covenant in this Agreement. 
 Section 1.3. Excluded Assets. Notwithstanding anything to the contrary in
Article 1 or elsewhere in this Agreement, the “Shares” shall not include any rights with respect to any of the assets of the E&P Business set forth in Schedule 1.3 (the “Excluded Assets”) which, if

reasonably satisfactory to Purchaser, prior to the Closing, in each case at Sellers’ sole cost and expense (which instruments shall in any event provide that any such transfer or distribution shall be made without any representation or warranty
on an “AS IS WHERE IS” basis and the assignee thereunder assumes all obligations and liabilities with respect to the Excluded Assets). 
 Article 2 
 PURCHASE PRICE 

Section 2.1. Purchase Price. The purchase price for the Shares shall be $7,150,000,000 (the “Unadjusted
Purchase Price”), adjusted as provided in Section 2.3 (as so adjusted, the “Purchase Price”). 
 Section 2.2. Allocation of Purchase Price. 
 (a) The
Unadjusted Purchase Price shall be allocated as follows: (i) first, among the Shares of each of the Companies (such allocation, the “Share Unadjusted Purchase Price Allocation”) and (ii) thereafter, the portion of the
Unadjusted Purchase Price so allocated to the Shares of any Company (other than EP Egypt) shall be allocated among (A) the classes of assets of such Company and (B) with respect to EP Egypt and the BrazilCos, each of the exploration
and production concessions of such Company (such allocations, the “Asset Unadjusted Purchase Price Allocations”). If any adjustment is made to the Unadjusted Purchase Price pursuant to Section 2.3, then the Share
Unadjusted Purchase Price Allocation and the Asset Unadjusted Purchase Price Allocations shall each be revised to reflect such adjustment; provided that, in making any such revisions, proper account shall be given to the Company or the
specific asset to which such adjustment relates. 
 (b) Within sixty (60) days after the Closing Date, Sellers shall
prepare and deliver to Purchaser, using and based upon the best information available to Sellers, a schedule (the “Preliminary Section 2.2(b) Schedule”), along with reasonably detailed supporting documentation, setting forth
the following items: 
 (i) the Share Unadjusted Purchase Price Allocation and the Asset Unadjusted Purchase Price Allocations;


  
 29 









 (ii) the liabilities of each Company and the Wholly-Owned Subsidiaries as of the Closing
(as required for the allocations described in clause (iii) below), excluding any insurance liabilities insured by the Sellers’ captive insurance company; and 
 (iii) with respect to each Seller, an allocation among (A) the classes of assets of the Company or Companies to be sold by such Seller pursuant to this Agreement and (B) with respect to EP
Brazil, its exploration and production concessions, in each case, of the sum of (x) the portion of the Unadjusted Purchase Price allocated to the Shares to be sold by such Seller pursuant to this Agreement (as reflected in the Share Unadjusted
Purchase Price Allocation) and (y) the aggregate amount of liabilities described in the preceding clause (ii) that are includable in such Seller’s amount realized; provided that such allocation shall be consistent with the
Asset Unadjusted Purchase Price Allocations and shall be made in accordance with Section 1060 of the Code and the Treasury Regulations promulgated thereunder (and any similar provisions of state, local or foreign Law, as appropriate).

 Sellers shall at Purchaser’s request make reasonable documentation available to support the proposed allocation. As soon
as reasonably practicable, but not later than forty-five (45) days following receipt of Sellers’ proposed allocation schedule, Purchaser shall deliver to Sellers a written report containing any changes that Purchaser proposes to be made in
such schedule (and specifying the reasons therefor in reasonable detail). The Parties shall undertake to agree on a final schedule no later than fifteen (15) Business Days subsequent to the receipt by Sellers of Purchaser’s proposed
changes. 
 Within thirty (30) days after the later of the determination of the Purchase Price under
Section 2.4(b) and the agreement on the schedule described above in this Section 2.2(b), such schedule shall be amended by Sellers and delivered to Purchaser to reflect the Purchase Price following final adjustments.
Purchaser shall cooperate with Sellers in the preparation of the amended schedule in a manner consistent with the provisions of Section 8.4. If Sellers’ amendments to the schedule to reflect the Purchase Price following the final
adjustments are not objected to by Purchaser (by written notice to Sellers specifying the reasons therefor in reasonable detail) within thirty (30) days after delivery of Sellers’ adjustments to the schedule, it shall be deemed agreed upon
by the Parties and shall constitute the “Final Section 2.2(b) Schedule.” In the event that the Parties cannot reach an agreement within twenty (20) days after Sellers receive notice of any objection by Purchaser, then, any
Party may refer the matters in dispute to KPMG LLP or another mutually acceptable independent appraiser (the “Independent Appraiser”) to assist in determining the matters in dispute with respect to the allocation of the Purchase
Price. Should KPMG LLP fail or refuse to agree to serve as Independent Appraiser within twenty (20) days after written request from any Party to serve, and the Parties fail to agree in writing on a replacement Independent Appraiser within ten
(10) days after the end of that twenty (20) day period, or should no replacement Independent Appraiser agree to serve within forty-five (45) days after the original written request pursuant to this sentence, the Independent Appraiser
shall be appointed by the Houston, Texas office of the American Arbitration Association. In connection with the engagement of the Independent Appraiser, each of Sellers and Purchaser shall execute such engagement, indemnity and other agreements as
the Independent Appraiser shall require as a condition to such engagement. The Independent Appraiser shall be instructed to deliver to Purchaser and Sellers a written determination of the valuation and any revisions to the Preliminary
Section 2.2(b) Schedule within thirty (30) days after the date of referral thereof to the Independent Appraiser. Purchaser and Sellers agree to accept the Independent Appraiser’s determinations as to the matters in dispute and the
appropriate adjustments to the schedule to reflect those determinations, which as so adjusted shall constitute the Final Section 2.2(b) Schedule. The Independent Appraiser may determine the issues in dispute following such procedures and the
provisions of this Agreement, as it reasonably deems appropriate in the circumstances and with reference to the amounts in 

  
 30 









 
issue. The Parties do not intend to impose any particular procedures upon the Independent Appraiser, it being the desire and direction of the Parties that any such disagreement shall be resolved
as expeditiously and inexpensively as reasonably practicable. The Independent Appraiser shall act as an expert for the limited purpose of determining the specific disputed aspects of the allocation schedule submitted by any Party and may not award
damages, interest, or penalties to any Party with respect to any matter. Each Seller and Purchaser shall bear its own legal fees and costs of presenting its case. Sellers shall bear one half and Purchaser shall bear one half of the costs and
expenses of the Independent Appraiser. 
 The allocations set forth in the Final Section 2.2(b) Schedule shall be used by
Sellers, Purchaser and the Companies and Wholly-Owned Subsidiaries as the basis for reporting asset values and other items for purposes of all Tax Returns. The allocations set forth in the Final Section 2.2(b) Schedule shall also be used by
Sellers and Purchaser in preparing IRS Form 8594, Asset Acquisition Statement, and other required forms. Such Form 8594 shall be completed by such Parties as soon as practicable after the Closing but in no event later than fifteen (15) days
prior to the date such form is required to be filed. Sellers and Purchaser agree not to assert, and will cause their Affiliates not to assert, in connection with any audit or other proceeding with respect to Taxes, any asset values or other items
inconsistent with the amounts set forth in the Final Section 2.2(b) Schedule unless otherwise required by a determination under Section 1313(a) of the Code. 
 Section 2.3. Adjustments to Purchase Price. The Unadjusted Purchase Price shall be adjusted as of the Closing pursuant to Section 2.4(a) and, after the Closing, pursuant to
Section 2.4(b), but only with respect to matters identified in the Closing Settlement Statement, the Post-Closing Statement or an Adjustment Notice, in accordance with the following: 

(a) (i) decreased by the amount of cash or cash equivalents of the Companies or any of their Wholly-Owned Subsidiaries distributed from
and after the Effective Time until Closing to any Seller or any of its Affiliates (other than the Companies and their Wholly-Owned Subsidiaries) or (ii) increased by the amount of any cash or cash equivalents contributed to the Companies or the
Wholly-Owned Subsidiaries (including intercompany debt of a Company or a Wholly-Owned Subsidiary that is capitalized in accordance with Section 5.7) from and after the Effective Time until Closing by any Seller or any Person who,
directly or indirectly, owns an equity interest in any Seller; 
 (b) decreased by the amount (if the Effective Time Net
Working Capital is negative, the absolute value) of the Effective Time Net Working Capital; 
 (c) decreased by the principal
amount of all Indebtedness (for this purpose, ignoring clause (v) of the definition thereof) owing by the Companies and any Wholly-Owned Subsidiary to any Person other than a Company or a Wholly-Owned Subsidiary of any Company
(“Loans”) at the Effective Time and all interest that has accrued and that accrues through the Closing Date on the principal amount of such Loans outstanding as of the Effective Time and all prepayment penalties, premiums, fees and
other similar costs and expenses due and owing in connection with the repayment of Loans in accordance with the Debt Payoff Letters; 
 (d) increased by any amounts (other than in respect of Taxes) paid by any Seller (or any Person who, directly or indirectly, owns an equity interest in any Seller) on behalf of any of the Companies or any
of their Subsidiaries, including the Wholly-Owned Subsidiaries, from and after the Effective Time and prior to Closing, including any payments by any such Person to satisfy Loans or other obligations pursuant to Section 5.7,
Section 5.8 or Section 5.9 (other than, in any such case, any amounts that, based on historical practice, are included in the applicable corporate allocation of shared services from any Affiliate of any Seller to any Seller);


  
 31 









 (e) increased or decreased, as appropriate, in accordance with Section 1.5 of
Annex 1; 
 (f) increased by the amount of interest accrued on the Unadjusted Purchase Price from the Effective
Time until the Closing Date at a rate of interest equal to the Agreed Rate; provided, that interest on that portion of the Unadjusted Purchase Price that is equal to the (i) portion of the bond offering component of the Debt Financing
that is funded into escrow (in the event proceeds therefrom are deposited into escrow) shall only accrue from the Effective Time until the later of (x) the Bond Escrow Date applicable to the portion so funded and (y) the date that is
ninety (90) calendar days after the Execution Date and (ii) bank lending component of the Debt Financing shall only accrue from the Effective Time until the later of (x) the Bank Execution Date and (y) the date that is ninety
(90) calendar days after the Execution Date, at a rate of interest equal to the Agreed Rate; 
 (g) decreased by all
amounts incurred by or (to the extent such amounts are subject to Section 2.3(d)) on behalf of any Company or any Company Subsidiary (net to Sellers’ indirect interest) (including (to the extent such amounts are subject to
Section 2.3(d)) all amounts incurred by Sellers or any of their Affiliates) after the Effective Time until Closing in connection with curing or attempting to cure (i) any Title Defect or (ii) any breach of any representation or
warranty set forth in Article 3 whether or not such breach of representation or warranty is claimed by Purchaser, but: 

(A) in the case of clause (i) with respect to amounts incurred to cure or attempt to cure any Title Defect, decreased only to the
extent the Unadjusted Purchase Price would have been decreased pursuant to Section 2.3(e) if such Title Defect had not been cured (and, if the amounts incurred to cure and attempt to cure such Title Defect with respect to any Title Asset
are not applied to reduce the Unadjusted Purchase Price pursuant to this Section 2.3(g), then the aggregate of (x) such amounts plus (y) the portion of the Title Defect Amount associated with the uncured portion of the
Title Defect pertaining to such Title Asset and asserted by Purchaser in accordance with Annex 1 shall (if such aggregate amount of clauses (x) and (y) exceeds the Title Threshold) be applied dollar for dollar to reduce the Title
Deductible); provided, however, that costs incurred by (or on behalf of) any Company or Company Subsidiary to cure or to attempt to cure any Title Defect after the Title Claim Date shall not be subject to the foregoing provisions of
this Section 2.3(g) (and, for the avoidance of doubt, such costs shall not be applied to reduce the Unadjusted Purchase Price) unless Purchaser has delivered a Title Defect Notice with respect to such Title Defect prior to the expiration
of the Title Claim Date; and 
 (B) in the case of clause (ii) with respect to any breach of any such representation or
warranty, decreased only to the extent Sellers would owe an indemnification payment under Article 10 if the representation and warranty had not been cured (after taking into account the limitations on indemnification under Sections
10.1(d)(iv) and 10.4(c)) and assuming Purchaser had timely asserted a claim for indemnification under Article 10) (and to the extent the amounts incurred to cure and attempt to cure any such breach of any such representation or
warranty are not applied to reduce the Unadjusted Purchase Price pursuant to this Section 2.3(g) as a result of the application of the limitations on indemnification under Section 10.4(c), then such amounts shall be applied
to reduce on a dollar for dollar basis the two percent (2%) deductible referred to in Section 10.4(c); and 

(h) decreased by an amount equal to the Allocated Value of each Company Property set forth on Exhibit C-1 to Annex 1
that is sold (or otherwise disposed of) by any Company or Company Subsidiary (or any of their Affiliates) prior to the Effective time (and, where only a portion of any such Company Property is so sold or disposed of, decreased by the portion of such
Allocated Value attributable to such portion so sold or otherwise disposed of). 

  
 32 









 In calculating the adjustment to the Unadjusted Purchase Price pursuant to this
Section 2.3, no adjustment may be accounted for in more than one of the paragraphs (a) through (h) above. For clarity, (i) no payment by any Company or Wholly-Owned Subsidiary pursuant to Section 5.7 shall be
deemed to have been distributed to any Seller or its Affiliates for purposes of Section 2.3(a), (ii) no payment by any Seller or its Affiliates (other than the Companies and Wholly-Owned Subsidiaries) pursuant to
Section 5.7 shall be deemed to have been contributed to the Companies or the Wholly-Owned Subsidiaries for purposes of Section 2.3(a), (iii) any Loan amount that is capitalized in accordance with Section 5.7
shall be deemed to have been contributed to the Companies or the Wholly-Owned Subsidiaries for purposes of Section 2.3(a), (iv) no payment received or made in respect of any ordinary course sale of goods or services, respectively,
by any Seller or its Affiliates (other than the Companies and Wholly-Owned Subsidiaries), on the one hand, from or to, respectively, any Company or Wholly-Owned Subsidiary, on the other hand, shall adjust the Unadjusted Purchase Price pursuant to
this Section 2.3 and (v) distributions to any Seller or its Affiliates in respect of amounts that would be owed to Sellers pursuant to Section 8.7 if such amounts were received after the Closing shall not adjust the
Unadjusted Purchase Price pursuant to this Section 2.3. For the avoidance of doubt, the Parties acknowledge and agree that no adjustments shall be made to the Effective Time Net Working Capital. 

Notwithstanding anything to the contrary contained herein, there shall be no adjustments made (i) pursuant to
Section 2.3(c) with respect to any of the obligations described in item 2 of Schedule 3.5 or (ii) pursuant to any provision of this Section 2.3 with respect to any actions taken between the Execution Date and the
Closing with respect to such obligations pursuant to Section 5.7 or Section 8.10(a) or as described in Schedule 3.5. 
 Section 2.4. Closing Payment and Post-Closing Purchase Price Adjustments. 
 (a) Not later than five (5) Business Days prior to the Closing Date, Sellers shall prepare and deliver to Purchaser a settlement statement (the “Closing Settlement Statement”)
calculating the amount equal to the Unadjusted Purchase Price as adjusted to give effect to Sellers’ good faith estimate of the adjustments provided for in Section 2.3 (or, if then determinable, the final amounts thereof). Purchaser
shall have three (3) Business Days to review the settlement statement from Purchaser’s receipt thereof. On the day following expiration of such three (3) Business Day review period, Purchaser shall submit a written report containing
any changes Purchaser proposes to be made to the settlement statement. Sellers and Purchaser shall agree on a final settlement statement no later than one (1) Business Day prior to Closing; provided, however, if Sellers and
Purchaser are unable to agree, then, subject to Section 2.4(b), Sellers’ determination shall be used for purposes of the payment to be made at the Closing. The calculation delivered by Sellers in accordance with this
Section 2.4(a), as adjusted in accordance with the immediately preceding sentence, if applicable, shall constitute the dollar amount to be paid by Purchaser to Sellers at the Closing (the “Closing Payment”). 

(b) As soon as reasonably practicable after the Closing but not later than the later of the ninetieth (90th) day following the
Closing Date and the day on which all Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts (but not, for the avoidance of doubt, any Required Consent Dispute) have been finally determined in accordance with
Section 1.5(i) of Annex 1, Purchaser shall prepare and deliver to Sellers a draft statement (the “Post-Closing Statement”) setting forth the final calculation of the Purchase Price taking into account any adjustments
pursuant to Section 2.3 (and any Title Defects finally resolved pursuant to Section 1.5 of Annex 1 after the Closing). As soon as reasonably practicable but not later than the sixtieth (60th) Business Day following
receipt of Purchaser’s statement hereunder, Seller shall deliver to Purchaser a written report (an “Adjustment Notice”) containing any changes (other than with respect to Title Defects) Sellers propose be made in such
statement. Sellers shall be deemed to have accepted and agreed to all items in the Post-Closing Statement other than such matters that are proposed to be changed in the Adjustment Notice and other than Title Defects. The Parties shall undertake to
agree on the final Purchase Price no later than ten (10) Business Days after delivery of the Post-Closing Statement. If the final Purchase Price is: 
 (i) mutually agreed upon in writing by Sellers and Purchaser during such ten (10) Business Day period, the final Purchase Price shall be conclusive and binding on the Parties; or 

  
 33 









 (ii) not mutually agreed upon by Sellers and Purchaser during such ten (10) Business
Day period, then KPMG LLP (the “Dispute Auditor”) shall resolve any disagreements (other than with respect to Title Defects). Should KPMG LLP fail or refuse to agree to serve as Dispute Auditor within ten (10) days after
written request from any Party to serve, and the Parties fail to agree in writing on a replacement Dispute Auditor within five (5) days after the end of that ten (10) day period, or should no replacement Dispute Auditor agree to serve
within fifteen (15) days after the original written request pursuant to this sentence, the Dispute Auditor shall be appointed by the Houston, Texas office of the American Arbitration Association. In connection with the engagement of the Dispute
Auditor, each of Sellers and Purchaser shall execute such engagement, indemnity and other agreements as the Dispute Auditor shall require as a condition to such engagement. The Dispute Auditor shall determine as promptly as practicable, but in any
event within thirty (30) days after the selection of the Dispute Auditor, based solely on written submissions provided by Purchaser and Sellers to the Dispute Auditor (and without independent investigation on the part of the Dispute Auditor)
within ten (10) days following the Dispute Auditor’s selection, whether and to what extent (if any) Purchaser’s statement requires adjustment. In resolving any disputed item, the Dispute Auditor shall act as an expert and not an
arbitrator, and shall resolve only the items set forth in the Adjustment Notice that are still in dispute and may not assign a value to any item greater than the highest value for such item claimed by either Party or less than the lowest value for
such item claimed by either Party. The fees and expenses of the Dispute Auditor shall be paid by the Parties in inverse proportion to the relative success of their claims. The determination of the Dispute Auditor shall be final, conclusive and
binding on Purchaser and Sellers. The date on which the final Purchase Price is finally determined in accordance with this Section 2.4(b) is referred to as the “Determination Date.” 

(c) Any difference in the Closing Payment and the final Purchase Price shall be paid by the owing Party to the owed Party within ten
(10) Business Days of the Determination Date. Any post-Closing payment pursuant to this Section 2.4 shall bear interest from the Closing Date to the date of payment at the Agreed Rate. 

(d) Sellers shall assist Purchaser in preparation of the Post-Closing Statement of the Purchase Price under Section 2.4(b)
by furnishing invoices, receipts, reasonable access to personnel and such other assistance as may be requested by Purchaser to facilitate such process post-Closing. 
 (e) All payments made or to be made under this Agreement to Sellers shall be made by electronic transfer of immediately available funds to New EPE, acting as representative of Sellers, at the account set
forth in Schedule 2.4(e), for the credit of the applicable Sellers, or to such other bank and account as may be specified by New EPE in writing. All payments made or to be made hereunder to Purchaser shall be by electronic transfer or
immediately available funds to a bank and account specified by Purchaser in writing to New EPE, for the credit of Purchaser. 

Section 2.5. Withholding Rights. Purchaser shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement such amounts as Purchaser is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax Laws. To the extent that such amounts are so
withheld by Purchaser, such withheld and deducted amounts will be treated for all purposes of this Agreement as having been paid to the holders of the Shares in respect of which such deduction and withholding was made by Purchaser.

Schedule 3.20 that are listed as current are in full force and effect in all material respects and satisfy all requirements of applicable Laws and, other than as have not had or would not have, individually or in the aggregate, a Material

Property in any material respect, other than with respect to any geophysical or seismic licenses. 
 Section 3.22.
Oil and Gas Matters. 
 (a) Company Properties. Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect, all proceeds from the sale of Hydrocarbons produced from Company Properties are being received by a Company or Company Subsidiary in a timely manner and are not being held in suspense.

