ITEM 30. INDEMNIFICATION

(a) Article VI of the Registrant's Fourth Amended and Restated Agreement and Declaration of Trust provides for indemnification of officers and Trustees as follows:

SECTION 6.4 INDEMNIFICATION OF TRUSTEES, OFFICERS, ETC. Subject to and except as otherwise provided in the Securities Act of 1933, as amended, and the 1940 Act, the Trust shall indemnify each of its past, present and future Trustees and officers (including persons who serve at the Trust's request as directors, officers or trustees of another organization in which the Trust has any interest as a shareholder, creditor or otherwise (hereinafter referred to as a "Covered Person") against all liabilities, including but not limited to amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and expenses, including reasonable accountants' and counsel fees, incurred by any Covered Person in connection with the defense or disposition of any action, suit or other proceeding, whether civil, criminal, administrative or investigative, and any appeal therefrom, before any court or administrative or legislative body, in which such Covered Person may be or may have been involved as a party or otherwise or with which such person may be or may have been threatened, while in office or thereafter, by reason of being or having been such a Trustee or officer, director or trustee, and except that no Covered Person shall be indemnified against any liability to the Trust or its Shareholders to which such Covered Person would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person's office.

SECTION 6.5 ADVANCES OF EXPENSES. The Trust shall advance attorneys' fees or other expenses incurred by a Covered Person in defending a proceeding to the full extent permitted by the Securities Act of 1933, as amended, the 1940 Act, and Ohio Revised Code Chapter 1707, as amended. In the event any of these laws conflict with Ohio Revised Code Section 1701.13(E), as amended, these laws, and not Ohio Revised Code Section 1701.13(E), shall govern.

SECTION 6.6 INDEMNIFICATION NOT EXCLUSIVE, ETC. The right of indemnification provided by this Article VI shall not be exclusive of or affect any other rights to which any such Covered Person may be entitled. As used in this Article VI, "Covered Person" shall include such person's heirs, executors and administrators. Nothing contained in this article shall affect any rights to indemnification to which personnel of the Trust, other than Trustees and officers, and other persons may be entitled by contract or otherwise under law, nor the power of the Trust to purchase and maintain liability insurance on behalf of any such person.

SECTION 6.7 LIABILITY OF THIRD PERSONS DEALING WITH TRUSTEES. No person dealing with the Trustees shall be bound to make any inquiry concerning the validity of any transaction made or to be made by the Trustees or to see to the application of any payments made or property transferred to the Trust or upon its order.

(b) The Registrant may maintain a standard mutual fund and investment advisory professional and directors and officers liability policy. The policy, if maintained, would provide coverage to the Registrant, its Trustees and officers, and could cover its Advisers, among others. Coverage under the policy would include losses by reason of any act, error, omission, misstatement, misleading statement, neglect or breach of duty.

(c) Pursuant to the Underwriting Agreement ("Agreement"), the Underwriter has agreed to indemnify, defend, and hold the Registrant, its affiliates, and each of their respective trustees, officers, employees, representatives, and any person who controls or previously controlled the Registrant within the meaning of Section 15 of the 1933 Act, (collectively, the "Registrant Indemnitees") free and harmless from and against any and all losses, claims, demands, liabilities, damages and expenses (including the costs of investigating or defending any alleged losses, claims, demands, liabilities, damages or expenses and any reasonable counsel fees incurred in connection therewith) (collectively, "Losses") that any Registrant Indemnitee may incur under the 1933 Act, the 1934 Act, the 1940 Act, any other statute (including Blue Sky laws) or any rule or regulation thereunder, or under common law or otherwise arising out of or based upon (i) the Underwriter's breach of any of its obligations, representations, warranties or covenants contained in the Agreement; (ii) the Underwriter's failure to comply with any applicable securities laws or regulations; or (iii) any claim that the Registration Statement, Prospectus, sales literature and advertising materials or other information filed or made public by the Registrant (as from time to time amended) include or included an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements not misleading, insofar as such statement or omission was made in reliance upon and in conformity with information furnished to the Registrant by the Underwriter in writing. In no event shall anything contained in the Agreement be so construed as to protect the Registrant against any liability to the Underwriter to which the Registrant would otherwise be subject by reason of willful misfeasance, bad faith, or gross negligence in the performance of its duties under the Agreement or by reason of its reckless disregard of its obligations under the Agreement.

(d) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to trustees, officers and controlling persons of the Registrant pursuant to the provisions of Ohio law and the Agreement and Declaration of the Registrant or the By-Laws of the Registrant, or otherwise, the 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 the Registrant of expenses incurred or paid by a trustee, officer or controlling person of the Trust 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, 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 Act and will be governed by the final adjudication of such issue.
