FORM OF SECOND AMENDED AND RESTATED PROMISSORY NOTE

Raytheon Aircraft Credit Corporation

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 000 X. Xxxx Xxxxxx, Xxxxx 000, Xxxxxxx, Xxxxxx 00000 (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.

A-1

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 INDEPENDENTLY FROM RACC AND WITHOUT ANY PROMPTING, REFERRAL OR SUGGESTION FROM RACC. RACC HAS SOLELY PROVIDED A FINANCIAL ACCOMMODATION TO DEBTOR UNDER THIS NOTE AND HAS NOT ACTED AS AND SHALL NOT BE CONSTRUED TO HAVE ACTED AS ADVISOR, ARRANGER, PROMOTER OR GUARANTOR WITH RESPECT TO THE PURCHASE OF THE AIRCRAFT FROM RAC OR ANY ASPECT THEREOF.

7. Representations and Warranties. Debtor represents and warrants to RACC on the date hereof that:

(f) the execution, delivery, performance of its obligations, and exercise of its rights under this Promissory Note and the Security Agreement by Debtor, including borrowing under this Promissory Note, (i) do not require any permit, license or exemption from, approval, consent of, registration or filing with any local, state or federal governmental or regulatory agency or authority, required under applicable law, or with any other entity or person (each, a “Consent”); (ii) are not and will not be in conflict with or prohibited or prevented by any law, treaty, rule, regulation or determination of an arbitrator, court, or other governmental authority, in each case applicable to or binding upon Debtor or affecting any of its property (each a “Requirement of Law”); (iii) will not violate any of Debtor’s organizational documents or any judgment, order, law or regulation applicable to Debtor; and (iv) will not result in any breach of, or constitute a default under, or result in the creation of any lien, claim or encumbrance on any of Debtor’s property (except for liens in favor of RACC) pursuant to any indenture, mortgage, deed of trust, bank loan, credit agreement or other agreement or instrument to which Debtor is a party;

(d) cooperate with RACC, take such action, execute such documents, and provide such information as RACC may from time to time request in order further to effect the transactions contemplated by and the purposes of this Promissory Note and the Security Agreement.

9. Security Agreement. To secure the payment and performance of all of the obligations due RACC by Debtor under this Promissory Note and any renewals, extensions or changes hereof and of any and all other indebtedness of Debtor to RACC, either direct or indirect, absolute or contingent, whether now existing or hereafter arising, including all such obligations that would become due but for the operation of the automatic stay pursuant to §362(a) of the Federal Bankruptcy Code and the operation of §§502(b) and 506(b) of the Federal Bankruptcy Code and including, without limitation, post-petition interest, and including, without limitation, all “Obligations” as defined in the Restructuring Agreement (collectively, the “Obligations”), Debtor executed an Amended and Restated Security Agreement dated as of December 31, 2002, as amended by a First Amendment to Amended and Restated Security Agreement of even date herewith (as so amended and as may be further amended and in effect from time to time, the “Security Agreement”), granting RACC a security interest in the following described aircraft previously purchased by Debtor with the proceeds of the loan evidenced by this Promissory Note and the other property described below and in all additions and accessions thereto and substitutions and replacements thereof, all unearned insurance premiums and insurance proceeds and the proceeds of all of the foregoing (all of said property is hereinafter collectively referred to as the “Collateral”):

A. Raytheon Aircraft Company Aircraft Model 1900D, Serial Number             , Registration Number              (the “Aircraft”), together with all other property used in the operation of the Aircraft or reflecting use or maintenance of the Aircraft, including but not limited to all engines, propellers, instruments, avionics,

A-4

equipment and accessories attached to, connected with, located in or removed from the Aircraft and all logs, manuals and maintenance records.

Aircraft Engines: Make: Xxxxx & Xxxxxxx; Model: PT6A-67D; Shaft Horsepower: over 750; Serial Number (L):             ; Serial Number (R):             , together with any replacement engines.

