RISK/RETURN SUMMARY:  INVESTMENTS AND RISKS

Investment Objective of the Portfolio

          The Portfolio's investment objective is to seek the highest total
return by investing primarily in Commercial Mortgage-Backed Securities.  The
investment objective may be changed by the Fund's Board of Trustees without
shareholder approval.

Main Investment Strategies of the Portfolio

          Mortgage-Backed Securities.  The Portfolio seeks the highest total
return by investing in a variety of debt securities whose principal and interest
payments are tied to payments on underlying mortgage loans (Mortgage-Backed
Securities).  The Portfolio will normally invest at least 65% of its total
assets in Mortgage-Backed Securities related to mortgage loans on income
producing commercial and multi-family properties (Commercial Mortgage-Backed
Securities or CMBS).

          Commercial Mortgage-Backed Securities come in different classes that
have different risks.  The Portfolio may invest in lower, or junior, classes of
CMBS which may have a rating below investment grade and therefore are riskier
investments than higher rated securities.  The Portfolio intends to invest in
CMBS issued by private issuers as well as governmental agencies.

          The Portfolio also may invest up to 5% of its total assets in
Mortgage-Backed Securities which are related to mortgage loans on residential
properties (Residential Mortgage-Backed Securities).

          Project Loans.  The Portfolio may invest up to 15% of its total assets
in project loans (Project Loans), which are fixed income securities of issuers
whose revenues are primarily derived from mortgage loans to multi-family,
nursing home and other real estate development projects.  The principal payments
on these mortgage loans will be insured by agencies and authorities of the U.S.
Government.

          U.S. Government and Money Market Securities.  In addition to investing
in Mortgage-Backed Securities issued or guaranteed by the U.S. Treasury or
agencies and authorities of the U.S. Government, the Portfolio may invest in
U.S. Treasury and agency securities that are not Mortgage-Backed Securities
(U.S. Government Securities).  The Portfolio also may invest in money market
securities during temporary defensive periods and in order to keep cash on hand
fully invested.  Except during such temporary defensive periods, the Portfolio
will invest no more than a total of 20% of its total assets in U.S. Government
Securities and money market securities.

          REITs and REOCs.  The Portfolio may invest up to 20% of its total
assets in debt securities of (i) real estate investment trusts (REITs), which
are pooled investment vehicles that invest mainly in income producing real
estate, and (ii) real estate operating companies (REOCs),

                                       2
<PAGE>

which are companies that develop and/or manage real estate in which they have an
ownership interest.  The Portfolio may only purchase REIT and REOC securities if
they are rated investment grade at the time of investment by at least two of
Duff & Phelps, Fitch, Standard & Poor's or Moody's (Rating Agencies).

                                       3
<PAGE>


          Diversification.  The Portfolio will seek to diversify its holdings of
CMBS among different types of industries, properties and geographic regions in
order to seek to reduce risk.

          Ratings of Portfolio Securities.  The weighted average credit quality
of the Portfolio will not be less than BBB+.  The Portfolio generally will
invest in securities that are rated BBB (or Baa) or higher at the time of
investment by at least two Rating Agencies.  Securities rated BBB (or Baa) are
generally considered investment grade, but they also are considered speculative
and do carry some risks.  The Portfolio may invest up to 10% of its total assets
in split rated securities.  The Portfolio may also invest up to an aggregate of
10% of its total assets in (i) securities (other than "interest only"
securities) rated BB (or Ba) at the time of investment by at least two Rating
Agencies and (ii) "interest only" securities.

          Other Main Strategies.  The Portfolio will try to maintain a duration
for its investments of between four and eight years.  The Portfolio may invest
in futures, options and interest rate swaps, commonly known as derivatives, only
for hedging and to help maintain the interest rate risk of the Portfolio within
the target duration range.  The Portfolio may also purchase illiquid
securities.

Main Risks of Investing in the Portfolio

          As with all mutual funds, the loss of money is a risk of investing in
the Portfolio.  The following are also some of the risks of investing in the
Portfolio.

          Interest Rate Risk.  All fixed income securities are subject to the
risk that as interest rates increase, the value of the securities decrease, and
as interest rates decrease, the value of the securities increase.  Changes in
interest rates generally affect the values of securities with longer maturities
more than the values of securities with shorter maturities.  Mortgage-Backed
Securities in general, and "interest only" securities in particular, may be
particularly volatile if interest rates change.  Volatility is defined as the
characteristic of a security or a market to fluctuate significantly in price
within a short period of time.

                                       4
<PAGE>

          Commercial Mortgage-Backed Securities.    Investments in CMBS,
especially lower rated securities, involve the risks of interruptions in the
payment of interest and principal (delinquency) and the potential for loss of
principal if the property underlying the security is sold as a result of
foreclosure on the mortgage (default).  These risks include the risks associated
with direct ownership of real estate.  These risks are heightened in the case of
CMBS related to a relatively small pool of commercial mortgage loans.  In
addition, the underlying commercial properties may not be able to continue to
generate cash to meet their expenses due to a variety of economic conditions.
If the underlying borrowers cannot pay their mortgage loans, they may default
and the lenders may foreclose on the property. Finally, the ability of borrowers
to repay the commercial mortgage loans underlying CMBS will typically depend
upon the future availability of financing and the stability of real estate
values.

          For most commercial mortgage loans, the only remedy of the lender in
the event of a default is to foreclose upon the property.  If borrowers are not
able or willing to pay the principal balance on the loans, there is a good
chance that payments on the related CMBS will not be made.  Certain borrowers on
underlying mortgages may become subject to bankruptcy proceedings, in which case
the value of the related CMBS may be hurt.

          Junior classes of Mortgage-Backed Securities protect the senior class
investors against losses on the underlying mortgage loans by taking the first
loss if there are liquidations among the underlying loans.  Junior classes
generally receive principal and interest payments only after all required
payments have been made to more senior classes.  Because the Portfolio intends
to invest in junior classes of CMBS, it may not be able to recover all of its
investment in the securities it purchases.  In addition, if the underlying
mortgage portfolio has been overvalued, or if mortgage values subsequently
decline, the Portfolio may suffer significant losses.

          Investments in Mortgage-Backed Securities also carry the risk that
borrowers generally may prepay the principal on the underlying loans at any time
without penalty.  To the extent that borrowers prepay their loans, the length of
the loan will be reduced, and the Mortgage-Backed Security related to the loan
will have a lower yield.  Prepayment rates are influenced by changes in current
interest rates and a variety of economic, geographic, social and other factors.
Prepayments have increased significantly in recent years as borrowers have
refinanced higher interest rate mortgages into lower interest rate mortgages
available in the marketplace.

          Residential Mortgage-Backed Securities.  Investments in Residential
Mortgage-Backed Securities involve the same risks that affect CMBS discussed
above.  The prepayment risk may be heightened for Residential Mortgage-Backed
Securities.

          Project Loans.  The ability of issuers of Project Loans to make
interest and principal payments will be affected by events and conditions
affecting financed projects generally. These include, among other things, the
achievement and maintenance of sufficient occupancy levels and adequate rental
income, tax increases, the costs of labor, utility and other operating expenses,
the managerial ability of project managers, changes of laws and governmental
regulations and general economic conditions in the locality where the project is
being built.

                                       5

          Lower Rated Securities.  Generally, lower rated securities, which are
commonly referred to as "junk bonds," offer a higher return potential than
higher rated securities but involve greater risks. The Portfolio may invest in
securities with a BB (or Ba) rating.  Securities rated BB (or Ba) have lower
short-term prospects of default than lower rated securities, but they face major
uncertainties regarding payment of principal and interest in times of economic
difficulty and have higher prospects of default than investment grade
securities.  Lower rated securities may be less liquid than higher rated
securities and carry substantial risks with respect to their capacity to
pay interest and repay principal. An economic downturn could cause a decline in
the price of these securities because such a downturn could hurt the ability of
borrowers underlying the Mortgage-Backed Securities to make principal and
interest payments. Issuers of lower rated securities are often less financially
stable than issuers of investment grade securities. The markets for these
securities may move up and down significantly and may react strongly to
legislative and regulatory developments. The costs attributable to investing in
lower rated securities are usually higher for several reasons, such as higher
investment research costs and higher transaction costs.

          REITs and REOCs.  The value of the Portfolio's investments in REITs
will be affected by the value of the underlying properties.  The value of REIT
securities may decline when interest rates rise.  REOCs are subject to the
general risks of real estate ownership, including losses due to a downturn in
the real estate market and uninsured casualty losses.

          Illiquid Securities.    Liquidity of a security refers to the ability
to easily dispose of it and the price to be obtained, and does not necessarily
refer to the likelihood of receipt of principal or interest payments.  Illiquid
securities may be worth less than comparable, more liquid investments.  The
Portfolio intends to acquire Mortgage-Backed Securities which may be considered
illiquid because they are not registered under the federal securities laws,
contractual restrictions on transfer apply or they are part of a small issue.
The Portfolio may purchase securities offered in private placements or under
Rule 144A of the Securities Act of 1933, which may also be illiquid.  If a
security is illiquid, the Portfolio may not be able to dispose of it at the time
or price which it would like.

          Derivatives. The Portfolio's use of derivatives may reduce returns
and/or increase volatility.

          General.  An investment in the Portfolio is not a deposit of PNC Bank,
National Association or any other bank and is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other governmental agency.

          The Portfolio is a "non-diversified" fund, which allows it to invest
more than 5% of its assets in the obligations of any single issuer, subject only
to certain requirements under tax laws.  Because it can concentrate its
investments in the obligations of a smaller number of issuers, the Portfolio may
be more at risk than a more widely diversified fund to any single economic,
political or regulatory event which harms one or more of those issuers.

RISK/RETURN SUMMARY:  FEE TABLE

Fees and Expenses of the Portfolio

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Portfolio.

Annual Portfolio Operating Expenses (expenses that are deducted from Portfolio
assets)

Advisory fees.................................................. .25%
Other expenses/(a)/............................................ .36%
Total annual Portfolio operating expenses/(a)/................. .61%
_______________

     (a)  BlackRock has voluntarily agreed to cap the "Other expenses" for the
          Portfolio at .12% of average daily net assets and "Total annual
          Portfolio operating expenses" at .37% for the current fiscal year.
          "Other expenses" are based on estimated amounts for the current fiscal
          year.

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

     The Example assumes that you invest $10,000 in the Portfolio 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:

ADDITIONAL MAIN STRATEGIES

IMPORTANT DEFINITIONS

Portfolio Collateral Pool:  The Portfolio relies on monthly reports prepared by
the trustee for each of its CMBS which break out each mortgage loan remaining in
the collateral pool for each CMBS issue by property type.  The percentage for
each property type is calculated by using scheduled principal balances of the
mortgage loans.  The Portfolio then multiplies the value of each of its CMBS as
most recently determined by these percentages reported for each property type to
produce a picture of the total collateral pool (the Portfolio Collateral Pool)
by property type.  Note that the percentages used by the Portfolio in these
calculations:

* are produced by another party and not independently verified by the
  Portfolio;
* are only updated once a month; and
* are based on the outstanding principal amounts, rather than the market values,
  of the underlying mortgage loans.

Property Type:  The collateral underlying each CMBS is classified from
descriptions of each mortgage loan provided by the underwriter or trustee by
property type and reported to the Portfolio.  These property types currently are
broken out as follows:

* multi-family properties and cooperative apartments;
* industrial and warehouse properties;
* office buildings;
* retail space and shopping malls;
* hotels and motels;
* nursing homes and senior living centers;
* restaurants and other franchise businesses;
* hospitals;
* mobile home parks;
* self-storage centers;
* mixed retail and office properties; and
* agricultural properties.


     Diversification.  The Portfolio will seek to diversify its holdings of CMBS
among different types of industries, properties and geographic regions in order
to seek to reduce risk.  Therefore, the Portfolio will not buy a CMBS if:

(a)  The purchase would cause the Portfolio to own more than 25% of any one CMBS
     issue.

(b)  The purchase would cause more than 25% of the Portfolio's net assets to be
     invested in CMBS relating to obligations of a single borrower regarding a
     single asset.

(c)  The purchase would cause more than 10% of the Portfolio's net assets to be
     invested in any one CMBS issue.

(d)  The purchase would cause more than 50% of the Portfolio Collateral Pool to
     consist of a single property type.

(e)  More than 5% of the collateral underlying that issue consists of
     agricultural properties.

(f)  The purchase would cause more than 25% of the Portfolio Collateral Pool to
     consist of properties located in any one state of the United States, except
     that up to 30% of the Portfolio Collateral Pool may consist of properties
     located in California.

(g)  Immediately after that purchase, for any one property type constituting
     collateral underlying that issue:



                                       8
<PAGE>


     (i) If that property type represents more than 25% of the Portfolio
         Collateral Pool, more than 25% of that property type (as a percentage
         of the total amount of that property type in the Portfolio Collateral
         Pool) would be located in any one state of the United States;

         (ii)   If that property type represents more than 20% up to and
                including 25% of the Portfolio Collateral Pool, more than 30% of
                that property type (as a percentage of the total amount of that
                property type in the Portfolio Collateral Pool) would be located
                in any one state of the United States;

        (iii)   If that property type represents more than 15% up to and
                including 20% of the Portfolio Collateral Pool, more than 35% of
                that property type (as a percentage of the total amount of that
                property type in the Portfolio Collateral Pool) would be located
                in any one state of the United States;

         (iv)   If that property type represents more than 10% up to and
                including 15% of the Portfolio Collateral Pool, more than 45% of
                that property type (as a percentage of the total amount of that
                property type in the Portfolio Collateral Pool) would be located
                in any one state of the United States; and

                                       9
<PAGE>


                              (v) If that property type represents 10% or less
                    of the Portfolio Collateral Pool, more than 50% of that
                    property type (as a percentage of the total amount of that
                    property type in the Portfolio Collateral Pool) would
                    be located in any one state of the United States.

     In applying the above diversification limits, securities that are backed by
the same collateral pool are treated as a single issue.

     Ratings of Portfolio Securities.  The weighted average credit quality of
the Portfolio will not be less than BBB+.  U.S. Government Securities are
assigned an AAA (or Aaa) rating.

     To be eligible for purchase by the Portfolio, securities must be U.S.
Government Securities or rated by at least two Rating Agencies.  In
addition:

     1. Except as otherwise provided in 2 and 3 below, the Portfolio will invest
     only in securities that are rated BBB (or Baa) or higher at the time of
     investment by at least two Rating Agencies.  All investments in "interest
     only" securities (which are debt securities that receive only the interest
     payments on an underlying debt) that are components of CMBS must meet these
     ratings requirements.  Securities rated BBB (or Baa) are generally
     considered investment grade, but they also are considered speculative and
     do carry some risks.

     2. The Portfolio may invest up to 10% of its total assets in split rated
     securities.  The Portfolio will consider a security to be split rated if it
     is rated BBB (or Baa) (or higher) by at least one Rating Agency and BB (or
     Ba) by at least one other Rating Agency at the time of investment.  The
     Portfolio may not invest in split rated "interest only" securities.  Split
     rated securities will not be considered to be rated BB (or Ba) for the
     purposes of the limitation referred to in 3 below.

     3. The Portfolio may invest up to an aggregate of 10% of its total assets
     in (i) securities (other than "interest only" securities) rated BB (or Ba)
     at the time of investment by at least two Rating Agencies and (ii)
     "interest only" securities.

                                       10
<PAGE>


     4. The Portfolio may not invest in securities rated lower than BB (or Ba)
     by any Rating Agency nor in any money market instruments which are not
     rated at least A-2 or P-2 by at least two Rating Agencies.

     If any security held by the Portfolio is downgraded by one or more Rating
Agencies such that the Portfolio would not be able at that time to make an
investment in such security, then the Portfolio will sell such security within
60 days after such downgrade.

     Other Main Strategies.  The Portfolio will try to maintain a duration for
its investments of between four and eight years.  Duration is a mathematical
calculation of the average life of a debt security that serves as a measure of
its price risk.  Each year of duration represents an expected 1% change in the
price of a security for every 1% change in interest rates.  Duration,
which measures price sensitivity to interest rate changes, is not necessarily
equal to average maturity.

     The Portfolio may invest in futures, options and interest rate swaps,
commonly known as derivatives.  The Portfolio will use derivatives only for
hedging and to help maintain the interest rate risk of the Portfolio within the
target duration range.

     The Portfolio may purchase securities offered in private placements and
under Rule 144A of the Securities Act of 1933. These securities may be illiquid.
The Portfolio will invest no more than 15% of its net assets in illiquid
securities.

     In determining which Mortgage-Backed Securities the Portfolio will purchase
and when it will sell those securities, the Portfolio's investment adviser will
consider, among other factors, the following: characteristics of the underlying
mortgage loans; characteristics of the underlying properties; terms of the
securities; and structural participants such as administrators and servicers.
In addition, the adviser will interact with rating agencies, review due
diligence done by underwriters and rating agencies, and do its own analysis of
the relative value of the securities and general economic conditions.

     Percentage Limitations.  For the purposes of the foregoing investment
strategies and related percentage limitations, if the Portfolio's asset
composition exceeds 110% of a percentage limitation for any reason, the
Portfolio will take such actions as may be necessary so that within 60 days
after the occurrence of such excess the relevant percentage limitation is again
satisfied.

MANAGEMENT

Adviser

     BlackRock Financial Management, Inc. (BlackRock or the Adviser) serves as
investment adviser to the Portfolio.  BlackRock is an indirect majority-owned
subsidiary of PNC Bank Corp.  BlackRock (formerly BlackRock Financial Management
L.P.) was organized in 1988.   The principal business address of BlackRock is
345 Park Avenue, New York, New York 10154.  BlackRock provides asset management
services with respect to U.S. and foreign fixed income instruments.  As adviser,
BlackRock is responsible for the day-to-day management of the Portfolio, and
generally makes all purchase and sale decisions regarding the investments made
by the Portfolio.  BlackRock also provides research and credit analysis as well
as certain other services.

     Keith Anderson and Mark S. Warner are the persons primarily responsible for
the day-to-day management of the Portfolio's investments.

     Keith Anderson is a Managing Director, Chief Investment Officer, Fixed
Income and Co-head of the Fixed Income Operating Committee at BlackRock.  In
addition, Mr. Anderson co-chairs the Investment Strategy Group and he is a

the government and mortgage sectors.  His areas of expertise include Treasuries,
agencies, futures, options, swaps and a wide range of traditional and non-
traditional mortgage securities.  Mr. Anderson founded BlackRock in 1988 and has
been a co-manager of the Portfolio since its inception.

     Mark S. Warner, CFA, is a Director of BlackRock with primary responsibility
for managing client portfolios.  Mr. Warner specializes in investing in the
commercial mortgage and non-agency residential mortgage sectors.  Mr. Warner has

BlackRock in 1993, Mr. Warner was a Director in the Capital Markets Unit of the
Prudential Mortgage Capital Company.  Mr. Warner joined the Prudential Mortgage
Capital Company in 1987.

     For the services provided and expenses assumed by it, BlackRock is entitled
to receive from the Portfolio a fee computed daily and payable monthly at an
annualized rate of .25% of the Portfolio's average daily net assets.  BlackRock
may waive a portion of its advisory fee.

     The Fund, like any business, could be affected if the computer systems on
which it relies do not properly process information beginning on January 1,
2000.  While Year 2000 issues could have a negative effect on the Fund,
BlackRock is currently working to avoid such problems.  BlackRock is also
working with other service providers and vendors to determine their systems'
ability to handle Year 2000 problems.  There is no guarantee, however, that

                                       12
<PAGE>

systems will work properly on January 1, 2000.  Year 2000 problems may also hurt
issuers whose securities the Portfolio holds or securities markets generally.

