Section 3.2    Adjustments to Cash Consideration .

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 to have one of the following remedies apply:

(i)    subject to the Defect Threshold, 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

25

(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 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 date that the Title Defect is cured, 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. 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 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 Asset in the Asset Exhibits affected by Title Benefits reported under Section  4.4(b) , subject to the amount of the aggregate Title Benefits (the “ Title Benefit Amount ”), such Title Benefit Amount 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;

26

(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 the Asset Exhibits 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 the Asset Exhibits;

(iv)    if the Title Defect results from Sellers owning fewer Net Mineral Acres in such Title Defect Property than the Net Mineral Acres specified therefor in the Asset Exhibits, 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 Net Mineral Acres and the denominator of which is the number of Net Mineral Acres specified for such Title Defect Property in the Asset Exhibits;

(v)    if the Title Defect results from any matter not described in subsections (i), (ii) (iii) or (iv) 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

(vi)    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.

27

(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 Lease, Unit, Prospect, Well or Assigned Wellbore, the amount by which the value of the affected Lease, Unit, Prospect, Well or Assigned Wellbore is enhanced by virtue of (A) Seller having a greater Net Revenue Interest or greater number of Net Mineral Acres in such Lease, Unit, Prospect, Well or Assigned Wellbore than the Net Revenue Interest or Net Mineral Acres specified therefor in the Asset Exhibits, (B) Seller having a lesser working interest in such Lease, Unit, Prospect, Well or Assigned Wellbore than the working interest specified therefor in the Asset Exhibits, or (C) such Lease, Unit, Prospect, Well or Assigned Wellbore 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 Lease, Unit, Prospect, Well or Assigned Wellbore 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 Lease, Unit, Prospect, Well or Assigned Wellbore, the Title Benefit Amount with respect to such affected Lease, Unit, Prospect, Well or Assigned Wellbore shall be determined in the manner provided in Section  4.4(g) .

(iii)    If the Title Benefit Amount results from Seller having a greater Net Revenue Interest (without a corresponding increase in working interest) or greater number of Net Mineral Acres in such Lease, Unit, Prospect, Well or Assigned Wellbore than the Net Revenue Interest or Net Mineral Acres specified therefor in the Asset Exhibits, the Title Benefit Amount shall be equal to the product obtained by multiplying the Allocated Value of such Lease, Unit, Prospect, Well or Assigned Wellbore by a fraction, the numerator of which is the increase in the Net Revenue Interest or Net Mineral Acres, as applicable, and the denominator of which is the Net Revenue Interest or Net Mineral Acres, as applicable, specified for such Lease, Unit, Prospect, Well or Assigned Wellbore in the Asset Exhibits.

(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 all Title Defect Amounts and Title Benefit Amounts prior to Closing. If Seller and Purchaser are unable to agree by Closing, the Title Defect Amounts and Title Benefit Amounts in dispute 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, as selected by mutual agreement of Purchaser and Seller within fifteen (15) Business Days after the end of the Cure Period (the “ Title Expert ”). The Title Expert’s determination shall be made within fifteen (15) Business

28

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) and Section  4.4(h) and may consider such other matters as in the opinion of the Title Expert are necessary or helpful to make 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 shall act as an expert for the limited purpose of determining the specific disputed Title Defect Amounts and Title Benefit Amounts 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 Title Defect Amount or a Title Benefit Amount, (i) Purchaser shall pay to Seller the amount, if any, so awarded by the Title Expert to Seller, plus interest payable on such amount at the Agreed Interest Rate from (but not including) the Closing Date to (and including) the date on which such amount is paid to Seller and (ii) Seller shall pay to Purchaser the amount, if any, so awarded by the Title Expert to Purchaser.

(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 unless the aggregate Title Defect Amount and Environmental Defect Amount exceeds an amount equal to three percent (3%) of the Total Allocated Value (the “ Defect Threshold ”), after which point adjustments to the Cash Consideration or other remedies shall be made or available to Purchaser from the first dollar of uncured Title Defects and uncured Environmental Defects.

Section 4.5    Casualty or Condemnation Loss.

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 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 (a) 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 (b) 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, VIOLATION OF A LEGAL REQUIREMENT OF SELLER.

