CLAUSE
3    SPARE PARTS PROVISIONS    

	3.1
	Intent and Term

	3.1.1
	For
as long as ACA has one or more Aircraft in its fleet, IAE shall ensure that reasonably adequate supplies of Spare Parts are available for sale to ACA under this Contract.
[***]

	3.1.2
	For
so long as ACA has one or more Aircraft in its fleet, IAE will make available to ACA unused Vendor Parts for which direct supply arrangements between the manufacturers of such
Vendor Parts and ACA cannot be established. Except for the purposes of Initial Provisioning pursuant to Clause 3.3 below, ACA shall notify IAE in writing not less than
[***] months before scheduled delivery requested by ACA that ACA intends to purchase such Vendor Parts from IAE. [***] 

3.2    ATA Standards    

The
Parties shall comply with the requirements of ATA Specifications 2000 and 300, provided that the Parties shall be entitled to negotiate reasonable changes in those procedures or requirements of
the said specifications which, if complied with exactly, would result in an undue operating burden or unnecessary economic penalty. 

9

 

3.3    Initial Provisioning    

	3.3.1
	To
assist ACA's Initial Provisioning, IAE shall supply ACA with Initial Provisioning Data in accordance with ATA Specification 2000.

	3.3.2
	Details
of the format and precise nature of the said Initial Provisioning Data, including the applicable revision numbers of ATA Specification 2000, definition of Spare Parts
Categories, and Lead Times, and agreement on technical publications shall be agreed between the Parties at a preliminary meeting held for this purpose at a time and place to be agreed.

	The
Initial Provisioning Data shall cover all Spare Parts, including agreed Vendor Parts, which in IAE's opinion may be reasonably required for ACA's operation of the Engines.

	3.3.4
	Before
ACA places Initial Provisioning Orders, a conference shall be held for the review of Initial Provisioning Data supplied by IAE under Clause 3.3.1 above. This
conference shall be held as soon as possible to ensure delivery of necessary Spare Parts as described in the Initial Provisioning Data before the first Leased Aircraft delivery and shall be attended
by the personnel of each party directly responsible for Initial Provisioning. 

3.4    Change In Initial Provisioning Data    

IAE
shall, free of charge, progressively and promptly revise Initial Provisioning Data in accordance with ATA Specification 2000 to take into account any changes which may materially affect
provisioning decisions. 

3.5    Stocking of Spare Parts    

Within
a reasonable time following IAE's request, ACA shall provide IAE with information reasonably required to enable IAE to plan and organize the manufacture and stocking of Spare Parts. 

3.6    Lead Times    

	3.6.1
	Spare
Parts for Initial Provisioning shall be delivered on or before the dates specified in ACA's orders, provided that such dates comply with lead times and do not call for
delivery more than [***] before the scheduled date of delivery of the first Leased Aircraft to ACA and provided further that delivery of the total Initial Provisioning quantity
shall be effected in line with ACA's fleet build up and Aircraft utilization.

	3.6.2
	Except
as herein provided, replenishment Spare Parts shall be delivered within the Lead Time specified in the IAE Spare Parts Catalog, except for certain major Spare Parts which
shall be designated in Initial Provisioning Data as being available at prices and lead times to be quoted upon request.

	3.6.3
	If
any order for replenishment Spare Parts calls for a quantity materially in excess of ACA's normal requirements, IAE shall nevertheless use commercially reasonable efforts to
complete such order, provided, however, that IAE shall have the right to notify ACA and may request a special delivery schedule. If ACA confirms that the full quantity ordered is required, delivery of
the order shall be effected at delivery dates as agreed by the Parties and the Lead Times provided by this Clause 3.6 shall not apply.

	3.6.4
	In
the events described in Clauses 3.6.4.1 through 3.6.4.3 below, IAE shall use commercially reasonable efforts to deliver Spare Parts, including certain major Spare Parts referred
to in Clause 3.6.2 above, within the time limits specified by ACA. IAE will provide notice of the action to be taken on such order within the following time periods from IAE's receipt of such
notice and based on the type of order:

	3.7.1
	After
receipt of Initial Provisioning Data, ACA shall place its Initial Provisioning Orders in sufficient time to allow IAE to commence delivery prior to delivery of the first
Leased Aircraft. [***]

	3.7.2
	Subsequent
orders for Spare Parts shall be placed by ACA from time to time as ACA may deem appropriate. ACA shall endeavor to give IAE reasonable notice of any change in its
operation (including, but not limited to, changes in maintenance or overhaul arrangements) affecting its requirements of Spare Parts, including Vendor Parts.

	3.7.3
	IAE
shall promptly acknowledge receipt of each order for Spare Parts in accordance with ATA Specification 2000 procedure. Unless qualified, such acknowledgment, shall constitute an
acceptance of the order under the terms of this Contract.

	3.7.4
	If
IAE notifies ACA that certain low individual cost Spare Parts, such as bolts, nuts, washers and other similar items, are packed in standard package quantities (hereinafter called
"SPQs"), ACA's subsequent orders for such Spare Parts shall be for SPQs or multiples thereof.

	3.7.5
	Unless
ACA shall have specified "Total Quantity Required" on its orders, IAE shall be entitled to consider an order for inexpensive
Spare Parts complete if at least [***] of the quantity ordered is delivered [***]. For the purpose of this Clause the term "inexpensive" shall mean a
price listed in the IAE Spare Parts Catalog at less than Ten U.S. Dollars ($10) per unit, but shall be subject to change by IAE from time to time.

Service Bulletins when such modified Spare Parts (or Spare Parts introduced by a repair scheme) will become available for supply hereunder. Notification of such availability shall be given to ACA
before delivery of the modified Spare Part.

	3.8.2
	Modified
Spare Parts shall be substituted for Spare Parts ordered unless the modifications stated in Service Bulletins are considered by ACA to be unacceptable and ACA so states in

of pre-modified Spare Parts, at a price to be agreed but in no event greater than the then current catalogue price and with a delivery schedule to be agreed.

	3.8.3
	IAE
may supply at the expense of ACA a modification of any Spare Part ordered by ACA (including any additional Spare Part needed to ensure performance, weight, utility, durability,
interchangeability and intermixability, fuel burn, maintenance cost, and reliability), provided that the said modification has received the approval of the Certification Authority and has been
evidenced by issuance of a Service Bulletin. The delivery of such Spare Parts shall begin on dates indicated by Service Bulletin. The delivery schedule shall be agreed at the time when orders for
modifications are accepted by IAE. 

