ARTICLE 2

The Loans

Section 2.01. Commitments. Subject to the terms and conditions and relying upon the representations and warranties herein set forth, each Lender agrees, severally and not jointly, to make Revolving Loans to the Borrowers from time to time on any Business Day during the Revolving Period in amounts such that (i) the Outstandings of such Lender shall at no time exceed the amount of its Commitment and (ii) the Total Outstandings shall at no time exceed the Maximum Facility Availability. Within the foregoing limits, the Borrowers may borrow, pay or prepay and reborrow Revolving Loans hereunder during the Revolving Period and subject to the terms, conditions and limitations set forth herein.

Section 2.02. Loans. Article 2 Each Revolving Loan shall be made as part of a Borrowing consisting of Revolving Loans made ratably by the Lenders in accordance with their respective Commitments; provided, however, that the failure of any Lender to make any Revolving Loan shall not in itself relieve any other Lender of its obligation to lend hereunder (it being understood, however, that no Lender shall be responsible for the failure of any other Lender to make any Loan to be made by such other Lender). The Loans comprising any Revolving Borrowing shall be in an aggregate principal amount which is an integral multiple of $1,000,000 and not less than the lesser of $10,000,000 and the remaining available balance of the Commitments.

(b) Each Revolving Borrowing shall be comprised entirely of LIBOR Loans or ABR Loans, as the Borrowers may request pursuant to Section 2.03. Each Lender may at its option make any LIBOR Loan by causing any branch or Affiliate of such Lender to make such Loan; provided, however, that any exercise of such option shall not affect the obligation of the Borrowers to repay such Loan in accordance with the terms of this Agreement; provided, further, that if the designation of any such foreign branch or Affiliate shall result in any costs, reductions or Taxes which would not otherwise have been applicable and for which such Lender would, but for this proviso, be entitled to request compensation under Section 2.15, 2.16 or 2.19, such Lender shall not be entitled to request such compensation unless it shall in good faith have determined such designation to be necessary or advisable to avoid any material disadvantage to it. Borrowings of more than one Type may be outstanding at the same time. For purposes of the foregoing, Borrowings having different Interest Periods, regardless of whether they commence on the same date, shall be considered separate Borrowings.

(c) Subject to Section 2.04 and paragraph (d) below, each Lender shall make its Loans on the proposed date or dates thereof (i) in the case of Loans other than Swingline Loans, by wire transfer of immediately available funds to the Administrative Agent in New York, New York, not later than 12:30 p.m., New York City time, and (ii) in the case of Swingline Loans, as provided for in Section 2.05. The Administrative Agent shall credit on such date the amounts so received to the general deposit account of the Borrowers Agent with the Administrative Agent or to another account specified by the Borrowers and acceptable to the Administrative Agent by 3:00 p.m., New York City time; provided that ABR Loans made to finance the reimbursement of an LC Disbursement shall be remitted by the Administrative Agent to the Fronting Bank; and provided, further, that if a Borrowing shall not occur on such date because any condition precedent herein specified shall not have been met, the Administrative Agent shall return the amounts so received to the respective Lenders. Revolving Loans shall be made by the Lenders ratably in accordance with their Commitments as provided in Section 2.17. Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Administrative Agent such Lenders portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the date of such Borrowing in accordance with this paragraph (c) and the Administrative Agent may, in reliance upon such assumption, make available to the Borrowers on such date a corresponding amount. If and to the extent that such Lender shall not have made such portion available to the Administrative Agent, such Lender, on the one hand, and the Borrowers, on the other hand, severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the date such amount is made available to the Borrowers until the date such amount is repaid to the Administrative Agent at (i) in the case of the Borrowers, the interest rate applicable to ABR Loans and (ii) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount shall be deemed to constitute such Lenders Loan as part of such Borrowing for purposes of this Agreement as if it were made on the date of such Borrowing. Nothing herein shall prejudice any rights that the Borrowers may have against any Lender as a result of any default by such Lender hereunder.

(d) Notwithstanding any other provision of this Agreement, the Borrowers shall not be entitled to request any Borrowing if the Interest Period requested with respect thereto would not comply with the limitations specified in the definition of Interest Period.

Section 2.03. Notice of Borrowings. Article 3 In order to request a Revolving Borrowing, the Borrowers shall give notice in writing (including telecopy or other electronic communication) (or telephone notice promptly confirmed in writing (including telecopy or other electronic communication)) to the Administrative Agent in the form of Exhibit B (i) in the case of a LIBOR Borrowing, not later than 12:30 p.m.., New York City time, three (3) Business Days before a proposed Borrowing and (ii) in the case of an ABR Borrowing, not later than 12:30 p.m., New York City time, on the Business Day of a proposed Borrowing.

(b) The Administrative Agent may waive any prior notice in connection with any Borrowing to be made on the date hereof. Any notice given pursuant to this Section shall be irrevocable and shall in each case refer to this Agreement and specify (x) whether such Borrowing is to be a LIBOR Borrowing or an ABR Borrowing; (y) the date of such Borrowing (which shall be a Business Day) and the amount thereof; and (z) if such Borrowing is to be a LIBOR Borrowing, the Interest Period with respect thereto. If no election as to the Type of Borrowing is specified in any such notice, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period with respect to any LIBOR Borrowing is specified in any such notice, then the Borrowers shall be deemed to have selected an Interest Period of one (1) months duration. The Administrative Agent shall promptly advise the Lenders of each notice given pursuant to this Section and of each Lenders portion of the requested Borrowing.

Section 2.04. Conversions and Continuations. Each Revolving Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a LIBOR Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrowers shall have the right at any time upon prior irrevocable telephonic notice (which shall be confirmed promptly in writing (including telecopy or other electronic communication)) to the Administrative Agent by the time that a Borrowing Request would be required under Section 2.03 if the Borrowers were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election, to convert such borrowing to a different Type of Borrowing, or in the case of a LIBOR Borrowing, to continue such Borrowing as a LIBOR Borrowing for an additional Interest Period, subject in each case to the following:

(a) if fewer than all the Loans comprising any Borrowing are to be converted or continued, such conversion or continuation shall be made pro rata among the Lenders in accordance with the respective Loans of such Lenders that are part of such Borrowing immediately prior to such conversion or continuation;

(b) in the case of a conversion or continuation of fewer than all the Loans comprising any Borrowing, the aggregate principal amount of Loans converted or continued shall be an amount that would be a permitted Borrowing amount for Loans of the same Type under the last sentence of Section 2.02(a);

(c) accrued interest on a LIBOR Loan (or portion thereof) being converted or continued shall be paid by the Borrowers at the time of conversion or continuation;

(d) if any LIBOR Loan is converted at a time other than the end of an Interest Period applicable thereto, the Borrowers shall pay any increased costs associated therewith pursuant to Section 2.16;

(e) the duration of any Interest Period shall comply with the limitations specified in the definition of Interest Period, and any portion of a LIBOR Loan for which the shortest available Interest Period would extend beyond such date shall be automatically converted at the end of the Interest Period at the time in effect into an ABR Loan, and, if applicable, the number of outstanding Interest Periods (after giving effect to any such conversion or continuation), shall comply with the limitations specified in the definition of Interest Period; and

(f) the Borrowers shall not be entitled to elect to convert any Loans to, or continue any Loans for an additional Interest Period as, LIBOR Loans if an Event of Default shall exist when the Borrowers deliver notice of such election to the Administrative Agent.

The Interest Period applicable to any LIBOR Loan resulting from a conversion of a Loan shall be specified by the Borrowers in the irrevocable notice of conversion delivered pursuant to this Section; provided, however, that if no such Interest Period shall be specified, the Borrowers shall be deemed to have selected an Interest Period of one (1) months duration. If the Borrowers shall not have given timely notice to continue any LIBOR Loan into a subsequent Interest Period (and shall not otherwise have given notice to convert such Loan), such Loan (unless repaid pursuant to the terms hereof) shall, subject to Section 4.01, automatically be continued as a LIBOR Loan with an Interest Period of one (1) months duration. The Administrative Agent shall promptly advise the applicable Lenders of any notice given pursuant to this Section and of each such Lenders portion of the continuation or conversion hereunder. This Section shall not apply to Swingline Borrowings, which may not be converted or continued.

Section 2.05. Swingline Loans. Article 4 Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to the Borrowers from time to time during the Revolving Period, in an aggregate principal amount at any time outstanding that will not result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding the Swingline Sublimit (ii) the Total Outstandings exceeding the Maximum Facility Availability. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrowers may borrow, prepay and reborrow Swingline Loans.

(b) The Borrowers may request a Swingline Loan, by notifying the Swingline Lender of such request by telephone (confirmed in writing (including telecopy or other electronic communication) if requested by the Swingline Lender), not later than 12:30 p.m., New York City time, on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested date (which shall be a Business Day) and amount of the requested Swingline Loan. The Swingline Lender shall make each Swingline Loan available to the Borrowers by means of a credit to the general deposit account of the Borrowers Agent with the Swingline Lender (or, in the case of a Swingline Loan made to finance the reimbursement of an LC Disbursement as provided in Section 2.06(f), by remittance to the Fronting Bank) by 3:00 p.m., New York City time, on the requested date of such Swingline Loan.

(c) The Swingline Lender may by written notice given to the Borrowers and the Administrative Agent not later than 10:00 a.m., New York City time, on any Business Day, require the Borrowers to give a Borrowing Request on such date for a Borrowing on the earliest date permitted by Section 2.03 of Revolving Loans in an amount sufficient to repay all outstanding Swingline Loans.

