(b) Indemnification of the Company.Each Initial Purchaser will severally and not jointly indemnify and hold harmless each of the Company, the Guarantors, each of their respective directors, each of their respective officers and each person, if any, who controls the Company or such Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, an “Initial Purchaser Indemnified Party”), against any losses, claims, damages or liabilities to which such

Initial Purchaser Indemnified Party may become subject, under the Securities Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Preliminary Offering Circular, Time of Sale Information or the Final Offering Circular, in each case as amended or supplemented, or any Issuer Written Communicationor arise out of or are based upon the omission or the alleged omission 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 reliance upon and in conformity with written information furnished to the Company by such Initial Purchaser through the Representative specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Initial Purchaser Indemnified Party in connection with investigating, preparing or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Initial Purchaser Indemnified Party is a party thereto) whether threatened or commenced based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Initial Purchaser consists of the following information in the Preliminary Offering Circular and Final Offering Circular furnished on behalf of each Initial Purchaser: the information contained in the fourth sentence of the eleventh paragraph and the thirteenth paragraph under the caption “Plan of distribution” (the “Initial Purchasers Information”); provided, however, that the Initial Purchasers shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Company’s failure to perform its obligations under Section 4(f) of this Agreement as a result of a change in the Initial Purchasers Information, but only so long as the Initial Purchasers had timely provided to the Company written notice of the change so as to permit the Company to meet its obligations under Section 4(f).

(c) Actions against Parties; Notification.Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (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 party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigationunless (i) the indemnifying party and the indemnified party shall have mutually agreed to the contrary; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party 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 party; or (iv) the named parties

in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party 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 party shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any reasonably necessary local counsel) for all indemnified parties, and that all such reasonable fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Initial Purchaser, its officers, employees, agents, partners, members, directors and its affiliates and any control persons of such Initial Purchaser shall be designated in writing by Credit Suisse and any such separate firm for the Company, the Guarantors, their respective directors, officers and any control persons of the Company and the Guarantors shall be designated in writing by the Company. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes (i) an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) Contribution.If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchasers on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors on the one hand and the Initial Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering of Securities (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Initial Purchasers from the Company under this Agreement. The relative fault 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 and the Guarantors or the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages which such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Initial Purchasers’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint.

The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7(d) were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 7(d).

8. Termination. This Agreement may be terminated in the absolute discretion of Credit Suisse, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) any change in United States or international financial, political or economic conditions or currency exchange rates or exchange controls the effect of which is such as to make it, in the judgment of Credit Suisse, impractical to proceed with the offering, sale or delivery of or to enforce contracts for the sale of the Securities, whether in the primary market or in respect of dealings in the secondary market, (ii) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange, the American Stock Exchange, the Nasdaq National Market or the over-the-counter market; (iii) trading of any securities issued or guaranteed by the Company or any of the Guarantors shall have been suspended on any exchange or in any over-the-counter market; (iv) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; (v) any major disruption of settlements of securities, or payment or clearance services in the United States or any other country where such securities are listed or (vi) there shall have occurred any outbreak or escalation of hostilities or any calamity or crisis, either within or outside the United States, that, in the judgment of Credit Suisse, makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Final Offering Circular.

9. Defaulting Initial Purchaser.

(a) If, on the Closing Date, any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Final Offering Circular or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Final Offering Circular that effects any such changes. As used in this Agreement, the term “Initial Purchaser” 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 9, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that

remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder plus such Initial Purchaser’s prorata share (based on the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company or the Guarantors, except that the Company and each of the Guarantors will continue to be liable for the payment of expenses as set forth in Section 10 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 Initial Purchaser of any liability it may have to the Company, the Guarantors or any non-defaulting Initial Purchaser for damages caused by its default.

10. Payment of Expenses.

(b) If (i) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers or (ii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement other than a termination pursuant to Section 8(i), 8(iii) or 8(iv), the Company

and each of the Guarantors jointly and severally agree to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby.

11. 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 any controlling persons referred to herein, and the affiliates, officers, employees, agents, partners, members and directors of each Initial Purchaser 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 Securities from any Initial Purchaser shall be deemed to be a successor merely by reason of such purchase.

12. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Guarantors and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company, the Guarantors or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities 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, the Guarantors or the Initial Purchasers.

In connection with offers and sales of Securities outside the United States:

(a) Each Initial Purchaser acknowledges that the Securities have not been registered under the Securities Act and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except pursuant to an exemption from, or in transactions not subject to, the registration requirements of the Securities Act.

