Ladies and Gentlemen:

Laredo Petroleum, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule 1 hereto (collectively, the “Underwriters”), for whom you are acting as representative (the “Representative”), an aggregate of 13,000,000 shares (the “Underwritten Shares”) of common stock, par value $0.01 per share, of the Company (the “Common Stock”). The Company also proposes to sell to the Underwriters, at the option of the Underwriters, up to an additional 1,950,000 shares of Common Stock (the “Option Shares”), if and to the extent the Underwriters have determined to exercise the right to purchase such Option Shares granted to the Underwriters in Section 2(a) hereof. The Underwritten Shares and the Option Shares are herein referred to as the “Shares.” The shares of Common Stock to be outstanding after giving effect to the sale of the Shares are referred to herein as the “Stock.”

The Company hereby confirms its agreement with the several Underwriters concerning the purchase and sale of the Shares, as follows:

1. Registration Statement. The Company has prepared and filed with the U.S. 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”) on Form S-3, an “automatic shelf registration statement” (as defined in Rule 405 under the Securities Act) (File No. 333-209887), including a base prospectus (the “Base Prospectus”), relating to certain securities, including the Shares, and such registration statement became effective upon filing in accordance with Rule 462(e) under the Securities Act. Such registration statement, as amended by any post-effective amendments thereto as of the date of this Agreement, including the information, if any, deemed pursuant to Rule 430B 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 Base Prospectus, as supplemented by any prospectus supplement relating to the Shares filed with the Commission pursuant to Rule 424(b) under the Securities Act that omits Rule 430 Information, and the term “Prospectus” means the Base

Prospectus, as supplemented by the prospectus supplement relating to the Shares 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 Shares. 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 and Exchange Act of 1934, as amended (“Exchange Act”), and the rules and regulations of the Commission thereunder 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 Pricing Disclosure Package (as defined below).

At or prior to the Applicable Time (as defined below), the Company had prepared the following information (collectively, with the pricing information set forth on Annex B, the “Pricing Disclosure Package”): a Preliminary Prospectus, dated July 14, 2016, filed with the Commission pursuant to Rule 424(b) under the Securities Act and each “free writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex B hereto, if any.

2. Purchase of the Shares by the Underwriters.

In addition, the Company agrees to sell the Option Shares to the several Underwriters, and the Underwriters, on the basis of the representations and warranties and agreements herein contained and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, from the Company up to 1,950,000 Option Shares at the Purchase Price; provided, however, that the amount paid by the Underwriters for any such Option Shares shall be reduced by an amount per share equal to any dividends declared by the Company and payable on the Underwritten Shares but not payable on such Option Shares. If any Option Shares are to be purchased, then the number of Option Shares to be purchased by each Underwriter shall be a number of Option Shares which bears the same ratio to the aggregate number of Option Shares being purchased as the number of Underwritten Shares set forth opposite the name of such Underwriter in Schedule 1 hereto (or such number increased as set forth in Section 10 hereof) bears to the aggregate number of Underwritten Shares being purchased by the several Underwriters, subject, however, to such adjustments to eliminate any fractional Shares as the Representative in its sole discretion may make. The Underwriters may

exercise the option to purchase Option Shares at any time in whole, or from time to time in part, on or before the thirtieth day following the date of this Agreement, by written notice from the Representative to the Company. Such notice shall set forth the aggregate number of Option Shares as to which the option is being exercised and the date and time when such Option Shares are to be delivered and paid for, which may be the same date and time as the Closing Date (as hereinafter defined) but shall not be earlier than the Closing Date or later than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 10 hereof). Any such notice shall be given at least two business days prior to the date and time of delivery specified therein.

(b) The Company understands that the Underwriters intend to make a public offering of the Shares as soon after the effectiveness of this Agreement as in the judgment of the Representative is advisable, and initially to offer the Shares on the terms set forth in the Prospectus. The Company acknowledges and agrees that the Underwriters may offer and sell Shares to or through any of their respective affiliates.

