GENERAL RELEASE, SEPARATION AND SETTLEMENT AGREEMENT

THIS AGREEMENT (“Agreement”) is made this 19th day of August, 2009 (the “Effective Date”) by and between Tim Sullivan (“Employee”) and Internap Network Services Corporation (“INTERNAP”), and arises out of the termination of Employee’s
employment.

 

WHEREAS, INTERNAP has determined that it is in the best interests of INTERNAP to end Employee’s employment as set forth herein; and

 

WHEREAS, Employee and INTERNAP agree that Employee’s employment with INTERNAP is terminated effective July 31, 2009 (“Termination Date”);

 

NOW, THEREFORE, for and in consideration of the foregoing, the mutual promises and covenants set forth herein, and for other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, Employee and INTERNAP, intending to be legally bound, agree as follows:

 

1.             The foregoing recitals are hereby made a part of this Agreement and are incorporated herein by reference.

 

2.             (a)           Employee’s employment with INTERNAP will be terminated effective on the Termination Date.

 

(b)           Employee acknowledges and agrees that with payment of normal payroll through the Termination Date, he will have received all compensation (whether as deferred compensation, bonuses, or otherwise), employment
benefits (including, but not limited to, health insurance, dental insurance, life insurance, disability insurance, 403(b) contributions, and profit-sharing payments), vacation pay, sick pay, other paid leave, and any other alleged obligations relating to Employee’s employment with INTERNAP through the Termination Date.

 

(c)           As consideration for Employee’s service to INTERNAP and for the promises made by Employee in this Agreement, INTERNAP agrees to pay to Employee the sum of Two Hundred Seventy-Five Thousand Dollars ($275,000.00).  The
parties agree that this payment will be made to Employee in twelve (12) equal monthly installments of Twenty-Two Thousand Nine Hundred Sixteen Dollars and sixty-six cents ($22,916.66) less all lawful withholdings, beginning on the first regular payroll date following the expiration of the seven (7) day revocation period set forth in Paragraph 5(b) of this Agreement, provided that Employee does not revoke the Agreement within that time period.  Additionally, Employee may elect to continue at his expense,
health insurance coverage under INTERNAP’s healthcare coverage plan commencing on the Termination Date and continuing thereafter for a period of eighteen (18) months, pursuant to Title X of the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA).  Employee shall remit to INTERNAP payment in full for such health insurance coverage on a monthly basis, in advance.  Employee may, at his written election, convert any life insurance coverage obtained through INTERNAP to an individual
plan in accordance with the terms of such coverage.

(d)           Employee understands and agrees that the payments and covenants by INTERNAP referenced in Paragraph 2 are in consideration for his promises in this Agreement and that he otherwise is not entitled to this
or any other payment for any reason on account of his separation from employment with INTERNAP.  The parties further understand and agree that the payment and promises referenced in Paragraph 2 shall fully and completely extinguish all obligations of INTERNAP to Employee, including, but not limited to, severance pay, compensation (whether as deferred compensation, bonuses, or otherwise), the provision of any employment benefits (including, but not limited to, health insurance, dental insurance, life
insurance, disability insurance, 403(b) contributions, and profit-sharing payments), vacation pay, sick pay, or any other alleged obligations relating to Employee’s employment with INTERNAP whether such amounts are claimed under contract, INTERNAP’s Employment Security Plan or otherwise.

 

(e)           Employee agrees that all unvested INTERNAP equity shall expire on the Termination Date.

 

3.             Employee acknowledges INTERNAP is relying on Employee’s compliance with the terms of the Covenants Agreement attached hereto as Schedule A.

 

4.             (a)            In consideration of the foregoing payments and covenants, Employee, for himself and for his heirs, legal representatives,
and assigns, hereby unconditionally and absolutely releases, remises, acquits and forever discharges INTERNAP and its heirs, executors, administrators, legal and personal representatives; former and/or current owners, partners, officers, directors, employees, residents, shareholders, managers, agents, attorneys, predecessors, successors, assigns, trustees, purchasers, principals, and privies; past, present, and future parent, subsidiary, and affiliated companies (both direct and indirect), divisions, related

(b)           Employee agrees never to file a lawsuit, claim, or cause of action seeking damages, reinstatement, attorney fees or other personal relief against INTERNAP and/or the INTERNAP Releasees based on the claims being released by his in this Agreement.  Notwithstanding
this waiver of remedies, above, nothing in this Agreement shall be construed to prohibit Employee from (1) filing a charge with the Equal Employment Opportunity Commission or (2) participating in any investigation or proceeding conducted by the Equal Employment Opportunity Commission, or (3) filing any charge or claim – including Worker’s Compensation claims – not waiveable by law.

 

5.            Employee knowingly relinquishes, waives and forever releases any and all claims or personal remedies arising under the Age Discrimination in Employment Act, 29 U.S.C.§ 621, et
seq., related in any manner to his employment with INTERNAP or his separation from such employment.  In making this release:

 

(a)           Employee acknowledges that he has forty-five (45) days to review this Agreement prior to signing it.  To the extent that Employee has decided to execute this Agreement prior to the expiration
of the forty-five (45) day period, he acknowledges that he has voluntarily executed the Election attached to this Agreement as Exhibit 1.

 

(b)           Employee understands that he has a period of seven (7) days after signing this Agreement to revoke it and not receive the monetary payments provided to his under the terms of this Agreement.

 

(c)           Employee further understands that this Paragraph 5, pertaining specifically to claims or rights arising under the Age Discrimination in Employment Act, does not cover any rights, claims, or remedies, if
any, that may arise after the date on which this Agreement is executed, and does not affect his right to challenge the validity of this release under the law.

 

(d)           Employee acknowledges and agrees that the payments and other consideration made by INTERNAP under Paragraph 2 of this Agreement are in addition to anything of value to which Employee is already entitled.

 

6.            (a)           Employee agrees to fully cooperate with reasonable requests by INTERNAP regarding any and all matters associated with any investigations,
claims or litigation involving INTERNAP about which the Employee has knowledge or the ability to assist INTERNAP in its defense of such investigations, claims or litigation.  Employee’s cooperation in such matters will include answering questions by INTERNAP regarding the subject of any such investigations, claims, or litigation, voluntarily participating in depositions, providing affidavits and testimony if necessary, and assisting INTERNAP in responding to data or discovery requests.  Employee
agrees that any participation in the above-referenced matters will be truthful and factual.  Employee will be compensated at the rate of $150 per hour for his time associated with his participation in the matters.  INTERNAP will reimburse Employee for all pre-approved reasonable out of pocket expenses incurred in providing such cooperation.

whatsoever against INTERNAP.  INTERNAP specifically disclaims any liability to or wrongful acts against Employee or any other person.

 

8.            From and after the Effective Date of this Agreement, Employee will not provide any disparaging information about INTERNAP or any of its current or former parties, officers, directors, agents, employees,

by applicable law.

 

9.            Employee represents that he has returned to INTERNAP any property of INTERNAP, including, but not limited to, computers, software, data, keys, identification cards, access cards, credit cards, telephone

10.           Any other benefits not mentioned in this Agreement that Employee may be entitled to, including, but not limited to, his rights to health insurance continuation under Georgia law, shall be provided to Employee
in accordance with the underlying plan or document governing such benefits and/or applicable law.

 

11.           (a)           Employee acknowledges and agrees that, before signing this Agreement, he was advised and is hereby advised in writing by INTERNAP to
review it and consult with an attorney of his choosing and that, to the extent Employee desired he has availed himself of these opportunities.

 

(b)          Employee represents and agrees that he has carefully read and fully understands all of the provisions of this Agreement.  Employee understands the final and binding nature of the release and waiver of his rights specified herein, and he knowingly and voluntarily enters

EXHIBIT 2

 

AFFIDAVIT OF TIM SULLIVAN

 

I, Tim Sullivan, having been duly sworn by the undersigned notary public, do hereby depose and state that:

 

1.             I am of the age of majority, I suffer no legal disabilities and am giving this Affidavit based upon my own personal knowledge and I am competent to testify to the same.

2.             I was continuously employed by Internap Network Services Corporation ("Internap") from November 1, 2006 until the termination of my employment from Internap.  I was its Chief Technology Officer at the time of my termination from Internap.

3.             I am aware that on November 12, 2008, a putative securities fraud class action lawsuit was filed against Internap and its Chief Executive Officer, James P. DeBlasio, in the United States District Court for the Northern District of Georgia, captioned Catherine
Anastasio and Stephen Anastasio v. Internap Network Services Corp. and James P. DeBlasio, Civil Action No. 1:08-CV-3462-JOF (“Anastasio Litigation”). I am further aware that the complaint alleges that Internap and the individual defendant violated Section 10(b) of the Exchange Act, and that the individual defendant also violated Section 20(a) of the Exchange Act as a “control person” of Internap. Plaintiffs purport to bring these claims on behalf of a class of Internap investors
who purchased its stock between March 28, 2007 and March 18, 2008.  Plaintiffs allege generally that, during the putative class period, Internap made misleading statements and omitted material information regarding (1) integration of VitalStream, (2) customer issues and related credits due to services outages, and (3) Internap’s previously reported 2007 revenue that Internap subsequently reduced in 2008 as announced on March 18, 2008. Plaintiffs assert that Internap and the individual defendant
made these misstatements and omissions in order to keep Internap’s stock price high. Plaintiffs seek unspecified damages and other relief.  I am not aware of any information or facts that substantiate plaintiff’s claims or assertions in the Anastasio Litigation.  Further, I certify that I have provided to Internap’s external counsel all data, information, and materials about or relating to the Anastasio litigation and the matters alleged therein.

4.             I am not aware of any transaction, event, or practice concerning Internap that I considered to be improper, illegal, that constituted a violation of Federal or state rule or regulation, or that otherwise raised corporate governance issues to me.

5.             I swear under penalty of perjury that I am aware of no legal or equitable cause of action I may have against Internap that is not released in the Release and

Settlement Agreement dated August 19th, 2009.

6.             Further Affiant sayeth naught.

(a)
	
Internap would suffer irreparable harm;

	 	 	 
	  	
(b)
	
it would be difficult to determine damages, and money damages alone would be an inadequate remedy for the injuries suffered by Internap;  and

	 	 	 
	  	
(c)
	
if Internap seeks injunctive relief to enforce this Agreement, You shall waive and shall not (i) assert any defense that Internap has an adequate remedy at law with respect to the breach, (ii) require that Internap submit proof of the economic value of any Trade Secret or Confidential Information, or (iii) require Internap to post a bond
or any other security.

 

Nothing contained in this Agreement shall limit Internap’s right to any other remedies at law or in equity.

 

9.            Independent Enforcement.  Each of the covenants set forth in Sections 2 – 7 of this Agreement shall be construed as an agreement independent of (i) each of the other covenants set forth in
Sections 2 – 7, (ii) any other agreements, or (iii) any other provision in this Agreement, and the existence of any claim or cause of action by You against Internap, whether predicated on this Agreement or otherwise, regardless of who was at fault and regardless of any claims that either You or Internap may have against the other, shall not constitute a defense to the enforcement by Internap of any of the covenants set forth in Sections 2 – 7 of this Agreement.  Internap shall not be barred
from enforcing any of the covenants set forth in Sections 2 – 7 of this Agreement by reason of any breach of (i) any other covenant set forth in Sections 2 – 7 of this Agreement, (ii) any other part of this Agreement, or (iii) any other agreement with You.

10.           Waiver.  Internap’s failure to enforce any provision of this Agreement shall not act as a waiver of that or any other provision.  Internap’s waiver of any breach of this Agreement
shall not act as a waiver of any other breach.