(b) Each Initial Purchaser, severally and not jointly, represents, warrants and agrees that:

(i) Such Initial Purchaser has offered and sold the Securities, and will offer and sell the Securities, (A) as part of their distribution at any time and (B) otherwise until 40 days after the later of the commencement of the offering of the Securities and the Closing Date, only in accordance with Regulation S under the Securities Act (“Regulation S”) or Rule 144A or any other available exemption from registration under the Securities Act.

(ii) None of such Initial Purchaser or any of its affiliates or any other person acting on its or their behalf has engaged or will engage in any directed selling efforts with respect to the Securities, and all such persons have complied and will comply with the offering restrictions requirement of Regulation S.

“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the commencement of the offering of the Securities and the date of original issuance of the Securities, except in accordance with Regulation S or Rule 144A or any other available exemption from registration under the Securities Act. Terms used above have the meanings given to them by Regulation S.”

(iv) Such Initial Purchaser has not and will not enter into any contractual arrangement with any distributor with respect to the distribution of the Securities, except with its affiliates or with the prior written consent of the Company.

Terms used in paragraph (a) and this paragraph (b) and not otherwise defined in this Agreement have the meanings given to them by Regulation S.

(c) In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), each initial purchaser has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant Implementation Date”) it has not made and will not make an offer of Notes which are the subject of the offering contemplated by this Offering Circular to the public in that Relevant Member State other than:

In addition, we have participated in conferences with officers and other representatives of the Obligors, the independent registered public accounting firm and the independent reserve engineers for the Obligors, your counsel and your representatives at which the contents of the Time of Sale Information and the Final Offering Circular and related matters were discussed and, although we have not independently verified and are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Time of Sale Information and the Final Offering Circular (except as and to the extent set forth in paragraphs 6 and 7 above), on the basis of the foregoing (relying with respect to factual matters to the extent we deem appropriate upon statements by officers and other representatives of the Obligors), no facts have come to our attention that have led us to believe that (i) the Time of Sale Information, as of 1:25 p.m., New York Time, on April 18, 2012 (which you have informed us is a time prior to the time of the first sale of the Initial Securities by any Initial Purchaser), contained an untrue statement of a material fact or omitted to state any material fact necessary to make the

statements therein, in light of the circumstances under which they were made, not misleading, or (ii) the Final Offering Circular, as of its date and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, it being understood that we express no opinion, statement or belief in this letter with respect to (i) the historical financial statements and related schedules, including the notes and schedules thereto and the auditor’s reports thereon and (ii) any other reserve, financial or accounting data, included in, or excluded from, the Final Offering Circular or the Time of Sale Information.

We express no opinion as to the laws of any jurisdiction other than (i) applicable laws of the State of Oklahoma, (ii) applicable laws of the United States of America, (iii) certain other specified laws of the United States of America to the extent referred to specifically herein, (iv) the DGCL and (v) the DLLCA. References herein to “applicable laws” mean those laws, rules and regulations that, in our experience, are normally applicable to transactions of the type contemplated by the Transaction Documents, without our having made any special investigation as to the applicability of any specific law, rule or regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided however, that such references to “applicable laws” (including without limitation those appearing in paragraphs 4 and 5 above) do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, securities, tax, insurance or antitrust, laws, rules or regulations.

Our opinions expressed herein are subject to the following additional assumptions and qualifications:

(i) The opinions set forth in paragraph 1 above as to the valid existence and good standing of the Issuer and the other entities mentioned in such paragraph are based solely upon our review of certificates and other communications from the appropriate public officials.

(ii) In rendering the opinions set forth in paragraph 4 above regarding Applicable Agreements, we do not express any opinion, however, as to whether the execution or delivery by the Obligors of the Transaction Documents, or the incurrence or performance by any of the Obligors of its obligations thereunder, will constitute a violation of, or a default under or as a result of, any covenant, restriction or provision, in each case with respect to any financial ratio or test or any aspect of the financial condition or results of operation of any of the Obligors.

(iii) The opinion set forth in paragraph 7 above with respect to United States federal income tax considerations is based upon our interpretations of current United States federal income tax law, including court authority and existing final and temporary U.S. Treasury regulations, which are subject to change both prospectively and retroactively, and upon the assumptions and qualifications discussed herein. We note that such opinion represents merely our best legal judgment on the matters presented and that others may disagree with our conclusion. Such opinion is not binding upon the Internal Revenue Service or courts, and there is no guarantee that the Internal Revenue Service will not successfully challenge our conclusions. No assurance can be given that future legislative, judicial or administrative changes, on either a prospective or retroactive basis, would not adversely affect the accuracy of our conclusions.