Administrators

     BlackRock Advisors, Inc., whose principal business address is 345 Park
Avenue, New York, New York 10154, and PFPC Inc. (PFPC), whose principal business
address is 400 Bellevue Parkway, Wilmington, Delaware 19809, serve as the Fund's
administrators.  BlackRock Advisors, Inc. is an indirect majority-owned
subsidiary, and PFPC is an indirect wholly-owned subsidiary, of PNC Bank Corp.
The administrators generally assist the Fund in all aspects of its
administration and operation, including matters relating to the maintenance of
financial records and fund accounting.

Transfer Agent, Dividend Disbursing Agent and Custodian

     PFPC Trust Company, whose principal business address is 1600 Market Street,
Philadelphia, Pennsylvania 19103, serves as the Fund's custodian and PFPC serves
as the Fund's transfer agent and dividend disbursing agent.

PURCHASE AND REDEMPTION OF SHARES

Distributor

     Shares of the Portfolio are offered on a continuous basis for the Fund by
its distributor, BlackRock Distributors, Inc. (BDI or the Distributor).  The
Distributor is a registered broker/ dealer with principal offices at Four Falls
Corporate Center, 6th Floor, West Conshohocken, PA  19428-2961.

     The Fund has adopted a distribution plan pursuant to Rule 12b-1 (the Plan)
under the Investment Company Act of 1940 (the 1940 Act).  The Fund is not
required or permitted under the Plan to make distribution payments with respect
to the Portfolio's Shares.  However, the Plan permits BDI, BlackRock, PFPC and
other companies that receive fees from the Fund to make payments relating to
distribution and sales support activities out of their past profits or other
sources available to them which, subject to applicable NASD regulations, may
include contributions to various non-cash and cash incentive arrangements to
promote the sale of shares, as well as sponsorship of various educational
programs, sales contests and promotions in which participants may receive
reimbursement of expenses, entertainment and prizes such as travel awards,
merchandise and cash.

Purchase of Shares

     Shares of the Portfolio are offered without a sales load on a continuous
basis to institutional buyers at the net asset value per share of the Portfolio
next determined after an order and payment are received in proper form by PFPC.
Dividends will commence accruing on

                                       13
<PAGE>

Shares once they are "settled" (i.e., once the Portfolio has received payment in
Federal funds or has received securities or other property for the Shares).
Shares may be purchased on any Business Day. A "Business Day" is any weekday
that the New York Stock Exchange (the NYSE) is open for business. Purchase
orders may be made by telephoning PFPC at (800) 441-7379. The Fund may in its
discretion reject any order for Shares.

     Payment for Shares normally must be made in Federal funds or other funds
immediately available to the Fund's custodian.  In addition, BlackRock in its
sole discretion may accept securities or other property as payment for Shares.
Such securities or other property will be valued in accordance with the
procedures described below under "Net Asset Value."  Normally, payments for
Shares should be received by PFPC no later than 12:00 Noon (Eastern Time).

Redemption of Shares

     Redemption orders may be made by telephoning PFPC at (800) 441-7379.
Shares are redeemed at the net asset value per share of the Portfolio next
determined after PFPC's receipt of the redemption request in proper order, and
dividends will not accrue on Shares after the day on which a redemption order
for the Shares settles (i.e., the day the shareholder receives the redemption
proceeds for the Shares).  The Fund, PFPC, BlackRock and the Distributor will
use reasonable procedures to confirm that telephone instructions are genuine.
The Fund and its service providers will not be liable for any loss or expense
for acting upon telephone instructions that they reasonably believed to be
genuine.

     The date on which a redemption request is received will be the redemption
date unless the redemption request specifies a particular date in the future for
its effectiveness.  The Fund will pay all redemption requests made with at least
30 days' advance notice in cash.  If a shareholder is unable to contact PFPC by
telephone, it may also deliver the redemption request to PFPC by mail at 400
Bellevue Parkway, Wilmington, DE 19809.

     The Fund may suspend the right of redemption or postpone the date of
payment upon redemption (as well as suspend the recordation of the transfer of
Shares) for such periods as are permitted under the 1940 Act.  The Fund may also
redeem Shares involuntarily or make payment for redemption in securities or
other property if it appears appropriate to do so in light of the Fund's
responsibilities under the 1940 Act, provided that all involuntary redemptions
will be paid in cash and the Fund's right to redeem Shares in securities or
other property will only apply to those redemption requests not made with at
least 30 days' advance notice.

NET ASSET VALUE

     The net asset value for the Portfolio is calculated as of the close of
trading on the NYSE (currently 4:00 p.m. Eastern Time) on (i) Thursday of each
week (to the extent such day is a Business Day) and (ii) each Business Day on
which a purchase or redemption order is received. Net asset value is calculated
by adding the value of all its securities, cash and other assets, subtracting
the liabilities and dividing by the total number of Shares outstanding.  The net
asset

                                       14
<PAGE>

value per Share of the Portfolio is determined independently of the Fund's other
portfolios. Net asset value will not be calculated on days when the NYSE is not
open for business.

     The value of securities held by the Portfolio is based upon market
quotations or, if market quotations are not readily available, the securities
are valued at fair value as determined in good faith by or under the direction
of the Fund's Board of Trustees.  The Portfolio may use a pricing service, bank
or broker/dealer experienced in such matters to value the Portfolio's
securities.

DIVIDENDS AND DISTRIBUTIONS

     The Portfolio will distribute substantially all of its net investment
income and net realized capital gains, if any, to shareholders.  For dividend
purposes, the Portfolio's investment income available for distribution to
shareholders is reduced by expenses directly attributable to the Portfolio and
the general expenses of the Fund prorated to the Portfolio on the basis of its
relative net assets.  All distributions are paid in cash unless a shareholder
elects to have its distributions reinvested at net asset value in the form of
additional full and fractional Shares of the Portfolio.  Such election, or any
revocation thereof, must be made in writing to PFPC, and will become effective
with respect to dividends paid after its receipt by PFPC.  The net investment
income of the Portfolio is declared daily.  All such dividends are paid not
later than ten days after the end of each month and at the time of redemption of
all of a shareholder's Shares in the Portfolio.  Net realized capital gains, if
any, will be distributed by the Portfolio at least annually.

TAXES

     The following discussion is only a brief summary of some of the important
tax considerations generally affecting the Portfolio and its shareholders and is
not intended as a substitute for careful tax planning.  Accordingly, investors
in the Portfolio should consult their tax advisers with specific reference to
their own tax situation.

     The Portfolio intends to make distributions that may be taxed as ordinary
income and capital gains (which may be taxable at different rates depending on
the length of time the Portfolio holds its assets).  The Portfolio's
distributions, whether received in cash or reinvested in additional shares of
the Portfolio, may be subject to Federal income tax.

     Distributions paid out of the "net capital gain" (the excess of net long-
term capital gain over net short-term capital loss), if any, of the Portfolio
will be taxed to shareholders as long-term capital gain, regardless of the
length of time a shareholder has held his Shares and whether such gain was
reflected in the price paid for the Shares.  All other distributions, to the
extent they are taxable, are taxed to shareholders as ordinary income.

     The Fund will send written notices to shareholders annually regarding the
tax status of distributions made by the Portfolio.  Dividends declared in
October, November or December of any year payable to shareholders of record on a
specified date in those months will be deemed to

                                       15
<PAGE>

have been received by the shareholders on December 31 of such year, provided the
dividends are paid during January of the following year.

     A taxable gain or loss may be realized by a shareholder upon the
redemption, transfer or exchange of Portfolio Shares.

     Future legal developments may affect the tax consequences of investing in
the Portfolio.  Shareholders are urged to consult their tax advisers concerning
the application of state and local income taxes to investments in the Fund which
may differ from the Federal income tax consequences described above.
Shareholders who are nonresident alien individuals, foreign trusts or estates,
foreign corporations or foreign partnerships may be subject to different U.S.
Federal income tax treatment and should consult their tax advisers.

                                 THE FUND

     The Fund was organized as a Massachusetts business trust on December 22,
1988 and is registered under the Investment Company Act of 1940 (the "1940 Act")

                       INVESTMENT OBJECTIVE AND POLICIES

     For a description of the objective and policies of the Portfolio, see
"Risk/Return Summary: Investments and Risks" and "Additional Main Strategies" in
the Prospectus.  In accordance with the applicable provisions of the 1940 Act
the Portfolio will maintain with its custodian a segregated account of liquid
assets to the extent the Portfolio's obligations require segregation from the
use of investment practices listed below.  The following information is provided
for those investors desiring information in addition to that contained in the
Prospectus.

Mortgage-Backed Securities

     Commercial Mortgage-Backed Securities.  Commercial Mortgage-Backed
Securities are generally multi-class debt or pass-through securities backed by a
mortgage loan or pool of mortgage loans secured by commercial property, such as
industrial and warehouse properties, office buildings, retail space and shopping
malls, multi-family properties and cooperative apartments, hotels and motels,
nursing homes, hospitals, senior living centers,  restaurants, mobile home parks
and self-storage centers.  The commercial mortgage loans that underlie
Commercial Mortgage-Backed Securities have certain distinct characteristics.
Commercial mortgage loans are generally not amortizing or not fully amortizing.
At their maturity date, repayment of the remaining principal balance or
"balloon" is due and is repaid through the attainment of an additional loan or
sale of the property.  Unlike most single family residential mortgages,
commercial real property loans often contain provisions which substantially
reduce the likelihood that such securities will be prepaid.  The provisions
generally impose significant prepayment penalties on loans and, in some cases,
there may be prohibitions on principal prepayments for several years following
origination.  This difference in prepayment exposure is significant due to
extraordinarily high levels of refinancing of traditional residential mortgages
experienced over the past years as mortgage rates reached 25 year lows.  Assets
underlying Commercial Mortgage-Backed Securities may relate to only a few
properties or to a single property.  See "Risk Factors Relating to Mortgage-
Backed Securities."

                                      -2-
<PAGE>

     Commercial Mortgage-Backed Securities have been issued in public and
private transactions by a variety of public and private issuers.  Non-
governmental entities that have issued or sponsored Commercial Mortgage-Backed
Securities offerings include owners of commercial properties, originators of and
investors in mortgage loans, savings and loan associations, mortgage banks,
commercial banks, insurance companies, investment banks and special purpose
subsidiaries of the foregoing.  The Portfolio may from time to time purchase
Commercial Mortgage-Backed Securities directly from issuers in negotiated
transactions or from a holder of such Commercial Mortgage-Backed Securities in
the secondary market.

     Commercial Mortgage-Backed Securities generally are structured to protect
the senior class investors against potential losses on the underlying mortgage
loans.  This is generally provided by the subordinated class investors, which
may be included in the Portfolio, by taking the first loss if there are defaults
on the underlying commercial mortgage loans.  Other protection, which may
benefit all of the classes, including the subordinated classes in which the
Portfolio intends to invest, may include issuer guarantees, reserve funds,
additional subordinated securities, cross-collateralization, over-
collateralization and the equity investors in the underlying properties.

     By adjusting the priority of interest and principal payments on each class
of a given Commercial Mortgage-Backed Security, issuers are able to issue senior
investment grade securities and lower rated or non-rated subordinated securities
tailored to meet the needs of sophisticated institutional investors.  In
general, subordinated classes of Commercial Mortgage-Backed Securities are
entitled to receive repayment of principal only after all required principal
payments have been made to more senior classes and have subordinate rights as to
receipt of interest distributions.  Such subordinated classes are subject to a
substantially greater risk of nonpayment than are senior classes of Commercial
Mortgage-Backed Securities.  Even within a class of subordinate securities, most
Commercial Mortgage-Backed Securities are structured with a hierarchy of levels
(or "loss positions").  Loss positions are the order in which non-recoverable
losses of principal are applied to the securities within a given structure.  For
instance, a first loss subordinate security will absorb any principal losses
before any higher loss position subordinate security.  This type of structure
allows a number of classes of securities to be created with varying degrees of
credit exposure, prepayment exposure and potential total return.

     Subordinated classes of Commercial Mortgage-Backed Securities have more
recently been structured to meet specific investor preferences and issuer
constraints and have different priorities for cash flow and loss absorption.  As
previously discussed, from a credit perspective, they are structured to absorb
any credit-related losses prior to the senior class.  The principal cash flow
characteristics of subordinated classes are designed to be among the most stable
in the Mortgage-Backed Securities market, the probability of prepayment being
much lower than with traditional Residential Mortgage-Backed Securities.  This
characteristic is primarily due to the structural feature that directs the
application of principal payments first to the senior classes until

                                      -3-
<PAGE>

they are retired before the subordinated classes receive any prepayments. While
this serves to enhance the credit protection of the senior classes, it produces
subordinated classes with more stable average lives. Subject to the applicable
provisions of the 1940 Act and to the terms of the Prospectus, there are no
limitations on the classes of Commercial Mortgage-Backed Securities in which the
Portfolio may invest. Accordingly, in certain circumstances, the Portfolio may
recover proportionally less of its investment in a Commercial Mortgage-Backed
Security than the holders of more senior classes of the same Commercial
Mortgage-Backed Security.

     The rating assigned to a given issue and class of Commercial Mortgage-
Backed Securities is a product of many factors, including the structure of the
security, the level of subordination, the quality and adequacy of the
collateral, and the past performance of the originators and servicing companies.
The rating of any Commercial Mortgage-Backed Security is determined to a
substantial degree by the debt service coverage ratio (i.e., the ratio of
current net operating income from the commercial properties, in the aggregate,
to the current debt service obligations on the properties) and the LTV ratio of
the pooled properties.  The amount of the securities issued in any one rating
category is determined by the rating agencies after a rigorous credit rating
process which includes analysis of the issuer, servicer and property manager, as
well as verification of the LTV and debt service coverage ratios.  LTV ratios
may be particularly important in the case of commercial mortgages because most
commercial mortgage loans provide that the lender's sole remedy in the event of
a default is against the mortgaged property, and the lender is not permitted to
pursue remedies with respect to other assets of the borrower.  Accordingly,
loan-to-value ratios may, in certain circumstances, determine the amount
realized by the holder of the Commercial Mortgaged-Backed Security.

     Residential Mortgage-Backed Securities.  The Portfolio also expects to
invest in Residential Mortgage-Backed Securities that are Mortgage-Backed
Securities representing participation interests in pools of single-family
residential mortgage loans originated by private mortgage originators.
Traditionally, Residential Mortgage-Backed Securities were issued by
governmental agencies such as Fannie Mae, Freddie Mac and Ginnie Mae.  The
Portfolio intends to invest in those securities issued by nongovernmental
agencies as well as governmental agencies.  Nongovernmental entities that have
issued or sponsored Residential Mortgage-Backed Securities offerings include
savings and loan associations, mortgage banks, insurance companies, investment
banks and special purpose subsidiaries of the foregoing.  Residential Mortgage-
Backed Securities, similar to Commercial Mortgage-Backed Securities, have been
issued using a variety of structures, including multi-class structures featuring
senior and subordinated classes.

     While single-family residential loans do not typically have prepayment
penalties or restrictions, as commercial mortgage loans often do, Residential
Mortgage-Backed Securities are often structured so that subordinated classes may
be locked out of prepayments for a period of time.  However, in a period of
extremely rapid prepayments, during which senior classes may be retired faster
than expected, the subordinated classes may receive unscheduled payments of

                                      -4-
<PAGE>

principal and would have average lives that, while longer than the average lives
of the senior classes, would be shorter than originally expected.

     The types of agency and non-agency Commercial and Residential Mortgage-
Backed Securities in which the Portfolio may invest shall include, but not be
limited to, the following securities:

     Adjustable Rate Mortgage Securities.  Adjustable rate mortgage securities
are pass-through mortgage securities collateralized by mortgages with adjustable
rather than fixed rates ("ARMs").  ARMs eligible for inclusion in a mortgage
pool generally provide for a fixed initial mortgage interest rate for either the
first three, six, twelve, thirteen, thirty-six or sixty scheduled monthly
payments.  Thereafter, the interest rates are subject to periodic adjustment
based on changes to a designated benchmark index.

     ARMs contain maximum and minimum rates beyond which the mortgage interest
rate may not vary over the lifetime of the mortgage.  In addition, certain ARMs
provide for additional limitations on the maximum amount by which the mortgage
interest rate may adjust for any single adjustment period.  Alternatively,
certain ARMs contain limitations on changes in the required monthly payment.  In
the event that a monthly payment is not sufficient to pay the interest accruing
on an ARM, any such excess interest is added to the principal balance of the
mortgage loan, which is repaid through future monthly payments.  If the monthly
payment for such an instrument exceeds the sum of the interest accrued at the
applicable mortgage interest rate and the principal payment required at such
point to amortize the outstanding principal balance over the remaining term of
the loan, the excess is utilized to reduce the then outstanding principal
balance of the ARM.

     Collateralized Mortgage Obligations and Multi-Class Pass-Through
Securities.  Collateralized mortgage obligations or "CMOs" are debt obligations
collateralized by mortgage loans or mortgage pass-through securities.
Typically, CMOs are collateralized by GNMA, FNMA or FHLMC certificates, but also
may be collateralized by whole loans or private mortgage pass-through securities
(collectively, "Mortgage Assets").  Multi-class pass-through securities are
equity interests in a trust composed of Mortgage Assets.  Unless the context
indicates otherwise, all references herein to CMOs include multi-class pass-
through certificates.  Payments of principal of and interest on the Mortgage
Assets, and any reinvestment income thereon, provide the funds to pay debt
service on the CMOs or make scheduled distributions on the multi-class pass-
through securities.  CMOs may be issued by agencies or instrumentalities of the
U.S. Government, or by private originators of, or investors in, mortgage loans,
including depository institutions, mortgage banks, investment banks and special
purpose subsidiaries of the foregoing.  The issuer of CMOs or multi-class pass-
through securities may elect to be treated as a Real Estate Mortgage Investment
Conduit ("REMIC").

                                      -5-
<PAGE>

     In a CMO, a series of bonds or certificates is issued in multiple classes.
Each class of CMOs, often referred to as a "tranche," is issued at a specific
fixed or floating coupon rate and has a stated maturity or final distribution
date. Principal prepayments on the Mortgage Assets may cause the CMOs to be
retired substantially earlier than their stated maturities or final distribution
dates. Interest is paid or accrues on all classes of the CMOs on a monthly,
quarterly or semi-annual basis. The principal of and interest on the Mortgage
Assets may be allocated among the several classes of a CMO series in a number of
different ways. Generally, the purpose of the allocation of the cash flow of a
CMO to the various classes is to obtain a more predictable cash flow to the
individual tranches than exists with the underlying collateral of the CMO. As a
general rule, the more predictable the cash flow is on a CMO tranche, the lower
the anticipated yield will be on that tranche at the time of issuance relative
to prevailing market yields on Mortgage-Backed Securities.

     The Portfolio also may invest in, among other things, parallel-pay CMOs and
Planned Amortization Class CMOs ("PAC Bonds").  Parallel-pay CMOs are structured
to provide payments of principal on each payment date to more than one class.
These simultaneous payments are taken into account in calculating the stated
maturity date or final distribution date of each class, which, as with other CMO
structures, must be retired by its stated maturity date or final distribution
date but may be retired earlier.  PAC Bonds generally require payments of a
specified amount of principal on each payment date.  PAC Bonds are parallel-pay
CMOs with the required principal payment on such securities having the highest
priority after interest has been paid to all classes.

