REPORT HIGHLIGHTS
================================================================================
MID-CAP GROWTH FUND
-------------------
*    Amid  extreme  volatility  in the  first  half  and a steep  correction  in
     technology stocks, mid-caps outperformed large- and small-caps.
*    The fund  posted a modest  advance  in the six  months  ended  June 30, but
     lagged its  benchmarks.  The solid 12-month gain exceeded one benchmark but
     trailed two others.
*    Valuations in many sectors  remain  stretched,  but investors have at least
     returned to  fundamentals  following  rampant  speculation in late 1999 and
     early 2000.
*    Several  promising  sectors  -- and  mid-cap  stocks  in  general  -- offer
     excellent growth potential at reasonable  valuations,  which bodes well for
     the Mid-Cap Growth Fund.

     Stocks were  extremely  volatile in the first half of 2000, and most market
indices declined despite a powerful rebound late in the period. The signal event
was a 37%  correction in the  tech-heavy  Nasdaq  Composite in early spring that
resulted in the near destruction of many small- and mid-capitalization  Internet
companies.  After trailing  large-caps  for several  years,  mid-cap stocks were
strong  performers  during the period,  led by the technology and  biotechnology
sectors.

<PAGE>

     The Mid-Cap Growth Fund's 5.76%  first-half  ret urn, while  respectable in
absolute terms,  lagged its benchmarks for the period. Our gain of 17.65% in the
12 months ended June 30 exceeded the Standard & Poor's  MidCap Index but trailed
the Russell Midcap Growth Index and our Lipper category. Results in both periods
were  affected by our lower  weighting in  technology  stocks  compared with the
benchmarks as well as our more valuation-sensitive approach. June 30 marked your
fund's eighth  birthday,  and over that time the fund has gained 424.30% (for an
average annual return of 23.01%),  versus 292.09% for the S&P MidCap Index.  For
the past five years,  the fund has delivered an average annual return of 22.90%,
compared with 21.18% for the S&P MidCap Index.

MARKET ENVIRONMENT
------------------

     In the midst of an economic  expansion  that has  shattered all records for
duration,  U.S.  economic  growth  actually  accelerated in the first quarter of
2000. The Federal  Reserve,  which had raised  short-term rates three times last
year,  raised the ante  three more times in the first half of 2000,  capped by a
half-point move on May 16. Finally, by late May, the economy began to show signs
of responding to the Fed's strong medicine. Retail sales were sluggish, consumer
confidence  dipped  slightly,  and job creation and  industrial  demand  slowed.
Despite  anecdotal  evidence of wage  inflation  and a sharp  increase in energy
prices,  the government's price measures continued to show only slight increases
over 1999. The economy's  robust growth has helped generate  increasingly  large
federal  government  budget  surpluses,  a  situation  most would  have  thought
impossible  just a few years  ago,  and some are even  predicting  that the U.S.
government  could  be  debt-free  in a  decade.  Fixed-income  investors  nearly
panicked  at the  prospect of a looming  "shortage"  of 30-year  Treasury  bonds
resulting from reduced  federal  borrowing and the initiation of a Treasury debt
buyback.

*****************************
 . . .  Technology  stocks
bounced  back  quickly in
June . . . But most of the
dot-coms . . . have not
recovered . . .
*****************************

     In the first quarter, the stock market, like the economy,  proved amazingly
resilient in the face of generally rising interest rates.  Powerful  momentum --
and rabid speculation -- carried over from late 1999.  Valuations of the favored
technology,  Internet,  biotech,  and telecom stocks reached  historically  high
levels by the time the Nasdaq  Composite peaked above 5000 on March 10. However,
market  volatility  was  also  extreme.  During  the  first  half,  the  S&P 500
experienced  intraday price swings of 2% or more on 40% of all trading days, and
the Nasdaq  Composite  fluctuated more than 2% intraday an incredible 84% of the
time. The only comparable periods in market history were the 1930s and the 1970s
-- and stocks did not fare well overall in either  decade.  In our opinion,  the
high volatility indicates a lack of conviction on the part of investors.
<PAGE>

     A sharp  correction  -- some called it a bear market -- took hold in March,
as Internet and biotech stocks, in particular,  crashed.  Many technology stocks
bounced back quickly in June as investors  grew more  optimistic  that the Fed's
rate hikes might be nearing an end. In fact, by mid-July, after the close of our
reporting period, many biotech,  telecom,  networking,  and semiconductor stocks
had pushed back toward their highs. But most of the dot-coms, particularly those
with the  slimmest  profit  prospects,  have not  recovered.  While  many of the
biggest  winners  of 1999  and  early  2000  were  companies  with no  earnings,
investors have begun to demand profitability, though they are once again willing
to pay very high  price/earnings  (P/E)  ratios  for stocks  with  rapid  profit
growth.

