Risk/Return Summary ____________________________________________________________
                      
Investment        The Fund seeks current income with liquidity and stability
Goal:             of principal.          
         
Investment        The Fund invests in a broad range of money market
Policies:         instruments, including government, bank, and commercial
                  obligations and repurchase agreements relating to such
                  obligations.          
                     
Principal Risks   Although the Fund invests in money market instruments which
of Investing:     the investment adviser, BlackRock Institutional Management
                  Corporation ("BIMC," or the "Adviser") believes present
                  minimal credit risks at the time of purchase, there is a
                  risk that an issuer may not be able to make principal and
                  interest payments when due. While the Fund seeks to maintain
                  a constant net asset value of $1.00 per share, the Fund is
                  also subject to risks related to changes in prevailing
                  interest rates, since generally, a fixed-income security
                  will increase in value when interest rates fall and decrease
                  in value when interest rates rise.       

                  An investment in the Fund is not a deposit in PNC Bank,
                  N.A. and is not insured or guaranteed by the Federal Deposit
                  Insurance Corporation or any other government agency.
                  Although the Fund seeks to preserve the value of your
                  investment at $1.00 per share, it is possible to lose money
                  by investing in the Fund.
 
Who May Want to   The Fund is designed for institutional investors seeking
Invest in the     current income and stability of principal. The Fund is
Fund:             particularly suitable for banks, corporations and other
                  financial institutions that seek investment of short-term
                  funds for their own accounts or for the accounts of their
                  customers.

Investment
Strategies and
Risk Disclosure ________________________________________________________________
                                            
                  The Fund is a money market fund. The investment objective of
                  the Fund is to seek current income and stability of
                  principal. The Fund's investment objective may be changed by
                  the Board of Trustees without shareholder approval. The
                  Fund invests in a broad range of money market instruments,
                  including government, bank, and commercial obligations and
                  repurchase agreements relating to such obligations.          
                                           
                  The Fund invests in securities maturing within 13 months
                  or less from the date of purchase, with certain exceptions.
                  For example, certain government securities held by the Fund
                  may have remaining maturities exceeding 13 months if such
                  securities provide for adjustments in their interest rates
                  not less frequently than every 13 months. The securities
                  purchased by the Fund are also subject to the quality,
                  diversification, and other requirements of Rule 2a-7 under
                  the Investment Company Act of 1940, as amended, and other
                  rules of the Securities and Exchange Commission. Pursuant to
                  Rule 2a-7, the Fund will generally limit its purchases of
                  any one issuer's securities (other than U.S. Government
                  obligations, repurchase agreements collateralized by such
                  securities and securities subject to certain guarantees or
                  otherwise providing a right to demand payment) to 5% of the
                  Fund's total assets, except that up to 25% of its total
                  assets may be invested in securities of one issuer for a
                  period of up to three business days; provided that the Fund
                  may not invest more than 25% of its total assets in the
                  securities of more than one issuer in accordance with the
                  foregoing at any one time.          
                                            
                  The Fund will only purchase securities that present minimal
                  credit risk as determined by the Adviser pursuant to
                  guidelines approved by the Board of Trustees of Provident
                  Institutional Funds. Securities purchased by the Fund (or the
                  issuers of such securities) will be First Tier Eligible
                  Securities which are rated at the time of purchase in the
                  highest rating category by either Standard & Poor's Ratings
                  Group or Moody's Investors Services, Inc., and will be rated
                  in the highest rating category by any other nationally
                  recognized statistical rating organization ( a "NRSRO") that
                  rates such security (or its issuer).

Investments       The Fund's investments may include the following:          
 
U.S. Government   The Fund may purchase obligations issued or guaranteed by 
Obligations       the U.S. Government or its agencies and instrumentalities 
                  and related custodial receipts.                            
                  
                  
 
                                       7

Bank Obligations  The Fund may purchase obligations of issuers in the banking
                  industry, such as bank holding company obligations,
                  certificates of deposit, bankers' acceptances and bank notes
                  issued or supported by the credit of domestic banks or
                  savings institutions having total assets at the time of
                  purchase in excess of $1 billion. The Fund may also make
                  interest-bearing savings deposits in domestic commercial and
                  savings banks in amounts not in excess of 5% of the Fund's
                  assets.     
 
Commercial Paper  The Fund may invest in commercial paper, short-term notes
                  and corporate bonds of domestic corporations that meet the
                  Fund's quality and maturity requirements.
 
Asset-Backed      The Fund may invest in asset-backed securities which are  
Obligations       backed by mortgages, installment sales contracts, credit 
                  card receivables or other assets.                         
 
    
Investment        The Fund may invest in securities issued by other open-end   
Company           investment companies that invest in the type of obligations  
Securities        in which the Fund may invest and that determine their net    
                  asset value per share based upon the amortized cost or penny 
                  rounding method. Investments in the securities of other      
                  investment companies will cause the Fund (and, indirectly    
                  the Fund's shareholders) to bear proportionately the costs   
                  incurred in connection with the other investment companies'  
                  operations.                                                   
                  
Municipal         The Fund may, when deemed appropriate by the Adviser in      
Obligations       light of the Fund's investment objective, invest in high    
                  quality, short-term obligations issued by state and local   
                  governmental issuers which carry yields that are competitive
                  with those of other types of money market instruments of    
                  comparable quality.                                          
                      
Variable and      The Fund may purchase variable or floating rate notes, which 
Floating Rate     are instruments that provide for adjustments in the interest 
Instruments       rate on certain reset dates or whenever a specified interest 
                  rate index changes, respectively.                             

Repurchase        The Fund may enter into repurchase agreements. 
Agreements
                      
Reverse           The Fund may enter into reverse repurchase agreements. The 
Repurchase        Fund is permitted to invest up to one-third of its total   
Agreements and    assets in reverse repurchase agreements. The Fund may also 
Securities        lend its securities with a value of up to one-third of its 
Lending           total assets (including the value of the collateral for the
                  loan) to qualified brokers, dealers, banks and other       
                  financial institutions for the purpose of realizing        
                  additional net investment income through the receipt of    
                  interest on the loan. Investments in reverse repurchase    
                  agreements and securities lending transactions will be     
                  aggregated for purposes of this investment limitation.

When-Issued and   The Fund may purchase securities on a "when-issued" or
Delayed           "delayed settlement" basis. The Fund expects that
Settlement        commitments to purchase when-issued or delayed settlement
Transactions      securities will not exceed 25% of the value of its total
                  assets absent unusual market conditions. The Fund does not
                  intend to purchase when-issued or delayed settlement
                  securities for speculative purposes but only in furtherance
                  of its investment objective.
     
Illiquid          The Fund will not invest more than 10% of the value of its   
Securities        total assets in illiquid securities, including time deposits 
                  and repurchase agreements having maturities longer than      
                  seven days. Securities that have readily available market    
                  quotations are not deemed illiquid for purposes of this      
                  limitation.                                                   
     
Other Types of    This Prospectus describes the Fund's principal investment   
Investments       strategies, and the particular types of securities in which 
                  the Fund principally invests. The Fund may, from time to    
                  time, make other types of investments and pursue other      
                  investment strategies in support of its overall investment  
                  goal. Any other types of investments will comply with the   
                  Fund's quality and maturity guidelines. These supplemental  
                  investment strategies are described in detail in the        
                  Statement of Additional Information, which is referred to on
                  the back cover of this Prospectus.                           
                  
Risk Factors      The principal risks of investing in the Fund are also
                  described above in the Risk/Return Summary. The following
                  supplements that description.
 
Interest Rate     Generally, a fixed-income security will increase in value   
Risk              when interest rates fall and decrease in value when interest
                  rates rise. As a result, if interest rates were to change   
                  rapidly, there is a risk that the change in market value of 
                  the Fund's assets may not enable the Fund to maintain a     
                  stable net asset value of $1.00 per share.                   
                      
Credit Risk       The risk that an issuer will be unable to make principal and
                  interest payments when due is known as "credit risk." U.S.
                  Government securities are generally considered to be the
                  safest type of investment in terms of credit risk, with
                  municipal obligations and corporate debt securities
                  presenting somewhat higher credit risk. Credit quality
                  ratings published by an NRSRO are widely accepted measures
                  of credit risk. The lower a security is rated by an NRSRO,
                  the more credit risk it is considered to represent.
     
Other Risks       Certain investment strategies employed by the Fund may
                  involve additional investment risk. Liquidity risk involves
                  certain securities which may be difficult or impossible to
                  sell at the time and the price that the Fund would like.
                  Reverse repurchase agreements, securities lending
                  transactions and when-issued or delayed     
 
                                       9
<PAGE>
 
                         
                  delivery transactions may involve leverage risk. Leverage
                  risk is associated with securities or practices that
                  multiply small market movements into larger changes in the
                  value of the Fund's investment portfolio. The Fund does not
                  currently intend to employ investment strategies that
                  involve leverage risk.          
 
Year 2000         Like other mutual funds, financial and business
                  organizations and individuals around the world, the Fund
                  could be adversely affected if the computer systems used by
                  the Adviser and the Fund's other service providers, or
                  persons with whom they deal, do not properly process and
                  calculate date-related information and data from and after
                  January 1, 2000. This possibility is commonly known as the
                  "Year 2000 Problem." The Fund has been advised by the
                  Adviser, the Administrators and the Custodian that they are
                  actively taking steps to address the Year 2000 Problem with
                  respect to the computer systems that they use and to obtain
                  assurances that comparable steps are being taken by the
                  Fund's other major service providers. While there can be no
                  assurance that the Fund's service providers will be Year
                  2000 compliant, the Fund's service providers expect that
                  their plans to be compliant will be achieved.
 
Management of the Fund _________________________________________________________
        
Investment        The Adviser, a wholly-owned indirect subsidiary of PNC Bank,  
Adviser           serves as the Fund's investment adviser. The Adviser and its 
                  affiliates are one of the largest U.S. bank managers of      
                  mutual funds, with assets currently under management in      
                  excess of $46 billion. BIMC (formerly known as PNC           
                  Institutional Management Corporation or "PIMC") was          
                  organized in 1977 by PNC Bank to perform advisory services   
                  for investment companies and has its principal offices at    
                  Bellevue Park Corporate Center, 400 Bellevue Parkway,        
                  Wilmington, Delaware 19809.     
                         
                  As investment adviser, BIMC manages the Fund and is
                  responsible for all purchases and sales of the Fund's
                  securities. For the investment advisory services provided and
                  expenses assumed by it, BIMC is entitled to receive a fee,
                  computed daily and payable monthly, based on the Fund's
                  average net assets. BIMC and PFPC, the co-administrator, may
                  from time to time reduce the investment advisory and
                  administration fees otherwise payable to them or may reimburse
                  the Fund for its operating expenses. Any fees waived and any
                  expenses reimbursed by BIMC and PFPC with respect to a
                  particular fiscal year are not recoverable. For the fiscal
                  year ended September 30, 1998, the Fund paid investment
                  advisory fees and administration fees each aggregating .08%
                  (net of waivers) of its average net assets. The services
                  provided by BIMC and the fees payable by the Fund for these
                  services are described further in the Statement of Additional
                  Information under "Management of the Funds."

Shareholder Information ________________________________________________________

Price of Fund     The Fund's net asset value per share for purposes of pricing
Shares            purchase and redemption orders is determined by PFPC Inc.
                  ("PFPC"), the Funds co-administrator, as of 12:00 noon and
                  5:30 P.M., Eastern time, on each day on which both the New
                  York Stock Exchange and the Federal Reserve Bank of
                  Philadelphia are open for business (a "Business Day"). The
                  net asset value per share of each class of the Fund's shares
                  is calculated by adding the value of all securities and
                  other assets of the Fund that are allocable to a particular
                  class, subtracting liabilities charged to such class, and
                  dividing the result by the total number of outstanding
                  shares of such class. In computing net asset value, the Fund
                  uses the amortized cost method of valuation as described in
                  the Statement of Additional Information under "Additional
                  Purchase and Redemption Information." Under the 1940 Act,
                  the Fund may postpone the date of payment of any redeemable
                  security for up to seven days.
               
Purchase of       Fund shares are sold at the net asset value per share next
Shares            determined after confirmation  of a purchase order by PFPC,
                  which also serves as the Fund's transfer agent. Purchase
                  orders for shares are accepted only on Business Days and
                  must be transmitted to PFPC in Wilmington, Delaware by
                  telephone (800-441-7450; in Delaware: 302-791-5350) or
                  through the Fund's computer access program. Orders accepted
                  before 12:00 noon, Eastern time, for which payment has been
                  received by PNC Bank, N.A. ("PNC Bank"), the Fund's
                  custodian, will be executed at 12:00 noon. Orders accepted
                  after 12:00 noon and before 5:30 P.M., Eastern time (or
                  orders accepted earlier in the same day for which payment
                  has not been received by 12:00 noon), will be executed at
                  5:30 P.M., Eastern time, if payment has been received by PNC
                  Bank by that time. Orders received at other times, and
                  orders for which payment has not been received by 5:30 P.M.,
                  Eastern time, will not be accepted, and notice thereof will
                  be given to the institution placing the order. (Payment for
                  orders which are not received or accepted will be returned
                  after prompt inquiry to the sending institution.) Between
                  3:00 P.M. and 5:30 P.M., Eastern time, purchase orders may
                  only be transmitted by telephone, and the Fund reserves the
                  right to limit the amount of such orders. The Fund may in
                  its discretion reject any order for shares.          

                  Payment for Fund shares may be made only in federal funds
                  or other funds immediately available to PNC Bank. The
                  minimum initial investment by an institution is $3 million
                  for TempFund Shares; there is no minimum initial investment
                  for TempFund Administration Shares, TempFund Dollar Shares,
                  TempFund Plus Shares, TempFund Cash Reserve Shares or

                  broker-dealers and other institutional investors may set a
                  minimum for their customers. There is no minimum subsequent
                  investment. The Fund, at its discretion, may reduce the
                  minimum initial investment for TempFund Shares for specific
                  institutions whose aggregate relationship with the Provident
                  Institutional Funds is substantially equivalent to this $3
                  million minimum and warrants this reduction.
                  
                  Fund shares are sold and redeemed without charge by the
                  Fund. Institutional investors purchasing or holding Fund
                  shares for their customer accounts may charge customer fees
                  for cash management and other services provided in
                  connection with their accounts. A customer should,
                  therefore, consider the terms of its account with an
                  institution before purchasing Fund shares. An institution
                  purchasing or redeeming Fund shares on behalf of its
                  customers is responsible for transmitting orders to the Fund
                  in accordance with its customer agreements.

                  Conflict of interest restrictions may apply to an
                  institution's receipt of compensation paid by the Fund in
                  connection with the investment of fiduciary funds in
                  TempFund Administration Shares, TempFund Dollar Shares,
                  TempFund Plus Shares, TempFund Cash Reserve Shares or
                  TempFund Cash Management Shares. (See also "Management of
                  the Fund--Service Organizations," as described in the
                  Statement of Additional Information.) Institutions,
                  including banks regulated by the Comptroller of the Currency
                  and investment advisers and other money managers subject to
                  the jurisdiction of the SEC, the Department of Labor or
                  state securities commissions, are urged to consult their
                  legal advisors before investing fiduciary funds in TempFund
                  Administration Shares, TempFund Dollar Shares, TempFund Plus
                  Shares, TempFund Cash Reserve Shares or TempFund Cash
                  Management Shares. (See also "Management of the Fund--
                  Banking Laws," as described in the Statement of Additional
                  Information).
 
Redemption of     Redemption orders must be transmitted to PFPC in Wilmington,
Shares            Delaware in the manner described under "Purchase of Shares."
                  Shares are redeemed at the net asset value per share next   
                  determined after PFPC's receipt of the redemption order.    
                  Telephone instructions for redemptions received between 3:00
                  P.M. and 5:30 P.M., Eastern time, on a Business Day are     
                  received for execution on that same day, however, the Fund  
                  reserves the right to make payment for such redemptions the 
                  next Business Day. While the Fund intends to use its best   
                  efforts to maintain its net asset value per share at $1.00, 
                  the proceeds paid to a shareholder upon redemption may be   
                  more or less than the amount invested depending upon a      
                  share's net asset value at the time of redemption. Call 1-  
                  800-441-7450 (in Delaware: 302-791-5350) to place redemption
                  orders.

                  Payment for redeemed shares for which a redemption order
                  is received by PFPC by 5:30 P.M., Eastern time, on a
                  Business Day is normally made in federal funds wired to the
                  redeeming shareholder on the same day. Payment for
                  redemption orders which are received on a day when PNC Bank
                  is closed is normally wired in federal funds on the next day
                  following redemption that PNC Bank is open for business.      
    
                  The Fund shall have the right to redeem shares in any
                  account if the value of the account is less than $1,000
                  after sixty-days' prior written notice to the shareholder.
                  Any such redemption shall be effected at the net asset value
                  next determined after the redemption order is entered. If
                  during the sixty-day period the shareholder increases the
                  value of its account to $1,000 or more, no such redemption
                  shall take place. In addition, the Fund may also redeem
                  shares involuntarily under certain special circumstances
                  described in the Statement of Additional Information under
                  "Additional Purchase and Redemption Information."      
 
Distribution      The Fund offers six classes of shares. The difference      
and Shareholder   between the classes of shares is the fees borne by a class 
Service Plans     of shares pursuant to separate fees plans adopted by each  
                  class. TempFund Shares do not bear any fees for

                  Service Fees are paid for general shareholder liaison
                  services. Shareholder Service Fees are paid for services
                  relating to the processing and administration of shareholder
                  accounts. The Fund has adopted a plan pursuant to Rule 12b-
                  1. 12b-1 Fees are paid for distribution and sales support,
                  and shareholder services. Cash Sweep Fees are paid for
                  distribution and sales support, and shareholder services.
                  Cash Sweep Fees are paid for providing a sweep service into

                  Administration Shares, Dollar Shares, Cash Reserve Shares
                  and Cash Management Shares are sold to institutional
                  investors such as banks, saving and loan associations, and
                  other financial institutions, including affiliates of PNC
                  Bank Corp. ("Service Organizations"). Plus Shares are sold
                  to broker-dealers. Because fees associated with the
                  distribution and/or shareholder service plans are paid out
                  of the Fund's assets on an outgoing basis, over time holders
                  of the share classes described above may pay more than the
                  economic equivalent of the maximum front-end sales charge
                  permitted by NASD Regulation, Inc.

Dividends and     The Fund declares dividends daily and distributes             
Distributions     substantially all of its net investment income to             
                  shareholders monthly. Shares begin accruing dividends on the  
                  day the purchase order for the shares is effected and         
                  continue to accrue dividends through the day before such      
                  shares are redeemed. Dividends are paid monthly by check, or  
                  by wire transfer if requested in writing by the shareholder,  
                  within five business days after the end of the month or       
                  within five business days after a redemption of all of a      
                  shareholder's shares of a particular class.                   
    
                  Institutional shareholders may elect to have their dividends
                  reinvested in additional full and fractional shares of the
                  same class of shares with respect to which such dividends are
                  declared at the net asset value of such shares on the payment
                  date. Reinvested dividends receive the same tax treatment as
                  dividends paid in cash. Reinvestment elections, and any
                  revocations thereof, must be made in writing to PFPC, the
                  Fund's transfer agent, at P.O. Box 8950, Wilmington, Delaware
                  19885-9628 and will become effective after its receipt by PFPC
                  with respect to dividends paid.     
       
Taxes             The Fund's distributions will generally be taxable to
                  shareholders. The Fund expects that all, or substantially
                  all, of its distributions will consist of ordinary income.
                  You will be subject to income tax on these distributions
                  regardless whether they are paid in cash or reinvested in
                  additional shares.     
                         
                  PFPC, as transfer agent, will send each Fund shareholder or
                  its authorized representative an annual statement designating
                  the amount, if any, of any dividends and distributions made
                  during each year and their federal tax treatment.     
                         
                  Dividends declared in December of any year, and payable to
                  shareholders of record on a specified date in December, will
                  be deemed to have been received by the shareholders and paid
                  by the Fund on December 31 of such year in the event such
                  dividends are actually paid during January of the following
                  year.     
    
                  You should consult your tax adviser for further information
                  regarding the federal, state and local tax consequences with
                  respect to your specific situation.

Financial Highlights ___________________________________________________________
   
The financial highlights tables are intended to help you understand the Fund's
financial performance for the past 5 years. Certain information reflects
financial results for a single Fund share. The total returns in the table
represent the rate that an investor would have earned or lost on an investment
in the Fund (assuming reinvestment of all dividends and distributions). This
information has been audited by PricewaterhouseCoopers LLP, whose report, along
with the Fund's financial statements, are incorporated by reference into the
Statement of Additional Information and included in the Annual Report, each of
which is available upon request. Administration Shares, Plus Shares, Cash
Reserve Shares and Cash Management Shares of the Fund have not yet commenced
operations, therefore no financial information has been provided for these

                              RISK/RETURN SUMMARY
                                        
 
     
INVESTMENT GOAL:                The Fund seeks current income with liquidity and
                                stability of principal.     
    
INVESTMENT POLICIES:            The Fund invests in a broad range of money
                                market instruments, including government, U.S.
                                and foreign bank and commercial obligations and
                                repurchase agreements relating to such
                                obligations. Under normal market conditions, at
                                least 25% of the Fund's total assets will be
                                invested in obligations of issuers in the
                                financial services industry and repurchase
                                agreements relating to such obligations.     
    
PRINCIPAL RISKS OF INVESTING:   Although the Fund invests in money market
                                instruments which the investment adviser,
                                BlackRock Institutional Management Corporation
                                ("BIMC," or the "Adviser") believes present
                                minimal credit risks at the time of purchase,
                                there is a risk that an issuer may not be able
                                to make principal and interest payments when
                                due. While the Fund seeks to maintain a constant
                                net asset value of $1.00 per share, the Fund is
                                also subject to risks related to changes in
                                prevailing interest rates, since generally, a
                                fixed-income security will increase in value
                                when interest rates fall and decrease in value
                                when interest rates rise.     

                                Because of its concentration in the financial
                                services industry, the Fund will be exposed to
                                the risks associated with that industry, such as
                                government regulation, the availability and cost
                                of capital funds, and general economic
                                conditions. In addition, securities issued by
                                foreign entities, including foreign banks and
                                corporations may involve additional risks.
                                Examples of these risks are the lack of
                                available public information about the foreign
                                issuer, and international economic or

                                      -3-
<PAGE>
 
                                political developments which could affect the
                                payment of principal and interest when due.

                                An investment in the Fund is not a deposit in
                                PNC Bank, N.A. and is not insured or guaranteed
                                by the Federal Deposit Insurance Corporation or
                                any other government agency. Although the Fund
                                seeks to preserve the value of your investment
                                at $1.00 per share, it is possible to lose money
                                by investing in the Fund.

WHO MAY WANT TO INVEST          The Fund is designed for institutional investors
IN THE FUND:                    seeking current income and stability of
                                principal. The Fund is particularly suitable for
                                banks, corporations and other financial

                                funds for their own accounts or for the accounts
                                of their customers.

Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same.  Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                   INVESTMENT STRATEGIES AND RISK DISCLOSURE
                                            
     The Fund is a money market fund. The investment objective of the Fund is to
seek current income and stability of principal. The Fund's investment objective
may be changed by the Board of Trustees without shareholder approval. The Fund
invests in a broad range of money market instruments, including government, U.S.
and foreign bank and commercial obligations and repurchase agreements relating
to such obligations. At least 25% of the Fund's total assets will be invested in
obligations of issuers in the financial services industry and repurchase
agreements relating to such obligations, unless the Fund is in a temporary
defensive position.    
    
     The Fund invests in securities maturing within 13 months or less from the
date of purchase, with certain exceptions. For example, certain government
securities held by the Fund may have remaining maturities exceeding 13 months if
such securities provide for adjustments in their interest rates not less
frequently than every 13 months. The securities purchased by the Fund are also
subject to the quality, diversification, and other requirements of Rule 2a-7
under the Investment Company Act of 1940, as amended, and other rules of the
Securities and Exchange Commission. Pursuant to Rule 2a-7, the Fund generally
will limit its purchases of any one issuer's securities (other than U.S.
Government obligations, repurchase agreements collateralized by such securities
and securities subject to certain guarantees or otherwise providing a right to
demand payment) to 5% of the Fund's total assets, except that up to 25% of its
total assets may be invested in securities of one issuer for a period of up to
three business days; provided that the Fund may not invest more than 25% of its
total assets in the securities of more than one issuer in accordance with the
foregoing at any one time.     
    
     The Fund will only purchase securities that present minimal credit risk as
determined by the Adviser pursuant to guidelines approved by the Board of
Trustees of Provident Institutional Funds. Securities purchased by the Fund
(or the issuers of such securities) will be First Tier Eligible Securities.
First Tier Eligible Securities are:     
    
     .    securities that have ratings at the time of purchase (or which are
          guaranteed or in some cases otherwise supported by guarantees or other
          credit supports with such ratings) in the highest rating category by
          at least two unaffiliated nationally recognized statistical rating
          organizations ("NRSROs"), or one NRSRO, if the security or guarantee
          was only rated by one NRSRO;    
    
     .    securities that are issued or guaranteed by a person with such
          ratings;     
    
     .    securities without such short-term ratings that have been determined
          to be of comparable quality by the Adviser pursuant to guidelines
          approved by the Board of Trustees;     
    
     .    securities issued or guaranteed as to principal or interest by the
          U.S. Government or any of its agencies or instrumentalities; or      
    
     .    securities issued by other open-end investment Companies that invest 
          in the type of obligations in which the Fund may invest.     
    
     Investments. The Fund's investments may include the following:     

     U.S. Government Obligations.  The Fund may purchase obligations issued or
guaranteed by the U.S. Government or its agencies and instrumentalities and
related custodial receipts.

                                      -8-
<PAGE>

     
     Bank Obligations. The Fund may purchase obligations of issuers in the
banking industry, such as bank holding company obligations and certificates of
deposit, bankers' acceptances, bank notes and time deposits, including U.S. 
dollar-denominated instruments issued or supported by the credit of U.S. or
foreign banks or savings institutions having total assets at the time of
purchase in excess of $1 billion. The Fund may invest substantially in
obligations of foreign banks or foreign branches of U.S. banks where the Adviser
deems the instrument to present minimal credit risks. The Fund may also make
interest-bearing savings deposits in commercial and savings banks in amounts not
in excess of 5% of its assets.    

     Commercial Paper.  The Fund may invest in commercial paper and short-term
notes and corporate bonds that meet the Fund's quality and maturity
restrictions.  Commercial paper purchased by the Fund may include instruments
issued by foreign issuers, such as Canadian Commercial Paper, which is U.S.
dollar-denominated commercial paper issued by a Canadian corporation or a
Canadian counterpart of a U.S. corporation, and in Europaper, which is U.S.
dollar-denominated commercial paper of a foreign issuer.

     Asset-Backed Obligations.  The Fund may invest in asset-backed securities
which are backed by mortgages, installment sales contracts, credit card
receivables or other assets and collateralized mortgage obligations ("CMOs")
issued or guaranteed by U.S. Government agencies and instrumentalities or issued
by private companies.  Purchasable mortgage-related securities also include
adjustable rate securities.  The Fund currently intends to hold CMOs only as
collateral for repurchase agreements.
    
     Investment Company Securities.  The Fund may invest in securities issued by
other open-end investment companies that invest in the type of obligations in
which the Fund may invest and that determine their net asset value per share
based upon the amortized cost or penny rounding method. Investments in the 
securities of other investment companies will cause the Fund (and, indirectly 
the Fund's shareholders) to bear proportionately the costs incurred in 
connection with the other investment companies' operations.     

     Municipal Obligations.  The Fund may, when deemed appropriate by the
Adviser in light of the Fund's investment objective, invest in high quality,
short-term obligations issued by state and local governmental issuers which
carry yields that are competitive with those of other types of money market
instruments of comparable quality.

     Guaranteed Investment Contracts.  The Fund may make investments in
obligations, such as guaranteed investment contracts and similar funding
agreements (collectively "GICs"), issued by highly rated U.S. insurance
companies.  GIC investments that do not provide for payment within seven days
after notice are subject to the Fund's policy regarding investments in illiquid
securities.
    
     Variable and Floating Rate Instruments. The Fund may purchase variable or
floating rate notes, which are instruments that provide for adjustments in the
interest rate on certain reset dates or whenever a specified interest rate index
changes, respectively.     

     Repurchase Agreements.  The Fund may enter into repurchase agreements.

                                      -9-
<PAGE>

     
     Reverse Repurchase Agreements and Securities Lending.  The Fund may enter
into reverse repurchase agreements. The Fund is permitted to invest up to one-
third of its total assets in reverse repurchase agreements. The Fund may also
lend its securities with a value of up to one-third of its total assets
(including the value of the collateral for the loan) to qualified brokers,
dealers, banks and other financial institutions for the purpose of realizing
additional net investment income through the receipt of interest on the loan.
Investments in reverse repurchase agreements and securities lending transactions
will be aggregated for purposes of this investment limitation.     

     When-Issued and Delayed Settlement Transactions.  The Fund may purchase
securities on a "when-issued" or "delayed settlement" basis.  The Fund expects
that commitments to purchase when-issued or delayed settlement securities will
not exceed 25% of the value of its total assets absent unusual market
conditions.  The Fund does not intend to purchase when-issued or delayed
settlement securities for speculative purposes but only in furtherance of its
investment objective.
    
     Illiquid Securities. The Fund will not invest more than 10% of the value of
its total assets in illiquid securities, including time deposits and repurchase
agreements having maturities longer than seven days. Securities that have
readily available market quotations are not deemed illiquid for purposes of this
limitation.     
    
     Other Types of Investments. This Prospectus describes the Fund's principal
investment strategies, and the particular types of securities in which the Fund
principally invests. The Fund may, from time to time, make other types of
investments and pursue other investment strategies in support of its overall
investment goal. Any other types of investments will comply with the Fund's
quality and maturity guidelines. These supplemental investment strategies are
described in detail in the Statement of Additional Information, which is
referred to on the back cover of this Prospectus.     

     RISK FACTORS.  The principal risks of investing in the Fund are also
described above in the Risk/Return Summary. The following supplements that
description.

     Interest Rate Risk.  Generally, a fixed-income security will increase in
value when interest rates fall and decrease in value when interest rates rise.
As a result, if interest rates were to change rapidly, there is a risk that the
change in market value of the Fund's assets may not enable the Fund to maintain
a stable net asset value of $1.00 per share.
    
     Credit Risk.  The risk that an issuer will be unable to make principal and
interest payments when due is known as "credit risk." U.S. Government securities
are generally considered to be the safest type of investment in terms of credit
risk, with municipal obligations and corporate debt securities presenting
somewhat higher credit risk. Credit quality ratings published by an NRSRO are
widely accepted measures of credit risk. The lower a security is rated by an
NRSRO, the more credit risk it is considered to represent.     
    
     Other Risks. Certain investment strategies employed by the Fund may involve
additional investment risk. Liquidity risk involves certain securities which may
be difficult or impossible to sell at the time and the price that the Fund would
like. Reverse repurchase agreements, securities lending transactions and when-
issued or delayed delivery transactions may involve leverage risk.     

                                      -10-
<PAGE>
 
    
Leverage risk is associated with securities or practices that multiply small
market movements into larger changes in the value of the Fund's investment
portfolio. The fund does not currently intend to employ investment strategies 
that involve leverage risk.     

     Concentration.  The Fund intends to concentrate more than 25% of its total
assets in the obligations of issuers in the financial services industry and
repurchase agreements relating to such obligations.  Because the Fund
concentrates its assets in the financial services industry it will be exposed to
the risks associated with that industry, such as government regulation, the
availability and cost of capital funds, and general economic conditions.

     Foreign Exposure.  Securities issued by foreign entities, including foreign
banks and corporations, may involve additional risks and considerations.
Extensive public information about the foreign issuer may not be available, and
unfavorable political, economic or governmental developments in the foreign
country involved could affect the payment of principal and interest.

     Year 2000.   Like other mutual funds, financial and business organizations
and individuals around the world, the Fund could be adversely affected if the
computer systems used by the Adviser and the Fund's other service providers, or
persons with whom they deal, do not properly process and calculate date-related
information and data from and after January 1, 2000.  This possibility is
commonly known as the "Year 2000 Problem."  The Fund has been advised by the
Adviser, the Administrators and the Custodian that they are actively taking
steps to address the Year 2000 Problem with respect to the computer systems that
they use and to obtain assurances that comparable steps are being taken by the
Fund's other major service providers.  While there can be no assurance that the
Fund's service providers will be Year 2000 compliant, the Fund's service
providers expect that their plans to be compliant will be achieved.


                             MANAGEMENT OF THE FUND

INVESTMENT ADVISER
    
     The Adviser, a wholly-owned indirect subsidiary of PNC Bank, serves as the
Fund's investment adviser.  The Adviser and its affiliates are one of the
largest U.S. bank managers of mutual funds, with assets currently under
management in excess of $46 billion.  BIMC (formerly known as PNC Institutional
Management Corporation or "PIMC") was organized in 1977 by PNC Bank to perform
advisory services for investment companies and has its principal offices at
Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, Delaware
19809.     
    
     As investment adviser, BIMC manages the Fund and is responsible for all
purchases and sales of the Fund's securities.  For the investment advisory
services provided and expenses assumed by it, BIMC is entitled to receive a fee,
computed daily and payable monthly, based on the Fund's average net assets.
BIMC and PFPC, the co-administrator, may from time to time reduce the investment
advisory and administration fees otherwise payable to them or may reimburse the
Fund for its operating expenses.  Any fees waived and any expenses reimbursed by
BIMC and PFPC with respect to a particular fiscal year are not recoverable.  For
the fiscal year ended September 30, 1998, the Fund paid investment advisory fees
and administration fees each aggregating .08% (net of waivers) of its average
net assets. The services provided by BIMC and the fees payable by the Fund for
these     

                                      -11-

services are described further in the Statement of Additional Information under
"Management of the Funds."

                            SHAREHOLDER INFORMATION
                                        
PRICE OF FUND SHARES

     The Fund's net asset value per share for purposes of pricing purchase and
redemption orders is determined by PFPC Inc. ("PFPC"), the Funds co-
administrator, as of 12:00 noon and 4:00 P.M., Eastern time, on each day on
which both the New York Stock Exchange and the Federal Reserve Bank of
Philadelphia are open for business (a "Business Day"). The net asset value per
share of each class of the Fund's shares is calculated by adding the value of
all securities and other assets of the Fund that are allocable to a particular
class, subtracting liabilities charged to such class, and dividing the result by
the total number of outstanding shares of such class.  In computing net asset
value, the Fund uses the amortized cost method of valuation as described in the
Statement of Additional Information under "Additional Purchase and Redemption
Information."  Under the 1940 Act, the Fund may postpone the date of payment of
any redeemable security for up to seven days.

PURCHASE OF SHARES
    
     Fund shares are sold at the net asset value per share next determined after
confirmation of a purchase order by PFPC, which also serves as the Fund's
transfer agent. Purchase orders for shares are accepted only on Business Days
and must be transmitted to PFPC in Wilmington, Delaware by telephone (800-441-
7450; in Delaware: 302-791-5350) or through the Fund's computer access program.
Orders accepted before 12:00 noon, Eastern time, for which payment has been
received by PNC Bank, N.A. ("PNC Bank"), the Fund's custodian, will be executed
at 12:00 noon. Orders accepted after 12:00 noon and before 3:00 P.M., Eastern
time (or orders accepted earlier in the same day for which payment has not been
received by 12:00 noon), will be executed at 4:00 P.M., Eastern time, if payment
has been received by PNC Bank by that time. Orders received at other times, and
orders for which payment has not been received by 4:00 P.M., Eastern time, will
not be accepted, and notice thereof will be given to the institution placing the
order. (Payment for orders which are not received or accepted will be returned
after prompt inquiry to the sending institution.) The Fund may in its discretion
reject any order for shares.     

     Payment for Fund shares may be made only in federal funds or other funds
immediately available to PNC Bank.  The minimum initial investment by an
institution is $3 million for TempCash Shares and $5,000 for TempCash Dollar
Shares; however, broker-dealers and other institutional investors may set a
higher minimum for their customers.  There is no minimum subsequent investment.
The Fund, at its discretion, may reduce the minimum initial investment for
TempCash Shares for specific institutions whose aggregate relationship with the
Provident Institutional Funds is substantially equivalent to this $3 million
minimum and warrants this reduction.

                                      -12-
<PAGE>
 
     Fund shares are sold and redeemed without charge by the Fund.
Institutional investors purchasing or holding Fund shares for their customer
accounts may charge customer fees for cash management and other services
provided in connection with their accounts.  A customer should, therefore,
consider the terms of its account with an institution before purchasing Fund
shares.  An institution purchasing or redeeming Fund shares on behalf of its
customers is responsible for transmitting orders to the Fund in accordance with
its customer agreements.

     Conflict of interest restrictions may apply to an institution's receipt of
compensation paid by the Fund in connection with the investment of fiduciary
funds in TempCash Dollar Shares.  (See also "Management of the Fund -- Service
Organizations," as described in the Statement of Additional Information.)
Institutions, including banks regulated by the Comptroller of the Currency and
investment advisers and other money managers subject to the jurisdiction of the
SEC, the Department of Labor or state securities commissions, are urged to
consult their legal advisors before investing fiduciary funds in TempCash Dollar
Shares.  (See also "Management of the Fund -- Banking Laws," as described in the
Statement of Additional Information.)

REDEMPTION OF SHARES

     Redemption orders must be transmitted to PFPC in Wilmington, Delaware in
the manner described under "Purchase of Shares."  Shares are redeemed at the net
asset value per share next determined after PFPC's receipt of the redemption
order.  While the Fund intends to use its best efforts to maintain its net asset
value per share at $1.00, the proceeds paid to a shareholder upon redemption may
be more or less than the amount invested depending upon a share's net asset
value at the time of redemption.  Call 1-800-441-7450 (in Delaware: 302-791-
5350) to place redemption orders.

     Payment for redeemed shares for which a redemption order is received by
PFPC by 3:00 P.M., Eastern time, on a Business Day is normally made in federal
funds wired to the redeeming shareholder on the same day.  Payment for
redemption orders which are received between 3:00 P.M. and 4:00 P.M., Eastern
time, or on a day when PNC Bank is closed, is normally wired in federal funds on
the next day following redemption that PNC Bank is open for business.

     The Fund shall have the right to redeem shares in any TempCash Shares
account if the value of the account is less than $100,000, and in any TempCash
Dollar Shares account if the value of the account is less than $1,000, after
sixty-days' prior written notice to the shareholder.  Any such redemption shall
be effected at the net asset value next determined after the redemption order is
entered.  If during the sixty-day period the shareholder increases the value of
its TempCash Shares account to $100,000 or more or its TempCash Dollar Shares
account to $1,000 or more, no such redemption shall take place.  In addition,
the Fund may also redeem shares involuntarily under certain special
circumstances described in the Statement of Additional Information under
"Additional Purchase and Redemption Information."

                                      -13-

SHAREHOLDER SERVICE PLAN

     Institutional investors, such as banks, savings and loan associations and
other financial institutions, including affiliates of PNC Bank Corp.  ("Service
Organizations"), may purchase Dollar Shares.  TempCash Dollar Shares are
identical in all respects to TempCash Shares except that they bear the service
fees described below and enjoy certain exclusive voting rights on matters
relating to these fees.  The Fund will enter into an agreement with each Service
Organization which purchases Dollar Shares requiring it to provide support
services to its customers who are the beneficial owners of such shares in
consideration of the Fund's payment of .25% (on an annualized basis) of the
average daily net asset value of the Dollar Shares held by the Service
Organization for the benefit of customers.  Such services, which are described
more fully in the Statement of Additional Information under "Management of the
Fund  Service Organizations," include aggregating and processing purchase and
redemption requests from customers and placing net purchase and redemption
orders with PFPC; processing dividend payments from the Fund on behalf of
customers; providing information periodically to customers showing their
positions in Dollar Shares; and providing sub-accounting or the information
necessary for sub-accounting with respect to Dollar Shares beneficially owned by
customers.  Under the terms of the agreements, Service Organizations are
required to provide to their customers a schedule of any fees that they may
charge customers in connection with their investments in Dollar Shares.
TempCash Shares are sold to institutions that have not entered into servicing
agreements with the Fund in connection with their investments.

DIVIDENDS AND DISTRIBUTIONS

     The Fund declares dividends daily and distributes substantially all of its
net investment income to shareholders monthly.  Shares begin accruing dividends
on the day the purchase order for the shares is effected and continue to accrue
dividends through the day before such shares are redeemed.  Dividends are paid
monthly by check, or by wire transfer if requested in writing by the
shareholder, within five business days after the end of the month or within five
business days after a redemption of all of a shareholder's shares of a
particular class.

     Dividends are determined in the same manner for each class of shares of the
Fund.  TempCash Dollar Shares bear all the expense of fees paid to Service
Organizations, and as a result, at any given time, the dividend on TempCash
Dollar Shares will be approximately .25% lower than the dividend on TempCash
Shares.

     Institutional shareholders may elect to have their dividends reinvested in
additional full and fractional shares of the same class of shares with respect
to which such dividends are declared at the net asset value of such shares on
the payment date.  Reinvested dividends receive the same tax treatment as
dividends paid in cash.  Reinvestment elections, and any revocations thereof,
must be made in writing to PFPC, the Fund's transfer agent, at P.O. Box 8950,
Wilmington, Delaware 19885-9628 and will become effective after its receipt by
PFPC with respect to dividends paid.

TAXES

         
    
     The Fund's distributions will generally be taxable to shareholders. The 
Fund expects that all, or substantially all, of its distributions will consist 
of ordinary income. You will be subject to income tax on these distributions 
regardless whether they are paid in cash or reinvested in additional 
shares.     
    
     PFPC, as transfer agent, will send each Fund shareholder or its authorized 
representative an annual statement designating the amount, if any, of any 
dividends and distributions made during each year and their federal tax 
treatment.     
    
     Dividends declared in December or any year, and payable to shareholders of 
record on a specified date in December, will be deemed to have been received by 
the shareholders and paid by the Fund on December 31 of such year in the event 
such dividends are actually paid during January of the following year.     
    
     You should consult your tax adviser for further information regarding the 
federal, state and local tax consequences with respect to your specific 
situation.

The financial highlights tables are intended to help you understand the Fund's
financial performance for the past 5 years.  Certain information reflects
financial results for a single Fund share.  The total returns in the table
represent the rate that an investor would have earned or lost on an investment
in the Fund (assuming reinvestment of all dividends and distributions).  This
information has been audited by PricewaterhouseCoopers LLP, whose report, along
with the Fund's financial statements, are incorporated by reference into the
Statement of Additional Information and included in the Annual Report, each of
which is available upon request.

                              RISK/RETURN SUMMARY

     
INVESTMENT GOAL:               The Fund seeks current income with liquidity and
                               stability of principal.      
    
INVESTMENT POLICIES:           The Fund invests in a portfolio consisting of
                               U.S. Treasury bills, notes and other obligations
                               issued or guaranteed by the U.S. Government, its
                               agencies or instrumentalities and repurchase
                               agreements relating to such obligations.      
    
PRINCIPAL RISKS OF INVESTING:  Securities issued or guaranteed by the U.S.
                               Government, its agencies and instrumentalities
                               have historically involved little risk of loss of
                               principal if held to maturity. However, due to
                               fluctuations in interest rates, the market value
                               of such securities may vary during the period a
                               shareholder owns shares of the Fund. While the
                               Fund seeks to maintain a constant net asset value
                               of $1.00 per share, the Fund is subject to risks
                               related to changes in prevailing interest rates,
                               since generally, a fixed-income security will
                               increase in value when interest rates fall and
                               decrease in value when interest rates rise. 

                               An investment in the Fund is not a deposit in PNC
                               Bank, N.A. and is not insured or guaranteed by
                               the Federal Deposit Insurance Corporation or any
                               other government agency. Although the Fund seeks
                               to preserve the value of your investment at $1.00
                               per share, it is possible to lose money by
                               investing in the Fund.

                              of principal. The Fund is particularly suitable
                              for banks, corporations and other financial

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods.  The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same.  Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                   INVESTMENT STRATEGIES AND RISK DISCLOSURE

     The Fund is a money market fund.  The investment objective of the Fund is
to seek current income with liquidity and security of principal.  The Fund's
investment objective may be changed by the Board of Trustees without shareholder
approval.  The Fund invests in obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities (in addition to direct Treasury
obligations) and repurchase agreements relating to such obligations.
    
     The Fund invests in securities maturing within 13 months or less from the
date of purchase, with certain exceptions. For example, certain government
securities held by the Fund may have remaining maturities exceeding 13 months if
such securities provide for adjustments in their interest rates not less
frequently than every 13 months. The securities purchased by the Fund are also
subject to the quality, diversification, and other requirements of Rule 2a-7
under the Investment Company Act of 1940, as amended, and other rules of the
Securities and Exchange Commission.      
    
     INVESTMENTS.  The Fund's investments may include the following:      

     U.S. Government Obligations.  The Fund may purchase obligations issued or
guaranteed by the U.S. Government or its agencies and instrumentalities and
related custodial receipts.
    
     Investment Company Securities.  The Fund may invest in securities issued by
other open-end investment companies that invest in the type of obligations in
which the Fund may invest and that determine their net asset value per share
based upon the amortized cost or penny rounding method. Investments in the
securities of other investment companies will cause the Fund (and, indirectly
the Fund's shareholders) to bear proportionately the costs incurred in
connection with the other investment companies' operations.     

     Repurchase Agreements.   The Fund may enter into repurchase agreements.
    
     Reverse Repurchase Agreements and Securities Lending.  The Fund may enter
into reverse  repurchase agreements.  The Fund is permitted to invest up to one-
third of its total assets in reverse repurchase agreements.  The Fund may also
lend its securities with a value of up to one-third of its total assets
(including the value of the collateral for the loan) to qualified brokers,
dealers, banks and other financial institutions for the purpose of realizing
additional net investment income through the receipt of interest on the loan.
Investments in reverse repurchase agreements and securities lending transactions
will be aggregated for purposes of this investment limitation.      

     When-Issued and Delayed Settlement Transactions.  The Fund may purchase
securities on a "when-issued" or "delayed settlement" basis.  The Fund expects
that commitments to purchase when-issued or delayed settlement securities will
not exceed 25% of the value of its total assets absent unusual market
conditions.  The Fund does not intend to purchase when-issued or delayed
settlement securities for speculative purposes but only in furtherance of its
investment objective.

     Other Types of Investments.  This Prospectus describes the Fund's
principal investment strategies, and the particular types of securities in which
the Fund principally invests.  The Fund may, from time to time, make other types
of investments and pursue other investment strategies in support of its overall
investment goal.  These supplemental investment strategies are described in
detail in the Statement of Additional Information, which is referred to on the
back cover of this Prospectus.

     RISK FACTORS.  The principal risks of investing in the Fund are also
described above in the Risk/Return Summary. The following supplements that
description.

     Interest Rate Risk.  Generally, a fixed-income security will increase in
value when interest rates fall and decrease in value when interest rates rise.
As a result, if interest rates were to change rapidly, there is a risk that the
change in market value of the Fund's assets may not enable the Fund to maintain
a stable net asset value of $1.00 per share.

     Credit Risk.  The risk that an issuer will be unable to make principal and
interest payments when due is known as "credit risk."  U.S. Government
securities are generally considered to be the safest type of investment in terms
of credit risk.  Not all U.S. Government Securities are backed by the full faith
and credit of the United States.  Obligations of certain agencies and
instrumentalities of the U.S. Government are backed by the full faith and credit
of the United States.  Others are backed by the right of the issuer to borrow
from the U.S. Treasury or are backed only by the credit of the agency or
instrumentality issuing the obligation.
    
     Other Risks.  Certain investment strategies employed  by the Fund may
involve additional investment risk. Reverse repurchase agreements, securities
lending transactions and when-issued or delayed settlement transactions may
involve leverage risk. Leverage risk is associated with securities or practices
that multiply small market movements into larger changes in the value of the
Fund's investment portfolio. The Fund does not currently intend to employ 
investment strategies that involve leverage risk.      

     Year 2000.  Like other mutual funds, financial and business organizations
and individuals around the world, the Fund could be adversely affected if the
computer systems used by the Adviser and the Fund's other service providers, or
persons with whom they deal, do not properly process and calculate date-related
information and data from and after January 1, 2000.  This possibility is
commonly known as the "Year 2000 Problem."  The Fund has been advised by the
Adviser, the Administrators and the Custodian that they are actively taking
steps to address the Year 2000 Problem with respect to the computer systems that
they use and to obtain assurances that comparable steps are being taken by the
Fund's other major service providers.  While there can be no assurance that the
Fund's service providers will be Year 2000 compliant, the Fund's service
providers expect that their plans to be compliant will be achieved.

                            MANAGEMENT OF THE FUND

INVESTMENT ADVISER
    
     The Adviser, a wholly-owned indirect subsidiary of PNC Bank, serves as the
Fund's investment adviser.  The Adviser and its affiliates are one of the
largest U.S. bank managers of mutual funds, with assets currently under
management in excess of $46 billion.  BIMC (formerly known as PNC Institutional
Management Corporation or "PIMC") was organized in 1977 by PNC Bank to perform
advisory services for investment companies and has its principal offices at
Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, Delaware
19809.      
    
     As investment adviser, BIMC manages the Fund and is responsible for all
purchases and sales of the Fund's securities.  For the investment advisory
services provided and expenses assumed by it, BIMC is entitled to receive a fee,
computed daily and payable monthly, based on the Fund's average net assets.
BIMC and PFPC, the co-administrator, may from time to time reduce the investment
advisory and administration fees otherwise payable to them or may reimburse the
Fund for its operating expenses.  Any fees waived and any expenses reimbursed by
BIMC and PFPC with respect to a particular fiscal year are not recoverable.  For
the fiscal year ended October 31, 1998, the Fund paid investment advisory fees
and administration fees each aggregating .08% (net of waivers) of its average
net assets. The services provided by BIMC and the fees payable by the Fund for
these services are described further in the Statement of Additional Information
under "Management of the Funds."      

                            SHAREHOLDER INFORMATION

PRICE OF FUND SHARES

     The Fund's net asset value per share for purposes of pricing purchase and
redemption orders is determined by PFPC Inc. ("PFPC"), the Funds co-
administrator, as of 12:00 noon and 4:00 P.M., Eastern time, on each day on
which both the New York Stock Exchange and the Federal Reserve Bank of
Philadelphia are open for business (a "Business Day"). The net asset value per
share of each class of the Fund's shares is calculated by adding the value of
all securities and other assets of the Fund that are allocable to a particular
class, subtracting liabilities charged to such class, and dividing the result by
the total number of outstanding shares of such class.  In computing net asset
value, the Fund uses the amortized cost method of valuation as described in the
Statement of Additional Information under "Additional Purchase and Redemption
Information."  Under the 1940 Act, the Fund may postpone the date of payment of
any redeemable security for up to seven days.