     The Portfolio may invest in CMO residuals to the extent the Adviser
identifies any which satisfy the rating criteria in the Prospectus.  The
residual in a CMO structure generally represents the interest in any excess cash
flow remaining after making required payments of principal of and interest on
the CMOs and related administrative expenses of the issuer.

     Mortgage-Related Securities Issued by U.S. Government Agencies and
Instrumentalities.  The Portfolio may invest in Mortgage-Backed Securities
issued by agencies or instrumentalities of the U.S. Government including GNMA,
FNMA and FHLMC.  The U.S. Government or the issuing agency guarantees the
payment of interest and principal on these securities.  However, the guarantees
do not extend to the securities' yield or value, nor do the guarantees extend to
the yield or value of the Portfolio's shares.  These securities are in most
cases "pass-through" instruments, through which the holder receives a share of
all interest and principal payments from the mortgages underlying the security,
net of certain fees.

     Private Mortgage Pass-Through Securities.  Private mortgage pass-through
securities are structured similarly to GNMA, FNMA and FHLMC mortgage pass-
through securities and are issued by originators of and investors in mortgage
loans, including depository institutions, mortgage banks, investment banks and
special purpose subsidiaries of the foregoing.  These securities usually are
backed either by GNMA, FNMA or FHLMC certificates or by a pool of fixed rate or
adjustable rate mortgage loans.  Securities which are backed by a pool of fixed
rate

                                      -6-
<PAGE>

or adjustable rate mortgage loans generally are structured with one or more
types of credit enhancement.

     GNMA Certificates.  GNMA is a wholly-owned corporate instrumentality of the
United States within the Department of Housing and Urban Development.  The
National Housing Act of 1934, as amended (the "Housing Act"), authorized GNMA to
guarantee the timely payment of the principal of and interest on certificates
that are based on and backed by a pool of mortgage loans insured by the Federal
Housing Administration under the Housing Act, or Title V of the Housing Act of
1949 ("FHA Loans"), or guaranteed by the Veterans' Administration under the
Servicemen's Readjustment Act of 1944, as amended ("VA Loans"), or by pools of
other eligible mortgage loans.  The Housing Act provides that the full faith and
credit of the U.S. Government is pledged to the payment of all amounts that may
be required to be paid under the guarantee.  In order to meet its obligations
under such guarantee, GNMA is authorized to borrow from the U.S. Treasury with
no limitations as to amount.

     The GNMA certificates will represent a pro-rata interest in one or more
pools of the following types of mortgage loans: (i) fixed rate level payment
mortgage loans; (ii) fixed rate graduated payment mortgage loans; (iii) fixed
rate growing equity mortgage loans; (iv) fixed rate mortgage loans secured by
manufactured (mobile) homes; (v) mortgage loans on multi-family residential
properties under construction; (vi) mortgage loans on completed multi-family
projects; (vii) fixed rate mortgage loans as to which escrowed funds are used to
reduce the borrower's monthly payments during the early years of the mortgage
loans ("buydown" mortgage loans); (viii) mortgage loans that provide for
adjustments in payments based on periodic changes in interest rates or in other
payment terms of the mortgage loans; and (ix) mortgage-backed serial notes.  All
of these mortgage loans will be FHA Loans or VA Loans and, except as otherwise
specified above, will be fully-amortizing loans secured by first liens on one-to
four-family housing units.

     FNMA Certificates.  FNMA is a federally chartered and privately owned
corporation organized and existing under the Federal National Mortgage
Association Charter Act.  FNMA was originally established in 1938 as a U.S.
Government agency to provide supplemental liquidity to the mortgage market and
was transformed into a stockholder owned and privately managed corporation by
legislation enacted in 1968.  FNMA provides funds to the mortgage market
primarily by purchasing home mortgage loans from local lenders, thereby
replenishing their funds for additional lending.  FNMA acquires funds to
purchase home mortgage loans from many capital market investors that may not
ordinarily invest in mortgage loans directly, thereby expanding the total amount
of funds available for housing.

     Each FNMA certificate will entitle the registered holder thereof to receive
amounts representing such holder's pro-rata interest in scheduled principal
payments and interest payments (at such FNMA certificate's pass-through rate,
which is net of any servicing and guarantee fees

                                      -7-
<PAGE>

on the underlying mortgage loans), and any principal prepayments on the mortgage
loans in the pool represented by such FNMA certificate and such holder's
proportionate interest in the full principal amount of any foreclosed or
otherwise finally liquidated mortgage loan. The full and timely payment of
principal of and interest on each FNMA certificate will be guaranteed by FNMA,
which guarantee is not backed by the full faith and credit of the U.S.
Government.

     Each FNMA certificate will represent a pro rata interest in one or more
pools of FHA Loans, VA Loans or conventional mortgage loans (i.e., mortgage
loans that are not insured or guaranteed by any governmental agency) of the
following types: (i) fixed rate level payment mortgage loans; (ii) fixed rate
graduated payment mortgage loans; and (iii) adjustable rate mortgage loans.

     FHLMC Certificates.  FHLMC is a corporate instrumentality of the United
States created pursuant to the Emergency Home Finance Act of 1970, as amended
(the "FHLMC Act").  FHLMC was established primarily for the purpose of
increasing the availability of mortgage credit for the financing of needed
housing.  The principal activity of FHLMC currently consists of the purchase of
first lien, conventional, residential mortgage loans and participation interests
in such mortgage loans and the resale of the mortgage loans so purchased in the
form of mortgage securities, primarily FHLMC certificates.

     FHLMC guarantees to each registered holder of a FHLMC certificate the
timely payment of interest at the rate provided for by such FHLMC certificate,
whether or not received.  FHLMC also guarantees to each registered holder of a
FHLMC certificate ultimate collection of all principal of the related mortgage
loans, without any offset or deduction, but does not, generally, guarantee the
timely payment of scheduled principal.  FHLMC may remit the amount due on
account of its guarantee of collection of principal at any time after default on
an underlying mortgage loan, but not later than 30 days following (i)
foreclosure sale, (ii) payment of a claim by any mortgage insurer or (iii) the
expiration of any right of redemption, whichever occurs later, but in any event
no later than one year after demand has been made upon the mortgagor for
accelerated payment of principal.  The obligations of FHLMC under its guarantee
are obligations solely of FHLMC and are not backed by the full faith and credit
of the U.S. Government.

     FHLMC certificates represent a pro rata interest in a group of mortgage
loans (a "FHLMC certificate group") purchased by FHLMC.  The mortgage loans
underlying the FHLMC certificates will consist of fixed rate or adjustable rate
mortgage loans with original terms to maturity of between ten and thirty years,
substantially all of which are secured by first liens on one- to four-family
residential properties or multifamily projects.  Each mortgage loan must meet
the applicable standards set forth in the FHLMC Act.  A FHLMC certificate group
may include whole loans, participation interests in whole loans and undivided
interests in whole loans and participations comprising another FHLMC certificate
group.

                                      -8-
<PAGE>

     Interest Only Securities.  The Portfolio may purchase stripped mortgage or
"interest only" securities which are derivative multiclass mortgage securities.
Stripped mortgage securities may be issued by agencies or instrumentalities of
the U.S. government, or by private originators of, or investors in, mortgage
loans, including savings and loan associations, mortgage banks, commercial
banks, investment banks and special purpose subsidiaries of the foregoing. These
securities have greater volatility than other types of mortgage securities.
Although these securities are purchased and sold by institutional investors
through several investment banking firms acting as brokers or dealers, the
market for such securities has not yet been fully developed. Accordingly,
stripped mortgage securities are generally illiquid.

     Stripped mortgage securities are structured with two or more classes of
securities that receive different proportions of the interest and principal
distributions on a pool of mortgage assets. A common type of stripped mortgage
security will have at least one class receiving only a small portion of the
interest and a larger portion of the principal from the mortgage assets, while
the other class will receive primarily interest and only a small portion of the
principal. In the most extreme case, one class will receive all of the interest
("IO" or interest-only), while the other class will receive all of the principal
("PO" or principal-only class). The yield to maturity on IOs, POs and other
Mortgage-Backed Securities that are purchased at a substantial premium or
discount generally are extremely sensitive not only to changes in prevailing
interest rates but also to the rate of principal payments (including
prepayments) on the related underlying mortgage assets, and a rapid rate of
principal payments may have a material adverse effect on such securities' yield
to maturity. If the underlying mortgage assets experience greater than
anticipated prepayments of principal, the Portfolio may fail to fully recoup its
initial investment in these securities even if the securities have received the
highest rating by a nationally recognized statistical rating organizations.

     Miscellaneous. The Portfolio may from time to time purchase in the
secondary market certain mortgage pass-through securities packaged and master
serviced by PNC Mortgage Securities Corp. ("PNC Mortgage") or Midland Loan
Services, Inc. ("Midland") (or Sears Mortgage if PNC Mortgage succeeded to
rights and duties of Sears Mortgage) or mortgage-related securities containing
loans or mortgages originated by PNC Bank or its affiliates.  It is possible
that under some circumstances, PNC Mortgage, Midland or their 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.

     The Portfolio will not purchase Mortgage-Backed Securities in the secondary
market from broker-dealers who are affiliated with PNC Bank.  In addition, the
Portfolio will not purchase Mortgage-Backed Securities in the primary market
containing loans or mortgages originated by PNC Bank or its affiliates.

<PAGE>

Lower Rated Securities

     The Mortgage-Backed Securities in which the Portfolio may invest may be
lower rated (i.e., have a credit quality below investment grade) subordinated
classes.  Investments in such lower rated securities are subject to special
risks, including a greater risk of loss of principal and non-payment of
interest.  An investor should carefully consider the following factors before
purchasing shares of the Portfolio.   The Portfolio will maintain a dollar-
weighted average credit quality of no less than BBB+.  In order to calculate the
average credit quality of the Portfolio, the Portfolio will assign sequential
numbers to each of the rating categories, multiply the value of each instrument
by the rating equivalent number assigned to its lowest rating, sum all of such
products, divide the aggregate by the net asset value of the Portfolio and
convert the number back to its equivalent rating symbol.

     Generally, lower rated securities offer a higher return potential than
higher rated securities but involve greater volatility of price and greater risk
of loss of income and principal, including the possibility of default or
bankruptcy of the issuers of such securities.  Lower rated securities will
likely have large uncertainties or major risk exposure to adverse conditions and
are predominately speculative.  The occurrence of adverse conditions and
uncertainties would likely reduce the value of securities held by the Portfolio,
with a commensurate effect on the value of the Portfolio's shares.  While the
market values of lower rated securities tend to react less to fluctuations in
interest rate levels than do those of higher rated securities, the market values
of certain of these securities also tend to be more sensitive to changes in
economic conditions than higher rated securities.  In addition, lower rated
securities generally present a higher degree of credit risk.  The Portfolio may
incur additional expenses to the extent that it is required to seek recovery
upon a default in the payment of principal or interest on its portfolio
holdings.

     Securities which are rated BB by Standard & Poor's Ratings Group ("S&P"),
Duff & Phelps Inc. ("D&P") and Fitch Investors Service ("Fitch") and Ba by
Moody's Investors Service, Inc. ("Moody's")  have speculative characteristics
with respect to capacity to pay interest and repay principal.  A general
description of the bond ratings of Moody's, S&P, D&P and Fitch is set forth in
Appendix A hereto.

     The rating assigned by a rating agency evaluates the safety of a non-
investment grade security's principal and interest payments, but does not
address market value risk.  Ratings may from time to time change, positively or
negatively, to reflect developments regarding the issuer's financial condition.
Because such ratings of the ratings agencies may not always reflect current
conditions and events, in addition to using recognized rating agencies and other
sources, the Adviser performs its own analysis of the issuers whose non-
investment grade securities the Portfolio holds.  Because of this, the
Portfolio's performance may depend more on the Adviser's own credit analysis
than in the case of mutual funds investing in higher-rated securities.

Types of Credit Enhancement

     Mortgage-Backed Securities are often backed by a pool of assets
representing the obligations of a number of different parties.  To lessen the
effect of failures by obligors on underlying assets to make payments, those
securities may contain elements of credit support, which fall into two
categories: (i) liquidity protection and (ii) protection against losses
resulting from ultimate default by an obligor on the underlying assets.
Liquidity protection refers to the provision of advances, generally by the
entity administering the pool of assets, to ensure that the receipt of payments
on the underlying pool occurs in a timely fashion.  Protection against losses
resulting from default ensures ultimate payment of the obligations on at least a
portion of the assets in the pool.  This protection may be provided through
guarantees, insurance policies or letters of credit obtained by the issuer or
sponsor from third parties, through various means of structuring other more
subordinate securities in the transaction or through a combination of such
approaches.  The Portfolio will not pay any additional fees for credit support,
although the existence of credit support may increase the price of a security.

     Examples of credit support arising out of the structure of the transaction
include "senior-subordinated securities" (multiple class securities with one or
more classes subordinate to other classes as to the payment of principal thereof
and interest thereon, with the result that defaults on the underlying assets are
borne first by the holders of the subordinated class), creation of "reserve
funds" (where cash or investments, sometimes funded from a portion of the
payments on the underlying assets, are held in reserve against future losses)
and "overcollateralization" (where the scheduled payments on, or the principal
amount of, the underlying assets exceeds that required to make payment of the
securities and pay any servicing or other fees).  The degree of credit support
provided for each issue is generally based on historical information respecting
the level of credit risk associated with the underlying assets.  Delinquencies
or losses in excess of those anticipated could adversely affect the return on an
investment in such issue.

Risk Factors Relating to Mortgage-Backed Securities

     The yield characteristics of Mortgage-Backed Securities differ from
traditional debt securities.  Among the major differences are that interest and
principal payments are made more frequently, usually monthly, and that principal
may be prepaid at any time because the underlying mortgage loans or other assets
generally may be prepaid at any time.  As a result, if the Portfolio purchases
such a security at a premium, a prepayment rate that is faster than expected
will reduce yield to maturity, while a prepayment rate that is slower than
expected will have the opposite effect of increasing yield to maturity.
Alternatively, if the Portfolio purchases these securities at a discount, faster
than expected prepayments will increase, while slower than expected prepayments
will reduce, yield to maturity.

     Although the extent of prepayments on a pool of mortgage loans depends on
various economic and other factors, as a general rule prepayments on fixed rate
mortgage loans will

                                      -11-
<PAGE>

increase during a period of falling interest rates and decrease during a period
of rising interest rates.  Accordingly, amounts available for reinvestment by
the Portfolio are likely to be greater during a period of declining interest
rates and, as a result, likely to be reinvested at lower interest rates than
during a period of rising interest rates.  Mortgage-Backed Securities may
decrease in value as a result of increases in interest rates and may benefit
less than other fixed income securities from declining interest rates because of
the risk of prepayment.  The markets for Mortgage-Backed Securities may be more
illiquid than those of other securities.

     Investments in Commercial Mortgage-Backed Securities involve the credit
risks of delinquency and default.  Delinquency refers to interruptions in the
payment of interest and principal.  Default refers to the potential for
unrecoverable principal loss from the sale of foreclosed property.  These risks
include the risks inherent in the commercial mortgage loans which support such
Commercial Mortgage-Backed Securities and the risks associated with direct
ownership of real estate.  This may be especially true in the case of Commercial
Mortgage-Backed Securities secured by, or evidencing an interest in, a
relatively small or less diverse pool of commercial mortgage loans.  The factors
contributing to these risks include the effects of general and local economic
conditions on real estate values, the conditions of specific industry segments,
the ability of tenants to make lease payments and the ability of a property to
attract and retain tenants, which in turn may be affected by local conditions
such as oversupply of space or a reduction of available space, the ability of
the owner to provide adequate maintenance and insurance, energy costs,
government regulations with respect to environmental, zoning, rent control and
other matters, and real estate and other taxes.

     While the credit quality of the Commercial Mortgage-Backed Securities in
which the Portfolio may invest will reflect the perceived likelihood of future
cash flows to meet operating expenses and cash flow requirements, the underlying
commercial properties may not be able to continue to generate income to meet
their operating expenses and cash flow requirements (mainly debt service, lease
payments, capital expenditures, taxes, maintenance, insurance and tenant
improvements) as a result of any of the factors mentioned above.  Consequently,
the obligors under commercial mortgages may be unable to make payments of
interest in a timely fashion, increasing the risk of default on a related
Commercial Mortgage-Backed Security.  In addition, the repayment of the
commercial mortgage loans underlying Commercial Mortgage-Backed Securities will
typically depend upon the future availability of financing and the stability of
real estate property values.

     The commercial mortgage loans that underlie Commercial Mortgage-Backed
Securities have certain distinct characteristics.  Commercial mortgage loans are
generally not amortizing or not fully amortizing.  At their maturity date,
repayment of the remaining principal balance or "balloon" is due and is repaid
through the attainment of an additional loan or sale of the property.  Most
commercial mortgage loans are nonrecourse obligations of the borrower, meaning
that the sole remedy of the lender in the event of a default is to foreclose
upon the collateral.  As a result, in the event of default by a borrower,
recourse may be had only against the specified property

                                      -12-
<PAGE>

pledged to secure the loan and not against the borrower's other assets.  If
borrowers are not able or willing to refinance or dispose of the property to pay
the principal balance due at maturity, payments on the subordinated classes of
the related Commercial Mortgage-Backed Security are likely to be adversely
affected.  The ultimate extent of the loss, if any, to the subordinated classes
may only be determined after the foreclosure of the mortgage encumbering the
property and, if the mortgagee takes title to the property, upon liquidation of
the property.  Factors such as the title of the property, its physical condition
and financial performance, as well as governmental disclosure requirements with
respect to the condition of the property, may make a third party unwilling to
purchase the property at a foreclosure sale or for a price sufficient to satisfy
the obligations with respect to the related Commercial Mortgage-Backed
Securities.  The condition of a property may deteriorate during foreclosure
proceedings.  Certain obligors on underlying mortgages may become subject to
bankruptcy proceedings, in which case the amount and timing of amounts due under
the related Commercial Mortgage-Backed Securities may be materially adversely
affected.

     In general, any losses on a given Commercial Mortgage-Backed Security will
be absorbed first by the equity holder, then by a cash reserve fund or letter of
credit, if any, and then by the "first loss" subordinated security to the extent
of its principal balance.  Because the Portfolio intends to invest in
subordinated classes of Commercial Mortgage-Backed Securities, there can be no
assurances that in the event of default and the exhaustion of equity support,
the reserve fund and any debt classes junior to those in which the Portfolio
invests, the Portfolio will be able to recover all of its investment in the
securities it purchases.  In addition, if the underlying mortgage portfolio has
been overvalued by the originator, or if mortgage values subsequently decline,
the Portfolio may hold the "first loss" position in certain Commercial Mortgage-
Backed Securities ahead of the more senior debt holders, which may result in
significant losses.  Many of the lower-rated Commercial Mortgage-Backed
Securities are subject to less prepayment risk than in the case of Residential
Mortgage-Backed Securities because of structural features of the underlying
mortgage loans and the fact that they are entitled to repayment only after more
senior classes are paid.

