(m)all documents and instruments of Seller that may be protected by an attorney-client privilege, other than title opinions;

Section 1.4    Effective Time; Proration of Costs and Revenues.

(a)Subject to Section 1.5, possession of the Assets shall be transferred from Seller to Purchaser at the Closing, but for purposes of the adjustments made to the Closing Statements certain financial benefits and burdens of the Assets shall be transferred effective as of 7:00 A.M., local time, on April 1, 2012 (the “Effective Time”), as described below.

(b)“Earned” and “incurred,” as used in this Agreement, shall be interpreted in accordance

with generally accepted accounting principles and Council of Petroleum Accountants Society (COPAS) standards, as applicable. “Property Costs” means all costs attributable to the ownership and operation of the Assets (including without limitation costs of insurance relating specifically to the Assets, royalties and overriding royalties payable on account of production from the Assets, and Severance Taxes and Property Taxes, but excluding any other Taxes) and capital expenditures incurred in the ownership and operation of the Assets in the ordinary course of business and, where applicable, in accordance with the relevant operating or unit agreement, if any, and overhead costs charged to the Assets under the relevant operating agreement or unit agreement, if any, by unaffiliated third parties and, with respect to Assets operated by Seller, Four Hundred Thousand Dollars ($400,000) per month (prorated for any partial months as applicable), but excluding without limitation liabilities, losses, costs, and expenses attributable to (i) claims for personal injury or death, property damage or violation of any Law, (ii) obligations to plug wells or dismantle, abandon and salvage facilities, (iii) obligations to remediate any contamination of groundwater, surface water, soil, Equipment or Pipelines under applicable Environmental Laws, (iv) obligations to furnish make-up gas according to the terms of applicable gas sales, gathering or transportation contracts, (v) gas balancing obligations and (vi) obligations to pay working interests, royalties, overriding royalties or other interests held in suspense, all of which are addressed in Article 11 or elsewhere in this Agreement. Determination of whether Property Costs are attributable to the period before or after the Effective Time for purposes of the adjustments in the Closing Statements shall be based on when services are rendered, when the goods are delivered, or when the work is performed. For clarification, the date an item or work is ordered is not the date of a transaction for settlement purposes in the Closing Statements, but rather the date on which the item ordered is delivered to the job site, or the date on which the work ordered is performed, shall be the relevant date. For purposes of allocating Hydrocarbon production (and accounts receivable with respect thereto), (i) liquid Hydrocarbons, including natural gas liquids, shall be deemed to be “from or attributable to” the Leases, Units and Wells when they pass through the pipeline connecting into the storage facilities into which they are run or into tanks connected to the Wells and (ii) gaseous Hydrocarbons shall be deemed to be “from or attributable to” the Leases, Units and Wells when they pass through the royalty measurement meters, delivery point sales meters or custody transfer meters (whichever meter is closest to the Well) on the pipelines through which they are transported. Seller shall utilize reasonable interpolative procedures, consistent with industry practices, to arrive at an allocation of Hydrocarbon production when exact meter readings or gauging and strapping data is not available. Seller shall provide to Purchaser, no later than three (3) Business Days prior to Closing, all data necessary to support any estimated allocation, for purposes of establishing the adjustment to the Purchase Price pursuant to Section 2.2 hereof that will be used to determine the Closing Payment for purposes of the Preliminary Closing Statement (as defined in Section 9.4(a)). Taxes, right-of-way fees, insurance premiums and the Property Costs that are paid periodically shall be prorated based on the number of days in the applicable period falling before and the number of days in the applicable period falling at or after the Effective Time. Taxes that are Property Taxes shall be attributable to the periods before or after the Effective Time in accordance with Section 7.9.

 

Section 1.5    Delivery of Records.

Seller, at Purchaser's sole cost and expense, shall deliver production revenue pay decks, and Records pertaining to Lease rentals, shut-in payments and similar Lease maintenance payments, surface use rentals, joint interest billings and similar records reasonably necessary to Purchaser's

immediate operation of the Assets to Purchaser within three (3) days of Closing and shall use commercially reasonable efforts to deliver all remaining Records promptly thereafter but in no event later than thirty (30) days following Closing. Other than any original Records retained by Seller pursuant to Section 1.2(j), Purchaser shall be entitled to all original Records maintained by Seller. Seller shall be entitled to keep a copy or copies of all Records; provided, however, that Seller shall not sell or otherwise allow third parties to review, copy or otherwise use (for any purpose) any Records retained by Seller for their own account.

Section 2.1    Purchase Price.

The purchase price for the Assets (the “Purchase Price”) shall be Three Hundred Thirty Million Five Hundred Ninety-Eight Thousand Eight Hundred Dollars ($330,598,800.00) payable in United States currency by wire transfer in same day funds as and when provided in this Agreement and as adjusted as provided in Section 2.2.

Section 2.2    Adjustments to Purchase Price.

For purposes of the Closing Statements, the Purchase Price for the Assets shall be adjusted as follows (with such adjustments being made so as not to give any duplicative effect) with all such amounts being determined in accordance with generally accepted accounting principles and Council of Petroleum Accountants Society (COPAS) standards:

(a)Upward Adjustments. The Purchase Price shall be adjusted upward by the following:

the ownership and operation of the Assets that belong to Seller as of the Effective Time (which value shall be computed at the applicable third-party contract prices for the month of May 2012 for such stored Hydrocarbons);

(b)Downward Adjustments. The Purchase Price shall be adjusted downward by the following:

accordance with Section 4.3(c), subject to the Environmental Defect Deductible, the Environmental Defect Amount with respect to such Material Environmental Defect for which the Environmental Defect Amount has been determined;

Each adjustment made pursuant to Section 2.2(b)(i) shall serve to satisfy, up to the amount of the adjustment, Purchaser's entitlement to Hydrocarbon production from or attributable to the Properties during the Adjustment Period, and to the value of other income, proceeds, receipts and credits earned with respect to the Assets during the Adjustment Period, and as such, Purchaser shall not have any separate rights to receive any Hydrocarbon production or income, proceeds, receipts and credits with respect to which an adjustment has been made. Similarly, the adjustment described in Section 2.2(a)(ii) shall serve to satisfy, up to the amount of the adjustment, Purchaser's obligation to pay Property Costs and other costs attributable to the ownership and operation of the Assets which are incurred during the Adjustment Period, and as such, notwithstanding anything in this Agreement to the contrary, Purchaser shall not be separately obligated to pay for any Property Costs or other such costs with respect to which an adjustment has been made.

Section 2.3    Deposit.

Concurrently with the execution of this Agreement, Purchaser has paid to Seller an earnest money deposit in an amount equal to Twenty Million Dollars ($20,000,000.00) (the “Deposit”); provided that credit shall be given for any deposit paid by Purchaser to Seller pursuant to the letter of intent between Purchaser and Seller dated March 28, 2012. The Deposit shall be non-interest bearing (except to the extent it is returned to Purchaser in accordance with Section 10.3(b)) and applied against the Purchase Price if the Closing occurs or shall be otherwise distributed in accordance with the terms of this Agreement.

Section 3.1    Seller's Title.

(a)Except for the special warranty of title referenced in Section 3.1(b) and without limiting Purchaser's right to adjust the Purchase Price by operation of this Article 3, Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to Seller's title to any of the Assets, and Purchaser hereby acknowledges and agrees that the sole remedy for any defect of title, including any Title Defect, with respect to any of the Assets (i) before Closing, shall be as set forth in Section 3.5(d) or terminate this Agreement pursuant to Section 10.1 and (ii) after Closing, shall be Purchaser's right to adjust the Purchase Price as set forth in Section 3.5(g) or pursuant to the special warranty of title referenced in Section 3.1(b).

(b)The conveyance covering the Assets to be delivered by Seller to Purchaser shall be substantially in the form of Exhibit B (the “Conveyance”). The Conveyance shall contain a special warranty of title by, through and under Seller and its Affiliates, but not otherwise, to the Units, Leases and Wells shown on Exhibit A and Exhibit A-1 and other Assets, subject to the Permitted Encumbrances, but shall otherwise be without warranty of title of any kind, express, implied or statutory or otherwise. Any Claim by Purchaser under Seller's special warranty of title in the Conveyance shall be limited to the Allocated Value of any Units, Wells or other Assets set forth on Exhibit A-1.

(c)Purchaser shall not be entitled to protection under Seller's special warranty of title in the Conveyance against any Title Defect (i) asserted by Purchaser under Section 3.5(a) or Section 3.5(f) or (ii) actually known by Purchaser or any of its Affiliates prior to the Post-Closing Title Claim Date or (iii) any Permitted Encumbrances.

 

(d)Notwithstanding anything herein provided to the contrary, if a Title Defect under this Article 3 results from any matter which could also result in the breach of any representation or warranty of Seller set forth in Article 5, then Purchaser shall only be entitled to assert such matter as a Title Defect before Closing pursuant to Section 3.5(a), or after Closing pursuant to Section 3.5(f), and shall be precluded from also asserting such matter as the basis of the breach of any such representation or warranty.

Section 3.2    Definition of Defensible Title.

