[1] Becker Capital Management, Inc., (the "Advisor") has contractually agreed to reduce its management fee and/or reimburse certain expenses (excluding brokerage fees and commissions; borrowing costs, such as (a) interest and (b) dividend expenses on securities sold short; taxes; any indirect expenses, such as Acquired Fund Fees and Expenses; and extraordinary litigation expenses) so that Total Annual Fund Operating Expenses After Fee Waiver/Expense Reimbursement do not exceed 0.78% for the Retail Class and 0.68% for the Institutional Class of each class' respective average daily net assets (the "Expense Caps"). The Expense Caps will remain in effect at least through February 28, 2016. The Agreement may be terminated at any time by the Board of Trustees upon 60 days' notice to the Advisor, or by the Advisor with consent of the Board. The Advisor is permitted, with Board approval, to be reimbursed for fee reductions and/or expense payments made in the prior three years. This reimbursement may be requested if the aggregate amount actually paid by the Fund toward operating expenses for the fiscal year (taking into account the reimbursement) does not exceed the Expense Caps.

[2] The Total Annual Operating Expenses After Fee Waiver/Expense Reimbursement do not correlate to the Ratio of Expenses to Average Net Assets After Fees Waived/Recouped and Expenses Absorbed provided in the Financial Highlights Section of the statutory Prospectus, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.
