understands that (A) the acquisition of neither the Class A Common Stock nor the Series B Preferred Stock has not been registered under the Securities Act in reliance on an exemption therefrom, and (B) that the shares of the
Class A Common Stock and the Series B Preferred Stock will, upon their acquisition by the Lenders at Closing, be characterized as “restricted securities” under state and federal securities laws and may not be sold, transferred,
offered for sale, pledged, hypothecated, or otherwise disposed of, except pursuant to an effective registration statement under the Securities Act or pursuant to an exemption from the registration requirements of the Securities Act, and in
compliance with applicable state and federal securities laws.

(d)    Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing that
such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the date of

the provisions of Section 6.01, Default Interest shall accrue and be payable hereunder whether or not previously required by the Administrative Agent. Payment or acceptance of the increased rates of interest provided for in
this Section 2.05(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of the Administrative Agent or any
Lender.

time be agreed between the Borrower and such Agent. 
 SECTION 2.07.    Increased Costs, Etc. (a) If,
due to either (i) the introduction of or any change in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the
force of law), there shall be any increase in the cost to any Lender of agreeing to make or of making, funding or maintaining Loans (excluding, for purposes of this Section 2.07, any such increased costs resulting from
(x) Taxes or Other Taxes (as to which Section 2.09 shall govern) and (y) changes in the basis or rate of taxation of overall net income or overall gross income by the United States or by the foreign jurisdiction
or state under the laws of which such Lender is organized or has its Lending Office or any political subdivision thereof), then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Administrative
Agent), pay to the Administrative Agent for the account of such Lender within 10 calendar days after receipt of an invoice from such Lender additional amounts sufficient to compensate such Lender for such increased cost. A certificate as to the
amount of such increased cost, submitted to the Borrower by such Lender, shall be conclusive and binding for all purposes, absent manifest error. 

(a)    If any Lender determines that compliance with any law or regulation or any guideline or request from any central
bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender and that the amount of such
capital is increased by or based upon the existence of such Lender’s commitment to make Loans and other commitments of such type (or similar Guaranteed Debts), then, upon demand by such Lender or such corporation (with a copy of such demand to
the Administrative Agent), the Borrower shall pay to the Administrative Agent for the account of such Lender within 10 calendar days after receipt of an invoice from such Lender from such Lender, additional amounts sufficient to compensate such
Lender in the light of such circumstances, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender’s commitment to make Loans. A certificate as to such amounts submitted to
the Borrower by such Lender shall be conclusive and binding for all purposes, absent manifest error.

 SECTION 2.08.    Payments and Computations. 

(a)    The Borrower shall make each payment hereunder and under the other Loan Documents, irrespective of any right of
counterclaim or set-off (except as otherwise provided in Section 2.10), not later than 11:00 A.M. (New York City time) on the day when due in Cash in U.S. dollars to the Administrative Agent at the
Administrative Agent’s Account in same day funds, with payments being received by the Administrative Agent after such time being deemed to have been received on the next succeeding Business Day. The Administrative Agent will promptly thereafter
cause like funds to be distributed (i) if such payment by the Borrower is in respect of principal, interest, commitment fees, letter of credit fees or any other Obligation then payable hereunder and under the other Loan Documents to more than
one Lender, to such Lenders for the account of their respective Lending Offices ratably in accordance with the amounts of such respective Obligations then payable to such Lenders and (ii) if such payment by the Borrower is in respect of any
Obligation then payable hereunder to one Lender, to such Lender for the account of its Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of
the information contained therein in the Register pursuant to Section 9.07(d), from and after the effective date of such Assignment and Acceptance, the Administrative Agent shall make all payments hereunder and under the other Loan Documents in
respect of the interest assigned thereby to the assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. 

(b)    Each Loan Party hereby authorizes each Lender and each of its Affiliates, if and to the extent any payment owed to
such Lender is not made when due hereunder or under the other Loan Documents, to charge from time to time, to the fullest extent permitted by law, against any or all of such Loan Party’s accounts with such Lender or such Affiliate any amount so
due. 
 (c)    All computations of interest based on the Eurodollar Rate and of commitment fees, letter of credit fees
and other fees and commissions shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such
interest, fees or commissions are payable. Each determination by the Administrative Agent of an interest rate, fee or commission hereunder shall be conclusive and binding for all purposes, absent manifest error. 

(d)    Whenever any payment hereunder or under the other Loan Documents shall be stated to be due on a day other than a
Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or commitment or letter of credit fee or commission, as the case may
be; provided, however, that, if such extension would cause payment of interest on or principal of Loans to be made in the next following calendar month, such payment shall be made on the preceding Business Day. 

(e)    Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment
is due to any Lender hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has

Page 53 of 161 

 
made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each such Lender on such due date
an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each such Lender shall repay to the Administrative Agent forthwith on demand such amount
distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Eurodollar Rate. 

(f)    If the Administrative Agent receives funds for application to the Obligations of the Loan Parties under or in
respect of the Loan Documents under circumstances for which the Loan Documents do not specify the Loans to which, or the manner in which, such funds are to be applied, the Administrative Agent may, if no instructions with respect thereto are
received from the Lenders upon request, but shall not be obligated to, elect to distribute such funds to each of the Lenders in accordance with such Lenders’ Pro Rata Share of the aggregate principal amount of all Loans outstanding at such
time, in repayment or prepayment of such of the outstanding Loans or other Obligations then owing to such Lender, for application to such principal repayment installments thereof, as the Administrative Agent shall direct. 

SECTION 2.09.    Taxes. (a) Any and all payments by any Loan Party to or for the account of any Lender or
any Agent hereunder or under any other Loan Document shall be made, in accordance with Section 2.08 or the applicable provisions of such other Loan Document, if any, free and clear of and without deduction for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender and each Agent, (x) taxes that are imposed on its overall net income by the
United States and taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof) by the state or foreign jurisdiction under the laws of which such Lender or such Agent, as the case may be, is organized (or any
political subdivision thereof), has its Lending Office, has a permanent establishment or is engaged in business (other than the business that the Lender is engaged in solely by reason of the transactions contemplated by this Agreement), (y) any
branch profits taxes imposed by the United States of America and (z) withholding taxes imposed under law in effect on the date hereof or at the time the Lender designates a new Lending Office, other than any new Lending Office designated at the
written request of a Loan Party (in the case of a Lender that is not an Initial Lender, this clause (z) shall include taxes imposed under law in effect on the date such Lender becomes a Lender, except to the extent that the Lender’s
predecessor would have been entitled to receive additional amounts under this Section 2.09(a)) and, in the case of each Lender, taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof)
by the state or foreign jurisdiction of such Lender’s Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities
in respect of payments hereunder or under any other Loan Document being hereinafter referred to as “Taxes”). If any Loan Party shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or
under any other Loan Document to any Lender or any Agent, (i) the sum payable by such Loan Party shall be increased as may be necessary so that after such Loan Party and the Administrative Agent have made all required deductions (including
deductions applicable to additional sums payable under this Section 2.09)

Page 54 of 161 

 
such Lender or such Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Loan Party shall make all such
deductions and (iii) such Loan Party shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. 

