 ABOUT THE FUNDS

 OBJECTIVE, STRATEGY, RISKS, AND EXPENSES
 ----------------------------------------------------------
   To help you decide whether these funds are appropriate for you, this section
   reviews their major characteristics.


 What is each fund's objective?

   Equity Index 500 Fund (formerly the Equity Index Fund)
   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 a substantial part of the U.S. stock
   market's total capitalization. (Market capitalization is the number of a
   company's outstanding shares multiplied by the market price per share.)

   Extended Equity Market Index Fund
   To match the performance of the U.S. stocks not included in the S&P 500.
   These are primarily small- and mid-capitalization stocks (market
   capitalization below the 1,000 largest companies in the U.S. stock market and
   between the 200 and 1,000 largest, respectively). We use the Wilshire 4500
   Completion 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 Total Market Index to represent the market as a whole. Because the
   largest stocks in the index carry the most weight, large-capitalization
   stocks make up a substantial majority of the Wilshire 5000's value.

   International Equity Index Fund

   To provide long-term capital growth. We use the FTSE Developed ex North
   America Index(TM), an equity market index based on the market capitalization
   of over 1,000 predominately large companies listed in about 20 countries,
   including Japan, the U.K., and developed countries in Continental Europe and
   the Pacific Rim.

   U.S. Bond Index Fund

   To match the total return performance of the U.S. investment-grade bond
   market. We use the Lehman Brothers U.S. Aggregate Index, which typically
   includes more than 5,000 fixed-income securities with an overall intermediate
   to long-range dollar-weighted average maturity. The range was 8.4 to 9.0
   years for the last five years ending December 31, 1999, although it will vary
   with market conditions.
<PAGE>


T. ROWE PRICE                                 2
   The inclusion of a stock or bond in the S&P 500 Index, the Wilshire, the
   FTSE(TM), or the Lehman Brothers indices is not an endorsement by Standard &
   Poor's, Wilshire Associates, FTSE, or Lehman Brothers of the stock or bond as
   an investment, nor are S&P, Wilshire, FTSE, and Lehman Brothers sponsors of
   the funds or in any way affiliated with them.


 What is each fund's principal investment strategy?

   The Equity Index 500 Fund invests substantially all of its assets 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. For example, the 50 largest companies in
   the index may account for over 50% of its value.


   The Extended Equity Market Index Fund uses a sampling strategy, investing
   substantially all of its assets 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 also uses a sampling strategy, investing
   substantially all of its assets in a broad spectrum of small-, mid-, and
   large-capitalization stocks representative of the Wilshire 5000 Index.

   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.

   The International Equity Index Fund will attempt to match the performance of
   the FTSE Developed ex North America Index by using a full replication
   strategy, investing substantially all of its assets in all of the stocks in
   the index. We attempt to own every stock in the index in proportion to its
   weight in the index. The index is constructed by selecting the countries it
   covers, sorting the market by industry groups, and targeting a significant
   portion of them for inclusion in the index.

   The U.S. Bond Index Fund also uses a sampling strategy, investing
   substantially all fund assets in bonds specifically represented in the Lehman
   Brothers U.S. Aggregate Index.  Under this approach, we will consider each
   broad segment of the benchmark - government bonds, mortgages, and corporate
   issues - and within
<PAGE>



ABOUT THE FUNDS                               3
   each segment select a set of U.S. dollar-denominated bonds that is
   representative of key benchmark traits. The most important of these traits
   are interest rate sensitivity, credit quality, and sector diversification,
   although other characteristics will be reflected.

   The fund's manager will invest substantially all fund assets in bonds
   specifically represented in the index. As a result, we expect to own U.S.
   government and agency obligations, mortgage- and asset-backed securities,
   corporate bonds, and U.S. dollar-denominated securities of foreign issuers.
   Other securities may also be purchased, such as collateralized mortgage
   obligations (CMOs) and certain types of derivatives, provided they have
   similar characteristics to index securities but potentially offer more
   attractive prices, yields, or liquidity. Derivatives, such as futures and
   options, will not exceed 10% of the fund's total assets. This flexibility in
   investing is intended to help the manager keep the fund's composition in line
   with the index and minimize deviations in performance between the fund and
   the index. 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 returns of the fund and the index move in the same
   direction (but not necessarily by the same amount). A correlation of 0.00
   means movements in the fund are unrelated to movements in the index.


   All funds except U.S. Bond Index

   T. Rowe Price continually compares the composition of all four 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 options (up to 10% of total assets for the International Equity Index
   Fund). This approach is intended to minimize any deviations in performance.

   Each fund may sell securities to better align its portfolio with the
   characteristics of its benchmark or satisfy redemption requests. However, the
   U.S. Bond Index is not required to sell specific bond issues that have been
   removed from the index.

  . For details about each fund's investment program, please see the Investment
   Policies and Practices section.


 What are the main risks of investing in the funds?

   Equity Index 500, Extended Equity Market Index, and Total Equity Market Index
   Funds

   Each fund is designed to track broad segments of the U.S. 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.

   While there is no guarantee, the Equity Index 500 Fund should tend to be less
   volatile than the other two portfolios because of its focus on larger-cap
   stocks. The fund emphasizes large-cap stocks, which may at times lag shares
   of smaller, faster-growing companies. It may also pay a modest dividend that
   can help offset losses in falling markets.

   The Extended Equity Market Index 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.


   While there is no guarantee, the Total Equity Market Index Fund is expected
   to have a risk level between the other two funds, and should have higher
   dividends than the Extended Equity Market Index Fund.

   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. Investments in futures and
   options are subject to additional volatility and potential losses.

   International Equity Index Fund
<PAGE>


ABOUT THE FUNDS                               5

   As with all stock funds, the fund's share price can fall because of weakness
   in one or more of its primary equity markets, a particular industry, or
   specific holdings. Stock markets can decline for many reasons, including
   adverse political or economic developments, changes in investor psychology,
   or heavy institutional selling. The prospects for an industry or company may
   deteriorate because of a variety of factors, including disappointing earnings
   or changes in the competitive environment.

   Funds that invest overseas generally carry more risk than funds that invest
   strictly in U.S. assets. Even investments in countries with highly developed
   economies are subject to significant risks. For example, Japanese stocks were
   in a steep decline for much of the 1990s. Some particular risks affecting
   this fund include the following:

  . Currency risk  This refers to a decline in the value of a foreign currency
   versus the U.S. dollar, which reduces the dollar value of securities
   denominated in that currency. The overall impact on a fund's holdings can be
   significant, unpredictable, and long-lasting depending on the currencies
   represented in the portfolio and how each one appreciates or depreciates in
   relation to the U.S. dollar. Under normal conditions, the fund does not
   expect to hedge its currency exposure.

  . Geographic risk  The economies and financial markets of various regions can
   be highly interdependent and may decline all at the same time.

  . Other risks of foreign investing  Risks can result from varying stages of
   economic and political development, differing regulatory environments,
   trading days, and accounting standards, and higher transaction costs of
   non-U.S. markets. Investments outside the United States could be subject to
   governmental actions such as capital or currency controls, nationalization of
   a company or industry, expropriation of assets, or high taxes that have an
   adverse effect on the fund.

  . While certain countries have made progress in economic growth,
   liberalization, fiscal discipline, and political and social stability, there
   is no assurance these trends will continue.

