ROWE PRICE SCIENCE & TECHNOLOGY FUND - -------------------------------------------------------------------------------- Fellow Shareholders The broad stock market ended 2004 near its highest level of the year. Most of the year's gains were due to a rally that commenced on October 25, triggered by falling oil prices, continuing economic growth, and the belief that the U.S. presidential election would be resolved without controversy. The widely followed Dow Jones Industrial Average registered the smallest gain, while the broader market indices, including the S&P 500 Stock Index and Nasdaq Composite, were stronger. Technology stocks were weak for most of the year but finished higher after bottoming in August, driven largely by a solid quarter from software companies and an improving inventory picture in semiconductors. PERFORMANCE COMPARISON - -------------------------------------------------------------------------------- Periods Ended 12/31/04 6 Months 12 Months - -------------------------------------------------------------------------------- Science & Technology Fund 1.60% 1.60% Science & Technology Fund--Advisor Class 1.54 1.60 S&P 500 Stock Index 7.19 10.88 Lipper Science & Technology Funds Index 3.57 4.11 Your fund ended the year marginally higher, with identical returns of 1.60% for both the 6- and 12-month periods shown in the table since first-half performance was precisely flat. (Advisor Class returns were lower over the year, reflecting higher fees.) Returns lagged both the unmanaged Standard & Poor's 500 Stock Index and the Lipper Science & Technology Funds Index. Relative performance versus Lipper for the year was due to both sector allocation and stock selection. Positive contributions from software stocks were offset by the negative impact of telecom equipment and semiconductor stocks. MARKET ENVIRONMENT Following stellar returns in 2003, investors shifted their focus from the strength of the economic recovery to its sustainability. Rising interest rates, the weakening dollar, and escalating oil prices became fodder for the business press. Investment returns were strongest in the fourth quarter due more to end-of-year seasonality than to acceleration in underlying growth. While all technology sectors enjoyed good returns in 2003, there was a marked divergence between the best and worst performers of 2004. Investors chased areas offering growth and shunned those in the midst of temporary slowdowns. Both the hardware and Internet segments rose more than 20% while semiconductors declined almost 15%. Software returns fell between the extremes. Spending to meet the requirements of the Sarbanes-Oxley Act, designed to improve corporate governance and restore investor confidence, drained budget dollars from information technology (IT). This diversion of funds was most evident in second-quarter results for software, where short-term spending is highly discretionary. Semiconductor companies were mired in excess inventory in the latter half of 2003 and the beginning of 2004, which led to disappointing results in the third quarter and materially lower earnings guidance for 2005. With the post-bubble recovery solidly under way, technology companies reexamined their pertinent markets and potential growth within them--a process that drove some major decisions and subsequent changes in industry structure. In the software segment, PeopleSoft finally agreed to be acquired by Oracle in the largest software merger ever. In late 2004, Symantec and VERITAS Software announced their agreement to combine two previously unrelated markets, security and storage software. Within hardware, IBM decided to sell its personal computing business unit to Lenovo Group, China's largest PC manufacturer. Although consolidation should improve pricing within technology, it is also a sign of a maturing industry. PORTFOLIO REVIEW We significantly increased our exposure to semiconductors and marginally increased it to telecom equipment stocks during the past six months. During the period, we reduced our allocation to software and media. However, since our analysis indicated a better risk/reward profile for software relative to the overall technology sector, software was still the largest industry represented in the portfolio. Our largest purchases were Intel, Red Hat, and Maxim Integrated Products, while our largest sales included VERITAS Software, Intuit, and McAfee. (Please refer to our portfolio of investments for a complete listing of the portfolio's holdings and the amount each represents of the portfolio.) Among portfolio holdings, Dell, VeriSign, QLogic, and Oracle were the fund's best contributors over the past six months, while laggards included Cisco Systems, Red Hat, and Analog Devices. Cisco Systems continued to execute well throughout 2004 but sales growth appears to be slowing as we enter 2005. Red Hat failed to meet its growth targets in its most recent quarters, and investors are worried about the pricing environment in the LINUX market. After generating growth in excess of 35% in its July quarter, Analog Devices saw a sudden order slowdown in the following quarter as customers chose to reduce component inventories. Although the results for each of these companies were disappointing, we remain confident about their long-term prospects. [Graphic Omitted] INDUSTRY DIVERSIFICATION - -------------------------------------------------------------------------------- Software 27% Semiconductors 24% Hardware 13% Telecom Equipment 11% Media 9% IT Services 8% Healthcare 3% Other & Reserves 5% The fund remains broadly diversified across the principal segments of the science and technology sector. Stocks of software, semiconductors, hardware, and telecom equipment companies accounted for 75% of the portfolio, and media, IT services, and health care constituted an additional 20%. The fund's 25 largest holdings, which included Microsoft, Cisco Systems, and Dell, represented 58.8% of net assets. At the end of December, the average market capitalization for the fund was $17.6 billion, compared with $19.9 billion six months ago. OUTLOOK In the near term, we are cautious since the first quarter is often challenging given seasonal IT spending patterns, with many tech companies experiencing a sequential sales decline. With