2.Purchase and Sale; Purchase Price. At the Closing, and upon the terms and subject to the conditions of this Agreement, the Seller agrees to sell and convey to the Buyer all of its Properties, and the Buyer agrees to purchase, accept and pay for the Properties and to assume all of the Assumed Obligations. In consideration for the sale of the Properties, the Buyer will pay to the Seller the purchase price of FIVE BILLION THREE HUNDRED SEVENTY-FIVE MILLION DOLLARS ($5,375,000,000.00) (the “Purchase Price”, subject to adjustments as provided in this Agreement) in immediately available funds at Closing (pursuant to wire transfer instructions designated in advance by the Seller to the Buyer in writing). Within two (2) Business Days after the Execution Date, the Buyer will pay to the Seller an earnest money deposit equal to five percent (5%) of the unadjusted Purchase Price (the “Deposit”). At Closing, the Deposit will be applied against the Purchase Price payable to the Seller in accordance with the provisions of this Agreement. The Purchase Price will be adjusted (without duplication) as set forth below in this Section 2.

2.1. Title and Environmental Defects. The Purchase Price will be (a) decreased only for those uncured Title Defects and uncured Environmental Defects that are in excess of the respective Individual Defect Thresholds and the Aggregate Defect Threshold and (b) increased for Title Benefits, in each case, in accordance with this Section 2.1. The Buyer may deliver to the Seller, on or before the Defect Notice Date, one or more written notices specifying each defect associated with the Seller’s Properties that the Buyer asserts constitutes a Title Defect or an Environmental Defect, a specific description of each such Title Defect or Environmental Defect and the basis for such assertion under the terms of this Agreement, the amount of the adjustment to the Purchase Price that the Buyer asserts based on such Title Defect or Environmental Defect and its method of calculating such adjustment, together with all data and information reasonably necessary for the Seller to verify the existence of the alleged Title Defect or

PURCHASE AND SALE AGREEMENT 19

Environmental Defect (“Defect Notice”). The term “Defect Notice Date” means (i) 5:00 p.m. Central Time on the one hundred twentieth (120^th) day following the Closing Date in the case of Title Defects and (ii) 5:00 p.m. Central Time on the fifth (5^th) Business Day prior to the Closing Date in the case of Environmental Defects. Any matters that may otherwise constitute Title Defects or Environmental Defects, but of which the Seller has not been notified by the Buyer in writing by the respective Defect Notice Date, shall be deemed to have been waived by the Buyer for all purposes; provided, however, that no failure to provide any such notice by the respective Defect Notice Date shall be deemed a waiver of any right or remedy under the Assignment with respect to any breach of the special warranty of title to be given by the Seller in the Assignment. All adjustments to the Purchase Price based on Title Defects will be based on the Allocated Values attributable to the affected Properties. Upon timely delivery of a Defect Notice under this Section 2.1, the Buyer and the Seller will in good faith negotiate the validity of the claim and the amount of any adjustment to the Purchase Price using the following criteria:

2.1.1 No single Title Defect or Title Benefit shall be taken into account unless the value of such defect or benefit is determined to be more than (i) Twenty-Five Thousand Dollars ($25,000) with respect to any Well or (ii) Fifteen Thousand Dollars ($15,000) with respect to any Real Property Interest, and no single Environmental Defect shall be taken into account unless the value of such defect is determined to be more than Fifty Thousand Dollars ($50,000) (each an “Individual Defect Threshold”).

2.1.2 No adjustment will be made to the Purchase Price for either uncured Title Defects or for uncured Environmental Defects unless the total of all individual adjustments for such Title Defects and Environmental Defects that exceed the respective Individual Defect Thresholds exceeds one and one-tenth (1.1%) of the unadjusted Purchase Price in the aggregate (the “Aggregate Defect Threshold”) after first offsetting any Title Benefits. In the event that the total of all such individual adjustments for uncured Title Defects and uncured Environmental Defects exceeds the Aggregate Defect Threshold, the adjustment to the Purchase Price shall only be for the amount by which the total of all such individual adjustments for uncured Title Defects and uncured Environmental Defects exceeds the Aggregate Defect Threshold plus the total value of all individual adjustments for any Title Benefits. In no event will the aggregate amount of Title Defect adjustments with respect to a Property exceed the Allocated Value of such Property. With respect to any Title Defects or Environmental Defects for which an adjustment equal to the entire Allocated Value of the affected Property is made to the Purchase Price hereunder, at the Seller’s option, as a condition precedent to such adjustment, the Buyer will execute and deliver to the Seller an assignment (in substantially the same form as the Assignment) of such Property.

PURCHASE AND SALE AGREEMENT 20

2.1.3 If the adjustment is based on the Seller owning an NRI in a Real Property Interest or Well which is less than that shown on Exhibit A, then the downward adjustment with respect to such Property shall be calculated by multiplying the Allocated Value shown for such Property on Exhibit A by a fraction, the numerator of which is an amount equal to the NRI shown for such Property on Exhibit A less the NRI to which the Seller is actually entitled taking such Title Defect into account, and the denominator of which is the NRI shown for such Property on Exhibit A.

2.1.4 If the adjustment is based on the Seller owning a Working Interest in a Well which is larger than the Working Interest shown for such Property on Exhibit A, but without a proportionate increase in the NRI for such Property, then the downward adjustment shall be calculated by determining the effective NRI that results from such larger Working Interest, determining what the NRI would be using such effective NRI and the Working Interest shown for such Property on Exhibit A and then calculating the adjustment in the manner set forth in Section 2.1.3.

2.1.5 If the adjustment is based on the Seller owning fewer Net Acres in a Real Property Interest than those shown for such Real Property Interest on Exhibit A, then the downward adjustment shall be calculated by multiplying the Allocated Value shown for such Property on Exhibit A by a fraction, the numerator of which is the number of Net Acres shown for such Property on Exhibit A minus the actual Net Acres actually owned in such Property, and the denominator of which is the number of Net Acres shown for such Property on Exhibit A.

2.1.6 If the adjustment is based on a Lien upon the Seller’s Real Property Interest or Well that is liquidated in amount, then the downward adjustment is the lesser of the amount necessary to remove such Lien from such Property or the Allocated Value of such Property.

2.1.7 If the adjustment is based on an Early Lease Expiration, then the downward adjustment shall be calculated by multiplying the Allocated Value shown for such Real Property Interest on Exhibit A by a fraction, (a) the numerator of which is (i) the lesser of 547 days and the number of days within the period beginning on the Effective Time and ending on the expiration date of the Real Property Interest as set forth on Exhibit A, minus (ii) the number of days within the period beginning on the Effective Time and ending on the actual expiration date of the Real Property Interest as set forth in the applicable lease, and (b) the denominator of which is the lesser of 547 days and number of days within the period beginning on the Effective Time and ending on the expiration date of the Real Property Interest as set forth on Exhibit A. Alternatively, if an adjustment is based on a Late Lease Expiration, then the upward adjustment shall be calculated by multiplying the Allocated Value shown for such Real Property Interest on Exhibit A by a fraction, (a) the numerator of which is (i) the lesser of

PURCHASE AND SALE AGREEMENT 21

547 days and the number of days within the period beginning on the Effective Time and ending on the actual expiration date of the Real Property Interest as set forth in the applicable lease, minus (ii) the number of days within the period beginning on the Effective Time and ending on the expiration date of the Real Property Interest as set forth on Exhibit A, and (b) the denominator of which is the number of days within the period beginning on the Effective Time and ending on the expiration date of the Real Property Interest as set forth on Exhibit A; provided, however, no adjustment based on a Late Lease Expiration shall exceed an amount equal to the Allocated Value shown for the respective Real Property Interest on Exhibit A.

2.1.8 If the adjustment is based on a liability to remediate or otherwise cure an Environmental Defect related to a Real Property Interest, then the downward adjustment with respect to such Property is that portion of the amount necessary to implement and complete any remedial, removal, response, construction, closure, disposal or other corrective actions, or monitoring required under Environmental Laws to correct or remove such Environmental Defect in the most cost effective manner reasonably available and consistent with common industry practices for which the Buyer would be liable after Closing.

2.1.9 If the Seller determines that a Real Property Interest is subject to a Late Lease Expiration or that its ownership of (a) any Well entitles the Seller to a larger NRI or a smaller Working Interest (without a proportionately smaller NRI) than that shown for such Property on Exhibit A or (b) any Real Property Interest entitles the Seller to a larger NRI or a greater number of Net Acres than that shown for such Property on Exhibit A (each, a “Title Benefit”), then the Seller shall notify the Buyer of such Title Benefit in writing on or before the Defect Notice Date for Title Defects, which notice shall include a reasonably detailed description of such Title Benefit, the Dollar value that the Seller asserts is attributable to such Title Benefit and the Seller’s method of calculating such amount. The Seller shall be deemed to have conclusively waived any Title Benefits of which it fails to notify the Buyer in the manner and by the date specified in the preceding sentence. The upward adjustment to the Purchase Price in respect of each Title Benefit shall be determined using the same principles as provided in this Section 2.1 with respect to Title Defects. For the avoidance of doubt, a single matter shall be treated as a single Title Benefit even if affecting more than one Property.

