“Consents” shall mean all filings and all licenses, permits, consents, approvals, authorizations, qualifications and orders of Governmental Bodies and other third parties, domestic or foreign, necessary to carry on any Borrower’s business or necessary (including to avoid a conflict or breach under any agreement, instrument, other document, license, permit or other authorization) for the execution, delivery or performance of this Agreement or the Other Documents, including any Consents required under all applicable federal, state or other Applicable Law. “Contract Rate” shall mean an interest rate equal to the sum of the Applicable Margin plus the Daily LIBOR Rate, and the rate of interest charged to Borrowers hereunder will be adjusted automatically as of each Business Day based on any applicable changes to either the Published Rate for such Business Day or the Reserve Percentage for such Business Day without notice to the Borrower; provided that: (a) If Agent or any Lender determines (which determination shall be final and conclusive) that, (a) reasonable means do not exist for ascertaining the Daily LIBOR Rate; (b) Dollar deposits in the relevant amount and for the relevant maturity for the determination of the Daily LIBOR Rate are not available in the London interbank eurodollar market, (c) the making, maintenance or funding of any Advance with interest accruing thereon at the Daily LIBOR Rate has been made impracticable or unlawful by compliance by Agent or such Lender in good faith with any Applicable Law or any interpretation or application thereof by any Governmental Body or with any request or directive of any such Governmental Body (whether or not having the force of law), or (d) the Daily LIBOR Rate will not adequately and fairly reflect the cost to such Lender of the establishment or maintenance of any Advance, then Agent shall give prompt written or telephonic notice to Borrowers and Lenders of such determination. Then thereafter, until Agent notifies Borrowers that the circumstances giving rise to such suspension no longer exist (but subject to the provisions of Section 3.7 hereof), the Contract Rate shall be equal to (A) the Alternate Base Rate plus (B) 1.50%. “Alternate Base Rate” shall mean, for any day, a rate per annum equal to the highest of (a) the Prime Rate in effect on such day or (b) the sum of the Overnight Bank Funding Rate in effect on such day plus one half of one percent (0.5%).

change. If the Overnight Bank Funding Rate determined as above would be less than zero, then such rate shall be deemed to be zero. “Prime Rate” shall mean the rate publicly announced by Agent from time to time as its prime rate, and at any time when the Contract Rate is computed based on the Alternate Base Rate, the rate of interest charged shall be adjusted as of each Business Day based on changes in the Prime Rate without notice to the Borrower, effective on the date of any such change. The Prime Rate is determined from time to time by Agent as a means of pricing some loans to its borrowers. The Prime Rate is not tied to any external rate of interest or index, and does not necessarily reflect the lowest rate of interest actually charged by Agent to any particular class or category of customers; and (ii) In addition, if, after the Closing Date, if any Lender shall reasonably determine (which determination shall be final and conclusive) that any Change in Law, or compliance by such Lender with any guideline, request or directive (whether or not having the force of law) of any Governmental Body, shall make it unlawful or impossible for such to make or maintain or fund loans based on the Daily LIBOR Rate, the Agent shall notify the Borrowers in writing of such determination. Upon receipt of such notice, until Agent notifies Borrower that such Lender has notified Agent that the circumstances giving rise to such determination no longer apply, Contract Rate shall be equal to (A) the Alternate Base Rate plus (B) 1.50%. “Contractual Obligation” shall mean, as to any Person, any provision of any security issued by such Person or of any agreement, instrument or other undertaking to which such Person is a party or by which it or any of its property is bound. “Controlled Collection Accounts” shall have the meaning set forth in Section 4.5(h) hereof. “Connection Income Taxes” means Other Connection Taxes that are imposed on or measured by net income (however denominated) or that are franchise Taxes or branch profits Taxes. “Covered Entity” shall mean (a) each Borrower, each of each Borrower’s Subsidiaries and all pledgors of Collateral and (b) each Person that, directly or indirectly, is in control of a Person described in clause (a) above. For purposes of this definition, control of a Person shall mean the direct or indirect (x) ownership of, or power to vote, 25% or more of the issued and outstanding Equity Interests having ordinary voting power for the election of directors of such Person or other Persons performing similar functions for such Person, or (y) power to direct or cause the direction of the management and policies of such Person whether by ownership of Equity Interests, contract or otherwise. “Daily LIBOR Rate” shall mean, for any day, the rate per annum determined by Agent by dividing (x) the Published Rate by (y) a number equal to 1.00 minus the Reserve Percentage; provided, however, that if the Daily LIBOR Rate determined as provided above would be less than 1.00%, such rate shall be deemed to be 1.00% for purposes of this Agreement. Each determination of the Daily LIBOR Rate shall be made by Agent and shall be conclusive in the absence of manifest error. “Debarment Regulations” shall mean, collectively, (a) the Governmentwide Debarment and Suspension (Nonprocurement) regulations (Common Rule), 53 Fed.

Agent shall conditionally credit Borrowers’ Account for each item of payment (i) if received by Agent on or prior to 2:00 p.m. on a Business Day, on such Business Day and (ii) if received by Agent after 2:00 p.m. on a Business Day, or on a day which is not a Business Day, on the next Business Day after the day on which such item of payment is received by Agent (and the Business Day on which each such item of payment is so credited shall be referred to, with respect to such item, as the “Application Date”). Agent is not, however, required to credit Borrowers’ Account for the amount of any item of payment which is not reasonably satisfactory to Agent and Agent may charge Borrowers’ Account for the amount of any item of payment which is returned, for any reason whatsoever, to Agent unpaid.

The monthly statements shall be deemed correct and binding upon Borrowers in the absence of manifest error and shall constitute an account stated between Lenders and Borrowers unless Agent receives a written statement of Borrowers’ specific exceptions thereto within thirty (30) days after such statement is received by Borrowing Agent. The records of Agent with respect to Borrowers’ Account shall be conclusive evidence absent manifest error of the amounts of Advances and other charges thereto and of payments applicable thereto. 2.6.

Each such notice shall specify the date and amount of such prepayment and the Transaction Specific Loans to be prepaid. Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s applicable pro rata share of such prepayment. The Borrowers may revoke, rescind or extend a prepayment notice relative to proposed payment in full of the Transaction Specific Loans with the proceeds of third party Indebtedness or other transactions if the closing for such issuance or incurrence or other transactions does not happen on the date of the proposed termination. Unless all Term Lenders shall agree otherwise in any particular case (which establishing any course of dealing or course of conduct for any such voluntary prepayment of the Transaction Specific Loans made thereafter), such any voluntary prepayment shall be accompanied by all accrued interest on the amount prepaid. 26

(b) Mandatory Prepayments. (i) When any proceeds of any Collateral are received by any Borrower (including but not limited to any such receipt by direct remittance of such proceeds by the applicable Specified Export Order Buyer into the Controlled Collections Account in accordance with Section 4.5(h) hereof), Borrowers shall prepay the Advances in an amount equal to 100% of such proceeds, such prepayment to be due and payable (x) in the case of any such proceeds received by direct remittance of such proceeds by the applicable Specified Export Order Buyer into the Controlled Collections Account, on the date of the remittance thereof to the Controlled Collections Account (subject to the provisions of Sections 2.4 and 4.5(h)), and (y) in the case of any such proceeds received directly by any Borrower (notwithstanding the provisions of Section 4.5(a)), no later than five (5) Business Days following an officer of the applicable Borrower obtaining knowledge of such Borrower’s receipt of such proceeds, and until the date of payment, such proceeds shall be held in trust for Secured Parties; (ii) When any Borrower sells or otherwise Disposes of any Collateral, Borrowers shall prepay the Advances in an amount equal to the Net Cash Proceeds of such event, such prepayment to be due and payable no later than ten (10) Business Days following an officer of the applicable Borrower obtaining knowledge of such Borrower’s following receipt of such Net Cash Proceeds, and until the date of payment, such proceeds shall be held in trust for Secured Parties (the foregoing shall not be deemed to be implied consent to any such sale otherwise prohibited by the terms and conditions hereof). (c) Subject to the provisions of Section 11.5 hereof, voluntary and mandatory prepayments paid pursuant to this Section 2.6 shall be applied, ratably among the Lenders, to the then-outstanding principal of the Transaction Specific Loans until paid in full 2.7.