  . Tracking error  The fund's returns are likely to be below those of the index
   because the fund has fees and transaction costs while the index has none. The
   timing of cash flows and the fund's size can also influence returns. For
   example, the fund's failure to reach a certain asset size may limit its
   ability to purchase all the stocks in the index and achieve full replication.

  . Futures/options risk  To the extent the fund uses futures and options, it is
   exposed to additional volatility and potential losses.

   U.S. Bond Index Fund

   This fund is designed to track the performance of investment-grade bonds,
   regardless of whether they are rising or falling. In addition, index funds
   carry the same overall risks as the indices they are designed to track. The
   following are the principal risks the fund may face:

  . Interest rate risk  Investors should be concerned primarily with this risk
   because the Lehman Brothers U.S. Aggregate Index has typically had an
   intermediate to long weighted average maturity. An increase in interest rates
   will likely cause the fund's share price to fall, resulting in a loss of
   principal (see Table 4). That's because the bonds and fixed-income securities
   in the fund's portfolio become less attractive to other investors when
   securities with higher yields become available. Even GNMAs and other
   securities whose principal and interest payments are guaranteed by the U.S.
   government can decline in price if rates rise. The longer a bond's maturity,
   the greater its potential for price declines if rates rise and for price
   gains if rates fall. Therefore, this fund carries more interest rate risk
   than short-term bond funds.

  . Credit risk  This is the chance that any of a fund's holdings will have its
   credit rating downgraded or will default (fail to make scheduled interest or
   principal payments), potentially reducing the fund's income level and share
   price. While the fund's overall credit quality is investment grade (AAA to
   BBB), BBB securities are more susceptible to adverse economic conditions and
   some may have speculative characteristics.

  . The fund may continue to hold a security that has been downgraded or loses
   its investment-grade rating after purchase.


  . Prepayment risk and extension risk A mortgage-backed bond, unlike most other
   bonds, can be hurt when interest rates fall, because homeowners tend to
   refinance and prepay principal. The loss of high-yielding, underlying
   mortgages and the reinvestment of proceeds at lower interest rates can reduce
   the bond's potential price gain in response to falling interest rates, reduce
   the bond's yield, or even cause the bond's price to fall below what an
   investor paid for it, resulting in a capital loss. Any of these developments
   could cause a decrease in the fund's income, share price, or total return.


   Extension risk refers to a rise in interest rates that causes a fund's
   average maturity to lengthen unexpectedly due to a drop in mortgage
   prepayments. This would increase the fund's sensitivity to rising rates and
   its potential for price declines.


  . Derivatives risk  This is the potential that our investments in these
   complex and volatile instruments could affect the fund's share price. In
   addition to CMOs and better-known instruments such as futures, other
   derivatives that may be used in
<PAGE>



ABOUT THE FUNDS                               7
   limited fashion by the fund include interest-only (IO) and principal-only
   (PO) securities known as "strips." The value of these instruments is derived
   from an underlying pool of mortgage-backed securities or a CMO. All these
   instruments can be highly volatile, and their value can fall dramatically in
   response to rapid or unexpected changes in the mortgage or interest rate
   environment.


  . Tracking error  Differences between the composition of the fund and its
   index, as well as differences in pricing sources will likely result in
   tracking error, or the risk that fund performance will not match that of the
   index. Tracking error will also result because the fund incurs fees and
   expenses while indices have none. The timing of cash flows and the fund's
   size can also influence returns.

   All Funds

   Since each fund is passively managed and seeks to remain fully invested at
   all times, assets cannot be shifted from one stock or bond or group of stocks
   or bonds 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.

   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.


 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 bond, common stock, and international
   investments. The segments of the market to which you want exposure and the
   degree of volatility you can accept in pursuit of income or long-term capital
   gains can guide you in choosing among the funds. The fund or funds you select
   should not represent your complete investment program or be used for
   short-term trading purposes.

   If you seek a relatively low-cost way of participating in the U.S. equity
   markets through a passively managed portfolio, the Equity Index 500, Extended
   Equity Market Index, or Total Equity Market Index Funds could be an
   appropriate part of your overall investment strategy.

   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.
<PAGE>


T. ROWE PRICE                                 8
   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.


   If your risk profile is between that of the Equity Index 500 Fund and
   Extended Equity Market Index Fund, and you would like to participate in the
   entire U.S. stock market, you may want to consider the Total Equity Market
   Index Fund.

   If you want to diversify your domestic stock portfolio by adding exposure to
   an index of developed international stock markets, and can accept the risks
   that accompany foreign investments, the International Equity Index Fund could
   be an appropriate part of your overall investment strategy.

  . Equity investors should have a long-term investment horizon and be willing
   to wait out bear markets.


   If you seek a low-cost way to participate in the U.S. investment-grade bond
   market through a fund that tracks a well-known benchmark, the U.S. Bond Index
   Fund may be an appropriate investment.

   Each fund can be used in both regular and tax-deferred accounts, such as
   IRAs.


 How has each fund performed in the past?

   The bar charts showing calendar year returns and the average annual total
   return table indicate risk by illustrating how much returns can differ from
   one year to the next and over time for the Equity Index 500, Extended Equity
   Market Index, and Total Equity Market Index Funds. Because both the
   International Equity Index and U.S. Bond Index Funds commenced operations in
   2000, there is no historical performance information shown here. Performance
   history will be presented after the funds have been in operation for one
   calendar year. Fund past performance is no guarantee of future returns.

   The funds can also experience short-term performance swings, as shown by the
   best and worst calendar quarter returns during the years depicted in the
   charts.

 What fees or expenses will I pay?


   The funds are 100% no load. However, the Equity Index 500, Extended Equity
   Market Index, Total Equity Market Index, and U.S. Bond Index Funds charge a
   redemption fee of 0.50%, payable to the funds, on shares held less than six
   months. The International Equity Index Fund charges a redemption fee of 1%,
   payable to the fund, on shares held less than six months.

   The Extended Equity Market Index, Total Equity Market Index, International
   Equity Index, and U.S. Bond Index Funds each have a single, all-inclusive fee
   covering investment management and ordinary recurring operating expenses
   (other than fees and expenses for the funds' independent directors). These
   fees will not fluctuate. In contrast, most mutual funds have a fixed
   management fee plus a fee for operating expenses that varies according to a
   number of other factors.

   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. Redemption proceeds of less than $5,000 sent by wire are subject to a
   $5 fee paid to the fund.

   To limit the fund's expenses, T. Rowe Price contractually obligated itself to
   waive its fees and bear any expenses through December 31, 2000, which would
   cause the fund's ratio of expenses to average net assets to exceed 0.35%.
   Effective January 1, 2001, T. Rowe Price agreed to extend this expense
   limitation for a period of two years through December 31, 2002. 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 0.35%; however, no reimbursement will be made after December 31,
   2004, or if it would result in the expense ratio exceeding 0.35%. Any amounts
   reimbursed will have the effect of increasing fees otherwise paid by the

 OTHER INFORMATION ABOUT THE FUNDS
 ----------------------------------------------------------

 How does a stock or bond index mutual fund differ from the typical stock or
 bond mutual fund?