2.1.10 If a Title Defect or an Environmental Defect is reasonably susceptible of being cured, then the Seller will have the right to cure such defect for a period of up to sixty (60) days after the respective Defect Notice Date (such period for Title Defects and such period for Environmental Defects, the respective “Cure Period”). The Buyer shall provide the Seller and its representatives access to the Properties and the Records after Closing in

PURCHASE AND SALE AGREEMENT 22

connection with the Seller’s efforts to cure alleged defects. The Seller will be deemed to have adequately completed the cure of an Environmental Defect after the implementation and completion of any remedial, removal, response, construction, closure, disposal or other corrective actions required under Environmental Laws to correct or remove such Environmental Defect.

2.1.11 If after the respective Cure Period the Seller and the Buyer are not in agreement as to (a) whether a Defect Notice or notice of Title Benefit complies with the terms hereof, (b) the existence of or value attributable to a Title Defect, Title Benefit or Environmental Defect, (c) whether a Title Defect or Environmental Defect has been cured during the respective Cure Period, or (d) the amount of any adjustments to be made to the Purchase Price in respect of any uncured Title Defect, Title Benefit or uncured Environmental Defect, then the Seller and the Buyer will submit the dispute to arbitration as provided in this Section following written notice from one Party to the other Party on or before the date thirty (30) days after the end of the respective Cure Period that such Party is initiating dispute resolution in accordance with this Section, such notice to describe in reasonable detail the nature and specifics of the dispute. The Buyer, with respect to Environmental Defects, shall be deemed to have conclusively waived any unresolved Environmental Defect, or cure thereof, which is not submitted for resolution as provided in this Section on or before the date one hundred twenty (120) days after the end of the Cure Period applicable to Environmental Defects. The Buyer, with respect to Title Defects, and the Seller, with respect to Title Benefits, shall be deemed to have conclusively waived any unresolved Title Defect, or cure thereof, or any unresolved Title Benefit which is not submitted for resolution as provided in this Section on or before the date one hundred twenty (120) days after the end of the Cure Period applicable to Title Defects. The matter to be arbitrated shall be submitted to a title attorney licensed to practice in the state in which the applicable Property is located selected by the Seller and the Buyer, in the case of a Title Defect or Title Benefit, or to an environmental expert in the state in which the applicable Property is located selected by the Seller and the Buyer, in the case of an Environmental Defect (each such title attorney or environmental expert hereinafter, a “Consultant”). If the Seller and the Buyer are unable to agree on any Consultant within thirty (30) days after receipt of the initiating notice, then the Seller on the one hand and the Buyer on the other hand will each appoint one Consultant within ten (10) days thereafter and the two Consultants so appointed will appoint a third Consultant within ten (10) days after the second Consultant is appointed, and the three Consultants so appointed will resolve such matter. The cost of each Consultant shall be paid fifty percent (50%) by the Seller and fifty percent (50%) by the Buyer. The Seller and the Buyer shall each present to the Consultant(s), with a simultaneous copy to the other Party, a single written statement of its position on the defect or benefit in question,

PURCHASE AND SALE AGREEMENT 23

together with a copy of this Agreement and any supporting material that such Party desires to furnish, not later than the fifth (5th) Business Day after appointment of the Consultant(s). In making their determination, the Consultant(s) shall be bound by the terms of this Agreement and, without any additional or supplemental submittals by either Party, may consider available legal and industry matters as in their opinion are necessary or appropriate to make a proper determination. By the twentieth (20th) day following the submission of the matter to the Consultant(s), applying the principles set forth in this Section 2.1, the Consultant(s) shall make a determination of the matter submitted. The decision of the Consultant(s) shall be in writing and conclusive and binding on the Seller and the Buyer and shall be enforceable against the Parties in any court of competent jurisdiction. The Consultant(s) shall act as experts for the limited purpose of determining the specific title or environmental dispute presented to them, shall not act as arbitrators, may not hear or decide any matters except the specific title or environmental disputes presented to them and may not award damages, interest, costs or penalties to either Party.

2.1.12 If the Parties have mutually agreed upon (or the Consultant(s) shall have finally determined) the amount of any Purchase Price adjustment required to be made pursuant to the terms of this Section 2.1 in respect of a Title Benefit or in respect of an Title Defect or Environmental Defect that the Seller have elected not to cure or that otherwise remains uncured after expiration of the respective Cure Period, in each case, (a) prior to the date the Closing Statement is initially delivered by the Seller to the Buyer pursuant to Section 2.7, then such amount will be included in the Purchase Price adjustments to be made at Closing in accordance with the Closing Statement, or (b) after the foregoing date but prior to the date the Final Statement is initially delivered by the Seller to the Buyer pursuant to Section 2.8, then such amount will be included in the Purchase Price adjustments to be made after Closing in accordance with the Final Statement, or (c) after both such dates, then such amount will be paid after the Closing in accordance with Section 2.9.

2.2. Preferential Purchase Rights; Required Consents. Within ten (10) Business Days (two (2) Business Days in the case of SUSA) after the Execution Date, the Seller shall provide any required notifications of a preferential purchase right, right of first refusal or other agreement which gives a Third Party a right to purchase a Real Property Interest or Well (or any part thereof) (“PPR”), requesting waivers thereof, in connection with the transactions contemplated hereby and otherwise in material compliance with the contractual provisions applicable to such PPR. Within ten (10) Business Days (two (2) Business Days in the case of SUSA) after the Execution Date, the Seller will send letters seeking (a) the SUSA consents, agreements and waivers described in Sections 6.4 and 7.5 and (b) all applicable Required Consents, excluding Customary Post-Closing Consents. The Seller will thereafter use commercially reasonable efforts (at no cost to the Seller) to ensure

PURCHASE AND SALE AGREEMENT 24

that all such waivers and consents are promptly granted, and after Closing, the Buyer will reasonably assist the Seller in obtaining any remaining waivers and consents.

2.2.1 If, as of the Closing Date, (i) a holder of a PPR has notified the Seller that it elects to exercise its PPR with respect to the Properties (or portions thereof) to which its PPR applies (determined by and in accordance with the agreement under which the PPR arises), or (ii) no waiver, consent or exercise notice has been received by the Seller from the holder of a PPR but the time for exercising such PPR has not expired, then in each such case the Properties (or portions thereof) covered by the applicable PPR will not be sold to the Buyer (subject to the remaining provisions in this Section 2.2), and the Purchase Price will be reduced by the Allocated Value of the Properties (or portions thereof) subject to such PPR. If, as of the Closing Date, a holder of a Required Consent has not yet delivered such Required Consent, then the Properties (or portions thereof) covered by that Required Consent (i) will not be conveyed to the Buyer at Closing but shall still be considered part of the Properties in accordance with the provisions of Section 2.2.2, (ii) adjustments to the Purchase Price will still be made pursuant to Sections 2.5 and 2.6 with respect to such Property, and (iii) the Purchase Price will not be reduced as a result of such non-conveyance.

2.2.2 If Properties (or portions thereof) have been excluded from the Properties sold to the Buyer at the Closing (i) due to a pre-Closing exercise of a PPR, and if for any reason the purchase and sale of such Properties is not or cannot be consummated with the holder of such PPR that exercised such PPR and the Seller is thereby permitted to transfer such Properties (or portions thereof) to the Buyer pursuant to the terms of such PPR, or (ii) due to the Seller having not received a waiver, consent or exercise notice from the holder of a PPR and the time for exercising such PPR had not expired as of the Closing Date, and if the Seller subsequently receives such a waiver or consent, or if the Seller does not receive an exercise notice from the holder of the PPR with in the period for exercising such PPR, then in each such case the Seller shall so notify the Buyer and, within ten (10) Business Days after the Buyer’s receipt of such notice, the Seller shall sell, assign, and convey to the Buyer and the Buyer shall purchase and accept from the Seller such Properties pursuant to the terms of this Agreement and for the Allocated Value of such Properties, subject to adjustments in accordance with Sections 2.5 and 2.6. If Properties (or portions thereof) have been excluded from the Properties conveyed to the Buyer at the Closing due to the Seller having not received a Required Consent as of the Closing Date in accordance with Section 2.2.1, and if the Required Consent has been received or deemed received pursuant to the terms of the underlying agreement on or before the one (1) year anniversary of the Closing Date, then in each such case the Seller shall so notify the Buyer and, within ten (10) Business Days after the Buyer’s

PURCHASE AND SALE AGREEMENT 25

receipt of such notice, the Seller shall assign and convey to the Buyer and the Buyer shall accept from the Seller such Properties pursuant to the terms of this Agreement. As between the Buyer and the Seller, with respect to any Property for which a Required Consent has not been obtained by the Closing, (a) the Seller shall hold such Property as nominee for the Buyer, effective as of the Effective Time, (b) the Buyer shall pay any costs and expenses associated with that Property, and (c) the Seller shall pay the Buyer any revenues received by the Seller that are associated with such Property for time periods from and after the Effective Time. If any Required Consent has not been received or deemed received on or before the one (1) year anniversary of the Closing Date, then the Seller shall no longer hold such Property as nominee for the Buyer, and each Party shall repay to the other Party any amounts previously paid hereunder in respect of the Property, and such Property will be deemed not to have been conveyed to the Buyer hereunder and shall be an Excluded Asset. From the Closing until the date of conveyance (or until the one year anniversary, if not to be conveyed pursuant to this Section 2.2.2 due to expiration of such period), with respect to those Properties not conveyed at Closing solely pursuant to Section 2.2.1 and which Seller continues thereafter to operate, Seller will continue to conduct its operations with respect to such Properties consistent with the provisions of Section 5.2, subject to the caveats and liability limitations contained therein.