(d) Whether or not it shall have given a notice pursuant to Section 2.05(c), the Swingline Lender may by written notice given to the Administrative Agent not later than 10:00 a.m., New York City time, on any Business Day require the Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding; provided that if the aggregate principal amount of Swingline Loans outstanding on the last Business Day of any week exceeds $5,000,000, then the Swingline Lender shall deliver such notice to the Administrative Agent on such last Business Day of such week and require the Lenders to acquire participations on such last Business Day of such week in all of the Swingline Loans then outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which Lenders will participate. Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each Lender, specifying in such notice such Lenders Revolving Percentage of such Swingline Loan or Loans. Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such Lenders Revolving Percentage of such Swingline Loan or Loans. Each Lender acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.02 with respect to Revolving Loans made by such Lender (and Section 2.02 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Lenders. The Administrative Agent shall notify the Borrowers of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the Borrowers (or other party on behalf of the Borrowers) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear. Any payment by a Lender pursuant to this paragraph to purchase a participation in a Swingline Loan shall not constitute a Revolving Loan and shall not relieve the Borrowers of their obligation to repay such Swingline Loan.

Section 2.06. Letters of Credit. Article 5 Existing Letters of Credit. On the Effective Date, without further action by any party hereto, each Fronting Bank that has issued an Existing Letter of Credit shall be deemed to have granted to each Lender, and each Lender shall be deemed to have acquired from such Fronting Bank, a participation in each Existing Letter of Credit equal to such Lenders Revolving Percentage of (i) the aggregate amount available to be drawn under such Existing Letter of Credit and (ii) the aggregate amount of any outstanding reimbursement obligations in respect thereof. Such participations shall be on all the same terms and conditions as participations granted in Additional Letters of Credit under Section 2.06(e). With respect to each Existing Letter of Credit (i) if the relevant Fronting Bank has, prior to the Effective Date, sold a participation therein to a Lender, such Lender and Fronting Bank agree that such participation shall be automatically canceled on the Effective Date and (ii) if the relevant Fronting Bank has, prior to the Effective Date, sold a participation therein to any bank or financial institution that is not a Lender, such participation shall be cancelled upon the Administrative Agent receiving the written consent of such bank or financial institution to the effectiveness of this Agreement as contemplated by Section 4.02(c).

(b) Additional Letters of Credit. Subject to the terms and conditions set forth herein, the Borrowers may request the issuance of Additional Letters of Credit for their account, in a form reasonably acceptable to the Administrative Agent and the relevant Fronting Bank, at any time and from time to time during the period beginning on the Effective Date and ending on the thirtieth day prior to the Termination Date. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of the letter of credit application and any related documentation submitted by the Borrowers to, or entered into by the Borrowers with, the relevant Fronting Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(c) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of an Additional Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrowers shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the relevant Fronting Bank) to the relevant Fronting Bank and the Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of an Additional Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, the date of issuance, amendment, renewal or extension, the date on which such Letter of Credit is to expire (which shall comply with paragraph (d) of this Section), the amount of such Additional Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the relevant Fronting Bank, the Borrowers also shall submit a letter of credit application in a form reasonably acceptable to the relevant Fronting Bank in connection with any request for an Additional Letter of Credit. An Additional Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrowers shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension Article 6 the LC Exposure shall not exceed the LC Sublimit and Article 7 the Total Outstandings shall not exceed the Maximum Facility Availability. Within the foregoing limits and subject to the terms and conditions set forth herein, the relevant Fronting Bank agrees to issue such Additional Letters of Credit (or amend, renew or extend an outstanding Letter of Credit, as the case may be).

(d) Expiration Date. Each Additional Letter of Credit shall expire at or prior to the close of business on the date one (1) year after the date of the issuance of such Additional Letter of Credit (or, in the case of any renewal or extension thereof, one (1) year after such renewal or extension). If the Borrowers so request, the relevant Fronting Bank shall issue an Additional Letter of Credit that has automatic extension provisions (each, an Auto-Extension Letter of Credit); provided that any such Auto-Extension Letter of Credit must permit the relevant Fronting Bank to prevent any such extension at least once in each twelve (12) month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the Non-Extension Notice Date) in each such twelve (12) month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the relevant Fronting Bank, the Borrowers shall not be required to make a specific request to the relevant Fronting Bank for any such extension. Once an Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the relevant Fronting Bank to permit the extension of such Letter of Credit at any time to an expiry date not later than the first anniversary of the Termination Date; provided that the relevant Fronting Bank shall not permit any such extension if (i) it has determined that it would have no obligation at such time to issue such Letter of Credit in its extended form under the terms hereof or (ii) it has received notice (which may be by telephone or in writing) on or before the day that is five (5) Business Days before the Non-Extension Notice Date from the Administrative Agent, any Lender or any Borrower that one or more of the applicable conditions specified in Section 4.01 is not then satisfied.

(e) Participations. By the issuance of an Additional Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the relevant Fronting Bank or the Lenders, the relevant Fronting Bank hereby grants to each Lender, and each Lender hereby acquires from such Fronting Bank, a participation in such Letter of Credit equal to such Lenders Revolving Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the relevant Fronting Bank, such Lenders Revolving Percentage of each LC Disbursement made by such Fronting Bank and not reimbursed by the Borrowers on the date due as provided in paragraph (f) of this Section, or of any reimbursement payment required to be refunded to the Borrowers for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever; provided that such participations by a Lender shall not be construed as a waiver of any claims such Lender may have against the relevant Fronting Bank for gross negligence or willful misconduct (as finally determined by a court of competent jurisdiction).

(f) Reimbursement. If any Fronting Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrowers shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:30 p.m., New York City time, on the date that such LC Disbursement is made, if the Borrowers shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by the Borrowers prior to such time on such date, then not later than 12:30 p.m., New York City time, on the Business Day immediately following the day that the Borrowers receive such notice; provided that the Borrowers may, subject to the conditions to the Borrowing set forth herein, request in accordance with Section 2.03 or 2.05 that such payment be financed with an ABR Revolving Borrowing or Swingline Loan in an equivalent amount and, to the extent so financed, the Borrowers obligation to make such payment shall be discharged and replaced by the resulting ABR Revolving Borrowing or Swingline Loan. If the Borrowers fail to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrowers in respect thereof and such Lenders Revolving Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Revolving Percentage of the payment then due from the Borrowers, in the same manner as provided in Section 2.02 with respect to Loans made by such Lender (and Section 2.02 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the relevant Fronting Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrowers pursuant to this paragraph, the Administrative Agent shall distribute such payment to the relevant Fronting Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse such Fronting Bank, then to such Lenders and such Fronting Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse a Fronting Bank for any LC Disbursement (other than the funding of ABR Revolving Loans or a Swingline Loan as contemplated above) shall not constitute a Loan and shall not relieve the Borrowers of their obligation to reimburse such LC Disbursement.

(g) Obligations Absolute. The Borrowers obligation to reimburse LC Disbursements as provided in paragraph (f) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by any Fronting Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrowers obligations hereunder. None of the Administrative Agent, the Lenders nor any Fronting Bank, nor any of their Related Parties shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the relevant Fronting Bank; provided that the foregoing shall not be construed to excuse the relevant Fronting Bank from liability to the Borrowers to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrowers to the extent permitted by applicable law) suffered by the Borrowers that are caused by such Fronting Banks failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of any Fronting Bank (as finally determined by a court of competent jurisdiction), such Fronting Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the relevant Fronting Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(h) Disbursement Procedures. Each Fronting Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The relevant Fronting Bank shall promptly notify the Administrative Agent and the Borrowers by telephone (confirmed by telecopy or other electronic communication) of such demand for payment and whether such Fronting Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrowers of their obligation to reimburse such Fronting Bank and the Lenders with respect to any such LC Disbursement.

(i) Interim Interest. If any Fronting Bank shall make any LC Disbursement, then, unless the Borrowers shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrowers reimburse such LC Disbursement, at the rate per annum then applicable to ABR Revolving Loans; provided that, if the Borrowers fail to reimburse such LC Disbursement when due pursuant to paragraph (f) of this Section, then Section 2.11 shall apply. Interest accrued pursuant to this paragraph shall be for the account of the relevant Fronting Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (f) of this Section to reimburse such Fronting Bank shall be for the account of such Lender to the extent of such payment.

(j) Replacement of Fronting Bank. Any Fronting Bank may be replaced at any time by written agreement among the Borrowers, the Administrative Agent, the replaced Fronting Bank and the successor Fronting Bank. The Administrative Agent shall notify the Lenders of any such replacement of any Fronting Bank. At the time any such replacement shall become effective, the Borrowers shall pay all unpaid fees accrued for the account of the replaced Fronting Bank pursuant to Section 2.07(b). From and after the effective date of any such replacement, (v) the successor Fronting Bank shall have all the rights and obligations of the Fronting Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (vi) references herein to the term Fronting Bank shall be deemed to refer to such successor or to any previous Fronting Bank, or to such successor and all previous Fronting Banks, as the context shall require. After the replacement of a Fronting Bank hereunder, the replaced Fronting Bank shall remain a party hereto and shall continue to have all the rights and obligations of a Fronting Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue Additional Letters of Credit and, for the avoidance of doubt, no Letter of Credit issued by it prior to such replacement shall be renewed or extended.

(k) Cash Collateralization. If any Event of Default shall occur and be continuing and the maturity of the Revolving Loans shall be accelerated or the Commitments terminated as provided in Article 7, on the Business Day that the Borrowers receive notice from the Administrative Agent or Lenders with LC Exposure representing greater than 50% of the total LC Exposure demanding the deposit of cash collateral pursuant to this paragraph, the Borrowers shall deposit in the Cash Collateral Account an amount in cash equal to 105% of the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, (vii) upon the occurrence of any Event of Default with respect to any Borrower described in Section 7.01(f) or (viii) if any Letters of Credit remain outstanding and undrawn on the Termination Date and, in case of either (i) or (ii), a backstop letter of credit reasonably acceptable to the Fronting Bank shall not have been provided as collateral for such Letters of Credit. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrowers under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Such deposits shall, pending their application as provided below, be invested by the Administrative Agent, at the Borrowers risk and expense, in repurchase obligations with respect to United States of America Treasury securities or other high-quality overnight or short-term investments (which may include certificates of deposit of the Administrative Agent), and any interest earned through the investment of such deposits shall be for the Borrowers account and shall be added to the deposits held by the Administrative Agent under this Section and applied as provided herein. Moneys in such account shall be applied by the Administrative Agent to reimburse the relevant Fronting Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrowers for the LC Exposure at such time or, subject to the consent of Lenders with LC Exposure representing greater than 50% of the total LC Exposure, be applied to satisfy other obligations of the Borrowers under this Agreement. If the Borrowers are required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount, together with any interest earned thereon (to the extent not applied as aforesaid), shall be returned to the Borrowers within three (3) Business Days after all Events of Default have been cured or waived.

