Section 2.1 Certain Title and Environmental Matters.

(a) Within five (5) days following receipt, but in any event not later than thirty (30) days prior to the spudding of the applicable Farmout Well (other than the Initial Wells) or Elected Option Well, EP Energy will obtain and deliver to Partner a drill site title opinion for such Farmout Well or Elected Option Well and Partner will have such title examination and approval rights as set forth in Article IV.A. of the EP/Apollo JOA. Such rights will be Partner’s sole and exclusive remedy with respect to title of any Farmout Wells (other than the Initial Wells) or Elected Option Wells (other than Partner’s right to exclude Farmout Wells from the Proposed Second Tranche Drilling Program pursuant to Section 4.2(c) and any claim validly asserted with respect to the special warranty set forth herein or in any of the Assignments or the breach by EP Energy or its Affiliates of this Section 2.1(a) or any of its representations in Section 11.1(d), Section 11.1(g), Section 11.1(h), Section 11.1(j), Section 11.1(l), Section 11.1(o), Section 11.1(p) or Section 11.1(t)). Partner acknowledges that it has completed its title review of the Initial Wells and agrees that it will not assert and hereby waives any and all title claims with respect to the Initial Wells (other than any claim validly asserted with respect to the special warranty set forth herein or in the Assignment or the breach by EP Energy or its Affiliates of this Section 2.1(a) or any of its representations in Section 11.1(d), Section 11.1(g), Section 11.1(h), Section 11.1(j), Section 11.1(l), Section 11.1(o), Section 11.1(p) or Section 11.1(t)).

(b) The Parties agree and acknowledge that:

(i) Any Environmental Condition in respect of the Development Interests or Leases relating to or arising from (A) any operations or activities conducted in connection with an Approved Drilling Program or any Elected Option Well or (B) any other operation or activity (in each case with respect to subsection (A) and (B), in which both Parties are participating, or obligated to participate, in) will, subject to Partner’s rights with respect to a breach by EP Energy or its Affiliates of Section 3.1(d) (solely to the extent not subject to the limitation of liability under Section 3.3) or its representations in Section 11.1(n) solely with respect to Environmental Conditions that existed prior to the commencement of any Development Operation, be borne by the Parties in accordance with their respective Working Interest share.

(ii) Any Environmental Condition in respect of the Development Interests or Leases relating to or arising from any operation, condition or activity in which EP Energy participates and in which Partner does not participate (or is not obligated to participate) in, including pursuant to the terms of this Agreement, will be borne solely by EP Energy.

(iii) Any Environmental Condition in respect of the Development Interests or Leases relating to or arising from any operation, condition or activity by EP Energy prior to the Execution Date (other than any Environmental Condition that is the subject of Section 2.1(b)(i)) will be borne solely by EP Energy (together with the Environmental Conditions described in Section 2.1(b)(ii), the “Retained Environmental Conditions”).

(i) From and after submission by EP Energy to Partner of the Proposed Second Tranche Drilling Program in accordance with Section 4.2 and up to and including the 45^th day after Partner’s receipt of the Proposed Second Tranche Drilling Program, but subject to the other provisions of this Section 2.1(c) and subject to any applicable confidentiality restrictions and other contractual or legal restrictions (each of which EP Energy shall use its commercially reasonable efforts to procure waivers from the holders thereof; provided that EP Energy shall not be obligated to pay the holders thereof any monies to obtain such waiver), EP Energy shall permit Partner and its authorized representatives (“Partner’s Representatives”) reasonable access, during normal business hours, to the Well Locations included in the Proposed Second Tranche Drilling Program to the extent necessary to conduct an environmental assessment. Any conclusions made from any examination done by Partner or any Partner’s Representative shall result from Partner’s own independent review and judgment. Partner’s inspection right with respect to the Environmental Condition of the applicable Well Locations shall be limited to undertaking a Phase I Environmental Site Assessment of the applicable Well Locations conducted by Environmental Resources Management, TRC Environmental Corporation or another reputable environmental consulting or engineering firm approved in advance in writing by EP Energy (such approval not to be unreasonably withheld, conditioned or delayed). The inspection undertaken by the designated environmental consulting or engineering firm may include only visual inspections and record reviews relating to the applicable Well Locations. In conducting such inspection, Partner shall not operate any equipment or conduct any testing or sampling of soil, groundwater or other materials (including any testing or sampling for Hazardous Substances, Hydrocarbons or naturally occurring radioactive materials). EP Energy or EP Energy’s designee shall have the right to be present during any stage of the assessment. Partner shall give EP Energy reasonable prior written notice before gaining physical access to any of the applicable Well Locations, and EP Energy or its designee shall have the right but not the obligation to accompany Partner and Partner’s Representatives whenever Partner or Partner’s Representatives gain physical access to any applicable Well Locations.

(ii) Partner shall coordinate its access rights, environmental property assessments and physical inspections of the applicable Well Locations with EP Energy and all applicable Third Parties, as applicable, to minimize any

inconvenience to or interruption of the conduct of business by EP Energy or any such Third Party. Partner shall abide by EP Energy’s safety rules, regulations and operating policies (to the extent provided to Partner in writing and in advance of any environmental assessment conducted by or on behalf of Partner) while conducting its environmental assessment of the applicable Well Locations. Partner hereby indemnifies, defends, and holds harmless each EP Energy Indemnified Party from and against any and all Liabilities arising out of, resulting from or relating to any field visit, environmental assessment or other due diligence activity conducted by Partner or any of Partner’s Representatives with respect to the applicable Well Locations, EVEN IF SUCH LIABILITIES ARISE OUT OF OR RESULT FROM, IN WHOLE OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF ANY EP ENERGY INDEMNIFIED PARTY, EXCEPTING ONLY LIABILITIES (A) TO THE EXTENT ACTUALLY RESULTING FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY EP ENERGY INDEMNIFIED PARTY, OR (B) ARISING FROM EXISTING ADVERSE ENVIRONMENTAL CONDITIONS THAT MAY BE DISCOVERED BY PARTNER BUT THAT ARE NOT ADVERSELY AFFECTED BY PARTNER’S ACTIVITIES.

(iii) Partner acknowledges that any entry into EP Energy’s offices or onto the applicable Well Locations shall be at Partner’s sole risk, cost and expense, and, subject to the terms hereof, that none of the EP Energy Indemnified Parties shall be liable in any way for any injury, loss or damage arising out of such entry that may occur to Partner or any of Partner’s Representatives pursuant to this Agreement, except to the extent actually resulting from (A) the gross negligence or willful misconduct of any EP Energy Indemnified Party or (B) existing adverse environmental conditions that may be discovered by Partner but that are not adversely affected by Partner’s activities. Partner hereby fully waives and releases any and all Liabilities against all of the EP Energy Indemnified Parties for any injury, death, loss or damage to any of Partner’s Representatives or their property in connection with Partner’s due diligence activities, EVEN IF SUCH LIABILITIES ARISE OUT OF OR RESULT FROM, IN WHOLE OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF ANY EP ENERGY INDEMNIFIED PARTY, EXCEPTING ONLY LIABILITIES (A) TO THE EXTENT ACTUALLY RESULTING FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY EP ENERGY INDEMNIFIED PARTY, OR (B) ARISING FROM EXISTING ADVERSE ENVIRONMENTAL CONDITIONS THAT MAY BE DISCOVERED BY PARTNER BUT THAT ARE NOT ADVERSELY AFFECTED BY PARTNER’S ACTIVITIES.

(iv) Partner agrees to promptly provide EP Energy, but in no event less than five days after receipt or creation thereof by Partner or any of Partner’s

Representatives (including Partner’s environmental consulting or engineering firm), copies of all final environmental reports prepared by Partner or any of Partner’s Representatives, which contain data collected or generated from Partner’s or any of Partner’s Representatives’ due diligence with respect to the applicable Well Locations. EP Energy shall not be deemed by its receipt of said documents or otherwise to have made any representation or warranty, express, implied or statutory, as to the condition of the applicable Well Locations or to the accuracy of said documents or the information contained therein. Neither Partner nor Partner’s Representatives shall be deemed by its or their delivery of said documents or otherwise to have made any representation or warranty, express, implied or statutory, as to the condition of the applicable Well Locations or to the accuracy of said documents or the information contained therein.

(v) Upon completion of Partner’s environmental assessment, to the extent actually caused by the actions of Partner or any of Partner’s Representatives, Partner shall at its sole cost and expense and without any cost or expense to EP Energy or any of its Affiliates (i) repair all damages done to any applicable Well Location in connection with Partner’s or any of Partner’s Representatives’ environmental assessment (including due diligence conducted by Partner’s environmental consulting or engineering firm), (ii) restore the applicable Well Locations to the approximate same condition as, or better condition than, they were prior to commencement of any such environmental assessment, and (iii) remove all equipment, tools or other property brought onto the applicable Well Locations in connection with such environmental assessment. Any surface disturbance to the applicable Well Locations (including the leasehold associated therewith) resulting from such due diligence will be promptly corrected by Partner. For avoidance of doubt, to the extent that Partner’s inspection of the applicable Well Locations is limited to a visual inspection in accordance with Section 2.1(c)(i), then any repair or restoration work as set forth above shall be limited to repair, restoration or correction associated with any surface damage or disturbance caused by Partner or the Partner Representatives in connection with such diligence.

(d) Partner may elect by written notice to EP Energy within 10 days of Partner’s receipt of the initial AFE for a Farmout Well or Elected Option Well (as applicable) to withdraw from participation in such Farmout Well or Elected Option Well (as applicable) in the event that a MAE Event is then occurring. EP Energy shall provide Partner written notice promptly (but in any event within five Business Days) of the occurrence of any MAE Event.

Section 2.2 Farmout Wells. The Wells drilled, or to be drilled, on Well Locations included in an Approved Drilling Program and limited to the Target Bench for such Wells as set forth in the applicable Approved Drilling Program, including the Initial Wells, are hereinafter referred to collectively as, the “Farmout Wells” and each, individually, a “Farmout Well”.

Section 2.3 Assignment. Partner shall, for all purposes, be deemed to have received the right to own the Conveyed Interest upon the First Funding Date with respect to such Farmout Well or Elected Option Well (as applicable). Subject to the terms and conditions of this Agreement (including Section 2.5), so long as Partner is not a Defaulting Party (for the avoidance of doubt, EP Energy shall only be permitted to withhold Assignments owed to Partner hereunder during the Default Period and EP Energy shall promptly deliver any Assignments earned by Partner upon the expiration of the Default Period), EP Energy will execute and deliver to Partner an Assignment (with special warranty of title by, through or under EP Energy and its Affiliates, but not otherwise) conveying to Partner the Initial Partner Working Interest Share with respect to such Farmout Well or the Residual Partner Working Interest Share with respect to such Elected Option Well (as applicable) in (a) the wellbore of any such Well limited to the applicable Target Bench; (b) any associated right, title and interest in and to the oil and gas leases described on the attached Exhibit B (as such exhibit may be amended from time to time pursuant to Section 2.8) (all such oil and gas leases, together with any lands pooled or unitized therewith, the “Leases”), insofar and only insofar as said Leases are necessary to own, operate, maintain and/or produce such Farmout Well or Elected Option Well (as applicable) and limited to the applicable Target Bench and associated Wellhead Equipment (including rights of ingress and egress to and from the applicable Well and associated Wellhead Equipment, each (if any) as set forth within such Leases), excepting all other right, title and interest in the Leases and (c) all equipment, machinery, fixtures and other personal, movable and mixed property, operational and nonoperational, known or unknown, located within the wellbore of such Farmout Well or Elected Option Well (as applicable) and outside of such wellbore up to and including the wellhead allocation meter for such Farmout Well or Elected Option Well (the “Wellhead Equipment”) (such interest conveyed for each Farmout Well or Elected Option Well as described above and more particularly in the applicable Assignment, the “Conveyed Interest” and, collectively with respect to all such Farmout Wells and/or Elected Option Wells, the “Conveyed Interests”); provided, however, that for the avoidance of doubt, Partner will not receive a conveyance of any rights beyond the wellhead allocation meter of any Farmout Well or Elected Option Well (as applicable). From and after the Completion of any Farmout Well or Elected Option Well, to the extent requested by Partner in writing, the Parties shall execute any and all correction Assignments reasonably necessary to more correctly describe any Farmout Well or Elected Option Well covered by any Assignment. Excepting all other right, title and interest in the Leases and any associated Wellhead Equipment, the entirety of EP Energy’s and its Affiliates’ right, title and interest in each such Farmout Well or Elected Option Well (as applicable and including any Well Location) and any such associated right, title and interest in and to the Leases, insofar and only insofar as said Leases are necessary to own, operate, maintain and/or produce such Farmout Well, Elected Option Well or Well drilled on such Well Location (as applicable) (in each case, limited to the applicable Target Bench), and any associated Wellhead Equipment (in each case) immediately prior to the Execution Date is hereinafter referred to as a “Development Interest”. The fully executed Assignment for each Farmout Well or Elected Option Well (as applicable) will be delivered to Partner contemporaneously with the First Funding Date for such Well. Notwithstanding anything herein to the contrary, without Partner’s prior written consent, EP Energy shall not establish or amend any pools or units with respect to any Well Location that would cause a decrease in the Net Revenue Interest (without a corresponding decrease in the Working Interest) or increase in the Working Interest (without a corresponding increase in the Net Revenue Interest) of EP Energy with respect to any Well Location set forth in Exhibit A.

Section 2.4 Mortgage and Lien Releases. (a) At least 90 days prior to the spud of any Elected Option Well or (b) with respect to the Farmout Wells, on or prior to the Execution Date (or with respect to the Specified Well, within five Business Days of the Execution Date), with respect to the Well Locations, Farmout Wells or Elected Option Wells (as applicable) identified in the First Tranche Drilling Program, EP Energy will deliver to Partner recordable lien releases (in forms reasonably acceptable to Partner) executed by the applicable holders of any then-existing indebtedness of EP Energy or any of its Affiliates that encumbers the Conveyed Interests (such debt, as the same may be modified, amended or supplemented in the future, “Existing Secured Debt”) pursuant to which such holders release the liens covering the Conveyed Interests that secure such Existing Secured Debt, and have the holders of Existing Secured Debt agree to execute recordable lien releases in the future releasing any liens covering any Conveyed Interests assigned (or to be assigned) to Partner as provided herein that secure such Existing Secured Debt, including all liens securing the Existing Secured Debt that cover any Well Locations or Farmout Wells in the Second Tranche Drilling Program, if applicable, (which lien release shall be deliverable prior to the spud of the first Farmout Well included in the Second Tranche Drilling Program). Within 5 Business Days following delivery by such holders of the applicable lien releases, EP Energy will record such lien releases provided to Partner in the preceding sentence in the applicable county recording office(s) and deliver a file-stamped copy to Partner upon receipt by EP Energy. Notwithstanding anything to the contrary herein, until the applicable lien releases for the Specified Well as required by this Section 2.4 has been delivered by EP Energy to Partner, Partner shall not be required to make any payment with respect to the Specified Well pursuant to Section 5.2 and EP Energy shall not be required to assign the Specified Well pursuant to Section 2.3.

Section 2.5 Reversion.

(a) With respect to each Conveyed Interest in a Well Group, at and upon the Partner Working Interest Reduction Point for all of the Wells included in such Well Group, such Conveyed Interest will automatically be reduced to the Residual Partner Working Interest Share (effective as of the Partner Working Interest Reduction Point) in such Wells and the remaining portion of such Conveyed Interest in such Wells will be automatically reverted to EP Energy (with such occurrence referred to herein as, “Reversion”); provided that, for the avoidance of doubt, Partner’s Working Interest will not be reduced or bear the impact of any after payout reduction in Working Interests arising from that certain letter agreement, dated August 17, 2007 (the “Lone Star Letter Agreement”), by and between Lone Star Production Company and Stonegate Production Company, LLC, as amended, or any other similar “payout” interests, in each case, existing as of the Execution Date.