Amounts received in respect of principal of any type of Advances shall be applied to reduce such type of Advances of each Lender (other than any Defaulting Lender) in accordance with their Commitment Percentages; provided, that, Agent shall not be obligated to transfer to a Defaulting Lender any payments received by Agent for Defaulting Lender’s benefit, nor shall a Defaulting Lender be entitled to the sharing of any payments hereunder (including any principal, interest or fees). Amounts payable to a Defaulting Lender shall instead be paid to or retained by Agent. Agent may hold the amount of such payments received or retained by it for the account of such Defaulting Lender. (b) A Defaulting Lender shall not be entitled to give instructions to Agent or to approve, disapprove, consent to or vote on any matters relating to this Agreement and the Other Documents, and all amendments, waivers and other modifications of this Agreement and the Other Documents may be made without regard to a Defaulting Lender and, for purposes of the definition of Required Lenders, a Defaulting Lender shall not be deemed to be a Lender, to have any outstanding Advances or a Commitment or any Commitment, provided, that this clause (c) shall not apply to the vote of a Defaulting Lender in the case of an amendment, waiver or other modification described in clauses (i) or (ii) of Section 16.2(b) hereof. 28

(c) Other than as expressly set forth in this Section 2.8, the rights and obligations of a Defaulting Lender (including the obligation to indemnify Agent) and the other parties hereto shall remain unchanged. Nothing in this Section 2.8 shall be deemed to release any Defaulting Lender from its obligations under this Agreement and the Other Documents, shall alter such obligations, shall operate as a waiver of any default by such Defaulting Lender hereunder, or shall prejudice any rights which any Borrower, Agent or any Lender may have against any Defaulting Lender as a result of any default by such Defaulting Lender hereunder. (d) In the event that Agent and Borrowers agree in writing that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then Agent will so notify the parties hereto. 2.9. Additional Obligations. All (i) amounts expended by Agent or any Lender pursuant to Sections 4.2 or 4.3 hereof, (ii) expenses which Agent incurs in connection with the forwarding of Advance proceeds and the establishment and maintenance of the Controlled Collection Accounts, and (iii) sums expended by Agent or any Lender due to any Borrower’s failure to perform or comply with its obligations under this Agreement or any Other Document including any Borrower’s obligations under Section 4.4 hereof, shall, in each case, be added to the Obligations and shall be secured by the Collateral. III. INTEREST AND FEES. 3.1. Interest. Interest on Advances shall be payable in arrears within three (3) Business Days after the Borrowing Agent’s receipt of each Monthly Statement, provided that all accrued and unpaid interest shall be due and payable at the end of the Term. Interest charges shall be computed on the actual principal amount of Advances outstanding for each day during the month in this Agreement, any Obligations other than the Advances that are not paid when due shall accrue interest at the Contract Rate, subject to the provision of the final sentence of this Section 3.1 regarding the Default Rate. Any overdue principal of, or overdue interest on, any Advance shall, at the option of Agent or at the direction of Required Lenders (or, in the case of any failure to pay upon any acceleration of the Obligations following an Event of Default under Section 10.5, immediately and automatically without the requirement of any affirmative action of any Person), bear interest, payable on demand, at a rate per annum equal to the applicable Contract Rate plus two percent (2%) (as applicable, the “Default Rate”). 3.2. [RESERVED]. 3.3. Fee Letter. Borrowers shall pay the amounts required to be paid in the Fee Letter to the applicable parties, in the manner, in the applicable amounts and as and when due as provided for in the Fee Letter. 3.4. Computation of Interest and Fees. Interest and fees hereunder shall be computed on the basis of a year of 360 days and for the actual number of days elapsed; provided that if any such interest or fees are determined at any time by reference to the Alternate Base Rate, such interest or fees shall be computed on the basis of a year of 365 days. If any payment to be made hereunder becomes due and payable on a day other than a Business Day, the due date thereof shall be extended to the next succeeding Business Day and interest thereon shall be payable at the applicable Contract Rate during such extension. 29

3.5. Maximum Charges. In no event whatsoever shall interest and other charges charged hereunder exceed the highest rate permissible under Applicable Law. In the event interest and other charges as computed hereunder would otherwise exceed the highest rate permitted under Applicable Law: (i) the interest rates hereunder will be reduced to the maximum rate permitted under Applicable Law; (ii) such excess amount shall be first applied to any unpaid principal balance owed by Borrowers; and (iii) if the then remaining excess amount is greater than the previously unpaid principal balance, Lenders shall promptly refund such excess amount to Borrowers and the provisions hereof shall be deemed amended to provide for such permissible rate. 3.6. Increased Costs. In the event that any Change in Law (for purposes of this Section 3.6, the term “Lender” shall include Agent, any Lender, and bank holding company Controlling Agent or such Lender) shall: (a) subject Agent or any Lender to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) with respect to its Commitments or Advances, loan principal, or other Obligations, or its deposits, reserves, other liabilities or capital or liquidity attributable thereto; (b) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets held by, or deposits with or for the account of other credit extended by, any Lender (except any such reserve requirement reflected in the Reserve Percentage; or (c) impose on Agent or any Lender, or the London interbank market, any other condition (other than Taxes) affecting this Agreement or any Other Document or any Advance based on the Daily LIBOR Rate made by any Lender; and the result of any of the foregoing is to increase the cost to Agent or any Lender of making, or maintaining its Advances based on the Daily LIBOR Rate (or of maintaining its obligation to make Advances based on the Daily LIBOR Rate) or to reduce any amount received or receivable by Agent or such Lender hereunder (whether of principal, interest or otherwise), in each case, by an amount deemed by Agent or such Lender to be material, then Borrowers shall promptly pay to Agent or such Lender, upon its demand, such additional amount as will compensate Agent or such Lender for such additional cost incurred or such reduction suffered. Together with any such demand, such Lender shall certify the amount of such additional cost or reduced amount to Borrowing Agent (and such demand and certification shall be delivered not later than 180 calendar days following the applicable Change in Law), and such certification shall be conclusive absent manifest error. 3.7. Alternate Rate of Interest. (a) Benchmark Replacement. Notwithstanding anything to the contrary herein or in the Other Documents, if Agent determines that a Benchmark Transition Event or an Early Opt-in Event has occurred, Agent and Borrowers may amend this Agreement to replace the Daily LIBOR Rate with a Benchmark Replacement; and any such amendment will become effective at 5:00 p.m. on the fifth (5th) Business Day after Agent has provided such proposed amendment to all Lenders, so long as the Agent has not received, by such time, written notice of objection to such amendment from Lenders comprising the Required Lenders. Until the Benchmark Replacement 30

is effective, subject to the provisions of the definition of Contract Rate, each Advance will continue to bear interest with reference to the LIBOR Rate. (b) Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in the Other Documents, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement. (c) Notices; Standards for Decisions and Determinations. Agent will promptly notify Borrowers and Lenders of (i) the implementation of any Benchmark Replacement, (ii) the effectiveness of any Benchmark Replacement Conforming Changes and (iii) the commencement of any Benchmark Unavailability Period. Any determination, decision or election that may be made by Agent or Lenders pursuant to this Section 3.7 including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party hereto, except, in each case, as expressly required pursuant to this Section 3.7 (d) Certain Defined Terms. As used in this Section 3.7: “Benchmark Replacement” means the sum of: (a) the alternate benchmark rate that has been selected by the Agent and the Borrower giving due consideration to (i) any selection or recommendation of a replacement rate or the mechanism for determining such a rate by the Relevant Governmental Body or (ii) any evolving or then-prevailing market convention for determining a rate of interest as a replacement to interest rates based on the LIBOR Rate for U.S. dollar-denominated credit facilities and (b) the Benchmark Replacement Adjustment; provided that, if the Benchmark Replacement as so determined would be less than 1.00%, the Benchmark Replacement will be deemed to be 1.00% for the purposes of this Agreement. “Benchmark Replacement Adjustment” means, with respect to any replacement of the Daily LIBOR Rate with an alternate benchmark rate, the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected by Agent and Borrowers (a) giving due consideration to (i) any selection or recommendation of a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the Daily LIBOR Rate with the applicable Benchmark Replacement (excluding such spread adjustment) by the Relevant Governmental Body or (ii) any evolving or then-prevailing market convention for determining a spread adjustment, or method for calculating or determining such spread adjustment, for such replacement of interest rates based on the LIBOR Rate for U.S. dollar denominated credit facilities at such time and (b) which may also reflect adjustments to account for (i) the effects of the transition from the Daily LIBOR Rate to the Benchmark Replacement and (ii) yield- or risk-based differences between the Daily LIBOR Rate and the Benchmark Replacement. “Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the timing and frequency of determining rates and making payments of interest and other 31