     Value-oriented   shares,   such  as  those  of  retailers  and   industrial
com-panies,  had a brief  moment in the sun during the  Nasdaq  correction,  but
faded late in the period on fears of an economic slowdown. A more positive sign,
however,  is that market  breadth  improved in June as  investors  also began to
embrace more reasonably  priced,  steady growth stocks.  While large-cap  stocks
have generally  dominated the market since 1994,  small- and mid-cap shares have
taken the lead in the past year. The S&P MidCap Index's robust 8.97%  first-half
gain was nearly three times that of the Russell 2000 Index of smaller companies,
while the Dow Jones  Industrial  Average,  the S&P 500, and the Nasdaq Composite
all fell in the period.

PORTFOLIO REVIEW
----------------

     Technology,  telecom,  and health care stocks once again  dominated our top
contributors  list for the past 6- and  12-month  periods.  Both  PMC-SIERRA,  a
leader in chips  that help speed  network  communications,  and ANALOG  DEVICES,
which  specializes in  analog-to-digital  processors that are also important for
communications,  were  among our top  three  contributors  for the two  periods.
XILINX, a leader in programmable logic chips, made it into the top 10 twice.

     In health  care,  we  benefited  from  powerful  rallies  in WATERS  CORP.,
SEPRACOR, TEVA PHARMACEUTICAL  INDUSTRIES,  and AMERISOURCE HEALTH over the past
six  months.  Waters  manufactures  equipment,   including  mass  spectrometers,
necessary for drug research and development in the biotech  industry.  Investors
concluded -- correctly,  in our view -- that one way to profit from the surge of
investment in genetic research,  especially in the early stages, is to invest in
companies providing "picks and shovels" for the prospectors engaged in the human
genome gold rush. Sepracor,  by contrast,  has been mining the biotech field for
years and has struck gold in the form of a strong  pipeline of new products that
have already  begun  producing  accelerating  revenues  for the  company.  Teva,
expanding  beyond its roots as a leading  generic-drug  maker,  is  experiencing
considerable  success with the introduction of a powerful new multiple sclerosis
drug, Copaxone. Fears of Internet  disintermediation  weighed heavily on many of
the fund's holdings in late 1999 and early 2000, and none more than AmeriSource,
the  fourth-largest  drug  distributor  in  the  U.S.,  which  was  seen  to  be
particularly vulnerable. The company's stock more than doubled in the first half
as investors concluded that its business would not be imminently affected by the
Internet.  To the  best  of  our  knowledge,  pharmaceuticals  still  cannot  be
downloaded electronically!
<PAGE>

     Exceptions  to this tech and health care hegemony  included  WADDELL & REED
FINANCIAL and BJ SERVICES.  Waddell & Reed, a 1998 spin-off from Torchmark, is a
well-run  investment  manager  that is  beginning  to gain  recognition  on Wall
Street. BJ Services, which provides oil field equipment and services,  benefited
from rising energy prices and an increase in exploration activity.

    Total                         100%          100%

     The list of our worst  performers  was domi- nated by consumer and business
services stocks, such as CIBER, ROYAL CARIBBEAN CRUISES, HERTZ, and CIRCUIT CITY
STORES.   CIBER,   an  information   technology   firm,   experienced   problems
transitioning  its  revenue  base  from  packaged  applications  and  Year  2000
assignments  to Internet  enablement,  the segment  now in greatest  demand.  We
eliminated  Royal  Caribbean  Cruises as  industry  capacity  appears  likely to
outstrip demand in the intermediate  term. Hertz, the world's largest car rental
firm, continued to grow earnings,  but investors sold the stock anyway,  fearing
an economic slowdown.  We believe that Hertz's stock price discounts a much more
negative  scenario than is likely,  and we have added to our  position.  Circuit
City,  a category  killer well  positioned  to benefit from  increased  consumer
spending on all manner of digital devices,  experienced a sales slowdown in May,
causing  its stock to dive . Two  software  companies  -- Novell and  Parametric
Technology -- disappointed investors with poor earnings. We eliminated both from
the portfolio.

     We added  marginally to our technology and health care holdings,  and their
sector  weightings  rose due to strong  relative  performance.  Exposure  to the
consumer  sector fell  because of weak  performance  and sales of stocks such as
Royal Caribbean.

