This

Person”). Karpus is a registered investment adviser under Section 203 of the Investment Advisers Act of 1940. Karpus is controlled
by City of London Investment Group plc (“CLIG”), which is listed on the London Stock Exchange. However, in accordance

such that voting and investment power over the subject securities is exercised by Karpus independently of CLIG, and, accordingly,
attribution of beneficial ownership is not required between Karpus and CLIG.
