MERRILL LYNCH, PIERCE, FENNER & SMITH

INCORPORATED
As Representative of the Initial Purchasers

One Bryant Park
New York, New York 10036

Ladies and Gentlemen:

Introductory. Laredo Petroleum, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several Initial Purchasers named in Schedule A (the “Initial Purchasers”), acting severally and not jointly, the respective amounts set forth in such Schedule A of a $450,000,000 aggregate principal amount of the Company’s 5.625% Senior Notes due 2022 (the “Notes”). Merrill Lynch, Pierce, Fenner & Smith Incorporated has agreed to act as the representative of the several Initial Purchasers (the “Representative”) in connection with the offering and sale of the Notes.

Prior to the date hereof, the Company completed an internal corporate reorganization, pursuant to which the following transactions, which are collectively referred to herein as the “Reorganization,” occurred:

A. Laredo Petroleum Texas, LLC and Laredo Petroleum—Dallas, Inc., two former subsidiaries of Laredo Petroleum, Inc., merged with and into Laredo Petroleum, Inc., with Laredo Petroleum, Inc. surviving the merger;

B. Laredo Gas Services, LLC, the sole remaining wholly owned subsidiary of Laredo Petroleum, Inc., changed its name to Laredo Midstream Services, LLC;

C. Laredo Petroleum, Inc., a wholly owned subsidiary of Laredo Petroleum Holdings, Inc., a Delaware corporation (“Holdings”), merged with and into Holdings, with Holdings surviving the merger; and

D. Holdings changed its name to Laredo Petroleum, Inc.

The effective time of the Reorganization (other than the transaction described under clause B. above) was 9:00 a.m., on December 31, 2013 (the “Reorganization Effective Time”). As used herein, the “Company” shall mean Holdings prior to the Reorganization Effective Time and Laredo Petroleum, Inc. at and after the Reorganization Effective Time. Prior to the Reorganization Effective Time, the Company had four wholly owned subsidiaries: Laredo Petroleum, Inc., Laredo Petroleum Texas, LLC, Laredo Gas Services, LLC, and Laredo Petroleum—Dallas, Inc. At and after the Reorganization Effective Time and as of the date hereof, the Company’s only wholly owned subsidiary is Laredo Midstream Services, LLC (the “Initial Guarantor”).

The Securities (as defined below) will be issued pursuant to an indenture, to be dated as of January 23, 2014 (the “Indenture”), among the Company, the Initial Guarantor and Wells Fargo Bank, National Association, 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”), pursuant to a letter of representations (the “DTC Agreement”) to be dated on or before the Closing Date (as defined in Section 2 hereof), from the Company to the Depositary.

The holders of the Notes will be entitled to the benefits of a registration rights agreement, to be dated as of January 23, 2014 (the “Registration Rights Agreement”), among the Company, the Initial Guarantor and the Initial Purchasers, pursuant to which the Company and the Initial Guarantor may be required to file with the Commission (as defined below), under the circumstances set forth therein, (i) a registration statement under the Securities Act (as defined below) relating to another series of debt securities of the Company with terms substantially identical to the Notes (the “Exchange Notes”) to be offered in exchange for the Notes (the “Exchange Offer”) and (ii) to the extent required by the Registration Rights Agreement, a shelf registration statement pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Notes, and in each case, to use its commercially reasonable efforts to cause such registration statements to be declared effective. All references herein to the Exchange Notes and the Exchange Offer are only applicable if the Company and the Initial Guarantor are in fact required to consummate the Exchange Offer pursuant to the terms of the Registration Rights Agreement.

The payment of principal of and 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 Initial Guarantor and (ii) any subsidiary of the Company formed or acquired after the Closing Date that executes a supplemental indenture 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 related thereto are herein collectively referred to as the “Securities;” and the Exchange Notes and the Guarantees related thereto are herein collectively referred to as the “Exchange Securities.”

This Purchase Agreement (this “Agreement”), the Registration Rights Agreement, the DTC Agreement, the Securities, the Exchange Securities and the Indenture are collectively 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 the Securities shall be deemed to have agreed that the 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 January 13, 2014 (the “Preliminary Offering Memorandum”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement, dated January 13, 2014 (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 “Preliminary Offering Memorandum,” “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.