 (b) Major Midstream Assets. Subject to the RE Permitted Encumbrances, the Companies and the Company Subsidiaries have
good and defensible title to the Rights of Way and other real property interests used in their ownership and/or operation of the Holly Gathering System (as owned and/or operated as of the Execution Date) (the “Major Midstream
Assets”), except for such failures to have good and defensible title to the Rights of Way and other real property interests used in such ownership and/or operation of the Holly Gathering System that would not be materially adverse to the
value, ownership, use, or operation of the Major Midstream Assets. The Major Midstream Assets are located within or on property covered by such Rights of Way or other real property interests, except with respect to those instances in which the
failure of such Major Midstream Assets to be located within or on such property would not be materially adverse to the value, ownership, use or operation of the applicable Major Midstream Asset. The Rights of Way and other real property interests
used in the ownership and/or operation of the Major Midstream Assets as owned and/or operated as of the Execution Date constitute continuous land rights, except for gaps which would not be materially adverse to the value, ownership, use or operation

Material Adverse Effect.

operated by any Company or Company Subsidiary, or to Sellers’ knowledge with respect to any Company Mineral Interests operated by any third party, as of November 1, 2011, except as set forth in Schedule 3.22(d) or except as would
not exceed $100,000 on a well by well basis. There are no pipeline, transportation or processing imbalances existing with respect to the Company Mineral Interests as of November 1, 2011 that exceed $100,000, except as set forth on Schedule
3.22(d). In making this representation and warranty with respect to Company Properties operated by third Persons, Sellers shall be entitled to rely upon imbalance statements rendered by such operators as of November 1, 2011. 

(e) Production. Other than gas balancing obligations, no Company or Company Subsidiary is obligated by virtue of a take or pay
payment, advance payment or other similar payment (other than royalties and similar arrangements established in the Company Mineral Interests) to deliver Hydrocarbons, or proceeds from the sale thereof, attributable to any Company’s or Company
Subsidiary’s interest in the Company Properties at some future time without receiving payment therefor at or after the time of delivery. 
 (f) Brazil Concessions. One or more of the BrazilCos own (directly or indirectly) the interests set forth on Schedule 3.22(f) in each Brazil Concession. Schedule 3.22(f) lists all
exploration and production concessions granted by ANP for the exploration and production of Hydrocarbons in which any Company or Company Subsidiary holds a participating interest (directly or indirectly). None of Sellers, the Companies or the
Company Subsidiaries have received any written notice or, to any Seller’s knowledge, oral notice, from any Governmental Authority or any other Person regarding any actual, alleged, possible or potential material violation, material breach or
default of, or material failure to comply with, any of the Contracts creating the applicable Company’s or Company Subsidiary’s right, title and interest in and to the Brazil Concessions (such Contracts, the “Brazil Concession
Contracts”). The applicable Seller, Company or Company Subsidiary party to (or guarantor with respect to) the Brazil Concession Contracts has performed all material obligations under each Brazil Concession Contract. All of the Brazil
Concession Contracts are valid and binding upon the applicable Company or Company Subsidiary party thereto or subject thereto and, to Seller’s knowledge, in full force and effect and enforceable, in each case, in all material respects, against
the other parties thereto. No event has occurred with respect to any Brazil Concession Contract that, after notice or lapse of time, or both, would constitute a material default by any Seller, Company or Company Subsidiary party thereto or subject
thereto or, to any Seller’s knowledge, any other party thereto. True, complete and correct copies of the Brazil Concession Contracts in existence as of the execution hereof have been included in the Data Room. No notice of default or breach has
been delivered by any Seller, Company or Company Subsidiary under any Brazil Concession Contract, the resolution of which is currently outstanding. 
 Section 3.23. Royalties. All rentals, delay rentals, shut-ins, royalties and other payments due under the Company Mineral Interests operated by any Company or Company Subsidiary, and to
Sellers’ knowledge, all rentals, delay rentals, shut-ins, royalties and other payments due under the Company Mineral Interests operated by any third party, have been promptly and fully paid, except (a) to the extent such failure has not
had and would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect and (b) for amounts that are being held in suspense. 
 Section 3.24. Qualification. The Companies and the Company Subsidiaries that own Company Mineral Interests, rights of way and other rights issued by the United States government or


  
 47 









 
other Governmental Authorities are qualified under applicable Laws to hold such Company Mineral Interests, rights of way and other rights, except for such non-compliance as may result from the
actions contemplated by Section 8.10 and which non-compliance is cured on or before Closing. 
 Section 3.25.
Affiliate Transactions. Except as set forth on Schedule 3.25, there are no Contracts or arrangements relating to transactions (other than related to continuing employment and benefit matters) between any Company or any Company
Subsidiary, on the one hand, and any Seller, equity holder, manager or executive officer thereof or any member of such executive officer’s, director’s or stockholder’s immediate family, or any Affiliate or Person controlled by such

 Section 4.7. Financing. 

(a) Purchaser has delivered to Sellers correct and complete copies of: 

(i) executed commitment letters dated as of the date hereof (including all exhibits, schedules and annexes thereto, collectively, the
“Equity Funding Letters”) from the parties set forth therein (collectively, the “Equity Providers”) pursuant to which the Equity Providers have committed, subject to the terms and conditions therein, to invest the
amounts set forth therein (the “Equity Financing”); and 
 (ii) an executed commitment letter dated as of the
date hereof (as the same may be amended or replaced pursuant to Section 5.19(a) and including any executed commitment letter (or similar agreement) for Alternate Financing, in each case, pursuant to Section 5.19(c), including
all exhibits, schedules and annexes thereto, collectively, the “Debt Commitment Letter” and, together with the Equity Funding Letters, the “Financing Letters”) from the financial institutions identified therein

forth therein (collectively, the “Debt Financing,” and together with the Equity Financing collectively referred to as the “Financing”). 
 (b) As of the date hereof, none of the Financing Letters have been amended or modified in any respect, and the respective obligations and commitments contained in such letters have not been withdrawn or
rescinded in any respect. Purchaser has fully paid or has caused to be fully paid any and all commitment fees or other fees in connection with the Financing Letters that are 

  
 52 









 
payable on or prior to the date hereof. Assuming (i) the Financing is funded in accordance with the Financing Letters, (ii) the accuracy of the representations and warranties set forth
in Article 3 and (iii) the performance by Sellers and the Companies of the covenants contained in this Agreement, the net cash proceeds contemplated by the Financing Letters will, together with available cash of Purchaser and cash on
hand of the Companies, if any, on the Closing Date, in the aggregate be sufficient for Purchaser to pay the following (the “Required Amount”): the aggregate amounts required to be paid by Purchaser pursuant to
Section 2.1, and all fees, costs and expenses required to be paid by Purchaser in connection with the transactions contemplated by this Agreement and by the Financing. 

(c) The Financing Letters are in full force and effect and are the valid, binding and enforceable obligations of Purchaser and, to the
knowledge of Purchaser, the other parties thereto, except as such enforceability may be (i) limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws of general application relating to or
affecting creditors’ rights generally and (ii) subject to general equitable principles (whether considered in a proceeding in equity or at law). Assuming the accuracy of the representations and warranties set forth in Article 3 and
the performance by Sellers, the Companies and the Company Subsidiaries of their obligations contained in this Agreement as of the date of this Agreement, no event has occurred which, with or without notice, lapse of time or both, would or would
reasonably be expected to constitute a default or breach on the part of Purchaser or, to the knowledge of Purchaser, any other parties thereto, under the Financing Letters. As of the date of this Agreement, Purchaser is not aware of any fact,
occurrence or condition that makes any of the assumptions or statements set forth in the Financing Letters inaccurate in any material respect or that would cause any of the commitments provided in the Financing Letters to be terminated or
ineffective or, assuming satisfaction of the condition precedent set forth in Section 6.2(a), any reason to believe that any of the conditions precedent set forth therein will not be met. The Financing Letters contain all of the
conditions precedent to the obligations of the parties thereunder to make the Financing available to Purchaser on the terms therein, and there are no other conditions related to the funding of the full amount of the Financing. As of the date hereof,
there are no side letters or other contracts, arrangements or understandings to which Purchaser or any of its Subsidiaries or the Equity Providers are a party related to the funding or investing, as applicable, of the full amount of the Financing
(other than the Financing Letters), except for any customary fee, fee credit and engagement letters in respect of the Debt Financing (in each case, which shall not reduce, or contemplate the reduction of, the full amount of the Debt Financing below
the amount of the Required Amount, after taking into account other sources of funds, including the Equity Financing and available cash of Purchaser). 
 (d) In no event shall the receipt or availability of any Financing by Purchaser or any of its Affiliates be a condition to any of Purchaser’s obligations hereunder.

sale or distribution in violation of the Securities Act of 1933, as amended, the rules and regulations thereunder, any applicable state blue sky Laws, or any other applicable securities Laws. 

Section 4.9. Independent Investigation. Purchaser is (or its advisors are) experienced and knowledgeable in the oil
and gas business and aware of the risks of that business. Except for the representations and warranties expressly made by Sellers in Article 3, in the certificate to be delivered to Purchaser pursuant to Section 7.2(b), in any
other agreement or document delivered pursuant to this Agreement or in any certificate delivered by Sellers pursuant to Section 1.2(c)(v) of Annex 1, Purchaser acknowledges that there are no representations or warranties, express or
implied, as to the financial condition, assets, liabilities, equity, operations, business or prospects of the Companies, the Wholly-Owned Subsidiaries or any Affiliate thereof, and that in making its decision to enter into this Agreement and to
consummate the transactions contemplated hereby, Purchaser has relied solely upon the 

  
 53 









 
representations and warranties expressly made in Article 3, in the certificate to be delivered to Purchaser pursuant to Section 7.2(b), in any other agreement or document
delivered pursuant to this Agreement or in any certificate delivered by Sellers pursuant to Section 1.2(c)(v) of Annex 1, its own independent investigation, verification, analysis and evaluation. 

Section 4.10. Liability for Brokers’ Fees. Sellers, and, prior to Closing, the Companies, shall not directly or
indirectly have any responsibility, liability or expense, as a result of undertakings or agreements of Purchaser, for brokerage fees, finder’s fees, agent’s commissions or other similar forms of compensation to an intermediary in

Article 5 

COVENANTS OF THE PARTIES 
 Section 5.1. Access. 
 (a) On and after the Execution Date to
the Closing Date, Sellers will give Purchaser and its representatives reasonable access to the E&P Business (and to personnel and representatives of Sellers, Companies, the Company Subsidiaries and their respective Affiliates responsible for the
E&P Business at such times as Purchaser may reasonably request) and reasonable access to and the right to copy, at Purchaser’s expense, the Company Records in Sellers’, the Companies’, the Company Subsidiaries’ and/or their
respective Affiliates’ possession or readily available to any of them at immaterial cost or expense, for the purpose of conducting a due diligence review of the E&P Business, the Companies and the Company Subsidiaries and for transition and
integration planning. Such reasonable access by Purchaser shall be limited to Sellers’ normal business hours, and Purchaser’s investigation shall be conducted in a manner that does not unreasonably interfere with the operation of the
E&P Business or the other businesses of Sellers or their Affiliates. Purchaser’s right of access shall not entitle Purchaser to operate Company Equipment to conduct intrusive or environmental testing or sampling, and prior to the Closing
Purchaser shall not operate Company Equipment or conduct intrusive or environmental testing or sampling. Purchaser shall provide Sellers with prior notice before the E&P Business is accessed pursuant to this Section 5.1, along with a
description of the activities Purchaser intends to undertake. All information obtained by Purchaser and its representatives under this Section 5.1 shall be subject to the terms of that certain confidentiality agreement between El Paso
and an Affiliate of Purchaser, dated as of November 3, 2011 (the “Confidentiality Agreement”), and any applicable privacy Laws regarding personal information. 

(b) Section 5.1(a) shall not require Sellers to permit any access, or to disclose any information, that in the reasonable,
good faith judgment (after consultation with outside counsel) would reasonably be expected to result in violation of any Contract to which any Seller or any of Sellers’ Affiliates is a party or applicable Laws, including the Antitrust Laws, or

or what any such Seller’s or such Seller’s Affiliates’ believes in good faith (after consultation with counsel) could be, future litigation; provided, however, that the Parties shall cooperate in seeking to find a way to
allow disclosure of such information to the extent doing so would not reasonably be likely (in the good faith belief of the Party (or its Affiliate) disclosing such information) to result in the violation of any such Contract or Law or reasonably be
likely to cause such privilege to be undermined with respect to such information or could reasonably (in the good faith belief of the Party (or its Affiliate) disclosing such information) be managed through the use of customary

contemplated by this Agreement under the Antitrust Laws. The Parties shall, and shall cause their respective Affiliates to use their reasonable best efforts to, provide each other with copies of
all material, substantive correspondence, filings or communications between them or any of their respective representatives, on the one hand, and any Governmental Authority or members of its staff, on the other hand, with respect to this Agreement
and the transactions contemplated by this Agreement; provided, however, that materials may be redacted (i) to remove references concerning the valuation of the Companies; (ii) as necessary to comply with contractual
arrangements or applicable Laws and (iii) as necessary to address reasonable attorney-client or other privilege or confidentiality concerns. 
 (c) Purchaser shall, and shall cause each of its Affiliates to, use their reasonable best efforts to take any and all steps necessary to avoid or eliminate each and every legal impediment under any
applicable Antitrust Law that may be asserted by any antitrust or competition Governmental Authority or any other Party so as to enable the Parties hereto to close the transactions contemplated by this Agreement as promptly as practicable, and in

defend through litigation on the merits any claim asserted in court or administrative or other tribunal by any Person (including any Governmental Authority) in order to avoid entry of, or to have vacated or terminated, any decree, Order or judgment
(whether temporary, preliminary or permanent) that would prevent the Closing prior to the End Date; provided, however, that such litigation in no way limits the obligations of the Parties to comply with their reasonable best efforts

Purchaser with respect thereto; provided, however, that Purchaser shall consult in advance with Sellers and in good faith take Sellers’ views into account regarding the overall strategic direction of the defense of any such
litigation and consult with Sellers prior to taking any material substantive positions, making dispositive motions or other material substantive filings or entering into any negotiations concerning such litigation. 

(d) Purchaser shall, to the extent practicable and permitted by the relevant Governmental Authority, give Sellers (through their
counsel) the opportunity to attend and participate in all substantive meetings, telephone calls or discussions in respect of any filings, investigation (including settlement of the investigation), litigation or other inquiry.

and Wholly-Owned Subsidiaries) shall (i) either capitalize or cause each Company and Wholly-Owned Subsidiary to repay by cash payment any Loans of such Company or Wholly-Owned Subsidiary from Sellers or any other Affiliates and (ii) repay
any loans (together with all accrued and unpaid interest thereon) of Sellers or any such Affiliate from any Company or Wholly-Owned Subsidiary. Notwithstanding the foregoing, with respect to any such loan outstanding between (x) EP Brazil and
Brazil O&G, (y) EP Brazil and El Paso Maritime BV or (z) EP Brazil and UnoPaso (as such Loans are further described in Schedule 3.5) (collectively, the “Foreign Loans”), upon Purchaser providing written notice
to Sellers (such notice to be provided no later than thirty (30) days before the Closing Date), Sellers and their Affiliates (other than the Companies and Wholly-Owned Subsidiaries) shall capitalize all or a portion of such Foreign Loans to the
equity of the relevant obligor, as stipulated in such written notice. To the extent all or a portion of such Foreign Loans are not capitalized pursuant to the preceding sentence Purchaser shall purchase the non-capitalized portion of such Foreign
Loans from EP 

  
 62 









 
Brazil for an amount equal to the principal amount of each Foreign Loan as of the Closing. Nothing to the contrary in this Agreement withstanding, the purchase or capitalization of the Foreign
Loans pursuant to this Section 5.7 will have no impact on the Unadjusted Purchase Price and will not result in any adjustments pursuant to Section 2.3; however, to the extent the Foreign Loans are purchased by Purchaser a
portion of the Purchase Price equal to the amount paid for such Foreign Loans will be allocated to the Foreign Loans pursuant to Section 2.2(b).

 (a) Sellers shall
use commercially reasonable efforts to deliver a draft Debt Payoff Letter from each payee of a Third-Party Loan to the applicable payor Company or Wholly-Owned Subsidiary at least two (2), but no more than five (5), Business Days prior to the
Closing Date, copies of which shall be promptly delivered to Purchaser. 
 (b) At or prior to Closing, except as set forth in
Schedule 5.8(b), Sellers shall have paid or caused the Companies and Wholly-Owned Subsidiaries to pay all amounts payable as set forth in any applicable Debt Payoff Letter. Purchaser, each Seller and each Company shall cooperate in arranging
for such Lien releases as of Closing. 
 Section 5.9. Hedges. 

(a) As soon as reasonably practicable after the Execution Date and in consultation with Purchaser, Sellers shall cause the Companies and
Wholly-Owned Subsidiaries to enter into new swaps so that the commodity price risk associated with the anticipated future production of the Companies and Wholly Owned Subsidiaries set forth on Schedule 5.9 for the calendar years of 2012 and
2013 will be hedged at market prices prevailing at the time of entering into such swaps. Sellers shall consult with Purchaser concerning the counterparties to such hedges and the quantities to be hedged. As such hedges are entered into, Sellers
shall promptly notify Purchaser of the counterparty to the transaction, the product involved, the quantity hedged, the hedge price under the new hedge, any premiums or other payments made or received to enter into any new hedge and all other details
of the transaction and provide Purchaser copies of the confirmations and other documentation evidencing such transactions. Purchaser may request that Sellers enter into new swaps so that the commodity price risk associated with the anticipated
future production of the Companies and the Wholly Owned Subsidiaries for calendar year 2012 or 2013 will be hedged to a greater percentage level than the levels set forth on Schedule 5.9, or that commodity price risk associated with the
anticipated future production of the Companies and the Wholly Owned Subsidiaries for calendar years 2014 and 2015 will be hedged at specified percentage levels (the “Requested Swaps”). Sellers shall (and shall cause the Companies
and Company Subsidiaries to) reasonably cooperate with Purchaser to accommodate such request and implement the Requested Swaps, as permitted under the Revolving Credit Facility. Notwithstanding anything to the contrary herein, in no event shall
Sellers, the Companies and the Company Subsidiaries be required to (i) enter into any transaction relating to Derivatives that would constitute a breach of, or default under, the Revolving Credit Facility or the EP Revolver or (ii) enter
into any transactions relating to Requested Swaps unless Purchaser has agreed to pay and/or post (and does pay and/or post) any required premium, fee or other cost or expense associated with, or collateral required by, such transaction prior to its
consummation. 
 (b) If this Agreement is terminated pursuant to Article 9, Sellers shall have the right to terminate
any Requested Swaps by giving Purchaser written notice thereof on or before ten (10) Business Days after such termination. To the extent Sellers elect to terminate a Requested Swap, Purchaser shall indemnify, defend and hold harmless Sellers
and their Affiliates (including, until termination of this Agreement, the Companies and Company Subsidiaries) from and against any and all 

  
 63 









 
direct fees, losses and expenses resulting from actions taken by such Persons at Purchaser’s request with respect to such terminated Requested Swap. To the extent Sellers do not elect to
terminate such Requested Swap, Sellers shall promptly refund any required premium, fee or other cost or expense paid by or on behalf of Purchaser with respect to the applicable terminated Requested Swap. 

Section 5.10. Further Assurances. After Closing, each of Sellers and Purchaser agree to take such further actions and
to execute, acknowledge and deliver all such further documents as are reasonably requested by the other for carrying out the purposes of this Agreement or of any document delivered pursuant to this Agreement. 

Section 5.11. Employee Matters. 
 (a) Prior to Closing, Sellers and their Affiliates shall cause each of the Business Employees to be employed by either EP E&P Management, Brazil O&G or Egypt Production, subject to exceptions due
only to terminations and resignations, in each case, in the ordinary course, consistent with Sellers’ and their Affiliates’ past employment practices. 
 (b) Schedule 5.11(b), which is subject to changes due only to hirings, terminations and resignations, in each case, in the ordinary course, consistent with the Companies’ and the Company
Subsidiaries’ past employment practices, lists, as of the Execution Date, the Business Employees by reference to their employee identification number and job category, Sellers acknowledging and agreeing that contemporaneously with the execution
of this Agreement, Sellers have provided a corresponding list of the names of such Business Employees and their date of hire, rate of base salary or hourly wage, annual bonus, active employee status and job description, which will not be listed on
Schedule 5.11(b). At Closing, Sellers shall deliver to Purchaser a revised Schedule 5.11(b) that lists the Business Employees and the information in the preceding sentence with respect to each such employee as of ten (10) days
prior to the Closing (Sellers acknowledging and agreeing that contemporaneously with the delivery of the revised Schedule 5.11(b), Sellers shall provide a corresponding list of the names of such Business Employees and their dates of hire,
rate of base salary or hourly wage, annual bonus, active employee status and job description, which will not be listed on Schedule 5.11(b)), provided, that, any revisions to Schedule 5.11(b) shall be due only to hirings,
terminations and resignations, in each case in the ordinary course, consistent with the Companies’ and the Company Subsidiaries’ past employment practices. Commencing on the Closing Date and continuing through the date that is twelve
(12) months following the Closing Date, Purchaser shall provide or cause to be provided to each Business Employee, other than any such Business Employee covered by a collective bargaining agreement, levels of base pay and annual cash bonus
opportunities that are no less favorable than those provided to such Business Employee as of the Closing Date, and employee benefits that are substantially comparable in the aggregate to those provided to such Business Employee as of the Closing
Date (in all cases without regard to any equity-based incentive compensation, defined benefit pension plan, any retiree medical or other post-retirement welfare plan, or benefits under any frozen employee benefit plan; provided, that
notwithstanding the foregoing, Purchaser shall be required to take the value of such compensation and benefits into account as part of Purchaser’s obligation to provide employee benefits that are substantially comparable in the aggregate).

