(e) The Joint Lead Dealer Managers shall have received such other documents and certificates as are reasonably requested by the Joint Lead Dealer Managers or their counsel.

7. Covenants. In further consideration of the Dealer Managers’ agreements herein contained, the Company covenants with the Dealer Managers as follows:

(b) Prior to amending or supplementing the Offering Documents (including any amendment or supplement through incorporation by reference of any report filed under the Exchange Act), the Company shall furnish to the Joint Lead Dealer Managers and their counsel for review at a reasonable time prior to filing a copy of each such proposed amendment or supplement, and the Company shall not use any such proposed amendment or supplement to which the Dealer Managers or their counsel reasonably object.

(c) The Company will advise the Joint Lead Dealer Managers promptly of (i) the occurrence of any event which could cause the Company to withdraw or terminate the Exchange Offer or would permit the Company to exercise any right not to exchange the New Notes for the tendered Old Notes, (ii) any proposal or requirement to make, amend or supplement the Offering Documents, (iii) the issuance of any order or the taking of any other action by any administrative or judicial tribunal or other governmental agency or instrumentality which would delay, prevent or adversely affect the Exchange Offer (and, if in writing, will furnish the Joint Lead Dealer Managers a copy thereof), (iv) any Material Adverse Change, or any development which could reasonably be expected to

have a Material Adverse Change, and (v) any other information relating to the Exchange Offer which the Dealer Managers may from time to time reasonably request.

8. Indemnification. The Company agrees to indemnify and hold harmless each Dealer Manager and such Dealer Manager’s affiliates and officers, directors, employees, agents and each person, if any, who controls any Dealer Manager within the meaning of the Securities Act and the Exchange Act (each a “Dealer Manager Indemnified Person”) from and against any and all losses, claims, damages, liabilities and expenses, joint or several, to which any such Dealer Manager Indemnified Person may become subject arising out of or based upon (A) any untrue statement or alleged untrue statement of a material fact contained in the Offering Documents or any of the documents incorporated by reference therein or in any amendment or supplement to any of the foregoing, or 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, (B) any breach by the Company of any representation or warranty or failure to comply with any of the agreements of the Company set forth in the Agreement, (C) any withdrawal, termination, rescission or modification of, or failure to make or consummate, the Exchange Offer or to exchange any of the New Notes for the Old Notes or (D) the transactions contemplated by the Agreement, or the performance by each Dealer Manager thereunder, or any claim, litigation, investigation or proceedings relating to the foregoing (“Dealer Manager Proceedings”) regardless of whether any of such Dealer Manager Indemnified Persons is a party thereto, and to reimburse such Dealer Manager Indemnified Persons for any reasonable legal or other reasonable out-of-pocket expenses in connection with investigating or

defending, settling, compromising or paying for any of the foregoing; provided that the foregoing indemnification will not, as to any Dealer Manager Indemnified Person, apply to losses, claims, damages, liabilities or expenses to the extent, but only to the extent, that they have resulted from (i) the gross negligence or willful misconduct of such Dealer Manager Indemnified Person or (ii) in the case of the indemnity provided in clause (A) above of this paragraph, an untrue statement of a material fact or omission to state a material fact made in reliance upon and in conformity with the information furnished in writing by the Dealer Managers expressly for inclusion in the Offering Documents. This indemnity agreement shall be in addition to any liability which the Company may otherwise have.

The Company shall not be liable for any settlement of any lawsuit, claim or proceeding effected without its written consent (which consent shall not be unreasonably withheld or delayed), but if settled with such consent, the Company agrees, subject to the provisions of this Section 8, to indemnify the Dealer Manager Indemnified Person from and against any loss, damage or liability by reason of such settlement.

