  (g) the continued operation in regular and frequent commercial service of the fleet of the Eligible Engines;

 

  (h) each Aircraft type being operated as a whole with the same average operating parameters for each Aircraft in the Aircraft type fleet. If a fleet operates as two or more groups of Aircraft with different mission parameters then rates shall be recalculated as if a fleet consisted of two or more sub-fleets, as the case may be. A fleet shall be considered to operate as a whole provided the average operation of any single Aircraft over the Period of FHA is not materially different to such average of a fleet as a whole;

 

  (i) Engines are to operate in an operating environment similar to Spirit’s existing operation, that does not contain abnormal levels of abrasive or erosive pollutants significantly different than those in Spirit’s current operating environment; and

 

  (j) Maintaining Spare Engine and Spare Parts Coverage as per Clauses 5 and 10.2.

10.5.2.    IAE, acting reasonably, in consultation with Spirit, may make adjustments to the FHA Rates in Clause 10.5.1 if (i) there is a change in any of the preceding conditions; (ii) additional aircraft powered by V2500-A5 engines or V2500-A5 spare engines are acquired by Spirit; or (iii) there is a discontinuation of operation by Spirit of any Eligible Engine or Aircraft causing it not to operate for ***** continuous years under the FHA. Any such adjustment shall take into account the Eligible Engine Flight Hours accrued by the Eligible Engines and Spare Engines up to the effective date of the amendment to the FHA Rate. Such changes will be made using methodology that is consistent with the methodology used to develop the original rates.

 

  10.5.3. Engines In; Engines Out

 

  10.5.3.1 Beyond Economic Repair (“BER”). If an eligible engine leaves the FHA for reasons beyond the control of Spirit, for example, an eligible engine is deemed beyond economic repair, and is replaced by Spirit with a materially dissimilar engine (as determined by IAE in consultation with Spirit), the FHA rates for that engine, and not all eligible engines, will be adjusted.

Page 30

 

Either Party shall have the option, at its sole discretion, to terminate this Agreement upon the occurrence of any of the following events: (a) a receiver or trustee is appointed for any of the other Party’s property, or (b) the other Party is adjudicated or voluntarily becomes bankrupt under any bankruptcy or winding up laws or other similar legislation, or (c) the other Party becomes insolvent or makes an assignment for the benefit of creditors.

 

  21.2. Failure to Make Payments or to Meet Obligations

A non-defaulting Party shall have the right to declare an event of default and terminate this Agreement (i) if any default shall occur in the payment by the defaulting Party of any material amount hereunder when and as the same becomes due and payable and such default continues, after notice from the non-defaulting Party for a period of ***** calendar days or more and is not the subject of a good faith dispute between the Parties; or (ii) for a failure by the defaulting Party to meet any other material obligation under this Agreement, and such failure shall not have been fully corrected within ***** calendar days after the giving of notice thereof to the defaulting Party and is not the subject of a good faith dispute between the Parties.

If Spirit fails to make payment of any material amount due and owing to IAE as set forth in Clause 10 of this Agreement (including any interest due thereon) and such amount is not the subject of a good faith dispute between the Parties, then after notice to Spirit and the expiration of a ***** calendar days cure period and without prejudice to any of IAE’s other rights which IAE may have in contract or in law, IAE reserves the right not to induct, to suspend all work on, or not to release from the Maintenance Center(s) any Eligible Engine until full payment is made by Spirit to IAE.

The obligation of IAE to provide, or cause to be provided, the services set out in this Agreement shall be subject to the non-existence of a continuing material event of default by Spirit of any payment or other obligation of Spirit under the Support Contract, this Agreement or any other agreement in effect between the Parties (an “Event of Default”). Should any such Event of Default exist, IAE reserves the right not to induct, to stop all work on, or not to release from the Maintenance Center any Eligible Engine until such default is rectified by Spirit to IAE’s satisfaction.

