SUBORDINATED UNSECURED NOTE

For value received, ENERGY & EXPLORATION PARTNERS, INC., a Delaware corporation (the “Company”), hereby promises to pay to the order of CHESAPEAKE EXPLORATION, L.L.C., an Oklahoma limited liability company (together with any subsequent holder or assigns of this Note, the “Payee”) the principal amount of Eighteen Million and No/100 Dollars ($18,000,000.00), on the Chesapeake Maturity Date, subject to earlier prepayment as provided herein, together with interest thereon calculated on the unpaid principal amount of this Note outstanding from time to time, from and including the date hereof, and paid in accordance with the provisions of this Note. The term “Chesapeake Maturity Date” means the earlier of (i) October 8, 2018 or (ii) the date of a Liquidity Event or (iii) six (6) months after the date of Senior Payment in Full.

Section 1. Interest and Seniority.

1.1 Payment of Interest. Interest on this Note shall accrue at the Applicable Rate (as hereinafter defined) or, if less, the highest rate permitted by applicable law, compounded semi-annually and computed on the basis of a 365-day year for the actual number of days elapsed in such period, and shall be paid by the Company in arrears on the last Business Day of each June and December during the term hereof and on the Chesapeake Maturity Date (each, a “Payment Date”). The “Applicable Rate” means ten percent (10%) per annum at any time prior to the date Senior Payment in Full has occurred and fifteen percent (15%) per annum at any time thereafter. Until the Senior Payment in Full has occurred, interest on this Note for any period shall only be paid by the Company in kind (“PIK”),with any such PIK interest being added to the principal balance of this Note. If the Senior Payment in Full has occurred, subject to Section 3, the

Company shall have the option to pay interest on this Note for the period ending on such Payment Date either in cash or in kind, it being agreed that failure to make cash interest payments when due will automatically convert such interest to PIK interest. Interest will accrue from time to time on any principal balance of this Note (including principal additions from payments of PIK interest) then outstanding. Any accrued interest on this Note that for any reason has not theretofore been paid or converted to principal will be due and payable in full on the Chesapeake Maturity Date.

1.2 Seniority. This Note (i) shall be senior with respect to any and all distributions, dividends, and redemptions (including but not limited to any distribution or dividend in connection with dissolution or liquidation) with respect to all equity interests of the Company, and (ii) shall rank junior and subordinate to all Senior Debt to the extent and in the manner set forth herein.

1.3 Other Creditors. Nothing contained in this Note is intended to or shall impair, as between the Company, its creditors other than the holders of Senior Debt (and the Persons and entities committed or obligated to issue or fund any Senior Debt), and the holder of this Note, the obligation of the Company, which is absolute and unconditional, to pay to the holder hereof the principal hereof and interest hereon, as and when the same shall become due and payable in accordance with the terms hereof, or is intended to or shall affect the relative rights of the holder hereof and other creditors of the Company other than the holders of the Senior Debt (and the Persons and entities committed or obligated to issue or fund any Senior Debt), nor, subject to Section 3, shall anything in this Note prevent the holder from exercising all remedies otherwise permitted by applicable law upon the happening of any Event of Default under this Note.

1.4 Reinstatement. The Company is and shall be obligated to pay all principal and interest and any and all amounts which become payable under this Note in accordance with the terms hereof absolutely and unconditionally and without abatement, postponement, diminution or deduction whatsoever and without any reduction or counterclaim or setoff whatsoever. If at any time payment received by Payee hereunder shall be deemed by a court of competent jurisdiction to have been a voidable preference or fraudulent conveyance under the Bankruptcy Code, then the obligation to make such payment shall survive any cancellation or satisfaction of this Note or return thereof to the Company and shall not be discharged or satisfied with any prior payment thereof or cancellation of this Note, but shall remain a valid and binding obligation enforceable in accordance with the terms and provisions hereof, and such payment shall be immediately due and payable upon demand.

1.5 Payment. Notwithstanding anything to the contrary in this Note, the Company shall pay this Note in full by paying to the Payee the entire unpaid principal balance of this Note plus all accrued and unpaid interest thereon within three (3) Business Days after the Chesapeake Maturity Date.

