                       (A CALIFORNIA LIMITED PARTNERSHIP)

David R. Wilmerding, Jr.
     Chairman

                                                                February 1, 2007
Fellow Partner:

     Enclosed is the Annual Report of Chestnut Street Exchange Fund for the year
ended December 31, 2006.

     Our Fund earned $6.88 per share of net investment income for a share
outstanding throughout 2006, compared to $6.19 per share earned in 2005. The
increase in dividends paid by portfolio securities of over $358,000, minus a
small reduction in interest income and an increase in expenses distributed over
a smaller number of shares outstanding, account for the increase in per share
earnings in 2006. Increases in expenses are largely attributable to insurance
and the costs of the partners meeting.

     After providing for the January 2007 distribution, the net asset value per
partnership share at December 31, 2006 was $377.68. The net asset value at
September 30, 2006, the date of our last report, was $367.62.

     During the fourth quarter of 2006, a stock split by Emerson Electric Co.
added 90,556 shares and 7,191 shares of Idearc, Inc. were distributed by Verizon
Communications, Inc.

     Additional information required by Securities and Exchange Commission
regulations is enclosed.

     Data on the equity markets, on certain holdings and on the performance of
our Fund since inception, including comparisons to leading stock market indices,
appear in the accompanying Investment Adviser's Report.

     Your comments or questions concerning Chestnut Street Exchange Fund are
welcomed.

                                           Yours sincerely,

                                           -s- David R. Wilmerding, Jr.

                                           David R. Wilmerding, Jr.


                          INVESTMENT ADVISER'S REPORT

U.S. EQUITY MARKET REVIEW

     U.S. equity markets continued their steady advance from July lows to close
out 2006 on a very positive note. All broad indices appreciated substantially
during the fourth quarter, with the small cap Russell 2000(R) Index (+8.9%) once
again outperforming indices comprised of larger companies. The Dow Jones
Industrial Average rose 7.4%, hitting its all-time high during the period, and
the S&P 500(R) Index gained 6.7%. Corporate profit growth, significant share
buybacks, low interest rates and active private equity funds were all major
catalysts that contributed to the impressive gains generated by the US stock
markets. 2006 marks the fourth straight year of gains for US equities following
the bear market of 2000 through 2002.

     The Federal Reserve continued to hold rates unchanged at its two meetings
during the fourth quarter. This policy continues to be validated as moderating
economic fundamentals and falling crude oil prices have eased investor concern
over potentially accelerating inflationary pressures. In its most recent
statement, the Federal Reserve indicated some further policy firming may be
needed to address inflation risks but emphasized that the extent and timing of
any such tightening will be data dependent.

     Standard & Poor's recently reported that fourth quarter operating earnings
are on pace to produce the lowest year-over-year gain in more than four and a
half years. This quarter could potentially mark the first single digit
year-over-year earnings increase since the first quarter of 2002, indicating
that economic growth may be slowing. Investors will keep a watchful eye on this
prospective development as softening economic numbers and weaker pricing power
could play a major role in the Federal Reserve's decision to begin easing rates.

     Large cap stocks underperformed both small and mid cap stocks during the
final quarter of 2006. For the year, large caps finished behind both small caps
and mid caps. The performance gap between large cap value and large cap growth
widened again during the fourth quarter and the Russell 1000 Value(R) Index
finished the year up 22.2% compared to a gain of 9.1% for the Russell 1000
Growth(R) Index.

     At the sector level, materials and energy were the best performing sectors
in the quarter, gaining 11.5% and 11.2%, respectively. In contrast, health care
was the notable laggard, gaining only 1.3%. Weakness in health care resulted
from a number of members of the incoming Democratic congress listing health care
reform as a top issue. The party's new position of power has created uncertainty
among health care investors as many Democrats are eager to give the government
more control over the drug industry. Materials outperformed the broader market
in the fourth quarter after posting a slight loss during the third quarter. The
reversal among materials was led by momentum in earnings expectations and strong
product demand among key names within the industry.