administrative matters) that Agent decides may be appropriate to reflect the adoption and implementation of such Benchmark Replacement and to permit the administration thereof by Agent in a manner substantially consistent with market practice (or, if Agent decides that adoption of any portion of such market practice is not administratively feasible or if Agent determines that no market practice for the administration of the Benchmark Replacement exists, in such other manner of administration as Agent decides is reasonably necessary in connection with the administration of this Agreement). “Benchmark Replacement Date” means the earlier to occur of the following events with respect to the LIBOR Rate: (1) in the case of clause (1) or (2) of the definition of Benchmark Transition Event, the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the LIBOR Rate permanently or indefinitely ceases to provide the LIBOR Rate; or (2) in the case of clause (3) of the definition of Benchmark Transition Event, the date of the public statement or publication of information referenced therein. “Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the LIBOR Rate (1) a public statement or publication of information by or on behalf of the administrator of the LIBOR Rate announcing that such administrator has ceased or will cease to provide the LIBOR Rate, permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the LIBOR Rate; (2) a public statement or publication of information by a Governmental Body having jurisdiction over Agent, the regulatory supervisor for the administrator of the LIBOR Rate, the U.S. Federal Reserve System, an insolvency official with jurisdiction over the administrator for the LIBOR Rate, a resolution authority with jurisdiction over the administrator for the LIBOR Rate or a court or an entity with similar insolvency or resolution authority over the administrator for the LIBOR Rate, which states that the administrator of the LIBOR Rate has ceased or will cease to provide the LIBOR Rate permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the LIBOR Rate; or (3) a public statement or publication of information by the regulatory supervisor for the administrator of the LIBOR Rate or a Governmental Body having jurisdiction over Agent announcing that the LIBOR Rate is no longer representative. “Benchmark Unavailability Period” means, if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the LIBOR Rate and solely to the extent that the Daily LIBOR Rate has not been replaced with a Benchmark Replacement, the period (x) beginning at the time that such Benchmark Replacement Date has occurred if, at such time, no Benchmark Replacement has replaced the Daily LIBOR Rate for all purposes hereunder in accordance with Section 3.7 and (y) ending at the time that a Benchmark Replacement has replaced the Daily LIBOR Rate for all purposes hereunder pursuant to Section 3.7. 32

“Early Opt-in Event” means a determination by Agent that U.S. dollar denominated credit facilities being executed at such time, or that include language similar to that contained in this Section 3.7, are being executed or amended, as applicable, to incorporate or adopt a new benchmark interest rate to replace LIBOR Rate for interest rates based on the LIBOR Rate. “Relevant Governmental Body” means the Federal Reserve Board and/or the Federal Reserve Bank of New York, or a committee officially endorsed or convened by the Federal Reserve Board and/or the Federal Reserve Bank of New York or any successor thereto. 3.8. Capital Adequacy. (a) In the event that any Lender shall have determined that any Change in Law regarding capital requirements or liquidity requirements or compliance by Agent or any Lender therewith (for purposes of this Section 3.8, the term “Lender” shall include Agent or any Lender and any bank holding company Controlling Agent or such Lender) has or would have the effect of reducing the rate of return on such Lender’s capital as a consequence of this Agreement or the Advances made by such Lender to a level below that which Agent or such Lender could have achieved but for such Change in Law (taking into consideration such Lender’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then, from time to time, Borrowers shall pay within 10 days of a demand (which demand must be made within 180 days of the applicable Change in Law) to such Lender such additional amount or amounts as will compensate such Lender for such reduction suffered . (b) A certificate of such Lender setting forth such amount or amounts as shall be necessary to compensate such Lender with respect to Section 3.8(a) hereof shall be delivered to Borrowing Agent concurrently with any such demand and shall be conclusive absent manifest error. Each such certificate shall contain a representation and warranty on the part of such Lender to the effect that such Lender has complied with its obligations pursuant to Section 3.10(a) in an effort to eliminate or reduce such amount. 3.9. Taxes. (a) Any and all payments by or on account of any Obligations hereunder or under any Other Document shall be made free and clear of and without reduction or withholding for any Taxes, except as required by Applicable Law. If any Applicable Law (as determined in the good faith discretion of an applicable withholding agent) requires the deduction or withholding of any Tax from any such payment by a withholding agent, then the applicable withholding agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Body in accordance with Applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 3.9) Agent or the applicable Lender receives an amount equal to the sum it would have received had no such deduction or withholding been made. For purposes of this Section 3.9, the term “Applicable Law” shall include, without limitation, FATCA. 33

(b) Without limiting the provisions of Section 3.9(a) above, Borrowers shall timely pay to the relevant Governmental Body in accordance with Applicable Law, or at the option of the Agent, timely reimburse the Agent for the payment of, Other Taxes. (c) (i) Each Borrower shall indemnify Agent and each Lender, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 3.9) paid by Agent or such Lender, as the case may be, or required to be withheld or deducted from a payment to Agent or such Lender and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Body. A certificate as to the amount of such payment or liability delivered to Borrowers by any Lender (with a copy to Agent), or by Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. (ii) Each Lender shall severally indemnify Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 16.3(b) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by Agent in connection with this Agreement or any Other Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Body. A certificate as to the amount of such payment or liability delivered to any Lender by Agent shall be conclusive absent manifest error. Each Lender hereby authorizes Agent to set off and apply any and all amounts at any time owing to such Lender under this Agreement or any Other Document or otherwise payable by Agent to the Lender from any other source against any amount due to the Agent under this Section 3.9(c)(ii). (d) As soon as practicable after any payment of Taxes by any Borrower to a Governmental Body pursuant to this Section 3.9, Borrowers shall deliver to Agent the original or a certified copy of a receipt issued by such Governmental Body, if it exists, evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to Agent. (e) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments hereunder or under any Other Document shall deliver to Borrowers and Agent, at the time or times prescribed by Applicable Law or reasonably requested by Borrowers or Agent, such properly completed and executed documentation or reasonably requested by Borrowers or Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by Borrowers or Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by Borrowers or Agent as will enable Borrowers or Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in 34

paragraphs (e)(i), (ii), (iii), (v) and (f) of this Section 3.9) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. Without limiting the generality of the foregoing, each Lender shall deliver to Borrowers and Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of Borrowers or Agent), whichever of the following is applicable: (i) two (2) duly completed valid copies of IRS Form W-8BEN or W- 8BEN-E claiming eligibility for benefits of an income tax treaty to which the United States of America is a party, (ii) two (2) duly completed valid copies of IRS Form W-8ECI, (iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of Borrowers within the meaning of Section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code and (y) two duly completed valid copies of IRS Form W-8BEN or W-8BEN-E, (iv) any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by Applicable Law to permit Borrowers to determine the withholding or deduction required to be made, or (v) to the extent that any Lender is not a Foreign Lender, such Lender shall submit to Agent two (2) copies of an IRS Form W-9 or any other form prescribed by Applicable Law demonstrating that such Lender is not a Foreign Lender. (f) If a payment made to any Lender under this Agreement or any Other Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to Agent and Borrowers at the time or times prescribed by Applicable Law and at such time or times reasonably requested by Borrowers or Agent such documentation prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by Agent or any Borrower as may be necessary for Agent and Borrowers to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount, if any, to deduct and withhold from such payment. Solely for purposes of this clause (f), “FATCA” shall include any amendments made to FATCA after the Closing Date. (g) If Agent or any Lender determines, in its sole discretion, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 3.9 (including the payment of additional amounts pursuant to this Section 3.9), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 3.9 with respect to Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by 35

the relevant Governmental Body with respect to such refund), provided that such indemnifying party, upon the request of such indemnified party, agrees to repay the amount paid over to such indemnified party pursuant to this clause (g) (plus any penalties, interest or other charges imposed by the relevant Governmental Body) if such indemnified party is required to repay such refund to such Governmental Body. Notwithstanding anything to the contrary in this clause (g), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this clause (g) the payment of which would place the indemnified party in a less favorable net after- Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require Agent or any Lender to make available its tax returns (or any other information relating to its taxes that it deems confidential) to Borrowers or any other Person. (h) Each Lender agrees that if any form or certification it previously delivered expired or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower or Agent in writing of its legal inability to do so. Each party’s obligations under this Section 3.9 shall survive the resignation or replacement of the Agent or any assignment of rights by, or replacement of, a Lender, the termination of the Commitments and Payment in Full of the Obligations. 3.10. Lender’s Obligation to Mitigate; Replacement of Lenders. (a) If any Lender (an “Affected Lender”) makes demand upon Borrowers for (or if Borrowers are otherwise required to pay) amounts pursuant to Section 3.6, 3.8 or 3.9 hereof, then such Lender shall use all commercially reasonable efforts to mitigate or eliminate the amount of such compensation or additional amount, including by designating a different lending office for funding or booking its Advances hereunder or by assigning its rights and obligations hereunder to another of its offices, branches or Affiliates; provided that no Lender shall be required to take any action under this Section 3.10(a) unless, in the judgment of such Lender, such designation or assignment or other action would (i) eliminate or reduce amounts payable pursuant to Section 3.6, 3.8 or 3.9, as the case may be, in the future, (ii) would not subject such Lender to any unreimbursed cost or expense or (iii) would not otherwise be disadvantageous to such Lender. Borrowers shall pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. (b) If any Lender (a) is an Affected Lender, (b) is a Defaulting Lender, or (c) denies any consent requested pursuant to Section 16.2(b) hereof (each such Lender, a “Subject Lender”), Borrowers may, by notice (a “Replacement Notice”) in writing to Agent and such Subject Lender (i) request the Subject Lender to cooperate with Borrowers in obtaining a replacement Lender satisfactory to Agent and Borrowers (the “Replacement Lender”); (ii) request the non- Subject Lenders to acquire and assume all of the Affected Lender’s Advances and to the extent any portion thereof remains unterminated, unexpired, and unfunded its Commitment, all as provided herein, but none of such Lenders shall be under any obligation to do so; or (iii) propose a Replacement Lender subject to approval by Agent in their good faith business judgment. If any satisfactory Replacement Lender shall be obtained, and/or if any one or more of the non- Subject Lender(s) shall agree to acquire and assume all of the Subject Lender’s Advances and, to the extent any portion thereof remains unterminated, unexpired and unfunded its Commitment, then such 36

