 interests or the interests of its clients may conflict with the interests
of a Fund or Portfolio, as applicable (collectively, for purposes of this section, “Fund” or “Funds”). These activities
could cause Morgan Stanley to have an interest that is different from, and potentially adverse to, that of the Fund, which may impede
the Fund from participating in certain opportunities. Morgan Stanley advises clients and sponsors, manages or advises other investment
funds and investment programs, accounts and businesses (collectively, together with any new or successor funds, programs, accounts or
businesses sponsored, managed, or advised by the investment adviser or one of its investment adviser affiliates, the “Affiliated
Investment Accounts”) with a wide variety of investment objectives that in some instances may overlap or conflict with the Fund’s
investment objectives and present conflicts of interest. In addition, Morgan Stanley, the investment adviser and/or the investment adviser’s
investment adviser affiliates may also from time to time create new or successor Affiliated Investment Accounts that may compete with
the Fund and present similar conflicts of interest. The discussion below enumerates certain actual, apparent and potential conflicts of
interest. There is no assurance that conflicts of interest will be resolved in favor of Fund shareholders and, in fact, they may not be.

The conflicts summarized herein do not purport to be a complete
list or explanation of the conflicts associated with the financial or other interests the investment adviser or its affiliates may have
now or in the future. For more information about conflicts of interest, see the section entitled “Potential Conflicts of Interest”
in the SAI. Conflicts of interest not described below or in the SAI may also exist. References to the investment adviser in this section
include the Fund’s affiliated sub-adviser (if any) unless otherwise noted.

Material Nonpublic and Other Information.It is expected
that confidential or material nonpublic information regarding an investment or potential investment opportunity may become available to
the investment adviser. If such information becomes available, the investment adviser may be precluded (including by applicable law or
internal policies or procedures) from pursuing an investment or disposition opportunity with respect to such investment or disposition
opportunity, including for an extended period of time. This inability to buy or sell an investment could have an adverse effect on the
Fund’s portfolio due to, among other things, changes in an investment’s value during the period its trading is restricted.
Morgan Stanley has established certain information barriers and other policies designed to address the sharing of information
