This Policy does not apply to MSIM’s authority
to exercise certain decision-making rights associated with investments in loans and other fixed-income instruments (collectively, “Fixed
Income Instruments”). Instead, MSIM’s Policy for Exercising Consents Related to Fixed Income Instruments applies to MSIM’s
exercise of discretionary authority or other investment management services, to the extent MSIM has been granted authority to exercise
consents for an account with respect to any Fixed Income Instruments held therein.

Proxy Voting Procedures

MSIM follows the following procedures when voting proxies:

A. Proprietary Proxy Voting Platform

MSIM uses a proprietary management system, Provosys3,
when voting proxies. Provosys streamlines our proxy voting process by providing a centralized platform for research, vote instruction
and management of conflicts of interests. We believe that the internal management of this process provides us with enhanced quality control,
as well as oversight and independence of the proxy administration process. Our proprietary system also handles workflow around proxy voting,
documenting the views of various investment teams and the GST where relevant.

B. Proxy Services Provided by Third Parties

MSIM also retains the services of Institutional Shareholder Services
(“ISS”) and Glass Lewis (collectively, the “Proxy Service Providers4”)
for proxy vote execution, reporting, record-keeping, and where appropriate, to provide company-level reports that summarize key data elements
within an issuer’s proxy statement or on specific thematic/market topics.

MSIM performs periodic due diligence on the Proxy Service Providers
as part of ongoing oversight. Topics of the reviews include, but are not limited to, the Proxy Service Providers’ management of
conflicts of interest, methodologies for developing their policies and vote recommendations, and resources.

C. Proxy Voting Operations

The GST5
is responsible for ensuring that voting instructions from investment teams and clients (where applicable) are communicated to our Proxy
Service Provider responsible for proxy vote execution (currently, ISS serves in this capacity) and that adequate controls are in place
to ensure instructions communicated electronically are accurately recorded in ISS systems for execution (including scenarios where votes
have been split because of client preference or differing investment team convictions).

Additionally, the GST conducts monthly reviews of a vote
