) such reduction reduces the FacilityPurchase Limit to an amount not less than $350,000,000 and (C) the related notice specifies that such reduction is only applicable to Period 4; provided, that only one such reduction may be requested in any
Period 4 and such reduction shall be irrevocable for such existing Period 4. In connection with each such reduction of the Purchase Limit, the Commitment of each Committed Purchaser and the Group Commitment of each Purchaser Group shall
automatically be ratably reduced by a proportionate amount. The Administrator shall advise the Purchaser Agents of any notice received by it pursuant to this Section 1.1(c); it being understood and agreed that no such termination of the
purchase facility provided hereunder shall be effective unless and until (i) the Aggregate Capital is reduced to zero and (ii) all other amounts then owed to the Administrator, the Purchaser Agents and the Purchasers under the Transaction
Documents have been paid in full. 
 Section 1.2. Making Purchases. 

(a) Rebalancing of Commitment Percentages. On each Settlement Date on which the Commitment Percentages of any Purchasers change in
connection with the start of a new Period as set forth on Schedule VI (or, in the case of the commencement of the Period 1 occurring in 2020, on July 13, 2020), the Seller shall be deemed to have requested a non-ratable reduction of
Capital from each Assigning Purchaser and a non-ratable Purchase from each Assignee Purchaser, in 

  
 -2- 

 
amounts with respect to each Assigning Purchaser and Assignee Purchaser, as applicable, such that, after giving effect to such reductions and Purchases, the outstanding aggregate Capital of each
Purchaser Group shall be equal to such Purchaser Group’s Group Commitment Percentage (after giving effect to the adjustments set forth on Schedule VI of this Agreement, as applicable) times the Aggregate Capital. For administrative
convenience, the Seller may instruct Assignee Purchasers to fund the foregoing Purchases by paying the proceeds thereof directly to the Assigning Purchasers as the foregoing reduction in Capital of the Assigning Purchasers on the Seller’s
behalf and such Assignee Purchasers shall fund such rebalancing Purchases to the Assigning Purchasers regardless of whether the conditions precedent to a Purchase set forth in Exhibit II or otherwise in this Agreement are satisfied. For purposes of
this paragraph the following terms shall have the following meanings: 
 “Assignee Purchaser” means a
Purchaser whose Group Commitment Percentage (after giving effect to such adjustments occurring on such Settlement Date, as applicable) times the Aggregate Capital exceeds the outstanding aggregate Capital of such Purchaser Group at such time. 

“Assigning Purchaser” means a Purchaser whose Group Commitment Percentage (after giving effect to such
adjustments occurring on such Settlement Date, as applicable) times the Aggregate Capital is less than the outstanding aggregate Capital of such Purchaser Group at such time. 

(b) Each Purchase (but not Reinvestment) of Receivables hereunder shall be made on the requested Purchase date upon the Seller’s
irrevocable written notice in the form of Annex B (the “Purchase Notice”) delivered to the Administrator and each Purchaser Agent in accordance with Section 7.2 by 2:00 p.m., New York, New York time, at least one
Business Day before the requested Purchase date, which notice shall specify: (i) the amount requested to be paid to the Seller (such amount, which shall not be less than $1,000,000 and shall be in integral multiples of $100,000 in excess
thereof) with respect to each Purchaser Group in connection with such Purchase; (ii) the date of such Purchase; and (iii) the pro forma calculation of the Purchased Interest after giving effect to the increase in Aggregate Capital
resulting from such Purchase. 
 (c) On the date of each Purchase (but not Reinvestment) hereunder, each applicable Conduit Purchaser or
Committed Purchaser, as the case may be in accordance with Section 1.1(a), shall, upon satisfaction of the applicable conditions set forth in Exhibit II, make available to the Seller in same day funds, at the account designated in
writing by the Seller to the Administrator and each Purchaser Agent, an amount equal to the portion of Capital to be funded by such Purchaser (as determined in accordance with Sections 1.1(a) and 1.2(b)). 

(d) Effective on the date of each Purchase pursuant to this Section 1.2 and each Reinvestment pursuant to Section 1.4,
the Seller hereby sells and assigns to the Administrator for the benefit of the Purchasers (ratably, based on the Purchasers’ respective outstanding Capital at such time after giving effect to such Purchase) an undivided percentage ownership
interest in: (i) each Pool Receivable then existing, (ii) all Related Security with respect to such Pool Receivables, and (iii) all Collections with respect to, and other proceeds of, such Pool Receivables and Related Security. 

  
 -3- 

 (e) It is the intention of the parties to this Agreement that the conveyance of
Seller’s right, title and interest in the Pool Receivables, all Related Security with respect to such Pool Receivables and all Collections with respect to such Pool Receivables to the Administrator on behalf of the Purchasers pursuant to this
Agreement shall constitute a purchase and sale and not a pledge, and such purchase and sale of such Pool Receivables, Related Security and Collections to the Administrator on behalf of the Purchasers, hereunder shall be treated as a sale for all
purposes (other than for income tax purposes). If, notwithstanding the foregoing, the conveyance of Pool Receivables, Related Security and Collections to the Administrator on behalf of the Purchasers, is characterized by any Governmental Authority,
bankruptcy trustee or any other Person as a pledge or other security for indebtedness, the parties intend that Seller shall be deemed hereunder to have granted, and Seller does hereby grant, to the Administrator, on behalf of the Purchaser Groups,
to secure all of the Seller’s obligations (monetary or otherwise) under this Agreement and the other Transaction Documents to which it is a party, whether now or hereafter existing or arising, due or to become due, direct or indirect, absolute
or contingent, a security interest in all of the Seller’s right, title and interest in, to and under all of the following, whether now or hereafter owned, existing or arising: (i) each Pool Receivable; (ii) all Related Security;
(iii) all Collections; (iv) the Collection Accounts, the Concentration Account and, in each case, all amounts on deposit therein; (v) all rights (but none of the obligations) of the Seller under the Purchase and Sale Agreement; and
(vi) all products and proceeds of, and all amounts received or receivable under, any or all of the foregoing (collectively, the “Pool Assets”). In connection with each Purchase and Reinvestment and the grant of the security
interest in the Pool Assets set forth in this Section 1.2(e), the Seller hereby authorizes the filing by the Administrator of all applicable UCC financing statements and amendments thereto in all jurisdictions necessary to perfect (and
to continue the perfection of) the security interest created hereby, including, without limitation, any financing statement containing a collateral description of “all assets” or language similar thereto. Each of the parties hereto intends
that no Purchase hereunder shall constitute, or be deemed to constitute, a “security” under U.S. securities laws or within the meaning of the UCC. 

(f) Each Committed Purchaser’s obligations hereunder shall be several, such that the failure of any Committed Purchaser to make a payment
in connection with any Purchase hereunder, shall not relieve any other Committed Purchaser of its obligation hereunder to make payment for any Purchase. 

(g) The Seller may, at any time prior to a Termination Event, with the written consent of the Administrator (which consent may be at the
Administrator’s reasonable discretion), (i) add additional financial institutions as Purchasers (including by creating new Purchaser Groups) or (ii) cause an existing Purchaser to increase its Commitment in connection with a
corresponding increase in the Purchase Limit; provided, however, that the Commitment of any Purchaser may only be increased with the prior written consent of such Purchaser. Each new Purchaser (or Purchaser Group) shall become a party hereto, by
executing and delivering to the Administrator and the Seller, an Assumption Agreement in the form of Annex E hereto (which Assumption Agreement shall, in the case of any new Purchaser or Purchasers, be executed by each Person in such new
Purchaser’s Purchaser Group).

 Section 1.3. Purchase Interest Computation. The Purchased Interest shall be
initially computed on the date of the initial Purchase hereunder. Thereafter, until the Facility Termination Date, the Purchased Interest shall be automatically recomputed (or deemed to be recomputed) on each Business Day other than the Facility
Termination Date it being understood that the Servicer shall not ordinarily be required to provide evidence of such automatic recomputation except as provided in Section 2(a) of Exhibit II. With respect to each calculation of the
Purchased Interest, the Total Reserves used in such calculation shall be measured using the information reported in the most recent Information Package. On each Termination Day, the Purchased Interest shall be deemed to be 100%. The Purchased
Interest shall become zero on the Final Termination Date. 
 Section 1.4. Settlement Procedures. 

(a) The collection of the Pool Receivables shall be administered by the Servicer in accordance with this Agreement. The Seller shall provide to
the Servicer on a timely basis all information needed for such administration, including notice of the occurrence of the Facility Termination Date and current computations of the Purchased Interest (and the components thereof). 

(b) The Servicer shall, on each day on which Collections of Pool Receivables are received (or deemed received) by the Seller or the Servicer:

 (i) set aside and hold in trust (and shall, at the request of the Administrator after the occurrence of an Unmatured
Termination Event or Termination Event, segregate in a separate account approved by the Administrator) for the benefit of each Purchaser Group, out of such Collections, an amount equal to the sum of (w) the Aggregate Discount accrued through
such day for each portion of Capital not previously set aside, (x) an amount equal to the fees owing to the Purchasers and the Administrator accrued and unpaid through such day, and (y) all other amounts then due and payable by the Seller
under this Agreement to the Purchasers, the Purchaser Agents, the Administrator, and any other Indemnified Party or Affected Person; 

(ii) subject to Section 1.4(f), if such day is not a Termination Day, the remainder of the Collections not set
aside pursuant to clause (b)(i) of this Section 1.4 shall, to the extent representing a return of Capital, be automatically Reinvested according to each Purchaser’s Capital in Pool Receivables, and in the associated Related
Security, Collections and other proceeds with respect thereto; provided, however, that, if after giving effect to any such Reinvestment, (x) the Purchased Interest would exceed 100% or (y) the Aggregate Capital would exceed the Purchase
Limit then in effect, then the Servicer shall not so Reinvest, but shall set aside and hold in trust for the benefit of the Purchasers (and shall, at the request of the Administrator, segregate in a separate account approved by the Administrator) a
portion of such Collections that, together with the other Collections set aside pursuant to this paragraph, shall equal the amount necessary to (x) reduce the Purchased Interest to 100% and (y) cause the Aggregate Capital to not exceed the
Purchase Limit, as applicable, which amount shall be deposited ratably to each Purchaser Agent’s account (for the benefit of its related Purchasers and to be applied in reduction of their respective Capital) on the next Settlement Date in
accordance with Section 1.4(c); 

  
 -5- 

 (iii) if such day is a Termination Day, set aside, segregate and hold in
trust (and shall, at the request of the Administrator, segregate in a separate account approved by the Administrator), for the benefit of each Purchaser Group, the entire remainder of the Collections not set aside pursuant to clause (b)(i) of
this Section 1.4; provided, that if amounts are so set aside and held in trust on any Termination Day, then such previously set-aside amounts shall, to the extent representing a return on Capital, be Reinvested in accordance with
clause (ii) above on the next day to occur that is not a Termination Day (if any); and 
 (iv) release to the
Seller (subject to Section 1.4(f)) for its own account any Collections in excess of: (w) amounts required to be Reinvested in accordance with clause (ii) above plus (x) the amounts that are required to be set
aside pursuant to clause (i) above, pursuant to the proviso to clause (ii) above and pursuant to clause (iii) above, plus (y) the Seller’s Servicing Fees accrued and unpaid through such day. 

(c) On the fifth (5th) Business Day of each calendar month, each Purchaser Agent will notify the Servicer by electronic mail of the amount
of Discount accrued with respect to each portion of Capital during the previous Settlement Period. On each Settlement Date, the Servicer shall, in accordance with the priorities set forth in Section 1.4(d), deposit into the account
specified by each Purchaser Agent Collections held for such Purchaser Agent (for the benefit of its related Purchasers) pursuant to Section 1.4(b)(i) or 1.4(f) plus the amount of Collections then held for such Purchaser Agent (for
the benefit of its related Purchasers) pursuant to Sections 1.4(b)(ii) and 1.4(b)(iii); provided, however, that if the Information Package delivered by the Servicer indicates a Purchased Interest in excess of 100%, then the
amount of Collections not Reinvested pursuant to clause (b)(ii) shall be deposited into the account for each Purchaser maintained by the applicable Purchaser Agent as may be designated from time to time by such Purchaser Agent to the Seller
and the Servicer on the date such Information Package is received and on each day thereafter to the extent the Purchased Interest exceeds 100%. 

(d) The Servicer shall distribute the amounts described (and at the times set forth) in Section 1.4(c) on each Settlement Date as
follows: 
 (i) if such distribution occurs on a day that is not a Termination Day and the Purchased Interest does not exceed
100%: 
 first, to the Servicer, the Servicing Fee, to the extent accrued and unpaid through the last day of the
immediately preceding Settlement Period until such accrued fees are paid in full, to the extent not otherwise netted out from Collections by the Servicer; 

second, to the extent such amounts are then payable hereunder, to each Purchaser Agent (for the benefit of the
Purchasers within such Purchaser Agent’s Purchaser Group), in payment in full of, all accrued Discount with respect to each portion of Capital maintained by such Purchasers (it being understood that each Purchaser Agent shall distribute such
amounts to the Purchasers within its Purchaser Group ratably in accordance with each Purchaser’s Capital); 

third, ratably to the Purchaser Agents and the Administrator, all accrued fees (including program fees) owing to the
Purchasers (it being understood that each Purchaser Agent shall distribute such amounts to the Purchasers within its Purchaser Group ratably in accordance with each such Purchaser’s Capital) and to the Administrator; 

  
 -6- 

 fourth, if the Servicer has set aside amounts in respect of a
reduction of the Aggregate Capital pursuant to clause (f) below, to each Purchaser Agent (for the benefit of the Purchasers within such Purchaser Agent’s Purchaser Group), in payment in full of the related reduction in Aggregate
Capital; it being understood that each Purchaser Agent shall distribute such amounts to the Purchasers within its Purchaser Group ratably in accordance with each such Purchaser’s Capital; and 

fifth, to the Seller for its own account. 