     With the Federal Reserve currently on the sidelines, the market will likely
continue to take its cue from inflation data reports and forward-looking
guidance issued by companies. At the same time, although the housing market
appears to be stabilizing, investors remain concerned as to the potential
spill-over effects from the recent housing market recession. Although November
housing data was encouraging, it is far from certain that the housing slump is
over. Looking forward to 2007, the biggest question now facing the market is not
whether the economy will slow, but to what degree.

                    INVESTMENT ADVISER'S REPORT (CONTINUED)

PERFORMANCE SUMMARY

     Chestnut Street Exchange Fund returned 3.47% in the fourth quarter, and
finished the year up 14.13%. Despite the solid absolute performance, the Fund
was unable to keep pace with the S&P 500(R), which gained 6.69% in the fourth
quarter, and 15.79% for the year. Sector allocation and the Fund's sizable
overweight position in Intel accounted for the majority of the benchmark
relative underperformance for the year. The largest individual contributors on a
relative basis included Merck and Abbott Laboratories in health care, Bank of
America in financials, and Schlumberger in the energy sector.

PORTFOLIO REVIEW

     The source of the portfolio's absolute gains continues to be diverse, as a
number of names posted healthy gains during the fourth quarter. Nine of the ten
major sectors in the portfolio produced positive returns during the quarter,
with the exception being information technology. Exxon Mobil was the top
absolute contributor to performance during the quarter as shares gained 14.2% in
response to better-than expected earnings, which topped $10 billion, or $1.77
per share. On a relative basis, top performers included specialty chemicals and
materials manufacturer Cabot Corp in the materials sector and Comcast Corp in
consumer discretionary. Cabot has benefited from strong demand in all of its
business units and from the positive effect of high plant utilization, while
Comcast shares have been bolstered by demand for the firm's bundled subscription
package, which includes Cable TV, Internet and telephone service all under one
bill.

     In contrast, notable detractors from relative performance during the fourth
quarter included Intel, Wells Fargo and Johnson & Johnson. Large positions in
these stocks hurt the portfolio's active return. With average active weights of
approximately 6.8%, 6.4%, and 9.1% respectively, these three positions tend to
have a major impact on Fund results. While Wells Fargo and Intel did not
experience dramatic price declines, their position sizes in the portfolio made
them the top two detractors. Similarly, Johnson & Johnson posted a positive
gain, but like other health care stocks, could not keep pace with some of the
more cyclical groups.

     Activity within the portfolio was limited during the fourth quarter. We
continued to use positions in Freescale Semiconductor and Johnson & Johnson to
meet redemptions in kind. Shares of Intel, the cell-phone chipmaker surged after
the company agreed to be bought by a private equity consortium led by Blackstone
Group for $17.6 billion. The deal's size surpassed that of previous buyouts in
the technology sector, making it the biggest ever. We have continued to reduce
our position in Johnson & Johnson to enhance diversification in the portfolio.
At year end, shares of Johnson & Johnson accounted for approximately 10.0% of
the overall portfolio. While shares of Johnson & Johnson posted mid single digit
gains in 2006, we continue to believe the firm faces a number of headwinds
moving into 2007. Lastly, there is one new stock in the portfolio as the result
of a spinoff. Verizon Communications completed the spinoff of its U.S. yellow
pages business during November. The new firm, named Idearc, began trading on
November 20th.

     The performance data represent past performance and should not be
considered indicative of future performance which will fluctuate with changes in
market conditions. These performance fluctuations will cause an investor's
shares, when redeemed, to be worth more or less than their original cost.

     In addition, the data does not reflect the deduction of taxes that a
shareholder would pay on distributions or redemption of Fund shares.

(1) The chart assumes a hypothetical $10,000 initial investment in the Fund made
    on January 1, 1997 and reflects Fund expenses. Investors should note that
    the Fund is an aggressively managed fund while the indices are unmanaged, do
    not incur expenses and are not available for investment.

(2) Results of index performance are presented for general comparative purposes.

(3) Cumulative since inception total returns were 3,280.59%, 3,307.37% and
    3,451.48% for the Chestnut Street Exchange Fund, the S&P 500(R) Index and
    the Dow Jones Industrial Average Index, respectively for the period December
    29, 1976 (inception) to December 31, 2006.