Section 2.07. Fees. (b) The Borrowers agree to pay to each Lender, through the Administrative Agent, on the second Business Day following each March 31, June 30, September 30 and December 31, commencing March 31, 2008, and on the second Business Day following the date on which the Commitment of such Lender shall be terminated as provided herein, a fee (the Unused Commitment Fee) at the Applicable Commitment Fee Rate on the daily average amount by which the Commitment of such Lender exceeded the sum of its outstanding Revolving Loans and its LC Exposure during the quarter then ended (or other period commencing on the Effective Date or ending on the Termination Date or any date on which the Commitment of such Lender shall be terminated, as applicable). The Unused Commitment Fee shall be computed on the basis of the actual number of days elapsed over a year of three hundred and sixty (360) days (including the first day but excluding the last day). The Unused Commitment Fee due to each Lender shall commence to accrue on the Effective Date and shall cease to accrue on the earlier of the Termination Date and the termination of the Commitment of such Lender as provided herein.

(b) The Borrowers agree to pay (i) to the Administrative Agent for the account of each Lender a participation fee (the L/C Fee) with respect to its participations in Letters of Credit, which shall accrue at the Applicable L/C Margin on the average daily amount of such Lenders LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lenders Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to each Fronting Bank, as applicable, a fronting fee, (the L/C Issuance Fee) which shall accrue at a rate of 0.25% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure. Participation fees and fronting fees shall be payable on the second Business Day following each March 31, June 30, September 30 and December 31, commencing March 31, 2008; provided that all such fees shall be payable on the second Business Day following the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. All participation fees and fronting fees shall be computed on the basis of a year of three hundred and sixty (360) days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c) The Borrowers agree to pay to the Administrative Agent, for its own account, collateral management, agency and administrative fees (the Administrative Fees) at the times and in the amounts heretofore agreed between them.

(d) The Borrowers agree to pay on the Effective Date to the Administrative Agent, for its own account and for the accounts of the Arrangers, the other Agents and the Lenders, fees in the amounts heretofore mutually agreed (the Effective Date Fees).

(e) All Fees shall be paid on the dates due, in immediately available funds, to the Administrative Agent for distribution, if and as appropriate, to the relevant Fronting Bank or among the Lenders. The Administrative Fees shall be paid on the dates due, in immediately available funds, to the Administrative Agent directly.

Section 2.08. Maturity of Loans; Mandatory Prepayments. (c) The Borrowers hereby agree that the outstanding principal balance of each Loan shall be payable on the Termination Date; provided that on each date that a Revolving Borrowing is made, the Borrowers shall repay all Swingline Loans borrowed prior to such date and then outstanding.

(b) Mandatory Prepayments.

(i) Upon the receipt by (or for the account of) any Loan Party of Net Proceeds in respect of any Prepayment Event, the Borrowers shall prepay the Loans in an amount equal to the lesser of (i) the outstanding principal amount of the Loans and (ii) such Net Proceeds in accordance with (and subject to) subsection (c) below. Each such prepayment shall be required to be made not later than the fifth Business Day following receipt of such Net Proceeds; provided that if the Net Proceeds in respect of any Prepayment Event arising from a Covered Disposition of Collateral are less than $25,000,000 or the Net Proceeds in respect of any Prepayment Event arising from receipt of Casualty Proceeds do not constitute Major Casualty Proceeds, no such prepayment shall be required until the amount of such Net Proceeds, together with the amount of all other Net Proceeds in respect of Prepayment Events arising from Covered Dispositions of Collateral or receipt of Casualty Proceeds, respectively, in respect of which no prepayment under this subsection (b) shall have theretofore been made because such Net Proceeds aggregated less than $25,000,000 or did not constitute Major Casualty Proceeds, as applicable, are equal to at least $25,000,000 or constitute Major Casualty Proceeds.

(ii) If at any date the Total Outstandings exceed the Maximum Facility Availability calculated as of such date, then not later than the next succeeding Business Day, the Borrowers shall be required to take one of the following actions (as elected by the Borrowers): (A) prepay the Loans, (B) deposit cash in the Cash Collateral Account or (C) a combination of (A) and (B), in each case in an amount equal to such excess so that the Total Outstandings no longer exceed the Maximum Facility Availability. So long as either (x) no Default exists or (y) Total Outstandings are zero, any cash so deposited shall be released to the Borrowers if and to the extent that Total Outstandings, after giving effect to such release, would not exceed the Maximum Facility Amount.

(iii) During each Sweep Period, all amounts collected in the Sweep Account will be applied to the repayment of Loans in accordance with (and subject to) subsection (c) below.

(i) Each payment of principal of the Loans shall be applied first to any outstanding Swingline Loans until the Swingline Loans shall have been repaid in full and then to Revolving Loans.

(ii) Each payment of principal of the Revolving Loans shall be applied ratably to the respective Revolving Loans of all Lenders.

(iii) Each payment of principal of the Revolving Loans pursuant to subsection (b) above shall be applied to outstanding ABR Loans up to the full amount thereof and then to outstanding LIBOR Loans.

(iv) Each payment of principal of LIBOR Loans shall be made together with interest accrued and unpaid on the amount repaid to the date of payment.

(v) So long as no Event of Default has occurred and is continuing, if subsection (b) would otherwise require prepayment of LIBOR Loans or portions thereof prior to the last day of the then current Interest Period therefor, each such prepayment may, if the Borrowers so elect by notice to the Administrative Agent, be deferred to such last day of the related Interest Period. In the event of a deferral pursuant to this subsection, cash in the amount of the required prepayment shall be deposited in the Cash Collateral Account on the date the required prepayment would otherwise have been required for application on the deferred payment date unless the Borrowers would have been able, had the required prepayment been made, to reborrow that amount consistent with Section 4.01. Any amounts deposited in the Cash Collateral Account pursuant to the previous sentence but not yet applied to repay a LIBOR Loan shall be released to the Borrowers on any date prior to the last day of the then current Interest Period if on such date (D) the Borrowers are able to reborrow the amount consistent with Section 4.01 or (E) Total Outstandings are zero.

(d) Each payment of the LIBOR Loans shall be applied to such Borrowings as the Borrowers may designate (or, failing such designation, as determined by the Administrative Agent).

(e) For the avoidance of doubt, no prepayment shall result in any reduction of the Lenders Commitments hereunder.

Section 2.09. Evidence of Debt. (d) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement.

(b) The Administrative Agent shall maintain accounts in which it will record (i) the amount of each Loan made hereunder, the Class and Type of each Loan and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrowers to each Lender hereunder, (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lenders share thereof and (iv) the amount of any interest thereon payable from the Borrowers to each Lender hereunder.

(c) The entries made in the accounts maintained pursuant to paragraphs (a) and (b) above shall, absent manifest error and to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrowers to repay the Loans in accordance with their terms.

(d) Notwithstanding any other provision of this Agreement, in the event any Lender shall request a Note evidencing the Loans made by it hereunder, the Borrowers shall deliver such a Note or Notes payable to such Lender.

Section 2.10. Interest on Loans. Article 8 Subject to the provisions of Section 2.11, each ABR Revolving Loan shall bear interest at a rate per annum equal to the sum of the Applicable Margin plus the Alternate Base Rate. Interest on each ABR Loan shall be payable on each applicable Interest Payment Date. The Alternate Base Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

(b) Subject to the provisions of Section 2.11, each LIBOR Loan shall bear interest at a rate per annum equal to the Adjusted LIBO Rate for the Interest Period in effect for such Loan plus the Applicable Margin. Interest on each LIBOR Loan shall be payable on each applicable Interest Payment Date (and, in the case of Revolving Loans, upon termination of the Commitments). The Adjusted LIBO Rate for each Interest Period shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error. The Administrative Agent shall promptly advise the Borrowers and each applicable Lender of such determination.

(c) Subject to the provisions of Section 2.11, each Swingline Loan shall bear interest at the rate per annum applicable to ABR Revolving Loans as provided in paragraph (a) above.

(d) Interest on each Loan shall accrue from and including the date on which such Loan is made and to but excluding the date such Loan is repaid.

(e) All computations of interest for ABR Loans when the Alternate Base Rate is determined by Citibanks base rate shall be made on the basis of 365 days or 366 days, as applicable, and actual days elapsed. All other computations of fees and interest shall be made on the basis of a three hundred and sixty (360)-day year and actual days elapsed.

Section 2.11. Interest on Overdue Amounts; Alternative Rate of Interest. (a) If the Borrowers shall default in the payment of interest on any Loan or any Fees or other amount (other than principal) becoming due hereunder, whether by scheduled maturity, notice of prepayment, acceleration or otherwise, the Borrowers shall on demand pay interest from and including the date of such default, to the extent permitted by law, on such defaulted amount (other than principal) up to (but not including) the date of actual payment (after as well as before judgment) at a rate per annum (computed as provided in Section 2.10(a)) equal to the rate then applicable to ABR Loans plus (but not in addition to the 2.00% increment contemplated by the proviso to the definition of Applicable Margin) 2.00% per annum.