(ii) if such distribution occurs on a Termination Day or on any day on which the Purchased Interest exceeds 100%: 

first, to the Servicer, the Servicing Fee, to the extent accrued and unpaid through the last day of the immediately
preceding Settlement Period until such accrued fees are paid in full, to the extent not otherwise netted out from Collections by the Servicer; 

second, to each Purchaser Agent (for the benefit of the Purchasers within such Purchaser Agent’s Purchaser Group),
in payment in full of, all accrued Discount with respect to each portion of Capital maintained by such Purchasers (it being understood that each Purchaser Agent shall distribute such amounts to the Purchasers within its Purchaser Group ratably in
accordance with each Purchaser’s Capital); 
 third, ratably to the Purchaser Agents and the Administrator, such
accrued fees owing to the Purchasers (it being understood that each Purchaser Agent shall distribute such amounts to the Purchasers within its Purchaser Group ratably in accordance with each Purchaser’s Capital) and to the Administrator; 

fourth, to each Purchaser Agent (for the benefit of the Purchasers within such Purchaser Agent’s Purchaser Group),
in payment in full of each Purchaser’s Capital (or if such day is not a Termination Day but is a day on which the Purchased Interest exceeds 100%, the amount necessary to reduce the Purchased Interest to 100%) it being understood that each
Purchaser Agent shall distribute such amounts to the Purchasers within its Purchaser Group ratably in accordance with each Purchaser’s Capital; 

fifth, if the Aggregate Capital and accrued Aggregate Discount and fees with respect thereto have been reduced to zero
(or the Aggregate Capital has been reduced to the extent necessary to cause the Purchased Interest not to exceed 100%), and all accrued Servicing Fees payable to the Servicer have been paid in full, to the Purchasers, the Administrator and any other
Indemnified Party or Affected Person in payment in full of any other Aggregate Unpaids owed thereto by the Seller hereunder (other than contingent indemnification obligations);
and 

  
 -7- 

sixth, to pay all outstanding amounts owing under the Company Note; and  

sixthseventh, to the Seller for its own account. 

(e) For the purposes of this Section 1.4: 

(i) if on any day the Outstanding Balance of any Pool Receivable is reduced or canceled as a result of (x) without
duplication, any revision, cancellation, allowance, rebate, dilution, discount, or other adjustment (including, without limitation, an extension or adjustment made pursuant to the applicable Credit and Collection Guidelines) made by the Seller, the
Servicer or any Originator, including in connection with the cancellation and reissuance of any Pool Receivable, or (y) any set-off or dispute between the Seller or any Originator and an Obligor (any such reduction or cancellation, a
“Dilution”), in any such case, the Seller shall be deemed to have received on such day a Collection of such Pool Receivable in the amount of such reduction, adjustment, cancellation or dispute (which, in the case of a cancellation
and reissuance of any Pool Receivable, shall be an amount equal to the full Outstanding Balance of the cancelled Pool Receivable) and shall, subject to Section 1.4(e)(v), (x) if such day is not a Termination Day, hold any and all
such amounts in trust for the benefit of each Purchaser Group and, on the following Settlement Date, apply such amounts in accordance with this Section 1.4 or (y) if such day is a Termination Day, within two (2) Business Days
of such reduction or adjustment, pay from its own funds any and all such amounts in respect thereof to a Collection Account or the Concentration Account for the benefit of each Purchaser Group and for application pursuant to this
Section 1.4; 
 (ii) if on any day any of the representations or warranties in Section 1(g) or
(n) of Exhibit III is not true with respect to any Pool Receivable a Collection of the full Outstanding Balance of such Pool Receivable, the Seller shall, subject to Section 1.4(e)(v), (1) if such day is not a
Termination Day, hold any and all such amounts in trust for the benefit of each Purchaser Group and, on the following Settlement Date, apply such amounts in accordance with this Section 1.4 or (2) if such day is a Termination Day,
within two (2) Business Days, pay any and all such amounts from its own funds in respect thereof to a Collection Account or the Concentration Account for the benefit of each Purchaser Group and for application pursuant to this
Section 1.4 (Collections deemed to have been received pursuant to Sections 1.4(e)(i) or (ii) are hereinafter sometimes referred to as “Deemed Collections”); 

(iii) except as provided in clause (i) or (ii), or as otherwise required by applicable Law, all Collections
received from an Obligor of any Pool Receivable shall be applied to the Pool Receivables of such Obligor in the order of the age of such Receivables, starting with the oldest such Receivable, unless such Obligor designates its payment for
application to specific Receivables; 
 (iv) if and to the extent the Administrator or any Purchaser shall be required for
any reason to pay over to an Obligor (or any trustee, receiver, custodian or similar official in any Insolvency Proceeding) any amount received by it hereunder, such amount shall be deemed not to have been so received by the Administrator or such
Purchaser but rather to have been retained by the Seller and, accordingly, the Administrator or such Purchaser, as the case may be, shall have a claim against the Seller for such amount, payable when and to the extent that any distribution from or
on behalf of such Obligor is made in respect thereof; 

  
 -8- 

 (v) if at any time before the Facility Termination Date the Seller is deemed
to have received any Deemed Collection under Sections 1.4(e)(i) or (ii), so long as no Termination Day then exists, the Seller may satisfy its obligation to deliver the amount of such Deemed Collections to a Collection Account or
the Concentration Account by instead recalculating (or being deemed to have recalculated) the Purchased Interest by decreasing the Net Receivables Pool Balance by the amount of such Deemed Collections, so long as such adjustment does not cause the
Purchased Interest to exceed 100%; and 
 (vi) if at any time the Seller satisfies in full its obligations hereunder with
respect to Deemed Collections (whether by payment to a Collection Account or the Concentration Account and/or by reducing the Net Receivables Pool Balance), the Administrator, on behalf of the Purchasers, shall re-convey to the Seller the Pool
Receivable(s) to which such Deemed Collection relates, without recourse and without any representation or warranty except that such Pool Receivable is free and clear of liens, security interests, charges and encumbrances created by the Administrator
or any such Purchaser, and thereafter the Seller shall not sell any interest in such Receivable to the Administrator on behalf of the Purchasers. 

(f) At any time, the Seller may elect to cause a reduction of Capital in accordance with this clause (f). The Seller may do so as
follows: 
 (i) the Seller shall deliver to the Administrator, each Purchaser Agent and the Servicer written notice in
substantially the form of Annex C (the “Paydown Notice”) at least two Business Days’ prior to the date of such reduction for any reduction of Aggregate Capital, which notice shall include the amount of such proposed
reduction and the proposed date on which such reduction will commence; 
 (ii) on the proposed date of the commencement of
such reduction and on each day thereafter, the Servicer shall cause Collections not to be Reinvested until the amount thereof not so Reinvested shall equal the desired amount of the reduction of Aggregate Capital; and 

(iii) the Servicer shall hold (or cause the Seller to set aside and hold) such Collections in trust for each Purchaser, for
payment to each Purchaser Agent for the benefit of such Purchaser on the next Settlement Date, and the Aggregate Capital shall be deemed reduced in the amount to be paid to a Purchaser Agent only when in fact finally so paid; 

provided, that (x) the amount of any such reduction (if not a reduction to zero) shall be not less than $1,000,000 and shall be an integral
multiple of $100,000, and the entire Aggregate Capital after giving effect to such reduction shall be not less than $10,000,000 (unless the entire Aggregate Capital shall have been reduced to zero); and (y) the Seller shall choose a reduction
amount, and the date of commencement thereof, so that to the extent practicable such reduction shall commence and conclude in the same Settlement Period.

 Section 1.5. Fees. (a) The Seller shall pay to each Purchaser Agent for the
benefit of the Purchasers in the related Purchaser Group in accordance with the provisions set forth in Section 1.4(d) certain fees in the amounts and on the dates set forth in that certain fee letter agreement, dated the Closing Date

designated from time to time by such Purchaser Agent to the Seller and the Servicer. All amounts received after 1:00 p.m. (New York, New York time) will be deemed to have been received on the next Business Day. Except as expressly set forth herein,
each Purchaser Agent shall distribute the amounts paid to it hereunder for the benefit of the Purchasers in its Purchaser Group to the Purchasers within its Purchaser Group ratably (x) in the case of such amounts paid in respect of Discount and
fees, according to the Discount and fees payable to such Purchasers and (y) in the case of such amounts paid in respect of Capital (or in respect of any other obligations other than Discount and fees), according to the outstanding Capital
funded by such Purchasers. 
 (b) The Seller (with respect to amounts payable by the Seller) or the Servicer (with respect to amounts payable
by the Servicer), as the case may be, shall, to the extent permitted by law, pay interest on any amount not paid or deposited by the Seller or the Servicer, as the case may be, when due and payable hereunder, at an interest rate equal to
2.00% per annum above the Base Rate, payable on demand; provided, that such rate shall not at any time exceed the maximum rate permitted by applicable Law. 

(c) All computations of interest under clause (b) and all computations of Discount, fees and other amounts hereunder shall be made
on the basis of a year of 360 days (or 365 or 366 days, as applicable, with respect to Discount or other amounts calculated by reference to the Base Rate) for the actual number of days elapsed. Whenever any payment or deposit to be made hereunder

 Section 1.7. Increased Costs. 

(a) Generally. If (A) the adoption after the date hereof of any Regulatory Change or any change therein after the date hereof,
(B) any change after the date hereof in the interpretation or administration of any Regulatory Change by any Governmental Authority charged with the interpretation or administration thereof, or compliance with any request or directive (whether
or not having the force of law) of any such Governmental Authority, or (c) without regard to the date of adoption, effectiveness or implementation, any of the following or any Regulatory Change promulgated by any Governmental Authority in
connection with any of the following: (x) the Dodd-Frank Wall Street Reform and Consumer Protection Act, or (y) any accord or other pronouncement of the Bank for International Settlements, the Basel Committee on Banking Supervision or any
successor or similar authority, shall: 
 (i) subject any Affected Person to any Tax or other charge with respect to any
Specified Matter, or shall change the basis of taxation of payments to any Affected Person of amounts payable under or otherwise in respect of any Specified Matter (other than (A) Indemnified Taxes, (B) Taxes described in clauses
(b) through (d) of the definition of Excluded Taxes and (C) Other Connection Taxes that are imposed on or measured by net income (however denominated) or that are franchise Taxes or branch profits Taxes); 

(ii) impose, modify or deem applicable any reserve, assessment, fee, insurance charge, special deposit, requirement for the
maintenance of assets or capital, liquidity or similar requirement against assets of, deposits with or for the account of, liabilities of or credit extended by, any Affected Person or shall impose on any Affected Person or on the United States
market for commercial paper or the London interbank market any other condition affecting or otherwise in respect of any Specified Matter; or 

(iii) impose any other condition the result of which is to increase the cost to an Affected Person of performing its
obligations under or in connection with this Agreement, or to reduce the rate of return on Affected Person’s capital or assets as a consequence of its obligations under or in connection with this Agreement, or to reduce the amount of any sum
received or receivable by an Affected Person, or to require any payment calculated by reference to the amount of interests or loans held or interest received by it, 

then, promptly following demand by such Affected Person through the Administrator, the Seller shall pay to the Administrator for the benefit
of such Affected Person, such additional amount or amounts as will compensate such Affected Person for such Tax, increased cost or reduction. Notwithstanding the foregoing, no Affected Person shall be entitled to request or receive any such
additional amounts for any Tax, increased cost or reduction unless such Affected Person is otherwise generally requesting similar additional amounts from other similarly situated Persons under facilities similar to the facility provided by this
Agreement. 
 (b) Adoption of Regulatory Changes. The Seller acknowledges that any Affected Person may institute measures in
anticipation of a Regulatory Change (including, without limitation, the imposition of internal charges on such Affected Person’s interests or obligations under any Transaction Document or Program Support Agreement), and may commence allocating
charges to or seeking compensation from the Seller under this Section 1.7 in connection with such measures, in advance of the effective date of such Regulatory Change, and the Seller agrees to pay such charges or compensation to such
Affected Person, following demand therefor in accordance 

  
 -11- 

 
with the terms of this Section 1.7, without regard to whether such effective date has occurred. Notwithstanding the foregoing, no Affected Person may allocate charges or seek
compensation under this Section 1.7(b) unless such Affected Person is generally allocating similar charges or seeking similar compensation from other similarly situated Persons under facilities similar to the facility provided by this
Agreement. 
 (c) Delay in Requests. Failure or delay on the part of any Affected Person to demand compensation pursuant to this
Section shall not constitute a waiver of such Affected Person’s right to demand such compensation; provided that the Seller shall not be required to compensate an Affected Person pursuant to this Section for any increased costs incurred
or reductions suffered more than 180 days prior to the date that such Affected Person notifies the Seller of the Regulatory Change giving rise to such increased costs or reductions and of such Affected Person’s intention to claim compensation
therefor (except that, if the Regulatory Change giving rise to such increased costs or reductions is retroactive, then the 180 day period referred to above shall be extended to include the period of retroactive effect thereof). 

Section 1.8. Selection and Allocation of Discount Rates. Subject to the requirements set forth in this Agreement, the
Administrator and the Purchaser Agents shall from time to time, only for purposes of computing Discount with respect to each Purchaser, account for such Purchaser’s portion of Capital in terms of one or more portions (or tranches), and the
applicable Discount Rate may be different for each portion of Capital. Each Purchaser’s Capital shall be allocated to each portion of Capital by the Administrator or the applicable Purchaser Agent to reflect the funding sources for each such
portion of such Capital, so that: 
 (a) there will be a Discount Rate for the portion of Capital funded or maintained through the issuance
of Commercial Paper Notes; and 
 (b) there will be a Discount Rate for the portion of Capital, if any, not funded or maintained through the
issuance of Commercial Paper Notes (including by outstanding Liquidity Advances or by funding under any Program Support Agreement). 

