purchase such Defaulting First Lien Secured Party’s First Lien Obligations for resale to the Second Lien Secured Parties and (C) in all cases, the First Lien Administrative Agent and each First Lien Secured Party complying with the terms

without warranty or representation or recourse (except for representations and warranties required to be made by assigning lenders pursuant to the Assignment and Assumption (as such term is defined in the Second Lien Credit Agreement)), all (but not
less than all) of the Second Lien Obligations; provided that (x) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority having jurisdiction, and (y) the First Lien
Secured Parties shall have paid to the Second Lien Administrative Agent, for the account of the Second Lien Secured Parties, in immediately available funds, an amount equal to 100% of the principal of the Second Lien Obligations plus all accrued and
unpaid interest thereon plus all accrued and unpaid fees and expenses plus all the other Second Lien Obligations then outstanding (which shall include a premium in an amount equal to the Prepayment Fee as set forth in Section 3.04(d) of the
Second Lien Credit Agreement). In order to effectuate the foregoing, the Second Lien Administrative Agent shall calculate, upon the written request of the First Lien Administrative Agent from time to time, the amount in cash that would be necessary
so to purchase the Second Lien Obligations. Each Second Lien Secured Party will retain all rights to indemnification provided by the Borrower in the relevant Second Lien Loan Documents for all claims and other amounts relating to periods prior to

Agent and each Second Lien Secured Party complying with the terms of this Section 3.01(e) shall not be deemed to be in default of this Agreement or otherwise be deemed liable for any action or inaction of any Defaulting Second Lien
Secured Party; provided that nothing in this last sentence of this Section 3.01(e) shall (x) require the First Lien Secured Parties to purchase less than all of the Second Lien Obligations or (y) prohibit the First Lien Secured
Parties from purchasing less than all of the Second Lien Obligations if a Second Lien Secured Party becomes a Defaulting Second Lien Secured Party.

petition for or vote in favor of any resolution for, any such action or proceeding, after a period of 180 days has elapsed since the date on which the Second Lien Administrative Agent has delivered to the First Lien Administrative Agent written
notice of the acceleration of the Indebtedness then outstanding under the Second Lien Credit Agreement (the “Standstill Period”), so long as such payment default has not been cured or waived and such acceleration, if
applicable, has not been rescinded; provided further, however, that (A) notwithstanding the expiration of the Standstill Period or anything herein to the contrary, except for Second Lien Permitted Actions, in no event shall the Second
Lien Administrative Agent or any other Second Lien Secured Party commence an Enforcement Action with respect to any Collateral, or commence, join with any Person in commencing, or petition for or vote in favor of any resolution for, any such
Enforcement Action, if the First Lien Administrative Agent or any other First Lien Secured Party shall have commenced, and shall be diligently pursuing (or shall have sought or requested relief from or modification of the automatic stay or any other
stay in any Insolvency Proceeding to enable the commencement and pursuit thereof), an Enforcement Action with respect to any portion of the Collateral (prompt written notice thereof to be given to the Second Lien Administrative Agent by the First
Lien Administrative Agent), and (B) after the expiration of the Standstill Period, so long as neither the First Lien Administrative Agent nor the First Lien Secured Parties have commenced any action to enforce their Lien on any portion of the
Collateral, in the event that and for so long as the Second Lien Secured Parties (or the Second Lien Administrative Agent on their behalf) have commenced actions to enforce their Lien with respect to all or any material portion of the Collateral to
the extent permitted hereunder and are diligently pursuing such actions (it being understood that this clause shall not constitute a waiver by the First Lien 

  
 15 

 
Administrative Agent or the other First Lien Secured Parties of the provisions of Article VI), neither the First Lien Secured Parties nor the First Lien Administrative Agent shall take any
action of a similar nature with respect to such Collateral; provided that all other provisions of this Agreement (including the turnover provisions of Article IV) are complied with; and provided further that the Standstill Period
shall be tolled for so long as any automatic stay or any other stay or other order prohibiting the exercise of remedies by the First Lien Administrative Agent or the First Lien Secured Parties with respect to the Collateral is in effect by operation
of law or has been entered into by a court of competent jurisdiction; 
 (ii) will not contest, protest or object
to any Enforcement Action brought by the First Lien Administrative Agent or any other First Lien Secured Party, including any Enforcement Action by any First Lien Secured Party relating to the Collateral so long as Second Priority Liens attach to
the proceeds thereof subject to the relative priorities set forth in Section 2.01; 
 (iii) subject to the
rights of the Second Lien Secured Parties under clause (i) above, will not object to the forbearance by the First Lien Administrative Agent or any other First Lien Secured Party from commencing or pursuing any Enforcement Action with respect to
the Collateral; 
 (iv) will not, so long as the Discharge of First Lien Obligations has not occurred and except
for Second Lien Permitted Actions, take or receive any Collateral, or any proceeds thereof or payment with respect thereto, in connection with the exercise of any Enforcement Action with respect to any Collateral or in connection with any insurance
policy award under a policy of insurance relating to any Collateral or any condemnation award (or deed in lieu of condemnation) relating to any Collateral; 
 (v) will not, except for Second Lien Permitted Actions, take any action that would, or could reasonably be expected to, hinder, in any manner, any exercise of remedies under the First Lien Loan Documents,
including any Disposition of any Collateral, whether by foreclosure or otherwise; 
 (vi) will not, except for
Second Lien Permitted Actions, object to the manner in which the First Lien Administrative Agent or any other First Lien Secured Party may seek to enforce or collect the First Lien Obligations or the First Priority Liens, regardless of whether any
action or failure to act by or on behalf of the First Lien Administrative Agent or any other First Lien Secured Party is, or could be, adverse to the interests of the Second Lien Secured Parties, and will not assert, and hereby waive, to the fullest
extent permitted by law, any right to demand, request, plead or otherwise assert or claim the benefit of any marshalling, appraisal, valuation or other similar right that may be available under applicable law with respect to the Collateral or any
similar rights a junior secured creditor may have under applicable law; and 

  
 16 

 (vii) will not attempt, directly or indirectly, whether by judicial
proceeding or otherwise, to challenge or question the validity or enforceability of any First Lien Obligation or any First Lien Security Instrument, including this Agreement, or the validity or enforceability of the priorities, rights or obligations
established by this Agreement; 
 provided, however, that, in the case of clauses (i) through (vii) above, it is the intention of the
parties hereto that the Liens granted to secure the Second Lien Obligations of the Second Lien Secured Parties shall attach to any proceeds remaining from any such Enforcement Action taken by the First Lien Administrative Agent or any First Lien
Secured Party in accordance with this Agreement after application of such proceeds to Discharge the First Lien Obligations. 

Section 3.03 Rights as Unsecured Creditors. The Second Lien Administrative Agent and the other Second Lien Secured
Parties may, in accordance with the terms of the Second Lien Loan Documents and applicable law, enforce rights and exercise remedies against the Borrower and any Guarantor as unsecured creditors (other than initiating or joining in an involuntary
case or proceeding under the Bankruptcy Code prior to the end of the Standstill Period); provided that no such action is otherwise inconsistent with the terms of this Agreement. Nothing in this Agreement shall prohibit the acceleration of the
Second Lien Obligations, the receipt by the Second Lien Administrative Agent or any other Second Lien Secured Party of the required payments of principal, premium, interest, fees and other amounts due under the Second Lien Loan Documents so long as
such receipt is not the direct or indirect result of the enforcement or exercise by the Second Lien Administrative Agent or any other Second Lien Secured Party of rights or remedies as a secured creditor (including any right of setoff) or
enforcement in contravention of this Agreement of any Second Priority Lien (including any judgment Lien resulting from the exercise of remedies available to an unsecured creditor). 

Section 3.04 Automatic Release of Second Priority Liens. 

(a) If, in connection with (i) any Disposition of any Collateral permitted under the terms of the First Lien Loan Documents other
than pursuant to an Enforcement Action or (ii) an Enforcement Action, the First Lien Administrative Agent, for itself and on behalf of the other First Lien Secured Parties, (x) releases any of the First Priority Liens, or (y) releases
any Guarantor from its obligations under its guarantee of the First Lien Obligations (in each case, a “Release”), other than any such Release granted following the Discharge of First Lien Obligations, then the Second Priority
Liens on such Collateral, and the obligations of such Guarantor under its guarantee of the Second Lien Obligations, shall be automatically, unconditionally and simultaneously released, and the Second Lien Administrative Agent shall, for itself and
on behalf of the other Second Lien Secured Parties, promptly execute and deliver to the First Lien Administrative Agent, the relevant Grantor or such Guarantor such termination statements, releases and other documents as the First Lien
Administrative Agent or the relevant Grantor or Guarantor may reasonably request to effectively confirm such Release; provided that, (i) in the case of a Disposition of Collateral (other than any such Disposition in connection with an

  
 17 

 
Enforcement Action taken in connection with the First Lien Obligations with respect to the Collateral), the Second Priority Liens shall not be so released if such Disposition is not permitted
under the terms of the Second Lien Credit Agreement (other than solely as the result of the existence of a default or event of default under the Second Lien Loan Documents), and (ii) any proceeds received from such Disposition in connection
with an Enforcement Action taken in connection with the First Lien Obligations with respect to the Collateral shall be applied by the First Lien Administrative Agent to the First Lien Obligations. 

(b) Until the Discharge of First Lien Obligations occurs, the Second Lien Administrative Agent, for itself and on behalf of each other
Second Lien Secured Party, hereby appoints the First Lien Administrative Agent, and any officer or agent of the First Lien Administrative Agent, with full power of substitution, as the attorney-in-fact of each Second Lien Secured Party for the
purpose of carrying out the provisions of this Section 3.04 and taking any action and executing any instrument that the First Lien Administrative Agent may deem necessary or advisable to accomplish the purposes of this
Section 3.04 (including any endorsements or other instruments of transfer or release), which appointment is irrevocable and coupled with an interest. 
 Section 3.05 Automatic Release of First Priority Liens. If, in connection with a sale of Collateral for fair market value for cash pursuant to an Enforcement Action with respect to such
Collateral after the expiration of the Standstill Period that is permitted in accordance with clause (B) of the second proviso to Section 3.02(a)(i), including any Disposition of Collateral, the Second Lien Administrative Agent, for
itself and on behalf of the other Second Lien Secured Parties, (x) releases any of the Second Priority Liens, or (y) releases any Guarantor from its obligations under its guarantee of the Second Lien Obligations (in each case, a
“Second Lien Release”), then upon the closing of such sale the First Lien Administrative Agent shall, for itself and on behalf of the other First Lien Secured Parties, promptly execute and deliver to the Second Lien
Administrative Agent such termination statements and releases as shall be reasonably requested by the Second Lien Administrative Agent to release the First Priority Liens on such Collateral and to release the obligations of such Guarantor under its
guarantee of the First Lien Obligations; provided that so long as the Discharge of First Lien Obligations has not occurred, the proceeds of such sale shall be delivered to the First Lien Administrative Agent for the benefit of the First Lien
Secured Parties, and any payments with respect to such Second Lien Release that are received by the Second Lien Administrative Agent or any other Second Lien Secured Party, shall be segregated and held in trust and forthwith transferred or paid over
to the First Lien Administrative Agent for the benefit of the First Lien Secured Parties, in accordance with Section 4.02. 
 Section 3.06 Notice of Exercise of Second Liens. Each Second Lien Lender agrees that upon termination of the Standstill Period or such longer period as provided in
Section 3.02(a) if any Second Lien Lender or the Second Lien Administrative Agent or other representative of such Second Lien Lender intends to commence any Enforcement Action, then such Second Lien Lender or the Second Lien
Administrative Agent or other representative shall first deliver notice thereof in writing to the First Lien Administrative Agent both (i) not less than ten (10) days prior to taking any such Enforcement Action, and (ii) within three
(3) days after such Enforcement Action is taken. Such notices may be given during the Standstill Period. 

  
 18 

 Section 3.07 Insurance and Condemnation Awards. So long as the
Discharge of First Lien Obligations has not occurred, the First Lien Administrative Agent and the other First Lien Secured Parties shall have the exclusive right, subject to the rights of the Grantors under the First Lien Loan Documents, to settle
and adjust claims in respect of Collateral under policies of insurance covering Collateral and to approve any award granted in any condemnation or similar proceeding, or any deed in lieu of condemnation, in respect of the Collateral. All proceeds of
any such policy and any such award, or any payments with respect to a deed in lieu of condemnation, shall (a) first, prior to the Discharge of First Lien Obligations and subject to the rights of the Grantors under the First Lien Loan Documents,
be paid to the First Lien Administrative Agent for the benefit of First Lien Secured Parties pursuant to the terms of the First Lien Loan Documents, (b) second, after the Discharge of First Lien Obligations and subject to the rights of the
Grantors under the Second Lien Loan Documents, be paid to the Second Lien Administrative Agent for the benefit of the Second Lien Secured Parties pursuant to the terms of the Second Lien Loan Documents, and (c) third, if no Second Lien
Obligations are outstanding, be paid to the owner of the subject property, such other Person as may be entitled thereto or as a court of competent jurisdiction may otherwise direct. Until the Discharge of First Lien Obligations has occurred, if the
Second Lien Administrative Agent or any other Second Lien Secured Party shall, at any time, receive any proceeds of any such insurance policy or any such award or payment, it shall transfer and pay over such proceeds to the First Lien Administrative
Agent in accordance with Section 4.02. 
 ARTICLE IV 

PAYMENTS 

Section 4.01 Application of Proceeds. So long as the Discharge of First Lien Obligations has not occurred, and
regardless of whether an Insolvency Proceeding has been commenced, any Collateral or proceeds thereof received by the First Lien Administrative Agent in connection with any Disposition of, or collection on, such Collateral following an Enforcement
Action shall be applied by the First Lien Administrative Agent to the First Lien Obligations (including to cash collateralize such First Lien Obligations) together with the concurrent permanent reduction of any revolving credit commitment thereunder
in an amount equal to the amount of such payment. Upon the Discharge of First Lien Obligations, the First Lien Administrative Agent shall deliver to the Second Lien Administrative Agent any remaining Collateral and any proceeds thereof then held by
it in the same form as received, together with any necessary endorsements, or as a court of competent jurisdiction may otherwise direct, to be applied by the Second Lien Administrative Agent to the Second Lien Obligations. 

Section 4.02 Payment Over. So long as the Discharge of First Lien Obligations has not occurred, any Collateral,
or any proceeds thereof or payment with respect thereto (together with assets or proceeds subject to Liens referred to in the final 

  
 19 

 
sentence of Section 2.03), received by the Second Lien Administrative Agent or any other Second Lien Secured Party in connection with any Disposition of, or collection on, such
Collateral upon the enforcement or the exercise of any right or remedy (including any right of setoff) with respect to the Collateral, shall be segregated and held in trust and forthwith transferred or paid over to the First Lien Administrative
Agent for the benefit of the First Lien Secured Parties in the same form as received, together with any necessary endorsements, or as a court of competent jurisdiction may otherwise direct. Until the Discharge of First Lien Obligations occurs, the
Second Lien Administrative Agent, for itself and on behalf of each other Second Lien Secured Party, hereby appoints the First Lien Administrative Agent, and any officer or agent of the First Lien Administrative Agent, with full power of
substitution, the attorney-in-fact of each Second Lien Secured Party for the purpose of carrying out the provisions of this Section 4.02 and taking any action and executing any instrument that the First Lien Administrative Agent may deem
necessary or advisable to accomplish the purposes of this Section 4.02, which appointment is irrevocable and coupled with an interest. 
 Section 4.03 Certain Agreements with Respect to Unenforceable Liens. Notwithstanding anything to the contrary contained herein, if in any Insolvency Proceeding a determination is made
that any Lien encumbering any Collateral is not enforceable for any reason, then the Second Lien Administrative Agent and the Second Lien Secured Parties agree that, any distribution or recovery they may receive with respect to, or allocable to, the
value of the assets intended to constitute such Collateral or any proceeds thereof shall (for so long as the Discharge of First Lien Obligations has not occurred) be segregated and held in trust and forthwith paid over to the First Lien
Administrative Agent for the benefit of the First Lien Secured Parties in the same form as received without recourse, representation or warranty (other than a representation of the Second Lien Administrative Agent that it has not otherwise sold,
assigned, transferred or pledged any right, title or interest in and to such distribution or recovery) but with any necessary endorsements or as a court of competent jurisdiction may otherwise direct until such time as the Discharge of First Lien
Obligations has occurred. Until the Discharge of First Lien Obligations occurs, the Second Lien Administrative Agent, for itself and on behalf of each other Second Lien Secured Party, hereby appoints the First Lien Administrative Agent, and any
officer or agent of the First Lien Administrative Agent, with full power of substitution, the attorney-in-fact of each Second Lien Secured Party for the limited purpose of carrying out the provisions of this Section 4.03 and taking any
action and executing any instrument that the First Lien Administrative Agent may deem necessary or advisable to accomplish the purposes of this Section 4.03, which appointment is irrevocable and coupled with an interest. 

