(b) The Borrowers unconditionally promise to repay all outstanding Revolving Loans on the Maturity Date for the Revolving Facility.

  
 30 

 Section 2.05. Procedure for Revolving Loan Borrowing. The Borrowers may borrow
under the Revolving Commitments during the Revolving Commitment Period on any Business Day, provided that the Borrower Representative shall give the Administrative Agent irrevocable notice in the form of a Notice of Borrowing or by telephone (which
notice must be received by the Administrative Agent prior to 11:00 A.M., Dallas, Texas time, (a) three (3) Business Days prior to the requested Borrowing Date, in the case of Eurodollar Loans, or (b) one (1) Business Day prior to
the requested Borrowing Date, in the case of CBFR Loans), specifying (i) the amount and Type of Revolving Loans to be borrowed, (ii) the requested Borrowing Date, and (iii) in the case of Eurodollar Loans, the respective amounts of
each such Type of Loan and the respective lengths of the initial Interest Period therefor. Each telephonic notice of a borrowing under the Revolving Facility shall be confirmed on the Business Day following such notice by delivery to the
Administrative Agent of a properly completed Notice of Borrowing signed by the Borrower Representative. Any Revolving Loans made on the Closing Date shall initially be CBFR Loans. Each borrowing under the Revolving Commitments shall be in an amount
equal to (x) in the case of CBFR Loans, $500,000 or a whole multiple of $100,000 in excess thereof (or, if the then aggregate Available Revolving Commitments are less than $500,000, such lesser amount) and (y) in the case of Eurodollar
Loans, $1,000,000 or a whole multiple of $500,000 in excess thereof (or, if the then aggregate Available Revolving Commitments are less than $1,000,000, such lesser amount). Upon receipt of any such notice from the Borrower Representative, the
Administrative Agent shall promptly notify each Revolving Lender thereof. Each Revolving Lender will make the amount of its Applicable Revolving Percentage of each borrowing available to the Administrative Agent for the account of the Borrowers at
the Funding Office prior to 1:00 P.M., Dallas, Texas time, on the Borrowing Date requested by the Borrower Representative in funds immediately available to the Administrative Agent. Such borrowing will then be made available to the Borrower
Representative by the Administrative Agent crediting the account of the Borrower Representative on the books of such office with the aggregate of the amounts made available to the Administrative Agent by the Revolving Lenders and in like funds as
received by the Administrative Agent. The Borrowers agree that the Borrowers shall bear all risk of loss resulting from Revolving Loans made pursuant to any borrowing request made by telephone. 

Section 2.06. Commitment Fees. The Borrowers agree to pay to the Administrative Agent for the account of each Revolving
Lender a commitment fee for the period from and including the Closing Date to the last day of the Revolving Commitment Period, computed at the Commitment Fee Rate on the average daily amount of the Available Revolving Commitment of such Lender
during the period for which payment is made, payable quarterly in arrears on the last day of each March, June, September and December and on the Revolving Termination Date, commencing on December 31, 2012. 

Section 2.07. Termination or Reduction of Revolving Commitments. The Borrowers shall have the right, upon not less than three
(3) Business Days’ notice by the Borrower Representative to the Administrative Agent, to terminate the Revolving Commitments or, from time to time, to reduce the amount of the Revolving Commitments; provided that no such termination
or reduction of Revolving Commitments shall be permitted if, after giving effect thereto and to any prepayments of the Revolving Loans made on the effective date thereof, the Aggregate Outstanding Revolving Credit would exceed the Total Revolving
Commitments; provided, further, that any such notice of reduction of the Revolving Commitments may be 

  
 31 

 
conditioned upon the effectiveness of other credit facilities or the closing of an acquisition or divestiture transaction, in which case such notice may be revoked by the Borrower Representative.
Any such reduction shall be in an amount equal to $1,000,000, or a whole multiple thereof, and shall reduce permanently the Revolving Commitments then in effect. All fees in respect of the Revolving Facility accrued until the effective date of any
termination of the Revolving Facility shall be paid on the effective date of such termination.

Prepayments. The Borrowers may at any time and from time to time prepay the Loans, in whole or in part, without premium or penalty, upon irrevocable notice delivered by the Borrower Representative to the Administrative Agent at least three
(3) Business Days prior thereto in the case of Eurodollar Loans and at least one (1) Business Day prior thereto in the case of CBFR Loans, which notice shall specify the date and amount of prepayment and whether the prepayment is
(a) of Revolving Loans or Term Loans or a combination thereof, and in the case of a combination thereof, the amount allocable to each, and (b) of Eurodollar Loans or CBFR Loans or a combination thereof; provided, that if a
Eurodollar Loan is prepaid on any day other than the last day of the Interest Period applicable thereto, the Borrowers shall also pay any amounts owing pursuant to Section 2.20. Upon receipt of any such notice the Administrative Agent shall
promptly notify each relevant Lender thereof. If any such notice is given, the amount specified in such notice shall be due and payable on the date specified therein, together with accrued interest to such date on the amount prepaid, provided
that any such notice may be conditioned upon the effectiveness of other credit facilities or the closing of an acquisition or divestiture transaction, in which case such notice may be revoked by the Borrower Representative. Partial prepayments of
Term Loans and Revolving Loans shall be in an aggregate principal amount of $500,000 or a whole multiple thereof Each prepayment of the Term Loans pursuant to this Section 2.08 shall be applied to the Term Loans in accordance with
Section 2 .15 (b). 
 Section 2.09. Mandatory Prepayments and Commitment Reductions. 

(a) If any Indebtedness (excluding any Indebtedness incurred in accordance with Section 6.02), shall be issued or incurred by any
Borrower, an amount equal to 100% of the Net Cash Proceeds thereof shall be applied on the date of such issuance or incurrence toward the prepayment of the Term Loans as set forth in Section 2.09(c). 

(b) If on any date any Borrower shall receive Net Cash Proceeds from any Asset Sale or Recovery Event then, unless a Reinvestment Notice
shall be delivered in respect thereof, such Net Cash Proceeds shall be applied on such date toward the prepayment of the Term Loans as set forth in Section 2.09(c); provided, that, (i) the aggregate Net Cash Proceeds of Asset Sales
and Recovery Events that may be excluded from the foregoing requirement pursuant to a Reinvestment Notice shall not exceed $500,000 in any Fiscal Year and (ii) on each Reinvestment Prepayment Date, an amount equal to the Reinvestment Prepayment
Amount with respect to the relevant Reinvestment Event shall be applied toward the prepayment of the Term Loans and the reduction of the Revolving Commitments as set forth in Section 2.09(c). 

(c) Amounts to be applied in connection with prepayments made pursuant to paragraph (a) or (b) of this Section 2.09 shall
be applied to the Term Loans in accordance with Section 2.15(b). Each prepayment of the Loans pursuant to paragraph (a) or (b) of this Section 2.09 shall be accompanied by accrued interest to the date of such prepayment on the amount
prepaid. 

  
 32 

 (d) If for any reason the Aggregate Outstanding Revolving Credit at any time exceeds the
Total Revolving Commitments then outstanding, the Borrowers shall immediately prepay the Revolving Loans in an aggregate amount equal to such excess. 
 Section 2.10. Conversion and Continuation Options. 
 (a) The Borrowers
may elect from time to time to convert Eurodollar Loans under the Revolving Facility to CBFR Loans under the Revolving Facility by causing the Borrower Representative to give the Administrative Agent at least two (2) Business Days’ prior
irrevocable notice of such election pursuant to a Notice of Conversion/Continuation, provided that any such conversion of Eurodollar Loans may only be made on the last day of an Interest Period with respect thereto. The Borrowers may elect
from time to time to convert CBFR Loans under the Revolving Facility to Eurodollar Loans under the Revolving Facility by causing the Borrower Representative to give the Administrative Agent at least three (3) Business Days’ prior
irrevocable notice of such election pursuant to a Notice of Conversion/Continuation (which notice shall specify the length of the initial Interest Period therefor), provided that no CBFR Loan under the Revolving Facility may be converted into
a Eurodollar Loan when any Default or Event of Default has occurred and is continuing and the Administrative Agent or the Required Facility Lenders in respect of the Revolving Facility have determined in its or their sole discretion not to permit
such conversions. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. 

(b) Any Eurodollar Loan under the Revolving Facility may be continued as such upon the expiration of the then current Interest Period
with respect thereto by the Borrowers causing the Borrower Representative to give irrevocable notice to the Administrative Agent, pursuant to a Notice of Conversion/Continuation in accordance with the applicable provisions of the term “Interest
Period” set forth in Section 1.01, of the length of the next Interest Period to be applicable to such Loans, provided that no Eurodollar Loan under the Revolving Facility may be continued as such when any Default or Event of Default
has occurred and is continuing, and the Administrative Agent or the Required Facility Lenders in respect of the Revolving Facility have determined in its or their sole discretion not to permit such continuations, and provided, further, that
if the Borrower Representative shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso such Loans shall be automatically converted to CBFR Loans on the
last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. 
 Section 2.11. Limitations on Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions and continuations of Eurodollar Loans under the
Revolving Facility hereunder and all selections of Interest Periods hereunder with respect to the Revolving Facility shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate
principal amount of the Eurodollar Loans comprising each Eurodollar Tranche under the Revolving Facility shall be equal to $1,000,000 or a whole multiple of $500,000 in excess thereof and (b) no more than three (3) Eurodollar Tranches
shall be outstanding at any one time. 

  
 33 

 Section 2.12. Interest Rates and Payment Dates. 

(a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to
the Adjusted LIBO Rate determined for such day plus the Applicable Margin. 
 (b) Each CBFR Loan shall bear interest at a rate
per annum equal to the CBFR Floating Rate plus the Applicable Margin. 
 (c)   (i) If any amount of principal of any
Loan is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the
Default Rate to the fullest extent permitted by applicable Requirements of Law. 
 (ii) If any amount (other
than principal of any Loan Obligation) payable by the Borrowers under any Loan Document is not paid when due (after giving effect to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, then upon the request of
the Required Lenders such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Requirements of Law. 

(iii) Upon the request of the Required Lenders, while any Event of Default exists (or automatically while an Event of
Default exists under paragraph (f) in Section 7.01), the Borrowers shall pay interest on the principal amount of all outstanding Obligations from and after the date of the occurrence of such Event of Default at a fluctuating interest rate
per annum at all times equal to the Default Rate to the fullest extent permitted by applicable law. 
 (iv)
Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand. 

(d) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as
may be specified herein. 
 (e) Interest hereunder shall be due and payable in accordance with the terms hereof before and after
judgment, and before and after the commencement of any proceeding by or against any Borrower under any bankruptcy, insolvency, reorganization or similar law. 
 Section 2.13. Computation of Interest and Fees. 
 (a) Interest and
fees payable pursuant hereto shall be calculated on the basis of a 360-day year for the actual days elapsed. Any change in the interest rate on a Loan resulting from a change in the CBFR Floating Rate or the Statutory Reserve Rate shall become
effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower Representative and the relevant Lenders of the effective date and the amount of each
such change in interest rate. 

  
 34 

 (b) Each determination of an interest rate by the Administrative Agent pursuant to any
provision of this Agreement shall be conclusive and binding on the Borrowers and the Lenders in the absence of manifest error. 

Section 2.14. Inability to Determine Interest Rate. If prior to the first day of any Interest Period: 

(a) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrowers absent manifest
error) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate for such Interest Period, or 

(b) the Administrative Agent shall have received notice from the Required Facility Lenders in respect of the relevant Facility that the
Adjusted LIBO Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest
Period, 
 the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower Representative and the relevant Lenders as
soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans under the relevant Facility requested to be made on the first day of such Interest Period shall be made as CBFR Loans, (y) any Loans under the relevant
Facility that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as CBFR Loans and (z) any outstanding Eurodollar Loans under the relevant Facility shall be converted, on the last day of
the then current Interest Period, to CBFR Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans under the relevant Facility shall be made or continued as such, nor shall the Borrowers have the right to
convert Loans under the relevant Facility to Eurodollar Loans. 
 Section 2.15. Pro Rata Treatment and Payments.

 (a) Each borrowing by the Borrowers from the Lenders hereunder, each payment by the Borrowers on account of any commitment
fee and any reduction of the Commitments of the Lenders with respect to a particular Facility shall be made pro rata according to the Applicable Percentages, as the case may be, of the Lenders under such Facility. 

(b) Each payment (including each prepayment) by the Borrowers on account of principal of and interest on the Term Loans shall be made
pro rata according to the respective outstanding principal amounts of the Term Loans then held by the Term Lenders. The amount of each principal prepayment of the Term Loans shall be applied to reduce the remaining installments of the Term
Loans in inverse order of maturity. Amounts prepaid or repaid on account of the Term Loans may not be reborrowed. 
 (c) Each
payment (including each prepayment) by the Borrowers on account of principal of and interest on the Revolving Facility shall be made pro rata according to the respective outstanding principal amounts of the Revolving Loans then held by the
Revolving Lenders. 

  
 35 

 (d) All payments (including prepayments) to be made by the Borrowers hereunder, whether on
account of principal, interest, fees or otherwise, shall be made without any condition or deduction for any counterclaim, defense, recoupment or setoff and shall be made prior to 1:00 P.M., Dallas, Texas time, on the due date thereof to the
Administrative Agent, for the account of the Lenders, at the Funding Office, in Dollars and in immediately available funds. The Administrative Agent shall distribute to each Lender its Applicable Percentage in respect of the relevant Facility (or
other applicable share as provided herein) of each such payment promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such
payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the
result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the
preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension. 
 (e) Unless the
Administrative Agent shall have received notice from a Lender prior to the proposed date of any borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such borrowing, the Administrative Agent may
assume that such Lender has made such share available on such date in accordance with Section 2.02 or 2.05, as applicable, and may, in reliance upon such assumption, make available to the Borrower Representative a corresponding amount. In such
event, if a Lender has not in fact made such amount available to the Administrative Agent, then the applicable Lender and the Borrowers severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest
thereon, for each day from and including the date such amount is made available to the Borrower Representative to but excluding the date of payment to the Administrative Agent, at (i) in the case of a payment to be made by such Lender, the
greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (ii) in the case of a payment to be made by the Borrowers, the interest rate
applicable to CBFR Loans. If the Borrowers and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower Representative the amount of such
interest paid by the Borrowers for such period. If such Lender pays its share of the applicable borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such borrowing. Any payment by the
Borrowers shall be without prejudice to any claim the Borrowers may have against a Lender that shall have failed to make such payment to the Administrative Agent. 
 (f) Unless the Administrative Agent shall have received notice from the Borrower Representative prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders
hereunder that the Borrowers will not make such payment, the Administrative Agent may assume that the Borrowers have made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the
amount due. In such event, if the Borrowers have not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender, with interest thereon, for
each day from and including the 

  
 36 

 
date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank compensation. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against the Borrowers. 

(g) Whenever any payment received by the Administrative Agent under this Agreement or any of the other Loan Documents is insufficient to
pay in full all amounts due and payable to the Administrative Agent and the Lenders under or in respect of this Agreement and the other Loan Documents on any date, the Administrative Agent may, but shall not be obligated to, distribute such payment
in the order of priority set forth in Section 7.03. If the Administrative Agent receives funds for application to the Obligations of the Borrowers under or in respect of the Loan Documents under circumstances for which the Loan Documents do not
specify the Loans or the Facility, or the manner in which such funds are to be applied, the Administrative Agent may, but shall not be obligated to, distribute such funds in the order of priority set forth in Section 7.03. 