   Both types of index funds are passively managed, attempting to deviate as
   little as possible from a particular benchmark. Since fewer resources are
   devoted to researching stocks or bonds, and portfolio turnover (the buying
   and selling of securities) is low, an index fund incurs lower costs than the
   average equity or bond fund. The typical equity or bond fund is actively
   managed, meaning the manager makes purchase and sell decisions based on a
   particular security's prospects in pursuit of the fund's investment
   objective. In addition, index funds are almost entirely invested in stocks or
   bonds while actively managed funds often hold cash for strategic and
   defensive purposes.


 What specific markets are included in the FTSE Developed ex North America
 Index?

   International Equity Index Fund

   The countries in the index as of October 1, 2000, were: Australia, Austria,
   Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan,
   Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden,
   Switzerland, and United Kingdom.

   Countries may be removed or added to the index at any time. The index's
   performance reflects the reinvestment of all dividends and capital gains.


 What types of securities are included in the Lehman Brothers U.S. Aggregate
 Index?

   U.S. Bond Index Fund

   The index represents the U.S. investment-grade fixed-rate bond market, with
   components for government and corporate securities, mortgage pass-through
   securities, and asset-backed securities. To be included in the index, a
   security must be dollar-denominated; have at least one year to final
   maturity; have a $150 million par amount outstanding; and be rated investment
   grade by a major rating service.


 What are some of the funds' potential rewards?

   All Funds

  . Because the funds are passively managed, their expenses are lower than the
   average actively managed fund. Assuming all other factors are equal, lower
   expenses can increase a fund's total return.

  . Lower turnover should mean smaller capital gain distributions, which can
   raise a fund's after-tax returns.
<PAGE>


ABOUT THE FUNDS                               13

   All funds except U.S. Bond Index Fund

  . Stocks have historically been among the most rewarding investments, although
   past performance is no guarantee of future results. Each fund offers
   investors the opportunity to diversify their assets among many industries and
   individual stocks through a single investment.

  . Index investing provides investors with a convenient and relatively low-cost
   way to approximate the performance of either the entire stock market or a
   segment of it.

   International Equity Index Fund

  . Investing abroad increases the opportunities available to you. Some foreign
   countries may have greater potential for economic growth than the U.S.
   Foreign investments also provide effective diversification for an all-U.S.
   portfolio, since historically their returns have not moved in sync with U.S.
   stocks over long time periods. Investing a portion of your overall portfolio
   in foreign stock funds can enhance your diversification while providing the
   opportunity to boost long-term returns.

   Equity Index 500 and Total Equity Market Index Funds

  . Most of the stocks in the S&P 500 and many in the Wilshire 5000 pay a
   dividend, which, when reinvested, is an important capital building component.



 Is there other information I can review before making a decision?

   Investment Policies and Practices in Section 3 discusses various types of
   portfolio securities the funds may purchase as well as types of management
   practices the funds may use.


   You should also review the information in Section 2 that discusses contingent
   redemption fees and account maintenance fees.



 SOME BASICS OF FIXED INCOME INVESTING
 ----------------------------------------------------------

 U.S. Bond Index Fund


 Is a fund's yield fixed or will it vary?

   It will vary. The yield is calculated every day by dividing a fund's net
   income per share, expressed at annual rates, by the share price. Since both
   income and share price will fluctuate, a fund's yield will also vary.
   (Although money fund prices are stable, income is variable.)
<PAGE>


T. ROWE PRICE                                 14
 Is yield the same as total return?

   Not for bond funds. A fund's total return is the result of reinvested
   distributions from income and capital gains and the change in share price for
   a given period. Income is always a positive contributor to total return and
   can either enhance a rise in share price or help offset a price decline.


 What is credit quality and how does it affect yield?

   Credit quality refers to a bond issuer's expected ability to make all
   required interest and principal payments on time. Because highly rated
   issuers represent less risk, they can borrow at lower interest rates than
   less creditworthy issuers. Therefore, a fund investing in high-quality
   securities should have a lower yield than an otherwise comparable fund
   investing in lower-quality securities.


 What is meant by a bond fund's maturity?

   Every bond has a stated maturity date when the issuer must repay the bond's
   entire principal value to the investor. However, many bonds are "callable,"
   meaning their principal can be repaid earlier, on or after specified call
   dates. Bonds are most likely to be called when interest rates are falling
   because the issuer can refinance at a lower rate, just as a homeowner
   refinances a mortgage. In that environment, a bond's "effective maturity" is
   usually its nearest call date. For example, the rate at which homeowners pay
   down their mortgage principal determines the effective maturity of
   mortgage-backed bonds.

   A bond mutual fund has no real maturity, but it does have a weighted average
   maturity and a weighted average effective maturity. This number is an average
   of the stated or effective maturities of the underlying bonds, with each
   bond's maturity "weighted" by the percentage of fund assets it represents.
   Some funds target effective maturities rather than stated maturities when
   computing the average. This provides additional flexibility in portfolio
   management.


 What is meant by a bond fund's duration?

   Duration is a calculation that seeks to measure the price sensitivity of a
   bond or a bond fund to changes in interest rates. It is expressed in years,
   like maturity, but it is a better indicator of price sensitivity than
   maturity because it takes into account the time value of cash flows generated
   over the bond's life. Future interest and principal payments are discounted
   to reflect their present value and then are multiplied by the number of years
   they will be received to produce a value expressed in years - the duration.
   "Effective" duration takes into account call features and sinking fund
   payments that may shorten a bond's life.
<PAGE>


ABOUT THE FUNDS                               15
   Since duration can also be computed for bond funds, you can estimate the
   effect of interest rates on share price by multiplying fund duration by an
   expected change in interest rates. For example, the price of a bond fund with
   a duration of five years would be expected to fall approximately 5% if rates
   rose by one percentage point. (T. Rowe Price shareholder reports show
   duration.)


 How is a bond's price affected by changes in interest rates?

   When interest rates rise, a bond's price usually falls, and vice versa. In
   general, the longer a bond's maturity, the greater the price increase or
   decrease in response to a given change in rates, as shown in Table 4.

 ABOUT YOUR ACCOUNT
 PRICING SHARES AND RECEIVING SALE PROCEEDS
 ----------------------------------------------------------
   Here are some procedures you should know when investing in a T. Rowe Price
   fund.


 How and when shares are priced

   The share price (also called "net asset value" or NAV per share) for the
   funds is calculated at the close of the New York Stock Exchange, normally 4
   p.m. ET, each day the New York Stock Exchange is open for business. To
   calculate the NAV, the fund's assets are valued and totaled, liabilities are
   subtracted, and the balance, called net assets, is divided by the number of
   shares outstanding. Current market values are used to price fund shares.

   International Equity Index Fund

   The fund's portfolio securities usually are valued on the basis of the most
   recent closing market prices at 4 p.m. ET when the fund calculates its NAV.
   Most of the securities in which the fund invests, however, are traded in
   markets that close before that time. For securities primarily traded in the
   Far East, for example, the most recent closing prices may be as much as 15
   hours old at 4 p.m. Normally, developments that could affect the values of
   portfolio securities that occur between the close of the foreign market and 4
   p.m. ET will not be reflected in the fund's NAV. However, if the fund
   determines that such developments are so significant that they will, in its
   judgment, clearly and materially affect the value of the fund's securities,
   the fund may adjust the previous closing prices to reflect what it believes
   to be the fair value of the securities as of 4 p.m. ET. The fund may fair
   value securities in other situations, for example, when a particular foreign
   market is closed but the fund is open.