11

 

	3.8.4

CLAUSE
4    WARRANTIES, GUARANTEES AND LIABILITIES    

	4.1
	IAE
warrants to ACA that, at the time of delivery, the Supplies sold hereunder will be free of defects in material, workmanship (including without limitation process of manufacture)
and will conform in all material respects to applicable specifications. IAE's liability and ACA's remedies under this warranty are limited to the repair or replacement, at IAE's election, of Supplies
or parts thereof returned to IAE at the factory of manufacture which are shown to [***]have been defective; provided, that the defect shall have been discovered by ACA and ACA
has provided IAE with written notice of such defect not later than [***]. Transportation charges for the return of Supplies to IAE pursuant to this Clause 4.1 and their
reshipment to ACA and the risk of loss thereof will be borne by IAE only if the Supplies are returned in accordance with reasonable written shipping instructions from IAE and reasonably judged by IAE
to be defective.

	4.2
	In
addition, IAE grants and ACA accepts the following:

	4.2.1
	V2500
Engine and Parts Service Policy

	4.2.2

The
Service Policies, Warranties and Guarantees referred to in this Clause 4.2 are hereinafter called the "Warranties". The above Service
Policies, Warranties and Guarantees together form Exhibit D to this Contract. 

	4.3
	The
Parties agree that those of the Warranties set out in Clauses 4.2.1 and 4.2.2 above shall apply to any equipment which falls within the type of equipment covered by those
Warranties, which are manufactured, supplied or inspected by IAE howsoever and whenever (whether before, on or after 

14

 

the
date first above written) acquired by ACA from whatsoever source including but not limited to any V2500 aero engines and any associated equipment therefor, and any parts for such engines and
associated equipment which form part of any aircraft. 

	4.4
	Except
as otherwise provided in this Contract, the Warranties are personal to ACA and the obligations of IAE thereunder shall only apply insofar as ACA owns and operates the Supplies
covered thereunder, provided that ACA may fully assign the Warranties in accordance with Clause 6.7.1.

	4.5
	ACA
shall inform any entity to whom it intends to sell, lease, loan or otherwise dispose of any of the Supplies or equipment referred to in Clause 4.3 above that such entity
may obtain from IAE a direct warranty agreement incorporating those of the Warranties set out in Clauses 4.2.1 and 4.2.2. In the event such entity desires to obtain from IAE the benefits of any
remaining Warranties, ACA shall also use its reasonable endeavors to ensure that such entity shall enter into a direct warranty agreement with IAE prior to delivery of any of the Supplies or such
equipment to such entity.

	4.6
	The
Parties agree that the intent of the Warranties provided in Clause 4.2 is to provide specified benefits or remedies to ACA as a result of specified events. It is not the
intent, however, to duplicate benefits or remedies provided to ACA by IAE or another source (i.e., another equipment manufacturer or lessor) as a result of the same event or cause. Therefore,
notwithstanding the terms of the Warranties, if the terms of the Warranties should make duplicate benefits available to ACA from IAE or any third party, ACA may elect to receive the benefits under the
Warranties or under any other applicable guarantee, sales warranty, service policy or any special benefit of any kind as a result of the same event, but—to the degree ACA would enjoy
duplication of remedies—not both.

	4.7
	[***]

	4.8
	The
Parties agree that this Clause 4 has been the subject of discussion and negotiation, is fully understood by the Parties and the price of the Supplies and other mutual
agreements of the Parties set forth in this Contract are arrived at in consideration of:

	4.8.1
	the
express Warranties of IAE and ACA's rights thereunder; and

	4.8.2
	[***].

	4.9
	In
consideration for the benefits provided by IAE to ACA, including the Warranties set out in Clauses 4.2.1 and 4.2.2, ACA agrees [***]. 

CLAUSE
5    PRODUCT SUPPORT SERVICES    

	5.1
	IAE
will make available to ACA the Product Support Services described in Exhibit C to this Contract. Except when identified in such Exhibit C as being at additional cost
or as requiring separate contractual arrangements, such Product Support Services shall be supplied at no additional charge to ACA and subject to the provisions of this Contract. IAE may delegate the
performance of product support services to an affiliated company or any of IAE's current shareholders, including Pratt & Whitney, Rolls-Royce plc, MTU Aero Engines of Germany and Japanese Aero
Engines Corporation, or any of their affiliates or wholly-owned subsidiaries, or any future shareholder of IAE, although no such delegation will relieve IAE of its primary responsibility for the
performance of the same.

	5.2
	ACA
will provide to the IAE Customer Support Representative working at its facility, free of charge:

	(a)
	reasonable,
secure office accommodation including furniture and office equipment;

	(b)
	access
to telephone and facsimile; 

15

 

	(c)
	access
to such first-aid and emergency assistance as is customarily provided to ACA's own employees; and

	(d)
	[***]. 

ACA
further agrees that such customer support representative(s) will be entitled to all reasonable working benefits allowed pursuant to normal IAE practice, including but not limited to, leaves of
absence relating to vacation, holiday and sick time. IAE Customer Support representatives located throughout North America who are fully trained on all facets of V2500-A5 engine line
maintenance will be available to assist ACA as required when ACA's IAE Customer Support Representative is not available on site at ACA. 

CLAUSE
6    MISCELLANEOUS    

	6.1
	Delay in Delivery

	6.1.1
	If
IAE is hindered or prevented from delivering any of the Supplies within the time for delivery specified in this Contract (as such time may be extended pursuant to the provisions
of this Contract) by reason of an Excusable Delay, the time for delivery shall be extended by a period equal to the period for which delivery shall have been so hindered or prevented by such Excusable
Delay. Any other circumstance in which IAE is hindered or prevented from delivering any Supplies within the time for delivery specified in the Contract (as such time may be extended pursuant to the
provisions of this Contract) by reason of any cause other than an Excusable Delay shall be deemed an "Inexcusable Delay". 

Should
IAE delay delivery of any Firm Spare Engine by virtue of an Excusable Delay beyond the time for delivery specified in this Contract for a period of [***] or more, ACA
shall be entitled to refuse to take delivery of such item and shall be relieved of any future obligation to take delivery of such item from IAE on giving IAE notice in writing within
[***] after the expiration of such period of [***]. Should IAE delay delivery of any Firm Spare Engine by virtue of an Inexcusable Delay beyond the time
for delivery specified in this Contract for a period of [***] or more, ACA shall be entitled to refuse to take delivery of such item and shall be relieved of any future
obligation to take delivery of such item from IAE on giving IAE notice in writing within [***] after the expiration of such period of [***]. Upon
receipt of any such notice IAE shall be free from any obligation in respect of such item except that, if ACA refuses to take delivery as permitted hereunder of the last Firm Spare Engine to be
delivered to ACA, IAE shall refund to ACA any deposits made in respect of the purchase price of such delayed Firm Spare Engine. Where IAE must refund deposits to ACA due to delay as specified in this
Clause 6.1.1, and IAE has not provided a lease as set forth in clause 6.1.5 below, then IAE shall [***]. 

