NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

     T. Rowe Price Short-Term Bond Fund, Inc. (the fund) is registered under the
     Investment Company Act of 1940 (the 1940 Act) as a diversified, open-end
     management investment company and commenced operations on March 2, 1984.
     The fund seeks a high level of income consistent with minimal fluctuation
     in principal value and liquidity.

     The accompanying financial statements were prepared in accordance with
     accounting principles generally accepted in the United States of America,
     which require the use of estimates made by fund management.

     Valuation
     The fund values its investments and computes its net asset value per share
     at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET,
     each day that the NYSE is open for business. Debt securities are generally
     traded in the over-the-counter market. Securities with original maturities
     of one year or more are valued at prices furnished by dealers who make
     markets in such securities or by an independent pricing service, which
     considers yield or price of bonds of comparable quality, coupon, maturity,
     and type, as well as prices quoted by dealers who make markets in such
     securities. Securities with original maturities of less than one year are
     stated at fair value, which is determined by using a matrix system that
     establishes a value for each security based on bid-side money market
     yields.

     Investments in mutual funds are valued at the mutual fund's closing net
     asset value per share on the day of valuation. Financial futures contracts
     are valued at closing settlement prices. Other investments and those for
     which the above valuation procedures are inappropriate or are deemed not
     to reflect fair value are stated at fair value as determined in good faith
     by the T. Rowe Price Valuation Committee, established by the fund's Board
     of Directors.

     Most foreign markets close before the NYSE. Normally, developments that
     could affect the values of securities that occur between the close of a
     foreign market and the close of the NYSE will not be reflected in security
     valuations used by the fund to compute its share price. However, if
     developments are so significant that they will, in the judgment of the
     fund, clearly and materially affect security values, such valuations may be
     adjusted to reflect the estimated fair value of the securities as of the
     close of the NYSE, as determined in good faith by the T. Rowe Price
     Valuation Committee, established by the fund's Board of Directors.




     Currency Translation
     Assets, including investments, and liabilities denominated in foreign
     currencies are translated into U.S. dollar values each day at the
     prevailing exchange rate, using the mean of the bid and ask prices of such
     currencies against U.S. dollars as quoted by a major bank. Purchases and
     sales of securities, income, and expenses are translated into U.S. dollars
     at the prevailing exchange rate on the date of the transaction. The effect
     of changes in foreign currency exchange rates on realized and unrealized
     security gains and losses is reflected as a component of security gains and
     losses.

     Expenses Paid Indirectly
     Credits earned on temporarily uninvested cash balances at the custodian are
     used to reduce the fund's custody charges. Custody expense in the
     accompanying statement of operations is presented before reduction for
     credits, which totaled $2,000 for the six months ended November 30, 2003.

     Other
     Income and expenses are recorded on the accrual basis. Investment
     transactions are accounted for on the trade date. Realized gains and losses
     are reported on the identified cost basis. Premiums and discounts on debt
     securities are amortized for financial reporting purposes. Distributions to
     shareholders are recorded by the fund on the ex-dividend date. Dividends
     from mutual fund investments are reflected as dividend income; capital gain
     distributions from mutual fund investments are reflected as realized
     gain/loss. Payments ("variation margin") made or received by the fund to
     settle the daily fluctuations in the value of futures contracts are
     recorded as unrealized gains or losses until the contracts are closed.
     Unrealized gains and losses on futures contracts are included in Change in
     net unrealized gain or loss in the accompanying financial statements. In
     the normal course of business, the fund enters into contracts that provide
     general indemnifications. The fund's maximum exposure under these
     arrangements is dependent on claims that may be made against the fund in
     the future and, therefore, cannot be estimated; however, based on
     experience, the risk of material loss from such claims is considered
     remote.

NOTE 2 - INVESTMENT TRANSACTIONS

     Consistent with its investment objective, the fund engages in the following
     practices to manage exposure to certain risks or enhance performance. The
     investment objective, policies, program, and risk factors of the fund are
     described more fully in the fund's prospectus and Statement of Additional
     Information.