 

11.           Severability.  The provisions of this Agreement are severable. If any provision is determined to be invalid, illegal, or unenforceable, in whole or in part, the remaining provisions and any partially
enforceable provisions shall remain in full force and effect.

 

12.           Governing Law.  The laws of the State of Georgia shall govern this Agreement.  If Georgia’s conflict of law rules would apply another state’s laws, the Parties agree that Georgia
law shall still govern.

 

13.           No Strict Construction.  If there is a dispute about the language of this Agreement, the fact that one Party drafted the Agreement shall not be used in its interpretation.

 

14.           Entire Agreement.  This Agreement supersedes any prior communications, agreements or understandings, whether oral or written, between the Parties relating to the subject matter of this Agreement.

 

15.           Successors and Assigns.  This Agreement shall be assignable to, and shall inure to the benefit of, Internap’s successors and assigns, including, without limitation, successors through merger,
name change, consolidation, or sale of a majority of Internap’s stock or assets, and shall be binding upon You.  You shall not have the right to assign Your rights or obligations under this Agreement. The covenants contained in this Agreement shall survive cessation of Your employment with Internap, regardless of who causes the cessation or the reason for the cessation.

 

16.           Consent to Jurisdiction and Venue.  You agree that any and all claims arising out of or relating to this Agreement shall be brought in a state or federal court of competent jurisdiction in Georgia.
You consent to the personal jurisdiction of the state and/or federal courts located in Georgia. You waive (a) any objection to jurisdiction or venue, or (b) any defense claiming lack of jurisdiction or improper venue, in any action brought in such courts.

 

17.           Execution.  This Agreement may be executed in one or more counterparts, including, but not limited to, facsimiles. Each counterpart shall for all purposes be deemed to be an original, and each counterpart
shall constitute this Agreement.

 

18.           Affirmation.  You acknowledge that You have carefully read this Agreement, You know and understand its terms and conditions, and You have had the opportunity to ask Internap any questions You may
have had prior to signing this Agreement.

 SECTION 1.04. Accounting Terms; GAAP. Except as otherwise expressly provided herein, all terms of
an accounting or financial nature shall be construed in accordance with GAAP, as in effect from time to time, provided that, if the Borrower notifies the Administrative Agent that the Borrower requests an amendment to any provision (including
any definition) hereof to eliminate the effect of any change occurring after the date hereof in GAAP or in the application thereof on the operation of such provision (or if the Administrative Agent notifies the Borrower that the Required Lenders
request an amendment to any provision hereof for such purpose), regardless of whether any such notice is given before or after such change in GAAP or in the application thereof, then such provision shall be interpreted on the basis of GAAP as in
effect and applied immediately before such change shall have become effective until such notice shall have been withdrawn or such provision amended in accordance herewith. 
 SECTION 1.05. Pro Forma Calculations (a) Notwithstanding anything to the contrary herein, the Consolidated Interest Coverage Ratio, the
Consolidated Net Debt Ratio, the Consolidated Net Secured Debt Ratio and the Leverage Ratio shall be calculated in the manner prescribed by this Section 1.05. 
 (b) In the event that since the beginning of the most recent four consecutive fiscal quarters for which internal financial statements of
the Borrower are then available the Borrower or any Subsidiary since the beginning of such period has Incurred any Indebtedness that remains outstanding or Repaid any Indebtedness, or the transaction giving rise to the need to calculate the
Consolidated Interest Coverage Ratio, Consolidated Net Debt Ratio, Consolidated Net Secured Debt Ratio or the Leverage Ratio is an Incurrence or Repayment of Indebtedness, Consolidated Interest Expense, Total Indebtedness and Consolidated EBITDA for
such period shall be calculated after giving effect on a pro forma basis to such Incurrence or Repayment as if such Indebtedness was Incurred or Repaid on the first day of such period, provided that, in the event of any such Repayment of
Indebtedness, Consolidated EBITDA for such period shall be calculated as if the Borrower or such Subsidiary had not earned any interest income actually earned during such period in respect of the funds used to Repay such Indebtedness. 
 (c) In the event that since the beginning of the most recent four consecutive fiscal quarters for which internal financial statements of
the Borrower are then available (1) a Specified Transaction has occurred, (2) the transaction giving rise to the need to calculate the Consolidated Interest Coverage Ratio, Consolidated Net Debt Ratio, Consolidated Net Secured Debt Ratio
or the Leverage Ratio is such a Specified Transaction, or (3) since the beginning of such period any Person (that subsequently became a Subsidiary or was merged with or into the Borrower or any Subsidiary since the beginning of such period)
shall have made such a Specified Transaction, Consolidated EBITDA for such period shall be calculated after giving pro forma effect to such Specified Transactions as if such Specified Transactions occurred on the first day of such period.

  

 -38- 

 (d) If any Indebtedness bears a floating rate of interest and is being given pro forma
effect, the interest expense on such Indebtedness shall be calculated as if the base interest rate in effect for such floating rate of interest on the date of determination had been the applicable base interest rate for the entire period (taking
into account any Swap Agreement applicable to such Indebtedness if such Swap Agreement has a remaining term in excess of 12 months). In the event the Equity Interests of any Subsidiary is sold during the period, the Borrower shall be deemed, for
purposes of clause (b) above, to have Repaid during such period the Indebtedness of such Subsidiary to the extent the Borrower and its continuing Subsidiaries are no longer liable for such Indebtedness after such sale. 
 (e) Whenever pro forma effect is to be given to a Specified Transaction, the pro forma calculations shall be performed in accordance with
Article XI of Regulation S-X promulgated under the Securities Act, as interpreted in good faith by the chief financial officer of the Borrower after consultation with the independent certified public accountants of the Borrower, except that any such
pro forma calculation may include operating expense reductions for such period attributable to the transaction to which pro forma effect is being given (including, without limitation, operating expense reductions attributable to execution or
termination of any contract, reduction of costs related to administrative functions, the termination of any employees or the closing (or the approval by the Board of Directors of the closing) of any facility) that have been realized or for which all
steps necessary for the realization of which have been taken or (except in calculating the Leverage Ratio) are reasonably expected to be taken within six months following such transaction, provided, that such adjustments are set forth in an
officers’ certificate which states (i) the amount of such adjustment or adjustments and (ii) that such adjustment or adjustments are based on the reasonable good faith beliefs of the Financial Officer executing such officers’
certificate. 
 (f) Notwithstanding anything to the contrary herein, when calculating the Leverage Ratio solely for the
purposes of Section 6.12 (as opposed to any test of the Leverage Ratio as a condition or qualification to any permitted activity), the events described in this Section 1.05 that occurred subsequent to the end of the most recent four
consecutive fiscal quarters shall not be given pro forma effect. 
 ARTICLE II 
 The Credits 
 SECTION 2.01. Commitments. Subject to the terms and
conditions set forth herein, each Lender agrees to make Revolving Loans to the Borrower from time to time during the Availability Period in an aggregate principal amount that will not result in such Lender’s Exposure exceeding such
Lender’s Commitment. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Revolving Loans. 
 SECTION 2.02. Loans and Borrowings. (a) Each Loan (other than a Swingline Loan) shall be made as part of a Borrowing consisting of Loans of
the same Type made by the 

  

 -39- 

 
Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any
other Lender of its obligations hereunder, provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required. 
 (b) Subject to Section 2.14, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request
in accordance herewith, provided that all Borrowings made on the Effective Date must be made as ABR Borrowings. Each Swingline Loan shall be an ABR Loan. Each Lender at its option may make any Eurodollar Loan by causing any domestic or
foreign branch or Affiliate of such Lender to make such Loan, provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. 
 (c) At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an
integral multiple of $500,000 and not less than $2,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $500,000 and not less than $1,000,000. Borrowings of more than
one Type may be outstanding at the same time. There shall not at any time be more than a total of 10 Eurodollar Borrowings outstanding. Notwithstanding anything to the contrary herein, an ABR Borrowing or Swingline Loan may be in an aggregate amount
(i) that is equal to the entire unused balance of the aggregate Commitments or (ii) that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.05(e). 
 (d) Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or
continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date. 
 SECTION 2.03. Requests
for Borrowings. To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 2:00 pm, New York City time, three Business Days before
the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 2:00 pm, New York City time, one Business Day before the date of the proposed Borrowing, provided that any such notice of an ABR Borrowing to
finance the reimbursement of an LC Disbursement as contemplated by Section 2.05(e) may be given not later than 10:00 a.m., New York City time, on the date of the proposed Borrowing. Each such telephonic Borrowing Request shall be
irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request signed by the Borrower. Each such telephonic and written Borrowing Request shall specify the following information in
compliance with Section 2.02: 
 (i) the aggregate amount of such Borrowing; 
 (ii) the date of such Borrowing, which shall be a Business Day; 
  

 -40- 

 (iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

 (iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period
contemplated by the definition of the term “Interest Period”; and 
 (v) the location and number of the
Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.06. 
 If no election as to the Type
of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one
month’s duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the
requested Borrowing. 
 SECTION 2.04. Swingline Loans. (a) Subject to the terms and conditions set forth herein, the Swingline
Lender agrees to make Swingline Loans to the Borrower from time to time during the Availability Period, in an aggregate principal amount at any time outstanding that will not result in (i) the aggregate principal amount of outstanding Swingline
Loans exceeding $10,000,000 or (ii) the Aggregate Exposures exceeding the aggregate Commitments, provided that the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. Within the
foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Swingline Loans, provided that such Borrowings should be in an aggregate amount that is an integral multiple of $100,000
and not less than $500,000. 
 (b) To request a Swingline Loan, the Borrower shall notify the Administrative Agent of such
request by telephone (confirmed by telecopy), not later than 2:00 p.m., New York City time, on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested date (which shall be a Business Day)
and the amount of the requested Swingline Loan. The Administrative Agent will promptly advise the Swingline Lender of any such notice received from the Borrower. The Swingline Lender shall make each Swingline Loan available to the Borrower by means
of a credit to the general deposit account of the Borrower maintained with the Swingline Lender (or, in the case of a Swingline Loan made to finance the reimbursement of an LC Disbursement as provided in Section 2.05(e), by remittance to
the Issuing Bank) by 3:00 p.m., New York City time, on the requested date of such Swingline Loan. 
 (c) The
Swingline Lender may by written notice given to the Administrative Agent not later than 12:00 noon, New York City time, on any Business Day require the Lenders to acquire participations on such Business Day in all or a portion of the
Swingline Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which Lenders will participate. Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each Lender, 

  

 -41- 

 
specifying in such notice such Lender’s Applicable Percentage of such Swingline Loan or Swingline Loans. Each Lender hereby absolutely and
unconditionally agrees, upon receipt of notice as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such Lender’s Applicable Percentage of such Swingline Loan or Swingline Loans. Each Lender
acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a
Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Lender shall comply with its obligation under this paragraph by wire transfer
of immediately available funds, in the same manner as provided in Section 2.06 with respect to Loans made by such Lender (and Section 2.06 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the
Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Lenders. The Administrative Agent shall notify the Borrower of any participations in any Swingline Loan acquired pursuant to this paragraph, and
thereafter payments in respect of such Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the Borrower (or other party on behalf of the Borrower) in respect of
a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be promptly remitted by
the Administrative Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear, provided that any such payment so remitted shall be repaid to the Swingline
Lender or to the Administrative Agent, as applicable, if and to the extent such payment is required to be refunded to the Borrower for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve the
Borrower of any default in the payment thereof. On any Business Day, the Swingline Lender may, in its sole discretion, give notice requesting Revolving Lenders to make Revolving Loans that are ABR Loans on such funding date in an amount equal to the
amount of such Swingline Loans. Each Swingline Loan will be repaid no later than every Friday (or the next succeeding Business Day). 
 (d) (i) Notwithstanding anything to the contrary contained in this Agreement, if any Swingline Exposure exists at the time a Lender becomes a Defaulting Lender then: 
  

	 	(a)	all or any part of such Swingline Exposure shall be reallocated (in whole or in part) among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but
only to the extent (x) the sum of all non-Defaulting Lenders’ Exposures plus such Defaulting Lender’s LC Exposure that is allocated pursuant to Section 2.05(b)(ii)(a) to the non-Defaulting Lenders and Swingline Exposure does not
exceed the total of all non-Defaulting Lenders’ Commitments and (y) the conditions set forth in Section 4.02 are satisfied at such time (it being understood that the Administrative Agent shall provide the Borrower with the amounts
reallocated; provided, that the failure to provide such notice shall not relieve the Borrower from its obligations set forth in this Section 2.04(d)); and 

  

 -42- 

	 	(b)	if the reallocation described in clause (a) above cannot, or can only partially, be effected, within 3 Business Days after the Administrative Agent (or the Required Lenders)
have sent notice to the Borrower that a Lender has become a Defaulting Lender the Borrower shall enter into arrangements satisfactory to it and the Swingline Lender cash collateralizing such Defaulting Lender’s Swingline Exposure (after giving
effect to any partial reallocation pursuant to clause (a) above) (such arrangements, the “Swingline Back-Stop Arrangements”) for so long as such Swingline Exposure is outstanding. 