ARTICLE V 

BAILMENT 

Section 5.01 Bailment for Perfection of Certain Security Interests. 

(a) The First Lien Administrative Agent agrees that if it shall at any time hold a First Priority Lien on any Collateral that can be
perfected by the possession or control 

  
 20 

 
of such Collateral or of any account in which such Collateral is held, and if such Collateral or any such account is in fact in the possession or under the control of the First Lien
Administrative Agent, or of agents or bailees of the First Lien Administrative Agent (such Collateral being referred to herein as the “Pledged or Controlled Collateral”), the First Lien Administrative Agent shall, solely for
the purpose of perfecting the Second Priority Liens granted under the Second Lien Loan Documents and subject to the terms and conditions of this Article V, also hold such Pledged or Controlled Collateral as bailee for the Second Lien
Administrative Agent. The First Lien Administrative Agent shall not charge the Second Lien Secured Parties a fee for holding such Collateral as bailee pursuant hereto. 
 (b) So long as the Discharge of First Lien Obligations has not occurred, the First Lien Administrative Agent shall be entitled to deal with the Pledged or Controlled Collateral in accordance with the
terms of this Agreement and the other First Lien Loan Documents as if the Second Priority Liens did not exist until the expiration of the Standstill Period or such longer period as provided under Section 3.02(a). The obligations and
responsibilities of the First Lien Administrative Agent to the Second Lien Administrative Agent and the other Second Lien Secured Parties under this Article V shall be limited solely to holding or controlling the Pledged or Controlled
Collateral as bailee in accordance with this Article V. Without limiting the foregoing, the First Lien Administrative Agent shall have no obligation or responsibility to ensure that any Pledged or Controlled Collateral is genuine or owned by
any of the Grantors. The First Lien Administrative Agent acting pursuant to this Article V shall not, by reason of this Agreement, any other Security Instrument or any other document, have a fiduciary relationship in respect of any other
First Lien Secured Party, the Second Lien Administrative Agent or any other Second Lien Secured Party. 
 (c) Upon the Discharge
of First Lien Obligations, the First Lien Administrative Agent shall transfer the possession and control of the Pledged or Controlled Collateral, together with any necessary endorsements but without recourse or warranty (other than a representation
of the First Lien Administrative Agent that it has not otherwise sold, assigned, transferred or pledged any right, title or interest in and to such Pledged or Controlled Collateral), (i) if the Second Lien Obligations are outstanding at such
time, to the Second Lien Administrative Agent, and (ii) if no Second Lien Obligations are outstanding at such time, to the applicable Grantor or to whomever shall be entitled thereto, in each case so as to allow such Person to obtain possession
and control of such Pledged or Controlled Collateral. In connection with any transfer under clause (i) of the immediately preceding sentence, subject to the provisions of Section 5.01(d), the First Lien Administrative Agent agrees
to take all actions in its power as shall be reasonably requested by the Second Lien Administrative Agent to permit the Second Lien Administrative Agent to obtain, for the benefit of the Second Lien Secured Parties, a first priority security
interest in the Pledged or Controlled Collateral. 
 (d) The First Lien Administrative Agent shall not be required to take any
such action requested by the Second Lien Administrative Agent that the First Lien Administrative Agent in good faith believes exposes it to personal liability for expenses or other amounts unless the First Lien Administrative Agent receives an
indemnity satisfactory to it from the Second Lien Administrative Agent or Second Lien Secured Parties with respect to such action. 

  
 21 

 Section 5.02 Bailment for Perfection of Certain Security Interests – Other
Control Collateral (Second Lien Administrative Agent). Each of the Second Lien Administrative Agent, each Second Lien Lender and each First Lien Lender agrees that if it shall at any time hold a Lien on any Collateral that can be
perfected by the possession or control of such Collateral or of any account in which such Collateral is held, and if such Collateral or any such account is in fact in the possession or under the control of the Second Lien Administrative Agent, such
Second Lien Lender or such First Lien Lender or of their respective agents or bailees (such Collateral being referred to herein as the “Other Pledged or Controlled Collateral”), such Second Lien Administrative Agent, Second
Lien Lender or First Lien Lender, as applicable, shall, solely for the purpose of perfecting the First Priority Liens granted under the First Lien Loan Documents and the Second Priority Liens granted under the Second Lien Loan Documents, also hold
such Other Pledged or Controlled Collateral as bailee for the First Lien Administrative Agent and, in the case of a Second Lien Lender or a First Lien Lender, also hold such Other Pledged or Controlled Collateral as bailee for the Second Lien
Administrative Agent. No obligations shall be imposed on the Second Lien Administrative Agent, any First Lien Lender or Second Lien Lender by reason of this Section 5.02, and none of the First Lien Administrative Agent, Second Lien
Administrative Agent, First Lien Lender or Second Lien Lender shall have a fiduciary relationship in respect of any other party. No party shall be required to take any action requested by any other party that such party in good faith believes
exposes it to personal liability for expenses or other amounts unless such party receives an indemnity satisfactory to it from the party requesting action. No Second Lien Lender, First Lien Lender or Second Lien Administrative Agent shall charge the
First Lien Administrative Agent a fee for holding such Collateral as bailee pursuant hereto. 
 ARTICLE VI 

INSOLVENCY PROCEEDINGS 
 Section 6.01 Finance and Sale Matters. 
 (a) Until the
Discharge of First Lien Obligations has occurred, the Second Lien Administrative Agent, for itself and on behalf of the other Second Lien Secured Parties, agrees that, in the event of any Insolvency Proceeding, the Second Lien Secured Parties:

 (i) will not oppose or object to the use of any Collateral constituting cash collateral under
Section 363 of the Bankruptcy Code, or any comparable provision of any other Bankruptcy Law, unless the First Lien Secured Parties, or a representative authorized by the First Lien Secured Parties, shall oppose or object to such use of
cash collateral; 

  
 22 

 (ii) will not oppose or object to any post-petition financing, whether
provided by the First Lien Secured Parties or any other Person, under Section 364 of the Bankruptcy Code, or any comparable provision of any other Bankruptcy Law (a “DIP Financing”), or the Liens securing any DIP
Financing (“DIP Financing Liens”), unless the First Lien Secured Parties, or a representative authorized by the First Lien Secured Parties, shall then oppose or object to such DIP Financing or such DIP Financing
Liens, and, to the extent that such DIP Financing Liens are senior to, or rank pari passu with, the First Priority Liens, the Second Lien Administrative Agent will, for itself and on behalf of the other Second Lien Secured Parties,
subordinate the Second Priority Liens to the First Priority Liens and the DIP Financing Liens on the terms of this Agreement; provided that the foregoing shall not prevent the Second Lien Secured Parties from proposing any other DIP Financing
to any Grantors or to a court of competent jurisdiction and provided further that the foregoing shall not prohibit the Second Lien Administrative Agent or the Second Lien Secured Parties from objecting to any provisions in any DIP Financing
to the extent under a plan of reorganization providing that the DIP Financing can be rolled into an exit financing; 
 (iii) except to the extent permitted by paragraph (b) of this Section 6.01, in connection with the use of cash collateral as described in clause (i) above or a DIP Financing,
will not request adequate protection or any other relief in connection with such use of cash collateral, DIP Financing or DIP Financing Liens unless the First Lien Secured Parties are deemed by a court of competent jurisdiction to be fully secured
on the petition date of any Insolvency Proceeding and have received payment in full in cash of current post-petition interest, incurred fees and expenses, then the Second Lien Secured Parties shall not be prohibited from seeking adequate protection
in the form of payments in the amount of current post-petition interest, incurred fees and expenses or other cash payments; 
 (iv) unless the First Lien Secured Parties agree that the First Lien Secured Parties are fully secured, then the Second Lien Administrative Agent and the Second Lien Secured Parties shall not be
prohibited from seeking adequate protection in the form of additional collateral, provided the First Lien Secured Parties shall also be granted a Lien on such additional collateral as security for the First Lien Obligations and for any DIP Financing
and that any Lien on such additional collateral securing the Second Lien Obligations shall be subordinated to the Liens on such collateral securing the First Lien Obligations and any DIP Financing (and all obligations relating thereto) and to any
other Liens granted to the First Lien Secured Parties as adequate protection on the same basis as the other First Priority Liens under this Agreement and the Liens securing any DIP Financing; and 

(v) will not oppose or object to any Disposition of any Collateral free and clear of the Second Priority Liens or other
claims under Section 363 of the Bankruptcy Code, or any comparable provision of any other Bankruptcy Law, if 

  
 23 

 
the First Lien Secured Parties, or a representative authorized by the First Lien Secured Parties, shall consent to such Disposition so long as the interests of the Second Lien Secured Parties in
the Collateral (and any post-petition assets subject to adequate protection liens, if any, in favor of the Second Lien Administrative Agent) attach to the proceeds thereof, subject to the terms of this Agreement. 

(b) The Second Lien Administrative Agent, for itself and on behalf of the other Second Lien Secured Parties, agrees that no Second Lien
Secured Party shall contest, or support any other Person in contesting, (i) any request by the First Lien Administrative Agent or any other First Lien Secured Party for adequate protection or (ii) any objection, based on a claim of a lack
of adequate protection, by the First Lien Administrative Agent or any other First Lien Secured Party to any motion, relief, action or proceeding. Notwithstanding the immediately preceding sentence, if, in connection with any DIP Financing or use of
cash collateral, (A) any First Lien Secured Party is granted adequate protection in the form of a Lien on additional collateral, the Second Lien Administrative Agent may, for itself and on behalf of the other Second Lien Secured Parties, seek
or request adequate protection in the form of a Lien on such additional collateral, which Lien will be subordinated to the First Priority Liens and DIP Financing Liens on the same basis as the other Second Priority Liens are subordinated to the
First Priority Liens under this Agreement or (B) any Second Lien Secured Party is granted adequate protection in the form of a Lien on additional collateral, the First Lien Administrative Agent shall, for itself and on behalf of the other First
Lien Secured Parties, be granted adequate protection in the form of a Lien on such additional collateral that is senior to such Second Priority Lien as security for the First Lien Obligations. 

(c) Notwithstanding the foregoing, the applicable provisions of Section 6.01(a) and (b) shall only be binding on
the Second Lien Secured Parties with respect to any DIP Financing to the extent that the amount of such DIP Financing does not exceed the sum of (i) to the extent Refinanced in connection with, and included as part of, such DIP Financing, the
aggregate principal amount of the First Lien Obligations in effect immediately prior to the commencement of such Insolvency Proceeding, plus (ii) the greater of (A) $75,000,000 and (B) an amount equal to 15% of the greater of
(1) the aggregate existing principal amount of First Lien Obligations outstanding and (2) the Borrowing Base under the First Lien Credit Agreement, in each case with respect to clause (1) and (2) above, in effect immediately
prior to the commencement of such Insolvency Proceeding (provided that, for purposes of this Section 6.01(c), such “Borrowing Base” complies with the First Lien Administrative Agent’s conforming traditional
corporate banking borrowing base for oil and gas secured loan transactions (as determined by the First Lien Administrative Agent in its sole discretion), including customary mechanisms for periodic redeterminations thereof). 

Section 6.02 Relief from the Automatic Stay. The Second Lien Administrative Agent, for itself and on behalf of
the other Second Lien Secured Parties, agrees that, so long as the Discharge of First Lien Obligations has not occurred, no Second Lien Secured Party shall, without the prior written consent of the First Lien Administrative Agent, seek or request
relief from or modification of the automatic stay or any other stay in any Insolvency Proceeding in respect of any part of the Collateral, any proceeds thereof or any Second Priority Lien. 

  
 24 

 Section 6.03 Reorganization Securities. If, in any Insolvency
Proceeding, debt obligations of the reorganized debtor secured by Liens upon any Property of the reorganized debtor are distributed, pursuant to a plan of reorganization or similar dispositive restructuring plan, on account of both the First Lien
Obligations and the Second Lien Obligations, then, to the extent the debt obligations distributed on account of the First Lien Obligations and on account of the Second Lien Obligations are secured by Liens upon the same Property, the provisions of
this Agreement will survive the distribution of such debt obligations pursuant to such plan and will apply with like effect to the Liens securing such debt obligations. 
 Section 6.04 Post-Petition Interest. 
 (a) The Second Lien
Administrative Agent, for itself and on behalf of the other Second Lien Secured Parties, agrees that no Second Lien Secured Party shall oppose or seek to challenge any claim by the First Lien Administrative Agent or any other First Lien Secured
Party for allowance in any Insolvency Proceeding of First Lien Obligations consisting of post-petition interest, fees or expenses to the extent of the value of the First Priority Liens (it being understood and agreed that such value shall be
determined without regard to the existence of the Second Priority Liens on the Collateral). 
 (b) The First Lien Administrative
Agent, for itself and on behalf of the other First Lien Secured Parties, agrees that no First Lien Secured Party shall oppose or seek to challenge any claim by the Second Lien Administrative Agent or any other Second Lien Secured Party for allowance
in any Insolvency Proceeding of Second Lien Obligations consisting of post-petition interest, fees or expenses to the extent of the value of the Second Priority Liens (it being understood and agreed that such value shall be determined taking into
account the First Priority Liens on the Collateral). 
 Section 6.05 Certain Waivers by the Second Lien Secured
Parties. The Second Lien Administrative Agent, for itself and on behalf of the other Second Lien Secured Parties, waives any claim any Second Lien Secured Party may hereafter have against any First Lien Secured Party arising out of
(a) the election by any First Lien Secured Party of the application of Section 1111(b)(2) of the Bankruptcy Code, or any comparable provision of any other Bankruptcy Law, or (b) any use of cash collateral or financing
arrangement, or any grant of a security interest in the Collateral, in any Insolvency Proceeding. 
 Section 6.06
Certain Voting Matters. Each of the First Lien Administrative Agent, on behalf of the First Lien Secured Parties and the Second Lien Administrative Agent on behalf of the Second Lien Secured Parties, agrees that, without the written
consent of the other, it will not seek to vote with the other as a single class in connection with any plan of reorganization in any Insolvency Proceeding. Except as provided in this Section 6.06, nothing in this Agreement is intended,
or shall be construed, to limit the ability of the Second Lien Administrative Agent or the Second Lien Secured Parties to vote on any plan of reorganization. 

