 (ii) the revenues and proceeds now and hereafter attributable to such
Mortgaged Properties, including the Hydrocarbons, and said products and all payments in lieu, such as “take or pay” payments or settlements; and 
 (iii) all amounts and proceeds hereafter payable to or to become payable to the Mortgagor or now or hereafter relating to any part of such Mortgaged Properties and all amounts, sums, monies, revenues and
income which become payable to the Mortgagor from, or with respect to, any of the Mortgaged Properties, present or future, now or hereafter constituting a part of the Hydrocarbon Interests. 

(b) The Hydrocarbons and products are to be delivered into pipe lines connected with the Mortgaged Property, or to the
purchaser thereof, to the credit of the Mortgagee, for its benefit and the benefit of the Secured Parties, free and clear of all taxes, charges, costs and expenses; and, subject to the following sentence, all such revenues and proceeds shall be paid
directly to the Mortgagee, at its offices in Houston, Texas, with no duty or obligation of any party paying the same to inquire into the rights of the Mortgagee to receive the 

  
 -8-

 
same, what application is made thereof, or as to any other matter. Notwithstanding anything to the contrary contained herein, so long as no Event of Default shall have occurred and is continuing,
Mortgagor shall have the right to collect all revenues and proceeds attributable to the Hydrocarbons that accrue to the Oil and Gas Properties or the products obtained or processed therefrom, as well as any Liens and security interests securing any
sales of said Hydrocarbons and to retain, use and enjoy same. 
 (c) Subject to the last sentence of clause
(b) above, the Mortgagor agrees to perform all such acts, and to execute all such further assignments, transfers and division orders and other instruments as may be required or desired by the Mortgagee or any party in order to have said
proceeds and revenues so paid to the Mortgagee. In addition to any and all rights of a secured party under Sections 9.607 and 9.609 of the Applicable UCC, and subject to clause (b) above, the Mortgagee is fully authorized to receive and receipt
for said revenues and proceeds; to endorse and cash any and all checks and drafts payable to the order of the Mortgagor or the Mortgagee for the account of the Mortgagor received from or in connection with said revenues or proceeds and to hold the
proceeds thereof in a Deposit Account with the Mortgagee or other acceptable commercial bank as additional collateral securing the Secured Obligations; and to execute transfer and division orders in the name of the Mortgagor, or otherwise, with
warranties binding the Mortgagor. All proceeds received by the Mortgagee pursuant to this grant and assignment shall be applied as provided in Section 5.14. 

(d) The Mortgagee shall not be liable for any delay, neglect or failure to effect collection of any proceeds or to take
any other action in connection therewith or hereunder; but the Mortgagee shall have the right, at its election, in the name of the Mortgagor or otherwise, to prosecute and defend any and all actions or legal proceedings deemed advisable by the
Mortgagee in order to collect such funds and to protect the interests of the Mortgagee and/or the Mortgagor, with all costs, expenses and attorneys’ fees incurred in connection therewith being paid by the Mortgagor. 

(e) The Mortgagor hereby appoints the Mortgagee as its attorney-in-fact solely in order to pursue any and all rights of
the Mortgagor to Liens in the Hydrocarbons securing payment of proceeds of runs attributable to the Hydrocarbons. In addition to the Liens granted to the Trustee and/or the Mortgagee in Section 2.01(e), the Mortgagor hereby further transfers
and assigns to the Mortgagee any and all such Liens, security interests, financing statements or similar interests of the Mortgagor attributable to its interest in the As-Extracted Collateral, any other Hydrocarbons and proceeds of runs therefrom
arising under or created by said statutory provision, judicial decision or otherwise. The power of attorney granted to the Mortgagee in this Section 3.01, being coupled with an interest, shall be irrevocable until the Secured Obligations have
been Paid In Full In Cash. 
 Section 3.02 No Modification of Payment Obligations. Nothing herein contained shall modify
or otherwise alter the obligation of the Mortgagor to make prompt payment of all amounts constituting Secured Obligations when and as the same become due regardless of whether the proceeds of the As-Extracted Collateral and Hydrocarbons are
sufficient to pay the same and the rights provided in accordance with the foregoing assignment provision shall be cumulative of all other security of any and every character now or hereafter existing to secure payment of the Secured Obligations.
Nothing in this Article III is intended to be an acceptance of collateral in satisfaction of the Secured Obligations.

 Section 3.03 Rights and Title of Consignee. In addition to the rights, titles and
interests hereby conveyed pursuant to Section 2.01, the Mortgagor hereby grants to the Mortgagee those Liens given to interest owners of Hydrocarbons to secure the obligations of purchasers at the wellhead, including those rights provided in
Tex. Bus. & Com. Code Ann. §9.343 (Vernon Supp. 1989) (“Tex. UCC”), as amended from time to time. 

ARTICLE IV 

REPRESENTATIONS, WARRANTIES AND COVENANTS 
 The Mortgagor hereby represents, warrants and covenants as follows: 
 Section
4.01 Title. To the extent of the undivided interests specified on Exhibit A, the Mortgagor has good and defensible title to and is possessed of the Hydrocarbon Interests and has good title to the UCC Collateral, in both instances except for
Permitted Encumbrances. 
 Section 4.02 Defend Title. This Mortgage is, and always will be kept, a second priority Lien
(subordinate only to the first priority interest represented by the Senior Mortgage and Permitted Liens entitled to priority as a matter of law) upon the Collateral; provided that Permitted Encumbrances may exist, but no intent to subordinate the
priority of the Liens created hereby is intended or inferred by such existence. The Mortgagor will warrant and defend the title to the Collateral against the claims and demands of all other Persons whomsoever and will maintain and preserve the Lien
created hereby (and its priority) until the Secured Obligations shall be Paid In Full In Cash. If (i) an adverse claim be made against or a cloud develop upon the title to any part of the Collateral other than a Permitted Encumbrance or
(ii) any Person, including the holder of a Permitted Encumbrance, shall challenge the priority or validity of the Liens created by this Mortgage, then the Mortgagor agrees to promptly defend against such adverse claim, take appropriate action
to remove such cloud or subordinate such Permitted Encumbrance, in each case, at the Mortgagor’s sole cost and expense. 

Section 4.03 Not a Foreign Person. The Mortgagor is not a “foreign person” within the meaning of the Code, Sections 1445
and 7701 (i.e. the Mortgagor is not a non-resident alien, foreign corporation, foreign partnership, foreign trust or foreign estate as those terms are defined in the Code and any regulations promulgated thereunder). 

Section 4.04 Revenue and Cost Bearing Interest. The Mortgagor’s ownership of the undivided interests in the wells specified
on Exhibit A will, after giving full effect to all Permitted Encumbrances, afford the Mortgagor not less than those net interests (expressed as a fraction, percentage or decimal) in the production from or which is allocated to such undivided
interests specified as Net Revenue Interest (as specified on Exhibit A) on attached Exhibit A except for periods in which the Mortgagor has elected to not participate in well operations (which allows other owners to recoup a multiple of their costs
of participation before the Mortgagor will again be entitled to receive its share of production) and will cause the Mortgagor to bear not more than that portion (expressed as a fraction, percentage or decimal), specified as Working Interest on
Exhibit A, of the costs of drilling, developing and operating the wells identified on Exhibit A except to the extent of any proportionate corresponding increase in the Net Revenue Interest. 

  
 -10-

 Section 4.05 Rentals Paid; Leases in Effect. Except as otherwise set forth in the
Indenture or as could not reasonably be expected to have a Material Adverse Effect, all rentals and royalties due and payable in accordance with the terms of any leases or subleases comprising a part of the Mortgaged Property have been duly paid or
provided for, and all leases or subleases comprising a part of the Oil and Gas Property are in full force and effect. 

Section 4.06 Failure to Perform. The Mortgagor agrees that if it fails to perform any act or to take any action which it is
required to perform or take hereunder or pay any money which the Mortgagor is required to pay hereunder, each of the Mortgagee and the Trustee, in the Mortgagor’s name or its or their own name, may, but shall not be obligated to, perform or
cause to perform such act or take such action or pay such money, and any expenses so incurred by either of them and any money so paid by either of them shall be a demand obligation owing by the Mortgagor to the Mortgagee or the Trustee, as the case
may be, and each of the Mortgagee and the Trustee, upon making such payment, shall be subrogated to all of the rights of the Person receiving such payment. Each amount due and owing by the Mortgagor to each of the Mortgagee and the Trustee pursuant
to this Mortgage shall bear interest from the date of such expenditure or payment to such Person until paid at the Post-Default Rate. 
 ARTICLE V 
 RIGHTS AND REMEDIES 

Section 5.01 Event of Default. An Event of Default under the Indenture shall be an “Event of Default” under this
Mortgage. 
 Section 5.02 Foreclosure and Sale. 

(a) If an Event of Default shall occur and be continuing, to the extent provided by applicable law, the Mortgagee shall
have the right and option to proceed with foreclosure by: (i) with respect to that portion of the Mortgaged Property located in or adjacent to any Deed of Trust State directing the Trustee to proceed, and (ii) with respect to that portion
of the Mortgaged Property located in or adjacent to any Mortgage State proceeding, with foreclosure and to sell all or any portion of such Mortgaged Property at one or more sales, as an entirety or in parcels, at such place or places in otherwise
such manner and upon such notice as may be required by law, or, in the absence of any such requirement, as the Mortgagee may deem appropriate, and to make conveyance to the purchaser or purchasers. Where the Mortgaged Property is situated in more
than one jurisdiction, notice as above provided shall be posted and filed in all such jurisdictions (if such notices are required by law), and all such Mortgaged Property may be sold in any such jurisdiction and any such notice shall designate the
jurisdiction where such Mortgaged Property is to be sold. Nothing contained in this Section 5.02 shall be construed so as to limit in any way any rights to sell the Mortgaged Property or any portion thereof by private sale if and to the extent
that such private sale is permitted under the laws of the applicable jurisdiction or by public or private sale after entry of a judgment by any court of competent jurisdiction so ordering. The Mortgagor hereby irrevocably appoints the Trustee and
the Mortgagee, with full power of substitution, to be the attorneys-in-fact of the Mortgagor and 

  
 -11-

 
in the name and on behalf of the Mortgagor solely in order to execute and deliver any deeds, transfers, conveyances, assignments, assurances and notices which the Mortgagor ought to execute and
deliver and do and perform any and all such acts and things which the Mortgagor ought to do and perform under the covenants herein contained and generally, to use the name of the Mortgagor in the exercise of all or any of the powers hereby conferred
on the Trustee and/or the Mortgagee. At any such sale: (i) whether made under the power herein contained or any other legal enactment, or by virtue of any judicial proceedings or any other legal right, remedy or recourse, it shall not be
necessary for the Trustee or the Mortgagee, as appropriate, to have physically present, or to have constructive possession of, the Mortgaged Property (the Mortgagor hereby covenanting and agreeing to deliver any portion of the Mortgaged Property not
actually or constructively possessed by the Trustee or the Mortgagee immediately upon his or its demand) and the title to and right of possession of any such property shall pass to the purchaser thereof as completely as if the same had been actually
present and delivered to purchaser at such sale, (ii) each instrument of conveyance executed by the Trustee or the Mortgagee shall contain a general warranty of title, binding upon the Mortgagor and its successors and assigns, (iii) each
and every recital contained in any instrument of conveyance made by the Trustee or the Mortgagee shall conclusively establish the truth and accuracy of the matters recited therein, including, without limitation, nonpayment of the Secured
Obligations, advertisement and conduct of such sale in the manner provided herein and otherwise by law and appointment of any successor trustee hereunder, (iv) any and all prerequisites to the validity thereof shall be conclusively presumed to
have been performed, (v) the receipt of the Trustee, the Mortgagee or such other party or officer making the sale shall be a sufficient discharge to the purchaser or purchasers for its purchase money and no such purchaser or purchasers, or its
assigns or personal representatives, shall thereafter be obligated to see to the application of such purchase money, or be in any way answerable for any loss, misapplication or nonapplication thereof, (vi) to the fullest extent permitted by
law, the Mortgagor shall be completely and irrevocably divested of all of its right, title, interest, claim and demand whatsoever, either at law or in equity, in and to the property sold and such sale shall be a perpetual bar both at law and in
equity against the Mortgagor, and against any and all other persons claiming or to claim the property sold or any part thereof, by, through or under the Mortgagor, and (vii) to the extent and under such circumstances as are permitted by law,
the Mortgagee may be a purchaser at any such sale, and shall have the right, after paying or accounting for all costs of said sale or sales, to credit the amount of the bid upon the amount of the Secured Obligations (in the order of priority set
forth in Section 5.14) in lieu of cash payment. 
 (b) If an Event of Default shall occur and be continuing,
then (i) the Mortgagee shall be entitled to all of the rights, powers and remedies afforded a secured party by the Applicable UCC with reference to the UCC Collateral or (ii) the Trustee or the Mortgagee may proceed as to any Collateral in
accordance with the rights and remedies granted under this Mortgage or applicable law in respect of the Collateral. Such rights, powers and remedies shall be cumulative and in addition to those granted to the Trustee or the Mortgagee under any other
provision of this Mortgage or under any other Loan Document or any Secured Transaction Document. Written notice mailed to the Mortgagor as provided herein at least ten (10) days prior to the date of public sale of any part of the Collateral
which is personal property subject to the provisions of the Applicable UCC, or prior to the date after which private sale of any such part of the Collateral will be made, shall constitute reasonable notice. 

  
 -12-

 Section 5.03 Substitute Trustees and Agents. The Trustee or Mortgagee may appoint or
delegate any one or more persons as agent to perform any act or acts necessary or incident to any sale held by the Trustee or Mortgagee, including the posting of notices and the conduct of sale, but in the name and on behalf of the Trustee or
Mortgagee. If the Trustee or Mortgagee shall have given notice of sale hereunder, any successor or substitute trustee or mortgagee agent thereafter appointed may complete the sale and the conveyance of the property pursuant thereto as if such notice
had been given by the successor or substitute trustee or mortgagee agent conducting the sale. 
 Section 5.04 Judicial
Foreclosure; Receivership. If any of the Secured Obligations shall become due and payable and shall not be promptly paid, the Trustee or the Mortgagee shall have the right and power to proceed by a suit or suits in equity or at law, whether for
the specific performance of any covenant or agreement herein contained or in aid of the execution of any power herein granted, or for any foreclosure hereunder or for the sale of the Collateral under the judgment or decree of any court or courts of
competent jurisdiction, or for the appointment of a receiver pending any foreclosure hereunder or the sale of the Collateral under the order of a court or courts of competent jurisdiction or under executory or other legal process, or for the
enforcement of any other appropriate legal or equitable remedy. Any money advanced by the Trustee and/or the Mortgagee in connection with any such receivership shall be a demand obligation (which obligation the Mortgagor hereby expressly promises to
pay) owing by the Mortgagor to the Trustee and/or the Mortgagee and shall bear interest from the date of making such advance by the Trustee and/or the Mortgagee until paid at the Post-Default Rate. 

