damages contemplated by this Section 2.7 shall be the sole and exclusive remedy for Seller’s breach of Section 5.9(b)(i) and Section 5.9(c). The liquidated damages so paid will be treated as a reduction in
the purchase price and Seller will irrevocably forfeit the right to any such amount payable and shall, if requested, unconditionally consent in writing to the release of funds so owing to Buyer from the Escrow Account. Buyer shall cause all of the
Funds in excess of the Escrow Deposit (each as defined in the Escrow Agreement) to be released to Seller promptly upon termination of the Escrow Agreement in accordance with its terms. 
  

 18 

 (e) The Parties hereby acknowledge and agree that (i) the amounts described in this
Section 2.7 shall constitute liquidated damages because the potential injury to Buyer resulting from Seller’s potential breach of Section 5.9(b)(i) or Section 5.9(c) is uncertain and difficult to quantify,
(ii) the amount of such liquidated damages is reasonable and considers (A) the actual or anticipated harm that could be caused by Seller’s potential breach of Section 5.9(b)(i) or Section 5.9(c), (B) the
difficulty of proving the loss arising from any such potential breach, and (C) the difficulty of finding another, adequate remedy at law, and (iii) such liquidated damages are structured to function as damages resulting from Seller’s
potential breach of Section 5.9(b)(i) or Section 5.9(c) and not as a penalty.

partnership duly organized, validly existing, and in good standing under the laws of the State of Delaware and has all requisite limited partnership power and authority to conduct its business as it is now being conducted and to own, lease, and
operate its property and assets except where the failure to be so organized, existing, and in good standing or to have such power or authority would not, in the aggregate, either (a) have a material adverse effect on the business, results of
operations, assets, or financial condition of Buyer or (b) impair, hinder, or adversely affect the ability of Buyer to perform material obligations under this Agreement or to consummate the transactions contemplated hereby (either of such
effects, a “Buyer Material Adverse Effect”). 
 4.2 Authority. Buyer has all requisite limited partnership authority
and power to execute and deliver the Transaction Documents and to consummate the transactions contemplated by the Transaction Documents. The execution and delivery of the Transaction Documents and the consummation of the transactions contemplated by
the Transaction Documents have been duly and validly authorized by all required action on the part of Buyer and no other proceedings on the part of Buyer are necessary to authorize the Transaction Documents or to consummate the transactions
contemplated by the Transaction Documents. The Transaction Documents have been duly and validly executed and delivered by Buyer and, assuming the Transaction Documents have been duly authorized, executed, and delivered by Seller, the Transaction
Documents shall constitute a valid and binding agreement of Buyer, 

  

 32 

 
enforceable against Buyer in accordance with their terms, except as limited by applicable bankruptcy, insolvency, reorganization, moratorium, or other
similar Laws now or hereafter in effect relating to or affecting creditors’ rights generally, including the effect of statutory and other Laws regarding fraudulent conveyances and preferential transfers, and subject to the limitations imposed
by general equitable principles and considerations of public policy. 
 4.3 No Conflicts. Neither the execution and delivery of the
Transaction Documents by Buyer nor the consummation of the transactions contemplated hereby or thereby by Buyer will (a) violate any provision of the limited partnership agreement (or other comparable governing documents) of Buyer,
(b) require any material consent, waiver, or approval of any Governmental Authority, except for material consents and approvals to be made and obtained before the Closing and those which have been made and obtained, (c) result in any
material violation or breach of, or constitute (with or without notice or lapse of time or both) a material default (or give rise to any right of termination, cancellation, acceleration, or any obligation to repay) under, any of the terms,
conditions, or provisions of any indenture, mortgage, note, bond, encumbrance, license, contract, lease, franchise, permit, agreement, or other instrument or obligation to which Buyer is a party or by which Buyer or any of its properties or assets
may be bound, or (d) violate in any material respect any order, writ, judgment, injunction, decree, statute, ordinance, rule, or regulation of any Governmental Authority applicable to Buyer or by which any of its properties or assets may be
bound. 
 4.4 Litigation. There is no action, inquiry, audit, investigation, notice, claim, suit, review, or proceeding, pending or,

upon any distribution or resale of the Equity Interests under the Securities Act and other applicable federal and state securities laws, and the rules and regulations promulgated thereunder, and Buyer agrees that it will refrain from transferring,

Buyer and Seller.

the Buyer Representatives as a result of, or in connection with any site visits or inspections of the assets or properties of any Seller Indemnified Party. THE INDEMNIFICATION PROVISIONS IN THIS SECTION 5.8 SHALL BE ENFORCEABLE REGARDLESS OF

UPON THE PERSON SEEKING INDEMNIFICATION.

the date that is 5 days prior to the due date for payment of any Taxes due from any member of the NOARK Group for a Prior Tax Period or a Straddle Tax Period, Seller shall remit to Buyer an amount in cash equal to the excess (if any) of (i) the

accruing in a Post-Closing Tax Period. 
 (c) Straddle Period Taxes. Liability for Taxes for any Straddle Tax Period
shall be apportioned as follows: (i) property and similar ad valorem Taxes shall be apportioned on a ratable daily basis; and (ii) all other Taxes, including income Taxes, shall be apportioned based on an interim closing of the books of
each appropriate member of the NOARK Group as of the end of the Closing Date. Any franchise Tax paid or payable with respect to any member of the NOARK Group shall be allocated to the Tax period during which the gross receipts, income, operations,
assets or capital comprising the base of such Tax is measured, regardless of whether the right to do business for another period is obtained by the payment of such franchise Tax. 
 (d) Information Sharing; Disputes over Tax Provisions. Buyer and Seller shall each provide the other with all information
reasonably requested and necessary to prepare a Tax Return or conduct an audit or contest with respect to Taxes. The Accountant shall resolve any dispute between Buyer and Seller over the application of this Section 5.10 substantially in
the manner described in Section 2.4(e). 
 (e) Tax Sharing Agreements. Any Tax sharing agreement between
any member of the NOARK Group and Seller or any of Seller’s Affiliates (other than a member of the NOARK Group) shall be terminated as of the Closing Date and shall have no further effect with respect to any Pre-Closing Tax Period or

 42

replace, not later than 30 days after the Closing Date, all Seller’s Security (listed in Schedule 5.11 with new letters of credit, guaranties, or other security for post-Closing Date business operations of the NOARK Group, and
concurrently therewith in each case to secure a release of the corresponding Seller’s Security. Buyer agrees to and shall reimburse Seller, its issuing banks and the respective guarantors of each member of the NOARK Group upon demand for all
amounts paid and reasonable out-of-pocket expenses incurred under or in connection with any demand upon any of Seller’s Security related to post-Closing Date transactions, and shall reimburse Seller any additional costs incurred after Closing
upon demand the cost of providing Seller’s Security for the period beginning on the Closing Date and continuing until release of all of Seller’s Security. 
 5.12 Marks. 
 (a) Buyer shall obtain no right, title, interest, license or any other
right whatsoever to use the words “Atlas” or “Atlas Pipeline” or any trademarks containing or comprising the foregoing, or any trademark confusingly similar thereto or dilutive thereof (collectively, the “Seller
Marks”). From and after the Closing, Buyer agrees that it will cause the NOARK Group to cease using the Seller Marks in any manner, directly or indirectly, except for such limited uses as cannot be promptly terminated (e.g., signage,
e-mail addresses, and as a referral or pointer to the acquired website) or uses associated with the provision of transition services (e.g. pipeline and meter station signage that contain the emergency phone number for Atlas Gas Control), and
to cease such limited usage of the Seller Marks as promptly as possible after the Closing and in any event within 90 days following the Closing Date or the date at which time the applicable transition service is terminated, and remove, strike over
or otherwise obliterate all Seller Marks from all assets and all other materials owned, possessed or used by the NOARK Group. 
 (b) Seller agrees that it and its Affiliates shall (i) as promptly as possible after the Closing and in any event within 90 days following the Closing Date, cease to make any use of the names “NOARK,” “Ozark Gas

(ii) immediately after the Closing, cease to hold itself out as having an affiliation with the NOARK Group except for uses associated with the provision of transition services (e.g. Gas Control services). In furtherance thereof, as
promptly as possible after the Closing and in any event within 90 days following the Closing Date, Seller shall remove, strike over or otherwise obliterate and shall cause its Affiliates to remove, strike over or otherwise obliterate all Buyer Marks
from all assets and all other materials owned, possessed or used by Seller and its Affiliates. 
 (c) The Parties agree,
because damages would be an inadequate remedy, that a Party seeking to enforce this Section 5.12 shall be entitled to seek specific performance and injunctive relief as remedies for any breach thereof in addition to other remedies
available at law or in equity. This covenant shall survive indefinitely without limitation as to time.

relating to the business or operations of the NOARK Group (the “Ozark Documents”) in existence on the day of Closing and not already in the possession of the NOARK Group or Buyer, provided however, that Seller may retain (but
shall preserve and keep in accordance with the following sentence) all Ozark Documents that do not exclusively or primarily relate to the Business or the NOARK Group. Seller and its respective Affiliates shall preserve and keep all Ozark Documents
not delivered to Buyer on or before the Closing Date for a period of at least seven years after the Closing Date (the “Retention Period”). After the expiration of the Retention Period, before Seller shall dispose of any Ozark
Documents, Seller shall give Buyer at least 90 days’ prior notice to such effect, and Buyer shall be given an opportunity, at its cost and expense, to remove and retain all or any Ozark Documents as Buyer may select. Seller shall provide to
Buyer, at no cost or expense to Buyer, full access to the Ozark Documents as remain in Seller’s possession and full access to the properties and employees of Seller in connection with matters relating to the business or operations of the Ozark
Gas Companies on or before the Closing Date and any disputes relating to this Agreement. 
 (b) Buyer shall preserve and keep
a copy of the Ozark Documents that are or come into Buyer’s possession for the Retention Period. After the expiration of the Retention Period, before Buyer shall dispose of any Ozark Documents, Buyer shall give Seller at least 90 days’
prior notice to such effect, and Seller shall be given an opportunity, at its cost and expense, to remove and retain all or any Ozark Documents as Seller may select. Buyer shall provide to Seller, at no cost or expense to Seller, full access to the
Ozark Documents as remain in Buyer’s possession and full access to the properties and employees of Buyer and the members of the NOARK Group in connection with matters relating to the business or operations of the NOARK Group on or before the
Closing Date and any disputes relating to this Agreement. 
 5.14 Confidentiality and Use of Information. For 2 years after Closing,
except as required by any applicable Law, Governmental Authority, or applicable stock exchange rule, Seller and its Affiliates shall not directly or indirectly, disclose to any Person or use, any information (a) contained in the Ozark
Documents; (b) not then in the public domain or generally known in the industry; or (c) acquired on a confidential basis from a source who, to the Knowledge of Seller, was bound by an agreement with Buyer or any member of the NOARK Group
to keep such information confidential or otherwise prohibited from transmitting the information to Seller or any of its Affiliates by a contractual, legal or fiduciary obligation, in each case, acquired prior to the Closing Date, and relating to the
Business (and not any other business of Seller) or the NOARK Group (collectively, the “Buyer Protected Information”), provided however, that Seller and its Affiliates may use the Ozark Documents and Buyer Protected
Information to the extent necessary, in connection with any dispute or claim, tax matter relating to Seller’s prior ownership of the NOARK Group, or the transactions contemplated by the Transaction Documents. 
  

 44 

 5.15 No Solicitation of Transactions. 
 (a) At any time subsequent to the date hereof, and prior to the earlier to occur of the Closing or the termination of this Agreement under
Section 8.1, Seller, its Affiliates and the NOARK Group shall not, directly or indirectly, through any officer, director, agent or employee of, or any investment banker, financial advisor, attorney, accountant or other representative
retained by, Seller, the NOARK Group or any of their respective Affiliates (each a “Seller Party”) (i) solicit, initiate, seek or encourage (including by way of furnishing information or assistance) or take other action to
facilitate any inquiries or the submission of any proposal which constitutes or may reasonably be expected to lead to, an Acquisition Proposal from any person other than Buyer (a “Third Party”), or (ii) engage in any
discussions or negotiations relating thereto or in furtherance thereof or accept any Acquisition Proposal. Seller, any member of the NOARK Group and their respective Affiliates shall notify Buyer if a written Acquisition Proposal has been received.
Seller, the NOARK Group and their respective Affiliates agree not to release any Third Party from, or waive any provision of, any confidentiality agreement relating to the sale of the Business, or any member of the NOARK Group. 
 (b) Upon execution by Seller of this Agreement, Seller and its Affiliates will terminate any solicitations, encouragement, activities,
discussions and negotiations with any Person other than Buyer conducted heretofore by Seller, its Affiliates or the NOARK Group with respect to any Acquisition Proposal until the earlier of Closing or termination of this Agreement pursuant to
Section 8.1. 
 5.16 Notifications and Business Permits. Buyer shall provide all notices and otherwise take all actions
required to transfer or reissue any Business Permits, including those required under Environmental Laws, as a result of or in furtherance of the transactions contemplated by this Agreement. Seller shall use commercially reasonable efforts to
cooperate with Buyer to provide information necessary to apply for such Business Permits. 
 5.17 Employee Matters. 
 (a) Prior to the Closing Date, Seller shall provide Buyer with an updated list of the Subject Employees within 5 Business Days of the date
upon which any change therein has occurred. On or before the Closing Date, Buyer or an Affiliate of Buyer (such entity that makes employment offers being the “Buyer Employer”) shall offer employment, which shall be contingent upon
the occurrence of the Closing and the satisfaction of Buyer Employer’s pre-hiring requirements, to each Subject Employee that Buyer Employer desires to employ. Buyer shall inform Seller in writing of the identity of each Subject Employee to
whom Buyer Employer has made an offer of employment (collectively, the “Offered Employees”). Each offer of employment to an Offered Employee shall be on terms and conditions determined by Buyer Employer in its sole discretion that
are consistent with the provisions of this Section 5.17. As used in this Agreement, the term “Continuing Employee” means each individual who accepts an offer of employment from Buyer Employer as provided in the preceding
provisions of this paragraph and who actually becomes employed by Buyer Employer in accordance with such offer. The “Hire Date” for each Continuing Employee shall be the Closing Date, 

  

