Item 30. Indemnification

Article IV of the Registrant’s Third Amended and Restated Agreement and Declaration of Trust provides as follows:

4.1 No Personal Liability of Shareholders, Trustees, etc. No Shareholder of the Trust shall be subject in such capacity to any personal liability whatsoever to any Person in connection with Trust Property or the acts, obligations or affairs of the Trust. Shareholders shall have the same limitation of personal liability as is extended to stockholders of a private corporation for profit incorporated under the general corporation law of the State of Delaware. No Trustee or officer of the Trust shall be subject in such capacity to any personal liability whatsoever to any Person, other than the Trust or its Shareholders, in connection with Trust Property or the affairs of the Trust, save only liability to the Trust or its Shareholders arising from bad faith, willful misfeasance, gross negligence or reckless disregard for his duty to such Person; and, subject to the foregoing exception, all such Persons shall look solely to the Trust Property for satisfaction of claims of any nature arising in connection with the affairs of the Trust. If any Shareholder, Trustee or officer, as such, of the Trust, is made a party to any suit or proceeding to enforce any such liability, subject to the foregoing exception, he shall not, on account thereof, be held to any personal liability.

4.2 Mandatory Indemnification. (a) The Trust shall indemnify the Trustees and officers of the Trust (each such person being an “indemnitee”) against any liabilities and expenses, including amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and reasonable counsel fees reasonably incurred by such indemnitee in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, before any court or administrative or investigative body in which he may be or may have been involved as a party or otherwise (other than, except as authorized by the Trustees, as the plaintiff or complainant) or with which he may be or may have been threatened, while acting in any capacity set forth above in this Section 4.2 by reason of his having acted in any such capacity, except with respect to any matter as to which he shall not have acted in good faith in the reasonable belief that his action was in the best interest of the Trust or, in the case of any criminal proceeding, as to which he shall have had reasonable cause to believe that the conduct was unlawful, provided,

however, that no indemnitee shall be indemnified hereunder against any liability to any person or any expense of such indemnitee arising by reason of (i) willful misfeasance, (ii) bad faith, (iii) gross negligence (negligence in the case of Affiliated Indemnitees), or (iv) reckless disregard of the duties involved in the conduct of his position (the conduct referred to in such clauses (i) through (iv) being sometimes referred to herein as “disabling conduct”). Notwithstanding the foregoing, with respect to any action, suit or other proceeding voluntarily prosecuted by any indemnitee as plaintiff, indemnification shall be mandatory only if the prosecution of such action, suit or other proceeding by such indemnitee was authorized by a majority of the Trustees.

(b) Notwithstanding the foregoing, no indemnification shall be made hereunder unless there has been a determination (1) by a final decision on the merits by a court or other body of competent jurisdiction before whom the issue of entitlement to indemnification hereunder was brought that such indemnitee is entitled to indemnification hereunder or, (2) in the absence of such a decision, by (i) a majority vote of a quorum of those Trustees who are neither Interested Persons of the Trust nor parties to the proceeding (“Disinterested Non-Party Trustees”), that the indemnitee is entitled to indemnification hereunder, or (ii) if such quorum is not obtainable or even if obtainable, if such majority so directs, independent legal counsel in a written opinion conclude that the indemnitee should be entitled to indemnification hereunder. All determinations to make advance payments in connection with the expense of defending any proceeding shall be authorized and made in accordance with the immediately succeeding paragraph (c) below.

(c) The Trust shall make advance payments in connection with the expenses of defending any action with respect to which indemnification might be sought hereunder if the Trust receives a written affirmation by the indemnitee of the indemnitee’s good faith belief that the standards of conduct necessary for indemnification have been met and a written undertaking to reimburse the Trust unless it is subsequently determined that he is entitled to such indemnification and if a majority of the Trustees determine that the applicable standards of conduct necessary for indemnification appear to have been met. In addition, at least one of the following conditions must be met: (1) the indemnitee shall provide adequate security for his undertaking, (2) the Trust shall be insured against losses arising by reason of any lawful advances, or (3) a majority of a quorum of the Disinterested Non-Party Trustees, or if a majority vote of such quorum so direct, independent legal counsel in a written opinion, shall conclude, based on a review of readily available facts (as opposed to a full trial-type inquiry), that there is substantial reason to believe that the indemnitee ultimately will be found entitled to indemnification.

(d) The rights accruing to any indemnitee under these provisions shall not exclude any other right to which he may be lawfully entitled.

(e) Notwithstanding the foregoing, subject to any limitations provided by the 1940 Act and this Declaration, the Trust shall have the power and authority to indemnify Persons providing services to the Trust to the full extent provided by law as if the Trust were a corporation organized under the Delaware General Corporation Law provided that such indemnification has been approved by a majority of the Trustees.

4.3 No Duty of Investigation; Notice in Trust Instruments, etc. No purchaser, lender, transfer agent or other person dealing with the Trustees or with any officer, employee or agent of the Trust shall be bound to make any inquiry concerning the validity of any transaction purporting to be made by the Trustees or by said officer, employee or agent or be liable for the application of money or property paid, loaned, or delivered to or on the order of the Trustees or of said officer, employee or agent. Every obligation, contract, undertaking, instrument, certificate, Share, other security of the Trust, and every other act or thing whatsoever executed in connection with the Trust shall be conclusively taken to have been executed or done by the executors thereof only in their capacity as Trustees under this Declaration or in their capacity as officers, employees or agents of the Trust. The Trustees may maintain insurance for the protection of the Trust Property, its Shareholders, Trustees, officers, employees and agents in such amount as the Trustees shall deem adequate to cover possible liability, and such other insurance as the Trustees in their sole judgment shall deem advisable or is required by the 1940 Act.

