Strategic Rationale for ILFC Acquisition AerCap's acquisition of ILFC will create the leading global franchise in the aircraft leasing industry The combination presents a unique strategic opportunity to bring together the outstanding and experienced personnel from both companies, along with a diverse portfolio of modern aircraft and customers, coupled with an attractive order book comprised of state-of-the-art aircraft These combined resources along with a strong liquidity profile provide the opportunity to drive high levels of stable long term profitability and cash flows for the benefit of all our stakeholders The transaction provides immediate value creation for AerCap shareholders with run-rate pro forma earnings per share of $4.00+ Meaningful opportunities exist to better optimize ILFC's fleet, stemming from AerCap's position as one of the most active aircraft portfolio managers in the world, and the ability to utilize AeroTurbine’s capabilities The aircraft leasing business is very scalable and the transaction provides substantial opportunities to produce meaningful cost savings and operating efficiencies Relocation of ILFC's assets is necessary to align the assets with the operating platform of the Combined Company as AerCap already operates in Ireland. The transfer of assets will produce a reduction in the tax expense of the Combined Company based on the Irish tax rate The acquisition will be prudently capitalized with a combination of debt and equity, providing solid support for contracted orders and rapid deleveraging 6

Debt/Equity Ratio of Combined Company 20 AerCap has historically maintained a conservative capital structure and has a proven track record of de-leveraging Initial debt/equity ratio is higher than targeted leverage due to the expected write-down of ILFC’s equity under purchase accounting Robust earnings from the Combined Company will rapidly reduce leverage back to targeted levels Within two years of closing, the Debt/Equity ratio is expected to be ~4 to 1, and ~3 to 1 within four to five years Leverage is expected to rapidly decline to targeted levels ~85% of the Combined Company’s next three-years’ lease revenue is already contracted ~5.5x ~4x ~3x 0 1 2 3 4 5 6 Initial Within ~2 Years Within ~4-5 Years

Capital Management We expect the Combined Company to have deep access to all funding markets Combined, AerCap and ILFC have raised over $39 billion of financing in the last several years – many times the expected financing need of the Combined Company over the next few years The Combined Company has very manageable capital expenditures of approximately $3 billion per annum over the next 3 years for deliveries of new aircraft We also expect to sell approximately $1 billion of aircraft per annum, the level of sales AerCap has executed on a stand-alone basis Given the Combined Company's access to the global financing markets and our strong contracted operating cash flow, we view the capital requirements of the Combined Company as very manageable 27
