deliver or permit the delivery or possession of the Airframe or Engines to the manufacturer thereof for testing or for other similar purposes, or to any organization for service, repair, maintenance or overhaul work on the Airframe or Engines or for alterations in or modifications or additions to the Airframe or Engines to the extent required or permitted by the terms hereof and the other Loan Documents; or

(iii)

permit use by any Subsidiary through the use of an operating agreement, lease or otherwise.

None of the permitted relinquishments of possession set forth in Section 3.4(e)(i) through Section 3.4(e)(iii) above shall affect the registration of the Aircraft or in any way discharge or diminish any of the Grantor’s obligations to the Mortgagee hereunder or under any other Loan Document or constitute a waiver of the Mortgagee’s right to remedies hereunder or thereunder.

(f) Records and Reports. The Grantor shall maintain or cause to be maintained accurate and complete records, logs, manuals and all other materials required by the FAA or any Applicable Foreign Jurisdiction to be maintained in respect of the Aircraft and each Engine. The Grantor shall promptly furnish or cause to be furnished to the Mortgagee such information as may be required to enable the Mortgagee to file any reports required to be filed by the Mortgagee with the FAA or any Applicable Foreign Jurisdiction because of the Mortgagee’s interest in the Airframe or any Engine and upon the occurrence of an Event of Default (upon the Mortgagee’s request) shall deliver to the Mortgagee the originals of all such documents in possession of the Grantor and copies of all such documents relating to Aircraft and Engines leased or sold to third parties.

(g) Maintenance. On the date hereof, the Aircraft and each Engine is in good repair and condition, is airworthy in all respects, and has been maintained in accordance with the manufacturer’s maintenance program. None of the Aircraft nor any Engine has sustained an Event of Loss (as hereinafter defined) or material damage since the date on which such Aircraft and Engines were acquired by the Grantor. Grantor will keep or will cause to be kept the Aircraft and each Engine in good repair and condition and airworthy in all material respects, but in any event in at least as good a condition as they are on the date hereof, reasonable wear and tear excepted, and will perform all checks and overhauls required by the FAA, by any Applicable Foreign Aviation Law and by the applicable manufacturer’s maintenance program. Without limiting the generality of the foregoing, the Grantor agrees further that it shall or shall cause the Aircraft and each Engine:

(i)

subject to the right to contest set forth in Section 3.3(h) hereof, to be maintained, serviced, repaired, overhauled, altered, modified, added to and tested in accordance with the standard practices for similar equipment (including, without limitation, to the extent required by law, by the FAA, any Applicable Foreign Aviation Law or by the relevant insurance carriers), which practices shall at all times be at or above the standard of the industry for maintenance of similar equipment;

- 12 -

(ii)

subject to clause (vi) in the definition of Event of Loss, to be maintained, serviced, repaired, overhauled and tested, so as to keep the Aircraft and Engines in such condition as may be necessary to enable any airworthiness certification, license or registration of the Aircraft and Engines to be maintained in good standing at all times under the FAA Act or by any Applicable Foreign Aviation Law and any other requirement of law and as shall be required by any and all applicable airworthiness directives, operators letters, mandatory service bulletins and non-mandatory service bulletins which affect airworthiness; and

(iii)

to be maintained in compliance with all warranties and manufacturer’s mandatory requirements.

(h) Replacement of Parts. The Grantor shall 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, the Grantor may remove or may cause to be removed in the ordinary course of maintenance, service, repair, overhaul or testing of any Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use; provided, however, that the Grantor will replace or will cause to be replaced such Parts as promptly as reasonably possible. All replacement Parts shall be free and clear of all Liens (other than Permitted Liens) and shall be in as good operating condition as, and shall be of a quality and utility at least equal to, the Parts replaced, assuming such replaced Parts were in the condition and repair required to be maintained by the terms hereof; provided, however, that the Grantor shall have the right to install or to cause to be installed temporary replacement Parts pending the completion of permanent repairs or installation of permanent replacement Parts, in which event the Grantor shall install or shall cause to be installed permanent replacement Parts to meet such requirements as soon as reasonably possible and in any event within ninety (90) days from the date of installation of such temporary replacement Parts. All Parts at any time removed from the Airframe or any Engine shall remain subject to the Lien created under this Mortgage no matter where located, until such time as such Parts shall be replaced by Parts which have been incorporated in the Aircraft or such Engine and which meet the requirements of subsections (i) and (ii) below. Immediately upon any replacement Part becoming incorporated or installed in or attached to the Airframe or any Engine as provided above, without further act, (i) such replacement Part shall become subject to the Lien created under this Mortgage and be deemed part of the Aircraft or such Engine for all purposes hereof to the same extent as the Parts originally incorporated in the Aircraft or such Engine (and the Grantor shall make, or cause to be made, all filings or registrations necessary to perfect the Mortgagee’s Lien in such Part), and (ii) the replaced Part shall be released from the Lien of this Mortgage and the replaced Part shall no longer be deemed a Part hereunder;

