(iii) subject to the provisions of Section 7.8, all rights and claims arising, occurring, or existing in favor of SEP prior to the Effective Time, including, but not limited to, any and all contract rights, claims, penalties, receivables, revenues, recoupment rights, recovery rights, accounting adjustments, mispayments, erroneous payments, personal or corporate injury, property damages, royalty and other rights and claims of any nature in favor of Sanchez relating to any time period prior to the Effective Time;

(iv) all of SEP’s insurance contracts and rights, titles, claims and interests of SEP related to the conveyed assets for all periods prior to the Effective Time (A) under any policy or agreement of insurance or indemnity, (B) under any bond or letter of credit or other security device, or (C) to any insurance or condemnation proceeds or awards, together with all amounts due or payable to Sanchez as adjustments to insurance premiums related to the conveyed assets for all periods prior to the Effective Time;

(v) claims of SEP for any refund of or loss carryforwards with respect to (A) production, windfall profit, severance, ad valorem or any other taxes attributable to the conveyed assets for any period prior to the Effective Time and (B) income, occupational or franchise taxes;

(vi) all monies, proceeds, benefits, receipts, credits, income or revenues (and any security or other deposits made) attributable to the Company Assets or the ownership or operation thereof prior to the Effective Time, including, without limitation, amounts recoverable from audits under operating agreements and any overpayments of royalties to the extent attributable to the period prior to the Effective Time;

(vii) any oil and gas leases other than those described in Section 1.2(a)(i);

(viii) any oil and gas wells other than those described in Section 1.2(a)(ii); and

(ix) any other assets identified on Schedule 1.2(b).

(c) Notwithstanding the foregoing, it is agreed and understood that the Company Assets which were conveyed to the Company by SEP only include the right, title and interest held by SEP in such assets and only to the extent such Company Assets are transferable. To the extent that any third-party consents or approvals were or are required in conjunction with the transfer of the Company Assets to the Company or the subsequent transfer of the Assigned Equity to CEP and such consents or approvals have not been obtained as of the Closing Date (the “Required Consents”), including, without limitation, those set forth on Schedule 1.2(c), Sanchez will use its commercially reasonable efforts to obtain, or cause SEP to obtain, the Required Consents as promptly as commercially practicable and will be responsible for all costs in connection therewith. The Parties agree that the Company Assets for which Required Consents must be obtained shall not be conveyed by SEP to the Company prior to the Closing but shall continue to be held by SEP for the benefit of the Company pending the receipt of the applicable

Required Consent (such Company Assets until such time conveyed to the Company, the “Non-Conveyed Assets”) but in any event for not longer than a period of one year from the Closing (the “Holding Period”) unless otherwise agreed by the Parties. At such time as a Required Consent is obtained, Sanchez shall cause SEP to promptly assign the Non-Conveyed Assets associated with such Required Consent to the Company. In consideration for the foregoing, during such time that SEP holds Non-Conveyed Assets, CEP shall directly pay (to SEP or as otherwise directed by Sanchez) within 10 days of a written request, all obligations relating to such Non-Conveyed Assets and all of the costs of administering such Non-Conveyed Assets from and after the Effective Time. If at the end of the Holding Period, SEP continues to hold any Non-Conveyed Assets, such Non-Conveyed Asset shall be deemed an Excluded Asset. Notwithstanding anything in this Agreement or otherwise to the contrary, nothing herein shall constitute an agreement to assign any claim, right or benefit arising under or resulting from a Company Asset if an attempted assignment thereof, without the consent of a third party, would constitute a breach or other contravention of the rights of such third party, would be ineffective with respect to any party to an agreement concerning such Company Asset, or would in any way adversely affect the rights of SEP, or upon transfer, the Company, to such Company Asset and in such event such Company Asset shall be deemed to have been an Excluded Asset and held for the benefit of the Company by SEP (and SEP will be entitled to payment from CEP for all obligations relating to such assets) in accordance with the foregoing provisions. If at the end of the Holding Period, SEP continues to hold any Non-Conveyed Assets, Sanchez shall, or shall cause SEP to, within 10 Business Days thereafter, pay CEP, in cash, the value of such Non-Conveyed Assets as set forth on Schedule 1.2(c) next to such Non-Conveyed Assets less the amount of any benefits received and net of any payments made by the Company with respect to such Non-Conveyed Assets.