(b) Upon the Partner Working Interest Reduction Point for the Wells included in a Well Group, Partner agrees to take all actions reasonably requested by EP Energy to reflect the occurrence of Reversion, including (i) executing, acknowledging and delivering an acknowledgement reflecting that the Partner Working Interest Reduction Point for such Wells has occurred and that the applicable Conveyed Interest has been reduced to the Residual Partner Working Interest Share (effective as of the date of Reversion) and providing a special warranty by, through or under Partner and its Affiliates but not otherwise as to the interest reverted to EP Energy (being an undivided interest in the applicable Conveyed

Interest equal to the difference between the Initial Partner Working Interest Share and the Residual Partner Working Interest Share) to be filed of record in the counties in which such Wells are located and (ii) executing and delivering letters-in-lieu, revised division orders and any other documents or instruments reasonably requested by EP Energy to document such event. If Partner fails to execute and deliver any document described in the preceding sentence within 10 Business Days of EP Energy’s written request and such Partner Working Interest Reduction Point has occurred (as agreed by the Parties or finally determined pursuant to Section 2.6(b)) subject to Section 2.7(a), EP Energy is hereby authorized to (A) execute, notarize and file of record an acknowledgement (which will be effective without the need for execution thereof by Partner), acknowledging that the Partner Working Interest Reduction Point has occurred and that the applicable Conveyed Interest has been reduced to the Residual Partner Working Interest Share (effective as of the date of Reversion) and (B) execute and deliver, on behalf of Partner, to applicable Third Parties letters-in-lieu, revised division orders and any other documents or instruments to document such event. For the avoidance of doubt, the reduction of each Conveyed Interest to the Residual Partner Working Interest Share will be effective upon the occurrence of the Partner Working Interest Reduction Point for the Wells included in the applicable Well Group and will not be conditioned upon or dependent on the execution or filing of any of the documents described in this Section 2.5(b) or any other documentation.

Section 2.6 IRR Calculation.

(a) EP Energy will calculate the IRR on a Well Group basis. Upon the occurrence of the applicable Partner Working Interest Reduction Point for the Wells in any Well Group, EP Energy will deliver to Partner a statement (a “Final IRR Statement”) prepared by EP Energy showing the date the Partner Working Interest Reduction Point for such Wells in such Well Group occurred. Such Final IRR Statement will be accompanied by reasonable supporting documentation with respect to EP Energy’s calculation. As soon as practicable, and in any event within 30 days after receipt of such Final IRR Statement, Partner will deliver to EP Energy a written report containing any proposed changes to the calculation of the IRR in such Final IRR Statement and an explanation of any such changes and the reasons therefor (the “Dispute Notice”). Any changes with respect to such Final IRR Statement not so specified in such Dispute Notice will be deemed waived and EP Energy’s determinations with respect to all such elements of the calculation of the IRR in such Final IRR Statement that are not addressed specifically in such Dispute Notice will prevail. If Partner fails to timely deliver a Dispute Notice to EP Energy containing changes Partner proposes to be made to a Final IRR Statement, then such Final IRR Statement as delivered by EP Energy and the date that the applicable Partner Working Interest Reduction Point occurred set forth therein will be deemed to be correct and mutually agreed upon by the Parties, and will be final and binding on the Parties and not subject to further audit or arbitration.

(b) If EP Energy and Partner are unable to resolve the matters addressed in any Dispute Notice within 30 days after the delivery of such Dispute Notice, then either EP Energy or Partner may request that the Houston office of Deloitte Touche Tohmatsu Limited or such other Person as the Parties may mutually select (such person as selected pursuant

to the foregoing or selected pursuant to the proviso to this sentence, the “Accounting Arbitrator”) to decide such matters set forth in such Dispute Notice; provided that if Deloitte Touche Tohmatsu Limited or any other Person selected by the Parties refuses to serve or if the Parties are unable to agree on any other Person to serve as Accounting Arbitrator, then the Houston office of the American Arbitration Association shall appoint the Accounting Arbitrator. Each of EP Energy and Partner will, within 10 Business Days after the agreement by the Accounting Arbitrator to serve, summarize its position with regard to such dispute in a written document of 20 pages or less and submit such summaries to, together with the Dispute Notice, the Final IRR Statement and any other documentation such Party may desire to submit. Within 20 Business Days after receiving the Parties’ respective submissions, the Accounting Arbitrator will render a decision choosing either EP Energy’s position or Partner’s position with respect to each matter addressed in any Dispute Notice, based on the materials submitted to the Accounting Arbitrator as described above, and in accordance with this Agreement. Any decision rendered by the Accounting Arbitrator pursuant to this Section 2.6(b) with respect to a Final IRR Statement will be final, conclusive and binding on EP Energy and Partner and will be enforceable against the Parties in any court of competent jurisdiction. The costs and expenses of the Accounting Arbitrator will be borne one-half by Partner and one-half by EP Energy. For the avoidance of doubt, Partner will continue to be paid proceeds for its Entitlement with respect to such Well Group based on the Initial Partner Working Interest Share until the Parties agree on the date such Partner Working Interest Reduction Point occurred or such date is finally determined pursuant to this Section 2.6. Upon final determination of the date of Reversion, Partner will reimburse EP Energy for any additional proceeds received in excess of its Working Interest share of proceeds (if any) and, without duplication, EP Energy shall be entitled to immediately set off such amount owed by Partner against any other proceeds that may be due to Partner (other than any proceeds attributable to Partner Production produced after the date of a Permitted Pledge Transfer with respect to Farmout Wells or Elected Option Wells (as applicable) included in such Permitted Pledge Transfer) and if such amount owed by Partner is set off against proceeds due to Partner with respect to any other Well Group, such proceeds shall be deemed to have been received by Partner as of the date of the set-off for the purpose of the IRR calculation with respect to such other Well Group.

Section 2.7 Power of Attorney.

(a) In furtherance of Section 2.5(b), if and only if Partner fails to timely execute, acknowledge and deliver the acknowledgement or any other instrument required to be executed, acknowledged and delivered pursuant to Section 2.5(b) within 10 Business Days of EP Energy’s written request (and, for the avoidance of doubt, such Partner Working Interest Reduction Point has occurred (as agreed by the Parties or finally determined pursuant to Section 2.6(b))), Partner makes, constitutes, and appoints any officer of EP Energy, in such capacity, as its true and lawful attorney-in-fact for Partner and in its name, place, and stead and for its limited use and benefit, to sign, execute, certify, acknowledge, swear to, file, and record any instrument described in Section 2.5(b) that is deemed necessary by EP Energy in its reasonable discretion to document the Reversion. Partner gives such attorney-in-fact full power and authority to do and perform each and every act or thing whatsoever

requisite or advisable to be done in connection with documenting the Reversion as fully as Partner might or could do personally, and ratifies and confirms all that any such attorney-in-fact shall lawfully do or cause to be done by virtue of the limited power of attorney expressly granted hereby. The limited power of attorney expressly granted pursuant hereto is a special power of attorney, coupled with an interest, and is irrevocable, and shall survive the insolvency, bankruptcy, dissolution or cessation of existence of Partner.

(b) In furtherance of Section 2.3, if and only if EP Energy fails to timely execute, acknowledge and deliver any Assignment required to be executed, acknowledged and delivered pursuant to Section 2.3 within 10 Business Days of Partner’s written request (and, for the avoidance of doubt, such Partner is not a Defaulting Party and such assignment is required under Section 2.3), EP Energy makes, constitutes, and appoints any officer of Partner, in such capacity, as its true and lawful attorney-in-fact for EP Energy and in its name, place, and stead and for its limited use and benefit, to sign, execute, certify, acknowledge, swear to, file, and record the Assignment to document the assignment of the Conveyed Interests. EP Energy gives such attorney-in-fact full power and authority to do and perform each and every act or thing whatsoever requisite or advisable to be done in connection with documenting the assignment of the Conveyed Interests as fully as EP Energy might or could do personally, and ratifies and confirms all that any such attorney-in-fact shall lawfully do or cause to be done by virtue of the limited power of attorney expressly granted hereby. The limited power of attorney expressly granted pursuant hereto is a special power of attorney, coupled with an interest, and is irrevocable, and shall survive the insolvency, bankruptcy, dissolution or cessation of existence of EP Energy.

Section 2.8 Update to Exhibit B. EP Energy may amend Exhibit B from time to time to incorporate any oil and gas leases located within the Development Area Boxes and acquired by EP Energy after the Execution Date. Without limiting the foregoing, prior to the earlier of (a) the date of approval of the Proposed Second Tranche Drilling Program by Partner or (b) the date that is 10 Business Days prior to the Second Tranche Approval Deadline, EP Energy shall amend Exhibit B to incorporate any of EP Energy’s oil and gas leases within the Development Area Boxes (taking into effect any applicable amendment to the description of the Development Area Boxes contained in the Proposed Second Tranche Drilling Program) that have not been added to Exhibit B previously.

(e) During the term of this Agreement, within 30 days following the execution of any new Material Contract or Marketing Transaction or any other material contract entered into for the performance of services or provision of equipment, supplies or other materials (including any work orders or confirmations issued under such contracts) (each such material contract, together with any work orders or confirmation issued under such contract, an “MSA”) related to the Development Operations (in each case, a “Development Operations Contract”), except for any contract or information contained therein that cannot be disclosed to Partner as a result of confidentiality obligations to Third Parties (provided that EP Energy shall use commercially reasonable efforts to seek a waiver of such obligations with respect to Partner), EP Energy shall provide Partner an executed copy of such new Development Operations Contract; provided that with respect to any MSA, EP Energy shall only be required to make such MSA available for Partner’s review and copy. Any credit or other saving attributable to the Development Interests for entering into any such Development Operations Contracts shall be shared on a proportionate basis between EP Energy and Partner.

Section 3.3 Liability of Operator. Notwithstanding anything herein to the contrary, but without limiting Partner’s right to indemnification under this Agreement and subject to the last sentence of this Section 3.3, in no event will EP Energy (or any of EP Energy’s Affiliates) serving

as operator hereunder or under any JOA or serving as Marketer hereunder have any Liability as operator or Marketer for any Liability sustained or incurred in connection with the conduct of any Development Operation, Marketing Transaction or any breach of any provision regarding the standard of performance of an operator or Marketer insofar as such performance standards relate to the conduct of Development Operations or Marketing Transactions, respectively, EVEN IF SUCH LIABILITY AROSE IN WHOLE OR IN PART FROM THE ACTIVE, PASSIVE, SOLE OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF EP ENERGY OR ITS AFFILIATES, OTHER THAN IF SUCH CLAIM, DAMAGE, LOSS OR LIABILITY AROSE FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF EP ENERGY OR ANY OF ITS AFFILIATES OR ANY EMPLOYEE OF EP ENERGY OR ANY OF ITS AFFILIATES; it being understood by each Party that any such claim, damage, loss or Liability (other than that caused by the gross negligence or willful misconduct of EP Energy or its Affiliates or any employee of EP Energy or any of its Affiliates), will be borne severally by the Parties (including the operator or Marketer) in proportion to their interests in the operations giving rise to such Liability (and if such operations are conducted prior to the execution and delivery of an Assignment with respect to a Well in which Partner has elected (or is deemed to have elected) to participate, Partner will bear its Initial Partner Working Interest Share of such Liability related to such Development Interest). Notwithstanding the foregoing, but subject to Section 3.5(b), EP Energy (and any of EP Energy’s Affiliates) shall not be released from Liability under this Section 3.3 or any JOA arising from a material breach of a financial or administrative obligation under this Agreement; provided that EP Energy’s (or any of its Affiliate’s) failure to timely pay Partner any Partner Monthly Revenues shall be deemed material.

Section 3.4 Joint Operating Agreements.

(a) Contemporaneously with the execution and delivery of this Agreement, the Parties have executed a joint operating agreement in the form attached hereto as Exhibit F (the “EP/Apollo JOA”) covering all Development Operations; provided, however, that, subject to Section 3.4(c), any Development Interests or Leases (i) in which any Party holds an interest as of the Execution Date and which are subject to an existing operating agreement involving a Third Party (whether the Third Party is a non-operating Working Interest owner or is operator), or (ii) which hereafter become subject to an operating agreement executed by the Parties and one or more Third Parties will, in addition to being subject to and governed by the EP/Apollo JOA be subject to and governed by such agreement (any agreement referred to in clause (i) or (ii), to the extent and only to the extent such agreement applies in respect of the Development Operations, is hereinafter referred to as a “Third Party JOA”).

(b) As between the Parties, each JOA insofar as it is applicable to the Development Interests associated with an Approved Drilling Program will be subject to the provisions of the Tax Partnership Agreement applicable to such Approved Drilling Program, unless and until the applicability of such provisions to the Development Interests subject to each such JOA terminates in accordance with the terms of such Tax Partnership Agreement.

(c) In the event of any conflict or inconsistency between the terms of this Agreement and the EP/Apollo JOA, then this Agreement will prevail to the extent of such

conflict. In the event any portion of the Development Interests is or becomes governed by a Third Party JOA, the terms of that Third Party JOA will control as between each applicable Third Party and the Parties to this Agreement; provided, however, that the EP/Apollo JOA and this Agreement will apply as between the Parties to the greatest extent practicable. If all of the Third Party Working Interests covered by a Third Party JOA are subsequently acquired by one or more of the Parties or their respective Affiliates, then such Third Party JOA will be superseded and replaced in its entirety by the EP/Apollo JOA (subject to the other terms of this Agreement).

(d) EP Energy will have the right from time to time to propose that the Parties enter into and amend joint operating agreements, unit agreements, pooling agreements and other similar agreements with Third Parties providing for all or any portion of Development Operations on such terms and conditions as EP Energy, acting as a reasonably prudent operator, determines appropriate. Partner will consider in good faith and promptly respond to such proposals from EP Energy.

(e) Notwithstanding anything herein to the contrary, but subject to the Reversion, in the event any Third Party to a JOA elects (or is deemed to have elected) to non-consent a Farmout Well or Elected Option Well (or any proposed operation related thereto), each Party shall acquire such Party’s proportionate share (based on each Party’s then-current Working Interest share) of any non-consent interest under the applicable JOA resulting from such Third Party non-consent election, and thereafter the Parties’ respective Working Interests in such Farmout Well or Elected Option Well shall be adjusted accordingly pursuant to the terms of such applicable JOA. EP Energy shall take all necessary action to make such election on Partner’s behalf pursuant to the terms of the applicable JOA.

Section 3.5 Rentals, Shut-in Well Payments and Minimum Royalties.

(a) EP Energy agrees to pay (i) all rentals, shut-in well payments, minimum royalties, additional bonus payments and any other payments necessary to renew, maintain or extend the Oil and Gas Interests included, or that may be included, in the Development Interests pursuant to the terms hereof (“Renewal Costs”) and (ii) unless and until Partner elects to take in-kind pursuant to Section 3.7(f), excluding the Renewal Costs covered by clause (i) above, all royalties, overriding royalties, production payments and other burdens on production required to be paid to lessors and holders of those burdens attributable to the Oil and Gas Interests included in the Development Interests, provided, however, that notwithstanding the terms of any JOA to the contrary, EP Energy shall make such payments in clause (ii) above on behalf of EP Energy and Partner and will invoice Partner with respect to Partner’s Working Interest share of such amounts in accordance with Section 5.2 and the EP/Apollo JOA or net Partner’s Working Interest share of such amounts from the Partner Monthly Revenue. Notwithstanding anything herein to the contrary, Partner shall not be liable for any Renewal Costs.

(b) EP Energy will not be liable to Partner for any act or omission pertaining to the performance of its obligations under this Section 3.5 or any loss resulting from such act or omission unless (in each case) such act or omission constitutes gross negligence or willful

misconduct by EP Energy or its Affiliates or any employee of EP Energy or any of its Affiliates.

(c) EP Energy will maintain the Leases as a reasonably prudent operator; provided that EP Energy may determine, in its reasonable discretion, not to renew, maintain or extend any of the Oil and Gas Interests included in the Development Interests, or that may be included in the Development Interests, pursuant to the terms hereof and, in such case, will provide Partner written notice of such decision not less than 30 days prior to the expiration of any such Oil and Gas Interest and afford Partner the opportunity to renew, maintain or extend, as applicable, such Oil and Gas Interest at Partner’s sole option, cost and expense. Should Partner so elect to renew, maintain, or extend such Oil and Gas Interest, as applicable, then, within 10 Business Days of the payment by Partner of any applicable amount required to do so, EP Energy shall Transfer to Partner the entirety of EP Energy’s and its Affiliates’ right, title and interest in and to such Oil and Gas Interest and thereafter such Oil and Gas Interest shall no longer be deemed subject to this Agreement or the EP/Apollo JOA.

Section 3.6 Insurance. Each Party will carry such applicable insurance required pursuant to the EP/Apollo JOA.

Section 3.7 Marketing and Gathering.