 (ii) So long as any Lender is a Defaulting Lender, the Swingline Lender shall not be required to fund any Swingline Loan, unless the
related exposure is 100% covered by the Commitments of the non-Defaulting Lenders or cash collateral is provided by the Borrower as set forth above and participating interests in any such newly made Swingline Loan shall be allocated among
non-Defaulting Lenders in a manner consistent with Section 2.04(d) (and Defaulting Lenders shall not participate therein). 
 (e) Subject to the appointment and acceptance of a successor Swingline Lender as provided in this paragraph (except as provided in Section 8.01(f)), the Swingline Lender may resign at any time upon 15 days’ prior notice to the
Lenders, the Administrative Agent and unless a Default or Event of Default exists, the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor to the Swingline Lender which successor shall be consented
to by the Borrower at all times other than during the existence of an Event of Default under Section 7.01(h), (i) or (j). If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within
15 days after the resigning Swingline Lender gives notice of its resignation, then the retiring Swingline Lender may (but shall have no obligation to), on behalf of the Lenders and the Administrative Agent, appoint a successor Swingline Lender which
shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Swingline Lender hereunder by a successor, such successor shall succeed to and become vested with all the
rights, powers, privileges and duties of the resigning Swingline Lender (but the resigning Swingline Lender shall maintain all of its rights, powers and privileges with respect to Swingline Loans made by it prior to the date of such resignation.

 SECTION 2.05. Letters of Credit. (a) General. Upon satisfaction of the conditions specified in Section 4.01 on the
Effective Date, each Existing Letter of Credit will, automatically and without any action on the part of any Person, be deemed to be a Letter of Credit issued hereunder for all purposes of this Agreement and the other Loan Documents. In addition,
subject to the terms and conditions set forth herein, the Borrower may request the issuance of additional Letters of Credit for its own account (or for the account of any of its subsidiaries so long as the Borrower is a co-applicant), in a form
reasonably acceptable to the 

  

 -43- 

 
Administrative Agent and the Issuing Bank, at any time and from time to time during the Availability Period. In the event of any inconsistency between the
terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of Credit,
the terms and conditions of this Agreement shall control. 
 (b) Notice of Issuance, Amendment, Renewal, Extension; Certain
Conditions. (i) To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements
for doing so have been approved by the Issuing Bank) to the Issuing Bank (except that the Issuing Bank in respect of Existing Letters of Credit shall not issue additional Letters of Credit and shall not be required to renew or extend an Existing
Letter of Credit unless agreed by it) and the Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a Letter of Credit Request requesting the issuance of a Letter of Credit, or identifying
the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with
paragraph (c) of this Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. All Letters of
Credit will be denominated in U.S. Dollars and will be payable on a sight basis. If requested by the Issuing Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank’s standard form in connection with any request
for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving
effect to such issuance, amendment, renewal or extension the Aggregate Exposures shall not exceed the aggregate Commitments. 
 (ii)
Notwithstanding anything to the contrary contained in this Agreement, if any LC Exposure exists at the time a Lender becomes a Defaulting Lender then: 
  

	 	(a)	all or any part of such LC Exposure shall be reallocated (in whole or in part) among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only
to the extent (x) the sum of all non-Defaulting Lenders’ Exposures plus such Defaulting Lender’s LC Exposure and Swingline Exposure that is allocated pursuant to Section 2.04(d)(i)(a) to the non-Defaulting Lenders does not exceed
the total of all non-Defaulting Lenders’ Commitments and (y) the conditions set forth in Section 4.02 are satisfied at such time (it being understood that the Administrative Agent shall provide the Borrower with the amounts
reallocated; provided, that the failure to provide such notice shall not relieve the Borrower from its obligations set forth in this Section 2.05(b)); 

  

	 	(b)	 if the reallocation described in clause (a) above cannot, or can only partially, be effected, within 10 Business Days after the Administrative 

  

 -44- 

	 	 
Agent (or the Required Lenders) have sent notice to the Borrower that a Lender has become a Defaulting Lender the Borrower shall enter into arrangements cash
collateralizing such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (a) above) in accordance with the procedures set forth in Section 2.05(j) (such arrangements, the “Letter
of Credit Back-Stop Arrangements”) for so long as such LC Exposure is outstanding; 

  

	 	(c)	if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to this Section 2.05(b), the Borrower shall not be required to pay any
fees to such Defaulting Lender pursuant to Section 2.12 with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized; 

  

	 	(d)	if any of the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to this Section 2.05(b), then the fees payable to the Lenders pursuant to Section 2.12
shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable Percentages; and 

  

	 	(e)	if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to this Section 2.05(b), then without prejudice to any rights or remedies of
any Issuing Bank or any Lender hereunder, all letter of credit fees payable under Section 2.12 with respect to such Defaulting Lender’s LC Exposure shall be payable to such Issuing Bank until such LC Exposure is cash collateralized or
reallocated. 

 (iii) So long as any Lender is a Defaulting Lender, no Issuing Bank shall be required to issue,
amend or increase any Letter of Credit, unless the related exposure is 100% covered by the Commitments of the non-Defaulting Lenders or cash collateral is provided by the Borrower in accordance with Section 2.05(b) and participating interests
in any such newly issued or increased Letter of Credit shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.05(b) (and Defaulting Lenders shall not participate therein). 
 (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date
that is one year after the date of the issuance of such Letter of Credit; provided that any Letter of Credit may provide for renewals or extensions thereof (automatic or otherwise) for additional periods of up to 12 months (which in no event
shall extend beyond the date referred to in clause (ii)) and (ii) the date that is five Business Days prior to the Maturity Date. 
 (d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the
Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such
Letter of Credit. In consideration and in 

  

 -45- 

 
furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing
Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be
refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any
circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any
offset, abatement, withholding or reduction whatsoever. 
 (e) Reimbursement. If the Issuing Bank shall make any
LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 3:00 p.m., New York City time,
on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by the Borrower
prior to such time on such date, then not later than (i) 3:00 p.m., New York City time, on the Business Day that the Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York City time on the
day of receipt, or (ii) 3:00 p.m., New York City time, on the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt, provided
that the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.03 or 2.04 that such payment be financed with an ABR Borrowing or Swingline Loan in an equivalent amount and, to the extent so
financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing or Swingline Loan. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender
of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice and subject to Section 2.05(b)(ii), each Lender
shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.06 with respect to Loans made by such Lender (and Section 2.06 shall apply,
mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of
any payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to
such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing Bank for any LC Disbursement (other than the funding of ABR Loans or a Swingline Loan as
contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement. 
  

 -46- 

 (f) Obligations Absolute. The Borrower’s obligation to reimburse
LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and
irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or
invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such
Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff
against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or
transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or
delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes
beyond the control of the Issuing Bank, provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential or punitive damages, claims
in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents
presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent
jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented that appear
on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any
notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit. 
 (g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to
represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will
make an LC Disbursement thereunder, provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such
LC Disbursement in accordance with paragraph (e) of this Section. 
  

 -47- 

 (h) Interim Interest. If the Issuing Bank shall make any LC Disbursement,
then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to
but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans, provided that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to
paragraph (e) of this Section, then Section 2.13(c) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant
to paragraph (e) of this Section to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment. 
 (i) Replacement of the Issuing Bank. Subject to the appointment and acceptance of a successor Issuing Bank as provided in this paragraph (except as provided in Section 8.01(f)), the Issuing Bank may resign
at any time upon 15 days’ prior notice to the Administrative Agent, the Lenders and unless a Default or Event of Default exists, the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor which
successor shall be consented to by the Borrower at all times other than during the existence of an Event of Default under Section 7.01(h), (i) or (j). If no successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 15 days after the resigning Issuing Bank gives notice of its resignation, then the retiring Issuing Bank may (but shall have no obligation to), on behalf of the Lenders and the Administrative Agent, appoint a
successor Issuing Bank which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. At the time any such replacement and/or resignation shall become effective, the Borrower shall pay all unpaid fees accrued
for the account of the replaced Issuing Bank pursuant to Section 2.12(b). From and after the effective date of any such replacement and/or resignation, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing
Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor
and all previous Issuing Banks, as the context shall require. After the replacement and/or resignation of the Issuing Bank hereunder, the replaced or resigning Issuing Bank shall remain a party hereto and shall continue to have all the rights and
obligations of the Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement and/or resignation, but shall not be required to issue additional Letters of Credit. 
 (j) Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives
notice from the Administrative Agent or the Required Lenders demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Collateral Agent, in the name of the Collateral Agent and for the
benefit of the Lenders, an amount in cash equal to 105% the LC Exposure as of such date plus any accrued and unpaid interest thereon, provided that the obligation to deposit such cash collateral shall become effective immediately, and
such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event 

  

 -48- 

 
of Default with respect to the Borrower described in paragraph (h) or (i) of Section 7.01. The Borrower also shall deposit cash collateral
pursuant to this paragraph as and to the extent required by Section 2.11(b). Each such deposit shall be held by the Collateral Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The
Collateral Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole
discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by
the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the
LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of the Required Lenders), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to
provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have
been cured or waived. 
 SECTION 2.06. Funding of Borrowings. (a) Each Lender shall make each Loan to be made by
it hereunder on the proposed date thereof by wire transfer of immediately available funds by 12:00 noon, New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the
Lenders, provided that Swingline Loans shall be made as provided in Section 2.04. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the
Borrower maintained with the Administrative Agent in New York City and designated by the Borrower in the applicable Borrowing Request, provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in
Section 2.05(e) shall be remitted by the Administrative Agent to the Issuing Bank. 
 (b) Unless the Administrative Agent
shall have received notice from a Lender prior to the proposed 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 paragraph (a) of this Section and may, in reliance upon such assumption and in its sole discretion, make available to the Borrower a corresponding amount. In such event, if a Lender has not
in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower 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 to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate
and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the
Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing. 
  