Section 1.3 Effective Time. The effective time for purposes of this Agreement shall be as of 12:01 a.m., central time, on August 1, 2013 (the “Effective Time”).

(iii) any other amount specified herein or otherwise agreed upon by Sanchez and CEP in writing.

(i) If the effect of such adjustments results in CEP delivering additional Consideration to Sanchez either on or after the Closing, such adjustments shall be made to the Cash Consideration.

(ii) If the effect of such adjustments results in CEP delivering less Consideration to Sanchez on the Closing or Sanchez returning Consideration to CEP after the Closing, such adjustments shall be made in the following order (with an offset in full against each type of Consideration before offsetting against the next type of Consideration):

(a) First, to the Cash Consideration;

(b) Second, to the Common Unit Consideration; and

Sanchez shall respond in writing with any objections and proposed corrections within 30 days of receiving the Final Settlement Statement. If Sanchez does not respond to the Final Settlement Statement by signing or objecting in writing within such 30-day period, the statement will be deemed approved by Sanchez and final and binding between the Parties. If Sanchez timely notifies CEP of any objections to the Final Settlement Statement, the Parties shall undertake to agree with respect to the Post-Closing adjustment within 30 days thereafter. If the Parties are unable to so agree, either Party may refer the dispute to an Independent Expert in accordance with Article IV.

Section 2.6 Final Adjustments to Consideration. Within five Business Days after the Parties’ approval of the Final Settlement Statement, or the Independent Expert’s resolution of any disputes with respect thereto, as applicable:

(a) If the Consideration set forth in the Final Settlement Statement results in less consideration payable to Sanchez pursuant to Section 2.4(c)(ii), then Sanchez will pay to CEP, in accordance with Section 2.4(c)(ii), the amount of such difference (i.e., the amount of such adjustments to the Consideration agreed by the Parties or as determined by the Independent Expert and reflected in the Final Settlement Statement).

(b) If the Consideration set forth in the Final Settlement Statement results in more consideration payable to Sanchez pursuant to Section 2.4(c)(i), then CEP will pay to Sanchez, in accordance with Section 2.4(c)(i), the amount of such difference (i.e., the amount of such adjustments to the Consideration agreed by the Parties or as determined by the Independent Expert and reflected in the Final Settlement Statement).

ARTICLE III. REPRESENTATIONS AND WARRANTIES

Except for any matters that may affect title to the Leases or the Wells or that relate to the environment, as to which Sanchez makes no representations or warranties in this Section 3.1 or elsewhere in this Agreement, Sanchez represents and warrants to CEP that, as of the date hereof:

(a) Indemnified Claims. Subject to the further provisions hereof, from and after the Closing, CEP shall defend, protect, indemnify and hold Sanchez, its affiliates, and their respective partners, members, managers, directors, officers, employees, contractors and representatives (which additional parties, together with Sanchez, are hereinafter collectively referred to as the “Sanchez Indemnitees”) harmless from and against any and all Claims in any way arising from, out of or in connection with, or otherwise relating to:

Section 7.5 Negligence and Strict Liability. THE FOREGOING ASSUMPTIONS AND INDEMNIFICATIONS IN THIS ARTICLE VII SHALL APPLY WHETHER OR NOT THE CLAIM AROSE OUT OF THE SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE (BUT NOT GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), STRICT LIABILITY, LIABILITY WITHOUT FAULT, REGULATORY LIABILITY, STATUTORY LIABILITY, BREACH OF CONTRACT, BREACH OF WARRANTY, OR OTHER FAULT OR RESPONSIBILITY OF THE INDEMNIFIED PARTY.