(h) The Borrowers hereby authorize each Lender and each Lender’s Affiliates, if and to the extent any payment owed to such Lender is
not made when due hereunder or any other Loan Document, to charge from time to time, to the fullest extent permitted by applicable law, against any or all of the Borrowers’ accounts with such Lender or such Affiliate any amount so due.

 The obligations of the Lenders hereunder to make Term Loans and Revolving Loans are several and not joint.
The failure of any Lender to make any Loan or to make any payment under Section 9.05(c) on any date required hereunder, shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible
for the failure of any other Lender to make its Loan or to make its payment under Section 9.05(c). 
 (j) Nothing herein
shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain funds for any Loan in any particular place or manner.

 Section 2.16. Illegality. Notwithstanding any other provision herein, if the adoption of or any change in any
Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such Lender hereunder to make Eurodollar
Loans, continue Eurodollar Loans as such and convert CBFR Loans to Eurodollar Loans shall forthwith be cancelled and (b) such Lender’s Loans then outstanding as Eurodollar Loans, if any, shall be converted automatically to CBFR Loans on
the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current
Interest Period with respect thereto, the Borrowers shall pay to such Lender such amounts, if any, as may be required pursuant to Section 2.20. 

  
 37 

 Section 2.17. Increased Costs. 

(a) Increased Costs Generally. If any Change in Law shall: 

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar
requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the Adjusted LIBO Rate); 

(ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses
(b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

 (iii) impose on any Lender or the London interbank market any other condition, cost or expense (other than
Taxes) affecting this Agreement or Loans made by such Lender or participation therein; 
 and the result of any of the foregoing shall be to
increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Loan or of maintaining its obligation to make any such Loan, or to reduce the amount of any sum received or receivable by such Lender or
other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or other Recipient, the Borrowers will pay to such Lender, or other Recipient, as the case may be, such additional amount or amounts as
will compensate such Lender or other Recipient, as the case may be, for such additional costs incurred or reduction suffered. 

(b) Capital Requirements. If any Lender determines that any Change in Law affecting such Lender or any lending office of such
Lender or such Lender’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if
any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by such Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into
consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy), then from time to time the Borrowers will pay to such Lender such additional amount or amounts as will compensate
such Lender or such Lender’s holding company for any such reduction suffered. 
 (c) Certificates for Reimbursement.
A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section and delivered to the Borrower
Representative, shall be conclusive absent manifest error. The Borrower Representative shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 

(d) Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not
constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrowers shall not be required to compensate a 

  
 38 

 
Lender pursuant to this Section for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender notifies the Borrower Representative of the Change
in Law giving rise to such increased costs or reductions, and of such Lender’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 nine-month
period referred to above shall be extended to include the period of retroactive effect thereof). 
 (e) Survival. The
obligations of the Borrowers pursuant to this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder. 
 Section 2.18. Taxes. 
 (a) Payments Free of Taxes. Any
and all payments by or on account of any obligation of any Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith
discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall
timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Borrower shall be increased as necessary so that
after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such
deduction or withholding been made. 
 (b) Payment of Other Taxes by the Borrowers. The Borrowers shall timely pay
to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes. 
 (c) Indemnification by the Borrowers. The Borrowers shall jointly and severally indemnify each Recipient, within 10 days after demand therefor, for the full amount of any Indemnified Taxes
(including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising
therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower
Representative by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. 

(d) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 10 days after
demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the
Borrowers to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.06(d) relating to the maintenance of a Participant Register and (iii) any

  
 39 

 
Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom
or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent
shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to
the Lender from any other source against any amount due to the Administrative Agent under this paragraph (d). 
 (e)
Evidence of Payments. As soon as practicable after any payment of Taxes by any Borrower to a Governmental Authority pursuant to this Section 2.18, such Borrower shall deliver to the Administrative Agent the original or a certified copy
of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 

(f) Status of Lenders. 
 (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower Representative and the
Administrative Agent, at the time or times reasonably requested by the Borrower Representative or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower Representative or the Administrative
Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower Representative or the Administrative Agent, shall deliver such other
documentation prescribed by applicable law or reasonably requested by the Borrower Representative or the Administrative Agent as will enable the Borrower Representative or the Administrative Agent to determine whether or not such Lender is subject
to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in
Section 2.18(f) (ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would
materially prejudice the legal or commercial position of such Lender. 
 (ii) Without limiting the generality of the foregoing:

 (A) any Lender that is a U.S. Person shall deliver to the Borrower Representative and the Administrative Agent
on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower Representative or the Administrative Agent), executed originals of IRS Form W-9
certifying that such Lender is exempt from U.S. federal backup withholding Tax; 
 (B) any Foreign Lender shall,
to the extent it is legally entitled to do so, deliver to the Borrower Representative and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign 

  
 40 

 
Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower Representative or the Administrative Agent), whichever of the following
is applicable: 
 (1) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the
United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest”
article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits”
or “other income” article of such tax treaty; 
 (2) executed originals of IRS Form W-8ECI;

 (3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under
Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit I-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent
shareholder” of any Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”)
and (y) executed originals of IRS Form W-8BEN; or 
 (4) to the extent a Foreign Lender is not the
beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit 1-2 or Exhibit 1-3, IRS Form W-9, and/or other
certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such
Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit 1-4 on behalf of each such direct and indirect partner; 
 (C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower Representative and the Administrative Agent (in such number of copies as shall be requested by the
recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower Representative or the Administrative Agent), executed originals of
any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the
Borrower Representative or the Administrative Agent to determine the withholding or deduction required to be made; and 
 (D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements
of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower Representative and the Administrative Agent at the time or times prescribed by law

  
 41 

 
and at such time or times reasonably requested by the Borrower Representative or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by
Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower Representative and the Administrative Agent to comply with their
obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA”
shall include any amendments made to FATCA after the date of this Agreement. 
 Each Lender agrees that if any form or
certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower Representative and the Administrative Agent in writing of its legal inability
to do so. 
 (g) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good
faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.18 (including by the payment of additional amounts pursuant to this Section 2.18), it shall pay to the indemnifying party an
amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without
interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to
this paragraph (g) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything
to the contrary in this paragraph (g), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (g) the payment of which would place the indemnified party in a less favorable net
after-Tax position than the indemnified party would have been in if the Tax subject to the indemnification and giving rise to such refund had not been deducted, withheld or otherwise imputed or if indemnification payments or additional amounts
giving rise to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying
party or any other Person. 
 (h) For purposes of this Section 2.18, the term “applicable law” includes FATCA.

 (i) The agreements in this Section shall survive the termination of this Agreement and the payment of the Loans and all other
amounts payable hereunder. 
 Section 2.19. Mitigation Obligations.; Replacement of Lenders: Designation of a
Different Lending Office. (a) If any Lender requests compensation under Section 2.17, or requires any Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any
Lender pursuant to Section 2.18, then such Lender shall (at the request of the Borrower Representative) use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and

  
 42 

 
obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable
pursuant to Section 2.17 or 2.18, as the case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrowers hereby agree to pay
all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 
 (b)
Replacement of Lenders. If any Lender requests compensation under Section 2.17, or if any Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender
pursuant to Section 2.18 and, in each case, such Lender has declined or is unable to designate a different lending office in accordance with Section 2.19(a), or if any Lender is a Defaulting Lender or a Non-Consenting Lender, then the
Borrower Representative may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and
consents required by, Section 9.06), all of its interests, rights (other than its existing rights to payments pursuant to Section 2.17 or Section 2.18) and obligations under this Agreement and the related Loan Documents to an Eligible
Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that: 
 (i) the Borrowers shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 9.06; 

(ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued
interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 2.20) from the assignee (to the extent of such outstanding principal and accrued interest and
fees) or the Borrowers (in the case of all other amounts); 
 (iii) in the case of any such assignment resulting
from a claim for compensation under Section 2.17 or payments required to be made pursuant to Section 2.18, such assignment will result in a reduction in such compensation or payments thereafter; 

(iv) such assignment does not conflict with applicable law; and 

(v) in the case of any assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable assignee shall
have consented to the applicable amendment, waiver or consent. 
 A Lender shall not be required to make any such assignment or delegation if,
prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower Representative to require such assignment and delegation cease to apply. 

Section 2.20. Indemnity. The Borrowers agree to indemnify each Lender and to hold each Lender harmless from any loss or
expense that such Lender may sustain or incur as a consequence of (a) default by any of the Borrowers in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower Representative has given a notice requesting
the same in accordance with the provisions of this Agreement, (b) default by any of the 

  
 43 

 
Borrowers in making any prepayment of or conversion from Eurodollar Loans after the Borrower Representative has given a notice thereof in accordance with the provisions of this Agreement,
(c) the making of a prepayment of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto, or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable
thereto as a result of a request by the Borrower Representative pursuant to Section 2.19(b). Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so
prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or
continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over
(ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. A
certificate as to any amounts payable pursuant to this Section submitted to the Borrower Representative by any Lender shall be conclusive in the absence of manifest error. The Borrowers shall pay such Lender the amount shown as due on any such
certificate within ten (10) days after receipt thereof. This covenant shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder. 

Section 2.21. Use of Proceeds. The proceeds of the Term Loans shall be available (and the Borrowers agree that they will use
such proceeds) solely to repay in full the Existing Indebtedness and related transaction fees and expenses. The proceeds of the Revolving Loans shall be available (and the Borrowers agree that they will use such proceeds) solely to finance working
capital needs of the Borrowers in the ordinary course of business, including making payments due on the Closing Date in connection with the Transactions. 
 Section 2.22. Evidence of Debt. 
 (a) Each Lender shall maintain in
accordance with its usual practice an account or accounts evidencing indebtedness of the Borrowers to such Lender resulting from each Loan of such Lender from time to time, including the amounts of principal and interest payable and paid to such
Lender from time to time under this Agreement. 
 (b) The Administrative Agent shall maintain the Register pursuant to
Section 9.06(c), and a subaccount therein for each Lender, in which shall be recorded (i) the amount of each Loan, made hereunder, the Type thereof and each Interest Period applicable thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable to the Lenders hereunder, and (iii) both the amount of any sum received by the Administrative Agent hereunder from the Borrowers and each Lender’s share thereof. 

(c) The entries made in the Register and the accounts of each Lender maintained pursuant hereto shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the obligations of the Borrowers therein recorded, provided, however, that the failure of any Lender or the Administrative Agent to maintain the Register or any
such account, or any error therein, shall not in any manner affect the obligation of the Borrowers to repay (with applicable interest) the Loans made to the Borrowers in accordance with the terms of this Agreement. 

  
 44 

 (d) The Borrowers agree that, upon the request to the Administrative Agent by any applicable
Lender, the Borrowers will execute and deliver to such Lender, as appropriate, (i) a promissory note of the Borrowers evidencing the Revolving Loans of such Lender, substantially in the form of Exhibit C-1 with appropriate insertions as
to date and principal amount (a “Revolving Note”), (ii) a promissory note of the Borrowers evidencing the Tranche A Term Loan of such Lender, substantially in the form of Exhibit C-2 with appropriate insertions as to
date and principal amount (a “Tranche A Term Note”), (iii) a promissory note of the Borrowers evidencing the Tranche B Term Loan of such Lender, substantially in the form of Exhibit C-3 with appropriate insertions as to
date and principal amount (a “Tranche B Term Note”), and (iv) a promissory note of the Borrowers evidencing the Tranche C Term Loan of such Lender, substantially in the form of Exhibit C-4 with appropriate insertions as
to date and principal amount (a “Tranche C Term Note”). Each Lender is hereby authorized to record the Borrowing Date, the amount of each relevant Loan and the date and amount of each payment or prepayment of principal thereof, on
the schedule annexed to and constituting a part of the Note evidencing such Loan and any such recordation shall constitute prima facie evidence of the accuracy of the information so recorded, provided that the failure by a Lender to make any
such recordation (or any error therein) shall not affect any of the obligations of the Borrowers under such Note or this Agreement. 
 Section 2.23. Borrower Representative. Each Borrower hereby irrevocably appoints Holdings as the borrowing agent and attorney-in-fact for all Borrowers (the “Borrower
Representative”) which appointment shall remain in full force and effect unless and until Administrative Agent shall have received prior written notice signed by each Borrower that such appointment has been revoked and that another Borrower
has been appointed as to the Borrower Representative. Each Borrower hereby irrevocably appoints and authorizes the Borrower Representative (a) to provide the Administrative Agent with all requests, notices, instructions and certificates with
respect to the Loans obtained and all other notices and instructions under this Agreement and (b) to take such action as the Borrower Representative deems appropriate on its behalf with respect to the Loans and to exercise such other powers and
take such actions as are reasonably incidental thereto to carry out the purposes of this Agreement. It is understood that the handling of the Loans and Collateral of the Borrowers in a combined fashion, as more fully set forth herein, is done solely
as an accommodation to the Borrowers in order to utilize the collective borrowing powers of Borrowers in the most efficient and economical manner and at their request, and that the Administrative Agent and the Lenders shall not incur liability to
any Borrower as a result hereof Each Borrower will derive benefit, directly or indirectly, from the handling of the Loans and the Collateral in a combined fashion since the successful operation of each Borrower is dependent on the continued
successful performance of the integrated group. TO INDUCE THE ADMINISTRATIVE AGENT AND THE LENDERS TO DO SO, AND IN CONSIDERATION THEREOF, THE BORROWERS HEREBY JOINTLY AND SEVERALLY AGREE TO INDEMNIFY EACH INDEMNITEE AND HOLD EACH INDEMNITEE
HARMLESS AGAINST ANY AND ALL LIABILITY, EXPENSE, LOSS OR CLAIM OF DAMAGE OR INJURY, MADE AGAINST ANY INDEMNITEE BY ANY BORROWER OR BY ANY THIRD PARTY WHOMSOEVER, ARISING FROM OR INCURRED BY REASON OF (A) THE ADMINISTRATION OF THE LOANS AND

