WHEREAS, the Company has registered or will register each Account as a unit investment trust under the 1940 Act; and

WHEREAS, the Company desires to utilize shares of one or more Portfolios as an investment vehicle of the Accounts;

NOW, THEREFORE, in consideration of their mutual promises, the parties agree as follows:

ARTICLE I

Sale of Trust Shares

1.1 The Trust shall make shares of its Portfolios listed on Schedule B available to the Accounts at the net asset value next computed after receipt of such purchase order by the Trust (or its agent), as established in accordance with the provisions of the then current prospectus of the Trust. Shares of a particular Portfolio of the Trust shall be ordered in such quantities and at such times as determined by the Company to be necessary to meet the requirements of the Contracts. The Trustees of the Trust (the “Trustees”) may refuse to sell Shares of any Portfolio to any person, or suspend or terminate the offering of Shares of any Portfolio if such action is required by law or by regulatory authorities having jurisdiction or is, in the sole discretion of the Trustees acting in good faith and in light of their fiduciary duties under federal and any applicable state laws, necessary in the best interests of the shareholders of such Portfolio.

1.2 The Trust will redeem any full or fractional shares of any Portfolio when requested by the Company on behalf of an Account at the net asset value next computed after receipt by the Trust (or its agent) of the request for redemption, as established in accordance with the provisions of the then current prospectus of the Trust. The Trust shall make payment for such Shares in the manner established from time to time by the Trust, but in no event shall payment be delayed for a greater period than is permitted by the 0000 Xxx.

1.3 For the purposes of Sections 1.1 and 1.2, the Trust hereby appoints the Company as its agent for the limited purpose of receiving and accepting purchase and redemption orders resulting from investment in the payments under the Contracts. Receipt by the Company shall constitute receipt by the Trust provided that i) such orders are received by the Company in good order prior to the time the net asset value of each Portfolio is priced in accordance with its prospectus and ii) the Trust receives notice of such orders by 10:00 a.m. New York time on the next following Business Day. “Business Day” shall mean any day on which the New York Stock Exchange is open for trading and on which the Trust calculates its net asset value pursuant to the rules of the Securities and Exchange Commission.

1.4 Purchase orders that are transmitted to the Trust in accordance with Section 1.3 shall be paid for no later than 3:00 p.m. New York time on the same Business Day that the Trust receives notice of the order. Payments shall be made in federal funds transmitted by wire.

1.5 Issuance and transfer of the Trust’s Shares will be by book entry only. Stock certificates will not be issued to the Company or the Account. Shares ordered from the Trust will be recorded in the appropriate title for each Account or the appropriate subaccount of each Account.

1.6 The Trust shall furnish prompt notice to the Company of any income dividends or capital gain distributions payable on the Trust’s Shares. The Company hereby elects to receive all such income dividends and capital gain distributions as are payable on a Portfolio’s Shares in additional Shares of that Portfolio. The Trust shall notify the Company of the number of Shares so issued as payment of such dividends and distributions.

1.7 The Trust shall make the net asset value per Share for each Portfolio available to the Company on a daily basis as soon as reasonably practical after the net asset value per Share is calculated and shall use its best efforts to make such net asset value per Share available by 6 p.m. New York time. If the Trust provides the Company with materially incorrect share net asset value information, the Trust shall make an adjustment to the number of shares purchased or redeemed for the Accounts to reflect the correct share net asset value per share. Any material error in the calculation or reporting of net asset value per share, dividend or capital gains information shall be reported promptly upon discovery to the Company.

1.8 The Trust agrees that its Shares will be sold only to Participating Insurance Companies and their separate accounts and to certain qualified pension and retirement plans to the extent permitted by the Exemptive Order. No Shares of any Portfolio will be sold directly to the general public. The Company agrees that Trust Shares will be used only for the purposes of funding the Contracts and Accounts listed in Schedule A, as amended from time to time.

1.9 The Trust agrees that all Participating Insurance Companies shall have the obligations and responsibilities regarding pass-through voting and conflicts of interest corresponding to those contained in Section 2.8 and Article IV of this Agreement.

1.10 All orders accepted by the Company shall be subject to the terms of the then current prospectus of each Portfolio, including without limitation, policies regarding minimum account sizes, market timing and excessive trading. The Company shall use its best efforts, and shall reasonably cooperate with, the Trust to enforce stated prospectus policies regarding transactions in Shares, particularly those related to market timing. The Company acknowledges that orders accepted by it in violation of the Trust’s stated policies may be subsequently revoked or cancelled by the Trust and that the Trust shall not be responsible for any losses incurred by the Company or Contract or Account as a result of such cancellation. The Trust or its agent shall notify the Company of such cancellation prior to 12:00 p.m. EST on the next day following Business Day after any such cancellation.

In addition, the Company acknowledges that the Trust has the right to refuse any purchase order for any reason, particularly if the Trust determines that a Portfolio would be unable to invest the money effectively in accordance with its investment policies or would otherwise be adversely affected due to the size of the transaction, frequency of trading by the account or other factors. The Trust agrees to cooperate with the Company in establishing and communicating to the Company parameters for trades that the Trust will consider to be market timing activity prior to rejecting any trades. The Trust agrees to provide the Company with a written warning of its intention to begin rejecting trades before it begins rejecting trades due to market timing.

1.11 The Trust shall provide the Company account look-up access through DST Vision or a similar electronic look-up feature to review daily account balances.

3.2 The Company represents and warrants that each Account has been registered or, prior to any issuance or sale of the Contracts, will be registered as a unit investment trust in accordance with the provisions of the 0000 Xxx.