Section 7.6 Claims Procedures. Promptly upon a Party becoming aware of any Claim with respect to which it believes it is entitled to indemnification hereunder (or would be entitled to indemnification hereunder but for the application of the Aggregate Indemnification Threshold), a Party (an “Indemnified Party”) shall notify the Party from whom indemnification is sought (the “Indemnifying Party”) in writing of the existence and nature of such Claim, the identity of any third party claimants and a description of the damages and the amount thereof relating to such Claim (the “Claim Notice”). Within 10 Business Days of receipt of a Claim Notice, the Indemnifying Party will provide written notice to the Indemnified Party that it accepts, contests or rejects the Claims identified in such Claim Notice. Any failure of the Indemnifying Party to provide such notice within such time period shall be deemed to be a rejection by such Indemnifying Party of such Claim and its responsibility for same. If the Indemnifying Party accepts the Claims identified in the Claim Notice, the Indemnifying Party shall pay the Indemnified Party the full amount of any amounts claimed no later than 10 Business Days after the Indemnifying Party responds to the Claim Notice. Subject to the limitations pursuant to Section 7.3 or Section 7.4, as applicable, the Indemnified Party shall be responsible for the defense of any Claim unless the Indemnifying Party, upon reasonable notice, requests that the defense of a Claim be tendered to the Indemnifying Party. If (i) the defense of a Claim is so tendered and within 10 Business Days thereafter such tender is accepted by the Indemnifying Party on the terms proposed by the Indemnified Party; or (ii) within 10 Business Days after the date on which the Claim Notice has been given pursuant to this Section 7.6, the Indemnifying Party shall acknowledge in writing to the Indemnified Party its obligation to provide an indemnity and assume the defense of the Claim, then, except as hereinafter provided, the Indemnified Party shall not, and the Indemnifying Party shall, have the right to contest, defend, litigate or settle such Claim. The Indemnified Party shall have the right to be represented by counsel at the Indemnified Party’s expense, subject to the limitations hereof, in any such contest, defense, litigation or settlement conducted by the Indemnifying Party. The Indemnifying Party shall lose its right to defend and settle the Claim if, after notice from the Indemnified Party concerning failure to diligently contest and defend the Claim, the Indemnifying Party shall fail to thereafter diligently contest and defend the Claim. So long as the Indemnifying Party has not lost its right or obligation to contest, defend, litigate and settle as herein provided, the Indemnifying Party shall have the exclusive right to contest, defend and litigate the Claim and shall have the exclusive right, in its discretion exercised in good faith, and upon the advice of counsel, to settle any such matter, either before or after the initiation of litigation, at such time and upon such terms as it deems fair and reasonable; provided, that at least five Business Days prior to any such settlement, written notice of its intention to settle shall be given to the Indemnified Party and the Indemnified Party shall have consented thereto, which

consent shall not be unreasonably withheld, conditioned or delayed. Subject to the applicable limitations in this Article VII, including the Indemnity Cap, all reasonable expenses (including without limitation reasonable attorneys’ fees) incurred by the Indemnifying Party in connection with the foregoing shall be paid by the Indemnifying Party. Notwithstanding the foregoing, in connection with any settlement negotiated by an Indemnifying Party, no Indemnified Party shall be required by an Indemnifying Party to (w) enter into a settlement or other similar agreement that prejudices the rights of the Indemnified Party, (x) enter into any settlement that does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the Indemnified Party of a release from all liability in respect of such claim or litigation, (y) enter into any settlement that attributes by its terms liability or wrongdoing to the Indemnified Party or (z) consent to the entry of any judgment that does not include as a term thereof a full dismissal of the litigation or proceeding with prejudice. No failure by an Indemnifying Party to acknowledge in writing its indemnification obligations under this Article VII or any other provision hereof shall relieve it of such obligations to the extent they exist. If the Indemnifying Party fails to accept a tender of, or assume, the defense of a Claim pursuant to this Section 7.6, or if, in accordance with the foregoing, the Indemnifying Party shall lose its right to contest, defend, litigate and settle such a Claim or if there is a legal conflict, the Indemnified Party shall have the right, without prejudice to its right of indemnification hereunder, in its discretion exercised in good faith and upon the advice of counsel, to contest, defend and litigate such Claim, and may settle such Claim, either before or after the initiation of litigation, at such time and upon such terms as the Indemnified Party deems fair and reasonable; provided, that the Indemnified Party will not settle such Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. If the Indemnified Party so contests, defends, litigates or settles a Claim for which it is entitled to indemnification hereunder as hereinabove provided, then, subject to the applicable limitations in this Article VII, including the Indemnity Cap, the Indemnified Party shall be reimbursed by the Indemnifying Party for the reasonable attorneys’ fees and other expenses of defending, contesting, litigating and/or settling the Claim which are incurred from time to time, forthwith following the presentation to the Indemnifying Party of itemized bills for said attorneys’ fees and other expenses.