     Investments in Residential Mortgage-Backed Securities involve the credit
risks that affect interest and principal cash flows similar to the credit risks
of Commercial Mortgage-Backed Securities discussed above, as well as the
prepayment risks associated with the possibility that prepayments of principal
generally may be made at any time without penalty.  Prepayment rates are
influenced by changes in current interest rates and a variety of economic,
geographic, social and other factors.  Changes in the rate of prepayments on a
Residential Mortgage-Backed Security may change the yield to maturity of the
security and amounts available for reinvestment from such securities by the
Portfolio are likely to be greater during periods of relatively low or declining
interest rates and therefore are likely to be reinvested at lower interest rates
than during a period of relatively high interest rates.  This prepayment effect
has been particularly pronounced in recent years as borrowers have refinanced
higher interest rate mortgages into lower interest rate mortgages available in
the marketplace.  Because the Portfolio expects to

                                      -13-
<PAGE>

invest in subordinated Residential Mortgage-Backed Securities, the
prioritization of cash flows from mortgages under the Residential Mortgage-
Backed Securities in favor of the senior classes generally reduces this
prepayment risk.

Risk Factors Relating to Lower Rated Securities

     An investor should recognize that the lower-rated Commercial and
Residential Mortgage-Backed Securities in which the Portfolio may invest have
speculative characteristics.  The prices of lower credit quality securities,
which are commonly referred to as "junk bonds," have been found to be less
sensitive to interest rate changes than more highly rated investments, but more
sensitive to adverse economic downturns or individual issuer developments.
Securities rated BB/Ba can be regarded as speculative.  A projection of an
economic downturn or the advent of a recession, for example, could cause a
decline in the price of lower credit quality securities because the advent of a
recession could lessen the ability of obligors of mortgages underlying
Commercial Mortgage-Backed Securities and Residential Mortgage-Backed Securities
to make principal and interest payments.  In such event, existing credit
supports and any first loss positions may be insufficient to protect against
loss of principal.

     Issuers of lower rated securities are often in the growth stage of their
development and/or involved in a reorganization or takeover.  The companies are
often highly leveraged (have a significant amount of debt relative to
shareholders' equity) and may not have available to them more traditional
financing methods, thereby increasing the risk associated with acquiring these
types of securities.  In some cases, obligations with respect to lower rated
securities are subordinated to the prior repayment of senior indebtedness, which
will potentially limit a Portfolio's ability to fully recover principal or to
receive interest payments when senior securities are in default.

     The secondary markets for lower rated securities are not as liquid as the
secondary markets for higher rated securities.  The secondary markets for lower
rated securities are concentrated in relatively few market makers and
participants in the markets are mostly institutional investors, including
insurance companies, banks, other financial institutions and mutual funds.  In
addition, the trading volume for these securities is generally lower than that
for higher rated securities and the secondary markets could contract under
adverse market or economic conditions independent of any specific adverse
changes in the condition of a particular issuer.  Under certain economic and/or
market conditions, the Portfolio may have difficulty disposing of certain lower
rated securities due to the limited number of investors in that sector of the
market.  An illiquid secondary market may adversely affect the market price of
the security, which may result in increased difficulty selling the particular
issue and obtaining accurate market quotations on the issue when valuing a
Portfolio's assets.  Market quotations on lower rated securities are available
only from a limited number of dealers, and such quotations may not be the actual
prices available for a purchase or sale.

                                      -14-
<PAGE>

     The markets for lower rated securities may react strongly to adverse news
about an issuer or the economy, or to the perception or expectation of adverse
news, whether or not it is based on fundamental analysis.  Additionally, prices
for these securities may be affected by legislative and regulatory developments.
These developments could adversely affect the Portfolio's net asset value and
investment practices, the secondary market, the financial condition of issuers
of these securities and the value and liquidity of outstanding securities,
especially in a thinly traded market.  For example, federal legislation
requiring the divestiture by federally insured savings and loan associations of
their investments in lower rated bonds and limiting the deductibility of
interest by certain corporate issuers of these bonds adversely affected the
market in recent years.

     When the secondary market for lower rated securities becomes more illiquid,
or in the absence of readily available market quotations for such securities,
the relative lack of reliable objective data makes it more difficult to value
the Portfolio's securities, and judgment plays a more important role in
determining such valuations.  Increased illiquidity, in combination with the
relative youth and growth of the market for such securities, also may affect the
ability of the Portfolio to dispose of such securities at a desirable price.
Additionally, if the secondary markets for lower rated securities contract due
to adverse economic conditions or for other reasons, certain of the Portfolio's
liquid securities may become illiquid and the proportion of the Portfolio's
assets invested in illiquid securities may significantly increase.

     The costs attributable to investing in lower rated securities are usually
higher for several reasons, such as higher investment research costs and higher
commission costs.


Other Investment Practices

     Duration. The Portfolio will try to maintain a duration for its investments
of between four and eight years.  Duration is a mathematical calculation of the
average life of a debt security that serves as a measure of its price risk.
Each year of duration represents an expected 1% change in the price of a
security for every 1% change in interest rates.  Duration, which measures price
sensitivity to interest rate changes, is not necessarily equal to average
maturity.

     Certain Management Techniques.  The Portfolio may purchase and sell futures
contracts, enter into various interest rate transactions such as swaps, caps and
floors and may purchase and sell exchange-listed and over-the-counter put and
call options on securities, financial indices and futures contracts
(collectively, "Additional Investment Management Techniques").  These Additional
Investment Management Techniques may be used for duration management and other
risk management to attempt to protect against possible changes in the market
value of the Portfolio resulting from trends in the debt securities markets and
changes in interest rates, to protect the Portfolio's unrealized gains in the
value of its securities holdings, to facilitate the sale of such securities for
investment purposes and to establish a position in the securities markets as a
temporary substitute for purchasing particular securities.  There is no

                                      -15-
<PAGE>

particular strategy that requires use of one technique rather than another as
the decision to use any particular strategy or instrument is a function of
market conditions and the composition of the portfolio.  See Appendix B "General
Characteristics and Risks of Additional Investment Management Techniques."

     Additional Investment Management Techniques present certain risks.  With
respect to hedging and risk management, the variable degree of correlation
between price movements of hedging instruments and price movements in the
position being hedged creates the possibility that losses on the hedge may be
greater than gains in the value of the Portfolio's position.  In addition,
certain instruments and markets may not be liquid in all circumstances.  As a
result, in volatile markets, the Portfolio may not be able to close out a
transaction without incurring losses substantially greater than the initial
deposit.  Although the contemplated use of these instruments predominantly for
hedging should tend to minimize the risk of loss due to a decline in the value
of the position, at the same time they tend to limit any potential gain which
might result from an increase in the value of such position.  The ability of the
Portfolio to successfully utilize Additional Investment Management Techniques
will depend on the ability of BlackRock Financial Management, Inc. ("BlackRock"
or the "Adviser") to predict pertinent market movements and sufficient
correlations, which cannot be assured.  Finally, the daily deposit requirements
in futures contracts that the Portfolio has sold create an ongoing greater
potential financial risk than do options transactions, where the exposure is
limited to the cost of the initial premium.  Losses due to the use of Additional
Investment Management Techniques will reduce net asset value.

     In selecting counterparties for OTC hedging and risk management
transactions, the Portfolio will adhere to the following minimum ratings: (i)
with respect to an OTC derivative instrument with a remaining nominal maturity
of six months or less, a Moody's Derivative Counterparty Rating of A3; (ii) with
respect to an OTC derivative instrument with a remaining maturity of more than
six months, a Moody's Derivative Counterparty Rating of AA3.  If the
counterparty does not have a Moody's counterparty rating, then either the
Moody's or S&P long-term securities rating of A3/A- (with respect to category
(i) above) or Aa3/AA- (with respect to category (ii) above) may be used as a
substitute.  In addition, all such counterparties must have a minimum short-term
rating of A-1 by Moody's and P-1 by S&P.  If a counterparty drops below the
minimum ratings, then the Portfolio will seek to unwind existing agreements with
such counterparty in a cost-effective manner and will be prohibited from
entering into new agreements with the counterparty so long as the counterparty's
rating is below the relevant minimum.

     The principal risks relating to the use of futures contracts and other
Additional Investment Management Techniques are:  (a) less than perfect
correlation between the prices of the instrument and the market value of the
securities in the Portfolio's holdings; (b) possible lack of a liquid secondary
market for closing out a position in such instruments; (c) losses resulting from
interest rate or other market movements not anticipated by the Adviser; and (d)
the obligation to

                                      -16-
<PAGE>

meet additional variation margin or other payment requirements, all of which
could result in the Portfolio being in a worse position than if such techniques
had not been used. See Appendix B "General Characteristics and Risks of
Additional Investment Management Techniques" for further information.

     The Portfolio may also purchase securities on a "when-issued" basis and may
purchase or sell securities on a "forward commitment," including "TBA" (to be
announced) basis.  When such transactions are negotiated, the price, which is
generally expressed in yield terms, is fixed at the time the commitment is made,
but delivery and payment for the securities take place at a later date outside
the normal course of settlement for securities of that type.  When-issued and
forward commitment transactions involve the risk that the price or yield
obtained in a transaction may be less favorable than the price or yield
available in the market when the securities delivery takes place.  When-issued
securities and forward commitments may be illiquid.  If the Portfolio disposes
of the right to acquire a when-issued security prior to its acquisition or
disposes of its right to deliver or receive against a forward commitment, it can
incur a gain or loss.  At the time the Portfolio enters into a transaction on a
when-issued or forward commitment basis, it will segregate with its custodian
cash or other liquid debt securities with a value not less than the value of the
when-issued or forward commitment securities.  The value of these assets will be
monitored daily to ensure that their marked to market value will at all times
equal or exceed the corresponding obligations of the Portfolio.  If deemed
advisable as a matter of investment strategy, the Portfolio may dispose of or
renegotiate a commitment after it has been entered into, and may sell securities
it has committed to purchase before those securities are delivered to the
Portfolio on the settlement date.  In these cases the Portfolio may realize a
taxable capital gain or loss.  When the Portfolio engages in when-issued, TBA or
forward commitment transactions, it relies on the other party to consummate the
trade.  Failure of such party to do so may result in the Portfolio's incurring a
loss or missing an opportunity to obtain a price considered to be advantageous.
The market value of the securities underlying a commitment to purchase
securities, and any subsequent fluctuations in their market value, is taken into
account when determining the market value of the Portfolio starting on the day
the Portfolio agrees to purchase the securities.  The Portfolio does not earn
interest on the securities it has committed to purchase until they are paid for
and delivered on the settlement date. Settlements in the ordinary course, which
typically occur monthly for mortgage-related securities, are not treated by the
Portfolio as when-issued or forward commitment transactions and accordingly are
not subject to the foregoing restrictions.

     Interest Rate Transactions.  The Portfolio may enter into interest rate
swaps and the purchase or sale of interest rate caps and floors.  The Portfolio
expects to enter into these transactions primarily to preserve a return or
spread on a particular investment or portion of its portfolio as a duration
management technique or to protect against any increase in the price of
securities that the Portfolio anticipates purchasing at a later date.  The
Portfolio will use these transactions as a hedge or for duration or risk
management.  The Portfolio will not sell interest rate caps or floors that it
does not own.  Interest rate swaps involve the exchange by the Portfolio

                                      -17-
<PAGE>

with another party of their respective commitments to pay or receive interest
e.g., an exchange of floating rate payments for fixed rate payments with respect
- ----
to a notional amount of principal. The purchase of an interest rate cap entitles
the purchaser, to the extent that a specified index exceeds a predetermined
interest rate, to receive payments of interest on a notional principal amount
from the party selling such interest rate cap. The purchase of an interest rate
floor entitles the purchaser, to the extent that a specified index falls below a
predetermined interest rate, to receive payments of interest on a notional
principal amount from the party selling such interest rate floor.

     The Portfolio may enter into interest rate swaps, caps and floors on either
an asset-based or liability-based basis, and will usually enter into interest
rate swaps on a net basis, i.e., the two payment streams are netted out, with
                           ----
the Portfolio receiving or paying, as the case may be, only the net amount of
the two payments on the payment dates.  The Portfolio will accrue the net amount
of the excess, if any, of the Portfolio's obligations over its entitlements with
respect to each interest rate swap on a daily basis and will segregate with a
custodian an amount of cash or liquid securities having an aggregate net asset
value at all times at least equal to the accrued excess.  If there is a default
by the other party to such a transaction, the Portfolio will have contractual
remedies pursuant to the agreements related to the transaction.

     Futures Contracts and Options on Futures Contracts.  The Portfolio may also
enter into contracts for the purchase or sale for future delivery ("futures
contracts") of debt securities, aggregates of debt securities or indices or
prices thereof, other financial indices and U.S. government debt securities or
options on the above.  Futures contracts will not, however, relate to Mortgage-
Backed Securities unless they are Commercial Mortgage-Backed Securities.  The
Portfolio will ordinarily engage in such transactions only for bona fide
hedging, risk management (including duration management) and other portfolio
management purposes.

     Calls on Securities, Indices and Futures Contracts.  The Portfolio may sell
or purchase call options ("calls") on U.S. Treasury securities, Mortgage-Backed
Securities, other debt securities, indices, and Eurodollar instruments that are
traded on U.S. and foreign securities exchanges and in the over-the-counter
markets, and futures contracts.  Calls will not relate to Mortgage-Backed
Securities unless they are Commercial Mortgage-Backed Securities.  A call gives
the purchaser of the option the right to buy, and obligates the seller to sell,
the underlying security, futures contract or index at the exercise price at any
time or at a specified time during the option period.  All such calls sold by
the Portfolio must be "covered" as long as the call is outstanding (i.e., the
                                                                    ----
Portfolio must own the securities or futures contract subject to the call or
other securities acceptable for applicable segregation requirements).  A call
sold by the Portfolio exposes the Portfolio during the term of the option to
possible loss of opportunity to realize appreciation in the market price of the
underlying security, index or futures contract and may require the Portfolio to
hold a security or futures contract which it might otherwise have sold.  The
purchase of a call gives the Portfolio the right to buy a security, futures
contract or index at a fixed price.  Calls on futures on U.S. Treasury
securities, Commercial Mortgage-Backed

                                      -18-
<PAGE>

Securities, other debt securities and Eurodollar instruments must also be
covered by deliverable securities or the futures contract or by liquid debt
securities segregated to satisfy the Portfolio's obligations pursuant to such
instruments.

     Puts on Securities, Indices and Futures Contracts.  The Portfolio may
purchase put options ("puts") that relate to U.S. Treasury securities,
Commercial Mortgage-Backed Securities, other debt securities and Eurodollar
instruments (whether or not it holds such securities in its portfolio), indices
or futures contracts.  The Portfolio may also sell puts on U.S. Treasury
securities, Commercial Mortgage-Backed Securities, other debt securities,
Eurodollar instruments, indices or futures contracts on such securities if the
Portfolio's contingent obligations on such puts are secured by segregated assets
consisting of cash or liquid debt securities having a value not less than the
exercise price.  No puts referred to in the preceding two sentences will relate
to Mortgage-Backed Securities unless they are Commercial Mortgage-Backed
Securities.  The Portfolio will not sell puts if, as a result, more than 50% of
the Portfolio's assets would be required to cover its potential obligations
under its hedging and other investment transactions.  In selling puts, there is
a risk that the Portfolio may be required to buy the underlying instrument at a
price higher than the current market price.

     Repurchase Agreements.  The Portfolio may invest temporarily in repurchase
agreements, which are agreements pursuant to which securities are acquired by
the Portfolio from a third party with the understanding that they will be
repurchased by the seller at a fixed price on an agreed date.  These agreements
may be made with respect to any of the portfolio securities in which the
Portfolio is authorized to invest.  Repurchase agreements may be characterized
as loans secured by the underlying securities and will be entered into in
accordance with the requirements of the SEC. The Portfolio will not enter into
any repurchase agreement with respect to securities other than U.S. Government
Securities (as defined in the Prospectus) and Commercial Mortgage-Backed
Securities.  The value of the collateral for such repurchase agreement marked-
to-market at the end of each business day will be at least equal to the amount
of the repurchase agreement.  The Portfolio will not enter into any repurchase
agreement the term of which exceeds 90 days.

     The repurchase price under the repurchase agreements generally equals the
price paid by the Portfolio plus interest negotiated on the basis of current
short-term rates (which may be more or less than the rate on securities
underlying the repurchase agreement).  The financial institutions with which the
Portfolio may enter into repurchase agreements will be banks and non-bank
dealers of U.S. Government Securities that are listed on the Federal Reserve
Bank of New York's list of reporting dealers, if such banks and non-bank dealers
are deemed creditworthy by the Adviser.  The Adviser will continue to monitor
creditworthiness of the seller under a repurchase agreement, and will require
the seller to maintain during the term of the agreement the value of the
securities subject to the agreement to equal at least the repurchase price
(including accrued interest).  In addition, the Adviser will require that the
value of this collateral, after transaction costs (including loss of interest)
reasonably expected to be incurred on a default, be

                                      -19-
<PAGE>

equal to or greater than the repurchase price (including accrued premium)
provided in the repurchase agreement. The accrued premium is the amount
specified in the repurchase agreement or the daily amortization of the
difference between the purchase price and the repurchase price specified in the
repurchase agreement. The Portfolio's Adviser will mark-to-market daily the
value of the securities. Securities subject to repurchase agreements will be
held by the Fund's custodian (or sub-custodian) in the Federal Reserve/Treasury
book-entry system or by another authorized securities depository. Repurchase
agreements are considered to be loans by the Portfolio under the 1940 Act.

     The use of repurchase agreements involves certain risks.  For example, if
the seller of securities under a repurchase agreement defaults on its obligation
to repurchase the underlying securities, as a result of its bankruptcy or
otherwise, the Portfolio will seek to dispose of such securities, which action
could involve costs or delays.  If the seller becomes insolvent and subject to
liquidation or reorganization under applicable bankruptcy or other laws, the
Portfolio's ability to dispose of the underlying securities may be restricted.
Finally, it is possible that the Portfolio may not be able to substantiate its
interest in the underlying securities.  To minimize this risk, the securities
underlying the repurchase agreement will be held by the custodian at all times
in an amount at least equal to the repurchase price, including accrued interest.
If the seller fails to repurchase the securities, the Portfolio may suffer a
loss to the extent proceeds from the sale of the underlying securities are less
than the repurchase price.

     Bank and Corporate Debt Securities.  The Portfolio may not invest in bank
or corporate debt securities except that it may invest in (i) debt securities of
REITs and REOCs as described herein and in the Prospectus and (ii) money market
instruments for temporary defensive purposes and in order to keep cash on hand
fully invested.  Investing in money market instruments for temporary defensive
purposes may prevent the Portfolio from achieving its investment objective.
Money market instruments include, but are not limited to notes, certificates of
deposit, bankers' acceptances, commercial paper and repurchase agreements.

     Floating Rate and Index Obligations.  The Portfolio may invest in debt
securities with interest payments or maturity values that are not fixed, but
float in conjunction with an underlying index or price.  These securities may be
backed by U.S. Government or corporate issuers, or by collateral such as
commercial (but not residential) mortgages.  In certain cases, a change in the
underlying index or price may have a leveraging effect on the periodic coupon
payments, creating larger possible swings in the prices of such securities than
would be expected when taking into account their maturities alone.  The indices
and prices upon which such securities can be based include interest rates,
currency rates and commodities prices.  However, the Portfolio will not invest
in any instrument whose value is computed based on a multiple of the change in
price or value of an asset or an index of or relating to assets in which the
Portfolio could not invest.

                                      -20-
<PAGE>

     Floating rate securities pay interest according to a coupon which is reset
periodically.  This reset mechanism may be formula based, or reflect the passing
through of floating interest payments on an underlying collateral pool. The
coupon is usually reset daily, weekly, monthly, quarterly or semi-annually, but
other schedules are possible. Floating rate obligations generally exhibit a low
price volatility for a given stated maturity or average life because their
coupons adjust with changes in interest rates. If their underlying index is not
an interest rate, or the reset mechanism lags the movement of rates in the
current market, greater price volatility may be experienced.

