2. Representations and Warranties of the Company and the Subsidiary Guarantors. The Company and each Subsidiary Guarantor, jointly and severally, represents and warrants to, and agrees with, the several Underwriters that:

(i) A registration statement (No. 333-219649) including all materials incorporated by reference therein and a base prospectus, relating to the Offered Securities, has been filed with the Securities and Exchange Commission (the “Commission”) and has become effective. Such registration statement as amended to the date of this Agreement, including all materials incorporated by reference therein and any

prospectus or prospectus supplement deemed or retroactively deemed to be part thereof that has not been superseded or modified, is hereinafter referred to as the “Registration Statement”. “Registration Statement” without reference to a time means the Registration Statement as of the date and time of its filing and effectiveness which time shall be considered the “effective date” of the Registration Statement. For purposes of the previous sentence, information contained in a form of prospectus or prospectus supplement that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B (“Rule 430B”) under the Securities Act of 1933, as amended (the “Act”) shall be considered to be included in the Registration Statement as of the time specified in Rule 430B. “Statutory Prospectus” as of any time means the prospectus included in the Registration Statement immediately prior to that time, including any document incorporated by reference therein and any base prospectus or prospectus supplement deemed to be a part thereof that has not been superseded or modified. For purposes of the preceding sentence, information contained in a form of prospectus (including a prospectus supplement) that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B shall be considered to be included in the Statutory Prospectus as of the actual time that form of prospectus (including a prospectus supplement) is filed with the Commission pursuant to Rule 424(b) (“Rule 424(b)”) under the Act. “Prospectus” means the Statutory Prospectus that discloses the public offering price and other final terms of the Offered Securities and otherwise satisfies Section 10(a) of the Act. “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 under the Act, relating to the Offered Securities in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g) under the Act. “General Use Issuer Free Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors, as evidenced by its form being specified in Schedule C to this Agreement. “Limited Use Issuer Free Writing Prospectus” means any Issuer Free Writing Prospectus that is not a General Use Issuer Free Writing Prospectus. “Applicable Time” means 6:15 p.m. (Eastern time) on the date of this Agreement. Any reference herein to the terms “amend,” “amendment,” or “supplement” with respect to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus shall be deemed to refer to and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations of the Commission (the “Rules and Regulations”) on or after the initial effective date of the Registration Statement, or the date of such Prospectus or Issuer Free Writing Prospectus, as the case may be, and deemed to be incorporated by reference therein.

(ii) On its effective date, the Registration Statement conformed in all material respects to the requirements of the Act and the Rules and Regulations and did not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and on the date of this Agreement and on the Closing Date (as defined herein), the Registration Statement and the Prospectus conform or will conform in all material respects to the requirements of the Act and the Rules and Regulations, and neither of such documents include or will include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the case of the Prospectus, in light of the circumstances under which they were made, not misleading, except that the foregoing does not apply to statements in or omissions from any of such documents based upon written information furnished to the Company by an Underwriter, if any, specifically for use therein, it being understood and agreed that the only such information furnished by an Underwriter consists of the information described as such in Section 8(ii) hereof. The documents incorporated by reference in the Prospectus (the “Company Filed Documents”), when they became effective or were filed with the Commission, as the case may be, conformed in all material respects with the requirements of the Act or the Exchange Act, as applicable, and the Rules and Regulations and when read together with the other information in the General Disclosure Package (as defined herein) did not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statement therein, in light of the circumstances under which it was made, not misleading.

(iii) The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405 under the Act, that initially became effective within three years of the date of this Agreement, and as of the determination date applicable to the Registration Statement (and any amendment thereof) and the offering contemplated hereby, the Company is a “well-known seasoned issuer” (as defined in Rule 405

2

under the Act). If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement, any of the Offered Securities remain unsold by the Underwriters, the Company will, prior to the Renewal Deadline, if it has not already done so and is eligible to do so, file a new automatic shelf registration statement relating to the Offered Securities, in a form satisfactory to the Representative. If the Company is no longer eligible to file an automatic shelf registration statement, the Company will, prior to the Renewal Deadline, file, if it has not already done so, a new shelf registration statement relating to the Offered Securities, in a form satisfactory to the Representative, and will use its best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Offered Securities to continue as contemplated in the expired registration statement relating to the Offered Securities. References herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

(iv) The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to use of the automatic shelf registration statement form.

