(b) if any Yield Period would otherwise end on a day that is not a Business Day, such Yield Period shall be extended to the next succeeding Business Day, unless the result of such extension would be to extend such Yield Period into another calendar month, in which event such Yield Period shall end on the immediately preceding Business Day;

(c) any Yield Period that begins on the last Business Day of a calendar month (or on a day for which there is no numerically corresponding day in the calendar month at the end of such Yield Period) shall end on the last Business Day of a calendar month;

(d) the Seller may not select any Yield Period that ends after the Commitment Termination Date; and

(e) there shall be outstanding at any one time no more than 10 Yield Periods in the aggregate.

(a) Except as otherwise expressly provided herein, all terms of an accounting or financial nature shall be construed in accordance with GAAP, as in effect from time to time; provided that if any Transaction Party notifies the Agent that it requests an amendment to any provision hereof to eliminate the effect of any change occurring after the date hereof in GAAP or in the application thereof on the operation of such provision (or if the Agent notifies the Transaction Parties that the Required Purchasers request an amendment to any provision hereof for such purpose), then such provision shall be interpreted on the basis of GAAP as in effect and applied immediately before such change shall have become effective until such notice shall have been withdrawn or such provision amended in accordance herewith.

(b) Except where the context requires otherwise, the definitions in Section 1.1 shall apply equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words “include”, “includes” and “including” shall be deemed to be followed by the phrase “without limitation”. Unless otherwise stated, references to Sections, Articles, Schedules and Exhibits made herein are to Sections, Articles, Schedules or Exhibits, as the case may be, of this Agreement. “Writing”, “written” and comparable terms refer to printing, typing and other means of reproducing words in a visible form. References to any agreement or contract are to such agreement or contract as amended, modified or supplemented from time to time in accordance with the terms hereof and thereof. References to any Person include the successors and permitted assigns of such Person.

(c) All terms used in Article 9 of the UCC in the State of New York and not specifically defined herein are used herein as defined in such Article 9.

Unless otherwise stated in this Agreement, in the computation of a period of time from a specified date to a later specified date, the word “from” means “from and including”, the words “to” and “until” each means “to but excluding” and the word “through” means “through and including”.

On the terms and conditions herein set forth, each Purchaser severally agrees to make Purchases (i) on the Closing Date and from time to time thereafter on any Business Day during the period from the Closing Date to the Termination Date and (ii) in an aggregate amount for such Purchaser not to exceed at any time outstanding such Purchaser’s Commitment; provided, however, that no Purchaser shall be obligated to make any Purchase to the extent that, after giving effect to such Purchase, the Capital then outstanding would exceed the Maximum Capital. Purchases shall be made by the Purchasers simultaneously and ratably in accordance with their respective Commitments.

(a) Each Purchase of a Receivable Interest by the Purchasers shall be made on notice from the Seller to the Agent, given not later than 11:00 a.m. (New York time) (i) on the third Business Day before the date of such Purchase in the case of the Purchase of any Receivable Interest initially bearing Yield at the Applicable LIBO Rate and (ii) on the Business Day of such Purchase in the case of the Purchase of any Receivable Interest initially bearing Yield at the Applicable Base Rate. Each such notice of a proposed Purchase of a Receivable Interest (a “Notice of Purchase”) shall be by telephone (confirmed promptly thereafter in writing) or facsimile, in substantially the form of Exhibit F hereto, and shall specify the requested aggregate amount of such Purchase to be paid to the Seller and the requested Business Day of such Purchase. Each Purchase of any Receivable Interest under this Section 2.2 shall be in an aggregate amount which is an integral multiple of $1,000,000 and which is not less than the lesser of $10,000,000 and the remaining available balance of the Commitments.

(b) The Agent shall give each Purchaser prompt notice of such notice of such proposed Purchase, the date of such Purchase, and the amount of such Purchaser’s Capital Investment in connection with such Purchase, by telephone or telefax. On the date of such Purchase, each Purchaser shall, upon satisfaction of the applicable conditions set forth in Section 3.2, make available to the Agent its Ratable Portion of the aggregate amount of such Purchase by deposit of such Ratable Portion in same day funds to the Agent’s Account, and, after receipt by the Agent of such funds, the Agent shall cause such funds to be made immediately available to the Seller at the Seller’s Account.

(d) Unless the Agent shall have received notice from a Purchaser prior to the date of any Purchase that such Purchaser will not make available to the Agent such Purchaser’s Ratable Portion of such Purchase, the Agent may assume that such Purchaser has made such Ratable Portion available to the Agent on the date of such Purchase in accordance with Section 2.2(b), and the Agent may, in reliance upon such assumption, make available to the Seller on such date a corresponding amount. However, if the Agent has received such notice from such Purchaser, the Agent may not make such assumption and

may not make available to the Seller on such date such corresponding amount. If and to the extent that such Purchaser (other than a Purchaser that has delivered to the Agent a notice of the type described in the two immediately preceding sentences) shall not have made such Ratable Portion available to the Agent and the Agent has made such Ratable Portion available to the Seller, such Purchaser and the Seller severally agree to pay (to the extent not repaid by the Seller or such Purchaser, respectively) to the Agent promptly on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Seller until the date such amount is repaid to the Agent, at (i) in the case of the Seller, the Yield applicable to such amount and (ii) in the case of such Purchaser, the Federal Funds Rate. If such Purchaser shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Purchaser’s Ratable Portion of such Purchase for purposes of this Agreement.

(e) The failure of any Purchaser to make available such Purchaser’s Ratable Portion of any Purchase shall not relieve any other Purchaser of its obligation, if any, hereunder to make available such other Purchaser’s Ratable Portion of such Purchase on the date of such Purchase, but no Purchaser shall be responsible for the failure of any other Purchaser to make available such other Purchaser’s Ratable Portion of such Purchase on the date of any Purchase. Nothing herein shall prejudice any rights that the Seller may have against any Purchaser as a result of any default by such Purchaser hereunder.

(a) On the terms and subject to the conditions contained in this Agreement, the Swing Purchaser agrees to make, in U.S. Dollars, Purchases (each a “Swing Purchase”) otherwise committed to the Seller hereunder from time to time on any Business Day during the period from the Closing Date until the Termination Date representing an aggregate Capital Investment at any time outstanding (together with the aggregate outstanding Capital Investment relating to any other Purchase made by the Swing Purchaser hereunder in its capacity as the Swing Purchaser) not to exceed the Swing Purchase Sublimit; provided, however, that at no time shall the Swing Purchaser make any Swing Purchase to the extent that, after giving effect to such Swing Purchase, the Capital then outstanding would exceed the Maximum Capital.

(b) In order to request a Swing Purchase, the Seller may telephone the Agent (to be promptly confirmed thereafter in writing) or send the Agent by telecopy (or by electronic mail or similar means) a duly completed request in substantially the form of Exhibit G, setting forth the requested amount and date of such Swing Purchase (a “Swing Purchase Request”), to be received by the Agent not later than 12:00 p.m. (New York time) on the day of the proposed purchase. The Agent shall promptly notify the Swing Purchaser of the details of the requested Swing Purchase. Subject to the terms of this Agreement, the Swing Purchaser may make the Capital Investment in connection with such Swing Purchase available to the Agent and, in turn, the Agent shall make such amounts available to the Seller on the date of the relevant Swing Purchase Request. The Swing Purchaser shall not make any Swing Purchase in the period commencing on the first Business Day after it receives written notice from the Agent or any Purchaser that one or more of the conditions precedent contained in Section 3.2 shall not on such date be satisfied, and ending when such conditions are satisfied. The Swing Purchaser shall not otherwise be required to determine that, or take notice whether, the conditions precedent set forth in Section 3.2 have been satisfied in connection with the making of any Swing Purchase. The Capital Investment relating to each Swing Purchase shall be in an aggregate amount of not less than $100,000.

(c) The Swing Purchaser shall notify the Agent in writing (which writing may be a telecopy or electronic mail) weekly, by no later than 10:00 a.m. (New York time) on the first Business Day of each week, of the aggregate amount of its Capital Investments at such time in respect of Swing Purchases.

(d) The Swing Purchaser may demand at any time that each Purchaser pay to the Agent, for the account of the Swing Purchaser, in the manner provided in clause (e) below, such Purchaser’s Ratable Portion of all or a portion of the Swing Purchaser’s Capital Investments at such time in respect of Swing Purchases, which demand shall be made through the Agent, shall be in writing and shall specify the amount of the Capital Investments demanded to be so reduced; provided that if the aggregate amount of the Swing Purchaser’s Capital Investments in respect of Swing Purchases on the last Business Day of any week exceeds $5,000,000, then the Swing Purchaser shall make such demand to the Agent on such last Business Day of such week and require each Purchaser to pay to the Agent, for the account of the Swing Purchaser, on such last Business Day of such week such Purchaser’s Ratable Portion of the Swing Purchaser’s Capital Investments in respect of Swing Purchases then outstanding.

(e) The Agent shall forward each notice referred to in clause (c) above and each demand referred to in clause (d) above to each Purchaser on the day such notice or such demand is received by the Agent (except that any such notice or demand received by the Agent after 2:00 p.m. (New York time) on any Business Day or any such demand received on a day that is not a Business Day shall not be required to be forwarded to the Purchasers by the Agent until the next succeeding Business Day), together with a statement prepared by the Agent specifying the amount of each Purchaser’s Ratable Portion of the aggregate amount of the Capital Investments in respect of Swing Purchases stated to be outstanding in such notice or demanded to be paid pursuant to such demand, and, notwithstanding whether or not the conditions precedent set forth in Section 3.2 and Section 2.1 shall have been satisfied (which conditions precedent the Purchasers hereby irrevocably waive), each Purchaser shall, before 12:00 noon (New York time) on the Business Day next succeeding the date of such Purchaser’s receipt of such notice or demand, make available to the Agent, in immediately available funds, for the account of the Swing Purchaser, the amount specified in such statement; provided, however, that notwithstanding anything to the contrary in the foregoing, no Purchaser shall be obligated to purchase a Ratable Portion of, or otherwise pay any sum in respect of, the Capital Investments in respect of a Swing Purchase to the extent that the purchase by such Purchaser of a Ratable Portion of, or payment of other sum in respect of, the Capital Investments in respect of such Swing Purchase would cause such Purchaser’s aggregate Capital Investment to exceed its Commitment. Upon such purchase by a Purchaser, such Purchaser shall, except as provided in clause (f), be deemed to have made a Purchase with a Capital Investment equal to the amount actually paid by such Purchaser. The Agent shall use such funds to reduce the Swing Purchaser’s Capital Investments in respect of Swing Purchases.

(f) Upon the occurrence of an Event of Termination under Section 7.1(f), each Purchaser shall acquire, without recourse or warranty, an undivided participation in the Swing Purchaser’s Capital Investments in respect of each Swing Purchase otherwise required to be repaid by such Purchaser pursuant to clause (e) above, which participation shall be in an amount equal to such Purchaser’s Ratable Portion of the Swing Purchaser’s Capital Investments in respect of such Swing Purchase, by paying to the Swing Purchaser on the date on which such Purchaser would otherwise have been required to make a payment in respect of such Swing Purchaser’s Capital Investments pursuant to clause (e) above, in immediately available funds, an amount equal to such Purchaser’s Ratable Portion of such Swing Purchaser’s Capital Investments. If all or part of such amount is not in fact made available by such Purchaser to the Swing Purchaser on such date, the Swing Purchaser shall be entitled to recover any such unpaid amount on demand from such Purchaser together with interest accrued from such date at the Federal Funds Rate for the first Business Day after such payment was due and thereafter at the Applicable Base Rate.

(g) From and after the date on which any Purchaser (i) is deemed to have made a Purchase pursuant to clause (e) above with respect to any Swing Purchase or (ii) purchases an undivided participation interest in the Swing Purchaser’s Capital Investments in respect of a Swing Purchase pursuant to clause (f) above, the Swing Purchaser shall promptly distribute to such Purchaser such

Purchaser’s Ratable Portion of all payments in respect of Capital Investments and Yield received by the Swing Purchaser on account of such Swing Purchase other than those received from a Purchaser pursuant to clause (e) or (f) above.

Section 2.4 Termination or Reduction of the Commitments; Voluntary Reductions of Capital.