 -49- 

 SECTION 2.07. Interest Elections. (a) Each Borrowing initially shall be of the Type specified
in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request or as designated by Section 2.03. Thereafter, the Borrower may elect to convert such
Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions
of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section
shall not apply to Swingline Borrowings, which may not be converted or continued. 
 (b) To make an election pursuant to this
Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Borrowing of the Type resulting from such
election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election
Request signed by the Borrower. 
 (c) Each telephonic and written Interest Election Request shall specify the following
information in compliance with Section 2.02: 
 (i) the Borrowing to which such Interest Election Request applies and, if
different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall
be specified for each resulting Borrowing); 
 (ii) the effective date of the election made pursuant to such Interest Election
Request, which shall be a Business Day; 
 (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar
Borrowing; and 
 (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto
after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”. 
 If any such Interest
Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. 
 (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof
and of such Lender’s portion of each resulting Borrowing. 
 (e) If the Borrower fails to deliver a timely Interest
Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable 

  

 -50- 

 
thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing.
Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing,
(i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

 SECTION 2.08. Termination and Reduction of Commitments. (a) Unless previously terminated, the Commitments shall terminate on
the Maturity Date. 
 (b) The Borrower may at any time terminate, or from time to time reduce, the Commitments,
provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $500,000 and not less than $2,000,000 and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving
effect to any concurrent prepayment of the Revolving Loans in accordance with Section 2.11, the Aggregate Exposures would exceed the aggregate Commitments. 
 (c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of
this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the
Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable, provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned
upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or
reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments. 
 SECTION 2.09. Repayment of Loans; Evidence of Debt. (a) The Borrower hereby unconditionally promises to pay (i) to the
Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan of such Lender on the Maturity Date, (ii) to the Swingline Lender the then unpaid principal amount of each Swingline Loan on the
Maturity Date, provided that on each date that a Borrowing is made, the Borrower shall repay all Swingline Loans that were outstanding on the date such Borrowing was requested. 
 (b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to
such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. 
 (c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type
thereof and the Interest 

  

 -51- 

 
Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender
hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof. 
 (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie
evidence of the existence and amounts of the obligations recorded therein, provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the
Borrower to repay the Loans in accordance with the terms of this Agreement. 
 (e) Any Lender may request that Loans made by
it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns)
and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory
notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns). 
 SECTION 2.10. [Intentionally Omitted] 
 SECTION 2.11. Prepayment of Loans. (a) The Borrower
shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to the requirements of this Section. 
 (b) In the event and on such occasion that the Aggregate Exposures exceed the aggregate Commitments, the Borrower shall prepay Borrowings or Swingline Borrowings (or, if no such Borrowings are outstanding, deposit
cash collateral in an account with the Collateral Agent pursuant to Section 2.05(j)) in an aggregate amount equal to such excess. 
 (c) [intentionally omitted]. 
 (d) Prior to any optional or mandatory prepayment of
Borrowings hereunder, the Borrower shall select the Borrowing or Borrowings to be prepaid and shall specify such selection in the notice of such prepayment pursuant to paragraph (e) of this Section. 
 (e) The Borrower shall notify the Administrative Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by
telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, three Business Days before the date of prepayment, (ii) in the
case of prepayment of an ABR Borrowing, not later than 12:00 noon, New York City time, one Business Day before the date of prepayment or (iii) in the case of prepayment of a Swingline Loan, not later than 2:00 p.m., 

  

 -52- 

 
New York City time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date, the principal amount of each
Borrowing or portion thereof to be prepaid and, in the case of a mandatory prepayment, a reasonably detailed calculation of the amount of such prepayment, provided that, if a notice of optional prepayment is given in connection with a
conditional notice of termination of the Commitments as contemplated by Section 2.08, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.08. Promptly following receipt of any
such notice (other than a notice relating solely to Swingline Loans), the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an
advance of a Borrowing of the same Type as provided in Section 2.02, except as necessary to apply fully the required amount of a mandatory prepayment. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid
Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.13 but shall otherwise be without premium or penalty. 
 SECTION 2.12. Fees. (a) With the exception of a Defaulting Lender subject to Section 2.21 below, the Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee,
which shall accrue at 1.00% on the daily unused amount of each Commitment of such Lender during the period from and including the Effective Date to but excluding the date on which the aggregate Commitments terminate. Accrued commitment fees shall be
payable in arrears in respect of the Commitments, on the last Business Day of March, June, September and December of each year and on the date on which the Commitments terminate, commencing on the first such date to occur after the date hereof. All
commitment fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). For purposes of computing commitment fees with respect to
Commitments, a Commitment of a Lender shall be deemed to be used to the extent of the outstanding Revolving Loans and LC Exposure of such Lender (and the Swingline Exposure of such Lender shall be disregarded for such purpose). 
 (b) The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its
participations in Letters of Credit, which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Eurodollar Loans on the daily amount of such Lender’s LC Exposure (excluding any portion thereof
attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any
LC Exposure, and (ii) to the Issuing Bank a fronting fee, which shall accrue at a rate equal to 0.25% per annum on the daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed
LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, as well as the Issuing Bank’s
standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees shall be payable on the last Business Day of March, June, September and
December of each year, commencing on the first 

  

 -53- 

 
such date to occur after the Effective Date, provided that all such fees shall be payable on the date on which the Commitments terminate and any such
fees accruing after the date on which the Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within 10 days after demand. All participation fees and fronting
fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). 
 (c) The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately
agreed upon between the Borrower and the Administrative Agent. 
 (d) All fees payable hereunder shall be paid on the dates
due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of commitment fees and participation fees, to the Lenders entitled thereto. Fees paid shall
not be refundable under any circumstances. 
 SECTION 2.13. Interest. (a) The Loans comprising each ABR Borrowing (including
each Swingline Loan) shall bear interest at the Alternate Base Rate plus the Applicable Rate. 
 (b) The Loans comprising each
Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate. 
 (c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or
otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding
paragraphs of this Section or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section. 
 (d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and, in the case of Revolving
Loans, upon termination of the Commitments, provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a
prepayment of an ABR Loan prior to the end of the Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any
Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion. 
  

 -54- 

 (e) All interest hereunder shall be computed on the basis of a year of 360 days,
except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case
shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate or Adjusted LIBO Rate shall be determined by the Administrative Agent, and such determination shall be
conclusive absent manifest error. 
 SECTION 2.14. Alternate Rate of Interest. If prior to the commencement of any Interest Period for
a Eurodollar Borrowing: 
 (a) the Administrative Agent determines (which determination shall be conclusive absent manifest
error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate for such Interest Period; or 
 (b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such
Borrowing for such Interest Period; 
 then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as
promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of
any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing. 
 SECTION 2.15. Increased Costs. (a) If any Change in Law shall: 
 (i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the
account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the Issuing Bank; or 
 (ii) impose on any Lender or the Issuing Bank or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein;

 and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make any such Loan) or to increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or the Issuing
Bank hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender or the Issuing Bank, as applicable, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as applicable, for such
additional costs incurred or reduction suffered. 
  

 -55- 

 (b) If any Lender or the Issuing Bank determines that any Change in Law regarding capital
requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this
Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing
Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with
respect to capital adequacy), then from time to time the Borrower will pay to such Lender or the Issuing Bank, as applicable, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing
Bank’s holding company for any such reduction suffered. 
 (c) A certificate of a Lender or the Issuing Bank setting
forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as applicable, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive
absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as applicable, the amount shown as due on any such certificate within 10 days after receipt thereof. 
 (d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a
waiver of such Lender’s or the Issuing Bank’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs or
reductions incurred more than 270 days prior to the date that such Lender or the Issuing Bank, as applicable, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing
Bank’s intention to claim compensation therefor, provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include
the period of retroactive effect thereof. 
 SECTION 2.16. Break Funding Payments. In the event of (a) the payment of any
principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period
applicable thereto, (c) the failure to borrow, convert, continue or prepay any Revolving Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(e) and is
revoked in accordance therewith), 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 pursuant to Section 2.19, then, in any such event,
the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the
excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such
event to the last day of the then 

  

 -56- 

 
current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for
such Loan), over (ii) the amount of interest that would accrue on such principal amount for such period at the interest rate that such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable
amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive
absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 
 SECTION 2.17. Taxes. (a) Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other
Taxes, provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender or Issuing Bank (as applicable) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower
shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 
 (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

 (c) The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 30 days after
written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as applicable, on or with respect to any payment by or on account of any obligation of the
Borrower hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or
with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by
a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error. 
 (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower
shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, if any, a copy of the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent. 
 (e) Any Foreign Lender that is entitled to an exemption from or reduction of
withholding tax under the law of the jurisdiction in which the Borrower is 

  

 -57- 

 
located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the
Administrative Agent), on or prior to the Effective Date in the case of each Foreign Lender that is a signatory hereto, and on the date of assignment pursuant to which it becomes a Lender in the case of each other Lender and from time to time
thereafter is reasonably requested by either of the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made
without withholding or at a reduced rate. 
 (f) If the Administrative Agent or a Lender determines, in its sole discretion,
that it has received a refund of any Indemnified Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 2.17, it shall pay over such
refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.17 with respect to the Indemnified Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that the Borrower, upon the request of the
Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the
Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information
relating to its taxes that it deems confidential) to the Borrower or any other Person. 
 SECTION 2.18. Payments Generally; Pro Rata
Treatment; Sharing of Set-offs. (a) The Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts
payable under Section 2.15, 2.16 or 2.17, or otherwise) prior to the time expressly required hereunder or under such other Loan Document for such payment (or, if no such time is expressly required, prior to 3:00 p.m., New York City
time), on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 60 Wall Street, New York, New York 10005, except payments to be made directly to the Issuing Bank or
Swingline Lender as expressly provided herein and except that payments pursuant to Sections 2.15, 2.16, 2.17 and 9.03 shall be made directly to the Persons entitled thereto and payments pursuant to other Loan Documents shall be made to the
Persons specified therein. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment under any Loan Document shall
be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All
payments under each Loan Document shall be made in dollars. 
  

 -58- 

 (b) If at any time insufficient funds are received by and available to the Administrative
Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto
in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties. 
 (c) If any
Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Revolving Loans or participations in LC Disbursements or Swingline Loans resulting in such
Lender receiving payment of a greater proportion of the aggregate amount of its Revolving Loans, and participations in LC Disbursements and Swingline Loans and accrued interest thereon than the proportion received by any other Lender, then the
Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Revolving Loans, and participations in LC Disbursements and Swingline Loans of other Lenders to the extent necessary 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 Revolving Loans, and participations in LC Disbursements and Swingline Loans,
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 any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as
consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the
provisions of this paragraph shall apply). The Borrower 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 Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. 
 (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the
Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may,
in reliance upon such assumption and in its sole discretion, distribute to the Lenders or the Issuing Bank, as applicable, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing
Bank, as applicable, severally agrees to 

  

 -59- 

 
repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and
including the date such amount is distributed to it to but excluding the date of payment to 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. 
 (e) If any Lender shall fail to make any payment required to be made by it
pursuant to Section 2.04(c), 2.05(d) or (e), 2.06(a), 2.18(d) or 9.03(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent
for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. 
 SECTION 2.19. Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.17, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and 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 2.15 or 2.17, as applicable, 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 Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any
such designation or assignment. 
 (b) If any Lender requests compensation under Section 2.15, or if the Borrower is
required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower 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 Section 9.04), all its interests, rights
and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that (i) the Borrower shall have received the prior written
consent of the Administrative Agent, the Issuing Bank and the Swingline Lender, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and
participations in LC Disbursements and Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the
Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result
in a material reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to
require such assignment and delegation cease to apply. 
  