(a)    In addition, each Loan Party shall pay any present or future stamp, documentary, excise, property (including
intangible property, but with regard to all property taxes, only to the extent relating to property of a Loan Party) mortgage recording or similar taxes, charges or levies that arise from any payment made by such Loan Party hereunder or under any
other Loan Documents or from the execution, delivery or registration of, performance under, or otherwise with respect to, this Agreement or the other Loan Documents (hereinafter referred to as “Other Taxes”). 

(b)    The Loan Parties shall indemnify each Lender and each Agent for and hold them harmless against the full amount of
Taxes and Other Taxes, and for the full amount of taxes of any kind imposed or asserted by any jurisdiction on amounts payable under this Section 2.09, imposed on or paid by such Lender or such Agent (as the case may be)
and any liability (including penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within thirty (30) days from the date such Lender or such Agent (as the case may be)
makes written demand therefor. 
 (c)    Within 30 days after the date of any payment of Taxes, the appropriate Loan
Party shall furnish to the Administrative Agent, at its address referred to in Section 9.02, the original or a certified copy of a receipt evidencing such payment, to the extent such a receipt is issued therefor, or other
written proof of payment thereof that is reasonably satisfactory to the Administrative Agent. In the case of any payment hereunder or under the other Loan Documents by or on behalf of a Loan Party through an account or branch outside the United
States or by or on behalf of a Loan Party by a payor that is not a United States person, if such Loan Party determines that no Taxes are payable in respect thereof, such Loan Party shall furnish, or shall cause such payor to furnish, to the
Administrative Agent, at such address, an opinion of counsel acceptable to the Administrative Agent stating that such payment is exempt from Taxes. For purposes of subsections (d) and (e) of this
Section 2.09, the terms “United States” and “United States person” shall have the meanings specified in Section 7701 of the Internal Revenue Code. 

(d)    Each Lender organized under the laws of a jurisdiction outside the United States shall, on or prior to the date of
its execution and delivery of this Agreement in the case of each Initial Lender and on the date of the Assignment and Acceptance pursuant to which it becomes a Lender in the case of each other Lender, and from time to time thereafter as reasonably
requested in writing by the Borrower (but only so long thereafter as such Lender remains lawfully able to do so), provide each of the Administrative Agent and the Borrower with two original Internal Revenue Service Forms W-8BEN or W-8EC1 or (in the case of a Lender that has certified in writing to the Administrative Agent that it is not (i) a “bank” as defined in
Section 881(c)(3)(A) of the Internal Revenue Code), (ii) a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Internal Revenue Code) of any Loan Party or (iii) a
controlled foreign corporation related to any Loan Party (within the meaning of Section 864(d)(4) of the Internal

Revenue Code), Internal Revenue Service Form W-8BEN, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying
that such Lender is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or any other Loan Document or, in the case of a Lender that has certified that it is not a “bank” as
described above, certifying that such Lender is a foreign corporation, partnership, estate or trust. As provided in Section 2.09(a), if the forms provided by a Lender at the time such Lender first becomes a party to this
Agreement indicate a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and until such Lender provides the appropriate forms certifying that a lesser rate
applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes for periods governed by such forms; provided, however, that if, at the effective date of the Assignment and Acceptance pursuant to which a Lender
becomes a party to this Agreement, the Lender assignor was entitled to payments under subsection (a) of this Section 2.09 in respect of United States withholding tax with respect to interest paid
at such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Taxes) United States withholding tax, if any, applicable with respect to
the Lender assignee on such date. If any form or document referred to in this subsection (e) requires the disclosure of information, other than information necessary to compute the tax payable and information required on
the date hereof by Internal Revenue Service Form W-8BEN or W-8EC1 or the related certificate described above, that the applicable Lender reasonably considers to be
confidential, such Lender shall give notice thereof to the Borrower and shall not be obligated to include in such form or document such confidential information. 

(e)    For any period with respect to which a Lender has failed to provide the Borrower with the appropriate form,
certificate or other document described in subsection (e) above (other than if such failure is due to a change in law, or in the interpretation or application thereof, occurring after the date on which a form, certificate
or other document originally was required to be provided or if such form, certificate or other document otherwise is not required under subsection (e) above), such Lender shall not be entitled to indemnification under
subsection (a) or (c) of this Section 2.09 with respect to Taxes imposed by the United States by reason of such failure; provided, however, that should a Lender become subject to Taxes
because of its failure to deliver a form, certificate or other document required hereunder, the Loan Parties shall take such steps as such Lender shall reasonably request, at the Lender’s sole expense and as long as the Loan Parties determine
that such steps will not, in the reasonable judgment of the Loan Parties, be disadvantageous to the Loan Parties, to assist such Lender to recover such Taxes. 

(f)    Any Lender claiming any additional amounts payable pursuant to this Section 2.09 agrees
to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such
additional amounts that may thereafter accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. In addition, if a Lender determines, in such Lender’s sole discretion, that it has received a
refund or credit in respect of any Taxes or Other Taxes as to which it has been indemnified pursuant to Section 2.09(c), or with respect to which additional amounts

Page 56 of 161 

 
have been paid pursuant to Section 2.09(a), such Lender shall pay to the Borrower an amount equal to such refund (but such amount in no event to exceed the amount of any
indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.09 with respect to the Taxes or Other Taxes giving rise to such refund) net of all out-of-pocket expenses of such Lender, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that the Borrower, upon the request of
such Lender, shall agree to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to such Lender in the event such Lender subsequently determines that such refund or
credit is unavailable under applicable law or is otherwise required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require a Lender to rearrange its tax affairs or to make available its tax returns (or
any other information relating to its taxes that it deems confidential) to the Borrower or any other Person. 

SECTION 2.10.    Sharing of Payments, Etc. If any Lender shall obtain at any time any payment (whether
voluntary, involuntary, through the exercise of any right of set-off, or otherwise, other than as a result of an assignment pursuant to Section 9.07), (a) on account of Obligations
due and payable to such Lender hereunder and under the other Loan Documents in excess of its ratable share (according to the proportion of (i) the amount of such Obligations due and payable to such Lender to (ii) the aggregate amount of
the Obligations due and payable to all Lenders hereunder and under the other Loan Documents at such time) of payments on account of the Obligations due and payable to all Lenders hereunder and under the other Loan Documents at such time obtained by
all the Lenders at such time or (b) on account of Obligations owing (but not due and payable) to such Lender hereunder and under the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the
amount of such Obligations owing to such Lender at such time to (ii) the aggregate amount of the Obligations owing (but not due and payable) to all Lenders hereunder and under the other Loan Documents at such time) of payments on account of the
Obligations owing (but not due and payable) to all Lenders hereunder and under the other Loan Documents at such time obtained by all of the Lenders at such time, such Lender shall forthwith purchase from the other Lenders such interests or
participating interests in the Obligations as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from
such purchasing Lender, such purchase from each other Lender shall be rescinded and such other Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share (according to the proportion of
(i) the purchase price paid to such Lender to (ii) the aggregate purchase price paid to all Lenders) of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of
such other Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Loan Parties
agree that any Lender so purchasing an interest or participating interest from another Lender pursuant to this Section 2.10 may, to the fullest extent permitted by law, exercise all its rights of payment (including the
right of set-off) with respect to such interest or participating interest, as the case may be, as fully as if such Lender were the direct creditor of the Loan Parties in the amount of such interest or
participating interest, as the case may be.