  
 25 

 Section 6.07 Separate Grants of Security and Separate Classification.
Each of the First Lien Administrative Agent, on behalf of the First Lien Secured Parties and the Second Lien Administrative Agent on behalf of the Second Lien Secured Parties, acknowledges and agrees that (a) the grants of Liens pursuant to the
First Lien Loan Documents and the Second Lien Loan Documents constitute two separate and distinct grants of Liens and (b) because of, among other things, their differing rights in the Collateral, the Second Lien Obligations are fundamentally
different from the First Lien Obligations and must be separately classified in any plan of reorganization proposed or adopted in an Insolvency Proceeding. To further effectuate the intent of the parties as provided in the immediately preceding
sentence, if it is held that the claims against the First Lien Lenders and Second Lien Lenders in respect of the Collateral constitute only one secured claim (rather than separate classes of first lien and second lien senior secured claims), then
the Second Lien Lenders hereby acknowledge and agree that all distributions shall be made as if there were separate classes of first lien and second lien senior secured claims against the Borrower and/or other Grantors in respect of the Collateral
with the effect being that (i) to the extent that the aggregate value of the Collateral is sufficient (for this purpose ignoring all claims held by the Second Lien Lenders), the First Lien Lenders shall be entitled to receive, in addition to
amounts distributed to them in respect of principal, pre-petition interest and other claims, all amounts owing in respect of post-petition interest before any distribution is made in respect of the claims held by the Second Lien Lenders and
(ii) the Second Lien Lenders hereby acknowledge and agree to turn over to the First Lien Lenders amounts otherwise received or receivable by them to the extent necessary to effectuate the intent of this sentence, even if such turnover has the
effect of reducing the claim or recovery of the Second Lien Lenders. 
 ARTICLE VII 

OTHER AGREEMENTS 
 Section 7.01 Matters Relating to Loan Documents. 
 (a) The
First Lien Loan Documents may be amended, restated, supplemented or otherwise modified in accordance with their terms, and the Indebtedness under the First Lien Credit Agreement may be Refinanced, in each case, without the consent of any Second Lien
Secured Party; provided, however, that, without the consent of the Second Lien Required Lenders, no such amendment, restatement, supplement, modification or Refinancing (or successive amendments, restatements, supplements, modifications or
Refinancings) shall (i) contravene any provision of this Agreement, (ii) result in the sum of the aggregate principal amount of all loans (which includes unreimbursed letter of credit obligations outstanding under the First Lien Loan
Documents) at such time, exceeding a Borrowing Base that complies with the First Lien Administrative Agent’s conforming traditional corporate banking borrowing base for oil and gas secured loan transactions (as determined by the First Lien
Administrative Agent in its sole discretion in accordance with its customary standards and practices then in effect), including customary mechanisms for periodic redeterminations thereof; 

  
 26 

 (b) Until the Discharge of the First Lien Obligations occurs, without the prior written
consent of the First Lien Required Lenders, no Second Lien Loan Document may be amended, restated, supplemented or otherwise modified, or entered into, or Refinanced to the extent such amendment, restatement, supplement or modification, or the terms
of such new Second Lien Loan Document, or such Refinancing would (i) contravene the provisions of this Agreement, (ii) result in the aggregate principal amount of the loans made under the Second Lien Loan Documents exceeding
$77,599,283.00, (iii) increase the “Applicable Margin” or similar component of the interest rate under the Second Lien Loan Documents by more than 200 basis points (excluding increases resulting from the accrual of interest at the
default rate) without the Borrower offering an equivalent increase in the “Applicable Margin” or similar component of the interest rate under the First Lien Loan Documents (excluding increases resulting from the accrual of interest at the
default rate) to the First Lien Administrative Agent and the First Lien Lenders, (iv) subject to the last sentence of this clause (b), add or increase any fees to the Second Lien Loan Documents by more than 50 basis points per fee or by 100
basis points in the aggregate to the fees set forth in the Second Lien Loan Documents (as in effect on the date hereof); provided that for the avoidance of doubt, the “duration fee” payable by the Borrower pursuant to the amended
and restated fee letter dated December 13, 2012 between the Borrower and the Second Lien Agent is not an addition or increase in fees under the Second Lien Loan Documents, (v) increase the two percent (2.00%) additional margin of
interest that becomes due in connection with a default, (vi) change to earlier dates any scheduled dates for payment of principal or of interest on Indebtedness under the Second Lien Loan Documents, (vii) change any default or event of
default provisions set forth in the Second Lien Loan Documents in a manner adverse to the First Lien Secured Parties, (viii) change the redemption, prepayment, repurchase, tender or defeasance provisions set forth in the Second Lien Loan
Documents in a manner that would require a redemption, prepayment, repurchase, tender or defeasance not required pursuant to the terms of the Second Lien Loan Documents as of the date hereof or in a manner otherwise adverse to First Lien Secured
Parties, (ix) add to the Second Lien Collateral other than as specifically provided by this Agreement, (x) modify any financial covenant or negative covenant to make it more restrictive than the First Lien Credit Agreement, or
(xi) otherwise materially increase the obligations of the Borrower or the other Credit Parties thereunder or confer additional rights on the Second Lien Secured Parties in a manner materially adverse to the First Lien Secured Parties. Without
prejudice to any rights of the First Lien Lenders under the First Lien Credit Agreement (including any covenants therein that may restrict such Refinancings), Indebtedness under the Second Lien Loan Documents may be Refinanced if (A) the terms
and conditions of such Refinancing Indebtedness are no less favorable in the aggregate to the First Lien Secured Parties and no less favorable in the aggregate to the Credit Parties, in each case, than the terms and conditions of the Indebtedness
then outstanding under the Second Lien Credit Agreement, (B) the final maturity and the average life to maturity of such Refinancing Indebtedness is at least equal to that of the Indebtedness then outstanding under the Second Lien Credit
Agreement, and (C) if such Refinancing Indebtedness is secured, the holders of such Refinancing Indebtedness, or a 

  
 27 

 
duly authorized agent on their behalf, agree in writing to be bound by the terms of this Agreement or a successor intercreditor agreement that is acceptable to the First Lien Administrative Agent
in its sole discretion. For the avoidance of doubt, the limitations in clause (iv) above shall not apply to any fee (i) which may be payable only to the Second Lien Administrative Agent, acting in such capacity, whether payable at one time
or in multiple installments, (ii) payable to the Second Lien Administrative Agent as a fee or original issue discount on any increase in the Commitments or the Loans under the Second Lien Credit Agreement or (iii) payable to the Second
Lien Administrative Agent and the Second Lien Lenders as an upfront fee paid in a syndication. 
 (c) Each of the Borrower and
the Second Lien Administrative Agent agrees that the Second Lien Credit Agreement and each Second Lien Security Instrument shall contain the applicable provisions set forth on Annex I hereto, or similar provisions approved by the First Lien
Administrative Agent, which approval shall not be unreasonably withheld, conditioned or delayed. Each of the Borrower and the Second Lien Administrative Agent further agrees that each Second Lien Security Instrument covering any Collateral shall
contain such other language as the First Lien Administrative Agent may reasonably request to reflect the subordination of such Second Lien Security Instrument to the First Lien Security Instrument covering such Collateral pursuant to this Agreement.

 (d) Until the Discharge of the First Lien Obligations occurs, in the event that the First Lien Administrative Agent or the
other First Lien Secured Parties and the relevant Grantor enter into any amendment, modification, waiver or consent in respect of any of the First Lien Security Instruments (other than this Agreement), then such amendment, modification, waiver or
consent shall apply automatically to any comparable provisions of the applicable Comparable Second Lien Security Instrument, in each case, without the consent of any Second Lien Secured Party and without any action by the Second Lien Administrative
Agent, the Borrower or any other Grantor; provided, that (i) no such amendment, modification, waiver or consent shall (A) remove assets subject to the Second Priority Liens or release any such Liens, except to the extent that such
release is permitted or required by Section 3.04 and provided that there is a concurrent release of the corresponding First Priority Liens, (B) amend, modify or otherwise affect the rights or duties of the Second Lien Administrative
Agent without its prior written consent, (C) permit Liens on the Collateral which are not permitted under the terms of the Second Lien Loan Documents, (D) reduce the principal of, or interest or other amounts payable on, any amount payable
under the Second Lien Credit Agreement or any Second Lien Loan Document, (E) postpone any date fixed for any payment of principal of, or interest or other amounts payable on, any amounts payable under the Second Lien Credit Agreement or any
Second Lien Loan Document, and (ii) notice of such amendment, modification waiver or consent shall have been given to the Second Lien Administrative Agent no later than the tenth Business Day following the effective date of such amendment,
modification, waiver or consent. 
 Section 7.02 Effect of Refinancing of Indebtedness under First Lien Loan
Documents. If, substantially contemporaneously with the Discharge of First Lien Obligations and subject to consent of the Second Lien Required Lenders, the Borrower 

  
 28 

 
Refinances the First Lien Obligations (including an increase thereof, or any change to the terms thereof to the extent permitted by Section 7.01 hereof) and provided that
(a) such Refinancing is permitted hereby and (b) the Borrower gives to the Second Lien Administrative Agent written notice (the “Refinancing Notice”) electing the application of the provisions of this
Section 7.02 to such Refinancing Indebtedness, then (i) such Discharge of First Lien Obligations shall automatically be deemed not to have occurred for all purposes of this Agreement, (ii) such Refinancing Indebtedness and all
other obligations under the loan documents evidencing such Indebtedness (the “New First Lien Obligations”) shall automatically be treated as First Lien Obligations for all purposes of this Agreement, including for purposes of
the Lien priorities and rights in respect of Collateral set forth herein, (iii) the credit agreement and the other loan documents evidencing such Refinancing Indebtedness (the “New First Lien Loan Documents”) shall
automatically be treated as the First Lien Credit Agreement and the First Lien Loan Documents and, in the case of New First Lien Loan Documents that are security documents, as the First Lien Security Instruments for all purposes of this Agreement,
(iv) the Administrative Agent under the New First Lien Loan Documents (the “New First Lien Administrative Agent”) shall be deemed to be the First Lien Administrative Agent for all purposes of this Agreement and
(v) the lenders under the New First Lien Loan Documents shall be deemed to be the First Lien Lenders for all purposes of this Agreement. Upon receipt of a Refinancing Notice, which notice shall include the identity of the New First Lien
Administrative Agent, the Second Lien Administrative Agent shall promptly enter into such documents and agreements (including amendments or supplements to this Agreement) as the Borrower or such New First Lien Administrative Agent may reasonably
request in order to provide to the New First Lien Administrative Agent the rights and powers contemplated hereby, in each case consistent in all material respects with the terms of this Agreement. The Borrower shall cause the agreement, document or
instrument pursuant to which the New First Lien Administrative Agent is appointed to provide that the New First Lien Administrative Agent agrees to be bound by the terms of this Agreement. In furtherance of Section 2.03, if the New First
Lien Obligations are secured by assets of the Grantors that do not also secure the Second Lien Obligations, the applicable Grantors shall promptly grant a Second Priority Lien on such assets to secure the Second Lien Obligations. 

Section 7.03 No Waiver by First Lien Secured Parties. Other than with respect to the Second Lien Permitted Actions and
as may otherwise be expressly provided herein, nothing contained herein shall prohibit or in any way limit the First Lien Administrative Agent or any other First Lien Secured Party from opposing, challenging or objecting to, in any Insolvency
Proceeding or otherwise, any action taken, or any claim made, by the Second Lien Administrative Agent or any other Second Lien Secured Party, including any request by the Second Lien Administrative Agent or any other Second Lien Secured Party for
adequate protection or any exercise by the Second Lien Administrative Agent or any other Second Lien Secured Party of any of its rights and remedies under the Second Lien Loan Documents or otherwise. 

Section 7.04 Reinstatement. If, in any Insolvency Proceeding or otherwise, all or part of any payment with
respect to the First Lien Obligations previously made shall be rescinded for any reason whatsoever, then the First Lien Obligations shall be 

  
 29 

 
reinstated to the extent of the amount so rescinded and, if theretofore terminated, this Agreement shall be reinstated in full force and effect and such prior termination shall not diminish,
release, discharge, impair or otherwise affect the Lien priorities and the relative rights and obligations of the First Lien Secured Parties and the Second Lien Secured Parties provided for herein. 

Section 7.05 Further Assurances. Each of the First Lien Administrative Agent, for itself and on behalf of the other
First Lien Secured Parties, and the Second Lien Administrative Agent, for itself and on behalf of the other Second Lien Secured Parties, and the Borrower, for itself and on behalf of its Subsidiaries that are Grantors, agrees that it will execute,
or will cause to be executed, any and all further documents, agreements and instruments, and take all such further actions, as may be required under any applicable law, or which the First Lien Administrative Agent or the Second Lien Administrative
Agent may reasonably request, to effectuate the terms of this Agreement, including the relative Lien priorities provided for herein. The parties further agree that, notwithstanding any failure to take the actions required by the immediately
preceding sentence, each Person that becomes a Grantor at any time (and any security granted by any such Person) will be subject to the provisions hereof as fully as if it constituted a Grantor party hereto and had complied with the requirements of
the immediately preceding sentence. Each Grantor agrees to cause each of its Subsidiaries formed or acquired after the date hereof to become a Grantor for all purposes of this Agreement by executing and delivering an assumption agreement in form and
substance acceptable to the First Lien Administrative Agent and the Second Lien Administrative Agent. 
 Section 7.06
Notice of Exercise of Remedies. Subject to the terms of this Agreement, each of the First Lien Administrative Agent and the Second Lien Administrative Agent shall endeavor to provide advance notice to each other of an acceleration of
any Indebtedness in respect of the First Lien Obligations or the Second Lien Obligations, as the case may be (other than with respect to any automatic accelerations thereunder); provided, however, neither party’s failure to give such notice
under this Section 7.06 shall create any claim or cause of action on the part of the other party against the party failing to give such notice for any reason whatsoever. Nothing contained in this Section 7.06 shall limit,
restrict, alleviate, or amend any notice requirement otherwise provided in this Agreement or otherwise required under applicable law.

PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.08.

of specific performance in any action which may be brought by the respective Secured Parties. 
 Section 10.11

interpreting, this Agreement. 
 Section 10.12 Counterparts. This Agreement may be executed in counterparts

Delivery of an executed signature page to this Agreement by facsimile or other electronic transmission (e.g., .pdf) shall be as effective as delivery of a manually signed counterpart of this Agreement. 

Section 10.13 Provisions Solely to Define Relative Rights. The provisions of this Agreement are and are intended

 Article III 
 Release of Liens; Hedge Novation; Insurance Proceeds 
 Section 3.1
Release of Security Interests. Upon receipt of written notice by the Collateral Agent from (a) the First Lien Administrative Agent indicating that the Master General Partner has exercised its Withdrawal Right at the instruction of the
First Lien Administrative Agent pursuant to the Senior Credit Agreement or (b), to the extent not prohibited under the Parent Intercreditor Agreement, the Second Lien Administrative Agent indicating that the Master General Partner has exercised its
Withdrawal Right at the instruction of the Second Lien Administrative Agent pursuant to the Second Lien Credit Agreement, the Collateral Agent, on behalf of the Hedging Facility Secured Parties, shall, subject to Section 3.2, release its
Lien on the applicable Withdrawal Right Interest contemporaneously with its withdrawal from the applicable Participating Partnership; provided such withdrawal occurs in accordance with the Organizational Documents of such Participating Partnership.
The Collateral Agent shall (at the Master General Partner’s sole cost and expense), upon the written request of the Master General Partner promptly deliver to the Master General Partner any UCC termination statements, mortgage releases and
other documentation as the Master General Partner may reasonably request to evidence the termination and release of the Lien on such Withdrawal Right Interest. 
 Section 3.2 Hedge Novation. Contemporaneously with the withdrawal of any Withdrawal Right Interest in accordance with Section 3.1, each Participating Partnership and each Hedge
Provider party to any Hedge Transaction that is secured by such Withdrawal Right Interest shall novate a portion of each such Hedge Transaction to the Master General Partner to reflect that any rights and obligations arising under any such Hedge
Transaction in respect of the notional volumes of the production attributable to the Withdrawal Right Interest shall cease to be rights and obligations of such Participating Partnership and shall no longer be secured pursuant to the Hedging Facility
Agreement, but shall be primary obligations of the Master General Partner. Such novation shall be effected pursuant to the 2004 ISDA Novation Definitions and a confirmation substantially in the form of Exhibit A attached hereto. Upon
execution of such confirmation, the portion of any Hedge Transaction in respect of the notional volumes of the production attributable to the Withdrawal Right Interest shall cease to be a Hedge Transaction for purposes of the Hedging Facility
Agreement and shall be deemed to be a Secured Swap Agreement under the Credit Agreements. 
 Section 3.3 Insurance
Proceeds. The parties hereto acknowledge that in some instances, the Master General Partner maintains insurance on behalf of the Participating Partnerships and that, in such instances, the First Lien Administrative Agent (and upon the Discharge
of First Lien Obligations, the Second Lien Administrative Agent) shall be named as “loss payee” with respect to Property loss insurance pursuant to the terms of the Loan Documents and the Hedging Facility Agreement. In the event that
either Administrative Agent receives insurance proceeds as a result of the loss of any Property owned by a Participating Partnership, such Administrative Agent shall turn over such proceeds to the Collateral Agent for the benefit of the Hedging
Facility Secured Parties. In the event that the Collateral Agent receives insurance proceeds as a result of the loss of any Property owned by Master General Partner, the Collateral Agent shall turn over such proceeds to the First Lien Administrative
Agent (and upon the Discharge of First Lien Obligations, the Second Lien Administrative Agent) for application in accordance with the terms of the Parent Intercreditor Agreement.

any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments are several and no Lender shall be responsible for any other Lender’s failure to make
Loans as required. 
 (b) Types of Loans. Subject to Section 3.03, each Borrowing shall be comprised entirely
of ABR Loans or Eurodollar Loans as the Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that

 (c) Minimum Amount; Limitation on Number of Borrowings. At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral
multiple of $100,000 and not less than $1,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $1,000,000. Borrowings of more than one Type

Lender on a schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender; provided that the failure to make any such notation or to attach a schedule shall not affect any Lender’s or the

outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing (and any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective)

funds by 1:00 p.m., New York, New York time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly
crediting the amounts so received, in like funds, to an account designated by the Borrower in the applicable Borrowing Request. 