(iv) Treasury Circular 230 Disclosure. This disclosure is provided to comply with Treasury Circular 230. The opinion set forth in paragraph 7 of this letter is not intended or written to be used, and cannot be used, by any person for the purpose of avoiding tax penalties that may be imposed on the person. Such opinion was written to support the promoting, marketing or recommending of the transactions or matters addressed by this written advice, and the taxpayer should seek advice based on the taxpayer’s particular circumstances from an independent tax advisor. No limitation has been imposed by our firm on disclosure of the tax treatment or tax structure of the transaction.

(v) Our opinions in paragraphs 8, 9, 10, 11, 12 and 13 above may be:

(1) limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or transfer or other similar laws relating to or affecting the rights of creditors generally; and

(2) subject to the application of general principles of equity (regardless of whether considered in a proceeding in equity or at law), including, without limitation, the possible unavailability of specific performance, injunctive relief or any other equitable remedy and concepts of materiality, reasonableness, good faith and fair dealing.

(vi) With respect to our opinions in paragraphs 8, 9, 10, 11, 12 and 13, the Transaction Documents state that they are governed by the laws of the State of New York. Section 162 of Title 15 of the Oklahoma Statutes provides as follows:

A contract is to be interpreted according to the law and usage of the place where it is to be performed, or, if it does not indicate a place of performance, according to the law and usage of the place where it is made.

In addition to the general choice of law rule stated above, 12A Okla. Stat. § 1-301(1) states as follows:

Except as provided hereafter in this section, when a transaction bears a reasonable relation to this state and also to another state or nation, the parties may agree that the law either of this state or of such other state or nation shall govern their rights and duties. . .

The Oklahoma courts have held in cases construing choice of law provisions in promissory notes that an express provision by the parties designating a place of performance or providing a specific choice of law will be given effect if the designated state bears a reasonable relation to the transaction, unless to give it effect would violate the public policy of Oklahoma. Although we have found no Oklahoma cases specifically addressing the choice of law applicable to a note purchase agreement or a guaranty, we believe that, based on such decisions, an Oklahoma court would give effect to the choice of law provisions in the Transaction Documents that call for the application of New York law as long as Oklahoma public policy is not violated.

(vii) We express no opinion as to the effect of the laws of any jurisdiction in which any holder of any Initial Security or Exchange Security is located (other than the State of Oklahoma) that limit the interest, fees or other charges such holder may impose for the loan or use of money or other credit.

(viii) We express no opinion as to the validity, binding effect or enforceability of Section 4.9 of the Indenture or the first two sentences of Section 7.7 of the Indenture.

(ix) We express no opinion as to the validity, effect or enforceability of any provisions:

(1) purporting to establish particular notice periods or actions as “reasonable,” to establish evidentiary standards or limitations periods for suits or proceedings to enforce such documents or otherwise, to establish certain determinations (including determinations of contracting parties and judgments of courts) as conclusive or conclusive absent manifest error, to commit the same to the discretion of any Person or permit any Person to act in its sole judgment or to waive rights to notice (including, without limitation, notice of acceleration, demands, defenses, counterclaims or setoffs);

(2) providing that the assertion or employment of any right or remedy shall not prevent the concurrent assertion or employment of any other right or remedy, or that each and every remedy shall be cumulative and in addition to every other remedy or that any delay or omission to exercise any right or remedy shall not impair any other right or remedy or constitute a waiver thereof;

(3) relating to severability or separability;

(4) purporting to limit the liability of, or to exculpate, any Person, including without limitation any provision that purports to waive liability for violation of securities laws;

(5) that constitute an agreement to agree in the future on any matter;

(6) that relate to indemnification, contribution or reimbursement obligations to the extent any such provisions (A) would purport to require any Person to provide indemnification, contribution or reimbursement in respect of the negligence, recklessness, willful misconduct or unlawful or wrongful behavior of any Person, (B) violate any law, rule or regulation (including any federal or state securities law, rule or regulation) or (C) are determined to be contrary to public policy;

(7) purporting to establish any obligation of any party as absolute or unconditional regardless of the occurrence or non-occurrence or existence or nonexistence of any event or other state of facts;

(8) purporting to obligate any party to conform to a standard that may not be objectively determinable or employing items that are vague or have no commonly accepted meaning in the context in which used;

(9) purporting to require the payment of liquidated damages, premiums, additional interest or similar amounts, however denominated, for failure to timely comply with obligations under the Registration Rights Agreement; or

(10) purporting to require that all amendments, waivers and terminations be in writing or the disregard of any course of dealing or usage of trade.

