	6.2.1	The
                                            Buyer or its duly authorized representatives (the “Buyer’s Inspector(s)”)
                                            shall be entitled to inspect the manufacture of the Airframe and all materials and parts
                                            obtained by the Seller (and its subcontractors) for the manufacture of the Airframe, attend
                                            inspection presentations and have access to the relevant logbooks (each an “Inspection”).
                                            The Seller will provide the Buyer reasonable notice of the start of each Inspection.
                                            Each Inspection shall be subject to the following terms and conditions;

 

		(i)	any Inspection shall be conducted pursuant
                                            to the Seller’s system of inspection and the relevant Seller procedures, as developed

		(iii)	any Inspection and any related discussions
                                            with the Seller and other relevant personnel by the Buyer’s Inspector(s) shall be at
                                            reasonable times during business hours and shall take place in the presence of the relevant
                                            inspection department personnel of the Seller;

 

		(iv)	the Inspections shall be performed in a
                                            manner not to unduly delay or hinder the manufacture or assembly of the Aircraft or the performance

	7	CERTIFICATION

 

Except
as set forth in this Clause 7, the Seller shall not be required to obtain any certificate or approval with respect to the Aircraft.
If any certificate identified in this Agreement, or use thereof, becomes ineffective or otherwise is no longer effective, withdrawn or
superseded after execution of this Agreement, then any reference to such certificate in this Agreement will be deemed to be a reference
to any other certificate or instrument issued by the applicable Aviation Authority that replaces or otherwise corresponds to such certificate.

 

		7.1	Type Certification

 

The Seller shall obtain or cause to be
obtained a type certificate for each type of Aircraft issued by each of the EASA and the FAA in the transport category (the “Type
Certificate”) prior to Delivery of the first Aircraft of such type, in a manner that allows the issuance of the Export Certificate
of Airworthiness for each Aircraft.

 

		7.2	Export Certificate of Airworthiness 

 

Subject to the provisions of Clause 7.3,
the Seller shall cause each Aircraft to be delivered to the Buyer with an Export Certificate of Airworthiness (without any limitation
or restriction, unless otherwise agreed between the parties) and in a condition enabling the Buyer (or an eligible person selected by
the Buyer, if the Buyer so elects, which election shall be notified to the Seller in writing) to obtain at the time of Delivery a Standard
Airworthiness Certificate issued pursuant to Part 21 of the US Federal Aviation Regulations and a Certificate of Sanitary Construction
issued by the U.S. Public Health Service of the Food and Drug Administration. However, the Seller shall have no obligation to make and
shall not be responsible for any costs of alterations or modifications to such Aircraft to enable such Aircraft to meet FAA or U.S. Department
of Transportation requirements that arise solely due to specific operation requirements on the Buyer’s specific routes, whether
before, at or after Delivery of any Aircraft.

 

If the FAA requires additional or modified
data before the issuance of the Export Certificate of Airworthiness, the Seller shall provide such data or implement the required modification
to the data, in either case, at the Seller’s cost.

 

		7.3	Specification Changes before Aircraft Ready
                                            for Delivery

 
	7.3.1	If, any time before the date on which any Aircraft
    is Ready for Delivery, any law, rule, directive, order or regulation is enacted, promulgated, becomes effective and/or an interpretation
    of any law, rule, directive, order or regulation is issued by the EASA or FAA that requires any change to the applicable Specification
    for the purposes of obtaining the Export Certificate of Airworthiness or the Standard Airworthiness Certificate referred to in Clause
    7.2 (a “Change in Law”), the Seller shall make the required change to comply with such Change in Law and, if applicable,
    the parties hereto shall execute an SCN or MSCN pursuant to Clause 2.2.

		7.3.2	The Seller shall as far as practicable, without
                                            prejudice to Clause 7.3.3 (ii), take into account the information available to it concerning
                                            any proposed law, rule, directive, order or regulation or interpretation that could become
                                            a Change in Law, in order to minimize the costs of changes to the applicable Specifications
                                            as a result of such proposed law, rule, directive, order, regulation or interpretation becoming
                                            effective before the date on which the applicable Aircraft is Ready for Delivery.