(b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have received notice from a Lender prior to the
proposed date of the Borrowing (or, in the case of any ABR Borrowing, prior to 12:00 p.m., New York, New York time, on the date of such Borrowing) that such Lender will not make available to the Administrative Agent such Lender’s share of the
Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding
amount. In such event, if a Lender has not in fact made its share of the Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such
corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater
of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such

under Section 5.02.

 ARTICLE IV 
 PAYMENTS; PRO RATA TREATMENT; SHARING OF SET-OFFS 
 Section 4.01
Payments Generally; Pro Rata Treatment; Sharing of Set-offs. 
 (a) Payments by the Borrower. The Borrower shall
make each payment required to be made by it hereunder (whether of principal, interest, fees, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00 noon, New York, New
York time, on the date when due, in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall not be refundable under any circumstances. Any amounts received after
such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent
at its offices specified in Section 12.01, except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons entitled
thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a
Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in
dollars. 
 (b) Application of Insufficient Payments. If at any time prior the Termination Date, insufficient funds are
received by and available to the Administrative Agent to pay fully all amounts of principal, interest, fees and other amounts then due hereunder, such funds shall be applied: first, ratably to reimbursement of expenses and indemnities
provided for in this Agreement and the Security Instruments; second, to accrued interest on the Loans; third, to fees; and fourth, pro rata to outstanding principal of the Loans; in each case, ratably among the parties entitled
thereto in accordance with the amounts then due to such parties. 
 (c) Sharing of Payments by Lenders. If any Lender
shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its
Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so
that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided that (i) if any such participations are
purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this
Section 4.01(c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale
of a participation in any of its Loans to any assignee or participant, other than to a Loan Party or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply). The Borrower consents to the foregoing and agrees,
to the extent it may effectively do so 

  
 -35-

 
under applicable law and under this Agreement, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. 
 Section 4.02 Presumption of Payment by the Borrower. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative
Agent for the account of the Lenders that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute
to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with
interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank compensation. 
 Section 4.03 Certain Deductions
by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant hereto then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. After acceleration or maturity of the Loans, all
principal will be paid ratably as provided in Section 10.02(c). 
 Section 4.04 Disposition of Proceeds. The
Security Instruments contain an assignment by the Borrower and/or the other Loan Parties unto and in favor of the Administrative Agent for the benefit of the Lenders of all of the Borrower’s or each other Loan Party’s interest in and to
production and all proceeds attributable thereto which may be produced from or allocated to the Mortgaged Property. The Security Instruments further provide in general for the application of such proceeds to the satisfaction of the Indebtedness and
other obligations described therein and secured thereby. Notwithstanding the assignment contained in such Security Instruments, until the occurrence of an Event of Default, the Administrative Agent and the Lenders agree that they will neither notify
the purchaser or purchasers of such production nor take any other action to cause such proceeds to be remitted to the Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower or any other
applicable Loan Party and the Lenders hereby authorize the Administrative Agent to take such actions as may be necessary to cause such proceeds to be paid to the Borrower and/or such Loan Parties.

 ARTICLE V 
 INCREASED COSTS; BREAK FUNDING PAYMENTS; TAXES 
 Section 5.01
Increased Costs. 
 (a) Eurodollar Changes in Law. If any Change in Law shall: 

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with
or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or 
 (ii) impose on any Lender or the London interbank market any other condition (other than Excluded Taxes) affecting this Agreement or Eurodollar Loans made by such Lender; 

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise), in each case by an amount deemed by such Lender to be material, then the Borrower will pay to
such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. 
 (b) Capital Requirements. If any Lender determines that any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such
Lender’s capital or on the capital of such Lender’s holding company, if any, in each case by an amount deemed by such Lender to be material, as a consequence of this Agreement or the Loans made by such Lender, to a level below that which
such Lender or such Lender’s holding company would have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy and
liquidity), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered. 

(c) Certificates. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding
company, as the case may be, as specified in Section 5.01(a) or (b) and reasonably detailed calculations therefor shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such
Lender the amount shown as due on any such certificate within 30 days after receipt thereof. 
 (d) Effect of Failure or
Delay in Requesting Compensation. Failure or delay on the part of any Lender to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s right to demand such compensation; provided
that the Borrower shall not be required to compensate a Lender pursuant to this Section 5.01 for any increased costs or reductions incurred more than 180 days prior to the date that such Lender notifies the Borrower of the Change in Law
giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the
180-day period referred to above shall be extended to include the period of retroactive effect thereof. 

  
 -37-

 Section 5.02 Break Funding Payments. In the event of (a) the payment of any
principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the
Interest Period applicable thereto, or (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any Eurodollar Loan other than on the
last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 5.05, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such
event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal
amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a
failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender
would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. 
 A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 5.02 shall be delivered to the Borrower and shall be conclusive
absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 30 days after receipt thereof. 
 Section 5.03 Taxes. 
 (a) Payments Free of Taxes. Any
and all payments by or on account of any obligation of the Borrower or any Guarantor under any Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower or any
Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (a) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional
sums payable under this Section 5.03(a)), the Administrative Agent or Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (b) the Borrower or such Guarantor shall
make such deductions and (c) the Borrower or such Guarantor shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 
 (b) Payment of Other Taxes by the Borrower. In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. 

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent and each Lender, within 10 days after
written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such 

  
 -38-

 
Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section 5.03) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. A certificate of the Administrative Agent or a Lender as to the amount of such payment or liability under this Section 5.03) shall be delivered to the Borrower and shall be
conclusive absent manifest error. 
 (d) Evidence of Payments. As soon as practicable after any payment of Indemnified
Taxes or Other Taxes by the Borrower or a Guarantor to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a
copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 
 (e) Status of Lenders. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower
and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit
such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or
reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding
anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 5.03(e)(ii)(A), (ii)(B) and (ii)(D) below) shall
not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such
Lender. 
 (ii) Without limiting the generality of the foregoing, 

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

  
 -39-

 (1) in the case of a Foreign Lender claiming the benefits of an income tax
treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the
“interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the
“business profits” or “other income” article of such tax treaty; 
 (2) executed originals
of IRS Form W-8ECI; 
 (3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio
interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit J-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a
“10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance
Certificate”) and (y) executed originals of IRS Form W-8BEN; or 
 (4) to the extent a Foreign
Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit J-2 or Exhibit J-3, IRS Form W-9, and/or
other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption,
such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit J-4 on behalf of each such direct and indirect partner; 

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the
Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the
Borrower or the Administrative Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary
documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and 

  
 -40-

 (D) if a payment made to a Lender under any Loan Document would be subject
to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall
deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as
prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their
obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D),
“FATCA” shall include any amendments made to FATCA after the date of this Agreement. 
 Each Lender agrees that if any
form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do
so. 
 (f) Indemnification by Lenders. Each Lender shall severally indemnify the Administrative Agent, within 10 days
after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of
the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 12.04(c) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable
to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the
Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative
Agent under this paragraph (f). 
 (g) FATCA. If a payment made to a Lender under this Agreement would be subject
to United States Federal withholding tax imposed by FATCA if such Lender fails to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall
deliver to the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding Agent, such documentation prescribed by applicable law (including as prescribed by
Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that such Lender has
complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. 

  
 -41-

 (h) Tax Refunds. If the Administrative Agent or any Lender determines, in its sole
discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 5.03, it shall pay over
such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 5.03 with respect to the Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided that the Borrower, upon the request of the
Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the
Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This Section 5.03 shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any
other information relating to its taxes which it deems confidential) to the Borrower or any other Person. 
 (i)
Survival. The agreements in this Section 5.03 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder. 

Section 5.04 Designation of Different Lending Office. If any Lender requests compensation under Section 5.01, or if
the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, then such Lender shall use reasonable efforts to designate a different lending
office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (a) would eliminate or
reduce amounts payable pursuant to Section 5.01 or Section 5.03, as the case may be, in the future and (b) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to
such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 
 Section 5.05 Replacement of Lenders. If (a) any Lender requests compensation under Section 5.01, (b) the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 5.03, or (c) any Lender has not approved a proposed waiver or amendment but which has been approved by Lenders holding 50% or more of the then outstanding
Loans, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in
Section 12.04(b)), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that
(i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of
its Loans, accrued interest thereon, accrued fees and all other amounts payable to it 

  
 -42-

 
hereunder and under the other Loan Documents, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts), and
(iii) in the case of any such assignment resulting from a claim for compensation under Section 5.01 or payments required to be made pursuant to Section 5.03, such assignment will result in a reduction in such
compensation or payments. 
 Section 5.06 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 Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall promptly notify
the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as such Lender may again make and maintain such Eurodollar
Loans and (b) all Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender then
outstanding shall be automatically converted into ABR 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) ABR Loans, all payments of principal which would otherwise be
applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans; provided that the Borrower shall not be required to make any payments pursuant to Section 5.02 as a result of the conversion of any Affected
Loans under this Section 5.06.

 ARTICLE VII 

REPRESENTATIONS AND WARRANTIES 
 Subject to Section 6.02(a)(ii), the Borrower represents and warrants to the Lenders that: 
 Section 7.01 Organization; Powers. Each of the Borrower and the Restricted Subsidiaries is duly organized, validly existing and in good standing under the laws of the jurisdiction of its
organization, has all requisite power and authority, and has all material governmental licenses, authorizations, consents and approvals necessary, to own its assets and to carry on its business as now conducted, and is qualified to do business in,
and is in good standing in, every jurisdiction where such qualification is required,

 Section 7.02 Authority; Enforceability. The Transactions are within each Loan Party’s corporate powers and have been duly authorized by all necessary corporate and, if required, member action.
Each Loan Document has been duly executed and delivered by it and constitutes a legal, valid and binding obligation of such Loan Party, as applicable, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law. 

Section 7.03 Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing
with, or any other action by, any Governmental Authority or any other third Person, nor is any such consent, approval, registration, filing or other action necessary for the validity or enforceability of any Loan Document or the consummation of the
transactions contemplated thereby, except such as have been obtained or made and are in full force and effect other than (i) the recording and filing of the Security Instruments as required by this Agreement and (ii) those third party
approvals or consents which, if not made or obtained, would not cause a Default hereunder, could not reasonably be expected to have a Material Adverse Effect or do not have an adverse effect on the enforceability of the Loan Documents,

  
 -47-

 
(b) will not violate any applicable law or regulation or the charter, by-laws or other organizational documents of any Loan Party or any order of any Governmental Authority, (c) will
not violate or result in a default under any indenture, agreement or other instrument binding upon any Loan Party or its Properties, or give rise to a right thereunder to require any payment to be made by any Loan Party and (d) will not result
in the creation or imposition of any Lien on any Property of any Loan Party (other than the Liens created by the Loan Documents or permitted under Section 9.03). 
 Section 7.04 Financial Condition; No Material Adverse Change. (a) The Borrower has heretofore furnished in accordance with Section 8.01 to the Lenders (i) the consolidated balance
sheets of the Borrower as of December 31, 2011 and 2010, and the related consolidated statements of operations, comprehensive income, partners’ capital, and cash flows for each of the three years in the period ended December 31, 2011,
certified by its independent public accountants; and (ii) the consolidated balance sheet of the Borrower as of September 30, 2012, and the related consolidated statements of operations, comprehensive income, partners’ capital, and
cash flows for the three month and nine month periods then ended, certified by its chief financial officer. Such financial statements present fairly, in all material respects, the combined or consolidated, as applicable, financial position and
results of operations and cash flows of the Borrower and its consolidated Subsidiaries, as of such dates and for such periods in accordance with GAAP, subject to year-end audit adjustments and the absence of footnotes in the case of the unaudited
quarterly financial statements. 
 (b) The Borrower has previously delivered to the Lenders the pro forma condensed consolidated
balance sheet of the Borrower and its consolidated Subsidiaries as of September 30, 2012, and the related pro forma condensed consolidated statements of operations for the Borrower for the nine months then ended and for the 12 months ended
December 31, 2011 (collectively, the “Pro Forma Financial Statements”). The Pro Forma Financial Statements (i) give effect to the Transactions and the DTE Acquisition as if they had occurred on such date in the case of the
balance sheet and as of the beginning of the periods presented in the case of the statements of operations, (ii) have been prepared in good faith by the Loan Parties, based on the assumptions stated therein (which assumptions are believed by
the Loan Parties on the Effective Date to be reasonable), (iii) accurately reflect all adjustments required to be made to give effect to the Transactions and the DTE Acquisition, and (iv) are in accordance with Regulation S-X and present
fairly in all material respects the pro forma consolidated financial position and results of operations of the Borrower as of such date and for such periods, assuming that the Transactions and the DTE Acquisition had occurred at such dates.

 (c) Since December 31, 2011, after giving effect to the DTE Acquisition and the adjustments set forth in the pro forma
condensed consolidated balance sheet of the Borrower and its consolidated Subsidiaries as of September 30, 2012 which was previously delivered to the Lenders, (i) there has been no event, development or circumstance that has had or could
reasonably be expected to have a Material Adverse Effect and (ii) the business of the Loan Parties has been conducted only in the ordinary course consistent with past business practices.

any material contingent liabilities, off-balance sheet liabilities or partnerships, liabilities for taxes, unusual forward or long-term 

  
 -48-

 
commitments or unrealized or anticipated losses from any unfavorable commitments, except as referred to or reflected or provided for in the Pro Forma Financial Statements or as disclosed in this
Agreement (including the Schedules hereto). 
 Section 7.05 Litigation. Except as set forth on Schedule 7.05,
there are no actions, suits, investigations or proceedings by or before any arbitrator or Governmental Authority pending against or affecting the Borrower or any Restricted Subsidiary (i) as to which there is a reasonable possibility of an
adverse determination that, if adversely determined, could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect or (ii) that involve any Loan Document, the Transactions and the Acquisition and to the
knowledge of the Borrower no such action, suit, investigation or proceeding is threatened. 
 Section 7.06 Environmental
Matters. Except for such matters as set forth on Schedule 7.06 or that, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect: 

(a) Neither any Property of the Borrower or any Restricted Subsidiary nor the operations conducted thereon violate any order or
requirement of any court or Governmental Authority or any Environmental Laws. 
 (b) Without limitation of clause (a)
above, no Property of the Borrower or any Restricted Subsidiary nor the operations currently conducted thereon or, to the best knowledge of any Loan Party, by any prior owner or operator of such Property or operation, are in violation of or subject
to any existing, pending or threatened action, suit, investigation, inquiry or proceeding by or before any court or Governmental Authority or to any remedial obligations under Environmental Laws. 

