3. Great Lakes agrees that at any time and from time to time upon the written request of the Lender, Great Lakes, at its sole cost and expense, will promptly and duly execute and deliver or cause to be duly executed and delivered any and all such further instruments and documents as the Lender may reasonably deem necessary or desirable, by reference to prudent industry practice, in obtaining the full benefits of the assignment hereunder and/or intended to be effected hereunder and of the rights and powers herein granted and/or intended to be granted hereunder including, without limitation, taking such steps as may be required to establish, maintain or enforce the Lien intended to be granted hereunder in full force and effect (whether under the UCC, Title 49, or the law of any other jurisdiction under which any Aircraft or other portion of the Collateral may be registered).

4. Great Lakes hereby warrants and represents that none of the Collateral is currently subject to any assignment, pledge or other Lien (other than Permitted Liens), and hereby covenants that Great Lakes will not otherwise assign or pledge, so long as the Lien of this Mortgage has not been discharged in accordance with the terms hereof, any of its rights, title or interests hereby assigned to any Person other than the Lender.

5. No other conveyance, assignment or act on the part of Great Lakes or the Lender shall be necessary for any part of the Collateral to become subject to the Lien of this Mortgage.

6. The Collateral shall be subject to release as and to the extent provided in Article 5 hereof.

7. Great Lakes agrees that it will timely and completely pay and perform all of its obligations under this Mortgage and the other Credit Documents.

ARTICLE 2

COVENANTS OF GREAT LAKES

Great Lakes represents, warrants and covenants, which representations, warranties and covenants shall survive execution and delivery of this Mortgage, as follows:

Section 2.01 Possession, Operation and Use, Maintenance and Registration.

(a) Possession. Without the prior written consent of the Lender, Great Lakes shall not lease or otherwise in any manner deliver, transfer or relinquish possession of any Airframe, any Engine or Spare Engine, or any Propeller or Spare Propeller or install any Engine, Spare Engine, Propeller, or Spare Propeller or permit any Engine, Spare Engine, Propeller or Spare Propeller to be installed, on any airframe other than an Airframe; provided that Great Lakes may without the prior written consent of the Lender:

(i) deliver possession of any Airframe or any Engine, Spare Engine, Propeller or Spare Propeller to any Person for testing, service, repair, restoration, storage, maintenance or other similar purposes or for alterations, modifications or additions to such Airframe or such Engine, Spare Engine, Propeller or Spare Propeller to the extent required or permitted by the terms hereof; and

(ii) install an Engine or Spare Engine or a Propeller or Spare Propeller on an airframe owned by Great Lakes free and clear of all Liens, except Permitted Liens;

provided that the rights of any Person who receives possession of any Airframe, any Engine, any Spare Engine, any Propeller or any Spare Propeller by reason of a transfer permitted by this Section 2.01(a) shall be subject and subordinate to all the terms of this Mortgage, including the Lender’s rights to repossess pursuant to Section 4.02, and Great Lakes shall remain primarily liable hereunder for the performance and observance of all of the terms and conditions of this Mortgage, to the same extent as if such transfer had not occurred, and no transfer of possession otherwise in compliance with this Section 2.01 shall (x) result in the maintenance, operation or use thereof that does not comply with Section 2.01(b) and (c), or (y) permit any action not permitted to be taken by Great Lakes with respect to any Aircraft hereunder.