                                      -10-
<PAGE>
 
PURCHASE OF SHARES
    
     Fund shares are sold at the net asset value per share next determined after
confirmation of a purchase order by PFPC, which also serves as the Fund's
transfer agent. Purchase orders for shares are accepted only on Business Days
and must be transmitted to PFPC in Wilmington, Delaware by telephone (800-441-
7450; in Delaware: 302-791-5350) or through the Fund's computer access program.
Orders accepted before 12:00 noon, Eastern time, for which payment has been
received by PNC Bank, N.A. ("PNC Bank"), the Fund's custodian, will be executed
at 12:00 noon. Orders accepted after 12:00 noon and before 3:00 P.M., Eastern
time (or orders accepted earlier in the same day for which payment has not been
received by 12:00 noon), will be executed at 4:00 P.M., Eastern time, if payment
has been received by PNC Bank by that time. Orders received at other times, and
orders for which payment has not been received by 4:00 P.M., Eastern time, will
not be accepted, and notice thereof will be given to the institution placing the
order. (Payment for orders which are not received or accepted will be returned
after prompt inquiry to the sending institution.) The Fund may in its discretion
reject any order for shares.      

                                      -11-
<PAGE>
 
     Payment for Fund shares may be made only in federal funds or other funds
immediately available to PNC Bank.  The minimum initial investment by an
institution is $3 million for FedFund Shares and $5,000 for FedFund Dollar
Shares; however, broker-dealers and other institutional investors may set a
higher minimum for their customers.  There is no minimum subsequent investment.
The Fund, at its discretion, may reduce the minimum initial investment for
FedFund Shares for specific institutions whose aggregate relationship with the
Provident Institutional Funds is substantially equivalent to this $3 million
minimum and warrants this reduction.

     Fund shares are sold and redeemed without charge by the Fund.
Institutional investors purchasing or holding Fund shares for their customer
accounts may charge customer fees for cash management and other services
provided in connection with their accounts.  A customer should, therefore,
consider the terms of its account with an institution before purchasing Fund
shares.  An institution purchasing or redeeming Fund shares on behalf of its
customers is responsible for transmitting orders to the Fund in accordance with
its customer agreements.

     Conflict of interest restrictions may apply to an institution's receipt of
compensation paid by the Fund in connection with the investment of fiduciary
funds in FedFund Dollar Shares.  (See also "Management of the Fund -- Service
Organizations," as described in the Statement of Additional Information.)
Institutions, including banks regulated by the Comptroller of the Currency and
investment advisers and other money managers subject to the jurisdiction of the
SEC, the Department of Labor or state securities commissions, are urged to
consult their legal advisors before investing fiduciary funds in FedFund Dollar
Shares.  (See also "Management of the Fund -- Banking Laws," as described in the
Statement of Additional Information.)


REDEMPTION OF SHARES

     Redemption orders must be transmitted to PFPC in Wilmington, Delaware in
the manner described under "Purchase of Shares."  Shares are redeemed at the net
asset value per share next determined after PFPC's receipt of the redemption
order.  While the Fund intends to use its best efforts to maintain its net asset
value per share at $1.00, the proceeds paid to a shareholder upon redemption may
be more or less than the amount invested depending upon a share's net asset
value at the time of redemption.  Call 1-800-441-7450 (in Delaware: 302-791-
5350) to place redemption orders.

     Payment for redeemed shares for which a redemption order is received by
PFPC by 3:00 P.M., Eastern time, on a Business Day is normally made in federal
funds wired to the redeeming shareholder on the same day.  Payment for
redemption orders which are received between 3:00 P.M. and 4:00 P.M., Eastern
time, or on a day when PNC Bank is closed is normally wired in federal funds on
the next day following redemption that PNC Bank is open for business.

                                      -12-
<PAGE>
 
     The Fund shall have the right to redeem shares in any account if the value
of the account is less than $1,000, after sixty-days' prior written notice to
the shareholder.  Any such redemption shall be effected at the net asset value
next determined after the redemption order is entered.  If during the sixty-day
period the shareholder increases the value of its account to $1,000 or more, no
such redemption shall take place.  Moreover, if a shareholder's FedFund Shares
account falls below an average of $100,000 in any particular calendar month, the
account may be charged an account maintenance fee with respect to that month.
In addition, the Fund may also redeem shares involuntarily under certain special
circumstances described in the Statement of Additional Information under
"Additional Purchase and Redemption Information."


SHAREHOLDER SERVICE PLAN

     Institutional investors, such as banks, savings and loan associations and
other financial institutions, including affiliates of PNC Bank Corp.  ("Service
Organizations"), may purchase Dollar Shares.  FedFund Dollar Shares are
identical in all respects to FedFund Shares except that they bear the service
fees described below and enjoy certain exclusive voting rights on matters
relating to these fees.  The Fund will enter into an agreement with each Service
Organization which purchases Dollar Shares requiring it to provide support
services to its customers who are the beneficial owners of such shares in
consideration of the Fund's payment of .25% (on an annualized basis) of the
average daily net asset value of the Dollar Shares held by the Service
Organization for the benefit of customers.  Such services, which are described
more fully in the Statement of Additional Information under "Management of the
Fund - Service Organizations," include aggregating and processing purchase and
redemption requests from customers and placing net purchase and redemption
orders with PFPC; processing dividend payments from the Fund on behalf of
customers; providing information periodically to customers showing their
positions in Dollar Shares; and providing sub-accounting or the information
necessary for sub-accounting with respect to Dollar Shares beneficially owned by
customers.  Under the terms of the agreements, Service Organizations are
required to provide to their customers a schedule of any fees that they may
charge customers in connection with their investments in Dollar Shares.  FedFund
Shares are sold to institutions that have not entered into servicing agreements
with the Fund in connection with their investments.

DIVIDENDS AND DISTRIBUTIONS 


     The Fund declares dividends daily and distributes substantially all of its
net investment income to shareholders monthly.  Shares begin accruing dividends
on the day the purchase order for the shares is effected and continue to accrue
dividends through the day before such shares are redeemed.  Dividends are paid
monthly by check, or by wire transfer if requested in writing by the
shareholder, within five business days after the end of the month or within five
business days after a redemption of all of a shareholder's shares of a
particular class.

     Dividends are determined in the same manner for each class of shares of the
Fund.  FedFund Dollar Shares bear all the expense of fees paid to Service
Organizations, and as a result, at any given time, the dividend on FedFund
Dollar Shares will be approximately .25% lower than the dividend on FedFund
Shares.

                                      -13-
<PAGE>
 
     Institutional shareholders may elect to have their dividends reinvested in
additional full and fractional shares of the same class of shares with respect
to which such dividends are declared at the net asset value of such shares on
the payment date.  Reinvested dividends receive the same tax treatment as
dividends paid in cash.  Reinvestment elections, and any revocations thereof,
must be made in writing to PFPC, the Fund's transfer agent, at P.O. Box 8950,
Wilmington, Delaware 19885-9628 and will become effective after its receipt by
PFPC with respect to dividends paid.

TAXES
    
     The Fund's distributions will generally be taxable to shareholders. The
Fund expects that all, or substantially all, of its distributions will consist
of ordinary income. You will be subject to income tax on these distributions
regardless whether they are paid in cash or reinvested in additional shares.
     
    
     PFPC, as transfer agent, will send each Fund shareholder or its authorized 
representative an annual statement designating the amount, if any, of any 
dividends and distributions made during each year and their federal tax 
treatment.     
    
     Dividends declared in December of any year, and payable to shareholders of 
record on a specified date in December, will be deemed to have been received by 
the shareholders and paid by the Fund on December 31 of such year in the event 
such dividends are actually paid during January of the following year.     
    
     You should consult your tax adviser for further information regarding the 
federal, state and local tax consequences with respect to your specific 
situation.

The financial highlights tables are intended to help you understand the Fund's
financial performance for the past 5 years.  Certain information reflects
financial results for a single Fund share.  The total returns in the table
represent the rate that an investor would have earned or lost on an investment
in the Fund (assuming reinvestment of all dividends and distributions).  This
information has been audited by PricewaterhouseCoopers LLP, whose report, along
with the Fund's financial statements, are incorporated by reference into the
Statement of Additional Information and included in the Annual Report, each of
which is available upon request.

                              RISK/RETURN SUMMARY

     
INVESTMENT GOAL:                   The Fund seeks current income with liquidity
                                   and stability of principal.      
    
INVESTMENT POLICIES:               The Fund invests in U.S. Treasury bills, 
                                   notes, trust receipts and direct obligations
                                   of the U.S. Treasury and repurchase
                                   agreements relating to direct Treasury
                                   obligations.      

PRINCIPAL RISK OF INVESTING:       Securities issued or guaranteed by the U.S.
                                   Government have historically involved little
                                   risk of loss of principal if held to
                                   maturity. However, due to fluctuations in
                                   interest rates, the market value of such
                                   securities may vary during the period a
                                   shareholder owns shares of the Fund. While
                                   the Fund seeks to maintain a constant net
                                   asset value of $1.00 per share, the Fund is
                                   subject to risks related to changes in
                                   prevailing interest rates, since generally, a
                                   fixed-income security will increase in value
                                   when interest rates fall and decrease in
                                   value when interest rates rise.

                                   An investment in the Fund is not a deposit in
                                   PNC Bank, N.A. and is not insured or
                                   guaranteed by the Federal Deposit Insurance
                                   Corporation or any other government agency.
                                   Although the Fund seeks to preserve the value
                                   of your investment at $1.00 per share, it is
                                   possible to lose money by investing in the
                                   Fund.

the "Adviser") and PFPC Inc., the Fund's co-administrator, may from time to time
waive the investment advisory and administration fees otherwise payable to them
or may reimburse the Fund for its operating expenses. The Adviser and PFPC

prior written notice to the Fund.

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods.  The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same.  Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                   INVESTMENT STRATEGIES AND RISK DISCLOSURE
    
     The Fund is a money market fund. The investment objective of the Fund is to
seek current income with liquidity and security of principal. The Fund's
investment objective may be changed by the Board of Trustees without shareholder
approval. The Fund invests solely in direct obligations of the U.S. Treasury,
such as Treasury bills, notes, trust receipts and repurchase agreements relating
to direct Treasury obligations.      
    
     The Fund invests in securities maturing within 13 months or less from
the date of purchase, with certain exceptions.  For example, certain government
securities held by the Fund may have remaining maturities exceeding 13 months if
such securities provide for adjustments in their interest rates not less
frequently than every 13 months.  The securities purchased by the Fund are also
subject to the quality, diversification, and other requirements of Rule 2a-7
under the Investment Company Act of 1940, as amended, and other rules of the
Securities and Exchange Commission.      
    
     INVESTMENTS.  The Fund's investments may include the following:      
    
     U.S. Treasury Obligations.  The Fund may purchase direct obligations of the
U.S. Treasury. The Fund may invest in Treasury receipts where the principal and 
interest components are traded separately under the Separate Trading of 
Registered Interest and Principal of Securities program ("STRIPS").      
         
    
     Investment Company Securities.  The Fund may invest in securities issued by
other open-end investment companies that invest in the type of obligations in
which the Fund may invest and that determine their net asset value per share
based upon the amortized cost or penny rounding method. Investments in the 
securities of other investment companies will cause the Fund (and, indirectly 
the Fund's shareholders) to bear proportionately the costs incurred in 
connection with the other investment companies' operations.      

     Repurchase Agreements.   The Fund may enter into repurchase agreements.
    
     Reverse Repurchase Agreements and Securities Lending.  The Fund may enter
into reverse  repurchase agreements.  The Fund is permitted to invest up to one-
third of its total assets in reverse repurchase agreements.  The Fund may also
lend its securities with a value of up to one-third of its total assets
(including the value of the collateral for the loan) to qualified brokers,
dealers, banks and other financial institutions for the purpose of realizing
additional net investment income through the receipt of interest on the loan.
Investments in reverse repurchase agreements and securities lending transactions
will be aggregated for purposes of this investment limitation.      

     When-Issued and Delayed Settlement Transactions.  The Fund may purchase
securities on a "when-issued" or "delayed settlement" basis.  The Fund expects
that commitments to purchase when-issued or delayed settlement securities will
not exceed 25% of the value of its total assets absent unusual market
conditions.  The Fund does not intend to purchase when-issued or delayed
settlement securities for speculative purposes but only in furtherance of its
investment objective.

     Other Types of Investments.  This Prospectus describes the Fund's
principal investment strategies, and the particular types of securities in which
the Fund principally invests.  The Fund may, from time to time, make other types
of investments and pursue other investment strategies 

                                      -8-

in support of its overall investment goal. These supplemental investment
strategies are described in detail in the Statement of Additional Information,
which is referred to on the back cover of this Prospectus.

     RISK FACTORS.  The principal risks of investing in the Fund are also
described above in the Risk/Return Summary.  The following supplements that
description.

     Interest Rate Risk.  Generally, a fixed-income security will increase in
value when interest rates fall and decrease in value when interest rates rise.
As a result, if interest rates were to change rapidly, there is a risk that the
change in market value of the Fund's assets may not enable the Fund to maintain
a stable net asset value of $1.00 per share.
    
     Credit Risk.  The risk that an issuer will be unable to make principal and
interest payments when due is known as "credit risk." U.S. Treasury securities
are considered to be the safest type of investment in terms of credit risk. 
     
    
     Other Risks. Certain investment strategies employed by the Fund may involve
additional investment risk. Reverse repurchase agreements, securities lending
transactions and when-issued or delayed settlement transactions may involve
leverage risk. Leverage risk is associated with securities or practices that
multiply small market movements into larger changes in the value of the Fund's
investment portfolio. The Fund does not currently intend to employ investment
strategies that involve leverage risk.     

     Year 2000.  Like other mutual funds, financial and business organizations
and individuals around the world, the Fund could be adversely affected if the
computer systems used by the Adviser and the Fund's other service providers, or
persons with whom they deal, do not properly process and calculate date-related
information and data from and after January 1, 2000.  This possibility is
commonly known as the "Year 2000 Problem."  The Fund has been advised by the
Adviser, the Administrators and the Custodian that they are actively taking
steps to address the Year 2000 Problem with respect to the computer systems that
they use and to obtain assurances that comparable steps are being taken by the
Fund's other major service providers.  While there can be no assurance that the
Fund's service providers will be Year 2000 compliant, the Fund's service
providers expect that their plans to be compliant will be achieved.

                            MANAGEMENT OF THE FUND

INVESTMENT ADVISER
    
     The Adviser, a wholly-owned indirect subsidiary of PNC Bank, serves as the
Fund's investment adviser.  The Adviser and its affiliates are one of the
largest U.S. bank managers of mutual funds, with assets currently under
management in excess of $46 billion.  BIMC (formerly known as PNC Institutional
Management Corporation or "PIMC") was organized in 1977 by PNC Bank to perform
advisory services for investment companies and has its principal offices at
Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, Delaware
19809.      

                                      -9-
<PAGE>
     
     As investment adviser, BIMC manages the Fund and is responsible for all
purchases and sales of the Fund's securities. For the investment advisory
services provided and expenses assumed by it, BIMC is entitled to receive a fee,
computed daily and payable monthly, based on the Fund's average net assets. BIMC
and PFPC, the co-administrator, may from time to time reduce the investment
advisory and administration fees otherwise payable to them or may reimburse the
Fund for its operating expenses. Any fees waived and any expenses reimbursed by
BIMC and PFPC with respect to a particular fiscal year are not recoverable. For
the fiscal year ended October 31, 1998, the Fund paid investment advisory fees
and administration fees each aggregating .09% (net of waivers) of its average
net assets. The services provided by BIMC and the fees payable by the Fund for
these services are described further in the Statement of Additional Information
under "Management of the Funds."      

                            SHAREHOLDER INFORMATION

PRICE OF FUND SHARES
    
     The Fund's net asset value per share for purposes of pricing purchase and
redemption orders is determined by PFPC Inc. ("PFPC"), the Funds co-
administrator, as of 12:00 noon and 5:30 P.M., Eastern time, on each day on
which both the New York Stock Exchange and the Federal Reserve Bank of
Philadelphia are open for business (a "Business Day"). The net asset value per
share of each class of the Fund's shares is calculated by adding the value of
all securities and other assets of the Fund that are allocable to a particular
class, subtracting liabilities charged to such class, and dividing the result by
the total number of outstanding shares of such class. In computing net asset
value, the Fund uses the amortized cost method of valuation as described in the
Statement of Additional Information under "Additional Purchase and Redemption
Information." Under the 1940 Act, the Fund may postpone the date of payment of
any redeemable security for up to seven days.     

PURCHASE OF SHARES

     Fund shares are sold at the net asset value per share next determined after
confirmation of a purchase order by PFPC, which also serves as the Fund's
transfer agent. Purchase orders for shares are accepted only on Business Days
and must be transmitted to PFPC in Wilmington, Delaware by telephone (800-441-
7450; in Delaware: 302-791-5350) or through the Fund's computer access program.
Orders accepted before 12:00 noon, Eastern time, for which payment has been
received by PNC Bank, N.A. ("PNC Bank"), the Fund's custodian, will be executed
at 12:00 noon. Orders accepted after 12:00 noon and before 5:30 P.M., Eastern
time (or orders accepted earlier in the same day for which payment has not been
received by 12:00 noon), will be executed at 5:30 P.M., Eastern time, if payment
has been received by PNC Bank by that time. Orders received at other times, and
orders for which payment has not been received by 5:30 P.M., Eastern time, will
not be accepted, and notice thereof will be given to the institution placing the
order. (Payment for orders which are not received or accepted will be returned
after prompt inquiry to the sending institution.) Between 3:00 P.M. and 5:30
P.M., Eastern time, purchase orders may only be transmitted by telephone, and
the Fund reserves the right to limit the amount of such orders. The Fund may in
its discretion reject any order for shares.

                                      -10-
<PAGE>
 
     Payment for Fund shares may be made only in federal funds or other funds
immediately available to PNC Bank. The minimum initial investment by an
institution is $3 million for T-Fund Shares; there is no minimum initial
investment for T-Fund Administration Shares, T-Fund Dollar Shares, T-Fund Plus
Shares, T-Fund Cash Reserve Shares or T-Fund Cash Management Shares, however,
broker-dealers and other institutional investors may set a minimum for their
customers. There is no minimum subsequent investment. The Fund, at its
discretion, may reduce the minimum initial investment for T-Fund Shares for
specific institutions whose aggregate relationship with the Provident
Institutional Funds is substantially equivalent to this $3 million minimum and
warrants this reduction.

     Fund shares are sold and redeemed without charge by the Fund.
Institutional investors purchasing or holding Fund shares for their customer
accounts may charge customer fees for cash management and other services
provided in connection with their accounts.  A customer should, therefore,
consider the terms of its account with an institution before purchasing Fund
shares.  An institution purchasing or redeeming Fund shares on behalf of its
customers is responsible for transmitting orders to the Fund in accordance with
its customer agreements.

     Conflict of interest restrictions may apply to an institution's receipt of
compensation paid by the Fund in connection with the investment of fiduciary
funds in T-Fund Administration Shares, T-Fund Dollar Shares, T-Fund Plus Shares,
T-Fund Cash Reserve Shares and T-Fund Cash Management Shares. (See also
"Management of the Fund - Organizations," as described in the Statement of
Additional Information.) Institutions, including banks regulated by the
Comptroller of the Currency and investment advisers and other money managers
subject to the jurisdiction of the SEC, the Department of Labor or state
securities commissions, are urged to consult their legal advisors before
investing fiduciary funds in T-Fund Administration Shares, T-Fund Dollar Shares,
T-Fund Plus Shares, T-Fund Cash Reserve Shares and T-Fund Cash Management
Shares. (See also "Management of the Fund -- Banking Laws," as described in the
Statement of Additional Information.)

REDEMPTION OF SHARES

     Redemption orders must be transmitted to PFPC in Wilmington, Delaware in
the manner described under "Purchase of Shares."  Shares are redeemed at the net
asset value per share next determined after PFPC's receipt of the redemption
order.  Telephone instructions for redemptions received between 3:00 P.M. and
5:30 P.M., Eastern time, on a Business Day are received for execution on that
same day, however, the Fund reserves the right to make payment for such
redemptions the next Business Day.  While the Fund intends to use its best
efforts to maintain its net asset value per share at $1.00, the proceeds paid to
a shareholder upon redemption may be more or less than the amount invested
depending upon a share's net asset value at the time of redemption.  Call 1-800-
441-7450 (in Delaware: 302-791-5350) to place redemption orders.

     Payment for redeemed shares for which a redemption order is received by
PFPC by 5:30 P.M., Eastern time, on a Business Day is normally made in federal
funds wired to the redeeming shareholder on the same day.  Payment for
redemption orders which are received on a day when PNC Bank is closed is
normally wired in federal funds on the next day following redemption that PNC
Bank is open for business.

     The Fund shall have the right to redeem shares in any account if the value
of the account is less than $1,000 after sixty-days' prior written notice to
the shareholder.  Any such redemption shall be effected at the net asset value
next determined after the redemption order is entered.  If during the sixty-day
period the shareholder increases the value of its account to $1,000 or more, no
such redemption shall take place.  Moreover, if a shareholder's T-Fund Shares
account falls 

                                      -11-
<PAGE>
 
below an average of $100,000 in any particular calendar month, the account may
be charged an account maintenance fee with respect to that month. In addition,
the Fund may also redeem shares involuntarily under certain special
circumstances described in the Statement of Additional Information under
"Additional Purchase and Redemption Information."

DISTRIBUTION AND SHAREHOLDER SERVICE PLANS

     The Fund offers six classes of shares. The difference between the classes 
of shares is the fees borne by a class of shares pursuant to separate fee plans 
adopted by each class. T-Fund Shares do not bear any fees for distribution, 
servicing, shareholder servicing, sweep fees or cash sweep marketing services. 
The fees borne by the other classes are as follows:

- --------------------------------------------------------------------------------
                                                              CASH

     Service Fees are paid for general shareholder liaison services. Shareholder
Service Fees are paid for services relating to the processing and administration
of shareholder accounts. The Fund has adopted a plan pursuant to Rule 12b-1. 
12b-1 Fees are paid for distribution and sales support, and shareholder
services. Cash Sweep Fees are paid for providing a sweep service into the Fund.
Cash Sweep Marketing Fees are paid for providing marketing administrative
activities in connection with the sweep program.     

     Shares of the Fund are not sold to individuals, but may be sold to the
following entities, which hold the shares for the accounts of their customers.
Administration Shares, Dollar Shares, Cash Reserve Shares and Cash Management 
Shares are sold to institutional investors such as banks, saving and loan
associations, and other financial institutions, including affiliates of PNC Bank
Corp. ("Service Organizations"). Plus Shares are sold to broker-dealers. Because
fees associated with the distribution and/or shareholder service plans are paid
out of the Fund's assets on an ongoing basis, over time holders of the share
classes described above may pay more than the economic equivalent of the maximum
front-end sales charge permitted by NASD regulation, Inc.

DIVIDENDS AND DISTRIBUTIONS 

     The Fund declares daily and distributes substantially all of its net
investment income to shareholders monthly. Shares begin accruing dividends on
the day the purchase order for the shares is effected and continue to accrue
dividends through the day before such shares are redeemed. Dividends are paid
monthly by check, or by wire transfer if requested in writing by the
shareholder, within five business days after the end of the month or within five
business days after a redemption of all of a shareholder's shares of a
particular class.

     Institutional shareholders may elect to have their dividends reinvested in
additional full and fractional shares of the same class of shares with respect
to which such dividends are declared at the net asset value of such shares on
the payment date.  Reinvested dividends receive the same tax treatment as
dividends paid in cash.  Reinvestment elections, and any revocations thereof,
must be made in writing to PFPC, the Fund's transfer agent, at P.O. Box 8950,
Wilmington, Delaware 19885-9628 and will become effective after its receipt by
PFPC with respect to dividends paid.

<PAGE>
 
TAXES
         
    
     The Fund's distributions will generally be taxable to shareholders. The 
Fund expects that all, or substantially all, of its distributions will consist 
of ordinary income. You will be subject to income tax on these distributions 
regardless whether they are paid in cash or reinvested in additional shares. 
     
    
     Shareholders will generally not be subject to state and local taxes on 
distributions to the extent attributable to interest on U.S. Treasury 
obligations. State income taxes may apply however to the portion of the Fund's 
distributions, if any, that are attributable to interest on obligations that are
not Federal Securities, such as repurchase agreements.      
    
     PFPC, as transfer agent, will send each Fund shareholder or its authorized 
representative an annual statement designating the amount, if any, of any 
dividends and distributions made during each year and their federal tax 
treatment.      
    
     Dividends declared in December of any year, and payable to shareholders of 
record on a specified date in December, will be deemed to have been received by 
the shareholders and paid by the Fund on December 31 of such year in the event 
such dividends are actually paid during January of the following year.      
    
     You should consult your tax adviser for further information regarding the 
federal, state and local tax consequences with respect to your specific 
situation.

                             FINANCIAL HIGHLIGHTS
    
The financial highlights tables are intended to help you understand the Fund's
financial performance for the past 5 years. Certain information reflects
financial results for a single Fund share. The total returns in the table
represent the rate that an investor would have earned or lost on an investment
in the Fund (assuming reinvestment of all dividends and distributions). This
information has been audited by PricewaterhouseCoopers LLP, whose report, along
with the Fund's financial statements, are incorporated by reference into the
Statement of Additional Information and included in the Annual Report, each of
which is available upon request. Administration Shares, Plus Shares, Cash
Reserve Shares and Cash Management Shares of the Fund have not yet commenced
operations, therefore no financial information has been provided for these
classes.

                              RISK/RETURN SUMMARY


     
INVESTMENT GOAL:                   The Fund seeks current income with liquidity
                                   and stability of principal.      
     
INVESTMENT POLICIES:               The Fund invests solely in direct 
                                   obligations of the U.S. Treasury, such as
                                   Treasury bills, notes and trust receipts.
                                   Because the Fund invests exclusively in
                                   direct U.S. Treasury obligations, investors
                                   may benefit from income tax exclusions or
                                   exemptions that are available in certain
                                   states and localities.      

    
PRINCIPAL RISKS OF INVESTING:      Securities issued or guaranteed by the U.S.
                                   Government have historically involved little
                                   risk of loss of principal if held to
                                   maturity. However, due to fluctuations in
                                   interest rates, the market value of such
                                   securities may vary during the period a
                                   shareholder owns shares of the Fund. While 
                                   the Fund seeks to maintain a constant net 
                                   asset value of $1.00 per share, the Fund is 
                                   subject to risks related to changes in 
                                   prevailing interest rates, since generally, a
                                   fixed-income security will increase in value
                                   when interest rates fall and decrease in
                                   value when interest rates rise.      

                                   The Fund may from time to time engage in
                                   portfolio trading for liquidity purposes, in
                                   order to enhance its yield or if otherwise
                                   deemed advisable. In selling securities prior
                                   to maturity, the Fund may realize a price
                                   higher or lower than that paid to acquire any
                                   given security, depending upon whether
                                   interest rates have decreased or increased
                                   since its acquisition. In addition,
                                   shareholders in a particular state that
                                   imposes income tax should determine through
                                   consultation with their own tax advisors
                                   whether such interest income, when
                                   distributed by the Fund, will be considered
                                   by the state to have retained exempt status,
                                   and whether the Fund's capital gain and other
                                   income, if any, when distributed will be
                                   subject to the states income tax.

                                   Although the Fund seeks to preserve the value
                                   of your investment at $1.00 per share, it is
                                   possible to lose money by investing in the
                                   Fund.

waive the investment advisory and administration fees otherwise payable to them
or may reimburse the Fund for its operating expenses. The Adviser and PFPC
expect to continue such fee waivers, but can terminate the waivers upon 120 days

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods.  The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same.  Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                   INVESTMENT STRATEGIES AND RISK DISCLOSURE
                                            
     The Fund is a money market fund.  The investment objective of the Fund is
to seek current income with liquidity and security of principal.  The Fund's
investment objective may be changed by the Board of Trustees without shareholder
approval.  The Fund invests solely in direct obligations of the U.S. Treasury,
such as Treasury bills, notes and trust receipts.      
    
     The Fund invests in securities maturing within one year or less, with
certain exceptions. For example, certain government securities held by the Fund
may have remaining maturities exceeding 13 months if such securities provide for
adjustments in their interest rates not less frequently than every 13 months.
The securities purchased by the Fund are also subject to the quality,
diversification, and other requirements of Rule 2a-7 under the Investment
Company Act of 1940, as amended, and other rules of the Securities and Exchange
Commission.      
    
     INVESTMENTS.  The Fund's investments may include the following:      

         
    
     U.S. Treasury Obligations. To the extent consistent with its investment
objectives, the Fund may invest in direct obligations of the U.S. Treasury. The
Fund may invest in Treasury receipts where the principal and interest components
are traded separately under the Separate Trading of Registered Interest and
Principal of Securities program ("STRIPS").     
    
     Investment Company Securities.  The Fund may invest in securities issued by
other open-end investment companies that invest in the type of obligations in
which the Fund may invest and that determine their net asset value per share
based upon the amortized cost or penny rounding method. Investments in the 
securities of other investment companies will cause the Fund (and, indirectly 
the Fund's shareholders) to bear proportionately the costs incurred in 
connection with the other investment companies' operations.      

     When-Issued and Delayed Settlement Transactions.  The Fund may purchase
securities on a "when-issued" or "delayed settlement" basis.  The Fund expects
that commitments to purchase when-issued or delayed settlement securities will
not exceed 25% of the value of its total assets absent unusual market
conditions.  The Fund does not intend to purchase when-issued or delayed
settlement securities for speculative purposes but only in furtherance of its
investment objective.

     Other Types of Investments.  This Prospectus describes the Fund's
principal investment strategies, and the particular types of securities in which
the Fund principally invests.  The Fund may, from time to time, make other types
of investments and pursue other investment strategies in support of its overall
investment goal.  These supplemental investment strategies are described in
detail in the Statement of Additional Information, which is referred to on the
back cover of this Prospectus.

                                      -9-
<PAGE>
 
     RISK FACTORS.  The principal risks of investing in the Fund are also
described above in the Risk/Return Summary. The following supplements that
description.

     Interest Rate Risk.  Generally, a fixed-income security will increase in
value when interest rates fall and decrease in value when interest rates rise.
As a result, if interest rates were to change rapidly, there is a risk that the
change in market value of the Fund's assets may not enable the Fund to maintain
a stable net asset value of $1.00 per share.

     Credit Risk.  The risk that an issuer will be unable to make principal and
interest payments when due is known as "credit risk."  U.S. government
securities are generally considered to be the safest type of investment in terms
of credit risk.

         

     Year 2000.  Like other mutual funds, financial and business organizations
and individuals around the world, the Fund could be adversely affected if the
computer systems used by the Adviser and the Fund's other service providers, or
persons with whom they deal, do not properly process and calculate date-related
information and data from and after January 1, 2000.  This possibility is
commonly known as the "Year 2000 Problem."  The Fund has been advised by the
Adviser, the Administrators and the Custodian that they are actively taking
steps to address the Year 2000 Problem with respect to the computer systems that
they use and to obtain assurances that comparable steps are being taken by the
Fund's other major service providers.  While there can be no assurance that the
Fund's service providers will be Year 2000 compliant, the Fund's service
providers expect that their plans to be compliant will be achieved.


                             MANAGEMENT OF THE FUND

INVESTMENT ADVISER
    
     The Adviser, a wholly-owned indirect subsidiary of PNC Bank, serves as the
Fund's investment adviser.  The Adviser and its affiliates are one of the
largest U.S. bank managers of mutual funds, with assets currently under
management in excess of $46 billion.  BIMC (formerly known as PNC Institutional
Management Corporation or "PIMC") was organized in 1977 by PNC Bank to perform
advisory services for investment companies and has its principal offices at
Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, Delaware
19809.      
    
     As investment adviser, BIMC manages the Fund and is responsible for all
purchases and sales of the Fund's securities. For the investment advisory
services provided and expenses assumed by it, BIMC is entitled to receive a fee,
computed daily and payable monthly, based on the Fund's average net assets. BIMC
and PFPC, the co-administrator, may from time to time reduce the investment
advisory and administration fees otherwise payable to them or may reimburse the
Fund for its operating expenses. Any fees waived and any expenses reimbursed by
BIMC and PFPC with respect to a particular fiscal year are not recoverable. For
the fiscal year ended October 31, 1998, the Fund paid investment advisory fees
and administration fees each aggregating .08% (net of waivers) of its average
net assets. The services provided by BIMC and the fees payable by the Fund for
these      

                                      -10-

services are described further in the Statement of Additional Information under
"Management of the Funds."


                            SHAREHOLDER INFORMATION
                                        
PRICE OF FUND SHARES

     The Fund's net asset value per share for purposes of pricing purchase and
redemption orders is determined by PFPC Inc. ("PFPC"), the Funds co-
administrator, as of 12:00 noon and 4:00 P.M., Eastern time, on each day on
which both the New York Stock Exchange and the Federal Reserve Bank of
Philadelphia are open for business (a "Business Day"). The net asset value per
share of each class of the Fund's shares is calculated by adding the value of
all securities and other assets of the Fund that are allocable to a particular
class, subtracting liabilities charged to such class, and dividing the result by
the total number of outstanding shares of such class.  In computing net asset
value, the Fund uses the amortized cost method of valuation as described in the
Statement of Additional Information under "Additional Purchase and Redemption
Information."  Under the 1940 Act, the Fund may postpone the date of payment of
any redeemable security for up to seven days.

PURCHASE OF SHARES
    
     Fund shares are sold at the net asset value per share next determined after
confirmation of a purchase order by PFPC, which also serves as the Fund's
transfer agent. Purchase orders for shares are accepted only on Business Days
and must be transmitted to PFPC in Wilmington, Delaware by telephone (800-441-
7450; in Delaware: 302-791-5350) or through the Fund's computer access program.
Orders accepted before 12:00 noon, Eastern time, for which payment has been
received by PNC Bank, N.A. ("PNC Bank"), the Fund's custodian, will be executed
at 12:00 noon. Orders accepted after 12:00 noon and before 2:30 P.M., Eastern
time (or orders accepted earlier in the same day for which payment has not been
received by 12:00 noon), will be executed at 4:00 P.M., Eastern time, if payment
has been received by PNC Bank by that time. Orders received at other times, and
orders for which payment has not been received by 4:00 P.M., Eastern time, will
not be accepted, and notice thereof will be given to the institution placing the
order. (Payment for orders which are not received or accepted will be returned
after prompt inquiry to the sending institution.) The Fund may in its discretion
reject any order for shares.      

     Payment for Fund shares may be made only in federal funds or other funds
immediately available to PNC Bank.  The minimum initial investment by an
institution is $3 million for Treasury Trust Fund Shares and $5,000 for Treasury
Trust Fund Dollar Shares; however, broker-dealers and other institutional
investors may set a higher minimum for their customers.  There is no minimum
subsequent investment.  The Fund, at its discretion, may reduce the minimum
initial investment for Treasury Trust Fund Shares for specific institutions
whose aggregate relationship with the Provident Institutional Funds is
substantially equivalent to this $3 million minimum and warrants this reduction.

                                      -11-
<PAGE>
 
     Fund shares are sold and redeemed without charge by the Fund. Institutional
investors purchasing or holding Fund shares for their customer accounts may
charge customer fees for cash management and other services provided in
connection with their accounts. A customer should, therefore, consider the terms
of its account with an institution before purchasing Fund shares. An institution
purchasing or redeeming Fund shares on behalf of its customers is responsible
for transmitting orders to the Fund in accordance with its customer agreements.

     Conflict of interest restrictions may apply to an institution's receipt of
compensation paid by the Fund in connection with the investment of fiduciary
funds in Treasury Trust Fund Dollar Shares.  (See also "Management of the Fund -
- - Service Organizations," as described in the Statement of Additional
Information.)  Institutions, including banks regulated by the Comptroller of the
Currency and investment advisers and other money managers subject to the
jurisdiction of the SEC, the Department of Labor or state securities
commissions, are urged to consult their legal advisors before investing
fiduciary funds in Treasury Trust Fund Dollar Shares.  (See also "Management of
the Fund -- Banking Laws," as described in the Statement of Additional
Information.)

REDEMPTION OF SHARES

     Redemption orders must be transmitted to PFPC in Wilmington, Delaware in
the manner described under "Purchase of Shares."  Shares are redeemed at the net
asset value per share next determined after PFPC's receipt of the redemption
order.  While the Fund intends to use its best efforts to maintain its net asset
value per share at $1.00, the proceeds paid to a shareholder upon redemption may
be more or less than the amount invested depending upon a share's net asset
value at the time of redemption.  Call 1-800-441-7450 (in Delaware: 302-791-
5350) to place redemption orders.

     Payment for redeemed shares for which a redemption order is received by
PFPC by 2:30 P.M., Eastern time, on a Business Day is normally made in federal
funds wired to the redeeming shareholder on the same day.  Payment for
redemption orders which are received between 2:30 P.M. and 4:00 P.M., Eastern
time, or on a day when PNC Bank is closed, is normally wired in federal funds on
the next day following redemption that PNC Bank is open for business.

     The Fund shall have the right to redeem shares in any account if the value
of the account is less than $1,000 after sixty-days' prior written notice to the
shareholder.  Any such redemption shall be effected at the net asset value next
determined after the redemption order is entered.  If during the sixty-day
period the shareholder increases the value of its account to $1,000 or more, no
such redemption shall take place.  Moreover, if a shareholders Treasury Trust
Shares account falls below an average of $100,000 in any particular calendar
month, the account may be charged an account maintenance fee with respect to
that month.  In addition, the Fund may also redeem shares involuntarily under
certain special circumstances described in the Statement of Additional
Information under "Additional Purchase and Redemption Information."

SHAREHOLDER SERVICE PLAN

     Institutional investors, such as banks, savings and loan associations and
other financial institutions, including affiliates of PNC Bank Corp.  ("Service
Organizations"), may purchase Dollar Shares.  Treasury Trust Fund Dollar Shares
are identical in all respects to Treasury Trust Fund Shares except that they
bear the service fees described below and enjoy certain exclusive voting rights
on matters relating to these fees.  The Fund will enter into an agreement with
each Service Organization which purchases Dollar Shares requiring it to provide
support services to its customers who are the beneficial owners of such shares
in consideration of the Fund's payment of .25% (on an annualized basis) of the
average daily net asset value of the Dollar Shares held by the Service
Organization for the benefit of customers.  Such services, which are described
more fully in the Statement of Additional Information under "Management of the
Fund  Service Organizations," include aggregating and processing purchase and
redemption requests from customers and placing net purchase and redemption
orders with PFPC; processing dividend payments from the Fund on behalf of
customers; providing information periodically to customers showing their
positions in Dollar Shares; and providing sub-accounting or the information
necessary for sub-accounting with respect to Dollar Shares beneficially owned by
customers.  Under the terms of the agreements, Service Organizations are
required to provide to their customers a schedule of any fees that they may
charge customers in connection with their investments in Dollar Shares.
Treasury Trust Fund Shares are sold to institutions that have not entered into
servicing agreements with the Fund in connection with their investments.

DIVIDENDS AND DISTRIBUTIONS

     The Fund declares dividends daily and distributes substantially all of its
net investment income to shareholders monthly.  Shares begin accruing dividends
on the day the purchase order for the shares is effected and continue to accrue
dividends through the day before such shares are redeemed.  Dividends are paid
monthly by check, or by wire transfer if requested in writing by the
shareholder, within five business days after the end of the month or within five
business days after a redemption of all of a shareholder's shares of a
particular class.

     Dividends are determined in the same manner for each class of shares of the
Fund.  Treasury Trust Fund Dollar Shares bear all the expense of fees paid to
Service Organizations, and as a result, at any given time, the dividend on
Treasury Trust Fund Dollar Shares will be approximately .25% lower than the
dividend on Treasury Trust Fund Shares.

     Institutional shareholders may elect to have their dividends reinvested in
additional full and fractional shares of the same class of shares with respect
to which such dividends are declared at the net asset value of such shares on
the payment date.  Reinvested dividends receive the same tax treatment as
dividends paid in cash.  Reinvestment elections, and any revocations thereof,
must be made in writing to PFPC, the Fund's transfer agent, at P.O. Box 8950,
Wilmington, Delaware 19885-9628 and will become effective after its receipt by
PFPC with respect to dividends paid.

TAXES

         
    
     The Fund's distributions will generally be taxable to shareholders. The 
Fund expects that all, or substantially all, of its distributions will consist 
of ordinary income. You will be subject to income tax on these distributions 
regardless whether they are paid in cash or reinvested in additional shares. 
     
    
     To the extent permissible by federal and state law, the Fund is structured 
to provide shareholders with income that is exempt or excluded from taxation at 
the state and local level. Substantially all dividends paid to shareholders 
residing in certain states will be exempt or excluded from state income tax. 
Many states, by statute, judicial decision or administrative action, have taken 
the position that dividends of a regulated investment company such as the Fund 
that are attributable to interest on direct U.S. Treasury obligations are the 
functional equivalent of interest from such obligations and are, therefore, 
exempt from state and local income taxes. Investors should be aware of the 
application of their state and local tax laws to investments in the Fund.      
    
     PFPC, as transfer agent, will send each Fund shareholder or its authorized 
representative an annual statement designating the amount, if any, of any 
dividends and distributions made during each year and their federal tax 
treatment.      
    
     Dividends declared in December of any year, and payable to shareholders of 
record on a specified date in December, will be deemed to have been received by 
the shareholders and paid by the Fund on December 31 of such year in the event 
such dividends are actually paid during January of the following year.      
    
     You should consult your tax adviser for further information regarding the 
federal, state and local tax consequences with respect to your specific 
situation.

                              RISK/RETURN SUMMARY
                                        
     
INVESTMENT GOAL:              The Fund seeks current income with liquidity and
                              stability of principal.     
    
INVESTMENT POLICIES:          The Fund invests in obligations issued or
                              guaranteed as to principal and interest by the
                              U.S. government or by its agencies or
                              instrumentalities thereof the interest income from
                              which, under current law, generally may not be
                              subject to state income tax by reason of federal
                              law.     
    
PRINCIPAL RISKS OF INVESTING: Securities issued or guaranteed by the U.S.
                              Government, its agencies and instrumentalities
                              have historically involved little risk of loss of
                              principal if held to maturity. However, due to
                              fluctuations in interest rates, the market value
                              of such securities may vary during the period a
                              shareholder owns shares of the Fund. While the
                              Fund seeks to maintain a constant net asset value
                              of $1.00 per share, the Fund is subject to risks
                              related to changes in prevailing interest rates,
                              since generally, a fixed-income security will
                              increase in value when interest rates fall and
                              decrease in value when interest rates rise.     

                              The Fund may from time to time engage in portfolio
                              trading for liquidity purposes, in order to
                              enhance its yield or if otherwise deemed
                              advisable. In selling securities prior to
                              maturity, the Fund may realize a price higher or
                              lower than that paid to acquire any given
                              security, depending upon whether interest rates
                              have decreased or increased since its acquisition.
                              In addition, shareholders in a particular state
                              that imposes an income tax should determine
                              through consultation with their own tax advisors
                              whether such interest income, when distributed by
                              the Fund, will be considered by the state to have
                              retained exempt status, and whether the Fund's
                              capital gain and other income, if any, when

                                       investment at $1.00 per share, it is
                                       possible to lose money by investing in
                                       the Fund.

WHO MAY WANT TO INVEST IN THE FUND:    The Fund is designed for institutional
                                       investors seeking current income with
                                       liquidity and security of principal. The
                                       Fund is particularly suitable for banks,
                                       corporations and other financial
                                       institutions that seek investment of
                                       short-term funds for their own accounts
                                       or for the accounts of their customers.

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods.  The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same.  Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                   INVESTMENT STRATEGIES AND RISK DISCLOSURE
                                        
     The Fund is a money market fund.  The investment objective of the Fund is
to seek current income with liquidity and security of principal.  The Fund's
investment objective may be changed by the Board of Trustees without shareholder
approval.  The Fund invests in obligations issued or guaranteed as to principal
and interest by the U.S. Government or by agencies or instrumentalities thereof
the interest income from which, under current law, generally may not be subject
to state income tax by reason of federal law.
    
     The Fund invests in securities maturing within 13 months or less from
the date of purchase, with certain exceptions.  For example, certain government
securities held by the Fund may have remaining maturities exceeding 13 months if
such securities provide for adjustments in their interest rates not less
frequently than every 13 months.  The securities purchased by the Fund are also
subject to the quality, diversification, and other requirements of Rule 2a-7
under the Investment Company Act of 1940, as amended, and other rules of the
Securities and Exchange Commission.     
    
     INVESTMENTS.  The Fund's investments may include the following:     

     U.S. Government Obligations.  The Fund may purchase obligations issued or
guaranteed by the U.S. Government, including securities issued by the U.S.
Treasury and by certain agencies or instrumentalities such as the Federal Home
Loan Bank, Federal Farm Credit Banks Funding Corp. and the Student Loan
Marketing Association, and related custodial receipts.
    
     Investment Company Securities.  The Fund may invest in securities issued by
other open-end investment companies that invest in the type of obligations in
which the Fund may invest and that determine their net asset value per share
based upon the amortized cost or penny rounding method.  Investments in the 
securities of other investment companies will cause the Fund (and, indirectly 
the Fund's shareholders) to bear proportionately the costs incurred in 
connection with the other investment companies' operations.     

     When-Issued and Delayed Settlement Transactions.  The Fund may purchase
securities on a "when-issued" or "delayed settlement" basis.  The Fund expects
that commitments to purchase when-issued or delayed settlement securities will
not exceed 25% of the value of its total assets absent unusual market
conditions.  The Fund does not intend to purchase when-issued or delayed
settlement securities for speculative purposes but only in furtherance of its
investment objective.

     Other Types of Investments.  This Prospectus describes the Fund's
principal investment strategies, and the particular types of securities in which
the Fund principally invests.  The Fund may, from time to time, make other types
of investments and pursue other investment strategies in support of its overall
investment goal.  These supplemental investment strategies are described in
detail in the Statement of Additional Information, which is referred to on the
back cover of this Prospectus.

                                      -8-
<PAGE>
 
     RISK FACTORS.  The principal risks of investing in the Fund are also
described above in the Risk/Return Summary. The following supplements that
description.

     Interest Rate Risk.  Generally, a fixed-income security will increase in
value when interest rates fall and decrease in value when interest rates rise.
As a result, if interest rates were to change rapidly, there is a risk that the
change in market value of the Fund's assets may not enable the Fund to maintain
a stable net asset value of $1.00 per share.

     Credit Risk.  The risk that an issuer will be unable to make principal and
interest payments when due is known as "credit risk."  U.S. Government
securities are generally considered to be the safest type of investment in terms
of credit risk.  Not all U.S. Government Securities are backed by the full faith
and credit of the United States.  Obligations of certain agencies and
instrumentlities of the U.S. Government are backed by the full faith and credit
of the United States; others are backed by the right of the issuer to borrow
from the U.S. Treasury or are backed only by the credit of the agency or
instrumentality issuing the obligation.

         

     Year 2000.  Like other mutual funds, financial and business organizations
and individuals around the world, the Fund could be adversely affected if the
computer systems used by the Adviser and the Fund's other service providers, or
persons with whom they deal, do not properly process and calculate date-related
information and data from and after January 1, 2000.  This possibility is
commonly known as the "Year 2000 Problem."  The Fund has been advised by the
Adviser, the Administrators and the Custodian that they are actively taking
steps to address the Year 2000 Problem with respect to the computer systems that
they use and to obtain assurances that comparable steps are being taken by the
Fund's other major service providers.  While there can be no assurance that the
Fund's service providers will be Year 2000 compliant, the Fund's service
providers expect that their plans to be compliant will be achieved.


                            MANAGEMENT OF THE FUND

INVESTMENT ADVISER
    
     The Adviser, a wholly-owned indirect subsidiary of PNC Bank, serves as the
Fund's investment adviser.  The Adviser and its affiliates are one of the
largest U.S. bank managers of mutual funds, with assets currently under
management in excess of $46 billion.  BIMC (formerly known as PNC Institutional
Management Corporation or "PIMC") was organized in 1977 by PNC Bank to perform
advisory services for investment companies and has its principal offices at
Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, Delaware
19809.     

     As investment adviser, BIMC manages the Fund and is responsible for all
purchases and sales of the Fund's securities.  For the investment advisory
services provided and expenses assumed by it, BIMC is entitled to receive a fee,
computed daily and payable monthly, based on the Fund's average net assets.
BIMC and PFPC, the co-administrator, may from time to time reduce the investment
advisory and administration fees otherwise payable to them or may reimburse the
Fund for its operating expenses.  Any fees waived and any expenses reimbursed by
BIMC and

                                      -9-
<PAGE>
     
PFPC with respect to a particular fiscal year are not recoverable. For the
fiscal year ended October 31, 1998, the Fund paid investment advisory fees and
administration fees each aggregating .08% (net of waivers) of its average net
assets. The services provided by BIMC and the fees payable by the Fund for these
services are described further in the Statement of Additional Information under
"Management of the Funds."    


                            SHAREHOLDER INFORMATION

PRICE OF FUND SHARES

     The Fund's net asset value per share for purposes of pricing purchase and
redemption orders is determined by PFPC Inc. ("PFPC"), the Funds co-
administrator, as of 12:00 noon and 4:00 P.M., Eastern time, on each day on
which both the New York Stock Exchange and the Federal Reserve Bank of
Philadelphia are open for business (a "Business Day"). The net asset value per
share of each class of the Fund's shares is calculated by adding the value of
all securities and other assets of the Fund that are allocable to a particular
class, subtracting liabilities charged to such class, and dividing the result by
the total number of outstanding shares of such class.  In computing net asset
value, the Fund uses the amortized cost method of valuation as described in the
Statement of Additional Information under "Additional Purchase and Redemption
Information."  Under the 1940 Act, the Fund may postpone the date of payment of
any redeemable security for up to seven days.

PURCHASE OF SHARES
    
     Fund shares are sold at the net asset value per share next determined after
confirmation of a purchase order by PFPC, which also serves as the Fund's
transfer agent. Purchase orders for shares are accepted only on Business Days
and must be transmitted to PFPC in Wilmington, Delaware by telephone (800-441-
7450; in Delaware: 302-791-5350) or through the Fund's computer access program.
Orders accepted before 12:00 noon, Eastern time, for which payment has been
received by PNC Bank, N.A. ("PNC Bank"), the Fund's custodian, will be executed
at 12:00 noon. Orders accepted after 12:00 noon and before 2:30 P.M., Eastern
time (or orders accepted earlier in the same day for which payment has not been
received by 12:00 noon), will be executed at 4:00 P.M., Eastern time, if payment
has been received by PNC Bank by that time. Orders received at other times, and
orders for which payment has not been received by 4:00 P.M., Eastern time, will
not be accepted, and notice thereof will be given to the institution placing the
order. (Payment for orders which are not received or accepted will be returned
after prompt inquiry to the sending institution.) The Fund may in its discretion
reject any order for shares.     