29

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 Claim 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 and federal 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 or state 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 or state agencies, as applicable, of Seller’s assignment documents requiring federal or state approval in order for Purchaser to be recognized by the federal or state agencies as the owner of the Assets. Purchaser shall provide Seller with approved copies of the assignment documents and other state and federal 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;

(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

30

(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) with respect to any Assets where 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 American Society for Testing and Material Standard Practice Designation E1527-05, then Purchaser may request Seller’s consent to conduct additional Phase II environmental property assessments or such other activities intended to constitute the conduct of “all appropriate inquiries” under 30 CFR Part 312 (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

31

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 seven (7) days prior to the Closing Date at 5:00 p.m. Central Time (the “ Environmental Claim Date ”), Purchaser may notify Seller in writing of such Environmental Defect (an “ Environmental 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 (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 Seller disagrees with any of Purchaser’s assertions with respect to the existence of an Environmental Defect or the

32

Environmental Defect Amount, Purchaser and Seller will attempt to resolve the dispute prior to Closing. 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 ”). 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. In the event the parties have failed to resolve any dispute regarding an Environmental Defect at Closing, Seller shall retain the Asset affected by the Environmental Defect, in which event the Cash Consideration shall be reduced by an amount equal to the Allocated Value of such Asset. Thereafter, the Independent Expert shall render his 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 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 that the Independent Expert delivers written notice to Purchaser and Seller of his 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) in no event shall there be any adjustments to the Cash Consideration for any uncured Environmental Defect unless the aggregate Environmental Defect Amount attributable to all such Environmental Defects, taken together with the aggregate Title Defect Amounts attributable to all uncured Title Defects, exceeds the Defect Threshold, after which point adjustments to the Cash Consideration or other remedies shall be made or available to Purchaser from the first dollar of uncured Title Defects and uncured Environmental Defects. 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.

33

(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.

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. The indemnity obligation set forth in this Section  5.4 shall survive the Closing or termination of this Agreement.

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

44

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;

(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

45

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.

Notwithstanding the foregoing, Seller shall handle payment to the appropriate 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.

(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.

46

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.

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 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. 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)

In addition, at the election of Seller by written notice (a “ Lock-Up Termination Notice ”) to Purchaser at any time after January 1, 2019, the Lock-Up Restrictions will cease to apply if the simple average of the daily volume weighted average price of a share of Purchaser’s Common Stock, as reported by Bloomberg Financial, for each trading day over a period of five consecutive trading days beginning on or after December 24, 2018 is equal to or greater than $3.50.

(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 2.30% of the trailing 20-day average daily trading volume of Purchaser Common Stock (the “ Volume Limitation ”). The Volume Limitation will cease to apply for a given calendar month for Unrestricted Shares for such calendar month and any prior calendar month if the closing price of Purchaser Common Stock as reported by the NYSE American during such calendar month exceeds the applicable Reference Price for such calendar month for five consecutive trading days. Upon valid delivery of a Lock-Up Termination Notice, the Volume Limitation will cease to apply, provided that Seller shall not transfer more than $10 million of Purchaser Common Stock in one or more block trades in any calendar week without obtaining Purchaser’s prior written consent thereto, which consent shall not be unreasonably withheld.

(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 Sections 12.5(a)(ii) , 12.5(a)(iii) and 12.5(a)(iv) , 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, willful misrepresentation or willful breach.

(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 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.

58

(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 successors and permitted assigns of this Agreement of Purchaser (collectively, the “ Purchaser Indemnified Persons ”) from and against any and all Losses asserted against, resulting from, imposed upon, or incurred or suffered by any Purchaser Indemnified Person to the extent resulting from, arising out of or relating to:

(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;

(iii)    any failure to obtain the waiver or consent of each relevant Person with respect to any maintenance of uniform interest requirement applicable to the Assets, provided that Purchaser has not affirmatively requested a waiver or consent to such maintenance of uniform interest requirement (it being acknowledged and agreed by the parties that delivery of a letter-in-lieu or other notice advising any Person of an assignment contemplated hereby shall not be treated as an affirmative request by Purchaser unless Purchaser expressly seeks the waiver or consent of such Person related to any maintenance of uniform interest requirement applicable to the Asset that is the subject of such letter or notice); provided, however, that the indemnity obligations of Seller under this clause (iii) shall expire, on an Asset-by-Asset basis, at such time as Purchaser has been receiving revenues directly from the operator of such Asset for six consecutive months following the Closing (provided, however, that once an operator starts paying revenues to Purchaser, such 6-month period shall continue to run if the operator subsequently suspends Purchaser’s revenues for any reason unrelated to the maintenance of uniform interest requirements); and

(iv)    the Excluded Seller Obligations.