Section 5.05 Foreclosure for Installments. The Mortgagee shall also have the option to proceed with foreclosure in satisfaction of
any installments of the Secured Obligations which have not been paid when due either through the courts or by directing the Trustee to proceed with foreclosure in satisfaction of the matured but unpaid portion of the Secured Obligations as if under
a full foreclosure, conducting the sale as herein provided and without declaring the entire principal balance and accrued interest and other Secured Obligations then due; such sale may be made subject to the unmatured portion of the Secured
Obligations, and any such sale shall not in any manner affect the unmatured portion of the Secured Obligations, but as to such unmatured portion of the Secured Obligations this Mortgage shall remain in full force and effect just as though no sale
had been made hereunder. It is further agreed that several sales may be made hereunder without exhausting the right of sale for any unmatured part of the Secured Obligations, it being the purpose hereof to provide for a foreclosure and sale of the
security for any matured portion of the Secured Obligations without exhausting the power to foreclose and sell the Mortgaged Property for any subsequently maturing portion of the Secured Obligations. 

Section 5.06 Separate Sales. The Collateral may be sold in one or more parcels and to the extent permitted by applicable law in
such manner and order as the Mortgagee, in its sole discretion, may elect, it being expressly understood and agreed that the right of sale arising out of any Event of Default shall not be exhausted by any one or more sales. 

Section 5.07 Possession of Mortgaged Property. If an Event of Default shall have occurred and be continuing, then, to the extent
permitted by applicable law, the Trustee or the Mortgagee shall have the right and power to enter into and upon and take possession of all or any part of the Collateral in the possession of the Mortgagor, its successors or assigns, or its or their

  
 -13-

 
agents or servants, and may exclude the Mortgagor, its successors or assigns, and all persons claiming under the Mortgagor, and its or their agents or servants wholly or partly therefrom; and,
holding the same, the Mortgagee may use, administer, manage, operate and control the Collateral and conduct the business thereof to the same extent as the Mortgagor, its successors or assigns, might at the time do and may exercise all rights and
powers of the Mortgagor, in the name, place and stead of the Mortgagor, or otherwise as the Mortgagee shall deem best. All costs, expenses and liabilities of every character incurred by the Trustee and/or the Mortgagee in administering, managing,
operating, and controlling the Mortgaged Property shall constitute a demand obligation (which obligation the Mortgagor hereby expressly promises to pay) owing by the Mortgagor to the Trustee and/or the Mortgagee and shall bear interest from date of
expenditure until paid at the Post-Default Rate. 
 Section 5.08 Occupancy After Foreclosure. In the event there is a
foreclosure sale hereunder and at the time of such sale the Mortgagor or the Mortgagor’s heirs, devisees, representatives, successors or assigns or any other person claiming any interest in the Collateral by, through or under the Mortgagor, are
occupying or using the Mortgaged Property or any part thereof, each and all shall immediately become the tenant of the purchaser at such sale, which tenancy shall be a tenancy from day to day, terminable at the will of either the landlord or tenant,
or at a reasonable rental per day based upon the value of the property occupied, such rental to be due daily to the purchaser; to the extent permitted by applicable law, the purchaser at such sale shall, notwithstanding any language herein
apparently to the contrary, have the sole option to demand immediate possession following the sale or to permit the occupants to remain as tenants at will. In the event the tenant fails to surrender possession of said property upon demand, the
purchaser shall be entitled to institute and maintain a summary action for possession of the Mortgaged Property (such as an action for forcible entry and detainer) in any court having jurisdiction. 

Section 5.09 Remedies Cumulative, Concurrent and Nonexclusive. Every right, power, privilege and remedy herein given to the
Trustee or the Mortgagee shall be cumulative and in addition to every other right, power and remedy herein specifically given or now or hereafter existing in equity, at law or by statute (including specifically those granted by the Applicable UCC in
effect and applicable to the Collateral or any portion thereof). Each and every right, power, privilege and remedy whether specifically herein given or otherwise existing may be exercised from time to time and so often and in such order as may be
deemed expedient by the Trustee or the Mortgagee, and the exercise, or the beginning of the exercise, or the abandonment, of any such right, power, privilege or remedy shall not be deemed a waiver of the right to exercise, at the same time or
thereafter any other right, power, privilege or remedy. No delay or omission by the Trustee or the Mortgagee or any Other Secured Person in the exercise of any right, power or remedy shall impair any such right, power, privilege or remedy or operate
as a waiver thereof or of any other right, power, privilege or remedy then or thereafter existing. 
 Section 5.10
Discontinuance of Proceedings. If the Trustee or the Mortgagee shall have proceeded to invoke any right, remedy or recourse permitted hereunder or under any Secured Transaction Document or available at law and shall thereafter elect to
discontinue or abandon same for any reason, then it shall have the unqualified right so to do and, in such an event, the parties shall be restored to their former positions with respect to the Secured Obligations, this Mortgage, the Indenture, the
Collateral and otherwise, and the rights, remedies, recourses and powers of the Trustee and the Mortgagee, as applicable, shall continue as if same had never been invoked. 

  
 -14-

 Section 5.11 No Release of Obligations. Neither the Mortgagor, any Subsidiary
Guarantor nor any other person hereafter obligated for payment of all or any part of the Secured Obligations shall be relieved of such obligation by reason of: (a) the failure of the Trustee to comply with any request of the Mortgagor, or any
Subsidiary Guarantor or any other Person so obligated to foreclose the Lien of this Mortgage or to enforce any provision hereunder or under the Indenture; (b) the release, regardless of consideration, of the Mortgaged Property or any portion
thereof or interest therein or the addition of any other property to the Mortgaged Property; (c) any agreement or stipulation between any subsequent owner of the Mortgaged Property and the Mortgagee extending, renewing, rearranging or in any
other way modifying the terms of this Mortgage without first having obtained the consent of, given notice to or paid any consideration to the Mortgagor, any Subsidiary Guarantor or such other Person, and in such event the Mortgagor, Subsidiary
Guarantor and all such other persons shall continue to be liable to make payment according to the terms of any such extension or modification agreement unless expressly released and discharged in writing by the Mortgagee; or (d) by any other
act or occurrence save and except if the Secured Obligations are Paid In Full In Cash and any other obligations hereunder or under the Indenture are completely fulfilled. 
 Section 5.12 Release of and Resort to Collateral. The Mortgagee may release, regardless of consideration, any part of the Collateral without, as to the remainder, in any way impairing, affecting,
subordinating or releasing the Lien created in or evidenced by this Mortgage or its stature as a second Lien (subordinate only to the first priority interest represented by the Senior Mortgage and any other Permitted Liens entitled to priority as a
matter of law) in and to the Collateral, and without in any way releasing or diminishing the liability of any Person liable for the repayment of the Secured Obligations. For payment of the Secured Obligations, the Mortgagee may resort to any other
security therefor held by the Mortgagee or the Trustee in such order and manner as the Mortgagee may elect. 
 Section 5.13
Waiver of Redemption, Notice and Marshalling of Assets, Etc. To the fullest extent permitted by law, the Mortgagor hereby irrevocably and unconditionally waives and releases (a) all benefits that might accrue to the Mortgagor by virtue of
any present or future moratorium law or other law exempting the Collateral from attachment, levy or sale on execution or providing for any appraisement, valuation, stay of execution, exemption from civil process, redemption or extension of time for
payment; (b) all notices of any Event of Default or of the Mortgagee’s or any other secured Person’s intention to accelerate maturity of the Secured Obligations or of any election to exercise or any actual exercise of any right,
remedy or recourse provided for hereunder or under any Secured Transaction Document or available at law; and (c) any right to a marshalling of assets or a sale in inverse order of alienation. If any law referred to in this Mortgage and now in
force, of which the Mortgagor or its successor or successors might take advantage despite the provisions hereof, shall hereafter be repealed or cease to be in force, such law shall thereafter be deemed not to constitute any part of the contract
herein contained or to preclude the operation or application of the provisions hereof. If the laws of any state which provides for a redemption period do not permit the redemption period to be waived, the redemption period shall be specifically
reduced to the minimum amount of time allowable by statute. 

  
 -15-

 Section 5.14 Application of Proceeds. The proceeds of any sale of the Mortgaged
Property or any part thereof and all other monies received in any proceedings for the enforcement hereof or otherwise, whose application has not elsewhere herein been specifically provided for, shall be applied: 

(a) First, to the payment of all reasonable expenses incurred by the Trustee or the Mortgagee incident to the enforcement
of this Mortgage, the Indenture or any Secured Transaction Document to collect any portion of the Secured Obligations (including, without limiting the generality of the foregoing, expenses of any entry or taking of possession, of any sale, of
advertisement thereof, and of conveyances, and court costs, compensation of agents and employees, legal fees and a reasonable commission to the Trustee acting, if applicable), and to the payment of all other reasonable charges, expenses, liabilities
and advances incurred or made by the Trustee or the Mortgagee under this Mortgage or in executing any trust or power hereunder; and 
 (b) Second, as set forth in Section 4.10 of the Indenture. 
 Section 5.15
Resignation of Operator. In addition to all rights and remedies under this Mortgage, at law and in equity, if any Event of Default shall occur and the Trustee or the Mortgagee shall exercise any remedies under this Mortgage with respect to any
portion of the Mortgaged Property (or the Mortgagor shall transfer any Mortgaged Property “in lieu of” foreclosure) whereupon the Mortgagor is divested of its title to any of the Collateral, the Mortgagee shall have the right to request
that any operator of any Mortgaged Property which is either the Mortgagor or any Affiliate of the Mortgagor to resign as operator under the joint operating agreement applicable thereto, and no later than 60 days after receipt by the Mortgagor of any
such request, the Mortgagor shall resign (or cause such other Person to resign) as operator of such Collateral. 
 Section
5.16 Indemnity. THE INDEMNIFIED PARTIES SHALL NOT BE LIABLE, IN CONNECTION WITH ANY ACTION TAKEN, FOR ANY LOSS SUSTAINED BY THE MORTGAGOR RESULTING FROM AN ASSERTION THAT THE MORTGAGEE HAS RECEIVED FUNDS FROM THE PRODUCTION OF HYDROCARBONS
CLAIMED BY THIRD PERSONS OR ANY ACT OR OMISSION OF ANY INDEMNIFIED PARTY IN ADMINISTERING, MANAGING, OPERATING OR CONTROLLING THE MORTGAGED PROPERTY INCLUDING SUCH LOSS WHICH MAY RESULT FROM THE ORDINARY NEGLIGENCE OF AN INDEMNIFIED PARTY
UNLESS SUCH LOSS IS CAUSED BY THE WILLFUL MISCONDUCT OR GROSS NEGLIGENCE OF THE INDEMNIFIED PARTY SEEKING INDEMNITY. NO INDEMNIFIED PARTY WILL BE OBLIGATED TO PERFORM OR DISCHARGE ANY OBLIGATION, DUTY OR LIABILITY OF THE MORTGAGOR. THE MORTGAGOR
SHALL AND DOES HEREBY AGREE TO INDEMNIFY EACH INDEMNIFIED PARTY FOR, AND TO HOLD EACH INDEMNIFIED PARTY HARMLESS FROM, ANY AND ALL LIABILITY, LOSS OR DAMAGE WHICH MAY OR MIGHT BE INCURRED BY ANY INDEMNIFIED PARTY BY REASON OF THIS MORTGAGE OR THE
EXERCISE OF RIGHTS OR REMEDIES HEREUNDER. IF ANY INDEMNIFIED PARTY SHALL MAKE ANY EXPENDITURE ON ACCOUNT OF ANY SUCH LIABILITY, LOSS OR DAMAGE, THE AMOUNT THEREOF, INCLUDING COSTS, EXPENSES AND REASONABLE ATTORNEYS’ FEES, SHALL BE A DEMAND

  
 -16-

 
OBLIGATION (WHICH OBLIGATION THE MORTGAGOR HEREBY EXPRESSLY PROMISES TO PAY) OWING BY THE MORTGAGOR TO SUCH INDEMNIFIED PARTY AND SHALL BEAR INTEREST FROM THE DATE EXPENDED UNTIL PAID AT THE
POST-DEFAULT RATE. THE MORTGAGOR HEREBY ASSENTS TO, RATIFIES AND CONFIRMS ANY AND ALL ACTIONS OF EACH INDEMNIFIED PARTY WITH RESPECT TO THE MORTGAGED PROPERTY TAKEN UNDER AND IN COMPLIANCE WITH THE TERMS OF THIS MORTGAGE. THE LIABILITIES OF THE
MORTGAGOR AS SET FORTH IN THIS SECTION 5.16 SHALL SURVIVE THE TERMINATION OF THIS MORTGAGE. 
 ARTICLE VI 

THE TRUSTEE 
 Section 6.01 Duties, Rights, and Powers of Trustee. The Trustee shall have no duty to see to any recording, filing or registration of this Mortgage or any other instrument in addition or
supplemental thereto, or to give any notice thereof, or to see to the payment of or be under any duty in respect of any tax or assessment or other governmental charge which may be levied or assessed on the Mortgaged Property, or any part thereof, or
against the Mortgagor, or to see to the performance or observance by the Mortgagor of any of the covenants and agreements contained herein. The Trustee shall not be responsible for the execution, acknowledgment or validity of this Mortgage or of any
instrument in addition or supplemental hereto or for the sufficiency of the security purported to be created hereby, and makes no representation in respect thereof or in respect of the rights of the Mortgagee. The Trustee shall have the right to
advise with counsel upon any matters arising hereunder and shall be fully protected in relying as to legal matters on the advice of counsel. The Trustee shall not incur any personal liability hereunder except for the Trustee’s own willful
misconduct; and the Trustee shall have the right to rely on any instrument, document or signature authorizing or supporting any action taken or proposed to be taken by him hereunder, believed by him in good faith to be genuine. 

Section 6.02 Successor Trustee. The Trustee may resign by written notice addressed to the Mortgagee or be removed at any time with
or without cause by an instrument in writing duly executed on behalf of the Mortgagee. In case of the death, resignation or removal of the Trustee, a successor may be appointed by the Mortgagee by instrument of substitution complying with any
applicable Governmental Requirements, or, in the absence of any such requirement, without formality other than appointment and designation in writing. Written notice of such appointment and designation shall be given by the Mortgagee to the
Mortgagor, but the validity of any such appointment shall not be impaired or affected by failure to give such notice or by any defect therein. Such appointment and designation shall be full evidence of the right and authority to make the same and of
all the facts therein recited. Upon the making of any such appointment and designation, this Mortgage shall vest in the successor all the estate and title in and to all of the Mortgaged Property in or adjacent to any Deed of Trust State, and the
successor shall thereupon succeed to all of the rights, powers, privileges, immunities and duties hereby conferred upon the Trustee named herein, and one such appointment and designation shall not exhaust the right to appoint and designate an
additional successor but such right may be exercised repeatedly until the Secured Obligations are Paid In Full In Cash. To facilitate the administration of the duties hereunder, the Mortgagee may appoint multiple trustees to serve in such capacity
or in such jurisdictions as the Mortgagee may designate. 

  
 -17-

 Section 6.03 Retention of Moneys. All moneys received by the Trustee shall, until
used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated in any manner from any other moneys (except to the extent required by law) and the Trustee shall be under no liability for
interest on any moneys received by him hereunder. 
 ARTICLE VII 

MISCELLANEOUS 
 Section 7.01 Instrument Construed as Mortgage, Etc. With respect to any portions of the Mortgaged Property located in or adjacent to any State or other jurisdiction the laws of which do not provide
for the use or enforcement of a deed of trust or the office, rights and authority of the Trustee as herein provided, the general language of conveyance hereof to the Trustee is intended and the same shall be construed as words of mortgage unto and
in favor of the Mortgagee and the rights and authority granted to the Trustee herein may be enforced and asserted by the Mortgagee in accordance with the laws of the jurisdiction in which such portion of the Mortgaged Property is located and the
same may be foreclosed at the option of the Mortgagee as to any or all such portions of the Mortgaged Property in any manner permitted by the laws of the jurisdiction in which such portions of the Mortgaged Property is situated. This Mortgage may be
construed as a mortgage, deed of trust, conveyance, assignment, security agreement, fixture filing, pledge, financing statement, hypothecation or contract, or any one or more of them, in order fully to effectuate the Lien hereof and the purposes and
agreements herein set forth. 
 Section 7.02 Releases. 