	6.1.2
	If,
by reason of any of the causes embraced by Clause 6.1.1 above, IAE is hindered or prevented from delivering any goods (which are the same as and include the Supplies) to
purchasers (including ACA) then IAE shall have the right to allocate in good faith such goods, as they become available, at its own discretion among all such purchasers [***]
and provided further, no such allocation will relieve IAE of any liability for delay in delivery of any Supplies to ACA resulting from such allocation.

	6.1.3
	Should
IAE delay delivery of any item of Supplies (other than Firm Spare Engines) beyond the time for delivery specified in this Contract (as such time may be extended pursuant to
the provisions of this Contract) as a result of an Excusable or Inexcusable Delay, then ACA may acquire any such Supplies from a source other than IAE ("Replacement
Supplies"), as provided for in Section 3 above. If ACA acquires Replacement Supplies pursuant to this section 6.1.3, ACA will have the right to notify IAE of its
cancellation of any pending order from IAE for the same Supplies without penalty. [***]. 

16

 

	6.1.4
	In
the event of an Excusable Delay, all prices of Supplies stated in the Contract subject to escalation shall be escalated at [***] calculated in accordance
with the IAE Escalation Formula set forth in Exhibit B-2 to this Contract from (a) the original scheduled delivery month for such Supplies in effect prior to the occurrence
of the Excusable Delay to (b) the actual delivery month of such Supplies. In the event of an Inexcusable Delay, all prices of Supplies stated in the Contract subject to escalation shall not be
subject to any additional escalation from (a) the original scheduled delivery month in effect prior to the occurrence of the Inexcusable Delay to (b) the actual delivery month of such
Supplies.

	6.1.5
	Should
IAE delay delivery of a Firm Spare Engine beyond the time of delivery specified in this Contract as a result of either an Excusable or Inexcusable Delay and if all of ACA's
V2500-A5 spare engines are being utilized to support the Firm Aircraft or are undergoing shop visits, IAE shall station a dedicated V2500-A5 lease engine of the same model type
and thrust as the delayed Firm Spare Engine ("Replacement Spare Engine") in the region of ACA's main base, Dulles, Virginia, to enable ACA to lease such
engine should ACA require an additional spare Engine to maintain the integrity of its flight schedule. For such a lease IAE will [***], however ACA will pay IAE's then
published provisioned hourly and cyclic charges associated with such lease engine. The form and structure of the engine lease described hereby shall be in the general form of the Standard Terms of
Business for Lease of V2500 Engines (the "STOBL") attached as Exhibit E, except that a security deposit shall not be required as provided for in Clause 10 of the STOBL. If
IAE fails to lease a Replacement Spare Engine to ACA pursuant to this section 6.1.5, then IAE shall promptly reimburse ACA for the amount of the [***] of any Engine
acquired by ACA in excess of the [***] if IAE had provided a Replacement Spare Engine.

	6.1.6
	[***]

	6.2
	Intellectual Property

	6.2.1
	IAE
shall, subject to the conditions set out in this Clause and as the sole liability of IAE with respect to the claims of intellectual property infringement described in this
Clause 6.2, indemnify, release, defend, and hold ACA (and its affiliates and their respective officers, directors, shareholders, members, employees, contractors and representatives) harmless
from and against any damages, costs, losses, liabilities, penalties, and expenses, including reasonable legal expenses resulting from or arising out of or in connection with any claim that the use of
any of the Supplies (or of any component, part, process, technical data, technology or software installed therein or supplied therewith) by ACA within any country in which at the date of such claim
the benefits of Article 27 of the Convention on International Civil Aviation of 7th December 1944 (The Chicago Convention) apply, infringes any patent, design, or model duly granted or
registered, or any copyright, [***], provided, however, that IAE shall not be liable to ACA for any consequential damage or any loss of use of Supplies or of the Aircraft in
which the Supplies may be incorporated arising as a result directly or indirectly of any such claim.

	6.2.2
	ACA
will give prompt notice in writing to IAE of any such claim whereupon IAE shall have the right at its own expense to assume the defense of or to dispose of or to settle such
claim in its sole discretion, [***]. ACA will give IAE all reasonable assistance (at IAE's expense) to defend such claim.

	6.2.3
	IAE
shall have the right to substitute for any allegedly infringing Supplies substantially equivalent non-infringing supplies, [***]. 

17

 

	6.2.4
	In
the event that the use of the Supplies is enjoined, IAE shall promptly, at its expense and option, either:

	6.2.4.1
	substitute
substantially equivalent non-infringing Supplies;

	6.2.4.2
	procure
for ACA the right to continue using the Supplies; or

	6.2.4.3
	modify
the Supplies as to make them non-infringing.

	6.2.5
	The
indemnity contained in Clause 6.2.1 above shall not apply to claims for infringement to the extent (i) Supplies are manufactured to the specific design
instructions of ACA; (ii) due to the manner or method in which any of the Supplies is installed in the Aircraft (except to the degree such installation is performed in accordance with IAE's
instructions) or (iii) any combination of any of the Supplies with any item or items other than Supplies.

	6.3
	Damages for Aircraft and/or Spare Engine Cancellations [***]

	6.3.1
	Damages

If
ACA (i) fails to take delivery of any of the Firm Aircraft or Firm Spare Engines pursuant to the schedule set forth in Exhibit B-1 hereto (as such may be modified or
supplemented pursuant to the terms of the Contract) or (ii) defers or delays (other than an Excusable or Inexcusable Delay) the delivery of any such Firm Aircraft or Firm Spare Engine in a
manner not permitted hereunder for a total period in [***] with respect to any such Aircraft or Spare Engine, [***]. 

Furthermore,
IAE and ACA agree [***]. 

	6.3.2
	[***]

[***].

	6.4
	Non-Disclosure and Non-Use

	6.4.1
	Subject
to Clause 6.4.3 below, both Parties agree not to disclose to any third party (other than professional advisers of such Party who agree to abide in advance by the
non-disclosure requirements set forth in this Clause 6.4) any Information which either Party acquires directly or indirectly from the other Party and agree not to use the same other
than for the purpose for which it was disclosed without the written approval of the other Party. The expression "Information" in this
Clause 6.4.1 includes but is not limited to all proprietary oral or written information, data, reports, drawings and specifications, and all provisions of this Contract.