- 13 -

(i) Pooling of Parts. Any Part removed from the Aircraft or any Engine as provided in Section 3.4(h) may be subjected to a normal pooling arrangement customarily entered into by the Grantor and entered into in the ordinary course of business of the Grantor,, so long as a part replacing such removed Part shall be incorporated in such item as promptly as possible after the removal of such removed Part, provided that no such arrangement or permit requires or results in any change in registration of or transfer of title to the Airframe or any Engine. In addition, any replacement Part incorporated in the Aircraft or any Engine in accordance with Section 3.4(h) may be owned by another Person subject to such a normal pooling arrangement, so long as the Grantor promptly, either (i) causes title to or a first priority Lien in such replacement Part to vest in Grantor free and clear of all Liens except Permitted Liens, which replacement Part shall then be subject to the Lien created by this Mortgage, or (ii) replaces such replacement Part by incorporating or installing in or attaching to the Aircraft or any Engine from which it was removed a further replacement Part meeting the requirements of this Mortgage and owned by the Grantor or in which the Grantor has first priority Lien free and clear of all Liens (other than Permitted Liens) and by causing such replacement Part to be subject to the Lien created by this Mortgage as set forth in Section 3.4(h);

(j) Alterations, Modifications and Additions. Grantor shall make or shall cause to be made such alterations and modifications in and additions to the Aircraft and Engines as may be required from time to time to meet the requirements of the FAA or the Applicable Foreign Jurisdiction and to maintain the certificate of airworthiness therefor. In addition, the Grantor may make or may cause to be made from time to time such alterations and modifications in and additions to the Airframe or any Engine as the Grantor may deem desirable; provided that each such alteration, modification and addition is readily removable from the Aircraft or such Engine or that such alteration, modification or addition shall not diminish the value, utility or condition of the Aircraft or any Engine below the value, utility or condition thereof immediately prior to such alteration, modification or addition, assuming the Aircraft or such Engine was then of the value or utility and in the condition required to be maintained by the terms of this Mortgage; and provided, further, that no such, alteration, modification or addition shall cause the airworthiness certification or other license, registration or authorization of the Aircraft or any Engine to cease to be in good standing under the FAA Act or the Applicable Foreign Aviation Law. All Parts added to the Airframe or any Engine as the result of such alteration, modification or addition shall, without further act, be subject to the Lien created under this Mortgage. Notwithstanding the foregoing sentence of this Section 3.4(j), so long as no Event of Default shall have occurred and be continuing, the Grantor may remove or may cause to be removed any Part if (A) such Part is in addition to, and not in replacement of or substitution for, any Part originally incorporated in the Aircraft or any Engine at the time of delivery thereof or any Part in replacement of or substitution for any such Part or such Part is obsolete or no longer useful in the operation of the Aircraft or any Engine, (B) such Part is not required to be incorporated or installed in or attached or added to the Aircraft or any Engine pursuant to the terms of this Section 3.4, and (C) such Part can be removed from the Aircraft or such Engine without causing any material damage thereto. Upon the removal of any Part as provided above, such Part shall be released from the Lien created under this Mortgage.

- 14 -

(k) Nameplate. Grantor shall place and maintain, or shall cause to be placed and maintained, a fireproof plate to be provided by Mortgagee at Grantor’s reasonable sole cost and expense, in a reasonably prominent position on the flight deck or cockpit of each Airframe and on each Engine stating:

THIS GULFSTREAM AEROSPACE MODEL G-IV-SP AIRCRAFT IS OWNED BY 57 AVIATION SERVICES, LLC, AND IS SUBJECT TO A FIRST PRIORITY SECURITY INTEREST IN FAVOR OF CITICORP USA, INC.

(l) Pooling of Engines. Any Engine may be subjected to normal pooling arrangements customarily entered into by the Grantor and entered into in the ordinary course of business of the Grantor, so long as (i) no transfer of the registration of the Engine shall be effected in connection therewith and (ii) no such agreement or arrangement shall result in the transfer of title to the Engine, it being understood that a loss of title pursuant to such an arrangement shall be deemed to be an Event of Loss.

(m) Description of Airframe and the Engine. The description of the Airframe and the Engines set forth in Schedule III are accurate and complete descriptions and have been registered as such on the IR.

SECTION 3.5 Insurance Required.