  
 45 

 
COLLATERAL, (B) THE ADMINISTRATIVE AGENT OR ANY LENDER RELYING ON ANY NOTICES, INSTRUCTIONS, CERTIFICATES OR REQUESTS OF THE BORROWER REPRESENTATIVE, OR (C) ANY OTHER ACTION TAKEN BY
THE ADMINISTRATIVE AGENT AND THE LENDERS HEREUNDER OR UNDER THE OTHER LOAN DOCUMENTS. THE ADMINISTRATIVE AGENT AND THE LENDERS AND THEIR RELATED PARTIES SHALL NOT BE LIABLE TO THE BORROWERS FOR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY THE BORROWER
REPRESENTATIVE PURSUANT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT. 
 Section 2.24. Joint and Several Liability
of Borrowers. 
 (a) Each Borrower is accepting joint and several liability hereunder and under the other Loan Documents in
consideration of the financial accommodations to be provided by Administrative Agent and the Lenders under this Agreement, for the mutual benefit, directly and indirectly, of each Borrower and in consideration of the undertakings of the other
Borrowers to accept joint and several liability for the payment and performance of the Obligations. 
 (b) Each Borrower,
jointly and severally, hereby irrevocably and unconditionally accepts, not merely as a surety but also as a primary obligor, joint and several liability with the other Borrowers, with respect to the payment and performance of all of the Obligations,
it being the intention of the parties hereto that all of the Obligations shall be the joint and several obligations of the Borrowers. 
 (c) If and to the extent that any of the Borrowers shall fail to make any payment with respect to any of the Obligations as and when due or to perform any of the Obligations in accordance with the terms
thereof, then in each such event the other Borrowers will make such payment with respect to, or perform, such Obligation. 
 (d)
The Obligations of each Borrower constitute the absolute and unconditional, full recourse Obligations of each Borrower enforceable against each such Borrower, irrespective of the validity, regularity or enforceability of this Agreement or any other
circumstances whatsoever. 
 (e) Each Borrower hereby waives notice of acceptance of its joint and several liability, notice of
any Loans made or issued under or pursuant to this Agreement, notice of the occurrence of any Default, Event of Default, or of any demand for any payment under this Agreement, notice of any action at any time taken or omitted by the Administrative
Agent or any Lender under or in respect of any of the Obligations, any requirement of diligence or to mitigate damages and, generally, to the extent permitted by applicable Requirements of Law, all demands, notices and other formalities of every
kind in connection with this Agreement (except as otherwise expressly provided in this Agreement). Each Borrower hereby consents to, and waives notice of, any extension or postponement of the time for the payment of any of the Obligations, the
acceptance of any payment of any of the Obligations, the acceptance of any partial payment thereon, any waiver, consent or other action or acquiescence by the Administrative Agent or any Lender at any time or times in respect of any default by any
Borrower in the performance or satisfaction of any term, covenant, condition or provision of this 

  
 46 

 
Agreement or any other Loan Document, any and all other indulgences whatsoever by the Administrative Agent or any Lender in respect of any of the Obligations, and the taking, addition,
substitution or release, in whole or in part, at any time or times, of any security for any of the Obligations or the addition, substitution or release, in whole or in part, of any Borrower. Without limiting the generality of the foregoing, each
Borrower consents to any other action or delay in acting or failure to act on the part of the Administrative Agent or any Lender with respect to the failure by any Borrower to comply with any of its respective Obligations, including, without
limitation, any failure strictly or diligently to assert any right or to pursue any remedy or to comply fully with applicable Requirements of Law, which might, but for the provisions of this Section 2.24, afford grounds for terminating,
discharging or relieving any Borrower, in whole or in part, from any of its Obligations, it being the intention of each Borrower that the Obligations of each Borrower shall not be discharged except by the payment in full in cash of the Obligations
and the termination or expiration of the Commitments. The Obligations of each Borrower shall not be diminished or rendered unenforceable by any winding up, reorganization, arrangement, liquidation, reconstruction or similar proceeding with respect
to any Borrower. 
 Each Borrower represents and warrants to Administrative Agent and the Lenders that such
Borrower is currently informed of the financial condition of the Borrowers and of all other circumstances which a diligent inquiry would reveal and which bear upon the risk of nonpayment of the Obligations. Each Borrower further represents and
warrants to Administrative Agent and the Lenders that such Borrower has read and understands the terms and conditions of the Loan Documents. Each Borrower hereby agrees that it will continue to keep informed as to the financial condition of each of
the Borrowers, the financial condition of each guarantor, and of all other circumstances that bear upon the risk of nonpayment or nonperformance of the Obligations. 
 (g) The provisions of this Section 2.24 are for the benefit of the Administrative Agent, the Lenders and their respective successors and assigns, and may be enforced by it or them from time to time
against any or all of the Borrowers and without requirement on the part of the Administrative Agent, any Lender or any successor or assign first to marshal any of its or their claims or to exercise any of its or their rights against any of the other
Borrowers or to exhaust any remedies available to it or them against any of the other Borrowers or to resort to any other source or means of obtaining payment of any of the Obligations hereunder or to elect any other remedy. If at any time, any
payment, or any part thereof, made in respect of any of the Obligations, is rescinded or must otherwise be restored or returned by the Administrative Agent or any Lender upon the insolvency, bankruptcy or reorganization of any Borrower or otherwise,
the Obligations of the Borrowers with respect to that payment will forthwith be reinstated in effect, as though such payment had not been made. 
 (h) Each Borrower hereby agrees that it will not enforce any of its rights of contribution, indemnification, reimbursement or subrogation against any of the other Borrowers with respect to any liability
incurred by it hereunder or under any of the other Loan Documents, any payments made by it to the Administrative Agent or the Lenders with respect to any of the Obligations or any collateral security therefor until such time as all of the
Obligations have been paid in full in cash and the Commitments have terminated. Any claim that any Borrower may have against any other Borrower with respect to any payments to the Administrative Agent or 

  
 47 

 
any Lender hereunder or under any other Loan Document are hereby expressly made subordinate and junior in right of payment, without limitation as to any increases in the Obligations arising
hereunder or thereunder, to the prior payment in full in cash of the Obligations and, in the event of any proceeding under any Debtor Relieve Law under the laws of any jurisdiction relating to any Borrower, its debts or its assets, whether voluntary
or involuntary, all of the Obligations shall be paid in full in cash before any payment or distribution of any character, whether in cash, securities or other property, shall be made to any other Borrower therefor. 

Section 2.25. Defaulting Lenders. 
 (a) Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer
a Defaulting Lender, to the extent permitted by applicable law: 
 (i) Waivers and Amendments. Such
Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Required Lenders. 

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the
Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VII or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 9.07 shall
be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, as the Borrower Representative
may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent;
third, if so determined by the Administrative Agent and the Borrower Representative, to be held in a deposit account and released pro rata in order to satisfy such Defaulting Lender’s potential future funding obligations with respect to
Loans under this Agreement; fourth, to the payment of any amounts owing to the Lenders, as a result of any judgment of a court of competent jurisdiction obtained by any Lender against such Defaulting Lender as a result of such Defaulting
Lender’s breach of its obligations under this Agreement; fifth, so long as no Default or Event of Default exists, to the payment of any amounts owing to any Borrower as a result of any judgment of a court of competent jurisdiction obtained by
the such Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and sixth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction;
provided that if (x) such payment is a payment of the principal amount of any Loans in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made at a time when the conditions
set forth in Section 3.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of such Defaulting Lender until such
time as all Loans are held by the Lenders pro rata in accordance with the Commitments under the applicable Facility. 
 (iii) Certain Fees. No Defaulting Lender shall be entitled to receive any Commitment Fee for any period during which that Lender is a Defaulting Lender (and the Borrowers shall not be required to

 (b) Defaulting Lender Cure. If the Borrower Representative and the Administrative
Agent agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may
include arrangements with respect to any cash collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be
necessary to cause the Loans to be held pro rata by the Lenders in accordance with the Commitments under the applicable Facility, whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made
retroactively with respect to fees accrued or payments made by or on behalf of the Borrowers while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no
change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

itself and all other Borrowers, and each Borrower hereby represents and warrants to the Administrative Agent and each Lender on behalf of itself that (and after the Closing Date when the following representations and warranties are made or deemed

(ii) the Loans to be made on the Closing Date and the use of proceeds thereof and (iii) the payment of fees and

fairly on a pro forma basis the estimated financial position of Borrowers as at August 31, 2012, assuming that the events specified in the preceding sentence had actually occurred at such date. 

(b) The audited consolidated balance sheet of Holdings as at December 31, 2011, and the related consolidated statements of income
and of cash flows for the Fiscal Year ended on such dates, reported on by and accompanied by an unqualified report from Grant Thornton LLP, present fairly the consolidated financial condition of the Holdings as at such date, and the consolidated
results of its operations and its consolidated cash flows for the Fiscal Year then ended. The unaudited consolidated balance sheet of Holdings as at June 30, 2012, and the related unaudited consolidated statements of income and cash flows for
the 6-month period ended on such date, present fairly the consolidated financial condition of Holdings as at such date, and the consolidated results of its operations and its consolidated cash flows for the 6-month period then ended (subject to
normal year-end audit adjustments and the absence of footnotes). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved
(except as approved by the aforementioned firm of accountants and disclosed therein). None of the Borrowers has any material Guarantee Obligations, contingent liabilities, liabilities for Taxes or any long-term leases or unusual forward or long-term
commitments, including any interest rate or foreign currency swap or exchange transaction or other obligation in respect of derivatives, that are not reflected in the most recent financial statements referred to in this paragraph or in the Schedules

 Section 4.04. Corporate Power; Authorization; Enforceable Obligations. Each Borrower has all requisite corporate
or other applicable entity power and authority to make, deliver and perform the Loan Documents to which it is a party and, in the case of the Borrowers, to obtain extensions of credit hereunder. Each Borrower has taken all necessary organizational

in respect of, any Governmental Authority or any other Person is required in connection with the Transactions and the extensions of credit hereunder or with the execution, delivery, performance, validity or enforceability of this Agreement or any of
the Loan Documents, except (i) consents, authorizations, filings and notices described in Schedule 4.04, which consents, authorizations, filings and notices have been obtained or made and are in full force and effect, and (ii) the
filings referred to in Section 4.18. Each Loan Document has been duly executed and delivered on behalf of each Borrower that is a party thereto. This Agreement constitutes, and each other Loan Document upon execution will constitute, a legal,
valid and binding obligation of each Borrower party thereto, enforceable against each such Borrower in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar
laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law). 
 Section 4.05. No Legal Bar. The execution, delivery and performance of this Agreement and the other Loan Documents, the borrowings hereunder and the use of the proceeds thereof will not
violate any Requirement of Law or any Contractual Obligation of any Borrower and will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such
Contractual Obligation (other than the Liens created by the Security Documents). No Requirement of Law or Contractual Obligation applicable to any of the Borrowers could reasonably be expected to have a Material Adverse Effect. The Transactions
comply with all applicable Requirements of Law. 
 Section 4.06. Litigation. No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of any of the Borrowers, threatened by or against any Borrower or against any of their respective properties or revenues (a) with respect to the

 Section 4.09. Intellectual Property. Each Borrower owns, or is licensed to use,
all Intellectual Property necessary for the conduct of its business as currently conducted. No material claim has been asserted and is pending by any Person challenging or questioning the use of any Intellectual Property or the validity or
effectiveness of any Intellectual Property, nor does any Borrower know of any valid basis for any such claim. The use of Intellectual Property by each Borrower does not infringe on the rights of any Person in any material respect. 

  
 54 

 Section 4.10. Taxes. Each Borrower has filed or caused to be filed all Federal,
state, and other material Tax returns that are required to be filed and has paid all Taxes shown to be due and payable on said returns or on any material assessments made against it or any of its property and all other material Taxes, fees or other
charges imposed on it or any of its property by any Governmental Authority (other than any the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with
GAAP have been provided on the books of the relevant Borrower); no Tax Lien has been filed, and, to the knowledge of each Borrower, no claim is being asserted, with respect to any such Tax, fee or other charge. No Borrower is a party to any Tax
sharing or Tax allocation agreement. No foreign, federal, state, or local Tax audits or administrative or judicial Tax proceedings are pending or being conducted with respect to any Borrower. No Borrower has waived any statute of limitations in
respect of Taxes or agreed to any extension of time with respect to a Tax assessment of deficiency.

No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect. The

amounts, exceed the fair market value of the assets of such Plan, and the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Accounting Standards Codification No. 715)

review, or other action pending or, to the knowledge of any Borrower, threatened, which could result in a revocation, suspension, termination, probation, material restriction, material limitation, or non-renewal of any Program participation
agreement or result in any Borrower’s exclusion from any Program, except as could not reasonably be expected to have a Material Adverse Effect. 
 (c) None of the Borrowers or any of their respective officers and directors has been or is currently excluded from participation in government health care programs pursuant to 42 U.S.C. § 1320a-7

 (a)

(b) declare the unpaid principal amount of all outstanding Loans, all interest accrued and unpaid thereon, and all other amounts owing or
payable hereunder or under any other Loan Document to be immediately due and payable, without presentment, demand, protest, notice of acceleration, notice of intent to accelerate or other notice of any kind, all of which are hereby expressly waived
by the Borrowers; and 
 (c) exercise on behalf of itself and the Lenders all rights and remedies available to it and the

Representative or as otherwise required by applicable law. 
 The order of priority set forth in the clauses above may at any time and from time
to time be changed by the agreement of the Administrative Agent and the Lenders as required pursuant to Section 9.01 without necessity of notice to or consent of or approval by any Borrower or any other Person that is not a Lender. 

ARTICLE VIII 
 AGENCY 
 Section 8.01. Appointment and Authority. Each of the
Lenders hereby irrevocably appoints JPMorgan to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are
delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent and the Lenders,
and none of the Borrowers has rights as a third-party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to
the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or
reflect only an administrative relationship between contracting parties. 
 Section 8.02. Rights as a Lender. The
Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and the term “Lender” or
“Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits
from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for, and generally engage in any kind of business with, any Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the
Administrative Agent hereunder and without any duty to account therefor to the Lenders. 
 Section 8.03. Exculpatory
Provisions. 
 (a) The Administrative Agent shall not have any duties or obligations except those expressly set forth herein
and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent: 

  
 75 

 (i) shall not be subject to any fiduciary or other implied duties,
regardless of whether a Default has occurred and is continuing; 
 (ii) shall not have any duty to take any
discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the
Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that the Administrative Agent shall not be required to take any action that, in its
opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that may be in violation of the automatic stay under
any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and 
 (iii) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to any
Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity. 
 (b) The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the
Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 9.01 and 7.02), or (ii) in the absence of its own gross negligence or willful misconduct as
determined by a court of competent jurisdiction by final and nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent
in writing by the Borrower Representative or a Lender. 
 (c) The Administrative Agent shall not be responsible for or have any
duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or
thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity,
enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or the creation, perfection or priority of any Lien created pursuant to the Security Documents, or (v) the
satisfaction of any condition set forth in Article III or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. 

Section 8.04. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur
any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine
and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur
any liability for 

  
 76 

 
relying thereon. In determining compliance with any condition hereunder to the making of a Loan, the Administrative Agent may presume that such condition is satisfactory to such Lender unless the
Administrative Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. The Administrative Agent may consult with legal counsel (who may be counsel for any Borrower), independent accountants and other
experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 
 Section 8.05. Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through
any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The
exculpatory provisions of this Article shall apply to any such sub agent and to the Related Parties of the Administrative Agent and any such sub agent, and shall apply to their respective activities in connection with the syndication of the
Facilities as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and
nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub agents. 
 Section 8.06. Resignation of Administrative Agent. 
 (a) The
Administrative Agent may at any time give notice of its resignation to the Lenders and the Borrower Representative. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower
Representative, to appoint a successor, which shall be a bank with an office in Dallas, Texas, or an Affiliate of any such bank with an office in Dallas, Texas. If no such successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring
Administrative Agent may (but shall not be obligated to), on behalf of the Lenders appoint a successor Administrative Agent meeting the qualifications set forth above. Whether or not a successor has been appointed, such resignation shall become
effective in accordance with such notice on the Resignation Effective Date. 
 (b) If the Person serving as Administrative Agent
is a Defaulting Lender pursuant to clause (d) of the definition thereof, the Required Lenders may, to the extent permitted by applicable law, by notice in writing to the Borrower Representative and such Person remove such Person as
Administrative Agent and, in consultation with the Borrower Representative, appoint a successor. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days (or such earlier day
as shall be agreed by the Required Lenders) (the “Removal Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date. 