 

		7.3.3	The cost of implementing the required modifications
                                            referred to in Clause 7.3.1 shall be:

 

***

 

		7.3.4	Notwithstanding the provisions of Clause 7.3.3,
                                            ***.

 

 

		7.4	Specification Changes after Aircraft Ready
                                            For Delivery

 

Nothing in Clause 7.3 shall require the
Seller to make any changes or modifications to, or to make any payments or take any other action with respect to, any Aircraft after
it is Ready for Delivery before the compliance date of any law or regulation referred to in Clause 7.3. Any such changes or modifications
made to an Aircraft after it is Ready for Delivery shall be at the ***.

	8	TECHNICAL ACCEPTANCE

 

		8.1	Technical Acceptance
                                            Process

 

		8.1.1	Prior
                                            to Delivery, each Aircraft shall undergo a technical acceptance process developed by the
                                            Seller that demonstrates the satisfactory functioning of the Aircraft in accordance with
                                            the Specification (the “Technical Acceptance Process”). Completion of
                                            the Technical Acceptance Process shall demonstrate the satisfactory functioning of such Aircraft
                                            and shall be deemed to demonstrate compliance with the Specification. Should it be established
                                            that such Aircraft does not comply with the Technical Acceptance Process requirements, the
                                            Seller shall without hindrance from the Buyer carry out, at the Seller’s expense, any
                                            necessary changes to correct such non-compliance and, as soon as practicable thereafter,
                                            resubmit such Aircraft to such further Technical Acceptance Process as is necessary to demonstrate
                                            the elimination of the non-compliance and complete the Technical Acceptance Process (and
                                            for the avoidance of doubt, to the extent that the non-compliance relates to matters requiring
                                            an additional flight, then such further Technical Acceptance Process shall include such additional
                                            flight). The Buyer will be entitled to request that additional demonstrations be performed
                                            during the Technical Acceptance Process, and the Seller will consider such request in good
                                            faith. During the Technical Acceptance Process, the Buyer’s Inspector(s) shall
                                            be entitled to raise any concerns with respect to any non-compliance of the Aircraft with
                                            the Technical Acceptance Process requirements and the seller shall advise the Buyer of the
                                            actions it has taken to rectify such non-compliance. Any agreements between the Buyer and
                                            the Seller with respect to any non-compliance issues demonstrated during the Technical Acceptance
                                            Process will be documented in a separate written agreement. There shall be no duplicate remedies
                                            available to the Buyer with respect to any such non-compliance issues demonstrated during
                                            the Technical Acceptance Process set forth in such separate written agreement and this Agreement.

 

		8.1.2	The Technical Acceptance
                                            Process shall:

 

		(i)	commence
                                            on a date notified by the Seller to the Buyer, subject to Clause 9.1.3. In the event
                                            an Aircraft fails any Technical Acceptance Process, any resubmission of such Aircraft to
                                            further Technical Acceptance Process shall commence, and the Seller shall notify the Buyer
                                            of such commencement, as quickly as practicable following such failure;

 

		(ii)	take place at the
                                            Delivery Location;

 

		(iii)	be carried out
                                            by the personnel of the Seller; and

 

		(iv)	include an engine
                                            run, ground checks, static tests and a technical acceptance flight, conducted at the Seller’s
                                            expense, that shall not be less than *** and may not *** unless necessary to complete the
                                            Technical Acceptance Process (the “Technical Acceptance Flight”). It is
                                            understood by the parties that the content of the Technical Acceptance Process may evolve
                                            in the future, however it shall always include a Technical Acceptance Flight.

                                            Technical Acceptance Process.

 

		8.2.2	If the Buyer elects to attend the Technical
                                            Acceptance Process, the Buyer:

 

		(i)	shall comply with
                                            the reasonable requirements of the Seller, with the intention of completing the Technical
                                            Acceptance Process within ***;

 

		(ii)	may have a maximum
                                            of *** of its representatives (no more than *** of whom shall have access to the cockpit
                                            at any one time) accompany the Seller’s representatives on the Technical Acceptance
                                            Flight, during which the Buyer’s representatives shall comply with the instructions
                                            of the Seller’s representatives; and

 

		(iii)	***                                            

 

		8.2.3	If the Buyer except in good faith for legitimate
                                            reasons beyond the Buyer’s control, does not attend or fails to cooperate in the Technical
                                            Acceptance Process, the Seller shall be entitled to complete the Technical Acceptance Process
                                            and the Buyer shall be deemed to have accepted that the Technical Acceptance Process has
                                            been completed, in all respects, and the Seller will furnish such data with respect to such
                                            tests as the Buyer may reasonably request.

