7.1. The Board of Trustees of Rydex Variable Trust or Guggenheim Variable Funds Trust, as applicable (referred to in this Article VII collectively as the "Board"), will monitor the Funds for the existence of any material irreconcilable conflict between the interests of the contract owners of all separate accounts investing in the Funds. 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 Fund are being managed; (e) a difference in voting instructions given by Variable Insurance Product owners; or (f) a decision by a Participating Insurance Company to disregard the voting instructions of contract owners. The Board shall promptly inform the Company if it determines that an irreconcilable material conflict exists and the implications thereof.

7.2. The Company will report any potential or existing conflicts of which it is aware to the Board. The Company will assist the Board in carrying out its responsibilities under the Mixed and Shared Funding Exemptive Order, by providing the Board with all inforn1ation reasonably necessary for the Board to consider any issues raised. This includes, but is not limited to, an obligation by the Company to inform the Board whenever contract owner voting instructions are disregarded. Such responsibilities shall be carried out by the Company with a view only to the interests of its Contract owners.

7.3. If it is determined by a majority of the Board, or a majority of its disinterested n1embers, that a material irreconcilable conflict exists, the Company and other Participating Insurance Companies shall, at their expense and to the extent reasonably practicable and not in violation of applicable law (as determined by a majority of the disinterested directors), take whatever steps are necessary to remedy or eliminate the irreconcilable material conflict, up to and including: (1) withdrawing the assets allocable to some or all of the separate accounts from the Funds and reinvesting such assets in a different investment medium, including (but not limited to) another Series of the Funds, or submitting the question whether 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 policy 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 (2) establishing a new registered management investment company or managed separate account. Such responsibilities shall be carried out by the Company with a view only to the interests of its Contract owners. The Company will not be required to take any action addressed in this provision until it has obtained any regulatory approval that may be required.

7.4. 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 Funds' election, to withdraw the affected Account's investment in the Funds and terminate this Agreement with respect to such Account (at the Company's expense); 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 members of the Board. Any such withdrawal and. termination must take place within six (6) months after a Fund gives written notice that this provision is being implemented, and until the end of that six-month period the Distributor shall continue to accept and implement orders by the Company for the purchase (and redemption) of Fund shares, subject to the terms of the Fund's then-current prospectus.

7.5. If a material irreconcilable conflict arises because a particular state insurance regulator's decision applicable to the Company conflicts with the position of the majority of other state regulators., then the Company will withdraw the affected Account's investment in the Funds and terminate this Agreement with respect to such Account within six months after the Board informs 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 1nembers of the Board. Until the end of the foregoing six month period, the Underwriter and Funds shall continue to accept and implement orders by the Company for the purchase (and redemption) of shares of the Funds.

7.6. For purposes of Sections 7.3 through 7.6 of this Agreement, a majority of the disinterested members of the Board shall determine whether any proposed action adequately re1nedies any irreconcilable material conflict, but in no event will the Funds be required to establish a new funding medium for the Contracts. The Company shall not be required by Section 7.3 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 Board determines that any proposed action does not adequately remedy any irreconcilable material conflict, then the Company will withdraw the Account’s investment in a Fund (subject to any applicable regulatory approval) and terminate this Agreement within six (6) months after the Board informs 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 members of the Board.

7.7. If and to the extent the Mixed and Shared Funding Exemptive Order or any amendment thereto contains terms and conditions different from Sections 3.4, 3.5, 7.1, 7.2, 7.3, 7.4 and 7.5 of this Agreement, then the Funds and/or the Participating Insurance Companies, as appropriate, shall take such steps as may be necessary to comply with the Mixed and Shared Funding Exemptive Order, and Sections 3.4, 3.5, 7.1, 7.2, 7.3, 7.4 and 7.5 of this Agreement shall continue in effect only to the extent that terms and conditions substantially identical to such Sections are contained in the Mixed and Shared Funding Exemptive Order or any amendment thereto. 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 Mixed and Shared Funding Exemptive Order) on terms and conditions materially different from those contained in the Fixed and Shared Funding Exemptive Order, then (a) the Funds 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; and (b) Sections 3.4, 3.5, 7.1, 7.2, 7.3, 7.4, and 7.5 of this Agreement shall continue in effect only to the extent that terms and conditions substantially identical to such Sections are contained in such Rule(s) as so amended or adopted.
