[1] The Fund's administrator has entered into a Fund Accounting and Administration Agreement with the Fund that runs through July 31, 2014. The agreement can only be terminated prior to that date at the discretion of the Fund's Board of Trustees. The Fund's administrator receives payments under the agreement at a maximum annual rate of 0.30%. In conjunction with the Fund Accounting and Administration Agreement, the Advisor has entered into an Operating Plan with the Fund's administrator, also through July 31, 2014, under which it has agreed (i) to pay the administrator a fee based on the daily average net assets of the Fund when net assets are below $90 million; (ii) if these payments are less than a designated minimum, then the Advisor pays a fee that makes up the difference; and (iii) to assume expenses of the Fund outlined in the Operating Plan that are not covered by the fee paid under Fund Accounting and Administration Agreement. These measures are intended to limit the Fund's operating expenses to 1.50% of the average daily net assets, exclusive of brokerage fees and commissions, taxes, borrowing costs (such as interest or dividend expenses on securities sold short), acquired fund fees and expenses, extraordinary expenses, and distribution and/or service (12b-1) fees. The Fund's net expense ratio will be higher than 1.50% to the extent the Fund incurs expenses excluded from this arrangement. The Operating Plan can only be terminated prior to the conclusion of the current term with the approval of the Fund's Board of Trustees.