 

		8.3	Certificate of Acceptance

 

Following completion of the Technical
Acceptance Process, the Buyer shall, on or before the Delivery Date, execute and deliver to the Seller a certificate of acceptance in
respect of the applicable Aircraft in the form of Exhibit D (the “Certificate of Acceptance”).

 

		8.4	Finality of Acceptance

 

The Buyer’s execution of the Certificate
of Acceptance for the applicable Aircraft, and the parties execution of any written agreement referenced in Clause 8.1.1, shall constitute
waiver by the Buyer of any right it may have, under the Uniform Commercial Code as adopted by the State of New York or otherwise, to
revoke acceptance of such Aircraft for any reason, whether known or unknown to the Buyer at the time of acceptance.

		8.6	Aircraft Utilization

 

		8.6.1	The Seller shall, without payment or other
                                            liability, be entitled to use any Aircraft before its Delivery solely as may be necessary

                                            Authority of the Delivery Location for the purpose of exporting each Aircraft. If
                                            approval from such Aviation Authority is delayed for any reason not attributable to the Buyer,
                                            such that any Aircraft cannot be exported on the date of Delivery thereof, then the Seller,

of the European Community or of any national, Federal, State, municipal or other governmental department, commission, board, bureau,
agency, court or instrumentality, domestic or foreign; governmental priorities, regulations or orders affecting allocation of materials,
facilities or a completed Aircraft; war, civil war or warlike operations, terrorism, insurrection or riots; failure of transportation;
strikes or labor disputes causing cessation, slow down or interruption of work; delay in obtaining any airworthiness or type certification;
(ii) inability after due and timely diligence to procure materials, accessories, equipment or parts, or the failure of a subcontractor
or supplier to furnish materials, components, accessories, equipment or parts, in each case, if caused by events set forth in

		(iv)	the Seller shall use commercially reasonable
                                            efforts to minimize the duration of such Excusable Delay; and

 
	 	(v)	the Seller shall as soon as practicable after the removal
    of the cause of such Excusable Delay resume performance of its obligations under this Agreement and in particular shall notify the

		12	WARRANTIES AND SERVICE
                                            LIFE POLICY

 

		12.1	Warranty

 

		12.1.1	Nature of Warranty

 

Subject to the limitations and conditions
hereinafter provided, and except as provided in Clause 12.1.2, the Seller warrants to the Buyer that the Aircraft and each Warranted
Part will at the time of Delivery to the Buyer be free from defects:

 

		(i)	in material,

 

		(ii)	in workmanship, including, without limitation,
                                            processes of manufacture,

 

		(iii)	in design (including, without limitation,
                                            selection of materials) having regard to the State of the Art at the date of such design,
                                            and

 

		(iv)	arising from failure to conform to the
                                            Specification, except as to those portions of the Specification that are expressly stated
                                            in the Specification to be estimates or approximations or design aims.

 

For the purpose of this Agreement, the
term Warranted Part will mean any Seller proprietary component, equipment, software, accessory or part, that (a) is installed
on an Aircraft at Delivery, (b) is manufactured to the detailed design of the Seller or a subcontractor of the Seller and (c) bears a
Seller’s part number. Software that is installed on or embedded within a Warranted Part shall be deemed to be a component of such
Warranted Part.

 

		12.1.2	Exclusions

 

The warranties set forth in Clause 12.1.1
will not apply to Buyer Furnished Equipment, Propulsion Systems, or to any component, accessory, equipment or part purchased by the Buyer
that is not a Warranted Part, provided, however, that:

 

		(i)	any defect in the Seller’s workmanship
                                            in respect of the installation of such items in the Aircraft, including any failure by the
                                            Seller to conform to the installation instructions of the manufacturers of such items that
                                            invalidates any applicable warranty from such manufacturers, will constitute a defect in
                                            workmanship for the purpose of this Clause 12.1 and be covered by the warranty set forth
                                            in Clause 12.1.1(ii), and

 

		(ii)	any defect inherent in the Seller’s
                                            design of the installation, considering the State of the Art at the date of such design,
                                            that impairs the use of such items will constitute a defect in design for the purposes of
                                            this Clause 12.1 and be covered by the warranty set forth in Clause 12.1.1(iii).

