aries and their financial advisors and
other salespersons with an incentive to favor sales of shares of the Fund over other investment options with respect to which these Financial
Intermediaries do not receive additional compensation (or receives lower levels of additional compensation). These payment arrangements,
however, will not change the price that an investor pays for shares of the Fund or the amount that the Fund receives to invest on behalf
of an investor. Investors may wish to take such payment arrangements into account when considering and evaluating any recommendations
relating to Fund shares and should review carefully any disclosures provided by Financial Intermediaries as to their compensation.

The additional compensation received by a given Financial
Intermediary from the Adviser and/or the Distributor may vary from the additional compensation received by the Financial Intermediary
in respect of an Affiliated Investment Account managed by an affiliate of the Adviser or principally underwritten by an affiliate of the
Distributor. In such circumstances, differences in the prospect of receiving, or the receipt of, additional compensation, as described
above, by Financial Intermediaries may provide such Financial Intermediaries and their financial advisors and other salespersons with
an incentive to favor sales of shares of one Affiliated Investment Account over other investment options with respect to which these Financial
Intermediaries do not receive additional compensation (or receives lower levels of additional compensation).

and analysis, and render investment advice without regard for a Fund’s holdings, although these activities could have an adverse
impact on the value of one or more of the Fund’s investments, or could cause Morgan Stanley to have an interest in one or more portfolio
investments that is different from and potentially adverse to that of a Fund. Furthermore, from time to time, the Adviser or its affiliates
may invest “seed” capital in a Fund, typically to enable the Fund to commence investment operations and/or achieve sufficient
scale, as further described below. The Adviser and its affiliates may hedge such seed capital exposure by investing in derivatives or
other instruments expected to produce offsetting exposure. Such hedging transactions, if any, would occur outside of a Fund.

Morgan Stanley’s sales and trading, financing
and principal investing businesses (whether or not specifically identified as such, and including Morgan Stanley’s trading and principal
investing businesses) will not be required to offer any investment opportunities to a Fund. These businesses may encompass