Aircraft Propellers: Hub Make: Xxxxxxxx; Hub Model: HC-E4A-3; Hub Serial Number (L):             ; Hub Serial Number (R):             , together with any replacement propellers.

B. All contracts and agreements of every kind (oral and written), contract rights, rights to receive payments, goods or services of every kind, general intangibles, chattel paper and accounts, whether now existing or owned or hereafter arising or acquired, governing, relating to or arising out of Debtor’s right, title or interest in the Aircraft.

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 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.

A-5

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.

(l) an Event of Default as defined in the Restructuring Agreement shall occur;

THEN, or at any time thereafter:

(1) In the case of any Event of Default under clauses (g) or (h), the entire unpaid principal amount of this Promissory Note, all interest accrued and unpaid thereof, and all other amounts payable hereunder and under the Security Agreement, as well as any other indebtedness or liability of Debtor owed to RACC, shall automatically become forthwith due and payable, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived by Debtor; and

In addition to and without in any way limiting the foregoing, upon the occurrence of an Event of Default or at any time thereafter, RACC may employ all remedies allowed by law, including, without limitation, those available to a secured party under the Uniform Commercial Code. No remedy herein conferred upon RACC is intended to be exclusive of any other remedy and each and every remedy shall be cumulative and in addition to every other remedy hereunder, now or hereafter existing at law or in equity or otherwise.

A-7

13. Obligations Absolute. Debtor’s payment and performance obligations under this Promissory Note are absolute and unconditional. Any claim that Debtor may now or hereafter have against RACC or any affiliate thereof arising out of or in connection with the Aircraft, any of the other Collateral or any other matter shall not affect or excuse the unconditional obligation of Debtor to make any payment required to be made to RACC under this Promissory Note or the Security Agreement, and shall not be used or asserted as a defense to payment of such obligation or as set-off, counterclaim or deduction against such payment. RACC shall have no obligation or responsibility with respect to any dispute that may arise between Debtor and any such foregoing person, and no such dispute shall prevent RACC from taking such action as it may deem appropriate in order to preserve, protect or enforce its rights hereunder.

14. Debtor’s Agreement to Pay Enforcement Costs, etc. Debtor further agrees to pay to RACC, on demand, all costs and expenses (including court costs and legal expenses) incurred or expended by RACC in connection with the Obligations, this Promissory Note and the enforcement hereof, together with interest on amounts recoverable under this Section 14 from the time when such amounts become due until payment, whether before or after judgment, at the Default Interest Rate, provided that if such interest exceeds the maximum amount permitted to be paid under applicable law, then such interest shall be reduced to such maximum permitted amount.

17. GOVERNING LAW AND CHOICE OF FORUM.

THE PARTIES AGREE THAT ANY LEGAL PROCEEDING BASED UPON THE PROVISIONS OF THIS PROMISSORY NOTE SHALL BE BROUGHT EXCLUSIVELY IN EITHER THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF KANSAS AT WICHITA, KANSAS, OR IN THE EIGHTEENTH JUDICIAL DISTRICT COURT OF SEDGWICK COUNTY, KANSAS, TO THE EXCLUSION OF ALL OTHER COURTS AND TRIBUNALS.

Capitalized terms used and not otherwise defined herein shall have the meanings assigned to them in the Restructuring Agreement.

2. Promise to Pay. FOR VALUE RECEIVED, the undersigned hereby absolutely and unconditionally promises to pay to the order of RACC, at 000 X.

All payments made pursuant to this promissory note (this “Promissory Note”) will be made free and clear of, and without deduction for, withholding, setoff, recoupment or counterclaim of any kind.

3. Interest Rate. In addition to Debtor’s payment of the Principal Sum, Debtor shall pay interest to RACC on the outstanding Principal Sum at the rate of seven percent (7.00%) per annum. The annual rate of interest applicable hereunder from time to time, as specified above, is referred to herein as the “Interest Rate.” 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 3 be higher than the maximum amount permitted under applicable law.