	6.4.2
	Both
Parties shall be responsible for the observance of the provisions of Clause 6.4.1 above by its employees.

	6.4.3
	The
provisions of Clause 6.4.1 above shall not apply to information which is or becomes generally known in the aero engine industry nor shall the provisions of
Clause 6.4.1 above prevent any necessary disclosure of information to enable ACA itself to operate, maintain or overhaul Supplies or to the extent disclosure is (i) required by
applicable law, or (ii) advised by a Party's legal counsel in response to the requirements of applicable law.

	6.4.4
	ACA
shall be responsible for obtaining any required authorization including any import licenses, exchange permits or any other governmental authorizations required in connection
with the transactions contemplated under this Contract. IAE shall be responsible for obtaining any export licenses required in connection with transactions contemplated under this Contract. ACA shall
restrict disclosure of all information and data furnished under this Contract in obtaining such licenses, permits, or authorizations. ACA shall only ship the Supplies and information and data
furnished under this Contract to those destinations permitted under such 

18

 

licenses,
permits, or authorizations, and shall obtain necessary approvals to ship supplies to ACA's maintenance facilities. 

	6.4.5
	In
the event that any of the Information as described in Clause 6.4.1 is required to be disclosed by either Party through a valid governmental, judicial or regulatory agency
order, or as a result of compliance with any law, the Party of whom such disclosure is required agrees to advise the other Party of the need for disclosure (in advance of such disclosure when
possible) and to limit the disclosure to only those portions of the Information specifically required to be disclosed by such order, and to maintain the confidentiality of as much of the Information
as legally possible.

	6.5
	Taxes

	6.5.1
	Subject
to Clause 6.5.2 below, IAE shall pay all imposts, duties, fees, taxes and other like charges [***] in connection with the Supplies prior to
their delivery.

	6.5.2
	All
amounts stated to be payable by ACA pursuant to this Contract exclude any value added tax, sales tax or taxes on turnover. [***] To ensure so far as
possible that ACA is not charged with European Community value added tax ("VAT"), ACA will within 30 days of signature hereof, inform IAE of its
VAT Code (if any) for inclusion on IAE's invoices.

	6.5.3
	Except
as otherwise set forth in this Section 6.5 and except for taxes imposed on or with respect to the gross or net income, receipts, conduct of business, minimum tax,
profits, gains, capital or net worth of IAE (including but not limited to [***].

	6.5.4
	IAE
will be responsible for any interest, penalties or fines imposed upon ACA because of IAE's failure to file any information return after requested in writing by ACA to do so or
should any representations made by IAE in this Contract or any documents required in this clause 6.5 prove to be false or misleading.

	6.5.5
	IAE
represents that all amounts payable by ACA under this Contract are, at the time of the execution of this Contract and will continue throughout the term of this Contract, to be
considered as income effectively connected with IAE's United States trade or business. Prior to receiving any payment under this Contract, IAE shall furnish ACA with a properly-completed IRS
Form W-8ECI, or other applicable form, evidencing its complete exemption from United States federal withholding taxes on any and all payments made. If for any reason ACA is required
by law to withhold taxes from any amounts payable under this Contract, IAE will receive such amounts payable net of such withholding.

	6.5.6
	If
this Agreement calls for the delivery of any of the Supplies in a jurisdiction that will result in the imposition of a sales tax or any other tax that ACA is required to pay
pursuant to this Agreement, upon ACA's written request the Parties will cooperate [***] to arrange for the sale to take place in a tax favorable jurisdiction, so as to avoid
the imposition of such tax, and if such arrangement cannot be reasonably achieved, then ACA may upon written notice to IAE [***].

	6.6
	Amendment

This
Contract shall not be amended in any way other than by written agreement by the Parties on or after the date of this Contract, which agreement is expressly stated to amend this Contract. 

	6.7
	Assignment

	6.7.1
	Except
as provided under Clause 5 above and further in this Clause 6.7, neither Party may assign any of its rights or obligations hereunder without the written consent
of the other Party (except that IAE may assign its rights to receive money hereunder). Any assignment made in violation of this Clause 6.7 shall be null and void. Notwithstanding the above, ACA
may, 

19

 

without
the consent of IAE assign this Agreement or any of its rights or obligations hereunder to any Qualifying Affiliate. A "Qualifying Affiliate"
shall mean an affiliate of ACA in which ACA either ([***]. In addition, ACA shall be permitted to consolidate with or merge into any other person, or sell, convey, lease, or
otherwise transfer all or substantially all of its assets as an entirety (whether in one transaction or a series of transactions) to any person (a "Reorganization
Transaction"), if the person formed by such consolidation or surviving such merger, or the person who acquires by sale, conveyance, transfer, or lease all or substantially all
of ACA's assets as an entirety (the "Successor") and the Successor, if other than ACA, executes and delivers to IAE an agreement, in form and substance
reasonably satisfactory to IAE, containing an assumption by the Successor of the due and punctual performance and observance of ACA's obligations under this Agreement. 

	6.7.2
	Before
tender of delivery of any Firm Spare Engine by IAE, ACA may assign (or create a security interest in) the right of ACA to purchase any Firm Spare Engine to a person or entity
that provides debt, equity or lease financing for the purchase of any Firm Spare Engine (or any trustee or agent for such a person or entity), pursuant to documentation in a form customarily accepted
by IAE. In the event of such an assignment ACA will continue to enjoy the service life policy and guarantees otherwise set forth herein except to the extent modified by the express terms of such
assignment.

IAE ESCALATION FORMULA  

	1.
	Any
unit base price or other sum expressed to be subject to escalation from a base month to a month of delivery or other date of determination in accordance with the IAE Escalation
Formula will be subject to escalation in accordance with the following formula: 

	 	 	Pi	 	=	 	(Pb + F) x CPI where:
	

 	
 	

Pi	
 	

=	
 	

the invoiced purchase price or escalated sum rounded to the nearest U.S. Dollar
	

 	
 	

Pb	
 	

=	
 	

unit base price or other sum
	

 	
 	

F	
 	

=	
 	

[***] (N) (Pb), rounded to the nearest U.S. Dollar
	

 	
 	

N	
 	

=	
 	

The calendar year of scheduled engine delivery or other date of determination, minus [***]
	

 	
 	

CPI	
 	

=	
 	

[***])
	

 	
 	

L	
 	

=	
 	

Labor Ratio defined below
	

 	
 	

M	
 	

=	
 	

Material Ratio defined below

The
IAE Composite Price Index (CPI) is the sum [***] Ratio and [***] Ratio, with the sum rounded to the nearest ten thousandth. 