 (c) With respect to each of the Business Employees, Purchaser agrees to (i) assume and perform the obligations of El
Paso and its Affiliates under the severance plans set forth in Schedule 5.11(c) (the “Severance Plans”) from and after the Closing Date, in the same manner, and to the same extent that El Paso and its Affiliates would be
required to perform if the transactions contemplated by this Agreement had not taken place and (ii) if the Kinder Morgan Merger is consummated, treat the Closing as a “Change in Control” event for purposes of each of the Severance
Plans. Purchaser’s obligations under this Section 5.11(c) shall continue until at least the end of the Continuation Period (as 

  
 64 









 
defined in the Kinder Morgan Merger Agreement) or such longer period as may be required under any Severance Plan in effect as of the Execution Date; provided, that notwithstanding anything
to the contrary contained in this Section 5.11(c), Purchaser shall be solely responsible for any severance payments and benefits under the Severance Plans which may be payable to any Business Employees as a result of any termination of
employment deemed to have occurred under the Severance Plans on or following the Closing Date and Sellers shall be solely responsible for any severance payments or benefits under the Severance Plans which may be payable to any Business Employee as a
result of any termination of employment deemed to have occurred under the Severance Plans prior to the Closing Date (without any action of Purchaser). No later than five (5) days prior to the Closing Date, Sellers shall provide Purchaser with
the aggregate amount of all severance obligations under the Severance Plans in respect of Business Employees (assuming for such purpose that their termination of employment occurred on the day after the Closing Date). 

(d) Effective as of the Closing Date, all Business Employees shall cease to be active participants in all Seller Employee Plans (other
than Companies Employment Plans) and shall cease to accrue additional benefits under such plans for any periods after the Closing Date; provided that if the Closing Date occurs prior to the consummation of the Kinder Morgan Merger, the
Business Employees shall be deemed to have remained employed through the date of the consummation of the Kinder Morgan Merger for purposes of any rights such Business Employees may have to any accrued benefits and accelerated vesting under the
Seller Employee Plans as contemplated by the Kinder Morgan Merger Agreement. Effective as of the Closing Date, each of EP E&P Management, Brazil O&G and Egypt Production shall cease to be a participating employer in all Seller Employee
Plans, other than the Companies Employee Plans. 
 (e) As of the Closing Date, all Business Employees shall be eligible to
participate in and, if elected, shall commence participation in each of the employee benefit plans (within the meaning of Section 3(3) of ERISA), programs, policies, fringe benefits, or arrangements (whether written or unwritten) of Purchaser
or its Affiliates (collectively, “Purchaser Employee Plans”). Purchaser shall (i) to the extent within Purchaser’s control and ability under any Purchaser Employer Plan waive, or use commercially reasonable efforts to
cause any third-party insurance carriers to waive, all limitations as to pre-existing condition exclusions and waiting periods with respect to Business Employees and their spouses and dependents, if applicable, under any Purchaser Employee Plan
which is a welfare benefit plan and (ii) cause each Purchaser Employee Plan to provide, to the extent within Purchaser’s control and ability under any Purchaser Employee Plan, or use commercially reasonable efforts to cause any third-party
insurance carriers to provide, each Business Employee with credit for any co-payments and deductibles paid prior to the Closing Date in satisfying any deductible or out of pocket requirements under Purchaser Employee Plans for the plan year in which
the Closing Date occurs. 
 (f) Purchaser shall accept or cause to be accepted transfers from Sellers’ or any ERISA
Affiliate’s health care flexible spending account plan of each Business Employee’s account balance as of the Closing Date and credit such employee with such amounts under the applicable Purchaser Employee Plan. On and after the Closing
Date, Business Employees shall have no further claim for reimbursement under Sellers’ or any ERISA Affiliate’s health care flexible spending account and all claims must be submitted under the applicable Purchaser Employee Plan, including
expenses incurred prior to the Closing Date. 
 (g) Purchaser shall cause to be provided to each Business Employee credit for
prior service with any Seller or its Affiliates to the extent such service would be recognized if it had been performed as an employee of Purchaser or its Subsidiaries or Affiliates for all purposes (including vesting, eligibility, benefit accrual
and/or level of benefits) in all Purchaser Employee Plans (but not for benefit accruals under any defined benefit pension plan, any retiree medical or other post-retirement 

  
 65 









 
welfare plan, or benefits under any frozen employee benefit plan), including fringe benefit plans, vacation and sick leave policies, severance plans or policies, defined contribution pension
plans and matching contributions under defined contribution plans maintained or provided by Purchaser or its Subsidiaries or Affiliates in which such Business Employees are eligible to participate after the Closing Date; provided,
however, that, such service need not be recognized to the extent that such recognition would result in any duplication of benefits for the same period of service. 
 (h) During the calendar year in which the Closing occurs, Purchaser or its Affiliates shall maintain Sellers’ vacation policy with respect to each Business Employee and shall credit each such
individual with all earned but unused vacation as of the Closing Date with respect to any year prior to 2012, as determined under any and all of Sellers’ time off policies. Each Business Employee shall be entitled in 2012 to the greater of
(i) such Business Employee’s previously earned but unused vacation, determined as of the Closing Date under Sellers’ vacation policy or (ii) the number of vacation days with respect to calendar year 2012 to which such Business
Employee is entitled under Purchaser’s vacation policy, less any 2012 vacation days used by such Business Employee prior to the Closing Date. No Business Employee will be allowed to carry forward any unused vacation time beyond 2012 unless
allowed under Purchaser’s vacation policy. With respect to each year after 2012, Purchaser shall consider each Business Employee’s prior full-time service with Sellers in determining the amount of vacation the Business Employee will be
eligible for under Purchaser’s vacation policy. 
 (i) To the extent allowable by Law, Purchaser shall take any and all
necessary action to cause the trustee of a defined contribution plan of Purchaser or one of its Affiliates, if requested to do so by a Business Employee, to accept a “direct rollover” pursuant to Section 401(a)(31) of the Code of all
or a portion of such employee’s “eligible rollover distribution” (as defined in Section 402(c)(4) of the Code) from the El Paso Corporation Retirement Savings 401(k) Plan; provided, however, that Purchaser shall be
required to accept a rollover of a Business Employee’s plan loans only if such Business Employee rolls over one hundred percent (100%) of such Business Employee’s distribution from such plan. Except for plan loans, all “direct
rollovers” shall be made in cash and shall be subject to such administrative terms determined by Purchaser, including with respect to timing of any such “direct rollover.” 

(j) With respect to each Business Employee who is not actively at work and who is, as of the Closing Date, receiving any form of
pay/wage continuation (including short-term sickness, short-term disability, military leave or vacation pay) or unpaid leave (including Family and Medical Leave Act of 1993 leave or military leave), Sellers or the appropriate ERISA Affiliate shall
be responsible for any such payments due prior to the Closing Date and Purchaser shall be responsible for any payments due on or after the Closing Date. 
 (k) If a plant closing or a mass layoff occurs or is deemed to occur with respect to the Business Employees at any time on or after the Closing, Purchaser shall be solely responsible for providing all
notices required under the WARN Act and for taking all remedial measures, including the payment of all amounts, penalties, liabilities, costs and expenses if such notices are not provided. On the Closing Date, Sellers shall provide Purchaser with a
schedule of all Business Employees whose employment was terminated by Sellers in the ninety (90) day period prior to the Closing Date and their dates of termination. 
 (l) None of Purchaser, the Companies, the Company Subsidiaries or any of their respective Affiliates, shall assume or retain any Seller Employee Plans or any Liability whatsoever related to Seller
Employee Plans (other than the Companies Employee Plans and, as contemplated by Section 5.11(c), the Severance Plans), and Sellers shall retain sole responsibility for all Liabilities, claims, rights and payments under each Seller
Employee Plan (other than the Companies Employee Plans and, as contemplated by Section 5.11(c), the Severance Plans). 

  
 66 









 (m) Sellers shall provide, or cause to be provided, to Purchaser, on a timely basis, all
pertinent and requisite information reasonably requested by Purchaser to effect the transactions contemplated by this Section 5.11 and to facilitate the transition of the employment of Business Employees with Purchaser or its Affiliates.

 (n) Except as expressly provided in this Section 5.11, the Parties acknowledge and agree that no provision of
this Agreement shall be construed to: (i) create any right to any compensation or benefits whatsoever on the part of any Business Employee or other future, present or former employee of the Companies or the Company Subsidiaries, Purchaser or
its Affiliates; (ii) guarantee employment for any period of time or preclude the ability of Purchaser to terminate any employee, independent contractor or Business Employee for any reason at any time; (iii) require Purchaser to continue
any Purchaser Employee Plan, or other employee compensation or benefit plans or arrangements, or prevent the amendment, modification or termination thereof after the Closing Date or (iv) constitute an amendment to any Seller Employee Plan,
Purchaser Employee Plan, or other employee benefit or compensation plan or arrangements. 
 (o) Nothing in this
Section 5.11 or elsewhere in this Agreement shall be deemed to make any current or former employee, officer, director or independent contractor or any other individual associated therewith (including any beneficiary or dependent thereof)
a third-party beneficiary of this Agreement. 
 Section 5.12. Transition Committee and Transition Services
Agreement. Sellers and Purchaser agree to (i) as promptly as practicable after the date hereof, establish a transition committee to take certain actions, each as further set forth on Annex 2 and (ii) prior to Closing,
cooperate in good faith to design and implement a mutually agreeable transition plan with respect to the services listed on the schedules to the Transition Services Agreement. 
 Section 5.13. Replacement of Bonds, Letters of Credit and Guarantees; Insurance. 
 (a) The Parties understand that none of the bonds, letters of credit and guarantees, if any, posted by Sellers or any other Affiliate of the Companies (including the Companies and the Company Subsidiaries
to the extent Sellers or their Affiliates (except the Companies and the Company Subsidiaries) provide credit support for any such bonds, letters of credit or guarantees) with any Governmental Authority or third Person and relating to the E&P
Business are to be transferred to Purchaser. On or before the Closing, Purchaser shall use its commercially reasonable efforts to (i) obtain, or cause to be obtained in the name of Purchaser, replacements for the bonds, letters of credit and
guarantees identified in Schedule 5.13 (which, for the avoidance of doubt, shall contain letters of credit that are exclusive to the Companies or Company Subsidiaries only, and not letters of credit that are shared between or among the
Companies or Company Subsidiaries and El Paso or any subsidiary other than the Companies or Company Subsidiaries) and such other bonds, letters of credit and guarantees posted (or supported) by Sellers or such Affiliates that may arise between the
Execution Date and Closing in the ordinary course of business consistent with past practice that are disclosed in writing by Sellers to Purchaser at least five (5) Business Days prior to the Closing Date (collectively, the “Financial
Guaranties”) (which, for the avoidance of doubt, shall contain letters of credit that are exclusive to the Companies or Company Subsidiaries only, and not letters of credit that are shared between or among the Companies or Company
Subsidiaries and El Paso or any subsidiary other than the Companies or the Company Subsidiaries) and (ii) cause, effective as of the Closing, the cancellation or return to Sellers of the Financial Guaranties, and Sellers shall provide
reasonable cooperation to Purchaser in connection 

  
 67 









 
therewith. Purchaser may also provide evidence that such replacements are not necessary as a result of existing bonds, letters of credit or guarantees that Purchaser has previously posted as long
as such existing bonds, letters of credit or guarantees are adequate to secure the release of those posted (or supported) by Sellers. Schedule 5.13 identifies the bonds, letters of credit and guarantees posted (or supported) by Sellers or any
other Affiliate of the Companies (including the Companies and the Company Subsidiaries to the extent Sellers or their Affiliates (except the Companies and the Company Subsidiaries) provide credit support for any such bonds, letters of credit or
guarantees) with respect to the E&P Business as of the date noted on such Schedule, which Sellers may update through the Closing to include Financial Guaranties entered into after the date hereof in compliance with Sections 5.3 and
5.4. Notwithstanding anything to the contrary set forth herein, (i) neither the Company nor any Company Subsidiary shall be responsible for any collateral currently provided by Sellers under any shared insurance program and
(ii) with respect to letters of credit outstanding under any Third Party Loan facilities, Purchaser shall take such action to replace, cash collateralize or provide third Person backstops so as to enable a Debt Payoff Letter with respect the
applicable Third Party Loan to be received prior to Closing. 
 (b) If, as of the Closing, any one or more Financial Guaranties
has neither been released nor expired in accordance with its terms (the “Unreleased Financial Guaranties”), then Purchaser shall, at Closing, execute and deliver to Sellers for the benefit of Sellers and their Affiliates (to the
extent Sellers and such Affiliates are obligors under the Unreleased Financial Guaranties (the “Obligors”)) an indemnity agreement in form and substance reasonably acceptable to Sellers pursuant to which Purchaser, the Companies and
the Wholly-Owned Subsidiaries agree to indemnify the Obligors from and against all of their obligations arising under the Unreleased Financial Guaranties except to the extent such obligations are otherwise subject to Section 10.1(b). If
all Unreleased Financial Guaranties have not been so released or expired on or before one (1) year from the Closing Date, or should the indemnitor under any indemnity agreement delivered in connection with this Section 5.13(b) not
have and maintain a minimum investment grade rating on all of its outstanding senior unsecured long-term debt of at least BBB-, as determined by Standard & Poor’s Rating Agency Group, or Baa3, as determined by Moody’s Investors
Service, Inc., or, in each case, any nationally-recognized successor thereto (“Investment Grade”), Purchaser shall (i) cause an Affiliate of Purchaser or other third Person that, in each case, has, and for the previous five
(5) years has maintained, an Investment Grade senior unsecured long-term debt rating, to provide a guarantee in favor of Sellers that is in form and substance substantially similar to the indemnity agreement provided by Purchaser at Closing
pursuant to this Section 5.13 or (ii) provide, or cause to be provided, such other security for the obligations under the indemnity agreements that is in form, substance, and amount reasonably satisfactory to Sellers. No such
provision of an indemnity agreement shall relieve any Purchaser or any other Person providing an indemnity, guarantee, or other form of surety or security of its obligations thereunder. Purchaser agrees that Sellers will not have an adequate remedy
at Law if Purchaser violates (or threatens to violate) any of the terms of this Section 5.13. In such event, Sellers shall have the right, in addition to any other they may have, to obtain injunctive relief to restrain any breach or
threatened breach of the terms of this Section 5.13. 
 (c) Purchaser acknowledges and agrees that, effective upon
the Closing, all insurance coverage provided with respect to the Companies and the Company Subsidiaries pursuant to “claims made” or “claims first made” based policies maintained by Sellers (or any of their Affiliates, other than
any Company or Company Subsidiary) shall not be available to the Companies or the Company Subsidiaries under such policies but (subject to the terms of any relevant policy or arrangement) without prejudice to any claims or accrued claims which any
Company or Company Subsidiary may have at or prior to the Closing or based upon wrongful acts committed or alleged to be committed by any Company or Company Subsidiary prior to the Closing. Each Company and Company Subsidiary shall retain the
benefit of each “occurrence” based policy, which is underwritten and/or issued by any Person under which any Company or any Company Subsidiary is an insured, hereinafter referred to as “Occurrence Based Policies,” in
relation to events occurring prior to Closing in respect of claims for 

  
 68 









 
which it may have coverage thereunder, it being understood and agreed that such coverage shall be without prejudice to the rights of Sellers (provided, however that Sellers shall
not, and shall cause their Affiliates not to, terminate or amend or waive any of its rights under the Occurrence Based Policies), and other current or former Affiliates (other than the Companies and the Company Subsidiaries) to access and continue
to retain the benefit of such Occurrence Based Policies at and after the Closing as such policies were in effect on the date prior to the Closing Date. From and after the Effective Date, at the request of Purchaser, Sellers shall, and shall cause
the Companies and the Company Subsidiaries to, cooperate in the procurement of such named windstorm insurance coverage with respect to the Companies, the Company Subsidiaries and/or the E&P Business as may be requested by Purchaser; provided,
however that none of Sellers, the Companies or the Company Subsidiaries shall be required to make any payment of any premium for such named windstorm coverage prior to June 1, 2012. Promptly following any termination of this Agreement, if
at all, Purchaser shall reimburse Sellers for one hundred and fifty percent (150%) of any actual and reasonable out of pocket costs incurred by Sellers under the preceding sentence of this Section 5.13(c). 

(d) Purchaser acknowledges and agrees that, following the Closing, El Paso insurance coverage as set forth on Schedule 3.20 (less
and except any Company or Company Subsidiary policies in effect) (the “EPC Insurance Policies”) shall be terminated or modified to exclude coverage of all or any portion of the Companies or Company Subsidiaries by the Sellers, and,
as a result, Purchaser will need to, at or before Closing, obtain at its sole cost and expense replacement insurance, including insurance required by any third party to be maintained by any of the Companies or Company Subsidiaries. Purchaser further
acknowledges and agrees that Purchaser will need to provide to certain Governmental Authorities and third parties evidence of such replacement or substitute insurance coverage for the continued operations of the businesses of the Companies or
Company Subsidiaries following Closing. For avoidance of doubt, the Companies and Company Subsidiaries, as applicable, shall have the right to pursue claims or losses under such EPC Insurance Policies. 

Section 5.14. Surviving Agreements. At or prior to the Closing, the applicable Seller (or Affiliate of such Seller),
on the one hand, and the applicable Company (or applicable Company Subsidiary), on the other hand, shall terminate all Affiliate Transactions pursuant to termination agreements in form and substance reasonably acceptable to Purchaser, other than
those agreements (the “Surviving Agreements”) set forth in Schedule 5.14. 
 Section 5.15.
Preferential Purchase Rights; Consents. 
 (a) Promptly after the Execution Date, Sellers shall prepare and send
(i) notices to the holders of any consents that are set forth in Schedule 5.15 requesting consents to the transactions contemplated by this Agreement and (ii) notices to the holders of any applicable preferential rights to purchase,
rights of first negotiation or similar rights in compliance with the terms of such rights and requesting waivers of such rights. Prior to Closing, the Parties shall reasonably cooperate to cause such consents and waivers of preferential rights to
purchase or similar rights (or the exercise thereof) to be obtained and delivered prior to Closing; provided, however that Sellers and their Affiliates shall not be required to make payments or undertake obligations to or for the benefit of
the holders of such consent rights in order to obtain such consents and waivers. 
 (b) Should the holder of any preferential
purchase right set forth in Schedule 3.14 validly exercise the same (whether before or after Closing), then: 
 (i) the
Company or Wholly-Owned Subsidiary owning the applicable asset of the E&P Business shall transfer such asset to the holder of the preferential purchase right on the terms and provisions set out in the applicable preferential purchase right
provision; and 

  
 69 









 (ii) such Company or Wholly-Owned Subsidiary shall be entitled to the consideration paid by
such holder. 
 (c) Purchaser may, pursuant to a notice substantially in the form of a Title Defect Notice (a “Consent
Notice”), delivered on or before the Title Claim Date, allege that the consents identified thereon (that are not set forth on Schedule 5.15), if not obtained or waived, would impair (or cause a defect in) any Company’s or
Company Subsidiary’s title to any Company Mineral Interest, Company Well or Right of Way (each such consent, an “Alleged Required Consent”). With respect to any Alleged Required Consent, Sellers may, pursuant to written notice
to Purchaser on or before the date that is ten (10) Business Days after their receipt of a Consent Notice with respect thereto, agree or disagree that such Alleged Required Consent, if not obtained or waived, would so impair or cause a defect
in such title (provided that, if Sellers do not respond within such period, they shall be deemed to have disagreed that such Alleged Required Consent, if not obtained or waived, would so impair or cause a defect in such title). In the event
that any consent has not been raised by Purchaser pursuant to the foregoing provisions of this Section 5.15(c), this Section 5.15 (other than Section 5.15(h)) shall no longer apply thereto, and such consent shall
be solely and exclusively covered by Sections 5.15(h), 10.1(a)(iii) and 10.1(b)(iv). 
 (d) All disputes
as to whether an Alleged Required Consent would, if not obtained or waived, impair (or cause a defect in) any Company’s or Company Subsidiary’s title to any Company Mineral Interest, Company Well or Right of Way, or whether, and to what
extent, the rights of the holder of a Required Consent have been barred under applicable Law (each such dispute, a “Required Consent Dispute”), shall be determined by a Title Arbitrator pursuant to Section 1.5(i) of Annex
1. 
 (e) In the event any (i) consent set forth on Schedule 5.15, (ii) Alleged Required Consent that
Sellers and Purchaser have agreed in writing would, if not obtained or waived, impair (or cause a defect in) any Company’s or Company Subsidiary’s title to any Company Mineral Interest, Company Well or Right of Way or (iii) Alleged
Required Consent that a Title Arbitrator has finally determined, would, if not obtained or waived, impair (or cause a defect in) any Company’s or Company Subsidiary’s title to any Company Mineral Interest, Company Well or Right of Way
(each consent described in the foregoing clauses (i), (ii) and (ii), a “Required Consent”) is not obtained (in form and substance reasonably acceptable to Purchaser) on or before the end of the Consent Period and the rights of
the holder of such Required Consent are not otherwise barred pursuant to applicable Law, then Sellers shall pay to Purchasers promptly (but in any event within five (5) Business Days after the end of the Consent Period for the relevant Required
Consent) an amount equal to (x) in the case of a Company Mineral Interest or Company Well, the Allocated Value thereof (or portion thereof affected by the Required Consent), or (y) in the case of a Right of Way, the Damages actually
incurred or suffered by the Companies or Company Subsidiaries with respect to such Required Consent (such amount, the “Required Consent Adjustment Amount”). For the avoidance of doubt, neither the Title Threshold nor the Title
Deductible, nor either of the limitations set forth in Sections 10.1(d)(iv) and 10.4(c) shall apply to the determination of the Required Consent Adjustment Amount. As used herein, the term “Consent Period” means, with
respect to each Required Consent, the later of (x) the date that is nine (9) months after the Closing Date and (y) the date on which the Title Arbitrator finally resolves Required Consent Dispute (if any) with respect to such Required
Consent in accordance with the provisions of Section 1.5(i) of Annex 1; provided, however, that, if a lawsuit, arbitration or other proceeding is pending with respect to any Required Consent, the Consent Period with respect to
such Required Consent may, at Sellers’ option, be extended until the end of one (1) month after the final disposition of the same at Sellers’ sole cost, risk, and expense. 