Section 1.9. Inability to Determine Rates; Changes in Legality. 

(a) If any Purchaser Agent shall have determined (which determination shall be conclusive and binding upon the parties hereto) before the first
day of any Settlement Period, by reason of circumstances affecting the interbank Eurodollar market, either that: (i) dollar deposits in the relevant amounts and for the relevant Settlement Period or day, as applicable, are not available,
(ii) adequate and reasonable means do not exist for ascertaining the LIBO Rate for such Settlement Period or day, as applicable, or (iii) the LIBO Rate determined pursuant hereto does not accurately reflect the cost to the applicable
Affected Person (as conclusively determined by such Purchaser Agent) of maintaining any portion of Capital during such Settlement Period or day, as applicable, such Purchaser Agent shall promptly give telephonic notice of such determination,
confirmed in writing, to the Seller before the first day of any Settlement Period. Upon delivery of such notice: (i) no portion of Capital shall be funded thereafter at the Base Rate determined by reference to the LIBO Rate unless and until
such Purchaser Agent shall have given notice to the Seller that the circumstances giving rise to such determination no longer exist, and (ii) with respect to any outstanding portion of Capital then funded at the Base Rate determined by
reference to the LIBO Rate, such Base Rate shall automatically be converted to the Base Rate determined without reference to the LIBO Rate on the last day of the then-current Settlement Period. 

  
 -12- 

 (b) If, on or before the first day of any Settlement Period, any Purchaser Agent shall have
been notified by any Affected Person that such Affected Person has determined (which determination shall be final and conclusive) that any Regulatory Change, or compliance by such Affected Person with any Regulatory Change, shall make it unlawful or
impossible for such Affected Person to fund or maintain any portion of Capital at or by reference to the LIBO Rate, such Purchaser Agent shall notify the Seller, the Administrator and each other Purchaser Agent thereof. Upon receipt of such notice,
until the applicable Purchaser Agent notifies the Seller, the Administrator and each other Purchaser Agent that the circumstances giving rise to such determination no longer apply, (i) no portion of Capital shall be funded at or by reference to
the LIBO Rate and (ii) the Discount for any outstanding portions of Capital then funded at the Base Rate determined by reference to the LIBO Rate shall be converted to the Base Rate determined without reference to the LIBO Rate either
(x) on the last day of the then-current Settlement Period, only if such Affected Person may lawfully continue to maintain such portion of Capital at or by reference to the LIBO Rate prior to such conversion, or (y) immediately, if such
Affected Person may not lawfully continue to maintain such portion of Capital at or by reference to the LIBO Rate during such period. 

Section 1.10. Successor LIBO Rate. 

(a) If the Administrator determines (which determination shall be conclusive absent manifest error) that (i) the circumstances set forth
in Section 1.9(a) have arisen and are unlikely to be temporary or (ii) the circumstances set forth in Section 1.9(a) have not arisen but either (A) the administrator of the LIBO Rate has made a public statement
identifying a specific date after which the LIBO Rate will permanently or indefinitely cease to be published by it, (B) a rate other than the LIBO Rate has become a widely recognized benchmark rate for newly originated loans in Dollars in the
U.S. market, or (C) the administrator of the LIBO Rate or a Governmental Authority having jurisdiction over the Administrator has made a public statement identifying a specific a date after which the LIBO Rate may no longer be used for
determining interest rates for loans (any such date, a “LIBOR Termination Date”), then the Administrator and the Seller shall endeavor in good faith to establish a replacement index for the LIBO Rate and make adjustments to
applicable margins and related amendments to this Agreement as referred to below such that, to the extent practicable, the all-in Discount based on the replacement index will be substantially equivalent to the all-in LIBO Rate-based Discount in
effect prior to its replacement.
 (b) The Administrator and the Seller shall enter into an amendment to this Agreement to reflect the
replacement index, the adjusted margins and such other related amendments as may be appropriate, in the discretion of the Administrator, for the implementation and administration of the replacement index-based rate. Notwithstanding anything to
the contrary in this Agreement or the Transaction Documents (including, without limitation, Section 7.1, such amendment shall become effective without any further action or consent of any other party to this Agreement at 5:00 p.m. on the
fifth (5th) Business Day after the date a draft of the amendment is provided to the Purchaser Agents, unless the Administrator receives, on or before such fifth (5th) Business Day, a written notice from the Majority Purchaser Agents
stating that such Majority Purchaser Agents object to such amendment. 

  
 -13- 

 (c) Selection of the replacement index, adjustments to the applicable margins, and
amendments to this Agreement (i) will be determined with due consideration to the then prevailing market practices for determining and implementing a rate of interest for newly originated loans in the United States and loans converted from a
LIBO Rate-based rate to a replacement index-based rate, and (ii) may also reflect adjustments to account for (x) the effects of the transition from the LIBO Rate to the replacement index and (y) yield- or risk-based differences
between the LIBO Rate and the replacement index. 
 (d) Until an amendment reflecting a new replacement index in accordance with this
Section is effective, each advance, conversion and renewal of portion of Capital accruing Discount by reference to the LIBO Rate will continue to accrue Discount by reference to the LIBO Rate; provided however, that if the
Administrator determines (which determination shall be conclusive absent manifest error) that a LIBOR Termination Date has occurred, then following the LIBOR Termination Date, all portions of Capital accruing Discount by reference to the LIBO Rate
shall automatically begin accruing Discount by reference to the Base Rate until such time as an amendment reflecting a replacement index and related matters as described above is implemented. 

(e) Notwithstanding anything to the contrary contained herein, if at any time the replacement index is less than zero, at such times, such
index shall be deemed to be zero for purposes of this Agreement.

Purchaser, any Liquidity Provider, any other Program Support Provider, the Program Administrator or any of their respective Affiliates, agents, employees, officers, and directors (each, an “Indemnified Party”) may have hereunder or
under applicable Law, the Seller hereby agrees to indemnify each Indemnified Party and hold each Indemnified Party harmless from and against any and all claims, damages, expenses, costs, losses and liabilities, including Attorney Costs (all of the

Net Receivables Pool Balance as an Eligible Receivables to be an Eligible Receivable as of the date of such calculation, the failure of any information contained in any Information Package to be true and correct, or the failure of any other

 (v) any commingling of funds to which the Administrator, any Purchaser
Agent or any Purchaser is entitled hereunder with any other funds; 
 (vi) any dispute, claim, offset or defense (other than
discharge in bankruptcy of the Obligor) of the Obligor to the payment of any Receivable in, or purporting to be in, the Receivables Pool (including a defense based on such Receivable or the related Contract not being a legal, valid and binding
obligation of such Obligor enforceable against it in accordance with its terms), or any other claim resulting from the sale of the goods or services related to such Receivable or the furnishing or failure to furnish such goods or services or
relating to collection activities with respect to such Receivable or any Contract related thereto (if such collection activities were performed by the Seller or any of its Affiliates or by any agent or independent contractor retained by the Seller
or any of its Affiliates); 
  

  
 -15- 

 (vii) any failure of the Seller to perform its duties or obligations in

 Section 3.2. Indemnities by the Servicer. Without limiting any other rights that
the Administrator, any Purchaser Agent, any Purchaser or any other Indemnified Party may have hereunder or under applicable Law, the Servicer hereby agrees to indemnify each Indemnified Party and hold each Indemnified Party harmless from and against
any and all Indemnified Amounts arising out of or resulting from a breach by the Servicer of any of its obligations or representations and warranties under this Agreement or any other Transaction Document except (a) to the extent resulting from
fraud, gross negligence or willful misconduct on the part of such Indemnified Party; (b) for which indemnification would constitute recourse (except as otherwise specifically provided in this Agreement to be paid by the Servicer hereunder) for
uncollectible Receivables; and (c) in respect of Taxes. Without limiting the foregoing, but subject to the exclusions set forth in the preceding sentence, the Seller shall pay within five (5) Business Days after written demand (which
demand shall be accompanied by documentation of the Indemnified Amounts, in reasonable detail) to each Indemnified Party any and all amounts necessary to indemnify such Indemnified Party from and against any and all Indemnified Amounts relating to
or resulting from any of the following: 
 (i) the failure of any information provided by or on behalf of the Servicer for
inclusion in any Information Package to be true and correct, or the failure of any other information required to be provided to such Indemnified Party by, or on behalf of, the Servicer to be true and correct; 

(ii) the failure of any representation, warranty or statement made or deemed made by the Servicer (or any of its officers)
under or in connection with this Agreement to have been true and correct as of the date made or deemed made; 
 (iii) the
failure by the Servicer to comply with any applicable law, rule or regulation with respect to any Pool Receivable or the related Contract; 

(iv) any dispute, claim, offset or defense of the Obligor to the payment of any Receivable in, or purporting to be in, the
Receivables Pool resulting from or related to the collection activities of the Servicer with respect to such Receivable; 

(v) the commingling by the Servicer of Collections at any time with other funds; or 

(vi) any failure to perform the Servicer’s duties or obligations in accordance with the provisions hereof or any other
Transaction Document to which it is a party. 
 Section 3.3. Indemnity for Taxes. (a) Any and all payments by or on account
of any obligation of the Seller hereunder shall be made without deduction or withholding for any Taxes, except as required by applicable Law. If any applicable Law 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) the applicable Affected
Person receives an amount equal to the sum it would have received had no such deduction or withholding been made. In addition, if the Seller is required to pay any Tax pursuant to paragraph 1(r) of Exhibit IV that is (i) related to any
payment by or on account of any obligation of the Seller hereunder and (ii) an Excluded Tax, the Seller shall be entitled to deduct the amount of such Tax paid from payments hereunder by the Seller. The Seller will indemnify each Affected
Person against any Indemnified Taxes (i) imposed on an Affected Person pursuant to a payment made from the Seller with respect of such Affected Person’s Purchases or Reinvestments or (ii) which arise otherwise by reason of the
execution, delivery, performance or enforcement of the Transaction Documents. 

  
 -17- 

 (b) Each Affected Person will promptly notify the Seller in writing of any event of which it
has knowledge, which will entitle such Affected Person to compensation pursuant to this Section 3.3; provided, however, that failure of any Affected Person to demand indemnification for any Indemnified Taxes shall
not constitute a waiver of such right to indemnification, except that the Seller shall not be required to indemnify an Affected Person for Taxes under this Section 3.3 unless such Affected Person notifies the Seller of such claim no
later than 180 days after such Affected Person has knowledge of such Taxes being imposed or arising. Any notice claiming compensation under this Section 3.3 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. The Seller shall be obligated to pay any claim for Indemnified Taxes within 10 days upon receipt of such written notice (other than Indemnified Taxes and expenses payable by
reason of the action or inaction of the applicable Affected Person); provided that if the Seller reasonably believes that such Taxes were not correctly or legally asserted, the Affected Person will use reasonable efforts to cooperate with the
Seller to obtain a refund of such Taxes (which shall be paid in accordance with Section 3.3(c)) so long as such efforts would not, in the sole determination of the Affected Person, result in any additional costs or expenses or be
otherwise disadvantageous to the Affected Person. 
 (c) If an Affected Person 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 by the Seller, it shall pay over such refund to the Seller (but only to the extent of indemnity payments made, or additional amounts paid, by the Seller under this
Section 3.3 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses of such Affected Person and without interest (other than any interest paid by the relevant Governmental Authority with respect to such
refund net of any applicable Taxes payable in respect of such interest); provided, that the Seller agrees to repay each such Affected Person, promptly after the request of such Affected Person, the amount paid over to the Seller (plus any
penalties, interest or other charges imposed by the relevant Governmental Authority) in the event such Affected Person is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary, in no event will any
Affected Person be required to pay any amount to the Seller the payment of which would place such Affected Person in a less favorable net after-Tax position than such Affected Person would have been in if the Taxes 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 Taxes had never been paid. This Section 3.3(c) shall not be construed to require
any Affected Person to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to the Seller or any other Person. 

(d) Each Affected Person agrees that it will use reasonable efforts to reduce or eliminate any claim for indemnity pursuant to this
Section 3.3 or compensation pursuant to Section 1.7 including, subject to applicable Law, a change in the funding office of such Affected Person; provided, however, that nothing contained herein shall obligate
any Affected Person to take any action that imposes on such Affected Person any unreimbursed additional costs or legal or regulatory burdens which such Affected Person reasonably considers material, nor which, in such Affected Person’s
reasonable opinion, would have an adverse effect on its business, operations or financial condition. 

  
 -18- 

 (e) If any Affected Person requests compensation under
Section 1.7, or if the Seller is required to pay any Indemnified Taxes or additional amounts to any Affected Person or any Governmental Authority for the account of any Affected Person pursuant to this
Section 3.3 and, in each case, such Affected Person has declined or is unable to designate a different lending office in accordance with Section 3.3(d) above, then the Seller may, at its sole
expense and effort, upon notice to such Affected Person and the Administrator, require such Affected Person to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by,
Section 7.3), all of its interests, rights (other than its existing rights to payments pursuant to Section 1.7 or this Section 3.3) and obligations under this Agreement
and the related Transaction Documents to a Person eligible to be a Purchasing Committed Purchaser under Section 7.3(b) that shall assume such obligations (which such Purchasing Committed Purchaser may be another Affected
Person, if an Affected Person accepts such assignment); provided that: 
 (i) such Affected Person shall have
received payment of an amount equal to the outstanding principal of its Commitment, accrued Discount thereon, accrued fees and all other amounts payable to it hereunder and under the other Transaction Documents from the assignee (to the extent of
such outstanding principal and accrued Discount and fees) or the Seller (in the case of all other amounts); 
 (ii) in the
case of any such assignment resulting from a claim for compensation under Section 1.7 or payments required to be made pursuant to this Section 3.3, such assignment will result in a reduction in such compensation or payments
thereafter; and; 
 (iii) such assignment does not conflict with applicable Law. 

