ARTICLE 3. TITLE MATTERS

Section 3.1 Seller’s Title.

(a) Seller represents and warrants to Buyer that Seller’s title to the Assets as of the Effective Time is Defensible Title (as defined below). The representation and warranty

in this Section 3.1 shall terminate as of the Closing and be replaced by the “Special Warranty” included in the Assignment.

(b) Other than as stated in Paragraph (a) immediately preceding, Buyer assumes risk of title and the condition of the Assets and will independently satisfy itself with respect thereto.

(c) Buyer will have until 5:00 P.M. Central Standard Time on the second (2) business day prior to Closing, to review title to the Assets and notify Seller in writing of any Title Defect(s) (as defined below) it discovers which render Seller’s title less than Defensible Title. Buyer shall use its best efforts, however, to keep Seller verbally advised of potential Title Defects, if any, as soon as they are discovered by Buyer.

(d) If Buyer properly notifies Seller of any such Title Defect, Seller shall have until 12:00 o’clock Noon Central Standard Time on the day following the date Buyer shall have provided notice under Paragraph (c) immediately preceding to review such claimed Title Defect and may, at its option, use reasonable efforts to cure the Title Defect within the same time period. If Seller declines or is unable to cure the Title Defect within such time period, Buyer shall have the option to either: (i) waive the Title Defect and proceed with Closing, or (ii) reduce the Purchase Price and proceed with Closing. The amount by which the Purchase Price will be reduced in the preceding sentence (“Title Defect Amount”) will be the value of such Title Defect, taking into consideration the allocated value of the specific Property or Asset 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 if such Title Defect is the result of a discovery by Buyer that Seller owned, as of the Effective Time, a Net Revenue Interest in a Property that is less than the Net Revenue Interest set forth on Exhibit A, then Purchaser and Seller agree that the proportion of reduction to the Purchase Price shall be equal to the product of the allocated value of such Property or Asset as set out on Exhibit G (“Allocated Value”) and the percentage reduction in such Net Revenue Interest as a result of such Title Defect. Provided further, however,that in the event the Title Defect Amount exceeds Ten Percent (10%) of the Purchase Price, either Buyer or Seller shall have the option, upon written notice to the other party prior to Closing, to terminate this transaction without any further liability.

(e) Net revenue interest not delivered by Seller at closing that is represented on Exhibit A will be treated as a Title Defect and result in a proportionate reduction in the Purchase Price.

(f) Buyer agrees to indemnify, defend and hold harmless Seller, its parent, subsidiary, affiliate corporations, directors, officers, employees, agents and representatives from and against any and all claims, causes of action, liabilities, damages, losses, costs and expenses (including, without limitation, court costs, expenses of litigation and reasonable attorney’s fees) in connection with personal injuries, including death or property damage arising out of or relating to the access of Buyer, its officers,

employees, and representative to such properties and to the records and other related information as permitted under this Agreement.

Section 3.2 Definition of Defensible Title. As used in this Agreement, the term “Defensible Title” means that title of Seller which, subject to Permitted Encumbrances:

(a) Entitles Seller to receive a share of the oil, gas and other associated minerals produced, saved and marketed from any unit or Well throughout the duration of the productive life of such Unit or Well (after satisfaction of all royalties, overriding royalties, nonparticipating royalties, net profits interests or other similar burdens on or measured by production of oil and gas) (“Net Revenue Interest”), of not less than the Net Revenue Interest share shown in Exhibit A for such unit or Well;

(b) Obligates Seller to bear a percentage of the costs and expenses for the maintenance and development of, and operations relating to, (i) any unit or Well not greater than the “working interest” shown in Exhibit A without increase throughout the productive life of such unit or Well except as stated in Exhibit A and except increases resulting from contribution requirements with respect to defaulting co-owners under applicable operating agreements and increases that are accompanied by at least a proportionate increase in Seller’s Net Revenue Interest;

(d) Is free and clear of liens, encumbrances, obligations, security interests, irregularities, pledges, gaps in title, or any Title Defects.

(e) As used in this Agreement, the term “Title Defect” means:

(i) any lien, charge, encumbrance, obligation (including contract obligation), defect, or other matter (including without limitation a discrepancy in Net Revenue Interest or working interest) that causes a breach of Seller’s representation and warranty in Section 3.1;

(ii) the subjection, subordination or imposition of any aspect of Seller’s ownership right in the Assets or any of them to or by a preferential right or consent to assign;

(iii) “Title Defect” does not include any liens discharged at the time of Closing.

(b) If, after the date of this Agreement but prior to Closing, any portion of the Assets is destroyed by fire or other casualty or is taken in condemnation or under right of eminent domain, at Buyer’s election, either (i) such casualty or taking shall be treated as a Title Defect with respect to the affected Property or Assets or (ii) the Purchase Price will not be adjusted, and Seller shall assign to Buyer all claims against third parties with respect

to such casualty, and in such event, Buyer shall take title to the Property affected by such loss without reduction of the Purchase Price.

ARTICLE 4. ENVIRONMENTAL MATTERS

Section 4.1 Assessment. Buyer may, at its option, cause an environmental assessment (“Assessment”) of all or any portion of the Assets to be conducted by a reputable environmental consulting or engineering firm (“Consultant”) selected by Buyer.

(i) waive the Environmental Defect and proceed with Closing; or

(ii) treat the affected property and rights subject thereto as an Excluded Asset and adjust the Purchase Price by the amount allocated to such property pursuant to Section 2.3 hereof. If the amount of such adjustment exceeds the sum of $100,000.00, either party may elect to terminate this transaction unless the other party shall agree to waive such Purchase Price adjustment.
