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

Objective

The objective of this account is to earn long-term capital growth. It is invested solely in the T. Rowe Price Small-Cap Value Fund®.

The Small Cap Growth Account - I is available only to participants in retirement plans whose sponsors were Sentry customers on or before May 24, 2002. If this account is available in your plan, it will be included in your online enrollment and transfer forms.

Investor Profile

The Small Cap Growth Account - I may be suitable for investors with a very long-term investment horizon who are seeking long-term growth of capital by investing primarily in common stocks of small companies that are believed to be undervalued by the advisor. Individuals must be willing and able to accept substantial change in unit price in the short, long and very long term.

Investment Strategy

The fund seeks long-term capital growth by investing primarily in companies whose common stocks are believed to be undervalued. Reflecting a value approach to investing, the fund will seek the stocks of companies whose current stock prices do not appear to adequately reflect their underlying value as measured by assets, earnings, cash flow, or business franchises. Normally the fund will invest at least 80% of its total assets in the range of companies included in the Russell 2000 Index.

Investment Considerations

The Small Cap Growth Account - I takes an actively managed, value approach to investing in companies with small capitalizations. This account can be used by investors seeking to diversify a portion of their retirement planning account into the small cap market place with an active (as opposed to a passive/index) management strategy that follows a value approach with low turnover.