The Company will take all other action necessary or appropriate to permit the public offering and sale of the Offered Securities to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Company has otherwise become ineligible. References herein to the registration statement relating to the Offered Securities shall include such new registration statement or post-effective amendment, as the case may be.

(iii) If, at any time when a prospectus relating to the Offered Securities is required to be delivered (whether physically or through compliance with Rule 172 under the Act) in connection with sales by the Underwriters or any dealer, any event occurs as a result of which the Prospectus, as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or the Prospectus to comply with the Act, the Company promptly will notify the Underwriters of such event and will promptly prepare and file with the Commission, at its own expense, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Underwriters’ consent to, nor the Underwriters’ delivery to offerees or investors of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

(iv) As soon as practicable, but not later than 16 months, after the date of this Agreement, the Company will make generally available to its security holders an earnings statement covering a period of at least 12 months beginning after the later of (i) the effective date of the registration statement relating to the Offered Securities, (ii) the effective date of the most recent post-effective amendment to the Registration Statement to become effective prior to the date of this Agreement and (iii) the date of the Company’s most recent Annual Report on Form 10-K filed with the Commission prior to the date of this Agreement, which will satisfy the provisions of Section 11(a) of the Act and Rule 158 thereunder.

9

(v) The Company will furnish to the Underwriters copies of the Registration Statement in the form it became effective (including all exhibits) and of all amendments thereto, any related preliminary prospectus, any related preliminary prospectus supplement, and, so long as a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be required to be) delivered under the Act in connection with sales by the Underwriters or any dealer, the Prospectus and all amendments and supplements to such documents, in each case in such quantities as the Underwriters request. The Prospectus shall be so furnished on or prior to 3:00 p.m., New York time, on the business day following the execution and delivery of this Agreement. All other documents shall be so furnished as soon as available. The Company will pay the expenses of printing and distributing to the Underwriters all such documents.

(vi) The Company will arrange for the qualification of the Offered Securities for sale under the laws of such jurisdictions as the Underwriters designate and will continue such qualifications in effect so long as required for the distribution; provided that none of the Company or the Subsidiary Guarantors will be required to qualify as a foreign entity or to file a general consent to service of process in any such state.

(vii) The Company will pay all expenses incidental to the performance of its obligations under this Agreement and the Indentures, including (i) the fees and expenses of the Trustee and its professional advisers; (ii) all expenses in connection with the execution, issue, authentication, packaging and initial delivery of the Offered Securities and any other document relating to the issuance, offer, sale and delivery of the Offered Securities and the preparing, printing and distributing of any Issuer Free Writing Prospectuses to investors or prospective investors; (iii) the cost of any advertising approved by the Company in connection with the issue of the Offered Securities; (iv) any filing fees and other expenses (including fees and disbursements of counsel) incurred in connection with qualification of the Offered Securities for sale under the laws of such jurisdictions as the Representative designates and the printing of memoranda relating thereto; (v) any fees charged by investment rating agencies for the rating of the Offered Securities; and (vi) expenses incurred in distributing the preliminary prospectuses, preliminary prospectus supplements and the Prospectus (including any amendments and supplements thereto) to the Underwriters.

(viii) For a period of 60 days after the date of this Agreement, the Company will not offer, sell, contract to sell or otherwise distribute any notes, any security convertible into or exchangeable into or exercisable for notes or any other debt securities substantially similar to the Offered Securities (except for the Offered Securities issued pursuant to this Agreement), without the prior written consent of the Representative.