An Affected Person shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Affected
Person or otherwise, the circumstances entitling the Seller to require such assignment and delegation cease to apply. 
 ARTICLE IV

 ADMINISTRATION AND COLLECTIONS 

Section 4.1. Appointment of the Servicer. 

(a) The servicing, administering and collection of the Pool Receivables shall be conducted by the Person so designated from time to time as the
Servicer in accordance with this Section. Until the Administrator gives notice to TXU (in accordance with this Section) of the designation of a new Servicer, TXU is hereby designated as, and hereby agrees to perform the duties and obligations of,
the Servicer pursuant to the terms hereof. During the continuance of a Termination Event, the Administrator may (and at the direction of the Majority Purchaser Agents, shall) designate as Servicer any Person (including itself) to succeed TXU or any
successor Servicer except for any Person that is a direct competitor of TXU, on the condition in each case that any such Person so designated shall agree to perform the duties and obligations of the Servicer pursuant to the terms hereof. 

(b) Upon the designation of a successor Servicer as set forth in clause (a), TXU agrees that it will terminate its activities as
Servicer hereunder in a manner that the Administrator determines will facilitate the transition of the performance of such activities to the new Servicer, and TXU shall cooperate with and assist such new Servicer. Such cooperation shall include
providing access to and transferring related records and permitting use by the new Servicer of all licenses, hardware or software necessary or desirable to collect the Pool Receivables and the Related Security, in each case unless prohibited by law
or any contract relating to any such license, hardware or software. 

  
 -19- 

 (c) TXU acknowledges that, in making their decision to execute and deliver this Agreement,
the Administrator, each Purchaser Agent and each Purchaser have relied on TXU’s agreement to act as Servicer hereunder. Accordingly, TXU agrees that it will not voluntarily resign as Servicer. 

(d) The Servicer may delegate its duties and obligations hereunder to any sub-servicer (each a “Sub-Servicer”);
provided, that, in each such delegation (i) the Servicer shall remain primarily liable for the performance of the duties and obligations so delegated; (ii) the Seller, the Administrator and each Purchaser Group shall have the right
to look solely to the Servicer for performance; (iii) unless such Sub-Servicer is a Utility that is providing invoicing services to an Originator, the terms of any agreement with any Sub-Servicer shall provide that such agreement shall
terminate upon the termination of the Servicer hereunder by giving notice of its desire to terminate such agreement to the Servicer (and the Servicer shall provide appropriate notice to each such Sub-Servicer) and (iv) unless such Sub-Servicer
is an Originator or a Utility that is providing invoicing services to an Originator, the Administrator shall have consented in writing in advance to such delegation. For the avoidance of doubt, this Section 4.1(d) shall not apply to any
Payment Processor, any third party collection agency collecting Defaulted Receivables or any other third party service provider assisting in the servicing of the Defaulted Receivables. 

Section 4.2. Duties of the Servicer. 

(a) The Servicer shall take or cause to be taken all such action as may be necessary to administer and collect each Pool Receivable from time
to time, all in accordance with this Agreement and all applicable laws, rules and regulations, with reasonable care and diligence, and in accordance with the Credit and Collection Guidelines. The Servicer shall set aside (or cause the Seller to set
aside and hold), for the accounts of the Seller and each Purchaser Group, the amount of the Collections to which each is entitled in accordance with Article I. The Servicer may, in accordance with the applicable Credit and Collection
Guidelines, extend the maturity of any Pool Receivable and extend the maturity or adjust the Outstanding Balance of any Defaulted Receivable as the Servicer may determine to be appropriate to maximize Collections thereof or as required under
applicable laws, rules or regulations or the applicable Contract; provided, that for the purposes of this Agreement, (i) such extension shall not change the number of days such Pool Receivable has remained unpaid from the date of the
original invoice (if a Retail Receivable) or the original due date (if a POR Receivable) related to such Pool Receivable unless such Pool Receivable has been cancelled and reissued with an appropriate Deemed Collection in an amount equal to the
Outstanding Balance of the cancelled Pool Receivable being recorded pursuant to Section 1.4(e)(i); and (ii) such extension or adjustment shall not alter the status of such Pool Receivable as a Delinquent Receivable or a Defaulted
Receivable or limit the rights of any Purchaser, Purchaser Agent or the Administrator under this Agreement. The Seller shall deliver to the Servicer and the Servicer shall hold for the benefit of the Seller and the Administrator (for the benefit of
each Purchaser Group), in accordance with their respective interests, all records and documents (including computer tapes or disks) with respect to each Pool Receivable. Notwithstanding anything to the contrary contained herein, after the Facility
Termination Date has been declared pursuant to Section 2.2, the Administrator may direct the Servicer (whether TXU or 

  
 -20- 

 
any other Person) to commence or settle any legal action to enforce the collection of any Pool Receivable or to foreclose upon or repossess Related Security. The Servicer shall have no liability
hereunder for following any such directions in good faith. In no event, however, shall the Servicer be entitled to make or authorize any Person to make the Administrator, any Purchaser Agent, any Purchaser or any other Affected Person a party to any
legal action without such Person’s, as the case may be, express prior written consent. 
 (b) The Servicer shall, as soon as practicable
following actual receipt of collected funds, turn over to the Seller the collections of any indebtedness that is not a Pool Receivable, less, if TXU or an Affiliate thereof is not the Servicer, all reasonable and appropriate out-of-pocket costs and
expenses of such Servicer of servicing, collecting and administering such collections. The Servicer, if other than TXU or an Affiliate thereof, shall, as soon as practicable upon demand, deliver to the Seller all records in its possession that
evidence or relate to any indebtedness that is not a Pool Receivable, and copies of records in its possession that evidence or relate to any indebtedness that is a Pool Receivable. 

(c) Unless terminated earlier in accordance with the terms of this Agreement, the Servicer’s obligations hereunder shall terminate on the
Final Termination Date. 
 After such termination, if TXU or Subsidiary thereof was not the Servicer on the date of such termination, the
Servicer shall promptly deliver to the Seller all books, records and related materials that any Originator or the Seller previously provided to the Servicer, or that have been obtained by the Servicer, in connection with this Agreement. 

Section 4.3. Lock-Box Arrangements. 

(a) On or prior to the Closing Date, the Seller shall have delivered to the Administrator a Lock-Box Agreement in respect of each Collection
Account and the Concentration Account identified on Schedule II as of the Closing Date and delivered an original counterpart thereof to the Administrator. The Lock-Box Agreements for the Collection Accounts and the Concentration Account shall
provide the Administrator with “control” within the meaning of Section 9-104 of the UCC over such Collection Accounts and Concentration Account. The Lock-Box Banks for the Collection Accounts (other than any Collection Account
receiving Collections (either directly or by transfer directly from a related Lock-Box) on a Receivable originated by Dynegy Energy Services, LLC or Dynegy Energy Services (East), LLC) shall be directed by the Servicer to sweep all available funds
therein on a daily basis to the Concentration Account. The Seller shall not, and shall not permit any other Person to, attempt to terminate such automatic sweep feature or attempt to close the Concentration Account or any Collection Account unless
the Collections directed to such Collection Account are redirected to another Collection Account subject to a Lock-Box Agreement. 
 (b) At
any time that a Termination Event is continuing, the Administrator may (and at the direction of the Majority Purchaser Agents, shall) give notice to each Lock-Box Bank that the Administrator is exercising its rights to exclusive control under the
Lock-Box Agreements with respect to the Collection Accounts and the Concentration Account (a “Lock-Box Agreement Activation Notice”). Each of the Seller and the Servicer hereby agrees that if the Administrator (either directly or at
the direction of the Majority Purchaser Agents) exercises its rights under a 

  
 -21- 

 
Lock-Box Agreement, the Administrator shall have exclusive control of the proceeds (including Collections) of all Pool Receivables and the Seller hereby further agrees to take any other action
that the Administrator may reasonably request in connection therewith. Any proceeds of Pool Receivables received by the Seller or the Servicer thereafter shall be sent immediately to, or as instructed by, the Administrator to a deposit account for
the benefit of the Purchasers. Any Collections received by the Administrator that pursuant to the terms of this Agreement are to be delivered to the Seller shall be held in trust for the Seller. 

(c) If at any time, a Lock-Box Bank has a short term unsecured debt rating lower than A-1 by Standard & Poor’s or P-1 by
Moody’s (each a “Low Ratings Lock-Box Bank”), the Administrator may (and at the direction of the Majority Purchaser Agents, shall) require that the Seller open new Collection Accounts and/or a new Concentration Account with a
new Lock-Box Bank having such ratings. Such establishment of new deposit accounts and the execution and delivery of appropriate Lock-Box Agreements shall be completed promptly but in any event no later than thirty (30) days following the
Administrator’s notice. If any Collection Account or the Concentration Account remains at the applicable Low Ratings Lock-Box Bank ninety (90) days after the Administrator’s delivery of such notice it shall cease to be eligible
Lock-Box Bank for all purposes hereunder (but the Administrator shall not be under any obligation to terminate any existing Lock-Box Agreements until such time as no Collections are received by such non-eligible bank). 

Section 4.4. Enforcement Rights. 

(a) At any time while a Termination Event exists or after the Facility Termination Date has been declared pursuant to Section 2.2:

 (i) the Administrator may instruct the Seller or the Servicer to give notice of the Purchaser Groups’ interest in the
Pool Receivables to each Obligor, which notice shall direct that payments be made directly to the Administrator or its designee (for the benefit of each Purchaser Group), and the Seller or the Servicer, as the case may be, shall give such notice at
the expense of the Seller or the Servicer, as the case may be; provided, that if the Seller or the Servicer, as the case may be, fails to so notify each Obligor within 30 days after receipt of such instruction, the Administrator (at the
Seller’s or the Servicer’s, as the case may be, expense) may so notify the Obligors; 
 (ii) the Administrator may
request the Servicer to, and upon such request the Servicer shall (A) assemble all of the records necessary or desirable to collect the Pool Receivables and the Related Security, and transfer or license (to the extent permitted under applicable
contracts) to a successor Servicer the use of all software necessary or desirable to collect the Pool Receivables and the Related Security, and make the same available to the Administrator or its designee (for the benefit of each Purchaser Group) at
a place selected by the Administrator; and (B) segregate all cash, checks and other instruments received by it from time to time constituting Collections in a manner acceptable to the Administrator and, promptly upon receipt, remit all such
cash, checks and instruments, duly endorsed or with duly executed instruments of transfer, to the Administrator or its designee; and 

  
 -22- 

 (iii) the Seller and the Servicer shall enforce any and all covenants and
obligations of each Originator contained in the Purchase and Sale Agreement or any other Transaction Document as shall be instructed by the Administrator. 

(b) Each of the Seller and the Servicer hereby authorizes the Administrator (for the benefit of each Purchaser Group), and irrevocably appoints
the Administrator (for the benefit of each Purchaser Group) as its attorney-in-fact with full power of substitution and with full authority in the place and stead of the Seller or the Servicer, as applicable, which appointment is coupled with an
interest, to take any and all steps in the name of the Seller or the Servicer, as applicable, and on behalf of the Seller or the Servicer, as applicable, as may be necessary or desirable, in the reasonable determination of the Administrator to
collect any and all amounts or portions thereof due under any and all Pool Assets, including endorsing the name of the Seller or the Servicer, as applicable, on all checks and other instruments representing Collections and enforcing such Pool
Assets. Notwithstanding anything to the contrary contained in this subsection, none of the powers conferred upon such attorney-in-fact pursuant to the preceding sentence shall subject such attorney- in- fact to any liability if any action taken by
it shall prove to be inadequate or invalid, nor shall they confer any obligations upon such attorney-in-fact in any manner whatsoever. The Administrator shall only be entitled to act as contemplated in this clause (b) while a Termination
Event exists or after the Facility Termination Date has been declared pursuant to Section 2.2. 
 Section 4.5.
Responsibilities of the Servicer. 
 (a) Anything herein to the contrary notwithstanding, the Servicer shall (or shall cause the
applicable Originator to): (i) perform all of its obligations, if any, under the Contracts related to the Pool Receivables to the same extent as if interests in such Pool Receivables had not been transferred to the Seller or the Purchasers
hereunder, and the exercise by the Administrator, the Purchaser Agents or the Purchasers of their respective rights hereunder shall not relieve the Servicer from such obligations; and (ii) pay out of Collections or other cash owned by the
Seller, on behalf of the Seller (or cause the Seller to pay) when due any taxes, energy surcharges and other governmental charges payable by the Seller, if any, in connection with any of the Pool Receivables or this Agreement. None of the
Administrator, the Purchaser Agents and the Purchasers shall have any obligation or liability with respect to any Pool Asset, nor shall any of them be obligated to perform any of the obligations of the Seller, the Servicer or any Originator
thereunder. 
 (b) TXU hereby irrevocably agrees that if at any time it shall cease to be the Servicer hereunder, it shall act (if the
then-current Servicer so requests) as the data-processing agent of the then-current Servicer and, in such capacity, TXU shall conduct the data-processing functions of the administration of the Pool Receivables and the Collections thereon in
substantially the same way that TXU conducted such data-processing functions while it acted as the Servicer. So long as it is acting as the Servicer, as consideration for performing such services, the Servicer shall be entitled to a portion of the
Servicing Fee equal to the portion of the servicing duties that TXU continues to perform. 
 Section 4.6. Servicing Fee. 