2.2.3 Properties excluded pursuant to this Section 2.2 will not be deemed to be affected by Title Defects or be subject to Section 2.1.

2.3. Gas Imbalances. The Purchase Price will be adjusted upward or downward, as applicable, by (a) the net mcf amount of the Seller’s aggregate wellhead gas imbalances as of the Effective Time multiplied by $2.75 per mcf (upward for underage and downward for overage); and (b) the mmbtu amount of any pipeline imbalances or unsatisfied throughput obligations attributable to the Seller or the Properties as of the Effective Time multiplied by $2.75 per mmbtu (upward for over deliveries and downward for under deliveries).

2.4. Casualty Loss. If, after the Execution Date but prior to the Closing Date, any portion of the Properties is damaged, destroyed or taken by condemnation or eminent domain or suffers a reduction in value as a result of a Casualty (a “Casualty Loss”), the Buyer will nevertheless be required to close and the Purchase Price will be adjusted in an amount equal to the lesser of (a) the Allocated Value of the Property affected by such Casualty Loss or (b) the amount of such Casualty Loss.

2.5. Certain Upward Adjustments. The Purchase Price shall be increased by the following (without duplication): (a) the value of all merchantable allowable oil or other liquid Hydrocarbons in storage above the pipeline connection at the Effective Time that is credited to the Properties in accordance with gauging and other customary industry procedures, such value to be the current market price at

PURCHASE AND SALE AGREEMENT 26

the Effective Time, less taxes and gravity adjustments deducted by the purchaser of such oil or other liquid Hydrocarbons; (b) the amount of all expenditures incurred and paid by or on behalf of the Seller in connection with the ownership, operation and maintenance of the Properties (including rentals, overhead, royalties, prepayments, operating, drilling and completion costs and other charges and expenses billed under applicable operating agreements) attributable to the period on or after the Effective Time, excluding any such amounts to cure or remediate any Title Defect or Environmental Defect; (c) all expenses of the type referenced in (b) paid by or on behalf of the Seller in connection with unleased interests and incurred subsequent to the Effective Time; (d) the amount of any proceeds from the sale of Hydrocarbons produced prior to the Effective Time from the Properties that are received by Buyer on behalf of the unleased interests; and (e) any other amount agreed upon by the Buyer and the Seller, or otherwise required to be reflected pursuant to the other provisions of this Section 2.

2.6. Certain Downward Adjustments. The Purchase Price shall be decreased by the following (without duplication): (a) the amount of any proceeds actually received by the Seller from the sale of Hydrocarbons produced from and after the Effective Time from the Properties (net of royalties and other burdens, and production, severance, sales, use and similar Taxes measured by or payable out of production; provided, that on oil the amount shall be the amount paid by the purchaser to the Seller) net of marketing fees; (b) the amount equal to all unpaid ad valorem, property, production, severance and similar Taxes (excluding income, capital gains, franchise or similar Taxes) based upon or measured by the ownership of the Properties or the production of Hydrocarbons therefrom or the receipt of proceeds attributable thereto, which accrue to or are chargeable against the Properties in accordance with GAAP prior to the Effective Time, which amount shall, to the extent not actually assessed or known, be computed based upon such Taxes for the immediately preceding calendar year, or, if such Taxes are assessed on other than a calendar year basis, for the Tax period last ended; (c) the amount of all unpaid costs and expenditures in connection with the ownership, operation and maintenance of the Properties (including rentals, overhead, royalties, prepayments, operating, drilling and completion costs and other charges and expenses billed under applicable operating agreements) attributable to periods prior to the Effective Time and that are subsequently paid by or on behalf of Buyer; (d) the amount of any proceeds of the type referenced in (a) attributable to periods after the Effective Time received by Seller on behalf of the unleased interests; (e) all expenses of the type referenced in (c) paid by or on behalf of the Buyer in connection with unleased interests and incurred prior to the Effective Time; and (f) any other amount agreed upon by the Buyer and the Seller, or otherwise required to be reflected pursuant to the other provisions of this Section 2.

2.7. Closing Date Estimates. On or before three (3) Business Days prior to the Closing Date, the Seller (with the cooperation of the Buyer) will prepare, in accordance with the provisions of this Agreement, and deliver to the Buyer a statement (the “Closing Statement”) setting forth each adjustment to the

PURCHASE AND SALE AGREEMENT 27

Purchase Price required under this Agreement (except as otherwise set forth in Section 2.1.12) and showing the calculation of such adjustments. The Closing Statement will be used to adjust the Purchase Price at Closing. Any final adjustments, if necessary, will be made pursuant to Section 2.8 of this Agreement.

2.8. Final Accounting. On or before one hundred twenty (120) days after the Closing Date, the Seller (with the cooperation of the Buyer) will prepare, in accordance with the provisions of this Agreement, and deliver to the Buyer, a post-closing statement setting forth a detailed calculation of all final adjustments to the Purchase Price which takes into account all such adjustments provided in this Agreement (except as otherwise set forth in Section 2.1.12) (the “Final Statement”). If the Buyer disputes any items in or the accuracy and completeness of the Final Statement, then as soon as reasonably practicable, but in no event later than fifteen (15) days after its receipt of the Final Statement, the Buyer will deliver to the Seller a written exception report containing any changes the Buyer proposes to be made to the Final Statement. If the Buyer fails to deliver such exception report to the Seller within that period, the Final Statement as delivered by the Seller will be deemed to be true and correct, binding upon and not subject to dispute by any Party. If the Buyer delivers a timely exception report, as soon as reasonably practicable, but in no event later than thirty (30) days after the Seller receives the Buyer’s exception report, the Parties will meet and undertake to agree on the final post-Closing adjustments to the Purchase Price. If the Parties fail to agree on the final post-Closing adjustments within sixty (60) days after the Seller’s receipt of the Buyer’s exception report, any Party will be entitled to submit the dispute for resolution by the Accounting Referee. The cost of the Accounting Referee shall be paid fifty percent (50%) by the Seller and fifty percent (50%) by the Buyer. The Seller and the Buyer shall each present to the Accounting Referee, with a simultaneous copy to the other Party, a single written statement of its position on the dispute in question, together with a copy of this Agreement, the Closing Statement, the proposed Final Statement, and the Buyer’s written exception report and any supporting material that such Party desires to furnish, not later than ten (10) Business Days after appointment of the Accounting Referee. In making its determination, the Accounting Referee shall be bound by the terms of this Agreement and, without any additional or supplemental submittals by either Party, may consider such other accounting and financial standards matters as in its opinion are necessary or appropriate to make a proper determination. The Parties shall direct the Accounting Referee to resolve the disputes within thirty (30) days after receipt of the written statements submitted for review and to render a decision in writing based upon such written statements. The Accounting Referee shall act as an expert for the limited purpose of determining the specific Final Statement dispute presented to it, shall not act as an arbitrator, shall not consider any other disputes or matters and may not award damages, interest, costs or penalties to either Party. In addition, the Accounting Referee shall agree in writing to keep strictly confidential the specifics and existence of such dispute as well as all proprietary records of the Parties reviewed by the Accounting Referee in the process of resolving such dispute. Upon agreement of the Parties to the adjustments to the

PURCHASE AND SALE AGREEMENT 28

Final Statement, or upon resolution of such adjustments by the Accounting Referee, as the case may be, the Final Statement (as adjusted pursuant to such agreement or resolution by the Accounting Referee) will be deemed final and binding on all of the Parties and the aggregate amount due to either the Buyer or the Seller pursuant to such Final Statement will be paid in accordance with Section 2.9. If any Properties are assigned to Buyer after Closing or re-assigned to Seller in each case pursuant to Section 2.1.2 or 2.2.2, any such finally determined adjustments with respect to the Properties so assigned or re-assigned will be reflected in the amounts paid by Buyer in the event of such an assignment or refunded/unwound in the event of such a re-assignment.

2.9. Payments. Payments to be made following the Closing under this Section 2 shall be made (i) except as otherwise set forth in Section 2.1.12, within five (5) Business Days after the final determination is made that such payments are due and payable and (ii) by wire transfer of immediately available funds (pursuant to wire transfer instructions designated in advance by the receiving Party to the paying Party writing) for the account of the receiving Party.