(a) Full Release. If all Secured Obligations (other than amounts in respect of indemnification, expense,
reimbursement, yield protection or tax gross-up for which no claim has been made) shall be Paid In Full In Cash, the Mortgagee shall forthwith cause satisfaction and discharge of this Mortgage to be entered upon the record at the expense of the
Mortgagor and shall execute and deliver or cause to be executed and delivered such instruments of satisfaction and reassignment as may be appropriate. Otherwise, this Mortgage shall remain and continue in full force and effect. 

(b) Partial Release. If any of the Mortgaged Property shall be sold, transferred or otherwise disposed of by the

desirable for the release of the Liens created hereby on the Mortgaged Property. At the request and sole expense of the Mortgagor, the Mortgagor shall be released from its obligations hereunder in the event that all of the Equity Interests of the

 (c) Possession of Notes. The Mortgagor acknowledges and agrees that
possession of any Note (or any replacements of any said Note or other instrument evidencing any part of the Secured Obligations) at any time by the Mortgagor or any other guarantor shall not in any manner extinguish the Secured Obligations or this
Mortgage, and the Mortgagor shall have the right to issue and reissue any of the Notes from time to time as its interest or as convenience may require, without in any manner extinguishing or affecting the Secured Obligations or the Lien of this
Mortgage. 
 Section 7.03 Severability. If any provision hereof is invalid or unenforceable in any jurisdiction, the
other provisions hereof shall remain in full force and effect in such jurisdiction and the remaining provisions hereof shall be liberally construed in favor of the Trustee, the Mortgagee and the Secured Parties in order to effectuate the provisions
hereof. The invalidity or unenforceability of any provision hereof in any jurisdiction shall not affect the validity or enforceability of any such provision in any other jurisdiction. 

Section 7.04 Successors and Assigns. The terms used to designate any party or group of persons shall be deemed to include the
respective heirs, legal representatives, successors and assigns of such Persons. 
 Section 7.05 Satisfaction of Prior

the Mortgagor’s request, and (b) the Mortgagee and the holders of Second Lien Notes shall be subrogated to any and all rights and Liens owned by any owner or holder of such outstanding Liens, irrespective of whether said Liens are or have
been released. It is expressly understood that, in consideration of the payment of such other indebtedness, the Mortgagor hereby waives and releases all demands and causes of action for offsets and payments to, upon and in connection with the said
indebtedness. This Mortgage is made with full substitution and subrogation of the Trustee and the Mortgagee and his successors in this trust and his and their assigns in and to all covenants and warranties by others heretofore given or made in
respect of the Mortgaged Property or any part thereof. 
 Section 7.06 Application of Payments to Certain Obligations. If
any part of the Secured Obligations cannot be lawfully secured by this Mortgage or if any part of the Mortgaged Property cannot be lawfully subject to the Lien hereof to the full extent of the Secured Obligations, then all payments made shall be
applied on said Secured Obligations first in discharge of that portion thereof which is not secured by this Mortgage. 

Section 7.07 Nature of Covenants. The covenants and agreements herein contained shall constitute covenants running with the land
and interests covered or affected hereby and shall be binding upon the heirs, legal representatives, successors and assigns of the parties hereto.

service) at the addresses specified in Section 7.12 (unless changed by similar notice in writing given by the particular party whose address is to be changed). Any such notice or communication shall be deemed to have been given either at the
time of personal delivery or, in the case of delivery at the address and in the manner provided herein, upon receipt; provided that, service of notice as required by the laws of any state in which portions of the Mortgaged Property may be situated
shall for all purposes be deemed appropriate and sufficient with the giving of such notice. 
 Section 7.09 Counterparts.
This Mortgage is being executed in several counterparts, all of which are identical, except that to facilitate recordation, if the Mortgaged Property is situated in more than one county or parish, descriptions of only those portions of the Mortgaged
Property located in the county or parish in which a particular counterpart is recorded shall be attached as Exhibit A to such counterpart. Each of such counterparts shall for all purposes be deemed to be an original and all such counterparts shall
together constitute but one and the same instrument. Complete copies of this Mortgage containing the entire Exhibit A have been retained by the Mortgagee. 
 Section 7.10 Governing Law. Insofar as permitted by otherwise applicable law, this Mortgage shall be construed under and governed by the laws of the State of Texas; provided, however, that, with
respect to any portion of the Mortgaged Property located outside of the State of Texas, the laws of the place in which such property is located shall apply to the extent of procedural and substantive matters relating only to the creation,
perfection, foreclosure of Liens and enforcement of rights and remedies against the Mortgaged Property. 
 Section 7.11
Financing Statement; Fixture Filing. This Mortgage shall be effective as a financing statement filed as a fixture filing with respect to all Fixtures included within the Mortgaged Property and is to be filed or filed for record in the real
estate records, mortgage records or other appropriate records of each jurisdiction where any part of the Mortgaged Property (including said fixtures) are situated. This Mortgage shall also be effective as a financing statement covering As-Extracted
Collateral (including oil and gas and all other substances of value which may be extracted from the ground) and accounts financed at the wellhead or minehead of wells or mines located on the properties subject to the Applicable UCC and is to be
filed for record in the real estate records, UCC records or other appropriate records of each jurisdiction where any part of the Mortgaged Property is situated. 
 Section 7.12 Execution of Financing Statements. Pursuant to the Applicable UCC, the Mortgagor authorizes the Mortgagee, its counsel or its representative, at any time and from time to time, to file
or record financing statements, continuation statements, amendments thereto and other filing or recording documents or instruments with respect to the Mortgaged Property without the signature of the Mortgagee in such form and in such offices as the
Mortgagee reasonably determines appropriate to perfect the security interests of the Mortgagee under this Agreement. The Mortgagor also authorizes the Mortgagee, its counsel or its representative, at any time and from time to time, to file or record
such financing statements that describe the collateral covered thereby as “all assets of the Mortgagee”, “all personal property of the Mortgagee” or words of similar effect. The Mortgagor shall pay all costs associated with the
filing of such instruments.

 ARTICLE II 
 THE CREDITS 

Section 2.01. Commitments. Subject to the terms and conditions set forth herein, each Lender agrees to make Loans to the
Borrower during the Availability Period in an aggregate principal amount that will not result in (a) such Lender’s Revolving Credit Exposure exceeding such Lender’s Commitment less such Lender’s Applicable Percentage of the
outstanding principal amount of the Existing Senior Notes at such time, or (b) the total Revolving Credit Exposures exceeding the total Commitments less the outstanding principal amount of the Existing Senior Notes at such time. Within the
foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, repay and reborrow the Loans. 
 Section 2.02. Loans and Borrowings. 
 (a) Borrowings; Several
Obligations. Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve
any other Lender of its obligations hereunder; provided that the Commitments 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 any exercise of such option shall
not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. 
 (c) Minimum
Amounts; 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 $500,000; provided that an ABR Borrowing 

  
 23 

 
may be in an aggregate amount that is equal to the entire unused balance of the total Commitments or that is required to finance the reimbursement of an LC Disbursement as contemplated by
Section 2.08(e). Borrowings of more than one Type may be outstanding at the same time, provided that there shall not at any time be more than a total of five (5) Eurodollar Borrowings outstanding unless the Administrative Agent otherwise
agrees. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

 (d) Notes. The Loans made by each Lender shall be evidenced by a single promissory note of the Borrower in
substantially the form of Exhibit A, dated, in the case of (i) any Lender party hereto as of the date of this Agreement, as of the date of this Agreement or (ii) any Lender that becomes a party hereto pursuant to an Assignment and
Assumption, as of the effective date of the Assignment and Assumption, payable to such Lender in a principal amount equal to its Maximum Credit Amount as in effect on such date, and otherwise duly completed. In the event that any Lender’s
Maximum Credit Amount increases or decreases for any reason (whether pursuant to Section 2.06, Section 12.04(a) or otherwise), the Borrower shall deliver or cause to be delivered on the effective date of such increase or decrease, a new
Note payable to such Lender in a principal amount equal to its Maximum Credit Amount after giving effect to such increase or decrease, and otherwise duly completed. The date, amount, Type, interest rate and, if applicable, Interest Period of each
Loan made by each Lender, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note, and, prior to any transfer, may be endorsed by such Lender on a schedule attached to such Note or any
continuation thereof or on any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect
the validity of such transfer by any Lender of its Note. 
 Section 2.03. Requests for Borrowings. To request a
Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 12:00 noon, Houston time, three Business Days before the date of the proposed Borrowing or
(b) in the case of an ABR Borrowing, not later than 12:00 noon, Houston time, on the date of the proposed Borrowing; provided that no such notice shall be required for any deemed request of an ABR Borrowing to finance the reimbursement
of an LC Disbursement as provided in Section 2.08(e). Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in
substantially the form of Exhibit B and signed by the Borrower. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02: 

(i) the aggregate amount of the requested Borrowing; 

(ii) the date of such Borrowing, which shall be a Business Day; 

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

  
 24 

 (iv) in the case of a Eurodollar Borrowing, the initial Interest Period to
be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; 
 (v) the amount of the then effective Borrowing Base, the current total Revolving Credit Exposures (without regard to the requested Borrowing) and the pro forma total Revolving Credit Exposures (giving
effect to the requested Borrowing); and 
 (vi) the location and number of the Borrower’s account to which
funds are to be disbursed, which shall comply with the requirements of Section 2.05. 
 If no election as to the Type of Borrowing is
specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s
duration. Each Borrowing Request shall constitute a representation that the amount of the requested Borrowing shall not cause the total Revolving Credit Exposures to exceed the total Commitments (i.e., the lesser of the Aggregate Maximum
Credit Amounts and the then effective Borrowing Base). 
 Promptly following receipt of a Borrowing Request in accordance with this
Section 2.03, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing. 

Section 2.04. Interest Elections. 
 (a) Conversion and Continuance. Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial
Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor,
all as provided in this Section 2.04. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans
comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. 
 (b)
Interest Election Requests. To make an election pursuant to this Section 2.04, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under
Section 2.03 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed
promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in substantially the form of Exhibit C and signed by the Borrower. 

  
 25 

 (c) Information in Interest Election Requests. Each telephonic and written Interest
Election Request shall specify the following information in compliance with Section 2.02: 
 (i) the
Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be
specified pursuant to Section 2.04(c)(iii) and (iv) shall be specified for each resulting Borrowing); 

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

 (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and 

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving
effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”. 
 If any such Interest
Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. 

(d) Notice to Lenders by the Administrative Agent. Promptly following receipt of an Interest Election Request, the Administrative
Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing. 
 (e)
Effect of Failure to Deliver Timely Interest Election Request and Events of Default and Borrowing Base Deficiencies on Interest Election. If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar
Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be continued as a Eurodollar Borrowing with an Interest Period of
one month. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing: (i) no 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) and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest
Period applicable thereto. 
 Section 2.05. Funding of Borrowings. 

(a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer
of immediately available funds by 1:00 p.m., Houston 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 of the Borrower maintained with the Administrative Agent in Houston, Texas and designated by the Borrower in the applicable Borrowing Request; provided that ABR Loans
made to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuing Bank. Nothing herein shall be deemed to obligate any Lender to obtain the funds for its Loan in
any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for its Loan in any particular place or manner. 

  
 26 

 (b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have
received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made
such share available on such date in accordance with Section 2.05(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 applicable
Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the
date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative
Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall
constitute such Lender’s Loan included in such Borrowing. 
 Section 2.06. Termination and Reduction of Aggregate
Maximum Credit Amounts. 
 (a) Scheduled Termination of Commitments. Unless previously terminated, the Commitments
shall terminate on the Maturity Date. If at any time the Aggregate Maximum Credit Amounts or the Borrowing Base is terminated or reduced to zero, then the Commitments shall terminate on the effective date of such termination or reduction.

 (b) Optional Termination and Reduction of Aggregate Credit Amounts. 

(i) The Borrower may at any time terminate, or from time to time reduce, the Aggregate Maximum Credit Amounts; provided
that (A) each reduction of the Aggregate Maximum Credit Amounts shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000 and (B) the Borrower shall not terminate or reduce the Aggregate Maximum Credit
Amounts if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.04(b), the total Revolving Credit Exposures would exceed the total Commitments. 

(ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Maximum
Credit Amounts under Section 2.06(b)(i) at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the
Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section 2.06(b)(ii) shall be irrevocable; provided that a notice of termination of the Commitments delivered by
the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative

  
 27 

 
Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Aggregate Maximum Credit Amounts shall be permanent and may not be
reinstated. Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage. 
 Section 2.07. Borrowing Base. 
 (a) Initial Borrowing Base. For
the period from and including the Effective Date to but excluding the first Redetermination Date, the amount of the Borrowing Base shall be $63,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from
time to time pursuant to Section 2.07(e), Section 8.13(c) or Section 9.12(d). 
 (b) Scheduled and Interim
Redeterminations. The Borrowing Base shall be redetermined semi-annually in accordance with this Section 2.07 (a “Scheduled Redetermination”), and, subject to Section 2.07(d), such redetermined Borrowing Base shall
become effective and applicable to the Borrower, the Agents, the Issuing Bank and the Lenders on April 1st and October 1st of each year, commencing April 1, 2012. In addition, the Borrower may, by notifying the Administrative Agent
thereof, and the Administrative Agent may, at the direction of the Required Lenders, by notifying the Borrower thereof, one time during any 6-month period between Scheduled Redeterminations, each elect to cause the Borrowing Base to be redetermined
between Scheduled Redeterminations (an “Interim Redetermination”) in accordance with this Section 2.07. 

(c) Scheduled and Interim Redetermination Procedure. Each Scheduled Redetermination and each Interim Redetermination shall be
effectuated as follows: 
 (i) Upon receipt by the Administrative Agent of (A) the Reserve Report and the
certificate required to be delivered by the Borrower to the Administrative Agent, in the case of a Scheduled Redetermination, pursuant to Section 8.12(a) and (c), and, in the case of an Interim Redetermination, pursuant to Section 8.12(b)
and (c), and (B) such other reports, data and supplemental information, including, without limitation, the information provided pursuant to Section 8.12(c), as may, from time to time, be reasonably requested by the Majority Lenders (the
Reserve Report, such certificate and such other reports, data and supplemental information being the “Engineering Reports”), the Administrative Agent shall evaluate the information contained in the Engineering Reports and shall, in
good faith, propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such information and such other information (including, without limitation, the status of title information with respect to the Oil and Gas
Properties as described in the Engineering Reports and the existence of any other Debt) as the Administrative Agent deems appropriate in its sole discretion and consistent with its normal oil and gas lending criteria as it exists at the particular
time. In no event shall the Proposed Borrowing Base exceed the Aggregate Maximum Credit Amounts. 

  
 28 

 (ii) The Administrative Agent shall notify the Borrower and the Lenders of
the Proposed Borrowing Base (the “Proposed Borrowing Base Notice”): 
  

	 	(A)	in the case of a Scheduled Redetermination (1) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower
pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on or before the March 15th and September 15th of such year following the date of delivery or (2) if the Administrative Agent shall not have received
the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then promptly after the Administrative Agent has received complete Engineering Reports from the Borrower
and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with Section 2.07(c)(i); and 

  

	 	(B)	in the case of an Interim Redetermination, promptly, and in any event, within fifteen (15) days after the Administrative Agent has received the required
Engineering Reports. 

