T. Rowe Price Prime Reserve Fund - -------------------------------------------------------------------------------- Certified Annual Report Performance Comparison - -------------------------------------------------------------------------------- This chart shows the value of a hypothetical $10,000 investment in the fund over the past 10 fiscal year periods or since inception (for funds lacking 10-year records).

Past performance cannot guarantee future results. T. Rowe Price Prime Reserve Fund - -------------------------------------------------------------------------------- Certified Annual Report Dear Shareholder, Reflecting very low money market rates, your fund had a positive return of 0.51% during the 12 months ended May 31, 2004. It outperformed the Lipper average of similarly managed funds during the period, as shown in the table on the previous page, primarily because we emphasized higher-yielding money market securities for most of the last year.

The fund's average weighted maturity will not exceed 90 days, and we will not purchase any security with a maturity longer than 13 months. Portfolio Characteristics - -------------------------------------------------------------------------------- Periods Ended 5/31/03 5/31/04 - -------------------------------------------------------------------------------- Price Per Share $ 1.00 $ 1.00 Dividend Yield (7-Day Simple) * 0.62% 0.51% Weighted Average Maturity (days) 53 43 Weighted Average Quality ** First Tier First Tier * Dividends earned for the last seven days of the period indicated are annualized and divided by the fund's net asset value. ** All securities purchased in the money fund are rated in the two highest categories (tiers) as established by the national rating agencies or, if unrated, are deemed of comparable quality by T. Rowe Price. Note: A money fund's yield more closely reflects its current earnings than the total return. As shown in the Portfolio Characteristics table, the fund's weighted average maturity slipped from 53 days to 43 days during its fiscal year. Its simple seven-day dividend yield also declined from 0.62% to 0.51%. The fund's price per share remained steady at $1.00, and its weighted average quality remained very high because we continued to focus primarily on money market instruments with the highest credit quality. We thank you for your continued support. Respectfully submitted, James S. Riepe Chairman June 15, 2004 T.

Rowe Price Prime Reserve Fund - -------------------------------------------------------------------------------- Certified Annual Report May 31, 2004 Notes to Financial Statements - -------------------------------------------------------------------------------- NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES T. Rowe Price Prime Reserve 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 January 26, 1976. The fund seeks preservation of capital, liquidity, and, consistent with these, the highest possible current income. From November 1, 1998 through November 25, 2002, the fund also offered a second class of shares. The T. Rowe Price Prime Reserve-PLUS Class (PLUS Class) provided expanded shareholder services, the cost of which was borne by its shareholders. Each class had exclusive voting rights on matters related solely to that class, separate voting rights on matters which related to both classes, and, in all other respects, the same rights and obligations as the other class. On November 25, 2002, all outstanding shares of the PLUS Class were transferred into the Prime Reserve Fund class at their value on that date, and the PLUS class was closed. The transfer was nontaxable to investors. 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 Securities are valued at amortized cost. Assets and liabilities for which such valuation procedures 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. Credits The fund earns credits on temporarily uninvested cash balances at the custodian that reduce the fund's custody charges. Custody expense in the accompanying financial statements is presented before reduction for credits, which are reflected as expenses paid indirectly. Investment Transactions, Investment Income, and Distributions Income and expenses are recorded on the accrual basis. Premiums and discounts on debt securities are amortized for financial reporting purposes. Investment transactions are accounted for on the trade date. Realized gains and losses are reported on the identified cost basis. Distributions to shareholders are recorded on the ex-dividend date. Income distributions are declared on a daily basis and paid monthly. Other 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 - 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 significantly 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. Distributions during the year ended May 31, 2004 totaled $26,839,000 and were characterized as ordinary income for tax purposes. At May 31, 2004, the tax-basis components of net assets were as follows: Undistributed ordinary income $ 736,000 Paid-in capital 5,052,110,000 Net assets $ 5,052,846,000 -------------------- The fund intends to retain realized gains to the extent of available capital loss carryforwards for federal income tax purposes. During the fiscal year ended May 31, 2004, the fund utilized $22,000 of capital loss carryforwards. For the year ended May 31, 2004, the fund recorded the following permanent reclassifications to reflect tax character. Reclassifications to paid-in capital relate primarily to a tax practice that treats a portion of the proceeds from each redemption of capital shares as a distribution of taxable net investment income and/or realized capital gain. Results of operations and net assets were not affected by these reclassifications. Undistributed net realized gain $ (64,000) Paid-in capital 64,000 At May 31, 2004, the cost of investments for federal income tax purposes was $4,985,384,000. NOTE 3- 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 0.05 % 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 May 31, 2004, the effective annual group fee rate was 0.32%, and investment management fee payable totaled $1,559,000. 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 $8,434,000 for the year ended May 31, 2004, of which $745,000 was payable at period-end. T.

Other fees include the registrant's pro-rata share of amounts for agreed-upon procedures in conjunction with service contract approvals by the registrant's Board of Directors/Trustees. (e)(1) The registrant's audit committee has adopted a policy whereby audit and non-audit services performed by the registrant's principal accountant for the registrant, its investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant require pre-approval in advance at regularly scheduled audit committee meetings. If such a service is required between regularly scheduled audit committee meetings, pre-approval may be authorized by one audit committee member with ratification at the next scheduled audit committee meeting. Waiver of pre-approval for audit or non-audit services requiring fees of a de minimis amount is not permitted. (2) No services included in (b) - (d) above were approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Rowe Price Funds. (h) All non-audit services rendered in (g) above were pre-approved by the registrant's audit committee. Accordingly, these services were considered by the registrant's audit committee in maintaining the principal accountant's independence. Item 5. Audit Committee of Listed Registrants. Not applicable.
