Science & Technology Fund
. The broad stock market produced another strong return during the first
half, led once again by brand-name, large-capitalization, blue chip
companies.
. Science and technology stocks posted attractive results, despite heightened
volatility.
. Your fund delivered a robust performance over the last six months, roughly
in line with its peer group but trailing it for the year.
. We kept the portfolio concentrated in electronic technology stocks but
expanded both the number of holdings and their market capitalizations.
. We believe circumstances are developing that will favor continued
appreciation in technology stock prices as we move into and through 1999.

Fellow Shareholders
The stock market turned in another powerful performance during the first half of
1998. Technology stocks rallied strongly at the end of the second quarter,
enabling the fund to post results only slightly behind the broad market
averages. During the past 12 months, however, your fund lagged the S&P 500,
since technology shares were weak in 1997.

During the first half of the year, your fund returned 16.32%, compared with
17.46% for the Lipper Science & Technology Fund Index and 17.71% for the
unmanaged Standard & Poor's 500 Stock Index. For the past 12 months, the fund's
15.36% return trailed both the Lipper index of similar funds and the S&P 500.
Science and technology stocks were weaker overall than the broad market over the
year, while our exposure to some underperforming segments of the industry hurt
results slightly relative to the peer group.
We would like to remind shareholders once again that, while the fund may exhibit
short-term volatility, it has the potential for attractive long-term results.
For example, its average annual return for the 10 years ended June 30, 1998, is
22.67% compared with 19.69% for its peer group average and 18.56% for the S&P
500. (See page 9 for more performance information.)
MARKET ENVIRONMENT
The equity markets scaled a wall of worry during the first six months of the
year. Despite concern over decelerating corporate earnings growth, sporadic
fears about the near-term direction of interest rates, and spreading problems
from Asia, many global stock markets hit record high levels in the first half of
1998. Reaching ever-higher
1
<PAGE>
valuation levels, the S&P 500 bounded to its fourteenth consecutive quarter of
positive returns, with stocks of larger-capitalization, blue chip companies
continuing to outperform the rest of the market.
After a quick decline to start the year, technology stocks recovered sharply
through the end of March before moving sideways over the next few months.
Concern about the economic and currency crises in Asia; slowing growth in the
personal computer, semiconductor, and data networking industries; and the
financial drag of a stronger dollar quickly gave way to optimism regarding a
product cycle-led recovery in the second half of 1998. Performance within the
technology segment was heavily influenced by exposure to Asia and to the
inventory correction occurring in the personal computer supply chain.
Accordingly, stocks of semiconductor capital equipment, components, and
semiconductors fared the worst. In contrast, stocks of Internet-related
companies were, by far, the best-performing segment.
The PC industry remains in a product cycle lull due to the absence of
breakthrough operating system enhancements and novel applications. Without new
power-consuming software, upgrade cycles are lengthening and buyers are choosing
cheaper PCs. These trends are negatively affecting both unit growth and average
selling prices. Although pricing pressure is more intense across most segments
of the technology sector, average selling prices in the PC, data networking, and
semiconductor industries are declining at accelerating rates. The lack of new
product cycles, encroaching competition, and excess supply are all at work here.
Moreover, most of the major PC hardware original equipment manufacturers and
some of the larger telecommunications and data networking companies are
implementing policies to enhance