 (iii) Any Proposed Borrowing Base that would increase the Borrowing Base
then in effect must be approved or deemed to have been approved by all of the Lenders (other than Defaulting Lenders) as provided in this Section 2.07(c)(iii); and any Proposed Borrowing Base that would decrease or maintain the Borrowing Base
then in effect must be approved or be deemed to have been approved by the Required Lenders as provided in this Section 2.07(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each Lender shall have fifteen (15) days to agree with
the Proposed Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate Borrowing Base. If at the end of such fifteen (15) days, any Lender has not communicated its approval or disapproval in writing to the
Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing Base. If, at the end of such 15-day period, all of the Lenders (other than Defaulting Lenders), in the case of a Proposed Borrowing Base that would
increase the Borrowing Base then in effect, or the Required Lenders, in the case of a Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect, have approved or deemed to have approved, as aforesaid, then the
Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). If, however, at the end of such 15-day period, all of the Lenders (other than Defaulting Lenders) or the Required Lenders, as
applicable, have not approved or deemed to have approved, as aforesaid, then the Administrative Agent shall poll the Lenders to ascertain the highest Borrowing Base then acceptable to a number of Lenders sufficient to constitute the Required Lenders
and, so long as such amount does not increase the Borrowing Base then in effect, such amount shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). 

  
 29 

 (d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing
Base is approved or is deemed to have been approved by all of the Lenders (other than Defaulting Lenders) or the Required Lenders, as applicable, pursuant to Section 2.07(c)(iii), the Administrative Agent shall notify the Borrower and the
Lenders of the amount of the redetermined Borrowing Base (the “New Borrowing Base Notice”), and such amount shall become the new Borrowing Base, effective and applicable to the Borrower, the Administrative Agent, the Issuing Bank
and the Lenders: 
 (i) in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall
have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the April 1st or October 1st, as applicable, following such notice, or
(B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the Business Day next succeeding
delivery of such notice; and 
 (ii) in the case of an Interim Redetermination, on the Business Day next
succeeding delivery of such notice. 
 Such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date, the next
Interim Redetermination Date or the next adjustment to the Borrowing Base under Section 2.07(e), Section 8.13(c) or Section 9.12(d), whichever occurs first. Notwithstanding the foregoing, no Scheduled Redetermination or Interim
Redetermination shall become effective until the New Borrowing Base Notice related thereto is received by the Borrower. 
 (e)
Reduction of Borrowing Base Upon Termination of Hedge Positions. If the Borrower or any Subsidiary shall terminate or create any off-setting positions in respect of any hedge positions (whether evidenced by a floor, put or Swap Agreement)
upon which the Lenders relied in determining the Borrowing Base, then the Borrowing Base shall be contemporaneously reduced in an amount determined by the Required Lenders equal to the Swap Agreement PV of such terminated or cancelled hedge
positions. 
 Section 2.08. Letters of Credit. 

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of dollar denominated
Letters of Credit for its own account or for the account of any of its Subsidiaries, in a form reasonably acceptable to the Issuing Bank, at any time and from time to time during the Availability Period; provided that the Borrower may not
request the issuance, amendment, renewal or extension of Letters of Credit hereunder if a Borrowing Base Deficiency exists at such time or would exist as a result thereof. In the event of any inconsistency between the terms and conditions of this
Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of
this Agreement shall control. 

  
 30 

 (b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request
the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by
the Issuing Bank) to the Issuing Bank and the Administrative Agent (not less than three (3) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice: 

(i) requesting the issuance of a Letter of Credit or identifying the Letter of Credit to be amended, renewed or extended;

 (ii) specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day);

 (iii) specifying the date on which such Letter of Credit is to expire (which shall comply with
Section 2.08(c)); 
 (iv) specifying the amount of such Letter of Credit; 

(v) specifying the name and address of the beneficiary thereof and such other information as shall be necessary to
prepare, amend, renew or extend such Letter of Credit; and 
 (vi) specifying the amount of the then effective
Borrowing Base and whether a Borrowing Base Deficiency exists at such time, the current total Revolving Credit Exposures (without regard to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of
Credit) and the pro forma total Revolving Credit Exposures (giving effect to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit). 

Each notice shall constitute a representation that after giving effect to the requested issuance, amendment, renewal or extension, as applicable,
(i) the LC Exposure shall not exceed the LC Commitment and (ii) the total Revolving Credit Exposures shall not exceed the total Commitments (i.e. the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base).

 If requested by the Issuing Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank’s standard form in
connection with any request for a Letter of Credit. 
 (c) Expiration Date. Each Letter of Credit shall expire at or
prior to the close of business on the earlier of (i) the date one year after the date of issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date
that is five Business Days prior to the Maturity Date; provided, however, that any Letter of Credit with a one-year term may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date
referred to in clause (ii) above).

 (d) Participations. By the issuance of a Letter of Credit (or an amendment to a
Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a participation in
such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and
unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided
in Section 2.08(e), or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this Section 2.08(d) in respect of
Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default, the existence of a
Borrowing Base Deficiency or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. 

(e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall
reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, Houston time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such
LC Disbursement prior to 10:00 a.m., Houston time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon, Houston time, on (i) the Business Day that the Borrower
receives such notice, if such notice is received prior to 10:00 a.m., Houston time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to
such time on the day of receipt; provided that if such LC Disbursement is not less than $500,000, the Borrower shall, subject to the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby request under
such circumstances, that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing. If
the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof.
Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.05 with respect to Loans made by such
Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following
receipt by the Administrative Agent of any payment from the Borrower pursuant to this Section 2.08(e), the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this
Section 2.08(e) to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse the Issuing Bank for any LC Disbursement
(other than the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement. 

  
 32 

 (f) Obligations Absolute. The Borrower’s obligation to reimburse LC
Disbursements as provided in Section 2.08(e) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of
(i) any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Agreement or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be
forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply
with the terms of such Letter of Credit or any Letter of Credit Agreement, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.08(f),
constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties shall have any
liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding
sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any
error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the
extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure to
exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the
Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised all requisite care in each such determination. In furtherance of the foregoing and without limiting the generality thereof,
the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such
documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such
Letter of Credit. 
 (g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine
all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the
Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to
any such LC Disbursement. 
 (h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, until the
Borrower shall have reimbursed the Issuing Bank for such LC Disbursement (either with its own funds or a Borrowing under Section 2.08(e)), the unpaid amount thereof shall bear interest, for each day from and including the date such LC
Disbursement is made to but excluding the 

  
 33 

 
date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans. Interest accrued pursuant to this Section 2.08(h) shall be for the account of the
Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment. 

(i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the Borrower, the
Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. From and after the effective date of any such replacement, (i) the
successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed
to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of the Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto
and shall continue to have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit. 

(j) Cash Collateralization. If any Event of Default shall occur and be continuing at any time there exists any LC Exposure and the
Borrower receives notice from the Administrative Agent or the Majority Lenders demanding the deposit of cash collateral pursuant to this Section 2.08(j), then the Borrower shall deposit, in an account with the Administrative Agent, in the name
of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to the LC Exposure. If the Borrower is required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment
pursuant to Section 3.04(c), the Borrower shall deposit in such an account an amount equal to the amount of such excess as provided in Section 3.04(c), as of such date plus any accrued and unpaid interest thereon. The obligation to deposit
such cash collateral pursuant to the two preceding sentences shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with
respect to the Borrower or any Subsidiary described in Section 10.01(h) or Section 10.01(i). The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Bank and the Lenders, an exclusive first priority and
continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any and all
investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of
the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrower’s obligation to deposit amounts pursuant to this Section 2.08(j) shall be
absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable
law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower or any of its Subsidiaries may now or hereafter have against any such beneficiary, the Issuing Bank, the Administrative
Agent, the Lenders or any other Person for any reason whatsoever. Such account 

  
 34 

 
shall be held as collateral securing the payment and performance of the Borrower’s and the Guarantor’s obligations under this Agreement and the other Loan Documents. The Administrative
Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of
the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the
Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure
at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other obligations of the Borrower and the Guarantors under this Agreement or the other Loan Documents. If the Borrower is required to provide an amount of cash
collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to
Section 3.04(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived. 

ARTICLE III 

PAYMENTS OF PRINCIPAL AND INTEREST; PREPAYMENTS; FEES 
 Section 3.01. Repayment of Loans. The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan
on the Termination Date. 
 Section 3.02. Interest. 

(a) ABR Loans. The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Margin,
but in no event to exceed the Highest Lawful Rate. 
 (b) Eurodollar Loans. The Loans comprising each Eurodollar
Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate. 

(c) Post-Default Rate and Borrowing Base Deficiency Rate. Notwithstanding the foregoing, (i) if an Event of Default has
occurred and is continuing, or if any principal of or interest on any Loan or any fee or other amount payable by the Borrower or any Guarantor hereunder or under any other Loan Document is not paid when due, whether at stated maturity, upon
acceleration or otherwise, and including any payments in respect of a Borrowing Base Deficiency under Section 3.04(c), then all Loans outstanding, in the case of an Event of Default, and such overdue amount, in the case of a failure to pay
amounts when due, shall bear interest, after as well as before judgment, at a rate per annum equal to two percent (2%) plus the rate applicable to ABR Loans as provided in Section 3.02(a), but in no event to exceed the Highest Lawful Rate,
and (ii) during any Borrowing Base Deficiency, all Loans outstanding at such time shall bear interest, after as well as before judgment, at the rate then applicable to such Loans, plus the Applicable Margin, if any, plus an additional two
percent (2%), but in no event to exceed the Highest Lawful Rate. 

  
 35 

 (d) Interest Payment Dates. Accrued interest on each Loan shall be payable in arrears
on each Interest Payment Date for such Loan and on the Termination Date; provided that (i) interest accrued pursuant to Section 3.02(c) shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other
than an optional prepayment of an ABR Loan prior to the Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, and (iii) in the event of any conversion of any
Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion. 
 (e) Interest Rate Computations. All interest hereunder shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest
shall be computed on the basis of a year of 365 days (or 366 days in a leap year), except that interest computed by reference to the Alternate Base Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each
case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such
determination shall be conclusive absent manifest error, and be binding upon the parties hereto. 
 Section 3.03.
Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing: 
 (a) the
Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate for such Interest Period; or 

(b) the Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate or LIBO Rate, as applicable, for such
Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period; 
 then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the
Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be
ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made either as an ABR Borrowing or at an alternate rate of interest determined by the Majority Lenders as their cost of funds. 

Section 3.04. Prepayments. 
 (a) Optional Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with
Section 3.04(b). 

  
 36 

 (b) Notice and Terms of Optional Prepayment. The Borrower shall notify the
Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, Houston time, three Business Days before the date of prepayment, or
(ii) in the case of prepayment of an ABR Borrowing, not later than 12:00 noon, Houston time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the Borrowing to be prepaid, the prepayment date and the principal
amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.06(b)(ii), then such notice of
prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.06(b)(ii). Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents
thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to
the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 3.02. 
 (c) Mandatory Prepayments. 
 (i) If, after giving effect to
any termination or reduction of the Aggregate Maximum Credit Amounts pursuant to Section 2.06(b), the total Revolving Credit Exposures exceeds the total Commitments, then the Borrower shall (A) prepay the Borrowings on the date of such
termination or reduction in an aggregate principal amount equal to such excess, and (B) if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an
amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). 
 (ii) Upon any
redetermination of the Borrowing Base pursuant to Section 2.07 or adjustment to the amount of the Borrowing Base in accordance with Section 8.13(c), if the aggregate Revolving Credit Exposures of all Lenders exceeds the redetermined or
adjusted Borrowing Base, then the Borrower shall, within 10 Business Days after its receipt of a New Borrowing Base Notice inform the Administrative Agent of the Borrower’s election to: (A) within 30 days following its receipt of such New
Borrowing Base Notice (1) prepay the Loans in an aggregate principal amount equal to such excess and (2) if any excess remains after prepaying all of the Loans as a result of any Letter of Credit Exposure, cash collateralize such excess as
provided in Section 2.08(j) (provided that all payments required to be made pursuant to this Section 4.02(c) must be made on or prior to the Termination Date), (B) prepay the Loans in four equal monthly installments, commencing on the
30th day following its receipt of such New Borrowing Base Notice with each payment being equal to 1/4th of the aggregate principal amount of such excess (provided that all payments required to be made pursuant to this Section 4.02(c) must be
made on or prior to the Termination Date), (C) within 30 days following its receipt of such New Borrowing Base Notice, provide additional collateral in the form of additional Oil and Gas Properties not evaluated in the most recently delivered
Reserve Report or other collateral reasonably acceptable to the Administrative Agent having a Borrowing Base value (as proposed by the Administrative Agent and approved by the Required Lenders) sufficient, after giving effect to any other actions
taken pursuant to this Section 4.02(c) to eliminate any such excess or (D) undertake a combination of clauses (A), (B) and (C). If, 

  
 37 

 
because of Letter of Credit Exposure, a Borrowing Base Deficiency remains after prepaying all of the Loans, the Borrower shall cash collateralize such remaining Borrowing Base Deficiency as
provided in Section 2.08(j). 
 (iii) Upon any adjustments to the Borrowing Base pursuant to
Section 2.07(e) or Section 9.12, if the total Revolving Credit Exposures exceeds the Borrowing Base as adjusted, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such excess, and (B) if
any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). The
Borrower shall be obligated to make such prepayment and/or deposit of cash collateral on the date it or any Subsidiary receives cash proceeds as a result of such termination of a Swap Agreement or disposition; provided that all payments required to
be made pursuant to this Section 3.04(c) must be made on or prior to the Termination Date. 
 (iv) Each
prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied, first, ratably to any ABR Borrowings then outstanding, and, second, to any Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then
outstanding, to each such Eurodollar Borrowing in order of priority beginning with the Eurodollar Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing with the most
number of days remaining in the Interest Period applicable thereto. 
 (v) Each prepayment of Borrowings pursuant
to this Section 3.04(c) shall be applied ratably to the Loans included in the prepaid Borrowings. Prepayments pursuant to this Section 3.04(c) shall be accompanied by accrued interest to the extent required by Section 3.02.

 (d) No Premium or Penalty. Prepayments permitted or required under this Section 3.04 shall be without premium or
penalty, except as required under Section 5.02. 
 Section 3.05. Fees. 

(a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender (other than a
Defaulting Lender to the extent set forth in Section 4.05) a commitment fee, which shall accrue at a rate per annum of 0.50% on the average daily amount of the unused amount of the Commitment of such Lender during the period from and including
the date of this Agreement to but excluding the Termination Date. Accrued commitment fees shall be payable in arrears on the last day of March, June, September and December of each year and on the Termination Date, commencing on the first such date
to occur after the date hereof. All commitment fees shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or
366 days in a leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). 

  
 38 

 (b) Letter of Credit Fees. The Borrower agrees to pay (i) to the Administrative
Agent for the account of each Lender (other than a Defaulting Lender to the extent set forth in Section 4.05) a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Margin used to
determine the interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements which has been funded by such Lender) during the
period from and including the date of this Agreement to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, (ii) to the Issuing Bank a fronting
fee, which shall accrue at the rate of 0.25% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement
to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, provided that in no event shall such fee be less than $125 during any quarter, and (iii) to the Issuing Bank, for
its own account, its standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March,
June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the date of this Agreement; provided that all such fees shall be payable on the
Termination Date and any such fees accruing after the Termination Date shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this Section 3.05(a) shall be payable within 10 days after demand. All participation fees
and fronting fees shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall
be payable for the actual number of days elapsed (including the first day but excluding the last day). 
 (c) Administrative
Agent Fees. The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent. 

