 potentially adverse to, that of the Fund, which may impede the Fund
from participating in certain opportunities. In instances where trading of an investment is restricted, the Adviser may not be able to
purchase or sell such investment on behalf of a Fund including for an extended period of time, resulting in a Fund’s inability to
participate in certain desirable transactions. This inability to buy or sell an investment could have an adverse effect on a 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 between different businesses within Morgan Stanley. As a result
of information barriers, the Adviser, in certain instances, will not have access, or will have limited access, to certain information
and personnel in other areas of Morgan Stanley and, in such instances, will not manage the Funds with the benefit of the information held
by such other areas. Morgan Stanley, due to its access to and knowledge of funds, markets and securities based on its various businesses,
may make decisions based on information or take (or refrain from taking) actions with respect to interests in investments of the kind
held (directly or indirectly) by the Funds in a manner that may be adverse to the Fund, and will not have any obligation or other duty
to share information with the Adviser.

In other instances, Morgan Stanley personnel, including
personnel of the Adviser, will have access to information and personnel of its affiliates. For example, the Adviser may, in certain instances,
share information with its affiliates regarding due diligence of companies and other investment-related due diligence. The Adviser may
face conflicts of interest in determining whether to engage in the sharing of information with its affiliates. Information sharing may
limit or restrict the ability of the Adviser to engage in or otherwise effect transactions on behalf of the Funds (including purchasing
or selling securities that the Adviser may otherwise have purchased or sold for a Fund in the absence of the sharing of information).
Also, it may adversely affect a Fund’s investments, ability to invest in, or divest from, a company or engage in transactions or
otherwise disadvantage a Fund. In managing conflicts of interest that arise because of the foregoing, the Adviser generally will be subject
to fiduciary requirements. The Adviser may also implement internal information barriers or ethical walls or other internal information
sharing protocols, and the conflicts described herein with respect