Each Dealer Manager agrees, severally and not jointly, to indemnify and hold harmless each of the Company and its affiliates and officers, directors, employees, agents and each person, if any, who controls the Company within the meaning of the Securities Act and the Exchange Act (each a “Company Indemnified Person”) from and against any and all losses, claims, damages, liabilities and reasonable expenses, joint or several, to which any such Company Indemnified Person may become subject arising out of or based upon the transactions contemplated by the Agreement or the performance by the Dealer Managers thereunder, or any claim, litigation, investigation or proceedings relating to the foregoing (“Company Proceedings”) regardless of whether any of such Company Indemnified Persons is a party thereto, and to reimburse such Company Indemnified Persons for any reasonable legal or other reasonable out-of-pocket expenses as they are incurred in connection with investigating or defending any of the foregoing, but only to the extent such losses, claims, damages, liabilities or expenses have resulted from (i) the gross negligence or willful misconduct of such Dealer Manager or (ii) an untrue statement of a material fact or omission to state a material fact made in reliance upon and in conformity with the information furnished in writing by such Dealer Manager expressly for inclusion in the Offering Documents. The Company acknowledges that the information furnished by the Dealer Managers (as described in clause (ii) of the preceding sentence) refers solely to the identity, address and phone number of each Dealer Manager appearing on the front cover page and the back cover page of the prospectus that forms a part of the Registration Statement. The terms “Dealer Manager Indemnified Person” and “Company Indemnified Person” are herein collectively referred to as an “Indemnified Person” and the terms “Dealer Manager Proceedings” and “Company Proceedings” are herein collectively referred to as “Proceedings.”

The Dealer Managers shall not be liable for any settlement of any lawsuit, claim or proceeding effected without their written consent (which consent shall not be unreasonably withheld or delayed), but if settled with such consent, each Dealer Manager agrees, severally and not jointly, subject to the provisions of this Section 8, to indemnify the Company Indemnified Person from and against any loss, damage or liability by reason of such settlement.

Promptly after receipt by an Indemnified Person of notice of the commencement of any Proceedings, such Indemnified Person will, if a claim in respect thereof is to be made against the Company or the Dealer Managers, as the case may be, as indemnifying party (the “Indemnifying Party”) for indemnification hereunder, promptly notify such Indemnifying Party in writing of the commencement thereof; provided that (i) the omission so to notify the Indemnifying Party will not relieve any Indemnifying Party from any liability which it may have hereunder except to the extent it has been materially prejudiced by such failure and (ii) the omission so to notify such Indemnifying Party will not relieve it from any liability which it may have to such Indemnified Person independently of this Section 8. In case any such Proceedings are brought against any Indemnified Person and it notifies the applicable Indemnifying Party of the commencement thereof, such Indemnifying Party will be entitled to participate therein, and, to the extent that it may elect by written notice delivered to such Indemnified Person, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Person; provided that if the defendants in any such Proceeding include both such Indemnified Person and the Indemnifying Party and counsel to such Indemnified Person shall have reasonably concluded that there may be legal defenses available to it which are different from or additional to those available to the Indemnifying Party, such Indemnified Person shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such Proceedings on behalf of such Indemnified Person. Upon receipt of notice from the Indemnifying Party to such Indemnified Person of its election so to assume the defense of such Proceedings and approval by such Indemnified Person of counsel, the Indemnifying Party shall not be liable to such Indemnified Person for expenses incurred by such Indemnified Person in connection with the defense thereof (other than reasonable costs of investigation) unless (i) such Indemnified Person shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the Indemnifying Party shall not be liable for the expenses of more than one separate counsel, representing all the Indemnified Persons who are parties to such Proceedings, such counsel to be designated in writing by a majority of the Indemnified Persons who are parties to such Proceedings), (ii) the Indemnifying Party shall not have employed counsel reasonably satisfactory to such Indemnified Person to represent such Indemnified Person within a reasonable time after notice of commencement of the Proceedings or (iii) the Indemnifying Party shall have authorized in writing the employment of counsel for such Indemnified Person; and except that, if clause (i) or (iii) is applicable, such liability shall be only in respect of the counsel referred to in such clause (i) or (iii). The Indemnifying Party shall not effect, without the prior written consent of the Indemnified Person (which consent shall not be unreasonably withheld or delayed), any settlement of any pending or threatened proceeding unless such settlement includes an unconditional release from the party bringing such proceeding of such Indemnified Person and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

