14

(b) Subject to the provisions hereof (including Section 2.4(b)(iii) and the allocations contemplated thereby), and subject to the occurrence of Closing, Purchaser shall be entitled to all Hydrocarbon production from or attributable to the Assets at and after the Effective Time (and all products and proceeds attributable thereto), and to all other income, proceeds, receipts and credits earned with respect to the Assets at or after the Effective Time, and Purchaser shall be responsible for (and entitled to any refunds with respect to) all Property Costs incurred at and after the Effective Time. Subject to the provisions hereof, Seller shall be entitled to all Hydrocarbon production from or attributable to the Assets prior to the Effective Time (and all products and proceeds attributable thereto), and to all other income, proceeds, receipts and credits earned with respect to the Assets prior to the Effective Time, and Seller shall be responsible for (and entitled to any refunds with respect to) all Property Costs incurred by Seller prior to the Effective Time.

(i) As used in this Agreement, the terms “earned” and “incurred” shall be interpreted in accordance with GAAP and Council of Petroleum Accountants Society (“COPAS”) standards, as applicable. For purposes of this Section 2.4, determination of whether Property Costs are attributable to the period before or after the Effective Time shall be based on when services are rendered, when the goods are delivered, or when the work is performed.

(ii) As used in this Agreement, the term “Property Costs” means all operating costs attributable to the ownership and operation of the Assets (excluding without limitation Taxes) and capital expenditures incurred in the ownership and operation of the Assets and, where applicable, in accordance with the relevant operating or unit agreement or pooling order, if any, and overhead costs charged to the Assets under the relevant operating or unit agreement or pooling order, if any, and regardless of whether charged by an Affiliate of Seller or by a third party, but excluding damages attributable to (a) personal injury or death, property damage, torts, breach of contract, or violation of any Law, (b) obligations relating to the abandonment or plugging of Wells, dismantling or decommissioning facilities, closing pits and restoring the surface around such Wells, facilities and pits, (c) Environmental Liabilities, (d) obligations with respect to Imbalances, (e) obligations to pay royalties or other interest owners revenues or proceeds relating to the Assets but held in suspense, and (f) claims for indemnification or reimbursement from any third party with respect to costs of the types described in the preceding clauses (a) through (e), whether such claims are made pursuant to contract or otherwise.

(iii) For purposes of those Wells or Development Locations identified on Schedule 2.4, Schedule 2.4 (in the column labeled “Total Orig. Capex (Net)) details the costs to bring such wells on to production (including drilling, completion and related facilities) as reflected in all AFEs received by Seller on or before the Effective Time (the “Estimated Drilling and Completion Costs”). Seller shall be responsible for all costs invoiced pursuant to such AFEs up to the amount of the Estimated Drilling and Completion Costs (but excluding any costs set forth under the heading “Northern Capex”), regardless of whether such costs are incurred or paid prior to, on or after the Effective Time and all such cost shall be allocated to Seller under this Section 2.4; provided, however, that Seller’s responsibility hereunder shall only apply to costs

15

invoiced on or before the 24 month anniversary of the Closing Date; and provided further that, with respect to any Well identified on Schedule 2.4, in the event the actual costs incurred for the scope of work set forth in the AFE for such Well is less than the Estimated Drilling and Completion Costs for such Well, Seller shall only be responsible for such actual costs. All other costs related to such wells shall be allocated to Purchaser.

(iv) All allocations of Hydrocarbon production shall be based upon meter readings or gauging and strapping data. Seller shall provide to Purchaser, no later than ten (10) Business Days prior to Closing, all gauge sheets necessary to support any allocation of production, for purposes of establishing the adjustment to the Cash Consideration pursuant to Section 3.2 hereof that will be used to determine the Closing Payment.

(v) Seller shall be allocated and bear all Asset Taxes attributable to (A) any Tax period ending prior to the Effective Time and (B) the portion of any Straddle Period ending immediately prior to the Effective Time, and Purchaser shall be allocated and bear all Asset Taxes attributable to (x) any Tax period beginning at or after the Effective Time and (y) the portion of any Straddle Period beginning at the Effective Time.

(vi) For purposes of determining the allocations described in Section 2.4(b)(v), (A) Asset Taxes that are attributable to the severance or production of Hydrocarbons (other than such Asset Taxes described in clause (C), below) shall be allocated to the period in which the severance or production giving rise to such Asset Taxes occurred, (B) Asset Taxes that are based upon or related to income or receipts or imposed on a transactional basis (other than such Asset Taxes described in clause (A) or (C)), shall be allocated to the period in which the transaction giving rise to such Asset Taxes occurred, and (C) Asset Taxes that are ad valorem, property or other Asset Taxes imposed on a periodic basis pertaining to a Straddle Period shall be allocated between the portion of such Straddle Period ending immediately prior to the Effective Time and the portion of such Straddle Period beginning at the Effective Time by prorating each such Asset Tax based on the number of days in the applicable Straddle Period that occur before the date on which the Effective Time occurs, on the one hand, and the number of days in such Straddle Period that occur on or after the date on which the Effective Time occurs, on the other hand.

(vii) To the extent the actual amount of an Asset Tax is not known at the time an adjustment is to be made with respect to such Asset Tax pursuant to this Section 2.4(b), the parties shall utilize the most recent information available in estimating the amount of such Asset Tax for purposes of such adjustment. To the extent the actual amount of an Asset Tax (or the amount thereof paid or economically borne by a Party) is ultimately determined to be different than the amount (if any) that was taken into account in the final settlement of the Adjusted Cash Consideration, timely payments will be made from one party to the other to the extent necessary to cause each party to bear the amount of such Asset Tax that is allocable to such party under this Section 2.4(b).

16

Section 2.5 Delivery and Maintenance of Records. Seller shall deliver the Records to Purchaser within ten (10) days following Closing and, upon request of Purchaser, provide Purchaser with access thereto, during Seller’s normal business hours, from and after Closing prior to delivery. Purchaser shall be entitled to all original Records. Seller shall be entitled to keep copies of all Records; provided, however, that Seller shall not sell or otherwise allow third parties to review, copy or otherwise use any Records retained by Seller except as required by Law, or permitted in connection with a transfer pursuant to Section 13.8. Purchaser shall preserve the Records for a period of ten (10) years following the Closing and will allow Seller and its representatives, consultants and advisors reasonable access, during normal business hours and upon reasonable notice, to the Records for any legitimate business reason of Seller, including in order for Seller to comply with a Tax or other legally required reporting obligation or Tax or legal dispute. 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 ten (10) years following the Closing Date, Purchaser shall not and shall cause its Affiliates, its permitted transferees, designees and assigns hereunder 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 such records or such portions thereof.

ARTICLE 3

PURCHASE PRICE

Section 3.1 Purchase Price; Deposit.

(a) Initial Consideration. The purchase price for the Assets shall be (i) $100,000,000 in cash or other immediately available funds (the “Cash Consideration”), adjusted as provided in Section 3.2; and (ii) 56,371,899 shares of Purchaser Common Stock (the “Stock Consideration”; and together with the Cash Consideration and Additional Consideration, as adjusted, the “Purchase Price”).

(b) Deposit. A deposit equal to $20,000,000 (the “Deposit”; and together with any accrued interest thereon, the “Escrow Funds”) shall be paid by Purchaser within five (5) days after execution of this Agreement, by wire transfer in immediately available funds, to the Escrow Agent to be held in the Escrow Account. At Closing, the Escrow Funds shall be disbursed by the Escrow Agent to Seller and shall reduce the Adjusted Cash Consideration to be paid by Purchaser at Closing. Subject to the terms of Section 11.2, the Escrow Funds shall be non-refundable and, in the event the transaction contemplated hereby is not consummated in accordance with the terms hereof, the Escrow Funds shall be paid to Seller. If for any reason this Agreement is terminated in accordance with Section 11.1, then the Escrow Funds shall be disbursed or retained as provided in Section 11.2.

(c) Additional Consideration. If, for any Reference Month, the Reference Price for such calendar month exceeds the Test Price for such calendar month, then on or before the later of (A) the fifth (5th) Business Day after the end of such Reference Month or (B) the third (3^rd) Business Day after Purchaser’s receipt of the Monthly Activity Report for such Reference Month (each such date being a “Measurement Date”), Purchaser will pay to Seller an additional amount (the “Additional Consideration”) equal to: (i) the Reference Price for such Reference Month minus the Test Price for such Reference Month, multiplied by (ii) an amount

17

(which shall not be less than zero) equal to (y) the Unrestricted Shares for such Reference Month, less (z) any shares of Purchaser Common Stock disposed of by Seller during such Reference Month at a price exceeding the applicable Reference Price for such Reference Month. The Additional Consideration, if any, shall be paid by Purchaser to Seller in cash or other immediately available funds on each relevant Measurement Date; provided, however, that with respect to any Reference Month, Purchaser may, if permitted by Section 3.1(d) below, but shall not be obligated to, satisfy all or a portion of any Additional Consideration due by issuing to Seller that number of additional shares of Purchaser Common Stock equal to the Additional Consideration for such Reference Month, divided by the Test Price for such Reference Month, rounded to the nearest whole share.

(d) Limitation on Purchaser Common Stock. Notwithstanding the foregoing, under no circumstances shall Purchaser issue shares of Purchaser Common Stock as Stock Consideration or as Additional Consideration to the extent such issuance would result in the issuance under this Agreement of greater than 19.9% of the total number of shares of Purchaser Common Stock that are issued and outstanding as of the Closing Date (before giving effect to the issuances contemplated by this Agreement). To the extent any issuance of shares of Purchaser Common Stock as Additional Consideration required by this Agreement would result in the issuance under this Agreement of greater than 19.9% of the total number of shares of Purchaser Common Stock that are issued and outstanding as of the Closing Date (before giving effect to the issuances contemplated by this Agreement), Purchaser shall instead pay to Seller in cash or other immediately available funds the amount of such Additional Consideration.

Section 3.2 Adjustments to Cash Consideration. The Cash Consideration for the Assets shall be adjusted in the manner specified below (without duplication), with all such amounts being determined in accordance with GAAP and COPAS standards, as applicable, in order to reach the Adjusted Cash Consideration:

(a) Reduced by the aggregate amount of the following proceeds received by Seller between (and including) the Effective Time and the Closing Date (with the period between the Effective Time and the Closing Date referred to as the “Adjustment Period”): (i) proceeds from the sale of Hydrocarbons (net of any royalties, overriding royalties or other burdens on or payable out of production and gathering, processing and transportation costs) produced from or attributable to the Properties during the Adjustment Period, and (ii) other proceeds earned with respect to the Assets during the Adjustment Period;

(b) Increased by the aggregate amount of the following proceeds received by Purchaser: (i) proceeds from the sale of Hydrocarbons (net of any royalties, overriding royalties or other burdens on or payable out of production and gathering, processing and transportation costs) produced from or attributable to the Properties during the period prior to the Effective Time, and (ii) other proceeds earned with respect to the Assets attributable to the period prior to the Effective Time;

(c) Reduced to the extent provided in Section 8.6 with respect to Preference Rights and Retained Assets;

18

(d) (i) If the parties make the election under Section 4.4(d)(i) with respect to a Title Defect, subject to the Individual Title Defect Threshold and Defect Deductible, reduced by the Title Defect Amount with respect to such Title Defect if the Title Defect Amount has been determined prior to Closing and (ii) increased by the Title Benefit Amount with respect to each Title Benefit for which the Title Benefit Amount has been determined prior to Closing;

(e) Increased by the amount of all Property Costs and other costs attributable to the ownership and operation of the Assets which are incurred during the Adjustment Period and paid by Seller (irrespective of whether paid before or after the Effective Time), except, in each case (i) any Property Costs and other such costs already deducted in the determination of proceeds in Section 3.2(a), (ii) any amounts otherwise allocated in accordance with Section 2.4(b)(iii) and (iii) any Asset Taxes, Income Taxes and Transfer Taxes;

(f) Reduced to the extent provided in Section 4.4(d)(iii) for any Properties excluded from the Assets pursuant to Section 4.4(d)(iii) and reduced to the extent provided in Section 5.3 for Environmental Defects;

(g) Adjusted for Asset Taxes as follows:

(i) increased by the amount of all Asset Taxes allocated to Purchaser in accordance with Section 2.4(b)(v) but paid or otherwise economically borne by Seller; and

(ii) decreased by the amount of all Asset Taxes allocated to Seller in accordance with Section 2.4(b)(v) but paid or otherwise economically borne by Purchaser;

(h) Increased or reduced as mutually agreed upon in writing prior to Closing by Seller and Purchaser, including in accordance with Section 2.4(b)(iii);

(i) Increased by the amount of any Imbalances resulting from net underproduction by Seller;

(j) Reduced by the amount of any Imbalances resulting from net overproduction by Seller; and

(k) Each adjustment made pursuant to Section 3.2(a) shall serve to satisfy, up to the amount of the adjustment, Purchaser’s entitlement under Section 2.4 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 3.2(e) shall serve to satisfy, up to the amount of the adjustment, Purchaser’s obligation under Section 2.4 to pay Property Costs and other costs attributable to the ownership and operation of the Assets (excluding any Asset Taxes, Income Taxes and Transfer Taxes) which are incurred during the Adjustment Period.

