Unless otherwise specified herein, capitalized and/or initially capitalized terms used in this Amendment shall have the meanings ascribed to them in the Amended Credit Agreement (as hereinafter defined). A. WHEREAS, Borrower, the Guarantors, certain financial institutions parties thereto (the “Lenders”) and the Administrative Agent are parties to that certain Credit Agreement, dated as of October 2, 2019 (as has been and may be further amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”); and B. WHEREAS, the Borrower, the other Loan Parties, the Administrative Agent and the Lenders party hereto, which constitute Required Lenders, have agreed to amend the Credit Agreement pursuant to an Early Opt-in Election under and as defined in the Credit Agreement (as in effect immediately prior to giving effect to this Amendment), subject to the terms and conditions set forth herein. NOW, THEREFORE, for and in consideration of the premises and mutual agreements herein contained and for the purposes of setting forth the terms and conditions of this Amendment and for other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be bound, hereby agree as follows: 1. Amendments to Credit Agreement. Subject to the terms and conditions of this Amendment, the Credit Agreement is hereby amended as follows: (a) the Credit Agreement (exclusive of all Exhibits and Schedules thereto, except as otherwise described in this Section 1) is hereby amended and restated in its entirety as set forth in Exhibit A attached hereto (the “Amended Credit Agreement”). (b) Exhibit B to the Credit Agreement is deleted in its entirety and Exhibit B hereto is hereby substituted therefor. (c) Exhibit C to the Credit Agreement is deleted in its entirety and Exhibit C hereto is hereby substituted therefor. 2. Conditions Precedent to Amendment. This Amendment shall become effective upon the Administrative Agent receiving copies, in form and substance reasonably satisfactory to the Administrative Agent, of this Amendment duly executed by the Borrower, the Guarantors, the Administrative Agent and the Required Lenders. 3. Fees and Expenses.

2 obligations hereunder, (b) no Default or Event of Default exists both before and after giving effect to this Amendment, (c) this Amendment and the Loan Documents, as amended hereby, constitute the legal, valid and binding obligations of Borrower and Guarantors and are enforceable against Borrower and Guarantors in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance or similar laws affecting creditors’ rights generally and general principles of equity (regardless of whether the application of such principles is considered in a proceeding in equity or at law), (d) all Liens created under the Loan Documents continue to be first priority (subject only to Permitted Encumbrances) perfected Liens, and (e) all representations and warranties of Borrower and Guarantors contained in the Amended Credit Agreement and all other Loan Documents are true and correct in all material respects (except that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof) as though made on and as of the date hereof (except to the extent such representations and warranties relate to an earlier date, in which case they are true and correct in all material respects as of such date). 5. Ratification. Except as expressly modified in this Amendment, all of the terms, provisions and conditions of the Credit Agreement, as heretofore amended, shall remain unchanged and in full force and effect. Except as herein specifically agreed, the Credit Agreement and each other Loan Document are hereby ratified and confirmed and shall remain in full force and effect according to their terms. Except as specifically set forth herein, the execution, delivery and effectiveness of this Amendment shall not operate as a waiver of any right, power or remedy of the Administrative Agent, the Lenders or the L/C Issuer under the Credit Agreement or any of the other Loan Documents, or constitute a waiver of any provision of the Credit Agreement or any of the other Loan Documents. This Amendment shall not constitute a course of dealing with the Administrative Agent, the Lenders or the L/C Issuer at variance with the Credit Agreement or the other Loan Documents such as to require further notice by such Person to require strict compliance with the terms of the Amended Credit Agreement and the other Loan Documents in the future. Borrower and the Guarantors acknowledge and expressly agree that the Administrative Agent, each Lender and the L/C Issuer reserves the right to, and does in fact, require strict compliance with all terms and provisions of the Credit Agreement and the other Loan Documents. Each of Borrower and the Guarantors hereby: (i) affirms that it is indebted to the Lenders under the terms and conditions of the Credit Agreement and the other Loan Documents, each of which constitutes the valid and binding obligation of Borrower and the Guarantors, enforceable in accordance with their respective terms, except as enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance or similar laws affecting creditors’ rights generally and general principles of equity (regardless of whether the application of such principles is considered in a proceeding in equity or at law), and that no offsets, expenses or counterclaims to its obligations thereunder exist; and (ii) affirmatively waives any right to challenge the liens and security interests granted in favor of the Administrative Agent under the Credit Agreement, the other Loan Documents or hereunder. 6. Governing Law. This Amendment and any claim, controversy, dispute or cause of action (whether in contract, tort or otherwise) based upon, arising out of or relating to this Amendment, and the rights and duties of the parties hereto, shall be governed by and construed and determined in accordance with the internal laws of the State of New York. 7. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AMENDMENT OR ANY LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).

3 8. Miscellaneous. (a) Counterparts. This Amendment may be executed in any number of counterparts, and by the different parties hereto on separate counterpart signature pages, each of which shall constitute an original, and all such counterparts taken together shall be deemed to constitute one and the same instrument. Each of the parties hereto agrees that a signature transmitted to the other parties hereto or their respective counsel by telecopier or other electronic transmission shall be as effective to bind the party whose signature was transmitted as a duly executed and delivered original. (b) Severability of Provisions. Any provision of this Amendment which is unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction. All rights, remedies and powers provided in this Amendment and the other Loan Documents may be exercised only to the extent that the exercise thereof does not violate any applicable mandatory provisions of law, and all the provisions of this Amendment and other Loan Documents are intended to be subject to all applicable mandatory provisions of law which may be controlling and to be limited to the extent necessary so that they will not render this Amendment or the other Loan Documents invalid or unenforceable. (c) Incorporation. This Amendment shall form a part of the Credit Agreement, and all references to the Credit Agreement shall mean that document as hereby modified. Upon the effectiveness of this Amendment, each reference in the Credit Agreement to “this Agreement”, “hereunder”, “hereof”, “herein” or words of similar import shall mean and be a reference to the Credit Agreement as amended hereby.

-3- 751970602 Level Total Leverage Ratio Applicable Margin for Base Rate Loans under Revolving Credit and Term Credit and Reimbursement Obligations shall be: Applicable Margin for SOFR Loans under Revolving Credit and Term Credit and Letter of Credit Fee shall be: Applicable Margin for Commitment Fee shall be: IV Greater than or equal to 3.00 to 1.0 2.00% 3.00% 0.35% III Less than 3.00 to 1.0, but greater than or equal to 2.25 to 1.0 1.50% 2.50% 0.30% II Less than 2.25 to 1.0, but greater than or equal to 1.50 to 1.0 1.00% 2.00% 0.25% I Less than 1.50 to 1.0 0.50% 1.50% 0.20%; provided that the Applicable Margin for Letter of Credit fees in respect of performance letters of credit shall be 67% of the applicable rates per annum set forth above. For purposes hereof, the term “Pricing Date” means, for any fiscal quarter of Borrower ending on or after September 30, 2021, the date on which Administrative Agent is in receipt of Borrower’s most recent financial statements (and, in the case of the year-end financial statements, audit report) for the fiscal quarter then ended, pursuant to Section 6.5. The Applicable Margin shall be established based on the Total Leverage Ratio for the most recently completed fiscal quarter and the Applicable Margin established on a Pricing Date shall remain in effect until the next Pricing Date. If Borrower has not delivered its financial statements by the date such financial statements (and, in the case of the year-end financial statements, audit report) are required to be delivered under Section 6.5, until such financial statements and audit report are delivered, the Applicable Margin shall be the highest Applicable Margin (i.e., Level IV shall apply). If Borrower subsequently delivers such financial statements before the next Pricing Date, the Applicable Margin established by such late delivered financial statements shall take effect from the date of delivery until the next Pricing Date. In all other circumstances, the Applicable Margin established by such financial statements shall be in effect from the Pricing Date that occurs immediately after the end of the fiscal quarter covered by such financial statements until the next Pricing Date. Each determination of the Applicable Margin made by Administrative Agent in accordance with the foregoing shall be conclusive and binding on Borrower and the Lenders absent manifest error. If, as a result of any restatement of or other adjustment to the financial statements of the Borrower or for any other reason, the Borrower or the Administrative Agent determines that (i) the Total Leverage Ratio as calculated by the Borrower as of any applicable date was inaccurate and (ii) a proper calculation of the Total Leverage Ratio would have resulted in higher pricing for such period, the Borrower shall immediately and retroactively be obligated to pay to the Administrative Agent for the account of the applicable Lenders or the L/C Issuer, as the case may be, promptly on

The Administrative Agent may select information sources or services in its reasonable discretion to ascertain the Benchmark or any other Benchmark, in each case pursuant to the terms of this Agreement, and shall have no liability to the Borrower, any Lender or any other person or entity for damages of any kind, including direct or indirect, special, punitive, incidental or consequential damages, costs, losses or expenses (whether in tort, contract or otherwise and whether at law or in equity), for any error or calculation of any such rate (or component thereof) provided by any such information source or service.

-35- 751970602 SECTION 2. THE CREDIT FACILITIES. Section 2.1 Term Loan Commitments. Each Lender with a Term A-1 Loan Commitment as of the Closing Date made a loan (individually, a “Term A-1 Loan” and collectively for all Lenders, the “Term A-1 Loans”) in the amount of its Term A-1 Loan Percentage as of the Closing Date of the Term A-1 Loan Commitment in U.S. Dollars to the Borrower on the Closing Date, at which time the Term A-1 Loan Commitments expired. Borrower and the Lenders acknowledge and agree that the aggregate principal balance of the Term A-1 Loans on the Third Amendment Effective Date equals $310,943,750, and the aggregate principal amount of Term A- 1 Loans held by each Lender on the Third Amendment Effective Date is as set forth opposite such Lender’s name on Schedule 1 attached hereto and made a part hereof. Subject to the terms and conditions hereof and of the Third Amendment, each Lender with a Term A-2 Loan Commitment, by its acceptance hereof and of the Third Amendment, severally agrees to make a loan (individually a “Term A-2 Loan” and collectively for all the Lenders the “Term A-2 Loans”; and together with the Term A-1 Loans, each individually a “Term Loan” and collectively for all the Lenders the “Term Loans”) in U.S. Dollars to Borrower in the amount of such Lender’s Term A-2 Loan Commitment. The Term A-2 Loans shall be advanced in a single Borrowing on the Term A-2 Loan Funding Date, at which time the Term A-2 Loan Commitments shall expire. Notwithstanding the foregoing, in the event that the Term A-2 Loan Funding Date has not occurred by the Term A-2 Loan Commitment Termination Date, the Term A-2 Loan Commitments shall automatically terminate and the Term A-2 Loan Funding Date shall not occur. As provided in Section 2.6(a), Borrower may elect that the Term Loans be outstanding as Base Rate Loans or SOFR Loans. No amount repaid or prepaid on any Term Loan may be borrowed again. Section 2.2 Revolving Credit Commitments. Subject to the terms and conditions hereof, each Lender, by its acceptance hereof, severally agrees to make a loan or loans (individually a “Revolving Loan” and collectively for all the Lenders the “Revolving Loans”) in U.S. Dollars to Borrower from time to time on a revolving basis up to the amount of such Lender’s Revolving Credit Commitment, subject to any reductions thereof pursuant to the terms hereof, before the Revolving Credit Termination Date; provided that the aggregate amount of Revolving Loans made on the Closing Date shall not exceed $30,000,000. The sum of the aggregate principal amount of Revolving Loans, Swing Loans, and L/C Obligations at any time outstanding shall not exceed the Revolving Credit Commitments in effect at such time. Each Borrowing of Revolving Loans shall be made ratably by the Lenders in proportion to their respective Revolver Percentages. As provided in Section 2.6(a), Borrower may elect that each Borrowing of Revolving Loans be either Base Rate Loans or SOFR Loans. Revolving Loans may be repaid and the principal amount thereof reborrowed before the Revolving Credit Termination Date, subject to the terms and conditions hereof. Section 2.3 Letters of Credit. (a) General Terms. Subject to the terms and conditions hereof, as part of the Revolving Credit, the L/C Issuer shall issue standby and commercial letters of credit (each a “Letter of Credit”) for the account of Borrower or for the account of Borrower and one or more of its

-36- 751970602 Subsidiaries in an aggregate undrawn face amount up to the L/C Sublimit. Each Letter of Credit shall be issued by the L/C Issuer, but each Lender shall be obligated to reimburse the L/C Issuer for such Lender’s Revolver Percentage of the amount of each drawing thereunder and, accordingly, each Letter of Credit shall constitute usage of the Revolving Credit Commitment of each Lender pro rata in an amount equal to its Revolver Percentage of the L/C Obligations then outstanding. (b) Applications. At any time before the Revolving Credit Termination Date, the L/C Issuer shall, at the request of Borrower, issue one or more Letters of Credit in U.S. Dollars, in a form satisfactory to the L/C Issuer, with expiration dates no later than the earlier of 12 months from the date of issuance (or which are cancelable not later than 12 months from the date of issuance and each renewal) or five (5) days prior to the Revolving Credit Termination Date unless Borrower shall have backstopped such Letter of Credit in a manner reasonably satisfactory to the L/C Issuer or shall have Cash Collateralized the applicable Letter of Credit, in an aggregate face amount as set forth above, upon the receipt of an application duly executed by Borrower and, if such Letter of Credit is for the account of one of its Subsidiaries, such Subsidiary for the relevant Letter of Credit in the form then customarily prescribed by the L/C Issuer for the Letter of Credit requested (each an “Application”). Notwithstanding anything contained in any Application to the contrary: (i) Borrower shall pay fees in connection with each Letter of Credit as set forth in Section 2.12, (ii) except as otherwise provided in Section 2.9 or Section 2.17, unless an Event of Default exists, the L/C Issuer will not call for the funding by Borrower of any amount under a Letter of Credit before being presented with a drawing thereunder, and (iii) if the L/C Issuer is not timely reimbursed for the amount of any drawing under a Letter of Credit on the date such drawing is paid, Borrower’s obligation to reimburse the L/C Issuer for the amount of such drawing shall bear interest (which Borrower hereby promises to pay) from and after the date such drawing is paid at a rate per annum equal to the sum of the Applicable Margin plus the Base Rate from time to time in effect (computed on the basis of a year of 365 or 366 days, as the case may be, and the actual number of days elapsed). If the L/C Issuer issues any Letter of Credit with an expiration date that is automatically extended unless the L/C Issuer gives notice that the expiration date will not so extend beyond its then scheduled expiration date, unless Administrative Agent or the Required Lenders instruct the L/C Issuer otherwise, the L/C Issuer will give such notice of non-renewal before the time necessary to prevent such automatic extension if before such required notice date: (i) the expiration date of such Letter of Credit if so extended would be after the date that is five (5) days prior to the Revolving Credit Termination Date unless Borrower shall have Cash Collateralized the applicable Letter of Credit or backstopped such Letter of Credit in a manner reasonably satisfactory to the L/C Issuer, (ii) the Revolving Credit Commitments have been terminated, or (iii) a Default or an Event of Default exists and the Required Lenders (or the Administrative Agent at their direction) have given the L/C Issuer instructions not to so permit the extension of the expiration date of such Letter of Credit. The L/C Issuer agrees to issue amendments to the Letter(s) of Credit increasing the amount, or extending the expiration date, thereof at the request of Borrower subject to the conditions of Section 4 and the other terms of this Section 2.3. Notwithstanding anything contained herein to the contrary, the L/C Issuer shall be under no obligation to issue, extend or amend any Letter of Credit if a default of any Lender’s obligations to fund under Section 2.3(c) exists or any Lender is at such time a Defaulting Lender hereunder, unless the L/C Issuer has entered into arrangements with Borrower or such Lender satisfactory to the L/C Issuer to eliminate the L/C Issuer’s risk with respect to such Lender.