2.10. Administration of Unleased Accounts. Until the date five (5) years after the Effective Time, the Seller shall retain all rights to the unleased owner joint interest billing account balances (the “Unleased A/R”) and unleased owner revenue account balances (the “Unleased Revenue”), as of the Effective Time (the Unleased A/R and the Unleased Revenue are collectively referred to herein as the “Unleased Accounts”). For a period of five (5) years following the Effective Time, the Seller shall retain the Unleased Accounts pursuant to this section, and the Seller shall be entitled to all proceeds recovered by the Buyer from unleased owners with Unleased A/R (up to the full Unleased A/R account balance for each such owner as of the Effective Time) as a result of any purchase of unleased property, mineral leasing or payment of a revised joint interest billing by any such Person (including Buyer) following a unit reduction. The Seller shall retain a copy of any decks related to the Unleased Accounts as of the Effective Time, and the Buyer agrees to provide the Seller quarterly updates regarding the Buyer’s purchase, leasing, unit reduction and revised joint interest billing activities affecting the Unleased Accounts. The Buyer further agrees to promptly deliver to the Seller all resulting proceeds on a quarterly basis. The Seller shall thereafter deliver to the Buyer corresponding Unleased Revenue that is then due to any Person (including Buyer) on account of payment by the Buyer to the Seller of such proceeds. Upon receipt of any Unleased Revenue, the Buyer shall assume all payment obligations relating to such Unleased Revenue and shall be liable for the payment thereof to the proper Persons. The Seller waives any and all rights to the Unleased A/R and Unleased Revenue from and after the five (5) year anniversary of the Effective Time, and at such time the Seller shall deliver all Unleased Revenue not previously delivered hereunder and supply all necessary data, and the Buyer shall assume all payment obligations and shall be responsible and liable for the payment thereof to the proper Persons.

The Parties agree to use reasonable efforts to reach an agreement on any and all disputed items in the draft Form 8594 within twenty (20) days after the later of the Seller’s receipt of the Buyer's draft Form 8594 or Buyer's receipt of any exceptions timely submitted by the Seller; provided, however, that if the Parties are unable to agree upon a final Form 8594, then the Parties agree to engage an Accounting Referee to resolve such dispute in accordance with the procedures set forth in Section 2.8 of this Agreement.

5.Covenants. The Parties hereby covenant and agree to perform the following:

5.1. Access to Properties and Information. Buyer will have the opportunity to conduct, prior to the Defect Notice Date and at its sole risk and expense, an environmental assessment of the Properties, including a Phase I assessment as that term is defined by the ASTM E1527-13 All Appropriate Inquiry Standard. Seller will provide reasonable access for this purpose to Properties operated by Seller. Notwithstanding anything herein to the contrary, Buyer shall not conduct any ASTM Phase II environmental review or any test drilling or sampling or other invasive activities without prior notice to and consent of Seller (which notice shall be sent at least fifteen (15) daysprior to the Defect Notice Date, and which consent Seller may give or withhold in its sole discretion, and which consent will be considered denied by Seller if Seller fails to respond within five (5) Business Days after receiving such notice). Buyer shall provide Seller with a minimum of three (3) Business Days’ advance notice of its proposed environmental assessment activities prior to entering the Property to be assessed and Buyer shall (a) coordinate the conduct of such environmental assessment with Seller’s representatives, (b) not interfere with the normal operation of the Properties, and (c) comply with all applicable Laws and all requirements and safety policies of Seller and, if Seller is not the operator of the Properties, the operator of the Properties. If Buyer or any of its consultants, agents and representatives prepares an environmental assessment, Buyer will furnish a copy thereof to Seller upon request and (until and unless Closing occurs and Buyer purchases the relevant Properties) will keep (and cause its consultants, agents and representatives to keep) any and all such assessments and reports strictly confidential. In connection with the granting of such access, Buyer represents that it is adequately insured and, except to the extent caused by the gross negligence or willful misconduct of the Seller Indemnified Parties, Buyer waives, releases and agrees to defend and indemnify the Seller Indemnified Parties against any and all claims for injury to, or death of, persons or for damage to property arising in any way from the access afforded to Buyer hereunder or the activities of Buyer related to such access or any environmental assessment. This waiver, release and indemnity by Buyer shall survive termination of this Agreement. If Buyer conducts a Phase I assessment that indicates that a Phase II assessment as that term is defined by

PURCHASE AND SALE AGREEMENT 37

the ASTM E1903 – 11 should be conducted and if Buyer timely requests the consent of Seller to such a Phase II assessment but Seller’s consent is denied (or deemed denied as provided above), then Buyer may exclude the affected Property from the Transaction Documents, in which case the Purchase Price shall be reduced by an amount equal to the Allocated Value of the affected Property and that Property shall thereafter constitute an Excluded Asset.

Insofar as related to the Properties, the Seller will give to the Buyer and its agents and representatives, reasonable access to all of the Records and the Seller will cause its officers and employees to furnish to the Buyer and its agents and representatives such operating data and other information with respect to the Properties as the Buyer may, from time to time, reasonably request; provided, however, (a) any such investigation will be conducted in such manner as not to interfere unreasonably with the operation of the business of the Seller, and (b) the Seller shall not be required to provide any of the foregoing information to the extent that the Seller is prohibited by any Third Party agreement from sharing such information with the Buyer (provided that the Seller shall use commercially reasonable efforts (at no cost to the Seller) to obtain the consent of such Third Parties to the sharing of such information). Buyer acknowledges that, pursuant to its right of access to the Records, Buyer will become privy to confidential and other information of the Seller and that such confidential information shall not be used for any purpose other than assessing the transactions contemplated by this Agreement and shall be held confidential by Buyer in accordance with the terms of the Confidentiality Agreement. If the Closing should occur, the foregoing confidentiality restriction on Buyer, including those contained in the Confidentiality Agreement to the extent related to the Records, shall terminate (except as to (a) any Properties that are excluded from the transactions contemplated hereby pursuant to the provisions of this Agreement, (b) the Excluded Assets and (c) information related to any assets other than the Properties, which confidentiality obligations shall terminate in accordance with the Confidentiality Agreement).

5.2. Conduct of Business.

5.2.1 From and after the Execution Date until Closing, the Seller will:

(a) to the extent the Seller operates any Properties, operate such Properties as a prudent operator in accordance with all Contracts and all applicable Laws in the Ordinary Course of Business;

(b) maintain its books of account and records relating to the Properties in the usual, regular and ordinary manner, in accordance with the usual accounting practices of the Seller and GAAP;

(c) pay, as they become due, that portion of the expenses related to the Properties that are attributable or allocated to the Seller’s interest in the Properties, except for amounts contested in good faith;

PURCHASE AND SALE AGREEMENT 38

(d) notify Buyer of any election that the Seller is required to make under any Contract, specifying the nature and time period associated with such election, and consult with the Buyer (and attempt in good faith to reach a mutually acceptable agreement with the Buyer regarding such election);

(e) notify Buyer, in a timely manner, of any Real Property Interest expirations or intention not to conduct any continuous drilling or other operations obligations that would result in any termination or expiration of any Real Property Interest prior to the Closing Date, and consult with the Buyer (and attempt in good faith to reach a mutually acceptable agreement with the Buyer regarding actions, if any, to be taken in connection therewith); and

(f) act in a reasonably prudent manner to maintain in full force and effect its Permits.

5.2.2 Except as provided in the Contracts, as required by Law or Permit, or as specifically contemplated by this Agreement, from and after the Execution Date until Closing, the Seller shall not:

(a) convey, encumber (except for Permitted Encumbrances), abandon or otherwise dispose of any part of the Properties, other than: (i) the sale of Hydrocarbons or obsolete machinery and equipment in the Ordinary Course of Business, unless the Buyer shall otherwise consent in writing (such consent not to be unreasonably delayed, conditioned or withheld) or (ii) the assignment of interests to another joint working interest owner to the extent such assignments do not, individually or in the aggregate, reduce the Seller’s Net Revenue Interest or increase the Seller’s Working Interest (without at least a proportionate corresponding increase in the Seller’s Net Revenue Interest) in any Well or Real Property Interest or reduce the Seller’s Net Acres with respect to any Real Property Interest from that shown for the Seller on Exhibit A;

(b) except in emergencies, enter into any material agreement, contract or commitment which, if entered into prior to the Execution Date, would be required to be listed in a Schedule attached to this Agreement, or materially amend or change the terms of, or terminate, extend, violate, breach or default under any such agreement, contract or commitment, or waive any right thereunder, in each case, without first consulting with the Buyer (and attempting in good faith to reach a mutually acceptable agreement with the Buyer regarding such agreement, contract or commitment);

PURCHASE AND SALE AGREEMENT 39

(c) enter into any transaction, the effect of which would be to reduce the Seller’s NRI in a Property from that shown on Exhibit A; provided, however, for clarity, this Section 5.2.2(c) shall not apply to any decision to become a non-consenting party in any operation proposed with respect to any of the Properties;

(d) become a non-consenting party in any operation proposed with respect to any of the Properties without first consulting with the Buyer (and attempting in good faith to reach a mutually acceptable agreement with the Buyer regarding such election);

(e) relinquish voluntarily its position as operator with respect to any Property without first consulting with the Buyer (and attempting in good faith to reach a mutually acceptable agreement with the Buyer regarding the operatorship of such Property);

(f) except for those existing as of the Execution Date, encumber any Property of the Seller with any Required Consent or PPR in favor of any Third Party; or

(g) waive, compromise or settle any material claim involving the Properties without first consulting with the Buyer (and attempting in good faith to reach a mutually acceptable agreement with the Buyer regarding such claim).

