TABLE OF FEES AND EXPENSES

The following tables are intended to assist you in understanding the various costs and expenses directly or indirectly associated with investing in our common shares as a percentage of net assets attributable to common shares. Amounts are for the current fiscal year after giving effect to anticipated net proceeds of the offering, assuming that we incur the estimated offering expenses, including preferred share offering expenses.

Shareholder Transaction Expenses

Sales Load (as a percentage of offering price)	[    ]%
Offering Expenses Borne by the Fund (as a percentage of offering price)	[    ]%
Dividend Reinvestment and Cash Purchase Plan Fees
Sale Transactions	$    1.00(1)
	Percentage of Net Assets              Attributable to Common Shares
Annual Expenses
Management Fees	%(2)
Base Fee	%
Performance Fee	%
Interest Payment on Borrowed Funds	None(3)
Other Expenses	%(4)
Total Annual Expenses	%
Dividends on Preferred Shares	%
Total Annual Expenses and Dividends on Preferred Shares	%(2)

(1) Shareholders participating in the Fund’s Automatic Dividend Reinvestment Plan do not incur any additional fees. Shareholders participating in the Voluntary Cash Purchase Plan would pay their pro rata share of brokerage commissions for transactions to purchase shares and $1.00 per transaction plus their pro rata share of brokerage commissions per transaction to sell shares. See “Automatic Dividend Reinvestment and Voluntary Cash Purchase Plan.”

(2) The Investment Adviser’s fee is 1.00% annually of the Fund’s average weekly net assets, with no deduction for the liquidation preference of any outstanding preferred shares, as defined in the Fund’s investment advisory agreement. Consequently, if the Fund has preferred shares outstanding, the investment management fees and other expenses as a percentage of net assets attributable to common shares will be higher than if the Fund does not utilize a leveraged capital structure.

(3) The Fund has no current intention of borrowing from a lender.

(4) “Other Expenses” are based on estimated amounts for the current year assuming completion of the proposed issuances.

For a more complete description of the various costs and expenses a common shareholder would bear in connection with the issuance and ongoing maintenance of any preferred shares issued by the Fund, see “Risk Factors and Special Considerations—Leverage Risk.”

The following example illustrates the expenses you would pay on a $1,000 investment in common shares, followed by a preferred share offering, assuming a 5% annual portfolio total return.* The expenses illustrated in the following example include the maximum estimated sales load on common shares of $10 and on preferred shares of $31.50, and estimated offering expenses of $[    ] from the issuance of $[    ] million in common shares and $[    ] million in preferred shares. The preferred shares sales load is spread over the Fund’s entire net assets attributable to common shares (assuming completion of the proposed issuances); therefore, the allocable portion of such sales load to a

common shareholder making a $1,000 investment in these circumstances is estimated to be $[    ]. The actual amounts in connection with any offering will be set forth in the Prospectus Supplement if applicable.

	1 Year	3 Years	5 Years	10 Years
Total Expenses Incurred

* The example should not be considered a representation of future expenses. The example is based on total Annual Expenses and Dividends on Preferred Shares shown in the table above and assumes that the amounts set forth in the table do not change and that all distributions are reinvested at net asset value. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

The example includes Dividends of Preferred Shares. If Dividends on Preferred Shares were not included in the example calculation, the expenses for the 1-, 3-, 5- and 10-year periods in the table above would be as follows (based on the same assumptions as above): $[    ], $[    ], $[    ] and $[    ].

USE OF PROCEEDS

We estimate the total net proceeds of the offering to be $                 based on the public offering price of $                 per share and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

Unless otherwise specified in a prospectus supplement, the Fund will invest the net proceeds of any offering in accordance with the Fund’s investment objectives and policies, and may use a portion of such proceeds, depending on market conditions, for other general corporate purposes. The Investment Adviser anticipates that the investment of the proceeds will be made in accordance with the Fund’s investment objectives and policies as appropriate investment opportunities are identified, which is expected to substantially be completed within three months; however, changes in market conditions could result in the Fund’s anticipated investment period extending to as long as six months. This could occur if market conditions are unstable to such an extent that the Investment Adviser believes market risk is greater than the benefit of making additional investments at that time. Pending such investment, the proceeds of the offering will be held in high quality short term debt securities and instruments.