(c) All notices, permits, licenses or similar authorizations, if any, required to be obtained or filed in connection with the operation
or use of any and all Property of the Borrower and each Restricted Subsidiary, including without limitation past or present treatment, storage, disposal or release of a Hazardous Material or solid waste into the environment, have been duly obtained
or filed, and the Borrower and each Restricted Subsidiary are in compliance with the terms and conditions of all such notices, permits, licenses and similar authorizations. 
 (d) All Hazardous Materials, solid waste, and oil and gas exploration and production wastes, if any, generated at any and all Property of the Borrower or any Restricted Subsidiary have in the past been
transported, treated and disposed of in accordance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or welfare or the environment, and, to the best knowledge of the Loan Parties, all such
transport carriers and treatment and disposal facilities have been and are operating in compliance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or welfare or the environment, and are not the
subject of any existing, pending or threatened action, investigation or inquiry by any Governmental Authority in connection with any Environmental Laws. 
 (e) The Borrower has taken all steps reasonably necessary to determine and have determined that no Hazardous Materials, solid waste, or oil and gas exploration and production

  
 -49-

 
wastes, have been disposed of or otherwise Released and there has been no threatened Release of any Hazardous Materials on or to any Property of the Borrower or any Restricted Subsidiary except
in compliance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or welfare or the environment. 
 (f) To the extent applicable, all Property of the Borrower and each Restricted Subsidiary currently satisfies all design, operation, and equipment requirements imposed by the OPA or scheduled as of the
Effective Date to be imposed by OPA during the term of this Agreement, and the Borrower does not have any reason to believe that such Property, to the extent subject to OPA, will not be able to maintain compliance with the OPA requirements during
the term of this Agreement. 
 (g) Neither the Borrower nor any Restricted Subsidiary has any known contingent liability in
connection with any Release or threatened Release of any oil, Hazardous Material or solid waste into the environment. 
 Section
7.07 Compliance with the Laws and Agreements; No Defaults. (a) Each of the Borrower and each Restricted Subsidiary (i) is in compliance with all Laws applicable to it or its Property and all agreements and other instruments binding upon
it or its Property, and (ii) possesses all licenses, permits, franchises, exemptions, approvals and other governmental authorizations necessary for the ownership of its Property and the conduct of its business, except in each case where the
failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. 

(b) Neither the Borrower nor any Restricted Subsidiary 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 or would require the Borrower or a Restricted Subsidiary to Redeem or make any offer to Redeem under any indenture, note, credit agreement or
instrument pursuant to which any Material Indebtedness is outstanding or by which the Borrower or any Restricted Subsidiary or any of their Properties is bound. 
 (c) No Event of Default has occurred and is continuing. 
 Section 7.08
Investment Company Act. Neither the Borrower nor any Restricted Subsidiary is an “investment company” or a company “controlled” by an “investment company,” within the meaning of, or subject to regulation under,
the Investment Company Act of 1940, as amended. 
 Section 7.09 No Margin Stock Activities. No Loan Party is engaged
principally, or as one of its or their 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 Regulation T, U or X of the
Board). No part of the proceeds of any Loan will be used for any purpose which violates the provisions of Regulations T, U or X of the Board.

 -50-

 
Restricted Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with GAAP or (b) to the extent that the failure to do so could not reasonably be expected to
result in a Material Adverse Effect. The charges, accruals and reserves on the books of the Borrower and the Restricted Subsidiaries in respect of taxes and other governmental charges are, in the reasonable opinion of the Borrower, adequate. No tax
Lien has been filed and no claim is being asserted with respect to any such tax or other such governmental charge. 
 Section
7.11 ERISA. Except as set forth on Schedule 7.11 and except as could not reasonably be expected to result in a Material Adverse Effect: 
 (a) The Borrower, the Restricted Subsidiaries 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 the Borrower, any Restricted Subsidiary or any ERISA
Affiliate (whether directly or indirectly) of (i) either a civil penalty assessed pursuant to subsections (c), (i) or (l) of section 502 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. 
 (d) No Plan (other than a defined contribution plan) or any

has been or is expected by the Borrower, any Restricted 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 the Borrower, the Restricted Subsidiaries or any ERISA Affiliate is required

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 the Borrower’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) Neither the Borrower, the Restricted Subsidiaries nor any ERISA Affiliate sponsors, maintains, or contributes to an employee welfare benefit plan, as defined in section 3(1) of ERISA, including,
without limitation, any such plan maintained to provide benefits to former employees of such entities, that may not be terminated by the Borrower, a Restricted Subsidiary or any ERISA Affiliate in its sole discretion at any time without any material
liability. 

  
 -51-

 (h) Neither the Borrower, the Restricted Subsidiaries nor any ERISA Affiliate sponsors,
maintains or contributes to, or has at any time in the six-year period preceding the date hereof sponsored, maintained or contributed to, any Multiemployer Plan.

current liability for the Plan. 
 Section 7.12 Disclosure; No Material Misstatements. The Borrower has disclosed to the
Administrative Agent and the Lenders all agreements, instruments and corporate or other restrictions to which it or any of the Restricted Subsidiaries is subject, and all other matters known to it, that in each case, individually or in the
aggregate, could reasonably be expected to result in a Material Adverse Effect. None of the reports, financial statements, certificates or other written information furnished by or on behalf of the Borrower or any of the Restricted Subsidiaries to
the Administrative Agent or any Lender or any of their Affiliates in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder or under any other Loan Document (as modified or supplemented by other
information so furnished, collectively, the “Information”) contained, as of the date delivered, any material misstatement of fact or omitted to state, as of the date delivered, any material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not misleading; and, as of the Effective Date, the Information does not contain any misstatement of fact or omit to state any fact that would make the Information, taken as a
whole and viewed in the light of the circumstances under which the Information was prepared, misleading in any material respect; provided that, with respect to Information consisting of projected financial information or other forward looking
information, the Borrower represents only that such Information was prepared in good faith based upon assumptions believed by the Borrower to be reasonable at the time. 
 Section 7.13 Insurance. The Borrower has, and has caused all the Restricted Subsidiaries to have, (a) all insurance policies sufficient for the compliance by each of them with all material
Laws and all material agreements and (b) insurance coverage in at least amounts and against such risk (including, without limitation, public liability) that are usually insured against by companies similarly situated and engaged in the same or
a similar business for the assets and operations of the Borrower and the Restricted Subsidiaries. All Designated Partnerships maintain all appropriate insurance policies to the extent contemplated or required under the limited partnership agreement
(or similar governing document) of such Designated Partnership. With respect to insurance policies of the Borrower and the Restricted Subsidiaries, the Administrative Agent and the Lenders have been named as additional insureds in respect of such
liability insurance policies and the Administrative Agent has been named as loss payee with respect to Property loss insurance. 

Section 7.14 Restriction on Liens. Neither the Borrower nor any of the Restricted Subsidiaries is a party to any material
agreement or arrangement (other than the First Lien Loan Documents and Capital Leases creating Liens permitted by Section 9.03(c), but then only on the Property subject of such Capital Lease), or subject to any order, judgment, writ or
decree, which either restricts or purports to restrict its ability to grant Liens to the Administrative Agent and the Lenders on or in respect of their Properties to secure the Indebtedness and the Loan Documents. 

  
 -52-

Neither the Borrower nor any Restricted Subsidiary has any Foreign Subsidiaries (other than any Subsidiary that is organized under the laws of Canada or any province or territory thereof). Schedule 7.15 lists all the Designated Partnerships
and the Undesignated Partnerships owned by the Borrower or the Restricted Subsidiaries and their partnership interests in each such Designated Partnership and Undesignated Partnership. Schedule 7.15 identifies each Unrestricted Subsidiary
other than Subsidiaries of Unrestricted Subsidiaries. 
 (b) The Borrower’s and the Guarantors’ Equity Interests in
the Designated Partnerships are free and clear of any and all Liens, claims and encumbrances including any preferential rights to purchase and consents to assignments, other than (i) Liens contemplated by the Security Instruments and
(ii) Excepted Liens described in clause (a) or clause (l) of the definition thereof. 
 (c) The amount and type
of the authorized Equity Interests of each of the Persons listed on Schedule 7.15 are accurately described thereon, and all such Equity Interests that are issued and outstanding have been validly issued and are fully paid and nonassessable
and are owned by and issued to the Person listed as their owner on Schedule 7.15. The Borrower and each Guarantor have good and marketable title to all the Equity Interests of the Subsidiaries issued to it, free and clear of all Liens other
than (i) Liens contemplated by the Security Instruments and (ii) Excepted Liens described in clause (a) or (l) of the definition thereof, and all such Equity Interests have been duly and validly issued and are fully paid and
nonassessable (except to the extent general partnership interests are assessable under applicable law). 
 Section 7.16
Location of Business and Offices. The Borrower’s jurisdiction of organization is Delaware; the name of the Borrower as listed in the public records of Delaware is Atlas Resource Partners, L.P.; and the organizational identification
number of the Borrower in Delaware is 5051546 (or, in each case, as set forth in a notice delivered to the Administrative Agent pursuant to Section 8.01(j) in accordance with Section 12.01). The Borrower’s principal
place of business and chief executive offices are located at the address specified in Section 12.01 (or as set forth in a notice delivered pursuant to Section 8.01(j) and Section 12.01(c)). Each other Loan
Party’s jurisdiction of organization, name as listed in the public records of its jurisdiction of organization, organizational identification number in its jurisdiction of organization, and the location of its principal place of business and
chief executive office is stated on Schedule 7.15 (or as set forth in a notice delivered pursuant to Section 8.01(j)). 
 Section 7.17 Properties; Titles, etc. (a) Subject to Immaterial Title Deficiencies, each Loan Party specified as the owner had, as of the date evaluated in the most recently delivered Reserve
Report, direct, good and defensible title as owner of a fee or leasehold interest to the Oil and Gas Properties (other than Designated Partnership Properties) evaluated in such Reserve Report free and clear of Liens except Excepted Liens and Liens
securing the Indebtedness. Each Loan Party has good title to all personal Properties owned by it free and clear of all Liens except Liens permitted by Section 9.03. After giving full effect to the Excepted Liens, each Loan Party
specified as the owner of Hydrocarbon Interests in the most recently delivered Reserve Report 

  
 -53-

 
owned, as of the date evaluated in such Reserve Report, the net interests in production attributable to the Hydrocarbon Interests reflected in such Reserve Report (other than those attributable
to Designated Partnership Properties), and the ownership (whether in fee or by leasehold) of such Properties shall not in any material respect obligate such Loan Party to bear the costs and expenses relating to the maintenance, development and
operations of each such Property in an amount in excess of the working interest of each Property set forth in such Reserve Report that is not offset by a corresponding proportionate increase in such Loan Party’s net revenue interest in such
Property other than as reflected in such Reserve Report; provided that to the extent a Loan Party is a general partner of a Designated Partnership, it is liable for all of the costs and expenses attributable to such Designated
Partnership’s interest but is only entitled to its percentage interest in such Designated Partnership’s net revenues. All information contained in the most recently delivered Reserve Report is true and correct in all material respects as
of the date to which such Reserve Report relates. 
 (b) Subject to Immaterial Title Deficiencies, a Loan Party or a Designated
Partnership had, as of the date evaluated in the most recently delivered Reserve Report, good and defensible title as owner of a fee or leasehold interest to the Designated Partnership Properties evaluated in such Reserve Report, free and clear of
all Liens except Liens described in clause (E) of the definition of “Designated Partnership”. After giving full effect to the Excepted Liens, a Loan Party or a Designated Partnership owned, as of the date evaluated in such Reserve
Report, the net interests in production attributable to the Hydrocarbon Interests relating to Designated Partnership Properties reflected in such Reserve Report, and the ownership (in fee or in leasehold) of such Properties shall not in any material
respect obligate such owner to bear the costs and expenses relating to the maintenance, development and operations of each such Property in an amount in excess of the working interest of each Property set forth in such Reserve Report that is not
offset by a corresponding proportionate increase in such owner’s net revenue interest in such Property other than as reflected in such Reserve Report; provided that to the extent a Loan Party is a general partner of a Designated
Partnership, it is liable for all of the costs and expenses attributable to such Designated Partnership’s interest but is only entitled to its percentage interest in such Designated Partnership’s net revenues. 

(c) All material leases and agreements necessary for the conduct of the business of the Borrower and the Restricted Subsidiaries 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 or leases, except as in each case
could not reasonably be expected to result in a Material Adverse Effect. 
 (d) The rights and Properties presently owned,
leased or licensed by the Borrower and the Restricted Subsidiaries including, without limitation, all easements and rights of way, include all rights and Properties necessary to permit the Borrower and the Restricted Subsidiaries to conduct their
business in all material respects in the same manner as its business has been conducted prior to the date hereof. 
 (e) All of
the Properties of the Borrower and the Restricted Subsidiaries which are reasonably necessary for the material operation of their businesses are in good working condition and are maintained in accordance with prudent business standards. 

  
 -54-

 (f) The Borrower and each Restricted Subsidiary owns, or is licensed to use, all trademarks,
tradenames, copyrights, patents and other intellectual Property material to its business, and the use thereof by the Borrower and such Restricted Subsidiary does not infringe upon the rights of any other Person, except for any such infringements
that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. The Borrower and the Restricted Subsidiaries either own or have valid licenses or other rights to use all databases, geological data,
geophysical data, engineering data, seismic data, maps, interpretations and other technical information used in their businesses as presently conducted, subject to the limitations contained in the agreements governing the use of the same, which
limitations are customary for companies engaged in the business of the exploration and production of Hydrocarbons, with such exceptions as could not reasonably be expected to have a Material Adverse Effect. 

Section 7.18 Maintenance of Properties. Except for such acts or failures to act as could not be reasonably expected to have a
Material Adverse Effect, the Oil and Gas Properties (and Properties unitized therewith) of the Loan Parties and the Designated Partnerships have been maintained, operated and developed in a good and workmanlike manner and in conformity with all Laws
and in conformity with the provisions of all leases, subleases or other contracts comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of such Oil and Gas Properties. Specifically in connection with the
foregoing, except for those as could not be reasonably expected to have a Material Adverse Effect, (a) no Oil and Gas Property owned (whether in fee or by leasehold) by any Loan Party or any Designated Partnership is subject to having allowable
production reduced below the full and regular allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) and (b) none of the wells comprising a part of the Oil and
Gas Properties owned (whether in fee or by leasehold) by any Loan Party or any Designated Partnership (or Properties unitized therewith) is deviated from the vertical more than the maximum permitted by Law, and such wells are, in fact, bottomed
under and are producing from, and the well bores are wholly within, such Oil and Gas Properties (or in the case of wells located on Properties unitized therewith, such unitized Properties). All pipelines, wells, gas processing plants, platforms and
other material improvements, fixtures and equipment owned in whole or in part by any Loan Party or any Designated Partnership that are necessary to conduct normal operations are being maintained in a state adequate to conduct normal operations, and
with respect to such of the foregoing which are operated by any Loan Party or any Designated Partnership, in a manner consistent with such Loan Party’s or Designated Partnership’s past practices (other than those the failure of which to
maintain in accordance with this Section 7.18 could not reasonably be expect to have a Material Adverse Effect). 

Section 7.19 Gas Imbalances. As of the date hereof, except as set forth on Schedule 7.19, on a net basis there are no gas
imbalances or other prepayments made to the Borrower, any Restricted Subsidiary or any Designated Partnership with respect to the Oil and Gas Properties evaluated in the Reserve Report that would require the Borrower, any Restricted Subsidiary or
any Designated Partnership to deliver and transfer ownership of at some future time volumes of Hydrocarbons produced from such Oil and Gas Properties having a value (based on current prices) of more than $5,000,000 without receiving full payment
therefor at the time of delivery of those Hydrocarbons. 