 -60- 

 SECTION 2.20. Incremental Commitments. At any time during the Availability Period, subject to the
terms and conditions set forth herein, the Borrower may at any time and from time to time, by notice to the Administrative Agent (whereupon the Administrative Agent shall promptly deliver a copy to each of the Lenders), request to add additional
Commitments (together the “Incremental Extensions of Credit”) in minimum principal amounts of $5,000,000, provided that such amount may be less than $5,000,000 if such amount represents all the remaining availability under
the aggregate principal amount set forth below, provided, further, that (x) immediately prior to and after giving effect to any Incremental Facility Amendment, no Default has occurred or is continuing or shall result therefrom and
(y) the Borrower shall be in compliance on a Pro Forma Basis with the Financial Performance Covenant recomputed as of the last day of the most recently ended fiscal quarter of the Borrower for which financial statements are available. The
Incremental Extensions of Credit (a) shall be in an aggregate principal amount not exceeding $20,000,000 and (b) shall have the same terms as the Commitments. The Borrower may chose to offer each Lender (an “Existing
Lender”) the opportunity to commit to the Incremental Extensions of Credit; provided that no Existing Lender shall be obligated to provide any Incremental Extensions of Credit unless it so agrees. Any additional bank, financial
institution, Existing Lender or other Person that elects to extend Incremental Extensions of Credit shall be reasonably satisfactory to the Administrative Agent (any such bank, financial institution, Existing Lender or other Person being called an
“Additional Lender”) and shall become a Lender under this Agreement, pursuant to an amendment (an “Incremental Facility Amendment”) to this Agreement, giving effect to the modifications permitted by this
Section 2.20, and, as appropriate, the other Loan Documents, executed by the Borrower, each Additional Lender and the Administrative Agent. Commitments in respect of Incremental Extensions of Credit shall be Commitments for all purposes under
this Agreement. An Incremental Facility Amendment may, without the consent of any other Lenders, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the opinion of the Administrative Agent, to
effect the provisions of this Section. The effectiveness of any Incremental Facility Amendment shall be subject to the satisfaction on the date thereof (each, an “Incremental Facility Closing Date”) of each of the conditions set
forth in Section 4.02 (it being understood that all references to “the date of such Borrowing” in such Section 4.02 shall be deemed to refer to the Incremental Facility Closing Date). Upon each increase in the Commitments
pursuant to this Section 2.20, each Existing Lender will automatically and without further act be deemed to have assigned to each Additional Lender providing a portion of the Incremental Extension of Credit, and each such Additional Lender will
automatically and without further act be deemed to have assumed, a portion of such Existing Lender’s participations hereunder in outstanding Letters of Credit and Swingline Loans such that, after giving effect to each such deemed assignment and
assumption of participations, the percentage of the aggregate outstanding (i) participations hereunder in Letters of Credit and (ii) participations hereunder in Swingline Loans held by each Lender (including each such Additional Lender)
will equal such Lender’s Applicable Percentage and (b) if, on the date of such increase, there are any Revolving Loans outstanding, such Revolving Loans shall on the Incremental Facility Closing Date be prepaid from the proceeds of
additional Revolving Loans made hereunder (reflecting such increase in Commitments), which prepayment shall be accompanied by accrued interest on the Revolving Loans being prepaid and any costs incurred 

  

 -61- 

 
by any Lender in accordance with Section 2.16. The Administrative Agent and the Lenders hereby agree that the minimum borrowing, pro rata borrowing and
pro rata payment requirements contained elsewhere in this Agreement shall not apply to the transactions effected pursuant to the immediately preceding sentence. The proceeds of the Incremental Extensions of Credit shall be used for the purposes set
forth in Section 5.11. 
 SECTION 2.21. Defaulting Lenders. Anything contained herein to the contrary notwithstanding, in the
event that any Lender becomes a Defaulting Lender by defaulting in its obligation to fund (a “Funding Default”) any Revolving Loan or its portion of any unreimbursed payment under Section 2.04(c) or 2.05(d) (in each case, a
“Defaulted Loan”) or otherwise becomes a Defaulting Lender, then (a) during any Default Period with respect to such Defaulting Lender, such Defaulting Lender shall be deemed not to be a “Lender” for purposes of voting
on any matters (including the granting of any consents or waivers) with respect to any of the Loan Documents other than matters pertaining to (i) increasing the Commitment of such Defaulting Lender, (ii) reducing the principal amount of
any Loan or LC Disbursement or reducing the rate of interest thereon, or reducing any fees payable under this Agreement, in each case owed to such Defaulting Lender, or (iii) postponing the maturity of any Loan, the required date of
reimbursement of any LC Disbursement, in each case owed to such Defaulting Lender or postponing the scheduled date of expiration of the Commitment of such Defaulting Lender; (b) to the extent permitted by applicable law, until such time as the
Default Excess with respect to such Defaulting Lender shall have been reduced to zero, (i) any voluntary prepayment of the Revolving Loans shall, if the Borrower so directs at the time of making such voluntary prepayment, be applied to the
Revolving Loans of other Lenders as if such Defaulting Lender had no Revolving Loans outstanding and the Exposure of such Defaulting Lender were zero and (ii) any mandatory prepayment of the Revolving Loans shall, if the Borrower so directs at
the time of making such mandatory prepayment, be applied to the Revolving Loans of other Lenders (but not to the Revolving Loans of such Defaulting Lender) as if such Defaulting Lender had funded all Defaulted Loans of such Defaulting Lender, it
being understood and agreed that the Borrower shall be entitled to retain any portion of any mandatory prepayment of the Revolving Loans that is not paid to such Defaulting Lender solely as a result of the operation of the provisions of this clause
(b); and (c) subject to Section 2.05(b), such Defaulting Lender’s Commitment and outstanding Revolving Loans and such Defaulting Lender’s pro rata share of the LC Exposure shall be excluded for purposes of calculating the
commitment fee payable to Lenders in respect of any day during any Default Period with respect to such Defaulting Lender, and such Defaulting Lender shall not be entitled to receive any commitment fee pursuant to Section 2.12 with respect to
such Defaulting Lender’s Commitment in respect of any Default Period with respect to such Defaulting Lender. No Commitment of any Lender shall be increased or otherwise affected, and, except as otherwise expressly provided in this
Section 2.21, performance by the Borrower of its obligations hereunder and the other Loan Documents shall not be excused or otherwise modified as a result of any Funding Default or the operation of this Section 2.21. The rights and
remedies against a Defaulting Lender under this Section 2.21 are in addition to other rights and remedies which the Borrower may have against such Defaulting Lender with respect to any Funding Default and which the Administrative Agent, the
Swingline Lender, any Issuing Bank or any Lender may have against such Defaulting Lender with respect to any Funding Default.

 Representations and Warranties 
 Holdings and the Borrower represent and warrant to the Lenders that:

 SECTION 3.01. Organization; Power. Each of Holdings, the Borrower and the Subsidiaries (a) is duly organized, validly existing
and in good standing under the laws of the jurisdiction of its organization, (b) has the power and authority and all governmental rights, qualifications, approvals, authorizations, permits, accreditations, Reimbursement Approvals, licenses and

obligations under each Loan Document to which it is a party and (c) except where the failure to do so, individually or in the aggregate, is not reasonably likely to result in a Material Adverse Effect, is qualified to do business in, and is in
good standing in, every jurisdiction where such qualification is required. 
 SECTION 3.02. Authorization; Enforceability. The
Transactions to be entered into by each Loan Party have been duly authorized by all necessary corporate or other action and, if required, stockholder action. This Agreement has been duly executed and delivered by each of Holdings and the Borrower
and constitutes, and each other Loan Document to which any Loan Party is to be a party, when executed and delivered by such Loan Party, will constitute, a legal, valid and binding obligation of Holdings, the Borrower or such Loan Party, as
applicable, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of
whether considered in a proceeding in equity or at law. 
 SECTION 3.03. Governmental Approvals; No Conflicts. The Transactions
(a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect and except filings necessary to perfect
Liens created under the Loan Documents, (b) will not violate any Requirement of Law applicable to Holdings, the Borrower or any of the Subsidiaries, as applicable, (c) will not violate or result in a default under any indenture, Management
Services Agreement or other material agreement or instrument binding upon Holdings, the Borrower or any of the Subsidiaries or its assets, or give rise to a right thereunder to require any payment to be made by Holdings, the Borrower or any of the
Subsidiaries or give rise to a right of, or result in, termination, cancellation or acceleration of any material obligation thereunder, (d) will not result in a Limitation on any right, qualification, approval, permit, accreditation,
authorization, Reimbursement Approval, license or franchise or authorization granted by any Governmental Authority, Third Party Payor or other Person applicable to the business, operations or assets of the Borrower or any of the Subsidiaries or
adversely affect the ability of the Borrower or any of the Subsidiaries to participate in any Third Party Payor Arrangement except for Limitations, individually or in the aggregate, that are not material to the business of the Borrower and the
Subsidiaries, taken as a whole, and (e) will not result in the creation or imposition of any Lien on any asset of Holdings, the Borrower or any of the Subsidiaries, except Liens created under the Loan Documents. There is no pending or, to the
knowledge of the Borrower, threatened Limitation by any Governmental Authority, Third Party 

  

 -63- 

 
Payor or any other Person of any right, qualification, approval, permit, authorization, accreditation, Reimbursement Approval, license or franchise of the
Borrower, any Subsidiary or any Affiliated Practice, except for such Limitations, individually or in the aggregate, as are not reasonably likely to result in a Material Adverse Effect. No certifications by any Governmental Authority or any Third
Party Payor are required for operation of the business of the Borrower and the Subsidiaries and neither the Borrower nor any Subsidiary is required to have entered into any agreement with a Third Party Payor for the operation of the business of the
Borrower and the Subsidiaries that are not in place, in each case except such certifications or the absence of agreements which do not materially and adversely affect the operation of the business of the Borrower and its Subsidiaries. All material
Affiliated Practices have the power and authority, all governmental rights, qualifications, permits, authorizations, approvals, accreditations, Reimbursement Approvals, licenses and franchises material to the business of the Borrower and the
Subsidiaries, taken as a whole, that are necessary to own its assets and to carry on its business as now conducted and as proposed to be conducted. 
 SECTION 3.04. Financial Condition; No Material Adverse Change. (a) The Borrower has heretofore furnished to the Lenders its consolidated balance sheet and consolidated statements of operations and comprehensive income,
stockholders’ equity and cash flows (i) as of and for the fiscal years ended December 31, 2006, December 31, 2007, and December 31, 2008, reported on by PricewaterhouseCoopers LLP, independent public accountants, and
(ii) as of and for the fiscal quarter ended March 31, 2009 (and comparable period for the prior fiscal year), certified by its chief financial officer. Such financial statements present fairly, in all material respects, the financial
position and results of operations and cash flows of the Borrower and the Subsidiaries as of such dates and for such periods in accordance with GAAP consistently applied, subject to year-end audit adjustments and the absence of footnotes in the case
of the statements referred to in clause (ii) above. 
 (b) Except as disclosed in (i) the financial statements
referred to above or the notes thereto or (ii) the Final Offering Memorandum, none of the Borrower or its Subsidiaries has, as of the Effective Date, any material direct or contingent liabilities. 
 (c) No event, change or condition has occurred that has had, or is reasonably likely to have, a material adverse effect on the business,
operations, assets, liabilities, financial condition or results of operations of Holdings, the Borrower and the Subsidiaries, taken as a whole, since December 31, 2008. 
 SECTION 3.05. Properties. (a) Each of Holdings, the Borrower and the Subsidiaries has good title to, or valid leasehold interests in, all its
real and personal property material to its business (including its Mortgaged Properties), free and clear of all Liens, except for Permitted Encumbrances and minor defects in title that do not interfere in any material respect with its ability to
conduct its business or to utilize such properties for their intended purposes. 
 (b) Each of Holdings, the Borrower and the
Subsidiaries owns, licenses or possesses the right to use, all Intellectual Property (as defined in the Collateral Agreement) material to its business, and the use thereof by Holdings, the Borrower and the Subsidiaries does not infringe upon the
rights of any other Person, except for any such infringements that, individually or in the aggregate, are not reasonably likely to result in a Material Adverse Effect. 
  