 45 

 
except with respect to those individuals to whom employment offers are made and (i) who are not Actively Employed as of the Closing Date, in which case
the Hire Date shall be the date upon which such individual is able to and does commence active duty with Buyer Employer, or (ii) with respect to whom Buyer and Seller have agreed will have a later Hire Date. “Actively Employed”
shall mean that the individual is an employee of an Affiliate of Seller on the day immediately prior to the Closing Date and on the Closing Date such individual is performing his regular occupation for his employer (either at such employer’s
usual places of business or at some location to which such employer’s business requires the employee to travel). It is understood and agreed that any Continuing Employee who is not Actively Employed as of the Closing Date shall not be eligible
to participate in any Buyer Employer Employee Plan at any time prior to the date said Continuing Employee is in active duty with the Buyer Employer. 
 (b) Buyer Employer’s offer of employment to the Offered Employees shall (i) be at an annual salary or hourly wage rate that is not less than the annual salary or hourly wage rate that the Offered Employee
was receiving immediately prior to the date of this Agreement, in accordance with the information contained in Schedule 3.21(f), and (ii) permit them, if they become Continuing Employees, to be eligible to participate in Employee Plans
which are offered to similarly situated employees of Buyer Employer. Buyer Employer shall also provide severance benefits to any Continuing Employee who is terminated from employment by Buyer Employer without cause within 2 years following Closing.
Such severance benefits shall be provided in exchange for a release of employment claims by such Continuing Employee and shall provide for payment of severance in the amount equal to (i) one week’s base pay for each year of service for a
period up to 9 years’ service; plus (ii) two weeks’ base pay for each year of service in excess of 9 years’ service; plus (iii) one week’s base pay for each $10,000 of base salary, which total severance amount shall not
be less than 12 weeks’ base pay nor more than 104 weeks’ base pay; and shall further provide for 6 months’ fully subsidized medical and dental COBRA coverage to the extent such coverage is elected by such Continuing Employee and shall
also provide outplacement assistance and up to $2500 of tuition reimbursement assistance, both in accordance with Buyer Employer’s policies and procedures; provided, however, that such severance benefits shall not be payable to
any Continuing Employee who has an employment or other agreement with Buyer, Seller, a member of the NOARK Group or any of their respective Affiliates, which provides for the payment of monies or other benefits upon termination of employment;
provided, further, that Buyer Employer shall be permitted to document this requirement to provide severance benefits in a manner that satisfies the requirements of Section 409A of the Code (including specifying time of payment provisions
or limitations on the amount and timing of the provision of benefits to exempt any benefits required to be provided hereunder from being subject to the requirements of Section 409A of the Code). Additionally, Buyer shall waive (or cause to be
waived) any pre-existing condition limitation and eligibility waiting period under the group health plans (other than for purposes of retiree medical and dental benefits) provided by Buyer Employer to the Continuing Employees following Closing to
the extent such exclusions and limitations were not imposed with respect to such Continuing Employee under the corresponding Seller Plans. From and after the applicable Hire Date, for purposes of (1) eligibility and benefit determination under
the vacation and sick leave policies that are maintained after 

  

 46 

 
such date by the Buyer Employer and (2) determining the years of service of a Continuing Employee for purposes of calculating the severance benefit, if
any, to which such Continuing Employee may become entitled pursuant to the preceding provisions of this Section 5.17(b), Buyer shall cause the Buyer Employer to recognize each Continuing Employee’s years of service
with Seller and its Affiliates based on such Continuing Employee’s date of hire as set forth in Schedule 3.21(f). As applied to the Continuing Employees, the current Buyer Employer’s retirement savings plan
(401(k)) will not impose a waiting period for enrollment and will provide for 100% vesting with respect to employer matching contributions. 
 (c) Between the date hereof and the Closing Date, Seller and its Affiliates shall provide Buyer and its Affiliates, as applicable, with reasonable access to the Subject Employees and shall not take any action to
discourage any Offered Employee from accepting an offer of employment from Buyer Employer. 
 (d) On or before the second
customary payroll of an Affiliate of Seller occurring after each Continuing Employee’s Hire Date, Seller and Seller’s Affiliates (other than the NOARK Group), as applicable, shall pay the Continuing Employee all amounts owed to the
Continuing Employee for accrued but unused paid-time-off (PTO) under the Seller Plans. 
 (e) Seller shall provide, or shall
cause an Affiliate of Seller (other than the NOARK Group) to provide, COBRA continuation coverage (within the meaning of Section 4980B of the Code and the Treasury regulations thereunder) to all individuals who are M & A qualified
beneficiaries (within the meaning assigned to such term under Q&A-4 of Treasury regulation section 54.4980B-9) with respect to the transactions contemplated by this Agreement for the duration of the period to which such individuals are entitled
to such coverage. Seller shall take any and all necessary actions to ensure that Buyer, the NOARK Group and their respective Affiliates are not required to provide such continuation coverage to any such individual at any time. 
 (f) Other than the Change of Control Agreements, Buyer and its Affiliates shall not, and from and after the Closing Date, the NOARK Group
shall not, have any responsibility or liability with respect to the Seller Plans. This Section 5.17 is not intended to confer upon any Subject Employee, Offered Employee or Continuing Employee any rights or remedies hereunder. Nothing in
this Agreement shall require or be construed or interpreted as requiring Buyer, Buyer Employer or any of their Affiliates to continue the employment of any of the Continuing Employees following the Closing Date, or to prevent Buyer, Buyer Employer
or any of their Affiliates from changing the terms and conditions of employment (including compensation and benefits) of any of the Continuing Employees following the Closing Date. As of each Continuing Employee’s Hire Date, such Continuing
Employee will be an “employee at will,” and, accordingly, as of such date, the employment of such Continuing Employee may be terminated by Buyer Employer or its Affiliates without cause or prior notice. 
  

 47 

 5.18 Non-Competition; Non-Solicitation. 
 (a) Unless otherwise consented to in writing by Buyer, Seller agrees that during the Restricted Period, neither Seller nor any of its
Affiliates will, either directly or indirectly, on its own behalf or in the service or on behalf of others, engage in any Competing Business, including: (i) act as an agent, representative, consultant, manager, or operator of a Competing
Business, including provide managerial, supervisory, administrative, financial or consulting services or assistance to any Competing Business; (ii) participate in any Competing Business as an owner, investor, member, partner, limited partner,

or identified prospective client or customer of the NOARK Group, or independent contractor, client or customer of the NOARK Group; provided, however, nothing in this Section 5.18 shall be deemed to prohibit Seller or any of its
Affiliates from (i) owning, directly or indirectly, less than five percent (5%) of any class of securities issued by a Person, directly or indirectly, engaged in any Competing Business which securities are publicly traded; or
(ii) acquiring any assets or business in which the portion thereof constituting a Competing Business does not represent more than 25% of the total net book value of such assets or business. 
 (b) Unless otherwise consented to in writing by Buyer, Seller agrees that during the Restricted Period, neither Seller nor any of its
Affiliates will, either directly or indirectly, on its own behalf or in the service or on behalf of others: (i) solicit, divert or appropriate to or for a Competing Business (A) any Person that is a customer or client of the Business at or
after Closing, or (B) any Person that was a customer or client of the Business during the two (2) year period preceding the Closing; or (ii) attempt to solicit, divert or appropriate to or for a Competing Business any such Person.

 (c) Unless otherwise consented to in writing by Buyer, Seller agrees that during the Restricted Period, neither Seller nor
any of its Affiliates will, either directly or indirectly, on its own behalf or in the service or on behalf of others: (i) solicit, divert or hire away to or for itself, an Affiliate of Seller or a Competing Business any Continuing Employee; or
(ii) attempt to solicit, divert or hire away to or for itself, an Affiliate of Seller or a Competing Business any Continuing Employee, except if the employment of such Continuing Employee has been terminated by Buyer, or any of its Affiliates
after Closing, prior to commencement of employment discussions between such Continuing Employee and Seller or any of its Affiliates, provided that the foregoing shall not prohibit bona fide public non-targeted solicitations for
employees by Seller (whether posted on a public site on the Internet or in a newspaper, magazine or other publication of general circulation). 
 5.19 Claims Made Tail Policy. Upon Buyer’s written request, Seller shall obtain and maintain, at Buyer’s cost, director and officer “claims made” insurance policies covering the Business as of the date hereof but
solely with respect to acts or events occurring prior to the Closing for the benefit of the NOARK Group and their respective directors and officers, and Seller shall make reasonable attempts to have such policies in place as of the Closing and shall

  

 48 

 
keep such policies in place until the sixth anniversary date of the Closing; provided, however, that at any time after Closing but prior to the
sixth anniversary date of the Closing Date, Buyer may elect to terminate Seller’s obligation to maintain such director and officer “claims made” insurance policies by delivering written notice of this election to Seller, and upon
receipt of such written notice from Buyer, Seller shall promptly terminate such director and officer “claims made” insurance policies and remit to Buyer any premium refund received by Seller. 
 5.20 NES. Prior to Closing, Seller shall cause NOARK to divest or otherwise transfer all of its equity interests in NES to either Seller or one of
Seller’s Affiliates (other than any member of the NOARK Group) without any indemnification or other residual liability on the part of any of the NOARK Group. For the avoidance of doubt, neither NES nor the equity interests in NES shall be
considered part of the NOARK Group or the Business at any time.

Indemnified Parties against any and all Damages arising, directly or indirectly, from (i) NOARK’s ownership of NES or otherwise arising from NES or its business, operations, activities, assets or liabilities or (ii) any member of the
NOARK Group having been a member of an affiliated, consolidated, combined or unitary group (other than the NOARK Group) for any period prior to Closing, including pursuant to Treasury Regulations 1.1502-6 or any analogous or similar state, local or
foreign law. 
 7.4 Indemnification of Seller Indemnified Parties. Following the Closing, Buyer will indemnify, defend, and hold
harmless Seller and its partners, officers, directors, employees, Subsidiaries and Affiliates (the “Seller Indemnified Parties”) from and against any and all Damages arising, directly or indirectly, from or in connection with
(i) any failure of any representation or warranty made by Buyer in this Agreement or any closing certificate delivered pursuant to this Agreement to be true and correct as of the Closing (as if made anew at and as of the Closing), and
(ii) the breach of any covenant or agreement made or to be performed by Buyer pursuant to this Agreement. 
 7.5 Procedures.

 (a) If a Buyer Indemnified Party or Seller Indemnified Party that is entitled to seek indemnification under
Section 7.3 (an “Indemnified Party”) has a claim for indemnification under this Article VII, other than a claim for indemnification that involves a Third Party Claim, it shall give written notice (a “Claim
Notice”) to Seller or Buyer, as applicable (in each case, the “Indemnifying Party”), which notice shall describe in reasonable detail to the extent then known the nature of such claim and the factual basis and circumstances
surrounding the same and set forth an estimate of the amount of Damages attributable to such claim. The Indemnifying Party shall, within 30 days after its receipt of a Claim Notice, notify the Indemnified Party in writing as to 

  

 52 

 
whether the Indemnifying Party admits or disputes the claim described in the Claim Notice. If the Indemnifying Party gives written notice that it admits the
indemnification claim described in the Claim Notice, then the Indemnified Party shall be entitled to indemnification pursuant to the provisions of this Article VII, and subject to the limitations hereof, with respect to the estimated amount
of Damages stated in the Claim Notice. If the Indemnifying Party notifies the Indemnified Party in writing that it disputes the claim for indemnification, or that it admits the entitlement of the Indemnified Party to indemnification under this
Article VII with respect thereto but disputes the amount of the Damages in connection therewith, then in either of such cases the indemnification claim described in the Claim Notice shall be a disputed indemnification claim that must be
resolved by settlement between the Indemnified Party and the Indemnifying Party or by proceedings commenced in an appropriate court of competent jurisdiction by either the Indemnifying Party or the Indemnified Party or by any other mutually
agreeable method. 
 (b) If an Indemnified Party receives notice of the assertion or commencement of any claim, demand,
action, suit or proceeding made or brought by any Person who or which is not a Party to this Agreement (a “Third Party Claim”) against such Indemnified Party with respect to which the Person against whom or which such
indemnification is being sought is obligated to provide indemnification under this Agreement, the Indemnified Party will give the Indemnifying Party prompt written notice thereof, but in any event not later than 10 Business Days after receipt of
such written notice of such Third Party Claim (the “Third Party Claim Notice”). Such notice by the Indemnified Party will describe the Third Party Claim in reasonable detail, will include copies of all available material written
evidence thereof, and will indicate the estimated amount, if reasonably practicable, of the Damages that have been or may be sustained by the Indemnified Party. Within 15 days after receipt of the Third Party Claim Notice, the Indemnifying Party
shall notify the Indemnified Party in writing that Indemnifying Party either (i) disputes the right of the Indemnified Party to indemnification under this Article VII with respect to the Third Party Claim or (ii) admits the right of
the Indemnified Party to indemnification under this Article VII with respect to Damages arising in connection with the Third Party Claim. The failure of the Indemnifying Party to respond to the Indemnified Party within such 15-day period
after receipt of a Third Party Claim Notice shall be deemed to constitute a response by the Indemnifying Party that it disputes the right of such Indemnified Party to indemnification under this Article VII with respect to that Third Party
Claim. 
 (c) If the Indemnifying Party admits in writing that the Indemnified Party is entitled to indemnification under this
Article VII with respect to a Third Party Claim, then in such event (i) the Indemnifying Party shall diligently defend the Third Party Claim with counsel approved by the Indemnified Party (which approval shall not be unreasonably
withheld, conditioned or delayed) and (ii) the Indemnifying Party shall not enter into any settlement of the Third Party Claim unless such settlement is approved in writing by the Indemnified Party (which approval shall not be unreasonably
withheld, conditioned or delayed); provided, however, that with respect to any claim related to Taxes, such claim shall be defended by the Person who has legal liability for the claim subject to the control of the Indemnifying Party and the
approval rights of 

  

 53 

 
clause (ii). The costs and expenses of such defense shall be payable by the Indemnifying Party. If, however, (i) the Indemnifying Party at any time
fails to so conduct the defense of the Third Party Claim or (ii) the Indemnified Party, (A) determines in good faith that there is a reasonable probability that a proceeding may adversely affect it other than as a result of monetary
damages for which it would be entitled to full indemnification under this Agreement or (B) upon consultation with counsel has reasonably determined in its good faith judgment that joint representation by counsel for the Indemnified Party and
the Indemnifying Party violates or would violate applicable ethical and professional rules, then the Indemnified Party (upon notice to the Indemnifying Party) may participate, together with counsel for the Indemnifying Party, in the defense,
compromise or settlement of such Third Party Claims, and the reasonable costs and expenses of such participation shall be payable by the Indemnifying Party. 
 (d) If the Indemnifying Party disputes in good faith the right of the Indemnified Party to indemnification under this Article VII
with respect to the Third Party Claim described in a Third Party Claim Notice, then in such event (i) the Indemnified Party may defend the Third Party Claim with counsel of its choice; provided, however, that the Indemnified Party
(x) shall diligently defend such Third Party Claim and (y) may not enter into a settlement thereof without obtaining approval of the Indemnifying Party (which approval shall not be unreasonable withheld, conditioned or delayed), unless the
Indemnified Party will not be seeking indemnification for any amounts paid pursuant to such settlement thereof or for any other consequences (except to the extent such settlement would not prejudice the rights of the Indemnifying Party); and
(ii) the amount of Damages incurred by the Indemnified Party in connection with such Third Party Claim shall be a disputed indemnification claim to be resolved by settlement between the Indemnifying Party and the Indemnified Party or by
proceedings commenced in an appropriate court of competent jurisdiction by either the Indemnifying Party or the Indemnified Party or by any other mutually agreeable method. 
 (e) A failure to give timely notice or to include any specified information in any notice as provided in Section 7.5(a) or
7.5(b) will not affect the rights or obligations of any Party hereunder, except and only to the extent that, as a result of such failure, any Party that was entitled to receive such notice or information was deprived of its right to recover
any payment under its applicable insurance coverage or was otherwise prejudiced as a result of such failure. 
 7.6 Exclusive Remedy and
Release. Except as set forth in Section 8.17, the indemnification and remedies set forth in this Article VII shall, from and after the Closing, constitute the sole and exclusive remedies of the Parties with respect to any
breach of representation or warranty or non-performance, partial or total, of any covenant or agreement contained in this Agreement. EXCEPT WITH RESPECT TO CLAIMS IDENTIFIED IN THE PREVIOUS SENTENCE, EFFECTIVE UPON THE CLOSING, BUYER HEREBY
WAIVES, RELEASES, ACQUITS AND FOREVER DISCHARGES SELLER AND ITS AFFILIATES, AND ITS AND THEIR RESPECTIVE OFFICERS, DIRECTORS, MANAGERS, MEMBERS, PARTNERS, STOCKHOLDERS, EMPLOYEES OR 

