8. Section 3.7 of the Agreement is hereby deleted in its entirety and replaced with the following:

“3.7 Certain Adjustments of Compensation for Carrier Controlled Costs if Contractor purchases any of the 2015 New Aircraft

(a) Except as otherwise expressly provided in this Section 3.7, the Compensation for Carrier Controlled Costs set forth on Table 2 of Schedule 2A and Table 4 of Schedule 2A as of the Effective Date shall not be adjusted.

(b) The financing transaction for each of the 2015 New Aircraft will take the form of a 4(a)(2) private Enhanced Equipment Trust Certificate (EETC) issuance.

(1) The Schedule 2A “ownership rate” payable by United for each of the 2015 New Aircraft under the Agreement will match the principal and interest due under the EETC transaction, including any interest due prior to the delivery of an aircraft, and the upfront fee and commitment fee related to any liquidity facility. Without limiting any of United’s rights or remedies under this Agreement, if required by the financing documentation United will pay all, or a portion of the ownership rate and related amounts to a party other than Contractor subject to documentation acceptable to United relating thereto.

(2) Contractor and United will use commercially reasonable efforts to find an equitable solution if collateralization of a depositary’s interest obligation is required. For the avoidance of doubt a delayed draw option may be mutually agreed as an alternative.

(3) Generally the structural decisions required to complete the issuance will be a joint effort of Contractor and United and when affecting the Schedule 2A “ownership rate” payable by United for each of the 2015 New Aircraft, such structural decisions will be mutually agreed.

(4) Unless otherwise agreed between the parties the structure will include three tranches. The A (first) and B (second) tranches will be purchased by non-United entities with United purchasing the C (third) tranche. The following

5

conditions will apply unless mutually agreed otherwise by the parties:

a. The advance, coupon, term, amortization profile and liquidity facility economics are subject to United’s prior written approval.

b. United will have the right to purchase the more senior certificates at par under default events customary with EETC transactions. In addition, United will have this purchase right under a termination of the Agreement by United due to a material breach of the Agreement by Contractor including, but not limited to, Sections 8.2(a), 8.2(b), 8.2(d), and 8.2(f) of the Agreement

c. In the event of United purchasing all of the more senior certificates as contemplated in the second sentence of paragraph (4)b above, United will also have the right to purchase the Contractor initial investment in the 2015 New Aircraft at an amount representing the unamortized balance at the time of such purchase assuming the initial investment amortizes on a straight line basis over a 12 year term plus any unamortized airworthiness directive expense balance (provided that any airworthiness directive expense balance shall (i) be limited to the cost of parts and direct out-of-pocket costs for third-party labor required to comply with such airworthiness directive, (ii) include only those airworthiness directives in respect of a single aircraft whose initial cost determined in accordance with clause (i) exceeds [***], and (iii) use an amortization period not greater than seven years).

(5) Unless otherwise agreed by United in writing, Contractor will contribute [***] USD toward the purchase price of each of the 2015 New Aircraft which amount will be adjusted based upon the actual purchase price of an aircraft less the amount of debt funded, including the C tranche, for such aircraft.

(c) United will reimburse Contractor for the following actual reasonable costs in accordance with Section 3.6(b)(iii)(A)(15):

(1) Bankers’ fees not to exceed [***] (or other amount as mutually agreed) of the principal value of the bonds issued to investors other than those bonds purchased by United, such banks and the allocation of fees across the banks to be

6

mutually agreed, plus Banker’s reasonable out of pocket expenses in connection with the engagement.

(2) Investors’ legal expenses. For the avoidance of doubt, United’s legal expenses will be for its account.

(3) Fees payable to appraisers and [***] of the rating agency fees, subject to such appraisers being approved by United in writing prior to engagement.

For the avoidance of doubt legal expenses for the representation of Contractor, and [***] of the rating agency fees will be for Contractor’s account Unless otherwise agreed with United, a definitive agreement with investors must be reached by Contractor no later than December 7, 2015. Any extension beyond this date will be subject to United’s prior written consent at the sole discretion of United. Additionally United and Contractor will discuss the continued viability of the above proposed Contractor transaction on or prior to the 5th day of each month until such time the definitive documentation is in place or November 15,2015, subject to a potential extension pursuant to the prior sentence. If during a monthly discussion United reasonably concludes that the Contractor transaction is not viable for any or all of the 2015 New Aircraft, then Contractor will cooperate to assist United to source an alternative form of financing which may include, but not require, United to purchase and own the 2015 New Aircraft (it being acknowledged and agreed that in such event (or, separately, in the event of a Contractor default of its purchase agreement with Embraer for the Block 2 of the 2015 New Aircraft or Block 3 of the 2015 New Aircraft that results in any one or more of such aircraft being purchased by United directly from Embraer), Block 2 of the 2015 New Aircraft and Block 3 of the 2015 New Aircraft will be deemed subject to the provisions of the Second Amendment applicable to Block 1 of the 2015 New Aircraft concurrent with United’s purchase of each of the 2015 New Aircraft).”

9. Schedule 1 is hereby deleted in its entirety and replaced with the revised Schedule 1 attached hereto and incorporated herein by reference.

10. Schedule 1A is hereby deleted in its entirety and replaced with the revised Schedule 1A attached hereto and incorporated herein by reference.

11. Schedule 2A is hereby deleted in its entirety and replaced with the revised Schedule 2A attached hereto and incorporated herein by reference, which includes new Tables 1 and, Table 4.
