that any such offer, sale, assignment, transfer, participation or other disposition during the occurrence and continuation of an Event of Default shall not be subject to indemnification unless it is made in accordance with the Indenture and

 15 

Participation Agreement (2020-1 EETC) 

N626QX 













 (xi) any Claim to the extent such Claim is incurred on account of or
asserted as a result of (A) any “prohibited transaction” within the meaning of Section 406 of ERISA or Section 4975 of the Code or any foreign, federal, state or local law which is substantially similar to the
prohibited transaction provisions of Section 406 of ERISA or Section 4975 of the Code (“Similar Law”) or (B) any breach of fiduciary duty under ERISA; 

(xii) any Claim to the extent such Claim is attributable to one or more of the other aircraft financed through the offering of
Pass Through Certificates (in the event of doubt, any Claim shall be allocated between the Aircraft and such other aircraft in the same proportion that the then outstanding Equipment Notes bear to the then outstanding equipment notes issued with
respect to the other aircraft and held by Pass Through Trustees); 
 (xiii) any Claim to the extent such Claim is
attributable to any amount which any Indemnitee expressly agrees shall not be paid by, borne by, or reimbursed by Company;

(xv) any Claim to the extent such Claim is attributable to the offer or sale by an Indemnitee (or any member of such
Indemnitee’s Related Indemnitee Group) of any interest in the Aircraft, the Equipment Notes, the Pass Through Certificates, or any similar interest, in violation of the Securities Act or other applicable federal, state or foreign securities
laws (other than any thereof caused by acts or omissions of Company or any of its affiliates). 
 (e) Insured Claims.
In the case of any Claim indemnified by Company hereunder that is covered by a policy of insurance maintained by Company, each Indemnitee agrees to cooperate, at Company’s expense, with the insurers in the exercise of their rights to
investigate, defend and compromise such Claim. 
 (f) Claims Procedure. An Indemnitee shall promptly notify Company of
any Claim as to which indemnification is sought. The failure to provide such prompt notice shall not release Company from any of its obligations to indemnify hereunder except to the extent that Company is prejudiced by such failure or


  
 16 

Participation Agreement (2020-1 EETC) 

N626QX 













 
Company’s indemnification obligations are increased as a result of such failure (in which event Company shall not be responsible for such additional indemnification obligations). Such
Indemnitee shall promptly submit to Company all additional information in such Indemnitee’s possession to substantiate such Claim as Company reasonably requests. Subject to the rights of Company’s insurers, Company may, at its sole cost
and expense, investigate any Claim, and may in its sole discretion defend or compromise any Claim. At Company’s expense, any Indemnitee shall cooperate with all reasonable requests of Company in connection therewith. Such Indemnitee shall not
enter into a settlement or other compromise with respect to any Claim without the prior written consent of Company, which consent shall not be unreasonably withheld or delayed, unless such Indemnitee waives its right to be indemnified with respect
to such Claim. Where Company or its insurers undertake the defense of an Indemnitee with respect to a Claim, no additional legal fees or expenses of such Indemnitee in connection with the defense of such Claim shall be indemnified hereunder unless
such fees or expenses were incurred at the written request of Company or such insurers. Subject to the requirements of any policy of insurance, an Indemnitee may participate at its own expense in any judicial proceeding controlled by Company
pursuant to the preceding provisions; provided that such party’s participation does not, in the opinion of outside counsel appointed by Company or its insurers to conduct such proceedings, interfere with such control. Such participation
shall not constitute a waiver of the indemnification provided in this Section 4.02. Notwithstanding anything to the contrary contained herein, Company shall not under any circumstances be liable for the fees and expenses of more than one
counsel for all Indemnitees with respect to any one Claim. Notwithstanding anything to the contrary contained herein, an Indemnitee shall not under any circumstances be required or deemed to be required to contest any Claim or to assume
responsibility for or control of any judicial proceeding with respect thereto. Company will provide the relevant Indemnitee with such information not within the control of such Indemnitee, as is in Company’s control or is reasonably available
to Company, which such Indemnitee may reasonably request and will otherwise cooperate with such Indemnitee so as to enable such Indemnitee to fulfill its obligations under this Section. If an Indemnitee is not a party to this Agreement, Company may
require such Indemnitee to agree in writing to the terms of this Section 4.02 and Section 7.10 of this Agreement prior to making any payment to such Indemnitee under this Section 4.02. 

