(a) each Receivable generated by such Originator prior to the Purchase and Sale Termination Date, whether now existing or

 (c) all monies due or to become due to such Originator with respect to any
of the foregoing; 
 all books and records of such Originator to the extent related to any of the foregoing, together with
all rights (but not obligations) of such Originator under the Contracts with respect to such Receivables to which such Originator is a party; and 

(e) all Collections and other proceeds (as defined in the UCC) of any of the foregoing (including, without limitation, invoice
price, finance charges, interest and all other charges) received by (or for the account of) such Originator in respect of any of the foregoing (including, without limitation, net proceeds of sale or other disposition of repossessed goods or other

All purchases, contributions and assignments hereunder shall be made without recourse, but shall be made pursuant to, and in reliance upon,
the representations, warranties and covenants of such Originator set forth in this Agreement and each other Transaction Document to which such Originator is a party. No obligation or liability to any Obligor on any Receivable is intended to be
assumed by the Company hereunder, and any such assumption is expressly disclaimed. The Company’s foregoing commitment to purchase Receivables and the proceeds and rights described in clauses (b) through

Section 1.2 Timing of Purchases and Contributions. 

(a) Closing Date Purchases and Contributions. Each Originator’s entire right, title and interest in (i) each Receivable that existed
and was owing to such Originator on the Closing Date for such Originator and (ii) all Related Rights with respect thereto automatically shall be deemed to have been sold or contributed, as applicable, by such Originator to the Company on the

 (b) Subsequent Purchases and Contributions. After the Closing Date for any Originator, on each Business Day until the

the conditions set forth in this Agreement, the Company agrees to pay the applicable Purchase Price to the applicable Originator in accordance with Article III and to reflect all capital contributions in accordance with

 Section 1.5 Intention of the Parties. It is the express intent of each
Originator and the Company that each conveyance by such Originator to the Company pursuant to this Agreement of any Receivables and Related Rights, including, without limitation, all Sold Receivables, if any, constituting “accounts,”
“chattel paper,” “payment intangibles,” “instruments” or “general intangibles” (each as defined in the UCC), be construed as a valid and perfected sale or contribution, as the case may be, and absolute
assignment (without recourse except as provided herein) of such Receivables and Related Rights by such Originator to the Company (rather than the grant of a security interest to secure a debt or other obligation of such Originator) and that the
right, title and interest in and to such Receivables and Related Rights conveyed to the Company be prior to the rights of and enforceable against all other Persons at any time, including, without limitation, lien creditors, secured lenders,
purchasers and any Person claiming through such Originator. The parties acknowledge that an outright sale of receivables and interests in receivables is governed by Article 9 of the UCC (“Article 9”), notwithstanding that such a
sale is not intended for security. The parties also acknowledge that, as a drafting convention under Article 9, terms used under Article 9 for secured transactions also apply to outright sales of receivables, including “debtor,” which
applies to a seller of receivables, “secured party,” which applies to a buyer of receivables, and “security interest,” which applies to the buyer’s outright ownership interest. Thus, such terms, and other terms used in
Article 9, will apply to this Agreement, and may be used in this Agreement or in connection with this Agreement and such use does not affect the nature of the outright sale or contribution hereunder of the Receivables by the Originators to the
Company. Thus, under the Article 9 drafting convention, the outright sale or contribution of the Sold Receivables may be described as a transaction by which the Originators have granted to the Company a security interest in, among other things, the
Sold Receivables. However, if, contrary to the mutual intent of the parties, any conveyance hereunder of Receivables and Related Rights is not construed to be both a valid and perfected sale and absolute assignment of such Receivables and Related
Rights, and a conveyance of such Receivables and Related Rights that is prior to the rights of and enforceable against all other Persons at any time, including, without limitation, lien creditors, secured lenders, purchasers and any Person claiming
through any Originator, then, it is the intent of such Originator and the Company that (i) this Agreement also shall be deemed to be, and hereby is, a security agreement within the meaning of the UCC; and (ii) such Originator shall be
deemed to have granted to the Company as of the date of this Agreement, and such Originator hereby grants to the Company, a security interest in, to and under, all of such Originator’s right, title and interest in and to each Receivable
generated by such Originator prior to the Purchase and Sale Termination Date and all Related Rights with respect thereto, whether now existing or hereafter created by such Originator to secure the prompt and complete payment of a loan deemed to have
been made in an amount equal to the Purchase Price of the Receivables originated by such Originator, together with all other obligations of such Originator hereunder. 