(b) In the event, and on each occasion, that on the day two (2) Business Days prior to the commencement of any Interest Period for a LIBOR Borrowing the Administrative Agent shall have determined that deposits in the requested principal amounts of the LIBOR Loans are not generally available in the London interbank market to the Lenders or that reasonable means do not exist for ascertaining the LIBO Rate or that the rate at which such deposits are being offered will not adequately and fairly reflect the cost to the Lenders of making such LIBOR Loan, during such Interest Period, the Administrative Agent shall, as soon as practicable thereafter, give notice of such determination to the Borrowers and any request by the Borrowers for a LIBOR Borrowing shall, until the circumstances giving rise to such notice no longer exist, Article 9 if such notice relates to a Revolving Borrowing, be deemed a request for an ABR Borrowing; provided, however, that the Borrowers may withdraw any such request prior to the making of any such ABR Borrowing, or Article 10 if such notice relates to the conversion of any outstanding Borrowing to, or continuation of any outstanding Borrowing as, a LIBOR Borrowing, be deemed to be a request for a conversion to, or continuation as, an ABR Borrowing, as applicable. Each determination by the Administrative Agent hereunder shall be conclusive absent manifest error.

Section 2.12. Termination and Reduction of Commitments and Swingline Facility. (a) Unless previously terminated, the Commitments and the Swingline Facility shall be automatically and permanently terminated on the Termination Date.

(b) Upon at least three (3) Business Days prior irrevocable notice to the Administrative Agent (a copy of which the Administrative Agent shall promptly provide to each Lender), the Borrowers may at any time in whole permanently terminate, or from time to time in part permanently reduce, the Total Commitment; provided, however, that (i) each partial reduction of the Total Commitment shall be in an integral multiple of $1,000,000 and in a minimum principal amount of $5,000,000 and (ii) no such termination or reduction shall be made (A) which would reduce the Total Commitment to an amount less than the Total Outstandings or (B) which would reduce any Lenders Commitment to an amount that is less than such Lenders Outstandings. Notwithstanding the foregoing, a notice of termination or reduction of the Total Commitment delivered by the Borrowers may state that such notice is conditioned upon the effectiveness of other debt incurrences, equity issuances or asset sales, in which case such notice may be revoked by the Borrowers (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied.

(c) Each reduction in the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments.

Section 2.13. Optional Prepayment of Loans. (b) The Borrowers shall have the right at any time and from time to time to prepay any Borrowing, in whole or in part without premium or penalty, upon giving telephonic notice (which shall be confirmed promptly in writing (including telecopy or other electronic communication)) to the Administrative Agent (which shall promptly provide a copy to each Lender): (i) before 12:30 p.m., New York City time, at least two (2) Business Days prior to prepayment, in the case of LIBOR Loans and (ii) before 12:30 p.m., New York City time, on the date of prepayment, in the case of ABR Loans; provided, however, that (x) each such partial prepayment of LIBOR Loans shall be in a minimum principal amount of $10,000,000 and an integral multiple of $1,000,000 and (y) each such partial prepayment of Swingline Loans shall be in a minimum principal amount of $100,000 and an integral multiple of $100,000.

(b) On the date of any termination or reduction of the Total Commitment pursuant to Section 2.12, the Borrowers shall pay or prepay so much of the Revolving Borrowings as shall be necessary in order that the Total Outstandings will not exceed the Maximum Facility Availability after giving effect to such termination or reduction.

(c) Except to the extent otherwise specified by the Borrowers when making a prepayment, all prepayments under this Section 2.13 of Revolving Loans shall be applied to outstanding ABR Loans up to the full amount thereof and then shall be applied to outstanding LIBOR Loans up to the full amount thereof.

(d) All prepayments under this Section shall be subject to Section 2.16 but otherwise without premium or penalty. All prepayments of LIBOR Loans shall be accompanied by accrued interest on the principal amount being prepaid to the date of prepayment.

Section 2.14. Reserve Requirements; Change in Circumstances. (c) Notwithstanding any other provision herein (but subject to paragraph (d) below and Section 2.20), if after the date any Lender or Fronting Bank becomes a Lender or Fronting Bank hereunder any change in applicable law or regulation or in the interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof (whether or not having the force of law) shall change the basis of taxation of payments to any Lender or any Fronting Bank, as applicable, of the principal of or interest on any LIBOR Loan made by such Lender or any Letter of Credit or participation therein or any fees or other amounts payable hereunder (other than changes in respect of Taxes referred to in clause (a) or (b) of the definition of Excluded Taxes) or by any political subdivision or taxing authority therein), or shall impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of or credit extended by such Lender or Fronting Bank or shall impose on such Lender, such Fronting Bank or the London interbank market any other condition affecting this Agreement or LIBOR Loans made by such Lender or any Letter of Credit or participation therein, and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any such Loan or to increase the cost to such Lender or such Fronting Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or such Fronting Bank hereunder (whether of principal, interest or otherwise) in respect thereof by an amount deemed by such Lender to be material, then the Borrowers will pay to such Lender or such Fronting Bank, as the case may be, such additional amount or amounts as will compensate such Lender or such Fronting Bank for such additional costs incurred or reduction suffered.

(b) Subject to Section 2.20, if any Lender or any Fronting Bank shall have determined that the adoption after the date any Lender or Fronting Bank becomes a Lender or Fronting Bank hereunder of any law, rule, regulation or guideline regarding capital adequacy, or any change after such date in any of the foregoing or in the interpretation or administration of any of the foregoing by any Governmental Authority charged with the interpretation or administration thereof, or compliance by any Lender or any Fronting Bank (or any lending office of such Lender or Fronting Bank) or any Lenders or any Fronting Banks holding company with any request or directive regarding capital adequacy (whether or not having the force of law) made or promulgated after such date by any such Governmental Authority, has or would have the effect of reducing the rate of return on such Lenders or such Fronting Banks capital or on the capital of such Lenders or such Fronting Banks holding company, if any, as a consequence of its obligations under this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by any Fronting Bank, pursuant hereto to a level below that which such Lender or such Fronting Bank or such Lenders or such Fronting Banks holding company could have achieved but for such adoption, change or compliance (taking into consideration such Lenders or such Fronting Banks guidelines with respect to capital adequacy) by an amount deemed by such Lender or such Fronting Bank to be material, then from time to time the Borrowers shall pay to such Lender or such Fronting Bank such additional amount or amounts as will compensate such Lender or such Fronting Bank or such Lenders or such Fronting Banks holding company for any such reduction suffered.

(c) A certificate of each Lender or any Fronting Bank setting forth such amount or amounts as shall be necessary to compensate such Lender or Fronting Bank (or its participating banks or other entities pursuant to Section 10.07) as specified in paragraph (a) or (b) above, as the case may be, shall be delivered to the Borrowers and shall be conclusive absent manifest error. Except as provided in paragraph (d) below, the Borrowers shall pay each Lender or Fronting Bank the amount shown as due on any such certificate delivered by such Lender or Fronting Bank within thirty (30) days after receipt of the same. Each Lender or Fronting Bank shall submit such a certificate no more often than monthly; provided, however, that certificates with respect to amounts due with respect to identifiable Loans may be submitted at the ends of such Loans Interest Periods.

(d) Failure on the part of any Lender or Fronting Bank to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital shall not constitute a waiver of such Lenders or Fronting Banks rights with respect to any period to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital with respect to such period or any other period; provided, however, that neither any Lender nor any Fronting Bank shall be entitled to compensation under this Section 2.14 for any costs incurred or reductions suffered more than ninety (90) days prior to the date on which it shall have requested compensation therefor; provided further, that if the change in law or regulation or in the interpretation or administration thereof that shall give rise to any such costs or reductions shall be retroactive, then the ninety (90)-day period referred to above shall be extended to include the period of retroactive effect thereof. Notwithstanding any other provision of this Section 2.14, neither any Lender nor any Fronting Bank shall demand compensation for any increased cost or reduction referred to above if it shall not at the time be the general policy or practice of such Lender or such Fronting Bank to demand such compensation in similar circumstances under comparable provisions of other credit agreements, if any. If any Lender or any Fronting Bank shall receive as a refund any moneys from any source that it has listed on the certificate provided pursuant to (c) above as an increased cost, to the extent that the Borrowers have previously paid such increased cost to such Lender or such Fronting Bank, such Lender or Fronting Bank shall promptly forward such refund to the Borrowers without interest.

Section 2.15. Change in Legality. (d) Notwithstanding anything to the contrary herein contained (but subject to Section 2.20), if after the date of this Agreement any change in any law or regulation or in the interpretation thereof or any new law, regulation or interpretation by any Governmental Authority charged with the administration or interpretation thereof or any judgment, order or directive of any competent court, tribunal or authority shall make it unlawful for any Lender or its Applicable Lending Office to make or maintain any LIBOR Loan or to give effect to its obligations as contemplated hereby with respect to any LIBOR Loan (collectively, an Illegality), then, by written notice to the Borrowers and to the Administrative Agent, such Lender, so long as such Illegality continues to exist:

(i) may declare that LIBOR Loans will not thereafter be made by such Lender hereunder, whereupon any request by the Borrowers for a LIBOR Borrowing (x) shall, as to such Lender only, be deemed a request for an ABR Borrowing or (y) at the option of the Borrowers, shall be withdrawn as to the Lender prior to the time for making the Borrowing; and

(ii) shall promptly enter into negotiations with the Borrowers and negotiate in good faith to agree to a solution to such Illegality; provided, however, that if such an agreement has not been reached by the date at which such change in law is given effect with respect to the outstanding LIBOR Loans of such Lender, the Borrowers shall immediately, at the option of the Borrowers, either (A) prepay the affected Loans or (B) convert any such LIBOR Loan to an ABR Loan.

(b) For purposes of this Section 2.15, a notice by a Lender shall be effective as to each Loan, if lawful, on the last day of the then current Interest Period with respect thereto; provided, however, that such notice shall be effective on the date of receipt if there are no outstanding LIBOR Loans; provided further, that if it is not lawful for such Lender to maintain any Loan in its current form until the end of the Interest Period applicable thereto, then the notice shall be effective upon receipt.

(c) Each Lender that has delivered a notice of Illegality pursuant to paragraph (a) above agrees that it will notify the Borrowers as soon as practicable if the conditions giving rise to the Illegality cease to exist.

