Other Events

AerCap Holdings N.V. (“AerCap”) (NYSE: AER) and Genesis Lease Limited (“Genesis”) (NYSE: GLS) announced on September 18, 2009 that their Boards of Directors have approved a definitive agreement under which Genesis will amalgamate with a wholly-owned subsidiary of AerCap in an all share-for-share transaction (the “Amalgamation”). Under the terms of the Agreement and Plan of Amalgamation (the “Amalgamation Agreement”), Genesis shareholders will receive one AerCap ordinary share for every Genesis common share they own. The resulting amalgamated company will continue as a subsidiary of AerCap.

The Amalgamation is subject to approval by Genesis shareholders, satisfaction of customary closing conditions and receipt of any necessary regulatory approvals.

A copy of the Press Release is attached to this Report on Form 6-K as Exhibit 99.1 and is incorporated herein by reference. A copy of the Amalgamation Agreement is attached to this Report on Form 6-K as Exhibit 99.2 and is incorporated herein by reference.

The foregoing summary of the Amalgamation Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Amalgamation Agreement furnished herewith as Exhibit 99.2, which is incorporated herein by reference.

The Amalgamation Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about AerCap, Genesis, their respective subsidiaries, affiliates or businesses or the actual conduct of their respective businesses during the period prior to the consummation of the Amalgamation. Moreover, certain representations and warranties in the Amalgamation Agreement were used for the purpose of allocating risk between AerCap and Genesis, rather than establishing matters of fact. Accordingly, the representations and warranties in the Amalgamation Agreement may not constitute the actual state of facts about AerCap and Genesis. Investors are not third-party beneficiaries under the Amalgamation Agreement (except for the right to receive the amalgamation consideration upon the consummation of the Amalgamation) and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or conditions of AerCap, Genesis or any of their respective subsidiaries or affiliates.