(a) The Seller may, upon at least 3 Business Days’ notice to the Agent, and so long as, after giving effect to a proposed reduction, no Event of Termination or Potential Event of Termination, would exist, terminate in whole or reduce in part, the unused portions of the Commitments of the Purchasers; provided, however, that for purposes of this Section 2.4, the unused portions of the Commitments of the Purchasers shall be computed as (a) the Total Commitments immediately prior to giving effect to such termination or reduction less (b) the outstanding Capital at the time of such computation; provided, further, that each such partial reduction of the unused portions of the Commitments (x) shall be in an amount equal to at least $5,000,000 and shall be an integral multiple of $1,000,000 in excess thereof, (y) shall be made ratably among the Purchasers’ Commitments according to each Purchaser’s Ratable Portion and (z) shall reduce the Total Commitments in an amount equal to each such reduction.

(b) The Seller may, upon at least 3 Business Days’ notice to the Agent, reduce the outstanding Capital in whole or in part; provided that each such partial reduction of Capital shall be in a minimum amount of $5,000,000 and an integral multiple of $1,000,000.

(a) On the date of Purchase of any Receivable Interest, such Receivable Interest shall be initially computed, after giving effect to such Purchase, as of the close of business of the Servicer on such date. Thereafter until the Termination Date, such Receivable Interest shall be automatically recomputed as of the close of business of the Servicer on each day (other than a Liquidation Day).

(b) Such Receivable Interest shall remain constant from the time as of which any such computation or recomputation is made until the time as of which the next such recomputation, if any, shall be made. Each Receivable Interest, as computed as of the day immediately preceding the Termination Date, shall remain constant at all times on and after the Termination Date; and any Special Receivable Interest, as computed as of the Termination Date, shall remain constant at all times on and after the Termination Date.

(c) Such Receivable Interest shall become zero at such time as the Purchasers of such Receivable Interest shall have received the accrued Yield for such Receivable Interest, shall have recovered the Capital Investment of such Receivable Interest, and shall have received payment of all other amounts payable by the Seller to such Purchasers, and the Servicer shall have received the accrued Servicer Fee for such Receivable Interest.

(a) On each Business Day (other than a Liquidation Day or a day on which a Triggering Event exists) the Servicer shall, out of Collections of Pool Receivables received on such Business Day:

(i) first, pay to the Servicer (if the Servicer is not Lyondell or an Affiliate or Subsidiary of Lyondell) or the Agent and the Purchasers, as applicable, an amount in U.S. Dollars equal to the Servicer Fee, the Yield, the Unused Commitment Fee, the Agent’s Fee and any other Obligations of the Seller due and payable on such day;

(ii) second, distribute to the Agent for the account of the Swing Purchaser an amount in U.S. Dollars equal to that amount, if any, then required to be applied to reduce the Swing Purchaser’s Capital Investments in respect of Swing Purchases to zero;

(iii) third, if such day is the second Business Day following the date on which a Seller Report is or is required to be delivered, a Shortfall Condition exists as of the last day of the period covered by such Seller Report, and the Agent does not receive an updated Seller Report demonstrating that a Shortfall Condition does not exist on such second Business Day, distribute to the Agent for the account of the Purchasers an amount in U.S. Dollars equal to that amount, if any, which would be required to reduce Capital so that the aggregate Receivable Interests would not, after giving effect to such application and the Collections of Pool Receivables and the addition of new Pool Receivables on such day and the resulting automatic recomputation of such Receivable Interests pursuant to Section 2.5 as of the end of such day, exceed 100%; provided that (x) the Agent shall apply such amount, first, to reduce all Capital Investments as to which Yield is determined on the basis of the Adjusted Base Rate and (y) second, to reduce all Capital Investments as to which Yield is determined on the basis of the Adjusted LIBO Rate; provided that in lieu of immediately reducing the Capital Investments as to which Yield is determined on the basis of the Adjusted LIBO Rate, the Agent, at the direction of the Seller, may transfer such amount to the Cash Assets Account and such amount shall be deemed to reduce Capital by the amount so held pending application thereof to reduce Capital Investments as to which Yield is calculated on the basis of the Adjusted LIBO Rate on the last day of each Yield Period applicable thereto (occurring in chronological order); provided, further, however, that if the Agent subsequently receives a request from the Servicer for a withdrawal of all or a portion of such amounts that are then held in the Cash Assets Account and a Seller Report demonstrating that a Shortfall Condition, after giving effect to such requested withdrawal, does not exist, then the Agent shall release such amounts to the Servicer for further application under this Section 2.6(a);

(iv) fourth, distribute to the Agent for the account of the Purchasers of each Receivable Interest an amount in U.S. Dollars equal to that amount, if any, then required to be applied to reduce the Capital Investment of such Receivable Interest pursuant to the notice of the Seller delivered under Section 2.4(b);

(v) fifth, distribute to the Agent for deposit into the Cash Assets Account such amount as the Seller, at its option, has specified to the Agent, which amount shall be deemed to reduce Capital by a corresponding amount; provided, however, that if the Agent subsequently receives a request from the Servicer for a withdrawal of all or a portion of such amounts that are then held in the Cash Assets Account and a Seller Report demonstrating that a Shortfall Condition, after giving effect to such requested withdrawal, does not exist, then the Agent shall release such amounts to the Servicer for further application under this Section 2.6(a).

(vi) sixth, distribute to the Servicer (if the Servicer is Lyondell or an Affiliate or Subsidiary of Lyondell) the accrued Servicer Fee to the extent then due and payable; and

(vii) seventh, reinvest the remainder of such Collections, for the benefit of the Purchasers, which reinvestment shall result in (x) an automatic recomputation of the undivided percentage interest represented by such Receivable Interest pursuant to Section 2.5 as of the end of such day and (y) the payment of such remainder to the Seller; provided, however, that to the extent the Agent or any Purchaser shall be required for any reason to pay over any amount representing Collections which have been previously reinvested for the benefit of such Purchaser pursuant hereto, such amount shall be deemed not to have been so reinvested but rather to have been retained by the Seller and paid over for the account of such Purchaser and, notwithstanding any provision herein to the contrary, such Purchaser shall have a claim for such amount;

provided, however, that if sufficient funds are not available to fund all payments to be made in respect of any amounts described in any of clauses second, third, fourth, fifth and sixth above, the available funds being applied with respect to any such amounts (unless otherwise specified in such clause) shall be allocated to the payment of the amounts referred to in such clause ratably, based on the proportion of the Servicer’s, the Agent’s or the Purchasers’ interest in the aggregate outstanding amounts described in such clause.

(b) Subject to Section 2.6 and Section 2.7, all amounts in the Concentration Account shall be automatically transferred to the Seller’s Account, and payments and distributions by the Servicer pursuant to Section 2.6(a) shall be made from funds so transferred to the Seller’s Account.

(a) On each Business Day (other than a Liquidation Day) on which a Triggering Event exists, the Agent (and not the Servicer) shall, out of Collections of Pool Receivables received on such Business Day:

(i) first, pay to the Servicer (if the Servicer is not Lyondell or an Affiliate or Subsidiary of Lyondell), the Agent and the Purchasers, as applicable, an amount in U.S. Dollars equal to the Servicer Fee, the Yield, the Unused Commitment Fee, the Agent’s Fee and any other Obligations of the Seller due and payable on such day;

(ii) second, distribute to the Swing Purchaser an amount in U.S. Dollars necessary to reduce the Swing Purchaser’s Capital Investments in respect of Swing Purchases to zero;

(iii) third, distribute to the Purchasers an amount in U.S. Dollars necessary to reduce all Capital Investments to zero as follows: (1) first, to reduce all Capital Investments as to which Yield is determined on the basis of the Adjusted Base Rate and (2) second, to reduce all Capital Investments as to which Yield is determined on the basis of the Adjusted LIBO Rate, provided that in lieu of immediately reducing the Capital Investments as to which Yield is determined on the basis of the Adjusted LIBO Rate, the Agent, at the direction of the Seller, may transfer such amount to the Cash Assets Account and such amount shall be deemed to reduce Capital by the amount so held pending application thereof to reduce Capital Investments as to which Yield is calculated on the basis of the Adjusted LIBO Rate on the last day of each Yield Period applicable thereto (occurring in chronological order); provided, further, however, that if the Agent subsequently receives a request from the Servicer or the Seller for a withdrawal of all or a portion of such amounts that are then held in the Cash Assets Account and either (I) the Agent receives a Seller Report demonstrating that a Shortfall Condition does not exist

and certifying that either the conditions to an Investment Event would be satisfied or a Triggering Event does not exist, in each case after giving effect to such requested withdrawal, or (II) the aggregate Capital is zero, then the Agent shall release such amounts for reinvestment and payment to the Seller;

(iv) fourth, distribute to the Purchasers of each Receivable Interest an amount in U.S. Dollars equal to that amount, if any, then required to be applied to reduce the Capital Investment of such Receivable Interest pursuant to the notice of the Seller delivered under Section 2.4(b);

(v) fifth, deposit into the Cash Assets Account such amount as the Seller, at its option, has specified to the Agent, which amount shall be deemed to reduce Capital (to the extent of any Capital then outstanding) by a corresponding amount; provided, however, that if the Agent subsequently receives a request from the Servicer or the Seller for a withdrawal of all or a portion of such amounts that are then held in the Cash Assets Account and a Seller Report demonstrating that a Shortfall Condition does not exist and certifying that either (x) the conditions to an Investment Event would be satisfied or (y) a Triggering Event ceases to exist, in each case after giving effect to such requested withdrawal, then the Agent shall release such amounts for further application under this Section 2.7(a);

(vi) sixth, distribute to the Servicer (if the Servicer is Lyondell or an Affiliate or Subsidiary of Lyondell) the accrued Servicer Fee to the extent then due and payable; and

(vii) seventh, reinvest the remainder of such Collections, for the benefit of the Purchasers, which reinvestment shall result in (x) the automatic recomputation of the undivided percentage interest represented by such Receivable Interest pursuant to Section 2.5 as of the end of such day and (y) the payment of such remainder to the Seller; provided, however, that to the extent the Agent or any Purchaser shall be required for any reason to pay over any amount representing Collections which have been previously reinvested for the benefit of such Purchaser pursuant hereto, such amount shall be deemed not to have been so reinvested but rather to have been retained by the Seller and paid over for the account of such Purchaser and, notwithstanding any provision herein to the contrary, such Purchaser shall have a claim for such amount;

provided, however, that if sufficient funds are not available to fund all payments to be made in respect of any amounts described in any of clauses first, second, third, fourth, fifth and sixth above, the available funds being applied with respect to any such amounts (unless otherwise specified in such clause) shall be allocated to the payment of the amounts referred to in such clause ratably, based on the proportion of the Servicer’s, the Agent’s or the Purchasers’ interest in the aggregate outstanding amounts described in such clause.

(b) During the existence of a Triggering Event (other than on a Liquidation Day), all amounts in the Concentration Account shall be automatically transferred to the Sweep Account, and payments and distributions by the Agent pursuant to Section 2.7(a) shall be made from funds in the Sweep Account.

On each Liquidation Day, the Agent shall transfer to the Sweep Account the Collections of Pool Receivables received on such day, and the Agent shall apply such Collections, and all amounts held in the Cash Assets Account, as follows:

(i) first, to pay Obligations of the Seller to the Agent under any Transaction Document in respect of any expense reimbursements, Cash Management Obligations or indemnities then due to the Agent;

(ii) second, to pay Obligations of the Seller to the Purchasers under any Transaction Document in respect of any expense reimbursements or indemnities then due to such Persons;

(iii) third, to the Servicer (if the Servicer is not Lyondell or an Affiliate or Subsidiary of Lyondell) in payment of the accrued Servicer Fee then due and payable, and to the Purchasers in payment of the accrued Unused Commitment Fees then due and payable;

(iv) fourth, to the Purchasers in payment of the accrued Yield then due and payable;

(v) fifth, to the Purchasers in reduction (to zero) of the Capital Investments in respect of each Receivable Interest;

(vi) sixth, to the Purchasers in ratable payment of any other Obligations owed by the Seller hereunder or under any other Transaction Document (except for the Servicer Fee);

(vii) seventh, to the Servicer (if the Servicer is Lyondell or an Affiliate or Subsidiary of Lyondell) in payment of the accrued Servicer Fee then due and payable; and

provided, however, that if sufficient funds are not available to fund all payments to be made in respect of any amounts described in any of clauses first, second, third, fourth, fifth, sixth and seventh above, the available funds being applied with respect to any such amounts (unless otherwise specified in such clause) shall be allocated to the payment of the amounts referred to in such clause ratably, based on the proportion of the Servicer’s, the Agent’s or the Purchasers’ interest in the aggregate outstanding amounts described in such clause.