the strong returns realized since the low for the year in August, it may prove difficult for tech stocks to continue their ascent with little incremental positive information feeding the momentum. Technology stocks have recovered from their nadir in October 2002, but most of the rally has occurred without a resurgence in corporate IT spending. Despite record cash levels and historically high cash flow from operations, companies have remained cautious about spending on IT. The urgency to stay on the forefront of technology in the late 1990s has dissipated and is no longer propelling chief information officers to seek larger budgets. We expect this environment of steady-but-modest improvement to persist because of the lower obsolescence risks associated with retaining older technologies. Over the last 15 years, the number of Internet users and wireless subscribers has grown to 850 million and 1.5 billion, respectively, their sheer size making the historic growth rates impossible to repeat. Emerging technologies--wireless broadband, Voice over Internet Protocol (VoIP), digital television, and radio frequency identification (RFID)--are evolutionary rather than revolutionary. In other words, the next-generation wireless phone with built-in camera capable of receiving e-mail is simply a replacement for an older-generation phone rather than an initial adoption. If personal computers and wireless are more mature markets, where are the opportunities going forward? First, certain semiconductor companies still offer good long-term growth potential, but their customers need to reduce inventories before order growth resumes. Second, worldwide broadband penetration currently stands at less than 15% but is inexorably moving higher. Finally, the looming battle between cable companies and traditional telephone carriers is likely to lead to incremental spending on communications equipment. We are shifting the portfolio from stocks that have already benefited from general economic improvement and redeploying assets to those less likely to benefit from an increase in corporate spending. Stock valuations appear reasonable, and our focus remains on companies with growing market share and strong management teams that are positioned to benefit from an improving economic and IT spending environment. Technology is still the principal means of improving corporate productivity, and we remain upbeat about prospects for this segment of the equities markets over the long term. As always, we appreciate your continued support. Respectfully submitted, Michael F. Sola President of the fund and chairman of its Investment Advisory Committee January 14, 2005 The committee chairman has day-to-day responsibility for managing the portfolio and works with committee members in developing and executing the fund's investment program. - -------------------------------------------------------------------------------- RISKS OF INVESTING IN THE FUND Funds that invest only in specific industries will experience greater volatility than funds investing in a broad range of industries. Technology stocks, historically, have experienced unusually wide price swings, both up and down. The potential for wide variation in performance reflects the special risks common to companies in the rapidly changing field of technology. For example, products or services that at first appear promising may not prove commercially successful and may become obsolete quickly. Earnings disappointments and intense competition for market share can result in sharp price declines.

Returns do not reflect taxes that the shareholder may pay on distributions or the redemption of shares. When assessing performance, investors should consider both short- and long-term returns. T. ROWE PRICE SCIENCE & Technology Fund - -------------------------------------------------------------------------------- FUND EXPENSE EXAMPLE - -------------------------------------------------------------------------------- As a mutual fund shareholder, you may incur two types of costs: (1) transaction costs such as redemption fees or sales loads and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other fund expenses. The following example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the most recent six-month period and held for the entire period. Please note that the fund has two share classes: The original share class ("investor class") charges no distribution and service (12b-1) fee. Advisor Class shares are offered only through unaffiliated brokers and other financial intermediaries and charge a 0.25% 12b-1 fee. Each share class is presented separately in the table. Actual Expenses The first line of the following table ("Actual") provides information about actual account values and expenses based on the fund's actual returns. You may use the information in this line, together with your account balance, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The information on the second line of the table ("Hypothetical") is based on hypothetical account values and expenses derived from the fund's actual expense ratio and an assumed 5% per year rate of return before expenses (not the fund's actual return). You may compare the ongoing costs of investing in the fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. Note: T. Rowe Price charges an annual small-account maintenance fee of $10, generally for accounts with less than $2,000 ($500 for UGMA/UTMA). The fee is waived for any investor whose T. Rowe Price mutual fund accounts total $25,000 or more, accounts employing automatic investing, and IRAs and other retirement plan accounts that utilize a prototype plan sponsored by T. Rowe Price (although a separate custodial or administrative fee may apply to such accounts). This fee is not included in the accompanying table. If you are subject to the fee, keep it in mind when you are estimating the ongoing expenses of investing in the fund and when comparing the expenses of this fund with other funds. You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs, such as redemption fees or sales loads. Therefore, the second line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. To the extent a fund charges transaction costs, however, the total cost of owning that fund is higher. T.

