IAE’s liability and AAH’s remedies under this warranty are limited to the repair or replacement, at IAE’s election, of Supplies or portions thereof returned to IAE at the place so instructed by IAE which are shown to IAE’s reasonable satisfaction to have been defective; provided, that written notice of the defect shall have been given by AAH to IAE within ninety (90) days after the first operation or use of such Supplies or within thirty (30) days after the defect has become apparent (or if the Supplies are installed in new Aircraft, within ninety (90) days after acceptance of such Aircraft by its first operator) but in no event later than one (1) year after the date of delivery of such Supplies by IAE. Transportation charges for the return of Supplies to IAE pursuant to this Clause 4.1 and their reshipment to AAH and the risk of loss thereof will be borne by IAE provided the Supplies are returned in accordance with written shipping instructions from IAE and are defective and provided that IAE shall have provided such written shipping instructions promptly.

Page 19 of 118

4.4	The Warranties are personal to AAH and to AAH for the benefit of the Grupo Taca Airlines and the obligations of IAE thereunder shall only apply insofar as AAH and/or a Grupo Taca Airline owns and operates the Supplies covered thereunder. IAE agrees, as a minimum, to grant any lessee or purchaser of the Supplies (whether installed on Aircraft or not) a direct warranty agreement as set forth in Exhibit E to this Contract.
4.5	AAH 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 and IAE hereby agrees to enter into a direct warranty agreement with any such entity (at no additional charge to AAH or such entity) incorporating those of the Warranties set out in Clauses 4.2.1 and 4.2.2. AAH 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	IAE and AAH agree that the intent of the Warranties provided in Clause 4.2 is to provide specified benefits or remedies as a result of specified events. It is not the intent, however, to duplicate benefits or remedies provided to AAH by IAE or another source (e.g., another equipment manufacturer or lessor) as a result of the same event or cause. Therefore, notwithstanding the terms of the Warranties, AAH agrees that it shall not be eligible to receive benefits or remedies from IAE to the extent it results in AAH or Grupo Taca Airlines receiving duplicative benefits or remedies from IAE or another source as a result of the same event or cause. Furthermore, in no event shall IAE be required to provide duplicate benefits to AAH and any other party such as a leasing company as a result of the same event or cause.

The labor rate calculated pursuant to the standard IAE labor rate letter may be revised from time to time as described in the letter.

6.1.2	If, by reason of any of the causes embraced by Clause 6.1.1 above, IAE is hindered or prevented from or delivering any goods (which are the same as and include the Supplies) to purchasers (including AAH) then IAE shall have the right to allocate such goods, as they become available, at its own discretion among all such purchasers and IAE shall not be under any liability whatsoever to AAH for delay in delivery to AAH resulting from such allocation by IAE and the time for delivery shall be extended by a period equal to the delay resulting from such allocation by IAE.
6.1.3	Should IAE inexcusably delay performance of any obligation hereunder including but not limited to delivery of any item of the Supplies beyond the time for delivery specified in this Contract (as such time may be extended pursuant to the provisions of this Contract), then in respect of the first [*] of such delay, IAE shall not be under any liability whatsoever and thereafter in respect of any further delay in delivery the damages recoverable by AAH from IAE as AAH’s sole remedy shall be its reasonable actual damages in an amount not to exceed [*] of the purchase price of the item of Supplies so delayed in respect of each month of such further delay (and prorata for any period of less than one month) subject to an overall maximum of [*] of the purchase price of the item of the Supplies so delayed.

6.2	Patents
	6.2.1	IAE shall, subject to the conditions set out in this Clause and as the sole liability of IAE in respect of any claims for infringement of intellectual property rights, indemnify AAH against any claim that the use of any of the Supplies by AAH within any country to which at the date of such claim the benefits of Article 27 of the Convention on International Civil Aviation of 7th December l944 (The Chicago Convention) and the International Convention for the Protection of Industrial Property apply, infringes any patent, design, or model duly granted or registered provided, however, that IAE shall not be liable to AAH for any consequential damage or any loss of use of the 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	AAH 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.

6.3	Credit Reimbursement
	If AAH does not take delivery of the [*] Firm Aircraft, the [*] Firm Spare Engines, and to the extent that Rolling Option Aircraft are acquired, those Rolling Option Aircraft and the required number of Option Spare Engines (each Firm Aircraft, Firm Spare Engine, Rolling Option Aircraft and Option Spare Engine equally a “Firm Item”) in accordance with the schedules described in Exhibits B-1 and B-2 to the Contract (as such may be modified or supplemented pursuant to the terms of the Contract) then, without prejudice to IAE’s other rights and remedies under the Contract or otherwise, the value of each and every credit, benefit and other concession received by AAH pursuant to the Contract (including all Side Letters and amendments thereto) or from IAE via the Aircraft Manufacturer will be adjusted to pro-rata amounts, based on the ratio of the number of Firm Items (whether Aircraft or Spare Engines) purchased in accordance with the schedules described in Exhibits B-1 and B-2 to the Contract to the total number of Firm Items scheduled to have been so purchased. So, for example, if IAE is to issue credits on delivery of each Firm Item and AAH takes delivery of only half the total number of such Firm Items (whether or not with the consent of the Aircraft Manufacturer) the value of each credit to be issued on the Firm Items actually taken and all other credits (if any) will be reduced by half. Following such adjustment, AAH will promptly reimburse IAE in an amount equal to (a) the value of the credits, benefits and other concessions actually provided in excess of the adjusted amounts, plus (b) the interest on such excess amounts calculated from the time each respective amount was applied or value received until reimbursement. Interest will be calculated at [*] in effect at the time each respective amount was applied or value was received. If AAH is in default of any payment obligations under the terms of this Contract, IAE will, without prejudice to any of its other rights be entitled to offset any unused IAE credit in AAH’s account with IAE against such outstanding amount.

