(iv)    If applicable, the amount Seller is under-produced as of the Effective Time multiplied by $3.50 per MMBtu (or, with respect to oil Imbalances, $100.00 per barrel), or, to the extent that the applicable Material Contracts provide for cash balancing, the actual cash balance amount determined to be due to Seller as of the Effective Time.

(v)    Any other amount agreed upon in writing by Seller and Buyer.

(b)    Purchase Price Decreases. The Purchase Price shall be decreased by an amount equal to the sum of the following amounts, without duplication:

(i)    The amount of all proceeds of the Production received by Seller, net of all applicable Production Taxes and royalties actually paid by Seller that are attributable to the Production from the Properties for periods of time after the Effective Time, excluding all proceeds from the Production prior to the Effective Time, which shall be for Seller’s account.

Buyer shall have the right to collect any receivable, refund or other amounts associated with the Properties for periods after the Effective Time. If Seller collects any such receivable, refund or other amounts associated with periods after the Effective Time, and such amount has not been reflected as an adjustment to the Purchase Price pursuant to Section 3(a) or Section 3(b) above, then Seller shall promptly remit to Buyer such amounts.

Notwithstanding the foregoing, real property taxes and ad valorem taxes shall be prorated among Buyer and Seller on a day-for-day basis for the 2013 calendar year before and after the Effective Time. In each case, Buyer shall be responsible for the portion allocated to the period at and after the Effective Time and Seller shall be responsible for the portion allocated to the period before the Effective Time. With respect to Production Taxes attributable to the Properties for 2013, the Parties agree that: (i) such allocation and adjustment to the Purchase Price for such taxes shall be final and binding upon the Parties; and (ii) Buyer shall pay the appropriate governmental authority all such taxes applicable to the Properties for 2013, subject to Seller’s obligation to reimburse Buyer for Seller’s proportionate share of such Production Taxes as set forth in the previous sentence. Notwithstanding anything to the contrary set forth in this Agreement, for all purposes of this Agreement, Production Taxes based on or measured by production of hydrocarbons or the value thereof shall be deemed attributable to the period during which such production occurred regardless of the year when such Production Taxes are assessed or paid.

Any credit received by Buyer pertaining to such an audit claim on transactions occurring prior to the Effective Time shall be paid to Seller within thirty (30) days after receipt. In like manner, Seller shall remain solely liable for, and Buyer does not assume, any obligations due to Third Parties resulting from any operating agreement and other audit claims on transactions occurring prior to the Effective Time, and if Buyer is required to pay any such audit claim, Seller will reimburse Buyer within thirty (30) days after billing for same unless such audit claim is being contested by Seller.

Section 7.    Title and Environmental Matters.

(a)    Access. Buyer and Buyer’s authorized agents and representatives shall have the right to conduct a due diligence investigation, at Buyer’s sole risk, cost and expense, of the Properties (including the Records). Seller shall provide (or use commercially reasonable efforts to cause the operator of the Properties to provide) access to the Properties (including the Records) for Buyer to conduct a due diligence investigation and an environmental assessment of the Properties during regular business hours, which shall include weekends. Buyer agrees that Buyer and Buyer’s representatives, and their agents shall not disclose to Third Parties any information obtained in its environmental assessment unless agreed to in writing by Seller, or such disclosure is expressly required by applicable Law or Environmental Law or is compelled pursuant to legal process of any court or governmental authority; provided that, Buyer may disclose its environmental assessment

to its lenders so long as such lenders agree to maintain the confidentiality thereof. If reasonably possible and to the extent allowed by Law, Buyer shall notify Seller in advance of any such disclosure prior to the Closing Date, and shall furnish Seller copies of all materials to be disclosed prior to any disclosure thereof to Third Parties. As soon as reasonably possible after Buyer’s receipt thereof, Buyer shall deliver to Seller copies of all reports and test results from Buyer’s environmental assessment. Buyer’s failure to deliver copies of such reports or test results shall in no way constitute a waiver of any Environmental Defect asserted on or before Buyer’s Notice Date pursuant to Section 7(c).