(f) Except as set forth in Section 5.15(g), Section 10.1(a)(iii) and Section 10.1(b)(iv) shall be
the sole and exclusive remedy for all consent and alleged consent requirements covering (or created under) a Company Mineral Interest, Company Well or Right of Way that are not Required Consents. This Section 5.15 shall be the sole and
exclusive remedy of Purchaser with respect to Required Consents. 

  
 70 









 (g) Notwithstanding anything to the contrary herein, any consent right that provides it may
not be unreasonably withheld, shall not be subject to this Section 5.15, Section 10.1(a)(iii) or Section 10.1(b)(iv). 
 (h) Purchaser hereby covenants and agrees to bear fifty percent (50%) of each dollar of any Damages attributable to a claim for indemnity pursuant to Section 10.1(b)(iv), until the total
amount of such Damages (measured in the aggregate and not as to the fifty percent (50%) for which Purchaser is liable pursuant to this Section 5.15(h)) exceeds $15,000,000. 

Section 5.16. Transfer of Certain Assets Not Held by the Companies or Wholly-Owned Subsidiaries. At Closing, Sellers
or any of their Affiliates, as applicable, shall assign to Purchaser (or its designee) certain personal property set forth in Schedule 5.16 (as may be modified by the agreement of the Parties to reflect any matters that the Parties agree to
between the Execution Date and Closing) pursuant to an assignment substantially in the form set forth on Exhibit E (the “Personal Property Assignment”). EXCEPT AS OTHERWISE PROVIDED IN THE PERSONAL PROPERTY ASSIGNMENT, THE
ASSIGNMENT OF SUCH PERSONAL PROPERTY SHALL BE “AS IS, WHERE IS” WITH ALL FAULTS, AND ALL REPRESENTATIONS AND WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF CONDITION, QUALITY, SUITABILITY, DESIGN, MARKETABILITY, INFRINGEMENT,
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR CONFORMITY TO MODELS OR SAMPLES OF MATERIALS ARE HEREBY DISCLAIMED. 

Section 5.17. Directors’ and Officers’ Indemnification. 

(a) After Closing, the Organizational Documents of the Companies and the Wholly-Owned Subsidiaries shall contain provisions no less
favorable with respect to indemnification than are set forth in their respective Organizational Documents immediately prior to Closing and set forth in any indemnification agreement currently in effect between any Seller, Company or Wholly-Owned
Subsidiary and any current or former officer or director of any Company or Wholly-Owned Subsidiary or any current or former Business Employee, which provisions shall not be amended, repealed or otherwise modified for a period of six (6) years
from the Closing Date in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Closing Date, were directors, officers, fiduciaries or agents of any Company or Wholly-Owned Subsidiary or Business
Employees; provided, that, in the event that any claim for indemnification is asserted or made within such six (6) year period, all rights to indemnification in respect of such claim shall continue until the final disposition of such
claim. 
 (b) This Section 5.17 is intended to be for the benefit of, and shall be enforceable by, present or
former directors and officers of each Company and Wholly-Owned Subsidiary, their respective heirs and personal representatives and shall be binding on Purchaser and its successors and assigns. In the event that Purchaser or any of its successors or
assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets
to any Person (including by dissolution), then, and in each such case, Purchaser shall cause proper provision to be made so that the successors and assigns of Purchaser assume and honor the obligations set forth in this Section 5.17. The
agreements and covenants contained herein shall not be deemed to be exclusive of any other rights to which any such present or former director or officer is entitled, whether pursuant to Law, Contract or otherwise. Nothing in this Agreement is
intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been 

  
 71 









 
in existence with respect to any Company or Wholly-Owned Subsidiary or their respective officers and directors and Business Employees, it being understood and agreed that the indemnification
provided for in this Section 5.17 is not prior to or in substitution for any such claims under any such policies. 

Section 5.18. Title Matters. The Parties shall comply in all respects with the provisions of Annex 1 and hereby
agree that the rights and remedies of Purchaser set forth in Annex 1 represent Purchaser’s sole and exclusive rights and remedies with respect to any defect in title with respect to the Company Properties. 

Section 5.19. Financing. 
 (a) Purchaser shall use reasonable best efforts (taking into account the expected timing of the Marketing Period) to take all actions and to do or cause to be done all things necessary, proper or
advisable to obtain the proceeds of the Financing on the terms and conditions described in the Financing Letters (provided, that Purchaser may (i) amend the Debt Commitment Letter to add lenders, lead arrangers, bookrunners, syndication
agents or similar entities who had not executed the Debt Commitment Letter as of the date of this Agreement so long as such Persons are reasonably acceptable to Sellers or (ii) otherwise replace or amend the Debt Commitment Letter so long as
such action would not reasonably be expected to delay or prevent the Closing and the terms are not materially less beneficial to Purchaser, with respect to conditionality, than those in the Debt Commitment Letter as in effect on the date of this
Agreement). Purchaser shall not permit any amendment or modification to be made to, or any waiver of any provision under, the Financing Letters without the prior written consent of Sellers if such amendment, supplement, modification or waiver:

 (i) with respect to the Financing Letters, reduces the aggregate amount of the Financing (including by increasing the amount
of fees to be paid or original issue discount as compared to such fees and original issue discount contemplated by the Debt Commitment Letter and related fee letters in effect on the date hereof unless the Debt Financing or the Equity Financing is
increased by such amount); 
 (ii) (A) imposes new or additional conditions or (B) otherwise adversely expands, amends or
modifies any of the conditions precedent to the Financing, or otherwise expands, amends or modifies any other provision of the Financing Letters, in the case of clause (B), in a manner that would reasonably be expected to prevent or materially delay
the ability of Purchaser to consummate the Closing on the Closing Date; or 
 (iii) would otherwise materially adversely impact
the ability of Purchaser to enforce its rights against other parties to the Financing Letters or otherwise to timely consummate the transactions contemplated by this Agreement. 

Purchaser shall promptly deliver to Sellers copies of any such amendment, modification, waiver or replacement. For purposes of this
Agreement, references to “Financing” or “Debt Financing,” as applicable, shall include the financing contemplated by the Financing Letters as permitted to be amended, modified or replaced by this Section 5.19(a) or
5.19(c) and references to “Debt Commitment Letter” shall include such documents as permitted to be amended, modified or replaced by this Section 5.19(a) or 5.19(c). 

(b) Purchaser shall use reasonable best efforts to: 
 (i) maintain in effect the Financing Letters; 

  
 72 









 (ii) negotiate and enter into definitive agreements (which with respect to the bridge
facility documentation shall not be required until reasonably necessary in connection with the funding of the Financing), and provide Sellers with copies of all substantially final drafts of documents with respect to the Debt Financing on the terms
and conditions contained in the Debt Commitment Letter (including the “flex” provisions contained in any related fee letter) or on other terms in the aggregate materially no less favorable to Purchaser, as to conditionality, than the terms
and conditions in the Debt Commitment Letter; provided, that in no event shall any such definitive agreement contain terms (other than those included in the Debt Commitment Letter) that would reasonably be expected to prevent or materially
delay the Closing; 
 (iii) satisfy (or, if deemed advisable by Purchaser, seek the waiver of) on a timely basis all conditions
applicable to Purchaser that are within its control as set forth in the Financing Letters and to comply with all of its material obligations pursuant to the Debt Commitment Letter; 

(iv) upon satisfaction of such conditions, cause the funding of the Debt Financing at or prior to Closing (together with other sources
of funds, including the Equity Financing, with respect to amounts required to pay the Required Amounts); 
 (v) enforce all of
its rights under the Debt Commitment Letter (including, for the avoidance of doubt, by instituting litigation in respect thereof); provided that all of the conditions to Purchaser’s obligations under Section 6.2 (except those
to be satisfied at the Closing) have been satisfied or waived; and 
 (vi) give Sellers prompt notice of any material breach by
any party to the Debt Commitment Letters of which Purchaser has become aware or any termination of any of the Commitment Letters. Purchaser shall keep the Company apprised of material developments relating to the Financing and shall give the Company
prompt notice of any material adverse change with respect to such Financing. Without limiting the foregoing, Purchaser agrees to notify Sellers promptly if at any time any financing source that is a party to the Debt Commitment Letter notifies
Purchaser that such source no longer intends to provide financing on the terms set forth therein. 
 Notwithstanding anything to
the contrary in this Agreement, nothing contained in this Section 5.19(b) shall require, and in no event shall the reasonable best efforts of Purchaser be deemed or construed to require, Purchaser or any Affiliate thereof to
(i) seek the Equity Financing from any source other than those counterparty to, or in any amount in excess of that contemplated by, the Equity Funding Letter or (ii) pay any material fees in excess of those contemplated by the Financing
Letters (including pursuant to the “flex” provisions contained in any fee letter relating to the Debt Financing). 

(c) If any portion of the Debt Financing becomes unavailable on the terms and conditions contemplated in the Debt Commitment Letter or
the Debt Commitment Letter is terminated or modified in a manner materially adverse to Purchaser for any reason, Purchaser shall promptly notify Sellers in writing and shall use its reasonable best efforts to arrange to obtain alternative financing
from alternative sources for such portion as promptly as practicable following such event on terms no less favorable to Purchaser in any material respect as those contained in the Debt Commitment Letter and in an amount sufficient, together with the
Equity Financing and cash on hand of the Companies, if any, to fund the Required Amount (the “Alternate Financing”) and, if obtained, will provide Sellers with a copy of, a new financing commitment that provides for at least the
same amount of financing as provided under the Debt Commitment Letter originally issued, to the extent needed to fund the Required Amount, and on terms and conditions (including all terms, termination rights, flex provisions and funding conditions)
no less favorable in any material respect to Purchaser than those included in the Debt Commitment Letter (an “Alternate Debt Commitment Letter”). Purchaser shall use 

  
 73 









 
its reasonable best efforts (taking into account the expected timing of the Marketing Period) to take, or cause to be taken, all actions and things necessary, proper or advisable to arrange
promptly and consummate the Alternate Financing on the terms and conditions described in any Alternate Debt Commitment Letter, including by complying with its obligations under clause (b) above as though the references therein to Debt
Commitment Letter and Debt Financing were instead references to the Alternate Financing and the Alternate Debt Commitment Letter. 
 Notwithstanding anything to the contrary in this Agreement, Purchaser may enter discussions regarding, and may enter into arrangements and agreements relating to the Financing to add other equity
providers, so long as in respect of any such arrangements and agreements, the following conditions are met: (i) the aggregate amount of the Equity Financing is not reduced; (ii) the arrangements and agreements, in the aggregate, would not
be reasonably likely to delay or prevent the Closing and (iii) the arrangements and agreements would not diminish or release the pre-closing obligations of the parties to the Equity Funding Letter, adversely affect the rights of Purchaser to
enforce its rights against the other parties to the Equity Funding Letter, or otherwise constitute a waiver or reduction of Purchaser’s rights under the Equity Funding Letter. 

For the avoidance of doubt, in the event that (i) all or any portion of the Debt Financing contemplated to be raised in lieu of the
bridge financing contemplated under the Debt Commitment Letter has not been consummated and (ii) the conditions set forth in Article 6 have been satisfied or waived (and which are, to the extent not satisfied or waived, at the time of
the termination of this Agreement, capable of being satisfied if the Closing were to occur at such time) and (iii) all of the conditions set forth in the Debt Commitment Letters have been satisfied or waived (other than those conditions which
by their nature are to be satisfied at Closing, but subject to the satisfaction of those conditions), Purchaser shall use reasonable best efforts to cause the proceeds of the bridge facility contemplated by the Debt Commitment Letters to be used to
cause the Closing to occur in accordance with the terms and conditions hereunder. 
 (d) Prior to the Closing Date or as
expressly provided for in subclause (vi) below, Sellers shall use their respective reasonable best efforts to provide, and shall cause each Company and each Company Subsidiary to use reasonable best efforts to provide, and shall use reasonable
best efforts to cause its respective directors, officers, employees, consultants, agents, financial advisors, attorneys, accountants or other representatives (collectively, “Representatives”) to use reasonable best efforts to
provide, to Purchaser such cooperation as may be reasonably requested by Purchaser; provided, that such requested cooperation does not materially and adversely interfere with the E&P Business. Such cooperation shall include: 

(i) as promptly as reasonably practical, (x) furnishing Purchaser and Purchaser’s financing sources and their respective
Representatives with the Required Information; provided that Sellers shall provide to Purchaser, or shall cause to be provided to Purchaser, the audited consolidated balance sheets and related statements of income, stockholders’ equity
and cash flows of the Companies and Company Subsidiaries for 2011 no later than March 15, 2012 and (y) inform Purchaser if the Companies or the Company Subsidiaries shall have knowledge of any facts that would likely require the
restatement of such financial statements for such financial statements to comply with the Accounting Principles; 
 (ii)

engineering firms reasonably acceptable to Purchaser and the debt financing sources in respect of any such reports prepared as of December 31 of each year and six (6) months thereafter, and including consents from such independent
petroleum engineering firms to inclusion of such reports in any offering documents, private placement memoranda, bank information memoranda, prospectuses and similar documents in connection with the Financing; 

(v) (A) using reasonable best efforts to obtain and provide customary (x) reserve engineers’ “comfort” for Rule 144A

(y) accountants’ comfort letters, and (B) using commercially reasonable efforts to obtain and provide appraisals, and surveys, and using reasonable best efforts to permit and/or facilitate environmental and other inspections
(including providing reasonable access to Purchaser and its Representative to all properties of proved oil and gas reserves included in the Reserve Reports and other owned or leased real property for such purposes), title information, and other
documentation and items relating to the Debt Financing, as contemplated by the Debt Commitment Letter or reasonably requested by Purchaser and, if requested by Purchaser, to cooperate with and assist Purchaser in obtaining such documentation and
items, with the understanding that depending on the specific properties represented and the timing of the Closing Date, additional technical work may be required before post-dated “comfort” can be provided; 

(vi) both before the Closing and, to the extent reasonably necessary to allow Purchaser or any of its Affiliates to consummate a
securities offering or comply with SEC requirements, after the Closing, providing appropriate representations in connection with the preparation of financial statements and other financial data of each Company and each Company Subsidiary and
requesting accountants’ consents in connection with the use of each Company’s and each Company Subsidiary’s financial statements in offering documents, prospectuses, Current Reports on Form 8-K and other documents to be filed with the
SEC; 
 (vii) using reasonable best efforts to assist Purchaser in connection with the preparation of pro forma financial

provided Sellers or the Companies with information relating to the proposed debt and equity capitalization that is required for such pro forma financial information in financial reports; 

(viii) using reasonable best efforts to (x) provide monthly financial statements (excluding footnotes) within fifteen
(15) Business Days of the end of each month prior to the Closing Date and (y) providing quarterly financial statements within forty-five (45) days of the end of each fiscal quarter prior to the Closing Date;

 (e) Sellers shall, and shall cause the Companies to, use reasonable best
efforts to periodically update any Required Information provided to Purchaser as may be necessary so that such Required Information is (i) Compliant, (ii) meets the applicable requirements set forth in the definition of “Required
Information” and (iii) would not, after giving effect to such update(s), result in the Marketing Period to cease to be deemed to have commenced. For the avoidance of doubt, Purchaser may, to most effectively access the financing markets,

Purchaser reasonably requests Sellers to file a Current Report on Form 8-K pursuant to the Exchange Act that contains material non-public information with respect to each Company and each Company Subsidiary, which Purchaser reasonably determines (in
consultation with Sellers) to include in a customary offering memorandum for the Debt Financing, then, upon Sellers’ review of and reasonable satisfaction with such filing, Sellers shall file such Current Report on Form 8-K.

the extent any of the foregoing arises from the bad faith, gross negligence or willful misconduct of, or material breach of this Agreement by, any of the Companies, any of the Company Subsidiaries or any of their respective Affiliates and
Representatives. 
 Section 5.20. Confidentiality. After the Closing, each Seller shall hold and shall cause
each of its Affiliates to hold, and each Seller shall use its reasonable best efforts to cause its and its Affiliates’ respective Representatives to hold, in confidence, unless compelled to disclose by judicial or administrative process, Order

respective directors, officers, employees, Affiliates or equity holders, in each case arising out of, resulting from or relating to actions, omissions, facts or circumstances occurring, arising or existing at or prior to the Closing, in each case,
other than with respect to claims under this Agreement or any Surviving Agreement and (ii) Purchaser shall cause each Company, each of its subsidiaries, on its own behalf and on behalf of its Affiliates or their respective heirs, estate,

respective directors, officers, employees, Affiliates or equity holders in such Seller’s capacity as an equity 

  
 77 









 
holder, member, manager or similar capacity of any Company, in each case arising out of, resulting from or relating to actions, commissions, facts or circumstances occurring, arising or existing
at or prior to the Closing, in each case, other than with respect to claims under this Agreement or any Surviving Agreement. 

Section 5.22. Seismic Transfer. Until a date that is one hundred eighty (180) days after the Closing, Sellers and
Purchaser shall use commercially reasonable efforts to obtain replacement licenses in the name of Purchaser (or its designee), or approval for transfer of the existing licenses, for seismic data relating solely to the Company Properties which
Sellers, the Companies, or the Company Subsidiaries hold under license and the transfer of which is prohibited or subjected to payment of a fee or other consideration in connection with the transactions contemplated by this Agreement. All costs of
such replacement licenses or license transfers shall be borne by Purchaser. Purchaser and Sellers shall reasonably cooperate with each other in this effort; provided, however, that Sellers (and, until the Closing, Companies and Company

to a Pre-Effective Time Period (“Pre-Effective Time Non-Income Taxes,” and together with Pre-Closing Income Taxes, “Sellers Indemnified Taxes”); (iii) any Taxes of a Person other than a Company or Company
Subsidiary for which any Company or Company Subsidiary is liable by virtue of any affiliation, merger or other event occurring prior to the Closing (including pursuant to Treasury Regulations Sections 1.1502-6 or 1.1502-78 (or any similar provision
of state, local or non-U.S. law)); (iv) any breach of a Seller Fundamental Tax Representation or Seller Fundamental Tax Covenant (provided, that (A) for purposes of this Section 8.1(a)(iv) only, any breach of any such
Seller Fundamental Tax Representation or Seller Fundamental Tax Covenant shall be determined without reference to any materiality qualifier with respect thereto , and (B) to the extent that a breach of any covenant or agreement set forth in
Section 5.4(m) gives rise to a Post-Effective Time Period Non-Income Tax, the Tax Loss relating to such Post-Effective Time Period Non-Income Tax shall be reduced by the amount that such Post-Effective Time Period Non-Income Tax would
have been had no such breach occurred); (v) the restructuring steps described in Section 8.10(a) or the actions of Sellers or their Affiliates pursuant to Section 5.7; and (vi) any withholding Taxes relating to the
sale of the Brazilian Shares hereunder. Notwithstanding the preceding sentence, Sellers shall have no obligation to indemnify the Tax Indemnified Purchaser Parties from and against, and Purchaser hereby waives any claims against, and releases,
Sellers from any Tax Losses relating to, or suffered or incurred by, any EgyptCo. Subject to Section 8.1(d), Section 8.8 and Section 10.4(d), Sellers shall pay the Tax Indemnified Purchaser Parties with respect to
a Tax Loss under this Section 8.1(a) promptly in cleared funds no later than the later of (i) two (2) Business Days before the date on which the relevant Taxes (if applicable) are required to be paid and (ii) five
(5) Business Days after Sellers’ receipt of notice and supporting work papers (or other appropriate documentation) from Purchaser of Sellers’ liability therefor. 

