To match the performance of the Standard & Poor's 500 Stock Index/(R)/. The
S&P 500 is made up of primarily large-capitalization companies that represent
a broad spectrum of the U.S. economy and about 70% of the U.S. stock market's
total capitalization. (Market capitalization is the number of a company's

<PAGE>
rily small- and mid-capitalization stocks (market capitalization under $1
billion and $1 billion to $5 billion, respectively). Market capitalization is
the number of a company's outstanding shares multiplied by the market price
per share. We use the Wilshire 4500 Equity Index to represent this universe.
Total Equity Market Index Fund
To match the performance of the entire U.S. stock market. We use the Wilshire
5000 Equity Index to represent the market as a whole. Because the largest
stocks carry the most weight in the index, large-capitalization stocks make
up a substantial majority of the Wilshire 5000's value.
2. What is each fund's principal investment strategy?
The Equity Index 500 Fund invests in all of the stocks in the S&P 500 Index.
We attempt to maintain holdings of each stock in proportion to its weight in
the index. This is known as a full replication strategy.
Standard & Poor's constructs the index by first identifying major industry
categories and then allocating a representative sample of the larger and more
liquid stocks in those industries to the index. S&P weights each stock
according to its total market value. The 50 largest companies in the index
currently account for over 50% of its value.
The Extended Equity Market Index Fund uses a sampling strategy, investing in
a group of stocks representative of the Wilshire 4500 Index. The fund does
not attempt to fully replicate the index by owning each of the stocks in it.
Despite its name, the Wilshire 4500 includes more than 6,500 stocks.
The Total Equity Market Index Fund uses a sampling strategy, investing in a
broad spectrum of small-, mid-, and large-capitalization stocks
representative of the Wilshire 5000 Index. The fund does not attempt to fully
replicate the index by owning each of the stocks in it. Despite its name, the
Wilshire 5000 includes more than 7,000 stocks.
In an attempt to recreate the Wilshire indices, we select stocks in terms of
industry, size, and other characteristics. For example, if technology stocks
made up 15% of the Wilshire index, the Extended Equity Market Index Fund
would invest about 15% of its assets in technology stocks with similar
characteristics. Several factors are considered in selecting representative
stocks, including historical price movement, market capitalization,
transaction costs, and others.
T. Rowe Price continually compares the composition of all three funds to that
of the indices. If a misweighting develops, the portfolios are rebalanced in
an effort to bring them into line with their respective indices. When
investing cash flow, the funds may purchase stocks, stock index futures, or
stock
<PAGE>
options. This approach is intended to minimize any deviations in performance.
All three funds intend to remain fully invested during all market conditions.

