 Sub-Adviser(s).
To the extent the Adviser to a Fund engages affiliated and/or unaffiliatedsub-advisers, the
Adviser generally expects to compensate the sub-adviser out of the advisory fee it receives from the Fund, which creates an incentive
for the Adviser to select sub-adviser(s) with lower fee rates or to select affiliated sub-adviser(s). In addition, a sub-adviser may have
interests and relationships that create actual or potential conflicts of interest related to their management of Fund assets allocated
to or managed by the sub-adviser. These conflicts may be similar to or different from the conflicts described herein related to Morgan
Stanley and its investment advisory affiliates. For additional information about potential conflicts of interest for each sub- adviser(s)
can be found in the relevant sub-adviser’s Form ADV. A copy of Part 1 and Part 2 of a sub-adviser’s Form ADV is available
on the SEC’s website (www.adviserinfo.sec.gov).

Electronic Communication Networks and Alternative Trading Systems.The Adviser’s affiliate(s) have ownership interests in and/or board seats on electronic communication networks
(“ECNs”) or other alternative trading systems (“ATSs”). In certain instances the Adviser’s affiliate(s)
could be deemed to control one or more of such ECNs or ATSs based on the level of such ownership interests and whether such affiliates
are represented on the board of such ECNs or ATSs. Consistent with its fiduciary obligation to seek best execution, the Adviser may, from
time to time, directly or indirectly, effect client trades through ECNs or other ATSs in which the Firm’s affiliates have or could
acquire an interest or board seat. These affiliates might receive an indirect economic
benefit based upon their ownership in the ECNs or other ATSs. The Adviser will, directly or indirectly, execute through an ECN or other
ATSs in which an affiliate has an interest only in situations where the Firm or the broker dealer through whom it is accessing the ECN
or ATS reasonably believes such transaction will be in the best interest of its clients and the requirements of applicable law have been
satisfied.

General Process for Potential Conflicts.All
of the transactions described above involve the potential for conflicts of interest between the Adviser, related persons of the Adviser
and/or their clients. The Advisers Act, the 1940 Act and ERISA impose certain requirements
