The Sponsor has full power and authority, in its sole discretion, without seeking the approval of the Trustee or the Shareholders (a) to establish and designate and to change in any manner and to fix such preferences, voting powers, rights, duties and privileges of the Trust as the Sponsor may from time to time determine, (b) to divide the beneficial interest in the Trust into an unlimited amount of shares, with or without par value, as the Sponsor will determine, (c) to issue shares without limitation as to number (including fractional shares), to such persons and for such amount of consideration, subject to any restriction set forth in the Trust Agreement, if any, at such time or times and on such terms as the Sponsor may deem appropriate, (d) to divide or combine the shares into a greater or lesser number without thereby materially changing the proportionate beneficial interest of the shares in the assets held, and (e) to take such other action with respect to the shares as the Sponsor may deem desirable. The ownership of Shares is recorded on the books of the Trust or a transfer or similar agent for the Trust. No certificates certifying the ownership of Shares will be issued except as the Sponsor may otherwise determine from time to time. The Sponsor may make such rules as it considers appropriate for the issuance of share certificates, transfer of Shares and similar matters. The record books of the Trust as kept by the Trust, or any transfer or similar agent, as the case may be, are conclusive as to the identity of the Shareholders and as to the number of Shares held from time to time by each.

Shareholders who are not DTC Participants may transfer their Shares through DTC by instructing the DTC Participant holding their Shares (or by instructing the Indirect Participant or other entity through which their Shares are held) to transfer the Shares.
