 ARTICLE I 

AMENDMENTS 
 SECTION 1.1
Amendments. The Trust Agreement is hereby amended as follows: 
 (a) Section 7.4 of the Trust Agreement is
hereby amended and restated in its entirety to read as follows: 
 Subject to any other requirements of applicable law including
Section 3816 of the Delaware Trust Statute, no Shareholder shall have the right, power or authority to bring or maintain a derivative action, suit or other proceeding on behalf of the Trust unless two or more Shareholders who (i) are not
Affiliates of one another and (ii) collectively hold at least 10% of the outstanding Shares join in the bringing or maintaining of such action, suit or other proceeding. This Section 7.4 shall not apply to any derivative claims brought
under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, or the rules and regulations thereunder.

ARTICLE II 

MISCELLANEOUS 
 SECTION
2.1 Governing Law. The validity and construction of this Amendment shall be governed by the laws of the State of Delaware, and the rights of all parties hereto and the effect of every provision hereof shall be subject to and construed
according to the laws of the State of Delaware without regard to the conflict of laws provisions thereof. 
 SECTION 2.2 Provisions In
Conflict With Law or Regulations. (a) The provisions of this Amendment are severable, and if the Sponsor shall determine, with the advice of counsel, that any one or more of such provisions (the “Conflicting Provisions”)
are in conflict with the Code, the Delaware Trust Statute, the Securities Act, if applicable, or other applicable U.S. federal or state laws or the rules and regulations of any Secondary Market, the Conflicting Provisions shall be deemed never to
have constituted a part of this Amendment, even without any amendment of this Amendment pursuant to this Amendment; provided, however, that such determination by the Sponsor shall not affect or impair any of the remaining provisions of
this Amendment or the Trust Agreement, or render invalid or improper any action taken or omitted prior to such determination. No Sponsor or Trustee shall be liable for making or failing to make such a determination. 

(b) If any provision of this Amendment shall be held invalid or unenforceable in any jurisdiction, such holding shall not in any manner affect
or render invalid or unenforceable such provision in any other jurisdiction or any other provision of this Amendment in any jurisdiction. 

SECTION 2.3 Construction. In this Amendment, unless the context otherwise requires, words used in the singular or in the plural include
both the plural and singular and words denoting any gender include all genders. The title and headings of different parts are inserted for convenience and shall not affect the meaning, construction or effect of this Amendment. 

SECTION 2.4 Counterparts; Electronic Signatures. This Amendment may be executed in one or more counterparts (including those by
facsimile or other electronic means), all of which shall constitute one and the same instrument binding on all of the parties hereto, notwithstanding that all parties are not signatory to the original or the same counterpart. This Amendment, to the
extent signed and delivered by means of a facsimile machine or other electronic transmission, shall be treated in all manner and respects as an original agreement and shall be considered to have the same binding legal effect as if it were the
original signed version thereof delivered in person. 
 SECTION 2.5 Defined Terms. For purposes of this Amendment, any capitalized
terms used and not defined herein shall have the same respective meanings as assigned to them in the Trust Agreement.
