NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

T. Rowe Price Global 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 and commenced operations on September 29, 2000.
The fund seeks to provide long-term capital growth.

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 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.

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 $12,000 for the
six months ended June 30, 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 on an annual basis.
Capital gain distributions, if any, are declared and paid by the fund, typically
on an annual basis.



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

Purchases and sales of portfolio securities, other than short-term securities,
aggregated $53,776,000 and $55,959,000, respectively, for the six months ended
June 30, 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 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 June
30, 2004.

The fund intends to retain realized gains to the extent of available capital
loss carryforwards. As of December 31, 2003, the fund had $99,760,000 of unused
capital loss carryforwards, of which $66,178,000 expire in 2009 and $33,582,000
expire in 2010.

At June 30, 2004, the cost of investments for federal income tax purposes was
$77,087,000. Net unrealized gain aggregated $12,194,000 at period-end, of which
$13,866,000 related to appreciated investments and $1,672,000 related to
depreciated investments.





NOTE 4 - FOREIGN TAXES

The fund is subject to foreign income taxes imposed by certain countries in
which it invests. Foreign income taxes are accrued by the fund as a reduction of
income.

NOTE 5 - 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 0.45% 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 June 30, 2004,
the effective annual group fee rate was 0.31%, and investment management fee
payable totaled $56,000.

The fund is also subject to a contractual expense limitation through April 30,
2005. 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 1.50%. Through April 30, 2007, 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. Pursuant to this agreement, at June 30, 2004,
management fees waived remain subject to repayment by the fund in the following
amounts: $370,000 through December 31, 2004, and $131,000 through April 30,
2007.

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 $197,000 for
the six months ended June 30, 2004, of which $38,000 was payable at
period-end.

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 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 six months ended June 30, 2004,
dividend income from the Reserve Funds totaled $1,000.