  . The various ways you can buy, sell, and exchange shares are explained at the
   end of this prospectus and on the New Account Form. These procedures may
   differ for institutional and employer-sponsored retirement accounts.


 How your purchase, sale, or exchange price is determined

   If we receive your request in correct form by 4 p.m. ET, your transaction
   will be priced at that day's NAV. If we receive it after 4 p.m., it will be
   priced at the next business day's NAV.

   We cannot accept orders that request a particular day or price for your
   transaction or any other special conditions.
<PAGE>


ABOUT THE FUNDS                               17
   Fund shares may be purchased through various third-party intermediaries
   including banks, brokers, and investment advisers. Where authorized by a
   fund, orders will be priced at the NAV next computed after receipt by the
   intermediary. Consult your intermediary to determine when your orders will be
   priced. The intermediary may charge a fee for its services.

   Note: The time at which transactions and shares are priced and the time until
   which orders are accepted may be changed in case of an emergency or if the
   New York Stock Exchange closes at a time other than 4 p.m. ET.


 How you can receive the proceeds from a sale

  . When filling out the New Account Form, you may wish to give yourself the
   widest range of options for receiving proceeds from a sale.

   If your request is received by 4 p.m. ET in correct form, proceeds are
   usually sent on the next business day. Proceeds can be sent to you by mail or
   to your bank account by Automated Clearing House (ACH) transfer or bank wire.
   ACH is an automated method of initiating payments from, and receiving
   payments in, your financial institution account. The ACH system is supported
   by over 20,000 banks, savings banks, and credit unions. Proceeds sent by ACH
   transfer should be credited the second business day after the sale. Proceeds
   sent by bank wire should be credited to your account the first business day
   after the sale.

  . Exception:  Under certain circumstances and when deemed to be in a fund's
   best interest, your proceeds may not be sent for up to seven calendar days
   after we receive your redemption request.

  . If for some reason we cannot accept your request to sell shares, we will
   contact you.

   Contingent Redemption Fee

   These funds can experience substantial price fluctuations and are intended
   for long-term investors. Short-term "market timers" who engage in frequent
   purchases and redemptions can disrupt the funds' investment programs and
   create additional transaction costs that are borne by all shareholders. For
   these reasons, the funds assess a 0.50% (1% for International Equity Index
   Fund) fee on redemptions (including exchanges) of fund shares held for less
   than six months.

   Redemption fees are paid to the funds to help offset transaction costs and to
   protect the funds' long-term shareholders. The funds will use the "first-in,
   first-out" (FIFO) method to determine the six-months holding period. Under
   this method, the date of the redemption or exchange will be compared with the
   earliest purchase date of shares held in the account. If this holding period
   is less than six months, the fee will be charged.
<PAGE>


T. ROWE PRICE                                 18
   The fee does not apply to any shares purchased through reinvested
   distributions (dividends and capital gains), shares held in retirement plans,
   such as 401(k), 403(b), 457, Keogh, profit sharing, SIMPLE IRA, SEP-IRA, and
   money purchase pension accounts, or to shares redeemed through designated
   systematic withdrawal plans. The fee does apply to shares held in other IRA
   accounts and to shares purchased through automatic investment plans
   (described under Shareholder Services). The fee may apply to shares in
   retirement plans held in broker omnibus accounts.


   In determining "six months," the funds will use the anniversary date of a
   transaction. Thus, shares purchased on January 1, 2001, for example, will be
   subject to the fee if they are redeemed on or prior to June 30, 2001. If they
   are redeemed on or after July 1, 2001, they will not be subject to the fee.




 USEFUL INFORMATION ON DISTRIBUTIONS AND TAXES
 ----------------------------------------------------------
  . All net investment income and realized capital gains are distributed to
   shareholders.


 Dividends and Other Distributions

   Dividend and capital gain distributions are reinvested in additional fund
   shares in your account unless you select another option on your New Account
   Form. The advantage of reinvesting distributions arises from compounding;
   that is, you receive income dividends and capital gain distributions on a
   rising number of shares.

   Distributions not reinvested are paid by check or transmitted to your bank
   account via ACH. If the Post Office cannot deliver your check, or if your
   check remains uncashed for six months, the fund reserves the right to
   reinvest your distribution check in your account at the NAV on the day of the
   reinvestment and to reinvest all subsequent distributions in shares of the
   fund. No interest will accrue on amounts represented by uncashed distribution
   or redemption checks.

   Income dividends

   U.S. Bond Index Fund

  . The U.S. Bond Index Fund declares income dividends daily at 4 p.m. ET to
   shareholders of record at that time provided payment has been received on the
   previous business day.

  . Dividends are ordinarily paid on the first business day of each month.

  . Fund shares will earn dividends through the date of redemption; also, shares
   redeemed on a Friday or prior to a holiday will continue to earn dividends
   until the next business day. Generally, if you redeem all of your shares at
   any time
<PAGE>



ABOUT THE FUNDS                               19
   during the month, you will also receive all dividends earned through the date
   of redemption in the same check. When you redeem only a portion of your
   shares, all dividends accrued on those shares will be reinvested, or paid in
   cash, on the next dividend payment date.


   Equity Index 500, Extended Market Index, and Total Market Index Funds

  . The Equity Index 500 Fund declares and pays dividends (if any) quarterly.


  . The Extended Market Index, and Total Market Index Funds declare and pay
   dividends (if any) annually.

  . A portion of fund dividends may be eligible for the 70% deduction for
   dividends received by corporations.


   International Equity Index Fund

  . The fund declares and pays dividends (if any) annually.

  . The dividends of the fund will not be eligible for the 70% deduction for
   dividends received by corporations, if, as expected, none of the fund's
   income consists of dividends paid by U.S. corporations.

   All Funds

   Capital gains
  . A capital gain or loss is the difference between the purchase and sale price
   of a security.

  . If a fund has net capital gains for the year (after subtracting any capital
   losses), they are usually declared and paid in December to shareholders of
   record on a specified date that month. If a second distribution is necessary,
   it is usually declared and paid during the first quarter of the following
   year.


 Tax Information

  . You will be sent timely information for your tax filing needs.

   You need to be aware of the possible tax consequences when:

  . You sell fund shares, including an exchange from one fund to another.


  . A fund makes a distribution to your account.

   Taxes on fund redemptions
   When you sell shares in any fund, you may realize a gain or loss. An exchange
   from one fund to another is still a sale for tax purposes.


   In January, you will be sent Form 1099-B indicating the date and amount of
   each sale you made in the fund during the prior year. This information will
   also be reported to the IRS. For most new accounts or those opened by
   exchange in 1984
<PAGE>



T. ROWE PRICE                                 20
   or later, we will provide the gain or loss on the shares you sold during the
   year, based on the "average cost," single category method. This information
   is not reported to the IRS, and you do not have to use it. You may calculate
   the cost basis using other methods acceptable to the IRS, such as "specific
   identification."

   To help you maintain accurate records, we send you a confirmation immediately
   following each transaction you make (except for systematic purchases and
   redemptions) and a year-end statement detailing all your transactions in each
   fund account during the year.

