        Southwest 36th Street, Oklahoma City, OK, 73179, Attn: Mr. Kirk Woford,

        September 21, 2004. Seller at its expense will deliver the Aircraft to
        Duncan Aviation, Lincoln, NE. The Prepurchase Inspection shall be at

        Pre-purchase Inspection, including but not limited to engine boroscope,
        windshield thickness check, under potty area check for corrosion, fuel

        at the sole discretion of the Purchaser. Purchaser shall advise both
        Seller and Escrow Agent of the results of the Prepurchase Inspection
        within 24 hours after its completion. The Prepurchase Inspection
        facility shall provide Purchaser with a list of discrepancies noted. The
        Purchaser and its representative reserve the right to perform a Post
        Prepurchase Inspection Test Flight (PPITF) if the Prepurchase Inspection
        Facility determines that a discrepancy or multiple discrepancies noted
        during the Prepurchase Inspection warrant that a PPITF be performed. If
        the PPITF is performed, it is not to exceed two hours in duration, and
        the cost of the fuel and MSP expenses are to be paid by the Purchaser.
        Aircraft shall remain in the care and custody and be flown by the
        Seller's pilot (as PIC) during the PPITF. Purchaser and Seller shall
        execute Exhibit B, Notification of Results of Aircraft Prepurchase
        Inspection, on the later of (i) within 24 hours following the completion
        of the Prepurchase Inspection and (ii) October 1, 2004.

               (a) Rejection. Upon receipt of notification from Purchaser that
        the Prepurchase Inspection has been completed and that the Aircraft has
        been rejected, Seller shall cause the Escrow Agent to immediately
        refund, in full, the deposit to Purchaser (minus fuel and MSP expense
        incurred by Seller to return the aircraft to its base airport in Sioux
        City, IA), and this Agreement will be terminated.





               (b) Acceptance. Upon receipt by the Escrow Agent of notification
        from Purchaser that the Prepurchase Inspection has been completed and
        that the Aircraft has been accepted, subject to Seller at its expense
        repairing the discrepancies noted, Purchaser and Seller shall execute
        Exhibit B, Aircraft Acceptance/Rejection Form, the deposit will become
        non refundable, except as provided herein, and should Purchaser
        thereafter fail to complete the purchase, unless such failure is the
        result of Seller's failure to perform or the breach of Seller's
        obligations or warranties, the Seller shall be entitled to receive the
        escrow deposit as its sole and exclusive remedy as liquidated damages in
        satisfaction of any and all claims and in lieu of any other damages or
        remedies. The aggregate cost of correcting the discrepancies set forth
        in Exhibit B shall reduce the Purchase Price by the amount of such cost.

5.      The Purchaser and its representative shall be permitted to perform a
        Post Prepurchase Inspection Test Flight, if required, as per Paragraph 4
        above, not to exceed two hours in duration, upon the conclusion of the
        Prepurchase Inspection and the repair of noted discrepancies, to
        determine that the Aircraft conforms to the delivery requirements per
        Paragraph 6 below. Seller shall correct, at Seller's sole expense, any
        airworthiness discrepancies which may be noted during the PPITF prior to
        closing and delivery to Purchaser. The cost of the fuel and MSP expenses
        are to be paid by the Purchaser. Aircraft shall remain in the care and
        custody and be flown by the Seller's pilot (as PIC) during the PPITF.
        SIC must meet open pilot warranty of Sellers Insurance Co.

6.      The Aircraft will be delivered free and clear of all security interests,
        liens or encumbrances of any nature whatsoever to Purchaser in Lincoln,
        Nebraska, with a US FAA Certificate of Airworthiness, in an airworthy
        condition, with: all systems operating normally and meeting
        manufacturers specifications; no damage history or corrosion history

        time and calendar actions completed through closing without deferment or
        extension, or increased frequency of any inspections, whether cycles,
        calendar, or hours; and recommendations thereof.

7.      The Closing and Delivery shall be set to occur no later than 2 business
        days after the Aircraft has been returned to service as per this
        agreement, and the Purchaser has conducted the PPITF, if required, as

        final payment in full for the Aircraft in the amount of $4,700,000.00
        US. Dollars. Delivery shall take place as evidenced by executing
        Appendix 1, Aircraft Delivery Receipt, and being sent via facsimile to
        IATS, IATS will then proceed to simultaneously file the Bill of Sale and
        Lien release with the FAA Registry on behalf of Purchaser, and wire
        transfer the Purchase Price to Seller, per their written instructions,
        and send Purchaser via overnight mail the Warranty Bill of Sale.

8.      With Seller's full and complete compliance with the terms and conditions
        contained herein and with written notification that the Aircraft is
        ready for delivery, should the Purchaser fail to close for any reason
        other than provided for herein, then, Seller may retain the deposit of

        Aircraft, that it has good and merchantable title to the Aircraft, and
        that the Aircraft upon delivery will be free and clear of all security

        which shall be deemed an original and shall be effective when executed
        by both parties.

23.     This contract shall be deemed to have been made, executed under and
        governed by the law of the State of Nebraska, USA.

24.     Seller and/or Purchaser may structure the transaction herein

        like-kind exchange under the provisions of Section 1031 of the Internal
        Revenue Code of 1986, as amended, and the Treasury Regulations
        promulgated thereunder (the "Regulations"). It is expressly acknowledged
        that Seller and/or Purchaser may assign its rights in this AGREEMENT to
        a qualified intermediary as defined in the Regulations ("Qualified
        Intermediary") and at Closing, at the request of Purchaser or the
        Qualified Intermediary, Seller will transfer title to the Aircraft to
        Purchaser, the Qualified Intermediary or to an "Exchange Accommodation
        Titleholder" as defined in Revenue Procedure 2000-37, 2000-2 C.B. 38.
        Any assignment of this AGREEMENT shall be in writing and notification of
        the assignment shall be given to Seller and/or Purchaser in writing at
        or before Closing. Seller and/or Purchaser will cooperate with Seller
        and/or Purchaser if requested by Seller and/or Purchaser to structure
        the transaction in such manner, and will execute any documents that
        Seller and/or Purchaser may be reasonably requested to sign that are
        consistent with this AGREEMENT, provided Seller and/or Purchaser incurs
        no additional cost or expense and is held harmless against any liability
        arising because of the intended like-kind exchange or any challenge to
        or failure of this transaction to qualify for such treatment. The
        conclusion of such like-kind exchange shall not be a condition precedent
        to the conclusion of this AGREEMENT, the acceptance of the Aircraft or
        payment for the Aircraft.

                                       4