4. Late Payment Charge. While an Event of Default (as defined below) is continuing, Debtor agrees to pay to RACC interest on the unpaid principal balance hereunder or other amounts payable hereunder (compounded monthly and payable on demand in respect of overdue amounts) at the rate of ten percent (10%) per annum (the “Default Interest Rate”) until such Event of Default has been cured or waived in writing by RACC (after as well as before judgment).

6. 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 6. 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.

7. Prepayment. This Promissory Note shall be subject to mandatory prepayment from Excess Cash as provided in Section 6(A) of the Restructuring Agreement.

8. Covenants. Debtor covenants and agrees that, until the payment and satisfaction in full of all the obligations of and amounts owed by Debtor under this Promissory Note, Debtor will:

(b) keep true and accurate books of account with respect to the Collateral and to permit RACC or its designated representatives to inspect the Collateral and the Aircraft and to examine and be advised as to such records upon the request of RACC;

(c) comply with any law, treaty, rule, regulation or determination of an arbitrator, court, or other governmental authority, in each case applicable to or binding upon Debtor or affecting any of its property;

(d) notify RACC promptly in writing of (i) the occurrence of any Default or Event of Default, (ii) any change of name or address of Debtor, (iii) any threatened or pending litigation or similar proceeding affecting Debtor or any material change in any such litigation or proceeding previously reported and (iv) any claims of any nature against the Collateral or the Aircraft; and

(e) cooperate with RACC, take such action, execute such documents, and provide such information as RACC may from time to time request in order further to effect the transactions contemplated by and the purposes of this Promissory Note and the other Transaction Documents.

C-2

9. Security Agreement. The payment and performance of all of the Obligations due RACC by Debtor under this Promissory Note, and any renewals, extensions or changes hereof, including all such Obligations that would become due but for the operation of the automatic stay pursuant to section 362(a) of the Federal Bankruptcy Code and the operation of sections 502(b) and 506(b) of the Federal Bankruptcy Code and including, without limitation, post-petition interest (collectively, the “Obligations”), shall be secured by the Corporate Security Documents, the Aircraft Security Agreements, the 120-071 Security Agreement, the Embraer Security Agreements, and any other collateral security now or hereafter granted to RACC by the Debtor.

10. Purpose of Loan; Usury. Debtor warrants and represents to RACC that this loan is for business and commercial purposes and not for personal, family, household or agricultural purposes. The purpose of this Promissory Note is to refinance the indebtedness outstanding under the Existing Senior Note and the Existing Subordinated Note. This Promissory Note has been issued in substitution as a replacement for the Existing Senior Note and the Existing Subordinated Note. Nothing contained herein or in any other document shall be construed to constitute the payment or discharge of the Existing Senior Note or the Existing Subordinated Note or to release or terminate any lien, mortgage, pledge or other security interest in favor of RACC relating to the Existing Senior Note or the Existing Subordinated Note. It is agreed, notwithstanding any provision to the contrary in any of the Transaction Documents, in no event will this Promissory Note 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 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 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. Waiver. The Debtor 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.

12. Events of Default; Acceleration. If any of the following events (each an “Event of Default”) shall occur:

(a) Debtor shall fail to pay any principal of interest on this Promissory Note or any other sum due under this Promissory Note, any Transaction Document, or any other note or other agreement between Debtor and RACC when the same becomes due and such failure shall continue for ten (10) days beyond the due date of such payment;

C-3

(b) Debtor shall fail to perform any term, covenant or agreement contained in any of the Transaction Documents and such failure shall continue for thirty (30) days after written notice;

(c) any representation or warranty of Debtor in any of the Transaction Documents or in any certificate or notice given in connection therewith shall have been false or misleading in any material respect at the time made or deemed to have been made;

(d) Debtor shall be in default under any agreement or agreements evidencing

(e) any other debt and similar monetary obligations (including, without limitation, capitalized leases, synthetic leases or securitization transactions) (collectively, “Indebtedness”) owing to RACC or any of its affiliates, or (ii) any other Indebtedness in excess of $100,000.00 in aggregate principal amount, or shall fail to pay any such Indebtedness when due or within any applicable period of grace;