19

Section 3.3 Allocation of Purchase Price. The Allocated Values assigned to the Wells and Development Locations are set forth in Schedule 3.3. Purchaser and Seller shall use commercially reasonable efforts to agree to an allocation of the Purchase Price and any other items properly treated as consideration for U.S. federal income tax purposes among the Assets in accordance with Section 1060 of the Code and the Treasury Regulations promulgated thereunder and, to the extent allowed under applicable federal income tax Law, in a manner consistent with the Allocated Values, within thirty (30) days after the Final Settlement Date (the “Allocation”). If Seller and Purchaser reach an agreement with respect to the Allocation, (a) Purchaser and Seller shall use commercially reasonable efforts to update the Allocation in accordance with Section 1060 of the Code following any adjustment to the Purchase Price pursuant to this Agreement, and (b) Purchaser and Seller shall, and shall cause their respective Affiliates to, report consistently with the Allocation, as adjusted, on all Tax Returns, including Internal Revenue Service Form 8594 (Asset Acquisition Statement under Section 1060), and none of Seller or Purchaser shall take any position on any Tax Return that is inconsistent with the Allocation, as adjusted, unless otherwise required by applicable Law; provided, however, that neither party shall be unreasonably impeded in its ability and discretion to negotiate, compromise and/or settle any Tax audit, claim or similar proceedings in connection with such allocation.

(a) Except for the special warranty of Defensible Title as contemplated by Section 4.1(b), 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 PURCHASER’S SOLE REMEDY FOR ANY DEFECT OF TITLE, INCLUDING ANY TITLE DEFECT, WITH RESPECT TO ANY OF THE ASSETS SHALL BE PURSUANT TO THE PROCEDURES SET FORTH IN THIS ARTICLE 4.

(b) The Conveyance shall contain a special warranty of Defensible Title to the Assets by Seller unto Purchaser against every Person whomsoever lawfully claiming by, through and under Seller, but not otherwise, subject, however, to the Permitted Encumbrances.

(c) Notwithstanding anything herein provided to the contrary, if a Title Defect under this Article 4 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 to the extent permitted by this Article 4, and shall be precluded from also asserting such matter as the basis of the breach of any representation or warranty.

20

Section 4.2 Definitions of Title Matters. As used in this Agreement, the term “Defensible Title” means that title of Seller with respect to the Wells and Development Locations set forth on Exhibit B-1 and Exhibit B-2, except for and subject to Permitted Encumbrances and the terms and provisions of the Contracts, the Surface Contracts and the Conveyance, that:

As used in this Agreement, the term “Title Defect” means any lien, charge, encumbrance, obligation (including contract obligation), defect (including those contemplated by clause (c) above), 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 Wells and Development Locations set forth on Exhibit B-1 and Exhibit B-2 as of the Effective Time and the Closing. Notwithstanding the foregoing, the following shall not be considered Title Defects provided that Seller’s revenues related to any Well are not currently being held in suspense related to any such matters:

21

(i) defects arising out of lack of corporate or similar entity authorization unless Purchaser provides affirmative written evidence that the action was not authorized and results in another Person’s superior claim of title;

(ii) defects based on failure to record Leases issued by any local, Indian, state or federal Governmental Body, or any assignments of such Leases, in the real property, conveyance or other records of the county in which such Property is located;

(iii) defects based on a gap in Seller’s chain of title in the federal, state or 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;

(iv) defects in the chain of title consisting of the failure to recite marital status in a document or omissions of successions of heirship or estate proceedings, unless Purchaser provides affirmative evidence that such failure or omission has resulted in another Person’s superior claim of title;

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

(vi) defects or depth severances that pertain to any formation or common source of supply other than the Formation applicable to the subject Well or Development Location;

(vii) immaterial defects or irregularities resulting from or related to probate proceedings, which defects or irregularities have been outstanding for ten (10) years or more;

(viii) defects arising from prior oil and gas leases relating to lands covered by any Leases that are not released of record and that have expired on the face of the terms of such instrument, unless Purchaser provides affirmative written evidence that such failure or omission results in another Person’s superior claim of title;

(ix) any maintenance of uniform interest provision under any joint operating agreement (including any past violations of such provisions);

(x) defects based on (A) lack of information, including lack of information in Seller’s files, the lack of third party records or the unavailability of information from any Governmental Body, or (B) references to a document(s) if such document(s) is not in Seller’s files;

(xi) defects arising out of lack of survey, unless a survey is expressly required by Law; and

22

(xii) such other defects or irregularities in the title to the Assets that would be accepted by a reasonably prudent purchaser engaged in the business of owning and operating oil and gas properties in the region where the Assets are located.

As used in this Agreement, the term “Title Benefit” means any right, circumstance or condition that operates to increase the Net Revenue Interest of Seller in any Well or Development Location set forth on Exhibit B-1 or Exhibit B-2 (limited to the applicable Formation of such Well or Development Location), without causing a greater than proportionate increase in Seller’s working interest above that shown in Exhibit B-1 or Exhibit B-2 as of the Effective Time.

Section 4.3 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, net profit interests, production payments, carried interests, and other burdens, to the extent that any such burden does not (i) reduce Seller’s Net Revenue Interest with respect to any Well or Development Location set forth in Exhibit B-1 or Exhibit B-2 below that shown in Exhibit B-1 or Exhibit B-2 or (ii) increase Seller’s working interest with respect to any Well or Development Location set forth in Exhibit B-1 or Exhibit B-2 above that shown in Exhibit B-1 or Exhibit B-2 without at least a proportionate increase in the Net Revenue Interest;

(b) All Leases, all Contracts listed in Schedule 2.2(d) and all Surface Contracts listed in Schedule 2.2(e), to the extent that they do not, individually or in the aggregate, (i) reduce Seller’s Net Revenue Interest with respect to any Well or Development Location set forth in Exhibit B-1 or Exhibit B-2 below that shown in Exhibit B-1 or Exhibit B-2 or (ii) increase Seller’s working interest with respect to any Well or Development Location set forth in Exhibit B-1 or Exhibit B-2 above that shown in Exhibit B-1 or Exhibit B-2 without at least a proportionate increase in the Net Revenue Interest;

25

SECTION 4.4(a) ON OR BEFORE THE TITLE CLAIM DATE. For purposes hereof, the “Allocated Value” of an Asset means the portion of the Total Allocated Value that has been allocated to a particular Well or Development Location in Schedule 3.3 as prepared by Purchaser and reviewed for reasonableness by Seller.

(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 Wells or Development Locations affected, (iii) the Allocated Values of the Well or Development Location set forth in Exhibit B-1 or Exhibit B-2 subject to such Title Benefit, and (iv) the amount by which Seller reasonably believes the Allocated Value of those Wells or Development Locations is increased by the Title Benefit, and the computations and information upon which Seller’s belief is based. NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT TO THE CONTRARY, SELLER SHALL BE DEEMED TO HAVE WAIVED ITS RIGHT TO ASSERT TITLE BENEFITS OF WHICH PURCHASER HAS NOT BEEN GIVEN NOTICE ON OR BEFORE THE TITLE CLAIM DATE.

(c) Seller shall have the right, but not the obligation, to attempt, at its sole cost and expense, to cure or remove Title Defects at any time prior to Closing (the “Cure Period”), unless the parties otherwise agree, any Title Defects of which Seller has been advised in writing by Purchaser. Any asserted Title Defects which are cured within the Cure Period or waived or deemed waived by Purchaser shall be deemed Permitted Encumbrances hereunder.

(d) In the event that any Title Defect is not waived by Purchaser or cured on or before Closing, Purchaser and Seller shall mutually agree to have one of the following remedies apply:

(i) subject to the Individual Title Defect Threshold and Defect Deductible, have the Cash Consideration reduced by an amount (“Title Defect Amount”) agreed upon pursuant to Section 4.4(g) by Purchaser and Seller as being the value of such Title Defect, taking into consideration the Allocated Value of the Property subject to such Title Defect, the portion of the Property subject to such Title Defect and the legal effect of such Title Defect on the Property affected thereby; provided, however, that the methodology, terms and conditions of Section 4.4(g) shall control any such determination;

(ii) Seller shall indemnify Purchaser against all liability, loss, cost and expense resulting from such Title Defect pursuant to an indemnity agreement mutually acceptable to the parties; or

(iii) Seller shall retain the entirety of the Property that is subject to such Title Defect, together with all associated Assets, in which event the Cash Consideration payable at Closing shall be reduced by an amount equal to the Allocated Value of such Property. Thereafter, Seller shall have 180 days after Closing in which to cure the Title Defect with respect to such retained Properties. Any Property so held back from the initial Closing will be conveyed to Purchaser at a delayed Closing (which shall become the new Closing Date with respect to such Property) within ten (10) days following the

26

date that the Title Defect is cured to Purchaser’s reasonable satisfaction, at which time Purchaser shall pay to Seller the full Allocated Value of the Property, and provided further that if multiple delayed Closings are contemplated as a result of this provision and/or Section 8.6(c), the delayed Closings may be consolidated on dates mutually agreeable to the parties. An election to delay the Closing pursuant to this Section 4.4(d)(iii) shall not waive Seller’s right to dispute the existence of a Title Defect or to contest the Title Defect Amount asserted with respect thereto. In the event that Seller is unable to cure the Title Defect within 180 days of the initial Closing, then Seller shall, at its sole election, select one of the two remedies set forth in subsection (i) or (ii) of this Section 4.4(d). Should Purchaser’s choice ultimately lead to application of Section 4.4(k), the Title Expert shall be selected within fifteen (15) Business Days of the end of this 180 day cure period. All other provisions of Section 4.4(k) shall apply as written.

In the event that Purchaser and Seller fail to agree upon one of the foregoing remedies with respect to a Title Defect asserted by Purchaser pursuant to Section 4.4(a) prior to Closing, then the remedy set forth in clause (iii) shall apply as the remedy for such Title Defect, and if the parties cannot agree on whether any Title Defect that has been asserted actually constitutes a Title Defect and as a result the parties cannot agree whether the conditions in Section 9.1(e) and Section 9.2(e) have been satisfied as of Closing, then the parties shall cause such dispute to be resolved prior to the Closing in accordance with Section 4.4(k) in order to determine whether such conditions have been satisfied. In the event the parties select the remedy set forth in clause (i) above, and Purchaser and Seller are unable to agree on the Title Defect Amount, the affected Assets will nevertheless be conveyed to Purchaser at Closing with a reduction in the Cash Consideration payable at Closing for such Title Defect based upon the Title Defect Amount asserted by Purchaser, subject to Seller’s right to a subsequent adjustment in the Cash Consideration for such Title Defect as may result under the provisions of Section 4.4(k), or as may otherwise be agreed to by the parties.