   Taxes on fund distributions
   All Funds

   In January, you will be sent Form 1099-DIV indicating the tax status of any
   dividend and capital gain distributions made to you. This information will
   also be reported to the IRS. Distributions are generally taxable to you for
   the year in which they were paid. You will be sent any additional information
   you need to determine your taxes on fund distributions, such as the portion
   of your dividends, if any, that may be exempt from state income taxes.


   The tax treatment of a capital gain distribution is determined by how long
   the fund held the portfolio securities, not how long you held shares in the
   fund. Short-term (one year or less) capital gain distributions are taxable at
   the same rate as ordinary income and long-term gains on securities held more
   than 12 months are taxed at a maximum rate of 20%. If you realized a loss on
   the sale or exchange of fund shares that you held six months or less, your
   short-term loss must be reclassified to a long-term loss to the extent of any
   long-term capital gain distribution received during the period you held the
   shares.

   International Equity Index Fund

   Distributions resulting from the sale of certain foreign currencies and debt
   securities, to the extent of foreign exchange gains, are taxed as ordinary
   income or loss. If the fund pays nonrefundable taxes to foreign governments
   during the year, the taxes will reduce the fund's dividends but will still be
   included in your taxable income. However, you may be able to claim an
   offsetting credit or deduction on your tax return for your portion of foreign
   taxes paid by the fund.

  . Distributions are taxable whether reinvested in additional shares or
   received in cash.

   Tax effect of buying shares before a capital gain or dividend distribution
   If you buy shares shortly before or on the "record date" -  the date that
   establishes you as the person to receive the upcoming distribution - you will
   receive a portion of the money you just invested in the form of a taxable
   distribution. There-
<PAGE>


ABOUT THE FUNDS                               21
   fore, you may wish to find out a fund's record date before investing. Of
   course, a fund's share price may, at any time, reflect undistributed capital
   gains or income and unrealized appreciation, which may result in future
   taxable distributions.


  . The preceding tax information summary does not apply to retirement accounts,
   such as IRAs, which are not subject to current tax.



 TRANSACTION PROCEDURES AND SPECIAL REQUIREMENTS
 ----------------------------------------------------------
  . Following these procedures helps assure timely and accurate transactions.


 Purchase Conditions

   Nonpayment

   If you pay with a check or ACH transfer that does not clear or if your
   payment is not timely received, your purchase will be canceled. You will be
   responsible for any losses or expenses incurred by each fund or transfer
   agent, and the fund can redeem shares you own in this or another identically
   registered T. Rowe Price account as reimbursement. Each fund and its agents
   have the right to reject or cancel any purchase, exchange, or redemption due
   to nonpayment.

   U.S. dollars; type of check
   All purchases must be paid for in U.S. dollars; checks must be drawn on U.S.
   banks.


 Sale (Redemption) Conditions

   Holds on immediate redemptions: 10-day hold

   If you sell shares that you just purchased and paid for by check or ACH
   transfer, the funds will process your redemption but will generally delay
   sending you the proceeds for up to 10 calendar days to allow the check or
   transfer to clear. (The 10-day hold does not apply to purchases paid for by
   bank wire or automatic purchases through your paycheck.)

   Telephone, Tele*Access/(R)/, and personal computer transactions
   Exchange and redemption services through telephone and Tele*Access are
   established automatically when you sign the New Account Form unless you check
   the boxes that state you do not want these services. Personal computer
   transactions must be authorized separately. T. Rowe Price funds and their
   agents use reasonable procedures to verify the identity of the shareholder.
   If these procedures are followed, the funds and their agents are not liable
   for any losses that may occur from acting on unauthorized instructions. A
   confirmation is sent promptly after a transaction. Please review it carefully
   and contact T. Rowe Price immediately about any transaction you believe to be
   unauthorized. All telephone conversations are recorded.
<PAGE>


T. ROWE PRICE                                 22
   Redemptions over $250,000
   Large sales can adversely affect a portfolio manager's ability to implement a
   fund's investment strategy by causing the premature sale of securities that
   would otherwise be held. If, in any 90-day period, you redeem (sell) more
   than $250,000, or your sale amounts to more than 1% of fund net assets, the
   fund has the right to pay the difference between the redemption amount and
   the lesser of the two previously mentioned figures with securities from the
   fund.


 Excessive Trading

  . T. Rowe Price may bar excessive traders from purchasing shares.


   Frequent trades in your account or accounts controlled by you can disrupt
   management of a fund and raise its expenses. To deter such activity, the
   funds have adopted an excessive trading policy. If you violate our excessive
   trading policy, you may be barred indefinitely and without further notice
   from further purchases of T. Rowe Price funds.

  . Trades placed directly with T. Rowe Price  If you trade directly with T.
   Rowe Price, you can make one purchase and one sale involving the same fund
   within any 120-day period. For example, if you are in fund A, you can move
   assets from fund A to fund B and, within the next 120 days, sell your shares
   in fund B to return to fund A or move to fund C. If you exceed this limit, or
   if your trade activity involves market timing, you are in violation of our
   excessive trading policy.

   Two types of transactions are exempt from this policy: 1) trades solely in
   money market funds (exchanges between a money fund and a nonmoney fund are
   not exempt); and 2) systematic purchases and redemptions (see Information
   About Your Services).


  . Trades placed through intermediaries  If you purchase fund shares through an
   intermediary including a broker, bank, investment adviser, or other third
   party, you can make one purchase and one sale involving the same fund within
   any 120-day period. If you exceed this limit or if you hold fund shares for
   less than 60 calendar days, you are in violation of our excessive trading
   policy. Systematic purchases and redemptions are exempt from this policy.


 Keeping Your Account Open

   Due to the relatively high cost to a fund of maintaining small accounts, we
   ask you to maintain an account balance of at least $1,000. If your balance is
   below $1,000 for three months or longer, we have the right to close your
   account after giving you 60 days in which to increase your balance.
<PAGE>


ABOUT THE FUNDS                               23
 Account Maintenance Fee


   The account maintenance fee, paid to the fund, is charged on a quarterly
   basis usually during the last week of a calendar quarter. On the day of the
   assessment, accounts with balances below $10,000 will be charged the fee.
   Please note that the fee will be charged to accounts that fall below $10,000
   due to market fluctuations, redemptions or exchanges. When an account with
   less than $10,000 is closed either through redemption or exchange, the fee
   will be charged and deducted from the proceeds. The fee will apply to IRA
   accounts. The fee does not apply to retirement plans directly registered with
   T. Rowe Price Services, or accounts maintained by intermediaries through
   NSCC/(R)/ Networking.


 Signature Guarantees

  . A signature guarantee is designed to protect you and the T. Rowe Price funds
   from fraud by verifying your signature.

   You may need to have your signature guaranteed in certain situations, such
   as:

  . Written requests 1) to redeem over $100,000, or 2) to wire redemption
   proceeds.

  . Remitting redemption proceeds to any person, address, or bank account not on
   record.

  . Transferring redemption proceeds to a T. Rowe Price fund account with a
   different registration (name or ownership) from yours.

  . Establishing certain services after the account is opened.

   You can obtain a signature guarantee from most banks, savings institutions,
   broker-dealers, and other guarantors acceptable to T. Rowe Price. We cannot
   accept guarantees from notaries public or organizations that do not provide
   reimbursement in the case of fraud.

