EXPLANATORY NOTE

This Post-Effective Amendment No. 1 to the Registration Statement of Midas Series Trust ("Registrant") on Form N-14 hereby incorporates by reference Parts A and B of Registrant's Registration Statement on Form N-14 (File No. 333-209306) filed with the Securities and Exchange Commission on May 3, 2016 as Pre-Effective Amendment No. 3 thereto. The purpose of this Post-Effective Amendment No. 1 is to file as Exhibit 1 hereto the Amended Trust Instrument and as Exhibit 12 hereto the Opinion of Counsel on Tax Matters of Godfrey & Kahn, S.C.

PART C. OTHER INFORMATION

Item 15. Indemnification

Reference is made to the provisions of Article IX of Midas Series Trust's (the "Registrant") Amended Trust Instrument filed herewith as Exhibit 1, incorporated herein by reference, which provides information about indemnification.

The Registrant's Investment Management Agreement between the Registrant and Midas Management Corporation (the "Investment Manager") provides that the Investment Manager shall not be liable to the Registrant's series or any shareholder of its series for any error of judgment or mistake of law or for any loss suffered by the Registrant's series or the series' shareholders in connection with the matters to which the Investment Management Agreement relates. However, the Investment Manager is not protected against any liability to the Registrant's series or any shareholder of its series by reason of willful misfeasance, bad faith, or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under the Investment Management Agreement.

Section 10 of the Distribution Agreement between the Registrant and Midas Securities Group, Inc. (the "Distributor") provides that the Registrant will indemnify the Distributor and its officers, directors and controlling persons against all liabilities arising from any alleged untrue statement of material fact in the Registrant's registration statement on Form N-14 ("Registration Statement") or from any alleged omission to state in the Registration Statement a material fact required to be stated in it or necessary to make the statements in it, in light of the circumstances under which they were made, not misleading, except insofar as liability arises from untrue statements or omissions made in reliance upon and in conformity with information furnished by the Distributor to the Registrant for use in the Registration Statement; and provided that this indemnity agreement shall not protect any such persons against liabilities arising by reason of their bad faith, gross negligence or willful misfeasance; and shall not inure to the benefit of any such persons unless a court of competent jurisdiction or controlling precedent determines that such result is not against public policy as expressed in the Securities Act of 1933, as amended (the "Securities Act"). Section 10 of the Distribution Agreement also provides that the Distributor agrees to indemnify, defend and hold the Registrant, its officers and directors free and harmless of any claims arising out of any alleged untrue statement or any alleged omission of material fact contained in information furnished by the Distributor for use in the Registration Statement or arising out of any agreement between the Distributor and any retail dealer, or arising out of supplementary literature or advertising used by the Distributor in connection with the Distribution Agreement.

The Registrant undertakes to carry out all indemnification provisions of its Amended Trust Instrument, the above-described Investment Management Agreement and Distribution Agreement in accordance with Investment Company Act Release No. 11330 (September 4, 1980) and successor releases.

Insofar as indemnification for liability arising under the Securities Act may be provided to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Investment Company Act of 1940, as amended (the "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, officer or 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, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