INVESTMENT STRATEGY AND OUTLOOK
-------------------------------
     We are  in the  midst  of a  remarkable  period  of  technological  change.
Advances   in  many   fields   --   semiconductors,   biotechnology,   genomics,
telecommunications,  and the Internet, to name just a few -- are reported daily.
The changes are so rapid that it is often unclear what is important or relevant,
even to industry  participants,  until much later. The technology revolution has
coincided with two other  phenomena that have led to a combustible  stock market
environment.  The first is a change in the  structure of markets,  which we have
discussed  at length in  earlier  letters.  The  dramatic  reduction  in trading
commissions,   driven  by  huge  advances  in  processing   and   communications
technology, has made the individual investor a greater force in the market. Even
as individuals have greatly accelerated their trading activity,  interme-diaries
such as brokers and  dealers  have  reacted to lower  commission  structures  by
reducing  the capital  devoted to their own  market-making  activities.  The net
result  is that  stock  price  movements  are  exaggerated  in both  directions.
Finally,  it is worth  noting  that  these  changes  in  technology  and  market
structure have coincided with the longest economic  expansion ever,  dulling our
collective memories of the risks inherent in the market.

*****************************
 . . .  Many  technology
companies have been driven
by momentum  strategies, and
valuations have become
divorced from the fundamentals.
*****************************


     Momentum  investing is again ascendant.  In spite of the spring correction,
technology  stocks  dominated  first-half  performance  in the  mid-cap  sector,
contributing a significant amount of the indices' return.  Virtually all of this
came from stocks with very high valuations, or without any earnings at all. Many
investors  are  buying  stocks  based  on   accelerating   earnings  per  share,
accelerating  revenues, or even accelerating increases in stock prices. This can
lead to very high valuations  that are hard to justify by traditional  measures.
While bulls rationalize high stock prices by noting the boundless  opportunities
of many of these  companies,  the recent  experience  of many dot-com  companies
should be instructive.  Price movements can suddenly reverse, and if fundamental
problems develop, stocks can fall dramatically before they find strong valuation
support.

     We have always  prided  ourselves  on being able to achieve  market-beating
returns  while  taking  below-average  risk  for a  mid-cap  growth  fund.  Risk
reduction is achieved through individual security and sector  diversification as
well as a strong bias toward buying growth at  reasonable  valuations.  Over the
long  run  this has held us in good  stead,  but in the last few  quarters,  our
valuation bias strongly  hindered  returns.  One of our benchmarks,  the Russell
Midcap  Growth  Index,  is composed  of 52%  technology  stocks,  and 26% of the
index's stocks are Internet-related, according to Prudential Securities. We have
not been able to keep  pace with this  index  while  maintaining  our  valuation
discipline  (even though our loss in the second quarter was only about half that
of the index). We do not feel it is appropriate to concentrate more than half of
our holdings in a particular sector like technology.
<PAGE>

     Some of the many newly minted  companies  will become the blue chips of the
next decade. We realize that fundamentals in the technology sector are terrific.
But from a stock  standpoint,  many  technology  companies  have been  driven by
price-momentum   strategies,  and  valuations  have  become  divorced  from  the
fundamentals.  Finding  good  companies  at  reasonable  prices  -- which is our
philosophy -- has not been a market-beating strategy.

     New  Economy  wisdom  holds  that  technology  is not  cyclical  given  the
megatrends  in  global  commerce.  However,  history  tells us that in  general,
technology, as a capital good, is indeed cyclical. Furthermore, in fast-evolving
areas where product cycles are short,  the  propensity  for technology  firms to
remain growth  companies  over an extended  period is lower than  average.  This
would argue for  lower-than-average  P/Es,  not higher,  relative to  underlying
growth rates.

          ADVISOR SHARE CLASS CREATED
          ---------------------------
          T. Rowe Price has  introduced a new class of shares for
          certain  funds,  including  this one.  The new  Advisor
          Class  shares  will be sold  exclusively  by  financial
          intermediaries, such as brokers and financial advisers,
          and will  enhance  our  ability to reach a new group of
          investors through this expanding channel. Since the new
          share class has a modest 12b-1 fee (a distribution  fee
          paid to the sales  intermediary),  its performance will
          likely vary  somewhat from your fund shares even though
          both invest in the same portfolio.

          We want to  emphasize  that the new class  will have no
          impact  whatsoever on your investment in the fund or on
          the returns  provided to you by the fund. The daily net
          asset value and expenses  for the  existing  shares and
          the Advisor Class shares are calculated separately.  In
          due course, you will see the Advisor Class share prices
          listed in  newspapers  and other  print and  electronic
          media.  Certain  expenses  associated  with the Advisor
          Class shares will be itemized in  financial  statements
          in your fund's shareholder reports.