(c) Payment for the Underwritten Shares shall be made by wire transfer in immediately available funds to the account(s) specified by the Company (or its representatives) to the Representative, at the offices of Akin Gump ▇▇▇▇▇▇▇ ▇▇▇▇▇ & ▇▇▇▇ LLP, ▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇ at 10:00 A.M., New York City time, on July 19, 2016, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representative and the Company may agree upon in writing. Payment for any Option Shares shall be made by wire transfer in immediately available funds to the account(s) specified by the Company to the Representative, on the date and at the time and place specified by the Representative in the written notice of the Underwriters’ election to purchase such Option Shares.

(d) The Company acknowledges and agrees that each of the Underwriters is acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Shares 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 or any other person. Additionally, neither the Representative nor any other Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for

making its own independent investigation and appraisal of the transactions contemplated hereby, and neither the Representative nor any other Underwriter shall have any responsibility or liability to the Company with respect thereto. Any review by the Representative (whether acting on behalf of the Underwriters or itself) or any other Underwriter of the Company, and the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Representative or such Underwriter, as the case may be, and shall not be on behalf of the Company.

7. Indemnification and Contribution.

(a) Indemnification of the Underwriters by the Company. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) such Underwriter, and the successors and assigns of all the foregoing persons, 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 included or incorporated by reference 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, (ii) or any untrue statement or alleged untrue statement of a material fact included or incorporated by reference in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), 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 the Underwriters consists of the information described as such in subsection (b) below.

(b) Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company 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 Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), it being understood and agreed upon that the only such information furnished by the Underwriters consists of the following information furnished on behalf of each Underwriter and set forth under the caption “Underwriting” in the Prospectus: (i) the names of the Underwriters in the table set forth in the first paragraph, and (ii) the statements set forth in the fourth, ninth, thirteenth, fourteenth and fifteenth paragraphs.

(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 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 reasonable 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 proceedings in the same jurisdiction, be liable for the reasonable 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 paid or reimbursed as they are incurred. 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 the Representative; any such separate firm for the Company, its directors, its 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. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. 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) or (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, on the one hand, and the Underwriters on the other, from the offering of the Shares 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, on the one hand, and the Underwriters 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, 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 Shares 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 Shares. The relative fault of the Company, on the one hand, and the Underwriters 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 by the Underwriters 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 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 Shares 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 Underwriters, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option Shares, prior to any Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the Exchange, the Nasdaq Stock Market, the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities or a material disruption in securities settlement or clearance services in the United States shall have occurred 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 Underwriters, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date or any Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus.

10. Defaulting Underwriter.

(a) If, on the Closing Date or any Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, then the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares 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 Shares, 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 Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, then either the non-defaulting Underwriters or the Company may postpone the Closing Date or any Additional Closing Date, as the case may be, for up to five (5) 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, the Pricing Disclosure Package, the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement, the Pricing Disclosure Package 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 Shares that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters or the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or any Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares 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 Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters or the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or any Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Shares to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Shares on any Additional Closing Date 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 will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the sale, preparation and delivery of the Shares 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 Pricing Disclosure Package and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the fees and expenses of the Company’s counsel and independent accountants; (iv) the fees and expenses incurred in connection with the registration or qualification of the Shares under the state or foreign securities or Blue Sky laws of such jurisdictions as the Representative may reasonably designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related reasonable fees and expenses of counsel for the Underwriters); (v) the cost of preparing stock certificates; (vi) the costs and charges of any transfer agent and any registrar; (vii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, FINRA, including reasonable fees and expenses of Underwriters’ counsel in an amount not to exceed $15,000; and (viii) all costs and expenses of the Company’s officers and employees and any other expenses of the Company relating to any investor or “road show” presentations in connection with the offering and sale of the Shares, including, without limitation, any travel expenses of the Company’s officers and employees and any other expenses of the Company.

(b) If (i) this Agreement is terminated pursuant to Section 9, (ii) the Company for any reason fails to tender the Shares for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Shares for any reason permitted under this Agreement, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of Underwriters’ counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

12. Persons Entitled to Benefit of Agreement.

This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the affiliates, officers and directors and any controlling persons referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Shares from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

13. Survival.

The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Shares and shall

remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Underwriters.

14. Certain Defined Terms.

For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act.

15. Miscellaneous.

The statements in the Pricing Disclosure Package and the Final Prospectus under the caption “Certain U.S. Federal Income Tax Considerations For Non-U.S. Holders of Shares of Our Common Stock,” insofar as such statements constitute a summary of the United States Federal tax laws referred to therein, as of the date of the Pricing Disclosure Package and the Final Prospectus, in all material respects, are accurate and fairly summarize the United States federal tax laws referred to therein, subject to the qualifications and assumptions stated therein.