Section 7.7 Subrogation. Following full indemnification as provided for hereunder, the Indemnifying Party shall be subrogated to all rights of the Indemnified Party with respect to all parties relating to the matter for which indemnification has been made and the Indemnified Party agrees upon the request from time to time or at any time from the Indemnifying Party to fully cooperate with the Indemnifying Party in exercising such subrogation rights; provided, however, that no such subrogation shall be provided to any Indemnifying Party in respect of any Claim not satisfied in full as a result of any of the limitations on indemnity contained in this Agreement as a result of the obligation of such Indemnifying Party in respect of such Claim.

Section 7.8 Insured Losses; Recoveries from Third Parties. The amount of any damages for which indemnification is provided hereunder shall be net of any duplicative amounts recovered by the Indemnified Party under insurance policies or from unaffiliated third parties with respect to such damages. If an Indemnified Party receives an amount under insurance coverage or from an unaffiliated third party with respect to damages at any time subsequent to any indemnification provided by an Indemnifying Party pursuant hereto, then such Indemnified Party shall promptly deliver such amount (up to the amount of the indemnification payment made to such Indemnified Party regarding such matter) to the Indemnifying Party;

provided, however, that such Indemnified Party shall be entitled to retain the amount of any payments made for costs or expenses incurred in connection with obtaining such payment. The obligation created by this Section 7.8 is an obligation to make repayment in the event of a recovery from a third party and shall not delay an Indemnified Party’s right to repayment from the Indemnifying Party hereunder.

Section 7.9 Characterization of Indemnification Payments. The Parties agree to treat for federal, state and local income tax purposes any payment with respect to an indemnified Claim as an adjustment to the Consideration, unless otherwise required by applicable Legal Requirement or as agreed by the Parties.

Section 7.10 Exclusive Remedies. After the Closing, and except for fraud or any non-monetary, equitable relief to which a Party may be entitled, the rights and remedies set forth in this Article VII shall constitute the sole and exclusive rights and remedies of the Parties under or with respect to the subject matter of this Agreement.

ARTICLE VIII. TAX MATTERS

Section 8.1 Payment of Taxes: Preparation of Tax Returns.

(a) Sanchez shall file all Tax Returns required to be filed by or with respect to the Company or the Company Assets for a Pre-Closing Tax Period that are required to be filed prior to or on the Closing Date. CEP shall prepare and timely file all other Tax Returns required to be filed by or with respect to the Company and the Company Assets. CEP shall provide to Sanchez for its review a draft of each such Tax Return of the Company for any Taxable period ending on or before the Closing Date or for any Taxable period beginning before and ending after the Closing Date no later than 10 days prior to the due date (including extensions) of such Tax Return, and CEP shall make such changes to such draft Tax Return as Sanchez may reasonably request.

(b) Sanchez shall, except to the extent the Taxes have been taken into account in determining the Consideration, pay, and shall indemnify and hold CEP and its Affiliates harmless from and against all, Taxes owed and payable by the Company or with respect to the Company Assets at any time prior to or on the Closing Date. Sanchez shall indemnify and hold harmless CEP and its affiliates from and against all Taxes with respect to the Company or the Company Assets and attributable to any Pre-Effective Time Tax Period or portion of any Straddle Period prior to and including the Effective Time. CEP shall pay or be responsible for all other Taxes owed with respect to the Company or any of the Company Assets.

(c) For purposes of this Agreement, liability for Taxes with respect to the Company or the Company Assets with respect to any Straddle Period shall be apportioned as follows: property and similar ad valorem Taxes shall be apportioned on a ratable daily basis, and all other Taxes shall be apportioned based on an interim closing of the books of the Company as of the end of the Effective Time.

(d) Notwithstanding the above, CEP and Sanchez acknowledge that the Company is a member of Sanchez’s combined group for Texas franchise tax purposes and that Sanchez will prepare the Texas franchise tax returns of the Company for all periods that include the Company as a member of Sanchez’s combined group and pay all the Texas franchise taxes related thereto.

