Explanatory Statement

This Amendment No. 10 (“Amendment No. 10”) amends and supplements the statement on Schedule 13D filed by Marubeni Corporation (“Marubeni”) on June 17, 2013, as amended by Amendments Nos. 1 through 9 filed jointly by Marubeni, Marubeni Aviation Corporation (“MAC”) and Marubeni Aviation Holding Coöperatief U.A. (“MHC” and together with Marubeni and MAC, the “Reporting Persons”). The Schedule 13D, as so amended (the “Schedule 13D”), relates to the common shares, par value $0.01 per share (the “Common Shares”), of Aircastle Limited, a Bermuda exempted company (the “Issuer”). Unless otherwise indicated, each capitalized term used but not defined herein has the meaning assigned to such term in the Schedule 13D.

This Amendment No. 10 is being filed jointly by the Reporting Persons.

Item 4. Purpose of Transaction

Item 4 is hereby supplemented by the addition of the following:

On August 26, 2015, MHC and Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Merrill Lynch”) agreed to amend the Stock Purchase Plan Engagement Agreement dated February 19, 2015 (the “2015 Purchase Plan”). The amendment increases the total amount of Common Shares that can be acquired under the 2015 Purchase Plan to an amount that, together with the Common Shares already owned by the Reporting Persons, does not exceed 27.5% of the Issuer’s issued and outstanding Common Shares. The previous cap was 24.99% of the Issuer’s issued and outstanding Common Shares. The Reporting Persons expect that purchases of Common Shares will be made for MHC’s account pursuant to the 2015 Purchase Plan.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Item 6 is hereby supplemented by the addition of the following:

On August 26, 2015, MHC and Merrill Lynch agreed to amend the 2015 Purchase Plan. The amendment increases the total amount of Common Shares that can be acquired under the 2015 Purchase Plan to an amount that, together with the Common Shares already owned by the Reporting Persons, does not exceed 27.5% of the Issuer’s issued and outstanding Common Shares. The previous cap was 24.99% of the Issuer’s issued and outstanding Common Shares. On the date of the amendment, MHC was not in possession of any material nonpublic information regarding Issuer or its Common Shares and its decision to amend the 2015 Purchase Plan was made in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. MHC requested and was granted approval by the Issuer to amend the 2015 Purchase Plan in the manner described in accordance with the Issuer’s Amended and Restated Trading Compliance Program.

Re: Amendment of Stock Purchase Plan Engagement Agreement

Ladies and Gentlemen:

Reference is made to the Stock Purchase Plan Engagement Agreement (the “Purchase Agreement”) dated as of February 19, 2015 between Marubeni Aviation Holding Coöperatief U.A. (the “Purchaser”) and Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Broker”).

Purchaser desires to amend the Purchase Agreement to increase the total amount of Securities permitted to be purchased in Annex A of the Purchase Agreement to 27.5% of Aircastle Ltd. total shares outstanding as calculated per Aircastle Ltd.’s latest quarterly filing. Therefore, the opening paragraph of Annex A is hereby amended to replace the phrase “greater than 24.99% of Aircastle Ltd. total shares” with the phrase “greater than 27.5% of Aircastle Ltd. total shares”.

In connection with the amendment of the Purchase Agreement, the Purchaser hereby represents and warrants to Broker that on the date hereof the Purchaser is not aware of any material nonpublic information regarding the Company or its Securities, and that its decision to amend the Purchase Agreement was made in good faith and not as a part of a plan or scheme to evade the prohibitions of Rule 10b-5 under the Securities Exchange Act of 1934, as amended. Further, Purchaser hereby represents and warrants that this amendment has been consented to by Aircastle Limited in accordance with its Amended and Restated Insider Trading Compliance Program.

Very truly yours,