(a) The production of Entitlement from the Farmout Wells and Elected Option Wells (as applicable) will be subject to the terms and conditions set forth in the EP/Apollo JOA.

(b) Subject to Partner’s rights under Section 3.7(f), EP Energy will act as the marketer of EP Energy Production and Partner Production or will, at its discretion, appoint an Affiliate to do so (provided that EP Energy shall remain primarily liable for such Affiliate’s performance of the obligations set forth in this Section 3.7), which appointment may be revoked by EP Energy at any time (EP Energy or its Affiliate for the period of such appointment, the “Marketer”), and each of EP Energy (on behalf of itself and its Affiliates) and Partner (on behalf of itself and its Affiliates) designates Marketer as the marketer of EP Energy Production and Partner Production, as applicable.

(c) Subject to the terms of this Agreement (including Partner’s rights under Section 3.7(f) and Partner’s rights, if any, following a breach by EP Energy of Section 3.10) and any fees chargeable under the EP/Apollo JOA, Marketer will have exclusive authority to market and sell EP Energy Production and Partner Production and to enter into sales, transportation, gathering, storage, compression, treatment, processing and any other marketing related agreements, including such agreements with Oil and Gas Interests dedications, term and volume obligations and monetary commitments, on behalf of EP Energy (and its Affiliates) with respect to EP Energy Production and Partner (and its Affiliates) with respect to Partner Production (each such transaction, a “Marketing Transaction”); provided that any Marketing Transaction, (i) with respect to Partner Production, (ii) entered into on or after the Execution Date, and (iii) (A) that cannot be

terminated with 90 days’ prior written notice (including any Marketing Transaction that requires the dedication of any portion of Partner Production, but excluding any amendment to a contract of an existing Marketing Transaction that does not (1) obligate Partner to any additional volume commitment, (2) modify the price therein or (3) extend the term of such existing contract) or (B) that requires Partner to provide credit support, will require the prior written consent of Partner, which consent may not be unreasonably withheld, delayed or denied; provided, further, that if Partner fails to respond in writing within 10 Business Days of its receipt of EP Energy’s request for consent (which will be accompanied by such information necessary for Partner to approve such Marketing Transaction), Partner shall be deemed to have consented to such Marketing Transaction. All EP Energy Production and Partner Production will be marketed on the same terms as each other (including Oil and Gas Interests dedications). Marketer shall (x) use commercially reasonable efforts to sell Partner Production for the best available price at the time of entering into the Marketing Transaction, and (y) cause the weighted average price paid to Partner for Partner Production from any Farmout Well or Elected Option Well, as applicable, not to be less than the weighted average price paid to EP Energy (or its Affiliates) for the EP Energy Production from such Farmout Well or Elected Option Well, as applicable, during the same time period.

(d) Subject to Partner’s rights under Section 3.7(f), Marketer will make all nominations that are required under the terms of any Marketing Transaction entered into pursuant to Section 3.7(c). As requested by Marketer from time to time, each of EP Energy and Partner will reasonably cooperate and coordinate with Marketer in order to permit Marketer to perform under the terms of each Marketing Transaction with respect to EP Energy Production and Partner Production, as applicable.

(e) Title to the Partner Production will remain in Partner until such time as title to such Partner Production is required to be transferred to the buyer under the terms of the applicable Marketing Transaction. Except for the terms of each Marketing Transaction entered into pursuant to Section 3.7(c), Marketer will not have the right under this Agreement to encumber any Partner Production in any manner.

(f) With respect to any Well Group or Elected Option Well Group, at any time from and after the Completion of the last Farmout Well or Elected Option Well in such Well Group or Elected Option Well Group, subject to the terms and conditions of the then-existing Marketing Transactions, Partner will have the right at any time (and for a period of at least 12 months unless EP Energy otherwise agrees) to take-in-kind all of the Partner Production from such Well Group (or Elected Option Well Group), and separately market such Hydrocarbons for its own account. Partner’s take-in-kind election with respect to each Well Group and any Elected Option Well Group will be effective as of the time set forth in such written notice, which shall not be less than 30 days after the date of such written notice. At the effective time of such written notice, Marketer’s obligation with respect to the Partner Production for such Well Group or Elected Option Well Group in this Section 3.7 and EP Energy’s obligation with respect to the Partner Production for such Well Group in Section 3.5(b) shall terminate and shall be of no further force and effect for so long as Partner has elected to take the Partner Production in-kind. Notwithstanding the foregoing, (i) any

election by Partner to take its proportionate share of Hydrocarbons produced from the Wells in such Well Group or Elected Option Well Group, as applicable, in-kind shall be subject to the terms of any then-existing dedications, sales commitments, service commitments or Third Party marketing agreements and subject to Partner entering into an oil balancing agreement with Marketer in form and substance reasonably acceptable to Partner and Marketer; (ii) to the extent reasonably practicable, within 15 days after the last day of a Calendar Month, Partner shall promptly report to EP Energy the volume of the in-kind Partner Production sold during such Calendar Month, the respective price received for each of such sales and any other related information as reasonably requested by EP Energy; and (iii) Partner will not be charged a fee to access and utilize the Offsite Infrastructure existing as of such time and necessary to bring Partner Production to first sale (other than the fee charged to Partner under the EP/Apollo JOA). In the event that Partner so elects to take in-kind, Partner will bear and pay for any cost and expense related to any additional equipment and facilities to the extent (and only to the extent) required to allow Partner to take the Partner Production in-kind and such cost and expense will be included in the calculation of the IRR. In the event that Partner so elects to take in kind, Partner shall be solely responsible for paying (x) all royalties, overriding royalties, production payments and other burdens required to be paid to lessors and holders of those burdens and EP Energy shall provide Partner with all information related to such royalties and other burdens to enable such payment by Partner to such lessors and holders of those burdens and (y) all severance and other production Taxes, in each case of clause (x) and (y), attributable to the in-kind Partner Production for such Well Group. Notwithstanding the foregoing, in the event of a permitted Transfer by Partner of all or any portion of the Conveyed Interests to a Third Party in accordance with Article VIII, such Third Party shall not be bound by any time limitation set forth in the first sentence of this Section 3.7(f) with respect to any election to take in-kind all of its Entitlement from any particular Well Group.

(g) Each of EP Energy and Partner will be charged its Working Interest share of any applicable fees charged by a Third Party for all gathering and processing services provided by such Third Party service provider designated by EP Energy attributable to the Parties’ interests within the Development Area Boxes and any applicable fees chargeable under the EP/Apollo JOA for all gathering and processing services provided by Marketer.

(h) If the Parties agree to effect an election-out (as defined in, and in accordance with, the applicable Tax Partnership Agreement) with respect to a Well Group, then from and after such time the Parties agree that: (i) the provisions of this Section 3.7 (other than Section 3.7(f) and this Section 3.7(h)) shall cease to apply, (ii) Partner shall have the right to take in-kind and separately dispose of the Partner Production from such Well Group or Elected Option Well Group, as applicable, (iii) if Partner fails to make the arrangements necessary to take in-kind or separately dispose of the Partner Production from such Well Group or Elected Option Well Group, as applicable, EP Energy shall have the right, subject to the revocation at will by Partner upon at least 10 days’ written notice, but not the obligation, to purchase such production or sell it to others at any time and from time to time, for the account of Partner, provided that any such purchase or sale shall be only for such reasonable periods of time as are consistent with the minimum needs of the industry under the particular

circumstances, but in no event for a period in excess of one year; provided, further, that the effective date of any such revocation by Partner may be deferred at EP Energy’s election for a reasonable period of time if EP Energy has committed such production to a purchase contract having a term extending beyond such 10-day period, and (iv) to avoid an unintended impairment of the election-out, the Parties will (A) avoid any operational changes that would terminate the qualification for the election-out status, (B) monitor the continuing qualification for the election-out status and will notify the other Party if, in such Party’s opinion, a change in operations will jeopardize the election-out, and (C) use the cumulative gas balancing method in accordance with Treas. Reg. §1.761-2(d)(2) in connection with any gas imbalance.

Section 3.8 Contracts; Use of Affiliates.

(a) Subject to Section 3.8(b), EP Energy may enter into procurement contracts and agreements on customary and competitive terms and conditions in connection with any Development Operations conducted by or at the direction of EP Energy in which both Parties participate.

(b) Subject to Section 3.8(c), EP Energy may contract with its Affiliates to provide services, materials, sales or purchases in connection with Development Operations. All services performed, materials supplied or transactions by or with any such Affiliates will be performed or supplied pursuant to written agreements and in accordance with customs and standards prevailing in the industry and at competitive rates and terms (no less favorable than the customary, prevailing rates and terms when each such pertinent agreement was made); provided that any contracts executed or services provided pursuant to this Section 3.8(b) shall be on no less favorable terms than the terms applicable to EP Energy’s Entitlement or any other production from any Well in which EP Energy has an interest. EP Energy shall provide to Partner a copy of all such contracts entered into with such Affiliate promptly after execution thereof but, in any event, not less than 7 Business Days after execution.

(c) EP Energy shall not enter into any contract or group of substantially related contracts pursuant to Section 3.8(b) that could reasonably require aggregate expenditures in excess of $100,000 in any Calendar Year period without the prior written consent of Partner, which consent may be withheld in Partner’s sole discretion; provided that contracts with Affiliates of EP Energy where such Affiliates only pass through prices, costs, transport charges, other charges and revenues from contracts with Third Parties shall not be considered contracts with Affiliates of EP Energy for purposes of this Section 3.8(c).

Section 3.9 Force Majeure.

(a) If a Party is rendered unable, wholly or in part, by reason of a Force Majeure Event to perform its obligations under this Agreement, other than obligations to make payments when due hereunder, then such Party’s obligations will be suspended to the extent affected by the Force Majeure Event. Any Party claiming any Force Majeure Event shall use commercially reasonable efforts to overcome such Force Majeure Event as soon as

practicable and will provide prompt written notice thereof to the other Party (such notice shall be provided as soon as practicable and in no event later than five Business Days after the occurrence of a Force Majeure Event) including full particulars of such Force Majeure Event and, to the extent practicable, its plans to overcome such Force Majeure Event, and will keep the other Party fully advised of its efforts to overcome such Force Majeure Event; provided that the failure of any Party to give notice of a Force Majeure Event as described in this Section 3.9 will not affect its rights under this Section 3.9 except to the extent such failure materially and adversely affects the other Party.

(b) Should any Force Majeure Event render a Party unable to perform its obligations under this Agreement pursuant to the then-current Development Plan for a consecutive period of 120 days or more (or 180 days in any 365 day period, whether or not consecutive), then the Party (if any) whose performance under this Agreement is not affected by such Force Majeure Event may withdraw its approval for the remaining Development Operations in which EP Energy has not issued any billing statement, invoice or advance billing request with respect thereto and for which no Well has been spudded nor any site preparation or rig mobilization has begun by providing written notice to the other Party (and the applicable Approved Drilling Program shall be deemed modified by the removal of such Development Operations).

Section 3.10 Offsite Infrastructure. EP Energy will be responsible for the Offsite Infrastructure Costs and any Offsite Infrastructure will be owned solely by EP Energy. EP Energy shall construct and bring online all Offsite Infrastructure reasonably necessary to bring production from the Farmout Wells and Elected Option Wells to first sale in accordance with the timing set forth in an Approved Drilling Program.

Section 3.11 Management Services.

(a) The Parties hereby agree that in addition to those services EP Energy provides in its capacity as the operator and pursuant to the EP/Apollo JOA, EP Energy will provide or cause to be provided the management and administrative services described on Exhibit K to Partner with respect to the Conveyed Interests (the “Services”).

(b) Independent Contractor.

(i) EP Energy is, and will perform the Services as, an independent contractor of Partner.

(ii) EP Energy will determine in its sole discretion the number of employees, the selection of employees, the hours of work and the compensation to be paid to all employees used in performing the Services. Without limiting the preceding sentence, EP Energy will have the right to use professional and supervisory personnel, including engineers, technicians, accountants, outside legal counsel or other specialists in performing the Services as it deems advisable in its reasonable judgment. In addition, EP Energy will have the right to subcontract some or all of the Services to subcontractors of its choosing and reasonably believed

by it to be competent; provided, that (i) any failure by the subcontractors to perform any obligation under this Section 3.11 will not relieve EP Energy of its obligations under this Section 3.11; (ii) EP Energy agrees that it will not waive any obligation of the subcontractors under the subcontract agreements and will pursue all remedies available to it under the subcontract agreements, (iii) the subcontractor will not be authorized to perform any services for Partner on behalf of EP Energy that EP Energy is not authorized to perform under this Agreement and (iv) EP Energy shall use commercially reasonable efforts to ensure that there are no unsatisfied claims for labor, materials, equipment or supplies in connection with the Services except for those that are the subject of a bona fide dispute and which are being diligently contested.

(c) Settlement of Claims and Lawsuits. To the extent EP Energy receives notice from any Third Party of any material claims or suits that arise out of or relate to the Services, EP Energy will promptly notify Partner and the following will apply with respect to Partner’s Conveyed Interests: (i) EP Energy will represent EP Energy and Partner (if Partner is a defendant in the claim or suit) and defend or oppose each such claim or suit; provided, that, subject to clause (iv) below, Partner will pay for Partner’s then-current Working Interest share of legal fees and other costs and expenses related to such claim or suit to the extent relating to Partner’s interests in the applicable Farmout Wells and/or Elected Option Wells subject to Partner’s rights to indemnification under the terms of this Agreement; (ii) EP Energy may, in its sole discretion, compromise or settle any such claim or suit or any related series of claims or suits for an amount that does not exceed the equivalent of $100,000 U.S. dollars (exclusive of legal fees) to the extent such compromise or settlement fully resolves the claim or suit (or related series of claims or suits) and Partner will bear and pay for Partner’s then-current Working Interest share of the settlement or judgment to the extent relating to Partner’s interests in the applicable Farmout Wells and/or Elected Option Wells, subject to Partner’s rights to indemnification under the terms of this Agreement; (iii) EP Energy will obtain the written consent and direction of Partner for the conduct of claims or suits that EP Energy does not reasonably expect to be able to resolve for the above-stated amount or less and Partner will bear and pay for Partner’s then-current Working Interest share of the settlement or judgment thereof to the extent relating to Partner’s interests in the applicable Farmout Wells and/or Elected Option Wells, subject to Partner’s rights to indemnification under the terms of this Agreement; and (iv) Partner will have the right to be represented by its own counsel at its own expense in the settlement, compromise or defense of such claims or suits (and, in such event, such legal costs and expenses will not be included in the calculation of the IRR).

(d) Compensation. With respect to the Services provided by EP Energy hereunder, Partner will pay to EP Energy a monthly fee of $10,000 (the “Management Fee”); provided that Partner may, upon 30 days’ prior written notice, elect to terminate the Services provided by EP Energy hereunder and discontinue payment of the Management Fee, effective as of the first of the Calendar Month immediately after the expiration of such 30-day period.

(e) Billing, Payments. Amounts due to EP Energy under this Section 3.11 will be billed in arrears and payable in accordance with Section 5.2.

Section 3.12 Hedging.

(a) Each Party is responsible for conducting (for its own account) any hedging activities with respect to its share of production from the Development Operations. Partner may enter into any hedging contract affecting Partner’s Entitlement in its sole discretion; provided that the calculation of the IRR may only include settlement costs, gains or losses pursuant to a Hedge Contract that is approved by EP Energy in writing prior to the execution thereof (each such Hedge Contract, a “Permitted Hedge Contract”) and all other costs associated with, and gains and losses realized from, Partner’s hedging activities are excluded from the calculation of the IRR.

(b) Unless otherwise agreed in writing, all derivative activities, including any purchasing or repurchasing of Hydrocarbons, of EP Energy will be outside the scope of this Agreement (including the Services), and Partner will not benefit from, or be burdened or restricted by, any of EP Energy’s derivative activities.

(c) Except for settlement costs, gains or losses pursuant to the Permitted Hedge Contracts, no costs, gain or loss associated with any other derivative activities of Partner will be included in the calculation of the IRR. The Parties anticipate that, immediately prior to Reversion, Partner will terminate the portion of Permitted Hedge Contracts then outstanding necessary to reflect Partner’s reduced Working Interest following Reversion, except to the extent the Parties mutually agree to novate the applicable portion of any such Permitted Hedge Contracts to EP Energy upon Reversion. All proceeds received by Partner in connection with the settlement or novation of a Permitted Hedge Contract and costs paid by Partner in connection with the settlement or novation of a Permitted Hedge Contract shall be included in the calculation of the IRR.