  

 54 

 
AGENTS, OR ANY OTHER PERSON ACTING ON BEHALF OF SELLER, OF AND FROM ANY AND ALL CLAIMS, ACTIONS, CAUSES OF ACTION, DEMANDS, RIGHTS, DAMAGES, COSTS,
EXPENSES, LOSSES OR COMPENSATION WHATSOEVER, WHETHER DIRECT OR INDIRECT, KNOWN OR UNKNOWN, FORESEEN OR UNFORESEEN, WHICH BUYER NOW HAS OR MAY HAVE OR WHICH MAY ARISE AFTER THE CLOSING DATE DIRECTLY OR INDIRECTLY, INCLUDING WITHOUT LIMITATION ANY OF
THE FOREGOING THAT IS FROM OR RELATING TO THE POSSESSION, USE, HANDLING, MANAGEMENT, DISPOSAL, INVESTIGATION, REMEDIATION, CLEANUP OR RELEASE OF ANY WASTES OR OTHER SUBSTANCES GOVERNED BY ENVIRONMENTAL LAWS OR ANY ENVIRONMENTAL LAW APPLICABLE
THERETO; PROVIDED, HOWEVER, THAT THE FOREGOING DOES NOT APPLY WITH RESPECT TO ANY ACTIONS TAKEN BY SELLER OR ITS AFFILIATES AFTER THE CLOSING DATE NOT OTHERWISE PROVIDED FOR UNDER ANY OF THE TRANSACTION DOCUMENTS. 
 ARTICLE VIII 
 MISCELLANEOUS 

 8.1 Termination of Agreement. Anything herein to the contrary notwithstanding, this Agreement and the transactions contemplated by
this Agreement may be terminated at any time before the Closing as follows: 
 (a) by the mutual consent of Buyer and Seller
as evidenced in writing signed by each of Buyer and Seller; 
 (b) by Buyer, if there has been a material breach by Seller of
any representation, warranty or covenant contained in this Agreement that would give rise to the failure of a condition to the obligations of Buyer at the Closing and, if such breach is of a character that it is capable of being cured, such breach
has not been cured by Seller within 30 days after written notice thereof from Buyer, provided that Buyer is not in material breach of any of its representations, warranties or covenants contained in this Agreement at such time; 
 (c) by Seller, if there has been a material breach by Buyer of any representation, warranty or covenant contained in this Agreement that
would give rise to the failure of a condition to the obligations of Seller at the Closing and, if such breach is of a character that it is capable of being cured, such breach has not been cured by Buyer within 30 days after written notice thereof
from Seller, provided that Seller is not in material breach of any of its representations, warranties or covenants contained in this Agreement at such time; 
 (d) by either Buyer or Seller if any Governmental Authority having competent jurisdiction has issued a final, non-appealable Order,
decree, ruling or injunction (other than a temporary restraining order) or taken any other action permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement; or 
  

 55 

 (e) by either Buyer or Seller, if the transactions contemplated hereby have not been
consummated within 180 days after the date of this Agreement; provided, however, that neither Buyer nor Seller will be entitled to terminate this Agreement pursuant to this Section 8.1(e) if such Person’s breach of this
Agreement has prevented the consummation of the transactions contemplated by this Agreement. 
 8.2 Effect of Termination. If this
Agreement is terminated as provided in Section 8.1, this Agreement shall forthwith become void and there shall be no Liability on the part of any Party hereto with respect thereto, but nothing herein shall relieve any Party from
Liability for any breach prior to such termination. 
 8.3 No Third Party Beneficiaries. Nothing in this Agreement shall provide any
benefit to any third party or entitle any third party to any claim, cause of action, remedy or right of any kind, it being the intent of the Parties that this Agreement shall not be construed as a third party beneficiary contract; provided,
however, that the indemnification provisions in Article VII shall inure to the benefit of Buyer Indemnified Parties and Seller Indemnified Parties as provided herein. 
 8.4 Expenses. Except as otherwise expressly provided herein, each Party hereto shall bear all of its legal, accounting and other costs and
expenses incident to the negotiation of this Agreement and the performance of the transactions contemplated hereby.

Headings. The descriptive headings of the several Articles and Sections of this Agreement are inserted for convenience only and do not constitute a part of the Agreement. 
 8.7 Entire Agreement. The Transaction Documents, the documents to be executed thereunder and the exhibits and Schedules attached thereto
constitute the entire agreement between the Parties hereto pertaining to the subject matter hereof and supersede all prior and contemporaneous agreements, understandings, negotiations and discussions, whether oral or written, of the Parties
pertaining to the subject matter hereof. 
 8.8 Waiver. Any Party hereto may (a) extend the time for the performance of any of
the obligations or other acts of any other Party hereto or (b) waive compliance with any of the agreements of any other Party or with any conditions to its own obligations. Any agreement on the part of a Party hereto to any such extension or
waiver shall be valid if set forth in an instrument in writing signed on behalf of such Party. 
 8.9 Amendment. This Agreement may
not be amended except by an instrument in writing signed by each of the Parties hereto. No supplement, alteration or modification of this Agreement shall be binding unless executed in writing by the Parties hereto. 
 8.10 Public Statements. No Party (or Affiliate thereof) shall issue a press release announcing the execution and delivery of this Agreement, or
the Closing of the transactions contemplated by this Agreement without the prior written consent of Buyer and Seller, which consent shall not be unreasonably withheld, except as required by applicable Law or the applicable rules or regulations of
any securities exchange or Governmental Authority, as reasonably determined by legal counsel for the Party issuing such press release. 
 8.11 Assignment. The provisions of this Agreement will be binding upon and inure to the benefit of the Parties to this Agreement and their respective successors and assigns, but no 

  

 57 

 
Party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the prior written consent of each other Party
to this Agreement. 
 8.12 Independent Covenants. The covenants contained herein are independent and separate, and in the event that
any provision contained herein is declared invalid or illegal, the other provisions hereof shall not be affected or impaired thereby and shall remain valid and enforceable. 
 8.13 Governing Law. This Agreement and the other documents delivered pursuant hereto and the legal relations between the Parties shall be governed
and construed in accordance with the Laws of the State of New York, without giving effect to principles of conflicts of law. 
 8.14
Jurisdiction; Venue. Except as otherwise expressly provided in this Agreement, any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions
contemplated hereby may be brought in any state or federal court of competent jurisdiction in New York, New York and each of the Parties hereby consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any
such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by Law, any objection which it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such
suit, action or proceeding which is brought in any such court has been brought in an inconvenient form. Process in any such suit, action or proceeding may be served on any Party anywhere in the world, whether within or without the jurisdiction of
any such court. Without limiting the foregoing, each Party agrees that service of process on such Party as provided in Section 8.5 will be deemed effective service of process on such Party. 
 8.15 Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed an original but
all of which together shall constitute one and the same instrument. A facsimile counterpart of this Agreement shall be sufficient to bind a Party hereto to the same extent as an original. 
 8.16 Limitation of Liability. NOTWITHSTANDING ANY PROVISION OF THIS AGREEMENT TO THE CONTRARY, IN NO EVENT SHALL ANY PARTY TO THIS AGREEMENT BE
LIABLE TO ANY OTHER PARTY OR ANY INDEMNIFIED PARTY FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL OR OTHER INDIRECT DAMAGES OR ANY PUNITIVE OR EXEMPLARY DAMAGES ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT (INCLUDING ANY BREACH OR ALLEGED BREACH
OF ANY REPRESENTATION, WARRANTY, COVENANT OR AGREEMENT IN THIS AGREEMENT), WHETHER SUCH DAMAGES ARE BASED ON BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE) OR OTHER THEORY OF LIABILITY, INCLUDING DIMINUTION OF VALUE OR DAMAGES DETERMINED AS A
MULTIPLE OF INCOME. 
 8.17 Specific Enforcement. The Parties acknowledge that, in view of the uniqueness of the Business and the
transactions contemplated hereby, Buyer and Seller will not have an adequate remedy at Law for money damages in the event that this Agreement has not been performed in accordance with its terms by the other Parties, and therefore, the Parties agree
that 

  

 58 

 
Buyer or Seller, as the case may be, shall be entitled to specific enforcement of the terms hereof with respect to the transactions contemplated hereby
(including without limitation to compel a Party to consummate the transactions contemplated by this Agreement in order to effect the Closing, subject to the terms and conditions of this Agreement) in the event of breach by the other Party in
addition to any other remedy to which the Parties may be entitled, at Law or in equity, for such breach. In addition, the Parties agree that any breach of any covenants or agreements set forth in this Agreement by Seller may cause Buyer irreparable
injury and damage. Seller, therefore, expressly agrees that Buyer shall be entitled to seek injunctive and/or other equitable relief to prevent an anticipatory or continuing breach and to secure enforcement of any part of such covenants or
agreements. Nothing herein shall be construed as a waiver by Buyer or Seller of any right they may now have or hereafter acquire to monetary damages from the other Parties by reason of any injury to its property, or otherwise arising out of any
breach or any otherwise wrongful act or omission by such Parties. 
 8.18 Further Assurances. The Parties shall execute and deliver
any and all other instruments or documents and take such other and further action as may be reasonably necessary or appropriate in order to give effect to the terms and provisions of this Agreement. 
 8.19 Parent Guaranty. 
 (a) Seller Parent hereby unconditionally and irrevocably guarantees all obligations of Seller now or hereafter existing under this Agreement and the Assignment, including Article VII, and any and all expenses (including
reasonable counsel fees and expenses) incurred by Buyer in enforcing any rights under this Agreement (collectively, the “Seller Obligations”). Buyer Parent hereby unconditionally and irrevocably guarantees all obligations of Buyer
now or hereafter existing under this Agreement, including Article VII, and any and all expenses (including reasonable counsel fees and expenses) incurred by Seller in enforcing any rights under this Agreement (collectively, the
“Buyer Obligations,” and together with the Seller Obligations, as applicable to each respective Party, the “Obligations”). For the purposes of this Section 8.19: (i) the term
“Guarantor” shall refer to either Seller Parent or Buyer Parent, as applicable; (ii) the term “Obligor” shall refer to either Seller or Buyer, as applicable; and (iii) the term
“Beneficiary” shall mean either Seller or Buyer, as applicable, that is the intended beneficiary of the relevant parent guaranty. 
 (b) Guarantor guarantees that the Obligations will be performed strictly in accordance with the terms of this Agreement, regardless of any Law, regulation or Order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of Obligor with respect thereto. The liability of Guarantor under this Section 8.19 shall be absolute and unconditional irrespective of (i) any lack of validity, enforceability or
genuineness of any provision of this Agreement or any other agreement or instrument relating thereto, (ii) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or
waiver of or any consent to departure from this Agreement, (iii) any release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Obligations; or (iv) any other circumstance which might otherwise
constitute a defense available to or a discharge of Obligor or Guarantor. 
  

 59 

 (c) The guaranty set forth in this Section 8.19 shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of any of the Obligations is rescinded or must otherwise be returned by Beneficiary upon the insolvency, bankruptcy or reorganization of Obligor or otherwise, all as though
such payment had not been made. Guarantor hereby waives promptness, diligence, notice of acceptance and any other notice with respect to any of the Obligations and this guaranty. Guarantor hereby irrevocably waives any claims or other rights that it
may now or hereafter acquire against Beneficiary that arise from the existence, payment, performance or enforcement of Guarantor’s respective obligations under this guaranty or this Agreement, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of Beneficiary against Obligor, whether or not such claim, remedy or right arises in equity or under contract, statute or
common law, including, without limitation, the right to take or receive from the Obligor, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right. If any
amount shall be paid to Guarantor in violation of the preceding sentence at any time prior to the later of the cash payment in full of the Obligations and all other amounts payable under this guaranty and the termination date, such amount shall be
held in trust for the benefit of Beneficiary, shall forthwith be paid to Buyer to be credited and applied to the Obligations and all other amounts payable under this guaranty, in accordance with the terms of this Agreement and this guaranty, or to
be held as collateral for any Obligations or other amounts payable under this guaranty thereafter arising. 
 (d) The guaranty
by Buyer Parent set forth in this Section 8.19 shall (i) remain in full force and effect until the first anniversary of the Closing Date or the termination of this Agreement, provided, however, that if Buyer Parent has been
notified in writing of any claims with regard to Buyer Obligations prior to the first anniversary of the Closing Date, it shall remain in full force and effect until discharge or payment in full of the Obligations, (ii) be binding upon Buyer
Parent and its respective successors and assigns, and (iii) inure to the benefit of and be enforceable by Beneficiary and its successors, transferees and assigns. 
 (e) The guaranty by Seller Parent set forth in this Section 8.19 shall (i) remain in full force and effect until the
third anniversary of the Closing Date, provided, however, that if Buyer Parent has been notified in writing of any claims with regard to Seller Obligations prior to the third anniversary of the Closing Date, it shall remain in full force and
effect until discharge or payment in full of such Seller Obligations and all other amounts payable under this guaranty (if any), (ii) be binding upon Seller Parent and its respective successors and assigns, and (iii) inure to the benefit
of and be enforceable by Beneficiary and its successors, transferees and assigns 
 (g) Each Guarantor hereby makes the same
representations set forth in Sections 3.1, 3.4, and 3.5, modified only to reflect that both Guarantors are limited partnerships and are organized under the laws of the State of Delaware. Except as provided in this
Section 8.19, the Guarantors are not making any representations, warranties or covenants under this Agreement. 
  

 60 

 (f) Beneficiary agrees that Guarantor shall have no obligation under this Agreement
except for the guaranty set forth in this Section 8.19.

Agreement, on the date specified for the issuance, renewal or extension of a Letter of Credit, the Administrative Agent shall issue, renew or extend such Letter of Credit to the beneficiary thereof. 
 In conjunction with the issuance of each Letter of Credit, the Borrower shall execute a Letter of Credit Agreement. In the event of any conflict between
any provision of a Letter of Credit Agreement and this Agreement, the Borrower, the Issuing Bank, the Administrative Agent and the Lenders hereby agree that the provisions of this Agreement shall govern. 
  

 17 

 The Issuing Bank will send to the Borrower and each Lender, immediately upon issuance of any Letter of
Credit, or an amendment thereto, a true and complete copy of such Letter of Credit, or such amendment thereto. 
 Section 2.03 Changes of
Commitments. 
 (a) The Borrower shall have the right to terminate or to reduce the amount of the Aggregate Maximum
Revolver Amounts at any time, or from time to time, upon not less than thirty (30) days’ prior notice to the Administrative Agent (who shall promptly notify the Lenders) of each such termination or reduction, which notice shall specify the
effective date thereof and the amount of any such reduction (which shall not be less than Three Million Dollars ($3,000,000) or any whole multiple of One Million Dollars ($1,000,000) in excess thereof, and no more than an amount by which the
Aggregate Maximum Revolver Amounts would be less than the aggregate outstanding principal amount of the Loans plus the LC Exposure) and shall be irrevocable and effective only upon receipt by the Administrative Agent. 
 (b) The Aggregate Maximum Revolver Amounts, once terminated or reduced, may not be reinstated. 
 Section 2.04 Fees. 
 (a) Commitment Fee. The Borrower shall pay to the Administrative Agent for the account of each Lender a commitment fee on the daily average unused amount of the aggregate Revolver Commitments, up to, but excluding, the
Termination Date in respect of the Revolver Facility at a rate per annum equal to 0.50%. Accrued commitment fees shall be payable quarterly in arrears on each Quarterly Date and on the Termination Date in respect of the Revolver Facility.

