Re: ENERGY INCOME AND GROWTH FUND SPECIAL MEETING OF SHAREHOLDERS

Dear Valued Shareholder:

Our records indicate that we have not yet received your important proxy vote for
the Special Meeting of Shareholders of Energy Income and Growth Fund, scheduled
to be held on January 8, 2008 at 4:00 p.m. Central Time. 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. If you need another copy of the Proxy Statement, have
any proxy-related questions, or wish to vote your proxy by phone, PLEASE CALL
1-800-761-6707 for assistance.