Section 2.16. Indemnity. The Borrowers agree to indemnify each Lender against any loss (other than loss of margin) or expense which such Lender may actually sustain or incur, and to pay any customary breakage charges such Lender may impose, as a consequence of (e) any payment, prepayment or conversion of a LIBOR Loan made to it required by any provision of this Agreement or otherwise made, or any transfer of any such Loan pursuant to Section 2.20(b), on a date other than the last day of the applicable Interest Period, (f) any default in payment or prepayment of the principal amount of any Loan made to it or any part thereof or interest accrued thereon, as and when due and payable (whether at scheduled maturity, by notice of prepayment, acceleration or otherwise), (g) the occurrence of any Event of Default, including any loss actually sustained or incurred or to be sustained or incurred in liquidating or employing deposits from third parties acquired to effect or maintain such Loan or any part thereof as a LIBOR Loan, (h) any failure by the Borrowers to fulfill on the date of any Borrowing hereunder the applicable conditions set forth in Article 4, (i) any failure of the Borrowers to borrow or to convert or continue any Loan made to it hereunder after irrevocable notice of such Borrowing, conversion or continuation has been given pursuant to Section 2.03, 2.04 or 2.05. Such loss or expense shall be the difference as reasonably determined by such Lender between (x) an amount equal to the principal amount of such LIBOR Loan being paid, prepaid, converted or transferred or not borrowed, converted or continued multiplied by a percentage per annum (computed on the basis of a three hundred and sixty (360)-day year and actual days remaining for the balance of the Interest Period applicable, or which would have been applicable, to such LIBOR Loan being paid, prepaid, converted, transferred or not borrowed, converted or continued) equal to the greater of (i) the Adjusted LIBO Rate applicable to such LIBOR Loan being paid, prepaid, converted or transferred or not borrowed, converted or continued or (ii) such Lenders cost of obtaining the funds for such LIBOR Loan being paid, prepaid, converted, transferred or not borrowed, converted or continued, but in the case of LIBOR Loans, not in excess of the Adjusted LIBO Rate applicable to such Loan plus 1/16th of 1% per annum, and (y) any lesser amount that would be realized by such Lender in reemploying the funds received in payment, prepayment, conversion or transfer or as a result of the failure to borrow, convert or continue during the period from the date of such payment, prepayment, conversion or transfer or failure to borrow, convert or continue to the end of the Interest Period applicable to such LIBOR Loan at the interest rate that would apply to an interest period of approximately such duration. Any such Lender shall provide to the Borrowers a statement explaining the amount of any such loss or expense, which statement shall, in the absence of manifest error, be conclusive.

Section 2.17. Pro Rata Treatment. Each Revolving Borrowing, each payment of the Unused Commitment Fee and each reduction of the Total Commitment shall be allocated among the Lenders in accordance with their respective Revolving Percentages. Except as required under Section 2.15, each payment or prepayment of principal of any Borrowing and each continuation or conversion of any Borrowing shall be allocated pro rata among the Lenders in accordance with the respective principal amounts of their outstanding Loans comprising such Borrowing. Each payment of interest on any Borrowing shall be allocated pro rata among the Lenders in accordance with the respective amounts of accrued and unpaid interest on their outstanding Loans comprising such Borrowing. Each payment of interest on any Swingline Borrowing or LC Disbursement shall be allocated in accordance with Sections 2.05 and 2.06, respectively.

Section 2.18. Sharing of Setoffs. Each Lender agrees that if it shall, through the exercise of a right of bankers lien, setoff or counterclaim or pursuant to a secured claim under Section 506 of Title 11 of the United States Code or other security or interest arising from, or in lieu of, such secured claim, received by such Lender under any applicable bankruptcy, insolvency or other similar law or otherwise, obtain payment (voluntary or involuntary) in respect of any Loans or participations in LC Disbursements or Swingline Loans as a result of which the unpaid principal portion of its Loans or participations in LC Disbursements or Swingline Loans shall be proportionately less than the unpaid principal portion of the Loans or participations in LC Disbursements or Swingline Loans of any other Lender, it shall be deemed simultaneously to have purchased from such other Lender at face value, and shall promptly pay to such other Lender the purchase price for, a participation in the Loans or participations in LC Disbursements or Swingline Loans of such other Lender, so that the aggregate unpaid principal amount of such Loans or participations in LC Disbursements or Swingline Loans and participations in the foregoing held by each Lender shall be in the same proportion to the aggregate unpaid principal amount of all such Loans or participations in LC Disbursements or Swingline Loans then outstanding as the principal amount of its Loans or participations in LC Disbursements or Swingline Loans prior to such exercise of bankers lien, setoff or counterclaim or other event was to the principal amount of all such Loans or participations in LC Disbursements or Swingline Loans outstanding prior to such exercise of such bankers lien, setoff or counterclaim or other event; provided, however, that (i) if any such purchase or adjustments shall be made pursuant to this Section 2.18 and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest and (ii) the provisions of this Section shall not be construed to apply to any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements or Swingline Loans to any assignee or participant other than a Loan Party or any Affiliate thereof. Each Borrower expressly consents to the foregoing arrangements and agrees, to the fullest extent it may effectively do so under applicable law, that any Lender holding a participation in a Loan made to it or participations in LC Disbursements or Swingline Loans deemed to have been so purchased may exercise any and all rights of bankers lien, setoff or counterclaim with respect to any and all moneys owing by such Borrower to such Lender by reason thereof as fully as if such Lender had made a Loan directly to such Borrower in the amount of such participation.

Section 2.19. Taxes. (j) Any and all payments by or on account of any obligation of the Borrowers hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrowers shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender (which term, as used in this Section, shall include any assignee or transferee of a Lender, including any participation holder, subject to Section 10.07 (any such Person, a Transferee)) or Fronting Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrowers shall make such deductions and (iii) the Borrowers shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, the Borrowers shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Borrowers shall indemnify each Agent, each Lender and Fronting Bank, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by such Agent, such Lender or Fronting Bank, as the case may be on account of any obligation of the Borrowers hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrowers by an Agent, a Lender or a Fronting Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or Fronting Bank, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrowers to a Governmental Authority, the Borrowers shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrowers are located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrowers (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrowers as will permit such payments to be made without withholding or at a reduced rate. Each Lender and Agent that is a United States person (within the meaning of Section 7701(a)(3) of the Code shall provide an IRS Form W-9 to the Agent and Borrowers at the times and in the manners described above with respect to the other withholding forms; provided, however, that a Person that the Borrowers may treat as an exempt recipient (within the meaning of the Treasury Regulations Section 1.6049-4(c) (without regard to the third sentence thereof) shall not be required to deliver an IRS Form W-9, except to the extent necessary to avoid U.S. withholding taxes under Treasury Regulations Section 1.1441-1.

(f) If an Agent, a Lender or a Fronting Bank shall become aware that it is entitled to receive a refund in respect of Indemnified Taxes or Other Taxes for which it shall have received payment from the Borrowers under this Section, it shall promptly notify the Borrowers of the availability of such refund and shall, within ten (10) days after receipt of a request by the Borrowers, apply for such refund at the Borrowers expense. If an Agent, any Lender or any Fronting Bank shall receive a refund in respect of any such Indemnified Taxes or Other Taxes, it shall promptly repay such refund (including any penalties or interest received with respect thereto) to the Borrowers, net of all out-of-pocket expenses of such Agent, such Lender or Fronting Bank, provided that the Borrowers, upon the request of such Agent, such Lender or Fronting Bank, agrees to return such refund (plus penalties, interest or other charges) to such Agent, such Lender or Fronting Bank in the event such Agent, such Lender or Fronting Bank shall be required to repay such refund.

Section 2.20. Duty to Mitigate; Assignment of Commitments Under Certain Circumstances. (k) If any Lender (or Transferee) claims any additional amounts payable pursuant to Section 2.14 or exercises its rights under Section 2.15 or if the Borrowers are required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.19, then such Lender 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 Borrowers, or to change the jurisdiction of its Applicable Lending Office 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 Lender (or Transferee), be otherwise disadvantageous to such Lender (or Transferee).

(b) In the event that any Lender shall have delivered a notice or certificate pursuant to Section 2.14 or 2.15, or the Borrowers shall be required to make additional payments to any Lender under Section 2.19, the Borrowers shall have the right, at its own expense (which shall include the processing and recordation fee referred to in Section 10.07(b)), upon notice to such Lender and the Administrative Agent, to require such Lender to transfer and assign without recourse (in accordance with and subject to the restrictions contained in Section 10.07) all its interests, rights and obligations hereunder to another financial institution approved by the Administrative Agent, and each Fronting Bank and the Swingline Lender (which approval shall not be unreasonably withheld) which shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided, however, that (i) no such assignment shall conflict with any law, rule or regulation or order of any Governmental Authority and (ii) the assignee or the Borrowers shall pay to the affected Lender in immediately available funds on the date of such assignment the outstanding principal of its Loans and participations in LC Disbursements and Swingline Loans, accrued interest thereon, accrued fees and all other amounts accrued for its account or owed to it hereunder (including the additional amounts asserted and payable pursuant to Section 2.14 or 2.19, if any).

Section 2.21. Optional Increase In Commitments. At any time the Borrowers, may, if they so elect, increase the aggregate amount of the Commitments, either by designating a financial institution not theretofore a Lender (a New Lender) to become a Lender (such designation to be effective only with the prior written consent of the Administrative Agent, which consent will not be unreasonably withheld or delayed), or by agreeing with an existing Lender that such Lenders Commitment shall be increased. Upon execution and delivery by the Borrowers and such Lender or other financial institution of an instrument in form reasonably satisfactory to the Administrative Agent, such existing Lender shall have a Commitment as therein set forth or such other financial institution shall become a Lender with a Commitment as therein set forth and all the rights and obligations of a Lender with such a Commitment hereunder; provided:

(a) that the Borrowers shall provide prompt notice of such increase to the Administrative Agent, who shall promptly notify the Lenders;

(b) that any such increase shall be in an amount greater than or equal to $50,000,000;

(c) that immediately after such increase is made, the aggregate amount of increases in the Commitments pursuant to this Section 2.21, when combined with the aggregate amount of increases in the commitments under the 2007 RPA pursuant to Section 2.19 thereof, shall not exceed $600,000,000; and

(d) that the Borrowers may elect to increase the aggregate amount of the Commitments pursuant to this Section 2.21 no more than four times in total.