                                            obligation and liability under Clauses 12.1.1 and 12.1.2 are limited to, at the Seller’s
                                            expense and option, the repair, replacement or correction (to include, in the case of software,
                                            supply of a comparable product with equivalent function) of any defective Warranted Part.
                                            The Seller may elect to effect such repair, replacement or correction by supplying modification
                                            kits designed to rectify the defect
                                            *** of such Warranted Part multiplied by the In-house Warranty Labor Rate. The Seller may alternatively
                                            furnish a credit to the Buyer for the future purchase of Goods and Services equal to the
                                            price at which the Buyer is then entitled to acquire a replacement for the defective Warranted
                                            Part. ***

 

		12.1.4.2	If the Seller corrects a defect covered
                                            by Clause 12.1.1(iii) that becomes apparent within the Warranty Period, on the Buyer’s
                                            written request the Seller will correct any such defect of the same type in any Aircraft
                                            that has not already been delivered to the Buyer. The Seller will not be responsible for,
                                            nor deemed to be in default on account of any delay in Delivery of any Aircraft or otherwise,
                                            in respect of performance of this Agreement, due to the Seller's undertaking to make such
                                            correction. Alternatively, the Buyer and the Seller may agree to deliver such Aircraft with
                                            subsequent correction of the defect by the Buyer at the Seller's expense, or the Buyer may
                                            elect to accept Delivery and thereafter file a Warranty Claim as though the defect had become
                                            apparent immediately after Delivery of such Aircraft.

		12.1.9	Warranty Transferability

 

Notwithstanding the
provisions of Clause 21.1, the warranties provided for in this Clause 12.1 for any Warranted Part will accrue to the benefit of any airline
in revenue service other than the Buyer, if the Warranted Part enters into the possession of any such airline as a result of a pooling
agreement between such airline and the Buyer, in accordance with the terms and subject to the limitations and exclusions of the foregoing
warranties and to applicable laws or regulations.

 

		12.1.9.1	Warranty for Corrected, Replacement
                                            or Repaired Warranted Parts

 

Whenever any
Warranted Part that contains a defect for which the Seller is liable under this Clause 12.1 has been corrected, repaired or replaced
pursuant to the terms hereof, the period of the Seller’s warranty with respect to such corrected, repaired or replacement
Warranted Part will be the remaining portion of the original warranty in respect of such corrected, repaired or replaced Warranted
Part ***. If a defect is attributable to a defective repair or replacement by the Buyer, a Warranty Claim with respect to such
defect will be rejected, notwithstanding any subsequent correction or repair, and will immediately terminate the remaining
warranties under this Clause 12.1 in respect of the affected Warranted Part.

		(i)	The Buyer maintains log books and other
                                            historical records with respect to such Item adequately to enable the Seller to determine
                                            whether the alleged Failure is covered by this Service Life Policy and, if so, to define
                                            the portion of the cost to be borne by the Seller in accordance with Clause 12.2.3.

 

		(ii)	The Buyer complies with the conditions
                                            of Clause 12.1.10.

                                            Seller. Such programs will be, to the extent possible, compatible with the Buyer’s
                                            operational requirements and will be carried out at the Buyer’s expense, reports relating

                                            or defect in such Item to the Seller *** after such breakage or defect becomes apparent to
                                            the Buyer, whether or not the breakage or defect can reasonably be expected to occur in any
                                            other Aircraft, and the Buyer provides the Seller with sufficient detail about the breakage
                                            or defect to enable the Seller to determine whether said breakage or defect is subject to
                                            this Service Life Policy.

 

		12.2.4.3	Except as otherwise provided in this Clause

                                            be subject to the terms and conditions of, Clause 12.1.6. All claims under this Service Life
                                            Policy will include all information reasonably available to the Buyer regarding significant
                                            incidents relating to the relevant Aircraft.