(d) Prior to the Reversion of the applicable Well Group, Partner will report to EP Energy its settlement costs, gains and losses with respect to the applicable Permitted Hedge Contracts no later than the 30th day following the end of each Calendar Quarter.

Section 3.13 Third Party Rights.

(a) Within five Business Days after the Execution Date, EP Energy will send to (i) the holder of any Preferential Purchase Right or Consent pertaining to an applicable Oil and Gas Interest and (ii) all Third Parties to any Third Party JOA containing an applicable maintenance of uniform interest provision (each, a “Third Party Right”), an election notice, consent request, or waiver request, as appropriate regarding the Transfer of the subject Conveyed Interest to Partner, as well as the Reversion of such Conveyed Interest. EP Energy will use its commercially reasonable efforts to promptly obtain a consent or waiver of such Third Party Right; provided that EP Energy will not be required to pay the holder of any Preferential Purchase Right or Consent any money in order to obtain such waiver or consent. EP Energy shall provide copies of (A) all applicable written notices and requests sent to

holders of Third Party Rights and (B) all written communications received from such holders within five Business Days of sending such notice or requests or receiving such communications (as applicable).

(b) Prior to submitting an AFE to Partner, EP Energy must have obtained an express waiver or consent related to all Third Party Rights burdening the Well described in such AFE or such AFE must disclose the Third Party Rights for which EP Energy was unable to obtain consents or waivers thereof. To the extent any AFE includes such a disclosure or Partner provides written notice to EP Energy that it believes in good faith that an unobtained Third Party Right affects the Well described in such AFE and EP Energy does not obtain such consents or waivers within 15 days of Partner’s receipt of such AFE, then Partner will be deemed to have elected to withdraw its consent related to such Well unless Partner delivers written notice to EP Energy of its election to participate in such Well subject to the unobtained Third Party Right within 15 days of its receipt of such AFE. In the event of such withdrawal, the relevant Approved Drilling Program will be deemed to be amended to remove the affected Well. In the event Partner delivers written notice to EP Energy of its election to participate in such Well subject to the unobtained Third Party Right pursuant to this Section 3.13(b), Partner shall RELEASE, DEFEND, PROTECT, INDEMNIFY and HOLD HARMLESS the EP Energy Indemnified Parties from and against any Liability that arises due to the failure to obtain any such unobtained Third Party Right and any amounts attributable to such Liability shall not be included in the calculation of the IRR.

Section 3.14 Drainage. Unless otherwise expressly agreed in an Approved Drilling Program, neither EP Energy nor an Affiliate shall place the Effective Lateral portion of any wellbore closer than 770’ for Wells in the same Bench and 1,540’ for Wells in the same Parasequence, in each case, to an existing horizontal Effective Lateral of a Farmout Well or Elected Option Well or any proposed future horizontal Effective Lateral for any Well Location; provided that following Reversion of a Well Group, EP Energy may propose tighter well spacing by delivering to Partner reasonable supporting documentation contemporaneously with delivery of the applicable AFE demonstrating that such spacing (i) is not reasonably likely to drain a Farmout Well or Elected Option Well and (ii) will not cause a material reduction in the type curves for the affected Farmout Well(s) or Elected Option Well(s); provided, further, that in no event shall the Effective Lateral portion of any wellbore be drilled closer than 335’ for Wells in the same Bench and 770’ for Wells in the same Parasequence, in each case to an existing horizontal Effective Lateral of a Farmout Well or Elected Option Well or any proposed future horizontal Effective Lateral for any Well Location (unless otherwise agreed in an Approved Drilling Program). If EP Energy proposes revisions to the approved well spacing in accordance with the preceding sentence, Partner will have the right to consent or not to consent to such proposal in Partner’s sole discretion. EP Energy shall be deemed to be in compliance with the spacing requirements set forth herein if the actual spacing of the Effective Lateral portion of the wellbores equals 90% or more of the applicable spacing requirements set forth herein unless such deviation from the applicable spacing requirements is a result of, or relates to, an intentional or willful act by EP Energy that is not approved by Partner in accordance with the preceding sentence. EP Energy and its Affiliates shall not propose (or request that a Third Party propose) any well under a Third Party JOA that would violate the spacing requirements set forth in the preceding sentence(s); provided, however, that this Section 3.14 will not restrict

operations by Third Parties to the extent such operations are not proposed by EP Energy or an Affiliate and EP Energy or any of its Affiliates did not request any Third Party to propose such operation.

Section 3.15 Commingling of Hydrocarbons. The Parties acknowledge and agree that each well pad for Farmout Wells and Elected Option Wells shall contain one or more allocation meters such that the Parties are able to accurately determine (subject to minor measurement errors that occur in the ordinary course of business) the quantity of Hydrocarbons produced from each such well pad. Such Hydrocarbons shall not be commingled with other Hydrocarbons produced by EP Energy from wells other than Farmout Wells or Elected Option Wells until such Hydrocarbons have moved past the applicable wellhead allocation meter. EP Energy shall not use any well pad on which any Farmout Well or Elected Option Well is located for any other wells other than Farmout Wells and Elected Option Wells.

Section 3.16 University Lands Royalty Matters. The Parties acknowledge and agree that the Farmout Wells and Elected Option Wells (if applicable) will be subject to the CDDU, including the Fifth Amendment to the CDDU. Without limiting the foregoing, (a) the Conveyed Interests shall be subject to any Variable Royalty (as defined in the Fifth Amendment to the CDDU) or Fixed Royalty (as defined in the Fifth Amendment to the CDDU), as applicable, pursuant to the CDDU, attributable to the applicable Farmout Well or Elected Option Well, (b) Partner shall bear the Initial Partner Working Interest Share or Residual Partner Working Interest Share, as applicable, of any True-Up Payment (as defined in the Fifth Amendment to the CDDU) attributable to the applicable Farmout Well or Elected Option Well, and (c) if Partner elects to reject the Proposed Second Tranche Drilling Program, solely with respect to the Calendar Year in which such election was made, Partner shall bear the Initial Partner Working Interest Share of any Non-Performance Fee (as defined in the Fifth Amendment to the CDDU) for such Calendar Year due pursuant to the Fifth Amendment to the CDDU. Except for Elected Option Wells, any Well Opt-Out Election (as defined in the Fifth Amendment to the CDDU) by EP Energy with respect to any of the Farmout Wells pursuant to the CDDU (which Well Opt-Out Election shall be described in the applicable Option Well Notice and shall set forth whether such Well Opt-Out Election applies to any Elected Option Well in such Option Well Notice) shall be made only with Partner’s prior written consent.

Article IV
APPROVED DRILLING PROGRAMS; LIMITATION ON WELL COSTS

Section 4.1 First Tranche Drilling Program.

(a) Attached as Exhibit D is the work program and budget for the First Tranche (as such program may be amended or modified (or deemed amended or modified) pursuant to this Agreement, the “First Tranche Drilling Program”). Subject to Section 3.9, Section 4.2(f) and Section 4.2(g), EP Energy will implement the First Tranche Drilling Program in accordance with the schedule set forth in Exhibit D.

Section 4.2 Approved Drilling Programs.

(a) The First Tranche Drilling Program is deemed to be an Approved Drilling Program.

(b) No later than 60 days prior to Completion of the last Farmout Well of the First Tranche Drilling Program, EP Energy will prepare and submit to Partner, a proposed work program and budget for the Second Tranche meeting the Qualifying Plan Criteria and containing (i) at least the Required Plan Terms and (ii) any applicable amendment to the Development Area Boxes for the Second Tranche as long as the Development Area Boxes remain wholly contained within EP Energy’s leasehold position in the Midland Basin existing as of the Execution Date (the “Proposed Second Tranche Drilling Program”); provided that if Partner is a Defaulting Party, EP Energy shall have the right, but not the obligation, to submit the Proposed Second Tranche Drilling Program. EP Energy will have the exclusive right to propose the Proposed Second Tranche Drilling Program.

(c) Within 60 days of Partner’s receipt of the Proposed Second Tranche Drilling Program (the “Second Tranche Approval Deadline”), Partner must approve or reject in writing the Proposed Second Tranche Drilling Program. Prior to the Second Tranche Approval Deadline, EP Energy may submit revisions to such Proposed Second Tranche Drilling Program; provided that if EP Energy submits any revisions within 15 days of the Second Tranche Approval Deadline, the Second Tranche Approval Deadline shall be extended such that Partner has an additional 30 days to approve or reject the revised Proposed Second Tranche Drilling Program. Partner may approve the Proposed Second Tranche Drilling Program and, prior to or simultaneously with such approval, elect to exclude (in its sole discretion) certain Farmout Wells included in such Proposed Second Tranche Drilling Program if Partner reasonably believes that (i) any such Farmout Wells are subject to an Environmental Condition that would cause a reasonably prudent operator not to drill such Wells in its ordinary course of business or (ii) such Farmout Wells are subject to an uncured title issue that would cause a reasonably prudent operator not to drill such Farmout Wells in its ordinary course of business, and, in either case, such exclusion will not be considered a revision to the Proposed Second Tranche Drilling Program subject to rejection by EP Energy. If Partner elects to exclude certain Farmout Wells from the Proposed Second Tranche Drilling Program prior to or simultaneously with its approval thereof pursuant to the preceding sentence, then, subject to the proviso of this sentence, any such Well Location excluded from the Proposed Second Tranche Drilling Program will be excluded from the terms of this Agreement and deemed to be deleted from Exhibit A; provided that EP Energy shall have the right, but not the obligation, to attempt (within the 180-day period following such election to exclude such Farmout Wells), at EP Energy’s sole cost, to cure, remediate or remove any such Environmental Condition or title issue to Partner’s reasonable satisfaction and upon the completion of such cure, remediation or removal to Partner’s reasonable satisfaction, any such Farmout Well shall be automatically included in the Second Tranche Drilling Program, if any, and the Well Location for such Farmout Well shall be deemed to be included in Exhibit A without any further action by the Parties. If Partner proposes any revisions to the Proposed Second Tranche Drilling Program prior to approval, then EP Energy will consider such proposed revisions in good faith and discuss the proposed revisions with Partner, but EP Energy shall be under no obligation to accept any revisions

proposed by Partner (other than any election by Partner to exclude any Farmout Well from the Proposed Second Tranche Drilling Program pursuant to the first sentence of this Section 4.2(c)). In the event that Partner fails to notify EP Energy in writing of its approval or rejection prior to the Second Tranche Approval Deadline, Partner will conclusively be deemed to have rejected the Proposed Second Tranche Drilling Program. If Partner approves the Proposed Second Tranche Drilling Program in accordance with this Section 4.2(c), then such program, as may be amended or modified (or deemed amended or modified) pursuant to this Agreement, shall be referred to herein as the “Second Tranche Drilling Program”.

(d) The inclusion of an operation within the scope of an Approved Drilling Program will (unless and until such operation is removed from such Approved Drilling Program pursuant to an amendment thereof, including under Section 4.2(g)), subject to Section 2.1(d), Section 2.4, Section 3.9(b), Section 3.13 and Section 4.3, (i) bind each Party to participate in such operation; and (ii) authorize EP Energy to conduct such operation for the account of EP Energy and Partner under the relevant JOA (provided that, (A) to the extent any Third Parties are party to such JOA, EP Energy will propose such operation to such Third Parties in accordance with the terms of such JOA, and (B) with respect to any Development Operation pertaining to a Farmout Well or Elected Option Well contemplated in the applicable Approved Drilling Program, EP Energy will submit copies of the applicable AFE to Partner at least 15 days prior to the commencement of drilling operations for such Farmout Well).

(e) If Partner does not approve, or is deemed to have rejected, the Proposed Second Tranche Drilling Program by the deadline set forth in Section 4.2(c), then Partner will not be entitled to earn any interest in any Well Locations that have not been included in the First Tranche Drilling Program and this Agreement will terminate in accordance with Section 10.1(b).

(f) In the event of Partner’s withdrawal or deemed withdrawal from an Approved Drilling Program or any portion thereof (including pursuant to Section 2.1(d)), Partner (i) will not be entitled to earn any interest in any Well Locations included in such Approved Drilling Program that have not yet been spudded prior to the date of such withdrawal or deemed withdrawal, or for which site preparation or rig mobilization has not yet begun, (ii) will be deemed to have elected not to participate and to have nonconsented to all of the Development Operations proposed by EP Energy for any Well Locations included in such Approved Drilling Program that have not yet been spudded prior to the date of such withdrawal or deemed withdrawal, or for which site preparation or rig mobilization has not yet begun, (iii) will continue to be bound by such Approved Drilling Program with respect to any Well spudded prior to the date of such withdrawal or deemed withdrawal, or site preparation or rig mobilization has already begun, and (iv) will not have access to the information and data generated in connection with the Development Operations for which Partner is not entitled to earn an interest.

(g) Quarterly Meetings.

(i) During the Availability Period, EP Energy will host quarterly meetings with Partner to review historical drilling, Completion and performance results, as well as proposed field development and exploration plans and land management activities (each such meeting, a “Quarterly Meeting”). Each Quarterly Meeting shall occur within the first Calendar Month in each Calendar Quarter unless otherwise agreed to by the Parties. Following the Availability Period, in lieu of Quarterly Meetings (which will no longer be held), upon Partner’s written request, EP Energy will host meetings with Partner to review current field operations, budget matters and land management activities; provided that Partner may not request any such meeting more than two times per Calendar Year. Partner may request, upon 15 days’ prior written notice, specific agenda topics to be covered during a Quarterly Meeting or semi-annual meeting, including any technical or planning issues related to the Development Operations or Development Interests. At least 5 Business Days prior to each Quarterly Meeting and any subsequent annual or semi-annual meeting, EP Energy shall provide to Partner an agenda of the matters to be discussed (and copies of any documents or materials to be discussed) at such meeting.

(ii) At a Quarterly Meeting (commencing on the Quarterly Meeting held in the first Calendar Quarter of 2017), EP Energy may propose amendments or modifications to the applicable Approved Drilling Program with respect to Wells of which EP Energy has not issued any billing statement, invoice or advance billing request to the extent that (A) the applicable Approved Drilling Program no longer accurately reflects the market conditions and (B) increased Third Party service costs and materials have caused the expected aggregate costs for such Wells to be equal to or more than 101.5% of the aggregate estimated costs for such Wells in the applicable Approved Drilling Program; provided that EP Energy may not propose amendments to the applicable Approved Drilling Program on account of any service delays or Completion or Well performance issues that cause an increase in service costs. Any proposal made by EP Energy hereunder shall be made in good faith, and shall include (to the extent reasonably practicable) any such information or documentation that may be reasonably requested by Partner, including any Third Party rig rate or frac rate proposals received by EP Energy and such other information that will assist Partner in assessing the revised economic potential of the applicable Wells. If Partner reasonably believes that any such proposal made by EP Energy may materially impact the type curve for any applicable Well, EP Energy shall also provide revised type-curve economic support for such Wells. Partner will have 15 Business Days following a Quarterly Meeting to review such proposals and provide its written approval or rejection thereof to EP Energy. If Partner approves such proposal, then the applicable Approved Drilling Program shall be automatically amended, including for the purpose of Section 4.3. If Partner provides written notice to EP Energy within 10 Business Days following such Quarterly Meeting that it does not approve any of such proposals, then the Parties will meet within five Business Days thereafter in an effort to resolve such disputed matters. If Partner has not approved such proposals (or a mutually agreed modified version thereof) within 15 Business Days after such Quarterly Meeting, then all

(but not less than all) of such future Wells included in EP Energy’s proposal may, at EP Energy’s election (in its sole discretion), be removed from the applicable Approved Drilling Program.

