5:00 p.m., New York City time, on the Expiration Date (May 16, 2025), unless extended by the Fund (the “Extended
Expiration Date”). Rights will expire on the Expiration Date or Extended Expiration Date, as the case may be, and thereafter may
not be exercised.

Method of Exercising Rights. Rights
may be exercised by filling in and signing the reverse side of 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 for the Shares
as described below under “Payment for Shares.” Rights may also be exercised through a Rights holder’s broker, who may
charge the Rights holder a servicing fee in connection with such exercise.

In the event that the Estimated Subscription Price
is more than the Subscription Price on the Expiration Date (or Extended Expiration Date, as the case may be), any resulting excess amount
paid by a Stockholder towards the purchase of Shares in the Offering will be applied by the Fund towards the purchase of additional Shares
under the Basic Subscription or, if such Stockholder has exercised all of the Rights initially issued to such Stockholder under the Basic
Subscription, towards the purchase of an additional number of Shares pursuant to the Additional Subscription Privilege. Any Stockholder
who desires that such excess not be treated by the Fund as a request by the Stockholder to acquire additional Shares in the Offering
and that such excess be refunded to the Stockholder must so indicate in the space provided on the Subscription Certificate.

Completed Subscription Certificates must be received
by the Subscription Agent prior to 5:00 p.m., New York City time, on the Expiration Date (or Extended Expiration Date, as the case may
be). The Subscription Certificate and payment should be delivered to the Subscription Agent at the following address:
