7. Indemnification and Contribution.

(a) Indemnification of the Initial Purchasers. The Company and each of the Guarantors jointly and severally agree to indemnify and hold harmless each Initial Purchaser, its affiliates, directors and officers and each person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) such Initial Purchaser, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto) or any omission or alleged omission to state in the Time of Sale Information or the Offering Memorandum a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Initial Purchaser consists of the information described as such in subsection (b) below.

(b) Indemnification of the Company. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each of the Guarantors, their respective directors and officers and each person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the Company or any of the Guarantors to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information furnished to the Company in writing by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication

or the Offering Memorandum (or any amendment or supplement thereto), it being understood and agreed that the only such information consists of the following: the information contained in the fourth sentence of the eleventh paragraph and the thirteenth paragraph under the caption “Plan of distribution” in the Preliminary Offering Memorandum and the Offering Memorandum.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related 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 Persons, 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 affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by ▇.▇. ▇▇▇▇▇▇ Securities LLC and any such separate firm for the Company, the Guarantors, their respective directors and officers and any control persons of the Company and the Guarantors shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled

with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

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

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

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

8. Termination. This Agreement may be terminated in the absolute discretion of ▇.▇. ▇▇▇▇▇▇ Securities LLC, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange, the American Stock Exchange, the Nasdaq National Market or the over-the-counter market; (ii) 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; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of ▇.▇. ▇▇▇▇▇▇ Securities LLC, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum.

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 Offering Memorandum 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 Offering Memorandum 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 pro rata 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.

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 Offering Memorandum 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 Offering Memorandum (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 p.m. on September , 2010 (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 Offering Memorandum, 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, (ii) any other reserve, financial or accounting data, included in, or excluded from, the Offering Memorandum or the Time of Sale Information, and (iii) the exclusion from the Time of Sale Information of any pricing information (and directly related disclosure) included in the Offering Memorandum.

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 ▇▇▇▇▇▇ ▇. ▇▇▇▇▇ ▇▇, 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. The opinions expressed herein are as of the date hereof only and are based on laws, orders, contract terms and provisions, and facts as of such date, and we disclaim any obligation to update this opinion letter after such date or to advise you of changes of facts stated or assumed herein or any subsequent changes in applicable law.

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 Memorandum dated September [ ], 2010 (the “Preliminary Offering Memorandum”, as supplemented by the Pricing Supplement dated September[ ], 2010 (the “Pricing Supplement” and, together with the Preliminary Offering Memorandum, the “Time of Sale Information”) and the final Offering Memorandum dated September [ ], 2010 related to the offering and the sale of the Securities (the “Offering Memorandum”). 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 Offering Memorandum.

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 Offering Memorandum 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 Offering Memorandum 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 Offering Memorandum, fairly present as of the date of the Purchase Agreement the information disclosed in the Time of Sale Information and the Offering Memorandum 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 Offering Memorandum.

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.

16. Registration Under the Securities Act. (a) To the extent not prohibited by any applicable law or applicable interpretations of the Staff, the Company and the Guarantors shall

use their commercially reasonable efforts to (i) cause to be filed an Exchange Offer Registration Statement covering an offer to the Holders to exchange all the Registrable Securities for like principal amount of Exchange Securities and (ii) have such Registration Statement remain effective until 90 days after the closing of the Exchange Offer. The Company and the Guarantors shall commence the Exchange Offer promptly after the Exchange Offer Registration Statement is declared effective by the SEC and use their commercially reasonable efforts to complete the Exchange Offer not later than 60 days after such effective date.