-37- 751970602 (c) The Reimbursement Obligations. Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the L/C Issuer shall promptly notify the Borrower and the Administrative Agent thereof. Subject to Section 2.3(b), the obligation of Borrower to reimburse the L/C Issuer for all drawings under a Letter of Credit (a “Reimbursement Obligation”) shall be governed by the Application related to such Letter of Credit, except that reimbursement shall be made by no later than 12:00 Noon on the date when each drawing is to be paid if Borrower has been informed of such drawing by the L/C Issuer on or before 11:00 a.m. on the date when such drawing is to be paid or, if notice of such drawing is given to Borrower after 11:00 a.m. on the date when such drawing is to be paid, by no later than 12:00 Noon on the following Business Day, in immediately available funds at Administrative Agent’s principal office in Chicago, Illinois, or such other office as Administrative Agent may designate in writing to Borrower (who shall thereafter cause to be distributed to the L/C Issuer such amount(s) in like funds). If Borrower does not make any such reimbursement payment on the date due and the Participating Lenders fund their participations therein in the manner set forth in Section 2.3(e) below, then all payments thereafter received by Administrative Agent in discharge of any of the relevant Reimbursement Obligations shall be distributed in accordance with Section 2.3(e) below. (d) Obligations Absolute. Borrower’s obligation to reimburse L/C Obligations as provided in subsection (c) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement and the relevant Application under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the L/C Issuer under a Letter of Credit against presentation of a draft or other document that does not strictly comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, Borrower’s obligations hereunder. None of Administrative Agent, the Lenders, or the L/C Issuer shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the L/C Issuer; provided that the foregoing shall not be construed to excuse the L/C Issuer from liability to Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by Borrower to the extent permitted by applicable law) suffered by Borrower that are caused by the L/C Issuer’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence, bad faith or willful misconduct on the part of the L/C Issuer (as finally determined by a court of competent jurisdiction), the L/C Issuer shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the L/C Issuer may, in its sole

-38- 751970602 discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit. (e) The Participating Interests. Each Lender (other than the Lender acting as L/C Issuer in issuing the relevant Letter of Credit), by its acceptance hereof, severally agrees to purchase from the L/C Issuer, and the L/C Issuer hereby agrees to sell to each such Lender (a “Participating Lender”), an undivided percentage participating interest (a “Participating Interest”), to the extent of its Revolver Percentage, in each Letter of Credit issued by, and each Reimbursement Obligation owed to, the L/C Issuer. Upon any failure by Borrower to pay any Reimbursement Obligation at the time required on the date the related drawing is to be paid, as set forth in Section 2.3(c) above, or if the L/C Issuer is required at any time to return to Borrower or to a trustee, receiver, liquidator, custodian or other Person any portion of any payment of any Reimbursement Obligation, each Participating Lender shall, not later than the Business Day it receives a certificate in the form of Exhibit A hereto from the L/C Issuer (with a copy to Administrative Agent) to such effect, if such certificate is received before 1:00 p.m., or not later than 1:00 p.m. the following Business Day, if such certificate is received after such time, pay to Administrative Agent for the account of the L/C Issuer an amount equal to such Participating Lender’s Revolver Percentage of such unpaid or recaptured Reimbursement Obligation together with interest on such amount accrued from the date the related payment was made by the L/C Issuer to the date of such payment by such Participating Lender at a rate per annum equal to: (i) from the date the related payment was made by the L/C Issuer to the date two (2) Business Days after payment by such Participating Lender is due hereunder, the Federal Funds Rate for each such day and (ii) from the date two (2) Business Days after the date such payment is due from such Participating Lender to the date such payment is made by such Participating Lender, the Base Rate in effect for each such day. Each such Participating Lender shall thereafter be entitled to receive its Revolver Percentage of each payment received in respect of the relevant Reimbursement Obligation and of interest paid thereon, with the L/C Issuer retaining its Revolver Percentage thereof as a Lender hereunder. The several obligations of the Participating Lenders to the L/C Issuer under this Section 2.3 shall be absolute, irrevocable, and unconditional under any and all circumstances whatsoever and shall not be subject to any set off, counterclaim or defense to payment which any Participating Lender may have or have had against Borrower, the L/C Issuer, Administrative Agent, any Lender or any other Person whatsoever. Without limiting the generality of the foregoing, such obligations shall not be affected by any Default or Event of Default or by any reduction or termination of any Commitment of any Lender, and each payment by a Participating Lender under this Section 2.3 shall be made without any offset, abatement, withholding or reduction whatsoever. (f) Indemnification. The Participating Lenders shall, to the extent of their respective Revolver Percentages, indemnify the L/C Issuer (to the extent not reimbursed by Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such L/C Issuer’s gross negligence, bad faith or willful misconduct) that the L/C Issuer may suffer or incur in connection with any Letter of Credit issued by it. The obligations of the Participating Lenders under this Section 2.3(f) and all other parts of this Section 2.3 shall survive termination of this Agreement and of all Applications, Letters of Credit, and all drafts and other documents presented in connection with drawings thereunder.

-39- 751970602 (g) Manner of Requesting a Letter of Credit. Borrower shall provide at least five (5) Business Days’ advance written notice to Administrative Agent of each request for the issuance of a Letter of Credit, such notice in each case to be accompanied by an Application for such Letter of Credit properly completed and executed by Borrower and, in the case of an extension or amendment or an increase in the amount of a Letter of Credit, a written request therefor, in a form acceptable to Administrative Agent and the L/C Issuer, in each case, together with the fees called for by this Agreement. Administrative Agent shall promptly notify the L/C Issuer of Administrative Agent’s receipt of each such notice (and the L/C Issuer shall be entitled to assume that the conditions precedent to any such issuance, extension, amendment or increase have been satisfied unless notified to the contrary by Administrative Agent or the Required Lenders) and the L/C Issuer shall promptly notify Administrative Agent and the Lenders of the issuance of the Letter of Credit so requested. (h) Replacement of the L/C Issuer. The L/C Issuer may be replaced at any time by written agreement among Borrower, Administrative Agent, the replaced L/C Issuer and the successor L/C Issuer. Administrative Agent shall notify the Lenders of any such replacement of the L/C Issuer. At the time any such replacement shall become effective, Borrower shall pay all unpaid fees accrued for the account of the replaced L/C Issuer. From and after the effective date of any such replacement (i) the successor L/C Issuer shall have all the rights and obligations of the L/C Issuer under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “L/C Issuer” shall be deemed to refer to such successor or to any previous L/C Issuer, or to such successor and all previous L/C Issuers, as the context shall require. After the replacement of a L/C Issuer hereunder, the replaced L/C Issuer shall remain a party hereto and shall continue to have all the rights and obligations of a L/C Issuer under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit. Section 2.4 Applicable Interest Rates. Base Rate Loans. Each Base Rate Loan made or maintained by a Lender shall bear interest (computed on the basis of a year of 365 or 366 days, as the case may be, and the actual days elapsed) on the unpaid principal amount thereof from the date such Loan is advanced, or created by conversion from a SOFR Loan, until maturity (whether by acceleration or otherwise) at a rate per annum equal to the sum of the Applicable Margin plus the Base Rate from time to time in effect, payable by Borrower on each Interest Payment Date and at maturity (whether by acceleration or otherwise). (b) SOFR Loans. Each SOFR Loan made or maintained by a Lender shall bear interest during each Interest Period it is outstanding (computed on the basis of a year of 360 days and actual days elapsed) on the unpaid principal amount thereof from the date such Loan is advanced or continued, or created by conversion from a Base Rate Loan, until maturity (whether by acceleration or otherwise) at a rate per annum equal to the sum of the Applicable Margin plus the Adjusted Term SOFR applicable to such Interest Period, payable by Borrower on each Interest Payment Date and at maturity (whether by acceleration or otherwise). (c) Rate Determinations. Administrative Agent shall determine each interest rate applicable to the Loans and the Reimbursement Obligations hereunder, and its determination thereof shall be conclusive and binding except in the case of manifest error. In connection with the use or administration of Term SOFR, the Administrative Agent will have the right to make

-40- 751970602 Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document. The Administrative Agent will promptly notify the Borrower and the Lenders of the effectiveness of any Conforming Changes in connection with the use or administration of Term SOFR. Section 2.5 Minimum Borrowing Amounts; Maximum SOFR Loans. Each Borrowing of Base Rate Loans advanced under a Credit shall be in an amount not less than $100,000 or such greater amount which is an integral multiple of $50,000. Each Borrowing of SOFR Loans advanced, continued or converted under a Credit shall be in an amount equal to $1,000,000 or such greater amount which is an integral multiple of $500,000. Without Administrative Agent’s consent, there shall not be more than twelve (12) Borrowings of SOFR Loans outstanding hereunder at any one time. Section 2.6 Manner of Borrowing Loans and Designating Applicable Interest Rates. Notice to Administrative Agent. Borrower shall give notice to Administrative Agent by no later than 10:00 a.m.: (i) at least three (3) Business Days before the date on which Borrower requests the Lenders to advance a Borrowing of SOFR Loans and (ii) on the date Borrower requests the Lenders to advance a Borrowing of Base Rate Loans. The Loans included in each Borrowing shall bear interest initially at the type of rate specified in such notice of a new Borrowing. Thereafter, subject to the terms and conditions hereof, Borrower may from time to time elect to change or continue the type of interest rate borne by each Borrowing or, subject to the minimum amount requirement for each outstanding Borrowing set forth in Section 2.5, a portion thereof, as follows: (i) if such Borrowing is of SOFR Loans, on the last day of the Interest Period applicable thereto, Borrower may continue part or all of such Borrowing as SOFR Loans or convert part or all of such Borrowing into Base Rate Loans or (ii) if such Borrowing is of Base Rate Loans, on any Business Day, Borrower may convert all or part of such Borrowing into SOFR Loans for an Interest Period or Interest Periods specified by Borrower. Borrower shall give all such notices requesting the advance, continuation or conversion of a Borrowing to Administrative Agent by telephone, telecopy, or other telecommunication device acceptable to Administrative Agent (which notice shall be irrevocable once given and, if by telephone, shall be promptly confirmed in writing), substantially in the form attached hereto as Exhibit B (Notice of Borrowing) or Exhibit C (Notice of Continuation/Conversion), as applicable, or in such other form acceptable to Administrative Agent. Notice of the continuation of a Borrowing of SOFR Loans for an additional Interest Period or of the conversion of part or all of a Borrowing of Base Rate Loans into SOFR Loans must be given by no later than 10:00 a.m. at least three (3) Business Days before the date of the requested continuation or conversion. All such notices concerning the advance, continuation or conversion of a Borrowing shall specify the date of the requested advance, continuation or conversion of a Borrowing (which shall be a Business Day), the amount of the requested Borrowing to be advanced, continued or converted, the type of Loans to comprise such new, continued or converted Borrowing and, if such Borrowing is to be comprised of SOFR Loans, the Interest Period applicable thereto. No Borrowing of SOFR Loans shall be advanced, continued, or created by conversion if any Default or Event of Default then exists. Borrower agrees that Administrative Agent may rely on any such telephonic, telecopy or other telecommunication notice given by any person Administrative Agent in good faith believes is an Authorized Representative without the necessity of independent investigation, and in the event any such notice by telephone conflicts

-41- 751970602 with any written confirmation such telephonic notice shall govern if Administrative Agent has acted in reliance thereon. (b) Notice to the Lenders. Administrative Agent shall give prompt telephonic, telecopy or other telecommunication notice to each Lender of any notice from Borrower received pursuant to Section 2.6(a) above and the amount of such Lender’s Loan to be made as part of the requested Borrowing. (c) Borrower’s Failure to Notify. If Borrower fails to give notice pursuant to Section 2.6(a) above of the continuation or conversion of any outstanding principal amount of a Borrowing of SOFR Loans before the last day of its then current Interest Period within the period required by Section 2.6(a) and such Borrowing is not prepaid in accordance with Section 2.9(a), such Borrowing shall automatically be converted into a Borrowing of Base Rate Loans. In the event Borrower fails to give notice pursuant to Section 2.6(a) above of a Borrowing equal to the amount of a Reimbursement Obligation and has not notified Administrative Agent by 12:00 noon on the day such Reimbursement Obligation becomes due that it intends to repay such Reimbursement Obligation through funds not borrowed under this Agreement, Borrower shall be deemed to have requested a Borrowing of Base Rate Loans under the Revolving Credit (or, at the option of the Swing Line Lender, under the Swing Line) on such day in the amount of the Reimbursement Obligation then due, which Borrowing shall be applied to pay the Reimbursement Obligation then due. (d) Disbursement of Loans. Not later than 1:00 p.m. on the date of any requested advance of a new Borrowing, subject to Section 4, each Lender shall make available its Loan comprising part of such Borrowing in funds immediately available at the principal office of Administrative Agent in Chicago, Illinois (or at such other location as Administrative Agent shall designate). Administrative Agent shall make the proceeds of each new Borrowing available to Borrower at Administrative Agent’s principal office in Chicago, Illinois (or at such other location as Administrative Agent shall designate), by depositing or wire transferring such proceeds to the credit of Borrower’s Designated Disbursement Account or as Borrower and Administrative Agent may otherwise agree. (e) Administrative Agent Reliance on Lender Funding. Unless Administrative Agent shall have been notified by a Lender prior to (or, in the case of a Borrowing of Base Rate Loans, by 1:00 p.m. on the date on which such Lender is scheduled to make payment to Administrative Agent of the proceeds of a Loan (which notice shall be effective upon receipt) that such Lender does not intend to make such payment, Administrative Agent may assume that such Lender has made such payment when due and Administrative Agent may (but shall not be required to) in reliance upon such assumption make available to Borrower the proceeds of the Loan to be made by such Lender and, if any Lender has not in fact made such payment to Administrative Agent, such Lender shall, on demand, pay to Administrative Agent the amount made available to Borrower attributable to such Lender together with interest thereon in respect of each day during the period commencing on the date such amount was made available to Borrower and ending on (but excluding) the date such Lender pays such amount to Administrative Agent at a rate per annum equal to: (i) from the date the related advance was made by Administrative Agent to the date two (2) Business Days after payment by such Lender is due hereunder, the Federal Funds Rate for each such day and (ii) from the date two (2) Business Days after the date such payment is due from such

-42- 751970602 Lender to the date such payment is made by such Lender, the Base Rate in effect for each such day. If such amount is not received from such Lender by Administrative Agent immediately upon demand, Borrower will, on demand, repay to Administrative Agent the proceeds of the Loan attributable to such Lender with interest thereon at a rate per annum equal to the interest rate applicable to the relevant Loan, but without such payment being considered a payment or prepayment of a Loan under Section 3.3 so that Borrower will have no liability under such Section with respect to such payment. Section 2.7 Swing Loans. Generally. Subject to the terms and conditions hereof, as part of the Revolving Credit, the Swing Line Lender may, in its discretion, make loans in U.S. Dollars to Borrower under the Swing Line (individually a “Swing Loan” and collectively the “Swing Loans”) which shall not in the aggregate at any time outstanding exceed the Swing Line Sublimit. Swing Loans may be availed of from time to time and borrowings thereunder may be repaid and used again during the period ending on the Revolving Credit Termination Date. Each Swing Loan shall be in a minimum amount of $250,000 or such greater amount which is an integral multiple of $100,000. (b) Interest on Swing Loans. Each Swing Loan shall bear interest until maturity (whether by acceleration or otherwise) at a rate per annum equal to (i) the sum of the Base Rate plus the Applicable Margin for Base Rate Loans under the Revolving Credit as from time to time in effect (computed on the basis of a year of 365 or 366 days, as the case may be, for the actual number of days elapsed) or (ii) the Swing Line Lender’s Quoted Rate (computed on the basis of a year of 360 days for the actual number of days elapsed). Interest on each Swing Loan shall be due and payable by Borrower on each Interest Payment Date and at maturity (whether by acceleration or otherwise). (c) Requests for Swing Loans. Borrower shall give Administrative Agent prior notice (which may be written or oral) no later than 12:00 Noon on the date upon which Borrower requests that any Swing Loan be made, of the amount and date of such Swing Loan, and, if applicable, the Interest Period requested therefor. Administrative Agent shall promptly advise the Swing Line Lender of any such notice received from Borrower. After receiving such notice, the Swing Line Lender shall in its discretion quote an interest rate to Borrower at which the Swing Line Lender would be willing to make such Swing Loan available to Borrower for the Interest Period so requested (the rate so quoted for a given Interest Period being herein referred to as “Swing Line Lender’s Quoted Rate”). Borrower acknowledges and agrees that the interest rate quote is given for immediate and irrevocable acceptance. If Borrower does not so immediately accept the Swing Line Lender’s Quoted Rate for the full amount requested by Borrower for such Swing Loan, the Swing Line Lender’s Quoted Rate shall be deemed immediately withdrawn and such Swing Loan shall bear interest at the rate per annum determined by adding the Applicable Margin for Base Rate Loans under the Revolving Credit to the Base Rate as from time to time in effect. Subject to the terms and conditions hereof, the proceeds of each Swing Loan extended to Borrower shall be deposited or otherwise wire transferred to Borrower’s Designated Disbursement Account or as Borrower, Administrative Agent, and the Swing Line Lender may otherwise agree. Anything contained in the foregoing to the contrary notwithstanding, the undertaking of the Swing Line Lender to make Swing Loans shall be subject to all of the terms and conditions of this Agreement (provided that the Swing Line Lender shall be entitled to assume that the conditions precedent to

