ITEM 30. Indemnification

Article X, Section 10.02 of the Registrant's Delaware Trust Instrument, incorporated herein as Exhibit 2 hereto, provides for the indemnification of Registrant's Trustees and officers, as follows:

Section 10.02 Indemnification.

(a) Subject to the exceptions and limitations contained in Subsection 10.02(b):

(i) every person who is, or has been, a Trustee or officer of the Trust (hereinafter referred to as a "Covered Person") shall be indemnified by the Trust to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been a Trustee or officer and against amounts paid or incurred by him in the settlement thereof;

(ii) the words "claim," "action," "suit," or "proceeding" shall apply to all claims, actions, suits or proceedings (civil, criminal or other, including appeals), actual or

threatened while in office or thereafter, and the words "liability" and "expenses" shall include, without limitation, attorneys' fees, costs, judgments, amounts paid in settlement, fines, penalties and other liabilities.

(b) No indemnification shall be provided hereunder to a Covered Person:

(i) who shall have been adjudicated by a court or body before which the proceeding was brought (A) to be liable to the Trust or its Shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office or (B) not to have acted in good faith in the reasonable belief that his action was in the best interest of the Trust; or

(ii) in the event of a settlement, unless there has been a determination that such Trustee or officer did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office, (A) by the court or other body approving the settlement; (B) by at least a majority of those Trustees who are neither Interested Persons of the Trust nor are parties to the matter based upon a review of readily available facts (as opposed to a full trial-type inquiry); or (C) by written opinion of independent legal counsel based upon a review of readily available facts (as opposed to a full trial-type inquiry).

(c) The rights of indemnification herein provided may be insured against by policies maintained by the Trust, shall be severable, shall not be exclusive of or affect any other rights to which any Covered Person may now or hereafter be entitled, shall continue as to a person who has ceased to be a Covered Person and shall inure to the benefit of the heirs, executors and administrators of such a person. Nothing contained herein shall affect any rights to indemnification to which Trust personnel, other than Covered Persons, and other persons may be entitled by contract or otherwise under law.

(d) Expenses in connection with the preparation and presentation of a defense to any claim, action, suit or proceeding of the character described in Subsection (a) of this Section 10.02 may be paid by the Trust or Series from time to time prior to final disposition thereof upon receipt of an undertaking by or on behalf of such Covered Person that such amount will be paid over by him to the Trust or Series if it is ultimately determined that he is not entitled to indemnification under this Section 10.02; provided, however, that either (i) such Covered Person shall have provided appropriate security for such undertaking, (ii) the Trust is insured against losses arising out of any such advance payments or (iii) either a majority of the Trustees who are neither Interested Persons of the Trust nor parties to the matter, or independent legal counsel in a written opinion, shall have determined, based upon a review of readily available facts (as opposed to a trial-type inquiry or full investigation), that there is reason to believe that such Covered Person will be found entitled to indemnification under this Section 10.02."

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to trustees, officers, and controlling persons or 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 Investment Company Act of 1940, as amended, 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 of 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.