 

		12.2.4.4	If the Seller has issued a Service Bulletin
                                            modification applicable to an Aircraft, the purpose of which is to avoid a Failure, the Seller

                                            pro rata formula established by the Seller. If such a kit is so offered to the Buyer, then,

                                            Policies

 

		12.3.1	Seller’s Support

 

Before Delivery of
the first Aircraft, the Seller will provide the Buyer with the warranties and, where applicable, service life policies that the Seller
has obtained pursuant to the Supplier Product Support Agreements, such that the Buyer is authorized, to the full extent permitted in
the applicable Supplier Product Support Agreements, to directly enforce such warranties and service life policies against any applicable
Suppliers. Upon the Buyer’s written request, the Seller shall provide reasonable assistance to the Buyer regarding the enforcement
of such warranties and services life policies.

 

		12.3.2	Supplier’s Default

 

		12.3.2.1	If any Supplier under any warranty referred
                                            to in Clause 12.3.1 defaults in the performance of any material obligation under such warranty
                                            with respect to a Supplier Part and the Buyer submits reasonable evidence, within a reasonable
                                            time, that such default has occurred, then Clause 12.1 of this Agreement will apply to the
                                            extent it would have applied had such Supplier Part been a Warranted Part, except that the

		12.3.2.2	If any Supplier under any Supplier service
                                            life policy referred to in to Clause 12.3.1 defaults in the performance of any material obligation
                                            under such service life policy, and (i) the Buyer has used its reasonable efforts to resolve
                                            the applicable issue under such service life policy, and (ii) the Buyer submits within reasonable
                                            time to the Seller reasonable evidence that such default has occurred, then Clause 12.2 of
                                            this Agreement will apply to the extent the same would have applied had such Supplier Part
                                            been an Item, except that the Supplier’s service life policy period as indicated in

                                            and the Buyer will provide reasonable assistance to enable the Seller to enforce the rights
                                            so assigned.

 

		12.4	Interface Commitment

 

		12.4.1	Interface Problem

 

If the Buyer experiences
any technical problem in the operation of an Aircraft or its systems due to a malfunction, the cause of which, after due and reasonable
investigation, is not readily identifiable by the Buyer, but which the Buyer reasonably believes to be attributable to the design characteristics
of one or more components of the Aircraft (an “Interface Problem”), the Seller will, if requested by the Buyer, and without
additional charge to the Buyer, except for *** transportation of the Seller’s or its designee’s personnel to the
Buyer’s facilities, promptly conduct or have conducted an investigation and analysis of such problem to determine, if possible,
the cause or causes of the problem and to recommend such corrective action as may be feasible. The Buyer will furnish to the Seller all
data and information in the Buyer’s possession relevant to the Interface Problem and will cooperate with the Seller in the conduct
of the Seller’s investigations and such tests as may be required. At the conclusion of such investigation the Seller will promptly
advise the Buyer in writing of the Seller’s opinion as to the cause or causes of the Interface Problem and the Seller’s recommendations
as to corrective action.

 

		12.4.2	Seller’s Responsibility

 

If the Seller determines
that the Interface Problem is primarily attributable to the design or workmanship of a Warranted Part, the Seller will, at the Buyer’s
request, promptly correct the design or processes of manufacture of such Warranted Part pursuant to the terms and conditions of Clause
12.1.

 

		12.4.3	Supplier’s Responsibility

 

If the Seller determines
that the Interface Problem is primarily attributable to the design of any Supplier Part, the Seller will at the Buyer’s request,
*** and make reasonable efforts to find a solution satisfactory to the Buyer,
including assisting the Buyer with processing and enforcing any warranty claim against the applicable Suppliers.

		12.4.4	Joint Responsibility

 

If the Seller
determines that the Interface Problem is attributable partially to the design or workmanship of a Warranted Part and partially to
the design or workmanship of any Supplier Part, the Seller will, if requested by the Buyer, *** and make reasonable efforts to find
a solution satisfactory to the Buyer. The Seller will promptly advise the Buyer of any corrective action proposed by the Seller and
any such Supplier. Such proposal will be consistent with any then existing obligations of the Seller hereunder and of any such
Supplier to the Buyer. Such corrective action, unless reasonably rejected by the Buyer, will constitute full satisfaction of any
claim the Buyer may have against either the Seller or any such Supplier with respect to such Interface Problem.

 

		12.4.5	General

 

		12.4.5.1	All requests under this Clause 12.4 will

                                            not expressly set forth elsewhere in this Agreement.