     Payment for Fund shares may be made only in federal funds or other funds
immediately available to PNC Bank.  The minimum initial investment by an
institution is $3 million for Federal Trust Fund Shares and $5,000 for Federal
Trust Fund Dollar Shares; however, broker-dealers and other institutional
investors may set a higher minimum for their customers.  There is no minimum
subsequent investment.  The Fund, at its discretion, may reduce the minimum
initial investment for Federal Trust Fund Shares for specific institutions whose
aggregate

                                      -10-
<PAGE>
 
relationship with the Provident Institutional Funds is substantially equivalent
to this $3 million minimum and warrants this reduction.

     Fund shares are sold and redeemed without charge by the Fund.
Institutional investors purchasing or holding Fund shares for their customer
accounts may charge customer fees for cash management and other services
provided in connection with their accounts.  A customer should, therefore,
consider the terms of its account with an institution before purchasing Fund
shares.  An institution purchasing or redeeming Fund shares on behalf of its
customers is responsible for transmitting orders to the Fund in accordance with
its customer agreements.

     Conflict of interest restrictions may apply to an institution's receipt of
compensation paid by the Fund in connection with the investment of fiduciary
funds in Federal Trust Fund Dollar Shares.  (See also "Management of the Fund --
Service Organizations," as described in the Statement of Additional
Information.)  Institutions, including banks regulated by the Comptroller of the
Currency and investment advisers and other money managers subject to the
jurisdiction of the SEC, the Department of Labor or state securities
commissions, are urged to consult their legal advisors before investing
fiduciary funds in Federal Trust Fund Dollar Shares.  (See also "Management of
the Fund -- Banking Laws," as described in the Statement of Additional
Information).

REDEMPTION OF SHARES

     Redemption orders must be transmitted to PFPC in Wilmington, Delaware in
the manner described under "Purchase of Shares."  Shares are redeemed at the net
asset value per share next determined after PFPC's receipt of the redemption
order.  While the Fund intends to use its best efforts to maintain its net asset
value per share at $1.00, the proceeds paid to a shareholder upon redemption may
be more or less than the amount invested depending upon a share's net asset
value at the time of redemption.  Call 1-800-441-7450 (in Delaware: 302-791-
5350) to place redemption orders.

     Payment for redeemed shares for which a redemption order is received by
PFPC by 2:30 P.M., Eastern time, on a Business Day is normally made in federal
funds wired to the redeeming shareholder on the same day.  Payment for
redemption orders which are received between 2:30 P.M. and 4:00 P.M., Eastern
time, or on a day when PNC Bank is closed, is normally wired in federal funds on
the next day following redemption that PNC Bank is open for business.

     The Fund shall have the right to redeem shares in any account if the value
of the account is less than $1,000 after sixty-days' prior written notice to the
shareholder.  Any such redemption shall be effected at the net asset value next
determined after the redemption order is entered.  If during the sixty-day
period the shareholder increases the value of its account to $1,000 or more, no
such redemption shall take place.  Moreover, if a shareholder's Federal Trust
Fund Shares account falls below an average of $100,000 in any particular
calendar month, the account may be charged an account maintenance fee with
respect to that month.  In addition, the Fund may also

                                      -11-

redeem shares involuntarily under certain special circumstances described in the
Statement of Additional Information under "Additional Purchase and Redemption
Information."

SHAREHOLDER SERVICE PLAN

     Institutional investors, such as banks, savings and loan associations and
other financial institutions, including affiliates of PNC Bank Corp.  ("Service
Organizations"), may purchase Dollar Shares.  Federal Trust Fund Dollar Shares
are identical in all respects to Federal Trust Fund Shares except that they bear
the service fees described below and enjoy certain exclusive voting rights on
matters relating to these fees.  The Fund will enter into an agreement with each
Service Organization which purchases Dollar Shares requiring it to provide
support services to its customers who are the beneficial owners of such shares
in consideration of the Fund's payment of .25% (on an annualized basis) of the
average daily net asset value of the Dollar Shares held by the Service
Organization for the benefit of customers.  Such services, which are described
more fully in the Statement of Additional Information under "Management of the
Fund  Service Organizations," include aggregating and processing purchase and
redemption requests from customers and placing net purchase and redemption
orders with PFPC; processing dividend payments from the Fund on behalf of
customers; providing information periodically to customers showing their
positions in Dollar Shares; and providing sub-accounting or the information
necessary for sub-accounting with respect to Dollar Shares beneficially owned by
customers.  Under the terms of the agreements, Service Organizations are
required to provide to their customers a schedule of any fees that they may
charge customers in connection with their investments in Dollar Shares.  Federal
Trust Fund Shares are sold to institutions that have not entered into servicing
agreements with the Fund in connection with their investments.

DIVIDENDS AND DISTRIBUTIONS

     The Fund declares dividends daily and distributes substantially all of its
net investment income to shareholders monthly.  Shares begin accruing dividends
on the day the purchase order for the shares is effected and continue to accrue
dividends through the day before such shares are redeemed.  Dividends are paid
monthly by check, or by wire transfer if requested in writing by the
shareholder, within five business days after the end of the month or within five
business days after a redemption of all of a shareholder's shares of a
particular class.

     Dividends are determined in the same manner for each class of shares of the
Fund.  Federal Trust Fund Dollar Shares bear all the expense of fees paid to
Service Organizations, and as a result, at any given time, the dividend on
Federal Trust Fund Dollar Shares will be approximately .25% lower than the
dividend on Federal Trust Fund Shares.

     Institutional shareholders may elect to have their dividends reinvested in
additional full and fractional shares of the same class of shares with respect
to which such dividends are declared at the net asset value of such shares on
the payment date.  Reinvested dividends receive the same tax treatment as
dividends paid in cash.  Reinvestment elections, and any revocations thereof,
must be made in writing to PFPC, the Fund's transfer agent, at P.O. Box 8950,

                                      -12-

Wilmington, Delaware 19885-9628 and will become effective after its receipt by
PFPC with respect to dividends paid.

TAXES
         
    
     The Fund's distributions will generally be taxable to shareholders. The
Fund expects that all, or substantially all, of its distributions will consist
of ordinary income. You will be subject to income tax on these distributions
regardless whether they are paid in cash or reinvested in additional shares. 
     
    
     To the extent permissible by federal and state law, the Fund is structured 
to provide shareholders with income that is exempt or excluded from taxation at 
the state and local level.  Substantially all dividends paid to shareholders 
residing in certain states will be exempt or excluded from state income tax.  
Many states, by statute, judicial decision or administrative action, have taken 
the position that dividends of a regulated investment company such as the Fund 
that are attributable to interest on obligations of the U.S. Treasury and 
certain U.S. Government agencies and instrumentalities are the functional 
equivalent of interest from such obligations and are, therefore, exempt from 
state and local income taxes.  Investors should be aware of the application of 
their state and local tax laws to investments in the Fund.     
    
     PFPC, as transfer agent, will send each Fund shareholder or its authorized 
representative an annual statement designating the amount, if any, of any 
dividends and distributions made during each year and their federal tax 
treatment.     
    
     Dividends declared in December of any year, and payable to shareholders of 
record on a specified date in December, will be deemed to have been received by 
the shareholders and paid by the Fund on December 31 of such year in the event 
such dividends are actually paid during January of the following year.     
    
     You should consult your tax adviser for further information regarding the 
federal, state and local tax consequences with respect to your specific 
situation.

                              RISK/RETURN SUMMARY

    
INVESTMENT GOAL:              The Fund seeks as high a level of current interest
                              income exempt from federal income tax as is
                              consistent with relative stability of principal.
     
    
INVESTMENT POLICIES:          The Fund invests in a broad range of short-term
                              tax-exempt obligations issued by or on behalf of
                              states, territories, and possessions of the United
                              States, the District of Columbia, and their
                              respective authorities, agencies,
                              instrumentalities, and political subdivisions and
                              tax-exempt derivative securities such as tender
                              option bonds, participations, beneficial interests
                              in trusts and partnership interests (collectively,
                              "Municipal Obligations").       
    
PRINCIPAL RISKS OF INVESTING: Although the Fund invests in money market
                              instruments which the investment adviser,
                              BlackRock Institutional Management Corporation
                              ("BIMC," or the "Adviser") believes present
                              minimal credit risks at the time of purchase,
                              there is a risk that an issuer may not be able to
                              make principal and interest payments when due.
                              While the Fund seeks to maintain a constant net
                              asset value of $1.00 per share, the Fund is also
                              subject to risks related to changes in prevailing
                              interest rates, since generally, a fixed-income
                              security will increase in value when interest
                              rates fall and decrease in value when interest
                              rates rise.

                              An investment in the Fund is not a deposit in PNC
                              Bank, N.A. and is not insured or guaranteed by the
                              Federal Deposit Insurance Corporation or any other
                              government agency.  Although the Fund seeks to
                              preserve the value of your investment at $1.00 per
                              share, it is possible to lose money by investing
                              in the Fund.

WHO MAY WANT TO INVEST IN     The Fund is designed for institutional investors

but can terminate the waivers upon 120 days prior written notice to the Fund.

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods.  The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same.  Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                   INVESTMENT STRATEGIES AND RISK DISCLOSURE

     The Fund is a money market fund. The investment objective of the Fund is to
seek as high a level of current interest income exempt from federal income tax
as is consistent with relative stability of principal. The Fund's investment
objective may be changed by the Board of Trustees without shareholder approval.
The Fund invests substantially all its assets in a diversified portfolio of
Municipal Obligations. The Fund will not knowingly purchase securities the
interest on which is subject to regular federal income tax.
    
     Except during periods of unusual market conditions or during temporary
defensive periods, the Fund invests substantially all, but in no event less than
80% of its total assets in Municipal Obligations with remaining maturities of 13
months or less as determined in accordance with the rules of the Securities and
Exchange Commission. The Fund may hold uninvested cash reserves pending
investment, during temporary defensive periods or if, in the opinion of the
Adviser, suitable tax-exempt obligations are unavailable. There is no percentage
limitation on the amount of assets which may be held uninvested. Uninvested cash
reserves will not earn income. The securities purchased by the Fund are also
subject to the quality, diversification, and other requirements of Rule 2a-7
under the Investment Company Act of 1940, as amended, and other rules of the
SEC. Pursuant to Rule 2a-7, the Fund generally will limit its purchase of any
one issuer's securities (other than U.S. Government securities, repurchase
agreements collaterialized by such securities and securities subject to certain
guarantees or otherwise providing a right to demand payment) to 5% of the Fund's
total assets, except that up to 25% of its total assets may be invested in the
securities of one issuer for a period of up to three business days; provided
that the Fund may not invest more than 25% of its total assets in the securities
of more than one issuer in accordance with the foregoing at any one time.      
    
     The Fund will only purchase securities that present minimal credit risk as
determined by the Adviser pursuant to guidelines approved by the Board of
Trustees of Provident Institutional Funds. Securities purchased by the Fund (or
the issuers of such securities) will be First Tier Eligible Securities.
Applicable First Tier Eligible Securities are:     
         
     .    securities that have short-term debt ratings at the time of purchase
          (or which are guaranteed or in some cases otherwise supported by 
          guarantees or other credit supports with such ratings) in the highest
          rating category by at least two unaffiliated nationally recognized
          statistical rating organizations ("NRSROs") (or one NRSRO if the
          security or guarantee was rated by only one NRSRO);     
         
     .    securities that are issued or guaranteed by a person with such 
          ratings;      
         
     .    securities without such short-term ratings that have been determined
          to be of comparable quality by the Adviser pursuant to guidelines
          approved by the Board of Trustees; or       
         
     .    securities issued by other open-end investment companies that invest 
          in the type of obligations in which the Fund may invest.

     INVESTMENTS.  The Fund's investments may include the following:       
    
     Municipal Obligations.  The Fund may purchase Municipal Obligations which
are classified as "general obligation" securities and "revenue" securities.
Revenue securities include private activity bonds which are not payable from the
unrestricted revenues of the issuer.  Consequently, the credit quality of 
private activity bonds is usually directly related to the credit standing of the
corporate user of the facility involved. While interest paid on private activity
bonds will be exempt from regular federal income tax, it may be treated as a
specific tax preference item under the federal alternative minimum tax. The
portfolio may also include "moral obligation" bonds.     
    
     Investment Company Securities.  The Fund may invest in securities issued by
other open-end investment companies that invest in the type of obligations in
which the Fund may invest and that determine their net asset value per share
based upon the amortized cost or penny rounding method. Investments in the
securities of other investment companies will cause the Fund (and, indirectly
the Fund's shareholders) to bear proportionately the costs incurred in
connection with the other investment companies' operations.     
    
     Variable and Floating Rate Instruments. The Fund may purchase variable or
floating rate notes, which are instruments that provide for adjustments in the
interest rate on certain reset dates or whenever a specified interest rate index
changes, respectively.       

     When-Issued and Delayed Settlement Transactions.  The Fund may purchase
Municipal Obligations on a "when-issued" or "delayed settlement" basis.  The
Fund expects that commitments to purchase when-issued or delayed settlement
securities will not exceed 25% of the value of its total assets absent unusual
market conditions.  The Fund does not intend to purchase when-issued or delayed
settlement securities for speculative purposes but only in furtherance of its
investment objective.

     Stand-by Commitments.  The Fund may acquire "stand-by commitments" with
respect to Municipal Obligations held in its portfolio.  The Fund will acquire
stand-by commitments solely to facilitate portfolio liquidity and does not
intend to exercise its rights thereunder for trading purposes.
    
     Illiquid Securities.  The Fund will not invest more than 10% of the value
of its total assets in illiquid securities, including time deposits and
repurchase agreements having maturities longer than seven days. Securities that
have readily available market quotations are not deemed illiquid for purposes of
this limitation.       

     Other Types of Investments.  This Prospectus describes the Fund's
principal investment strategies, and the particular types of securities in which
the Fund principally invests.  The Fund may, from time to time, make other types
of investments and pursue other investment strategies in support of its overall
investment goal.  These supplemental investment strategies are described in
detail in the Statement of Additional Information, which is referred to on the
back cover of this Prospectus.

     RISK FACTORS. The principal risks of investing in the Fund are also
described above in the Risk/Return Summary. The following supplements that
description.

     Interest Rate Risk.  Generally, a fixed-income security will increase in
value when interest rates fall and decrease in value when interest rates rise.
As a result, if interest rates were to change rapidly, there is a risk that the
change in market value of the Fund's assets may not enable the Fund to maintain
a stable net asset value of $1.00 per share.

     Credit Risk.  The risk that an issuer will be unable to make principal and
interest payments when due is known as "credit risk."  U.S. government
securities are generally considered to be the safest type of investment in terms
of credit risk.  Municipal obligations generally rank between U.S. government
securities and corporate debt securities in terms of credit safety.  Credit
quality ratings published by an NRSRO are widely accepted measures of credit
risk.  The lower a security is rated by an NRSRO, the more credit risk it is
considered to represent.
    
     Other Risks.  Certain investment strategies employed by the Fund may 
involve additional investment risk. Liquidity risk involves certain 
securities which may be difficult or impossible to sell at the time and the 
price that the Fund would like.      

     Municipal Obligations.  Opinions relating to the validity of Municipal
Obligations and to the exemption of interest thereon from federal income tax are
rendered by bond counsel to the respective issuers at the time of issuance, and
opinions relating to the validity of and the tax-exempt status of payments
received by the Fund for tax-exempt derivative securities are rendered by
counsel to the respective sponsors of such securities.  The Adviser will rely on
such opinions and will not review independently the underlying proceedings
relating to the issuance of Municipal Obligations, the creation of any tax-
exempt derivative securities, or the bases for such opinions.

     Year 2000.  Like other mutual funds, financial and business organizations
and individuals around the world, the Fund could be adversely affected if the
computer systems used by the Adviser and the Fund's other service providers, or
persons with whom they deal, do not properly process and calculate date-related
information and data from and after January 1, 2000.  This possibility is
commonly known as the "Year 2000 Problem."  The Fund has been advised by the
Adviser, the Administrators and the Custodian that they are actively taking
steps to address the Year 2000 Problem with respect to the computer systems that
they use and to obtain assurances that comparable steps are being taken by the
Fund's other major service providers.  While there can be assurance that the
Fund's service providers will be Year 2000 compliant, the Fund's service
providers expect that their plans to be compliant will be achieved.

                            MANAGEMENT OF THE FUND

INVESTMENT ADVISER
    
     The Adviser, a wholly-owned indirect subsidiary of PNC Bank, serves as the
Fund's investment adviser.  The Adviser, with its affiliates, is one of the
largest U.S. bank managers of mutual funds, with assets currently under
management in excess of $46 billion.  BIMC (formerly known as PNC Institutional
Management Corporation or "PIMC") was organized in 1977 by PNC Bank to perform
advisory services for investment companies and has its principal offices at
Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, Delaware
19809.       
    
     As investment adviser, BIMC manages the Fund and is responsible for all
purchases and sales of the Fund's securities. For the investment advisory
services provided and expenses assumed by it, BIMC is entitled to receive a fee,
computed daily and payable monthly, based on the Fund's average net assets. BIMC
and PFPC, the co-administrator, may from time to time reduce the investment
advisory and administration fees otherwise payable to them or may reimburse the
Fund for its operating expenses. Any fees waived and any expenses reimbursed by
BIMC and PFPC with respect to a particular fiscal year are not recoverable. For
the fiscal year ended November 30, 1998, the Fund paid investment advisory fees
and administration fees each aggregating .09% (net of waivers) of its average
net assets. The services provided by BIMC and the fees payable by the Fund for
these services are described further in the Statement of Additional Information
under "Management of the Funds."       


                            SHAREHOLDER INFORMATION

PRICE OF FUND SHARES

     The Fund's net asset value per share for purposes of pricing purchase and
redemption orders is determined by PFPC Inc. ("PFPC"), the Funds co-
administrator, as of 12:00 noon and 4:00 P.M., Eastern time, on each day on
which both the New York Stock Exchange and the Federal Reserve Bank of
Philadelphia are open for business (a "Business Day"). The net asset value per
share of each class of the Fund's shares is calculated by adding the value of
all securities and other assets of the Fund that are allocable to a particular
class, subtracting liabilities charged to such class, and dividing the result by
the total number of outstanding shares of such class.  In computing net asset
value, the Fund uses the amortized cost method of valuation as described in the
Statement of Additional Information under "Additional Purchase and Redemption
Information."  Under the 1940 Act, the Fund may postpone the date of payment of
any redeemable security for up to seven days.

                                      -11-
<PAGE>
 
PURCHASE OF SHARES
    
     Fund shares are sold at the net asset value per share next determined after
confirmation of a purchase order by PFPC, which also serves as the Fund's
transfer agent. Purchase orders for shares are accepted only on Business Days
and must be transmitted to PFPC in Wilmington, Delaware by telephone (800-441-
7450; in Delaware: 302-791-5350) or through the Fund's computer access program.
Orders accepted before 12:00 noon, Eastern time, for which payment has been
received by PNC Bank, N.A. ("PNC Bank"), the Fund's custodian, will be executed
at 12:00 noon. Orders accepted after 12:00 noon and before 2:30 P.M., Eastern
time (or orders accepted earlier in the same day for which payment has not been
received by 12:00 noon), will be executed at 4:00 P.M., Eastern time, if payment
has been received by PNC Bank by that time. Orders received at other times, and
orders for which payment has not been received by 4:00 P.M., Eastern time, will
not be accepted, and notice thereof will be given to the institution placing the
order. (Payment for orders which are not received or accepted will be returned
after prompt inquiry to the sending institution.) The Fund may in its discretion
reject any order for shares.       

     Payment for Fund shares may be made only in federal funds or other funds
immediately available to PNC Bank. The minimum initial investment by an
institution is $3 million for MuniFund Shares; there is no minimum initial
investment for Administration Shares, Dollar Shares, Plus Shares, Cash Reserve
Shares or Cash Management Shares, however, broker-dealers and other
institutional investors may set a minimum for their customers. There is no
minimum subsequent investment. The Fund, at its discretion, may reduce the
minimum initial investment for MuniFund Shares for specific institutions whose
aggregate relationship with the Provident Institutional Funds is substantially
equivalent to this $3 million minimum and warrants this reduction.

     Fund shares are sold and redeemed without charge by the Fund.
Institutional investors purchasing or holding Fund shares for their customer
accounts may charge customer fees for cash management and other services
provided in connection with their accounts.  A customer should, therefore,
consider the terms of its account with an institution before purchasing Fund
shares.  An institution purchasing or redeeming Fund shares on behalf of its
customers is responsible for transmitting orders to the Fund in accordance with
its customer agreements.

     Conflict of interest restrictions may apply to an institution's receipt of
compensation paid by the Fund in connection with the investment of fiduciary
funds in MuniFund Administration Shares, MuniFund Dollar Shares, MuniFund Plus
Shares, MuniFund Cash Reserve Shares and MuniFund Cash Management Shares. (See
also "Management of the Fund -- Service Organizations," as described in the
Statement of Additional Information.) Institutions, including banks regulated by
the Comptroller of the Currency and investment advisers and other money managers
subject to the jurisdiction of the SEC, the Department of Labor or state
securities commissions, are urged to consult their legal advisors before
investing fiduciary funds in MuniFund Administration Shares, MuniFund Dollar
Shares, MuniFund Plus Shares, MuniFund Cash Reserve Shares and MuniFund Cash
Management Shares. (See also "Management of the Fund --Banking Laws," as
described in the Statement of Additional Information).

REDEMPTION OF SHARES

     Redemption orders must be transmitted to PFPC in Wilmington, Delaware in
the manner described under "Purchase of Shares."  Shares are redeemed at the net
asset value per share next determined after PFPC's receipt of the redemption
order.  While the Fund intends to use its best efforts to maintain its net asset
value per share at $1.00, the proceeds paid to a shareholder upon redemption may
be more or less than the amount invested depending upon a share's net asset
value at the time of redemption.  Call 1-800-441-7450 (in Delaware: 302-791-
5350) to place redemption orders.

     Payment for redeemed shares for which a redemption order is received by
PFPC by 12:00 P.M., Eastern time, on a Business Day is normally made in federal
funds wired to the redeeming shareholder on the same day.  Payment for
redemption orders which are received between 12:00 noon and 4:00 P.M., Eastern
time, or on a day when PNC Bank is closed, is normally wired in federal funds on
the next day following redemption that PNC Bank is open for business.

     The Fund shall have the right to redeem shares in any account if the value
of the account is less than $1,000 after sixty-days' prior written notice to the
shareholder. Any such redemption shall be effected at the net asset value next
determined after the redemption order is entered. If during the sixty-day period
the shareholder increases the value of its account to $1,000 or more, no such
redemption shall take place. Moreover, if a shareholder's MuniFund Shares
account falls below an average of $100,000 in any particular calendar month, the
account may be charged an account maintenance fee with respect to that month. In
addition, the Fund may also redeem shares involuntarily under certain special
circumstances described in the Statement of Additional Information under
"Additional Purchase and Redemption Information."

DISTRIBUTION AND SHAREHOLDER SERVICE PLANS

     The Fund offers six classes of shares. The difference between the classes 
of shares is the fees borne by a class of shares pursuant to separate fee plans 
adopted by each class. MuniFund Shares do not bear any fees for distribution, 
servicing, shareholder servicing, sweep fees or cash sweep marketing services. 
The fees borne by the other classes are as follows:

     Service Fees are paid for general shareholder liaison services. Shareholder
Service Fees are paid for services relating to the processing and administration
of shareholder accounts. The Fund has adopted a plan pursuant to Rule 12b-1.
12b-1 Fees are paid for distribution and sales support, and shareholder
services. Cash Sweep Fees are paid for providing a sweep service into the Fund.
Cash Sweep Marketing Fees are paid for providing marketing administrative
activities in connection with the sweep program.     

     Shares of the Fund are not sold to individuals, but may be sold to the
following entities, which hold the shares for the accounts of their customers.
Administration Shares. Dollar Shares, Cash Reserve Shares and Cash Management
Shares are sold to institutional investors such as banks, saving and loan
associations, and other financial institutions, including affiliates of PNC Bank
Corp. ("Service Organizations"). Plus Shares are sold to broker-dealers. Because
fees associated with the distribution and/or shareholder service plans are paid
out of the Fund's assets on an ongoing basis, over time holders of the share
classes described above may pay more than the economic equivalent of the maximum
front-end sales charge permitted by NASD Regulation, Inc.

                                  -13-

DIVIDENDS AND DISTRIBUTIONS

     The Fund declares dividends daily and distributes substantially all of its
net investment income to shareholders monthly.  Shares begin accruing dividends
on the day the purchase order for the shares is effected and continue to accrue
dividends through the day before such shares are redeemed.  Dividends are paid
monthly by check, or by wire transfer if requested in writing by the
shareholder, within five business days after the end of the month or within five
business days after a redemption of all of a shareholder's shares of a
particular class.

     Institutional shareholders may elect to have their dividends reinvested in
additional full and fractional shares of the same class of shares with respect
to which such dividends are declared at the net asset value of such shares on
the payment date.  Reinvested dividends receive the same tax treatment as
dividends paid in cash.  Reinvestment elections, and any revocations thereof,
must be made in writing to PFPC, the Fund's transfer agent, at P.O. Box 8950,
Wilmington, Delaware 19885-9628 and will become effective after its receipt by
PFPC with respect to dividends paid.

TAXES
    
     The Fund's distributions will generally constitute tax-exempt income for 
shareholders for federal income tax purposes.  It is possible, depending upon 
the Fund's investments, that a portion of the Fund's distributions could be 
taxable to shareholders as ordinary income or capital gains, but the Fund does 
not expect that this will be the case.  Moreover, although the distributions are
exempt for federal income tax purposes, they will generally constitute taxable 
income for state and local income tax purposes except that, subject to 
limitations that vary depending on the state, distributions from interest paid 
by a state or municipal entity may be exempt from tax in that state.       
    
     Interest on indebtedness incurred by a shareholder to purchase or carry 
shares of the Fund generally will not be deductible for federal income tax 
purposes.       
    
     You should note that a portion of the exempt-interest dividends paid by 
the Fund may constitute an item of tax preference for purposes of determining
federal alternative minimum tax liability. Exempt-interest dividends will also
be considered along with other adjusted gross income in determining whether any
Social Security or railroad retirement payments received by you are subject to
federal income taxes.       
    
     PFPC, as transfer agent, will send each Fund shareholder or its authorized 
representative an annual statement designating the amount, if any, of any 
dividends and distributions made during each year and their federal tax 
treatment.       
    
     Dividends declared in December of any year, and payable to shareholders of 
record on a specified date in December, will be deemed to have been received by 
the shareholders and paid by the Fund on December 31 of such year in the event 
such dividends are actually paid during January of the following year.       
    
     You should also consult your tax adviser for further information regarding 
the federal, state and local tax consequences with respect to your specific 
situation.

                             FINANCIAL HIGHLIGHTS
    
The financial highlights tables are intended to help you understand the Fund's
financial performance for the past 5 years. Certain information reflects
financial results for a single Fund share. The total returns in the table
represent the rate that an investor would have earned or lost on an investment
in the Fund (assuming reinvestment of all dividends and distributions). This
information has been audited by KPMG LLP, whose report, along with the Fund's
financial statements, are incorporated by reference into the Statement of
Additional Information and included in the Annual Report, each of which is
available upon request. Administration Shares, Plus Shares, Cash Reserve Shares
and Cash Management Shares have not yet commenced operations, therefore no
financial information has been provided for these classes.

                              RISK/RETURN SUMMARY

    
INVESTMENT GOAL:              The Fund seeks as high a level of current interest
                              income exempt from federal income tax as is
                              consistent with relative stability of principal.
     
    
INVESTMENT POLICIES:          The Fund invests in a broad range of short-term 
                              tax-exempt obligations issued by or on behalf of
                              states, territories, and possessions of the United
                              States, the District of Columbia, and their
                              respective authorities, agencies, 
                              instrumentalities, and political subdivisions and
                              tax-exempt derivative securities such as tender
                              option bonds, participations, beneficial interests
                              in trusts and partnership interests (collectively,
                              "Municipal Obligations").      

    
PRINCIPAL RISKS OF INVESTING: Although the Fund invests in money market
                              instruments which the investment adviser,
                              BlackRock Institutional Management Corporation
                              ("BIMC," or the "Adviser") believes present
                              minimal credit risks at the time of purchase,
                              there is a risk that an issuer may not be able to
                              make principal and interest payments when due.
                              While the Fund seeks to maintain a constant net
                              asset value of $1.00 per share, the Fund is also
                              subject to risks related to changes in prevailing
                              interest rates, since generally, a fixed-income
                              security will increase in value when interest
                              rates fall and decrease in value when interest
                              rates rise.      

                              Although the Fund intends to invest its assets in
                              tax-exempt obligations, the Fund is permitted to
                              invest in private activity bonds and other
                              securities which may be subject to the federal
                              alternative minimum tax.
<PAGE>
 
                              An investment in the Fund is not a deposit in PNC
                              Bank, N.A. and is not insured or guaranteed by the
                              Federal Deposit Insurance Corporation or any other
                              government agency. Although the Fund seeks to
                              preserve the value of your investment at $1.00 per
                              share, it is possible to lose money by investing
                              in the Fund.

WHO MAY WANT TO INVEST IN     The Fund is designed for institutional investors 
THE FUND:                     seeking as high a level of current interest income
                              exempt from federal income tax as is consistent
                              with relative stability of principal. The Fund is
                              particularly suitable for banks, corporations and
                              other financial institutions that seek investment
                              of short-term funds for their own accounts or for
                              the accounts of their customers.

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods.  The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same.  Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                   INVESTMENT STRATEGIES AND RISK DISCLOSURE

     The Fund is a money market fund.  The investment objective of the Fund is
to seek as high a level of current interest income exempt from federal income
tax as is consistent with relative stability of principal.  The Fund's
investment objective may be changed by the Board of Trustees without shareholder
approval.  The Fund invests substantially all of its assets in a diversified
portfolio of Municipal Obligations.  The Fund will not knowingly purchase
securities the interest on which is subject to regular federal income tax.
    
     Except during periods of unusual market conditions or during temporary
defensive periods, the Fund invests substantially all, but in no event less
than 80% of its total assets in Municipal Obligations with remaining maturities
of 13 months or less as determined in accordance with the rules of the
Securities and Exchange Commission. The Fund may hold uninvested cash reserves
pending investment, during temporary defensive periods or if, in the opinion of
the Adviser, suitable tax-exempt obligations are unavailable. There is no
percentage limitation on the amount of assets which may be held uninvested.
Uninvested cash reserves will not earn income. The securities purchased by the
Fund are also subject to the quality, diversification, and other requirements of
Rule 2a-7 under the Investment Company Act of 1940, as amended, and other rules
of the SEC. Pursuant to Rule 2a-7, the Fund generally will limit its purchase of
any one issuer's securities (other than U.S. Government securities, repurchase
agreements collaterialized by such securities and securities subject to certain
guarantees or otherwise providing the right to demand payment) to 5% of the
Fund's total assets, except that up to 25% of its total assets may be invested
in the securities of one issuer for a period of up to three business days;
provided that the Fund may not invest more than 25% of its total assets in the
securities of more than one issuer in accordance with the foregoing at any one
time.      
    
     The Fund will only purchase securities that present minimal credit risk as
determined by the Adviser pursuant to guidelines approved by the Board of
Trustees of Provident Institutional Funds.  Securities purchased by the Fund (or
the issuers of such securities) will be Eligible Securities. Applicable Eligible
Securities are:      
    
     .    securities that have short-term debt ratings at the time of purchase
          (or which are guaranteed or in some cases otherwise supported by 
          guarantees or other credit supports with such ratings) in the two
          highest rating categories by at least two unaffiliated nationally
          recognized statistical rating organizations ("NRSROs") (or one NRSRO
          if the security or guarantee was rated by only one NRSRO);      
    
     .    securities that are issued or guaranteed by a person with such
          ratings;      
    
     .    securities without such short-term ratings that have been determined
          to be of comparable quality by the Adviser pursuant to guidelines
          approved by the Board of Trustees; or      
    
     .    shares of other open-end investment companies that invest in the type 
          of obligations in which the Fund may invest.      

                                      -6-
<PAGE>
    
     INVESTMENTS.  The Fund's investments may include the following:      
    
     Municipal Obligations.  The Fund may purchase Municipal Obligations which
are classified as "general obligation" securities and "revenue" securities.
Revenue securities include private activity bonds which are not payable from the
unrestricted revenues of the issuer.  Consequently, the credit quality of 
private activity bonds is usually directly related to the credit standing of the
corporate user of the facility involved.  While interest paid on private 
activity bonds will be exempt from regular federal income tax, it may be treated
as a specific tax preference item under the federal alternative minimum tax.  
The portfolio may also include "moral obligation" bonds.      
    
     Investment Company Securities.  The Fund may invest in securities issued by
other open-end investment companies that invest in the type of obligations in
which the Fund may invest and that determine their net asset value per share
based upon the amortized cost or penny rounding method.  Investments in the 
securities of other investment companies will cause the Fund (and, indirectly 
the Fund's shareholders) to bear proportionately the costs incurred in 
connection with the other investment companies' operations.      
    
     Variable and Floating Rate Instruments.  The Fund may purchase variable or
floating rate notes, which are instruments that provide for adjustments in the
interest rate on certain reset dates or whenever a specified interest rate index
changes, respectively.      

     When-Issued and Delayed Settlement Transactions.  The Fund may purchase
Municipal Obligations on a "when-issued" or "delayed settlement" basis.  The
Fund expects that commitments to purchase when-issued or delayed settlement
securities will not exceed 25% of the value of its total assets absent unusual
market conditions.  The Fund does not intend to purchase when-issued or delayed
settlement securities for speculative purposes but only in furtherance of its
investment objective.
    
     Illiquid Securities. The Fund will not invest more than 10% of the value of
its total assets in illiquid securities, including time deposits and repurchase
agreements having maturities longer than seven days. Securities that have
readily available market quotations are not deemed illiquid for purposes of this
limitation.      

     Stand-by Commitments.  The Fund may acquire "stand-by commitments" with
respect to Municipal Obligations held in its portfolio.  The Fund will acquire
stand-by commitments solely to facilitate portfolio liquidity and does not
intend to exercise its rights thereunder for trading purposes.

     Other Types of Investments.  This Prospectus describes the Fund's
principal investment strategies, and the particular types of securities in which
the Fund principally invests.  The Fund may, from time to time, make other types
of investments and pursue other investment strategies in support of its overall
investment goal.  These supplemental investment strategies are described in
detail in the Statement of Additional Information, which is referred to on the
back cover of this Prospectus.

     RISK FACTORS. The principal risks of investing in the Fund are also
described above in the Risk/Return Summary. The following supplements that
description.

    Interest Rate Risk.  Generally, a fixed-income security will increase in
value when interest rates fall and decrease in value when interest rates rise.
As a result, if interest rates were to change rapidly, there is a risk that the
change in market value of the Fund's assets may not enable the Fund to maintain
a stable net asset value of $1.00 per share.
 
     Credit Risk.  The risk that an issuer will be unable to make principal and
interest payments when due is known as "credit risk."  U.S. government
securities are generally considered to be the safest type of investment in terms
of credit risk.  Municipal obligations generally rank between U.S. government
securities and corporate debt securities in terms of credit safety.  Credit
quality ratings published by an NRSRO are widely accepted measures of credit
risk.  The lower a security is rated by an NRSRO, the more credit risk it is
considered to represent.
    
     Other Risks. Certain investment strategies employed by the Fund may involve
additional investment risk. Liquidity risk involves certain securities which may
be difficult or impossible to sell at the time and the price that the Fund would
like.      

     Municipal Obligations.  Opinions relating to the validity of Municipal
Obligations and to the exemption of interest thereon from federal income tax are
rendered by bond counsel to the respective issuers at the time of issuance, and
opinions relating to the validity of and the tax-exempt status of payments
received by the Fund for tax-exempt derivative securities are rendered by
counsel to the respective sponsors of such securities.  The Adviser will rely on
such opinions and will not review independently the underlying proceedings
relating to the issuance of Municipal Obligations, the creation of any tax-
exempt derivative securities, or the bases for such opinions.

     Year 2000.  Like other mutual funds, financial and business organizations
and individuals around the world, the Fund could be adversely affected if the
computer systems used by the Adviser and the Fund's other service providers, or
persons with whom they deal, do not properly process and calculate date-related
information and data from and after January 1, 2000.  This possibility is
commonly known as the "Year 2000 Problem."  The Fund has been advised by the
Adviser, the Administrators and the Custodian that they are actively taking
steps to address the Year 2000 Problem with respect to the computer systems that
they use and to obtain assurances that comparable steps are being taken by the
Fund's other major service providers.  While there can be no assurance that the
Fund's service providers will be Year 2000 compliant, the Fund's service
providers expect that their plans to be compliant will be achieved.

                             MANAGEMENT OF THE FUND

INVESTMENT ADVISER
    
     The Adviser, a wholly-owned indirect subsidiary of PNC Bank, serves as the
Fund's investment adviser.  The Adviser and its affiliates are one of the
largest U.S. bank managers of mutual funds, with assets currently under
management in excess of $46 billion.  BIMC (formerly known as PNC Institutional
Management Corporation or "PIMC") was organized in 1977 by PNC Bank to perform
advisory services for investment companies and has its principal offices at
Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, Delaware
19809.      
    
     As investment adviser, BIMC manages the Fund and is responsible for all
purchases and sales of the Fund's securities. For the investment advisory
services provided and expenses assumed by it, BIMC is entitled to receive a fee,
computed daily and payable monthly, based on the Fund's average net assets. BIMC
and PFPC, the co-administrator, may from time to time reduce the investment
advisory and administration fees otherwise payable to them or may reimburse the
Fund for its operating expenses. Any fees waived and any expenses reimbursed by
BIMC and PFPC with respect to a particular fiscal year are not recoverable. For
the fiscal year ended September 30, 1998, the Fund paid investment advisory fees
and administration fees each aggregating .07% (net of waivers) of its average
net assets. The services provided by BIMC and the fees payable by the Fund for
these services are described further in the Statement of Additional Information
under "Management of the Funds."      

                            SHAREHOLDER INFORMATION

PRICE OF FUND SHARES

     The Fund's net asset value per share for purposes of pricing purchase and
redemption orders is determined by PFPC Inc. ("PFPC"), the Funds co-
administrator, as of 12:00 noon and 4:00 P.M., Eastern time, on each day on
which both the New York Stock Exchange and the Federal Reserve Bank of
Philadelphia are open for business (a "Business Day"). The net asset value per
share of each class of the Fund's shares is calculated by adding the value of
all securities and other assets of the Fund that are allocable to a particular
class, subtracting liabilities charged to such class, and dividing the result by
the total number of outstanding shares of such class.  In computing net asset
value, the Fund uses the amortized cost method of valuation as described in the
Statement of Additional Information under "Additional Purchase and Redemption
Information."  Under the 1940 Act, the Fund may postpone the date of payment of
any redeemable security for up to seven days.

                                      -9-
<PAGE>
 
PURCHASE OF SHARES
    
     Fund shares are sold at the net asset value per share next determined after
confirmation of a purchase order by PFPC, which also serves as the Fund's
transfer agent. Purchase orders for shares are accepted only on Business Days
and must be transmitted to PFPC in Wilmington, Delaware by telephone (800-441-
7450; in Delaware: 302-791-5350) or through the Fund's computer access program.
Orders accepted before 12:00 noon, Eastern time, for which payment has been
received by PNC Bank, N.A. ("PNC Bank"), the Fund's custodian, will be executed
at 12:00 noon. Orders accepted after 12:00 noon and before 2:30 P.M., Eastern
time (or orders accepted earlier in the same day for which payment has not been
received by 12:00 noon), will be executed at 4:00 P.M., Eastern time, if payment
has been received by PNC Bank by that time. Orders received at other times, and
orders for which payment has not been received by 4:00 P.M., Eastern time, will
not be accepted, and notice thereof will be given to the institution placing the
order. (Payment for orders which are not received or accepted will be returned
after prompt inquiry to the sending institution.) The Fund may in its discretion
reject any order for shares.      

     Payment for Fund shares may be made only in federal funds or other funds
immediately available to PNC Bank.  The minimum initial investment by an
institution is $3 million for MuniCash Shares and $5,000 for MuniCash Dollar
Shares; however, broker-dealers and other institutional investors may set a
higher minimum for their customers.  There is no minimum subsequent investment.
The Fund, at its discretion, may reduce the minimum initial investment for
MuniCash Shares for specific institutions whose aggregate relationship with the
Provident Institutional Funds is substantially equivalent to this $3 million
minimum and warrants this reduction.

     Fund shares are sold and redeemed without charge by the Fund.
Institutional investors purchasing or holding Fund shares for their customer
accounts may charge customer fees for cash management and other services
provided in connection with their accounts.  A customer should, therefore,
consider the terms of its account with an institution before purchasing Fund
shares.  An institution purchasing or redeeming Fund shares on behalf of its
customers is responsible for transmitting orders to the Fund in accordance with
its customer agreements.

     Conflict of interest restrictions may apply to an institution's receipt of
compensation paid by the Fund in connection with the investment of fiduciary
funds in MuniCash Dollar Shares.  (See also "Management of the Fund -- Service
Organizations," as described in the Statement of Additional Information.)
Institutions, including banks regulated by the Comptroller of the Currency and
investment advisers and other money managers subject to the jurisdiction of the
SEC, the Department of Labor or state securities commissions, are urged to
consult their legal advisors before investing fiduciary funds in MuniCash Dollar
Shares.  (See also "Management of the Fund -- Banking Laws," as described in the
Statement of Additional Information).

REDEMPTION OF SHARES

     Redemption orders must be transmitted to PFPC in Wilmington, Delaware in
the manner described under "Purchase of Shares."  Shares are redeemed at the net
asset value per share next determined after PFPC's receipt of the redemption
order.  While the Fund intends to use its best efforts to maintain its net asset
value per share at $1.00, the proceeds paid to a shareholder upon redemption may
be more or less than the amount invested depending upon a share's net asset
value at the time of redemption.  Call 1-800-441-7450 (in Delaware: 302-791-
5350) to place redemption orders.

     Payment for redeemed shares for which a redemption order is received by
PFPC before 12:00 noon, Eastern time, on a Business Day is normally made in
federal funds wired to the redeeming shareholder on the same day.  Payment for
redemption orders which are received between 12:00 noon and 4:00 P.M., Eastern
time, or on a day when PNC Bank is closed, is normally wired in federal funds on
the next day following redemption that PNC Bank is open for business.

     The Fund shall have the right to redeem shares in any account if the value
of the account is less than $1,000 after sixty-days' prior written notice to the
shareholder.  Any such redemption shall be effected at the net asset value next
determined after the redemption order is entered.  If during the sixty-day
period the shareholder increases the value of its account to $1,000 or more, no
such redemption shall take place.  Moreover, if a shareholder's MuniCash Shares
account falls below an average of $100,000 in any particular calendar month, the
account may be charged an account maintenance fee with respect to that month.
In addition, the Fund may also redeem shares involuntarily under certain special
circumstances described in the Statement of Additional Information under
"Additional Purchase and Redemption Information."

SHAREHOLDER SERVICE PLAN

     Institutional investors, such as banks, savings and loan associations and
other financial institutions, including affiliates of PNC Bank Corp.  ("Service
Organizations"), may purchase Dollar Shares.  MuniCash Dollar Shares are
identical in all respects to MuniCash Shares except that they bear the service
fees described below and enjoy certain exclusive voting rights on matters
relating to these fees.  The Fund will enter into an agreement with each Service
Organization which purchases Dollar Shares requiring it to provide support
services to its customers who are the beneficial owners of such shares in
consideration of the Fund's payment of .25% (on an annualized basis) of the
average daily net asset value of the Dollar Shares held by the Service
Organization for the benefit of customers.  Such services, which are described
more fully in the Statement of Additional Information under "Management of the
Fund - Service Organizations," include aggregating and processing purchase and
redemption requests from customers and placing net purchase and redemption
orders with PFPC; processing dividend payments from the Fund on behalf of
customers; providing information periodically to customers showing their
positions in Dollar Shares; and providing sub-accounting or the information
necessary for sub-accounting with respect to Dollar Shares beneficially owned by
customers.  Under the terms of the agreements, Service Organizations are
required to provide to their customers a schedule of any fees that they may
charge customers in connection with their investments in Dollar Shares.
MuniCash Shares are sold to institutions that have not entered into servicing
agreements with the Fund in connection with their investments.

DIVIDENDS, CAPITAL GAINS AND DISTRIBUTIONS AND TAXES


     The Fund declares dividends daily and distributes substantially all of its
net investment income to shareholders monthly.  Shares begin accruing dividends
on the day the purchase order for the shares is effected and continue to accrue
dividends through the day before such shares are redeemed.  Dividends are paid
monthly by check, or by wire transfer if requested in writing by the
shareholder, within five business days after the end of the month or within five
business days after a redemption of all of a shareholder's shares of a
particular class.

     Dividends are determined in the same manner for each class of shares of the
Fund.  MuniCash Dollar Shares bear all the expense of fees paid to Service
Organizations, and as a result, at any given time, the dividend on MuniCash
Dollar Shares will be approximately .25% lower than the dividend on MuniCash
Shares.

     Institutional shareholders may elect to have their dividends reinvested in
additional full and fractional shares of the same class of shares with respect
to which such dividends are declared at the net asset value of such shares on
the payment date.  Reinvested dividends receive the same tax treatment as
dividends paid in cash.  Reinvestment elections, and any revocations thereof,
must be made in writing to PFPC, the Fund's transfer agent, at P.O. Box 8950,
Wilmington, Delaware 19885-9628 and will become effective after its receipt by
PFPC with respect to dividends paid.

TAXES
    
     The Fund's distributions will generally constitute tax-exempt income for 
shareholders for federal income tax purposes.  It is possible, depending upon 
the Fund's investments, that a portion of the Fund's distributions could be 
taxable to shareholders as ordinary income or capital gains, but the Fund does 
not expect that this will be the case.  Moreover, although the distributions are
exempt for federal income tax purposes, they will generally constitute taxable 
income for state and local income tax purposes except that, subject to 
limitations that vary depending on the state, distributions from interest paid 
by a state or municipal entity may be exempt from tax in that state.       
    
     Interest on indebtedness incurred by a shareholder to purchase or carry 
shares of the Fund generally will not be deductible for federal income tax 
purposes.       
    
     You should note that a portion of the exempt-interest dividends paid by 
the Fund may constitute an item of tax preference for purposes of determining
federal alternative minimum tax liability. Exempt-interest dividends will also
be considered along with other adjusted gross income in determining whether any
Social Security or railroad retirement payments received by you are subject to
federal income taxes.       
    
     PFPC, as transfer agent, will send each Fund shareholder or its authorized 
representative an annual statement designating the amount, if any, of any 
dividends and distributions made during each year and their federal tax 
treatment.       
    
     Dividends declared in December of any year, and payable to shareholders of 
record on a specified date in December, will be deemed to have been received by 
the shareholders and paid by the Fund on December 31 of such year in the event 
such dividends are actually paid during January of the following year.       
    
     You should also consult your tax adviser for further information regarding 
the federal, state and local tax consequences with respect to your specific 
situation.

                             FINANCIAL HIGHLIGHTS
    
     The financial highlights tables are intended to help you understand the
Fund's financial performance for the past 5 years. Certain information reflects
financial results for a single Fund share. The total returns in the table
represent the rate that an investor would have earned or lost on an investment
in the Fund (assuming reinvestment of all dividends and distributions). This
information has been audited by KPMG LLP, whose report, along with the Fund's
financial statements, are incorporated by reference into the Statement of
Additional Information and included in the Annual Report, each of which is
available upon request.

                              possible, from California State personal income
                              tax as is consistent with the preservation of
                              capital and relative stability of principal.      
    
INVESTMENT POLICIES:          The Fund invests primarily in debt obligations
                              issued by or on behalf of the State of California
                              and other states, territories, and possessions of
                              the United States, the District of Columbia, and
                              their respective authorities, agencies,
                              instrumentalities and political subdivisions, and
                              tax-exempt derivative securities such as tender
                              option bonds, participations, beneficial interests
                              in trusts and partnership interests ("Municipal
                              Obligations"). Dividends paid by the Fund that are
                              derived from interest on obligations that is
                              exempt from taxation under the Constitution or
                              statutes of California ("California Municipal
                              Obligations") are exempt from regular federal,
                              California State personal income tax. California
                              Municipal Obligations include municipal securities
                              issued by the State of California and its
                              political sub-divisions, as well as certain other
                              governmental issuers such as the Commonwealth of
                              Puerto Rico.      

    
PRINCIPAL RISKS OF INVESTING: Although the Fund invests in money market
                              instruments which the investment adviser,
                              BlackRock Institutional Management Corporation
                              ("BIMC," or the "Adviser") believes present
                              minimal credit risks at the time of purchase,
                              there is a risk that an issuer may not be able to
                              make principal and interest payments when due.
                              While the Fund seeks to maintain a constant net 
                              asset value of $1.00 per share, the Fund is also
                              subject to risks related to changes in prevailing
                              interest rates, since generally, a fixed-income
                              security will increase in value when interest
                              rates fall and decrease in value when interest
                              rates rise.      
<PAGE>
 
                              Because the Fund concentrates its investments in
                              California Municipal Obligations, it is classified
                              as non-diversified.  This means that it may invest
                              a greater percentage of its assets in a particular
                              issuer, and that its performance will be dependent
                              upon a smaller category of securities than a
                              diversified portfolio.  Accordingly, the Fund may
                              experience greater fluctuations in net asset value
                              and may have greater risk of loss.

                              Dividends derived from interest on Municipal
                              Obligations other than California Municipal
                              Obligations are exempt from federal income tax but
                              may be subject to California State personal income
                              tax.

                              An investment in the Fund is not a deposit in  PNC
                              Bank, N.A. and is not insured or guaranteed by the
                              Federal Deposit Insurance Corporation or any other
                              government agency.  Although the Fund seeks to
                              preserve the value of your investment at $1.00 per
                              share, it is possible to lose money by investing
                              in the Fund.

     Operating Expenses for Administration Shares, Plus Shares, Cash Reserve

     from time to time waive the investment advisory and administration fees
     otherwise payable to them or may reimburse the Fund for its operating
     expenses. The Adviser and PFPC expect to continue such fee waivers.

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods.  The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same.  Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                   INVESTMENT STRATEGIES AND RISK DISCLOSURE
                                        
     The Fund is a money market fund.  The investment objective of the Fund is
to provide investors with as high a level of current interest income that is
exempt from federal income tax and, to the extent possible, from California
State personal income tax as is consistent with the preservation of capital and
relative stability of principal.  The Fund's investment objective may be changed
by the Board of Trustees without shareholder approval.  The Fund invests
primarily in California Municipal Obligations.

