 to information barriers and otherwise with respect to Morgan Stanley
and the Adviser will also apply internally within the Adviser. As a result, a Fund may not be permitted to transact in (e.g., dispose
of a security in whole or in part) during periods when it otherwise would have been desirable and able to do so, which could adversely
affect a Fund. Other investors in the security that are not subject to such restrictions may be able to transact in the security during
such periods. There may also be circumstances in which, as a result of information held by certain portfolio management teams in the Adviser,
the Adviser limits an activity or transaction for a Fund, including if
a Fund is managed by a portfolio management team other than the team holding such information.

thereof. Additionally, different portfolio management teams within the Adviser may make decisions based on information or take (or refrain
from taking) actions with respect to Affiliated Investment Accounts they advise in a manner different than or adverse to the Funds.

managed by both the Adviser and one or more of the Adviser’s investment adviser affiliates. A Fund’s investment objectives
may overlap with the investment objectives of certain Affiliated Investment Accounts. As a result, the members of an investment team may
face conflicts in the allocation of investment opportunities among a Fund and other investment funds, programs, accounts and businesses
advised by or affiliated with the Adviser or its investment adviser affiliates. Certain Affiliated Investment Accounts may provide for
higher management or incentive fees or greater expense reimbursements or overhead allocations, all of which may contribute to this conflict
of interest and create an incentive for the Adviser to favor such