(x) In making our examination of executed documents, we have assumed (except to the extent that we expressly opine above) (1) the valid existence and good standing of each of the parties thereto, (2) that such parties had the power and authority, corporate, partnership, limited liability company or other, to enter into and to incur and perform all their obligations thereunder, (3) the due authorization by all requisite action, corporate, partnership, limited liability company or other, and the due execution and delivery by such parties of such documents and (4) to the extent such documents purport to constitute agreements, that each of such documents constitutes the legal, valid and binding obligation of each party thereto, enforceable against such party in accordance with its terms. In this paragraph (x), all references to parties to documents shall be deemed to mean and include each of such parties, and each other person (if any) directly or indirectly acting on its behalf.

(xi) Except to the extent that we expressly opine above, we have assumed that the execution and delivery of the Transaction Documents, and the incurrence and performance of the obligations thereunder of the parties thereto do not and will not contravene, breach, violate or constitute a default under (with the giving of notice, the passage of time or otherwise) (1) the certificate or articles of incorporation, certificate of formation, charter, bylaws, limited liability company agreement, limited partnership agreement or similar organic document of any such party, (2) any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument, (3) any statute, law, rule, or regulation, (4) any judicial or administrative order or decree of any governmental authority, or (5) any consent, approval, license, authorization or validation of, or filing, recording or registration with, any governmental authority, in each case, to which any party to the Transaction Documents or any of its subsidiaries or any of their respective properties may be subject, or by which any of them may be bound or affected. Further, we have assumed the compliance by each such party, other than the Obligors, with all laws, rules and regulations applicable to it, as well as the compliance by the each of the Obligors, and each other person (if any) directly or indirectly acting on its behalf, with all laws, rules and regulations that may be applicable to it solely by virtue of the particular nature of the business conducted by it or any goods or services produced or rendered by it or property owned, operated or leased by it, or any other facts pertaining specifically to it. In this paragraph (xi), all references to parties to the Transaction Documents, other than the first such reference, shall be deemed to mean and include each of such parties, and each other person (if any) directly or indirectly acting on its behalf.

(xii) Without limiting the generality of our qualification in clause (1) of paragraph (v) above, we express no opinion as to the applicability or effect of any preference, fraudulent transfer or conveyance, or similar law on the Transaction Documents or any transactions contemplated thereby or any opinion expressed herein.

(xiii) Except to the extent that we expressly opine above, we have assumed that no authorization, consent or other approval of, notice to or registration, recording or filing with any court, governmental authority or regulatory body (other than routine informational filings, filings under the Securities Act and filings under the Securities Exchange Act of 1934, as amended) is required to authorize, or is required in connection with the transactions contemplated by the Transaction Documents, the execution or delivery of thereof by or on behalf of any party thereto or the incurrence or performance by any of the parties thereto of its obligations thereunder.

(xiv) The opinion expressed in paragraph 15 above is given in reliance upon facts set forth in the Opinion Support Certificate.

(xv) We advise you that certain of the guaranty and surety waivers contained in the Indenture may be unenforceable in whole or in part.

(xvi) We understand that you are receiving a separate opinion letter dated the date hereof from Xxxxxx X. Xxxxx XX, Esq., General Counsel of the Issuer. We (1) have assumed the accuracy of the opinions and statements expressed therein and (2) assume no responsibility for such opinions and statements.

(xvii) We have assumed that the sale of the Initial Securities pursuant to Regulation S under the Securities Act is not part of a plan or scheme to evade the registration provisions of the Securities Act.

This opinion is being furnished only to you in connection with the sale of the Initial Securities under the Purchase Agreement occurring today and is solely for your benefit and is not to be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by any other Person, including any purchaser of any Initial Securities or Exchange Securities from you and any subsequent purchaser of any Initial Securities or Exchange Securities, without our express written permission.

