 the Meeting

a Fund without further notice to permit further solicitation of proxies.

By returning the enclosed form of proxy,
you are authorizing the persons named on the proxy to vote in their discretion on any other matter that properly comes before the
Meetings.

Broker-dealer firms holding shares in “street
name” for the benefit of their customers and clients are generally required to request the instruction of such customers
and clients on how to vote their shares on the proposals. A broker-dealer firm that is subject to the rules of the NYSE and that
has not received instructions from a customer prior to the date specified in its request for voting instructions may not vote such
customer’s shares on Proposal No. 1 or Proposal No. 2 described in this Joint Proxy Statement/Prospectus but may vote
such customer’s shares on Proposal No. 3 in such broker-dealer’s discretion. A signed proxy card or other authorization
by a beneficial owner of shares of a Fund that does not specify how the beneficial owner’s shares are to be voted on a proposal
may be deemed to be an instruction to vote such shares in favor of the proposal.

IF YOU CANNOT BE PRESENT AT THE MEETINGS, YOU ARE REQUESTED TO FILL IN, SIGN AND RETURN THE ENCLOSED PROXY PROMPTLY. NO POSTAGE IS REQUIRED IF MAILED IN THE UNITED STATES.