Subject Lender shall assign, in accordance with Section 16.3 hereof, all of its Advances and, if and as applicable, its Commitment and/or, to the extent any portion thereof remains unterminated, unexpired and unfunded its Commitment portion thereof remains unterminated, unexpired and unfunded, its Commitment, and, and other rights and obligations under this Agreement and the Other Documents to such Replacement Lender or non-Subject Lender(s), as the case may be, in exchange for payment of the principal amount so assigned and all interest and fees accrued on the amount so assigned, plus all other Obligations then due and payable to the Subject Lender, as applicable, assigned, plus all other Obligations then due and payable to the Affected Lender, as applicable. Such assignment may be effected pursuant to a Commitment Transfer Supplement executed by the Agent, the Replacement Lender or non- Subject Lender(s), as applicable, and the Borrower, and the applicable Subject Lender need not be party thereto in order for such assignment to be effective and shall be deemed to have consented to and be bound by the terms thereof. IV. COLLATERAL: GENERAL TERMS 4.1. Security Interest in the Collateral. To secure the prompt payment and performance to Agent and each other Secured Party of the Obligations, each Borrower hereby assigns, pledges and grants to Agent for its benefit and for the ratable benefit of each other Secured Party, a continuing security interest in and to and Lien on all of its Collateral, whether now owned or existing or hereafter created, acquired or arising and wheresoever located. Each Borrower shall xxxx its books and records as may be necessary or appropriate to evidence, protect, and perfect Agent’s security interest and shall cause its financial statements to reflect such security interest. 4.2. Perfection of Security Interest. Each Borrower shall take all action that may be necessary or desirable, or that Agent may reasonably request, so as at all times to maintain the validity, perfection, enforceability and priority of Agent’s security interest in and Lien on the Collateral or to enable Agent to protect, exercise or enforce its rights hereunder and in the Collateral, including, but not limited to, (a) immediately discharging all Liens on the Collateral other than Permitted Encumbrances, (b) delivering to Agent, endorsed or accompanied by such instruments of assignment as Agent may specify, and stamping or marking, in such manner as Agent may specify, any and all chattel paper, instruments, letters of credit and advices thereof evidencing or forming a part of the Collateral, and (c) executing and delivering financing statements, Control Agreements, instruments of pledge, notices and assignments, in each case in form and substance reasonably satisfactory to Agent, relating to the creation, validity, perfection, maintenance, or continuation of Agent’s security interest and Lien under the Uniform Commercial Code or other Applicable Law .

Subject to the foregoing, Agent may enter any of any Borrower’s premises or other premises without legal process and without incurring liability to any Borrower therefor, and Agent may thereupon, or at any time thereafter, in its discretion without notice or demand, take the Collateral and remove the same to such place as Agent may deem advisable and Agent may require Borrowers to make the Collateral available to Agent at a convenient place. With or without having the Collateral at the time or place of sale, Agent may sell the Collateral, or any part thereof, at public or private sale, at any time or place, in one or more sales, at such price or prices, and upon such terms, either for cash, credit or future delivery, as Agent may elect. Except as to that part of the Collateral which is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, Agent shall give Borrowers reasonable notification of such sale or sales, it being agreed that in all events written notice mailed to Borrowing Agent at least ten (10) Business Days prior to such sale or sales is reasonable notification. At any public sale Agent or any Lender may bid (including credit bid) for and become the purchaser, and Agent, any Lender or any other purchaser at any such sale thereafter shall hold the Collateral sold absolutely free from any claim or right of whatsoever kind, including any equity of redemption and all such claims, rights and equities are hereby expressly waived and released by each Borrower. In connection with the exercise of the foregoing remedies, including the sale of Inventory, upon the occurrence and during the continuance of an Event of Default, Agent is granted a perpetual non-revocable, royalty free, nonexclusive license and Agent is granted permission to use all of each Borrower’s (a) Intellectual Property which is used or useful in connection with Inventory for the purpose of marketing, advertising for sale and selling or otherwise disposing of such Inventory (but not any other Intellectual Property of any Borrower) and (b) equipment for the purpose of completing the manufacture of unfinished goods (but not any other equipment of any Borrower). The Net Cash Proceeds realized from the sale of any Collateral shall be applied to the Obligations in the order set forth in Section 11.5 hereof. Non-cash proceeds will only be applied to the Obligations as they are converted into cash. If any deficiency shall arise, Borrowers shall remain liable to Agent and Lenders therefor. (b) To the extent that Applicable Law imposes duties on Agent to exercise remedies in a commercially reasonable manner, each Borrower acknowledges and agrees that it is not commercially unreasonable for Agent: (i) to fail to exercise collection remedies against 57

Specified Export Order Buyers or other Persons obligated on Collateral or to remove Liens on or any adverse claims against Collateral; (ii) to exercise collection remedies against Specified Export Order Buyers and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists; (iii) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature; (iv) to contact other Persons, whether or not in the same business as any Borrower, for expressions of interest in acquiring all or any portion of such Collateral; (v) to purchase insurance or credit enhancements to insure Agent against risks of loss, collection or disposition of Collateral or to provide to Agent a guaranteed return from the collection or disposition of Collateral; or (vi) to the extent deemed appropriate by Agent, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist Agent in the collection or disposition of any of the Collateral. Each Borrower acknowledges that the purpose of this Section 11.1(b) is to provide non- exhaustive indications of what actions or omissions by Agent would not be commercially unreasonable in Agent’s exercise of remedies against the Collateral and that other actions or omissions by Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 11.1(b). Without limitation upon the foregoing, nothing set forth in this Section 11.1(b) shall be construed to grant any rights to any Borrower or to impose any duties on Agent that would not have been granted or imposed by this Agreement or by Applicable Law in the absence of this Section 11.1(b). 11.2. Agent’s Discretion. Agent shall have the right to determine which rights, Liens, security interests or remedies Agent may at any time pursue, relinquish, subordinate, or modify, which procedures, timing and methodologies to employ, and what any other action to take with respect to any or all of the collateral and in what order, thereto and such determination will not in any way modify or affect any of Agent’s or Lenders’ rights hereunder as against Borrowers or each other. 11.3. Setoff. Subject to Section 14.13 hereof, in addition to any other rights which Agent or any Lender may have under Applicable Law, upon the occurrence and during the continuance of an Event of Default hereunder, Agent and such Lender shall have a right, immediately and without notice of any kind, to apply any Borrower’s property held by Agent and such Lender or any of their Affiliates to reduce the Obligations and to exercise any and all rights of setoff which may be available to Agent and such Lender with respect to any deposits held by Agent or such Lender. 11.4. Rights and Remedies not Exclusive. The enumeration of the foregoing rights and remedies is not intended to be exhaustive and the exercise of any rights or remedy shall not preclude the exercise of any other right or remedies provided for herein or otherwise provided by law, all of which shall be cumulative and not alternative. 11.5. Allocation of Payments and Proceeds of Collateral after Event of Default. Notwithstanding any provisions of this Agreement to the contrary: (a) After the occurrence and during the continuance of an Event of Default, all amounts collected or received by any Secured Party on account of the Obligations or in respect of the Collateral (including without limitation any and all payments paid by or on behalf of any Borrower (including any and all payments by or on behalf of any Guarantor in respect of its obligations and liabilities under its Guaranty), any and all proceeds of Collateral, any and all 58