 -64- 

 (c) Schedule 3.05 sets forth the address of each real property that is owned or
leased by Holdings, the Borrower or any of the Subsidiaries as of the Effective Date. 
 (d) As of the Effective Date, neither
Holdings or the Borrower nor any of the Subsidiaries has received notice of, or has knowledge of, any pending or contemplated condemnation proceeding affecting any Mortgaged Property or any sale or disposition thereof in lieu of condemnation. As of
the Effective Date, neither any Mortgaged Property nor any interest therein is subject to any right of first refusal, option or other contractual right to purchase such Mortgaged Property or interest therein. 
 SECTION 3.06. Litigation and Environmental Matters. (a) There are no actions, suits or proceedings by or before any arbitrator or
Governmental Authority pending against or, to the knowledge of Holdings, the Borrower or any Subsidiary, threatened against or affecting Holdings, the Borrower or any Subsidiary that are reasonably likely to (i) have a Material Adverse Effect
or (ii) adversely affect in any material respect the ability of the Loan Parties to consummate the Transactions or the other transactions contemplated hereby. 
 (b) Except with respect to any other matters that, individually or in the aggregate, are not reasonably likely to result in a Material
Adverse Effect, neither Holdings, the Borrower nor any Subsidiary (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any Environmental Law,
(ii) has become subject to any Environmental Liability, (iii) has received notice of any claim with respect to any Environmental Liability or (iv) knows of any basis for any Environmental Liability. 
 SECTION 3.07. Compliance with Laws and Agreements. Except with respect to any matters that, individually or in the aggregate, are not material to
the business of the Borrower and the Subsidiaries, taken as a whole, each of Holdings, the Borrower, the Subsidiaries and, to the knowledge of the Borrower, the Affiliated Practices, is in compliance with all material Requirements of Law applicable
to it or its property and all material indentures, agreements and other instruments binding upon it or its property, including the Health Insurance Portability and Accountability Act of 1996 (HIPAA) and all related regulations. 
 SECTION 3.08. Investment Company Status. Neither Holdings, the Borrower nor any Subsidiary is an “investment company” as defined in, or
subject to regulation under, the Investment Company Act of 1940 as amended from time to time. 
 SECTION 3.09. Taxes. Each of
Holdings, the Borrower and the Subsidiaries has timely filed or caused to be filed all Federal and other material Tax returns and reports required to have been filed and has paid or caused to be paid all Taxes required to have been paid by it,
except (a) any Taxes that are being contested in good faith by appropriate proceedings and for which Holdings, the Borrower or such Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with GAAP or (b) to
the extent that the failure to do so is not reasonably likely to result in a Material Adverse Effect. 
  

 -65- 

 SECTION 3.10. ERISA. No ERISA Event has occurred or is reasonably likely to occur that, when taken
together with all other such ERISA Events for which liability is reasonably likely to occur, is reasonably likely to result in a Material Adverse Effect. The present value of all accumulated benefit obligations under each Plan (based on the
assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair value of the assets of such Plan. 
 SECTION 3.11. Disclosure. None of the written reports, financial statements, certificates or other written information furnished by or on behalf
of any Loan Party to the Administrative Agent or any Lender in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder or thereunder (as modified or supplemented by other information so furnished), taken
as a whole, contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, provided that with respect to
any projected financial information, Holdings and the Borrower represent only that such information was prepared in good faith based upon assumptions believed by it to be reasonable at the time delivered and as of the Effective Date. 
 SECTION 3.12. Subsidiaries. As of the Effective Date, Holdings does not have any subsidiaries other than the Borrower and the Subsidiaries,
Permitted Joint Ventures and Inactive Subsidiaries listed on Schedule 3.12. Schedule 3.12 sets forth the name of, and the ownership or beneficial interest of Holdings, in each subsidiary, including the Borrower, and identifies each
Subsidiary that is a Subsidiary Loan Party, in each case as of the Effective Date. 
 SECTION 3.13. Insurance. Schedule 3.13 sets
forth a description of all insurance maintained by or on behalf of Holdings, the Borrower and the Subsidiaries as of the Effective Date. As of the Effective Date, all premiums in respect of such insurance have been paid. Holdings and the Borrower
believe that the insurance maintained by or on behalf of the Borrower and the Subsidiaries is adequate. 
 SECTION 3.14. Labor
Matters. As of the Effective Date, there are no strikes, lockouts or slowdowns against Holdings, the Borrower or any Subsidiary pending or, to the knowledge of Holdings or the Borrower, threatened. The hours worked by and payments made to
employees of the Borrower and the Subsidiaries have not been in violation of the Fair Labor Standards Act or any other applicable Federal, state, local or foreign law dealing with such matters. All payments due from Holdings, the Borrower or any
Subsidiary, or for which any claim may be made against Holdings, the Borrower or any Subsidiary, on account of wages and employee health and welfare insurance and other benefits, have been paid or accrued as a liability on the books of Holdings, the
Borrower or such Subsidiary. The consummation of the Transactions will not give rise to any right of termination or right of renegotiation on the part of any union under any collective bargaining agreement to which Holdings, the Borrower or any
Subsidiary is bound. 
  

 -66- 

 SECTION 3.15. Solvency. On the Effective Date after giving effect to the Transactions,
(a) the fair value of the assets of each Loan Party, at a fair valuation, exceeds its debts and liabilities, subordinated, contingent or otherwise, (b) the present fair saleable value of the property of each Loan Party is greater than the
amount that is required to pay the probable liability of its debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured, (c) each Loan Party is able to pay its debts and
liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured, and (d) each Loan Party does not have unreasonably small capital with which to conduct the business in which it is engaged as such
business is now conducted and is proposed to be conducted following the Effective Date, in each case after giving effect to any rights of indemnification, contribution or subrogation arising among the Subsidiary Loan Parties pursuant to the
Collateral Agreement or by law. 
 SECTION 3.16. Senior Indebtedness. The Obligations constitute
(a) “Senior Debt” under and as defined in the Senior Secured Notes Documents, (b) “Designated Senior Debt” under and as defined in the 10 3/4% Senior Subordinated Notes Documents and (c) “Senior Debt” or a
comparable term under and as defined in (i) the 9 5/8%
Senior Subordinated Notes Documents, (ii) the Physician Notes, (iii) the documentation governing any Additional Physician Notes and (iv) the documentation governing any Additional Subordinated Debt. 
 SECTION 3.17. Reimbursement from Third Party Payors. The accounts receivable generated by Holdings, the Borrower and the Subsidiaries and, to the
knowledge of Holdings, and the Borrower, the accounts receivable generated by the Affiliated Practices have been and will continue to be adjusted to reflect the reimbursement policies required by all applicable Requirements of Law and other Third
Party Payor Arrangements to which Holdings, the Borrower, such Subsidiary or Affiliated Practice is subject, and do not exceed in any material respect amounts the Borrower, such Subsidiary or, to the knowledge the Borrower, such Affiliated Practice
is entitled to receive under any capitation arrangement, fee schedule, discount formula, cost-based reimbursement or other adjustment or limitation to usual charges. All billings generated by Holdings, the Borrower, each Subsidiary and, to the
knowledge of the Borrower, generated by each Affiliated Practice pursuant to any Third Party Payor Arrangements have been made in compliance with all applicable Requirements of Law, except where failure to comply would not, individually or in the
aggregate, be reasonably likely to have a Material Adverse Effect. There has been no intentional or material over-billing or over-collection by the Borrower or any Subsidiary pursuant to any Third Party Payor Arrangements, other than as created by
routine adjustments and disallowances made in the ordinary course of business by the Third Party Payors with respect to such billings. 
 SECTION 3.18. Fraud and Abuse. None of Holdings, the Borrower, any Subsidiary or, to the knowledge of Holdings and the Borrower, any Affiliated Practice, nor any of their respective partners, members, stockholders, officers or
directors, acting on behalf of Holdings, the Borrower, any Subsidiary or, to the knowledge the Borrower, any Affiliated Practice, have engaged on behalf of Holdings, Borrower, any Subsidiary or any Affiliated Practice in any activities that are
prohibited under 42 U.S.C. § 1320a-7, 42 U.S.C. § 1320a-7a, 42 U.S.C. § 1320a-7b, 42 U.S.C. § 1395nn, 31 U.S.C. § 3729 et seq., or the regulations promulgated thereunder, or
related Requirements of Law, or under any similar state law or 

  

 -67- 

 
regulation, or that are prohibited by binding rules of professional conduct, including (a) knowingly and willfully making or causing to be made a false
statement or misrepresentation of a material fact in any application for any benefit or payment, (b) knowingly and willfully making or causing to be made any false statement or misrepresentation of a material fact for use in determining rights
to any benefit or payment, (c) failing to disclose knowledge by a claimant of the occurrence of any event affecting the initial or continued right to any benefit or payment on its own behalf or on behalf of another, with intent to secure such
benefit or payment fraudulently, (d) knowingly and willfully soliciting or receiving any remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind, or offering to pay or receive such
remuneration (i) in return for referring an individual to a Person for the furnishing or arranging for the furnishing of any item or service for which payment may be made, in whole or in part, pursuant to any Third Party Payor Arrangement to
which the foregoing rules and regulations apply or (ii) in return for purchasing, leasing or ordering or arranging for or recommending purchasing, leasing or ordering any good, facility, service, or item for which payment may be made, in whole
or in part, pursuant to any Third Party Payor Arrangements to which the foregoing rules and regulations apply and (e) making any prohibited referral for designated health services, or presenting or causing to be presented a claim or bill to any
individual, third party payor or other entity for designated health services furnished pursuant to a prohibited referral. Neither Holdings, the Borrower nor any Subsidiary shall be considered to be in breach of this Section so long as (a) it or
any Affiliated Practice, as the case may be, shall have taken such actions (including implementation of appropriate internal controls) as may be reasonably necessary to prevent such prohibited actions and (b) such prohibited actions as have
occurred, individually or in the aggregate, are not reasonably likely to have a Material Adverse Effect.

proceeds of the Revolving Loans, Swingline Loans and Letters of Credit will be used only for working capital and for other general corporate purposes, provided that no portion of any drawing under the Commitments may be used to make any

 (b) No part of the proceeds of any Loan and no Letter of Credit will be used, whether directly or indirectly, for any
purpose in violation of any of the Regulations of the Board, including Regulations T, U and X. 
 SECTION 5.12. Additional
Subsidiaries. If any additional wholly-owned domestic Subsidiary is formed or acquired after the Effective Date (or (x) if any Inactive Subsidiary or non-wholly-owned domestic Subsidiary (that is not an Inactive Subsidiary) that is not a
Subsidiary Loan Party ceases to qualify as an Inactive Subsidiary or becomes wholly-owned, as applicable or (y) a Permitted Joint Venture that is not otherwise a Permitted Joint Venture Loan Party becomes a wholly owned Subsidiary of the
Borrower), the Borrower will, promptly, in any event, within 45 days after such Subsidiary is formed or acquired, notify the Collateral Agent and the Lenders (through the Administrative Agent) thereof and promptly, in any event, within 45 days (or
60 days with respect to clauses (e) or (f) of the Collateral and Guarantee Requirement, or such later time with respect to any particular requirements of the Collateral and Guarantee Requirement as consented to by the Collateral Agent in
its reasonable discretion), cause the Collateral and Guarantee Requirement to be satisfied with respect to such Subsidiary (if it is a Subsidiary Loan Party) and with respect to any Equity Interest in or Indebtedness of such Subsidiary owned by or

 -77- 

 
Requirement to be and remain satisfied, all at the expense of the Loan Parties. Each of Holdings and the Borrower also agrees to provide to the Collateral
Agent, from time to time upon reasonable request, evidence reasonably satisfactory to the Administrative Agent as to the perfection and priority of the Liens created or intended to be created by the Security Documents. 
 (b) If any material assets (including any real property or improvements thereto or any interest therein, other than any real property with
a fair value of less than $1,500,000) are acquired by the Borrower or any Subsidiary Loan Party after the Effective Date (other than assets constituting Collateral under the Collateral Agreement that become subject to the Lien in favor of the
Collateral Agreement upon acquisition thereof), the Borrower will notify the Administrative Agent and the Lenders thereof, and, if requested by the Administrative Agent or the Required Lenders, the Borrower will cause such assets to be subjected to
a Lien securing the Obligations and will take, and cause the Subsidiary Loan Parties to take, such actions as shall be necessary or reasonably requested by the Administrative Agent to grant and perfect such Liens, including actions described in
paragraph (a) of this Section, all at the expense of the Loan Parties, provided that the Collateral Agent may, in its reasonable judgment, grant extensions of time for compliance or exceptions with the provisions of this paragraph by any
Loan Party.