(f) Debtor (i) shall make an assignment for the benefit of creditors; (ii) shall be adjudicated bankrupt or insolvent; (iii) shall seek the appointment of, or be the subject of an order appointing, a trustee, liquidator or receiver as to all or part of its assets, (iv) shall commence, approve or consent to, any case or proceeding under any bankruptcy, reorganization or similar law and, in the case of an involuntary case or proceeding, such case or proceeding is not dismissed within forty-five (45) days following the commencement thereof, or (v) shall be the subject of an order for relief in an involuntary case under federal bankruptcy law;

(g) Debtor shall be unable to pay its debts as they mature;

(h) there shall remain undischarged for more than thirty (30) days any final judgment or execution action against Debtor that, together with other outstanding claims and execution actions against Debtor, respectively, exceeds $100,000.00 in the aggregate;

(j) any of the Aircraft shall have been lost, stolen or confiscated or shall have incurred substantial damage or have been destroyed to such an extent that the repair thereof is impracticable (as determined solely by RACC);

(k) Debtor (i) sells, transfers or disposes of all or substantially all of its respective stock, assets or property, (ii) becomes the subject of, or engages in, a leveraged buy-out, or (iii) terminates its existence by merger, reorganization or consolidation; or if, for any reason, including, without limitation, as a result of a stock issuance or other capital event, there is a change in control of forty percent (40%) or more of Debtor’s voting capital stock issued and outstanding from time to time on a fully-diluted basis (and taking into account all voting capital stock than any persons have the right to acquire pursuant to any option or conversion rights); or

(l) an Event of Default as defined in the Restructuring Agreement shall occur;

(1) In the case of any Event of Default under clauses (f) or (g), the entire unpaid principal amount of this Promissory Note and all other amounts payable hereunder, shall automatically become forthwith due and payable, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived by Debtor; and

(2) In the case of any Event of Default other than under clauses (f) or (g), RACC may, by written notice to Debtor, declare the unpaid principal amount of this Promissory Note and all other amounts payable hereunder, to be forthwith due and payable, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by Debtor.

In addition to and without in any way limiting the foregoing, upon the occurrence of an Event of Default or at any time thereafter, RACC may employ all remedies allowed by law, including, without limitation, those available to a secured party under the Uniform Commercial Code. No remedy herein conferred upon RACC is intended to be exclusive of any other remedy and each and every remedy shall be cumulative and in addition to every other remedy hereunder, now or hereafter existing at law or in equity or otherwise.

13. Obligations Absolute. Debtor’s payment and performance obligations under this Promissory Note and the other Transaction Documents are absolute and unconditional. Any claim that Debtor may now or hereafter have against RACC or any affiliate thereof arising out of or in connection with the Aircraft, any of the other Collateral or any other matter shall not affect or excuse the unconditional obligation of Debtor to make any payment required to be made to RACC under the Transaction Documents, and shall not be used or asserted as a defense to payment of such obligation or as set-off, counterclaim or deduction against such payment. RACC shall have no obligation or responsibility with respect to any dispute that may arise between Debtor and any such foregoing person, and no such dispute shall prevent RACC from taking such action as it may deem appropriate in order to preserve, protect or enforce its rights hereunder.

14. Debtor’s Agreement to Pay Enforcement Costs, Etc. Debtor further agrees to pay to RACC, on demand, all costs and expenses (including court costs and legal expenses) incurred or expended by RACC in connection with the Obligations, this Promissory Note and the enforcement hereof, together with interest on amounts recoverable under this Section 14 from the time when such amounts become due until payment, whether before or after judgment, at the Default Interest Rate, provided that if such interest exceeds the maximum amount permitted to be paid under applicable law, then such interest shall be reduced to such maximum permitted amount.

15. Waiver of Default. No waiver by RACC of any default shall be effective unless in writing, nor operate as a waiver of any other default or of the same default in the future.

