Ladies and Gentlemen:

Introductory. Matador Resources Company, a Texas corporation (the “Company”), proposes to issue and sell to BofA Securities, Inc. (“BofA Securities”) and the other several Initial Purchasers named in Schedule A hereto (the “Initial Purchasers”), acting severally and not jointly, the respective amounts set forth in such Schedule A of $500,000,000 aggregate principal amount of the Company’s 6.875% Senior Notes due 2028 (the “Notes”). BofA Securities has agreed to act as the representative of the several Initial Purchasers (the “Representative”) in connection with the offering and sale of the Notes.

The Notes will be issued pursuant to an indenture, to be dated as of April 11, 2023 (the “Indenture”), among the Company, the Guarantors (as defined below) and Computershare Trust Company, N.A., as trustee (the “Trustee”). The Notes will be issued only in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”).

The payment of principal of, premium, if any, and interest on the Notes will be fully and unconditionally guaranteed on a senior unsecured basis, jointly and severally by (i) the entities listed on the signature pages hereof as “Guarantors” and (ii) any subsidiary of the Company formed or acquired after the Closing Date that executes an additional guarantee in accordance with the terms of the Indenture, and their respective successors and assigns (collectively, the “Guarantors”), pursuant to their guarantees (the “Guarantees”). The Notes and the Guarantees attached thereto are herein collectively referred to as the “Securities”.

This Agreement, the Securities and the Indenture are referred to herein as the “Transaction Documents.”

The Company understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and in the Pricing Disclosure Package (as defined below) and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (the “Subsequent Purchasers”) on the terms set forth in the Pricing Disclosure Package (the first time when sales of the Securities are made is referred to as the “Time of Sale”). The Securities are to be offered and sold to or through the Initial Purchasers without being registered with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933 (as amended, the “Securities Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder), in reliance upon exemptions therefrom. Pursuant to the terms of the Securities and the Indenture, investors who acquire Securities shall be deemed to have agreed that Securities may only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemptions afforded by Rule 144A under the Securities Act (“Rule 144A”) or Regulation S under the Securities Act (“Regulation S”)).

The Company has prepared and delivered to each Initial Purchaser copies of a Preliminary Offering Memorandum, dated April 3, 2023 (the “Preliminary Offering Memorandum”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement, dated April 3, 2023 (the “Pricing Supplement”), describing the terms of the Securities, each for use by such Initial Purchaser in connection with its solicitation of offers to purchase the Securities. The Preliminary Offering Memorandum and the Pricing Supplement are herein referred to as the “Pricing Disclosure Package.” Promptly after this Agreement is executed and delivered, the Company will prepare and deliver to each Initial Purchaser a final offering memorandum dated the date hereof (the “Final Offering Memorandum”).

All references herein to the terms “Pricing Disclosure Package” and “Final Offering Memorandum” shall be deemed to mean and include all information filed under the Securities Exchange Act of 1934 (as amended, the “Exchange Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder) prior to the Time of Sale and incorporated by reference in the Pricing Disclosure Package (including the Preliminary Offering Memorandum) or the Final Offering Memorandum, as the case may be, and all references herein to the terms “amend,” “amendment” or “supplement” with respect to the Final Offering Memorandum shall be deemed to mean and include all information filed under the Exchange Act after the Time of Sale and incorporated by reference in the Final Offering Memorandum.

The Company hereby confirms its agreement with the Initial Purchasers as follows:

None of the Company, its Affiliates, or any person acting on its or any of their behalf (other than the Initial Purchasers, as to whom the Company makes no representation or warranty) has engaged or will engage, in connection with the offering of the Securities, in any form of general solicitation or general advertising within the meaning of Rule 502 under the Securities Act or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act.

