NOW, THEREFORE, the parties hereto, with the intent to be legally bound, in return for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, including the mutual exchange of covenants and promises herein contained, agree as follows: ARTICLE I ACREAGE A. Simultaneous with the execution of this Agreement SKH shall assign, transfer and convey to Knox an undivided fifty percent (50%) interest in and to the existing Oil, Gas and Mineral Leases owned and held by SKH in the Prospects. The Oil, Gas and Mineral Leases which comprise approximately nine thousand (9,000) net mineral acres are more particularly identified on Exhibit "B"(the "Acreage') which is attached hereto and incorporated herein for all purposes. Excepting the warranties specifically set forth in other provisions of this Agreement, the Acreage acquired hereunder shall be conveyed to Knox by SKH with the following representations and warranties: (i) SKH shall unconditionally warrant and defend the title to the interest being herein assigned to Knox against any person or entity claiming the same, by, through, or under SKH, but not otherwise, (ii) that any and all oil, gas and mineral leases covering the Acreage shall be in full force and effect in accordance with the terms and conditions contained therein; (iii) SKH has full authority to execute and deliver the assignment provided for herein in order to convey to Knox the full interest in the Acreage which Knox contemplates hereunder; (iv) the net revenue interest assigned to Knox not be less than Knox's proportionate share of the actual net revenue interest which was delivered to SKH; and (vi) the Acreage shall be assigned to Knox free and clear of any mortgages, liens, burdens, or encumbrances, of any character or kind. The assignment, conveyance and bill of sale documents shall be in a form that is mutually agreeable to SKH and Knox. 1 B. As part of the ongoing exploration and development of the Livingston Area, SKH shall acquire additional Oil, Gas and Mineral Leases within the Clarkston and Lewisville Prospects. SKH has identified and anticipates the additional acquisition of three thousand (3,000) net mineral acres located within the Longview and Osborn Prospects ("Additional Acreage"). SKH will assign, transfer and convey to Knox its proportionate undivided fifty percent (50%) interest in the Additional Acreage promptly upon its acquisition by SKH, and shall in no event assign, transfer and convey the Additional Acreage within thirty (30) days of its acquisition by SKH. Knox agrees to pay all of the projected actual lease acquisition and brokerage costs as set forth on the Cost Allocation schedule which is attached hereto and incorporated herein as Exhibit "C." The projected lease acquisition and brokerage costs associated with the acquisition of the Additional Acreage is included within the amounts to be paid by Knox pursuant to the terms of Article III hereof. It is understood and agreed between the parties that the amounts set forth on the Cost Allocation are an estimate of the costs associated with the acquisition of the Additional Acreage and Knox agrees to pay all of the actual costs incurred to acquire the Additional Acreage in excess of the sums set forth on the Cost Allocation. In the event the actual costs to acquire the Additional Acreage are less than the costs set forth on the Cost Allocation, or SKH fails to acquire ten thousand (10,000) net mineral acres, SKH shall refund to Knox all excess funds. All Additional Acreage acquired hereunder shall be conveyed to Knox by SKH with the following representations and warranties: (i) SK shall unconditionally warrant and defend the title to the interest being herein assigned to Knox against any person or entity claiming the same, by, through, or under SKH, but not otherwise, (ii) that any and all oil, gas and mineral leases covering the Additional Acreage shall be in full force and effect in accordance with the terms and conditions contained therein; (iii) SKH has full authority to execute and deliver the assignment provided for herein in order to convey to Knox the full interest in the Additional Acreage which Knox contemplates hereunder; (iv) the net revenue interest assigned to Knox not be less than Knox's proportionate share of the actual net revenue interest which was delivered to SKH, and (vi) the Additional Acreage shall be assigned to Knox free and clear of any mortgages, liens, burdens, or encumbrances, of any character or kind. The assignment, conveyance and bill of sale documents shall be in a form that is agreeable to SK and Knox. C. SKH and Knox hereby establish an Area of Mutual Interest for each Prospect which is depicted on Exhibits B-1 and B-2 attached hereto. The