 

		12.4.5.3	All reports, recommendations, data and
                                            other documents furnished by the Seller to the Buyer pursuant to this Clause 12.4 will be

be in monetary damages limited to the amount the Buyer expends in procuring a correction or replacement for any covered part subject
to a defect or nonperformance covered by this Clause 12, and the Buyer will not have any right to require specific performance by the
Seller.

		(ii)	this Agreement, and in particular this
                                            Clause 12, has been the subject of discussion and negotiation and is fully understood by

		(iii)	the price of the Aircraft and the other
                                            mutual agreements of the Buyer set forth in this Agreement were arrived at in consideration
                                            of, inter alia, the provisions of this Clause 12, specifically including the Exclusivity

                                            members of The Berne Union and recognize software as a “work” under the Berne
                                            Convention.

 

	13.1.2	Clause 13.1.1 shall not apply to

                                  or by a settlement arrived at among the claimant, the Seller and the Buyer), the Seller shall as soon
                                  as possible and at its expense either:

 

		(i)	procure for the Buyer the right to use the
                                            affected Airframe, part or software free of charge; or

 

		(ii)	replace the infringing part or software

                                            be merged or consolidated, provided that:

 

		(i)	the assigning party shall provide notice
                                            thereof to the non-assigning party, such notice to contain a summary of the material terms
                                            of the transaction, *** following the public announcement thereof (or if no such announcement,
                                            from the completion thereof);

 

		(ii)	if the assigning party is the Buyer, the
                                            surviving or acquiring entity shall execute an assumption agreement in form and substance
                                            reasonably acceptable to the Seller, agreeing to assume all of the Buyer's obligations under
                                            this Agreement;

 

		(iii)	if the assigning party is the Buyer, the
                                            entity that will take delivery of any Aircraft following the consummation of the transaction
                                            will hold either an FAA Part 121 (or successor provision) air carrier operating certificate,
                                            or an EASA air carrier operating certificate; at the time of any such delivery;

 

		(iv)	if the assigning party is the Buyer, if
                                            the entity that would result from such transaction, or that would acquire all or substantially
                                            all of the Buyer’s assets (including, for the purposes of clarity, this Agreement)
                                            in such transaction, is a direct competitor of the Seller or is an Affiliate of any such
                                            direct competitor, then such assignment shall require the Seller’s prior written consent;

 

		(v)	if
                                            the assigning party is the Buyer, if the surviving or acquiring entity has an existing purchase
                                            agreement for aircraft manufactured by the Seller of the same type as the Aircraft, the Buyer
                                            and Seller shall discuss in good faith the potential rescheduling of the consolidated order
                                            of such surviving or acquiring entity for such aircraft (including the Aircraft) in order
                                            to optimize the delivery schedule of such consolidated order.

		21.2.2	If, at the time of, and immediately following
                                            the consummation of, the transaction, a Termination Event exists or shall have occurred and
                                            be continuing, such transaction shall not prejudice any rights that the non-assigning party
                                            may have in respect thereof.

 

If either party enters into an assignment
that does not comply with the provisions of Clause 21.2.1, such assignment will be null and void and the non-assigning party will be
entitled to deem such attempted assignment as a Termination Event and the terms and conditions of this Clause 20 will apply.

 

		21.3	Designations by Seller

 

The Seller may at any time by notice
to the Buyer designate facilities or personnel of the Seller, AACS or any other Affiliate of the Seller at which or by whom the services
to be performed under this Agreement shall be performed. Notwithstanding such designation, the Seller shall remain ultimately responsible
for fulfilment of all obligations undertaken by the Seller in this Agreement.

 

		21.4	Transfer of Rights and Obligations upon
                                            Reorganization

 

In the event that the Seller is subject
to a corporate restructuring having as its object the transfer of, or succession by operation of law in, all or a substantial part of
its assets and liabilities, rights and obligations, including those existing under this Agreement, to a person (the “Successor”)
that is an Affiliate of the Seller at the time of that restructuring, for the purpose of the Successor carrying on the business carried
on by the Seller at the time of the restructuring, such restructuring shall be completed without consent of the Buyer following notification
by the Seller to the Buyer in writing. The Buyer recognizes that succession of the Successor to the Agreement by operation of law that
is valid under the law pursuant to which that succession occurs shall be binding upon the Buyer.