The Company and each of the Subsidiaries are duly qualified to transact business and are in good standing in all jurisdictions in which the conduct of their business requires such qualification; except where the failure to be so qualified or to be in good standing would

5

not reasonably be expected, individually or in the aggregate, (i) to have a material adverse effect on the condition (financial or otherwise), properties, assets, operations, earnings, business or prospects of the Company and its Subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business or (ii) to materially impair the consummation of the transactions contemplated hereby (clauses (i) and (ii) are referred to hereinafter as a “Material Adverse Effect”).

(l) Capitalization. The information set forth under the caption “Capitalization” in the Offering Memorandum is true and correct (other than for subsequent issuances of capital stock, if any, pursuant to employee benefit plans described in the Offering Memorandum or upon exercise of outstanding options or warrants described in the Pricing Disclosure Package and the Offering Memorandum, as the case may be). The outstanding shares of common stock of the Company (the “Common Stock”) have been duly authorized and validly issued and are fully paid and non-assessable.

Such financial statements and related schedules have been prepared in accordance with U.S. generally accepted principles of accounting, consistently applied throughout the periods involved (“GAAP”), except as disclosed therein, and all adjustments necessary for a fair presentation of results for such periods have been made. The summary financial and statistical data included or incorporated by reference in the Offering Memorandum presents fairly in all material respects the information shown therein and such data has been compiled on a basis consistent with the financial statements presented therein and the books and records of the Company.

Since the date of the most recent balance sheet of the Company and its consolidated Subsidiaries reviewed or audited by KPMG LLP, and reviewed by the Audit Committee of the Board of Directors of the Company, (i) the Company has not been advised of (A) any significant deficiencies in the design or operation of Internal Controls that could adversely affect the ability of the Company and each of its Subsidiaries to record, process, summarize and report financial data, or any material weaknesses in Internal Controls and (B) any fraud, whether or not material, that involves management or other employees who have a significant role in the Internal Controls of the Company and each of its Subsidiaries, and (ii) since that date, there have been no significant changes in Internal Controls or in other factors that could significantly affect Internal Controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

(q) Disclosure Controls and Procedures. The Company has established and maintains “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act); the Company’s “disclosure controls and procedures” are reasonably designed to ensure that all information (both financial and non-financial) required to be disclosed by the Company in the reports that it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and regulations of the Commission, and that all such information is accumulated and communicated to the Company’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the Chief Executive Officer and Chief Financial Officer of the Company required under the Exchange Act with respect to such reports.

(s) No Material Actions or Proceedings. Except as set forth in the Offering Memorandum, there is no action, suit, claim or proceeding pending or, to the knowledge of the Company or the Guarantors, threatened against or affecting the Company or any of the Subsidiaries, before any court or administrative agency or which has as the subject thereof any property owned or leased by the Company or any of the Subsidiaries (i) that are required by the Securities Act to be disclosed on a registration statement on Form S-3 and which is not so disclosed in the Offering Memorandum or (ii) which, if determined adversely to the Company or any of its Subsidiaries, would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(t) Title to Properties. Each of the Company and its Subsidiaries has (i) good and defensible title to all of the oil and gas properties (including oil and gas wells, producing leasehold interests and appurtenant personal property) owned by the Company and its Subsidiaries, title investigations having been carried out by the Company or its Subsidiaries consistent with the reasonable practice in the oil and gas industry in the areas in which the Company and its Subsidiaries operate and (ii) good title to all other real and personal property owned by the Company and its Subsidiaries, including but not limited to such other real and personal property reflected in the financial statements of the Company and its Subsidiaries included and incorporated by reference in the Offering Memorandum, in each case free and clear of all restrictions, mortgages, pledges, security interests, claims, liens, encumbrances, charges and defects except such as (x) are described in the Offering Memorandum, (y) liens and encumbrances under operating agreements, unitization and pooling agreements, production sales contracts, farm-out agreements and other oil and gas exploration participation and production agreements, in each case that secure payment of amounts not yet due and payable for the performance of other unmatured obligations and are of a scope and nature customary in the oil and gas industry or arise in connection with drilling and production operations or (z) such as do not affect the value of the properties of the Company and its Subsidiaries, considered as one enterprise, and do not interfere in any respect with the use made and proposed to be made of such properties by the Company and its Subsidiaries, considered as one enterprise, with such exceptions as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. All of the leases and subleases under which the Company or any of its Subsidiaries holds or uses properties described in the Offering Memorandum are in full force and effect, with such exceptions as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, and neither the Company nor any of its Subsidiaries has any notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company or its Subsidiaries under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Company or any Subsidiary thereof to the continued possession or use of the leased or subleased premises, in each case, with such exceptions as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. The