(a) Except as set forth in clauses (a) and (b) below or as otherwise required by law or the underlying Contract, all Collections received from an Obligor of any Pool Receivable shall be applied to Pool Receivables then outstanding of such Obligor in the order of the age of such Pool Receivables, starting with the oldest such Pool Receivable, except if payment is designated by such Obligor for application to specific Pool Receivables.

(b) If, on any day, the Outstanding Balance of a Pool Receivable is either (x) reduced as a result of any defective, rejected or returned goods or services, any discount, or any adjustment by the Seller or any Originator, or (y) reduced or cancelled as a result of a setoff in respect of any claim by the Obligor thereof against the Seller or any Originator (whether such claim arises out of the same or a related transaction or an unrelated transaction), the Seller shall be deemed to have received on such day a Collection of such Receivable in the amount of such reduction or cancellation and shall make the payment required to be made by it in connection with such Collection on the day required by, and otherwise pursuant to, Section 5.1(i).

(c) If on any day (x) any of the representations or warranties in Section 4.1(h) is no longer true with respect to any Pool Receivable or (y) it is discovered that any Receivable that was included in the Net Receivables Pool Balance as an Eligible Receivable was not an Eligible Receivable at the time of such inclusion, the Seller shall be deemed to have received on such day a Collection in full of such Pool Receivable and shall make the payment required to be made by it in connection with such Collection on the day required by, and otherwise pursuant to, Section 5.1(i).

(a) All amounts to be paid or deposited by the Seller or the Servicer hereunder shall be paid or deposited in accordance with the terms hereof no later than 12:00 noon (New York time) on the day when due in U.S. Dollars in same day funds to the Agent’s Account. The Servicer or the Agent, as applicable, shall promptly thereafter cause to be distributed (i) like funds relating to the payment out of Collections in respect of Capital, Yield, Servicer Fee or other Obligations payable out of Collections, to the Purchasers (according to each Purchaser’s Ratable Portion) and the Servicer in accordance with the provisions of Section 2.6, 2.7, or 2.8, as applicable, and (ii) like funds relating to the payment by the Seller of other Obligations payable by the Seller hereunder, to the parties hereto for whose benefit such funds were paid (and if such funds are insufficient, such distribution shall be made, subject to Section 2.6, 2.7 or 2.8, as applicable, ratably in accordance with the respective amounts thereof). Upon the Agent’s acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 9.2, from and after the effective date specified in such Assignment and Acceptance, the Agent shall make all payments hereunder in respect of the interest assigned thereby to the Assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) The Seller shall, to the extent permitted by law, pay to the Agent interest on all amounts not paid or deposited when due hereunder (except for those amounts with respect to which Yield accrues) at 2.00% per annum above the Alternate Base Rate in effect from time to time, payable on demand, provided, however, that such interest rate shall not at any time exceed the maximum rate permitted by applicable law. Such interest shall be for the account of, and distributed by the Agent to, the applicable Purchasers ratably in accordance with their respective interests in such overdue amount.

(c) All computations of interest and all computations of Yield, Unused Commitment Fee and other per annum fees hereunder shall be made on the basis of a year of 360 days for the actual number of days (including the first but excluding the last day) elapsed.

(d) Unless the Agent shall have received notice from the Servicer or the Seller prior to the date on which any payment is due to the Purchasers hereunder that the Servicer or the Seller, as the case may be, will not make such payment in full, the Agent may assume that the Servicer or the Seller, as the case may be, has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Purchaser on such due date an amount equal to the amount then due such Purchaser. If and to the extent the Servicer or the Seller, as the case may be, shall

not have so made such payment in full to the Agent, each Purchaser shall repay to the Agent promptly on demand such amount distributed to such Purchaser together with interest thereon, for each day from the date such amount is distributed to such Purchaser until the date such Purchaser repays such amount to the Agent, at the Federal Funds Rate.

(a) All Capital Investments and the outstanding amount of all other Obligations hereunder shall bear a Yield, in the case of Capital Investments, on the amount thereof from the date such Capital Investments are made and, in the case of such other Obligations, from the date such other Obligations are due and payable until, in all cases, paid in full, at the Applicable Yield. Accrued Yield shall be payable on each Payment Date.

(b) The Seller shall pay the Agent such fees as are set forth in the Citicorp Fee Letter to which such Facility Agent is a party.

(c) The Seller shall pay to the Agent for remittance to the Servicer a fee (the “Servicer Fee”) of 0.50% per annum on the average daily aggregate Outstanding Balance of the Pool Receivables for the most recently completed month, from the date of the initial Purchase hereunder until the later of the Termination Date or the date on which Capital is reduced to zero, payable in arrears on the applicable Payment Date; provided, however, that, if at any time, the Servicer is not Lyondell or an Affiliate or Subsidiary of Lyondell, the Servicer shall be paid, as such fee, the greater of (i) such amount and (ii) 120% of its reasonable out-of-pocket costs and expenses incurred by it in servicing, administering and collecting the Pool Receivables; and, provided further, that such fee shall be payable only from Collections pursuant to, and subject to the priority of payment set forth in, Sections 2.6, 2.7 and 2.8.

(d) The Seller agrees to pay to each Purchaser an unused commitment fee on the actual daily amount by which the Commitment of such Purchaser exceeds such Purchaser’s Capital Investments (the “Unused Commitment Fee”) from the date hereof through the Termination Date at a rate of 0.50% per annum, payable in arrears (x) on the second Business Day of each calendar month, commencing on the first such Business Day following the Closing Date and (y) on the Termination Date.

Section 2.12 Special Provisions Governing Capital Investments at the Applicable LIBO Rate.

(a) Increased Costs. If, due to either (i) a change after the date hereof in Regulation D of the Board (to the extent any cost incurred pursuant to such regulation is not included in the calculation of Adjusted LIBO Rate), (ii) the introduction of or any change after the date hereof in or in the interpretation of any law or regulation (other than any law or regulation relating to taxes, as to which Section 2.14 shall govern) or (iii) the compliance with any guideline or request issued or made after the date hereof from any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to (or, in the case of Regulation D of the Board there shall be imposed a cost on) any Indemnified Party of agreeing to make or making any Purchase or maintaining any Receivable Interest (or interest therein) hereunder, then the Seller shall from time to time, within five Business Days following demand and delivery to the Seller of the certificate referred to in the last sentence of this Section 2.12(a) by such Indemnified Party (or by the Agent for the account of such Indemnified Party) (with a copy of such demand and certificate to the Agent), pay to the Agent for the account of such Indemnified Party additional amounts sufficient to compensate such Indemnified Party for such increased or imposed cost. Each Indemnified Party hereto agrees to use reasonable efforts promptly to notify the Seller of any event referred to in clause (i), (ii) or (iii) above, provided that the failure to give such notice shall not affect the rights of any Indemnified Party under this Section 2.12(a).

A certificate in reasonable detail as to the basis for and the amount of such increased cost, submitted to the Seller and the Agent by such Indemnified Party (or by the Agent for the account of such Indemnified Party) shall be conclusive and binding for all purposes, absent manifest error.

(b) Interest Rate Unascertainable, Inadequate or Unfair. In the event that (i) the Agent determines that adequate and fair means do not exist for ascertaining the applicable interest rates by reference to which the Adjusted LIBO Rate then being determined is to be fixed or (ii) the Required Purchasers notify the Agent that the Adjusted LIBO Rate for any Yield Period will not adequately reflect the cost to the Purchasers of making a Capital Investment or maintaining such Capital Investment for such Yield Period, the Agent shall forthwith so notify the Seller and the Purchasers, whereupon the Applicable Yield for such Capital Investment shall automatically, on the last day of the current Yield Period for such Capital Investment, convert into the Applicable Base Rate and the obligations of the Purchasers to make a Capital Investment or maintain a Capital Investment at the Applicable LIBO Rate shall be suspended until the Agent shall notify the Seller that the Required Purchasers have determined that the circumstances causing such suspension no longer exist.

(c) Illegality. Notwithstanding any other provision of this Agreement, if any Purchaser determines that the introduction of, or any change in or in the interpretation of, any law, treaty or governmental rule, regulation or order after the date of this Agreement shall make it unlawful, or any central bank or other Governmental Authority shall assert that it is unlawful, for any Purchaser to make a Capital Investment or maintain a Capital Investment at the Applicable LIBO Rate, then, on notice thereof and demand therefor by such Purchaser to the Seller through the Agent, (i) the obligation of such Purchaser to make a Capital Investment or maintain a Capital Investment at the Applicable LIBO Rate shall be suspended, and each such Purchaser shall make Capital Investments at the Applicable Base Rate and (ii) if the affected Capital Investments at the Applicable LIBO Rate are then outstanding, the Seller shall immediately convert each such Capital Investment into a Capital Investment at the Applicable Base Rate. If, at any time after a Purchaser gives notice under this Section 2.12(c), such Purchaser determines that it may lawfully make Capital Investments at the Applicable LIBO Rate, such Purchaser shall promptly give notice of that determination to the Seller and the Agent, and the Agent shall promptly transmit the notice to each other Purchaser. The Seller’s right to request, and such Purchaser’s obligation, if any, to make Capital Investments at the Applicable LIBO Rate shall thereupon be restored.

(d) Liquidation Costs. In addition to all amounts required to be paid by the Seller hereunder, the Seller shall compensate each Purchaser, within five Business Days following demand therefor, for all losses, expenses and liabilities (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Purchaser to fund or maintain such Purchaser’s Capital Investments at the Applicable LIBO Rate but excluding any loss of the Applicable Margin on the relevant Capital Investments) (each, a “Liquidation Cost”) that such Purchaser may sustain, and any customary fees that such Purchaser may impose, (i) if for any reason a proposed Capital Investment, conversion into or continuation of Capital Investments at the Applicable LIBO Rate does not occur on a date specified therefor in a Notice of Purchase given by the Seller or in a telephonic request by it for Purchase or a successive Yield Period does not commence after notice therefor is given hereunder, (ii) if for any reason any Capital Investment at the Applicable LIBO Rate is reduced (including mandatorily pursuant to Section 2.7 or 2.8) on a date that is not the last day of the applicable Yield Period, (iii) as a consequence of a required conversion of a Capital Investment at the Applicable LIBO Rate to Capital Investment at the Applicable Base Rate as a result of any of the events indicated in Section 2.12(c) above or (iv) as a consequence of any failure by the Seller to reduce Capital Investment at the Applicable LIBO Rate when required by the terms hereof. The Purchaser making demand for such compensation shall deliver to the Seller concurrently with such demand a written statement as to such losses, expenses and liabilities and fees, and this statement shall be conclusive as to the amount of compensation due to such Purchaser, absent manifest error.

If any Indemnified Party determines that either the introduction of or any change in or in the interpretation of any law or regulation after the date hereof or the compliance with any guideline or request issued or made after the date hereof from any central bank or other Governmental Authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Indemnified Party or any corporation controlling such Indemnified Party and that the amount of such capital is increased by or based upon the existence of such Indemnified Party’s commitment, if any, to purchase any Receivable Interest (or interest therein), or to maintain such Receivable Interest (or interest therein) hereunder, then, within five Business Days following demand and delivery to the Seller of the certificate referred to in the last sentence of this Section 2.13 by such Indemnified Party (or by the Agent for the account of such Indemnified Party) (with a copy of such demand and certificate to the Agent) the Seller shall pay to the Agent for the account of such Indemnified Party from time to time, as specified by such Indemnified Party, additional amounts sufficient to compensate such Indemnified Party or such corporation in the light of such circumstances, to the extent that such Indemnified Party reasonably determines such increase in capital to be allocable to the existence of any such commitment. Each Indemnified Party hereto agrees to use reasonable efforts promptly to notify the Seller of any event referred to in the first sentence of this Section 2.13, provided that the failure to give such notice shall not affect the rights of any Indemnified Party under this Section 2.13. A certificate in reasonable detail as to the basis for, and the amount of, such compensation submitted to the Seller and the Agent by such Indemnified Party (or by the Agent for the account of such Indemnified Party) shall be conclusive and binding for all purposes, absent manifest error.

