(g)    all books and records of such Originator to the extent related to any of the foregoing, and all rights, remedies, powers, privileges, title and interest (but not obligations) in and to each Lock-Box and all Lock-Box Accounts, into which any Collections or other proceeds with respect to such Receivables may be deposited, and any related investment property acquired with any such Collections or other proceeds (as such term is defined in the applicable UCC); and

(h)    all Collections and other proceeds (as defined in the UCC) of any of the foregoing that are or were received by such Originator on or after the Cut-Off Date, including,

without limitation, all funds which either are received by such Originator, the Buyer or the Servicer from or on behalf of the Obligors in payment of any amounts owed (including, without limitation, invoice price, finance charges, interest and all other charges) in respect of any of the above Receivables or are applied to such amounts owed by the Obligors (including, without limitation, any insurance payments that such Originator, the Buyer or the Servicer applies in the ordinary course of its business to amounts owed in respect of any of the above Receivables, and net proceeds of sale or other disposition of repossessed goods or other collateral or property of the Obligors in respect of any of the above Receivables or any other parties directly or indirectly liable for payment of such Receivables).

All purchases and contributions hereunder shall be made without recourse, but shall be made pursuant to, and in reliance upon, the representations, warranties and covenants of the Originators set forth in this Agreement. No obligation or liability to any Obligor on any Receivable is intended to be assumed by the Buyer hereunder, and any such assumption is expressly disclaimed. The property, proceeds and rights described in clauses (c) through (h) above, including with respect to any Contributed Receivable, are herein referred to as the “Related Rights”, and the Buyer’s foregoing commitment to purchase Receivables and Related Rights is herein called the “Purchase Facility.”

As used herein, “Cut-Off Date” means (a) with respect to each Originator party hereto on the date hereof, March 31, 2015, and (b) with respect to any Originator that first becomes a party hereto after the date hereof, the calendar day prior to the date on which such Originator becomes a party hereto or such other date as the Buyer and such Originator agree to in writing.

SECTION 1.2    Timing of Purchases.

(a)    Closing Date Purchases. Effective on the Closing Date, each Originator hereby sells to the Buyer, and the Buyer hereby purchases, such Originator’s entire right, title and interest in, to and under (i) each Receivable (other than Contributed Receivables) that existed and was owing to such Originator at the Cut-Off Date, (ii) each Receivable (other than Contributed Receivables) generated by such Originator from and including the Cut-Off Date, to and including the Closing Date, and (iii) all Related Rights with respect thereto.

(b)    Subsequent Purchases. After the Closing Date, until the Purchase and Sale Termination Date, each Receivable and the Related Rights generated by each Originator shall be, and shall be deemed to have been, sold or contributed, as applicable, by such Originator to the Buyer immediately (and without further action) upon the creation of such Receivable.

SECTION 1.3    Consideration for Purchases. On the terms and subject to the conditions set forth in this Agreement, the Buyer agrees to make Purchase Price payments to the Originators and to reflect all capital contributions in accordance with Article III.

SECTION 1.4    Purchase and Sale Termination Date. The “Purchase and Sale Termination Date” shall be the earlier to occur of (a) the date the Purchase Facility is terminated pursuant to Section 8.2(a) and (b) the Final Payout Date.

SECTION 1.5    Intention of the Parties. It is the express intent of each Originator and the Buyer that each conveyance by such Originator to the Buyer pursuant to this Agreement of the Receivables, including without limitation, all Receivables, if any, constituting general intangibles as defined in the UCC, and all Related Rights be construed as a valid and perfected sale and absolute assignment or, in the case of Contributed Receivables, an absolute contribution and conveyance (in each case, without recourse except as provided herein), of such Receivables and Related Rights by such Originator to the Buyer (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 Buyer 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. However, if, contrary to the mutual intent of the parties, any conveyance of Receivables, including without limitation any Receivables constituting general intangibles as defined in the UCC, and all Related Rights is not construed to be both a valid and perfected sale and absolute assignment or, in the case of Contributed Receivables, an absolute contribution and conveyance, 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 such Originator, then, it is the intent of such Originator and the Buyer 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 Buyer as of the date of this Agreement, and such Originator hereby grants to the Buyer a security interest in, to and under all of such Originator’s right, title and interest in and to: (A) the Receivables and the Related Rights now existing and hereafter created by such Originator transferred or purported to be transferred hereunder, (B) all monies due or to become due and all amounts received with respect thereto and (C) all books and records of such Originator to the extent related to any of the foregoing.

SECTION 2.1    Purchase Report. On the Closing Date and on each date when an Information Package is due to be delivered under the Receivables Financing Agreement (each such date, a “Monthly Purchase Report Date”), the Servicer shall deliver to the Buyer and each Originator a report in substantially the form of Exhibit A (each such report being herein called a “Purchase Report”) setting forth, among other things:

(a)    Receivables purchased by the Buyer from each Originator, or contributed to the capital of the Buyer by NuStar Logistics, on the Closing Date (in the case of the Purchase Report to be delivered on the Closing Date);

(b)    Receivables purchased by the Buyer from each Originator, or contributed to the capital of the Buyer by NuStar Logistics, during the calendar month immediately preceding such Monthly Purchase Report Date (in the case of each subsequent Purchase Report); and

(c)    the calculations of reductions of the Purchase Price for any Receivables as provided in Section 3.3(a) and (b).

SECTION 2.2    Calculation of Purchase Price. The “Purchase Price” to be paid to each Originator in accordance with the terms of Article III for the Receivables and the Related Rights that are purchased hereunder from such Originator shall be determined in accordance with the following formula:

“Payment Date” means (i) the Closing Date and (ii) each Business Day thereafter that the Originators are open for business.

“Prime Rate” means a per annum rate equal to the “U.S. Prime Rate” as published in the “Money Rates” section of The Wall Street Journal or if such information ceases to be published in The Wall Street Journal, such other publication as determined by the Administrative Agent in its sole discretion.