(iii) At a Quarterly Meeting (commencing on the Quarterly Meeting held in the first Calendar Quarter of 2017), EP Energy may propose amendments or modifications to the applicable Approved Drilling Program with respect to Wells of which EP Energy has not issued any billing statement, invoice or advance billing request to the extent that changes in Completion technology or design cause the expected aggregate costs for such Wells to be in excess in any material respect of the aggregate estimated costs for such Wells in the applicable Approved Drilling Program. Any proposal made by EP Energy hereunder shall be made in good faith, and shall include (to the extent reasonably practicable) any such information or documentation that may be reasonably requested by Partner. If Partner reasonably believes that any such proposal made by EP Energy may materially impact the type curve or economic potential for any applicable Well, EP Energy shall also provide revised type-curve economic support for such Wells. Partner will have 15 Business Days following a Quarterly Meeting to review such proposals and provide its written approval or rejection thereof to EP Energy. If Partner approves such proposal, then the applicable Approved Drilling Program shall be automatically amended, including for the purposes of Section 4.3. If Partner provides written notice to EP Energy within 10 Business Days following such Quarterly Meeting that it does not approve any of such proposals, then the Parties will meet within five Business Days thereafter in an effort to resolve such disputed matters. If Partner has not approved such proposals (or a mutually agreed modified version thereof) within 15 Business Days after such Quarterly Meeting, then, subject to Section 4.3, EP Energy shall Complete such future Wells included in EP Energy’s proposal in accordance with the Completion technology or design included in the applicable Approved Drilling Program in effect immediately prior to such proposal by EP Energy.

(iv) Notwithstanding anything to the contrary herein, EP Energy may amend or modify the applicable Approved Drilling Program (including for the purposes of Section 4.3) with respect to Wells for which EP Energy has not issued any billing statement, invoice or advance billing request to Partner to provide for (A) (I) any changes in the order of Wells to be drilled or (II) changes to the coordinates of any future Well Locations that do not require a new drilling permit from the applicable Governmental Authority, or (B) with Partner’s prior written consent, changes to the coordinates of any future Well Locations that would require a new drilling permit from the applicable Governmental Authority; provided, however, that EP Energy may change the coordinates for up to a maximum of 15 future Well Locations in any Approved Drilling Program, without Partner’s prior consent, so long as the new coordinates for each such Well Location are located in any of the Development Area Boxes; provided, further, that any future Well Location that (x) the change of the coordinates thereof has been consented to in writing by Partner or (y) the change of the coordinates thereof was made pursuant

to clause (A)(II) above will not count towards the 15 future Well Locations as set forth in the immediately preceding proviso.

(v) If, following the initiation of the then-current Approved Drilling Program and before the end of the second Calendar Quarter of such Approved Drilling Program, a Low Price Trigger Event occurred and there was no subsequent High Price Trigger Event after any such Low Price Trigger Event, then either Party may suspend its approval for the remaining Development Operations of such Approved Drilling Program for which EP Energy has not issued any billing statement, invoice or advance billing request to Partner and for which no Well has been spudded nor any site preparation or rig mobilization has begun by providing written notice to the other Party within 10 days following the end of such second Calendar Quarter. If either Party suspends its approval for the remaining Development Operations of an Approved Drilling Program in accordance with this Section 4.2(g)(v), EP Energy will not be obligated to carry out any of such Development Operations during such suspension. If Partner suspends its approval for the remaining Development Operations of an Approved Drilling Program in accordance with this Section 4.2(g)(v), EP Energy will be entitled to conduct any such Development Operations as sole risk operations during such suspension and the provisions of Section 4.2(f) shall apply to such Development Operations. Any sole risk operations conducted by EP Energy pursuant to the immediately preceding sentence shall be excluded from the applicable Approved Drilling Program (and the applicable Approved Drilling Program shall be deemed modified by the removal of such Development Operations) and the terms and conditions of this Agreement, and if such Approved Drilling Program is subsequently resumed in accordance with this Section 4.2(g)(v), then EP Energy shall propose substitute Wells to be included in such Approved Drilling Program with Partner’s prior written consent (which consent shall not be unreasonably withheld, delayed or denied). In the event that EP Energy suspends its approval for the remaining Development Operations of an Approved Drilling Program in accordance with this Section 4.2(g)(v), Partner will not be entitled to conduct such Development Operations during such suspension. In the event that a High Price Trigger Event following a suspension pursuant to this Section 4.2(g)(v) occurs on or before the 12 month anniversary of the date of the Low Price Trigger Event, such suspension shall automatically terminate and the applicable Approved Drilling Program shall resume, and the calendar schedule for such Approved Drilling Program shall be adjusted by EP Energy to account for the delay in work caused by such suspension. In the event that a High Price Trigger Event does not occur on or before the 12 month anniversary date of the Low Price Trigger Event, then either Party shall have the option to withdraw its approval for all remaining Development Operations in which EP Energy has not issued any billing statement, invoice or advance billing request with respect thereto and for which no Well has been spudded nor any site preparation or rig mobilization has begun by providing written notice to the other Party (and the applicable Approved Drilling Program shall be deemed modified by the removal of such Development Operations).

Section 4.3 Limitation on Well Costs and Carried Costs.

(a) Subject to any amendment approved by the Parties pursuant to Section 4.2(g) and the last sentence of this Section 4.3(a), with respect to each Farmout Well drilled pursuant to an Approved Drilling Program, Partner’s aggregate payment obligation of (i) its share of Qualified Costs and (ii) the Carried Costs of such Farmout Well will not exceed an aggregate amount equal to 107.5% of (i) its share of the aggregate amount of Qualified Costs (including the Carried Costs) set forth in the applicable Approved Drilling Program for (A) such Farmout Well and (B) any previously drilled and/or Completed Farmout Wells under such Approved Drilling Program minus (ii) the aggregate amount of all Qualified Costs (including Carried Costs) actually paid by Partner (whether pursuant to an invoice or netting by EP Energy) for all previously drilled and/or Completed Farmout Wells covered under such Approved Drilling Program (the “Partner Qualified Cost Cap”). EP Energy will bear and pay any Qualified Costs for such Farmout Well in excess of the Partner Qualified Cost Cap. In the event EP Energy bears any such excess Qualified Costs, EP Energy shall be permitted to recover such excess Qualified Costs by charging to Partner additional Qualified Costs (in addition to its share of Qualified Costs and the Carried Costs) (“Partner Qualified Cost Cap Make-Up Amount”) with respect to any subsequent Farmout Well in the same Approved Drilling Program to the extent the Qualified Costs for such subsequent Farmout Well are less than the Partner Qualified Cost Cap for such subsequent Farmout Well.

(b) Notwithstanding anything to the contrary in this Agreement, (i) EP Energy is expressly authorized to make expenditures and incur Liabilities for the joint account of the Parties when it reasonably determines that such expenditures or incurrences are necessary or advisable to prevent, respond to or remediate emergencies (to the extent such emergencies affect both Parties or relate to any Development Operation in which both Parties are participating), including well blowouts, fires, oil spills or any other similar event, which may imminently and materially endanger property, human safety or the environment, including wildlife, and only to the extent that prior notice to the Parties consistent with this Agreement is not reasonably possible, and (ii) EP Energy will, as soon as practicable, report to the Parties the nature of any such emergency which arises, the measures it intends to take or has taken in respect of such emergency and the estimated related expenditures, which, subject to Partner’s right (if any) to indemnity hereunder, will be borne by the Parties in accordance with their respective then-current Working Interest share as though set forth in the applicable Approved Drilling Program.

Section 4.4 Cost Reconciliation Account. Notwithstanding anything else to the contrary herein, on or after the date that is 10 days after the public announcement of the transaction contemplated by the Agreement, EP Energy shall issue a billing statement to Partner for the Initial Partner Working Interest Share of Well Costs and for applicable Carried Costs that have been incurred by and invoiced to EP Energy in connection with Development Operations prior to the Execution Date (such amount, collectively, the “Initial Well Cash Amount”). Partner shall pay the Initial Well Cash Amount in accordance with the procedures set forth in Section 5.2(c) into the Cost Reconciliation Account. Notwithstanding anything herein to the contrary, the Initial Well Cash

Amount (and any interest earned thereon) will be used solely to fund the Well Costs chargeable to EP Energy under this Agreement that are incurred following the Execution Date.

Section 4.5 Performance Obligations. Subject to the last sentence of Section 3.1(d), Section 3.9, Section 4.2(g)(ii), Section 4.2(g)(iii), Section 4.2(g)(iv), Section 4.2(g)(v), and Section 10.2 (if this Agreement is terminated pursuant to Section 10.1), unless permanently plugged and abandoned, EP Energy shall drill and Complete (including by bringing online) all Farmout Wells and Elected Option Wells (as applicable) provided in an Approved Drilling Program or an Option Well Notice (as applicable) in accordance with such Approved Drilling Program or Option Well Notice (as applicable) and on as close to the timing described in the applicable Approved Drilling Program or Option Well Notice as may be reasonably practicable.

Section 4.6 Additional Wells.

(a) During the Availability Period and subject to the last sentence of this Section 4.6(a), in the event EP Energy desires to drill any Well targeting any Bench (i) located within the Midland Basin, but outside the Development Area Boxes, that is not a Farmout Well and which EP Energy, in its sole discretion, intends to offer to Partner for its participation in accordance with this Section 4.6, or (ii) located within any Development Area Box that is not a Farmout Well (each such Well described in clause (i) or (ii), an “Additional Well”), then on or before 30 days prior to the spudding of such Additional Well, EP Energy shall provide Partner with written notice setting forth EP Energy’s proposal for the drilling of such Additional Well (an “Additional Well Notice”), which notice shall include (i) the applicable terms required for an Option Well Notice under Section 7.2 and (ii) the latitude and longitude of the Effective Lateral of any applicable Farmout Well where the latitude and longitude was not previously identified and could be closer than 770’ for Wells in the same Bench and 1,540’ for Wells in the same Parasequence. Partner will have 30 days following receipt of an Additional Well Notice within which to elect to participate in the Additional Well described in such Additional Well Notice on the same terms as a Farmout Well under this Agreement. If Partner fails to respond within such 30-day period, it will be deemed to have elected not to participate in such Additional Well; provided, however, if EP Energy fails to spud such Additional Well within 180 days following such 30-day period, then Partner shall not be deemed to have elected not to participate in such Additional Well and EP Energy shall be required to send a new Additional Well Notice should it decide to spud such Additional Well thereafter. For the avoidance of doubt, (A) until the Completion of the last Farmout Well included in the First Tranche Drilling Program, Partner shall have the option to participate in any Well drilled within the Development Area Boxes that are part of the First Tranche Drilling Program and (B) until the Completion of the last Farmout Well included in the Second Tranche Drilling Program, Partner shall have the option to participate in any Well drilled within the Development Area Boxes that are part of the Second Tranche Drilling Program, in each case, as provided in this Section 4.6.

(b) If Partner elects to participate in any Additional Well under this Section 4.6, then, except for the purpose of the last sentence of Section 4.6(a), such Additional Well shall be deemed a Farmout Well for all purposes hereunder and the First Tranche Drilling Program

or Second Tranche Drilling Program, whichever is being completed at the time of Partner’s election with respect to such Additional Well, shall be deemed amended to include such Additional Well and the terms set forth in the applicable Additional Well Notice with respect to such Additional Well.

Article V
CERTAIN PAYMENT OBLIGATIONS

Section 5.1 Well Costs; Carried Costs.

(a) Subject to Section 4.3 and Section 5.1(b), and without limitation of Partner’s right to indemnity hereunder, (i) with respect to any Farmout Well, Partner will pay or reimburse EP Energy, as applicable, for (A) Partner’s then-current Working Interest share (being the Initial Partner Working Interest Share prior to the Reversion with respect to such Well and the Residual Partner Working Interest Share after the Reversion with respect to such Well) of Well Costs attributable to such Farmout Well and (B) the Partner Qualified Cost Cap Make-Up Amount, if any, and (ii) with respect to any Elected Option Well, Partner will pay or reimburse EP Energy, as applicable, for the Residual Partner Working Interest Share of Well Costs attributable to such Elected Option Well. Such payment will be made in accordance with Section 5.2 and the EP/Apollo JOA.

(b) Subject to Section 4.3, in addition to the amounts payable under Section 5.1(a), for a period beginning on the Execution Date and ending upon the end of the Availability Period (the “Carry Period”), and notwithstanding the terms of any JOA to the contrary, Partner will pay, on behalf of EP Energy and its Affiliates, 20% of all Qualified Costs otherwise included within EP Energy’s Initial EP Energy Working Interest Share of Well Costs for Farmout Wells included in an Approved Drilling Program (all such Qualified Costs that Partner is obligated to pay, on behalf of EP Energy and its Affiliates, pursuant to this Section 5.1, the “Carried Costs”). For the avoidance of doubt, if the Development Interest in any Farmout Well is a 100% Working Interest (on an 8/8ths basis) and if there is no Partner Qualified Cost Cap Make-Up Amount, during the Carry Period, then, subject to Section 4.3, Partner would pay 60% of all Qualified Costs included in the Well Costs and attributable to the Development Interest for such Farmout Well and Partner’s obligation to pay Carried Costs for such Farmout Well would terminate when such Farmout Well was initially Completed, online and producing, subject only to the installing of a pumping unit (if any, as set forth in the applicable Approved Drilling Program) thereafter. Subject to Section 4.3, Partner will pay the Carried Costs in the same manner and at the same time it pays Partner’s Initial Partner Working Interest Share of Well Costs attributable for the Farmout Wells pursuant to Section 5.2(a); provided, that all such payments during the Carry Period will be deemed, first, to be a payment in respect of the Carried Costs due at such time and, second, and only to the extent that the portion of the Carried Costs that is due at such time is paid in full, to be a payment in respect of Partner’s Initial Partner Working Interest Share of Well Costs. Any reimbursement for any Carried Costs paid by Partner will be deducted from the calculation of the Carried Costs promptly after Partner’s receipt of such reimbursement. Any reimbursed amounts retained by EP Energy will be used towards future payment

obligations of Partner for Carried Costs and Partner’s Initial Partner Working Interest Share of Well Costs.

(c) EP Energy shall pay (i) with respect to any Farmout Well, (A) prior to Reversion with respect to such Farmout Well, the Initial EP Energy Working Interest Share of Well Costs (to the extent not constituting Carried Costs or the Partner Qualified Cost Cap Make-Up Amount) attributable to such Farmout Well and (B) on and after Reversion with respect to such Farmout Well, the Residual EP Energy Working Interest Share of Well Costs attributable to such Farmout Well, (ii) if applicable, Qualified Costs in excess of the Partner Qualified Cost Cap as described in Section 4.3 attributable to the Farmout Wells and (iii) with respect to any Elected Option Well, the Residual EP Energy Working Interest Share of Well Costs attributable to such Elected Option Well.

(d) Each Party shall be responsible for its respective Working Interest share of Lease Operating Expenses.

Section 5.2 Payment Procedures.

(a) Except with respect to Partner Production attributable to a Well Group or an Elected Option Well Group for which Partner has elected to take in-kind pursuant to Section 3.7(f), from and after the date hereof, EP Energy will, on behalf of Partner, receive and collect all revenues and proceeds attributable to the Partner Production to the extent marketed by Marketer (such revenues and proceeds actually received in any Calendar Month, the “Partner Monthly Revenue”) and make disbursements of such Partner Monthly Revenue as follows:

(i) first, to the applicable taxing authority, any Asset Taxes calculated by reference to Partner’s Working Interest with respect to the Wells in the then-effective Approved Drilling Programs;

(ii) second, to the owner of any Burden with respect to the Wells in the then-effective Approved Drilling Programs, the amounts owing in respect of Partner’s and its Affiliates’ Working Interest in such Well Groups;

(iii) third, to the payees thereof or to EP Energy, subject to Section 4.3 (to the extent applicable), Partner’s and its Affiliates’ share of the amounts to be paid to Third Parties or paid or reimbursed to EP Energy for the conduct of the Development Operations and other operations under this Agreement or the Associated Agreements, in each case, only to the extent such amounts are chargeable under this Agreement or the applicable JOA and for which Partner is responsible under this Agreement or the applicable JOA; and

(iv) fourth, to Partner, any residual amount after making the payments described above.

