The Equipment Notes (other than the Series B Equipment Notes and the Additional Series Equipment Notes) shall be dated the Closing Date, shall be issued in a single series consisting of Series A and in the maturities and principal amounts and shall bear interest as specified in Schedule I hereto. The Series B Equipment Notes shall be dated the Class B Issuance Date and shall be issued in the maturities and principal amounts and shall bear interest as specified in Schedule I hereto. On the Closing Date, the Series A Equipment Notes shall be issued to the Subordination Agent on behalf of the Class A Pass Through Trustee under the Pass Through Trust Agreement with respect to the Class A Pass Through Trust, and on the Class B Issuance Date, the Series B Equipment Notes shall be issued to the Subordination Agent on behalf of the Class B Pass Through Trustee under the Pass Through Trust Agreement with respect to the Class B Pass Through Trust. In addition to the foregoing, Owner shall have the option to issue one or more separate series of Additional Series Equipment Notes at any time and from time to time at or after the Issuance Date, subject to the terms of Section 6.1.5 of the Note Purchase Agreement, Section 6.1.5 of the Class B Note Purchase Agreement and Section 9.1(d) of the Intercreditor Agreement. If more than one series of Additional Series Equipment Notes are so issued, each such series shall have a different designation such as, for example, “Series C” and “Series D”, shall be dated the date of original issuance thereof and shall have such maturities, principal amounts and interest rates as specified in an amendment to this Trust Indenture. The Equipment Notes shall be issued in registered form only. The Equipment Notes shall be issued in denominations of $1,000 and integral multiples thereof, except that one Equipment Note of each Series may be in an amount that is not an integral multiple of $1,000.

Each Equipment Note shall bear interest at the applicable Debt Rate (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on the unpaid

Original Amount thereof from time to time outstanding. Accrued interest shall be payable in arrears (i) in the case of the Series A Equipment Notes, on January 15, 2021, and on January 15, April 15, July 15 and October 15 thereafter until maturity, and (ii) in the case of the Series B Equipment Notes, on April 15, 2021, and on January 15, April 15, July 15 and October 15 thereafter until maturity. The Original Amount of each Equipment Note shall be payable on the dates and in the installments equal to the corresponding percentage of the Original Amount as set forth in Schedule I hereto for the applicable Series (as amended, in the case of any Additional Series, at the time of original issuance of such Additional Series) which shall be attached as Schedule I to such Equipment Notes (which shall be adjusted in accordance with Section 2.05 hereof after application of any partial redemptions made prior to the date that any such installment is due). Notwithstanding the foregoing, the final payment made under each Equipment Note shall be in an amount sufficient to discharge in full the unpaid Original Amount and all accrued and unpaid interest on, and any other amounts due under, such Equipment Note. Each Equipment Note shall bear interest, payable on demand, at the Payment Due Rate (calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any part of the Original Amount, Make-Whole Amount, if any, and, to the extent permitted by applicable Law, interest and any other amounts payable thereunder not paid when due for any period during which the same shall be overdue, in each case for the period the same is overdue. Amounts under any Equipment Note shall be overdue if not paid when due (whether at stated maturity, by acceleration or otherwise). Notwithstanding anything to the contrary contained herein, if any date on which a payment under any Equipment Note becomes due and payable is not a Business Day then such payment shall not be made on such scheduled date but shall be made on the next

succeeding Business Day and if such payment is made on such next succeeding Business Day, no interest shall accrue on the amount of such payment during such extension.

The Owner agrees to pay to the Mortgagee for distribution in accordance with Section 3.04 hereof: (a)(i) to the extent not payable (whether or not in fact paid) under Section 8.2.2 of the Note Purchase Agreement or Section 8.2.2 of the Class B Note Purchase Agreement, an amount equal to the fees payable to the applicable Liquidity Provider under Section 2.03 of each Liquidity Facility and the related Fee Letter (as defined in the Intercreditor Agreement); (ii) the amount equal to interest on any Downgrade Advance (other than any Applied Downgrade Advance) payable under Section 3.07 of each Liquidity Facility minus Investment Earnings from such Downgrade Advance; (iii) the amount equal to interest on any Non-Extension Advance (other than any Applied Non-Extension Advance) payable under Section 3.07 of each Liquidity Facility minus Investment Earnings from such Non-Extension Advance; (iv) the amount equal to interest on any Special Termination Advance (other than any Applied Special Termination Advance) payable under Section 3.07 of each Liquidity Facility minus Investment Earnings from such Special Termination Advance; (v) if any payment default shall have occurred and be continuing with respect to interest on any Series A Equipment Notes or Series B Equipment Notes, the excess, if any, of (1) an amount equal to interest on any Unpaid Advance, Applied Downgrade Advance, Applied Non-Extension Advance or Applied Special Termination Advance payable under Section 3.07 of each Liquidity Facility over (2) the sum of Investment Earnings from any Final Advance plus any amount of interest at the Payment Due Rate actually payable (whether or not in fact paid) by Owner on the overdue scheduled interest on the Equipment Notes in respect of which such Unpaid Advance, Applied Downgrade Advance, Applied Non-Extension Advance or Applied Special Termination Advance was made by the applicable Liquidity Provider;

and (vi) any other amounts owed to the applicable Liquidity Provider by the Subordination Agent as borrower under each Liquidity Facility other than amounts due as repayment of advances thereunder or as interest on such advances, except to the extent payable pursuant to clause (ii), (iii), (iv) or (v) above, (b) all compensation and reimbursement of expenses, disbursements and advances payable by Owner under the Pass Through Trust Agreements and (c) all compensation and reimbursement of expenses and disbursements payable to the Subordination Agent under the Intercreditor Agreement except with respect to any income or franchise taxes incurred by the Subordination Agent in connection with the transactions contemplated by the Intercreditor Agreement.

The Equipment Notes shall be executed on behalf of the Owner by one of its authorized officers. Equipment Notes bearing the signatures of individuals who were at any time the proper officers of the Owner shall bind the Owner, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Equipment Notes or did not hold such offices at the respective dates of such Equipment Notes. The Owner may from time to time execute and deliver Equipment Notes with respect to the Aircraft to the Mortgagee for authentication upon original issue and such Equipment Notes shall thereupon be authenticated and delivered by the Mortgagee upon the written request of the Owner signed by an authorized officer of the Owner. No Equipment Note shall be secured by or entitled to any benefit under this Trust Indenture or any other Security Agreement or be

valid or obligatory for any purposes, unless there appears on such Equipment Note a certificate of authentication in the form provided for herein executed by the Mortgagee by the manual signature of one of its authorized officers and such certificate upon any Equipment Notes be conclusive evidence, and the only evidence, that such Equipment Note has been duly authenticated and delivered hereunder.