As used in this Agreement, the term “Defensible Title” means the title of Seller with respect to the Units, Wells or other Assets shown on Exhibit A-1 that, except for and subject to Permitted Encumbrances:

(a)Entitles Seller (and Purchaser from and after the Effective Time) to receive a share of the Hydrocarbons produced, saved and marketed from any Unit, Well or other Asset shown in Exhibit A-1 throughout the duration of the productive life of such Unit, Well or other Asset (after satisfaction of all royalties, overriding royalties, net profits interests or other similar burdens on or measured by production of Hydrocarbons) (a “Net Revenue Interest”), of not less than the Net Revenue Interest shown in Exhibit A-1 for such Unit, Well or other Asset, except (solely to the extent that such actions do not cause a breach of Seller's covenants under Section 7.6) for decreases in connection with those operations in which Seller may from and after the Effective Time become a non-consenting co-owner,

decreases resulting from the establishment or amendment from and after the Effective Time of pools or units (including, without limitation, force pooled units and spacing units), decreases in connection with any payouts of non-consent penalties as reflected in Exhibit A-1, and decreases required to allow other Working Interest owners to make up past underproduction or pipelines to make up past under deliveries, provided that such underproduction and under deliveries are identified on Schedule 5.14, and except as stated in such Exhibit A-1;

(b)Obligates Seller (and Purchaser from and after the Effective Time) to bear a percentage of the costs and expenses for the maintenance, development and operation of any Unit, Well or other Asset shown in Exhibit A-1 (“Working Interest”) not greater than the Working Interest shown in Exhibit A‑1 for such Unit, Well or other Asset without increase throughout the productive life of such Unit, Well or other Asset, except as stated in Exhibit A-1 and except for increases resulting from contribution requirements with respect to non-consenting co-owners under applicable operating agreements and increases that are accompanied by at least a proportionate increase in Seller's Net Revenue Interest;

(c)Is not subject to penalty or other reduction in interest attributable to a Well or Unit shown in Exhibit A-1 under any agreement with third parties or pursuant to any applicable Law in connection with any third-party operations proposal made between September 1, 2011 and the execution of this Agreement with respect to which Purchaser did not consent or otherwise failed to participate (each, a “Non-Consent Operation”), unless Purchaser is provided written notice of such Non-Consent Operation and Purchaser instructs Seller in writing not to consent or otherwise participate in such Non-Consent Operation; and

(d)Is free and clear of liens, encumbrances, obligations, security interests, irregularities, pledges, or other defects (other than Permitted Encumbrances).

Section 3.3    Definition of Title Defect.

As used in this Agreement, the term “Title Defect” means any lien, charge, encumbrance, obligation (including contract obligation), defect, or other matter (including without limitation a discrepancy in Net Revenue Interest or Working Interest) that causes Seller not to have Defensible Title in and to the Units, Wells or other Assets shown on Exhibit A-1 as of the Effective Time and the Closing. As used in this Agreement, the term “Title Benefit” shall mean any right, circumstance or condition that operates to increase the Net Revenue Interest of Seller in any Unit, Well or other Asset shown on Exhibit A-1, without causing a greater than proportionate increase in Seller's Working Interest above that shown in Exhibit A-1 as of the Effective Time. Notwithstanding the foregoing, the following shall not be considered Title Defects:

(a)defects based solely on lack of information in Seller's files;

(b)defects arising out of lack of corporate or other entity authorization unless Purchaser provides evidence that the action was not authorized and results in another Person's superior claim of title to the relevant Asset;

Body, or any assignments of such Leases, in the real property, conveyance or other records of the county in which such Property is located;

(d)defects based on a gap in Seller's chain of title in the county records as to Leases, unless such gap is affirmatively shown to exist in such records by an abstract of title, title opinion or landman's title chain (which documents shall be included in a Title Defect Notice);

(e)defects that have been cured by applicable Laws of limitation or prescription; and

(f)defects arising out of a lack of survey, unless a survey is expressly required by applicable Laws.

Section 3.4    Definition of Permitted Encumbrances.

As used herein, the term “Permitted Encumbrances” means any or all of the following:

(a)Royalties and any overriding royalties, reversionary interests and other burdens on production, to the extent that any such burden does not reduce Seller's Net Revenue Interest below that shown in Exhibit A-1 or increase Seller's Working Interest above that shown in Exhibit A-1 without a proportionate increase in the Net Revenue Interest;

(b)All Leases, unit agreements, pooling agreements, operating agreements, Hydrocarbon production sales contracts, division orders and other contracts, agreements and instruments applicable to the Assets, to the extent that they do not, individually or in the aggregate, reduce Seller's Net Revenue Interest below that shown in Exhibit A-1 or increase Seller's Working Interest above that shown in Exhibit A-1 without a proportionate increase in the Net Revenue Interest;

(c)Preference Rights set forth on Schedule 7.7 to the extent addressed by the procedures set forth in Section 7.7;

(d)Transfer Requirements set forth on Schedule 7.7 to the extent addressed by the procedures set forth in Section 7.7;

(j)Calls on Hydrocarbon production under existing Contracts that are listed on Schedule 1.2(d);

(l)Any encumbrance on or affecting the Assets which is discharged by Seller at or prior to Closing;

Section 3.5    Title Defects and Title Benefits.

(a)To assert a claim of a Title Defect prior to Closing, Purchaser must deliver a claim notices to Seller (each a “Title Defect Notice”) on or before 5:00 p.m. Central Time on June 15, 2012 (the “Title Claim Date”); provided, however, that Purchaser agrees that it will use reasonable efforts to furnish Seller once every two (2) weeks, commencing on the fourteenth (14^th) day following the date of this Agreement until the Title Claim Date, written notice of any Title Defect that any officer of Purchaser or its Affiliates discovers or learns during such two (2) week period, which may be preliminary in nature and supplemented prior to the Title Claim Date; provided, however, that the failure of Purchaser to give Seller any such preliminary notices shall not waive any Title Defects or constitute a breach of this Agreement. The Title Defect Notice shall be in writing and shall include (i) a description of the alleged Title Defect(s), (ii) the individual Units, Wells or other Assets in Exhibit A-1 affected by the Title Defect (each a “Title Defect Property”), (iii) the Allocated Value of each Title Defect Property, (iv) supporting documents reasonably necessary for Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of the alleged Title Defect(s), and (v) the amount by which Purchaser reasonably believes the Allocated Value of each Title Defect Property is reduced by the alleged Title Defect(s) and the computations and information upon which Purchaser's belief is based. For purposes hereof, the “Allocated Value” of an Asset shall mean the portion of the Purchase Price that has been allocated to a particular Unit, Well or other Asset in Exhibit A-1.

(b)Seller shall have the right, but not the obligation, to deliver to Purchaser on or before the Title Claim Date, with respect to each Title Benefit, a notice (a “Title Benefit Notice”) including (i) a description of the Title Benefit, (ii) the Units, Wells or other Assets shown on Exhibit A-1 affected, (iii) the Allocated Values of the Units, Wells or other Assets shown on Exhibit A-1 subject to such Title Benefit and (iv) the amount by which Seller reasonably believes the Allocated Value of those Units, Wells or other Assets is increased by the Title Benefit, and the computations and information upon which Seller's belief is based. Seller shall be deemed to have waived all Title Benefits of which it has not given notice to Purchaser on or before the Title Claim Date.

(c)Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure or remove a Title Defect to the reasonable satisfaction of Purchaser at any time prior to Closing (the “Cure Period”), unless the parties otherwise agree, any Title Defects of which it has been advised in writing by Purchaser.

(d)In the event that any Title Defect asserted pursuant to Section 3.5(a) is not waived by Purchaser or cured on or before Closing to the reasonable satisfaction of Purchaser, subject to the parties' rights under Section 3.5(k), at Closing, Seller, at its sole option, may:

 

(e)With respect to each Unit, Well or other Asset in Exhibit A-1 affected by Title Benefit asserted under Section 3.5(b), subject to the Individual Benefit Threshold and the Title Benefit Deductible, the Purchase Price shall be increased by an amount equal to the Aggregate Title Benefit Amounts for such property, as determined pursuant to Section 3.5(j).

(f)Purchaser shall have the right, but not the obligation to deliver a Title Defect Notice to Seller on or before 5:00 p.m. Central Time on the thirtieth (30^th) day after the Closing Date (the “Post-Closing Title Claim Date”) asserting any Title Defect, other than the Title Defects previously asserted pursuant to Section 3.5(a). Any Title Defect Notice delivered pursuant to this Section 3.5(f) shall include all of the information set forth as items (i) through (v) in Section 3.5(a). Notwithstanding any other provision of this Agreement to the contrary, but subject to Purchaser's rights in connection with the special warranty of title referenced in Section 3.1(b), Purchaser shall

be deemed to have waived its right to assert Title Defects of which Seller has not been given notice in a Title Defect Notice delivered to Seller on or before the Title Claim Date or the Post-Closing Title Claim Date.

  

(g)Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure or remove a Title Defect asserted pursuant to Section 3.5(f) to the reasonable satisfaction of Purchaser at any time within 180 days after Seller's receipt of the post-Closing Title Defect Notice. If any Title Defect asserted pursuant to Section 3.5(f) is not cured prior to such date pursuant to this Section 3.5(g) or waived by Purchaser, then subject to the parties' rights under Section 3.5(k) and (l) and such other terms and conditions herein), within ten (10) days of such date, Seller shall pay to Purchaser the Title Defect Amount for such Title Defect.

