Material Non-Public and Other Information.It
is expected that confidential or material non-public information regarding an investment or potential investment opportunity may become
available to the Adviser. If such information becomes available, the 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. The Adviser may also from time to time be subject to contractual “stand-still” obligations
and/or confidentiality obligations that may restrict its ability to transact in certain investments on a Fund’s behalf. In addition,
the Adviser may be precluded from disclosing such information to an investment team, even in circumstances in which the information would

Furthermore, access to information held by certain parts of Morgan Stanley may be subject to third party confidentiality obligations and
to information barriers established by Morgan Stanley designed to manage potential conflicts of interest and regulatory restrictions,
including, without limitation, joint transaction restrictions pursuant to the 1940 Act. Accordingly, the Adviser’s ability to source
investments from, or invest alongside, other business units within Morgan Stanley may be limited and there can be no assurance that the
Adviser will be able to source any investments from any one or more parts of the Morgan Stanley network.

The Adviser may restrict its investment decisions and
activities on behalf of the Funds in various circumstances, including because of applicable regulatory requirements or information held
by the Adviser, the Adviser’s investment adviser affiliates or Morgan Stanley. The Adviser might not engage in transactions or other
activities for, or enforce certain rights in favor of, a Fund due to Morgan Stanley’s activities outside the Funds. Furthermore,
Morgan Stanley could have an interest that is different from, and