(d) Borrowing Base Increase Fees. The Borrower agrees to pay to the Administrative Agent, for the account of each Lender then
party to this Agreement, ratably in accordance with its Applicable Percentage, a Borrowing Base increase fee to be agreed by the Lenders and the Borrower on the occasion of any increase of the Borrowing Base, payable on the effective date of any
such increase to the Borrowing Base. 
 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 reimbursement of LC Disbursements, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00 noon,
Houston time, on the date when due, in immediately available funds and, subject to Section 5.03, 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 

  
 39 

 
purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices specified in Section 12.01, except payments to be made directly to the
Issuing Bank as expressly provided herein and 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 insufficient funds are received by and available to the Administrative
Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled
thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance
with the amounts of principal and unreimbursed LC Disbursements then due to such parties. 
 (c) 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 or participations in LC Disbursements resulting in such Lender receiving
payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements 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 and participations in LC Disbursements 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 and participations in LC Disbursements; 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 or participations in LC Disbursements to
any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively
do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a
direct creditor of the Borrower in the amount of such participation. 
 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 or the Issuing Bank that the Borrower will not make
such payment, the Administrative Agent may assume that the Borrower 

  
 40 

 
has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such
event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing
Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank compensation. 
 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 to Section 2.05(a), Section 2.08(d), Section 2.08(e) or Section 4.02 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. If at any time prior to the acceleration or maturity of the Loans, the Administrative Agent shall receive any payment in respect of principal of a Loan or a reimbursement of an LC Disbursement while one or
more Defaulting Lenders shall be party to this Agreement, the Administrative Agent shall apply such payment first to the Borrowing(s) for which such Defaulting Lender(s) shall have failed to fund its pro rata share until such time as such
Borrowing(s) are paid in full or each Lender (including each Defaulting Lender) is owed its Applicable Percentage of all Loans then outstanding. 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 Guarantors unto and in favor of the Administrative Agent for the benefit of the Lenders of all of the Borrower’s or each Guarantor’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 Secured Obligations and other obligations described therein and secured
thereby. Notwithstanding the assignment contained in such Security Instruments, until the occurrence of an Event of Default, (a) 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 and its Subsidiaries, and (b) 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 Subsidiaries. 
 Section 4.05. Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so
long as such Lender is a Defaulting Lender: 
 (a) commitment fees shall cease to accrue on the unfunded portion of the
Commitment of such Defaulting Lender pursuant to Section 3.05(a); 

  
 41 

 (b) the Commitment of such Defaulting Lender shall not be included in determining whether
all Lenders, the Majority Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 12.02 or any redetermination of the Borrowing Base), provided
that any waiver, amendment or modification that (i) reduces the amount of principal of or the rate at which interest is payable on the Loans, (ii) increases the Defaulting Lender’s Commitment or (iii) extends the dates fixed for
payments of principal or interest on the Loans shall require the approval or consent of such Defaulting Lender; 
 (c) if any LC
Exposure exists at the time a Lender becomes a Defaulting Lender then: 
 (i) all or any part of the LC Exposure
of such Defaulting Lender shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages and this obligation to reallocate shall be absolute and unconditional under any and all circumstances and
irrespective of any setoff, counterclaim or defense to reallocation that any non-Defaulting Lender may have or have had against the Issuing Bank, the Borrower, any Guarantor or any other Lender (including the Defaulting Lender); provided that
such LC Exposure shall be reallocated among the non-Defaulting Lenders only to the extent that (x) the sum of all non-Defaulting Lenders’ Loans and all non-Defaulting Lenders’ LC Exposure plus such Defaulting Lender’s LC
Exposure does not exceed the total of all non-Defaulting Lenders’ Commitments, (y) the sum of each non-Defaulting Lender’s Loans and such non-Defaulting Lender’s LC Exposure plus its reallocated share of such Defaulting
Lender’s LC Exposure does not exceed such non-Defaulting Lender’s Commitment and (z) the conditions set forth in Section 6.02 are satisfied at such time; 

(ii) if the reallocation described in clause (i) cannot, or can only partially, be effected, the Borrower shall,
within one Business Day following notice by the Administrative Agent, cash collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i)) in accordance with procedures set forth
in Section 2.08(j) for so long as such LC Exposure are outstanding; 
 (iii) if the Borrower cash
collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to this Section 4.05(c), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 3.05(b) with respect to such
Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized; 
 (iv) if the LC Exposure of the Defaulting Lenders is reallocated pursuant to Section 4.05(c), then the fees payable to the Lenders pursuant to Section 3.05(b) shall be adjusted in accordance
with such non-Defaulting Lenders’ Applicable Percentages; and 
 (v) to the extent that any Defaulting
Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to Section 4.05(c), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, the portion of Letter of Credit fees payable
under Section 3.05(b) corresponding to such Defaulting Lender’s LC Exposure that are neither so cash collateralized nor reallocated shall be payable to the Issuing Bank until such LC Exposure is cash collateralized and/or reallocated;

  
 42 

 (d) so long as any Lender is a Defaulting Lender, the Issuing Bank shall not be required to
issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral that will be provided by the Borrower in accordance with
Section 4.05(c), and participating interests in any such newly issued or increased Letter of Credit shall be allocated among non-Defaulting Lenders in a manner consistent with Section 4.05(c)(i) (and Defaulting Lenders shall not
participate therein); and 
 (e) any amount payable to such Defaulting Lender hereunder (whether on account of principal,
interest, fees or otherwise and including any amount that would otherwise be payable to such Defaulting Lender) shall, to the extent permitted by applicable law, in lieu of being distributed to such Defaulting Lender, be retained by the
Administrative Agent in a segregated account and, subject to any applicable requirements of law, be applied at such time or times as may be determined by the Administrative Agent (i) first, to the payment of any amounts owing by such
Defaulting Lender to the Administrative Agent hereunder; (ii) second, to the payment of any amounts owing by such Defaulting Lender to the Issuing Bank hereunder, (iii) third, to the funding of any Loan or the funding or cash
collateralization of any participating interest in any Letter of Credit in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, (iv) fourth, if so determined by the Administrative
Agent and the Borrower, held in such account as cash collateral for future funding obligations of the Defaulting Lender under this Agreement, (v) fifth, pro rata, to the payment of any amounts owing to the Borrower or the Lenders as a
result of any judgment of a court of competent jurisdiction obtained by the Borrower or any Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement and (vi) sixth,
to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if such payment is (x) a prepayment of the principal amount of any Loans or reimbursement obligations in respect of Letter of Credit
Disbursements of which a Defaulting Lender has funded its participation obligations and (y) made at a time when the conditions set forth in Section 4.02 are satisfied, such payment shall be applied solely to prepay the Loans of, and
reimbursement obligations owed to, all non-Defaulting Lenders pro rata prior to being applied to the prepayment of any Loans, or reimbursements obligations owed to, any Defaulting Lender. 

ARTICLE V 

INCREASED COSTS; BREAK FUNDING PAYMENTS; TAXES; ILLEGALITY 
 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 

  
 43 

 (ii) impose on any Lender or the London interbank market any other condition
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, but not
including Excluded Taxes, Indemnified Taxes or Other Taxes), 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 or the Issuing Bank determines that any Change in Law regarding capital requirements has
or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this Agreement or the
Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding
company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with respect to capital
adequacy), then from time to time the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s
holding company for any such reduction suffered. 
 (c) Certificates. A certificate of a Lender or the Issuing Bank
setting forth in reasonable detail the basis for, and a calculation of, the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in Section 5.01(a) or (b) shall
be delivered to the Borrower and shall be presumptively correct. Within 10 days after receipt thereof, the Borrower shall either (i) pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate, or
(ii) notify such payee in writing that the Borrower disputes the amount shown as due. If, after receiving such written notice, such payee disagrees with the Borrower as to the amount owed, the Borrower and such payee will meet in good faith to
discuss the basis for, and calculation of, the amount, and the Borrower’s basis for disputing such amount. If, after an additional 10 days following such good faith meeting, the Borrower and payee are unable to agree upon the amount owed, both
parties will submit to binding arbitration to resolve the dispute as to the amount owed. 
 (d) Effect of Failure or Delay in
Requesting Compensation. Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such
compensation; provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section 5.01 for any increased costs or reductions incurred more than 180 days prior to the date that such Lender
or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further
that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof. 

  
 44 

 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, (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 5.04(a), then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such
event (exclusive of any lost profits or opportunity costs). 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 10 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
(i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 5.03(a)), the Administrative Agent, Lender or Issuing Bank (as
the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower or such Guarantor shall make such deductions and (iii) 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. 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, each Lender and the Issuing Bank,
within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as 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, 

  
 45 

 
whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority; provided that the Borrower shall not be required to
indemnify the Administrative Agent, any Lender or the Issuing Bank for any amounts under this Section 5.03(c) to the extent that such Person fails to notify the Borrower of its intent to make a claim for indemnification under this
Section 5.03(c) within 180 days after a claim is asserted against such Person by the relevant Governmental Authority. A certificate of the Administrative Agent, a Lender or the Issuing Bank 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) Foreign Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the
jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at
the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate.

 (f) If a payment made to a Lender or Issuing Bank under this Agreement or any other Loan Document would be subject to U.S.
Federal withholding of Taxes 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 or Issuing
Bank 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 either 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 either the Borrower or the Administrative Agent, as applicable, as may be necessary for either the Borrower or the
Administrative Agent, as applicable, to comply with its obligations under FATCA, to determine that such Lender or Issuing Bank has complied with such Lender’s or Issuing Bank’s obligations under FATCA or to determine the amount to deduct
and withhold from such payment. 
 (g) Tax Refunds. If the Administrative Agent or a 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 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 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, 

  
 46 

 
upon the request of the Administrative Agent or such Lender, shall 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(g) 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. 

Section 5.04. Mitigation Obligations; Replacement of Lenders. 

(a) 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 (i) would eliminate or reduce amounts payable
pursuant to Section 5.01 or Section 5.03, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby
agrees to pay all reasonable costs and expenses incurred by any Lender solely as a result of any such designation or assignment. 
 (b) Replacement of Lenders. If (i) any Lender requests compensation under Section 5.01, (ii) 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, (iii) any Lender becomes a Defaulting Lender, (iv) any Lender has asserted that any adoption or change of the type described in Section 5.05 has occurred, or
(v) any Lender fails to approve an amendment, waiver or other modification to this Agreement and at least the Required Lenders have approved such amendment, waiver or other modification, or (vi) any Lender fails to approve an increase,
decrease or reaffirmation of the Borrowing Base and at least the Required Lenders have approved such increase, decrease or reaffirmation, 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(a)), 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) if such assignee is not a Lender 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 and participations in LC Disbursements, accrued interest thereon, accrued fees and all other
amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a
claim for compensation under Section 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. A Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. 

  
 47 

 Section 5.05. 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.

filing with, or any other action by, any Governmental Authority or any other third Person (including shareholders or any class of directors, whether interested or disinterested, of the Borrower or any other 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) filings with, and approvals from, the SEC, and approval of the noteholders and the shareholders of the Borrower that will have been obtained prior to the date of the initial funding in connection with the Reorganization,

 (b) Neither the Borrower nor any 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 under any indenture, note, credit agreement or instrument pursuant to which any Material Indebtedness is outstanding or by which the Borrower or any Subsidiary or any of their Properties is bound. 

(c) No Default has occurred and is continuing. 
 Section 7.08. Investment Company Act. Neither the Borrower nor any Subsidiary is an “investment company” within the meaning of, or subject to regulation under, the Investment Company

applicable, the Code regarding each Plan. 
 (b) Each Plan is, and has been, established and maintained in compliance with its

imposition on the Borrower, any Subsidiary or any ERISA Affiliate (whether directly or indirectly) of (i) either a civil penalty assessed pursuant to subsections (c), (i), (l) or (m) 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) Full payment when due has been made of all amounts which the Borrower, the Subsidiaries or any ERISA Affiliate is required under the

other Loan Document (as modified or supplemented by other information so furnished), when furnished, contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not materially misleading (other than omissions that pertain to matters of a general economic nature or matters of public knowledge that generally affect any of the industry segments of the Borrower or its
Subsidiaries); provided that, with respect to projected financial information, prospect information, geological and geophysical data and engineering projections the Borrower represents only that such information was prepared in good faith based upon
assumptions believed to be reasonable at the time, recognizing that there are industry-wide risks normally associated with the types of business conducted by the Borrower and its Subsidiaries. There are no statements or conclusions in any Reserve
Report which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein, it being understood that projections concerning volumes attributable to the Oil and Gas
Properties of the Borrower and the Subsidiaries and production and cost estimates contained in each Reserve Report are necessarily based upon professional opinions, estimates and projections and that the Borrower and the Subsidiaries do not warrant
that such opinions, estimates and projections will ultimately prove to have been accurate. 

  
 56 

 Section 7.12. Insurance. The Borrower has, and has caused all of its
Subsidiaries to have, (a) all insurance policies sufficient for the compliance by each of them with all material Governmental Requirements 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 its 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 7.13. Restriction on Liens. Neither the Borrower nor any of the Subsidiaries is a party to any material agreement or
arrangement (other than the Senior Indenture, Debt and Capital Leases creating Liens permitted by Section 9.03(c), but then only on the Property securing such Debt or subject to such Capital Lease, any accessions thereto and proceeds thereof),
or, on the Effective Date, 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
Secured Obligations and the Loan Documents. 
 Section 7.14. Subsidiaries; Foreign Operations. Except as set forth
on Schedule 7.14 or as disclosed in writing to the Administrative Agent (which shall promptly furnish a copy to the Lenders), which shall be a supplement to Schedule 7.14, the Borrower has no Subsidiaries and the Borrower has no Foreign Subsidiaries
and no Subsidiary owns any Oil and Gas Properties not located within the geographic boundaries of the United States of America. Each Subsidiary on Schedule 7.14 is a Wholly-Owned Subsidiary. 

Section 7.15. 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 its jurisdiction of organization is Dune Energy, Inc.; and the organizational identification number of the Borrower in its jurisdiction of organization is 2969625 (or, in each case, as set forth in a

Section 12.01 (or as set forth in a notice delivered pursuant to Section 8.01(m) and Section 12.01(c)). Each Subsidiary’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 7.14 (or as set forth in a notice delivered pursuant to
Section 8.01(m)). 

  
 57 

 Section 7.16. Properties; Titles, Etc. Except as could not reasonably be
expected to have a Material Adverse Effect: 
 (a) Each of the Borrower and the Subsidiaries has good and defensible title to
the Oil and Gas Properties evaluated in the most recently delivered Reserve Report and good title to all its personal Properties that are necessary to permit the Borrower and the Subsidiaries to conduct their business in all material respects in the
same manner as its business has been conducted prior to the date hereof, and in each case, free and clear of all Liens except Liens permitted by Section 9.03. After giving full effect to the Excepted Liens, the Borrower or the Subsidiary
specified as the owner owns the net interests in production attributable to the Hydrocarbon Interests as reflected in the most recently delivered Reserve Report, and the ownership of such Properties shall not obligate the Borrower or such Subsidiary
to bear the costs and expenses relating to the maintenance, development and operations of each such Property in an amount materially in excess of the working interest of each Property set forth in the most recently delivered Reserve Report that is
not offset by a corresponding proportionate increase in the Borrower’s or such Subsidiary’s net revenue interest in such Property; provided that the Borrower or any Subsidiary shall have the right to bear costs disproportionate to the
Borrower’s or such Subsidiary’s working interest with respect to any Hydrocarbon Interest for a period of time in order to earn an interest in such Hydrocarbon Interest from a third party as evidenced by written agreement. 