Insurance. The Grantor shall at all times, at its own cost and expense, maintain, or cause to be maintained, a policy of insurance with respect to the Collateral, in accordance with the following provisions:

(a) The Grantor shall maintain in effect comprehensive third party aircraft liability insurance against bodily injury and property damage losses arising from ground, flight and taxiing exposures, including, but not limited to, passenger legal liability, cargo liability, contractual liability and products liability insurance, in an amount not less than $200,000,000 (or, if the Aircraft is operating within, into, out of, or over the territory of a member state of the European Union, such higher amount as may be required pursuant to Regulation 785/2004 of the European Parliament) for any one accident, or series of accidents arising out of any one event, with respect to the Aircraft. Such policy shall include war and allied risks in accordance with standard market practice (currently “The Extended Coverage Endorsement-AVN 52A”). Any such liability insurance policy may be subject to a deductible in an amount not to exceed $100,000 per occurrence. All such policies shall be maintained in effect with insurers and/or reinsurers of recognized standing in the international aviation industry and reasonably satisfactory to the Mortgagee.

(b) The Grantor shall maintain in effect with insurers and/or reinsurers of recognized standing in the international aviation industry and reasonably satisfactory to the Mortgagee: (A) all-risk ground and flight aircraft hull insurance covering the Aircraft (including taxiing exposures) with an agreed value loss valuation clause; (B) all-risk coverage with respect to any Engines, Parts or landing gear while removed from the Aircraft insured on a replacement cost basis; and (C) war risk and hijacking (including political/non-political hijacking and acts of terrorism) coverages, including, but not limited to, coverage against confiscation, expropriations,

- 15 -

nationalization or seizure, including the country of registry. All such insurance shall be in full force and effect throughout any geographical areas at any time traversed by the Aircraft, shall be payable in Dollars in the United States and shall be in the amount of not less than an “agreed upon value” of not less than one hundred five percent (105%) of the outstanding principal amount of the Loan. Any hull insurance carried in accordance with this Section 3.5 shall not contain any provision for self-insured amounts or a deductible, provided that such insurance may be subject to a deductible which does not exceed $100,000 per occurrence. Each Engine, after removal, shall be insured for not less than $2,500,000 under a ground risks policy reasonably acceptable to the Mortgagee.

(c) The Grantor will name or cause to be named Mortgagee as an additional insured on all policies of insurance and Mortgagee as sole loss payee to the Aircraft with respect to the aircraft hull insurance coverage. The Grantor shall cause all parties who may have an interest in the proceeds of such policies to acknowledge, in writing, that the Mortgagee has a prior interest in such proceeds. Each and every such policy under this Section 3.5 shall (i) provide that in respect of the interests of the Mortgagee in such policies, such insurance shall not be invalidated by any action or inaction of the Grantor, the Mortgagee or any other Person and shall insure the Mortgagee regardless of any breach or violation of any warranty, declaration or condition contained in such policies by the Grantor or any other Person; (ii) provide that, if such insurance is canceled for any reason whatever, or any material change is made in policy terms or conditions, or if such insurance is allowed to lapse for nonpayment of premium, such cancellation, change or lapse shall or not be effective as to Mortgagee for thirty (30) days, and in the case of any war risk or allied perils coverage, seven (7) days after receipt by them of written notice from such insurers or their authorized representatives of such cancellation, change or lapse; (iii) provide that such insurers shall hold harmless and waive any rights of subrogation against Mortgagee; (iv) be primary without right of contribution from any other insurance that with is carried by Mortgagee; (v) waive any rights of set-off, counterclaim or other deduction against Mortgagee; (vi) provide that Mortgagee shall have no obligation or liability for premiums, commissions, assessments, representations or warranties or calls in connection with such insurance; (vii) provide that all the provisions thereof, except the limits of liability, shall operate in the same manner as if there were a separate policy covering Mortgagee; and (viii) in respect to casualty insurance shall provide that proceeds shall be paid to Mortgagee so long as the Loan is outstanding.

(d) On or before the date of any advance of proceeds pursuant to the Loan and prior to the renewal or replacement date of any insurance policy required hereunder, the Grantor shall provide the Mortgagee with written certifications by a firm of independent insurance brokers reasonably acceptable to the Mortgagee with respect to the types, amounts and policy numbers of insurance in effect as of the date of execution and delivery of this Mortgage and certifying that in the opinion of such firm the insurance then carried and maintained complies with the terms of this Section 3.5. The original certificate of insurance shall be in a form acceptable to the Mortgagee.

(e) The Grantor shall not use or permit the Collateral to be used in any manner or for any purpose excepted from or contrary to the requirements of any insurance policy or policies required to be carried and maintained hereunder and shall not do any other act or permit anything to be done which could reasonably be expected to invalidate or limit any such insurance policy or policies.