Section 12.6    Indemnification by Purchaser . Excepting matters 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

59

representatives (including legal counsel, accountants and financial advisors), and Seller’s successors, permitted 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;

(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

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

60

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.

(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

61

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.

4

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

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 each 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 the Investors copies of any documents filed pursuant to clause (i) above; and (iii) upon request, inform each 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 the 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 the Investor pursuant to Section 2(b)(i) when the amendment has become effective).

(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 the Investors (the “ Suspension Notice ”) to the effect of the foregoing and, upon receipt of such Suspension Notice, the Investors will refrain from selling any Registrable Securities pursuant to the Registration Statement (a “ Suspension ”) until the Investors are advised in writing by the Company that the current Prospectus may be used, and have received copies from the Company of any additional or supplemental filings that are incorporated or deemed incorporated by

5

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 the Investors. In addition to and without limiting any other remedies (including, without limitation, at law or at equity) available to the Company and the Investors, the Company and the Investors 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, each 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 each 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 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)    Each Investor severally (as to itself), and not jointly, 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

6

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 that 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 that Investor specifically for use in preparation of the Registration Statement, and that 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 the 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 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

7

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 the liable 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 the liable 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 the Investors 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 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), no Investor will be required to contribute any amount in excess of the amount by which the net amount received by that Investor from the sale of the Registrable Securities to which such loss relates exceeds the amount of any damages which that 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. The Investors’ obligations in this subsection to contribute are several and not joint.

(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 the Investors under this Section 4 shall survive completion of any offering of Registrable Securities pursuant to the

8

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 an 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 each 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 an 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

(c)    upon the reasonable request of an 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 an Investor, will meet with each 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 any Investor’s investigation for the purpose of reducing or eliminating the 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 an Investor until and unless that 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 an 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 an Investor that acquires any Registrable Securities. Any such permitted assignee will have all the rights of such Investor under this Agreement with respect to the Registrable Securities transferred.

9

8.      Required Questionnaire. Each Investor agrees to furnish to the Company a completed questionnaire in the form attached to this Agreement as Exhibit A (a “ Selling Holder Questionnaire ”). The Company shall not be required to include the Registrable Securities of an Investor in a Registration Statement and shall not be required to pay any liquidated or other damages hereunder to any such Investor who fails to furnish to the Company a fully completed Selling Holder Questionnaire at least three Business Days prior to the filing of the Registration Statement.

9.      Termination. This Agreement shall terminate and be of no further force or effect when there shall no longer be any Registrable Securities outstanding; provided, that the provisions of Subsection 2(b)(v) and Section 4 will survive any such termination.

10.      Counterparts. This Agreement may be executed and delivered (including by facsimile or email transmission) in counterparts, each of which shall be deemed an original instrument, but all such counterparts together shall constitute but one agreement. This Agreement may be signed by facsimile signature or other electronic delivery of an image file reflecting execution hereof and, if so signed: (i) may be relied on by each party as if the document were a manually signed original and (ii) will be binding on each party for all purposes.

11.      Notices. All notices which are required or may be given pursuant to this Agreement shall be sufficient in all respects if given in writing and delivered personally, by overnight courier service, by electronic mail, or by registered or certified mail, postage prepaid, as follows:

10

Each party may change its address for notice by notice to the other in the manner set forth above. All notices shall be deemed to have been duly given at the time of receipt by the party to which such notice is addressed.

12.      Remedies. Each holder of Registrable Securities, in addition to being entitled to exercise all rights granted by law, including recovery of damages, shall be entitled to specific performance of its rights under this Agreement. The Company acknowledges that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and the Company hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.

13.    Governing Law and Venue. THIS AGREEMENT AND THE LEGAL RELATIONS BETWEEN THE PARTIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS OTHERWISE APPLICABLE TO SUCH DETERMINATIONS.