     Substantially all of the Fund's assets are invested in Municipal
Obligations.  The Fund expects that, except during temporary defensive periods
or when acceptable securities are unavailable for investment by the Fund, the
Fund's assets will be invested primarily in California Municipal Obligations.
At least 50% of the Fund's assets must be invested in obligations which, when
held by an individual, the interest therefrom is exempt from California personal
income taxation (i.e., California Municipal Obligations and certain U.S.
Government obligations) at the close of each quarter of its taxable year so as
to permit the Fund to pay dividends that are exempt from California State
personal income tax.  Dividends, regardless of their source, may be subject to
local taxes.  The Fund will not knowingly purchase securities the interest on
which is subject to federal income tax; however, the Fund may hold uninvested
cash reserves pending investment during temporary defensive periods or, if in
the opinion of the Adviser, suitable tax-exempt obligations are unavailable.
Uninvested cash reserves will not earn income.
    
     The Fund invests in Municipal Obligations which are determined by the
Adviser to present minimal credit risk pursuant to guidelines approved by the
Board of Trustees of Provident Institutional Funds pursuant to Rule 2a-7 under
the Investment Company Act of 1940, as amended, and other rules of the
Securities and Exchange Commission. Pursuant to Rule 2a-7, the Fund is
authorized to purchase instruments that are determined to have minimum credit
risk and are Eligible Securities. Applicable Eligible Securities are:       
         
     .    instruments which are rated at the time of purchase (or which are
          guaranteed or in some cases otherwise supported by guarantees or other
          credit supports with such ratings) in one of the top two rating
          categories by two unaffiliated nationally recognized statistical
          rating organizations ("NRSRO") (or one NRSRO if the security or
          guarantee was rated by only one NRSRO);       
         
     .    instruments issued or guaranteed by persons with short-term debt 
          having such ratings;       
         
     .    unrated instruments determined by the Adviser, pursuant to procedures
          approved by the Board of Trustees, to be of comparable quality to such
          instruments; and       
         
     .    shares of other open-end investment companies that invest in the type 
          of obligations in which the Fund may invest.       

                                      -7-
<PAGE>
     
     INVESTMENTS.  The Fund's investments may include the following:       
    
     Municipal Obligations.  The Fund may purchase Municipal Obligations which
are classified as "general obligation" securities and "revenue" securities.
Revenue securities may include private activity bonds which are not payable from
the unrestricted revenues of the issuer.  Consequently, the credit quality of 
private activity bonds is usually directly related to the credit standing of the
corporate user of the facility involved.  While interest paid on private 
activity bonds will be exempt from regular federal income tax, it may be treated
as a specific tax preference item under the federal alternative minimum tax. The
portfolio may also include "moral obligation" securities.     
    
     Variable and Floating Rate Instruments.  The Fund may purchase variable or
floating rate notes issued by industrial development authorities and other
governmental entities, which are instruments that provide for adjustments in the
interest rate on certain reset dates or whenever a specified interest rate index
changes, respectively.       

     When-Issued and Delayed Settlement Transactions.  The Fund may purchase
securities on a "when-issued" or "delayed settlement" basis.  The Fund expects
that commitments to purchase when-issued or delayed settlement securities will
not exceed 25% of the value of its total assets absent unusual market conditions
and that commitments by the Fund to purchase when-issued securities will not
exceed 45 days.  The Fund does not intend to purchase when-issued or delayed
settlement securities for speculative purposes but only in furtherance of its
investment objective.

     Stand-by Commitments.  The Fund may acquire "stand-by commitments" with
respect to Municipal Obligations held in its portfolio.  The Fund will acquire
stand-by commitments solely to facilitate portfolio liquidity and does not
intend to exercise its rights thereunder for trading purposes.
    
     Investment Company Securities.  The Fund may invest in securities issued by
other open-end investment companies that invest in the type of obligations in
which the Fund may invest and that determine their net asset value per share
based upon the amortized cost or penny rounding method.  Investments in the 
securities of other investment companies will cause the Fund (and, indirectly 
the Fund's shareholders) to bear proportionately the costs incurred in
connection with the other investment companies' operations.       
    
     Illiquid Securities.  The Fund will not invest more than 10% of the value
of its total assets in illiquid securities, which may be illiquid due to legal
or contractual restrictions on resale or the absence of readily available market
quotations. Securities that have readily available market quotations are not
deemed illiquid for purposes of this limitation.       

     Other Types of Investments.  This Prospectus describes the Fund's
principal investment strategies, and the particular types of securities in which
the Fund principally invests.  The Fund may, from time to time, make other types
of investments and pursue other investment strategies in support of its overall
investment goal.  These supplemental investment strategies are described in
detail in the Statement of Additional Information, which is referred to on the
back cover of this Prospectus.

     RISK FACTORS.  The principal risks of investing in the Fund are also
described above in the Risk/Return Summary. The following supplements that
description.

                                      -8-
<PAGE>
 
     Interest Rate Risk.  Generally, a fixed-income security will increase in
value when interest rates fall and decrease in value when interest rates rise.
As a result, if interest rates were to change rapidly, there is a risk that the
change in market value of the Fund's assets may not enable the Fund to maintain
a stable net asset value of $1.00 per share.

     Credit Risk.  The risk that an issuer will be unable to make principal and
interest payments when due is known as "credit risk."  U.S. government
securities are generally considered to be the safest type of investment in terms
of credit risk.  Municipal obligations generally rank between U.S. government
securities and corporate debt securities in terms of credit safety.  Credit
quality ratings published by a NRSRO are widely accepted measures of credit
risk.  The lower a security is rated by a NRSRO the more credit risk it is
considered to represent.
    
     Other Risks.  Certain investment strategies employed by the Fund may 
involve additional investment risk. Liquidity risk involves certain securities
which may be difficult or impossible to sell at the time and the price that the
Fund would like.     

     Municipal Obligations.  Opinions relating to the validity of Municipal
Obligations and to the exemption of interest thereon from federal income tax are
rendered by bond counsel to the respective issuers at the time of issuance, and
opinions relating to the validity of and the tax-exempt status of payments
received by the Fund for tax-exempt derivative securities are rendered by
counsel to the respective sponsors of such securities. The Adviser will rely on
such opinions and will not review independently the underlying proceedings
relating to the issuance of Municipal Obligations, the creation of any tax-
exempt derivative securities, or the bases for such opinions.

     Special Considerations Affecting the Fund.  The Fund is concentrated in
securities issued by the State of California or entities within the State of
California and therefore, investment in the Fund may be riskier than an
investment in other types of money market funds.  The Fund's ability to achieve
its investment objective is dependent upon the ability of the issuers of
California Municipal Obligations to timely meet their continuing obligations
with respects to the Municipal Obligations.  Any reduction in the
creditworthiness of issuers of California Municipal Obligations could adversely
affect the market values and marketability of California Municipal Obligations,
and, consequently, the net asset value of the Fund's portfolio.

     General obligation bonds of the state of California are currently rated A+
and A1, respectively, by Standard & Poor's Ratings Services and Moody's
Investors Service, Inc.

     Certain California constitutional amendments, legislative measures,
executive orders, administrative regulations and voter initiatives could result
in certain adverse consequences affecting California Municipal Obligations.
Significant financial and other considerations relating to the Fund's
investments in California Municipal Obligations are summarized in the Statement
of Additional Information.

     The Fund may invest more than 25% of its assets in Municipal Obligations
the interest on which is paid solely from revenues of similar projects if such
investment is deemed necessary or appropriate by the Fund's Adviser.  To the
extent that the Fund's assets are concentrated in Municipal Obligations payable
from revenues on similar projects, the Fund will be subject to the 

                                      -9-
<PAGE>
 
peculiar risks presented by such projects to a greater extent than it would be
if the Fund's assets were not so concentrated.

     Year 2000.  Like other mutual funds, financial and business organizations
and individuals around the world, the Fund could be adversely affected if the
computer systems used by the Adviser and the Fund's other service providers, or
persons with whom they deal, do not properly process and calculate date-related
information and data from and after January 1, 2000.  This possibility is
commonly known as the "Year 2000 Problem."  The Fund has been advised by the
Adviser, the Administrators and the Custodian that they are taking steps to
address the year 2000 Problem with respect to the computer systems that they use
and to obtain assurances that comparable steps are being taken by the Fund's
other service providers.  While there can be no assurance that the Fund's
service providers will be Year 2000 compliant, the Fund's service providers
expect that their plan to be compliant will be achieved.

                            MANAGEMENT OF THE FUND

INVESTMENT ADVISER
    
     The Adviser, a wholly-owned indirect subsidiary of PNC Bank, serves as the
Fund's investment adviser.  The Adviser and its affiliates are one of the
largest U.S. bank managers of mutual funds, with assets currently under
management in excess of $46 billion.  BIMC (formerly known as PNC Institutional
Management Corporation or "PIMC") was organized in 1977 by PNC Bank to perform
advisory services for investment companies and has its principal offices at
Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, Delaware
19809.      
    
     As investment adviser, BIMC manages the Fund and is responsible for all
purchases and sales of the Fund's securities. For the investment advisory
services provided and expenses assumed by it, BIMC is entitled to receive a fee,
computed daily and payable monthly, based on the Fund's average net assets. BIMC
and PFPC, the co-administrator, may from time to time reduce the investment
advisory and administration fees otherwise payable to them or may reimburse the
Fund for its operating expenses. Any fees waived and any expenses reimbursed by
BIMC and PFPC with respect to a particular fiscal year are not recoverable. For
the fiscal year ended January 31, 1998, the Fund paid investment advisory fees
and administration fees each aggregating .07% (net of waivers) of its average
net assets. The services provided by BIMC and the fees payable by the Fund for
these services are described further in the Statement of Additional Information
under "Management of the Funds."      


                            SHAREHOLDER INFORMATION

PRICE OF FUND SHARES

     The Fund's net asset value per share for purposes of pricing purchase and
redemption orders is determined by BIMC, the Funds adviser, as of 12:00 noon and
4:00 P.M., Eastern time, (9:00 A.M. and 1:00 P.M., Pacific Time) on each day on
which both the California Stock 

                                      -10-
<PAGE>
 
Exchange and the Federal Reserve Bank of Philadelphia are open for business (a
"Business Day"). The net asset value per share of each class of the Fund's
shares is calculated by adding the value of all securities and other assets of
the Fund that are allocable to a particular class, subtracting liabilities
charged to such class, and dividing the result by the total number of
outstanding shares of such class. In computing net asset value, the Fund uses
the amortized cost method of valuation as described in the Statement of
Additional Information under "Additional Purchase and Redemption Information."
Under the 1940 Act, the Fund may postpone the date of payment of any redeemable
security for up to seven days.

PURCHASE OF SHARES
    
     Fund shares are sold at the net asset value per share next determined after
confirmation of a purchase order by PFPC, which also serves as the Fund's
transfer agent. Purchase orders for shares are accepted only on Business Days
and must be transmitted to PFPC in Wilmington, Delaware by telephone (800-441-
7450; in Delaware: 302-791-5350) or through the Fund's computer access program.
Orders accepted by 12:00 noon, Eastern time (9:00 A.M., Pacific Time), for which
payment has been received by PNC Bank, N.A. ("PNC Bank"), the Fund's custodian
by 4:00 P.M., Eastern Time (1:00 P.M., Pacific Time), will be executed the same
day. Orders received after 12:00 noon Eastern Time (9:00 A.M., Pacific Time) and
orders for which payment has not been received by 4:00 P.M. Eastern Time (1:00
P.M., Pacific Time), will not be accepted, and notice thereof will be given to
the institution placing the order. (Payment for orders which are not received or
accepted will be returned after prompt inquiry to the sending institution.) 
     

     Payment for Fund shares may be made only in federal funds or other funds
immediately available to PNC Bank.  The minimum initial investment by an
institution is $5,000; however, broker-dealers and other institutional investors
may set a higher minimum for their customers.  There is no minimum subsequent
investment.  The Fund, at its discretion, may limit or reject any order for
shares.

     Fund shares are sold and redeemed without charge by the Fund.
Institutional investors purchasing or holding Fund shares for their customer
accounts may charge customer fees for cash management and other services
provided in connection with their accounts.  A customer should, therefore,
consider the terms of its account with an institution before purchasing Fund
shares.  An institution purchasing or redeeming Fund shares on behalf of its
customers is responsible for transmitting orders to the Fund in accordance with
its customer agreements.

     Conflict of interest restrictions may apply to an institution's receipt of
compensation paid by the Fund in connection with the investment of fiduciary
funds in Administration Shares, Dollar Shares, Plus Shares, Cash Reserve Shares 
or Cash Management Shares.  (See also "Management of the Fund -- Service
Organizations," as described in the Statement of Additional Information.)
Institutions, including banks regulated by the Comptroller of the Currency and
investment advisers and other money managers subject to the jurisdiction of the
SEC, the Department of Labor or state securities commissions, are urged to
consult their legal advisors before investing fiduciary funds in Administration 
Shares, Dollar Shares, Plus Shares, Cash Reserve Shares or Cash Management
Shares. (See also

                                      -11-
<PAGE>
 
"Management of the Fund -- Banking Laws," as described in the Statement of
Additional Information).

REDEMPTION OF SHARES

     Redemption orders must be transmitted to PFPC in Wilmington, Delaware in
the manner described under "Purchase of Shares."  Shares are redeemed at the net
asset value per share next determined after PFPC's receipt of the redemption
order.  While the Fund intends to use its best efforts to maintain its net asset
value per share at $1.00, the proceeds paid to a shareholder upon redemption may
be more or less than the amount invested depending upon a share's net asset
value at the time of redemption.  (Call 1-800-441-7450 (in Delaware: 302-791-
5350) to place redemption orders).

     Payment for redeemed shares for which a redemption order is accepted by
PFPC prior to Noon, Eastern time (9:00 A.M., Pacific Time), on a Business Day is
normally made in federal funds wired to the redeeming shareholder on the same
day.  Payment for redemption orders which are received after Noon, Eastern time
or on a day when PNC Bank is closed, is normally wired in federal funds on the
next day following redemption that PNC Bank is open for business.

     The Fund shall have the right to redeem shares in any Fund account if the
value of the account is less than $500, after sixty-days' prior written notice
to the shareholder.  Any such redemption shall be effected at the net asset
value next determined after the redemption order is entered.  If during the
sixty-day period the shareholder increases the value of its Fund account to $500
or more, no such redemption shall take place.  In addition, the Fund may also
redeem shares involuntarily under certain special circumstances described in the
Statement of Additional Information under "Additional Purchase and Redemption
Information."

DISTRIBUTION AND SHAREHOLDER SERVICE PLANS

     The Fund offers six classes of shares. The difference between the classes 
of shares is the fees borne by a class of shares pursuant to separate fee plans 
adopted by each class. California Money Fund Shares do not bear any fees for 
distribution, servicing, shareholder servicing, sweep fees or cash sweep 
marketing services. The fees borne by the other classes are as follows:

Shares are sold to institutional investors such as banks, saving and loan
associations, and other financial institutions, including affiliates of PNC Bank
Corp. ("Service Organizations"). Plus Shares are sold to broker-dealers. Because
fees associated with the distribution and/or shareholder service plans are paid
out of the Fund's assets on an ongoing basis, over time holders of the share
classes described above may pay more than the economic equivalent of the maximum
front-end sales charge permitted by NASD Regulation, Inc.

Plus Shares may be requested to provide from time to time assistance (such as
the forwarding of sales literature and advertising to their customers) in
connection with the distribution of Plus Shares.  Under the terms of the
agreements, Service Organizations are required to provide to their customers a
schedule of any fees that they may charge customers in connection with their
investments in Dollar or Plus Shares.  Money Shares are sold to institutions
that have not entered into servicing agreements with the Fund in connection with
their investments.

DIVIDENDS AND DISTRIBUTIONS

     The Fund declares dividends daily and distributes substantially all of its
net investment income to shareholders monthly.  Shares begin accruing dividends
on the day the purchase order for the shares is effected and continue to accrue
dividends through the day before such shares are redeemed.  Dividends are paid
monthly by check, or by wire transfer if requested in writing by the
shareholder, within five business days after the end of the month or within five
business days after a redemption of all of a shareholder's shares of a
particular class.

     Dividends are determined in the same manner for each class of shares of the
Fund.  Dollar and Plus Shares bear all the expense of fees paid to Service
Organizations, and as a result, at any given time, the dividend on Dollar or
Plus Shares will be approximately .25% lower than the dividend on Money Shares.

     Institutional shareholders may elect to have their dividends reinvested in
additional full and fractional shares of the same class of shares with respect
to which such dividends are declared at the net asset value of such shares on
the payment date.  Reinvested dividends receive the same tax treatment as
dividends paid in cash.  Reinvestment elections, and any revocations thereof,
must be made in writing to PFPC, the Fund's transfer agent, at P.O. Box 8950,
Wilmington, Delaware 19885-9628 and will become effective after its receipt by
PFPC with respect to dividends paid.

TAXES
    
     The Fund's distributions will generally constitute tax-exempt income for 
shareholders for federal income tax purposes. It is possible, depending upon the
Fund's investments, that a portion of the Fund's distributions could be taxable 
to shareholders as ordinary income or capital gains, but the Fund does not 
expect that this will be the case.      
    
     Interest on indebtedness incurred by a shareholder to purchase or carry 
shares of the Fund generally will not be deductible for federal income tax 
purposes.      
    
     You should note that a portion of the exempt-interest dividends paid by the
Fund may constitute an item of tax preference for purposes of determining 
federal alternative minimum tax liability. Exempt-interest dividends will also 
be considered along with other adjusted gross income in determining whether any 
Social Security or railroad retirement payments received by you are subject to 
federal income taxes.      
    
     Dividends that are paid by the Fund to non-corporate shareholders and are 
derived from interest on California Municipal Obligations or certain U.S. 
Government obligations are also exempt from California state personal income 
tax. However, dividends paid to corporate shareholders subject to California 
state franchise tax or California state corporate income tax will be taxed as 
ordinary income to such shareholders, notwithstanding that all or a portion of 
such dividends is exempt from California state personal income tax. Moreover, to
the extent that the Fund's dividends are derived from interest on debt 
obligations other than California Municipal Obligations or certain U.S. 
Government obligations such dividends will be subject to California state 
personal income tax, even though such dividends may be exempt for Federal income
tax purposes.     
    
     Dividends derived from U.S. Government obligations generally will be 
exempt from state and local tax as well. However, except as noted with respect 
to California state personal income tax, in some situations distributions of net
investment income may be taxable to investors under state or local law as 
dividend income even though all or a portion of such distributions may be 
derived from interest on tax-exempt obligations which, if realized directly, 
would be exempt from such income taxes.      
    
     PFPC, as transfer agent, will send each Fund shareholder or its authorized 
representative an annual statement designating the amount, if any, of any 
dividends and distributions made during each year and their federal and 
California tax treatment.      
    
     Dividends declared in the last quarter of any year, and payable to 
shareholders of record on a specified date in December, will be deemed to have 
been received by the shareholders and paid by the Fund on December 31 of such 
year in the event such dividends are actually paid during January of the 
following year.      
    
     You should also consult your tax adviser for further information regarding 
the federal, state and local tax consequences with respect to your specific 
situation.

                             FINANCIAL HIGHLIGHTS
                                            
     The financial highlights tables are intended to help you understand the
Fund's financial performance for the past 5 years.  Certain information reflects
financial results for a single Fund share.  The total returns in the table
represent the rate that an investor would have earned or lost on an investment
in the Fund (assuming reinvestment of all dividends and distributions).  This
information, except for the 6 month period ended July 31, 1998, has been audited
by PricewaterhouseCoopers LLP, whose report, along with the Fund's financial
statements, are incorporated by reference into the Statement of Additional
Information and included in the Annual Report, each of which is available upon
request. No Plus Shares were issued or outstanding during the periods covered by
these financial highlights. Administration Shares, Cash Reserve Shares and Cash
Management Shares have not yet commenced operations, therefore no financial
information has been provided for these classes.

                              RISK/RETURN SUMMARY
                                            
INVESTMENT GOAL:                  The Fund seeks to provide investors with as
                                  high a level of current interest income that
                                  is exempt from federal income tax and, to the
                                  extent possible, from New York State and New
                                  York City personal income taxes as is
                                  consistent with the preservation of capital
                                  and relative stability of principal.      
    
INVESTMENT POLICIES:              The Fund invests primarily in debt obligations
                                  issued by or on behalf of the State of New
                                  York. We may also invest in debt obligations
                                  issued by or on behalf of other states,
                                  territories, and possessions of the United
                                  States, the District of Columbia, and their
                                  respective authorities, agencies,
                                  instrumentalities and political subdivisions,
                                  and tax-exempt derivative securities such as
                                  tender option bonds, participations,
                                  beneficial interests in trusts and partnership
                                  interests ("Municipal Obligations"). Dividends
                                  paid by the Fund that are derived from
                                  interest on obligations that is exempt from
                                  taxation under the Constitution or statutes of
                                  New York ("New York Municipal Obligations")
                                  are exempt from regular federal, New York
                                  State and New York City personal income tax.
                                  New York Municipal Obligations include
                                  municipal securities issued by the State of
                                  New York and its political sub-divisions, as
                                  well as certain other governmental issuers
                                  such as the Commonwealth of Puerto Rico.      

    
PRINCIPAL RISKS OF INVESTING:     Although the Fund invests in money market
                                  instruments which the investment adviser,
                                  BlackRock Institutional Management Corporation
                                  ("BIMC," or the "Adviser") believes present
                                  minimal credit risks at the time of purchase,
                                  there is a risk that an issuer may not be able
                                  to make principal and interest payments when
                                  due. While the Fund seeks to maintain a
                                  constant net asset value of $1.00 per share,
                                  the Fund is also subject to risks related to
                                  changes in prevailing interest rates, since
                                  generally, a fixed-income security will
                                  increase in value when interest rates fall and
                                  decrease in value when interest rates rise.
     
<PAGE>
                                               
                                     
                                     Because the Fund concentrates its
                                     investments in New York Municipal
                                     Obligations, it is classified as non-
                                     diversified. This means that it may invest
                                     a greater percentage of its assets in a
                                     particular issuer, and that its performance
                                     will be dependent upon a smaller category
                                     of securities than a diversified portfolio.
                                     Accordingly, the Fund may experience
                                     greater fluctuations in net asset value and
                                     may have greater risk of loss.
                                         
                                     Dividends derived from interest on
                                     Municipal Obligations other than New York
                                     Municipal Obligations are exempt from
                                     federal income tax but may be subject to
                                     New York State and New York City personal
                                     income tax.      

                                     An investment in the Fund is not a deposit
                                     in PNC Bank, N.A. and is not insured or
                                     guaranteed by the Federal Deposit Insurance
                                     Corporation or any other government agency.
                                     Although the Fund seeks to preserve the
                                     value of your investment at $1.00 per
                                     share, it is possible to lose money by
                                     investing in the Fund.

WHO MAY WANT TO INVEST IN THE FUND:  The Fund is designed for institutional
                                     investors and their customers seeking as
                                     high a level of current interest income
                                     that is exempt from federal income tax and,
                                     to the extent possible, from New York State
                                     and New York City personal income taxes as
                                     is consistent with the preservation of
                                     capital and relative stability of
                                     principal. The Fund is particularly
                                     suitable for banks, corporations and other
                                     financial institutions that seek investment
                                     of short-term funds for their own accounts
                                     or for the accounts of their customers.

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods.  The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same.  Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                   INVESTMENT STRATEGIES AND RISK DISCLOSURE
                                        
     The Fund is a money market fund.  The investment objective of the Fund is
to provide investors with as high a level of current interest income that is
exempt from federal income tax and, to the extent possible, from New York State
and New York City personal income taxes as is consistent with the preservation
of capital and relative stability of principal.  The Fund's investment objective
may be changed by the Board of Trustees without shareholder approval.  The Fund
invests primarily in New York Municipal Obligations.
    
     Substantially all of the Fund's assets are invested in Municipal
Obligations.  The Fund expects that, except during temporary defensive periods
or when acceptable securities are unavailable for investment by the Fund, the
Fund's assets will be invested primarily in New York Municipal Obligations,
although the amount of the Fund's assets invested in such securities will vary
from time to time.  The Fund will not knowingly purchase securities the interest
on which is subject to regular federal income tax; however, the Fund may hold
uninvested cash reserves pending investment during temporary defensive periods
or, if in the opinion of the Adviser, suitable tax-exempt obligations are
unavailable. Uninvested cash reserves will not earn income.      
    
     The securities purchased by the Fund are subject to the quality,
diversification, and other requirements of Rule 2a-7 under the Investment
Company Act of 1940, as amended, and other rules of the Securities and Exchange
Commission.  The Fund will only purchase securities that present minimal credit
risk as determined by the Adviser pursuant to guidelines approved by the Board
of Trustees of Provident Institutional Funds.  Securities purchased by the Fund
(or the issuers of such securities) will be Eligible Securities. Applicable
Eligible Securities are:      
    
 .    instruments which are rated at the time of purchase (or which are 
     guaranteed or in some cases otherwise supported by guarantees or other
     credit supports with such ratings) in one of the top two rating categories
     by two unaffiliated nationally recognized statistical rating organizations
     ("NRSROs") (or one NRSRO if the security or guarantee was rated by only one
     NRSRO);      
    
 .    instruments issued or guaranteed by persons with short-term debt having 
     such ratings;      
    
 .    unrated instruments determined by the Adviser, pursuant to procedures 
     approved by the Board of Trustees, to be of comparable quality to such
     instruments; and      
    
 .    shares of other open-end investment companies that invest in the type of 
     obligation in which the Fund may invest.      
         

                                      -7-
<PAGE>
    
     INVESTMENTS.  The Fund's investments may include the following:       
    
     Municipal Obligations.  They may purchase Municipal Obligations which are
classified as "general obligation" securities and "revenue" securities.  Revenue
securities may include private activity bonds which are not payable from the
unrestricted revenues of the issuer.  Consequently, the credit quality of 
private activity bonds is usually directly related to the credit standing of the
corporate user of the facility involved. While interest paid on private activity
bonds will be exempt from regular federal income tax, it may be treated as a
specific tax preference item under the federal alternative minimum tax. The
portfolio may also include "moral obligation" securities.     
    
     Variable and Floating Rate Instruments.  The Fund may purchase variable or
floating rate notes issued by industrial development authorities and other
governmental entities, which are instruments that provide for adjustments in the
interest rate on certain reset dates or whenever a specified interest rate index
changes, respectively.     

     When-Issued and Delayed Settlement Transactions.  The Fund may purchase
securities on a "when-issued" or "delayed settlement" basis.  The Fund expects
that commitments to purchase when-issued or delayed settlement securities will
not exceed 25% of the value of its total assets absent unusual market conditions
and that commitments by the Fund to purchase when-issued securities will not
exceed 45 days.  The Fund does not intend to purchase when-issued or delayed
settlement securities for speculative purposes but only in furtherance of its
investment objective.

     Stand-by Commitments.  The Fund may acquire "stand-by commitments" with
respect to Municipal Obligations held in its portfolio.  The Fund will acquire
stand-by commitments solely to facilitate portfolio liquidity and does not
intend to exercise its rights thereunder for trading purposes.
    
     Investment Company Securities.  The Fund may invest in securities issued by
other open-end investment companies that invest in the type of obligations in
which the Fund may invest and that determine their net asset value per share
based upon the amortized cost or penny rounding method. Investments in the 
securities of other investment companies will cause the Fund (and, indirectly 
the Fund's shareholders) to bear proportionately the costs incurred in 
connection with the other investment companies' operations.       
    
     Illiquid Securities.  The Fund will not invest more than 10% of the value
of its total assets in illiquid securities, which may be illiquid due to legal
or contractual restrictions on resale or the absence of readily available market
quotations. Securities that have readily available market quotations are not
deemed illiquid for purposes of this limitation.       

     Other Types of Investments.  This Prospectus describes the Fund's
principal investment strategies, and the particular types of securities in which
the Fund principally invests.  The Fund may, from time to time, make other types
of investments and pursue other investment strategies in support of its overall
investment goal.  These supplemental investment strategies are described in
detail in the Statement of Additional Information, which is referred to on the
back cover of this Prospectus.

                                      -8-
<PAGE>
 
     RISK FACTORS. The principal risks of investing in the Fund are also
described above in the Risk/Return Summary. The following supplements that
description.

     Interest Rate Risk. Generally, a fixed-income security will increase in
value when interest rates fall and decrease in value when interest rates rise.
As a result, if interest rates were to change rapidly, there is a risk that the
change in market value of the Fund's assets may not enable the Fund to maintain
a stable net asset value of $1.00 per share.

     Credit Risk. The risk that an issuer will be unable to make principal and
interest payments when due is known as "credit risk." U.S. government securities
are generally considered to be the safest type of investment in terms of credit
risk. Municipal obligations generally rank between U.S. government securities
and corporate debt securities in terms of credit safety. Credit quality ratings
published by an NRSRO are widely accepted measures of credit risk. The lower a
security is rated by an NRSRO, the more credit risk it is considered to
represent.
    
     Other Risks. Certain investment strategies employed by the Fund may involve
additional investment risk. Liquidity risk involves certain securities which may
be difficult or impossible to sell at the time and the price that the Fund would
like.      
    
     Special Considerations Affecting the Fund.  The Fund's ability to achieve
its investment objective is dependent upon the ability of the issuers of New
York Municipal Obligations to meet their continuing obligations for the payment
of principal and interest.       

     Certain substantial issuers of New York Municipal Obligations (including
issuers whose obligations may be acquired by the Fund) have experienced serious
financial difficulties in recent years.  These difficulties have at times
jeopardized the credit standing and impaired the borrowings abilities of all New
York issuers and have generally contributed to higher interest costs for their
borrowing and fewer markets for their outstanding debt obligations. Although,
several different issues of municipal securities of New York State and its
agencies and instrumentalities and of New York City have been downgraded by
Standard & Poor's Ratings Services ("S&P") and Moody's Investors Service, Inc.
("Moody's"), in recent years, the most recent actions of S&P and Moody's have
been to place the debt obligations of New York State and New York City on Credit
Watch with positive implications and to upgrade the debt obligations of New York
City respectively.  Strong demand for New York Municipal Obligations has also at
times had the effect of permitting New York Municipal Obligations to be issued
with yields relatively lower, and after issuance, to trade in the market at
prices relatively higher, than comparably rated municipal obligations issued by
other jurisdictions.  A recurrence of the financial difficulties previously
experienced by certain issuers of New York Municipal Obligations could result in
defaults or declines in the market values of those issuers' existing obligations
and, possibly, in the obligations of other issuers of New York Municipal
Obligations.  Although as of the date of this Prospectus, no issuers of New York
Municipal Obligations are in default with respect to the payment of their
Municipal Obligations, the occurrence of any such default could affect adversely
the market values and marketability of all New York Municipal Obligations and,
consequently, the net asset value of the Fund's portfolio.

                                      -9-
<PAGE>
 
     Municipal Obligations.  Opinions relating to the validity of Municipal
Obligations and to the exemption of interest thereon from federal income tax
(and, with respect to New York Municipal Obligations, to the exemption of
interest thereon from New York State and New York City personal income taxes)
are rendered by bond counsel to the respective issuers at the time of issuance,
and opinions relating to the validity of and the tax-exempt status of payments
received by the Fund for tax-exempt derivative securities are rendered by
counsel to the respective sponsors of such securities.  The Adviser will rely on
such opinions and will not review independently the underlying proceedings
relating to the issuance of Municipal Obligations, the creation of any tax-
exempt derivative securities, or the bases for such opinions.

     Year 2000.  Like other mutual funds, financial and business organizations
and individuals around the world, the Fund could be adversely affected if the
computer systems used by the Adviser and the Fund's other service providers, or
persons with whom they deal, do not properly process and calculate date-related
information and data from and after January 1, 2000.  This possibility is
commonly known as the "Year 2000 Problem."  The Fund has been advised by the
Adviser, the Administrators and the Custodian that they are actively taking
steps to address the year 2000 Problem with respect to the computer systems that
they use and to obtain assurances that comparable steps are being taken by the
Fund's other service providers.  While there can be no assurance that the Fund's
service providers will by Year 2000 compliant, the Fund's service providers
expect that their plans to be compliant will be achieved.


                            MANAGEMENT OF THE FUND

INVESTMENT ADVISER
    
     The Adviser, a wholly-owned indirect subsidiary of PNC Bank, serves as the
Fund's investment adviser.  The Adviser and its affiliates are one of the
largest U.S. bank managers of mutual funds, with assets currently under
management in excess of $46 billion.  BIMC (formerly known as PNC Institutional
Management Corporation or "PIMC") was organized in 1977 by PNC Bank to perform
advisory services for investment companies and has its principal offices at
Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, Delaware
19809.       
    
     As investment adviser, BIMC manages the Fund and is responsible for all
purchases and sales of the Fund's securities. For the investment advisory
services provided and expenses assumed by it, BIMC is entitled to receive a fee,
computed daily and payable monthly, based on the Fund's average net assets. BIMC
and PFPC, the co-administrator, may from time to time reduce the investment
advisory and administration fees otherwise payable to them or may reimburse the
Fund for its operating expenses. Any fees waived and any expenses reimbursed by
BIMC and PFPC with respect to a particular fiscal year are not recoverable. For
the fiscal year ended July 31, 1998, the Fund paid investment advisory fees and 
administration fees each aggregating .06% (net of waivers) of its average net
assets. The services provided by BIMC and the fees payable by the Fund for these
services are described further in the Statement of Additional Information under
"Management of the Funds."       

                                      -10-
<PAGE>
 
PRICE OF FUND SHARES

     The Fund's net asset value per share for purposes of pricing purchase and
redemption orders is determined by BIMC, the Funds adviser, as of 12:00 noon and
4:00 P.M., Eastern time, on each day on which both the New York Stock Exchange
and the Federal Reserve Bank of Philadelphia are open for business (a "Business
Day"). The net asset value per share of each class of the Fund's shares is
calculated by adding the value of all securities and other assets of the Fund
that are allocable to a particular class, subtracting liabilities charged to
such class, and dividing the result by the total number of outstanding shares of
such class.  In computing net asset value, the Fund uses the amortized cost
method of valuation as described in the Statement of Additional Information
under "Additional Purchase and Redemption Information."  Under the 1940 Act, the
Fund may postpone the date of payment of any redeemable security for up to seven
days.


PURCHASE OF SHARES
    
     Fund shares are sold at the net asset value per share next determined after
confirmation of a purchase order by PFPC, which also serves as the Fund's
transfer agent. Purchase orders for shares are accepted only on Business Days
and must be transmitted to PFPC in Wilmington, Delaware by telephone (800-441-
7450; in Delaware: 302-791-5350) or through the Fund's computer access program.
Orders accepted by 12:00 noon, Eastern time, for which payment has been received
by PNC Bank, N.A. ("PNC Bank"), the Fund's custodian by 4:00 P.M., Eastern Time,
will be executed the same day. Orders received after 12:00 noon Eastern Time and
orders for which payment has not been received by 4:00 P.M. Eastern Time, will
not be accepted, and notice thereof will be given to the institution placing the
order. (Payment for orders which are not received or accepted will be returned
after prompt inquiry to the sending institution.)       

     Payment for Fund shares may be made only in federal funds or other funds
immediately available to PNC Bank.  The minimum initial investment by an
institution is $5,000; however, broker-dealers and other institutional investors
may set a higher minimum for their customers.  There is no minimum subsequent
investment.  The Fund, at its discretion, may limit or reject any order for
shares.

     Fund shares are sold and redeemed without charge by the Fund.
Institutional investors purchasing or holding Fund shares for their customer
accounts may charge customer fees for cash management and other services
provided in connection with their accounts.  A customer should, therefore,
consider the terms of its account with an institution before purchasing Fund
shares.  An institution purchasing or redeeming Fund shares on behalf of its
customers is responsible for transmitting orders to the Fund in accordance with
its customer agreements.

     Conflict of interest restrictions may apply to an institution's receipt of
compensation paid by the Fund in connection with the investment of fiduciary
funds in Dollar Shares or Plus Shares.  (See also "Management of the Fund --
Service Organizations," as described in the Statement of

                                      -11-
<PAGE>
 
Additional Information.) Institutions, including banks regulated by the
Comptroller of the Currency and investment advisers and other money managers
subject to the jurisdiction of the SEC, the Department of Labor or state
securities commissions, are urged to consult their legal advisors before
investing fiduciary funds in Dollar Shares or Plus Shares. (See also "Management
of the Fund -- Banking Laws," as described in the Statement of Additional
Information).


REDEMPTION OF SHARES

     Redemption orders must be transmitted to PFPC in Wilmington, Delaware in
the manner described under "Purchase of Shares."  Shares are redeemed at the net
asset value per share next determined after PFPC's receipt of the redemption
order.  While the Fund intends to use its best efforts to maintain its net asset
value per share at $1.00, the proceeds paid to a shareholder upon redemption may
be more or less than the amount invested depending upon a share's net asset
value at the time of redemption.  (Call 1-800-441-7450 (in Delaware: 302-791-
5350) to place redemption orders).

     Payment for redeemed shares for which a redemption order is accepted by
PFPC prior to Noon, Eastern time, on a Business Day is normally made in federal
funds wired to the redeeming shareholder on the same day.  Payment for
redemption orders which are received after Noon, Eastern time or on a day when
PNC Bank is closed, is normally wired in federal funds on the next day following
redemption that PNC Bank is open for business.

     The Fund shall have the right to redeem shares in any Fund account if the
value of the account is less than $4,000, after sixty-days' prior written notice
to the shareholder.  Any such redemption shall be effected at the net asset
value next determined after the redemption order is entered.  If during the
sixty-day period the shareholder increases the value of its Fund account to
$4,000 or more, no such redemption shall take place.  In addition, the Fund may
also redeem shares involuntarily under certain special circumstances described
in the Statement of Additional Information under "Additional Purchase and
Redemption Information."


SHAREHOLDER SERVICE AND DISTRIBUTION PLANS

     Institutional investors, such as banks, savings and loan associations and
other financial institutions, including affiliates of PNC Bank Corp.  ("Service
Organizations"), may purchase Dollar or Plus Shares.  Dollar and Plus Shares are
identical in all respects to Money Shares except that they bear the service fees
described below and enjoy certain exclusive voting rights on matters relating to
these fees.  The Fund will enter into an agreement with each Service
Organization which purchases Dollar Shares or Plus Shares requiring it to
provide support services to its customers who are the beneficial owners of such
shares in consideration of the Fund's payment of .25% (on an annualized basis)
of the average daily net asset value of the Dollar Shares or Plus Shares held by
the Service Organization for the benefit of customers.  Such services, which are
described more fully in the Statement of Additional Information under

                                      -12-
<PAGE>
 
"Management of the Fund Service Organizations," include aggregating and
processing purchase and redemption requests from customers and placing net
purchase and redemption orders with PFPC; processing dividend payments from the
Fund on behalf of customers; providing information periodically to customers
showing their positions in Dollar or Plus Shares; and providing sub-accounting
or the information necessary for sub-accounting with respect to Dollar or Plus
Shares beneficially owned by customers. In addition, broker-dealers purchasing
Plus Shares may be requested to provide from time to time assistance (such as
the forwarding of sales literature and advertising to their customers) in
connection with the distribution of Plus Shares. Under the terms of the
agreements, Service Organizations are required to provide to their customers a
schedule of any fees that they may charge customers in connection with their
investments in Dollar or Plus Shares. Money Shares are sold to institutions that
have not entered into servicing agreements with the Fund in connection with
their investments.


DIVIDENDS AND DISTRIBUTIONS

     The Fund declares dividends daily and distributes substantially all of its
net investment income to shareholders monthly.  Shares begin accruing dividends
on the day the purchase order for the shares is effected and continue to accrue
dividends through the day before such shares are redeemed.  Dividends are paid
monthly by check, or by wire transfer if requested in writing by the
shareholder, within five business days after the end of the month or within five
business days after a redemption of all of a shareholder's shares of a
particular class.

     Dividends are determined in the same manner for each class of shares of the
Fund.  Dollar and Plus Shares bear all the expense of fees paid to Service
Organizations, and as a result, at any given time, the dividend on Dollar or
Plus Shares will be approximately .25% lower than the dividend on Money Shares.

     Institutional shareholders may elect to have their dividends reinvested in
additional full and fractional shares of the same class of shares with respect
to which such dividends are declared at the net asset value of such shares on
the payment date.  Reinvested dividends receive the same tax treatment as
dividends paid in cash.  Reinvestment elections, and any revocations thereof,
must be made in writing to PFPC, the Fund's transfer agent, at P.O. Box 8950,
Wilmington, Delaware 19885-9628 and will become effective after its receipt by
PFPC with respect to dividends paid.


TAXES
    
     The Fund's distributions will generally constitute tax-exempt income for 
shareholders for federal income tax purposes.  It is possible, depending upon 
the Fund's investments, that a portion of the Fund's distributions could be 
taxable to shareholders as ordinary income or capital gains, but the Fund does 
not expect that this will be the case.       
    
     You should note that a portion of the exempt-interest dividends paid by the
Fund may constitute an item of tax preference for purposes of determining 
federal alternative minimum tax liability.  Exempt-interest dividends will also 
be considered along with other adjusted gross income in determining whether any 
Social Security or railroad retirement payments received by you are subject to 
federal income taxes.       
    
     The Fund intends to comply with certain state tax requirements so that the 
exempt-interest dividends derived from interest on New York Municipal 
Obligations will be exempt from New York State and New York City personal income
taxes (but not corporate franchise taxes.) Interest on indebtedness incurred by 
a shareholder to purchase or carry shares of the Fund is not deductible for 
Federal, New York State or New York City personal income tax purposes. Except as
noted with respect to New York State and New York City personal income taxes, 
dividends and distributions paid to shareholders that are derived from income on
Municipal Obligations may be taxable income under state or local law even though
all or a portion of such dividends or distributions may be derived from interest
on tax-exempt obligations that, if paid directly to shareholders, would be tax-
exempt income.     
    
     PFPC, as transfer agent, will send each Fund shareholder or its authorized 
representative an annual statement designating the amount, if any, of any 
dividends and distributions made during each year and their federal, New York 
State and New York City tax treatment.       
    
     Dividends declared in December of any year, and payable to shareholders of 
record on a specified date in December, will be deemed to have been received by 
the shareholders and paid by the Fund on December 31 of such year in the event
such dividends are actually paid during January of the following year.     
    
     You should also consult your tax adviser for further information regarding 
the federal, state and local tax consequences with respect to your specific 
situation.

                             FINANCIAL HIGHLIGHTS

     The financial highlights tables are intended to help you understand the
Fund's financial performance for the past 5 years.  Certain information reflects
financial results for a single Fund share.  The total returns in the table
represent the rate that an investor would have earned or lost on an investment
in the Fund (assuming reinvestment of all dividends and distributions).  This
information has been audited by PricewaterhouseCoopers LLP, whose report, along
with the Fund's financial statements, are incorporated by reference into the
Statement of Additional Information and included in the Annual Report, each of
which is available upon request.

                              GENERAL INFORMATION

          PIF was organized as a Delaware business trust on October 21, 1998. It
is the successor to the following five investment companies: (1) Temporary
Investment Fund, Inc. ("Temp"), (2) Trust for Federal Securities ("Fed"), (3)
Municipal Fund for Temporary Investment ("Muni"); (4) Municipal Fund for
California Investors, Inc. ("Cal Muni") and (5) Municipal Fund for New York
Investors, Inc. ("NY Muni") (each a "Predecessor Company", collectively the
"Predecessor Companies"). The Predecessor Companies were comprised of the
following portfolios (each, a "Fund" or "Predecessor Fund", collectively, the
"Funds" or "Predecessor Funds"): Temp - TempFund and TempCash; Fed - FedFund, 
T-Fund, Federal Trust Fund and Treasury Trust Fund; Muni - MuniFund and
MuniCash; Cal Muni - California Money Fund; and NY Muni - New York Money Fund.

          The Funds commenced operations as follows:  TempFund - October 1973;
TempCash - February 1984; FedFund - October 1975; T-Fund - March 1980; Federal
Trust Fund - December 1980; - Treasury Trust Fund - May 1989; MuniFund -February
1980; MuniCash - February 1984; California Money Fund - February 1983 and New
York Money Fund March 1983.

          The present fiscal year end for each of the Predecessor Companies and
their respective Funds is as follows: Temp - September 30, Fed - October 31,
Muni - November 30, Cal Muni - January 31 and NY Muni - July 31. This Statement
of Additional Information contains various charts with respect to fees and
performance information of the Predecessor Companies and/or Predecessor Funds.
    
          On February __, 1999, each of the Predecessor Funds was reorganized
into a separate series of PIF.  PIF is a no-load open-end management investment
company.  Currently, PIF offers shares of each of ten Funds.  Each Fund is a
diversified fund, with the exception of California Money Fund and New York Money
Fund which are classified as non-diversified investment companies under the 1940
Act.  Each of the Funds offers a class of Shares to institutional investors.
Each of the Funds also offers to institutional investors, such as banks, savings
and loan associations and other financial institutions ("Service
Organizations"), a separate class of shares, Dollar Shares.  Additionally,
TempFund, MuniFund, T-Fund and California Money Fund offer to Service
Organizations the following separate classes of Shares:  Administration Shares,
Cash Reserve Shares and Cash Management Shares.  TempFund, T-Fund, MuniFund, New
York Money Fund and the California Money Fund, also offer to broker dealers, who
provide assistance in the sale of shares and institutional services to their
customers, a separate class of shares, Plus Shares.

                   INVESTMENT STRATEGIES, RISKS AND POLICIES

PORTFOLIO TRANSACTIONS

          Subject to the general control of the Board of Trustees, BlackRock
Institutional Management Corporation ("BIMC", or the "Adviser"), each Fund's
investment adviser, is responsible for, makes decisions with respect to, and
places orders for all purchases and sales of portfolio securities for a Fund.
BIMC purchases portfolio securities for the Funds either directly from the
issuer or from dealers who specialize in money market instruments.  Such
purchases are usually without brokerage commissions.  In making portfolio
investments, BIMC seeks to obtain the best net price and the most favorable
execution of orders.  To the extent that the execution and price offered by more
than one dealer are comparable, BIMC may, in its discretion, effect transactions
in portfolio securities with dealers who provide the Funds with research advice
or other services.

          With respect to TempFund and TempCash, BIMC may seek to obtain an
undertaking from issuers of commercial paper or dealers selling commercial paper
to consider the repurchase of such securities from a Fund prior to their
maturity at their original cost plus interest (interest may sometimes be
adjusted to reflect the actual maturity of the securities) if BIMC believes that
those Fund's anticipated need for liquidity makes such action desirable.
Certain dealers (but not issuers) have charged and may in the future charge a
higher price for commercial paper where they undertake to repurchase prior to
maturity. The payment of a higher price in order to obtain such an undertaking
reduces the yield which might otherwise be received by a Fund on the commercial
paper.  The Company's Board of Trustees has authorized BIMC to pay a higher
price for commercial paper where it secures such an undertaking if BIMC believes
that the prepayment privilege is desirable to assure a Fund's liquidity and such
an undertaking cannot otherwise be obtained.

          Investment decisions for each Fund are made independently from those
for another of the Company's portfolios or other investment company portfolios
or accounts advised or managed by BIMC.  Such other portfolios may also invest
in the same securities as the Funds. When purchases or sales of the same
security are made at substantially the same time on behalf of such other
portfolios, transactions are averaged as to price, and available investments
allocated as to amount, in a manner which BIMC believes to be equitable to each
Fund and its customers who also are acquiring securities, including the Fund.
In some instances, this investment procedure may adversely affect the price paid
or received by a Fund or the size of the position obtained for a Fund.  To the
extent permitted by law, BIMC may aggregate the securities to be sold or
purchased for a Fund with those to be sold or purchased for such other
portfolios in order to obtain best execution.

          The Funds will not execute portfolio transactions through or acquire
portfolio securities issued by BIMC, PNC Bank, National Association ("PNC
Bank"), PFPC Inc. ("PFPC"), and Provident Distributors, Inc. ("PDI"), or any
affiliated person (as such term is defined in the Investment Company Act of 1940
(the "1940 Act")) of any of them, except to the extent permitted by the
Securities and Exchange Commission (the "SEC").  In addition, with 

                                      -2-
<PAGE>
 
respect to such transactions, securities, deposits and agreements, the Funds
will not give preference to Service Organizations with whom a Fund enters into
agreements concerning the provision of support services to customers who
beneficially own Dollar Shares, Administration Shares, Cash Reserve Shares, Cash
Management Shares and Plus Shares.

          The Funds do not intend to seek profits through short-term trading.
Each Fund's annual portfolio turnover will be relatively high, but is not
expected to have a material effect on its net income.  Each Fund's portfolio
turnover rate is expected to be zero for regulatory reporting purposes.

INVESTMENT INSTRUMENTS AND POLICIES

          The following supplements the description of the investment
instruments and/or policies which are applicable to the Funds.  In such cases
where an instrument or policy is utilized only by a specific Fund or Funds, its
applicability to the specific Fund is noted below:

          VARIABLE AND FLOATING RATE INSTRUMENTS.  TempFund, TempCash, MuniFund,
MuniCash, California Money Fund and New York Money Fund may purchase variable
and floating rate instruments.  Variable and floating rate instruments are
subject to the credit quality standards described in the Prospectuses.  In some
cases the Funds may require that the obligation to pay the principal of the
instrument be backed by a letter or line of credit or guarantee.  Such
instruments may carry stated maturities in excess of 13 months provided that the
maturity-shortening provisions stated in Rule 2a-7 are satisfied.  Although a
particular variable or floating rate demand instrument may not be actively
traded in a secondary market, in some cases, a Fund may be entitled to principal
on demand and may be able to resell such notes in the dealer market.

          Variable and floating rate demand instruments held by a Fund may have
maturities of more than 13 months provided:  (i) the Fund is entitled to the
payment of principal at any time, or during specified intervals not exceeding 13
months, upon giving the prescribed notice (which may not exceed 30 days), and
(ii) the rate of interest on such instruments is adjusted at periodic intervals
which may extend up to 13 months.  Variable and floating rate notes that do not
provide for payment within seven days may be deemed illiquid and subject to a
10% limitation on such investments.

          In determining a Fund's average weighted portfolio maturity and
whether a long-term variable or floating rate demand instrument has a remaining
maturity of 13 months or less, each instrument will be deemed by a Fund to have
a maturity equal to the longer of the period remaining until its next interest
rate adjustment or the period remaining until the principal amount can be
recovered through demand.  Variable and floating notes are not typically rated
by credit rating agencies, but their issuers must satisfy the Fund's quality and
maturity requirements.  If an issuer of such a note were to default on its
payment obligation, the Fund might be unable to dispose of the note because of
the absence of an active secondary market and might, for this or other reasons,
suffer a loss.  The Fund invests in variable or floating rate notes only when
the Adviser deems the investment to involve minimal credit risk.