(b) Tax Indemnification by Purchaser. Subject to Section 8.8, from and after Closing, Purchaser shall be liable for,
and shall indemnify and hold harmless each Seller and its Affiliates (other than the Companies and Company Subsidiaries) (each, a “Tax Indemnified Seller Party”) from and against all Tax Losses incurred by a Tax Indemnified Seller
Party arising out of (i) any Income 

  
 82 









 
Taxes imposed on, relating to, or incurred by a Company or Company Subsidiary and attributable to any Post-Closing Period and any Non-Income Taxes imposed on, relating to, or incurred by a
Company or Company Subsidiary and attributable to any Post-Effective Time Period (in each case, other than any such Taxes (A) for which such Company or Company Subsidiary is liable by virtue of any affiliation, merger or other event occurring
prior to the Closing (including pursuant to Treasury Regulations Sections 1.1502-6 or 1.1502-78 (or any similar provision of state, local or non-U.S. law)), (B) that result from a breach of a Seller Fundamental Tax Representation or a Seller
Fundamental Tax Covenant (provided, that for purposes of this Section 8.1(b)(i)(B) only, any breach of any such Seller Fundamental Tax Representation or Seller Fundamental Tax Covenant shall be determined without reference to any
materiality qualifier with respect thereto), (C) that result from the restructuring steps described in Section 8.10(a) or (D) that are withholding Taxes relating to the sale of the Brazilian Shares hereunder))
(“Purchaser Indemnified Taxes”) and (ii) any Transfer Taxes required to be borne by Purchaser pursuant to Section 11.3. Subject to Section 8.8, Purchaser shall pay Sellers or their Affiliates with
respect to a Tax Loss under this Section 8.1(b) promptly in cleared funds no later than the later of (i) two (2) Business Days before the date on which the relevant Taxes (if applicable) are required to be paid and
(ii) five (5) Business Days after Purchaser’s receipt of notice and supporting work papers (or other appropriate documentation) from Sellers of Purchaser’s liability therefor. 

(c) Straddle Period Taxes. Whenever it is necessary for purposes of this Agreement to determine the portion of any Taxes of or
with respect to any Company or Company Subsidiary for a Straddle Income Period which is allocable to the Pre-Closing Period or the Post- Closing Period or for a Straddle Non-Income Period which is allocable to the Pre-Effective Time Period or the
Post-Effective Time Period, as the case may be, the determination shall be made as if each of the Companies and the Company Subsidiaries was not a member of its respective Seller’s consolidated, affiliated, combined or unitary group for Tax
purposes. Any Income Taxes attributable to a Straddle Income Period will be allocated between the Pre-Closing Period and the Post-Closing Period based on an interim closing of the books (such Taxes allocable to the Pre-Closing Period being
determined as if such taxable period ended as of the Closing Date). Any Non-Income Taxes attributable to a Straddle Non-Income Period will be allocated between the Pre-Effective Time Period and the Post-Effective Time Period based upon the number of
days in the applicable period falling on or before, or after, December 31, 2011. To the extent necessary, a Seller shall estimate Taxes based on Seller’s liability for Taxes with respect to the same or similar Tax item in the immediately
preceding year. Notwithstanding anything to the contrary herein, (i) any franchise Tax paid or payable with respect to each Company or Company Subsidiary shall be allocated to the taxable period during which the income, operations, assets or
capital comprising the base of such Tax is measured, regardless of whether the right to do business for another taxable period is obtained by the payment of such franchise Tax, (ii) any ad valorem or property Taxes paid or payable with respect
to the assets of the E&P Business shall be allocated to the taxable period applicable to the ownership of the assets of the E&P Business regardless of when such Taxes are assessed and (iii) any severance, production and similar Taxes
based upon or measured by the quantity of or the value of the production of Hydrocarbons shall be apportioned between Sellers and Purchaser based on the number of units or value of production actually produced and subject to Tax, as applicable, on
or before, and after, December 31, 2011 and any such Taxes shall be deemed attributable to the period during which the relevant production occurred. 
 (d) Survival of Tax Indemnification. The right to assert an indemnification claim pursuant to this Section 8.1 shall survive Closing and remain in full force and effect until the date
which is sixty (60) days after the date upon which liability to which any such claim may relate is barred by all applicable statutes of limitations (including all periods of extension, whether automatic or permissive). 

  
 83 









 Section 8.2. Preparation and Filing of Company or Company Subsidiary Tax
Returns. 
 (a) Subject to Section 8.2(b), with respect to each Tax return, declaration, report, claim for
refund or information return or statement relating to Taxes, including any schedule or attachment thereto, and including any amendment thereof (a “Tax Return”) that is required to be filed for, by or with respect to a Company or
Company Subsidiary after the Closing Date, Purchaser shall cause such Tax Return to be prepared and, subject to Sellers’ obligations under Section 8.1, shall cause each Company to file timely such Tax Return with the appropriate
Governmental Authority and pay timely the amount of Taxes shown to be due on such Tax Return. Subject to Section 8.8, Sellers shall pay Purchaser or its designee in cleared funds an amount equal to all Sellers Indemnified Taxes due in
respect of such Tax Returns no later than the later of (i) three (3) Business Days prior to the due date (including extensions) for such Tax Returns and (ii) five (5) Business Days after Sellers’ receipt of notice and
supporting work papers (or other appropriate documentation) from Purchaser of Sellers’ liability therefor). 
 (b) With
respect to each Tax Return relating to Income Taxes that is required to be filed after the Closing Date for, by or with respect to any consolidated, combined or unitary group of which a Company or Company Subsidiary is a member (but the parent
thereof is not a Company or Company Subsidiary), Sellers shall cause such Tax Return to be prepared and shall cause such Tax Return to be timely filed with the appropriate Governmental Authority and pay timely the amount of Taxes shown to be due on
such Tax Return. 
 (c) Any Tax Return to be prepared pursuant to Section 8.2(a) in respect of a Pre-Effective Time
Period (or, in the case of a Tax Return relating to Income Taxes, in respect of a Pre-Closing Period) and any Tax Return to be prepared pursuant to Section 8.2(b) shall, in each case, shall be prepared in a manner consistent with
practices, elections, and methods of accounting followed in prior years with respect to similar Tax Returns for the applicable entity, except for changes required by applicable Law, subject to the return preparer’s ethical and legal obligations
under applicable Laws. 
 (d) With respect to Tax Returns of a Company or Company Subsidiary for a Pre-Effective Time Period or
Pre-Closing Period to be filed after the Closing Date, if Sellers may be liable for any portion of the Tax payable in connection with such Tax Return, Purchaser shall prepare and deliver to Sellers a copy of such return and any schedules, work
papers and other documentation then available that are relevant to the preparation of the portion of such return for which Sellers are or may be liable under this Agreement not later than forty-five (45) days before the date on which the Tax
Return is due to be filed (taking into account any valid extensions) (the “Due Date”) (or, in the case of ad valorem property Taxes, within thirty (30) days of receipt of the bill for such ad valorem property Taxes from the
applicable Governmental Authority) or, in the case of any such Tax Returns due within sixty (60) days after the Closing Date, as soon as reasonably practicable. Purchaser shall not file such return or cause such return to be filed until the
earlier of either the receipt of written notice from Sellers indicating Sellers’ consent thereto, or the Due Date. If Sellers dispute any item on such Tax Return, they shall notify Purchaser of such disputed item (or items) and the basis for
their objection. The Parties shall act in good faith to resolve any such dispute prior to the date on which such Tax Return is required to be filed. If the Parties cannot resolve any disputed item, the item in question shall be resolved by an
independent accounting firm mutually acceptable to Sellers and Purchaser. The fees and expenses of such accounting firm shall be borne equally by Sellers and Purchaser. 
 (e) Notwithstanding any other provision of this Agreement to the contrary, Purchaser and its Affiliates shall be entitled to prepare and file all Tax Returns, and to conduct all Tax audits, adjustments,
claims, examinations, assessments or other proceedings, with respect to their operations, assets, and activities for any Tax period beginning after the Closing Date or with respect to 

  
 84 









 
any consolidated, combined or unitary group of which Purchaser or any of its Affiliates is a member in such manner as Purchaser may determine in Purchaser’s sole discretion; provided,
however, that this Section 8.2 shall not limit Purchaser’s liability under this Agreement for breaches of covenants or agreements contained in Sections 2.2(b), 8.7 or 10.1(h). 

Section 8.3. Tax Sharing Agreement. Effective as of December 31, 2011 (in respect of Non-Income Taxes) and the
Closing Date (in respect of Income Taxes), any tax indemnity, sharing, allocation or similar agreement or arrangement (a “Tax Sharing Agreement”) that may be in effect between or among a Company or Company Subsidiary, on the one
hand, and its Seller or any of its Affiliates (other than the Companies and the Company Subsidiaries), on the other hand, shall be extinguished in full as the Tax Sharing Agreement relates to such Company or Company Subsidiary, and any liabilities
or rights existing under any such agreement or arrangement by or with respect to a Company or Company Subsidiary shall cease to exist and shall no longer be enforceable as to all past, present and future taxable periods. 

Section 8.4. Access to Information. 
 (a) From and after Closing, each Seller shall grant to Purchaser (or its designees) reasonable access at all reasonable times to the information, books and records relating to a Company or Wholly-Owned
Subsidiary within the possession of such Seller (including work papers and correspondence with taxing authorities), and shall afford Purchaser (or its designees) the right (at Purchaser’s expense) to take extracts therefrom and to make copies
thereof, to the extent reasonably necessary to permit Purchaser (or its designees) to prepare Tax Returns, to conduct negotiations with Tax authorities, and to implement the provisions of, or to investigate or defend any claims between the Parties
arising under, this Agreement. 
 (b) From and after Closing, Purchaser shall grant to Sellers (or Sellers’ designees)
reasonable access at all reasonable times to the information, books and records relating to the Companies or Wholly-Owned Subsidiaries within the possession of Purchaser, the Companies or Wholly-Owned Subsidiaries (including work papers and
correspondence with taxing authorities, but excluding work product of and attorney-client communications with any of Purchaser’s legal counsel and personnel files), and shall afford Sellers (or Sellers’ designees) the right (at
Sellers’ expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit Sellers (or Sellers’ designees) to prepare Tax Returns, to conduct negotiations with, or contest deficiencies asserted
by, Tax authorities, and to implement the provisions of, or to investigate or defend any claims between the Parties arising under, this Agreement. 
 (c) Each of the Parties hereto will preserve and retain all schedules, work papers and other documents within the Party’s possession relating to any Tax Returns of or with respect to Taxes of the
Companies or Wholly-Owned Subsidiaries or to any claims, audits or other proceedings affecting the Companies or Wholly-Owned Subsidiaries until the expiration of the statute of limitations (including extensions) applicable to the taxable period to
which such documents relate or until the final determination of any controversy with respect to such taxable period, and until the final determination of any payments that may be required with respect to such taxable period under this Agreement.

 (d) At either Purchaser’s or Sellers’ request, the other Party shall provide reasonable access to Purchaser’s
or Sellers’, as the case may be, and their respective Affiliates’ (including the Companies’ and Wholly-Owned Subsidiaries’) personnel who have knowledge of the information described in this Section 8.4. In addition,
at Sellers’ request, Purchaser shall provide to Sellers in a timely manner such information and assistance as Purchaser may reasonably request (including pro forma Tax Returns and supporting information and documentation related thereto) so as
to permit Sellers to accurately prepare and timely file any Tax Returns of Sellers or their Affiliates that include tax attributes of any Company or Company Subsidiary. 

  
 85 









 (e) In the case of any Tax Return to be prepared pursuant to the provisions of this
Article 8, if the Party that is not preparing the Tax Return (or any of its Affiliates) is required to pay any Taxes shown on the Tax Return, then the Party preparing the Tax Return shall provide the Party not preparing the Tax Return with
appropriate documentation and computations reasonably requested by such latter Party supporting the determinations made by the Party preparing the Tax Return as to the amount of Tax so due by the Party not preparing the Tax Return (or any of its
Affiliates). 
 (f) Any information obtained under this Section 8.4 or Section 8.9 shall be kept
confidential, except as may be otherwise necessary in connection with the filing of Tax Returns or in the conduct of a Tax Audit or other Tax proceeding. 
 Section 8.5. Contest Provisions. 
 (a) From and after Closing,
each of Purchaser, on the one hand, and Sellers, on the other hand (the “Tax Indemnified Person”), shall notify the chief tax officer (or other appropriate person) of New EPE or Purchaser, as the case may be, in writing within
fifteen (15) days of receipt by the Tax Indemnified Person of written notice of any pending or threatened audits, adjustments, claims, examinations, assessments or other proceedings with respect to a Company or Wholly-Owned Subsidiary (a
“Tax Audit”) which are likely to affect the liability for Taxes of such other Party. If the Tax Indemnified Person fails to give such timely notice to the other Party, it shall not be entitled to indemnification for any Taxes
arising in connection with such Tax Audit to the extent such failure to give notice actually and materially adversely affects the other Party. 
 (b) If such Tax Audit relates solely to Taxes for which Purchaser is indemnified under Section 8.1(a), Sellers shall, at their expense, conduct and control the defense and settlement of such
Tax Audit, but Purchaser shall have the right to participate in such Tax Audit at its own expense, and Sellers shall not be able to settle, compromise and/or concede any portion of such Tax Audit that is reasonably likely to affect the Tax liability
of Purchaser, a Company or a Company Subsidiary for any post-Closing Period without the consent of Purchaser, which consent shall not be unreasonably withheld, delayed or conditioned; provided, that if Sellers fail to assume control of the
conduct of any such Tax Audit within a reasonable period following the receipt by Sellers of notice of such Tax Audit, Purchaser shall have the right to assume control of such Tax Audit and shall be able to settle, compromise and/or concede such Tax
Audit in its sole discretion. If such Tax Audit relates to Taxes for which Purchaser is indemnified under Section 8.1(a) and Taxes for which Purchaser is not indemnified under Section 8.1(a), Purchaser shall control the
conduct of such Tax Audit, but Sellers shall have the right to participate in such Tax Audit at their own expense, and Purchaser shall not settle, compromise and/or concede such Tax Audit without the consent of Sellers, which consent shall not be
unreasonably withheld, delayed or conditioned. If such Tax Audit relates solely to Taxes for which Purchaser is not indemnified under Section 8.1(a), Purchaser shall conduct and control the defense and settlement of such Tax Audit.

 Section 8.6. Post-Closing Actions Which Affect Sellers’ Tax Liability. Except to the extent required
by applicable Laws, neither Purchaser, on the one hand, nor Sellers, on the other hand, shall and they shall not permit their respective Affiliates, including the Companies and the Company Subsidiaries, to amend any Tax Return of the Companies or
the Company Subsidiaries with respect to a Pre-Effective Time Period without the prior written consent of the other (such consent not to be unreasonably withheld, delayed or conditioned) if such amended Tax Return would materially increase the
amount of Taxes for which the other Party is responsible. 

  
 86 









 Section 8.7. Refunds. Purchaser agrees to pay to Sellers any refund
received together with any interest thereon from a Governmental Authority after the Closing by Purchaser or its Affiliates, including the Companies and the Company Subsidiaries in respect of any Non-Income Taxes of any Company or Company Subsidiary
for a Pre-Effective Time Period and any Income Taxes of any Company or Company Subsidiary for a Pre-Closing Period (in both cases, other than any refund resulting from the carryback of a net operating loss or other Tax attribute from a period
beginning after the Closing Date to a period ending on or prior to the Closing Date, which refund shall be for the account of Purchaser) to the extent not taken into account in determining the Effective Time Net Working Capital. Any such refund
received by Purchaser, its Affiliates, a Company or Company Subsidiary shall be paid to Sellers, reduced by any Taxes imposed thereon and net of any reasonable costs or expenses incurred by Purchaser or its Affiliates in procuring such refund,
within thirty (30) days after such refund is received. Purchaser agrees to notify Sellers within ten (10) days upon receipt of any such refund. Purchaser shall be entitled to any refund received (whether by payment, credit, offset or
otherwise, and together with any interest thereon), with respect to or relating to any of the Companies or Wholly-Owned Subsidiaries, other than those to which Sellers are entitled pursuant to this Section 8.7. 

Section 8.8. No Duplication. Notwithstanding anything to the contrary in this Article 8, (i) Sellers shall
not have any liability for, and shall not be required to pay to Purchaser, any amounts pursuant to this Article 8 in respect of any Taxes to the extent such Taxes were taken into account in determining the Effective Time Net Working Capital
and (ii) Purchaser shall not have any liability for, and shall not be required to pay to Sellers, any amounts pursuant to this Article 8 in respect of any Taxes to the extent such Taxes were taken into account in determining any
adjustments to the Unadjusted Purchase Price described in Section 2.3, in each case, as ultimately determined pursuant to Article 2. 
 Section 8.9. Cooperation. 
 (a) Each Party shall provide the
other Party with such cooperation and information as it reasonably may request with respect to the Companies and Wholly-Owned Subsidiaries in filing any Tax Return, amended Tax Return or claim for refund, determining a liability for Taxes or a right
to a refund of Taxes or participating in or conducting any audit or other proceeding in respect of Taxes. Each Party shall bear its own expenses in complying with the foregoing provisions. 

(b) Purchaser and Sellers further agree, upon request, to use their reasonable efforts to obtain any certificate or other document from
any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the transactions contemplated hereby).

(ii) New EPE formed El Paso EPE Merger Company, a Delaware corporation (“Merger EPE”), (iii) Merger EPE merged with and into EP Energy Corporation with EP Energy Corporation surviving (and shares of EP Energy Corporation

entity for United States federal Tax purposes and corresponding state income Tax laws, (v) El Paso Exploration & Production Management, Inc., a Delaware corporation, converted into a Delaware limited liability company and became a
disregarded entity for United States federal Tax purposes and corresponding state income Tax laws (referred to in this Agreement as “EP E&P Management”), (vi) MBOW Four Star Corporation, a Delaware corporation, converted
into a Delaware limited liability company and became a disregarded entity for United States federal Tax purposes and 

  
 87 









 
corresponding state income Tax laws, (vii) El Paso Preferred Holdings Company, a Delaware corporation, converted into a Delaware limited liability company and became a disregarded entity for
United States federal Tax purposes and corresponding state income Tax laws (“EP Preferred Holding LLC”), (viii) EP Preferred Holdings LLC distributed its preferred shares in EP Production International Cayman Company and EP
Egypt to EPE LLC, (ix) EPE LLC distributed its common and preferred shares in EP Production International Cayman Company and EP Egypt and distributed all intercompany receivables associated with the Brazil and Egypt projects to New EPE (as
further described on Schedule 3.5) and (x) EP Brazil, each of the BrazilCos and each of the EgyptCos (other than EP Egypt) has previously made a check-the-box election to be a disregarded entity for United States federal Tax purposes.

 (b) Accordingly, the Parties intend for the United States federal Tax purposes and for relevant state income Tax purposes,
(i) EPE LLC and each of its United States Wholly-Owned Subsidiaries that is classified as a corporation for United States federal Tax purposes will be treated as completely liquidated in a nontaxable transaction pursuant to Sections 332 and 337
of the Code, (ii) the purchase and sale hereunder of the EPE LLC Membership Interests as a single-member limited liability company will be treated as a taxable sale by New EPE of the assets of EPE LLC and its United States Wholly-Owned
Subsidiaries to Purchaser, and the purchase of such assets by Purchaser from New EPE, for the applicable portion of the Purchase Price and the assumption of liabilities allocable to the EPE LLC Membership Interests, (iii) this Agreement is a
plan of complete liquidation of EPE LLC and each of its United States Wholly-Owned Subsidiaries that is classified as a corporation for United States federal Tax purposes pursuant to Section 332 of the Code, (iv) the purchase and sale
hereunder of the BrazilCos Shares for United States federal income Tax purposes will be treated as a taxable sale by EP Production International Cayman Company (a controlled foreign corporation wholly-owned by New EPE) of the assets of the BrazilCos
and the purchase of such assets by Purchaser from EP Production International Cayman Company for the applicable portion of the Purchase Price and the assumption of liabilities allocable to the BrazilCos Shares and (v) the purchase and sale
hereunder of the EP Egypt Shares for United States federal income tax purposes will be treated as a taxable sale by New EPE of the EP Egypt Shares. 
 (c) The Parties agree not to take any position inconsistent with such intended Tax consequences. 
 Section 8.11. Section 754 Election. The parties agree to cause each subsidiary of a Company or Company Subsidiary that is treated as a partnership for U.S. federal income tax
purposes to make a valid election under Section 754 of the Code for the taxable year which includes the Closing Date. 

