A Letter to Shareholders

Dear Shareholder

It has been a tumultuous period for investors, marked by almost daily headlines
of deepening turmoil in financial markets and a darkening economic outlook. The
news took an extraordinarily heavy tone late in the period as the credit crisis
boiled over and triggered unprecedented failures and consolidation in the
financial sector, stoking fears of a market and economic collapse and prompting
a series of new government programs designed to contain and combat the fallout.

The Federal Reserve Board (the "Fed") has taken decisive measures to restore
liquidity and stabilize the financial system. Key moves included slashing the
target federal funds rate 250 basis points (2.50%) between November 2007 and
April 2008 and providing massive cash injections and lending programs. In
October, as credit conditions further deteriorated, the central bank cut the key
interest rate by 50 basis points on two separate occasions -- on October 8 in
coordination with five other global central banks, and again during its
regularly scheduled meeting on October 29. This left the key short-term rate at
just 1.0%, its lowest level since 2004. While the U.S. economy appeared fairly
resilient through the second quarter of 2008, the third quarter saw a
contraction of 0.5%, and a more significant decline is expected for the fourth
quarter. Moreover, on December 1, the National Bureau of Economic Research
confirmed that the U.S. had entered a recession in December 2007.

Against this backdrop, U.S. equity markets experienced intense volatility, with
periods of downward pressure punctuated by sharp rebounds. Losses were
significant and broad-based, though small-cap stocks fared moderately better
than their larger counterparts. Non-U.S. markets decelerated at a considerably
faster pace than domestic equities -- a stark reversal of recent years' trends,
when international stocks generally outpaced U.S. stocks.

Treasury issues also traded in a volatile fashion, but rallied overall (yields
fell and prices correspondingly rose) and outperformed other fixed income assets
as investors continued their flight to higher quality and more liquid
securities. Tax-exempt issues generally underperformed, as problems among
municipal bond insurers and the collapse in the market for auction rate
securities afflicted the group throughout the course of the past year. At the
same time, the above mentioned economic headwinds and malfunctioning credit
markets plagued the high yield sector, with the third quarter of 2008 marking
one of the worst periods in history for the asset class.

Facing unprecedented volatility and macro pressures, the major benchmark indexes
generally recorded losses for the six- and 12-month reporting periods:

Fund Summary                             BlackRock Core Principal Protected Fund

Portfolio Management Commentary

      How did the Fund perform?

o     The Fund, through its investment in Master Large Cap Core Portfolio (the
      "Portfolio"), outperformed its all-equity benchmark, the Russell 1000
      Index for the twelve-month period ended October 31, 2008. At the beginning
      of the period, the Portfolio's equity allocation was at 100% of net assets
      and the fixed income allocation was at 0%. However, from July through the
      end of the period, market conditions dictated an increased allocation to
      fixed income, and therefore a reduced allocation to equity.

      What factors influenced performance?

o     The Fund's underperformance in consumer staples was almost entirely due to
      its underweight position, but stock selection in the sector was negative
      as well. We believe the underweight positioning is justified by the high
      valuations in that sector. Performance was also hurt by a combination of
      disappointing stock selection and an overweight in the information
      technology (IT) sector, especially among office electronics and
      semiconductors names. Finally, disappointing results from stock selection
      within health care, materials, energy and industrials offset the positive
      effects of allocation decisions among those sectors.

o     The consumer discretionary sector was a significant contributor to
      performance, as we focused on finding high-quality companies, companies
      with global revenue streams, turn-around companies, and companies that
      will benefit as consumers "trade down" (e.g., discounters such as Ross
      Stores, Inc.). The Portfolio's underweight in financials stocks (most
      notably in mortgage finance and capital markets companies) also helped
      performance.

o     The most significant individual contributors to Fund performance included
      AutoZone, Inc., Chubb Corp. and Express Scripts, Inc., as well as
      underweights in American International Group, Inc. and Citigroup, Inc. The
      biggest individual detractors from performance included Seagate
      Technology, Valero Energy Corp. and JPMorgan Chase & Co., as well as
      underweights in Wal-Mart Stores, Inc. and Wells Fargo & Co.

      Describe recent Portfolio activity.

o     During the period, we increased the Portfolio's exposure to the energy,
      IT, health care, industrials, consumer staples and consumer discretionary
      sectors. The Portfolio's largest purchases included Occidental Petroleum
      Corp., Cummins, Inc., Johnson & Johnson, Apache Corp. and Hess Corp.

o     We reduced Portfolio exposure to the materials and financials sectors. The
      Portfolio's largest sales included MetLife, Inc., Cisco Systems, Inc.,
      International Business Machines Corp., American International Group, Inc.
      and Medco Health Solutions, Inc.