The Servicer shall, on each day, be paid a fee daily in arrears, as contemplated in Section 1.4, equal to the product of
(i) 1.00% per annum (the “Servicing Fee Rate”), (ii) the aggregate Outstanding Balance of the Pool Receivables as of the start of the day immediately preceding such day, and (iii) a fraction, the
numerator of which is 1 and the denominator of which is 360.

 ARTICLE V 

PERFORMANCE GUARANTY 

Section 5.1. Guaranty. The Performance Guarantor hereby unconditionally guarantees the punctual payment and performance when due,
whether at stated maturity, by acceleration or otherwise, of all obligations of the Servicer and each Originator in all capacities in which any such party acts under the Transaction Documents, now or hereafter existing under the Transaction
Documents (such obligations being the “Obligations”), and agrees to pay any and all reasonable and properly documented out-of-pocket expenses (including Attorney Costs) in enforcing any rights under this Performance Guaranty,
together with interest on such expenses (from the time when such amounts were incurred, based on a 365-day year) at a rate per annum for each day equal to the Base Rate on such day plus 2.00%. Without limiting
the generality of the foregoing, the Performance Guarantor’s liability shall extend to all amounts which constitute part of the Obligations and would be owed by any Person to the Seller or any Beneficiary under any Transaction Document but for
the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such Person as debtor. Notwithstanding anything to the contrary herein, the liability of the Performance
Guarantor under this Performance Guaranty with respect to the Obligations is (a) limited to, and shall in no event or under any circumstances, exceed the lesser
of (i) $385,000,000 (which is110% of the
Purchase Limit on the Closing Date plus ten percent) in the aggregate and (ii) if the Purchase Limit has been reduced by the Seller in accordance with
Section 1.1(c), an amount equal to the
reduced Purchase Limit plus ten percent, in each
casein effect from time to time, inclusive of all
interest, charges, fees, expenses or otherwise but exclusive of any and all out-of-pocket expenses arising from enforcement of such Performance Guaranty (the reimbursement of which not being subject to such limitation) and (b) subject to
termination on the Final Termination Date. Expiry of this Performance Guaranty shall not reduce or diminish the liability of the Performance Guarantor to the Beneficiaries in respect of any Obligation incurred on before the Facility Termination
Date. For the avoidance of doubt, the obligations of the Performance Guarantor under this Performance Guaranty do not include losses in respect of Receivables that are uncollectible on account of the insolvency, bankruptcy or lack of
creditworthiness of the Obligor. 
 Section 5.2. Guaranty Absolute. The Performance Guarantor guarantees that the
Obligations will be performed or paid strictly in accordance with the terms of the applicable Transaction Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights
of any Beneficiary with respect thereto. The obligations of the Performance Guarantor under this Performance Guaranty are independent of the Obligations, and a separate action or actions may be brought and prosecuted against the Performance
Guarantor to enforce this Performance Guaranty, irrespective of whether any action is brought against the Servicer or any Originator or whether the Servicer or such Originator is joined in any such action or actions. The liability of the Performance
Guarantor under this Performance Guaranty shall be absolute and unconditional irrespective of:

or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Obligations; 
 (f) any
manner of application of collateral, or proceeds thereof, to all or any of the Obligations, or any manner of sale or other disposition of any collateral for all or any of the Obligations or any other assets of the Servicer, any Originator or any of
their Subsidiaries; 
 (g) the existence of any claim, setoff or other rights which any Beneficiary may have at any time
against the Servicer, any Originator or any of their Subsidiaries in connection herewith or any unrelated transaction; 
 (h)
any assignment or transfer of the Obligations or any part thereof permitted under the Purchase and Sale Agreement, this Agreement or any other Transaction Document; 

(i) any change, restructuring or termination of the corporate structure or existence of TXU or any of its Subsidiaries; or 

(j) any other circumstance which might otherwise constitute a defense available to, or a discharge of the Servicer, any
Originator or any of their Subsidiaries or a guarantor. 
 Section 5.3. Waiver. (a) The Performance Guarantor hereby waives
promptness, diligence, notice of acceptance and any other notice with respect to any of the Obligations and this Performance Guaranty and any requirement that any Beneficiary protect, secure, perfect or insure any security interest or lien or any

Final Termination Date, such amount shall be held in trust for the benefit of the Beneficiaries and shall forthwith be paid to the Administrator to be credited and applied to the Obligations, whether matured or unmatured, in accordance with the
terms of the applicable Transaction Document or to be held by the Administrator as collateral security for any Obligations thereafter existing. If the Final Termination Date shall have occurred, the Administrator, on behalf of the itself and the
other Beneficiaries will, at the Performance Guarantor’s request, execute and deliver to the Performance Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation
to the Performance Guarantor of an interest in the Obligations resulting from such payment by the Performance Guarantor. 
 ARTICLE VI

 THE AGENTS 

Section 6.1. Appointment and Authorization. (a) Each Purchaser and Purchaser Agent hereby irrevocably designates and appoints
CACIB, as the “Administrator” hereunder and authorizes the Administrator to take such actions and to exercise such powers as are delegated to the Administrator hereby and to exercise such other powers as are reasonably incidental thereto.
The Administrator shall have no duties or responsibilities except those expressly set forth in this Agreement or in the other Transaction Documents. The duties of the Administrator shall be mechanical and administrative in nature. At no time shall
the Administrator have any duty or responsibility to any Person to investigate or confirm the correctness or accuracy of any information or documents delivered to it in its role as Administrator hereunder or any obligation in respect of the failure
of any Person (other than the Administrator) to perform any obligation hereunder or under any other Transaction Document. The Administrator shall not have, by reason of this Agreement, a fiduciary relationship in respect of any Purchaser Agent,
Purchaser, the Seller, the Servicer or any Originator. Nothing in this Agreement or any of the Transaction Documents, express or implied, is intended to or shall be construed to impose upon the Administrator any obligations in respect of this
Agreement or any of the Transaction Documents except as expressly set forth herein or therein. The Administrator shall not have any duty or responsibility, either initially or on a continuing basis, to provide any Purchaser or any Purchaser Agent
with any credit or other information with respect to the Seller, any Originator, the Servicer, the Performance Guarantor or their Affiliates, whether coming into its possession before the Closing Date or at any time or times thereafter. 

  
 -26- 

 (b) Each Purchaser hereby irrevocably designates and appoints the respective institution
identified as the Purchaser Agent for such Purchaser’s Purchaser Group on the signature pages hereto or in the Assumption Agreement or Transfer Supplement pursuant to which such Purchaser becomes a party hereto, and each authorizes such
Purchaser Agent to take such action on its behalf under the provisions of this Agreement and to exercise such powers and perform such duties as are expressly delegated to such Purchaser Agent by the terms of this Agreement, if any, together with
such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, no Purchaser Agent shall have any duties or responsibilities, except those expressly set forth herein, or any
fiduciary relationship with any Purchaser or other Purchaser Agent or the Administrator, and no implied covenants, functions, responsibilities, duties, obligations or liabilities on the part of such Purchaser Agent shall be read into this Agreement
or otherwise exist against such Purchaser Agent. 
 (c) Except as otherwise specifically provided in this Agreement, the provisions of this
Article VI are solely for the benefit of the Purchaser Agents, the Administrator and the Purchasers, and none of the Seller or Servicer shall have any rights as a third party beneficiary or otherwise under any of the provisions of this
Article VI, except that this Article VI shall not affect any obligations which any Purchaser Agent, the Administrator or any Purchaser may have to the Seller or the Servicer under the other provisions of this Agreement. Furthermore, no
Purchaser shall have any rights as a third-party beneficiary or otherwise under any of the provisions hereof in respect of a Purchaser Agent which is not the Purchaser Agent for such Purchaser. 

(d) In performing its functions and duties hereunder, the Administrator shall act solely as the agent of the Purchasers and the Purchaser
Agents and does not assume nor shall be deemed to have assumed any obligation or relationship of trust or agency with or for the Seller or Servicer or any of their successors and assigns. In performing its functions and duties hereunder, each
Purchaser Agent shall act solely as the agent of its respective Purchaser and does not assume nor shall be deemed to have assumed any obligation or relationship of trust or agency with or for the Seller, the Servicer, any other Purchaser, any other
Purchaser Agent or the Administrator, or any of their respective successors and assigns. 
 Section 6.2. Delegation of Duties.
The Administrator may execute any of its duties through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrator shall not be responsible for the negligence or
misconduct of any agents or attorneys-in-fact selected by it with reasonable care. 
 Section 6.3. Exculpatory Provisions. None
of the Purchaser Agents, the Administrator or any of their respective directors, officers, agents or employees shall be liable for any action taken or omitted (i) with the consent or at the direction of the Majority Purchaser Agents (or in the
case of any Purchaser Agent, the Purchasers within its Purchaser Group that have a majority of the aggregate Commitments of such Purchaser Group) or (ii) in the absence of such Person’s gross negligence or willful misconduct. The
Administrator shall not be responsible to any Purchaser, Purchaser Agent or other Person for (i) any recitals, representations, warranties or other statements made by the Seller, the Servicer, any Originator or any of their Affiliates,
(ii) the value, validity, effectiveness, genuineness, enforceability or sufficiency of any Transaction Document, (iii) any failure of the Seller, the Servicer, any Originator or any of their Affiliates to perform any obligation hereunder
or under the other Transaction Documents to which it is a party (or under any Contract), or (iv) the satisfaction of any condition specified in Exhibit II. The Administrator shall not have 

  
 -27- 

 
any obligation to any Purchaser or Purchaser Agent to ascertain or inquire about the observance or performance of any agreement contained in any Transaction Document or to inspect the properties,
books or records of the Seller, the Servicer, any Originator or any of their respective Affiliates. Section 1.10 provides a mechanism for determining an alternative rate of interest in the event that the London interbank offered rate is
no longer available or in certain other circumstances. 
 Section 6.4. Reliance by Agents. (a) Each Purchaser Agent and the
Administrator shall in all cases be entitled to rely, and shall be fully protected in relying, upon any document or other writing or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person and
upon advice and statements of legal counsel (including counsel to the Seller), independent accountants and other experts selected by the Administrator. Each Purchaser Agent and the Administrator shall in all cases be fully justified in failing or
refusing to take any action under any Transaction Document unless it shall first receive such advice or concurrence of the Majority Purchaser Agents (or in the case of any Purchaser Agent, the Purchasers within its Purchaser Group that have a
majority of the aggregate Commitment of such Purchaser Group), and assurance of its indemnification, as it deems appropriate. 
 (b) The
Administrator shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Majority Purchaser Agents or the Purchaser Agents, and such request and any action taken or failure
to act pursuant thereto shall be binding upon all Purchasers, the Administrator and Purchaser Agents. 
 (c) The Purchasers within each
Purchaser Group with a majority of the Commitments of such Purchaser Group shall be entitled to request or direct the related Purchaser Agent to take action, or refrain from taking action, under this Agreement on behalf of such Purchasers. Such
Purchaser Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of such Majority Purchaser Agents, and such request and any action taken or failure to act pursuant
thereto shall be binding upon all of such Purchaser Agent’s Purchasers. 
 (d) Unless otherwise advised in writing by a Purchaser Agent
or by any Purchaser on whose behalf such Purchaser Agent is purportedly acting, each party to this Agreement may assume that (i) such Purchaser Agent is acting for the benefit of each of the Purchasers in respect of which such Purchaser Agent
is identified as being the “Purchaser Agent” in the definition of “Purchaser Agent” hereto, as well as for the benefit of each assignee or other transferee from any such Person, and (ii) each action taken by such Purchaser
Agent has been duly authorized and approved by all necessary action on the part of the Purchasers on whose behalf it is purportedly acting. Each Purchaser Agent and its Purchaser(s) shall agree amongst themselves as to the circumstances and
procedures for removal, resignation and replacement of such Purchaser Agent. 
 Section 6.5. Notice of Termination Events.
Neither any Purchaser Agent nor the Administrator shall be deemed to have knowledge or notice of the occurrence of any Termination Event or Unmatured Termination Event unless the Administrator and the Purchaser Agents have received notice from any
Purchaser, the Servicer or the Seller stating that a Termination Event or an Unmatured Termination Event has occurred hereunder and describing such Termination Event or Unmatured Termination Event. In the event that the Administrator receives such a
notice, it 

  
 -28- 

 
shall promptly give notice thereof to each Purchaser Agent whereupon each such Purchaser Agent shall promptly give notice thereof to its related Purchasers. In the event that a Purchaser Agent
receives such a notice (other than from the Administrator), it shall promptly give notice thereof to the Administrator. The Administrator shall take such action concerning a Termination Event or an Unmatured Termination Event as may be directed by
the Majority Purchaser Agents (unless such action otherwise requires the consent of all Purchasers), but until the Administrator receives such directions, the Administrator may (but shall not be obligated to) take such action, or refrain from taking
such action, as the Administrator deems advisable and in the best interests of the Purchasers and the Purchaser Agents. 
 Section 6.6.
Non-Reliance on Administrator and Purchaser Agents. Each Purchaser expressly acknowledges that none of the Administrator, the Purchaser Agents nor any of their respective officers, directors, employees, agents, attorneys-in-fact or Affiliates
has made any representations or warranties to it and that no act by the Administrator, or any Purchaser Agent hereafter taken, including any review of the affairs of the Seller, the Performance Guarantor, the Servicer or any Originator, shall be
deemed to constitute any representation or warranty by the Administrator or such Purchaser Agent, as applicable. Each Purchaser represents and warrants to the Administrator and the Purchaser Agents that, independently and without reliance upon the
Administrator, Purchaser Agents or any other Purchaser and based on such documents and information as it has deemed appropriate, it has made and will continue to make its own appraisal of and investigation into the business, operations, property,
prospects, financial and other conditions and creditworthiness of the Seller, the Performance Guarantor, the Servicer or any Originator, and the Receivables and its own decision to enter into this Agreement and to take, or omit, action under any
Transaction Document. Except for items specifically required to be delivered hereunder, the Administrator shall not have any duty or responsibility to provide any Purchaser Agent with any information concerning the Seller, the Performance Guarantor,
the Servicer or any Originator or any of their Affiliates that comes into the possession of the Administrator or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates. 