The Buyer acknowledges that the Seller owns an undivided interest in certain of the Properties with respect to which the Seller is not the operator, and Buyer agrees that the acts or omissions of the other Working Interest owners (including the operators) who are not the Seller or an Affiliate of the Seller shall not constitute a breach of the provisions of this Section 5.2, nor shall any action required by a vote of Working Interest owners constitute such a breach so long as the Seller, in either case, has voted its interest in a manner that complies with the provisions of this Section 5.2.

Without expanding any obligations which Seller may have to Buyer, it is expressly agreed that Seller shall never have any liability to Buyer with respect to any breach or failure of Section 5.2 greater than that which it might have as the operator to a non-operator under the applicable operating agreement (or, in the absence of such an agreement, under the AAPL 610 (1989 Revision) form Operating Agreement), IT BEING RECOGNIZED THAT, UNDER SUCH AGREEMENTS AND SUCH FORM, THE OPERATOR IS NOT RESPONSIBLE FOR ITS OWN NEGLIGENCE, AND HAS NO RESPONSIBILITY OTHER THAN FOR GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

5.3. Revenues Held For Benefit of the Other Party. In the event either (a) the Buyer receives production or other revenues attributable to any of the Properties for any

PURCHASE AND SALE AGREEMENT 40

periods prior to the Effective Time or (b) the Seller receives production or other revenues attributable to any of the Properties for any periods after the Effective Time, the receiving Party will hold such revenues for the exclusive benefit of the Party entitled thereto and, if not taken into account for purposes of the Final Statement, shall promptly deliver such funds to the appropriate Party.

5.4. Revenues and Expenses. For all purposes, including adjustments to the Purchase Price under Section 2 of this Agreement, the Seller and the Buyer will properly allocate revenues and expenses before and after the Effective Time and will make payments to each other to the extent necessary for such proper allocation. All expenses incurred in the operation of the Properties before the Effective Time will be borne by the Seller and all proceeds from the sale of Hydrocarbons produced from or attributable to the Properties prior to the Effective Time will be the property of the Seller, and all expenses incurred in the operation of the Properties after the Effective Time will be borne by the Buyer and all proceeds from the sale of Hydrocarbons produced from or attributable to the Properties after the Effective Time will be the property of the Buyer. Ad valorem Taxes, property Taxes and other similar obligations will be prorated between the Seller and the Buyer as of the Effective Time.

5.5. Suspended Funds. As part of the final accounting in connection with the Final Statement pursuant to Section 2.8, the Seller will deliver to the Buyer the Suspended Funds along with an “Excel” spreadsheet containing the owner name, owner number, social security or federal ID number, reason for suspense, and the amount of Suspended Funds payable for each entry, together with monthly line item production detail including gross and net volumes and deductions for all suspense entries. Upon receipt of such information, the Buyer shall administer all such accounts and assume all payment obligations relating to the Suspended Funds in accordance with all applicable Laws, and shall be liable for the payment thereof to the proper parties, except that the Seller will retain all responsibility and liability for (a) statutory penalties and interest, if any, owing to any interest owner attributable to the Suspended Funds accruing prior to the Effective Time and (b) penalties and interest, if any, attributable to the Suspended Funds accruing prior to the Effective Time, payable to any state under existing escheat or unclaimed property statutes. If any such penalties or interest are due to the respective suspense account owner or any state under such statutes and the Seller fails to promptly reimburse such sums to the Buyer, then the Buyer shall return to the Seller the Suspended Funds in such account that existed as of the Effective Time, and the Seller shall thereupon assume all obligations for the final payment and settlement of any such claims and accompanying Suspended Funds.

5.6. HSR Act. In the event the Parties determine that filings by the Parties are required under the HSR Act, within ten (10) days following the execution by the Buyer and the Seller of this Agreement, the Buyer and the Seller will each prepare and simultaneously file with the Department of Justice (“DOJ”) and Federal Trade Commission (“FTC”) the notification and report form required for the transactions contemplated by this Agreement by the HSR Act, and request early

PURCHASE AND SALE AGREEMENT 41

The Buyer and the Seller shall cooperate with each other and, subject to the terms of the Confidentiality Agreement, shall promptly furnish all information to the other Party that is necessary in connection with the Buyer’s and the Seller’s compliance with the HSR Act. The Buyer and the Seller shall keep each other fully advised with respect to any requests from or communications with the DOJ or FTC concerning such filings and shall consult with each other with respect to all responses thereto. Each of the Seller and the Buyer shall use its reasonable efforts to take all actions reasonably necessary and appropriate in connection with any HSR Act filing to consummate the transactions consummated hereby. All filing fees incurred in connection with the filings made pursuant to this Section 5.6 shall be borne by the Buyer.

5.7. Governmental Bonds. Buyer acknowledges that none of the bonds, letters of credit and guarantees, if any, posted by Seller or its Affiliates with Governmental Authorities or other Third Parties and relating to the Properties will be transferred to Buyer. Prior to Closing, Buyer shall post all bonds and other security with all applicable Governmental Authorities (in each case meeting the requirements of such authorities) as are necessary for Buyer to own and operate the Properties. In addition, at or immediately following Closing, Buyer shall replace those bonds, letters of credit and guarantees of Seller or its Affiliates related to the Properties and of which Buyer has been notified by Seller at least ten (10) Business prior to Closing. Thereafter, if either Party identifies any additional bond, letter of credit or guarantee of Seller or its Affiliates related to any Properties and which has not been released, then such Party shall promptly notify the other Party and promptly thereafter Buyer shall replace such bond, letter of credit or guarantee.

If Enterprise refuses to consent to such partial assignment of the ATEX Agreement to Buyer upon terms

PURCHASE AND SALE AGREEMENT 42

acceptable to both the Seller and the Buyer in each Party’s sole discretion, prior to Closing, the Buyer will enter into and the Seller will cause CEMI to enter into: (a) a capacity use agreement with Enterprise, wherein the Buyer, as agent for CEMI, transports the Buyer ATEX Volume under the ATEX Agreement and delivers such Buyer ATEX Volume at the delivery points under the ATEX Agreement for sale or marketing by the Buyer; and (b) an agreement detailing CEMI’s and the Buyer’s obligations to each other under the capacity use agreement, including, without limitation, the Buyer’s obligations to reimburse costs and expenses under the ATEX Agreement that are attributable to the Buyer ATEX Volume to CEMI. If Enterprise does not agree to enter into a capacity use agreement with the Buyer and CEMI, then the Buyer will enter into, and Seller will cause CEMI to enter into, a buy-sell agreement, whereby CEMI will purchase the Buyer ATEX Volume at the inlet to the ATEX pipeline and redeliver to the Buyer the Buyer ATEX Volume at any delivery point available (without additional cost and with the Buyer responsible for all ATEX Agreement charges attributable to the Buyer ATEX Volume) to CEMI per the Buyer’s instructions. CEMI will not be responsible for any incremental storage, transfer, or other handling fees the Buyer may be subject to under the buy-sell agreement. Notwithstanding anything to the contrary in this Agreement, if the Buyer is unable to take assignment of the Ethane Purchase Agreement between CEMI and Westlake Petrochemicals LLC dated January 17, 2012 (the “Westlake Agreement”), then the Buyer will sell to CEMI (or CEMI will not sell back to the Buyer if a buy-sell agreement is in effect) the volumes necessary to fulfill the Buyer’s share of the obligations retained by CEMI under the Westlake Agreement at the price in effect under the Westlake Agreement net of midstream fees and deductions.

