PRESS RELEASE

FOR IMMEDIATE RELEASE

AerCap and Genesis Lease to Merge in an All Share Transaction

Genesis’ modern aircraft portfolio and strong generation of free cash flow combined with AerCap’s strong contracted growth with a substantial order book of the most fuel-efficient, state-of-the-art aircraft will create the world’s leading independent aircraft leasing company with total assets of approximately $8 billion

Amsterdam, Netherlands/Shannon, Ireland; September 18, 2009 — AerCap Holdings N.V. (“AerCap”) (NYSE: AER) and Genesis Lease Limited (“Genesis”) (NYSE: GLS) today announced that their Boards of Directors have approved a definitive agreement under which AerCap and Genesis will merge in an all share-for-share transaction. Under the terms of the amalgamation agreement, Genesis shareholders will receive one AerCap ordinary share for every Genesis common share they own.

Genesis will become a wholly-owned subsidiary of AerCap. AerCap’s CEO Klaus Heinemann and CFO Keith Helming will lead the combined company, which will retain the name AerCap. Three directors from Genesis will be nominated for election to the Board of Directors of

AerCap at an extraordinary general meeting of AerCap shareholders to be called and held shortly after the consummation of the transaction.

Based on Genesis’ balance sheet, the transaction has a value of $1.75 billion and, based on the closing stock price for AerCap Holdings N.V. ordinary shares on Thursday, September 17, 2009, the share-for-share consideration has a value of $8.81 per Genesis ADS (each ADS representing one Genesis common share). The one-for-one exchange ratio represents an average premium to Genesis shareholders of 45% based on the daily closing prices of Genesis ADS and AerCap ordinary shares during the 30 day trading period from July 31, 2009 to September 11, 2009. Upon closing of the transaction, Genesis shareholders are expected to own approximately 29% of the combined company.

The transaction is subject to approval by Genesis shareholders, satisfaction of customary closing conditions and receipt of any necessary regulatory approvals. The transaction is expected to close in the fourth quarter of 2009.

AerCap’s CEO Klaus Heinemann commented, “The merger of Genesis and AerCap enhances the cash generation of the combined company in the current environment to pursue our growth objectives and capitalize on opportunities as the market recovers. Like AerCap, Genesis boasts the most modern, fuel-efficient and in-high-demand jets that are fully financed and on lease to a diverse operator base, including many new customers not currently in the AerCap portfolio. The similarity of our respective aircraft portfolios, combined with AerCap’s substantial order book, make this an attractive transaction for all stakeholders.

Following this transaction, AerCap will become the leading independent franchise within the global aircraft leasing sector, with 116 airline customers in 50 countries and a lease portfolio currently valued at $6 billion, with another 83 aircraft on order or under purchase contract.”

John McMahon, Chairman & CEO of Genesis added, “Genesis’ board and management are committed to enhancing shareholder value. This transaction, through the solid profitability and strong cash flows of Genesis, combined with AerCap’s scale and order book, which is nearly all placed, provides our shareholders with a significant and immediate premium to recent stock trading levels and positions them to participate in enhanced earnings and business growth in the future.”

As part of the agreement, GE Capital Aviation Services (GECAS), which has acted as servicer for Genesis’ portfolio, will continue to provide most asset management services for the Genesis fleet in the near term. GECAS has, however, agreed with AerCap a means to terminate early the GECAS services at AerCap’s option. Additionally, AerCap has signed a letter of intent to purchase 13 aircraft from GECAS. The purchase of two aircraft is expected to occur by the end of September 2009 and the purchase of the remaining aircraft is expected to take place after and is subject to the closing of the transaction announced today.

The combined company will have a total fleet of 358 commercial aircraft and 83 engines that are either owned, on order, under contract or letter of intent, or managed. The average age of its owned aircraft fleet is 6.6 years.