Section 6.7. Administrator, Purchasers, Purchaser Agents and Affiliates. Each of the Administrator, the Purchasers and the
Purchaser Agents and any of their respective Affiliates may extend credit to, accept deposits from and generally engage in any kind of banking, trust, debt, equity or other business with the Seller, the Performance Guarantor, the Servicer or any
Originator or any of their Affiliates. With respect to the acquisition of the Eligible Receivables pursuant to this Agreement, each of the Purchaser Agents and the Administrator shall have the same rights and powers under this Agreement as any
Purchaser and may exercise the same as though it were not such an agent, and the terms “Purchaser” and “Purchasers” shall include, to the extent applicable, each of the Purchaser Agents and the Administrator in their individual
capacities. 
 Section 6.8. Indemnification. Each Committed Purchaser shall indemnify and hold harmless the Administrator (but
solely in its capacity as Administrator) and its respective officers, directors, employees, representatives and agents (to the extent not reimbursed by the Seller, the Servicer, the Performance Guarantor or any Originator and without limiting the
obligation of the Seller, the Servicer, the Performance Guarantor or any Originator to do so), ratably (based on its Commitment) from and against any and all liabilities, obligations, losses, damages, penalties, judgments, settlements, costs,
expenses and disbursements of any kind whatsoever (including in 

  
 -29- 

 
connection with any investigative or threatened proceeding, whether or not the Administrator or such Person shall be designated a party thereto) that may at any time be imposed on, incurred by or
asserted against the Administrator or such Person as a result of, or related to, any of the transactions contemplated by the Transaction Documents or the execution, delivery or performance of the Transaction Documents or any other document furnished
in connection therewith (but excluding any such liabilities, obligations, losses, damages, penalties, judgments, settlements, costs, expenses or disbursements resulting solely from the gross negligence or willful misconduct of the Administrator or
such Person as determined by final non-appealable judgment of a court of competent jurisdiction). 
 Section 6.9. Successor
Administrator. The Administrator may, upon at least thirty (30) days’ prior written notice to the Seller, each Purchaser and Purchaser Agent, resign as Administrator. Such resignation shall not become effective until (x) a
successor Administrator is appointed by the Majority Purchaser Agents and has accepted such appointment and (y) so long as no Termination Event has occurred and is continuing, the Seller shall have consented to such successor Administrator
(such consent not to be unreasonably withheld or delayed). Upon such acceptance of its appointment as Administrator hereunder by a successor Administrator, such successor Administrator shall succeed to and become vested with all the rights and
duties of the retiring Administrator, and the retiring Administrator shall be discharged from its duties and obligations under the Transaction Documents. After any retiring Administrator’s resignation hereunder, the provisions of Sections
1.5 and 1.7 and Articles III, V and VI shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Administrator. 

ARTICLE VII 

MISCELLANEOUS 

Section 7.1. Amendments, Etc. No amendment or waiver of any provision of this Agreement or any other Transaction Document, or
consent to any departure by the Seller, any Originator, the Performance Guarantor or the Servicer therefrom, shall be effective unless in a writing signed by the Administrator, the Majority Purchaser Agents, and, in the case of an amendment, by the
Seller and the Servicer; provided, however, that no such amendment or waiver shall, (a) without the consent of each affected Purchaser, (i) extend the date of any payment or deposit of Collections by the Seller or the Servicer or
decrease the outstanding amount of or rate of Discount or extend the repayment of or any scheduled payment date for the payment of any Discount in respect of any portion of Capital or any fees owed to a Purchaser; (ii) reduce any fees payable
to any Purchaser Agent or any Purchaser pursuant to the Purchaser Group Fee Letter, (iii) forgive or waive or otherwise excuse any repayment of Capital or change the amount of Capital of any Purchaser; (iv) increase the Commitment of any
Purchaser; (v) amend or modify the provisions of this Section 7.1 or the definition of “Aggregate Capital”, “Capital”, “Change in Control,” “Eligible Receivable”, “Facility Termination
Date”, “Majority Purchaser Agents”, “Net Receivables Pool Balance”, “Purchased Interest”, “Termination Day” or “Total Reserves”; (vi) release all or substantially all of the Pool Assets
from the security interest granted by the Seller to the Administrator hereunder; (vii) terminate the Performance Guaranty and/or release the Performance Guarantor from its obligations thereunder; or (viii) amend or modify any defined term
(or any term used directly or indirectly in such defined term) used in clauses (i) through (vii) above in a manner that would circumvent the intention of the restrictions set forth in such clauses, (b) without the consent of the
Majority Purchaser Agents, amend, waive or modify any provision 

  
 -30- 

 
expressly requiring the consent of the Majority Purchaser Agents and (c) without the consent of the
Administrator, the Majority Purchaser Agents and each Required Initial Purchaser Agent and Purchaser, amend, waive or modify paragraph (i) of Exhibit V
or waive any Termination Event arising from such paragraph
(i)Exhibit V. Each such amendment, waiver or consent shall be effective only in the specific instance
and for the specific purpose for which it was given. No failure on the part of any Purchaser Agent, any Purchaser or the Administrator to exercise, and no delay in exercising any right hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. Notwithstanding the foregoing, it is agreed that any Administrator Fee Letter may be amended, supplemented or
otherwise modified solely with the consent of the parties thereto. 
 Section 7.2. Notices, Etc. All notices, demands and
other communications provided for hereunder shall, unless otherwise stated herein, be in writing (including facsimile and email communications) and shall be personally delivered or sent by facsimile or email, or by overnight mail, to the intended
party at the mailing or email address or facsimile number of such party set forth on Schedule V hereto (or in any other document or agreement pursuant to which it is or became a party hereto), or at such other address or facsimile number as
shall be designated by such party in a written notice to the other parties hereto. All such notices and communications shall be effective when received. 

Section 7.3. Successors and Assigns; Participations; Assignments. 

(a) Participations. Except as otherwise specifically provided herein, any Purchaser may sell to one or more Persons (each a
“Participant”) participating interests in the interests of such Purchaser hereunder; provided, that no Purchaser shall grant any participation under which the Participant shall have rights to approve any amendment to or
waiver of this Agreement or any other Transaction Document. Such Purchaser shall remain solely responsible for performing its obligations hereunder, and the Seller, the Servicer, the Performance Guarantor, each Purchaser Agent and the Administrator
shall continue to deal solely and directly with such Purchaser in connection with such Purchaser’s rights and obligations hereunder. A Purchaser shall not agree with a Participant to restrict such Purchaser’s right to agree to any
amendment hereto, except amendments that require the consent of all Purchasers. Any such Participant shall not have any rights hereunder or under the Transaction Documents. The Seller agrees that each Participant shall be entitled to the benefits of
Sections 1.7 and 3.3 (subject to the requirements and limitations therein and subject to such Participant’s compliance with the requirements of Section 7.6) to the same extent as if it were a Purchaser and acquired its
interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant shall not be entitled to receive any greater payment under Sections 1.7 or 3.3, with respect to any participation, than its
participating Purchaser would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a change in Law that occurs after the Participant acquired the applicable participation. 

Each Purchaser (or its Purchaser Agent on its behalf) that sells a participation shall, acting solely for this purpose as an agent of the
Seller, maintain a register on which it enters the name and address of its Participants and the amounts of each such Participant’s interest in any Capital, Commitments or other rights or obligations hereunder (the “Participant
Register”); provided that 

  
 -31- 

 
no Purchaser or Purchaser Agent shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a
Participant’s interest in such Capital, Commitments or other rights or obligations hereunder) to any Person except to the extent that such disclosure is necessary to establish that such Capital, Commitments or other rights or obligations
hereunder is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Purchaser shall treat each Person whose name is
recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrator (in its capacity as Administrator) shall have no
responsibility for maintaining a Participant Register. 
 (b) Assignments by Committed Purchasers. Any Committed Purchaser may assign
to one or more Persons (each a “Purchasing Committed Purchaser”), reasonably acceptable to the Administrator and the related Purchaser Agent in its sole discretion, any portion of its Commitment pursuant to a supplement hereto,
substantially in the form of Annex F with any changes as have been approved by the parties thereto (each, a “Transfer Supplement”), executed by each such Purchasing Committed Purchaser, such selling Committed Purchaser, such
related Purchaser Agent and the Administrator and with the consent of the Seller (provided, that the consent of the Seller shall not be unreasonably withheld or delayed and that no such consent shall be required if a Termination Event has
occurred and is continuing; provided, further, that no consent of the Seller shall be required if the assignment is made by any Committed Purchaser to the Administrator, to any other Committed Purchaser, to any Affiliate of the Administrator
or any Committed Purchaser, which Affiliate is a bank or similar financial institution or to any Program Support Provider, which Program Support Provider is a bank or similar financial institution). Any such assignment by Committed Purchaser cannot
be for an amount less than $10,000,000. Upon (i) the execution of the Transfer Supplement, (ii) delivery of an executed copy thereof to the Seller, the Servicer, such related Purchaser Agent and the Administrator and (iii) payment by
the Purchasing Committed Purchaser to the selling Committed Purchaser of the agreed purchase price, if any, such selling Committed Purchaser shall be released from its obligations hereunder to the extent of such assignment and such Purchasing
Committed Purchaser shall for all purposes be a Committed Purchaser party hereto and shall have all the rights and obligations of a Committed Purchaser hereunder to the same extent as if it were an original party hereto. The amount of the Commitment
of the selling Committed Purchaser allocable to such Purchasing Committed Purchaser shall be equal to the amount of the Commitment of the selling Committed Purchaser transferred regardless of the purchase price, if any, paid therefor. The Transfer
Supplement shall be an amendment hereof only to the extent necessary to reflect the addition of such Purchasing Committed Purchaser as a “Committed Purchaser” and any resulting adjustment of the selling Committed Purchaser’s
Commitment. 
 (c) Assignments to Liquidity Providers and other Program Support Providers. Any Conduit Purchaser may at any time grant
to one or more of its Liquidity Providers or other Program Support Providers, participating interests in its rights to the Purchased Interest, and interests in its Capital. In the event of any such grant by such Conduit Purchaser of a participating
interest to a Liquidity Provider or other Program Support Provider, such Conduit Purchaser shall remain responsible for the performance of its obligations hereunder. The Seller agrees that each Liquidity Provider and Program Support Provider of any
Conduit Purchaser hereunder shall be entitled to the benefits of Sections 1.5 and 1.7 and Articles III and IV. 

  
 -32- 

 (d) Other Assignments by Conduit Purchasers. Each party hereto agrees and consents
(i) to any Conduit Purchaser’s assignment, participation, grant of security interests in or other transfers of any portion of, or any of its beneficial interest in, the Purchased Interest, and interests in its Capital (or, in each case,
any portion thereof), including without limitation to any collateral agent in connection with its commercial paper program and (ii) to the complete assignment by any Conduit Purchaser of all of its rights and obligations hereunder to any other
Person, including any Affiliate of the Administrator, and upon such assignment such Conduit Purchaser shall be released from all obligations and duties, if any, hereunder; provided, that such Conduit Purchaser may not, without the prior
consent of its Committed Purchasers and the Administrator, make any such transfer of its rights hereunder unless the assignee (x) is a commercial paper conduit that (i) is principally engaged in the purchase of assets similar to the assets
being purchased hereunder, (ii) has as its Purchaser Agent the Purchaser Agent or an Affiliate thereof of the assigning Conduit Purchaser, (iii) issues commercial paper or other notes with credit ratings substantially comparable to the
ratings of the assigning Conduit Purchaser and (iv) has been consented to by the Seller (provided, that (1) the consent of the Seller shall not be unreasonably withheld or delayed, (2) no such consent shall be required if a
Termination Event has occurred and is continuing and (3) no such consent shall be required if such assignee is another commercial paper conduit administered by the same Program Administrator or an Affiliate thereof) or (y) is a Committed
Purchaser, Liquidity Provider or Program Support Provider for such Conduit Purchaser. Any assigning Conduit Purchaser shall deliver to any assignee a Transfer Supplement with any changes as have been approved by the parties thereto, duly executed by
such Conduit Purchaser, assigning any portion of its interest in the Purchased Interest, and interests in its Capital, to its assignee. Such Conduit Purchaser shall promptly (i) notify each of the other parties hereto of such assignment and
(ii) take all further action that the assignee reasonably requests in order to evidence the assignee’s right, title and interest in such interest in the Purchased Interest, and interests in its Capital, and to enable the assignee to
exercise or enforce any rights of such Conduit Purchaser hereunder. Upon the assignment of any portion of its interest in the Purchased Interest, and interests in its Capital, the assignee shall have all of the rights hereunder with respect to such
interest (except that the Discount therefor shall thereafter accrue at the rate, determined with respect to the assigning Conduit Purchaser unless the Seller, the related Purchaser Agent and the assignee shall have agreed upon a different Discount).