 (b) Letter of Credit Fees. 
 (i) The Borrower agrees to pay the Administrative Agent, for the account of each Lender, commissions for issuing the Letters of Credit on
the daily average outstanding of the maximum liability of the Issuing Bank existing from time to time under such Letter of Credit (calculated separately for each Letter of Credit) at the rate per annum equal to the Applicable Margin in effect from
time to time for LIBOR Loans, provided, that each Letter of Credit shall bear a minimum commission of Five Hundred Dollars ($500) and further provided, during any period commencing on the date of an Event of Default until the same is
paid in full or all Events of Default are cured and waived, equal to the Post-Default Rate. Each Letter of Credit shall be deemed to be outstanding up to the full face amount of the Letter of Credit until the Issuing Bank has received the canceled
Letter of Credit or a written cancellation of the Letter of Credit from the beneficiary of such Letter of Credit in form and substance acceptable to the Issuing Bank, or for any reductions in the amount of the Letter of Credit (other than from a
drawing), written notification from the beneficiary of such Letter of Credit. Such commissions are payable in advance at issuance of the Letter of Credit for the first year thereof and thereafter, quarterly in arrears on each Quarterly Date and upon

Fee Letter. The Borrower shall pay to Administrative Agent and the Sole Lead Arranger for their respective accounts such other fees as are set forth in the Fee Letter on the dates specified therein to the extent not paid prior to the
Closing Date. 
 Section 2.05 Several Obligations. The failure of any Lender to make any Loan to be made by it or to provide funds for
disbursements or reimbursements under Letters of Credit on the date specified therefor shall not relieve any other Lender of its obligation to make its Loan or provide funds on such date, but no Lender shall be responsible for the failure of any
other Lender to make a Loan to be made by such other Lender or to provide funds to be provided by such other Lender. 
 Section 2.06
Notes. The Loans made by each Lender shall be evidenced by a Revolver Note dated as of (i) the Closing Date or (ii) the effective date of an Assignment and Assumption, payable to the order of such Lender in a principal amount equal to
its Maximum Revolver Amount as originally in effect and otherwise duly completed and such substitute Notes as required by Section 12.06. The date, amount, Type, interest rate and Interest Period of each Loan made by each Lender,
and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note, and, prior to any transfer may be endorsed by such Lender on the schedule attached to such Note or any continuation thereof or on
any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer
by any Lender of its Note. 
 Section 2.07 Prepayments. 
 (a) Voluntary Prepayments. The Borrower may prepay the Base Rate Loans upon not less than one (1) Business Day’s
prior notice to the Administrative Agent (which shall promptly notify the Lenders), which notice shall specify the prepayment date (which shall be a Business Day) and the amount of the prepayment (which shall be at least One Hundred Thousand Dollars
($100,000) or the remaining aggregate principal balance outstanding on the Notes) and shall be irrevocable and effective only upon receipt by the Administrative Agent, provided that interest on the principal prepaid, accrued to the prepayment date,
shall be paid on the prepayment date. The Borrower may prepay LIBOR Loans on the same conditions as for Base Rate Loans (except that prior notice to the Administrative Agent shall be not less than three (3) Business Days for LIBOR Loans) and in
addition such prepayments of LIBOR Loans shall be subject to the terms of Section 5.05 and shall be in an amount equal to all of the LIBOR Loans for the Interest Period prepaid. In the event of a voluntary prepayment of any Loans
pursuant to this Section 2.07(a), Borrower shall be entitled to reborrow such amounts pursuant to Section 2.01(a). 
 (b) Generally. Prepayments permitted under this Section 2.07 shall be without premium or penalty, except as required under Section 5.05 for prepayment of LIBOR
Loans. With respect to the Loans, any voluntary prepayments may be reborrowed subject to the then effective Aggregate Maximum Revolver Amount. 
 Section 2.08 Assumption of Risks. The Borrower assumes all risks of the acts or omissions of any beneficiary of any Letter of Credit or any transferee thereof with respect to its use of such Letter of Credit. Neither the Issuing Bank
(except in the case of gross negligence or willful misconduct on the part of the Issuing Bank or any of its employees), its correspondents nor any Lender shall be responsible for the validity, sufficiency or genuineness of certificates or other
documents or any endorsements thereon, 
  

 19 

 
even if such certificates or other documents should in fact prove to be invalid, insufficient, fraudulent or forged; for errors, omissions, interruptions or
delays in transmissions or delivery of any messages by mail, telex, or otherwise, whether or not they be in code; for errors in translation or for errors in interpretation of technical terms; the validity or sufficiency of any instrument
transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; the failure of any
beneficiary or any transferee of any Letter of Credit to comply fully with conditions required in order to draw upon any Letter of Credit; or for any other consequences arising from causes beyond the Issuing Bank’s control or the control of the
Issuing Bank’s correspondents. In addition, neither the Issuing Bank, the Administrative Agent nor any Lender shall be responsible for any error, neglect, or default of any of the Issuing Bank’s correspondents; and none of the above shall
affect, impair or prevent the vesting of any of the Issuing Bank’s, the Administrative Agent’s or any Lender’s rights or powers hereunder or under the Letter of Credit Agreements, all of which rights shall be cumulative. The Issuing
Bank and its correspondents may accept certificates or other documents that appear on their face to be in order, without responsibility for further investigation of any matter contained therein regardless of any notice or information to the
contrary. In furtherance and not in limitation of the foregoing provisions, the Borrower agrees that any action, inaction or omission taken or not taken by the Issuing Bank or by any correspondent for the Issuing Bank in good faith in connection
with any Letter of Credit, or any related drafts, certificates, documents or instruments, shall be binding on the Borrower and shall not put the Issuing Bank or its correspondents under any resulting liability to the Borrower. 
 Section 2.09 Obligation to Reimburse and to Prepay. 
 (a) If a disbursement by the Issuing Bank is made under any Letter of Credit, the Borrower shall pay to the Administrative Agent within two (2) Business Days after notice of any such disbursement is received by
the Borrower, the amount of each such disbursement made by the Issuing Bank under the Letter of Credit (if such payment is not sooner effected as may be required under this Section 2.09 or under other provisions of the Letter of
Credit), together with interest on the amount disbursed from and including the date of disbursement until payment in full of such disbursed amount at a varying rate per annum equal to (i) the then applicable interest rate for Base Rate Loans
through the second Business Day after notice of such disbursement is received by the Borrower and (ii) thereafter, the Post-Default Rate for Base Rate Loans (but in no event to exceed the Highest Lawful Rate) for the period from and including
the third Business Day following the date of such disbursement to and including the date of repayment in full of such disbursed amount. The obligations of the Borrower under this Agreement with respect to each Letter of Credit shall be absolute,
unconditional and irrevocable and shall be paid or performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever, including, without limitation, but only to the fullest extent permitted by applicable law, the
following circumstances: (i) any lack of validity or enforceability of this Agreement, any Letter of Credit or any of the Security Instruments; (ii) any amendment or waiver of (including any default), or any consent to departure from this
Agreement (except to the extent permitted by any amendment or waiver), any Letter of Credit or any of the Security Instruments; (iii) the existence of any claim, set-off, defense or other rights which the Borrower may have at any time against
the beneficiary of any Letter of Credit or any transferee of any Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Bank, the Administrative Agent, any Lender or any other Person,
whether in connection with this Agreement, any Letter of Credit, the Security Instruments, the transactions contemplated hereby or any unrelated transaction; (iv) any statement, certificate, draft, notice or any other document presented under
any Letter of Credit proves to have been forged, fraudulent, insufficient or invalid in any respect or any statement therein proves to have been untrue or inaccurate in any 

  

 20 

 
respect whatsoever; (v) payment by the Issuing Bank under any Letter of Credit against presentation of a draft certificate which appears on its face to
comply, but does not comply, with the terms of such Letter of Credit; and (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing. 
 Notwithstanding anything in this Agreement to the contrary, the Borrower will not be liable for payment or performance that results from the gross
negligence or willful misconduct of the Issuing Bank, except (i) where the Borrower or any Subsidiary actually recovers the proceeds for itself or the Issuing Bank of any payment made by the Issuing Bank in connection with such gross negligence
or willful misconduct or (ii) in cases where the Administrative Agent makes payment to the named beneficiary of a Letter of Credit. 
 (b) In the event of the occurrence of any Event of Default or the maturity of the Revolver Notes, whether by acceleration or otherwise, an amount equal to the LC Exposure shall be deemed to be forthwith due and owing
by the Borrower to the Issuing Bank, the Administrative Agent and the Lenders as of the date of any such occurrence; and the Borrower’s obligation to pay such amount shall be absolute and unconditional, without regard to whether any beneficiary
of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of
set-off, counterclaim or recoupment which the Borrower may now or hereafter have against any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such payments shall be held by the
Issuing Bank on behalf of the Lenders as cash collateral securing the LC Exposure in an account or accounts at the Principal Office; and the Borrower hereby grants to and by its deposit with the Administrative Agent grants to the Administrative
Agent a security interest in such cash collateral. In the event of any such payment by the Borrower of amounts contingently owing under outstanding Letters of Credit and in the event that thereafter drafts or other demands for payment complying with
the terms of such Letters of Credit are not made prior to the respective expiration dates thereof, the Administrative Agent agrees, if no Event of Default has occurred and is continuing or if no other amounts are outstanding under this Agreement,
the Notes or the Security Instruments, to remit to the Borrower amounts for which the contingent obligations evidenced by the Letters of Credit have ceased. 
 (c) Each Lender severally and unconditionally agrees that it shall promptly reimburse the Issuing Bank an amount equal to such
Lender’s Percentage Share of any disbursement made by the Issuing Bank under any Letter of Credit that is not reimbursed according to this Section 2.09. 
 (d) Notwithstanding anything to the contrary contained herein, if no Event of Default has occurred and is continuing, and subject to
Availability under the Revolver Facility, to the extent the Borrower has not reimbursed the Issuing Bank for any drawn upon Letter of Credit within one (1) Business Day after notice of such disbursement has been received by the Borrower, the
amount of such Letter of Credit reimbursement obligation shall automatically be funded by the Lenders as a Loan hereunder and used by the Lenders to pay such Letter of Credit reimbursement obligation. If an Event of Default has occurred and is
continuing, or if the funding of such Letter of Credit reimbursement obligation as a Loan would cause the aggregate amount of all Loans outstanding to exceed the Aggregate Maximum Revolver Amount (after reduction for LC Exposure), such Letter of
Credit reimbursement obligation shall not be funded as a Loan, but instead shall accrue interest as provided in Section 2.09(a). 
  

 21 

 Section 2.10 Lending Offices. The Loans of each Type made by each Lender shall be made and
maintained at such Lender’s Applicable Lending Office for Loans of such Type.

each Lender, interest on the unpaid principal amount of each Loan made by such Lender for the period commencing on the date such Loan is made to, but excluding, the date such Loan shall be paid in full, at the following rates per annum: 

(i) if such a Loan is a Base Rate Loan, the Base Rate (as in effect from time to time) plus the Applicable Margin, but in no event to
exceed the Highest Lawful Rate; and 
 (ii) if such a Loan is a LIBOR Loan, for each Interest Period relating thereto, the
Adjusted LIBOR for such Loan plus the Applicable Margin (as in effect from time to time), but in no event to exceed the Highest Lawful Rate. 
 (b) Post-Default Rate. Notwithstanding the foregoing, the Borrower will pay to the Administrative Agent, for the account of each Lender, interest at the applicable Post-Default Rate on any Loan made by
such Lender, and (to the fullest extent permitted by law) on any other amount payable by the Borrower hereunder, under any Loan Document or under any Note held by such Lender to or for account of such Lender, for the period commencing on the date of
an Event of Default until the same is paid in full or all Events of Default are cured or waived. 
 (c) Due
Dates. Accrued interest on Base Rate Loans shall be payable on each Quarterly Date commencing on October 1, 2006, and accrued interest on each LIBOR Loan shall be payable on the last day of the Interest Period therefor and, if such
Interest Period is longer than three months, at three-month intervals following the first day of such Interest Period, except that interest payable at the Post-Default Rate shall be payable from time to time on demand and interest on any LIBOR Loan
that is converted into a Base Rate Loan (pursuant to Section 5.04) shall be payable on the date of conversion (but only to the extent so converted). Any accrued and unpaid interest on the Loans on the Termination Date in respect
of the Revolver Facility shall be paid on such date. 
 (d) Determination of Rates. Promptly after the
determination of any interest rate provided for herein or any change therein, the Administrative Agent shall notify the Lenders to which such interest is payable and the Borrower thereof. Each determination by the Administrative Agent of an interest

 ARTICLE IV 
 Payments; Pro Rata Treatment; Computations; Etc. 
 Section 4.01 Payments. Except to the extent
otherwise provided herein, all payments of principal, interest and other amounts to be made by the Borrower under this Agreement, the Notes, Letters of Credit, and the Letter of Credit Agreements shall be made in Dollars, in immediately available
funds, to the Administrative Agent at such account as the Administrative Agent shall specify by notice to the Borrower from time to time, not later than 12:00 p.m. Charlotte, North Carolina time on the date on which such payments shall become due
(each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). Such payments shall be made without (to the fullest extent permitted by applicable law) defense, set-off or counterclaim.
Each payment received by the Administrative Agent under this Agreement or any Note for account of a Lender shall be paid promptly to such Lender in immediately available funds. Except as otherwise provided in the definition of “Interest
Period”, if the due date of any payment under this Agreement or any Note would otherwise fall on a day which is not a Business Day such date shall be extended to the next succeeding Business Day and interest shall be payable for any
principal so extended for the period of such extension. At the time of each payment to the Administrative Agent of any principal of or interest on any borrowing, the Borrower shall notify the Administrative Agent of the Loans to which such payment
shall apply. In the absence of such notice the Administrative Agent may specify the Loans to which such payment shall apply, but to the extent possible such payment or prepayment will be applied first to the Loans comprised of Base Rate Loans.