-43- 751970602 an advance of any Swing Loan have been satisfied unless notified to the contrary by Administrative Agent or the Required Lenders). (d) Refunding Loans. In its sole and absolute discretion, the Swing Line Lender may at any time, on behalf of Borrower (which hereby irrevocably authorizes the Swing Line Lender to act on its behalf for such purpose) and with notice to Borrower and Administrative Agent, request each Lender to make a Revolving Loan in the form of a Base Rate Loan in an amount equal to such Lender’s Revolver Percentage of the amount of the Swing Loans outstanding on the date such notice is given. Unless an Event of Default described in Section 8.1(j) or 8.1(k) exists with respect to Borrower, regardless of the existence of any other Event of Default, each Lender shall make the proceeds of its requested Revolving Loan available to Administrative Agent for the account of the Swing Line Lender), in immediately available funds, at Administrative Agent’s office in Chicago, Illinois (or such other location designated by Administrative Agent), before 12:00 Noon on the Business Day following the day such notice is given. Administrative Agent shall promptly remit the proceeds of such Borrowing to the Swing Line Lender to repay the outstanding Swing Loans. (e) Participations. If any Lender refuses or otherwise fails to make a Revolving Loan when requested by the Swing Line Lender pursuant to Section 2.7(d) (because an Event of Default described in Section 8.1(j) or 8.1(k) exists with respect to Borrower or otherwise), such Lender will, by the time and in the manner such Revolving Loan was to have been funded to the Swing Line Lender, purchase from the Swing Line Lender an undivided participating interest in the outstanding Swing Loans in an amount equal to its Revolver Percentage of the aggregate principal amount of Swing Loans that were to have been repaid with such Revolving Loans. Each Lender that so purchases a participation in a Swing Loan shall thereafter be entitled to receive its Revolver Percentage of each payment of principal received on the Swing Loan and of interest received thereon accruing from the date such Lender funded to the Swing Line Lender its participation in such Loan. The several obligations of the Lenders under this Section shall be absolute, irrevocable, and unconditional under any and all circumstances whatsoever and shall not be subject to any set off, counterclaim or defense to payment which any Lender may have or have had against Borrower, any other Lender, or any other Person whatsoever. Without limiting the generality of the foregoing, such obligations shall not be affected by any Default or Event of Default or by any reduction or termination of the Commitments of any Lender, and each payment made by a Lender under this Section shall be made without any offset, abatement, withholding, or reduction whatsoever.

All voluntary prepayments of Term A-1 Loans and Term A-2 Loans shall be applied to the Lenders holding such Term Loans on a pro rata basis. (b) Mandatory Prepayments. (i) Borrower or any Subsidiary or Project Specific JV shall at any time or from time to time make or agree to make a Disposition or shall suffer an Event of Loss with respect to any Property (except that with respect to any Affiliated Entity or Project Specific JV constituting, in either case, an Excluded Subsidiary, only to the extent of the Net Cash Proceeds received by the Loan Parties), then Borrower shall promptly notify Administrative Agent of such proposed Disposition or Event of Loss (including the amount of the estimated Net Cash Proceeds to be received by Borrower or such Subsidiary in respect thereof) and, promptly upon receipt by Borrower or such Subsidiary of the Net Cash Proceeds of such Disposition or Event of Loss, Borrower shall prepay the Obligations in an aggregate amount equal to 100% of the amount of all such Net Cash Proceeds; provided that (x) this subsection shall not require any such prepayment with respect to Net Cash Proceeds received on account of Dispositions during any fiscal year of Borrower not exceeding $2,500,000 in the aggregate or any Events of Loss during any fiscal year of Borrower not exceeding $2,500,000 in the aggregate, in each case so long as no Default or Event of Default then exists, and (y) in the case of any Disposition or Event of Loss not covered by clause (x) above, so long as no Default or Event of Default then exists, if Borrower states in its notice of such event that Borrower or the relevant Subsidiary intends to reinvest, within 360 days of the date of receipt thereof, the Net Cash Proceeds thereof in assets useful to the business of the Borrower and its Subsidiaries, then Borrower shall not

-46- 751970602 be required to make a mandatory prepayment under this subsection in respect of such Net Cash Proceeds to the extent such Net Cash Proceeds are actually so reinvested within such 360 day period; provided that if Borrower or any relevant Subsidiary shall have contractually committed to so reinvest such Net Cash Proceeds within such 360-day period, such period for reinvestment shall be extended for an additional 180 days. Promptly after the end of such reinvestment period, Borrower shall notify Administrative Agent whether Borrower or such Subsidiary has reinvested such Net Cash Proceeds in such similar assets, and, to the extent such Net Cash Proceeds have not been so reinvested, Borrower shall promptly prepay the Obligations in the amount of such Net Cash Proceeds not so reinvested. The amount of each such prepayment shall be applied, subject to Section 2.9(b)(vi), first to the outstanding Term Loans until paid in full and then to the Revolving Credit (with no reduction of Revolving Credit Commitments). If Administrative Agent or the Required Lenders so request, all proceeds of such Disposition or Event of Loss shall be deposited with Administrative Agent (or its agent) and held by it in the Collateral Account. So long as no Default or Event of Default exists, Administrative Agent is authorized to disburse amounts representing such proceeds from the Collateral Account to or at Borrower’s direction for application to or reimbursement for the costs of replacing, rebuilding or restoring such Property. (ii) If, after the Closing Date, Borrower or any Subsidiary (except that with respect to any Affiliated Entity or Project Specific JV constituting, in either case, an Excluded Subsidiary, only to the extent of the Net Cash Proceeds received by the Loan Parties) shall issue any Indebtedness for Borrowed Money not permitted by Section 7.1 (other than Section 7.1(o), except to the extent contemplated by clause (v) thereof)), Borrower shall promptly notify Administrative Agent of the estimated Net Cash Proceeds of such issuance to be received by or for the account of Borrower or such Subsidiary in respect thereof. Promptly upon receipt by Borrower or such Subsidiary of Net Cash Proceeds of such issuance, Borrower shall prepay the Obligations in an aggregate amount equal to 100% of the amount of such Net Cash Proceeds. The amount of each such prepayment shall be applied, subject to Section 2.9(b)(vi), first to the outstanding Term Loans until paid in full and then to the Revolving Credit; provided that each Lender holding Term Loans shall have the right to elect, by notice to the Administrative Agent at or prior to the time and in the manner specified by the Administrative Agent, to decline all or a portion of its pro rata share of any prepayment pursuant this clause (ii) (such declined amounts, the “Declined Proceeds”), in which case such Declined Proceeds shall be applied on a pro rata basis to the Term Loans of Lenders which did not decline to receive their pro rata share of such prepayment until paid in full and then to the Revolving Credit. Borrower acknowledges that its performance hereunder shall not limit the rights and remedies of the Lenders for any breach of Section 7.1 or any other terms of the Loan Documents. (iii) Within five (5) days after receipt of Borrower’s year end audited financial statements, and in any event within 125 days after the end of each fiscal year of Borrower (commencing with the fiscal year ending December 31, 2022), Borrower shall prepay the Obligations by an amount equal to (x) the ECF Percentage of Excess Cash Flow of Borrower and its Subsidiaries for such fiscal year minus (y) the aggregate amount of voluntary prepayments of Loans hereunder (in the case of the Revolving Credit, to the extent accompanied by a reduction of Revolving Credit Commitments) during such fiscal

-47- 751970602 year or after year-end and prior to the date such Excess Cash Flow prepayment is due (without duplication of any amounts deducted pursuant to this clause (y) in the prior fiscal year). The amount of each such prepayment shall be applied, subject to Section 2.9(b)(vi), first to the outstanding Term Loans until paid in full and then to the Revolving Credit. (iv) Borrower shall, on each date the Revolving Credit Commitments are reduced pursuant to Section 2.15, prepay the Revolving Loans, Swing Loans, and, if necessary, prefund the L/C Obligations by the amount, if any, necessary to reduce the sum of the aggregate principal amount of Revolving Loans, Swing Loans, and L/C Obligations then outstanding to the amount to which the Revolving Credit Commitments have been so reduced. (v) If at any time the sum of the unpaid principal balance of the Revolving Loans, Swing Loans, and the L/C Obligations then outstanding shall be in excess of the Revolving Credit Commitment, Borrower shall immediately and without notice or demand pay over the amount of the excess to Administrative Agent for the account of the Lenders as and for a mandatory prepayment on such Obligations, with each such prepayment first to be applied to the Revolving Loans and Swing Loans until paid in full with any remaining balance to be held by Administrative Agent in the Collateral Account as security for the Obligations owing with respect to the Letters of Credit. (vi) Unless Borrower otherwise directs, prepayments of Loans under this Section 2.9(b) shall be applied first to Borrowings of Base Rate Loans until payment in full thereof with any balance applied to Borrowings of SOFR Loans in the order in which their Interest Periods expire. Each prepayment of Loans under this Section 2.9(b) shall be made by the payment of the principal amount to be prepaid and, in the case of any Term Loans or SOFR Loans or Swing Loans, accrued interest thereon to the date of prepayment together with any amounts due the Lenders under Section 3.3. Each prefunding of L/C Obligations shall be made in accordance with Section 8.4. (c) Any amount of Revolving Loans and Swing Loans paid or prepaid before the Revolving Credit Termination Date may, subject to the terms and conditions of this Agreement, be borrowed, repaid and borrowed again. No amount of the Term Loans paid or prepaid may be reborrowed, and, in the case of any partial prepayment, such prepayment shall be applied to the remaining amortization payments, including the payment due on the Term Loan Maturity Date, on the relevant Term Loans on a ratable, weighted basis among all such remaining payments based on the principal amounts thereof. Section 2.10 Default Rate. Notwithstanding anything to the contrary contained herein, while any Event of Default exists or after acceleration, Borrower shall pay interest (after as well as before entry of judgment thereon to the extent permitted by law) on the principal amount of all Loans and Reimbursement Obligations, letter of credit fees and interest on any other amounts owing hereunder or under the other Loan Documents at a rate per annum equal to: (a) for any Base Rate Loan or any Swing Loan bearing interest based on the Base Rate, the sum of 2.0% plus the Applicable Margin plus the Base Rate from time to time in effect;

-48- 751970602 (b) for any SOFR Loan or any Swing Loan bearing interest at Adjusted Term SOFR or the Swing Line Lender’s Quoted Rate, as applicable, the sum of 2.0% plus the rate of interest in effect thereon at the time of such default until the end of the Interest Period applicable thereto and, thereafter, at a rate per annum equal to the sum of 2.0% plus the Applicable Margin for Base Rate Loans plus the Base Rate from time to time in effect; (c) for any Reimbursement Obligation, the sum of 2.0% plus the amounts due under Section 2.3 with respect to such Reimbursement Obligation; (d) for any Letter of Credit, the sum of 2.0% plus the letter of credit fee due under Section 2.12 with respect to such Letter of Credit; and (e) for any other overdue amounts, the sum of 2.0% plus the Applicable Margin plus the Base Rate from time to time in effect; provided, that in the absence of acceleration, any adjustments pursuant to this Section shall be made at the election of Administrative Agent, acting at the request or with the consent of the Required Lenders, with written notice to Borrower. While any Event of Default exists or after acceleration, interest shall be paid on demand of Administrative Agent at the request or with the consent of the Required Lenders. Section 2.11 Evidence of Indebtedness. Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. (b) Administrative Agent shall also maintain accounts in which it will record (i) the amount of each Loan made hereunder, the type thereof and the Interest Period with respect thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from Borrower to each Lender hereunder and (iii) the amount of any sum received by Administrative Agent hereunder from Borrower and each Lender’s share thereof. (c) The entries maintained in the accounts maintained pursuant to paragraphs (a) and (b) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded; provided, that the failure of Administrative Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of Borrower to repay the Obligations in accordance with their terms. (d) Any Lender may request that its Loans be evidenced by a promissory note or notes in the forms of Exhibit D-1 (in the case of its Term Loan and referred to herein as a “Term Note”), Exhibit D-2 (in the case of its Revolving Loans and referred to herein as a “Revolving Note”), or Exhibit D-3 (in the case of its Swing Loans and referred to herein as a “Swing Note”), as applicable (the Term Notes, Revolving Notes, and Swing Note being hereinafter referred to collectively as the “Notes” and individually as a “Note”). In such event, Borrower shall prepare, execute and deliver to such Lender a Note payable to such Lender or its registered assigns in the amount of the relevant Term Loan, Commitment, or Swing Line Sublimit, as applicable. Thereafter, the Loans evidenced by such Note or Notes and interest thereon shall at all times (including after any assignment pursuant to Section 11.10) be represented by one or more Notes payable to the order

-49- 751970602 of the payee named therein or any assignee pursuant to Section 11.10, except to the extent that any such Lender or assignee subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in subsections (a) and (b) above. Section 2.12 Fees. (a) Revolving Credit Commitment Fee. Borrower shall pay to Administrative Agent for the ratable account of the Lenders in accordance with their Revolver Percentages a commitment fee at the rate per annum equal to the Applicable Margin (computed on the basis of a year of 360 days and the actual number of days elapsed) on the average daily Unused Revolving Credit Commitments. Such commitment fee shall be payable quarterly in arrears on the last day of each March, June, September, and December in each year (commencing on the first such date occurring after the date hereof) and on the Revolving Credit Termination Date, unless the Revolving Credit Commitments are terminated in whole on an earlier date, in which event the commitment fee for the period to the date of such termination in whole shall be paid on the date of such termination. (b) Letter of Credit Fees. On the date of issuance or extension, or increase in the amount, of any Letter of Credit pursuant to Section 2.3 hereof, Borrower shall pay to the L/C Issuer for its own account a fronting fee equal to 0.125% of the face amount of (or of the increase in the face amount of) such Letter of Credit. Quarterly in arrears, on the last day of each March, June, September, and December, commencing on the first such date occurring after the date hereof, Borrower shall pay to Administrative Agent, for the ratable benefit of the Lenders in accordance with their Revolver Percentages, a letter of credit fee at a rate per annum equal to the Applicable Margin (computed on the basis of a year of 360 days and the actual number of days elapsed) in effect during each day of such quarter applied to the daily average face amount of Letters of Credit outstanding during such quarter. In addition, Borrower shall pay to the L/C Issuer for its own account the L/C Issuer’s standard issuance, drawing, negotiation, amendment, assignment, and other fees and charges for each Letter of Credit as established by the L/C Issuer from time to time. (c) Administrative Agent Fees. Borrower shall pay to Administrative Agent, for its own use and benefit, the fees agreed to between Administrative Agent and Borrower in a fee letter dated as of the Closing Date, or as otherwise agreed to in writing between them. (d) Audit Fees. Borrower shall pay to Administrative Agent for its own use and benefit charges for audits of the Collateral performed by Administrative Agent or its agents or representatives in such amounts as Administrative Agent may from time to time request (Administrative Agent acknowledging and agreeing that such charges shall be computed in the same manner as it at the time customarily uses for the assessment of charges for similar collateral audits); provided, that in the absence of any Default or Event of Default, Borrower shall not be required to pay Administrative Agent for more than one (1) such audit per calendar year. Section 2.13 Place and Application of Payments. All payments of principal of and interest on the Loans and the Reimbursement Obligations, and of all other Obligations payable by Borrower under this Agreement and the other Loan Documents, shall be made by Borrower to Administrative Agent by no later than 12:00 Noon on the due date thereof at the office of Administrative Agent in Chicago, Illinois (or such other location as Administrative Agent may designate to Borrower), for the benefit of the Lender(s) or L/C Issuer entitled thereto. Any

