exercises its Basic Subscription Privilege in full may subscribe for a number of Excess Shares pursuant to the terms and conditions of the Rights Offering, as described in the Prospectus (the “Additional Subscription Privilege”). In addition, the Fund may issue additional shares up to 10% of the shares available in the Rights Offering to honor Additional Subscription Privilege requests. The Rights represented by this Subscription Rights Certificate may be exercised by completing Form 1 and any other appropriate forms on the reverse side hereof and by retuning the full payment of the subscription price for each share of beneficial interest.