(b) Operation and Use. Great Lakes agrees that no Aircraft, Airframe, Engine, Spare Engine, Propeller, or Spare Propeller will be maintained, used or operated in violation of any law, rule or regulation of any Governmental Authority having jurisdiction over such Aircraft, Airframe, Engine, Spare Engine, Propeller or Spare Propeller or in violation of any airworthiness certificate, license or registration relating to such Aircraft issued by any such Governmental Authority, except for unanticipated, minor or non-recurring violations, and except to the extent Great Lakes is contesting in good faith the validity or application of any such law, rule or regulation in any manner that does not involve any material risk of sale, forfeiture or loss of such Aircraft, Airframe, Engine, Spare Engine, Propeller or Spare Propeller or any material risk of subjecting the Lender to criminal liability or materially impair the Lien of this Mortgage; provided that Great Lakes shall only be entitled to contest mandatory grounding orders if it does not operate such Aircraft or Spare Engine during such contest. Great Lakes will not operate any Aircraft, Airframe, Engine, Spare Engine, Propeller or Spare Propeller or permit any Aircraft, Airframe, Engine, Spare Engine, Propeller or Spare Propeller to be operated or located, (i) in any area excluded from coverage by any insurance required by the terms of the Loan Agreement or (ii) in any war zone or other areas of hostilities.

(c) Maintenance. Great Lakes shall maintain, service, repair and overhaul each Aircraft, Airframe, Engine, Spare Engine, Propeller and Spare Propeller (or cause the same to be done) so as to keep each Aircraft, Airframe, Engine, Spare Engine, Propeller and Spare Propeller in good operating condition and in such condition as may be necessary to enable the airworthiness certification of each Aircraft to be maintained in good standing at all times (other than during temporary periods of storage, during maintenance, testing or modification permitted hereunder, or during periods of grounding by applicable Governmental Authorities, unless such grounding is due to the failure by Great Lakes to maintain such Aircraft in accordance with the terms hereof) under Title 49, during such periods in which such Aircraft is registered under the laws of the United States, using the same standards as Great Lakes uses with respect to similar aircraft operated by Great Lakes in similar circumstances. In any case, each Aircraft, Airframe, Engine, Spare Engine, Propeller and Spare Propeller and Spare Part will be maintained in accordance with the maintenance standards required by the FAA.

(d) Identification of the Lender’s Interest. (i) Great Lakes agrees to affix as promptly as practicable after the Closing Date and thereafter to maintain in the cockpit of each Aircraft, in a clearly visible location, and (if not prevented by applicable law or regulations) on each Engine and Spare Engine a nameplate bearing the inscription “MORTGAGED TO CALLIDUS CAPITAL CORPORATION” (such nameplate to be replaced, if necessary, with a nameplate reflecting the name of any successor Lender).

(ii) On or prior to the Closing Date and from time to time thereafter, Great Lakes shall install signs, in size and form reasonably satisfactory to the Lender, at each of the Designated Spare Parts Locations in which the Pledged Spare Parts are stored and otherwise as may be directed by the Lender within each Designated Spare Parts Location, bearing the inscription: “MORTGAGED TO CALLIDUS CAPITAL CORPORATION” (such sign to be replaced if there is a successor Lender).

(e) Registration. Great Lakes shall cause each Aircraft to remain duly registered, under the laws of the United States, in the name of Great Lakes and no Aircraft shall be registered under the laws of any other country.

Section 2.02 Replacement of Parts; Alterations, Modifications and Additions.

(a) Replacement of Parts. Great Lakes, at its own cost and expense, will promptly replace or cause to be replaced all Parts which may from time to time become worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use for any reason whatsoever. In addition, Great Lakes may remove in the ordinary course of maintenance, service, repair, overhaul or testing, any Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or rendered permanently unfit for use; provided that Great Lakes replaces such Parts as promptly as practicable. All replacement Parts shall be owned by Great Lakes free and clear of all Liens (except Permitted Liens and replacement parts temporarily installed on an emergency basis) and shall be in the condition and repair required by the terms hereof. All Parts at any time removed from any Airframe, Engine, Spare Engine, Propeller or Spare Propeller shall remain the property of Great Lakes and subject to the Lien of this Mortgage, no matter where located, until such time as such Parts shall be replaced by Parts which meet the requirements for replacement Parts specified herein. Immediately upon any replacement Part becoming incorporated or installed in or attached to the applicable Airframe, Engine, Spare Engine, Propeller, or Spare Propeller without further act (subject only to Permitted Liens and except replacement parts temporarily installed on an emergency basis), such replacement Part shall become the property of Great Lakes and subject to the Lien of this Mortgage and be deemed a Part for all purposes hereof to the same extent as the Parts originally incorporated or installed in or attached to such Airframe, Engine, Spare Engine, Propeller or Spare Propeller and the replaced Part shall be free and clear of all rights of the Lender hereunder and shall no longer be deemed a Part hereunder. Upon request of Great Lakes from time to time, the Lender shall, at the sole cost and expense of Great Lakes, execute and deliver to Great Lakes an appropriate instrument confirming the release of any such replaced Part from the Lien of this Mortgage.

(b) Reserved.

(c) Alterations, Modifications and Additions. Great Lakes, at its own expense, will make (or cause to be made) such alterations and modifications in and additions to each Airframe, Engine, Spare Engine, Propeller and Spare Propeller as may be required to be made from time to time so as to comply with any law, rule, regulation or order of any Governmental Authority; provided, however, that Great Lakes may, in good faith, and by appropriate proceedings contest the validity or application of any such law, rule, regulation or order in any reasonable manner, that does not subject Lender to any material risk of any civil or any criminal penalties, or involve any material risk of loss or forfeiture of title to any Airframe, Engine, Spare Engine, Propeller, or Spare Propeller. In addition, Great Lakes, at its own expense, may from time to time add further parts or accessories and make or cause to be made such alterations and modifications in and additions to any Airframe, Engine, Spare Engine, Propeller or Spare Propeller as Great

Lakes may deem desirable in the proper conduct of its business, including removal (without replacement) sale or disposal of Parts which Great Lakes deems to be obsolete or no longer suitable or appropriate for use on such Airframe, Engine, Spare Engine, Propeller or Spare Propeller (such parts, “Obsolete Parts”); provided that no such alteration, modification, removal, sale, disposal or addition materially diminishes the fair market value or utility of such Airframe, Engine, Spare Engine, Propeller, or Spare Propeller below the fair market value or utility thereof immediately prior to such alteration, modification, removal or addition assuming such Airframe, Engine, Spare Engine, Propeller or Spare Propeller was then in the condition required to be maintained by the terms of this Mortgage. In addition, the fair market value (but not the utility) of an Airframe, Engine, Spare Engine, Propeller or Spare Propeller may be reduced by the fair market value, if any, of Obsolete Parts which shall have been removed so long as the aggregate fair market value of all Obsolete Parts which shall have been removed and not replaced with respect to any Aircraft shall not exceed $100,000 in the aggregate. All Parts incorporated or installed in or attached or added to an Airframe, Engine, Spare Engine, Propeller, or Spare Propeller as the result of such alteration, modification or addition (except those parts which are excluded from the definition of Parts) shall, without further act, become subject to the Lien of this Mortgage.

REMEDIES

Section 4.01 Event of Default. It shall be an Event of Default hereunder and for all purposes of the Cape Town Convention, if under the Loan Agreement an “Event of Default” shall occur and be continuing thereunder.

Section 4.02 Remedies with Respect to Collateral.

(a) Remedies Available. Upon (i) the occurrence and continuance of any Event of Default, the Lender may do one or more of the following:

(i) cause Great Lakes, upon the written demand of the Lender, at Great Lakes’ expense, to deliver promptly, and Great Lakes shall deliver promptly, all or such part of the Airframes, the Engines, the Spare Engines, the Propellers, the Spare Propellers or other Collateral as the Lender may so demand to the Lender or its order, or the Lender, at its option, may access the Tracking System and enter upon the premises where all or any part of the Airframes, the Engines, the Spare Engines, the Propellers, the Spare Propellers or other Collateral are located and take immediate possession (to the exclusion of Great Lakes and all Persons claiming under or through Great Lakes) of and remove the same by summary proceedings or otherwise together with any engine which is not an Engine or Spare Engine and any propeller which is not a Propeller or Spare Propeller but which is installed on an Airframe, subject to all of the rights of the owner, lessor, or lien holder of or with respect to such engine or propeller;