  
 77 

 (c) With effect from the Resignation Effective Date or the Removal Effective Date (as
applicable) (1) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent
on behalf of the Lenders under any of the Loan Documents, the retiring or removed Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (2) except for any
indemnity payments owed to the retiring or removed Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such
time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all
of the rights, powers, privileges and duties of the retiring or removed Administrative Agent (other than any rights to indemnity payments owed to the retiring or removed Administrative Agent), and the retiring or removed Administrative Agent shall
be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by the Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed
between the Borrowers and such successor. After the retiring or removed Administrative Agent’s resignation or removal hereunder and under the other Loan Documents, the provisions of this Article and Section 9.05 shall continue in effect
for the benefit of such retiring or removed Administrative Agent, its subagents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring or removed Administrative Agent was acting
as Administrative Agent. 
 Section 8.07. Non-Reliance on Administrative Agent and Other Lenders. Each Lender
acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such 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 the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it
shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder. Each
Lender acknowledges that Condon Thornton Sladek Harrell PLLC is acting in this transaction as counsel to the Administrative Agent only. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in
connection with the Loan Documents and the matters contemplated therein. 
 Section 8.08. Administrative Agent May File
Proofs of Claim. In case of the pendency of any case, proceeding or other action of a nature under any Debtor Relief Law or any other judicial proceeding relative to any Borrower, the Administrative Agent (irrespective of whether the principal
of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrowers) shall be entitled and empowered, by intervention in such
proceeding or otherwise: 
 (a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in
respect of the Loans and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the 

  
 78 

 
Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective
agents and counsel) and all other amounts due the Lenders and the Administrative Agent under Sections 2.06 and 9.05 allowed in such judicial proceeding; and 
 (b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same; 
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the
Administrative Agent and, if the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of
the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 9.05. 
 Nothing herein contained shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or
composition affecting the Obligations or the rights of any Lender to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding. 
 Section 8.09. Collateral and Guarantee Matters. The Lenders irrevocably authorize the Administrative Agent, at its option and in its discretion: 

(a) to release any Lien on any property granted to or held by the Administrative Agent under any Loan Document (i) upon termination
of the Commitments and payment in full of all Obligations (other than contingent indemnification obligations), (ii) that is sold or otherwise Disposed of or to be sold or otherwise Disposed of as part of or in connection with any sale or other
Disposition permitted under the Loan Documents, or (iii) if approved, authorized or ratified in writing in accordance with Section 9.01; 
 (b) to release any Borrower from its guarantee under the Guarantee and Collateral Agreement if such Person ceases to be a Wholly Owned Subsidiary as a result of a transaction expressly permitted
hereunder; and 
 (c) to subordinate any Lien on any property granted to or held by the Administrative Agent under any Loan
Document to the holder of any Lien on such property that is permitted by Section 6.03(g). 
 Upon request by the
Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Borrower from its guarantee
under the Guarantee and Collateral Agreement pursuant to this Section 8.09. In each case as specified in this Section 8.09, the Administrative Agent will, at the Borrowers’ expense, execute and deliver to the applicable Borrower such
documents as such Borrower may reasonably request to evidence the release of such item of Collateral from the Liens granted under the Security Documents or to subordinate its interest in such item, or to release such Borrower from its guarantee
under the Guarantee and Collateral Agreement, in each case in accordance with the terms of the Loan Documents and this Section 8.09. 

  
 79 

 The Administrative Agent shall not be responsible for or have a duty to ascertain or inquire
into any representation or warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of the Administrative Agent’s Lien thereon, or any certificate prepared by any Borrower in connection
therewith, nor shall the Administrative Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral.

Related Parties of each of them from all losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given by or on behalf of the Borrowers. All telephonic notices to and other telephonic
communications with the Administrative Agent may be recorded by the Administrative Agent and each of the parties hereto hereby consents to such recording. 
 Section 9.03. No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of the Administrative Agent or any Lender, any right, remedy, power or privilege
hereunder or under the other Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law. 

Section 9.04. Survival. All covenants, agreements, representations and warranties made by the Borrowers, and each of them,
herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement
and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or
warranty at the time any credit is 

  
 83 

 
extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is
outstanding and unpaid and so long as the Commitments have not expired or terminated. 
 Section 9.05. Expenses;
Indemnity; Damage Waiver. 
 (a) Costs and Expenses. The Borrowers shall jointly and severally pay
(i) all reasonable out-of-pocket expenses incurred by the Administrative Agent (including the reasonable fees, charges and disbursements of counsel for the Administrative Agent) in connection with the syndication of the Facilities, the
preparation, negotiation, execution, delivery and administration of this Agreement and the other Loan Documents, or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or
thereby shall be consummated), and (ii) all out-of-pocket expenses incurred by the Administrative Agent or any Lender (including the fees, charges and disbursements of any counsel for the Administrative Agent or any Lender), in connection with
the enforcement or protection of its rights (A) in connection with this Agreement and the other Loan Documents, including its rights under this Section, or (B) in connection with the Loans made hereunder, including all such out-of-pocket
expenses incurred during any workout, restructuring or negotiations in respect of such Loans.

INDEMNIFICATION BY THE BORROWERS. THE BORROWERS SHALL JOINTLY AND SEVERALLY INDEMNIFY THE ADMINISTRATIVE AGENT (AND ANY SUB-AGENT THEREOF) AND EACH LENDER AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED
AN “INDEMNITEE”) AGAINST, AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES AND RELATED EXPENSES (INCLUDING THE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE), INCURRED BY
ANY INDEMNITEE OR ASSERTED AGAINST ANY INDEMNITEE BY ANY PERSON (INCLUDING THE BORROWERS) OTHER THAN SUCH INDEMNITEE AND ITS RELATED PARTIES ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (I) THE EXECUTION OR DELIVERY OF THIS AGREEMENT,
ANY OTHER LOAN DOCUMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY OR THEREBY, THE PERFORMANCE BY THE PARTIES HERETO OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY OR
THEREBY, (II) ANY LOAN OR THE USE OR PROPOSED USE OF THE PROCEEDS THEREFROM, (III) ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY ANY BORROWER, OR ANY ENVIRONMENTAL LIABILITY RELATED IN
ANY WAY TO ANY BORROWER, OR (IV) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY, WHETHER BROUGHT BY A THIRD PARTY OR BY ANY BORROWER, AND
REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, 

  
 84 

 
DAMAGES, LIABILITIES OR RELATED EXPENSES ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT
OF SUCH INDEMNITEE OR DISPUTES AMONG INDEMNITEES. THIS SECTION 9.05(B) SHALL NOT APPLY WITH RESPECT TO TAXES. 

(c) REIMBURSEMENT BY LENDERS. TO THE EXTENT THAT THE BORROWERS FOR ANY REASON FAIL TO PAY ANY AMOUNT REQUIRED UNDER
PARAGRAPH (A) OR (B) OF THIS SECTION TO BE PAID BY IT TO THE ADMINISTRATIVE AGENT (OR ANY SUB-AGENT THEREOF) OR ANY RELATED PARTY OF ANY OF THE FOREGOING, EACH LENDER SEVERALLY AGREES TO PAY TO THE ADMINISTRATIVE AGENT (OR ANY SUCH
SUB-AGENT) OR SUCH RELATED PARTY, AS THE CASE MAY BE, SUCH LENDER’S PRO RATA SHARE (DETERMINED AS OF THE TIME THAT THE APPLICABLE UNREIMBURSED EXPENSE OR INDEMNITY PAYMENT IS SOUGHT BASED ON EACH LENDER’S SHARE OF THE AGGREGATE EXPOSURE AT
SUCH TIME) OF SUCH UNPAID AMOUNT (INCLUDING ANY SUCH UNPAID AMOUNT IN RESPECT OF A CLAIM ASSERTED BY SUCH LENDER). THE OBLIGATIONS OF THE LENDERS UNDER THIS PARAGRAPH (C) ARE SUBJECT TO THE PROVISIONS OF SECTION 2.15(I). 

(d) WAIVER OF CONSEQUENTIAL DAMAGES, ETC. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE BORROWERS SHALL
NOT ASSERT, AND HEREBY WAIVE, 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, ANY OTHER LOAN DOCUMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY, THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, ANY LOAN OR THE USE OF THE PROCEEDS THEREOF. NO INDEMNITEE REFERRED TO IN PARAGRAPH (B) ABOVE SHALL BE

 Section 9.06. Successors and Assigns; Participations and Assignments.

 (a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns permitted hereby, except that none of the Borrowers may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the
Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of
participation in accordance with the provisions of paragraph (d) of this Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or
transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby,
Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by
reason of this Agreement. 
 (b) Assignments by Lenders. Any Lender may at any time assign to one or more
assignees all or a portion of its 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 (in each case with respect to any Facility) 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/or the Loans
at the time owing to it (in each case with respect to any Facility) or contemporaneous assignments to related Approved Funds that equal at least the amount specified in paragraph (b)(i)(B) of this Section in the aggregate 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 paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for
this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date the
Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000, in the
case of any assignment in respect of the Revolving Facility, or $1,000,000, in the case of any assignment in respect of a Term Facility, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the
Borrower Representative otherwise consents (each such consent not to be unreasonably withheld or delayed). 

(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 Loans or the Commitments assigned, provided that each assignment must be ratable among all of the Facilities. 

  
 86 

 (iii) Required Consents. No consent shall be required for any
assignment except to the extent required by paragraph (b)(i)(B) of this Section and, in addition: 
 (A) the
consent of the Borrower Representative (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 the Borrower Representative shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five
(5) Business Days after having received notice thereof and provided, further, that the Borrower Representative’s consent shall not be required during the primary syndication of the Facilities; and 

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required
for assignments in respect of (i) the Revolving Facility or any unfunded Commitments with respect to the Term Facilities 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) any Term Loans to a Person who is not a Lender, an Affiliate of a Lender or an Approved Fund. 

(iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative
Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; provided that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any
assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. 
 (v) No Assignment to Certain Persons. No such assignment shall be made to (A) any Borrower or any Affiliate or Subsidiary of any Borrower or (B) to any Defaulting Lender or any of its
Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B). 
 (vi) No Assignment to Natural Persons. No such assignment shall be made to a natural Person. 
 (vii) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in
addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be
outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower Representative and the Administrative Agent, the applicable pro rata share of
Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to
the Administrative Agent and each Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans in accordance with its Applicable Percentage. Notwithstanding the foregoing, in
the event that any assignment of rights and obligations of any 

  
 87 

 
Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a
Defaulting Lender for all purposes of this Agreement until such compliance occurs. 
 Subject to acceptance and recording thereof by the
Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest
assigned by such Assignment and Assumption, 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 Assumption, be released from its
obligations under this Agreement (and, in the case of an Assignment and Assumption 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 2.17, 2.18 and 2.20 and 9.05 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected
parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations
under this Agreement that does not comply with this paragraph 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 paragraph (d) of this Section.

 (c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall
maintain at one of its offices in Dallas, Texas, a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated
interest) 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 absent manifest error, and the Borrowers, the Administrative Agent and the
Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower Representative and any
Lender, at any reasonable time and from time to time upon reasonable prior notice. 
 (d) Participations. Any
Lender may at any time, without the consent of, or notice to, any Borrower or the Administrative Agent, sell participations to any Person (other than a natural Person or any Borrower or any of the Affiliates or Subsidiaries of any Borrower) (each, a
“Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s
obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) the Borrowers, the Administrative Agent and Lenders
shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. 
 Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the 

  
 88 

 
Participant, agree to any amendment, modification or waiver described in Section 9.01(i) that directly affects such Participant. The Borrowers agree that each Participant shall be entitled
to the benefits of Sections 2.17, 2.18 and 2.20 (subject to the requirements and limitations therein, including the requirements under Section 2.18(f) (it being understood that the documentation required under Section 2.18(f) shall be
delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the
provisions of Sections 2.19 as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 2.17 or 2.18, with respect to any participation, than its participating
Lender would have been entitled to receive, unless the sale of the participation to such Participant is made with the Borrower Representative’s prior written consent. Each Lender that sells a participation agrees, at the Borrower’s request
and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 2.19(b) with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of
Section 9.07(b) as though it were a Lender; provided that such Participant agrees to be subject to Section 9.07(a) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent
of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the
“Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s
interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other
obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is
recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent)
shall have no responsibility for maintaining a Participant Register. 
 (e) Certain Pledges. Any Lender may at any
time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such
pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 
 (f) Notes. The Borrowers, upon receipt of written notice from the relevant Lender, agree to issue Notes to any Lender requiring Notes to facilitate transactions of the type described in
paragraph (b) above. 
 Section 9.07. Adjustments; Set-Off. 

(a) Except to the extent that this Agreement expressly provides for payments to be allocated to a particular Lender or Lenders under a
particular Facility, if any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such

  
 89 

 
Lender’s receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than its pro rata share thereof as
provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the other
Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and
other amounts owing them, provided that: 
 (i) if any such participations are purchased and all or any
portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and 

(ii) the provisions of this paragraph shall not be construed to apply to (x) any payment made by the Borrowers, or
any of them, pursuant to and in accordance with the express terms of this Agreement or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant,
other than to the Borrowers (as to which the provisions of this paragraph shall apply). 
 Each of the Borrowers consents to the
foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrowers rights of setoff and counterclaim with respect to
such participation as fully as if such Lender were a direct creditor of the Borrowers in the amount of such participation. 

(b) If an Event of Default shall have occurred and be continuing, 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 applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other
obligations (in whatever currency) at any time owing by such Lender or any such Affiliate to or for the credit or the account of any Borrower against any and all of the obligations of any Borrower now or hereafter existing under this Agreement or
any other Loan Document to such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Borrowers may be contingent or unmatured or are owed
to a branch or office of such Lender different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Lender and their respective Affiliates under this Section are in addition to other rights and
remedies (including other rights of setoff) that such Lender or its respective Affiliates may have. Each Lender agrees to notify the Borrower Representative and the Administrative Agent promptly after any such setoff and application, provided
that the failure to give such notice shall not affect the validity of such setoff and application. Notwithstanding the provisions of Sections 2.15(h) and 9.07(b) of this Agreement and Section 10.14 of the Guarantee and Collateral Agreement, if
at any time any Lender or any of its Affiliates maintains one or more deposit accounts for any Borrower into which Medicare and/or Medicaid receivables are deposited or sent for deposit by the payor, such Person waives the rights of setoff set forth
in such Sections with respect to such deposit account or deposit accounts. 

  
 90 

 Section 9.08. Counterparts; Integration; Effectiveness; Electronic Execution.
This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the
other Loan Documents, and any separate letter agreements with respect to fees payable to the Administrative Agent, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements
and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 3.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent
shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or in electronic (i.e.,
“pdf’ or “tif’) format shall be effective as delivery of a manually executed counterpart of this Agreement. 

Section 9.09. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as
to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. 
 Section 9.10. Governing Law; Jurisdiction; etc.

