Except for the fees charged by EQ Fund Solutions, LLC,
the information agent for the Offer (the “Information Agent”), the Subscription Agent and the Dealer Manager (which are expected
to be paid from the proceeds of the Offer by the Fund), all commissions, fees and other expenses (including brokerage commissions and
transfer taxes) incurred or charged in connection with the purchase, sale or transfer of Rights will be for the account of the transferor
of the Rights, and none of these commissions, fees or other expenses will be paid by the Fund, the Investment Adviser, the Information
Agent, the Subscription Agent or the Dealer Manager. Rights holders who wish to purchase, sell, exercise or transfer Rights through a
broker, bank or other party should first inquire about any fees and expenses that the holder will incur in connection with the transactions.

The Fund anticipates that the Rights will be eligible
for transfer through, and that the exercise of the primary subscription and the over-subscription may be effected through, the facilities
of DTC or the Subscription Agent until 5:00 p.m., Eastern time, on the Expiration Date. Your broker, bank, trust company or other
intermediary may impose a deadline for transferring Rights earlier than 5:00 p.m. Eastern time, on the Expiration Date.

Method for Exercising Rights

Rights are evidenced by subscription certificates that
will be mailed to Record Date Shareholders (except as described under “—Requirements for Foreign Shareholders” below)
or, if their Common Shares are held by Cede & Co. or any other depository or nominee on their behalf, to Cede & Co. or such other
depository or nominee. Rights may be exercised by completing and signing the subscription certificate and mailing it in the envelope provided,
or otherwise delivering the completed and signed subscription certificate to the Subscription Agent, together with payment in full at
the estimated Subscription Price for the Common Shares subscribed for by the Expiration Date as described under “—Payment
for Common Shares.” Rights may also be exercised through the broker of a holder of Rights, who may charge the holder of Rights a
servicing fee in connection with such exercise. Rights may also be exercised by contacting your broker, bank, trust company or other intermediary,
which can arrange, on your behalf, to guarantee delivery of a properly completed and executed subscription certificate pursuant to a notice
of guaranteed delivery by the close of business on the first business day after the Expiration Date. A