(b) In the event that, notwithstanding the foregoing provisions of this Section 11.5, any Obligations Receipts shall be received by any Secured Party in violation of the terms of this Section 11.5, such amounts shall be held in trust for the benefit of the Secured Parties as a whole and shall promptly be paid over to or delivered to Agent in the form received (together with any applicable endorsement) for application. (c) For the avoidance of doubt, for all purposes under this Section 11.5, as applied to any category of Obligations and/or any clause under Section 11.5(a) hereof, “paid in full” means payment in cash of all amounts owing hereunder and under the Other Documents in respect of such Obligations and/or such clause of Section 11.5(a) hereof according to the terms hereof and of the Other Documents, including loan fees, service fees, professional fees and interest, default interest calculated at default rates, interest on interest and expense reimbursements, whether or not the same would be or is allowed or disallowed in whole or in part in any Insolvency Proceeding, and specifically including without limitation in the case of each clause under Section 11.5(a) hereof all Obligations of the type described in such clause 11.5(a) constituting Post-Petition Obligations, but, in each case, excluding contingent obligations for which no claim or demand for payment, whether oral or written, has been made. XII. WAIVERS AND JUDICIAL PROCEEDINGS. 12.1. Waiver of Notice. Each Borrower hereby waives notice of non-payment of any of the Specified Export Order Receivables, demand, presentment, protest and notice thereof with respect to any and all instruments, notice of acceptance hereof, notice of Advances made, credit extended, Collateral received or delivered, or any other action taken in reliance hereon, and all other demands and notices of any description, except such as are expressly provided for herein. 12.2. Delay. No delay or omission on Agent’s or any Lender’s part in exercising any right, remedy or option shall operate as a waiver of such or any other right, remedy or option or of any Default or Event of Default. 12.3. Jury Waiver. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, COUNTERCLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A) ARISING UNDER THIS AGREEMENT, ANY OTHER DOCUMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR (B) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO THIS AGREEMENT, ANY OTHER DOCUMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE WHETHER NOW EXISTING OR 60

HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE AND EACH PARTY HEREBY CONSENTS THAT ANY SUCH CLAIM, COUNTERCLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENTS OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. XIII. EFFECTIVE DATE AND TERMINATION. 13.1. Term. This Agreement, which shall inure to the benefit of and shall be binding upon the respective successors and permitted assigns of each Borrower, Agent and each Lender, shall become effective on the Closing Date and shall continue in full force and effect until the earlier of (a) August 30, 2021, and (b) any voluntary termination by the Borrowers of all of the Commitments hereunder (the “Term”), unless sooner terminated as herein provided; provided that, (x) Borrower may request extension of the last day of the Term to July 30, 2022 by sending written notice of such request to Agent no earlier than April 3, 2021, (y) upon receipt of any such notice requesting such an extension, Agent shall provide copies thereof promptly to Lenders, and (z) so long as and only if (I) the loan facility hereunder shall continue to be a Transaction Specific Loan Facility eligible for coverage (at a 95% level) under the Ex-Im Guarantee and (II) each Lender hereunder shall consent (in the exercise of its sole discretion) to such extension no later than thirty (30) days after Lenders’ shall have received copies of such notice from Agent, then such extension of the Term to July 30, 2022 shall occur (but further provided that, in connection therewith, Borrowers shall execute and/or deliver such amendments to this Agreement and/or the Notes, additional legal opinions, and additional/updated Ex-Im Agreement in order to effectuate such request as Agent shall reasonably request and Borrowers shall pay such additional fees with respect to such agreement to extend as any Lender and/or Ex-Im Bank shall require). 13.2. Termination. The termination of this Agreement shall not affect Agent’s or any Lender’s rights, or any of the Obligations having their inception prior to the effective date of such termination or any Obligations which pursuant to the terms hereof continue to accrue after such date, and the provisions hereof shall continue to be fully operative until all transactions entered into, rights or interests created and all of the Obligations have been Paid in Full. The security interests, Liens and rights granted to Agent and Lenders hereunder and the financing statements filed in connection herewith shall continue in full force and effect, notwithstanding the termination of this Agreement or the fact that Borrowers’ Account may from time to time be temporarily in a zero or credit position, until all of the Obligations have Paid in Full, the Commitments and this Agreement and the Other Documents have been terminated. Accordingly, each Borrower waives any rights which it may have under the Uniform Commercial Code to demand the filing of termination statements with respect to the Collateral, and Agent shall not be required to send such termination statements to each Borrower, or to file them with any filing office, unless and until this Agreement shall have been terminated in accordance with its terms and all Obligations have been Paid in Full. XIV. REGARDING AGENT. 14.1. Appointment. Each Lender hereby designates PNC to act as Agent for such Lender under this Agreement and the Other Documents. Each Lender hereby irrevocably authorizes 61

Agent to take such action on its behalf under the provisions of this Agreement and the Other Documents and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of Agent by the terms hereof and thereof and such other powers as are reasonably incidental thereto and Agent shall hold all Collateral, payments of principal and interest, fees (except the fees set forth in Sections 2.4(b) and in the Fee Letter), charges and collections received pursuant to this Agreement, for the ratable benefit of Lenders. Agent may perform any of its duties hereunder by or through its agents or employees. As to any matters not expressly provided for by this Agreement (including collection of the Note), Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of Required Lenders, and such instructions shall be binding; provided, however, that Agent shall not be required to take any action which, in Agent’s discretion, exposes Agent to liability or which is contrary to this Agreement or the Other Documents or Applicable Law unless Agent is furnished with an indemnification reasonably satisfactory to Agent with respect thereto. 14.2. Nature of Duties. Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the Other Documents. Neither Agent nor any of its officers, directors, employees or agents shall be (i) liable for any action taken or omitted by them as such hereunder or in connection herewith, unless caused by their bad faith, gross (not mere) negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment), or (ii) responsible in any manner for any recitals, statements, representations or warranties made by any Borrower or any officer thereof set forth in this Agreement, or in any of the Other Documents or in any certificate, report, statement or other document referred to or provided for in, or received by Agent under or in connection with, this Agreement or any of the Other Documents or for the value, validity, effectiveness, genuineness, due execution, enforceability or sufficiency of this Agreement, or any of the Other Documents or for any failure of any Borrower to perform its obligations hereunder. Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements set forth in, or conditions of, this Agreement or any of the Other Documents, or to inspect the properties, books or records of any Borrower. The duties of Agent as respects the Advances to Borrowers shall be mechanical and administrative in nature. Agent shall not have by reason of this Agreement a fiduciary relationship in respect of any Lender and nothing in this Agreement, expressed or implied, is intended to or shall be so construed as to impose upon Agent any obligations in respect of this Agreement or the transactions described herein except as expressly set forth herein. 14.3. Lack of Reliance on Agent. Independently and without reliance upon Agent or any other Lender, each Lender has made and shall continue to make (i) its own independent investigation of the financial condition and affairs of each Borrower in connection with the making and the continuance of the Advances hereunder and the taking or not taking of any action in connection herewith, and (ii) its own appraisal of the creditworthiness of each Borrower. Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before making of the Advances or at any time or times thereafter except as shall be provided by any Borrower pursuant to the terms hereof. Agent shall not be responsible to any Lender for any recitals, statements, information, representations or warranties herein or in any agreement, document, certificate or a statement delivered in connection with or for the execution, effectiveness, genuineness, validity, enforceability, collectability or sufficiency of this Agreement 62

or any Other Document, or of the financial condition of any Borrower, or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement, the Notes, the Other Documents or the financial condition or prospects of any Borrower, or the existence of any Event of Default or any Default. 14.4. Resignation of Agent; Successor Agent. Agent may resign on sixty (60) days written notice to each of Lenders and Borrowing Agent and upon such resignation, Required Lenders will promptly designate a successor Agent reasonably satisfactory to Borrowing Agent (provided that no such approval by Borrowing Agent shall be required (i) in any case where the successor Agent is one of Lenders or (ii) after the occurrence and during the continuance of any Event of Default). Any such successor Agent shall succeed to the rights, powers and duties of Agent, and shall in particular succeed to all of Agent’s right, title and interest in and to all of the Liens in the Collateral securing the Obligations created hereunder or any Other Document, and the term “Agent” shall mean such successor agent effective upon its appointment, and the former Agent’s rights, powers and duties as Agent shall be terminated, without any other or further act or deed on the part of such former Agent. However, notwithstanding the foregoing, if at the time of the effectiveness of the new Agent’s appointment, any further actions need to be taken in order to provide for the legally binding and valid transfer of any Liens in the Collateral from former Agent to new Agent and/or for the perfection of any Liens in the Collateral as held by new Agent or it is otherwise not then possible for new Agent to become the holder of a fully valid, enforceable and perfected Lien as to any of the Collateral, former Agent shall continue to hold such Liens solely as agent for perfection of such Liens on behalf of new Agent until such time as new Agent can obtain a fully valid, enforceable and perfected Lien on all Collateral, provided that Agent shall not be required to or have any liability or responsibility to take any further actions after such date as such agent for perfection to continue the perfection of any such Liens (other than to forego from taking any affirmative action to release any such Liens). After Agent’s resignation as Agent, the provisions of this Article XIV, and any indemnification rights under this Agreement, including without limitation, rights arising under Section 16.5 hereof, shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement (and in the event resigning Agent continues to hold any Liens pursuant to the provisions of the immediately preceding sentence, the provisions of this Article XIV and any indemnification rights under this Agreement, including without limitation, rights arising under Section 16.5 hereof, shall inure to its benefit as to any actions taken or omitted to be taken by it in connection with such Liens). 14.5. Certain Rights of Agent. If Agent shall request instructions from Lenders with respect to any act or action (including failure to act) in connection with this Agreement or any Other Document, Agent shall be entitled to refrain from such act or taking such action unless and until Agent shall have received instructions from Required Lenders; and Agent shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, Lenders shall not have any right of action whatsoever against Agent as a result of its acting or refraining from acting hereunder in accordance with the instructions of Required Lenders. 14.6. Reliance. Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, statement, certificate, email, facsimile or telecopier message, order or other document or telephone message believed by it to be genuine and correct and to have been signed, sent or made by the proper person or entity, and, with respect to all legal matters pertaining to this Agreement and the Other Documents and its duties hereunder, upon advice of counsel selected by it. Agent may employ agents and attorneys-in-fact and shall not be 63