     Index securities pay a fixed rate of interest, but have a maturity value
that varies by formula, so that when the obligation matures a gain or loss is
realized.  The risk of index obligations depends on the volatility of the
underlying index, the coupon payment and the maturity of the obligation.

     REITs.  The Portfolio may invest in the corporate debt of real estate
investment trusts ("REITs"), which are pooled investment vehicles which invest
primarily in income producing real estate ("Equity REITs"). Equity REITs invest
the majority of their assets directly in real property and derive income
primarily from the collection of rents.  Equity REITs can also realize capital
gains by selling properties that have appreciated in value.  The Portfolio may
not invest in REITs which invest the majority of their assets in real estate
mortgages and derive income from the collection of interest payments.  REITs are
not taxed on income distributed to shareholders provided they comply with
certain requirements of the Internal Revenue Code of 1986, as amended (the
"Code").  The Portfolio will indirectly bear its proportionate share of any
expenses paid by Equity REITs in which it invests.

     Investing in Equity REITs involves certain unique risks in addition to
those risks associated with investing in the real estate industry in general.
Equity REITs may be affected by changes in the value of the underlying property
they own.  Equity REITs are dependent on management skills, are not diversified,
and are subject to the risks of financing projects.  Equity REITs are subject to
heavy cash flow dependency and the possibilities of failing to qualify for the
exemption from tax for distributed income under the Code and failing to maintain
their exemptions from the 1940 Act.  Equity REITs whose underlying assets
include long-term health care properties, such as nursing, retirement and
assisted living homes may be impacted by federal regulations concerning the
health care industry.

     Equity REITs may have limited financial resources, may trade less
frequently and in a limited volume and may be subject to more abrupt or erratic
price movements than larger company securities.  Historically, Equity REIT's
have been more volatile in price than larger capitalization stocks.

     Restricted and Illiquid Securities.  Illiquid securities are subject to
legal or contractual restrictions on disposition or lack an established
secondary trading market.  The sale of restricted

                                      -21-
<PAGE>

and illiquid securities often requires more time and results in higher brokerage
charges or dealer discounts and other selling expenses than does the sale of
securities eligible for trading on national securities exchanges or in the over-
the-counter markets. Restricted securities may sell at a price lower than
similar securities that are not subject to restrictions on resale. The Portfolio
may purchase certain restricted securities ("Rule 144A securities") eligible for
sale to qualified institutional buyers as contemplated by Rule 144A under the
Securities Act of 1933. Rule 144A provides an exemption from the registration
requirements of the Securities Act of 1933 for the resale of certain restricted
securities to qualified institutional buyers. One effect of Rule 144A is that
certain restricted securities may now be liquid, though no assurance can be
given that a liquid market for Rule 144A securities will develop or be
maintained. The Portfolio's holdings of Rule 144A securities which are liquid
securities will not be subject to its limitation on investment in illiquid
securities. The Fund's Board of Trustees has adopted policies and procedures for
the purpose of determining whether securities that are eligible for resale under
Rule 144A are liquid or illiquid. The Board of Trustees will periodically review
the Portfolio's purchases and sales of Rule 144A securities.

Other Investments

     U.S. Government Securities

     U.S. Government Securities (as defined in the Prospectus) include:

            1.      U.S. Treasury bills (maturities of one year or less), U.S.
        Treasury notes (maturities of one to ten years) and U.S. Treasury bonds
        (generally maturities of greater than ten years), all of which are
        direct obligations of the U.S. Government and, as such, are backed by
        the "full faith and credit" of the United States.

            2.      Securities issued by agencies and instrumentalities of the
        U.S. Government which are backed by the full faith and credit of the
        United States. Among the agencies and instrumentalities issuing such
        obligations are the Department of Housing and Urban Development, the
        Export-Import Bank, the Farmers Home Administration ("FHA"), the General
        Services Administration, the Maritime Administration and the Small
        Business Administration. The maturities of such obligations range from
        three months to 30 years.

            3.      Securities issued by agencies and instrumentalities which
        are not backed by the full faith and credit of the United States, but
        whose issuing agency or instrumentalities may borrow, to meet its
        obligations, from the U.S. Treasury. Among the agencies and
        instrumentalities issuing such obligations are the Tennessee Valley
        Authority and the U.S. Postal Service.

            4.      Securities issued by agencies and instrumentalities which
        are not backed by the full faith and credit of the United States, but
        which are backed by the credit of the issuing agency or instrumentality.
        Among the agencies and instrumentalities issuing such obligations is the
        Federal Farm Credit System.

     Neither the value nor the yield of the Portfolio's shares or of the U.S.
Government Securities which may be invested in by the Portfolio are guaranteed
by the U.S. Government.  Such values and yield will fluctuate with changes in
prevailing interest rates and other factors.  Generally, as prevailing interest
rates rise, the value of any U.S. Government Securities held by the Portfolio
will fall.  Such securities with longer maturities generally tend to produce
higher yields and are subject to greater market fluctuation, as a result of
changes in interest rates, than debt securities with shorter maturities.

                            INVESTMENT RESTRICTIONS

     With the exception of the investment limitations enumerated in this
section, the investment policies and limitations enumerated in this Statement of
Additional Information and in the Prospectus may be changed by the Fund's Board
of Trustees.  The investment limitations enumerated in this section, however,
may be changed only by a vote of the holders of a majority of the Portfolio's
outstanding shares (as defined below under "Miscellaneous").

     The Portfolio may not:

          (1)     invest 25% or more of the value of its total assets in any one
                  industry (Mortgage-Backed Securities and other securities
                  issued or guaranteed by the U.S. government or any agency or
                  instrumentality thereof are not treated as industries);
                  provided, however, that the Portfolio will, except for
                  temporary defensive purposes, invest at least 65% of the value
                  of its total assets in Commercial Mortgage-Backed Securities;

          (2)     issue senior securities (including borrowing money, including
                  on margin if margin securities are owned) in excess of 33 1/3%
                  of its total assets (including the amount of senior securities
                  issued but excluding any liabilities and indebtedness not
                  constituting senior securities) except that the Portfolio may
                  borrow up to an additional 5% of its total assets for
                  temporary purposes; or pledge its assets other than to secure
                  such issuances or in connection with hedging transactions,
                  short sales, when-issued and forward commitment transactions
                  and similar investment strategies. The Portfolio's obligations
                  under interest rate swaps are not treated as senior
                  securities;

                                      -23-

          (3)     make loans of money or property to any person, except through
                  loans of portfolio securities, the purchase of fixed income
                  securities consistent with the Portfolio's investment
                  objective and policies or the acquisition of securities
                  subject to repurchase agreements;

          (4)     underwrite the securities of other issuers, except to the
                  extent that in connection with the disposition of portfolio
                  securities or the sale of its own shares the Portfolio may be
                  deemed to be an underwriter;

          (5)     invest for the purpose of exercising control over management
                  of any company other than issuers of collateralized mortgage
                  obligations;

          (6)     purchase real estate or interests therein other than
                  Commercial and Residential Mortgage-Backed Securities and
                  similar instruments;

          (7)     purchase or sell commodities or commodity contracts for any
                  purposes except as, and to the extent, permitted by applicable
                  law without the Portfolio becoming subject to registration
                  with the Commodity Futures Trading Commission as a commodity
                  pool;

          (8)     make any short sale of securities except in conformity with
                  applicable laws, rules and regulations and unless, giving
                  effect to such sale, the market value of all securities sold
                  short does not exceed 25% of the value of the Portfolio's
                  total assets and the Portfolio's aggregate short sales of a
                  particular class of securities does not exceed 25% of the then
                  outstanding securities of that class;

          (9)     invest in non-U.S. dollar denominated securities or other
                  instruments; or

          (10)    hold Additional Investment Management Techniques to the extent
                  that the aggregate notional value thereof exceeds 50% of the
                  Portfolio's total assets (determined after excluding all such
                  Additional Investment Management Techniques).

     Notwithstanding restriction 2 above, the Portfolio has no present intention
to issue senior securities.

     Shareholder and Trustee Liability.  Under Massachusetts law, shareholders
of a business trust may, under certain circumstances, be held personally liable
as partners for the obligations of the trust.  However, the Fund's Declaration
of Trust provides that shareholders shall not be subject to any personal
liability in connection with the assets of the Fund for the acts or obligations
of the Fund, and that every note, bond, contract, order or other undertaking
made by the Fund shall contain a provision to the effect that the shareholders
are not personally liable thereunder.  The Declaration of Trust provides for
indemnification out of the trust property of any shareholder held personally
liable solely by reason of his being or having been a shareholder and not
because of his acts or omissions or some other reason.  The Declaration of Trust
also

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

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.

provides that the Fund shall, upon request, assume the defense of any claim made
against any shareholder for any act or obligation of the Fund, and shall satisfy
any judgment thereon.

    The Declaration of Trust further provides that all persons having any claim
against the trustees or Fund shall look solely to the trust property for
payment; that no trustee of the Fund shall be personally liable for or on
account of any contract, debt, tort, claim, damage, judgment or decree arising
out of or connected with the administration or preservation of the trust
property or the conduct of any business of the Fund; and that no trustee shall
be personally liable to any person for any action or failure to act except by
reason of his own bad faith, willful misfeasance, gross negligence or reckless
disregard of his duties as a trustee.  With the exception stated, the
Declaration of Trust provides that a trustee is entitled to be indemnified
against all liabilities and expenses reasonably incurred by him in connection
with the defense or disposition of any proceeding in which he may be involved or
with which he may be threatened by reason of his being or having been a trustee,
and that the Fund will indemnify officers, representatives and employees of the
Fund to the same extent that trustees are entitled to indemnification.

                    DISTRIBUTION AND SERVICING ARRANGEMENTS

     Advisory Agreement.  The advisory services provided by BlackRock, an
indirect majority-owned subsidiary of PNC Bank Corp., are described in the
Prospectus.  For its services as adviser, BlackRock is entitled to an annual fee
equal to .25% of the Portfolio's average daily net assets.  BlackRock may from
time to time voluntarily waive its advisory fees with respect to the Portfolio
and may voluntarily reimburse the Portfolio for expenses.

     BlackRock renders advisory services to the Portfolio pursuant to an
Investment Advisory Agreement (the "Advisory Contract").  Under the Advisory
Contract, BlackRock is not liable for any error of judgment or mistake of law or
for any loss suffered by the Fund or the Portfolio in connection with the
performance of the Advisory Contract, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of BlackRock in the
performance of its duties or from reckless disregard of its duties and
obligations thereunder.  The Advisory Contract is terminable as to the Portfolio
by vote of the Board of Trustees or by the holders of a majority of the
outstanding voting securities of the Portfolio, at any time without penalty, on
60 days' written notice to BlackRock.  BlackRock may also terminate its advisory
relationship with respect to the Portfolio, on 60 days' written notice to the
Fund.  The Advisory Contract terminates automatically in the event of its
assignment.

     Administration Agreement.  The Fund has entered into an Administration
Agreement with BAI, whose principal business address is 345 Park Avenue, New
York, New York 10154, and PFPC, whose principal business address is 400 Bellevue
Parkway, Wilmington, DE  19809 (the "Administration Agreement").  PFPC has

connection with a Portfolio's shares; provide oversight and related support
services that are intended to ensure the delivery of quality service to the
holders of the Portfolio's shares; and provide certain other services required

the negotiation of service contracts and arrangements between the Fund and its
service providers; acting as liaison between the trustees of the Fund and the
Fund's service providers; and providing ongoing business management and support
services in connection with the Fund's operations.

                                      -32-
<PAGE>

     Under the Administration Agreement, the Fund pays to BAI and PFPC on behalf
of the Portfolio a fee, computed daily and payable monthly, at an aggregate
annual rate of .23% of the first $500 million of the Portfolio's average daily
net assets, .21% of the next $500 million of the Portfolio's average daily net
assets and .19% of the average daily net assets of the Portfolio in excess of $1
billion.  From time to time, BAI and PFPC may waive some or all of their
administration fees from the Portfolio.

     The Administration Agreement provides that BAI and PFPC will not be liable
for any error of judgment or mistake of law or for any loss suffered by the Fund
or the Portfolio in connection with the performance of the Administration
Agreement, except a loss resulting from willful misfeasance, bad faith or gross
negligence in the performance of their respective duties or from reckless
disregard of their respective duties and obligations thereunder.  In addition,
the Fund will indemnify each of BAI and PFPC and their affiliates against any
loss arising in connection with their provision of services under the
Administration Agreement, except that neither BAI nor PFPC nor their affiliates
shall be indemnified against any loss arising out of willful misfeasance, bad
faith, gross negligence or reckless disregard of their duties under the
Administration Agreement.

     Pursuant to the terms of the Administration Agreement, BAI has delegated
certain of its duties thereunder to BDI.

     Custodian and Transfer Agency Agreements. PTC, an affiliate of PNC Bank,
whose principal business address is 1600 Market Street, Philadelphia,
Pennsylvania 19103, is custodian of the Fund's assets pursuant to a custodian
agreement (the "Custodian Agreement").  Under the Custodian Agreement, PTC or a
sub-custodian (i) maintains a separate account or accounts in the name of the
Portfolio, (ii) holds and transfers portfolio securities on account of the
Portfolio, (iii) accepts receipts and makes disbursements of money on behalf of
the Portfolio, (iv) collects and receives all income and other payments and
distributions on account of the Portfolio's securities and (v) makes periodic
reports to the Board of Trustees concerning the Portfolio's operations.  PTC is
authorized to select one or more banks or trust companies to serve as sub-
custodian on behalf of the Fund, provided that, with respect to sub-custodians
other than sub-custodians for foreign securities, PTC remains responsible for
the performance of all its duties under the Custodian Agreement and holds the
Fund harmless from the acts and omissions of any sub-custodian.  Citibank, N.A.
serve as the international sub-custodians for various portfolios of the Fund.

     For its services to the Fund under the Custodian Agreement, PTC receives a
fee which is calculated based upon the Portfolio's average gross assets, with a
minimum monthly fee of $1,000 per investment portfolio.  PTC is also entitled to
out-of pocket expenses and certain transaction charges.

                                      -33-
<PAGE>

     PFPC, an affiliate of PNC Bank, serves as the transfer and dividend
disbursing agent for the Fund pursuant to a Transfer Agency Agreement (the
"Transfer Agency Agreement"), under which PFPC (i) issues and redeems shares in
the Portfolio, (ii) addresses and mails all communications by the Portfolio to
record owners of its shares, including reports to shareholders, dividend and
distribution notices and proxy materials for its meetings of shareholders, (iii)
maintains shareholder accounts and, if requested, sub-accounts and (iv) makes
periodic reports to the Board of Trustees concerning the operations of the
Portfolio.  PFPC may, on 30 days' notice to the Fund, assign its duties as
transfer and dividend disbursing agent to any other affiliate of PNC Bank Corp.
For its services with respect to the Fund's Institutional Shares under the
Transfer Agency Agreement, PFPC is entitled to receive fees at the annual rate
of .03% of the average net asset value of outstanding Institutional Shares in
the Portfolio, plus per account fees and disbursements.

     Distributor and Distribution Plan.  The Fund has entered into a
distribution agreement with the Distributor under which the Distributor, as
agent, offers shares of the Portfolio on a continuous basis.  The Distributor
has agreed to use appropriate efforts to effect sales of the shares, but it is
not obligated to sell any particular amount of shares.  The Distributor is a
registered broker/dealer with principal offices at Four Falls Corporate Center,
6th Floor, West Conshohocken, PA  19428-2961. The Distributor is a wholly-owned
subsidiary of Provident Distributors, Inc. ("PDI").  A majority of the
outstanding stock of PDI is owned by its officers.

     The Fund has adopted an Amended and Restated Distribution and Service Plan
(the "Plan") pursuant to Rule 12b-1 under the 1940 Act on behalf of its
Institutional Shares.  The Plan was approved by a majority of (i) the trustees
of the Fund and (ii) the trustees of the Fund who are not interested persons of
the Fund and who have no direct or indirect financial interest in the operation
of the Plan or in any agreement related to the Plan (the "Rule 12b-1 Trustees").

     The Fund is not required or permitted under the Plan to make distribution
payments with respect to its Institutional Shares.  However, the Plan permits
BDI, BAI, PFPC and other companies that receive fees from the Fund to make
payments relating to distribution and sales support activities out of their past
profits or other sources available to them.  The Distributor, BAI and their
affiliates may pay financial institutions, broker/dealers and/or their
salespersons certain compensation for the sale and distribution of shares of the
Fund or for services to the Fund.  These payments ("Additional Payments") may
take the form of "due diligence" payments for a dealer's examination of the
Portfolio and payments for providing extra employee training and information
relating to the Portfolio; "listing" fees for the placement of the Portfolio on
a dealer's list of mutual funds available for purchase by its customers;
"finders" or "referral" fees for directing investors to the Fund; "marketing
support" fees for providing assistance in promoting the sale of the Funds'
shares; and payments for the sale of shares and/or the maintenance of share
balances.  In addition, the Distributor, BAI and their affiliates may make
Additional Payments for subaccounting, administrative and/or shareholder
processing services.  The Additional Payments made by the Distributor, BAI and
their affiliates may be a fixed dollar

                                      -34-
<PAGE>

amount, may be based on the number of customer accounts maintained by a
financial institution or broker/dealer, or may be based on a percentage of the
value of shares sold to, or held by, customers of the financial institutions or
dealers involved, and may be different for different institutions and dealers.
Furthermore, the Distributor, BAI and their affiliates may contribute to various
non-cash and cash incentive arrangements to promote the sale of shares, and may
sponsor various contests and promotions subject to applicable NASD regulations
in which participants may receive prizes such as travel awards, merchandise and
cash.  The Distributor, BAI and their affiliates may also pay for the travel
expenses, meals, lodging and entertainment of broker/dealers, financial
institutions and their salespersons in connection with educational and sales
promotional programs subject to applicable NASD regulations.

     The Plan will continue from year to year, provided that each such
continuance is approved at least annually by a vote of the Board of Trustees,
including a majority vote of the Rule 12b-1 Trustees, cast in person at a
meeting called for the purpose of voting on such continuance.  The Plan may be
terminated with respect to the Portfolio at any time, without penalty, by the
vote of a majority of the Rule 12b-1 Trustees or by a vote of the holders of a
majority of the outstanding shares of the Portfolio.  The Plan may not be
amended materially without the approval of the Board of Trustees, including a
majority of the Rule 12b-1 Trustees, cast in person at a meeting called for that
purpose.  Any modification to the Plan which would materially increase the costs
borne by the Portfolio for distribution purposes pursuant to the Plan must also
be submitted to the stockholders of the Portfolio for approval.   In addition,
while the Plan remains in effect, the selection and nomination of the Fund's
trustees who are not "interested persons" of the Fund shall be committed to the
discretion of the Fund's non-interested trustees.

                             PORTFOLIO TRANSACTIONS

     The Adviser is responsible for decisions to buy and sell securities for the
Portfolio, the selection of brokers and dealers to effect the transactions and
the negotiation of prices and any brokerage commissions.  The securities in
which the Portfolio invests are traded principally in the over-the-counter
market.  In the over-the-counter market, securities are generally traded on a
"net" basis with dealers acting as principal for their own accounts without a
stated commission, although the price of the security usually includes a mark-up
to the dealer.  Securities purchased in underwritten offerings generally
include, in the price, a fixed amount of compensation for the manager(s),
underwriter(s) and dealer(s).  The Portfolio may also purchase certain money
market instruments directly from an issuer, in which case no commissions or
discounts are paid.  Purchases and sales of debt securities on a stock exchange
are effected through brokers who charge a commission for their services.