 (a) This Agreement shall be governed by, and construed in accordance with, the law of the State of Texas. 

(b) Each of the Borrowers irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the
courts of the State of Texas sitting in Dallas County and of the United States District Court of the Northern District of Texas, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or
any other Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Texas
State court or, to the fullest extent permitted by applicable 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. Nothing in this Agreement or in any other Loan Document shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this
Agreement or any other Loan Document against any Borrower or its properties in the courts of any jurisdiction. 
 (c) Each
Borrower irrevocably and unconditionally waives, to the fullest extent permitted by applicable law, any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this Agreement or
any other Loan Document in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance
of such action or proceeding in any such court. 

  
 91 

 (d) Each party hereto irrevocably consents to service of process in the manner provided for
notices in Section 9.02. Nothing in this Agreement will affect the right of any party hereto to serve process in any other manner permitted by applicable law. 
 Section 9.11. Acknowledgements. Each Borrower hereby acknowledges that: 

(a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents; 

(b) neither the Administrative Agent nor any Lender has any fiduciary relationship with or duty to any Borrower arising out of or in
connection with this Agreement or any of the other Loan Documents, and the relationship between Administrative Agent and Lenders, on one hand, and any of the Borrowers, on the other hand, in connection herewith or therewith is solely that of debtor
and creditor; and 
 (c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the
transactions contemplated hereby among the Lenders or among Borrowers and the Lenders. 
 Section 9.12. Treatment of
Certain Information; Confidentiality. Each of the Administrative Agent and the Lenders agree to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its
Related Parties (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential); (b) to the extent required or requested
by any regulatory authority purporting to have jurisdiction over such Person or its Related Parties (including any self-regulatory authority, such as the National Association of Insurance Commissioners); (c) to the extent required by applicable
laws or regulations or by any subpoena or similar legal process; (d) to any other party hereto; (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this
Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder; (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights and obligations under this Agreement, or (ii) any actual or prospective party (or its Related Parties) to any swap, derivative or other transaction under which payments are to be made
by reference to any Borrower and its obligations, this Agreement or payments hereunder; (g) on a confidential basis to (i) any rating agency in connection with rating any Borrower or the Facilities or (ii) the CUSIP Service Bureau or
any similar agency in connection with the issuance and monitoring of CUSIP numbers with respect to the Facilities; (h) with the consent of the Borrower Representative; or (i) to the extent such Information (x) becomes publicly
available other than as a result of a breach of this Section, or (y) becomes available to the Administrative Agent or any Lender or any of their respective Affiliates on a nonconfidential basis from a source other than a Borrower. 

For purposes of this Section, “Information” means all information received from any Borrower relating to any Borrower or
any of its Subsidiaries or any of their respective businesses, other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by any Borrower. Any Person required to

  
 92 

 
maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to its own confidential information. 

Section 9.13. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate
applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum
Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in
respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and
the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the
date of repayment, shall have been received by such Lender. The right to accelerate maturity of the Loans and the other Obligations does not include the right to accelerate any interest which has not otherwise accrued on the date of such
acceleration, and the Administrative Agent and the Lenders do not intend to charge or receive any unearned interest in the event of acceleration. 
 Section 9.14. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the
construction of, or be taken into consideration in interpreting, this Agreement. 
 Section 9.15. Time of the
Essence. Time is of the essence of this Agreement and the other Loan Documents. 
 Section 9.16. 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 AGREEMENT OR ANY
OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER
LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 
 Section 9.17. USA
PATRIOT Act Notice. Each Lender hereby notifies the Borrowers that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to
obtain, verify and record information that identifies the Borrowers, which information includes the name and address of each Borrower and other information that will allow such Lender to identify the Borrowers in accordance with the Patriot Act.

                     of the Borrower Representative 
 2. I have reviewed and am familiar with the contents of this Certificate.

the financial statements attached hereto as Attachment 1 that are delivered on the date hereof pursuant to Section 5.01 of the Credit Agreement (the “Financial Statements”). [Except as set forth below], [s]uch review did
not disclose, and I have no knowledge of (i) the existence of any condition or event that constitutes a Default or Event of Default during or at the end of the accounting period covered by the Financial Statements or as of the date of this
Certificate or (ii) any change in GAAP or in the application thereof that has occurred since the date of the audited financial statements referred to in Section 4.01(b) of the Credit Agreement. To the best of my knowledge, each Borrower

observed, performed or satisfied by it. 
 5. Attached hereto as Attachment 2 are the financial data and computations
showing (in reasonable detail) compliance by the Borrowers with the covenants set forth in Sections 6.01, 6.02(c), 6.02(h), 6.02(i), 6.05(e), 6.06(b), 6.08(h), and 6.08(j) of the Credit Agreement, all of which financial data and computations are
true, complete and correct. 
 6. Attached hereto as Attachment 3 is (i) a description of any change in the
jurisdiction of organization or the name of any Borrower, (ii) a list of all Intellectual Property acquired by any

Subsidiary of Holdings, in each case since the most recent Compliance Certificate was delivered (or in the case of the first Compliance Certificate so delivered, since the Closing Date). 

Described below are the exceptions, if any, to paragraph 3 by listing, in detail, the (i) nature of the condition or event, the
period during which it has existed and the action that the Borrowers have taken, are taking, or propose to take with respect to each such condition or event or (ii) the change in GAAP or the application thereof and the effect of such change on
the attached financial statements: 
  

			
		  	 
		  	 
		  	 

 The foregoing certifications, together with the computations set forth in Attachment 2 and the
Financial Statements delivered with this Certificate in support hereof, are made and delivered this      day of                 201_.

payment” means that:

any claim to the assets of, or equity interests in, the Borrower on a parity with or prior to the claim of the Senior Obligations; and 

  
 3

(excluding contingent indemnification obligations for which no claim has been made and Banking Services Obligations), without the express prior written consent of the Senior Agent: 

(A) no Subordinated Creditor will take, accept, demand, require or receive from the Borrower or any other Person, and the

Obligations, including, without limitation, any letter of credit or similar credit support facility to support payment of the Subordinated Obligations; provided, however, that if no Senior Default shall have occurred and be continuing or

Agreement or otherwise, and all rights of Dr. Paul Thompson under Section 4(c) of the House Purchase Agreement shall be subordinate and junior to all Liens and claims of the Senior Agent and the Senior Lenders under Senior Loan Documents.

 (c) The expressions “prior payment in full,” “payment in full,” “paid in full” and any other
similar terms or phrases when used in this Agreement with respect to the Senior Obligations shall (i) mean the indefeasible payment in full, in immediately available funds, of all of the Senior Obligations, and (ii) the termination of the
Commitments. 
  

	3.	Additional Provisions Concerning Subordination. 

 (a) The Subordinated Creditors and the Borrower agree that upon the occurrence of any Insolvency Event commenced by or against the Borrower: 

(i) all Senior Obligations shall be paid in full (excluding contingent indemnification obligations for which no claim has
been made and Banking Services Obligations) before any payment or distribution is made with respect to the Subordinated Obligations; and 

  
 4 

 (ii) any payment or distribution of assets of the Borrower, whether in cash,
property or securities, to which any Subordinated Creditor would be entitled except for the provisions hereof, shall be paid or delivered by the Borrower, or any receiver, trustee in bankruptcy, liquidating trustee, disbursing agent or other Person
making such payment or distribution, directly to the Senior Agent, for the account of the Senior Lenders, to the extent necessary to pay in full all Senior Obligations (excluding contingent indemnification obligations for which no claim has been
made and Banking Services Obligations), before any payment or distribution shall be made to any Subordinated Creditor. 
 (b)
Upon the occurrence of any event or proceeding described in clause (i) of the definition of “Insolvency Event” commenced by or against the Borrower: 

(i) each Subordinated Creditor irrevocably authorizes and empowers the Senior Agent: 

(A) to demand, sue for, collect and receive every payment or distribution on account of the Subordinated Obligations
payable or deliverable in connection with such event or proceeding and give acquittance therefor; and 
 (B) to
file claims and proofs of claim in any statutory or non-statutory proceeding and take such other actions, in its own name as Senior Agent, or in the name of the Subordinated Creditors or otherwise, as the Senior Agent may deem necessary or advisable
for the enforcement of the provisions of this Agreement; provided, however, that the foregoing authorization and empowerment imposes no obligation on the Senior Agent to take any such action; 

(ii) each Subordinated Creditor shall take such action, duly and promptly, as the Senior Agent may request from time to
time 
 (A) to collect the Subordinated Obligations for the account of the Senior Lenders; and 

(B) to file appropriate proofs of claim in respect of the Subordinated Obligations; and 

(iii) each Subordinated Creditor shall execute and deliver such powers of attorney, assignments or proofs of claim or
other instruments as the Senior Agent may request to enable the Senior Agent to enforce any and all claims in respect of the Subordinated Obligations and to collect and receive any and all payments and distributions which may be payable or
deliverable at any time upon or in respect of the Subordinated Obligations. 
 (c) If any payment or distribution, whether
consisting of money, property or securities, shall be collected or received by any Subordinated Creditor in respect of the 

  
 5 

 
Subordinated Obligations, except payments permitted to be made at the time of payment as provided in Section 2(b)(ii)(A) above, such Subordinated Creditor forthwith shall deliver the same to
the Senior Agent for the account of the Senior Lenders, in the form received, duly indorsed to the Senior Agent, if required, to be applied to the payment or prepayment of the Senior Obligations until the Senior Obligations are paid in full
(excluding contingent indemnification obligations for which no claim has been made and Banking Services Obligations). Until so delivered, such payment or distribution shall be held in trust by such Subordinated Creditor as the property of the Senior
Agent for the benefit of the Senior Lenders, segregated from other funds and property held by such Subordinated Creditor. 
 4.
Subrogation. Until the Senior Obligations are paid in full (excluding contingent indemnification obligations for which no claim has been made and Banking Services Obligations), the Subordinated Creditors shall not assert any claim of
subrogation under applicable law or otherwise with respect to the Senior Agent, the Senior Lenders and the Senior Obligations. Upon the prior payment in full of the Senior Obligations (excluding contingent indemnification obligations for which no
claim has been made and Banking Services Obligations), the Subordinated Creditors shall be subrogated to the rights of the Senior Lenders to receive payments or distributions of assets of the Borrower in respect of the Senior Obligations. For the
purposes of such subrogation, payments or distributions to the Senior Agent, for the account of the Senior Lenders, of any money, property or securities to which any Subordinated Creditor would be entitled except for the provisions of this Agreement
shall be deemed, as between the Borrower and its creditors other than the Senior Lenders and such Subordinated Creditor, to be a payment by the Borrower to or on account of Subordinated Obligations, it being understood that the provisions of this
Agreement are, and are intended solely, for the purpose of defining the relative rights of the Subordinated Creditors, on the one hand, and the Senior Agent and the Senior Lenders, on the other hand. 

5. Consent of Subordinated Creditors. 
 (a) Each Subordinated Creditor consents and agrees that, without the necessity of any reservation of rights against any Subordinated Creditor, and without notice to or further assent by any Subordinated
Creditor: 
 (i) any demand for payment of any Senior Obligations made by the Senior Agent or any Senior Lender
may be rescinded in whole or in part by the Senior Agent or any such Senior Lender, and any Senior Obligation may be continued, and the Senior Obligations, or the liability of the Borrower, any other borrower or any guarantor or any other Person
upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, or any obligation or liability of the Borrower or any other party under the Senior Credit Agreement or any other agreement, may,
from time to time, in whole or in part, be renewed, extended, increased, accelerated, compromised, waived, modified, surrendered, or released by the Senior Agent or any Senior Lender; and 

(ii) the Senior Credit Agreement, the Senior Notes, any other Senior Loan Document and any Rate Management Document may be
amended, restated, modified, supplemented or terminated, in whole or in part, as the Senior Agent or any Senior 

  
 6 

 
Lender (or affiliate of any Senior Lender) may deem advisable from time to time, and any collateral security at any time held by the Senior Agent or any Senior Lender for the payment of any of
the Senior Obligations may be sold, exchanged, waived, surrendered or released, in each case all without notice to or further assent by any Subordinated Creditor, which will remain bound under this Agreement, and all without impairing, abridging,
releasing or affecting the subordination provided for herein. 
 (b) Each Subordinated Creditor waives any and all notice of the
creation, renewal, increase, extension or accrual of any of the Senior Obligations and notice of or proof of reliance by the Senior Agent and the Senior Lenders upon this Agreement. The Senior Obligations, and any of them, shall be deemed
conclusively to have been created, contracted or incurred in reliance upon this Agreement, and all dealings between the Borrower and the Senior Agent and Senior Lenders shall be deemed to have been consummated in reliance upon this Agreement. Each
Subordinated Creditor acknowledges and agrees that the Senior Agent and Senior Lenders have relied upon the subordination provided for herein in entering into the Senior Credit Agreement and in making funds available to the Borrower and the other
borrowers thereunder and in entering into any Rate Management Document. Each Subordinated Creditor waives notice of or proof of reliance on this Agreement and protest, demand for payment and notice of default. 

6. Negative Covenants of the Subordinated Creditors. So long as any of the Senior Obligations shall remain outstanding (excluding contingent
indemnification obligations for which no claim has been made and Banking Services Obligations), no Subordinated Creditor shall, without the prior written consent of the Senior Agent: 

(a) sell, assign, or otherwise transfer, in whole or in part, the Subordinated Obligations or any interest therein to any other Person (a
“Transferee”) or create, incur or suffer to exist any security interest, lien, charge or other encumbrance whatsoever upon the Subordinated Obligations in favor of any Transferee unless: 

(i) such action is made expressly subject to this Agreement; and 

(ii) the Transferee expressly acknowledges to the Senior Agent, by a writing in form and substance satisfactory to the
Senior Agent, the subordination provided for herein and agrees to be bound by all of the terms hereof; 
 (b) permit any of the
Subordinated Loan Documents to be amended, restated, modified or otherwise supplemented (other than any such amendment, modification, waiver or other change that (i) would extend the maturity or reduce the amount of any payment of principal
thereof or reduce the rate or extend any date for payment of interest thereon and (ii) does not involve the payment of a consent fee); 
 (c) commence, or join with any creditors other than the Senior Lenders in commencing any Insolvency Event; 
 (d) challenge the validity, enforceability or priority of any Senior Loan Document; 

  
 7 

 (e) challenge the extent, validity, creation, perfection, or priority of any Lien created or
purported to be created pursuant to any Senior Security Document or seek to avoid or subordinate any such Lien; 
 (f) interfere
in any respect with the exercise by the Senior Agent or any Senior Lender of any right or remedy under any Senior Loan Document or applicable law; or 
 (g) obtain, accept or receive any guaranty, collateral or other security for any of the Subordinated Obligations. 
 7. Obligations Unconditional. All agreements and obligations of the Subordinated Creditors hereunder shall be irrevocable, unconditional, continuing and absolute. All rights and interests of the
Senior Agent and the Senior Lenders hereunder, and all agreements and obligations of the Borrower and the Subordinated Creditors hereunder, shall remain in full force and effect irrespective of: 

(a) any lack of validity or enforceability of any Senior Security Documents or any other Senior Loan Documents or any Rate Management
Document; 
 (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Senior
Obligations, or any amendment or waiver or other modification, whether by course of conduct or otherwise, of the terms of the Senior Credit Agreement or any other Senior Security Document or any Rate Management Document; 

(c) any exchange, release or nonperfection of any security interest in any Collateral, or any release, amendment, waiver or other
modification, whether in writing or by course of conduct or otherwise, of all or any of the Senior Obligations or any guarantee thereof; 
 (d) the existence of any claim, set-off, defense, counterclaim or other right that any Subordinated Creditor, the Borrower, any other borrower, any guarantor or any other Person may have against any
Person, including, without limitation, the Senior Agent or any Senior Lender; 
 (e) any manner of application of Collateral or
any other collateral, or proceeds thereof, to all or any of the Senior Obligations, or any manner of sale or other disposition of any Collateral or any other collateral for all or any of the Senior Obligations or any obligations of the Borrower or
any other borrower under the Senior Loan Documents or any other assets of the Borrower or any other Person; 
 (f) any change,
restructuring or termination of the corporate or other organizational structure or existence of the Borrower, any other borrower, any guarantor or any other obligor with respect to the Senior Obligations; 

(g) any failure of the Senior Agent or any Senior Lender to disclose to any Subordinated Creditor any information relating to the
business, condition (financial or otherwise), operations, performance, properties or prospects of the Borrower, any other borrower, any guarantor or other Person now or hereafter known to the Senior Agent or such Senior Lender (each Subordinated
Creditor hereby waiving any duty on the part of the Senior Agent and the Senior Lenders to disclose such information); or 

  
 8 

 (h) any other circumstances which otherwise might constitute a defense available to, or a
discharge of, the Borrower in respect of the Senior Obligations, or of either any Subordinated Creditor or the Borrower in respect of this Agreement, other than the defense of payment in full. 