The Company and the Guarantors shall commence the Exchange Offer by mailing the related Prospectus, appropriate letters of transmittal and other accompanying documents to each Holder stating, in addition to such other disclosures as are required by applicable law, substantially the following:

(i) that the Exchange Offer is being made pursuant to this Agreement and that all Registrable Securities validly tendered and not properly withdrawn will be accepted for exchange;

(ii) the dates of acceptance for exchange (which shall be a period of at least 20 Business Days from the date such notice is mailed) (the “Exchange Dates”);

(iii) that any Registrable Security not tendered will remain outstanding and continue to accrue interest but will not retain any rights under this Agreement;

(iv) that any Holder electing to have a Registrable Security exchanged pursuant to the Exchange Offer will be required to surrender such Registrable Security, together with the appropriate letters of transmittal, to the institution and at the address (located in the Borough of Manhattan, The City of New York) and in the manner specified in the notice, prior to the close of business on the last Exchange Date; and

(v) that any Holder will be entitled to withdraw its election, not later than the close of business on the last Exchange Date, by sending to the institution and at the address (located in the Borough of Manhattan, The City of New York) specified in the notice, a telegram, telex, facsimile transmission or letter setting forth the name of such Holder, the principal amount of Registrable Securities delivered for exchange and a statement that such Holder is withdrawing its election to have such Securities exchanged.

As a condition to participating in the Exchange Offer, a Holder will be required to represent to the Company and the Guarantors that (i) any Exchange Securities to be received by it will be acquired in the ordinary course of its business, (ii) at the time of the commencement of the Exchange Offer it has no arrangement or understanding with any Person to participate in the distribution (within the meaning of the Securities Act) of the Exchange Securities in violation of the provisions of the Securities Act, (iii) it is not an “affiliate” (within the meaning of Rule 405 under the Securities Act) of the Company or any Guarantor and (iv) if such Holder is a broker-dealer that will receive Exchange Securities for its own account in exchange for Registrable Securities that were acquired as a result of market-making or other trading activities, then such Holder will deliver a Prospectus in connection with any resale of such Exchange Securities.

As soon as practicable after the last Exchange Date, the Company and the Guarantors shall:

accept for exchange Registrable Securities or portions thereof validly tendered and not properly withdrawn pursuant to the Exchange Offer; and

(vi) deliver, or cause to be delivered, to the Trustee for cancellation all Registrable Securities or portions thereof so accepted for exchange by the Company and issue, and cause the Trustee to promptly authenticate and deliver to each Holder, Exchange Securities equal in aggregate principal amount to the aggregate principal amount of the Registrable Securities surrendered by such Holder.

The Company and the Guarantors shall use their commercially reasonable efforts to complete the Exchange Offer as provided above and shall comply with the applicable requirements of the Securities Act, the Exchange Act and other applicable laws and regulations in connection with the Exchange Offer. The Exchange Offer shall not be subject to any conditions, other than that the Exchange Offer does not violate any applicable law or applicable interpretation of the Staff.

If, during the period the Exchange Offer Registration Statement is effective, an event occurs which makes any statement made in such Exchange Offer Registration Statement or the related Prospectus untrue in any material respect or which requires the making of any changes in such Exchange Offer Registration Statement in order to make the statements therein not misleading or in such Prospectus in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Company and the Guarantors shall use their commercially reasonable efforts to prepare and file with the SEC a supplement or post-effective amendment to the Exchange Offer Registration Statement or the related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Securities, such Prospectus will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Company agrees to notify the Holders and to suspend the exchange of the Registrable Securities as promptly as practicable after the occurrence of such an event, and the Holders hereby agree to suspend such exchange until the Company and the Guarantors have amended or supplemented the Prospectus to correct such misstatement or omission.

(b) In the event that (i) the Company and the Guarantors determine that the Exchange Offer Registration provided for in Section 2(a) above is not available or may not be completed as soon as practicable after the last Exchange Date because it would violate any applicable law or applicable interpretation of the Staff, (ii) the Exchange Offer is not for any other reason completed on or prior to the 270th day after the Closing Date or (iii) any Initial Purchaser shall so request in connection with any offer or sale of Registrable Securities, the Company and the Guarantors shall use their reasonable best efforts to cause to be filed as soon as practicable after such determination, date or request, as the case may be, a Shelf Registration Statement providing for the sale of all the Registrable Securities by the Holders thereof and to have such Shelf Registration Statement declared effective by the SEC.