14.      Waiver of Jury Trial. Each party acknowledges and agrees that any controversy which may arise under this Agreement is likely to involve complicated and difficult issues and, therefore, each such party irrevocably and unconditionally waives any right it may have to a trial by jury in respect of any legal action arising out of or relating to this Agreement or the transactions contemplated hereby. Each party to this Agreement certifies and acknowledges that (a) no representative of any other party has represented, expressly or otherwise, that such other party would not seek to enforce the foregoing waiver in the event of a legal action, (b) such party has considered the implications of this waiver, (c) such party makes this waiver voluntarily, and (d) such party has been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 14.

15.      Captions. The captions in this Agreement are for convenience only and shall not be considered a part of or affect the construction or interpretation of any provision of this Agreement.

16.      Successor and Assigns. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. The Company may assign this Agreement at any time in connection with a sale or acquisition of the Company, whether by merger, consolidation, sale of all or substantially all of the Company’s assets, or similar transaction, without the consent of the Investors; provided, that the successor or acquiring Person agrees in writing to assume all of the Company’s rights and obligations under this Agreement.

11

17.      Entire Agreement. This Agreement, together with the Purchase Agreement and the Exhibits and Schedules attached thereto and hereto, constitutes the entire agreement between the parties pertaining to the subject matter hereof, and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties pertaining to the subject matter hereof.

18.      Amendment, Modification and Waiver. The provisions of this Agreement may only be amended, modified, supplemented or waived with the prior written consent of the Company and the holders of a majority of the Registrable Securities. No waiver by any party or parties shall operate or be construed as a waiver in respect of any failure, breach or default not expressly identified by such written waiver, whether of a similar or different character, and whether occurring before or after that waiver. Except as otherwise set forth in this Agreement, no failure to exercise, or delay in exercising, any right, remedy, power or privilege arising from this Agreement shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

19.      No Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other person any legal or equitable right, benefit or remedy of any nature whatsoever, under or by reason of this Agreement; provided, however, the parties hereto hereby acknowledge that the persons specifically identified in Section 4 are express third-party beneficiaries of the obligations of the parties hereto set forth in Section 4.

20.      Severability. If any term or other provisions of this Agreement is held invalid, illegal or incapable of being enforced under any rule of law, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in a materially adverse manner with respect to either party; provided, however, that if any such term or provision may be made enforceable by limitation thereof, then such term or provision shall be deemed to be so limited and shall be enforceable to the maximum extent permitted by applicable Law.

(iii)    For purposes of those wells that were not completed as of the Effective Time, the parties shall allocate the costs of those wells as set forth on Schedule 2.4 .

(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

17

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) .

Section 2.5    Delivery and Maintenance of Records .

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, 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. Notwithstanding the foregoing, no Additional Consideration shall be due and payable at any time after the delivery of a Lock-up Termination Notice by Seller.

(d)     Limitation on Additional Consideration . Notwithstanding the foregoing, under no circumstances shall Purchaser issue shares of Purchaser Common Stock 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).

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:

19

(d)    Increased by the amount of all Property Costs and other costs attributable to the ownership and operation of the Assets which are paid by Seller and incurred during the Adjustment Period, except, in each case (i) any Property Costs and other such costs already deducted in the determination of proceeds in Section  3.2(a) and (ii) any Asset Taxes, Income Taxes and Transfer Taxes;

(e)    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;

Similarly, the adjustment described in Section  3.2(d) 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.

Section 3.3    Allocation of Purchase Price . The Allocated Values assigned to the Assets are set forth in Schedule 3.3 .

20

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.

21

Encumbrances and the terms and provisions of the Contracts, the Surface Contracts and the Conveyance, that:

Notwithstanding the foregoing, the following shall not be considered Title Defects provided that Seller’s revenues related to any Well or Assigned Wellbore are not currently being held in suspense related to any such matters:

(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;

22

(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; and

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 Lease, Unit, Prospect, Well or Assigned Wellbore shown on the Asset Exhibits, without causing a greater than proportionate increase in Seller’s working interest above that shown in the Asset Exhibits as of the Effective Time.