(b)    Indemnity and Disclaimer. Buyer shall indemnify, defend, release and hold harmless Seller Indemnitees from and against any and all Claims and damages arising from or in connection with Buyer’s, and Buyer’s agents and representatives, due diligence investigation and environmental assessment of the Properties, including Claims for property damage, personal injury and death, EVEN THOUGH CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER ACTIVE, PASSIVE, SOLE, JOINT OR CONCURRENT) OR OTHER LEGAL FAULT OF THE SELLER INDEMNITEES, but excluding the gross negligence or willful misconduct of any of Seller Indemnitees. Notwithstanding anything to the contrary set forth herein, Seller shall not be required to supply any document or information or take any other action that would or may reasonably be expected to constitute a waiver of the attorney-client or other legal privilege or protection, violate any Law or Environmental Law, or result in breach of or a default under any obligation owed to a Third Party; provided that, Seller shall: (i) enter into a customary joint defense agreement or similar agreement if requested by Buyer to maintain any such privilege or protection in order to disclose any such documents or information to Buyer while preserving any such privilege or protection, and (ii) take any other action reasonably requested by Buyer to permit any such otherwise impermissible disclosure to Buyer. EXCEPT AS EXPRESSLY STATED IN THIS AGREEMENT AND IN ADDITION TO THE DISCLAIMERS SET FORTH IN SECTION 17, THE PARTIES HEREBY DISCLAIM, WAIVE AND RELEASE ANY AND ALL WARRANTIES OF ANY KIND, EXPRESS, IMPLIED, STATUTORY, AT COMMON LAW OR OTHERWISE, WITH RESPECT TO THE ACCURACY OR COMPLETENESS OF ANY INFORMATION PROVIDED BY SELLER TO BUYER. BUYER AGREES THAT ANY CONCLUSIONS DRAWN FROM INFORMATION PROVIDED BY SELLER TO BUYER SHALL BE THE RESULT OF BUYER’S OWN INDEPENDENT REVIEW AND JUDGMENT, AND AT BUYER’S SOLE RISK.

(c)    Defect Notice. Buyer shall deliver to Seller written notice of all Title Defects and Environmental Defects, including Buyer’s Knowledge that Seller owns a Working Interest or Net Revenue Interest greater than such interest as shown in Schedule 3(d) (the “Defect Notice”) not later than 5:00 p.m., Central Time on December 16, 2013 (the “Buyer’s Notice Date”). The Defect Notice shall set forth in reasonable detail: (i) the Properties affected by Title Defects and/or Environmental Defects; (ii) the nature and basis of such Title Defects and/or Environmental Defects,

including reasonable supporting documentation; (iii) the curative action it believes is necessary to cure such Title Defect or the remediation required to comply with applicable Environmental Law; and (iv) Buyer’s good faith determination of the Title Defect Value or Remediation Value. Except for any Title Defects that constitute a breach of Seller’s special warranty of title contained in the Assignment, any Title Defect that is not identified in the Defect Notice by the Buyer’s Notice Date shall thereafter be deemed a Permitted Encumbrance. Buyer shall, and does hereby accept and assume such Title Defects and Permitted Encumbrances, and Buyer hereby irrevocably disclaims, waives and releases any and all Claims against Seller arising in connection with or related to such Title Defects and the Permitted Encumbrances. Except for indemnification pursuant to Section 16(a), Buyer hereby irrevocably disclaims, waives and releases any and all Claims against Seller arising in connection with or related to Environmental Defects not set forth in the Defect Notice, regardless of when discovered or when created, and such Environmental Defects shall be, and are hereby, accepted and assumed by Buyer.

(d)    Defect Remedies. On or before 5:00 pm, Central Time on December 18, 2013 (“Seller’s Response Date”), Seller shall deliver to Buyer written notice of Seller’s response to Buyer’s Defect Notice. The Parties shall enter into good faith negotiations and shall attempt to agree on the existence of the Title Defects and Environmental Defects and the appropriate resolution thereof. If the Parties cannot reach a mutually acceptable agreement on or before the Closing, with respect to Title Defects and Environmental Defects, the following remedies shall apply:

(i)    Seller shall have the right, but not the obligation, to cure any Title Defects asserted in the Defect Notice, and to remediate any Environmental Defects asserted in the Defect Notice, at Seller’s sole cost and expense, to Buyer’s reasonable satisfaction, within ninety (90) days after the Closing.