Neither the Company nor the Initial Guarantor has received any notice of infringement or conflict with asserted intellectual property rights of others, which infringement or conflict, if the subject of an unfavorable decision, would reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change.

(w) Rights-of-Way. The Company and the Initial Guarantor have such consents, easements, rights-of-way or licenses from any person (“rights-of-way”) as are necessary to enable the Company and the Initial Guarantor to conduct their respective businesses in the manner described in the Offering Memorandum, except for such rights-of-way the failure of which to obtain would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change. The rights-of-way owned by the Company and the Initial Guarantor are subject only to such qualifications, reservations and encumbrances as may be set forth in the Offering Memorandum or as would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change.

Except as otherwise disclosed in the Offering Memorandum, there is no material tax deficiency that has been, or could reasonably be expected to be, asserted against the Company or the Initial Guarantor or any of their respective properties or assets. The Company has made adequate charges, accruals and reserves in accordance with GAAP in the applicable financial statements referred to in Section 1(n) hereof in respect of all federal, state and foreign income and franchise taxes for all periods as to which the tax liability of the Company or the Initial Guarantor has not been finally determined.

(z) Insurance. The Company and the Initial Guarantor are insured with policies in such amounts and with such deductibles and covering such losses and risks as are reasonably adequate and customary to protect them and their businesses, taken as a whole, in a manner consistent with other businesses similarly situated. The Company has no reason to believe that it or the Initial Guarantor will not be able to (i) renew its existing insurance coverage as and when such policies expire or (ii) 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 reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change.

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 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 to perform any agreement herein or to comply with any provision hereof, the Company agrees 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 the Initial Guarantor, on the other hand, hereby agree to observe the following procedures in connection with the offer and sale of the Securities:

(a) Offers and sales of the Securities will be made only by the Initial Purchasers or Affiliates thereof qualified to do so in the jurisdictions in which such offers or sales are made. 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 Securities (and all securities issued in exchange therefor or in substitution thereof, other than the Exchange Securities) 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 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 (i) (a) TO A PERSON WHO IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (b) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT, (c) OUTSIDE THE UNITED STATES TO A NON-U.S. PERSON IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 904 UNDER THE SECURITIES ACT, OR (d) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF

COUNSEL IF THE COMPANY SO REQUESTS), (ii) TO THE COMPANY, OR (iii) 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 FROM IT 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.

SECTION 8. Indemnification.

(a) Indemnification of the Initial Purchasers. Each of the Company and the Initial Guarantor, 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 or is otherwise permitted by Section 8(d)), 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 reasonable fees and disbursements of counsel chosen by the Representative) 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 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). The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company or the Initial Guarantor may otherwise have.

(b) Indemnification of the Company and the Initial Guarantor. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, the Initial Guarantor, each of their respective directors, officers, employees and each person, if any, who controls the Company or the Initial 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, the Initial Guarantor or any such 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 such Initial Purchaser or is otherwise permitted by Section 8(d)), 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 with written information furnished to the Company by such Initial Purchaser through the Representative expressly for use therein; and to reimburse the Company, the Initial Guarantor and each such director, officer, employee or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by the Company, the Initial Guarantor or such director 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 Initial Guarantor hereby acknowledges that the only information that the Initial Purchasers through the Representative have furnished to the Company 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 the seventh full paragraph of page (ii) of, and the information set forth in the table in the first paragraph, the first sentence of the fifth paragraph, the third sentence of the seventh paragraph, and the first and second sentences of the tenth paragraph 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 that 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 that 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 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 more than one separate counsel (together with local counsel (in each jurisdiction)), approved by the indemnifying party (Merrill Lynch, Pierce, Fenner & Smith Incorporated in the case of Sections 8(b) and 9 hereof), 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, which will not be unreasonably withheld, 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. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 8, the indemnifying party agrees that it 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 such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the

date of such settlement. 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 Initial Guarantor, 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 Initial Guarantor, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions that 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 Initial Guarantor, 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 Initial Guarantor, 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 relates to information supplied by the Company and the Initial Guarantor, 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.

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 Initial Guarantor 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 that 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, officer or employee of the Company or the Initial Guarantor, and each person, if any, who controls the Company or the Initial Guarantor within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company and the Initial Guarantor, as applicable.