- 16 -

(f) Power of Attorney. The Grantor hereby irrevocably makes, constitutes and appoints the Mortgagee (and all officers, employees or agents designated by the Mortgagee), for the benefit of the Mortgagee, effective upon the occurrence and during the continuance of an Event of Default, as the Grantor’s true and lawful attorney (and agent- in-fact) for the purpose of making, settling and adjusting claims under such policies of insurance, endorsing the name of the Grantor on any check, draft, instrument or other item or payment for the proceeds of such policies of insurance and for making all determinations and decisions with respect to such policies of insurance.

(g) Mortgagee May Act. In the event the Grantor (i) shall fail to maintain, or fail to cause to be maintained, the full insurance coverage required hereunder or (ii) shall fail to keep any of its Collateral in good repair and good operating condition subject to ordinary wear and tear, then the Mortgagee may (but shall be under no obligation to), without waiving or releasing any Obligation or Event of Default by the Grantor hereunder, contract for the required policies of insurance and pay the premiums on the same or make any required repairs, renewals and replacements; and all sums so disbursed by Mortgagee, including reasonable attorneys’ fees, court costs, expenses and other charges related thereto, shall be payable on demand by the Grantor to the Mortgagee and shall be additional Obligations secured by the Collateral.

(h) Payment for Uninsured Loss. The Grantor agrees that to the extent that it shall not carry insurance required by Section 3.5 hereof, it shall in the event of any loss or casualty pay promptly to the Mortgagee, for application in accordance with the provisions of Section 3.5(i) hereof, such amount as would have been received as Net Proceeds (as hereinafter defined) by the Mortgagee, had such insurance been carried to the extent required.

(i) Application of Insurance Proceeds. The Net Proceeds of the insurance carried pursuant to the provisions of Sections 3.5(a) and 3.5(b) hereof shall be applied by the Grantor toward extinguishment of the defect or claim or satisfaction of the liability with respect to which such insurance proceeds may be paid.

(j) Net Proceeds. “Net Proceeds” when used with respect to any insurance proceeds shall mean the gross proceeds from such proceeds, award or other amount, less all taxes, fees and expenses (including attorneys’ fees) incurred in the realization thereof.

(k) Notice of Loss. In case of any material damage to or destruction of all or any part of the Collateral pledged hereunder by the Grantor, the Grantor shall give prompt notice thereof to the Mortgagee. Each such notice shall describe generally the nature and extent of such damage, destruction, taking, loss, proceeding or negotiations. The Grantor is hereby authorized and empowered to adjust or compromise any loss under any such insurance.

- 17 -

(l) Mortgagee Insurance. Nothing herein shall prevent the Mortgagee from maintaining additional insurance at its own expense; provided that the maintenance of such insurance shall not prejudice the Grantor’s ability to obtain, or recover under, the insurance required under this Section 3.5 or materially increase the costs thereof.

(m) Insurance Coverage. On the date hereof, the Grantor shall deliver to the Mortgagee certificates of insurance evidencing the insurance coverage maintained in effect on the date hereof.

SECTION 3.6 Events of Loss; Governmental Authorities. As used herein, “Event of Loss” means, with respect to the Airframe or an Engine, any of the following events: (i) loss of such Airframe or Engine or of the use thereof due to the destruction of or damage to such Airframe or Engine to such extent as shall render repair thereof uneconomical, provided that such repair shall not be deemed uneconomical if the proceeds of insurance with respect to such damage or destruction (plus any applicable amounts of deductibles) shall be in an amount at least equal to the cost of such repair; (ii) any damage to such Airframe or Engine which results in an insurance settlement with respect to such Airframe or Engine on the basis of a total loss or a constructive or compromised total loss; (iii) the disappearance of such Airframe or Engine which shall have resulted in the loss of possession of such Airframe or Engine by the Grantor for a period of five (5) consecutive days; (iv) the theft of such Airframe or Engine which shall have resulted in the loss of Airframe or Engine by the Grantor for five (5) consecutive days; (v) the requisition of title, confiscation or seizure of such Airframe or Engine by any Governmental Authority for a period of thirty (30) consecutive days; (vi) as a result of any requirement by the FAA or other Governmental Authority, the use of such Airframe or Engine in the normal course of interstate air transportation shall be prohibited unless, prior to the expiration of such period, the Grantor shall have undertaken and shall be diligently carrying forward all steps which are necessary or desirable to permit the normal use of such Airframe or Engine, or, in any event, if such use shall have been prohibited for a period of 360 days; (vii) the operation or location of such Airframe or Engine in any area excluded from coverage by the insurance policies in effect with respect thereto required by the terms of Section 3.5; or (viii) any other event resulting in such Airframe or Engine being rendered unfit for normal use for any reason whatsoever for more than sixty (60) consecutive days. An Event of Loss with respect to an Aircraft shall be deemed to have occurred if an Event of Loss occurs with respect to the Airframe which constitutes a part of such Aircraft. Upon the occurrence of an Event of Loss, the provisions of this Section 3.6 shall apply, govern and control.

