REPORT HIGHLIGHTS
================================================================================
PRIME RESERVE FUND
- ------------------

     *    A series of three  interest  rate hikes  during  the six months  ended
          November 30 helped boost money market yields.

     *    The Prime  Reserve  Fund  achieved  solid  performance  as its  return
          exceeded that of its Lipper peer group average.

     *    The PLUS Shares also  exceeded  the Lipper  average by a slim  margin,
          despite  the  higher  expenses   associated  with  the  shares'  added
          services.

     *    We reduced the fund's  weighted  average  maturity  as interest  rates
          rose.

     *    We are focusing on providing attractive yields.

     The U.S.  economy  continued its  remarkable  run of strong,  steady growth
during the six and 12 months ended  November  30,  1999,  and signs of inflation
were modest.  Nonetheless,  the Federal  Reserve raised the federal funds target
rate three times,  and interest rates overall rose  significantly.  Money market
funds  largely  benefited,  a trend  reflected in the  performance  of the Prime
Reserve Fund and the PLUS Shares.

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


<PAGE>

     There was little doubt during the past six months that the U.S. economy was
on solid  footing.  Annual GDP data have  painted an  attractive  picture,  with
growth  rates  fluctuating  between  3.5% and 4.5% for  nearly  four  years now.
Moreover,  the  consumer  and producer  price  indices  (CPI and PPI),  the most
commonly reported inflation figures, have generally appeared subdued. During the
past  spring  and  summer,  however,  economic  data  hinted at an  increase  in
inflationary pressure. Although economic growth did not overheat, the engines of
that growth -- including strong consumer spending fueled by rising stock markets
and home prices,  improved productivity,  and faster information flow due to the
Internet -- remained in high gear.

     [Chart showing interest rates for one-year Treasury bills,  90-day Treasury
bills, and the Federal Funds Target Rate 11/30/98 through 11/30/99.]

     Prior  to  summer,  the Fed had  largely  been  staying  on the  sidelines,
concerned that a U.S. rate hike would put untenable  pressure on fragile foreign
economies in the wake of the 1998 global currency and liquidity crisis. However,
an improving outlook overseas prompted a change in direction. The Fed raised the
federal funds target rate in June,  August,  and November by a total of 75 basis
points (100 basis points equal one percent). The target rate has returned to its
level of August 1998, just before the Fed cut rates  three-quarters of a percent
to alleviate the global financial crisis.

     The market largely  anticipated  these moves,  pushing rates sharply higher
throughout  the year.  For example,  one-year  Treasury bill yields  climbed 106
basis points to 5.65% on November 30, and other  short-term rates followed suit.
A considerable portion of those increases occurred in the last few months of the
period -- for  example,  the  one-year  rate  rose more than 40 basis  points in
October and November  alone.  Yields on money market  securities  benefited from
these changes.

    Periods Ended 11/30/99        6 Months       12 Months
    ----------------------        --------       ---------

    Prime Reserve Fund             2.36%           4.66%

    Prime Reserve PLUS Shares      2.27            4.46

    Lipper Money Market
    Funds Average                  2.26            4.43

================================================================================

     The Prime  Reserve  Fund posted good 6- and  12-month  returns of 2.36% and
4.66%,  respectively,  surpassing the 2.26% and 4.43% gains for the Lipper Money
Market  Funds  Average  by a  notable  margin.  Performance  was aided by rising
interest rates, which helped rebuild yields in our market. For the first time in
many quarters,  six-month dividends per share increased by a penny over the last
period,  contributing to a considerably  improved  seven-day  compound  dividend
yield.
<PAGE>

     The  six-month  return on the PLUS  shares of the  Prime  Reserve  Fund was
2.27%,  and its 12-month  advance was 4.46%.  These  results  also  outpaced the
benchmark averages by slim margins.  We are pleased with this result as the PLUS
shares carry a higher expense ratio, reflecting additional services available to
its investors.