In the event that the Company and the Guarantors are required to file a Shelf Registration Statement pursuant to clause (iii) of the preceding sentence, the Company and the Guarantors shall use their commercially reasonable efforts to file and have declared effective by the SEC both an Exchange Offer Registration Statement pursuant to Section 2(a) with respect to all Registrable Securities and a Shelf Registration Statement (which may be a combined Registration Statement with the Exchange Offer Registration Statement) with respect to offers and sales of Registrable Securities held by the Initial Purchasers after completion of the Exchange Offer.

The Company and the Guarantors agree to use their commercially reasonable efforts to keep the Shelf Registration Statement continuously effective until the second anniversary of the Issue Date or such shorter period that will terminate when all the Registrable Securities covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement or cease to be Registrable Securities within the meaning of this Agreement (the “Shelf Effectiveness Period”). The Company and the Guarantors further agree to supplement or amend the Shelf Registration Statement and the related Prospectus if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement or by the Securities Act or by any other rules and regulations thereunder for shelf registration or if reasonably requested by a Holder to correct information relating to such Holder (provided the Majority Holders do not object to such amendment and resulting limitation of use of the Shelf Registration Statement), and to use their commercially reasonable efforts to cause any such amendment to become effective and such Shelf Registration Statement and Prospectus to become usable as soon as thereafter practicable. The Company and the Guarantors agree to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or filed with the SEC.

(c) The Company and the Guarantors shall pay all Registration Expenses in connection with any registration pursuant to Section 2(a) or Section 2(b) hereof. Each Holder shall pay all underwriting discounts and commissions, brokerage commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Registrable Securities pursuant to the Shelf Registration Statement.

(d) An Exchange Offer Registration Statement pursuant to Section 2(a) hereof will not be deemed to have become effective unless it has been declared effective by the SEC. A Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed to have become effective unless it has been declared effective by the SEC or is automatically effective upon filing with the SEC as provided by Rule 462 under the Securities Act.

The Company, each Guarantor and the Initial Purchasers agree that the Holders will suffer damages if the Company or the Guarantors fail to fulfill their respective obligations under Section 2(a) or Section 2(b) hereof and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Company and each Guarantor agree that in the event that:

(i) either the Exchange Offer is not completed or the Shelf Registration Statement, if required hereby, is not declared effective on or prior to the 270th day after the Closing Date (a “Registration Default”); or

(ii) the Shelf Registration Statement, if required hereby, has been declared effective and thereafter either ceases to be effective or the Prospectus contained therein ceases to be usable at any time during the Shelf Effectiveness Period, and such failure to remain effective or usable continues for 30 consecutive days or exists for more than an aggregate of 60 days in any 12-month period (a “Shelf Registration Default”);

then the Company and the Guarantors hereby agree to pay each Holder of Registrable Securities affected thereby, liquidated damages (“Liquidated Damages”). Liquidated Damages will accrue on the affected Registrable Securities and the affected Exchange Securities, as applicable. The rate of Liquidated Damages will be 0.25% per annum of the principal amount of Registrable Securities held by such Holder for the first 90-day period immediately following the occurrence of a Registration Default or Shelf Registration Default, as applicable, increasing by 0.25% per annum with respect to each subsequent 90-day period, up to a maximum of 1.00% per annum, in each case until (x) with respect to a Registration Default, the Exchange Offer is completed or the Shelf Registration Statement, if required hereby, is declared effective by the SEC or a Shelf Registration Statement relating to the Securities has become effective or (y) with respect to a Shelf Registration Default, the Shelf Registration Statement has again been declared effective or the Prospectus again becomes usable.

Notwithstanding the foregoing, (1) the amount of Liquidated Damages payable shall not increase because more than one Registration Default has occurred and is pending and (2) a Holder of Registrable Securities or Exchange Securities who is not entitled to the benefits of the Shelf Registration Statement (i.e., such Holder has not elected to furnish information to the Company in accordance with Section 3(b) hereof) shall not be entitled to Liquidated Damages with respect to a Shelf Registration Default.