(e) With respect to each Well and Development Location set forth on Exhibit B-1 and Exhibit B-2 affected by Title Benefits reported under Section 4.4(b), the aggregate Title Benefit Amounts, but only for those individual Title Benefits that exceed the Individual Title Defect Threshold and then only in the event the aggregate of such Title Benefit Amounts exceeds the Title Defect Deductible (and only to the extent of such excess), may be used to offset the aggregate of all Title Defect Amounts, if any.

(f) Section 4.4(d) shall be the exclusive right and remedy of Purchaser with respect to Title Defects asserted by Purchaser pursuant to Section 4.4(a). Section 4.4(e) shall be the exclusive right and remedy of Seller with respect to Title Benefits asserted by Seller pursuant to Section 4.4(b).

(g) 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:

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

27

(ii) if the Title Defect is a lien, encumbrance or other charge which is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property;

(iii) if the Title Defect results from Seller having a lesser Net Revenue Interest in such Title Defect Property than the Net Revenue Interest specified therefor in Exhibit B-1 or Exhibit B-2 and the working interest attributable to such Title Defect Property has been proportionately reduced, the Title Defect Amount shall be equal to the product obtained by multiplying the Allocated Value of such Title Defect Property by a fraction, the numerator of which is the reduction in the Net Revenue Interest and the denominator of which is the Net Revenue Interest specified for such Title Defect Property in Exhibit B-1 or Exhibit B-2;

(iv) if the Title Defect results from any matter not described in subsections (i), (ii) or (iii) above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Asset so affected, the portion of Seller’s interest in the Asset affected by the Title Defect, the legal effect of the Title Defect, the potential present value economic effect of the Title Defect over the life of the affected Asset, the values placed upon the Title Defect by Purchaser and Seller, the estimated capital and operational costs and expenses (or reduction or increases thereof) attributable to Seller’s working interest, and such other factors as are necessary to make an evaluation and determination of such value; and

(v) notwithstanding anything to the contrary in this Article 4, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of the Title Defect Property.

(h) The Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder. For example, if a lien affects more than one Title Defect Property or the curative work with respect to one Title Defect results (or is reasonably expected to result) in the curing of any other Title Defect affecting the same or another Title Defect Property, the amount necessary to discharge such lien or the cost and expense of such curative work shall be allocated among the Title Defect Properties so affected (in the ratios of the Allocated Values of such Title Defect Properties) and the amount so allocated to a Title Defect Property shall be included only once in the Title Defect Amount and shall be aggregated for purposes of determining whether the Title Defect Amount exceeds the Individual Title Defect Threshold. For the avoidance of doubt, the parties acknowledge and agree that a defect with respect to any Well or Development Location shall take into account any defects related to the Leases related to such Well or Development Location.

(i) No Title Defect Amount shall be allowed on account of and to the extent that an increase in Seller’s working interest in a Property has the effect of proportionately increasing Seller’s Net Revenue Interest in such Property.

(j) The “Title Benefit Amount” for any Title Benefit means, with respect to an affected Well or Development Location, the amount by which the value of the affected Well

28

or Development Location is enhanced by virtue of (A) Seller having a greater Net Revenue Interest in such Well or Development Location than the Net Revenue Interest specified therefor in Exhibit B-1 or Exhibit B-2, (B) Seller having a lesser working interest in such Well or Development Location than the working interest specified therefor in Exhibit B-1 or Exhibit B-2, or (C) such Well or Development Location being subject to lesser lien indebtedness than expressly disclosed in any Exhibit or Schedule hereto, which amount shall be determined as follows:

(i) If Purchaser and Seller agree on the Title Benefit Amount, that agreed amount shall be the Title Benefit Amount.

(ii) If the Title Benefit results from the affected Well or Development Location being subject to lesser lien indebtedness, the Title Benefit Amount shall be equal to the amount of the reduction in such lien indebtedness; provided that, if lien indebtedness affects more than one Well or Development Location, the Title Benefit Amount with respect to such affected Well or Development Location shall be determined in the manner provided in Section 4.4(h).

(iii) If the Title Benefit Amount results from Seller having a greater Net Revenue Interest (without a corresponding increase in working interest) in such Well or Development Location than the Net Revenue Interest specified therefor in Exhibit B-1 or Exhibit B-2, the Title Benefit Amount shall be equal to the product obtained by multiplying the Allocated Value of such Well or Development Location by a fraction, the numerator of which is the increase in the Net Revenue Interest, and the denominator of which is the Net Revenue Interest specified for such Well or Development Location in Exhibit B-1 or Exhibit B-2.

(iv) In determining the amount of Title Benefit Amounts, the principles and methodology set forth in Section 4.4(g) shall generally be applied, mutatis mutandis.

(k) Seller and Purchaser shall attempt in good faith to agree on (x) all Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts, and (y) the adequacy of any curative materials provided by Seller to cure an alleged Title Defect (with any failure to agree on items (x) and (y) becoming, collectively, the “Disputed Title Matters”) prior to Closing or the end of the 180 day cure period, as applicable. If Seller and Purchaser are unable to agree by Closing or the end of the 180 day cure period, as applicable, the Disputed Title Matters shall be exclusively and finally resolved pursuant to this Section 4.4(k). There shall be a single arbitrator, who shall be 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 and shall not have performed professional services for either party or any of their respective Affiliates during the previous three (3) years, as selected by mutual agreement of Purchaser and Seller within fifteen (15) Business Days after the end of the Cure Period or the end of the 180 day cure period, as applicable (the “Title Expert”). The Title Expert’s determination shall be made within fifteen (15) Business Days after submission of the matters in dispute and shall be final and binding upon all parties, without right of appeal. In making his determination, the Title Expert shall be bound by the rules set forth in Section 4.4(g), Section 4.4(h), Section 4.4(i) and Section 4.4(j) and may consider such other matters as in the opinion of the Title Expert are necessary or helpful to make

29

a proper determination. The Title Expert may allow the parties to make written submissions of their positions in the manner and to the extent the Title Expert deems appropriate, and the Title Expert may call on the parties to submit such other materials as the Title Expert deems helpful and appropriate to resolution of the dispute. Additionally, the Title Expert may consult with and engage disinterested third parties to advise the arbitrator, including without limitation petroleum engineers and other experts as necessary. The Title Expert, however, may not award (A) Purchaser a greater Title Defect Amount than the Title Defect Amount claimed by Purchaser in its applicable Title Defect Notice or (B) Seller a greater Title Benefit Amount than the Title Benefit Amount claimed by Seller in the applicable Title Benefit Notice. The Title Expert shall act as an expert for the limited purpose of determining the specific Disputed Title Matters submitted by either party and may not award damages, interest or penalties to any party with respect to any matter. Seller and Purchaser shall each bear their own legal fees and other costs of presenting its case. The costs and expenses of the Title Expert shall be borne and paid one-half by Seller and one-half by Purchaser, including any costs incurred by the Title Expert that are attributable to such third party consultation. Within ten (10) days after the Title Expert delivers written notice to Purchaser and Seller of his award with respect to a Disputed Title Matter, (i) Purchaser shall pay to Seller the amount, if any, so awarded by the Title Expert to Seller, (ii) Seller shall pay to Purchaser the amount, if any, so awarded by the Title Expert to Purchaser and (iii) if the affected Title Defect Property was retained by Seller at Closing, Seller shall assign to Purchaser such affected Title Defect Property pursuant to an instrument in substantially the same form as the Conveyance.

(l) Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Cash Consideration or other remedies provided by Seller for any uncured Title Defects for which the Title Defect Amount does not exceed $25,000 (the “Individual Title Defect Threshold”); and (ii) in no event shall there be any adjustment to the Cash Consideration or other remedies provided by Seller for any Title Defect for which the Title Defect Amount exceeds the Individual Title Defect Threshold unless (A) the amount of the sum of (1) the aggregate Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold (but excluding any Title Defect Amounts attributable to Title Defects cured by Seller), plus (2) the aggregate Environmental Defect Amounts of all Environmental Defects that exceed the Individual Environmental Threshold (but excluding any Environmental Defects cured by Seller), exceeds (B) an amount equal to two percent (2%) of the Total Allocated Value (the “Defect Deductible”), after which point adjustments to the Cash Consideration or other remedies shall be made or available to Purchaser, but only to the extent that the amount by which the aggregate amount of such Title Defect Amounts and Environmental Defect Amounts exceeds the Defect Deductible.

Section 4.5 Casualty or Condemnation Loss.

(a) Notwithstanding anything herein to the contrary, from and after the Effective Time, if Closing occurs, Purchaser shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any well, collapsed casing or sand infiltration of any well) and the depreciation of Equipment due to ordinary wear and tear, in each case, with respect to the Assets, and Purchaser shall not assert such matters as Casualty Losses or Title Defects hereunder.

30

(b) If, after the date of this Agreement but prior to Closing Date, any portion of the Assets is destroyed by fire or other casualty or is expropriated or taken in condemnation or under right of eminent domain (a “Casualty Loss”), subject to Purchaser’s right under this Section 4.5(b) and Purchaser’s termination right under Section 11.1(d), this Agreement shall remain in full force and effect, and Purchaser shall nevertheless be required to close the transactions contemplated hereby. In the event that the amount of the costs and expenses associated with repairing or restoring the Assets affected by such Casualty Loss exceeds Five Hundred Thousand Dollars ($500,000) net to Seller’s interest, Seller must elect by written notice to Purchaser prior to Closing either to (i) cause the Assets affected by such Casualty Loss to be repaired or restored, at Seller’s sole cost, as promptly as reasonably practicable (which work may extend after the Closing Date), or (ii) indemnify Purchaser under an indemnification agreement mutually acceptable to the parties against any costs or expenses that Purchaser reasonably incurs to repair or restore the Assets subject to such Casualty Loss. In each case, Seller shall retain all rights to insurance and other claims against third parties with respect to the applicable Casualty Loss except to the extent the parties otherwise agree in writing. Seller shall have no other liability or responsibility to Purchaser with respect to a condemnation or Casualty Loss, EVEN IF SUCH CASUALTY LOSS SHALL HAVE RESULTED FROM OR SHALL HAVE ARISEN OUT OF THE SOLE OR CONCURRENT NEGLIGENCE, FAULT OR VIOLATION OF A LEGAL REQUIREMENT OF SELLER.

Section 4.6 Limitations on Applicability. The right of Purchaser to assert a Title Defect under this Agreement and Seller’s right to assert a Title Benefit under this Agreement shall terminate as of the Title Claim Date, provided there shall be no termination of Purchaser’s or Seller’s rights under Section 4.4 with respect to any bona fide Title Defect properly reported in a Title Defect Notice or bona fide Title Benefit properly reported in a Title Benefit Notice on or before the Title Claim Date.

Section 4.7 Government Approvals Respecting Assets.

(a) Federal and State Approvals. Purchaser shall, within thirty (30) days after Closing and at Purchaser’s own expense, file for approval with the applicable Governmental Bodies all assignment documents and other state, federal and Indian transfer documents required to effectuate the transfer of the Assets. Purchaser further agrees, promptly after Closing, to take all other actions reasonably required of Purchaser by federal, state or Indian agencies having jurisdiction to obtain all requisite regulatory approvals with respect to this transaction, and to use its commercially reasonable efforts to obtain the approval by such federal, state or Indian agencies, as applicable, of Seller’s assignment documents requiring federal, state or Indian approval in order for Purchaser to be recognized by the federal, state or Indian agencies as the owner of the Assets. Purchaser shall provide Seller with approved copies of the assignment documents and other state, federal and Indian transfer documents, as soon as they are available.