Any surplus proceeds are to be paid to Debtor.

6. Power of Attorney. Debtor hereby appoints RACC and its assigns or their designated agent as Debtor’s attorney-in-fact, irrevocably, with full power of substitution, to collect all payments with respect to the Collateral, to receive all moneys (including, but not limited to, refunds or proceeds of insurance) that may become due under any policy insuring the Collateral and all awards payable in connection with the condemnation, requisition or seizure of the Collateral, or any part thereof, to execute proofs of claim, to endorse drafts, checks and other instruments for the payment of money payable to Debtor in payment of such insurance moneys and to do all other acts, things, take any actions (including the filing of financing statements or other documents, including, without limitation, those documents referred to in Section 3 hereof) or institute any proceedings that RACC may deem to be necessary or appropriate at any time to protect and preserve the interest of RACC in the Collateral, or in this Security Agreement or the Restructuring Agreement.

7. Debtor’s Possession. Until default, Debtor may have possession of the Collateral and use it in any lawful manner not inconsistent with this Security Agreement.

At its option, but without assuming any obligation to do so, RACC may discharge taxes, liens or security interests, or other encumbrances levied or asserted against the Collateral, may place and pay for insurance thereon, may order and pay for the repair, maintenance and preservation thereof, and may pay any necessary filing or recording fees. Amounts paid by RACC under the preceding sentence shall constitute Obligations, shall be secured by the Collateral and shall be payable upon demand, together with interest at the Default Interest Rate as defined in the Restructuring Agreement until the Obligations are paid in full.

G-5

Aircraft or any part thereof, or in any way relating to or arising out of the manufacture, inspection, construction, purchase, pooling, interchange, acceptance, rejection, ownership, titling or re-titling, delivery, lease, sublease, possession, use, operation, maintenance, management, condition, registration or re-registration, sale, return, removal, repossession, storage or other disposition of the Aircraft or part thereof or any accident in connection therewith (including, without limitation, latent and other defects, whether or not discoverable, and any Claim for patent, trademark or copyright infringement).

Notwithstanding the foregoing, Debtor shall not be required to indemnify RACC for (a) any Claim caused solely and directly by the gross negligence or willful misconduct of the RACC or (b) any Claim in respect of the Aircraft arising from acts or events which occur after any and all other obligations of any kind whatsoever of Debtor hereunder and under the other Transaction Documents have been fully paid and/or performed, as the case may be, unless any such Claims were caused by Debtor (or any stockholder, director, officer, employee, successor, assignee, agent or servant of Debtor) or resulted or arose, directly or indirectly, from any acts, events or omissions of any kind whatsoever during the term hereof.

The liability of Debtor to make indemnification payments shall, notwithstanding any expiration or other termination (whether voluntary, as the result of an Event of Default, or otherwise) hereof or any of the other Transaction Documents, continue to exist until such indemnity payments are irrevocably made in full by Debtor and received by RACC. If any Claim is made against Debtor or RACC, the party receiving notice of such Claim shall promptly notify the other, but the failure of the party receiving notice to so notify the other shall not relieve Debtor of any obligation hereunder.

9. Event of Default. Upon the occurrence of an Event of Default, as defined in the Restructuring Agreement, (a) RACC shall have the right to exercise all remedies allowed by law, including, without limitation, those available to a secured party under the Uniform Commercial Code and (b) RACC may require Debtor to assemble the Collateral and make it available to RACC at a place to be designated by RACC which is reasonably convenient to both parties. The requirements of the Kansas Uniform Commercial Code and, if applicable, the Cape Town Treaty for reasonable notification to Debtor of the time and place of any proposed public sale of the Collateral or of the time after which any private sale or other intended disposition is to be made, shall be met if such notice is mailed, postage prepaid, to Debtor’s address, as shown herein, at least twenty (20) days before the time of the sale or disposition. After deduction of all reasonable expenses of retaking, holding, preparing for sale or lease, selling, leasing and the like, together with reasonable costs of collection, attorneys’ fees and legal expenses of RACC, the balance, if any, of the proceeds of the sale may be applied to the payment of any or all other Obligations, and to the satisfaction of indebtedness secured by any subordinate security interest in the Collateral of which RACC has received notice prior to distribution of the proceeds. Debtor shall be liable for any deficiency after application of such proceeds, to the extent permitted by law. After the occurrence of an Event of Default, Debtor agrees that RACC may fly or otherwise move the Aircraft for demonstration and other purposes reasonably related to a proposed public or private sale or other disposition of the Collateral. Notwithstanding the foregoing, RACC may at its option and in its sole discretion keep idle, lease, or use or operate the Aircraft without any liability whatsoever. To the extent permitted by applicable law, Debtor hereby waives any rights now or hereafter conferred by statute or otherwise which may require RACC to sell, lease or