liable for the default or misconduct of any such agents or attorneys-in-fact selected by Agent with reasonable care. 14.7. Notice of Default. Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder or under the Other Documents, unless Agent has received notice from a Lender or Borrowing Agent referring to this Agreement or the Other Documents, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that Agent receives such a notice, Agent shall give notice thereof to Lenders. Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by Required Lenders; provided, that, unless and until Agent shall have received such directions, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of Lenders. 14.8. Indemnification. To the extent Agent is not reimbursed and indemnified by Borrowers, each Lender will reimburse and indemnify Agent in proportion to its respective portion of the outstanding Advances (or, if no Advances are outstanding, pro rata according to the percentage that its Commitment Amount constitutes of the total aggregate Commitment Amounts), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against Agent in performing its duties hereunder, or in any way relating to or arising out of this Agreement or any Other Document; provided that Lenders shall not be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Agent’s bad faith, gross (not mere) negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment). 14.9. Agent in its Individual Capacity. With respect to the obligation of Agent to lend under this Agreement, the Advances made by it shall have the same rights and powers hereunder as any other Lender and as if it were not performing the duties as Agent specified herein; and the term “Lender” or any similar term shall, unless the context clearly otherwise indicates, include Agent in its individual capacity as a Lender. Agent may engage in business with any Borrower as if it were not performing the duties specified herein, and may accept fees and other consideration from any Borrower for services in connection with this Agreement or otherwise without having to account for the same to Lenders. 14.10. Delivery of Documents. To the extent Agent receives reports, information, or financial statements required under Sections 9.1 and 9.2 hereof any Borrower pursuant to the terms of this Agreement which any Borrower is not obligated to deliver to each Lender, Agent will promptly deliver such documents and information to Lenders. 14.11. Borrowers’ Undertaking to Agent. Without prejudice to their respective obligations to Lenders under the other provisions of this Agreement, each Borrower hereby undertakes with Agent to pay to Agent from time to time on demand all amounts from time to time due and payable by it for the account of Agent or Lenders or any of them pursuant to this Agreement to the extent not already paid. Any payment made pursuant to any such demand shall pro tanto satisfy the relevant Borrower’s obligations to make payments for the account of Lenders or the relevant one or more of them pursuant to this Agreement. 64

14.12. No Reliance on Agent’s Customer Identification Program. To the extent the Advances or this Agreement is, or becomes, syndicated in cooperation with other Lenders, each Lender acknowledges and agrees that neither such Lender, nor any of its Affiliates, participants or assignees, may rely on Agent to carry out such Lender's, Affiliate's, participant's or assignee's customer identification program, or other obligations required or imposed under or pursuant to the USA PATRIOT Act or the regulations thereunder, including the regulations contained in 31 CFR 103.121 (as hereafter amended, modified, supplemented or replaced, the “CIP Regulations”), or any other Anti-Terrorism Law, including any programs involving any of the following items relating to or in connection with any of Borrowers, their Affiliates or their agents, the Other Documents or the transactions hereunder or contemplated hereby: (i) any identity verification procedures, (ii) any recordkeeping, (iii) comparisons with government lists, (iv) customer notices or (v) other procedures required under the CIP Regulations or such Anti-Terrorism Laws. 14.13. Other Agreements. Each of Lenders agrees that it shall not, without the prior written consent of Agent, and that it shall, to the extent it is lawfully entitled to do so, upon the request of Agent, set off against the Obligations, any amounts owing by such Lender to any Borrower or any deposit accounts of any Borrower now or hereafter maintained with such Lender. Anything in this Agreement to the contrary notwithstanding, each of Lenders further agrees that it shall not, unless specifically requested to do so by Agent, take any action to protect or enforce its rights arising out of this Agreement or the Other Documents, it being the intent of Lenders that any such action to protect or enforce rights under this Agreement and the Other Documents shall be taken in concert and at the direction or with the consent of Agent or Required Lenders. XV. BORROWING AGENCY. 15.1. Borrowing Agency Provisions. (a) Each Borrower hereby irrevocably designates Borrowing Agent to be its attorney and agent and in such capacity whether verbally, in writing or through electronic methods (including, without limitation, an Approved Electronic Communication) to (i) borrow, (ii) request advances, (iii) sign and endorse notes, (iv) execute and deliver all instruments, documents, applications, security agreements, and other agreements, documents, instruments, certificates, notices, writings and further assurances now or hereafter required hereunder, (v) make elections regarding interest rates, and (vii) otherwise take action under and in connection with this Agreement and the Other Documents, all on behalf of and in the name of such Borrower or Borrowers, and hereby authorizes Agent to pay over or credit all loan proceeds hereunder in accordance with the request of Borrowing Agent. (b) The handling of this credit facility as a co-borrowing facility with a borrowing agent in the manner set forth in this Agreement is solely as an accommodation to Borrowers and at their request. Neither Agent nor any Lender shall incur liability to Borrowers as a result thereof. To induce Agent and Lenders to do so and in consideration thereof, each Borrower hereby indemnifies Agent and each Lender and holds Agent and each Lender harmless from and against any and all liabilities, expenses, losses, damages and claims of damage or injury asserted against Agent or any Lender by any Person arising from or incurred by reason of the handling of the financing arrangements of Borrowers as provided herein, reliance by Agent or any Lender on any request or instruction from Borrowing Agent or any other action taken by Agent or any Lender with respect to this Section 15.1 except due to bad faith, willful misconduct or gross (not mere) 65

negligence by the indemnified party (as determined by a court of competent jurisdiction in a final and non-appealable judgment). (c) All Obligations shall be joint and several, and each Borrower shall make payment upon the maturity of the Obligations by acceleration or otherwise, and such obligation and liability on the part of each Borrower shall in no way be affected by any extensions, renewals and forbearance granted by Agent or any Lender to any Borrower, failure of Agent or any Lender to give any Borrower notice of borrowing or any other notice, any failure of Agent or any Lender to pursue or preserve its rights against any Borrower, the release by Agent or any Lender of any Collateral now or thereafter acquired from any Borrower, and such agreement by each Borrower to pay upon any notice issued pursuant thereto is unconditional and unaffected by prior recourse by Agent or any Lender to the other Borrowers or any Collateral for such Borrower’s Obligations or the lack thereof. Each Borrower waives all suretyship defenses. 15.2. Waiver of Subrogation. Each Borrower expressly waives any and all rights of subrogation, reimbursement, indemnity, exoneration, contribution of any other claim which such Borrower may now or hereafter have against the other Borrowers or any other Person directly or contingently liable for the Obligations hereunder, or against or with respect to any other Borrower’s property (including, without limitation, any property which is Collateral for the Obligations), arising from the existence or performance of this Agreement, until the termination of the Commitments, the termination of this Agreement and the Payment in Full of the Obligations. XVI. MISCELLANEOUS. 16.1. Governing Law; Venue; Jurisdiction. This Agreement and each Other Document (unless and except to the extent expressly provided otherwise in any such Other Document), and all matters relating hereto or thereto or arising herefrom or therefrom (whether arising under contract law, tort law or otherwise) shall, in accordance with Section 5-1401 of the General Obligations Law of the State of New York, be governed by and construed in accordance with the laws of the State of New York. Any judicial proceeding brought by or against any Borrower with respect to any of the Obligations, this Agreement or any of the Other Documents shall be brought in any court of competent jurisdiction in the County of New York, State of New York, United States of America, and, by execution and delivery of this Agreement, each Borrower accepts for itself and in connection with its properties, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts, and irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement. Each Borrower hereby waives personal service of any and all process upon it and consents that all such service of process may be made by certified or registered mail (return receipt requested) directed to Borrowing Agent at its address set forth in Section 16.6 hereof and service so made shall be deemed completed five (5) days after the same shall have been so deposited in the mails of the United States of America. Nothing herein shall affect the right to serve process in any manner permitted by law. Each Borrower waives any objection to jurisdiction and venue of any action instituted hereunder in compliance with this Section 16.1 and shall not assert any defense based on lack of jurisdiction or venue or based upon forum non conveniens. Any judicial proceeding by any Borrower against Agent or any Lender involving, directly or indirectly, any matter or claim in any way arising out of, related to or connected with this Agreement or any of the Other Documents shall be brought only in a federal or state court located in the County of New York, State of New York. 66