 SECTION 2.11.    Use of Proceeds. The proceeds of the Loans
shall be available (and the Borrower agrees that it shall use such proceeds and Commitments), on the Effective Date, to (i) repay and/or refinance all Existing Debt (other than Permitted Existing Debt) of the Loan Parties, (ii) fund the
Initial Growth Capex Reserve Account in an amount equal to $42,076,973.27 (which amounts shall be used solely to fund Frac Fleet 16), (iii) pay accrued expenses and accounts payable and (iv) pay transaction fees and expenses contemplated under
the Facilities herein or under the ABL Facility. 
 SECTION 2.12.    Evidence of Debt. (a) Each Lender
shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan owing to such Lender from time to time, including the amounts of principal and interest
payable and paid to such Lender from time to time hereunder. The Borrower agrees that upon written notice by any Lender to the Borrower (with a copy of such notice to the Administrative Agent) to the effect that a promissory note or other evidence
of indebtedness is required or appropriate in order for such Lender to evidence (whether for purposes of pledge, enforcement or otherwise) the Loans owing to, or to be made by, such Lender, the Borrower shall promptly execute and deliver to such
Lender, with a copy to the Administrative Agent, a Term Loan A Notes and Term Loan B Notes, as applicable, in substantially the form of Exhibits A-1 and
A-2 hereto, as applicable, payable to the order of such Lender in a principal amount equal to the Loans of such Lender. All references to the Notes in the Loan Documents mean the Notes, if any, to the
extent issued hereunder. 
 (a)    The Register maintained by the Administrative Agent pursuant to
Section 9.07(d) shall include a control account, and a subsidiary account for each Lender, in which accounts (taken together) shall be recorded (i) the date and amount of each Borrowing made hereunder and, if
appropriate, the Eurodollar Rate Period applicable thereto, (ii) the terms of each Assignment and Acceptance delivered to and accepted by it, (iii) the amount of any principal or interest due and payable or to become due and payable from
the Borrower to each Lender hereunder and (iv) the amount of any sum received by the Administrative Agent from the Borrower hereunder and each Lender’s share thereof. 

(b)    Entries made in good faith by the Administrative Agent in the Register pursuant to
subsection (b) above, and by each Lender in its account or accounts pursuant to subsection (a) above, shall be prima facie evidence of the amount of principal and interest due and payable or
to become due and payable from the Borrower to, in the case of the Register, each Lender and, in the case of such account or accounts, such Lender, under this Agreement, absent manifest error; provided, however, that the failure of the
Administrative Agent or such Lender to make an entry, or any finding that an entry is incorrect, in the Register or such account or accounts shall not limit or otherwise affect the obligations of the Borrower under this Agreement. 

SECTION 2.13.    Duty to Mitigate. In the event that any Lender demands payment of costs or additional amounts
pursuant to Sections 2.07 or 2.09, the Borrower may, upon twenty (20) days’ prior written notice to such Lender and the Administrative Agent, elect to cause such Lender to assign its Loans and Commitments
in full to one or more Persons selected by the Borrower so long as (i) each such Person satisfies the criteria of an Eligible Assignee and is reasonably

(q)    Frac Fleet 16 Commercial Agreement. The Commercial Agreement described on Schedule 6.01(q) at any
time ceases to be valid and binding or in full force and effect or is terminated and no termination payment is paid by the counterparty to such Commercial Agreement in connection with such termination, 

then, and in any such event, the Administrative Agent (i) shall at the request, or may with the consent, of the Required Lenders, by notice to the
Borrower, declare the Commitments of each Lender and the obligation of each Lender to make Loans to be terminated, whereupon the same shall forthwith terminate and (ii) shall at the request, or may with the consent, of the Required Lenders, by
notice to the Borrower, declare the Loans, all interest thereon and all other amounts payable under this Agreement and the other Loan Documents to be forthwith due and payable,

whereupon the Loans, all such interest and all such amounts shall become and be forthwith due and payable, without presentment, demand, protest or further notice of any kind, all of which are
hereby expressly waived by the Borrower; provided, however, that, in the event of an actual or deemed entry of an order for relief with respect to the Borrower under the Bankruptcy Code, (x) the Commitments of each Lender and the
obligation of each Lender to make Loans shall automatically be terminated and (y) the Loans, all such interest and all such amounts shall automatically become and be due and payable, without presentment, demand, protest or any notice of any
kind, all of which are hereby expressly waived by the Borrower. For the avoidance of doubt, payment defaults may be cured within the applicable cure period, if any, by equity contributions from one or more members of the Borrower without limitation
as to the number of such cures. Upon any acceleration (whether elective or automatic) of the unpaid principal balance of any Loan pursuant to this Section 6.01 (including any acceleration upon the occurrence of an actual or
deemed entry of an order for relief with respect to any Loan Party under the Bankruptcy Code or any other Bankruptcy Law, including, without limitation, upon the occurrence of an Event of Default pursuant to Section 6.01(f)) during the Yield
Maintenance Period and the Call Premium Period, as applicable, the applicable Lender shall be entitled to, and the Borrower shall pay as liquidated damages (it being agreed that the amount of damages that such Lender will suffer in each case are
difficult to calculate) an amount equal to the Yield Maintenance Fee and Call Premium applicable to the principal balance of such Loan that has been accelerated, as the case may be, determined, in the case of a Loan, as if such Loan had been prepaid
on the date of the acceleration thereof, less any interest accrued and paid thereon and attributable to the period from the date of acceleration to the date of payment, in each case in addition to all other amounts (including any Exit Fee) due and
payable in respect of the Obligations hereunder. 
 SECTION 6.02.    Application of Funds. After the
exercise of remedies provided for in Section 6.01 (or after the Loans have automatically become immediately due and payable as set forth in Section 6.01), any amounts received on account of the
Obligations shall be applied by the Administrative Agent in the following order, subject to the Intercreditor Agreement: 
 First, to
payment of that portion of the Obligations constituting fees, indemnities, expenses and other amounts (including fees, charges and disbursements of counsel to the Administrative Agent and amounts payable under Article II) payable to the
Administrative Agent under this Agreement or any other Loan Document in its capacity as such; 
 Second, to payment of that portion
of the Obligations constituting fees, indemnities and other amounts (other than principal and interest) payable to the Lenders (including fees, charges and disbursements of counsel to the Lenders arising under the Loan Documents and amounts payable
under Article II), ratably among them in proportion to the respective amounts described in this clause Second payable to them; 