 

(h)Section 3.5(d) shall be the exclusive right and remedy of Purchaser with respect to Title Defects asserted by Purchaser pursuant to Section 3.5(a), and Section 3.5(g) shall be the exclusive right and remedy of Purchaser with respect to Title Defects asserted by Purchaser pursuant to Section 3.5(f). Section 3.5(e) shall be the exclusive right and remedy of Seller with respect to Title Benefits asserted by Seller pursuant to Section 3.5(b).

(i)For purposes of this Agreement, the “Title Defect Amount” resulting from a Title Defect shall be the amount by which the Allocated Value of the Title Defect Property is reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following methodology, terms and conditions:

to make a proper evaluation, including, that if such Title Defect is reasonably capable of being cured, the reasonable cost and expense of curing such Title Defect;

(j)Title Benefit Amount. For purposes of this Agreement, the “Title Benefit Amount” resulting from a Title Benefit shall be determined in accordance with the following methodology, terms and conditions:

reasonable factors as are necessary to make a proper evaluation.

(k)Seller and Purchaser shall attempt in good faith to agree on (i) the existence and scope of a Title Defect or Title Benefit, (ii) the Title Defect Amount or Title Benefit Amount, as the case may be, relating to the portion of the Assets affected by a Title Defect or Title Benefit and (iii) the adequacy of Seller's Title Defect curative materials and Purchaser's reasonable satisfaction thereof (collectively “Title Disputed Matters”). If, with respect to any Title Defect asserted pursuant to Section 3.5(a), Seller and Purchaser are unable to resolve one or more Title Disputed Matters on or before Closing, the affected Title Defect Property(ies) shall be conveyed to Purchaser at Closing and Purchaser shall pay an amount equal to the aggregate of all unresolved Title Defect Amounts with respect to such Title Disputed Matters into an escrow account; provided, however, such escrowed amount shall not exceed an amount equal to the sum of the Allocated Value(s) relating to the portion of the Title Defect Property(ies) subject to the Title Disputed Matters. All Title Disputed Matters, whether asserted pursuant to Section 3.5(a) or Section 3.5(f), that are unresolved by the parties shall be exclusively and finally resolved by arbitration pursuant to this Section 3.5(k). There shall be a single arbitrator, who shall be (i) a title attorney with at least ten (10) years experience in oil and gas titles involving properties in the regional area in which the Properties are located (“Title Arbitrator”), as selected by mutual agreement of Purchaser and Seller within fifteen (15) Business Days after the end of the Cure Period, and absent such mutual agreement, by the Houston, Texas office of the AAA. The arbitration proceeding shall be held in Dallas, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section 3.5(k). The Title Arbitrator's determination shall be made within fifteen (15) Business Days after submission of the matters in dispute and shall be final and binding upon both parties, without right of appeal. In making his or her determination, the Title Arbitrator shall be bound by the rules set forth in Section 3.5(i) and Section 3.5(j) and may consider such other matters as in the opinion of the Title Arbitrator are necessary or helpful to make a proper determination. Additionally, the Title Arbitrator may consult with and engage disinterested third parties to advise the expert or arbitrator, including without limitation petroleum engineers. The Title Arbitrator shall act as an expert for the limited purpose of determining the Title Disputed Matters submitted by either party and may not award damages, interest or penalties to either party with respect to any matter. Each party may submit only one Title Defect Amount with respect to each alleged Title Defect and one Title Benefit Amount with respect to each Title Benefit (provided that the foregoing shall not be construed to preclude a party from also arguing against, and the Title Arbitrator determining, the existence of a Title Defect or a Title Benefit). Seller and Purchaser shall each bear its own legal fees and other costs of presenting its case. Each party shall bear one-half of the costs and expenses of the Title Arbitrator, including any costs incurred by the Title Arbitrator that are attributable to such third party consultation. Within ten (10) days after the Title Arbitrator delivers written notice to Purchaser and Seller of his award with respect to a Title Disputed Matter pertaining to a Title Benefit or a Title Defect asserted pursuant to Section 3.5(a), the parties shall issue joint written instructions to the escrow agent to release to Seller or Purchaser, as applicable, the amount, if any, awarded by the Title Arbitrator to such party, plus the interest at the Agreed Interest Rate accrued on such amount. Within ten (10) days after the Title Arbitrator delivers written notice to Purchaser and Seller of his award with respect to a Title Disputed Matter pertaining to a Title Defect

asserted pursuant to Section 3.5(f), Seller shall pay to Purchaser the amount, if any, awarded by the Title Arbitrator to Purchaser, plus the interest at the Agreed Interest Rate accrued on such amount since the Closing Date.

  

(l)Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any individual uncured Title Defect for which the Title Defect Amount therefor does not exceed $100,000 (“Individual Title Threshold”); and (ii) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for uncured Title Defects unless the aggregate Title Defect Amounts attributable to all Material Title Defects exceeds a deductible in an amount equal to Six Million Dollars ($6,000,000) (the “Title Defect Deductible”), after which point adjustments to the Purchase Price or other remedies shall be made or available to Purchaser only to the extent the aggregate Title Defect Amounts with respect to Material Title Defects are in excess of such Title Defect Deductible. Notwithstanding the foregoing, (I) any Material Title Defect relating to a Non-Consent Operation (other than any Non-Consent Operations disclosed in Schedule 3.4(t) shall not be subject to the Title Defect Deductible, and (II) after the Title Claim Date but prior to the Post Closing Title Claim Date Purchaser shall not be entitled to claim any Title Defects in excess of the lesser of (i) $33,059,880, and (ii) the difference between forty percent (40%) of the unadjusted Purchase Price and the amount of all claims for Title Defects, Environmental Defects, Preference Rights and Casualty Losses prior to the Title Claim Date.

(c)In any event:  (i) except with respect to curative efforts that Purchaser has been deemed to have approved, each Party retains the right to dispute whether or not a Title Defect relating to the Retained Litigation has been cured, including whether or not the relevant issue constitutes a Title Defect, and (ii) any such dispute shall be resolved in accordance with the dispute resolution procedures set forth in Section 3.5(k).

(f)During all periods that Purchaser, and/or any of Purchaser's Representatives are on the Assets, Purchaser shall maintain, at its sole expense and with insurers reasonably satisfactory to Seller, policies of insurance of the types and in the amounts consistent with industry standards.

Upon request by Seller, Purchaser shall provide evidence of such insurance to Seller prior to entering upon the Assets.

(g)Unless otherwise required to be disclosed under applicable Law, all information obtained by Purchaser and its representatives pursuant to this Section 4.1 shall be subject to the terms of that certain confidentiality agreement dated August 15, 2011, by and between Merit Energy Company, LLC and Purchaser (the “Confidentiality Agreement”).

(an “Environmental Defect Notice”); provided, however, that Purchaser agrees that it will use reasonable efforts to furnish Seller once every two (2) weeks, commencing on the fourteenth (14^th) day following the date of this Agreement until the Environmental Claim Date, written notice of any Environmental Defect that any officer of Purchaser or its Affiliates discovers or learns during such two (2) week period, which may be preliminary in nature and supplemented prior to the Environmental Claim Date; provided, however, that the failure of Purchaser to give Seller any preliminary notices shall not waive any Environmental Defects or constitute a breach of this Agreement. To be effective, the Environmental Defect Notice shall set forth (i) a description of the matter constituting the alleged Environmental Defect, (ii) the Units/Wells and the associated Asset affected by the Environmental Defect (each an “Environmental Defect Property”), (iii) the estimated Lowest Cost Response to eliminate the Environmental Defect in question (the “Environmental Defect Amount”), and (iv) supporting documents reasonably necessary for Seller to ascertain the existence of the alleged Environmental Defect and the Environmental Defect Amount. For all purposes of this Agreement, Purchaser shall be deemed to have waived any Environmental Defect which Purchaser fails to assert as an Environmental Defect by an Environmental Defect Notice received by Seller on or before the Environmental Claim Date.

(b)Seller shall have the right, but not the obligation, to cure any Environmental Defect before Closing or, provided that the parties shall have agreed in writing to the general plan of remediation with respect to such Environmental Defect and the time period by which such remediation shall take place, after Closing. Purchaser shall have the right to participate in the implementation of the remediation plan, including the right to (i) observe all remediation work, and, (ii) at Purchaser's sole cost and expense, obtain split samples of any environmental media obtained during the performance of remediation work. If Seller disagrees with any of Purchaser's assertions with respect to the existence of an Environmental Defect or the Environmental Defect Amount, Purchaser and Seller will attempt to resolve the dispute prior to Closing. If the dispute cannot be resolved prior to Closing, either party may submit the dispute to an environmental consultant or professional approved in writing by Seller and Purchaser that is experienced in environmental corrective action at oil and gas properties in the relevant jurisdiction and that shall not have performed professional services for either party or any of their respective Affiliates during the previous five years (the “Independent Expert”). The Independent Expert shall conduct the dispute resolution proceeding by written submissions from Purchaser and Seller with exhibits, including interrogatories, supplemented with appearances by Purchaser and Seller, if necessary, as the Independent Expert may deem necessary. After the parties and Independent Expert have had the opportunity to review all such submissions, the Independent Expert shall call for a final, written offer of resolution from each party. The Independent Expert shall render its decision within twenty (20) Business Days of receiving such offers by selecting one or the other of the offers. The Independent Expert may not award damages, interest or penalties to either party with respect to any matter. The decision of the Independent Expert shall be final and binding upon both parties, without right of appeal. Seller and Purchaser shall each bear its own legal fees and other costs of presenting its case to the Independent Expert. Each party shall bear one-half of the costs and expenses of the Independent Expert.

