1. Promise to
Pay. FOR VALUE RECEIVED, the undersigned (hereinafter referred to as Debtor) hereby absolutely and unconditionally promises to pay to the order of Raytheon Aircraft Credit Corporation, at 101 S. Webb Street, Suite 300, Wichita,
Kansas 67207 (together with its successor and assigns, hereinafter referred to as RACC), in lawful money of the United States of America and in immediately available funds, the principal sum of TWO MILLION ONE HUNDRED SIXTEEN THOUSAND
FIVE HUNDRED SEVENTY THREE AND 70/100 DOLLARS ($2,116,573.70), together with interest on the principal amount outstanding hereunder from the date hereof as specified below, until paid in full. All payments made pursuant to this Promissory Note will
be made free and clear of, and without deduction for, withholding, setoff, recoupment or counterclaim of any kind.

2. Rate of Interest; Late Payment
Charge. Debtor agrees to pay to RACC interest on the unpaid principal balance hereunder, as follows:



| | A. | The rate of interest of this Promissory Note shall be six and three-quarters percent (6.75%) per annum.
| | -- | -------------------------------------------------------------------------------------------------------



| | B. | Notwithstanding the foregoing Clause A, while an Event of Default (as defined in Section 12) is continuing, the principal outstanding hereunder and, to the extent permitted by
applicable law, any overdue interest or other amounts payable hereunder shall bear interest (compounded monthly and payable on demand in respect of overdue amounts) at the rate of ten percent (10%) per annum until such Event of Default has been
cured or waived in writing by RACC (after as well as before judgment).
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

All interest shall be calculated on the basis of a 360-day year and
actual days outstanding. Notwithstanding anything set forth in this Promissory Note to the contrary, in no event shall the rate of interest payable pursuant to this Section 2 be higher than the maximum amount permitted under applicable law.

3. Payment Schedule. Payment of the principal balance together with accrued interest shall be made in monthly installments payable in arrears. The
first installment payment shall be due and payable to RACC on March 30, 2007. Each subsequent installment payment shall be due and payable to RACC on the 30th day of each month thereafter, until June 30, 2011, when the entire remaining
balance of principal and interest shall be paid in full. The amount of each installment payment will be as set forth on Schedule 1 hereto. Notwithstanding the foregoing, in the event of loss, theft, confiscation or substantial damage to the
Aircraft, Debtor shall pay all amounts owing under this Promissory Note within thirty (30) days following demand by RACC.

4. Taxes. All
payments (whether of principal, interest or otherwise) made by Debtor to RACC pursuant to this Promissory Note will be free and clear of and without deduction for any taxes, levies, duties, charges, fees or withholdings of any nature, provided,
however, that taxes based on the net income of RACC are specifically excluded from the provisions of this Section 4. If Debtor is required by law to make any such deduction or withholding, the sum due from Debtor will be increased to the extent
necessary to ensure that RACC receives a sum equal to what it would have received had no such deduction or withholding been required. Within thirty (30) days after Debtor has made any payment from which it is required by law to make any
deduction or withholding, Debtor will deliver to RACC a receipt issued by the applicable tax or other authority evidencing the deduction or withholding.

5. Prepayment. Subject to the provisions of Section 6 of the Amended and Restated Restructuring Agreement dated as of March 9, 2007 (as amended and in effect from time to time, the Restructuring Agreement)
between Debtor

and RACC, Debtor may prepay this obligation in part or in full at any time without any premium or penalty. Any partial prepayment shall be first applied to
accrued interest and then to the installments of principal in inverse order of maturity.

6. Disclaimer.If the Aircraft (as hereinafter defined)
does not operate as warranted, becomes obsolete, or the Aircraft is unsatisfactory for any reason whatsoever, Debtor shall make all claims on account thereof solely against RAC and not against RACC and Debtor shall nevertheless pay all sums payable
hereunder. Debtor acknowledges that neither RAC nor any sales representative or agent thereof, is an agent of RACC and no agreement or representation as to the Aircraft or any other matter by any such sales representative or agent of RAC shall in
any way affect Debtors obligations hereunder.

DEBTOR HAS SELECTED THE AIRCRAFT AND NEGOTIATED ALL DOCUMENTS RELATING TO THE PURCHASE THEREOF ALL

10. Purpose of Loan; Usury. The purpose of the [Amended and
Restated]Promissory Note dated as of December 31, 2002 issued by the Debtor to RACC (the Existing Note) was to [refinance] [finance]the Debtors acquisition of the Aircraft. This Promissory Note amends and restates
and has been issued in substitution as a replacement for the Existing Note. Nothing contained herein or in any other document shall be construed to constitute the payment or discharge of the Existing Note or to release or terminate any lien,
mortgage, pledge or other security interest in favor of RACC relating to the Existing Note. Debtor warrants and represents to RACC that this loan is for business and commercial purposes and not for personal, family, household or agricultural
purposes. It is agreed, notwithstanding any provision to the contrary in this Promissory Note or the Security Agreement, in no event will this Promissory Note or the Security Agreement require the payment of interest or charges in excess of the
maximum amount permitted by applicable law (the Maximum Rate) and the payment of obligations of Debtor under this Promissory Note and the Security Agreement are hereby limited accordingly. If under any circumstances, whether by reason of
advancement or acceleration of the maturity of the unpaid principal balance hereof or otherwise, the aggregate amounts paid on this Promissory Note or pursuant to the Security Agreement shall include amounts which by law are deemed interest and
would exceed the Maximum Rate, Debtor stipulates that payment and collection of such excess amounts shall have been and will be deemed to have been the result of a mistake on the part of both Debtor and RACC, and RACC shall promptly credit such
excess (to the extent only of such payments in excess of the Maximum Rate) against the unpaid principal balance hereof and any portion of such excess payments not capable of being so credited shall be refunded to Debtor.

11. Principals and Waivers. All signers, makers, guarantors, endorsers and sureties hereof are to be regarded as principals, jointly and severally. Every maker,
endorser, guarantor and surety hereof hereby waives presentment, demand for payment, notice of non-payment, notice of dishonor, and all other notices or demands in connection with the delivery, acceptance, performance, default or endorsement of this
Promissory Note, protest and impairment of collateral, as well as diligence in collecting this Promissory Note or enforcing any of the security therefor, and consents to all extensions, deferrals, partial payments and refinancings hereof before or
after maturity.