8. Representations and Warranties. Each Subordinated Creditor represents and warrants to the Senior Agent and the Senior Lenders that: 

(a) its Subordinated Note: 
 (i) has been issued to it for good and valuable consideration; 

(ii) is owned by the such Subordinated Creditor free and clear of any security interests, liens, charges or encumbrances

Creditor pursuant to any Requirement of Law affecting or any Contractual Obligation of such Subordinated Creditor, except the interest of the Senior Agent and the Senior Lenders under this Agreement; and 

(e) no consent or authorization of, filing with, or other act by or in respect of, any arbitrator or Governmental Authority and no

9. Waiver of Claims. To the maximum extent permitted by law, each Subordinated Creditor waives any claim it might have against the Senior Agent

execute and deliver such further instruments and documents and take such further actions as the Senior Agent reasonably may request for the purposes of obtaining or preserving the full benefits of this Agreement and of the rights and powers herein
granted.

notwithstanding the occurrence of an Insolvency Event.

Partner, which may from time to time delegate authority to officers or to others to act on behalf of the Partnership. 
 (b) The
Partners hereby agree that the Partnership, acting by the General Partner and/or any officer of the General Partner, including but not limited to Lisa Barse Bernstein, Leon D. Black, Wendy F. Dulman, Barry J. Giarraputo, Joseph D. Glatt, Joshua J.

Partnership in such banks, and designate the persons authorized to sign checks, notes, drafts, bills of exchange, acceptances, undertakings or orders for payment of money from funds of the Partnership on deposit in such accounts, as may be deemed by
the General Partner or any Authorized Person, or any of them, to be necessary, 

  
 10 

 
appropriate or otherwise in the best interests of the Partnership and, in connection therewith, execute any form of required resolution necessary to open any such bank accounts; (ii) prepare
and file, or cause to be prepared and filed, by mail, facsimile or telephone, for and on behalf of the Partnership, an Application for Employer Identification Number on United States Internal Revenue Service Form SS-4, and to prepare, execute and
file with the appropriate authorities such other federal, state or local applications, forms and papers on behalf of the Partnership as may be required by law or deemed by the General Partner or any Authorized Person, or any of them, to be
necessary, appropriate or otherwise in the best interests of the Partnership, as applicable; and (iii) pay on behalf of the Partnership any and all fees and expenses incident to and necessary to perfect the organization of the Partnership.
Notwithstanding any other provision of this Agreement, the Partnership, acting by the General Partner and/or any Authorized Person on its behalf, is hereby authorized to enter into, and to perform its obligations under, the aforementioned
agreements, deeds, receipts, certificates, filings and other documents, without any consent of any Limited Partner, but such authorization shall not be deemed a restriction on the power of the Partnership or the General Partner and/or any Authorized
Person acting on behalf of the Partnership to enter into, and to perform its obligations under, other agreements on behalf of the Partnership. The Partners agree that the General Partner and/or any Authorized Person may execute the aforementioned
agreements, deeds, receipts, certificates, filings and other documents on behalf of the Partnership under any title, including without limitation “Authorized Person,” that the General Partner or any Authorized Person, or any of them, deems
appropriate and that any prior acts of the Partnership and the General Partner and/or any Authorized Person acting on behalf of the Partnership, consistent with the foregoing authorizations, are hereby ratified and confirmed. 

Section 3.02. Compensation. The General Partner shall not be entitled to any compensation for services rendered to the
Partnership in its capacity as General Partner. 
 Section 3.03. Expenses. The Partnership shall bear and/or
reimburse (i) the General Partner for any expenses incurred by the General Partner in connection with serving as the general partner of the Partnership, and (ii) Issuer and APO Corp., with respect to the Partnership’s allocable share
of any expenses solely incurred by or attributable to the Issuer or APO Corp. but excluding obligations incurred under the Tax Receivable Agreement, dated as of July 13, 2007 among APO Corp. and the Apollo Operating Group entities party

 Section 3.04. Authority of Partners. No Limited Partner, in its capacity as such, shall participate in or have any control over the business of the Partnership. Except as

vote on any matter involving the Partnership, including with respect to any merger, consolidation, combination or conversion of the Partnership. The conduct, control and management of the Partnership shall be vested exclusively in the General
Partner. In all matters relating to or arising out of the conduct of the operation of the Partnership, the decision of the General Partner shall be the decision of the Partnership. Except as required or permitted by Law, or by separate agreement
with the Partnership, no Partner who is not also a General Partner (and acting in such capacity) shall take any part in the management or control of 

  
 11 

 
the operation or business of the Partnership in its capacity as a Partner, nor shall any Partner who is not also a General Partner (and acting in such capacity) have any right, authority or power
to act for or on behalf of or bind the Partnership in his or its capacity as a Partner in any respect or assume any obligation or responsibility of the Partnership or of any other Partner. Notwithstanding the foregoing, the Partnership may employ
one or more Partners from time to time, and such Partners, in their capacity as employees of the Partnership (and not, for clarity, in their capacity as Limited Partners of the Partnership), may take part in the control and management of the
business of the Partnership to the extent such authority and power to act for or on behalf of the Partnership has been delegated to them by the General Partner; provided that such employee shall not take part in the conduct of the business of
the Partnership in its dealings with persons who are not Partners as though such employee was a general partner of the Partnership. 
 Section 3.05. Action by Written Consent or Ratification. Any action required or permitted to be taken by the Partners pursuant to this Agreement shall be taken if all Partners whose
consent or ratification is required consent thereto or provide a consent or ratification in writing. 
 ARTICLE IV

 DISTRIBUTIONS 
 Section 4.01. Distributions. 
 (a) All distributions of
Distributable Cash shall be made, at the discretion of the General Partner, to the Limited Partners pro rata in accordance with their respective Percentage Interests; provided, that: 

(i) distributions in 2010 of Operating Income shall be pro rata based on the Special Percentage Interests; 

(ii) distributions in 2011 attributable to Operating Income for the 2010 Fiscal Year shall be pro rata based on the Special Percentage
Interests; and 
 (iii) distributions in 2014 and subsequent to 2014 shall first be distributed pro rata based on the Special
Percentage Interests until an amount has been distributed to APO Corp. equal to the amount APO Corp. is obligated to pay during such year pursuant to the First Amendment and Joinder as a “Deferred Tax Benefit Payment” (as defined in the
First Amendment and Joinder). 
 (b) Tax Distributions. 

(i) In addition to the foregoing, if the General Partner reasonably determines that the taxable income of the Partnership for a Fiscal
Year will give rise to taxable income for the Partners (“Net Taxable Income”), the General Partner shall cause the Partnership to distribute Distributable Cash in respect of income tax liabilities (the “Tax
Distributions”) to the extent that other distributions made by the Partnership for such year were otherwise insufficient to cover such tax liabilities; provided that distributions pursuant to Section 4.02 and allocations
pursuant to Section 5.04 related to such distributions shall not be taken into account 

  
 12 

 
for purposes of this Section 4.01(b). The Tax Distributions payable with respect to any Fiscal Year shall be computed based upon the General Partner’s estimate of the allocable Net
Taxable Income in accordance with Article V, multiplied by the Assumed Tax Rate (the “Tax Amount”). For purposes of computing the Tax Amount, the effect of any benefit under Section 743(b) of the Code will be ignored. Any Tax
Distributions shall be made to all Partners, whether or not they are subject to such applicable United States federal, state and local taxes, pro rata in accordance with their Percentage Interest except for Tax Distributions attributable to 2009 or
2010 Net Taxable Income, which shall be pro rata in accordance with their Special Percentage Interests. Notwithstanding anything provided in this Section 4.01(b), the General Partner shall not be required to cause the Partnership to make Tax
Distributions with respect to 2009 and 2010 Net Taxable Income but may make such Tax Distributions to the extent of APO Corp.’s actual tax liability. 
 (ii) Tax Distributions shall be calculated and paid no later than one day prior to each quarterly due date for the payment by corporations on a calendar year of estimated taxes under the Code in the
following manner (A) for the first quarterly period, 25% of the Tax Amount, (B) for the second quarterly period, 50% of the Tax Amount, less the prior Tax Distributions for the Fiscal Year, (C) for the third quarterly period, 75% of
the Tax Amount, less the prior Tax Distributions for the Fiscal Year and (D) for the fourth quarterly period, 100% of the Tax Amount, less the prior Tax Distributions for the Fiscal Year. Following each Fiscal Year, and no later than one day
prior to the due date for the payment by corporations of income taxes for such Fiscal Year, the General Partner shall make an amended calculation of the Tax Amount for such Fiscal Year (the “Amended Tax Amount”), and shall cause the
Partnership to distribute a Tax Distribution, out of Distributable Cash, to the extent that the Amended Tax Amount so calculated exceeds the cumulative Tax Distributions previously made by the Partnership in respect of such Fiscal Year. If the
Amended Tax Amount is less than the cumulative Tax Distributions previously made by the Partnership in respect of the relevant Fiscal Year, then the difference (the “Credit Amount”) shall be applied against, and shall reduce, the
amount of Tax Distributions made for subsequent Fiscal Years. Within 30 days following the date on which the Partnership files a tax return on Form 1065, the General Partner shall make a final calculation of the Tax Amount of such Fiscal Year (the
“Final Tax Amount”) and shall cause the Partnership to distribute a Tax Distribution, out of Distributable Cash, to the extent that the Final Tax Amount so calculated exceeds the Amended Tax Amount. If the Final Tax Amount is less
than the Amended Tax Amount in respect of the relevant Fiscal Year, then the difference (“Additional Credit Amount”) shall be applied against, and shall reduce, the amount of Tax Distributions made for subsequent Fiscal Years. Any
Credit Amount and Additional Credit Amount applied against future Tax Distributions shall be treated as an amount actually distributed pursuant to this Section 4.01(b) for purposes of the computations herein. 

(c) 2007 Distributions. The Partners acknowledge that all distributions of Distributable Cash made in 2007 were governed by
Article IV of the Second Amended Agreement and the terms of such Article IV of the Second Amended Agreement, which are hereby incorporated by reference, shall govern with respect to all distributions made in 2007. 

Section 4.02. Liquidation Distribution. Distributions made upon dissolution of the Partnership shall be made as
provided in Section 9.03. 

  
 13 

 Section 4.03. Limitations on Distribution. Notwithstanding any provision
to the contrary contained in this Agreement, the General Partner shall not make a Partnership distribution to any Partner if such distribution would violate the Act or other applicable Law. 

ARTICLE V 

CAPITAL CONTRIBUTIONS; CAPITAL ACCOUNTS; 
 TAX ALLOCATIONS; TAX MATTERS 
 Section 5.01. Initial Capital
Contributions. The Partners have made, on or prior to the date hereof, Capital Contributions as contemplated by Section 11.18 and have acquired the number of Class A Units as specified in the books and records and register of
partnership interests of the Partnership. 
 Section 5.02. No Additional Capital Contributions. Except
as otherwise provided in this Article V, no Partner shall be required to make additional Capital Contributions to the Partnership without the consent of such Partner or permitted to make additional Capital Contributions to the Partnership without
the consent of the General Partner. 
 Section 5.03. Capital Accounts. A separate capital account (a
“Capital Account”) shall be established and maintained for each Partner in accordance with the provisions of Treasury Regulations Section 1.704-l(b)(2)(iv). The Capital Account of each Partner shall be credited with such
Partner’s Capital Contributions, if any, all Profits allocated to such Partner pursuant to Section 5.04 and any items of income or gain which are specially allocated pursuant to Section 5.05; and shall be debited with all Losses
allocated to such Partner pursuant to Section 5.04, any items of loss or deduction of the Partnership specially allocated to such Partner pursuant to Section 5.05, and all cash and the Carrying Value of any property (net of liabilities
assumed by such Partner and the liabilities to which such property is subject) distributed by the Partnership to such Partner. Any references in any section of this Agreement to the Capital Account of a Partner shall be deemed to refer to such
Capital Account as the same may be credited or debited from time to time as set forth above. In the event of any transfer of any interest in the Partnership in accordance with the terms of this Agreement, the transferee shall succeed to the Capital
Account of the transferor to the extent it relates to the transferred interest. 
 Section 5.04. Allocations of
Profits and Losses. Except as otherwise provided in this Agreement, Profits and Losses (and, to the extent necessary, individual items of income, gain or loss or deduction of the Partnership) shall be allocated in a manner such that the Capital
Account of each Partner after giving effect to the special allocations set forth in Section 5.05 is, as nearly as possible, equal (proportionately) to (i) the distributions that would be made pursuant to Article IV if the Partnership were
dissolved, its affairs wound up and its assets sold for cash equal to their Carrying Value, all Partnership liabilities were satisfied (limited with respect to each non-recourse liability to the Carrying Value of the assets securing such liability)
and the net assets of the Partnership were distributed to the Partners pursuant to this Agreement, minus (ii) such Partner’s share of Partnership Minimum Gain and Partner Nonrecourse Debt Minimum Gain, computed immediately prior to
the hypothetical sale of assets. Notwithstanding the foregoing, the General Partner shall make such adjustments to Capital Accounts as it determines in its sole discretion to be appropriate to ensure allocations are made in accordance with a
Partner’s interest in the Partnership. Solely for purposes of clause (i) of this Section 5.04, the distribution provision set forth in Section 9.03(b) shall be treated as being added to Section 4.01(a) as clause (iv).