Section 2. Optional Prepayment by the Company. Subject to Section 3 below, and provided that either the Senior Payment in Full has occurred or the Company has obtained the prior written consent of the required Senior Creditors under each Credit Facility then outstanding, this Note may be prepaid, in cash, at the option of the Company, in whole or in part at any time after the Effective Date and on a Prepayment Date by giving the notices and making

2

the payment of the amount required hereby. The Company will send written notice of its election to prepay this Note to the Payee by registered or certified mail, return receipt requested, or shall deliver notice of such election by hand delivery or by express delivery or other delivery service at least five (5) days prior to the date of prepayment (which date of prepayment must be at least one day prior to the Chesapeake Maturity Date) (the “Prepayment Date”). On the Prepayment Date, the Company will deliver to the Payee upon surrender of this Note: (a) an amount equal to (a)(i) the principal amount of the Note being prepaid (which amount shall not be less than the lesser of $1,000,000 or the remaining principal balance of the Note) plus (ii) accrued, unpaid interest on the principal amount being prepaid to the date of prepayment (the “Prepayment Amount”). If less than the entire remaining principal amount of this Note is to be prepaid, in addition to delivering the Prepayment Amount, on the Prepayment Date, the Company shall also deliver to and in the name of the appropriate Person, a new Note payable to the Payee, dated the later of the date of this Note or the last Prepayment Date, in a principal amount equal to the unpaid portion of this Note and having other terms identical to this Note. On and after any Prepayment Date, unless the Company defaults in the payment of the Prepayment Amount, interest shall cease to accrue on the portion of this Note subject to prepayment.

Section 3. Subordination.

3.1 The Payee hereby subordinates any and all claims now or hereafter owing to it by the Company under this Note to any and all Senior Debt (including, without limitation, interest, fees, costs, reimbursements or other payments on the Senior Debt paid or accrued after the commencement of an Insolvency Proceeding (as hereinafter defined) and whether or not such claims are allowed or deemed allowed or recoverable in any Insolvency Proceeding, and payment of or for adequate protection pursuant to any Insolvency Proceeding), and agrees that, except as set forth in Section 3.2 below, Senior Payment in Full shall have occurred before any payment may be made on this Note, whether of principal or interest or other indebtedness or other obligations. Except with respect to the exercise of remedies by the Payee in accordance with Section 3.4 hereof, the Payee agrees not to acquire any security interests in, security titles to, and other liens and encumbrances on any assets, properties or rights of the Company, or its direct or indirect subsidiaries (the “Credit Parties”). In the event that the Payee should acquire any security titles to, and other liens and encumbrances on any of the present or future collateral securing or purporting to secure the Senior Debt (the “Senior Collateral”), the Payee hereby subordinates and makes inferior any and all of its now existing or hereafter acquired security interests in such security titles to, and other liens and encumbrances on any of the present or future Senior Collateral, any security interests, security titles or other liens and encumbrances on the Senior Collateral arising under any security agreement created or existing in respect of the Senior Debt, regardless of whether any Senior Creditor has taken or failed to take any action with respect to the creation, perfection or continuation of liens, security interests or encumbrances in the Senior Debt, including, but not limited to, the failure to file any necessary financing statements, mortgages, deeds of trust or other security documents or the rejection of the filing of any of the foregoing. In case any funds shall be paid or delivered to the Payee in violation of this paragraph, such funds shall be held in trust by the Payee for and immediately paid and delivered to the Senior Creditors (in the form received endorsed over to the Senior Creditors) for application to the payment of Senior Debt.

3

3.2 Notwithstanding anything to the contrary contained herein, (i) the Company may make payments of PIK interest, and (ii) the Company may repay the Note if a Liquidity Event occurs, together with all accrued and unpaid interest.

3.3 The Payee agrees that the priority of the Senior Debt set forth above shall continue during any insolvency, receivership, bankruptcy, dissolution, liquidation, or reorganization proceeding, or in any other proceeding, whether voluntary or involuntary, by or against the Company, under any bankruptcy or insolvency law or other similar laws, including, without limitation, any federal or state law relating to the relief of debtors of any jurisdiction, or involving any custodian, liquidator or trustee whether now or hereafter in effect, and in any out-of-court composition, assignment for the benefit of creditors, readjustment of indebtedness, reorganization, extension or other debt arrangement of any kind (collectively, an “Insolvency Proceeding”). In the event of any payment, distribution, division or application, partial or complete, voluntary or involuntary, by operation of law or otherwise, of all or any part of the property, assets or business of the Company or any subsidiary, or the proceeds thereof, or any securities of the Company, to the Payee, by reason of any liquidation, dissolution or other winding up of the Company or its business or by reason of any sale or Insolvency Proceeding, then any such payment or distribution of any kind or character, whether in cash, property or securities, which, but for the subordination provisions of this Section 3, would otherwise be payable or deliverable upon or in respect of this Note, shall instead be paid over or delivered directly to the Senior Creditors, for application to the payment of the Senior Debt, to the extent necessary to make payment of the Senior Debt remaining unpaid after giving effect to any concurrent payment or distribution to the Payee, and no holder of this Note shall receive any such payment or distribution or any benefit therefrom until the occurrence of the Senior Payment in Full after which such payments or distributions may be applied to payment of the indebtedness evidenced by this Note if and to the extent permitted by law.