(ii)    If a Title Defect is undisputed and liquidated in amount, then the Title Defect Value shall equal the amount necessary to be paid to remove the Title Defect from the affected Properties.

(iii)    If a Title Defect represents a discrepancy between the actual Net Revenue Interest for any Properties and the Net Revenue Interest set forth in Schedule 3(d) for such Properties, and there is a Working Interest change proportionate to the change in the Net Revenue Interest resulting from the Title Defect, then the Title Defect Value for each Property shall be the product of (A) the Allocated Value for such Property set forth on Schedule 3(d) multiplied by (B) one (1) minus a fraction, the numerator of which shall equal the actual Net Revenue Interest in such Property, and the denominator of which shall equal the Net Revenue Interest for such Property set forth in Schedule 3(d).

(iv)    If the Title Defect is of a type not described in Section 7(d)(ii) or Section 7(d)(iii), the Title Defect Value will be determined by taking into account the Allocated Value for such Properties set forth on Schedule 3(d), the portion of the Properties 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 Properties and such other factors as are necessary to make a proper evaluation of the Title Defect Value.

(v)    Buyer shall have the right to withdraw from the purchase and sale under this Agreement the Properties (collectively, the “Buyer Withdrawn Properties”) affected by Title Defects, Environmental Defects, Casualty Events and the exercise of any preferential purchase rights hereunder (collectively the “Defects”). Seller shall have the right to withdraw from the purchase and sale under this Agreement the Properties affected by the Defects hereunder (collectively, the “Seller Withdrawn Properties” and together with the Buyer Withdrawn Properties, the “Withdrawn Properties”). For the purposes of the foregoing sentences, the Properties affected by Defects shall include the entire unit or Lease that includes a Well or a Future Well affected by any Defect. At the Closing, Seller shall except and reserve the Withdrawn Properties from the Assignment, and the Purchase Price for the remaining Properties shall be reduced by the Allocated Value of the Withdrawn Properties. Notwithstanding the foregoing, until the date that is ninety (90) days from the Closing Date, the Parties shall continue to negotiate in good faith on the cost or impact of such Defect. If such defect or event cannot be cured within ninety (90) days after the Closing in accordance with Section 7(e), and the Parties cannot agree on the value or impact of such defect or event, then the subject Property shall remain a Withdrawn Property and shall be retained by Seller, and at such point each Party shall be deemed to have waived, disclaimed and released any and all Claims against the other Party arising in connection with or related to such Withdrawn Properties.

(vi)    The Parties hereby acknowledge and agree that: (A) the Properties are subject to certain deeds of trust, mortgages, security agreements and financing statements (the “Bank Liens”) granted by Seller in favor of Société Générale pursuant to that certain Amended and Restated Credit Agreement dated as of June 30, 2011, by and among Seller, the lenders named therein and Société Générale as Administrative Agent; (B) at the Closing, the Purchase Price shall be paid to such Third Party lenders and such lenders shall release the Bank Liens; and (C) at the Closing, the Properties shall be conveyed to Buyer free and clear of all liens (other than Permitted Encumbrances), deeds of trust, mortgages, security agreements and financing statements granted by, through or under Seller, including the Bank Liens.

(vii)    In addition to the waiver of any Title Defects or Environmental Defects as set forth Section 7(c) and as otherwise provided for in this Agreement, Buyer may irrevocably waive in writing any Title Defect or Environmental Defect, in which case the Purchase Price shall not be reduced and Seller shall have no further liability for the waived Title Defects or Environmental

Defects, and the Properties associated with such Title Defects or Environmental Defects shall remain properties to be transferred to Buyer at Closing.