  
 14 

 Section 5.05. Special Allocations. Notwithstanding any other provision in
this Article V: 
 (a) Minimum Gain Chargeback. If there is a net decrease in Partnership Minimum Gain or Partner
Nonrecourse Debt Minimum Gain (determined in accordance with the principles of Treasury Regulations Sections 1.704-2(d) and 1.704-2(i)) during any Partnership taxable year, the Partners shall be specially allocated items of Partnership income and
gain for such year (and, if necessary, subsequent years) in an amount equal to their respective shares of such net decrease during such year, determined pursuant to Treasury Regulations Sections 1.704-2(g) and 1.704-2(i)(5). The items to be so
allocated shall be determined in accordance with Treasury Regulations Section 1.704-2(f). This Section 5.05(a) is intended to comply with the minimum gain chargeback requirements in such Treasury Regulations Sections and shall be
interpreted consistently therewith; including that no chargeback shall be required to the extent of the exceptions provided in Treasury Regulations Sections 1.704-2(f) and 1.704-2(i)(4). 

(b) Qualified Income Offset. If any Partner unexpectedly receives any adjustments, allocations, or distributions described in
Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate the deficit balance in such Partner’s
Adjusted Capital Account Balance created by such adjustments, allocations or distributions as promptly as possible; provided that an allocation pursuant to this Section 5.05(b) shall be made only to the extent that a Partner would have a
deficit Adjusted Capital Account Balance in excess of such sum after all other allocations provided for in this Article V have been tentatively made as if this Section 5.05(b) were not in this Agreement. This Section 5.05(b) is intended to
comply with the “qualified income offset” requirement of the Code and shall be interpreted consistently therewith. 

(c) Gross Income Allocation. If any Partner has a deficit Capital Account at the end of any Fiscal Year which is in excess of the
sum of (i) the amount such Partner is obligated to restore, if any, pursuant to any provision of this Agreement, and (ii) the amount such Partner is deemed to be obligated to restore pursuant to the penultimate sentences of Treasury
Regulations Section 1.704-2(g)(l) and 1.704-2(i)(5), each such Partner shall be specially allocated items of Partnership income and gain in the amount of such excess as quickly as possible; provided that an allocation pursuant to this
Section 5.05(c) shall be made only if and to the extent that a Partner would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Article V have been tentatively made as if Section 5.05(b)
and this Section 5.05(c) were not in this Agreement. 
 (d) Nonrecourse Deductions. Nonrecourse Deductions shall be
allocated to the Partners in accordance with their respective Percentage Interests. 
 (e) Partner Nonrecourse
Deductions. Partner Nonrecourse Deductions for any taxable period shall be allocated to the Partner who bears the economic risk of loss with respect to the liability to which such Partner Nonrecourse Deductions are attributable in accordance
with Treasury Regulations Section 1.704-2(j). 

  
 15 

 (f) Creditable Foreign Taxes. Creditable Foreign Taxes for any taxable period
attributable to the Partnership, or an entity owned directly or indirectly by the Partnership, shall be allocated to the Partners in proportion to the Partners’ distributive shares of income (including income allocated pursuant to
Section 704(c) of the Code) to which the Creditable Foreign Tax relates (under principles of Treasury Regulations Section 1.904-6). The provisions of this Section 5.05(f) are intended to comply with the provisions of Treasury
Regulations Section 1.704-1(b)(4)(viii), and shall be interpreted consistently therewith. 
 (g) Ameliorative
Allocations. Any special allocations of income or gain pursuant to Section 5.05(b) or (c) hereof shall be taken into account in computing subsequent allocations pursuant to Section 5.04 and this Section 5.05(g), so that the
net amount of any items so allocated and all other items allocated to each Partner shall, to the extent possible, be equal to the net amount that would have been allocated to each Partner if such allocations pursuant to Section 5.05(b) or
(c) had not occurred. 
 (h) With respect to the amount in excess of the first $36,955,739 of Net Profit for the 2009
Fiscal Year, all items of income, gain, loss and deduction attributable to the Operating Income for the 2009 Fiscal Year shall be allocated to the Partners pro rata in accordance with their respective Special Percentage Interests. 

(i) All items of income, gain, loss and deduction attributable to the Operating Income for the 2010 Fiscal Year shall be allocated to the
Limited Partners pro rata in accordance with their respective Special Percentage Interests. 
 (j) Notwithstanding clause
(d) of the definition of “Profits” and “Losses,” upon an adjustment (or adjustments) to the Carrying Value of the Partnership’s assets pursuant to the definition of “Carrying Value” that results in a net gain,
such net gain shall be specially allocated to AP Professional until AP Professional has been allocated an amount pursuant to this Section 5.05(j) equal to the sum of the 2009 Special Book-Up Amount plus the 2010 Special Book-Up Amount.

 Section 5.06. Tax Allocations. For income tax purposes, each item of income, gain, loss and deduction of
the Partnership shall be allocated among the Partners in the same manner as the corresponding items of Profits and Losses and specially allocated items are allocated for Capital Account purposes; provided that in the case of any asset the
Carrying Value of which differs from its adjusted tax basis for United States federal income tax purposes, income, gain, loss and deduction with respect to such asset shall be allocated solely for income tax purposes in accordance with the
principles of Sections 704(b) and (c) of the Code (in any manner determined by the General Partner and permitted by the Code and Treasury Regulations) so as to take account of the difference between Carrying Value and adjusted basis of such
asset. Notwithstanding the foregoing, the General Partner shall make such allocations for tax purposes as it determines in its sole discretion to be appropriate to ensure allocations are made in accordance with a Partner’s interest in the
Partnership. 
 Section 5.07. Tax Advances. To the extent the General Partner reasonably believes that the
Partnership is required by law to withhold or to make tax payments on behalf of or with respect to any Partner or the Partnership is subjected to tax itself by reason of the status of any 

  
 16 

 
Partner (“Tax Advances”), the General Partner may withhold such amounts and make such tax payments as so required. All Tax Advances made on behalf of a Partner shall be repaid by
reducing the amount of the current or next succeeding distribution or distributions which would otherwise have been made to such Partner or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation
otherwise payable to such Partner. For all purposes of this Agreement such Partner shall be treated as having received the amount of the distribution that is equal to the Tax Advance. Each Partner hereby agrees to indemnify and hold harmless the
Partnership and the other Partners from and against any liability (including, without limitation, any liability for taxes, penalties, additions to tax or interest other than any penalties, additions to tax or interest imposed as a result of the
Partnership’s failure to withhold or make a tax payment on behalf of such Partner which withholding or payment is required pursuant to applicable Law but only to the extent amounts sufficient to pay such taxes were not timely distributed to the
Partner pursuant to Section 4.01(b)) with respect to income attributable to or distributions or other payments to such Partner. 
 Section 5.08. Tax Matters. The General Partner shall be the initial “tax matters partner” within the meaning of Section 6231(a)(7) of the Code (the “Tax Matters
Partner”). The Partnership shall file as a partnership for federal, state, provincial and local income tax purposes, except where otherwise required by Law. All elections required or permitted to be made by the Partnership, and all other
tax decisions and determinations relating to federal, state, provincial or local tax matters of the Partnership, shall be made by the Tax Matters Partner, in consultation with the Partnership’s attorneys and/or accountants. Tax audits,
controversies and litigations shall be conducted under the direction of the Tax Matters Partner. The Tax Matters Partner shall keep the other Partners reasonably informed as to any tax actions, examinations or proceedings relating to the Partnership
and shall submit to the other Partners, for their review and comment, any settlement or compromise offer with respect to any disputed item of income, gain, loss, deduction or credit of the Partnership. As soon as reasonably practicable after the end
of each Fiscal Year, the Partnership shall send to each Partner a copy of United States Internal Revenue Service Schedule K-1, and any comparable statements required by applicable United States state or local income tax Law as a result of the
Partnership’s activities or investments, with respect to such Fiscal Year. The Partnership also shall provide the Partners with such other information as may be reasonably requested for purposes of allowing the Partners to prepare and file
their own tax returns. The Partnership shall use any reasonable method or combination of methods in accordance with Section 706(d) of the Code for the purpose of allocating or specifically allocating items of income, gain, loss, deduction and
expense of the Partnership for federal income tax purposes to account for the varying interests of the Partners for the Fiscal Year. 
 Section 5.09. Other Allocation Provisions. Certain of the foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to
comply with Treasury Regulations Section 1.704-1 (b) and shall be interpreted and applied in a manner consistent with such regulations. Section 5.03, Section 5.04 and Section 5.05 may be amended at any time by the General
Partner if the General Partner believes such amendment is advisable, so long as any such amendment does not materially change the relative economic interests of the Partners. Furthermore, the General Partner shall use its reasonable best efforts to
cause its subsidiaries to make adjustments to Capital Accounts to reflect an adjustment to the carrying value of such subsidiaries assets consistent with the adjustments to Carrying Values of the Partnerships assets hereunder. 

  
 17 

 ARTICLE VI 
 BOOKS AND RECORDS; REPORTS 
 Section 6.01. Books and
Records. 
 (a) At all times during the continuance of the Partnership, the General Partner shall prepare and maintain
separate books of account for the Partnership. 
 (b) Except as limited by Section 6.01(c), each Limited Partner shall have
the right to receive, for a purpose reasonably related to such Limited Partner’s interest as a Limited Partner in the Partnership, upon reasonable written demand stating the purpose of such demand and at such Limited Partner’s own expense:

 (i) a copy of this Agreement and all amendments thereto, together with a copy of the executed copies of all powers of
attorney pursuant to which this Agreement and all amendments thereto have been executed; and 
 (ii) promptly after their
becoming available, copies of the Partnership’s federal, state and local income tax returns and reports, if any, for the three most recent years. 
 (c) The General Partner may keep confidential from the Limited Partners, for such period of time as the General Partner determines in its sole discretion, (i) any information that the General Partner
reasonably believes to be in the nature of trade secrets or (ii) other information the disclosure of which the General Partner believes is not in the best interests of the Partnership, could damage the Partnership or its business or that the
Partnership is required by law or by agreement with any third party to keep confidential. 
 ARTICLE VII 

PARTNERSHIP UNITS 
 Section 7.01. Units. Interests in the Partnership shall be represented by Units. The Units initially are comprised of one Class: Class A Units. The General Partner may establish,
from time to time in accordance with such procedures as the General Partner shall determine from time to time, other Classes, one or more series of any such Classes, or other Partnership securities with such designations, preferences, rights, powers
and duties (which may be senior to existing Classes and series of Units or other Partnership securities), as shall be determined by the General Partner, including (i) the right to share in Profits and Losses or items thereof; (ii) the
right to share in Partnership distributions; (iii) the rights upon dissolution of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may or shall be required to redeem the Units or other Partnership
securities (including sinking fund provisions); (v) whether such Unit or other Partnership security is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi) the terms
and conditions upon which each Unit or other Partnership security will be issued, evidenced by certificates and assigned or transferred; (vii) the method for determining the Percentage Interest as to such Units or other Partnership securities;
and (viii) the right, if any, of the holder of each such Unit or other Partnership security to vote on Partnership matters, including matters relating to the relative 

  
 18 

 
designations, preferences, rights, powers and duties of such Units or other Partnership securities. Except as expressly provided in this Agreement to the contrary, any reference to
“Units” shall include the Class A Units and any other Classes that may be established in accordance with this Agreement. All Units of a particular Class shall have identical rights in all respects as all other Units of such Class,
except in each case as otherwise specified in this Agreement. 
 Section 7.02. Register of Partnership
Interests. The register of partnership interests of the Partnership shall be the definitive record of ownership of each Unit and all relevant information with respect to each Partner. Unless the General Partner shall determine otherwise, Units
shall be uncertificated and recorded in the books and records and the register of partnership interests of the Partnership. 

Section 7.03. Registered Partners. The Partnership shall be entitled to recognize the exclusive right of a Person
registered on its records as the owner of Units for all purposes and shall not be bound to recognize any equitable or other claim to or interest in Units on the part of any other Person, whether or not it shall have express or other notice thereof,
except as otherwise provided by the Act or other applicable Law. 
 ARTICLE VIII 

TRANSFER RESTRICTIONS 
 Section 8.01. Limited Partner Transfers. 
 (a) Except as
provided in clauses (b) and (c) of this Section 8.01, no Limited Partner or Assignee thereof may Transfer (including by exchanging in an Exchange Transaction) all or any portion of its Units or other interest in the Partnership (or
beneficial interest therein) without the prior consent of the General Partner, which consent may be given or withheld, or made subject to such conditions (including, without limitation, the receipt of such legal opinions and other documents that the
General Partner may require) as are determined by the General Partner, in each case in the General Partner’s sole discretion. Any such determination in the General Partner’s discretion in respect of Units shall be final and binding. Such
determinations need not be uniform and may be made selectively among Limited Partners, whether or not such Limited Partners are similarly situated, and shall not constitute the breach of any duty hereunder or otherwise existing at law, in equity or
otherwise. Any purported Transfer of Units that is not in accordance with, or subsequently violates, this Agreement shall be, to the fullest extent permitted by law, null and void. 

(b) Notwithstanding clause (a) above, and subject to Section 8.03, each Limited Partner may exchange or otherwise Transfer
Units in an Exchange Transaction pursuant to the terms of the Exchange Agreement. In the case of a Transfer of Units in connection with an Exchange Transaction, the Percentage Interests of the Limited Partners shall be appropriately adjusted to
provide for, as applicable, a decrease in the number of Units owned by the exchanging Limited Partner and an increase in the number of Units owned by APO Corp. 

