FUND PROFILE
___________, 1999
T. Rowe Price Index Trust
Extended Equity Market Index Fund
A fund that seeks to match the performance of the Wilshire 4500 Equity Index, a
broad index of small and mid-size common stocks.
This profile summarizes key information about the fund that is included in the
fund's prospectus. The fund's prospectus includes additional information about
the fund, including a more detailed description of the risks associated with
investing in the fund that you may want to consider before you invest. You may
obtain the prospectus and other information about the fund at no cost by
calling 1-XXX-XXX-XXXX, or by visiting our Web site at www.troweprice.com.
What is the fund's objective?
To match the performance of the U.S. stocks not included in the Standard &
Poor's 500 Stock Index/(R)/ (an index of large U.S. companies). These are
primarily 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.
The inclusion of a stock in the Wilshire index is in no way an endorsement by
Wilshire Associates of the stock as an investment, nor is Wilshire a sponsor
of the fund or in any way affiliated with it.
<PAGE>
What is the fund's principal investment strategy?
The 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.
In an attempt to recreate the Wilshire index, we select stocks in terms of
industry, size, and other characteristics. For example, if technology stocks
made up 15% of the Wilshire index, the 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 the fund to that of the
index. If a misweighting develops, the portfolio is rebalanced in an effort
to bring it into line with the index. When investing cash flow, the fund may
purchase stocks, stock index futures, or stock options. This approach is
intended to minimize any deviations in performance between the fund and
index.
The fund intends to remain fully invested during all market conditions. The
fund may sell securities primarily to rebalance its portfolio or satisfy
redemption requests.
Further information about the fund's investments, including a review of
market conditions and fund strategies and their impact on performance, is
available in the annual and semiannual shareholder reports. To obtain free
copies of any of these documents, call 1-XXX-XXX-XXXX.
What are the main risks of investing in the fund?
The 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 the 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 this fund. 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. Further, the use of sampling will
likely result in some deviation from the fund's index. While there is no
guarantee, the investment manager expects the correlation between the fund
and the index to be at least
<PAGE>
.95. A correlation of 1.00 means the return of a fund can be completely
explained by the return of an index.
The fund will be subject to the greater risks associated with small- and
mid-cap stocks. Smaller companies often have limited product lines, markets,
or financial resources, and may depend on a small group of inexperienced
managers. The securities of small companies may have limited marketability
and liquidity and are often subject to more abrupt or erratic market
movements than shares of larger companies or the major market averages. The
very nature of investing in smaller companies involves greater risk than is
customarily associated with large-cap companies.
If the 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 fund will achieve its
objective.
3 The fund's share price may decline, so when you sell your shares, you may
lose money. An investment in the 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.
How can I tell if the fund is appropriate for me?
Consider your investment goals, your time horizon for achieving them, and
your tolerance for risk. This fund provides a relatively low-cost way of
participating in the U.S. equity markets through a passively managed
portfolio. 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 fund. The fund should not represent your complete investment program
or be used for short-term trading purposes.
The fund can be used in both regular and tax-deferred accounts, such as IRAs.
3 Equity investors should have a long-term investment horizon and be willing
to wait out bear markets.
How has the fund performed in the past?
There is no bar chart information or performance table information for the
fund because it did not have a full year of performance for 1998.
What fees or expenses will I pay?
The fund is 100% no load. However, the fund charges a redemption fee of
0.50%, payable to the fund, for shares held less than six months, and a
quarterly mainte-
<PAGE>
nance fee of $2.50 for accounts of less than $10,000. 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 fund has a single,
all-inclusive fee covering investment management and operating expenses. This
will not fluctuate.

8 SIGN YOUR NEW ACCOUNT FORM
By signing this form, I certify that:
- - I agree to be bound by the terms of the prospectus for each fund in which
I am investing. If I am purchasing shares after reviewing a fund profile, I
understand that I will receive the prospectus after I purchase shares in the
fund. I have the authority and legal capacity to purchase mutual fund shares,
am of legal age in my state, and believe each investment is suitable for me.
- - I authorize T. Rowe Price, the Funds, their affiliates and agents to act on
any
instructions believed to be genuine for any service authorized on this form,
including telephone/computer services. The Funds use reasonable procedures
(including shareholder identity verification) to confirm that instructions
given by telephone/computer are genuine, and the Funds are not liable for
acting on these instructions. (If these procedures are not followed, it is the
opinion of certain regulatory agencies that the Funds may be liable for any
loss that may result from acting on instructions given.) I understand that
anyone who can properly identify my account(s) can make phone/computer
transactions on my behalf.
- - The Funds can redeem shares from my account(s) to reimburse a fund for
any loss due to nonpayment or other indebtedness.
<PAGE>
- - By selecting the electronic transfer service in Section 7C, I hereby authorize
T. Rowe Price to initiate credit and debit entries to my (our) account at the
Financial Institution indicated and for the Financial Institution to credit or
debit the same to such account through the Automated Clearing House
(ACH) system, subject to the rules of the Financial Institution, ACH, and the
Fund. T. Rowe Price may correct any transaction error with a debit or credit
to my Financial Institution account and/or Fund account. THIS AUTHORIZATION,
including any credit or debit entries initiated thereunder, is in full
force and effect until I notify T. Rowe Price of its revocation by telephone
or in writing and T. Rowe Price has had sufficient time to act on it.
- - Under penalties of perjury, the tax identification number(s) shown on
this form is correct. If I fail to give the correct number or fail to sign this
form, T. Rowe Price may reject, restrict, or redeem my investment. I may
also be subject to IRS backup withholding (currently 31%) on all
distributions and redemptions, and I may be subject to a $50 IRS penalty.
- - Under penalties of perjury, I am NOT subject to IRS backup withholding
because 1) I have not been notified, or 2) notification has been revoked
(cross out "NOT" if you are currently subject to withholding), or 3) I have
indicated in Section 4 that I am a nonresident alien and certify that for
dividends I am not a U.S. citizen or resident (or I am filing for a foreign
corporation, partnership, estate, or trust).
- - For clarification on any of these certification issues, please contact us for
assistance.
- - The IRS does not require your consent to any provision of this document
other than the certifications required to avoid backup withholding.