Third, to payment of that portion of the Obligations constituting interest on the Term A Loans arising under the Loan Documents,
ratably among the Term Loan A Lenders in proportion to the respective amounts described in this clause Third payable to them;

 Fourth, to payment of that portion of the Obligations constituting interest on the
Term B Loans arising under the Loan Documents, ratably among the Term Loan B Lenders in proportion to the respective amounts described in this clause Fourth payable to them; 

Fifth, to payment of that portion of the Obligations constituting unpaid principal of the Term A Loans and other Obligations relating
to the Term A Loans (including the Yield Maintenance Fee, the Exit Fee and the Call Premium), in each case, ratably among the Administrative Agent, the Term Loan A Lenders in proportion to the respective amounts described in this clause Fifth held
by them; 
 Sixth, to payment of that portion of the Obligations constituting unpaid principal of the Term B Loans, Secured Hedge
Agreements and Secured Bank Product Obligations (other than Secured Hedge Agreements) and other Obligations relating to the Term B Loans, Secured Hedge Agreements and Secured Bank Product Obligations (including the Yield Maintenance Fee, the Exit
Fee and the Call Premium), in each case, ratably among the Administrative Agent and the Term Loan B Lenders, the Hedge Banks and the Cash Management Banks in proportion to the respective amounts described in this clause Sixth held by them; 

Seventh, to payment of all other Obligations ratably among the Secured Parties; and 

Last, the balance, if any, after all of the Obligations have been indefeasibly paid in full, to the Borrower or as otherwise required
by applicable law. 
 Excluded Swap Obligations with respect to any Guarantor shall not be paid with amounts received from such Guarantor or its assets, but
appropriate adjustments shall be made with respect to payments from other Loan Parties to preserve the allocation to Obligations otherwise set forth above in this Section 6.02. 

Notwithstanding the foregoing, Obligations arising under Secured Cash Management Agreements and Secured Hedge Agreements shall be excluded from the
application described above if the Administrative Agent has not received a Secured Party Designation Notice, together with such supporting documentation as the Administrative Agent may request, from the applicable Cash Management Bank or Hedge Bank,
as the case may be. Each Cash Management Bank or Hedge Bank not a party to this Agreement that has given the notice contemplated by the preceding sentence shall, by such notice, be deemed to have acknowledged and accepted the appointment of the
Administrative Agent pursuant to the terms of Article VII hereof for itself and its Affiliates as if a “Lender” party hereto.

 ARTICLE VII 

THE AGENTS 

SECTION 7.01.    Authorization and Action. (a) Each Lender (in its capacity as a Lender) hereby appoints
and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement and the other Loan Documents as are delegated to the Administrative Agent by the terms hereof and
thereof, together with such powers and discretion as are reasonably incidental thereto. As to any matters not expressly provided for by the Loan Documents (including, without limitation, enforcement of the Obligations or collection of the
Obligations owing under the Loan Documents), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or
refraining from acting) upon the instructions of the Required Lenders, and such instructions shall be binding upon all Lenders and all holders of Notes; provided, however, that the Administrative Agent shall not be required to take any action
that exposes the Administrative Agent to personal liability or that is contrary to this Agreement or applicable law. Without limiting the generality of the foregoing, each Lender hereby authorizes and instructs the Administrative Agent to enter into
the documents to be entered into by the Administrative Agent expressly mentioned in Section 3.01. 

(a)    The Administrative Agent may execute any of its duties under this Agreement or any other Loan Document (including
for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Term Loan Collateral Documents or of exercising any rights and remedies thereunder at the direction of the Term Loan Collateral Agent) by or
through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such
duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agent, employee or attorney-in-fact that it selects in accordance with
the foregoing provisions of this Section 7.01(b) in the absence of the Administrative Agent’s gross negligence or willful misconduct. 

SECTION 7.02.    Administrative Agent’s Reliance, Etc. Neither the Administrative Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with the Loan Documents, except for its or their own gross negligence or willful misconduct. Without limitation
of the generality of the foregoing, the Administrative Agent: (a) may consult with legal counsel (including counsel for any Loan Party), independent public accountants and other experts selected by it and shall not be liable for any action
taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (b) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements,
warranties or representations (whether written or oral) made in or in connection with the Loan Documents; (c) shall not have any duty to ascertain or to inquire as to the performance, observance or satisfaction of any of the terms, covenants or
conditions of any Loan Document on the part of any Loan Party or the existence at any time of any Default under the Loan Documents or to inspect the property (including the books and records) of any Loan Party; (d) shall not be responsible to
any Lender for

the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any lien or security interest created or purported to be created
under or in connection with, any Loan Document or any other instrument or document furnished pursuant thereto; and (e) shall incur no liability under or in respect of any Loan Document by acting upon any notice, consent, certificate or other
instrument or writing (which may be by electronic communication) believed by it to be genuine and signed or sent by the proper party or parties. 

SECTION 7.03.    Agents and Affiliates. With respect to its Commitments, the Loans made by it and any Notes
issued to it, each Agent and its Affiliates shall have the same rights and powers under the Loan Documents as any other Lender and may exercise the same as though each were not an Agent or an Affiliate of an Agent; and the term
“Lender” or “Lenders” shall, unless otherwise expressly indicated, include each Agent and its Affiliates in their respective individual capacities. Each Agent and its Affiliates may accept deposits from, lend money
to, act as trustee under indentures of, accept investment banking engagements from and generally engage in any kind of business with, any Loan Party, any of its Subsidiaries and any Person that may do business with or own securities of any Loan
Party or any such Subsidiary, all as if such Agent was not an Agent and without any duty to account therefor to the Lenders. No Agent shall have any duty to disclose any information obtained or received by it or any of its Affiliates relating to any
Loan Party or any of its Subsidiaries to the extent such information was obtained or received in any capacity other than as such Agent. 

SECTION 7.04.    Lender Credit Decision. Each Lender acknowledges that it has, independently and without
reliance upon any Agent or any other Lender and based on the financial statements referred to in Section 3.01 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision
to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make
its own credit decisions in taking or not taking action under this Agreement. 