The
quarterly value published for the Employment Cost Index will be deemed to apply to each month of the quarter. 

35

 

The
Labor Ratio is the "Employment Cost Index (ECI) Wages and Salaries for Aircraft Manufacturing, SIC Code 3721" as published by the Bureau of Labor Statistics, U.S. Department of Labor for the
arithmetic average of the fifth, sixth and seventh months (rounded to the nearest tenth) preceding the month of scheduled delivery; divided by the value of SIC Code 3721 for the arithmetic average of
the fifth, sixth and seventh months (rounded to the nearest tenth) preceding the base month. 

The
Material Ratio is the "Producer Price Indexes, Industrial Commodities", as published by the Bureau of Labor Statistics, U.S. Department of Labor, for the arithmetic average of the fifth, sixth and
seventh months (rounded to the nearest tenth) preceding the month of scheduled delivery; divided by the value for Industrial Commodities for the arithmetic average of the fifth, sixth and seventh
months (rounded to the nearest tenth) preceding the base month. 

	2.
	If
the U.S. Department of Labor changes the base year for determination of the Index values as defined above or revises the methodology used for the determination of the values to be
used to determine the CPI or, for any reason, has not released values needed to determine the CPI, IAE, in its sole discretion, shall select a substitute for such values from data published by the
Bureau of Labor Statistics or otherwise make revisions to the escalation formula such that the escalation will as closely as possible approximate the result that would have been attained by continuing
the use of the original escalation formula and values as they may have fluctuated during the applicable time period.

	3.
	The
invoiced purchase price or final escalated sum, which in no event shall be less than the unit base price, shall be the final price or final escalated sum.

        5.1.1    Account Representative:    

An
Account Representative is assigned to each customer using IAE equipment. This representative provides individualized attention for effective spare parts order administration, and is the customer's
interface on all matters pertaining to new part planning and procurement. Each representative is responsible for monitoring each assigned customer's requirements and providing effective administrative
support. The Account Representatives are thoroughly familiar with each customer's spare parts ordering policies and procedures and are responsible for ensuring that all customer new parts orders are
processed in an effective manner. 

        5.1.2    Spare Parts Provisioning Planning:    

Prior
to delivery of the first Atlantic Coast Airlines aircraft to an airline customer, preplanning discussions will be held to determine the aircraft/engine program, and engine spare parts
provisioning and order plans. Mutually agreed upon provisioning target dates are then established and on-time completion tracked by the Customer Account Representative with the assistance
of logistics specialists in Spare Parts Provisioning and Inventory Management. Meetings are held with airline customers at a mutually agreeable time to review suggested spare parts provisioning lists
prepared by spare parts Provisioning. These lists are designed to support each customer's particular fleet size, route structure and maintenance and overhaul program. 

        5.1.3    Order Administration:    

IAE
subscribes to the general principles of Air Transport Association of America (ATA) Specification No. 2000, Integrated Data Processing—Supply. The procedures of Air Transport
Association of America (ATA) Specification No. 200 may be used for Initial Provisioning (Chapter II), Order Administration (either Chapter III or Chapter VI), or Invoicing (Chapter IV). 

The
lead time for replenishment spare parts is identified in the IAE spare Parts Price Catalog. Initial provisioning spare parts orders should be placed at least [***] prior to
required delivery, while conversions and major modifications require full manufacturing lead times. 

The
action to be taken on emergency requests will be answered as follows: 

	•
	Aircraft-On-Ground
(AOG)—within four hours (in these instances every effort is made to ship immediately).

	•
	Critical
(Imminent Aircraft-On-Ground (AOG) or Work Stoppage)—Within [***].

	•
	Stock
Outage—Within [***] (these items are shipped as per customer request). 

        5.1.4    Spare Parts Inventory:    

To
ensure availability of spare parts in accordance with published lead time, spare parts provisioning maintains a modern, comprehensive requirements planning and inventory 

54

 

management
system which is responsive to changes in customer demand, special support programs and engineering design. Organized on an engine model basis, this system is intended to maintain part
availability for delivery to customers consistent with published lead times. 

A
majority of parts in the spare parts inventory are continually controlled by an Automatic Forecasting and Ordering System. Those parts which do not lend themselves to automatic control due to
supercedure, unusual usage or conversion requirements are under the direct manual control of Spares Planning personnel. As additional protection against changes in production lead time or unpredicted
demand, certain raw materials are also inventoried. Successful inventory management is keyed to accurate requirements planning. In support of the requirements planning effort, a wide ranging data
retrieval and analysis program is offered. This program concerns itself both with the customer logistics and technical considerations as follows: 

	•
	Forecasts
of life limited parts requirements are requested and received semi-annually from major customers.

	•
	Engine
technical conferences are held frequently within IAE to assess the impact of technical problems on parts.

	•
	For
a selected group of parts a provisioning conference system is offered which considers actual part inventory change, including usage and receipts, as reported monthly by
participating customers. 

        5.1.5    Packaging    

All
material is packaged in general compliance with Air Transport Association of America (ATA) Specification No. 300. 

        5.1.6    World Airline Supplier's Guide:    

IAE
subscribes to the supply objectives set forth in the World Airlines Supplier's Guide published by the Air Transport Association of America (ATA). 

IAE
requires that its proprietary component vendors also perform in compliance with the precepts of the World Airline Suppliers' Guide.

First Run Nacelle is a Nacelle with no more than 6,000 hours Nacelle Time and a First Run Nacelle Part is a Part with no more than 6,000 hours Parts Time operating in a
First Run Nacelle.

	2.
	If
a First Run Nacelle Part suffers Direct Damage or Resultant Damage, and provided that the Part causing Resultant Damage is also a First Run Nacelle Part:

	a.
	IAE
will grant to the Operator:

	(1)
	A
[***] percent Parts Credit Allowance for any such First Run Nacelle Part Scrapped, and

	(2)
	A
[***] percent Labor Allowance for Parts Repair of any First Run Nacelle Part requiring Parts Repair.

	b.
	If
such Damage of a First Run Nacelle Part causes the removal of the Nacelle from the Aircraft, IAE will, in addition to Subparagraph a. above, grant to the Operator:

	(1)
	A
[***] percent Labor Allowance for disassembly, reassembly and necessary testing of the Nacelle requiring Reconditioning as a result of such Damage of the
First Run Nacelle Part, and

	(2)
	A
[***] percent Parts Credit Allowance for those Expendable Parts required in the Reconditioning of the Nacelle.

	c.
	If
such Damage of a First Run Nacelle Part causes the removal of the Nacelle from the Aircraft, IAE will arrange, upon request by the Operator, to Recondition the Nacelle or accomplish
the Parts Repair at no charge to the Operator rather than providing the above Allowances. Such work will be accomplished at a V2500 Maintenance Center designated by IAE. Transportation charges to and
from the Maintenance Center shall be paid by the operator.