G-6

otherwise use the Aircraft in mitigation of RACC’s damages as set forth in this Section or otherwise provided herein or which may otherwise limit or modify any of RACC’s rights or remedies under this Section or otherwise provided herein. Additionally, Debtor affirmatively agrees Secured Party has all the rights and remedies granted a creditor under the Cape Town Treaty, including but not limited to the following; (a) if Debtor is in possession, custody or control of the Collateral to enter Debtor’s or any other person’s premises and take possession of such Collateral; (b) to require Debtor to assemble and make available such Collateral at a location selected by Secured Party; (c) to sell, lease or otherwise dispose or cause the Debtor to sell, lease or otherwise dispose of the Collateral; (d) to collect or receive any income, rents or profits arising from the management or use of the Collateral; (e) to procure the deregistration of the Registration of the Aircraft and export of the Aircraft to a jurisdiction of Secured Party’s choice pursuant to the IDERA and as authorized by the Cape Town Treaty; and (f) to apply for a court order authorizing these remedies. At the option of Secured Party, upon default, it may also, pending final determination of its claim in any court proceeding, obtain speedy relief in the form of on order providing for (i) preservation of the object and its value; (ii) possession, control or custody of the object; (iii) immobilization of the object; (iv) lease or, except where covered by sub-paragraphs (i) to (iii), management of the object and the income therefrom; and (v) sale and application of proceeds therefrom (with all such remedies being governed by applicable law and the provisions herein).

10. Waiver of Default. No waiver by RACC of any default shall be effective unless in writing, nor operate as a waiver of any other default or of the same default in the future.

11. Restriction on Transfer or Liens. Debtor will not, without the prior written consent of RACC, sell or otherwise transfer or encumber the Collateral, or any interest therein, or offer to do so or permanently remove or attempt to permanently remove the Collateral from the United States. Debtor will keep the Collateral free from any adverse security interest, registration of any interest on the International Registry, lien or encumbrance and will not permit the Collateral to be attached or replevied. Debtor hereby consents to any and all assignments of this Security Agreement.

12. Taxes. Debtor will promptly pay, or cause to be paid, when due, all taxes and assessments upon the Collateral or upon its use or operation or upon this Security Agreement and the Obligations.

13. Change of Address. Debtor will notify RACC in writing of any change of address from that shown in this Security Agreement within ten (10) days of such change.

14. Certain Definitions. The terms “Administrator”, “Contract of Sale”, “international interest”, “Prospective Contract of Sale”, “Prospective International Interest, “Professional User”, and “searchable” shall have the meanings given them in the Cape Town Treaty.