 

(c)The parties shall adjust the Purchase Price to reflect the Environmental Defect Amounts, as agreed by the parties or as determined by the Independent Expert, for all Material Environmental Defects; provided, that notwithstanding anything to the contrary, (a) in no event shall there be any adjustments to the Purchase Price for any individual uncured Environmental Defect for

which the Environmental Defect Amount therefor does not exceed $100,000 (“Individual Environmental Threshold”); and (b) in no event shall there be any adjustments to the Purchase Price for any Material Environmental Defect unless the aggregate Environmental Defect Amount attributable to all Material Environmental Defects exceeds Six Million Dollars ($6,000,000) (the “Environmental Defect Deductible”), after which point Purchaser shall be entitled to adjustments to the Purchase Price or other remedies only to the extent the aggregate Environmental Defect Amounts with respect to all Material Environmental Defects are in excess of the Environmental Defect Deductible. To the extent the Independent Expert fails to determine any disputed Environmental Defect Amounts prior to Closing, then, within ten (10) days after the Independent Expert delivers written notice to Purchaser and Seller of his award with respect to an Environmental Defect Amount, Seller shall pay to Purchaser the amount, if any, so awarded by the Independent Examiner, plus interest payable on such amount at the Agreed Interest Rate from (but not including) the Closing Date to (and including) the date on which such amount is paid to Purchaser.

Until the Closing,

(a)Purchaser shall use reasonable efforts to notify Seller within two (2) Business Days after Purchaser obtains actual knowledge that any representation or warranty of Seller contained in this Agreement is untrue in any material respect or will be untrue in any material respect as of the Closing Date, or that any covenant or agreement to be performed or observed by Seller prior to or on the Closing Date has not been so performed or observed in any material respect. Any such notice shall include (i) a description of the instances Purchaser alleges have caused the representations or warranties of Seller to be untrue or have caused Seller's failure to perform or observe any covenant or agreement and the alleged value of such instances and (ii) a description of the actions Purchaser believes are necessary to cure the instances Purchaser alleges to have caused such representations and warranties to be untrue or have caused Seller's failure to perform or observe any covenant or agreement. Notwithstanding the foregoing, the failure of Purchaser to give Seller any such notice shall not constitute a breach of this Agreement so long as Seller's ability to cure is not materially harmed by Purchaser's failure to provide such notice.

  

(b)Seller shall use reasonable efforts to notify Purchaser within two (2) Business Days after Seller obtains actual knowledge that any representation or warranty of Purchaser contained in this Agreement is untrue in any material respect or will be untrue in any material respect as of the Closing Date, or that any covenant or agreement to be performed or observed by Purchaser prior to or on the Closing Date has not been so performed or observed in any material respect.

Notwithstanding the foregoing, the failure of Seller to give Purchaser any such notice shall not constitute a breach of this Agreement so long as Purchaser's ability to cure is not materially harmed by Seller's failure to provide such notice.

(c)If any of Purchaser's or Seller's representations or warranties is untrue or shall become untrue in any material respect between the date of execution of this Agreement and the Closing Date, or if any of Purchaser's or Seller's covenants or agreements to be performed or observed prior to or on the Closing Date shall not have been so performed or observed in any material respect, but if such

breach of representation, warranty, covenant or agreement shall (if curable) be cured by the Closing, then such breach shall be considered not to have occurred for all purposes of this Agreement. No such notification shall affect the representations or warranties of the parties or the conditions to their respective obligations hereunder.

(d)There shall be no breach of the covenants in this Section 7.3 as a result of a party's failure to report a breach of any representation or warranty or a failure to perform or observe any covenant or agreement of which it had knowledge if the party subject to the breach or failure also had knowledge thereof prior to Closing.

At or after Closing, the content of any press release or public announcement first announcing the consummation of this transaction shall be subject to the prior review and reasonable approval of Seller and Purchaser; provided, however, the foregoing shall not restrict disclosures by Purchaser or Seller which are required by applicable securities or other laws or regulations or the applicable rules of any stock exchange having jurisdiction over the disclosing party or its Affiliates.

Section 7.6    Operation of Business.

Except as set forth on Schedule 7.6, until the Closing, Seller (i) will operate the Assets and the business thereof as a reasonably prudent operator would operate, (ii) will not, without the prior written consent of Purchaser, which consent shall not be unreasonably withheld or delayed, commit to any operation, or series of related operations thereon, reasonably anticipated to require capital expenditures by Purchaser as owner of the Assets in excess of $125,000 (net to Seller's interest), or make any capital expenditures in respect of the Assets in excess of $125,000 (net to Seller's interest), or terminate, materially amend, execute or extend any material Contracts affecting the Assets, (iii) will use commercially reasonable efforts to maintain insurance coverage on the Assets presently furnished by nonaffiliated third parties in the amounts and of the types presently in force, (iv) will use commercially reasonable efforts to maintain in full force and effect all Leases, (v) will maintain all material governmental permits and approvals affecting the Assets, (vi) will not transfer, farmout, sell, encumber or otherwise dispose of any Assets, except for sales and dispositions of Hydrocarbon production in the ordinary course of business consistent with past practices, (vii) will not enter into any farmout or farmin affecting the Assets, (viii) will not make any non-consent elections with respect to operations affecting the Assets, (ix) will not relinquish any operating rights or other rights with respect to the Assets, (x) will not enter into any agreement that would constitute a Contract of the type specified in Section 5.10, (xi) will not subject any of the Assets to any partnership within the meaning of subchapter K of Chapter 1 of Subtitle A of the Code, (xii) will not settle or compromise any claim or proceeding, or waive or extend any period of limitations attributable to any of the Assets, and (xiii) will not commit to do any of the foregoing. Purchaser's approval of any action restricted by this Section 7.6 shall be considered granted within ten (10) days (unless a shorter time is reasonably required by the circumstances and such shorter time is specified in Seller's written notice) of Seller's written notice to Purchaser requesting such consent unless Purchaser notifies Seller to the contrary in writing during that period. In the event of an emergency, Seller may take such action as a prudent operator would take and shall notify Purchaser of such action promptly thereafter.

Purchaser acknowledges that Seller may own an undivided interest in certain of the Assets, and Purchaser agrees that the acts or omissions of the other Working Interest owners who are not affiliated with Seller shall not constitute a violation of the provisions of this Section 7.6 nor shall any action required by a vote of Working Interest owners constitute such a violation so long as Seller has voted its interest in a manner consistent with the provisions of this Section 7.6.

Section 7.7    Preference Rights and Transfer Requirements.

(a)The transactions contemplated by this Agreement are expressly subject to all validly existing and applicable Preference Rights and Transfer Requirements. Prior to the Closing Date, Seller shall initiate all procedures which are reasonably required to comply with or obtain the waiver of all Preference Rights and Transfer Requirements set forth in Schedule 7.7 with respect to the transactions contemplated by this Agreement. Seller shall use its commercially reasonable efforts to satisfy all applicable Transfer Requirements set forth in Schedule 7.7 and to obtain waivers of all applicable Preference Rights set forth in Schedule 7.7. Seller shall advise Purchaser of, and Seller shall not be obligated to pay, any consideration to (or incur any cost or expense for the benefit of) the holder of any Preference Right or Transfer Requirement in order to obtain the waiver thereof or compliance therewith.

(b)If the holder of a Preference Right elects prior to Closing to purchase the Asset subject to a Preference Right (a “Preference Property”) in accordance with the terms of such Preference Right, and Seller receives timely written notice of such election prior to the Closing, then the Preference Property shall be sold to the exercising party on the same terms and conditions provided in this Agreement, such Preference Property will be eliminated from the Assets and the Purchase Price shall be reduced by the Allocated Value of the Preference Property.

(c)If:

then, unless otherwise agreed by Seller and Purchaser, the Asset or portion thereof affected by such Preference Right or Transfer Requirement (a “Retained Asset”) shall be held back from the Assets to be transferred and conveyed to Purchaser at Closing and the Purchase Price to be paid at Closing shall be reduced by the Allocated Value of such Retained Asset pursuant to Section 7.7(b). Any Retained Asset so held back at the initial Closing will be conveyed to Purchaser at a delayed Closing (which shall become the new Closing Date with respect to such Retained Asset) within ten (10) days following the date on which the suit, action or other proceeding, if any, referenced in clause (i) above is settled or a judgment is rendered (and no longer subject to appeal) permitting transfer of the Retained Asset to Purchaser pursuant to this Agreement and Seller obtains, complies with, obtains a waiver of or notice of election not to exercise or otherwise satisfies all remaining Preference Rights and Transfer Requirements with respect to such Retained Asset as contemplated by this Section 7.7 (or if multiple Assets are Retained Assets, on a date mutually agreed to by the parties in order to consolidate, to the extent reasonably possible, the number of Closings). At the delayed Closing, Purchaser shall pay Seller a purchase price equal to the amount by which the Purchase Price was reduced on account of the holding back of such Retained Asset (as adjusted pursuant to Section 2.2 through the new Closing Date therefor); provided, however, if all such Preference Rights and Transfer Requirements with respect to any Retained Asset so held back at the initial Closing are not obtained, complied with, waived or otherwise satisfied as contemplated by this Section 7.7 on or before the Final Settlement Date, then such Retained Asset shall be eliminated from the Assets and shall become an Excluded Asset, unless Seller and Purchaser mutually agree otherwise.