Section 8.12. Conflict. In the event of a conflict between the provisions of this Article 8 and any other
provision of this Agreement, this Article 8 shall control. 
 Article 9 

TERMINATION AND AMENDMENT 
 Section 9.1. Termination. This Agreement may be terminated at any time prior to Closing: 
 (i) by the mutual prior written consent of the Parties; 
 (ii) without any
additional action by any Party at the end of the tenth (10th) Business Day following termination of the Kinder Morgan Merger Agreement unless Sellers elect to waive such automatic termination by providing Purchaser with written notice of such
election before the expiration of such ten (10) Business Day period; 

  
 88 









 (iii) by Sellers (other than in the case of a Funding Failure) or Purchaser, by written
notice to Purchaser or Sellers, respectively, if Purchaser or if any Seller, respectively, is in breach of any representation or covenant in this Agreement, which breach would give rise to the failure of a condition set forth in Article 6 to
be satisfied and is incapable of being cured, or is not cured, by such breaching Party within the earlier of (A) thirty (30) days following receipt of written notice from the non-breaching Party of such breach or such longer period
reasonably required to cure such breach and (B) the End Date; 
 (iv) by Sellers or Purchaser, by written notice to the
other Party, if Closing has not occurred on or before the End Date; 
 (v) by Sellers or Purchaser, by written notice to the
other Party, pursuant to the terms of Section 1.7 of Annex 1; or 
 (vi) by Sellers, by written notice to
Purchaser, if a Funding Failure shall have occurred; 
 provided, however, that (A) neither Sellers nor
Purchaser shall be entitled to terminate this Agreement under Section 9.1(iii) or 9.1(iv) if, in the case of Section 9.1(iii), at the time such termination right arises, or, in the case of Section 9.1(iv),
the Closing has failed to occur, in each case, such Party is in breach of any of its representations, warranties or covenants in this Agreement and such breach would give rise to the failure of a condition set forth in Article 6 to be
satisfied and (B) no one Seller may terminate this Agreement pursuant to this Section 9.1 unless all of Sellers terminate this Agreement (and elect to exercise such right to terminate this Agreement). As used in this Agreement, the
term “End Date” means October 1, 2012; provided, however, that if the Marketing Period has commenced prior to the End Date and has not been completed by the End Date, the End Date shall be extended to the third
(3rd) Business Day after the date on which the Marketing Period is completed, and, in the event of such an extension, such date shall be the “End Date” for purposes of the foregoing; provided, further, however,
that, if all of the conditions to Closing set forth in Section 6.1(a), 6.1(b), 6.1(c) and 6.1(d) have been satisfied, and the Closing shall not have occurred as of such time, Purchaser shall have the right to elect
to extend the End Date until the termination date set forth in the Kinder Morgan Merger Agreement (including as such termination date may be further extended thereunder), and in the event of such an execution, such date shall be the “End
Date” for purposes of the foregoing. 
 Section 9.2. Effect of Termination.

 (b) Certain Termination Fees Payable by Purchaser. In the event this Agreement is terminated: 
 (i) by Sellers pursuant to Section 9.1(iii), then Purchaser shall pay, or cause to be paid (x) to Sellers an amount equal to the total Transaction Costs and Expenses incurred by Sellers
and (y) to Kinder Morgan an amount equal to the KM Transaction Costs and Expenses; or 

  
 89 









 (ii) by Sellers pursuant to Section 9.1(vi), then Purchaser shall pay, or cause
to be paid, to Sellers the Purchaser Termination Fee. 
 For the avoidance of doubt, in no event shall Purchaser be required to
pay the amount of any Transaction Costs and Expenses incurred by Sellers, the KM Transaction Costs and Expenses, the amount of the Purchaser Termination Fee, or any amounts under Section 9.2(d) as applicable, on more than one occasion or
be required to pay any amounts under more than one of Sections 9.2(b)(i), 9.2(b)(ii) or 9.2(d). Payment of the amount of any Transaction Costs and Expenses incurred by Sellers, or the amount of the Purchaser Termination Fee, as
applicable, by Purchaser shall be made by wire transfer of same day funds promptly after termination of this Agreement (and, in any event, within five (5) Business Days thereof) to the account or accounts designated by Sellers. 

(c) Certain Termination Fees Payable by Kinder Morgan. In the event this Agreement is terminated: 

(i) pursuant to Section 9.1(ii), then Kinder Morgan shall pay, or cause to be paid, to Purchaser, substantially
simultaneously with such termination, an amount equal to the Seller Termination Fee by wire transfer of same day funds to the account or accounts designated by Purchaser; 
 (ii) by Purchaser pursuant to Section 9.1(iii), then Kinder Morgan shall, jointly and severally, pay, or cause to be paid, to Purchaser an amount equal to the Debt Financing Expenses
plus the total amount of all Transaction Costs and Expenses incurred by Purchaser, by wire transfer of same day funds promptly after termination of this Agreement (and, in any event, within five (5) Business Days thereof) to the account
or accounts designated by Purchaser; 
 (iii) by either Party pursuant to Section 9.1(iv), then, if, at the time of
such termination all of the conditions to Closing set forth in Sections 6.1(a), 6.1(b), 6.1(c) and 6.1(d) have been satisfied and Purchaser stands ready, willing and able to consummate the Closing, then Kinder Morgan
shall pay, or cause to be paid, to Purchaser an amount equal to the Seller Termination Fee by wire transfer of same day funds promptly after termination of this Agreement (and, in any event, within five (5) Business Days thereof) to the account
or accounts designated by Purchaser; or 
 (iv) by either Party pursuant to Section 9.1(v), then Kinder Morgan
shall, jointly and severally, pay, or cause to be paid, to Purchaser an amount equal to the Debt Financing Expenses plus the total Transaction Costs and Expenses incurred by Purchaser, by wire transfer of same day funds promptly after
termination of this Agreement (and, in any event, within five (5) Business Days thereof) to the account or accounts designated by Purchaser. 
 For the avoidance of doubt, in no event shall Kinder Morgan be required to pay the Seller Termination Fee (or, if applicable, the amount of Transaction Costs and Expenses incurred by Purchaser or the Debt
Financing Expenses) or any amounts under Section 9.2(d) on more than one occasion or be required to pay any amounts under more than one of Sections 9.2(c)(i), 9.2(c)(ii), 9.2(c)(iii), 9.2(c)(iv) or
9.2(d).

recover any money damages (including consequential, indirect or punitive damages) in excess of such respective foregoing amounts. 
 (iii) If the amount determined pursuant to Section 9.2(e)(ii) has been paid, then neither Purchaser nor the Purchaser Guarantors (nor any other Purchaser Party) shall have any further

representation made or alleged to have been made in connection herewith or therewith, whether in equity or at Law, in contract, in tort or otherwise, shall, in each case, be limited to an amount equal to (I) in circumstances where a termination
fee under Section 9.2(c) is elected, (A) the amount set forth in Section 9.2(c) plus (B) the amount of all court costs and attorneys’ fees of Purchaser incurred to recover any such amount or (II) in

 (a) From and after Closing,
Purchaser shall indemnify, defend and hold harmless Sellers and their current and former Affiliates (other than the Companies and any Wholly-Owned Subsidiary) and its and their respective officers, directors, employees, shareholders, members,
partners and agents from and against all Damages incurred or suffered by such Persons: 
 (i) caused by or arising out of or
resulting from Purchaser’s breach of any of Purchaser’s covenants or agreements contained in this Agreement; 
 (ii)
caused by or arising out of or resulting from any breach of any representation or warranty made by Purchaser contained in this Agreement or the failure of any representation or warranty made by Purchaser contained in this Agreement to be true and
correct as of the Closing (other than any representation or warranty that refers to a specified date, which need only be true and correct on and as of such specified date); or 

(iii) resulting from Purchaser’s breach of its obligations set forth in Section 5.15(h). 

but excepting in each of clauses (i) and (ii) above, Damages against which any Seller would be required to indemnify Purchaser
under Section 10.1(b) at the time the claim notice is presented by Purchaser. 

  
 92 









 (b) From and after Closing, Sellers shall, jointly and severally, indemnify, defend and
hold harmless Purchaser, its current and former Affiliates (including, for the avoidance of doubt, the Companies and the Company Subsidiaries) and its and their respective officers, directors, employees, shareholders, members, partners and agents
against and from all Damages incurred or suffered by such Persons: 
 (i) caused by or arising out of or resulting from any
Seller’s breach of any of such Seller’s covenants or agreements contained in this Agreement; 
 (ii) caused by or
arising out of or resulting from any breach of any representation or warranty made by any Seller contained in this Agreement (other than the representations and warranties contained in Section 3.10), or the failure of any representation
or warranty made by any Seller (except as they may relate to the representations and warranties contained in Section 3.10) to be true and correct as of the Closing (other than any representation or warranty that refers to a specified
date, which need only be true and correct on and as of such specified date); 
 (iii) with respect to any Excluded Asset;

 (iv) subject to Section 10.4(c), with respect to any consent (other than any Required Consent) referred to in
any Consent Claim Notice received by either Party, any Company, any Company Subsidiary or any of their respective Affiliates on or prior to the date that is nine (9) months after the Closing Date; or 

(v) with respect to the failure of Sellers to obtain any consent from ANP that is necessary or advisable in connection with the
transactions contemplated hereby. 
 Sellers have no obligation to indemnify Purchaser, its current and former Affiliates and
its and their respective officers, directors, employees and agents against and from, and Purchaser hereby waives any claims against, and releases, Sellers from, any liability, loss, cost, expense, claim, award or judgment suffered or incurred by any
EgyptCo, except to the extent any Damages related thereto are suffered or incurred by any Company or any Subsidiary of any Company thereof other than any EgyptCo. 
 (c) Notwithstanding anything to the contrary contained in this Agreement (other than Article 8), from and after Closing, Sellers’ and Purchaser’s exclusive remedy for money damages
against each other with respect to breaches of the representations, warranties, covenants and agreements of the Parties contained in Article 3, Article 4 and Article 5, the affirmations of such representations, warranties,
covenants and agreements contained in the certificates delivered by each Party at Closing pursuant to Section 7.2(b) or Section 7.3(b), as applicable, and any consent referred to in any Consent Claim Notice referred to in
Sections 10.1(a)(iii) and 10.1(b)(iv), is set forth in this Article 10; provided, however, that with respect to a claim for indemnification for the breach of any representation or warranty set forth in Article
3 that resulted from intentional fraud on the part of any Seller (A) the limitation set forth in clause (iv) of the final sentence of the definition of “Damages” shall not be applicable, (B) the limitation on the time
period for asserting an indemnification claim as set forth in Section 10.4(a) shall not be applicable, (C) the limitation set forth in Section 10.4(b) shall not be applicable, (D) the limitation set forth in
Section 10.4(c) shall not be applicable and (E) the limitation set forth in Section 10.4(e) shall not be applicable. Without limiting the generality of the preceding sentence, (i) Purchaser agrees that from and
after Closing its only remedy with respect to any Seller’s breach of its representations, warranties, covenants and agreements set forth in Article 3 and Article 5 shall be the indemnities of Sellers in
Section 10.1(b), as limited by the terms of this Article 10 and (ii) each Seller agrees that from and after the Closing its only remedy with respect to Purchaser’s breach of its representations and warranties, covenants
and agreements set forth in Article 4 and Article 5 shall be the indemnities of Purchaser in Section 10.1(a), as limited by the terms of this Article 10. 

  
 93 









 (d) “Damages” means the amount of any actual liability, loss, cost,
expense, claim, award, judgment, settlement, obligation, damage, injury, Tax, fine, lien, penalty or deficiency incurred or suffered by any Indemnified Person arising out of or resulting from the indemnified matter, whether attributable to personal
injury or death, property damage, Contract claims, torts or otherwise, including reasonable fees and expenses of attorneys, consultants, accountants or other agents and experts reasonably incident to matters indemnified against, and the costs of
investigation and/or monitoring of such matters, and the costs of enforcement of the indemnity. Notwithstanding the foregoing, Purchaser and Sellers shall not be entitled to indemnification under this Section 10.1 for, and Damages shall
not include, (i) Tax Losses; (ii) loss of profits, whether actual or consequential, or other consequential damages suffered by the Party claiming indemnification, or any punitive damages (other than loss of profits, consequential damages
or punitive damages suffered by third Persons for which responsibility is allocated between the Parties); (iii) any liability, loss, cost, expense, claim, award or judgment to the extent resulting from or increased by the actions of any
Indemnified Person after the Closing; (iv) only in the case of claims under Section 10.1(b)(ii) (other than with respect to the Seller Fundamental Representations), any liability, loss, cost, expense, claim, award, judgment,
settlement, obligation, damage, injury, Tax, fine, lien, penalty or deficiency that does not individually exceed $1,000,000 (less any amount in respect of any individual item that is incurred as described in Section 2.3(g) in
connection with curing or attempting to cure the applicable breach of representation of warranty) and (v) any effects of a breach of representation or warranty in this Agreement that have been cured at the time of Closing for which there is no
continuing Damage. 
 (e) Any claim for indemnity under this Section 10.1 by any current or former Affiliate,
director, officer, employee or agent must be brought and administered by the applicable Party to this Agreement. No Indemnified Person other than Sellers and Purchaser shall have any rights against any Seller or Purchaser under the terms of this
Section 10.1 except as may be exercised on its behalf by Purchaser or Sellers, as applicable, pursuant to this Section 10.1(e). Each of Sellers and Purchaser may elect to exercise or not exercise indemnification rights under
this Section 10.1(e) on behalf of the other Indemnified Persons affiliated with it in its sole discretion and shall have no liability to any such other Indemnified Person for any action or inaction under this Section 10.1(e).

 (f) The conduct of any environmental investigation, material remediation or other response action (and communication or
negotiation with any Governmental Authority regarding same) with respect to any claimed Damages under this Section 10.1 or relating to a breach of Sellers’ representation or warranty pursuant to Section 3.11 or any Claim
relating to the subject matter of such representation or warranty shall be subject to the following: 
 (i) Sellers and
Purchaser agree that no environmental investigation, material remediation or other response action with respect to any claimed Damages shall be undertaken unless required by Environmental Laws, a Governmental Authority, a Contract in effect as of
the Closing or as otherwise agreed to by the Parties; 
 (ii) Sellers and Purchaser agree to take all reasonable actions to
avoid and minimize damages that would otherwise be subject to indemnification under this Section 10.1, including not causing, soliciting or importuning any Governmental Authority to require any environmental action, investigation,
monitoring or remediation not required by Environmental Laws; 
 (iii) From and following the Closing, Purchaser shall not
conduct (or have conducted on its behalf) any environmental investigation, material remediation or other response action 

  
 94 









 
that includes invasive testing or could reasonably be expected to result in a claim for damages without first giving Sellers notice of such action with reasonable detail at least thirty
(30) days prior thereto (or such shorter period of time as shall be required by any Governmental Authority or as may be necessary to address an emergency that Purchaser in good faith believes presents a reasonably likelihood of material
property damage and/or any risk to human health of safety). Sellers shall have the option to observe such investigation, remediation, or response operations. With respect to any investigation, remediation or other response action subject to the
provisions of this Section 10.1(f), Purchaser agrees to provide Sellers with copies of all reports submitted to the overseeing Governmental Authority and all results of sampling and analysis activities after such results have been
subject to reasonable quality assurance and quality control; provided, however, that, with respect to any samples taken, Purchaser shall take split samples and provide one of such samples, properly labeled and identified, to Sellers
free of charge. 
 (iv) Any remediation activities undertaken with respect to the assets of the E&P Business for which any
Seller may have responsibility shall be reasonable in extent and cost effective and shall be designed or implemented in such a manner as to achieve the least stringent risk-based closure or remediation standard applicable to the property in question
under Environmental Laws, subject to the approval of any Governmental Authority with jurisdiction over such remediation activities, and to the extent either Party has legal capacity to do so, Purchaser and the applicable Seller agree to impose
reasonable environmental deed or use restrictions that reduce the cost of any such remediation activities; provided, however, that nothing in this Section 10.1(f)(iv) shall be construed to require a closure or remediation
standard that would pose an ongoing risk or hazard to any operator or occupant of the affected property, that would violate the terms of any existing agreement pertaining to the property, or that would cause Purchaser to be subject to a materially
increased risk of a claim by a third-party for Damages; and 
 (v) No Indemnifying Person shall have any obligation to
indemnify any Indemnified Person under this Section 10.1 for any Damages constituting costs of any remedial, removal or other response action taken in order to meet a more stringent cleanup standard (in comparison to the standard in
effect as of the Closing Date) triggered by a change by any Indemnified Person in land use from such use in effect as of the Closing Date (unless such change in use was required by any agreement in effect as of the Closing Date), or from a change in
applicable Environmental Law after the Closing Date. In connection with any remedial, removal or other response action required in connection with any such change in use not already required as of the Closing Date, the Indemnifying Person shall be
responsible for Damages to achieve the original standard in effect as of the Closing Date and the Indemnified Person shall be responsible for all incremental additional Damages, if any, necessary to achieve the more stringent standard. 

(g) After becoming aware of any fact, event, circumstance or condition that has given rise to or would reasonably be expected to give
rise to any Damages, the Indemnified Persons shall use commercially reasonable efforts to mitigate damages, for which efforts such Indemnified Persons are entitled or may be entitled to indemnification under this Section 10.1. In
connection with each Indemnified Person’s obligation to use commercially reasonable efforts to mitigate Damages, none of the Parties shall knowingly or intentionally take any action that would be expected to provoke a Governmental Authority or
other Person to take any action that would materially exacerbate any damages, taking into consideration the situation as a whole. 
 (h) The Parties shall treat, for Tax purposes, any amounts paid under Article 8 or this Article 10 as an adjustment to the Purchase Price, which adjustment shall be reflected in the Share
Unadjusted Purchase Price Allocation and applicable Asset Unadjusted Purchase Price Allocation(s) in the same manner as provided in Section 2.2. 

  
 95 









 Section 10.2. Indemnification Actions. All claims for indemnification
under Section 10.1 shall be asserted and resolved as follows: 
 (a) For purposes of this Article 10, the
term “Indemnifying Person” when used in connection with particular Damages means the Person having an obligation to indemnify another Person or Persons with respect to such Damages pursuant to this Article 10 and the term
“Indemnified Person” when used in connection with particular Damages means a Person having the right to be indemnified with respect to such Damages pursuant to this Article 10 (including those Persons identified in
Section 10.1(e)). 
 (b) To make a claim for indemnification under Section 10.1, an Indemnified Person
shall notify the Indemnifying Person of its claim, including the reasonably specific details of and reasonably 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 Person against the Indemnified Person (a “Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Claim and shall enclose a
copy of all papers (if any) served with respect to the Claim; provided that the failure of any Indemnified Person to give notice of a Claim as provided in this Section 10.2 shall not relieve the Indemnifying Person of its
obligations under Section 10.1 except to the extent such failure actually prejudices the Indemnifying Person’s ability to defend against the 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 shall specify the representation, warranty, covenant or agreement that was inaccurate or breached. 

(c) In the case of a claim for indemnification based upon a Claim, the Indemnifying Person shall have thirty (30) days from its
receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies its obligation to defend the Indemnified Person against such Claim under this Article 10. The Indemnified Person may, during such thirty (30) day
period and upon ten (10) days prior written notice to the Indemnifying Person, file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Person and that is not
prejudicial to the Indemnifying Person. 
 (d) If the Indemnifying Person admits its obligation, it shall have the right and
obligation to defend, at its sole cost and expense, and with counsel reasonably satisfactory to the Indemnified Person, the Claim. The Indemnifying Person shall have full control of such defense and proceedings, including any compromise or
settlement thereof (subject to the penultimate sentence of this Section 10.2(d)) and, in the event the Indemnified Person settles any claim over the objection of the Indemnifying Person, the Indemnified Person shall be deemed to have
waived any right to indemnity therefor. If requested by the Indemnifying Person, the Indemnified Person agrees to reasonably cooperate, at the Indemnifying Person’s sole cost and expense, in contesting any Claim which the Indemnifying Person
elects to contest (provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person). The Indemnified Person may participate in, but not control, any defense or
settlement of any Claim controlled by the Indemnifying Person pursuant to this Section 10.2(d). Notwithstanding an Indemnifying Person’s election to assume the defense of a Claim, the Indemnified Person shall have the right to
employ separate counsel and to participate in the defense of such Claim, and the Indemnifying Person shall bear the reasonable fees, costs and expenses of such separate counsel if: (i) the use of such counsel chosen by the Indemnifying Person
to represent the Indemnified Person would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such claim include both the Indemnifying Person and the Indemnified Person, and the
Indemnified Person shall have reasonably concluded that there may be legal defenses available to it which are different from or additional to those available to the Indemnifying Person (in which case the Indemnifying Person shall not have the right
to assume the defense of such claim on the 

  
 96 









 
Indemnified Person’s behalf); (iii) the Indemnifying Person shall not have employed counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person within
a reasonable time after notice of the institution of such claim or (iv) the Indemnifying Person shall authorize the Indemnified Party to employ separate counsel at the Indemnifying Party’s expense. An Indemnifying Person shall not, without
the written consent of the Indemnified Person, settle any Claim or consent to the entry of any judgment with respect thereto that (i) does not result in a final resolution of the Indemnified Person’s liability with respect to the Claim
(including, in the case of a settlement, an unconditional written release of the Indemnified Person from all further liability in respect of such Claim) or (ii) provides for relief other than monetary damages that are to be paid in full by the
Indemnifying Person or (iii) includes or contains a finding or admission of any violation of Law or has any effect on any other Claims that may be made against the Indemnified Person. In the event an Indemnifying Party assumes the defense of a
claim, such Indemnifying Party shall defend such claim vigorously and in good faith. 
 (e) If the Indemnifying Person does not
admit its obligation or admits its obligation but fails to defend or settle the Claim, then the Indemnified Person shall have the right to defend against the Claim (at the sole cost and expense of the Indemnifying Person, if the Indemnified Person
is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of the Indemnifying Person to admit its obligation to indemnify the Indemnified Person and assume the defense of the Claim at any
time prior to settlement or final determination thereof. If the Indemnifying Person has not yet admitted its obligation to indemnify the Indemnified Person, the Indemnified Person shall send written notice to the Indemnifying Person of any proposed
settlement and the Indemnifying Person shall have the option for ten (10) days following receipt of such notice to (i) admit in writing its obligation for indemnification with respect to such Claim and (ii) if its obligation is so
admitted, assume the defense of the Claim, including the power to reject and accept the obligation with respect to the proposed settlement. If the Indemnified Person settles any Claim over the objection of the Indemnifying Person after the
Indemnifying Person has timely admitted its obligation for indemnification in writing and assumed (and continues) the defense of the Claim, the Indemnified Person shall be deemed to have waived any right to indemnity therefor. 

