Notes to Financial Statements
T. Rowe Price Equity Income Portfolio
Certified Semiannual Report
June 30, 2004 (Unaudited)


Note 1 - Significant Accounting Policies

T. Rowe Price Equity Series, Inc. (the corporation) is registered under the
Investment Company Act of 1940 (the 1940 Act). The Equity Income Portfolio (the
fund) is a diversified, open-end management investment company and is one
portfolio established by the corporation. The fund seeks to provide substantial
dividend income as well as long-term growth of capital through investments in
the common stocks of established companies. Shares of the fund are currently
offered only through certain insurance companies as an investment medium for
both variable annuity contracts and variable life insurance policies. The fund
has two classes of shares: the Equity Income Portfolio original share class
(Equity Income Class), offered since March 31, 1994, and Equity Income
Portfolio-II (Equity Income-II class), offered since April 30, 2002. Equity
Income-II shares are sold through financial intermediaries, which it compensates
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 sales price for
international securities.

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 valued
at amortized cost in local currency, which approximates fair value when combined
with accrued interest.

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.

Class Accounting
Equity Income-II 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. Management and
administrative fee expenses, 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
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.

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. 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 a quarterly 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

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.

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 June 30, 2004, there were no securities on
loan.

Other
Purchases and sales of portfolio securities, other than short-term securities,
aggregated $165,665,000 and $96,406,000, 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.

At June 30, 2004, the cost of investments for federal income tax purposes was
$1,085,982,000. Net unrealized gain aggregated $141,569,000 at period-end, of
which $201,014,000 related to appreciated investments and $59,445,000 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