 Section 4.02 Pro Rata Treatment. Except to the extent otherwise provided herein, each Lender agrees that: (i) each borrowing
from the Lenders under Section 2.01 and each continuation and conversion under Section 2.02 shall be made from the Lenders pro rata in accordance with their Percentage Share of the aggregate Revolver
Commitments, each payment of fees under Sections 2.04(a) and 2.04(b)(i), shall be made for account of the Lenders pro rata in accordance with their Percentage Share of the aggregate Revolver Commitments, and each
termination or reduction of the amount of the Aggregate Maximum Revolver Amount under Section 2.03(a) shall be applied to the Revolver Commitment of each Lender, pro rata according to the amounts of its respective Revolver
Commitment; (ii) each payment of principal of Loans by the Borrower shall be made for account of the Lenders pro rata in accordance with the respective unpaid principal amount of the Loans held by the Lenders; (iii) each payment of
interest on Loans by the Borrower shall be made for account of the Lenders pro rata in accordance with the amounts of interest due and payable to the respective Lenders; (iv) each reimbursement by the Borrower of disbursements under Letters of
Credit shall be made for account of the Issuing Bank or, if funded by the Lenders, pro rata for the account of the Lenders in accordance with the amounts of reimbursement obligations due and payable to each respective Lender. 
 Section 4.03 Computations. Interest on LIBOR Loans and fees shall be computed on the basis of a year of 360 days and actual days elapsed
(including the first day but excluding the last day) occurring in the period for which such interest is payable, unless such calculation would exceed the Highest Lawful Rate, in which case interest shall be calculated on the per annum basis of a
year of 365 or 366 days, as the case may be. Interest on Base Rate Loans shall be computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed (including the first day but excluding the last day) occurring in the
period for which such interest is payable. 
 Section 4.04 Non-receipt of Funds by the Administrative Agent. Unless the Administrative
Agent shall have been notified by a Lender or the Borrower prior to the date on which such notifying party is scheduled to make payment to the Administrative Agent (in the case of a Lender) of the proceeds of a Loan or a payment under a Letter of
Credit to be made by it hereunder or (in the case of the 
  

 23 

 
Borrower) a payment to the Administrative Agent for account of one or more of the Lenders hereunder (such payment being herein called the
“Required Payment”), which notice shall be effective upon receipt, that it does not intend to make the Required Payment to the Administrative Agent, the Administrative Agent may assume that the Required Payment has been made
and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient(s) on such date and, if such Lender or the Borrower (as the case may be) has not in fact made the Required Payment
to the Administrative Agent, the recipient(s) of such payment shall, on demand, repay to the Administrative Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount
was so made available by the Administrative Agent until, but excluding, the date the Administrative Agent recovers such amount at a rate per annum which, for any Lender as recipient, will be equal to the Federal Funds Rate, and for the Borrower as
recipient, will be equal to the Base Rate plus the Applicable Margin. 
 Section 4.05 Set-off, Sharing of Payments, Etc. 

(a) The Borrower agrees that, in addition to (and without limitation of) any right of set-off, bankers’ lien or counterclaim a
Lender may otherwise have, each Lender shall have the right and be entitled (after consultation with the Administrative Agent), at its option, to offset balances held by it or by any of its Affiliates for account of the Borrower or any Subsidiary at
any of its offices, in Dollars or in any other currency, against any principal of or interest on any of such Lender’s Loans, or any other amount payable to such Lender hereunder, which is not paid when due (regardless of whether such balances
are then due to the Borrower), in which case it shall promptly notify the Borrower and the Administrative Agent thereof, provided that such Lender’s failure to give such notice shall not affect the validity thereof. 
 (b) If any Lender shall obtain payment of any principal of or interest on any Loan made by it to the Borrower under this Agreement (or
reimbursement as to any Letter of Credit) through the exercise of any right of set-off, banker’s lien or counterclaim or similar right or otherwise, and, as a result of such payment, such Lender shall have received a greater percentage of the
principal or interest (or reimbursement) then due hereunder by the Borrower to such Lender than the percentage received by any other Lenders, it shall promptly (i) notify the Administrative Agent and each other Lender thereof and
(ii) purchase from such other Lenders participations in (or, if and to the extent specified by such Lender, direct interests in) the Loans (or participations in Letters of Credit) made by such other Lenders (or in interest due thereon, as the
case may be) in such amounts, and make such other adjustments from time to time as shall be equitable, to the end that all the Lenders shall share the benefit of such excess payment (net of any expenses which may be incurred by such Lender in
obtaining or preserving such excess payment) pro rata in accordance with the unpaid principal and/or interest on the Loans held by each of the Lenders (or reimbursements of Letters of Credit). To such end all the Lenders shall make appropriate
adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. The Borrower agrees that any Lender so purchasing a participation (or direct interest) in the Loans made by
other Lenders (or in interest due thereon, as the case may be) may exercise all rights of set-off, banker’s lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans (or
Letters of Credit) in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with
respect to any other indebtedness or obligation of the Borrower. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a set-off to which this Section 4.05 applies,
such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this Section 4.05 to share the benefits of any recovery on
such secured claim. 
  

 24 

 Section 4.06 Taxes. 
 (a) Payments Free and Clear. Any and all payments by the Borrower hereunder shall be made, in accordance with
Section 4.01, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each
Lender, the Issuing Bank and the Administrative Agent, taxes imposed on its income, and franchise or similar taxes imposed on it, by (i) any jurisdiction (or political subdivision thereof) of which the Administrative Agent, the Issuing Bank or
such Lender, as the case may be, is a citizen or resident or in which such Lender has an Applicable Lending Office, (ii) the jurisdiction (or any political subdivision thereof) in which the Administrative Agent, the Issuing Bank or such Lender
is organized, or (iii) any jurisdiction (or political subdivision thereof) in which such Lender, the Issuing Bank or the Administrative Agent is presently doing business which taxes are imposed solely as a result of doing business in such
jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in
respect of any sum payable hereunder to the Lenders, the Issuing Bank or the Administrative Agent (i) the sum payable shall be increased by the amount necessary so that after making all required deductions (including deductions applicable to
additional sums payable under this Section 4.06) such Lender, the Issuing Bank or the Administrative Agent (as the case may be) shall receive 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 taxing authority or other Governmental Authority in accordance with applicable law. 
 (b) Other Taxes. In addition, to the fullest extent permitted by applicable law, the Borrower agrees to pay any present or
future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, any
Assignment and Assumption or any Security Instrument (hereinafter referred to as “Other Taxes”). 
 (c) Indemnification. To the fullest extent permitted by applicable law, the Borrower will indemnify each Lender, the Issuing Bank and the Administrative Agent for the full amount of Taxes and Other Taxes (including, but not
limited to, any Taxes or Other Taxes imposed by any Governmental Authority on amounts payable under this Section 4.06) paid by such Lender, the Issuing Bank or the Administrative Agent (on their behalf or on behalf of any
Lender), as the case may be, and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted unless the payment of such Taxes was
not correctly or legally asserted and such Lender’s payment of such Taxes or Other Taxes was the result of its gross negligence or willful misconduct. Any payment pursuant to such indemnification shall be made within thirty (30) days after
the date any Lender, the Issuing Bank or the Administrative Agent, as the case may be, makes written demand therefor. If any Lender, Issuing Bank or the Administrative Agent receives a refund or credit in respect of any Taxes or Other Taxes for
which such Lender, Issuing Bank or the Administrative Agent has received payment from the Borrower, it shall promptly notify the Borrower of such refund or credit and shall, if no Default has occurred and is continuing, within thirty 

  

 25 

 
(30) days after receipt of a request by the Borrower (or promptly upon receipt, if the Borrower has requested application for such refund or credit
pursuant hereto), pay an amount equal to such refund or credit to the Borrower without interest (but with any interest so refunded or credited), provided, that the Borrower, upon the request of such Lender,
the Issuing Bank or the Administrative Agent, agrees to return such refund or credit (plus penalties, interest or other charges) to such Lender or the Administrative Agent in the event such Lender or the Administrative Agent is required to repay
such refund or credit. 
 (d) Lender Representations. 
 (i) Each Lender represents that it is either (1) a banking association or corporation organized under the laws of the United States
of America or any state thereof or (2) it is entitled to complete exemption from United States withholding tax imposed on or with respect to any payments, including fees, to be made to it pursuant to this Agreement (A) under an applicable
provision of a tax convention to which the United States of America is a party or (B) because it is acting through a branch, agency or office in the United States of America and any payment to be received by it hereunder is effectively
connected with a trade or business in the United States of America. Each Lender that is not a banking association or corporation organized under the laws of the United States of America or any state thereof agrees to provide to the Borrower and the
Administrative Agent on the Closing Date, or on the date of its delivery of the Assignment and Assumption pursuant to which it becomes a Lender, and at such other times as required by United States law or as the Borrower or the Administrative Agent
shall reasonably request, two accurate and complete original signed copies of either (1) Internal Revenue Service Form W-8ECI (or successor form) certifying that all payments to be made to it hereunder will be effectively connected to a United
States trade or business (the “Form W-8ECI Certification”) or (2) Internal Revenue Service Form W-8BEN (or successor form) certifying that it is entitled to the benefit of a provision of a tax convention to which the
United States of America is a party which completely exempts from United States withholding tax all payments to be made to it hereunder (the “Form W-8BEN Certification”). In addition, each Lender agrees that if it previously
filed a Form W-8ECI Certification, it will deliver to the Borrower and the Administrative Agent a new Form W-8ECI Certification prior to the first payment date occurring in each of its subsequent taxable years; and if it previously filed a Form
W-8BEN Certification, it will deliver to the Borrower and the Administrative Agent a new certification prior to the first payment date falling in the third year following the previous filing of such certification. Each Lender also agrees to deliver
to the Borrower and the Administrative Agent such other or supplemental forms as may at any time be required as a result of changes in applicable law or regulation in order to confirm or maintain in effect its entitlement to exemption from United
States withholding tax on any payments hereunder, provided that the circumstances of such Lender at the relevant time and applicable laws permit it to do so. If a Lender determines, as a result of any change in either (i) a Governmental
Requirement or (ii) its circumstances, that it is unable to submit any form or certificate that it is obligated to submit pursuant to this Section 4.06, or that it is required to withdraw or cancel any such form or
certificate previously submitted, it shall promptly notify the Borrower and the Administrative Agent of such fact. If a Lender is organized under the laws of a jurisdiction outside the United States of America, unless the Borrower and the
Administrative Agent have received a Form W-8BEN Certification or Form W-8ECI Certification satisfactory to them indicating that all payments to be 

  

 26 

 
made to such Lender hereunder are not subject to United States withholding tax, the Borrower shall withhold taxes from such payments at the applicable
statutory rate. Each Lender agrees to indemnify and hold harmless the Borrower or Administrative Agent, as applicable, from any United States taxes, penalties, interest and other expenses, costs and losses incurred or payable by (i) the
Administrative Agent as a result of such Lender’s failure to submit any form or certificate that it is required to provide pursuant to this Section 4.06 or (ii) the Borrower or the Administrative Agent as a result of
their reliance on any such form or certificate which such Lender has provided to them pursuant to this Section 4.06. 
 (ii) For any period with respect to which a Lender has failed to provide the Borrower with the form required pursuant to this Section 4.06, if any (other than if such failure is due to a change in a
Governmental Requirement occurring subsequent to the date on which a form originally was required to be provided), such Lender shall not be entitled to indemnification under this Section 4.06 with respect to taxes imposed by the
United States which taxes would not have been imposed but for such failure to provide such forms; provided, however, that if a Lender, which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to taxes because
of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Lender shall reasonably request to assist such Lender to recover such taxes. 
 (iii) Any Lender claiming any additional amounts payable pursuant to this Section 4.06 shall use reasonable efforts
(consistent with legal and regulatory restrictions) to file any certificate or document requested by the Borrower or the Administrative Agent or to change the jurisdiction of its Applicable Lending Office or to contest any tax imposed if the making
of such a filing or change or contesting such tax would avoid the need for or reduce the amount of any such additional amounts that may thereafter accrue and would not, in the sole determination of such Lender, be otherwise disadvantageous to such
Lender. 
 ARTICLE V 
 Capital Adequacy 
 Section 5.01 Additional Costs. 
 (a) LIBOR Regulations, etc. The Borrower shall pay directly to each Lender from time to time such amounts as such Lender may
determine to be necessary to compensate such Lender for any costs which it determines are attributable to its making or maintaining of any LIBOR Loans or issuing or participating in Letters of Credit hereunder or its obligation to make any LIBOR
Loans or issue or participate in any Letters of Credit hereunder, or any reduction in any amount receivable by such Lender hereunder in respect of any of such LIBOR Loans, Letters of Credit (such increases in costs and reductions in amounts
receivable being herein called “Additional Costs”), resulting from any Regulatory Change which: (i) changes the basis of taxation of any amounts payable to such Lender under this Agreement or any Note in respect of any
of such LIBOR Loans or Letters of Credit (other than taxes imposed on the overall net income of such Lender or of its Applicable Lending Office for any of such LIBOR Loans by the jurisdiction in which such Lender has its principal office or
Applicable Lending Office); or (ii) imposes or modifies any reserve, special deposit, minimum capital, capital ratio or similar requirements relating to any extensions of credit or other assets of, or any deposits with or other liabilities of
such Lender, or the Commitment or Loans of such Lender or the London interbank 

  

 27 

 
market; or (iii) imposes any other condition affecting this Agreement or any Note (or any of such extensions of credit or liabilities) or such
Lender’s Commitment or Loans. Each Lender will notify the Administrative Agent and the Borrower of any event occurring after the Closing Date which will entitle such Lender to compensation pursuant to this Section 5.01(a) as
promptly as practicable after it obtains knowledge thereof and determines to request such compensation, and will designate a different Applicable Lending Office for the Loans of such Lender affected by such event if such designation will avoid the
need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender, provided that such Lender shall have no obligation to so designate an Applicable Lending Office located in the
United States. If any Lender requests compensation from the Borrower under this Section 5.01(a), the Borrower may, by notice to such Lender, suspend the obligation of such Lender to make additional Loans of the Type with respect
to which such compensation is requested until the Regulatory Change giving rise to such request ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable). 
 (b) Regulatory Change. Without limiting the effect of the provisions of Section 5.01(a), in the event
that at any time (by reason of any Regulatory Change or any other circumstances arising after the Closing Date affecting (i) any Lender, (ii) the London interbank market or (iii) such Lender’s position in such market), the
Adjusted LIBOR, as determined in good faith by such Lender, will not adequately and fairly reflect the cost to such Lender of funding its LIBOR Loans, then, if such Lender so elects, by notice to the Borrower and the Administrative Agent, the
obligation of such Lender to make additional LIBOR Loans shall be suspended until such Regulatory Change or other circumstances ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable). 

(c) Capital Adequacy. Without limiting the effect of the foregoing provisions of this Section 5.01
(but without duplication), the Borrower shall pay directly to any Lender from time to time on request such amounts as such Lender may reasonably determine to be necessary to compensate such Lender or its parent or holding company for any costs which
it determines are attributable to the maintenance by such Lender or its parent or holding company (or any Applicable Lending Office), pursuant to any Governmental Requirement following any Regulatory Change, of capital in respect of its Commitment,
its Note, or its Loans or any interest held by it in any Letter of Credit, such compensation to include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of such Lender or its parent or holding company
(or any Applicable Lending Office) to a level below that which such Lender or its parent or holding company (or any Applicable Lending Office) could have achieved but for such Governmental Requirement. Such Lender will notify the Borrower that it is
entitled to compensation pursuant to this Section 5.01(c) as promptly as practicable after it determines to request such compensation. 
 (d) Compensation Procedure. Any Lender notifying the Borrower of the incurrence of Additional Costs under this Section 5.01 shall in such notice to the Borrower and the Administrative
Agent set forth in reasonable detail the basis and amount of its request for compensation. Determinations and allocations by each Lender for purposes of this Section 5.01 of the effect of any Regulatory Change pursuant to
Section 5.01(a) or (b), or of the effect of capital maintained pursuant to Section 5.01(c), on its costs or rate of return of maintaining Loans or its obligation to make Loans or issue Letters of
Credit, or on amounts receivable by it in respect of Loans or Letters of Credit, and of the amounts required to compensate such Lender under this Section 5.01, shall be conclusive and binding for all purposes, provided that such
determinations and allocations are made on a reasonable basis. Any request for additional compensation under this Section 5.01 shall be paid by the Borrower within thirty (30) days of the receipt by the Borrower of the notice
described in this Section 5.01(d). 
  