SECTION 7.05.    Indemnification. (a) Each Lender severally agrees to indemnify each Agent (to the extent
not promptly reimbursed by the Borrower and without limiting its obligation to do so) from and against such Lender’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against such Agent in any way relating to or arising out of the Loan Documents or any action taken or omitted by
such Agent under the Loan Documents (collectively, the “Indemnified Costs”); provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from such Agent’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent jurisdiction.
Without limitation of the foregoing, each Lender agrees to reimburse each Agent promptly upon demand for its ratable share of any costs and expenses (including, without limitation, reasonable fees and expenses of counsel) payable by the Borrower
under Section 9.04, to the extent that such Agent is not promptly reimbursed for such costs and expenses by the Borrower. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this
Section 7.05 applies whether any such investigation,

Page 118 of 161 

 
litigation or proceeding is brought by any Lender or any other Person. Each Agent is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and
otherwise apply any and all amounts it receives pursuant to the Loan Documents to or for the credit or the account of any Lender against any and all obligations of such Lender to such Agent now or hereafter existing under this
Section 7.05; provided that the foregoing sentence shall only apply if such Lender fails to promptly pay such obligation following such Agent’s written request for payment; provided further that any obligation a
Lender fails to promptly pay following the Agent’s written request for payment shall bear interest at the same rate as Default Interest and the Agent is authorized to set off against any such accrued interest in the manner described above. 

(a)    For purposes of Section 7.05(a), (i) each Lender’s ratable share of any amount shall
be determined, at any time, according to the sum of the aggregate principal amount of the Loans outstanding at such time and owing to such Lender. The failure of any Lender to reimburse any Agent promptly upon demand for its ratable share of any
amount required to be paid by the Lenders to such Agent as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse such Agent for its ratable share of such amount, but no Lender shall be responsible for the
failure of any other Lender to reimburse such Agent for such other Lender’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender hereunder, the agreement and obligations of each Lender contained
in this Section 7.05 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the other Loan Documents. 

SECTION 7.06.    Successor Administrative Agent. The Administrative Agent may resign at any time by giving
thirty (30) days’ written notice thereof to the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right, with (so long as no Event of Default has occurred and is continuing) the consent of the
Borrower (not to be unreasonably withheld or delayed), 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 thirty
(30) days after the retiring Administrative Agent’s giving of notice of resignation or the Required Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a
successor Administrative Agent, which shall be a commercial bank organized under the laws of the United States or of any State thereof and having a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Administrative Agent, and the
retiring Administrative Agent shall be discharged from its duties and obligations under the Loan Documents. If within forty-five (45) days after written notice is given of the retiring Administrative Agent’s resignation or removal under
this Section 7.06 no successor Administrative Agent shall have been appointed and shall have accepted such appointment, then on such forty-fifth (45th) day (a) the
retiring Administrative Agent’s resignation or removal shall become effective, (b) the retiring Administrative Agent shall thereupon be discharged from its duties and obligations under the Loan Documents and (c) the Required Lenders
shall thereafter perform all duties of the retiring Administrative Agent under the Loan Documents until such time,

if any, as the Required Lenders appoint a successor Agent as provided above. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent shall have
become effective, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. 

SECTION 7.07.    Term Loan Collateral Agent. Each of the Administrative Agent and the Lenders hereby
designates and appoints CLMG as Term Loan Collateral Agent under this Agreement and the other Loan Documents and authorizes CLMG, in the capacity of Term Loan Collateral Agent, to (A) execute, deliver and perform the obligations, if any, of the
Term Loan Collateral Agent, as applicable under this Agreement and each other Loan Document and (B) take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such
duties as are expressly delegated to the Term Loan Collateral Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto; provided, however, that the Term Loan
Collateral Agent shall not be required to take any action that exposes the Term Loan Collateral Agent to personal liability or that is contrary to this Agreement or applicable law. Without limiting the generality of the foregoing, each of the
Administrative Agent and the Lenders hereby authorizes and instructs CLMG, in the capacity of Term Loan Collateral Agent, to execute and deliver the documents to be entered into by the Term Loan Collateral Agent expressly mentioned in
Section 3.01, and, without limiting any of the provisions of this Agreement, CLMG, in the capacity of Term Loan Collateral Agent, shall continue to be bound by and entitled to all the benefits and protections of all
provisions of this Article VII (including the successor agent provisions) and Article IX as if set forth in full herein with respect thereto. 

SECTION 7.08.    Secured Cash Management Agreements and Secured Hedge Agreements. Except as
otherwise expressly set forth herein, no Cash Management Bank or Hedge Bank that obtains the benefit of the provisions of Section 6.02, the Guaranty or any Collateral by virtue of the provisions hereof, of the Term Loan
Security Agreement or any Term Loan Collateral Document shall have any right to notice of any action or to consent to, direct or object to any action hereunder or under any other Loan Document or otherwise in respect of the Collateral (including the
release or impairment of any Collateral) (or to notice of or to consent to any amendment, waiver or modification of the provisions hereof or of the Term Loan Security Agreement or any Term Loan Collateral Document) other than in its capacity as a
Lender and, in such case, only to the extent expressly provided in the Loan Documents. Notwithstanding any other provision of this Article VII to the contrary, the Administrative Agent shall not be required to verify the payment of, or that
other satisfactory arrangements have been made with respect to, Obligations arising under Secured Cash Management Agreements and Secured Hedge Agreements except to the extent expressly provided herein and unless the Administrative Agent has received
a Secured Party Designation Notice of such Obligations, together with such supporting documentation as the Administrative Agent may request, from the applicable Cash Management Bank or Hedge Bank, as the case may be. The Administrative Agent shall
not be required to verify the payment of, or that other satisfactory arrangements have

 SECTION 9.04.    Costs and Expenses. (a)The Borrower agrees
to pay on demand (i) all reasonable and documented out-of-pocket costs and expenses of each Agent in connection with the preparation, execution, delivery,
administration, modification and amendment of, or any consent or waiver under, the Loan Documents (including, without limitation, (A) all due diligence, collateral review, syndication, transportation, computer, duplication, appraisal, audit,
insurance, consultant, search, filing and recording fees and expenses and (B) the reasonable and documented fees and expenses of counsel for each Agent with respect thereto, with respect to advising such Agent as to its rights and
responsibilities, or the perfection, protection or preservation of rights or interests, under the Loan Documents, with respect to negotiations with any Loan Party or with other creditors of any Loan Party or any of its Subsidiaries arising out of
any Default or any events or circumstances that may give rise to a Default and with respect to presenting claims in or otherwise participating in or monitoring any bankruptcy, insolvency or other similar proceeding involving creditors’ rights
generally and any proceeding ancillary thereto) and (ii) all costs and expenses of each Agent and each Lender in connection with the enforcement of the Loan Documents, whether in any action, suit or litigation, or any bankruptcy, insolvency or
other similar proceeding affecting creditors’ rights generally (including, without limitation, the reasonable fees and expenses of counsel for the Administrative Agent and each Lender with respect thereto). 