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 materially limited by the Commission, or trading in securities generally on either the Nasdaq Stock Market or the NYSE, shall have been suspended or materially 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 Delaware 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 in United States’ or international political, financial or economic conditions, in each such case, 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; or (iv) in the judgment of the Representative there shall have occurred any Material Adverse Change. Any termination pursuant to this Section 10 shall be without liability on the part of (i) the Company or the Initial Guarantor to any Initial Purchaser, except that the Company and the Initial Guarantor 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 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 Initial Guarantor, 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, the Initial 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.

9 hereof, and in each case their respective successors, and no other person will have any right or obligation hereunder. The term “successors” shall not include any Subsequent Purchaser or other purchaser of the Securities as such from any of the Initial Purchasers merely by reason of such purchase.

SECTION 14. Authority of the Representative. Any action by the Initial Purchasers hereunder may be taken by the Representative on behalf of the Initial Purchasers, and any such action taken by the Representative shall be binding upon the Initial Purchasers.

SECTION 15. Partial Unenforceability.

THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED 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.

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 9hereof 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 a defaulting Initial Purchaser of any liability it may have to the Company, the Initial Guarantor or any non-defaulting Initial Purchaser for damages by its default.

SECTION 18. No Advisory or Fiduciary Responsibility. Each of the Company and the Initial Guarantor 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 Initial Guarantor, on the one hand, and the several Initial Purchasers, on the other hand, and the Company and the Initial Guarantor 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 Initial Guarantor or their respective Affiliates, equityholders, creditors or employees or any other party; (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Company and the Initial Guarantor 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 Initial Guarantor on other matters) or any other obligation to the Company and the Initial Guarantor 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 Initial Guarantor, 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 Initial Guarantor 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 Initial Guarantor and the several Initial Purchasers, or any of them, with respect to the subject matter hereof. The Company and the Initial Guarantor hereby waive and release, to the fullest extent permitted by law, any claims that the Company and the Initial Guarantor may have against the several Initial Purchasers with respect to any breach or alleged breach of fiduciary duty.

SECTION 19. 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)), the Initial Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Company, 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 (e.g., a “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart thereof. 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.

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to the Company the enclosed copies hereof, whereupon this instrument, along with all counterparts hereof, shall become a binding agreement in accordance with its terms.

EXHIBIT A-1

FORM OF OPINION OF COUNSEL TO THE COMPANY

We have acted as special counsel to Laredo Petroleum, Inc., a Delaware corporation (the “Issuer”), in connection with the offering and sale (the “Offering”) of $450,000,000 aggregate principal amount of the Issuer’s 5.625% Senior Notes due 2022 (the “Securities”) pursuant to the Purchase Agreement, dated January 13, 2014 (the “Purchase Agreement”), among the Issuer, Laredo Midstream Services, LLC, a Delaware limited liability company (the “Guarantor”), and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representative (the “Representative”) of the several initial purchasers (the “Initial Purchasers”) named in Schedule A to the Purchase Agreement. This opinion is rendered at the request of the Issuer pursuant to Section 5(c) of the Purchase Agreement. All capitalized terms used in this letter without definition have the meanings assigned to them in the Purchase Agreement.

In connection with this letter, we have examined executed originals or copies of executed originals of each of the following documents, each of which is dated as of the date hereof unless otherwise noted (collectively, the “Examined Documents”):

the Purchase Agreement;

the Preliminary Offering Memorandum, dated January 13, 2014 (together with the documents incorporated therein by reference, the “Preliminary Offering Memorandum”);

the Pricing Supplement, dated January 13, 2014 (the “Pricing Supplement”), relating to the Securities specified on Annex A (together with the Preliminary Offering Memorandum, the “Pricing Disclosure Package”);

the Final Offering Memorandum, dated January 13, 2014 (together with the documents incorporated therein by reference, the “Final Offering Memorandum”);

the Indenture, dated as of January 23, 2014 (including the provisions of the Trust Indenture Act (the “TIA”) that are deemed pursuant to Section 318(c) thereof to be a part of and govern such indenture, the “Indenture”), among the Issuer, the Guarantor and Wells Fargo Bank, National Association, as trustee (the “Trustee”);

the Registration Rights Agreement, dated as of January 23, 2014 (the “Registration Rights Agreement” and, together with the Indenture, the Purchase Agreement, the Securities and the Exchange Securities, the “Transaction Documents”), among the Issuer, the Guarantor and the Initial Purchasers; and

the global certificates evidencing the Securities.

