Item 29.

Persons Controlled By or Under Common Control with Registrant

Not Applicable.

Item 30.

Indemnification

Pursuant to Article VII, Section 2(a) of the Trust's Agreement and Declaration of Trust (the "Declaration"), the Trust shall indemnify, out of Trust Property (as such term is defined in the "Declaration"), to the fullest extent permitted under applicable law, any Person (as such term is defined in the "Declaration") who was or is a party or is threatened to be made a party to any Proceeding (as such term is defined in the "Declaration") by reason of the fact that such Person is or was an Agent (as such term is defined in the "Declaration") of the Trust, against Expenses (as such term is defined in the "Declaration"), judgments, fines, settlements and other amounts actually

and reasonably incurred in connection with such Proceeding if such Person acted in good faith or in the case of a criminal proceeding, had no reasonable cause to believe the conduct of such Person was unlawful. The termination of any Proceeding by judgment, order, settlement, conviction or plea of nolo contendere or its equivalent shall not of itself create a presumption that the Person did not act in good faith or that the Person had reasonable cause to believe that the Person's conduct was unlawful.

Insofar as indemnification for liability arising under the Securities Act of 1933 (the "1933 Act") may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions of Rule 484 under the 1933 Act, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the 1933 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 1933 Act and will be governed by the final adjudication of such issue.

The Registrant hereby undertakes that it will apply the indemnification provision of the Declaration in a manner consistent with Release 11330 of the SEC under the 1940 Act, so long as the interpretation of Sections 17(h) and 17(i) thereunder remains in effect.

Item 31.

Business and Other Connections of the Investment Adviser

Certain information pertaining to the business and other connections of Roundhill Financial Inc. ("Roundhill"), the investment adviser to the Funds, is hereby incorporated by reference from the Prospectuses and Statements of Additional Information contained herein. The information required by this Item with respect to any director, officer or partner of Roundhill is incorporated by reference to the Form ADV filed by Roundhill with the Securities and Exchange Commission pursuant to the Investment Advisers Act of 1940, as amended (File No. 801-114971).

Certain information pertaining to the business and other connections of Exchange Traded Concepts, LLC ("ETC"), the investment sub-adviser to the Funds, is hereby incorporated by reference from the Prospectuses and Statements of Additional Information contained herein. The information required by this Item with respect to any director, officer or partner of ETC is incorporated by reference to the Form ADV filed by ETC with the Securities and Exchange Commission pursuant to the Investment Advisers Act of 1940, as amended (File No. 801-70485).
