7. Indemnification and Contribution.

(a) Indemnification of the Initial Purchasers. The Company and each of the Subsidiary 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 such Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, 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 caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use therein.

(b) Indemnification of the Company. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each of the Subsidiary Guarantors, each of their respective directors and officers and each person, if any, who controls the Company or any Subsidiary Guarantor 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 Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives 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 there is no such information.

(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 paragraphs (a) and (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 paragraphs (a) and (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. 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 and the Subsidiary Guarantors, their respective directors and officers and any control persons of the Company and the Subsidiary 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 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) 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 Subsidiary 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 Subsidiary 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 Subsidiary 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, bear to the aggregate offering price of the Securities. The relative fault of the Company and the Subsidiary 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 Subsidiary 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 Subsidiary 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 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 which may otherwise be available to any Indemnified Person at law or in equity.

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

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date there shall have occurred (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the NASDAQ; (ii) a suspension or material limitation in trading in the Company’s securities on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) an outbreak or escalation of hostilities or acts of terrorism involving the United States or a declaration by the United States of a national emergency or war; or (v) any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in the judgment of the Representatives 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 ▇▇▇▇▇▇▇▇▇▇.

▇▇

▇▇. 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 Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to 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 10, 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 10 shall be without liability on the part of the Company, except that the Company and each of the Subsidiary Guarantors will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

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

11. Payment of Expenses.

(b) If (i) this Agreement is terminated pursuant to Section 9 (other than pursuant to clause (v) of Section 9 if the Company and the Initial Purchasers subsequently enter into another agreement for the Initial Purchasers to purchase the same or substantially similar securities of the Company), (ii) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Company and each of the Subsidiary Guarantors jointly and severally agree to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the reasonable fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby.

Schedule 1

Annex A

[Form of Opinion of Counsel for the Company]

(a) The Company is validly existing and in good standing as a corporation under the laws of the State of Delaware with all requisite corporate power and authority to own its properties and conduct its business in all material respects as described in the Time of Sale Information and the Offering Memorandum.

(b) Each of the Subsidiary Guarantors is validly existing as a corporation or limited liability company, as applicable, and in good standing under the laws of the State of Delaware; each of the Subsidiary Guarantors has all requisite corporate or limited liability company power and authority to own its respective properties and to conduct its respective business, in all material respects as described in the Time of Sale Information and the Offering Memorandum.

(c) The Company and each of the Subsidiary Guarantors listed on Schedule 1 of such opinion are (i) duly qualified or licensed to do business as a foreign corporation or limited liability company, as applicable, in each jurisdiction listed across from each such entity’s name in column A of Schedule 1 of such opinion and (ii) in good standing in each jurisdiction listed across from each such entity’s name in column B of Schedule 1 of such opinion, [other than those jurisdictions in which good standing is not a relevant concept for such entity and, if verbal or written confirmation of good standing is not available from New York by closing, may omit New York from such opinion].

(d) The documents incorporated by reference in the Time of Sale Information and the Offering Memorandum or any further amendment or supplement thereto made by the Company prior to the Closing Date (except for (a) the financial statements and related schedules thereto, including the notes thereto and the independent registered public accounting firm’s report thereon, (b) the other financial and statistical data that is included or incorporated by reference therein or omitted therefrom and (c) the oil and gas reserve reports and related reserve information contained or incorporated by reference therein or omitted therefrom, in each case as to which we express no opinion), when they were filed with the Commission, appear on their face to be appropriately responsive in all material respects with the requirements of the Securities Act or the Exchange Act and the rules and regulations of the Commission thereunder.

(e) The execution, delivery and performance of the Purchase Agreement, the Registration Rights Agreement, the Indenture, the Securities and the Exchange Securities by the Company and the Subsidiary Guarantors, as applicable, and the consummation by the Company and the Subsidiary Guarantors of the transactions contemplated thereby and the issuance of the Securities by the Company will not (A) result in a violation of any provisions of the Charter or Bylaws or similar organizational documents of the Company or any Subsidiary Guarantor, (B) breach or result in a default under any Applicable Contract, or (C) assuming compliance with all applicable state securities laws and assuming the accuracy of the representations and warranties of the Initial Purchasers contained in the

A-1

Purchase Agreement, result in a violation of any federal or Texas or Delaware state law, regulation or rule or, to our knowledge and without having investigated governmental records or court dockets, any decree, judgment or order applicable to the Company or any of the Subsidiary Guarantors, except, in the case of clause (B) and (C), for such breaches, defaults or violations that would not, individually or in the aggregate, result in a Material Adverse Effect and, in the case of clause (C), such counsel need express no opinion with respect to the anti-fraud provisions of federal securities laws or with respect to state securities laws or Blue Sky laws.

(f) The Purchase Agreement has been duly authorized, executed and delivered by the Company and the Subsidiary Guarantors; and the Registration Rights Agreement has been duly authorized, executed and delivered by the Company and each of the Subsidiary Guarantors and, when duly executed and delivered by the other parties thereto, will constitute a valid and legally binding agreement of the Company and each of the Subsidiary Guarantors enforceable against the Company and each of the Subsidiary Guarantors in accordance with its terms except that (A) the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, or by general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought and (B) the rights to indemnity and contribution may be limited by applicable law, rule, regulation or judicial determination or interpretation of the Commission.