13. The Company is not and, after giving effect to the Offering and sale of the [Firm] Shares contemplated by the Underwriting Agreement and the application of the net proceeds from the sale of the [Firm] Shares as described in the Preliminary Prospectus and the Final Prospectus, will not be, required to register as an “investment company,” as such term is defined under the Investment Company Act of 1940, as amended.

Annex A-1 to Underwriting Agreement

14. The Registration Statement was automatically effective under the Securities Act on March 2, 2016. To our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission. The filing of the Final Prospectus pursuant to Rule 424 under the Securities Act was made in the manner and within the time period required by such rule.

For purposes of this letter, we have assumed the information in the Final Prospectus Supplement of the type referred to in Rule 430B(f)(1) of the General Rules and Regulations under the Securities Act was deemed to be a part of and included in the Registration Statement pursuant to such Rule 430B(f)(1) as of the date of the Underwriting Agreement. Our identification of documents and other information described on Annex A hereto as part of the Pricing Disclosure Package has been at your request and with your approval. Such identification is for the limited purpose of making the statements set forth in this letter (including, without limitation, the views expressed in subparagraph (c) of the last paragraph of this letter as to material misstatements or omissions) and is not the expression of a view by us as to whether any such documents and information has been or should have been conveyed to investors generally or to any particular investors at any particular time or in any particular manner.

Because the primary purpose of our professional engagement was not to establish or confirm factual matters, financial or accounting information or reserve or production information included in the Registration Statement, the Pricing Disclosure Package and the Final Prospectus, and because many determinations involved in the preparation of the Registration Statement, the Pricing Disclosure Package and the Final Prospectus are of a wholly or partially non-legal character, except as expressly set forth in paragraphs 3(b), 11 and 12 herein, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the Final Prospectus or the Pricing Disclosure Package (the “Disclosure Documents”) and we make no representation that we have independently verified the accuracy, completeness or fairness of such statements.

However, in the course of our acting as special counsel to the Company in connection with the preparation of the Registration Statement, the Pricing Disclosure Package and the Final Prospectus, we have reviewed each Disclosure Document and have participated in conferences and telephone conversations with representatives of the Company, representatives of the independent public accountants for the Company, representatives of the independent reserve engineers of the Company, representatives of the Underwriters and representatives of the Underwriters’ counsel, during which conferences and conversations the contents of such Disclosure Documents and related matters were discussed.

Based on our participation in such conferences and conversations, our review of the documents described above, our understanding of the United States Federal securities Laws and the experience we have gained in our practice thereunder, we advise you that:

(a) Each of the Registration Statement, as of the date of the Final Prospectus, the Preliminary Prospectus, as of its date, and the Final Prospectus, as of its date, appeared on its face to be appropriately responsive in all material respects to the requirements of the Securities

Annex A-1 to Underwriting Agreement

Act, except that we express no view as to the financial statements, financial schedules and other financial and accounting data and reserve and production information contained or incorporated by reference therein or omitted therefrom;

(b) There are no documents known to us that are required to be filed under the Securities Act as exhibits to the Registration Statement that are not so filed as required in all material respects, nor are there any documents known to us that are required under the Securities Act to be summarized in the Final Prospectus in the manner specified in the Securities Act that are not so summarized as required in all material respects, except that we express no view as to the financial statements, financial schedules and other financial and accounting data and reserve and production information so required to be filed or summarized; and

(c) No information has come to our attention that causes us to believe that (i) the Registration Statement, as of the date of the Final Prospectus, contained an 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; (ii) the Pricing Disclosure Package, as of 8:29 a.m. (central time) on July 14, 2016 (which you have informed us is a time prior to the time of the first sale of the [Firm] Shares by the Underwriters), contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading or (iii) the Final Prospectus, as of the date of the Final Prospectus Supplement and as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that in the case of each of clauses (i)-(iii) above, we do not express any view as to the financial statements, financial schedules and other financial and accounting data and reserve and production information contained or incorporated by reference therein or omitted therefrom.
