1.

Such activities and services will relate to the sale, promotion and marketing of the Investor A1 Shares of each Fund. Such expenditures may consist of sales commissions to financial intermediaries for selling Investor A1 Shares, compensation, sales incentives and payments to sales and marketing personnel, and the payment of expenses incurred in its sales and promotional activities, including advertising expenditures related to the Fund and the costs of preparing and distributing promotional materials. The distribution fee may also be used to pay the financing costs of carrying the unreimbursed expenditures described in this Paragraph 2. Payment of the distribution fee described in this Paragraph 2 shall be subject to any limitations set forth in any applicable regulation of the Financial Industry Regulatory Authority, Inc.

3. The Distributor shall provide each Fund for review by the Board of Directors, and the Directors shall review at least quarterly, a written report complying with the requirements of Rule 12b-1 regarding the disbursement of the account maintenance fee and distribution fee during such period.

4. This Plan shall not take effect with respect to a Fund until it has been approved by votes of a majority of both (a) the Directors of the Fund and (b) those Directors of the Fund who are not “interested persons” of the Fund, as defined in the Investment Company Act, and have no direct or indirect financial interest in the operation of this Plan or any agreements related to it (the Rule 12b-1 Directors), cast in person at a meeting or meetings called for the purpose of voting on the Plan and such related agreements.

5. The Plan shall continue in effect for so long as such continuance is specifically approved at least annually in the manner provided for approval of the Plan in paragraph 4.

6. The Plan may be terminated at any time with respect to any Fund or vote of a majority of the Rule 12b-1 Directors, or by vote of a majority of the outstanding Investor A1 Shares voting securities of the applicable Fund.

7. The Plan may not be amended to increase materially the rate of payments provided for in Paragraphs 1 or 2 hereof with respect to any Fund unless such amendment is approved by at least a majority, as defined in the Investment Company Act, of the outstanding Investor A1 Shares voting securities of the applicable Fund, and by the Directors of the Fund in the manner provided for in Paragraph 4 hereof, and no material amendment to the Plan shall be made unless approved in the manner provided for approval and annual renewal in Paragraph 4 hereof.

8. While the Plan is in effect with respect to any Fund, the selection and nomination of Directors who are not interested persons, as defined in the Investment Company Act, of the Fund shall be committed to the discretion of the Directors who are not interested persons.

9. The Fund shall preserve copies of the Plan and any related agreements and all reports made pursuant to paragraph 3 hereof, for a period of not less than six years from the date of the Plan, or the date of such agreement or report, as the case may be, the first two years in an easily accessible place.

10. The Declaration of Trust establishing each Fund that is organized as a Massachusetts business trust, together with all amendments thereto (the “Declaration”), which is on file in the office of the Secretary of the Commonwealth of Massachusetts, provides that the name of the Fund refers to the Trustees under the Declaration collectively as Trustees, but not as individuals or personally; and no Trustee, shareholder, officer, employee or agent of a Fund shall be held to any personal liability, not shall resort be had to their private property for the satisfaction of any obligation or claim or otherwise in connection with the affairs of a Fund, but the trust property only shall be liable.