(d)Purchaser acknowledges that Seller desires to sell all of the Assets to Purchaser and would not have entered into this Agreement but for Purchaser's agreement to purchase all of the Assets as herein provided. Accordingly, it is expressly understood and agreed that Seller does not desire to sell any Property affected by a Preference Right to Purchaser unless the sale of all of the Assets is consummated by the Closing Date in accordance with the terms of this Agreement. In furtherance of the foregoing, Seller's obligation hereunder to sell the Preference Properties to Purchaser is expressly conditioned upon the consummation by the Closing Date of the sale of all of the Assets (other than Retained Assets or other Assets excluded pursuant to the express provisions of this Agreement) in accordance with the terms of this Agreement, either by conveyance to Purchaser or conveyance pursuant to an applicable Preference Right; provided that, nothing herein is intended or shall operate to extend or apply any Preference Right to any portion of the Assets which is not otherwise burdened thereby. Time is of the essence with respect to the parties' agreement to consummate the sale of the Assets by the Closing Date (or by the delayed Closing Date pursuant to Section 7.7(c)).

Section 7.8    Suspense Accounts.

Schedule 7.8 sets forth a true and complete amount, as of March 1, 2012, of all third party proceeds of production from the Assets being held in suspense by Seller (other than the Anderson Escrow). Prior to Closing, Seller shall prepare a schedule setting forth the following information: (i) all proceeds of production attributable to the Assets held by Seller in suspense, (ii) a description of the reason such proceeds are being held in suspense (to the extent such information is available to Seller; provided, however, such description shall in no way be deemed a representation or warranty regarding the accuracy or validity of any such description), and (iii) if known, the name or names of the persons claiming such proceeds. Notwithstanding anything herein to the contrary including without limitation Section 11.4, to the extent Purchaser receives a reduction in the Purchase Price pursuant to this Agreement for such suspense funds, Purchaser agrees to indemnify Seller against any claim relating to the failure to pay such fund after Closing.

Section 7.9    Tax Matters.

(a)The Parties acknowledge that Property Taxes assessed with respect to the Assets are measured by the value of the preceding year's production. Notwithstanding the forgoing, however, Property Taxes shall be apportioned between the Parties in accordance with the relative ownership periods pre- and post-Effective Times. 2012 Property Taxes, payable in 2013, are based on the value of 2011 production but shall be allocated between Seller and Purchaser in accordance with their proportionate ownership periods before and after the Effective Date (notwithstanding the fact that such taxes are based on 2011 production). 2013 Property Taxes, payable in 2014, shall be borne entirely by Purchaser as the owner of the Assets during 2013 notwithstanding the fact that such Property Taxes are based on 2012 production. Each Party shall promptly furnish to the other copies of any Property Tax assessments and statements (or invoices therefor from the operator of the Assets) received by it pertaining to an Asset.

(b)Severance Taxes shall be deemed attributable to the period during which the production of the Hydrocarbons with respect to such Severance Taxes occurred, and liability therefor shall be allocated to Seller for pre-Effective Time Severance Taxes and to Purchaser for post-Effective Time Severance Taxes, without duplicating any adjustment to the Purchase Price pursuant to Section 2.2.

Severance Taxes for the taxable year 2012 shall be estimated immediately prior to Closing based on 2012 State of Colorado Severance Tax rates.

(c)Any Taxes apportioned under Section 7.9(a) and Section 7.9(b) (to the extent applicable and to the extent the actual amounts differ from the estimates included in the Preliminary Closing Statement and are known at the time of the Final Settlement Statement) shall be accounted for in the Final Settlement Statement. For the purpose of calculating the Final Purchase Price under Section 9.4(b), Property Taxes determined by 2011 production (and payable in 2013) shall be estimated based on then-current mill levies and the production occurring prior to the Effective Date, with the Purchase Price adjustment to be considered full and final settlement of all such taxes. If the actual amounts are not known at the time of the Final Closing Statement, the amounts shall be re-estimated based on the best information available at the time of the Final Closing Statement, and such amounts shall thereupon become final for purposes of this Agreement.

(d)After the Closing Date, each of Purchaser and Seller shall

Seller shall make payment to the appropriate Governmental Body of all Taxes with respect to the Assets which are required to be paid on or prior to the Closing Date and shall file all Tax Returns that are required to be filed on or prior to the Closing Date (without regard to any extension requested or granted with respect to such Tax Return). Purchaser shall make payment to the appropriate Governmental Body of all Taxes with respect to the Assets which are required to be paid after the Closing Date and shall file all Tax Returns for Taxes treated as Property Costs that are required to be filed after the Closing Date, except as described in the previous sentence.

Section 7.10    Further Assurances.

(a)After Closing, Seller and Purchaser each agrees to take such further actions and to execute, acknowledge and deliver all such further documents as are reasonably requested by the other party for carrying out the purposes of this Agreement or of any document delivered pursuant to this Agreement.

(b)From the date of execution of this Agreement until the Closing, Seller will cooperate and assist Purchaser in the transition of regulatory production reporting and revenue accounting for the Assets. In addition, at the request of Purchaser, Seller will continue, following the Closing, to provide regulatory production reporting and revenue disbursement accounting services for Purchaser as they relate to the Assets and the production months prior to and through the month of Closing. Purchaser will notify Seller at least ten (10) days prior to Closing in the event Purchaser desires Seller to continue providing such production reporting and revenue accounting services (or any other similar administrative services) for the Assets for production months following the Closing. In the event of any such notice, the Parties agree to attempt to negotiate a mutually acceptable transition services agreement (provided, however, that neither Party shall have any liability to the other in the event they are unable to reach an agreement for the provision of such transition services).

Section 7.11    Insurance.

(a)On or before the Closing Date, Purchaser shall provide Seller with certificates of insurance evidencing the following insurance carried by Purchaser with respect to the Assets: (i) general liability insurance with combined single limits per occurrence of not less than One Million Dollars ($1,000,000) for bodily injury and property damage, including property damage by blowout and cratering, completed operations, and contractual liability as respects any contract into which Purchaser may enter under the terms of this Agreement; (ii) operators extra expense insurance with limits of not less than Twenty-Five Million Dollars ($25,000,000) per occurrence, covering the costs of controlling a blowout, and certain other related and/or resulting costs and seepage and pollution liability, and (iii) any other policies identified in Section 4.1(f).

(b)On or before the execution of this Agreement, Seller has provided Purchaser with certificates of insurance evidencing the following insurance carried by Seller with respect to the Assets: (i) general liability insurance with combined single limits per occurrence of not less than Five Million Dollars ($5,000,000) for bodily injury and property damage, including property damage by blowout and cratering, completed operations, and contractual liability as respects any contract into which Seller may enter under the terms of this Agreement; and (ii) operators extra expense insurance with limits of not less than Twenty Million Dollars ($20,000,000) per occurrence, covering the costs of controlling a blowout, and certain other related and/or resulting costs and seepage and pollution liability. Seller shall maintain such insurance in full force and effect until Closing.

Section 7.12    No Solicitation of Transactions.

Seller shall not, directly or indirectly, through any officer, director, stockholder, employee, agent, financial advisor, banker or other representative or Affiliate, or otherwise, solicit, initiate, or encourage the submission of any proposal or offer from any Person relating to any acquisition or purchase of all or any portion of the Assets or participate in any negotiations regarding, or furnish to

any other Person any information with respect to, or otherwise cooperate in any way with, or assist or participate in, facilitate, or encourage, any effort or attempt by any other Person to do or seek any of the foregoing. Seller shall communicate as soon as reasonably practicable to Purchaser the material terms of any such proposal (and the identity of the party making such proposal) which it may receive and, if such proposal is in writing, Seller shall promptly deliver a copy of such proposal to Purchaser. Seller agrees not to release any third party from, or waive any provision of, any confidentiality agreement relating to the Assets to which Seller or any of its Affiliates is a party. Seller immediately shall cease and cause to be terminated all existing discussions or negotiations with any parties conducted heretofore with respect to any of the foregoing.

Section 7.13    Record Retention.

Purchaser, for a period of seven (7) years following Closing, will (i) retain the Records, (ii) provide Seller, its Affiliates and its and their officers, employees and representatives with access to the Records (to the extent that Seller has not retained the original or a copy) during normal business hours for review and copying at Seller's expense and upon reasonable notice, and (iii) provide Seller, its Affiliates and its and their officers, employees and representatives with access, during normal business hours, to materials received or produced after Closing relating to any indemnity claims made under Section 11.4 and Section 11.5 of this Agreement for review and copying at Seller's expense; provided, however, that Purchaser shall not be required to grant access to Seller or any of its representatives, consultants or advisors, to any Records that are subject to an attorney/client or attorney work product privilege or that would cause Purchaser to violate any obligation to any third party or breach any restriction legally binding on Purchaser. Any such access shall be at the sole cost and expense of Seller. Unless otherwise consented to in writing by Seller, for a period of seven (7) years following the Closing Date, Purchaser shall not and shall cause its Affiliates not to, destroy, alter or otherwise dispose of the Records, or any portions thereof, without first giving at least thirty (30) days prior written notice to Seller and offering to surrender to Seller the Records or such portions thereof.