(a)    The Borrower agrees to indemnify, defend and save and hold harmless each Agent, each Lender, each of their
Affiliates and the respective officers, directors, employees, trustees, agents and advisors of each of the foregoing (each, an “Indemnified Party”) from and against, and shall pay on demand, any and all claims, damages,
losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of

any way to any Loan Party or any of its Subsidiaries, except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to
have resulted from such Indemnified Party’s gross negligence or willful misconduct. In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 9.04(b) applies, such indemnity
shall be effective whether or not such investigation, litigation or proceeding is brought by any Loan Party, its directors, shareholders or creditors, any Indemnified Party or any other Person, whether or not any Indemnified Party is otherwise a
party thereto and whether or not the transactions contemplated thereby are consummated. The Borrower also agrees not to assert any claim against any Agent, any Lender or any of their Affiliates, or any of their respective officers, directors,
employees, trustees, agents and advisors, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to the Facilities, the actual or proposed use of the proceeds of the Loans, the Loan
Documents or any of the transactions contemplated by the Loan Documents.

 (b)    If (i) any payment of principal of any Loan is made by the
Borrower to or for the account of a Lender other than on the last day of the Interest Period for such Loan as a result of (A) acceleration of the maturity of the Loans pursuant to Section 6.01 or (B) a mandatory
prepayment of the Loans pursuant to Section 2.04(b), or (ii) the Borrower fails to make any payment or prepayment of a Loan after the Borrower had delivered a notice of prepayment, whether, in the case of this
clause (ii), pursuant to Section 2.03 or 6.01 or otherwise, the Borrower shall, upon demand by such Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the
account of such Lender any amounts required to compensate such Lender for any additional losses, costs or expenses that it may reasonably incur as a result of such payment or such failure to pay or prepay, as the case may be, including, without
limitation, any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Loan. 

(c)    If any Loan Party fails to pay when due any costs, expenses or other amounts payable by it under any Loan Document,
including, without limitation, fees and expenses of counsel and indemnities or insurance premiums on account of insurance required hereunder, such amount may be paid on behalf of such Loan Party by the Administrative Agent or any Lender, in its sole
discretion. The Borrower agrees to pay all such amounts on demand. 
 (d)    Without prejudice to the survival of any
other agreement of any Loan Party hereunder or under any other Loan Document, the agreements and obligations of the Borrower contained in Sections 2.07 and 2.09 and this Section 9.04 shall
survive the payment in full of principal, interest and all other amounts payable hereunder and under any of the other Loan Documents. 

SECTION 9.05.    Right of Set-off. Upon (a) the occurrence and
during the continuance of any Event of Default and (b) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Loans due and payable
pursuant to the provisions of Section 6.01, each Agent and each Lender and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and
otherwise apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Agent, such Lender or such Affiliate to or for the credit or the account of the
Borrower against any and all of the Obligations of the Borrower now or hereafter existing under the Loan Documents, irrespective of whether such Agent or such Lender shall have made any demand under this Agreement and although such Obligations may
be unmatured. Each Agent and each Lender agrees promptly to notify the Borrower after any such set-off and application; provided, however, that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of each Agent and each Lender and their respective Affiliates under this Section 9.05 are in addition to other rights and remedies
(including, without limitation, other rights of set-off) that such Agent, such Lender and their respective Affiliates may have. 

SECTION 9.06.    Binding Effect. This Agreement shall become effective when it shall have been executed by the

been notified by each initial Lender that such initial Lender has executed it and thereafter shall be binding upon and inure to the benefit of the Loan Parties, each Agent and each Lender and
their respective successors and permitted assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of each Lender. This Agreement is intended to be solely for
the benefit of the parties hereto and is not intended to confer any benefits upon, or create any rights in favor of, any person other than the parties hereto. 

SECTION 9.07.    Assignments and Participations. (a) Each Lender may assign to one or more Eligible
Assignees all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment or Commitments, the Loans owing to it, and the Note or Notes held by it); provided,
however, that (i) each such assignment shall be of a uniform, and not a varying, percentage of all rights and obligations under and in respect of the Facilities, (ii) except in the case of an assignment to a Person that, immediately
prior to such assignment, was a Lender, an Affiliate of any Lender or an Approved Fund of any Lender or an assignment of all of a Lender’s rights and obligations under this Agreement, the aggregate amount of the Commitments being assigned to
such Eligible Assignee pursuant to such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $2,000,000 (or such lesser amount as shall be approved by the
Administrative Agent and, so long as no Default shall have occurred and be continuing at the time of effectiveness of such assignment, the Borrower), (iii) each such assignment shall be to an Eligible Assignee, (iv) no such assignments shall be
permitted without the written consent of the Administrative Agent, which consent shall not be unreasonably withheld, and (v) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and
recording in the Register, an Assignment and Acceptance, together with any Note or Notes (if any) subject to such assignment. 

(a)    Upon such execution, delivery, acceptance and recording, from and after the effective date specified in such
Assignment and Acceptance, (i) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a
Lender hereunder and (ii) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (other than its rights under
Sections 2.07, 2.09 and 9.04 to the extent any claim thereunder relates to an event arising prior to such assignment) and be released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all of the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto). 

(b)    By executing and delivering an Assignment and Acceptance, each Lender assignor thereunder and each assignee
thereunder confirm to and agree with each other and the other parties thereto and hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations made in or in connection with any Loan Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of
any lien or security interest

created or purported to be created under or in connection with, any Loan Document or any other instrument or document furnished pursuant thereto; (ii) such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to the financial condition of any Loan Party or the performance or observance by any Loan Party of any of its obligations under any Loan Document or any other instrument or
document furnished pursuant thereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.01 and such other documents and
information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon any Agent, such assigning Lender or any other
Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible
Assignee; (vi) such assignee appoints and authorizes each Agent to take such action as agent on its behalf and to exercise such powers and discretion under the Loan Documents as are delegated to such Agent by the terms hereof and thereof,
together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are required to be
performed by it as a Lender. 
 (c)    The Administrative Agent, acting for this purpose (but only for this purpose) as
the agent of the Borrower, shall maintain at its address referred to in Section 9.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of
the Lenders and the Commitment under each Facility of, and principal amount of the Loans owing under each Facility to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and
binding for all purposes, absent manifest error, and the Borrower, the Agents and the Lenders shall treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available
for inspection by the Borrower or any Agent or any Lender at any reasonable time and from time to time upon reasonable prior notice. 

(d)    Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee, together with any
Note or Notes (if any) subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit C hereto, (i) accept such Assignment and Acceptance,
(ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower and each other Agent. In the case of any assignment by a Lender, within five Business Days after its receipt of such notice,
the Borrower, at its own expense, shall execute and deliver to the Administrative Agent in exchange for the surrendered Note or Notes (if any) an amended and restated Note (which shall be marked “Amended and Restated”) to the order
of such Eligible Assignee in an amount equal to the Commitment assumed by it under each Facility pursuant to such Assignment and Acceptance and, if any assigning Lender that had a Note or Notes prior to such assignment has retained a Commitment
hereunder under such Facility, an amended and restated Note to the order of such assigning Lender in an amount equal to the Commitment retained by it hereunder. Such amended and restated Note or Notes shall be dated the effective date of such
Assignment and Acceptance and shall otherwise be in substantially the form of Exhibit A-1 or A-2 hereto, as the case may be.