 28 

 Section 5.02 Limitation on LIBOR Loans. Anything herein to the contrary notwithstanding, if, on or
prior to the determination of any Adjusted LIBOR for any Interest Period: 
 (a) the Administrative Agent determines (which
determination shall be conclusive, absent manifest error) that quotations of interest rates for the relevant deposits referred to in the definition of “Adjusted LIBOR” in Section 1.02 are not being provided in the
relevant amounts or for the relevant maturities for purposes of determining rates of interest for LIBOR Loans as provided herein; or 
 (b) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that the relevant rates of interest referred to in the definition of “Adjusted LIBOR” in
Section 1.02 upon the basis of which the rate of interest for LIBOR Loans for such Interest Period is to be determined are not sufficient to adequately cover the cost to the Lenders of making or maintaining LIBOR Loans; then the
Administrative Agent shall give the Borrower prompt notice thereof, and so long as such condition remains in effect, the Lenders shall be under no obligation to make additional LIBOR Loans. 
 Section 5.03 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to honor its obligation to make or maintain LIBOR Loans hereunder, then such Lender shall promptly notify the Borrower thereof and such Lender’s obligation to make LIBOR Loans shall be suspended until such time as such
Lender may again make and maintain LIBOR Loans (in which case the provisions of Section 5.04 shall be applicable). 
 Section 5.04 Base Rate Loans Pursuant to Sections 5.01, 5.02 and 5.03. If the obligation of any Lender to make LIBOR Loans shall be suspended pursuant to Sections 5.01, 5.02 or 5.03 (“Affected
Loans”), all Affected Loans which would otherwise be made by such Lender shall be made instead as Base Rate Loans (and, if an event referred to in Section 5.01(b) or Section 5.03 has occurred and
such Lender so requests by notice to the Borrower, all Affected Loans of such Lender then outstanding shall be automatically converted into Base Rate Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans
are so made as (or converted into) Base Rate Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its Base Rate Loans. 
 Section 5.05 Compensation. The Borrower shall pay to each Lender within thirty (30) days of receipt of written request of such Lender (which
request shall set forth, in reasonable detail, the basis for requesting such amounts and which shall be conclusive and binding for all purposes provided that such determinations are made on a reasonable basis), such amount or amounts as shall
compensate it for any loss, cost, expense or liability which such Lender determines are attributable to: 
 (a) any payment,
prepayment or conversion of a LIBOR Loan properly made by such Lender or the Borrower for any reason (including, without limitation, the acceleration of the Loans pursuant to Section 10.02) on a date other than the last day of the
Interest Period for such Loan; or 
 (b) any failure by the Borrower for any reason (including but not limited to, the failure
of any of the conditions precedent specified in Article VI to be satisfied) to borrow, continue or convert a LIBOR Loan from such Lender on the date for such borrowing, continuation or conversion specified in the relevant notice given
pursuant to Section 2.02(c). 
  

 29 

 Without limiting the effect of the preceding sentence, such compensation shall include an amount equal to the excess, if
any, of (i) the amount of interest which would have accrued on the principal amount so paid, prepaid or converted or not borrowed for the period from the date of such payment, prepayment or conversion or failure to borrow to the last day of the
Interest Period for such Loan (or, in the case of a failure to borrow, the Interest Period for such Loan which would have commenced on the date specified for such borrowing) at the applicable rate of interest for such Loan provided for herein over
(ii) the interest component of the amount such Lender would have bid in the London interbank market for Dollar deposits of leading banks in amounts comparable to such principal amount and with maturities comparable to such period (as reasonably
determined by such Lender). 
 ARTICLE VI

the Borrower upon the occasion of each borrowing hereunder and to issue, renew, extend or reissue Letters of Credit (including the Initial Funding), in each case if for the purposes of acquiring or carrying limited partnership units of Atlas

imposed hereby solely for the benefit of the Lenders, and no other Person may require satisfaction of any such condition precedent or be entitled to assume that the Lenders will refuse to make any Loan in the absence of strict compliance with such
conditions precedent. 
 Section 6.05 No Waiver. No waiver of any condition precedent shall preclude the Administrative Agent or the
Lenders from requiring such condition to be met prior to making any subsequent Loan or preclude the Lenders from thereafter declaring that the failure of the Borrower to satisfy such condition precedent constitutes a Default. 
 ARTICLE VII 
 Representations and
Warranties 
 Each of the Obligors represents and warrants to the Administrative Agent and the Lenders that (each representation and
warranty herein is given as of the Closing Date and shall be deemed repeated and reaffirmed on the dates of each borrowing and issuance, renewal, extension or reissuance of a Letter of Credit as provided in Section 6.02):

 Section 7.01 Corporate Existence. Each of the Obligors: (i) is a limited liability company or limited partnership duly
organized, formed, legally existing and in good standing under the laws of the jurisdiction of its incorporation or formation, as applicable; (ii) has all requisite organizational power, and has all material governmental licenses,
authorizations, consents and approvals necessary to own its assets and carry on its business as now being or as proposed to be conducted; and (iii) is qualified to do business in all jurisdictions in which the nature of the business conducted
by it makes such qualification necessary and where failure so to qualify would have a Material Adverse Effect. 
 Section 7.02 Financial

its consolidated subsidiaries for the fiscal year ended on said date, in each case including, on a consolidated basis, Atlas Pipeline Partners and its consolidated subsidiaries, heretofore furnished to each of the Lenders, are complete and correct
and fairly present the consolidated financial condition of APL General Partner and its consolidated subsidiaries including, on a consolidated basis, Atlas Pipeline Partners and its consolidated subsidiaries, as at said date and the results of its

or anticipated losses from any unfavorable commitments. Since the date of the Financial Statements, neither the business nor the Properties of APL General Partner, or any Subsidiary, including Atlas Pipeline Partners and its consolidated

 32 

 Section 7.03 Litigation. Except as disclosed to the Lenders in Schedule 7.03 hereto,
there is no litigation, legal, administrative or arbitral proceeding, investigation or other action of any nature pending or, to the knowledge of the Obligors, threatened against or affecting the Obligors or any Subsidiary which involves the
possibility of any judgment or liability against any Obligor or any Subsidiary not fully covered by insurance (except for normal deductibles), and which would have a Material Adverse Effect. 
 Section 7.04 No Breach. Neither the execution and delivery of the Loan Documents, nor compliance with the terms and provisions hereof, will
conflict with or result in a breach of, or require any consent which has not been obtained as of the Closing Date under, the respective charter, limited partnership agreement, articles of organization or by-laws of the Obligors or any Subsidiary, or
any Governmental Requirement, or any agreement or instrument to which any Obligor or any Subsidiary is a party or by which it is bound or to which it or its Properties are subject, or constitute a default under any such agreement or instrument, or
result in the creation or imposition of any Lien upon any of the revenues or assets of the Obligor or any Subsidiary pursuant to the terms of any such agreement or instrument, other than the Liens created by the Loan Documents. 
 Section 7.05 Authority. Each Obligor and each Subsidiary thereof has all necessary organizational power and authority to execute, deliver and
perform its obligations under the Loan Documents to which it is a party; and the execution, delivery and performance by each Obligor of the Loan Documents to which it is a party have been duly authorized by all necessary organizational action on its
part; and the Loan Documents constitute the legal, valid and binding obligations of each Obligor, enforceable in accordance with their terms. 
 Section 7.06 Approvals. No authorizations, approvals or consents of, and no filings or registrations with, any Governmental Authority or any other Person are necessary for the execution, delivery or performance by any Obligor of the
Loan Documents to which it is a party or for the validity or enforceability thereof, except for the recording and filing of the Security Instruments as required by this Agreement.

fees and expenses related to the Facility, and (iii) for Letters of Credit to support the obligations of the Obligors. Neither the Borrower nor any other Obligor is engaged principally, or as one of its important activities, in the business of
extending credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin stock (within the meaning of Margin Regulations) and no part of the proceeds of any Loan hereunder will be used to buy or carry any margin
stock, except limited partnership units of Atlas Pipeline Partners in compliance with the Margin Regulations and Section 6.03.

 (a) Each Obligor, each Subsidiary and each ERISA Affiliate have complied in all
material respects with ERISA and, where applicable, the Code regarding each Plan. 
 (b) Each Plan is, and has been,
maintained in substantial compliance with ERISA and, where applicable, the Code. 
 (c) No act, omission or transaction has
occurred which could result in imposition on any Obligor, any Subsidiary or any ERISA Affiliate (whether directly or indirectly) of (i) either a civil penalty assessed pursuant to section 502(c), (i) or (1) of ERISA or a tax imposed
pursuant to Chapter 43 of Subtitle D of the Code or (ii) breach of fiduciary duty liability damages under section 409 of ERISA. 
  

 33 

 (d) No contingent obligations remain due to the termination of any Plan (other than a
defined contribution plan) or any trust created under any such Plan since September 2, 1974. The only Plan that has been terminated was for The Atlas Group, Inc. No liability to the PBGC (other than for the payment of current premiums which are
not past due) by any Obligor, any Subsidiary or any ERISA Affiliate has been or is expected by any Obligor, any Subsidiary or any ERISA Affiliate to be incurred with respect to any Plan. No ERISA Event with respect to any Plan has occurred.

 (e) Full payment when due has been made of all amounts which any Obligor, any Subsidiary or any ERISA Affiliate is required
under the terms of each Plan or applicable law to have paid as contributions to such Plan, and no accumulated funding deficiency (as defined in section 302 of ERISA and section 412 of the Code), whether or not waived, exists with respect
to any Plan. 
 (f) The actuarial present value of the benefit liabilities under each Plan which is subject to Title IV
of ERISA does not, as of the end of each Obligor’s most recently ended fiscal year, exceed the current value of the assets (computed on a plan termination basis in accordance with Title IV of ERISA) of such Plan allocable to such benefit
liabilities. The term “actuarial present value of the benefit liabilities” shall have the meaning specified in section 4041 of ERISA. 
 (g) None of the Obligors, any Subsidiary or any ERISA Affiliate sponsors, maintains, or contributes to an employee welfare benefit plan, as defined in section 3(l) of ERISA, including, without limitation, any such
plan maintained to provide benefits to former employees of such entities, that may not be terminated by an Obligor, a Subsidiary or any ERISA Affiliate in its sole discretion at any time without any material liability. 
 (h) None of the Obligors, any Subsidiary or any ERISA Affiliate sponsors, maintains or contributes to, or has at any time in the preceding
six calendar years, sponsored, maintained or contributed to, any Multiemployer Plan. 
 (i) None of the Obligors, any
Subsidiary or any ERISA Affiliate is required to provide security under section 401 (a)(29) of the Code due to a Plan amendment that results in an increase in current liability for the Plan. 
 Section 7.09 Taxes. Except as set forth on Schedule 7.09, each Obligor and its Subsidiaries have filed all United States federal
income tax returns and all other tax returns which are required to be filed by them, or otherwise obtained appropriate extensions to file, and have paid all material taxes due pursuant to such returns or pursuant to any assessment received by any
Obligor or any Subsidiary, except such taxes that are being contested in good faith by appropriate proceedings and for which such Obligor or Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with GAAP. The
charges, accruals and reserves on the books of each Obligor and its Subsidiaries in respect of taxes and other governmental charges are, in the opinion of the Borrower, adequate. No tax lien has been filed and, to the knowledge of the Obligors, no
claim is being asserted with respect to any such tax, fee or other charge.

possession or abandonment claims and Liens, except Excepted Liens. 
 (b) All leases, rights of way, permits, licenses and
agreements necessary for the conduct of the business of each Obligor are valid and subsisting, in full force and effect and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give
rise to a default under any such lease rights of way, permits, licenses, which would affect in any material respect the conduct of the business of any Obligor. 
 (c) The rights, Properties and other assets presently owned, leased or licensed by each Obligor, including, without limitation, all
easements and rights of way, include all rights, Properties and other assets necessary to permit each Obligor to conduct its business in all material respects in the same manner as its business has been conducted prior to the Closing Date.

 (d) All of the assets and Properties of each Obligor which are reasonably necessary for the operation of its business are
in good working condition and are maintained in accordance with prudent business standards. 
 Section 7.11 No Material Misstatements.
To the Borrower’s knowledge, (i) no written information, statement, exhibit, certificate, document or report (not including financial projections referred to in clause (ii)) furnished to the Administrative Agent and the Lenders (or any of
them) by any Obligor in connection with the negotiation of this Agreement contains any material misstatement of fact or omitted to state a material fact or any fact necessary to make the statement contained therein not materially misleading in the
light of the circumstances in which made and (ii) all financial projections concerning the Borrower and its Subsidiaries furnished to the Administrative Agent and the Lenders (or any of them) have been prepared in good faith based upon
reasonable assumptions. There is no fact peculiar to any Obligor which has a Material Adverse Effect or in the future is reasonably likely to have a Material Adverse Effect and which has not been set forth in this Agreement or the other documents,
certificates and statements furnished to the Administrative Agent by or on behalf of the Obligors prior to, or on, the Closing Date in connection with the transactions contemplated hereby.

partnership interest of any other Person, other than Borrower’s ownership of the Subsidiaries described on Schedule 7.13. The Borrower and each Subsidiary of the Borrower has good and marketable title to all securities of the
Subsidiaries issued to it, free and clear of all liens and encumbrances, and all such securities have been duly and validly issued and are fully paid and nonassessable. The authorized securities and ownership of the Subsidiaries of the Borrower is
as shown on Schedule 7.13 attached hereto and made a part hereof. There are no Subsidiaries of the Borrower other than as disclosed on Schedule 7.13. 
  