On the effective date of any increase in the aggregate amount of the Commitments pursuant to this Section 2.21, (i) each New Lender shall pay to the Agent an amount equal to its pro rata share of the aggregate outstanding Loans and (ii) any Lender (an Increasing Lender) whose Commitment has been increased shall pay to the Administrative Agent an amount equal to the increase in its pro rata share of the aggregate outstanding Loans, in each case such payments shall be for the account of each other Lender. Upon receipt of such amount by the Administrative Agent, (i) each other Lender shall be deemed to have ratably assigned that portion of its outstanding Loans that is being reduced to the New Lenders and the Increasing Lenders in accordance with such Lenders new Commitment or the increased portion thereof as applicable, and (ii) the Administrative Agent shall promptly distribute to each other Lender its ratable share of the amounts received by the Administrative Agent pursuant to this paragraph.

ARTICLE 8

Administrative Agent

Each of the Lenders and Fronting Banks irrevocably authorizes the Administrative Agent to take such action on its behalf and to exercise such powers under the Loan Documents as are specifically delegated to the Administrative Agent by the terms thereof together with such powers as are reasonably incidental thereto. The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents selected and appointed by such Administrative Agent. Each of the Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through Affiliates or its or its Affiliates employees. The exculpatory provisions of the following paragraphs shall apply to any such sub-agent, to the Affiliates of the Administrative Agent and any such sub-agent and to the directors, officers and employees of the Administrative Agent, any such sub-agent and their respective Affiliates.

The Administrative Agent is hereby expressly authorized and directed by the Lenders to the extent provided in this Agreement, without hereby limiting any implied authority, (a) to receive on behalf of the Lenders all payments of principal of and interest on the Loans and all other amounts due to the Lenders under the Loan Documents, and promptly to distribute to each Lender its proper share of each payment so received; (b) to give notice on behalf of each of the Lenders to the Borrowers of any Event of Default specified in this Agreement of which the Administrative Agent has actual knowledge acquired in connection with its agency hereunder; and (c) to distribute to each Lender copies of all notices, financial statements and other materials delivered by the Borrowers pursuant to the Loan Documents as received by the Administrative Agent.

Neither the Administrative Agent nor any of their directors, officers, employees or agents shall be liable as such for any action taken or omitted to be taken by it or them under the Loan Documents or in connection therewith (a) at the request or with the approval of the Required Lenders (or, if otherwise specifically required hereunder, the consent of all the Lenders) or (b) in the absence of its or their own bad faith, gross negligence or willful misconduct. Each Lender acknowledges that it has decided to enter into this Agreement and to extend the Loans hereunder based on its own analysis of the creditworthiness of the Borrowers and agrees that the Administrative Agent shall bear no responsibility for such creditworthiness.

114

The Administrative Agent shall not be responsible in any manner to any of the Lenders for the effectiveness, enforceability, genuineness, validity or due execution of the Loan Documents or any other agreements or certificates, requests, financial statements, notices or opinions of counsel or for any recitals, statements, warranties or representations contained in the Loan Documents or in any such instrument or be under any obligation to ascertain or inquire as to the performance or observance of any of the terms, provisions, covenants, conditions, agreements or obligations of the Loan Documents or any other agreements on the part of any Loan Party and, without limiting the generality of the foregoing, the Administrative Agent shall, in the absence of knowledge to the contrary, be entitled to accept any certificate furnished pursuant to any Loan Document as conclusive evidence of the facts stated therein and shall be entitled to rely on any note, notice, consent, certificate, affidavit, letter, telegram, teletype or telecopy message, statement, order or other document which it reasonably believes to be genuine and correct and to have been signed or sent by the proper Person or Persons. It is understood and agreed that the Administrative Agent may exercise its rights and powers under other agreements and instruments to which it is or may be a party and engage in other transactions with Lyondell or any Subsidiary or other Affiliate as though it were not the agent of the Lenders hereunder.

The Administrative Agent may consult with legal counsel selected by it in connection with matters arising under the Loan Documents and any action taken or suffered in good faith by it in accordance with the opinion of such counsel shall be full justification and protection to it. The Administrative Agent may exercise any of its powers and rights and perform any duty under the Loan Documents through agents or attorneys.

The Lenders shall ratably, in accordance with their Credit Exposures at the time of demand for indemnification hereunder, indemnify the Administrative Agent, in its capacity as agent on behalf of the Lenders (to the extent not reimbursed by the Borrowers pursuant to the terms hereof and without limiting the obligations of the Borrowers to do so) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as results from such Administrative Agents gross negligence or willful misconduct) that such Administrative Agent may suffer or incur in connection with this Agreement or any action taken or omitted by it under the Loan Documents.

Subject to the appointment and acceptance of a successor Administrative Agent as provided below, the Administrative Agent may resign at any time by notifying the Lenders, the Fronting Banks and the Borrowers. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent with the consent of the Borrowers, such consent not to be unreasonably withheld. If no successor Administrative Agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent which shall be a bank having an office (or an Affiliate with an office) in New York, New York, with a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor bank, such successor shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. After any Administrative Agents resignation hereunder, the provisions of this Article shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Administrative Agent.

115

The Lenders hereby acknowledge that the Administrative Agent shall not be under any duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement unless it shall be requested in writing to do so by the Required Lenders or, where required, all the Lenders.

No Agent other than the Administrative Agent shall have any responsibility, obligation or liability whatsoever under the Loan Documents in such capacity (other than as set forth in Section 10.14).

The Obligors

Section 9.01. Appointment and Authorization of Borrowers Agent.

The obligations of each of the Borrowers under the Loan Documents shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by:

(i) any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of any other Loan Party under any Loan Documents, by operation of law or otherwise;

(vi) any other act or omission to act or delay of any kind by any other Loan Party or any other corporation or Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of the Borrowers obligations hereunder.

Section 9.03. Contribution; Subordination. Each Borrower (a Contributing Borrower) agrees that when a payment shall be made by any other Borrower under the Loan Documents upon enforcement thereof (such other Borrower, the Claiming Borrower), the Contributing Borrower shall indemnify the Claiming Borrower in an amount equal to the amount of such payment multiplied by a fraction of which the numerator shall be the net worth of the Contributing Borrower on December 31, 2006 (or, with respect to any Borrower becoming a party hereto pursuant to Section 9.04, the date such Contributing Borrower became a Borrower) and the denominator shall be the aggregate net worth of all Borrowers on December 31, 2006 (or, in the case of any Borrower becoming a party hereto pursuant to Section 9.04, the date such Borrower became a Borrower). All rights of the Borrowers under this Section and any other rights of indemnity, contribution or subrogation under applicable law or otherwise shall be fully subordinated to the indefeasible payment in full in cash of all amounts payable by the Borrowers pursuant to the Loan Documents.

Section 9.04. Limitation on Obligations of Borrowers.

118

Notices and other communications to the Lenders hereunder may be delivered or furnished by electronic communications pursuant to procedures approved by the Administrative Agent; provided that the foregoing shall not apply to notices pursuant to Article 2 unless otherwise agreed by the Administrative Agent and the applicable Lender. The Administrative Agent or Lyondell may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications.

Section 10.02. No Waivers; Amendments. (a) No failure or delay of any Fronting Bank, any Agent or any Lender in exercising any power or right under any Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Agents, the Fronting Banks and the Lenders under the Loan Documents are cumulative and not exclusive of any rights or remedies which they would otherwise have. Except as may be otherwise expressly provided herein, no waiver of any provision of this Agreement nor any consent to any departure by any Borrower therefrom shall in any event be effective unless the same shall be in writing and signed by the Required Lenders (unless otherwise specified herein), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on the Borrowers in any case shall entitle the Borrowers to any other or further notice or demand in similar or other circumstances. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether any Agent, any Lender or any Fronting Bank may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any Exhibit or Schedule hereto may be amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrowers Agent on behalf of the Borrowers and by the Required Lenders; provided, however, that no such agreement shall (i) increase the Commitment of any Lender, or subject any Lender to any additional obligation, without the prior written consent of such Lender, (ii) postpone any scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any Fee payable hereunder, or reduce the amount of, waive or excuse any such payment, or reduce the Applicable Margin, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iii) amend or modify or otherwise affect the rights or duties of any Agent, any Fronting Bank or the Swingline Lender without its prior written consent, (iv) amend or modify the definition of Required Lenders, or otherwise change the percentage of Commitments or Credit Exposures, or the number of Lenders, which shall be required for the Lenders or any of them to take action hereunder, or increase the amount of the Total Commitment, or amend or modify Section 2.17, this Section 10.02 or Section 10.07, in each case without the prior written consent of each Lender or (v) amend or modify the definitions of Available Inventory, Collateral Availability, Eligible Inventory, Excess Availability, Ineligible Inventory, SF Excess Availability, Total Collateral Availability or Total Excess Availability, or amend, or waive a Default arising under, Section 7.01(n), in each case without the prior written consent of Lenders having aggregate Credit Exposures representing at least 662/3% of the sum of all Credit Exposures at such time; provided that any increase in any percentage set forth in the definition of Available Inventory, or any amendment of the definition of Available Inventory that would have the effect of so increasing any such percentage, shall require the prior written consent of each Lender. Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder, except that the Commitment of such Defaulting Lender may not be increased or decreased without the consent of such Defaulting Lender (it being understood that a waiver of any condition precedent set forth in Article IV or waiver of any Default, mandatory prepayment or mandatory reduction of the Commitments shall not constitute an extension or increase of any Commitments).