5.8.2 Consents. Within seven (7) Business Days after the Execution Date, the Seller will send letters seeking consents to the assignment of the Contracts listed on Schedule 5.8.2 (“Midstream Consent Contracts”). The Seller and the Buyer will thereafter use commercially reasonable efforts (at no cost to the Seller) to obtain such consents. At or prior to Closing, the Buyer will use its commercially reasonable efforts to furnish to the Seller a written acknowledgement from the counterparty to each Midstream Consent Contract that (a) any required consent thereunder to assignment of such Midstream Consent Contract has been granted, (b) the Buyer meets the creditworthiness standard, if any, set forth in such Midstream Consent Contract, and (c) upon the Seller’s assignment of such Midstream Consent Contract to the Buyer, the Seller and/or CEMI, as applicable, will be released from all obligations under such Midstream Consent Contracts (with respect to each Midstream Consent Contract, the “Applicable Consent”). The Buyer agrees to supply such guaranties or other credit support necessary to replace the credit support provided by CEMI or its Affiliates or otherwise reasonably required by such counterparty to meet any such creditworthiness standard. If the Buyer is unable or otherwise

PURCHASE AND SALE AGREEMENT 43

fails to furnish to the Seller at or prior to Closing the Applicable Consent with respect to any Midstream Consent Contract, then, in any such event, such Midstream Consent Contract will not be assigned and, if the applicable Midstream Consent Contract is a gas sales contract, processing contract or similar contract for the sales of hydrocarbons, the Buyer will sell all hydrocarbons currently flowing under such Midstream Consent Contract to CEMI at the receipt points under such Midstream Consent Contract for a price equal to 100% of CEMI’s sale price of such hydrocarbons less the Applicable Deductions (as hereinafter defined), and if the applicable Midstream Consent Contract is a gathering contract, field services contract or other contract for the provision of gathering, transportation, compression or treating services for a fee or rate, CEMI will schedule, nominate and purchase all volumes delivered by Buyer in accordance with such Midstream Consent Contract at the inlet to the applicable system and redeliver to the Buyer the volume or quantity to which CEMI is entitled under the applicable Midstream Consent Contract at any delivery point available (less Applicable Deductions) to CEMI per the Buyer’s instructions, until the earlier of: (i) the termination of such Midstream Consent Contract; (ii) the expiration of the term of such Midstream Consent Contract; or (iii) the counterparties’ consent to the assignment to the Buyer and the release of the Seller and/or CEMI, as applicable, under such Midstream Consent Contract. As used herein, “Applicable Deductions” means (x) during the period from the Closing Date through the end of the second month after the month the Closing occurs, reimbursement to CEMI for all fees and deductions charged to or paid by CEMI in connection therewith (the “Initial Period”); and (y) commencing on the first day of the month following the end of the Initial Period, an amount equal to one and one-half percent (1½ %) of the sales price of such Hydrocarbons plus all midstream fees and deductions charged to or paid by CEMI in connection therewith.

5.8.3 Form of Assignment. Prior to Closing, the Seller and the Buyer will negotiate in good faith mutually acceptable forms of assignment, assumption and, as applicable, and consent and release agreements to effect, in accordance with the terms of this Agreement, the assignments to the Buyer at Closing of the Midstream Consent Contracts (subject to Section 5.8.2) and all other gathering Contracts set forth on Exhibit C (collectively, the “Midstream Agreements” and such assignment, assumption and consent agreements for the Midstream Agreements, collectively, the “Midstream Assignments”). Upon Closing, the Seller will assign (and cause CEMI to assign) its rights and obligations contained in the Midstream Agreements (subject to Section 5.8.2), and the Buyer will assume (and, upon delivery by the Seller of the Assignment, the Buyer shall be deemed to have assumed), and thereafter will be bound by and comply with and perform, all of the obligations of CEMI and the Seller contained in the assigned Midstream Agreements; in such each

PURCHASE AND SALE AGREEMENT 44

case, from and after the Effective Time and solely to extent pertaining to the Properties.

Affiliates to, cooperate with arranging for each counterparty under the FERC Jurisdictional Contracts to post the Seller’s and its Affiliates’ pre-arranged permanent capacity release to the Buyer or its designee of their interests in the FERC Jurisdictional Contracts, and if the release of such FERC Jurisdictional Contracts is not at the maximum recourse rate, the Buyer or its designee will have the right to match any higher bid pursuant to the tariffs of the interstate pipelines providing transportation service pursuant to the FERC Jurisdictional Contracts. If the rate for any FERC Jurisdictional Contract is a negotiated rate, then the Buyer and the Seller shall cooperate to seek any waivers necessary to enable the Seller or its Affiliates to release that FERC Jurisdictional Contract at a rate that results in the permanent release of the Seller or its Affiliate, without further payment obligations to the relevant pipeline. If Seller releases capacity to Buyer without FERC Waivers pursuant to this Section 5.11.3, Seller agrees to exercise any rights of first refusal or extension options under the FERC Jurisdictional Contract(s) involved at Buyer’s direction, cost and expense. After the date that is six (6) months after Closing, the Seller may take the action described above without first obtaining the Buyer’s request or consent.

5.12. Satisfaction of Conditions.

From the Execution Date until Closing, unless this Agreement is terminated, the Seller shall maintain the Records (including, as applicable, any confidentiality thereof) as would a reasonably prudent owner and operator of oil and gas properties, subject to the requirements of the Real Property Interests and any other applicable contracts. Without limiting Seller’s obligations under Section 8.4, if Closing occurs, then for a period of one (1) year after the Closing Seller shall maintain in confidence those Records to the extent related to the Properties that are conveyed to Buyer. The foregoing obligations of confidentiality shall not apply to (a) any information that is or becomes generally available to the public through no fault of Seller, or that is or was communicated to Seller by a Third Party free of any obligation of confidence known to Seller, or (b) any Records to the extent related to any Property not conveyed to Buyer or to the extent related to any Retained Liabilities. Seller may disclose any information to the extent necessary and appropriate to company with applicable Law, or to attorneys of litigants or Governmental Authorities to comply with any obligation imposed on Seller or its Affiliates in connection with a proceeding in a court or other Governmental Authority of competent jurisdiction.

5.14. Development Agreement. If the conditions set forth in Sections 6.4(a), 6.4(b), 7.5(a) and 7.5(b) are satisfied, but SUSA does not agree in writing that the Properties to be assigned to the Buyer hereunder will, effective upon such

PURCHASE AND SALE AGREEMENT 48

assignment, cease to be subject to the Development Agreement in all respects and cease to be “Joint Interests” under the Development Agreement, then promptly thereafter Seller will deliver a copy of the Development Agreement to Buyer and Buyer agrees to keep the Development Agreement strictly confidential pursuant to the terms of the Confidentiality Agreement.

If Buyer notifies Seller that Buyer is willing to assume and accept at Closing the DA Assumed Obligations, then (a) the conditions set forth in Sections 6.4(c) and 7.5(c) will be satisfied and (b) Buyer will assume and be assigned, and Seller will be fully released from, the DA Assumed Obligations pursuant to an assignment and assumption agreement to be executed and delivered by the Parties at Closing in form and substance sufficient to accomplish (and that satisfies the requirements of the Development Agreement with respect to) such assignment, assumption and release.

5.15. Selling Affiliates. To the extent any of the Properties or any of the fee minerals described on Exhibit A under the heading Fee Mineral Lease are held by any Affiliates of Seller, then, subject to the other terms of this Agreement, Seller will cause such Affiliates (a) to transfer title to such Properties by an assignment substantially in the form of the Assignment or to deliver the corresponding Fee Mineral Lease, as applicable, to Buyer, in each case, at the Closing and (b) to comply with any other terms of this Agreement to the extent specifically pertaining to such Properties or Fee Mineral Leases.

No claim of the Buyer or the Buyer Indemnified Parties pursuant to Section 10.2(a) shall be made hereunder until the total of all Individual Claims exceeds one and one-tenth percent (1.1%) of the unadjusted Purchase Price (the “Basket”). If the total amount of all of the Buyer’s or the Buyer Indemnified Parties’ Individual Claims exceeds the Basket, then the Seller’s obligations under Section 10.2(a) shall be limited to the amount by which the aggregate amount of such Individual Claims exceeds the Basket. All of the representations and warranties set forth in this Agreement or any certificate that are qualified as to “material,” “materiality,” “material respects,” “material adverse effect,” “Material Adverse Effect” or words of similar import or effect shall be deemed to have been made without any such qualification solely for purposes of determining whether a claim exceeds the Individual Claim threshold or Basket or whether the Buyer is entitled to indemnification under Section 10.2(a) for a breach by the Seller of a representation or warranty contained in Section 3.6 (and, for the avoidance of doubt, not for purposes of determining whether a Closing condition has been satisfied or whether the Buyer is entitled to indemnification under Section 10.2(a) for a breach by the Seller of any other representation or warranty contained in Section 3).

10.7.2 In no event will the Seller’s aggregate liability under Section 10.2(a), other than claims for breaches of the representations and warranties made in Sections 3.1, 3.2, 3.3(a)(i), 3.10 and 3.11, exceed twenty percent (20%) of the unadjusted Purchase Price.

10.7.3 The amount of any indemnification provided under Section 10.2 or 10.3 shall be net of any corresponding insurance proceeds, from insurance

PURCHASE AND SALE AGREEMENT 57

policies carried by the Party otherwise entitled to such indemnification or its Affiliates, in each case, that are actually realized by such Party.

10.7.4 Notwithstanding anything stated herein to the contrary: (a) neither Party will have any liability to the other Party or such other Party’s indemnified parties under this Section 10 with respect to any item for which an adjustment has already been made to the Purchase Price under the terms of this Agreement; and (b) the Seller will have no liability to the Buyer or the Buyer Indemnified Parties under this Section 10 for any matter (including any breach of a representation or warranty under Section 3) which constitutes a Title Defect or an Environmental Defect. Claims for Title Defects or Environmental Defects, whether or not resulting in a Purchase Price adjustment because the applicable Aggregate Defect Threshold is not exceeded, are not subject to the terms of this Section 10, may not be claimed under this Section 10, may not be included for purposes of determining whether the limitations set forth in this Section 10.7 have been met and may not be included in the Basket for purposes of the limitations set forth in this Section 10.7.