In addition, we have examined the following documents (collectively, the “Due Diligence Documents”):

Exhibit A-1-1

(a)                                 officers’ and secretaries’ certificates executed by officers and secretaries of the Issuer and the Guarantor;

(b)                                 the other certificates and other closing documents delivered by the Issuer and the Guarantor in connection with the Purchase Agreement;

(c)                                  the written authentication order of the Issuer authorizing the issuance of the Securities pursuant to Section [2.02] of the Indenture;

(d)                                 the orders, writs, judgments or decrees listed on Exhibit A attached hereto;

(e)                                  copies of the governing documents of the Issuer and the Guarantor listed on Exhibit B attached hereto (the “Governing Documents”);

(f)                                   the good standing certificates of the Issuer and the Guarantor listed on Exhibit C attached hereto (the “Good Standing Certificates”); and

(g)                                  resolutions of each of the board of directors or the managers, as applicable, of the Issuer and the Guarantor authorizing the Issuer and the Guarantor to execute and deliver the Transaction Documents.

We have examined originals or certified copies of such corporate or other entity records of the Issuer and the Guarantor and other certificates and documents of officials of the Issuer, the Guarantor, public officials and others as we have deemed appropriate for purposes of this letter. As to various questions of fact relevant to this letter, we have relied, without independent investigation, upon the Due Diligence Documents, certificates of public officials, certificates of officers of the Issuer and the Guarantor and the representations and warranties of the Issuer, the Guarantor and the Initial Purchasers in the Purchase Agreement, all of which we assume to be true, correct and complete. We have made no investigation or review of any matters related to the Issuer, the Guarantor or any other person or entity, including governmental authorities (“Person”), other than as expressly listed herein. In addition, we have made no inquiry of the Issuer, the Guarantor or any other Person regarding, and no review of, any judgments, orders, decrees, franchises, licenses, certificates, permits or other public records or agreements to which the Issuer or the Guarantor are a party other than the Examined Documents and the Due Diligence Documents.

The Issuer or the Guarantor may use or have used other law firms to represent the Issuer or Guarantor in connection with other matters, including, without limitation, regulatory matters and matters other than such matters in connection with the Examined Documents. The scope of the matters addressed in this letter is necessarily limited due to the limited scope of our representation.

We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to authentic original documents of all copies submitted to us as conformed, certified or reproduced copies, that the certificates for the Securities and the Exchange Securities conform to the specimens thereof we have reviewed and

Exhibit A-1-2

that the Securities and the Exchange Securities will be duly authenticated in accordance with the terms of the Indenture. In our examination of documents, we have also assumed the legal capacity of natural persons, the corporate or other entity power and due authorization of each Person not a natural person (other than, solely with respect to the Transaction Documents, the Issuer and the Guarantor) to execute and deliver such documents and to consummate the transactions contemplated thereby, the due execution and delivery of each such document by all parties thereto (other than, solely with respect to the Transaction Documents, the Issuer and the Guarantor) and that each such document constitutes the legal, valid and binding obligation of each party thereto (other than, solely with respect to the Transaction Documents, the Issuer and the Guarantor), enforceable against such party in accordance with its terms.

Based upon the foregoing and subject to the assumptions, exceptions, qualifications and limitations set forth herein, we are of the opinion that:

1.                                      The Issuer is validly existing as a corporation and in good standing under the laws of the State of Delaware, the jurisdiction of its organization. The Guarantor is validly existing as a limited liability company and in good standing under the laws of the State of Delaware, the jurisdiction of its organization.

2.                                      Each of the Issuer and the Guarantor has all requisite corporate or limited liability company, as applicable, power and authority to execute and deliver, and incur and perform its respective obligations under, the Transaction Documents.

3.                                      The execution and delivery by each of the Issuer and the Guarantor of the Transaction Documents to which it is a party and the performance by each of the Issuer and the Guarantor of its respective obligations thereunder have been duly authorized by all necessary corporate or limited liability company, as applicable, action by the Issuer and the Guarantor. Each of the Purchase Agreement, the Indenture and the Registration Rights Agreement has been duly and validly authorized, executed and delivered by each of the Issuer and the Guarantor.