     Forward Currency Exchange Contracts
     During the six months ended November 30, 2003, the fund was a party to
     forward currency exchange contracts under which



     it is obligated to exchange currencies at specified future dates and
     exchange rates. Risks arise from the possible inability of counterparties
     to meet the terms of their agreements and from movements in currency
     values.

     Futures Contracts
     During the six months ended November 30, 2003, the fund was a party to
     futures contracts, which provide for the future sale by one party and
     purchase by another of a specified amount of a specific financial
     instrument at an agreed upon price, date, time, and place. Risks arise from
     possible illiquidity of the futures market and from movements in security
     values and interest rates.

     Securities Lending
     The fund lends its securities to approved brokers to earn additional
     income. It receives as collateral cash and U.S. government securities
     valued at 102% to 105% of the value of the securities on loan. Cash
     collateral is invested in a money market pooled account managed by the
     fund's lending agent in accordance with investment guidelines approved by
     fund management. Collateral is maintained over the life of the loan in an
     amount not less than the value of loaned securities, as determined at the
     close of fund business each day; any additional collateral required due to
     changes in security values is delivered to the fund the next business day.
     Although risk is mitigated by the collateral, the fund could experience a
     delay in recovering its securities and a possible loss of income or value
     if the borrower fails to return the securities. Securities lending revenue
     recognized by the fund consists of earnings on invested collateral and
     borrowing fees, net of any rebates to the borrower and compensation to the
     lending agent. At November 30, 2003, there were no securities on loan.

     Other
     Purchases and sales of portfolio securities, other than short-term and U.S.
     government securities, aggregated $361,386,000 and $173,491,000,
     respectively, for the six months ended November 30, 2003. Purchases and
     sales of U.S. government securities aggregated $338,941,000 and
     $379,742,000, respectively, for the six months ended November 30, 2003.

NOTE 3 - FEDERAL INCOME TAXES

     No provision for federal income taxes is required since the fund intends to
     continue to qualify as a regulated investment company under Subchapter M of
     the Internal Revenue Code and distribute to shareholders all of its taxable
     income and gains. Federal income tax regulations differ from generally
     accepted accounting principles; therefore, distributions determined in
     accordance with tax regulations may differ in amount or character from net
     investment income and realized gains for financial reporting purposes.
     Financial reporting records are adjusted for permanent


     book/tax differences to reflect tax character. Financial records are
     not adjusted for temporary differences. The amount and character of
     tax-basis distributions and composition of net assets are finalized at
     fiscal year-end; accordingly, tax-basis balances have not been determined
     as of November 30, 2003.

     The fund intends to retain realized gains to the extent of available
     capital loss carryforwards. As of May 31, 2003, the fund had $19,510,000 of
     unused capital loss carryforwards, of which $10,744,000 expire in 2004,
     $2,405,000 expire in 2005, and $6,361,000 thereafter through 2009.

     At November 30, 2003, the cost of investments for federal income tax
     purposes was $1,225,584,000. Net unrealized gain aggregated $13,463,000 at
     period-end, of which $17,817,000 related to appreciated investments and
     $4,354,000 related to depreciated investments.

NOTE 4- RELATED PARTY TRANSACTIONS

     The fund is managed by T. Rowe Price Associates, Inc. (the manager or Price
     Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. The
     investment management agreement between the fund and the manager provides
     for an annual investment management fee, which is computed daily and paid
     monthly. The fee consists of an individual fund fee, equal to 0.10% of the
     fund's average daily net assets, and the fund's pro-rata share of a group
     fee. The group fee is calculated based on the combined net assets of
     certain mutual funds sponsored by Price Associates (the group) applied to a
     graduated fee schedule, with rates ranging from 0.48% for the first $1
     billion of assets to 0.295% for assets in excess of $120 billion. The
     fund's portion of the group fee is determined by the ratio of its average
     daily net assets to those of the group. At November 30, 2003, the effective
     annual group fee rate was 0.32%, and investment management fee payable
     totaled $326,000.