                              FUND EXPENSE EXAMPLE
                                  (UNAUDITED)

     As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, and (2) ongoing costs, including management fees; and other Fund
expenses. The example is intended to help you understand your ongoing costs (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds.

     The example is based on an investment of $1,000 invested at the beginning
of the six-month period from July 1, 2006 through December 31, 2006, and held
for the entire period.

ACTUAL EXPENSES

     The first line of the accompanying table provides information about actual
account values and actual expenses. You may use the information in this line,
together with the amount you invested, to estimate the expenses that you paid
over the period. Simply divide your account value by $1,000 (for example, an
$8,600 account value divided by $1,000 = 8.6), then multiply the result by the
number in the first line under the heading entitled "Expenses Paid During
Period" to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

     The second line of the accompanying table provides information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not your Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and other funds. To do so, compare this
5% hypothetical example with the 5% hypothetical examples that appear in the
shareholder reports of other funds.

     Please note that the expenses shown in the accompanying table are meant to
highlight your ongoing costs only and do not reflect any transactional costs.
Therefore, the second line of the accompanying table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

* Expenses are equal to the Fund's annualized six-month expense ratio of 0.45%,
  multiplied by the average account value over the period, multiplied by the
  number of days (184) in the most recent fiscal half-year, then divided by 365
  to reflect the one-half year period. The Fund's ending account value on the
  first line of the table is based on the actual total return of 11.56% for the
  six month period ending December 31, 2006.

+ Hypothetical expenses are based on the Fund's actual annualized six-month
  expense ratio and an assumed rate of return of 5% per year before expenses.

                         NOTES TO FINANCIAL STATEMENTS

(A) ORGANIZATION

     Chestnut Street Exchange Fund (the "Fund"), a California Limited
     Partnership, is registered under the Investment Company Act of 1940, as
     amended, as a diversified open-end investment management company. The
     Fund's investment objective is to seek long-term growth of capital and,
     secondarily, current income. Effective January 1, 1998, the Fund changed
     its status for tax purposes from a partnership to a regulated investment
     company. The change resulted from the enactment of the "Publicly Traded
     Partnership" rules to the Internal Revenue Code in 1987, which first
     applied to the Fund after 1997.

(B) SIGNIFICANT ACCOUNTING PRINCIPLES

     The preparation of financial statements in conformity with accounting
     principles generally accepted in the United States of America requires
     management to make estimates and assumptions that affect the reported
     amounts of assets and liabilities at the date of the financial statements
     and the reported amounts of revenues and expenses during the reporting
     period. Actual results could differ from those estimates. The following is
     a summary of significant accounting policies followed by the Fund in the
     preparation of its financial statements.

          SECURITY VALUATIONS

        Securities listed or traded on an exchange are valued generally at the
        last sales price as of the close of the customary trading session on the
        exchange where the security is principally traded, or lacking any sales
        on a particular day, valued at the closing bid price on that day. Each
        security reported on the NASDAQ Stock Market, Inc. is valued at the
        NASDAQ Official Close Price. Securities for which market quotations are
        not readily available or are believed to be unreliable are valued at
        fair value as determined in good faith using methods approved by the
        Managing General Partners. Short-term obligations having 60 days or less
        to maturity are valued at amortized cost which approximates market
        value.

          SECURITIES TRANSACTIONS AND INVESTMENT INCOME

        Securities transactions are accounted for on a trade date basis.
        Realized gains and losses on sales and redemptions in kind are computed
        on the basis of specific identification for both financial reporting and
        income tax purposes. For securities exchanged into the Fund at the
        Fund's inception in 1976, the cost for financial reporting purposes is
        the value of those securities as used in the Exchange. The cost, for
        income tax purposes, of securities exchanged into the Fund is the tax
        basis of the individual investor. Interest income is recorded on the
        accrual basis. Dividend income is recorded on the ex-dividend date.

          DISTRIBUTIONS

        Distributions from net investment income are paid quarterly and recorded
        on the ex-dividend date. Distributions of capital gains, if any, are
        paid annually and recorded on the ex-dividend date.

