2.1The Engine Manufacturer hereby confirms to Frontier, the Borrower and the Security Trustee that (i) if the Security Trustee or a Permitted Transferee takes delivery from Airbus of a Subject Aircraft such Security Trustee or Permitted Transferee, as applicable, will receive the Engine Warranties for the Subject Engines installed on such Subject Aircraft and shall assume and accept all of the rights, obligations, liabilities, exceptions, and limitations with respect to such Engine Warranties with respect to such Subject Engines and (ii) it consents to the collateral assignment by the Borrower to the Security Trustee of its rights under this Agreement, and agrees that the Security Trustee’s rights under Section 2.1(i) and such assignment shall not give rise to any duties or obligations whatsoever on the part of the Security Trustee owing to the

Engine Manufacturer except (i) for the Security Trustee’s agreement that in exercising any right under the this Agreement with respect to such Engines, or in making any claim with respect to such Engines, the terms and conditions of such Engine Purchase Agreement relating to the Engines and the Engine Warranties shall apply to and be binding upon the Security Trustee to the same extent as Frontier and/or the Borrower and (ii) as otherwise expressly provided in this Agreement, including without limitation pursuant to Section 5.2 of this Agreement.

2.2The Security Trustee acknowledges and agrees, in relation to each Subject Aircraft, that Frontier will continue to have the right to receive any applicable credit or other allowance for the Subject Engines installed on such Subject Aircraft (each of such two Subject Engines, a “Subject Engine Set”) that is available under the Engine Purchase Agreement and the right to exercise any applicable warranties for such Subject Engine Set (or the relevant individual Subject Engine) under the Engine Purchase Agreement until such time as the Security Trustee has served a Step-In Notice in accordance with the Step In Agreement.

3.1 IAE hereby confirms that the Introductory Assistance Credits, as provided in the table below and as further described below, corresponding with a given Subject Aircraft identified in the such table (such amount, [***], the “Introductory Assistance Credit” or “Credit”) shall be made available by IAE to the Security Trustee or the Permitted Transferee, as the case may be, upon delivery and acceptance of such applicable Subject Aircraft by such person, and subject to Section 3.6 below. The Credit for each Subject Aircraft, and the corresponding Unit Base Price per Subject Engine Set, as provided in the table below, [***]. For the avoidance of doubt, the Introductory Assistance Credits set forth in the table below shall apply solely to the Subject Aircraft.

3.2IAE will issue the Introductory Assistance Credit directly to Airbus and will instruct Airbus, in writing, to credit such Introductory Assistance Credit against the purchase price for the applicable Subject Aircraft. IAE shall be entitled to rely on a notice from the Security Trustee (or the Permitted Transferee, if applicable) that the Security Trustee or such Permitted Transferee is entitled to take delivery of a Subject Aircraft and shall have no liability for any such reliance.

3.3The Security Trustee agrees and, if applicable will cause the Permitted Transferee to agree, that the Credit for any applicable Subject Aircraft shall not vest in Airbus nor be applied toward payment of the purchase price for such Subject Aircraft until acceptance by and delivery of such Subject Aircraft to the Security Trustee or Permitted Transferee, as the case may be; provided that the parties agree that the assignment of the Credit shall occur sufficiently in advance of delivery to allow for timely delivery and shall take final effect at delivery to and acceptance by the Security Trustee or Permitted Transferee of the respective Subject Aircraft. In the event that the Security Trustee or Permitted Transferee does not accept delivery of any Subject Aircraft, the Security Trustee or Permitted Transferee, as applicable, shall have its management team induce Airbus’ management to refund the Credit to IAE.

3.4Frontier hereby acknowledges and agrees that payment of the Credit by IAE in respect of the applicable Subject Aircraft pursuant to this Section 3 of this Agreement will relieve and release IAE of any and all obligations to pay the Credit with respect to such Subject Aircraft under the Engine Purchase Agreement. The parties further agree IAE shall have no liability to any other party, or any Permitted Transferee, for paying a Credit in respect of the applicable Subject Aircraft pursuant to this Section 3 or for relying on any notice provided by the Security Trustee or any Permitted Transferee of its right to take delivery of a Subject Aircraft. Save to the extent expressly provided in this Agreement, all other terms of the Engine Purchase Agreement (including, without limitation, the Engine Warranties) shall continue to apply and shall have full force and effect between the Frontier and IAE.

3.5Each of Frontier, Borrower, the Security Trustee or the Permitted Transferee, as applicable, will ensure its compliance with any, and all, requirements (including but not limited to reporting and approval requirements) of any applicable currency control or other law, rule, or regulation relating to an Introductory Assistance Credit issued under this Agreement.

3.6The Security Trustee acknowledges and agrees that IAE’s obligation to pay the Credit with respect to a Subject Aircraft to be purchased by the Security Trustee or a Permitted Transferee (as provided above) shall be subject to the Security Trustee (or Permitted Transferee, if applicable) providing prior written notice to IAE that the Security Trustee (or Permitted Transferee, if applicable) has exercised its right to purchase such Subject Aircraft pursuant to the Step In Agreement and is entitled to purchase the Aircraft under the Assigned Purchase Agreement (the “Purchase Notice”). IAE shall be entitled to (and Frontier and Borrower hereby authorize IAE to) rely on the information contained in any such Purchase Notice from the Security Trustee (or Permitted Transferee, if applicable). The Security Trustee (or Permitted Transferee, if applicable) shall provide the Purchase Notice to IAE as soon as reasonably practicable after such person has acquired an unfettered right to purchase