	B.
	Primary Part

	1.
	A
Primary Part is a Part other than a First Run Nacelle Part but having not more than [***] Parts Time.

	2.
	Primary
Parts not eligible for those Allowances granted to First Run Nacelle Parts are eligible for Allowances under this Section I, Paragraph B, provided that the
Primary Part suffers Direct Damage or Resultant Damage and provided that the Part causing Resultant Damage is also a Primary Part.

	3.
	IAE
will grant to the Operator a Parts Credit Allowance for such a Primary Part Scrapped or a Labor Allowance for such a Primary Part for which a Parts Repair is designated in writing
by IAE as being eligible for adjustment under this Section I, Paragraph B. Such Allowance will be based on [***] percent to [***] Parts
Time which then decreases, pro rata, to [***] percent at [***].

	II
	CAMPAIGN
CHANGE ALLOWANCES AND ADJUSTMENTS

	A.
	A
Campaign Change is an IAE program, so designated in writing, for the Reoperation, replacement, addition, or deletion of a Part(s). IAE will grant the Allowances and adjustments
specified in this Section II to the Operator when Campaign Change recommendations are complied with by the Operator. 

76

 

	B.
	Standard Allowances

Change and such disassembly is performed solely for the purpose of accomplishing the Campaign Change.

	C.
	Optional Allowances and Adjustments

	1.
	Should
IAE declare a Campaign Change, the Operator may propose an alternative means of complying with a Campaign Change by submitting such alternate means to IAE for certain credits
and adjustments (the "Credit Allowance and Adjustments"). IAE shall then reasonably determine the eligibility of such alternative means. If IAE reasonably determines that such alternate means is not
acceptable, IAE will grant to the Operator the credit allowances and adjustments described in clauses II (A), (B) and (C) above. If IAE reasonably determines that such alternate means is
acceptable, IAE will grant to the Operator Credit Allowances and Adjustments, such as, but not necessarily limited to:

	a.
	No
charge material

	b.
	Specially
priced material

	c.
	Single
payment settlements for the Operators' fleet

	d.

fuel consumption for Eligible Engines at the time of commencement of commercial operation will not have increased by more than a Guaranteed Margin of [***] Under this
Guarantee, if the cumulative fleet average cruise fuel consumption for Eligible Engines exceeds the Guaranteed Margin at the end of the Guarantee Period, IAE's sole obligation will be to credit ACA's
account with IAE an amount in respect of excess fuel consumed. 

	II
	GUARANTEE

        A.    Period of Guarantee    

The
Period of Guarantee shall start on the date ACA initiates commercial operation of its first Aircraft powered by Eligible Engines and will terminate for each Eligible Engine originally installed on
the Aircraft in accordance with the schedule set forth in Clause D of Exhibit D-4 ("Period of Guarantee"). 

        B.    Anniversary Date    

The
Anniversary Date for administration of this guarantee is each anniversary of the start of the guarantee period. 

        C.    Period of Calculation    

The
Period of Calculation for administration of this guarantee is the year preceding each Anniversary Date. 

        D.    Eligible Engines    

The
Engines that will be Eligible under this Guarantee shall be the Engines which have been acquired pursuant to the Contract to which this Guarantee is attached or contract for delivery of the
Aircraft, and shall (as a matter of clarification) also include for purposes of this Guarantee, the Leased Aircraft. The eligibility of the installed Engines and Firm Spare Engines under this
Guarantee is contingent upon such Engines and Firm Spare Engines being maintained in accordance with the reasonable written operating and maintenance instructions (which take into account ACA's
operational needs) issued by IAE and the Aircraft Manufacturer, which instructions are consistent with and do not contradict the maintenance program for the Aircraft and the Engines developed and
agreed to by ACA in accordance with Federal Aviation Administration requirements. 

        E.    Fuel Consumption Measurement    

The
inflight data required for administration of this Guarantee will be obtained by ACA during steady state cruise conditions using methods which shall be mutually agreed between ACA and IAE prior to
entry into service of the first Aircraft and may include, at ACA's option, ECM data recordings and the ECM II software available from IAE (requires the ECM sales order option from Airbus). 

Provided
that: 

	a)
	the
fuel consumption data for any Eligible Engine on which the engine parameters indicate a possible malfunction (including associated Aircraft systems), other than normal 

96

 

gas
path deterioration, that is subsequently confirmed by maintenance action will not be considered acceptable data, and 

	b)
	data
which is obviously inaccurate under normal engine monitoring practices will not be considered acceptable data; this type of data will be rejected unless ACA validity checks have
established that Total Air Temperature, Fuel Flow Aircraft and Engine Bleed Systems and other Aircraft parameters are within normal operating ranges. 

The
data to be recorded will be that normally recorded for Engine Condition Monitoring purposes and will include the following: 

Altitude

Mach Number

Total Air Temperature (TAT)

Indicated Airspeed (IAS)

Engine Pressure Ratio (EPR)

Fuel Flow

Low Compressor Rotor Speed (N1)

High Compressor Rotor Speed (N2)

Bleed Air Configuration

Engine
Fuel Flow measurements will be referred to in the Standard Engine Fuel Flow-Engine Pressure Ratio Relationship which will be defined for installed Engines by the Aircraft
manufacturer during the Aircraft flight test certification program. 

        F.    Base Fuel Flow    

The
Base Fuel Flow shall be the initial fuel flow level of each Eligible Engine on commencement of its commercial service. This shall be the average of the cruise fuel flow values for the first ten
Acceptable Data Points, which are data points which are not manifestly aberrant, recorded for each Eligible Engine. Base Fuel Flow is represented as a percentage deviation from the Standard Engine
Fuel Flow-Engine Pressure Ratio Relationship. 

        G.    Cruise Fuel Flow    

The
Cruise Fuel Flow shall be the average of the cruise fuel flow values for ten Acceptable Data Points, which are data points which are not manifestly aberrant, for each installed Eligible Engine at
any time after that Engine's Base Fuel Flow is established. Cruise Fuel Flow will also be expressed as a percent deviation from the Standard Engine Fuel Flow-Engine Pressure Ratio
Relationship. 