(ii) sell all or any part of the Airframes, Engines, Spare Engines, Propellers, Spare Propellers or other Collateral at public or private sale, whether or not the Lender shall at the time have possession thereof, as the Lender may determine, or otherwise dispose of, hold, use, operate, lease to others or keep idle all or any part of the Airframes, the Engines, Spare Engines, Propellers, Spare Propellers or other Collateral as the Lender, in its sole discretion, may determine, all free and clear of any rights or claims of whatsoever kind of Great Lakes, any person claiming by, through or under Great Lakes and any person holding an interest subordinate to the interests of the Lender hereunder; provided, however, that Great Lakes shall not be entitled at any time prior to any such disposition to redeem the Collateral by paying in full all of the Obligations; or

(iii) exercise any or all of the rights and powers and pursue any and all remedies of a secured party under the UCC of the State of New York (whether or not in effect in the jurisdiction in which enforcement is sought) or by any other applicable law (including, without limitation, the Cape Town Convention) or proceed by appropriate court action to enforce the terms or to recover damages for the breach hereof.

Upon every taking of possession of Collateral under this Section 4.02, the Lender may, from time to time, at the expense of Great Lakes, make all such expenditures for maintenance, insurance, repairs, replacements, alterations, additions and improvements to and of the Collateral as it may deem proper. In each such case, the Lender shall have the right to maintain, use, insure, operate, store, lease, control or manage the Collateral and to carry on business and to exercise all rights and powers of Great Lakes relating to the Collateral in connection therewith, as the Lender shall deem appropriate, including the right to enter into any and all such agreements with respect to the maintenance, use, insurance, operation, storage, leasing, control, management or disposition of the Collateral or any part thereof as the Lender may determine; and the Lender shall be entitled to collect and receive directly all tolls, rents, revenues, issues, income, products, proceeds and profits of the Collateral and every part thereof, without prejudice, however, to the right of the Lender under any provision of this Mortgage to collect and receive all cash held by, or required to be deposited with, the Lender hereunder. Such tolls, rents, revenues, issues, income, products, proceeds and profits shall be applied to pay the expenses of using, operating,

storage, leasing, control, management or disposition of the Collateral, and of all maintenance, insurance, repairs, replacement, alterations, additions and improvements, and to make all payments which the Lender may be required or may elect to make, if any, for taxes, assessments, insurance or other proper charges upon the Collateral or any part thereof (including the employment of engineers and accountants to examine, inspect and make reports upon the properties and books and records of Great Lakes), and all other payments which the Lender may be required or authorized to make under any provision of this Mortgage, as well as just and reasonable compensation for the services of the Lender, and of all Persons engaged and employed by the Lender.

In addition, Great Lakes shall be liable for all legal fees and other costs and expenses incurred by reason of the occurrence of any Event of Default or the exercise of the Lender’s remedies with respect thereto, including all costs and expenses incurred in connection with the retaking, return or sale of any Airframe, Engines, Spare Engines, Propellers, Spare Propellers or other Collateral in accordance with the terms hereof under the UCC of the State of New York, which amounts shall, until paid, be secured by the Lien of this Mortgage.

If any Event of Default shall have occurred and be continuing, or the Loans shall have been declared forthwith due and payable pursuant to the Loan Agreement, the Lender may at any time thereafter while any Event of Default shall be continuing, without notice of any kind to Great Lakes to the extent permitted by law, carry out or enforce any one or more of the actions and remedies provided in this Article 4 or elsewhere in this Mortgage or otherwise available to a secured party under the UCC as in effect at the time in New York State, whether or not any or all of the Collateral is subject to the jurisdiction of such UCC and whether or not such remedies are referred to in this Article 4.