 

		21.5	Assignments for Delivery Financing

 

Prior to
Delivery, the Buyer will not assign, novate, lease or transfer the Aircraft, or contract to do so, without the Seller's written consent.
However, the Buyer may at the time of Delivery, subject to the Seller's approval of form and substance of the assignment documentation,
which approval will not be unreasonably withheld, assign certain of its rights hereunder, with respect to any Aircraft for the purpose
of causing the Aircraft at the time of Delivery to be subjected to an equipment trust, conditional sale, lien or other arrangement
for the financing by the Buyer of such Aircraft, provided (i) any third party participating in such equipment trust, conditional sale
or other financing arrangement has met Seller’s reasonable due diligence procedures including “know your customer”
requirements of the Seller and (ii) the Buyer simultaneously therewith agrees to a long-term lease from the assignee of such Aircraft
as to which such assignment is applicable; provided, however, that no such action will subject the Seller to any liability which it would
not otherwise be subject to hereunder, or require the Seller to divest itself of title to or possession of any such Aircraft until Delivery
thereof and payment therefor as provided in this Agreement. No action by the Buyer or the Seller under this Clause 21.5 will require
the Seller to divest itself of title to or possession of such Aircraft until Delivery and payment therefor as provided in this Agreement.

In the event of the resale of any Aircraft,
the Buyer's rights with respect to warranties and support and services applicable to such Aircraft under this Agreement will inure to
the benefit of such purchaser, but only (i) to the extent such rights exist or remain at the time of such resale and (ii) pursuant to
an assignment agreement in form and substance acceptable to the Seller, which approval will not be unreasonably withheld and (iii) should
the Seller have any obligations towards the subsequent new operator pursuant to such resale, such new operator has met Seller’s
reasonable due diligence procedures including “know your customer” requirements of the Seller.

                                            Eighth Avenue, New York, NY 10011, as its legal agent and attorney-in-fact upon whom all
                                            processes against the Seller in any suit, action or proceeding in respect of any matter as
                                            to which it has submitted to jurisdiction under Clause 22.6 may be served with the same effect
                                            as if the Seller were a corporation organized under the laws of the State of New York and
                                            had lawfully been served with such process in such state.

 

	22.6.2	The assumption in Clause 22.6.1 made for the purpose
                                            of effecting the service of process shall not affect any assertion of diversity by either
                                            party hereto initiating a proceeding in the New York Federal Courts or seeking transfer to
                                            the New York Federal Courts on the basis of diversity.

 

	22.6.3	Service of process in any suit, action or proceeding
                                            in respect of any matter as to which the Seller or the Buyer has submitted to jurisdiction
                                            under Clause 22.6 (i) may be made on the Seller by delivery of the same personally or by
                                            dispatching the same via Federal Express, UPS, or similar international air courier service
                                            prepaid to, CT Corporation, New York City offices as agent for the Seller, it being agreed
                                            that service upon CT Corporation shall constitute valid service upon the Seller or by any
                                            other method authorized by the laws of the State of New York, and (ii) may be made on the

	22.10	Confidentiality

 

	22.10.1	This Agreement and all reports or other data
                                            exchanged by the parties hereunder (including but in no way limited to aircraft or Aircraft
                                            pricing) shall be deemed to be “Confidential Information”. For the purposes
                                            of this Clause 22.10, a “Disclosing Party” is the party who discloses
                                            Confidential Information pursuant to this Agreement and a “Recipient”
                                            is the party who receives Confidential Information pursuant to this Agreement.

 

	22.10.2	The Recipient will, and will cause its employee(s),
                                            and any other person who obtains any part of the Confidential Information through the Recipient,
                                            to preserve the confidentiality of the Confidential Information. Except as provided in this
                                            Agreement, the Recipient shall not:

 

		(i)	copy,
                                            reproduce, distribute or disclose (whether oral or written) to any person, firm, entity or
                                            corporation any of the Confidential Information, or any facts related thereto, other than
                                            on a need-to-know basis, or

 

		(ii)	permit
                                            any third party to have access to such Confidential Information, or

 

		(iii)	use
                                            the Confidential Information for any purpose other than the purpose for which it is provided.

