LARGE CAP BLEND ACCOUNT

Following is a summary of information about the Sentry Large Cap Blend Account. Investors are advised to learn key data about an investment prior to making any investment decision.

Objective

The objective of this account is to seek to earn long-term growth of capital. It is invested solely in the Vanguard® PRIMECAP Fund.

(The Large Cap Blend Account is available only to participants in retirement plans whose sponsors were Sentry customers on or before March 12, 2004. If this account is available to you, it will be included in your online enrollment and transfer forms.)

Investor Profile

The Large Cap Blend Account may be suitable for investors with very long-term investment horizons who are seeking long-term growth of capital. Individuals must be willing and able to accept substantial changes in unit price in the short, long and very long-term.

Investment Strategy

The Vanguard PRIMECAP Fund invests in stocks of companies with above-average prospects for continued earnings growth, strong industry positions, and skilled management teams. It may also invest in companies with below-average earnings but bright prospects for earnings growth. The advisor selects companies on the basis of fundamental factors, including current earnings, consistency, and quality of earnings in relationship to the market price of each company's stock. The fund will usually hold only a small percentage of assets in cash equivalents, although if the advisor believes that market conditions warrant a temporary defensive measure, the fund may hold cash investments without limit. The fund may not be broadly diversified; at times a large portion of assets may be invested in selected industries.

Investment Considerations

The Large Cap Blend Account uses an actively managed approach to investing in companies with large and mid-capitalizations. Portfolio turn-over has historically been very low. The Large Cap Blend Account can be used with other accounts to either increase or decrease potential returns and risks.