Nothing in the foregoing shall affect the right of the Lender to receive all payments of principal of, and interest on, the Obligations held by the Lender and all other amounts owing to the Lender as and when the same may be due.

(b) Notice of Sale. The Lender shall give Great Lakes at least ten (10) days’ prior written notice of the date fixed for any public sale of any of its Airframes, Engines, Spare Engines, Propellers, Spare Propellers, Spare Parts or other Collateral, or the date on or after which any private sale will be held, which notice Great Lakes hereby agrees is reasonable notice.

(c) Receiver. If any Event of Default shall occur and be continuing, to the extent permitted by law, the Lender shall be entitled, as a matter of right as against Great Lakes, without notice or demand and without regard to the adequacy of the security for the Obligations or the solvency of Great Lakes, upon the commencement of judicial proceedings by it to enforce any right under this Mortgage, to the appointment of a receiver of the Collateral or any part thereof and of the tolls, rents, revenues, issues, income, products and profits thereof for the recovery of judgment for the indebtedness secured by the Lien created under this Mortgage or for the enforcement of any other proper, legal or equitable remedy available under applicable law.

(d) Concerning Sales. At any sale under this Article, the Lender may bid for and purchase the property offered for sale, may make payment on account thereof as herein provided, free of any right of redemption, stay valuation or appraisal on the part of Great Lakes (all said rights being hereby waived and released to the fullest extent permitted by law) and, upon compliance with the terms of sale, may hold, retain and dispose of such property without further accountability therefor. Any purchaser shall be entitled, for the purpose of making payment for the property purchased, to deliver any of the Obligations in lieu of cash in the amount which shall be payable thereon as principal or interest. Said Obligations, in case the amount so payable to the holders thereof shall be less than the amounts due thereon, shall be returned to the holders thereof after being stamped or endorsed to show partial payment.

Section 4.03 Waiver of Appraisement, Etc. Great Lakes, for itself and all who may claim under it, waives, to the extent that it lawfully may, all right to have the property in the Collateral marshalled upon any foreclosure hereof, and agrees that any court having jurisdiction to foreclosure under this Mortgage may order the sale of the Collateral as an entirety.

Section 4.04 Reserved.

Section 4.05 Remedies Cumulative. Each and every right, power and remedy hereby specifically given to the Lender or otherwise in this Mortgage shall be cumulative and shall be in addition to every other right, power and remedy specifically given under this Mortgage or the other Credit Documents or now or hereafter existing at law, in equity or by statute or treaty (including, without limitation, the Cape Town Convention) and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time or simultaneously and as often and in such order as may be deemed expedient by the Lender. All such rights, powers and remedies shall be cumulative and the exercise or the beginning of the exercise of one shall not be deemed a waiver of the right to exercise any other or others. No delay or omission of the Lender in the exercise of any such right, power or remedy and no renewal or extension of any of the Obligations shall impair any such right, power or remedy or shall be construed to be a waiver of any Event of Default or an acquiescence therein. No notice to or demand on Great Lakes in any case shall entitle it to any other or further notice or demand in similar or other circumstances or constitute a waiver of any of the rights of the Lender to any other or further action in any circumstances. In the event that the Lender shall bring any suit to enforce any of its rights hereunder and shall be entitled to judgment, then in such suit the Lender may recover reasonable expenses, including attorneys’ fees, and the amounts thereof shall be included in such judgment.

Section 4.06 Discontinuance of Proceedings. In case the Lender shall have instituted any proceeding to enforce any right, power or remedy under this Mortgage by foreclosure, sale entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Lender, then and in every such case Great Lakes, the Lender and each holder of any of the Obligations shall be restored to their former positions and rights hereunder with respect to the Collateral subject to the security interest created under this Mortgage, and all rights, remedies and powers of the Lender shall continue as if no such proceeding had been instituted (but otherwise without prejudice).
