You may provide proxy instructions by completing, signing and returning the enclosed proxy card (the “Proxy Card”) by mail in the enclosed envelope. The persons designated on the Proxy Card as proxies will vote your Preferred Shares as you instruct on each Proxy Card. If you return a signed Proxy Card without any voting instructions, your Preferred Shares will be voted “FOR” the Trustee nominee in accordance with the recommendation of the Board. The persons designated on the Proxy Card as proxies will also be authorized to vote (or to withhold their votes) in their discretion on any other matters which properly come before the Meeting. They may also vote in their discretion to adjourn the Meeting. If you sign and return a Proxy Card, you may still attend the Meeting to vote your Preferred Shares in person. If your Preferred Shares are held of record by a broker and you wish to vote in person at the Meeting, you should obtain a legal proxy from your broker and present it at the Meeting. You may revoke your proxy by (1) giving written notice before the Meeting of the revocation to the Fund stating that the proxy is revoked; (2) executing a subsequent proxy; or (3) attending the Meeting and voting in person. If your Preferred Shares are held in the name of your broker, you will have to make arrangements with your broker to revoke any previously executed proxy.

If the enclosed proxy card is properly executed and returned in time to be voted at the Meeting and has not been revoked, the Preferred Shares represented thereby will be voted “FOR” the Proposal listed in the Notice, unless instructions to the contrary are marked thereon, and in the discretion of the proxy holders as to the transaction of any other business that may properly come before the Meeting or any postponements or adjournments thereof. Any Shareholder who has given a proxy has the right to revoke it at any time prior to its exercise either by attending the Meeting and voting his or her Preferred Shares or by submitting a letter of revocation or a later-dated proxy to the Fund at the above address prior to the date of the Meeting. Shareholders of the Fund have no dissenters’ or appraisal rights in connection with the Proposal described herein.

Holders of a majority of the total number of outstanding Preferred Shares of the Fund entitled to vote, present in person via teleconference or by proxy, shall be required to constitute a quorum for the purpose of voting on the Proposal and any other matter which is properly presented for action by the Shareholders at the Fund’s Annual Meeting. If a quorum is not present at the Meeting, or if a quorum is present at the Meeting, but sufficient votes to approve any of the proposed items are not received, the chair of the Meeting may propose one or more adjournments of the Meeting to permit further solicitation of proxies. A Shareholder vote may be taken on the Proposal in this Proxy Statement prior to such adjournment if sufficient votes have been received for approval and it is otherwise appropriate. In the absence of a quorum, the Meeting may be adjourned by either a vote of a majority of the Preferred Shares present and entitled to vote at such meeting, or by the chair of such meeting in his or her sole discretion. If a quorum is present, the persons named as proxies will vote those proxies that they are entitled to vote “FOR” any proposal in favor of such adjournment and will vote those proxies required to be voted “AGAINST” any proposal against such adjournment.