  
 -55-

 Section 7.20 Marketing of Production. Except for contracts listed on Schedule
7.20, and thereafter disclosed in writing by the Borrower to the Administrative Agent, in each case as included in the most recently delivered Reserve Report (with respect to all of which contracts the Borrower represents that it or the
Restricted Subsidiaries are receiving a price for all production sold thereunder which is computed substantially in accordance with the terms of the relevant contract and are not having deliveries curtailed substantially below the subject
Property’s delivery capacity except as disclosed in Schedule 7.20 or the most recently delivered Reserve Report), no agreements exist which are not cancelable by the Borrower or a Restricted Subsidiary on 60 days’ notice or less
without penalty to the Borrower or a Restricted Subsidiary or detriment for the sale of production from the Borrower’s or the Restricted Subsidiaries’ Hydrocarbons (including, without limitation, calls on or other rights to purchase
production, whether or not the same are currently being exercised) that (a) pertain to the sale of production at a fixed price and (b) have a maturity or expiry date of longer than six months from the date hereof (in the case of
Schedule 7.20) or the most recently delivered Reserve Report (in the case of each other such agreement). 
 Section 7.21
Swap Agreements. Each report required to be delivered by the Borrower pursuant to Section 8.01(d), sets forth, a true and complete list of all Swap Agreements of the Borrower, each Restricted Subsidiary and each Designated
Partnership, including, all Swap Agreements of a Participating Partnership entered into pursuant to the Designated Partnership Hedge Facility, the type, term, effective date, termination date and notional amounts or volumes and the net mark to
market value thereof, all credit support agreements relating thereto (including any margin required or supplied) and the counterparty to each such agreement. All reports and other information relating to the Designated Partnership Hedge Facility

Section 8.12 Title Information. (a) The Borrower shall, at all times during the term of this Agreement, make available for review

reasonably requested by the Administrative Agent covering the Oil and Gas Properties evaluated in the most recently delivered Reserve Report. 
 (b) In connection with the delivery of each Reserve Report required by Section 8.11(a), the Borrower shall take all commercially reasonable efforts to ensure that the Administrative Agent
shall have received or have been provided reasonable access to, on or prior to the date such Reserve Report is required to be delivered pursuant to Section 8.11(a), title information (reasonably satisfactory to the Administrative Agent)
as the Administrative Agent may reasonably require with respect to any Oil and Gas Properties evaluated in such Reserve Report so that the Administrative Agent shall have received, together with title information previously reviewed by the
Administrative Agent, the Minimum Title Information. 

  
 -65-

 (c) If the Borrower has provided or made reasonably available title information for
Properties under Section 8.12(a) or Section 8.12(b), the Borrower shall, within 90 days of notice from the Administrative Agent that the Administrative Agent has reasonably determined that title defects, exceptions or
omissions (other than Excepted Liens (subject to the provisos at the end of such definition) and Immaterial Title Deficiencies) exist with respect to such Properties, either (i) cure any such title defects, exceptions or omissions (including
defects or exceptions as to priority) which are not permitted by Section 9.03, (ii) substitute Mortgaged Properties with no title defects, exceptions or omissions except for Immaterial Title Deficiencies and Excepted Liens (subject

evaluated in the most recently delivered Reserve Report (and other Oil and Gas Properties submitted as Mortgaged Properties under the foregoing clause (ii)) free from such title defects, exceptions or omissions (other than Excepted Liens
(subject to the provisos at the end of such definition) and Immaterial Title Deficiencies). 
 (d) If the Borrower is unable to
take such corrective action as set forth in clause (c) above with respect to any title defect, exception or omission (other than Excepted Liens (subject to the provisos at the end of such definition) and Immaterial Title Deficiencies)
reasonably identified by the Administrative Agent or the Lenders within the 90-day period or the Borrower does not timely provide or make reasonably available the Minimum Title Information, such failure shall not be a Default, but instead the First
Lien Agent and/or the Super Majority Lenders under the First Lien Credit Agreement shall have the right to exercise the remedies provided in the First Lien Credit Agreement in respect thereof. Notwithstanding anything to the contrary contained
herein, the failure of any Designated Partnership to hold record title to any Designated Partnership Property shall not be deemed to be a title defect, exception or omission with respect to such Designated Partnership Property for the purposes of
this Section 8.12 so long as (i) such Designated Partnership holds beneficial title to such Designated Partnership Property and (ii) a Loan Party holds record title to such Designated Partnership Property. 

Section 8.13 Additional Collateral; Additional Guarantors. (a) In connection with each redetermination of the Borrowing Base,
the Borrower shall review the Reserve Report prepared in connection with such redetermination pursuant to Section 8.11 and the Oil and Gas Properties subject to a Mortgage as of the date of such Reserve Report. If the aggregate value of
the Oil and Gas Properties subject to a Mortgage is less than the Required Mortgage Value, then the Borrower shall, and shall cause the Restricted Subsidiaries to, grant within 30 days of the delivery of the certificate referred to in
Section 8.11(c) to the Administrative Agent as security for the Indebtedness a second-priority Lien (provided that Excepted Liens of the type described in clauses (a) to (d), (f) and (l) of the definition thereof
may exist, but subject to the provisos at the end of such definition) on additional Oil and Gas Properties to the extent necessary to cause the aggregate value of the Oil and Gas Properties subject to a Mortgage to equal or exceed the Required
Mortgage Value. All such Liens will be created and perfected by and in accordance with the provisions of Mortgages or other Security Instruments, all in form and substance reasonably satisfactory to the Administrative Agent. Any Restricted
Subsidiary that creates a Lien on its Oil and Gas Properties shall become a Guarantor in accordance with Section 8.13(b). 

  
 -66-

 (b) The Borrower shall promptly cause each Material Subsidiary formed or acquired after the
Effective Date to guarantee the Indebtedness pursuant to the Guaranty Agreement. In connection with any such guaranty, the Borrower shall (i) cause such Material Subsidiary to (A) execute and deliver a Joinder Agreement pursuant to which
such Material Subsidiary becomes a party to the Guaranty Agreement and becomes a Guarantor, and (B) execute and deliver a Joinder Agreement pursuant to which such Material Subsidiary becomes a party to the Security Agreement and grants a

whether by acceleration or otherwise, shall be applied: first, to reimbursement of expenses and indemnities provided for in this Agreement and the Security Instruments; second, to accrued interest on the Loans; third, to fees;
fourth, pro rata to (i) outstanding principal of the Loans; and fifth, to any other Indebtedness; and any excess shall be paid to the Borrower or as otherwise required by any Law. 

ARTICLE XI 

THE ADMINISTRATIVE AGENT 
 Section 11.01 Appointment and Authorization of Administrative Agent. Each Lender hereby irrevocably (subject to Section 11.10) appoints, designates and authorizes the Administrative
Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto. Each Lender hereby consents to the terms of, and authorizes the Administrative Agent to enter into the form of intercreditor agreement that is substantially in the form
attached hereto as Exhibit L, and each Lender agrees that the terms of such intercreditor agreement shall be binding on such Lender and its successors and assigns, as if it were a party thereto. Notwithstanding any provision to the contrary
contained elsewhere herein or in any other Loan Document, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall the Administrative Agent have or be deemed to have any fiduciary
relationship with any Lender or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent.
Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent, any syndication agent or documentation agent is not intended to
connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative
relationship between independent contracting parties. 
 Section 11.02 Delegation of Duties. The Administrative Agent may
execute any of its duties under this Agreement or any other Loan Document by or through agents, sub-agents, employees or attorneys in fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining
to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agent or attorney in fact that it selects in the absence of gross negligence or willful misconduct.

 Section 11.03 Default; Collateral. (a) Upon the occurrence and continuance of a
Default or Event of Default, the Lenders agree to promptly confer in order that the Majority Lenders or the Lenders, as the case may be, may agree upon a course of action for the enforcement of the rights of the Lenders; and the Administrative Agent
shall be entitled to refrain from taking any action (without incurring any liability to any Person for so refraining) unless and until the Administrative Agent shall have received instructions from the Majority Lenders or the Lenders, as the case
may be. All rights of action under the Loan Documents and all right to the Mortgaged Properties, if any, hereunder may be enforced by the Administrative Agent and any suit or proceeding instituted by the Administrative Agent in furtherance of such
enforcement shall be brought in its name as the Administrative Agent without the necessity of joining as plaintiffs or defendants any other Lender, and the recovery of any judgment shall be for the benefit of the Lenders subject to the expenses of
the Administrative Agent. In actions with respect to any Property of the Borrower or any Restricted Subsidiary, the Administrative Agent is acting for the ratable benefit of each Lender. Any and all agreements to subordinate (whether made heretofore
or hereafter) other indebtedness or obligations of Borrower to the Indebtedness shall be construed as being for the ratable benefit of each Lender. 
 (b) Each Lender authorizes and directs the Administrative Agent to enter into the Security Instruments on behalf of and for the benefit of the Lenders (or if previously entered into, hereby ratifies the
Administrative Agent’s (or any predecessor administrative agent’s) previously entering into such agreements and Security Instruments). 
 (c) Except to the extent unanimity (or other percentage set forth in Section 12.02) is required hereunder, each Lender agrees that any action taken by the Majority Lenders in accordance with
the provisions of the Loan Documents, and the exercise by the Majority Lenders of the power set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders.

 (d) The Administrative Agent is hereby authorized on behalf of the Lenders, without the necessity of any notice to or further
consent from any Lender, from time to time to take any action with respect to any Mortgaged Property or Security Instruments which may be necessary to perfect and maintain perfected Liens upon the Mortgaged Properties granted pursuant to the
Security Instruments. 
 (e) The Administrative Agent shall not have any obligation whatsoever to any Lender or to any other
Person to assure that the Mortgaged Property exists or is owned (whether in fee or by leasehold) by the Person purporting to own it or is cared for, protected, or insured or has been encumbered or that the Liens granted to the Administrative Agent
(or any predecessor administrative agent) herein or pursuant thereto have been properly or sufficiently or lawfully created, perfected, protected, or enforced, or are entitled to any particular priority, or to exercise at all or in any particular
manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights granted or available to the Administrative Agent in this Section 11.03 or in any of the Security Instruments; IT BEING UNDERSTOOD AND
AGREED THAT IN RESPECT OF THE MORTGAGED PROPERTY, OR ANY ACT, OMISSION, OR 

  
 -89-

 
EVENT RELATED THERETO, THE ADMINISTRATIVE AGENT MAY ACT IN ANY MANNER IT MAY DEEM APPROPRIATE, IN ITS SOLE DISCRETION, GIVEN THE ADMINISTRATIVE AGENT’S OWN INTEREST IN THE MORTGAGED PROPERTY
AS ONE OF THE LENDERS AND THAT THE ADMINISTRATIVE AGENT SHALL HAVE NO DUTY OR LIABILITY WHATSOEVER TO ANY LENDER, OTHER THAN TO ACT WITHOUT GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. 

(f) The Lenders hereby irrevocably authorize the Administrative Agent, at its option and in its discretion, to release any Lien granted
to or held by the Administrative Agent upon any Mortgaged Property: (A) constituting property in which neither Borrower nor any Restricted Subsidiary owned an interest at the time the Lien was granted or at any time thereafter;
(B) constituting property leased to the Borrower or a Restricted Subsidiary under a lease which has expired or been terminated in a transaction permitted under the Loan Documents or is about to expire and which has not been, and is not intended
by the Borrower or such Restricted Subsidiary to be, renewed; or (C) consisting of an instrument or other possessory collateral evidencing Debt or other obligations pledged to the Administrative Agent (for the benefit of the Lenders), if the
Debt or obligations evidenced thereby has been paid in full or otherwise superseded. In addition, the Lenders irrevocably authorize the Administrative Agent to release Liens upon Mortgaged Property as contemplated herein and in the other Loan
Documents, or if approved, authorized, or ratified in writing by the requisite Lenders. Upon request by the Administrative Agent at any time, the Lenders will confirm in writing the Administrative Agent’s authority to release particular types
or items of Mortgaged Property pursuant to this Section 11.03. 
 (g) In furtherance of the authorizations set forth
in this Section 11.03, each Lender hereby irrevocably appoints the Administrative Agent as its attorney-in-fact, with full power of substitution, for and on behalf of and in the name of each such Lender (i) to enter into Security
Instruments (including, without limitation, any appointments of substitute trustees under any Security Instruments), (ii) to take action with respect to the Mortgaged Property and Security Instruments to perfect, maintain, and preserve the
Lenders’ Liens, and (iii) to execute instruments of release or to take other action necessary to release Liens upon any Mortgaged Property to the extent authorized herein or in the other Loan Documents. This power of attorney shall be
liberally, not restrictively, construed so as to give the greatest latitude to the Administrative Agent’s power, as attorney, relative to the Mortgaged Property matters described in this Section 11.03. The powers and authorities
herein conferred on the Administrative Agent may be exercised by the Administrative Agent through any Person who, at the time of the execution of a particular instrument, is an officer of the Administrative Agent (or any Person acting on behalf of
the Administrative Agent pursuant to a valid power of attorney). The power of attorney conferred by this Section 11.03(g) to the Administrative Agent is granted for valuable consideration and is coupled with an interest and is
irrevocable so long as the Indebtedness, or any part thereof, shall remain unpaid. 
 Section 11.04 Liability of
Administrative Agent. NO RELATED PARTY OF THE ADMINISTRATIVE AGENT SHALL (A) BE LIABLE FOR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY ANY OF THEM UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY (EXCEPT FOR ITS OWN GROSS NEGLIGENCE OR 

  
 -90-

 
WILLFUL MISCONDUCT IN CONNECTION WITH ITS DUTIES EXPRESSLY SET FORTH HEREIN), or (b) be responsible in any manner to any Lender or participant for any recital, statement, representation or
warranty made by the Borrower or any Restricted Subsidiary or any officer thereof, contained herein or in any other Loan Document, or in any certificate, report, statement or other document referred to or provided for in, or received by the
Administrative Agent under or in connection with, this Agreement or any other Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document, or for the creation, perfection or
priority of any Liens purported to be created by any of the Loan Documents, or the validity, genuineness, enforceability, existence, value or sufficiency of any collateral security, or to make any inquiry respecting the performance by the Borrower
of its obligations hereunder or under any other Loan Document, or for any failure of the Borrower or any Restricted Subsidiary or any other party to any Loan Document to perform its obligations hereunder or thereunder. No Related Party of the
Administrative Agent shall be under any obligation to any Lender or Participant to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to
inspect the properties, books or records of the Borrower or any Restricted Subsidiary or any Affiliate thereof. 
 Section 11.05
Reliance by Administrative Agent. (a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate,
affidavit, letter, telegram, facsimile, electronic mail, or telephone message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon
advice and statements of legal counsel (including counsel to the Borrower or any Restricted Subsidiary), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or
refusing to take any action under any Loan Document unless it shall first receive such advice or concurrence of the Majority Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this
Agreement or any other Loan Document in accordance with a request or consent of the Majority Lenders or all the Lenders, if required hereunder, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and Participants. Where this Agreement expressly permits or prohibits an action unless the Majority Lenders or Super Majority Lenders otherwise determine, the Administrative Agent shall, and in all other instances, the Administrative Agent
may, but shall not be required to, initiate any solicitation for the consent or a vote of the requisite Lenders. 
 (b) For
purposes of determining compliance with the conditions specified in Section 6.01, each Lender that has funded its Applicable Percentage of the Loan on the Effective Date (or, if there is no Loan made on such date, each Lender other than
the Lenders who gave written objection to the Administrative Agent prior to such date) shall be deemed to have consented to, approved or accepted, or to be satisfied with, each document or other matter either sent by the Administrative Agent to such
Lender (or otherwise made available for such Lender on SyndTrak Online, DXSyndicateTM or any similar website) for consent, approval, acceptance or satisfaction, or required hereunder to be consented to or approved by or acceptable or
satisfactory to a Lender. 