(a) Any and all payments by the Seller hereunder or deposits from Collections hereunder shall be made, in accordance with Section 2.10, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Indemnified Party, (i) taxes that are imposed on its overall net income by the United States, (ii) taxes that are imposed on its overall net income, assets or net worth (and franchise taxes imposed in lieu thereof) by the state or foreign jurisdiction under the laws of which such Indemnified Party is organized or qualified to do business or in which such Indemnified Party holds any asset in connection with this Agreement or, in each case, any political subdivision thereof, and (iii) branch profits tax imposed by the United States of America or any similar tax imposed by any other jurisdiction in which any Indemnified Party is located (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or deposits from Collections hereunder being hereinafter referred to as “Taxes”). If the Seller or the Servicer or the Agent shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or deposit from Collections hereunder to any Indemnified Party, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.14) such Indemnified Party receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Seller or the Servicer or the Agent shall make such deductions and (iii) the Seller or the Servicer or the Agent shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, the Seller shall pay any present or future sales, stamp, documentary, excise, property or similar taxes, charges or levies that arise from any payment made hereunder or deposit from Collections hereunder or from the execution, delivery or registration of, performing under, or otherwise with respect to, this Agreement, the Receivables Sale Agreement or any other Transaction Document (hereinafter referred to as “Other Taxes”).

(c) The Seller shall indemnify each Indemnified Party for and hold it harmless against the full amount of Taxes and Other Taxes (including, without limitation, taxes of any kind imposed by any jurisdiction on amounts payable under this Section 2.14) imposed on or paid by such Indemnified Party and any liability (including penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be made within five Business Days from the date such Indemnified Party makes written demand therefor (with a copy to the Agent).

(d) Within 30 days after the date of any payment of Taxes, the Seller shall furnish to the Agent and each applicable Purchaser, at its address referred to in Section 11.3, the original or a certified copy of a receipt evidencing such payment or a certificate executed by a Responsible Officer of the Seller stating that such Taxes have been paid, together with evidence of such payment reasonably satisfactory to the Agent.

(e) Each Purchaser organized under the laws of a jurisdiction outside the United States shall, on or prior to the date of its execution and delivery of this Agreement in the case of each Initial Purchaser, and on the date of the Assignment or the Assignment and Acceptance pursuant to which it became a Purchaser in the case of each other Purchaser, and from time to time thereafter as requested in writing by the Seller (but only so long thereafter as such Purchaser remains lawfully able to do so), provide each of the Agent and the Seller with 2 original Internal Revenue Service forms W-8ECI or W-8BEN, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that such Purchaser is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement. If the forms provided by a Purchaser at the time such Purchaser first becomes a party to this Agreement indicate a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and until such Purchaser provides the appropriate form certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes for periods governed by such form; provided, however, that if, at the effective date of the Assignment or the Assignment and Acceptance pursuant to which an Assignee becomes a Purchaser hereunder, the Purchaser assignor was entitled to payments under subsection (a) of this Section 2.14 (after taking into account subsections (e) and (f) of this Section 2.14) in respect of United States withholding tax with respect to amounts paid hereunder at such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Taxes) United States withholding tax, if any, applicable with respect to such Assignee on such date. If any form or document referred to in this subsection (e) requires the disclosure of information, other than information necessary to compute the tax payable and information required on the date hereof by Internal Revenue Service form W-8ECI or W-8BEN or any successor or other form prescribed by the Internal Revenue Service, that the Purchaser reasonably considers to be confidential, the Purchaser shall give notice thereof to the Seller and shall not be obligated to include in such form or document such confidential information.

(f) For any period with respect to which a Purchaser has failed to provide the Seller with the appropriate form described in subsection (e) of this Section 2.14 (other than if such failure is due to a change in law occurring after the date on which a form originally was required to be provided or if such form otherwise is not required under subsection (e) of this Section 2.14), such Purchaser shall not be entitled to indemnification under subsection (a) or (c) of this Section 2.14 with respect to Taxes imposed by the United States by reason of such failure; provided, however, that should any Purchaser become subject to Taxes because of its failure to deliver a form required hereunder, the Seller shall take such steps as such Purchaser shall reasonably request to assist such Purchaser (at such Purchaser’s expense) to recover such Taxes.

If any Purchaser shall obtain any payment (whether voluntarily, involuntarily, through the exercise of any right of set-off or otherwise) on account of the Purchases made by it (other than with respect to payments due to such Purchaser pursuant to Section 2.12, 2.13 or 2.14) in excess of its Ratable Portion of payments on account of the Purchases obtained by all the Purchasers, such Purchaser shall forthwith purchase from the other Purchasers such interests in the Receivable Interests purchased by them as shall be necessary to cause such Purchaser to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such Purchaser, such purchase from each other Purchaser shall be rescinded and such other Purchaser shall repay to the Purchaser the purchase price to the extent of such recovery together with an amount equal to such other Purchaser’s Ratable Portion (according to the proportion of (a) the amount of such other Purchaser’s required repayment to (b) the total amount so recovered from the Purchaser) of any interest or other amount paid or payable by the Purchaser in respect of the total amount so recovered. The Seller agrees that any Purchaser so purchasing an interest in Receivable Interests from another Purchaser pursuant to this Section 2.15 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such interest in Receivable Interests as fully as if such Purchaser were the direct creditor of the Seller in the amount of such interest in Receivable Interests.

(a) The Seller may elect (i) at any time on any Business Day, to convert Capital Investments bearing Yield at the Applicable Base Rate (other than Swing Purchases) or any portion thereof to Capital Investments bearing Yield at the Applicable LIBO Rate and (ii) at the end of any applicable Yield Period, to convert Capital Investments bearing Yield at the Applicable LIBO Rate or any portion thereof into Capital Investments bearing Yield at the Applicable Base Rate or to continue such Capital Investments bearing Yield at the Applicable LIBO Rate or any portion thereof for an additional Yield Period; provided, however, that the aggregate amount of the Capital Investments bearing Yield at the Applicable LIBO Rate for each Yield Period must be in an amount of at least $10,000,000 or an integral multiple of $1,000,000 in excess thereof. Each conversion or continuation shall be allocated among the Capital Investments of each Purchaser in accordance with such Purchaser’s Receivable Interest. Each such election shall be in substantially the form of Exhibit H (a “Notice of Conversion or Continuation”) and shall be made by giving the Agent at least 3 Business Days’ prior written notice specifying (A) the amount and type of Capital Investment being converted or continued, (B) in the case of a conversion to or a continuation of Capital Investments bearing Yield at the Applicable LIBO Rate, the applicable Yield Period and (C) in the case of a conversion, the date of such conversion.

(b) The Agent shall promptly notify each Purchaser of its receipt of a Notice of Conversion or Continuation and of the options selected therein. Notwithstanding the foregoing, no conversion in whole or in part of Capital Investments bearing Yield at the Applicable Base Rate to Capital Investments bearing Yield at the Applicable LIBO Rate and no continuation in whole or in part of Capital Investments bearing Yield at the Applicable LIBO Rate upon the expiration of any applicable Yield Period shall be permitted at any time at which (i) a Potential Event of Termination or an Event of Termination shall have occurred and be continuing or (ii) the continuation of, or conversion into, a Capital Investment bearing Yield at the Applicable LIBO Rate would violate any provision of Section 2.12. If, within the time period required under the terms of this Section 2.16, the Agent does not receive a Notice of Conversion or Continuation from the Seller containing a permitted election to continue any Capital Investments bearing Yield at the Applicable LIBO Rate for an additional Yield Period or to convert any such Capital Investments, then, upon the expiration of the applicable Yield Period, such Capital Investments shall, subject to Section 3.2, be automatically continued as Capital Investments bearing Yield at the Applicable LIBO Rate with a Yield Period of one month. Each Notice of Conversion or Continuation shall be irrevocable.

Section 2.17 Duty to Mitigate; Assignment of Commitments Under Certain Circumstances.

(a) If any Indemnified Party claims any additional amounts payable pursuant to Section 2.12 or Section 2.13 or if the Seller is required to pay any additional amount to any Indemnified Party or any Governmental Authority for the account of any Purchaser pursuant to Section 2.14, then such Indemnified Party shall use reasonable efforts (consistent with legal and regulatory restrictions) to file any certificate or document, including, without limitation, any such certificate or document reasonably requested by the Seller, or to change the jurisdiction of the applicable office through which it holds or maintains its interest in the applicable Receivable Interest or to take other actions (including the filing of certificates or documents) known to it to be available if the making of such a filing or change or the taking of such other action would avoid the need for or reduce the amount of any such additional amounts which may thereafter accrue or avoid the circumstances giving rise to such exercise and would not, in the sole determination of such Indemnified Party, be otherwise disadvantageous to such Indemnified Party or its Receivable Interest.

(b) In the event that any Indemnified Party shall have delivered a notice or certificate pursuant to Section 2.12 or 2.13, or the Seller shall be required to make additional payments to any Indemnified Party under Section 2.14, the Seller shall have the right, with the assistance of the Agent, to designate a substitute bank or banks (which may be one or more of the Purchasers) mutually satisfactory to the Seller and the Agent (and the Swing Purchaser) to purchase for cash, pursuant to an Assignment and Acceptance, the outstanding Capital Investment of such Purchaser and assume the Commitment of such Purchaser, without recourse to or warranty by, or expense to, such Purchaser, for a purchase price equal to the amount of all of such Purchaser’s outstanding Capital Investment plus any accrued but unpaid Yield thereon and the accrued but unpaid fees for the account of such Purchaser hereunder plus such amount, if any, as would be payable pursuant to Section 2.12(d) if the outstanding Capital Investment of such Purchaser was prepaid in its entirety on the date of consummation of such assignment.

Section 2.18 Restricted Accounts; Investment of Amounts in the Cash Assets Account.

(a) The Agent shall have “control” (within the meaning of Section 9-104 of the UCC) of each of the Restricted Accounts.

(b) Funds held in the Cash Assets Account may, until withdrawn or otherwise applied pursuant hereto, be invested and reinvested in such Liquid Investments as the Seller may request from time to time; provided that, if an Event of Termination shall have occurred and be continuing, the Agent may select such Liquid Investments. “Liquid Investments” means (i) direct obligations of the United States or any agency thereof, (ii) obligations guaranteed by the United States or any agency thereof, (iii) time deposits and money market deposit accounts issued by or guaranteed by or placed with a financial institution reasonably acceptable to the Agent, and (iv) fully collateralized repurchase agreements for securities described in clause (i) or (ii) above entered into with a financial institution reasonably acceptable to the Agent, provided in each case that such Liquid Investment (x) matures within 30 days and (y) is in a form, and is issued and held in a manner, that in the reasonable judgment of the Agent permits appropriate measures to have been taken to perfect security interests therein.

The effectiveness of this Agreement is subject to the satisfaction (or substantially simultaneous satisfaction) of the following conditions precedent:

(a) The Agent shall have received all fees and expenses (including, but not limited to, reasonable fees and expenses of counsel to the Agent) required to be paid on the Closing Date, pursuant to the terms of this Agreement and the Citicorp Fee Letter and the Annex thereto.

(i) a completed monthly Seller Report, signed by a Principal Financial Officer of the Servicer and dated within 31 days prior to the date of such Investment Event, together with a listing by Obligor of all Pool Receivables, and

(ii) during the existence of a Triggering Event, not later than the second Business Day of each week, a completed weekly Seller Report, signed by a Principal Financial Officer of the Servicer and effective as of the end of the last Business Day of the then immediately preceding week, and

(b) on the date of such Investment Event the following statements shall be true (and the acceptance by the Seller of the proceeds of the Purchase or reinvestment, as applicable, being made on the date of such Investment Event shall constitute a representation and warranty by the Servicer, or the Seller, as the case may be, that on the date of such Investment Event, such statements are true):

(i) the representations and warranties applicable to such Transaction Party contained in Article IV of this Agreement and in Article III of the Receivables Sale Agreement are correct in all material respects on and as of the date of such Investment Event, before and after giving effect to such Investment Event and to the application of the proceeds from the Purchase or reinvestment, as applicable, being made on the date thereof, as though made on and as of such date, except (x) in the case of an Investment Event consisting solely of a conversion of the Applicable Yield from a rate based on the Adjusted LIBO Rate to a rate based on the Adjusted Base Rate or (y) to the extent such representations and warranties that expressly relate to an earlier date;

(ii) no event has occurred and is continuing, or would result from such Investment Event or from the application of the proceeds from the Purchase or reinvestment, as applicable, being made on the date of such Investment Event, which constitutes an Event of Termination or a Potential Event of Termination; and

(iii) the Purchase or reinvestment, as applicable, being made on the same date as such Investment Event shall not violate any requirement of law and shall not be enjoined, temporarily, preliminarily or permanently.