 MORE ABOUT THE FUNDS
 ORGANIZATION AND MANAGEMENT
 ----------------------------------------------------------

 How are the funds organized?

   T. Rowe Price Index Trust, Inc. was incorporated in Maryland in 1989. It
   consists of three series and each is an open-end investment company, or
   mutual fund.  The Equity Index 500 Fund was established in 1990, and the
   Extended Equity Market Index and Total Equity Market Index Funds were
   established in 1997.  The Equity Index 500 Fund was originally established as
   the Equity Index Fund but changed its name effective January 30, 1998. The
   International Equity Index and the U.S. Bond Index Funds were incorporated in
   Maryland in 2000 as open-end investment companies. Mutual funds pool money
   received from shareholders and invest it to try to achieve specified
   objectives.

  . Shareholders benefit from T. Rowe Price's 63 years of investment management
   experience.


 What is meant by "shares"?

   As with all mutual funds, investors purchase shares when they put money in a
   fund. These shares are part of a fund's authorized capital stock, but share
   certificates are not issued.

   Each share and fractional share entitles the shareholder to:

  . Receive a proportional interest in a fund's income and capital gain
   distributions.

  . Cast one vote per share on certain fund matters, including the election of
   fund directors, changes in fundamental policies, or approval of changes in
   the fund's management contract.


 Do T. Rowe Price funds have annual shareholder meetings?

   The funds are not required to hold annual meetings and, to avoid unnecessary
   costs to fund shareholders, do not do so except when certain matters, such as
   a change in fundamental policies, must be decided. In addition, shareholders
   representing at least 10% of all eligible votes may call a special meeting,
   if they wish, for the purpose of voting on the removal of any fund director
   or trustee. If a meeting is held and you cannot attend, you can vote by
   proxy. Before the meeting, the fund will send you proxy materials that
   explain the issues to be decided and include instructions on voting by mail
   or telephone, or on the Internet.

   taxes, brokerage, non-recurring and extraordinary items or fees and expenses
   for the funds' independent directors.



 UNDERSTANDING PERFORMANCE INFORMATION
 ----------------------------------------------------------
   This section should help you understand the terms used to describe fund
   performance. You will come across them in shareholder reports you receive
   from us; in our newsletter, The Price Report; in T. Rowe Price
   advertisements; and in the media.


 Total Return

   This tells you how much an investment has changed in value over a given time
   period. It reflects any net increase or decrease in the share price and
   assumes that all dividends and capital gains (if any) paid during the period
   were reinvested in additional shares. Therefore, total return numbers include
   the effect of compounding.
<PAGE>


ABOUT THE FUNDS                               27
   Advertisements may include cumulative or average annual total return figures,
   which may be compared with various indices, other performance measures, or
   other mutual funds.


 Cumulative Total Return

   This is the actual return of an investment for a specified period. A
   cumulative return does not indicate how much the value of the investment may
   have fluctuated during the period. For example, an investment could have a
   10-year positive cumulative return despite experiencing some negative years
   during that time.


 Average Annual Total Return

   This is always hypothetical and should not be confused with actual
   year-by-year results. It smooths out all the variations in annual performance
   to tell you what constant year-by-year return would have produced the
   investment's actual cumulative return. This gives you an idea of an
   investment's annual contribution to your portfolio, provided you held it for
   the entire period.


 Yield

   The current or "dividend" yield on a fund or any investment tells you the
   relationship between the investment's current level of annual income and its
   price on a particular day. The dividend yield reflects the actual income paid
   to shareholders for a given period, annualized, and divided by the price at
   the end of the period. For example, a fund providing $5 of annual income per
   share and a price of $50 has a current yield of 10%. Yields can be calculated
   for any time period.

   The advertised or SEC yield is found by determining the net income per share
   (as defined by the Securities and Exchange Commission) earned by a fund
   during a 30-day base period and dividing this amount by the per share price
   on the last day of the base period. The SEC yield-also called the
   standardized yield-may differ from the dividend yield.



 INVESTMENT POLICIES AND PRACTICES
 ----------------------------------------------------------

   This section takes a detailed look at some of the types of fund securities
   and the various kinds of investment practices that may be used in day-to-day
   portfolio management. Fund investments are subject to further restrictions
   and risks described in the Statement of Additional Information.

   Shareholder approval is required to substantively change fund objectives and
   certain investment restrictions noted in the following section as
   "fundamental policies." The managers also follow certain "operating policies"
   which can be
<PAGE>



T. ROWE PRICE                                 28
   changed without shareholder approval. However, significant changes are
   discussed with shareholders in fund reports. Fund investment restrictions and
   policies are adhered to at the time of investment. A later change in
   circumstances will not require the sale of an investment if it was proper at
   the time it was made.


   Changes in fund holdings, fund performance, and the contribution of various
   investments are discussed in the shareholder reports sent to you.

  . Fund managers have considerable leeway in choosing investment strategies and
   selecting securities they believe will help achieve fund objectives.


 Types of Portfolio Securities


   All Funds

   In seeking to meet their investment objectives, each fund may invest in any
   type of security or instrument (including certain potentially high-risk
   derivatives described in this section) whose investment characteristics are
   consistent with the fund's investment program. The following pages describe
   various types of fund securities and investment management practices.

   Fundamental policy  Each fund will not purchase a security if, as a result,
   with respect to 75% of its total assets, more than 5% of its total assets
   would be invested in securities of a single issuer, or if more than 10% of
   the outstanding voting securities of the issuer would be held by the funds.
   These limitations do not apply to the purchase of securities issued or
   guaranteed by the U.S. government, its agencies, or instrumentalities.

   All Funds except U.S. Bond Index

   Hybrid Instruments

   These instruments (a type of potentially high-risk derivative) can combine
   the characteristics of securities, futures, and options. For example, the
   principal amount, redemption, or conversion terms of a security could be
   related to the market price of some commodity, currency, or securities index.
   Such securities may earn interest or pay dividends at below market or even
   relatively nominal rates. Under some conditions, the redemption value of such
   an investment could be zero.

  . Hybrids have volatile prices and limited liquidity, and their use may not be
   successful.

   Operating policy  Fund investments in hybrid instruments are limited to 10%
   of total assets.
<PAGE>


ABOUT THE FUNDS                               29

   International Equity Index Fund

   The fund must invest at least 80% of its total assets in securities that make
   up the FTSE Developed ex North America Index.

   Fundamental policy  The fund will not invest more than 25% of its total
   assets (concentrate) in any single industry except to the extent the index
   concentrates in that industry.


   U.S. Bond Index Fund The fund must invest at least 80% of its total assets in
   securities that comprise the Lehman Brothers U.S. Aggregate Index. Bonds
   purchased by the fund that are removed from the index will not be counted as
   part of the 80% requirement.

   Fundamental policy  The fund will not invest more than 25% of its total
   assets (concentrate) in any single industry except to the extent the index
   concentrates in that particular industry.


   Bonds
   A bond is an interest-bearing security -  an IOU - issued by companies or
   governmental units. The issuer has a contractual obligation to pay interest
   at a stated rate on specific dates and to repay principal (the bond's face
   value) on a specified date. An issuer may have the right to redeem or "call"
   a bond before maturity, and the investor may have to reinvest the proceeds at
   lower market rates.