(b) All material leases and agreements necessary for the conduct of the business of the Borrower and the 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. 

(c) The rights and Properties presently owned, leased or licensed by the Borrower and the Subsidiaries including, without limitation, all
easements and rights of way, include all rights and Properties necessary to permit the Borrower and the Subsidiaries to conduct their business in all material respects in the same manner as its business has been conducted prior to the date hereof.

 (d) All of the Properties of the Borrower and the Subsidiaries which are reasonably necessary for the operation of their
businesses are in good working condition (normal wear and tear excepted) and are maintained in accordance with prudent business standards. 
 (e) The Borrower and each 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 Subsidiary does not infringe upon the rights of any other Person. The Borrower and its 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. 
 Section 7.17. 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 Borrower and its Subsidiaries have been maintained,
operated and developed in a good and workmanlike manner and in conformity with all 

  
 58 

 
Governmental Requirements 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 the Oil and Gas Properties of the Borrower and its Subsidiaries. Specifically in connection with the foregoing, except for those as could not be reasonably expected to have a Material Adverse Effect, (i) no Oil and Gas
Property of the Borrower or any Subsidiary 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 (ii) none of the wells comprising a part of the Oil and Gas Properties (or Properties unitized therewith) of the Borrower or any Subsidiary is deviated from the vertical more than the maximum permitted by Governmental
Requirements, and such wells are, in fact, bottomed under and are producing from, and the well bores are wholly within, the Oil and Gas Properties (or in the case of wells located on Properties unitized therewith, such unitized Properties) of the
Borrower or such Subsidiary. All pipelines, wells, gas processing plants, platforms and other material improvements, fixtures and equipment owned in whole or in part by the Borrower or any of its Subsidiaries 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 the Borrower or any of its Subsidiaries, in a manner consistent with the Borrower’s or its
Subsidiaries’ past practices (other than those the failure of which to maintain in accordance with this Section 7.17 could not reasonably be expected to have a Material Adverse Effect). 

Section 7.18. Gas Imbalances, Prepayments. Except as set forth on Schedule 7.18 or on the most recent certificate delivered
pursuant to Section 8.12(c), on a net basis there are no gas imbalances, take or pay or other prepayments which would require the Borrower or any of its Subsidiaries to deliver Hydrocarbons produced from their Oil and Gas Properties at some
future time without then or thereafter receiving full payment therefor exceeding one-fourth of a bcf of gas (on an mcf equivalent basis) in the aggregate. 
 Section 7.19. Marketing of Production. Except for contracts listed and in effect on the date hereof on Schedule 7.19, and thereafter either disclosed in writing to the Administrative Agent or
included in the most recently delivered Reserve Report (with respect to all of which contracts the Borrower represents that it or its 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), no material agreements exist which are not cancelable on 60 days notice or less without penalty or
detriment for the sale of production from the Borrower’s or its 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 (6) months from the date hereof. 
 Section 7.20. Swap Agreements. Schedule 7.20, as of the date hereof, and after the date hereof, 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 and each Subsidiary, the material terms thereof (including the type, term, effective date, termination date and notional amounts or volumes), the net mark to market value
thereof, all credit support agreements relating thereto (including any margin required or supplied) and the counterparty to each such agreement. 

  
 59 

 Section 7.21. Use of Loans and Letters of Credit. The Borrower and its
Subsidiaries are not 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). 
 Section 7.22. Solvency. After giving effect to the transactions contemplated
hereby, (a) the aggregate assets (after giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement), at a fair valuation, of the Borrower and the Guarantors, taken as a whole,
will exceed the aggregate Debt of the Borrower and the Guarantors on a consolidated basis, as the Debt becomes absolute and matures, (b) the Borrower and the Guarantors on a consolidated basis will not have incurred or intended to incur, and
believe that they will not have incurred Debt beyond their ability to pay such Debt (after taking into account the timing and amounts of cash to be received by each of the Borrower and the Guarantors and the amounts to be payable on or in respect of
its liabilities, and giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement) as such Debt becomes absolute and matures and (c) each of the Borrower and the Guarantors will
not have (and will have no reason to believe that it will have thereafter) unreasonably small capital for the conduct of its business. 
 Section 7.23. Reorganization. The copies of the Reorganization Documents previously delivered by the Borrower to the Administrative Agent are complete and have not been amended or modified in
any manner, other than pursuant to amendments or modifications previously delivered to the Administrative Agent. 

Section 7.24. Foreign Corrupt Practices. Neither the Borrower nor any of its Subsidiaries, nor any director, officer, agent,
employee of the Borrower or any of its Subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a material violation by such Persons of the Foreign Corrupt Practices Act, including without limitation, making use
of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving
of anything of value to any “foreign official” (as such term is defined in the Foreign Corrupt Practices Act) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the Foreign
Corrupt Practices Act; and, the Borrower and its Subsidiaries have conducted their business in material compliance with the Foreign Corrupt Practices Act and have instituted and maintain policies and procedures designed to ensure, and which are
reasonably expected to continue to ensure, continued compliance therewith. 
 Section 7.25. Money Laundering. The
operations of the Borrower and its Subsidiaries are and have been conducted at all times in material compliance with applicable financial recordkeeping and reporting requirements of the Money Laundering Laws, and no action, suit or proceeding by or
before any court or governmental agency, authority or body or any arbitrator involving the Borrower or any of its Subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Borrower, threatened. 

  
 60 

 Section 7.26. OFAC. Neither the Borrower nor any of its Subsidiaries, nor any
director, officer, agent, employee or Affiliate of the Borrower or any of its Subsidiaries is currently subject to any material U.S. sanctions administered by the Office of Foreign Asset Control, and the Borrower will not directly or indirectly use
the proceeds from the Loans or lend, contribute or otherwise make available such proceeds to any Subsidiary, joint venture partner or other Person, for the purpose of financing the activities of any Person currently subject to any U.S. sanctions

 63 

 Documents required to be delivered pursuant to this Article VIII shall be delivered in accordance with the
terms of this Agreement either as a hard-copy or electronically, at the Borrower’s discretion. If the Borrower delivers hard-copies of such certificates, statements or other reports, then the Borrower shall so deliver to the Administrative

investigation or arbitration (whether or not previously disclosed to the Lenders) that, in either case, if adversely determined, could reasonably be expected to result in a Material Adverse Effect; and 

(c) any other development that results in, or could reasonably be expected to result in, a Material Adverse Effect.

business and maintain, if necessary, its qualification to do business in each other jurisdiction in which its Oil and Gas Properties are located or the ownership of its Properties requires such qualification, except where the failure to do any of
the foregoing as to clause (ii) could not reasonably be expected to have a Material Adverse Effect; provided that the foregoing shall not prohibit any merger, consolidation, liquidation, dissolution, sale or other disposition permitted under
Section 9.11. 
 Section 8.04. Payment of Obligations. The Borrower will, and will cause each Subsidiary to,
pay its obligations, including Tax liabilities of the Borrower and all of its Subsidiaries before the same shall become delinquent or in default, except where (a) the validity or amount thereof is being contested in good faith by appropriate
proceedings, (b) the Borrower or such Subsidiary has set aside on its books adequate reserves with respect thereto in accordance with GAAP and (c) the failure to make payment pending such contest could not reasonably be expected to result

Section 8.05. Performance of Obligations under Loan Documents. The Borrower will pay the Notes according to the terms
thereof, and the Borrower will, and will cause each Subsidiary to, do and perform every act and discharge all of the obligations to be performed and discharged by them under the Loan Documents, including, without limitation, this Agreement, at the

tear excepted) all of its material Oil and Gas Properties described in the most recent Reserve Report, including, without limitation, all equipment, machinery and facilities. 
 (c) promptly pay and discharge, or make reasonable and customary efforts to cause to be paid and discharged, all delay rentals, royalties, expenses and obligations accruing under the leases or other

 65 

 (d) promptly perform or make reasonable and customary efforts to cause to be performed, in
accordance with industry standards, the obligations required by each and all of the assignments, deeds, leases, sub-leases, contracts and agreements affecting its interests in its material Oil and Gas Properties, except where the failure to do so
could not reasonably be expected to have a Material Adverse Effect. 
 (e) to the extent the Borrower is not the operator of any
Property, the Borrower shall use commercially reasonable efforts to cause the operator to comply with this Section 8.06. 

Section 8.07. Insurance. The Borrower will, and will cause each Subsidiary to, maintain, with financially sound and reputable
insurance companies, insurance in such amounts and against such risks as are customarily maintained by companies engaged in the same or similar businesses operating in the same or similar locations. The loss payable clauses or provisions in said
insurance policy or policies insuring any of the collateral for the Loans shall be endorsed in favor of the Administrative Agent as its interests may appear and such policies shall name the Administrative Agent and the Lenders as “additional
insureds” and provide that the insurer will endeavor to give at least 30 days prior notice of any cancellation to the Administrative Agent. 
 Section 8.08. Books and Records; Inspection Rights. The Borrower will, and will cause each Subsidiary to, keep proper books of record and account in which full, true and correct entries are
made of all dealings and transactions in relation to its business and activities. The Borrower will, and will cause each Subsidiary to, permit any representatives designated by the Administrative Agent or any Lender, upon reasonable prior notice, to
visit and inspect its Properties, to examine and make extracts from its books and records, and to discuss its affairs, finances and condition with its officers and independent accountants, all at such reasonable times and as often as reasonably
requested. The Borrower shall bear the cost of not more than one (1) such inspection and examination during any 12-month period unless a Default or Event of Default then exists, in which event the Borrower shall bear such cost. 

Section 8.09. Compliance with Laws. The Borrower will, and will cause each Subsidiary to, comply with all laws, rules,
regulations and orders of any Governmental Authority applicable to it or its Property, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. 

Section 8.10. Environmental Matters. 
 (a) The Borrower shall at its sole expense: (i) comply, and shall cause its Properties and operations and each Subsidiary and each Subsidiary’s Properties and operations to comply, with all
applicable Environmental Laws, the breach of which could be reasonably expected to have a Material Adverse Effect; (ii) not Release or threaten to Release, and shall cause each Subsidiary not to Release or threaten to Release, any Hazardous
Material on, under, about or from any of the Borrower’s or its Subsidiaries’ Properties or any other property offsite the Property to the extent caused by the Borrower’s or any of its Subsidiaries’ operations except in

  
 66 

 
compliance with applicable Environmental Laws, the Release or threatened Release of which could reasonably be expected to have a Material Adverse Effect; (iii) timely obtain or file, and
shall cause each Subsidiary to timely obtain or file, all Environmental Permits, if any, required under applicable Environmental Laws to be obtained or filed in connection with the operation or use of the Borrower’s or its Subsidiaries’
Properties, which failure to obtain or file could reasonably be expected to have a Material Adverse Effect; (iv) promptly commence and diligently prosecute to completion, and shall cause each Subsidiary to promptly commence and diligently
prosecute to completion, any assessment, evaluation, investigation, monitoring, containment, cleanup, removal, repair, restoration, remediation or other remedial obligations (collectively, the “Remedial Work”) in the event any
Remedial Work is required or reasonably necessary under applicable Environmental Laws because of or in connection with the actual or suspected past, present or future Release or threatened Release of any Hazardous Material on, under, about or from
any of the Borrower’s or its Subsidiaries’ Properties, which failure to commence and diligently prosecute to completion would reasonably be expected to have a Material Adverse Effect; (v) conduct, and cause its Subsidiaries to
conduct, their respective operations and businesses in a manner that will not expose any Property or Person to Hazardous Materials that would reasonably be expected to form the basis for a claim for damages or compensation that would reasonably be

Section 8.10(a) are timely and fully satisfied, which failure to establish and implement could reasonably be expected to have a Material Adverse Effect. 
 (b) The Borrower will promptly, but in no event later than five days after obtaining knowledge of the occurrence of a triggering event, notify the Administrative Agent and the Lenders in writing of any
threatened action, investigation or inquiry by any Governmental Authority or any threatened demand or lawsuit by any Person against the Borrower or its Subsidiaries or their Properties in connection with any Environmental Laws if the Borrower could

Properties. 
 (d) To the extent the Borrower or a Subsidiary is not the operator of any Property, none of the Borrower and its
Subsidiaries shall be obligated to directly perform any undertakings contemplated by the covenants and agreements contained in this Section 8.10 which are performable only by such operators and are beyond the control of the Borrower or any of
its Subsidiaries. Notwithstanding the above and except to the extent that the failure to do so could not reasonably be expected to have a Material Adverse Effect, the Borrower shall, and shall cause its Subsidiaries to, use commercially reasonable
efforts to cause the operator to comply with this Section 8.10.

 Section 8.11. Further Assurances. 

(a) The Borrower at its sole expense will, and will cause each Subsidiary to, promptly execute and deliver to the Administrative Agent
all such other documents, agreements and instruments reasonably requested by the Administrative Agent to comply with, cure any defects or accomplish the conditions precedent, covenants and agreements of the Borrower or any Subsidiary, as the case
may be, in the Loan Documents, including the Notes, or to further evidence and more fully describe the collateral intended as security for the Secured Obligations, or to correct any omissions in this Agreement or the Security Instruments, or to
state more fully the obligations secured therein, or to perfect, protect or preserve any Liens created pursuant to this Agreement or any of the Security Instruments or the priority thereof, or to make any recordings, file any notices or obtain any
consents, all as may be reasonably necessary or appropriate, in the sole discretion of the Administrative Agent, in connection therewith. 
 (b) The Borrower hereby authorizes the Administrative Agent to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Mortgaged Property without
the signature of the Borrower or any other Guarantor where permitted by law. A carbon, photographic or other reproduction of the Security Instruments or any financing statement covering the Mortgaged Property or any part thereof shall be sufficient
as a financing statement where permitted by law. 
 Section 8.12. Reserve Reports. 

(a) On or before March 1st and September 1st of each year, commencing March 1st, 2012, the Borrower shall furnish to the Administrative Agent and
the Lenders a Reserve Report evaluating the Oil and Gas Properties of the Borrower and its Subsidiaries as of the immediately preceding December 31 and June 30. The Reserve Report as of December 31 of each year shall be prepared by or
under the supervision of the chief engineer of the Borrower who shall certify such Reserve Report to be true and accurate and to have been prepared in accordance with the procedures used in the immediately preceding Reserve Report, if applicable,
prepared by one or more Approved Petroleum Engineers and the June 30 Reserve Report of each year shall be prepared by one or more Approved Petroleum Engineers. It is understood that projections concerning volumes attributable to the Oil and Gas
Properties and production and cost estimates contained in each Reserve Report are necessarily based upon professional opinions, estimates and projections and that the Borrower and the Subsidiaries do not warrant that such opinions, estimates and
projections will ultimately prove to have been accurate. 
 (b) In the event of an Interim Redetermination, the Borrower shall
furnish to the Administrative Agent and the Lenders a Reserve Report prepared by or under the supervision of the chief engineer of the Borrower who shall certify such Reserve Report to be true and accurate and to have been prepared in accordance
with the procedures used in the immediately preceding December 31 Reserve Report. For any Interim Redetermination requested by the Administrative Agent or the Borrower pursuant to Section 2.07(b), the Borrower shall provide such Reserve
Report with an “as of” date as required by the Administrative Agent as soon as possible, but in any event no later than thirty (30) days following the receipt of such request. 