(a) (i) The Seller is a limited liability company duly organized, validly existing and in good standing under the laws of the jurisdiction indicated at the beginning of this Agreement, has the requisite power and authority under its Constituent Documents and applicable law to own its property and assets and to carry on its business as now conducted and proposed to be conducted after the Closing Date and is duly qualified to do business, and is in good standing, in every jurisdiction where such qualification or authorization is required, except to the extent that any failure to be so qualified or in good standing as a foreign entity could not reasonably be expected to have a Material Adverse Effect.

(ii) The Seller has no Subsidiaries. All of the outstanding membership interests of the Seller are owned by Lyondell.

(b) The Seller has the power and authority under its Constituent Documents and applicable law to execute, deliver and carry out the provisions of the Transaction Documents to which it is a party, and all such actions have been duly and validly authorized by all necessary proceedings on its part under its Constituent Documents and applicable law.

(c) The execution, delivery and performance by the Seller of the Transaction Documents to which it is a party, and the transactions contemplated hereby and thereby, including the Seller’s use of the proceeds of Purchases and reinvestments, are within the Seller’s powers, have been duly authorized and delivered by all necessary action on its part, do not (i) violate (x) any provision of the Seller’s Constituent Documents or any other agreement governing its organization and/or scope of power and authority or any applicable law, rule, regulation (including Regulation U or X) or order, writ, judgment, injunction, decree, determination or award of any Governmental Authority binding upon it or any other Transaction Party, (ii) result in a breach of or constitute (alone or with notice or lapse of time or

both) a default under any indenture or any agreement or other instrument to which it is a party, or by which it or any of its properties or assets are bound, or (iii) except for the Liens created by the Transaction Documents, result in or require the creation or imposition of any Lien upon any of its property or assets.

(d) This Agreement is, and the other Transaction Documents to which the Seller is or will be a party when delivered will be, the legal, valid and binding obligations of the Seller enforceable against the Seller in accordance with their respective terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the rights of creditors generally and by general principles of equity, including implied obligations of good faith and fair dealing.

(e) No authorization or approval or other action by, and no notice to or filing with, any Governmental Authority is or will be required for the due execution, delivery and performance by the Seller of any Transaction Document to which it is a party or any transaction contemplated hereby or thereby, except for the filings of the financing statements referred to in Article III.

(f) Since the date of the Seller’s formation, there has not occurred any development or event affecting, or any change in the business, assets, results of operations, financial condition or prospects of, the Seller which has resulted or could reasonably be expected to result in a Material Adverse Effect.

(h) Maintenance of Seller’s Separate Existence. Take any action, or omit to take any action, if the effect is to cause the Seller to fail to perform or observe in any material respect the covenants contained in Section 5.1(d) and Section 5.1(j) above or to otherwise cause the Seller not to be considered as legal entity separate and distinct from Lyondell or any other Affiliates or Subsidiaries.

(a) The Pool Receivables shall be serviced, administered and collected by the Person (the “Servicer”) designated to do so from time to time in accordance with this Section 6.1.

(iv) The Seller and the Servicer each shall, at the Agent’s request, (A) assemble, and make available to the Agent at a place reasonably selected by the Agent or

its designee, all of the Records which evidence or relate to the Pool Receivables, and the related Contracts and Related Security, or which are otherwise necessary or desirable to collect the Pool Receivables, provided that, in the case of Records consisting of computer programs, data processing software and any other intellectual property under license from third parties, the Servicer will make available such Records only to the extent that the license for such property so permits, and provided, further, that during the continuance of a Potential Event of Termination, the Seller and the Servicer each shall, at the Agent’s request, commence the process of assembling such Records, and (B) segregate all cash, checks and other instruments received by it from time to time constituting Collections or other proceeds of Pool Receivables in a manner reasonably acceptable to the Agent and shall, promptly upon receipt, remit all such cash, checks and instruments, duly endorsed or with duly executed instruments of transfer, to the Agent or its designee.

(v) The Agent may take any and all commercially reasonable steps in the Seller’s or the Servicer’s name and on behalf of the Seller and the Purchasers necessary or desirable, in the determination of the Agent, to collect all amounts due under any and all Pool Receivables, including, without limitation, endorsing the Seller’s, or the Servicer’s name on checks and other instruments representing Collections or other proceeds of Pool Receivables, enforcing such Pool Receivables and the related Contracts, and adjusting, settling or compromising the amount or payment thereof, in the same manner and to the same extent as the Seller or the Servicer might have done.

(c) At any time during the continuance of a Triggering Event, the Agent may, upon the instructions of the Required Purchasers and at the Seller’s expense, request any of the Obligors of Pool Receivables to confirm the Outstanding Balance of such Obligor’s Pool Receivables.

(a) The Seller and the Servicer each shall perform all of its obligations under the Contracts related to the Pool Receivables to the same extent as if Receivable Interests had not been sold hereunder and the exercise by the Agent of its rights hereunder shall not release the Seller or the Servicer from such obligations or its obligations with respect to Pool Receivables or under the related Contracts; and

(b) Neither the Agent nor the Purchasers shall have any obligation or liability with respect to any Pool Receivables or related Contracts, nor shall any of them be obligated to perform any of the obligations of the Seller or any Originator thereunder.

(a) The Seller and the Servicer each 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 may be necessary, or that the Agent may reasonably request, in order to perfect, protect or more fully evidence or maintain the validity and effectiveness of the Receivable Interests purchased by the Purchasers hereunder, to carry out more effectively the purposes of the Transaction Documents and to enable any of them or the Agent to exercise and enforce any of their respective rights and remedies under the Transaction Documents. Without limiting the generality of the foregoing, the Seller and the Servicer each will upon the request of the Agent, in order to perfect, protect or evidence such Receivable Interests: (i) file or cause to be filed such financing or continuation statements, or amendments thereto or

assignments thereof, and such other instruments or notices, as may be necessary, or as the Agent may reasonably request; (ii) from and after April 1, 2004, mark conspicuously each invoice evidencing each Pool Receivable with a legend stating that such Pool Receivable and related Contract has been sold, transferred and assigned to the Seller; and (iii) mark its master data processing records evidencing such Pool Receivables and related Contracts with such legend. The Servicer also agrees to provide to the Agent, from time to time upon request, evidence reasonably satisfactory to the Agent as to the perfection and priority of the Liens created or intended to be created by the Transaction Documents.

(b) The Seller hereby authorizes the Agent to file one or more financing or continuation statements, and amendments thereto and assignments thereof, relating to all or any of the Contracts, or Pool Receivables and the Related Security and Collections with respect thereto, now existing or hereafter arising, without the signature of the Seller where permitted by law. A photocopy or other reproduction of this Agreement or any financing statement covering all or any of the Contracts, or Pool Receivables and the Related Security and Collections with respect thereto shall be sufficient as a financing statement where permitted by law.

(c) If the Servicer or the Seller fails to perform any agreement contained herein, then after notice to the Servicer or the Seller, as applicable, the Agent may itself perform, or cause performance of, such agreement, and the reasonable costs and expenses of the Agent incurred in connection therewith shall be payable by the Seller under Section 10.1 or Section 11.5, as applicable.

If any of the following events (“Events of Termination”) shall occur and be continuing:

(a) The Seller or the Servicer shall fail to make any payment or deposit to be made by it hereunder when due and, except for deposits in respect of Capital, such failure shall continue for a period of at least five consecutive days; or

specific Pool Receivable and gives rise to an obligation of the Seller to make a payment under Section 2.9(c) in respect of the affected Pool Receivable and the Seller has made such payment in accordance with Section 2.9(c) and, after giving effect to such payment and, if applicable, any calculated reduction in Capital by an amount on deposit in the Cash Assets Account that is available for application therefor pursuant to Section 2.6 or 2.7, as applicable, the aggregate Receivable Interests would not exceed 100%; (ii) any Originator shall fail to perform or observe any term, covenant or agreement contained in Section 4.01(g), 4.01(i), 4.02(f) or 4.03 of the Receivables Sale Agreement; (iii) Lyondell shall fail to perform or observe any term, covenant or agreement contained in Sections 3.07 through 3.18 of the Lyondell Undertaking; (iv) (x) the Servicer shall fail to observe or perform any term, covenant or agreement contained in any of Sections 5.5(a) through 5.5(e) or Section 5.5(h) or 5.5(i) of this Agreement, (y) any Originator shall fail to observe or perform any term, covenant or agreement contained in Section 4.02 (excluding Section 4.02(f)) of the Receivables Sale Agreement, or (z) Lyondell shall fail to perform or observe any term, covenant or agreement contained in Section 3.01 or 3.03 of the Lyondell Undertaking, and, in such case, such failure shall continue for a period of five days; or (v) any Transaction Party shall fail to perform or observe any other term, covenant or agreement contained in any Transaction Document on its part to be performed or observed and any such failure shall remain unremedied for 30 days after the earlier of (A) the date on which a Responsible Officer of any Transaction Party becomes aware of such failure and (B) the date on which written notice thereof shall have been given to the Seller by the Agent or any Purchaser; or

(ii) any event or condition shall occur which results in the acceleration of the maturity of any Material Debt or enables (or, with the giving of notice or lapse of time or both, would enable) the holder of such Indebtedness or any Person acting on such holder’s behalf to accelerate the maturity thereof; provided that (a) an event or condition which does not presently enable such holder or other Person to accelerate the maturity of such Indebtedness and which is subsequently waived or cured will then no longer constitute an Event of Termination hereunder; (b) the existence or exercise of rights of holders of Indebtedness under the Medium Term Notes to require repurchase thereof arising from the admission of Subsidiaries of Occidental to Equistar shall not give rise to an Event of Termination or Potential Event of Termination under this subsection; and (c) no Event of Termination shall arise under this Section 7.1(d) in respect of Indebtedness which is Guaranteed by, but is not otherwise Indebtedness of, Lyondell or any Material Subsidiary (including for this purpose the Lyondell Joint Ventures); or

(iii) an “Event of Default” shall exist under (and as defined in) the Credit Agreement; or, if the Intercreditor Agreement is then in effect, a notice to terminate the sale of Receivables under the Transaction Documents shall have been delivered under the Intercreditor Agreement; or

(e) Any Purchase shall for any reason (other than pursuant to the terms hereof) cease to create, or any Receivable Interest shall for any reason cease to be, a valid and perfected first priority undivided percentage ownership interest or security interest to the extent of the pertinent Receivable Interest in each applicable Pool Receivable and the Related Security and Collections with respect thereto, except by reason of action taken voluntarily by the Agent, or the failure by the Agent to take action required to be taken by it under the Transaction Documents; provided, however, that any such event that relates to a specific Pool Receivable shall not constitute an Event of Termination under this Section 7.1(e) if the occurrence of such event gives rise to an obligation of the Seller to make a payment under Section 2.9(c)

in respect of the affected Pool Receivable and the Seller has made such payment in accordance with Section 2.9(c) and, after giving effect to such payment and, if applicable, any calculated reduction in Capital by an amount held in the Cash Assets Account that is available for application therefor pursuant to Section 2.6 or 2.7, as applicable, the aggregate Receivable Interests would not exceed 100%; or