SECTION 3.1    Initial Contribution of Receivables and Initial Purchase Price Payment.

(a)    On the Closing Date, NuStar Logistics shall, and hereby does, contribute to the capital of the Buyer Receivables and Related Rights consisting of each Receivable of NuStar Logistics that exists and is owing to NuStar Logistics on the Closing Date beginning with the oldest of such Receivables and continuing chronologically thereafter such that the equity (taking into account any cash contributions made on or prior to the Closing Date) held by NuStar Logistics in the Buyer, after giving effect to such contribution of Receivables (the value of which shall be determined based on the Purchase Price definition), shall be at least equal to the Required Capital Amount. Each Receivable contributed by NuStar Logistics to the capital of the Buyer pursuant to this Section 3.1(a) and Section 3.2 below is herein referred to as a “Contributed Receivable”.

(b)    On the terms and subject to the conditions set forth in this Agreement, the Buyer agrees to pay to each Originator the Purchase Price for the purchase to be made from such

Originator on the Closing Date (x) to the extent the Buyer has cash available therefor, partially in cash (in an amount to be agreed between the Buyer and such Originator and set forth in the initial Purchase Report) and, solely in the case of NuStar Logistics if elected by NuStar Logistics in its sole discretion, by accepting a contribution to the Buyer’s capital and (y) the remainder by issuing a promissory note in the form of Exhibit B to such Originator (each such promissory note, 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, each being herein called a “Subordinated Note”) with an initial principal amount equal to the remaining Purchase Price payable to such Originator not paid in cash or, in the case of NuStar Logistics, contributed to the Buyer’s capital.

SECTION 3.2    Subsequent Purchase Price Payments. On each Payment Date subsequent to the Closing Date, on the terms and subject to the conditions set forth in this Agreement, the Buyer shall pay the Purchase Price to each Originator for the Receivables and the Related Rights generated by such Originator on such Payment Date as follows:

(a)    First, in cash to each Originator to the extent the Buyer has cash available therefor (and such payment is not prohibited under the Receivables Financing Agreement);

(b)    Second, solely in the case of NuStar Logistics, if elected by NuStar Logistics in its sole discretion, to the extent any portion of the Purchase Price remains unpaid, by accepting a contribution of such Receivable and the Related Rights to its capital in an amount equal to such remaining unpaid portion of such Purchase Price designated as a contribution to Buyer’s capital; and

(c)    Third, to the extent any portion of the Purchase Price remains unpaid, the principal amount outstanding under the applicable Subordinated Note shall be automatically increased by an amount equal to the lesser of (x) such remaining unpaid portion of such Purchase Price and (y) the maximum increase in the principal balance of the applicable Subordinated Note that could be made without rendering the Buyer’s Net Worth less than the Required Capital Amount;

provided, however, that if more than one Originator is selling Receivables to the Buyer on the date of such purchase, the Buyer shall make cash payments among the Originators in such a way as to minimize to the greatest extent practicable the aggregate principal amounts outstanding under the Subordinated Notes; provided, further, however, that the foregoing shall not be construed to require NuStar Logistics to make any capital contribution to the Buyer.

“Net Worth” has the meaning set forth under “Borrower’s Net Worth” in the Receivables Financing Agreement.

All amounts paid by the Buyer to any Originator shall be allocated first to the payment of accrued and unpaid interest on the Subordinated Note of such Originator and second to the repayment of the principal outstanding on the Subordinated Note of such Originator to the extent of such outstanding principal thereof as of the date of such payment before such amounts may be allocated for any other purpose. The Servicer shall make all appropriate record keeping entries with respect to each of the Subordinated Notes to reflect the foregoing payments and payments and reductions

made pursuant to Section 3.3, and the Servicer’s books and records shall constitute rebuttable presumptive evidence of the principal amount of, and accrued interest on, each of the Subordinated Notes at any time. Each Originator hereby irrevocably authorizes the Servicer to mark the Subordinated Notes “CANCELED” and to return such Subordinated Notes to the Buyer upon the final payment thereof after the occurrence of the Purchase and Sale Termination Date.

SECTION 3.3    Settlement as to Specific Receivables and Dilution.

(a)    If, (i) on the day of purchase of any Receivable from an Originator hereunder, any of the representations or warranties set forth in Sections 5.5, 5.12, 5.20, 5.22, 5.23, 5.26 or 5.27 are not true with respect to such Receivable or (ii) as a result of any action or inaction (other than solely as a result of the failure to collect such Receivable due to a discharge in bankruptcy or similar insolvency proceeding or other credit related reasons with respect to the relevant Obligor) of such Originator, on any subsequent day, any of such representations or warranties set forth in Sections 5.5, 5.12, 5.20, 5.22, 5.23, 5.26 or 5.27 is no longer true with respect to such Receivable, then the Purchase Price for such Receivable shall be reduced by an amount equal to the Outstanding Balance of such Receivable and shall be accounted to such Originator as provided in clause (c) below; provided, that if the Buyer thereafter receives payment on account of the Outstanding Balance of such Receivable, the Buyer promptly shall deliver such funds to such Originator.

(b)    If, on any day, the Outstanding Balance of any Receivable purchased or contributed hereunder is either (i) reduced or canceled as a result of (A) any defective, rejected or returned goods or services, any cash or other discount, or any failure by an Originator to deliver any goods or perform any services or otherwise perform under the underlying Contract or invoice, (B) any change in or cancellation of any of the terms of such Contract or invoice or any other adjustment by an Originator, the Servicer or the Buyer which reduces the amount payable by the Obligor on the related Receivable, (C) any rebates, warranties, allowances or charge-backs or (D) any setoff or credit in respect of any claim by the Obligor thereof (whether such claim arises out of the same or a related transaction or an unrelated transaction), or (ii) subject to any specific dispute, offset, counterclaim or defense whatsoever (except the discharge in bankruptcy of the Obligor thereof), then the Purchase Price with respect to such Receivable shall be reduced by the amount of such net reduction or dispute and shall be accounted to such Originator as provided in clause (c) below.