-50- 751970602 payments received after such time shall be deemed to have been received by Administrative Agent on the next Business Day. All such payments shall be made in U.S. Dollars, in immediately available funds at the place of payment, in each case without set off or counterclaim. Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest on Loans and on Reimbursement Obligations in which the Lenders have purchased Participating Interests ratably to the Lenders and like funds relating to the payment of any other amount payable to any Lender to such Lender, in each case to be applied in accordance with the terms of this Agreement. Unless Administrative Agent shall have received notice from Borrower prior to the date on which any payment is due to Administrative Agent for the account of the Lenders or the L/C Issuer hereunder that Borrower will not make such payment, Administrative Agent may assume that Borrower has made such payment on such date in accordance herewith and may (but shall not be required to) in reliance upon such assumption, distribute to the applicable Lenders or the L/C Issuer, as the case may be, the amount due. With respect to any payment that Administrative Agent makes to any Lender, L/C Issuer or other Secured Party as to which Administrative Agent determines (in its sole and absolute discretion) that any of the following applies (such payment referred to as the “Rescindable Amount”): (1) Borrower has not in fact made the corresponding payment to Administrative Agent; (2) Administrative Agent has made a payment in excess of the amount(s) received by it from Borrower either individually or in the aggregate (whether or not then owed); or (3) Administrative Agent has for any reason otherwise erroneously made such payment; then each of the Secured Parties severally agrees to repay to Administrative Agent forthwith on demand the Rescindable Amount so distributed to such Secured Party, in immediately available funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by Administrative Agent in accordance with banking industry rules on interbank compensation. Anything contained herein to the contrary notwithstanding (including Section 2.9(b)), all payments and collections received in respect of the Obligations and all proceeds of the Collateral received, in each instance, by Administrative Agent or any of the Lenders after acceleration or the final maturity of the Obligations or termination of the Commitments as a result of an Event of Default shall be remitted to Administrative Agent and distributed as follows: (a) first, to the payment of any outstanding costs and expenses incurred by Administrative Agent, and any security trustee therefor, in monitoring, verifying, protecting, preserving or enforcing the Liens on the Collateral, in protecting, preserving or enforcing rights under the Loan Documents, and in any event including all costs and expenses of a character which Borrower has agreed to pay Administrative Agent under Section 11.13 (such funds to be retained by Administrative Agent for its own account unless it has previously been reimbursed for such costs and expenses by the Lenders, in which event such amounts shall be remitted to the Lenders to reimburse them for payments theretofore made to Administrative Agent); (b) second, to the payment of the Swing Loans, both for principal and accrued but unpaid interest; (c) third, to the payment of any outstanding interest and fees due under the Loan Documents to be allocated pro rata in accordance with the aggregate unpaid amounts owing to each holder thereof;

-51- 751970602 (d) fourth, to the payment of principal on the Loans (other than Swing Loans), unpaid Reimbursement Obligations, together with amounts to be held by Administrative Agent as collateral security for any outstanding L/C Obligations pursuant to Section 8.4 (until Administrative Agent is holding an amount of cash equal to the then outstanding amount of all such L/C Obligations), Funds Transfer and Deposit Account Liability and Hedging Liability (provided that funds from, and proceeds of Collateral owned by, any Person directly or indirectly liable for a Swap Obligation and that was not an “eligible contract participant” as defined in the Commodity Exchange Act at the time such Swap Obligation was incurred may not be used to satisfy such Swap Obligation), the aggregate amount paid to, or held as collateral security for, the Lenders and L/C Issuer and, in the case of Hedging Liability, their Affiliates (and any Person that was a Lender or an Affiliate of a Lender at the time of the entering into such agreement or arrangement) to be allocated pro rata in accordance with the aggregate unpaid amounts owing to each holder thereof; (e) fifth, to the payment of all other unpaid Obligations and all other indebtedness, obligations, and liabilities of Borrower and its Subsidiaries secured by the Loan Documents (provided that funds from, and proceeds of Collateral owned by, any Person directly or indirectly liable for a Swap Obligation and that was not an “eligible contract participant” as defined in the Commodity Exchange Act at the time such Swap Obligation was incurred may not be used to satisfy such Swap Obligation) to be allocated pro rata in accordance with the aggregate unpaid amounts owing to each holder thereof; and (f) finally, to Borrower or whoever else may be lawfully entitled thereto. Section 2.14 Account Debit. Borrower hereby irrevocably authorizes Administrative Agent to charge any of Borrower’s deposit accounts maintained with Administrative Agent for the amounts from time to time necessary to pay any then due Obligations; provided that Borrower acknowledges and agrees that Administrative Agent shall not be under an obligation to do so and Administrative Agent shall not incur any liability to Borrower or any other Person for Administrative Agent’s failure to do so. Section 2.15 Commitment Terminations. Borrower shall have the right at any time and from time to time, upon three (3) Business Days’ prior written notice to Administrative Agent (or such shorter period of time agreed to by Administrative Agent), to terminate the Revolving Credit Commitments without premium or penalty and in whole or in part, any partial termination to be (i) in an amount of than $5,000,000 or any increment of $5,000,000 thereof and (ii) allocated ratably among the Lenders in proportion to their respective Revolver Percentages, provided that the Revolving Credit Commitments may not be reduced to an amount less than the sum of the aggregate principal amount of Revolving Loans, Swing Loans, and L/C Obligations then outstanding. Any termination of the Revolving Credit Commitments below the L/C Sublimit or the Swing Line Sublimit then in effect shall reduce the L/C Sublimit and Swing Line Sublimit, as applicable, by a like amount. Administrative Agent shall give prompt notice to each Lender of any such termination of the Revolving Credit Commitments. (b) Any termination of the Commitments pursuant to this Section 2.15 may not be reinstated.

-52- 751970602 Section 2.16 Substitution of Lenders. In the event (a) Borrower receives a claim from any Lender for compensation under Section 3.6 or 3.1, (b) Borrower receives notice from any Lender of any illegality pursuant to Section 3.4, (c) any Lender is then a Defaulting Lender or such Lender is a Subsidiary or Affiliate of a Person who has been deemed insolvent or becomes the subject of a bankruptcy or insolvency proceeding or a receiver or conservator has been appointed for any such Person, or (d) a Lender fails to consent to an amendment or waiver requested under Section 11.11 at a time when the Required Lenders have approved such amendment or waiver (any such Lender referred to in clause (a), (b), (c), or (d) above being hereinafter referred to as an “Affected Lender”), Borrower may, in addition to any other rights Borrower may have hereunder or under applicable law, require, at its expense, any such Affected Lender to assign, at par, without recourse, all of its interest, rights, and obligations hereunder (including all of its Commitments and the Loans and participation interests in Letters of Credit and other amounts at any time owing to it hereunder and the other Loan Documents) to an Eligible Assignee specified by Borrower, provided that (i) such assignment shall not conflict with or violate any law, rule or regulation or order of any court or other Governmental Authority, (ii) Borrower shall have paid to the Affected Lender all monies (together with amounts due such Affected Lender under Section 3.3 as if the Loans owing to it were prepaid rather than assigned) other than such principal owing to it hereunder, and (iii) the assignment is entered into in accordance with, and subject to the consents required by, Section 11.10 (provided any assignment fees and reimbursable expenses due thereunder shall be paid by Borrower). Section 2.17 Defaulting Lenders. Anything contained herein to the contrary notwithstanding, in the event that any Lender at any time is a Defaulting Lender, then (a) during any Defaulting Lender Period with respect to such Defaulting Lender, such Defaulting Lender shall be deemed not to be a “Lender” for purposes of voting on any matters (including the granting of any consents or waivers) with respect to any of the Loan Documents and such Defaulting Lender’s Commitments shall be excluded for purposes of determining “Required Lenders” (provided that the foregoing shall not permit an increase in such Lender’s Commitments or an extension of the maturity date of such Lender’s Loans or other Obligations without such Lender’s consent); (b) to the extent permitted by applicable law, until such time as the Defaulting Lender Excess with respect to such Defaulting Lender shall have been reduced to zero, any voluntary prepayment of the Loans shall, if Administrative Agent so directs at the time of making such voluntary prepayment, be applied to the Loans of other Lenders as if such Defaulting Lender had no Loans outstanding; (c) such Defaulting Lender’s Commitments and outstanding Loans shall be excluded for purposes of calculating any commitment fee payable to Lenders pursuant to Section 2.12 in respect of any day during any Defaulting Lender Period with respect to such Defaulting Lender, and such Defaulting Lender shall not be entitled to receive any fee pursuant to Section 2.12 with respect to such Defaulting Lender’s Commitment in respect of any Defaulting Lender Period with respect to such Defaulting Lender (and any Letter of Credit fee otherwise payable to a Lender who is a Defaulting Lender shall instead be paid to the L/C Issuer for its use and benefit); (d) the utilization of Commitments as at any date of determination shall be calculated as if such Defaulting Lender had funded all Loans of such Defaulting Lender; and (e) if so requested by the L/C Issuer at any time during the Defaulting Lender Period with respect to such Defaulting Lender, Borrower shall deliver to Administrative Agent cash collateral in an amount equal to such Defaulting Lender’s Percentage of L/C Obligations then outstanding (to be, held by Administrative Agent as set forth in Section 8.4). No Commitment of any Lender shall be increased or otherwise affected, and, except as otherwise expressly provided in this Section 2.17, performance by

-53- 751970602 Borrower of its obligations hereunder and the other Loan Documents shall not be excused or otherwise modified as a result of the operation of this Section 2.17. The rights and remedies against a Defaulting Lender under this Section 2.17 are in addition to other rights and remedies which Borrower may have against such Defaulting Lender and which Administrative Agent or any Lender may have against such Defaulting Lender. Section 2.18 Incremental Loans. (a) Borrower may from time to time, on not less than five (5) Business Days’ notice request the establishment of (x) one or more term loan commitments, which may be in the form of a new tranche of term loans or an increase in the amount of the Term Loans (such new term loan commitments or increase, the “New Term Loan Commitments”) or (y) one or more revolving loan commitments, which shall be an increase in the amount of the Revolving Credit Commitments (such increased commitments, the “New Revolving Loan Commitments” and together with the New Term Loan Commitments, the “New Loan Commitments”), provided, in each case, that at the time of any such request and on the date the New Loan Commitments shall be effective (the “Increased Amount Date”) (and after giving effect thereto and the use of the proceeds thereof), (i) no Default or Event of Default exists and (ii) Borrower shall have a (A) Total Leverage Ratio (on a pro forma basis as of the most recently completed calendar quarter for which financial statements have been prepared and finalized by Borrower) of less than the lesser of 3.00 to 1.00 and 0.25 to 1.00 less than the applicable covenant level and (B) Senior Secured Leverage Ratio (on a pro forma basis as of the most recently completed calendar quarter for which financial statements have been prepared and finalized by Borrower) of less than 2.50 to 1.00. Each New Loan Commitment shall be in an aggregate principal amount of at least $10,000,000 and in integral multiples of at least $5,000,000 and the aggregate principal amount of all New Loan Commitments after the Third Amendment Effective Date (and excluding for the avoidance of doubt the Term A- 2 Loan Commitments) shall not exceed $100,000,000.Each request for a New Loan Commitment shall set forth the requested amount and proposed terms of the relevant New Loan Commitment and the Lenders or other Persons willing to provide such New Loan Commitments. New Loan Commitments may be made by any existing Lender or if necessary to achieve the full amount of the requested New Loan Commitment, any other Person that qualifies as an Eligible Assignee (any such Person, an “New Lender”), provided that no Person shall be a New Lender without the consent of Administrative Agent (which consent shall not be unreasonably withheld). (c) The making of any Loan under this Section 2.18 (a “New Term Loan” or a “New Revolving Loan”, as applicable, and collectively, the “New Loans”) shall (i) be subject to each condition set forth in Section 4.2 and such other conditions as Borrower, the applicable Lenders and Administrative Agent shall agree (including delivery of any legal opinions or other documents reasonably requested by Administrative Agent in connection with any such transaction); and (ii) be documented pursuant to a supplement or joinder to this Agreement executed by Borrower, each applicable New Lender and Administrative Agent. Any New Loan Commitments shall be designated in the applicable supplement or joinder either as a separate tranche (in the case of term loans) or an increase to the existing Term Loans or Revolving Credit Commitments, as applicable (in each case a “Tranche”), for all purposes of this Agreement. (d) The terms and provisions of the New Loans and New Loan Commitments shall, except as otherwise set forth herein or in the applicable supplement, be identical to those applicable

-54- 751970602 to the Term Loans or Revolving Loans, as the case may be. In any event, (i) such New Loans shall (x) rank pari passu in right of payment and of security with all other Loans and (y) in the case of New Term Loans, be entitled to share in prepayments pro rata with the other Term Loans (unless the applicable New Term Lenders agree to take a lesser share of certain prepayments), (ii) with respect to each New Term Loan, the weighted average life to maturity of all New Term Loans shall be no shorter than the weighted average life to maturity of any existing Term Loans, (iii) with respect to any New Term Loan, the maturity date for any New Term Loan shall not be earlier than the maturity date with respect to the Term Loans, as applicable, (iv) the amortization schedule applicable to any Tranche of New Loans shall be determined by Borrower and the applicable New Lenders, (v) the interest rates, fees (including any original issue discount), other pricing-related provisions and yield applicable to any New Loans shall be determined by Borrower and the applicable New Lenders and shall be set forth in each applicable supplement; provided that the All-in Yield for any New Term Loans shall not be more than 0.50% higher than the All-in Yield for any Term Loans outstanding on the date of the issuance of such New Term Loans unless the interest rate on such outstanding Term Loans is increased so that the All-in Yield on such outstanding Term Loans is not less than the All-in Yield for the New Term Loans minus 0.50%, and (vi) will constitute “Senior Debt” or similar terms under and as such terms of defined in each Subordination Agreement. Notwithstanding anything to the contrary in Section 11.11, each applicable supplement or joinder may, without the consent of any other Lender, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the opinion of Administrative Agent, to effect the provisions of this Section 2.18. (e) On each Increased Amount Date, each New Lender with a New Revolving Loan Commitment shall make a Revolving Loan to Borrower the proceeds of which will be used to prepay the Revolving Loans of the other Lenders immediately prior to such Increased Amount Date, so that, after giving effect thereto and to any other borrowings and prepayments being made on such date, the Revolving Loans outstanding are held by the Lenders pro rata based on their Revolving Credit Commitments after giving effect to such Increased Amount Date. SECTION 3. TAXES; CHANGE IN CIRCUMSTANCES. Section 3.1 Withholding Taxes. (a) Payments Free of Withholding. Except as otherwise required by law and subject to Section 3.1(b), each payment by Borrower and the Guarantors under this Agreement or the other Loan Documents shall be made without withholding for or on account of any present or future taxes (other than overall net income taxes on the recipient) imposed by or within the jurisdiction in which Borrower or such Guarantor is domiciled, any jurisdiction from which Borrower or such Guarantor makes any payment, or (in each case) any political subdivision or taxing authority thereof or therein. If any such withholding is so required, Borrower or such Guarantor shall make the withholding, pay the amount withheld to the appropriate Governmental Authority before penalties attach thereto or interest accrues thereon, and forthwith pay such additional amount as may be necessary to ensure that the net amount actually received by each Lender, the L/C Issuer, and Administrative Agent free and clear of such taxes (including such taxes on such additional amount) is equal to the amount which that Lender, L/C Issuer, or Administrative Agent (as the case may be) would have received had such withholding not been made. If Administrative Agent, the L/C Issuer, or any Lender pays any amount in respect of any such taxes, penalties or interest,