4.                                      The Securities have been duly and validly authorized and executed by the Issuer and, when authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of the Purchase Agreement, will be valid and legally binding obligations of the Issuer, entitled to the benefits of the Indenture and enforceable against the Issuer in accordance with their terms. The Exchange Securities have been duly and validly authorized by the Issuer and, when duly executed, authenticated, issued and delivered as provided in the Indenture and the Registration Rights Agreement, will constitute valid and legally binding obligations of the Issuer, enforceable against the Issuer in accordance with their terms.

5.                                      The Indenture (including, with respect to the Guarantor, (i) when the Securities have been duly and validly authenticated in accordance with the terms of the Indenture and duly and validly paid for by and delivered to the Initial Purchasers in accordance with the terms of the Purchase Agreement, the guarantee of the

Exhibit A-1-3

Guarantor in respect of the Securities provided for in Article [Ten] of the Indenture and (ii) when the Exchange Securities have been duly executed, authenticated, issued and delivered as provided in the Indenture and the Registration Rights Agreement, the guarantee of the Guarantor in respect of the Exchange Securities provided for in Article [Ten] of the Indenture) constitutes the valid and legally binding obligation of each of the Issuer and the Guarantor, enforceable against each of the Issuer and the Guarantor in accordance with its terms.

6.                                      The Registration Rights Agreement is a valid and legally binding obligation of each of the Issuer and the Guarantor, enforceable against the Issuer and the Guarantor in accordance with its terms.

7.                                      The execution and delivery of the Transaction Documents by each of the Issuer and the Guarantor party thereto does not, and the performance by the Issuer and the Guarantor of its respective obligations under the Transaction Documents to which it is a party will not, (a) result in any violation of any law, statute, rule or regulation of or under any Included Law (as defined below) (including Regulations T, U and X of the Board of Governors of the Federal Reserve System), (b) result in any violation of the Governing Documents of the Issuer or the Guarantor, or (c) result in any violation of any order, writ, judgment or decree under any Included Law of any New York or Federal governmental authority or regulatory body applicable to the Issuer or the Guarantor or their assets or properties listed on Exhibit A attached hereto.

8.                                      No authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body (each, a “Filing”) is required under any of the Included Laws for the due execution and delivery of the Transaction Documents by the Issuer and the Guarantor party thereto and the performance by the Issuer and the Guarantor of its respective obligations under the Transaction Documents to which it is a party, subject to the assumptions set forth in paragraph 12 and except for (i) routine Filings necessary in connection with the conduct of the business of the Issuer and the Guarantor, (ii) such other Filings as have been obtained or made, and (iii) Filings under Federal and state securities Laws as required by the Registration Rights Agreement.

9.                                      The statements in the Preliminary Offering Memorandum(1) and the Final Offering Memorandum under the caption “Description of the Notes” and “Description of

(1)         Qualification in opinion letter will state that any reference to “Preliminary Offering Memorandum” in opinion paragraphs 9, 10 and 11 shall mean the Preliminary Offering Memorandum as supplemented by the information contained in the Pricing Supplement.

Exhibit A-1-4

Other Indebtedness,” insofar as such statements purport to summarize certain provisions of documents referred to therein and reviewed by us as described above, fairly summarize such provisions in all material respects, subject to the qualifications and assumptions stated therein. The statements in the Preliminary Offering Memorandum and the Final Offering Memorandum under the caption “Description of the Notes” and “Description of Other Indebtedness,” insofar as such statements purport to summarize provisions of any law, statute, rule or regulation of or under any Included Law referred to therein, fairly summarize such laws, statutes, rules and regulations in all material respects, subject to the qualifications and assumptions stated therein. The Indenture and the Securities conform, and the Exchange Securities, when duly executed, authenticated, issued and delivered as provided in the Indenture and the Registration Rights Agreement, will conform, in all material respects as to legal matters to the descriptions thereof under the heading “Description of the Notes” in the Preliminary Offering Memorandum and the Final Offering Memorandum (in the case of the Preliminary Offering Memorandum, when considered together with the Pricing Supplement).

