                       Annual Investment Adviser's Report



     Concerns about Asia's economic woes were exacerbated in the first two
quarters of 1998, as signs of recession also spread to Russia, Latin America and
South America. The consequences of this worldwide slowdown were evidenced by
plummeting market capitalizations, particularly in August, for example, when
the DJIA fell 17% in four weeks. Adding to the market's problems were the
investigation of President Clinton and Russia's currency devaluation and delay
in naming a new Prime Minister. The net effect of this global turmoil was a
dramatic flight to the quality and safety of U.S. Treasury obligations. Yields
on longer-term Treasuries fell almost 40 basis points to 5.20%, while
three-month Treasury bills dropped below 4.90%. These sudden moves precipitated
widespread expectations of a reduction in the federal funds rate. In not
changing rates to date, the Fed has been particularly comforted by the positive
news on inflation. For the year-to-date, wholesale prices were down almost 1%,
while consumer prices were up only 1.5%. The Fed next meets at the end of
September and there is growing sentiment for a rate cut.

     During the last two quarters, the federal funds rate remained at 5.50%, a
level not changed since March, 1997. The short-term yield curve remained very
flat, with interest rate spreads narrowing through the month of August. Treasury
bills continued as a haven for short-term cash and yields dropped sharply near
the end of the period. In fact, the short Treasury curve inverted, with the
three-month bills yielding more than the year bill. Throughout the period,
overnight rates traded close to the federal funds level of 5.50%. Investment
strategy sought to gradually extend the Money Market Portfolio's average
maturity, as the likelihood of higher rates evaporated. Three to six-month
investments were made at yields of 5.60-5.70% during periods of market weakness,
while liquidity was maintained in repurchase agreements at yields near 5.50%. At
the end of August, the Money Market Portfolio had assets of $2,315,558,300.

     In the short-term tax-exempt market, interest rates also traded in a narrow
band during the period. One-year notes remained generally in the 3.60-3.70%
range, while shorter-term variable rate demand notes fluctuated from highs near
4.50% to lows of 2.0%. During the April tax period, the tax-free portfolios
maintained high levels of liquidity to meet possible redemptions. Average
maturities were also kept moderately short in June as the maturity of general
market notes reduced supply. In July and August, the portfolios began to extend
slightly as new issuance returned to the market. At the end of August, the
Municipal Money Market Portfolio had assets of $245,170,814.

                        Report of Independent Accountants



To the Shareholders and Board of Directors of The RBB Fund, Inc.:

In our opinion, the accompanying statements of net assets of the Money Market
and Municipal Money Market Portfolios of The RBB Fund, Inc. ("the Fund"), and
the related statements of operations and changes in net assets, and the
financial highlights present fairly, in all material respects, the financial
position of the Money Market and Municipal Money market Portfolios of The RBB
Fund, Inc. at August 31, 1998, the results of their operations for the year then
ended, changes in their net assets for each of the two years in the period then
ended, and the financial highlights for each of the periods presented, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with generally
accepted auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities owned at August 31, 1998 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

                          Notes to Financial Statements
                                 August 31, 1998



Note 1. Summary of Significant Accounting Policies

   The RBB Fund, Inc. (the "Fund") is registered under the Investment Company
Act of 1940, as amended, as an open-end management investment company. The Fund
was incorporated in Maryland on February 29, 1988.

   The Fund has authorized capital of thirty billion shares of common stock of
which 16.27 billion shares are currently classified into ninety-seven classes.
Each class represents an interest in one of twenty-six investment portfolios of
the Fund. The classes have been grouped into fifteen separate "families", nine
of which have begun investment operations: the RBB Family, the BEA Family, the
Sansom Street Family, the Bedford Family, the Cash Preservation Family, the
Janney Montgomery Scott Money Family, the n/i Family, the Schneider Family, the
Boston Partners Family, and the Schneider Capital Management Family. The Cash
Preservation Family represents interests in two portfolios, which are covered in
this report.

         A) SECURITY VALUATION -- Portfolio securities are valued under the
   amortized cost method, which approximates current market value. Under this
   method, securities are valued at cost when purchased and thereafter a
   constant proportionate amortization of any discount or premium is recorded
   until maturity of the security. Regular review and monitoring of the
   valuation is performed in an attempt to avoid dilution or other unfair
   results to shareholders. The Fund seeks to maintain net asset value per share
   at $1.00 for these portfolios.

         B) SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions
   are accounted for on the trade date. The cost of investments sold is
   determined by use of the specific identification method for both financial
   reporting and income tax purposes. Interest income is recorded on the accrual
   basis. Certain expenses, principally distribution, transfer agency and
   printing, are class specific expenses and vary by class. Expenses not
   directly attributable to a specific portfolio or class are allocated among
   all of the portfolios or classes of the Fund based on relative net assets of
   each portfolio.