term "Area of Mutual Interest" ("AMI") shall include all of the lands, oil, gas and mineral leasehold interests and personal property used or obtained in connection therewith and all oil, gas and mineral interests of every kind and nature within the lands described on Exhibit "A". The term AMI shall also include the oil, gas and mineral interests attributable to the lands outside such area which are required to be taken by lease, farmout or otherwise in order to get coverage on the oil, gas and mineral interests attributable to land described on Exhibit "A". The parties shall share the interests acquired within the AMI as follows: SKH - 50% Knox - 50% Either party making an acquisition ("Acquiring Party") shall give the other party written notice within ten (10) days of consummating such transaction of the terms of the transaction, including but not limited to, the type of interest 2 acquired, contract or lease terms, and the costs of acquisition. The party receiving such notice ("Reimbursing Party") shall have ten (10) days from the date of receipt to elect to acquire its proportionate share of such acquired interest. Failure to timely make an election to participate shall be deemed as an affirmative election not to participate in the acquisition. In order to exercise such election, the Reimbursing Party receiving notice shall tender to the Acquiring Party its proportionate share of the costs of such acquisition together with its written election to participate. Upon tendering such reimbursement, the Reimbursing Party shall be considered a proportionate owner of the interest so acquired and the Acquiring Party shall immediately execute, acknowledge and tender to the Reimbursing Party an assignment and/or conveyance of its proportionate interest. Each of the parties hereto agrees to assist the other in obtaining abstracts of title, title opinions, and other title data including title curative data. Each of the parties agrees to reimburse the other for its proportionate share of the costs of obtaining such data, curing title and brokerage fees as to any interests shared pursuant to the AMI. None of the other parties hereto shall be liable to the other in damages or otherwise for failure to perform under the terms hereof. The only consequence of such non-performance shall be the loss of all rights of the non-performing party hereunder except as to all interests within the AMI as to which such party has performed. The term of this AMI shall be for a period of ten (10) years and for as long thereafter as any lease subject to this agreement is held by production. D. In the event that the oil, gas and mineral leases covering the Prospects cover less than the full undivided mineral interest in the lands covered thereby, then the interest to be conveyed herein, shall be proportionately reduced in direct proportion to that which the mineral interests actually covered under said oil, gas and mineral leases. Such interest shall also be proportionately reduced in the event the oil, gas and mineral leases cover less than the full leasehold or mineral title, or in the event SKH did not acquire a full interest in the oil, gas and mineral leases. E. SKH shall provide to Knox, at SKH's sole cost and expense, copies of the oil, gas and mineral leases, title run sheets, title reports, title opinions, division orders, and any other documentation relating to the Prospects. ARTICLE II GEOPHYSICAL DATA SKH shall provide to Knox access to the workstation which houses the data, all associated well data, and any and all other geophysical information which SKH possesses within the Area of Mutual Interest, including but not limited to interpretations of existing seismic logs, cores, and production history. 3 ARTICLE III FUNDING Knox shall pay the sum of Four hundred seventy-five thousand dollars ($475,000.00) to SKH at closing. ARTICLE IV SALE OF INTEREST For a period of one (1) year following the execution of this Agreement, SKH and Knox mutually agree to cooperate in effecting the sale of the entirety of the leasehold acreage within the Livingston Transform Area , Longview, and Osborn prospects. ARTICLE V JOINT OPERATIONS All operations conducted in the Livingston Area shall be subjected to the provisions of a Joint Operating Agreement. All operations conducted on the Prospects shall be subject to the provisions of a Joint Operating Agreement. The Joint Operating Agreement shall be in the form and language of AAPL Form 610-1989, with the modifications and additions as set forth on Exhibit "E", attached hereto, including any further or additional modifications or amendments as may be mutually agreed by the parties ("JOA"). Knox shall be named as the Operator under the