inventory turnover and improve their cash cycles. While these measures are
positive in the long run, they are depressing near-term revenue growth and
profit margins. Finally, the economic and currency crises in Asia should not be
underestimated. Asia (including Japan) accounts for approximately 20% to 25% of
worldwide technology consumption, including 25% of personal computer purchases,
30% of net cellular subscriber additions, and 40% of worldwide semiconductor
capital equipment demand. While it is difficult to assess the precise impact of
these crises, turmoil in this region is undoubtedly reducing the near-term
growth rate of worldwide technology spending and exacerbating the sector's
already fragile pricing environment.
INVESTMENT PHILOSOPHY
The salient characteristic of our approach is intensive, timely, hands-on
research in the areas of electronic technology, information services, life
sciences and health care, and media and telecommunications services. This
involves extensive company visits, customer and competitor interviews,
participation at trade shows and industry symposiums, and detailed financial
analysis. We focus our internal resources on developing insights, relying on
external resources primarily for information. Given the inherent volatility of
the fund's universe, we usually maintain a modest cash position to permit
opportunistic purchases.
Our investment philosophy can be summarized by the following investment
principles:
. Stay exposed to long-term, secular investment themes.
. Diversify exposure among the most attractive segments of the science and
technology sector.
. Seek investments in companies that possess significant intellectual
property.
. Concentrate holdings in companies with sustainable business models.
. Gravitate toward companies embarking on meaningful new product cycles.
. Emphasize companies whose management has both vision and a proven track
record.
. Keep the portfolio fresh.
3
<PAGE>
- --------------------------------------------------------------------------------
. . . WE HOPE TO ENSURE THAT YOUR FUND REMAINS EXPOSED TO THE BEST-POSITIONED
COMPANIES IN THE MOST RAPIDLY GROWING AREAS OF THE SCIENCE AND TECHNOLOGY
INDUSTRY.
- --------------------------------------------------------------------------------
These principles have important ramifications for your fund. First, our stock
holdings will be concentrated in the secular themes. While individual stock
holdings will change frequently, the themes should be more enduring. Second, in
contrast to most technology sector funds, our investments will be spread across
a variety of segments within a broadly defined science and technology sector.
Third, the fund will not emphasize stocks of companies selling commodity
products in highly cyclical markets. Fourth, we prefer companies whose destiny
remains more in their own control rather than the vagaries of their markets.
Fifth, our core holdings will be in stocks of companies with, in our opinion,
extremely capable management. Finally, in addition to maintaining core positions
in established, leadership companies, our holdings will include investments
across an array of smaller, more volatile companies.
By consistently applying these investment principles to the portfolio management
process, we hope to ensure that your fund remains exposed to the best-positioned
companies in the most rapidly growing areas of the science and technology
industry. Our investment approach is aggressive, and the potential long-term
rewards from an investment in this fund are likely to entail considerable price
fluctuations. However, we firmly believe that over time the rewards will
compensate for the risks. While the fund's scale and diversification make it
unlikely to be the top performer in any particular quarter, we manage the fund
to be in the hunt every year, with our primary objective being the generation of
consistent absolute and superior relative performance over a longer-term
horizon.
PORTFOLIO REVIEW
The fund remained concentrated in the electronic technology segment, with 75% of
assets committed to this area, as shown in the chart on the next page. Stocks of
software, communications, and semiconductor-related companies continued to
dominate our holdings in this segment. Shares of information services companies
represented 15% of total assets, with media and telecommunications services
composing most of the balance. At the end of the period,