For the avoidance of doubt, the Parties acknowledge and agree that, in addition to being subject to this Agreement, the Farmout Wells or Elected Option Wells may be subject to one or more JOAs (including the EP/Apollo JOA). The Parties further acknowledge and agree that EP Energy shall have the right to aggregate and offset (1) amounts owed in respect of any Farmout Wells or Elected Option Wells by EP Energy to Partner or any of its Affiliates under this Agreement and any amounts owed in respect of any Farmout Wells or Elected Option Wells by EP Energy to Partner or its Affiliates under any and all such JOAs (whether or not EP Energy is acting as “operator” under such JOA(s)), on the one hand, and (2) amounts owed in respect of any Farmout Wells or Elected Option Wells by Partner or its Affiliates to EP Energy under this Agreement and amounts owed in respect of any Farmout Wells or Elected Option Wells to EP Energy by Partner or its Affiliates to EP Energy (or to the joint account) under any and all such JOAs (whether or not EP Energy is acting as “operator” under such JOA(s)), on the other hand. Without limiting the generality of the foregoing or any lien rights in favor of EP Energy under any applicable JOA, with respect to Partner and its Affiliates, EP Energy is authorized to deduct any amount owed to EP Energy under this Agreement or under any applicable JOA (or to the joint account under any applicable JOA) from any amounts owed to Partner or its Affiliates, whether under this Agreement or otherwise, and to only remit to Partner or its Affiliates pursuant to clause (iv) above their aggregate net share of any such amounts, if any, owed by EP Energy. Any amounts due to Partner pursuant to Section 5.2(a)(iv) shall be paid to Partner (x) with respect to revenues from the production of oil, no later than the later of (a) 31 days following the last day of the month in which such oil was sold or (b) within nine Business Days after receipt of funds by EP Energy and (y) with respect to revenues from the production of gas, no later than the later of (a) 62 days following the last day of the month in which such gas was sold or (b) within nine Business Days after receipt of funds by EP Energy.

(b) If the Partner Monthly Revenues are insufficient to satisfy and discharge all or a portion of the amounts due and payable under Sections 5.2(a)(i) – (iii) in any given Calendar Month or anticipated to be due and payable within the next succeeding month, then, subject to Section 4.3 (to the extent applicable), EP Energy, at its option, will either issue billing statements and invoices to Partner for Partner’s then-current Working Interest share of Well Costs (including the Partner Qualified Cost Cap Make-Up Amount, if applicable) and for applicable Carried Costs that EP Energy has incurred or incurs and that are due and payable in connection with Development Operations, or issue a request to Partner to advance (i) Partner’s then-current Working Interest share of Well Costs, (ii) the Carried Costs and/or (iii) if applicable, such Qualified Costs equal to no more than the then outstanding Partner Qualified Cost Cap Make-Up Amount as described in Section 4.3, in each case, that EP Energy reasonably anticipates to be due and payable that will be paid by EP Energy within the next succeeding Calendar Month in connection with Development Operations (in each case, consistent with EP Energy’s ordinary course of business and past practices); provided that EP Energy will not issue any such billing statements, invoices or advance billing requests more than once each Calendar Month.

(c) In response to each billing statement, invoice or advance billing request properly issued by EP Energy hereunder, Partner will pay or advance to EP Energy all such

amounts thereunder within 15 Business Days of receiving such billing statement, invoice or advance billing request or by the first day of the Calendar Month for which the advance is requested, whichever is later and otherwise in accordance with the accounting procedure attached to the applicable JOA. For the avoidance of doubt, no billing statement, invoice or advance billing request delivered by EP Energy hereunder or under any JOA may include (and if Partner previously furnished documentation and explanation to EP Energy, Partner may reduce its payment of such billing statement, invoice or advance billing request by) amounts attributable to: (i) an incorrect Working Interest that is higher than Partner’s actual Working Interest for the applicable Well (in each case, subject to Partner’s obligation to pay the Carried Costs); (ii) a project or AFE requiring approval of Partner that Partner has not approved or is not otherwise obligated to pay under this Agreement; (iii) Qualified Costs in excess of the Partner Qualified Cost Cap as described in Section 4.3; or (iv) a Well in which Partner no longer owns a Working Interest, and for which Partner has furnished EP Energy a copy of the executed assignment or letter-in-lieu; provided, that notwithstanding the foregoing, Partner shall remain responsible for paying billing statements or invoices attributable to the interest it sold or transferred for any billing statement or invoice rendered during the 30-day period following EP Energy’s receipt of such written notice.

Section 5.3 Memorandum. Concurrently with the execution hereof, each Party will execute, acknowledge and deliver the Memorandum set forth in Exhibit J. Each Party agrees to execute and deliver such other amendments to the Memorandum from time to time to reflect any Conveyed Interest assigned pursuant to Section 2.3 or Section 4.6.

Section 5.4 Audit. Partner shall have the right, at its own cost and expense (which shall not be included in the calculation of the IRR), upon 30 days’ written notice, but in no event more frequently than once per Calendar Year, and during reasonable working hours to perform an audit of EP Energy’s accounts and records related to the Carried Costs, Well Costs, Qualified Costs, Lease Operating Expenses, calculation of IRR and any account maintained under Associated Agreements for the benefit of both Parties for the preceding 24-Calendar-Month period. Partner shall have the right to obtain access to and copies of the relevant portion of the accounts and records which includes financial information, reports, charts, calculations, and accounting records of EP Energy to the extent reasonably necessary to verify EP Energy’s accounting of costs, expenses and proceeds, or related to the Carried Costs, Well Costs, Qualified Costs or Lease Operating Expenses paid by Partner. The accuracy of any cost or expense included in any billing statement, invoice or advance billing request made pursuant to this Agreement shall be conclusively presumed to be correct after the 24-Calendar-Month period following the Calendar Month in which such billing statement, invoice or advance billing request was generated or prepared, if not disputed in writing prior thereto. Audits conducted pursuant to this Section 5.4 shall otherwise be conducted in accordance with the “Expenditure Audit” procedures set forth in the accounting procedure attached to the EP/Apollo JOA.

Article VI
DEFAULTS

Section 6.1 Defaults.

(a) In the event that (i) any Party fails to pay its share of the Well Costs pursuant to this Agreement or Partner fails to pay any Carried Costs or any Qualified Costs that is included in the Partner Qualified Cost Cap Make-Up Amount as described in Section 4.3, (ii) EP Energy breaches Article V.D.2 or Article V.D.3 of the EP/Apollo JOA or (iii) EP Energy fails to make payments to Partner in accordance with the last sentence of Section 5.2(a), in each case, on or before the Initial Default Date (such defaulting Party, a “Defaulting Party”), then (A) the other Party (the “Non-Defaulting Party”) may provide written notice of such default (a “Default Notice”) to such Defaulting Party (which Default Notice will include a statement of the amount of money that the Defaulting Party has failed to pay) and (B) in addition to (1) the remedies available to any Non-Defaulting Party under any Associated Agreements, (2) those remedies that occur automatically pursuant to Section 6.2, and (3) any and all other rights and remedies under this Agreement or at Law or in equity, the Non-Defaulting Party will be entitled to exercise, in its sole discretion, the remedy set forth in Section 6.4 during the period of time beginning 30 days from the date of a Defaulting Party’s receipt of a Default Notice (if such Defaulting Party remains in default) until the date upon which the Total Amount in Default has been fully cured (the “Default Period”).

(b) All amounts in default and not paid when due under this Agreement will bear interest at the Agreed Rate from the due date to the date of payment in full.

(c) In the event a Party disputes any amounts owed to the other Party, then such disputing Party shall provide prompt written notice thereof and the reason for such dispute. If the Parties are unable to agree on such amount subject to such dispute within 10 Business Days of receipt by the non-disputing Party of such notice from the disputing party, then either EP Energy or Partner may request the Accounting Arbitrator (as such Person is determined in accordance with Section 2.6(b)) to decide such dispute. EP Energy and Partner will, within 10 Business Days after the agreement by the Accounting Arbitrator to serve, summarize its position with regard to such dispute in a written document of 20 pages or less and submit such summaries to the Accounting Arbitrator. Within 20 Business Days after receiving the Parties’ respective submissions, the Accounting Arbitrator will render a decision choosing either EP Energy’s position or Partner’s position with respect to each matter addressed in any such dispute notice, based on the materials submitted to the Accounting Arbitrator as described above, and in accordance with this Agreement. Any decision rendered by the Accounting Arbitrator pursuant to this Section 6.1(c) will be final, conclusive and binding on EP Energy and Partner and will be enforceable against the Parties in any court of competent jurisdiction. The costs and expenses of the Accounting Arbitrator will be borne one-half by Partner and one-half by EP Energy (which costs and expenses shall not be included in the calculation of the IRR). Upon resolution of the disputed amount and payment in full by the Defaulting Party of the amount due (as agreed to by the Parties or determined by the Accounting Arbitrator) together with accrued interest, if any, such Default Notice shall be deemed withdrawn. All disputed amounts due and owing by the disputing Party (as agreed to by the Parties or determined by the Accounting Arbitrator) shall be paid within 10 Business Days of the Parties’ agreement or receipt of the Accounting Arbitrator’s decision, as applicable.

(d) During the Default Period, if applicable, the Defaulting Party will be deemed to have approved, and will join with the Non-Defaulting Party in taking, any actions approved by the Non-Defaulting Party during the Default Period that must be undertaken to prevent a Lease in effect from expiring or that cannot be conducted by only one party under the terms of any JOA.

Section 6.2 Certain Automatic Remedies for a Default. Subject to Section 6.4 and Section 6.5, unless the Non-Defaulting Party elects in writing to waive any or all of the following, during the Default Period, the Defaulting Party will automatically not be entitled to:

(a) except for Partner’s right to approve or reject the Proposed Second Tranche Drilling Program (or any amendment to an Approved Drilling Program for which Partner’s approval is required pursuant to this Agreement), make, or elect to participate or not to participate in, any new proposal under this Agreement or any JOA;

(b) except for (i) Partner’s right to approve or reject the Proposed Second Tranche Drilling Program (or any amendment to an Approved Drilling Program for which Partner’s approval is required pursuant to this Agreement) and (ii) Partner’s right to consent to (or withhold consent from) any contract under Section 3.8(c), vote on any matter with respect to which approval is required under the express terms of this Agreement or any Associated Agreement (excluding any amendment or waiver of the terms of any such agreement);

(c) with respect to Partner, access any data or information relating to any Development Operation conducted under this Agreement or any Associated Agreement;

(d) except for a Permitted Pledge or a Permitted Pledge Transfer, make any Transfer, assignment or other transfer, which would otherwise be permitted pursuant to Article VIII;

(e) withhold consent to any Transfer by a Non-Defaulting Party pursuant to Article VIII; or

(f) receive its Entitlement from the Farmout Wells and the Non-Defaulting Party will have the right to collect such Entitlement; provided that, if Partner is the Defaulting Party, the proceeds from all such Entitlements will be deemed, first, to apply to the portion of the Total Amount in Default that relates to any Carried Costs and, second, and only to the extent that all defaults have been cured with respect to the Carried Costs, to the remainder of the Total Amount in Default.

Section 6.3 Additional Partner Remedy. In the event EP Energy is the Defaulting Party, Partner shall have the right to offset the Total Amount in Default against any outstanding Well Costs owed by Partner to EP Energy under the terms of this Agreement or any JOA.

Section 6.4 Specific Performance. Each Party will be entitled to seek specific performance of any of the other Party’s obligations under this Agreement or any Associated Agreement; provided that Partner shall not have the right to seek specific performance of operational

or marketing obligations that are subject to the provisions of Section 3.3 except to the extent EP Energy’s breach of such obligations has met or exceeded the liability thresholds set forth in Section 3.3.

Section 6.5 Cumulative and Additional Remedies. Subject to Section 6.4, the rights and remedies granted to each applicable Party in this Article VI will be cumulative, not exclusive, and will be in addition to any other rights and remedies that may be available to the Parties at law, in equity or otherwise. Each right and remedy available to a Party may be exercised from time to time and so often and in such order as may be considered expedient by such Party in its sole discretion.

Article VII
OPTION WELLS

Section 7.1 Option Wells. So long as Partner is not a Defaulting Party, from and after the date of Completion of the last Farmout Well in the Second Tranche Drilling Program (if Partner does not approve, or is deemed to have rejected, the Proposed Second Tranche Drilling Program by the deadline set forth in Section 4.2(c), from and after the date of Completion of the last Farmout Well in the First Tranche Drilling Program) until the fifth anniversary after the expiration of the Availability Period (the “Option Period”), Partner will have the right to participate in any Well proposed to be spud as an Infill Well to be drilled and Completed in the same Bench of the Farmout Well that such Infill Well offsets (each, an “Option Well”), subject to the terms of Section 7.2 and Section 7.3. EP Energy shall not have the right to propose any Option Wells until the Option Period begins. During the Option Period, the remaining provisions of this Article VII will apply.

Section 7.2 Election Regarding Option Wells. During the Option Period, from time to time, if EP Energy desires to drill any Option Well, then EP Energy shall propose the drilling of such Option Well or propose the drilling of a group of Option Wells to Partner by providing written notice (the “Option Well Notice”) to Partner of such proposal, which notice will include only items (a), (b), (c), (e) and (h) of the Required Plan Terms. Partner will have 30 days following its receipt of an Option Well Notice within which to elect to participate in the Option Well(s) described in such Option Well Notice. If Partner fails to respond within such 30-day period, it will be deemed to have elected not to participate in such Option Well(s); provided, however, if EP Energy fails to spud such Option Well (or the first Option Well in any Option Well Group) within 180 days following such 30-day period, then Partner shall not be deemed to have elected not to participate in such Option Well(s) and EP Energy shall be required to send a new Option Well Notice should it decide to spud such Option Well(s) thereafter. If Partner elects not to, or is deemed to have elected not to, participate in any grouping of Option Well(s) (which, for the avoidance of doubt, does not include any election to withdraw (or any deemed withdrawal hereunder) from Development Operations in accordance with Section 2.1(d), Section 3.9(b), Section 3.13, Section 4.2 or Section 7.3), Partner’s rights to the Option Wells and Option Period will terminate immediately and this Article VII will no longer apply (but, for the avoidance of doubt, Section 3.14 shall continue to apply to such Wells); provided that if and only if the first Option Well Notice delivered by EP Energy includes more than five Option Wells and Partner elects not to, or is deemed to have elected not to, participate in such Option Wells, Partner’s rights with respect to additional Option Wells will not terminate as a result of such election.

Section 7.3 Participation. If Partner elects to participate in the Option Wells pursuant to Section 7.2, Partner must participate in all (but not less than all) of the Option Wells set forth in an Option Well Notice (such Option Wells, the “Elected Option Wells”, and each such group of Option Wells, an “Elected Option Well Group”), then all of such Elected Option Wells will be Completed in accordance with the applicable Option Well Notice on a head’s up basis (which shall mean each Party participating according to its Residual Working Interest Share); provided that Partner may review the proposed Option Well Notice and, prior to or simultaneously with such approval, elect to exclude (in its sole discretion) certain Option Wells included in such proposed Option Well Notice if Partner reasonably believes that (i) any such Option Wells are subject to an Environmental Condition that would cause a reasonably prudent operator not to drill such Wells in its ordinary course of business or (ii) such Option Wells are subject to an uncured title issue that would cause a reasonably prudent operator not to drill such Wells in its ordinary course of business. With respect to each Elected Option Well, prior to assigning Partner its interest in such Elected Option Well, EP Energy shall obtain recordable lien releases (in form reasonably acceptable to Partner) executed by the holders of any Existing Secured Debt pursuant to which such holders release the liens covering the interests to be assigned to Partner that secure such Existing Secured Debt.

Article VIII
TRANSFER RESTRICTIONS

Section 8.1 Restrictions on Transfer; Change in Control.

(a) Transfer Restrictions during the Availability Period.

(i) Except as provided in Section 8.5, until the expiration of the Availability Period, subject to Section 8.1(c), Partner will not, and will cause its Affiliates not to, (A) Transfer all or any portion of the Conveyed Interests, (B) Transfer all or any part of its rights or obligations under this Agreement or any Associated Agreement, (C) undergo a Partner Well Location Change of Control or (D) undergo a Change in Control, in each case without the prior written consent of EP Energy (which may be granted or withheld in EP Energy’s sole discretion); provided, however, that this Section 8.1(a)(i) will not apply if (X) such Transfer or Partner Well Location Change of Control involves all (but not less than all) of the Conveyed Interests and other properties included in a wider transaction (i.e., a “package deal”) where the value attributed in good faith to the Farmout Wells and Elected Option Wells by Partner and the Third Party is less than 15% of the value of such wider transaction (“Partner Package Transfer”) and (Y) to the extent that Partner desires to effect a Partner Package Transfer, Partner has agreed to (1) fully fund its share of the Well Costs and Carried Costs relating to any Farmout Wells or Elected Option Wells (as applicable) included in the then-effective Approved Drilling Program that have not been Completed, or (2) the Third Party purchaser provides credit support reasonably acceptable to EP Energy equal to the amount required to fund its share of the Well Costs and Carried Costs relating to any Farmout

Wells or Elected Option Wells (as applicable) included in the then-effective Approved Drilling Program that have not been Completed.