     The Adviser's primary considerations in selecting the manner of executing
securities transactions for the Portfolio will be prompt execution of orders,
the size and breadth of the market for the security, the reliability, integrity
and financial condition and execution capability of the firm, the size of and
difficulty in executing the order, and the best net price.  There are

                                      -35-
<PAGE>

many instances when, in the judgment of the Adviser, more than one firm can
offer comparable execution services.  In selecting among such firms,
consideration is given to those firms which supply research and other services
in addition to execution services.  However, it is not the policy of the
Adviser, absent special circumstances, to pay higher commissions to a firm
because it has supplied such services.

     The Adviser is able to fulfill its obligations to furnish a continuous
investment program to the Portfolio without receiving such information from
brokers; however, it considers access to such information to be an important
element of financial management.  Although such information is considered
useful, its value is not determinable, as it must be reviewed and assimilated by
the Adviser, and does not reduce the Adviser's normal research activities in
rendering investment advice under the Advisory Contract.  It is possible that
the Adviser's expenses could be materially increased if it attempted to purchase
this type of information or generate it through its own staff.

     One or more of the other accounts which the Adviser manages may own from
time to time the same investments as the Portfolio.  Investment decisions for
the Portfolio are made independently from those of such other accounts; however,
from time to time, the same investment decision may be made for more than one
company or account.  When two or more companies or accounts seek to purchase or
sell the same securities, the securities actually purchased or sold will be
allocated among the companies and accounts on a good faith equitable basis by
the Adviser in its discretion in accordance with the accounts' various
investment objectives.  In some cases, this system may adversely affect the
price or size of the position obtainable for the Portfolio.  In other cases,
however, the ability of the Portfolio to participate in volume transactions may
produce better execution for the Portfolio.

     Although the Advisory Agreement contains no restrictions on portfolio
turnover, it is not the policy of the Portfolio to engage in transactions with
the objective of seeking profits from short-term trading.  It is expected that
the annual portfolio turnover rate of the Portfolio will not exceed 250%,
excluding securities having a maturity of one year or less.  Because it is
difficult to predict accurately portfolio turnover rate, actual turnover may be
higher or lower.  Higher portfolio turnover results in increased Portfolio
expenses, including brokerage commissions, dealer mark-ups and other transaction
costs on the sale of securities and on reinvestment in other securities.  The
Adviser will monitor the tax status of the Portfolio under the Internal Revenue
Code during periods in which the annual turnover rate of the Portfolio exceeds
100%.  The portfolio turnover rate of the Portfolio is calculated by dividing
the lesser of the Portfolio's annual sales or purchases of portfolio securities
(exclusive of purchases or sales of securities whose maturities at the time of
acquisition were one year or less) by the monthly average value of the
securities held by the Portfolio during the year.

     The Portfolio will not purchase securities during the existence of any
underwriting or selling group relating to such securities of which BAI, BIMC,
BlackRock, PNC Bank, BIL,

                                      -36-
<PAGE>

PFPC, the Distributor or any affiliated person (as defined in the 1940 Act)
thereof is a member except pursuant to procedures adopted by the Board of
Trustees in accordance with Rule 10f-3 under the 1940 Act.  In no instance will
portfolio securities be purchased from or sold to BAI, BIMC, BlackRock, PNC
Bank, BIL, PFPC, the Distributor or any affiliated person of the foregoing
entities except as permitted by SEC exemptive order or by applicable law.


                      PURCHASE AND REDEMPTION INFORMATION

     Institutional Shares of the Portfolio are sold at the net asset value per
share next determined after a purchase order is received.

     The Fund has elected to be governed by Rule 18f-1 under the 1940 Act so
that the Portfolio is obligated to redeem its shares solely in cash up to the
lesser of $250,000 or 1% of its net asset value during any 90-day period for any
one shareholder of the Portfolio.

     Under the 1940 Act, the Portfolio may suspend the right to redemption or
postpone the date of payment upon redemption for any period during which the New
York Stock Exchange (the "NYSE") is closed (other than customary weekend and
holiday closings), or during which trading on the NYSE 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.  (The Portfolio
may also suspend or postpone the recordation of the transfer of its shares upon
the occurrence of any of the foregoing conditions.)

     In addition to the situations described in the Prospectus, the Fund may
redeem shares involuntarily to reimburse the Portfolio for any loss sustained by
reason of the failure of a shareholder to make full payment for shares purchased
by the shareholder or to collect any charge relating to a transaction effected
for the benefit of a shareholder as provided in the Prospectus from time to
time.

                       VALUATION OF PORTFOLIO SECURITIES

     In determining the approximate market value of portfolio investments, the
Fund may employ outside organizations, which may use, without limitation, a
matrix or formula method that takes into consideration market indexes, matrices,
yield curves and other specific adjustments.  This may result in the securities
being valued at a price different from the price that would have been determined
had the matrix or formula method not been used.  All cash, receivables and
current payables are carried on the Fund's books at their face value.  Other
assets, if any, are valued at fair value as determined in good faith under the
supervision of the Board of Trustees.

                            PERFORMANCE INFORMATION

     From time to time, total return and yield data for Shares of the Portfolio
may be quoted in advertisements or in communications to Institutions.  Total
return will be calculated on an average annual total return basis for various
periods.  Average annual total return reflects the average annual percentage
change in value of an investment in Shares of the Portfolio over the measuring
period.  Total return may also be calculated on an aggregate total return basis.
Aggregate total return reflects the total percentage change in value over the
measuring period.  Both methods of calculating total return assume that
dividends and capital gain distributions made by the Portfolio during the period
relating to Shares are reinvested in Shares.

     The yield of Shares of the Portfolio is computed based on the net income of
the Portfolio allocated to such Shares during a 30-day (or one month) period,
which period will be identified in connection with the particular yield
quotation.  More specifically, the yield of Shares of the Portfolio is computed
by dividing the Portfolio's net income per share allocated to such Shares during
a 30-day (or one month) period by the net asset value per share on the last day
of the period and annualizing the result on a semi-annual basis.

     Performance data of Shares of the Portfolio may be compared to those of
other mutual funds with similar investment objectives and to other relevant
indexes or to ratings or rankings prepared by independent services or other
financial or industry publications that monitor the performance of mutual funds.
In addition, certain indexes may be used to illustrate historic performance of
select asset classes.  For example, the total return and/or yield of Shares of
the Portfolio may be compared to data prepared by Lipper Analytical Services,
Inc., CDA Investment Technologies, Inc. and Weisenberger Investment Company
Service, and with the performance of the Salomon Broad Investment Grade Index,
the T-Bill Index and the "stocks, bonds and inflation index" published annually
by Ibbotson Associates.  Performance information may also include evaluations of
the Portfolio and their Shares published by nationally recognized ranking
services and information as reported by financial publications such as Business
Week, Fortune, Institutional Investor, Money Magazine, Forbes, Barron's, The
Wall Street Journal and The New York Times, or in publications of a local or
regional nature.

     In addition to providing performance information that demonstrates the
actual yield or returns of Shares of the Portfolio over a particular period of
time, the Portfolio may provide certain other information demonstrating
hypothetical investment returns.  Such information may include, but is not
limited to, illustrating the compounding effects of a dividend in a dividend
reinvestment plan.

     Performance quotations of Shares of the Portfolio represent past
performance and should not be considered as representative of future results.
The investment return and principal value of an investment in Shares of the
Portfolio will fluctuate so that a shareholder's Shares, when redeemed, may be
worth more or less than their original cost.  Since performance will fluctuate,

                                      -38-
<PAGE>

performance data for Shares of the Portfolio cannot necessarily be used to
compare an investment in such 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 is generally a function of the kind and quality of the instruments
held in the portfolio, portfolio maturity, operating expenses and market
conditions.  Any fees charged by brokers or other institutions directly to their
customer accounts in connection with investments in Shares will not be included
in the Portfolio's calculations of yield and total return.

     Total Return.  For purposes of quoting and comparing the performance of
shares of the Portfolio to the performance of other mutual funds and to stock or
other relevant indexes in advertisements, sales literature, communications to
shareholders and other materials, performance may be stated in terms of total
return.  Under the rules of the SEC, funds advertising performance must include
total return quotes calculated according to the following formula:


                              [( ERV to the power of 1 divided by n)   ]
                      T =     [( ----------------------------------)- 1]
                              [                 P                      ]
          Where:      T =     average annual total return.

                    ERV =     ending redeemable value at the end of the period
                              covered by the computation of a hypothetical
                              $1,000 payment made at the beginning of the
                              period.

                      P =     hypothetical initial payment of $1,000.

                      n =     period covered by the computation, expressed in
                              terms of years.

     Total return, or "T" in the formula above, is computed by finding the
average annual compounded rates of return over the specified periods that would
equate the initial amount invested to the ending redeemable value.

     The Portfolio may also from time to time include in advertisements, sales
literature, communications to shareholders and other materials a total return
figure that is not calculated according to the formula set forth above in order
to compare more accurately the performance of the Portfolio's shares with other
performance measures.  For example, in comparing the total return of the
Portfolio's shares with data published by Lipper Analytical Services, Inc., CDA
Investment Technologies, Inc. or Weisenberger Investment Company Service, or
with the performance of the Salomon Broad Investment Grade Index, as
appropriate, the Portfolio may calculate the aggregate total return for its
shares for the period of time specified in the advertisement or communication by
assuming the investment of $10,000 in the Portfolio's shares and assuming the
reinvestment of each dividend or other distribution at net asset value on the

                                      -39-
<PAGE>

reinvestment date.  Percentage increases are determined by subtracting the
initial value of the investment from the ending value and by dividing the
remainder by the beginning value.

     In addition to average annual total returns, the Portfolio may quote
unaveraged or cumulative total returns reflecting the simple change in value of
an investment over a stated period.  Average annual and cumulative total returns
may be quoted as a percentage or as a dollar amount, and may be calculated for a
single investment, a series of investments, or a series of redemptions, over any
time period.  Total returns may be broken down into their components of income
and capital (including capital gains and changes in share price) in order to
illustrate the relationship of these factors and their contributions to total
return.  Total returns may be quoted on a before-tax or after-tax basis.  Total
returns, yields, and other performance information may be quoted numerically or
in a table, graph or similar illustration.

     Yield.  The Portfolio may advertise its yield on its Institutional Shares.
Under the rules of the SEC, the Portfolio must calculate yield using the
following formula:



                    ( a-b   )
          YIELD = 2[( --- +1) to the sixth power - 1]
                    ( cd    )

          Where:  a =   dividends and interest earned during  the period.

                  b =   expenses accrued for the period (net of reimbursements).

                  c =   the average daily number of shares outstanding during
                        the period that were entitled to receive dividends.

                  d =   the maximum offering price per share on the last day of
                        the period.

     For the purpose of determining net investment income earned during the
period (variable "a" in the formula), dividend income on equity securities held
by the Portfolio is recognized by accruing 1/360th of the stated dividend rate
of the security each day that the security is in the Portfolio.  Except as noted
below, interest earned on any debt obligations held by the Portfolio is
calculated by computing the yield to maturity of each obligation held by the
Portfolio based on the market value of the obligation (including actual accrued
interest) at the close of business on the last business day of each month, or,
with respect to obligations purchased during the month, the purchase price (plus
actual accrued interest) and dividing the result by 360 and multiplying the
quotient by the market value of the obligation (including actual accrued
interest) in order to determine the interest income on the obligation for each
day of the subsequent month that the obligation is held by the Portfolio.  For
purposes of this calculation, it is assumed that each

                                      -40-
<PAGE>

month contains 30 days.  The maturity of an obligation with a call provision is
the next call date on which the obligation reasonably may be expected to be
called or, if none, the maturity date.

     With respect to debt obligations purchased at a discount or premium, the
formula generally calls for amortization of the discount or premium.

     With respect to mortgage or other receivables-backed obligations which are
expected to be subject to monthly payments of principal and interest ("pay
downs"), (a) gain or loss attributable to actual monthly pay downs are accounted
for as an increase or decrease to interest income during the period; and (b) the
Portfolio may elect either (i) to amortize the discount and premium on the
remaining security, based on the cost of the security, to the weighted-average
maturity date, if such information is available, or to the remaining term of the
security, if any, if the weighted-average maturity date is not available, or
(ii) not to amortize discount or premium on the remaining security.  The
amortization schedule will be adjusted monthly to reflect changes in the market
values of debt obligations.

     Undeclared earned income will be subtracted from the maximum offering price
per share (variable "d" in the formula).  Undeclared earned income is the net
investment income which, at the end of the base period, has not been declared as
a dividend, but is reasonably expected to be and is declared and paid as a
dividend shortly thereafter.

     Other Information Regarding Investment Returns.  In addition to providing
performance information that demonstrates the total return or yield of
Institutional Shares of the Portfolio over a specified period of time, the Fund
may provide certain other information demonstrating hypothetical investment
returns.  Such information may include, but is not limited to, illustrating the
compounding effects of a dividend in a dividend reinvestment plan.

     Miscellaneous.  Performance information for the Portfolio assumes the
reinvestment of dividends and distributions.  Performance information may
reflect fee waivers that subsidize and reduce the total operating expenses of
the Portfolio.  In these cases, the Portfolio's return would be lower if there
were not such waivers.

     Yield on shares of the Portfolio will fluctuate daily and does not provide
a basis for determining future yield.  Because yield will fluctuate, it cannot
be compared with yields on savings account or other investment alternatives that
provide an agreed to or guaranteed fixed yield for a stated period of time.  In
comparing the yield of one fund to another, consideration should be given to
each fund's investment policies, including the types of investments made,
lengths of maturities of the portfolio securities, and whether there are any
special account charges which may reduce the effective yield.  The fees which
may be imposed by authorized dealers and other institutions on their customers
are not reflected in the calculations of total returns or yields for the
Portfolio.

                                      -41-
<PAGE>

     As stated above, the Fund may also from time to time include discussions or
illustrations of the effects of compounding in advertisements.  "Compounding"
refers to the fact that, if dividends or other distributions on an investment in
the Portfolio are reinvested by being paid in additional Portfolio shares, any
future income or capital appreciation of the Portfolio would increase the value,
not only of the original investment in the Portfolio, but also of the additional
Portfolio shares received through reinvestment.  The Fund may also include
discussions or illustrations of the potential investment goals of a prospective
investor, investment management techniques, policies or investment suitability
of the Portfolio, economic conditions, the effects of inflation and historical
performance of various asset classes, including but not limited to, stocks,
bonds and Treasury bills.  From time to time advertisements or communications to
shareholders may summarize the substance of information contained in shareholder
reports (including the investment composition of the Portfolio), as well as the
views of BlackRock as to current market, economy, trade and interest rate
trends, legislative, regulatory and monetary developments, investment strategies
and related matters believed to be of relevance to the Portfolio.  The Fund may
also include in advertisements charts, graphs or drawings which illustrate the
potential risks and rewards of investment in various investment vehicles,
including but not limited to, stocks, bonds, treasury bills and shares of the
Portfolio.  In addition, advertisements or shareholder communications may
include a discussion of certain attributes or benefits to be derived by an
investment in the Portfolio.  Such advertisements or communications may include
symbols, headlines or other material which highlight or summarize the
information discussed in more detail therein.


                                     TAXES

     The following is only a summary of certain additional tax considerations
generally affecting the Portfolio and its shareholders.  No attempt is made to
present a detailed explanation of the tax treatment of the Portfolio or its
shareholders, and the discussion here and in the Prospectuses is not intended as
a substitute for careful tax planning.  Investors are urged to consult their tax
advisers with specific reference to their own tax situation.

     The Portfolio will elect to be taxed as a regulated investment company
under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code").  As a regulated investment company, the Portfolio generally is exempt
from federal income tax on its net investment income (i.e., its investment
company taxable income as that term is defined in the Code without regard to the
deduction for dividends paid) and net capital gain (i.e., the excess of net
long-term capital gain over net short-term capital loss) that it distributes to
shareholders, provided that it distributes an amount equal to at least 90% of
its net investment income (the "Distribution Requirement") and satisfies certain
other requirements of the Code that are described below.  Distributions of net
investment income made during the taxable year or, under specified
circumstances, within twelve months after the close of the taxable year will
satisfy the Distribution Requirement.

                                      -42-
<PAGE>

     In addition to satisfaction of the Distribution Requirement, the Portfolio
must derive at least 90% of its gross income from dividends, interest, certain
payments with respect to securities loans and gains from the sale or other
disposition of stock or securities or foreign currencies (including, but not
limited to, gains from forward foreign currency exchange contacts), or from
other income derived with respect to its business of investment in such stock,
securities, or currencies (the "Income Requirement").

     In addition to the foregoing requirements, at the close of each quarter of
its taxable year, at least 50% of the value of the Portfolio's assets must
consist of cash and cash items, U.S. government securities, securities of other
regulated investment companies, and securities of other issuers (as to which the
Portfolio has not invested more than 5% of the value of its total assets in
securities of such issuer and as to which the Portfolio does not hold more than
10% of the outstanding voting securities of such issuer), and no more than 25%
of the value of the Portfolio's total assets may be invested in the securities
of any one issuer (other than U.S. government securities and securities of other
regulated investment companies), or in two or more issuers which such Portfolio
controls and which are engaged in the same or similar trades or businesses.

     Distributions of net investment income will be taxable to shareholders as
ordinary income, regardless of whether such distributions are paid in cash or
are reinvested in shares.  Shareholders receiving any taxable distribution from
the Portfolio in the form of additional shares will be treated as receiving a
taxable distribution in an amount equal to the fair market value of the shares
received, determined as of the reinvestment date.

     The Portfolio intends to distribute to shareholders all of its net capital
gain for each taxable year.  Net capital gain is distributed as a capital gain
dividend and is taxable to shareholders as long-term capital gain, regardless of
the length of time the shareholder has held his shares, whether net capital gain
was recognized by the Portfolio prior to the date on which a shareholder
acquired shares of the Portfolio and whether the distribution was paid in cash
or reinvested in shares.

     It is expected that distributions from the Portfolio will generally not
qualify for the "dividends received" deduction for corporate shareholders.

     Ordinary income of individuals will be taxable at a maximum marginal rate
of 39.6%, but because of limitations on itemized deductions otherwise allowable
and the phase-out of personal exemptions, the maximum effective marginal rate of
tax for some taxpayers may be higher.  Long-term capital gains of individuals
are taxed at a maximum rate of 28%.  Capital gains and ordinary income of
corporate taxpayers are both taxed at a maximum rate of 35%.  Investors should
be aware that any loss realized upon the sale, exchange or redemption of shares
held for six months or less will be treated as a long-term capital loss to the
extent any capital gain dividends have been paid with respect to such shares.

                                      -43-
<PAGE>

     The Portfolio may engage in hedging or derivatives transactions involving
forward contracts, options and futures contracts and short sales.  Such
transactions will be subject to special provisions of the Code that, among other
things, may affect the character of gains and losses realized by the Portfolio
(that is, may affect whether gains or losses are ordinary or capital),
accelerate recognition of income of the Portfolio and defer recognition of
certain of the Portfolio's losses.  These rules could therefore affect the
character, amount and timing of distributions to shareholders.  In addition,
these provisions (1) will require the Portfolio to "mark-to-market" certain
types of positions in its portfolio (that is, treat them as if they were closed
out) and (2) may cause the Portfolio to recognize income without receiving cash
with which to pay dividends or make distributions in amounts necessary to
satisfy the Distribution Requirement and avoid the 4% excise tax (described
below).  The Portfolio intends to monitor its transactions, will make the
appropriate tax elections and will make the appropriate entries in its books and
records when it acquires any option, futures contract, forward contract or
hedged investment in order to mitigate the effect of these rules.

