Ladies and Gentlemen:

Concho Resources Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representative (the “Representative”), $850,000,000 aggregate principal amount of its 5.5% Senior Notes due 2023 (the “Securities”). The Securities will be issued pursuant to an Indenture dated as of September 18, 2009 (the “Base Indenture”), as amended and supplemented by the Seventh Supplemental Indenture (herein so called) dated as of August 17, 2012 (the Base Indenture, as so amended and supplemented, being called the “Indenture”) among the Company, the guarantors listed in Schedule 2 hereto (the “Guarantors”) and Wells Fargo Bank, National Association, as trustee (the “Trustee”), and will be guaranteed on an unsecured senior basis by each of the Guarantors (the “Guarantees”).

The Company previously issued $700,000,000 aggregate principal amount of its 5.5% Senior Notes due 2023 (the “Existing Securities”) under the Indenture. The Securities constitute an issuance of “Additional Notes” under the Indenture. The Securities will be treated as a single series with the Existing Securities and will have the same terms and conditions as the Existing Securities except as otherwise described in the Time of Sale Information (as defined below).

Each of the Company and the Guarantors hereby confirms its agreement with the several Underwriters concerning the purchase and sale of the Securities, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a

registration statement on Form S-3 (File No. 333-184037), including a prospectus, relating to the Securities. Such registration statement, including any post-effective amendments thereto and the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means the prospectus dated September 21, 2012 included in such registration statement that omits Rule 430 Information and the preliminary prospectus supplement (the “Preliminary Prospectus Supplement”) filed with the Commission pursuant to Rule 424(b) under the Securities Act on May 20, 2013, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities. Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be and any reference to “amend,” “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the time when sales of the Securities were first made (the “Time of Sale”), the Company had prepared the following information (collectively, the “Time of Sale Information”): the Preliminary Prospectus and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex B hereto.

2. Purchase of the Securities by the Underwriters. (a) The Company agrees to issue and sell the Securities to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 hereto at a price equal to 102.25% of the principal amount thereof plus accrued interest, if any, from April 1, 2013 to the Closing Date (as defined below). Tudor, Pickering, Holt & Co. Securities, Inc., acting as a “qualified independent underwriter” within the meaning of Rule 5121 of the Financial Industry Regulatory Authority, Inc. (“FINRA”) has participated in the preparation of the Preliminary Prospectus Supplement and has exercised the usual standards of due diligence with respect thereto. The Company will not be obligated to deliver any of the Securities except upon payment for all the Securities to be purchased as provided herein.

(b) The Company understands that the Underwriters intend to make a public offering of the Securities as soon after the effectiveness of this Agreement as in the judgment of the Representative is advisable, and initially to offer the Securities on the terms set forth in the Prospectus. The Company acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter.

The Global Note will be made available for inspection by the Representative not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date.

(e) The Company and the Guarantors acknowledge and agree that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company and the Guarantors with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company, the Guarantors or any other person.

The Company and the Guarantors shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company or the Guarantors with respect thereto. Any review by the Underwriters of the Company, the Guarantors, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company or the Guarantors.

(f) Ongoing Compliance. If during the Prospectus Delivery Period (i) any event shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Prospectus to comply with law, the Company will promptly notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representative may designate, such amendments or supplements to the Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law.

During the period from the date hereof through and including the date that is 45 days after the date hereof, the Company will not, without the prior written consent of the Representative, offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by the Company and having a tenor of more than one year.

(j) Use of Proceeds. The Company will apply the net proceeds from the sale of the Securities as described in the Registration Statement, the Time of Sale Information and the Prospectus under the heading “Use of Proceeds.”

(k) No Stabilization. The Company will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities.

(a) It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus,” as defined in Rule 405 under the Securities Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company) other than (i) a free writing prospectus that, solely as a result of use by such underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433, (ii) any Issuer Free Writing Prospectus listed on Annex B or prepared pursuant to Section 3(c) or Section 4(c) above, or (iii) any free writing prospectus prepared by such Underwriter and approved by the Company in advance in writing (each such free writing prospectus referred to in clauses (i) or (iii), an “Underwriter Free Writing Prospectus”). Notwithstanding the foregoing, the Underwriters may use a term sheet substantially in the form of Annex C hereto without the consent of the Company.