(ii) With respect to any Farmout Wells and Well Locations, until the expiration of the Availability Period, EP Energy will not, and will cause its Affiliates not to, (1) Transfer all or any portion of such Farmout Wells and Well Locations, (2) Transfer all or any part of its rights or obligations under this Agreement or any Associated Agreement or (3) undergo an EP Energy Well Location Change of Control, in each case without the prior written consent of Partner (which may be granted or withheld in Partner’s sole discretion); provided, however, this Section 8.1(a)(ii) will not apply if (I) such Transfer by EP Energy (or its Affiliates) or EP Energy Well Location Change of Control involves all (but not less than all) of EP Energy’s Working Interest corresponding to such Wells and Well Locations, and other properties included in a wider transaction (i.e., a “package deal”) where the value attributed in good faith to the Farmout Wells and remaining Well Locations (if any) by EP Energy and the Third Party is less than 15% of the value of such wider transaction (“EP Energy Package Transfer”) and (II) to the extent that EP Energy desires to effect an EP Energy Package Transfer, EP Energy has agreed to (a) fully fund its share of the Well Costs relating to any Farmout Wells or Elected Option Wells (as applicable) included in the then-effective Approved Drilling Program that have not been Completed, or (b) the Third Party purchaser provides credit support reasonably acceptable to Partner equal to the amount required to fund its share of the Well Costs relating to any Farmout Wells or Elected Option Wells (as applicable) included in the then-effective Approved Annual Drilling Program that have not been Completed.

(b) Transfers after the Availability Period. In addition to Partner’s rights under Section 8.5, after the expiration of the Availability Period, subject to Sections 8.1(d) through 8.1(f), Section 8.2 (with respect to any Transfer by Partner), and Section 8.4 hereof, and the applicable Tax Partnership Agreement, (i) Partner and its Affiliates will be permitted to (A) Transfer or undergo a Partner Well Location Change of Control, in each case, with respect to all (but not less than all) of its interest in the Development Interests associated with a Well Group or Elected Option Well Group for which all Farmout Wells or Elected Option Wells (as applicable) included in such Well Group or Elected Option Well Group have been Completed, together with a corresponding portion of its rights or obligations under this Agreement or any Associated Agreement to a single transferee with respect to such Well Group or Elected Option Well Group, (B) Transfer all or any portion of Partner’s equity interests, directly or indirectly, or (C) undergo a Change in Control and (ii) EP Energy and its Affiliates will be permitted to (x) Transfer all or any portion of any Farmout Wells and Well Locations, together with a corresponding portion of its rights or obligations under this Agreement or any Associated Agreement (provided that prior to Reversion of an applicable Well Group, EP Energy and its Affiliates will only be permitted to Transfer all (but not less than all) of the Farmout Wells and Well Locations included in such Well Group), or (y) undergo an EP Energy Well Location Change of Control.

(c) Permitted Transfers; Financing. Notwithstanding the restrictions on Transfer set forth in Section 8.1(a) and Section 8.1(b), but subject to the requirements of Sections 8.1(d) through 8.1(f), and Section 8.4, either Party may Transfer all (but not less than all) of its interests in the Development Interests associated with a Well Group or Elected Option Well Group, together with a corresponding portion of its rights and obligations under this Agreement or any Associated Agreement, to any Affiliate of such Party; provided that, unless the non-transferring Party is satisfied with the creditworthiness of such Affiliate of the transferring Party, determined in its reasonable discretion, no such Transfer will relieve such Party of any of its or its Affiliates’ obligations under this Agreement or any Associated Agreement, and the transferring Party will remain primarily liable for all such obligations, whether incurred before or after such Transfer. In the event Partner Transfers a portion of its interests in the Development Interests associated with a Well Group or Elected Option Well Group to one or more Affiliates, Partner shall designate one Person that is managed by the Partner Ultimate Parent to make elections and receive notices under this Agreement, and notice provided by EP Energy to such Person shall be deemed to satisfy the notice delivery requirement under Section 14.3. For the avoidance of doubt, Partner may only Transfer to its Affiliates pursuant to this Section 8.1(c) on a Well Group or Elected Option Well Group basis and if such Affiliate ceases to be an Affiliate of Partner within one year of the consummation of such Transfer, the Development Interests Transferred to such Affiliate shall be Transferred back to Partner immediately prior to such event that causes such Affiliate to cease to be an Affiliate of Partner. Notwithstanding Sections 8.1(a) and 8.1(b), any Transfer, assignment or other transfer by a Party to an Affiliate of such Party will be subject to this Section 8.1(c). Partner, EP Energy and their respective Affiliates may encumber all or any portion of its interests in the Development Interests in connection with a Permitted Pledge and the same will not be deemed to be a Transfer. A transfer by a Party made in connection with a secured party’s exercise of remedies of a Permitted Pledge under a customary reserve based lending facility or any transfer made after commencement of a bankruptcy or insolvency proceeding respecting the Party bound by the Permitted Pledge and approved by the court or tribunal having jurisdiction over such proceeding (whether by a secured party or any other transferee or assignee) (a “Permitted Pledge Transfer”) will not be deemed to be a Transfer and shall be made free and clear of all rights and obligations under this Agreement, other than, with respect to Partner, Partner’s obligation to pay (A) the Carried Costs, (B) if applicable, any Partner Qualified Cost Cap Make-Up Amount and (C) Partner’s share of the Well Costs with respect to the Farmout Wells included in such Permitted Pledge Transfer and EP Energy’s rights in and to such Farmout Wells or Elected Option Wells (as applicable) upon Reversion. Notwithstanding anything herein to the contrary, in the event of a Permitted Pledge Transfer or any other Transfer permitted under this Article VIII with respect to all (but not less than all) of the Farmout Wells or Elected Option Wells (as applicable) included in one or more (but not all) Well Groups or Elected Option Well Groups, as applicable, the Parties agree to remove the affected Well Group(s) or Elected Option Well Group(s) from the EP/Apollo JOA and, in such event, the applicable Party and the applicable transferee will execute a joint operating agreement in the form of the EP/Apollo JOA covering only such affected Well Group(s) or Elected Option Well Group(s) and the Parties will execute and record an amendment to the memorandum of EP/Apollo JOA removing the Wells subject to such Permitted Pledge Transfer or such other permitted

Transfer from all obligations thereunder. Notwithstanding anything herein to the contrary, subject to Section 2.4, EP Energy shall not in any way mortgage or pledge any Development Interest with respect to a Well Location or Elected Option Well prior to Partner being assigned its Conveyed Interest with respect thereto.

(d) Liability of Transferor/Transferee for a Transfer. Subject to Section 8.1(c), no Transfer permitted under Section 8.1(b) will relieve any Party of any of its or its Affiliates’ obligations under this Agreement or any Associated Agreement except to the extent that such obligations are incurred from and after such Transfer, and provided, that the transferring Party will be released from such obligations only to the extent assumed in writing by such transferee.

(e) Transfers by Defaulting Parties. Notwithstanding anything to the contrary in this Section 8.1, no Defaulting Party may, and any Defaulting Party will cause its Affiliates not to, Transfer to a Third Party all or any part of its interests in the Farmout Wells or Elected Option Wells (as applicable) or Transfer all or any part of its rights or obligations under this Agreement or any Associated Agreement, unless and until (or simultaneous with the time that) the Total Amount in Default is paid by such Defaulting Party or any other Person on behalf of such Defaulting Party.

(f) Transfers in Violation of this Article VIII. Any Transfer, attempted Transfer or Change in Control or attempted Change in Control in violation of this Article VIII will be, and is hereby declared, null and void ab initio.

Section 8.2 Right of First Offer.

(a) Subject to Section 8.1, until the earlier to occur of (i) the expiration of the Availability Period and (ii) Reversion of the applicable Well Group, if any Party desires to Transfer (such Person, a “Transferor”) any portion of its interests in the Development Interests associated with a Well Group (for clarity, such portion being all or an undivided interest in each Well within such Well Group) to a Third Party (except for any EP Energy Package Transfer or any Partner Package Transfer), then such Transferor will give to the other Party (such other Party, the “ROFO Holder”) written notice (a “ROFO Notice”) setting forth the portion of such Development Interests in such Wells within such Well Group to be Transferred (the “Offered Interest”). For a period of 30 days following receipt of a ROFO Notice (the “ROFO Offer Period”), a ROFO Holder will have the right but not the obligation to make an offer to the Transferor to acquire all but not less than all of the Offered Interest set forth in such ROFO Notice. If the ROFO Holder elects to make an offer within the ROFO Offer Period, the ROFO Holder shall deliver to Transferor a letter (the “ROFO Offer Letter”) signed by the ROFO Holder notifying the Transferor of the proposed transaction and providing the following information: (A) the proposed purchase price for the Offered Interest (the “ROFO Offered Price”); (B) any material terms and conditions of ROFO Holder’s offer to purchase all, but not less than all, of the Offered Interest; and (C) ROFO Holder’s binding offer to purchase from the Transferor all, but not less than all, of the Offered Interest for the ROFO Offered Price on the terms and conditions contained in the ROFO Offer Letter (each, a “ROFO Offer”).

(b) Within 10 Business Days following receipt by the Transferor of the ROFO Offer Letter (the “Transferor Acceptance Period”), the Transferor shall notify the ROFO Holder whether or not it is electing to accept the ROFO Offer (such notification, if affirmative, shall be referred to hereinafter as the “Transferor Acceptance”); provided, however, that the Transferor shall be under no obligation to accept any ROFO Offer; and provided, further, that failure by the Transferor to so notify the ROFO Holder whether or not it is electing to accept any ROFO Offer within the Transferor Acceptance Period shall be deemed a rejection of the ROFO Offer by the Transferor. The Parties will cooperate with each other to consummate the purchase of the Offered Interest by the ROFO Holder as promptly as practicable following the delivery of a Transferor Acceptance. If the Transferor rejects any ROFO Offer, then the Transferor may thereafter Transfer the Offered Interest to a Third Party at a price no less than the ROFO Offered Price and on such other terms and conditions not more favorable in the aggregate to the acquiring party than those specified in the ROFO Offer Letter for a period not to exceed 120 days from the date of such rejection (subject to reasonable extension to the extent necessary to satisfy applicable regulatory approvals (if any)); provided that the Transferor agrees to provide written notice to the ROFO Holder at least 10 Business Days prior to its execution of any definitive agreement with respect to any such Transfer. After such 120-day period (as extended, to the extent applicable), any proposed Transfer shall once again be subject to the terms and conditions of this Section 8.2 to the extent provided herein.

Section 8.3 [Reserved].

Section 8.4 Documentation for Transfers. Any Transfer by any Party that is otherwise permitted pursuant to other provisions of this Article VIII will not be effective unless and until the other Party has received a document executed by both the transferring Party (or its legal representative) and the permitted transferee (or its legal representative) that includes: (a) the identity and notice address of the permitted transferee; (b) such permitted transferee’s express agreement in writing to (i) be bound by and fully and timely perform all of the terms and conditions of this Agreement and any applicable Associated Agreement to the extent applicable to the transferred interest (including, for the avoidance of doubt, Section 3.7 and, with respect to EP Energy, its obligations to provide the Services described on Exhibit K) and (ii) assume an undivided interest (in an amount equal to the Working Interest Share being Transferred to the permitted transferee) of all of the liabilities and obligations of the transferring Party under this Agreement and any applicable Associated Agreements (which will include Section 2.5); (c) a description of the interests being Transferred; and (d) representations and warranties to the non-transferring Party from the transferring Party that the Transfer was made in accordance with applicable Law (including state and federal securities Law) and the terms and conditions of this Agreement and any applicable Associated Agreements. Each permitted Transfer will be effective against the non-transferring Party as of the first Business Day of the Calendar Month immediately following the non-transferring Party’s receipt of the document required by this Section 8.4, from which time the transferee will (subject to this Article VIII) be deemed a “Party” to this Agreement in respect of the interest transferred.

Section 8.5 Tag-Along Right.

(a) Subject to Section 8.1(a)(ii), in the event EP Energy intends to Transfer all or any portion of EP Energy’s interest in the Development Interests (the “Tag Assets”), including a permitted EP Energy Package Transfer, EP Energy will provide to Partner a written notice of such intent that includes (i) a description of the Tag Assets, (ii) the name of the proposed transferee, (iii) the anticipated date on which such proposed Transfer shall take place, which cannot be less than 30 days after the date on which such Transfer Notice is delivered and (iv) the material terms and conditions of the proposed Transfer (the “Transfer Notice”). EP Energy will cause the proposed transferee to propose a purchase price that includes Partner’s and EP Energy’s collective Working Interest in the Farmout Well(s) and Elected Option Well(s) described in the transfer notice and a bona fide allocation of value between the Farmout Well(s) and Elected Option Well(s) (including Partner’s and EP Energy’s collective Working Interest in such Wells), on the one hand, and all other assets (if any) included in the transaction subject to a Transfer Notice, on the other hand. EP Energy may discuss the proposed allocation with the transferee in good faith, but EP Energy shall not intentionally interfere with such bona fide allocation.

(b) Partner will have the right (but not the obligation) within 30 days following receipt of the Transfer Notice to elect in writing to Transfer to the transferee its corresponding interest in and to the interest in such Farmout Well(s) and Elected Option Well(s) subject to the proposed Transfer by EP Energy (the “Partner Tag Interest”). If Partner does not so notify EP Energy of its election within such 30-day period, Partner will be deemed to have waived its right to include the Partner Tag Interest in such Transfer (the “Tag Along Sale”).

(c) If Partner notifies EP Energy in accordance with Section 8.5(b) that it elects to participate in the Tag Along Sale and the transferee agrees to purchase both the Tag Assets and the Partner Tag Interest, then (i) the Partner Tag Interest shall be Transferred on substantially the same terms and conditions described in the Transfer Notice; provided that (A) any representations and warranties relating specifically to any Party shall be made only by that Party, (B) any representations and warranties with respect to operational matters to be made by Partner shall be qualified to its knowledge, and (C) any indemnification provided by the Parties in the Transfer shall be made on a several, and not joint, basis and (ii) EP Energy and Partner shall enter into separate but substantially similar purchase and sale agreements with the transferee.

(d) Notwithstanding anything to the contrary herein, prior to the Reversion, regardless whether the transferee elects to purchase the Partner Tag Interest, EP Energy may consummate the sale of the Tag Assets with the transferee and in no event will there be any reduction of the Tag Assets as a result of Partner’s election.

(e) From and after the Reversion, if Partner notifies EP Energy in accordance with Section 8.5(b) that it elects to participate in the Tag Along Sale but the transferee thereof does not desire to purchase the entirety of the Tag Assets and the Partner Tag Interest, then the interests in the assets and properties comprising the Tag Assets to be sold to such transferee by each of EP Energy and Partner will be reduced proportionately (in the ratio of the interests held by the applicable Party in the assets and properties comprising the Tag

Assets to the entire interest in the assets and properties comprising the Tag Assets that is held by both Parties) and each Party shall sell their reduced interest in the assets and properties comprising the Tag Assets to such transferee (and retain such Party’s residual interest in such assets and properties), in which case, the transfer by Partner shall be in accordance with Section 8.5(c)(i) and (ii) above as to the interest to be transferred by such Partner. From and after the Reversion, if Partner notifies EP Energy in accordance with Section 8.5(b) that it elects to participate in the Tag Along Sale but the transferee thereof does not desire to purchase any of the Partner Tag Interest in accordance with the foregoing, then EP Energy shall not sell or transfer any portion of the Tag Assets to such transferee.

(f) If Partner elects not to participate in the Tag Along Sale, then EP Energy shall be free to Transfer the Tag Assets described in the Transfer Notice; provided that (i) the Transfer must be on terms no more favorable, in the aggregate, to those provided in the Transfer Notice (including the consideration paid to EP Energy therefor), and (ii) the proposed Transfer must be completed within 120 days following Partner’s election not to participate in the Tag Along Sale (subject to reasonable extension to the extent necessary to satisfy applicable regulatory approvals (if any)). If EP Energy fails to Transfer the Tag Assets within 120 days following Partner’s election not to participate in the Tag Along Sale (subject to reasonable extension to the extent necessary to satisfy applicable regulatory approvals (if any)), then the Tag Assets shall again be subject to this Section 8.5.

(g) If Partner elects to participate in the Tag Along Sale, the proceeds of such transaction shall be allocated by the transferee in accordance with the applicable purchase and sale agreements.

