In early November you should have received proxy materials seeking your vote for the Special Meeting of Shareholders. So far, we have received voting instructions from many shareholders, but as of the date of this letter our records indicate that we have not yet received a vote on behalf of your shares. We ask that you PLEASE HELP US BY TAKING A MOMENT NOW TO VOTE. Please note that important matters are being voted on that will affect your investment in the Fund. It is important that we receive enough votes to complete the business of this meeting without additional delay and cost. WHY DOES IT MATTER IF I VOTE? As indicated in the Proxy Statement, one of the proposals presented requires the affirmative vote of a majority of the outstanding accounts in the Fund. This means that every shareholder's vote counts regardless of the number of shares owned. As a shareholder of record of the Energy Income and Growth Fund, your participation is critical to the outcome of this Meeting. If sufficient voting participation is not received by JANUARY 8TH additional expenses of further solicitation efforts could be incurred. Please help us to achieve sufficient voting participation by taking a moment to vote your shares today.
