Re: Offer of Employment with Sumisho

In anticipation of completion of the acquisition of Air Lease Corporation by Sumitomo Corporation, SMBC Aviation Capital, Apollo and Brookfield, we are very pleased to make an offer in principle to you for the role of Executive Vice President and Chief Financial Officer of Sumisho Air Lease Corporation.

This offer in principle is subject to the completion of the transaction contemplated by the Agreement and Plan of Merger dated as of September 1, 2025, among Air Lease Corporation, Gladiatora Designated Activity Company (now Sumisho Air Lease Corporation DAC) and Takeoff Merger Sub Inc. (the “Transaction”). Following completion of the Transaction, your employer will be Sumisho Air Lease Corporation (“Sumisho” or the “Company”), and you will receive a formal offer letter memorializing and confirming the terms and conditions of your employment.


Role						Chief Financial Officer of Sumisho Air Lease Corporation. The role will be based in Los Angeles, CA at the current principal offices of Air Lease Corporation at 2000 Avenue of the Stars, Suite 1000N, Los Angeles, CA 90067.

Commencement Date						Your role as CFO will become effective immediately on completion of the Transaction, which is anticipated to be on or about April 8, 2026.

Salary						You will receive a base salary of US $700,000 per annum. Salary will be paid in equal installments consistent with the Company’s current payroll processes.
Bonus						You will be eligible to participate in the Sumisho Air Lease Corporation annual performance-based discretionary bonus plan that runs each financial year (from January to December). Your annual target bonus under this plan for this role is 100% of your prevailing base salary (the “Target Bonus”). You will be eligible to participate in the Sumisho Air Lease Corporation Annual Cash Long Term Incentive Plan (LTIP), details of which remain subject to approval by the Board of Directors. Notwithstanding, your annual target grant under this LTIP plan is 45% of annual total target cash compensation (annual base salary plus Target Bonus) for the financial/calendar year, paid pro rata (33%, 33%, 34%) over a three-year period, and subject to performance against business targets as set by Sumisho’s Board of Directors (or its Remuneration committee). Such LTIP awards are anticipated to provide similar termination and resignation protection terms i.e. termination without cause and resignation with good reason, as provided under the time-based RSU award agreement issued in 2025 under the ALC 2023 Equity Incentive Plan. For both the Target Bonus and LTIP, unless otherwise stated in the plan documents or in the ALC 2025 Cash Bonus Plan (which provides certain protections that may be triggered upon termination or resignation), in order to be eligible for that financial year’s payment, you must be a current employee of Sumisho at the time payment is due and payable. 1

1 From April 8, 2026, through December 31, 2026, any bonus payments (Target or LTIP) to which you are entitled will be pro-rated based on the actual number of days employed by Sumisho and, consistent with state and federal law, subject to any applicable withholding taxes and other authorized deductions.