The Company and each of the Guarantors jointly and severally agree to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required

to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

The Company and each of the Guarantors also jointly and severally agree to indemnify and hold harmless Tudor, Pickering, Holt & Co. Securities, Inc., its affiliates, directors and officers and each person, if any, who controls Tudor, Pickering, Holt & Co. Securities, Inc. within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities incurred as a result of Tudor, Pickering, Holt & Co. Securities, Inc.’s participation as a “qualified independent underwriter” within the meaning of FINRA Rule 5121 of FINRA in connection with the offering of the Securities.

(b) Indemnification of the Company and the Guarantors. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of the Guarantors, each of their respective directors, their respective officers who signed the Registration Statement and each person, if any, who controls the Company or any of the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed that the only such information consists of the following: the information contained in the fifth paragraph and the third and fourth sentences of the seventh paragraph under the caption “Underwriting.”

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such

proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred, provided, however that if indemnity may be sought pursuant to the second paragraph of Section 7(a) above in respect of such proceeding, then in addition to such separate firm of the Underwriters, their affiliates and such control persons of the Underwriters, the indemnifying party shall be liable for the fees and expenses of not more than one separate firm (in addition to any local counsel) for Tudor, Pickering, Holt & Co. Securities, Inc. in its capacity as a “qualified independent underwriter,” its affiliates, directors, officers and all persons, if any, who control Tudor, Pickering, Holt & Co. Securities, Inc. within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by Merrill Lynch, Pierce, Fenner & Smith Incorporated, any such separate firm for Tudor, Pickering, Holt & Co. Securities, Inc. in its capacity as a “qualified independent underwriter,” its affiliates, directors, officers and all persons, if any, who control Tudor, Pickering, Holt & Co. Securities, Inc. within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act shall be designated in writing by Tudor, Pickering, Holt & Co. Securities, Inc. and any such separate firm for the Company, the Guarantors, their respective directors, their respective officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person 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 Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (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 Underwriters or Tudor, Pickering, Holt & Co. Securities, Inc. in its capacity as a “qualified independent underwriter,” as the case may be, on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Guarantors on the one hand and the Underwriters or Tudor, Pickering, Holt & Co. Securities, Inc. in its capacity as a “qualified independent underwriter,” as the case may be, on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company and the Guarantors on the one hand and the Underwriters or Tudor, Pickering, Holt & Co. Securities, Inc. in its capacity as a “qualified independent underwriter,” as the case may be, on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or any Guarantor or by the Underwriters or Tudor, Pickering, Holt & Co. Securities, Inc. in its capacity as a “qualified independent underwriter,” as the case may be, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company, the Guarantors and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, 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 on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

10. Defaulting Underwriter. (a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to

purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

11. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company and each of the Guarantors jointly and severally agree to pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s and the Guarantors’ counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related reasonable fees and expenses of counsel for the Underwriters); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all application fees incurred in connection with any filing with, and clearance of the offering by, FINRA; and (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; provided that notwithstanding clause (ix) above, the Underwriters shall pay one-half of the lease expenses associated with any airplane which is used for the purposes of such “road show” presentations.

(b) If (i) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (ii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement (other than Section 9, but excluding any termination of this Agreement by the Representative pursuant to clause (ii) thereof), the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the reasonable fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

A-1-2

Such counsel shall also state that they have participated in conferences with representatives of the Company and with representatives of its independent accountants and counsel at which conferences the contents of the Registration Statement, the Time of Sale Information and the Prospectus and any amendment and supplement thereto and related matters were discussed and, although such counsel assume no responsibility for, or express any opinion regarding (other than as listed in opinions (7) and (10) above), the accuracy, completeness or fairness of the Registration Statement, the Time of Sale Information, the Prospectus and any amendment or supplement thereto (except as expressly provided above), based upon the participation described above (relying as to factual matters in respect to the determination by such counsel of materiality to the extent such counsel deems reasonable upon statements of fact made to such counsel by representatives of the Company) and subject to the next succeeding sentence, nothing has come to the attention of such counsel to cause such counsel to believe that the Registration Statement, at the time of its effective date (including the information, if any, deemed pursuant to Rule 430A, 430B or 430C to be part of the Registration Statement at the time of effectiveness), contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, that the Time of Sale Information, at the Time of Sale (which such counsel may assume to be the date of the Underwriting Agreement) contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or that the Prospectus or any amendment or supplement thereto as of its date and the Closing Date contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary to