10.                               The statements in the Preliminary Offering Memorandum and the Final Offering Memorandum under the caption “Certain Material United States Federal Income Tax Considerations,” insofar as such statements constitute a summary of the United States Federal tax laws referred to therein, as of the date of the Preliminary Offering Memorandum and the Final Offering Memorandum, 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.

11.                               The Issuer and the Guarantor are not, and after giving effect to the offering and sale of the Securities contemplated by the Purchase Agreement and the application of the net proceeds from such sale as described in the Preliminary Offering Memorandum and the Final Offering Memorandum, the Issuer and the Guarantor will not be, required to register as an “investment company,” as such term is defined under the Investment Company Act of 1940, as amended.

12.                               Assuming without independent investigation, (a) that the Securities are sold to the Initial Purchasers, and initially resold by the Initial Purchasers, in accordance with the terms of and in the manner contemplated by, the Purchase Agreement and the Final Offering Memorandum; (b) the accuracy of the representations and warranties of the Issuer and the Guarantor set forth in the Purchase Agreement and the matters certified in those certain certificates delivered on the date hereof; (c) the accuracy of the representations and warranties of the Initial Purchasers set forth in the Purchase Agreement; (d) the due performance and compliance by the Issuer, the Guarantor and the Initial Purchasers of their respective covenants and agreements set forth in the Purchase Agreement; and (e) the Initial Purchasers’ compliance with the transfer procedures and restrictions described in the Final Offering Memorandum, it is not necessary to register the Securities under the Securities Act or to qualify an indenture in respect thereof under the TIA in

Exhibit A-1-5

connection with the issuance and sale of the Securities by the Issuer to the Initial Purchasers or in connection with the offer, resale and delivery of the Securities by the Initial Purchasers in the manner contemplated by the Purchase Agreement and the Final Offering Memorandum, it being expressly understood that we express no opinion in this paragraph 12 or paragraph 8 as to any subsequent offer or resale of any of the Securities.

13.                               The Indenture conforms in all material respects to the requirements of the TIA and the rules and regulations of the Commission applicable to an indenture which is qualified thereunder.

Our identification of documents and information 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 and is not the expression of a view by us as to whether any such 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 data and information or information pertaining to natural resource reserves and production, and our participation in the preparation of the documents incorporated by reference in the Pricing Disclosure Package and the Final Offering Memorandum has been limited, and because many determinations involved in the preparation of the Pricing Disclosure Package and the Final Offering Memorandum are of a wholly or partially non-legal character, except as expressly set forth in paragraphs 9 and 10 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 Final Offering Memorandum 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 Issuer in connection with the preparation of the Final Offering Memorandum and the Pricing Disclosure Package, we have reviewed each Disclosure Document and have participated in conferences and telephone conversations with representatives of the Issuer, representatives of the independent public accountants for the Issuer, representatives of the independent reserve engineers of the Issuer, representatives of the Initial Purchasers and representatives of the Initial Purchasers’ 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 periodic and current reports filed by the Issuer under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), to the extent incorporated by reference in the Preliminary Offering Memorandum and the Final Offering Memorandum (except the financial statements, financial schedules or other financial or accounting data and

Exhibit A-1-6

information or information pertaining to natural resource reserves and production contained in, or omitted from, such reports, as to which we express no view) (the “Incorporated Documents”), at the time it was filed with the Securities and Exchange Commission (the “Commission”), appeared on its face to comply as to form in all material respects to the requirements of the particular form under the Exchange Act and the applicable rules and regulations promulgated by the Commission thereunder, except that we express no view as to the antifraud provisions of the Federal securities Laws and the rules and regulations promulgated under such provisions; and

(b) we have no reason to believe that (i) the Final Offering Memorandum, as of its date or as of the Closing Date, 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 or (ii) the Pricing Disclosure Package, as of the Time of Sale (which you have informed us is a time after the Pricing Supplement specified on Annex A was made available to investors), 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 were made, not misleading; it being understood that we express no opinion as to the financial statements, financial schedules or other financial or accounting data and information or information pertaining to natural resource reserves and production contained in, or omitted from, the Pricing Disclosure Package or the Final Offering Memorandum.