        H.    Engine Cruise Fuel Flow Deterioration    

The
Cruise Fuel Flow Deterioration for an Eligible Engine shall be the difference between its Cruise Fuel Flow and the Base Fuel Flow expressed in percentage points. 

        I.    Fleet Average Cruise Fuel Consumption Deterioration    

The
Fleet Average Cruise Fuel Consumption Deterioration shall be the cumulative average of the Cruise Fuel Flow Deterioration for all installed Eligible Engines at the Anniversary Date. This is to be
reported to IAE at each Anniversary Date. 

97

 

        J.    Operational Data    

ACA
shall provide the following data to IAE as indicated during the Period of the Guarantee at each Anniversary Date: 

	1.
	Total
quantity of fuel consumed by Eligible Engines during the Period of Calculation (U.S. Gallons).

	2.
	Average
cost of fuel to ACA for the Period of Calculation (U.S. Dollars per U.S. Gallon.

	3.
	Individual
Eligible Engine operating hours for the Period of Calculation identified by engine serial number.

	4.
	Engine
maintenance action information, as requested. 

ACA's
failure to provide data will not invalidate the coverage provided by this Guarantee if data can be accurately recreated unless the data was specifically requested by IAE and ACA failed to
provide the information in a timely manner. 

        K.    Excess Fuel Consumption Credit Calculation    

If
at the end of each Period of Calculation the Fleet Average Fuel Consumption Deterioration exceeds the Guaranteed Margin, IAE will grant ACA a credit in respect to excess fuel consumption calculated
in accordance with the following formula: 

C =  (D-GM)%
YHF 

where: 

C =
the amount of the credit in U.S. dollars 

D
= the Fleet Average Fuel Consumption Deterioration 

GM
= the Guaranteed Margin 

Y =  average
cruise fuel flow of new Eligible Engines expressed in U.S. gallons per hour at the time of commencement of commercial operation for each such Eligible Engine 

H =  the
total of all flight hours flown by ACA's Eligible Engines during the Period of Calculation 

F =  The
average net cost to ACA in U.S. Dollars per U.S. Gallon (after deduction of subsidies or government or other allowances received by ACA), of aviation fuel consumed by ACA
during the Period of Calculation. 

If
subsequent annual calculations show that on a cumulative basis, a previous credit (or portion thereof) was in excess of that due under this Guarantee, such excess amount shall be subject to
repayment which will be effected by IAE issuing a debit against ACA's account with IAE. At ACA's option, the Credit Calculation may be made using the ECM Trend Monitoring Program. In such an event,
the above-referenced reporting requirements will be satisfied through provision by ACA of the necessary reporting data as part of the ECM Trend Monitoring Program and will be provided to IAE on a
regular basis.

provisions of Clause 2 of this Contract and Side Letter No. 1 notwithstanding, in the event of a Aircraft Total Loss of an Aircraft under paragraph (1) above
(provided that ACA elects to take delivery of a replacement Aircraft), all applicable credits stated in the Contract to be subject to escalation will be escalated [***]
calculated in accordance with the IAE Escalation Formula set forth in Exhibit B-2 to this Contract, from (a) the original scheduled Aircraft delivery month for such Aircraft
in effect prior to the occurrence of such Aircraft Total Loss to (b) the actual delivery month of the aircraft replacing such Aircraft.

	C.
	Inexcusable
Delay 

IAE
acknowledges and agrees to the following: 

	(1)
	under
the Aircraft Purchase Agreement, ACA and AVSA contemplate events whereby an Aircraft is not ready for delivery within [***] days after the last day of
the scheduled Aircraft delivery month and such delay is not a result of an Airbus Excusable Delay, Total Loss [***]. Such an event will be termed an
"Airbus Inexcusable Delay";

	(2)
	if
an Airbus Inexcusable Delay occurs, AVSA will promptly, after the removal of the cause of the Airbus Inexcusable Delay, resume performance of its obligations under the Aircraft
Purchase Agreement and notify ACA of the revised scheduled Aircraft delivery month;

	(3)
	if,
as a result of an Airbus Inexcusable Delay, (i) delivery of the Aircraft does not occur within [***] after the last day of the scheduled Aircraft
delivery month or (ii) in AVSA's reasonable judgment such Airbus Inexcusable Delay is expected to result in delivery of the affected Aircraft after such [***], ACA will
then have the right exercisable by written notice to AVSA to require from AVSA a renegotiation of the scheduled Aircraft delivery month for the affected Aircraft, provided that such notice is given,
(a) in the case of (i) above, within thirty (30) days following the expiration of the [***] or, (b) in the case of (ii) above, within thirty
(30) days following AVSA's notice that such Airbus Inexcusable Delay is expected to extend beyond such [***];

	(4)
	if,
as a result of an Airbus Inexcusable Delay, delivery does not occur within [***] after the last day of the scheduled Aircraft delivery month and ACA and
AVSA have not 

6

 

renegotiated
the scheduled Aircraft delivery month pursuant to paragraph (3) above, or, [***] after the last day of the scheduled Aircraft delivery month, then ACA will
have the right exercisable by written notice to AVSA, given within [***] following expiration of such [***] or within [***] of
AVSA's notice informing ACA that such Airbus Inexcusable Delay is expected to extend for a period of more than [***] after the last day of the scheduled Aircraft delivery
month, as the case may be, to terminate the Aircraft Purchase Agreement in respect of the affected Aircraft; 

	(5)
	if,
as a result of an Airbus Inexcusable Delay, delivery does not occur within [***] after the last day of the scheduled Aircraft delivery month and ACA and
AVSA have not renegotiated the scheduled Aircraft delivery month pursuant to paragraph (3) above, or, [***] after the last day of the scheduled Aircraft delivery month,
then both ACA and AVSA will each have the right exercisable by written notice to the other party, given [***] of after the last day of the scheduled Aircraft delivery month, as
the case may be, to terminate the Aircraft Purchase Agreement in respect of the affected Aircraft. However, notwithstanding the foregoing, [***];

	(6)
	any
or all of the events described under paragraphs (1) through (5) above may affect ACA's ability to accept delivery of an Aircraft pursuant to the delivery schedule
set forth under Exhibit B-1 to this Contract, and if any of such events occur, ACA is authorized to amend the Aircraft delivery schedule under Exhibit B-1 to
reflect the revised delivery month for such Aircraft, or the cancellation of the delivery of such Aircraft, as applicable, as agreed between ACA and AVSA; and

	(7)
	the
provisions of Clause 2 of this Contract and Side Letter No. 1 notwithstanding, in the event of an Airbus Inexcusable Delay, [***], in
accordance with the IAE Escalation Formula set forth in Exhibit B-2 to this Contract, without regard to the actual delivery month; provided that [***].