     The fund is also subject to a contractual expense limitation through
     September 30, 2004. During the limitation period, the manager is required
     to waive its management fee and reimburse the fund for any expenses,
     excluding interest, taxes, brokerage commissions, and extraordinary
     expenses, that would otherwise cause the fund's ratio of total expenses to
     average net assets (expense ratio) to exceed its expense limitation of
     0.55%. Through September 30, 2006, the fund is required


     to repay the manager for expenses previously reimbursed and management fees
     waived to the extent its net assets have grown or expenses have declined
     sufficiently to allow repayment without causing the fund's expense ratio to
     exceed its expense limitation. At November 30, 2003, management fees waived
     remain subject to repayment by the fund in the following amounts: $961,000
     through May 31, 2004, and $1,117,000 through September 30, 2006.

     In addition, the fund has entered into service agreements with Price
     Associates and two wholly owned subsidiaries of Price Associates
     (collectively, Price). Price Associates computes the daily share price and
     maintains the financial records of the fund. T. Rowe Price Services, Inc.,
     provides shareholder and administrative services in its capacity as the
     fund's transfer and dividend disbursing agent. T. Rowe Price Retirement
     Plan Services, Inc., provides subaccounting and recordkeeping services for
     certain retirement accounts invested in the fund. Expenses incurred
     pursuant to these service agreements totaled $536,000 for the six months
     ended November 30, 2003, of which $92,000 was payable at period-end.

     Additionally, the fund is one of several mutual funds in which certain
     college savings plans managed by Price Associates may invest. As approved
     by the fund's Board of Directors, shareholder servicing costs associated
     with each college savings plan are borne by the fund in proportion to the
     average daily value of its shares owned by the college savings plan. For
     the six months ended November 30, 2003, the fund was charged $101,000 for
     shareholder servicing costs related to the college savings plans, of which
     $73,000 was for services provided by Price and $39,000 was payable at
     period-end. At November 30, 2003, approximately 8.5% of the outstanding
     shares of the fund were held by college savings plans.

     The fund is also one of several mutual funds sponsored by Price Associates
     (underlying Price funds) in which the T. Rowe Price Spectrum Funds
     (Spectrum Funds) and T. Rowe Price Retirement Funds (Retirement Funds) may
     invest. Neither the Spectrum Funds nor the Retirement Funds invest in the
     underlying Price funds for the purpose of exercising management or control.
     Pursuant to separate, special servicing agreements, expenses associated
     with the operation of the Spectrum and Retirement Funds are borne by each
     underlying Price fund to the extent of estimated savings to it and in
     proportion to the average daily value of its shares owned by the Spectrum
     and Retirement Funds, respectively. Expenses allocated under these
     agreements are reflected as shareholder servicing expenses in the





     accompanying financial statements. For the six months ended November 30,
     2003, the fund was allocated $48,000 of Spectrum Funds' expenses and
     $46,000 of Retirement Funds' expenses. Of these amounts, $46,000 related to
     services provided by Price and $43,000 was payable at period-end. At
     November 30, 2003, approximately 6.8% of the outstanding shares of the fund
     were held by the Spectrum Funds and 1.9% were held by the Retirement Funds.

     The fund may invest in the T. Rowe Price Reserve Investment Fund and the T.
     Rowe Price Government Reserve Investment Fund (collectively, the Reserve
     Funds), open-end management investment companies managed by Price
     Associates. The Reserve Funds are offered as cash management options only
     to mutual funds, trusts, and other accounts managed by Price Associates
     and/or its affiliates, and are not available to the public. The Reserve
     Funds pay no investment management fees. During the six months ended
     November 30, 2003, dividend income from the Reserve Funds totaled
     $1,048,000.