(h) Upon the request of EP Energy, Partner will enter into a customary confidentiality agreement with EP Energy pursuant to which Partner will agree to keep all information provided by EP Energy or any of its representatives or Affiliates to Partner related to the proposed Transfer (including the existence of such proposed Transfer) confidential effective as of the first day EP Energy or any of its representatives or Affiliates provides any such information to Partner.

Section 9.3 Tax Information. Each Party shall provide to the other Party, in a timely manner and at such Party’s sole expense, with information with respect to Development Operations conducted by such Party as it may reasonably request for preparation of its Tax Returns or responding to any audit or Tax proceeding with respect to Taxes.

Other than with respect to EP Energy’s representations and warranties made in Section 11.1 and EP Energy’s covenants made herein and in the Associated Agreements, in making its decision to enter into this Agreement and to consummate the transactions contemplated hereby, Partner (a) has relied or will rely solely on its own independent investigation and evaluation of the Development Interests and the advice of its own legal, Tax, economic, environmental, engineering, geological and geophysical advisors and the express provisions of this Agreement and not on any comments, statements, projections or other materials made or given by any representatives or consultants or advisors of EP Energy, and (b) has satisfied or will satisfy itself through its own due diligence as to the environmental and physical condition of and contractual arrangements and other matters affecting the Development Interests.

(i) Brokers’ Fees. Partner has incurred no liability, contingent or otherwise, for brokers’ or finders’ fees relating to the transactions contemplated by this Agreement for which EP Energy or EP Energy’s Affiliates will have any responsibility.

(j) Accredited Investor. Partner is an “accredited investor,” as such term is defined in Regulation D of the Securities Act of 1933, as amended, and will acquire the Conveyed Interests for its own account and not with a view to a sale or distribution thereof in violation of the Securities Act of 1933, as amended, and the rules and regulations thereunder, any applicable state blue sky Laws or any other applicable securities Laws.

Section 11.3 Update to Schedules. Partner agrees that, (a) with respect to the representations and warranties of EP Energy contained in this Agreement pertaining to the Second Tranche Drilling Program, EP Energy shall have the continuing right until the earlier of (i) the date of approval of the Proposed Second Tranche Drilling Program by Partner or (ii) the date that is 10 Business Days prior to the Second Tranche Approval Deadline and (b) with respect to the representations and warranties of EP Energy contained in this Agreement pertaining to an Additional Well Notice, EP Energy shall have the continuing right until the earlier of (a) the date of election to participate in the Additional Well set forth therein by Partner or (b) the date that is 20 days after the delivery of such Additional Well Notice by EP Energy (the “Schedule Amendment Deadline”) to add, supplement or amend the Schedules to its representations and warranties with respect to any matter regarding Well Locations, Farmout Wells or Additional Wells arising after the Execution Date (or discovered after the Execution Date) that would be required to be set forth or described in such Schedules, whether or not a Schedule currently exists for the applicable representations and warranties. Prior to the Schedule Amendment Deadline, with respect to the Well Locations, Farmout Wells and Additional Wells indicated in such Proposed Second Tranche Drilling Program or Additional Well Notice, as applicable, the Schedules to EP Energy’s representations and warranties

contained in this Agreement shall be deemed to include only that information contained therein as of the later of (x) the Execution Date and (y) the date of last amendment to the Schedules approved or deemed approved in accordance with this Section 11.3, and shall be deemed to exclude all information contained in any addition, supplement or amendment thereafter; provided, however, that if the Proposed Second Tranche Drilling Program is approved or Partner elects to participate the applicable Additional Well, as applicable, then Partner will not be entitled to make a claim for EP Energy’s breach of any representation or warranty on account of all such matters disclosed pursuant to any such addition, supplement or amendment at or prior to the Schedule Amendment Deadline (whether pursuant to the terms of this Agreement or otherwise) with respect to such Proposed Second Tranche Drilling Program or such Additional Well Notice, as applicable. For the avoidance of doubt, with respect to all matters disclosed pursuant to any such addition, supplement or amendment to the Schedules described in this Section 11.3, if Partner rejects the Proposed Second Tranche Drilling Program or elects not to participate in such Additional Well, Partner will also be deemed to have waived all such matters to the extent relating to such Proposed Second Tranche Drilling Program or such Additional Well Notice, as applicable, and Partner will not be entitled to make a claim with respect thereto pursuant to the terms of this Agreement or otherwise with respect to the Second Tranche Drilling Program or such Additional Well Notice, as applicable.

(d) the performance of the Services (excluding, for the avoidance of doubt, any breach by EP Energy of its obligation to perform the Services as described in Section 3.11), except to the extent arising out of any EP Energy Indemnified Party’s gross negligence or willful misconduct.

Section 12.4 Limitation on Liability.

(a) Except as provided in Section 12.4(c), EP Energy will not have any liability for any indemnification under Section 12.2(a) of this Agreement (i) for any individual Liability unless the amount with respect to such Liability exceeds $50,000, and (ii) until and unless the aggregate amount of all Liabilities for which Claim Notices are delivered by Partner exceeds the Indemnity Deductible, and then, only to the extent such Liabilities exceed the Indemnity Deductible.

(b) Except as provided in Section 12.4(c), notwithstanding anything to the contrary contained in this Agreement, EP Energy will not be required to indemnify any Partner Indemnified Parties for aggregate Liabilities arising pursuant to EP Energy’s (i) indemnity obligations in Section 12.2(a) in excess of an amount equal to $45,000,000, or (ii) for aggregate Liabilities arising pursuant to EP Energy’s indemnity obligations in Section 12.2(b) with respect only to EP Energy’s obligation under Section 3.11(a) in excess of an amount equal to the aggregate Management Fees actually received by EP Energy, other than Liabilities arising out of any EP Energy Indemnified Party’s gross negligence or willful misconduct (subject to such limitation, the “MSA Liability Cap”).

(c) Section 12.4(a) and Section 12.4(b) will not apply to, and will in no way limit, any Liability or indemnity of EP Energy in respect of or arising out of (i) Section 12.2(a) for the breach of the Specified Representations or (ii) Sections 12.2(b) through 12.2(e); provided that EP Energy’s liability in respect of or arising out of Section 12.2(b) solely for the breach of Section 3.11(a) shall be limited as set forth in Section 12.4(b).

(d) For purposes of determining whether there has been a breach of any of EP Energy’s representations and warranties for which Partner is entitled to indemnification hereunder and the amount of any Liabilities resulting therefrom, any dollar or materiality qualifiers in EP Energy’s representations or warranties shall be disregarded.

THE DEFENSE, INDEMNIFICATION, HOLD HARMLESS, RELEASE AND ASSUMED OBLIGATIONS PROVISIONS PROVIDED FOR IN THIS AGREEMENT WILL BE APPLICABLE WHETHER OR NOT THE LIABILITIES, LOSSES, COSTS, EXPENSES AND DAMAGES IN QUESTION AROSE OR RESULTED SOLELY OR IN PART FROM THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR VIOLATION OF LAW OR BY ANY INDEMNIFIED PARTY, EXCEPT FOR SUCH INDEMNIFIED PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. PARTNER AND EP ENERGY ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS “CONSPICUOUS.”

Section 12.6 Exclusive Remedy. Notwithstanding anything to the contrary contained in this Agreement, except as set forth in Article VI, including Section 6.4 (subject to the limitations thereof), and Article XIII, and except for the special warranty contained in each Assignment and except for the Parties’ rights and remedies under the EP/Apollo JOA, the Parties agree that Section 12.2 and Section 12.3 contain the Parties’ exclusive remedies against each other with respect to breaches of the representations, warranties, covenants and agreements contained in this Agreement (except for the breach of EP Energy’s representation in Section 11.1(p), which shall solely be pursuant to the applicable Assignment). Except as expressly specified in this Agreement or any Associated Agreement and without limiting Partner’s right to indemnification under Section 12.2, Partner, on its own behalf and on behalf of the Partner Indemnified Parties, hereby releases, remises and forever discharges EP Energy and its Affiliates and all of such Persons’ equityholders, partners, members, directors, officers, employees, agents and representatives from any and all suits, legal or administrative proceedings, claims, demands, damages, losses, costs, Liabilities, interest or causes

of action whatsoever, at Law or in equity, known or unknown, which Partner or the Partner Indemnified Parties might now or subsequently have, based on, relating to or arising out of, any rights to contribution under CERCLA, as amended, breaches of statutory or implied warranties, nuisance or other tort actions, rights to punitive damages and common law rights of contribution, in each case, relating to any Environmental Condition or Liability under Environmental Law existing prior to the Execution Date.

Section 12.7 Indemnification Procedures. All claims for indemnification under Section 12.2 and Section 12.3 will be asserted and resolved as follows:

(a) For purposes of this Article XII, the term “Indemnifying Party” when used in connection with particular Liabilities means the Party or Parties having an obligation to indemnify the other Party or other Persons with respect to such Liabilities pursuant to this Article XII, and the term “Indemnified Party” when used in connection with particular Liabilities means the Party or other Persons having the right to be indemnified with respect to such Liabilities by the Indemnifying Party pursuant to this Article XII.

(b) To make a claim for indemnification under Section 12.2 or Section 12.3, an Indemnified Party will notify the Indemnifying Party of its claim under this Section 12.7, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a Third Party against the Indemnified Party (a “Third Party Claim”), the Indemnified Party will provide its Claim Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and will enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided, that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 12.7(b) will not relieve the Indemnifying Party of its obligations under Section 12.2 or Section 12.3 (as applicable) except to the extent (and then only to the extent) such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise materially prejudices the Indemnifying Party’s ability to defend against the Third Party Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice must specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(c) In the case of a claim for indemnification based upon a Third Party Claim, the Indemnifying Party will have 30 days from its receipt of the Claim Notice to notify the Indemnified Party whether it admits or denies its obligation to defend and indemnify the Indemnified Party against such Third Party Claim at the sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such 30 day period, to file any motion, answer or other pleading that it deems necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.

(d) If the Indemnifying Party admits its obligation to defend and indemnify the Indemnified Party against a Third Party Claim, it will have the right and obligation to diligently defend, at its sole cost and expense, the Indemnified Party against such Third

Party Claim. The Indemnifying Party will have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest; provided that the Indemnified Party shall not be required to bring any counterclaim or cross-complaint against any Person. The Indemnified Party may participate in, but not control, at its own expense, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 12.7(d). An Indemnifying Party will not, without the written consent of the Indemnified Party, (i) settle any Third Party Claim or consent to the entry of any judgment with respect thereto which does not include an unconditional written release of the Indemnified Party from all liability in respect of such Third Party Claim, or (ii) settle any Third Party Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity and paid by the Indemnifying Party).

(e) If the Indemnifying Party does not admit its obligation or admits its obligation to defend and indemnify the Indemnified Party against a Third Party Claim, but fails to diligently prosecute, indemnify against or settle the Third Party Claim, then the Indemnified Party will have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party’s choosing, subject to the right of the Indemnifying Party to admit its liability and assume the defense of the Third Party Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet admitted its obligation to defend and indemnify the Indemnified Party against a Third Party Claim, the Indemnified Party will send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party will have the option for 10 days following receipt of such notice to (i) admit in writing its liability to indemnify the Indemnified Party from and against the liability and consent to such settlement, (ii) if liability is so admitted, reject, in its reasonable judgment, the proposed settlement, or (iii) deny liability. Any failure by the Indemnifying Party to respond to such notice will be deemed to be an election under subsection (iii) above.

(f) In the case of a claim for indemnification not based upon a Third Party Claim, the Indemnifying Party will have 30 days from its receipt of the Claim Notice to (i) cure the Liabilities complained of, (ii) admit its liability for such Liability or (iii) dispute the claim for such Liabilities. If the Indemnifying Party does not notify the Indemnified Party within such 30 day period that it has cured the Liabilities or that it disputes the claim for such Liabilities, the amount of such Liabilities will conclusively be deemed a liability of the Indemnifying Party hereunder.

Section 12.8 Survival.

(a) Except for the Specified Representations, the representations and warranties of the Parties in Article XI with respect to (i) the First Tranche Drilling Program will survive the Execution Date for a period of 18 Calendar Months and (ii) the Second Tranche Drilling Program, if applicable, will survive for a period of 18 Calendar Months following the date

of approval of the Proposed Second Tranche Drilling Program. The Specified Representations (other than Section 11.1(f) and Section 11.1(o)) will survive the Execution Date without time limit and the representations and warranties in Section 11.1(f) and Section 11.1(o) will survive the Execution Date until the date that is 30 days following the expiration of the applicable statute of limitation. Subject to the foregoing and Section 12.8(b), the remainder of this Agreement will survive the Execution Date without time limit. Representations, warranties, covenants and agreements will be of no further force or effect after the date of their expiration; provided, that there will be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date.

(b) The indemnities in Section 12.2(a), Section 12.2(b), Section 12.3(a) and Section 12.3(b) will terminate as of the expiration date of each respective representation, warranty, covenant or agreement that is subject to indemnification, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Party on or before such expiration date; provided that, the indemnity in Section 12.2(b), as it relates to any covenant of EP Energy in Article IX, will survive the Execution Date until the date that is 30 days following the expiration of the applicable statute of limitation. EP Energy’s indemnities in Section 12.2(c) and Section 12.2(d) will terminate five Calendar Years after the expiration of the Availability Period. All remaining indemnity obligations contained in this Agreement will survive the execution hereof without time limit.

Section 12.9 Insurance. The amount of any Liabilities for which any of the Indemnified Parties is entitled to indemnification under this Agreement or in connection with or with respect to the transactions contemplated by this Agreement will be reduced by any corresponding insurance proceeds (less applicable insurance premiums) from insurance policies carried by a Party actually realized by such Party; provided that such Party will not be obligated to pursue such claims.

Section 12.10 Disclaimer of Application of Anti-Indemnity Statutes. The Parties acknowledge and agree that the provisions of any anti-indemnity statute relating to oilfield services and associated activities will not be applicable to this Agreement or the transactions contemplated hereby.

of it to issue, any press releases or otherwise make, or cause any agent or Affiliate of it to make, any public statements with respect to this Agreement, the Associated Agreements or the activities contemplated hereby or thereby, in each case except where such release or statement is (i) required by Law or under the rules and regulations of a recognized stock exchange on which shares of such Party or any of its Affiliates are listed (provided that such disclosures shall be made only to the extent required thereunder and in any case, prior to making any such press release or public statement, the releasing Party shall (if the urgency of the relevant Law or stock exchange rule so permits) provide a copy of the press release or public statement to the other Party), or (ii) limited to previously released publically available information, which press releases or statements will not be restricted by this Section 13.2.

(b) Notwithstanding anything to the contrary in Sections 13.1 or 13.2(a), in the event of any emergency which imminently and materially endangers property, lives or the environment, EP Energy may issue such press releases or public announcements as it deems reasonably necessary in light of the circumstances and will promptly provide Partner with a copy of any such press release or announcement, if commercially feasible, prior to such press releases or public announcements being released or made.

Partner will bear its own expenses (including fees, charges and disbursements of counsel for Partner) in connection with the preparation, negotiation, execution, delivery and performance of this Agreement and the other Associated Agreements including in connection with any amendments and the assessment of the Proposed Second Tranche Drilling Program (collectively, the “Partner Transaction Expenses”).

Section 14.2 Relationship of the Parties.

(a) The rights, duties, obligations and liabilities of the Parties (other than Affiliates) under this Agreement will be individual, not joint or collective.

This Agreement will not be deemed or construed to authorize any Party to act as an agent, servant or employee for the other Party for any purpose whatsoever except as explicitly set forth in this Agreement. In their relations with each other under this Agreement, the Parties will not be considered fiduciaries.

(b) Without being in derogation of the Parties’ intention that no partnership or joint venture shall exist between the Parties, in the event that, notwithstanding the intention of the Parties expressed in Section 14.2(a), a partnership or joint venture shall be deemed to exist, to the maximum extent permitted by applicable Law, each Party hereby waives any claim or cause of action against, and hereby eliminates all liabilities of, the other Party and

their respective Affiliates, employees, agents and representatives for any breach of any fiduciary duty by any such Person, including, as may result from a conflict of interest, any breach of loyalty or any breach of the duty of loyalty or care. Each Party acknowledges and agrees that in the event of any such conflict of interest, each Party may decide or act on any matter in its sole and absolute discretion taking into account solely its interests and those of its Affiliates, employees, agents and representatives.
