to the investment sub-advisory agreement among Olive Street Investment Advisers, LLC, Massachusetts Financial Services Company (d/b/a MFS Investment Management) ("MFS") and the Trust, pursuant to
which MFS is expected to begin serving as a sub-adviser to an allocated portion of the Fund ("MFS's Allocated Portion of the Fund") on or around September 30, 2025 (the "Effective