16.2. Entire Understanding. (a) This Agreement and the Other Documents contain the entire understanding between each Borrower, Agent and each Lender and supersedes all prior agreements and understandings, if any, relating to the subject matter hereof. Any promises, representations, warranties or guarantees not herein contained and hereinafter made shall have no force and effect unless in writing, signed by each Borrower’s, Agent’s and each Lender’s respective officers. Neither this Agreement nor any portion or provisions hereof may be amended, modified, waived, supplemented, discharged, cancelled or terminated orally or by any course of dealing, or in any manner other than by an agreement in writing, signed by the party to be charged. Notwithstanding the foregoing, Agent may modify this Agreement or any of the Other Documents for the purposes of completing missing content or correcting erroneous content of an administrative nature, without the need for a written amendment, provided that Agent shall send a copy of any such modification to Borrowers and each Lender (which copy may be provided by electronic mail). Each Borrower acknowledges that it has been advised by counsel in connection with the execution of this Agreement and Other Documents and is not relying upon oral representations or statements inconsistent with the terms and provisions of this Agreement. (b) Required Lenders, Agent with the consent in writing of Required Lenders, and the Borrowers may, subject to the provisions of this Section 16.2(b), from time to time enter into any written amendments to this Agreement or any of the Other Documents or any other supplemental agreements, documents or instruments for the purpose of adding or deleting any provisions or otherwise amending, modifying, supplementing, changing, varying or waiving in any manner the conditions, provisions or terms hereof or thereof or waiving any Event of Default hereunder or thereunder, but only to the extent specified in such written amendments or other agreements, documents or instruments; provided, however, that no such amendment, or other agreement, document or instrument shall: (i) increase the Commitment or the maximum dollar amount of the Commitment Amount of any Lender without the consent of such Lender directly affected thereby; (ii) whether or not any Advances are outstanding, extend the Term or the time for payment of principal or interest of any Advance (excluding the due date of any mandatory prepayment of an Advance), or any fee payable to any Lender, or reduce the principal amount of or the rate of interest borne by any Advances or reduce any fee payable to any Lender, without the consent of each Lender directly affected thereby (except that Required Lenders may elect to waive or rescind any imposition of the Default Rate under Section 3.1 hereof); (iii) alter the definition of the term “Required Lenders” or alter, amend or modify this Section 16.2(b) without the consent of all Lenders; (iv) alter, amend or modify the provisions of Section 11.5 hereof without the consent of all Lenders; (v) release all or substantially all of the Collateral without the consent of each Lender directly and adversely affected thereby; (vi) change the rights and duties of Agent without the consent of all Lenders and Agent; 67

(vii) release any Borrower without the consent of all Lenders; or (viii) subordinate the Liens of Agent in the Collateral in favor of any other Liens without the consent of all Lenders. (c) Any such supplemental agreement shall apply equally to each Lender and shall be binding upon Borrowers, Lenders and Agent and all future holders of the Obligations. In the case of any waiver, Borrowers, Agent and Lenders shall be restored to their former positions and rights, and any Event of Default waived shall be deemed to be cured and not continuing, but no waiver of a specific Event of Default shall extend to any subsequent Event of Default (whether or not the subsequent Event of Default is the same as the Event of Default which was waived), or impair any right consequent thereon. (d) Agent is hereby authorized by Borrowers and Lenders, at any time in Agent’s sole discretion regardless of (i) the existence of a Default or an Event of Default, (ii) whether any of the other applicable conditions precedent set forth in Section 8.2 hereof have not been satisfied or the Commitments have been terminated for any reason, or (iii) any other contrary provision of this Agreement, to make Advances to Borrowers on behalf of Lenders which Agent, in its reasonable business judgment, deems necessary or desirable (a) to preserve or protect the Collateral, or any portion thereof, (b) to enhance the likelihood of, or maximize the amount of, repayment of the Advances and other Obligations, or (c) to pay any other amount chargeable to Borrowers pursuant to the terms of this Agreement (any such Advances, the “Protective Advances”); provided, that the Protective Advances made hereunder shall not exceed $25,000,000 in the aggregate without the consent of Required Lenders. The Lenders shall be obligated to fund such Advances and effect a settlement with Agent therefore upon demand of Agent in accordance with their respective Commitment Percentages. To the extent any Protective Advances are not actually funded by the other Lenders as provided for in this Section 16.2(f), any such Protective Advances funded by Agent shall be deemed to be Advances made by and owing to Agent, and Agent shall be entitled to all rights (including accrual of interest) and remedies of a Lender under this Agreement and the Other Documents with respect to such Advances. 16.3. Successors and Assigns; Participations; New Lenders. (a) This Agreement shall be binding upon and inure to the benefit of Borrowers, Agent, each Lender, all future holders of the Obligations and their respective successors and assigns, except that no Borrower may assign or transfer any of its rights or obligations under this Agreement without the prior written consent of Agent and each Lender. (b) Each Borrower acknowledges that in the regular course of commercial banking business one or more Lenders may at any time and from time to time sell participating interests in the Advances to other Persons (other than natural person (or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural person))) (each such transferee or purchaser of a participating interest, a “Participant”); provided that (i) such Lender’s obligations under this Agreement and the Other Documents shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) each Borrower, Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and the Other 68

Documents and to approve any amendment, modification or waiver hereto or thereto; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in clause (i) or (ii) of the first proviso to Section 16.2(b) that affects such Participant. Each Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.6, 3.8 and 3.9 of this Agreement (subject to the requirements and limitations therein, including the obligation to deliver documentation under Section 3.9(e) it being understood that such documentation shall be delivered to the participating Lender) to the same extent as if it were a Purchasing Lender; provided that (i) Borrowers shall not be required to pay to any Participant more than the amount which it would have been required to pay to Lender which granted an interest in its Advances or other Obligations payable hereunder to such Participant had such Lender retained such interest in the Advances hereunder or other Obligations payable hereunder unless the sale of the participation to such Participant is made with Borrower’s prior written consent and (ii) in no event shall Borrowers be required to pay any such amount arising from the same circumstances and with respect to the same Advances or other Obligations payable hereunder to both such Lender and such Participant. 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 principal amount (and stated interest) of each Participant’s interest in the Advances or other Obligations (the “Participant Register”); provided that no Lender shall have any obligation to disclose the identity or any information relating to a Participant’s interest in any Advances or other Obligations to any Person except to the extent that such disclosure is necessary to establish that such Advance or other Obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in each 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. For the avoidance of doubt Agent (in its capacity as such) shall have no responsibility for maintaining a Participant Register. (c) Any Lender may sell, assign or transfer all or any part of its rights and obligations under or relating to any of the Advances or Commitments of such Lender under this Agreement and the Other Documents to one or more entities (other than (x) a natural person (or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural person) or (y) a Defaulting Lender) (each a “Purchasing Lender”), in minimum amounts of not less than $5,000,000, pursuant to a Commitment Transfer Supplement, executed by a Purchasing Lender, the transferor Lender, and Agent and delivered to Agent for recording, provided, however, each such sale, assignment or transfer by any Lender prior to the termination of such Lender’s Commitment must consist of an assignment by such Lender of both the designated portion of such Lender’s Commitment (which may be all of such Commitment) and of that portion of the Advances held by such Lender as is proportionate to that portion of such Lender’s Commitment so sold, assigned or transferred. Upon such execution, delivery, acceptance and recording, from and after the transfer effective date determined pursuant to such Commitment Transfer Supplement, (i) Purchasing Lender thereunder shall be a party hereto and, to the extent provided in such Commitment Transfer Supplement, have the rights and obligations of a Lender hereunder with respect to the Advances and, if applicable, Commitments transferred to such Purchasing Lender under such Commitment Transfer Supplement, and (ii) the transferor Lender thereunder shall, to the extent provided in such Commitment Transfer Supplement, be released from its obligations under this Agreement. Such Commitment Transfer Supplement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the 69

