This Supplement revises certain information with regard to the Short Term and Excessive Trading policies contained in the Prospectuses referenced above dated April 30, 2008.

The following replaces the third paragraph under “Short Term and Excessive Trading”:

Among the steps we have taken to reduce the frequency and effect of these practices are monitoring trading activity and imposing trading restrictions including the prohibition of more than twelve transfers among Divisions under a single Policy during a Policy year. Further, an investor who is identified as having made a transfer in and out of the same Division, excluding the Money Market Division, (“round trip transfer”) in an amount in excess of $10,000 within fourteen calendar days will be restricted from making additional transfers after the third such round trip transfer until the next Policy Anniversary date, and sent a letter informing him or her of the restriction. Thereafter, the same investor will be similarly restricted after the second such round trip transfer. An Owner who is identified as having made one or more round trip transfers within thirty calendar days aggregating more than one percent (1%) of the total assets of the Portfolio underlying a Division, excluding the Money Market Division, will be sent a warning letter after the first such round trip transfer and will be restricted from making additional transfers until the next Policy Anniversary date after the second such round trip transfer. Thereafter, the same investor will be similarly restricted after the first such round trip transfer. These limitations do not apply to automatic asset transfers, scheduled or systematic transactions involving portfolio rebalancing, dollar cost averaging, interest sweeps or to initial allocations or changes in allocations. Once a Policy is restricted, we will allow one additional transfer into the Money Market Division until the next Policy Anniversary. Policies such as yours (or other Policies supported by the Separate Account) may be purchased by a corporation or other entity as a means to informally finance the liabilities created by the entity’s employee benefit or similar plan. These Policies may be aggregately managed to match liabilities under such plans. Policies sold under these circumstances may be subject to special transfer restrictions. Namely, transactions involving portfolio rebalancing programs may be exempt from the twelve transfer per Policy year limitation where: (1) the purpose of the portfolio rebalancing program is to match the Policy to the entity’s employee benefit or similar plan; (2) the portfolio rebalancing program adequately protects against short-term or excessive trading; and (3) the portfolio rebalancing program is managed by a third party administrator that meets our requirements. We reserve the right to monitor or limit transactions involving portfolio rebalancing programs where we believe such transactions may be potentially harmful to a Portfolio.

Please read this Supplement carefully and keep it with your Prospectus for future reference.