10.7.5 The Parties specifically agree that the Buyer will not have any right to pursue a claim under the special warranty of title in the Assignment with respect to any matters which existed on or before the Effective Time that were raised by the Buyer as a Title Defect under Section 2.1 of this Agreement.

11.Termination. The Parties agree that this Agreement is subject to termination as follows:

11.1. Right to Terminate. Subject to Section 11.2, this Agreement may be terminated (except for the provisions referenced in Section 11.2) at any time prior to the consummation of the Closing upon the occurrence of any one or more of the following: (a) by mutual consent of the Seller and the Buyer; (b) by the Buyer, if the Seller has materially breached this Agreement and such breach causes any of the conditions to Closing set forth in Section 6 not to be satisfied (or, if prior to Closing, is of such a magnitude or effect that it will not be possible for such condition to be satisfied); provided, however, that in the case of a breach that is capable of being cured, the Seller shall have a period of ten (10) days following receipt of such notice to attempt to cure the breach and the termination under this Section 11.1(b) shall not become effective unless the Seller fails to cure such breach prior to the end of such ten (10) day period; (c) by the Seller if the Buyer has materially breached this Agreement and such breach causes any of the conditions to Closing set forth in Section 7 not to be satisfied (or, if prior to Closing, is of such a magnitude or effect that it will not be possible for such condition to be satisfied); provided, however, that in the case of a breach that is capable of being cured, the Buyer shall have a period of ten (10) days following receipt of such notice to attempt to cure the breach and the termination under this Section 11.1(c) shall not become effective unless the Buyer fails to cure such breach prior to the end of such ten (10) day period; (d) by the Seller or the Buyer

PURCHASE AND SALE AGREEMENT 58

if the Closing shall not have occurred on or before March 15, 2015, provided that such failure does not result primarily from the terminating Party’s material breach of its representations, warranties or covenants contained in this Agreement; or (e) by either the Seller or the Buyer, if under the HSR Act or otherwise, the FTC or the DOJ shall have commenced or threatened to commence any proceeding to delay or enjoin or seek damages in respect of the transactions evidenced by this Agreement (“threatened,” for purposes of this Section 11.1(e), means an actual vote of the Commissioners of the Federal Trade Commission to commence such a proceeding).

11.2. Effect of Termination. In the event of termination, written notice thereof will be given to the other Party or Parties specifying the provision pursuant to which such termination is made. Except as specifically provided in Section 12, on the termination of this Agreement the Deposit will be refunded to the Buyer. If this Agreement is terminated in accordance with Section 11.1, the provisions contained in this Section 11.2 and in Sections 8.5, 9, 12, 13, 14.1, 14.2, 14.5 through 14.17, and such defined terms in Section 1 as may be required to give meaning to such sections, shall survive termination of this Agreement. No termination of this Agreement under Section 11 shall relieve any Party of liability for breach of this Agreement arising prior to such termination.

12.Default. If any Party fails to perform any material obligation contained in this Agreement that is to be performed at or prior to Closing, and Closing has not yet occurred, the Party claiming default will serve written notice to the other Party specifying the nature of such default and demanding performance. If such a material default by the Seller has not been cured within the sooner of ten (10) days after receipt of such default notice or the date specified in Section 11.1(d) above, and each of the conditions contained in Section 7 has been either fulfilled in all material respects or waived in writing (other than conditions pertaining to the execution and delivery of documents and payment of monies by the Buyer the fulfillment of which is expressly provided to occur at the Closing), then the Buyer will be entitled to exercise all remedies arising at law or in equity by reason of such default, including termination of this Agreement pursuant to Section 11. If such a material default by the Buyer has not been cured within the sooner of ten (10) days after receipt of such default notice or the date specified in Section 11.1(d) above, and each of the conditions contained in Section 6 has been either fulfilled in all material respects or waived in writing (other than conditions pertaining to the execution and delivery of documents the fulfillment of which is expressly provided to occur at the Closing), then the Seller will be entitled to retain the Deposit as liquidated damages in lieu of all other damages (and as the Seller’s sole remedy in such event, other than termination of this Agreement). The Parties hereby acknowledge that the extent of damages to the Seller occasioned by such failure or refusal by the Buyer would be impossible or extremely impractical to ascertain and that the amount of the Deposit is a fair and reasonable estimate of such damages under the circumstances.

13.    Arbitration. Except with respect to disputes and matters required to be resolved by the Consultant(s) or the Accounting Referee, which will be resolved as provided in Sections 2.1.11 or 2.8, any and all Arbitrable Disputes must be resolved through the use of binding arbitration in accordance with the Commercial Arbitration Rules of the AAA, as supplemented to

PURCHASE AND SALE AGREEMENT 59

If there is any inconsistency between this Section 13 and the Commercial Arbitration Rules or the Federal Arbitration Act, the terms of this Section 13 shall control the rights and obligations of the Parties.

13.1. Consolidation. If there is more than one (1) Arbitrable Dispute that involves the same facts and Parties as the facts and Parties with respect to which arbitration has been initiated pursuant to this Agreement, such disputes shall be consolidated into the first arbitration initiated pursuant to this Agreement.

13.2. Initiation; Selection of Arbitrators. Arbitration may be initiated by a Party (“Claimant”) serving written notice on the other Party (“Respondent”) that the Claimant has referred the Arbitrable Dispute to binding arbitration. Claimant’s notice initiating binding arbitration must describe in reasonable detail the nature of the Arbitrable Dispute and the facts and circumstances relating thereto and identify the arbitrator Claimant has appointed. Respondent shall respond to Claimant within thirty (30) days after receipt of Claimant’s notice, identifying the arbitrator Respondent has appointed. All arbitrators must be neutral parties who have never been officers, directors or employees of, or have performed material work for, any of the Parties or their Affiliates within the preceding five (5) year period. Arbitrators must have a formal education or training in the area of dispute resolution and must have not less than seven (7) years’ experience as a lawyer in the energy industry with experience in exploration and production issues. The two (2) arbitrators so chosen shall select a third arbitrator within thirty (30) days after the second arbitrator has been appointed. If either the Respondent fails to name its Party-appointed arbitrator within the time permitted, or if the two arbitrators are unable to agree on a third arbitrator within thirty (30) days from the date the second arbitrator has been appointed, then the missing arbitrator(s) shall be selected by the AAA with due regard given to the selection criteria above and input from the Parties and other arbitrators. The AAA shall select the missing arbitrator(s) not later than ninety (90) days from initiation of arbitration. In the event the AAA should fail to select the third arbitrator within ninety (90) days from initiation of arbitration, then either Party may petition the Chief United States District Judge for the Northern District of Texas to select the third arbitrator. Such selection shall be consistent with the selection criteria above and with due regard given to input from the Parties and other arbitrators.

13.3. Expenses. Claimant and Respondent shall each pay one-half of the compensation and expenses of the AAA and the arbitrator(s).

13.4. Procedure. The hearing shall be conducted in Dallas, Texas and commence within sixty (60) days after the selection of the third arbitrator, unless delayed by order of the arbitrators. The hearing shall be based upon written position papers submitted by Claimant and Respondent within twenty (20) Business Days after the selection of the third arbitrator, stating such Party’s proposed resolution of the dispute. The Parties and the arbitrators shall proceed diligently and in good faith in order that the award may be made as promptly as possible. The arbitrators

PURCHASE AND SALE AGREEMENT 60

shall determine the Arbitrable Disputes and render a final award on or before thirty (30) days following the completion of the hearing. The arbitrators’ decision shall be in writing and set forth the reasons for the award. In rendering the award the arbitrators shall abide by (a) the terms and conditions of this Agreement including, without limitation, any and all restrictions, prohibitions or limitations on damages or remedies set forth in this Agreement and (b) the law of the State of Texas. The arbitrators shall not have jurisdiction or authority to add to, detract from or alter in any way the provisions of this Agreement.

13.5. Enforcement; Remedies. A Party may, prior to the appointment of the third arbitrator, seek temporary injunctive relief from any court of competent jurisdiction, provided that the Party seeking such relief shall (if arbitration has not already been commenced) simultaneously commence arbitration. Such court-ordered relief shall not continue more than ten (10) days after the appointment of the arbitrators and in no event for longer than ninety (90) days. In order to prevent irreparable harm, the arbitrators shall have the power to grant temporary or permanent injunctive or other equitable relief. Except as provided in the Federal Arbitration Act, the decision of the arbitrators shall be binding on and non-appealable by the Parties. Each Party agrees that any arbitration award against it may be enforced in any court of competent jurisdiction and that any Party may authorize any such court to enter judgment on the arbitrators’ decisions. The arbitrators may not grant or award indirect, consequential, punitive or exemplary damages or damages for lost profits.

13.6. Award of Fees. In any action under this Agreement, the prevailing Party or Parties (or other indemnified Persons) shall be entitled to recover arbitration and court costs and attorneys’ fees in addition to any other relief to which such Party or Persons are entitled.

