(ix) any Claim to the extent such Claim is payable or borne by (A) the Company pursuant to any indemnification, compensation or reimbursement provision of any other Operative Document or any Pass Through Document or (B) a Person other than the Company pursuant to any provision of any Operative Document or any Pass Through Document;

Participation Agreement (Spirit 2015-1 EETC)

(e) Insured Claims. In the case of any Claim indemnified by the Company hereunder that is covered by a policy of insurance maintained by the Company, each Indemnitee agrees to cooperate, at the 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 the Company of any Claim as to which indemnification is sought. The failure to provide such prompt notice shall not release the Company from any of its obligations to indemnify hereunder except to the extent that the Company is prejudiced by such failure or the Company’s indemnification obligations are increased as a result of such failure (in which event the Company shall not be responsible for such additional indemnification obligations). Such Indemnitee shall promptly submit to the Company all additional information in such Indemnitee’s possession to substantiate such Claim as the Company reasonably requests. Subject to the rights of the Company’s insurers, the Company may, at its sole cost and expense, investigate any Claim, and may in its sole discretion defend or compromise any Claim. At the Company’s expense, any Indemnitee shall cooperate with all reasonable requests of the 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 the 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 the 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 the 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 the Company pursuant to the preceding provisions; provided that such party’s

Participation Agreement (Spirit 2015-1 EETC)

[Reg. No.]

participation does not, in the opinion of outside counsel appointed by the 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, the 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. The Company will provide the relevant Indemnitee with such information not within the control of such Indemnitee, as is in the Company’s control or is reasonably available to the 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 4.02. If an Indemnitee is not a party to this Agreement, the 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 the Company or its insurer, the 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 the Company or such insurer, as the case may be, to permit the Company or such insurer to pursue such rights and remedies, if any, to the extent reasonably requested by the 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 the Company or its insurers with respect to any Claim paid by the Company or its insurers, it shall promptly pay over to the Company the amount received (but not an amount in excess of the amount the 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 the Company shall not be paid to the Company, or, if it has been previously paid directly to the Company, shall not be retained by the 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 the Loan Trustee as security for the obligations of the Company under the Operative Documents. If the Company agrees, such amount payable shall be applied against the 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 the Company’s obligations, shall be paid to the Company.

Participation Agreement (Spirit 2015-1 EETC)

[Reg. No.]

(h) No Guaranty. Nothing set forth in this Section 4.02 constitutes a guarantee by the 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 the 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 the 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 the Company, or by reason of any Claim of any Indemnitee paid or indemnified against by the Company, in each case pursuant to this 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 the 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 (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 the 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 the Company to make payments to such Indemnitee pursuant to this Section 4.02. If such Tax deduction or credit is subsequently disallowed or lost, upon written notice from the Indemnitee the 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 the 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 the 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 the Company’s outstanding obligations under the Operative Documents and any remaining amount after such application shall be paid to the Company.
