| · | New common shares of MFM and MMT will be issued as part 
 of the proposed reorganization.                         |

Pending shareholder approval, the above proposal is expected to be completed
in June 2026, after which MFM and MMT will be rebranded with the Aberdeen name.

If the appointment of Aberdeen as investment adviser is not approved by
shareholders of MFM and MMT, MFS will continue to remain as the investment adviser for these funds and current MFS trustees will remain
trustees of the closed end funds.

The board of trustees of each MFS closed end fund believe that these proposals are in the best long-term interests of each MFS closed end Fund’s shareholders and therefore recommend a vote FOR the proposal.
