EXECUTED BY ERICKSON AIR-CRANE INCORPORATED

WHEREAS, the Maker has filed a registration statement on Form S-1 under the Securities Act of 1933, as amended, with the Securities and Exchange Commission for the purpose of offering shares of the Company’s common stock in an initial public offering (the “Offering”);

WHEREAS, in connection with the Offering, the Maker and the Payee agree that it is in their mutual best interest to reduce the interest rate applicable to the principal balance of the Existing Note from twenty percent (20%) to ten percent (10%) as of and following completion of the Offering; and

It is hereby agreed that the amended interest rate of ten percent (10%) will apply to the outstanding principal balance of the Existing Note from the Effective Date through the Maturity Date.