8

working interests in oil, gas and mineral leases or mineral interests which constitute a portion of the real property held by the Company reflect in all material respects the right of the Company to explore, develop or receive production from such real property, and the care taken by the Company and its Subsidiaries with respect to acquiring or otherwise procuring such leases or mineral interests was generally consistent with standard industry practices in the areas in which the Company and its Subsidiaries operate for acquiring or procuring leases and interests therein to explore, develop or produce for hydrocarbons.

(u) Rights-of-Way. The Company and its Subsidiaries have such consents, easements, rights-of-way or licenses from any person (“rights-of-way”) as are necessary to enable the Company and its Subsidiaries to conduct its business in the manner described in the Offering Memorandum, subject to such qualifications as may be set forth in the Offering Memorandum, and except for such rights-of-way the lack of which would not have, individually or in the aggregate, a Material Adverse Effect.

(v) Tax Law Compliance. The Company and the Subsidiaries have filed all federal, state, local and foreign tax returns which have been required to be filed and have paid all taxes indicated by said returns and all assessments received by them or any of them to the extent that such taxes have become due and payable by them, except (in any case) (i) for such taxes and assessments that are being contested in good faith and for which an adequate reserve for accrual has been established in accordance with GAAP, (ii) for any such taxes or assessments that are currently payable without penalty or interest, (iii) where a failure to do so would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or (iv) to the extent described in the Offering Memorandum. Neither the Company nor any of the Guarantors has knowledge of any actual or proposed additional material tax assessments. There are no transfer taxes or other similar fees or charges under U.S. federal law or the laws of any U.S. state, or any political subdivision thereof, required to be paid in connection with the execution and delivery of this Agreement or the issuance or sale by the Company of the Notes.

The Company and the Subsidiaries have no material liabilities or obligations, or indirect or direct contingent obligations, that are not disclosed in the Company’s financial statements that are incorporated by reference in the Offering Memorandum.

The execution and delivery of the Transaction Documents and the consummation of the transactions herein contemplated and the fulfillment of the terms hereof will not conflict with or result in a breach of any of the terms or provisions of, or constitute a default under (1) the Charter or Bylaws of the Company, (2) any contract, indenture, mortgage, deed of trust or other agreement or instrument to which the Company or any of the Subsidiaries is a party, or (3) any order, rule or regulation applicable to the Company or any of the Subsidiaries of any court or of any regulatory body or administrative agency or other governmental body having jurisdiction over the Company or any of the Subsidiaries or any of their respective properties, except, with respect to clauses (2) and (3), where such conflicts, breaches or defaults would not, individually or in the aggregate, result in a Material Adverse Effect.

10

(z) All Necessary Permits, etc. The Company and each of the Subsidiaries has all licenses, certifications, permits, franchises, approvals, clearances and other regulatory authorizations (“Permits”) from governmental authorities as are necessary to conduct its businesses as currently conducted and to own, lease and operate its properties in the manner described in the Offering Memorandum except as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. There is no claim, proceeding or controversy, pending or, to the knowledge of the Company or any of the Subsidiaries, threatened, involving the status of or sanctions under any of the Permits and no event has occurred that might allow for the revocation, termination, modification or other impairment of the rights of the Company or any of the Subsidiaries under such Permit, except, for such claims, proceedings, controversies or events as would not, individually or in the aggregate, have a Material Adverse Effect.

