VI. DEFENSIBLE TITLE.

     A. Defensible Title and Title Defects. For the purpose of this Agreement, “Defensible Title” shall mean title to the Leases reflected in the real property records of the county and, if applicable, in the records of the appropriate governmental agency, that (i) entitles Purchaser to receive operating rights to the net mineral acres to be conveyed at Closing as set forth in the Title Letter and (ii) is free and clear of encumbrances, liens, unsatisfied judgments and defects which negatively impact Purchaser’s ability to enter upon the real property subject to the Leases for purposes of drilling any wells and/or transporting oil and gas within any portion of the Lease Block Area, or which negatively effects Purchaser’s entitlement set forth in (i) of this Section. Any Leases which do not meet the standards of “Defensible Title” shall be deemed to have a “Title Defect”.

      B. Purchase Price Calculation.

	1.		Title Notice. Purchaser shall give Seller a written “Title Letter” as soon as reasonably possible but no later than three (3) days prior to the Closing Date at 5:00 p.m., MT. The Title Letter shall state the number of net mineral acres for which Purchaser has confirmed that Seller has Defensible Title (the “Defensible Title Acres”), and shall also list the Leases covering said acres (collectively, the “Defensible Title Leases”). At the Closing, Purchaser shall purchase a seventy-five percent (75%) interest in the Defensible Title Leases. The Title Letter shall also contain a calculation of the Purchase Price to be paid by Purchaser which shall be equal to the number of Defensible Title Acres, multiplied by Twenty-Two Dollars and 22/100 ($22.22), which amount shall then be multiplied by seventy-five percent (75%). With respect to the net mineral acres on which Purchaser has not confirmed that Seller has Defensible Title, Seller shall diligently attempt to cure same to Defensible Title standards on or before sixty (60) days after the Closing Date, and Purchaser shall subsequently have the option to acquire same, as and when cured, pursuant to the acquisition terms set forth in this Agreement. If Seller is unable to cure the defects within sixty (60) days from the Closing Date, said Leases shall be owned by Seller and not subject to this Agreement.
	2.		Seller has represented that it has Defensible Title to 150,000 net mineral acres within the Lease Block Area. In the event that the number of Defensible Title Acres, as set forth in the Title Letter, comprise less than one hundred one hundred twenty thousand (120,000) net acres, Purchaser, in its sole discretion, may elect to terminate this Agreement. In such event Purchaser shall so notify Seller in writing and the Initial Deposit and the Second Deposit (if applicable) shall be immediately returned to Purchaser, and both parties shall be released from any duties or obligations, each to the other, with respect to the transaction contemplated by this Agreement.

     C. Permitted Encumbrances. The following shall not be considered Title Defects

hereunder (collectively the “Permitted Encumbrances”):

	1.		Liens for current taxes or assessments not yet due or delinquent on the Closing or, if delinquent, that are being contested in the ordinary course of business;
	2.		Materialmen’s, mechanic’s, repairman’s, employee’s, contractor’s, operator’s and other similar liens or charges arising in the ordinary course of business, for amounts not yet delinquent; and
	3.		All rights to consent by, required notices to, filings with or other actions by governmental authorities in connection with the sale or conveyance of oil and gas leases or interests therein or sale of production therefrom if the same are customarily obtained subsequent to such sale or conveyance.

VII. CONDITIONS OF CLOSING.

     Purchaser’s obligation to consummate the transaction contemplated by this Agreement is subject to the satisfaction or waiver by Purchaser of all of the following conditions:

     A. Representations. The representations contained in Article V hereof shall be true and correct in all material respects on the Closing Date as though made on and as of the Closing Date.

     B. Performance. Seller shall have performed in all material respects the obligations, covenants and agreements hereunder to be performed by it at or prior to the Closing Date.

     C. Pending Matters. No suit, action or other proceeding by a third party or a governmental authority shall be pending which seeks damages, fines or other penalties from either party in connection with the Leases or the Lease Block Area, or seeks to restrain, enjoin or otherwise prohibit the consummation of the transactions contemplated by this Agreement.

     D. Joint Venture Agreement. The parties shall have entered into a Joint Venture Agreement to develop oil and gas wells within the Lease Block Area upon terms and conditions mutually agreeable to the parties. The Joint Venture Agreement shall provide that all costs and net profits from the Joint Venture shall be divided seventy-five percent (75%) to Purchaser and twenty-five percent (25%) to Seller and/or its assigns. Purchaser shall be the operator of the Joint Venture and shall have the right to determine the well locations, provided, however, that Seller shall have the right to “opt out” of any particular well prior to drilling, in which case Seller shall not participate in the costs or profits generated from said well and further provided that once Seller “opts out” of a specific well, Seller shall be prohibited from participating in any other well drilled within a six hundred forty (640) acre block surrounding the original “opt out” well. The Joint Venture Agreement shall also include a right of first refusal in favor of Purchaser in the event that Seller wishes to transfer its retained interest in the Leases or the Joint Venture, and Purchaser shall have ten (10) days from receipt of the offer to purchase Seller’s

interest, provided, however, that this right of right of first refusal shall not apply to any transfer which (i) takes place within thirty (30) days of the Closing Date, and (ii) transfers one-half (¹/2 ) or less of Seller’s retained interest in the Leases or the Joint Venture.

All ad valorem taxes, real property taxes, personal property taxes and similar obligations with respect to the Defensible Title Leases for the tax period in which the Closing Date occurs shall be prorated as of the Closing Date between Seller and Purchaser, taking into account the fact that Seller is retaining a Twenty-Five Percent (25%) interest in the Leases. The portion of such apportioned tax liability which is attributable to the Seller shall be credited to Purchaser as an adjustment of the Purchase Price and each party shall file or cause to be filed all required reports and returns incident to its share of such taxes and shall pay or cause to be paid to the taxing authorities all such taxes arising out of the tax period in which the Closing Date occurs.

     B. Proration of Other Taxes, Etc.