	D.
	BFE
Delay

	(1)
	Under
the Aircraft Purchase Agreement, ACA requires AVSA to provide for the installation of Buyer Furnished Equipment (BFE) on the Aircraft. IAE acknowledges that any delay or failure
by ACA to furnish the BFE in a serviceable condition at the delivery date requested by AVSA pursuant to the Aircraft Purchase Agreement may cause delay in the performance of any act to be performed by
AVSA and thus delay delivery of the Aircraft. IAE further acknowledges and agrees that such a delay may affect ACA's ability to accept delivery of an Aircraft pursuant to the delivery schedule set
forth under Exhibit B-1 to this Contract, and ACA is authorized to amend the Aircraft delivery schedule under Exhibit B-1 to reflect the revised delivery month
for such Aircraft, as agreed between ACA and AVSA.

	(2)
	The
provisions of Clause 2 of this Contract and Side Letter No. 1 notwithstanding, in the event of such a delay or failure described above,
[***], in accordance with the IAE Escalation Formula set forth in Exhibit B-2 to this Contract; provided that [***].

	E.
	Short-Term
Delays

	(1)
	The
provisions of Clause 2 of this Contract and Side Letter No. 1 notwithstanding, IAE acknowledges and agrees that all applicable credits will be adjusted to the
scheduled delivery month of the Aircraft without regard to the actual delivery month, if, after ACA's receipt of at least [***] days' written notice from AVSA of the
anticipated date on which the Aircraft is ready for delivery, as required under the Aircraft Purchase Agreement, an Aircraft is not ready for delivery within the scheduled Aircraft delivery month due
to a delay in, or the extension of, time required to successfully complete the applicable 

7

 

technical
acceptance process developed by AVSA when such delay or extension is (i) either (x) due to the technical noncompliance of the Aircraft that is not due to an Airbus Excusable
Delay or (y) due to any other delay that, but for the passage of time, would be an Airbus Inexcusable Delay, (ii) [***] and (iii) is not otherwise
addressed between ACA and AVSA to ensure timely Aircraft delivery. 

	(2)
	IAE
further acknowledges and agrees that such a failure for the Aircraft to successfully complete the technical acceptance process may affect ACA's ability to accept delivery of an
Aircraft pursuant to the delivery schedule set forth under Exhibit B-1 to this Contract, and ACA is authorized to amend the Aircraft delivery schedule under
Exhibit B-1 to reflect the revised delivery month for such Aircraft, as agreed between ACA and AVSA.

reasonable period thereafter as needed by the Lessor to ascertain Lessee's compliance with the terms and conditions of the Contract; provided, that Lessor shall return to Lessee within
[***] any undisputed portion of the security deposit. The security deposit may be applied by the Lessor, at its sole discretion, to remedy any non-performance by
Lessee of its obligations thereunder, without prejudice to any other remedies that the Lessor may have. Lessee will provide to Lessor, within [***] days, any such amount of the

Period of Lease will be divided into thirty (30) day Rental Periods beginning on the Delivery Date. Lessee will pay to Lessor an amount equal to the daily lease rate
multiplied by thirty (30) days, in advance, on the first day of each Rental Period. Such amount shall be applied against the outstanding daily lease charges actually accrued during the
following Rental Period, or part thereof. In the event that the following Rental Period is less than thirty (30) days, Lessor will refund to Lessee any amounts remaining at the rate of the
daily lease rate times the number of days remaining unused; provided however, that Lessor shall have the right to deduct from such refundable amounts any amounts owing by Lessee to Lessor under this
Agreement.

	10.4

charges under sub-clause 10.2.1 above shall be indicated to the Lessee annually and shall hold good for periods of lease during the calendar year of indication

otherwise agreed in writing prior to the commencement of the Period of Lease, Lessee's obligation to pay the daily lease charges and the hourly usage charges will be absolute

	10.5.7
	any
invalidity or unenforceability or lack of due authorization of or other defect in this Agreement or any other of the documents involved in the transaction of which this
Agreement forms part;

	10.5.8
	any
other cause outside of Lessor's reasonable control which, but for this provision, would, or might, have the effect of terminating, frustrating or in any way affecting any
obligation of the Lessee hereunder; it being the declared intention of the parties that the provisions of this Clause and the obligations of the Lessee to pay the daily lease charges, hourly usage
charges and a termination sum in accordance with Clause 16 below, and any other amounts provided hereunder will survive any frustration and that, save as expressly provided in this Agreement,
no moneys payable hereunder by the Lessee to Lessor will in any event or circumstances be repayable to the Lessee.

	10.5.9
	If
the Supplies become a Total Loss, then the daily lease charges will cease to accrue from the date on which Lessor receives the required amount in accordance with
Clause 15.

	2.
	Under the Legal Liability Insurance

	2.1
	Subject
to the provisions of this Endorsement, the Insurance shall operate in all respects as if a separate Policy had been issued covering each party insured hereunder, but this
provision shall not operate to include any claim howsoever arising in respect of loss or damage to the Equipment insured under the Hull or Spares Insurance of the Insured. Notwithstanding the

	3.3
	The
provisions of this Endorsement apply to the Contract Party(ies) solely in their capacity as lessor(s) in the identified  Contract(s) and not in any other
capacity. Knowledge that any Contract Party may have or acquire or
actions that it may take or fail to take in that other capacity (pursuant to any other contract or otherwise) shall not be considered as invalidating the cover afforded by this Endorsement.

	3.4
	The
Contract Party(ies) shall have no responsibility for premium and Insurers shall waive any right of set-off or
counterclaim against the Contract Party(ies) except in respect of outstanding premium in respect of the  Equipment.

	3.5
	Upon
payment of any loss or claim to or on behalf of any Contract Party(ies), Insurers shall, to the extent and in respect of such
payment, be thereupon subrogated to all legal and equitable rights of the Contract Party(ies) indemnified hereby (but not against any  Contract Party).
Insurers shall not exercise such rights without the consent of those indemnified, such consent not to be unreasonably withheld. At the
expense of Insurers, such Contract Party(ies) shall do all things reasonably necessary to assist the Insurers to exercise said rights.

is given by the Insurers. Such notice will NOT, however, be given at normal expiry date of the Policy or any endorsement.