Subsidiaries, satisfy customary Company formalities, including (to the maximum extent required under applicable Company laws) the holding of regular board of directors’ and shareholders’ meetings or action by directors or shareholders
without a meeting and the maintenance of Company records. No Loan Party (other than Holdings) shall make any payments to a creditor of Holdings in respect of any liability of Holdings, and no lender account of a Loan Party (other than Holdings)
shall be commingled with any lender account of Holdings. Holdings shall not make any payments to a creditor of any other Person (including another Loan Party) in respect of any liability of such Person (other than pursuant to the Loan Documents) and
no lender account of Holdings shall be commingled with any lender account of any other Person (including another Loan Party). Any financial statements distributed to any creditors of (i) Holdings or (ii) the Borrower or any Subsidiary Loan
Party shall clearly establish or indicate the Company separateness of Holdings. Finally, Holdings shall not take any action, or conduct its affairs in a manner, which is reasonably likely to result in the Company existence of Holdings being ignored,
or in the assets and liabilities of Holdings being substantively consolidated with those of any other such Person (including another Loan Party) in a bankruptcy, reorganization or other insolvency proceeding. 
 (b) The Borrower will ensure that (i) no bank account of any Permitted Joint Venture that is not a Permitted Joint Venture Loan Party
shall be commingled with any bank account of any Loan Party, and (ii) any financial statements distributed to any creditors of any Permitted Joint Venture that is not a Permitted Joint Venture Loan Party shall clearly establish or indicate the
Company separateness of such Permitted Joint Venture from the Loan Parties. 
  

 -78-

such later time as consented to by the Collateral Agent in its reasonable discretion), the Borrower shall cause clauses (e) and (f) of the Collateral and Guarantee Requirement to be satisfied with respect to Mortgaged Property and Deposit
Accounts (other than an Excluded Deposit Account) in existence on the Effective Date.

Succeeding Holdings (including a pledge of all Equity Interests of the Borrower); 
 (iii) Succeeding Holdings shall have
delivered to the Administrative Agent such officer’s certificates, resolutions, opinions and other documents, in each case relating to the Holding Company Restructuring Transaction, as may be reasonably requested by the Administrative Agent;

correct in all material respects on and as of such date of consummation, both immediately before and after giving effect to the consummation of the Holding Company Restructuring Transaction, unless such representations and warranties relate to a
specific earlier date, in which case such representations and warranties shall be true and correct in all material respects as of such earlier date; 
 (v) there shall exist no Default or Event of Default on such date of consummation, both immediately before and after giving effect to the Holding Company Restructuring Transaction; and 
 (vi) the Administrative Agent shall have received an officer’s certificate from a Financial Officer of the Borrower certifying that

expressly provided below, (i) Succeeding Holdings shall become “Holdings” for all purposes of this Agreement and the other Loan Documents and (ii) US Oncology Holdings, Inc. shall be released from the Loan Documents to which it
is a party; provided that, notwithstanding the foregoing, for purposes of Sections 7.01(f), (g), (h), (i), (j) and (k) (and any defined terms as used therein) references to “Holdings” shall be deemed to include both US
Oncology Holdings, Inc. and Succeeding Holdings. 
 SECTION 5.17. Designation of Subsidiaries. 
 For all purposes hereof other than for purposes of calculating the Leverage Ratio, the Board of Directors may designate that any Permitted Joint Venture
is no longer a Subsidiary if: 
 (a) the Permitted Joint Venture to be so designated does not own any Equity Interests or
Indebtedness of, or own or hold any Lien on any Property of, the Borrower or any other Subsidiary, and 
 (b) one of the
following: 
 (1) the Permitted Joint Venture to be so designated has total assets of $1,000 or less, or 
 (2) if such Permitted Joint Venture has total assets greater than $1,000, the Borrower would be permitted under Section 6.08 to make
a Restricted Payment or a Permitted Investment in the amount equal to the Fair Market Value of the Investment in such Permitted Joint Venture. 
 Except as provided in the first sentence of the preceding paragraph (including clauses (a) and (b) thereof), no Permitted Joint Venture that is a Subsidiary may be undesignated as a Subsidiary. In addition, neither the Borrower
nor any Subsidiary shall at any time be directly or indirectly liable for any Indebtedness that provides that the holder thereof may (with the passage of time or notice or both) declare a default thereon or cause the payment thereof to be
accelerated or payable prior to its Stated Maturity upon the occurrence of a default with respect to any Indebtedness, Lien or other obligation of any Permitted Joint Venture that is not designated as a Subsidiary (including any right to take
enforcement action against such Permitted Joint Venture). 
 For all purposes hereof other than for purposes of calculating the Leverage
Ratio, the Board of Directors may designate any Permitted Joint Venture to be a Subsidiary if, immediately after giving pro forma effect to such designation, 
 (x) the Borrower could Incur at least $1.00 of additional Indebtedness pursuant to paragraph (a) of Section 6.01, and

 (y) no Default or Event of Default shall have occurred and be continuing or would result therefrom.

 ARTICLE VIII 
 The Agents 
 SECTION 8.01. The Agents. (a) Each of the Lenders and the Issuing Bank
hereby irrevocably appoints the Administrative Agent as its agent 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 of the Loan Documents,
together with such actions and powers as are reasonably incidental thereto. For purposes of this Article VIII, all references to the Administrative Agent shall be deemed to be references to both the Administrative Agent and the Collateral
Agent. 
 (b) The bank 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 such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other
Affiliate thereof as if it were not the Administrative Agent hereunder. 
 (c) The Administrative Agent shall not have any duties or
obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the duties of the Administrative Agent shall be mechanical and administrative in nature; the Administrative Agent shall
not have by reason of this Agreement or any other Loan Document a fiduciary relationship or other implied duties in respect of any Lender, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not
have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Loan Documents that the Administrative Agent is required to exercise in writing as directed by
the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set forth in the Loan Documents, the Administrative Agent shall
not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to Holdings, the Borrower or any of the Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any
of its Affiliates in any capacity. Nothing in this Agreement or in any other Loan Document, expressed or implied, is intended to or shall be so construed as to impose upon the Administrative Agent any obligations in respect of this Agreement or any
other Loan Document except as expressly set forth herein or therein. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage
of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable
decision). The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by Holdings, the Borrower or a Lender, and 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 any Loan Document, (ii) the contents of any certificate, report or other document delivered
thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or 

  

 -103- 

 
other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any
other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to the Administrative
Agent. 
 (d) 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 believed by it to be genuine and to have been signed or sent 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 be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the 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. If the Administrative Agent requests instructions from the Required Lenders with
respect to any act or action (including failure to act) in connection with this Agreement or any other Loan Document, the Administrative Agent shall be entitled to refrain from such act or taking such action unless and until the Administrative Agent
shall have received instructions from the Required Lenders; and the Administrative Agent shall not incur liability to any Lender by reason of so refraining. Without limiting the foregoing, no Lender shall have any right of action whatsoever against
the Administrative Agent as a result of the Administrative Agent acting or refraining from acting hereunder or under any other Loan Document in accordance with the instructions of the Required Lenders. 
 (e) The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by
the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall
apply to any such sub-agent and to the Related Parties of each Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as
activities as Administrative Agent. 
 (f)(i) Subject to the appointment and acceptance of a successor Administrative Agent as provided in
this paragraph, the Administrative Agent may resign at any time upon 15 days’ prior notice to the Lenders, the Issuing Bank and unless a Default or Event of Default exists, the Borrower. Any such resignation by an Administrative Agent hereunder
shall also constitute its resignation as an Issuing Lender and the Swingline Lender, in which case the resigning Administrative Agent (x) shall not be required to issue any further Letters of Credit after delivering such notice or make any
additional Swingline Loans after delivering such notice hereunder and (y) shall maintain all of its rights as Issuing Lender or Swingline Lender, as the case may be, with respect to any Letters of Credit issued by it, or Swingline Loans made by
it, prior to the date of such resignation. Upon any such resignation, the Required Lenders shall have the right to appoint a successor which successor Administrative Agent shall be consented to by the Borrower at all times other than during the
existence of an Event of Default under Section 7.01(h) or (i). If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 15 days after the retiring Administrative Agent 

  

 -104- 

 
gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor
Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and
become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a
successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and
Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as
Administrative Agent. 
 (ii) The Required Lenders and the Borrower may at any time when the Administrative Agent has become the subject of a
proceeding under any Debtor Relief Law, or had a receiver, conservator, trustee or custodian appointed for it, upon no less than 10 Business Days’ prior notice, replace the Administrative Agent. If the Administrative Agent is replaced pursuant
to the preceding sentence, the Required Lenders shall have the right to appoint a successor which successor Administrative Agent shall be consented to by the Borrower at all times other than during the existence of an Event of Default under
Section 7.01(h) or (i), provided that the successor Administrative Agent shall not be the subject of a proceeding under any Debtor Relief Law, or had a receiver, conservator, trustee or custodian appointed for it and shall succeed to and
become vested with all of the rights, powers, privileges and duties of the replaced Administrative Agent, and the replaced Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Credit Documents.
The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. The provisions of this Article VIII and Section 9.03
shall continue in effect for the benefit of such replaced Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the replaced Administrative Agent was
acting as Administrative Agent. Any such replacement of an Administrative Agent hereunder shall automatically, and with no further action required on the part of the Administrative Agent, constitute the resignation of the Administrative Agent in its
capacity as an Issuing Lender and the Swingline Lender, in which case the replaced Administrative Agent (x) shall not be required to issue any further Letters of Credit or make any additional Swingline Loans hereunder and (y) shall
maintain all of its rights as Issuing Lender or Swingline Lender, as the case may be, with respect to any Letters of Credit issued by it, or Swingline Loans made by it, prior to the date of such replacement. 
 (g) Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, and to the extent it deems appropriate, has
made and shall continue to make (i) its own independent investigation of the financial condition and affairs of Holdings and its Subsidiaries in connection with the making and the continuance of the Loans and the taking or not taking of any
action in connection herewith and (ii) its own appraisal of the creditworthiness of Holdings and its Subsidiaries and, except as expressly provided in this Agreement, the Administrative Agent shall not have any duty or responsibility, either
initially or on a continuing basis, to provide any Lender or the holder of any promissory note in respect of 

  

 -105- 

 
the Obligations with any credit or other information with respect thereto, whether coming into its possession before the making of the Loans or at any time
or times thereafter. The Administrative Agent shall not be responsible to any Lender or the holder of any promissory note in respect of the Obligations for any recitals, statements, information, representations or warranties herein or in any
document, certificate or other writing delivered in connection herewith or for the execution, effectiveness, genuineness, validity, enforceability, perfection, collectibility, priority or sufficiency of this Agreement or any other Loan Document or
the financial condition of Holdings or any of its Subsidiaries or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement or any other Loan Document, or the
financial condition of Holdings or any of its Subsidiaries or the existence or possible existence of any Default or Event of Default. 
 (h)
The Lenders identified in this Agreement as the Syndication Agents and the Documentation Agent shall not have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders. Without
limiting the foregoing, neither any Syndication Agent nor the Documentation Agent shall have or be deemed to have a fiduciary relationship with any Lender. 
 (i) Notwithstanding any other provision of this Agreement or any provision of any other Loan Document, each Arranger is named as such for recognition purposes only, and in its capacity as such shall have no powers,
duties, responsibilities or liabilities with respect to this Agreement or the other Loan Documents or the transactions contemplated hereby and thereby; it being understood and agreed that each Arranger shall be entitled to all indemnification and
reimbursement rights in favor of the Administrative Agent as, and to the extent, provided for under Section 9.03. Without limitation of the foregoing, each Arranger shall not, solely by reason of this Agreement or any other Loan Documents, have
any fiduciary relationship in respect of any Lender or any other Person.