(c)    Any reduction in the Purchase Price of any Receivable pursuant to clause (a) or (b) above shall be applied as a credit for the account of the Buyer against the Purchase Price of Receivables subsequently purchased by the Buyer from such Originator hereunder; provided, however if, on such day, there have been no purchases of Receivables from such Originator (or insufficiently large purchases of Receivables) to create a Purchase Price sufficient to so apply such credit against, the amount of such credit:

(i)    to the extent of any outstanding principal balance under the Subordinated Note payable to such Originator shall be deemed to be a payment under, and shall be deducted from the principal amount outstanding under, the Subordinated Note payable to such Originator; and

(ii)    after making any deduction pursuant to clause (i) above, shall be paid in cash to the Buyer by such Originator in the manner and for application as described in the following proviso;     

provided, further, that at any time (x) when an Event of Default or an Unmatured Event of Default exists under the Receivables Financing Agreement or (y) on or after the Purchase and Sale Termination Date, the amount of any such credit shall be paid by such Originator to the Buyer in cash by deposit of immediately available funds into a Lock-Box Account for application by the Servicer to the same extent as if Collections of the applicable Receivable in such amount had actually been received on such date.

SECTION 3.4    Reconveyance of Receivables. In the event that the Purchase Price of a Receivable has been reduced to zero, and the credit for such reduction has been applied pursuant to Section 3.3, the Buyer shall reconvey such Receivable to such Originator, without representation or warranty, but free and clear of all liens, security interests, charges, and encumbrances created by the Buyer.

SECTION 4.1    Conditions Precedent to Initial Purchase. The initial purchase hereunder is subject to the condition precedent that the Buyer, the Administrative Agent (as the Buyer’s assignee) and each Group Agent shall have received, on or before the Closing Date, the following, each (unless otherwise indicated) dated the Closing Date, and each in form and substance satisfactory to the Buyer and the Administrative Agent (as the Buyer’s assignee) and each Group Agent:

Upon the creation of each new Receivable sold, contributed or otherwise conveyed or purported to be conveyed hereunder and on the Closing Date for then existing Receivables, the Buyer shall have a valid and perfected first priority ownership or security interest in each Receivable sold or conveyed to it hereunder, free and clear of any Adverse Claim.

SECTION 5.23    Perfection Representations.

(a)    This Agreement creates a valid and continuing ownership or security interest (as defined in the applicable UCC) in the Originator’s right, title and interest in, to and under the Receivables and Related Rights which (A) security interest has been perfected and is enforceable against creditors of and purchasers from such Originator and (B) will be free of all Adverse Claims.

The facts regarding such Originator, the Receivables sold by it hereunder, the Related Security and the related matters set forth or assumed in each of the opinions of counsel delivered in connection with this Agreement and the Transaction Documents are true and correct in all material respects.

SECTION 5.26    Enforceability of Contracts. Each Contract related to any Receivable sold or contributed by such Originator hereunder is effective to create, and has created, a legal, valid and binding obligation of the related Obligor to pay the outstanding balance of such Receivable, enforceable against the Obligor in accordance with its terms, without being subject to any defense, deduction, offset or counterclaim and such Originator has performed its obligations under such Contract in all material respects.

SECTION 5.27    Nature of Pool Receivables. All Pool Receivables: (i) were originated by such Originator in the ordinary course of its business, (ii) were sold to Buyer for fair consideration and reasonably equivalent value and (iii) represent all, or a portion of the purchase price of merchandise, insurance or services within the meaning of Section 3(c)(5)(A) of the Investment Company Act.

SECTION 5.28    Compliance with Applicable Laws. Each Originator is in compliance with the requirements of all laws, rules and regulations applicable to its property or business operations, except in such instance where (i) any failure to comply therewith, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect or (ii) the requirement to comply therewith is being contested in good faith.

(c)    Conduct of Business; Preservation of Existence. Each Originator will carry on and conduct its business in substantially the same manner and in substantially the same fields of enterprise as it is presently conducted and will do all things necessary to preserve and keep in full force and effect its existence and, except where the failure to do so would not reasonably be expected to have a Material Adverse Effect, its franchises, authority to do business in each jurisdiction in which its business is conducted, licenses, patents, trademarks, copyrights and other proprietary rights; provided however, that nothing in this paragraph (c) shall prevent any transaction permitted by paragraph (o) below or not otherwise prohibited by this Agreement or any other Transaction Document.

The Originators will not cause any Lock-Box Bank to violate the terms of any Lock-Box Agreement. The Originators shall not permit funds other than Affiliate Collections, Collections on Pool Receivables and other Collateral to be deposited into any Lock-Box Account. If such funds are nevertheless deposited into any Lock-Box Account, the Originators (or the Servicer on its behalf) will, within two (2) Business Days, identify and transfer such funds to the appropriate Person entitled to such funds. The Originators will not, and will not permit any other Person, to commingle Collections in any Lock-Box Account with any other funds to which the Buyer (or the Administrative Agent, the Group Agents or the Lenders, as the Buyer’s assignees) is entitled other than Affiliate Collections. The Originators shall only add (or permit the Servicer to add) a Lock-Box Account (or a related Lock-Box), or a Lock-Box Bank to those listed on Schedule II to the Receivables Financing Agreement, if the Administrative Agent has received notice of such addition and an executed and acknowledged copy of a Lock-Box Agreement (or an amendment thereto) in form and substance acceptable to the Administrative Agent from the applicable Lock-Box Bank. The Originators shall only terminate (or permit the Servicer to terminate) a Lock-Box Bank or close a Lock-Box Account (or a related Lock-Box) with the prior written consent of the Administrative Agent.