T. ROWE PRICE SCIENCE & TECHNOLOGY FUND - -------------------------------------------------------------------------------- December 31, 2004 NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES T. Rowe Price Science & Technology Fund, Inc. (the fund) is registered under the Investment Company Act of 1940 (the 1940 Act) as a diversified, open-end management investment company. The fund seeks to provide long-term capital appreciation. The fund has two classes of shares: the Science & Technology Fund original share class, referred to in this report as the Investor Class, offered since September 30, 1987, and Science & Technology Fund--Advisor Class (Advisor Class), offered since March 31, 2000. Advisor Class shares are sold only through unaffiliated brokers and other unaffiliated financial intermediaries that are compensated by the class for distribution, shareholder servicing, and/or certain administrative services under a Board-approved Rule 12b-1 plan. Each class has exclusive voting rights on matters related solely to that class, separate voting rights on matters that relate to both classes, and, in all other respects, the same rights and obligations as the other class. 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. Equity securities listed or regularly traded on a securities exchange or in the over-the-counter market are valued at the last quoted sale price or, for certain markets, the official closing price at the time the valuations are made, except for OTC Bulletin Board securities, which are valued at the mean of the latest bid and asked prices. A security that is listed or traded on more than one exchange is valued at the quotation on the exchange determined to be the primary market for such security. Listed securities not traded on a particular day are valued at the mean of the latest bid and asked prices for domestic securities and the last quoted sale price for international securities. Investments in mutual funds are valued at the mutual fund's closing net asset value per share on the day of valuation. Other investments, including restricted securities, 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 close of trading on the NYSE. If the fund determines that developments between the close of a foreign market and the close of the NYSE will, in its judgment, materially affect the value of some or all of its portfolio securities, which in turn will affect the fund's share price, the fund will adjust the previous closing prices to reflect the 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. A fund may also fair value securities in other situations, such as when a particular foreign market is closed but the fund is open. In deciding whether to make fair value adjustments, the fund reviews a variety of factors, including developments in foreign markets, the performance of U.S. securities markets, and the performance of instruments trading in U. S. markets that represent foreign securities and baskets of foreign securities. The fund uses outside pricing services to provide it with closing market prices and information used for adjusting those prices. The fund cannot predict how often it will use closing prices and how often it will adjust those prices. As a means of evaluating its fair value process, the fund routinely compares closing market prices, the next day's opening prices in the same markets, and adjusted prices. 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 asked 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. Class Accounting The Advisor Class pays distribution, shareholder servicing, and/or certain administrative expenses in the form of Rule 12b-1 fees, in an amount not exceeding 0.25% of the class's average daily net assets. Shareholder servicing, prospectus, and shareholder report expenses incurred by each class are charged directly to the class to which they relate. Expenses common to both classes, investment income, and realized and unrealized gains and losses are allocated to the classes based upon the relative daily net assets of each class. Rebates and Credits Subject to best execution, the fund may direct certain security trades to brokers who have agreed to rebate a portion of the related brokerage commission to the fund in cash. Commission rebates are included in realized gain on securities in the accompanying financial statements and totaled $407,000 for the year ended December 31, 2004. Additionally, 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. Investment Transactions, Investment Income, and Distributions Income and expenses are recorded on the accrual basis. Dividends received from mutual fund investments are reflected as dividend income; capital gain distributions are reflected as realized gain/loss. Dividend income and capital gain distributions are recorded on the ex-dividend date. 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 and paid by each class on an annual basis. Capital gain distributions, if any, are declared and paid by the fund, typically on an annual basis. During the year ended December 31, 2004, the fund received a one-time special dividend on a security held in its portfolio (Microsoft Corp.). The dividend, which totaled $24,948,000, represents 63% of dividend income reflected in the accompanying financial statements and is not expected to recur. 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 - 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. Restricted Securities The fund may invest in securities that are subject to legal or contractual restrictions on resale. 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, and prompt sale at an acceptable price may be difficult. 