(aa) No Price Stabilization or Manipulation. Neither the Company nor any of the Guarantors has taken, directly or indirectly, any action designed to cause or result in, or which has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(bb) Company and Guarantors Not an “Investment Company”. Neither the Company nor any of the Guarantors is, and after giving effect to the offering and the sale of the Securities and the application of the proceeds thereof as described in the Offering Memorandum will be, an “investment company” within the meaning of such term under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Investment Company Act”).

(cc) Insurance. The Company and each of the Guarantors and the Company’s significant subsidiaries (within the meaning of Regulation S-X under the Exchange Act) (the “Significant Subsidiaries”) carry, or are covered by, insurance in such amounts and covering such risks as is commercially reasonable for the conduct of their respective businesses and the value of their respective properties and as is customary for companies engaged in similar industries. All policies of insurance insuring the Company or any Guarantor or the Significant Subsidiaries or any of their respective businesses, assets, employees, officers and directors are in full force and effect, and the Company and the Guarantors and the Significant Subsidiaries are in compliance with the terms of such policies in all material respects. There are no claims by the Company or any Guarantor or the Significant Subsidiaries under any such policy or instrument as to which an insurance company is denying liability or defending under a reservation of rights clause. The Company has no reason to believe that it or any Guarantor or the Significant Subsidiaries will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not have, individually or in the aggregate, a Material Adverse Effect.

(dd) ERISA Compliance. The Company is in compliance in all material respects with all presently applicable provisions of the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder (“ERISA”); no “reportable event” (as defined in ERISA) has occurred with respect to any “pension plan” (as defined in ERISA) for which the Company would have any liability; the Company has not incurred and does not expect to incur liability under

11

(i) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (ii) Section 412 or 4971 of the Internal Revenue Code of 1986, as amended, including the regulations and published interpretations thereunder (the “Code”); and each “pension plan” for which the Company would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification.

(ee) Solvency. Each of the Company and the Guarantors is, and immediately after the Closing Date will be, Solvent.

23

If any condition specified in this Section 5 is not satisfied when and as required to be satisfied, this Agreement may be terminated by the Representative by notice to the Company at any time on or prior to the Closing Date, which termination shall be without liability on the part of any party to any other party, except that Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination.

SECTION 6. Reimbursement of Initial Purchasers’ Expenses. If this Agreement is terminated by the Representative pursuant to Section 5 or clauses (i), (iv) or (v) of Section 10 hereof, including if the sale to the Initial Purchasers of the Securities on the Closing Date is not consummated because of any refusal, inability or failure on the part of the Company or any Guarantor to perform any agreement herein or to comply with any provision hereof, the Company and the Guarantors jointly and severally agree to reimburse the Initial Purchasers, severally, upon demand for all out-of-pocket expenses that shall have been reasonably incurred by the Initial Purchasers in connection with the proposed purchase and the offering and sale of the Securities, including, without limitation, fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges.

SECTION 7. Offer, Sale and Resale Procedures. Each of the Initial Purchasers, on the one hand, and the Company and each of the Guarantors, on the other hand, hereby agree to observe the following procedures in connection with the offer and sale of the Securities:

(a) Each such offer or sale shall only be made to persons whom the offeror or seller reasonably believes to be Qualified Institutional Buyers or non-U.S. persons outside the United States to whom the offeror or seller reasonably believes offers and sales of the Securities may be made in reliance upon Regulation S upon the terms and conditions set forth in Annex I hereto, which Annex I is hereby expressly made a part hereof.

(b) No general solicitation or general advertising (within the meaning of Rule 502 under the Securities Act) will be used in the United States in connection with the offering of the Securities.

