Capitalized terms used but not defined in this Addendum nor in the Agreement are defined in each Fund’s Prospectus. As used in this Addendum, the term “Prospectus” shall mean each current prospectus, including the statement of additional information, as both may be amended or supplemented, relating to Mutual Fund Share Class of any of the Funds and included in the currently effective registration statement(s) or post-effective amendment(s) thereto (the “Registration Statement”) of the Company under the Securities Act of 1933, as amended (the "1933 Act"), and the Investment Company Act of 1940, as amended (the “1940 Act”).

The Company hereby appoints the Distributor as its principal underwriter for the distribution of the Mutual Fund Share Class of each Fund, on the terms and conditions set forth in this Addendum , and the Distributor hereby accepts such appointment and agrees to perform the services and duties set forth in this Addendum.

B. During the continuous public offering of the Mutual Fund Share Class of each Fund, the Distributor shall distribute the Shares on a best efforts basis, meaning that the Distributor shall not be obligated to sell any certain number of Shares. All orders for Shares shall be made through financial intermediaries or submitted directly to the applicable Fund or its designated agent.

The Distributor agrees to furnish to the Company any comments provided by regulators with respect to such Marketing Materials.

F. At the request of the Company, the Distributor shall enter into the Standard Dealer Agreement (as defined below), and may, in its discretion, enter into non-standard dealer agreements with financial intermediaries as the Company may select, in order that such financial intermediaries may sell Shares of the Funds. The Funds’ form of dealer agreement and/or selling agreement shall be in a form similar to that attached at Exhibit D (“Standard Dealer Agreement”) and shall be approved by the Company’s Board of Directors (the “Board”).

G. The Company acknowledges and agrees that the Distributor shall not be obligated to make any payments to any broker-dealers, other financial intermediaries or other third parties, unless (i) the Distributor has received an authorized corresponding payment from the applicable Fund’s distribution and/or servicing plan adopted pursuant to Rule 12b-1 under the 1940 Act (“Plan”) and (ii) such Plan been approved by the Board.

L. Notwithstanding anything herein to the contrary, the Distributor shall not be required to register as a broker or dealer in any specific jurisdiction or to maintain its registration in any jurisdiction in which it is now registered.

M. To the extent permitted by law, the Distributor shall promptly notify the Company of the commencement of any material litigation or proceedings against the Distributor or any of its managers, officers or directors in connection with the issue and sale of any of the Shares.

N. The Distributor undertakes to perform such duties and only such duties as are expressly set forth herein, or expressly incorporated herein by reference, and no implied covenants or obligations shall be read into this Addendum against the Distributor.

3. With respect to the Mutual Fund Share Class, the duties of the Company shall be:

D. The Company shall inform the Distributor of any such states in which the Company has filed notice filings for Shares for sale under the securities laws thereof and shall promptly notify the Distributor of any change in this information.

E. The Company agrees to file from time to time such amendments to its Registration Statement and Prospectus as may be necessary in order that its Registration Statement and Prospectus will not contain any untrue statement of material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading.

F. The Company shall reasonably cooperate in the efforts of the Distributor to distribute the Shares. In addition, the Company shall keep the Distributor reasonably informed of its affairs related to the activities contemplated by this Addendum. The Company will provide to the Distributor such number of copies as Distributor may reasonably request of (i) its then currently effective Prospectus, (ii) copies of semi-annual reports and annual audited reports of the Company’s books and accounts made by independent public accountants regularly retained by the Company, and (iii) such other information or material for use in connection with the distribution of Shares. The Company shall forward a copy of any SEC filings, including the Registration Statement, to the Distributor promptly.

H. The Company shall not file any amendment to the Registration Statement or Prospectus that materially amends any provision therein which pertains to Distributor, the distribution of the Shares or the applicable sales loads or public offering price without giving Distributor reasonable advance notice thereof; provided, however, that nothing contained in this Addendum shall in any way limit the Company’s right to file at any time such amendments to the Registration Statement or Prospectus, of whatever character, as the Company may deem advisable, such right being in all respects absolute and unconditional.

I. The Company shall not list the Distributor as the principal underwriter or distributor in any post-effective amendment to the Registration Statement, which is filed for the purpose of creating a new Fund, without receiving prior written permission from the Distributor, which consent shall not be unreasonably withheld. At or before such time as a new Fund becomes effective, Client and Distributor agree to amend this Addendum for purposes of updating Exhibit A.

A. that all necessary approvals, authorizations, consents or orders of or filings with any federal, state, local or foreign governmental or regulatory commission, board, body, authority or agency have been or will be obtained by the Fund in connection with the issuance and sale of the Shares, including registration of the Shares under the 1933 Act, and any necessary qualification under the securities or blue sky laws of the various jurisdictions in which the Shares are being offered;

B. that it shall abide by the requirements of any SEC exemptive order regarding the Mutual Fund Share Class; and

C. that it shall ensure that all exchanges into or out of the Mutual Fund Share Class will be properly executed.

5. In consideration of the Distributor’s services in connection with the distribution of Shares of each Fund and Class thereof, the Distributor shall receive the compensation set forth in Exhibit C.

6. In addition to the indemnities included in the Agreement, the following indemnities shall apply with respect to the Mutual Fund Share Class:

A. The Company acknowledges and agrees that the Distributor may enter into, assume, or become a party to certain dealer, selling and/or similar agreements (“Non-Standard Dealer Agreements”) that contain certain representations, duties, obligations, undertakings and indemnification that are not included in the Standard Dealer Agreement (“Non-Standard Duties”), or lack certain representations, duties, and indemnification included in the Standard Dealer Agreement (“Non-Standard Representations,” and collectively with Non-Standard Duties, “Non-Standard Obligations”). The Company agrees to perform, or cause to perform, all such Non-Standard Obligations under any Non-Standard Dealer Agreement, subject to the Company’s review and approval of such Non-Standard Dealer Agreement. For the avoidance of doubt, any dealer or selling agreement that materially deviates from the Standard Dealer Agreement shall be considered a “Non-Standard Dealer Agreement.”

B. To the extent that the Distributor, after the review and approval by the Company, enters into any Non-Standard Dealer Agreement, the Company shall indemnify, defend and hold the Distributor Indemnitees free and harmless from and against any and all Losses that any Distributor Indemnitee may incur arising out of or relating to (a) any failure to perform any Non-Standard Obligations under any Non-Standard Dealer Agreement; (b) any representations made by the Distributor in any Non-Standard Dealer Agreement to the extent that the Distributor is not required to make such representations in the Standard Dealer Agreement; (c) any indemnification provided by the Distributor under a Non-Standard Dealer Agreement to the extent that such indemnification is beyond the indemnification that the Distributor provides to intermediaries in the Standard Dealer Agreement. In no event shall anything contained herein be so construed as to protect the Distributor Indemnitee against any liability to the Company or its shareholders to which such Distributor Indemnitee would otherwise be subject by reason of its willful misfeasance, bad faith, or gross negligence in the performance or reckless disregard of its obligations or duties under the Non-Standard Dealer Agreement to the extent that such duties and obligations are the responsibility of the Distributor in the Standard Dealer Agreement.

7. The Parties agree that the Mutual Fund Share Class will not be subject to authorized participant agreements.