                                      -3-

          REPURCHASE AGREEMENTS.  TempFund, TempCash, FedFund and T-Fund may
purchase repurchase agreements.  In a repurchase agreement, a Fund purchases
money market instruments from financial institutions, such as banks and broker-
dealers, subject to the seller's agreement to repurchase them at an agreed upon
time and price, reflecting interest on the repurchase price for the securities
subject to the repurchase agreement.  The securities subject to a repurchase
agreement may bear maturities exceeding 13 months, provided the repurchase
agreement itself matures in 13 months or less.  The seller under a repurchase
agreement will be required to maintain the value of the securities subject to
the agreement at not less than the repurchase price.  Default by the seller
would, however, expose the Fund to possible loss because of adverse market
action or delay in connection with the disposition of the underlying securities.
Collateral for a repurchase agreement may include cash items, obligations issued
by the U.S. Government or its agencies or instrumentalities or obligations rated
in the highest category by a nationally recognized statistical rating
organization (an "NRSRO").  The ratings by NRSROs represent their respective
opinions as to the quality of the obligations they undertake to rate.  Ratings,
however, are general and are not absolute standards of quality.  Consequently,
obligations with the same rating, maturity, and interest rate may have different
market prices.  The Appendix to this Statement of Additional Information
contains a description of the relevant rating symbols used by NRSROs for
commercial paper that may be purchased by each Fund.  The repurchase price under
the repurchase agreements described in the Funds' Prospectuses generally equals
the price paid by that Fund plus interest negotiated on the basis of current
short-term rates (which may be more or less than the rate on the securities
underlying the repurchase agreement).  Securities subject to repurchase
agreements will be held by the Company's custodian or sub-custodian, or in the
Federal Reserve/Treasury book-entry system.  Repurchase agreements are
considered to be loans by the Funds under the 1940 Act.     

          SECURITIES LENDING.  Each of TempFund, TempCash, FedFund and T-Fund
may lend its securities with a value of up to one-third of its total assets
(including the value of the collateral for the loan) to qualified brokers,
dealers, banks and other financial institutions for the purpose of realizing
additional net investment income through the receipt of interest on the loan.
Such loans would involve risks of delay in receiving additional collateral in
the event the value of the collateral decreased below the value of the
securities loaned or of delay in recovering the securities loaned or even loss
of rights in the collateral should the borrower of the securities fail
financially.  Loans will only be made to borrowers deemed by the Adviser to be
creditworthy.

          REVERSE REPURCHASE AGREEMENTS.  Each of TempFund, TempCash, FedFund
and T-Fund may enter into reverse repurchase agreements.  In a reverse
repurchase agreement a Fund sells a security and simultaneously commits to
repurchase that security at a future date from the buyer.  In effect, the Fund
is temporarily borrowing money at an agreed upon interest rate from the
purchaser of the security, and the security sold represents collateral for the
loan.

          A Fund's investment of the proceeds of a reverse repurchase agreement
involves the speculative factor known as leverage.  A Fund may enter into a
reverse repurchase agreement only if the interest income from investment of the
proceeds is greater than the interest expense of the transaction and the
proceeds are invested for a period no longer than the term of the agreement.  A
Fund will maintain in a segregated account, liquid securities at least equal to
its 

                                      -4-
<PAGE>
 
purchase obligations under these agreements.  The Adviser will evaluate the
creditworthiness of the other party in determining whether a Fund will enter
into a reverse repurchase agreement.  The use of reverse repurchase agreements
involves certain risks.  For example, the securities acquired by a Fund with the
proceeds of such an agreement may decline in value, although the Fund is
obligated to repurchase the securities sold to the counter party at the agreed
upon price.  In addition, the market value of the securities sold by a Fund may
decline below the repurchase price to which the Fund remains committed.

          Each of TempFund, TempCash, FedFund and T-Fund is permitted to invest
up to one-third of its total assets in reverse repurchase agreements and
securities lending transactions.  Investments in reverse repurchase agreements
and securities lending transaction will be aggregated for purposes of this
investment limitation.

          WHEN-ISSUED AND DELAYED SETTLEMENT TRANSACTIONS.  The Funds may
utilize when-issued and delayed settlement transactions.  When-issued securities
are securities purchased for delivery beyond the normal settlement date at a
stated price and yield.  Delayed settlement describes settlement of a securities
transaction in the secondary market sometime in the future.  The Fund will
generally not pay for such securities or start earning interest on them until
they are received.  Securities purchased on a when-issued or delayed settlement
basis are recorded as an asset and are subject to changes in value based upon
changes in the general level of interest rates.  When a Fund agrees to purchase
when-issued or delayed settlement securities, the custodian will set aside cash
or liquid portfolio securities equal to the amount of the commitment in a
separate account.  Normally, the custodian will set aside portfolio securities
to satisfy a purchase commitment, and in such a case that Fund may be required
subsequently to place additional assets in the separate account in order to
ensure that the value of the account remains equal to the amount of such Fund's
commitment.  It may be expected that the market value of the Fund's net assets
will fluctuate to a greater degree when it sets aside portfolio securities to
cover such purchase commitments than when it sets aside cash.  A Fund's
liquidity and ability to manage its portfolio might be affected when it sets
aside cash or portfolio securities to cover such purchase commitments.  When a
Fund engages in when-issued or delayed settlement transactions, it relies on the
seller to consummate the trade.  Failure of the seller to do so may result in a
Fund's incurring a loss or missing an opportunity to obtain a price considered
to be advantageous.  The Funds do not intend to purchase when-issued or delayed
settlement securities for speculative purposes but only in furtherance of a
Fund's investment objective.  Each Fund reserves the right to sell these
securities before the settlement date if it is deemed advisable.

          U.S. GOVERNMENT OBLIGATIONS.  Examples of the types of U.S. Government
obligations that may be held by the Funds include U.S. Treasury Bills, Treasury
Notes, and Treasury Bonds and the obligations of the Federal Housing
Administration, Farmers Home Administration, Export-Import Bank of the United
States, Small Business Administration, Government National Mortgage Association,
Federal National Mortgage Association, Federal Financing Bank, General Services
Administration, Student Loan Marketing Association, Central Bank for
Cooperatives, Federal Home Loan Banks, Federal Home Loan Mortgage Corporation,
Federal Intermediate Credit Banks, Federal Land Banks, Federal Farm Credit
Banks, Maritime 

                                      -5-

Administration, Tennessee Valley Authority, Washington D.C. Armory Board, and
International Bank for Reconstruction and Development. The Funds may also invest
in mortgage-related securities issued or guaranteed by U.S. Government agencies
and instrumentalities, including such instruments as obligations of the
Government National Mortgage Association ("GNMA"), Federal National Mortgage
Association ("FNMA") and the Federal Home Loan Mortgage Corporation ("FHLMC").

          MORTGAGE-RELATED AND OTHER ASSET-BACKED SECURITIES.  TempFund and
TempCash may purchase mortgage-related and other asset-backed securities.
Mortgage-related securities include fixed and adjustable Mortgage Pass-Through
Certificates, which provide the holder with a pro-rata share of interest and
principal payments on a pool of mortgages, ordinarily on residential properties.
There are a number of important differences among the agencies and
instrumentalities of the U.S. Government that issue mortgage-related securities
and among the securities that they issue.  Pass-Through Certificates guaranteed
by GNMA (also known as "Ginnie Maes") are guaranteed as to the timely payment of
principal and interest by GNMA, whose guarantee is backed by the full faith and
credit of the United States.  Mortgage-related securities issued by FNMA include
FNMA guaranteed Mortgage Pass-Through Certificates (also known as "Fannie Maes")
which are guaranteed as to timely payment of principal and interest by FNMA.
They are not backed by or entitled to the full faith and credit of the United
States, but are supported by the right of the FNMA to borrow from the Treasury.
Mortgage-related securities issued by FHLMC include FHLMC Mortgage Participation
Certificates (also known as "Freddie Macs").  Freddie Macs are not guaranteed by
the United States or by any Federal Home Loan Banks and do not constitute a debt
or obligation of the United States or of any Federal Home Loan Bank.  Freddie
Macs entitle the holder to timely payment of interest, which is guaranteed by
the FHLMC.  FHLMC guarantees either ultimate collection or timely payment of all
principal payments on the underlying mortgage loans.  When FHLMC does not
guarantee timely payment of principal, FHLMC is required to remit the amount due
on account of its guarantee of ultimate payment of principal no later than one
year after it becomes payable.
    
          A Fund from time to time may purchase in the secondary market (i)
certain mortgage pass-through securities packaged and master serviced by PNC
Mortgage Securities Corp. ("PNC Mortgage") (or Sears Mortgage if PNC Mortgage
succeeded to the rights and duties of Sears Mortgage) or Midland Loan Services,
Inc. ("Midland"), or (ii) mortgage-related securities containing loans or
mortgages originated by PNC Bank, National Association ("PNC Bank") or its
affiliates).  It is possible that under some circumstances, PNC Mortgage,
Midland or other affiliates could have interests that are in conflict with the
holders of these mortgage-backed securities, and such holders could have rights
against PNC Mortgage, Midland or their affiliates. For example, if PNC Mortgage 
or Midland engaged in negligence or willful misconduct in carrying out its 
duties as a master servicer, then any holder of the mortgage-backed security 
could seek recourse against PNC Mortgage or Midland. Also, as a master servicer,
PNC Mortgage or Midland may make certain representations and warranties 
regarding the quality of the mortgages and properties underlying a 
mortgage-backed security. If one or more of those representations or warranties 
is false, then the holders of the mortgage-backed securities could trigger an 
obligation of PNC Mortgage or Midland to repurchase the mortgages from the 
issuing trust. Finally, PNC Mortgage or Midland may own securities that are 
subordinate to the senior mortgage-backed securities owned by a Fund.     

          TempCash only may also invest in classes of collateralized mortgage
obligations ("CMOs") which have a remaining maturity of 13 months or less in
accordance with the requirements of Rule 2a-7 under the 1940 Act.  Each class of
a CMO, which frequently elect to be taxed as a real estate mortgage investment
conduit ("REMIC"), represents an ownership interest in, and the right to receive
a specified portion of, the cash flow consisting of interest and principal on a
pool of residential mortgage loans or mortgage pass-through securities
("Mortgage 

                                      -6-
<PAGE>
 
Assets"). CMOs are issued in multiple classes, each with a specified fixed or
floating interest rate and a final distribution date. The relative payment
rights of the various CMO classes may be structured in many ways. In most cases,
however, payments of principal are applied to the CMO classes in the order of
their respective stated maturities, so that no principal payments will be made
on a CMO class until all other classes having an earlier stated maturity date
are paid in full. These multiple class securities may be issued or guaranteed by
U.S. Government agencies or instrumentalities, including GNMA, FNMA and FHLMC,
or issued by trusts formed by private originators of, or investors in, mortgage
loans. Classes in CMOs which TempCash may hold are known as "regular" interests.
CMOs also issue "residual" interests, which in general are junior to and more
volatile than regular interests. TempCash does not intend to purchase residual
interests.

          TempFund and TempCash may also invest in non-mortgage asset-backed
securities (backed, e.g., by installment sales contracts, credit card
                    ----                                             
receivables or other assets).  Asset-backed securities are generally issued as
pass-through certificates, which represent undivided fractional ownership
interests in an underlying pool of assets, or as debt instruments, which are
also known as collateralized obligations, and are generally issued as the debt
of a special purpose entity organized solely for the purpose of owning such
assets and issuing such debt.

          The yield characteristics of certain mortgage-related and asset-backed
securities may differ from traditional debt securities.  One such major
difference is that all or a principal part of the obligations may be prepaid at
any time because the underlying assets (i.e., loans) may be prepaid at any time.
                                        ----  
As a result, a decrease in interest rates in the market may result in increases
in the level of prepayments as borrowers, particularly mortgagors, refinance and
repay their loans.  An increased prepayment rate with respect to a mortgage-
related or asset-backed security subject to such a prepayment feature will have
the effect of shortening the maturity of the security.  If a Fund has purchased
such a mortgage-related or asset-backed security at a premium, a faster than
anticipated prepayment rate could result in a loss of principal to the extent of
the premium paid.  Conversely, an increase in interest rates may result in
lengthening the anticipated maturity of such a security because expected
prepayments are reduced.  A prepayment rate that is faster than expected will
reduce the yield to maturity of such a security, while a prepayment rate that is
slower than expected may have the opposite effect of increasing yield to
maturity.

          In general, the assets supporting non-mortgage asset-backed securities
are of shorter maturity than the assets supporting mortgage-related securities.
Like other fixed-income securities, when interest rates rise the value of an
asset-backed security generally will decline; however, when interest rates
decline, the value of an asset-backed security with prepayment features may not
increase as much as that of other fixed-income securities, and, as noted above,
changes in market rates of interest may accelerate or retard prepayments and
thus affect maturities.

          These characteristics may result in a higher level of price volatility
for asset-backed securities with prepayment features under certain market
conditions.  In addition, while 

                                      -7-

the trading market for short-term mortgages and asset backed securities is
ordinarily quite liquid, in times of financial stress the trading market for
these securities sometimes becomes restricted.

          BANKING INDUSTRY OBLIGATIONS.  For purposes of TempCash's investment
policies with respect to obligations of issuers in the financial services
industry, the assets of a bank or savings institution will be deemed to include
the assets of its domestic and foreign branches.  Obligations of foreign banks
in which TempCash may invest include Eurodollar Certificates of Deposit ("ECDs")
which are U.S. dollar-denominated certificates of deposit issued by offices of
foreign and domestic banks located outside the United States; Eurodollar Time
Deposits ("ETDs") which are U.S. dollar-denominated deposits in a foreign branch
of a U.S. bank or a foreign bank; Canadian Time Deposits ("CTDs") which are
essentially the same as ETDs except they are issued by Canadian offices of major
Canadian banks; and Yankee Certificates of Deposit ("Yankee CDs") which are U.S.
dollar-denominated certificates of deposit issued by a U.S. branch of a foreign
bank and held in the United States.

          SPECIAL CONSIDERATIONS REGARDING FOREIGN INVESTMENTS.  TempCash's
investments in the obligations of foreign issuers, including foreign
governments, foreign banks and foreign branches of U.S. banks, may subject
TempCash to investment risks that are different in some respects from those of
investments in obligations of U.S. domestic issuers.  These risks may include
future unfavorable political and economic developments, possible withholding
taxes on interest income, seizure or nationalization of foreign deposits,
interest limitations, the possible establishment of exchange controls, or other
governmental restrictions which might affect the payment of principal or
interest on the securities held by the Fund.  Additionally, foreign branches of
U.S. banks and foreign banks may be subject to less stringent reserve
requirements and to different accounting, auditing, reporting and recordkeeping
requirements than those applicable to domestic branches of U.S. banks.  TempCash
will acquire securities issued by foreign issuers, including foreign
governments, foreign banks and foreign branches of U.S. banks, only when the
Fund's investment adviser believes that the risks associated with such
instruments are minimal.

          GUARANTEED INVESTMENT CONTRACTS.  TempCash may invest in guaranteed
investment contracts and similar funding agreements ("GICs").  In connection
with this TempCash makes cash contributions to a deposit fund of the insurance
company's general account.  The insurance company then credits to the Fund on a
monthly basis guaranteed interest which is based on an index (in most cases this
index is expected to be the Salomon Brothers CD Index).  The GICs provide that
this guaranteed interest will not be less than a certain minimum rate.  The
purchase price paid for a GIC becomes part of the general assets of the
insurance company, and the contract is paid from the general assets of the
insurance company.  TempCash will only purchase GICs from insurance companies
which, at the time of purchase, are rated "A+" by A.M. Best Company, have assets
of $1 billion or more and meet quality and credit standards established by the
adviser under guidelines approved by the Board of Trustees.  Generally, GICs are
not assignable or transferable without the permission of the issuing insurance
companies, and an active secondary market in some GICs does not currently exist.

          INVESTMENT COMPANY SECURITIES.  The Funds may invest in securities
issued by other open-end investment companies that invest in the type of
obligations in which such Fund may invest and that determine their net asset
value per share based upon the amortized cost or penny rounding method.
Investments in the other investment companies will cause a Fund (and,
indirectly, the Fund's shareholders) to bear proportionately the costs incurred
in connection with the other investment companies' operations.  Except as
otherwise permitted under the 1940 Act, each Fund currently intends to limit its
investments in other investment companies so that, as determined immediately
after a securities purchase is made:  (a) not more that 5% of the value of its
total assets will be invested in the securities of any one investment company;
(b) not more than 10% of its total assets will be invested in the aggregate in
securities of investment companies as a group; and (c) not more than 3% of the
outstanding voting securities of any one investment company will be owned by the
Fund.  A Fund, as discussed below in "Investment Limitations" may invest all of
its assets in a open-end investment company or series thereof with substantially
the same investment objectives, restrictions and policies as the Fund.
    
          MUNICIPAL OBLIGATIONS.  MuniFund, MuniCash, California Money Fund, New
York Money Fund TempFund and TempCash, may purchase municipal obligations.
Municipal Obligations include debt obligations issued by governmental entities
to obtain funds for various public purposes, including the construction of a
wide range of public facilities, the refunding of outstanding obligations, the
payment of general operating expenses and the extension of loans to public
institutions and facilities.  Private activity bonds that are issued by or on
behalf of public authorities to finance various privately-operated facilities
are included within the term Municipal Obligations if the interest paid thereon
is (subject to the federal alternative minimum tax) exempt from regular federal
income tax.     

          From time to time, proposals have been introduced before Congress for
the purpose of restricting or eliminating the federal income tax exemption for
interest on Municipal Obligations. For example, under the Tax Reform Act of
1986, enacted in October 1986, interest on certain private activity bonds must
be included in an investor's alternative minimum taxable income, and corporate
investors must include all tax-exempt interest in the calculation of adjusted
current earnings for purposes of determining the corporation's alternative
minimum tax liability. The Company cannot predict what legislation or
regulations, if any, may be proposed in Congress or promulgated by the
Department of Treasury as regards the federal income tax exemption of interest
on such obligations or the impact of such legislative and regulatory activity on
such exemption.

          The two principal classifications of Municipal Obligations which may
be held by the Funds are "general obligation" securities and "revenue"
securities.  General obligation securities are secured by the issuer's pledge of
its full faith, credit, and taxing power for the payment of principal and
interest.  Revenue securities are payable only from the revenues derived from a
particular facility or class of facilities or, in some cases, from the proceeds
of a special excise tax or other specific revenue source such as the user of the
facility being financed.  Revenue securities include private activity bonds
which are not payable from the unrestricted revenues of the Municipal issuer.
Consequently, the credit quality of private activity bonds is usually related to
the credit standing of the corporate user of the facility involved.

                                      -9-
<PAGE>
 
          The Funds' portfolios may also include "moral obligation" bonds, which
are normally issued by special purpose public authorities.  If the issuer of
moral obligation bonds is unable to meet its debt service obligations from
current revenues, it may draw on a reserve fund, the restoration of which is a
moral commitment but not a legal obligation of the state or municipality which
created the issuer.

          There are, of course, variations in the quality of Municipal
Obligations, both within a particular classification and between
classifications, and the yields on Municipal Obligations depend upon a variety
of factors, including general money market conditions, the financial condition
of the issuer, general conditions of the municipal bond market, the size of a
particular offering, the maturity of the obligation and the rating of the issue.
The ratings of Moody's and S&P represent their opinions as to the quality of
Municipal Obligations.  It should be emphasized, however, that ratings are
general and are not absolute standards of quality, and Municipal Obligations
with the same maturity, interest rate and rating may have different yields while
Municipal Obligations of the same maturity and interest rate with different
ratings may have the same yield.  Subsequent to its purchase by the Funds, an
issue of Municipal Obligations may cease to be rated or its rating may be
reduced below the minimum rating required for purchase by the Funds.  The
Adviser will consider such an event in determining whether the Funds should
continue to hold the obligation.

          An issuer's obligations under its Municipal Obligations are subject to
the provisions of bankruptcy, insolvency and other laws affecting the rights and
remedies of creditors, such as the federal Bankruptcy Code, and laws, if any,
which may be enacted by federal or state legislatures extending the time for
payment of principal or interest, or both, or imposing other constraints upon
enforcement of such obligations or upon the ability of municipalities to levy
taxes.  The power or ability of an issuer to meet its obligations for the
payment of interest on and principal of its Municipal Obligations may be
materially adversely affected by litigation or other conditions.

          Among other types of Municipal Obligations, the Funds may purchase
short-term General Obligation Notes, Tax Anticipation Notes, Bond Anticipation
Notes, Revenue Anticipation Notes, Tax-Exempt Commercial Paper, Construction
Loan Notes and other forms of short-term loans.  Such instruments are issued
with a short-term maturity in anticipation of the receipt of tax funds, the
proceeds of bond placements or other revenues.  In addition, the Funds may
invest in other types of tax-exempt instruments, including general obligation
and private activity bonds, provided they have remaining maturities of 13 months
or less at the time of purchase.

          MuniFund, MuniCash, California Money Fund and New York Money Fund may
hold tax-exempt derivatives which may be in the form of tender option bonds,
participations, beneficial interests in a trust, partnership interests or other
forms.  A number of different structures have been used.  For example, interests
in long-term fixed-rate Municipal Obligations, held by a bank as trustee or
custodian, are coupled with tender option, demand and other features when the
tax-exempt derivatives are created.  Together, these features entitle the holder
of the 

                                      -10-
<PAGE>
 
interest to tender (or put) the underlying Municipal Obligation to a third party
at periodic intervals and to receive the principal amount thereof. In some
cases, Municipal Obligations are represented by custodial receipts evidencing
rights to receive specific future interest payments, principal payments, or
both, on the underlying municipal securities held by the custodian. Under such
arrangements, the holder of the custodial receipt has the option to tender the
underlying municipal security at its face value to the sponsor (usually a bank
or broker dealer or other financial institution), which is paid periodic fees
equal to the difference between the bond's fixed coupon rate and the rate that
would cause the bond, coupled with the tender option, to trade at par on the
date of a rate adjustment. The Funds may hold tax-exempt derivatives, such as
participation interests and custodial receipts, for Municipal Obligations which
give the holder the right to receive payment of principal subject to the
conditions described above. The Internal Revenue Service has not ruled on
whether the interest received on tax-exempt derivatives in the form of
participation interests or custodial receipts is tax-exempt, and accordingly,
purchases of any such interests or receipts are based on the opinion of counsel
to the sponsors of such derivative securities. Neither the Funds nor the Adviser
will independently review the underlying proceedings related to the creation of
any tax-exempt derivatives or the bases for such opinion.

          Before purchasing a tax-exempt derivative for such Funds, the Adviser
is required by the Funds' procedures to conclude that the tax-exempt security
and the supporting short-term obligation involve minimal credit risks and are
Eligible Securities under the Funds' Rule 2a-7 procedures.  In evaluating the
creditworthiness of the entity obligated to purchase the tax-exempt security,
the Adviser will review periodically the entity's relevant financial
information.  Currently, the Trustees have authorized the purchase of tax-exempt
derivatives by the Funds so long as after any purchase not more than 10% of the
Funds' assets are invested in such securities.

          RESTRICTED AND OTHER ILLIQUID SECURITIES.  The SEC has adopted Rule
144A under the Securities Act of 1933 (the "1933 Act") that allows for a broader
institutional trading market for securities otherwise subject to restriction on
resale to the general public.  Rule 144A establishes a "safe harbor" from the
registration requirements of the 1933 Act for resales of certain securities to
qualified institutional buyers.  The Adviser anticipates that the market for
certain restricted securities such as institutional commercial paper will expand
further as a result of this regulation and the development of automated systems
for the trading, clearance and settlement of unregistered securities of domestic
and foreign issuers, such as the PORTAL System sponsored by the National
Association of Securities Dealers.

          The Adviser will monitor the liquidity of restricted and other
illiquid securities under the supervision of the Board of Trustees.  In reaching
liquidity decisions, the Adviser will consider, inter alia, the following
                                                ----- ----               
factors:  (1) the unregistered nature of a Rule 144A security; (2) the frequency
of trades and quotes for the Rule 144A security; (3) the number of dealers
wishing to purchase or sell the Rule 144A security and the number of other
potential purchasers; (4) dealer undertakings to make a market in the Rule 144A
security; (5) the trading markets for the Rule 144A security; and (6) the nature
of the Rule 144A security and the nature of the marketplace trades (e.g., the
                                                                    ----     
time needed to dispose of the Rule 144A security, the method of soliciting
offers and the mechanics of the transfer).

          STAND-BY COMMITMENTS.  MuniFund, MuniCash, California Money Fund and
New York Money Fund may acquire stand-by commitments.  Under a stand-by
commitment, a dealer would agree to purchase at a Fund's option specified
Municipal Obligations at their amortized cost value to the Fund plus accrued
interest, if any.  (Stand-by commitments acquired by a Fund may also be referred
to as "put" options.)  Stand-by commitments may be exercisable by a Fund at any
time before the maturity of the underlying Municipal Obligations and may be
sold, transferred, or assigned only with the instruments involved.  A Fund's
right to exercise stand-by commitments will be unconditional and 
unqualified.     

          SHORT-TERM TRADING.  Federal Trust Fund and Treasury Trust Fund may
seek profits through short-term trading and engage in short-term trading for
liquidity purposes.  Increased trading may provide greater potential for capital
gains and losses, and also involves correspondingly greater trading costs which
are borne by the Fund involved.  BIMC will consider such costs in determining
whether or not a Fund should engage in such trading.  The portfolio turnover
rate for the Funds is expected to be zero for regulatory reporting purposes.

SPECIAL CONSIDERATIONS RELATING TO CALIFORNIA MONEY FUND.

          The following information constitutes only a brief summary, does not
purport to be a complete description, and is based on information available as
of the date of this Statement of Additional Information from official statements
and prospectuses relating to securities offerings of the State of California and
various local agencies in California. While the Company has not independently
verified such information, they have no reason to believe that such information
is not correct in all material respects.

          ECONOMIC FACTORS

          FISCAL YEARS PRIOR TO 1995-96.  Pressures on the State's budget in the
late 1980's and early 1990's were caused by a combination of external economic
conditions and growth of the largest General Fund Programs - K-14 education,
health, welfare and corrections -- at rates faster than the revenue base. These
pressures could continue as the State's overall population and school age
population continue to grow, and as the State's corrections program responds to
a "Three Strikes" law enacted in 1994, which requires mandatory life prison
terms for certain third-time felony offenders. In addition, the State's health
and welfare programs are in a transition period as a result of recent federal
and State welfare reform initiatives.

          As a result of these factors and others, and especially because a
severe recession between 1990-94 reduced revenues and increased expenditures for
social welfare programs, from the late 1980's until 1992-93, the State had
periods of significant budget imbalance. During this period, expenditures
exceeded revenues in four out of six years, and the State accumulated and
sustained a budget deficit in its budget reserve, the Special Fund for Economic
Uncertainties ("SFEU") approaching $2.8 billion at its peak on June 30, 1993.

                                      -12-
<PAGE>
 
          Between the 1991-92 and 1994-95 Fiscal Years, each budget required
multibillion dollar actions to bring projected revenues and expenditures into
balance, including significant cuts in health and welfare program expenditures;
transfers of program responsibilities and funding from the State to local
governments; transfers of about $3.6 billion in annual local property tax
revenues from other local governments to local school districts, thereby
reducing State funding for schools under Proposition 98; and revenue increases
(particularly in the 1991-92 Fiscal Year budget), most of which were for a short
duration.

          Despite these budget actions, as noted, the effects of the recession
led to large, unanticipated deficits in the SFEU, as compared to projected
positive balances. By the 1993-94 Fiscal Year, the accumulated deficit was so
large that it was impractical to budget to retire such deficits in one year, so
a two-year program was implemented, using the issuance of revenue anticipation
warrants to carry a portion of the deficit over the end of the fiscal year. When
the economy failed to recover sufficiently in 1993-94, a second two-year plan
was implemented in 1994-95, again using cross-fiscal year revenue anticipation
warrants to partly finance the deficit into the 1995-96 fiscal year.

          Another consequence of the accumulated budget deficits, together with
other factors such as disbursement of funds to local school districts "borrowed"
from future fiscal years and hence not shown in the annual budget, was to
significantly reduce the State's cash resources available to pay its ongoing
obligations. When the Legislature and the Governor failed to adopt a budget for
the 1992-93 Fiscal Year by July 1, 1992, which would have allowed the State to
carry out its normal annual cash flow borrowing to replenish cash reserves, the
State Controller issued registered warrants to pay a variety of obligations
representing prior years' or continuing appropriations, and mandates from court
orders. Available funds were used to make constitutionally-mandated payments,
such as debt service on bonds and warrants. Between July 1 and September 4,
1992, when the budget was adopted, the State Controller issued a total of
approximately $3.8 billion of registered warrants.

          For several fiscal years during the recession, the State was forced to
rely on external debt markets to meet its cash needs, as a succession of notes
and revenue anticipation warrants were issued in the period from June 1992 to
July 1994, often needed to pay previously maturing notes or warrants. These
borrowings were used also in part to spread out the repayment of the accumulated
budget deficit over the end of a fiscal year, as noted earlier. The last and
largest of these borrowings was $4.0 billion of revenue anticipation warrants
which were issued in July, 1994 and matured on April 25, 1996.
    
          1995-96 THROUGH 1997-98 FISCAL YEARS     
    
          With the end of the recession, and a growing economy beginning in
1994, the State's financial condition improved markedly in the last three fiscal
years, with a combination of better than expected revenues, slowdown in growth
of social welfare programs, and continued spending restraint based on the
actions taken in earlier years. The last of the recession-induced budget
deficits was repaid, allowing the SFEU to post a positive cash balance for only
the second time in the 1990's, totaling $281 million as of June 30, 1997. The
State's cash position also     

                                      -13-
<PAGE>
 
    
returned to health, as cash flow borrowing was limited to $3 billion in 1996-97,
and no deficit borrowing has occurred over the end of these last three fiscal
years.     
    
          The economy grew strongly during these fiscal years, and as a result,
the General Fund took in substantially greater tax revenues (around $2.2 billion
in 1995-96, $1.6 billion in 1996-97 and $2.2 billion in 1997-98) than were
initially planned when the budgets were enacted. These additional funds were
largely directed to school spending as mandated by Proposition 98, and to make
up shortfalls from reduced federal health and welfare aid in 1995-96 and 1996-
97. The accumulated budget deficit from the recession years was finally
eliminated. The Department of Finance estimates that the State's budget reserve
(the SFEU) totaled $639.8 million as of June 30, 1997 and 1.782 billion as of
June 30, 1998.     
    
          1998-99 FISCAL YEAR BUDGET     
    
          When the Governor released his proposed 1998-99 Fiscal Year Budget on
January 9, 1998, he projected General Fund revenues for the 1998-99 Fiscal Year
of $55.4 billion and proposed expenditures in the same amount. By the time the
Governor released the May Revision to the 1998-99 Budget ("May Revision") on May
14, 1998, the Administration projected that revenues for the 1997-98 and 1998-99
Fiscal Years combined would be more than $4.2 billion higher than was projected
in January. The Governor proposed that most of this increased revenue be
dedicated to fund a 75% cut in the Vehicle License Fee ("VLF").     
    
          The Legislature passed the 1998-99 Budget Bill on August 11, 1998, and
the Governor signed it on August 21, 1998. Some 33 companion bills necessary to
implement the budget were also signed. In signing the Budget Bill, the Governor
used his line-item veto power to reduce expenditures by $1.360 billion from the
General Fund, and $160 million from Special Funds. Of this total, the Governor
indicated that about $250 million of vetoed funds were "set aside" to fund
programs for education. Vetoed items included education funds, salary increases
and many individual resources and capital projects.     
    
          The 1998-99 Budget Act is based on projected General Fund revenues and
transfers of $57.0 billion (after giving effect to various tax reductions
enacted in 1997 and 1998), a 4.2% increase from the revised 1997-98 figures.
Special Fund revenues were estimated at $14.3 billion.  The revenue projections
were based on the May Revision.  Economic problems overseas since that time may
affect the May Revision projections.  See "Economic Assumptions" below.     
    
          After giving effect to the Governor's vetoes, the Budget Act provides
authority for expenditures of $57.3 billion from the General Fund (a 7.3%
increase from 1997-98), $14.7 billion from Special Funds, and $3.4 billion from
bond funds.  The Budget Act projects a balance in the SFEU at June 30, 1999 (but
without including the "set aside" veto amount) of $1.255 billion, a little more
than 2% of General Fund revenues.  The Budget Act assumes the State will carry
out its normal intra-year cash flow borrowing in the amount of $1.7 billion of
revenue anticipation notes which were issued on October 1, 1998.     

                                      -14-
<PAGE>
 
    
          The most significant feature of the 1998-99 Budget was agreement on a
total of $1.4 billion of tax cuts. The central element is a bill which provides
for a phased-in reduction of the VLF. Sine the VLF is currently transferred to
cities and counties, the bill provides for the General Fund to replace the lose
revenues. Starting on January 1, 1999, the VLF will be reduced 25%, at a cost to
the General Fund of approximately $500 million in the 1998-99 Fiscal Year and
about $1 billion annually thereafter.     
    
          In addition to the cut in VLF, the1998-99 Budget includes both
temporary and permanent increase in the personal income tax dependent credit
($612 million General Fund cost in 1998-99, but less in future years), a
nonrefundable renters tax credit ($133 million), and various targeted business
tax credits ($106 million).     

          Other significant elements of the 1998-99 Budget Act are as follows:
          ------------------------------------------------------------------- 
    
          1.   Proposition 98 funding for K-12 schools is increased by $1.7
billion in General Fund moneys over revised 1997-98 levels, about $300 million
higher than the minimum Proposition 98 guaranty. An additional $600 million was
appropriated to "settle up" prior years' Proposition 98 entitlements, and was
primarily devoted to one-time uses such as block grants, deferred maintenance,
and computer and laboratory equipment. Of the 1998-99 funds, major new programs
include money for institutional and library materials deferred maintenance,
support for increasing the school year to 180 days and reduction of class sizes
in Grade 9. The Governor held $250 million of education funds which were vetoed
as set-aside for enactment of additional reforms. Overall, per-pupil spending
for K-12 schools under Proposition 98 is increased to $5,696, more than one
third higher than the level in the last recession year of 1993-4. The Budget
also includes $250 million a repayment of prior years' loans to schools, as part
of the settlement of the CTA v. Gould lawsuit.     
                         ------------         
    
          2.   Funding for higher education increased substantially above the
level called for in the Governor's four-year compact. General Fund support was
increased by $340 million (15.6%) for the University of California and $267
million (14.1%) for the California State University system. In addition,
Community Colleges received a $300 million (6.6%) increase under Proposition 
98.     
    
          3.   The Budget includes increased funding for health, welfare and
social services programs. A 4.9% grant increase was included in the basic
welfare grants, the first increase in those grants in 9 years. Future increases
will depend on sufficient General Fund revenue to trigger the phased costs in
VLF described above.     
    
          4.   Funding for the judiciary and criminal justice programs increased
by about 11% over 1997-98, primarily to reflect increased State support for
local trial courts and rising prison population.     
    
          5.   Various other highlights of the Budget included new funding for
resources projects, dedication of $376 million of General Fund moneys for
capital outlay projects, funding of a 3% State employee salary increase, funding
of 2,000 new Department of Transportation     

                                      -15-
<PAGE>
 
    
positions to accelerate transportation construction projects and funding of the
Infrastructure and Economic Development Bank ($50 million).     
    
          6.   The State of California received approximately $167 million of
federal reimbursements to offset costs related to the incarceration of
undocumented alien felons for federal fiscal year 1997. The State anticipates
receiving approximately $195 million in federal reimbursements for federal
fiscal year 1998.     
    
          After the Budget Act was signed, and prior to the close of the
Legislative session on August 31, 1998, the Legislature passed a variety of
fiscal bills.  The Governor had until September 30, 1998 to sign or veto these
bills.  The bills with the most significant fiscal impact which the Governor
signed include $235 million for certain water system improvements in Southern
California, $243 million for the State's share of the purchase of
environmentally sensitive forest lands, $178 million for state prisons, $160
million for housing assistance ($40 million of which was included in the 1998-99
Budget Act and an additional $120 million reflected in Proposition 1A), and $125
million for juvenile facilities.  The Governor also signed bills totaling $223
million for education programs which were part of the Governor's $250 million
veto "set aside," and $32 million for local governments fiscal relief.  In
addition, he signed a bill reducing by $577 million the State's obligation to
contribute to the State Teachers' Retirement System in the 1998-99 Fiscal 
Year.     
    
          Based solely on the legislation enacted, on a net basis, the reserve
for June 30, 1999, was reduced by $256 million.  On the other hand, 1997-98
revenues have been increased by $160 million.  The revised June 30, 1999,
reserve is projected to be $1,159 million or $96 million below the level
projected at the Budget Act.  The reserve projected in the Budget Act was $1,255
million.  It is important to emphasize that the new reserve level is based on
1998-99 revenue and expenditure assumptions as of the Budget Act except to
augment for legislation signed after the budget enactment.  These assumptions
will not be updated until the 1999-00 Governor's Budget is released or January
10, 1999.  In November, 1998, the Legislative Analyst's Office released a report
predicting that General Fund revenues for 1998-99 would be somewhat lower, and
expenditures somewhat higher, than the Budget Act forecasts, but the net
variance would be within the projected $1.2 billion year-end reserve 
amount.     

          OTHER MATTERS.  On December 6, 1994, Orange County, California and its
Investment Pool (the "Pool") filed for bankruptcy under Chapter 9 of the United
States Bankruptcy Code.  The subsequent restructuring led to the sale of
substantially all of the Pool's portfolio and resulted in losses estimated to be
approximately $1.7 billion (or approximately 22% of amounts deposited by the
Pool investors).  Approximately 187 California public entities -- substantially
all of which are public agencies within the county -- had various bonds, notes
or other forms of indebtedness outstanding.  In some instances the proceeds of
such indebtedness were invested in the Pool.

          In April, 1996, the County emerged from bankruptcy after closing on a
$900 million recovery bond transaction. At that time, the County and its
financial advisors stated that the County had emerged from the bankruptcy
without any structural fiscal problems and assured

                                      -16-
<PAGE>
 
    
that the County would not slip back into bankruptcy. However, for many of the
cities, schools and special districts that lost money in the County portfolio,
repayment remains contingent on the outcome of litigation which is pending
against investment firms and other finance professionals. Settlement discussions
involving a number of defendants have occurred and a number of agreements have
been executed, however, until any such agreements become final and any remaining
litigation is resolved, it is impossible to determine the ultimate impact of the
bankruptcy and its aftermath on these various agencies and their claims.     

          CONSTITUTIONAL, LEGISLATIVE AND OTHER FACTORS.

          Certain California constitutional amendments, legislative measures,
executive orders, administrative regulations and voter initiatives could produce
the adverse effects described below, among others.

          REVENUE DISTRIBUTION. Certain Debt Obligations in the Portfolio may be
obligations of issuers which rely in whole or in part on California State
revenues for payment of these obligations. Property tax revenues and a portion
of the State's general fund surplus are distributed to counties, cities and
their various taxing entities and the State assumes certain obligations
theretofore paid out of local funds. Whether and to what extent a portion of the
State's general fund will be distributed in the future to counties, cities and
their various entities is unclear.

          HEALTH CARE LEGISLATION. Certain Debt Obligations in the Portfolio may
be obligations which are payable solely from the revenues of health care
institutions. Certain provisions under California law may adversely affect these
revenues and, consequently, payment on those Debt Obligations.

          The federally sponsored Medicaid program for health care services to
eligible welfare beneficiaries in California is known as the Medi-Cal program.
Historically, the Medi-Cal program has provided for a cost-based system of
reimbursement for inpatient care furnished to Medi-Cal beneficiaries by any
hospital wanting to participate in the Medi-Cal program, provided such hospital
met applicable requirements for participation. California law now provides that
the State of California shall selectively contract with hospitals to provide
acute inpatient services to Medi-Cal patients. Medi-Cal contracts currently
apply only to acute inpatient services. Generally, such selective contracting is
made on a flat per diem payment basis for all services to Medi-Cal
beneficiaries, and generally such payment has not increased in relation to
inflation, costs or other factors. Other reductions or limitations may be
imposed on payment for services rendered to Medi-Cal beneficiaries in the
future.

          Under this approach, in most geographical areas of California, only
those hospitals which enter into a Medi-Cal contract with the State of
California will be paid for non-emergency acute inpatient services rendered to
Medi-Cal beneficiaries. The State may also terminate these contracts without
notice under certain circumstances and is obligated to make contractual payments
only to the extent the California legislature appropriates adequate funding
therefor.

                                      -17-
<PAGE>
 
          California enacted legislation in 1982 that authorizes private health
plans and insurers to contract directly with hospitals for services to
beneficiaries on negotiated terms. Some insurers have introduced plans known as
"preferred provider organizations" ("PPOs"), which offer financial incentives
for subscribers who use only the hospitals which contract with the plan. Under
an exclusive provider plan, which includes most health maintenance organizations
("HMOs"), private payors limit coverage to those services provided by selected
hospitals. Discounts offered to HMOs and PPOs may result in payment to the
contracting hospital of less than actual cost and the volume of patients
directed to a hospital under an HMO or PPO contract may vary significantly from
projections. Often, HMO or PPO contracts are enforceable for a stated term,
regardless of provider losses or of bankruptcy of the respective HMO or PPO. It
is expected that failure to execute and maintain such PPO and HMO contracts
would reduce a hospital's patient base or gross revenues. Conversely,
participation may maintain or increase the patient base, but may result in
reduced payment and lower net income to the contracting hospitals.

          These Debt Obligations may also be insured by the State of California
pursuant to an insurance program implemented by the Office of Statewide Health
Planning and Development for health facility construction loans. If a default
occurs on insured Debt Obligations, the State Treasurer will issue debentures
payable out of a reserve fund established under the insurance program or will
pay principal and interest on an unaccelerated basis from unappropriated State
funds. At the request of the Office of Statewide Health Planning and
Development, Arthur D. Little, Inc. prepared a study in December 1983, to
evaluate the adequacy of the reserve fund established under the insurance
program and based on certain formulations and assumptions found the reserve fund
substantially underfunded. In September of 1986, Arthur D. Little, Inc. prepared
an update of the study and concluded that an additional 10% reserve be
established for "multi-level" facilities. For the balance of the reserve fund,
the update recommended maintaining the current reserve calculation method. In
March of 1990, Arthur D. Little, Inc. prepared a further review of the study and
recommended that separate reserves continue to be established for "multi-level"
facilities at a reserve level consistent with those that would be required by an
insurance company.

          MORTGAGES AND DEEDS.  Certain Debt Obligations in the Portfolio may be
obligations which are secured in whole or in part by a mortgage or deed of trust
on real property.  California has five principal statutory provisions which
limit the remedies of a creditor secured by a mortgage or deed of trust.  Two
statutes limit the creditor's right to obtain a deficiency judgment, one
limitation being based on the method of foreclosure and the other on the type of
debt secured.  Under the former, a deficiency judgment is barred when the
foreclosure is accomplished by means of a nonjudicial trustee's sale.  Under the
latter, a deficiency judgment is barred when the foreclosed mortgage or deed of
trust secures certain purchase money obligations.  Another California statute,
commonly known as the "one form of action" rule, requires creditors secured by
real property to exhaust their real property security by foreclosure before
bringing a personal action against the debtor.  The fourth statutory provision
limits any deficiency judgment obtained by a creditor secured by real property
following a judicial sale of such property to the excess of the outstanding debt
over the fair value of the property at the time 

                                      -18-
<PAGE>
 
of the sale, thus preventing the creditor from obtaining a large deficiency
judgment against the debtor as the result of low bids at a judicial sale. The
fifth statutory provision gives the debtor the right to redeem the real property
from any judicial foreclosure sale as to which a deficiency judgment may be
ordered against the debtor.

          Upon the default of a mortgage or deed of trust with respect to
California real property, the creditor's nonjudicial foreclosure rights under
the power of sale contained in the mortgage or deed of trust are subject to the
constraints imposed by California law upon transfers of title to real property
by private power of sale. During the three-month period beginning with the
filing of a formal notice of default, the debtor is entitled to reinstate the
mortgage by making any overdue payments. Under standard loan servicing
procedures, the filing of the formal notice of default does not occur unless at
least three full monthly payments have become due and remain unpaid. The power
of sale is exercised by posting and publishing a notice of sale for at least 20
days after expiration of the three-month reinstatement period. The debtor may
reinstate the mortgage, in the manner described above, up to five business days
prior to the scheduled sale date. Therefore, the effective minimum period for
foreclosing on a mortgage could be in excess of seven months after the initial
default. Such time delays in collections could disrupt the flow of revenues
available to an issuer for the payment of debt service on the outstanding
obligations if such defaults occur with respect to a substantial number of
mortgages or deeds of trust securing an issuer's obligations.

          In addition, a court could find that there is sufficient involvement
of the issuer in the nonjudicial sale of property securing a mortgage for such
private sale to constitute "state action," and could hold that the 
private-right-of-sale proceedings violate the due process requirements of the
Federal or State Constitutions, consequently preventing an issuer from using the
nonjudicial foreclosure remedy described above.

          Certain Debt Obligations in the Portfolio may be obligations which
finance the acquisition of single family home mortgages for low and moderate
income mortgagors. These obligations may be payable solely from revenues derived
from the home mortgages, and are subject to California's statutory limitations
described above applicable to obligations secured by real property. Under
California antideficiency legislation, there is no personal recourse against a
mortgagor of a single family residence purchased with the loan secured by the
mortgage, regardless of whether the creditor chooses judicial or nonjudicial
foreclosure.

          Under California law, mortgage loans secured by single-family owner-
occupied dwellings may be prepaid at any time. Prepayment charges on such
mortgage loans may be imposed only with respect to voluntary prepayments made
during the first five years during the term of the mortgage loan, and then only
if the borrower prepays an amount in excess of 20% of the original principal
amount of the mortgage loan in a 12-month period; a prepayment charge cannot in
any event exceed six months' advance interest on the amount prepaid during the
12-month period in excess of 20% of the original principal amount of the loan.
This limitation could affect the flow of revenues available to an issuer for
debt service on the outstanding debt obligations which financed such home
mortgages.

<PAGE>
 
          PROPOSITION 13.  Certain of the Debt Obligations may be obligations of
issuers who rely in whole or in part on ad valorem real property taxes as a
source of revenue. On June 6, 1978, California voters approved an amendment to
the California Constitution known as Proposition 13, which added Article XIIIA
to the California Constitution. The effect of Article XIIIA was to limit ad
valorem taxes on real property and to restrict the ability of taxing entities to
increase real property tax revenues.

          Section 1 of Article XIIIA, as amended, limits the maximum ad valorem
tax on real property to 1% of full cash value to be collected by the counties
and apportioned according to law. The 1% limitation does not apply to ad valorem
taxes or special assessments to pay the interest and redemption charges on any
bonded indebtedness for the acquisition or improvement of real property approved
by two-thirds of the votes cast by the voters voting on the proposition. Section
2 of Article XIIIA defines "full cash value" to mean "the County Assessor's
valuation of real property as shown on the 1975/76 tax bill under 'full cash
value' or, thereafter, the appraised value of real property when purchased,
newly constructed, or a change in ownership has occurred after the 1975
assessment." The full cash value may be adjusted annually to reflect inflation
at a rate not to exceed 2% per year, or reduction in the consumer price index or
comparable local data, or reduced in the event of declining property value
caused by damage, destruction or other factors.

          Legislation enacted by the California Legislature to implement Article
XIIIA provides that notwithstanding any other law, local agencies may not levy
any ad valorem property tax except to pay debt service on indebtedness approved
by the voters prior to July 1, 1978, and that each county will levy the maximum
tax permitted by Article XIIIA.

          PROPOSITION 9.  On November 6, 1979, an initiative known as
"Proposition 9" or the "Gann Initiative" was approved by the California voters,
which added Article XIIIB to the California Constitution. Under Article XIIIB,
State and local governmental entities have an annual "appropriations limit" and
are not allowed to spend certain moneys called "appropriations subject to
limitation" in an amount higher than the "appropriations limit." Article XIIIB
does not affect the appropriation of moneys which are excluded from the
definition of "appropriations subject to limitation," including debt service on
indebtedness existing or authorized as of January 1, 1979, or bonded
indebtedness subsequently approved by the voters. In general terms, the
"appropriations limit" is required to be based on certain 1978/79 expenditures,
and is to be adjusted annually to reflect changes in consumer prices,
population, and certain services provided by these entities. Article XIIIB also
provides that if these entities' revenues in any year exceed the amounts
permitted to be spent, the excess is to be returned by revising tax rates or fee
schedules over the subsequent two years.

          PROPOSITION 98.  On November 8, 1988, voters of the State approved
Proposition 98, a combined initiative constitutional amendment and statute
called the "Classroom Instructional Improvement and Accountability Act."
Proposition 98 changed State funding of public education below the university
level and the operation of the State Appropriations Limit, primarily by
guaranteeing K-14 schools a minimum share of General Fund revenues. Under
Proposition 98 (modified by Proposition 111 as discussed below), K-14 schools
are guaranteed

                                      -20-
<PAGE>
 
the greater of (a) in general, a fixed percent of General Fund revenues ("Test
1"), (b) the amount appropriated to K-14 schools in the prior year, adjusted for
changes in the cost of living (measured as in Article XIII B by reference to
State per capita personal income) and enrollment ("Test 2"), or (c) a third
test, which would replace Test 2 in any year when the percentage growth in per
capita General Fund revenues from the prior year plus one half of one percent is
less than the percentage growth in State per capita personal income ("Test 3").
Under Test 3, schools would receive the amount appropriated in the prior year
adjusted for changes in enrollment and per capita General Fund revenues, plus an
additional small adjustment factor.  If Test 3 is used in any year, the
difference between Test 3 and Test 2 would become a "credit" to schools which
would be the basis of payments in future years when per capita General Fund
revenue growth exceeds per capita personal income growth.

  Proposition 98 permits the Legislature -- by two-thirds vote of both houses,
with the Governor's concurrence -- to suspend the K-14 schools' minimum funding
formula for a one-year period.  Proposition 98 also contains provisions
transferring certain State tax revenues in excess of the Article XIII B limit to
K-14 schools.
    
  During the recession years of the early 1990s, General Fund revenues for
several years were less than originally projected, so that the original
Proposition 98 appropriations turned out to be higher than the minimum
percentage provided in the law.  The Legislature responded to these developments
by designating the "extra" Proposition 98 payments in one year as a "loan" from
future years' Proposition 98 entitlements, and also intended that the "extra"
payments would not be included in the Proposition 98 "base" for calculating
future years' entitlements.  In 1992, a lawsuit was filed, California Teachers'
                                                           --------------------
Association v. Gould, which challenged the validity of these off-budget loans.
- --------------------                                                           
During the course of this litigation, a trial court determined that almost $2
billion in "loans" which had been provided to school districts during the
recession violated the constitutional protection of support for public
education.  A settlement was reached on April 12, 1996 which ensures that future
school funding will not be in jeopardy over repayment of these so-called 
loans.     