         C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net
   investment income are declared daily and paid monthly. Any net realized
   capital gains will be distributed at least annually. Income distributions and
   capital gain distributions are determined in accordance with income tax
   regulations which may differ from generally accepted accounting principles.

         D) FEDERAL INCOME TAXES -- No provision is made for Federal taxes as it
   is the Fund's intention to have each portfolio continue to qualify for and
   elect the tax treatment applicable to regulated investment companies under
   the Internal Revenue Code and make the requisite distributions to its
   shareholders which will be sufficient to relieve it from Federal income and
   excise taxes.

         E) REPURCHASE AGREEMENTS -- Money market instruments may be purchased
   subject to the seller's agreement to repurchase them at an agreed upon date
   and price. The seller will be required on a daily basis to maintain the value
   of the securities subject to the agreement at not less than the repurchase
   price plus accrued interest. If the value of the underlying securities falls
   below 102% of the value of the purchase price plus accrued interest, the Fund
   will require the seller to deposit additional collateral by the next Fund
   business day. In the event that the seller under the agreement defaults on
   its repurchase obligation or fails to deposit sufficient collateral, the Fund
   has the contractual right, subject to the requirements of applicable
   bankruptcy and insolvency laws, to sell the underlying securities and may
   claim any resulting loss from the seller. The agreements are conditioned upon
   the collateral being deposited under the Federal Reserve book-entry system or
   with the Fund's custodian or a third party sub-custodian.

         F) USE OF ESTIMATES -- The preparation of financial statements in
   conformity with generally accepted accounting principles requires management
   to make estimates and assumptions that affect the reported amounts of assets
   and liabilities and disclosure of contingent assets and liabilities at the
   date of the financial statements and the reported amounts of revenues and
   expenses during the reporting period. Actual results could differ from those
   estimates.

Note 2. Transactions with Affiliates and Related Parties

   In March 1998, PNC Institutional Management Corporation, which changed its
name to BlackRock Institutional Management Corporation ("BMIC"), assumed the
responsibilities of PNC Bank, as subadviser, to provide research, credit
analysis and recommendations with respect to the Fund's investments and supply
certain computer facilities, personnel and other services. The personnel and
facilities related to these services are being transferred to BMIC and BMIC's
obligation to pay to PNC Bank a portion of the advisory fee has been terminated.

   For its advisory services, BIMC is entitled to receive the following fees,
computed daily and payable monthly based on each of the two portfolios' average
daily net assets:

                                          .35% of net assets in excess of $500 million.

    Municipal Money Market Portfolio      .35% of first $250 million of net assets; 
                                          .30% of next $250 million of net assets; 
                                          .25% of net assets in excess of $500 million.
</TABLE>

   BIMC may, at its discretion, voluntarily waive all or any portion of its
advisory fee for these portfolios. For each class of shares within a respective
portfolio, the net advisory fee charged to each class is the same on a relative
basis. For the year ended August 31, 1998, advisory fees and waivers for each of
the two investment portfolios were as follows:

   The investment advisor has agreed to reimburse each portfolio for the amount,
if any, by which the total operating and management expenses exceed the cap. For
the year ended August 31, 1998, the reimbursed expenses were $692,630, $55,085
and $392,949 for the Money Market Portfolio, Municipal Money Market Portfolio,
Government Obligations Money Market Portfolio, respectively.

   In addition, PNC Bank serves as custodian for each of the Fund's portfolios.
PFPC Inc. ("PFPC"), an indirect wholly owned subsidiary of PNC Bank Corp.,
serves as each class's transfer and dividend disbursing agent.

   PFPC may, at its discretion, voluntarily waive all or any portion of its
transfer agency fee for any class of shares. For the year ended August 31, 1998,
transfer agency fees and waivers for each class of shares within the two
investment portfolios were as follows:

                                   (Unaudited)

In the twelve months ended August 31, 1998 (the end of the Fund's fiscal year),
100% of the dividends paid by the Municipal Money Market and New York Municipal
Money Market Portfolios were exempt-interest dividends for purposes of federal
income taxes and free from such taxes. However, approximately 45% and 18% of
such dividends was attributable to interest on private activity bonds which must
be included in federal alternative minimum taxable income for the purpose of
determining liability for federal alternative minimum tax.

In January 1999, you will be furnished with a schedule showing the yearly
percentage breakdown by state or U.S. possession of the source of interest
earned by the Municipal Money Market and New York Municipal Money Market
Portfolios in 1998. It is suggested that you consult your tax adviser concerning
the applicability of state and local taxes to dividends paid by the Fund during
the year.