  
 68 

 Section 8.13. Title Information. 

(a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 8.12(a), the
Borrower will deliver title information in form and substance acceptable to the Administrative Agent covering enough of the Oil and Gas Properties evaluated by such Reserve Report that were not included in the immediately preceding Reserve Report,
so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 85% of the total value of the Oil and Gas Properties evaluated by such
Reserve Report. 
 (b) If the Borrower has provided title information for additional Properties under Section 8.13(a), the
Borrower shall, within 60 days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as
to priority) which are not permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions except for Excepted Liens (other than Excepted Liens described in clauses
(e), (g) and (h) of such definition) having an equivalent value or (iii) deliver title information in form and substance acceptable to the Administrative Agent so that the Administrative Agent shall have received, together with title
information previously delivered to the Administrative Agent, satisfactory title information on at least 85% of the value of the Oil and Gas Properties evaluated by such Reserve Report. 

(c) If the Borrower is unable to cure any title defect requested by the Administrative Agent or the Lenders to be cured within the 60-day
period or the Borrower does not comply with the requirements to provide acceptable title information covering 85% of the value of the Oil and Gas Properties evaluated in the most recent Reserve Report, such default shall not be a Default, but
instead the Administrative Agent and/or the Majority Lenders shall have the right to exercise the following remedy in their sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future
exercise of the remedy by the Administrative Agent or the Lenders. To the extent that the Administrative Agent or the Majority Lenders are not satisfied with title to any Mortgaged Property after the 60-day period has elapsed, such unacceptable
Mortgaged Property shall not count towards the 85% requirement, and the Administrative Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Required
Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 80% of the value of the Oil and Gas Properties. This new Borrowing Base shall become effective immediately after receipt of such
notice. 
 Section 8.14. Additional Collateral; Additional Guarantors. 

(a) In connection with each redetermination of the Borrowing Base, the Borrower shall review the Reserve Report and the list of current
Mortgaged Properties (as described in Section 8.12(c)(vi)) to ascertain whether the Mortgaged Properties represent at least (i) 85% of the total proved value and (ii) 90% of the total proved value attributable to proved developed
producing of the Oil and Gas Properties evaluated in the most recently completed Reserve Report after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the Mortgaged Properties do
not represent at least (i) 85% of such total value and (ii) 90% of the proved developed producing value, then the Borrower shall, and 

  
 69 

 
shall cause its Subsidiaries to, grant, within thirty (30) days of delivery of the certificate required under Section 8.12(c), to the Administrative Agent as security for the Secured
Obligations a first-priority Lien interest (provided that Excepted Liens of the type described in clauses (a) to (d) and (f) of the definition thereof may exist, but subject to the provisos at the end of such definition, and Liens
permitted by Section 9.03(e) may exist) on additional Oil and Gas Properties not already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent not less than the minimum set
forth above. All such Liens will be created and perfected by and in accordance with the provisions of deeds of trust, security agreements and financing statements or other Security Instruments, all in form and substance reasonably satisfactory to
the Administrative Agent and in sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes. In order to comply with the foregoing, if any Subsidiary places a Lien on its Oil and Gas Properties and such
Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 8.14(b). 
 (b) In the event that
the Borrower creates or acquires any Domestic Subsidiary, the Borrower shall promptly cause such Subsidiary to guarantee the Secured Obligations pursuant to the Guaranty Agreement. In connection with any such guaranty, the Borrower shall, or shall
cause such Subsidiary to, (A) execute and deliver a supplement to the Guaranty Agreement executed by such Subsidiary, (B) pledge all of the Equity Interests of such new Subsidiary (including, without limitation, delivery of original stock
certificates evidencing the Equity Interests of such Subsidiary, if any, together with an appropriate undated stock powers for each certificate duly executed in blank by the registered owner thereof) and (C) execute and deliver such other
additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent. 

(c) At any time during the continuation of an Event of Default, if required by the Administrative Agent, the Borrower shall, and shall
cause each of its Domestic Subsidiaries to grant to the Administrative Agent a Lien to secure the Secured Obligations on all other Oil and Gas Properties having probable and possible reserves and other acreage positions, except those assets as to
which the Administrative Agent shall determine in its reasonable discretion that the cost of obtaining a Lien or other security interest therein is excessive in relation to the value of the security to be afforded thereby. 

Section 8.15. ERISA Compliance. The Borrower will promptly furnish and will cause the Subsidiaries and any ERISA Affiliate to
promptly furnish to the Administrative Agent immediately upon becoming aware of the occurrence of any non-exempt “prohibited transaction,” as described in section 406 of ERISA or in section 4975 of the Code, in connection with any Plan or
any trust created thereunder, a written notice signed by the President or the principal Financial Officer, the Subsidiary or the ERISA Affiliate, as the case may be, specifying the nature thereof, what action the Borrower, the Subsidiary or the
ERISA Affiliate is taking or proposes to take with respect thereto, and, when known, any action taken or proposed by the Internal Revenue Service or the Department of Labor with respect thereto. 

  
 70 

 Section 8.16. Swap Agreements. Within three (3) Business Days after
purchase by the Borrower, the Administrative Agent shall have received evidence that the Borrower, for each year during the period commencing not later than fifteen (15) Business Days after the Effective Date and ending on December 2014, has
purchased one or more commodity price floors or collars with one or more Approved Counterparties and which have (a) a floor strike price of not less than $85 per barrel in respect of crude oil (NYMEX/WTI basis adjusted equivalent) for calendar
years 2012-2014 on notional volumes representing not less than 37.5% of projected production from proved developed producing Oil and Gas Properties, (b) a floor strike price of not less than $3.00/mmbtu for calendar year 2012, $3.50/mmbtu for
calendar year 2013 and $3.75/mmbtu for calendar year 2014 in respect of natural gas (NYMEX/Henry Hub basis adjusted equivalent) on notional volumes representing not less than 60% of projected production from proved developed producing Oil and Gas
Properties, and (c) a swap price of $94 per barrel for calendar year 2012, $92 per barrel for calendar year 2013 and $90 per barrel for calendar year 2014 in respect of crude oil (NYMEX/WTI basis adjusted equivalent) on notional volumes
representing not less than 37.5% of projected production from proved developed producing Oil and Gas Properties, or in each case for notional volumes for equivalent or greater value, as determined by the Administrative Agent in its reasonable
discretion, and in each case as determined by reference to the Initial Reserve Reports. The Borrower shall maintain the hedge position established by the Swap Agreements required under this Section 8.16 during the period specified therein and
shall neither assign, terminate or unwind any such Swap Agreements nor sell any Swap Agreements without prior notice to the Administrative Agent and the Lenders and an adjustment to the Borrowing Base as contemplated by Section 2.07(e).

(a) any Subsidiary may participate in a consolidation with the Borrower (provided that the Borrower shall be the continuing or surviving

 (a) sales of Hydrocarbons in the ordinary course of business and sales of obsolete, worn-out or surplus equipment in the ordinary course of business; 

(b) so long as no Event of Default then exists or would result from such action, farmouts and leases of any of the Oil and Gas Properties
not included in the determination of the then current Borrowing Base, so long as such farmouts and leases are in the ordinary course of business and on terms customary in the industry; 

(c) disposition of any Investments permitted under Section 9.05(c) through 9.05(f) and 9.05(j); 

(d) dispositions (including farmouts) of any Oil and Gas Properties included in the determination of the then current Borrowing Base or
any interest therein or Equity Interests of any Subsidiary owning Oil and Gas Properties included in the determination of the then current Borrowing Base for cash consideration of not less than fair market value, provided that (1) no
Event of Default has occurred and is continuing at the date of such disposition and no Event of Default would result therefrom and (2) if the aggregate fair market value (calculated at the time of such disposition) of all such Oil and Gas
Properties disposed of, together with the aggregate Swap Agreement PV of all commodity hedge positions terminated and/or offset, in each case, since the last Scheduled Redetermination Date exceeds 5% of the then-effective Borrowing Base, then no

of such Oil and Gas Properties so disposed;

extent such net cash proceeds are not sufficient to eliminate such Borrowing Base Deficiency); provided that the Borrower will not be required to so apply the net cash proceeds from the sale or transfer of the property or assets securing any secured
Debt permitted by Section 9.03(c) or (d) to the extent such net cash proceeds are applied to discharge such Debt.

comparable arm’s length transaction with a Person not an Affiliate, (b) reasonable and customary fees paid to members of the board of directors (or similar governing body) of the Borrower and its Subsidiaries, (c) compensation
arrangements for officers and other employees of the Borrower and its Subsidiaries entered into in the ordinary course of business, (d) transactions permitted by Section 9.04(a), and (e) transactions set forth on Schedule 9.13.

making distributions to the Borrower or any Guarantor, or which requires the consent of or notice to other Persons in connection therewith; provided, however, that the preceding restrictions will not apply to encumbrances or restrictions arising
under or by reason of (i) this Agreement, the Security Instruments or the Senior Indenture, (ii) Liens permitted by Section 9.03(c) (but only to the extent related to the Property on which such Liens were created), (iii) any

Agreement is executed, 80% of the reasonably anticipated projected production from proved, developed, producing Oil and Gas Properties for each month during the period during which such Swap Agreement is in effect for each of crude oil, natural gas
liquids and natural gas, calculated separately, and (b) Swap Agreements in respect of interest rates with an Approved Counterparty, Swap Agreements effectively converting interest rates from floating to fixed, the notional amounts of which
(when aggregated with all other Swap Agreements of the Borrower and its Subsidiaries then in effect effectively converting interest rates from floating to fixed) do not exceed 75% of the then outstanding principal amount of the Borrower’s Debt
for borrowed money which bears interest at a floating rate. 
 Section 9.18. Reorganization Documents. The Borrower
will not, and will not permit any of its Subsidiaries to, amend, modify or supplement any of the Reorganization Documents if the effect thereof could reasonably be expected to have a Material Adverse Effect (and provided that the Borrower promptly
furnishes to the Administrative Agent a copy of such amendment, modification or supplement).

agreements, unitization agreements or other similar contracts that are usual and customary in the oil and gas business and (iii) other contracts for the purchase and/or sale of Hydrocarbons of third parties (A) which have generally
offsetting provisions (i.e., corresponding pricing mechanics, delivery dates and points and volumes) such that no “position” is taken and (B) for which appropriate credit support has been taken to alleviate the material credit
risks of the counterparty thereto.

 ARTICLE XI 
 THE AGENTS 
 Section 11.01. Appointment; Powers. Each of the
Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the
terms hereof and the other Loan Documents, together with such actions and powers as are reasonably incidental thereto. 

Section 11.02. Duties and Obligations of Administrative Agent. The Administrative Agent shall not have any duties or
obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default
has occurred and is continuing (the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under
agency doctrine of any applicable law; rather, 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), (b) the Administrative
Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except as provided in Section 11.03, and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to
disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any
capacity. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and shall not be responsible for or have any duty to
ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or under
any other Loan Document or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or in any other Loan Document, (iv) the validity,
enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, (v) the satisfaction of any condition set forth in Article VI or elsewhere herein, other than to confirm
receipt of items expressly required to be delivered to the Administrative Agent or as to those conditions precedent expressly required to be to the Administrative Agent’s satisfaction, (vi) the existence, value, perfection or priority of
any collateral security or the financial or other condition of the Borrower and its Subsidiaries or any other obligor or guarantor, or (vii) any failure by the Borrower or any other Person (other than itself) to perform any of its obligations
hereunder or under any other Loan Document or the performance or observance of any covenants, agreements or other terms or conditions set forth herein or therein. For purposes of determining compliance with the conditions specified in Article VI,
each Lender shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative
Agent shall have received written notice from such Lender prior to the Effective Date specifying its objection thereto. 

  
 83 

 Section 11.03. Action by Administrative Agent. The Administrative Agent shall
have no duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise in writing
as directed by the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) and in all cases the Administrative Agent shall be fully justified in failing or
refusing to act hereunder or under any other Loan Documents unless it shall (a) receive written instructions from the Majority Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under
the circumstances as provided in Section 12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or
continuing to take any such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, then the
Administrative Agent shall take such action with respect to such Default as shall be directed by the requisite Lenders in the written instructions (with indemnities) described in this Section 11.03, provided that, unless and until the
Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best
interests of the Lenders. In no event, however, shall the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, the Loan Documents or applicable law.
If a Default has occurred and is continuing, the Syndication Agent shall not have any obligation to perform any act in respect thereof. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the
request of the Majority Lenders or the Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02), and otherwise the Administrative Agent shall not be liable for any
action taken or not taken by it hereunder or under any other Loan Document or under any other document or instrument referred to or provided for herein or therein or in connection herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except
for its own gross negligence or willful misconduct. 
 Section 11.04. Reliance by Administrative Agent. The
Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed
or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon and each of the
Borrower, the Lenders and the Issuing Bank hereby waives the right to dispute the Administrative Agent’s record of such statement, except in the case of gross negligence or willful misconduct by the Administrative Agent. The Administrative
Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel,
accountants or experts. The Administrative Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof permitted hereunder shall have been filed
with the Administrative Agent. 

  
 84 

 Section 11.05. Subagents. The Administrative Agent may perform any and all its
duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through
their respective Related Parties. The exculpatory provisions of the preceding Sections of this Article XI shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their
respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. 
 Section 11.06. Resignation of Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this Section 11.06, the Administrative
Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such resignation, the Majority Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have
been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation of the retiring Agent, then the retiring Agent may, on behalf of the Lenders and the Issuing
Bank, appoint a successor Agent. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After
the Agent’s resignation hereunder, the provisions of this Article XI and Section 12.03 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or
omitted to be taken by any of them while it was acting as Agent. 
 Section 11.07. Agents as Lenders. Each bank
serving as an Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and such bank and its Affiliates may accept deposits from, lend money to
and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder. 
 Section 11.08. No Reliance. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and each other Loan Document to which it is a party. Each Lender also acknowledges that it will, independently and without
reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based
upon this Agreement, any other Loan Document, any related agreement or any document furnished hereunder or thereunder. The Agents shall not be required to keep themselves informed as to the performance or observance by the Borrower or any of its
Subsidiaries of this Agreement, the Loan Documents or any other document referred to or provided for herein or to inspect the Properties or books of the Borrower or its Subsidiaries. Except for notices, reports and other documents and information
expressly required to be furnished to the Lenders by the Administrative Agent hereunder, no Agent or the Arranger shall have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial
condition or business of the Borrower (or any of its Affiliates) which may come into the possession of such Agent or any of its Affiliates. In this regard, each 

  
 85 

 
Lender acknowledges that Simpson, Thacher & Bartlett L.L.P. is acting in this transaction as special counsel to the Administrative Agent only, except to the extent otherwise expressly
stated in any legal opinion or any Loan Document. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein. 

Section 11.09. Administrative Agent May File Proofs 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 of its Subsidiaries, 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 Secured Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the 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; 
 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 Secured Obligations 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 11.10. Authority of Administrative Agent to Release Collateral and Liens. Each Lender and the Issuing Bank hereby
authorizes the Administrative Agent to release any collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents. Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to execute and deliver to
the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination statements, assignments or other documents reasonably requested by the Borrower in connection with any sale or other disposition of Property to
the extent such sale or other disposition is permitted by the terms of Section 9.12 or is otherwise authorized by the terms of the Loan Documents. 

