Now, Therefore, in consideration of the foregoing facts and other good and valuable consideration, the parties hereto hereby agree as follows:

Section 1. Definitions. The following terms shall have the following definitions in this Agreement:

“Expense Ratio” is defined as a Fund’s annual investment management fees and acquired fund fees and expenses (but excludes interest charges on any borrowings (including net interest expenses incurred in connection with an investment in reverse repurchase agreements or futures contracts), dividends and other expenses on securities sold short, taxes (of any kind or nature, including, but not limited to, income, excise, transfer and withholding taxes), brokerage commissions and other expenses incurred in placing orders for the purchase and sale of securities and other investment instruments (including any net account or similar fees charged by futures commission merchants) or in connection with creation and redemption transactions (including without limitation any fees, charges, taxes, levies or expenses related to the purchase or sale of an amount of any currency, or the patriation or repatriation of any security or other asset, related to the execution of portfolio transactions or any creation or redemption transactions), accrued deferred tax liability, fees and expenses payable related to the provision of securities lending services, legal fees or expenses in connection with any arbitration, litigation or pending or threatened arbitration or litigation, including any settlements in connection therewith, extraordinary expenses, and distribution fees and expenses paid by the Trust under any distribution plan adopted pursuant to Rule 12b-1 under the 1940 Act) as a percentage of such Fund’s daily net asset value.
