a Fund. There is a risk that such seed investors may redeem their investments in the Fund, particularly after payments from the Adviser
and/or its affiliates have ceased. Such redemptions could negatively impact a Fund’s liquidity, expenses and market price of its
shares, as applicable.

Allocation of Expenses.Expenses may be incurred
that are attributable to a Fund and one or more other Affiliated Investment Accounts (including in connection with issuers in which a
Fund and such other Affiliated Investment Accounts have overlapping investments). The allocation of such expenses among such entities
raises potential conflicts of interest. The Adviser and its affiliates intend to allocate such common expenses among a Fund and any such
other Affiliated Investment Accounts on a pro rata basis or in such other manner as the Adviser deems to be fair and equitable or in such
other manner as may be required by applicable law.

Temporary Investments.To more efficiently invest
short-term cash balances held by a Fund, the Adviser may invest such balances on an overnight “sweep” basis in shares of one
or more money market funds or other short-term vehicles. It is anticipated that the investment adviser to these money market funds or
other short-term vehicles may be the Adviser (or an affiliate) to the extent permitted by applicable law, including Rule 12d1-1 under
the 1940 Act. In such a case, the affiliated investment adviser may receive asset-based fees in respect of a Fund’s investment (which
will reduce the net return realized by a Fund).

Transactions with Affiliates.The investment
adviser and any investment sub-adviser might purchase securities from underwriters or placement agents in which a Morgan Stanley affiliate
is a member of a syndicate or selling group, as a result of which an affiliate might benefit from the purchase through receipt of a fee
or otherwise. Neither the investment adviser nor any investment sub-adviser will purchase securities on behalf of a Fund from an affiliate
that is acting as a manager of a syndicate or selling group. Purchases by the investment adviser on behalf of a Fund from an affiliate
acting as a placement agent must meet the requirements of applicable law. Furthermore, Morgan Stanley may face conflicts of interest when
the Funds use service providers affiliated with Morgan Stanley because Morgan Stanley receives greater overall fees when they are used.

Affiliated Indexes. Affiliates of the Adviser
develop, own and operate indexes (“Indexes”), and may continue to do so in the future, based on investment