(a) Event of Loss with Respect to an Engine. Upon the occurrence of an Event of Loss with respect to one or more Engines (but not the Aircraft), the Grantor shall within three (3) Business Days of the Grantor’s actual knowledge of such occurrence give the Mortgagee written notice of such Event of Loss and shall comply with the terms of Section 3.6(a)(i).

(i)

Replacement of Engines. As promptly as practicable, and in any event on or before the Business Day next preceding the 90th day following the date of occurrence of such Event of Loss, the Grantor shall subject or cause to be subjected to this Mortgage in replacement thereof, a replacement Engine of the same model and

- 18 -

having not less than the same value as the Engine being replaced and which shall be free and clear of all Liens (other than Permitted Liens) and which shall be of like kind and not less than the same value as, and which shall be in as good operating condition as, the Engine so replaced (for such purpose, it shall be assumed that such Engine was in the condition and repair required by the terms hereof) and, following such replacement, the replaced Engine shall be released from the Lien created by this Mortgage. If the Grantor shall not perform its obligation to effect such replacement hereunder during the period of time provided herein, such failure shall be an Event of Default.

(ii)

Payment of Principal and Interest After Event of Loss. No Event of Loss shall limit the obligation of the Grantor to pay and perform the Obligations in accordance with the terms hereof.

(iii)

Conditions to Replacement of an Engine. In addition to the requirements contained in Section 3.6(a)(i), the Grantor’s obligation to replace an Engine as set forth in Section 3.6(a)(i) shall include the obligation of the Grantor to promptly, (all writings referred to below to be reasonably satisfactory in form and substance to the Mortgagee):

(A) furnish the Mortgagee with such evidence of title as the Mortgagee may reasonably request (including, without limitation, appropriate bills of sale);

(B) subject to the provisions of the Granting Clause and the proviso to Section 3.1 (a), cause a supplement to this Mortgage subjecting the replacement Engine to this Mortgage to be duly executed by a duly authorized officer, and, upon such execution, to be filed for recordation with the FAA pursuant to the FAA Act, the IR pursuant to the CTC or, if applicable, with the applicable Foreign Jurisdiction under the Applicable Foreign Aviation Law;

(C) furnish the Mortgagee with such evidence of compliance with the insurance provisions of Section 3.5 with respect to the replacement Engine, as may be reasonably requested, including, without limitation, insurance certificates confirming such compliance;

- 19 -

(E) furnish the Mortgagee with an opinion of counsel reasonably satisfactory to the Mortgagee, to the effect that the replacement Engine is free and clear of liens and encumbrances, other than Permitted Liens, and with respect to the effectiveness and priority of the interests which this Mortgage purports to create and to such further effect as the Mortgagee may reasonably request;

(F) furnish the Mortgagee with in the case of an Engine which is part of the Aircraft, a certificate from a qualified aircraft engineer certifying that the replacement Engine is of like kind and not less than the same value of the Engine so replaced (assuming the Engine was in the condition and repair required by the terms hereof immediately prior to the occurrence of such Event of Loss);

(G) furnish the Mortgagee with an affidavit from the Grantor stating (I) the model numbers of the replacement Engine, and the name of the manufacturer thereof, (II) that the replacement Engine is in good operating condition and repair, is of a type substantially similar to the Engine subject to such Event of Loss (which engine shall in any event be compatible with the other Engines or engines installed on the airframe) and meets the requirements of this Section 3.6(a)(iii), (III) that all conditions precedent provided for in Section 3.6(a)(i) and this Section 3.6(a)(iii) relating to such substitution have been complied with, (IV) that immediately prior to the subjection of such replacement Engine to the Lien created by this Mortgage it was free and clear of all Liens other than Permitted Liens and that the Lien created by this Mortgage thereon will constitute a valid and perfected first priority Lien, free and clear of all other Liens, other than Permitted Liens and (V) that all necessary approvals, authorizations, consents, licenses, certificates and orders of the United States or any agency or instrumentality thereof or any other Governmental Authority or instrumentality having jurisdiction have been duly obtained, and such approvals, authorizations, consents, licenses, certificates or orders are in full force and effect and constitute sufficient authorization therefor; and

(H) furnish such other certificates or documents related to Engines as Mortgagee may reasonably require.

(b) Event of Loss with Respect to the Aircraft. Upon the occurrence of an Event of Loss with respect to the Aircraft, the Grantor shall give the Mortgagee prompt written notice (and in any event within three (3) Business Days of the Grantor’s actual knowledge of such occurrence) thereof and Grantor shall, on or before the Business Day which is the earliest of (i) the sixtieth (60th) day following the date of the occurrence of such Event of Loss, or (ii) the second Business Day following the receipt of insurance proceeds with respect to such occurrence, prepay in full the Loan attributable to such Aircraft. In the event of payment in full by the Grantor of all amounts then due and payable hereunder in respect of the Aircraft having suffered the Event of Loss, all the Collateral shall be released from the Lien of this Mortgage and the Mortgage shall execute and deliver such instruments as may be reasonably required to evidence such release.