Section 7.14    Audit Rights.

Seller shall use commercially reasonable efforts to cooperate with Purchaser and make available, during normal business hours, to Purchaser and its representatives prior to and for a period of fifteen (15) months following the Closing any and all existing information and documents relating to revenues and expenses attributable to the Assets and in the possession of Seller (subject to the rights of third parties) that Purchaser may reasonably require to comply with Purchaser's tax and financial reporting requirements and audits, including any filings with any Governmental Entity and filings that may be required by the Securities and Exchange Commission under the Securities Act of 1933 and/or the Securities Exchange Act of 1934. Seller's cooperation will include (a) reasonable access during normal business hours to Seller's employees and representatives designated by Seller who were responsible for preparing or maintaining the revenue and expense records and work papers and other supporting documents used in the preparation of such financial statements as may be required by Purchaser's independent auditors to perform an audit or conduct a review in accordance with generally accepted auditing standards or to otherwise verify such financial statements; and (b) delivery of one or more customary representation letters from Seller to Purchaser's independent auditors that are reasonably requested by Purchaser to allow such auditors to complete an audit (or review of any financial statements), and to allow Purchaser's independent auditors to issue an opinion with respect

to its audit or review. Purchaser will pay or, if paid, reimburse Seller, within ten (10) Business Days after demand therefor, for any reasonable out-of-pocket and overhead costs incurred by Seller in complying with the provisions of this Section 7.14.

Section 7.15    Bonds, Letters of Credit and Guarantees.

Purchaser acknowledges that none of the bonds, letters of credit and guarantees, if any, posted by Seller or its Affiliates with Governmental Authorities or third parties and relating to the Assets are transferable to Purchaser. Except to the extent that Purchaser will, as of Closing, be covered by the bonds of the operators of the applicable Assets, then on or before the Closing Date, Purchaser shall obtain, or cause to be obtained in the name of Purchaser, replacements for such bonds, letters of credit and guarantees, to the extent such replacements are necessary to permit the cancellation as of Closing of the bonds, letters of credit and guarantees posted by Seller and/or its Affiliates.

Section 7.16    Cure of Misrepresentations.

Section 7.19    Employee Matters.

(a)Seller shall provide a list of Business Employees to Purchaser at least fifteen (15) Business Days prior to the Closing Date and shall update such list on and through the Closing Date to reflect any new hires or departures. Purchaser may make an offer of employment to such Business

Employees as it chooses in its sole and absolute discretion, with such offers to be effective as of the Closing Date (or such later date as any Business Employee who is on short or long term disability may be ready to return to work).

(b)For purposes of this Agreement, a “New Employee” is a Business Employee who accepts an offer of employment made pursuant to Section 7.19(a).

(c)Purchaser shall take such actions as are necessary to provide each New Employee with credit for up to five (5) years of service for Seller and its ERISA Affiliates (including, without limitation, Merit Energy Company, LLC) for purposes of eligibility, vesting, and entitlement to benefits (and for benefit accruals solely with respect to vacation, sick leave, and severance), under all employee benefit plans (as defined in section 3(3) of ERISA) and all vacation, sick leave, severance, and other compensation plans, policies, agreements and arrangements maintained by the Purchaser or any of its Affiliates in which such New Employee participates on or after the Closing Date in the same manner as if such service had been service for Purchaser completed after the Closing.

(d)Purchaser shall take such actions as are necessary to offer medical and dental coverage for New Employees and their spouses and dependents under Purchaser's group health plan (the “Group Health Plan”). Purchaser shall use best efforts to cause each such Group Health Plan, and applicable insurance carriers, third party administrators and any other third parties, to (i) waive any waiting period(s) under the Group Health Plan otherwise applicable to such New Employees, (ii) waive all limitations as to pre-existing medical conditions under the Group Health Plan applicable to New Employees to the extent that such medical conditions would be covered under the Group Health Plan if they were not pre-existing conditions, and (iii) provide New Employees with credit, for the year in which the Closing Date occurs, for any co-payments and deductibles paid prior to the Closing Date in satisfying any applicable co-payment and deductible requirements under the Group Health Plan.

(e)Purchaser shall take such actions as are necessary to cause New Employees to participate in any incentive bonus programs in which similarly situated employees of Purchaser or its Affiliates participate.

(f)With respect to events following the Closing, Purchaser shall be responsible for sending timely and appropriate notices to all New Employees required under the Worker Adjustment and Retraining Notification Act (“WARN”) and all other applicable Laws relating to plant or facility closings or otherwise regulating the termination of employees.

(g)Seller shall make available to Purchaser records which provide information regarding New Employees' names and dates of hire by Seller or its Affiliates and that contain such information as is necessary for Purchaser to meet its obligations under this Section 7.19. Seller shall not provide

(h)Following the Closing, Purchaser shall use commercially reasonable efforts to cause to be accepted by the trustee of a Purchaser Retirement Plan in which a New Employee is eligible to participate or a rollover of any eligible rollover distribution (within the meaning of section 402(c) of the Code) of such New Employee's benefit under a Seller Retirement Plan provided that Seller provides to Purchaser such information as is satisfactory to Purchaser to assure itself that such Seller Retirement Plan satisfies the qualification requirements of section 401(a) of the Code.

(i)Purchaser agrees that, for a period of twelve (12) months following Closing, Purchaser will not, in any manner, directly or indirectly, solicit any person who is an employee of Seller (other than any Business Employee) to apply for or accept employment with Purchaser or any other business entity, or discuss with any person who is an employee of Seller (other than any Business Employee) alternative employment with Purchaser or any other business entity. Notwithstanding the foregoing, it shall not constitute a violation of this Section 7.19(i) for Purchaser to (A) make a general solicitation for employment or other services through any form of media or any third party recruiting firm not specifically directed to the employees, agents or consultants of Seller and hire any person that responds to the same, (B) solicit or hire any person who initiates discussions with Purchaser regarding employment without any direct or indirect prohibited solicitation by Purchaser, or (C) solicit or hire any person who has ceased to be employed by Seller prior to commencement of employment discussions between Purchaser and such person.

(a)the Conveyances in sufficient duplicate originals to allow recording in all appropriate jurisdictions and offices, duly executed by Seller;

(f)any other agreements, instruments and documents which are required by other terms of this Agreement to be executed and/or delivered at Closing.

Section 9.4    Closing Adjustments and Closing Payment.

(a)Not later than five (5) Business Days prior to the Closing Date, Seller shall prepare and deliver to Purchaser, based upon the best information available to Seller, a preliminary settlement statement, together with supporting documentation, estimating the Adjusted Purchase Price after giving effect to all adjustments listed in Section 2.2 and Section 2.3 (the “Preliminary Closing Statement”). The estimate delivered in accordance with this Section 9.4(a) shall constitute the dollar amount to be paid by Purchaser to Seller at the Closing (the “Closing Payment”). Until one (1) Business Day before the Closing Date, (i) Purchaser shall have the opportunity to review and discuss the Preliminary Closing Statement with Seller, and (ii) if Purchaser notifies Seller on or before such date that it disputes Seller's estimate of the Adjusted Purchase Price and the parties cannot agree on the estimate of the Adjusted Purchase Price, then the Adjusted Purchase Price paid at Closing shall be the amount that is midway between Seller's and Purchaser's estimated amounts and such amount shall be deemed to be the Closing Payment.

(b)As soon as reasonably practicable after the Closing but not later than one hundred eighty (180) days following the Closing Date, Seller shall prepare and deliver to Purchaser a statement (the “Final Closing Statement”) setting forth the final calculation of the Agreed Purchase Price and showing the calculation of each adjustment, based, to the extent possible, on actual credits, charges, receipts and other items before and after the Effective Time and taking into account all adjustments provided for in this Agreement (the “Final Purchase Price”). Seller shall, at Purchaser's request, supply reasonable documentation available to support any credit, charge, receipt or other item. Seller shall afford Purchaser and its representatives the opportunity to review such statement and the supporting schedules, analyses, work papers, and other underlying records or documentation as are reasonably necessary and appropriate in Purchaser's review of such statement. Each party shall cooperate fully and promptly with the other and their respective representatives in such examination with respect to all reasonable requests related thereto. As soon as reasonably practicable but not later than sixty (60) days following receipt of Seller's statement hereunder, Purchaser shall deliver to Seller a written report containing any changes that Purchaser proposes be made to such statement. Seller and Purchaser shall undertake to agree on the final statement of the Final Purchase Price no later than thirty (30) days after receipt of Purchaser's written report containing recommended changes (the “Final Settlement Date”). Unless the parties are unable to reach agreement on the Final Closing Statement on or before the Final Settlement Date, then on the Final Settlement Date, (x) Purchaser shall pay to Seller the amount by which the Final Purchase Price exceeds the Closing Payment or (y) Seller shall pay to Purchaser the amount by which the Closing Payment exceeds the Final Purchase Price, as applicable (in either case, the “Final Adjustment”).