 35 

 Section 7.14 Location of Business and Offices. Each Obligor’s principal place of business and
chief executive offices are located at the address stated on the signature page of this Agreement. 
 Section 7.15 Defaults under Material
Agreements. None of the Obligors is in default nor has any event or circumstance occurred which, but for the expiration of any applicable grace period or the giving of notice, or both, would constitute a default under any Material
Agreement to which any Obligor or any Subsidiary is a party or by which any Obligor or any Subsidiary is bound. No Default hereunder has occurred and is continuing. 
 Section 7.16 Environmental Matters. Except as would not have a Material Adverse Effect (or with respect to clauses (c), (d) and (e) below, where the

Subsidiaries nor the operations conducted thereon violate any order or requirement of any court or Governmental Authority or any Environmental Laws;

under Environmental Laws;

 Section 7.17 Compliance with Laws. None of the Obligors nor their Subsidiaries has violated any
Governmental Requirement or failed to obtain any license, permit, franchise or other governmental authorization necessary for the ownership of any of its Properties or the conduct of its business, which violation or failure would have (in the event
such violation or failure were asserted by any Person through appropriate action) a Material Adverse Effect. Except for such acts or failures to act as would not have a Material Adverse Effect, the Properties of the Obligors (and properties unitized
therewith) have been maintained, operated and developed in a good and workmanlike manner and in conformity with all applicable laws and all rules, regulations and orders of all duly constituted authorities having jurisdiction and in conformity with

 Section 7.18
Insurance. Schedule 7.18 attached hereto contains an accurate and complete description of all material policies of fire, liability, workers’ compensation and other forms of insurance owned or held by the Obligors. All
such policies are in full force and effect, all premiums with respect thereto covering all periods up to and including the date of the closing have been paid, and no notice of cancellation or termination has been received with respect to any such
policy. Such policies are sufficient for compliance with all requirements of law and of all agreements to which any Obligor is a party; are valid, outstanding and enforceable policies; provide adequate insurance coverage in at least such amounts and
against at least such risks (but including in any event public liability) as are usually insured against in the same general area by companies engaged in the same or a similar business for the assets and operations of the Obligors; will remain in
full force and effect through the respective dates set forth in Schedule 7.18 without the payment of additional premiums; and will not in any way be affected by, or terminate or lapse by reason of, the transactions contemplated by
this Agreement. Schedule 7.18 identifies all material risks, if any, which each Obligor and their respective general partner or sole member have designated as being self-insured. None of the Obligors has been refused any insurance
with respect to its assets or operations, nor has its coverage been limited below usual and customary policy limits, by an insurance carrier to which it has applied for any such insurance or with which it has carried insurance during the last three
years. 
 Section 7.19 Hedging Agreements. Schedule 7.19 sets forth, as of the Closing Date, a true and complete

thereof (including the type, term, effective date, termination date and notional amounts or volumes), the net mark to market value thereof, all credit support agreements relating thereto (including any margin required or supplied), and the counter
party to each such agreement. 
 Section 7.20 Restriction on Liens. None of the Obligors is a party to any agreement or arrangement
(other than this Agreement and the Security Instruments), or subject to any order, judgment, writ or decree, which either restricts or purports to restrict its ability to grant Liens to other Persons on or in respect of their respective assets or
Properties. 
 Section 7.21 Material Agreements. Set forth on Schedule 7.21 is
a complete list of all agreements, indentures, purchase agreements, obligations in respect of letters of credit, guarantees, partnership agreements, limited liability company agreements, other organizational documents, joint venture agreements, and
other instruments that (i) are material to the Obligors’ business, activities, and operation or ownership of such Obligors’ Property in effect or to be in effect as of the Closing Date (other than the Hedging Agreements set forth on
Schedule 7.19) or (ii) provide for, evidence, secure or otherwise relate to any Debt of any such Obligor and all obligations of any Obligor to issuers of surety or appeal bonds issued for account of any such Obligor (the
agreements referenced in clauses (i) and (ii) hereto, collectively, the “Material Agreements”). Upon request by Administrative Agent, the Borrower shall deliver, or caused to be
delivered, to the Administrative Agent and the Lenders a complete and correct copy of all such Material Agreements. 
  

 37

Obligor is directly and indirectly dependent upon each other Obligor for and in connection with their business activities and their financial resources; and each Obligor has determined, reasonably and in good faith, that such Obligor will receive
substantial direct and indirect economic and financial benefits from the extensions of credit made under this Agreement, and such extensions of credit are in the best interests of such Obligor, having regard to all relevant facts and circumstances.

security for the Indebtedness and to apply it on the principal and interest or other amounts owing on any of the Indebtedness, whether or not then due, in such order or manner as Administrative Agent may elect.

legend giving notice of such subordination. Any such Intercompany Notes or advances of any other Obligor due to such Obligor, if the Administrative Agent so requests, shall be collected, enforced and received by such Obligor as trustee for the
Lenders and be paid over to the Administrative Agent for the account of the Lenders on account of the Indebtedness but without affecting in any manner the liability of such Obligor under the other provisions of this Agreement or any other Loan
Document. Any Lien, claim, right or other encumbrance on any property of any Obligor in favor of any other Obligor is hereby subordinated in all respects to the Liens granted to the Administrative Agent for the benefit of the Lenders.

things necessary to ensure that the separate legal identity of the Borrower and General Partner will at all times be respected and that neither the Borrower, General Partner nor any of Borrower’s Subsidiaries will be liable for any obligations,
contractual or otherwise, of Atlas or any of the Atlas Direct Subsidiaries or other entity in which Atlas or any Atlas Direct Subsidiaries owns any equity interest (other than the Borrower, General Partner and Borrower’s Subsidiaries). Without
limiting the foregoing, the Borrower will (i) observe, and cause the General Partner to observe, all requirements, procedures and formalities necessary or advisable in order that the Borrower will for all purposes be considered a validly
existing entity separate and distinct from the General Partner, (ii) not permit any commingling of the assets of the General Partner, Atlas, or the Atlas Direct Subsidiaries with assets of the Borrower or any of its Subsidiaries which would
prevent such assets of such persons from being readily distinguished from the assets of the Borrower and its Subsidiaries and (iii) take reasonable and customary actions to ensure that creditors of the General Partner, Atlas or the Atlas Direct

a Responsible Officer specifying the nature thereof, what action the Obligors, the Subsidiary or the ERISA 
  

 43 

 
Affiliate is taking or proposes to take with respect thereto, and, when known, any action taken or proposed by the Internal Revenue Service, the Department
of Labor or the PBGC with respect thereto, and (iii) immediately upon receipt thereof, copies of any notice of the PBGCs intention to terminate or to have a trustee appointed to administer any Plan. With respect to each Plan (other than a
Multiemployer Plan), the Obligors will, and will cause each Subsidiary and ERISA Affiliate to, (i) satisfy in full and in a timely manner, without incurring any late payment or underpayment charge or penalty and without giving rise to any lien,
all of the contribution and funding requirements of section 412 of the Code (determined without regard to subsections (d), (e), (f) and (k) thereof) and of section 302 of ERISA (determined without regard to sections 303, 304 and 306
of ERISA), and (ii) pay, or cause to be paid, to the PBGC in a timely manner, without incurring any late payment or underpayment charge or penalty, all premiums required pursuant to sections 4006 and 4007 of ERISA.

guaranty any Indebtedness of any of the Unrestricted Entities; 
 (b) will not permit any Unrestricted Entity to hold any
equity or other ownership interest in any Obligor; and

make it apparent to all creditors of such Unrestricted Entity that such Unrestricted Entity is a legal entity separate and distinct from all of the Obligors and as such is solely responsible for its own debts. 
 Section 8.13 Material Agreements. The Obligors will enforce the obligations of Affiliates that are parties to the Material Agreements to the same
extent as they would enforce similar obligations of unrelated third parties. 
 Section 8.14 Guaranties. As an inducement to the
Administrative Agent and the Lenders to enter into this Agreement, each Obligor (other than the Borrower) shall execute and deliver to Administrative Agent a Guaranty Agreement substantially in the form and upon the terms of Exhibit G,
providing for the guaranty of payment and performance of the Indebtedness. In addition, at the time of the formation or acquisition of any Subsidiary (other than the Unrestricted Entities), the Borrower shall cause such Subsidiary to execute and
deliver to the Administrative Agent (i) a Guaranty Agreement substantially in the form and upon the terms of Exhibit G, providing for the guaranty of payment and performance of the Indebtedness, (ii) Security Instruments in
form and substance satisfactory to the Administrative Agent creating liens and security interests in all assets and properties of such Subsidiary and in the equity interest in such Subsidiary except for any equity interests in Unrestricted Entities,
and (iii) such other documents and instruments as may be required with respect to such Subsidiary pursuant to Section 8.05. At the time of the formation or acquisition of any Subsidiary or any Unrestricted Entity, Borrower

Affiliates. None of the Obligors will enter into any transaction, including, without limitation, any purchase, sale, lease or exchange of Property or the rendering of any service, with any Affiliate unless such transactions are otherwise
permitted under this Agreement, are in the ordinary course of its business and are upon fair and reasonable terms no less favorable to it than it would obtain in a comparable arm’s length transaction with a Person not an Affiliate; provided,

cash collateral to secure the LC Exposure as provided in Section 2.09(b)) to be forthwith due and payable, whereupon such amounts shall be immediately due and payable without presentment, demand, protest, notice of intent to
accelerate, notice of acceleration or other formalities of any kind, all of which are hereby expressly waived by the Borrower. 
 (b) In the case of the occurrence of an Event of Default referred to in clauses (e), (f) or (g) of Section 10.01, the Commitments shall be automatically canceled and the
principal amount then outstanding of, and the accrued interest on, the Loans and all other amounts payable by the Borrower hereunder and under the Notes (including without limitation the payment of cash collateral to secure the LC Exposure as

Agent to collect directly any such Distributions constitute in any way a waiver, remission or release of any of its rights under the Pledges, nor shall any release of any other Distributions or of any rights of Administrative Agent to collect other
Distributions thereafter. 
 (iii) Borrower will upon the instruction of Administrative Agent join with Administrative Agent
in notifying in writing to the entities responsible for making such Distributions of the existence of the Pledges, and instructing that all Distributions be paid directly to Administrative Agent for the ratable benefit of the Lenders. 
 ARTICLE XI 
 The Administrative Agent

 Section 11.01 Appointment, Powers and Immunities. Each Lender hereby irrevocably appoints and authorizes the Administrative
Agent to act as its agent hereunder and under the Security Instruments with such powers as are specifically delegated to the Administrative Agent by the terms of this Agreement and the Security Instruments, together with such other powers as are
reasonably incidental thereto. The Administrative Agent (which term as used in this sentence and in Section 11.05 and the first sentence of Section 11.06 shall include reference to its Affiliates and its and its
Affiliates’ officers, directors, employees, attorneys, accountants, experts and agents): (i) shall have no duties or responsibilities except those expressly set forth in the Loan Documents, and shall not by reason of the Loan Documents be
a trustee or fiduciary for any Lender; (ii) makes no representation or warranty to any Lender and shall not be responsible to the Lenders for any recitals, statements, representations or warranties contained in this Agreement, or in any
certificate or other document referred to or provided for in, or received by any of them under, this Agreement, or for the value, validity, effectiveness, genuineness, execution, effectiveness, legality, enforceability or sufficiency of this
Agreement, any Note or any other document referred to or provided for herein or for any failure by any of the Obligors or any other Person (other than the Administrative Agent) to perform any of its obligations hereunder or thereunder or for the
existence, value, perfection or priority of any collateral security or the financial or other condition of the Borrower, its Subsidiaries or any other obligor or guarantor; (iii) except pursuant to Section 11.07 shall not be
required to initiate or conduct any litigation of collection proceedings hereunder; and (iv) shall not be responsible for any action taken or omitted to be taken by it hereunder or under any other document or instrument referred to or provided
for herein or in connection herewith including its own ordinary negligence, except for its own gross negligence or willful misconduct. The Administrative Agent may employ agents, accountants, attorneys and experts and shall not be responsible for
the negligence or misconduct of any such agents, accountants, attorneys or experts selected by it in good faith or any action taken or omitted to be taken in good faith by it in accordance with the advice of such agents, accountants, attorneys or
experts. The Administrative Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof permitted hereunder shall have been filed with the
Administrative Agent. 
 Section 11.02 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon any
certification, notice or other communication (including any thereof by telephone, telex, telecopier, telegram or cable) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons, and
upon advice and statements of legal counsel, independent accountants and other experts selected by the Administrative Agent. 
  

 53 

 Section 11.03 Defaults. The Administrative Agent shall not be deemed to have knowledge of the
occurrence of a Default (other than the non-payment of principal of or interest on Loans or of fees or failure to reimburse for Letter of Credit drawings) unless the Administrative Agent has received notice from a Lender or the Borrower specifying
such Default and stating that such notice is a “Notice of Default”. In the event that the Administrative Agent receives such a notice of the occurrence of a Default, the Administrative Agent shall give prompt notice thereof
to the Lenders. In the event of a payment Default, the Administrative Agent shall give each Lender prompt notice of each such payment Default. 
 Section 11.04 Rights as a Lender. With respect to its Commitments and the Loans made by it and its participation in the issuance of Letters of Credit, Wachovia Bank, National Association (and any successor acting as Administrative
Agent) in its capacity as a Lender hereunder shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not acting as the Administrative Agent, and the term “Lender” or
“Lenders” shall, unless the context otherwise indicates, include the Administrative Agent in its individual capacity. Wachovia Bank, National Association (and any successor acting as Administrative Agent) and its Affiliates may
(without having to account therefor to any Lender) accept deposits from, lend money to and generally engage in any kind of banking, trust or other business with the Obligors (and any of their Affiliates) as if it were not acting as the
Administrative Agent, and Wachovia Bank, National Association and its Affiliates may accept fees and other consideration from the Obligors for services in connection with this Agreement or otherwise without having to account for the same to the
Lenders. 
 Section 11.05 Indemnification. The Lenders agree to indemnify the Administrative Agent and the Issuing Bank ratably in
accordance with their percentage shares for the indemnity matters as described in Section 12.03 to the extent not indemnified or reimbursed by the Obligors under Section 12.03, but without limiting the
obligations of the Obligors under said Section 12.03 and for any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever
which may be imposed on, incurred by or asserted against the Administrative Agent or the Issuing Bank in any way relating to or arising out of: (i) this Agreement, the Security Instruments or any other documents contemplated by or referred to
herein or the transactions contemplated hereby, but excluding, unless a Default has occurred and is continuing, normal administrative costs and expenses incident to the performance of its agency duties hereunder or (ii) the enforcement of any
of the terms of this Agreement, any Security Instrument or of any such other documents; WHETHER OR NOT ANY OF THE FOREGOING SPECIFIED IN THIS SECTION 11.05 ARISES FROM THE SOLE OR CONCURRENT NEGLIGENCE OF THE ADMINISTRATIVE
AGENT OR THE ISSUING BANK, provided that no Lender shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the Administrative Agent or the Issuing Bank. 
 Section 11.06 Non-Reliance on Administrative Agent and other Lenders. Each Lender acknowledges and agrees that it has, independently and without
reliance on the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Obligors and its decision to enter into this Agreement, and that it will,
independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking
action under this Agreement. The Administrative Agent shall not be required to keep itself informed as to the performance or observance by the Obligors of this Agreement, the Notes, the Security Instruments or any other document referred to or
provided for herein or to inspect the properties or books of the Obligors. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder 
  

 54 

 
(including, without limitation, those materials delivered to the Administrative Agent pursuant to Section 8.01), the Administrative Agent
shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Obligors (or any of their Affiliates) which may come into the possession of the
Administrative Agent or any of its Affiliates. In this regard, each Lender acknowledges that Thompson & Knight, LLP is acting in this transaction as special counsel to the Administrative Agent only, except to the extent otherwise expressly
stated in any legal opinion or any Loan Document. Each Lender will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein. 
 Section 11.07 Action by Administrative Agent. Except for action or other matters expressly required of the Administrative Agent hereunder, the
Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall (i) receive written instructions from the Required Lenders, as applicable (or all of the Lenders as expressly required by
Section 12.04), specifying the action to be taken, and (ii) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take
any such action. The instructions of the Required Lenders, as applicable (or all of the Lenders as expressly required by Section 12.04), and any action taken or failure to act pursuant thereto by the Administrative Agent shall be
binding on all of the Lenders. If a Default has occurred and is continuing, the Administrative Agent shall take such action with respect to such Default as shall be directed by the Required Lenders, as applicable (or all of the Lenders as required
by Section 12.04), in the written instructions (with indemnities) described in this Section 11.07, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the Administrative Agent be
required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement and the Security Instruments or applicable law. 
 Section 11.08 Resignation or Removal of Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as
provided below, the Administrative Agent may resign at any time by giving notice thereof to the Lenders and the Borrower, and the Administrative Agent may be removed at any time with or without cause by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within
thirty (30) days after the retiring Administrative Agent’s giving of notice of resignation or the Required Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders,
appoint a successor Administrative Agent. Upon the acceptance of such appointment hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon 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. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative

obligations outstanding and asserted against the indemnitor at that time, including the maximum potential claims against the Indemnified Party to be indemnified pursuant to this Section 12.03. 
 (c) In the case of any indemnification hereunder, the Administrative Agent or Lender, as appropriate shall give notice to the Obligors of
any such claim or demand being made against the Indemnified Party and the Obligors shall have the non-exclusive right to join in the defense against any such claim or demand provided that if any Obligor provides a defense, the Indemnified Party