addition of such Purchasing Lender and, if and as applicable, the resulting adjustment of the Commitment Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. Each Borrower hereby consents to the addition of such Purchasing Lender and, if and as applicable, the resulting adjustment of the Commitment Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. Borrowers shall execute and deliver such further documents and do such further acts and things in order to effectuate the foregoing; provided, however, that the consent of Borrowers (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default under Section 10.1 or 10.5 has occurred and is continuing at the time of such assignment or (y) such assignment is to a Permitted Assignee; provided that Borrowers shall be deemed to have consented to any such assignment unless Borrowing Agent shall object thereto by written notice to Agent within ten (10) Business Days after having received prior notice thereof. (d) [Reserved]. (e) Agent shall maintain at its address a copy of each Commitment Transfer Supplement and Modified Commitment Transfer Supplement delivered to it and a register (the “Register”) for the recordation of the names and addresses of each Lender and the outstanding principal, accrued and unpaid interest and other fees due hereunder. The entries in the Register shall be conclusive, in the absence of manifest error, and each Borrower, Agent and Lenders may treat each Person whose name is recorded in the Register as the owner of the Advance recorded therein for the purposes of this Agreement. The Register shall be available for inspection by Borrowing Agent or any Lender (with respect to its own holdings) at any reasonable time and from time to time upon reasonable prior notice. Agent shall receive a fee in the amount of $3,500 payable by the applicable Purchasing Lender and/or Purchasing CLO upon the effective date of each transfer or assignment (other than to an intermediate purchaser or to a Permitted Assignee) to such Purchasing Lender and/or Purchasing CLO and, if and as applicable, the resulting adjustment of the Commitment Percentages arising therefrom. (f) Each Borrower authorizes each Lender to disclose to any Participant or Purchasing Lender and any prospective Participant or Purchasing Lender any and all financial information in such Lender’s possession concerning such Borrower which has been delivered to such Lender by or on behalf of such Borrower pursuant to this Agreement or in connection with such Lender’s credit evaluation of such Borrower, subject to such Participant, Purchasing Lender, prospective Participant or prospective Purchasing Lender agreeing to confidentiality restrictions substantially consistent with Section 16.15. (g) Notwithstanding anything to the contrary set forth in this Agreement, any Lender may at any time and from time to time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. (h) Notwithstanding anything to the contrary contained in this Section 16.3 (specifically including subsections (b), (c) or (d) hereof) or otherwise provided for in this 70

Agreement or in any Other Document including any Note, following the occurrence and during the continuance of any Event of Default, Agent may, in its sole discretion, elect to exercise all rights and remedies under the Ex-Im Master Guarantee on behalf of itself and all Lenders (and Lenders hereby authorize Agent to do the same), and each Lender hereby agrees to take any and all actions requested by Agent (at Borrowers’ expense (and Borrower’s liabilities to pay for such expenses shall be part of the Obligations hereunder secured by the Collateral)), including execution and delivery of any instruments of assignment in favor of Ex-Im Bank with respect to its Notes and its interests in this Agreement and the Other Documents and in the Advances hereunder, as shall be necessary for Agent to fully exercise all such rights and remedies in compliance with all the requirements of the Ex-Im Agreements including Section 5.01(a) and 5.01(b) of the Ex-Im Master Guarantee. 16.4. Application of Payments. Agent shall have the continuing and exclusive right to apply or reverse and re-apply any payment and any and all proceeds of Collateral to any portion of the Obligations. To the extent that any Borrower makes a payment or Agent or any Lender receives any payment or proceeds of the Collateral for any Borrower’s benefit, which are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver, custodian or any other party under any bankruptcy law, common law or equitable cause, then, to such extent, the Obligations or part thereof intended to be satisfied shall be revived and continue as if such payment or proceeds had not been received by Agent or such Lender. 16.5. Indemnity. Each Borrower shall indemnify and hold harmless Agent, each Lender and each of their respective officers, directors, Affiliates, attorneys, employees and agents (each an “Indemnified Party”) for and from and against any and all claims, liabilities, losses, damages and related expenses (including fees and disbursements of a single firm of counsel to the Indemnified Parties, taken as a whole) (collectively, “Claims”) which may be imposed on, incurred by, or asserted against any Indemnified Party in arising out of or in connection with: (i) the execution or delivery of this Agreement, the Other Documents, the performance thereof by the parties thereto, the Advances and other Obligations and/or the transactions contemplated hereby including the Transactions, (ii) any action or failure to act or action taken only after delay or the satisfaction of any conditions by any Indemnified Party in connection with and/or relating to the negotiation, execution, delivery or administration of the Agreement and the Other Documents, the credit facilities established hereunder and thereunder and/or the transactions contemplated hereby including the Transactions, (iii) the enforcement of any of the rights and remedies of Agent or any Lender under the Agreement and the Other Documents, (iv) any actual alleged presence or release of Hazardous Materials on or from any property currently or formerly owned by a Borrower and (v) any claim, litigation, proceeding or investigation instituted or conducted by any Governmental Body or instrumentality, any Borrower, any Affiliate or Subsidiary of any Borrower or any other Person with respect to any aspect of, or any transaction contemplated by, or referred to in, or any matter related to, this Agreement or the Other Documents, whether or not Agent or any Lender is a party thereto; provided that (u) such indemnity shall not be available to any Indemnified Party to the extent that such Claims are determined by a court of competent jurisdiction in a final and nonappealable judgment to have resulted from the bad faith, gross (not mere) negligence or willful misconduct of such Indemnified Party, (w) such indemnity shall not be available to any Indemnified Party for Claims arising out of a proceeding in which such Indemnified Party and any Borrower or any Affiliate thereof are adverse parties involving a material breach in bad faith by such Indemnified Party to the extent that such Borrower or Affiliate thereof prevails on the merits, 71

as determined by a court of competent jurisdiction in a final and nonappealable judgment (it being understood that nothing in this Agreement shall preclude a claim or suit by any Borrower against any Indemnified Party for such Indemnified Party’s failure to perform any of its obligations under this Agreement or any Other Document), (x) the Borrowers shall not, in connection with any such proceeding or related proceedings in the same jurisdiction and in the absence of actual conflicts of interest, be liable for the fees and expenses of more than one firm of counsel at any one time for the Indemnified Parties, (y) each Indemnified Party shall give the Borrowers (I) prompt notice of any such action brought against such Indemnified Party in connection with a Claim for which it intends to assert entitlement to the indemnity hereunder and (II) an opportunity to consult from time to time with such Indemnified Party regarding defensive measures and potential settlement and (z) the Borrowers shall not be obligated to pay the amount of any settlement entered into without its written consent. 16.6.

Consequential Damages. No party hereto, nor any agent or attorney for any of them, shall be liable to any other party hereto (or any Affiliate thereof) for indirect, punitive, exemplary or consequential damages arising from any breach of contract, tort or other wrong relating to the establishment, administration or collection of the Obligations or as a result of any transaction contemplated under this Agreement or any Other Document. 16.12.

Confidentiality; Sharing Information. Agent, each Lender, each Participant and each Purchasing Lender shall maintain the confidentiality of all non-public information obtained by Agent, such Lender, such Participant or such Purchasing Lender; provided, however, Agent, each Lender, each Participant and each Purchasing Lender may disclose such confidential 74

information (a) to its examiners, Affiliates, directors, officers, partners, employees, agents, auditors, counsel and other professional advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such information and instructed to keep such information confidential), (b) to Agent, any Lender or, subject to an agreement containing provisions substantially the same as those of this Section 16.15, to any prospective Participant or Purchasing Lender, and (c) as required or requested by any Governmental Body or representative thereof or pursuant to legal process; provided, further that unless specifically prohibited by Applicable Law, Agent, each Lender, each Participant and each Purchasing Lender shall use its reasonable best efforts prior to disclosure thereof, to notify the applicable Borrower of the applicable request for disclosure of such non-public information and, to the extent feasible, give the applicable Borrower an opportunity to lawfully object to such disclosure (A) by a Governmental Body or representative thereof (other than any such request in connection with an examination of the financial condition of a Lender, Participant or Purchasing Lender by such Governmental Body) or (B) pursuant to legal process.

Such authorization shall survive the repayment of the other Obligations and the termination of this Agreement. Notwithstanding any non-disclosure agreement or similar document executed by Agent in favor of any Borrower or any of any Borrower’s affiliates, the provisions of this Agreement shall supersede such agreements. 16.16. Publicity. With the reasonable consent of the Borrowing Agent, the Agent may make appropriate announcements of the financial arrangement entered into among Borrowers, Agent and Lenders, including announcements which are commonly known as tombstones, in such publications and to such selected parties as Agent and Borrowing Agent may reasonably deem appropriate. 16.17. Certifications From Banks and Participants; USA PATRIOT Act. (a) Each Lender or assignee or participant of a Lender that is not incorporated under the Laws of the United States of America or a state thereof (and is not excepted from the certification requirement contained in Section 313 of the USA PATRIOT Act and the applicable regulations because it is both (i) an affiliate of a depository institution or foreign bank that maintains a physical presence in the United States or foreign country, and (ii) subject to supervision by a banking authority regulating such affiliated depository institution or foreign bank) shall deliver to Agent the certification, or, if applicable, recertification, certifying that such Lender is not a “shell” and certifying to other matters as required by Section 313 of the USA PATRIOT Act and the applicable regulations: (1) within ten (10) days after the Closing Date, and (2) as such other times as are required under the USA PATRIOT Act.