(f) (i) any Transaction Party or any Material Subsidiary (x) shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to itself or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors; or (y) shall fail generally to pay its debts as they become due; or (z) shall take any corporate action to authorize any of the foregoing; or (ii) an involuntary case or other proceeding shall be commenced against any Transaction Party or any Material Subsidiary seeking liquidation, reorganization or other relief with respect to it or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 60 days; or (iii) an order for relief shall be entered against any Transaction Party or any Material Subsidiary under the federal bankruptcy laws as now or hereafter in effect (for purposes of this Section 7.1(f), a Material Subsidiary includes the Lyondell Joint Ventures, but excludes LCR so long as LCR is not at the time a “Significant Subsidiary” for purposes of the instruments governing the Senior Notes or the Senior Subordinated Notes); or

(g) Any member of the ERISA Group shall fail to pay when due an amount or amounts which it shall have become liable to pay under Title IV of ERISA; or notice of intent to terminate a Plan shall be filed under Title IV of ERISA by any member of the ERISA Group, any plan administrator or any combination of the foregoing; or the PBGC shall institute proceedings under Title IV of ERISA to terminate, to impose liability (other than for premiums under Section 4007 of ERISA) in respect of, or to cause a trustee to be appointed to administer, any Plan; or a condition shall exist by reason of which the PBGC would be entitled to obtain a decree adjudicating that any Plan must be terminated; or there shall occur a complete or partial withdrawal from, or a default, within the meaning of Section 4219(c)(5) of ERISA, with respect to, one or more Multiemployer Plans which could cause one or more members of the ERISA Group to incur a current payment obligation, if any of the foregoing could reasonably be expected to have a Material Adverse Effect (it being understood that the fact that Lyondell is a party to the PBGC Settlement Agreement is not, in itself, expected to have a Material Adverse Effect); or

(h) The Net Receivables Pool Balance shall be less than the Required Net Receivables Pool Balance (giving effect to any calculated reduction in Capital by an amount equal to the amount on deposit in the Cash Assets Account that is available for application therefor pursuant to Section 2.6 or 2.7, as applicable, as of the close of business on the relevant day of determination) for a period of 2 consecutive Business Days or more; or

(i) Any Transaction Document shall for any reason cease to be in full force and effect, or any Transaction Party shall so state in writing; or

(k) (i) one or more judgments or orders for the payment of money shall be rendered by a court or other tribunal or governmental agency against the Seller or (ii) judgments or orders for the payment of money exceeding $50,000,000 in aggregate amount (exclusive of amounts covered by

insurance as to which the carrier has not contested coverage) shall be rendered against a Transaction Party (other than the Seller) or any Subsidiary (including for this purpose the Lyondell Joint Ventures) and such judgments or orders shall continue undischarged, unsatisfied and unstayed for a period of 30 days; or enforcement remedies in respect of any such judgments or orders shall be commenced; or

(l) (i) Receivables Excess Availability shall for a period of two consecutive Business Days be less than (x) $25,000,000 from the Closing Date through June 30, 2005 or (y) $15,000,000 thereafter; or (ii) Total Excess Availability shall for a period of two consecutive Business Days be less than $50,000,000;

then, and in any such event, the Agent shall, at the request, or may with the consent, of the Required Purchasers, by notice to the Seller and the Servicer declare the Termination Date to have occurred, whereupon the Termination Date shall forthwith occur; provided, that, (x) if the Intercreditor Agreement is then in effect, automatically upon the second Business Day following the effectiveness of any notice to terminate the sale of Receivables under the Transaction Documents delivered in accordance with the Intercreditor Agreement, the Termination Date shall occur and (y) automatically upon the occurrence of any event (without any requirement for the passage of time or the giving of notice, or both) described in subsection (f) of this Section 7.1, the Termination Date shall occur, and the Agent may replace the Servicer pursuant to Section 6.1. Upon any such occurrence of the Termination Date, the Agent and each Purchaser shall have, in addition to all other rights and remedies under this Agreement or otherwise, all other rights and remedies provided under any and all applicable laws, which rights shall be cumulative.

(a) Each Purchaser hereby appoints CUSA as the Agent hereunder and each Purchaser authorizes the Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Transaction Documents as are delegated to the Agent under such agreements and to exercise such powers as are reasonably incidental thereto. Without limiting the foregoing, each Purchaser hereby authorizes the Agent to execute and deliver, and to perform its obligations under, each of the Transaction Documents to which the Agent is a party, to exercise all rights, powers and remedies that the Agent may have under such Transaction Documents.

(b) As to any matters not expressly provided for by this Agreement and the other Transaction Documents (including enforcement or collection), the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Purchasers, and such instructions shall be binding upon all Purchasers; provided, however, that the Agent shall not be required to take any action that (i) the Agent in good faith believes exposes it to personal liability unless the Agent receives an indemnification satisfactory to it from the Purchasers with respect to such action or (ii) is contrary to this Agreement or applicable law. The Agent agrees to give to each Purchaser prompt notice of each notice given to it by the Seller, Originator or Servicer pursuant to the terms of this Agreement or the other Transaction Documents.

(c) In performing its functions and duties hereunder and under the other Transaction Documents, the Agent is acting solely on behalf of the Purchasers and its duties are entirely administrative in nature. The Agent does not assume and shall not be deemed to have assumed any obligation other than as expressly set forth herein and in the other Transaction Documents or any other

relationship as the agent, fiduciary or trustee of or for any Purchaser or holder of any other obligation under any Transaction Document. The Agent may perform any of its duties under any Transaction Document by or through its agents or employees.

Neither the Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them as Agent under or in connection with this Agreement or any other Transaction Document or any other instrument or document delivered pursuant hereto (including, without limitation, the Agent’s servicing, administering or collecting Pool Receivables as Servicer pursuant to Section 6.1), except for its or their own gross negligence or willful misconduct. Without limiting the generality of the foregoing, except as otherwise agreed by the Agent and any Purchaser, the Agent: (i) may consult with legal counsel (including counsel for the Seller, the Servicer or any Originator), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (ii) makes no warranty or representation to any Purchaser and shall not be responsible to any Purchaser for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement or any other Transaction Document or any other instrument or document delivered pursuant hereto; (iii) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or any other Transaction Document or any other instrument or document delivered pursuant hereto on the part of the Seller or any Originator or to inspect the property (including the books and records) of the Seller or any Originator; (iv) shall not be responsible to any Purchaser for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other Transaction Document or any other instrument or document furnished pursuant hereto, or the perfection, priority or value of any ownership interest or security interest created or purported to be created hereunder or under the Receivables Sale Agreement; and (v) shall incur no liability under or in respect of this Agreement or any other Transaction Document or any other instrument or document delivered pursuant hereto by acting upon any notice (including notice by telephone), consent, certificate or other instrument or writing (which may be by telecopier, telegram, cable or telex) reasonably believed by it to be genuine and signed or sent by the proper party or parties.

With respect to any Capital or any Receivable Interest owned by it, CUSA shall have the same rights and powers under this Agreement as any other Purchaser and may exercise the same as though it were not the Agent. CUSA and its Affiliates may generally engage in any kind of business with the Seller or any Originator or any Obligor, any of their respective Affiliates and any Person who may do business with or own securities of the Seller or any Originator or any Obligor or any of their respective Affiliates, all as if CUSA were not the Agent and without any duty to account therefor to the Purchasers.

Each Purchaser acknowledges that it has, independently and without reliance upon the Agent or any of its Affiliates or any other Purchaser and based on such documents and information as it has deemed appropriate, made its own evaluation and decision to enter into this Agreement and to purchase undivided ownership interests in Pool Receivables hereunder. Each Purchaser also acknowledges that it shall, independently and without reliance upon the Agent, any of its Affiliates or any other Purchaser and based on such documents and information as it shall deem appropriate at the time, continue to make its own decisions in taking or not taking action under this Agreement.

The Purchasers agree to indemnify the Agent (to the extent not promptly reimbursed by the Seller or the Servicer), ratably according to their Ratable Portion from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of this Agreement or any other Transaction Document or any other instrument or document furnished pursuant hereto or any action taken or omitted by the Agent under this Agreement or any other Transaction Document or any such instrument or document; provided that no Purchaser shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, the Purchasers agree to reimburse the Agent, ratably according to their Ratable Portion, promptly upon demand for any costs and expenses (including, without limitation, reasonable fees and disbursements of counsel) payable by the Seller to the Agent under Section 11.5, to the extent that the Agent is not promptly reimbursed for such costs and expenses by the Seller.

The Agent may resign at any time by giving written notice thereof to the Purchasers and the Seller. Upon any such resignation, the Required Purchasers shall have the right to appoint a successor Agent. If no successor Agent shall have been so appointed by the Required Purchasers, and shall have accepted such appointment, within 30 days after the retiring Agent’s giving of notice of resignation, then the retiring Agent may, on behalf of the Purchasers, appoint a successor Agent, selected from among the Purchasers. In either case, such appointment shall be subject to the prior written approval of the Seller (which approval may not be unreasonably withheld and shall not be required upon the occurrence and during the continuance of an Event of Termination). Upon the acceptance of any appointment as Agent by a successor Agent, such successor Agent shall succeed to, and become vested with, all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under this Agreement and the other Transaction Documents. Prior to any retiring Agent’s resignation hereunder as Agent, the retiring Agent shall take such action as may be reasonably necessary to assign to the successor Agent its rights as Agent under the Transaction Documents. After such resignation, the retiring Agent shall continue to have the benefit of this Article VIII as to any actions taken or omitted to be taken by it while it was Agent under this Agreement and the other Transaction Documents.

(a) Subject to certain limited exceptions in respect of which the Servicer or the Seller has delivered prior written notice to the Agent, each of the Purchasers, the Servicer and the Seller agree that the Agent may, but shall not be obligated to, make the Approved Electronic Communications available to the Purchasers by posting such Approved Electronic Communications on “e-Disclosure”, the Agent’s internet delivery system that is part of Fixed Income Direct, Global Fixed Income’s primary web portal, or successor electronic platform chosen by the Agent to be its internet delivery system (the “Approved Electronic Platform”).

(b) Although the primary web portal is secured with a dual firewall and a user ID/password authorization system and the Approved Electronic Platform is secured through a single-user-per-deal authorization method whereby each user may access the Approved Electronic Platform only on a deal-by-deal basis, each of the Purchasers, the Servicer and the Seller acknowledges and agrees that the distribution of material through an electronic medium is not necessarily secure and that there are

confidentiality and other risks associated with such distribution. In consideration for the convenience and other benefits afforded by such distribution and for the other consideration provided hereunder, the receipt and sufficiency of which is hereby acknowledged, each of the Purchasers, the Servicer and the Seller hereby approves, and the Servicer shall cause each Originator to approve, distribution of the Approved Electronic Communications through the Approved Electronic Platform and understands and assumes the risks of such distribution.

(c) The Approved Electronic Communications and the Approved Electronic Platform are provided “as is” and “as available”. None of the Agent or any of its Affiliates or any of their respective officers, directors, employees, agents, advisors or representatives (the “Agent Affiliates”) warrants the accuracy, adequacy or completeness of the Approved Electronic Communications and the Approved Electronic Platform and each expressly disclaims liability for errors or omissions not committed by it or in the absence of its gross negligence or willful misconduct in the Approved Electronic Communications and the Approved Electronic Platform. No warranty of any kind, express, implied or statutory (including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third party rights or freedom from viruses or other code defects) is made by the Agent Affiliates in connection with the Approved Electronic Platform.

(a) Each Purchaser may assign to any Eligible Assignee all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment and the Receivable Interests owned by it); provided, however, that (i) each such assignment shall be a constant, and not a varying, percentage of such Purchaser’s rights and obligations under this Agreement and the Receivable Interests owned by it, (ii) in the case of any assignment by any Purchaser that is not assigning pursuant thereto all of its right and obligations under this Agreement, (A) the amount of the Commitment (determined as of the date of the applicable Assignment and Acceptance) being assigned pursuant to each such assignment shall be at least $5,000,000, or (B) the aggregate amount of all Commitments (determined as of the date of the applicable Assignments and Acceptances) being assigned by such Purchaser on such date to two or more Eligible Assignees that are Affiliates of each other shall be at least $5,000,000, (iii) each such assignment shall be to an Eligible Assignee, (iv) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with a processing and recording fee of $3,500, and (v) the consent of the Agent and, unless an Event of Termination has occurred and is continuing, the Seller shall first have been obtained. Upon such execution, delivery and acceptance, from and after the effective date specified in each Assignment and Acceptance, which effective date shall be the later of (x) the date the Agent receives the executed Assignment and Acceptance and (y) the date of such Assignment and Acceptance, (1) the Assignee thereunder shall be a party hereto and shall have all the rights and obligations of a Purchaser hereunder and (2) the assigning Purchaser shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such assignment and acceptance, relinquish its rights and be released from its obligations under this Agreement.