 (e)    Each Lender may sell participations to one or more Persons (other
than any Loan Party or any of its Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitments, the Loans owing to it and the Note or Notes (if any) held
by it); provided, however, that (i) such Lender’s obligations under this Agreement (including, without limitation, its Commitments) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Note for all purposes of this Agreement, (iv) the Borrower, the Agents and the other Lenders shall continue to deal solely and directly
with such Lender in connection with such Lender’s rights and obligations under this Agreement and (v) no participant under any such participation shall have any right to approve any amendment or waiver of any provision of any Loan
Document, or any consent to any departure by any Loan Party therefrom. 
 (f)    Any Lender may, in connection with any
assignment or participation or proposed assignment or participation pursuant to this Section 9.07, disclose to the assignee or participant or proposed assignee or participant any information relating to the Borrower
furnished to such Lender by or on behalf of the Borrower; provided, however, that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree to preserve the confidentiality of any Confidential
Information received by it from such Lender. 
 (g)    Notwithstanding any other provision set forth in this Agreement,
any Lender may at any time create a security interest in all or any portion of its rights under this Agreement (including, without limitation, the Loans owing to it and the Note or Notes (if any) held by it) in favor of any Federal Reserve Bank or
Federal Home Loan Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System or similar laws and regulations relating to the Federal Home Loan Banks. 

(h)    Notwithstanding anything to the contrary contained herein, any Lender that is a Fund may, without the consent of
the Borrower or any other Person, create a security interest in all or any portion of the Loans owing to it and any Note or Notes held by it to the trustee for holders of obligations owed, or securities issued, by such Fund as security for such
obligations or securities; provided that, unless and until such trustee actually becomes a Lender in compliance with the other provisions of this Section 9.07, (i) no such pledge shall release the pledging Lender from any
of its obligations under the Loan Documents and (ii) such trustee shall not be entitled to exercise any of the rights of a Lender under the Loan Documents even though such trustee may have acquired ownership rights with respect to the pledged
interest through foreclosure or otherwise. 
 (i)    Notwithstanding anything herein to the contrary, 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 all or a portion of its
rights and obligations under this Agreement to such Person, unless (i) the

Page 129 of 161 

 
Borrower has consented to such assignment in writing in its sole and absolute discretion, or (ii) an Event of Default has occurred and is continuing. For the avoidance of doubt, with respect
to any assignee that becomes a Disqualified Institution after the applicable Trade Date (including as a result of the delivery of a notice pursuant to, and/or the expiration of the notice period referred to in, the definition of
“Disqualified Institution”), (A) such assignee shall not retroactively be disqualified from becoming a Lender and (B) the execution by the 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 in violation of this Section 9.07(j) shall not be void, but the provisions of Section 9.07(k),
9.07(l) and 9.07(m) below shall apply. 
 (j)    If any assignment or participation is made to any
Disqualified Institution without the Borrower’s prior written consent in violation of Section 9.07(j), 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 Agents, (i) terminate any Commitment of such Disqualified Institution and repay all Obligations of the Borrower owing to such Disqualified Institution in
connection with such Commitment, (ii) in the case of outstanding Loans held by Disqualified Institutions, purchase or prepay such Loans by paying the lesser of (A) the principal amount thereof and (B) the amount that such Disqualified
Institution paid to acquire such Loans, in each case plus accrued interest, accrued fees and all other amounts (other than principal amounts) payable to it hereunder and/or (C) require such Disqualified Institution to assign, without recourse
(in accordance with and subject to the restrictions contained in this Section 9.07), all of its interest, rights and obligations under this Agreement to one or more Eligible Assignees 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 of such Loans, in each case plus accrued interest, accrued fees and all other amounts (other than principal amounts)
payable to it hereunder. 
 (k)    Notwithstanding anything to the contrary contained in this Agreement, Disqualified
Institutions (i) will not (A) have the right to receive information, reports or other materials provided to Lenders by the Borrower, the Administrative Agent, the Term Loan Collateral Agent or any Lender, (B) attend or participate in
meetings attended by the Lenders and any of the Agents, or (C) access any electronic site established for the Lenders or confidential communications from counsel to or financial advisors of the Administrative Agent, the Term Loan Collateral
Agent or the Lenders and (ii) (A) 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, the Term Loan Collateral 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 limited to consenting to the matters specified in Section 9.07 (a)(i)(B),
Section 9.07 (a)(i)(G) or Section 9.07 (a)(ii) and will be deemed to have consented in the same proportion as the Lenders that are not Disqualified Institutions consented to such matter, and
(B) for purposes of voting on any plan of reorganization or plan of liquidation pursuant to the Bankruptcy Code or any similar law (a “Plan of Reorganization”), each Disqualified Institution party hereto hereby agrees
(x) not to vote on such Plan of Reorganization, (y) if such Disqualified Institution does vote on such Plan of Reorganization notwithstanding the restriction in the foregoing clause (x), such

vote will be deemed not to be in good faith and shall be “designated” pursuant to Section 1126(e) of the Bankruptcy Code (or any similar provision in any other Bankruptcy Laws),
and such vote shall not be counted in determining whether the applicable class has accepted or rejected such Plan of Reorganization in accordance with Section 1126(c) of the Bankruptcy Code (or any similar provision in any other Bankruptcy
Laws) and (z) not to contest any request by any party for a determination by a bankruptcy court (or other applicable court of competent jurisdiction) effectuating the foregoing clause (y). 

(l)    The Administrative Agent shall have the right, and the Borrower hereby expressly authorizes the Administrative
Agent, to provide the list of Disqualified Institutions provided by the Borrower and any updates thereto from time to time (collectively, the “DQ List”) to each Lender requesting the same. 

(m)    The Administrative Agent and the Lenders 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, neither the Administrative Agent nor any Lender shall (i) be obligated
to ascertain, monitor or inquire as to whether any other Lender or participant or prospective Lender or participant is a Disqualified Institution or (ii) have any liability with respect to or arising out of any assignment or participation of
Loans or Commitments, or disclosure of confidential information, by any other Person to any Disqualified Institution. 

SECTION 9.08.    Execution in Counterparts. This Agreement may be executed in any number of counterparts and
by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery by electronic communication of an executed
counterpart of a signature page to this Agreement shall be effective as delivery of an original executed counterpart of this Agreement. 