   *************************************************************************

     In the last few  months,  a  refreshing  reality  has  returned to the high
growth  marketplace.   In  fact,  it  almost  seems  that  investors'  valuation
methodology has come full circle. A year or so ago, in an attempt to rationalize
bringing  unprofitable  dot-com  companies with unproven business models public,
investors   moved   from   analyzing   price-to-earnings   ratios   to   gauging
price-to-sales ratios. By the beginning of this year, as valuations continued to
climb and underwriting  standards fell further,  investors collectively migrated
from   price-to-sales   ratios   to  a  true   back-of-the-envelope   construct,
price-to-market opportunity. In this surreal environment, dreams seemed reality,
and economic  reason was ignored.  But in the span of six short months,  we have
returned to analyzing earnings again.  Eventually,  we are confident,  investors
will rediscover that P (price) can get too high compared with E (earnings).
<PAGE>

     Although  highly valued stocks have driven  investment  performance  in the
last year,  a large  part of the market  remains  untouched  by the  excitement.
Valuations   remain  well  above   historical   averages  in  sectors   such  as
semiconductors,  communications  equipment,  and  biotechnology,  but many other
segments,  such as business  services and telecom  services,  appear  reasonably
priced.  We have even added some new holdings in the Internet sector in the last
few months.  Mid-caps remain a segment of the market where,  on balance,  prices
are reasonable compared with earnings,  and valuations are especially attractive
compared  with  large-caps.  We believe that the Mid-Cap  Growth Fund remains an
excellent  vehicle for capitalizing on the exciting  opportunities  available in
mid-cap stocks today.

PERFORMANCE COMPARISON
----------------------
     This chart shows the value of a hypothetical $10,000 investment in the fund
over the past 10 fiscal  year  periods or since  inception  (for  funds  lacking
10-year  records).  The result is compared with benchmarks,  which may include a
broad-based  market index and a peer group average or index.  Market  indexes do
not include  expenses,  which are  deducted  from fund returns as well as mutual
fund averages and indexes.

Unaudited                                                         June 30, 2000

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------
NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES
----------------------------------------

     T. Rowe Price Mid-Cap Growth Fund, Inc. (the fund) is registered  under the
Investment Company Act of 1940 as a diversified,  open-end management investment
company.  The fund seeks long-term capital appreciation by investing in the comm
on  stocks  of  mid-cap  companies  whose  earnings  are  expected  to grow at a
faster-than-average  rate. The fund has two classes of shares -- Mid-Cap Growth,
offered since June 30, 1992, and Mid-Cap Growth Advisor Class,  first offered on
March 31,  2000.  Mid-Cap  Growth  Advisor  Class 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  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.
<PAGE>

     Investments  in mutual  funds are valued at the closing net asset value per
share of the mutual fund on the day of valuation.

     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.

     Class  Accounting The Mid-Cap Growth  Advisor Class 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.  Shareholder  servicing,
prospectus, and shareholder report expenses are charged directly to the class to
which they relate.  Expens es common to both  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  are
declared and paid by the fund on an 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.  Income  and
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.  Expenses paid indirectly reflect credits earned
on daily  uninvested  cash  balances at the custodian and are used to reduce the
fund's custody charges.

NOTE 2 - INVESTMENT TRANSACTIONS

     Purchases  and  sales  of  portfolio  securities,   other  than  short-term
securities, aggregated $1,940,454,000 and $1,695,773,000,  respectively, for the
six months ended June 30, 2000.

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, 2000, the cost of investments for federal income tax
purposes  was  substantially  the same as for  financial  reporting  and totaled
$4,521,597,000.  Net unrealized gain aggregated $1,301,250,000 at period-end, of
which  $1,715,529,000  related to appreciated  investments  and  $414,279,000 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  $3,242,000 was payable at June 30, 2000. 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 0.295%  for assets in excess of $120  billion.  At
June 30, 2000, 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.

     The manager has agreed to bear any  expenses  through  December  31,  2001,
which would cause Mid-Cap  Growth  Advisor  Class's  ratio of total  expenses to
average net assets to exceed  1.10%.  Thereafter,  through  December  31,  2003,
Mid-Cap  Growth  Advisor  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 ratio of total
expenses to average net assets to exceed 1.10%.

     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 maintains
the financial  records of the fund. T. Rowe Price  Services,  Inc. is the fund's
transfer  and  dividend   disbursing   agent  and   provides   shareholder   and
administrative  services to the fund. T. Rowe Price  Retirement  Plan  Services,
Inc. provides  subaccounting and recordkeeping  services for certain  retirement
accounts  invested in the fund.  The fund  incurred  expenses  pursuant to these
related party agreements  totaling  approximately  $3,880,000 for the six months
ended June 30, 2000, of which $696,000 was payable at period-end.

     The fund may invest in the Reserve  Investment Fund and Government  Reserve
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.  Distributions  from the
Reserve  Funds to the fund  for the six  months  ended  June 30,  2000,  totaled
$12,608,000 and are reflected as interest income in the  accompanying  Statement
of Operations.