3.4 Until the Chesapeake Maturity Date, the Payee shall not (a) take any action or exercise any remedy against the Company to enforce the obligations of the Company under this Note; (b) take any action or exercise any remedy against any Credit Party or any other guarantor of, or pledgor securing, the Senior Debt in order to collect any of the indebtedness evidenced by this Note; or (c) commence, or join with any other creditor of the Company in commencing, any bankruptcy, reorganization or Insolvency Proceeding against any Credit Party; or (d) take any action or exercise any remedy related to this Note against any property or assets of any Credit Party or any other guarantor of, or pledgor securing, the Senior Debt; provided that, if any Insolvency Proceedings shall be initiated by, or filed against, the Company, then the Payee shall be permitted to accelerate the obligations owing under this Note (but shall not be permitted to take any other action or exercise any other remedy against any Credit Party without the prior written consent of the Senior Creditors). Any amounts collected by the Payee shall be subject to Sections 3.1, 3.2, and 3.3. Notwithstanding anything contained in this Note to the contrary, in no event shall the Payee be entitled to receive and retain any securities, equity or otherwise, or other consideration in respect of the indebtedness evidenced by this Note provided for in (x) a plan of reorganization or otherwise in connection with any bankruptcy or Insolvency Proceeding or (y) any other judicial or nonjudicial proceeding for the liquidation, dissolution or winding up of the Company or any other Credit Party or the assets or properties of the Company, in any case unless either (i) the Senior Payment in Full has occurred or (ii) the consideration received is effectively subordinate to the Senior Debt on terms no less beneficial to the holders of Senior Debt as the terms provided in this Note.

4

3.5 The Payee agrees, solely for the benefit of the holders of Senior Debt, that no consent of the Payee or any other holder of this Note shall be required for any modification, renewal, extension, rearrangement, increase or refinancing of any Senior Debt, or waiver of any guaranty therefor, or release of any Senior Collateral, or any other alteration of the relationship between any Credit Party and any holder of Senior Debt.

3.6 Until the Senior Payment in Full has occurred, the Payee waives all rights of subrogation, reimbursement and any similar rights with respect to the indebtedness evidenced by this Note. Until the Senior Payment in Full has occurred, to the extent permitted by law, the Payee shall be subrogated to the rights of the Senior Creditors to receive any distribution of assets of the Company, or payments by or on behalf of the Company, made on the Senior Debt, until the Senior Payment in Full has occurred. No payments to the Payee pursuant to any right of subrogation shall, as among the Company, its creditors other than the Senior Creditors and the Payee, be deemed to be a payment or distribution by the Company on account of the Senior Debt.

3.7 The Payee acknowledges and agrees that each Senior Creditor, whether the Senior Debt held by such Senior Creditor is outstanding at the date of this Note or incurred hereafter, shall have extended credit to the Company, or shall have purchased or accepted or will purchase or accept such Senior Debt, in reliance upon the subordination and standstill provisions contained in this Note.

3.8 In the event (A) the Senior Payment in Full has not occurred, and (B) the Payee and other holders of the indebtedness evidenced by this Note shall have not promptly filed a claim or proof or claim in respect of the indebtedness evidenced by this Note in connection with an Insolvency Proceeding, the Senior Creditors and the Agents, as applicable, shall each have the right to act as attorney-in-fact for the Payee and other holders of the indebtedness evidenced by this Note for the purposes of filing a claim or proof of debt in respect of the indebtedness evidenced by this Note in the form required in any such Insolvency Proceeding for and on behalf of the holders of indebtedness evidenced by this Note.

3.9 All of the Senior Debt (or any commitments in respect of such Senior Debt) shall be deemed to have been made or incurred in reliance upon this Note. The Payee expressly waives all notice of the acceptance by any Senior Creditor of the subordination and other provisions of this Note and all other notices not specifically required pursuant to the terms of this Note whatsoever, and the Payee expressly consents to reliance by the Senior Creditors upon the subordination and other agreements as herein provided. The Payee agrees that the Senior Creditors have not made warranties or representations with respect to the due execution, legality, validity, completeness or enforceability of any Senior Documents, the collectibility of the obligations thereunder; that the Senior Creditors shall be entitled to manage and supervise their loans or other extensions of credit in accordance with applicable law and their usual practices, modified from time to time as they deem appropriate under the circumstances; and that the Senior Creditors shall not have any liability to the Payee for, and the Payee waives any claim (except with respect to gross negligence or willful misconduct) which the Payee may now or

