The Distributor shall act in good faith and in a commercially reasonable manner to mitigate any Losses it may suffer to the extent possible.

The Trust does not agree to indemnify the Distributor or hold it harmless under Section 6(a)(iii) to the extent that such untrue statement of material fact or omission to state a material fact was made in good faith reliance upon, and in conformity with, written materials prepared by or on behalf of the Distributor regarding the Distributor and furnished to the Trust or its agents by or on behalf of the Distributor for inclusion in the Registration Statement, Prospectus, Statement of Additional Information, shareholder reports, Marketing Materials and/or advertisements.

(b)The Distributor agrees to indemnify and hold harmless the Trust and each of its Trustees and officers and any person who controls the Trust within the meaning of Section 15 of the 1933 Act (for purposes of this paragraph, the Trust and each of its Trustees and officers and its controlling persons are collectively referred to as the “Trust Indemnitees”) against any Losses arising out of or based upon (i) the allegation of any wrongful act of the Distributor or any of its directors, officers, employees or affiliates in connection with its activities or obligations as the principal underwriter of the Funds pursuant to this Agreement; (ii) the breach of any obligation, representation or warranty contained in this Agreement by the Distributor; (iii) the Distributor’s failure to comply in any material respect with applicable securities laws, including applicable FINRA regulations; or (iv) any allegation that the Registration Statement, Prospectus, Statement of Additional Information, shareholder reports, any information or materials relating to the Funds (as described in section 3(g)) or other information filed or made public by the Trust (as from time to time amended) included an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make

7

the statements not misleading, insofar as such statement or omission was made in reliance upon, and in conformity with information furnished to, the Trust in writing by or on behalf of the Distributor. The Trust shall act in good faith and in a commercially reasonable manner to mitigate any Losses it may suffer to the extent possible.

(c)In no case (i) is the indemnification provided by an indemnifying party to be deemed to protect or indemnify against any liability the indemnified party would otherwise be subject by reason of willful misfeasance, bad faith, fraud, or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under this Agreement, or (ii) is the indemnifying party to be liable under its indemnity agreement contained in this Section with respect to any claim made against any indemnified party unless the indemnified party notifies the indemnifying party in writing of the claim within a reasonable time after the summons or other first written notification giving information of the nature of the claim shall have been served upon the indemnified party (or after the indemnified party shall have received notice of service on any designated agent).

(d)Failure to notify the indemnifying party of any claim shall not relieve the indemnifying party from any liability that it may have to the indemnified party against whom such action is brought, on account of this Section, unless failure or delay to so notify the indemnifying party prejudices the indemnifying party’s ability to defend against such claim. The indemnifying party shall be entitled to participate at its own expense in the defense or, if it so elects, to assume the defense of any suit brought to enforce the claim, but if the indemnifying party elects to assume the defense, the defense shall be conducted by counsel chosen by it and reasonably satisfactory to the indemnified party in the suit. In the event that indemnifying party elects to assume the defense of any suit and retain counsel, the indemnified party shall bear the fees and expenses of any additional counsel retained by them. If the indemnifying party does not elect to assume the defense of any suit, it will reimburse the indemnified party for the reasonable fees and expenses of any counsel retained by them. The indemnifying party agrees to notify the indemnified party promptly of the commencement of any litigation or proceedings against it or any of its officers or directors in connection with the purchase or redemption of any of the Creation Units or the Shares.

(e)No indemnified party shall settle any claim against it for which it intends to seek indemnification from the indemnifying party, under the terms of section 6(a) or 6(b) above, without prior written notice to and consent from the indemnifying party, which consent shall not be unreasonably withheld. No indemnified or indemnifying party shall settle any claim unless the settlement contains a full release of liability with respect to the other party in respect of such action. This section 6 shall survive the termination of this Agreement.

(f)Notwithstanding anything contained herein to the contrary, neither party shall be liable to the other party for any indirect, special or consequential damages (“Indirect Damages”); provided that the foregoing limitation shall not apply with respect to Indirect Damages arising out of or relating to that party’s fraud or willful misconduct.