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 trust 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 December 31, 2004, there were no securities on loan. Other Purchases and sales of portfolio securities, other than short-term securities, aggregated $2,468,792,000 and $3,134,246,000, respectively, for the year ended December 31, 2004. 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 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. There were no distributions in the year ended December 31, 2004. At December 31, 2004, the tax-basis components of net assets were as follows: - -------------------------------------------------------------------------------- Unrealized appreciation $ 404,941,000 Unrealized depreciation (536,277,000) Net unrealized appreciation (depreciation) (131,336,000) Capital loss carryforwards (5,767,586,000) Paid-in capital 10,405,960,000 Net assets $ 4,507,038,000 ------------------ The fund intends to retain realized gains to the extent of available capital loss carryforwards for federal income tax purposes. During the year ended December 31, 2004, the fund utilized $500,381,000 of capital loss carryforwards. As of December 31, 2004, the fund had $3,733,946 of capital loss carryforwards that expire in 2009, $1,904,219,000 that expire in 2010, and $129,421,000 that expire in 2011. For the year ended December 31, 2004, the fund recorded the following permanent reclassifications to reflect tax character. Reclassifications to paid-in capital relate primarily to the current net operating loss. Results of operations and net assets were not affected by these reclassifications. - -------------------------------------------------------------------------------- Undistributed net investment income $ 6,857,000 Undistributed net realized gain 62,000 Paid-in capital (6,919,000) At December 31, 2004, the cost of investments for federal income tax purposes was $4,638,533,000. 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 0.35% 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 December 31, 2004, the effective annual group fee rate was 0.31%, and investment management fee payable totaled $2,547,000. The Advisor Class is also subject to a contractual expense limitation through April 30, 2006. During the limitation period, the manager is required to waive its management fee and reimburse the class for any expenses, excluding interest, taxes, brokerage commissions, and extraordinary expenses, that would otherwise cause the class's ratio of total expenses to average net assets (expense ratio) to exceed its expense limitation of 1.15%. Through April 30, 2008, the class 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 class's expense ratio to exceed its expense limitation. Pursuant to this agreement, at December 31, 2004, there were no amounts subject to repayment. For the year ended December 31, 2004, the Advisor Class operated below its expense limitation. 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 prices 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 Investor Class. For the year ended December 31, 2004, expenses incurred pursuant to these service agreements were $93,000 for Price Associates, $5,753,000 for T. Rowe Price Services, Inc., and $3,657,000 for T. Rowe Price Retirement Plan Services, Inc. At period-end, a total of $1,075,000 of these expenses was payable. 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 year ended December 31, 2004, the fund was charged $31,000 for shareholder servicing costs related to the college savings plans, of which $23,000 was for services provided by Price. At December 31, 2004, approximately 0.3% of the outstanding Investor Class were held by college savings plans. 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 and affiliates of the fund. The Reserve Funds are offered as cash management options to mutual funds, trusts, and other accounts managed by Price Associates and/or its affiliates, and are not available for direct purchase by members of the public. The Reserve Funds pay no investment management fees. During the year ended December 31, 2004, dividend income from the Reserve Funds totaled $891,000, and the value of shares of the Reserve Funds held at December 31, 2004 and December 31, 2003 was $158,401,000 and $68,824,000, respectively. As of December 31, 2004, T. Rowe Price Group, Inc. and/or its wholly owned subsidiaries owned 61,856 shares of the Investor Class, representing less than 1% of the fund's net assets. T.

A copy of this code of ethics is filed as an exhibit to this Form N-CSR. No substantive amendments were approved or waivers were granted to this code of ethics during the period covered by this report. Item 3. Audit Committee Financial Expert. The registrant's Board of Directors/Trustees has determined that Mr. David K. Fagin qualifies as an audit committee financial expert, as defined in Item 3 of Form N-CSR. Mr. Fagin is considered independent for purposes of Item 3 of Form N-CSR. Item 4. Principal Accountant Fees and Services. (a) - (d) Aggregate fees billed to the registrant for the last two fiscal years for professional services rendered by the registrant's principal accountant were as follows: 2004 2003 Audit Fees $15,929 $18,187 Audit-Related Fees 2,190 1,084 Tax Fees 6,440 4,723 All Other Fees - 124 Audit fees include amounts related to the audit of the registrant's annual financial statements and services normally provided by the accountant in connection with statutory and regulatory filings. Audit-related fees include amounts reasonably related to the performance of the audit of the registrant's financial statements, specifically the issuance of a report on internal controls. Tax fees include amounts related to tax compliance, tax planning, and tax advice. 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.