 (e) Register. The Administrator, acting as non-fiduciary agent for the Seller (such agency being solely for Tax purposes) and each
Affected Person and its successors and assigns, to the extent such Person has Purchases, Reinvestments, Capital, or Discount owing thereto), shall maintain at an office of the Administrator, a copy of each Assumption Agreement and Transfer
Supplement delivered to and accepted by it hereunder and a register for the names and addresses of the Purchasers, the Commitment of each Purchaser Group and the aggregate outstanding Capital, and Discount owing to each Purchaser or other Affected
Person from time to time (and such other Affected Person) (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Seller, the Servicer, the Purchasers, and such other Affected Persons shall
treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Purchaser hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Seller, any Purchaser Agent and any Purchaser
(and any such other Affected 

  
 -33- 

 
Person) at any reasonable time and from time to time upon reasonable prior notice. Each Purchaser (and each such other Affected Person) that assigns or transfers all or part of its Purchases or
Reinvestments, and interests in its Capital, shall be required to provide the Administrator with notice of such assignment in order for such assignee’s interests in the Purchases and Reinvestments to be reflected in the Register. Each assignor
may, in connection with any permitted assignment, disclose to the applicable assignee (that shall have agreed to be bound by Section 7.5) any information relating to any Originator, the Servicer, the Seller, the Performance Guarantor or
the Pool Receivables furnished to such assignor by or on behalf of such Originator, the Servicer, the Seller, the Performance Guarantor, any Purchaser or the Administrator. 

(f) Successors and Assigns. Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to mean
the successors and assigns of such party; all covenants, promises and agreements by or on behalf of any parties hereto that are contained in this Agreement shall bind and inure to the benefit of the parties hereto and their respective successors and
assigns. Notwithstanding the foregoing, except as contemplated in Section 4.1(d), none of the Seller, the Servicer or the Performance Guarantor may assign its rights or delegate its obligations hereunder or under any other Transaction
Document or any interest herein or under any other Transaction Document, in each case, without the prior written consent of the Administrator and each Purchaser Agent. 

(g) Enforcement By Agents. Without limiting any other rights that may be available under applicable Law, the rights of the
Administrator, each Purchaser Agent and each Purchaser may be enforced through it or by its agents. 
 (h) Certain Pledges. Without
limiting the right of any Purchaser to sell or grant interests, security interests or participations to any Person as otherwise described in this Section 7.3, any Purchaser may at any time pledge or assign a security interest in all or
any portion of its rights under this Agreement, any portion of its interest in the Purchases or Reinvestments, and interests in its Capital to secure its obligations as a Purchaser hereunder, including any pledge or assignment to secure obligations
to a Federal Reserve Bank, the United States Treasury, the Federal Deposit Insurance Corporation or a security trustee in connection with the funding by such Purchaser of Purchases without notice to or consent of the Seller, the Performance
Guarantor or any other Person; provided that no such pledge or grant of a security interest shall release such Purchaser from any of its obligations hereunder or substitute any such pledgee or grantee for such Purchaser as a party hereto. 

Section 7.4. Costs; Expenses. In addition to the rights of indemnification granted under Section 3.1, the Seller
agrees to pay to the Administrator, the Purchaser Agents and the Purchasers, within 10 Business Days of demand (which demand shall be accompanied by documentation thereof in reasonable detail), all reasonable and documented costs and expenses in
connection with (i) the preparation, execution, delivery and administration of this Agreement (including periodic audits and agreed upon procedures with respect to the Pool Receivables by (or on behalf of) the Administrator), the other
Transaction Documents and the other documents and agreements to be delivered hereunder (and all reasonable and documented costs and expenses in connection with any amendment, waiver or modification of any thereof), including Attorney Costs for the
Administrator, Purchaser Agents, the Purchasers and their respective Affiliates with respect thereto and with respect to advising the Administrator, the Purchaser Agents, the Purchasers and their 

  
 -34- 

 
respective agents, Affiliates as to their rights and remedies under this Agreement and the other Transaction Documents; and (ii) all reasonable and documented costs and expenses (including
Attorney Costs), if any, of the Administrator, the Purchaser Agents, the Purchasers and their respective agents, Affiliates in connection with the enforcement of this Agreement and the other Transaction Documents. 

Section 7.5. Confidentiality. Each of the Seller, the Servicer and the Performance Guarantor agrees (i) not to post to a
website or publish or otherwise distribute to any other Person this Agreement and the other Transaction Documents and (ii) to maintain the confidentiality of the information in this Agreement and the other Transaction Documents relating to

 (b) Without
limiting the generality of the foregoing: 
 (i) Each Purchaser (and each Affected Person, other than the Purchasers, that

thereafter upon the request of the Seller or the Administrator, but only if such Foreign Purchaser is legally entitled to do so), or in the case of a Foreign Affected Party, on or prior to receipt of its first payment under any Transaction Document,
whichever of the following is applicable: 
 (A) in the case of a Foreign Purchaser (or Foreign Affected Party), claiming
eligibility for benefits of an income Tax treaty to which the United States is a party, executed originals of IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable,

behalf of any direct or indirect partner, or 
 (E) duly completed executed originals of any other form prescribed by
applicable Laws as a basis for claiming exemption from or a reduction in United States federal withholding Tax together with such supplementary documentation as may be prescribed by applicable Laws to permit the Seller, the Performance Guarantor or

Seller’s identity as a separate legal entity and to make it apparent to third Persons that the Seller is an entity with assets and liabilities distinct from those of Vistra, the Servicer, each Originator, and any other Person, and is not a
division of Vistra, the Servicer, the Originators, its or their respective other Affiliates or any other Person. Without limiting the generality of the foregoing and in addition to and consistent with the other covenants set forth herein, each of
the Seller and the Servicer shall take such actions as shall be required in order to ensure each of the following until the Final Termination Date: 

  
 Exhibit IV-14 

 (a) The Seller will be a limited liability company whose primary activities are restricted
in its limited liability company agreement to (i) purchasing or otherwise acquiring from any Originator, owning, holding, granting security interests or selling interests in Pool Assets; (ii) entering into agreements for the selling and
servicing of the Receivables Pool; and (iii) conducting such other activities as it deems necessary or appropriate to carry out its primary activities. 

(b) The Seller shall not engage in any business or activity, or incur any indebtedness or liability, other than as expressly permitted by the
Transaction Documents. 
 (c) Not less than one independent manager (the “Independent Manager”) shall be an individual who
(i) is not, and has not at any time during the five-year period prior to his or her appointment as Independent Manager been, a direct, indirect or beneficial owner, officer, director, employee, affiliate, associate or supplier of Vistra, the
Servicer or any of its or their Affiliates (other than his or her service as an independent manager or in a similar capacity of any such Person); and (ii) has at least three years of employment experience with one or more entities that provide,
in the ordinary course of its businesses, advisory, management or placement services to issuers of securitization or structured finance instruments, agreements or securities. The limited liability company agreement of the Seller shall at all times
provide that (i) the Seller’s Manager (as defined in its limited liability company agreement) shall not approve, or take any other action to cause the filing of, a voluntary bankruptcy petition with respect to the Seller unless the Manager
and the Independent Manager shall approve the taking of such action in writing before the taking of such action; and (ii) such provision cannot be amended without the prior written consent of the Independent Manager. 

(d) The Independent Manager shall not at any time serve as a trustee in bankruptcy for the Seller, Vistra, the Servicer or any Originator or
any of their respective other Affiliates. 
 (e) Any employee, consultant or agent of the Seller will be compensated from the Seller’s
funds for services provided to the Seller. The Seller will not engage any agents other than its attorneys, auditors, other professionals, a servicer and any other agent contemplated by the Transaction Documents for the Receivables Pool. 

(f) The Seller will contract with the Servicer, to perform for the Seller all operations required on a daily basis to service the Receivables
Pool. The Seller will pay the Servicer the Servicing Fee pursuant to the Transaction Documents. Except as otherwise permitted by this Agreement, the Seller will not incur any material indirect or overhead expenses for items shared with Vistra or the
Servicer (or any other Affiliate thereof) that are not reflected in the Servicing Fee. To the extent, if any, that the Seller (or any Affiliate thereof) shares items of expenses not reflected in the Servicing Fee or the manager’s fee, such as
legal, auditing and other professional services, such expenses will be allocated to the extent practical on the basis of actual use or the value of services rendered, and otherwise on a basis reasonably related to the actual use or the value of
services rendered; provided, that the Servicer may pay all (or any portion of) the expenses relating to the preparation, negotiation, execution and delivery of the Transaction Documents, including legal, agency and other fees. 

(g) The Seller’s operating expenses will not be paid by Vistra, the Servicer, any Originator or any other Affiliate thereof. 

 

  
 Exhibit IV-15 

 (h) The Seller’s books and records will be maintained separately from those of Vistra,
the Servicer or any Originator or any of their respective other Affiliates. 
 (i) The Seller’s assets shall not be included in the
consolidated financial statements of Vistra, the Servicer or any Originator or any of their respective other Affiliates unless required in accordance with GAAP and any such consolidated financial statements shall contain detailed notes clearly
stating that (i) such Affiliates are separate legal entities and the Seller’s assets and credit are not available to satisfy the debts and obligations of such Affiliates or any other Person and (ii) the Seller’s assets shall be
listed on the Seller’s own separate balance sheet. 
 (j) The Seller’s assets will be maintained in a manner that facilitates their
identification and segregation from those of Vistra, the Servicer or any Originator or any of their respective other Affiliates. 
 (k) The
Seller will strictly observe corporate formalities in its dealings with Vistra, the Servicer or any Originator or any of their respective other Affiliates, and ensure that funds or other assets of the Seller are not commingled with those of Vistra,
the Servicer or any Originator or any of their respective other Affiliates except as permitted by this Agreement. The Seller shall not maintain joint bank accounts or other depository accounts to which Vistra, the Servicer or any Originator or any
of their respective other Affiliates has independent access. 
 (l) The Seller will maintain arm’s-length relationships with each of
Vistra, the Servicer or any Originator (and any of their other Affiliates). Any Person that renders or otherwise furnishes services to the Seller will be compensated by the Seller at market rates for such services it renders or otherwise furnishes
to the Seller. Neither the Seller, on the one hand, nor the Servicer or any Originator, on the other, will be or will hold itself out to be responsible for the debts of the other or the decisions or actions respecting the daily business and affairs
of the other. The Seller and the Servicer will immediately correct any known misunderstanding with respect to the foregoing, and they will not operate or purport to operate as an integrated economic unit with respect to each other or in their
dealing with any other entity. 
 (m) None of Vistra, the Servicer or other Originator shall pay the salaries of Seller’s employees, if
any. 
 (n) No Affiliate of the Seller shall advance funds to, or guaranty debts of, the Seller, except as otherwise provided herein or in
the other Transaction Documents; provided, that an Affiliate of the Seller may provide funds to the Seller in connection with its capitalization. 

(o) The Seller shall not guarantee, and shall not otherwise be liable, with respect to any obligation of any of its Affiliates. 

(p) The Seller shall be, at all times, adequately capitalized to engage in the transactions contemplated in its limited liability company
agreement. 
 (q) Each of the Seller and the Servicer will take such other actions as are necessary on its part to ensure that the facts and
assumptions set forth in the opinion issued by Sidley Austin LLP, as counsel for the Seller, in connection with this Agreement relating to substantive consolidation issues, and in the certificates accompanying such opinion, remain true and correct
in all material respects at all times. 

  
 Exhibit IV-16 

 (s) Notice of Change in Beneficial Ownership. The Performance Guarantor will promptly
notify the Administrator and each Purchaser Agent of any change in the information provided in the Beneficial Ownership Certification for any of the Seller, the Servicer, the Performance Guarantor or any Originator that would result in a change to
the list of beneficial owners identified therein. 

  
 Exhibit IV-17

having been effectively withdrawn or such lien having been released or discharged, or (ii) a notice of any other lien the existence of which could reasonably be expected to have a Material Adverse Effect or a Vistra Group Material Adverse
Effect and ten days shall have elapsed without such notice having been effectively withdrawn or such lien having been released or discharged;

 (n) Margin Reporting; Payments. On or before any day during any Transaction Period

recalculate the Outstanding Amount of the Purchased Note as of such day (after giving effect to such prepayment); (ii) based on such recalculation, shall notify Buyer in writing promptly (but in any event prior to any Seller Party’s receipt of
such prepayment) if such prepayment is expected to decrease the Outstanding Amount of the Purchased Note to an extent sufficient to result in a Margin Deficit exceeding the applicable threshold specified in Paragraph 4(e) of Annex I to the Master
Repurchase Agreement; and (iii) if such be the case, shall make the corresponding Margin Payment to Buyer on such date concurrently with (or immediately following) any Seller Party’s receipt of such prepayment in accordance with Paragraph

deduction required to be made. The Seller agrees to notify the Buyer of any circumstance known or reasonably known to it that causes a certificate or document provided by it pursuant to this subparagraph to fail to be true. 