(f) In the case of a claim for indemnification not based upon a Claim, the Indemnifying Person shall have thirty (30) days from its
receipt of the Claim Notice to (i) fully cure the Damages complained of, if such Damages are capable of being fully cured within such period, (ii) admit its obligation to provide indemnification with respect to such Damages or
(iii) dispute the claim for such Damages. If the Indemnifying Person does not notify the Indemnified Person within such thirty (30) day period that it has fully cured the Damages or that it disputes the claim for such Damages, the
Indemnifying Person shall be conclusively deemed obligated to provide indemnification hereunder. 
 Section 10.3.
Casualty and Condemnation. If, after the Execution Date but prior to the Closing Date, any portion of the assets of the E&P Business is destroyed or damaged by fire or other casualty or is expropriated or taken in condemnation or
under right of eminent domain, Purchaser shall nevertheless be required to comply with the covenants in Article 7 and attend the Closing if all conditions to Closing set forth in Section 6.2 are satisfied. In the event of any such
casualty or taking after the Execution Date but prior to the Closing Date, the applicable Seller shall cause to be transferred to the applicable Company or Wholly-Owned Subsidiary all sums paid to such Seller or its Affiliates (other than the
Companies or their Wholly-Owned Subsidiaries) by third Persons by reason of the casualty or taking of such assets of the E&P Business, including any sums paid pursuant to any policy or agreement of insurance or indemnity, and shall assign,
transfer and set over unto such Company or Wholly-Owned Subsidiary all of the rights, title and interest of Sellers or its Affiliates (other than the Companies or their Wholly-Owned Subsidiaries) in and to any claims, causes of action, unpaid
proceeds or other payments from third Persons, including any policy or agreement of insurance or indemnity, arising out of such casualty or taking. 

  
 97 









 Section 10.4. Limitation on Actions. 

(a) The right to assert an indemnification claim pursuant to Section 10.1 with respect to the representations and warranties
of Sellers and Purchaser in Article 3 and Article 4 and the corresponding representations and warranties given in the certificates delivered at Closing pursuant to Section 7.2(b) or Section 7.3(b), as
applicable, shall survive the Closing for twelve (12) months except that (i) the right to assert an indemnification claim pursuant to Section 10.1 with respect to Seller Fundamental Representations or the Purchaser Fundamental
Representations, as applicable, shall survive the Closing without time limit and (ii) there shall be no post-Closing right to indemnification pursuant to Section 10.1 with respect to the diminution or loss of value in the EgyptCos
or the EP Egypt Shares arising as a result of a breach of the representations and warranties of Sellers relating to the EP Egypt Shares or E&P Business of the EgyptCos. The right to assert an indemnification claim pursuant to
Section 10.1 for the breach of (x) covenants requiring performance on or prior to the Closing shall survive the Closing for twelve (12) months and (y) covenants requiring performance after the Closing shall survive the
Closing for twelve (12) months following the date on which any such covenant expires in accordance with its terms or after the applicable statute of limitations period, if shorter. 

Representations, warranties, covenants and agreements shall be of no further force and effect after the date of the expiration of a right
to assert an indemnification claim with respect thereto, provided that there shall be no termination of any claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to the
applicable expiration date. 
 (b) The indemnities in Section 10.1(a)(i), Section 10.1(a)(ii),
Section 10.1(b)(i) and Section 10.1(b)(ii) shall terminate as of the termination 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 Person on or before such termination date. The indemnities in Sections 10.1(a)(iii) and 10.1(b)(iv) shall survive the Closing for a period of nine
(9) months, except with respect to any Damages with respect to any of the consents referred to in any Consent Claim Notice received by any Party, any Company or any Company Subsidiary prior to the date that is nine (9) months after the
Closing Date, with respect to which such indemnities shall survive until such matters are fully and finally resolved. Section 10.1(b)(v) shall survive the Closing without time limit. 

(c) No Seller shall have any liability for any indemnification under Section 10.1(b)(ii) (other than with respect to the
Seller Fundamental Representations) until and unless the aggregate amount of the liability for all Damages for which Claim Notices are delivered by Purchaser exceed two percent (2.0%) of the Unadjusted Purchase Price, and then only to the
extent such Damages exceed two percent (2.0%) of the Unadjusted Purchase Price. Sellers shall be required to bear (and indemnify Purchaser from and against) (i) fifty percent (50%) of each dollar of any Damages attributable to a claim
for indemnity pursuant to Section 10.1(b)(iv) until the total amount of such Damages exceeds $15,000,000, in the aggregate and (ii) one hundred percent (100%) of any Damages suffered or incurred by the Companies and/or the
Company Subsidiaries and attributable to claims for indemnity pursuant to Section 10.1(b)(iv) after the Companies and/or the Company Subsidiaries have suffered or incurred an amount equal to $7,500,000 with respect to such Damages.

 (d) No Seller shall have any liability for any Brazil Tax Loss until and unless the aggregate amount of the liability for
all Brazil Tax Losses exceeds $15,000,000, and then only to the extent such aggregate amount exceeds $15,000,000. 
 (e)
Notwithstanding anything to the contrary contained elsewhere in this Agreement, no Seller shall be required to indemnify Purchaser under Section 10.1(b)(ii) (other than with respect to the Seller Fundamental Representations and the
indemnity in Section 10.1(b)(iv)) for aggregate Damages in excess of ten percent (10%) of the Unadjusted Purchase Price. 

  
 98 









 (f) For purposes of determining Damages subject to indemnification pursuant to this
Article 10 (but not, for the avoidance of doubt, for purposes of determining whether any representation and warranty has been breached or is true and correct, other than the representations and warranties set forth in Section 3.5
(No Undisclosed Liabilities) and Section 3.12 (Compliance with Laws, but solely to the extent arising out of or related to compliance with Laws that are in existence on the Execution Date), in each case, for which the
representations and warranties contained therein shall be deemed to have been made, for purposes of indemnification pursuant to this Article 10, without any qualifications as to materiality, Material Adverse Effect, specified dollar
thresholds or similar qualifications for purposes of determining whether any such representation or warranty has been breached or is true and correct), the representations and warranties contained in this Agreement shall be deemed to have been made
without any qualifications as to materiality, Material Adverse Effect, specified dollar thresholds or similar qualifications; provided, however, that for purposes of determining whether a representation or warranty in
Section 3.6 (Labor Matters), Section 3.7 (Employee Benefits), Section 3.9 (Litigation), Section 3.11 (Environmental Laws) or Section 3.19 (Assets of the
E&P Business) has been breached or is true and correct as of the Closing for purposes of indemnification pursuant to this Article 10, any reference in such representation or warranty to “Material Adverse Effect” shall
instead be deemed to be a reference to an adverse effect on the E&P Business or the ownership, assets, operations or financial condition of the Company and Company Subsidiaries, taken as a whole, that would result in Damages of at least
$62,500,000; provided, further, however, that for purposes of determining whether a representation or warranty in Section 3.8 (Accuracy of Data) has been breached or is true and correct as of the Closing for
purposes of indemnification pursuant to this Article 10, any reference in such representation or warranty to “Material Adverse Effect” shall instead be deemed to be a reference to an adverse effect on the E&P Business or the
ownership, assets, operations or financial condition of the Company and Company Subsidiaries, taken as a whole, that would result in Damages of at least $25,000,000. 
 (g) The amount of any Damages for which an Indemnified Person is entitled to indemnity under this Article 10 shall be reduced by the amount of insurance proceeds actually realized by the
Indemnified Person or its Affiliates with respect to such Damages (net of any collection costs and associated premium increases, and excluding the proceeds of any insurance policy issued or underwritten by the Indemnified Person or its Affiliates,
any retrospective insurance policies and any captive insurance policies). In the event that an Indemnified Person is entitled to any insurance, indemnification or other recovery from any third Person with respect to any Damages for which such
Indemnified Person seeks indemnification, such Indemnified Person shall use commercially reasonable efforts to obtain any such indemnification or recovery, as the case may be. In the event that any insurance proceeds or other amounts from any third
Person are actually recovered or realized by an Indemnified Person subsequent to receipt by such Indemnified Person of any indemnification payment hereunder in respect of the claims to which such insurance proceeds or other amounts relate, a portion
of such indemnification payment equal to the net amounts so recovered or realized shall promptly be refunded to the Indemnifying Person.

of any exemption from sales, use, real property transfer or any other Transfer Taxes that is based wholly or partially on facts and information related to Sellers, including, providing Purchaser and taxing authorities access to books and records
establishing the lack of prior similar sales activity and the ability of a particular Seller to separately establish income and expenses attributable to assets being transferred to Purchaser. 

Section 11.4. Expenses. Except as provided in Section 5.6, Section 5.19 and
Section 11.3, all expenses incurred by Sellers (or by any Company or Wholly-Owned Subsidiary) in connection with or related to the authorization, preparation or execution of this Agreement, and the Exhibits and Schedules hereto and

shall be borne solely and entirely by Purchaser. 
 Section 11.5. Company Records. 

(a) As soon as reasonably practicable after the Closing Date, each Seller shall deliver or cause to be delivered to Purchaser any
Company Records that are in its possession (or under its control), subject to Section 11.5(b). 
 (b) Sellers may
retain the Excluded Company Records and the originals of those Company Records relating to Tax and accounting matters and provide Purchaser with copies of such Company Records that pertain to (i) Non-Income Tax matters solely related to the
Companies or (ii) non-unitary state Income Tax Returns to the extent such Tax Returns are reasonably necessary to satisfy Purchaser’s Tax Return filing obligations under Section 8.2. Sellers may retain copies of any other

thereafter, Purchaser shall make the filings required in each Company’s and Wholly-Owned Subsidiary’s jurisdiction of organization to eliminate the name “El Paso” and any variant thereof from the name of each Company and
Wholly-Owned Subsidiary. As promptly as practicable, but in any case within two hundred and seventy (270) days after the Closing Date, Purchaser shall (i) make all other filings (including assumed name filings) required to reflect the
change of name in all applicable records of Governmental Authorities and (ii) use commercially reasonable efforts to eliminate the use of the name “El Paso” and any variant thereof from the assets of the E&P Business and the
E&P Business, and, except with respect to such grace period for eliminating existing usage, shall have no right to use any logos, trademarks or trade names belonging to any Seller or any of its Affiliates. Purchaser shall be solely responsible
for any direct or indirect costs or expenses resulting from the change in use of name, and any resulting notification or approval requirements. Notwithstanding anything to the contrary set forth in this Section 11.6, the use by Purchaser
and its Affiliates (which for the avoidance of doubt shall include any Company and any Company Subsidiary) of “EP Resources” or “EP Energy” shall not be restricted hereunder. 

Section 11.7. Governing Law. THIS AGREEMENT AND THE LEGAL RELATIONS BETWEEN THE PARTIES (INCLUDING ANY CLAIMS MADE IN
CONTRACT, TORT OR OTHERWISE RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY) SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS THAT WOULD

court within the State of Delaware). Each Party consents to personal jurisdiction in any action brought in the Delaware Court of Chancery (or, if jurisdiction is not available in the Delaware Court of Chancery, to personal jurisdiction in any action
brought in the state or federal courts located in the State of Delaware) with respect to any dispute, claim or controversy arising out of or in relation to or in connection with this Agreement (including any claims made in Contract, tort or
otherwise relating to this Agreement or the transactions contemplated hereby), and each of the Parties agrees that any action instituted by it against the other with respect to any such dispute, controversy or claim (except to the extent a dispute,
controversy, or claim arising out of or in relation to or in connection with the allocation of the Purchase Price pursuant to Section 2.2(b) or the determination of the final Purchase Price pursuant to Section 2.4(b) is
referred to an expert pursuant to those Sections and subject to the provisions of Annex 1) will be instituted exclusively in the Delaware Court of Chancery (or, if jurisdiction is not available in the Delaware Court of Chancery, then
exclusively in the state or federal courts located in the State of Delaware). The Parties hereby waive trial by jury in any action, proceeding or counterclaim brought by any Party against another in any matter whatsoever arising out of or in
relation to or in connection with this Agreement. 
 (b) Limitation on Suits Against Financing Providers.
Notwithstanding anything herein to the contrary, each of the Parties agrees that it will not bring or support any action, cause of action, claim, cross-claim or third-party claim of any kind or description, whether in Law or in


  
 102









 
equity, whether in contract or in tort or otherwise, against the Equity Providers or the Debt Providers and their respective current, former or future directors, officers, general or limited
partners, stockholders, members, managers, controlling persons, Affiliates, employees or Representatives in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including any dispute arising out of or
relating in any way to the Financing Letters or the performance thereof, in any forum other than the Supreme Court of the State of New York, County of New York, or, if under applicable law exclusive jurisdiction is vested in the federal courts, the
United States District Court for the Southern District of New York (and appellate courts thereof). Each of the Parties irrevocably agrees to waive trial by jury in any action, cause of action, claim, cross-claim or third-party claim referred to
in this paragraph.  
 (c) Notwithstanding anything herein to the contrary, Sellers shall be entitled to specific
performance to cause Purchaser to draw down the Equity Financing or to consummate the Closing only if: 
 (i) all conditions in
Section 6.2 (other than those conditions that by their nature are to be satisfied at the Closing, but subject to those conditions being capable of being satisfied) have been satisfied; 

(ii) Purchaser has failed to complete the Closing by the date the Closing is required to occur pursuant to Section 7.1;

 (iii) the Debt Financing has been funded or is expected to be funded at the Closing if the Equity Financing is funded at the
Closing (provided, that Purchaser shall not be required to draw down the Equity Financing or to consummate the Closing if the Debt Financing is not in fact funded at the Closing); and 

(iv) Sellers have irrevocably confirmed in writing to Purchaser that if specific performance is granted and the Equity Financing and
Debt Financing are funded, then the Closing will occur. 
 (d) Notwithstanding anything herein to the contrary, Sellers shall
be entitled to specific performance to cause Purchaser to draw down the Debt Financing (or any Alternate Financing) only if the Closing will occur substantially simultaneously with such draw down. 

Section 11.9. Captions. The captions in this Agreement are for convenience only and shall not be considered a part of
or affect the construction or interpretation of any provision of this Agreement. 
 Section 11.10. Waivers.
Any failure by any Party to comply with any of its obligations, agreements or conditions herein contained may be waived by the Party to whom such compliance is owed by an instrument signed by the Party to whom compliance is owed and expressly
identified as a waiver, but not in any other manner. No waiver of, or consent to a change in, any of the provisions of this Agreement shall be deemed or shall constitute a waiver of, or consent to a change in, other provisions hereof (whether or not
similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided. 
 Section 11.11.
Assignment. No Party shall assign or otherwise transfer all or any part of this Agreement, nor shall any Party delegate any of its rights or duties hereunder, without the prior written consent of the other Party and any transfer or
delegation made without such consent shall be void; provided, however, that each Party shall have the right to assign its rights under this Agreement to any of its Affiliates or as collateral to any lender (or agent or trustee
therefor) in connection with any bona fide financing arrangement, including in the case of Purchaser the Debt Financing; provided, further, however, 

  
 103









 
that no such assignment shall relieve such Party of its obligations hereunder in the event of the failure of performance by such assignee. Subject to the foregoing, this Agreement shall be
binding upon and inure to the benefit of the Parties and their respective successors and assigns. 
 Section 11.12.
Entire Agreement. The Confidentiality Agreement, this Agreement and the documents to be executed hereunder (including the Transition Services Agreement, the Lease and the Personal Property Assignment) and the Exhibits and Schedules
attached hereto constitute the entire agreement among the Parties pertaining to the subject matter hereof, and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties pertaining to the
subject matter hereof. 
 Section 11.13. Amendment. This Agreement may be amended or modified only by an
agreement in writing signed by Sellers and Purchaser and expressly identified as an amendment or modification. 

Section 11.14. No Third-Person Beneficiaries. Nothing in this Agreement shall entitle any Person other than Purchaser
and Sellers to any claim, cause of action, remedy or right of any kind, except the rights expressly provided to the Persons described in Section 5.17, Section 9.2 and Section 11.20 and except that the Debt
Providers and their respective current, former or future directors, officers, general or limited partners, stockholders, members, managers, controlling persons, Affiliates, employees or Representatives shall be third party beneficiaries of
Sections 9.2, 11.7, 11.8(a), 11.8(b), 11.8(d) and this Section 11.14. 

Section 11.15. Guarantees. Simultaneously with execution of this Agreement, (i) Purchaser has caused those
certain entities party thereto (the “Purchaser Guarantors”) to deliver to Sellers guarantees each in substantially the form attached hereto as Exhibit A (each a “Parent Guarantee”) and (ii) Sellers
have caused El Paso (the “El Paso Guarantor”) to deliver to Purchaser a guarantee in substantially the form attached hereto as Exhibit B (the “El Paso Guarantee”). 

Section 11.16. Headings. Headings have been provided for the sections of this Agreement, the Schedules and Exhibits
for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement. 

Section 11.17. References. In this Agreement: 

(a) references to any gender includes a reference to all other genders; 

(b) references to the singular includes the plural, and vice versa;

 104

 Section 11.18. Construction. Purchaser is capable of making such
investigation, inspection, review and evaluation of the assets of the E&P Business as a prudent purchaser would deem appropriate under the circumstances, including with respect to all matters relating to the assets of the E&P Business and
their value, operation and suitability. Each of Sellers and Purchaser has had the opportunity to exercise business discretion in relation to the negotiation of the details of the transaction contemplated hereby. This Agreement is the result of
arm’s-length negotiations from equal bargaining positions. It is expressly agreed that this Agreement shall not be construed against any Party, and no consideration shall be given or presumption made, on the basis of who drafted this Agreement
or any particular provision thereof; it being further understood and agreed that nothing in this Section 11.18 shall limit any representation, warranty, covenant or indemnity contained herein or in any certificate delivered pursuant
hereto. 
 Section 11.19. Time of Essence. This Agreement contains a number of dates and times by which
performance or the exercise of rights is due, and the Parties intend that each and every such date and time be the firm and final date and time, as agreed. For this reason, each Party hereby waives and relinquishes any right it might otherwise have
to challenge its failure to meet any performance or rights election date applicable to it on the basis that its late action constitutes substantial performance, to require the other Party to show prejudice, or on any equitable grounds. Without
limiting the foregoing, time is of the essence in this Agreement. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any
action taken expires on a date which is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day which
is a Business Day.

any member, partner or stockholder of any of the Covered Persons, shall have any liability (whether in contract or in tort) for any obligations or liabilities arising under, in connection with or related to this Agreement or for any claim based on,
in respect of, or by reason of, the transactions contemplated hereby; provided, however, that nothing in this Section 11.20 shall limit (i) any liability of the Parties for breaches of this Agreement, (ii) any
liability of the Purchaser Guarantors provided for in the Parent Guarantee or (iii) any liability of the El Paso Guarantor provided for in the El Paso Guarantee.

