CALCULATION OF REGISTRATION FEE

(1)

Represents, together with the 34,346,596 shares previously registered under the F-4 filed on October 6, 2009 (Registration No. 333-162365), the maximum number of AerCap Holdings N.V. ("AerCap") ordinary shares to be issued to shareholders of Genesis Lease Limited ("Genesis") in connection with a business combination between the two companies, assuming that no Genesis shareholder seeks appraisal of its shares under Bermuda law in connection with such transaction. To the extent that any AerCap ordinary shares are not issued to Genesis shareholders that seek appraisal of their shares, such AerCap ordinary shares will be issued to persons who may be deemed to be underwriters pursuant to Rule 154(c) of the Securities Act and are being registered hereunder to cover resales from time to time after issuance to such persons, subject to the maximum number of shares that such persons have agreed to acquire pursuant to arrangements between AerCap and such persons as more fully described in our currently effective registration statement.

(2)

Pursuant to Rule 457(c) and Rule 457(f) of the Securities Act, and solely for the purpose of calculating the registration fee, the proposed maximum offering price of $31,840.92 is equal to the product of (a) a market value of $11.01 per share of the American Depositary Shares of Genesis ("Genesis ADSs"), corresponding to the average of the high and low prices for the Genesis ADSs on the New York Stock Exchange on March 18, 2010, and (b) 2,892, the number of AerCap ordinary shares being registered. Each Genesis ADS represents one Genesis common share, par value $0.001 per share.

(3)

Computed in accordance with Rule 457(f) of the Securities Act by multiplying the proposed maximum offering price by 0.00007130.