Anything herein to the contrary notwithstanding, no Holder who (x) was eligible to exchange such Holder’s outstanding Securities at the time that the Exchange Offer was pending and consummated and (y) failed to validly tender such Securities for exchange pursuant to the Exchange Offer shall be entitled to receive any Liquidated Damages that would otherwise accrue subsequent to the date the Exchange Offer is consummated pursuant to this Section 2(d).

(e) The Company shall notify the Trustee within one Business Day after each date on which an event occurs in respect of which Liquidated Damages are required to be paid. Any amounts of Liquidated Damages due pursuant to this Section 2 will be payable in addition to any other interest payable from time to time with respect to the Registrable Securities in cash semi-annually on the interest payment dates specified in the Indenture (to the holders of record as specified in the Indenture), commencing with the first such interest payment date occurring after any such Liquidated Damages commence to accrue. The amount of Liquidated Damages will be determined in a manner consistent with the calculation of interest under the Indenture.

(f) Without limiting the remedies available to the Initial Purchasers and the Holders, the Company and the Guarantors acknowledge that any failure by the Company or the Guarantors to comply with their obligations under Section 2(a) and Section 2(b) hereof may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company’s and the Guarantors’ obligations under Section 2(a) and Section 2(b) hereof.

(g) The Company represents, warrants and covenants that it (including its agents and representatives) will not prepare, make, use, authorize, approve or refer to any Free Writing Prospectus.

17. Registration Procedures. (a) In connection with their obligations pursuant to Section 2(a) and Section 2(b) hereof, the Company and the Guarantors shall:

(i) prepare and file with the SEC a Registration Statement on the appropriate form under the Securities Act, which form (x) shall be selected by the Company and the Guarantors, (y) shall, in the case of a Shelf Registration, be available for the sale of the Registrable Securities by the Holders thereof and (z) shall comply as to form in all material respects with the requirements of the applicable form and include all financial statements required by the SEC to be filed therewith; and use their commercially reasonable efforts to cause such Registration Statement to become effective and remain effective for the applicable period in accordance with Section 2 hereof;

with the National Association of Securities Dealers, Inc.; and do any and all other acts and things that may be reasonably necessary or advisable to enable each Holder to complete the disposition in each such jurisdiction of the Registrable Securities owned by such Holder; provided that neither the Company nor any Guarantor shall be required to (1) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (2) file any general consent to service of process in any such jurisdiction or (3) subject itself to taxation in any such jurisdiction if it is not so subject;

(vi) use their reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement or, in the case of a Shelf Registration, the resolution of any objection of the SEC pursuant to Rule 401(g)(2), including by filing an amendment to such Shelf Registration Statement on the proper form, at the earliest possible moment and provide immediate notice to each Holder of the withdrawal of any such order or such resolution;

(vii) in the case of a Shelf Registration, furnish to each Holder of Registrable Securities, without charge, at least one conformed copy of each Registration Statement and any post-effective amendment thereto (without any documents incorporated therein by reference or exhibits thereto, unless requested);

(ix) in the case of a Shelf Registration, upon the occurrence of any event contemplated by Section 3(a)(v)(5) hereof, use their commercially reasonable efforts to prepare and file with the SEC a supplement or post-effective amendment to such Shelf Registration Statement or the related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities, such Prospectus will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and the Company and the Guarantors shall notify the Holders of Registrable Securities to suspend use of the Prospectus as promptly as practicable after the occurrence of such an event, and such Holders hereby agree to suspend use of the Prospectus until the Company and the Guarantors have amended or supplemented the Prospectus to correct such misstatement or omission or until the Company notifies the Holders that the sale of the Registrable Securities may be resumed;

(xi) obtain a CUSIP number for all Exchange Securities or Registrable Securities, as the case may be, not later than the effective date of a Registration Statement;