If for any reason the foregoing indemnification is unavailable to any Indemnified Person or insufficient to hold it harmless, then each applicable Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Person as a result of such loss, claim, damage, liability or expense in such proportion as is appropriate to reflect not only the relative benefits received by the Indemnifying Party on the one hand and such Indemnified Person on the other hand, but also the relative fault of Indemnifying Party on the one hand, and such Indemnified Person, on the other hand, as well as any relevant equitable considerations. It is hereby agreed

that the relevant benefits to the Company (including its affiliates, officers, directors, employees, agents and controlling persons) on one hand and the Dealer Managers (including their affiliates, officers, directors, employees, agents and controlling persons) on the other hand shall be deemed to be in the same proportion as (i) the aggregate principal amount of the New Notes issued pursuant to the Exchange Offer bears to (ii) the aggregate Fees paid or proposed to be paid to the Dealer Managers pursuant to Section 3(a). The relative faults of the Company (including its affiliates, officers, directors, employees, agents and controlling persons) on the one hand and each Dealer Manager (including its affiliates, officers, directors, employees, agents and controlling persons) on the other hand relating to an untrue or alleged untrue statement of material fact or the omission or alleged omission to state a material fact shall be determined by reference to, among other things, the extent to which the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact is based upon information supplied by or on behalf of the Company and each Dealer Manager and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The provisions set forth in the immediately preceding paragraph with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under the immediately preceding paragraph for purposes of indemnification.

The Company and the Dealer Managers agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Dealer Managers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8.

The indemnity, reimbursement and contribution obligations of an Indemnifying Party under this Section 8 shall be in addition to any liability which such Indemnifying Party may otherwise have to an Indemnified Party, and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of such Indemnifying Party and any such Indemnified Person. Notwithstanding the foregoing, in no event shall any Dealer Manager be liable under this Section 8 in an amount in excess of the Fee actually received by such Dealer Manager pursuant to Section 3(a). 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 Dealer Managers’ obligations to contribute pursuant to this Section 8 are several and not joint in proportion to their respective share of the aggregate Fee paid by the Company pursuant to Section 3(a).

9. Confidentiality. Each Dealer Manager shall use all information provided to it by or on behalf of the Company hereunder solely for the purpose of providing the services which are the subject of this Agreement and the transactions contemplated hereby and shall treat confidentially all such information; provided that nothing herein shall prevent any Dealer Manager from disclosing any such information (i) pursuant to the order of any court or administrative or similar proceeding, (ii) upon the request of any governmental agency or regulatory authority having jurisdiction over such Dealer Manager or any of its affiliates, (iii) to the extent that such information becomes publicly available other than by reason of disclosure by such Dealer Manager, (iv) to its employees, legal counsel, independent auditors and other experts or agents who need to know such information and are informed of the confidential nature of such information, (v) to any of its affiliates who have been notified in advance of the confidential

nature of such information and (vi) in the Offering Documents. Each Dealer Manager shall be responsible for compliance by its disclosee with this Section 9. With respect to clause (i) above, prior to making any such disclosure, each Dealer Manager shall promptly notify the Company of such order or request and use commercially reasonable efforts to cooperate with the Company, at the Company’s expense, in seeking a protective order or taking such action as the Company may reasonably request consistent with applicable law.

10. Survival. The agreements contained in Sections 3, 8 and 9 hereof and the representations and warranties of the Company set forth in Section 5 hereof shall remain operative and in full force and effect, regardless of (i) any failure to commence, or the withdrawal, termination or consummation of, the Exchange Offer or the termination or assignment of this Agreement, (ii) any investigation made by or on behalf of the Company or any Indemnified Person and (iii) any withdrawal by the Dealer Managers pursuant to Section 2 hereof.