  
 19 

 (c) Notwithstanding clause (a) above, and subject to Section 8.04, each Limited
Partner that is a party to a Roll-up Agreement may exchange or otherwise Transfer Units pursuant to the terms and provisions thereof. 
 Section 8.02. Encumbrances. No Limited Partner or Assignee may create an Encumbrance with respect to all or any portion of its Units (or any beneficial interest therein) other than
Encumbrances that run in favor of the Limited Partner unless the General Partner consents in writing thereto, which consent may be given or withheld, or made subject to such conditions as are determined by the General Partner, in the General
Partner’s sole discretion. Consent of the General Partner shall be withheld until the holder of the Encumbrance acknowledges the terms and conditions of this Agreement. Any purported Encumbrance that is not in accordance with this Agreement
shall be, to the fullest extent permitted by law, null and void. 
 Section 8.03. Further Restrictions.
Notwithstanding any contrary provision in this Agreement, in no event may any Transfer of a Unit be made by any Limited Partner or Assignee if: 
 (a) such Transfer is made to any Person who lacks the legal right, power or capacity to own such Unit; 
 (b) such Transfer would require the registration of such transferred Unit or of any Class of Unit pursuant to any applicable United States federal or state securities laws (including, without limitation,
the Securities Act or the Exchange Act) or other non-U.S securities laws (including Canadian provincial or territorial securities laws) or would constitute a non-exempt distribution pursuant to applicable provincial or state securities laws;

 (c) such Transfer would cause (i) all or any portion of the assets of the Partnership to (A) constitute “plan
assets” (under ERISA, the Code or any applicable Similar Law) of any existing or contemplated Limited Partner, or (B) be subject to the provisions of ERISA, Section 4975 of the Code or any applicable Similar Law, or (ii) the
General Partner to become a fiduciary with respect to any existing or contemplated Limited Partner, pursuant to ERISA, any applicable Similar Law, or otherwise; 
 (d) to the extent requested by the General Partner, the Partnership does not receive such legal and/or tax opinions and written instruments (including, without limitation, copies of any instruments of
Transfer and such Assignee’s consent to be bound by this Agreement as an Assignee) that are in a form satisfactory to the General Partner, as determined in the General Partner’s sole discretion; or 

(e) such Transfer would create a substantial risk that the Partnership would be classified or otherwise treated other than as a
partnership for United States federal income tax purposes. 
 Section 8.04. Rights of Assignees. Subject to
Section 8.05 and Section 8.06, the transferee of any permitted Transfer pursuant to this Article VIII will be an assignee only (“Assignee”), and only will receive, to the extent transferred, the distributions and
allocations of income; gain, loss, deduction, credit or similar item to which the Partner which transferred its 

  
 20 

 
Units would be entitled, and such Assignee will not be entitled or enabled to exercise any other rights or powers of a Partner, such other rights, and all obligations relating to, or in
connection with, such interest remaining with the transferring Partner. The transferring Partner will remain a Partner even if it has transferred all of its Units to one or more Assignees until such time as the Assignee(s) is admitted to the
Partnership as a Partner pursuant to Section 8.05 or Section 8.06. 
 Section 8.05. Admissions,
Withdrawals and Removals. 
 (a) No Person may be admitted to the Partnership as an additional General Partner or substitute
General Partner without the prior written consent or ratification of APO Corp. A General Partner will not be entitled to Transfer all of its Units or to withdraw from being a General Partner of the Partnership unless another General Partner shall
have been admitted hereunder (and not have previously been removed or withdrawn). 
 (b) No Limited Partner will be removed or
entitled to withdraw from being a Partner of the Partnership except in accordance with Section 8.07. 
 (c) Except as
otherwise provided in Article IX or the Act, no admission, substitution, withdrawal or removal of a Partner will cause the dissolution of the Partnership. To the fullest extent permitted by law, any purported admission, withdrawal or removal that is
not in accordance with this Agreement shall be null and void. 
 Section 8.06. Admission of Assignees as
Substitute Limited Partners. An Assignee will become a substitute Limited Partner only if and when each of the following conditions is satisfied: 
 (a) the General Partner consents in writing to such admission, which consent may be given or withheld, or made subject to such conditions as are determined by the General Partner, in each case in the
General Partner’s sole discretion; 
 (b) if required by the General Partner, the General Partner receives written
instruments (including, without limitation, copies of any instruments of Transfer and such Assignee’s consent to be bound by this Agreement as a substitute Limited Partner) that are in a form satisfactory to the General Partner (as determined
in its sole discretion); 
 (c) if required by the General Partner, the General Partner receives an opinion of counsel
satisfactory to the General Partner to the effect that such Transfer is in compliance with this Agreement and all applicable Law; and 
 (d) if required by the General Partner, the parties to the Transfer, or any one of them, pays all of the Partnership’s reasonable expenses connected with such Transfer (including, but not limited to,
the reasonable legal and accounting fees of the Partnership). 
 Section 8.07. Withdrawal and Removal of Limited
Partners. If a Limited Partner ceases to hold any Units, then such Limited Partner shall withdraw from the Partnership and shall cease to be a Limited Partner and to have the power to exercise any rights or powers of a Limited Partner.

 ARTICLE IX 
 WINDING UP AND DISSOLUTION 
 Section 9.01. No
Dissolution. Except as required by the Act, the Partnership shall not be dissolved by the admission of additional Partners or withdrawal of Partners in accordance with the terms of this Agreement. The Partnership may be wound up and dissolved
only pursuant to the provisions of this Article IX, and the Partners hereby irrevocably waive any and all other rights they may have to cause a winding up and dissolution of the Partnership or a sale or partition of any or all of the Partnership
assets. 
 Section 9.02. Events Causing Dissolution. The affairs of the Partnership shall be wound up and the
Partnership subsequently dissolved upon the occurrence of any of the following events: 
 (a) the making of orders or directions
for the winding up of the Partnership by a court under Section 15(4) of the Act; 
 (b) any event which makes it unlawful
for the business of the Partnership to be carried on by the Partners; 
 (c) the written consent of the General Partner and APO
Corp.; 
 (d) any other event not inconsistent with any provision hereof causing a dissolution of the Partnership under the Act;

 (e) the Incapacity or removal of the General Partner or the occurrence of a Disabling Event with respect to the General
Partner; provided that the Partnership will not be dissolved or required to be wound up in connection with any of the events specified in this Section 9.02(e) if: (i) at the time of the occurrence of such event there is at least one
other general partner of the Partnership who is hereby authorized to, and elects to, carry on the business of the Partnership; or (ii) APO Corp. consents to or ratifies the continuation of the business of the Partnership and the appointment of
another general partner of the Partnership, effective as of the event that caused the General Partner to cease to be a general partner of the Partnership, within 120 days following the occurrence of any such event. 

Sections 15(2), 15(5), 15(6) and 15(7) of the Act shall not apply to the Partnership. 

Section 9.03. Distribution upon Dissolution. Upon the occurrence of an event under section 9.02 causing the winding up
of the Partnership, the Partnership shall not be terminated and shall continue until the winding up of the affairs of the Partnership is completed. Upon the winding up of the Partnership, the General Partner, or any other Person designated by the
General Partner (the “Liquidation Agent”), shall take full account of the assets and liabilities of the Partnership and shall, unless the General Partner determines otherwise, liquidate the assets of the Partnership as promptly as
is consistent with obtaining the fair value thereof. The proceeds of any liquidation shall be applied and distributed in the following order: 

  
 22 

 (a) First, to the satisfaction of debts and liabilities of the Partnership (including
satisfaction of all indebtedness to Partners and/or their Affiliates to the extent otherwise permitted by law) including the expenses of liquidation, and including the establishment of any reserve which the Liquidation Agent shall deem reasonably
necessary for any contingent, conditional or unmatured contractual liabilities or obligations of the Partnership (“Contingencies”). Any such reserve may be paid over by the Liquidation Agent to any attorney- at-law, or acceptable
party, as escrow agent, to be held for disbursement in payment of any Contingencies and, at the expiration of such period as shall be deemed advisable by the Liquidation Agent for distribution of the balance in the manner hereinafter provided in
this Section 9.03; 
 (b) Second, pro rata based on the maximum amounts distributable under clauses (i) and
(ii) of this Section 9.03(b), (i) to APO Corp., the Undistributed Special Allocation Amount and (ii) to AP Professional, the aggregate amount allocated to AP Professional pursuant to Section 5.05(j), until APO Corp. has
received distributions pursuant to this Section 9.03(b) of the Undistributed Special Allocation Amount and AP Professional has received distributions pursuant to this Section 9.03(b) of the aggregate amount allocated to it pursuant to
Section 5.05(j); and 
 (c) The balance, if any, to the Partners, pro rata to each of the Partners in accordance with their
Percentage Interests. 
 Section 9.04. Time for Liquidation. A reasonable amount of time shall be allowed for
the orderly liquidation of the assets of the Partnership and the discharge of liabilities to creditors so as to enable the Liquidation Agent to minimize the losses attendant upon such liquidation. 

Section 9.05. Dissolution. The Partnership shall dissolve when (i) all of the assets of the Partnership, after
payment of or due provision for all debts, liabilities and obligations of the Partnership, shall have been distributed to the holders of Units in the manner provided for in this Article IX, and (ii) a notice of dissolution shall have been filed
by the General Partner or Liquidation Agent with the Registrar of Exempted Limited Partnerships in the Cayman Islands pursuant to Section 15(3) of the Act. 
 Section 9.06. Claims of the Partners. The Partners shall look solely to the Partnership’s assets for the return of their Capital Contributions, and if the assets of the Partnership
remaining after payment of or due provision for all debts, liabilities and obligations of the Partnership are insufficient to return such Capital Contributions, the Partners shall have no recourse against the Partnership or any other Partner or any
other Person. No Partner with a negative balance in such Partner’s Capital Account shall have any obligation to the Partnership or to the other Partners or to any creditor or other Person to restore such negative balance during the existence of
the Partnership, upon termination and dissolution of the Partnership or otherwise, except to the extent required by the Act. 

Section 9.07. Survival of Certain Provisions. Notwithstanding anything to the contrary in this Agreement, the
provisions of Section 10.02 and Section 11.09 shall survive the termination and dissolution of the Partnership. 

  
 23 

 ARTICLE X 
 LIABILITY AND INDEMNIFICATION 
 Section 10.01. Liability of
Partners. 
 (a) No Limited Partner shall be liable for any debt, obligation or liability of the Partnership or of any other
Partner or have any obligation to restore any deficit balance in its Capital Account solely by reason of being a Partner of the Partnership, except to the extent required by the Act. 

(b) To the fullest extent permitted by law and except as required by law, this Agreement is not intended to, and does not, create or
impose any fiduciary duty on any of the Partners (including, without limitation, the General Partner) hereto or on their respective Affiliates. Further, the Partners hereby eliminated, to the fullest extent permitted by law, any and all fiduciary
duties that, absent such elimination, may exist at or be implied by Law or in equity, and in doing so, recognize, acknowledge and agree that their duties and obligations to one another and to the Partnership are only as expressly set forth in this
Agreement and those required by the Act. 
 (c) To the fullest extent permitted by law and to the extent that, at law or in
equity, any Partner has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to another Partner, the Partners acting under this Agreement will not be liable to the Partnership or to any such other Partner for
their good faith reliance on the provisions of this Agreement. To the fullest extent permitted by law, the provisions of this Agreement, to the extent that they restrict or eliminate the duties and liabilities relating thereto of any Partner
otherwise existing at law or in equity to the Partnership or the Partners, are agreed by the Partners to replace or eliminate to that extent such other duties and liabilities of the Partners relating thereto. 

(d) The General Partner may consult with legal counsel, accountants and financial or other advisors and any act or omission suffered or
taken by the General Partner on behalf of the Partnership or in furtherance of the interests of the Partnership in good faith in reliance upon and in accordance with the advice of such counsel, accountants or financial or other advisors will, with
respect to the Partnership and the other Partners, be full justification for any such act or omission, and to the fullest extent permitted by law, the General Partner will be fully protected from liability to the Partnership and the other Partners
in so acting or omitting to act so long as such counsel or accountants or financial or other advisors were selected with reasonable care. 
 (e) To the fullest extent permitted by law and notwithstanding any other provision of this Agreement or any agreement contemplated herein or otherwise applicable provision of law or equity, whenever in
this Agreement the General Partner is permitted or required to make a decision in its “sole discretion” or “discretion” or under a grant of similar authority or latitude, such General Partner shall be entitled to consider only
such interests and factors as it desires, including its own interests, and shall have no duty or obligation to give any consideration to any interest of or factors affecting the Limited Partners; provided that the General Partner shall act at
all times in good faith in the interests of the Partnership pursuant to the Act. 

  
 24 

 Section 10.02. Indemnification. 

(a) To the fullest extent permitted by law, the General Partner (including, without limitation, for this purpose each former and present
director, officer, consultant, advisor, manager, member, partner, employee and stockholder of the General Partner) and each Limited Partner (including any former Limited Partner), in his, her or its capacity, as such, and to the extent such Limited
Partner participates, directly or indirectly, in the Partnership’s activities (each, a “Covered Person” and, collectively, the “Covered Persons”) shall not be liable to the Partnership or, to the extent
applicable, to any of the other Partners for any loss, claim, damage or liability occasioned by any acts or omissions in the performance of his, her or its services hereunder, unless it shall ultimately be determined by final judicial decision from
which there is no further right to appeal (a “Final Adjudication”) that such loss, claim, damage or liability is due to an act or omission of a Covered Person (i) made in bad faith or with criminal intent or (ii) that
materially adversely affected the Partnership and that failed to satisfy the duty of care owed pursuant to the Partnership (as modified by this Agreement). 
 (b) A Covered Person shall be indemnified to the fullest extent permitted by law by the Partnership against any losses, claims, damages, liabilities, and expenses (including attorneys’ fees,
judgments, fines, penalties and amounts paid in settlement) incurred by or imposed upon him by reason of or in connection with any action taken or omitted by such Covered Person arising out of the Covered Person’s status as a Partner or his,
her or its activities on behalf of the Partnership, including in connection with any action, suit, investigation or proceeding before any judicial, administrative, regulatory or legislative body or agency to which he, she or it may be made a party
or otherwise involved or with which he, she or it has been threatened by reason of being or having been the General Partner or by reason of serving or having served as a director, officer, consultant, advisor, manager, member, partner, employee or
stockholder of any enterprise in which the Partnership or any of its Affiliates has or had a financial interest; provided that the Partnership may, but shall not be required to, indemnify a Covered Person with respect to any matter as to
which there has been a Final Adjudication that his, her or its acts or his, her or its failure to act (i) were in bad faith or with criminal intent, or (ii) were of a nature that makes indemnification by the relevant Affiliate unavailable.
The right to indemnification granted by this Section 10.02 shall be in addition to any rights to which a Covered Person may otherwise be entitled and shall inure to the benefit of his, her or its successors by operation of law or valid assigns
of such Covered Person. The Partnership shall pay the expenses incurred by a Covered Person in defending a civil or criminal action, suit, investigation or proceeding in advance of the final disposition of such, action, suit, investigation or
proceeding, upon receipt of an undertaking by the Covered Person to repay such payment if there shall be a Final Adjudication that he, she or it is not entitled to indemnification as provided herein. In any suit brought by the Covered Person to
enforce a right to indemnification hereunder it shall be a defense that the Covered Person has not met the applicable standard of conduct set forth in this Section 10.02, and in any suit in the name of the Partnership to recover expenses
advanced pursuant to the terms of an undertaking the Partnership shall be entitled to recover such expenses upon Final Adjudication that the Covered Person has not met the applicable standard of conduct set forth in this Section 10.02. In any
such suit brought to enforce 

  
 25 

 
a right to indemnification or to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the Covered Person is not entitled to be indemnified, or to
an advancement of expenses, shall be on the Partnership (or any Limited Partner acting derivatively or otherwise on behalf of the Partnership or the Limited Partners). The General Partner may not satisfy any right of indemnity or reimbursement
granted in this Section 10.02 or to which it may be otherwise entitled except out of the assets of the Partnership (including, without limitation, insurance proceeds and rights pursuant to indemnification agreements), and no Partner shall be
personally liable with respect to any such claim for indemnity or reimbursement. The General Partner may enter into appropriate indemnification agreements and/or arrangements in favor of any Covered Person reflective of the provisions of this
Section 10.02 and obtain appropriate insurance coverage on behalf and at the expense of the Partnership to secure the Partnership’s indemnification obligations hereunder. To the fullest extent permitted by law, each Covered Person shall be
deemed a third party beneficiary (to the extent not a direct party hereto) to this Agreement and, in particular, the provisions of this Section 10.02. 
 (c) To the fullest extent permitted by law and to the extent that, at law or in equity, a Covered Person has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or the
Partners, the Covered Person shall not be liable to the Partnership or to any Partner for its good faith reliance on the provisions of this Agreement. To the fullest extent permitted by law, the provisions of this Agreement, to the extent that they
restrict or eliminate the duties and liabilities of a Covered Person otherwise existing at law or in equity to the Partnership or the Partners, are agreed by the Partners to replace or eliminate such other duties and liabilities of each such Covered
Person.