ARTICLE II 
 CALCULATION
OF PURCHASE PRICE 
 Section 2.1 Calculation of Purchase Price. The “Purchase Price” to be paid to each
Originator for the Receivables that are purchased hereunder from such Originator shall be (i) determined in accordance with the following formula and (ii) subject to the reductions as provided in Sections 3.3(i): 

  
 6 

 
  














					
	PP	  	=	  	OB x [1 - FMVD]
			
	where:	  		  	
			
	PP	  	=	  	Purchase Price for each Receivable as calculated on the relevant Payment Date.
			
	OB	  	=	  	The Outstanding Balance of such Receivable on the relevant Payment Date.
			
	FMVD	  	=	  	2.07% or such other percentage as agreed to between such Originator and the Company to reflect a fair market price for the Receivables.

an amount to be agreed between the Company and such Originator) and partially by the delivery of proceeds of a subordinated loan made by such Originator to the Company in an initial principal amount equal to the remaining Purchase Price, which loan
shall be evidenced by a promissory note in the form of Exhibit A (each such promissory note issued to an Originator, as it may be amended, supplemented, endorsed or otherwise modified from time to time, together with all promissory notes
issued from time to time in substitution therefor or renewal thereof in accordance with the Transaction Documents, being herein called a “Company Note”), or (b) with respect to Receivables originated by TXU, accept a

 (a) FIRST, in cash to the extent the Company has cash available therefor and such payment is not prohibited under the
Receivables Purchase Agreement; and 
 (b) SECOND, to the extent any portion of the Purchase Price remains unpaid, the
principal amount outstanding under such Originator’s Company Note shall be automatically increased by an amount equal to such remaining Purchase Price, so long as the aggregate principal amount of all of the Company Notes does not cause the
Company’s tangible net worth to be less than the greater of (i) $8,400,000 and (ii) the amount that is 2.4% of the Purchase Limit as of such date.

 The total consideration paid by the Company to each Originator for each sale of Receivables
by such Originator hereunder shall represent a reasonable arm’s length price for the Receivables so sold by such Originator and shall constitute reasonably equivalent value for the Receivables so sold by such Originator. 

Each Originator shall make all appropriate record keeping entries with respect to the Company Notes payable to it to reflect the foregoing
payments and reductions made pursuant to Section 3.3, and such Originator’s books and records shall constitute rebuttable presumptive evidence of the principal amount of, and accrued interest on, the Company Note payable to
such Originator at any time. 
 (b) As contemplated in Sections 1.1 and 1.2, TXU may (but shall have no obligation to), from time to time
subsequent to the Closing Date for TXU, contribute Receivables to the capital of the Company. All such contributions shall be properly reflected by TXU and the Company in their respective books and records. 

Section 3.3 Settlement as to Specific Receivables and Deemed Collections. If on any day there are unpaid Deemed Collections with
respect to Sold Receivables, then such Deemed Collections shall be paid as follows: 
 (i) as long as no Termination Event exists under the
Receivables Purchase Agreement and the Purchase and Sale Termination Date has not occurred, the amount of such Deemed Collections shall be paid, first, by means of a reduction of the Purchase Price payable by the Company to the applicable Originator
on such day; second, if the amount of such Deemed Collections exceeds the Purchase Price payable to the applicable Originator, the remaining amount of Deemed Collections shall be paid by means of a reduction of the principal amount outstanding under
the Company Note payable to such Originator (to the extent of any outstanding principal amount under the Company Note payable to such Originator); and, third, any remaining amount of Deemed Collections shall be paid by the applicable Originator to
the Company, on the first Settlement Date after the event giving rise the applicable Deemed Collection, by deposit in immediately available funds of such remaining amount into a Collection Account or the Concentration Account; or 

