This Amendment No. 4 amends Items 3 and 5 as set forth below.

Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

            Funds for the purchase of the Common Shares were derived from the subscription proceeds from investors in the Saba Entities and the capital appreciation thereon and margin account borrowings made in the ordinary course of business. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the account, which may exist from time to time.

A total of $10,752,171 was paid to acquire the Common Shares reported herein.