 

	6.	 Agent. 

6.1 Appointment and Authorization. Each Seller Party hereby irrevocably designates and appoints Seller Party Agent as the agent
of such Seller Party under this Framework Agreement and each of the other Transaction Agreements, and each Seller Party irrevocably authorizes Seller Party Agent, in such capacity, to take such action on its behalf under the provisions of this
Framework Agreement and the other Transaction Agreements and to exercise such powers and perform such duties as are expressly delegated to Seller Party Agent by the terms of this Framework Agreement and the other Transaction Agreements (including
the power to execute and deliver Confirmations on behalf of the Seller in accordance with Article IV of this Framework Agreement and the Master Repurchase Agreement), together with such other powers as are reasonably incidental thereto to the extent
permitted by applicable Law. Each Seller Party hereby further authorizes Seller Party Agent to consent to amendments to this Framework Agreement. Without limiting the generality of the foregoing, Seller Party Agent shall be responsible for
maintaining and the delivering Transaction Notices, Information Packages, Purchase Reports, and for the receipt and distribution of Funded Purchase Price to the Seller. Seller Party Agent hereby agrees that it will promptly deliver to the Seller
copies of each Confirmation and any notices or written information received by Seller Party Agent from Buyer in connection with any Transaction Agreement. Notwithstanding any provision to the contrary elsewhere in this Framework Agreement, Seller
Party Agent shall not have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Seller Party, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into this Framework Agreement or otherwise exist against the Seller Party Agent. 
 6.2
Non-Reliance on Seller Agent and Other Sellers. Each Seller Party expressly acknowledges that neither Seller Party Agent nor any of its respective officers, directors, employees, agents, attorneys-in-fact or Affiliates have made any representations or warranties to it and that no act by the Seller Party Agent hereafter taken, including any review of the
affairs of a party or any affiliate of a party, shall be deemed to constitute any representation or warranty by Seller Party Agent to any Seller Party. Each Seller Party represents to Seller Party Agent that it has, independently and without
reliance upon Seller Party Agent or any other Seller Party, and based on such documents and information as it has deemed appropriate, made its own appraisal of, and investigation into, the business, operations, property, financial and other
condition and creditworthiness of Buyer and its Affiliates and made its own decision to enter into this Framework Agreement and the other Transaction Agreements, including any Transactions hereunder. Each Seller Party also represents that it will,
independently and without reliance upon Seller Party Agent or any other Seller Party, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis, appraisals and decisions in taking or not
taking action under this Framework Agreement, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition 

  
 17 

 
and creditworthiness of Buyer and its Affiliates. Except for notices, reports and other documents expressly required to be furnished to the Seller Parties by Seller Party Agent hereunder, Seller
Party Agent shall not have any duty or responsibility to provide any Seller Party with any other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of Buyer or any Affiliate
of Buyer which may come into the possession of the Seller Party Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates. 

6.3 Indemnification. The Seller Parties agree to, jointly and severally, indemnify Seller Party Agent in its capacity as such from and
against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever (collectively, “Losses”) which may at any time (including at any time following
the payment of any Funded Purchase Prices) be imposed on, incurred by or asserted against Seller Party Agent in any way relating to or arising out of this Framework Agreement, or any documents contemplated by or referred to herein or therein or the
transactions contemplated hereby or thereby or any action taken or omitted by the Seller Party Agent under or in connection with any of the foregoing; provided that no Seller Party shall be liable for the payment of any portion of such
Losses which are found by a final and nonappealable decision of a court of competent jurisdiction to the extent that such Losses have resulted from Seller Party Agent’s gross negligence or willful misconduct. The agreements in this
Section 6.3 shall survive the payment of all Funded Purchase Prices and Funded Repurchase Prices and all other amounts payable hereunder. Notwithstanding anything to the contrary herein, without limiting the rights of indemnification above with
respect to Losses as settled by third parties, the Parties agree not to assert any claim for special, indirect, consequential or punitive damages against the other Party hereto, any of their affiliates or any of their respective directors, officers,
employees, attorneys and agents or any other indemnified person on any theory of liability arising from this Master Framework, the use of proceeds thereof or any claim, litigation, investigation or proceeding relating to any of the foregoing. 

6.4 Agent in Its Individual Capacity. Seller Party Agent and its Affiliates may make sales to, make purchases from and generally engage
in any kind of business with any Seller Party, Buyer or Guarantor as though Seller Party Agent were not an agent. With respect to any Transactions to which it is a party and any sales or repurchases of the Seller Note made or renewed by it, Seller
Party Agent shall have the same rights and powers under this Framework Agreement as the Seller and may exercise the same as though it were not an agent, and the term “Seller” shall include the Seller Party Agent in its individual capacity.

  

	7.	 Payment to the Seller Party Agent; Certain Calculations; Originators. 

7.1 Payments to the Seller Party Agent. Notwithstanding anything to the contrary contained herein, all amounts payable in cash by
Buyer to the Seller in connection with any Transaction (including all payments of Funded Purchase Price on any applicable Purchase Dates) shall be paid to the Seller Party Agent, and the Seller Party Agent shall distribute such payments to the
Seller (and in the case of payments on account of the Seller Note for further payment to the applicable Originator) in accordance with the respective amounts of Purchase Price (or any other amounts) owing to the Seller in connection with each
applicable Transaction (after giving effect to applicable netting pursuant to Paragraph 12 of each Master Repurchase Agreement). As 

  
 18 

 
between Buyer and the Seller, any payment of such amounts to the Seller Party Agent shall be treated as payments to the Seller and shall discharge Buyer’s obligations with respect to such
payments regardless of whether the Seller Party Agent distributes such payments to the Seller, and Buyer shall have no liability for the failure of the Seller Party Agent to comply with the preceding sentence. 

7.2 Certain Calculations. Buyer shall calculate the Funded Purchase Prices, Funded Repurchase Prices, the Outstanding Buyer Balance, the
amounts of any fees payable under the Fee Letter and all other amounts to be calculated under the Transaction Agreements (except as set forth below), as well as any adjustments thereto, which calculations shall be conclusive absent manifest error.
Upon the reasonable request of the Seller Party Agent for any such calculations, Buyer shall promptly provide such calculations to such Person. 

7.3 Security Interest. 

(a) Each Originator hereby grants to Buyer a first priority security interest in all of such Originator’s right, title, benefit and
interest in the Purchased Note sold in each Transaction entered into under the Master Repurchase Agreement and all proceeds thereof (collectively, the “Originator Collateral”) to secure the Seller’s obligations under the Transaction
Agreements (the “Secured Obligations”). This Framework Agreement shall create a continuing security interest in the Originator Collateral and shall remain in full force and effect (notwithstanding any repurchase by the Seller of the
Purchased Note under an expiring Transaction and simultaneous purchase by Buyer of the Purchased Note under a subsequent Transaction) until all unpaid Repurchase Price with respect to outstanding Transactions under the Master Repurchase Agreement
have been indefeasibly paid in full. Buyer shall have, with respect to all the Originator Collateral, in addition to all other rights and remedies available to Buyer under the Transaction Agreements, all the rights and remedies of a secured party
under the Uniform Commercial Code as in effect in any applicable jurisdiction. 
 (b) Each Originator hereby authorizes Buyer to file such
financing statements (and continuation statements with respect to such financing statements when applicable) as may be necessary to perfect the security interest granted pursuant to the foregoing Section 7.3(a) under the Uniform Commercial Code
of the relevant jurisdiction. 
 7.4 Sale and Assignment. Each Originator hereby consents to the occurrence of each Transaction with
respect to the Seller Note entered into by the Seller Party Agent pursuant to the terms of the Transaction Agreements, including the transfer by the Seller of the Seller Note to the Buyer. Concurrently with the occurrence of each Transaction with
respect to the Seller Note pursuant to the Transaction Agreements, each Originator shall be deemed to have sold and assigned all of its rights (subject to Permitted Liens) in the Seller Note to Buyer, in each case, to the same extent as such sale
and assignment by the Seller to Buyer of the Seller Note. 
 7.5 Tax Matters. All payments made by or on account of any obligation of
any Seller Party under any Transaction Agreement shall be made free and clear of, and without deduction or withholding for or on account of any Taxes, except as required by applicable Law. If any applicable Law (as determined in the good faith
discretion of such Seller Party) requires the deduction or withholding of any Tax from any such payment by such Seller Party, then such Seller Party shall 

  
 19 

 
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, such
Seller Party, except to the extent of such Tax that is an Excluded Tax, shall increase its sum payable as necessary so that after such deduction or withholding has been made (including any deduction or withholding of Taxes imposed upon additional
payments made pursuant to this Section 7.5 of this Framework Agreement), the Buyer receives an amount equal to the sum it would have received had no such deduction or withholding been made. 

8. Indemnification. 
 8.1
Seller Parties’ Indemnity. 
 (a) General Indemnity. Without limiting any other rights which any such Person may have
hereunder or under applicable Law, each Seller Party, jointly and severally, hereby agrees to indemnify and hold harmless Buyer, Buyer’s Affiliates and all of their respective successors, transferees, participants and assigns, and all officers,
members, managers, directors, shareholders, employees and agents of any of the foregoing (each an “Indemnified Person”), from and against any and all damages, losses, claims, liabilities and related documented out-of-pocket costs and expenses, including reasonable external attorneys’ fees and disbursements and all costs and expenses incurred, including reasonable external
attorneys’ fees and disbursements, in connection with the enforcement of this provision (all of the foregoing being collectively referred to as “Indemnified Amounts”) arising out of or resulting from this Framework Agreement or any
other Transaction Agreement, any of the transactions contemplated thereby, or the ownership, maintenance or purchasing of the Purchased Note, or any actions or inactions of any Vistra Party. Without limiting or being limited by the foregoing, each
Seller Party, jointly and severally, shall pay on demand to each Indemnified Person any and all amounts necessary to indemnify the Indemnified Person from and against any and all Indemnified Amounts relating to or resulting from any of the
following: 
 (i) the transfer by such Seller Party of any interest in the Purchased Note or any proceeds thereof, other than
in connection with Transactions entered into with Buyer pursuant to the Transaction Agreements; 
 (ii) any representation,
warranty or statement made or deemed made by such Seller Party (or any of its officers) under or in connection with this Framework Agreement, any of the other Transaction Agreement, any Information Package, Purchase Report or any other information
or report delivered by or on behalf of such Seller Party pursuant hereto, which shall have been untrue, false or incorrect when made or deemed made; 

(iii) the failure of such Seller Party, the Seller Party Agent or the Securitization Servicer to comply with the terms of any
Transaction Agreement, the Seller Note, any Securitization Documents or any applicable Law, or the nonconformity of the Seller Note with any such applicable Law; 

(iv) the lack of an enforceable ownership interest or a first priority perfected security interest in the Purchased Note
transferred by such Seller Party, or purported to be transferred by such Seller Party, to Buyer pursuant to the Transaction Agreements against all Persons (including any bankruptcy trustee or similar Person); 

  
 20 

 (v) any attempt by any Person to void the transfers by such Seller Party
contemplated hereby under statutory provisions or common law or equitable action; 
 (vi) the failure to have filed, or any
delay in filing, financing statements, financing statement amendments, continuation statements or other similar instruments or documents under the UCC of any applicable jurisdiction or other applicable Laws with respect to the Purchased Note
transferred by such Seller Party, or purported to be transferred by such Seller Party, to Buyer pursuant to the Transaction Agreements, whether as of the applicable Purchase Date or at any subsequent time; 

(vii) any dispute, claim, offset, defense (other than discharge in bankruptcy), or other similar claim or defense of the
Receivables Entity to the payment when due of the Purchased Note transferred, or purported to be transferred, by such Seller Party to Buyer pursuant to the Transaction Agreements (including a defense based on the Purchased Note not being a legal,
valid and binding obligation of the Receivables Entity enforceable against it in accordance with its terms); 
 (viii) any
failure of such Seller Party or the Securitization Servicer to perform any of its duties or obligations arising under or in connection with the Purchased Note in accordance with the provisions thereof or of any of the other Securitization Facility
Documents; 
 (ix) any suit or claim related to the Purchased Note transferred by such Seller Party, or purported to be
transferred by such Seller Party, to Buyer pursuant to the Transaction Agreements; 
 (x) any investigation, litigation or
proceeding (actual or threatened) related to this Framework Agreement or any other Transaction Agreement or the use of proceeds of any purchase hereunder or in respect of the Purchased Note; 

(xi) any failure of such Seller Party or Seller Party Agent to comply with its covenants, obligations and agreements contained
in this Framework Agreement or any other Transaction Agreement; 
 (xii) any civil penalty or fine assessed by OFAC or any
other Governmental Authority administering any anti-corruption law or Sanctions, and all reasonable costs and expenses (including reasonable documented legal fees and disbursements) incurred in connection with defense thereof by, any Indemnified
Person in connection with the Transaction Agreements as a result of any action of any Seller Party or any of its respective Affiliates; 

(xiii) any Taxes (other than Excluded Taxes) imposed upon any Indemnified Person or upon or with respect to the Purchased Note
transferred by such Seller Party, or purported to be transferred by such Seller Party, to Buyer pursuant to the Transaction Agreements arising by reason of the purchase or ownership of the Purchased Note (or of any interest therein); 

  
 21 

 (xiv) any inability of such Seller Party to transfer the Purchased Note as
contemplated under the Transaction Agreements; or 
 (xv) the violation or breach by such Seller Party or Seller Party Agent
of any confidentiality provision, or of any similar covenant of non-disclosure, with respect to the Purchased Note; 

provided, however, that no Seller Party shall be required to indemnify any Indemnified Person to the extent of any amounts are determined by a
court of competent jurisdiction by final and nonappealable judgment to have resulted from the fraud, gross negligence or willful misconduct of such Indemnified Person. 

8.2 Contribution. If for any reason the indemnification provided above in this Article 8 is unavailable to an Indemnified Person or is
insufficient to hold an Indemnified Person harmless, then each Seller Party shall contribute to the amount paid or payable by such Indemnified Person as a result of such loss, claim, damage or liability in such proportion as is appropriate to
reflect not only the relative benefits received by such Indemnified Person on the one hand and such Seller Party on the other hand but also the relative fault of such Indemnified Person as well as any other relevant equitable considerations. 

 

	9.	 Miscellaneous. 

Except as otherwise expressly set forth in a Transaction Agreement, the following will apply to all Transaction Agreements: 

9.1 Further Assurances. Each Seller Party and the Seller Party Agent agrees that from time to time it will promptly execute and deliver

9.17 Tax Treatment. Buyer and each Seller Party will treat the Transactions effected by the Transaction Agreements for U.S. federal and
state tax purposes as loans by Buyer secured by the applicable Collateral (“Intended Tax Treatment”). Buyer and Seller Parties, as applicable, each agree to prepare its U.S. federal and state Tax returns, if required, in a manner