  PROPOSITION 111.  On June 30, 1989, the California Legislature enacted Senate
Constitutional Amendment 1, a proposed modification of the California
Constitution to alter the spending limit and the education funding provisions of
Proposition 98.  Senate Constitutional Amendment 1 -- on the June 5, 1990 ballot
as Proposition 111 -- was approved by the voters and took effect on July 1,
1990.  Among a number of important provisions, Proposition 111 recalculated
spending limits for the State and for local governments, allowed greater annual
increases in the limits, allowed the averaging of two years' tax revenues before
requiring action regarding excess tax revenues, reduced the amount of the
funding guarantee in recession years for school districts and community college
districts (but with a floor of 40.9 percent of State general fund tax revenues),
removed the provision of Proposition 98 which included excess moneys transferred
to school districts and community college districts in the base calculation for
the next year, limited the amount of State tax revenue over the limit which
would be transferred to school districts and community college districts, and
exempted increased gasoline taxes and truck weight fees from the State
appropriations limit.  Additionally, Proposition 111 exempted from the State
appropriations limit funding for capital outlays.

          PROPOSITION 62. On November 4, 1986, California voters approved an
initiative statute known as Proposition 62. This initiative provided the
following:

          1.   Requires that any tax for general governmental purposes imposed
     by local governments be approved by resolution or ordinance adopted by a
     two-thirds vote of the governmental entity's legislative body and by a
     majority vote of the electorate of the governmental entity;

          2.   Requires that any special tax (defined as taxes levied for other
     than general governmental purposes) imposed by a local governmental entity
     be approved by a two-thirds vote of the voters within that jurisdiction;

          3.   Restricts the use of revenues from a special tax to the purposes
     or for the service for which the special tax was imposed;

          4.   Prohibits the imposition of ad valorem taxes on real property by
     local governmental entities except as permitted by Article XIIIA;

          5.   Prohibits the imposition of transaction taxes and sales taxes on
     the sale of real property by local governments;

          6.   Requires that any tax imposed by a local government on or after
     August 1, 1985 be ratified by a majority vote of the electorate within two
     years of the adoption of the initiative;

          7.   Requires that, in the event a local government fails to comply
     with the provisions of this measure, a reduction in the amount of property
     tax revenue allocated to such local government occurs in an amount equal to
     the revenues received by such entity attributable to the tax levied in
     violation of the initiative; and

          8.   Permits these provisions to be amended exclusively by the voters
     of the State of California.
    
          In September 1988, the California Court of Appeal in City of
                                                               -------
Westminster v. County of Orange, 204 Cal.App. 3d 623, 215 Cal.Rptr. 511
- -------------------------------
(Cal.Ct.App. 1988), held that Proposition 62 is unconstitutional to the extent
that it requires a general tax by a general law city, enacted on or after August
1, 1985 and prior to the effective date of Proposition 62, to be subject to
approval by a majority of voters. The Court held that the California
Constitution prohibits the imposition of a requirement that local tax measures
be submitted to the electorate by either referendum or initiative. It is
impossible to predict the impact of this decision on charter cities, on special
taxes or on new taxes imposed after the effective date of Proposition 62. The
California Court of Appeal in City of Woodlake v. Logan, (1991) 230 Cal.App.3d
                              -------------------------
1058, subsequently held that Proposition 62's popular vote requirements for
future local taxes also

City of Woodlake decision as erroneous.  The Court did not determine the

of the Supreme Court's decision on charter cities or on taxes imposed in

  In McBrearty v. City of Brawley, 59 Cal. App.4th 1441, 69 Cal. Rptr. 2d 862
     ----------------------------                                            
(Cal. Ct. App. 1997), the Court of Appeal held that the city of Brawley must
either hold an election or cease collection of utility taxes that were not
submitted to a vote.  In 1991, the City of Brawley adopted an ordinance imposing
a utility tax on its residents and began collecting the tax without first
seeking voter approval.  In 1996, the taxpayer petitioned for writ of mandate
contending that Proposition 62 required the city to submit its utility tax on
residents to vote of local electorate.  The trial court issued a writ of
mandamus and the city appealed.     
    
  First, the Court of Appeal held that the taxpayer's cause of action accrued
for statute of limitation purposes at the time of the Guardino decision rather
                                                      --------                
than at the time when the city adopted the tax ordinance which was July 1991.
Second, the Court held that the voter approval requirement in Proposition 62 was
not an invalid mechanism under the state constitution for the involvement of the
exectorate in the legislative process.  Third, the Court rejected the city's
argument that Guardino should only be applied on a prospective basis.  Finally,
              --------                                                         
the Court held Proposition 218 (see discussion below) did not impliedly protect
any local general taxes imposed prior January 21, 1995 against challenge.     
    
  Assembly Bill 1362 (Mazzoni), introduced February 28, 1997, which would have
made the Guardino decision inapplicable to any tax first imposed or increased by
         --------                                                               
an ordinance or resolution adopted before December 14, 1995, was vetoed by the
Governor on December 11, 1997.  The California State Senate had passed the Bill
on September 8, 1997 and the California State Assembly had passed the Bill on
September 8, 1997.  It is not clear whether the Bill, if enacted, would have
been constitutional as a non-voted amendment to Proposition 62 or as a non-voted
change to Proposition 62's operative date.     

  PROPOSITION 218.  On November 5, 1996,the voters of the State approved
Proposition 218, a constitutional initiative, entitled the "Right to Vote on
Taxes Act" ("Proposition 218").  Proposition 218 adds Articles XIII C and XIII D
to the California Constitution and contains a number of interrelated provisions
affecting the ability of local governments to levy and collect both existing and
future taxes, assessments, fees and charges.  Proposition 218 became effective
on November 6, 1996.  The Sponsors are unable to predict whether and to what
extent Proposition 218 may be held to be constitutional or how its terms will be
interpreted and applied by the courts.  However, if upheld, Proposition 218
could

                                      -23-
<PAGE>
 
substantially restrict certain local governments' ability to raise future
revenues and could subject certain existing sources of revenue to reduction or
repeal, and increase local government costs to hold elections, calculate fees
and assessments, notify the public and defend local government fees and
assessments in court.

  Article XIII C of Proposition 218 requires majority voter approval for the
imposition, extension or increase of general taxes and two-thirds voter approval
for the imposition, extension or increase of special taxes, including special
taxes deposited into a local government's general fund.  Proposition 218 also
provides that any general tax imposed, extended or increased without voter
approval by any local government on or after January 1, 1995 and prior to
November 6, 1996 shall continue to be imposed only if approved by a majority
vote in an election held within two years of November 6, 1996.
    
  Article XIII C of Proposition 218 also expressly extends the initiative power
to give voters the power to reduce or repeal local taxes, assessments, fees and
charges, regardless of the date such taxes, assessments, fees or charges were
imposed.  This extension of the initiative power to some extent
constitutionalizes the March 6, 1995 State Supreme Court decision in Rossi v.
                                                                     --------

State constitution does not preclude the repeal, including the prospective
repeal, of a tax ordinance by an initiative, as contrasted with the State
constitutional prohibition on referendum powers regarding statutes and
ordinances which impose a tax.  Generally, the initiative process enables
California voters to enact legislation upon obtaining requisite voter approval
at a general election.  Proposition 218 extends the authority stated in Rossi v.
                                                                        --------

assessments, fees and charges, which had previously been considered
administrative rather than legislative matters and therefore beyond the
initiative power.     

  The initiative power granted under Article XIII C of Proposition 218, by its
terms, applies to all local taxes, assessments, fees and charges and is not
limited to local taxes, assessments, fees and charges that are property related.

  Article XIII D of Proposition 218 adds several new requirements making it
generally more difficult for local agencies to levy and maintain "assessments"
for municipal services and programs.  "Assessment" is defined to mean any levy
or charge upon real property for a special benefit conferred upon the real
property.

  Article XIII D of Proposition 218 also adds several provisions affecting
"fees" and "charges" which are defined as "any levy other than an ad valorem
tax, a special tax, or an assessment, imposed by a local government upon a
parcel or upon a person as an incident of property ownership, including a user
fee or charge for a property related service."  All new and, after June 30,
1997, existing property related fees and charges must conform to requirements
prohibiting, among other things, fees and charges which (i) generate revenues
exceeding the funds required to provide the property related service, (ii) are
used for any purpose other than those for which the fees and charges are
imposed, (iii) are for a service not actually used by, or immediately available
to, the owner of the property in question, or (iv) are used for general

                                      -24-

governmental services, including police, fire or library services, where the
service is available to the public at large in substantially the same manner as
it is to property owners.  Further, before any property related fee or charge
may be imposed or increased, written notice must be given to the record owner of
each parcel of land affected by such fee or charges.  The local government must
then hold a hearing upon the proposed imposition or increase of such property
based fee, and if written protests against the proposal are presented by a
majority of the owners of the identified parcels, the local government may not
impose or increase the fee or charge.  Moreover, except for fees or charges for
sewer, water and refuse collection services, no property related fee or charge
may be imposed or increased without majority approval by the property owners
subject to the fee or charge or, at the option of the local agency, two-thirds
voter approval by the electorate residing in the affected area.

     PROPOSITION 87. On November 8, 1988, California voters approved Proposition
87. Proposition 87 amended Article XVI, Section 16, of the California
Constitution by authorizing the California Legislature to prohibit redevelopment
agencies from receiving any of the property tax revenue raised by increased
property tax rates levied to repay bonded indebtedness of local governments
which is approved by voters on or after January 1, 1989.

SPECIAL CONSIDERATIONS WITH RESPECT TO NEW YORK MONEY FUND

     Some of the significant financial considerations relating to investments in
New York Municipal Obligations are summarized below. This summary information is
not intended to be a complete description and is principally derived from
official statements relating to issues of New York Municipal Obligations that
were available prior to the date of this Statement of Additional Information.
The accuracy and completeness of the information contained in those official
statements have not been independently verified.

     STATE ECONOMY.  New York is the third most populous state in the nation and
has a relatively high level of personal wealth.  The State's economy is diverse
with a comparatively large share of the nation's finance, insurance,
transportation, communications and services employment, and a very small share
of the nation's farming and mining activity.  The State's location and its
excellent air transport facilities and natural harbors have made it an important
link in international commerce.  Travel and tourism constitute an important part
of the economy.  Like the rest of the nation, New York has a declining
proportion of its workforce engaged in manufacturing, and an increasing
proportion engaged in service industries.

     The State has historically been one of the wealthiest states in the nation.
For decades, however, the State has grown more slowly than the nation as a
whole, gradually eroding its relative economic position. State per capita
personal income has historically been significantly higher than the national
average, although the ratio has varied substantially. Because New York City (the
"City") is a regional employment center for a multi-state region, State personal
income measured on a residence basis understates the relative importance of the
State to the national economy and the size of the base to which State taxation
applies.

                                      -25-
<PAGE>
 
          The State economic forecast has been raised slightly from the enacted
budget forecast.  Continued growth is projected in 1998 and 1999 for employment,
wages, and personal income, although the growth rates of personal income and
wages are expected to be lower than those in 1997.  The growth of personal
income is projected to decline from 5.7 percent in 1997 to 4.8 percent in 1998
and 4.2 percent in 1999, in part because growth in bonus payments is expected to
slow down, a distinct shift from the torrid rate of the last few years.  Overall
employment growth is expected to be 1.9 percent in 1998, the strongest in a
decade, but will drop to 1.0 percent in 1999, reflecting the slowing growth in
the national economy, continued restraint in governmental spending, and
restructuring in the health care, social service, and banking sectors.

          There can be no assurance that the State economy will not experience
worse-than-predicted results, with corresponding material and adverse effects on
the State's projections of receipts and disbursements.

          STATE BUDGET. The State Constitution requires the governor (the
"Governor") to submit to the State legislature (the "Legislature") a balanced
executive budget which contains a complete plan of expenditures for the ensuing
fiscal year and all moneys and revenues estimated to be available therefor,
accompanied by bills containing all proposed appropriations or reappropriations
and any new or modified revenue measures to be enacted in connection with the
executive budget. The entire plan constitutes the proposed State financial plan
for that fiscal year. The Governor is required to submit to the Legislature
quarterly budget updates which include a revised cash-basis state financial
plan, and an explanation of any changes from the previous state financial plan.

          State law requires the Governor to propose a balanced budget each
year.  In recent years, the State has closed projected budget gaps of $5.0
billion (1995-96), $3.9 billion (1996-97), $2.3 billion (1997-98), and less than
$1 billion (1998-99).  The State, as a part of the 1998-99 Executive Budget
projections submitted to the Legislature in February 1998, projected a 1999-00
General Fund budget gap of approximately $1.7 billion and a 2000-01 gap of $3.7
billion.  As a result of changes made in the 1998-99 enacted budget, the 1999-00
gap is now expected to be roughly $1.3 billion, or about $400 million less than
previously projected, after application of reserves created as part of the 1998-
99 budget process.  Such reserves would not be available against subsequent year
imbalances.

          Sustained growth in the State's economy could contribute to closing
projected budget gaps over the next several years, both in terms of higher-than-
projected tax receipts and in lower-than-expected entitlement spending.
However, the State's projections in 1999-00 currently assume actions to achieve
$600 million in lower disbursements and $250 million in additional receipts from
the settlement of State claims against the tobacco industry.  Consistent with
past practice, the projections do not include any costs associated with new
collective bargaining agreements after the expiration of the current round of
contracts at the end of the 1998-99 fiscal year.  The State expects that the
1990-00 Financial Plan will achieve savings from initiatives by State agencies
to deliver services more efficiently, workforce management efforts, maximization
of federal and non-General Fund spending offsets, and other actions necessary to
bring projected disbursements and receipts into balance.

                                      -26-
<PAGE>
 
          The State will formally update its outyear projections of receipts and
disbursements for the 2000-01 and 2001-02 fiscal years as a part of the 1999-00
Executive Budget process, as required by law.  The revised expectations for
years 2000-01 and 2001-02 will reflect the cumulative impact of tax reductions
and spending commitments enacted over the last several years as well as new
1999-00 Executive Budget recommendations.  The School Tax Relief Program
("STAR") program, which dedicates a portion of personal income tax receipts to
fund school tax reductions, has a significant impact on General Fund receipts.
STAR is projected to reduce personal income tax revenues available to the
General Fund by an estimated $1.3 billion in 2000-01.  Measured from the 1998-99
base, scheduled reductions to estate and gift, sales and other taxes, reflecting
tax cuts enacted in 1997-98 and 1998-99, will lower General Fund taxes and fees
by an estimated $1.8 billion in 2000-01.  Disbursement projections for the
outyears currently assume additional outlays for school aid, Medicaid, welfare
reform, mental health community reinvestment, and other multi-year spending
commitments in law.

          On September 11, 1997, the New York State Comptroller issued a report
which noted that the ability to deal with future budget gaps could become a
significant issue in the State's 2000-2001 fiscal year, when the cost of tax
cuts increases by $1.9 billion.  The report contained projections that, based on
current economic conditions and current law for taxes and spending, showed a gap
in the 2000-2001 State fiscal year of $5.6 billion and of $7.4 billion in the
2001-2002 State fiscal year.  The report noted that these gaps would be smaller
if recurring spending reductions produce savings in earlier years.  The State
Comptroller has also stated that if Wall Street earnings moderate and the State
experiences a moderate recession, the gap for the 2001-2002 State fiscal year
could grow to nearly $12 billion.

          The State's current fiscal year began on April 1, 1998 and ends on
March 31, 1999 and is referred to herein as the State's 1998-99 fiscal year.
The Legislature adopted the debt service component of the State budget for the
1998-99 fiscal year on March 30, 1998 and the remainder of the budget on April
18, 1998.  In the period prior to adoption of the budget for the current fiscal
year, the Legislature also enacted appropriations to permit the State to
continue its operations and provide for other purposes.  On April 25, 1998, the
Governor vetoed certain items that the Legislature added to the Executive
Budget.  The Legislature had not overridden any of the Governor's vetoes as of
the start of the legislative recess on June 19, 1998 (under the State
Constitution, the Legislature can override one or more of the Governor's vetoes
with the approval of two-thirds of the members of each house).

          General Fund disbursements in 1998-99 are now projected to grow by
$2.43 billion over 1997-98 levels, or $690 million more than proposed in the
Governor's Executive Budget, as amended. The change in General Fund
disbursements from the Executive Budget to the enacted budget reflects
legislative additions (net of the value of the Governor's vetoes), actions taken
at the end of the regular legislative session, as well as spending that was
originally anticipated to occur in 1997-98 but is now expected to occur in 1998-
99. The State projects that the 1998-99 State Financial Plan is balanced on a
cash basis, with an estimated reserve for future needs of $761 million.

                                      -27-
<PAGE>
 
          The State's enacted budget includes several new multi-year tax
reduction initiatives, including acceleration of State-funded property and local
income tax relief for senior citizens under the STAR, expansion of the child
care income-tax credit for middle-income families, a phased-in reduction of the
general business tax, and reduction of several other taxes and fees, including
an accelerated phase-out of assessments on medical providers.  The enacted
budget also provides for significant increases in spending for public schools,
special education programs, and for the State and City university systems.  It
also allocates $50 million for a new Debt Reduction Reserve Fund ("DRRF") that
may eventually be used to pay debt service costs on or to prepay outstanding
State-supported bonds.
    
          The 1998-99 State Financial Plan projects a closing balance in the
General Fund of $1.42 billion that is comprised of a reserve of $761 million
available for future needs, a balance of $400 million in the Tax Stabilization
Reserve Fund ("TSRF"), a balance of $158 million in the Community Projects Fund
("CPF"), and a balance of $100 million in the Contingency Reserve Fund ("CRF").
The TSRF can be used in the event of an unanticipated General Fund cash
operating deficit, as provided under the State Constitution and State Finance
Law. The CPF is used to finance various legislative and executive initiatives.
The CRF provides resource to help finance any extraordinary litigation costs
during the fiscal year.     

          The forecast of General Fund receipts in 1998-99 incorporates several
Executive Budget tax proposals that, if enacted, would further reduce receipts
otherwise available to the General Fund by approximately $700 million during
1998-99.  The Executive Budget proposes accelerating school tax relief for
senior citizens under STAR, which is projected to reduce General Fund receipts
by $537 million in 1998-99.  The proposed reduction supplements STAR tax
reductions already scheduled in law, which are projected at $187 million in
1998-99.  The Budget also proposes several new tax-cut initiatives and other
funding changes that are projected to further reduce receipts available to the
General Fund by over $200 million.  These initiatives include reducing the fee
to register passenger motor vehicles and earmarking a larger portion of such
fees to dedicated funds and other purposes; extending the number of weeks in
which certain clothing purchases are exempt from sales taxes; more fully
conforming State law to reflect recent Federal changes in estate taxes;
continuing lower pari-mutuel tax rates; and accelerating scheduled property tax
relief for farmers from 1999 to 1998.  In addition to the specific tax and fee
reductions discussed above, the Executive Budget also proposes establishing a
reserve of $100 million to permit the acceleration into 1998-99 of other tax
reductions that are otherwise scheduled in law for implementation in future
fiscal years.
    
          The Division of the Budget ("DOB") estimates that the 1998-99
Financial Plan includes approximately $64 million in non-recurring resources,
comprising less than two-tenths of one percent of General Fund disbursements.
The non-recurring resources projected for use in 1998-99 consist of $27 million
in retroactive federal welfare reimbursements for family assistance recipients
with HIV/AIDS, $25 million in receipts from the Housing Finance Agency that were
originally anticipated in 1997-98, and $10 million in other measures, including
$5 million in asset sales.     

                                      -28-
<PAGE>
 
          Disbursements from Capital Projects funds in 1998-99 are estimated at
$4.82 billion, or $1.07 billion higher than 1997-98.  The proposed spending plan
includes:  $2.51 billion in disbursements for transportation purposes, including
the State and local highway and bridge program; $815 million for environmental
activities; $379 million for correctional services; $228 million for the State
University of New York ("SUNY") and the City University of New York ("CUNY");
$290 million for mental hygiene projects; and $375 million for CEFAP.
Approximately 28 percent of capital projects are proposed to be financed by
"pay-as-you-go" resources.  State-supported bond issuances finance 46 percent of
capital projects, with federal grants financing the remaining 26 percent.

          Many complex political, social and economic forces influence the
State's economy and finances, which may in turn affect the State's Financial
Plan.  These forces may affect the State unpredictably from fiscal year to
fiscal year and are influenced by governments, institutions, and organizations
that are not subject to the State's control.  The State Financial Plan is also
necessarily based upon forecasts of national and State economic activity.
Economic forecasts have frequently failed to predict accurately the timing and
magnitude of changes in the national and the State economies.  The DOB believes
that its projections of receipts and disbursements relating to the current State
Financial Plan, and the assumptions on which they are based, are reasonable.
Actual results, however, could differ materially and adversely from their
projections, and those projections may be changed materially and adversely from
time to time.

          In the past, the State has taken management actions and made use of
internal sources to address potential State financial plan shortfalls, and the
DOB believes it could take similar actions should variances occur in its
projections for the current fiscal year.

          RECENT FINANCIAL RESULTS. The General Fund is the principal operating
fund of the State and is used to account for all financial transactions, except
those required to be accounted for in another fund. It is the State's largest
fund and receives almost all State taxes and other resources not dedicated to
particular purposes.

          On March 31, 1998, the State recorded, on a GAAP-basis, its first-
ever, accumulated positive balance in its General Fund.  This "accumulated
surplus" was $567 million.  The improvement in the State's GAAP position is
attributable, in part, to the cash surplus recorded at the end of the State's
1997-98 fiscal year.  Much of that surplus is reserved for future requirements,
but a portion is being used to meet spending needs in 1998-99.  Thus, the State
expects some deterioration in its GAAP position, but expects to maintain a
positive GAAP balance through the end of the current fiscal year.

          The State completed its 1997-98 fiscal year with a combined
Governmental Funds operating surplus of $1.80 billion, which included an
operating surplus in the General Fund of $1.56 billion, in Capital Projects
Funds of $232 million and in Special Revenue Funds of $49 million, offset in
part by an operating deficit of $43 million in Debt Service Funds.

          The State reported a General Fund operating surplus of $1.56 billion
for the 1997-98 fiscal year, as compared to an operating surplus of $1.93
billion for the 1996-97 fiscal year. 

                                      -29-
<PAGE>
 
As a result, the State reported an accumulated surplus of $567 million in the
General Fund for the first time since it began reporting its operations on a
GAAP-basis. The 1997-98 fiscal year operating surplus reflects several major
factors, including the cash-basis operating surplus resulting from the higher-
than-anticipated personal income tax receipts, an increase in taxes receivable
of $681 million, an increase in other assets of $195 million and a decrease in
pension liabilities of $144 million. This was partially offset by an increase in
payables to local governments of $270 million and tax refunds payable of $147
million.

          DEBT LIMITS AND OUTSTANDING DEBT. There are a number of methods by
which the State of New York may incur debt. Under the State Constitution, the
State may not, with limited exceptions for emergencies, undertake long-term
general obligation borrowing (i.e., borrowing for more than one year) unless the
                              ----- 
borrowing is authorized in a specific amount for a single work or purpose by the
Legislature and approved by the voters. There is no limitation on the amount of
long-term general obligation debt that may be so authorized and subsequently
incurred by the State.

          The State may undertake short-term borrowings without voter approval
(i) in anticipation of the receipt of taxes and revenues, by issuing tax and
revenue anticipation notes, and (ii) in anticipation of the receipt of proceeds
from the sale of duly authorized but unissued general obligation bonds, by
issuing bond anticipation notes.  The State may also, pursuant to specific
constitutional authorization, directly guarantee certain obligations of the
State of New York's authorities and public benefit corporations ("Authorities").
Payments of debt service on New York State general obligation and New York
State-guaranteed bonds and notes are legally enforceable obligations of the
State of New York.

          The State employs additional long-term financing mechanisms, lease-
purchase and contractual-obligation financings, which involve obligations of
public authorities or municipalities that are State-supported but are not
general obligations of the State.  Under these financing arrangements, certain
public authorities and municipalities have issued obligations to finance the
construction and rehabilitation of facilities or the acquisition and
rehabilitation of equipment, and expect to meet their debt service requirements
through the receipt of rental or other contractual payments made by the State.
Although these financing arrangements involve a contractual agreement by the
State to make payments to a public authority, municipality or other entity, the
State's obligation to make such payments is generally expressly made subject to
appropriation by the Legislature and the actual availability of money to the
State for making the payments.  The State has also entered into a contractual-
obligation financing arrangement with the LGAC to restructure the way the State
makes certain local aid payments.

          In February 1997, the Job Development Authority ("JDA") issued
approximately $85 million of State-guaranteed bonds to refinance certain of its
outstanding bonds and notes in order to restructure and improve JDA's capital
structure.  Due to concerns regarding the economic viability of its programs,
JDA's loan and loan guarantee activities had been suspended since the Governor
took office in 1995.  As a result of the structural imbalances in JDA's capital
structure, and defaults in its loan portfolio and loan guarantee program
incurred between 1991 and 1996, JDA would have experienced a debt service cash
flow shortfall had it not completed

                                      -30-
<PAGE>
     
its recent refinancing. JDA anticipates that it will transact additional
refinancings in 1999, 2000 and 2003 to complete its long-term plan of finance
and further alleviate cash flow imbalances which are likely to occur in future
years. JDA recently resumed its lending activities under a revised set of
lending programs and underwriting guidelines.     

          On January 13, 1992, Standard & Poor's Ratings Services ("Standard &
Poor's") reduced its ratings on the State's general obligation bonds from A to
A- and, in addition, reduced its ratings on the State's moral obligation, lease
purchase, guaranteed and contractual obligation debt.  On August 28, 1997,
Standard & Poor's revised its ratings on the State's general obligation bonds
from A- to A and revised its ratings on the State's moral obligation, lease
purchase, guaranteed and contractual obligation debt.  On March 2, 1998,
Standard & Poor's affirmed its A rating on the State's outstanding bonds.

          On January 6, 1992, Moody's Investors Service, Inc. ("Moody's")
reduced its ratings on outstanding limited-liability State lease purchase and
contractual obligations from A to Baa1.  On February 28, 1994, Moody's
reconfirmed its A rating on the State's general obligation long-term
indebtedness.  On March 20, 1998, Moody's assigned the highest commercial paper
rating of P-1 to the short-term notes of the State.  On July 6, 1998, Moody's
assigned an A2 rating with a stable outlook to the State's general obligations.

          The State anticipates that its capital programs will be financed, in
part, through borrowings by the State and its public authorities in the 1998-99
fiscal year. Information on the State's five-year Capital Program and Financing
Plan for the 1998-99 through 2002-03 fiscal years, updated to reflect actions
taken in the 1998-99 State budget (the "Plan"), was released on July 30, 1998.
The projection of State borrowings for the 1998-99 fiscal year is subject to
change as market conditions, interest rates and other factors vary throughout
the fiscal year.    

          The State expects to issue $528 million in general obligation bonds
(including $154 million for purposes of redeeming outstanding BANs) and $154
million in general obligation commercial paper.  The State also anticipates the
issuance of up to a total of $419 million in Certificates of Participation to
finance equipment purchases (including costs of issuance, reserve funds, and
other costs) during the 1998-99 fiscal year.  Of this amount, it is anticipated
that approximately $191 million will be issued to finance agency equipment
acquisitions, including amounts to address Statewide technology issues related
to Year 2000 compliance.  Approximately $228 million will also be issued to
finance equipment acquisitions for welfare reform-related information technology
systems.

          Borrowings by public authorities pursuant to lease-purchase and
contractual-obligation financings for capital programs of the State are
projected to total approximately $2.93 billion, including costs of issuance,
reserve funds, and other costs, net of anticipated refundings and other
adjustments in 1998-99.
    
          As a part of the Plan, changes were proposed to the State's borrowing
plan, including:  the delay in the issuance of COPs to finance welfare
information systems until 1998-     

                                      -31-

99 to permit a thorough assessment of needs; and the elimination of issuances
for the CEFAP to reflect the proposed conversion of that bond-financed program
to pay-as-you-go financing.     

          New York State has never defaulted on any of its general obligation
indebtedness or its obligations under lease-purchase or contractual-obligation
financing arrangements and has never been called upon to make any direct
payments pursuant to its guarantees.
    
          LITIGATION. Certain litigation pending against New York State or its
officers or employees could have a substantial or long-term adverse effect on
New York State finances. Among the more significant of these cases are those
that involve (1) the validity of agreements and treaties by which various Indian
tribes transferred title to New York State of certain land in central and
upstate New York; (2) certain aspects of New York State's Medicaid policies,
including its rates, regulations and procedures; (3) action against New York
State and New York City officials alleging inadequate shelter allowances to
maintain proper housing; (4) alleged responsibility of New York State officials
to assist in remedying racial segregation in the City of Yonkers; (5) challenges
to regulations promulgated by the Superintendent of Insurance establishing
certain excess medical malpractice premium rates; (6) challenges to the
constitutionality of Public Health Law 2807-d, which imposes a gross receipts
tax from certain patient care services; (7) action seeking enforcement of
certain sales and excise taxes and tobacco products and motor fuel sold to non-
Indian consumers on Indian reservations; and (8) a challenge to the Governor's
application of his constitutional line item veto authority.     

          Several actions challenging the constitutionality of legislation
enacted during the 1990 legislative session which changed actuarial funding
methods for determining state and local contributions to state employee
retirement systems have been decided against the State.  As a result, the
Comptroller developed a plan to restore the State's retirement systems to prior
funding levels.  Such funding is expected to exceed prior levels by $116 million
in fiscal 1996-97, $193 million in fiscal 1997-98, peaking at $241 million in
fiscal 1998-99.  Beginning in fiscal 2001-02, State contributions required under
the Comptroller's plan are projected to be less than that required under the
prior funding method.  As a result of the United States Supreme Court decision
in the case of State of Delaware v. State of New York, on January 21, 1994, the
State entered into a settlement agreement with various parties.  Pursuant to all
agreements executed in connection with the action, the State was required to
make aggregate payments of $351.4 million.  Annual payments to the various
parties will continue through the State's 2002-03 fiscal year in amounts which
will not exceed $48.4 million in any fiscal year subsequent to the State's 1994-
95 fiscal year.  Litigation challenging the constitutionality of the treatment
of certain moneys held in a reserve fund was settled in June 1996 and certain
amounts in a Supplemental Reserve Fund previously credited by the State against
prior State and local pension contributions will be paid in 1998.
    
          The legal proceedings noted above involve State finances, State
programs and miscellaneous cure rights, tort, real property and contract claims
in which the State is a defendant and the monetary damages sought are
substantial, generally in excess of $100 million.  These proceedings could
affect adversely the financial condition of the State in the 1998-99 fiscal year
or thereafter.  Adverse developments in these proceedings, other proceedings for
which     

                                      -32-
<PAGE>
 
    
there are unanticipated, unfavorable and material judgments, or the
initiation of new proceedings could affect the ability of the State to maintain
a balanced financial plan.  An adverse decision in any of these proceedings
could exceed the amount of the reserve established in the State's financial plan
for the payment of judgments and, therefore, could affect the ability of the
State to maintain a balanced financial plan.     

          Although other litigation is pending against New York State, except as
described herein, no current litigation involves New York State's authority, as
a matter of law, to contract indebtedness, issue its obligations, or pay such
indebtedness when it matures, or affects New York State's power or ability, as a
matter of law, to impose or collect significant amounts of taxes and revenues.

          AUTHORITIES. The fiscal stability of New York State is related, in
part, to the fiscal stability of its Authorities, which generally have
responsibility for financing, constructing and operating revenue-producing
public benefit facilities. Authorities are not subject to the constitutional
restrictions on the incurrence of debt which apply to the State itself, and may
issue bonds and notes within the amounts of, and as otherwise restricted by,
their legislative authorization. The State's access to the public credit markets
could be impaired, and the market price of its outstanding debt may be
materially and adversely affected, if any of the Authorities were to default on
their respective obligations, particularly with respect to debt that is State-
supported or State-related.

          Authorities are generally supported by revenues generated by the
projects financed or operated, such as fares, user fees on bridges, highway
tolls and rentals for dormitory rooms and housing.  In recent years, however,
New York State has provided financial assistance through appropriations, in some
cases of a recurring nature, to certain of the Authorities for operating and
other expenses and, in fulfillment of its commitments on moral obligation
indebtedness or otherwise, for debt service.  This operating assistance is
expected to continue to be required in future years.  In addition, certain
statutory arrangements provide for State local assistance payments otherwise
payable to localities to be made under certain circumstances to certain
Authorities.  The State has no obligation to provide additional assistance to
localities whose local assistance payments have been paid to Authorities under
these arrangements.  However, in the event that such local assistance payments
are so diverted, the affected localities could seek additional State funds.

          NEW YORK CITY AND OTHER LOCALITIES. The fiscal health of the State may
also be impacted by the fiscal health of its localities, particularly the City,
which has required and continues to require significant financial assistance
from the State. The City depends on State aid both to enable the City to balance
its budget and to meet its cash requirements. There can be no assurance that
there will not be reductions in State aid to the City from amounts currently
projected or that State budgets will be adopted by the April 1 statutory
deadline or that any such reductions or delays will not have adverse effects on
the City's cash flow or expenditures. In addition, the Federal budget
negotiation process could result in a reduction in or a delay in the receipt of
Federal grants which could have additional adverse effects on the City's cash
flow or revenues.

          In 1975, New York City suffered a fiscal crisis that impaired the
borrowing ability of both the City and New York State.  In that year the City
lost access to the public credit markets.  The City was not able to sell short-
term notes to the public again until 1979.  In 1975, Standard & Poor's suspended
its A rating of City bonds.  This suspension remained in effect until March
1981, at which time the City received an investment grade rating of BBB from
Standard & Poor's.

          On July 2, 1985, Standard & Poor's revised its rating of City bonds
upward to BBB+ and on November 19, 1987, to A-. On February 3, 1998 and again on
May 27, 1998, Standard & Poor's assigned a BBB+ rating to the City's general
obligation debt and placed the ratings on CreditWatch with positive
implications.

          Moody's ratings of City bonds were revised in November 1981 from B (in
effect since 1977) to Ba1, in November 1983 to Baa, in December 1985 to Baa1, in
May 1988 to A and again in February 1991 to Baa1.  On February 25, 1998, Moody's
upgraded nearly $28 billion of the City's general obligations from Baa1 to A3.
On June 9, 1998, Moody's again assigned on A3 rating to the City's general
obligations and stated that its outlook was stable.

          New York City is heavily dependent on New York State and federal
assistance to cover insufficiencies in its revenues.  There can be no assurance
that in the future federal and State assistance will enable the City to make up
its budget deficits.  To help alleviate the City's financial difficulties, the
Legislature created the Municipal Assistance Corporation ("MAC") in 1975.  Since
its creation, MAC has provided, among other things, financing assistance to the
City by refunding maturing City short-term debt and transferring to the City
funds received from sales of MAC bonds and notes.  MAC is authorized to issue
bonds and notes payable from certain stock transfer tax revenues, from the
City's portion of the State sales tax derived in the City and, subject to
certain prior claims, from State per capita aid otherwise payable by the State
to the City.  Failure by the State to continue the imposition of such taxes, the
reduction of the rate of such taxes to rates less than those in effect on July
2, 1975, failure by the State to pay such aid revenues and the reduction of such
aid revenues below a specified level are included among the events of default in
the resolutions authorizing MAC's long-term debt.  The occurrence of an event of
default may result in the acceleration of the maturity of all or a portion of
MAC's debt.  MAC bonds and notes constitute general obligations of MAC and do
not constitute an enforceable obligation or debt of either the State or the
City.

          Since 1975, the City's financial condition has been subject to
oversight and review by the New York State Financial Control Board (the "Control
Board") and since 1978 the City's financial statements have been audited by
independent accounting firms.  To be eligible for guarantees and assistance, the
City is required during a "control period" to submit annually for Control Board
approval, and when a control period is not in effect for Control Board review, a
financial plan for the next four fiscal years covering the City and certain
agencies showing balanced budgets determined in accordance with GAAP.  New York
State also established the Office of the State Deputy Comptroller for New York
City ("OSDC") to assist the Control Board in exercising its powers and
responsibilities.  On June 30, 1986, the City satisfied the statutory

                                      -34-
<PAGE>
 
requirements for termination of the control period.  This means that the Control
Board's powers of approval are suspended, but the Board continues to have
oversight responsibilities.
    
          On June 10, 1997, the City submitted to the Control Board the
Financial Plan (the "1998-2001 Financial Plan") for the 1998 through 2001 fiscal
years, relating to the City, the Board of Education ("BOE") and CUNY and
reflected the City's expense and capital budgets for the 1998 fiscal year, which
were adopted on June 6, 1997.  The 1998-2001 Financial Plan projected revenues
and expenditures for the 1998 fiscal year balanced in accordance with  GAAP.
The 1998-99 Financial Plan projects General Fund receipts (including transfers
from other funds) of $36.22 billion, an increase of $1.02 billion over the
estimated 1997-1998 level.  Recurring growth in the State General Fund tax base
is projected to be approximately six percent during 1998-99, after adjusting for
tax law and administrative changes.  This growth rate is lower than the rates
for 1996-97 or currently estimated for 1997-98, but roughly equivalent to the
rate for 1995-96.     

          The 1998-99 forecast for user taxes and fees also reflects the impact
of scheduled tax reductions that will lower receipts by $38 million, as well as
the impact of two Executive Budget proposals that are projected to lower
receipts by an additional $79 million.  The first proposal would divert $30
million in motor vehicle registration fees from the General Fund to the
Dedicated Highway and Bridge Trust Fund; the second would reduce fees for motor
vehicle registrations, which would further lower receipts by $49 million.  The
underlying growth of receipts in this category is projected at 4 percent, after
adjusting for these scheduled and recommended changes.

          In comparison to the current fiscal year, business tax receipts are
projected to decline slightly in 1998-99, falling from $4.98 million to $4.96
billion.  The decline in this category is largely attributable to scheduled tax
reductions.  In total, collections for corporation and utility taxes and the
petroleum business tax are projected to fall by $107 million from 1997-98.  The
decline in receipts in these categories is partially offset by growth in the
corporation franchise, insurance and bank taxes, which are projected to grow by
$88 million over the current fiscal year.

          The Financial Plan is projected to show a GAAP-basis surplus of $131
million for 1997-98 and a GAAP-basis deficit of $1.3 billion for 1998-99 in the
General Fund, primarily as a result of the use of the 1997-98 cash surplus.  In
1998-99, the General Fund GAAP Financial Plan shows total revenues of $34.68
billion, total expenditures of $35.94 billion, and net other financing sources
and uses of $42 million.
    
          Although the City has maintained balanced budgets in each of its last
eighteen fiscal years and is projected to achieve balanced operating results for
the 1999 fiscal year, there can be no assurance that the gap-closing actions
proposed in the 1998-2001 Financial Plan can be successfully implemented or that
the City will maintain a balanced budget in future years without additional
State aid, revenue increases or expenditure reductions.  Additional tax
increases and reductions in essential City services could adversely affect the
City's economic base.     

                                      -35-
<PAGE>
 
          The projections set forth in the 1998-2001 Financial Plan were based
on various assumptions and contingencies which are uncertain and which may not
materialize.  Changes in major assumptions could significantly affect the City's
ability to balance its budget as required by State law and to meet its annual
cash flow and financing requirements.  Such assumptions and contingencies
include the condition of the regional and local economies, the impact on real
estate tax revenues of the real estate market, wage increases for City employees
consistent with those assumed in the 1998-2001 Financial Plan, employment
growth, the ability to implement proposed reductions in City personnel and other
cost reduction initiatives, the ability of the Health and Hospitals Corporation
and the BOE to take actions to offset reduced revenues, the ability to complete
revenue generating transactions, provision of State and Federal aid and mandate
relief and the impact on City revenues and expenditures of Federal and State
welfare reform and any future legislation affecting Medicare or other
entitlements.

          Implementation of the 1998-2001 Financial Plan is also dependent upon
the City's ability to market its securities successfully.  The City's financing
program for fiscal years 1998 through 2001 contemplates the issuance of $5.7
billion of general obligation bonds and $5.7 billion of bonds to be issued by
the proposed New York City Transitional Finance Authority (the "Finance
Authority") to finance City capital projects.  The Finance Authority, was
created as part of the City's effort to assist in keeping the City's
indebtedness within the forecast level of the constitutional restrictions on the
amount of debt the City is authorized to incur. Despite this additional
financing mechanism, the City currently projects that, if no further action is
taken, it will reach its debt limit in City fiscal year 1999-2000.  Indebtedness
subject to the constitutional debt limit includes liability on capital contracts
that are expected to be funded with general obligation bonds, as well as general
obligation bonds.  On June 2, 1997, an action was commenced seeking a
declaratory judgment declaring the legislation establishing the Transitional
Finance Authority to be unconstitutional.  If such legislation were voided,
projected contracts for the City capital projects would exceed the City's debt
limit during fiscal year 1997-98.  Future developments concerning the City or
entities issuing debt for the benefit of the City, and public discussion of such
developments, as well as prevailing market conditions and securities credit
ratings, may affect the ability or cost to sell securities issued by the City or
such entities and may also affect the market for their outstanding securities.

          The City Comptroller and other agencies and public officials have
issued reports and made public statements which, among other things, state that
projected revenues and expenditures may be different from those forecast in the
City's financial plans.  It is reasonable to expect that such reports and
statements will continue to be issued and to engender public comment.
    
          The City since 1981 has fully satisfied its seasonal financing needs
in the public credit markets, repaying all short-term obligations within their
fiscal year of issuance.  Although the City's 1998 fiscal year financial plan
projected $2.4 billion of seasonal financing for the 1998 fiscal year, the City
expected to undertake only approximately $1.4 billion of seasonal financing.
The City issued $2.4 billion of short-term obligations in fiscal year 1997.
Seasonal financing requirements for the 1996 fiscal year increased to $2.4
billion from $2.2 billion and     

                                      -36-
<PAGE>
 
    
$1.75 billion in the 1995 and 1994 fiscal years, respectively. Seasonal
financing requirements were $1.4 billion in the 1993 fiscal year. The delay in
the adoption of the State's budget in certain past fiscal years has required the
City to issue short-term notes in amounts exceeding those expected early in such
fiscal years.     

          Certain localities, in addition to the City, have experienced
financial problems and have requested and received additional New York State
assistance during the last several State fiscal years.  The potential impact on
the State of any future requests by localities for additional assistance is not
included in the State's projections of its receipts and disbursements for the
1997-98 fiscal year.

          Fiscal difficulties experienced by the City of Yonkers ("Yonkers")
resulted in the re-establishment of the Financial Control Board for the City of
Yonkers (the "Yonkers Board") by New York State in 1984. The Yonkers Board is
charged with oversight of the fiscal affairs of Yonkers.  Future actions taken
by the State to assist Yonkers could result in increased State expenditures for
extraordinary local assistance.

          Beginning in 1990, the City of Troy experienced a series of budgetary
deficits that resulted in the establishment of a Supervisory Board for the City
of Troy in 1994.  The Supervisory Board's powers were increased in 1995, when
Troy MAC was created to help Troy avoid default on certain obligations.  The
legislation creating Troy MAC prohibits the city of Troy from seeking federal
bankruptcy protection while Troy MAC bonds are outstanding.  Troy MAC has issued
bonds to effect a restructuring of the City of Troy's obligations.
    
          Eighteen municipalities received extraordinary assistance during the
1996 legislative session through $50 million in special appropriations targeted
for distressed cities, and that was largely continued in 1997.  Twenty-eight
municipalities were scheduled to share in more than $32 million in targeted
unrestricted aid allocated in the 1997-98 budget.  An additional $21 million
will be dispersed among all cities, towns and villages, a 3.97% increase in
General Purpose State Aid.     

          The 1998-99 budget includes an additional $29.4 million in
unrestricted aid targeted to 57 municipalities across the State.  Other
assistance for municipalities with special needs totals more than $25.6 million.
Twelve upstate cities will receive $24.2 million in one-time assistance from a
cash flow acceleration of State aid.
    
          Municipalities and school districts have engaged in substantial short-
term and long-term borrowings. In 1996, the total indebtedness of all localities
in the State other than New York City was approximately $20.0 billion. A small
portion (approximately $77.2 million) of that indebtedness represented borrowing
to finance budgetary deficits and was issued pursuant to enabling State
legislation. State law requires the Comptroller to review and make
recommendations concerning the budgets of those local government units other
than New York City that are authorized by State law to issue debt to finance
deficits during the period that such deficit financing is outstanding.    

                                      -37-
<PAGE>
 
          From time to time, federal expenditure reductions could reduce, or in
some cases eliminate, federal funding of some local programs and accordingly
might impose substantial increased expenditure requirements on affected
localities.  If the State, the City or any of the Authorities were to suffer
serious financial difficulties jeopardizing their respective access to the
public credit markets, the marketability of notes and bonds issued by localities
within the State could be adversely affected.  Localities also face anticipated
and potential problems resulting from certain pending litigation, judicial
decisions and long-range economic trends.  Long-range potential problems of
declining urban population, increasing expenditures and other economic trends
could adversely affect localities and require increasing the State assistance in
the future.

          YEAR 2000 COMPLIANCE. The State is currently addressing "Year 2000"
data processing compliance issues. The Year 2000 compliance issue ("Y2K") arises
because most computer software programs allocate two digits to the data field
for "year" on the assumption that the first two digits will be "19". Such
programs will thus interpret the year 2000 as the year 1900 absent
reprogramming. Y2K could impact both the ability to enter data into computer
programs and the ability of such programs to correctly process data.

          The Office for Technology is monitoring compliance on a quarterly
basis and is providing assistance and assigning resources to accelerate
compliance for mission critical systems, with most compliance testing expected
to be completed by mid-1999.  There can be no guarantee, however, that all of
the State's mission-critical and high-priority computer systems will be Year
2000 compliant and that there will not be an adverse impact upon State
operations or State finances as a result.


                            INVESTMENT LIMITATIONS
                                        
          The following is a complete list of investment limitations and
policies applicable to each of the Funds or, as indicated below, to specific
Funds, that may not changed without the affirmative votes of the holders of a
majority of each Fund's outstanding shares (as defined below under
"Miscellaneous"):

          1. A Fund may not borrow money or issue senior securities except to
the extent permitted under the 1940 Act.

          2. A Fund may not act as an underwriter of securities. A Fund will not
be an underwriter for purposes of this limitation if it purchases securities in
transactions in which the Fund would not be deemed to be an underwriter for
purposes of the Securities Act of 1933.

          3. A Fund may not make loans. The purchase of debt obligations, the
lending of portfolio securities and the entry into repurchase agreements are not
treated as the making of loans for purposes of this limitation.

                                      -38-
<PAGE>
 
          4.  A Fund may not purchase or sell real estate. The purchase of
securities secured by real estate or interests therein are not considered to be
a purchase of real estate for the purposes of the limitation.
   
          5.  A Fund may not purchase or sell commodities or commodities
contracts.
 
          6.  A Fund may, notwithstanding any other fundamental investment
limitations, invest all of its assets in a single open-end investment company or
series thereof with substantially the same investment objectives, restrictions
and policies as the Fund.      

          7.  With respect to TempFund, TempCash, MuniFund and MuniCash only: A
              -------------------------------------------------------------- 
Fund may not purchase the securities of any issuer if as a result more than 5%
of the value of the Fund's assets would be invested in the securities of such
issuer except that up to 25% of the value of the Fund's assets may be invested
without regard to this 5% limitation.

          8.  With respect to TempFund only. TempFund may not purchase any
              -----------------------------       
securities which would cause 25% or more of the value of its total assets at the
time of such purchase to be invested in the securities of one or more issuers
conducting their principal business activities in the same industry, provided
that (a) there is no limitation with respect to investments in U.S. Treasury
Bills, other obligations issued or guaranteed by the federal government, its
agencies and instrumentalities, certificates of deposit, and bankers'
acceptances and (b) neither all finance companies, as a group, nor all utility
companies, as a group, are considered a single industry for purposes of this
policy. The Fund interprets the exception for "certificates of deposit, and
bankers' acceptances" in this fundamental policy to include other similar
obligations of domestic banks.

          9.  With respect to TempCash only: TempCash may not purchase any
              -----------------------------   
securities which would cause, at the time of purchase, less than 25% of the
value of its total assets to be invested in obligations of issuers in the
financial services industry or in obligations, such as repurchase agreements,
secured by such obligations (unless the Fund is in a temporary defensive
position) or which would cause, at the time of purchase, 25% or more of the
value of its total assets to be invested in the obligations of issuers in any
other industry, provided that (a) there is no limitation with respect to
investments in U.S. Treasury Bills and other obligations issued or guaranteed by
the federal government, its agencies and instrumentalities and (b) neither all
finance companies, as a group, nor all utility companies, as a group, are
considered a single industry for purposes of this policy.

          10. With respect to California Money Fund and New York Money Fund
              -------------------------------------------------------------
only: Each of these Funds may not purchase any securities which would cause 25%
- ----
or more of the Fund's total assets at the time of purchase to be invested in the
securities of one or more issuers conducting their principal business activities
in the same industry, provided that there is no limitation with respect to
obligations issued or guaranteed by the U.S. government, any state or territory
of the United States, or any of their agencies, instrumentalities or political
subdivisions.

                                      -39-
<PAGE>
 
    
          The following is a list of non-fundamental investment limitations
applicable to each of the Funds or, as indicated below, to specific Funds.
Unlike a fundamental limitation, a non-fundamental investment limitation may be
changed without the approval of shareholders.     

          1.  A Fund may not acquire any other investment company or investment
company security except in connection with a merger, consolidation,
reorganization or acquisition of assets or where otherwise permitted by the 1940
Act.

          2.  With Respect to MuniFund, MuniCash, Cal Money and NY Money only:
              ---------------------------------------------------------------
The Fund may not invest more than 10% of the value of the Fund's total assets in
illiquid securities which may be illiquid due to legal or contractual
restrictions on resale or the absence of readily available market quotations.

          3.  MuniFund and MuniCash only: A Fund may not invest in industrial
              --------------------------                           
revenue bonds where the payment of principal and interest are the responsibility
of a company (including its predecessors) with less than 3 years of continuous
operations.

                ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

IN GENERAL

          Information on how to purchase and redeem each Fund's shares is
included in the applicable Prospectuses.  The issuance of shares is recorded on
a Fund's books, and share certificates are not issued unless expressly requested
in writing. Certificates are not issued for fractional shares.

          The regulations of the Comptroller of the Currency provide that funds
held in a fiduciary capacity by a national bank approved by the Comptroller to
exercise fiduciary powers must be invested in accordance with the instrument
establishing the fiduciary relationship and local law.  The Company believes
that the purchase of shares of the Funds by such national banks acting on behalf
of their fiduciary accounts is not contrary to applicable regulations if
consistent with the particular account and proper under the law governing the
administration of the account.

          Prior to effecting a redemption of shares represented by certificates,
PFPC, the Company's transfer agent, must have received such certificates at its
principal office.  All such certificates must be endorsed by the redeeming
shareholder or accompanied by a signed stock power, in each instance the
signature must be guaranteed.  A signature guarantee may be obtained from a
domestic bank or trust company, broker, dealer, clearing agency or savings
association who are participants in a medallion program recognized by the
Securities Transfer Association.  The three recognized medallion programs are
Securities Transfer Agents Medallion Program (STAMP), Stock Exchanges Medallion
Signature Program (MSP) and the New York Stock Exchange, Inc. Medallion
Securities Program.  Signature guarantees that are not part of 

                                      -40-
<PAGE>
 
these programs will not be accepted. A Fund may require any additional
information reasonably necessary to evidence that a redemption has been duly
authorized.

