* A non-U.S. Preferred Shareholder should NOT complete and return the attached Form W-9, but should instead contact the Tender Agent or its broker, dealer, commercial bank, trust company or other nominee for the appropriate certification (e.g., W-8BEN, W-8BEN-E, W-8ECI or W-8EXP). A non-U.S. Preferred Shareholder is any shareholder other than (i) a citizen or resident of the U.S., (ii) a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes), partnership or other entity created or organized in or under the laws of the U.S., any State or any political subdivision thereof, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of the source of the income, or (iv) a trust if it (x) is subject to the supervision of a court within the U.S. and one or more U.S. persons has the authority to control all substantial decisions of the trust or (y) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

1. Guarantee of Signatures. Except as otherwise provided below, all signatures on this Letter of Transmittal must be guaranteed by a financial institution (including most banks, savings and loan associations and brokerage houses) that is a member of a recognized Medallion Program approved by The Securities Transfer Association, Inc., including the Securities Transfer Agents Medallion Program (STAMP), or any other “eligible guarantor institution” (as such term is defined in Rule 17Ad-15 under the Securities Exchange Act of 1934, as amended) (each an “Eligible Institution”). Signatures on this Letter of Transmittal need not be guaranteed if such Preferred Shares are tendered for the account of an Eligible Institution. See Instruction 5.

2. Delivery of Preferred Shares. Delivery of Preferred Shares is to be made by book-entry delivery pursuant to the procedures set forth in Section 3 of the Offer to Purchase; an Agent’s Message (as defined in the Offer to Purchase) should be utilized. A confirmation of a book-entry transfer into the Depositary’s account at the Book-Entry Transfer Facility of all Preferred Shares delivered electronically, as well as an Agent’s Message, and any other documents required by this Letter of Transmittal, must be received by the Depositary at its address set forth on the front page of this Letter of Transmittal by the Expiration Date (as defined in the Offer to Purchase). Preferred Shareholders who cannot deliver their Preferred Shares and all other required documents to the Depositary by the Expiration Date must tender their Preferred Shares pursuant to the guaranteed delivery procedure set forth in Section 3 of the Offer to Purchase. Pursuant to such procedure: (i) such tender must be made by or through an Eligible Institution, (ii) a properly completed and duly executed Notice of Guaranteed Delivery substantially in the form provided by the Fund must be received by the Depositary by the Expiration Date and (iii) a properly completed and duly executed Letter of Transmittal (or facsimile thereof) with any required signature guarantee or an Agent’s Message and any other documents required by the Letter of Transmittal and, for Preferred Shares held in street name, confirmation of a book-entry transfer of such Preferred Shares into the Depositary’s account at the Book-Entry Transfer Facility, must be received by the Depositary within two NYSE trading days after the date of execution of the Notice of Guaranteed Delivery, all as provided in Section 3 of the Offer to Purchase.

The method of delivery of any documents is at the option and risk of the tendering Preferred Shareholder. If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery.

No alternative, conditional or contingent tenders will be accepted, and no fractional Preferred Shares will be purchased. By executing this Letter of Transmittal, the tendering Preferred Shareholder waives any right to receive any notice of the acceptance for payment of the Preferred Shares.

3. Partial Tenders. If any tendered Preferred Shares are not accepted for payment pursuant to the terms and conditions of the Offer for any reason, or if any tendered Preferred Shares are not accepted because of an invalid tender, or if any tendered Preferred Shares are properly withdrawn, Preferred Shares will be returned to the appropriate account at the Book-Entry Transfer Facility without charge by the Fund to the tendering Preferred Shareholder, as soon as practicable following expiration or termination of the Offer or the proper withdrawal of the Preferred Shares.

4. Stock Transfer Taxes. The amount of any stock or share transfer taxes imposed in respect of Preferred Shares tendered in connection with the Offer, including, without limitation, such taxes imposed for a reason other than the sale or transfer of Preferred Shares to the Fund pursuant to its Offer, whether such taxes are imposed on the registered holder(s), any other person to whom shares are to be returned or the purchase price is to be paid, or otherwise, including any such taxes due in respect of (a) shares tendered but not purchased, including such shares that are to be returned in the name of a person other than the registered holder(s), or (b) shares the purchase price for which is paid to a person other than the registered holder(s), will be for the Preferred Shareholder’s account and will not be borne by the Fund.