(b) Title Pending Governmental Approvals. Until all of the governmental approvals provided for in Section 4.7(a) have been obtained, the following shall occur with respect to the affected portion of the Assets:

(i) Seller shall continue to hold record title to the affected Leases and other affected portion of the Assets as nominee for Purchaser;

31

(ii) Purchaser shall be responsible for, and shall indemnify and hold harmless Seller from, all Assumed Seller Obligations with respect to the affected Leases and other affected portion of the Assets as if Purchaser was the record owner of such Leases and other portion of the Assets as of the Effective Time;

(iii) Seller shall act as Purchaser’s nominee but shall be authorized to act only upon and in accordance with Purchaser’s instructions, and Seller shall have no authority, responsibility or discretion to perform any tasks or functions with respect to the affected Leases and other affected portion of the Assets other than those which are purely administrative or ministerial in nature, unless otherwise specifically requested and authorized by Purchaser in writing;

(iv) Seller shall not be obligated to incur any expenses in Seller’s capacity as nominee for the benefit of Purchaser under this Section 4.7(b), and Purchaser agrees to pay or reimburse Seller for any such expenses promptly upon receiving notice thereof; and

(v) For purposes of Article 12, Seller and Purchaser shall treat and deal with such affected Leases and other affected portions of the Assets as if full legal and equitable title to the same had passed from Seller to Purchaser at Closing.

ARTICLE 5

ENVIRONMENTAL MATTERS

Section 5.1 Assessment. From and after the date of execution of this Agreement until the Closing Date, Seller shall afford to Purchaser and its officers, employees, agents and authorized representatives reasonable access to the Assets, including the Records in accordance with Section 8.1. Upon reasonable notice to Seller, Purchaser shall be entitled to conduct a Phase I environmental property assessment of the Assets that satisfies the basic assessment requirements set forth under the current American Society for Testing and Material Standard Practice for Phase I environmental property assessments (Designation E1527-05) (the “Phase I Assessment” or “Phase I”, whether one or more). The Phase I Assessment and Purchaser’s other diligence activities shall be conducted at the sole cost, risk and expense of Purchaser, and shall be subject to the indemnity provisions of Section 5.4. Seller or its designee shall have the right to accompany Purchaser and Purchaser’s representatives whenever they are onsite on Assets and also to collect split test samples if any are collected. Notwithstanding anything herein to the contrary, Purchaser shall not have access to, and shall not be permitted to conduct any environmental due diligence (including all or any part of the Phase I Assessments or the Phase II Assessments) with respect to, any Assets with respect to which Seller or its Affiliates do not have the authority to grant access for such due diligence; provided, however, Seller and its Affiliates shall use their commercially reasonable efforts to obtain permission from any other Person to allow Purchaser and Purchaser’s representatives such access and as long as Seller and its Affiliates have exercised such commercially reasonable efforts, Seller shall have no liability to Purchaser for failure to obtain any such other Person’s permission. In the event that Purchaser’s Phase I Assessment identifies in good faith actual or potential “Recognized Environmental Conditions,” as such conditions are defined or described under the current ASTM International Standard Practice Designation E1527-13, then Purchaser may request Seller’s

32

consent to conduct additional Phase II environmental property assessments, including the collection and analysis of environmental samples (collectively, the “Phase II Assessment” or “Phase II,” whether one or more). The Phase II Assessment procedures and plan concerning any additional investigation shall be submitted to Seller in a written environmental property assessment plan, and shall be reasonable based on the recognized environmental concerns identified by the Phase I Assessment. Thereafter, Seller may, in its sole discretion, approve or deny said environmental property assessment plan, in whole or in part, and Purchaser shall not have the right to conduct any activities set forth in such plan unless and until such time that Seller has approved such plan in writing; provided, that notwithstanding Seller’s rejection of said environmental property assessment plan, in whole or in part, Purchaser may still deliver an Environmental Defect Notice with respect to such Assets pursuant to Section 5.3. Any such approved environmental property assessment plan shall be performed in accordance with this Article 5 and in compliance with all Laws. Purchaser and Seller shall maintain, and shall cause their respective officers, employees, representatives, consultants and advisors to maintain, all information obtained by Purchaser pursuant to any Phase I, Phase II or other due diligence activity as strictly confidential until the Closing occurs, unless disclosure of any facts discovered through such Phase I, Phase II or other due diligence activity is required under any Laws. Purchaser shall provide Seller with a copy of the final version of all environmental reports prepared by, or on behalf of, Purchaser with respect to any Phase I, Phase II or other due diligence activity conducted on the Properties. In the event that any necessary disclosures under applicable Laws are required with respect to matters discovered by any Phase I, Phase II or other due diligence activity conducted by, for or on behalf of Purchaser, Purchaser agrees that Seller shall be the responsible party for disclosing such matters to the appropriate Governmental Bodies; provided that, if Seller fails to promptly make such disclosure and Purchaser or any of its Affiliates is legally obligated to make such disclosure, such Person shall have the right to fully comply with such legal obligation.

Section 5.2 NORM, Wastes and Other Substances. Purchaser acknowledges that the Assets have been used for the exploration, development, and production of Hydrocarbons and that there may be petroleum, produced water, wastes, or other substances or materials located in, on or under the Properties or associated with the Assets. Equipment and sites included in the Assets may contain Hazardous Materials, including NORM. NORM may affix or attach itself to the inside of wells, materials, and equipment as scale, or in other forms. The wells, materials, and equipment located on, in or under the Properties or included in the Assets may contain Hazardous Materials, including NORM. Hazardous Materials, including NORM, may have come in contact with various environmental media, including without limitation, water, soils or sediment. Special procedures may be required for the assessment, remediation, removal, transportation, or disposal of environmental media and Hazardous Materials, including NORM, from the Assets.

Section 5.3 Environmental Defects.

(a) If, as a result of its investigation pursuant to Section 5.1, Purchaser determines that with respect to the Assets, there exists a violation of an Environmental Law (other than with respect to NORM) (in each case, an “Environmental Defect”), then on or prior to 53 days after the date of this Agreement at 5:00 p.m. Central Time (the “Environmental Claim Date”), Purchaser may notify Seller in writing of such Environmental Defect (an “Environmental

33

Defect Notice”). 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 MEETING THE REQUIREMENTS OF THIS SECTION 5.3 RECEIVED BY SELLER ON OR BEFORE THE ENVIRONMENTAL CLAIM DATE. To be effective, each such notice must set forth (i) a description of the matter constituting the alleged Environmental Defect, (ii) the Leases, Units, Wells and associated Assets affected by the Environmental Defect, (iii) the estimated Lowest Cost Response to eliminate the Environmental Defect in question (the “Environmental Defect Amount”) and the calculation thereof, and (iv) supporting documents reasonably necessary for Seller to verify the existence of the alleged Environmental Defect and the Environmental Defect Amount.

(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 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. If (x) Seller disagrees with any of Purchaser’s assertions with respect to the existence of an Environmental Defect or the Environmental Defect Amount or (y) the adequacy of any cure by Seller of any asserted Environmental Defect is in dispute (with any failure to agree on items (x) and (y) becoming, collectively, the “Disputed Environmental Matters”), Purchaser and Seller will attempt to resolve the dispute prior to Closing (or after Closing if Seller attempts to cure an asserted Environmental Defect after Closing pursuant to this Section 5.3(b)). If the dispute cannot be resolved within ten (10) days of the first meeting of Purchaser and Seller, any party may submit the dispute to an environmental consultant 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 three (3) years (the “Independent Expert”). If the parties cannot agree on whether any Environmental Defect that has been asserted actually constitutes an Environmental Defect and as a result the parties cannot agree whether the conditions in in Section 9.1(e) and Section 9.2(e) have been satisfied as of Closing, then the parties shall cause such dispute to be resolved prior to the Closing in accordance with this Section 5.3(b) in order to determine whether such conditions have been satisfied. The Independent Expert may elect to 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 fifteen (15) Business Days of receiving such offers by selecting one or the other of the offers, or by crafting a decision that represents a compromise between the two offers; provided, however, that the Independent Expert may not award Purchaser any greater Environmental Defect Amount than the Environmental Defect Amount claimed by Purchaser in its applicable Environmental Defect Notice. In the event the parties have failed to resolve any Disputed Environmental Matter at Closing, Seller shall retain the Asset affected by the Environmental Defect, in which event the Cash Consideration payable at Closing shall be reduced by an amount equal to the Allocated Value of such Asset. Thereafter, the Independent Expert shall render his or her decision regarding the Environmental Defect and the Cash Consideration for such retained Asset subject to such Environmental Defect shall be reduced as determined by the Independent Expert or as

34

otherwise agreed to by the parties. Any Asset so held back from the initial Closing will be conveyed to Purchaser at a delayed Closing (which shall become the new Closing Date with respect to such Asset) within ten (10) days following the date that the Independent Expert delivers written notice to Purchaser and Seller of his or her award with respect to the Environmental Defect Amount, at which time Purchaser shall pay to Seller the full Allocated Value of the Asset less such Environmental Defect Amount.

(c) 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 all parties, without right of appeal. Seller and Purchaser shall each bear their own legal fees and other costs of presenting its case to the Independent Expert. The costs and expenses of the Independent Expert shall be borne and paid one-half by Seller and one-half by Purchaser. The parties shall adjust the Cash Consideration to reflect the Environmental Defect Amounts, as agreed by the parties or as determined by the Independent Expert, for all uncured Environmental Defects; provided, that notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Cash Consideration for any individual uncured Environmental Defect to the extent the Environmental Defect Amount, when combined with any Title Defect Amount for the affected Property, exceeds the Allocated Value of the affected Property; and (ii)(x) in no event shall there be any adjustments to the Cash Consideration or other remedies provided by Seller for any uncured Environmental Defects for which the Environmental Defect Amount does not exceed $100,000 (the “Individual Environmental Threshold”); and (y) in no event shall there be any adjustment to the Cash Consideration or other remedies provided by Seller for any Environmental Defect for which the Environmental Defect Amount exceeds the Individual Environmental Threshold unless (A) the amount of the sum of (1) the aggregate Environmental Defect Amounts of all such Environmental Defects that exceed the Individual Environmental Threshold (but excluding any Environmental Defects cured by Seller), plus (2) the aggregate Title Defect Amounts of all Title Defects that exceed the Individual Title Defect Threshold (but excluding any Title Defect Amounts attributable to Title Defects cured by Seller), exceeds (B) the Defect Deductible, after which point adjustments to the Cash Consideration or other remedies shall be made or available to Purchaser, but only to the extent that the amount by which the aggregate amount of such Title Defect Amounts and Environmental Defect Amounts exceeds the 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, Purchaser shall pay to Seller the Allocated Value for the Asset to which the Environmental Defect relates less the amount, if any, so awarded by the Independent Expert at the delayed Closing described above.

(d) Notwithstanding any other provision of this Section 5.3, in the event that the Environmental Defect Amount exceeds the Allocated Value of the affected Property, such Property, at the option of Purchaser, shall be permanently held back from the initial Closing and all delayed Closings, shall be considered an Excluded Asset, and the Cash Consideration shall be reduced by an amount equal to the Allocated Value of such affected Property.

35

Section 5.4 Inspection Indemnity. PURCHASER HEREBY AGREES TO DEFEND, INDEMNIFY, RELEASE, PROTECT, SAVE AND HOLD HARMLESS THE SELLER INDEMNIFIED PERSONS FROM AND AGAINST ANY AND ALL LOSSES ARISING OUT OF, OR RELATING TO, ANY DUE DILIGENCE ACTIVITY CONDUCTED BY PURCHASER OR ITS AGENTS, WHETHER BEFORE OR AFTER THE EXECUTION OF THIS AGREEMENT, EVEN IF SUCH LOSSES ARISE OUT OF OR RESULT FROM, IN WHOLE OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF, OR THE VIOLATION OF LAW BY, ANY SELLER INDEMNIFIED PERSON, EXCEPTING ONLY LOSSES TO THE EXTENT ACTUALLY RESULTING FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY SELLER INDEMNIFIED PERSON. The indemnity obligation set forth in this Section 5.4 shall survive the Closing or termination of this Agreement for a period of one (1) year.