FORM OF OPINION OF GENERAL COUNSEL

I am Senior Vice President and General Counsel to (a) Laredo Petroleum, Inc., a Delaware corporation (the “Issuer”), and (b) Laredo Midstream Services, LLC, a Delaware limited liability company (the “Guarantor”). This opinion letter is furnished to you in connection with the offering and sale (the “Offering”) of $450,000,000 aggregate principal amount of the Issuer’s 5.625% Senior Notes due 2022 (the “Securities”) pursuant to the Purchase Agreement, dated January 13, 2014 (the “Purchase Agreement”), among the Issuer, the Guarantor and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representative (the “Representative”) of the several initial purchasers (the “Initial Purchasers”) named in Schedule A to the Purchase Agreement. This opinion is rendered at the request of the Issuer pursuant to Section 5(c) of the Purchase Agreement. All capitalized terms used in this letter without definition have the meanings assigned to them in the Purchase Agreement.

In connection with this letter, I have examined executed originals or copies of executed originals of each of the following documents:

(i)                                     the Purchase Agreement;

(ii)                                  the Preliminary Offering Memorandum, dated January 13, 2014 (together with the documents incorporated therein by reference, the “Preliminary Offering Memorandum”);

(iii)                               the Pricing Supplement, dated January 13, 2014 (the “Pricing Supplement”), relating to the Securities specified on Annex A (together with the Preliminary Offering Memorandum, the “Pricing Disclosure Package”);

(iv)                              the Final Offering Memorandum, dated January 13, 2014 (together with the documents incorporated therein by reference, the “Final Offering Memorandum”);

(v)                                 the Indenture, dated as of January 23, 2014 (including the provisions of the Trust Indenture Act (the “TIA”) that are deemed pursuant to Section 318(c) thereof to be a part of and govern such indenture, the “Indenture”), among the Issuer, the Guarantor and Wells Fargo Bank, National Association, as trustee (the “Trustee”); and

(vii)                           the Registration Rights Agreement, dated as of January 23, 2014 (the “Registration Rights Agreement” and, together with the Indenture, the Purchase Agreement, the Securities and the Exchange Securities, the “Transaction Documents”), among the Issuer, the Guarantor and the Initial Purchasers.

Additionally, I have examined the following documents (collectively, the “Due Diligence Documents”): (a) copies of the documents described in Exhibit A attached

Exhibit A-2-1

hereto (the “Governing Documents”); (b) the documents described in Exhibit B attached hereto (the “Good Standing Documents”); and (c) the documents described in Exhibit C attached hereto (the “Material Agreements”).

In rendering the opinions expressed below, I have also examined originals or copies of all certificates of public officials and such other documents and records as I deem appropriate as a basis for the opinions hereinafter expressed. As to various questions of fact relevant to this opinion letter, I have made such inquiry of the Issuer and the Guarantor and their files and records as I have deemed appropriate and I have relied, without independent investigation, upon the Due Diligence Documents, certificates of public officials, certificates of officers of the Issuer and the Guarantor and the representations and warranties of the Issuer, the Guarantor and the Initial Purchasers in the Purchase Agreement, all of which I assume to be true, correct and complete. I wish to inform you that my knowledge is necessarily limited due to the limited scope of my review.

I have assumed the genuineness of all signatures, the authenticity of all documents submitted to me as originals, the conformity to authentic original documents of all copies submitted to me as conformed, certified or reproduced copies. I have also assumed the legal capacity of natural persons, the corporate or other entity power and due authorization of each Person not a natural person other than the Issuer and the Guarantor to execute and deliver the Transaction Documents and to consummate the transactions contemplated by the Transaction Documents, the due execution and delivery of the Transaction Documents by all parties thereto other than the Issuer and the Guarantor, and that each Transaction Document constitutes the legal, valid and binding obligation of each party thereto other than the Issuer and the Guarantor, enforceable against such party in accordance with its terms.

Based upon the foregoing and subject to the assumptions, exceptions, qualifications and limitations set forth hereinafter, I am of the opinion that:

1.                                      The Issuer has been duly incorporated as a corporation, and is validly existing and in good standing under the laws of the State of Delaware, the jurisdiction of its organization. The Guarantor has been duly formed as a limited liability company, and is validly existing and in good standing under the laws of the State of Delaware, the jurisdiction of its organization.

3.                                      The Guarantor is duly qualified and is in good standing as a foreign corporation in the State of Oklahoma. The Guarantor is duly qualified and has the right to transact business as a foreign corporation in the State of Texas.
