The Fund's Shares are offered for sale through the Distributor at NAV plus any applicable sales load.

The Distributor is not required to sell any specific number or dollar amount of the Fund's Shares but will use its best efforts to solicit orders for the sale of the Shares. Shares of the Fund will not be listed on any national securities exchange and the Distributor will not act as a market maker in Fund Shares.

The Adviser or its affiliates, in the Adviser's discretion and from its own resources, may pay additional compensation to financial intermediaries, brokers and their agents that have made arrangements with the Fund and are authorized to buy and sell Shares of the Fund (collectively, "Financial Intermediaries") in connection with the sale of Fund Shares (the "Additional Compensation"). In return for the Additional Compensation, the Fund may receive certain marketing advantages including access to a broker's or dealer's registered representatives, placement on a list of investment options offered by a broker or dealer, or the ability to assist in training and educating the broker's or dealer's registered representatives. The Additional Compensation may differ among brokers or dealers in amount or in the amount of calculation. Payments of Additional Compensation may be fixed dollar amounts or, based on the aggregate value of outstanding Shares held by Shareholders introduced by the broker or dealer, or determined in some other manner.