-55- 751970602 Borrower or such Guarantor shall reimburse Administrative Agent, the L/C Issuer or such Lender for that payment on demand in the currency in which such payment was made. If Borrower or such Guarantor pays any such taxes, penalties or interest, it shall deliver official tax receipts evidencing that payment or certified copies thereof to the Lender, the L/C Issuer or Administrative Agent on whose account such withholding was made (with a copy to Administrative Agent if not the recipient of the original) on or before the thirtieth day after payment. (b) U.S. Withholding Tax Exemptions. Each Lender or L/C Issuer that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) shall submit to Borrower and Administrative Agent on or before the date the initial Credit Event is made hereunder or, if later, the date such financial institution becomes a Lender or L/C Issuer hereunder, two duly completed and signed copies of (i) either Form W 8 BEN (relating to such Lender or L/C Issuer and entitling it to a complete exemption from withholding under the Code on all amounts to be received by such Lender or L/C Issuer, including fees, pursuant to the Loan Documents and the Obligations) or Form W 8 ECI (relating to all amounts to be received by such Lender or L/C Issuer, including fees, pursuant to the Loan Documents and the Obligations) of the United States Internal Revenue Service or (ii) solely if such Lender is claiming exemption from United States withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, a Form W 8 BEN, or any successor form prescribed by the Internal Revenue Service, and a certificate representing that such Lender is not a bank for purposes of Section 881(c) of the Code, is not a 10 percent shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of Borrower and is not a controlled foreign corporation related to Borrower (within the meaning of Section 864(d)(4) of the Code). Thereafter and from time to time, each Lender and L/C Issuer shall submit to Borrower and Administrative Agent such additional duly completed and signed copies of one or the other of such Forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) and such other certificates as may be (i) requested by Borrower in a written notice, directly or through Administrative Agent, to such Lender or L/C Issuer and (ii) required under then current United States law or regulations to avoid or reduce United States withholding taxes on payments in respect of all amounts to be received by such Lender or L/C Issuer, including fees, pursuant to the Loan Documents or the Obligations. Upon the request of Borrower or Administrative Agent, each Lender and L/C Issuer that is a United States person (as such term is defined in Section 7701(a)(30) of the Code) shall submit to Borrower and Administrative Agent a certificate to the effect that it is such a United States person. (c) Inability of Lender to Submit Forms. If any Lender or L/C Issuer determines, as a result of any change in applicable Law, regulation or treaty, or in any official application or interpretation thereof, that it is unable to submit to Borrower or Administrative Agent any form or certificate that such Lender or L/C Issuer is obligated to submit pursuant to subsection (b) of this Section 3.1 or that such Lender or L/C Issuer is required to withdraw or cancel any such form or certificate previously submitted or any such form or certificate otherwise becomes ineffective or inaccurate, such Lender or L/C Issuer shall promptly notify Borrower and Administrative Agent of such fact and the Lender or L/C Issuer shall to that extent not be obligated to provide any such form or certificate and will be entitled to withdraw or cancel any affected form or certificate, as applicable. Section 3.2 Documentary Taxes. Borrower agrees to pay on demand any documentary, stamp or similar taxes payable in respect of this Agreement or any other Loan Document, including

-56- 751970602 interest and penalties, in the event any such taxes are assessed, irrespective of when such assessment is made and whether or not any credit is then in use or available hereunder. Section 3.3 Funding Indemnity. If any Lender shall incur any loss, cost or expense (including any loss, cost or expense incurred by reason of the liquidation or re-employment of deposits or other funds acquired by such Lender to fund or maintain any SOFR Loan or Swing Loan or the relending or reinvesting of such deposits or amounts paid or prepaid to such Lender) as a result of: (a) any payment, prepayment or conversion of a SOFR Loan or Swing Loan on a date other than the last day of its Interest Period, (b) any failure (because of a failure to meet the conditions of Section 4 or otherwise) by Borrower to borrow or continue a SOFR Loan or Swing Loan, or to convert a Base Rate Loan into a SOFR Loan or Swing Loan on the date specified in a notice given pursuant to Section 2.6(a) or 2.7, (c) any failure by Borrower to make any payment of principal on any SOFR Loan or Swing Loan when due (whether by acceleration or otherwise), or (d) any acceleration of the maturity of a SOFR Loan or Swing Loan as a result of the occurrence of any Event of Default hereunder, then, Borrower shall pay to such Lender such amount as will reimburse such Lender for such loss, cost or expense within ten (10) days after receipt of the certificate described in the next sentence. If any Lender makes such a claim for compensation, it shall provide to Borrower, with a copy to Administrative Agent, a certificate setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss, cost or expense) and the amounts shown on such certificate shall be conclusive and binding on Borrower absent manifest error. Section 3.4 Change in Law. Notwithstanding any other provisions of this Agreement or any other Loan Document, if at any time any Change in Law or regulation or in the interpretation thereof makes it unlawful for any Lender to make or continue to maintain any SOFR Loans or to perform its obligations as contemplated hereby, such Lender shall promptly give notice thereof to Borrower and such Lender’s obligations to make or maintain SOFR Loans under this Agreement shall be suspended until it is no longer unlawful for such Lender to make or maintain SOFR Loans. Borrower shall prepay on demand the outstanding principal amount of any such affected SOFR Loans, together with all interest accrued thereon and all other amounts then due and payable to such Lender under this Agreement; provided, that, subject to all of the terms and conditions of this Agreement, Borrower may then elect to borrow the principal amount of the affected SOFR Loans from such Lender by means of Base Rate Loans from such Lender, which Base Rate Loans shall not be made ratably by the Lenders but only from such affected Lender and which shall be determined without reference to clause (c) of the definition of “Base Rate”. Upon any such repayment, the Borrower shall also pay any additional amounts required pursuant to Section 3.3. Section 3.5 Inability to Determine Rates. Subject to Section 3.9, if, on or prior to the first day of any Interest Period for any SOFR Loan:

-57- 751970602 (a) the Administrative Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR” cannot be determined pursuant to the definition thereof, or (b) the Required Lenders determine that for any reason in connection with any request for a SOFR Loan or a conversion thereto or a continuation thereof that Term SOFR for any requested Interest Period with respect to a proposed SOFR Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, and the Required Lenders have provided notice of such determination to the Administrative Agent, then the Administrative Agent will promptly so notify the Borrower and each Lender. Upon notice thereof by the Administrative Agent to the Borrower, any obligation of the Lenders to make or continue SOFR Loans shall be suspended (to the extent of the affected SOFR Loans and, in the case of a SOFR Loan, the affected Interest Periods) until the Administrative Agent revokes such notice. Upon receipt of such notice, (i) the Borrower may revoke any pending request for a borrowing of, conversion to or continuation of SOFR Loans (to the extent of the affected SOFR Loans and, in the case of a SOFR Loan, the affected Interest Periods) or, failing that, the Borrower will be deemed to have converted any such request into a request for a Borrowing of or conversion to Base Rate Loans in the amount specified therein and (ii) any outstanding affected SOFR Loans will be deemed to have been converted into Base Rate Loans immediately or, in the case of a SOFR Loans, at the end of the applicable Interest Period. Upon any such conversion, the Borrower shall also pay any additional amounts required pursuant to Section 3.3. Section 3.6 Increased Cost and Reduced Return. If any Change in Law: (i) shall subject any Lender (or its Lending Office) or the L/C Issuer to any tax, duty or other charge with respect to its SOFR Loans, its Notes, its Letter(s) of Credit, or its participation in any thereof, any Reimbursement Obligations owed to it or its obligation to make SOFR Loans, issue a Letter of Credit, or to participate therein, or shall change the basis of taxation of payments to any Lender (or its Lending Office) or the L/C Issuer of the principal of or interest on its SOFR Loans, Letter(s) of Credit, or participations therein or any other amounts due under this Agreement or any other Loan Document in respect of its SOFR Loans, Letter(s) of Credit, any participation therein, any Reimbursement Obligations owed to it, or its obligation to make SOFR Loans, or issue a Letter of Credit, or acquire participations therein (except for changes in the rate of tax on the overall net income of such Lender or its Lending Office or the L/C Issuer imposed by the jurisdiction in which such Lender’s or the L/C Issuer’s principal executive office or Lending Office is located); or (ii) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including any such requirement imposed by the FRB) against assets of, deposits with or for the account of, or credit extended by, any Lender (or its Lending Office) or the L/C Issuer or shall impose on any Lender (or its Lending Office) or the L/C Issuer or on the interbank market any other condition affecting its SOFR Loans, its Notes, its Letter(s) of Credit, or its participation in any thereof, any Reimbursement Obligation owed to it, or its obligation to make SOFR Loans, or to issue a Letter of Credit, or to participate therein;

-58- 751970602 and the result of any of the foregoing is to increase the cost to such Lender (or its Lending Office) or the L/C Issuer of making or maintaining any SOFR Loan, issuing or maintaining a Letter of Credit, or participating therein, or to reduce the amount of any sum received or receivable by such Lender (or its Lending Office) or the L/C Issuer under this Agreement or under any other Loan Document with respect thereto, by an amount deemed by such Lender or L/C Issuer to be material, then, within 15 days after demand by such Lender or L/C Issuer (with a copy to Administrative Agent), Borrower shall be obligated to pay to such Lender or L/C Issuer such additional amount or amounts as will compensate such Lender or L/C Issuer for such increased cost or reduction. (b) If, after the date hereof, any Lender, the L/C Issuer, or Administrative Agent shall have determined that any Change in Law has had the effect of reducing the rate of return on such Lender’s or L/C Issuer ‘s or such corporation’s capital as a consequence of its obligations hereunder to a level below that which such Lender or L/C Issuer or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or L/C Issuer ‘s or such corporation’s policies with respect to liquidity and capital adequacy) by an amount deemed by such Lender or L/C Issuer to be material, then from time to time, within 15 days after demand by such Lender or L/C Issuer (with a copy to Administrative Agent), Borrower shall pay to such Lender or L/C Issuer, as applicable, such additional amount or amounts as will compensate such Lender or L/C Issuer for such reduction. (c) A certificate of a Lender or L/C Issuer claiming compensation under this Section 3.6 and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive absent manifest error. In determining such amount, such Lender or L/C Issuer may use any reasonable averaging and attribution methods. (d) Failure or delay on the part of any Lender, L/C Issuer or the Administrative Agent to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s, L/C Issuer’s or Administrative Agent’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender, L/C Issuer or Administrative Agent pursuant to this Section for any increased costs incurred or reductions suffered more than 180 days prior to the date that such Lender, L/C Issuer or Administrative Agent, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions, and of such Lender’s, L/C Issuer’s or Administrative Agent’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof). Section 3.7 Lending Offices. Each Lender may, at its option, elect to make its Loans hereunder at the branch, office or affiliate specified on the appropriate signature page hereof (each a “Lending Office”) for each type of Loan available hereunder or at such other of its branches, offices or affiliates as it may from time to time elect and designate in a written notice to Borrower and Administrative Agent. To the extent reasonably possible, a Lender shall designate an alternative branch or funding office with respect to its SOFR Loans to reduce any liability of Borrower to such Lender under Section 3.6 or to avoid the unavailability of SOFR Loans under Section 3.5, so long as such designation is not otherwise disadvantageous to the Lender. Section 3.8 Reserved.

Notwithstanding anything to the contrary herein or in any other Loan Document, if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior any setting of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (a) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document and (y) if a Benchmark Replacement is determined in accordance with clause (b) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is provided to the Lenders without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Administrative Agent has not received, by such time, written notice of objection to such Benchmark Replacement from Lenders comprising the Required Lenders. If the Benchmark Replacement is Daily Simple SOFR, all interest payments will be payable on a monthly basis. (b) Benchmark Replacement Conforming Changes. In connection with the use, administration, adoption or implementation of a Benchmark Replacement, the Administrative Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document. (c) Notice; Standards for Decisions and Determinations. The Administrative Agent will promptly notify the Borrower and the Lenders of (i) the implementation of any Benchmark Replacement and (ii) the effectiveness of any Conforming Changes in connection with the use, administration, adoption or implementation of a Benchmark Replacement. The Administrative Agent will promptly notify the Borrower of the removal or reinstatement of any tenor of a Benchmark pursuant to this Section 3.9. Any determination, decision or election that may be made by the Administrative Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 3.9, 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 or any selection, 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 to this Agreement or any other Loan Document, except, in each case, as expressly required pursuant to this Section 3.9. (d) Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Loan Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i) if the then-current Benchmark is a term rate (including the Term SOFR Reference Rate) and either (A) any tenor for such Benchmark is not

-60- 751970602 displayed on a screen or other information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion or (B) the administration of such Benchmark or the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is not or will not be representative, then the Administrative Agent may modify the definition of “Interest Period” (or any similar or analogous definition) for any Benchmark settings at or after such time to remove such unavailable, non-representative, non-compliant or non-aligned tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not or will not be representative for a Benchmark (including a Benchmark Replacement), then the Administrative Agent may modify the definition of “Interest Period” (or any similar or analogous definition) for all Benchmark settings at or after such time to reinstate such previously removed tenor. Benchmark Unavailability Period. Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower may revoke any pending request for a SOFR Borrowing of, conversion to or continuation of SOFR Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any such request into a request for a Borrowing of or conversion to Base Rate Loans. During a Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of Base Rate based upon the then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of Base Rate.

-87- 751970602 accepted liability therefor in writing), and which remains undischarged, unvacated, unbonded or unstayed for a period of 30 days; (h) an ERISA Event shall occur, that, when taken together with all other ERISA Events that have occurred, could reasonably be expected to result in liability of the Borrower, its Subsidiaries or its ERISA Affiliates in an aggregate amount in excess of $15,000,000; (i) any Change of Control shall occur; (j) Borrower or any Subsidiary shall (i) have entered involuntarily against it an order for relief under the United States Bankruptcy Code, as amended, (ii) not pay, or admit in writing its inability to pay, its debts generally as they become due, (iii) make an assignment for the benefit of creditors, (iv) apply for, seek, consent to or acquiesce in, the appointment of a receiver, custodian, trustee, examiner, liquidator or similar official for it or any substantial part of its Property, (v) institute any proceeding seeking to have entered against it an order for relief under the United States Bankruptcy Code, as amended, to adjudicate it insolvent, or seeking dissolution (except as expressly permitted hereunder), winding up, liquidation, reorganization, arrangement, adjustment or composition of it or its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors or fail to file an answer or other pleading denying the material allegations of any such proceeding filed against it, (vi) take any corporate, limited liability, or other applicable organizational action in furtherance of any matter described in parts (i) through (v) above, or (vii) fail to contest in good faith any appointment or proceeding described in Section 8.1(k); (k) a custodian, receiver, trustee, examiner, liquidator or similar official shall be appointed for Borrower or any Subsidiary, or any substantial part of any of its Property, or a proceeding described in Section 8.1(j)(v) shall be instituted against Borrower or any Subsidiary, and such appointment continues undischarged or such proceeding continues undismissed or unstayed for a period of 60 days; or (l) any Loan Party or any Subsidiary defaults in the payment when due of any amount due under any Bonding Agreement or breaches or defaults with respect to any other term of any Bonding Agreement, (x) if the effect of such failure to pay, default or breach is to cause the related surety to take possession of the work under any of the bonded contracts of such Borrower or any of its Subsidiaries and value of the contract or project that has been taken over by the related surety exceeds $15,000,000 or (y) if the effect of such failure to pay, default or breach is to result in a “Trigger Date”, “Trigger Event” or similar term under any Intercreditor Agreement. Section 8.2 Non Bankruptcy Defaults. When any Event of Default (other than those described in Section 8.1(j) or (k) with respect to Borrower) has occurred and is continuing, Administrative Agent shall, by written notice to Borrower: (a) if so directed by the Required Lenders, terminate the remaining Commitments and all other obligations of the Lenders hereunder on the date stated in such notice (which may be the date thereof); (b) if so directed by the Required Lenders, declare the principal of and the accrued interest on all outstanding Loans to be forthwith due and payable and thereupon all outstanding Loans, including both principal and interest thereon, shall be and become immediately due and payable together with all other amounts payable under the Loan Documents without further demand, presentment, protest or notice of any kind; and (c)