                                        11


          FEDERAL INCOME TAXES

        The Fund intends to comply with the requirements of the Internal Revenue
        Code necessary to qualify as a regulated investment company and, as
        such, will not be subject to federal income taxes on otherwise taxable
        income which is distributed to shareholders. The Fund may elect not to
        distribute long-term capital gains to shareholders, but retain these
        gains and pay the income tax at the applicable corporate income tax
        rate. If the Fund elects to pay the tax on long-term capital gains, on
        the last day of the year the tax is paid, the partners are entitled to a
        proportionate credit for the tax payment and the tax basis of their
        shares is increased by the amount of undistributed gains less the tax
        paid by the Fund. At December 31, 2006, the Fund had a capital loss
        carryforward of $2,498,103, of which $2,276,902 expires December 31,
        2011 and $221,201 expires December 31, 2012. Therefore, no provision for
        federal income taxes is recorded in the financial statements.

(C) INVESTMENT ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES

     Prior to the Meeting of Partners on September 29, 2006, the Investment
     Advisers to the Fund were BlackRock Financial Management, Inc. and
     BlackRock Institutional Management Corporation ("BIMC") pursuant to an
     advisory agreement dated January 1, 1998, ("Prior Advisory Agreement"). At
     the September 29, 2006 meeting a new advisory agreement ("Advisory
     Agreement") providing for the same advisory, accounting and administrative
     services and the same fee as in the prior agreement was entered into with
     BlackRock Capital Management, Inc. ("BCM"), a wholly owned subsidiary of
     BIMC. All BlackRock entities named are subsidiaries of BlackRock, Inc. in
     which PNC Bank now holds a minority interest.

     The Advisory Agreement was necessitated by the uncertainty as to whether
     BlackRock's agreement with Merrill Lynch & Co. Inc. ("Merrill Lynch") by
     which Merrill Lynch contributed its investment management business to form
     a new asset management company, would constitute an assignment of the Prior
     Advisory Agreement under the Investment Company Act of 1940. If the
     transaction were determined to be such an assignment, it would have
     resulted in the automatic termination of the Prior Advisory Agreement.

     The Advisory Agreement provides for a fee at the annual rate of 4/10ths of
     1% of the first $100,000,000 of the Fund's average daily net assets plus
     3/10ths of 1% of net assets exceeding $100,000,000.

     PFPC Inc., an affiliate of PNC Bank, serves as the Fund's transfer and
     dividend disbursing agent. As compensation for these services, PFPC Inc. is
     entitled to a fee equal to $12,500 per year plus related out-of-pocket
     expense.

     PFPC Trust Company, a subsidiary of PFPC Inc, serves as the Fund's
     custodian. As compensation for its services as custodian, PFPC Trust
     Company is entitled to a fee computed at an annual rate of 0.0065% of the
     Fund's average gross assets plus additional fees based on the number and
     type of transactions.

     The managing general partners each receive a fixed fee as compensation for
     their services. In addition, the President, Treasurer and Chief Compliance
     Officer receives additional payments for overseeing the Fund's activities
     including compliance with federal securities laws, plus reimbursements of
     related expenses. Total payments to or for the managing general partners
     amounted to $90,264.

                                        12


     Legal fees amounting to $81,643 were paid to Drinker, Biddle & Reath LLP.
     Michael P. Malloy, Esq., Secretary of the Fund, is a partner of that firm.

(D) INVESTMENT TRANSACTIONS

     Purchases and sales of investment securities (excluding short-term
     obligations and redemptions in kind) were $2,756,754 and $2,760,903,
     respectively, for the year ended December 31, 2006.

(E) NET ASSETS

     At December 31, 2006, net assets consisted of:

<Table>
                                                                   
        Undistributed net investment income.........................  $      4,230
        Accumulated net realized loss on securities.................    (2,498,103)
        Net unrealized appreciation of investments (book basis).....   247,526,760
        Other capital -- paid-in or reinvested......................    45,547,547
                                                                      ------------
                                                                      $290,580,434
                                                                      ============
</Table>

(F) DISTRIBUTIONS TO SHAREHOLDERS

     Net investment income and capital gain distributions are determined in
     accordance with federal income tax regulations, which may differ from
     accounting principles generally accepted in the United States of America.
     The primary difference applicable to the Fund's distributions is the
     requirement to pass through 40% of its aggregate expenses to the partners
     of the Fund. This is required because the Fund has fewer than 500 partners
     and does not continuously offer shares. The partners treat this
     pass-through of expenses as a distribution of net investment income and a
     corresponding miscellaneous itemized deduction of investment expense.