15. GOVERNING LAW AND CHOICE OF FORUM. THIS SECURITY AGREEMENT WAS MADE AND ENTERED INTO IN THE STATE OF KANSAS AND THE LAW GOVERNING THIS TRANSACTION SHALL BE THAT OF THE STATE OF KANSAS AS IT MAY FROM TIME TO TIME EXIST. THE PARTIES AGREE THAT ANY LEGAL PROCEEDING BASED UPON THE PROVISIONS OF THIS

G-7

SECURITY AGREEMENT SHALL BE BROUGHT EXCLUSIVELY IN EITHER THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF KANSAS AT WICHITA, KANSAS, OR IN THE EIGHTEENTH JUDICIAL DISTRICT COURT OF SEDGWICK COUNTY, KANSAS, TO THE EXCLUSION OF ALL OTHER COURTS AND TRIBUNALS. NOTWITHSTANDING THE ABOVE, IN THE EVENT AN “EVENT OF DEFAULT” SHOULD OCCUR, RACC (AT ITS SOLE OPTION) MAY INSTITUTE A LEGAL PROCEEDING IN ANY JURISDICTION AS MAY BE APPROPRIATE IN ORDER FOR RACC TO OBTAIN POSSESSION OF THE COLLATERAL. THE PARTIES HEREBY CONSENT AND AGREE TO BE SUBJECT TO THE JURISDICTION OF THE AFORESAID COURTS IN SUCH PROCEEDINGS.

16. WAIVER OF RIGHT TO JURY TRIAL. ALL PARTIES TO THIS SECURITY AGREEMENT HEREBY VOLUNTARILY, KNOWINGLY AND IRREVOCABLY WAIVE ANY CONSTITUTIONAL OR OTHER RIGHT EACH MAY HAVE TO A TRIAL BY JURY IN THE EVENT OF LITIGATION CONCERNING THIS SECURITY AGREEMENT.

17. Damages. To the extent that any party hereto is subject to liability for any breach under this Security Agreement, the liability of such party shall be limited to the actual and direct monetary damages caused by such breach. In no event shall any party hereto be liable for indirect, special, consequential, multiple or punitive damages, or any damage deemed to be of an indirect or consequential nature arising out of or related to its performance hereunder, whether based upon breach of contract, warranty, negligence and whether grounded in tort, contract, civil law or other theories of liability, including strict liability. To the extent that this limitation of liability conflicts with any other provision(s) in this Security Agreement, said provision(s) shall be regarded as amended to whatever extent required to make such provision(s) consistent with this Section 17.

18. Enforceability. The unenforceability of any provision hereof shall not affect the validity of any other provision hereof.

19. Binding Agreement. All obligations of Debtor hereunder shall bind the heirs, agents and attorneys-in-fact, successors and assigns of Debtor. All rights of RACC hereunder shall inure to the benefit of its successors and assigns.

20. Assignment. RACC may transfer or assign all or any part of its interest in this Security Agreement without the consent of Debtor or any other party, and Debtor hereby consents to any future assignment by RACC hereunder. Debtor shall not sell, assign, transfer, encumber or convey any of its interests in the Collateral or in this Security Agreement without the prior written consent of RACC.

G-8

22. Miscellaneous. Time is of the essence hereof. RACC’s failure to insist on performance of any of the terms and conditions contained in this Security Agreement, the Restructuring Agreement or the other Transaction Documents or to exercise any right or benefit will not constitute a waiver unless the waiver is in writing, executed by an authorized representative of RACC. RACC’s waiver of any default hereunder or thereunder will not thereafter waive those terms, conditions, rights or privileges, whether of the same or a similar type.

The Anti-Dilution Shares, when issued, shall be duly authorized, fully paid and nonassessable shares of Common Stock. The certificates for the Anti-Dilution Shares shall be issued in the name of RACC (or RACC’s transferee or designee), and delivered to such person within three (3) business days after the Additional Issuance Date.

In the event of the issuance of any Anti-Dilution Shares, Great Lakes will promptly either (i) amend the Shelf Registration to include such Anti-Dilution Shares or (ii) or file an additional Shelf Registration with respect to such Anti-Dilution Shares. Great Lakes shall not allow the effectiveness of the Shelf Registration to lapse at any time after its initial effectiveness as a result of events within Great Lakes’ control. If, at any time after its initial effectiveness, the Shelf Registration shall cease to be effective as the result of events beyond Great Lakes’ control, Great Lakes shall at all times thereafter use its best efforts to reinstate the effectiveness of the Shelf Registration.