 

  21.3. Expiration

This Agreement shall be effective from the day and year first before written until the end of the Period of FHA, at which point each element of the coverage set out under this Agreement shall cease to be provided to Spirit by IAE, except that the Spare Engine Coverage shall be effective for the Period of Spare Engine Coverage as defined in Clause 5.1 and the IAE obligations described in Clause 21.4.4 shall survive the expiration or termination of the Period of FHA.

Except as otherwise set out in this Clause 21.4 and any rights or obligations arising under the applicable law, the rights and obligations of the Parties under this Agreement shall terminate upon the termination or expiration of this Agreement, and Spirit shall no longer be provided with fleet hour agreement coverage under the terms of this Agreement.

21.4.1. Upon any termination or expiration of this Agreement, all liabilities and obligations (including payment obligations) that have accrued prior to such termination or expiration (including payment for Excess Work) shall survive.

21.4.2. Should IAE terminate this Agreement under Clause 21.1 or 21.2 hereof, Spirit shall pay to IAE the cost of any and all services which have been, or are in the process of being carried out under the terms of this Agreement which have not been covered by payments made under the FHA plus a surcharge of the lesser of ***** or the maximum allowed by law. Should Spirit terminate this Agreement under any applicable Clauses hereunder, IAE shall return any excess payments for services paid for, but not rendered.

21.4.3. This Clause 21.4 and Clause 27 of this Agreement shall survive any expiration or termination of this Agreement.

21.4.4. IAE’s obligations to indemnity Spirit in accordance with Clauses 14 and 11 hereof and to provide, assign or assist with the enforcement of any unexpired warranties in accordance with Clause 11 shall survive the expiration or termination of this Agreement.

 

  21.5. Partial Termination

If IAE materially delays performance or fails to perform a particular service for a particular engine under this FHA and such failure is inexcusable and beyond any applicable grace period and Spirit is not in material default of any of its obligations under this FHA or the GTA, Spirit may terminate that particular service for that particular engine without penalty. Any amounts due for the particular service for that particular engine shall be pro-rated up to the point of non-performance. Spirit’s rate for the remaining Fleet shall be reevaluated and may be reduced if the new calculation so indicates, but will not increase based on partial termination by Spirit.

If Spirit materially delays performance or fails to perform obligation for a particular engine under this FHA and such failure is inexcusable and beyond any applicable grace period and IAE is not in material default of any of its obligations under this FHA or the GTA, IAE may terminate that particular service for that particular engine without penalty. Any amounts due for the particular service for that particular engine shall be pro-rated up to the point of non-performance. Spirit’s rate for the remaining Fleet shall be reevaluated and may be increased if the new calculation so indicates, but will not decrease based on partial termination by IAE.

Subject:

    Side Letter No. 1 of the V2500-A5 Fleet Hour Agreement between IAE International Aero Engines AG and Spirit Airlines, Inc., dated April 11, 2005

Gentlemen:

We refer to the Fleet Hour Agreement dated April 11, 2005 between IAE International Aero Engines AG (“IAE”) and Spirit Airlines, Inc. (“Spirit”), such contract being hereinafter referred to as the “FHA.” Unless expressly stated to the contrary, and to the extent possible, terms used in this Side Letter No. 1 shall have the same meaning given to them in the FHA.

This Side Letter No. 1 provides for, among other things: A Turn Around Time and Spare Engine Support Guarantee, an Escalation Cap for FHA rates, a special Restoration Shop Visit invoicing arrangement, maintenance center de-selection, an enhanced FHA escalation formula, and payment by IAE for damage to the leased engine bearing engine serial number VI0417. The obligation of IAE to provide any of the benefits pursuant to the terms hereof shall be subject to Spirit not being in default of any of its obligations under the FHA or GTA.

