 DNP Select Income Fund Inc. (“DNP”), Duff & Phelps Utility and
Infrastructure Fund Inc. (“DPG”) and DTF Tax-Free Income 2028 Term Fund Inc. (“DTF” and, together with DNP and DPG, the “Funds” and each a “Fund”) is soliciting proxies
from the shareholders of each Fund for use at the joint annual meeting of shareholders to be held on Monday, March 10, 2025 and at any adjournment or postponement of that meeting. A proxy may be revoked at any time before it is voted, either by
voting at the meeting or by written notice to the applicable Fund or delivery of a later-dated proxy.

The meeting is scheduled as a joint
meeting of the respective shareholders of the Funds because the shareholders of each Fund are expected to consider and vote on similar matters. The Board has determined that the use of a joint proxy statement for the meeting is in the best interest
of the shareholders of each Fund. In the event that any shareholder of a Fund virtually present at the meeting objects to the holding of a joint meeting, raises a reasonable basis for the objection, and moves for an adjournment of such Fund’s
meeting to a time immediately after the meeting, so that such Fund’s meeting may be held separately, the persons named as proxies will vote in favor of such adjournment. Shareholders of each Fund will vote separately on each of the proposals
relating to their respective Fund, and an unfavorable vote on a proposal by the shareholders of one Fund will not affect the implementation by the other Fund of such proposal if the shareholders of such other Fund approve the proposal.