Section 5.5 Confidentiality. Purchaser acknowledges that, pursuant to its right of access to the Records or the Assets, Purchaser and/or Purchaser’s representatives may become privy to confidential and other information of Seller or its Affiliates, and Purchaser shall ensure that such confidential information (i) shall not be used for any purpose other than in connection with the transactions contemplated hereby and (ii) shall be held confidential by Purchaser and Purchaser’s representatives in accordance with the terms of the Confidentiality Agreement. Purchaser agrees to inform Purchaser’s representatives of the confidential nature of such confidential information and to be responsible for any breach of this Section 5.5 by any of Purchaser’s representatives. If Closing should occur, the foregoing confidentiality restriction on Purchaser, including the Confidentiality Agreement, shall terminate as of the Closing Date (except as to (a) such portion of the Assets that are not conveyed to Purchaser pursuant to the provisions of this Agreement, (b) the Excluded Assets and (c) information related to Seller or its Affiliates or to assets other than the Assets).

Seller’s approval of any action restricted by this Section 8.5(b) shall be considered granted within ten (10) days of (unless a shorter time is reasonably required by the circumstances and such shorter time is specified in Purchaser’s written notice) Seller’s receipt of Purchaser’s written notice to Seller requesting such consent unless Seller notifies Purchaser to the contrary in writing during that period. In the event of an emergency, Purchaser may take such action as a prudent operator would take and shall notify Seller of such action promptly thereafter.

Section 8.6 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 6.12 with respect to the transactions contemplated by this Agreement. Seller shall use commercially reasonable efforts to obtain all applicable consents and to obtain waivers of applicable Preference Rights; provided, however, 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 written notice of such election prior to the Closing, such Preference Property will be eliminated from the Assets and the Cash Consideration shall be reduced by the Allocated Value of the Preference Property.

(c) If any of the following occurs:

(i) a third party brings any suit, action or other proceeding prior to the Closing seeking to restrain, enjoin or otherwise prohibit the consummation of the transactions contemplated hereby in connection with a claim to enforce a Preference Right;

48

(ii) an Asset is subject to a Transfer Requirement that provides that transfer of such Asset without compliance with such Transfer Requirement will result in termination or other material impairment of any rights in relation to such Asset, and such Transfer Requirement is not waived, complied with or otherwise satisfied prior to the Closing Date; or

(iii) the holder of a Preference Right does not elect to purchase such Preference Property or waive such Preference Right with respect to the transactions contemplated by this Agreement prior to the Closing Date and the time in which the Preference Right may be exercised has not expired;

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 Cash Consideration to be paid at Closing shall be reduced by the Allocated Value of such Retained Asset pursuant to Section 8.6(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 complies with or 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 8.6(c) (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 Cash Consideration was reduced on account of the holding back of such Retained Asset (as adjusted pursuant to Section 3.2 through the new Closing Date therefor); provided, however, if any 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 within one hundred eighty (180) days after the initial Closing has occurred with respect to any Asset, then such Retained Asset shall be eliminated from the Assets and shall become an Excluded Asset, unless Purchaser agrees to proceed with a closing on such Retained Asset, in which case Purchaser shall be deemed to have waived any objection (and shall be obligated to indemnify Seller Indemnified Person for all Losses) with respect to non-compliance with such Preference Rights and Transfer Requirements with respect to such Retained Asset(s).

Section 8.7 Tax Matters.

(a) Subject to the provisions of Section 13.3, Seller shall be responsible for all Taxes related to the Assets (other than Asset Taxes, which are addressed in Section 2.4) attributable to any period of time prior to the Effective Time, and Purchaser shall be responsible for all such Taxes related to the Assets attributable to any period of time on and after the Effective Time. Notwithstanding the foregoing, Seller shall handle payment to the appropriate

49

Governmental Body of all Asset Taxes which are required to be paid prior to Closing (and shall file all Tax Returns with respect to such Taxes required to be filed prior to Closing). If requested by Purchaser, Seller will assist Purchaser with preparation of all ad valorem and property Tax Returns required to be filed after Closing for periods ending on or before the Closing Date (including any extensions requested). Seller shall deliver to Purchaser within fifteen (15) days prior to the due date thereof copies of all Tax Returns to be filed by Seller prior to the Closing relating to Asset Taxes and any supporting documentation to be provided by Seller to Governmental Bodies for Purchaser’s approval, which shall not be unreasonably withheld, excluding Tax Returns related to Income Taxes. Purchaser shall file all Tax Returns covering Asset Taxes that are required to be filed after the Closing Date unless covered above. With respect to such Tax Returns covering a Straddle Period, Purchaser shall provide a copy of such Tax Return to Seller within fifteen (15) days prior to filing for Seller’s approval, which shall not be unreasonably withheld.

(b) Purchaser and Seller shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of any Tax Returns and any audit, litigation or other Proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information which are reasonably relevant to any such audit, litigation or other Proceeding and making employees reasonably available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Purchaser and Seller agree (i) to retain all books and records with respect to Tax matters pertinent to the Assets relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Purchaser or Seller, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any Governmental Body, and (ii) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, each party shall allow the other party the option of taking possession of such books and records prior to their disposal. Purchaser and Seller further agree, upon request, to use their commercially reasonable efforts to obtain any certificate or other document from any Governmental Body or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed with respect to the transactions contemplated hereby.

Section 8.8 Further Assurances. Before and after Closing, Seller shall promptly cooperate with Purchaser and Purchaser’s counsel and accountants in requesting and obtaining any required opinions, consents and letters from Seller’s independent auditors and reserve engineers in connection with SEC filings to be made by Purchaser and any registration statement to be filed pursuant to the Registration Rights Agreement. After the Closing, Seller and Purchaser shall, and shall cause their Affiliates, as applicable to, execute, acknowledge and deliver all such further conveyances, transfer orders, division orders, notices assumptions, releases and acquittances, and such other instruments, and shall take such further actions as may be necessary or appropriate to assure fully to Purchaser or Seller (including their successors and assigns) as the case may be, that the transactions described in this Agreement shall be completed and that all of the Assets intended to be conveyed under the terms of this Agreement are so conveyed, including such Assets that are improperly described herein or inadvertently omitted from this Agreement and/or the Conveyance (including the Exhibits attached to each) and to assure fully that Purchaser has assumed the liabilities and obligations intended to be assumed by Purchaser pursuant to this Agreement.

50

Section 8.9 Exclusivity.

(a) Until the earlier to occur of the Closing Date and the termination of this Agreement in accordance with its terms, Seller shall not, and shall cause its Affiliates and each of its and their respective representatives, agents, consultants and advisors not to, directly or indirectly, (i) encourage, solicit, facilitate, have or enter into any discussions, negotiations or agreements or other instruments (whether or not binding) regarding the sale of any of the Assets with, (ii) furnish or provide any information, diligence materials or diligence follow-up responses for the purposes of evaluating a transaction relating to the Assets to, any Person (other than Purchaser and its representatives, consultants and advisors) or (iii) grant new or allow continued access to any online or physical data room or diligence materials to any Person (other than Purchaser and its representatives, consultants and advisors). Seller shall, and shall cause its Affiliates and each of its and their respective representatives, consultants and advisors to, immediately cease and cause to be terminated all existing discussions or negotiations with any Persons (other than Purchaser and its representatives, consultants and advisors) with respect to, or that could lead to, the sale of any of the Assets. Seller represents and warrants that it has closed access to any data rooms (whether online or otherwise) to all Persons (other than Purchaser and its representatives, consultants and advisors).

(b) In the event that Seller receives an offer or expression of interest from any Person (other than Purchaser and its representatives, consultants and advisors) regarding the sale of any of the Assets, Seller shall inform such interested party that it has entered into exclusivity arrangements with another party that would be violated if Seller, directly or indirectly, engages in discussions with, or provides information to, such interested party.

(c) Seller acknowledges and agrees that the rights and remedies for noncompliance with this Section 8.9 shall include having such provision specifically enforced by any court having equity jurisdiction, it being acknowledged and agreed that any such breach or threatened breach shall cause irreparable injury to Purchaser and that money damages would not provide an adequate remedy to Purchaser.

Section 8.10 Legend. The certificates (or electronic equivalent) representing the Stock Consideration will initially bear a legend in substantially the following form:

THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. THE SECURITIES MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT (1) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OR (2) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH CASE IN ACCORDANCE WITH ALL APPLICABLE STATE SECURITIES LAWS AND THE SECURITIES LAWS OF OTHER JURISDICTIONS, AND IN THE

51

CASE OF A TRANSACTION EXEMPT FROM REGISTRATION, UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO IT THAT SUCH TRANSACTION DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT AND SUCH OTHER APPLICABLE LAWS.    

Section 8.11 Lockup; Standstill.

(a) General Lock-Up. Except as otherwise provided herein, Seller agrees that, during the Lock-Up Period, Seller will not directly or indirectly (i) offer, pledge, sell, contract to sell, grant any option or contract to purchase, purchase any option or contract to sell, or otherwise dispose of, directly or indirectly, any shares of Purchaser Common Stock or any securities convertible into, exercisable for or exchangeable for shares of Purchaser Common Stock, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Purchaser Common Stock, whether or not any such transaction is to be settled by delivery of Purchaser Common Stock, other securities, in cash or otherwise (collectively, the “Lock-Up Restrictions”). Seller also agrees and consents to the entry of stop transfer instructions with Purchaser’s transfer agent and registrar relating to the transfer of shares of Purchaser Common Stock held by Seller to ensure compliance with the restrictions described above. Notwithstanding anything herein to the contrary, the Lock-Up Restrictions will not apply to (i) entry into a customary voting or support agreement (with or without granting a proxy) in connection with a Business Combination or (ii) any transfer resulting from the consummation of a Business Combination.

(b) Lock-Up Release(s). The Lock-Up Restrictions shall initially apply to all of the Stock Consideration. On the first Business Day of each Reference Month, the Lock-Up Restrictions will cease to apply to the Unrestricted Shares for such Reference Month, and shall not thereafter apply to such Unrestricted Shares. The Lock-Up Restrictions shall not apply to any shares of Purchaser Common Stock issued as Additional Consideration; provided, however, that the Lock-Up Restrictions shall apply to any shares of Purchaser Common Stock issued as Additional Consideration and to the Stock Consideration (notwithstanding any earlier lapse of the Lock-Up Restrictions for any prior Reference Month) during the month of December 2018. After December 31, 2018, the Lock-Up Restrictions shall again cease to apply to all Unrestricted Shares for Reference Months prior to the month of December 2018.

(c) Volume Limitation. In addition to the Lock-Up Restrictions, during the Lock-Up Period Seller agrees not to dispose of shares of Purchaser Common Stock on any single trading day representing greater than 10% of the trailing 20-day average daily trading volume of Purchaser Common Stock (the “Volume Limitation”). Notwithstanding the foregoing, if the closing price of Purchaser Common Stock as reported by the NYSE American exceeds the applicable Reference Price for such calendar month for five consecutive trading days, then any shares sold on the next trading day after such five-day period at or above the Reference Price applicable to such month shall not count against the Volume Limitation.

