3.    LAWFUL MONEY.

      Principal and interest are payable in lawful money of the United States of
      America.

4.    DISBURSAL AND LOAN PURPOSE

      The Loan shall be disbursed according to Exhibit "A" on or about the dates
      provided therein to Borrower for the purpose of building the Simulator.
      These funds can be used for no other purpose.

5.    PAYMENTS

      Commencing on the first day of the month following the date of funding by
      Lender and continuing on the same day each month thereafter, Borrower
      shall make monthly installments of interest in the amounts as defined in
      Exhibit "A", and herein incorporated as part of this Note. Said
      installments shall not be subject to or limited to any source of funds of
      Borrower.

      On the Maturity Date, Borrower shall make a payment of the outstanding
      principal balance, all accrued interest and the Loan Fee. In addition,
      commencing on the Maturity Date and on the first day of each month
      thereafter, Borrower shall make sixty (60) equal monthly payments of the
      Revenue Participation Premium with the final payment of such Revenue
      Participation Premium due and payable on January 1, 2006.

      If any payment due hereunder is not received by Lender within five (5)
      days after its due date, then, in addition to the other rights and
      remedies of Lender, a per day late charge of Five Hundred Dollars
      ($500.00) will be charged to Borrower without notice. Such charge shall be
      immediately due and payable.

6.    PREPAYMENT.

      Borrower may, at any time within the Note term, prepay this Note
      (including the Loan Fee and the Revenue Participation Premium) in full or
      in part without incurring any premium or penalty. This Note is not
      considered paid in full until all principal, accrued interest, the Loan
      Fee, the Revenue Participation Premium, and any other amounts due
      hereunder have been paid in full. Borrower may prepay all or part of the
      Revenue Participation Premium by paying to Lender an amount equal to the
      present value of the Revenue Participation Premium at the time of
      prepayment; in calculating the present value, Borrower shall use a
      discount rate of seven percent (7%).

7.    SECURITY AGREEMENT.

      As security for the payment and performance of this Note, the Loan and all
      other present and future debts, obligations and liabilities of any nature
      whatsoever of any one or more of Borrower to Lender, and all
      modifications, renewals, replacements and extensions thereof (collectively
      the "Obligations"), Borrower hereby assigns to Lender and grants to Lender
      a first priority security interest in all of the Collateral subject only
      to the Permitted Exceptions. Borrower will execute any security
      agreements, collateral assignments, financing statements for filing and/or
      recording and any other lien writings required by Lender to evidence,
      create and perfect the liens and security interest of Lender. A carbon,
      photographic or other reproduced copy of this Note and/or any financing
      statement relating hereto shall be sufficient for filing and/or recording
      as a financing statement.

      Unless an Event of Default has occurred and is continuing, Lender's
      security interest in the Collateral will be released in full, except for
      its interest in Simulator accounts receivable, upon the Borrower's payment
      of (1) $2,500,000 plus interest at 12% per annum accrued but unpaid to
      Maturity Date and (2) the $250,000 Loan Fee. In addition, before or
      concurrent with a third party's purchase of any fractional ownership
      interest in the Simulator, Lender shall grant a release of such interest
      from the Collateral upon Borrower's repayment of a percentage of the
      Principal Amount and Loan fee that is equal to the percentage sold of the
      Simulator. For example, Borrower would repay 1/7th of the Principal Amount
      and Loan Fee if 1/7th fractional ownership interest in the Simulator was
      sold. Lender shall continue to maintain a first priority security interest
      in the accounts receivable generated by the sale of the fractional
      ownership interest in the Simulator until the Revenue Participation
      Premium is fully repaid.

      Borrower agrees that any and all funds received from its Initial Public
      Offering (the "IPO"), herein specified as the effective date of the IPO,
      shall be used to remove any senior liens on the motion and visual systems.

      Lender shall have no duty or obligation to protect, insure, collect or
      realize upon the Collateral or preserve rights in it against prior
      parties. Borrower releases Lender from, and shall indemnify Lender against
      any liability for any act or omission relating to the Collateral, except
      for any liability directly resulting from Lender's negligence or willful
      misconduct, as determined in a final non-appealable judgment.