(b) By executing and delivering an Assignment and Acceptance, the assigning Purchaser and the Assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, the assigning Purchaser makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or any other Transaction Document or any

other instrument or document furnished pursuant hereto or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other Transaction Document or any other instrument or document furnished pursuant hereto, or the perfection, priority or value of any ownership interest or security interest created or purported to be created hereunder or under the Receivables Sale Agreement; (ii) the assigning Purchaser makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Seller, the Servicer or any Originator or the performance or observance by the Seller, the Servicer or any Originator of any of their respective obligations under this Agreement or any other Transaction Document or any other instrument or document furnished pursuant hereto; (iii) such Assignee confirms that it has received copies of this Agreement and the other Transaction Documents, together with such other documents and information as it has deemed appropriate to make its own analysis and decision to enter into such Assignment and Acceptance; (iv) such Assignee will, independently and without reliance upon the Agent, any of its Affiliates, the assigning Purchaser or any other Purchaser and based on such documents and information as it shall deem appropriate at the time, continue to make its own decisions in taking or not taking action under this Agreement and the other Transaction Documents and the other instruments and documents furnished pursuant hereto; (v) such Assignee confirms that it is an Eligible Assignee; (vi) such Assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement and the other Transaction Documents and the other instruments and documents furnished pursuant hereto as are delegated to the Agent by the terms hereof and thereof, together with such powers and discretion as are reasonably incidental thereto; (vii) such Assignee appoints as its agent the Servicer from time to time designated pursuant to Section 6.1 to enforce its respective rights and interests in and under the Pool Receivables and the Related Security and Collections with respect thereto and the related Contracts; and (viii) such Assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Purchaser.

(c) Upon its receipt of an Assignment and Acceptance executed by any assigning Purchaser and an assignee representing that it is an Eligible Assignee, the Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit A hereto, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register, and (iii) give prompt notice thereof to the Seller and the Servicer.

(d) Any Purchaser may, in connection with any assignment or proposed assignment pursuant to Section 9.1, disclose to the assignee or proposed assignee any information relating to any Transaction Party or any Affiliate or Subsidiary furnished to the Purchasers by or on behalf of such Transaction Party or such Affiliate or Subsidiary, as applicable; provided that, prior to any such disclosure, each such assignee or proposed assignee shall execute an agreement whereby such assignee or proposed assignee shall agree (subject to customary exceptions) to preserve the confidentiality of any confidential information relating to the Transaction Parties and any Affiliate or Subsidiary received from the Agent or the Purchasers.

(e) Notwithstanding anything to the contrary contained herein, any Purchaser (a “Granting Purchaser”) may grant to a special purpose funding vehicle (an “SPC”) of such Granting Purchaser, identified as such in writing from time to time by the Granting Purchaser to the Agent and the Seller, the option to provide to the Seller all or any part of any Purchase that such Granting Purchaser would otherwise be obligated to make to the Seller pursuant to Section 2.2, provided that (i) nothing herein shall constitute a commitment to make any Purchase by any SPC and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Purchase, the Granting Purchaser shall be obligated to make such Purchase pursuant to the terms hereof. The making of a Purchase by an SPC hereunder shall be deemed to utilize the Commitments of all the Purchasers to the same extent, and as if, such Purchase were made by the Granting Purchaser. Each party hereto hereby agrees that no SPC

shall be liable for any payment under this Agreement for which a Purchaser would otherwise be liable, for so long as, and to the extent, the related Granting Purchaser makes such payment. In furtherance of the foregoing, each party hereto hereby agrees that, prior to the date that is one year and one day after the payment in full of all outstanding senior indebtedness of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings or similar proceedings under the laws of the United States of America or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 9.1, any SPC may assign all or a portion of its interests in any Receivable Interests to its Granting Purchaser or to any financial institutions providing liquidity and/or credit facilities to or for the account of such SPC to fund the Purchases made by such SPC or to support the securities (if any) issued by such SPC to fund such Purchases; provided, however, that except in the case of an assignment to a Granting Purchaser or a financial institution that is either an Affiliate of such SPC or another Purchaser, the Agent and, unless an Event of Termination has occurred and is continuing, the Seller must consent to such assignment in writing (which consent may not be unreasonably withheld). Each SPC shall execute an agreement whereby such SPC shall agree (subject to customary exceptions) to preserve the confidentiality of any confidential information relating to the Transaction Parties and its Affiliates or Subsidiaries received from the Agent or Purchasers.

The Agent shall maintain at its office referred to in Section 11.3 a copy of each Assignment and Acceptance delivered to and accepted by it and a register (the “Register”) for the recordation of the names and addresses of the Purchasers and the Commitment of, and each Receivable Interest owned by, each Purchaser from time to time, which Register shall be available for inspection by the Seller at any reasonable time upon reasonable prior notice. The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the parties hereto may treat each Person whose name is recorded in the Register as a Purchaser hereunder for all purposes of this Agreement. No Receivable Interest, nor any Assignment and Acceptance, shall be effective unless it is entered in the Register in due course.

With the prior written consent of the Agent, each Purchaser may sell participations to one or more Persons in or to all or a portion of its rights and obligations under the Transaction Documents (including all its rights and obligations with respect to Receivable Interests). The terms of such participation shall not, in any event, require the participant’s consent to any amendments, waivers or other modifications of any provision of any Transaction Documents, the consent to any departure by any Transaction Party therefrom, or to the exercising or refraining from exercising any powers or rights such Purchaser may have under or in respect of the Transaction Documents (including the right to enforce the obligations of any Transaction Party), except if any such amendment, waiver or other modification or consent would reduce the amount, or postpone any date fixed for, any amount (whether of Capital, Yield or fees) payable to such participant under the Transaction Documents, to which such participant would otherwise be entitled under such participation. In the event of the sale of any participation by any Purchaser, (w) such Purchaser’s obligations under the Transaction Documents shall remain unchanged, (x) such Purchaser shall remain solely responsible to the other parties for the performance of such obligations, (y) such Purchaser shall remain the holder of such Capital for all purposes of this Agreement and (z) the Seller, the Agent and the other Purchasers shall continue to deal solely and directly with such Purchaser in connection with such Purchaser’s rights and obligations under this Agreement. Each participant shall be entitled to the benefits of Sections 2.12(a), 2.13 and 2.14 as if it were a Purchaser; provided, however, that anything herein to the contrary notwithstanding, the Seller shall not, at any time, be obligated to make under Section 2.12(a), 2.13 or 2.14 to the participants in the rights and obligations of

any Purchaser (together with such Purchaser) any payment in excess of the amount the Seller would have been obligated to pay to such Purchaser in respect of such interest had such participation not been sold. Any Purchaser may, in connection with any participation or proposed participation pursuant to Section 9.3, disclose to the participant or proposed participant any information relating to any Transaction Party or any Affiliate or Subsidiary of Lyondell furnished to the Purchasers by or on behalf of such Transaction Party or such Affiliate or Subsidiary, as applicable; provided that, prior to any such disclosure, each such participant or proposed participant shall execute an agreement whereby such participant or proposed participant shall agree (subject to customary exceptions) to preserve the confidentiality of any confidential information relating to the Transaction Parties and any Affiliate or Subsidiary of Lyondell received from the Agent or the Purchasers.

Without limiting any other rights that any Indemnified Party may have hereunder or under applicable law, and whether or not any of the transactions contemplated hereby are consummated, (A) the Seller hereby agrees to indemnify each Indemnified Party from and against, and hold each thereof harmless from, any and all claims, losses, liabilities, costs and expenses of any kind whatsoever (including, without limitation, reasonable attorneys’ fees and expenses) (all of the foregoing being collectively referred to as “Indemnified Amounts”) arising out of, or resulting from, in whole or in part, one or more of the following: (a) this Agreement or any other Transaction Document (other than the Lyondell Undertaking or the Servicer’s activities as Servicer) to which it is a party; (b) the use of proceeds of any Purchase or reinvestment; (c) the interest of any Purchaser in any Receivable, any Contract or any Related Security; or (d) any transaction contemplated by this Agreement or any other Transaction Document (other than the Lyondell Undertaking) to which it is a party; and (B) the Servicer hereby agrees to indemnify each Indemnified Party for Indemnified Amounts arising out of or resulting from the Lyondell Undertaking or the Servicer’s activities as Servicer or Buyer’s Servicer hereunder or under the other Transaction Documents; excluding, however, in all of the foregoing instances under clauses (A) and (B) above, Indemnified Amounts (1) to the extent resulting from (x) the gross negligence or willful misconduct on the part of such Indemnified Party or, (y) the failure to collect amounts in respect of a Pool Receivable, to the extent such failure results from a discharge of the Obligor with respect thereto in a proceeding in respect of such Obligor under applicable bankruptcy laws or otherwise results from the Obligor’s financial inability to pay such amounts or (2) that are subject to the exclusions from reimbursement or payment therefor under Section 2.14. Without limiting or being limited by the foregoing and whether or not any of the transactions contemplated hereby are consummated, the applicable Seller Party shall pay within five Business Days after demand to each Indemnified Party any and all amounts necessary to indemnify such Indemnified Party from and against any and all Indemnified Amounts which relate to or result from, or which would not have occurred but for, one or more of the following:

(i) any Receivable becoming a Pool Receivable which is stated to be, but is not, an Eligible Receivable;

(iv) the failure to vest in the Purchaser of a Receivable Interest a first priority perfected undivided percentage ownership interest, to the extent of such Receivable Interest, in each Receivable in, or purported to be in, the Receivables Pool and the Related Security and Collections in respect thereof, free and clear of any Lien (except for Liens created pursuant to the Transaction Documents); or the failure of the Seller to have obtained a first priority perfected ownership interest in the Pool Receivables and the Related Security and Collections with respect thereto transferred or purported to be transferred to the Seller under the Receivables Sale Agreement, free and clear of any Lien (except for Liens created pursuant to the Transaction Documents);

(v) the failure of such Seller Party to have filed, or any delay by such Seller Party in filing, financing statements or other similar instruments or documents under the UCC of any applicable jurisdiction or other applicable laws with respect to any Receivable in, or purported to be in, the Receivables Pool and the Related Security and Collections in respect thereof, whether at the time of any Purchase or reinvestment or at any subsequent time unless such failure results directly and solely from the Agent’s failure to take appropriate action;

(vi) any dispute, claim, offset or defense (other than discharge in bankruptcy of the Obligor) of any Obligor to the payment of any Receivable in, or purported to be in, the Receivables Pool (including, without limitation, any defense based on the fact or allegation that such Receivable or the related Contract is not 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;

(vii) any failure of such Seller Party to perform its duties or obligations in accordance with the provisions of this Agreement or any other Transaction Document or to perform its duties or obligations under any Contract;

(viii) any product liability, personal injury, copyright infringement, theft of services, property damage, or other breach of contract, antitrust, unfair trade practices or tortious claim arising out of or in connection with the subject matter of any Contract or out of or in connection with any transaction contemplated by this Agreement, any other Transaction Document or any other instrument or document furnished pursuant hereto or such Contract;

(ix) the commingling by such Seller Party of Collections of Pool Receivables at any time with other funds;

(xi) any cancellation or modification of a Pool Receivable, the related Contract or any Related Security, whether by written agreement, verbal agreement, acquiescence or otherwise, unless such cancellation or modification was made by or with the express consent of the Agent or a Servicer that is not Lyondell or an Affiliate or Subsidiary of Lyondell; provided that in no event shall Indemnified Amounts include any unpaid portion of a Pool Receivable effected by any such cancellation or modification;

(xii) any investigation, litigation or proceeding related to or arising from this Agreement, any other Transaction Document or any other instrument or document furnished pursuant hereto or thereto, or any transaction contemplated by this Agreement or any Contract or the use of proceeds from any Purchase or reinvestment pursuant to this Agreement, or the ownership of, or other interest in, any Receivable, the related Contract or Related Security;

(xv) any claim brought by any Person other than an Indemnified Party arising from any activity of such Seller Party in servicing, administering or collecting any Pool Receivable; or

(xvi) any failure by any Lock-Box Bank or other depository bank at which a Restricted Account is maintained to comply with the terms of the Transaction Document governing such Restricted Account to which it is a party.