- 20 -

(c) Replacement of Engines. If insurance proceeds are received with respect to the Engine that has been or is being replaced (and which by the terms of this Section 3.6 may be replaced) by the Grantor pursuant to Section 3.6(a), such insurance proceeds shall be paid over to, or retained by, the Mortgagee, and at the time of such replacement in accordance with Section 3.6(a) so much of such insurance proceeds remaining after reimbursement of the Mortgagee for costs and expenses (and the Mortgagee is hereby authorized to so apply such insurance proceeds to such reimbursement) shall be paid over to the Grantor and as provided for in Section 3.5.

(d) Use of Aircraft Not Constituting an Event of Loss. If payments are received with respect to a requisition for use by any Governmental Authority which does not constitute an Event of Loss under the definition thereof, such payments may be retained by the Grantor.

(e) Default. Notwithstanding the foregoing provisions of this Section 3.6, any payments received at any time by the Mortgagee from any Governmental Authority or other Person, whether or not with respect to an Event of Loss, which are payable to the Grantor shall not be paid to the Grantor if at the time of such payment an Event of Default shall have occurred and be continuing, in which event all such amounts shall be paid to and held by the Mortgagee as security for the Obligations of the Grantor hereunder and under the other Loan Documents and applied by the Mortgagee toward the payment of such Obligations.

(f) Management of Aircraft. The Mortgagee acknowledges and agrees that during the term of the Loan, the Aircraft will be managed by Jet Aviation Business Jets, Inc. (or an affiliate thereof) or any other manager (the “Aircraft Manager”) acceptable to the Grantor. To the extent that any of the obligations set forth herein or in any other Loan Document has been performed by the Aircraft Manager, such performance shall be satisfactory for purposes of this Mortgage and such Loan Documents and shall constitute full performance hereunder and thereunder, as the case may be. Grantor agrees that any such management agreement may permit the Aircraft Manager to charter (but not lease or sublease) the Aircraft to third Persons other than the Grantor, the Guarantors or any Subsidiary.

ARTICLE IV

EVENTS OF DEFAULT AND REMEDIES

SECTION 4.1 Events of Default. Upon the occurrence of any of the following events for any reason whatsoever (and whether such occurrence shall be voluntary or involuntary or come about or be affected by operation of law or pursuant to or in compliance with any judgment, decree or order of any court or any order, rule or regulation of any Governmental Authority) (herein called “Events of Default”):

(a) An Event of Default under the Note.

- 21 -

SECTION 4.2 Remedies. If an Event of Default shall occur and be continuing, the Mortgagee may, without notice of any kind to the Grantor, carry out or enforce the actions or remedies provided in this Article IV or elsewhere in this Mortgage or in the Loan Documents or otherwise available to a secured party under the Uniform Commercial Code or other applicable law as in effect at the time in any applicable jurisdiction, including, without limitation, all remedies available to a chargee pursuant to Articles 8, 9, 12 and 13 of the CTC, and Articles IX and XIII of the Protocol and, further, may exercise any rights under the IDERA, including de-registering the Aircraft and Grantor acknowledges and agrees that, notwithstanding such de-registration and any subsequent de-registration, Grantor shall continue to be liable for the Obligations secured hereby. In furtherance of the foregoing, the Grantor hereby agrees that the Mortgagee may exercise all forms of interim relief available in accordance with Article 13 of the CTC and Article 9 of the Protocol.

SECTION 4.3 Possession of Aircraft. If an Event of Default shall have occurred and be continuing, the Mortgagee may, without notice, take possession of all or any part of the Aircraft and may exclude the Grantor and all persons claiming under the Grantor wholly or partly therefrom. If an Event of Default shall have occurred and be continuing, at the request of the Mortgagee, the Grantor shall promptly deliver or cause to be delivered to the Mortgagee or to whomsoever the Mortgagee shall designate, at such time or times and place or places as the Mortgagee may specify, and fly or cause to be flown to such airport or airports in the continental United States as the Mortgagee may specify, without risk or expense to the Mortgagee, all or any part of the Aircraft specified by the Mortgagee.

The Grantor agrees to pay to the Mortgagee, all expenses incurred in taking any such action; and all such expenses shall, until paid, be secured by the lien and security interest of this Mortgage. Upon every such taking of possession, the Mortgagee may, from time to time, make all such reasonable expenditures for maintenance, insurance, repairs, replacements, alterations and additions to and of the Aircraft as it may deem proper and such expenditures shall constitute obligations secured hereby.