(ix) Before using, authorizing, approving or referring to any written communication that constitutes an offer to sell or a solicitation to buy the Offered Securities (other than the General Disclosure Package), the Company will furnish to the Underwriters and counsel for the Underwriters a copy of such written communication for review and will not use, authorize, approve or refer to any such written communication to which the Representative reasonably objects.

(x) The Company will apply the net proceeds of the offering and the sale of the Offered Securities in a manner consistent with the description contained in the General Disclosure Package under the caption “Use of Proceeds.”

6. Free Writing Prospectuses. The Company represents and agrees that (other than the final term sheet prepared and filed pursuant to Section 5(i) hereto), unless it obtains the prior consent of the Representative, and each Underwriter represents and agrees that (other than one or more term sheets relating to the Offered Securities containing customary information and conveyed to purchasers of Offered Securities), unless it obtains the prior consent of the Company and the Representative, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representative is hereinafter referred to as a “Permitted Free Writing Prospectus.” The

10

Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

7. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Offered Securities on the Closing Date will be subject to the accuracy of the representations and warranties on the part of the Company and each Subsidiary Guarantor herein, to the accuracy of the statements of officers of the Company and each Subsidiary Guarantor made pursuant to the provisions hereof, to the performance by the Company and each Subsidiary Guarantor of its obligations hereunder and to the following additional conditions precedent:

(i) The Underwriters shall have received a letter, dated on or prior to the date of this Agreement, of PricewaterhouseCoopers LLP, independent public accountants for the Company, in form and substance reasonably satisfactory to the Representative and PricewaterhouseCoopers LLP, which comfort letter shall address, without limitation, the various financial disclosures, if any, set forth in the Registration Statement and the General Disclosure Package.

(ii) The Prospectus shall have been filed with the Commission in accordance with the Act and Section 5(i) of this Agreement. No stop order suspending the effectiveness of the Registration Statement or of any part thereof or notice objecting to its use pursuant to Rule 401(g)(2) shall have been issued and no proceedings for that purpose shall have been instituted or, to the knowledge of the Company or any Underwriter, shall be contemplated by the Commission.

(iii) Subsequent to the execution and delivery of this Agreement, there shall not have occurred (i) any change, or any development or event involving a prospective change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries taken as one enterprise which, in the judgment of the Representative, is material and adverse and makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Offered Securities pursuant to this Agreement; (ii) any downgrading in the rating of any debt securities of the Company by any “nationally recognized statistical rating organization” (as defined for purposes of Section 3(a)(62) of the Exchange Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities of the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating) or any announcement that the Company has been placed on negative outlook; (iii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of the Representative, be likely to prejudice materially the success of the proposed issue, sale or distribution of the Offered Securities, whether in the primary market or in respect of dealings in the secondary market; (iv) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange, or any setting of minimum prices for trading on such exchange, or any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (v) any banking moratorium declared by U.S. Federal or New York authorities; (vi) any major disruption of settlements of securities or clearance services in the United States; or (vii) any attack on, outbreak or escalation of hostilities or acts of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of the Representative, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Offered Securities pursuant to this Agreement.

(iv) Baker Botts L.L.P., counsel to the Company, shall have furnished to the Representative, as of the Closing Date, its opinion, dated the Closing Date, substantially to the effect set forth in Exhibit A. In rendering such opinion, Baker Botts L.L.P. may rely (i) as to the incorporation of the Company and all other matters governed by Oklahoma law upon the opinion of Derrick & Briggs, L.L.P.

(v) On the Closing Date, the Representative shall have received, in form and substance reasonably satisfactory to them, the favorable opinion of Derrick & Briggs, L.L.P., counsel to the Company and certain of the Subsidiary Guarantors, dated the Closing Date, substantially to the effect set forth in Exhibit B.

11

In rendering such opinion, Cravath, Swaine & Moore LLP may rely as to the incorporation of the Company and all other matters governed by Oklahoma law upon the opinion of Derrick & Briggs, L.L.P. referred to above.