          Under the 1940 Act, a Fund may suspend the right of redemption or
postpone the date of payment upon redemption for any period during which the New
York Stock Exchange is closed, other than customary weekend and holiday
closings, or during which trading on said Exchange is restricted, or during
which (as determined by the SEC by rule or regulation) an emergency exists as a
result of which disposal or valuation of portfolio securities is not reasonably
practicable, or for such other periods as the SEC may permit. (A Fund may also
suspend or postpone the recordation of the transfer of its shares upon the
occurrence of any of the foregoing conditions.)

          In addition, if, in the opinion of the directors of the Company,
ownership of shares has or may become concentrated to an extent which would
cause a Fund to be deemed a personal holding company, a Fund may compel the
redemption of, reject any order for or refuse to give effect on the books of a
Fund to the transfer of a Fund's shares in an effort to prevent that
consequence. A Fund may also redeem shares involuntarily if such redemption
appears appropriate in light of a Fund's responsibilities under the 1940 Act or
otherwise. If the Company's Board of Directors determines that conditions exist
which make payment of redemption proceeds wholly in cash unwise or undesirable,
a Fund may make payment wholly or partly in securities or other property. In
certain instances, a Fund may redeem shares pro rata from each shareholder of
record without payment of monetary consideration.

          Any institution purchasing shares on behalf of separate accounts will
be required to hold the shares in a single nominee name (a "Master Account").
Institutions investing in more than one of the portfolios, or classes of shares,
must maintain a separate Master Account for each Fund's class of shares.
Institutions may also arrange with PFPC for certain sub-accounting services
(such as purchase, redemption, and dividend recordkeeping).  Sub-accounts may be
established by name or number either when the Master Account is opened or later.

NET ASSET VALUE

          Net asset value per share of each share in a particular Fund is
calculated by adding the value of all portfolio securities and other assets
belonging to a Fund, subtracting the Fund's liabilities, and dividing the result
by the number of outstanding shares in the Fund.  "Assets belonging to" a Fund
consist of the consideration received upon the issuance of Fund shares together
with all income, earnings, profits and proceeds derived from the investment
thereof, including any proceeds from the sale of such investments, any funds or
payments derived from any reinvestment of such proceeds, and a portion of any
general assets not belonging to a particular portfolio.  Assets belonging to a
Fund are charged with the direct liabilities of that Fund and with a share of
the general liabilities of the Company allocated on a daily basis in proportion
to the relative net assets of each of the portfolios.  Determinations made in
good faith and in accordance with generally accepted accounting principles by
the Board of Trustees as to the allocation of any assets or liabilities with
respect to a Fund are conclusive.  The expenses that are charged to a Fund are
borne equally by each share of the Fund, and

                                      -41-

payments to Service Organizations are borne solely by the Dollar Shares, Plus
Shares, Administration Shares, Cash Reserve Shares and Cash Management Shares,
respectively.

          In computing the net asset value of its shares for purposes of sales
and redemptions, each Fund uses the amortized cost method of valuation pursuant
to Rule 2a-7.  Under this method, a Fund values each of its portfolio securities
at cost on the date of purchase and thereafter assumes a constant proportionate
amortization of any discount or premium until maturity of the security.  As a
result, the value of a portfolio security for purposes of determining net asset
value normally does not change in response to fluctuating interest rates.  While
the amortized cost method seems to provide certainty in portfolio valuation, it
may result in valuations of a Fund's securities which are higher or lower than
the market value of such securities.

          In connection with its use of amortized cost valuation, each Fund
limits the dollar-weighted average maturity of its portfolio to not more than 90
days and does not purchase any instrument with a remaining maturity of more than
13 months (with certain exceptions).  The Board of Trustees has also established
procedures, pursuant to rules promulgated by the SEC, that are intended to
stabilize each Fund's net asset value per share for purposes of sales and
redemptions at $1.00.  Such procedures include the determination, at such
intervals as the Board deems appropriate, of the extent, if any, to which a
Fund's net asset value per share calculated by using available market quotations
deviates from $1.00 per share.  In the event such deviation exceeds 1/2 of 1%,
the Board will promptly consider what action, if any, should be initiated.  If
the Board believes that the amount of any deviation from a Fund's $1.00
amortized cost price per share may result in material dilution or other unfair
results to investors or existing shareholders, it will take such steps as it
considers appropriate to eliminate or reduce to the extent reasonably
practicable any such dilution or unfair results.  These steps may include
selling portfolio instruments prior to maturity to realize capital gains or
losses or to shorten a Fund's average portfolio maturity, redeeming shares in
kind, reducing or withholding dividends, or utilizing a net asset value per
share determined by using available market quotations.

1.   A Fund complex means two or more investment companies that hold themselves
     out to investors as related companies for purposes of investment and
     investor services, or have a common investment adviser or have an
     investment adviser that is an affiliated person of the investment adviser
     of any of the other investment companies.

2.   Total number of such other investment companies a trustee served on within
     the Fund Complex.

*    This trustee is considered by the Company to be an "interested person" of
     the Company as defined by the 1940 Act.

          Until January 28, 1999, when the Predecessor Companies were

fees as counsel to the Company. No employee of PDI, BIMC, PFPC or PNC Bank
receives any compensation from the Predecessor Companies for acting as an
officer or director of the Predecessor Companies.  The directors and officers of
the Predecessor Companies as a group own less than 1% of the shares of each of
the Predecessor Funds.

DISTRIBUTOR

                                      -49-
<PAGE>
 
          Provident Distributos, Inc. ("PDI") acts as the distributor of the
Fund's shares. PDI is a Delaware corporation and has its principal business
address at Four Falls Corporate Center, 6th Floor, West Conshohocken,
Pennsylvania 19428. Each Fund's shares are sold on a continuous basis by the
distributor as agent, although it is not obliged to sell any particular amount
of shares. The distributor pays the cost of printing and distributing
prospectuses to persons who are not shareholders of the Funds (excluding
preparation and printing expenses necessary for the continued registration of
the Fund shares). The distributor prepares or reviews, provides advice with
respect to, and files with the federal and state agencies or other organizations
as required by federal, state or other applicable laws and regulations, all
sales literature (advertisements, brochures and shareholder communications) for
each of the Funds and any class or subclass thereof. No compensation is payable
by the Fund to the distributor for its distribution services.

CUSTODIAN AND TRANSFER AGENT

          Pursuant to a Custodian Agreement, PNC Bank, an affiliate of the
Adviser, serves as each Fund's custodian, holding a Fund's portfolio securities,
cash and other property.  PNC Bank has its principal offices at 1600 Market
Street, Philadelphia, PA  19103.  Under the Custodian Agreement, PNC Bank has
agreed to provide the following services:  (i) maintain a separate account or
accounts in the name of a Fund; (ii) hold and disburse portfolio securities on
account of a Fund; (iii) collect and make disbursements of money on behalf of a
Fund; (iv) collect and receive all income and other payments and distributions
on account of a Fund's portfolio securities; and (v) make periodic reports to
the Board of Trustees concerning a Fund's operations.

          PNC Bank is also authorized to select one or more banks or trust
companies to serve as sub-custodian on behalf of a Fund, provided that PNC Bank
shall remain responsible for the performance of all of its duties under the
Custodian Agreement and shall hold each Fund harmless from the acts and
omissions of any bank or trust company serving as sub-custodian chosen by PNC
Bank.

          Under the Custodian Agreement, each Fund pays PNC Bank an annual fee
equal to $.25 for each $1,000 of each Fund's average daily gross assets.  With
respect to TempFund, TempCash, FedFund, T-Fund, Federal Trust Fund, Treasury
Trust Fund, MuniFund and MuniCash, such fee declines as each such Fund's average
daily gross assets increase.  In addition, each Fund pays the custodian certain
types of transaction charges, and reimburses the custodian for out-of-pocket
expenses incurred on behalf of the Fund.

          PFPC also serves as transfer agent, registrar and dividend disbursing
agent to each Fund pursuant to a Transfer Agency Agreement.  Under the
Agreement, PFPC has agreed to provide the following services: (i) maintain a
separate account or accounts in the name of a Fund; (ii) issue, transfer and
redeem Fund shares; (iii) transmit all communications by a Fund to its
shareholders of record, including reports to shareholders, dividend and
distribution notices and proxy material for its meetings of shareholders; (iv)
respond to correspondence by

                                      -50-
<PAGE>
 
shareholders, security brokers and others relating to its duties; (v) maintain
shareholder accounts and sub-accounts; (vi) provide installation and other
services in connection with the Funds' computer access program maintained to
facilitate shareholder access to a Fund; (vii) send each shareholder of record a
monthly statement showing the total number of a Fund's shares owned as of the
last business day of the month (as well as the dividends paid during the current
month and year); and (viii) provide each shareholder of record with a daily
transaction report for each day on which a transaction occurs in the
shareholder's Master Account with a Fund. Further, an institution establishing
sub-accounts with PFPC is provided with a daily transaction report for each day
on which a transaction occurs in a sub-account and, as of the last calendar day
of each month, a report which sets forth the share balances for the sub-accounts
at the beginning and end of the month and income paid or reinvested during the
month. Finally, PFPC provides each shareholder of record with copies of all
information relating to dividends and distributions which is required to be
filed with the Internal Revenue Service and other appropriate taxing
authorities.

          For transfer agency and dividend disbursing services, each Fund pays
PFPC fees at the annual rate of $12.00 per account and sub-account maintained by
PFPC plus $1.00 for each purchase or redemption transaction by an account (other
than a purchase transaction made in connection with the automatic reinvestment
of dividends).  Payments to PFPC for sub-accounting services provided by others
are limited to the amount which PFPC pays to others for such services.  In
addition, each Fund reimburses PNC Bank and PFPC for out-of-pocket expenses
related to such services.

BANKING LAWS

          Banking laws and regulations presently prohibit a bank holding company
registered under the Federal Bank Holding Company Act of 1956 or any bank or
non-bank affiliate thereof from sponsoring, organizing or controlling a
registered, open-end investment company engaged continuously in the issuance of
its shares, and prohibit banks generally from issuing, underwriting, selling or
distributing securities such as Fund shares.  Such banking laws and regulations
do not prohibit such a holding company or affiliate or banks generally from
acting as investment adviser, transfer agent or custodian to such an investment
company, or from purchasing shares of such a company for or upon the order of
customers.

          BIMC, PNC Bank and PFPC believe that they may perform the services for
the Funds contemplated by their respective agreements, Prospectuses and this
Statement of Additional Information without violation of applicable banking laws
or regulations.  It should be noted, however, that future changes in legal
requirements relating to the permissible activities of banks and their
affiliates, as well as further interpretations of present requirements, could
prevent BIMC and PFPC from continuing to perform such services for the Funds.
If BIMC and PFPC were prohibited from continuing to perform such services, it is
expected that the Company's Board of Trustees would recommend that the Funds
enter into new agreements with other qualified firms.  Any new advisory
agreement would be subject to shareholder approval.

                                      -51-

          In addition, state securities laws on this issue may differ from the
interpretations of federal law expressed herein and banks and financial
institutions may be required to register as dealers pursuant to state law.

SERVICE ORGANIZATIONS

          Each of the Funds enter into agreements with institutional investors
("Service Organizations") requiring them to provide support services to their
customers who beneficially own Dollar Shares and, with respect to T-Fund,
MuniFund, TempFund, NY Money Fund and California Money Fund, Plus Shares, in
consideration of .25% (on an annualized basis) of the average daily net asset
value of the Dollar and Plus Shares held by the Service Organizations for the
benefit of their customers.  Such services include:  (i) aggregating and
processing purchase and redemption requests from customers and placing net
purchase and redemption orders with the transfer agent; (ii) providing customers
with a service that invests the assets of their accounts in Dollar or Plus
Shares; (iii) processing dividend payments from the Fund on behalf of customers;
(iv) providing information periodically to customers showing their positions in
Dollar and Plus Shares; (v) arranging for bank wires; (vi) responding to
customer inquiries relating to the services performed by the Service
Organizations; (vii) providing sub-accounting with respect to Dollar and Plus
Shares beneficially owned by customers or the information necessary for sub-
accounting; (viii) forwarding shareholder communications from the Fund (such as
proxies, shareholder reports, annual and semi-annual financial statements and
dividend, distribution and tax notices) to customers, if required by law; and
(ix) other similar services if requested by the Fund.  In addition,
broker/dealers purchasing Plus Shares provide from time to time assistance (such
as the forwarding of sales literature and advertising to customers) in
connection with the distribution of Plus Shares.

          TempFund, T-Fund, MuniFund and California Money Fund may also enter
into agreements with Service Organizations requiring them to provide support
services to their customers who beneficially own Administration Shares, in
consideration of .10% (on an annualized basis) of the average daily net asset
value of the Administration Shares held by the Service Organization for the
benefit of their customers.  Such services include, but are not limited to:  (i)
answering shareholder inquiries regarding account status and history, the manner
in which purchases, exchanges and redemptions of shares may be effected and
certain other matters pertaining to the shareholders' investments; and (ii)
assisting shareholders in designating and changing dividend options, account

          The Fund's agreements with Service Organizations are governed by Plans
(called "Shareholder Services Plan" for the Dollar, Administration, Cash
Reserves and Cash Management Shares and "Distribution and Services Plan" for the
Plus shares), which have been adopted by the Fund's Board of Trustees pursuant
to applicable rules and regulations of the SEC.  Pursuant to the Plans, the
Board of Trustees reviews, at least quarterly, a written report of the amounts
expended under the Fund's agreements with Service Organizations and the purposes
for which the expenditures were made.  In addition, the Fund's arrangements with
Service Organizations must be approved annually by a majority of the Fund's
trustees, including a majority of the trustees who are not "interested persons"
of the Fund as defined in the 1940 Act and have no direct or indirect financial
interest in such arrangements.     
    
          The Board of Trustees have approved the Funds' arrangements with
Service Organizations based on information provided to the Boards that there is
a reasonable likelihood that the arrangements will benefit the Class of Shares
of the Fund charged with such fees and its shareholders.  Any material amendment
to the Funds' arrangements with Service Organizations must be made in a manner
approved by a majority of the Funds' Board of Trustees (including a majority of
the Non-Interested Trustees), and any amendment to increase materially the costs
under the Distribution and Services Plan adopted by the Board with respect to
Plus shares must be approved by the holders of a majority of the outstanding
Plus shares.  (It should be noted that while the annual service fee with respect
to Plus shares is currently set at .25%, the Plans adopted by the Board of
Trustees permits the Board to increase this fee to .40% without shareholder
approval.)  So long as the Funds' arrangements with Service Organizations are in
effect, the selection and nomination of the members of the Funds' Board of
Trustees who are not "interested persons" (as defined in the 1940 Act) of the
Fund will be committed to the discretion of such non-interested directors.     

          The following chart provides information with respect to the fees paid
to Service Organizations, including the amounts paid to affiliates of BIMC
during the fiscal year for each Fund ended in 1996, 1997 and 1998.

EXPENSES
- --------

          A Fund's expenses include taxes, interest, fees and salaries of the
Company's Trustees and officers who are not Trustees, officers or employees of
the Company's service contractors, SEC fees, state securities registration fees,
costs of preparing and printing prospectuses for regulatory purposes and for
distribution to shareholders, advisory and administration fees, charges of the
custodian and of the transfer and dividend disbursing agent, Service
Organization fees, costs of the Funds' computer access program, certain
insurance premiums, outside auditing and legal expenses, costs of shareholder
reports and shareholder meetings and any extraordinary expenses.  A Fund also
pays for brokerage fees and commissions (if any) in connection with the purchase
and sale of portfolio securities.


                    ADDITIONAL INFORMATION CONCERNING TAXES
    
          Each Fund intends to qualify as a regulated investment company under
Subchapter M of the Internal Revenue Code, and to distribute out its income to
shareholders each year, so that each Fund itself will be relieved of federal
income and excise taxes.  If a Fund were to fail to so qualify: (1) the Fund
would be taxed at regular corporate rates without any      

                                      -55-
<PAGE>
 
deduction for distributions to shareholders; and (2) shareholders would be taxed
as if they received ordinary dividends, although corporate shareholders could be
eligible for the dividends received deduction.

          A 4% nondeductible excise tax is imposed on regulated investment
companies that fail currently to distribute an amount equal to specified
percentages of their ordinary taxable income and capital gain net income (excess
of capital gains over capital losses).  Each Fund intends to make sufficient
distributions or deemed distributions of its ordinary taxable income and any
capital gain net income prior to the end of each calendar year to avoid
liability for this excise tax.

          Each Fund will be required in certain cases to withhold and remit to
the U.S. Treasury 31% of taxable dividends or 31% of gross proceeds paid to a
shareholder who has failed to provide a correct tax identification number in the
manner required, is subject to withholding by the Internal Revenue Service for
failure properly to include on his return payments of taxable interest or
dividends, or has failed to certify to the Fund that he is not subject to backup
withholding when required to do so or that it is an "exempt recipient."

          The following is applicable to MuniFund, MuniCash, California Money
Fund and New York Money Fund only:

          As described above and in the Funds' Prospectuses, each Fund is
designed to provide institutions with current tax-exempt interest income.
Neither Fund is intended to constitute a balanced investment program nor is
designed for investors seeking capital appreciation or maximum tax-exempt income
irrespective of fluctuations in principal.  Shares of a Fund would not be
suitable for tax-exempt institutions and may not be suitable for retirement
plans qualified under Section 401 of the Code, H.R. 10 plans and individual
retirement accounts because such plans and accounts are generally tax-exempt
and, therefore, not only would not gain any additional benefit from a Fund's
dividends being tax-exempt but also such dividends would be taxable when
distributed to the beneficiary.  In addition, a Fund may not be an appropriate
investment for entities which are "substantial users" of facilities financed by
private activity bonds or "related persons" thereof.  "Substantial user" is
defined under U.S. Treasury Regulations to include a non-exempt person who
regularly uses a part of such facilities in his or her trade or business and
whose gross revenues derived with respect to the facilities financed by the
issuance of bonds are more than 5% of the total revenues derived by all users of
such facilities, or who occupies more than 5% of the usable area of such
facilities or for whom such facilities or a part thereof were specifically
constructed, reconstructed or acquired.  "Related persons" include certain
related natural persons, affiliated corporations, a partnership and its
partners, and an S Corporation and its shareholders.
    
          In order for a Fund to pay exempt-interest dividends for any taxable
year, at least 50% of the aggregate value of that Fund's assets must consist of
exempt-interest obligations      

                                      -56-

                                   DIVIDENDS

GENERAL
- -------

          Each Fund's net investment income for dividend purposes consists of
(i) interest accrued and original issue discount earned on that Fund's assets,
(ii) plus the amortization of market discount and minus the amortization of
market premium on such assets and (iii) less accrued expenses directly
attributable to that Fund and the general expenses (e.g. legal, accounting and
Trustees' fees) of the Company prorated to such Fund on the basis of its
relative net assets.  Any realized short-term capital gains may also be
distributed as dividends to Fund shareholders.  In addition, a Fund's Dollar
Shares and/or Plus Shares bear exclusively the expense of fees paid to Service
Organizations.  (See "Management of the Funds -- Service Organizations.")

          As stated, the Company uses its best efforts to maintain the net asset
value per share of each Fund at $1.00.  As a result of a significant expense or
realized or unrealized loss incurred by either Fund, it is possible that the
Fund's net asset value per share may fall below $1.00.

    
              ADDITIONAL YIELD AND OTHER PERFORMANCE INFORMATION     

          The "yields" and "effective yields" are calculated separately for each
Fund.  The seven-day yield for each class or sub-class of shares in a Fund is
calculated by determining the net change in the value of a hypothetical pre-
existing account in a Fund having a balance of one share of the class involved
at the beginning of the period, dividing the net change by the value of the
account at the beginning of the period to obtain the base period return, and
multiplying the base period return by 365/7.  The net change in the value of an
account in a Fund includes the value of additional shares purchased with
dividends from the original share and dividends declared on the original share
and any such additional shares, net of all fees charged to all shareholder
accounts in proportion to the length of the base period and the Fund's average
account size, but does not include gains and losses or unrealized appreciation
and depreciation.  In addition, the effective annualized yield may be computed
on a compounded basis (calculated as described above) by adding 1 to the base
period return, raising the sum to a power equal to 365/7, and subtracting 1 from
the result.  Similarly, based on the calculations described above, 30-day (or
one-month) yields and effective yields may also be calculated.

          From time to time, in reports to shareholders or otherwise, a Fund's
yield or total return may be quoted and compared to that of other money market
funds or accounts with similar investment objectives, to stock or other relevant
indices and to other reports or analyses that relate to yields, interest rates,
total return, market performance, etc.  For example, the yield of the Fund may
be compared to the IBC/Donoghue's Money Fund Average, which is an average
                                  ----- ---- -------                     
compiled by IBC/Donoghue's MONEY FUND REPORT(R) of Holliston, MA  01746, a
widely recognized independent publication that monitors the performance of money
market funds, or to the average yields reported by the Bank Rate Monitor from
                                                       ---- ---- -------     
money market deposit accounts offered by the 50 leading banks and thrift
institutions in the top five standard metropolitan statistical areas.     
    
          YIELD AND RETURN WILL FLUCTUATE, AND ANY QUOTATION OF YIELD OR RETURN
SHOULD NOT BE CONSIDERED AS REPRESENTATIVE OF THE FUTURE PERFORMANCE OF THE
FUND.  Since yields and returns fluctuate, performance data cannot necessarily
be used to compare an investment in a Fund's shares with bank deposits, savings
accounts, and similar investment alternatives which often provide an agreed or
guaranteed fixed yield for a stated period of time.  Shareholders should
remember that performance and yield are generally functions of the kind and
quality of the investments held in a fund, portfolio maturity, operating
expenses and market conditions.  Any fees charged by banks with respect to
customer accounts in investing in shares of a Fund will not be included in yield
or return calculations; such fees, if charged, would reduce the actual yield or
return from that quoted.     

          The Funds may also from time to time include in advertisements, sales
literature, communications to shareholders and other materials ("Materials"),
discussions or illustrations of the effects of compounding.  "Compounding"
refers to the fact that, if dividends or other distributions on an investment
are reinvested by being paid in additional Portfolio shares, any future income
or capital appreciation of a Fund would increase the value, not only of the
original investment, but also of the additional shares received through
reinvestment.  As a result, the value of the Fund investment would increase more
quickly than if dividends or other distributions had been paid in cash.

          In addition, the Funds may also include in Materials discussions
and/or illustrations of the potential investment goals of a prospective investor
(including materials that describe general principles of investing,
questionnaires designed to help create a personal financial profile, worksheets
used to project savings needs based on certain assumptions and action plans
offering investment alternatives), investment management strategies, techniques,
policies or investment suitability of a Fund, economic and political conditions,
the relationship between sectors of the economy and the economy as a whole,
various securities markets, the effects of inflation and historical performance
of various asset classes, including but not limited to, stocks, bonds and
Treasury securities, and hypothetical investment returns based on certain
assumptions.  From time to time, Materials may summarize the substance of
information contained in shareholder reports (including the investment
composition of a Fund), as well as the views of the advisers as to current
market, economic, trade and interest rate trends, legislative, regulatory and
monetary developments, investment strategies and related matters believed to be
of relevance to a Fund.  In addition, selected indices may be used to illustrate
historical 

                                      -59-
<PAGE>
 
performance of select asset classes. The Funds may also include in Materials
charts, graphs or drawings which compare the investment objective, return
potential, relative stability and/or growth possibilities of the Funds and/or
other mutual funds, or illustrate the potential risks and rewards of investment
in various investment vehicles, including but not limited to, stocks, bonds,
Treasury securities and shares of a Fund and/or other mutual funds. Materials
may include a discussion of certain attributes or benefits to be derived by an
investment in a Fund and/or other mutual funds (such as value investing, market
timing, dollar cost averaging, asset allocation, constant ratio transfer,
automatic accounting rebalancing and the advantages and disadvantages of
investing in tax-deferred and taxable investments), shareholder profiles and
hypothetical investor scenarios, timely information on financial management, tax
and retirement planning and investment alternatives to certificates of deposit
and other financial instruments, designations assigned a Fund by various rating
or ranking organizations, and Fund identifiers (such as CUSIP numbers or NASDAQ
symbols). Such Materials may include symbols, headlines or other material which
highlight or summarize the information discussed in more detail therein.

          Materials may include lists of representative clients of the Funds'
investment adviser, may include discussions of other products or services, may
contain information regarding average weighted maturity or other maturity
characteristics, and may contain information regarding the background,
expertise, etc. of the investment adviser or of a Fund's portfolio manager.

          From time to time in advertisements, sales literature and
communications to shareholders, the Funds may compare their total returns to
rankings prepared by independent services or other financial or industry
publications that monitor the performance of mutual funds.  For example, such
data is found in IBC/Donoghue's Money Fund Report and reports prepared by Lipper
Analytical Services, Inc.  Total return is the change in value of an investment
in a Fund over a particular period, assuming that all distributions have been
reinvested.  SUCH RANKINGS REPRESENT THE FUNDS' PAST PERFORMANCE AND SHOULD NOT
BE CONSIDERED AS REPRESENTATIVE OF FUTURE RESULTS.

          The following information has been provided by the Funds' distributor:
In managing each Fund's portfolio, the investment adviser utilizes a "pure and
simple" approach, which may include disciplined research, stringent credit
standards and careful management of maturities.

                   ADDITIONAL DESCRIPTION CONCERNING SHARES
                                        
          The Company was organized as a Delaware business trust on October 21,
1998.  The Company's Declaration of Trust authorizes the Board of Trustees to
issue an unlimited number of full and fractional shares of beneficial interest
in the Company and to classify or reclassify any unissued shares into one or
more series of shares.  Pursuant to such authority, the Board of Trustees has
authorized the issuance of ten series of shares designated as TempFund,
TempCash, FedFund, T-Fund, Federal Trust Fund, Treasury Trust Fund, MuniFund,
MuniCash, California Money Fund and New York Money Fund.  The Declaration of
Trust further authorizes the trustees to classify or reclassify any series of
shares into one or more classes.  Currently, the classes authorized are Dollar,
Plus, Administration, Cash Reserves and Cash Management.

          The Company does not presently intend to hold annual meetings of
shareholders except as required by the 1940 Act or other applicable law.  Upon
the written request of shareholders owning at least 25% of the Company's shares,
the Company will call for a meeting of shareholders to consider the removal of
one or more Trustees and other certain matters.  To the extent required by law,
the Company will assist in shareholder communication in such matters.

          Holders of shares in a Fund in the Company will vote in the aggregate
and not by class or sub-class on all matters, except as described above, and
except that Fund's Dollar Plus, Administration, Cash Reserves and Cash
Management Shares, as described in "Service Organizations" above, shall be
entitled to vote on matters submitted to a vote of shareholders pertaining to
that Fund's arrangements with its Service Organizations.  Further, shareholders
of each of the Company's portfolios will vote in the aggregate and not by
portfolio except as otherwise required by law or when the Board of Trustees
determines that the matter to be voted upon affects only the interests of the
shareholders of a particular portfolio.  Rule 18f-2 under the 1940 Act provides
that any matter required to be submitted by the provisions of such Act or
applicable state law, or otherwise, to the holders of the outstanding securities
of an investment company such as the Company shall not be deemed to have been
effectively acted upon unless approved by the holders of a majority of the
outstanding shares of each portfolio affected by the matter.  Rule 18f-2 further
provides that a portfolio shall be deemed to be affected by a matter unless it
is clear that the interests of each portfolio in the matter are identical or
that the matter does not affect any interest of the portfolio.  Under the Rule,
the approval of an investment advisory agreement or any change in a fundamental
investment policy would be effectively acted upon with respect to a portfolio
only if approved by the holders of a majority of the outstanding voting
securities of such portfolio.  However, the Rule also provides that the
ratification of the selection of independent accountants, the approval of
principal underwriting contracts, and the election of Trustees are not subject
to the separate voting requirements and may be effectively acted upon by
shareholders of the investment company voting without regard to portfolio.

          Notwithstanding any provision of Delaware law requiring a greater vote
of shares of the Company's Common Stock (or of any class voting as a class) in
connection with any corporate action, unless otherwise provided by law (for
example by Rule 18f-2 discussed above) 

                                      -61-
<PAGE>
 
or by the Company's Charter, the Company may take or authorize such action upon
the favorable vote of the holders of more than 50% of all of the outstanding
shares of Common Stock voting without regard to class (or portfolio).

                                  ----------

COMMERCIAL PAPER RATINGS
- ------------------------

          A Standard & Poor's ("S&P") commercial paper rating is a current
assessment of the likelihood of timely payment of debt having an original
maturity of no more than 365 days. The following summarizes the applicable
rating categories used by Standard and Poor's for commercial paper:

          "A-1" - Obligations are rated in the highest category indicating that
the obligor's capacity to meet its financial commitment on the obligation is
strong. Within this category, certain obligations are designated with a plus
sign (+). This indicates that the obligor's capacity to meet its financial
commitment on these obligations is extremely strong.

          "A-2" - Obligations are somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rating categories. However, the obligor's capacity to meet its financial
commitment on the obligation is satisfactory.

          Moody's commercial paper ratings are opinions of the ability of
issuers to repay punctually senior debt obligations not having an original
maturity in excess of one year, unless explicitly noted. The following
summarizes the applicable rating categories used by Moody's for commercial
paper:

          "Prime-1" - Issuers (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:
leading market positions in well-established industries; high rates of return on
funds employed; conservative capitalization structure with moderate reliance on
debt and ample asset protection; broad margins in earnings coverage of fixed
financial charges and high internal cash generation; and well-established access
to a range of financial markets and assured sources of alternate liquidity.

          "Prime-2" - Issuers (or supporting institutions) have a strong ability
for repayment of senior short-term debt obligations. This will normally be
evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

          The applicable rating categories of Duff & Phelps for commercial paper
and short-term debt are "D-1" and "D-2." Duff & Phelps employs three
designations, "D-1+," "D-1" and "D-1-," within the highest rating category. The
following summarizes the rating categories used by Duff & Phelps for commercial
paper:

                                      A-1
<PAGE>
 
          "D-1+" - Debt possesses the highest certainty of timely payment. 
Short-term liquidity, including internal operating factors and/or access to
alternative sources of funds, is outstanding, and safety is just below risk-free
U.S. Treasury short-term obligations.

          "D-1" - Debt possesses very high certainty of timely payment.
Liquidity factors are excellent and supported by good fundamental protection
factors. Risk factors are minor.

          "D-1-" - Debt possesses high certainty of timely payment. Liquidity
factors are strong and supported by good fundamental protection factors. Risk
factors are very small.

          "D-2" - Debt possesses good certainty of timely payment. Liquidity
factors and company fundamentals are sound. Although ongoing funding needs may
enlarge total financing requirements, access to capital markets is good. Risk
factors are small.

          Thomson BankWatch short-term ratings assess the likelihood of an
untimely payment of principal and interest of debt instruments with original
maturities of one year or less. The following summarizes the applicable ratings
used by Thomson BankWatch:

          "TBW-1" - This designation represents Thomson BankWatch's highest
category and indicates a very high likelihood that principal and interest will
be paid on a timely basis.

          "TBW-2" - This designation represents Thomson BankWatch's second-
highest category and indicates that while the degree of safety regarding timely
repayment of principal and interest is strong, the relative degree of safety is
not as high as for issues rated "TBW-1."

CORPORATE AND MUNICIPAL LONG-TERM DEBT RATINGS
- ----------------------------------------------

          The following summarizes the applicable ratings used by Standard &
Poor's for corporate and municipal debt:

          "AAA" - An obligation rated "AAA" has the highest rating assigned by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is extremely strong.

          "AA" - An obligation rated "AA" differs from the highest rated
obligations only in small degree. The obligor's capacity to meet its financial
commitment on the obligation is very strong.

          PLUS (+) OR MINUS (-) - The rating "AA" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.

          The following summarizes the applicable ratings used by Moody's for
corporate and municipal long-term debt:

                                      A-2
<PAGE>
 
          "Aaa" - Bonds are judged to be of the best quality. They carry the
smallest degree of investment risk and are generally referred to as "gilt
edged." Interest payments are protected by a large or by an exceptionally stable
margin and principal is secure. While the various protective elements are likely
to change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues.

          "Aa" - Bonds are judged to be of high quality by all standards.
Together with the "Aaa" group they comprise what are generally known as high-
grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in "Aaa" securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risk appear somewhat larger than the "Aaa"
securities.

          Note: Moody's applies numerical modifiers 1, 2, and 3 in the generic
rating classification "Aa". The modifier 1 indicates that the obligation ranks
in the higher end of its generic rating category; the modifier 2 indicates a 
mid-range ranking; and the modifier 3 indicates a ranking in the lower end of
its generic rating category.

          The following summarizes the long-term debt ratings used by Duff &
Phelps for corporate and municipal long-term debt:

          "AAA" - Debt is considered to be of the highest credit quality. The
risk factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.

          "AA" - Debt is considered to be of high credit quality. Protection
factors are strong. Risk is modest but may vary slightly from time to time
because of economic conditions.

          To provide more detailed indications of credit quality, the "AA," and
"A," ratings may be modified by the addition of a plus (+) or minus (-) sign to
show relative standing within these major categories.

          The following summarizes the applicable ratings used by Fitch IBCA for
corporate and municipal bonds:

          "AAA" - Bonds considered to be investment grade and of the highest
credit quality. These ratings denote the lowest expectation of credit risk and
are assigned only in case of exceptionally strong capacity for timely payment of
financial commitments. This capacity is highly unlikely to be adversely affected
by foreseeable events.

          "AA" - Bonds considered to be investment grade and of very high credit
quality. These ratings denote a very low expectation of credit risk and indicate
very strong capacity for timely payment of financial commitments. This capacity
is not significantly vulnerable to foreseeable events.

                                      A-3
<PAGE>
 
          To provide more detailed indications of credit quality, the Fitch IBCA
ratings "AA" may be modified by the addition of a plus (+) or minus (-) sign to
show relative standing within these major rating categories.

          Thomson BankWatch assesses the likelihood of an untimely repayment of
principal or interest over the term to maturity of long term debt and preferred
stock which are issued by United States commercial banks, thrifts and non-bank
banks; non-United States banks; and broker-dealers.  The following summarizes
the rating categories used by Thomson BankWatch for long-term debt ratings:

          "AAA" - This designation indicates that the ability to repay principal
and interest on a timely basis is extremely high.

          "AA" - This designation indicates a very strong ability to repay
principal and interest on a timely basis, with limited incremental risk compared
to issues rated in the highest category.

          PLUS (+) OR MINUS (-) - The ratings may include a plus or minus sign
designation which indicates where within the respective category the issue is
placed.

MUNICIPAL NOTE RATINGS
- ----------------------

          A Standard and Poor's rating reflects the liquidity concerns and
market access risks unique to notes due in three years or less. The following
summarizes the ratings used by Standard & Poor's Ratings Group for municipal
notes:

          "SP-1" - The issuers of these municipal notes exhibit a strong
capacity to pay principal and interest. Those issues determined to possess very
strong characteristics are given a plus (+) designation.

          "SP-2" - The issuers of these municipal notes exhibit satisfactory
capacity to pay principal and interest, with some vulnerability to adverse
financial and economic changes over the term of the notes.

          Moody's ratings for state and municipal notes and other short-term
loans are designated Moody's Investment Grade ("MIG") and variable rate demand
obligations are designated Variable Moody's Investment Grade ("VMIG"). Such
ratings recognize the differences between short-term credit risk and long-term
risk. The following summarizes the ratings by Moody's Investors Service, Inc.
for short-term notes:

          "MIG-1"/"VMIG-1" - This designation denotes best quality. There is
present strong protection by established cash flows, superior liquidity support
or demonstrated broad-based access to the market for refinancing.

                                      A-4
<PAGE>
 
          "MIG-2"/"VMIG-2" - This designation denotes high quality, with margins
of protection that are ample although not so large as in the preceding group.

          Fitch IBCA and Duff & Phelps use the short-term ratings described
under Commercial Paper Ratings for municipal notes.

ITEM 24.  PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT

          Registrant is controlled by its Board of Trustees.

ITEM 25.  INDEMNIFICATION

          Indemnification of Registrant's Co-Administrators, Principal
          Underwriter, Custodian and Transfer Agent against certain stated
          liabilities is provided for in Section 11 of the Co-Administration
          Agreement, Section 5 of the Distribution Agreement, Section 12 of the
          Custodian Services Agreement and Section 12 of the Transfer Agency
          Agreement, respectively, which Agreements are included herewith.

          Registrant has obtained from a major insurance carrier a directors'
          and officers' liability policy covering certain types of errors and
          omissions.

          Article VIII of Registrant's Agreement and Declaration of Trust,
          included herewith, provides for the indemnification of Registrant's
          trustees and officers.

                                      -2-
<PAGE>
 
          Insofar as indemnification for liability arising under the Securities
          Act of 1933 may be permitted to directors, officers, and controlling
          persons of Registrant pursuant to the foregoing provisions, or
          otherwise, Registrant has been advised that in the opinion of the SEC
          such indemnification is against public policy as expressed in the Act
          and is, therefore, unenforceable.  In the event that a claim for
          indemnification against such liabilities (other than the payment by
          Registrant of expenses incurred or paid by a director, officer or
          controlling person of Registrant in the successful defense of any
          action, suit or proceeding) is asserted by such director, officer or
          controlling person in connection with the securities being registered,
          Registrant will, unless in the opinion of its counsel the matter has
          been settled by controlling precedent, submit to a court of
          appropriate jurisdiction the question whether such indemnification by
          it is against public policy as expressed in the Act and will be
          governed by the final adjudication of such issue.

ITEM 26.  BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER

          BIMC performs investment advisory services for Registrant and certain
          other investment companies and accounts.  The information required by

                                   ----------

                              BENEFICIAL INTEREST

  Section 2.1  Shares of Beneficial Interest.  The beneficial interest in the
               -----------------------------                                 
Trust shall be divided into such transferable Shares of one or more separate and
distinct Series and Classes within a Series as the Trustees shall from time to
time create and establish.  The number of Shares of each Series and Class
authorized hereunder is unlimited.  Each Share shall have no par value, unless
otherwise determined by the Trustees in connection with the creation and
establishment of a Series or Class.  All Shares issued hereunder, including
without limitation, 

                                      -2-
<PAGE>
 
Class Shares issued in connection with a dividend in Shares or a split or
reverse split of Shares, shall be fully paid and nonassessable.

  Section 2.2  Issuance of Shares.  The Trustees in their discretion may, from
               ------------------                                             
time to time, without vote of the Shareholders, issue Shares of each Series and
Class to such party or parties and for such amount and type of consideration (or
for no consideration if pursuant to a Share dividend or split-up), subject to
applicable law, including cash or securities (including Shares of a different
Series or Class), at such time or times and on such terms as the Trustees may
deem appropriate, and may in such manner acquire other assets (including the
acquisitions of assets subject to, and in connection with, the assumption of
liabilities) and businesses.  In connection with any issuance of Shares, the
Trustees may issue fractional Shares and Shares held in the treasury.  The
Trustees may from time to time divide or combine the Shares into a greater or
lesser number without thereby changing the proportionate beneficial interests in
the Trust.  The Trustees may classify or reclassify any unissued Shares or any
Shares previously issued and reacquired of any Series or Class into one or more
Series or Classes that may be established and designated from time to time.

          Any Trustee, officer or other agent of the Trust, and any organization
in which any such person is interested, may acquire, own, hold and dispose of
Shares of any Series or Class of the Trust to the same extent as if such person
were not a Trustee, officer or other agent of the Trust; and the Trust may issue
and sell or cause to be issued and sold and may purchase Shares of any Series or
Class from any such person or any such organization subject only to the general
limitations, restrictions or other provisions applicable to the sale or purchase
of Shares of such Series or Class generally.

  Section 2.3  Register of Shares and Share Certificates.  A  register shall be
               -----------------------------------------                       
kept at the principal office of the Trust or an office of the Trust's transfer
agent which shall contain the names and addresses of the Shareholders of each
Series and Class, the number of Shares of that Series and Class thereof held by
them respectively and a record of all transfers thereof.  As to Shares for which
no certificate has been issued, such register shall be conclusive as to who are
the holders of the Shares and who shall be entitled to receive dividends or
other distributions or otherwise to exercise or enjoy the rights of
Shareholders.  No Shareholder shall be entitled to receive payment of any
dividend or other distribution, nor to have notice given to him as herein or in
the By-laws provided, until he has given his address to the transfer agent or
such other officer or agent of the Trust as shall keep the said register for
entry thereon.  The Trustees, in their discretion, may authorize the issuance of
share certificates and promulgate appropriate rules and regulations as to their
use.  In the event that one or more certificates are issued, whether in the name
of a Shareholder or a nominee, such certificate or certificates shall constitute
evidence of ownership of Shares for all purposes, including transfer, assignment
or sale of such Shares, subject to such limitations as the Trustees may, in
their discretion, prescribe.

  Section 2.4  Transfer of Shares.  Except as otherwise provided by the
               ------------------                                      
Trustees, Shares shall be transferable on the records of the Trust only by the
record holder thereof or by his agent thereunto duly authorized in writing, upon
delivery to the Trustees or the Trust's 

                                      -3-
<PAGE>
 
transfer agent of a duly executed instrument of transfer, together with a Share
certificate, if one is outstanding, and such evidence of the genuineness of each
such execution and authorization and of such other matters as may be required by
the Trustees. Upon such delivery the transfer shall be recorded on the register
of the Trust. Until such record is made, the Shareholder of record shall be
deemed to be the holder of such Shares for all purposes hereunder and neither
the Trustees nor the Trust, nor any transfer agent or registrar nor any officer,
employee or agent of the Trust shall be affected by any notice of the proposed
transfer.

  Section 2.5  Treasury Shares.  Shares held in the treasury shall, until
               ---------------                                           
reissued pursuant to Section 2.2 hereof, not confer any voting rights on the
Trustees, nor shall such Shares be entitled to any dividends or other
distributions declared with respect to the Shares.

  Section 2.6  Establishment of Series and Classes.  The Trust shall consist of
               -----------------------------------                             
one or more Series and Classes and separate and distinct records shall be
maintained by the Trust for each Series and Class.  The Trustees shall have full
power and authority, in their sole discretion, and without obtaining any prior
authorization or vote of the Shareholders of any Series or Class of the Trust,
to establish and designate and to change in any manner any initial or additional
Series or Classes and to fix such preferences, voting powers, rights and
privileges of such Series or Classes as the Trustees may from time to time
determine, to divide or combine the Shares or any Series or Classes into a
greater or lesser number, to classify or reclassify any issued Shares or any
Series or Classes into one or more Series or Classes of Shares, and to take such
other action with respect to the Shares as the Trustees may deem desirable.
Unless another time is specified by the Trustees, the establishment and
designation of any Series or Class shall be effective upon the adoption of a
resolution by the Trustees setting forth such establishment and designation and
the preferences, powers, rights and privileges of the Shares of such Series or
Class, whether directly in such resolution or by reference to, or approval of,
another document that sets forth such relative rights and preferences of such
Series (or Class) including, without limitation, any registration statemet of
the Trust, or as otherwise provided in such resolution.  The Trust may issue any
number of Shares of each Series or Class and need not issue certificates for any
Shares.

     All references to Shares in this Trust Instrument shall be deemed to be
Shares of any or all Series or Classes as the context may require.  All
provisions herein relating to the Trust shall apply equally to each Series and
Class of the Trust except as the context otherwise requires.

     All Shares of each Class of a particular Series shall represent an equal
proportionate interest in the assets belonging to that Series (subject to the
liabilities belonging to the Series, and, in the case of each Class, to the
liabilities belonging to that Class), and each Share of any Class of a
particular Series shall be equal to each other Share of that Class; but the
provisions of this sentence shall not restrict any distinctions permissible
under this Section 2.6.

  Section 2.7  Investment in the Trust.  The Trustees shall accept investments
               -----------------------                                        
in any Series of the Trust or Class, if the Series has been divided into
Classes, from such persons and on such terms as they may from time to time
authorize.  At the Trustees' discretion, such investments, subject to applicable
law, may be in the form of cash or securities in which the affected Series is
authorized to invest, valued as provided in Section 7.4 hereof.  Unless the
Trustees otherwise determine, investments in a Series shall be credited to each
Shareholder's account in the form of full Shares at the Net Asset Value per
Share next determined after the investment is received.  Without limiting the
generality of the foregoing, the Trustees may, in their sole discretion, (a) fix
the Net Asset Value per Share of the initial capital contribution, (b) impose
sales or other charges upon investments in the Trust or (c) issue fractional
Shares.

  Section 2.8  Assets and Liabilities Belonging to Series, etc.  All
               ------------------------------------------------     
consideration received by the Trust for the issue or sale of Shares of a
particular Series, together with all assets in which such consideration is
invested or reinvested, all income, earnings, profits, and proceeds thereof,
including any proceeds derived from the sale, exchange or liquidation of such
assets, and any funds or payments derived from any reinvestment of such proceeds
in whatever form the same may be, shall be held and accounted for separately
from the other assets of the Trust and of every other Series and may be referred
to herein as "assets belonging to" that Series.  The assets belonging to a
particular Series shall belong to that Series for all purposes, and to no other
Series, subject only to the rights of creditors of that Series.  In addition,
any assets, income, earnings, profits or funds, or payments and proceeds with
respect thereto, which are not readily identifiable as belonging to any
particular Series shall be allocated by the Trustees between and among one or
more of the Series in such manner as the Trustees, in their sole discretion,
deem fair and equitable.  If there are classes of Shares within a Series, the
assets belonging to the Series shall be further allocated to each Class in the
proportion that the "assets belonging to" the Class (calculated in the same
manner as with determination of assets "belonging to" the Series) bears to the
assets of all Classes within the Series.  Each such allocation shall be
conclusive and binding upon the Shareholders of all Series and Classes for all
purposes, and such assets, income, earnings, profits or funds, or payments and
proceeds with respect thereto shall be assets belonging to that Series or Class,
as the case may be.  The assets belonging to a particular Series and Class shall
be so recorded upon the books of the Trust, and shall be held by the Trustees in
trust for the benefit of the holders of Shares of that Series or Class, as the
case may be.

          The assets belonging to each Series shall be charged with the
liabilities of that Series and all expenses, costs, charges and reserves
attributable to that Series.  Any general liabilities, expenses, costs, charges
or reserves of the Trust which are not readily identifiable as belonging to any
particular Series shall be allocated and charged by the Trustees between or
among any one or more of the Series in such manner as the Trustees in their sole
discretion deem fair and equitable.  Each such allocation shall be conclusive
and binding upon the Shareholders of all Series for all purposes.  The
liabilities, expenses, costs, charges and reserves allocated and so charged to a
Series are herein referred to as "liabilities belonging to" that Series.  Except
as provided in the next sentence or otherwise required or permitted by
applicable law or any rule or order of the Commission, the "liabilities
belonging to" such 

                                      -5-
<PAGE>
 
Series shall be allocated to each Class of a Series in the proportion that the
assets belonging to such Class bear to the assets belonging to all Classes in
the Series. To the extent permitted by rule or order of the Commission, the
Trustees may allocate all or a portion of any liabilities belonging to a Series
to a particular Class or Classes (collectively, "Class Expenses") as the
Trustees may from time to time determine is appropriate. In addition, all
liabilities, expenses, costs, charges and reserves belonging to a Class shall be
allocated to such Class.

     Without limitation of the foregoing provisions of this Section 2.8, but
subject to the right of the Trustees in their discretion to allocate general
liabilities, expenses, costs, charges or reserves as herein provided, the debts,
liabilities, obligations and expenses incurred, contracted for or otherwise
existing with respect to a particular Series shall be enforceable against the
assets belonging to such Series only, and not against the assets of the Trust
generally or any other Series.  Notice of this limitation on inter-Series
liabilities shall be set forth in the certificate of trust of the Trust (whether
originally or by amendment) as filed or to be filed in the Office of the
Secretary of State of the State of Delaware pursuant to the Act, and upon the
giving of such notice in the certificate of trust, the statutory provisions of
Section 3804 of the Act relating to limitations on inter-Series liabilities (and
the statutory effect under Section 3804 of setting forth such notice in the
certificate of trust) shall become applicable to the Trust and each Series.  Any
person extending credit to, contracting with or having any claim against any
Series may satisfy or enforce any debt, liability, obligation or expense
incurred, contracted for or otherwise existing with respect to that Series from
the assets of that Series only.  No Shareholder or former Shareholder of any
Series shall have a claim on or any right to any assets allocated or belonging
to any other Series.

     Similarly, the debts, liabilities, obligations and expenses incurred,
contracted for or otherwise existing with respect to a particular Class shall be
enforceable against the assets belonging to such Class only, and not against the
assets of the Series or the Trust generally or any other Class.  Each contract
entered into by the Trust which is or may be an obligation of a Class within a
Series shall contain a provision to the effect that the parties to the contract
will look only to the assets belonging to the Class for the satisfaction of any
liability, and not to any extent to the assets of any other Class or Series or
the Trust generally.  If, notwithstanding the preceding sentence, any liability
properly charged to a Class is paid from the assets of another Class, the Class
from whose assets the liability was paid shall be reimbursed from the assets of
the Class to which such liability belonged.

  Section 2.9  No Preemptive Rights.  Shareholders shall have no preemptive or
               --------------------                                           
other similar rights to subscribe to any additional Shares or other securities
issued by the Trust or the Trustees, whether of the same or another Series or
Class.

  Section 2.10  Conversion Rights.  The Trustees shall have the authority to
                -----------------                                           
provide from time to time that the holders of Shares of any Series or Class
shall have the right to convert or exchange said Shares for or into Shares of
one or more other Series or Classes in accordance with such requirements and
procedures as may be established from time to time by the Trustees.

  Section 2.11  Legal Proceedings.  No person, other than a Trustee, who is not
                -----------------                                              
a Shareholder of a particular Series or Class shall be entitled to bring any
derivative action, suit or other proceeding on behalf of or with respect to such
Series or Class.  No Shareholder of a Series or a Class may maintain a
derivative action with respect to such Series or Class unless holders of a least
ten percent (10%) of the outstanding Shares of such Series or Class join in the
bringing of such action.  Except as otherwise provided in Section 3816 of the
Act and the foregoing provisions of this Section 2.11, all matters relating to
the bringing of derivative actions in the right of the Trust shall be governed
by the General Corporation Law of the State of  Delaware relating to derivative
actions, and judicial interpretations thereunder, as if the Trust were a
Delaware Corporation and the Shareholders were shareholders of a Delaware
corporation.