-88- 751970602 if so directed by the Required Lenders, demand that Borrower immediately Cash Collateralize the L/C Obligations, and Borrower agrees to immediately make such payment and acknowledges and agrees that the Lenders would not have an adequate remedy at law for failure by Borrower to honor any such demand and that Administrative Agent, for the benefit of the Lenders, shall have the right to require Borrower to specifically perform such undertaking whether or not any drawings or other demands for payment have been made under any Letter of Credit. Administrative Agent, after giving notice to Borrower pursuant to Section 8.1(c) or this Section 8.2, shall also promptly send a copy of such notice to the other Lenders, but the failure to do so shall not impair or annul the effect of such notice. Section 8.3 Bankruptcy Defaults. When any Event of Default described in Section 8.1(j) or (k) with respect to Borrower has occurred and is continuing, then all outstanding Loans shall immediately become due and payable together with all other amounts payable under the Loan Documents without presentment, demand, protest or notice of any kind, the obligation of the Lenders to extend further credit pursuant to any of the terms hereof shall immediately terminate and Borrower shall immediately Cash Collateralize the L/C Obligations, Borrower acknowledging and agreeing that the Lenders would not have an adequate remedy at law for failure by Borrower to honor any such demand and that the Lenders, and Administrative Agent on their behalf, shall have the right to require Borrower to specifically perform such undertaking whether or not any draws or other demands for payment have been made under any of the Letters of Credit. Section 8.4 Collateral for Undrawn Letters of Credit. If the prepayment of the amount available for drawing under any or all outstanding Letters of Credit is required under Section 2.9(b), Section 2.17, Section 8.2 or Section 8.3 above, Borrower shall forthwith pay the amount required to be so prepaid, to be held by Administrative Agent as provided in subsection (b) below. (b) All amounts prepaid pursuant to subsection (a) above shall be held by Administrative Agent in one or more separate collateral accounts (each such account, and the credit balances, properties, and any investments from time to time held therein, and any substitutions for such account, any certificate of deposit or other instrument evidencing any of the foregoing and all proceeds of and earnings on any of the foregoing being collectively called the “Collateral Account”) as security for, and for application by Administrative Agent (to the extent available) to, the reimbursement of any payment under any Letter of Credit then or thereafter made by the L/C Issuer, and to the payment of the unpaid balance of all other Obligations (and to all Hedging Liability and Funds Transfer and Deposit Account Liability). The Collateral Account shall be held in the name of and subject to the exclusive dominion and control of Administrative Agent for the benefit of Administrative Agent, the Lenders, and the L/C Issuer. If and when requested by Borrower, Administrative Agent shall invest funds held in the Collateral Account from time to time in direct obligations of, or obligations the principal of and interest on which are unconditionally guaranteed by, the United States of America with a remaining maturity of one year or less, provided that Administrative Agent is irrevocably authorized to sell investments held in the Collateral Account when and as required to make payments out of the Collateral Account for application to amounts due and owing from Borrower to the L/C Issuer, Administrative Agent or the Lenders; provided, that (i) if Borrower shall have made payment of all obligations referred to in subsection (a) above required under Section 2.9(b) and Section 2.17, if any, at the request of Borrower Administrative Agent shall release to Borrower amounts held in the Collateral Account so long as at the time of the release and after giving effect thereto no Default or Event of Default

-89- 751970602 exists and, in the case of Section 2.17, the Defaulting Lender Period with respect to the relevant Defaulting Lender has terminated, and (ii) if Borrower shall have made payment of all obligations referred to in subsection (a) above required under Section 8.2 or 8.3, so long as no Letters of Credit, Commitments, Loans or other Obligations, Hedging Liability, or Funds Transfer and Deposit Account Liability remain outstanding, at the request of Borrower Administrative Agent shall release to Borrower any remaining amounts held in the Collateral Account. Section 8.5 Notice of Default. Administrative Agent shall give notice to Borrower under Section 8.1(c) promptly upon being requested to do so by any Lender and shall thereupon notify all the Lenders thereof. SECTION 9. ADMINISTRATIVE AGENT. Section 9.1 Appointment and Authorization of Administrative Agent. Each Lender and the L/C Issuer hereby appoints BMO Harris Bank N.A. as Administrative Agent under the Loan Documents and hereby authorizes Administrative Agent to take such action as Administrative Agent on its behalf and to exercise such powers under the Loan Documents as are delegated to Administrative Agent by the terms thereof, together with such powers as are reasonably incidental thereto. The Lenders and L/C Issuer expressly agree that Administrative Agent is not acting as a fiduciary of the Lenders or the L/C Issuer in respect of the Loan Documents, Borrower or otherwise, and nothing herein or in any of the other Loan Documents shall result in any duties or obligations on Administrative Agent or any of the Lenders or L/C Issuer except as expressly set forth herein. Section 9.2 Administrative Agent and its Affiliates. Administrative Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any other Lender and may exercise or refrain from exercising such rights and power as though it were not Administrative Agent, and Administrative Agent and its affiliates may accept deposits from, lend money to, and generally engage in any kind of business with Borrower or any Affiliate of Borrower as if it were not Administrative Agent under the Loan Documents. The term “Lender” as used herein and in all other Loan Documents, unless the context otherwise clearly requires, includes Administrative Agent in its individual capacity as a Lender (if applicable). Section 9.3 Action by Administrative Agent. If Administrative Agent receives from Borrower a written notice of an Event of Default pursuant to Section 8.5, Administrative Agent shall promptly give each of the Lenders and L/C Issuer written notice thereof. The obligations of Administrative Agent under the Loan Documents are only those expressly set forth therein. Without limiting the generality of the foregoing, Administrative Agent shall not be required to take any action hereunder with respect to any Default or Event of Default, except as expressly provided in Sections 8.2 and 8.5. Upon the occurrence of an Event of Default, Administrative Agent shall take such action to enforce its Lien on the Collateral and to preserve and protect the Collateral as may be directed by the Required Lenders. Unless and until the Required Lenders give such direction, Administrative Agent may (but shall not be obligated to) take or refrain from taking such actions as it deems appropriate and in the best interest of all the Lenders and L/C Issuer. In no event, however, shall Administrative Agent be required to take any action in violation of applicable law or of any provision of any Loan Document, and Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder or under any other Loan Document

-90- 751970602 unless it first receives any further assurances of its indemnification from the Lenders that it may require, including prepayment of any related expenses and any other protection it requires against any and all costs, expense, and liability which may be incurred by it by reason of taking or continuing to take any such action. Administrative Agent shall be entitled to assume that no Default or Event of Default exists unless notified in writing to the contrary by a Lender, the L/C Issuer, or Borrower. In all cases in which the Loan Documents do not require Administrative Agent to take specific action, Administrative Agent shall be fully justified in using its discretion in failing to take or in taking any action thereunder. Any instructions of the Required Lenders, or of any other group of Lenders called for under the specific provisions of the Loan Documents, shall be binding upon all the Lenders and the holders of the Obligations. Section 9.4 Consultation with Experts. Administrative Agent may consult with legal counsel, independent public accountants, and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts. Section 9.5 Liability of Administrative Agent; Credit Decision. Neither Administrative Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or not taken by it in connection with the Loan Documents: (i) with the consent or at the request of the Required Lenders or (ii) in the absence of its own gross negligence, bad faith or willful misconduct. Neither Administrative Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into or verify: (i) any statement, warranty or representation made in connection with this Agreement, any other Loan Document or any Credit Event; (ii) the performance or observance of any of the covenants or agreements of any Loan Party contained herein or in any other Loan Document; (iii) the satisfaction of any condition specified in Section 4, except receipt of items required to be delivered to Administrative Agent; or (iv) the validity, effectiveness, genuineness, enforceability, perfection, value, worth or collectability hereof or of any other Loan Document or of any other documents or writing furnished in connection with any Loan Document or of any Collateral; and Administrative Agent makes no representation of any kind or character with respect to any such matter mentioned in this sentence. Administrative Agent may execute any of its duties under any of the Loan Documents by or through employees, agents, and attorneys in fact and shall not be answerable to the Lenders, the L/C Issuer, Borrower, or any other Person for the default or misconduct of any such agents or attorneys in fact selected with reasonable care. Administrative Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, other document or statement (whether written or oral) believed by it to be genuine or to be sent by the proper party or parties. In particular and without limiting any of the foregoing, Administrative Agent shall have no responsibility for confirming the accuracy of any compliance certificate or other document or instrument received by it under the Loan Documents. Administrative Agent may treat the payee of any Obligation as the holder thereof until written notice of transfer shall have been filed with Administrative Agent signed by such payee in form satisfactory to Administrative Agent. Each Lender and L/C Issuer acknowledges that it has independently and without reliance on Administrative Agent or any other Lender or L/C Issuer, and based upon such information, investigations and inquiries as it deems appropriate, made its own credit analysis and decision to extend credit to Borrower in the manner set forth in the Loan Documents. It shall be the responsibility of each Lender and L/C Issuer to keep itself informed as to the creditworthiness of Borrower and its Subsidiaries, and Administrative Agent shall have no liability to any Lender or L/C Issuer with respect thereto.

-91- 751970602 Section 9.6 Indemnity. The Lenders shall ratably, in accordance with their respective Percentages, indemnify and hold Administrative Agent, and its directors, officers, employees, agents, and representatives harmless from and against any liabilities, losses, costs or expenses suffered or incurred by it under any Loan Document or in connection with the transactions contemplated thereby, regardless of when asserted or arising, except to the extent they are promptly reimbursed for the same by Borrower and except to the extent that any event giving rise to a claim was caused by the gross negligence, bad faith or willful misconduct of the party seeking to be indemnified. The obligations of the Lenders under this Section shall survive termination of this Agreement. Administrative Agent shall be entitled to offset amounts received for the account of a Lender under this Agreement against unpaid amounts due from such Lender to Administrative Agent, any L/C Issuer, or Swing Line Lender hereunder (whether as fundings of participations, indemnities or otherwise, and with any amounts offset for the benefit of Administrative Agent to be held by it for its own account and with any amounts offset for the benefit of a L/C Issuer or Swing Line Lender to be remitted by Administrative Agent to or for the account of such L/C Issuer or Swing Line Lender, as applicable), but shall not be entitled to offset against amounts owed to Administrative Agent, any L/C Issuer or Swing Line Lender by any Lender arising outside of this Agreement and the other Loan Documents. Section 9.7 Resignation of Administrative Agent and Successor Administrative Agent. Administrative Agent may resign at any time by giving written notice thereof to the Lenders, the L/C Issuer, and Borrower. Upon any such resignation of Administrative Agent, the Required Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which may be any Lender hereunder or any commercial bank, or an Affiliate of a commercial bank, having an office in the United States of America and having a combined capital and surplus of at least $200,000,000. Upon the acceptance of its appointment as Administrative Agent hereunder, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Administrative Agent under the Loan Documents, and the retiring Administrative Agent shall be discharged from its duties and obligations thereunder. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Section 9 and all protective provisions of the other Loan Documents shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent, but no successor Administrative Agent shall in any event be liable or responsible for any actions of its predecessor. If Administrative Agent resigns and no successor is appointed, the rights and obligations of such Administrative Agent shall be automatically assumed by the Required Lenders and (i) Borrower shall be directed to make all payments due each Lender and L/C Issuer hereunder directly to such Lender or L/C Issuer and (ii) Administrative Agent’s rights in the Collateral Documents shall be assigned without representation, recourse or warranty to the Lenders and L/C Issuer as their interests may appear. Section 9.8 L/C Issuer and Swing Line Lender. The L/C Issuer shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith, and the Swing Line Lender shall act on behalf of the Lenders with respect to the Swing Loans made hereunder. The L/C Issuer and the Swing Line Lender shall each have all of the benefits and immunities (i) provided to Administrative Agent in this Section 9 with respect to any

-92- 751970602 acts taken or omissions suffered by the L/C Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and the Applications pertaining to such Letters of Credit or by the Swing Line Lender in connection with Swing Loans made or to be made hereunder as fully as if the term “Administrative Agent”, as used in this Section 9, included the L/C Issuer and the Swing Line Lender with respect to such acts or omissions and (ii) as additionally provided in this Agreement with respect to such L/C Issuer or Swing Line Lender, as applicable. Section 9.9 Hedging Liability and Funds Transfer and Deposit Account Liability Arrangements. By virtue of a Lender’s execution of this Agreement or an assignment agreement pursuant to Section 11.10, as the case may be, any Affiliate of such Lender (and any Person that was a Lender or an Affiliate of a Lender at the time of the entering into such agreement or arrangement) with whom Borrower or any Guarantor has entered into an agreement creating Hedging Liability or Funds Transfer and Deposit Account Liability shall be deemed a Lender party hereto for purposes of any reference in a Loan Document to the parties for whom Administrative Agent is acting, it being understood and agreed that the rights and benefits of such Affiliate (or such Person that was a Lender or an Affiliate of a Lender at the time of the entering into such agreement or arrangement) under the Loan Documents consist exclusively of such Affiliate’s (or such Person’s) right to share in payments and collections out of the Collateral and the Guaranties as more fully set forth in Section 2.13. Each such Affiliate of a Lender shall, for the avoidance of doubt, be deemed to have agreed to the provisions of Section 9.13. In connection with any such distribution of payments and collections, or any request for the release of the Guaranties and Administrative Agent’s Liens in connection with the termination of the Commitments and the payment in full of the Obligations, Administrative Agent shall be entitled to assume no amounts are due to any Lender or its Affiliate (or any Person that was a Lender or an Affiliate of a Lender at the time of the entering into such agreement or arrangement) with respect to Hedging Liability or Funds Transfer and Deposit Account Liability unless such Lender has notified Administrative Agent in writing of the amount of any such liability owed to it or its Affiliate (or such other Person) prior to such distribution or payment or release of Guaranties and Liens. Section 9.10 Designation of Additional Agents. Administrative Agent shall have the continuing right, for purposes hereof, at any time and from time to time to designate one or more of the Lenders (and/or its or their Affiliates) as “syndication agents,” “documentation agents,” “book runners,” “lead arrangers,” “arrangers,” or other designations for purposes hereto, but such designation shall have no substantive effect, and such Lenders and their Affiliates shall have no additional powers, duties or responsibilities as a result thereof. Section 9.11 Authorization to Release or Subordinate or Limit Liens. Administrative Agent is hereby irrevocably authorized by each of the Lenders and the L/C Issuer to (a) release any Lien covering any Collateral that is sold, transferred, or otherwise disposed of in accordance with the terms and conditions of this Agreement and the relevant Collateral Documents (including a sale, transfer, or disposition permitted by the terms of Section 7.4 or which has otherwise been consented to in accordance with Section 11.11), (b) release or subordinate any Lien on Collateral consisting of goods financed with purchase money indebtedness or under a Capital Lease to the extent such purchase money indebtedness or Capitalized Lease Obligation, and the Lien securing the same, are permitted by Sections 7.1(b) and 7.2(d), (c) reduce or limit the amount of the indebtedness secured by any particular item of Collateral to an amount not less than the estimated value thereof to the extent necessary to reduce mortgage registry, filing and similar tax, (d) release