(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 below that shown in the Asset Exhibits or (ii) increase Seller’s working interest above that shown in the Asset Exhibits without a proportionate increase in the Net Revenue Interest;

(b)    All Leases and all Contracts listed in Schedules 2.2(a)(iv) and 2.2(a)(v) , to the extent that they do not, individually or in the aggregate, (i) reduce Seller’s Net Revenue Interest below that shown in the Asset Exhibits or (ii) increase Seller’s working interest above that shown in the Asset Exhibits without a proportionate increase in the Net Revenue Interest;

(c)    Preference Rights applicable to this or any future transaction; provided, that such Preference Rights are subject in all respects to Section  8.6 of this Agreement;

Section 4.4    Notice of Title Defect Adjustments.

(a)    To assert a claim of a Title Defect prior to Closing, Purchaser must deliver a claim notice to Seller (each a “ Title Defect Notice ”) on or before seven (7) calendar days prior to the Closing Date (as such date may be adjusted in accordance with the terms of this Agreement) at 5:00 p.m. Central Time (the “ Title Claim Date ”). To be effective, each Title Defect Notice shall be in writing and shall include (i) a description of the alleged Title Defect(s), (ii) the Leases, Units, Prospects, Wells or Assigned Wellbores affected by the Title Defect (each a “ Title Defect Property ”), (iii) the Allocated Value of each Title Defect Property, (iv) to the

24

extent available, supporting documents reasonably necessary for Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of and extent of the alleged Title Defect(s) and the amount by which the Allocated Value of each Title Defect Property is reduced by the alleged Title Defect(s), and (v) the amount by which Purchaser reasonably believes the Allocated Value of each Title Defect Property is reduced by the alleged Title Defect(s) and the computations and information upon which Purchaser’s belief is based. NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT TO THE CONTRARY, PURCHASER SHALL BE DEEMED TO HAVE WAIVED ITS RIGHT TO ASSERT TITLE DEFECTS OF WHICH SELLER HAS NOT BEEN GIVEN NOTICE MEETING THE REQUIREMENTS OF THIS SECTION  4.4 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 Lease, Unit, Prospect, Well or Assigned Wellbore 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 Leases, Units, Prospects, Wells or Assigned Wellbores affected, (iii) the Allocated Values of the Leases, Units, Prospects, Wells or Assigned Wellbores in the Asset Exhibits subject to such Title Benefit, and (iv) the amount by which Seller reasonably believes the Allocated Value of those Leases, Units, Prospects, Wells or Assigned Wellbores 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 to have one of the following remedies apply:

(i)    subject to the Defect Threshold, 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

25

(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 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 date that the Title Defect is cured, 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. 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 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 Asset in the Asset Exhibits affected by Title Benefits reported under Section  4.4(b) , subject to the amount of the aggregate Title Benefits (the “ Title Benefit Amount ”), such Title Benefit Amount 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;

26

(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 the Asset Exhibits 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 the Asset Exhibits;

(iv)    if the Title Defect results from Sellers owning fewer Net Mineral Acres in such Title Defect Property than the Net Mineral Acres specified therefor in the Asset Exhibits, 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 Net Mineral Acres and the denominator of which is the number of Net Mineral Acres specified for such Title Defect Property in the Asset Exhibits;

(v)    if the Title Defect results from any matter not described in subsections (i), (ii) (iii) or (iv) 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

(vi)    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.

27

(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 Lease, Unit, Prospect, Well or Assigned Wellbore, the amount by which the value of the affected Lease, Unit, Prospect, Well or Assigned Wellbore is enhanced by virtue of (A) Seller having a greater Net Revenue Interest or greater number of Net Mineral Acres in such Lease, Unit, Prospect, Well or Assigned Wellbore than the Net Revenue Interest or Net Mineral Acres specified therefor in the Asset Exhibits, (B) Seller having a lesser working interest in such Lease, Unit, Prospect, Well or Assigned Wellbore than the working interest specified therefor in the Asset Exhibits, or (C) such Lease, Unit, Prospect, Well or Assigned Wellbore 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 Lease, Unit, Prospect, Well or Assigned Wellbore 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 Lease, Unit, Prospect, Well or Assigned Wellbore, the Title Benefit Amount with respect to such affected Lease, Unit, Prospect, Well or Assigned Wellbore shall be determined in the manner provided in Section  4.4(g) .

