[2] The Fund's administrator has entered into a Fund Accounting and Administration Agreement with the Fund that runs through January 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 January 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 $80 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 taxes, interest, brokerage fees and commissions, expenses on short sales, acquired fund fees and expenses, and extraordinary expenses. 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. The Advisor cannot recoup from the Fund any amounts paid under the Operating Plan.

The operating expenses in this fee table will not correlate to the expense ratio in the Fund's financial statements, once available, because the financial statements include only the direct operating expenses incurred by the Fund.