   A bond's annual interest income, set by its coupon rate, is usually fixed for
   the life of the bond. Its yield (income as a percent of current price) will
   fluctuate to reflect changes in interest rate levels. A bond's price usually
   rises when interest rates fall, and vice versa, so its yield stays consistent
   with current market conditions.

   Bonds may be unsecured (backed by the issuer's general creditworthiness only)
   or secured (also backed by specified collateral).

   Certain bonds have interest rates that are adjusted periodically. These
   interest rate adjustments tend to minimize fluctuations in the bonds'
   principal values. The maturity of those securities may be shortened under
   certain specified conditions.

   Bonds may be designated as senior or subordinated obligations. Senior
   obligations generally have the first claim on a corporation's earnings and
   assets and, in the event of liquidation, are paid before subordinated debt.

   Foreign Securities
   Investments may be made in U.S. dollar-denominated foreign securities. Such
   investments increase a portfolio's diversification and may enhance return,
   but they also involve some special risks such as exposure to potentially
   adverse local political and economic developments; nationalization and
   exchange controls;
<PAGE>


T. ROWE PRICE                                 30
   potentially lower liquidity and higher volatility; possible problems arising
   from accounting and disclosure, settlement, and regulatory practices that
   differ from U.S. standards.

   Asset-Backed Securities
   An underlying pool of assets, such as credit card or automobile trade
   receivables or corporate loans or bonds, backs these bonds and provides the
   interest and principal payments to investors. Credit quality depends
   primarily on the quality of the underlying assets and the level of credit
   support, if any, provided by the issuer. The underlying assets (i.e., loans)
   are sometimes subject to prepayments which can shorten the security's
   weighted average life and may lower its return. The value of these securities
   also may change because of actual or perceived changes in the
   creditworthiness of the originator, servicing agent, or of the financial
   institution providing the credit support.

   Mortgage-Backed Securities
   The fund may invest in a variety of mortgage-backed securities. Mortgage
   lenders pool individual home mortgages with similar characteristics to back a
   certificate or bond, which is sold to investors such as the fund. Interest
   and principal payments generated by the underlying mortgages are passed
   through to the investors. The "big three" issuers are the Government National
   Mortgage Association (GNMA), the Federal National Mortgage Association
   (Fannie Mae), and the Federal Home Loan Mortgage Corporation (Freddie Mac).
   GNMA certificates are backed by the full faith and credit of the U.S.
   government, while others, such as Fannie Mae and Freddie Mac certificates,
   are only supported by the ability to borrow from the U.S. Treasury or
   supported only by the credit of the agency. Private mortgage bankers and
   other institutions also issue mortgage-backed securities.

   Mortgage-backed securities are subject to scheduled and unscheduled principal
   payments as homeowners pay down or prepay their mortgages. As these payments
   are received, they must be reinvested when interest rates may be higher or
   lower than on the original mortgage security. Therefore, these securities are
   not an effective means of locking in long-term interest rates. In addition,
   when interest rates fall, the pace of mortgage prepayments picks up. These
   refinanced mortgages are paid off at face value (par), causing a loss for any
   investor who may have purchased the security at a price above par. In such an
   environment, this risk limits the potential price appreciation of these
   securities and can negatively affect the fund's net asset value. When rates
   rise, the prices of mortgage-backed securities can be expected to decline,
   although historically these securities have experienced smaller price
   declines than comparable quality bonds. In addition, when rates rise and
   prepayments slow, the effective duration of mortgage-backed securities
   extends, resulting in increased volatility.

   Additional mortgage-backed securities in which the fund may invest include:
<PAGE>

  . Collateralized Mortgage Obligations (CMOs) CMOs are debt securities that are
   fully collateralized by a portfolio of mortgages or mortgage-backed
   securities. All interest and principal payments from the underlying mortgages
   are passed through to the CMOs in such a way as to create some classes with
   more stable average lives than the underlying mortgages and other classes
   with more volatile average lives. CMO classes may pay fixed or variable rates
   of interest, and certain classes have priority over others with respect to
   the receipt of prepayments.

  . Stripped Mortgage Securities Stripped mortgage securities (a type of
   potentially high-risk derivative) are created by separating the interest and
   principal payments generated by a pool of mortgage-backed securities or a CMO
   to create additional classes of securities. Generally, one class receives
   only interest payments (IOs), and another receives principal payments (POs).
   Unlike with other mortgage-backed securities and POs, the value of IOs tends
   to move in the same direction as interest rates. The funds can use IOs as a
   hedge against falling prepayment rates (interest rates are rising) and/or a
   bear market environment. POs can be used as a hedge against rising prepayment
   rates (interest rates are falling) and/or a bull market environment. IOs and
   POs are acutely sensitive to interest rate changes and to the rate of
   principal prepayments.

   A rapid or unexpected increase in prepayments can severely depress the price
   of IOs, while a rapid or unexpected decrease in prepayments could have the
   same effect on POs. Of course, under the opposite conditions these securities
   may appreciate in value. These securities can be very volatile in price and
   may have lower liquidity than most other mortgage-backed securities. Certain
   non-stripped CMO classes may also exhibit these qualities, especially those
   that pay variable rates of interest that adjust inversely with, and more
   rapidly than, short-term interest rates. In addition, if interest rates rise
   rapidly and prepayment rates slow more than expected, certain CMO classes, in
   addition to losing value, can exhibit characteristics of longer-term
   securities and become more volatile. There is no guarantee that fund
   investments in CMOs, IOs, or POs will be successful, and fund total return
   could be adversely affected as a result.


   Hybrid Instruments
   These instruments (a type of potentially high-risk derivative) can combine
   the characteristics of securities, futures, and options. For example, the
   principal amount or interest rate of a hybrid could be tied (positively or
   negatively) to the price of some commodity, currency, or securities index or
   another interest rate (each a "benchmark"). Hybrids can be used as an
   efficient means of pursuing a variety of investment goals, including duration
   management, and increased total return. Hybrids may or may not bear interest
   or pay dividends. The value of a hybrid or its interest rate may be a
   multiple of a benchmark and, as a result, may be leveraged and move (up or
   down) more steeply and rapidly than the benchmark. These benchmarks may be
   sensitive to economic and political events

   which cannot be readily foreseen by the purchaser of a hybrid. Under certain
   conditions, the redemption value of a hybrid could be zero. Thus, an
   investment in a hybrid may entail significant market risks that are not
   associated with a similar investment in a traditional, U.S.
   dollar-denominated bond that has a fixed principal amount and pays a fixed
   rate or floating rate of interest. The purchase of hybrids also exposes the
   fund to the credit risk of the issuer of the hybrid. These risks may cause
   significant fluctuations in the net asset values of the fund.


   One type of hybrid the fund may purchase is the bond index swap. The fund
   would purchase these in an effort to mimic all or a portion of the index. An
   index swap can help the fund replicate the index when the fund is small or
   when investing cash flow.

  . Hybrids can have volatile prices and limited liquidity, and their use may
   not be successful.

   Private Placements
   These securities are sold directly to a small number of investors, usually
   institutions. Unlike public offerings, such securities are not registered
   with the SEC. Although certain of these securities may be readily sold, for
   example, under Rule 144A, others may be illiquid, and their sale may involve
   substantial delays and additional costs.

   Operating policy  Fund investments in illiquid securities are limited to 15%
   of net assets.