IAE hereby provides the following coverage for the Turn Around Tame and Spare Engine Support Coverage Availability Guarantee (collectively referred to as the “Turn Around Time and Spare Engine Availability Guarantee” or “Guarantee”):

 

1. Turn Around Time and Spare Engine Availability Guarantee

 

  1.1 Turn Around Time: IAE will ensure that the Turn Around Time (“TAT”) of an Eligible Engine from the Maintenance Center shall meet the following requirements provided that Spirit (i) provides lease return dates at lease execution or no later than thirty (30) days from the date of this Side Letter, as appropriate, and (ii) notifies IAE if such lease return dates are amended:

 

  1.1.1 IAE or its Maintenance Center shall complete a full overhaul within a turn around time of ***** days, or a Restoration Shop Visit within ***** days (the “TAT”), whichever is applicable.

 

  1.1.2 The TAT shall start the day after receipt at the Maintenance Center designated by IAE of (a) any Eligible Engine and (b) all necessary

***** Confidential portions of the material have been omitted and filed separately with the Securities and Exchange Commission.

technical documents, including a repair order, and shall end upon the earlier of (i) notification that the Engine is serviceable or (ii) when such Engine is made available for transportation from the Maintenance Center(s). Eligible Engine transportation and time required to undertake and complete Excess Work are not included in the period set out above.

Within two (2) Business Days after receipt of the Engine at the Maintenance Center designated by IAE, IAE shall deliver to Spirit a written notice stating either that (i) the TAT has begun or (ii) the documentation required from Spirit prior to the beginning of the TAT. If no such notice is delivered to Spirit, the TAT shall be deemed to begin one (1) Business Day after delivery of the Engine to the Maintenance Center designated by IAE along with the technical documentation deemed necessary by Spirit and IAE.

 

  1.1.3 Any reasonable technical requests involving issues or changes to the Work Statement or Engine Workscope that could affect the TAT which are delivered in writing by IAE and received by the appropriate representative of Spirit (as designated by Spirit in writing) shall be answered by Spirit within two (2) Business Days after being communicated to such representative in the manner to be agreed between Spirit and IAE. If IAE communicates such request in accordance with this paragraph and the Spirit designated representative does not respond within two (2) Business Days, the TAT will be increased by each day in excess of two (2) Business Days that elapse or prior to receiving a response from Spirit. Any impact on the TAT resulting from this decision shall be promptly advised by IAE.

 

  1.1.4 IAE shall not be liable for exceeding the TAT due to Excusable Delays as such term is defined in Section 12 of the FHA, or for delays directly and solely caused by Spirit. IAE shall promptly notify Spirit when such delays occur or impending delays are likely to occur and shall continue to advise Spirit of new shipping schedules and/or changes thereto.

 

  1.1.5 If IAE fails to meet the TAT set forth in this section for delays that are not Excusable Delays, then IAE shall, for said delayed Eligible Engine, discontinue the charges associated with the following rates: ***** In the event an aircraft lease return is directly and adversely affected by such delay, at Spirit’s request, IAE shall pay Spirit ***** per day for each day (or part thereof) the TAT is exceeded and said aircraft lease continues to be directly and adversely affected. This penalty shall not apply if the lease aircraft return dates are amended to dates that are within sixty (60) days of the affected Eligible Engine shop visit.

 

  1.2 Spare Engine Support Coverage Availability. For Eligible Engines being removed within the continental United States, if IAE fails to provide a

replacement Spare Engine within ***** hours (“US-STAT”) of a written request from Spirit, then IAE, at Spirit’s request, shall pay Spirit ***** per day for each day that is beyond the ***** . IAE shall not be liable for exceeding the ***** due to Excusable Delays as such term is defined in Section 12 of the FHA, or for delays directly and solely caused by Spirit. IAE shall promptly notify Spirit when such delays occur or impending delays are likely to occur and shall continue to advise Spirit of new shipping schedules and/or changes thereto.

 

  1.3 Conditions of Guarantee. The above remedy in Clause 1.2 is applicable only if: (1) Spirit is experiencing an engine caused aircraft on ground situation while being at zero spare engine status caused by V2500-A5 engine related problems, and (2) Spirit is not leasing a Spare Engine through IAE’s emergency lease pool at the time of the request. For the avoidance of doubt, the two conditions in this Clause 1.3 do not apply to Clause 1.1 of the Guarantee.