(ii)    each Originator will, at all times, maintain such books and records necessary to (a) identify Affiliate Collections received from time to time by such Originator, if any, and (b) segregate such Affiliate Collections from other property of the Originators; provided, however, that segregation of such Affiliate Collections shall not be required unless a Level 2 Ratings Event or an Event of Default has occurred and is continuing;

(iii)    on each Business Day, the Originators shall provide such information with respect to Affiliate Collections deposited into each Lock-Box Account (and any related Lock-Box) as reasonably requested by the Buyer or the Administrative Agent;

(iv)    upon the occurrence of a Level 2 Ratings Event, the Originators shall instruct the obligor of each Affiliate Receivable to cease remitting payments with respect to all Affiliate

Receivables to any Lock-Box Account or Lock-Box and to instead remit payments with respect thereto to any other account or lock-box (other than a Lock-Box Account or Lock-Box) from time to time identified to such obligor; and

(v)    at all times during the continuation of a Level 2 Ratings Event (i) the Originators shall not permit Affiliate Collections to be deposited into any Lock-Box or Lock-Box Account, (ii) if Affiliate Collections are nevertheless deposited into any Lock-Box or Lock-Box Account, the Originators (or the Servicer on its behalf) will within two (2) Business Days identify and transfer such funds to the appropriate Person entitled to such funds and (iii) the Originators will not, and will not permit any other Person, to commingle Collections or other funds to which the Buyer (or the Administrative Agent, the Group Agents or the Lenders, as the Buyer’s assignees) is entitled, with any Affiliate Collections.

(g)    Sales, Liens, etc. Except as otherwise provided herein, no Originator will sell, assign (by operation of law or otherwise) or otherwise dispose of, or create or suffer to exist any Adverse Claim upon (including, without limitation, the filing of any financing statement) or with respect to, any Pool Receivable or other Related Rights, or assign any right to receive income in respect thereof.

(h)    Extension or Amendment of Pool Receivables. Except as otherwise permitted by the Receivables Financing Agreement, no Originator will, or will permit the Servicer to, alter the delinquency status or adjust the Outstanding Balance or otherwise modify the terms of any Pool Receivable in any material respect, or amend, modify or waive, in any material respect, any term or condition of any related Contract; provided, however that any Originator may modify or permit the Servicer or any Originator to modify any Contract so long as the Contract Amendment Conditions are then satisfied with respect to such Contract. Each Originator shall at its expense, timely and fully perform and comply in all material respects with all provisions, covenants and other promises required to be observed by it under the Contracts related to the Pool Receivables, and timely comply in all material respects with the Credit and Collection Policy with regard to each Pool Receivable and the related Contract.

(i)    Fundamental Changes. Each Originator shall not make any change in such Originator’s name, location or making any other change in such Originator’s identity or corporate structure that could impair or otherwise render any UCC financing statement filed in connection with this Agreement or the Receivables Financing Agreement “seriously misleading” as such term (or similar term) is used in the applicable UCC, in each case, unless the Buyer, the Administrative Agent and each Group Agent have each (A) received 30 days’ prior notice thereof, (B) consented in writing thereto (such consent not to be unreasonably withheld), (C) received executed copies of all documents, certificates and opinions (including, without limitation, opinions relating to bankruptcy and UCC matters) as the Buyer or the Administrative Agent shall reasonably request and (D) been reasonably satisfied that all other action to perfect and protect the interests of the Buyer and the Administrative Agent, on behalf of the Lenders, in and to the Receivables to be sold by it hereunder and other Related Rights, as reasonably requested by the Buyer or the Administrative Agent shall have been taken by, and at the expense of, such Originator (including the filing of any

UCC financing statements, the receipt of certificates and other requested documents from public officials and all such other actions required pursuant to Section 7.3).

(j)    Change in Credit and Collection Policy. No Originator will make, or direct the Servicer to make, any material change in the Credit and Collection Policy without the prior written consent of the Administrative Agent and the Majority Group Agents (such consent not to be unreasonably withheld or delayed).

(k)    Records. Each Originator will maintain and implement (or cause the Servicer to maintain and implement) administrative and operating procedures (including an ability to recreate records evidencing Pool Receivables and related Contracts in the event of the destruction of the originals thereof), and keep and maintain (or cause the Servicer to keep and maintain) all documents, books, records, computer tapes and disks and other information reasonably necessary or advisable for the collection of all Pool Receivables (including records adequate to permit the daily identification of each Pool Receivable and all Collections of and adjustments to each existing Pool Receivable).

(l)    Ownership Interest, Etc. Each Originator shall (and shall cause the Servicer to), at its expense, take all action necessary or reasonably desirable to establish and maintain a valid and enforceable ownership or security interest in the Pool Receivables, the Related Rights and Collections with respect thereto, and a first priority perfected security interest in the Collateral, in each case free and clear of any Adverse Claim, in favor of the Buyer (and the Administrative Agent (on behalf of the Lenders), as the Buyer’s assignee), including taking such action to perfect, protect or more fully evidence the interest of the Buyer (and the Administrative Agent (on behalf of the Lenders), as the Buyer’s assignee) as the Buyer, the Administrative Agent or any Group Agent may reasonably request. In order to evidence the security interests of the Administrative Agent under this Agreement, such Originator shall, from time to time take such action, or execute and deliver such instruments as may be necessary (including, without limitation, such actions as are reasonably requested by the Administrative Agent) to maintain and perfect, as a first-priority interest, the Administrative Agent’s security interest in the Receivables, Related Security and Collections. Such Originator shall, from time to time and within the time limits established by law, prepare and present to the Administrative Agent for the Administrative Agent’s authorization and approval, all financing statements, amendments, continuations or initial financing statements in lieu of a continuation statement, or other filings necessary to continue, maintain and perfect the Administrative Agent’s security interest as a first-priority interest. The Administrative Agent’s approval of such filings shall authorize such Originator to file such financing statements under the UCC without the signature of such Originator, any other Originator or the Administrative Agent where allowed by Applicable Law. Notwithstanding anything else in the Transaction Documents to the contrary, such Originator shall not have any authority to file a termination, partial termination, release, partial release, or any amendment that deletes the name of a debtor or excludes collateral of any such financing statements filed in connection with the Transaction Documents, without the prior written consent of the Administrative Agent.