ANNEX D-2

Form of Opinion of Xxxxxx X. Xxxxx XX, Esq., General Counsel of the Company

Ladies and Gentlemen:

This legal opinion is provided to you pursuant to Section 6(g) of the Purchase Agreement, dated April 18, 2012 (the “Purchase Agreement”), between (i) Chaparral Energy, Inc., a Delaware corporation (the “Company”), (ii) the subsidiaries of the Company named therein as parties thereto and listed in Schedule 2 thereto as guarantors (collectively, the “Guarantors”) and (iii) Credit Suisse Securities (USA) LLC as representative for the Initial Purchasers listed in Schedule 1 to the Purchase Agreement (the “Initial Purchasers”) relating to the issuance and sale by the Company of $400,000,000 aggregate principal amount of 7.625% Senior Notes due 2022 (the “Securities”). Capitalized terms used herein, which are not otherwise defined, shall have the same meaning assigned to such term under the Purchase Agreement.

In my capacity as counsel to the Company, I, or attorneys over whom I exercise supervision, have examined the preliminary offering circular dated April 18, 2012 (the “Preliminary Offering Circular”, as supplemented by the Pricing Supplement dated April 18, 2012 (the “Pricing Supplement” and, together with the Preliminary Offering Circular, the “Time of Sale Information”) and the final offering circular dated April 18, 2012 related to the offering and the sale of the Securities (the “Final Offering Circular”). In addition, I, or attorneys over whom I exercise supervision, have examined the originals, or copies identified to our satisfaction, of such corporate records of the Company and its subsidiaries, including the Guarantors, certificates of public officials, officers of the Company and its subsidiaries, including the Guarantors, and other persons and such other documents, agreements and instruments as I have deemed necessary as a basis for the opinions hereinafter expressed.

Based on the foregoing, I am of the opinion that:

1. The Company has been duly qualified as a foreign corporation to transact business and is in good standing in the State of Oklahoma.

2. The Guarantors are organized in the states set opposite their names on Schedule 2 of the Purchase Agreement (the “Applicable Guarantors,” and each an “Applicable Guarantor”) and each has been duly formed, is validly existing as a corporation or limited liability company, as the case may be, in good standing under the laws of its respective state, and has the corporate or limited liability company power and authority to own, lease and operate its properties and to conduct its business as described in the Time of Sale Information and the Final Offering Circular.

3. Each of the Purchase Agreement, the Registration Rights Agreement, the Indenture and the Securities, and the issuance and sale of the Securities pursuant to the Purchase Agreement and the Indenture, has been duly authorized by the Sole Member of the Applicable Guarantors or in the case of Green Country Supply, Inc., its Board of Directors, and each of the Purchase Agreement, the Registration Rights Agreement and the Indenture, including the guarantee of the Securities and Exchange Securities pursuant to the Indenture, has been validly executed and delivered by each of the Applicable Guarantors.

4. The execution, delivery and performance of the Purchase Agreement, the Registration Rights Agreement, the Indenture and the Securities by the Company and the Guarantors, the compliance by the Company and the Guarantors with all the provisions thereof and the consummation of the transactions contemplated hereby and thereby will not, to my knowledge, (A) violate any indenture, loan agreement, mortgage, lease or other agreement or instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor or their respective property is bound or (B) violate or conflict with any judgment, order or decree of any court or governmental body or agency having jurisdiction over the Company or any Guarantor or their respective property, except in each case, for such violations as would not have a Material Adverse Effect.

5. To my knowledge after due inquiry, there are no legal or governmental proceedings required to be described in the Time of Sale Information and the Final Offering Circular which are not described as required or of any contracts or documents of a character required to be described in the Time of Sale Information and the Final Offering Circular which are not described as required, and in each case insofar as such descriptions constitute summaries of the legal matters, documents or proceedings referred to in the Time of Sale Information and the Final Offering Circular, fairly present as of the date of the Purchase Agreement the information disclosed in the Time of Sale Information and the Final Offering Circular in all material aspects, it being understood that I express no opinion as to the financial statements or schedules or other financial data contained in the Time of Sale Information and the Final Offering Circular.

The opinions expressed herein are limited to the federal laws of the United States and, to the extent relevant hereto, the laws of the State of Oklahoma, as currently in effect. I assume no obligation to supplement this opinion if any applicable laws change after the date hereof or if I become aware of any facts that might change the opinions expressed herein after the date hereof.

This opinion is given as of the date hereof and is solely for the benefit of the Initial Purchasers and the Trustee in connection with the transactions contemplated by the Purchase Agreement. This opinion may be relied upon by McAfee Xxxx A Professional Corporation in connection with their opinion rendered in connection with the transactions contemplated by the Purchase Agreement. This opinion may not be relied upon for any other purpose or relied upon by any other person for any purpose without my prior written consent.
