NOTICE OF UPCOMING FUND MERGERS

Effective on or about October 26, 2009 (the “Merger Effective Date”), the following Disappearing Funds will be reorganized and merge with and into the following Surviving Funds:

Disappearing Funds	Surviving Funds
ING LifeStyle Aggressive Growth Portfolio (Class I)	ING Retirement Growth Portfolio (Class I)
ING LifeStyle Growth Portfolio (Class I)
ING LifeStyle Moderate Growth Portfolio (Class I)	ING Retirement Moderate Growth Portfolio (Class I)
ING LifeStyle Moderate Portfolio (Class I)	ING Retirement Moderate Portfolio (Class I)

IMPORTANT INFORMATION REGARDING THE
UPCOMING FUND MERGERS

• Prior to the Merger Effective Date, you may transfer amounts allocated to a subaccount that invests in a Disappearing Fund to any other available subaccount or to the Fixed Account. See the “Transfers” section on beginning on page 43 of your policy prospectus for information about making subaccount transfers, including applicable restrictions and limits on transfers.
• On the Merger Effective Date, your investment in a subaccount that invests in a Disappearing Fund will automatically become an investment in the subaccount that invests in the corresponding Surviving Fund with an equal total net asset value. Unless you provide us with alternative allocation instructions, all future premiums received that would have been allocated to a subaccount corresponding to a Disappearing Fund will be automatically allocated to the subaccount corresponding to the applicable Surviving Fund. You may give us alternative allocation instructions by contacting our ING Customer Service Center at McCamish Systems, LLC, P.O. Box 724927, Atlanta, GA 30119, 1-866-790-1988.
  See the “Transfers” section beginning on page 43 of your policy prospectus for information about making fund allocation changes.
• After the Merger Effective Date, the Disappearing Funds will no longer exist and there will be no further disclosure regarding them in future supplements to the policy prospectus.
• You will not incur any fees or charges or any tax liability because of the mergers, and your policy value immediately before the mergers will equal your policy value immediately after the mergers.

IMPORTANT INFORMATION REGARDING THE
SURVIVING FUNDS

• The Surviving Funds will be available through your policy beginning on the Merger Effective Date.
• The Surviving Funds are structured as “fund of funds.” A fund structured as a “fund of fund” may have higher fees and expenses than a fund that invests directly in debt and equity securities because it also incurs the fees and expenses of the underlying funds in which it invests. Unlike the Disappearing Funds, which have historically invested primarily in actively managed funds, the Surviving Funds invest primarily in funds that are passively managed index funds. Please refer to the fund prospectus for information about the aggregate annual operating expenses of a Surviving Fund and its corresponding underlying fund or funds.
• The following chart lists each Surviving Fund’s investment adviser/subadviser and investment objective. More detailed information about the Surviving Funds can be found in the current prospectus for each Surviving Fund.