Closing (it being understood and agreed that any breach of such representation or warranty shall be subject to the Title Threshold and Title Deductible as though such breach constituted a Title Defect with respect to the applicable Title Asset);

 (vi) defects arising solely out of lack of survey, overlapping survey, or lack of metes and bounds descriptions, unless one
is required by Law; 
 (vii) defects that have been cured by applicable Laws of limitations or prescription, including adverse
possession, the doctrine of laches, and deemed marketable record title; 
 (viii) defects arising from any change in applicable
Laws after the Execution Date; 
 (ix) defects arising from prior expired oil and gas leases that are not surrendered or
released of record; 
 (x) defects with respect to which the true owner of the applicable Company Property is another Company
or Company Subsidiary; 

  
 Annex 1 - 3









 (xi) defects based on Purchaser’s change (or desired change) in the surface or bottom
hole location, borehole or drainhole path, well or operational plan, operational technique (including completion or stimulation technique) of any Title Asset; 
 (xii) defects arising out of production payments that have expired of their own terms; 
 (xiii) defects based on a claim that none of the Companies or the Company Subsidiaries has title to a Company Property (other than a Reserve Asset), if any of the Companies or the Company Subsidiaries has
a valid right to use such Company Property for the purposes for which it is being used; 
 (xiv) defects based solely on
Sellers’ failure to have a title insurance policy or survey on any Company Property; 
 (xv) defects based upon an
Impaired Reserve Asset to the extent the basis on which such defect is asserted is any defect or deficiency with respect to the Major Midstream Assets; and 
 (xvi) defects arising out of mortgages or liens that are unenforceable under applicable statutes of limitations. 
 (d) The Parties acknowledge and agree that any reference in this Annex 1 to the net revenue interest of any Michigan Undeveloped Lease as set forth in Exhibit C-1, Part 2 shall be a
reference to a percentage (expressed as a decimal) equal to the product of (i) one hundred percent (100%) minus the sum (expressed as a percentage) of the amounts set forth in the “Royalty Burden” column and “ORRI
Burden” column on Exhibit C-1, Part 2 for such Michigan Undeveloped Lease, as applicable, multiplied by (ii) a fraction, the numerator of which is the number set forth in the “NET AC” column in Exhibit
C-1, Part 2 for such Michigan Undeveloped Lease and the denominator of which is the number set forth in the “GR AC” column in Exhibit C-1, Part 2 for such Michigan Undeveloped Lease. 

Section 1.3 Definition of Permitted Encumbrances. As used in this Annex 1, the term “Permitted
Encumbrances” means any or all of the following: 
 (a) all Lessors’ royalties and any overriding royalties,
reversionary interests, net profits interests, production payments and other burdens to the extent that they do not, individually or in the aggregate, reduce the applicable net revenue interest in any Reserve Asset below that shown in Exhibit

(ii) that would be accepted by a reasonably prudent purchaser engaged in the business of owning and operating oil and gas properties similar to the Company Properties. 
 Section 1.4 Allocated Values. The “Allocated Value” for (a) any Well shall be equal to the portion of the Unadjusted Purchase Price allocated to such Well on Exhibit
C-1, Part 1 and (b) for each Michigan Undeveloped Lease shall be equal to the number of Net Mineral Acres covered by such Lease as set forth in Exhibit C-1, Part 2, multiplied by $300. Sellers have accepted such
Allocated Values for purposes of this Annex 1, but make no representation or warranty as to the accuracy of such value. 

Section 1.5 Notice of Title Defects; Defect Adjustments. 

(a) To assert a Title Defect, Purchaser must deliver a claim notice or notices to Sellers with respect thereto on or before the date that
is seventy-five (75) days following the Execution Date (the “Title Claim Date”); provided that Purchaser agrees to use reasonable efforts to provide Sellers with periodic (but in no event less frequently than once every
two (2) weeks) updates in writing concerning the progress of Purchaser’s title due diligence. Each notice of Title Defect shall be in writing and shall include (each such notice, a “Title Defect Notice”): 

(i) a reasonably detailed description of the alleged Title Defect(s); 

(ii) the Title Asset(s) affected; 
 (iii) the Allocated Values of the Title Asset(s) subject to or affected by the alleged Title Defect(s); and 

  
 Annex 1 - 6









 (iv) the amount by which Purchaser reasonably believes the Allocated Values of those Title
Assets are reduced by the alleged Title Defect(s) and the computations and information upon which Purchaser’s belief is based. 
 Purchaser shall provide Sellers documentation available to Purchaser supporting Purchaser’s asserted Title Defect(s). Purchaser shall be deemed to have waived all defects in title to the Company
Properties (other than as described in Section 1.1 of this Annex 1) of which Sellers have not been given written notice from Purchaser on or before the Title Claim Date. 

(b) Should Purchaser discover any Title Benefit on or before the Title Claim Date, Purchaser shall deliver to Sellers on or before the
Title Claim Date a written notice including: 
 (i) a description of the Title Benefit; 

(ii) the Title Asset(s) affected; 
 (iii) the Allocated Values of the Title Asset(s) subject to such Title Benefit; and 
 (iv) the amount by which Purchaser reasonably believes the Allocated Value of those Title Assets is increased by the Title Benefit(s) and the computations and information upon which Purchaser’s
belief is based. 
 Sellers shall have the right, but not the obligation, to deliver to Purchaser an equivalent notice on or before the date
that is the Title Claim Date with respect to each Title Benefit discovered by Sellers. Sellers shall be deemed to have waived all Title Benefits of which no Party has given notice on or before the Title Claim Date, except to the extent Purchaser has
failed to give a written notice which it was obligated to give under this Section 1.5(b). If Sellers deliver such notice to Purchaser, Sellers shall provide Purchaser documentation available to Sellers supporting Sellers’ asserted
Title Benefit(s). 
 (c) Sellers shall have the right, but not the obligation, to attempt, at Sellers’ sole cost, to cure
or remove on or before sixty (60) days after the Closing Date, any Title Defects of which Sellers have been advised by Purchaser. Purchaser shall reasonably cooperate with Sellers in Sellers’ efforts to cure Title Defects during such
period; provided, however that, the Parties agree that the foregoing shall not require Purchaser (or, after Closing, any Company or Company Subsidiary) to incur any costs or expenses (or waive any rights it may have) with respect
thereto. No reduction shall be made in the Unadjusted Purchase Price with respect to a Title Defect for purposes of Closing if Sellers have provided written notice to Purchaser of Sellers’ intent to attempt to cure such Title Defect on or
before the Closing Date. If the Title Defect is not cured as agreed by Sellers and Purchaser or if Sellers and Purchaser cannot agree, and it is determined by the Title Arbitrator that such Title Defect is not cured at the end of the sixty
(60) day post-Closing period, the adjustment to the Unadjusted Purchase Price required under this Annex 1 shall be made pursuant to Section 2.3 of the Agreement. Sellers’ election to attempt to cure a Title Defect
shall not constitute a waiver of Sellers right to dispute the existence, nature or value of, the Title Defect. 
 (d) With
respect to each Title Asset affected by a Title Defect reported under Section 1.5(a), the Unadjusted Purchase Price shall be reduced by an amount (the “Title Defect Amount”) equal to the reduction in the Allocated Value
for such Title Asset(s) caused by such Title Defects, as determined pursuant to Sections 1.5(g) and 1.5(i). Notwithstanding the foregoing provisions of this Section 1.5(d), no adjustment to the Unadjusted Purchase Price
shall be made with respect to any Title Defect that is cured within sixty (60) days after the Closing. 

  
 Annex 1 - 7









 (e) With respect to each Title Asset affected by a Title Benefit reported under
Section 1.5(b) (or which Purchaser should have reported under Section 1.5(b)), the Unadjusted Purchase Price shall be increased by an amount (the “Title Benefit Amount”) equal to the increase in the Allocated
Value for such Title Asset caused by such Title Benefits, as determined pursuant to Sections 1.5(h) and 1.5(i); provided, however that, in no event will the aggregate adjustments to the Unadjusted Purchase Price as a
result of Title Benefits exceed the aggregate adjustments to the Unadjusted Purchase Price due to Title Defects. 
 (f) This
Annex 1, Sections 3.9, 3.10, 3.12, 3.13, 3.14, 3.22 and 3.23 of the Agreement (and the indemnities related thereto), Section 2.3(h) of the Agreement with respect to any of the
matters described therein and Section 5.15 of the Agreement and the indemnity set forth in Section 10.1(b)(iv) of the Agreement, shall be the sole and exclusive right and remedy of Purchaser with respect to any defect in
title with respect to any of the Company Properties; provided, however, that Section 3.22(b) shall be the sole and exclusive right and remedy of Purchaser with respect to the Major Midstream Assets. In this regard and
notwithstanding anything to the contrary in the Agreement, if any Title Defect with respect to any of the Company Properties results from any matter which could also result in the breach of any representation or warranty of a Seller as set forth in
Article 3 of the Agreement (other than Sections 3.9, 3.10, 3.12, 3.13, 3.14, 3.22 and 3.23 of the Agreement), then Purchaser shall only be entitled to assert such matter prior to the Title
Claim Date as a Title Defect to the extent permitted by this Annex 1 and shall be precluded from also asserting such matter as the basis of the breach of any such representation or warranty. Except as provided in this Annex 1 (and
Sections 3.9, 3.10, 3.12, 3.13, 3.14, 3.22 and 3.23 of the Agreement (and the indemnities related thereto), Section 2.3(h) of the Agreement with respect to any of the matters described
therein and Section 5.15 of the Agreement and the indemnity set forth in Section 10.1(b)(iv) of the Agreement), Purchaser releases, remises and forever discharges Sellers and their current and former Affiliates and all such
parties’ stockholders, officers, directors, employees, agents, advisors and representatives from any and all suits, legal or administrative proceedings, claims, demands, damages, losses, costs, liabilities, interest or causes of action
whatsoever, in law or in equity, known or unknown, which Purchaser might now or subsequently may have, based on, relating to or arising out of, any Title Defect, or other deficiency in title with respect to any of the Company Properties. 

(g) The Title Defect Amount (calculated in the case of a Title Defect that affects multiple Title Assets, as a single aggregate amount
for all Title Assets affected thereby and not as a separate amount of each of the individual Title Assets affected thereby) resulting from a Title Defect shall be determined as follows: 

(i) if Purchaser and Sellers agree on the Title Defect Amount, that amount shall be the Title Defect Amount; 

(ii) if the Title Defect is a lien, encumbrance, or other charge which is undisputed and liquidated in amount, then the Title Defect
Amount shall be the amount necessary to be paid to remove the Title Defect from the relevant Company’s or Company Subsidiary’s interest in the affected Title Asset; 
 (iii) if the Title Defect represents a discrepancy between (A) the net revenue interest for any Reserve Asset and (B) the net revenue interest for such Reserve Asset shown in Exhibit C-1,
Part 1 or Exhibit C-1, Part 2, respectively, then the Title Defect Amount shall be the product of the Allocated Value of such Reserve Asset multiplied by a fraction, the numerator of which is such net revenue interest
decrease and the denominator of which is the net revenue interest for such Reserve Asset shown in Exhibit C-1, Part 1 or Exhibit C-1, Part 2, respectively, provided that if the Title Defect does not affect such
Reserve Asset throughout its entire productive life, the Title Defect Amount determined under this Section 1.5(g)(iii) shall be reduced to take into account the applicable time period only; 

  
 Annex 1 - 8









 (iv) if the Title Defect results from the failure of any of the Companies or the Company
Subsidiaries to have title to the number of Net Mineral Acres set forth in the “Net Ac” column in Exhibit C-1, Part 2 for any Michigan Undeveloped Lease, then the Title Defect Amount shall be $300 per Net Mineral Acre
multiplied by the amount of such Net Mineral Acre shortfall; 
 (v) if the Title Defect represents an obligation,
encumbrance, burden or charge upon or other defect in title to the affected Title Asset of a type not described in subsections (i), (ii), (iii) or (iv) above, then the Title Defect Amount shall be determined by taking into account the
Allocated Value of the Title Asset(s) so affected, the portion of the relevant Company’s or Company Subsidiary’s interest in the Title Asset(s) affected by the Title Defect, the legal effect of the Title Defect, the potential economic
effect of the Title Defect over the life of the affected Title Asset or Title Assets, the age of the factual matters causing or constituting the alleged Title Defect, and such other factors as are necessary to make a proper evaluation; 

(vi) notwithstanding anything to the contrary in this Annex 1, (A) a claim for a Title Defect for which notice is given
prior to the Title Claim Date shall only generate an adjustment to the Unadjusted Purchase Price if the Title Defect Amount (calculated in the case of a Title Defect that affects multiple Title Assets, as a single aggregate amount for all Title
Assets affected thereby and not as a separate amount for each Title Asset affected thereby) with respect thereto exceeds $1,000,000 (the “Title Threshold”), (B) the aggregate Title Defect Amounts attributable to the effects of
all Title Defects upon any given Title Asset shall not exceed the Allocated Value of such Title Asset (it being understood that in the case of a Title Defect affecting multiple Title Assets, the Title Defect Amount will be allocated among affected
Title Assets in a fair and equitable manner) and (C) there shall be no adjustment to the Unadjusted Purchase Price for Title Defects unless and until the aggregate amount of all Title Defect Amounts for which an adjustment to the Unadjusted
Purchase Price would be permitted pursuant to Section 1.5(g)(vi)(A) exceeds $85,000,000 (the “Title Deductible”), and then only to the extent that such aggregate amount of all such Title Defect Amounts exceeds the Title
Deductible; 
 (vii) if the Title Defect affects an Other Real Property Interest and the loss of such Other Real Property
Interest will materially and adversely affect the development, operation or production of one or more Reserve Assets (each an “Impaired Reserve Asset”), then such Title Defect shall be considered to affect the applicable Impaired
Reserve Assets and the Title Defect Amount shall take into account the decrease in the Allocated Value for the applicable Impaired Reserve Assets; and 
 (viii) without limitation of Purchaser’s right to aggregate all Title Defect Amounts attributable to the same Title Defect for purposes of determining if the Title Threshold has been met with respect
to such Title Defect, the Title Defect Amount with respect to a Title Defect shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder, or for which Purchaser otherwise receives credit in the
calculation of the Purchase Price. 
 (h) The Title Benefit Amount for any Title Benefit shall be: (i) in the case of a
Title Benefit affecting any Title Asset, the product of the Allocated Value of the affected Title Asset multiplied by a fraction, the numerator of which is the net revenue interest increase and the denominator of which is the applicable net revenue
interest in such Title Asset shown in Exhibit C-1, Part 1 or Exhibit C-1, Part 2, respectively and (ii) in the case of a Title Benefit affecting a Michigan Undeveloped Lease, $300 multiplied by the amount of
the increase in the number of Net Mineral Acres for such Michigan Undeveloped Lease above the number of Net Mineral Acres set forth for such Michigan Undeveloped Lease in Exhibit C-1, Part 2, provided that, in each case above,
(x) if a Title Benefit affects multiple Title 

  
 Annex 1 - 9









 
Assets, then the Title Benefit Amount shall be calculated as a single aggregate amount for all Title Assets affected thereby and not as a separate amount for each Title Asset affected thereby and
(y) if the Title Benefit does not affect a Title Asset throughout the entire life of the Title Asset, then the Title Benefit Amount determined under this Section 1.5(h) shall be reduced to take into account the applicable time
period only. Notwithstanding anything to the contrary in this Annex 1, an individual claim for a Title Benefit which is reported under Section 1.5(b) (or which Purchaser should have reported under Section 1.5(b)) prior
to the Title Claim Date shall only generate an adjustment to the Unadjusted Purchase Price if the aggregate of all Title Benefit Amounts with respect to all Title Assets affected thereby exceeds the Title Threshold. 

(i) Sellers and Purchaser shall attempt to agree on all (i) Title Defects, Title Benefits, Title Defect Amounts and Title Benefit
Amounts within thirty (30) days after the Title Claim Date and (ii) Alleged Required Consents within thirty (30) days after the delivery of the Consent Notice with respect thereto (which such thirty (30) day period, for the
avoidance of doubt, shall be inclusive of the ten (10) Business Day period described in Section 5.15(c) of the Agreement). The Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts that Sellers and Purchaser
are unable to agree with respect to by such date, and all Required Consent Disputes submitted to arbitration pursuant to Section 5.15(d) of the Agreement, shall be exclusively and finally resolved by arbitration pursuant to this
Section 1.5(i), and, if the Closing Date occurs prior to the final resolution of any such matters, then, to the extent such unresolved matters relate to a Title Defect, Title Benefit, Title Defect Amount or Title Benefit Amount,
Sellers’ good faith estimate shall be used to determine the Closing Payment pursuant to Section 2.4(a) of the Agreement. During the ten (10) day period following the expiration of the applicable thirty (30) day period, all
Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts in dispute, or, if applicable, all Required Consent Disputes, shall be submitted (a) with respect to any disputes regarding Title Defects, Title Benefits, Title
Defect Amounts or Title Benefit Amounts, to a title attorney with at least ten (10) years’ experience in oil and gas titles in the state or other jurisdiction in which the Title Assets with the largest aggregate Allocated Value of all of
the Title Assets in question are located (provided, however, for this purpose, the Title Assets located in the United States outer continental shelf shall be deemed to be located in the state adjacent to which the applicable Title
Assets are located, determined pursuant to the currently-existing administrative boundaries for the Gulf of Mexico Region of the Outer Continental Shelf published by the Bureau of Ocean Energy Management), as selected by mutual agreement of
Purchaser and Sellers or absent such agreement during the ten (10) day period, by the Houston office of the American Arbitration Association or (b) with respect to any Required Consent Dispute, to a title attorney with at least ten
(10) years’ experience in oil and gas titles as selected by mutual agreement of Purchaser and Sellers or absent such agreement during the ten (10) day period, by the Houston office of the American Arbitration Association (each title
attorney selected with respect to each of the foregoing described disputes, a “Title Arbitrator”). Likewise, if by the end of the sixty (60) day post-Closing cure period under Section 1.5(c), Sellers have failed to
cure any Title Defects which it provided notice prior to Closing that it would attempt to cure, and Sellers and Purchaser have been unable to agree on the Title Defect Amounts for such Title Defects, the Title Defect Amounts in dispute shall be
submitted to the applicable Title Arbitrator. No Title Arbitrator shall have worked as an employee or outside counsel for either Party or its Affiliates during the five (5) year period preceding the arbitration or have any financial interest in
the dispute. In connection with the engagement of a Title Arbitrator, each of Sellers and Purchaser shall execute such engagement, indemnity and other agreements as such Title Arbitrator shall require as a condition to such engagement. The
arbitration proceeding shall be held in Houston, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this
Section 1.5(i). Each Title Arbitrator’s determination shall be made within forty-five (45) days after submission of the matters in dispute and shall be final and binding upon the Parties, without right of appeal. In making his
determination, each Title Arbitrator shall be bound by (y) with respect to any disputes regarding Title Defects, Title Benefits, Title Defect Amounts or Title Benefit Amounts, the rules 

  
 Annex 1 - 10









 
set forth in this Annex 1 and (z) with respect to any Required Consent Dispute, the provisions of Section 5.15 of the Agreement, and, in each case, may consider such other
matters as in the opinion of such Title Arbitrator are necessary or helpful to make a proper determination. Additionally, each Title Arbitrator may consult with and engage disinterested third Persons to advise the arbitrator, including title
attorneys from other states and petroleum engineers. Each Title Arbitrator shall act as an expert for the limited purpose of determining the specified disputed matters submitted to it pursuant to this Section 1.5(i) (or, with respect to
any Required Consent Dispute, pursuant to Section 5.15 of the Agreement) and, except in the case of any Required Consent Dispute, may not award damages, interest or penalties to any Party with respect to any matter. Sellers and Purchaser
shall each bear its own legal fees and other costs of presenting its case to a Title Arbitrator. Purchaser shall bear one-half of the costs and expenses of each Title Arbitrator, and Sellers shall be responsible for the remaining one-half of the
costs and expenses of each Title Arbitrator. Notwithstanding anything to the contrary set forth herein (or in the Agreement), (1) if any lawsuit, arbitration or other proceeding with respect to any Required Consent is pending at the time such
Required Consent becomes the subject of a Required Consent Dispute or (2) if during the determination by any Title Arbitrator of any Required Consent Dispute the Required Consent that is the subject matter of such Required Consent Dispute
becomes the subject matter of any lawsuit, arbitration or other proceeding, then, the provisions of this Section 1.5(i) shall, in the situation described in clause (1), not apply to such Required Consent Dispute and, in the situation
described in clause (2), immediately cease to apply to such Required Consent Dispute, in each case, until such time as such lawsuit, arbitration or other proceeding is finally determined. 

Section 1.6 Limitations on Applicability. The right of Purchaser or Sellers to assert a Title Defect or Title Benefit,
respectively, under this Agreement shall terminate on the Title Claim Date; provided there shall be no termination of Purchaser’s or Sellers’ rights under Section 1.5 with respect to any bona fide Title Defect or Title
Benefit claim properly reported on or before the Title Claim Date (or which should have been reported by Sellers or Purchaser pursuant to Sections 1.5(a) or 1.5(b), respectively). 

Section 1.7 Termination. The Agreement, including this Annex 1, may be terminated prior to Closing by either
Purchaser or Sellers, upon written notice to the other Party, in the event that the sum of the Title Defect Amounts properly asserted by Purchaser in good faith less the sum of all Title Benefit Amounts, after giving effect to the Title
Threshold and the Title Deductible, as may be applicable thereto, equal or exceed fifteen percent (15%) of the Unadjusted Purchase Price.