     If for any taxable year the Portfolio does not qualify as a regulated
investment company, all of its taxable income will be subject to tax at regular
corporate rates without any deduction for distributions to shareholders, and all
distributions will be taxable as ordinary dividends to the extent of the
Portfolio's current and accumulated earnings and profits.  Such distributions
will be eligible for the dividends received deduction in the case of corporate
shareholders.

     A 4% non-deductible excise tax is imposed on regulated investment companies
that fail to currently distribute specified percentages of their ordinary
taxable income and capital gain net income (excess of capital gains over capital
losses).  The Portfolio 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.

     The Fund will be required in certain cases to withhold and remit to the
United States Treasury 31% of dividends and gross sale proceeds paid to any
shareholder (i) who has provided either an incorrect tax identification number
or no number at all, (ii) who is subject to backup withholding by the Internal
Revenue Service for failure to report the receipt of interest or dividend income
properly, or (iii) who has failed to certify to the Fund that he is not subject
to backup withholding or that he is an "exempt recipient."

     Shareholders will be advised annually as to the federal income tax
consequences of distributions made by the Portfolio each year.

     The foregoing general discussion of federal income tax consequences is
based on the Code and the regulations issued thereunder as in effect on the date
of this Statement of Additional Information.  Future legislative or
administrative changes or court decisions may significantly change the
conclusions expressed herein, and any such changes or decisions may have a
retroactive effect with respect to the transactions contemplated herein.

                                      -44-
<PAGE>

     Although the Portfolio expects to qualify as a regulated investment company
and to be relieved of all or substantially all Federal income taxes, depending
upon the extent of its activities in states and localities in which its offices
are maintained, in which its agents or independent contractors are located or in
which it is otherwise deemed to be conducting business, the Portfolio may be
subject to the tax laws of such states or localities.  Shareholders should
consult their tax advisors about state and local tax consequences, which may
differ from the federal income tax consequences described above.

                    ADDITIONAL INFORMATION CONCERNING SHARES

     Each share of the Portfolio has a par value of $.001, represents an equal
proportionate interest in the Portfolio and is entitled to such dividends and
distributions earned on the Portfolio's assets as are declared in the discretion
of the Board of Trustees.  The Fund's shareholders are entitled to one vote for
each full share held and proportionate fractional votes for fractional shares
held, and will vote in the aggregate and not by class, except where otherwise
required by law or as determined by the Board of Trustees.  The Fund does not
currently intend to hold annual meetings of shareholders for the election of
trustees (except as required under the 1940 Act).

     Shares of the Fund have noncumulative voting rights and, accordingly, the
holders of more than 50% of the Fund's outstanding shares (irrespective of
Portfolio or class) may elect all of the trustees.  Shares have no preemptive
rights and only such conversion and exchange rights as the Board may grant in
its discretion.  When issued for payment as described in the Prospectus, shares
will be fully paid and non-assessable by the Fund.

     There will normally be no meetings of shareholders for the purpose of
electing trustees unless and until such time as required by law.  At that time,
the trustees then in office will call a shareholders meeting to elect trustees.
Except as set forth above, the trustees will continue to hold office and may
appoint successor trustees.  The Fund's Declaration of Trust provides that
meetings of the shareholders of the Fund will be called by the trustees upon the
written request of shareholders owning at least 10% of the outstanding shares
entitled to vote.

     Rule 18f-2 under the 1940 Act provides that any matter required by the
provisions of the 1940 Act or applicable state law, or otherwise, to be
submitted to the holders of the outstanding voting securities of an investment
company such as the Fund shall not be deemed to have been effectively acted upon
unless approved by the holders of a majority of the outstanding shares of each
investment portfolio affected by such matter.  Rule 18f-2 further provides that
an investment portfolio shall be deemed to be affected by a matter unless the
interests of each investment portfolio in the matter are substantially identical
or the matter does not affect any interest of the investment portfolio.  Under
the Rule, the approval of an investment advisory agreement, a distribution plan
subject to Rule 12b-1 under the 1940 Act or any change in a fundamental
investment policy would be effectively acted upon with respect to an investment

                                      -45-
<PAGE>

portfolio only if approved by a majority of the outstanding shares of such
investment portfolio.  However, the Rule also provides that the ratification of
the appointment of independent accountants, the approval of principal
underwriting contracts and the election of Trustees may be effectively acted
upon by shareholders of the Fund voting together in the aggregate without regard
to a particular investment portfolio.

     The proceeds received by the Portfolio for each issue or sale of its
shares, and all net investment income, realized and unrealized gain and proceeds
thereof, subject only to the rights of creditors, will be specifically allocated
to and constitute the underlying assets of the Portfolio.  The underlying assets
of the Portfolio will be segregated on the books of account, and will be charged
with the liabilities in respect to the Portfolio and with a share of the general
liabilities of the Fund.

     The Funds' Declaration of Trust authorizes the Board of Trustees, without
shareholder approval (unless otherwise required by applicable law), to:  (i)
sell and convey the assets belonging to a class of shares to another management
investment company for consideration which may include securities issued by the
purchaser and, in connection therewith, to cause all outstanding shares of such
class to be redeemed at a price which is equal to their net asset value and
which may be paid in cash or by distribution of the securities or other
consideration received from the sale and conveyance; (ii) sell and convert the
assets belonging to one or more classes of shares into money and, in connection
therewith, to cause all outstanding shares of such class to be redeemed at their
net asset value; or (iii) combine the assets belonging to a class of shares with
the assets belonging to one or more other classes of shares if the Board of
Trustees reasonably determines that such combination will not have a material
adverse effect on the shareholders of any class participating in such
combination and, in connection therewith, to cause all outstanding shares of any
such class to be redeemed or converted into shares of another class of shares at
their net asset value.  The Board of Trustees may authorize the termination of
any class of shares after the assets belonging to such class have been
distributed to its shareholders.

                                 MISCELLANEOUS

     Counsel.  The law firm of Simpson Thacher & Bartlett, 425 Lexington Avenue,
New York, New York 10017 serves as the Fund's counsel.

     Independent Accountants.  PricewaterhouseCoopers LLP, 2400 Eleven Penn
Center, Philadelphia, Pennsylvania 19103, which provides accounting and auditing
services, serves as the Fund's independent accountants.


     Control.  On August 19, 1999, PNC Bank held of record approximately 72% of
the Fund's outstanding shares, and may be deemed a controlling person of the
Fund under the 1940 Act.  PNC Bank is a national bank organized under the laws
of the United States.  All of the


                                      -46-
<PAGE>

capital stock of PNC Bank is owned by PNC Bancorp, Inc.  All of the capital
stock of PNC Bancorp, Inc. is owned by PNC Bank Corp., a publicly-held bank
holding company.

     Banking Laws.  Banking laws and regulations currently 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, controlling
or distributing the shares of a registered, open-end investment company
continuously engaged in the issuance of its shares, and prohibit banks generally
from underwriting securities, but such banking laws and regulations do not
prohibit such a holding company or affiliate or banks generally from acting as
investment adviser, administrator, transfer agent or custodian to such an
investment company, or from purchasing shares of such a company as agent for and
upon the order of customers.  BlackRock, BAI, PFPC and PNC Bank are subject to
such banking laws and regulations.  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.

     Should future legislative, judicial or administrative action prohibit or
restrict the activities of such companies in connection with the provision of
services on behalf of the Fund and the holders of its Shares, the Fund might be
required to alter materially or discontinue its arrangements with such companies
and change its method of operations with respect to its Shares.  It is not
anticipated, however, that any change in the Fund's method of operations would
affect its net asset value per share or result in a financial loss to any
investor.

     BlackRock, BAI, PFPC and PTC believe they may perform the services for the
Fund contemplated by their respective agreements with the Fund without violation
of applicable banking laws or regulations.  It should be noted, however, that
there have been no cases deciding whether bank and non-bank subsidiaries of a
registered bank holding company may perform services comparable to those that
are to be performed by these companies, and future changes in either Federal or
state statutes and regulations relating to permissible activities of banks and
their subsidiaries or affiliates, as well as further judicial or administrative
decisions or interpretations of present and future statutes and regulations,
could prevent these companies from continuing to perform such services for the
Fund.  If such were to occur, it is expected that the Board of Trustees would
recommend that the Fund enter into new agreements or would consider the possible
termination of the Fund.  Any new advisory or sub-advisory agreement would be
subject to shareholder approval.

     Shareholder Approvals.  As used in this Statement of Additional Information
and in the Prospectus, a "majority of the outstanding shares" means, with
respect to the approval of the Portfolio's investment advisory agreement, a
distribution plan or a change in a fundamental investment policy, the lesser of
(1) 67% of the shares of the Portfolio represented at a meeting at which the
holders of more than 50% of the outstanding shares of the Portfolio are present
in person or by proxy, or (2) more than 50% of the outstanding shares of the
Portfolio.

                                   APPENDIX A

     The following summarizes the ratings used for debt securities:

DESCRIPTION OF MOODY'S BOND RATINGS:

          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 "Aa" 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 "Aa" securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risks appear somewhat larger than in "Aaa"
securities.

          A - Bonds possess many favorable investment attributes and are to be
considered as upper medium grade obligations.  Factors giving security to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.

          Baa - Bonds considered medium-grade obligations, i.e., they are
neither highly protected nor poorly secured.  Interest payments and principal
security appear adequate for the present but certain protective elements may be
lacking or may be characteristically unreliable over any great length of time.
Such bonds lack outstanding investment characteristics and in fact have
speculative characteristics as well.

          Ba - Bonds that possess this rating provide questionable protection of
interest and principal and indicate some speculative elements.

          Note:  Those bonds in the Aa, A, Baa and Ba groups which Moody's
believes possess the strongest investment attributes are designated by the
symbols Aa1, A1, Baa1 and Ba1.

DESCRIPTION OF S&P BOND RATINGS:

          AAA - This designation represents the highest rating assigned by
Standard & Poor's to a debt obligation and indicates an extremely strong
capacity to pay interest and repay principal.

                                      A-1
<PAGE>

          AA - Debt is considered to have a very strong capacity to pay interest
and repay principal and differs from AA issues only in small degree.

          A - Debt is considered to have a strong capacity to pay interest and
repay principal although such issues are somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than debt in
higher-rated categories.

          BBB - Debt is regarded as having an adequate capacity to pay interest
and repay principal.  Whereas such issues normally exhibit adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher-rated categories.

          BB - Debt is regarded, on balance, as predominantly speculative with
respect to capacity to pay interest and repay principal in accordance with the
terms of the obligation.  While such debt will likely have some quality and
protective characteristics, these are outweighed by large uncertainties or major
risk exposures to adverse conditions.  Debt has less near-term vulnerability to
default than other speculative issues.  However, it faces major ongoing
uncertainties or exposure to adverse business, financial or economic conditions
which could lead to inadequate capacity to meet timely interest and principal
payments.  The "BB" rating category is also used for debt subordinated to senior
debt that is assigned an actual or implied "BBB-" rating.

          Standard & Poor's letter ratings may be modified by the addition of a
plus or minus sign, which is used to show relative standing within the major
rating categories, except in the AAA category.


DESCRIPTION OF DUFF & PHELPS' BOND RATINGS:

          AAA - Bonds rated AAA are of the highest credit quality.  The risk
factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.

          AA - Bonds rated AA have high credit quality with strong protection
factors.  Risk is modest.

          A - Bonds rated A have average but adequate protection factors.  Risk
factors are greater and more variable in times of economic stress than AA or AA.

          BBB - Bonds rated BBB exhibit below average protection factors, but
still considered sufficient for prudent investment.  Considerable variability in
risk is present during economic cycles.

          BB - Bonds rated BB are below investment grade, but deemed likely to
meet obligations when due.

                                      A-2
<PAGE>

          Duff & Phelps' letter ratings may be modified by the addition of a
plus or minus sign, which is used to show relative standing within the major
rating categories, except in the AAA category.


DESCRIPTION OF FITCH BOND RATINGS:

          AAA - Bonds rated AAA are considered investment grade and of the
highest quality.  The ability to pay interest and principal is exceptionally
strong and unlikely to be affected by reasonably foreseeable events.

          AA - Bonds rated AA are considered investment grade and very high
credit quality.

          A - Bonds rated A are considered investment grade and of high credit
quality.  The ability to pay interest and principal is strong, but may be
vulnerable to adverse changes in economic conditions and circumstances than
bonds with higher ratings.

          BBB - Bonds rated BBB are considered investment grade and satisfactory
credit quality.  The likelihood that these bonds will fall below investment
grade, however, is higher than for bonds with higher ratings.

          BB - Bonds rated BB are considered speculative.  The ability to pay
interest and principal may be affected over time by adverse economic changes.

          Fitch's letter ratings may be modified by the addition of a plus or
minus sign, which is used to show relative standing within the major rating
categories, except in the AAA category.

                                   APPENDIX B

                      GENERAL CHARACTERISTICS AND RISKS OF
                  ADDITIONAL INVESTMENT MANAGEMENT TECHNIQUES

          In order to manage the risk of its securities portfolio, including
duration management, or to enhance income or gain as described above, the
Portfolio will engage in Additional Investment Management Techniques.  The
Portfolio will engage in such activities in the Adviser's discretion, and may
not necessarily be engaging in such activities when movements in interest rates
that could affect the value of the assets of the Portfolio occur.  The
Portfolio's ability to pursue certain of these strategies may be limited by
applicable regulations of the CFTC and the federal income tax requirements
applicable to regulated investment companies.

Put and Call Options on Securities and Indices

          The Portfolio may purchase and sell put and call options on securities
and indices.  A put option gives the purchaser of the option the right to sell
and the writer the obligation to buy the underlying security at the exercise
price during the option period.  The Portfolio may also purchase and sell
options on stock indices ("index options").  Index options are similar to
options on securities except that, rather than taking or making delivery of
securities underlying the option at a specified price upon exercise, an index
option gives the holder the right to receive cash upon exercise of the option if
the level of the stock index upon which the option is based is greater, in the
case of a call, or less, in the case of a put, than the exercise price of the
option.  The purchase of a put option on a debt security could protect the
Portfolio's holdings in a security or a number of securities against a
substantial decline in the market value.  A call option gives the purchaser of
the option the right to buy and the seller the obligation to sell the underlying
security or index at the exercise price during the option period or for a
specified period prior to a fixed date.  The purchase of a call option on a
security could protect the Portfolio against an increase in the price of a
security that it intended to purchase in the future.  In the case of either put
or call options that it has purchased, if the option expires without being sold
or exercised, the Portfolio will experience a loss in the amount of the option
premium plus any related commissions.  When the Portfolio sells put and call
options, it receives a premium as the seller of the option.  The premium that
the Portfolio receives for selling the option will serve as a partial hedge, in
the amount of the option premium, against changes in the value of the securities
in its portfolio.  During the term of the option, however, a covered call seller
has, in return for the premium on the option, given up the opportunity for
capital appreciation above the exercise price of the option if the value of the
underlying security increases, but has retained the risk of loss should the
price of the underlying security decline.  Conversely, a secured put seller
retains the risk of loss should the market value of the underlying security
decline below the exercise price of the option, less the premium received on the
sale of the option.  The Portfolio is authorized to purchase and sell exchange
listed options and over-the-counter options ("OTC Options") which are privately
negotiated with the counterparty.  Listed options are issued by the Options
Clearing Corporation ("OCC") which guarantees the performance of the obligations
of the parties to such options.

                                      B-1
<PAGE>

          The Portfolio's ability to close out its position as a purchaser or
seller of an exchange-listed put or call option is dependent upon the existence
of a liquid secondary market on option exchanges.  Among the possible reasons
for the absence of a liquid secondary market on an exchange are:  (i)
insufficient trading interest in certain options; (ii) restrictions on
transactions imposed by an exchange; (iii) trading halts, suspensions or other
restrictions imposed with respect to particular classes or series of options or
underlying securities; (iv) interruption of the normal operations on an
exchange; (v) inadequacy of the facilities of an exchange or OCC to handle
current trading volume; or (vi) a decision by one or more exchanges to
discontinue the trading of options (or a particular class or series of options),
in which event the secondary market on that exchange (or in that class or series
of options) would cease to exist, although outstanding options on that exchange
that had been listed by the OCC as a result of trades on that exchange would
generally continue to be exercisable in accordance with their terms.  OTC
Options are purchased from or sold to dealers, financial institutions or other
counterparties which have entered into direct agreements with the Portfolio.
With OTC Options, such variables as expiration date, exercise price and premium
will be agreed upon between the Portfolio and the counterparty, without the
intermediation of a third party such as the OCC.  If the counterparty fails to
make or take delivery of the securities underlying an option it has written, or
otherwise settle the transaction in accordance with the terms of that option as
written, the Portfolio would lose the premium paid for the option as well as any
anticipated benefit of the transaction.  As the Portfolio must rely on the
credit quality of the counterparty rather than the guarantee of the OCC, it will
only enter into OTC Options with counterparties with the highest long-term
credit ratings, and with primary United States government securities dealers
recognized by the Federal Reserve Bank of New York.

          The hours of trading for options on debt securities may not conform to
the hours during which the underlying securities are traded.  To the extent that
the option markets close before the markets for the underlying securities,
significant price and rate movements can take place in the underlying markets
that cannot be reflected in the option markets.

Futures Contracts and Related Options

          Characteristics.  The Portfolio may sell financial futures contracts
or purchase put and call options on such futures as a hedge against anticipated
interest rate changes or other market movements.  The sale of a futures contract
creates an obligation by the Portfolio, as seller, to deliver the specific type
of financial instrument called for in the contract at a specified future time
for a specified price.  Options on futures contracts are similar to options on
securities except that an option on a futures contract gives the purchaser the
right in return for the premium paid to assume a position in a futures contract
(a long position if the option is a call and a short position if the option is a
put).

          Margin Requirements.  At the time a futures contract is purchased or
sold, the Portfolio must allocate cash or securities as a deposit payment
("initial margin").  It is expected

                                      B-2
<PAGE>

that the initial margin that the Portfolio will pay may range from approximately
1% to approximately 5% of the value of the securities or commodities underlying
the contract.  In certain circumstances, however, such as periods of high
volatility, the Portfolio may be required by an exchange to increase the level
of its initial margin payment.  Additionally, initial margin requirements may be
increased generally in the future by regulatory action.  An outstanding futures
contract is valued daily and the payment in cash of "variation margin" may be
required, a process known as "marking to the market."  Transactions in listed
options and futures are usually settled by entering into an offsetting
transaction, and are subject to the risk that the position may not be able to be
closed if no offsetting transaction can be arranged.

          Limitations on Use of Futures and Options on Futures.  The Portfolio's
use of futures and options on futures will in all cases be consistent with
applicable regulatory requirements and in particular the rules and regulations
of the CFTC.  Under such regulations the Portfolio currently may enter into such
transactions without limit for bona fide hedging purposes, including risk
management and duration management and other portfolio strategies.

          The Portfolio will not enter into a futures contract or related option
if, immediately thereafter, the sum of the amount of its initial deposits and
premiums on open contracts and options would exceed 5% of the Portfolio's
liquidation value, i.e. net assets (taken at current value); provided, however,
that in the case of an option that is in-the-money at the time of the purchase,
the in-the-money amount may be excluded in calculating the 5% limitation.  Also,
when required, a segregated account of cash or cash equivalents will be
maintained and marked to market in an amount equal to the market value of the
contract.  The Portfolio reserves the right to comply with such different
standard as may be established from time to time by CFTC rules and regulations
with respect to the purchase or sale of futures contracts or options thereon.