A-1-3

make the statements therein, in the light of the circumstances under which they were made, not misleading. In making the foregoing statement, such counsel will not express any comment or belief with respect to the Form T-1 and the financial statements and related schedules, including the notes and schedules thereto and the auditor’s report thereon, and any other financial, accounting and oil and gas reserve and related net revenue or discounted cash flow information, included in or omitted from the Registration Statement, the Time of Sale Information or the Prospectus.

In rendering such opinion, such counsel may rely as to matters of fact on certificates of responsible officers of the Company, the Guarantors and public officials that are furnished to the Underwriters.

The opinion of Vinson & Elkins L.L.P. described above shall be rendered to the Underwriters at the request of the Company and shall so state therein.

Additional Information

Offering Size

The Company has increased the offering of the notes from $500 million aggregate principal amount to $850 million aggregate principal amount. Corresponding changes will be made wherever applicable to the preliminary prospectus supplement, including as discussed below.

Use of Proceeds

The following disclosure under “Use of Proceeds” on page S-21 and each other location where it appears in the preliminary prospectus supplement is amended to read as follows:

We expect the net proceeds from this offering to be approximately $868.1 million, after deducting estimated fees and expenses (including underwriting discounts and commissions) but disregarding accrued interest paid by buyers of the new notes.

We intend to use the net proceeds from this offering to fund our pending Tender Offer and Consent Solicitation obligations under the Tender Offer and Consent Solicitation for the 2017 Notes and to pay down borrowings outstanding under our credit facility, which had a balance of $467.4 million as of March 31, 2013. We will use the remaining net proceeds from this offering for general corporate purposes. There is no assurance that the Tender Offer will be subscribed for in any amount. In the event that all of the 2017 Notes are not acquired in the Tender Offer, we intend (but are not obligated) to redeem any 2017 Notes that remain outstanding, although the timing of any such redemption is within our discretion.

C-2

A repayment of a portion of the outstanding borrowings under our credit facility could result in at least 5% of the net proceeds of this offering being paid to certain affiliates of the underwriters who are lenders under our credit facility. Accordingly, this offering will be made in compliance with the requirements of Rule 5121 of the Financial Industry Regulatory Authority. In addition, certain of the underwriters or their affiliates are holders of our 2017 Notes and, accordingly, may receive a portion of the net proceeds of this offering in the Tender Offer. For more information, see “Conflicts of Interest.”

Conflicts of Interest

The following disclosure under “Summary—The Offering—Conflicts of interest” on page S-6 and each other location where it appears in the preliminary prospectus supplement is amended to read as follows:

We intend to use any remaining net proceeds following our repurchase of 2017 Notes in the Tender Offer to repay a portion of the outstanding borrowings under our credit facility, which could result in at least 5% of the net proceeds of this offering being paid to certain affiliates of the underwriters who are lenders under our credit facility. See “Use of Proceeds.” Accordingly, this offering is being made in compliance with the requirements of Rule 5121 of the Financial Industry Regulatory Authority. This rule provides that if at least 5% of the net proceeds from the sale of debt securities, not including underwriting compensation, are used to reduce or retire the balance of a loan or credit facility extended by the underwriters or their affiliates, a “qualified independent underwriter” meeting certain standards must participate in the preparation of this prospectus supplement and exercise the usual standards of due diligence with respect thereto. Tudor, Pickering, Holt & Co. Securities, Inc. is assuming the responsibilities of acting as the qualified independent underwriter in connection with this offering. For more information, see “Conflicts of Interest.” In addition, certain of the underwriters or their affiliates are holders of our 2017 Notes and, accordingly, may receive a portion of the net proceeds of this offering in the Tender Offer. For more information, see “Conflicts of Interest.”