JOA. SK agrees to execute and deliver to Knox the JOA contemplated in this paragraph at Closing. In the event of a conflict between this Agreement and the terms of the JOA, this Agreement shall prevail. ARTICLE VI EXPLORATORY WELL A. SK and Knox agree that for a period of one (1) year from the date of execution of this Agreement neither party will propose the drilling of a well within the Prospects. B. After one (1) year from the date of the execution of this Agreement, either party may propose the drilling of an initial prospect exploratory well ("Initial Prospect Exploratory Well") within the Livingston Area for any Prospect Area (as hereinafter defined). Should any party desire to propose such Initial Prospect Exploratory Well ("Proposing Party"), said Proposing Party shall make the proposal in writing and provide the other party the following: (i) a structure map of the prospect to be tested at objective depths; (ii) an outline defining the Prospect Area. As a general rule, it is the intent of the parties that the Prospect Area outline shall be drawn on the nearest quarter section line outside the lowest closing contour of the structure rot be tested, or in the case of a stratigraphic trap or fault trap, the outline shall be drawn to the nearest quarter section lines outside the stratigraphic trapping boundary or the trapping fault plane. 4 (iii) an Authorization For Expenditure ("AFE") depicting both the cost for a dry hole and for a completed producing well. (v) a leasehold and ownership map covering the Prospect Area. The party receiving such notice ("Electing Party") shall have thirty (30) days following the receipt of all items set forth above in which to make its election to participate in the Initial Prospect Exploratory Well pursuant to the terms hereof. The JOA will govern the operations of the Initial Prospect Exploratory Well proposed for the Prospect Area, except to the extent it does not conflict wit the provisions of this Agreement, including, but not limited to the relinquishment provision set forth herein. Failure to timely make an election to participate shall be deemed as an affirmative election not to participate in the Initial Prospect Exploratory Well for a Prospect Area. A non-participating Party in the Initial Prospect Exploratory Well for any Prospect Area will relinquish its interest to the participating party as follows: (i) In the event the Initial Prospect Exploratory Well l is drilled to the objective formation and is capable of production in paying quantities, relinquish one hundred percent (100%) of its interest or right to earn or acquire an interest in the producing unit established for the Initial Prospect Exploratory Well, and relinquish fifty percent (50%) of its interest or right to earn or acquire a interest in the remainder of the Prospect Area to the participating Party. (i) In the event the Initial Prospect Exploratory Well is drilled to the objective formation and drilled as a dry hole, the amount of acreage relinquished to the participating Party as to the aforementioned one hundred percent (100%) interest will be limited to the applicable statewide or field spacing rules (for the field where the well is located) established by the Mississippi Oil & Gas Commission for the producing units for the objective formation as if the well had been completed as a producer. In the event the well is drilled to the objective formation and drilled as a dry hole then the relinquishment of the aforementioned fifty percent (50%) interest will still apply as to the balance of the Prospect Area. (i) In the event the participating Party while drilling in good faith, fails to reach the objective formation due to impenetrable substances or conditions in the hole which in a prudent operator's opinion would render further drilling impracticable but encounters producible hydrocarbons in a shallower formation, and should such Party desire to complete the well at such shallower formation it may elect to do so. In this case, should the completion attempt result in a productive well or a well capable of production in paying quantities, the non-participating Party will relinquish to the participating Party one hundred percent (100%) of its interest in the producing unit established for the well and relinquish fifty percent (50%) of its interest or right to earn or acquire a interest in the remainder of the Prospect Area to the participating Party. 5 C. All subsequent wells drilled in a Prospect Area shall be proposed by the parties in accordance with the JOA. All subsequent operations conducted on an Initial Prospect Exploratory Well and all subsequent wells shall be in accordance with the JOA. ARTICLE VII RELATIONSHIP OF PARTIES A.