      Borrower agrees as follows:

            (a)  Borrower (1) shall keep the Collateral free from all liens
                 other than the Permitted Exceptions, (2) shall defend the
                 Collateral against all claims and legal proceedings by persons
                 other than Lender, (3) shall pay and discharge when due all
                 taxes, levies and other charges upon the Collateral; (4) shall
                 not permit the Collateral to be used in violation of any policy
                 of insurance.

            (b)  Borrower shall pay all expenses and, upon Lender's request,
                 execute all writings and take all other actions reasonably
                 deemed advisable by Lender to preserve the Collateral or to
                 establish and determine priority of perfection, continued
                 perfection or enforce Lender's interest in the Collateral.

            (c)  Lender may examine and conduct audits of the Collateral and
                 Borrower's records concerning it, wherever located, and make
                 copies of such records, at any time during normal business
                 hours with two days advance notice, and Borrower shall assist
                 Lender in so doing. Borrower shall keep accurate complete and
                 current records respecting the Collateral.

For so long as the Note is secured by the Collateral, Borrower hereby makes,
constitutes and appoints Lender the true and lawful attorney-in-fact of
Borrower, in the name, place and stead of Borrower, other otherwise upon the
occurrence of any Event of Default until the default is cured as defined in
Section 16.

         (a)  To take all actions and to execute, acknowledge, obtain and
              deliver any and all writings necessary or deemed advisable by
              Lender in order to exercise any rights of Borrower with respect to
              the Collateral or to receive and enforce any payment or
              performance due to Borrower with respect to the Collateral;

         (b)  To give any notices, instructions or other communications to any
              Person or entity in connection with the Collateral;

         (c)  To demand and receive all performances due under or with respect
              to the Collateral and to take all lawful steps to enforce such
              performances and to compromise and settle any claim or cause of
              action of Borrower arising from or related to the Collateral and
              give acquittances and other discharges relating thereto; and

         (d)  To file any claim or proceeding or to take any other action, in
              the name of Lender, Borrower or otherwise, to enforce performances
              due under or related to the Collateral or to protect and preserve
              the right, title and interest of Lender thereunder.

The foregoing power of attorney is a power coupled with an interest and shall be
irrevocable and unaffected by the disability of the principal so long as the
Note is secured by the Collateral. Lender shall have no obligation to exercise
any of the foregoing rights and powers in any event.

      Borrower hereby grants and conveys to Lender, a non-exclusive,
      irrevocable, worldwide license to use Borrower's proprietary system
      software that Borrower has developed to run and operate the Simulator (the
      "System Software"), subject to the following:

                  (a)  Except in an Event of Default, Lender may not convey
                       this license or otherwise transfer its interest in,
                       or grant to any third parties any interest in or
                       right to use the System Software.

     Borrower shall indemnify and hold Lender, his successors and assigns,
     harmless from and against any claims of third parties, which assert that
     any of the System Software infringes a proprietary right of another party.

     This license agreement shall be governed by, interpreted and construed
     under, and enforceable in accordance with the laws of the State of
     Colorado.

      Borrower shall have no indemnification obligations for claims, actions or
      causes of action arising out of Lender's negligence or willful misconduct.

      received by Lender. Borrower shall not be liable for any settlement amount

      Agreement, including any and all statements and communications by the
      parties, their attorneys or representatives.

13.   SEVERABILITY.

      Should any of the terms of this Note and Agreement or its application to

      fullest extent permitted by law.

14.   BUSINESS RISK.

      Borrower and Lender (by its acceptance of this Note) hereby affirm, agree
      and acknowledge that because of the inherent business risk to Lender in
      the financing involved in this transaction, the Interest Rate, the Loan
      Fee and the Revenue Participation Premium provided in this Note constitute
      a fair and reasonable return to Lender in light of such business risk.

15.   INTEREST RATE LIMITATION.

      Borrower hereby agrees to pay an effective rate of interest that is the
      sum of the Interest Rate provided for herein, together with any additional

      Premium and any other fees to be paid by Borrower pursuant to the
      provisions of the Note. Lender and Borrower agree that none of the terms

      for the use, forbearance or detention of money requiring payment of
      interest at a rate in excess of the maximum interest rate permitted to be
      charged by the laws of the State of Arizona. In such event, if any holder
      of this Note shall collect monies which are deemed to constitute interest
      that would otherwise increase the effective interest rate on this Note to

      of the State of Arizona, all such sums deemed to constitute interest in
      excess of the such maximum rate shall, at the option of the holder, be

      returned to Borrower.