-93- 751970602 Liens on the Collateral following termination or expiration of the Commitments and payment in full in cash of the Obligations and, if then due, Hedging Liability and Funds Transfer and Deposit Account Liability and (e) subordinate any Lien on Collateral contemplated by clause (i) of the proviso to Section 7.2(l) to the extent required under the applicable Bonding Agreement or by the counterparty thereto in accordance with the terms of such Bonding Agreement. Section 9.12 Authorization to Enter into, and Enforcement of, the Collateral Documents. Administrative Agent is hereby irrevocably authorized by each of the Lenders and the L/C Issuer to execute and deliver the Collateral Documents (including any Intercreditor Agreement contemplated hereunder) on behalf of each of the Lenders and their Affiliates and the L/C Issuer and to take such action and exercise such powers under the Collateral Documents as Administrative Agent considers appropriate, provided Administrative Agent shall not amend the Collateral Documents unless such amendment is agreed to in writing by the Required Lenders. Each Lender and L/C Issuer acknowledges and agrees that it will be bound by the terms and conditions of the Collateral Documents upon the execution and delivery thereof by Administrative Agent. Except as otherwise specifically provided for herein, no Lender (or its Affiliates) or L/C Issuer, other than Administrative Agent, shall have the right to institute any suit, action or proceeding in equity or at law for the foreclosure or other realization upon any Collateral or for the execution of any trust or power in respect of the Collateral or for the appointment of a receiver or for the enforcement of any other remedy under the Collateral Documents; it being understood and intended that no one or more of the Lenders (or their Affiliates) or L/C Issuer shall have any right in any manner whatsoever to affect, disturb or prejudice the Lien of Administrative Agent (or any security trustee therefor) under the Collateral Documents by its or their action or to enforce any right thereunder, and that all proceedings at law or in equity shall be instituted, had, and maintained by Administrative Agent (or its security trustee) in the manner provided for in the relevant Collateral Documents for the benefit of the Lenders, the L/C Issuer, and their Affiliates. Section 9.13 Recovery of Erroneous Payments. Notwithstanding anything to the contrary in this Agreement, if at any time Administrative Agent determines (in its sole and absolute discretion) that it has made a payment hereunder in error to any Lender, L/C Issuer or other Secured Party, whether or not in respect of an Obligation due and owing by Borrower at such time, where such payment is a Rescindable Amount, then in any such event, each such Person receiving a Rescindable Amount severally agrees to repay to Administrative Agent forthwith on demand the Rescindable Amount received by such Person in immediately available funds in the currency so received, with interest thereon, for each day from and including the date such Rescindable Amount is received by it to but excluding the date of payment to Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by Administrative Agent in accordance with banking industry rules on interbank compensation. Each Lender, each L/C Issuer and each other Secured Party irrevocably waives any and all defenses, including any “discharge for value” (under which a creditor might otherwise claim a right to retain funds mistakenly paid by a third party in respect of a debt owed by another), “good consideration”, “change of position” or similar defenses (whether at law or in equity) to its obligation to return any Rescindable Amount. Administrative Agent shall inform each Lender, L/C Issuer or other Secured Party that received a Rescindable Amount promptly upon determining that any payment made to such Person comprised, in whole or in part, a Rescindable Amount. Each Person’s obligations, agreements and waivers under this Section 9.13 shall survive the resignation or replacement of the Administrative Agent, any transfer of rights or obligations by, or the replacement of, a Lender or L/C Issuer, the termination of the

-94- 751970602 Commitments and/or the repayment, satisfaction or discharge of all Obligations (or any portion thereof) under any Loan Document. SECTION 10. THE GUARANTEES. Section 10.1 The Guarantees. To induce the Lenders and L/C Issuer to provide the credits described herein and in consideration of benefits expected to accrue to Borrower by reason of the Commitments and for other good and valuable consideration, receipt of which is hereby acknowledged, each Subsidiary party hereto (including any Subsidiary executing an Additional Guarantor Supplement in the form attached hereto as Exhibit G or such other form acceptable to Administrative Agent) hereby unconditionally and irrevocably guarantees jointly and severally to Administrative Agent, the Lenders, and the L/C Issuer and their Affiliates (and any Person that was a Lender or an Affiliate of a Lender at the time of the entering into such agreement or arrangement), the due and punctual payment of all present and future Obligations, Hedging Liability, and Funds Transfer and Deposit Account Liability, including, but not limited to, the due and punctual payment of principal of and interest on the Loans, the Reimbursement Obligations, and the due and punctual payment of all other Obligations now or hereafter owed by Borrower under the Loan Documents and the due and punctual payment of all Hedging Liability and Funds Transfer and Deposit Account Liability, in each case as and when the same shall become due and payable, whether at stated maturity, by acceleration, or otherwise, according to the terms hereof and thereof (including all interest, costs, fees, and charges after the entry of an order for relief against Borrower or such other obligor in a case under the United States Bankruptcy Code or any similar proceeding, whether or not such interest, costs, fees and charges would be an allowed claim against Borrower or any such obligor in any such proceeding). In case of failure by Borrower or other obligor punctually to pay any Obligations, Hedging Liability, or Funds Transfer and Deposit Account Liability guaranteed hereby, each Guarantor hereby unconditionally agrees to make such payment or to cause such payment to be made punctually as and when the same shall become due and payable, whether at stated maturity, by acceleration, or otherwise, and as if such payment were made by Borrower or such obligor. (b) Each Qualified ECP Guarantor hereby jointly and severally absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Loan Party to honor all of its obligations under this Guaranty in respect of Swap Obligations. The obligations of each Qualified ECP Guarantor under this Section 10.1(b) shall remain in full force and effect until payment in full of the Hedging Liability, and Funds Transfer and Deposit Account Liability. Each Qualified ECP Guarantor intends that this Section 10.1(b) constitute, and this Section 10.1(b) shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Loan Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act. Section 10.2 Guarantee Unconditional. The obligations of each Guarantor under this Section 10 shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged, or otherwise affected by: (a) any extension, renewal, settlement, compromise, waiver, or release in respect of any obligation of Borrower or other obligor or of any other guarantor under this Agreement or any other Loan Document or by operation of law or otherwise;

-95- 751970602 (b) any modification or amendment of or supplement to this Agreement or any other Loan Document or any agreement relating to Hedging Liability or Funds Transfer and Deposit Account Liability; (c) any change in the corporate existence, structure, or ownership of, or any insolvency, bankruptcy, reorganization, or other similar proceeding affecting, Borrower or other obligor, any other guarantor, or any of their respective assets, or any resulting release or discharge of any obligation of Borrower or other obligor or of any other guarantor contained in any Loan Document; (d) the existence of any claim, set off, or other rights which Borrower or other obligor or any other guarantor may have at any time against Administrative Agent, any Lender, the L/C Issuer or any other Person, whether or not arising in connection herewith; (e) any failure to assert, or any assertion of, any claim or demand or any exercise of, or failure to exercise, any rights or remedies against Borrower or other obligor, any other guarantor, or any other Person or Property; (f) any application of any sums by whomsoever paid or howsoever realized to any obligation of Borrower or other obligor, regardless of what obligations of Borrower or other obligor remain unpaid; (g) any invalidity or unenforceability relating to or against Borrower or other obligor or any other guarantor for any reason of this Agreement or of any other Loan Document or any agreement relating to Hedging Liability or Funds Transfer and Deposit Account Liability or any provision of applicable law or regulation purporting to prohibit the payment by Borrower or other obligor or any other guarantor of the principal of or interest on any Loan or any Reimbursement Obligation or any other amount payable under the Loan Documents or any agreement relating to Hedging Liability or Funds Transfer and Deposit Account Liability; or (h) any other act or omission to act or delay of any kind by Administrative Agent, any Lender, the L/C Issuer, or any other Person or any other circumstance whatsoever that might, but for the provisions of this paragraph, constitute a legal or equitable discharge of the obligations of any Guarantor under this Section 10. Section 10.3 Discharge Only upon Payment in Full; Reinstatement in Certain Circumstances. Each Guarantor’s obligations under this Section 10 shall remain in full force and effect until the Commitments are terminated, all Letters of Credit have expired, and the principal of and interest on the Loans and all other amounts payable by Borrower and the Guarantors under this Agreement and all other Loan Documents and, if then outstanding and unpaid, all Hedging Liability and Funds Transfer and Deposit Account Liability shall have been paid in full in cash. If at any time any payment of the principal of or interest on any Loan or any Reimbursement Obligation or any other amount payable by Borrower or other obligor or any Guarantor under the Loan Documents or any agreement relating to Hedging Liability or Funds Transfer and Deposit Account Liability is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy, or reorganization of Borrower or other obligor or of any guarantor, or otherwise, each Guarantor’s obligations under this Section 10 with respect to such payment shall be reinstated at such time as though such payment had become due but had not been made at such time.

-96- 751970602 Section 10.4 Subrogation. Each Guarantor agrees it will not exercise any rights which it may acquire by way of subrogation by any payment made hereunder, or otherwise, until all the Obligations, Hedging Liability, and Funds Transfer and Deposit Account Liability shall have been paid in full subsequent to the termination of all the Commitments and expiration of all Letters of Credit. If any amount shall be paid to a Guarantor on account of such subrogation rights at any time prior to the later of (x) the payment in full of the Obligations, Hedging Liability, and Funds Transfer and Deposit Account Liability and all other amounts payable by Borrower hereunder and the other Loan Documents and (y) the termination of the Commitments and expiration of all Letters of Credit, such amount shall be held in trust for the benefit of Administrative Agent, the Lenders, and the L/C Issuer (and their Affiliates) and shall forthwith be paid to Administrative Agent for the benefit of the Lenders and L/C Issuer (and their Affiliates) or be credited and applied upon the Obligations, Hedging Liability, and Funds Transfer and Deposit Account Liability, whether matured or unmatured, in accordance with the terms of this Agreement. Section 10.5 Waivers. Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest, and any notice not provided for herein, as well as any requirement that at any time any action be taken by Administrative Agent, any Lender, the L/C Issuer, or any other Person against Borrower or other obligor, another guarantor, or any other Person. Section 10.6 Limit on Recovery. Notwithstanding any other provision hereof, the right of recovery against each Guarantor under this Section 10 shall not exceed $1.00 less than the lowest amount which would render such Guarantor’s obligations under this Section 10 void or voidable under applicable law, including fraudulent conveyance law. Section 10.7 Stay of Acceleration. If acceleration of the time for payment of any amount payable by Borrower or other obligor under this Agreement or any other Loan Document, or under any agreement relating to Hedging Liability or Funds Transfer and Deposit Account Liability, is stayed upon the insolvency, bankruptcy or reorganization of Borrower or such obligor, all such amounts otherwise subject to acceleration under the terms of this Agreement or the other Loan Documents, or under any agreement relating to Hedging Liability or Funds Transfer and Deposit Account Liability, shall nonetheless be payable by the Guarantors hereunder forthwith on demand by Administrative Agent made at the request of the Required Lenders. Section 10.8 Benefit to Guarantors. Borrower and the Guarantors are engaged in related businesses and integrated to such an extent that the financial strength and flexibility of Borrower has a direct impact on the success of each Guarantor. Each Guarantor will derive substantial direct and indirect benefit from the extensions of credit hereunder. Section 10.9 Guarantor Covenants. Each Guarantor shall take such action as Borrower is required by this Agreement to cause such Guarantor to take, and shall refrain from taking such action as Borrower is required by this Agreement to prohibit such Guarantor from taking. SECTION 11. MISCELLANEOUS. Section 11.1 No Waiver, Cumulative Remedies. No delay or failure on the part of Administrative Agent, the L/C Issuer, or any Lender, or on the part of the holder or holders of any of the Obligations, in the exercise of any power or right under any Loan Document shall operate

-97- 751970602 as a waiver thereof or as an acquiescence in any default, nor shall any single or partial exercise of any power or right preclude any other or further exercise thereof or the exercise of any other power or right. The rights and remedies hereunder of Administrative Agent, the L/C Issuer, the Lenders, and of the holder or holders of any of the Obligations are cumulative to, and not exclusive of, any rights or remedies which any of them would otherwise have. Section 11.2 Non-Business Days. If any payment hereunder becomes due and payable on a day which is not a Business Day, the due date of such payment shall be extended to the next succeeding Business Day on which date such payment shall be due and payable. In the case of any payment of principal falling due on a day which is not a Business Day, interest on such principal amount shall continue to accrue during such extension at the rate per annum then in effect, which accrued amount shall be due and payable on the next scheduled date for the payment of interest. Section 11.3 Survival of Representations. All representations and warranties made herein or in any other Loan Document or in certificates given pursuant hereto or thereto shall survive the execution and delivery of this Agreement and the other Loan Documents, and shall continue in full force and effect with respect to the date as of which they were made as long as any credit is in use or available hereunder. Section 11.4 Survival of Indemnity and Certain Other Provisions. All indemnity provisions and other provisions relative to reimbursement to the Lenders and L/C Issuer of amounts sufficient to protect the yield of the Lenders and L/C Issuer with respect to the Loans and Letters of Credit, including, but not limited to, Sections 3.3, 3.6, and 11.13, shall survive the payment and satisfaction of all Obligations and the termination of this Agreement and the other Loan Documents, and shall remain in force beyond the expiration of any applicable statute of limitations and payment or satisfaction in full of any single claim thereunder. All such indemnity and other provisions shall be binding upon the successors and assigns of Borrower and shall inure to the benefit of each applicable Indemnitee and its successors and assigns. Section 11.5 Sharing of Set Off. Each Lender agrees with each other Lender a party hereto that if such Lender shall receive and retain any payment, whether by set off or application of deposit balances or otherwise, on any of the Loans or Reimbursement Obligations in excess of its ratable share of payments on all such Obligations then outstanding to the Lenders, then such Lender shall purchase for cash at face value, but without recourse, ratably from each of the other Lenders such amount of the Loans or Reimbursement Obligations, or participations therein, held by each such other Lenders (or interest therein) as shall be necessary to cause such Lender to share such excess payment ratably with all the other Lenders; provided, that if any such purchase is made by any Lender, and if such excess payment or part thereof is thereafter recovered from such purchasing Lender, the related purchases from the other Lenders shall be rescinded ratably and the purchase price restored as to the portion of such excess payment so recovered, but without interest. For purposes of this Section, amounts owed to or recovered by the L/C Issuer in connection with Reimbursement Obligations in which Lenders have been required to fund their participation shall be treated as amounts owed to or recovered by the L/C Issuer as a Lender hereunder. Section 11.6 Notices. Except as otherwise specified herein, all notices hereunder and under the other Loan Documents shall be in writing (including, without limitation, notice by

Section 11.9 Participants. Each Lender shall have the right at its own cost to grant participations (to be evidenced by one or more agreements or certificates of participation) in the Loans made and Reimbursement Obligations and/or Commitments held by such Lender at any time and from time to time to one or more other Persons (other than a natural person, the Borrower, any of the Subsidiaries or any Affiliate the Borrower or its Subsidiaries or, to the extent that the list of Disqualified Institutions is made available to all Lenders, any Disqualified Institution); provided that no such participation shall relieve any Lender of any of its obligations under this Agreement, and, provided, further that no such participant shall have any rights under this Agreement except as provided in this Section, and Administrative Agent shall have no obligation or responsibility to such participant. Any agreement pursuant to which such participation is granted shall provide that the granting Lender shall retain the sole right and responsibility to enforce the obligations of Borrower under this Agreement and the other Loan Documents including the right to approve any amendment, modification or waiver of any provision of the Loan Documents, except that such agreement may provide that such Lender will not agree to any modification, amendment or waiver of the Loan Documents that would reduce the amount of or postpone any fixed date for payment of any Obligation in which such participant has an interest. Any party to which such a participation has been granted shall have the benefits of Section 3.4 and Section 3.6. Section 11.10 Assignments. (a) Any Lender may at any time assign to one or more Eligible Assignees all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions: (i) Minimum Amounts. (A) In the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans and participation interest in L/C Obligations at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and (B) in any case not described in subsection (a)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans and participation interest in L/C Obligations outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans and participation interest in L/C Obligations of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to Administrative Agent or, if “Effective Date” is specified in the Assignment and Acceptance, as of the Effective Date) shall not be less than $5,000,000, in the case of any assignment in respect of the Revolving Credit, or $1,000,000, in the case of any assignment in respect of any Term Loan, unless each of Administrative Agent and, so long as no Event of Default has occurred and is continuing, Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed);

-100- 751970602 (ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned, except that this clause (ii) shall not prohibit any Lender from assigning all or a portion of its rights and obligations among separate Credits on a non-pro rata basis. (iii) Required Consents. No consent shall be required for any assignment except to the extent required by Section 11.10(a)(i)(B) and, in addition: (A) the consent of Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to Administrative Agent within five (5) Business Days after having received notice thereof; (B) the consent of Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments in respect of (i) the Revolving Credit if such assignment is to a Person that is not a Lender with a Commitment in respect of such facility, an Affiliate of such Lender or an Approved Fund with respect to such Lender or (ii) the Term Loans to a Person who is not a Lender, an Affiliate of a Lender or an Approved Fund; (C) the consent of the L/C Issuer (such consent not to be unreasonably withheld or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more Letters of Credit (whether or not then outstanding); and (D) the consent of the Swing Line Lender (such consent not to be unreasonably withheld or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more Swing Loans (whether or not then outstanding). (iv) Assignment and Acceptance. The parties to each assignment shall execute and deliver to Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500, and the assignee, if it is not a Lender, shall deliver to Administrative Agent an Administrative Questionnaire. (v) No Assignment to Certain Persons. No such assignment shall be made to (A) Borrower or any of its Affiliates or Subsidiaries, (B) any Defaulting Lender or any of its Affiliates, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B), or (C) subject to clause (d) below, so long as the list of Disqualified Institutions is made available to each Lender, any Disqualified Institution. (vi) No Assignment to Natural Persons. No such assignment shall be made to a natural person.