(d) Standstill. From and after the date of execution of this Agreement until the earlier of (1) the date it is no longer possible for Additional Consideration to be paid under Section 3.1(c) and (2) the date that the Lock-Up Restrictions permanently cease to apply to Seller

52

(the “Standstill Period”), neither Seller nor any of its Affiliates or Representatives, will directly or indirectly (i) acquire, offer to acquire, or agree to acquire (whether beneficially, constructively or synthetically through any derivative, hedging or trading position or otherwise) any Purchaser Common Stock or other securities in any way related to the acquisition or price of securities or interests of Purchaser or any assets or indebtedness of Purchaser; provided, however, that during the Standstill Period Seller shall be permitted to acquire shares of Purchaser Common Stock so long as Seller’s ownership interest in Purchaser does not exceed 4.9% of the issued and outstanding Purchaser Common Stock; (ii) make, or in any way participate in, directly or indirectly, any “solicitation” of “proxies” (as such terms are used in the rules of the SEC promulgated under Section 14 of the Exchange Act) to vote, or seek to advise or influence any person or entity with respect to the voting of, any voting securities of Purchaser, (iii) make any public announcement with respect to, or submit a proposal for, or offer of (with or without conditions) any merger, consolidation, business combination, tender or exchange offer, restructuring, recapitalization or other extraordinary transaction of or involving Purchaser or its securities or assets, (iv) form, join or in any way participate in a “group” (as defined in Section 13(d)(3) of the Exchange Act) in connection with any voting securities of Purchaser, (v) otherwise act, alone or in concert with others, to seek to control, or influence control of, the management, board of directors or policies of Purchaser, (vi) make a request for any shareholder list or other books and records of Purchaser, (vii) make or cause to be made any public statement that disparages, defames or slanders Purchaser or any of its current or former directors, officers or employees (excluding any such statements made in connection with any bona fide commercial dispute between and among Purchaser, on the one hand, and Seller, on the other hand, and except as set forth in clause (x) below), (viii) take any action that would reasonably be expected to cause or require Purchaser to make a public announcement regarding any actions prohibited by this paragraph, (ix) contest the validity or enforceability of this Section 8.11(d), or (x) have any discussions or enter into any arrangements, understandings or agreements (whether written or oral) with, or advise or knowingly assist or encourage, any other persons in connection with any of the foregoing.

Section 8.12 Disclosure Schedules. From time to time up to the earlier of the Closing Date or termination of this Agreement pursuant to Article 11, Seller shall have the right to supplement or amend the schedules attached hereto that it has delivered with respect to any matter first existing or occurring following the date hereof that if existing or occurring at or prior to the date hereof, would have been required to be set forth or described in the schedules. Any such supplement or amendment to the schedules pursuant to the preceding sentence shall have the effect of modifying the representations and warranties contained in Article 6 for the purposes of determining whether a breach of the representation or, warranties for purposes of Article 12 has occurred, but shall not be given effect for the purposes of determining satisfaction of the conditions set forth in Section 9.2; provided, however, that if Closing shall occur, then all matters disclosed pursuant to any such addition, supplement or amendment at or prior to Closing shall be waived and Purchaser shall not be entitled to make a claim with respect thereto pursuant to the terms of this Agreement or otherwise.

(the “Agreed Accounting Firm”).

If Seller terminates this Agreement (or for purposes of pursing specific performance pursuant to clause (B) of this sentence, is entitled to terminate this Agreement) pursuant to Section 11.1(b)(i), Section 11.1(c)(i) or Section 11.1(c)(iii), then Seller shall be entitled to (A) promptly receive from the Escrow Agent the Escrow Funds for the sole account and use of Seller as liquidated damages hereunder, or (B) pursue any and all remedies as may be available to Seller at law or in equity, including specific performance. Seller and Purchaser acknowledge and agree that (x) Seller’s actual damages upon the event of such a termination are difficult to ascertain with any certainty, (y) the Escrow Funds are a fair and reasonable estimate by the parties of such aggregate actual damages of Seller and (z) such liquidated damages do not constitute a penalty. If Purchaser terminates this Agreement (or for purposes of pursing specific performance pursuant to clause (A) of this sentence, is entitled to terminate this Agreement) pursuant to Section 11.1(b)(i) or Section 11.1(d)(i), then Purchaser shall be entitled to (A) exercise any rights to specific performance of this Agreement to which Purchaser may be entitled at law or in equity or (B) terminate this Agreement and receive the entirety of the Escrow Funds for the sole account and use of Purchaser; provided, however, that in the case of a termination by Purchaser pursuant to Section 11.1(b)(i), Purchaser shall only be entitled to elect the remedy contemplated by clause (A) if such termination occurs as a result of a breach of this Agreement by Seller which breach has been the principal cause of, or resulted in, the failure of the Closing to occur on or before the Termination Date. Except as set forth above, in the event that this Agreement is terminated for

59

any other reason, Purchaser shall be entitled to promptly receive from the Escrow Agent the entirety of the Escrow Funds for the account of Purchaser. If the Closing does not occur for any reason whatsoever, Purchaser shall not be entitled to recover any monetary damages; provided, if (1) Seller refuses to close when obligated to do so under the terms of this Agreement and (2) Purchaser elects the remedy of specific performance but such remedy is not awarded by courts of competent jurisdiction, then the Escrow Funds shall be released from the Escrow Account to Purchaser (or promptly paid by Seller to Purchaser if previously released to Seller) and Purchaser shall be entitled to recover such direct, actual monetary damages as are available at law; provided, however, that Purchaser’s recovery for such damages shall be limited to an amount equal to $20,000,000. Notwithstanding anything to the contrary in this Article 11, in the event that a party seeks and prevails in a claim for specific performance in accordance with this Section 11.2, it shall also be entitled to recover its attorneys’ fees incurred in bringing its claim for specific performance and enforcing a judgment in connection therewith. The parties hereto agree that specific performance is a remedy expressly negotiated by the parties and Seller and Purchaser agree to support the application of, and not challenge, the enforceability of specific performance as a remedy as further described in this Section 11.2. Except as set forth in this Section 11.2 (including Purchaser’s specific performance remedies contemplated hereby), once this Agreement is terminated, neither Party shall have the right of specific performance with respect to the closing of the transactions contemplated by this Agreement and Seller and its Affiliates shall be free immediately to enjoy all rights of ownership of the Assets and to sell, transfer, encumber or otherwise dispose of any of the Assets to any Person without any restriction under this Agreement.

ARTICLE 12

POST-CLOSING OBLIGATIONS; INDEMNIFICATION; LIMITATIONS; DISCLAIMERS AND WAIVERS

Section 12.1 Receipts. Except as otherwise provided in this Agreement, subject to Section 12.3(ii) and Section 12.3(iii), any Hydrocarbons produced from or attributable to the Assets (and all products and proceeds attributable thereto) and any other income, proceeds, receipts and credits attributable to the Assets which are not reflected in the adjustments to the Cash Consideration following the final adjustment pursuant to Section 10.4(b) shall be treated as follows: (a) all Hydrocarbons produced from or attributable to the Assets (and all products and proceeds attributable thereto) and all other income, proceeds, receipts and credits earned with respect to the Assets to which Purchaser is entitled under Section 2.4 shall be the sole property and entitlement of Purchaser, and, to the extent received by Seller, Seller shall fully disclose, account for and remit the same promptly to Purchaser, and (b) all Hydrocarbons produced from or attributable to the Assets (and all products and proceeds attributable thereto) and all other income, proceeds, receipts and credits earned with respect to the Assets to which Seller is entitled under Section 2.4 shall be the sole property and entitlement of Seller and, to the extent received by Purchaser, Purchaser shall fully disclose, account for and remit the same promptly to Seller.

Section 12.2 Expenses. Except as otherwise provided in this Agreement, subject to Section 12.3(ii) and Section 12.3(iii), any Property Costs which are not reflected in the adjustments to the Cash Consideration following the final adjustment pursuant to Section 10.4(b) shall be treated as follows: (a) all Property Costs for which Seller is responsible under Section

60

2.4 shall be the sole obligation of Seller and Seller shall promptly pay, or if paid by Purchaser, promptly reimburse Purchaser for and hold Purchaser harmless from and against same; and (b) all Property Costs for which Purchaser is responsible under Section 2.4 shall be the sole obligation of Purchaser, and Purchaser shall promptly pay, or if paid by Seller, promptly reimburse Seller for and hold Seller harmless from and against same. Seller is entitled to resolve all joint interest audits and other audits of Property Costs covering periods for which Seller is wholly responsible (provided, however, that Purchaser shall have the right to participate in such audit) and Purchaser is entitled to resolve all joint interest audits and other audits of Property Costs covering periods for which Purchaser is in whole or in part responsible; provided that Purchaser shall not agree to any adjustments to previously assessed costs for which Seller is liable without the prior written consent of Seller, such consent not to be unreasonably withheld or delayed. Purchaser shall provide Seller with a copy of all applicable audit reports and written audit agreements received by Purchaser and relating to periods for which Seller is partially responsible.

Section 12.3 Assumed Seller Obligations. Subject to the indemnification by Seller under Section 12.5, 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 of the obligations and liabilities of Seller, known or unknown, attributable to or resulting from the use, maintenance, ownership, or operation of the Assets, regardless of whether such obligations or liabilities arose prior to, on or after the Effective Time (all of said obligations and liabilities, subject to the exclusions below, herein being referred to as the “Assumed Seller Obligations”); provided, however, that the Assumed Seller Obligations shall not include, and Purchaser shall have no obligation to assume, any obligations or liabilities of Seller to the extent that they are (such excluded obligations and liabilities, the “Excluded Seller Obligations”):

(i) attributable to or arise out of the Excluded Assets;

(ii) for a period of 24 months after Closing, the continuing responsibility of Seller under Section 12.1 or Section 12.2;

(iii) for a period of 24 months after Closing, Property Costs for which Seller is responsible pursuant to Section 2.4(b); or

(iv) owed to (1) Seller’s limited partners or other equity owners, (2) Seller’s employees for work performed with respect to the Assets prior to the Effective Time, (3) Seller’s Affiliates, (4) Seller’s lenders, and (5) the Internal Revenue Service arising from Seller’s federal income tax obligations.

Section 12.4 Survival and Limitations; Exclusive Remedy.

(a) The representations and warranties contained in Articles 6 (other than the Fundamental Representations) shall terminate nine (9) months after Closing. The representations and warranties contained in Section 6.1, Section 6.2, Section 6.3, Section 6.5, Section 7.1, Section 7.2, Section 7.3, Section 7.5 and Section 7.8 (collectively, the “Fundamental Representations”) shall survive until the expiration of the applicable statute of limitations period. Upon the termination of a representation or warranty in accordance with the foregoing, such

61

representation or warranty 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 and delivery and recordation of the Conveyances hereunder until such covenants and agreements have been fully performed, and if any such covenants or agreements shall be breached, until the applicable statute of limitation period in respect of such breach has elapsed.

(b) No party hereto shall have any indemnification obligation pursuant to this Article 12 or otherwise in respect of any representation, warranty, covenant (other than the exclusivity covenants set forth in Section 8.9) or agreement 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 in respect of such representation, warranty, covenant or agreement is being sought on or before the expiration of the applicable survival period set forth in Section 12.4(a). If an Indemnified Party delivers a Claim Notice to an Indemnifying Party before the expiration of the applicable survival period set forth in Section 12.4(a), then the applicable representation, warranty, covenant or agreement 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.

(c) Seller shall not have any liability for any indemnification under this Agreement, nor any liability for breach of any representations or warranties or covenants under this Agreement, until and unless (i) the amount of the liability for any individual claim or series of claims arising out of the same or similar set of facts, for which a Claim Notice is delivered by Purchaser exceeds $100,000 (“Individual Indemnity Threshold”), and (ii) the aggregate amount of the liabilities for all claims for which Claim Notices are delivered by Purchaser exceeds one and one-half percent (1.5%) of the Total Allocated Value, and then only to the extent of such excess (the “Aggregate Indemnity Deductible”); for the avoidance of doubt, claims for which Claim Notices are delivered by Purchaser which do not meet the Individual Indemnity Threshold shall not be included in reaching the Aggregate Indemnity Deductible.

(d) Except as expressly provided elsewhere in this Agreement, Seller shall not be required to indemnify Purchaser, or otherwise be liable for breaching any representations, warranties, or covenants under this Agreement, for aggregate damages in excess of (i) with respect to the Fundamental Representations, the representations set forth in Section 6.7 and indemnification by Seller pursuant to Section 12.5(a)(ii) and Section 12.5(a)(iii), one hundred percent (100%) of the Total Allocated Value, and (ii) with respect to all other matters not included within clause (i), twenty percent (20%) of the Total Allocated Value. For the avoidance of doubt, nothing in this Agreement shall be deemed to limit or restrict the right of the Purchaser Indemnified Persons to recover any amounts in connection with any claim or action based upon fraud.