SECTION 4.4 Receiver. If an Event of Default shall have occurred and be continuing, the Mortgagee shall be entitled, as a matter of right as against the Grantor without notice or demand and without regard to the adequacy of the security for the Obligations by virtue of this Mortgage or any other collateral or to the solvency of the Grantor upon the commencement of judicial proceedings by it to enforce any right under this Mortgage, to the appointment of a receiver of all or any part of the Collateral.

SECTION 4.5 Sale and Suits for Enforcement. If an Event of Default shall have occurred and be continuing, the Mortgagee, with or without taking possession of the Aircraft, may

- 22 -

(a) to the extent and in the manner permitted by law, sell at one or more sales, as an entirety or in separate lots or parcels, all or any part of the Aircraft, as the Mortgagee may decide, at public or private sale, at such place or places and at such time or times and upon such terms, including terms of credit (which may include the retention of title by the Mortgagee to the property so sold), as the Mortgagee may determine, whether or not the Aircraft shall be at the place of sale; and

(b) proceed to protect and enforce its rights under this Mortgage by suit, whether for specific performance of any covenant herein contained or in aid of the exercise of any power herein granted or for the foreclosure of this Mortgage and the sale of the Collateral under the judgment or decree of a court of competent jurisdiction or for the enforcement of any other right.

(i)

At any sale of an Aircraft or any part thereof by the Mortgagee pursuant to paragraph (a) above, the Mortgagee may consider and accept bids requiring the extension of credit to the bidder and may determine the highest bidder at such sale, whether or not the bid of such bidder shall be solely for cash or shall require the extension of credit. The Mortgagee shall be entitled to bid in unpaid Obligations in the same manner as cash in any sale of the Collateral, public or private, at foreclosure or otherwise.

(ii)

The Mortgagee, to the extent permitted by law, may from time to time adjourn any sale under paragraph (a) above by announcement at the time and place appointed for such sale or for any adjournment thereof; and without further notice or publication, except as may be required by applicable law, such sale be made at the time and place to which the same shall have been so adjourned.

(iii)

Upon the completion of any sale under paragraph (a) above, full title and right of possession to the Aircraft so sold shall (subject to any retention of title by the Mortgagee as part of the terms of such sale) pass to the accepted purchaser forthwith upon the completion of such sale, and the Grantor shall deliver, in accordance with the instructions of the Mortgagee (including flying the Aircraft or causing the same to be flown to such airports in the continental United States as the Mortgagee may specify), such Aircraft so sold. If the Grantor shall for any reason fail to deliver such Aircraft, the Mortgagee shall have all of the rights granted by Section 4.3 hereof. The Mortgagee is hereby irrevocably appointed the true and lawful attorney of the Grantor in its name and stead, to make all necessary conveyances of the Aircraft so sold. Nevertheless, if so requested by the Mortgagee or by any purchaser, the Grantor shall confirm any such sale or conveyance by executing and delivering all proper instruments of conveyance or releases as may be designated in any such request.

- 23 -

SECTION 4.6 Waiver of Appraisement, etc. The Grantor agrees, to the fullest extent that it lawfully may, that it will not (and hereby irrevocably waive its right to) at any time plead, or claim the benefit or advantage of, any appraisement, valuation, stay, extension, moratorium or redemption law now or hereafter in force, in order to prevent or hinder the enforcement of this Mortgage or the absolute sale of the Collateral.

SECTION 4.7 Remedies Cumulative. No remedy herein conferred upon the Mortgagee is intended to be exclusive of any other remedy, but every such remedy shall be cumulative, but shall not be duplicative, and shall be in addition to every other remedy herein conferred or now or hereafter existing in law.

SECTION 4.8 Application of Proceeds. If an Event of Default shall have occurred and be continuing, the proceeds of any sale, lease or other disposition of all or any part of the Collateral pursuant to this Mortgage and all other sums realized or held by the Mortgagee under this Mortgage or any proceedings hereunder shall be applied in the following order of priority (unless otherwise directed by the Mortgagee):

First: To the payment of the expenses of any such sale, lease, disposition or other realization (and of the retaking, holding and preparing for sale or lease), including reasonable compensation to the Mortgagee’s agents and counsel involved therewith, and all expenses, liabilities and advances made or incurred by the Mortgagee in connection therewith, including, without limitation, taxes upon or with respect to such sale, lease, disposition or realization and the payment of taxes and Liens, if any, prior to the Lien of this Mortgage;

Second: To the payment of the Obligations in whole or in part in accordance with the Note; and

Third: To the Grantor or as any court of competent jurisdiction may otherwise direct.

SECTION 4.9 Delay or Omission; Possession of Note.