(m)    Further Assurances. Each Originator hereby authorizes and hereby agrees from time to time, at its own expense, promptly to execute (if necessary) and deliver all further

instruments and documents, and to take all further actions, that may be necessary or desirable, or that the Buyer or the Administrative Agent may reasonably request, to perfect, protect or more fully evidence the purchases and contributions made hereunder or under the Receivables Financing Agreement and/or security interest granted pursuant to the Receivables Financing Agreement or any other Transaction Document, or to enable the Buyer or the Administrative Agent (on behalf of the Lenders) to exercise and enforce their respective rights and remedies hereunder, under the Receivables Financing Agreement or under any other Transaction Document. Without limiting the foregoing, such Originator hereby authorizes, and will, upon the request of the Buyer or the Administrative Agent, at such Originator’s own expense, execute (if necessary) and file such financing statements or continuation statements, or amendments thereto, and such other instruments and documents, that may be necessary or desirable, or that the Buyer or Administrative Agent may reasonably request, to perfect, protect or evidence any of the foregoing.

(n)    Transaction Information.

SECTION 6.2    Separateness Covenants. Each Originator hereby acknowledges that this Agreement and the other Transaction Documents are being entered into in reliance upon the Buyer’s identity as a legal entity separate from such Originator and its Affiliates. Therefore, from and after the date hereof, each Originator shall take all reasonable steps necessary to make it apparent to third

Persons that the Buyer is an entity with assets and liabilities distinct from those of such Originator and any other Person, and is not a division of such Originator, its 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, such Originator shall take such actions as shall be required in order that:

(a)    such Originator shall not be involved in the day to day management of the Buyer;

(b)    such Originator shall maintain separate records and books of account from the Buyer and otherwise will observe corporate formalities and, to the extent that it renders or otherwise furnishes services to the Buyer, it will be compensated by the Buyer for such services;

(c)    the financial statements and books and records of such Originator shall be prepared after the date of creation of the Buyer to reflect and shall reflect the separate existence of the Buyer; provided, that the Buyer’s assets and liabilities may be included in a consolidated financial statement issued by an Affiliate of the Buyer; provided, however, that any such consolidated financial statement or the notes thereto shall make clear that the Buyer’s assets are not available to satisfy the obligations of such Affiliate;

(d)    except as permitted by the Receivables Financing Agreement, (i) such Originator shall maintain its assets (including, without limitation, deposit accounts) separately from the assets (including, without limitation, deposit accounts) of the Buyer and (ii) such Originator’s assets, and records relating thereto, have not been, are not, and shall not be, commingled with those of the Buyer;

(e)    such Originator shall not act as an agent for the Buyer (except in the capacity of Servicer or a Sub-Servicer);

(g)    such Originator shall not pay any liabilities of the Buyer out of its own funds or assets;

(h)    such Originator shall maintain an arm’s-length relationship with the Buyer;

(i)    such Originator shall not assume or guarantee or become obligated for the debts of the Buyer or hold out its credit as being available to satisfy the obligations of the Buyer;

(l)    such Originator shall identify and hold itself out as a separate and distinct entity from the Buyer;

(m)    such Originator shall correct any known misunderstanding respecting its separate identity from the Buyer;

(n)    such Originator shall not enter into, or be a party to, any transaction with the Buyer, except in the ordinary course of its business and on terms which are intrinsically fair and not less favorable to it than would be obtained in a comparable arm’s-length transaction with an unrelated third party;

(o)    such Originator shall not pay the salaries of the Buyer’s employees, if any; and

(p)    to the extent not already covered in paragraphs (a) through (o) above, such Originator shall comply and/or act in accordance with all of the other separateness covenants set forth in Section 8.03 of the Receivables Financing Agreement.

SECTION 7.1    Rights of the Buyer. Each Originator hereby authorizes the Buyer, the Servicer or their respective designees or assignees under the Receivables Financing Agreement (including, without limitation, the Administrative Agent) to take any and all steps in such Originator’s name necessary or desirable, in their respective determination, to collect all amounts due under any and all Receivables sold, contributed or otherwise conveyed or purported to be conveyed by it hereunder, including, without limitation, endorsing the name of such Originator on checks and other instruments representing Collections and enforcing such Receivables and the provisions of the related Contracts that concern payment and/or enforcement of rights to payment; provided, however, the Administrative Agent shall not take any of the foregoing actions unless an Event of Default has occurred and is continuing.

SECTION 7.2    Responsibilities of the Originators. Anything herein to the contrary notwithstanding:

(a)    Each Originator shall perform its obligations hereunder, and the exercise by the Buyer or its designee of its rights hereunder shall not relieve such Originator from such obligations.

(b)    None of the Buyer, the Servicer, the Lenders, the Group Agents or the Administrative Agent shall have any obligation or liability to any Obligor or any other third Person with respect to any Receivables, Contracts related thereto or any other related agreements, nor shall the Buyer, the Servicer, the Lenders, the Group Agents or the Administrative Agent be obligated to perform any of the obligations of such Originator thereunder.

(c)    Each Originator hereby grants to the Administrative Agent an irrevocable power-of-attorney, with full power of substitution, coupled with an interest, during the occurrence and continuation of an Event of Default to take in the name of such Originator all steps necessary

or advisable to endorse, negotiate or otherwise realize on any writing or other right of any kind held or transmitted by such Originator or transmitted or received by the Buyer (whether or not from such Originator) in connection with any Receivable sold, contributed or otherwise conveyed or purported to be conveyed by it hereunder or Related Right.