reserves and other stood at 5% of fund assets.
During the past six months, fund performance was helped most by our holdings in
the enterprise software, communications equipment, and electronic commerce
segments. In the strong enterprise software segment, Microsoft, systems
management utilities vendor BMC Software, and security software vendor Network
Associates were key contributors during the period. Ascend Communications and
Cisco Systems gained as investors sought companies poised to participate in the
construction of broadband data networks. America Online benefited from strong
subscriber growth, improving profitability, and investors' manic appetite for
Internet-related stocks.
While the fund suffered from exposure to the depressed cyclical semiconductor
and peripherals segments, most of the disappointments were due to
company-specific earnings shortfalls. First Data suffered from a series of
modest earnings disappointments due to softness in its core credit card
processing business, while Adaptec fell victim to the severe downturn in the
disk drive industry. Electronics for Imaging, Xilinx, Altera, Lam Research, and
KLA-Tencor all caught a bad case of Asian flu and hurt performance over the
12-month period. Security Dynamics Technologies spent a good deal of time
stumbling over a series of new product releases and acquisitions.
OUTLOOK
While we remain cautious about the very near term, we believe circumstances are
aligning that could create an environment favoring continued appreciation in
technology stock prices as we move into and through 1999. The technology sector
underperformed the S&P 500 for the past three years as revenue growth and
earnings momentum slowed, but fundamentals in many of the more cyclical segments
of the
5
<PAGE>
technology sector may be bottoming. Comparisons with recent results in Japan and
the rest of Asia should improve, and we expect the inventory correction
afflicting the technology sector to play out at the end of 1998 or early 1999.
Finally, investor sentiment is becoming bearish while relative valuations are
increasingly attractive. Hence, looking toward 1999, we believe there is a good
chance that at least a few of the negative factors depressing the sector will be
reversed over the next few quarters, which could accelerate revenue and earnings
growth, improve sentiment, and expand sector valuations.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES
T. Rowe Price Science and Technology Fund, Inc. (the fund) is registered
under the Investment Company Act of 1940 as a diversified, open-end
management investment company and commenced operations on September 30,
1987.
The accompanying financial statements are prepared in accordance with
generally accepted accounting principles for the investment company
industry; these principles may require the use of estimates by fund
management.
Valuation Equity securities listed or regularly traded on a securities
exchange are valued at the last quoted sales price on the day the
valuations are made. A security which 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 and securities regularly traded in the over-the-counter
market are valued at the mean of the latest bid and asked prices. Other
equity securities are valued at a price within the limits of the latest bid
and asked prices deemed by the Board of Directors, or by persons delegated
by the Board, best to reflect fair value.
Investments in mutual funds are valued at the closing net asset value per
share of the mutual fund on the day of valuation.
For purposes of determining the fund's net asset value per share, the U.S.
dollar value of all assets and liabilities initially expressed in foreign
currencies is determined by using the mean of the bid and offer prices of
such currencies against U.S. dollars quoted by a major bank.
Assets and liabilities 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 or under the supervision of the
officers of the fund, as authorized by the Board of Directors.
Affiliated Companies As defined by the Investment Company Act of 1940, an
affiliated company is one in which the fund owns at least 5% of the
outstanding voting securities.
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. Dividend income and
distributions to shareholders are recorded by the fund on the ex-dividend
date. Income and
19

capital gain distributions are determined in accordance with federal income
tax regulations and may differ from those determined in accordance with
generally accepted accounting principles.
NOTE 2 - INVESTMENT TRANSACTIONS
Purchases and sales of portfolio securities, other than short-term
securities, aggregated $2,018,649,000 and $2,159,943,000, respectively, for
the six months ended June 30, 1998.
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 and distribute all of
its taxable income.
At June 30, 1998, the aggregate cost of investments for federal income tax
and financial reporting purposes was $3,282,545,000, and net unrealized
gain aggregated $694,219,000, of which $837,248,000 related to appreciated
investments and $143,029,000 to depreciated investments.
NOTE 4 - RELATED PARTY TRANSACTIONS
The investment management agreement between the fund and T. Rowe Price
Associates, Inc. (the manager) provides for an annual investment management
fee, of which $2,052,000 was payable at June 30, 1998. The fee is computed
daily and paid monthly, and consists of an individual fund fee equal to
0.35% of average daily net assets and a group fee. The group fee is based
on the combined assets of certain mutual funds sponsored by the manager or
Rowe Price-Fleming International, Inc. (the group). The group fee rate
ranges from 0.48% for the first $1 billion of assets to 0.30% for assets in
excess of $80 billion. At June 30, 1998, and for the six months then ended,
the effective annual group fee rate was 0.32%. The fund pays a pro-rata
share of the group fee based on the ratio of its net assets to those of the
group.
In addition, the fund has entered into agreements with the manager and two
wholly owned subsidiaries of the manager, pursuant to which the fund
receives certain other services. The manager computes the daily share price
and main

expenses pursuant to these related party agreements totaling approximately
$3,749,000 for the six months ended June 30, 1998, of which $775,000 was
payable at period-end.

Investment Fund (collectively, the Reserve Funds), open-end management
investment companies managed by T. Rowe Price Associates, Inc. The Reserve
Funds are offered as cash management options only to mutual funds and other
accounts managed by T. Rowe Price and its affiliates and are not available
to the public. The Reserve Funds pay no investment management fees.