(c) Upon original issuance by the Company, and until such time as the same is no longer required under the applicable requirements of the Securities Act, the Notes (and all securities issued in exchange therefor or in substitution thereof) shall bear the following legend:

“THE SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THE SECURITY EVIDENCED HEREBY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE

24

EXEMPTION THEREFROM. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THE SECURITY EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) SUCH SECURITY MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1)(a) INSIDE THE UNITED STATES TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A UNDER THE SECURITIES ACT, (b) OUTSIDE THE UNITED STATES TO A FOREIGN PERSON IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 903 OR RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (c) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF APPLICABLE) OR (d) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY IF THE COMPANY SO REQUESTS), (2) TO THE COMPANY OR (3) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN EACH CASE, IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THE SECURITY EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN CLAUSE (A) ABOVE. NO REPRESENTATION CAN BE MADE AS TO THE AVAILABILITY OF THE EXEMPTION PROVIDED BY RULE 144 FOR RESALE OF THE SECURITY EVIDENCED HEREBY.”

Following the sale of the Securities by the Initial Purchasers to Subsequent Purchasers pursuant to the terms hereof, the Initial Purchasers shall not be liable or responsible to the Company or any of the Guarantors for any losses, damages or liabilities suffered or incurred by the Company or any of the Guarantors, including any losses, damages or liabilities under the Securities Act, arising from or relating to any resale or transfer of any Security.

25

SECTION 8. Indemnification.

(a) Indemnification of the Initial Purchasers. Each of the Company and the Guarantors, jointly and severally, agrees to indemnify and hold harmless each Initial Purchaser, its affiliates, directors, officers and employees, and each person, if any, who controls any Initial Purchaser within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Initial Purchaser, affiliate, director, officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and to reimburse each Initial Purchaser and each such affiliate, director, officer, employee or controlling person for any and all expenses (including the fees and disbursements of counsel chosen by BofA Securities) as such expenses are reasonably incurred by such Initial Purchaser or such affiliate, director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply, with respect to an Initial Purchaser, to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), it being acknowledged and agreed that any such written information is as set forth in Section 8(b) hereto. The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have.

(b) Indemnification of the Company and the Guarantors. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each Guarantor, each of their respective directors, officers and each person, if any, who controls the Company or any Guarantor within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, any Guarantor or any such director, officer or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Initial Purchaser), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), in reliance upon and in conformity

26

with written information furnished to the Company by or on behalf of such Initial Purchaser through the Representative expressly for use therein; and to reimburse the Company, any Guarantor and each such director, officer or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by the Company, any Guarantor or such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. Each of the Company and the Guarantors hereby acknowledges that the only information that the Initial Purchasers through the Representative have furnished to the Company in writing expressly for use in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto) are the statements set forth in: (i) the paragraph under the subcaption “Commissions and Discounts”, (ii) the third and fourth sentences of the first paragraph under the subcaption “New Issue of Notes” and (iii) the three paragraphs under the subcaption “Short Positions”, in each case under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Final Offering Memorandum. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Initial Purchaser may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; provided that the failure to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 8 except to the extent that it has been materially prejudiced by such failure (through the forfeiture of substantive rights and defenses) and shall not relieve the indemnifying party from any liability that the indemnifying party may have to an indemnified party other than under this Section 8. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof (other than the reasonable costs of investigation) unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of

27

more than one separate counsel (together with local counsel (in each applicable jurisdiction)), which shall be selected by BofA Securities (in the case of counsel representing the Initial Purchasers or their related persons), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

SECTION 9. Contribution. If the indemnification provided for in Section 8 hereof is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total discount received by the Initial Purchasers bear to the aggregate initial offering price of the Securities. The relative fault of the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Company and the Guarantors, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or inaccuracy.

28

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8 hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8 hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8 hereof for purposes of indemnification.

The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9.

Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in excess of the discount received by such Initial Purchaser in connection with the Securities distributed by it. No person guilty of fraudulent misrepresentation (within the meaning of Section 11 of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each affiliate, director, officer and employee of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director of the Company or any Guarantor, and each person, if any, who controls the Company or any Guarantor with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company and the Guarantors.