4.4 Reliance on Experts, etc. Each Trustee and officer or employee of the Trust shall, in the performance of its duties, be fully and completely justified and protected with regard to any act or any failure to act resulting from reliance in good faith upon the books of account or other records of the Trust, upon an opinion of counsel, or upon reports made to the Trust by any of the Trust’s officers or employees or by any advisor, administrator, manager, distributor, selected dealer, accountant, appraiser or other expert or consultant selected with reasonable care by the Trustees, officers or employees of the Trust, regardless of whether such counsel or other person may also be a Trustee.

Section 9 of the Registrant’s Investment Advisory Agreement provides as follows:

9. Indemnity

(a) The Fund hereby agrees to indemnify the Adviser and each of the Adviser’s trustees, officers, employees, and agents (including any individual who serves at the Adviser’s request as director, officer, partner, trustee or the like of another corporation) and controlling persons (each such person being an “indemnitee”) against any liabilities and expenses, including amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and counsel fees (all as provided in accordance with applicable corporate law) reasonably incurred by such indemnitee in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, before any court or administrative or investigative body in which he may be or may have been involved as a party or otherwise or with which he may be or may have been threatened, while acting in any capacity set forth above in this paragraph or thereafter by reason of his having acted in any such capacity, except with respect to any matter as to which he shall have been adjudicated not to have acted in good faith in the reasonable belief that his action was in the best interest of the Fund and furthermore, in the case of any criminal proceeding, so long as he had no reasonable cause to believe that the conduct was unlawful, provided, however, that (1) no indemnitee shall be indemnified hereunder against any liability to the Fund or its shareholders or any expense of such indemnitee arising by reason of (i) willful misfeasance, (ii) bad faith, (iii) gross negligence, (iv) reckless disregard of the duties involved in the conduct of his position (the conduct referred to in such clauses (i) through (iv) being sometimes referred to herein as “disabling conduct”), (2) as to any matter disposed of by settlement or a compromise payment by such indemnitee, pursuant to a consent decree or otherwise, no indemnification either for said payment or for any other expenses shall be provided unless there has been a determination that such settlement or compromise is in the best interests of the Fund and that such indemnitee appears to have acted in good faith in the reasonable belief that his action was in the best interest of the Fund and did not involve disabling conduct by such indemnitee and (3) with respect to any action, suit or other proceeding voluntarily prosecuted by any indemnitee as plaintiff, indemnification shall be mandatory only if the prosecution of such action, suit or other proceeding by such indemnitee was authorized by a majority of the full Board of the Fund. Notwithstanding the foregoing the Fund shall not be obligated to provide any such indemnification to the extent such provision would waive any right which the Fund cannot lawfully waive.

(b) The Fund shall make advance payments in connection with the expenses of defending any action with respect to which indemnification might be sought hereunder if the Fund receives a written affirmation of the indemnitee’s good faith belief that the standard of conduct necessary for indemnification has been met and a written undertaking to reimburse the Fund unless it is subsequently determined that he is entitled to such indemnification and if the trustees of the Fund determine that the facts then known to them would not preclude indemnification. In addition, at least one of the following conditions must be met: (A) the indemnitee shall provide a security for his undertaking, (B) the Fund shall be insured against losses arising by reason of any lawful advances, or (C) a majority of a quorum of trustees of the Fund who are neither “interested persons” of the Fund (as defined in Section 2(a)(19) of the Act) nor parties to the proceeding (“Disinterested Non-Party Trustees”) or an independent legal counsel in a written opinion, shall determine, based on a review of readily available facts (as opposed to a full trial-type inquiry), that there is reason to believe that the indemnitee ultimately will be found entitled to indemnification.

(c) All determinations with respect to indemnification hereunder shall be made (1) by a final decision on the merits by a court or other body before whom the proceeding was brought that such indemnitee is not liable by reason of disabling conduct or, (2) in the absence of such a decision, by (i) a majority vote of a quorum of the Disinterested Non-party Trustees of the Fund, or (ii) if such a quorum is not obtainable or even, if obtainable, if a majority vote of such quorum so directs, independent legal counsel in a written opinion.

The rights accruing to any indemnitee under these provisions shall not exclude any other right to which he may be lawfully entitled.

Other

Reference is made to Section 7 of the Sales Agreement, which is filed as Exhibit (h)(i) to this Registration Statement.

Additional underwriting indemnification provisions, if any, to be added by amendment.

Additionally, the Registrant and the other funds in the Gabelli/GAMCO Fund Complex jointly maintain, at their own expense, E&O/D&O insurance policies for the benefit of its directors/trustees, officers and certain affiliated persons. The Registrant pays a pro rata portion of the premium on such insurance policies.

Insofar as indemnification for liability arising under the Securities Act of 1933 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 Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities 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 Securities Act and will be governed by the final adjudication of such issue.