SECTION 7.3    Further Action Evidencing Purchases. On or prior to the Closing Date, each Originator shall mark its master data processing records evidencing Pool Receivables and Contracts with a legend, acceptable to the Buyer and the Administrative Agent, evidencing that the Pool Receivables have been transferred in accordance with this Agreement and none of the Originators or Servicer shall change or remove such notation without the consent of the Buyer and the Administrative Agent. 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 Buyer, the Servicer, the Administrative Agent or any Group Agent may reasonably request in order to perfect, protect or more fully evidence the Receivables and Related Rights purchased by or contributed to the Buyer hereunder, or to enable the Buyer to exercise or enforce any of its rights hereunder or under any other Transaction Document. Without limiting the generality of the foregoing, upon the request of the Buyer, the Administrative Agent or any Group Agent, such Originator will execute (if applicable), authorize and file such financing or continuation statements, or amendments thereto or assignments thereof, and such other instruments or notices, as may be necessary or appropriate.

Each Originator hereby authorizes the Buyer or its designee or assignee (including, without limitation, the Administrative Agent) to file one or more financing or continuation statements, and amendments thereto and assignments thereof, relative to all or any of the Receivables and Related Rights sold or otherwise conveyed or purported to be conveyed by it hereunder and now existing or hereafter generated by such Originator. If any Originator fails to perform any of its agreements or obligations under this Agreement, the Buyer or its designee or assignee (including, without limitation, the Administrative Agent) may (but shall not be required to) itself perform, or cause the performance of, such agreement or obligation, and the expenses of the Buyer or its designee or assignee (including, without limitation, the Administrative Agent) incurred in connection therewith shall be payable by such Originator.

SECTION 7.4    Application of Collections. Any payment by an Obligor in respect of any indebtedness owed by it to any 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 Administrative Agent) or the Administrative Agent, be applied as a Collection of any Receivable or Receivables of such Obligor to the extent of any amounts then due and payable thereunder (such application to be made starting with the oldest outstanding Receivable or Receivables) before being applied to any other indebtedness of such Obligor.

SECTION 7.5    Performance of Obligations. Each Originator shall (i) perform all of its obligations under the Contracts related to the Receivables generated by such Originator to the same extent as if interests in such Receivables had not been transferred hereunder, and the exercise by the Buyer or the Administrative Agent of its rights hereunder shall not relieve any Originator from any such obligations and (ii) pay when due any taxes, including, without limitation, any sales taxes

payable in connection with the Receivables generated by such Originator and their creation and satisfaction.

SECTION 8.1    Purchase and Sale Termination Events. Each of the following events or occurrences described in this Section 8.1 shall constitute a “Purchase and Sale Termination Event” (each event which with notice or the passage of time or both would become a Purchase and Sale Termination Event being referred to herein as an “Unmatured Purchase and Sale Termination Event”):

(a)    the Termination Date shall have occurred;

(b)    any Originator shall fail to make when due any payment or deposit to be made by it under this Agreement or any other Transaction Document to which it is a party and such failure shall remain unremedied for three (3) Business Days;

(c)    any representation or warranty made or deemed to be made by any Originator (or any of its officers) under or in connection with this Agreement, any other Transaction Documents to which it is a party, or any other information or report delivered pursuant hereto or thereto shall prove to have been incorrect or untrue in any material respect when made or deemed made or delivered; provided, that such circumstance shall not constitute a Purchase and Sale Termination Event pursuant to this clause (c) if either such representation or warranty, or such information or report, is part of an Information Package, is corrected promptly (but not later than five (5) Business Days) after the Originator has knowledge or receives notice thereof; provided, further that no breach of a representation or warranty set forth in Sections 5.5, 5.12, 5.20, 5.22, 5.25 or 5.26 shall constitute a Purchase and Sale Termination Event pursuant to this clause (c) if credit has been given for a reduction of the Purchase Price, the outstanding principal balance of the applicable Subordinated Note, if any, has been reduced or the applicable Originator has made a cash payment to the Buyer, in any case, as required pursuant to Section 3.3(c) with respect to such breach;

(d)    any Originator shall fail to perform or observe any other term, covenant or agreement contained in this Agreement or any other Transaction Document to which it is a party on its part to be performed or observed and such failure shall continue unremedied for thirty (30) days after the such Originator has knowledge or receives written notice thereof; or

(e)    any Insolvency Proceeding shall be instituted against any Originator and such proceeding shall remain undismissed or unstayed for a period of thirty (30) consecutive days or any of the actions sought in such proceeding (including the entry of an order for relief against, or the appointment of a receiver, trustee, custodian or other similar official for, it or for any substantial part of its property) shall occur.

SECTION 8.2    Remedies.

(a)    Optional Termination. Upon the occurrence and during the continuation of a Purchase and Sale Termination Event, the Buyer (and not the Servicer), with the prior written consent of the Administrative Agent shall have the option, by notice to the Originators (with a copy to the Administrative Agent and the Group Agents), to declare the Purchase Facility terminated.

(b)    Remedies Cumulative. Upon any termination of the Purchase Facility pursuant to Section 8.2(a), the Buyer (and the Administrative Agent as Buyer’s assignee) shall have, in addition to all other rights and remedies under this Agreement, all other rights and remedies provided under the UCC of each applicable jurisdiction and other Applicable Laws, which rights shall be cumulative.