No amendment or waiver of any provision of this Agreement or the Intercreditor Agreement, and no consent to any departure by the Seller or the Servicer therefrom, shall be effective unless in a writing signed by the Agent and the Required Purchasers and, in the case of any such amendment, the Seller and the Servicer and then such amendment, waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no amendment, waiver or consent shall:

(i) amend the definitions of “Eligible Receivable”, “Net Receivables Pool Balance”, “Required Net Receivables Pool Balance” or “Super Majority Purchasers”, “Required Purchasers”; or

(ii) amend, modify or waive any provision of this Agreement in any way which would

(A) reduce the amount of a Capital Investment or Yield that is payable on account of any Receivable Interest or delay any scheduled date for payment thereof or reduce the Applicable Margin or change the order of application of Collections to the payment thereof, or

(B) impair any rights expressly granted to such Purchaser under this Agreement, or

(C) reduce fees payable by the Seller to or for the account of such Purchaser hereunder or delay the dates on which such fees are payable, or

(iii) amend or waive the Event of Termination contained in Section 7.1(f) relating to the bankruptcy of any Transaction Party, or amend or waive the Event of Termination contained in Section 7.1(h) relating to the Net Receivables Pool Balance, or

(iv) change the percentage of Commitments, or the number of Purchasers or Purchasers, which shall be required for the Purchasers or any of them to take any action hereunder, or

(viii) reduce the Reserve Percentage, or amend the definition of “Reserve Percentage”, in each case such that the Reserve Percentage is reduced, below 15%;

(b) without the consent of the applicable Purchaser, increase the Commitment of such Purchaser, subject such Purchaser to any additional obligations, or decrease the Receivable Interest of such Purchaser; and

(c) without the consent of the Super Majority Purchasers, amend the definitions of “Receivables Excess Availability” or “Total Excess Availability” amend, or waive any Event of Termination or Potential Event of Termination arising under, Section 7.1(l) hereof;

provided, however, that the Agent shall not, without the prior written consent of the Required Purchasers, either agree to any amendment or waiver of any other provision of the Lyondell Undertaking or any provision of any Intercreditor Agreement or other Transaction Document or consent to any departure from the Lyondell Undertaking or the Intercreditor Agreement or other Transaction Document by any party thereto, and provided further, that (x) no amendment, waiver or consent shall, unless in writing and signed by the Agent in addition to the Purchasers required above to take such action, affect the rights or duties of the Agent under this Agreement or the other Transaction Documents, and (y) no amendment, waiver or consent shall, unless in writing and signed by the Swing Purchaser in addition to the Purchasers required above to take such action, affect the rights or duties of the Swing Purchaser under this Agreement or the other Transaction Documents.

If, in connection with any proposed amendment, modification, waiver or termination requiring the consent of all affected Purchasers, the consent of the Required Purchasers is obtained but the consent of other Purchasers whose consent is required is not obtained (any such Purchaser whose consent is not obtained being referred to as a “Non-Consenting Purchaser”), then, so long as the Purchaser that is the same entity as the Agent is not a Non-Consenting Purchaser, at the Seller’s request, the Agent or an Eligible Assignee acceptable to the Agent shall have the right with the Agent’s consent and in the Agent’s sole discretion (but shall have no obligation) to purchase from such Non-Consenting Purchaser, and such Non-Consenting Purchaser agrees that it shall, upon the Agent’s request, sell and assign to the Purchaser that is the same entity as the Agent or to such Eligible Assignee, all of the Commitment and Receivable Interest of such Non-Consenting Purchaser for an amount equal to the outstanding Capital represented by the Receivable Interest of the Non-Consenting Purchaser plus all accrued Yield and fees with respect thereto through the date of sale less unamortized upfront fees, such purchase and sale to be consummated pursuant to an executed Assignment and Acceptance.

No failure on the part of any Purchaser or the Agent 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.

Each Purchaser is hereby authorized by the Seller upon the occurrence and during the continuance of an Event of Termination, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other Indebtedness at any time owing by such Purchaser to or for the credit or the account of the Seller against any and all of the obligations of the Seller now or hereafter existing under this Agreement to such Purchaser or, if such Purchaser is CUSA, to the Agent or any Affiliate thereof, irrespective of whether or not any formal demand shall have been made under this Agreement and although such obligations may be unmatured. Each Purchaser agrees promptly to notify the Seller after any such setoff and application; provided, however, that the failure to give such notice shall not affect the validity of such setoff and application. The rights of each Purchaser under this Section 11.2 are in addition to other rights and remedies (including, without limitation, other rights of setoff) which such Purchaser may have.

All notices and other communications hereunder shall, unless otherwise stated herein, be given in writing or by any telecommunication device capable of creating a written record (including, with respect to Approved Electronic Communications and other notices and communications described below, electronic mail), (i) to each of the Seller, the Servicer, the Agent and the Initial Purchasers, at its address set forth under its name on the signature pages hereof, (ii) to each Purchaser other than the Initial Purchasers, at its address specified on the Assignment and Acceptance pursuant to which it became a Purchaser hereunder or (iii) to any party hereto at such other address as shall be designated by such party in a notice to the other parties hereto given as provided herein.

All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt if delivered by hand or overnight courier service or sent by telecopy equipment of the sender, or on the date five Business Days after dispatch by certified or registered mail if mailed, in each case delivered, sent or mailed (properly addressed) to such party as provided in this Section 11.3 or in accordance with the latest unrevoked direction from such party given in accordance with this Section 11.3.

Notices and other communications to the Purchasers hereunder not constituting Approved Electronic Communications may be delivered or furnished by electronic communications pursuant to procedures approved by the Agent; provided that the foregoing shall not apply to notices pursuant to Article II or III unless otherwise agreed by the Agent and the applicable Purchaser. Each of the Agent, the Seller and the Servicer may, in its discretion, agree to accept notices and other communications to it hereunder or under any other Transaction Document that do not constitute Approved Electronic Communications, by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications.

This Agreement shall be binding upon and inure to the benefit of each party hereto and their respective successors and assigns, except that neither the Seller, any Originator, nor the Servicer shall have the right to assign its rights or obligations hereunder or any interest herein without the prior written consent of all Purchasers. This Agreement shall create and constitute the continuing obligation of the parties hereto in accordance with its terms, and shall remain in full force and effect until such time, after the Termination Date, as no Capital or any other obligation of the Seller, any Originator, or the Servicer under any Transaction Document shall be outstanding; provided, however, that rights and remedies with respect to the provisions of Sections 2.12, 2.13, 2.14, 10.1, 11.5, 11.6, and 11.8 shall be continuing and shall survive any termination of this Agreement.

The Seller shall pay (i) all reasonable out-of-pocket expenses incurred by the Agent, including the reasonable fees, charges and disbursements of Davis Polk & Wardwell, special counsel for the Agent and any local counsel retained by them, in connection with the syndication of the receivables facilities provided for herein, the preparation and administration of the Transaction Documents or any amendments, modifications or waivers of the provisions thereof (whether or not the transactions contemplated hereby or thereby shall be consummated) and (ii) all out-of-pocket expenses incurred by the Agent or any Purchaser, including the fees, charges and disbursements of any counsel for the Agent or any Purchasers, in connection with the enforcement or protection of its rights in connection with any Transaction Document, including its rights under this Section, or in connection with the Receivable Interests, including all such out-of-pocket expenses incurred during any workout or restructuring in respect of such Receivable Interests. It is understood that reimbursement of the Agent in respect of matters covered by Section 5.1(f) or 5.4(f) of this Agreement is subject to the applicable limitations specified herein.

Each of the Agent, the Purchasers and the SPC’s (as defined in Section 9.1(e)) agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent required or requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies under any Transaction Document or any suit, action or proceeding relating to any Transaction Document or the enforcement of rights thereunder, (f) subject to obtaining a written agreement containing provisions substantially the same as those of this Section from the intended recipient of such Information, to any assignee of or participant in, or any prospective assignee of or participant in, any of its rights or obligations under this Agreement (including

any assignee or any prospective assignee of an SPC of the type described in the last sentence of Section 9.1(e)), (g) with the consent of the Seller or any other Transaction Party, (h) for purposes of Section 9.1(e) only, to any rating agency, (i) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Agent or any Purchaser on a nonconfidential basis from a source other than the Transaction Parties or (j) to any direct or indirect contractual counterparty in any swap, hedge or similar agreement (or to such contractual counterparty’s professional advisor) so long as the recipient of such Information agrees to be bound by the provisions of this Section. For the purposes of this Section, “Information” means all information received from the Transaction Parties relating to the Transaction Parties and their Affiliates or Subsidiaries or their respective businesses, other than any such information that is available to the Agent or any Purchaser on a nonconfidential basis prior to disclosure by any Transaction Party. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Notwithstanding any other provision herein, each Purchaser and the Agent (and each employee, representative or other agent of such party) may disclose to any and all Persons, without limitation of any kind, any information with respect to the “tax treatment” and “tax structure” (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of the transactions contemplated by the Transaction Documents and all materials of any kind (including opinions or other tax analyses) that are provided to the Agent or such Purchaser relating to such tax treatment and tax structure.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

(a) Any legal action or proceeding with respect to this Agreement or any other Transaction Document may be brought in the courts of the State of New York sitting in the Borough of Manhattan, the City of New York, or of the United States of America for the Southern District of New York, and, by execution and delivery of this Agreement, each of the Seller and the Servicer hereby accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of the aforesaid courts. The parties hereto hereby irrevocably waive any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, that any of them may now or hereafter have to the bringing of any such action or proceeding in such respective jurisdictions.

(b) Each of the Seller and the Servicer hereby irrevocably consents to the service of any and all legal process, summons, notices and documents in any suit, action or proceeding brought in the United States of America arising out of or in connection with this Agreement or any other Transaction Document by the mailing (by registered or certified mail, postage prepaid) or delivering of a copy of such process to the Seller or Servicer, as the case may be, at its address specified in Section 11.3. Each of the Seller and Servicer agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(c) Nothing contained in this Section 11.8 shall affect the right of the Agent or any Purchaser to serve process in any other manner permitted by law or commence legal proceedings or otherwise proceed against the Seller or Servicer or any other Transaction Party in any other jurisdiction.

This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which when taken together shall constitute one and the same agreement. Delivery by telecopier of an executed counterpart of a signature page to this Agreement shall be effective as delivery of an original executed counterpart of this Agreement.

It is the intention of the parties hereto that each Purchase and reinvestment shall convey to each Purchaser, to the extent of its Receivable Interests, an undivided ownership interest in the Pool Receivables, and the Related Security and Collections in respect thereof and that such transaction shall constitute a purchase and sale and not a secured loan for all purposes other than for federal income tax purposes. If, notwithstanding such intention, the conveyance of the Receivable Interests from the Seller to any Purchaser shall ever be recharacterized as a secured loan and not a sale, it is the intention of the parties hereto that this Agreement shall constitute a security agreement under applicable law, and the Seller hereby grants to the Agent for the benefit of itself and each such Purchaser a duly perfected first priority security interest in all of the Seller’s right, title and interest in, to and under the Pool Receivables and the Related Security and Collections in respect thereof, the Restricted Accounts and all proceeds thereof, free and clear of Liens (except for Permitted Liens) and Seller also hereby grants to the Agent for the benefit of itself and each Purchaser a duly perfected first priority security interest in all of the Seller’s right, title and interest in, to and under any Cash Assets and any cash collateral under this Agreement.

This Agreement and the other Transaction Documents contain a final and complete integration of all prior expressions by the parties hereto with respect to the subject matter hereof and shall constitute the entire agreement and understanding among the parties hereto with respect to the subject matter hereof and supersede all prior agreements and understandings, written or oral, relating to the subject matter hereof.

Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

Each of the parties hereto irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or any of the other Transaction Documents, the Purchases or the actions of the Agent or any Indemnified Party in the negotiation, administration, performance or enforcement hereof or thereof.

IN WITNESS WHEREOF, the parties have caused this Agreement to be executed by their respective officers thereunto duly authorized, as of the date above written.
