CREATION AND REDEMPTION OF CREATION UNITS	NOTE 6 – CREATION AND REDEMPTION OF CREATION UNITS The Funds issue and redeem Shares on a continuous basis at NAV in one or more large blocks of 50,000 Shares called Baskets. Each Fund intends to create and redeem Baskets primarily through exchange for related position ("EFRP") transactions.

The manner by which redemptions are made is dictated by the terms of the respective authorized participant agreement between an Authorized Participant and the Trust ("Authorized Participant Agreement"). Except when aggregated in Baskets, Shares are not redeemable securities of a Fund. Shares of the Funds may be purchased or redeemed only by Authorized Participants. An Authorized Participant is an institution that (i) is a broker-dealer; (ii) is a registered futures commission merchant and/or clears through a registered futures commission merchant; (iii) is a Depository Trust Company Participant and a member of the National Securities Clearing Corporation; (iv) has entered into an Authorized Participant agreement with the Trust; and (v) is in a position to transfer the required Deposit Instruments and/or the cash to buy and sell whole Baskets. Investors will purchase Shares in the secondary market, generally with the assistance of a broker or investment advisor and will be subject to customary brokerage commissions, mark ups and mark downs and fees. Authorized Participants will pay a transaction fee per Basket created or redeemed. The Sponsor may choose to pay transaction fees on behalf of Authorized Participants and has done so to date on Baskets that have been created. There is no guarantee that the Sponsor will continue to do so. In addition, to the extent that cash is delivered or received in lieu of any of the Deposit Instruments upon the creation or redemption of Shares by an Authorized Participant, such Authorized Participants will pay an additional variable charge up to 2% of the cash that is delivered or received in lieu of any of the Deposit Instruments to a Fund to pay for any additional transaction costs and fees and price changes associated with the purchase or disposition of any of the Deposit Instruments.