  
 -91-

 Section 11.06 Notice of Default. The Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the Lenders, unless the
Administrative Agent shall have received written notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” The Administrative Agent
will notify the Lenders of its receipt of any such notice. The Administrative Agent shall take such action with respect to such Default or Event of Default as may be directed by the Majority Lenders in accordance with this Agreement;
provided, however, that unless and until the Administrative Agent has received any such direction, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable or in the best interest of the Lenders. 
 Section 11.07 Credit
Decision; Disclosure of Information by Administrative Agent. Each Lender acknowledges that no Related Party of the Administrative Agent has made any representation or warranty to it, and that no act by the Administrative Agent hereinafter taken,
including any consent to and acceptance of any assignment or review of the affairs of the Borrower or any Restricted Subsidiary or any Affiliate thereof, shall be deemed to constitute any representation or warranty by any Related Party of the
Administrative Agent to any Lender as to any matter, including whether Related Parties of the Administrative Agent have disclosed material information in their possession. Each Lender represents to the Administrative Agent that it has, independently
and without reliance upon any Related Party of the Administrative Agent and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property,
financial and other condition and creditworthiness of the Borrower, any Guarantor and their respective Subsidiaries, and all applicable bank or other regulatory laws relating to the transactions contemplated hereby, and made its own decision to
enter into this Agreement and to extend credit to the Borrower hereunder. Each Lender also represents that it will, independently and without reliance upon any Related Party of the Administrative Agent and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigations as it deems necessary to
inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties. In this regard, each Lender acknowledges that Cadwalader, Wickersham & Taft
LLP is acting in this transaction as counsel to the Administrative Agent. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated
therein. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent herein, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit
or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come into the possession of any Related Party
of the Administrative Agent.

 Section 11.08 Indemnification of Agents. WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED
HEREBY ARE CONSUMMATED, THE LENDERS SHALL INDEMNIFY UPON DEMAND EACH RELATED PARTY OF THE ADMINISTRATIVE AGENT (TO THE EXTENT NOT REIMBURSED BY OR ON BEHALF OF THE BORROWER AND WITHOUT LIMITING THE OBLIGATION OF THE BORROWER TO DO SO), IN ACCORDANCE
WITH THEIR RESPECTIVE APPLICABLE PERCENTAGES, AND HOLD HARMLESS EACH RELATED PARTY OF THE ADMINISTRATIVE AGENT FROM AND AGAINST ANY AND ALL INDEMNIFIED LIABILITIES INCURRED BY IT (INCLUDING SUCH RELATED PARTY OF THE ADMINISTRATIVE AGENT’S OWN
NEGLIGENCE); PROVIDED, HOWEVER, THAT NO LENDER SHALL BE LIABLE FOR THE PAYMENT TO ANY RELATED PARTY OF THE ADMINISTRATIVE AGENT OF ANY PORTION OF SUCH INDEMNIFIED LIABILITIES RESULTING FROM SUCH PERSON’S GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT; provided, however, that no action taken in accordance with the directions of the Majority Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section 11.08.
Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other
Loan Document, or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the Borrower. The undertaking in this Section 11.08 shall survive
termination of the Commitments, the payment of all Indebtedness hereunder and the resignation or replacement of the Administrative Agent. 
 Section 11.09 Administrative Agent in its Individual Capacity. Wells Fargo and its Affiliates may make loans to, accept deposits from, acquire equity interests in and generally engage in any kind
of banking, trust, financial advisory, underwriting or other business with the Borrower and its Affiliates as though Wells Fargo were not the Administrative Agent hereunder and without notice to or consent of the Lenders. The Lenders acknowledge
that, pursuant to such activities, Wells Fargo or its Affiliates may receive information regarding the Borrower or its Affiliates (including information that may be subject to confidentiality obligations in favor of the Borrower or such Affiliate)
and acknowledge that the Administrative Agent shall be under no obligation to provide such information to them. With respect to its Loans, Wells Fargo shall have the same rights and powers under this Agreement as any other Lender and may exercise
such rights and powers as though it were not the Administrative Agent, and the terms “Lender” and “Lenders” include Wells Fargo in its individual capacity. 
 Section 11.10 Successor Administrative Agent. The Administrative Agent may resign at any time upon 30 days’ notice to the Lenders with a copy of such notice to the Borrower. If the
Administrative Agent resigns under this Agreement, the Majority Lenders shall appoint from among the Lenders a successor administrative agent for the Lenders which successor administrative agent shall be consented to by the Borrower at all times
other than during the existence of an Event of Default (which consent of the Borrower shall not be unreasonably withheld, delayed or conditioned). If no successor administrative agent is appointed prior to the effective date of the resignation of
the Administrative Agent, the Administrative Agent may 

  
 -93-

 
appoint, after consulting with the Lenders and, so long as no Event of Default has occurred which is continuing, upon written approval of the Borrower (which approval of the Borrower shall not be
unreasonably withheld, delayed or conditioned), a successor administrative agent from among the Lenders. Upon the acceptance of its appointment as successor administrative agent hereunder, such successor administrative agent shall succeed to all the
rights, powers and duties of the retiring Administrative Agent and the term “Administrative Agent” shall mean such successor administrative agent and the retiring Administrative Agent’s appointment, powers and duties as Administrative
Agent shall be terminated. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Article XI and Sections 12.03 and 12.05 shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. If no successor administrative agent has accepted appointment as Administrative Agent by the date which is 30 days following a retiring Administrative
Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as
the Majority Lenders appoint a successor agent as provided for above. 
 Section 11.11 Syndication Agent; Other Agents;
Arrangers. None of the Lenders or other Persons identified on the facing page or signature pages of this Agreement as a “syndication agent,” as a “documentation agent,” any other type of agent (other than the Administrative
Agent), “arranger,” or “bookrunner” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of the
Lenders so identified shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the Lenders so identified in deciding to enter into this Agreement or in
taking or not taking action hereunder. 
 Section 11.12 Administrative Agent May File Proof of Claim. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any Restricted Subsidiary, the Administrative Agent (irrespective of
whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by
intervention in such proceeding or otherwise 
 (a) to file and prove a claim for the whole amount of the principal and interest
owing and unpaid in respect of the Loans and all other Indebtedness that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any
claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under
Section 12.03) allowed in such judicial proceeding; and 
 (b) to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same; 

  
 -94-

 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any
such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the
Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 12.03.

 Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt
on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Indebtedness or the rights of any Lender or to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such
proceeding.

 Section 12.02 Waivers;
Amendments. (a) No failure on the part of the Administrative Agent or any Lender to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege, or any abandonment or discontinuance of steps to
enforce such right, power or privilege, under any of the Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under any of the Loan Documents preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the Administrative Agent and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies
that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by
Section 12.02(b), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a
waiver of any Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Default at the time. 
 (b) Subject to Section 12.04(b)(ii)(E)(4), neither this Agreement nor any provision hereof nor any Security Instrument nor any provision thereof may be waived, amended or modified except
pursuant to an agreement or agreements in writing entered into by the Loan Parties party thereto and the Majority Lenders or by the Borrower and the Administrative Agent with the consent of the Majority Lenders; provided that no such
agreement shall 
 (i) increase the Maximum Credit Amount of any Lender without the written consent of such
Lender, 
 (ii) [Reserved], 

(iii) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable
hereunder, without the written consent of each Lender directly and adversely affected thereby; provided that the consent of an Affiliate Lender for any such reduction shall not be required if such reduction is proportionately applicable to
each Lender (including such Affiliate Lender), 
 (iv) postpone the scheduled date of payment of the principal
amount of any Loan, or any interest thereon, or any fees payable hereunder, or reduce the amount of, 

  
 -96-

 
waive or excuse any such payment, or postpone or extend the Termination Date without the written consent of each Lender directly and adversely affected thereby; provided that the consent
of an Affiliate Lender for any such postponement, reduction, extension or waiver shall not be required if such postponement, reduction, extension or waiver is proportionately applicable to each Lender (including such Affiliate Lender), 

(v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of
payments required thereby, without the written consent of each Lender adversely affected thereby; provided that the consent of an Affiliate Lender for any such change shall not be required if such change is proportionately applicable to each
Lender (including such Affiliate Lender), 
 (vi) release any Guarantor (except as set forth in the Guaranty
Agreement), release all or substantially all of the collateral, or reduce the percentage set forth in the definition of Required Mortgage Value to less than 80%, without the written consent of each Lender (other than any Affiliate Lender), or

 (vii) change any of the provisions of this Section 12.02(b) or the definitions of “Super
Majority Lenders” or “Majority Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any
determination or grant any consent hereunder or any other Loan Documents, without the written consent of each Lender directly and adversely affected thereby; 
 provided further, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder or under any other Loan Document without the prior
written consent of the Administrative Agent. Notwithstanding the foregoing, any supplement to Schedule 7.15 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and,
upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders. 
 Section 12.03 Expenses,
Indemnity; Damage Waiver. (a) The Borrower shall pay (i) all reasonable and documented out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including, without limitation, the reasonable fees, charges and
disbursements of counsel and other outside consultants for the Administrative Agent, the reasonable travel, photocopy, mailing, courier, telephone and other similar expenses, and the cost of environmental audits and surveys and appraisals, in
connection with the syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and administration (both before and after the execution hereof and including advice of counsel to the Administrative
Agent as to the rights and duties of the Administrative Agent and the Lenders with respect thereto) of this Agreement and the other Loan Documents and any amendments, modifications or waivers of or consents related to the provisions hereof or
thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable and documented out-of-pocket costs, expenses, taxes, assessments and other charges incurred by the Administrative Agent or any
Lender in connection with any filing, registration, recording or perfection of any security interest contemplated by this Agreement or any Security Instrument or any other document referred to therein, and (iii) all out-of-pocket expenses

workout, restructuring or similar negotiations in respect of such Loans. 
 (b) THE BORROWER SHALL INDEMNIFY THE ARRANGERS,
THE ADMINISTRATIVE AGENT AND EACH LENDER, AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, DEFEND AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS,
DAMAGES, PENALTIES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE REASONABLE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF
(i) THE EXECUTION OR DELIVERY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY OR THEREBY, THE PERFORMANCE BY THE PARTIES HERETO OR THE PARTIES TO ANY OTHER LOAN DOCUMENT OF THEIR RESPECTIVE
OBLIGATIONS HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY OR BY ANY OTHER LOAN DOCUMENT, (ii) THE FAILURE OF THE BORROWER OR ANY OTHER LOAN PARTY TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING
THIS AGREEMENT, OR WITH ANY LAW, (iii) ANY INACCURACY OF ANY REPRESENTATION OR ANY BREACH OF ANY WARRANTY OR COVENANT OF THE BORROWER OR ANY GUARANTOR SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY INSTRUMENTS, DOCUMENTS OR CERTIFICATIONS

BORROWER OR ANY RESTRICTED SUBSIDIARY OR ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE BORROWER OR ANY OF THE RESTRICTED SUBSIDIARIES, (xii) ANY ENVIRONMENTAL LIABILITY RELATED
IN ANY WAY TO THE BORROWER OR ANY OF THE RESTRICTED SUBSIDIARIES, (xiii) ANY OTHER ENVIRONMENTAL, HEALTH OR SAFETY CONDITION IN CONNECTION WITH THE LOAN DOCUMENTS, OR (xiv) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR
PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, AND SUCH INDEMNITY SHALL EXTEND TO EACH INDEMNITEE NOTWITHSTANDING THE SOLE OR CONCURRENT
NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF
THE INDEMNITEES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNITEES; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS,
DAMAGES, LIABILITIES OR RELATED EXPENSES HAVE RESULTED FROM (1) THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE (AS DETERMINED BY A FINAL, NONAPPEALABLE JUDGMENT OF A COURT OF COMPETENT JURISDICTION), (2) A MATERIAL BREACH OF
THE MATERIAL OBLIGATIONS OF SUCH INDEMNITEE UNDER THE LOAN DOCUMENTS OR (3) ANY PROCEEDING THAT IS SOLELY AMONG INDEMNITEES. 
 (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under Section 12.03(a) or Section 12.03(b), each Lender severally
agrees to pay to the Administrative Agent such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed
expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such. 

(d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any indemnitee, on any
theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument
contemplated hereby or thereby, the Transactions, any Loan or the use of the proceeds thereof. 
 (e) All amounts due under this
Section 12.03 shall be payable promptly after written demand therefor.

 Section 12.04 Successors and Assigns. (a) The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the
prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in
accordance with this Section 12.04. 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 Section 12.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this
Agreement. 
 (b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one
or more assignees (each, an “Assignee”) all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent of:

 (A) the Borrower (such consent not to be unreasonably withheld, conditioned or delayed), provided that
no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund (as defined below) or, if an Event of Default has occurred and is continuing, any other Person; and 

(B) the Administrative Agent (such consent not to be unreasonably withheld, conditioned or delayed), provided that
no consent of the Administrative Agent shall be required for an assignment to a Lender, an Affiliate of a Lender, or an Approved Fund. 
 (ii) Assignments shall be subject to the following additional conditions: 
 (A) except in the case of an assignment to a Lender, an affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the
amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than
$5,000,000 or, if smaller, the entire remaining amount of the assigning Lender’s Maximum Credit Amount, unless each of the Borrower and the Administrative Agent otherwise consent, provided that (1) no such consent of the Borrower
shall be required if an Event of Default has occurred and is continuing and (2) such amounts shall be aggregated in respect of each Lender and its Affiliates or Approved Funds, if any; 

(B) the parties to each assignment (other than assignments to an Affiliate of a Lender or an Approved Fund) shall execute
and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500 unless such fee is waived by the Administrative Agent; 

  
 -100-

 (C) the Assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire; 
 (D) in no event may any Lender assign all or a portion
of its rights and obligations under this Agreement to the Borrower or any of its Affiliates; and 
 (E) any
Lender assign all or a portion of its rights and obligations under this Agreement to an Affiliate of the Borrower, subject to the following limitations: 
 (1) each Affiliate of the Borrower that is an Assignee (each, an “Affiliate Lender”) shall represent and warrant as of the date of any such purchase and assignment, that neither such
Affiliate Lender or any of its Affiliates nor any of their respective directors or officers has any material non-public information with respect to the Borrower or any of its Subsidiaries or securities that has not been disclosed to the assigning
Lender (other than because such assigning Lender does not wish to receive material non-public information with respect to the Borrower and its Subsidiaries or securities) prior to such date to the extent such information could reasonably be expected
to have a material effect upon, or otherwise be material, to a Lender’s decision to assign rights and obligations hereunder to such Affiliate Lender; 
 (2) each Affiliate Lender will not be entitled to receive, and will not receive, information provided solely to the Lenders that are not Affiliate Lenders by the Administrative Agent or any Lender that is
not an Affiliate Lender and will not be permitted to attend or participate in, and will not attend or participate in, meetings or conference calls solely among the Lenders that are not Affiliate Lenders and the Administrative Agent; 

(3) the aggregate percentage of the Aggregate Maximum Credit Amounts or of the outstanding aggregate principal amount of
the Loans (if there are Loans outstanding at such time) held at any one time by all Affiliate Lenders may not exceed 10% of the Aggregate Maximum Credit Amounts or of the principal amount of the Loans, in each case outstanding at such time under
this Agreement; 
 (4) Notwithstanding anything in this Agreement to the contrary, for purposes of determining
whether the Majority Lenders, the Super Majority Lenders or all Lenders have (x) consented (or not consented) to any amendment, modification, waiver, consent or other action with respect to any of the terms of any Loan Document or any departure
by any Loan Party therefrom, or any plan of reorganization pursuant to the U.S. Bankruptcy Code, (y) otherwise acted on any matter 

  
 -101-

 
related to any Loan Document, or (z) directed or required the Administrative Agent or any Lender to undertake any action (or refrain from taking any action) with respect to or under any Loan
Document, all Loans (or Maximum Credit Amounts, as applicable) held by any Affiliate Lender shall be deemed to be not outstanding for all purposes of calculating whether the Majority Lenders, the Super Majority Lenders or all Lenders have taken any
actions; and 
 (5) borrowings of Loans shall not be made to directly or indirectly fund the purchase or
assignment. 
 For the purposes of this Section 12.04, “Approved Fund” means a Person (other than a natural person)
that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or
(c) a Person or an Affiliate of a Person that administers or manages a Lender. 
 (iii) Subject to
acceptance and recording thereof pursuant to paragraph (b)(iv) below, from and after the effective date specified in each Assignment and Assumption the Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by
such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations
under this Agreement (and, in the case of an Assignment and Assumption covering all 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 Section 5.01, Section 5.02, Section 5.03 and Section 12.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this
Section 12.04(b) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.04(c). 