5

hereafter have against any Senior Creditor arising out of or relating to (i) any and all actions which such Senior Creditor takes or omits to take (including, without limitation, actions with respect to the creation, perfection or continuation of liens or security interests in the Senior Debt, actions with respect to the occurrence of a “Default” or “Event of Default” under any Credit Facility, actions with respect to the foreclosure upon, sale, release, or depreciation of, or failure to realize upon, any Senior Collateral and actions with respect to the collection of any claim for all or any part of the Senior Debt from any account debtor, guarantor or any other party) with respect to the documents regarding the Senior Debt or any other agreement related thereto or to the collection of the Senior Debt or the valuation, use, protection or release of the Collateral and/or other security for the Senior Debt, (ii) such Senior Creditor’s election, in any proceeding instituted under Chapter 11 of Title 11 of the United States Code (11 U.S.C. § 101 et seq.) (the “Bankruptcy Code”), of the application of Section 1111(b)(2) of the Bankruptcy Code or any other Insolvency Proceeding, and/or (iii) any making of loans to, or grant of a security interest under Section 364 of the Bankruptcy Code by, the Company as debtor or debtor-in-possession.

3.10 The Payee hereby agrees that the Senior Creditors shall have absolute power and discretion, without notice to the Payee in its capacity as a creditor under this Note, to deal in any manner with the Senior Debt, including demanding payment of interest, costs and expenses payable by any Credit Party to the Senior Creditors, and any security and guaranties therefor including, but not limited to, release, surrender, extension, renewal, acceleration, compromise, or substitution. The Payee hereby waives and agrees not to assert against any Senior Creditor any rights that a guarantor or surety could exercise, including without limitation any and all rights to notice of the creation, renewal, extension, modification, compromise or release of any of the Senior Debt or any collateral therefor or guaranties thereof, in whole or in part; but nothing in this Note shall constitute the Payee a guarantor or surety. If, at any time hereafter, the Senior Creditors shall, in their own judgment, determine to discontinue the extension of credit to or on behalf of the Company in compliance with the Senior Documents, the Senior Creditors may do so. The Payee acknowledges that, in accepting the subordinated claim provided for herein, it did not and is not relying in any way upon the extensions of credit by the Senior Creditors to the Company. The obligations of the Payee owing to the Senior Creditors hereunder, and the Senior Creditors’ rights and privileges hereunder shall continue until the Senior Payment in Full has occurred, notwithstanding any action or non-action by the Senior Creditors with respect to the Senior Debt or with respect to any Collateral therefor or any guaranties thereof. All rights, powers and remedies hereunder shall apply to all past, present and future Senior Debt and commitments with respect thereto, including under successive transactions, any of which may continue, renew, increase, decrease or from time to time create new Senior Debt and notwithstanding that from time to time the Senior Debt theretofore existing may have been paid in full. Any provision of any document, instrument or agreement evidencing, securing or otherwise relating to the indebtedness evidenced by this Note purporting to limit or restrict in any way the Company’s ability to enter into any agreement with any Senior Creditor to amend or modify any document, instrument or agreement evidencing, securing or otherwise relating to the Senior Debt shall be deemed of no force or effect until the Senior Payment in Full has occurred.

3.11 The obligations hereunder of the Payee or any other holders of indebtedness evidenced by this Note shall continue to be effective, or be reinstated, as the case may be, if at any time any payment in respect of any Senior Debt is rescinded or must otherwise be restored or returned by a holder of Senior Debt by reason of any Insolvency Proceeding or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Company or any substantial part of its property, or otherwise, all as though such payment had not been made.

6

3.12 The Payee agrees to pay all costs, legal expenses and attorneys’, paralegals’ and other professionals’ fees of every kind paid or incurred by the Agents and the Senior Creditors in enforcing their rights hereunder against the Payee, including, but not limited to, litigation instituted in a state or federal court, as hereinafter provided (including, without limitation, proceedings under the Bankruptcy Code or any Insolvency Proceeding) to enforce this Note, promptly on demand of the Senior Creditors or other Person paying or incurring the same.

3.13 The Company agrees to pay all costs, legal expenses and attorneys’, paralegals’ and other professionals’ fees of every kind paid or incurred by the Payee in enforcing its rights hereunder (including, without limitation, enforcement against any Credit Party), including, but not limited to, litigation instituted in a State or Federal Court, as hereinafter provided (including, without limitation, proceedings under the Bankruptcy Code or any Insolvency Proceeding) in enforcing this Note, promptly on demand of the Payee or other Person paying or incurring the same.
