 a conversion of the Fund from a closed-end to an open-end investment company. See “Repurchase of Common Shares; Conversion to Open-End Fund” below. As noted, the voting provisions described above could have the effect of depriving Common Shareholders of an opportunity to sell their Common Shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. In the view of the Fund’s Board of Trustees, however, these provisions offer several possible advantages, including: (1) requiring persons seeking control of the Fund to negotiate with its management regarding the price to be paid for the amount of Common Shares required to obtain control; (2) promoting continuity and stability; and (3) enhancing the Fund’s ability to pursue long-term strategies that are consistent with its investment objectives and management policies. The Board of Trustees has determined that the voting requirements described above, which are generally greater than the minimum requirements under the 1940 Act, are in the best interests of the Fund’s Common Shareholders generally. A “Continuing Trustee,” as used in the discussion above, is any member of the Fund’s Board of Trustees who either (i) has been a member of the Board for a period of at least thirty-six months (or since the commencement of the Fund’s operations, if less than thirty-six months) or (ii) was nominated to serve as a member of the Board of Trustees by a majority of the Continuing Trustees then members of the Board. The foregoing is intended only as a summary and is qualified in its entirety by reference to the full text of the Declaration and the Fund’s Bylaws, both of which have been filed as exhibits to the Fund’s registration statement on file with the SEC. Liability of Trustees The Declaration provides that the obligations of the Fund are not binding upon the Trustees of the Fund individually, but only upon the assets and property of the Fund. The Declaration provides further that a Trustee or

officer shall be liable for his or her own willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the office of Trustee or officer, and for nothing else, and shall not be liable for errors of judgment or mistakes of fact or law. No provision of the Declaration, however, shall limit or eliminate any duty under the federal securities laws (including any fiduciary duties of loyalty and care) that a Trustee or officer owes to the Fund with respect to claims asserted