          Segregation and Cover Requirements.  Futures contracts, interest rate
swaps, caps, floors and collars and listed options on securities, indices and
futures contracts sold by the Portfolio are subject to segregation and coverage
requirements of either the CFTC or the SEC, with the result that, if the
Portfolio does not hold the security or futures contract underlying the
instrument, the Portfolio will be required to segregate on an ongoing basis with
its custodian, cash, U.S. government securities, or other liquid debt
obligations in an amount at least equal to the Portfolio's obligations with
respect to such instruments.  Such amounts fluctuate as the obligations increase
or decrease.  The segregation requirement can result in the Portfolio
maintaining securities positions it would otherwise liquidate, segregating
assets at a time when it might be disadvantageous to do so or otherwise restrict
portfolio management.

Item 24.  Persons Controlled by or under Common Control with the Fund.

          None.

Item 25.  Indemnification

          Indemnification of Registrant's principal underwriter against certain
losses is provided for in Section 7 of the Distribution Agreement incorporated
by reference herein as Exhibit 5(a).  Indemnification of Registrant's Custodian,
Transfer Agent and Administrators is provided for, respectively, in Section 22
of the Custodian Agreement incorporated by reference herein as Exhibit 7(a),
Section 17 of the Transfer Agency Agreement incorporated by reference herein as
Exhibit 8(c) and Section 11 of the Administration Agreement incorporated by
reference herein as Exhibit 8(a).  Registrant intends to obtain from a major
insurance carrier a trustees' and officers' liability policy covering certain
types of errors and omissions.  In addition, Section 9.3 of the Registrant's
Declaration of Trust incorporated by reference herein as Exhibit 1(a) provides
as follows:

          Indemnification of Trustees, Officers, Representatives and Employees.
          --------------------------------------------------------------------
     The Trust shall indemnify each of its Trustees against all liabilities and
     expenses (including amounts paid in satisfaction of judgments, in
     compromise, as fines and penalties, and as counsel fees) reasonably
     incurred by him in connection with the defense or disposition of any
     action, suit or other proceeding, whether civil or criminal, in which he
     may be involved or with which he may be threatened, while as a Trustee or
     thereafter, by reason of his being or having been such a Trustee except
                                                                      ------
     with respect to any matter as to which he shall have been adjudicated to
     have acted in bad faith, willful misfeasance, gross negligence or reckless
     disregard of his duties, provided that as to any matter disposed of by a
                              --------
     compromise payment by such person, pursuant to a consent decree or
     otherwise, no indemnification either for said payment or for any other
     expenses shall be provided unless the Trust shall have received a written
     opinion from independent legal counsel approved by the Trustees to the
     effect that if either the matter of willful misfeasance, gross negligence
     or reckless disregard of duty, or the matter of bad faith had been
     adjudicated, it would in the opinion of such counsel have been adjudicated
     in favor of such person.  The rights accruing to any person under these
     provisions shall not exclude any other right to which he may be lawfully
     entitled, provided that no person may satisfy any right of indemnity or
               --------
     reimbursement hereunder except out of the property of the Trust.  The
     Trustees may make advance payments in connection with the indemnification
     under this Section 9.3, provided that the indemnified person shall have
                             --------
     given a written undertaking to

                                      C-11
<PAGE>

     reimburse the Trust in the event it is subsequently determined that he is
     not entitled to such indemnification.

          The Trustee shall indemnify officers, representatives and employees of
     the Trust to the same extent that Trustees are entitled to indemnification
     pursuant to this Section 9.3.

          Insofar as indemnification for liability arising under the Securities
Act of 1933 may be permitted to trustees, officers and controlling persons of
Registrant pursuant to the foregoing provisions, or otherwise, Registrant has
been advised that in the opinion of the Securities and Exchange Commission 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 trustee, officer or controlling person of Registrant in the successful
defense of any action, suit or proceeding) is asserted by such trustee, 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.

          Section 9.6 of the Registrant's Declaration of Trust, filed herein as
Exhibit 1(a), also provides for the indemnification of shareholders of the
Registrant.  Section 9.6 states as follows:

          Indemnification of Shareholders.  In case any Shareholder or former
          -------------------------------
     Shareholder shall be held to be personally liable solely by reason of his
     being or having been a Shareholder 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 classes of
     Shares with the same alphabetical designation as that of the Shares owned
     by such Shareholder to be held harmless from and indemnified against all
     loss and expense arising from such liability.  The Trust shall, upon
     request by the Shareholder, assume the defense of any claim made against
     any Shareholder for any act or obligations of the Trust and satisfy any
     judgment thereon from such assets.

                             Distribution Agreement
                             ----------------------

     Agreement dated as of June 25, 1999 between BLACKROCK FUNDS, a
Massachusetts business trust (the "Company"), and BLACKROCK 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 3 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.   Delivery of Documents.  The Company has furnished or will furnish the
          ----------------------
Distributor with copies, properly certified or authenticated, of each of the
following documents and will deliver to it all future amendments and
supplements, if any:

          a.  The Company's Declaration of Trust, filed with the Secretary of
State of the Commonwealth of Massachusetts on December 22, 1988, as amended (the
"Charter");

          b.  The Company's Amended and Restated Code of Regulations, as amended
and supplemented ("Code");
<PAGE>

          c.  Resolutions of the Company's Board of Trustees authorizing the
execution and delivery of this Agreement;

          d.  The Company's most recent amendment to its Registration Statement
under the Securities Act of 1933, as amended (the "1933 Act"), and the 1940 Act
on Form N-1A as filed with the Securities and Exchange Commission (the
"Commission"), relating to its Funds (the Registration Statement, as presently
in effect and as amended or supplemented from time to time, is herein called the
"Registration Statement");

          e.  The Company's most recent Prospectuses and Statements of
Additional Information and all amendments and supplements thereto (such
Prospectuses and Statements of Additional Information and supplements thereto,
as presently in effect and as from time to time amended and supplemented, are
herein called the "Prospectuses"); and

          f.  The Company's Amended and Restated Distribution and Service Plan
and related Distribution and Service Agreements relating to the Company's
respective share classes.

     3.   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 broker-dealer
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 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 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 series thereof.

          c.  In performing all of its services and duties as Distributor, the
Distributor will act in conformity with the Charter, Code, Prospectuses and
resolutions and other instructions of the Company's Board of Trustees and will
comply with the requirements of 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 printing and distributing
any Prospectus (including any supplement thereto) to persons who are not
shareholders; provided, however, that the Distributor shall not be obligated to
              --------  -------
bear the expenses incurred by the
<PAGE>

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 without reasonable cause.

     4.   Payments Relating to Distribution Plans.  Payments by the Company
          ----------------------------------------
relating to any distribution plan within the meaning of Rule 12b-1 under the
1940 Act (a "Plan") adopted by the Company's Board of Trustees may be payable to
the Distributor or its assignees, all in accordance with the terms and
conditions of such Plan.

     5.   Payments of Sales Charges.  Any front-end sales charges or deferred
          --------------------------
sales charges payable in connection with purchases of Series A Investor Class
Shares, Series B Investor Class Shares and Series C Investor Class Shares,
respectively, shall be payable to the Distributor or its assignees, all in
accordance with the Company's Prospectus.

     6.   Forfeiture of Sales Charges.   If any shares sold by the Distributor
          ----------------------------
under the terms of this Agreement are redeemed or repurchased by the Fund or by
the Distributor as agent or are tendered for redemption within seven business
days after the date of confirmation of the original purchase of said shares, the
Distributor shall forfeit the amount above the net asset value received by it in
respect of such shares, provided that the portion, if any, of such amount re-
allowed by the Distributor to broker-dealers or other persons shall be repayable
to the Company only to the extent recovered by the Distributor from the broker-
dealer or other person concerned. The Distributor shall include in the form of
agreement which such broker-dealers and other persons a corresponding provision
for the forfeiture by them of their concession with respect to shares sold by
them or their principals and redeemed or repurchased by the Company or by the
Distributor as agent (or tendered for redemption) within seven business days
after the date of confirmation of such initial purchases.

     7.   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.


     8.   Proprietary and Confidential Information.  The Distributor agrees on
          ----------------------------------------
<PAGE>

behalf of itself and its employees to treat confidentially and as proprietary
information of the Company all 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.

     9.   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 9 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 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
<PAGE>

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 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 9 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
Prospectus or any 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, which
statement or omission was made in reliance upon and in conformity with
information furnished in writing to the Company or any of its several officers
and trustees by or on behalf of the Distributor or either of the Company's co-
administrators specifically for inclusion therein, and will reimburse the
Company and its several officers, trustees and such controlling persons for any
legal or other expenses reasonably incurred by any of them in investigating,
defending or preparing to defend any such action, proceeding or claim.

          e. The obligations of each Fund under this Section 9 shall be the
several (and not the joint or joint and several) obligation of each Fund.

     10.  Duration and Termination.  This Agreement shall become effective upon
          ------------------------
its execution as of the date first written above and, unless sooner terminated
as provided herein, shall continue until March 31, 2000. Thereafter, if not
terminated, this Agreement shall continue automatically for successive terms of
one year, provided that such continuance is specifically approved at least
annually (a) by a vote of a majority of those members of the Company's Board of
Trustees who are not parties to this Agreement or "interested persons" of any
such party, cast in person at a meeting called for the purpose of voting on such
approval, and (b) by the Company's Board of Trustees or by vote of a "majority
of the outstanding voting securities" of the Company; provided, however, that
                                                      --------  -------
this Agreement may be terminated by the Company at any time, without the payment
of any penalty, by vote of a majority of the entire
<PAGE>

Board of Trustees or by a vote of a "majority of the outstanding voting
securities" of the Company on 60-days' written notice to the Distributor, or by
the Distributor at any time, without the payment of any penalty, on 90-days'
written notice to the Company.  This Agreement will automatically and
immediately terminate in the event of its "assignment." (As used in this
Agreement, the terms "majority of the outstanding voting securities,"
"interested person" and "assignment" shall have the same meanings as such terms
have in the 1940 Act.)

     11.  Amendment of this Agreement.  No provision of this Agreement may be
          ---------------------------
changed, waived, discharged or terminated orally, but only by an instrument in
writing signed by the patty against which an enforcement of the change, waiver,
discharge or termination is sought.

     12.  Notices.  Notices of any kind to be given to the Company hereunder by
          -------
the Distributor shall be in writing and shall be duly given if mailed or
delivered to the Company at 400 Bellevue Parkway, Wilmington, Delaware 19809,
with a copy to Karen H. Sabath, 345 Park Avenue, New York, New York 10154, or at
such other address or to such individual as shall be so specified by the Company
to the Distributor. Notices of any kind to be given to the Distributor hereunder
by the Company shall be in writing and shall be duly given if mailed or
delivered to BlackRock Distributors, Inc., Four Falls Corporate Center, 6th
Floor, West Conshohocken, Pennsylvania 19428, Attention: Philip H. Rinnander, or
at such other address or to such other individual as shall be so specified by
the Distributor to the Company.

     13.  Miscellaneous.
          -------------

          a.  The captions in this Agreement are included for convenience of
reference only and in no way define or delimit any of the provisions hereof or
otherwise affect their construction or effect. If any provision of this
Agreement shall be held or made invalid by a court decision, statute, rule or
otherwise, the remainder of this Agreement shall not be affected thereby. This
Agreement shall be binding upon and shall inure to the benefit of the parties
hereto and their respective successors.

          b.  The names "BlackRock Funds" and "Trustees of BlackRock Funds"
refer specifically to the trust created and the Trustees, as trustees but not
individually or personally, acting from time to time under a Declaration of
Trust dated December 22, 1988, which is hereby referred to and a copy of which
is on file at the office of the Secretary of the Commonwealth of Massachusetts
and at the principal office of the Company. The obligations of "BlackRock Funds"
entered into in the name or on behalf thereof by any of the Trustees, officers,
representatives or agents are not made individually, but in such capacities, and
are not binding upon any of the Trustees, shareholders, representatives or
agents of the Company personally, but bind only the Trust property (as defined
in the Declaration of Trust), and all persons dealing with any Fund or class of
shares of the Company must look solely to the Trust property belonging to such
Fund or class for the enforcement of any claims against the Company.

     14.  Counterparts.  This Agreement may be executed in counterparts, all of
          ------------
 which together shall constitute one and the same instrument.

   Re:  Shares of Beneficial Interest, Class NN-3 (the "Class").
        --------------------------------------------------------

Ladies and Gentlemen:

          We have acted as special Massachusetts counsel for BlackRock Funds,
a  Massachusetts business trust (the "Trust").  You have informed us that
you intend to register under the Securities Act of 1933, as amended (the "Act"),
and offer and sell from time to time your shares of beneficial interest, $.001
par value, of the Class ("Shares").

          In connection with this opinion, we have examined:

          (i)   A copy of your Declaration of Trust dated as of December 22,
                1988, as amended (the "Declaration of Trust").

          (ii)  A certificate of the Secretary of State of the Commonwealth of
                Massachusetts certifying as to your authority to exercise in the
                Commonwealth all of the powers recited in the Declaration of
                Trust and to transact business in the Commonwealth.

          (iii) A copy of your Code of Regulations (the "Code of Regulations"),
                certified by your Secretary.

          (iv)  A certificate of your Secretary dated August 11, 1999 as to
                certain actions of the trustees of the Trust (including their
                due adoption of resolutions establishing the Class and
                authorizing the issuance of Shares in accordance with your
                registration statement under the Act (the "Registration
                Statement"), the Declaration of Trust and the Code of
                Regulations and applicable law from time to time after the
                effective date under the Act of the Post-Effective Amendment to
                the Registration Statement that is filed to register the Shares
                (the "Post-Effective Amendment")), and certifying, among other
                things, that the original Declaration of Trust was executed
                within the Commonwealth of Massachusetts and that you have
                maintained an office in Massachusetts since your organization.

<PAGE>

          In our examination, we have assumed the genuineness of all signatures,
the legal capacity of all natural persons, the authenticity of all documents
submitted to us as originals, the conformity to the original documents of all
documents submitted to us as certified or photostatic copies, and the
authenticity of such original documents.

          We have made such examination of Massachusetts law as we have deemed
relevant for purposes of this opinion.  We express no opinion as to the effect
of laws, rules or regulations of any state or jurisdiction other than the
Commonwealth of Massachusetts.

          Based on the forgoing, we are of the opinion that the issue and sale,
after the effective date under the Act of the Post-Effective Amendment, of an
unlimited number of Shares has been duly authorized under Massachusetts law, and
that, upon the original issue and sale after such effective date of any of such
authorized Shares in accordance with the Registration Statement and the
requirements of the Declaration of Trust and the Code of Regulations and
applicable law, and upon receipt by the Trust of the consideration therefor
specified in the Registration Statement as from time to time in effect (which
consideration shall in each case be at least equal to the applicable net asset
value and the par value of the Shares), the Shares so issued will be validly
issued, fully paid and nonassessable by the Trust.

          Under Massachusetts law, shareholders of a Massachusetts business
trust could, under certain circumstances, be held personally liable for the
obligations of the trust.  However, the Declaration of Trust disclaims
shareholder liability for acts or obligations of the Trust and requires that
notice of such disclaimer be given in every note, bond, contract, order or other
undertaking issued by or on behalf of the Trust or its Trustees, and in the
stationery used by the Trust.  The Declaration of Trust provides for
indemnification out of the assets of the Trust belonging to the class(es) of
shares owned by such shareholder (and other classes having the same alphabetical
designation) for all loss and expense of any shareholder held personally liable
solely by reason of his or her being or having been a shareholder.  Thus, the
risk of a shareholder's incurring financial loss on account of shareholder
liability is limited to circumstances in which the relevant class of shares
itself (and other classes having the same alphabetical designation) would be
unable to meet its obligations.

          We understand that this opinion is to be used in connection with the
registration of an indefinite number of Shares for offering and sale pursuant to
the Act.  We consent to the filing of this opinion with and as part of the
Registration Statement (File No. 33-26305).

                                         Very truly yours,
                                         /s/ Ropes & Gray

                                  (the "Fund")

AMENDED AND RESTATED PLAN PURSUANT TO RULE 18f-3 FOR OPERATION OF

                       A MULTI-CLASS DISTRIBUTION SYSTEM
                  ------------------------------------------


                                I. INTRODUCTION
                                ---------------


          On February 23, 1995, the Securities and Exchange Commission (the
"Commission") promulgated Rule 18f-3 under the Investment Company Act of 1940,
as amended (the "1940 Act"), which permits the creation and operation of a
multi-class distribution system without the need to obtain an exemptive order
under Section 18 of the 1940 Act.  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 the differences among the classes, including the various
services offered to shareholders, the different distribution arrangements for
each class, the methods for allocating expenses relating to those differences
and any conversion features or exchange privileges.  Previously, the Fund
operated a multi-class distribution system pursuant to an exemptive order
granted by the Commission on August 9, 1994.  On September 29, 1995, the Board
of Trustees of the Fund authorized the Fund to operate its current multi-class
distribution system in compliance with Rule 18f-3.  This Plan pursuant to Rule
18f-3 became effective on October 6, 1995 when it was filed with the Commission,
was amended and restated as of February 13, 1997 and May 1, 1998, and is hereby
amended and restated as of August 11, 1999.

                           II. ATTRIBUTES OF CLASSES
                           -------------------------

A.   Generally
     ---------

          Each investment portfolio of the Fund (each a "Portfolio" and,
collectively, the "Portfolios") may offer seven classes of shares:  Service
Shares;  Series A Investor Shares;  Series B Investor Shares;  Series C Investor
Shares;  Institutional Shares;  BlackRock Shares; and (vii) Hilliard Lyons
Shares ("HL Shares").

          In general, shares of each class shall be identical except for
different expense variables (which will result in different yields or total
returns for each class), certain related rights and certain shareholder
services.  More particularly, Series A Investor, Series B Investor, Series C
Investor, Service, Institutional, BlackRock and HL Shares of each Portfolio
shall represent equal pro rata interests in the assets of the particular
Portfolio, and shall be identical in all

                                                                               2


respects, except for: (a) the impact of (i) distribution, shareholder servicing
and shareholder processing expenses under the Fund's Amended and Restated
Distribution and Service Plan assessed to each particular share class; (ii)
transfer agency and certain administration expenses assessed from time to time
to particular share classes; and (iii) any other expenses identified from time
to time that should be properly allocated to each particular share class so long
as any changes in expense allocations are reviewed and approved by a vote of the
Board of Trustees, including a majority of the non-interested trustees; (b) the
fact that each class shall vote separately on any matter submitted to
shareholders that pertains to (i) the Fund's Amended and Restated Distribution
and Service Plan applicable to such class and (ii) the class expenses borne by
such class; (c) the exchange privileges and/or conversion features of each class
of shares; (d) the sales charge(s) applicable to certain classes of shares; (e)
the designation of each class of shares of a Portfolio; and (f) the different
shareholder services relating to each class of shares.

Shares of a Portfolio shall automatically be converted to (a) Service Shares of

Shares of such Portfolio is acting on the holder's behalf or (b) Series A

of dividends or distributions, a proportionate amount of Institutional Shares of
such Portfolio that were acquired through reinvestment of dividends or
distributions will likewise automatically convert to Service Shares or Series A
Investor Shares of the same Portfolio, as appropriate.