(xv) if reasonably requested by any Holder of Registrable Securities covered by a Shelf Registration Statement, promptly include in a Prospectus supplement or post-effective amendment such information with respect to such Holder as such Holder reasonably requests to be included therein and make all required filings of such Prospectus supplement or such post-effective amendment as soon as the Company has received notification of the matters to be so included in such filing;

(xvi) in the case of a Shelf Registration, enter into such customary agreements and take all such other reasonable actions in connection therewith (including those requested by the Holders of a majority in principal amount of the Registrable Securities being sold) in order to expedite or facilitate the disposition of such Registrable Securities including, but not limited to, an Underwritten Offering and in such connection,

(1) to the extent possible, make such representations and warranties to the Holders and any Underwriters of such Registrable Securities with respect to the business of the Company and its subsidiaries and the Registration Statement, Prospectus and documents incorporated by reference or deemed incorporated by reference, if any, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings and confirm the same if and when requested, (2) obtain opinions of counsel to the Company and the Guarantors (which counsel and opinions, in form, scope and substance, shall be reasonably satisfactory to the Holders and such Underwriters and their respective counsel) addressed to each selling Holder and Underwriter of Registrable Securities, covering the matters customarily covered in opinions requested in underwritten offerings of the type contemplated by this provision, (3) obtain “comfort” letters from the independent certified public accountants of the Company and the Guarantors (and, if necessary, any other certified public accountant of any subsidiary of the Company or any Guarantor, or of any business acquired by the Company or any Guarantor for which financial statements and financial data are or are required to be included in the Registration Statement) addressed to each selling Holder and Underwriter of Registrable Securities (subject, in each case, to the policies and procedures of the independent certified public accountants of the Company and the Guarantors and such other independent certified public accountants regarding the preparation and delivery of such letters), such letters to be in customary form and covering matters of the type customarily covered in “comfort” letters in connection with underwritten offerings of the type contemplated by this provision and (4) deliver such documents and certificates as may be reasonably requested by the Holders of a majority in principal amount of the Registrable Securities being sold or the Underwriters, and which are customarily delivered in underwritten offerings of the type contemplated by this provision, to evidence the continued validity of the representations and warranties of the Company and the Guarantors made pursuant to clause (1) above and to evidence compliance with any customary conditions contained in an underwriting agreement; and

(xvii) so long as any Registrable Securities remain outstanding, cause each Additional Guarantor upon the creation or acquisition by the Company of such Additional Guarantor, to take such action as to permit the Company and the Guarantors to comply with this Agreement, including making such Additional Guarantor a co-registrant of securities under any Registration Statement or Shelf Registration Statement.

(b) In the case of a Shelf Registration Statement, the Company and the Guarantors may require each Holder of Registrable Securities to furnish to the Company such information regarding such Holder and the proposed disposition by such Holder of such Registrable Securities as the Company and the Guarantors may from time to time reasonably request in writing. So long as any Holder fails to furnish such information in a reasonably timely manner after receiving the request, the Company and the Guarantors shall (i) have no obligation under this Agreement to provide for the disposition of such Holder’s Registrable Securities in the Shelf Registration Statement in respect to which such information was requested, (ii) not be required to provide for the disposition of such Holder’s Registrable Securities in any post-effective amendment to such Shelf Registration Statement or any future Shelf Registration Statement that is not otherwise required to be filed and (iii) not be required to pay any liquidated damages to such Holder as provided in Section 2(d) hereof. Each Holder including Registrable Securities in a Shelf Registration

Statement shall agree to furnish promptly to the Company all information regarding such Holder and the proposed distribution by such Holder of such Registrable Securities required to make the information previously furnished to the Company by such Holder not materially misleading.

(c) In the case of a Shelf Registration Statement, each Holder of Registrable Securities agrees that, upon receipt of any notice from the Company or any Guarantor of the happening of any event of the kind described in Section 3(a)(v)(3) or 3(a)(v)(5) hereof, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to the Shelf Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 3(a)(ix) hereof and, if so directed by the Company or any Guarantor, such Holder will deliver to the Company and the Guarantors all copies in its possession, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities that is current at the time of receipt of such notice.