     The tax character of distributions paid during 2006 and 2005 was as
     follows:

<Table>
<Caption>
                                                                         2006         2005
                                                                      ----------   ----------
                                                                             
        Ordinary income.............................................  $5,859,785   $5,548,000
        Investment expense..........................................    (491,616)    (478,141)
                                                                      ----------   ----------
                                                                      $5,368,169   $5,069,859
                                                                      ==========   ==========
</Table>

(G) IN-KIND DISTRIBUTION OF SECURITIES

     During the year ended December 31, 2006, the Fund distributed portfolio
     securities in lieu of cash for most shareholder redemptions. The value of
     these redemptions was as follows:

<Table>
<Caption>
                     NET REALIZED      FUND
     VALUE OF THE   GAIN INCLUDED     SHARES
     REDEMPTIONS    IN REDEMPTIONS   REDEEMED
     ------------   --------------   --------
                               
     $13,068,268     $11,490,446      37,201
</Table>

     Net realized gains from these transactions are not taxable to the Fund.
     Such gains are not distributed to shareholders and will be reclassified to
     paid-in capital at the Fund's fiscal year end. These transactions were
     completed following guidelines approved by the Managing General Partners.

                                        13


(H) INDEMNIFICATIONS

     In the ordinary course of business, the Fund enters into contracts that
     contain a variety of indemnifications. The Fund's maximum exposure under
     these arrangements is immaterial. The Fund has not had prior claims or
     losses pursuant to the contracts and expects the risk of loss to be remote.

(I) TAX MATTERS

    At December 31, 2006, the components of distributable earnings on a tax
    basis were as follows:

<Table>
                                                                   
        Undistributed ordinary income (before tax allocation
          described below)..........................................  $      4,230
        Capital loss carryover......................................    (2,498,103)
        Net unrealized appreciation of investments..................   251,867,376
                                                                      ------------
                                                                      $249,373,503
                                                                      ============
</Table>

    The cost of investments for federal income tax purposes at December 31, 2006
    was $40,312,766. The unrealized appreciation (an excess of value over cost)
    was $251,896,950 and the unrealized depreciation was $(29,574). The
    difference between book basis and tax basis of investments is attributable
    to the use of the individual partners' tax basis for those securities
    contributed to the Fund at its inception, as required by law.

    On December 31, 2006 undistributed net investment income was decreased by
    $1, undistributed net realized gain on securities was decreased by
    $11,428,300 and additional paid-in capital was increased by $11,428,301 due
    to permanent differing book and tax treatment of realized gains and losses.
    Net assets of the Fund were unaffected by this change.

(J) NEW ACCOUNTING PRONOUNCEMENTS

     On July 13, 2006 the Financial Accounting Standards Board ("FASB") released
     FASB Interpretation No. 48 "Accounting for the Uncertainty of Income Taxes"
     ("FIN 48"). FIN 48 provides guidance for how uncertain tax positions should
     be recognized, measured, presented and disclosed in the financial
     statements. FIN 48 requires the evaluation of tax positions taken or
     expected to be taken in the course of preparing the Fund's tax returns to
     determine whether the tax positions are "more-likely-than-not" of being
     sustained by the applicable tax authority. Tax positions not deemed to meet
     the more-likely-than-not threshold would be recorded as a tax benefit or
     expense in the current year and recognized as: a liability for unrecognized
     tax benefits; a reduction of an income tax refund receivable; a reduction
     of deferred tax asset; an increase in deferred tax liability; or a
     combination thereof. Funds are required to implement FIN 48 no later than
     its last NAV calculation in the first required financial statement
     reporting period for its fiscal year beginning after December 15, 2006.