(e) The sole and exclusive remedy of Purchaser with respect to the Assets shall be pursuant to the express provisions of this Agreement and any agreement delivered between the parties at Closing. Without limitation of the foregoing, if the Closing occurs, the

62

sole and exclusive remedy of Purchaser for any and all (a) claims relating to any representations, warranties, covenants and agreements that are contained in this Agreement or in any certificate delivered at Closing, (b) other claims pursuant to or in connection with this Agreement and (c) other claims relating to the Assets and the purchase and sale thereof, shall be any right to indemnification from such claims that is expressly provided in this Agreement and any other agreement delivered between the parties at Closing, and if no such right of indemnification is expressly provided, then such claims are hereby waived to the fullest extent permitted by law.

(f) For federal income tax purposes, the Parties agree to treat (and shall cause each of their respective Affiliates to treat) any indemnity payment under this Agreement as an adjustment to the Cash Consideration payable to Seller hereof unless a final and nonappealable determination by an appropriate Governmental Body (which shall include the execution of an IRS Form 870-AD or successor form) provides otherwise.

Section 12.5 Indemnification by Seller.

(a) Subject to the terms, conditions, and limitations of this Article 12, from and after the Closing, Seller shall indemnify, defend and hold harmless Purchaser and its directors, officers, employees, stockholders, members, agents, consultants, advisors and other representatives (including legal counsel, accountants and financial advisors) and Affiliates and the permitted successors and 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:

(i) any breach of any representation or warranty of Seller contained in this Agreement or in any certificate furnished by or on behalf of Seller in connection with this Agreement;

(ii) any breach or nonfulfillment of or failure to perform any covenant or agreement of Seller contained in this Agreement or in any certificate furnished by or on behalf of Seller in connection with this Agreement; and

(iii) the Excluded Seller Obligations.

Section 12.6 Indemnification by Purchaser. Excepting matters to the extent for which Purchaser would be entitled to indemnification under Section 12.5, from and after the Closing, subject to the terms and conditions of this Article 12, Purchaser shall indemnify, defend and hold harmless Seller and its directors, officers, employees, agents, consultants, stockholders, advisors and other representatives (including legal counsel, accountants and financial advisors), and Seller’s permitted successors and assigns of this Agreement and Affiliates (collectively, 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:

(a) any breach of any representation or warranty of Purchaser contained in this Agreement or in any certificate furnished by or on behalf of Purchaser to Seller in connection with this Agreement;

63

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

(c) the ownership, use or operation of the Assets after the Effective Time;

(d) the Assumed Seller Obligations; and

(e) Environmental Laws, Environmental Defects, Environmental Liabilities, the release of materials into the environment or protection of human health, safety, natural resources or the environment, or any other environmental condition of the Assets, whether arising prior to, on or after the Effective Time.

Section 12.7 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 12.5 or to a Seller Indemnified Person under Section 12.6 (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 12, 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 12.7, 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.

(b) 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, if the Indemnified Party’s counsel shall have reasonably opined that there is a conflict of interest that would make it inappropriate under applicable standards of professional conduct to have common counsel for the Indemnifying Party and the Indemnified Party, then the Indemnifying Party shall pay the reasonable fees of counsel to the Indemnified Party (who shall not be the same as the opining counsel), it being understood and agreed, however, 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.

64

(c) 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, conditioned or delayed). 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.

(d) 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 a Claim Notice with respect thereto to the Indemnifying Party pursuant to this Article 12 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).

(e) 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 12 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.

The Company will notify Investor promptly upon the Registration Statement and each post-effective amendment thereto being declared effective by the SEC and advise Investor that the form of Prospectus contained in the Registration Statement or post-effective amendment thereto, as the case may be, at the time of effectiveness meets the requirements of Section 10(a) of the Securities Act or that it intends to file a Prospectus pursuant to Rule 424(b) under the Securities Act that meets the requirements of Section 10(a) of the Securities Act;

(ii) furnish to Investor and its representatives and counsel in advance of filing the Registration Statement or the Prospectus or any amendment or supplement thereto a copy of a reasonably complete draft of such Registration Statement or Prospectus or any amendment or supplement thereto, and provide Investor the opportunity to object to any information pertaining to Investor and its plan of distribution that is contained therein and make necessary corrections reasonably requested by Investor with respect to such information or plan of distribution prior to filing the Registration Statement or the Prospectus or any amendment or supplement thereto;

(iii) furnish to Investor with respect to the Registrable Securities registered under the Registration Statement such number of copies of the Registration Statement and the Prospectus (including supplemental prospectuses) filed with the SEC in conformance with the requirements of the Securities Act and other such documents as Investor may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Registrable Securities by Investor;

(iv) make any blue sky filings or other qualifications under securities laws of such jurisdictions as Investor shall reasonably request and shall advise Investor, promptly, of the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction;

(v) pay the expenses incurred by the Company and Investor in complying with this Agreement, including, without limitation, all registration and filing fees, FINRA fees, exchange listing fees, fees of transfer agents and registrars, printing expenses, fees and disbursements of counsel and independent reserve engineers for the Company, blue sky fees and expenses and the expense of any special audits incident to or required by any such registration (but excluding attorneys’ fees of Investor and excluding any and all underwriting discounts and selling commissions applicable to the sale of Registrable Securities by Investor);

4

(vi) advise Investor, promptly after it shall receive notice or obtain knowledge of the issuance of any stop order by the SEC delaying or suspending the effectiveness of the Registration Statement or of the initiation of any proceeding for that purpose; and it will promptly use its commercially reasonable best efforts to prevent the issuance of any stop order or to obtain its withdrawal at the earliest possible moment if such stop order should be issued;

(vii) upon request and subject to appropriate confidentiality obligations, furnish to Investor copies of any and all transmittal letters or other correspondence with the SEC or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to the Registration Statement;

(x) in connection with an Underwritten Offering, use commercially reasonable efforts to provide to Investor a copy of any auditor “comfort” letters, customary legal opinions or reports of the independent petroleum engineers of the Company relating to the oil and gas reserves of the Company, in each case that have been provided to the Managing Underwriter in connection with the Underwritten Offering;

(xi) make available upon reasonable notice at reasonable times and for reasonable periods for inspection by Investor and any underwriter or broker participating in any disposition of Registrable Securities and any attorney, accountant or other agent retained by any such Investor, broker or underwriter (collectively, the “Inspectors”), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the “Records”), and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such Inspector in connection with a Registration Statement; provided, that the Company need not disclose any non-public information to any such person unless and until such person has entered into a confidentiality agreement with the Company; and

(xii) with a view to making available to Investor the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit Investor to sell Registrable Securities to the public without registration, the Company covenants and agrees to use its commercially reasonable best efforts to: (i) make and keep public

5

information available, as those terms are understood and defined in Rule 144, until the earlier of (A) such date as all of the Registrable Securities qualify to be resold immediately without restriction, and without regard for whether the Company has filed and made available the information contemplated by Rule 144(c)(1), pursuant to Rule 144 or (B) such date as all of the Registrable Securities shall have been resold pursuant to Rule 144 (and may be further resold without restriction); (ii) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and under the Exchange Act; and (iii) furnish to Investor upon request, as long as Investor owns any Registrable Securities, (A) a written statement by the Company as to whether it has complied with the reporting requirements of the Securities Act and the Exchange Act, (B) a copy of the Company’s most recent annual report on Form 10-K or quarterly report on Form 10-Q, and (C) such other information as may be reasonably requested in order to avail Investor of any rule or regulation of the SEC that permits the selling of any such Registrable Securities without registration.

(c) The Company understands that Investor disclaims being an underwriter but acknowledges that a determination by the SEC that Investor is deemed an underwriter shall not relieve the Company of any obligations it has hereunder.

(d) If, on or after April 1, 2019, the Investor elects to dispose of Registrable Securities under a Registration Statement pursuant to an Underwritten Offering and reasonably expects gross proceeds of at least $20,000,000 from such Underwritten Offering, then the Company shall, at the request of Investor, enter into an underwriting agreement in a form as is customary in Underwritten Offerings of securities by the Company with an underwriter or underwriters selected pursuant to this Section 2 and shall take all such other reasonable actions as are requested by the Managing Underwriter of such Underwritten Offering and/or Investor in order to expedite or facilitate the disposition of such Registrable Securities; provided, however, that the Company shall have no obligation to facilitate or participate in more than one (1) Underwritten Offering pursuant to this Agreement in any 180-day period or more than four (4) Underwritten Offerings pursuant to this Agreement; provided further, that an Underwritten Offering shall not count against such limit unless and until the Requesting Holder(s) are able to sell at least seventy-five percent (75%) of the Registrable Shares requested to be included in such Underwritten Offering. The Company shall select the Managing Underwriter and any other underwriters in connection with any Underwritten Offering. The Investor shall determine the pricing of the Registrable Securities offered pursuant to any Underwritten Offering and the applicable underwriting discounts and commissions.

(e) In connection with any Underwritten Offering contemplated by Section 2(d), the underwriting agreement into which the Investor and the Company shall enter into shall contain such representations, covenants, indemnities and other rights and obligations as are customary in underwritten offerings. Investor shall not be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties, agreements or indemnities regarding Investor, Investor’s title in the securities being registered on its behalf, Investor’s authority to enter into such underwriting agreement and to sell, and information provided by Investor for inclusion in the Registration Statement relating thereto and its ownership of, the securities being registered on its behalf, its intended method of distribution and any other representation required by law.

6

(f) The Company, at its sole cost, shall remove any legend ordinarily included on restricted securities of the Company (or instruct its transfer agent to so remove such legend) from the certificates or book-entries evidencing Registrable Securities if such Common Stock (i) is sold pursuant to an effective registration statement under the Securities Act, (ii) is sold or transferred pursuant to Rule 144 (if the transferor is not an Affiliate of the Company) or (iii) is eligible for sale under Rule 144. Investor agrees to provide the Company, its counsel and/or the transfer agent with evidence reasonably requested by it in order to cause the removal of such legend, including, as may be appropriate, any information the Company deems necessary to determine that the legend is no longer required under the Securities Act or applicable state laws, including a certification that the holder is not an Affiliate of the Company (and a covenant to inform the Company if it should thereafter become an Affiliate and to consent to exchange any certificates or instruments representing the Common Stock for ones bearing an appropriate restrictive legend) and regarding the length of time the Common Stock has been held. Any fees (with respect to the transfer agent, Company counsel or otherwise) associated with the issuance of any legal opinion required by the Company’s transfer agent or the removal of such legend shall be borne by the Company. If a legend is no longer required pursuant to the foregoing, the Company will use commercially reasonable efforts to, no later than five (5) days following the delivery by Investor to the Company or the transfer agent (with notice to the Company) of a legended certificate or instrument representing the Common Stock (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer) and any representation letter or certification as may be requested by the Company, deliver or cause to be delivered to such Company a certificate or instrument (as the case may be) representing such Common Stock that is free from all restrictive legends.

3. Transfer of Shares After Registration; Suspension.

(a) Except in the event that Section 3(b) applies, the Company shall: (i) if deemed necessary or advisable by the Company, prepare and file from time to time with the SEC a post-effective amendment to the Registration Statement or a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that such Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and so that, as thereafter delivered to Investor, such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; (ii) provide Investor copies of any documents filed pursuant to clause (i) above; and (iii) upon request, inform Investor that the Company has complied with its obligations in Section 2(b)(i) (or that, if the Company has filed a post-effective amendment to the Registration Statement which has not yet been declared effective, the Company will notify Investor to that effect, will use its commercially reasonable best efforts to secure the effectiveness of such post-effective amendment as promptly as possible and will promptly notify Investor pursuant to Section 2(b)(i) when the amendment has become effective).