-101- 751970602 Subject to acceptance and recording thereof by Administrative Agent pursuant to Section 11.10(b), from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 11.4 and 11.13 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 11.9. (vii) Register. Administrative Agent, acting solely for this purpose as an agent of Borrower, shall maintain at one of its offices in Chicago, Illinois, a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and Borrower, Administrative Agent, and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice. Notwithstanding the foregoing, in no event shall the Administrative Agent be obligated to ascertain, monitor or inquire as to whether any Lender is a Disqualified Institution. (b) Any Lender may at any time pledge or grant a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any such pledge or grant to a Federal Reserve Bank, and this Section shall not apply to any such pledge or grant of a security interest; provided that no such pledge or grant of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or secured party for such Lender as a party hereto; provided further, however, the right of any such pledgee or grantee (other than any Federal Reserve Bank) to further transfer all or any portion of the rights pledged or granted to it, whether by means of foreclosure or otherwise, shall be at all times subject to the terms of this Agreement. (c) Notwithstanding anything to the contrary herein, if at any time the Swing Line Lender assigns all of its Revolving Credit Commitments and Revolving Loans pursuant to subsection (a) above, the Swing Line Lender may terminate the Swing Line. In the event of such termination of the Swing Line, Borrower shall be entitled to appoint another Lender to act as the successor Swing Line Lender hereunder (with such Lender’s consent); provided, that the failure of Borrower to appoint a successor shall not affect the resignation of the Swing Line Lender. If the Swing Line Lender terminates the Swing Line, it shall retain all of the rights of the Swing Line Lender provided hereunder with respect to Swing Loans made by it and outstanding as of the effective date of such termination, including the right to require Lenders to make Revolving Loans or fund participations in outstanding Swing Loans pursuant to Section 2.7.

-102- 751970602 (d) Disqualified Institutions. (i) No assignment or participation shall be made to any Person that was a Disqualified Institution as of the date (the “Trade Date”) on which the assigning Lender entered into a binding agreement to sell and assign or grant a participation in all or a portion of its rights and obligations under this Agreement to such Person (unless the Borrower has consented to such assignment or participation in writing in its sole and absolute discretion, in which case such Person will not be considered a Disqualified Institution for the purpose of such assignment or participation). For the avoidance of doubt, with respect to any assignee or Participant that becomes a Disqualified Institution after the applicable Trade Date (including as a result of the delivery of a written supplement to the list of “Disqualified Institutions” referred to in, the definition of “Disqualified Institution”), (x) such assignee or Participant shall not retroactively be disqualified from becoming a Lender or Participant and (y) the execution by a Borrower of an Assignment and Acceptance with respect to such assignee will not by itself result in such assignee no longer being considered a Disqualified Institution. Any assignment or participation in violation of this clause (i) shall not be void, but the other provisions of this clause (i) shall apply. (ii) If any assignment or participation is made to any Disqualified Institution without the Borrower’s prior written consent in violation of clause (i) above, or if any Person becomes a Disqualified Institution after the applicable Trade Date, the Borrower may, at its sole expense and effort, upon notice to the applicable Disqualified Institution and the Administrative Agent, require such Disqualified Institution to assign, without recourse (in accordance with and subject to the restrictions and consent rights contained in this Section 11.9), all of its interest, rights and obligations under this Agreement to one or more Persons at the lesser of (x) the principal amount thereof and (y) the amount that such Disqualified Institution paid to acquire such interests, rights and obligations in each case plus accrued interest, accrued fees and all other amounts (other than principal amounts) payable to it hereunder. (iii) Notwithstanding anything to the contrary contained in this Agreement, Disqualified Institutions to whom an assignment or participation is made in violation of clause (i) above (A) will not have the right to (x) receive information, reports or other materials provided to Lenders by the Loan Parties, the Administrative Agent or any other Lender, (y) attend or participate in meetings attended by the Lenders and the Administrative Agent, or (z) access any electronic site established for the Lenders or confidential communications from counsel to or financial advisors of the Administrative Agent or the Lenders and (B) for purposes of any consent to any amendment, waiver or modification of, or any action under, and for the purpose of any direction to the Administrative Agent or any Lender to undertake any action (or refrain from taking any action) under this Agreement or any other Loan Document, each Disqualified Institution will be deemed to have consented in the same proportion as the Lenders that are not Disqualified Institutions consented to such matter. (iv) The Administrative Agent shall have the right, and the Borrower hereby expressly authorizes the Administrative Agent, to (A) post the list of Disqualified Institutions provided by the Borrower and any updates thereto from time to time

-103- 751970602 (collectively, the “DQ List”) on a Platform, including that portion of such Platform that is designated for “public side” Lenders and/or (B) provide the DQ List to each Lender or potential Lender requesting the same. (v) The Administrative Agent shall not be responsible or have any liability for, or have any duty to ascertain, inquire into, monitor or enforce, compliance with the provisions hereof relating to Disqualified Institutions. Without limiting the generality of the foregoing the Administrative Agent shall not have any liability with respect to or arising out of any assignment or participation of Loans, or disclosure of confidential information, by any other Person to any Disqualified Institution. Section 11.11 Amendments. Any provision of this Agreement or the other Loan Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by (a) Borrower, (b) the Required Lenders, and (c) if the rights or duties of Administrative Agent, the L/C Issuer, or the Swing Line Lender are affected thereby, Administrative Agent, the L/C Issuer, or the Swing Line Lender, as applicable; provided that: (i) no amendment or waiver pursuant to this Section 11.11 shall (A) increase any Commitment of any Lender without the consent of such Lender or (B) reduce the amount of or postpone the date for any scheduled payment of any principal of or interest on any Loan or of any Reimbursement Obligation or of any fee payable hereunder without the consent of the Lender to which such payment is owing or which has committed to make such Loan or Letter of Credit (or participate therein) hereunder; (ii) no amendment or waiver pursuant to this Section 11.11 shall, unless signed by each Lender, extend the Revolving Credit Termination Date, change the definition of Required Lenders, change the provisions of this Section 11.11, release any material guarantor or all or substantially all of the Collateral (except as otherwise provided for in the Loan Documents), or affect the number of Lenders required to take any action hereunder or under any other Loan Document; and (iii) no amendment to Section 10 shall be made without the consent of the Guarantor(s) affected thereby. Section 11.12 Headings. Section headings used in this Agreement are for reference only and shall not affect the construction of this Agreement. Section 11.13 Costs and Expenses; Indemnification. Borrower agrees to pay all reasonable out-of-pocket costs and expenses of Administrative Agent and the Left Lead Arranger in connection with the preparation, negotiation, syndication, and administration of the Loan Documents and the due diligence, examinations, appraisals, environmental analysis and other activities and other activities relating thereto, including, without limitation, including the reasonable fees and disbursements of counsel to Administrative Agent and the Left Lead Arranger, in connection with (i) the syndication and administration of the Credits, and (ii) the preparation, negotiation, administration, management, execution and delivery of the Loan Documents and in connection with the transactions contemplated hereby or thereby, and any amendment, waiver or consent related thereto, whether or not the transactions contemplated herein are consummated,

-104- 751970602 together with any fees and charges suffered or incurred by Administrative Agent or the Left Lead Arranger in connection with periodic environmental audits, fixed asset appraisals, title insurance policies, collateral filing fees and lien searches. Borrower agrees to pay to Administrative Agent, Lead Arrangers, the L/C Issuer and each Lender, and any other holder of any Obligations outstanding hereunder, all costs and expenses reasonably incurred or paid by Administrative Agent, Lead Arrangers, the L/C Issuer, such Lender, or any such holder, including reasonable attorneys’ fees (limited to one primary counsel to Administrative Agent, Lead Arrangers, the L/C Issuer and the Lenders and one firm of counsel in any relevant local jurisdiction, plus such additional counsel as may be necessary in the case of an actual or perceived conflict of interest) and disbursements and court costs, in connection with any Default or Event of Default hereunder (including an Event of Default under Section 8.1(j) or 8.1(k)) or in connection with the enforcement of any of the Loan Documents (including all such costs and expenses incurred in connection with any proceeding under the United States Bankruptcy Code involving Borrower or any Guarantor as a debtor thereunder). Borrower further agrees to indemnify Administrative Agent, the Lead Arrangers, the L/C Issuer, each Lender, and any security trustee therefor, and their respective Affiliates, directors, officers, employees, agents, financial advisors, and consultants (each such Person being called an “Indemnitee”) against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all reasonable fees and disbursements of counsel (limited to one primary counsel to Administrative Agent, the Lead Arrangers, the L/C Issuer and the Lenders and one firm of counsel in any relevant local jurisdiction, plus such additional counsel as may be necessary in the case of an actual or perceived conflict of interest) for any such Indemnitee and all reasonable expenses of litigation or preparation therefor, whether or not the Indemnitee is a party thereto, or any settlement arrangement arising from or relating to any such litigation) which any of them may pay or incur arising out of or relating to any Loan Document or any of the transactions contemplated thereby or the direct or indirect application or proposed application of the proceeds of any Loan or Letter of Credit, other than those which arise from the gross negligence, bad faith or willful misconduct of the party claiming indemnification. Borrower, promptly following demand by Administrative Agent, the Lead Arrangers, the L/C Issuer or a Lender or any Affiliate thereof at any time, shall reimburse Administrative Agent, the L/C Issuer, such Lender or such Affiliate for any legal or other expenses (including, without limitation, all reasonable fees and disbursements of counsel for any such Indemnitee, limited to one primary counsel to Administrative Agent, the Lead Arrangers, the L/C Issuer and the Lenders and one firm of counsel in any relevant local jurisdiction, plus such additional counsel as may be necessary in the case of an actual or perceived conflict of interest) incurred in connection with investigating or defending against any of the foregoing (including any settlement costs relating to the foregoing) except if the same is directly due to the gross negligence, bad faith or willful misconduct of the party to be indemnified. To the extent permitted by applicable law, neither Borrower nor any Guarantor shall assert, and each such Person hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or the other Loan Documents or any agreement or instrument contemplated hereby or thereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof. The obligations of Borrower under this Section shall survive the termination of this Agreement. (b) Borrower unconditionally agrees to forever indemnify, defend and hold harmless, and covenants not to sue for any claim for contribution against, each Indemnitee for any damages,

-105- 751970602 costs, loss or expense, including without limitation response, remedial or removal costs and all fees and disbursements of counsel for any such Indemnitee, arising out of (i) this Agreement or the other Loan Documents and the transactions contemplated hereby or thereby, (ii) any presence, release, threatened release or disposal of any hazardous or toxic substance or petroleum by Borrower or any Subsidiary or otherwise occurring on or with respect to its Property (whether owned or leased), (iii) the operation or violation of any Environmental Law, whether federal, state, or local, and any regulations promulgated thereunder, by Borrower or any Subsidiary or otherwise occurring on or with respect to its Property (whether owned or leased), (iv) any claim for personal injury or property damage in connection with Borrower or any Subsidiary or otherwise occurring on or with respect to its Property (whether owned or leased), and (v) the inaccuracy or breach of any environmental representation, warranty or covenant by Borrower or any Subsidiary made herein or in any other Loan Document evidencing or securing any Obligations or setting forth terms and conditions applicable thereto or otherwise relating thereto, except for damages arising from the bad faith, willful misconduct or gross negligence of the relevant Indemnitee. This indemnification shall survive the payment and satisfaction of all Obligations and the termination of this Agreement, and shall remain in force beyond the expiration of any applicable statute of limitations and payment or satisfaction in full of any single claim under this indemnification. This indemnification shall be binding upon the successors and assigns of the Borrower and shall inure to the benefit of each Indemnitee and its successors and assigns. Section 11.14 Set off. In addition to any rights now or hereafter granted under the Loan Documents or applicable law and not by way of limitation of any such rights, upon the occurrence of any Event of Default, each Lender, the L/C Issuer, each subsequent holder of any Obligation, and each of their respective affiliates, is hereby authorized by Borrower and each Guarantor at any time or from time to time, without notice to Borrower, any Guarantor or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, indebtedness evidenced by certificates of deposit, whether matured or unmatured, and in whatever currency denominated, but not including trust accounts) and any other indebtedness at any time held or owing by that Lender, L/C Issuer, subsequent holder, or affiliate, to or for the credit or the account of Borrower or such Guarantor, whether or not matured, against and on account of the Obligations of Borrower or such Guarantor to that Lender, L/C Issuer, or subsequent holder under the Loan Documents, including, but not limited to, all claims of any nature or description arising out of or connected with the Loan Documents, irrespective of whether or not (a) that Lender, L/C Issuer, or subsequent holder shall have made any demand hereunder or (b) the principal of or the interest on the Loans and other amounts due hereunder shall have become due and payable pursuant to Section 8 and although said obligations and liabilities, or any of them, may be contingent or unmatured.

The Loan Documents constitute the entire understanding of the parties thereto with respect to the subject matter thereof and any prior agreements, whether written or oral, with respect thereto are superseded hereby. Section 11.16 Governing Law. This Agreement and the other Loan Documents (except as otherwise specified therein), and any claim, controversy, dispute or cause of action (whether in contract, tort or otherwise) based upon, arising out of or relating to this Agreement or any Loan Document, and the rights and duties of the parties hereto, shall be governed by and construed and determined in accordance with the internal laws of the State of New York.

-106- 751970602 Section 11.17 Severability of Provisions. Any provision of any Loan Document which is unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction. The parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provision with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions.

Section 11.18 Excess Interest. Notwithstanding any provision to the contrary contained herein or in any other Loan Document, no such provision shall require the payment or permit the collection of any amount of interest in excess of the maximum amount of interest permitted by applicable law to be charged for the use or detention, or the forbearance in the collection, of all or any portion of the Loans or other obligations outstanding under this Agreement or any other Loan Document (“Excess Interest”). If any Excess Interest is provided for, or is adjudicated to be provided for, herein or in any other Loan Document, then in such event (a) the provisions of this Section shall govern and control, (b) neither Borrower nor any guarantor or endorser shall be obligated to pay any Excess Interest, (c) any Excess Interest that Administrative Agent or any Lender may have received hereunder shall, at the option of Administrative Agent, be (i) applied as a credit against the then outstanding principal amount of Obligations hereunder and accrued and unpaid interest thereon (not to exceed the maximum amount permitted by applicable law), (ii) refunded to Borrower, or (iii) any combination of the foregoing, (d) the interest rate payable hereunder or under any other Loan Document shall be automatically subject to reduction to the maximum lawful contract rate allowed under applicable usury laws (the “Maximum Rate”), and this Agreement and the other Loan Documents shall be deemed to have been, and shall be, reformed and modified to reflect such reduction in the relevant interest rate, and (e) neither Borrower nor any guarantor or endorser shall have any action against Administrative Agent or any Lender for any damages whatsoever arising out of the payment or collection of any Excess Interest. Notwithstanding the foregoing, if for any period of time interest on any of Borrower’s Obligations is calculated at the Maximum Rate rather than the applicable rate under this Agreement, and thereafter such applicable rate becomes less than the Maximum Rate, the rate of interest payable on Borrower’s Obligations shall remain at the Maximum Rate until the Lenders have received the amount of interest which such Lenders would have received during such period on Borrower’s Obligations had the rate of interest not been limited to the Maximum Rate during such period.