5. Substitute Form W-9. Under U.S. federal income tax law, a backup withholding tax may be imposed on the gross proceeds otherwise payable to certain Preferred Shareholders pursuant to the Offer. In order to avoid such backup withholding, each tendering Preferred Shareholder must provide the applicable withholding agent with such Preferred Shareholder’s correct taxpayer identification number and certify that such Preferred Shareholder is not subject to such backup withholding by completing the Substitute Form W-9 set forth above (or, in the case of a

foreign Preferred Shareholder, an appropriate IRS Form W-8 or Substitute Form W-8). In general, if a Preferred Shareholder is an individual, the taxpayer identification number is the Social Security number of such individual. If the applicable withholding agent is not provided with the correct taxpayer identification number, the Preferred Shareholder or payee will be subject to a $50 penalty imposed by the Internal Revenue Service unless the failure to provide the correct number is due to reasonable cause and not willful neglect. A false statement made on the Substitute Form W-9 without any reasonable basis that results in no backup withholding will be subject to a $500 penalty, and the willful falsification of certifications or affirmations may be subject to criminal penalties, including fines and/or imprisonment. Certain Preferred Shareholders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. However, such Preferred Shareholders should complete the Substitute Form W-9 (or, in the case of a foreign Preferred Shareholders, an appropriate IRS Form W-8 or Substitute Form W-8) to avoid erroneous backup withholding. For further information concerning backup withholding and instructions for completing the Substitute Form W-9 (including how to obtain a taxpayer identification number if you do not have one and how to complete the Substitute Form W-9 if Preferred Shares is held in more than one name), consult the Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9.

Foreign persons should not complete a Substitute Form W-9. Instead, in order to establish that a foreign person qualifies as an exempt recipient for which backup withholding is not required, such person should submit an appropriate IRS Form W-8 or Substitute Form W-8, attesting to its status. These forms can be obtained from the Depositary or from the relevant broker, dealer, commercial bank, trust company or other nominee.

Backup withholding is not an additional federal income tax. Rather, the federal income tax liability of a person subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is furnished to the Internal Revenue Service. NOTE: FAILURE TO COMPLETE AND RETURN THE SUBSTITUTE FORM W-9 (OR AN APPROPRIATE IRS FORM W-8 OR SUBSTITUTE FORM W-8) MAY RESULT IN PENALTIES AND BACKUP WITHHOLDING ON ANY AMOUNTS OTHERWISE PAYABLE TO YOU PURSUANT TO THE OFFER. PLEASE REVIEW THE GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER ON SUBSTITUTE FORM W-9 FOR ADDITIONAL DETAILS.

6. Waiver of Conditions. Subject to the Offer to Purchase, the conditions of the Offer may be waived, in whole or in part, by the Fund, at any time and from time to time, in the case of any Preferred Shares tendered.

7. Irregularities. The Fund will determine, in its sole discretion, all questions as to the number of Preferred Shares to be accepted, and the validity, form, eligibility, including time of receipt, and acceptance for payment of any tender of Preferred Shares. The Fund’s determination will be final and binding on all parties. The Fund reserves the absolute right to reject any or all tenders it determines not to be in proper form or the acceptance of or payment for which it determines may be unlawful. The Fund also reserves the absolute right to waive any defect or irregularity in the tender of any particular Preferred Shares or any particular Preferred Shareholder. No tender of Preferred Shares will be deemed to be properly made until all defects or irregularities have been cured by the tendering Preferred Shareholder or waived by the Fund. None of the Fund, the Depositary, the Tender Agent, or any other person will be under any duty to give notice of any defects or irregularities in any tender, or incur any liability for failure to give any such notice. The Fund’s interpretation of the terms of and conditions to the Offer, including this Letter of Transmittal and the instructions thereto, will be final and binding. By tendering Preferred Shares to the Fund, you agree to accept all decisions the Fund makes concerning these matters and waive any right you might otherwise have to challenge those decisions.

8. Acceptance of Tendered Shares. If a Preferred Shareholder tenders all of his or her Preferred Shares, all such Preferred Shares credited to such Preferred Shareholder’s account(s) will be tendered unless the Preferred Shareholder otherwise specifies.

9. Contact Information. In order to facilitate the Offer and any auctions for Preferred Shares that may remain outstanding after the Offer is completed, each broker or other Nominee Holder must provide additional contact information for its auction department, or whoever at the broker or other Nominee Holder submits auction instructions for the Preferred Shares on its behalf, and/or the broker-dealer, if a different party, that submits those auction instructions to the Auction Agent. If you are unable to provide this contact information, the Fund, in its sole discretion, may waive this requirement.

Any questions and requests for assistance may be directed to the Tender Agent at its address and telephone number set forth on the first page of this Letter of Transmittal. Additional copies of the Offer to Purchase, the Letter of Transmittal and Notice of Guaranteed Delivery may be obtained from the Tender Agent at its address and telephone number set forth on the first page of this Letter of Transmittal.