(h)    any failure of such Originator to perform any its duties or obligations in accordance with the provisions hereof and of each other Transaction Document related to Pool Receivables or to timely and fully comply with the Credit and Collection Policy in regard to each Pool Receivable;

(i)    the commingling of Collections of Pool Receivables at any time with other funds;

(j)    the Servicer’s failure or delay to provide any Obligor with an invoice or other evidence of indebtedness (so long as NuStar or an Affiliate of NuStar is the Servicer);

(k)    any investigation, litigation or proceeding (actual or threatened) related to this Agreement or any other Transaction Document or in respect of any Pool Receivable or any Related Rights;

(l)    any claim brought by any Person other than a Purchase and Sale Indemnified Party arising from any activity by such Originator or any Affiliate of such Originator in servicing, administering or collecting any Pool Receivable;

(n)    any dispute, claim, offset or defense (other than discharge in bankruptcy of the Obligor) of the Obligor to the payment of any Pool Receivable (including, without limitation, a defense based on such Pool 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 goods or the rendering of services related to such Pool Receivable or the furnishing or failure to furnish any such goods or services or other similar claim or defense not arising from the financial inability of any Obligor to pay undisputed indebtedness;

(o)    any product liability claim arising out of or in connection with goods or services that are the subject of any Receivable generated by such Originator;

(p)    any tax or governmental fee or charge, all interest and penalties thereon or with respect thereto, and all out-of-pocket costs and expenses, including without limitation Attorney Costs in defending against the same, which are required to be paid by reason of the purchase or ownership of the Receivables generated by such Originator or any Related Rights connected with any such Receivables; or

(q)    any action taken by the Administrative Agent in accordance with Applicable Law as attorney-in-fact for such Originator pursuant to this Agreement or any other Transaction Document;

provided that such indemnity shall not be available to any Purchase and Sale Indemnified Party to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction in a final and nonappealable judgment to have resulted solely from the gross negligence or willful misconduct of a Purchase and Sale Indemnified Party, (y) result from a claim brought by Originator, NuStar Energy or an Affiliate for breach of such Purchase and Sale Indemnified Party’s obligations under this Agreement or under any other Transaction Document, if the Originator, NuStar Energy or an Affiliate has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction or (z) constitute recourse with respect to a Pool Receivable by reason of the bankruptcy or insolvency, or the financial or credit condition or financial default, of the related Obligor.

If for any reason the foregoing indemnification is unavailable to any Purchase and Sale Indemnified Party or insufficient to hold it harmless, then the Originators, jointly and severally, shall contribute to the amount paid or payable by such Purchase and Sale Indemnified Party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative economic interests of such Originator and its Affiliates, on the one hand, and such Purchase and Sale Indemnified Party, on the other hand, in the matters contemplated by this Agreement as well as the relative fault of such Originator and its Affiliates and such Purchase and Sale Indemnified Party with respect to such loss, claim, damage or liability and any other relevant equitable considerations.

No notice to or demand on the Buyer, the Servicer or any Originator in any case shall entitle it to any notice or demand in similar or other circumstances. No waiver or approval by the Buyer, the Administrative Agent or the Servicer under this Agreement shall, except as may otherwise be stated in such waiver or approval, be applicable to subsequent transactions. No waiver or approval under this Agreement shall require any similar or dissimilar waiver or approval thereafter to be granted hereunder.

The Buyer covenants and agrees, and the Originator and any other holder of this Subordinated Note (collectively, the Originator and any such other holder are called the “Holder”), by its acceptance of this Subordinated Note, likewise covenants and agrees on behalf of itself and any Holder, that the payment of the principal amount of and interest on this Subordinated Note is hereby expressly subordinated in right of payment to the payment and performance of the Senior Interests to the extent and in the manner set forth in the following clauses of this paragraph 9:

(a)    No payment or other distribution of the Buyer’s assets of any kind or character, whether in cash, securities, or other rights or property, shall be made on account of this Subordinated Note except to the extent such payment or other distribution is (i) permitted under Section 8.01(r) of the Receivables Financing Agreement or (ii) made pursuant to clause (a) or (b) of paragraph 6 of this Subordinated Note;

(b)    In the event of any dissolution, winding up, liquidation, readjustment, reorganization or other similar event relating to the Buyer, whether voluntary or involuntary, partial or complete, and whether in bankruptcy, insolvency or receivership proceedings, or upon an assignment for the benefit of creditors, or any other marshalling of the assets and liabilities of the Buyer or any sale of all or substantially all of the assets of the Buyer other than as permitted by the Purchase and Sale Agreement (such proceedings being herein collectively called “Bankruptcy Proceedings”), the Senior Interests shall first be paid and performed in full and in cash before the Originator shall be entitled to receive and to retain any payment or distribution in respect of this Subordinated Note. In order to implement the foregoing: (i) all payments and distributions of any kind or character in respect of this Subordinated Note to which the Holder would be entitled except for this clause (b) shall be made directly to the Administrative Agent (for the benefit of the Senior Interest Holders); (ii) the Holder shall promptly file a claim or claims, in the form required in any Bankruptcy Proceedings, for the full outstanding amount of this Subordinated Note, and shall use commercially reasonable efforts to cause said claim or claims to be approved and all payments and other distributions in respect thereof to be made directly to the Administrative Agent (for the benefit of the Senior Interest Holders) until the Senior Interests shall have been paid and performed in full and in cash; and (iii) the Holder hereby irrevocably agrees that the Administrative Agent (acting on behalf of the Lenders), may in the name of the Holder or otherwise, demand, sue for, collect, receive and receipt for any and all such payments or distributions, and file, prove and vote or consent in any such Bankruptcy Proceedings with respect to any and all claims of the Holder relating to this Subordinated Note, in each case until the Senior Interests shall have been paid and performed in full and in cash;