(e)    Post-Closing Remedies. Subject to Section 7(d)(v), Seller shall have the right, but not the obligation, to cure any Title Defects or remediate any Environmental Defects affecting any of the Withdrawn Properties, at Seller’s sole cost and expense, on or before ninety (90) days after the Closing. Seller shall have the right, but not the obligation, to cause Buyer to purchase from Seller such cured and/or remediated Withdrawn Properties in accordance with the terms of this Agreement, by written notice delivered to Buyer on or before ninety (90) days after the Closing. In addition, subject to Section 7(d)(v), Buyer shall have the right, but not the obligation, to cause Seller to sell to Buyer such cured and/or remediated Withdrawn Properties in accordance with the terms of this Agreement by written notice delivered to Seller on or before ninety (90) days after the Closing. Upon receipt by Buyer of an executed and acknowledged recordable assignment (substantially in the form of Exhibit F hereto) covering such cured Withdrawn Properties, Buyer shall pay to Seller an amount equal to the Allocated Value of such cured Withdrawn Properties, less any agreed reduction.

(f)    Exclusive Remedy. Notwithstanding anything to the contrary herein, except for any Title Defects that constitute a breach of Seller’s special warranty of title contained in the Assignment, this Section 7 and the termination right contained in Section 18 shall be Buyer’s sole and exclusive remedies against Seller for Title Defects and Environmental Defects, and Buyer irrevocably waives, releases and disclaims all Claims and remedies against Seller arising in connection with or related to Title Defects and Environmental Defects.

Section 8.    Environmental Acknowledgments. Buyer hereby acknowledges and agrees as follows: (i) Buyer has entered into this Agreement on the basis of Buyer’s own investigation of the Condition of the Properties, including surface and subsurface conditions; (ii) Buyer acknowledges that the Land has been used to explore for, develop and produce oil and gas, and for the disposal of produced water, and that spills of crude oil, produced water, wastes, hazardous substances, and other materials may have occurred thereon; and physical changes to the Properties may have occurred as a result of such use; (iii) (a) low levels of NORM may be present at some locations, (b) NORM is a natural phenomenon associated with many oil fields in the U.S. and throughout the world, and (c) Buyer will make its own determination on this matter; and (iv) except as specifically provided elsewhere in this Agreement, upon Closing, Buyer shall, and does hereby, assume the risk that the Properties may contain wastes or contaminants and that adverse physical conditions, including the presence of wastes or contaminants, may not have been revealed by Buyer’s investigation.

Section 9.    Casualty Loss.

(a)    Risk of Loss. From and after the Closing Date, Buyer shall assume all risk of loss for the Properties with respect to: (i) changes in commodities prices, credit markets, and other market factors or conditions; (ii) changes in the Land; (iii) changes in production characteristics, including production declines, depletion, watering out, collapsed casing, sand infiltration or other adverse changes; and (iv) normal wear and tear.

(b)    Casualty Loss. Prior to the Closing, if a portion of the Properties is destroyed by fire or other casualty (excluding normal wear and tear, and changes in production characteristics), or if a portion of the Properties is taken or threatened to be taken in condemnation or under the right of eminent domain (collectively, a “Casualty Event”), Seller shall promptly deliver to Buyer written notice of such Casualty Event with reasonable detail of the nature of such Casualty Event, and Seller’s good faith proposal for the appropriate corrective action with respect thereto, including any environmental remediation required pursuant to applicable Environmental Law. For purposes of this Section, the “Casualty Loss” shall be equal to the lesser of either the cost of such appropriate corrective action or the Allocated Value of the Properties affected by such Casualty Event; provided, however, that, notwithstanding anything to the contrary herein, any individual Casualty Loss which is less than Fifteen Thousand Dollars ($15,000.00) individually or Sixty-Five Thousand Dollars ($65,000.00) in the aggregate (the “Casualty Threshold”) shall not be deemed a Casualty Event hereunder. Buyer hereby disclaims, waives and releases any and all Claims against Seller arising in connection with or related to any individual Casualty Loss which is less than the Casualty Threshold, and such Casualty Loss shall be accepted and assumed by Buyer.