(c)In the event that Seller and Purchaser cannot reach agreement by the Final Settlement Date, either party may refer the remaining matters in dispute to Grant Thornton LLP or a nationally-

recognized independent accounting firm as may be mutually accepted by Purchaser and Seller, for review and final determination (the “Agreed Accounting Firm”). If issues are submitted to the Agreed Accounting Firm for resolution, Seller and Purchaser shall each enter into a customary engagement letter with the Agreed Accounting Firm at the time the issues remaining in dispute are submitted to the Agreed Accounting Firm. The Agreed Accounting Firm will be directed to (i) review the statement setting forth Seller's calculation of the Final Purchase Price and the records relating thereto only with respect to items identified by Purchaser in its written report containing changes to such statement that remain disputed immediately following the Final Settlement Date and (ii) determine the final adjustments. Each party shall furnish the Agreed Accounting Firm such work papers and other records and information relating to the objections in dispute as the Agreed Accounting Firm may reasonably request and that are available to such party or its Affiliates (and such parties' independent public accountants). The parties will, and will cause their representatives to, cooperate and assist in the conduct of any review by the Agreed Accounting Firm, including, but not limited to, making available books, records and, as available, personnel as reasonably required. The Agreed Accounting Firm shall conduct the arbitration proceedings in Dallas, Texas in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section 9.4. The Agreed Accounting Firm's determination shall be made within thirty (30) days after submission of the matters in dispute and shall be final and binding on both parties, without right of appeal and such decision shall constitute an arbitral award upon which a judgment may be entered by a court having jurisdiction thereof. In determining the proper amount of any adjustment to the Final Purchase Price, the Agreed Accounting Firm shall not increase the Final Purchase Price more than the increase proposed by Seller nor decrease the Final Asset Value more than the decrease proposed by Purchaser, as applicable, and may not award damages or penalties to either party with respect to any matter. Seller and Purchaser shall each bear its own legal fees and other costs of presenting its case. Each party shall bear one-half of the costs and expenses of the accounting firm. Within ten (10) Business Days after the date on which the parties or the Agreed Accounting Firm, as applicable, finally determines the disputed matters, (x) Purchaser shall pay to Seller the amount by which the Final Purchase Price exceeds the Closing Payment or (y) Seller shall pay to Purchaser the amount by which the Closing Payment exceeds the Final Purchase Price, as applicable. Any post-Closing payment pursuant to this Section 9.4(b) shall bear interest at the Agreed Interest Rate from (but not including) the Closing Date to (and including) the date both Purchaser and Seller have executed the Final Closing Statement. The Parties acknowledge that it is not the intent of this Agreement that either Party be deprived of material amounts of revenue or be burdened by material amounts of expense until the Final Adjustment pursuant to Section 9.4(a). If at any time after Closing either Party is owed material revenues or material expense reimbursement, which revenues and expense reimbursement owed shall be netted against revenues and expenses due the other Party, it may request payment from the other Party, not more frequently than monthly, and such Party shall make payment of any undisputed amounts within a commercially reasonable period of time. For purposes of the immediately preceding sentence only, material shall mean an amount in excess of $5,000,000.

(d)All payments made or to be made hereunder to Seller shall be by electronic transfer of immediately available funds to the account of Seller as may be specified by Seller in writing. All payments made or to be made hereunder to Purchaser shall be by electronic transfer of immediately available funds to a bank and account specified by Purchaser in writing to Seller. Upon execution of the Final Closing Statement by the parties and the payment of the Final Adjustment by one party

to the other, neither party shall have any further obligation to for any additional adjustments to the Purchase Price under Section 2.2.

Section 10.1    Termination.

This Agreement may be terminated and the transactions contemplated hereby abandoned at any time prior to the Closing:

(a)by mutual written consent of Seller and Purchaser;

(b)by either Seller or Purchaser, if:

(c)by Seller, if Seller's conditions set forth in Section 8.1(a), (b), (d), (g) or (h) are not satisfied or are not capable of satisfaction through no fault of Seller, or are not waived by Seller, as of the Closing Date; provided that, if curable, the underlying breach of such representation or warranty or failure to perform such covenant or agreement has not been cured within ten (10) days after written notice thereof from Seller to Purchaser; provided further that any cure period shall not extend beyond the Termination Date and shall not extend the Termination Date; or

(d)by Purchaser, if Purchaser's conditions set forth in Section 8.2(a), (b) or (d) are not satisfied or are not capable of satisfaction through no fault of Seller, or are not waived by Seller, as of the Closing Date; provided that, if curable, the underlying breach of such representation or warranty or failure to perform such covenant or agreement has not been cured within ten (10) days after written notice thereof from Purchaser to Seller; provided further that any cure period shall not extend beyond the Termination Date and shall not extend the Termination Date.

(e)By Seller, if the conditions set forth in Sections 8.1(e) or 8.1(f) are not satisfied at any

time prior to the Closing Date.

(f)By Purchaser, if the conditions set forth in Sections 8.2(e) or 8.2(f) are not satisfied at any time prior to the Closing Date.

Section 10.2    Effect of Termination.

If this Agreement is terminated pursuant to Section 10.1, this Agreement shall become void and of no further force or effect (except for the provisions of Section 4.4, Section 5.6, Section 6.5, Section 7.5, 11.4, 11.5, 11.6 and 11.7 of this Agreement and this Article 10, the Section entitled “Definitions,” and Article 12, all of which shall continue in full force and effect). Notwithstanding the foregoing, nothing contained in this Section 10.2 shall relieve any party from liability for Losses resulting from its breach of this Agreement.

Section 10.3    Distribution of Deposit Upon Termination.

(a)If Seller terminates this Agreement pursuant to Section 10.1(c), then Seller shall be entitled to retain the Deposit, as its sole and exclusive remedy as liquidated damages, free of any claims by Purchaser or any other Person with respect thereto. It is expressly stipulated by the parties that the actual amount of damages resulting from such a termination would be difficult if not impossible to determine accurately because of the unique nature of this Agreement, the unique nature of the Assets, the uncertainties of applicable commodity markets and differences of opinion with respect to such matters, and that the liquidated damages provided for herein are a reasonable estimate by the parties of such damages.

(b)If this Agreement is terminated for any reason other than the reasons set forth in Section 10.3(a), then Purchaser shall be entitled to receive the Deposit free of any claims by Seller or any other Person with respect thereto after Purchaser has satisfied any remaining obligations hereunder. If Purchaser terminates this Agreement pursuant to Section 10.1(d), provided that such termination is not determined by a trier of fact in a finally adjudicated proceeding to be wrongful, then Purchaser shall retain any legal or equitable remedies for Seller's breach of this Agreement, including, without limitation, specific performance. Notwithstanding anything to the contrary in this Agreement, Purchaser shall be entitled to receive any interest actually accrued on the Deposit if the Deposit is returned to Purchaser pursuant to this Section 10.3(b).

Section 11.1    Purchaser's Assumption of Liabilities and Obligations.

Subject to the indemnification by Seller under Section 11.4, on the Closing Date, Purchaser shall assume and hereby agrees to fulfill, perform, pay and discharge (or cause to be fulfilled, performed, paid or discharged) all claims, expenses, liabilities and obligations relating to (a) the owning, developing, exploring, operating or maintaining of the Assets or the producing, transporting and marketing of Hydrocarbons from the Assets (including Property Costs) for all periods prior to

and after the Effective Time, excluding the Interim Operations Liabilities (defined in Section 11.2), including, without limitation, the payment of royalties, overriding royalties and Taxes; (b) Environmental Liabilities whether arising before or after the Effective Time; (c) the P&A Obligations, (d) the payment of pre and post-Effective Time production sale revenues attributable to working interests, royalties, overriding royalties and other interests held in suspense and for which a reduction to the Purchase Price is made, and (e) the restoration and reclamation of the premises covered by or related to the Assets to the extent required by applicable agreements and Laws (all of said obligations and liabilities, subject to the exclusions below, herein being referred to as the “Purchaser's Assumed Obligations”); provided, however, that the Purchaser's Assumed Obligations shall not include, and Purchaser shall have no obligation to assume, any obligations or liabilities of Seller to the extent that they are Seller's Retained Obligations.

Section 11.2    Seller's Retention of Liabilities and Obligations.

Upon Closing, Seller retains all claims, costs, expenses, liabilities and obligations accruing or relating to (a) for the Non-Fundamental Survival Period only, the owning, developing, exploring, operating or maintaining of the Assets or the producing, transporting and marketing of Hydrocarbons from the Assets (including Property Costs) prior to the Effective Time, except for Environmental Liabilities, but including without limitation the payment of royalties, overriding royalties and Taxes attributable to the period of time prior to the Effective Time or measured by production occurring prior to the Effective Time (“Interim Operations Liabilities”); (b) any personal injury or death, prior to the Closing Date, (c) the Excluded Assets, (d) Retained Employee Liabilities, (e) any Income Tax measured by or imposed on the net income of Seller or any of its Affiliates that was or is attributable to Seller's or any of its Affiliate's ownership or an interest in or the operation of the Assets, and (f) the payment of any amounts attributable to royalties or other interests from the Anderson Escrow, all of said obligations and liabilities herein being referred to as the “Seller's Retained Obligations.”

Section 11.3    Survival.

(a)All representations and warranties of Seller and Purchaser contained herein (“Representations”) and Seller's retention of the Interim Operations Liabilities shall survive for one (1) year after the Closing Date (the “Non-Fundamental Survival Period”); provided, however, that the Representations contained in Section 5.3, Section 5.4, Section 5.6, Section 6.2, Section 6.3, Section 6.5 and Section 6.11 (collectively, the “Fundamental Representations”) shall survive until the expiration of the applicable statute of limitations period (the “Fundamental Survival Period”; and together with the Non-Fundamental Survival Period, the “Survival Period”); and (iii) the Representations contained in Section 5.27 shall terminate on the Closing Date. Upon the termination of a Representation in accordance with the foregoing, such Representation shall have no further force or effect for any purpose under this Agreement. The covenants and other agreements of Seller and Purchaser set forth in this Agreement shall survive the Closing Date until fully performed.