(d) If the Company or any Guarantor shall give any notice pursuant to Section 3(c) hereof to suspend the disposition of Registrable Securities pursuant to a Shelf Registration Statement, the Company and the Guarantors shall extend the period during which such Shelf Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such notice to and including the date when the Holders of such Registrable Securities shall have received copies of the supplemented or amended Prospectus necessary to resume such dispositions. The Company and the Guarantors may give any such notice only twice during any 365-day period and any such suspensions shall not exceed 60 days in the aggregate and there shall not be more than two suspensions in effect during any 365-day period.

(e) The Holders of Registrable Securities covered by a Shelf Registration Statement who desire to do so may sell such Registrable Securities in an Underwritten Offering. In any such Underwritten Offering, the investment bank or investment banks and manager or managers (each an “Underwriter”) that will administer the offering will be selected by the Holders of a majority in principal amount of the Registrable Securities included in such offering.

18. Participation of Broker-Dealers in Exchange Offer. (a) The Staff has taken the position that any broker-dealer that receives Exchange Securities for its own account in the Exchange Offer in exchange for Securities that were acquired by such broker-dealer as a result of market-making or other trading activities (a “Participating Broker-Dealer”) may be deemed to be an “underwriter” within the meaning of the Securities Act and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Securities.

The Company and the Guarantors understand that it is the Staff’s position that if the Prospectus contained in the Exchange Offer Registration Statement includes a plan of distribution containing a statement to the above effect and the means by which Participating Broker-Dealers may resell the Exchange Securities, without naming the Participating Broker-Dealers or specifying the amount of Exchange Securities owned by them, such Prospectus may be delivered by Participating Broker-Dealers to satisfy their prospectus delivery obligation under the Securities Act in connection with resales of Exchange Securities for their own accounts, so long as the Prospectus otherwise meets the requirements of the Securities Act.

(b) In light of the above, and notwithstanding the other provisions of this Agreement, the Company and the Guarantors agree to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement for a period of up to 90 days after the last Exchange Date (as such period may be extended pursuant to Section 3(d) of this Agreement), if requested by the Initial Purchasers or by one or more Participating Broker-Dealers, in order to expedite or facilitate the disposition of any Exchange Securities by Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above. The Company and the Guarantors further agree that Participating Broker-Dealers shall be authorized to deliver such Prospectus during such period in connection with the resales contemplated by this Section 4.

(c) The Initial Purchasers shall have no liability to the Company, any Guarantor or any Holder with respect to any request that they may make pursuant to Section 4(b) above.

19. Indemnification and Contribution. (a) The Company and each Guarantor, jointly and severally, agree to indemnify and hold harmless each Initial Purchaser and each Holder, their respective affiliates, directors and officers and each Person, if any, who controls any Initial Purchaser or any Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Prospectus, any Free Writing Prospectus used in violation of this Agreement or any “issuer information” (“Issuer Information”) filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser, or information relating to any Holder furnished to the Company in writing through JPM or any selling Holder expressly for use therein. In connection with any Underwritten Offering permitted by Section 3, the Company and the Guarantors will also enter into an underwriting agreement pursuant to which the Company and the Guarantors will agree to jointly and severally indemnify the Underwriters, if any, selling brokers, dealers and similar securities industry professionals participating in such Underwritten Offering, their respective affiliates and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any Registration Statement, any Prospectus, any Free Writing Prospectus or any Issuer Information.

(b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantors, the Initial Purchasers and the other selling Holders, the directors of the Company and the Guarantors, each officer of the Company and the Guarantors who signed the Registration Statement and each Person, if any, who controls the Company, the Guarantors, any Initial Purchaser and any other selling Holder within the meaning of Section 15 of the Securities

Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement and any Prospectus.