(a) Delay or Omission. No delay or omission of the Mortgagee to exercise any right or remedy arising upon the happening of any Default or Event of Default shall impair any right or remedy or shall be construed to be a waiver of any such Default or Event of Default or an acquiescence therein; and every right and remedy given to the Mortgagee by this Article IV or by applicable law may be exercised from time to time and as often as may be deemed expedient by the Mortgagee.

(b) Possession of Note. All rights of action under this Mortgage may be enforced by the Mortgagee without the possession of the Note or any other instrument or document evidencing any Obligation or the production thereof in any proceeding.

ARTICLE V

MISCELLANEOUS PROVISIONS

SECTION 5.1 Amendments, etc. No amendment or waiver of any provision of this Mortgage nor consent to any departure by the Grantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Mortgagee and the Grantor and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

SECTION 5.2 Notices. All notices, requests and demands to or upon the respective parties hereto to be effective shall be given in accordance with the Note to the address of each party as set forth above.

SECTION 5.3 Continuing Lien and Security Interest; Transfer. This Mortgage shall create a continuing lien and security interest in the Collateral and shall (i) remain in full force and effect until payment and performance in full of all of the Obligations, (ii) be binding upon the Grantor, its respective successors and assigns, and (iii) inure, together with the rights and remedies of the Mortgagee hereunder, to the benefit of the Mortgagee, and its successors, transferees and assigns. Without limiting the generality of the foregoing clause (iv), the Mortgagee may without notice to the Grantor assign or otherwise transfer the Note held by it and/or its rights hereunder or under the Note to any other person or entity, and such other person or entity shall thereupon become vested with all the benefits in respect thereof granted to the Mortgagee herein or otherwise, subject, however, to the provisions hereof. Upon the indefeasible payment and performance in full of all of the Obligations, the lien and security interest granted hereby shall terminate and all rights to the Collateral shall revert to the Grantor. Upon any such termination, the Mortgagee will, at the Grantor’s expense, execute and deliver to the Grantor an appropriate instrument evidencing such termination.

SECTION 5.4 Governing Law; Jurisdiction. This Mortgage shall be governed by and construed in accordance with the laws of the State of New York, except to the extent that the law of another jurisdiction may be mandatorily applicable to proceedings taken for the enforcement of the rights and remedies of the Mortgagee hereunder, provided that any such rights or remedies which shall be valid under the laws of such other jurisdiction shall not be affected by any invalidity thereof under the laws of the State of New York. Without limiting the right of the Mortgagee to bring any action or proceeding against the Grantor or against property of the Grantor arising out of or relating to this Mortgage (an “Action”) in any jurisdiction where such property is located, each of the Grantor and the Mortgagee hereby irrevocably submits to the non-exclusive jurisdiction of any New York State or Federal Court sitting in New York City. The Grantor hereby irrevocably waives, to the fullest extent it may effectively do so, the defense of an inconvenient forum to the maintenance of any Action in any jurisdiction and any right, claim or defense of any immunity on the basis of sovereignty or otherwise which the Grantor may have in connection with, arising out of or relating to this Mortgage. The Grantor hereby irrevocably appoints and designates CT CORPORATION SYSTEM located in New York, New York (“CT Corp.”) as its duly authorized agent for service of legal process and agrees that the summons and complaint or any other process in any Action in any jurisdiction may be served by registered or certified mail addressed to any of the addresses set forth below or by hand delivery

to a person of suitable age and discretion at any of the addresses set forth below. Such service will be complete on the date such process is so delivered. The Grantor may also be served in any other manner permitted by applicable law. Nothing contained in this Section 5.4 shall be interpreted to prohibit any of the Mortgagee or the Grantor from bringing an action against the Registrar of the International Registry in the Republic of Ireland.

SECTION 5.5 Severability. The invalidity of any one or more of the provisions of this Mortgage shall not affect the remaining provisions of this Mortgage, or operate to render this Mortgage invalid or to impair the lien and security interest of this Mortgage on all or the major portion of the property intended to be mortgaged hereunder, this Mortgage shall be construed as if such provisions had not been contained herein.

SECTION 5.6 Counterparts. This Mortgage may be executed in one or more counterparts which when signed by all the parties hereto shall be deemed to constitute a complete fully executed original document for all purposes.

SECTION 5.7 Effectiveness. With respect to the representations contained herein, the Grantor shall be construed as representing as to only itself.

SECTION 5.8 Further Assurances. The Grantor agrees from time to time within twenty (20) days of request by Mortgagee to do and perform such other and further acts and execute and deliver any and all such instruments as may be required by applicable law or reasonably requested by the Mortgagee to establish, maintain or protect the rights and remedies of the Mortgagee or to carry out and effect the intent and purpose of this Mortgage.
