TITLE MATTERS. 5.1 Definitions. (a) The term "Defensible Title" shall mean, as to the Leasehold Interests, such title held by Seller that (i) is free from reasonable doubt to the end that a prudent purchaser engaged in the business of the ownership, development and operation of producing oil and gas properties, with knowledge of all of the facts and their legal bearing, would be willing to accept and pay full value therefor; (ii) is deducible of record from the records of the applicable parish or county, or, in the case of federal leases, from the records of the applicable office of the Bureau of Lands Management or Minerals Management Service, or, in the case of state leases, from the applicable records of the applicable state land office; (iii) entitles Buyer, as Seller's successor in title, to receive not less than the "Net Revenue Interest" set forth in EXHIBIT A-II as to each Leasehold Interest, without reduction, suspension or termination throughout the productive life of such Leasehold Interest; (iii) obligates Buyer, as Seller's successor in title, to bear costs and expenses relating to operations on and the maintenance and development of each Leasehold Interest in an amount not greater than the "Working Interest" set forth in EXHIBIT A-II with respect to each Leasehold Interest; without increase for the respective productive life of such Leasehold Interest, and (iv) is free and clear of liens and material encumbrances and defects, except for Permitted Encumbrances. (b) The term "Permitted Encumbrances," as used herein, shall mean the following, provided that, as to Leasehold Interests, the net cumulative effect of such encumbrances does not operate to reduce the Net Revenue Interest as to any Leasehold Interest to less than the Net Revenue Interest set forth in EXHIBIT A-II for such Leasehold Interest and does not operate to increase the costs and expenses relating to the operations on and the maintenance and development of any Leasehold Interest in an amount greater than the Working Interest set forth in EXHIBIT A-II for such Leasehold Interest: (1) lessors' royalties, overriding royalties, unitization and pooling designations and agreements, reversionary interests and similar burdens (to the extent same are a matter of public record in the records of the applicable parish or county, the records of the applicable office of the Bureau of Lands Management or the Minerals Management Service or the applicable records of the applicable state land office); (2) required third party consents to assignments and similar agreements with respect to which (i) waivers or consents are obtained from the appropriate parties prior to the Closing Date, or (ii) the appropriate time period for asserting such rights has expired prior to the Closing Date without an exercise of such rights; 16 18 (3) all rights to consent by, required notices to, filings with, or other actions by governmental entities in connection with this Acquisition if the same are customarily obtained subsequent to such sale or conveyance; (4) easements, rights-of-way, servitudes, permits, surface leases and other rights with respect to surface operations, pipelines, canals, ditches, reservoirs or the like; conditions, covenants or other restrictions; and easements for pipelines, telephone lines, power lines and other easements and rights-of-way, on, over or in respect of any of the Interests which are owned by third parties and do not materially affect the value of the Interests or operations thereon; (5) the Contracts; (6) liens for taxes not yet delinquent or, if delinquent, being contested in good faith; (7) undetermined or inchoate liens or charges incurred or threatened incidental to maintaining, developing, producing, processing or operating the Interests of which Seller has no notice prior to the Closing Date; and (8) materialman's, mechanics', repairman's, employees', contractors', operators' or similar liens, security interests or charges that are not delinquent or, if delinquent, are being contested in good faith. (c) The term "Title Defect" as used herein shall mean any material encumbrance, encroachment, irregularity, defect in or objection to title to the Interests (expressly excluding Permitted Encumbrances), that alone or in combination with other Title Defects renders title to the Leasehold Interests less than Defensible Title. Additionally, the term Title Defect includes the following: (1) If Buyer determines reasonably and in good faith that there has been substantial non-compliance with the material laws, rules, regulations, ordinances or orders of any governmental agency or authority having jurisdiction over the Leasehold Interests, resulting in substantial risk of loss of the Leasehold Interests or value thereof, then Buyer may elect to treat such non-compliance as a Title Defect. (2) If Seller is obligated by virtue of a prepayment arrangement under any contract or other arrangement to deliver Hydrocarbons produced from the Leasehold Interests at some future time without then or thereafter receiving full payment therefor, then Buyer may elect to treat such arrangement as a Title Defect. (3) If Buyer becomes aware of any suit, action or other proceeding before any court or governmental agency that Buyer determines reasonably and in good faith would result in loss or impairment of Seller's title to any portion of the Leasehold Interests or a portion of the value thereof, Buyer may elect to treat such action as a Title Defect. 17 19 (4) If any necessary third party consent to assignment of any of the Leasehold Interests is not obtained prior to the Closing Date, Buyer may elect to treat such consent requirement as a Title Defect.

(a) A Title Defect shall not be considered for adjustment unless such Title Defect results, in Buyer's good faith and reasonable calculation, in a reduction in the Allocated Value of a Leasehold Interest in excess of $25,000.00. "Allocated Value" of a Leasehold Interest, as used in this Agreement, means the value allocated to each Leasehold Interest as set forth in EXHIBIT A-II hereto.

Buyer shall be deemed to have waived all Title Defects of which Seller has not been given timely notice by Buyer.

If by such date the Seller has cured the Title Defect to Buyer's reasonable satisfaction, in the case of a Leasehold Interest that was excluded, the Buyer shall be required to purchase the Leasehold Interest and pay Seller the amount by which the Purchase Price was reduced as a result of the exclusion of the Leasehold Interest and, in the case of the reduction of the Purchase Price in accordance with Section 5.2(c)(iv), the Buyer shall be required to pay to the Seller the amount by which the Purchase Price was reduced on account of the Title Defect.

At the Closing, Seller shall pay to Buyer all sums paid to Seller by third parties (including insurance claims) by reason of the destruction or taking of such Interests to be assigned to Buyer, and shall assign, transfer and set over unto Buyer all of the right, title and interest of Seller in and to any unpaid awards or other payments from third parties (including insurance companies) arising out of the destruction, taking or pending or threatened taking as to such Interests to be conveyed to Buyer. Seller shall not voluntarily compromise, settle or adjust any material amounts payable by reason of any destruction, taking, pending or threatened taking as to the Interests to be conveyed to Buyer without first obtaining the written consent of Buyer. 6.

For the purpose of this Section, an Environmental Condition or Violation of Environmental Laws shall be "material" only if the cost to remediate a condition of an Interest or the fine or penalty associated with the same is, or is reasonably expected to be, in excess of $50,000.00. Buyer shall treat all information regarding any adverse Environmental Conditions and Violation of Environmental Law as confidential whether material or not and shall not make any contact with any governmental authority regarding the same without Seller's written consent prior to the Closing Date except as required by law except as Buyer may be required or desire as an owner and/or operator of the Interests. 6.2 Environmental Defect Adjustments.