(g) Subrogation. To the extent that a Claim is in fact paid in full by Company or its insurer, Company or such insurer
(as the case may be) shall, without any further action, be subrogated to the rights and remedies of the Indemnitee on whose behalf such Claim was paid with respect to the transaction or event giving rise to such Claim. Such Indemnitee shall give
such further assurances or agreements and shall cooperate with Company or such insurer, as 

  
 17 

Participation Agreement (2020-1 EETC) 

N626QX 













 
the case may be, to permit Company or such insurer to pursue such rights and remedies, if any, to the extent reasonably requested by Company. So long as no Event of Default has occurred and is
continuing, if an Indemnitee receives any payment, in whole or in part, from any party other than Company or its insurers with respect to any Claim paid by Company or its insurers, it shall promptly pay over to Company the amount received (but not
an amount in excess of the amount Company or any of its insurers has paid in respect of such Claim). Any amount referred to in the preceding sentence that is payable to Company shall not be paid to Company, or, if it has been previously paid
directly to Company, shall not be retained by Company, if at the time of such payment an Event of Default has occurred and is continuing, but shall be paid to and held by Loan Trustee as security for the obligations of Company under the Operative
Documents. If Company agrees, such amount payable shall be applied against Company’s obligations thereunder when and as they become due and payable. At such time as such Event of Default is no longer continuing, such amount, to the extent not
previously so applied against Company’s obligations, shall be paid to Company. 
 (h) No Guaranty. Nothing set
forth in this Section 4.02 constitutes a guarantee by Company that the Aircraft at any time will have any particular value, useful life or residual value. 

(i) Payments; Interest. Any amount payable to any Indemnitee on account of a Claim shall be paid within 30 days after
receipt by Company of a written demand therefor from such Indemnitee accompanied by a written statement describing in reasonable detail the Claims that are the subject of and basis for such indemnity and the computation of the amount payable. Any
payments made pursuant to this Section 4.02 directly to an Indemnitee or to Company, as the case may be, shall be made in immediately available funds at such bank or to such account as is specified by the payee in written directions to the
payor or, if no such directions are given, by check of the payor payable to the order of the payee and mailed to the payee by certified mail, return receipt requested, postage prepaid to its address referred to in Section 7.01. To the extent
permitted by applicable law, interest at the Past Due Rate shall be paid, on demand, on any amount or indemnity not paid when due pursuant to this Section 4.02 until the same is paid. Such interest shall be paid in the same manner as the unpaid
amount in respect of which such interest is due. 
 (j) Tax Deduction or Credit. If, by reason of any payment made to
or for the account of any Indemnitee by Company, or by reason of any Claim of any Indemnitee paid or indemnified against by Company, in each case pursuant to Section 4.02, such Indemnitee realizes a Tax deduction or credit not previously taken
into account in computing such payment, such Indemnitee shall promptly pay to Company an amount equal to the sum of (i) the actual reduction in Taxes realized by such Indemnitee which is attributable to such deduction or credit, and


  
 18 

Participation Agreement (2020-1 EETC) 

N626QX 













 
(ii) the actual reduction in Taxes realized by such Indemnitee as a result of any payment made by such Indemnitee pursuant to this sentence; provided that the amount payable by
such Indemnitee pursuant to this sentence shall not exceed the sum of all amounts previously paid by Company to such Indemnitee pursuant to this Section 4.02; provided, further, that any such excess shall be carried forward and
applied to reduce pro tanto any subsequent obligations of Company to make payments to such Indemnitee pursuant to Section 4.02. If such Tax deduction or credit is subsequently disallowed or lost, upon written notice from the Indemnitee
Company shall promptly repay all amounts paid to it pursuant to this Section 4.02(j) in respect of such disallowed or lost deduction or credit. If, at the time an amount would otherwise be payable to Company under this Section 4.02(j), any
Event of Default shall have occurred and be continuing, such amount shall be held by the relevant Indemnitee as security for the obligations of Company under the Operative Documents. At such time as no Event of Default is continuing, such amount or
portion thereof shall be applied to offset Company’s outstanding obligations under the Operative Documents and any remaining amount after such application shall be paid to Company.