(c)    Casualty Remedies. Seller shall have the right, but not the obligation, to elect to remedy any Casualty Loss prior to the Closing. If Seller remedies such Casualty Loss prior to the Closing to the reasonable satisfaction of Buyer, there shall be no adjustment to the Purchase Price. Seller shall not voluntarily compromise, settle or adjust any amounts payable by reason of any Casualty Event without the prior written consent of Buyer, which consent shall not be unreasonably withheld. If the Closing occurs with respect to any of the Properties affected by a Casualty Event, Seller shall assign to Buyer the proceeds of any insurance coverage or condemnation award attributable to such affected Properties in excess of Seller’s cost to remedy the Casualty Event. Notwithstanding anything to the contrary herein, Buyer shall have the right, but not the obligation, to elect to withdraw from the purchase and sale hereunder any of the Properties affected by such Casualty Event by written notice delivered to Seller on or before the Closing. Upon receipt of such notice, at the Closing, Seller shall except and reserve such affected Properties from the Assignment and such Properties shall be deemed to be Withdrawn Properties thereafter, and the Purchase Price for the remaining Properties shall be reduced by the Allocated Value of such Withdrawn Properties and Seller shall be entitled to and shall retain all insurance proceeds allocable to such Withdrawn Properties. Each Party hereby waives, disclaims and releases any and all Claims against the other Party arising in connection with or related to such Withdrawn Properties.

Section 10.    Preferential Rights and Consents. Seller shall give all required notices with respect to all Third Party preferential purchase rights and consents to assignment within five (5) Business Days of the Execution Date. The Parties shall use their commercially reasonable efforts in good faith to obtain waivers of preferential rights and consents to assignment; provided that, Buyer shall not be obligated to make any payments in connection therewith. If (i) the time period for the exercise of any preferential purchase right or consent to assignment expires prior to Closing, (ii) a preferential purchase right is waived by the holder thereof, or (iii) a consent to assignment is obtained from the applicable Third Party, then Seller shall convey the Properties affected thereby to Buyer at the Closing. In the event that any such preferential purchase right is timely exercised prior to the Closing (or, subject to the following sentence, after Closing), the applicable Properties shall cease to be a part of this transaction, and the Purchase Price shall be reduced by the Allocated Value of the applicable Properties. If the time period for any such preferential purchase right has not expired at or prior to the Closing, then the Properties affected thereby shall constitute Withdrawn Properties until such time as the time period for the exercise of such preferential purchase right expires or such preferential purchase right is waived, upon which Seller shall promptly assign such Properties to Buyer, and Buyer shall pay Seller the Allocated Value of the applicable Properties. For all Properties affected by consents to assignment that would impair any of the rights to be transferred to Buyer if not obtained, such Properties shall constitute Withdrawn Properties if such consents to assignment are not obtained prior to Closing (unless waived by Buyer), and the Purchase Price shall be reduced by the Allocated Value of the applicable Properties. If such consents to assignment are obtained after Closing, then Seller shall promptly assign such Properties to Buyer, and Buyer shall pay Seller the Allocated Value of the applicable Properties. Seller shall continue to use its reasonable efforts to obtain such consents to assignment following Closing for a period of one (1) year. Seller shall, if requested by Buyer, enter into a back-to-back contractual arrangement whereby Buyer receives all of the economic benefits of and is responsible for all of the liabilities and burdens under any Leases and Applicable Contracts and indemnifies, defends, releases and holds harmless Seller Indemnitees from and against any and all Claims and Damages arising from or in connection with any such Leases and Applicable Contracts for which consent to assignment is not obtained prior to Closing; provided that, Seller shall not obligated to perform any such back-to-back obligations for more than one (1) year after the Closing Date. If any such consents to assignment are obtained during the one (1) year period following Closing, then Seller shall promptly assign such Properties to Buyer, and Buyer shall pay Seller the Allocated Value of the applicable Properties.

Section 11.    Conditions Precedent to the Closing. The obligations of the Parties to close the transactions contemplated hereby are subject to the fulfillment before or at Closing, of each of the following conditions:

Buyer and Seller shall use their reasonable efforts in good faith to confer and resolve any objections within fifteen (15) days after Seller’s receipt of Buyer’s notice of objections.