(vii) The Underwriters shall have received a certificate, dated the Closing Date, of the Chief Financial Officer, Treasurer or any Vice President of the Company in which such officers acting in such capacity (and not individually), shall state that the representations and warranties of the Company in this Agreement are true and correct as if made on and as of such date, that the Company has performed in all material respects all covenants and agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date, that no stop order suspending the effectiveness of the Registration Statement or of any part thereof or notice objecting to its use pursuant to Rule 401(g)(2) has been issued and no proceedings for that purpose have been instituted or are contemplated by the Commission and that, subsequent to the date as of which information is given in the General Disclosure Package (as amended or supplemented), as of the date of such certificate, there has not been any change in such information that would have a Material Adverse Effect, except as set forth in or contemplated by the Registration Statement and the General Disclosure Package or as described in such certificate.

(viii) The Underwriters shall have received a letter, dated such Closing Date, of PricewaterhouseCoopers LLP which meets the requirements of subsection (i) of this Section, except that the specified date referred to in such subsection will be a date not more than three business days prior to such Closing Date for the purposes of this subsection.

(ix) The Underwriters shall have received (i) a copy of the certificate or articles of incorporation, including all amendments thereto, of the Company, certified as of a recent date by the Secretary of State of the State of Oklahoma, (ii) a certificate of good standing for the Company, dated as of a recent date, from such Secretary of State and (iii) a certificate, dated as of a recent date, of the Secretary of State of each state in which the Company is qualified to do business as a foreign corporation under the laws of such state.

(x) The Underwriters shall have received (i) a copy of the certificate or articles of incorporation (or similar organizational document), including all amendments thereto, of the Subsidiary Guarantors, certified as of a recent date by the Secretary of State of the state in which such subsidiary is organized, (ii) a certificate of good standing for each such subsidiary of the Company, certified as of a recent date by the Secretary of State of the state in which such subsidiary is organized, and (iii) a certificate, dated as of a recent date, of the Secretary of State of each state in which each such subsidiary is qualified to do business as a foreign corporation (or similar entity) under the laws of each such state.

The Company will furnish the Underwriters with such conformed copies of such opinions, certificates, letters and documents as the Underwriters reasonably request. The Representative may in its sole discretion waive, on behalf of the Underwriters, compliance with any conditions to the obligations of any Underwriter hereunder.

8. Indemnification and Contribution. (i) Each of the Company and the Subsidiary Guarantors, jointly and severally, will indemnify and hold harmless each Underwriter, its affiliates and their respective partners, members, directors, officers, employees and agents and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the

12

Registration Statement, any Statutory Prospectus, the Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement thereto, any related preliminary prospectus or preliminary prospectus supplement, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or any Non-Prospectus Road Show, or arise out of or are based upon, with respect to the Registration Statement, the 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, with respect to the Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any amendment or supplement thereto, any related preliminary prospectus or preliminary prospectus supplement, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or any Non-Prospectus Road Show, the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company and the Subsidiary Guarantors will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by an Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by the Underwriters consists of the information described as such in Section 8(ii) below.

(ii) Each Underwriter will severally and not jointly indemnify and hold harmless the Company, its directors and officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act, against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Statutory Prospectus, the Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement thereto, any related preliminary prospectus or preliminary prospectus supplement, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or any Non-Prospectus Road Show, or arise out of or are based upon, with respect to the Registration Statement, the 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, with respect to any Statutory Prospectus, the Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement thereto, any related preliminary prospectus or preliminary prospectus supplement, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or any Non-Prospectus Road Show, the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by the Underwriters consists of the following information in the Prospectus: paragraphs 5, 6 and 7 under the caption “Underwriting”. The Company and the Underwriters acknowledge that no information has been furnished to the Company by an Underwriter for use in any Non-Prospectus Road Show.