(ii) if a Termination Event exists under the Receivables Purchase Agreement or the Purchase and Sale Termination Date has occurred, all Deemed
Collections shall be paid by the applicable Originator to the Company on the first Settlement Date after the event giving rise to the applicable Deemed Collection by deposit in immediately available funds of the amount of such Deemed Collections
into a Collection Account or the Concentration Account. 
 Section 3.4 Reconveyance of Receivables. In the event that an
Originator has paid to the Company the full Outstanding Balance of any Sold Receivable pursuant to Section 3.3, such Originator may elect to have the Company reconvey such Sold Receivable to such Originator. Any such reconveyance shall be
without recourse and without representation or warranty except that such Sold Receivable is free and clear of all liens, security interests, charges, and encumbrances created by the Company. Once so reconveyed by the Company to such Originator, such
Originator shall not thereafter sell or contribute such Receivable to the Company.

writing or other right of any kind held or transmitted by such Originator or transmitted or received by the Company (whether or not from such Originator) in connection with any Receivable or Related Rights sold, contributed or otherwise conveyed or
purported to be conveyed by it hereunder. Each Originator hereby acknowledges and consents to the powers of attorney granted by the Company and the Servicer to the Administrator pursuant to Section 4.4(b) of the Receivables
Purchase Agreement. 
 Section 7.3 Further Action Evidencing Purchases. Each Originator agrees that from time to time, at its
expense, it will promptly execute and deliver all further instruments and documents, and take all further action that the Company, the Servicer or the Administrator (as the Company’s assignee) may reasonably request in order to perfect, protect
or more fully evidence the Sold Receivables and Related Rights purchased by or contributed to the Company hereunder, or to enable the Company or the Administrator (as the Company’s assignee) to exercise or enforce any of its rights hereunder.

or its designee or assignee (including, without limitation, the Servicer and the Administrator) incurred in connection therewith shall be payable by such Originator.

shall, except as otherwise specified by such Obligor or required by applicable law and unless otherwise instructed by the Servicer (with the prior written consent of the Administrator) or the Administrator, be applied as a Collection of any
Receivable or Receivables of such Obligor to the extent of any amounts then due and payable thereunder before being applied to any other indebtedness of such Obligor. 

ARTICLE VIII

non-Tax claim; provided, that nothing contained in this sentence shall limit the liability of such Originator or limit the recourse of any Purchase and Sale Indemnified Party to such Originator for any amounts otherwise specifically provided
to be paid by such Originator hereunder. Without limiting the foregoing indemnification, but subject to the limitations set forth in clauses (a), (b) and (c) of the previous sentence, each Originator, severally
for itself alone, shall indemnify each Purchase and Sale Indemnified Party for Purchase and Sale Relevant Amounts relating to or resulting from:

any Contract or any other Transaction Document to which it is a party or under the Contracts; 
 (g) any products liability,
environmental or other claim by an Obligor or other third party arising out of the goods or services which are the subject of any Sold Receivable generated by such Originator or the related Contract; 

  
 23 

 
  













 (h) the use of any Purchase Price paid to such Originator;

(i) Each of the Senior Interest Holders may, from time to time, at its sole discretion, without notice to the Holder, and

terms set forth in such Transaction Document); and (v) release its security interest in, or surrender, release or permit any substitution or exchange for all or any part of any rights or property securing any of the Senior Interests, or extend

