HOW DOES THE BOARD RECOMMEND THAT I VOTE?

The Board recommends that you vote FOR the proposal.

WHY SHOULD I VOTE?

Every vote is important. If shareholders fail to vote their proxies, the fund may not receive enough votes to go forward with the April 16, 2012 shareholder meeting. If this happens, additional solicitations may have to be made to obtain a quorum, or proxies may have to be resent to shareholders, which will result in additional expense to the fund.

WHO HAVE WE CONTRACTED FOR THE SERVICES OF A PROXY SOLICITOR?

We have hired Computershare Fund Services as the Fund’s proxy solicitor. If we do not receive your vote after a reasonable amount of time, you may receive a telephone call from them reminding you to vote your shares.

WILL MY VOTE BE CONFIDENTIAL USING THE ONLINE PROXY VOTING SYSTEM?

The Web proxy voting system offered by proxy-direct.com maintains a high level of security to ensure the confidentiality of your vote. Security features include:

	•		Secure Sockets Layer (SSL)— A security measure that encrypts all information that travels between proxy-direct.com Web server and the shareholder’s computer.

	•		Control Number— Each shareholder is required to enter his or her control number. proxy-direct.com verifies the number and presents the holder with the proxy card.

	•		Firewall— To protect the confidentiality of your account records, proxy-direct.com uses only control numbers and card codes to register votes. Voted positions are then periodically uploaded to our master database of shareholders listed as of the record date. All account-specific data remains behind our firewall.

HOW DO I SIGN THE PROXY CARD?

The following general rules for signing proxy cards may be of assistance to you and could help avoid the time and expense involved in validating your vote if you fail to sign your proxy card properly.

Individual and Joint Accounts:Shareholders and joint owners should sign exactly as their name appears in the account registration shown on the proxy card.

All Other Accounts:The capacity of the individual signing the proxy card (for example, “trustee”) should be indicated unless it is reflected in the form of registration. If a corporation, limited liability company, or partnership, please sign full entity name and indicate the signer’s position with the entity.