7

(b) In the event: (i) of any request by the SEC during the period of effectiveness of the Registration Statement for amendments or supplements to the Registration Statement or related Prospectus or for additional information; (ii) of the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iii) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation of any proceeding for such purpose; or (iv) of any event or circumstance which necessitates the making of any changes in the Registration Statement or Prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; then the Company shall promptly deliver a certificate in writing to Investor (the “Suspension Notice”) to the effect of the foregoing and, upon receipt of such Suspension Notice, Investor will refrain from selling any Registrable Securities pursuant to the Registration Statement (a “Suspension”) until Investor is advised in writing by the Company that the current Prospectus may be used, and has received copies from the Company of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any such Prospectus. In the event of any Suspension, the Company will use its commercially reasonable best efforts to cause the use of the Prospectus so suspended to be resumed as soon as practicable after delivery of a Suspension Notice to Investor. In addition to and without limiting any other remedies (including, without limitation, at law or at equity) available to the Company and Investor, the Company and Investor shall be entitled to specific performance in the event that the other party fails to comply with the provisions of this Section 3(b).

(c) If a Suspension is not then in effect, Investor may sell Registrable Securities under the Registration Statement, provided that it complies with any applicable prospectus delivery requirements. Upon receipt of a request therefor, the Company will provide an adequate number of current Prospectuses to Investor and to any other parties reasonably requiring such Prospectuses.

4. Indemnification.

(a) The Company agrees to indemnify and hold harmless each Selling Stockholder from and against any losses, claims, damages or liabilities to which such Selling Stockholder may become subject (under the Securities Act or otherwise) insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon (i) any untrue statement of a material fact in the Registration Statement or omission to state a material fact required to be stated therein or

8

necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, (ii) any inaccuracy in the representations and warranties of the Company contained in this Agreement or the failure of the Company to perform its obligations hereunder or (iii) any failure by the Company to fulfill any undertaking included in the Registration Statement, and the Company will reimburse such Selling Stockholder for any reasonable legal expense or other actual accountable out-of-pocket expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of, or is based upon, an untrue statement in the Registration Statement or omission to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Selling Stockholder specifically for use in preparation of the Registration Statement or the failure of such Selling Stockholder to comply with its covenants and agreements contained herein or any statement or omission in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Selling Stockholder prior to the pertinent sale or sales by the Selling Stockholder. The indemnity provided in this Section 4(a) shall remain in full force and effect regardless of any investigation made by or on behalf of a Selling Stockholder and shall survive any transfer of Registrable Securities by such Selling Stockholder.

(b) Investor agrees to indemnify and hold harmless the Company (and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, each officer of the Company who signs the Registration Statement and each director of the Company) from and against any losses, claims, damages or liabilities to which the Company (or any such officer, director or controlling person) may become subject (under the Securities Act or otherwise), to the extent that such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, (i) any failure by Investor to comply with the covenants and agreements contained herein or (ii) any untrue statement of a material fact contained in the Registration Statement if, and only if, such untrue statement was made in reliance upon and in conformity with written information furnished by or on behalf of Investor specifically for use in preparation of the Registration Statement, and Investor will reimburse the Company (or such officer, director or controlling person, as the case may be), for any reasonable legal expense or other reasonable actual accountable out-of-pocket expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim. The obligation to indemnify and reimburse expenses shall be limited to the net amount of the proceeds received by Investor from the sale of the Registrable Securities pursuant to the Registration Statement.

(c) Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in respect of which indemnity is to be sought against an indemnifying person pursuant to this Section 4, such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 4 (except to the extent that

9

such omission materially and adversely affects the indemnifying party’s ability to defend such action) or from any liability otherwise than under this Section 4. Subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified person, the indemnifying person shall be entitled to participate therein, and, to the extent that it shall elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, shall be entitled to assume the defense thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the indemnifying person to such indemnified person of its election to assume the defense thereof (unless it has failed to assume the defense thereof and appoint counsel reasonably satisfactory to the indemnified party), such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof; provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate, in the reasonable opinion of counsel to the indemnified person, for the same counsel to represent both the indemnified person and such indemnifying person or any Affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel (who shall not be the same as the opining counsel) at the expense of such indemnifying person; provided, however, that no indemnifying person shall be responsible for the fees and expenses of more than one separate counsel (together with appropriate local counsel) for all indemnified parties. In no event shall any indemnifying person be liable in respect of any amounts paid in settlement of any action unless the indemnifying person shall have approved the terms of such settlement; provided that such consent shall not be unreasonably withheld, conditioned or delayed. No indemnifying person shall, without the prior written consent of the indemnified person, effect any settlement of any pending or threatened proceeding in respect of which any indemnified person is or could reasonably have been a party and indemnification could have been sought hereunder by such indemnified person, unless such settlement includes an unconditional release of such indemnified person from all liability on claims that are the subject matter of such proceeding.

(d) If the indemnification provided for in this Section 4 is unavailable to or insufficient to hold harmless an indemnified party under subsections 4(a) or 4(b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and Investor on the other in connection with the statements or omissions or other matters which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, in the case of an untrue statement, whether the untrue statement relates to information supplied by the Company on the one hand or Investor on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement. The Company and Investor agree that it would not be just and equitable if contribution pursuant to this subsection 4(d) were determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to above in this subsection 4(d). The amount paid or

10

payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection 4(d) will be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection 4(d), Investor will not be required to contribute any amount in excess of the amount by which the net amount received by Investor from the sale of the Registrable Securities to which such loss relates exceeds the amount of any damages which Investor has otherwise been required to pay to the Company by reason of such untrue statement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The parties to this Agreement hereby acknowledge that they are sophisticated business persons who were represented by counsel during the negotiations regarding the provisions hereof including, without limitation, the provisions of this Section 4, and are fully informed regarding said provisions. They further acknowledge that the provisions of this Section 4 fairly allocate the risks in light of the ability of the parties to investigate the Company and its business in order to assure that adequate disclosure is made in the Registration Statement as required by the Securities Act and the Exchange Act.

(f) The obligations of the Company and of Investor under this Section 4 shall survive completion of any offering of Registrable Securities pursuant to the Registration Statement. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a complete and unconditional release from all liability in respect to such claim or litigation.

5. Information Available. So long as the Registration Statement is effective covering the resale of Registrable Securities owned by Investor, the Company will furnish (or, to the extent such information is available electronically through the Company’s filings with the SEC, the Company will make available via the SEC’s EDGAR system or any successor thereto) to Investor:

(a) as soon as practicable after it is available, one copy of (i) its Annual Report to Stockholders (which Annual Report shall contain financial statements audited in accordance with generally accepted accounting principles by a national firm of certified public accountants) and (ii) if not included in substance in the Annual Report to Stockholders, its Annual Report on Form 10-K (the foregoing, in each case, excluding exhibits);

(b) upon the request of Investor, all exhibits excluded by the parenthetical to subparagraph (a)(ii) of this Section 5 as filed with the SEC and all other information that is made available to stockholders; and

11

(c) upon the reasonable request of Investor, an adequate number of copies of the Prospectuses to supply to any other party requiring such Prospectuses; and the Company, upon the reasonable request of Investor, will meet with Investor or its representatives at the Company’s headquarters during the Company’s normal business hours to discuss all information relevant for disclosure in the Registration Statement covering the Registrable Securities and will otherwise reasonably cooperate with Investor’s investigation for the purpose of reducing or eliminating Investor’s exposure to liability under the Securities Act, including the reasonable production of information at the Company’s headquarters; provided, that the Company shall not be required to disclose any confidential information to or meet at its headquarters with Investor until and unless Investor shall have entered into a confidentiality agreement in form and substance reasonably satisfactory to the Company with the Company with respect thereto.

6. Regulation M. The Company will not take any direct or indirect action prohibited by Regulation M under the Exchange Act or that would cause Investor to be prohibited or limited under Regulation M or any similar rule from selling any shares of Common Stock pursuant to the Registration Statement.

7. Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Agreement may be assigned by Investor to a party that acquires, other than pursuant to the Registration Statement or Rule 144, any of the Registrable Securities, or to any Affiliate of Investor that acquires any Registrable Securities.

PLAN OF DISTRIBUTION

We are registering for resale by the selling stockholders and certain transferees a total of shares of Common Stock, of which shares are issued and outstanding and up to shares are issuable upon exercise of warrants. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of Common Stock, although we may receive up to $ upon the exercise of all of the warrants by the selling stockholders. We will bear all fees and expenses incident to our obligation to register the shares of Common Stock. If the shares of Common Stock are sold through broker-dealers or agents, the selling stockholder will be responsible for any compensation to such broker-dealers or agents.

The selling stockholders may pledge or grant a security interest in some or all of the shares of Common Stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock from time to time pursuant to this prospectus.

The selling stockholders also may transfer and donate the shares of Common Stock in other circumstances in which case the transferees, donees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus.

The selling stockholders may use any one or more of the following methods when selling the shares of Common Stock offered by this prospectus:

The selling stockholders may set the price or prices of their shares of Common Stock at:

In connection with sales through one or more broker-dealers or agents, such broker-dealers or agents may receive compensation in the form of discounts, concessions or commissions from the selling stockholders and may receive commissions from the purchasers of the shares of Common Stock for whom they act as broker-dealer or agent or to whom they sell as principal (which discounts, concessions or commissions as to particular broker-dealers or agents may be in excess of those customary in the types of transaction involved). Any broker-dealer or agent participating in any such sale may be deemed to be an “underwriter” within the meaning of the Securities Act and will be required to deliver a copy of this prospectus to any person who purchases any share of Common Stock from or through such broker-dealer or agent. [We have been advised that, as of the date hereof, none of the selling stockholders have made any arrangements with any broker-dealer or agent for the sale of their shares of Common Stock.]

The selling stockholder and any broker-dealer participating in the distribution of the shares of Common Stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any profits realized by the selling stockholders and any commissions paid, or any discounts or concessions allowed to any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. In addition, any shares of Common Stock covered by this prospectus that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus. A selling stockholder may also transfer, devise or gift the shares of Common Stock by other means not covered in this prospectus in which case the transferee, devisee or giftee will be the selling stockholder under this prospectus.

If required at the time a particular offering of the shares of Common Stock is made, a prospectus supplement or, if appropriate, a post-effective amendment to the shelf registration statements of which this prospectus is a part, will be distributed which will set forth the aggregate amount of shares of Common Stock being offered and the terms of the offering, including the name or names of any broker-deals or agents, any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers.

If underwriters are used in the sale of any securities, an underwriting agreement will be executed with the underwriter at the time of sale and we will identify any underwriters or agents and describe their compensation in a prospectus supplement used to make resales of the securities to the public. In connection with the sale of the securities, the selling securityholders, or the purchasers of securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for which they may act as agent. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis and a dealer will purchase securities as a principal, and may then resell the securities at varying prices to be determined by the dealer.

Under the securities laws of some states, the shares of Common Stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with. There can be no assurance that any selling stockholder will sell any or all of the shares of Common Stock registered pursuant to the shelf registration statement, of which this prospectus forms a part.

The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of Common Stock by the selling stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of Common Stock to engage in market-making activities with respect to the shares of Common Stock. All of the foregoing may affect the marketability of the shares of Common Stock and the ability of any person or entity to engage in market-making activities with respect to the shares of Common Stock.

We will bear all expenses of the registration of the shares of Common Stock including, without limitation, Securities and Exchange Commission filing fees and expenses of compliance with the state securities of “blue sky” laws. The selling stockholders will pay all underwriting discounts and selling commissions and expenses, brokerage fees and transfer taxes, as well as the fees and disbursements of counsel to and experts for the selling stockholders, if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act, in accordance with the registration rights agreement or the selling stockholder will be entitled to contribution. We will be indemnified by the selling stockholders against civil liabilities, including liabilities under the Securities Act that may arise from any written information furnished to us by the selling stockholders for use in this prospectus, in accordance with the registration rights agreement or will be entitled to contribution. Once sold under this shelf registration statement, of which this prospectus forms a part, the shares of Common Stock will be freely tradable in the hands of persons other than our affiliates.