(b)No party hereto shall have any indemnification obligation pursuant to this Article 11 or otherwise hereunder unless it shall have received from the party seeking indemnification a written notice (a “Claim Notice”) of the existence of the claim for or in respect of which indemnification is being sought hereunder on or before the expiration of the applicable Survival Period set forth in Section 11.3(a). If an Indemnified Party delivers a Claim Notice with respect to a representation or

warranty to an Indemnifying Party before the expiration of the applicable Survival Period set forth in Section 11.3(a), then the applicable representation or warranty shall survive until, but only for purposes of, the resolution of the matter covered by such Claim Notice. A Claim Notice shall set forth with reasonable specificity (1) the basis for such claim under this Agreement, and the facts that otherwise form the basis of such claim and (2) to the extent reasonably estimable, an estimate of the amount of such claim (which estimate shall not be conclusive of the final amount of such claim) and an explanation of the calculation of such estimate.

Section 11.4    Indemnification by Seller.

From and after the Closing, subject to the terms and conditions of this Article 11 (including, without limitation, the survival and the timing requirement in Section 11.3), Seller shall jointly and severally indemnify, defend and hold harmless Purchaser and its directors, officers, employees, stockholders, members, and Affiliates and the successors and permitted assigns of this Agreement of Purchaser (collectively, the “Purchaser Indemnified Persons”) from and against any and all Losses asserted against, resulting from, imposed upon, or incurred or suffered by any Purchaser Indemnified Person to the extent resulting from, arising out of or relating to:

(a)subject to the applicable Survival Period, any breach of any Representation of Seller contained in this Agreement or confirmed in any certificate furnished by or on behalf of Seller in connection with this Agreement and any Interim Operations Liabilities REGARDLESS OF FAULT;

(b)any breach or nonfulfillment of or failure to perform any covenant or agreement of Seller contained in this Agreement REGARDLESS OF FAULT or confirmed in any certificate furnished by or on behalf of Seller in connection with this Agreement;

(c)the Seller's Retained Obligations (other than Interim Operations Liabilities) REGARDLESS OF FAULT; and

From and after the Closing, subject to the adjustments to the Purchase Price for purposes of the Closing Statements contained in Section 2.2 and the terms and conditions of this Article 11 (including, without limitation, the survival and timing requirements of Section 11.3), Purchaser shall indemnify, defend and hold harmless Seller, Seller's Affiliates, and each of their respective managers, general partners, partners, directors, officers, employees, equity owners, stockholders and Seller's predecessors-in-interest (all such persons referred to collectively as the “Seller Indemnified Persons”) from and against any and all Losses, asserted against, resulting from, imposed upon, or incurred or suffered by any Seller Indemnified Person, directly or indirectly, to the extent resulting from, arising out of, or relating to:

(e)any other indemnity obligations of Purchaser contained herein, including without limitation, Section 4.4.

Section 11.6    Indemnification Proceedings.

(a)In the event that any claim or demand for which Seller or Purchaser (such Person, an “Indemnifying Party”) may be liable to a Purchaser Indemnified Person under Section 11.4 or to an Seller Indemnified Person under Section 11.5 (an “Indemnified Party”) is asserted against or sought to be collected from an Indemnified Party by a third party (a “Third Party Claim”) the Indemnified Party shall with reasonable promptness notify the Indemnifying Party of such Third Party Claim by delivery of a Claim Notice, provided that the failure or delay to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Article 11, except (and solely) to the extent that the Indemnifying Party demonstrates that its defense of such Third Party Claim is actually and materially prejudiced thereby. The Indemnifying Party shall have thirty (30) days from receipt of the Claim Notice from the Indemnified Party (in this Section 11.6, the “Notice Period”) to notify the Indemnified Party whether or not the Indemnifying Party desires, at the Indemnifying Party's sole cost and expense, to defend the Indemnified Party against such claim or demand; provided, that the Indemnified Party is hereby authorized prior to and during the Notice Period, and at the cost and expense of the Indemnifying Party, to file any motion, answer or other pleading that it shall reasonably deem necessary to protect its interests or those of the Indemnifying Party. The Indemnifying Party shall have the right to assume the defense of such Third Party Claim only if and for so long as the Indemnifying Party (i) notifies the Indemnified Party during the Notice Period that the Indemnifying Party is assuming the defense of such Third Party Claim, (ii) uses counsel of its own choosing that is reasonably satisfactory to the Indemnified Party, and (iii) conducts the defense of such Third Party Claim in an active and diligent manner. If the Indemnifying Party is entitled to, and does, assume the defense of any such Third Party Claim, the Indemnified Party shall have the right to employ separate counsel at its own expense and to participate in the defense thereof; provided, however, that notwithstanding the foregoing, the Indemnifying Party shall pay the reasonable attorneys' fees of the Indemnified Party if the Indemnified Party's counsel shall have advised the Indemnified Party that there is a conflict of interest that could make it inappropriate under applicable standards of professional conduct to have common counsel for the Indemnifying Party and the Indemnified Party (provided that the Indemnifying Party shall not be responsible for paying for more than one separate firm of attorneys and one local counsel to represent all of the Indemnified Parties subject to such Third Party Claim). If the Indemnifying Party elects (and is entitled) to assume the defense of such Third Party Claim, (i) no compromise or settlement thereof or consent to any admission or the entry of any

judgment with respect to such Third Party Claim may be effected by the Indemnifying Party without the Indemnified Party's written consent (which shall not be unreasonably withheld, conditioned or delayed) unless the sole relief provided is monetary damages that are paid in full by the Indemnifying Party (and no injunctive or other equitable relief is imposed upon the Indemnified Party) and there is an unconditional provision whereby each plaintiff or claimant in such Third Party Claim releases the Indemnified Party from all liability with respect thereto and (ii) the Indemnified Party shall have no liability with respect to any compromise or settlement thereof effected without its written consent (which shall not be unreasonably withheld). If the Indemnifying Party elects not to assume the defense of such Third Party Claim (or fails to give notice to the Indemnified Party during the Notice Period or otherwise is not entitled to assume such defense), the Indemnified Party shall be entitled to assume the defense of such Third Party Claim with counsel of its own choice, at the expense and for the account of the Indemnifying Party; provided, however, that the Indemnified Party shall make no settlement, compromise, admission, or acknowledgment that would give rise to liability on the part of any Indemnifying Party without the prior written consent of such Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed.

(b)Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to control (but shall be entitled to participate at its own expense in the defense of), and the Indemnified Party, shall be entitled to have sole control over, the defense or settlement, compromise, admission, or acknowledgment of any Third Party Claim (i) at the reasonable expense of the Indemnifying Party, as to which the Indemnifying Party fails to assume the defense during the Notice Period after the Indemnified Party gives notice thereof to the Indemnifying Party or (ii) at the reasonable expense of the Indemnifying Party, to the extent the Third Party Claim seeks an order, injunction, or other equitable relief against the Indemnified Party which, if successful, could materially adversely affect the business, condition (financial or other), capitalization, assets, liabilities, results of operations or prospects of the Indemnified Party. The Indemnified Party shall make no settlement, compromise, admission, or acknowledgment that would give rise to liability on the part of the Indemnifying Party without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed).

(c)In any case in which an Indemnified Party seeks indemnification hereunder and no Third Party Claim is involved, the Indemnified Party shall deliver a Claim Notice to the Indemnifying Party within a reasonably prompt period of time after an officer of such Indemnified Party or its Affiliates has obtained knowledge of the Loss giving rise to indemnification hereunder. The failure or delay to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Article 11 except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively mitigate the resulting Losses or otherwise prejudices the Indemnifying Party.

Section 11.7    Limitations on Indemnities.

(a)Solely for purposes of calculating the amount of Losses incurred arising out of or relating to any breach or inaccuracy of a representation or warranty (and not for determining whether a breach has occurred), the references to “Material Adverse Effect” or other materiality qualifications (or correlative terms) shall be disregarded.

(b)Notwithstanding anything to the contrary in this Article 11 or otherwise, except with respect to Seller's obligations for post-closing adjustments to the Purchase Price and for matters arising out of or relating to Seller's Retained Obligations or breaches of Fundamental Representations, (i) Seller shall have no liability for any indemnification under Section 11.4 unless and until the amount of the liability for any individual Claim for which a Claim Notice is delivered by Purchaser exceeds $100,000 (each a “Material Indemnification Matter”), (ii) Seller shall not be obligated to indemnify the Purchaser Indemnified Persons pursuant to Section 11.4 unless and until the aggregate amount of all Losses incurred by Purchaser Indemnified Persons with respect to all Material Indemnification Matters exceeds Six Million Two Hundred Fifty Thousand Dollars ($6,250,000) (the “Indemnity Deductible”), in which event the Purchaser Indemnified Persons may recover all Losses incurred with respect to such Material Indemnification Matters in excess of the Indemnity Deductible, and (iii) Seller's maximum liability for Losses associated with all Material Indemnification Matters shall be thirty percent (30%) of the Purchase Price before any adjustments.
