INVESTMENT COMPANY ACT OF 1940

1. Introduction

The Fund, on behalf of its series listed in Appendix A, as may be amended from time to time (individually and collectively, the “Series”), and VP Distributors, LLC (the “Distributor”), a broker-dealer registered under the Securities Exchange Act of 1934, have entered into a Distribution Agreement pursuant to which the Distributor acts as principal underwriter of each Series and class of shares of the Fund for sale to the permissible purchasers. The Trustees of the Fund have determined to adopt this Amended and Restated Distribution Plan (the “Plan”), in accordance with the requirements of Rule 12b-1 of the Investment Company Act of 1940, as amended (the “Act”) with respect to the Class A shares of the Series and have determined that there is a reasonable likelihood that the Plan will benefit the Fund and its Class A shareholders.

2. Rule 12b-1 Fees

The Fund shall pay to the Distributor, at the end of each month, an amount on an annual basis equal to 0.25% of the average daily value of the net assets of the Class A shares of any Series, as compensation for the Distributor’s services as distributor of the Fund in connection with any activities or expenses primarily intended to result in the sale of the Class A shares of the Series. Expenses may include, but are not limited to, payment of compensation, including incentive compensation to securities dealers and financial institutions and organizations to obtain various distribution related and/or shareholder services for the purchasers of variable annuity or variable life insurance contracts (“Variable Contracts”) investing indirectly in Class A shares of the Series; payment of compensation to and expenses of personnel of the Distributor who support the distribution of Class A shares of the Series; expenses related to the cost of financing or providing such financing from the Distributor’s or an affiliate’s resources in connection with the Distributor’s payment of such distribution expenses and the payment of other direct distribution costs such as the cost of sales literature, advertising and prospectuses. Shareholder services include, but are not limited to, transmitting prospectuses, statements of additional information, shareholder reports, proxy statements and other materials to prospective purchasers of Variable Contracts investing indirectly in Class A shares of the Series; providing educational materials; providing facilities to answer questions about the Series; receiving and answering correspondence; assisting prospective purchasers of Variable Contracts investing indirectly in Class A shares of the Series in completing application forms and selecting account options; and providing such other information and services as the Distributor or Series may reasonable request.