     In September 2006, the FASB issued Statement on Financial Accounting
     Standards No. 157, "Fair Value Measurements" ("SFAS No. 157"). This
     standard establishes a single authoritative definition of fair value, sets
     out a framework for measuring fair value and requires additional
     disclosures about fair value measurements. SFAS No. 157 applies to fair
     value measurements already required or permitted by existing standards.
     SFAS No. 157 is effective for financial statements issued for fiscal years
     beginning after November 15, 2007 and interim periods within those fiscal
     years. The changes to current accounting principles generally accepted in
     the United States of America from the application of this Statement relate
     to the definition of fair value, the

                                        14


     methods used to measure fair value, and the expanded disclosures about fair
     value measurements. As of December 31, 2006, the Fund does not believe the
     adoption of SFAS No. 157 will impact the financial statement amounts;
     however, additional disclosures may be required about the inputs used to
     develop the measurements and the effect of certain of the measurements on
     changes in net assets for the period.

                                        15


            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Partners of
Chestnut Street Exchange Fund
Wilmington, Delaware

We have audited the accompanying statement of net assets of Chestnut Street
Exchange Fund (the "FUND"), as of December 31, 2006, and the related statement
of operations for the year then ended, the statement of changes in net assets
for each of the two years in the period then ended and the financial highlights
for the each of the four years in the period then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits. The financial
highlights for the year ended December 31, 2002 were audited by other auditors
whose report dated February 14, 2003 expressed an unqualified opinion on those
financial highlights.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of December 31, 2006 by correspondence with the custodian.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Chestnut Street Exchange Fund as of December 31, 2006, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended and the financial highlights for each of
the four years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

APPROVAL OF INVESTMENT ADVISORY CONTRACT

At a meeting held on July 13, 2006, the Board, including a majority of the
Managing General Partners who are not "interested persons" of the Fund (the
"Independent Managing Partners"), approved the Advisory Agreement with BlackRock
Capital Management, Inc. ("BCM") with respect to the Fund for

                                        17


an initial two-year period. In connection with their approval, the Managing
General Partners considered, with the assistance of independent counsel, their
legal responsibilities and reviewed the nature and quality of services provided
to the Fund and BCM's experience and qualifications.

Representatives of BlackRock, Inc. ("BlackRock") addressed and answered the
Board's questions about the Advisory Agreement. The BlackRock representatives
informed the Board that the combination of BlackRock and Merrill Lynch & Co.,
Inc. ("Merrill Lynch") will have no effect on the Fund, including the Fund's
portfolio management team. The Board reviewed materials relating to the Advisory
Agreement, including descriptions of the prior advisory agreement (see Note (C)
above) and the Advisory Agreement, a comparison of the Fund's advisory fees to
fees paid by similar investment companies, an overview of the investment
advisory and other services provided by BlackRock Institutional Management
Corporation ("BIMC") and BlackRock Financial Management, Inc. ("BFM") under the
prior advisory agreement and by BCM under the Advisory Agreement (including a
description of their equity portfolio capabilities and brokerage policies), a
review of the fees paid by the Fund to affiliates of PNC Bank, N.A. for
custodian services and transfer agency services, performance and expense data of
the Fund and comparable competitors and indices, and information concerning the
personnel rendering services to the Fund. The Board also discussed the
profitability of BIMC, BFM and BCM and reviewed a comparison of management fees
paid by other mutual funds. The Board discussed the various information provided
by BlackRock and reviewed the terms of the Advisory Agreement.

Among other items, the Board reviewed and considered: (1) a report comparing the
advisory fees and total expense ratio of shares of the Fund to those of its peer
group and to the peer group averages; (2) a report on the assets and advisory
fees for the Fund; (3) a report comparing the performance of the Fund to its
benchmarks, its peer group and the performance universe (e.g., all large cap
core equity funds) average; (4) a report on BCM's profitability related to
providing advisory services to the Fund after taking into account (i) advisory
fees and any other benefits realized by BCM or any of its affiliates as a result
of its role as service provider to the Fund, (ii) the direct and indirect
expenses incurred by BCM in providing investment advice to the Fund, and (iii)
other considerations; (5) possible economies of scale; (6) compensation or
possible benefits to BCM arising from its relationship with the Fund; and (7) a
report describing the resources, personnel, capabilities, overall nature and
quality of the services of BCM.

