[5] Osterweis Capital Management, LLC (the “Adviser”) has contractually agreed to reduce its fees and/or pay Fund expenses (excluding any front-end or contingent deferred loads, taxes, interest expenses, brokerage commissions, acquired fund fees and expenses, expenses incurred in connection with any merger or reorganization, extraordinary expenses such as litigation, or any class-specific expenses such as Rule 12b-1 fees or shareholder servicing plan fees) in order to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the Fund to 1.10% of the Fund’s average net assets (the “Expense Cap”). The Expense Cap will remain in effect until at least June 30, 2027, except that the Agreement may be terminated at any time by the Board of Trustees upon 60 days’ written notice to the Adviser, or by the Adviser with consent of the Board. The Adviser is permitted, with Board approval, to be reimbursed for fee reductions and/or expense payments made in the prior three years from the date the fees were waived and/or expenses were paid. This reimbursement may be requested if the aggregate amount actually paid by the Fund toward operating expenses for such period (taking into account any reimbursement) does not exceed the lesser of the Expense Cap in place at the time of waiver or at the time of reimbursement.