	22.10.3	The Recipient may provide the Confidential Information
                                            to its employees, officers, directors, contractors, counsel, auditors and Affiliates (each
                                            such person, an “Individual”), provided such Individuals (i) need to know
                                            the Confidential Information for such Recipient’s performance under the Agreement,
                                            the operation of the party’s business, or for any other purpose specifically agreed
                                            by the parties and (ii) are informed of this Agreement; and provided also that the Recipient
                                            remains fully liable to the Disclosing Party for any disclosure of Confidential Information
                                            by any such Individuals that would constitute a breach of this Clause 22.10 had such Individual
                                            been party to this Agreement.

 

	22.10.4	If a party is required to make any filing with
                                            any governmental agency that involves disclosure of Confidential Information, it will give
                                            the other party prior notice of such filing and an opportunity to review and comment upon
                                            any planned disclosures. The Recipient will act to limit the scope of such disclosures to
                                            the extent legally permissible.

 

	22.10.5	If either party is required by any judicial or
                                            governmental proceeding to disclose any Confidential Information, such party will give the
                                            other party prompt notice of such request, and such other party may seek an appropriate protective
                                            order. If, in the absence of a protective order, a party is nonetheless advised by counsel
                                            that disclosure of the Confidential Information is required by law, such party may disclose
                                            such Confidential Information without liability hereunder. A party may disclose all or any
                                            portion of the Confidential Information without liability (i) as required by law or regulation,
                                            (ii) without prejudice to Clause 22.10.4, as requested by any bank regulatory body or other
                                            governmental authority or any representative thereof with legal authority to compel disclosure,
                                            or (iii) in any action or proceeding or arising out of or related to this Agreement among
                                            the parties hereto, to the extent and only to the extent such disclosure is necessary for
                                            the parties to defend such action.

 

	22.10.6	The term Confidential Information does not include
                                            any information that, as demonstrated through production of credible evidence:

 

		(i)	becomes
                                            or has become generally available to the public other than as a result of violation of this
                                            Clause 22.10;

 

		(ii)	has
                                            been available on a non-confidential basis prior to its disclosure hereunder;

 

		(iii)	is
                                            or has been developed or acquired independently by personnel of the Recipient having no substantive
                                            knowledge of the Confidential Information; or

 

		(iv)	becomes
                                            available on a non-confidential basis from a third party source.

 

	22.10.7	The parties specifically acknowledge that an
                                            action for damages may not be an adequate remedy for a breach by the Recipient of the terms
                                            of this Clause 22.10, and that each party shall be entitled to pursue all remedies available
                                            to it in the event of such breach, including but not limited to, an action against the other
                                            party for equitable relief and emergency or injunctive relief to prevent further or continuing
                                            breach.

 

	22.10.8	The provisions of this Clause 22.10 will survive
                                            termination of the Agreement.

	22.11	Severability

 

Any provision of the Agreement determined
to be unlawful or unenforceable under applicable law applied by any court of competent jurisdiction shall, to the extent required by
such law, be deemed severed from the Agreement and rendered ineffective so far as is possible without modifying the remaining provisions.
Where, however, the provisions of any such applicable law may be waived, they are hereby waived by the parties hereto to the fullest
extent permitted by such law, with the result that the provisions of the Agreement shall be a valid and binding and enforceable in accordance
with their terms. The parties agree to replace, so far as practicable, any provision which is prohibited, unlawful or unenforceable with
another provision having substantially the same effect (in its legal and commercial content) as the replaced provision, but which is
not prohibited, unlawful or unenforceable. The invalidity in whole or in part of any provisions of the Agreement shall not void or affect
the validity of any other provision.

 

	22.12	Entire Agreement

 

This Agreement contains the entire agreement
between the parties with respect to the subject matter hereof and supersedes any previous understanding, commitments or representations
whatsoever, whether oral or written. This Agreement shall not be amended or modified except by an instrument in writing of even date
herewith or subsequent hereto executed by both parties or by their fully authorized representatives.

 

	22.13	Inconsistencies

 

In the event of any inconsistency between
the terms of this Agreement and the terms contained in either (i) the Specification, or (ii) any other Exhibit, in each such case the
terms of this Agreement shall prevail over the terms of the Specification or any other Exhibit. For the purpose of this Clause 22.13,
the term Agreement shall not include the Specification or any other Exhibit hereto.

 

	22.14	Language

 

All correspondence, documents and any
other written matters in connection with this Agreement shall be in English.
