Item 25. Indemnification

Indemnification of Registrant’s principal underwriter against certain losses is provided for in Section 9 of the Distribution Agreement incorporated by reference herein as Exhibit 5(a). Indemnification of Registrant’s Custodian, Transfer Agent and Administrators is provided for, respectively, in Section 12 of the Custodian Agreement incorporated by reference herein as
Exhibit 7(a), Section 12 of the Transfer Agency Agreement incorporated by reference herein as Exhibit 8(c) and Section 9 of the Administration Agreement incorporated by reference herein as Exhibit 8(a). Registrant intends to obtain from a major insurance carrier a trustees’ and officers’ liability policy covering certain types of errors and omissions. In addition, Section 9.3 of the Registrant’s Declaration of Trust incorporated by reference herein as Exhibit 1(a) provides as follows:

Indemnification of Trustees, Officers, Representatives and Employees. The Trust shall indemnify each of its Trustees against all liabilities and expenses (including amounts paid in satisfaction of judgments, in compromise, as fines and penalties, and as counsel fees) reasonably incurred by him in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, in which he may be involved or with which he may be threatened, while as a Trustee or thereafter, by reason of his being or having been such a Trustee except with respect to any matter as to which he shall have been adjudicated to have acted in bad faith, willful misfeasance, gross negligence or reckless disregard of his duties, provided that as to any matter disposed of by a compromise payment by such person, pursuant to a consent decree or otherwise, no indemnification either for said payment or for any other expenses shall be provided unless the Trust shall have received a written opinion from independent legal counsel approved by the Trustees to the effect that if either the matter of willful misfeasance, gross negligence or reckless disregard of duty, or the matter of bad faith had been adjudicated, it would in the opinion of such counsel have been adjudicated in favor of such person. The rights accruing to any person under these provisions shall not exclude any other right to which he may be lawfully entitled, provided that no person may satisfy any right of indemnity or reimbursement hereunder except out of the property of the Trust. The Trustees may make advance payments in connection with the indemnification under this Section 9.3, provided that the indemnified person shall have given a written undertaking to reimburse the Trust in the event it is subsequently determined that he is not entitled to such indemnification.

The Trustee shall indemnify officers, representatives and employees of the Trust to the same extent that Trustees are entitled to indemnification pursuant to this Section 9.3.

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to trustees, officers and controlling persons of Registrant pursuant to the foregoing provisions, or otherwise, Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Registrant of expenses incurred or paid by a trustee, officer or controlling person of Registrant in the successful defense of any action, suit or proceeding) is asserted by such trustee,

officer or controlling person in connection with the securities being registered, 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 Act and will be governed by the final adjudication of such issue.

Section 9.6 of the Registrant’s Declaration of Trust, filed herein as Exhibit 1(a), also provides for the indemnification of shareholders of the Registrant. Section 9.6 states as follows:

Indemnification of Shareholders. In case any Shareholder or former Shareholder shall be held to be personally liable solely by reason of his being or having been a Shareholder and not because of his acts or omissions or for some other reason, the Shareholder or former Shareholder (or his heirs, executors, administrators or other legal representatives or, in the case of a corporation or other entity, its corporate or other general successor) shall be entitled out of the assets belonging to the classes of Shares with the same alphabetical designation as that of the Shares owned by such Shareholder to be held harmless from and indemnified against all loss and expense arising from such liability. The Trust shall, upon request by the Shareholder, assume the defense of any claim made against any Shareholder for any act or obligations of the Trust and satisfy any judgment thereon from such assets.