(c)    In the event that the Holder receives any payment or other distribution of any kind or character from the Buyer or from any other source whatsoever, in respect of this Subordinated Note, other than as expressly permitted by the terms of this Subordinated Note, such payment or other distribution shall be received in trust for the Senior Interest Holders and shall be turned over by the Holder to the Administrative Agent (for the benefit of the Senior Interest Holders) forthwith. The Holder will mark its books and records so as clearly to indicate that this Subordinated Note is subordinated in accordance with the terms hereof. All payments and distributions received by the Administrative Agent in respect of this Subordinated Note, to the extent received in or converted into cash, may be applied by the Administrative Agent (for the benefit of the Senior Interest Holders) first to the payment of any and all expenses (including Attorney Costs) paid or incurred by the Senior Interest Holders in enforcing these Subordination Provisions, or in endeavoring to collect or realize upon this Subordinated Note, and any balance thereof shall, solely as between the Originator and the Senior Interest Holders, be applied by the Administrative Agent (in the order of application set forth in Section 4.01(a) of the Receivables Financing Agreement) toward the payment of the Senior Interests; but as between the Buyer and its creditors, no such payments or distributions of any kind or character shall be deemed to be payments or distributions in respect of the Senior Interests;

(d)    Notwithstanding any payments or distributions received by the Senior Interest Holders in respect of this Subordinated Note, while any Bankruptcy Proceedings are pending the Holder shall not be subrogated to the then existing rights of the Senior Interest Holders in respect of the Senior Interests until the Senior Interests have been paid and performed in full and in cash. If no Bankruptcy Proceedings are pending, the Holder shall only be entitled to exercise any subrogation rights that it may acquire (by reason of a payment or distribution to the Senior Interest Holders in respect of this Subordinated Note) to the extent that any payment arising out of the exercise of such rights would be permitted under Section 8.01(r) of the Receivables Financing Agreement;

(e)    These Subordination Provisions are intended solely for the purpose of defining the relative rights of the Holder, on the one hand, and the Senior Interest Holders on the other hand. Nothing contained in these Subordination Provisions or elsewhere in this Subordinated Note is intended to or shall impair, as between the Buyer, its creditors (other than the Senior Interest Holders) and the Holder, the Buyer’s obligation, which is unconditional and absolute, to pay the Holder the principal of and interest on this Subordinated Note as and when the same shall become due and payable in accordance with the terms hereof or to affect the relative rights of the Holder and creditors of the Buyer (other than the Senior Interest Holders);

(f)    The Holder shall not, until the Senior Interests have been paid and performed in full and in cash, (i) cancel, waive, forgive, transfer or assign, or commence legal proceedings to enforce or collect, or subordinate to any obligation of the Buyer, howsoever created, arising or evidenced, whether direct or indirect, absolute or contingent, or now or hereafter existing, or due or to become due, other than the Senior Interests, this Subordinated Note or any rights in respect hereof or (ii) convert this Subordinated Note into an equity

interest in the Buyer, unless the Holder shall, in either case, have received the prior written consent of the Administrative Agent;

(g)    The Holder shall not, without the advance written consent of the Administrative Agent and each Lender, commence, or join with any other Person in commencing, any Bankruptcy Proceedings with respect to the Buyer until at least one year and one day shall have passed since the Senior Interests shall have been paid and performed in full and in cash;

(h)    If, at any time, any payment (in whole or in part) of any Senior Interest is rescinded or must be restored or returned by a Senior Interest Holder (whether in connection with Bankruptcy Proceedings or otherwise), these Subordination Provisions shall continue to be effective or shall be reinstated, as the case may be, as though such payment had not been made;

(i)    Each of the Senior Interest Holders may, from time to time, at its sole discretion, without notice to the Holder, and without waiving any of its rights under these Subordination Provisions, take any or all of the following actions: (i) retain or obtain an interest in any property to secure any of the Senior Interests; (ii) retain or obtain the primary or secondary obligations of any other obligor or obligors with respect to any of the Senior Interests; (iii) extend or renew for one or more periods (whether or not longer than the original period), alter or exchange any of the Senior Interests, or release or compromise any obligation of any nature with respect to any of the Senior Interests; (iv) amend, supplement, amend and restate, or otherwise modify any Transaction Document as permitted by the terms of any 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 or renew for one or more periods (whether or not longer than the original period), or release, compromise, alter or exchange any obligations of any nature of any obligor with respect to any such rights or property;

(j)    The Holder hereby waives: (i) notice of acceptance of these Subordination Provisions by any of the Senior Interest Holders; (ii) notice of the existence, creation, non-payment or non-performance of all or any of the Senior Interests; and (iii) all diligence in enforcement, collection or protection 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

(l)    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 Administrative Agent may proceed to enforce such provisions on behalf of each of such Persons.

10.General. No failure or delay on the part of the Originator in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power or right preclude any other or further exercise thereof or the exercise of any other power or right. No amendment, modification or waiver of, or consent with respect to, any provision of this Subordinated Note shall in any event be effective unless (i) the same shall be in writing and signed and delivered by the Buyer and the Holder and (ii) all consents required for such actions under the Transaction Documents shall have been received by the appropriate Persons.

11.Maximum Interest. Notwithstanding anything in this Subordinated Note to the contrary, the Buyer 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 be payable under this Subordinated Note would exceed the Highest Lawful Rate, or if the holder of this Subordinated 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 Buyer under this Subordinated Note to a rate in excess of the Highest Lawful Rate, then (i) the amount of interest which would otherwise be payable by the Buyer under this Subordinated Note shall be reduced to the amount allowed by Applicable Law, and (ii) any unearned interest paid by the Buyer or any interest paid by the Buyer in excess of the Highest Lawful Rate shall be refunded to the Buyer. Without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received by the Originator under this Subordinated 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.    No Negotiation. This Subordinated Note is not negotiable.

13.    Governing Law. THIS SUBORDINATED NOTE, INCLUDING THE RIGHTS AND DUTIES OF THE PARTIES HERETO, SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (INCLUDING SECTIONS 5-1401 AND 5-1402 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK, BUT WITHOUT REGARD TO ANY OTHER CONFLICTS OF LAW PROVISIONS THEREOF).

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

IN WITNESS WHEREOF, the Buyer has caused this Subordinated Note to be executed as of the date first written above.