(iii)    If the Title Benefit Amount results from Seller having a greater Net Revenue Interest (without a corresponding increase in working interest) or greater number of Net Mineral Acres in such Lease, Unit, Prospect, Well or Assigned Wellbore than the Net Revenue Interest or Net Mineral Acres specified therefor in the Asset Exhibits, the Title Benefit Amount shall be equal to the product obtained by multiplying the Allocated Value of such Lease, Unit, Prospect, Well or Assigned Wellbore by a fraction, the numerator of which is the increase in the Net Revenue Interest or Net Mineral Acres, as applicable, and the denominator of which is the Net Revenue Interest or Net Mineral Acres, as applicable, specified for such Lease, Unit, Prospect, Well or Assigned Wellbore in the Asset Exhibits.

(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 all Title Defect Amounts and Title Benefit Amounts prior to Closing. If Seller and Purchaser are unable to agree by Closing, the Title Defect Amounts and Title Benefit Amounts in dispute 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, as selected by mutual agreement of Purchaser and Seller within fifteen (15) Business Days after the end of the Cure Period (the “ Title Expert ”). The Title Expert’s determination shall be made within fifteen (15) Business

28

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) and Section  4.4(h) and may consider such other matters as in the opinion of the Title Expert are necessary or helpful to make 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 shall act as an expert for the limited purpose of determining the specific disputed Title Defect Amounts and Title Benefit Amounts 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 Title Defect Amount or a Title Benefit Amount, (i) Purchaser shall pay to Seller the amount, if any, so awarded by the Title Expert to Seller, plus interest payable on such amount at the Agreed Interest Rate from (but not including) the Closing Date to (and including) the date on which such amount is paid to Seller and (ii) Seller shall pay to Purchaser the amount, if any, so awarded by the Title Expert to Purchaser.

(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 unless the aggregate Title Defect Amount and Environmental Defect Amount exceeds an amount equal to three percent (3%) of the Total Allocated Value (the “ Defect Threshold ”), after which point adjustments to the Cash Consideration or other remedies shall be made or available to Purchaser from the first dollar of uncured Title Defects and uncured Environmental Defects.

Section 4.5    Casualty or Condemnation Loss.

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 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 (a) 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 (b) 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, VIOLATION OF A LEGAL REQUIREMENT OF SELLER.

29

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 Claim 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 and federal 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 or state 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 or state agencies, as applicable, of Seller’s assignment documents requiring federal or state approval in order for Purchaser to be recognized by the federal or state agencies as the owner of the Assets. Purchaser shall provide Seller with approved copies of the assignment documents and other state and federal 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;

(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

30

(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) with respect to any Assets where 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 American Society for Testing and Material Standard Practice Designation E1527-05, then Purchaser may request Seller’s consent to conduct additional Phase II environmental property assessments or such other activities intended to constitute the conduct of “all appropriate inquiries” under 30 CFR Part 312 (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

31

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 seven (7) days prior to the Closing Date at 5:00 p.m. Central Time (the “ Environmental Claim Date ”), Purchaser may notify Seller in writing of such Environmental Defect (an “ Environmental 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 (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 Seller disagrees with any of Purchaser’s assertions with respect to the existence of an Environmental Defect or the

32

Environmental Defect Amount, Purchaser and Seller will attempt to resolve the dispute prior to Closing. 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 ”). 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. In the event the parties have failed to resolve any dispute regarding an Environmental Defect at Closing, Seller shall retain the Asset affected by the Environmental Defect, in which event the Cash Consideration shall be reduced by an amount equal to the Allocated Value of such Asset. Thereafter, the Independent Expert shall render his 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 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 that the Independent Expert delivers written notice to Purchaser and Seller of his 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) in no event shall there be any adjustments to the Cash Consideration for any uncured Environmental Defect unless the aggregate Environmental Defect Amount attributable to all such Environmental Defects, taken together with the aggregate Title Defect Amounts attributable to all uncured Title Defects, exceeds the Defect Threshold, after which point adjustments to the Cash Consideration or other remedies shall be made or available to Purchaser from the first dollar of uncured Title Defects and uncured Environmental Defects. 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.

33

(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.

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. The indemnity obligation set forth in this Section  5.4 shall survive the Closing or termination of this Agreement.