of, or realization upon, the Senior Interests, or any thereof, or any security therefor; 
 (k) Each of the Senior Interest
Holders may, from time to time, on the terms and subject to the conditions set forth in the Transaction Documents to which such Persons are party, but without notice to the Holder, assign or transfer any or all of the Senior Interests, or any
interest therein; and, notwithstanding any such assignment or transfer or any subsequent assignment or transfer thereof, such Senior Interests shall be and remain Senior Interests for the purposes of these Subordination Provisions, and every
immediate and successive assignee or transferee of any of the Senior Interests or of any interest of such assignee or transferee in the Senior Interests shall be entitled to the benefits of these Subordination Provisions to the same extent as if
such assignee or transferee were the assignor or transferor; and 
 (1) These Subordination Provisions constitute a
continuing offer from the Holder to all Persons who become the holders of, or who continue to hold, Senior Interests; and these Subordination Provisions are made for the benefit of the Senior Interest Holders, and the Administrator may proceed to
enforce such provisions on behalf of each of such Persons. 
 10. No Waiver; No Petition. (a) No failure or delay on the part of
the Originator in exercising any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. No amendment,
modification or waiver of, or consent with respect to, any provision of this Company Note shall in any event be effective unless (i) the same shall be in writing and signed and delivered by the Company and the Holder and (ii) the
Administrator shall have consented thereto in writing. 
 (b) The Holder hereby agrees that it will not (i) institute against, join any
other Person in instituting against or take any action, direct or indirect, in furtherance or contemplation of instituting against, the Company any bankruptcy, insolvency, winding up, dissolution, receivership, conservatorship or other similar
proceeding or action or (ii) exercise any right of set-off or recoupment, or assert any counterclaim, against the Company in each case so long as there shall not have elapsed one year and one day since the Final Termination Date has occurred.

 11. Maximum Interest. Notwithstanding anything in this Company Note to the contrary, the Company shall never be required to pay
unearned interest on any amount outstanding hereunder and shall never be required to pay interest on the principal amount outstanding hereunder at a rate in excess of the maximum nonusurious interest rate that may be contracted for, charged or
received under applicable federal or state law (such maximum rate being herein called the “Highest Lawful Rate”). If the effective rate of interest which would otherwise by payable under this Company Note would exceed the Highest
Lawful Rate, or if the holder of this Company Note shall receive any unearned interest or shall receive monies that are deemed to constitute interest which would increase the effective rate of interest payable by the 

  
 Exhibit A- 5 

 
  













 Company under this Company Note to a rate in excess of the Highest Lawful Rate, then (i) the amount of
interest which would otherwise be payable by the Company under this Company Note shall be reduced to the amount allowed by applicable law, and (ii) any unearned interest paid by the Company or any interest paid by the Company in excess of the
Highest Lawful Rate shall be refunded to the Company. Without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received by the Originator under this Company Note that are made for the purpose of
determining whether such rate exceeds the Highest Lawful Rate applicable to the Originator (such Highest Lawful Rate being herein called the “Originator’s Maximum Permissible Rate”) shall be made, to the extent permitted by
usury laws applicable to the Originator (now or hereafter enacted), by amortizing, prorating and spreading in equal parts during the actual period during which any amount has been outstanding hereunder all interest at any time contracted for,
charged or received by the Originator in connection herewith. If at any time and from time to time (i) the amount of interest payable to the Originator on any date shall be computed at the Originator’s Maximum Permissible Rate pursuant to
the provisions of the foregoing sentence and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to the Originator would be less than the amount of interest payable to the Originator computed
at the Originator’s Maximum Permissible Rate, then the amount of interest payable to the Originator in respect of such subsequent interest computation period shall continue to be computed at the Originator’s Maximum Permissible Rate until
the total amount of interest payable to the Originator shall equal the total amount of interest which would have been payable to the Originator if the total amount of interest had been computed without giving effect to the provisions of the
foregoing sentence. 
 12. Governing Law. THIS COMPANY NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK (WITHOUT REFERENCE TO ITS CONFLICTS OF LAW PROVISIONS (OTHER THAN §5-1401 AND §5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW, WHICH SHALL APPLY HERETO)). 

13. Captions. Paragraph captions used in this Company Note are for convenience only and shall not affect the meaning or interpretation
of any provision of this Company Note.