(iv) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its
offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Maximum Credit Amount of, and principal amount of the Loans owing to, each Lender pursuant to the
terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and 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 the Borrower and any Lender, at any reasonable time and from time to time upon
reasonable prior notice. 
 (v) Upon its receipt of a duly completed Assignment and Assumption executed by an
assigning Lender and an Assignee, the Assignee’s completed Administrative Questionnaire (unless the Assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 12.04(b), and any written

  
 -102-

 
consent to such assignment required by Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the
Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 12.04(b). 
 (c) (i) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (each a “Participant”) in all or a
portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain
unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (C) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly
with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement 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 may provide that such Lender will not, without the consent of the Participant, agree to any amendment,
modification or waiver that (1) requires the consent of each Lender directly affected thereby pursuant to Section 12.02(b) and (2) directly affects such Participant. Subject to paragraph (c)(ii) of this Section, the
Borrower agrees that each Participant shall be entitled to the benefits of Section 5.01, Section 5.02, and Section 5.03 to the same extent as if it were a Lender and had acquired its interest by assignment
pursuant to Section 12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08 as though it were a Lender, provided such Participant shall be subject to
Section 4.01 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the
principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to
disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans or its other obligations under any Loan Document) to any Person
except to the extent that such disclosure is necessary to establish that such commitment, loan or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant
Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the
contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register. 

(ii) A Participant shall not be entitled to receive any greater payment under Section 5.01 or
Section 5.03 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. Any Participant that is a Foreign Lender shall not be entitled to the benefits of Section 5.03 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 5.03(e). 

  
 -103-

 (d) Any Lender may at any time pledge or assign a security interest in all or any portion of
its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest;
provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or Assignee for such Lender as a party hereto. 

(e) Notwithstanding the foregoing, any Lender may grant to a Conduit Lender the option to provide to the Borrower all or any part of any
Loan that a Lender would be required to make, and any Conduit Lender may assign any or all of the Loans it may have funded hereunder to its designating Lender, in each case, without the consent of the Borrower or the Administrative Agent and without
regard to the limitations set forth in Section 12.04(b). Each of the Borrower, each Lender and the Administrative Agent hereby confirms that it will not institute against a Conduit Lender or join any other Person in instituting against a
Conduit Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding under any state bankruptcy or similar law, for one year and one day after the payment in full of the latest maturing commercial paper note issued by
such Conduit Lender; provided, however, that each Lender designating any Conduit Lender hereby agrees to indemnify, save and hold harmless each other party hereto for any loss, cost, damage or expense arising out of its inability to
institute such a proceeding against such Conduit Lender during such period of forbearance. 
 Section 12.05 Survival;
Revival; Reinstatement. (a) All covenants, agreements, representations and warranties made by the Borrower herein and by the Loan Parties in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any
other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans regardless of any investigation made by any such other party or
on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and
effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid and so long as the Commitments have not expired or terminated. The provisions of
Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and Article XI shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated
hereby, the repayment of the Loans, the expiration or termination of the Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof. 

(b) To the extent any payment by or on behalf of the Borrower is made to the Administrative Agent or any Lender, and such payment or any
part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent or any Lender in its discretion) to be repaid to a trustee,
receiver or any other party, in connection with any proceeding under any bankruptcy or other laws for the relief of debtors or otherwise, then to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall
be revived and continued in full force and effect as if such payment had not been made. 

  
 -104-

 Section 12.06 Counterparts; Integration; Effectiveness. (a) This Agreement may be
executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. 

(b) This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent
constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. This Agreement
and the other Loan Documents represent the final agreement among the parties hereto and thereto 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. 
 (c) Except as provided in Section 6.01, this Agreement shall become effective when it shall
have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by email (in .pdf or similar format) or telecopy shall be effective as delivery of a
manually executed counterpart of this Agreement. 
 Section 12.07 Severability. Any provision of this Agreement or any
other Loan Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and
enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. 

Section 12.08 Right of Setoff. If an Event of Default under Section 10.01(a) or Section 10.01(b) shall
have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other obligations (of whatsoever kind, including, without limitations obligations under Swap Agreements) at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower or
any Restricted Subsidiary against any of and all the obligations of the Borrower or any Restricted Subsidiary owed to such Lender now or hereafter existing under this Agreement or any other Loan Document, irrespective of whether or not such Lender
shall have made any demand under this Agreement or any other Loan Document and although such obligations may be unmatured. Such Lender shall promptly notify the Borrower after any such set off and application made by such Lender, but the failure to
give such notice will not affect the validity of such set off and application. The rights of each Lender under this Section 12.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender or its
Affiliates may have.

AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 (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, EACH
PARTY 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 PARTY 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 A PARTY FROM OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE HAVING JURISDICTION. 
 (c) EACH PARTY 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 IT AT THE ADDRESS SPECIFIED IN SECTION 12.01 OR SUCH OTHER ADDRESS AS IS SPECIFIED PURSUANT TO SECTION 12.01 (OR ITS ASSIGNMENT AND ASSUMPTION), SUCH SERVICE TO BECOME EFFECTIVE 30 DAYS AFTER SUCH MAILING. NOTHING HEREIN
SHALL AFFECT THE RIGHT OF A PARTY 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 ANOTHER PARTY IN ANY OTHER JURISDICTION. 

(d) EACH PARTY HEREBY (i) IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL
ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN; (ii) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION

 Section 12.10 Headings. Article and Section headings and the Table of Contents used
herein are for convenience of reference only, are not part of this Agreement, and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement. 

Section 12.11 Confidentiality. Each of the Administrative Agent and each Lender agrees to keep confidential all non-public
information provided to it by the Borrower or any of the Restricted Subsidiaries, the Administrative Agent or any Lender pursuant to or in connection with this Agreement that is designated by the provider thereof as confidential; provided
that nothing herein shall prevent the Administrative Agent or any Lender from disclosing any such information (a) to the Administrative Agent, any other Lender or any affiliate thereof (subject, in the case of such disclosure to any affiliate
of the Administrative Agent or a Lender, to the Administrative Agent or such Lender, as applicable, being responsible for compliance by such affiliate with the provisions of this Section 12.11), (b) to its employees, directors,
agents, attorneys, accountants and other professional advisors or those of any of its affiliates (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such information and instructed to
keep such information confidential), (c) upon the request or demand of any Governmental Authority, (d) in response to any order of any court or other Governmental Authority or as may otherwise be required pursuant to any Law, (e) if
requested or required to do so in connection with any litigation or similar proceeding, (f) that has been publicly disclosed, (g) to the National Association of Insurance Commissioners or any similar organization or any nationally
recognized rating agency that requires access to information about a Lender’s investment portfolio in connection with ratings issued with respect to such Lender, or (h) in connection with the exercise of any remedy hereunder or under any
other Loan Document. 
 Each Lender acknowledges that information furnished to it pursuant to this Agreement or the other Loan
Documents may include material non-public information concerning the Borrower and its Affiliates and their related parties or their respective securities, and confirms that it has developed compliance procedures regarding the use of material
non-public information and that it will handle such material non-public information in accordance with those procedures and applicable law, including Federal and state securities laws. 

All information, including requests for waivers and amendments, furnished by the Borrower or the Administrative Agent pursuant to, or in
the course of administering, this Agreement or the other Loan Documents will be syndicate-level information, which may contain material non-public information about the Borrower and its Affiliates and their related parties or their respective
securities. Accordingly, each Lender represents to the Borrower and the Administrative Agent that it has identified in its Administrative Questionnaire a credit contact who may receive information that may contain material non-public information in
accordance with its compliance procedures and applicable law, including Federal and state securities laws. 
 Section 12.12
Interest Rate Limitation. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any
Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which
may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in 

  
 -107-

 
accordance with applicable law, the rate of interest payable in respect of such Loan, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent
lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans
or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender. 

Section 12.13 No Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to make
Loans hereunder are solely for the benefit of the Borrower, and no other Person (including, without limitation, any Restricted Subsidiary, any obligor, contractor, subcontractor, supplier or materialman) shall have any rights, claims, remedies or
privileges hereunder or under any other Loan Document against the Administrative Agent or any Lender for any reason whatsoever. There are no third party beneficiaries. 
 Section 12.14 [Reserved]. 
 Section 12.15 Acknowledgements. The
Borrower hereby acknowledges that: 
 (a) it has been advised by counsel in the negotiation, execution and delivery of this
Agreement and the other Loan Documents; 
 (b) neither the Administrative Agent nor any Lender has any fiduciary relationship
with or duty to the Borrower arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Administrative Agent and Lenders, on one hand, and the Borrower, on the other hand, in connection
herewith or therewith is solely that of debtor and creditor; and 
 (c) no joint venture is created hereby or by the other Loan
Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among the Borrower and the Lenders. 
 Section 12.16 USA Patriot Act Notice. Each 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 to identify the Borrower in accordance with the Act. 
 Section 12.17 Intercreditor Agreement. Reference is
made to the Intercreditor Agreement dated as of December 20, 2012 (as amended, restated, supplemented or otherwise modified from time to time, the “Intercreditor Agreement”), among the Borrower, Wells Fargo Bank, N.A., as First

(b) consents to the subordination of Liens provided for in the Intercreditor Agreement, (c) agrees that it will be bound by and will take no actions contrary to the provisions of the Intercreditor Agreement as if

  
 -108-

foregoing provisions are intended as an inducement to the First Lien Lenders (as defined in the Intercreditor Agreement) to permit the incurrence of Indebtedness under this Agreement and to extend credit to the Borrower and such lenders are intended

 D. Pursuant to a Second Lien Guaranty dated as of December 20, 2012 (as amended, restated or otherwise modified from time to time, the “Guaranty”) made by the Subsidiaries of the
Borrower party thereto from time to time (the “Guarantors”) in favor of the Administrative Agent for the benefit of the Secured Creditors (as defined in the Guaranty), the Guarantors have guaranteed the payment of the Indebtedness,
and pursuant to a Second Lien Security Agreement dated as of December 20, 2012 (as amended, restated or otherwise modified from time to time, the “Security Agreement”) made by the Borrower, the Subsidiaries of Borrower party
thereto from time to time (together with the Borrower, the “Grantors”), and the Agent for the benefit of the Secured Creditors (as defined in the Security Agreement), the Grantors have granted security interests in the collateral
described therein as security for the Indebtedness. 
 E. Section 4.14 of the Guaranty and Section 9.13 of the
Security Agreement provide that additional Material Subsidiaries of the Borrower may become Guarantors under the Guaranty and Grantors under the Security Agreement by execution and delivery of an instrument in the form of this Agreement. The New
Guarantor is executing this Agreement in accordance with the requirements of the Credit Agreement to become a Guarantor under the Guaranty and a Grantor under the Security Agreement. 

Accordingly, the Administrative Agent and the New Guarantor agree as follows: 

1. In accordance with Section 4.14 of the Guaranty, the New Guarantor by its signature below becomes a Guarantor under the Guaranty
with the same force and effect as if 

  
 EXHIBIT H-1

 
originally named as a Guarantor in the Guaranty, and the New Guarantor hereby (a) ratifies, as of the date hereof, and agrees to all the terms and provisions of the Guaranty applicable to it
as a Guarantor thereunder and (b) represents and warrants that the representations and warranties made by it as a Guarantor thereunder are true and correct on and as of the date hereof. Each reference to a “Guarantor” in the Guaranty
will be deemed to include the New Guarantor. 
 2. In accordance with Section 9.13 of the Security Agreement, the New
Guarantor by its signature below becomes a Grantor under the Security Agreement with the same force and effect as if originally named therein as a Grantor, and the New Guarantor hereby (a) ratifies, as of the date hereof, and agrees to all the
terms and provisions of the Security Agreement applicable to it as a Grantor thereunder and (b) represents and warrants that the representations and warranties made by it as a Grantor thereunder are true and correct in all material respects on
and as of the date hereof. The Schedules to the Security Agreement are hereby supplemented by the Schedules attached hereto with respect to the New Guarantor. In furtherance of the foregoing, the New Guarantor, as security for the payment and
performance in full of the Secured Obligations (as defined in the Security Agreement), hereby grants to the Administrative Agent, for the ratable benefit of the Secured Creditors, a security interest in all of the New Guarantor’s right, title
and interest in, to and under the Collateral (as defined in the Security Agreement) of the New Guarantor. Each reference to a “Grantor” in the Security Agreement will be deemed to include the New Guarantor. 

3. If required, the New Guarantor is, simultaneously with the execution of this Agreement, executing and delivering such Security
Instruments (and such other documents and instruments) as requested by the Administrative Agent in accordance with the Credit Agreement. 
 4. The New Guarantor represents and warrants to the Administrative Agent that: 
 (a) an executed (or conformed) copy of each of the Loan Documents has been made available to a Responsible Officer of the New Guarantor and such Responsible Officer has a duty to and has read these
documents, and has full notice and knowledge of the terms, conditions and effects thereof. The New Guarantor has, independently and without reliance upon any Secured Creditor or any information received from the Secured Creditors, and based upon
such documents and information as the New Guarantor has deemed appropriate, made its own analysis of the transactions contemplated hereby and the Borrower, the Borrower’s business, assets, operations, prospects and condition, financial or
otherwise, and any circumstances which may bear upon such transactions, the Borrower or the obligations and risks undertaken herein with respect to the Indebtedness, and decision to enter into the Guaranty. The New Guarantor has received the advice
of its attorney in entering into the Guaranty and the other Loan Documents to which it is a party. The New Guarantor has not relied and will not rely upon any representations or warranties of the Administrative Agent not embodied in the Guaranty or
any acts heretofore or hereafter taken by the Administrative Agent (including but not limited to any review by the Administrative Agent of the affairs of Borrower). The New Guarantor has adequate means to obtain from the Borrower on a continuing
basis information concerning the financial condition and assets of the Borrower, and the New Guarantor is not relying upon any Secured Creditor to provide (and no Secured Creditor will have a duty to provide) any such information to any Guarantor
either now or in the future; and 

  
 EXHIBIT H-2

 (b) the representations and warranties set forth in Article VII of the
Credit Agreement are incorporated herein by reference, the same as if stated verbatim herein as representations and warranties made by the New Guarantor, and the New Guarantor, jointly and severally represents and warrants that each of such
representations and warranties are true and correct (which representations and warranties shall be deemed to have been renewed at the time of each Loan under the Credit Agreement); provided that each reference in each such representation and
warranty to the Borrower’s knowledge shall, for the purposes of Section 4(b), be deemed to be a reference to such New Guarantor’s knowledge. 
 5. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which will constitute an original, but all of which when taken together will
constitute a single contract. 
 6. Except as expressly supplemented by this Agreement, the Guaranty and the Security Agreement
remain in full force and effect. 
 7. THIS AGREEMENT IS GOVERNED BY, AND WILL BE CONSTRUED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF NEW YORK. 
 8. This Agreement is a Loan Document for all purposes of the Credit Agreement and the other Loan
Documents. 
 9. The New Guarantor agrees to execute, acknowledge, deliver, file and record such further certificates,
instruments and documents, and to do all other acts and things as may be requested by the Administrative Agent as necessary or advisable to carry out the intents and purposes of this Agreement, the Security Instruments and the Credit Agreement.

 10. All communications and notices to the New Guarantor under the Guaranty and the Security Agreement must be in writing and
given as provided in Section 4.1 of the Guaranty to the address for the New Guarantor set forth under its signature below. 

11. The New Guarantor shall reimburse the Administrative Agent for its reasonable documented out of-pocket expenses in connection with
this Agreement, including reasonable fees and documented expenses for legal services. 

  
 EXHIBIT H-3
