IMPORTANT INFORMATION ABOUT THE AIM V.I. TOTAL RETURN FUND

Fund Termination and Liquidation. The Board of Trustees of AIM Variable Insurance Funds has decided to terminate and liquidate the AIM V.I. Total Return Fund (the "AIM Fund"). In order to effect such liquidation, the AIM Fund will be closed to new investors on or about December 21, 2005 (the "Closing Date"), and shareholders will receive the net asset value per share for all the shares they own on the Closing Date.

To prepare for the closing and liquidation of the AIM Fund, the AIM Fund's portfolio managers may need to increase the portion of the AIM Fund's assets held in cash and similar instruments in order to pay the fund's expenses and meet redemption requests. As a result, the AIM Fund's normal exposure to stock and bond investments will be reduced or eliminated prior to the Closing Date.

Important Information about the Fund Termination and Liquidation.

• Anytime prior to the Closing Date you may voluntarily transfer amounts that you have allocated to the subaccount which invests in the AIM Fund to any of the other available investment options. These investment options include the fixed account and the subaccounts of the variable account. See The Investment Options, page 18, of your policy prospectus for more information about these other investment options. See the Fund Expense Table, beginning on page 12, and Appendix B of your policy prospectus for summary information about the funds available through the variable account. There will be no charge for any such transfer, and any such transfer will not count as a transfer when imposing any applicable restriction or limit on transfers. See Transfers, page 45, of your policy prospectus.

After the Closing Date and our receipt of the proceeds from the liquidation of the AIM Fund, amounts which were allocated to the subaccount which invested in the AIM Fund will be automatically reallocated to the subaccount which invests in Class S shares of the ING Liquid Assets Portfolio. There will be no charge for this automatic reallocation, and this automatic reallocation will not count as a transfer when imposing any applicable restriction or limit on transfers. See Transfers, page 45, of your policy prospectus. Furthermore, you will not incur any tax liability because of this automatic reallocation, and your policy value immediately before the reallocation will equal your policy value immediately after the reallocation.

After the Closing Date, all future allocations directed to the subaccount which invested in the AIM Fund will be automatically allocated to the subaccount which invests in the ING Liquid Assets Portfolio.

After the Closing Date, the subaccount which invested in the AIM Fund will no longer be available through your policy.

If you have not already received a prospectus for the ING Liquid Assets Portfolio, it accompanies this supplement. Read this prospectus carefully before deciding what to do with amounts allocated to the AIM Fund.
