PART II
INFORMATION NOT REQUIRED IN PROSPECTUS

Item 13.    Other Expenses of Issuance and Distribution

    The following table sets forth the costs and expenses, other than underwriting discounts and commissions, payable in connection with the sale and distribution of the securities being registered. All amounts are estimated except the SEC registration fee and the FINRA filing fee. Except as otherwise noted, all the expenses below will be paid by Erickson Air-Crane Incorporated.

Item 14.    Indemnification of Directors and Officers

    Section 145 of the Delaware General Corporation Law (the "DGCL"), authorizes a court to award, or a corporation's board of directors to grant, indemnity to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities, including reimbursement for expenses incurred or, arising under the Securities Act of 1933, as amended. Our second amended and restated certificate of incorporation provides for indemnification of our directors, officers, employees, and other agents to the maximum extent permitted by the DGCL, and our second amended and restated bylaws provide for indemnification of our directors, officers, employees, and other agents to the maximum extent permitted by the DGCL. In addition, we have entered into indemnification agreements with our directors, officers, and some employees containing provisions which are in some respects broader than the specific indemnification provisions contained in the DGCL. The indemnification agreements may require us, among other things, to indemnify our directors against certain liabilities that may arise by reason of their status or service as directors and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified. Reference is also made to Section 7 of the underwriting agreement to be filed as Exhibit 1.1 hereto, which provides for indemnification by the underwriter of our officers and directors against certain liabilities.

Item 15.    Recent Sales of Unregistered Securities

    None.

Item 17.    Undertakings

    The undersigned registrant hereby undertakes to provide to the underwriter at the closing specified in the underwriting agreements certificates in such denominations and registered in such names as required by the underwriter to permit prompt delivery to each purchaser.

    Insofar as indemnification for liabilities arising under the Securities Act may be permitted as to directors, officers, and controlling persons of the registrant pursuant to the provisions described in Item 14, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for

indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, an officer or a controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, we will, unless in the opinion of our counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by us is against public policy as expressed in the Securities Act, and we will be governed by the final adjudication of such issue.

    The undersigned registrant hereby undertakes that:

    (1)  For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus as filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

    (2)  For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