SECTION 9.09.    Confidentiality. Neither any Agent nor any Lender shall disclose any Confidential Information
to any Person without the consent of the Borrower, other than (a) to such Agent’s or such Lender’s Affiliates and their officers, directors, employees, trustees, agents and advisors who have a need to know as a result of being
involved in the Facilities and then only on the condition that such matters may not be further disclosed and to actual or prospective Eligible Assignees and participants, and then only on a confidential basis, (b) as required by any law, rule
or regulation or judicial process, (c) as requested or required by any state, Federal or foreign authority or examiner (including the National Association of Insurance Commissioners or any similar organization or quasi-regulatory authority)
regulating such Lender, (d) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Loan
Parties received by it from such Lender, (e) in connection with any litigation or proceeding to which such Agent or such Lender or any of its Affiliates may be a party or (f) in connection with the exercise of any right or remedy under
this Agreement or any other Loan Document. Each party hereto acknowledges that money damages would not be a sufficient remedy for any breach of the confidentiality provisions contained in this Section 9.09 by such party and
that the other party

would suffer irreparable harm as a result of any such breach. Accordingly, each party will also be entitled to equitable relief, including injunction and specific performance, as a remedy for any
breach or threatened breach of the confidentiality provisions contained in this Section 9.09 by the other party. Subject to the limitations contained in Section 9.15, the equitable remedies
referred to above will not be deemed to be the exclusive remedies for a breach of the confidentiality provisions in this Section 9.09. 

SECTION 9.10.    Marshalling; Payments Set Aside. Neither any Agent nor any Lender shall be under any
obligation to marshal any assets in favor of any Loan Party or any other Person or against or in payment of any or all of the Obligations. To the extent that any Loan Party makes a payment or payments to the Administrative Agent or the Lenders (or
to Administrative Agent, on behalf of the Lenders), or any Agent or Lender enforces any security interests or exercise its rights of setoff, and such payment or payments or the proceeds of such enforcement or setoff or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other party under any Bankruptcy Law, any other state or federal law, common law or any equitable cause, then,
to the extent of such recovery, the obligation or part thereof originally intended to be satisfied, and all Liens, rights and remedies therefor or related thereto, shall be revived and continued in full force and effect as if such payment or
payments had not been made or such enforcement or setoff had not occurred. 
 SECTION 9.11.    Patriot Act
Notice. Each Lender and each Agent (for itself and not on behalf of any Lender) hereby notifies the Loan Parties that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies each
Loan Party, which information includes the name and address of such Loan Party and other information that will allow such Lender or such Agent, as applicable, to identify such Loan Party in accordance with the Patriot Act. Each Loan Party shall, and
shall cause each of its Subsidiaries to, provide such information and take such actions as are reasonably requested by any Agent or any Lender in order to assist the Agents and the Lenders in maintaining compliance with the Patriot Act. 

SECTION 9.12.    Jurisdiction, Etc. (a) Each of the parties hereto hereby irrevocably and unconditionally
submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or Federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding
arising out of or relating to this Agreement or any of the other Loan Documents to which it is a party, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims
in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the fullest extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Except as provided in Section 9.15, nothing in this Agreement shall affect any right
that any party may otherwise have to bring any action or proceeding relating to this Agreement or any of the other Loan Documents in the courts of any jurisdiction.

 (a)    Each of the parties hereto irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any of the other Loan
Documents to which it is a party in any New York State or Federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court. 
 SECTION 9.13.    Governing Law. This Agreement and the Notes shall be
governed by, and construed in accordance with, the laws of the State of New York. 
 SECTION 9.14.    Waiver of
Jury Trial. Each of the Loan Parties, the Agents and the Lenders irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to any of the Loan
Documents, the Loans or the actions of any Agent or any Lender in the negotiation, administration, performance or enforcement thereof. 

SECTION 9.15.    Limitation on Liability. TO THE EXTENT PERMITTED BY APPLICABLE LAW, AND NOTWITHSTANDING ANY
OTHER PROVISION OF THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS: (A) NONE OF THE ADMINISTRATIVE AGENT, THE LENDERS OR ANY INDEMNIFIED PARTY SHALL BE LIABLE TO ANY PARTY FOR ANY INDIRECT, SPECIAL, PUNITIVE OR CONSEQUENTIAL DAMAGES IN CONNECTION
WITH THEIR RESPECTIVE ACTIVITIES RELATED TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, THE TRANSACTIONS CONTEMPLATED THEREBY, THE LOANS, OR OTHERWISE IN CONNECTION WITH THE FOREGOING; (B) WITHOUT LIMITING THE FOREGOING, NONE OF THE
ADMINISTRATIVE AGENT, THE LENDERS OR ANY INDEMNIFIED PARTY SHALL BE SUBJECT TO ANY EQUITABLE REMEDY OR RELIEF, INCLUDING SPECIFIC PERFORMANCE OR INJUNCTION ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, OR THE TRANSACTIONS
CONTEMPLATED THEREBY; (C) NONE OF THE ADMINISTRATIVE AGENT, THE LENDERS OR ANY INDEMNIFIED PARTY SHALL HAVE ANY LIABILITY TO THE LOAN PARTIES, FOR DAMAGES OR OTHERWISE, ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, OR
THE TRANSACTIONS CONTEMPLATED THEREBY UNTIL THE EFFECTIVE DATE HAS OCCURRED; AND (D) IN NO EVENT SHALL LENDERS’ LIABILITY TO THE LOAN PARTIES FOR FAILURE TO FUND ANY LOAN EXCEED ACTUAL DIRECT DAMAGES INCURRED BY THE LOAN PARTIES OF UP TO
$10,000,000 IN THE AGGREGATE. 
 SECTION 9.16.    Acceptable Purchaser Schedule Updates . The parties hereto
agree that either the Administrative Agent (on behalf of the Lenders) or the Borrower may request, upon 10 Business Days written notice, a modification to Schedule II to this Agreement, substantially in the form of Exhibit J, to add or
delete a Person from such schedule of Acceptable Purchasers (each such notice, a “Proposed Acceptable Purchaser Update”). Prior to the proposed date for addition or deletion set forth in the Proposed Acceptable Purchaser
Update, the Administrative Agent or

the Borrower (as applicable) shall approve or reject such proposed update (such approval not to be unreasonably withheld). In the event such change is approved, Schedule II shall be
updated as of such date for purposes of this Agreement.

Responsibility. In connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document), the Borrower acknowledges and agrees, and
acknowledges its Affiliates’ understanding, that: (a)(i) the arranging and other services regarding this Agreement provided by the Administrative Agent and any Affiliate thereof, and the Lenders are

 NOW, THEREFORE, in consideration of the agreements hereinafter set forth, and for other good and
valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows: 
 ARTICLE I

1.4    Amendment to Section 2.01.
Section 2.01 is hereby amended and restated in its entirety as follows: 
 “2.01 The
Loans. Subject to the terms and conditions set forth herein, each Lender severally agrees to make loans (each such loan, a “Revolving Credit Loan”) to the Borrower from time to time, on any Business Day during the Availability

Section 2.01, prepay under Section 2.05, and reborrow under this Section 2.01. Revolving Credit Loans may be Base Rate Loans or LIBOR Loans, as further provided herein;
provided, however, any Revolving Credit Borrowings made on the Closing Date or any of the three (3) Business Days following the Closing Date shall be made as Base Rate Loans unless the Borrower delivers a funding indemnity letter
reasonably acceptable to the Administrative Agent not less than three (3) Business Days prior to the date of such Revolving Credit Borrowing.” 

  
 4