(iii) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under Section 8(i) or 8(ii) above, notify the indemnifying party in writing of the commencement thereof; but the failure to notify the indemnifying party will not relieve it from any liability which it may have under Section 8(i) or 8(ii) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; provided that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party otherwise than under Section 8(i) or 8(ii) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the

13

indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, if such indemnified party shall have been advised by counsel that there are one or more defenses available to it that are in conflict with those available to the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party), the reasonable fees and expenses of such indemnified party’s counsel shall be borne by the indemnifying party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (together with appropriate local counsel) at any time for any indemnified party in connection with any one action or separate but substantially similar or related actions arising in the same jurisdiction out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(iv) If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under Section 8(i) or 8(ii) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in Section 8(i) or 8(ii) above (x) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other from the offering of the Offered Securities or (y) if the allocation provided by clause (x) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (x) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters from the Company under this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 8(iv) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this Section 8(iv). Notwithstanding the provisions of this Section 8(iv), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 8(iv) to contribute are several in proportion to their respective underwriting obligations and not joint.

(v) The obligations of the Company and the Subsidiary Guarantors under this Section 8 shall be in addition to any liability which the Company and the Subsidiary Guarantors may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls an Underwriter within the meaning of the Act or the Exchange Act; and the obligations of the Underwriters under this

14

Section 8 shall be in addition to any liability which the Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Act or the Exchange Act.

9. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on the Closing Date and the aggregate principal amount of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities, the non-defaulting Underwriters may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including the non-defaulting Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to the Representative and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 10. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section 9. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company and the Subsidiary Guarantors or their respective officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 9 or for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Company, the Subsidiary Guarantors and the Underwriters pursuant to Section 8 shall remain in effect, and if any Offered Securities have been purchased hereunder the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 or as a result of the failure of the condition in Section 7(iii) in connection with the occurrence of any event specified in clause (iii), (iv) (other than any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market), (v), (vi) or (vii) of Section 7(iii), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

11. Research Independence. In addition, the Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that the Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their investment bankers. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by the Underwriters’ independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by the Underwriters’ investment banking divisions. The Company acknowledges that the Underwriters are full service securities firms and as such from time to time, subject to applicable securities laws, may effect transactions for their own accounts or the accounts of their customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

15

12. No Fiduciary Duty. Each of the Company and the Subsidiary Guarantors acknowledges and agrees that in connection with this offering, the sale of the Offered Securities or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company, the Subsidiary Guarantors and any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, experts or otherwise, to the Company or the Subsidiary Guarantors, including, without limitation, with respect to the determination of the public offering price of the Offered Securities, and such relationship between the Company and the Subsidiary Guarantors, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arm’s-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company and the Subsidiary Guarantors shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company and the Subsidiary Guarantors. Each of the Company and the Subsidiary Guarantors hereby waives any claims that it may have against the Underwriters with respect to any breach of fiduciary duty in connection with the offering.

13. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed to the Representative, care of Goldman Sachs & Co. LLC, 200 West Street, New York, NY 10282, attention of Registration Department, with a copy to Cravath, Swaine & Moore LLP, 825 Eighth Avenue, New York, New York 10019 (fax: (212) 474-3700), Attention: Stephen Burns, Esq. or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at Chesapeake Energy Corporation, 6100 North Western Avenue, Oklahoma City, Oklahoma 73118, Attention: Corporate Secretary.

14. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 8, and no other person will have any right or obligation hereunder. The Representative will act for the several Underwriters in connection with this purchase and any action under this Agreement taken by the Representative will be binding upon all the Underwriters.

15. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

16. Applicable Law. This Agreement and any claim, controversy or dispute arising under or related to this Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without regard to principles of conflicts of laws. The Company and each Subsidiary Guarantor hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

17. Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

Each of the Underwriters, the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) and each Subsidiary Guarantor waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement.

16

If the foregoing is in accordance with the Underwriters’ understanding of our agreement, kindly sign and return to us one of the counterparts hereof, whereupon it will become a binding agreement among the Company, each Subsidiary Guarantor and the several Underwriters in accordance with its terms.

The foregoing Underwriting Agreement is hereby confirmed and accepted as of the date first above written.
