<div align='center'>ABOUT THIS PROSPECTUS SUPPLEMENT</div>

This document has two parts. The first part is this
Prospectus Supplement, which describes the terms of the offering of the Common Shares. The second part is the accompanying Prospectus,
which contains more general information about the securities that the Fund may offer from time to time, some of which may not apply to
this offering of Common Shares. If information in this Prospectus Supplement is inconsistent with the accompanying Prospectus, you should
rely on this Prospectus Supplement. You should carefully read this Prospectus Supplement and the accompanying Prospectus, together with
the additional information described under the heading “Where You Can Find More Information.”

This Prospectus Supplement and the accompanying Prospectus
and the SAI, contain (or will contain) or incorporate (or will incorporate) by reference forward-looking statements, within the meaning
of the federal securities laws, that involve risks and uncertainties. These statements describe the Fund’s plans, strategies, and
goals and the Fund’s beliefs and assumptions concerning future economic and other conditions and the outlook for the Fund, based
on currently available information. In this Prospectus Supplement and the accompanying Prospectus, words such as “anticipates,”
“believes,” “expects,” “objectives,” “goals,” “future,” “intends,”
“seeks,” “will,” “may,” “could,” “should,” and similar expressions, and the
negative of such terms, are used in an effort to identify forward-looking statements, although some forward-looking statements may be
expressed differently. By their nature, all forward looking statements involve risks and uncertainties, and actual results could differ
materially from those contemplated by any forward looking statements. Although the Fund believes that the expectations expressed in these
forward looking statements are reasonable, actual