The Board also considered the commitment BCM has made to address new regulatory
compliance requirements applicable to the Fund and the adviser. Included in the
report provided by BCM for the Board's consideration were materials showing the
structure of BlackRock prior to and after the combination with Merrill Lynch.
BCM informed the Board that the services provided to the Fund by BCM under the
Advisory Agreement would be identical to those provided by BIMC and BFM under
the prior advisory agreement. BCM informed the Board that the individuals who
provided investment advisory services under the prior advisory agreement would
continue to provide such services under the Advisory Agreement.

The materials provided to the Board by BCM showed the corporate organization of
BlackRock, and specifically how BCM, BIMC and BFM fit into BlackRock's overall
corporate structure. The Board reviewed lists of portfolio managers for the
various BlackRock portfolio management platforms after the combination of
BlackRock and Merrill Lynch in order to determine that the Fund's portfolio
managers would remain the same after the combination. The Board further reviewed
the investment philosophies of the portfolio managers after the combination to
ensure that there would be no change in advisory services provided to the Fund.

                                        18


The Board considered the various reasons provided by BlackRock for combining
with Merrill Lynch, including (i) achieving economies of scale in their products
and markets; (ii) combining two strong, complementary businesses; (iii) having a
strong presence outside the United States; and (iv) becoming a more diversified
entity.

Representatives of BlackRock informed the Board that BlackRock's rationale
behind changing from BIMC and BFM as the Fund's investment adviser to BCM was to
improve BlackRock's organization after its combination with Merrill Lynch.
BlackRock informed the Board that BCM is a relatively new entity, which is
assigned for equity portfolios managed in its Boston and Philadelphia offices.
BlackRock further explained to the Board that there would be no change in
services provided to the Fund or to any of the individuals or teams responsible
for making investment decisions for the Fund as a result of the change in
investment adviser.

After discussion, the Board concluded that BCM had the capabilities, resources
and personnel necessary to manage the Fund. The Board also concluded that, based
on the services that BCM would provide to the Fund under the Advisory Agreement,
the fee was fair and equitable with respect to the Fund. The Board considered
the fees paid by the Fund in relation to its peer group, as well as the Fund's
performance. After evaluating the amounts paid by the Fund and the Fund's total
operating expenses compared to similar information for the Fund's peer group,
the Board concluded that the advisory fees paid by the Fund were reasonable.

The Board concluded that BCM had allocated sufficient resources and personnel to
the investment management operations of the Fund and was able to provide quality
services to the Fund. Based on the foregoing and upon such other information as
it considered necessary to the exercise of its reasonable business judgment, the
Board concluded unanimously that it was in the best interests of the Fund to
approve the Advisory Agreement with BCM for an initial two-year period.

         regardless of whether these individuals are employed by the registrant
         or a third party.

     (c) There have been no amendments, during the period covered by this
         report, to a provision of the code of ethics that applies to the
         registrant's principal executive officer, principal financial officer,
         principal accounting officer or controller, or persons performing
         similar functions, regardless of whether these individuals are employed
         by the registrant or a third party, and that relates to any element of
         the code of ethics description.

     (d) The registrant has not granted any waivers, including an implicit
         waiver, from a provision of the code of ethics that applies to the
         registrant's principal executive officer, principal financial officer,
         principal accounting officer or controller, or persons performing

         and regulatory filings or engagements for those fiscal years are

Audit-Related Fees

     (b) The aggregate fees billed in each of the last two fiscal years for
         assurance and related services by the principal accountant that are

                           (d) 0%

     (f) The percentage of hours expended on the principal accountant's
         engagement to audit the registrant's financial statements for the most
         recent fiscal year that were attributed to work performed by persons
         other than the principal accountant's full-time, permanent employees
         was 0%.

     (g) The aggregate non-audit fees billed by the registrant's accountant for
         services rendered to the registrant, and rendered to the registrant's
         investment adviser (not including any sub-adviser whose role is
         primarily portfolio management and is subcontracted with or overseen by
         another investment adviser), and any entity controlling, controlled by,
         or under common control with the adviser that provides ongoing services
         to the registrant for each of the last two fiscal years of the