     In addition to the requirements set forth in Section 3816 of the Act, a
Shareholder may bring a derivative action on behalf of the Trust with respect to
a Series or Class only if the following conditions are met:  (a) the Shareholder
or Shareholders must make a pre-suit demand upon the Trustees to bring the
subject action unless an effort to cause the Trustees to bring such an action is
not likely to succeed; and a demand on the Trustees shall only be deemed not
likely to succeed and therefore excused if a majority of the Trustees, or a
majority of any committee established to consider the merits of such action, has
a personal financial interest in the transaction at issue, and a Trustee shall
not be deemed interested in a transaction or otherwise disqualified from ruling
on the merits of a Shareholder demand by virtue of the fact that such Trustee
receives remuneration for his service as a Trustee of the Trust or as a trustee
or director of one or more investment companies that are under common management
with or otherwise affiliated with the Trust; and (b) unless a demand is not
required under clause (a) of this paragraph, the Trustees must be afforded a
reasonable amount of time to consider such shareholder request and to
investigate the basis of such claim; and the Trustees shall be entitled to
retain counsel or other advisors in considering the merits of the request and
shall require an undertaking by the Shareholders making such request to
reimburse the Trust for the expense of any such advisors in the event that the
Trustees determine not to bring such action.  For purposes of this Section 2.11,
the Trustees may designate a committee of one Trustee to consider a Shareholder
demand if necessary to create a committee with a majority of Trustees who do not
have a personal financial interest in the transaction at issue.

  Section 2.12  Status of Shares.  Shares shall be deemed to be personal
                ----------------                                        
property giving only the rights provided in this instrument.  Every Shareholder
by virtue of having become a Shareholder shall be held to have expressly
assented and agreed to the terms hereof.  The death of a Shareholder during the
continuance of the Trust shall not operate to terminate the Trust nor entitle
the representative of any deceased Shareholder to an accounting or to take any
action in court or elsewhere against the Trust or the Trustees, but only to the
rights of said decedent under this Trust.  Ownership of Shares shall not entitle
the Shareholder to any title in or to the whole or any part of the Trust
property or right to call for a partition or division of the same or for an
accounting, nor shall the ownership of Shares constitute the Shareholders
partners.

absolute control over the Trust Property and over the business of the Trust to
the same extent as if the Trustees were the sole owners of the Trust Property
and business in their own right, but with such powers of delegation as may be
permitted by this Trust Instrument.  The Trustees shall have power to conduct
the business of the Trust and carry on its operations in any and all of its
branches and maintain offices both within and without the State of Delaware, in
any and all states of the United States of America, in the District of Columbia,
in any and all commonwealths, territories, dependencies, colonies, or
possessions of the United States of America, and in any foreign jurisdiction and
to do all such other things and execute all such instruments as they deem
necessary, proper or desirable in order to promote the interests of the Trust
although such things are not herein specifically mentioned.  Any determination
as to what is in the interests of the Trust made by the Trustees in good faith
shall be conclusive.  In construing the provisions of this Trust Instrument, the
presumption shall be in favor of a grant of power to the Trustees.

     The enumeration of any specific power in this Trust Instrument shall not be
construed as limiting the aforesaid power.  The powers of the Trustees may be
exercised without order of or resort to any court.

     Except for the Trustees named herein or appointed pursuant to Section 3.8,
or Trustees appointed to fill vacancies pursuant to Section 3.3 hereof, the
Trustees shall be elected by the Shareholders owning of record a plurality of
the Shares voting at a meeting of Shareholders.  The initial Trustee of the
Trust shall be Rodney Johnson.

  Section 3.2  Term of Office of Trustees.  Each Trustee shall hold office
               --------------------------                                 
during the existence of this Trust, and until its termination as herein
provided; except: (a) that any Trustee may resign his trust by written
instrument signed by him and delivered to the Chairman, President, Secretary, or
other Trustee of the Trust, which shall take effect upon such delivery or upon
such later date as is specified therein; (b) that any Trustee may be removed at
any time by written instrument, signed by at least two-thirds of the number of
Trustees prior to such removal, specifying the date when such removal shall
become effective; (c) that any Trustee who requests in writing to be retired or
who has died, become physically or mentally incapacitated by reason of disease
or otherwise, or is otherwise unable to serve, may be retired by written
instrument signed by a majority of the other Trustees, specifying the date of
his retirement; and (d) that a Trustee may be removed at any meeting of the
Shareholders of the Trust by a vote of Shareholders owning at least two-thirds
of the outstanding Shares of all Series.

  Section 3.3  Vacancies and Appointment of Trustees.  In case of the
               -------------------------------------

of Trustees shall occur, until such vacancy is filled, the other Trustees shall
have all the powers hereunder and the certificate of the other Trustees of such
vacancy shall be conclusive. In the case of an existing vacancy, the remaining
Trustee or Trustees shall fill such vacancy by appointing such other person as
such Trustee or Trustees in their discretion shall see fit consistent with the
limitations under the 1940 Act, unless such Trustee or Trustees determine, in
accordance with Section 3.5, to decrease the size of the Board to the number of
remaining Trustees.

     An appointment of a Trustee may be made by the Trustees then in office in
anticipation of a vacancy to occur by reason of retirement, resignation or
increase in number of Trustees effective at a later date, provided that said
appointment shall become effective only at or after the effective date of said
retirement, resignation or increase in number of Trustees.

     An appointment of a Trustee shall be effective upon the acceptance of the
person so appointed to serve as trustee, except that any such appointment in
anticipation of a vacancy shall become effective at or after the date such
vacancy occurs.

attorney, delegate his power for a period not exceeding six months at any one
time to any other Trustee or Trustees, provided that in no case shall less than
two Trustees personally exercise the other powers hereunder except as herein
otherwise expressly provided or unless there is only one or two Trustees.

  Section 3.5  Number of Trustees.  The number of Trustees shall be one, or such
               ------------------                                               
other number as shall be fixed from time to time by the Trustees.

Instrument.

  Section 3.7  Ownership of Assets of the Trust.  Legal title in and beneficial
               --------------------------------                                
ownership of all of the assets of the Trust shall at all times be considered as
vested in the Trust, except that the Trustees may cause legal title in and
beneficial ownership of any Trust Property to be held by, or in the name of one
or more of the Trustees acting for and on behalf of the Trust, or in the name of
any person as nominee acting for and on behalf of the Trust.  No Shareholder
shall be deemed to have a severable ownership interest in any individual asset
of the Trust or of any Series or Class, or any right of partition or possession
thereof, but each Shareholder shall have, except as otherwise provided for
herein, a proportionate undivided beneficial interest in each Series or Class
the Shares of which are owned by such Shareholders.  The Shares shall be
personal property giving only the rights specifically set forth in this Trust
Instrument.  The Trust, or at the determination of the Trustees, one or more of
the Trustees or a nominee acting for and on behalf of the Trust, shall be deemed
to hold legal title and beneficial ownership of any income earned on securities
of the Trust issued by any business entities formed, organized, or existing
under the laws of any jurisdiction, including the laws of any foreign country.

more Series or Classes, the Trustees establishing such Series or Class may
appoint, to the extent permitted by the 1940 Act, separate Trustees with respect
to such Series or Classes (the "Series Trustees").  Series Trustees may, but are
not required to, serve as Trustees of the Trust of any other Series or Class of
the Trust.  To the extent provided by the Trustees in the appointment of Series
Trustees, the Series Trustees may have, to the exclusion of any other Trustee of
the Trust, all the powers and authorities of Trustees hereunder with respect to
such Series or Class, but may have no power or authority with respect to any
other Series or Class.  Any provision of this Trust Instrument relating to
election of Trustees by Shareholders only shall entitle the Shareholders of a
Series or Class for which Series Trustees have been appointed to vote with
respect to the election of such Series Trustees and the Shareholders of any
other Series or Class shall not be entitled to participate in such vote.  In the
event that Series Trustees are appointed, the Trustees initially appointing such
Series Trustees shall, without the approval of any Outstanding Shares, amend
either this Trust Instrument or the By-laws to provide for the respective
responsibilities of the Trustees and the Series Trustees in circumstances where
an action of the Trustees or Series Trustees affects all Series of the Trust or
two or more Series represented by different Trustees.

  Section 3.9  No Accounting.  Except to the extent required by the 1940 Act or,
               -------------                                                    
if determined to be necessary or appropriate by the other Trustees under
circumstances which would justify his or her removal for cause, no person
ceasing to be a Trustee for reasons including, but not limited to, death,
resignation, retirement, removal or incapacity (nor the estate of any such
person) shall be required to make an accounting to the Shareholders or remaining
Trustees upon such cessation.

                                  ----------

                    SHAREHOLDER VOTING POWERS AND MEETINGS
                    --------------------------------------

     Section 6.1  Voting.  The Shareholders shall have power to vote only: (a)
                  ------
for the election of one or more Trustees in order to comply with the provisions
of the 1940 Act (including Section 16(a) thereof); (b) with respect to any
contract entered into pursuant to Article V to the extent required by the 1940
Act; (c) with respect to termination of the Trust or a Series or Class thereof
to the extent required by applicable law; (d) with respect to any plan adopted
pursuant to Rule 12b-1 (or any successor rule) under the 1940 Act, and related

                                      -17-
<PAGE>
 
matters, to the extent required under the 1940 Act; and (e) with respect to such
additional matters relating to the Trust as may be required by this Trust
Instrument, the By-laws or any registration of the Trust or Series as an
investment company under the 1940 Act with the Commission (or any successor
agency) or as the Trustees may consider necessary or desirable.

     On each matter submitted to a vote of Shareholders, unless the Trustees
determine otherwise, all Shares of all Series and Classes shall vote as a single
class; provided, however, that: (a) as to any matter with respect to which a
separate vote of any Series or Class is required by the 1940 Act or other
applicable law or is required by attributes applicable to any Series or Class,
such requirements as to a separate vote by that Series or Class shall apply; (b)
unless the Trustees determine that this clause (b) shall not apply in a
particular case, to the extent that a matter referred to in clause (a) above
affects more than one Series or Class and the interests of each such Series or
Class in the matter are identical, then the Shares of all such affected Series
or Classes shall vote as a single class; and (c) as to any matter which does not
affect the interests of a particular Series or Class, only the holders of Shares
of the one or more affected Series or Classes shall be entitled to vote.  Each
whole Share shall be entitled to one vote as to any matter on which it is
entitled to vote, and each fractional Share shall be entitled to a proportionate
fractional vote.  There shall be no cumulative voting in the election of
Trustees.  Shares may be voted in person or by proxy or in any manner provided
for in the By-laws.  A proxy may be given in writing, by telefax, or in any
other manner provided for in the By-laws.  Anything in this Trust Instrument to
the contrary notwithstanding, in the event a proposal by anyone other than the
officers or Trustees of the Trust is submitted to a vote of the Shareholders of
the Trust or one or more Series or Classes thereof, or in the event of any proxy
contest or proxy solicitation or proposal in opposition to any proposal by the
officers or Trustees of the Trust, Shares may be voted only in person or by
written proxy.  Until Shares are issued, the Trustees may exercise all rights of
Shareholders and may take any action required or permitted by law, this Trust
Instrument or any of the By-laws of the Trust to be taken by Shareholders.

     Section 6.2  Meetings.  Meetings of Shareholders (including meetings
                  --------
involving only the holders of Shares of one or more but less than all Series or
Classes) may be called by the Trustees from time to time to be held at such
place within or without the State of Delaware, and on such date as may be
designated in the call thereof for the purpose of taking action upon any matter
as to which the vote or authority of the Shareholders is required or permitted
as provided in Section 6.1. Special meetings of the Shareholders of any Series
may be called by the Trustees and shall be called by the Trustees upon the
written request of Shareholders owning at least twenty-five percent (25%) of the
Outstanding Shares entitled to vote, except to the extent that a lesser
percentage is prescribed by the 1940 Act. Notice shall be sent, postage prepaid,
by mail or such other means determined by the Trustees, at least 7 days prior to
any such meeting.

     Section 6.3  Quorum and Required Vote.  Unless a larger percentage is
                  ------------------------
required by law, by any provision of this Trust Instrument or by the Trustees,
one-third of the Shares entitled to vote in person or by proxy on a particular
matter shall be a quorum for the transaction of business at a Shareholders'
meeting with respect to that matter. Any lesser 

                                      -18-
<PAGE>
 
number shall be sufficient for adjournments. Any adjourned session or sessions
may be held without the necessity of further notice. Except when a larger vote
is required by law, by any provision of this Trust Instrument or by the
Trustees, a majority of the Shares voted in person or by proxy on a particular
matter at a meeting at which a quorum is present shall decide any questions with
respect to that matter and a plurality shall elect a Trustee.

     Section 6.4  Action by Written Consent.  Subject to the provisions of the
                  -------------------------
1940 Act and other applicable law, any action taken by Shareholders may be taken
without a meeting if a majority of the Shares entitled to vote on the matter (or
such larger proportion thereof as shall be required by law, by any provision of
this Trust Instrument or by the Trustees) consent to the action in writing. Such
consent shall be treated for all purposes as a vote taken at a meeting of
Shareholders. The Trustees may adopt additional rules and procedures regarding
the taking of Shareholder action by written consents.


                                  ARTICLE VII
                                  -----------

                         DISTRIBUTIONS AND REDEMPTIONS
                         -----------------------------

     Section 7.1  Distributions.
                  ------------- 

          (a)  The Trustees may from time to time declare and pay dividends or
other distributions with respect to any Series or Class. The amount of such
dividends or distributions and the payment of them and whether they are in cash
or any other Trust Property shall be wholly in the discretion of the Trustees.

          (b)  Dividends and other distributions may be paid or made to the
Shareholders of record at the time of declaring a dividend or other distribution
or among the Shareholders of record at such other date or time or dates or times
as the Trustees shall determine, which dividends or distributions, at the
election of the Trustees, may be paid pursuant to a standing resolution or
resolutions adopted only once or with such frequency as the Trustees may
determine.  All dividends and other distributions on Shares of a particular
Class shall be distributed pro rata to the Shareholders of that Series or Class
in proportion to the number of Shares of that Series or Class they held on the
record date established for such payment, except that in connection with any
dividend or distribution program or procedure the Trustees may determine that no
dividend or distribution shall be payable on Shares as to which the
Shareholder's purchase order and/or payment in the prescribed form has not been
received by the time or times established by the Trustees under such program or
procedure.  The Trustees may adopt and offer to Shareholders such dividend
reinvestment plans, cash dividend payout plans or related plans as the Trustees
shall deem appropriate.

          (c)  Anything in this Trust Instrument to the contrary
notwithstanding, the Trustees may at any time declare and distribute a stock
dividend pro rata among the Shareholders of a particular Series, or Class
thereof, as of the record date of that Series or Class fixed as provided in
Section (b) hereof. The Trustees shall have full discretion, to the extent not
inconsistent with the 1940 Act, to determine which items shall be treated as
income

                                      -19-
<PAGE>
 
and which items as capital; and each such determination and allocation shall be
conclusive and binding upon the Shareholders.

     Section 7.2  Redemption by Shareholder.
                  ------------------------- 

          (a)  Unless the Trustees otherwise determine with respect to a
particular Series or Class at the time of establishing and designating the same,
each holder of Shares of a particular Series or Class thereof shall have the
right at such times as may be permitted by the Trust, but no less frequently
than once each week, to require the Trust to redeem (out of the assets belonging
to the applicable Series or Class) all or any part of his Shares at a redemption
price equal to the Net Asset Value per Share of that Series or Class next
determined in accordance with Section 7.4 after the Shares are properly tendered
for redemption, less such redemption fee or other charge, if any, as may be
fixed by the Trustees.  Except as otherwise provided in this Trust Instrument,
payment of the redemption price shall be in cash; provided, however, that to the
extent permitted by applicable law, the Trustees may authorize the Trust to make
payment wholly or partly in securities or other assets belonging to the
applicable Series at the value of such securities or assets used in such
determination of Net Asset Value.

          (b)  Notwithstanding the foregoing, the Trust may postpone payment of
the redemption price and may suspend the right of the holders of Shares of any
Series or Class to require the Trust to redeem Shares of that Series or Class
during any period or at any time when and to the extent permissible under the
1940 Act.

          (c)  In the event that a Shareholder shall submit a request for the
redemption of a greater number of Shares than are then allocated to such
Shareholder, such request shall not be honored.

     Section 7.3  Redemption by Trust.  Unless the Trustees otherwise determine
                  -------------------                                          
with respect to a particular Series or Class at the time of establishing and
designating the same, each Share of each Series or Class thereof that has been
established and designated is subject to redemption (out of the assets belonging
to the applicable Series or Class) by the Trust at the redemption price which
would be applicable if such Share was then being redeemed by the Shareholder
pursuant to Section 7.2 at any time if the Trustees determine in their sole
discretion that failure to so redeem may have materially adverse consequences to
the holders of the Shares, or any Series or Class of the Trust, and upon such
redemption the holders of the Shares so redeemed shall have no further right
with respect thereto other than to receive payment of such redemption price.  In
addition, the Trustees, in their sole discretion, may cause the Trust to redeem
(out of the assets belonging to the applicable Series or Class) all of the
Shares of one or more Series or Classes held by (a) any Shareholder if the value
of such Shares held by such Shareholder is less than the minimum amount
established from time to time by the Trustees, (b) all Shareholders of one or
more Series or Classes if the value of such Shares held by all Shareholders is
less than the minimum amount established from time to time by the Trustees or
(c) any Shareholder to reimburse the Trust for any loss or expense it has
sustained or incurred by reason of the failure of such Shareholder to make full
payment for Shares purchased by such Shareholder, or by reason of any defective
redemption request, or by reason of indebtedness incurred because of such
Shareholder as described in Section 9.11 or to 

                                      -20-
<PAGE>
 
collect any charge relating to a transaction effected for the benefit of such
Shareholder or as provided in the prospectus relating to such Shares.

     Section 7.4  Net Asset Value. The Net Asset Value per Share of any Series
                  ---------------  
or Class thereof shall be the quotient obtained by dividing the value of the net
assets of that Series or Class (being the value of the assets belonging to that
Series or Class less the liabilities belonging to that Series or Class) by the
total number of Shares of that Series or Class outstanding, all determined in
accordance with the methods and procedures, including without limitation those
with respect to rounding, established by the Trustees from time to time.

          The Trustees may determine to maintain the Net Asset Value per Share
of any Series at a designated constant dollar amount and in connection therewith
may adopt procedures not inconsistent with the 1940 Act for the continuing
declarations of income attributable to that Series or Class thereof as dividends
payable in additional Shares of that Series or Class thereof at the designated
constant dollar amount and for the handling of any losses attributable to that
Series or Class thereof.  Such procedures may, among other things, provide that
in the event of any loss each Shareholder of a Series or Class thereof shall be
deemed to have contributed to the capital of the Trust attributable to that
Series or Class thereof his pro rata portion of the total number of Shares
required to be cancelled in order to permit the Net Asset Value per Share of
that Series or Class thereof to be maintained, after reflecting such loss, at
the designated constant dollar amount.  Each Shareholder of the Trust shall be
deemed to have agreed, by his investment in the Trust, to make the contribution
referred to in the preceding sentence in the event of any such loss.


                                 ARTICLE VIII
                                 ------------

                  LIMITATION OF LIABILITY AND INDEMNIFICATION
                  -------------------------------------------

     Section 8.1  Limitation of Liability. Neither a Trustee nor an officer of
                  -----------------------    
the Trust, when acting in such capacity, shall be personally liable to any
person other than the Trust or a beneficial owner for any act, omission or
obligation of the Trust, any Trustee or any officer of the Trust. Neither a
Trustee nor an officer of the Trust shall be liable for any act or omission in
his capacity as Trustee or as an officer of the Trust, or for any act or
omission of any other officer or any employee of the Trust or of any other
person or party, provided that nothing contained herein or in the Act shall
protect any Trustee or officer against any liability to the Trust or to
Shareholders to which he would otherwise be subject by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of the office of Trustee or the duties of such officer
hereunder.

     Section 8.2  Indemnification. The Trust shall indemnify each of its
                  ---------------  
Trustees and officers and persons who serve at the Trust's request as directors,
officers or trustees of another organization in which the Trust has any interest
as a shareholder, creditor, or otherwise, and may indemnify any trustee,
director or officer of a predecessor organization (each a "Covered Person"),
against all liabilities and expenses (including amounts paid in satisfaction of
judgments, in compromise, as fines and penalties, and expenses including

                                      -21-
<PAGE>
 
reasonable accountants' and counsel fees) reasonably incurred in connection with
the defense or disposition of any action, suit or other proceeding, whether
civil or criminal, before any court or administrative or legislative body, in
which he may be involved or with which he may be threatened, while as a Covered
Person or thereafter, by reason of being or having been such a Covered Person,
except that no Covered Person shall be indemnified against any liability to the
Trust or its Shareholders to which such Covered Person would otherwise be
subject by reason of bad faith, willful misfeasance, gross negligence or
reckless disregard of his duties involved in the conduct of such Covered
Person's office (such willful misfeasance, bad faith, gross negligence or
reckless disregard being referred to herein as "Disabling Conduct"). Expenses,
including accountants' and counsel fees so incurred by any such Covered Person
(but excluding amounts paid in satisfaction of judgments, in compromise or as
fines or penalties), may be paid from time to time by the Trust in advance of
the final disposition of any such action, suit or proceeding upon receipt of (a)
an undertaking by or on behalf of such Covered Person to repay amounts so paid
to the Trust if it is ultimately determined that indemnification of such
expenses is not authorized under this Article VIII and either (b) such Covered
Person provides security for such undertaking, (c) the Trust is insured against
losses arising by reason of such payment, or (d) a majority of a quorum of
disinterested, non-party Trustees, or independent legal counsel in a written
opinion, determines, based on a review of readily available facts, that there is
reason to believe that such Covered Person ultimately will be found entitled to
indemnification.

     Section 8.3  Indemnification Determinations.  Indemnification of a Covered
                  ------------------------------                               
Person pursuant to Section 8.2 shall be made if (a) the court or body before
whom the proceeding is brought determines, in a final decision on the merits,
that such Covered Person was not liable by reason of Disabling Conduct or (b) in
the absence of such a determination, a majority of a quorum of disinterested,
non-party Trustees or independent legal counsel in a written opinion make a
reasonable determination, based upon a review of the facts, that such Covered
Person was not liable by reason of Disabling Conduct.

     Section 8.4  Indemnification Not Exclusive.  The right of indemnification
                  -----------------------------                               
provided by this Article VIII shall not be exclusive of or affect any other
rights to which any such Covered Person may be entitled.  As used in this
Article VIII, "Covered Person" shall include such person's heirs, executors and
administrators, and a "disinterested, non-party Trustee" is a Trustee who is
neither an Interested Person of the Trust nor a party to the proceeding in
question.

     Section 8.5  Shareholders. Each Shareholder of the Trust and of each Series
                  ------------ 
or Class shall not be personally liable for the debts, liabilities, obligations
and expenses incurred by, contracted for, or otherwise existing with respect to,
the Trust or by or on behalf of any Series or Class.  The Trustees shall have no
power to bind any Shareholder personally or to call upon any Shareholder for the
payment of any sum of money or assessment whatsoever other than such as the
Shareholder may  at any time personally agree to pay pursuant to terms hereof or
by way of subscription for any Shares or otherwise.

     In case any Shareholder or former Shareholder of any Series or Class shall
be held to be personally liable solely by reason of his being or having been a
Shareholder of such Series 

                                      -22-
<PAGE>
 
or Class and not because of his acts or omissions or for some other reason, the
Shareholder or former Shareholder (or his heirs, executors, administrators or
other legal representatives, or, in the case of a corporation or other entity,
its corporate or other general successor) shall be entitled out of the assets
belonging to the applicable Series or Class to be held harmless from and
indemnified against all loss and expense arising from such liability. The Trust,
on behalf of the affected Series, shall, upon request by the Shareholder, assume
the defense of any claim made against the Shareholder for any act or obligation
of the Series or Class and satisfy any judgment thereon from the assets of the
Series or Class. The indemnification and reimbursement required by the preceding
sentence shall be made only out of assets of the one or more Series or Classes
whose Shares were held by said Shareholder at the time the act or event occurred
which gave rise to the claim against or liability of said Shareholder. The
rights accruing to a Shareholder under this Section shall not impair any other
right to which such Shareholder may be lawfully entitled, nor shall anything
herein contained restrict the right of the Trust or any Series or Class thereof
to indemnify or reimburse a Shareholder in any appropriate situation even though
not specifically provided herein.


                                  ARTICLE IX
                                  ----------

                                 MISCELLANEOUS
                                 -------------

     Section 9.1  Trust Not a Partnership. It is hereby expressly declared that
                  -----------------------    
a trust and not a partnership is created hereby. All persons extending credit
to, contracting with or having any claim against any Series of the Trust or any
Class within any Series shall look only to the assets of such Series or Class
for payment under such credit, contract or claim; and neither the Shareholders
nor the Trustees, nor any of the Trust's officers, employees or agents, whether
past, present or future, shall be personally liable therefor. Every note, bond,
contract or other undertaking issued by or on behalf of the Trust or the
Trustees relating to the Trust or to a Series or Class shall include a
recitation limiting the obligations represented thereby to the Trust or to one
or more Series or Classes and its or their assets (but the omission of such a
recitation shall not operate to bind any Shareholder, Trustee, officer, employee
or agent of the Trust).


     Section 9.2  Trustees' Good Faith Action, Expert Advice, No Bond or Surety.
                  ------------------------------------------------------------- 
The exercise by the Trustees of their powers and discretions hereunder shall be
binding upon everyone interested.  Subject to the provisions of Article VIII:
(i) the Trustees shall not be responsible or liable in any event for any neglect
or wrongdoing of any officer, agent, employee, consultant, adviser,
administrator, distributor or principal underwriter, custodian or transfer,
dividend disbursing, Shareholder servicing or accounting agent of the Trust, nor
shall any Trustee be responsible for the act or omission of any other Trustee;
(ii) the Trustees may take advice of counsel or other experts with respect to
the meaning and operation of this Trust Instrument and their duties as Trustees,
and shall be under no liability for any act or omission in accordance with such
advice or for failing to follow such advice; and (iii) in discharging 

                                      -23-
<PAGE>
 
their duties, the Trustees, when acting in good faith, shall be entitled to rely
upon the books of account of the Trust and upon written reports made to the
Trustees by any officer appointed by them, any independent public accountant,
and (with respect to the subject matter of the contract involved) any officer,
partner or responsible employee of a contracting party appointed by the
Trustees. The Trustees as such shall not be required to give any bond or surety
or any other security for the performance of their duties.

     Section 9.3  Establishment of Record Dates. The Trustees may close the
                  -----------------------------   
Share transfer books of the Trust for a period not exceeding one hundred twenty
(120) days preceding the date of any meeting of Shareholders, or the date for
the payment of any dividends or other distributions, or the date for the
allotment of rights, or the date when any change or conversion or exchange of
Shares shall go into effect; or in lieu of closing the stock transfer books as
aforesaid, the Trustees may fix in advance a date, not exceeding one hundred
twenty (120) days preceding the date of any meeting of Shareholders, or the date
for payment of any dividend or other distribution, or the date for the allotment
of rights, or the date when any change or conversion or exchange of Shares shall
go into effect, as a record date for the determination of the Shareholders
entitled to notice of, and to vote at, any such meeting, or entitled to receive
payment of any such dividend or other distribution, or to any such allotment of
rights, or to exercise the rights in respect of any such change, conversion or
exchange of Shares, and in such case such Shareholders and only such
Shareholders as shall be Shareholders of record on the date so fixed shall be
entitled to such notice of, and to vote at, such meeting, or to receive payment
of such dividend or other distribution, or to receive such allotment or rights,
or to exercise such rights, as the case may be, notwithstanding any transfer of
any Shares on the books of the Trust after any such record date fixed as
aforesaid.

     Section 9.4  Dissolution and Termination of Trust or Series.
                  ---------------------------------------------- 

          (a)  This Trust shall continue without limitation of time but subject
to the provisions of sub-sections (b) and (c) of this Section 9.4.

          (b)  Notwithstanding anything in Section 9.5 to the contrary, the
Trustees may without Shareholder approval (unless such approval is required by
the 1940 Act) in dissolution of the Trust or an applicable Series or Class,

               (i)     sell and convey all or substantially all of the assets of
                       the Trust or any Series or Class to another trust,
                       partnership, limited liability company, association or
                       corporation, or to a separate Series or Class of shares
                       thereof, organized under the laws of any state or
                       jurisdiction, for adequate consideration which may
                       include the assumption of all outstanding obligations,
                       taxes and other liabilities, accrued or contingent, of
                       the Trust or any Series or Class, and which may include
                       shares of beneficial interest, stock or other ownership
                       interests of such trust, partnership, limited liability
                       company, association or corporation or of a series
                       thereof; or

                                      -24-
<PAGE>
 
               (ii)    at any time sell and convert into money all of the assets
                       of the Trust or any Series or Class.

     Following a sale or conversion in accordance with the foregoing sub-section
9.4(b)(i) or (ii), and upon making reasonable provision, in the determination of
the Trustees, for the payment of all liabilities of the Trust or the affected
Series or Class as required by applicable law, by such assumption or otherwise,
the Shareholders of each Class of a Series involved in such sale or conversion
shall be entitled to receive, as a Class, when and as declared by the Trustees,
the excess of the assets belonging to that Series that are allocated to such
Class over the liabilities belonging to that Series that are allocated to such
Class.  The assets so distributable to the Shareholders of any particular Class
of a Series shall be distributed among such Shareholders in proportion to the
number of Shares of that Class held by them and recorded on the books of the
Trust.  In the event a Series is not divided into Classes, the foregoing
provisions shall be applied on a Series by Series basis.

          (c)  Upon completion of the distribution of the remaining proceeds or
the remaining assets as provided in sub-section (b), the Trust (in the case of a
sale or conversion with respect to the Trust as a whole or the last remaining
Series) or any affected Series or Class shall terminate and the Trustees and the
Trust or any affected Series or Class shall be discharged of any and all further
liabilities and duties hereunder and the right, title and interest of all
parties with respect to the Trust or such affected Series or Class shall be
cancelled and discharged.

     Upon termination of the Trust, following completion of winding up of its
business, the Trustees shall cause a certificate of cancellation of the Trust's
certificate of trust to be filed in accordance with the Act, which certificate
of cancellation may be signed by any one Trustee.

     Section 9.5  Merger, Consolidation, Incorporation.  Anything in this Trust
                  ------------------------------------                         
Instrument to the contrary notwithstanding, the Trustees, in order to change the
form of organization and/or domicile of the Trust, may, without prior
Shareholder approval, (i) cause the Trust to merge or consolidate with or into
one or more trusts, partnerships, limited liability companies, associations or
corporations which is or are formed, organized or existing under the laws of a
state, commonwealth possession or colony of the United States, or (ii) cause the
Trust to incorporate under the laws of Delaware.  Any agreement of merger or
consolidation or certificate of merger may be signed by a majority of the
Trustees.  Pursuant to and in accordance with the provisions of Section 3815(f)
of the Act, and notwithstanding anything to the contrary contained in this Trust
Instrument, an agreement of any merger or consolidation approved in accordance
with this Section 9.5 may effect any amendment to the Trust Instrument or effect
the adoption of a new trust instrument of the Trust if it is the surviving or
resulting trust in the merger or consolidation.  Any merger or consolidation of
the Trust other than as described in the foregoing provisions of this Section

                  --------------------------------------   
of this Trust Instrument and of each amendment hereof or Trust Instrument
supplemental hereto shall be kept at the office of the Trust where it may be
inspected by any Shareholder.  Anyone dealing with the Trust may rely on a
certificate by an officer or Trustee of the Trust as to whether or not any such
amendments or supplements have been made and as to any matters in connection
with the Trust hereunder, and with the same effect as if it were the original,
may rely on a copy certified by an officer or Trustee of the Trust to be a copy
of this Trust Instrument or of any such amendment or supplemental Trust
Instrument.  In this Trust Instrument or in any such amendment or supplemental
Trust Instrument, references to this Trust Instrument, and all expressions like
"herein," "hereof" and "hereunder," shall be deemed to refer to this Trust
Instrument as amended or affected by any such supplemental Trust Instrument.
All expressions like "his", "he" and "him", shall be deemed to include the
feminine and neuter, as well as masculine, genders.  Headings are placed herein
for convenience of reference only and in case of any conflict, the text of this
Trust Instrument rather than the headings, shall control.  This Trust Instrument
may be executed in any number of counterparts each of which shall be deemed an
original.

     Section 9.7  Applicable Law. The trust set forth in this instrument is made
                  --------------    
in the State of Delaware, and the Trust and this Trust Instrument, and the
rights and obligations of the Trustees and Shareholders hereunder, are to be
governed by and construed and administered according to the Act and the laws of
said State; provided, however, that there shall not be applicable to the Trust,
the Trustees or this Trust Instrument (a) the provisions of Section 3540 of
Title 12 of the Delaware Code or (b) any provisions of the laws (statutory or
common) of the State of Delaware (other than the Act) pertaining to trusts which
relate to or regulate: (i) the filing with any court or governmental body or
agency of trustee accounts or schedules of trustee fees and charges, (ii)
affirmative requirements to post bonds for trustees, officers, agents or
employees of a trust, (iii) the necessity for obtaining court or other
governmental approval concerning the acquisition, holding or disposition of real
or personal property, (iv) fees or other sums payable to trustees, officers,
agents or employees of a trust, (v) the allocation of receipts and expenditures
to income or principal, (vi) restrictions or limitations on the permissible
nature, amount or concentration of trust investments or requirements relating to
the titling, storage or other manner of holding of trust assets, or (vii) the
establishment of fiduciary or other standards or responsibilities or limitations
on the acts or powers of trustees, which are inconsistent with the limitations
or liabilities or authorities and powers of the Trustees set forth or referenced
in this Trust Instrument.  The Trust shall be of the type commonly called a
"business trust", and without limiting the provisions hereof, the Trust may
exercise all powers which are ordinarily exercised by such a trust under
Delaware law.  The Trust specifically reserves the right to exercise any of the
powers or privileges afforded to trusts or actions that may be engaged in by
trusts under the Act, and the absence of a specific reference herein to any such
power, privilege or action shall not imply that the Trust may not exercise such
power or privilege or take such actions.

     Section 9.8  Amendments. Except as specifically provided herein, the
                  ----------     
Trustees may, without Shareholder vote, amend or otherwise supplement this Trust
Instrument by making an amendment, a Trust Instrument supplemental hereto or an
amended and restated trust

instrument. Shareholders shall have the right to vote: (i) on any amendment
which would affect their right to vote granted in Section 6.1, (ii) on any
amendment to this Section 9.8, (iii) on any amendment for which such vote is
required by law and (iv) on any amendment submitted to them by the Trustees. Any
amendment required or permitted to be submitted to Shareholders which, as the
Trustees determine, shall affect the Shareholders of one or more Series or
Classes shall be authorized by vote of the Shareholders of each Series or Class
affected and no vote of shareholders of a Series or Class not affected shall be
required. Anything in this Trust Instrument to the contrary notwithstanding, any
amendment to Article VIII hereof shall not limit the rights to indemnification
or insurance provided therein with respect to action or omission of any persons
protected thereby prior to such amendment.

     Section 9.9   Fiscal Year.  The fiscal year of the Trust shall end on a
                   -----------                                              
specified date as determined from time to time by the Trustees.

     Section 9.10  Provisions in Conflict with Law. The provisions of this Trust
                   -------------------------------      
Instrument are severable, and if the Trustees shall determine, with the advice
of counsel, that any of such provisions is in conflict with the 1940 Act, the
regulated investment company provisions of the Internal Revenue Code or with
other applicable laws and regulations, the conflicting provision shall be deemed
never to have constituted a part of this Trust Instrument; provided, however,
that such determination shall not affect any of the remaining provisions of this
Trust Instrument or render invalid or improper any action taken or omitted prior
to such determination.  If any provision of this Trust Instrument shall be held
invalid or unenforceable in any jurisdiction, such invalidity or
unenforceability shall attach only to such provision in such jurisdiction and
shall not in any manner affect such provisions in any other jurisdiction or any
other provision of this Trust Instrument in any jurisdiction.

     Section 9.11  Allocation of Certain Expenses. Each Shareholder will, at the
                   ------------------------------   
discretion of the Trustees, indemnify the Trust against all expenses and losses
resulting from indebtedness incurred in connection with facilitating (i)
requests pending receipt of the collected funds from investments sold on the
date of such Shareholder's redemption request; (ii) redemption requests from
such Shareholder who has also notified the Trust of its intention to deposit
funds in its accounts on the date of said redemption request; or (iii) the
purchase of investments pending receipt of collected funds from such Shareholder
who has notified the Trust of its intention to deposit funds in its accounts on
the date of the purchase of the investments.

     IN WITNESS WHEREOF, the undersigned, being the Trustee of the Trust, has
executed this Declaration of Trust as of the 21st day of October, 1998.

notification of such meeting at least seven days before the meeting, to such
address as may be registered with the Trust by the Shareholder.  Notice of any
Shareholder meeting need not be given to any Shareholder if a written waiver of
notice, executed before or after such meeting, is filed with the record of such
meeting, or to any Shareholder who shall attend such meeting in person or by
proxy.  Notice of adjournment of a Shareholders' meeting to another time or

Shareholder in writing and dated not more than eleven months before the meeting,
unless the instrument specifically provides for a longer period or (ii) the
Trustees adopt by resolution an electronic, telephonic, computerized or other
alternative to execution of a written instrument authorizing the proxy to act,
which authorization is received not more than eleven months before the meeting.
Proxies shall be delivered to the Secretary of the Trust or other person
responsible for recording the proceedings before being voted. A proxy with
respect to Shares held in the name of two or more persons shall be valid if
executed by one of them unless at or prior to exercise of such proxy the Trust

herein or in the Trust Instrument, all matters relating to the giving, voting or

and shall be signed by the President or a Vice President and by the Treasurer,
Assistant Treasurer, Secretary or Assistant Secretary. Such signatures may be

shall not affect the ownership of Shares in the Trust.

          The Trustees shall from time to time determine whether and to what
extent, and at what times and places, and under what conditions and regulations

the Investment Adviser believes to be capable of assisting in the performance of
its obligations under this Agreement (each a "Sub-Adviser") and to terminate the
services of any such person; provided, however, that the compensation of such
person or persons shall be paid by the Investment Adviser and that the
Investment Adviser shall be as fully responsible to the Trust for the acts and
omissions of any 

                                      -2-

public, the Investment Adviser shall reimburse such Portfolio for one-half of
any excess up to the amount of the fees payable by the particular Portfolio to
it during such fiscal year pursuant to Paragraph 7 hereof; provided, however,

                            DISTRIBUTION AGREEMENT
                            ----------------------

          Agreement dated February __, 1999 between PROVIDENT INSTITUTIONAL
FUNDS, a Delaware business trust, (the "Company"), and PROVIDENT DISTRIBUTORS,
INC., a Delaware corporation (the "Distributor").

          WHEREAS, the Company is an open-end, diversified management investment
company and is so registered under the Investment Company Act of 1940, as
amended (the "1940 Act"); and

          WHEREAS, the Company desires to retain the Distributor as its
distributor to provide for the sale and distribution of each class and series of
shares ("shares") in each of the Company's investment portfolios (individually,
a "Fund," collectively, the "Funds") as listed on Appendix A (as such Appendix
may, from time to time, be supplemented (or amended)), and the Distributor is
willing to render such services;

          NOW, THEREFORE, in consideration of the premises and mutual covenants
set forth and intending to be legally bound, the parties hereto agree as
follows:

          1.   APPOINTMENT OF DISTRIBUTOR.  The Company hereby appoints the
               --------------------------                                  
Distributor as distributor of each class and series of shares in each of the
Company's Funds on the terms and for the period set forth in this Agreement.
The Distributor hereby accepts such appointment and agrees to render the
services and duties set forth in Section 2 below.  In the event that the Company
establishes additional classes or investment portfolios other than the Funds
listed on Appendix A with respect to which it desires to retain the Distributor
to act as distributor hereunder, the Company shall notify the Distributor,
whereupon such Appendix A shall be supplemented (or amended) and such portfolio
shall become a Fund hereunder and shall be subject to the provisions of this
Agreement to the same extent as the Funds (except to the extent that said
provisions may be modified in writing by the Company and Distributor at the
time).

          2.   SERVICES AND DUTIES.  The Distributor enters into the following
               -------------------                                            
covenants with respect to its services and duties:

               a.   The Distributor agrees to sell, as agent, from time to time
during the term of this Agreement, shares upon the terms and at the current
offering price as described in the Prospectuses. The Distributor will act only
in its own behalf as principal in making agreements with selected dealers. No
brokerdealer or other person which enters into a selling or servicing agreement
with the Distributor shall be authorized to act as agent for the Company or its
Funds in connection with the offering or sale of shares to the public or
otherwise. The Distributor shall use its best efforts to sell shares of each
<PAGE>
 
class or series of each of the Funds but shall not be obligated to sell any
certain number of shares.

               b.   The Distributor shall prepare or review, provide advice with
respect to, and file with the federal and state agencies or other organization
as required by federal, state, or other applicable laws and regulations, all
sales literature (advertisements, brochures and shareholder communications) for
each of the Funds and any class or series thereof.

               c.   In performing all of its services and duties as Distributor,
the Distributor will act in conformity with the Declaration of Trust, By-Laws,
Prospectuses and resolutions and other instructions of the Company's Board of
Trustees and will comply with the requirements of the Securities Act of 1933, as
amended (the "1933 Act"), the Securities Exchange Act of 1934, the 1940 Act and
all other applicable federal or state law.

               d.   The Distributor will bear the cost of (i) printing and
distributing any Prospectus (including any supplement thereto) to persons who
are not shareholders, and (ii) preparing, printing and distributing any
literature, advertisement or material which is primarily intended to result in
the sale of shares; provided, however, that the Distributor shall not be
                    --------  -------                                   
obligated to bear the expenses incurred by the Company in connection with the
preparation and printing of any amendment to any Registration Statement or
Prospectus necessary for the continued effective registration of the shares
under the 1933 Act and state securities laws and the distribution of any such
document to existing shareholders of the Company's Funds.

               e.   The Company shall have the right to suspend the sale of
shares at any time in response to conditions in the securities markets or
otherwise, and to suspend the redemption of shares of any Fund at any time
permitted by the 1940 Act or the rules and regulations of the Commission
("Rules").

               f.   The Company reserves the right to reject any order for
shares but will not do so arbitrarily, or without reasonable cause.

          3.   LIMITATIONS OF LIABILITY. The Distributor shall not be liable for
               ------------------------                                       
any error of judgment or mistake of law or for any loss suffered by the Company
in connection with the matters to which this Agreement relates, except a loss
resulting from willful misfeasance, bad faith or gross negligence on its part in
the performance of its duties or from reckless disregard by it of its
obligations and duties under this Agreement.

          4.   PROPRIETARY AND CONFIDENTIAL INFORMATION.  The Distributor agrees
               ----------------------------------------                         
on behalf of itself and its employees to treat confidentially and as proprietary
information of the Company all 

                                      -2-
<PAGE>
 
records and other information relative to the Company and its Funds and prior,
present or potential shareholders, and not to use such records and information
for any purpose other than performance of its responsibilities and duties
hereunder, except after prior notification to and approval in writing by the
Company, which approval shall not be unreasonably withheld and may not be
withheld where the Distributor may be exposed to civil or criminal contempt
proceedings for failure to comply, when requested to divulge such information by
duly constituted authorities, or when so requested by the Company.

          5.   INDEMNIFICATION.
               --------------- 

               a.   The Company represents and warrants to the Distributor that
the Registration Statement contains, and that the Prospectuses at all times will
contain, all statements required by the 1933 Act and the Rules of the
Commission, will in all material respects conform to the applicable requirements
of the 1933 Act and the Rules and will not include any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, except that no representation or warranty
in this Section 5 shall apply to statements or omissions made in reliance upon
and in conformity with written information furnished to the Company by or on
behalf of the Distributor or either of the Company's co-administrators expressly
for use in the Registration Statement or Prospectuses.

               b.   The Company on behalf of each Fund agrees that each Fund
will indemnify, defend and hold harmless the Distributor, its several officers,
and directors, and any person who controls the Distributor within the meaning of
Section 15 of the 1933 Act, from and against any losses, claims, damages or
liabilities, joint or several, to which the Distributor, its several officers,
and directors, and any person who controls the Distributor within the meaning of
Section 15 of the 1933 Act, may become subject under the 1933 Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement, the Prospectuses or in any application or other document
executed by or on behalf of the Company with respect to such Fund or are based
upon information furnished by or on behalf of the Company with respect to such
Fund filed in any state in order to qualify the shares under the securities or
blue sky laws thereof ("Blue Sky application") or arise out of, or are based
upon, the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and will reimburse the Distributor, its several officers, and directors, and any
person who controls the Distributor within the meaning of Section 15 of the 1933
Act, for any legal or other expenses 

                                      -3-
<PAGE>
 
reasonably incurred by the Distributor, its several officers, and directors, and
any person who controls the Distributor within the meaning of Section 15 of the
1933 Act, in investigating, defending or preparing to defend any such action,
proceeding or claim; provided, however, that the Company shall not be liable in
                     --------  ------- 
any case to the extent that such loss, claim, damage or liability arises out of,
or is based upon, any untrue statement, alleged untrue statement, or omission or
alleged omission made in the Registration Statement, the Prospectus or any Blue
Sky application with respect to such Fund in reliance upon and in conformity
with written information furnished to the Company by or on behalf of the
Distributor or either of the Company's coadministrators specifically for
inclusion therein or arising out of the failure of the Distributor to deliver a
current Prospectus.

               c.   The Company on behalf of each Fund shall not indemnify any
person pursuant to this Section 5 unless the court or other body before which
the proceeding was brought has rendered a final decision on the merits that such
person was not liable by reason of his or her willful misfeasance, bad faith or
gross negligence in the performance of his or her duties, or his or her reckless
disregard of any obligations and duties, under this Agreement ("disabling
conduct") or, in the absence of such a decision, a reasonable determination
(based upon a review of the facts) that such person was not liable by reason of
disabling conduct has been made by the vote of a majority of a quorum of the
trustees of the Company who are neither "interested parties" (as defined in the
1940 Act) nor parties to the proceeding, or by independent legal counsel in a
written opinion.

               d.   The Distributor will indemnify and hold harmless the Company
and each of its Funds and its several officers and trustees, and any person who
controls the Company within the meaning of Section 15 of the 1933 Act, from and
against any losses, claims, damages or liabilities, joint or several, to which
any of them may become subject under the 1933 Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) arise out of, or are based upon, any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement, the

              N-1A for Prudential Institutional Funds (Registration Nos. 
              ----------------------------------------------------------

              ------------------

Ladies and Gentlemen:

         We have acted as counsel to Provident Institutional Funds, a Delaware
business trust (the "Trust"), in connection with the preparation and filing with
the Securities and Exchange Commission of the Post-Effective Amendment No. 61 to
the Trust's Registration Statement on Form N-1A under the Securities Act of
1933, as amended, and the Investment Company Act of 1940, as amended.

         The Trust is authorized to issue an unlimited number of shares of
beneficial interest (the "Shares"), with no par value. The Board of Trustees of
the Trust has the power to create and establish one or more series of Shares and
one or more classes of Shares within such series and to classify or reclassify
any unissued Shares with respect to such series and classes.

         We have reviewed the Trust's Agreement and Declaration of Trust,
By-Laws, and resolutions adopted by Board of Trustees of the Trust and such
other legal and factual matters as we have deemed appropriate. We have assumed
that the Shares will be issued against payment therefor as described in the
Trust's Prospectuses.

         This opinion is based exclusively on the Delaware Business Trust Act
and the federal law of the United States of America.
<PAGE>
 
         Currently, the Trust is authorized to offer Shares of the following
series and classes within such series:


Series and Classes                       Series and Classes
- ------------------                       ------------------

Series A (TempFund)                      Series F (Treasury Trust Fund)

      Class A Fund Shares                     Class A Fund Shares
      Class B Dollar Shares                   Class B Dollar Shares

Series B (TempCash)                      Series G (MuniFund)

      Class A Fund Shares                     Class A Fund Shares
      Class B Fund Shares                     Class B Dollar Shares


Series C (FedFund)                       Series H (MuniCash)

     Class A Fund Shares                      Class A Fund Shares
     Class B Dollar Shares                    Class B Dollar Shares

Series D (T-Fund)                        Series I (California Money Fund)

     Class A Fund Shares                      Class A Fund Shares
     Class B Dollar Shares                    Class B Dollar Shares
     Class C Plus Shares                      Class C Plus Shares

Series E (Federal Trust Fund)            Series J (New York Money Fund)

     Class A Fund Shares                      Class A Fund Shares
     Class B Dollar Shares                    Class B Dollar Shares
                                              Class C Plus Shares

         Based on the foregoing, it is our opinion that the Shares of the Trust
will be validly issued, fully paid and non-assessable by the Trust, and that the
holders of the Shares of the Trust will be entitled to the same limitation of
personal liability extended to stockholders of private corporations for profit
organized under the general corporation law of the State of Delaware (except
that we express no opinion as to such holders who are also trustees of the
Trust).

         We hereby consent to the filing of this opinion as an exhibit to the
Trust's Post-Effective Amendment No. 61 to Registration Statement on Form N-1A.

<PAGE>
 
                  Section 2.   You will provide such office space and equipment,
telephone facilities and personnel (which may be any part of the space,

                  Section 3.   Neither you nor any of your officers, employees
or agents are authorized to make any representations concerning us or the Shares
except those contained in a Series's applicable prospectuses and statements of
additional information for the Shares, copies of which will be supplied by us to
you, or in such supplemental literature or advertising as may be authorized by
us in writing.

                  Section 4.   For all purposes of this Agreement you will be
deemed to be an independent contractor, and will have no authority to act as
agent for us or a Series in any matter or in any respect. By your written
acceptance of this Agreement, you agree to and do release, indemnify and hold us
harmless and a Series harmless from and against any and all direct or indirect

such portion of any fee payable to you hereunder to the extent necessary to
assure that such fee and other expenses required to be accrued hereunder on any

and the Trust, and the Trust's trustees will review, at least quarterly, a
written report of the amounts so expended and the purposes for which such
expenditures were made. In addition, you will furnish us or our designees with

represent, warrant and agree that the compensation payable to you hereunder,
together with any other compensation you receive from Customers for services
contemplated by this Agreement, will be disclosed by you to your Customers, will
be authorized by your Customers and will not be excessive or unreasonable under
the laws and instruments governing your relationships with Customers. In
addition, you understand that this Agreement has been entered into pursuant to
Rule 12b-1 under the Act, and is subject to the provisions of said Rule, as well

        Rule 18f-3, which became effective on April 3, 1995, requires an
investment company to file with the Commission a written plan specifying all of

(collectively "Plans and Related Agreements") and (ii) any other incremental
expenses identified that should be properly allocated to one class, approved by
the Board of Trustees, including a majority of the trustees who are not
interested persons of the Trust; and (b) the fact that (i) a class will vote
separately on matters which pertain to the Plans and Agreements and(ii) each
class will vote separately on any matter submitted to shareholders relating to
class expenses; (c) the designation of each class of shares of a Series; and (d)
the different shareholder services relating to a class of shares and (e) the
dividends that may be paid to the holders of shares of each class.