119

(c) Any provision of the Collateral Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by each Loan Party thereto whose consent to such amendment or waiver is required by the terms of such Collateral Document and by and the Administrative Agent with the consent of the Required Lenders; provided that no such amendment or waiver shall, unless signed by all the Lenders, effect or permit a release of, or the consensual subordination of the Liens of the Collateral Documents on, all or substantially all of the Collateral or release any Loan Party from its obligations under the Loan Documents. Notwithstanding the foregoing, Collateral (but not the proceeds thereof) shall be released from the Lien of the Collateral Documents, and a Loan Party (other than Lyondell) shall be released from such obligations, from time to time as necessary to effect any sale of assets, including the sale of a Subsidiary Loan Party, permitted by the Loan Documents, and the Administrative Agent shall execute and deliver all release documents reasonably requested to evidence such release (without the requirement of consent from any Lender)

(d) If, in connection with any proposed amendment, modification, waiver or termination requiring the consent of all affected Lenders, the consent of the Required Lenders is obtained but the consent of other Lenders whose consent is required is not obtained (any such Lender whose consent is not obtained being referred to as a Non-Consenting Lender), then, so long as the Lender that is the same entity as the Administrative Agent is not a Non-Consenting Lender, at the Borrowers request, the Administrative Agent in its sole discretion (but shall have no obligation) or an Eligible Assignee with the Administrative Agent's consent (not to be unreasonably withheld) to purchase from such Non-Consenting Lender, and such Non-Consenting Lender agrees that it shall, upon the Administrative Agents request, sell and assign to the Lender that is the same entity as the Administrative Agent or to such Eligible Assignee, all of the Commitment and Loans of such Non-Consenting Lender for an amount equal to the outstanding principal amount of the Loans by the Non-Consenting Lender plus all accrued interest 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.

120

(e) It is understood that the operation of Section 2.21 in accordance with its terms is not an amendment subject to this Section 10.02.

(f) Notwithstanding the foregoing, any Loan Document may be amended by the Administrative Agent and the Borrowers to correct any typographical error or similar defect.

Section 10.03. Payments. Except as otherwise provided in this Agreement, all payments to be made by the Borrowers to the Lenders hereunder shall be made to the Administrative Agent in immediately available funds at Citibank, N.A., 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Xxxxx Xxxxx (Account Number 3685-2248, ABA 000000000 and Reference: LyondellBasell Industries) not later than 12:30 p.m., New York City time, on the date due.

Upon receipt of any payment for the accounts of the Lenders hereunder, the Administrative Agent will promptly distribute to each Lender its share of such payment.

Section 10.04. Governing Law; Submission to Jurisdiction. (b) THIS AGREEMENT SHALL BE CONSTRUED AND INTERPRETED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

(b) To the extent it may effectively do so under applicable law, each Borrower (i) irrevocably submits to the nonexclusive jurisdiction of any New York State or Federal court sitting in the Borough of Manhattan, The City of New York, over any suit, action or proceeding arising out of or relating to any Loan Document or any other document contemplated thereby, and (ii) irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

121

(c) Each Borrower agrees, to the fullest extent it may effectively do so under applicable law, that a judgment in any suit, action or proceeding of the nature referred to in paragraph (b) above brought in any such court shall be conclusive and binding upon such Borrower and may be enforced in the courts of the United States of America or the State of New York (or any other courts to the jurisdiction of which such Borrower is or may be subject) by a suit upon such judgment.

(d) To the extent it may effectively do so under applicable law, each Borrower consents to process being served in any suit, action or proceeding of the nature referred to in paragraph (b) by mailing a copy thereof by registered or certified mail, postage prepaid, return receipt requested, to the address of such Borrower set forth or referred to in Section 10.01. To the extent it may effectively do so under applicable law, each Borrower agrees that such service (iii) shall be deemed in every respect effective service of process upon such Borrower in any such suit, action or proceeding and (iv) shall be taken and held to be valid personal service upon and personal delivery to such Borrower.

(e) Nothing in this Section 10.04 shall affect the right of any Agent or Lender to serve process in any manner permitted by law, or limit any right that any Agent or Lender may have to bring proceedings against any Borrower in the courts of any jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction.

Section 10.05. Expenses; Documentary Taxes; Indemnity. i) The Borrowers shall pay (v) all reasonable out of pocket expenses incurred by the Administrative Agent, the Fronting Banks and their respective Affiliates, including the reasonable fees, charges and disbursements of Xxxxx Xxxx & Xxxxxxxx, special counsel for the Agents and any local counsel retained by them, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of the Loan Documents or any amendments, modifications or waivers of the provisions thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (vi) all reasonable out of pocket expenses incurred by the Fronting Banks in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (vii) all reasonable out of pocket expenses incurred by the Administrative Agent, the Fronting Banks or any Lender, including the reasonable fees, charges and disbursements of any counsel for the Administrative Agent, the Fronting Banks or any Lender, in connection with the enforcement or protection of its rights in connection with any Loan Document, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder, including all such out of pocket expenses incurred during any workout or restructuring in respect of such Loans or Letters of Credit. It is understood that reimbursement of the Administrative Agent in respect of matters covered by Section 5.14(b)(iii) of this Agreement is subject to the applicable limitations specified therein.

122

(b) The Borrowers shall indemnify each Agent, each Fronting Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an Indemnitee) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of any actual or threatened claim, litigation, investigation or proceeding, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto, relating to (viii) the execution or delivery of the Loan Documents or any agreement or instrument contemplated thereby, the performance by the parties hereto of their respective obligations under the Loan Documents or the consummation of the transactions contemplated thereby, (ix) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by a Fronting Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), or (x) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by Lyondell or any of its Subsidiaries, or any Environmental Liability related in any way to Lyondell or any of its Subsidiaries; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses resulted from the gross negligence or willful misconduct of such Indemnitee. Without limiting the generality of the foregoing, each Borrower hereby waives all rights for contribution or any other rights of recovery with respect to liabilities, losses, damages, costs and expenses arising under or related to Environmental and Safety Laws that it might have by statute or otherwise against any Indemnitee. No Indemnitee shall be liable for any damages arising from the use by others of any information or other materials obtained through IntraLinks or other similar information transmission systems in connection with this Agreement, nor shall any Indemnitee or the Borrowers or any Subsidiary have any liability for any special, punitive, indirect or consequential damages relating to this Agreement or any other Loan Document or arising out of its activities in connection herewith or therewith (whether before or after the Effective Date).

(c) The provisions of this Section 10.05 shall remain operative and in full force and effect regardless of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of the Loans, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan Document, or any investigation made by or on behalf of the Lenders or the Administrative Agent. All amounts due under this Section 10.05 shall be payable on written demand therefor.

123

Section 10.06. Survival of Agreements, Representations and Warranties, Etc. All warranties, representations and covenants made by any Loan Party herein or in any certificate or other instrument delivered by any Loan Party or on its behalf in connection with the Loan Documents shall be considered to have been relied upon by the Lenders and shall survive the making of the Loans and issuance of any Letters of Credit herein contemplated regardless of any investigation made by the Lenders or the Agents or on their behalf and shall continue in full force and effect so long as any amount due or to become due hereunder is outstanding and unpaid. The right of each Lender to receive payments pursuant to Sections 2.14, 2.16 and 2.19 shall survive the termination of this Agreement and the repayment of the Loans.

Section 10.07. Successors and Assigns. (c) This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns (including any Affiliate of a Fronting Bank that issues any Letter of Credit). No Borrower may assign or transfer any of its rights or obligations hereunder without the prior written consent of all of the Lenders (in the case of Lyondell) or the Administrative Agent (in the case of any other Borrower).

(b) Each Lender may assign all or a portion of its interests, rights and obligations under this Agreement (including all or a portion of its Commitment (if still in existence) and the Loans at the time owing to it); provided, however, that (i) except in the case of an assignment by a Lender to an Affiliate of such Lender, to another Lender or to a Related Fund of a Lender, the Borrowers and the Administrative Agent (and, in the case of an assignment of all or a portion of a Commitment or any Lenders obligations in respect of its LC Exposure or Swingline Exposure, regardless of the identity of the assignee, each Fronting Bank and the Swingline Lender) must consent to such assignment in writing (which consent may not be unreasonably withheld or delayed), (ii) each such assignment shall be of a constant, and not a varying, percentage of all the assigning Lenders rights and obligations under this Agreement as a Lender, (iii) after giving effect to any such assignment, (A) the aggregate amount of the Credit Exposure of the assigning Lender (together with its Related Funds and its Affiliates) shall be either (x) $0 or (y) $10,000,000 or more and (B) the aggregate amount of the Credit Exposure of the assignee Lender (together with its Related Funds and its Affiliates) shall be in the case of a Lender, $10,000,000 or more (or, in any case, any other smaller amount agreed upon by the Administrative Agent and the Borrowers); and (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent for its acceptance and recording in the Register an Assignment and Acceptance, together with (except in the case of assignment to another Lender or an Affiliate or a Related Fund of a Lender) a processing and recordation fee of $3,500 (provided that only one such fee shall be required in the case of multiple assignments by a Lender on a single day to funds managed or advised by the same investment advisor if such funds are not Lenders hereunder); and provided, further, that any consent of the Borrowers otherwise required under this paragraph shall not be required if an Event of Default has occurred and is continuing. The Credit Exposures held by or assigned to or by any Person and its Related Funds shall be aggregated for purposes of determining compliance with the amount thresholds specified in this Section. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, which effective date shall be (unless waived by the Administrative Agent) at least five (5) Business Days after the execution thereof, (A) the assignee thereunder shall be a party hereto, and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and (B) the assignor thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of the assignors rights and obligations under this Agreement, the assignor shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.14, 2.16 and 10.05 as well as to any interest and Unused Commitment Fee accrued for its account hereunder and not yet paid).

