 a service provider to vote such shares
in favor of the proposal. Depending on its policies, applicable law or contractual or other restrictions, a service agent may be permitted to vote shares with respect to which it has not received specific voting instructions from its customers. In
those cases, the service agent may, but may not be required to, vote such shares in the same proportion as those shares for which the service agent has received voting instructions. This practice is commonly referred to as “echo voting.”

All properly executed proxies received prior to the Special Meeting will be voted in accordance with the instructions marked thereon or
otherwise as provided therein. Unless instructions to the contrary are marked, proxies will be voted “FOR” the approval of each proposal. Abstentions and broker non-votes, if any, will not be
voted.

Common shareholders of MVT are being asked to consider Proposal 1(A) below. With respect to Proposal 1(A), abstentions and broker non-votes will be counted as shares present and will therefore have the same effect as votes “AGAINST” the proposal.

Common shareholders of MIY are being asked to consider Proposal 1(C) below. With respect to Proposal 1(C), abstentions and broker non-votes will be counted as shares present and will therefore have the same effect as votes “AGAINST” the proposal.

Common shareholders of MVF are being asked to consider Proposal 1(E) below. With respect to Proposal 1(E), abstentions and broker non-votes will be counted as shares present and will therefore have the same effect as votes “AGAINST” the proposal.

Common shareholders of the Acquiring Fund are being asked to consider Proposals 2(A) and 2(B) below. With respect to Proposals 2(A), 2(B) and
2(C), abstentions will be counted as “votes cast” and will therefore have the same effect as votes “AGAINST” the proposal and broker non-votes will not have any effect on the result of
the vote.