14.Miscellaneous. It is further agreed as follows:

PURCHASE AND SALE AGREEMENT 62

3.10, 3.11, 4.1, 4.4 and 4.8 shall survive the Closing until the expiration of the applicable statute of limitations.

14.5. No Third Party Beneficiaries.

14.6. Cumulative Remedies. Subject to the other provisions hereof, no failure on the part of any Party to this Agreement to exercise and no delay in exercising any right thereunder will operate as a waiver thereof, nor will any single or partial exercise by any Party hereto of any right hereunder preclude any other or further right of exercise thereof or the exercise of any other right.

14.7. Choice of Law. This Agreement will be interpreted, construed and enforced in accordance with the laws of the State of Texas, without giving effect to any rules or principles of conflicts of law that might otherwise refer to the laws of another jurisdiction.

14.11. Severability. If any clause or provision of this Agreement is illegal, invalid or unenforceable under any present or future law, the remainder of this Agreement will not be affected thereby. It is the intention of the Parties that if any such provision is held to be illegal, invalid or unenforceable, there will be added in lieu thereof a provision as similar in terms to such provisions as is possible to make such provision legal, valid and enforceable.

14.12. Attorney Fees. If any Party institutes an action or proceeding against any other Party relating to the provisions of this Agreement, including arbitration, the Party to such action or proceeding which does not prevail will reimburse the prevailing Party therein for the reasonable expenses of attorneys’ fees and disbursements incurred by the prevailing Party.

14.13. Waiver. Waiver of performance of any obligation or term contained in this Agreement by any Party, or waiver by one Party of the other’s default hereunder will not operate as a waiver of performance of any other obligation or term of this Agreement or a future waiver of the same obligation or a waiver of any future default.

14.14. Counterparts; Facsimiles; Electronic Transmission. This Agreement may be executed in multiple counterparts, each of which will be an original instrument, but all of which will constitute one agreement. The execution and delivery of this Agreement by any Party may be evidenced by facsimile or other electronic transmission (including scanned documents delivered by email), which shall be binding upon all Parties.

14.15. JOINT ACKNOWLEDGMENT. THIS WRITTEN AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

14.16. WAIVER OF JURY TRIAL, SPECIAL DAMAGES, ETC. EACH OF THE BUYER AND THE SELLER HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY AND IRREVOCABLY (a) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY A JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY OR ASSOCIATED HEREWITH, (b) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION OR ARBITRATION ANY “SPECIAL DAMAGES,” AS DEFINED BELOW, AND (c) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION, IN EACH CASE IT BEING THE EXPRESS INTENT, UNDERSTANDING, AND AGREEMENT OF THE PARTIES THAT SUCH WAIVERS ARE TO BE GIVEN THE FULLEST EFFECT, NOTWITHSTANDING THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY PARTY. AS USED IN THIS SECTION, “SPECIAL DAMAGES” MEANS ALL SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES (REGARDLESS OF HOW NAMED), BUT DOES NOT INCLUDE ANY PAYMENTS OR FUNDS WHICH ANY PARTY HERETO HAS EXPRESSLY PROMISED TO PAY OR DELIVER TO ANY OTHER PARTY HERETO OR ANY CLAIMS OF ANY THIRD PARTY FOR WHICH ONE PARTY HAS AGREED TO INDEMNIFY THE OTHER PARTY UNDER THIS AGREEMENT.

14.17. Mutuality. The Parties acknowledge and declare that this Agreement is the result of extensive negotiations between them. Accordingly, if there is any ambiguity in this Agreement, there shall be no presumption that this instrument was prepared solely by any Party.

14.18. Schedules. The inclusion of any information (including dollar amounts) in any section of the disclosure Schedules hereto shall not be deemed to be an admission or acknowledgment by the Seller that such information is required to be listed on such Schedule or is material to or outside the Ordinary Course of Business of the Seller.

14.19. 1031 Like-Kind Exchange. The Seller and Buyer agree that the Seller or Buyer may elect to treat the acquisition or sale of the Properties as an exchange of like-

PURCHASE AND SALE AGREEMENT 65

kind property (an “Exchange”) under section 1031 of the Internal Revenue Code of 1986, as amended (the “Code”); provided, that the Closing shall not be delayed or affected by reason of the Exchange. Each Party agrees to use reasonable efforts to cooperate with the other Parties in the completion of such an Exchange including an Exchange subject to the procedures outlined in Section 1.1031(k)-1 of the United States Treasury Regulations promulgated under the Code (the “Treasury Regulations”) and/or Internal Revenue Service Revenue Procedure 2000-37. Each of the Parties shall have the right at any time prior to Closing to assign all or a portion of its rights under this Agreement to a qualified intermediary (as that term is defined in Treasury Regulation Section 1.1031(k)-1(g)(4)(iii)) or an exchange accommodation titleholder (as that term is defined in Internal Revenue Service Revenue Procedure 2000-37) to effect an Exchange. In connection with any such Exchange, any exchange accommodation title holder shall have taken all steps necessary to own the Properties under applicable Law. Each Party acknowledges and agrees that neither an assignment of a Party’s rights under this Agreement nor any other actions taken by a Party or any other person in connection with the Exchange shall release any Party from, or modify, any of their respective liabilities and obligations (including indemnity obligations to each other) under this Agreement, and no Party makes any representations as to any particular tax treatment that may be afforded to any other Party by reason of such assignment or any other actions taken in connection with the Exchange. Any Party electing to treat the acquisition or sale of the Properties as an Exchange shall be obligated to pay all additional costs incurred hereunder as a result of the Exchange, and in consideration for the cooperation of the other Parties, the Party electing Exchange treatment shall agree to pay all costs associated with the Exchange and to indemnify and hold the other Party, its affiliates and former, current and future partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives harmless from and against any and all liabilities and taxes arising out of, based upon, attributable to or resulting from the Exchange or transactions or actions taken in connection with the Exchange that would not have been incurred by the other Parties but for the electing Party’s Exchange election.

14.20. Sharing of Certain Financial Information Subsequent to the Execution Date. After the Execution Date, the Seller shall give the Buyer (and/or any of its Affiliates) and its (and/or their, as applicable) representatives reasonable access during normal business hours to those Financial Records (as hereinafter defined), including data necessary for disclosures pursuant to ASC 805, ASC 932 or other requirements of GAAP or the Securities and Exchange Commission, necessary for the Buyer’s or its respective Affiliate’s preparation of financial statements and other financial data relating to the Properties that (a) is necessary to enable the Buyer to furnish the Financing Sources with such financial information regarding the historical performance of the Properties of the type customarily included, and required to be included, in the offering documentation reasonably requested by the Buyer and customary for public offerings of debt and equity securities or (b) may be required to be included in any current or future filing by the Buyer (and/or

PURCHASE AND SALE AGREEMENT 66

any of its Affiliates) with the Securities and Exchange Commission or other Governmental Authority (collectively, the “Financial Statements”).

14.20.1 The Financial Statements data shall be prepared and audited or reviewed at the sole cost and expense of the Buyer. If requested in writing, the Seller shall execute and deliver to the external independent accounting firm that audits, reviews or assists the Buyer or its respective Affiliate in the preparation of the Financial Statements or such other independent accounting firm designated by the Buyer to provide such procedures (the “Audit Firm”), such representation letters, in form and substance customary for representation letters provided to external audit firms by management of the company whose financial statements are the subject of an audit or are the subject of a review pursuant to Public Company Accounting Oversight Board (PCAOB) AU Section 722 (Interim Financial Information), as may be reasonably requested by the Audit Firm, with respect to the Financial Statements, including, as requested, representations regarding internal accounting controls and disclosure controls. As used in this Section 14.20, the term “Financial Records” means all ledgers, books, data, files, and accounting and financial records (whether in physical or electronic form) in the possession of the Seller and its Affiliates, in each case, solely to the extent related to the Properties; provided, however, “Financial Records” does not include any records or information (a) that the Seller considers to be confidential and proprietary, or (b) that may be protected by an attorney-client privilege, or (c) that cannot be disclosed to the Buyer or its representatives as a result of confidentiality arrangements with third parties.

14.20.2 The obligations of the Seller under this Section 14.20 shall expire on the earlier of (a) termination of this Agreement or (b) ninety (90) days after the close of the 2014 fiscal year of the Seller unless a request with respect to Financial Statements has been made prior to such time, in which event the obligations of the Seller shall continue until the preparation of such Financial Statements has been completed.

14.21. No Recourse to Financing Sources. Notwithstanding any provision of this Agreement, the Seller agrees on its behalf and on behalf of its Affiliates that no Financing Source or Finance Related Parties under any Financing Commitment nor any other Financing Source shall have any liability or obligation to the Seller and its Affiliates relating to this Agreement or any of the transactions contemplated hereby (including the Financing), whether at law, in equity, in contract, in tort or otherwise, in each case, whether arising, in whole or in part, out of comparative, contributory or sole negligence by any Financing Source or any Finance Related Party.
