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

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

     T. Rowe Price Blue Chip Growth 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 growth. Income is a secondary objective. The fund has three classes
     of shares: Blue Chip Growth (Blue Chip Growth class), offered since June
     30, 1993, Blue Chip Growth--Advisor Class (Advisor Class), offered since
     March 31, 2000, and Blue Chip Growth--R Class (R Class), offered since
     September 30, 2002). Advisor Class shares are offered only through brokers
     and other financial intermediaries, and R Class shares are only available
     to small retirement plans serviced by intermediaries. The Advisor Class and
     R Class each operate under separate Board-approved Rule 12b-1 plans,
     pursuant to which each class compensates financial intermediaries for
     distribution and certain administrative services. Each class has exclusive
     voting rights on matters related solely to that class, separate voting
     rights on matters that relate to all classes, and, in all other respects,
     the same rights and obligations as the other classes.

     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. Developments 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
     The Advisor Class and R Class each pay distribution and administrative
     expenses in the form of Rule 12b-1 fees, in an amount not exceeding 0.25%
     and 0.50%, respectively, of the class's average 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 all 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. 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.

     Expenses Paid Indirectly
     Certain security trades are directed to brokers who have agreed to rebate a
     portion of the related commission to the fund to pay fund expenses.
     Additionally, credits earned on temporarily uninvested cash balances at the
     custodian are used to reduce the fund's custody charges. Total expenses in
     the accompanying statement of operations are presented before reduction for
     rebates and credits, which totaled $274,000 and $1,000, respectively, for
     the six months ended June 30, 2003.

     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

     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 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 June 30, 2003, there were no securities on loan.

     Purchases and sales of portfolio securities, other than short-term
     securities, aggregated $1,155,270,000 and $921,670,000, 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, $62,477,000 of realized losses

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 0.30% 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 net
     assets to those of the group. At June 30, 2003, the effective annual group
     fee rate was 0.32%, and investment management fee payable totaled
     $3,063,000.

     Through December 31, 2003 for the Advisor Class and through April 30, 2004
     for the R Class, the manager is required to bear any expenses, excluding
     interest, taxes, brokerage commissions, and extraordinary expenses that
     would cause the class's ratio of total expenses to average net assets
     (expense ratio) to exceed 1.05% and 1.35%, respectively.



     Thereafter, through December 31, 2005 for the Advisor Class and through
     April 30, 2006 for the R Class, each class is required to reimburse the
     manager for these expenses, provided that its average net assets have grown
     or expenses have declined sufficiently to allow reimbursement without
     causing its expense ratio to exceed 1.05% and 1.35%, respectively. This
     agreement had no impact on the fund's total expenses during the six months
     ended June 30, 2003.

     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 Blue Chip Growth class and R
     Class. Expenses incurred pursuant to these service agreements totaled
     $6,254,000 for the six months ended June 30, 2003, of which $1,267,000 was
     payable at period-end.


     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 six months ended June 30, 2003, the Blue Chip Growth class was charged
     $213,000 for shareholder servicing costs related to the college savings
     plans, of which $170,000 was for services provided by Price and $46,000 was
     payable at period-end. At June 30, 2003, approximately 1.9% of the
     outstanding shares of the Blue Chip Growth class were held by college
     savings plans.

     The fund is also one of several mutual funds sponsored by Price Associates
     (underlying Price funds) in which the T. Rowe Price Spectrum Funds
     (Spectrum Funds) may invest. The Spectrum Funds do not invest in the
     underlying Price funds for the purpose of exercising management or control.
     Pursuant to special servicing agreements, expenses associated with the
     operation of the Spectrum Funds are borne by each underlying Price fund to
     the extent of estimated savings to it and in proportion to the average
     daily value of its shares owned by the Spectrum Funds. Expenses allocated
     under these agreements are reflected as shareholder servicing expense in
     the accompanying financial statements. For the six months ended June 30,
     2003, the Blue Chip Growth class was allocated $236,000 of Spectrum Funds'



     expenses, of which $171,000 related to services provided by Price and
     $150,000 was payable at period-end. At June 30, 2003, approximately 4.0% of
     the outstanding shares of the Blue Chip Growth class were held by the
     Spectrum Funds.

     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 $119,000.

NOTE 5 - INTERFUND BORROWING

     Pursuant to the fund's prospectus, the fund may borrow up to 33 1/3% of its
     total assets. The fund is party to an interfund borrowing agreement between
     the fund and other T. Rowe Price-sponsored mutual funds, which permits it
     to borrow or lend cash at rates beneficial to both the borrowing and
     lending funds. Loans totaling 10% or more of a borrowing fund's total
     assets are collateralized at 102% of the value of the loan; loans of less
     than 10% are unsecured. During the six months ended June 30, 2003, the fund
     had outstanding borrowings on 6 days, in the average amount of $11,200,000,
     and at an average annual rate of 1.55%. There were no borrowings
     outstanding at June 30, 2003.