(c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such Person (the “Indemnified Person”) shall promptly notify the Person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 5 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 5. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 5 that the Indemnifying Person may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related 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 Persons, and that all such reasonable fees and expenses shall be reimbursed as they are incurred. Any such separate firm (x) for any Initial Purchaser, its affiliates, directors and officers and any control Persons of such Initial Purchaser shall be designated in writing by JPM, (y) for any Holder, its directors and officers and any control Persons of such Holder shall be designated in writing by the Majority Holders and (z) in all other cases shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after

receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors from the offering of the Securities and the Exchange Securities, on the one hand, and by the Holders from receiving Securities or Exchange Securities registered under the Securities Act, on the other hand, or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Guarantors on the one hand and the Holders on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Guarantors on the one hand and the Holders on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors or by the Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company, the Guarantors and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 5 were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 5, in no event shall a Holder be required to contribute any amount in excess of the amount by which the total price at which the Securities or Exchange Securities sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

(f) The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

(g) The indemnity and contribution provisions contained in this Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchasers or any Holder or any Person controlling any Initial Purchaser or any Holder, or by or on behalf of the Company or the Guarantors or the officers or directors of or any Person controlling the Company or the Guarantors, (iii) acceptance of any of the Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf Registration Statement.

20. General.

No Inconsistent Agreements. The Company and the Guarantors represent, warrant and agree that (i) the rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of any other outstanding securities issued or guaranteed by the Company or any Guarantor under any other agreement and (ii) neither the Company nor any Guarantor has entered into, or on or after the date of this Agreement will enter into, any agreement that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof.

Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless the Company and the Guarantors have obtained the written consent of Holders of at least a majority in aggregate principal amount of the outstanding Registrable Securities affected by such amendment, modification, supplement, waiver or consent; provided that no amendment, modification, supplement, waiver or consent to any departure from the provisions of Section 5 hereof shall be effective as against any Holder of Registrable Securities unless consented to in writing by such Holder. Any amendments, modifications, supplements, waivers or consents pursuant to this Section 6(b) shall be by a writing executed by each of the parties hereto.

Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, telex, telecopier, or any courier guaranteeing overnight delivery (i) if to a Holder, at the most current address given by such Holder to the Company by means of a notice given in accordance with the provisions of this Section 6(c), which address initially is, with respect to the Initial Purchasers, the address set forth in the Purchase Agreement; (ii) if to the Company or any Guarantor, initially at the Company’s address set forth in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c); and to such other persons at their respective addresses as provided in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c). All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt is acknowledged, if telecopied; and on the next Business Day if timely delivered to an air courier guaranteeing overnight delivery. Copies of all such notices, demands or other communications shall be concurrently delivered by the Person giving the same to the Trustee, at the address specified in the Indenture.

Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors, assigns and transferees of each of the parties, including, without limitation and without the need for an express assignment, subsequent Holders; provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of Registrable Securities in violation of the terms of the Indenture and the Purchase Agreement. If any transferee of any Holder shall acquire Registrable Securities in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all the terms of this Agreement, and by taking and holding such Registrable Securities such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement and such Person shall be entitled to receive the benefits hereof. The Initial Purchasers (in their capacity as Initial Purchasers) shall have no liability or obligation to the Company or the Guarantors with respect to any failure by a Holder to comply with, or any breach by any Holder of, any of the obligations of such Holder under this Agreement.

Third Party Beneficiaries. Each Holder shall be a third party beneficiary to the agreements made hereunder between the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights or the rights of other Holders hereunder.

Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

Headings. The headings in this Agreement are for convenience of reference only, are not a part of this Agreement and shall not limit or otherwise affect the meaning hereof.

Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

Miscellaneous. This Agreement contains the entire agreement between the parties relating to the subject matter hereof and supersedes all oral statements and prior writings with respect thereto. If any term, provision, covenant or restriction contained in this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable or against public policy, the remainder of the terms, provisions, covenants and restrictions contained herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated. The Company, the Guarantors and the Initial Purchasers shall endeavor in good faith negotiations to replace the invalid, void or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, void or unenforceable provisions.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.