The expression “Information” in this Clause 6.4.1 includes but is not limited to all oral or written information, know-how, data, reports, drawings and specifications, and all provisions of this Contract.
	6.4.2	Each party shall be responsible for the observance of the provisions of Clause 6.4.1 above by its employees and professional advisors.
	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 the other to operate, maintain or overhaul Supplies, nor to information required to be disclosed by a valid governmental, judicial or regulatory agency order or subpoena.
	6.4.4	AAH shall be responsible for obtaining any required authorization including any export licenses (other than export licenses for the country of manufacture), import licenses, exchange permits or any other governmental authorizations required in connection

		with the transactions contemplated under this Contract. AAH shall restrict disclosure of all information and data furnished under this Contract in obtaining such licenses, permits, or authorizations. AAH shall only ship the Supplies and information and data furnished under this Contract to those destinations permitted under such licenses, permits, or authorizations.
	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, that party agrees to advise the other of the need for disclosure (in advance of such disclosure when possible) and to limit the disclosure to those portions of the Information required to be disclosed by such order, and to maintain the confidentiality of as much of the Information as legally possible in the sole good faith judgment of the party so ordered.

	6.5.2	All amounts stated to be payable by AAH pursuant to this Contract exclude any value added tax, sales tax or other similar tax. In the event that the supply of goods or services under this Contract is subject to any value added tax, sales tax or other similar tax, such tax will be borne by AAH. To ensure so far as possible that AAH is not charged with value added tax (“VAT”) of the European Union or any member country thereof, AAH will within thirty (30) days of signature hereof, inform IAE of its VAT Code (if any) for inclusion on IAE’s invoices. Further, each party agrees to reasonably cooperate with the other to reduce the tax liabilities of the other.
	6.5.3	AAH shall pay all other imposts, duties, fees, taxes and other like charges by whomsoever levied other than (i) taxes on IAE’s gross or net income or gains; (ii) taxes which would not have been imposed but for a connection between IAE and the taxing jurisdiction unrelated to this Agreement; and (iii) taxes which would not have been imposed but for the gross negligence of willful misconduct of or a breach of this Agreement by IAE.

6.7	Assignment
	Except as provided under Clause 5.1 above, 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 or its rights and obligations, or a portion thereof, to any wholly owned subsidiary of IAE or to any of IAE’s shareholders subject to such subsidiary or shareholders being able to fulfill the obligations being assigned). Any assignment made in violation of this Clause 6.7 shall be null and void.
	IAE understands that AAH may use any of various mechanisms to finance or acquire the Aircraft or to refinance its acquisition of an Aircraft, including a sale leaseback whereby AAH or the Aircraft Manufacturer sells the aircraft to a third party and a Grupo TACA Airline leases the Aircraft from the third party. IAE agrees to reasonably consider AAH’s timely requests that IAE consent to the assignment of AAH’s rights or obligations hereunder to facilitate the financing, acquisition or refinancing of the Aircraft. In respect of the purchase of the Aircraft or a sale leaseback of the Aircraft, IAE agrees that AAH may assign the Contract with respect to the particular affected Aircraft to an affiliated Special Purpose Corporation or the purchaser/lessor in a sale leaseback transaction.
	IAE also understands that AAH is an operating lessor and not an operator of equipment and that Grupo Taca Airlines will be the ultimate users of the Aircraft and Supplies. Furthermore, Grupo Taca Airlines may be the purchasers of the Supplies (with the exception of the Spare Engines). AAH may make an assignment of the relevant portions of the Contract (including but not limited to the relevant portions of Clauses 1, 3, 4 and 6) relating to the purchase of Supplies with recourse to AAH except that IAE shall retain the right to amend Clause 3.13.

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.

SPARE PARTS PROVISIONING PLANNING

Prior to delivery of the first new 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.

ORDER ADMINISTRATION

IAE subscribes to the general principles of Air Transport Association of America (ATA) Specification No. 200, 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) Invoicing (Chapter IV).

A spare parts supply objective is to maintain a 90 percent on-time shipment performance record to our published lead times. 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 six months 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 24 hours.

• Stock Outage — Within seven working days (these items are shipped as per customer request).

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 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.

THIS DOCUMENT CONTAINS INFORMATION PROPRIETARY TO IAE.

Page 78 of 118

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.

PACKAGING

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

WORLD AIRLINE SUPPLIERS’ 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.
