Conflicts of Interest

In addition to managing the assets of the Fund,  the Fund's  portfolio  managers
may have responsibility for managing other client accounts of the Advisor or its
affiliates.  The tables below show, for each portfolio  manager,  the number and
asset size of (1) SEC registered  investment companies (or series thereof) other
than the Fund, (2) pooled investment vehicles that are not registered investment
companies and (3) other  accounts  (e.g.,  accounts  managed for  individuals or
organizations)  managed by the portfolio manager. Total assets attributed to the
portfolio  managers in the tables  below  include  total  assets of each account
managed  by them,  although  the  managers  may only  manage a  portion  of such
account's  assets.  The  tables  also show the number of  performance  based fee
accounts, as well as the total assets of the accounts for which the advisory fee
is based on the  performance of the account.  The information for Robert Wang is
provided as of August 31, 2009.