 (b) Notices and other
communications to the Lenders hereunder may be delivered or furnished by electronic communications pursuant to procedures approved by the Administrative Agent, provided that the foregoing shall not apply to notices pursuant to Article II
unless otherwise agreed by the Administrative Agent and the applicable Lender. The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to
procedures approved by it, provided that approval of such procedures may be limited to particular notices or communications. 
 (c) Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to the Administrative Agent (and, in the case of the Administrative Agent, by written notice to the Borrower). All
notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt. 
 SECTION 9.02. Waivers; Amendments. (a) No failure or delay by the Administrative Agent, the Issuing Bank, the Collateral Agent, the Swingline Lender or any Lender in exercising any right or power hereunder
or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further
exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank, the Collateral Agent, the Swingline Lender and the Lenders hereunder and under the other Loan Documents are
cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall
be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or
issuance of a 

  

 -107- 

 
Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender, the Collateral Agent, the
Swingline Lender or the Issuing Bank may have had notice or knowledge of such Default at the time. 
 (b) Except as provided
in Section 2.20 with respect to an Incremental Facility Amendment, neither this Agreement nor any other Loan Document nor any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an
agreement or agreements in writing entered into by Holdings, the Borrower and the Required Lenders or, in the case of any other Loan Document, pursuant to an agreement or agreements in writing entered into by the Administrative Agent and the Loan
Party or Loan Parties that are parties thereto, in each case with the consent of the Required Lenders, provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender,
(ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender directly affected thereby, (iii) postpone the
maturity of any Loan, the required date of reimbursement of any LC Disbursement, or any date for the payment of any interest or fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of
expiration of any Commitment, without the written consent of each Lender directly affected thereby, (iv) change Section 2.18(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written
consent of each Lender directly affected thereby, (v) change any of the provisions of this Section or the percentage set forth in the definition of “Required Lenders” or any other provision of any Loan Document specifying the number
or percentage of Lenders required to waive, amend or modify any rights thereunder or make any determination or grant any consent thereunder, without the written consent of each Lender, (vi) release Holdings or any Subsidiary Loan Party from its
Guarantee under the Collateral Agreement (except as provided in Section 9.16 or in the Collateral Agreement) or limit its liability in respect of such Guarantee, without the written consent of each Lender, or (vii) release all or
substantially all the Collateral from the Liens of the Security Documents (except as provided in Section 9.16 or in the Collateral Agreement), without the written consent of each Lender, provided further that no such agreement
shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, the Issuing Bank or the Swingline Lender without the prior written consent of the Administrative Agent, the Issuing Bank or the Swingline Lender, as
applicable. In connection with any proposed amendment, modification, waiver or termination (a “Proposed Change”) requiring the consent of all affected Lenders, if (i) the consent of the Supermajority Lenders to such Proposed
Change is obtained, but the consent to such Proposed Change of other Lenders whose consent is required is not obtained (any such Lender whose consent is not obtained as described in this Section 9.02(b) being referred to as a
“Non-Consenting Lender”) or (ii) any Lender becomes a Defaulting Lender, then, so long as the Lender that is acting as the Administrative Agent is not a Non-Consenting Lender or Defaulting Lender, at the Borrower’s
request, any assignee that is acceptable to the Administrative Agent shall have the right, with the Administrative Agent’s consent, to purchase from such Non-Consenting Lender or Defaulting Lender, and such Non-Consenting Lender or Defaulting
Lender agrees that it shall, upon the Borrower’s request, sell and assign to 

  

 -108- 

 
such assignee, at no expense to such Non-Consenting Lender or Defaulting Lender, all the Commitments and Exposure of such Non-Consenting Lender or Defaulting
Lender for an amount equal to the principal balance of all Revolving Loans (and funded participations in Swingline Loans and unreimbursed LC Disbursements) held by such Non-Consenting Lender or Defaulting Lender and all accrued interest and fees
with respect thereto through the date of sale (including amounts under Section 2.15, 2.16 and 2.17), such purchase and sale to be consummated pursuant to an executed Assignment and Assumption in accordance with Section 9.04(b) (which
Assignment and Assumption need not be signed by such Non-Consenting Lender or Defaulting Lender). 
 SECTION 9.03. Expenses; Indemnity;
Damage Waiver. (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Agents and their respective Affiliates, including the reasonable fees, charges and disbursements of counsel for the Agents, in
connection with the syndication of the credit facilities provided for herein, the preparation and administration of the Loan Documents or any amendments, modifications or waivers of the provisions thereof (whether or not the transactions
contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment
thereunder and (iii) all reasonable out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the reasonable fees, charges and disbursements of any counsel for the Administrative Agent, the Issuing
Bank or any Lender, in connection with any Back-Stop Arrangements entered into by such Persons and the enforcement or protection of its rights in connection with the Loan Documents, including its rights under this Section, or in connection with the
Loans made or Letters of Credit issued hereunder, including all such reasonable out-of-pocket expenses, incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit. Additionally, the Borrower agrees to
reimburse the Administrative Agent and the Collateral Agent for all reasonable third party administrative and examination expenses relating to the Collateral securing the Obligations (including, without limitation, the one-time examination, auditing
and consulting services provided by FTI, Inc. in connection with the preparation of this Agreement). 
 (b) The Borrower shall
indemnify the Administrative Agent, the Issuing Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and
all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of
(i) the execution or delivery of any Loan Document or any other agreement or instrument contemplated hereby, the performance by the parties to the Loan Documents of their respective obligations thereunder or the consummation of the Transactions
or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented
in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or Release of Hazardous Materials on or from any Mortgaged Property or any other property currently or formerly
owned or operated by the Borrower or any of its Subsidiaries, or any actual or alleged Environmental Liability related in any 

  

 -109- 

 
way to the Borrower or any of its Subsidiaries or their respective properties or operations, 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 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, damages, liabilities or related expenses are determined by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Indemnitee. 
 (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent, the Issuing Bank or the
Swingline Lender under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent, the Issuing Bank or the Swingline Lender, as applicable, such Lender’s pro rata share (determined as of the
time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount, provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as applicable, was incurred by or
asserted against the Administrative Agent, the Issuing Bank or the Swingline Lender in its capacity as such. For purposes hereof, a Lender’s “pro rata share” shall be determined based upon its share of the aggregate Exposures and
unused Commitments at the time. 
 (d) To the extent permitted by applicable law, neither Holdings nor the Borrower shall
assert, and each hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of,
this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof. 
 (e) All amounts due under this Section shall be payable not later than three Business Days after written demand therefor. 
 SECTION 9.04. Successors and Assigns. (a) 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
(including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and
any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. 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 (including any Affiliate of the Issuing Bank that issues any Letter of Credit),
Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right,
remedy or claim under or by reason of this Agreement. 
 (b) (i) Subject to the conditions set forth in
paragraph (b)(ii) below, any Lender may assign to one or more assignees (other than to Holdings, the Borrower or 

  

 -110- 

 
any of their Affiliates) 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) with the prior written consent (such consent not to be unreasonably withheld or delayed) of: 
 (1) the
Borrower, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund (as defined below) or, if an Event of Default has occurred and is continuing, any other assignee;
and 
 (2) the Administrative Agent; 
 (3) the Issuing Bank; and 
 (4) the Swingline Lender. 
 (ii) Assignments shall be subject to the following conditions:

 (1) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining
amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or 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) shall not be less than $5,000,000, unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default has
occurred and is continuing; 
 (2) 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, provided that this clause shall not be construed to prohibit assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of such
assigning Lender’s Commitments or Loans; 
 (3) 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; and 
 (4) the
assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. 
 For purposes of this
Section 9.04(b), the terms “Approved Fund” and “CLO” have the following meanings: 
 “Approved
Fund” means (a) a CLO and (b) with respect to any Lender that is a fund which invests in bank loans and similar extensions of credit, any other fund that invests in bank loans and similar extensions of credit and is managed by the
same investment advisor as such Lender or by an Affiliate of such investment advisor. 
  

 -111- 

 “CLO” means any entity (whether a corporation, partnership, trust or otherwise) that is
engaged in making, purchasing, holding or otherwise investing in bank loans and similar extensions of credit in the ordinary course and is administered or managed by a Lender or an Affiliate of such Lender. 
 (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date
specified in each Assignment and Assumption the assignee thereunder shall be a party hereto 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 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 2.15, 2.16, 2.17 and 9.03). Any assignment or transfer by a Lender of rights
or obligations under this Agreement that does not comply with this Section 9.04 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 (c) of
this Section. 
 (iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of
its offices 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 Commitment of, and principal amount of the Loans and LC Disbursements owing to, each
Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Banks and the Lenders may treat each Person whose name
is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Banks and any
Lender, at any reasonable time and from time to time upon reasonable prior notice. 
 (v) Upon its receipt of a duly completed
Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in
paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the
Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. 
 (c) (i) Any Lender may, without the consent of the Borrower, the Administrative Agent, the Issuing Banks or the Swingline Lender, sell participations to one or more banks or other entities (a
“Participant”) in all or a portion of such Lender’s 

  

 -112- 

 
rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it), provided that (A) such
Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, the
Issuing Banks and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells 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 Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this
Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this
Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.18(c) as though it were a
Lender. 
 (ii) A Participant shall not be entitled to receive any greater payment under Section 2.15 or 2.17 than the
applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that
would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to
comply with Section 2.17(e) as though it were a Lender. 
 (iii) Any Lender may at any time pledge, assign or grant a
security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge, assignment or grant to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such
pledge, assignment or grant of a security interest, provided that no such pledge, assignment or grant of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such
Lender as a party hereto. 
 SECTION 9.05. Survival. All covenants, agreements, representations and warranties made by the Loan
Parties in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of the Loan Documents and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative
Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the 

  

 -113- 

 
time any credit is 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 or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.15, 2.16, 2.17 and 9.03 and
Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the
termination of this Agreement or any provision hereof. 
 SECTION 9.06. Counterparts; Integration; Effectiveness. This Agreement may
be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, 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 4.01, 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 which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an
executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. 
 SECTION 9.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity,
illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other
jurisdiction. 
 SECTION 9.08. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of
its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other
obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The applicable Lender shall notify the Borrower and the Administrative Agent of such set-off or application, provided
that any failure to give or any delay in giving such notice shall not affect the validity of any such set-off or application under this Section. The rights of each Lender under this Section are in addition to other rights and remedies (including
other rights of setoff) which such Lender may have. 
 SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of Process.
(a) This Agreement shall be construed in accordance with and governed by the law of the State of New York. 
  

 -114- 

 (b) Each of Holdings and the Borrower hereby irrevocably and unconditionally submits, for