(g) The Indenture has been duly authorized, executed and delivered by the Company and the Subsidiary Guarantors and, assuming the due authorization, execution and delivery thereof by the Trustee, constitutes a legal, valid and binding agreement of the Company and the Subsidiary Guarantors, enforceable against the Company and the Subsidiary Guarantors in accordance with its terms except that (A) the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, or by general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought and (B) the rights to indemnity and contribution may be limited by applicable law, rule, regulation or judicial determination or interpretation of the Commission; and the Indenture conforms in all material respects with the requirements of the Trust Indenture Act and the rules and regulations of the Commission applicable to an indenture that is qualified thereunder.

(h) The Guarantees, as defined in the Indenture, have been duly authorized, executed and delivered by the Subsidiary Guarantors, and, assuming the due authorization, execution and delivery of the Securities by the Trustee and upon payment for and delivery of the Notes in accordance with the Purchase Agreement, each Guarantee will constitute a legal, valid and binding agreement of each Subsidiary Guarantor, enforceable against each such Subsidiary Guarantor in accordance with its terms except that (A) the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, or by general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought and (B) the rights to indemnity and contribution may be limited by applicable law, rule, regulation or judicial determination or interpretation of the Commission.

A-2

(i) The Securities have been duly authorized by the Company, and when executed and duly authenticated in accordance with the terms of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of the Purchase Agreement, (A) will constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except that (i) the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, or by general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought, and (ii) the rights to indemnity and contribution may be limited by applicable law, rule, regulation or judicial determination or interpretation of the Commission, and (B) will be entitled to the benefits of the Indenture.

(j) The Exchange Guarantees, as defined in the Registration Rights Agreement, have been duly authorized by the Subsidiary Guarantors, and, when duly executed and delivered as contemplated by the Registration Rights Agreement and assuming the due execution and delivery of the Indenture by the Trustee and the authentication and delivery of the Exchange Securities by the Trustee, will constitute a legal, valid and binding agreement of each Subsidiary Guarantor, enforceable against each such Subsidiary Guarantor in accordance with its terms except that (A) the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, or by general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought and (B) the rights to indemnity and contribution may be limited by applicable law, rule, regulation or judicial determination or interpretation of the Commission.

A-3

(l) No approval, authorization, consent or order of or filing with any federal, Texas or Delaware governmental or regulatory commission, board, body, authority or agency is required in connection with the issuance and sale by the Company of the Securities as contemplated in the Purchase Agreement, other than as may be required under the securities or Blue Sky laws of the various jurisdictions in which the Securities are being resold by the Initial Purchasers.

(m) The statements set forth in the Time of Sale Information and the Offering Memorandum under the caption “Description of notes” (when taken together with the terms of the Securities set forth in the Time of Sale Information), insofar as they purport to constitute a summary of the terms of the Securities, are accurate summaries in all material respects; and the statements set forth in the Time of Sale Information and the Offering Memorandum under the caption “Certain United States federal income and estate tax considerations,” insofar as they purport to constitute summaries of matters of law or regulation or legal conclusions, are accurate summaries in all material respects.

(n) Neither the Company nor any of the Subsidiary Guarantors is, or after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Time of Sale Information and the Offering Memorandum will be, required to register as an “investment company” as defined in the Investment Company Act of 1940, as amended.

(o) Assuming (i) the accuracy of the representations, warranties and agreements of the Company, the Subsidiary Guarantors and the Initial Purchasers contained in the Purchase Agreement; (ii) the compliance with the Initial Purchasers of the covenants and agreements set forth in the Purchase Agreement; and (iii) the compliance by the Initial Purchasers with the offer and transfer restrictions described in the Offering Memorandum under the caption “Transfer restrictions”, it is not necessary, in connection with the issuance and sale of the Securities to the Initial Purchasers and the offer, resale and delivery of the Securities by the Initial Purchasers in the manner contemplated by the Purchase Agreement, the Time of Sale Information and the Offering Memorandum, to register the Securities under the Securities Act or to qualify the Indenture under the Trust Indenture Act; provided, however, we express no opinion as to any subsequent resale of the Securities.

(p) Based upon our participation in conferences with officers and other representatives of the Company, representatives of the independent public accountants of the Company and representatives of the Initial Purchasers and their counsel at which the contents of the Time of Sale Information and the Offering Memorandum and any amendment and supplement thereto and related matters were discussed and without any additional inquiry or due diligence (except as necessary to express the opinions set forth above), although we have not conducted any independent investigations with regard to the information in the Time of Sale Information and the Offering Memorandum 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 to the extent stated in paragraph (m) above), no facts have come to our attention which lead us to believe that the Time of Sale Information, at the Time of

A-4

Sale (which such counsel may assume to be 2:50 p.m. Eastern time on the date of the Purchase Agreement) contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or that the Offering Memorandum or any amendment or supplement thereto as of its date and the Closing Date contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (except for (a) the financial statements and related schedules thereto, including the notes thereto, and the independent registered public accounting firm’s report thereon, (b) the other financial and statistical data that is included or incorporated by reference therein or omitted therefrom and (c) the oil and gas reserve reports and related reserve information contained or incorporated by reference therein.