The cumulative amount of this Guarantee shall in no event exceed ***** over the period of the Guarantee.

The availability of this Guarantee is contingent upon Spirit managing its fleet in accordance with the FHA (including the mutually agreed eMMP).

 

2. Escalation Cap for *****

The FHA Rates set forth in the FHA are subject to escalation in accordance with the formula set out in Exhibit B thereto.

With respect to the FHA Rates, the escalation formula set out in Exhibit B to the FHA when applied to such rates shall be capped at ***** per annum on a cumulative average basis for a period equal to the first ***** from the date of the FHA (the “Capped Period”). The escalation result at the end of the Capped Period will be used as the starting basis for subsequent uncapped escalation calculations for the time periods beginning immediately after the Capped Period up to the end of the FHA.

 

3. Restoration Shop Visit Rate Invoicing:

Notwithstanding anything in Clause 10.1.2. of the FHA to the contrary, IAE shall invoice Spirit and Spirit shall pay at induction of the Restoration Shop Visit an amount equal to ***** of the sum of the escalated FHA Rate multiplied by (i) the Eligible Engine Flight Hours flown by such Eligible Engine since new, or (ii) if the Eligible Engine has had a Restoration Shop Visit, since its last Restoration Shop Visit. The remaining ***** shall be due by Spirit upon completion of the Restoration Shop Visit.

 

4. *****

5. Option to Extend Period of FHA

IAE agrees to provide Spirit with an option to extend the Period of FHA as defined in the FHA by an additional ***** for Spirit’s Eligible Engines. For the avoidance of doubt, this option, if exercised, would apply to as Eligible Engines and can not be used to extend the Period of FHA for individual Eligible Engines. IAE will provide the rates for the extension period based on the same methodology used to calculate the original FHA rates after Spirit informs IAE of its intent to exercise this option. If Spirit decides to exercise this option, Spirit must notify IAE in writing of its selection at least ***** months prior to expiration of the Period of the FHA of the first Eligible Engine to enter into service under the FHA.

 

6. Escalation Formula Enhancement: Resolution of V10417

 

  6.1 IAE agrees to enhance the FHA Escalation Formula attached to Exhibit B to the FHA by changing the Material and Labor ratios from ***** and ***** to ***** and *****. Therefore, Exhibit B to the FHA is hereby deleted in its entirety and replaced with the following new Exhibit B appearing on Schedule 1 attached hereto.

 

  6.2 IAE agrees to pay for the repair of the leased engine bearing manufacturer’s serial number V10417 for damage that occurred while being leased by Spirit pursuant to IAE’s standard terms of business lease. IAE’s agreement to pay for such costs is a one time concession made as a part of a larger negotiation involving the FHA and shall not be construed as obligating IAE to pay for such damage on other leased Engines.

Except as expressly amended by this Side Letter No. 1, all provisions of the FHA remain in full force and effect.

Subject: Amendment No. 1 to Side Letter Agreement No. 5 to the V2500-A5 Fleet Hour Agreement between IAE International Aero Engines AG and Spirit Airlines, Inc. dated April 11, 2005

This Amendment No. 1 amends Clause 2 and Appendix 3 to Side Letter No. 5 with respect to the payment plan for pre-delivery payments relating to a deferred spare engine. Capitalized terms used herein that are not otherwise defined shall have the same meaning given to them in the Contract or Side Letter No. 5. In the event of a conflict between the terms and provisions of this Amendment No. 1 and those of Side Letter No. 5, this Amendment No. 1 shall govern.

 

1. Amendment to Clause 2 (Payment Plan) of Side Letter No. 5

Spirit shall pay the Deferred PDP Amount for the Deferred Spare Engine to IAE in ***** equal monthly installments commencing on ***** and ending on *****, as detailed in Appendix 3 hereto (the “Payment Plan”).

 

2. Amendment to Appendix 3 (Payment Plan) of Side Letter No. 5