3.3 The Company represents and warrants that the Contracts or interests in the Accounts (1) are or, prior to issuance, will be registered as securities under the 1933 Act or, alternatively (2) are not registered because they are properly exempt from registration under the 1933 Act or will be offered exclusively in transactions that are properly exempt from registration under the 1933 Act.

ARTICLE IV

Potential Conflicts

4.1 The parties acknowledge that the Trust’s shares may be made available for investment to other Participating Insurance Companies. In such event, the Trustees will monitor the Trust for the existence of any material irreconcilable conflict between the interests of the contract owners of all Participating Insurance Companies. An irreconcilable material conflict may arise for a variety of reasons, including: (a) an action by any state insurance regulatory authority (b) a change in applicable federal or state insurance, tax, or securities laws or regulations, or a public ruling, private letter ruling, no-action or interpretative letter, or any similar action by insurance, tax, or securities regulatory authorities; (c) an administrative or judicial decision in any relevant proceeding; (d) the manner in which the investments of any Portfolio are being managed; (e) a difference in voting instructions given by variable annuity contract and variable life insurance contract owners; or (f) a decision by an insurer to disregard the voting instructions of contract owners. The Trustee shall promptly inform the Company if they determine that an irreconcilable material conflict exists and the implication thereof.

4.2 The Company agrees to promptly report any potential or existing conflicts of which it is aware to the Trustees. The Company will assist the Trustees in carrying out their responsibilities under the Exemptive Order by providing the Trustees with all information reasonably necessary for the Trustees to consider any issues raised including, but not limited to, information as to a decision by the Company to disregard Contract owner voting instructions.

4.3 If it is determined by a majority of the Trustees, or a majority of its disinterested Trustees, that a material irreconcilable conflict exists that affects the interests of Contract owners, the Company shall, in cooperation with other Participating Insurance Companies whose contract owners are also affected, at its expense and to the extent reasonably practicable (as determined by the Trustees) take whatever steps are necessary to remedy or eliminate the irreconcilable material conflict, which steps could include: (a) withdrawing the assets allocable to some or all of the Accounts from the Trust or any Portfolio and reinvesting such assets in a different investment medium, including (but not limited to) another Portfolio of the Trust, or submitting the question of whether or not such segregation should be implemented to a vote of all affected Contract owners and, as appropriate, segregating the assets of any appropriate group (i.e., annuity contract owners, life insurance contract owners, or variable contract owners of one or more Participating Insurance Companies) that votes in favor of such segregation, or offering to the affected Contract owners the option of making such a change; and (b) establishing a new registered management investment company or managed separate account.

4.4 If a material irreconcilable conflict arises because of a decision by the Company to disregard Contract owner voting instructions and that decision represents a minority position or would preclude a majority vote, the Company may be required, at the Trust’s election, to

withdraw the affected Account’s investment in the Trust and terminate this Agreement with respect to such Account; provided, however that such withdrawal and termination shall be limited to the extent required by the foregoing material irreconcilable conflict as determined by a majority of the disinterested Trustees. Any such withdrawal and termination must take place within six (6) months after the Trust gives written notice that this provision is being implemented. Until the end of such six (6) month period, the Trust shall continue to accept and implement orders by the Company for the purchase and redemption of shares of the Trust.

4.5 If a material irreconcilable conflict arises because a particular state insurance regulator’s decision applicable to the Company conflicts with the majority of other state regulators, then the Company will withdraw the affected Account’s investment in the Trust and terminate this Agreement with respect to such Account within six (6) months after the Trustees inform the Company in writing that it has determined that such decision has created an irreconcilable material conflict; provided, however, that such withdrawal and termination shall be limited to the extent required by the foregoing material irreconcilable conflict as determined by a majority of the disinterested Trustees. Until the end of such six (6) month period, the Trust shall continue to accept and implement orders by the Company for the purchase and redemption of Shares of the Trust.

4.6 For purposes of Sections 4.3 through 4.6 of this Agreement, a majority of the disinterested Trustees shall determine whether any proposed action adequately remedies any irreconcilable material conflict, but in no event will the Company be required to establish a new funding medium for the Contracts if an offer to do so has been declined by vote of a majority of Contract owners materially adversely affected by the irreconcilable material conflict. In the event that the Trustees determine that any proposed action does not adequately remedy any irreconcilable material conflict, then the Company will withdraw the Account’s investment in the Trust and terminate this Agreement within six (6) months after the Trustees inform the Company in writing of the foregoing determination; provided, however, that such withdrawal and termination shall be limited to the extent required by any such material irreconcilable conflict as determined by a majority of the disinterested Trustees.

4.7 The Company shall at least annually submit to the Trustees such reports, materials or data as the Trustees may reasonably request so that the Trustees may fully carry out the duties imposed upon them by the Exemptive Order, and said reports, materials and data shall be submitted more frequently if deemed appropriate by the Trustees.

4.8 If and to the extent that Rule 6e-2 and Rule 6e-3(T) are amended, or Rule 6e-3 is adopted, to provide exemptive relief from any provision of the 1940 Act or the rules promulgated thereunder with respect to mixed or shared funding (as defined in the Exemptive Order) on terms and conditions materially different from those contained in the Exemptive Order, then the Trust and/or the Participating Insurance Companies, as appropriate, shall take such steps as may be necessary to comply with Rules 6e-2 and 6e-3(T), as amended, and Rule 6e-3, as adopted, to the extent such rules are applicable.