11. No Liability for Acts of Dealers, Banks and Trust Companies. The Dealer Managers shall have no liability to the Company or any other person for any losses, claims, damages, liabilities and expenses (each a “Loss” and collectively, the “Losses”) arising from any act or omission on the part of any broker or dealer in securities (a “Dealer”) or any bank or trust company, or any other person, and neither any Dealer Manager nor any of its affiliates shall be liable for any Losses arising from its own acts or omissions in performing its obligations as Dealer Manager or as a Dealer hereunder or otherwise in connection with the Exchange Offer, except for any such Losses (i) arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information furnished in writing by the Dealer Manager expressly for inclusion in the Offering Documents, or (ii) which are finally judicially determined to have resulted from such Dealer Manager’s gross negligence or willful misconduct (it being understood that any such liability of any Dealer Manager shall be several and not joint). In soliciting or obtaining tenders of Old Notes, no Dealer, bank or trust company shall be deemed to be acting as the agent of the Company or any of its affiliates, and no Dealer Manager shall be deemed the agent of any Dealer, bank or trust company or the agent or fiduciary of the Company or any of its affiliates, equity holders, creditors or of any other person. In soliciting or obtaining tenders of Old Notes, the Dealer Managers shall not be nor shall the Dealer Managers be deemed for any purpose to act as partners or joint venturers of or members of a syndicate or group with the Company or any of its affiliates in connection with the Exchange Offer or otherwise, and neither the Company nor any of its affiliates shall be deemed to act as the Dealer Managers’ respective agents. The Company shall have sole authority for the acceptance or rejection of any and all tenders of Old Notes.

12. Governing Law; Jurisdiction; Judgment Currency. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts to be performed wholly within the State of New York. The parties hereto consent to the non-exclusive jurisdiction of the courts of the State of New York and the federal courts located in the Borough of Manhattan, City of New York in any action or proceeding related to this Agreement (except that a judgment obtained in such courts may be enforced in any jurisdiction). All judgments arising from such litigation or settlements related thereto shall be paid in United States Dollars.

13. Notices. Except as otherwise expressly provided in this Agreement, whenever notice is required by the provisions of this Agreement to be given to (i) the Company such notice shall be in writing addressed to Chesapeake Energy Corporation, 6100 North Western Avenue, Oklahoma City, Oklahoma 73118, Attention: Marcus C. Rowland, Executive Vice President and Chief Financial Officer; and (ii) the Dealer Managers or to the Joint Lead Dealer Managers, such notice shall be in writing addressed to (A) Banc of America Securities LLC, Bank of America Corporate Center, 100 North Tryon Street, Twelfth Floor, Charlotte, North Carolina 28255, facsimile number: (704) 388-0830, Attention: Andrew C.

14. Conditions to the Exchange Offer. Nothing in this Agreement shall obligate the Company to proceed with or consummate the Exchange Offer, and the Company may terminate the Exchange Offer, unless each of the conditions set forth under “The Exchange Offer—Conditions to the Exchange Offer” in the Prospectus is satisfied (as determined by the Company in its sole discretion) or is otherwise waived by the Company, in each case, on or prior to the date on which the Exchange Offer expires (taking into account any extensions thereof).

15. 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. This Agreement may not be amended or modified except by a writing executed by each of the parties hereto. Section headings herein are for convenience only and are not a part of this Agreement.

(a) This Agreement is solely for the benefit of the Company and the Dealer Managers, and no other person (except for Indemnified Persons, to the extent set forth in Section 8 hereof) shall acquire or have any rights under or by virtue of this Agreement.

(b) Each Dealer Manager may (subject to Section 9 hereof) share any information or matters relating to the Company or the Exchange Offer, and the transactions contemplated hereby with its affiliates, and such affiliates may likewise share information relating to the Company with such Dealer Manager; provided, however, that each Dealer Manager will not, and will ensure its employees and affiliates do not, share any such information with any of its or its affiliates’ employees on the public side of such Dealer Manager’s information wall. Each Dealer Manager shall be responsible for compliance by its affiliates with Section 9 hereof.

(c) 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 and the Dealer Managers 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.

(d) This Agreement may be executed in counterparts, each of which will be deemed an original, but all of which, taken together, will constitute one and the same instrument.

Please indicate your willingness to act as Dealer Managers on the terms set forth herein and your acceptance of the foregoing provisions by signing in the space provided below for that purpose and returning to us a copy of this letter, whereupon this letter shall constitute a binding agreement between us.