3. What are the main risks of investing in the funds?
Each fund is designed to track broad segments of the stock market--whether
they are rising or falling. Markets as a whole can decline for many reasons,
including adverse political or economic developments here or abroad, changes
in investor psychology, or heavy institutional selling.
Since each fund is passively managed and seeks to remain fully invested at
all times, assets cannot be shifted from one stock or group of stocks to
another based on their prospects, or from stocks into bonds or cash
equivalents in an attempt to cushion the impact of a market decline.
Therefore, actively managed funds may outperform these funds. In addition,
fund returns are likely to be slightly below those of the index because the
fund has fees and transaction expenses while indices have none. The timing of
cash flows and a fund's size can also influence returns. While there is no
guarantee, the investment manager expects the correlation between the fund
and the index to be at least .95. A correlation of 1.00 means the return of a
fund can be completely explained by the return of an index.
While there is no guarantee, Equity Index 500 Fund should tend to be less
volatile than the overall market because of its focus on larger-cap stocks.
However the fund emphasizes large-cap stocks, which may at times lag shares
<PAGE>
of smaller, faster-growing companies. The fund may also pay a modest dividend
that can help offset losses in falling markets.
The use of sampling for the Extended Equity and Total Equity Funds will
likely result in some deviation from their respective indices. In addition,
for all three index funds, returns are likely to be slightly below those of
the indices because the funds have fees and transaction expenses while
indices have none. The timing of cash flows and a fund's size can also
influence returns. While there is no guarantee, the investment manager
expects the correlation between the funds and their respective indices to be
at least .95. A correlation of 1.00 means the return of a fund can be
completely explained by the return of an index.
If each fund uses futures and options, it is exposed to additional volatility
and potential losses.
As with any mutual fund, there can be no guarantee the funds will achieve
their objectives.
. Each fund's share price may decline, so when you sell your shares, you may
lose money. An investment in each fund is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any
other government agency.
4. How can I tell which fund is most appropriate for me?
Consider your investment goals, your time horizon for achieving them, and
your tolerance for the inherent risk of common stock investments. If you seek
a relatively low-cost way of participating in the U.S. equity markets through
a passively managed portfolio, one or more of the funds could be an
appropriate part of your overall investment strategy. The fund or funds you
select should not represent your complete investment program or be used for
short-term trading purposes.
The segments of the stock market to which you want exposure and the degree of
volatility you can accept in pursuit of long-term capital gains can guide you
in choosing among the funds.
The S&P 500 Index is one of the most widely tracked stock indices in the
world. If you want to closely match the performance of the mostly large-cap
stocks in this index, with the same level of risk, the Equity Index 500 Fund
may be an appropriate choice.
If you seek potentially higher returns, can assume greater risk, and want
broad exposure to small- and mid-cap stocks, you may wish to invest in the
Extended Equity Market Index Fund.
<PAGE>
Finally, if your risk profile is between that of the first two funds and you
would like to participate in the entire U.S. stock market, you may want to
consider the Total Equity Market Index Fund.
Each fund can be used in both regular and tax-deferred accounts, such as
IRAs.
. Equity investors should have a long-term investment horizon and be willing
to wait out bear markets.
5. How has each fund performed in the past?
The bar charts and the average annual total return table indicate risk by
illustrating how much returns can differ from one year to the next. Each
fund's past performance is no guarantee of its future returns.
There is no bar chart information or performance table information for the
Extended Equity market Index Fund and Total Equity market Index Fund
because they did not have a full year of performance for 1998.

6. What fees or expenses will I pay?
The funds are 100% no load. However, the funds charge a redemption fee of
0.50%, payable to the funds, for shares held less than six months, and a
quarterly maintenance fee of $2.50 for accounts of less than $10,000. The fee
applies to exchanges as well. There are no other fees or charges to buy or
sell fund shares, reinvest dividends, or exchange into other T. Rowe Price
funds. There are no 12b-1 fees. The Extended Equity Market Index and Total
Equity Market Index Funds each have a single, all-inclusive fee covering
investment management and operating expenses. This will not fluctuate.

To limit the fund's expenses, T. Rowe Price contractually obligated itself to
waive its fees and bear any expenses through December 31, 1999, which would
cause the fund's ratio of expenses to average net assets to exceed 0.40%. The
fund previously operated under a 0.40% limitation that expired December 31,
1997. Fees waived or expenses paid or assumed under these agreements are
subject to reimbursement to T. Rowe Price by the fund whenever the fund's
expense ratio is below 0.40%; however, no reimbursement will be made after
December 31, 1999 (for the first agreement); or December 31, 2001 (for the
second agreement) or if it would result in the expense ratio exceeding 0.40%.
Any amounts reimbursed will have the effect of increasing fees otherwise paid
by the fund.
/c/ The management fee includes operating expenses.
Example. The following table gives you a rough idea of how expense ratios
may translate into dollars and helps you to compare the cost of investing in
these funds with that of other funds. Although your actual costs may be
higher or lower, the table shows how much you would pay if operating expenses
remain the same, the expense limitation currently in place is not renewed (if
applicable), you invest $10,000, you earn a 5% annual return, and you hold
the investment for the following periods:
