WHEREAS, the Trust is an open-end diversified, management investment company that offers its shares exclusively to separate accounts of life insurance companies and various qualifying retirement plans or accounts;

WHEREAS, beneficial interests in the Trust are divided into several series of shares, each representing the interest in a particular managed portfolio of securities and other assets (the “Funds”);

WHEREAS, the National Life Insurance Company (the “Company”), acting on behalf of its separate accounts, purchases, holds, exchanges and redeems shares as investments for values accumulated under variable annuity contracts and variable life insurance contracts (the “Contracts”) issued through one or more separate accounts by the Company;

WHEREAS, the Company has entered into an agreement with the Trust and Sentinel Financial Services Company, as principal underwriter and distributor of the shares, regarding its purchase and redemption of shares of the Funds (the “Participation Agreement”); and

WHEREAS, with respect to each Fund, the Company is willing to provide, and Investment Adviser wishes to compensate the Company for providing, certain services with respect to the sale and distribution of the Contracts (the “Services”).

NOW, THEREFORE, for and in consideration of the promises and the mutual covenants contained herein, and for other good and valuable consideration, the receipt, adequacy and legal sufficiency of which are hereby acknowledged, the parties do hereby agree as follows:

1. Administrative Services. The Company agrees to assist Investment Adviser, as it may request from time to time, with the provision of administrative services with respect to the Trust, as they may relate to the purchase and redemption of shares of the Funds by the separate accounts of the Company listed on Schedule A. It is anticipated that such services may include (but shall not be limited to) the mailing of Trust reports, notices, proxies and proxy statements

and other informational materials to owners of the Contracts supported by the separate accounts; the transmission of purchase and redemption requests to the Trust’s transfer agent; the maintenance of separate records for each owner of a Contract reflecting shares purchased and redeemed and share balances attributable to such Contract owner in the form of units; the preparation of various reports for submission to the Trust’s Trustees; the provision of shareholder support services with respect to the Funds serving as funding vehicles for the Company’s Contracts; and the services listed on Schedule B.

2. Payment for Administrative Services. In consideration of the services to be provided by the Company, Investment Adviser shall pay the Company on a quarterly basis, from its assets, including Investment Adviser’s bona fide profits as investment adviser to the Trust, amounts equal to those described in Schedule C. For purposes of computing the payment to the Company contemplated under this Section 2 for each Fund, the average aggregate net asset value of the relevant shares of the Fund held by the separate accounts over a one-month period shall be computed by totaling the separate account’s aggregate investment (share net asset value multiplied by total number of the relevant shares held by the separate account) in each Fund on each calendar day during the month, and dividing by the total number of calendar days during such month. The payment contemplated by this Section 2 shall be calculated by Investment Adviser at the end of each calendar quarter and will be paid to the Company within sixty (60) business days thereafter.

3. Nature of Payments. The parties to this Agreement recognize and agree that Investment Adviser’s payments to the Company relate to administrative services only and do not constitute payment in any manner for investment advisory services or for costs of distribution of the Contracts or of Trust shares and are not otherwise related to investment advisory or distribution services or expenses. The Company represents that these payments are not for or related to administrative services which the Company is required to provide to owners of the Contracts by law or pursuant to the terms of the Contracts. The Parties acknowledge that there are substantial savings in administrative expenses to the Trust by virtue of having a separate account as the sole shareholder in a Fund rather than multiple accounts reflecting the separate account’s investment. The Company represents that:

· it may legally receive the payments contemplated by this Agreement.

· the administrative services provided under this Agreement are not services that the Trust has agreed to perform, provide or pay for under the Participation Agreement.

· to the extent required by applicable law, the Company has taken payments received from Investment Adviser under this Agreement into account in making any determinations pursuant to Section 26(f)(2)(A) and 26(f)(3) of the Investment Company Act of 1940, as amended (the “Act”).

4. Term. This Agreement shall remain in full force and effect for an initial term of one year from the date hereof, and shall automatically renew for successive one-year periods unless either party notifies the other upon sixty (60) days’ written notice of its intent not to continue this Agreement. This Agreement shall terminate automatically with respect to a Fund

upon (i) the redemption of the Separate Account’s investment in the Fund, or (ii) upon termination of the Trust’s obligation to sell shares of a Fund under the Participation Agreement.

5. Representations and Warranties of the Company. The Company represents and warrants that:

(a) it is an insurance company duly organized and in good standing under Vermont insurance law;

(b) its entering into and performing its obligations under this Agreement does not and will not violate its charter documents or by-laws, rules or regulations, or any agreement to which it is a party; and

(c) it will keep confidential any information acquired in connection with the matters contemplated by this Agreement regarding the business and affairs of the Trust, Investment Adviser and their affiliates.

6. Representations and Warranties of Investment Adviser. Investment Adviser represents and warrants that:

(a) it is a corporation duly organized and in good standing under Vermont law;

(c) it will keep confidential any information acquired in connection with the matters contemplated by this Agreement regarding the business and affairs of the Company and its affiliates, however, nothing in this provision shall restrict Investment Adviser or any of its affiliates from engaging in any financing, investment banking, asset management, trading, market making, arbitrage, brokerage, or any other activities it conducts or in which it seeks to engage in the ordinary course of business.

7. Interpretation. This Agreement shall be construed in accordance with the laws of the State of Delaware, without giving effect to the principles of conflicts of laws, subject to the following rules:

(a) This Agreement shall be subject to the provisions of the Act, and the rules, regulations and rulings thereunder, including such exemptions from that statute, rules and regulations as the Securities and Exchange Commissioner (the “SEC”) may grant, and the terms herein shall be limited, interpreted and construed in accordance therewith.

(b) The captions in this Agreement are included for convenience of reference and in no way define or delineate any of the provisions herein or otherwise affect their construction or effect.