  
 86 

 Section 11.11. The Arranger and the Syndication Agent. The Arranger and the
Syndication Agent shall have no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than their duties, responsibilities and liabilities in their capacity as Lenders hereunder.

Section 12.02. Waivers; Amendments. 
 (a) No failure on the part of the Administrative Agent, any other Agent, the Issuing Bank 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, any other Agent, the Issuing Bank 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 the Borrower
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 or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any other Agent, any Lender or the Issuing Bank may have had
notice or knowledge of such Default at the time. 
 (b) 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 Borrower 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 Commitment or the Maximum Credit Amount of any Lender without the written consent of such Lender, (ii) increase the Borrowing Base without the written consent
of all of the Lenders, decrease or maintain the Borrowing Base without the consent of the Required Lenders, or modify Section 2.07 in any manner without the consent of each Lender (other than any Defaulting Lender); provided that a Scheduled
Redetermination may be postponed by the Required Lenders, (iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce any other Secured Obligations
hereunder or under any other Loan Document, without the written consent of each Lender directly affected thereby, (iv) postpone the scheduled date of payment or prepayment of the principal amount of any Loan or LC Disbursement, or any interest
thereon, or any fees payable hereunder, or any other Secured Obligations hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Maturity Date or the Termination Date without
the written consent of each Lender directly affected thereby, (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,
(vi) waive or amend Section 3.04(c), Section 6.01, Section 10.02(c) or Section 12.14 without the written consent of each Lender directly affected thereby (other than any Defaulting Lender), (vii) release any Guarantor
(except as set forth in the Guaranty Agreement), release all or substantially all of the collateral (other than as provided in Section 11.10), without the written 

  
 88 

 
consent of each Lender (other than any Defaulting Lender), (viii) change any of the provisions of this Section 12.02(b) or the definitions of “Required 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 (other than any Defaulting Lender), (ix) change Section 10.02(c) without the consent of each Person to whom a Secured Obligation is owed; provided further
that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent, or the Issuing Bank hereunder or under any other Loan Document without the prior written consent of the Administrative
Agent, such other Agent or the Issuing Bank, as the case may be, or (x) contractually subordinate the payment of all the Secured Obligations to any other Debt or contractually subordinate the priority of any of the Administrative Agent’s
Liens to the Liens securing any other Debt, in each case, without the written consent of each Lender (other than any Defaulting Lender). Notwithstanding the foregoing, any supplement to Schedule 7.14 (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 and
documented 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 invasive and
non-invasive assessments and 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 costs, expenses, Taxes, assessments and other charges incurred
by any 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, (iii) all reasonable
and documented out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder, (iv) all reasonable out-of-pocket expenses
incurred by any Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for any Agent, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with this
Agreement or any other Loan Document, including its rights under this Section 12.03, or in connection with the Loans made or Letters of Credit issued hereunder, including, without limitation, all such out-of-pocket expenses incurred during any
workout, restructuring or negotiations in respect of such Loans or Letters of Credit. 

  
 89 

 (b) THE BORROWER SHALL INDEMNIFY EACH AGENT, THE ARRANGER, THE ISSUING BANK AND EACH LENDER,
AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, AND DEFEND AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, PENALTIES, LIABILITIES AND
RELATED EXPENSES, INCLUDING THE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (i) THE EXECUTION OR DELIVERY OF 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 SUBSIDIARY TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, OR WITH ANY GOVERNMENTAL
REQUIREMENT, (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 DELIVERED IN CONNECTION
THEREWITH, (iv) ANY LOAN OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS THEREFROM, INCLUDING, WITHOUT LIMITATION, (A) ANY REFUSAL BY THE ISSUING BANK TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT IF THE DOCUMENTS PRESENTED IN
CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT, OR (B) THE PAYMENT OF A DRAWING UNDER ANY LETTER OF CREDIT NOTWITHSTANDING THE NON-COMPLIANCE, NON-DELIVERY OR OTHER IMPROPER PRESENTATION OF THE
DOCUMENTS PRESENTED IN CONNECTION THEREWITH, (v) ANY OTHER ASPECT OF THE LOAN DOCUMENTS, (vi) THE OPERATIONS OF THE BUSINESS OF THE BORROWER AND ITS SUBSIDIARIES BY THE BORROWER AND ITS SUBSIDIARIES, (vii) ANY ASSERTION THAT THE
LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED PURSUANT TO THE SECURITY INSTRUMENTS, (viii) ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY SUBSIDIARY OR ANY OF THEIR PROPERTIES OR OPERATIONS, INCLUDING, THE PRESENCE,
GENERATION, STORAGE, RELEASE, THREATENED RELEASE, USE, TRANSPORT, DISPOSAL, ARRANGEMENT OF DISPOSAL OR TREATMENT OF HAZARDOUS MATERIALS ON OR AT ANY OF THEIR PROPERTIES, (ix) THE BREACH OR NON-COMPLIANCE BY THE BORROWER OR ANY SUBSIDIARY WITH
ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY SUBSIDIARY, (x) THE PAST OWNERSHIP BY THE BORROWER OR ANY SUBSIDIARY OF ANY OF THEIR PROPERTIES OR PAST ACTIVITY ON ANY OF THEIR PROPERTIES WHICH, THOUGH LAWFUL AND FULLY PERMISSIBLE AT
THE TIME, COULD RESULT IN PRESENT LIABILITY, (xi) THE PRESENCE, USE, RELEASE, STORAGE, TREATMENT, DISPOSAL, GENERATION, THREATENED RELEASE, TRANSPORT, ARRANGEMENT FOR TRANSPORT OR ARRANGEMENT FOR DISPOSAL OF HAZARDOUS MATERIALS ON OR AT ANY OF
THE PROPERTIES OWNED OR OPERATED BY THE BORROWER OR ANY SUBSIDIARY OR ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF 

  
 90 

 
HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE BORROWER OR ANY OF ITS SUBSIDIARIES, (xii) ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE BORROWER OR ANY OF ITS
SUBSIDIARIES, OR (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 ARE DETERMINED BY A COURT
OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE, ANY MATERIAL BREACH BY ANY INDEMNITEE OF ITS OBLIGATIONS UNDER THE LOAN DOCUMENTS, OR ANY DISPUTE
SOLELY BETWEEN INDEMNITEES. 
 (c) To the extent that the Borrower fails to pay any amount required to be paid by it to any
Agent, the Arranger or the Issuing Bank under Section 12.03(a) or (b), each Lender severally agrees to pay to such Agent, the Arranger or the Issuing Bank, as the case may be, 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 such Agent, the Arranger or the Issuing Bank 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 Letter of Credit or the use of the proceeds thereof. 

(e) All amounts due under this Section 12.03 shall be payable not later than 10 Business Days after written demand therefor.

  
 91 

 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 (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written
consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this
Section 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 (including any Affiliate of the Issuing Bank
that issues any Letter of Credit), 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, the Issuing Bank and the Lenders) any legal
or equitable right, remedy or claim under or by reason of this Agreement. 
 (b) (i) Subject to the conditions set forth in
Section 12.04(b)(ii), any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written
consent (such consent not to be unreasonably withheld) of: 
  

	 	(A)	the Borrower, provided that no consent of the Borrower shall be required if such assignment is to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event
of Default has occurred and is continuing, is to any other assignee; and 

  

	 	(B)	the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment to an assignee that is a Lender immediately prior to
giving effect to such assignment, 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 or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or
Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less
than $5,000,000 and the amount of the Commitment of Loans of the assigning Lender after such assignment shall not be less than $5,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of
the Borrower shall be required if an Event of Default has occurred and is continuing; 

  
 92 

	 	(B)	each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement;

  

	 	(C)	the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of
$3,500; 

  

	 	(D)	the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire; and 

 

	 	(E)	The Assignee must not be a Defaulting Lender or an Affiliate of the Borrower. 

(iii) Subject to Section 12.04(b)(iv) and the acceptance and recording thereof, 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 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 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 and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Bank
and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for
inspection by the Borrower, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice. In connection with any changes to the Register, if necessary, the Administrative Agent will reflect the revisions
on Annex I and forward a copy of such revised Annex I to the Borrower, the Issuing Bank and each Lender. 

  
 93 

 (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
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, the Administrative Agent or the Issuing Bank, sell participations to one or more banks or other entities (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, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such
Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any
amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver
described in the first proviso to Section 12.02(b) that affects such Participant. In addition such agreement must provide that the Participant be bound by the provisions of Section 12.03. Subject to Section 12.04(c)(ii), 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(a). 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 agrees to be subject to Section 4.01(c) as though it were a Lender. 

(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. A Participant that
would be a Foreign Lender if it were a 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) as though it were a Lender. 
 (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, without limitation, any pledge or assignment to secure obligations to a Federal Reserve Bank or a central bank, and this
Section 12.04(d) 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. 

  
 94 

 (e) Notwithstanding any other provisions of this Section 12.04, no transfer or
assignment of the interests or obligations of any Lender or any grant of participations therein shall be permitted if such transfer, assignment or grant would require the Borrower and the Guarantors to file a registration statement with the SEC or
to qualify the Loans under the “Blue Sky” laws of any state. 
 Section 12.05. Survival; Revival;
Reinstatement. 
 (a) All covenants, agreements, representations and warranties made by the Borrower herein and in the
certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this
Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, any other Agent, the Issuing Bank 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 or any Letter of Credit is outstanding 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
Letters of Credit and the Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof. 
 (b) To the extent that any payments on the Secured Obligations or proceeds of any collateral are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Secured Obligations so satisfied shall be revived and continue as if such payment or proceeds had not been
received and the Administrative Agent’s and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each Loan Document shall continue in full force and effect. In such event, each Loan Document shall be
automatically reinstated and the Borrower shall take such action as may be reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement. 
 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 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. 

  
 95 

 (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 telecopy, facsimile or other similar electronic means 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 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 limitation 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 Subsidiary against any of and all the obligations of the
Borrower or any 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. 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. 

Section 12.09. GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS. 

(a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS EXCEPT TO THE
EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CONTRACT FOR, CHARGE, RECEIVE, RESERVE OR TAKE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED. CHAPTER 346 OF THE TEXAS FINANCE CODE (WHICH REGULATES
CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT OR THE NOTES. 
 (b)
ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS, 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

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 ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (iii) CERTIFIES THAT NO PARTY HERETO NOR
ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (iv) ACKNOWLEDGES THAT IT HAS BEEN
INDUCED TO ENTER INTO THIS AGREEMENT, THE LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 12.09. 

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, the Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that
Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such Information and required to keep such Information confidential), (b) to the extent requested by 

  
 97 

 
any regulatory authority having authority over the Administrative Agent or any Lender, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal
process, (d) to any other party to this Agreement or any other Loan Document, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or
any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section 12.11, to (i) any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations under this Agreement (provided that such Person agrees to be bound by the provisions of this Section 12.11) or (ii) any actual or prospective counterparty (or its
advisors) to any Swap Agreement relating to the Borrower and its obligations (provided that such Person agrees to be bound by the provisions of this Section 12.11), (g) with the consent of the Borrower or (h) to the extent such
Information (i) becomes publicly available other than as a result of a breach of this Section 12.11 or (ii) becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other
than the Borrower. For the purposes of this Section 12.11, “Information” means all information received from the Borrower or any Subsidiary relating to the Borrower or any Subsidiary and their businesses, other than any such
information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Borrower or a Subsidiary or otherwise identified by the Borrower as being nonconfidential. Any Person
required to maintain the confidentiality of Information as provided in this Section 12.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of
such Information as such Person would accord to its own confidential information. 
 Section 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. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it
(including the laws of the United States of America and the State of Texas or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event,
notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into in connection with or as security for the Notes, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest
under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under any of the Loan Documents or agreements or otherwise in connection with the Notes shall under no circumstances exceed the maximum
amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Secured Obligations (or, to the extent that the principal amount of the
Secured Obligations shall have been or would thereby be paid in full, refunded by such Lender to the Borrower); and (ii) in the event that the maturity of the Notes is accelerated by reason of an election of the holder thereof resulting from
any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount
allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by
such Lender on the principal amount of the Secured Obligations (or, to the extent that the principal amount of the Secured Obligations shall have been or would thereby be paid in full, refunded by

  
 98 

 
such Lender to the Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such
Lender, be amortized, prorated, allocated and spread throughout the stated term of the Loans evidenced by the Notes until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount
allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.12 and
(ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such
Lender, then the amount of interest payable to such Lender in respect of such subsequent interest computation period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to
such Lender shall equal the total amount of interest which would have been payable to such Lender if the total amount of interest had been computed without giving effect to this Section 12.12. To the extent that Chapter 303 of the Texas Finance
Code is relevant for the purpose of determining the Highest Lawful Rate applicable to a Lender, such Lender elects to determine the applicable rate ceiling under such Chapter by the weekly ceiling from time to time in effect. Chapter 346 of the
Texas Finance Code does not apply to the Borrower’s obligations hereunder. 
 Section 12.13. EXCULPATION
PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE
NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL
NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.”

 Section 12.14. Collateral Matters; Swap Agreements. The benefit of the Security Instruments and of the provisions
of this Agreement relating to any collateral securing the Secured Obligations shall also extend to and be available to any Lender or any Affiliate of a Lender that is counterparty to any Swap Agreement with the Borrower or any of its Subsidiaries
(including any Swap Agreement between such Persons in existence prior to the date hereof) on a pro rata basis in respect of any obligations of the Borrower or any of its Subsidiaries which arise

  
 99 

 
under any such Swap Agreement. If any Lender or any Affiliate of a Lender ceases to be a Lender under this Agreement, then the benefit of the Security Instruments and such provisions will
continue to apply to the Swap Agreements to which such Lender or its Affiliate is a party at the time that Lender ceases to be a Lender, but will not apply to any Swap Agreements entered into by that Lender or any of its Affiliates after that date.
No Lender or any Affiliate of a Lender shall have any voting rights under any Loan Document as a result of the existence of obligations owed to it under any such Swap Agreements. 

Section 12.15. No Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to
make Loans and the Issuing Bank to issue, amend, renew or extend Letters of Credit hereunder are solely for the benefit of the Borrower, and no other Person (including, without limitation, any Subsidiary of the Borrower, any obligor, contractor,
subcontractor, supplier or materialsman) shall have any rights, claims, remedies or privileges hereunder or under any other Loan Document against the Administrative Agent, any other Agent, the Issuing Bank or any Lender for any reason whatsoever.
There are no third party beneficiaries. 
 Section 12.16. Flood Insurance. Notwithstanding any provision in this
Agreement, any Mortgage or other Loan Document to the contrary, in no event is any Building (as defined in the applicable Flood Insurance Regulation) or Manufactured (Mobile) Home (as defined in the applicable Flood Insurance Regulation) included in
the definition of “Mortgaged Property” and no Building or Manufactured (Mobile) Home is hereby encumbered by any Security Instrument or other Loan Document. As used herein, “Flood Insurance Regulations” shall mean (i) the
National Flood Insurance Act of 1968 as now or hereafter in effect or any successor statute thereto, (ii) the Flood Disaster Protection Act of 1973 as now or hereafter in effect or any successor statute thereto, (iii) the National Flood
Insurance Reform Act of 1994 (amending 42 USC 4001, et. seq.), as the same may be amended or recodified from time to time, and (iv) the Flood Insurance Reform Act of 2004 and any regulations promulgated thereunder. 

Section 12.17. 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.