 Section 12.04 Amendments, Etc. No amendment or waiver of any provision of this
Agreement or the Notes or any other Loan Document (excluding Hedging Agreements), nor consent to any departure by the Borrower or any other Obligor therefrom, shall in any event be effective unless the same shall be in writing and signed by the
Required Lenders (or by the Administrative Agent on their behalf upon its receipt of the consent thereof) and the Borrower or the applicable Obligor, as the case may be, and acknowledged by the Administrative Agent, and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no such amendment, waiver or consent shall:

Section 6.02, without the written consent of each Lender (other than any Lender that is, at such time, a Defaulting Lender);

any other Loan Document, or change the manner of computation of any financial ratio (including any change in any applicable defined term) used in determining the Applicable Margin that would result in a reduction of any interest rate on any Loan or
any fee payable hereunder without the written consent of each Lender directly affected thereby; provided, however, that only the written consent of the Required Lenders shall be necessary (i) to amend the definition of
“Post-Default Rate” or to waive any obligation of the Borrower to pay interest at the Post-Default Rate or (ii) to amend any financial covenant hereunder (or any defined term used therein) even if the effect of such
amendment would be to reduce the rate of interest on any Loan or advance under any Letter of Credit or to reduce any fee payable hereunder; 
 (e) change (i) any provision of Section 4.05(b) that would alter the pro rata sharing of payments required thereby or this Section 12.04 without the written consent of each
Lender, (ii) the definition of “Required Lenders” without the written consent of each Lender, (iii) the definition of “Percentage Share” without the written consent of each Lender, or

 Section 12.05 Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. 
 Section 12.06 Assignments and Participations. 
 (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, except that neither the Borrower nor any other Obligor may assign or otherwise transfer any of its rights or
obligations hereunder without the prior written consent of the Administrative Agent and each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with
the provisions of subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section, or (iii) by way of pledge or assignment
of a security interest subject to the restrictions of subsection (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied,
shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in subsection (d) 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) Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this
Agreement (including all or a portion of its Commitment and the Loans (including for purposes of this subsection (b), participations in Letters of Credit) at the time owing to it); provided, that: 
 (i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time
owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the
Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the
Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than One Million Dollars ($1,000,000) unless each of the Administrative Agent and, so long as no Event
of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed); 
 (ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned;

 (iii) any assignment of a Commitment must be approved by the Administrative Agent and the Issuing Bank unless the Person
that is the proposed assignee is itself a Lender (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); and 
  

 60 

 (iv) 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 Three Thousand Five Hundred Dollars ($3,500), and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire. 
 Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c) of
this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the
rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of
an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 4.06, 5.01,
5.04, and 12.03 with respect to facts and circumstances occurring prior to the effective date of such assignment. Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee Lender. Any
assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection 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 subsection (d) of this Section. 
 (c) The Administrative Agent, acting solely for this
purpose as an agent of the Borrower, shall maintain at its Principal Office a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal
amounts of the Loans and LC Exposure 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 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
each of the Borrower and the Issuing Bank at any reasonable time and from time to time upon reasonable prior notice. 
 (d)
Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries)
(each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans (including such Lender’s participations in
Letters of Credit, if applicable) owing to it); provided, that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance
of such obligations and (iii) the Borrower, the Administrative Agent, the Lenders and the Issuing Bank 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, waiver or other modification described in the first proviso to Section 12.04 that affects such Participant. Subject to subsection (e) of this Section, the 

  

 61 

 
Borrower agrees that each Participant shall be entitled to the benefits of Sections 4.06, 5.01 and 5.05 to the same extent as if
it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 4.05 as
though it were a Lender, provided, that such Participant agrees to be subject to Section 4.01 as though it were a Lender. 
 (e) A Participant shall not be entitled to receive any greater payment under Section 4.06, 5.01 or 5.05 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 4.06 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 4.06 as though it
were a Lender. 
 (f) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights
under this Agreement (including under its Note, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided, that no such pledge or assignment shall release such Lender
from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 
 (g) The
words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form,
each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the
Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act. 
 (h) Notwithstanding anything to the contrary contained herein, if at any time Wachovia assigns all of its Commitment and Loans pursuant to
subsection (b) above, Wachovia may, upon 30 days’ notice to the Borrower and the Lenders, resign as Issuing Bank. In the event of any such resignation as Issuing Bank, the Borrower shall be entitled to appoint from among the Lenders a
successor Issuing Bank hereunder; provided however, that no failure by the Borrower to appoint any such successor shall affect the resignation of Wachovia as Issuing Bank. If Wachovia resigns as Issuing Bank, it shall retain all the rights
and obligations of the Issuing Bank hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as Issuing Bank and all LC Exposure with respect thereto (including the right to require the Lenders to make
Base Rate Loans or fund risk participations in unreimbursed amounts pursuant to Section 2.09(c)). 
 Section 12.07
Invalidity. In the event that any one or more of the provisions contained in any of the Loan Documents shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not
affect any other provision of the Notes, this Agreement or any other Loan Document. 
 Section 12.08 Counterparts. This Agreement may
be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the parties hereto may execute this Agreement by signing any such counterpart. 
  

 62 

 Section 12.09 References, Use of Word “Including”. The words “herein,”
“hereof,” “hereunder” and other words of similar import when used in this Agreement refer to this Agreement as a whole, and not to any particular article, section or subsection. Any reference herein to a Section or
Article shall be deemed to refer to the applicable Section or Article of this Agreement unless otherwise stated herein. Any reference herein to an exhibit, schedule, or other attachment shall be deemed to refer to the applicable exhibit, schedule,

 Section 12.10 Survival. The obligations of the parties under Section 4.06, Article V, and
Sections 11.05 and 12.03 shall survive the repayment of the Loans and the termination of the Commitments. To the extent that any payments on the Indebtedness or proceeds of any collateral are subsequently
invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Indebtedness so
satisfied shall be revived and continue as if such payment or proceeds had not been received and the Administrative Agent’s and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each Security
Instrument shall continue in full force and effect. In such event, each Security Instrument shall be automatically reinstated and the Obligors shall take such action as may be reasonably requested by the Administrative Agent and the Lenders to
effect such reinstatement. 
 Section 12.11 Captions. Captions and section headings appearing herein are included solely for
convenience of reference and are not intended to affect the interpretation of any provision of this Agreement. 
 Section 12.12 NO ORAL
AGREEMENTS. The Loan Documents embody the entire agreement and understanding between the parties and supersede all other agreements and understandings between such parties relating to the subject matter hereof and thereof. The Loan Documents
represent the final agreement between the parties and may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the parties. There are no unwritten oral agreements between the parties. 
 Section 12.13 GOVERNING LAW, SUBMISSION TO JURISDICTION. 
 (a) This Agreement and the Notes shall be governed by, and construed in accordance with, the Law of the State of New York (without
giving effect to its conflicts of law rules other than Section 5-1401 of the New York General Obligation Law) and applicable federal law; and the Administrative Agent and the Lenders shall retain all rights arising under federal law.

 (b) Any legal action or proceeding with respect to the Loan Documents shall be brought in the courts of the State of
New York or of the United States of America for the Southern District of New York, and, by execution and delivery of this Agreement, the Borrower and each Guarantor hereby accepts for itself and (to the extent permitted by Law) in respect of its
Property, generally and unconditionally, the jurisdiction of the aforesaid courts. Each of the Borrower and each Guarantor hereby irrevocably waives any objection, including, without limitation, any objection to the laying of venue or based on the
grounds of forum non conveniens, which it may now or hereafter have to the bringing of any such action or proceeding in such respective jurisdictions. This submission to jurisdiction is non-exclusive and does not preclude the
Administrative Agent or any Lender from obtaining jurisdiction over the Borrower or any Guarantor in any court otherwise having jurisdiction. 
  

 63 

 (c) The Borrower and each Guarantor hereby designates CT
Corporation System located at 111 Eighth Avenue, 13th Floor, New York, New York, 10011, or
other agent acceptable to the Administrative Agent, as the designee, appointee and agent of the Borrower and each Guarantor to receive, for and on behalf of the Borrower and each Guarantor, service of process in such respective jurisdictions in any
legal action or proceeding with respect to the Loan Documents. It is understood that a copy of such process served on such Administrative Agent will be promptly forwarded by overnight courier to the Borrower and the relevant Guarantor at their
addresses set forth under its signature below, but the failure of the Borrower or such Guarantor to receive such copy shall not affect in any way the service of such process. The Borrower and each Guarantor further irrevocably consents to the
service of process of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to each of the Borrower and any Guarantor at its said address, such service to
become effective thirty (30) days after such mailing. 
 (d) Nothing herein shall affect the right of the
Administrative Agent or any Lender or any holder of a Note to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against the Borrower or any Guarantor in any other jurisdiction. 

(e) The Borrower, each Guarantor and each Lender hereby (i) irrevocably and unconditionally waive, to the fullest extent
permitted by law, trial by jury in any legal action or proceeding relating to this Agreement or any Security Instrument and for any counterclaim therein; (ii) irrevocably waive, to the maximum extent not prohibited by law, any right it may have
to claim or recover in any such litigation any special, exemplary, punitive or consequential damages, or damages other than, or in addition to, actual damages; (iii) certify that no party hereto nor any representative of the Administrative
Agent or counsel for any party hereto has represented, expressly or otherwise, or implied that such party would not, in the event of litigation, seek to enforce the foregoing waivers, and (iv) acknowledge that it has been induced to enter into
this agreement, the security instruments and the transactions contemplated hereby and thereby by, among other things, the mutual waivers and certifications contained in this Section 12.13. 
 Section 12.14 USA PATRIOT Act Notice. Each Lender that is subject to the Act (as hereinafter defined) and the Administrative Agent (for itself and
not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain,
verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in
accordance with the Act. 
 Section 12.15 Interest. It is the intention of the parties hereto to conform strictly to applicable usury
laws regarding the use, forbearance or detention of the indebtedness evidenced by this Agreement, the Notes and the other Loan Documents, whether such laws are now or hereafter in effect, including the laws of the United States of America or any
other jurisdiction whose laws are applicable, and including any subsequent revisions to or judicial interpretations of those laws, in each case to the extent they are applicable to this Agreement, the Notes and the other Loan Documents (the
“Applicable Usury Laws”). Accordingly, if any acceleration of the maturity of the Notes or any payment by Borrower or any other Person produces a rate in excess of the Highest Lawful Rate or otherwise results in Borrower or
such other Person being deemed to have paid any interest in excess of the Maximum Amount, as hereinafter 

  

 64 

 
defined, or if any Lender shall for any reason receive any unearned interest in violation of any Applicable Usury Laws, or if any transaction contemplated
hereby would otherwise be usurious under any Applicable Usury Laws, then, in that event, regardless of any provision contained in this Agreement or any other Loan Document or other agreement or instrument executed or delivered in connection
herewith, the provisions of this Section 12.15 shall govern and control, and neither Borrower nor any other Person shall be obligated to pay, or apply in any manner to, any amount that would be excessive interest. No Lender shall
ever be deemed to have contracted for or be entitled to receive, collect, charge, reserve or apply as interest on any Loan (whether termed interest therein or deemed to be interest by judicial determination or operation of law), any amount in excess
of the Highest Lawful Rate, and, in the event that such Lender ever receives, collects, or applies as interest any such excess, such amount which would be excessive interest shall be applied as a partial prepayment of principal and treated hereunder
as such, and, if the principal amount of the applicable Loans are paid in full, any remaining excess shall forthwith be paid to Borrower. In determining whether or not the interest contracted for, received, collected, charged reserved, paid or
payable, including under any specific contingency, exceeds the Highest Lawful Rate, Borrower and each Lender shall, to the maximum extent permitted under applicable law, (i) characterize any non-principal payment (other than payments which are
expressly designated as interest payments hereunder) as an expense or fee rather than as interest, (ii) exclude voluntary pre-payments and the effect thereof, and (iii) amortize and spread the total amount of interest throughout the entire
stated term of the Loans so that the interest rate is uniform throughout such term; provided that if the Loans are paid in full prior to the end of the full contemplated term hereof, and if the interest received for the actual period of
existence thereof exceeds the Highest Lawful Rate, if any, then the Lenders shall refund to Borrower the amount of such excess, or credit the amount of such excess against the aggregate unpaid principal balance of all Loans made by Lender. As used
herein, the term “Maximum Amount” means the maximum nonusurious amount of interest which may be lawfully contracted for, reserved, charged, collected or received by Lender in connection with the indebtedness evidenced by this
Agreement, the Notes and other Loan Documents under all Applicable Usury Laws. Texas Finance Code, Chapter 346, which regulates certain revolving loan accounts and revolving tri-party accounts, shall not apply to any revolving loan accounts created
under, or apply in any manner to, the Note, this Agreement or the other Loan Documents. 
 Section 12.16 Confidentiality. In the event
that the Borrower provides to the Administrative Agent or the Lenders written confidential information belonging to the Borrower, if the Borrower shall denominate such information in writing as “confidential,” the Administrative
Agent and the Lenders shall thereafter maintain such information in confidence in accordance with the standards of care and diligence that each utilizes in maintaining its own confidential information. This obligation of confidence shall not apply
to such portions of the information which (i) are in the public domain, (ii) hereafter become part of the public domain without the Administrative Agent or the Lenders breaching their obligation of confidence to the Borrower,
(iii) are previously known by the Administrative Agent or the Lenders from some source other than the Borrower, (iv) are hereafter developed by the Administrative Agent or the Lenders without using the Borrower’s information,
(v) are hereafter obtained by or available to the Administrative Agent or the Lenders from a third party who owes no obligation of confidence to the Borrower with respect to such information or through any other means other than through
disclosure by the Borrower, (vi) are disclosed with the Borrower’s consent, (vii) must be disclosed either pursuant to any Governmental Requirement or to Persons regulating the activities of the Administrative Agent or the Lenders,
provided Administrative Agent and Lenders shall endeavor to provide notice to the Borrower as soon as practicable in the event Borrower desires to enjoin the disclosure of such information, however, failure of Administrative Agent or Lenders to
provide such prior notice to Borrower shall not give rise to any claim or cause of action by Borrower or any Obligor against Administrative Agent or such Lenders, or (viii) as may be required by law or regulation or order of any Governmental
Authority in any judicial, arbitration or governmental proceeding. Further, the Administrative Agent or a Lender may disclose any

such information to any other Lender, any independent petroleum engineers or consultants, any independent certified public accountants, any legal counsel
employed by such Person in connection with this Agreement or any Security Instrument, including without limitation, the enforcement or exercise of all rights and remedies thereunder, or any assignee or participant (including prospective assignees
and participants) in the Loans; provided, however, that the Administrative Agent or the Lenders shall receive a confidentiality agreement from the Person to whom such information is disclosed such that said Person shall have the same obligation to
maintain the confidentiality of such information as is imposed upon the Administrative Agent or the Lenders hereunder. Notwithstanding anything to the contrary provided herein, this obligation of confidence shall cease three (3) years from the
date the information was furnished, unless the Borrower requests in writing at least thirty (30) days prior to the expiration of such three year period, to maintain the confidentiality of such information for an additional three year period.
The Borrower waives any and all other rights it may have to confidentiality as against the Administrative Agent and the Lenders arising by contract, agreement, statute or law except as expressly stated in this Section 12.16.