 Types of Investment Management Practices

   Reserve Position

   Each fund will hold a certain portion of its assets in cash or cash
   equivalents. Each fund's reserve position can consist of shares of a T. Rowe
   Price internal money market fund and U.S. and foreign dollar-denominated
   money market securities, including repurchase agreements, in the two highest
   rating categories, maturing in one year or less. The reserve position
   provides flexibility in meeting redemptions, paying expenses, and in the
   timing of new investments.

   Borrowing Money and Transferring Assets
   Fund borrowings may be made from banks and other T. Rowe Price funds for
   temporary emergency purposes to facilitate redemption requests, or for other
   purposes consistent with fund policies as set forth in this prospectus. Such
   borrowings may be collateralized with fund assets, subject to restrictions.

   Fundamental policy  Borrowings may not exceed 33/1//\\/3/\\% of total fund
   assets.
<PAGE>


ABOUT THE FUNDS                               33
   Operating policy  Fund transfers of portfolio securities as collateral will
   not be made except as necessary in connection with permissible borrowings or
   investments, and then such transfers may not exceed 33/1//\\/3/\\% of fund
   total assets. Fund purchases of additional securities will not be made when
   borrowings exceed 5% of total assets.

   Futures and Options

   The funds may make such investments to provide an efficient means of
   maintaining liquidity while being invested in the market, to facilitate
   trading or to reduce transaction costs. The funds may also purchase call
   options on stock indices or bonds. Such options would be used in a manner
   similar to the funds' use of futures.

   Futures contracts and options prices can be highly volatile; using them could
   lower the funds' total returns and the potential loss from the use of futures
   can exceed the funds' initial investment in such contracts.

   Operating policies  Futures: Initial margin deposits and premiums on options
   used for non-hedging purposes will not exceed 5% of each fund's net asset
   value. Options on bonds or indices: The funds will not commit more than 5% of
   total assets to premiums when purchasing call options.

   Lending of Portfolio Securities

   Fund securities may be lent to broker-dealers, other institutions, or other
   persons to earn additional income. The principal risk is the potential
   insolvency of the broker-dealer or other borrower. In this event, a fund
   could experience delays in recovering its securities, and capital losses.

   Fundamental policy  The value of loaned securities may not exceed
   33/1//\\/3/\\% of total fund assets.


   U.S. Bond Index Fund

   When-Issued Securities and Forward Commitment Contracts

   The fund may purchase securities on a when-issued or delayed delivery basis
   or may purchase or sell securities on a forward commitment basis. There is no
   limit on fund investments in these securities. The price of these securities
   is fixed at the time of the commitment to buy, but delivery and payment can
   take place a month or more later. During the interim period, the market value
   of the securities can fluctuate, and no interest accrues to the purchaser. At
   the time of delivery, the value of the securities may be more or less than
   the purchase or sale price. To the extent the fund remains fully or almost
   fully invested (in securities with a remaining maturity of more than one
   year) at the same time it purchases these securities, there will be greater
   fluctuations in the fund's net asset value than if the fund did not purchase
   them.

   Portfolio Turnover
   Each fund will not generally trade in securities for short-term profits, but,
   under unusual circumstances, securities may be purchased and sold without
   regard to the length of time held. The portfolio turnover rates for the
   fiscal years ending December 31 for the Equity Index 500, Extended Equity
   Market Index and Total Equity Market Index Funds are listed in the table in
   the Financial Highlights section.

   Funds

   Table 5, which provides information about each fund's financial history, is
   based on a single share outstanding throughout each fiscal year. Each fund's
   section of the table is part of the fund's financial statements, which are
   included in its annual report and are incorporated by reference into the
   Statement of Additional Information (available upon request). The total
   returns in the tables represent the rate that an investor would have earned
   or lost on an investment in each fund (assuming reinvestment of all dividends
   and distributions and no payment of account or (if applicable) redemption
   fees). The financial statements in the annual report were audited by the
   funds' independent accountants, PricewaterhouseCoopers LLP.

                                                       Tax Identification Number

We must have your correct Social Security or tax identification number on a
signed New Account Form or W-9 Form. Otherwise, federal law requires the funds
to withhold a percentage (currently 31%) of your dividends, capital gain
distributions, and redemptions, and may subject you to an IRS fine. If this
information is not received within 60 days after your account is established,
your account may be redeemed, priced at the NAV on the date of redemption.

Always verify your transactions by carefully reviewing the confirmation we send
you. Please report any discrepancies to Shareholder Services promptly.

 RIGHTS RESERVED BY THE FUNDS
 ----------------------------------------------------------
T. Rowe Price funds and their agents reserve the following rights: (1) to waive
or lower investment minimums; (2) to accept initial purchases by telephone or
mailgram; (3) to refuse any purchase or exchange order; (4) to cancel or rescind
any purchase or exchange order (including, but not limited to, orders deemed to
result in excessive trading, market timing, fraud, or 5% ownership) upon notice
to the shareholder within five business days of the trade or if the written
confirmation has not been received by the shareholder, whichever is sooner; (5)
to freeze any account and suspend account services when notice has been received
of a dispute between the registered or beneficial account owners or there is
reason to believe a fraudulent transaction may occur; (6) to otherwise modify
the conditions of purchase and any services at any time; and (7) to act on
instructions believed to be genuine. These actions will be taken when, in the

T. ROWE PRICE                                 44

a substantial redemption in a large account, as a matter of general policy, no
shareholder or group of shareholders controlled by the same person or group of
persons will knowingly be permitted to purchase in excess of 5% of the
outstanding shares of the fund, except upon approval of the fund's management.

            Shareholder Services 1-800-225-5132 Investor Services 1-800-638-5660

Many services are available to you as a T. Rowe Price shareholder; some you
receive automatically, and others you must authorize or request on the New
Account Form. By signing up for services on the New Account Form rather than
later on, you avoid having to complete a separate form and obtain a signature
guarantee. This section discusses some of the services currently offered. Our
Services Guide, which we mail to all new shareholders, contains detailed
descriptions of these and other services.

Note: Corporate and other institutional accounts require an original or
certified resolution to establish services and to redeem by mail. For more
information, call Investor Services.

We offer a wide range of plans for individuals, institutions, and large and
small businesses: Traditional IRAs, Roth IRAs, SIMPLE IRAs, SEP-IRAs, Keoghs
(profit sharing, money purchase pension), 401(k)s, and 403(b)(7)s. For
information on IRAs or our no-load variable annuity, call Investor Services. For
information on all other retirement plans, please call our Trust Company at

By ACH
With no charges to pay, you can initiate a purchase or redemption for as little
as $100 or as much as $100,000 between your bank account and fund account using
the ACH network. Enter instructions via Tele*Access or your personal computer,
or call Shareholder Services.



By Wire
Electronic transfers can be conducted via bank wire. There is currently a $5 fee
for wire redemptions under $5,000, and your bank may charge for incoming or
outgoing wire transfers regardless of size.

                                                                    Checkwriting

(Not available for equity funds, or the High Yield, Emerging Markets Bond, or
U.S. Bond Index Funds) You may write an unlimited number of free checks on any
money market fund, and most bond funds, with a minimum of $500 per check. Keep
in mind, however, that a check results in a redemption; a check written on a
bond fund will create a taxable event which you and we must report to the IRS.