(e) For purposes of this Agreement the following terms shall have the assigned meanings:

(i) “Pre-Closing Tax Period” means any Tax period ending on or before the Closing Date.

(ii) “Pre-Effective Time Tax Period” means any Tax period ending on or before the Effective Time.

(iii) “Straddle Period” means any Tax period that includes but does not end at the Effective Time.

(iv) “Tax Returns” means any report, return, election, document, estimated tax filing, declaration, claim for refund, information returns, or other filing provided to any Governmental Authority including any schedules or attachments thereto and any amendment thereof.

(v) “Taxes” means all taxes, assessments, charges, duties, fees, levies, imposts or other similar charges imposed by a Governmental Authority, including all income, franchise, profits, margins, capital gains, capital stock, transfer, gross receipts, sales, use, transfer, service, occupation, ad valorem, real or personal property, excise, severance, windfall profits, customs, premium, stamp, license, payroll, employment, social security, unemployment, disability, environmental, alternative minimum, add-on, value-added, withholding and other taxes, and assessments, charges, duties, fees, levies, imposts or other similar charges of any kind, and all estimated taxes, deficiency assessments, additions to tax, penalties and interest with respect to taxes, whether disputed or otherwise.

Section 8.2 Transfer Taxes. Notwithstanding Section 8.1, all excise, sales, use, transfer (including real property transfer), stamp, documentary, filing, recordation and other similar taxes, together with any interest, additions or penalties with respect thereto and any interest in respect of such additions or penalties, resulting directly from the sale and transfer by Sanchez to CEP of the Assigned Equity (the “Transfer Taxes”), shall be borne by CEP. CEP shall indemnify and hold harmless Sanchez and its affiliates from, against and in respect of any such Transfer Taxes. Notwithstanding Section 8.1, which shall not apply to Tax Returns relating to Transfer Taxes, any Tax Returns that must be filed in connection with Transfer Taxes shall be prepared and filed when due by the Party primarily or customarily responsible under the applicable local Legal Requirement for filing such Tax Returns, and such Party will use its commercially reasonable efforts to provide such Tax Returns to the other Party at least 10 days prior to the Due Date for such Tax Returns.

Section 8.3 Amendment of Tax Returns. Except to the extent required by Legal Requirement, CEP shall not, and shall cause the Company and any controlled affiliate of either of them not to, without the prior written consent of Sanchez (which consent shall not be unreasonably withheld), amend any Tax Return of the Company for any period or portion thereof ending on or before the Closing Date.

Section 8.4 Maintenance of Books and Records. Until the applicable statute of limitations (including periods of waiver) has expired for any Tax Returns filed or required to be filed by the Company covering the periods, or portions thereof, ending on or before the Closing Date, CEP shall retain all books and records that Sanchez delivers to CEP at the Closing relating to Taxes of the Company in existence on the Closing Date.

Section 8.5 Assistance and Cooperation. The Parties agree that, after the Closing Date:

(a) Sanchez shall use its commercially reasonable efforts to assist (and cause its affiliates to reasonably assist) CEP in preparing any Straddle Period Tax Returns;

(b) The Parties shall cooperate fully in preparing for any pending or threatened audits, adjustments, assessments or subsequent proceedings (each, a “Tax Audit”), or disputes with taxing authorities, relating to any Tax Returns or Taxes of the Company, including providing access to relevant books and records relating to Taxes in accordance with Section 8.4;

(c) The Parties shall make available to each other and to any Taxing authority as reasonably requested all relevant books and records relating to Taxes in connection with any Tax Audit;

Section 8.6 Tax Proceedings. If a claim shall be made by any Tax authority in respect of the Company for a Tax period (or portion thereof) ending on or prior to the Closing Date, CEP shall promptly give written notice to the Sanchez of such claim in accordance with Section 10.10. The failure of CEP to give such notices shall relieve Sanchez from its indemnification obligations hereunder, but only to the extent it is actually prejudiced by such failure. With respect to any Tax claim against the Company for which Sanchez may be liable pursuant to this Article VIII, Sanchez shall control all proceedings and may make all decisions taken in connection with such Tax claim (including selection of counsel) at Sanchez’s expense and pay all Taxes related thereto; provided, however, that if the resolution of any portion of such a Tax claim would increase the Taxes of CEP, the Company or their direct or indirect owners for a Tax period after the Closing Date, Sanchez shall give written notice thereof to CEP, and CEP shall be entitled to participate in the proceedings taken in connection with such portion of such Tax claim. CEP shall control at its own expense all proceedings taken in connection with any Tax claim relating to the Company for a Straddle Period and in connection with any Tax claim relating to the Company for a Tax period beginning after the Closing Date; provided, however, that if the resolution of any portion of such a Tax claim would reasonably be expected to

adversely affect Sanchez, CEP shall give written notice thereof to the Sanchez, and Sanchez shall be entitled to participate in the proceedings taken in connection with such portion of such Tax claim. A Party shall promptly notify the other Party if it decides not to control the defense or settlement of any Tax claim for a Tax period (or portion thereof) ending on or prior to the Closing Date which it is entitled to control pursuant to this Agreement, and the other Party shall thereupon be permitted to defend and settle such proceeding without prejudice.

ARTICLE IX. CERTAIN POST-CLOSING COVENANTS

CEP will retain the Records delivered to it hereunder and Sanchez shall have the right to review the Records during standard business hours upon reasonable notice, in each case, for seven years after the Closing with respect to tax Records and four years after the Closing with respect to other Records.

Section 9.2 Suspense Accounts. Sanchez is retaining all revenue suspense accounts maintained by Sanchez that are scheduled on Schedule 9.2 and have not been paid because of title defects, or because such persons cannot be located or their identity is unknown or other causes and will administer the payment of such funds after the Closing upon the resolution of such matters.

Section 9.3 Successor Operator. CEP acknowledges and agrees that, on and after the Closing, an affiliate of Sanchez shall remain the operator of the Company Assets with respect to the portions thereof which such affiliate presently operates.

CEP further agrees, if CEP applies to have its Common Units traded on any national securities exchange other than the NYSE MKT, it will include in such application all of the Common Units issued to Sanchez on the Closing Date and will take such other action as is necessary to cause all of such units to be listed on such other national securities exchange as promptly as possible. CEP will take all action reasonably necessary to continue the listing and trading of its Common Units on a national securities exchange and will comply in all respects with CEP’s reporting, filing and other obligations under the bylaws or rules of such national securities exchange.

Section 9.6 Issuance of Additional Class A Units.

Section 9.8 Further Assurances. From time to time after Closing, each Party shall execute, acknowledge and deliver to the other Party such further instruments and take such other action as may be reasonably requested in order more effectively assure to the other the full beneficial use and enjoyment of the Company Assets and to accomplish the purposes of the transactions contemplated by this Agreement. Upon Sanchez’s written request, CEP shall use commercially reasonable efforts to cause any guarantees by SEP or its affiliates under the Leases to be released.

Section 9.9 Release of Stifel. Sanchez hereby (a) disclaims any reliance upon Stifel Nicolaus & Company, Incorporated, financial advisor to CEP, or its officers, directors, employees, attorneys or affiliates (the “Stifel Parties”) with respect to the negotiation, execution or performance of this Agreement or any representation or warranty made by the Stifel Parties in, in connection with, or as an inducement to this Agreement; (b) agrees that all claims, obligations, liabilities, demands, causes of action or obligations (each, an “Action”) that may be based upon, arise under or relate to this Agreement or its negotiation, execution or performance may not be made against the Stifel Parties to the extent that such Actions are initiated by Sanchez (but excluding for the avoidance of doubt any Action which is initiated by another security holder of CEP and which Sanchez may elect to participate in its capacity as a security holder of CEP); (c) waives and releases all Actions against the Stifel Parties which are initiated by Sanchez (but excluding for the avoidance of doubt any Action which is initiated by another security holder of CEP and which Sanchez may elect to participate in its capacity as a security holder of CEP) in connection with this Agreement and the transactions contemplated hereby; and (d) agrees that Stifel will be a third-party beneficiary of this Section 9.9.
