Notes to Financial Statements
T. Rowe Price Blue Chip Growth Portfolio
Certified Financials
June 30, 2003 (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 Blue Chip Growth Portfolio
(the fund) is a diversified, open-end management investment company and is one
of the portfolios established by the corporation. The fund seeks to provide
long-term capital growth. Income is a secondary objective. 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: Blue Chip Growth Portfolio, offered since
December 29, 2000, and Blue Chip Growth Portfolio-II, offered since April 30,
2002. Blue Chip Growth Portfolio-II sells its shares only through financial
intermediaries, which it compensates for distribution and 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
Investments are valued 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 official
closing price for certain markets, at the time the valuations are made. 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 ask prices for domestic securities and the last quoted sale price
for international securities.

Investments in mutual funds are valued at the closing net asset value per share
of the mutual fund 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 or under the supervision of the officers of the
fund, as authorized by the Board of Directors.

Most foreign markets close before the NYSE. Develop-ments that could affect the
values of securities that occur between the close of a foreign market and the
close of the NYSE normally will not be reflected in security valuations.
However, if such developments are so significant that they will, in the judgment
of the officers of the fund, clearly and materially affect the value of
securities, the previous closing prices may be adjusted to reflect the fair
value of the securities as of the close of the NYSE, as determined in good faith
by or under the supervision of the officers of the fund, as authorized by the
Board of Directors.

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 ask 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 such gains and losses.

Class Accounting
Blue Chip Growth Portfolio-II pays distribution and administrative expenses in
the form of Rule 12b-1 fees, in an amount not exceeding 0.25% of the class's
average net assets. Management and administrative fee expense, investment
income, and realized and unrealized gains and losses are allocated to the
classes based upon the relative daily net assets of each class. Income
distributions are declared and paid by each class on annual basis.

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.

Note 2 - Investment Transactions

Purchases and sales of portfolio securities, other than short-term securities,
aggregated $5,950,000 and $1,513,000, respectively, for the six months ended
June 30, 2003.




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 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. Temporary differences are not adjusted. 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, 2003.

For tax purposes, the fund has elected to treat net capital losses realized
between November 1 and December 31 of each year as occurring on the first day of
the following tax year; consequently, $50,000 of realized losses recognized for
financial reporting purposes in the year ended December 31, 2002 were recognized
for tax purposes on January 1, 2003. Further, the fund intends to retain
realized gains to the extent of available capital loss carryforwards. As of
December 31, 2002, the fund had $943,000 of unused capital loss carryforwards,
of which $452,000 expire in 2009, and $491,000 expire in 2010.

At June 30, 2003, the cost of investments for federal income tax purposes was
$12,576,000. Net unrealized gain aggregated $649,000 at period-end, of which
$1,014,000 related to appreciated investments and $365,000 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
investment management and administrative agreement between the fund and the
manager provides for an all-inclusive annual fee equal to 0.85% of the fund's
average daily net assets. The fee is computed daily and paid monthly. The
agreement provides that investment management, shareholder servicing, transfer
agency, accounting, and custody services are provided to the fund, and interest,
taxes, brokerage commissions, directors' fees and expenses, and extraordinary
expenses are paid directly by the fund. At June 30, 2003, $13,000 was payable
under the agreement.

The fund may invest in the T. Rowe Price Reserve Investment Fund and 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 only to mutual funds,
trusts, and other accounts managed by Price Associates and/or its affiliates,
and are not available to the public. The Reserve Funds pay no investment
management fees. Distributions from the Reserve Funds to the fund for the six
months ended June 30, 2003, totaled $2,000.