124

(c) By executing and delivering an Assignment and Acceptance, the assignor and the assignee thereunder shall be deemed to confirm to and agree with each other and the Borrowers as follows: (v) such assignor warrants that it is the legal and beneficial owner of the interest being assigned free and clear of any adverse claim; (vi) except as set forth in clause (i) above, the assignor makes no other 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 instrument or document furnished pursuant hereto or thereto, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, or any other instrument or document furnished pursuant hereto or thereto, or the financial condition of the Borrowers or the performance or observance by the Borrowers of any of their Obligations under this Agreement or any other instrument or document furnished pursuant hereto or thereto; (vii) such assignee represents and warrants that it is legally authorized to enter into such Assignment and Acceptance; (viii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements described in Section 5.01 or the most recent financial statements delivered pursuant to Section 5.01, as applicable, and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (ix) such assignee will independently and without reliance upon the assignor and based on such documents and information as it shall deem appropriate at the time continue to make its own credit decisions in taking or not taking action under this Agreement; (x) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents, as are delegated to such Agent by the terms thereof, together with such powers as are reasonably incidental thereto; and (xi) such assignee agrees that it will, to the extent of the interest assigned to it, perform in accordance with their terms all the obligations which by the terms of this Agreement are required to be performed by the Lenders.

125

(d) The Borrowers agree that each Lender may without notice to or the consent of the Borrowers, the Administrative Agent, any Fronting Bank or the Swingline Lender sell participations to one or more banks or other entities in all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment and the same portion of the Revolving Loans owing to it) and the Borrowers agree that any purchaser of a participation in such Loans so acquired may exercise any and all rights of bankers lien, setoff, counterclaim or otherwise with respect to any and all moneys owing by the Borrowers to such purchaser as fully as if such purchaser were a Lender acquiring such Loans hereunder in the amount of such participation so long as the Borrower is notified of the participants participation hereunder and such participant complies with Section 10.08 as if it were a Lender prior to such exercise; provided, however, that (xii) such selling Lenders obligations under this Agreement shall remain unchanged, (xiii) such Lender shall remain solely responsible to the Borrowers for the performance of its obligations hereunder, (xiv) the participating lenders or other entities shall be entitled to the benefit of the cost protection provisions contained in Sections 2.14, 2.16 and 2.19 to the same extent as if they were such Lender (but the amount claimed by any participating lender or other entity shall not exceed the amount that could have been claimed by the Lender from which it acquired its participation) and (xv) the Borrowers, the Agents, the Fronting Banks and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lenders rights and obligations under this Agreement, and such Lender shall retain the sole right to enforce the obligations of the Borrowers relating to the Loans and to approve, without the consent of or consultation with any participant, any amendment, modification or waiver of any provision of this Agreement (other than amendments, modifications or waivers with respect to Fees payable hereunder or an increase in the amount of principal of or a decrease in the rate at which interest is payable on the Loans, or an extension of the dates fixed for payments of principal of or interest on the Loans or payments of Fees). Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters the name and address of each participant and the amounts of each participants participation (the Participant Register). The entries in the Participant Register shall be conclusive, absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.

126

(e) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 10.07, disclose to the assignee or participant or proposed assignee or participant any information relating to Lyondell and its Subsidiaries furnished to the Lenders (including pursuant to Section 5.08) by or on behalf of Lyondell and its Subsidiaries, as applicable; provided that, prior to any such disclosure, each such assignee or participant or proposed assignee or participant shall execute an agreement whereby such assignee or participant shall agree (subject to customary exceptions) to preserve the confidentiality of any confidential information relating to Lyondell and its any Subsidiary received from the Agents or Lenders.

(f) The Administrative Agent, acting solely for this purpose as an agent of the Borrowers, shall maintain at one of its offices in The City of New York a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders and the Commitment (if any) of, and the principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof (the Register), and no such Assignment and Acceptance shall be effective until so recorded. The entries in the Register shall be conclusive in the absence of manifest error and the Borrowers, the Agents, the Fronting Banks and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrowers at any reasonable time and from time to time upon reasonable prior notice. Upon its receipt of an executed Assignment and Acceptance, together with any Note subject to such assignment, and the payment of any processing and registration fee, the Administrative Agent shall (xvi) accept such Assignment and Acceptance, (xvii) record the information contained therein in the Register and (xviii) give prompt notice thereof to the parties thereto.

(g) Any Lender may at any time pledge all or any portion of its rights under the Loan Documents to secure obligations of such Lender, without the consent of any party, without notice to any party and without payment of fees, in accordance with applicable law, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge shall release any Lender from its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

127

(h) Notwithstanding anything to the contrary contained herein, any Lender (a Granting Bank) may grant to a special purpose funding vehicle (an SPC) of such Granting Bank, identified as such in writing from time to time by the Granting Bank to the Administrative Agent and the Borrowers, the option to provide to the Borrowers all or any part of any Loan that such Granting Bank would otherwise be obligated to make to the Borrowers pursuant to Section 2.02, provided that (xix) nothing herein shall constitute a commitment to make any Loan by any SPC and (xx) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Bank shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall be deemed to utilize the Commitments of all the Lenders to the same extent, and as if, such Loan were made by the Granting Bank. Each party hereto hereby agrees that no SPC shall be liable for any payment under this Agreement for which a Lender would otherwise be liable, for so long as, and to the extent, the related Granting Bank makes such payment. In furtherance of the foregoing, each party hereto hereby agrees that, prior to the date that is one (1) year and one (1) 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 10.07, any SPC may assign all or a portion of its interests in any Loans to its Granting Bank or to any financial institutions providing liquidity and/or credit facilities to or for the account of such SPC to fund the Loans made by such SPC or to support the securities (if any) issued by such SPC to fund such Loans; provided, however, that except in the case of an assignment to a Granting Bank or a financial institution that is either an affiliate of such SPC or another Lender, the Administrative Agent and, unless an Event of Default has occurred and is continuing, the Borrowers 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 Borrowers and their Affiliates received from the Agents or Lenders.

Section 10.08. Right of Setoff. (d) Upon the occurrence and during the continuation of any Event of Default each Lender is hereby authorized, in addition to any other right or remedy that any Lender may have by operation of law or otherwise, at any time and from time to time, without notice to the Borrowers except to the extent required by applicable law (any such notice being expressly waived by the Borrowers to the maximum extent possible under applicable law), and subject to any requirements or limitations imposed by applicable law, to exercise its bankers lien or right of setoff 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 Lender or any of its Affiliates to or for the credit or the account of any Borrower against any and all the obligations of the Borrowers now or hereafter existing under any Loan Document, irrespective of whether or not such Lender or any of its Affiliates shall have made any demand under such Loan Agreement and although such obligations may be unmatured.

(b) Each Lender agrees promptly to notify the Administrative Agent and the Borrowers after any such setoff and application; provided, however, that, to the extent permitted by applicable law, the failure to give any such notice shall not affect the validity of such setoff and application.

128

Section 10.09. Severability. In case any one or more of the provisions contained in the Loan Documents shall be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained therein shall not in any way be affected or impaired thereby. The parties shall endeavor in good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

Section 10.10. Cover Page, Table of Contents and Section Headings. The cover page, Table of Contents and Section headings used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of or be taken into consideration in interpreting this Agreement.

Section 10.11. Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts with the same effect as if the signatures thereon and hereon were upon the same instrument. Delivery by telecopier, PDF or other electronic means of an executed counterpart of a signature page to this Agreement shall be effective as delivery of an original executed counterpart of this Agreement. This Agreement shall become effective when copies hereof which, when taken together, bear the signatures of each of the parties hereto shall have been received by the Administrative Agent.

Section 10.12. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THE LOAN DOCUMENTS. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION

Section 10.13. Entire Agreement. This Agreement, the Collateral Documents, the agreements referred to in Section 2.07 and any promissory notes delivered pursuant hereto constitute the entire contract between the parties relative to the subject matter hereof. Any previous agreement among the parties with respect to the subject matter hereof is superseded by the Loan Documents and such letter agreements, except to the extent expressly provided therein. Nothing in the Loan Documents or such letter agreements or promissory notes, expressed or implied, is intended to confer upon any party other than the parties hereto and thereto and Indemnitees referred to in Section 10.05(b) any rights, remedies, obligations or liabilities under or by reason of the Loan Documents or such letter agreements or promissory notes.

129

Section 10.14. Confidentiality. Each of the Agents, each Fronting Bank, the Lenders and the SPCs (as defined in Section 10.07(h)) agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (e) 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), (f) to the extent required or requested by any regulatory authority, (g) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (h) to any other party to this Agreement, (i) in connection with the exercise of any remedies under any Loan Document or any suit, action or proceeding relating to any Loan Document or the enforcement of rights thereunder, (j) 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 10.07(h)), (k) with the consent of the Borrowers, (l) for purposes of Section 10.07(h) only, to any rating agency, (m) 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 any Fronting Bank or any Agent or Lender on a nonconfidential basis from a source other than the Borrowers or (n) to any direct or indirect contractual counterparty in any swap, hedge or similar agreement (or to such contractual counterpartys 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 Borrowers relating to the Borrowers and their Affiliates or their respective businesses, other than any such information that is available to any Fronting Bank or any Agent or Lender on a nonconfidential basis prior to disclosure by the Borrowers. 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 anything herein to the contrary, Information shall not include, and each party hereto may disclose 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 hereby and all materials of any kind (including opinions or other tax analyses) that are provided to such party relating to such tax treatment and tax structure.

Section 10.15. Lender Action. Each Lender agrees that it shall not take or institute any actions or proceedings, judicial or otherwise, for any right or remedy against any Loan Party or any other obligor under any of the Loan Documents (including the exercise of any right of setoff, rights on account of any bankers lien or similar claim or other rights of self-help), or institute any actions or proceedings, or otherwise commence any remedial procedures, with respect to any Collateral or any other property of any such Loan Party, without the prior written consent of the Administrative Agent. The provision of this Section 10.15 are for the sole benefit of the Lenders and shall not afford any right to, or constitute a defense available to, any Loan Party.