     Rising  interest  rates  during the period  prompted a modest  shift in our
investment  strategy.  Earlier in the fiscal year, rates had been relatively low
and the fund's  dividend yield had slipped as a result.  As we noted in the last
shareholder report, our strategy at the time was to capture the higher yields at
the longer end of the money market  universe by maintaining an average  maturity
10 to 15 days longer than our average peer. With rates rising, however, we chose
to reduce the  portfolio's  weighted  average  maturity  from 68 days on May 31,
1999,  to a more  neutral  59 days on  November  30,  1999.  We  largely  used a
"barbell"  portfolio  structure  to achieve  the  desired  maturity  -- that is,
dividing  significant  assets  between  securities  with  one-month and one-year
maturities. As long as the possibility of rising interest rates remains high, we
will preserve an average  maturity that is generally the same as or shorter than
the average money market fund.

     We made only minor changes to the portfolio's sector positioning,  modestly
increasing  our stake in  asset-backed  securities  --  extremely  high-quality,
liquid  securities   collateralized  by  receivables  or  other  assets.   These
securities  contribute to the fund's very  high-quality  profile and also add to
the fund's diversification.

     We increased fund exposure to floating rate notes from 18% of assets at the
end of May to 31% at the end of November. Issuance of these securities increased
dramatically during the middle of the year as they became a popular form of Year
2000 financing.  The increased supply forced issuers to price offerings somewhat
more  attractively  than in the last couple of years in order to attract buyers.
Floating  rate  issues are  designed  with  adjustable  coupons  that track rate
changes relatively quickly -- a benefit to shareholders when rates are rising.

OUTLOOK
- -------

     Interest  rates could move higher in coming  months  because of  persistent
strength in the domestic economy and economic recovery  overseas.  However,  the
Fed's continued  vigilance on inflation is good news for fixed income  investors
in the long term.  Indeed,  the market  appears to us to offer  attractive  real
rates of returns  at these  levels,  and 2000 could  bring  better  results.  At
present,  we are focusing on the higher yields  available in the marketplace and
on maintaining liquidity and flexibility in the portfolio.

T. ROWE PRICE PRIME RESERVE FUND
- --------------------------------
Unaudited                                                    November 30, 1999

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

     T. Rowe Price Prime Reserve Fund,  Inc. (the fund) is registered  under the
Investment Company Act of 1940 as a diversified,  open-end management investment
company and commenced operations on March 3, 1976. Its goals are preservation of
capital,  liquidity,  and,  consistent with these,  the highest possible current
income.  The fund offers two classes of shares,  Prime Reserve and Prime Reserve
PLUS.  Prime Reserve PLUS  commenced  operations on November 1, 1998, and offers
expanded shareholder  services,  the cost of which is borne by its shareholders.
Each class has exclusive  voting rights on matters related solely to that class,
separate  voting  rights on matters  which 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  Securities are valued at amortized cost.  Assets and liabilities
for which such  valuation  procedures  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 autho rized by the Board of Directors.

     PREMIUMS AND  DISCOUNTS  Premiums  and  discounts  on debt  securities  are
amortized for both financial reporting and tax purposes.

     CLASS ACCOUNTING Shareholder servicing expenses are charged directly to the
class to which they relate. Expenses common to both classes,  investment income,
and  realized  gains and  losses are  allocated  to the  classes  based upon the
relative daily net assets of each class.  Income  distributions  are declared by
the fund on a daily basis, and paid monthly. Capital gain distributions, if any,
are declared 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.  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,  which are used to reduce the fund's
custody charges.

NOTE 2 - 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 November  30,  1999,  the cost of  investments  for  federal  income tax
purposes  was  substantially  the same as for  financial  reporting  and totaled
$5,502,957,000.

NOTE 3- 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  $1,618,000 was payable at November 30, 1999. The fee is computed daily
and paid  monthly,  and  consists  of an  individual  fund fee equal to 0.05% 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
November 30, 1999, 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 April 30, 2000,  which
would cause Prime Reserve PLUS' ratio of total expenses to average net assets to
exceed 1.00%. Thereafter, through April 30, 2002, Prime Reserve PLUS 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
with causing its ratio of total expenses to average net assets to exceed 1.00%.

     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  $4,965,000 for the six months
ended November 30, 1999, of which $1,007,000 was payable at period-end.