SECTION 10. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representative by notice given to the Company if at any time: (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by the New York Stock Exchange (the “NYSE”), or trading in securities generally on either the Nasdaq Stock Market or the NYSE shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such quotation system or stock exchange by the Commission or FINRA; (ii) a general banking moratorium shall have been declared by any of federal, New York or Texas authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representative is material and adverse and makes it impracticable or inadvisable to proceed with the offering sale or delivery of the Securities in the manner and on the terms described in the Pricing Disclosure Package or to enforce contracts for the sale of securities; (iv) in the judgment

29

of the Representative there shall have occurred any Material Adverse Effect; or (v) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representative may interfere materially with the conduct of the business and operations of the Company regardless of whether or not such loss shall have been insured. Any termination pursuant to this Section 10 shall be without liability on the part of (i) the Company or any Guarantor to any Initial Purchaser, except that the Company and the Guarantors shall be obligated to reimburse the expenses of the Initial Purchasers pursuant to Sections 4 and 6 hereof, (ii) any Initial Purchaser to the Company, or (iii) any party hereto to any other party except that the provisions of Sections 8 and 9 hereof shall at all times be effective and shall survive such termination.

SECTION 11. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Guarantors, their respective officers and the several Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser, the Company, any Guarantor or any of their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

SECTION 16. Governing Law Provisions. THIS AGREEMENT AND ANY CLAIM, CONTROVERSY, OR DISPUTE ARISING UNDER OR RELATING TO THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF.

(a) Consent to Jurisdiction. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for suits, actions, or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related Proceeding.

(b) Waiver of Jury Trial. Each of the parties hereto hereby waives any right to trial by jury in any suit or proceeding arising out of or relating to this Agreement

SECTION 17. Default of One or More of the Several Initial Purchasers. If any one or more of the several Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportions that the number of Securities set forth opposite their respective names on Schedule A bears to the aggregate number of Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing Date. If any one or more of the Initial Purchasers shall fail or refuse to purchase Securities and the aggregate number of Securities with respect to which such default occurs exceeds 10% of the aggregate number of Securities to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Company for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination. In any such case either the Initial Purchasers or the Company shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Final Offering Memorandum or any other documents or arrangements may be effected.

As used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 17. Any action taken under this Section 17 shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

SECTION 18. No Advisory or Fiduciary Responsibility. Each of the Company and the Guarantors acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Guarantors, on the one hand, and the several Initial Purchasers, on the other hand, and the Company and the Guarantors are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Initial Purchaser is and has been acting solely as a principal and is not the agent or fiduciary of the Company and the Guarantors or their respective affiliates, stockholders, creditors or employees or any other party; (iii) no Initial Purchaser has assumed or

32

will assume an advisory or fiduciary responsibility in favor of the Company and the Guarantors with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Company and the Guarantors on other matters) or any other obligation to the Company and the Guarantors except the obligations expressly set forth in this Agreement; (iv) the several Initial Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the Guarantors, and the several Initial Purchasers have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship; and (v) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby, and the Company and the Guarantors have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Guarantors and the several Initial Purchasers, or any of them, with respect to the subject matter hereof. The Company and the Guarantors hereby waive and release, to the fullest extent permitted by law, any claims that the Company and the Guarantors may have against the several Initial Purchasers with respect to any breach or alleged breach of fiduciary duty.

SECTION 19. Compliance With USA PATRIOT Act. In accordance with the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001), as amended), the Initial Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Company and the Guarantors, which information may include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective clients.

SECTION 20. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile or other electronic transmission (i.e., a “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart thereof. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Agreement or any document to be signed in connection with this Agreement shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

(a) In the event that any Initial Purchaser that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Initial Purchaser of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Initial Purchaser that is a Covered Entity or a BHC Act Affiliate of such Initial Purchaser becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Initial Purchaser are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

(c) For purposes of this Section 19, a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k). “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.
