OTHER INFORMATION

ITEM 15. INDEMNIFICATION

Reference is made to Article VIII, Section 2 of the Registrant's Amended and Restated Agreement and Declaration of Trust (the "Declaration of Trust"), incorporated by reference as Exhibit (a)(2) hereto, and to Section 7 of the Registrant's Distribution Agreement, incorporated by reference as Exhibit (h)(1) hereto. The Registrant hereby undertakes that it will comply with the indemnification provisions of the Declaration of Trust and Distribution Agreement in a manner consistent with Release 40-11330 of the Securities and Exchange Commission (the "SEC") under the Investment Company Act of 1940, as amended (the "1940 Act"), so long as the interpretation therein of Sections 17(h) and 17(i) of the 1940 Act remains in effect.

The Registrant has entered into indemnification agreements with certain officers of the Fund, which provide specific rights and obligations with respect to the indemnification of such officers. Each indemnification agreement is filed as an exhibit to this Registration Statement.

The Registrant maintains insurance on behalf of any person who is or was an independent trustee, officer, employee, or agent of the Registrant against certain liability asserted against and incurred by, or arising out of, his or her position. However, in no event will the Registrant pay that portion of the premium, if any, for insurance to indemnify any such person for any act for which the Registrant itself is not permitted to indemnify.

Insofar as indemnification for liability arising under the Securities Act of 1933, as amended (the "1933 Act"), may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the 1933 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the 1933 Act and will be governed by the final adjudication of such issue.