      Describe Portfolio positioning at period-end.

o     On October 31, 2008, the Portfolio was overweight versus the benchmark in
      IT, health care, energy and consumer discretionary, and underweight in
      financials, consumer staples, utilities and telecommunication services.

o     We believe the U.S. economy is facing a deeper-than-normal recession that
      will put a significant drag on corporate earnings. Going forward, we still
      believe in the importance of high-quality U.S. multinationals, as many
      still have good earnings growth, quality balance sheets and good
      valuations. In this uncertain environment, quality is key. While the
      time-tested importance of fundamentals appears to have been absent from
      valuations recently, fundamentals do matter. When the market returns to a
      more "normal" state, we believe that owning high-quality companies will
      stand us in good stead.

report and are subject to change based on changes in market, economic or other
conditions. These views are not intended to be a forecast of future events and

1     For each class of the Fund, expenses are equal to the annualized expense
      ratio for the class (1.76% for Institutional, 1.93% for Investor A, 2.70%
      for Investor B and 2.70% for Investor C), multiplied by the average
      account value over the period, multiplied by 184/366 (to reflect the
      one-half year period shown). Because the Fund invests significantly in a
      master portfolio, the expense table example reflects the expenses of both
      the fund and the master portfolio in which it invests.
2     Hypothetical 5% annual return before expenses is calculated by pro-rating
      the number of days in the most recent fiscal half year divided by 366.

      See "Disclosure of Expenses" on page 6 for further information on how
      expenses were calculated.

the most recent month-end. Performance results do not reflect the deduction of
taxes that a shareholder would pay on fund distributions or the redemption of
fund shares. Performance data does not reflect this potential fee. Figures shown
in the performance tables on page 5 assume reinvestment of all dividends and
capital gain distributions, if any, at net asset value on the ex-dividend date.
Investment return and principal value of shares will fluctuate so that shares,
when redeemed, may be worth more or less than their original cost. Dividends
paid to each class of shares will vary because of the different levels of
service, distribution and transfer agency fees applicable to each class, which
are deducted from the income available to be paid to shareholders.

Disclosure of Expenses

Shareholders of this Fund may incur the following charges: (a) expenses related
to transactions, including sales charges, redemption fees and exchange fees; and
(b) operating expenses including advisory fees, distribution fees including
12b-1 fees, and other Fund expenses. The expense example on page 4 (which is
based on a hypothetical investment of $1,000 invested on May 1, 2008 and held
through October 31, 2008) is intended to assist shareholders both in calculating
expenses based on an investment in the Fund and in comparing these expenses with
similar costs of investing in other mutual funds.

The table provides information about actual account values and actual expenses.
In order to estimate the expenses a shareholder paid during the period covered
by this report, shareholders can divide their account value by $1,000 and then
multiply the result by the number corresponding to their share class under the
heading entitled "Expenses Paid During the Period."

The table also 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. In order to assist shareholders
in comparing the ongoing expenses of investing in this Fund and other funds,
compare the 5% hypothetical example with the 5% hypothetical examples that
appear in other funds' shareholder reports.

The expenses shown in the table are intended to highlight shareholders' ongoing
costs only and do not reflect any transactional expenses, such as sales charges,
redemption fees or exchange fees. Therefore, the hypothetical example is useful
in comparing ongoing expenses only, and will not help shareholders determine the
relative total expenses of owning different funds. If these transactional
expenses were included, shareholder expenses would have been higher.

  BLACKROCK CORE PRINCIPAL PROTECTED FUND              OCTOBER 31, 2008       11


Notes to Financial Statements            BlackRock Core Principal Protected Fund

1. Organization and Significant Accounting Policies:

BlackRock Core Principal Protected Fund (the "Fund") is a series of BlackRock
Principal Protected Trust ("the Trust") and is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as a diversified, open-end
management investment company. The Fund is organized as a Delaware statutory
trust. The Fund seeks to achieve its investment objective by investing all or a
portion of its assets in Master Large Cap Core Portfolio (the "Portfolio"),
which is a series of Master Large Cap Series LLC. The value of the Fund's
investment in the Portfolio reflects the Fund's proportionate interest in the
net assets of the Portfolio. The performance of the Fund is directly affected by
the performance of the Portfolio. The financial statements of the Portfolio,
including the Schedule of Investments, are included elsewhere in this report and
should be read in conjunction with the Fund's financial statements. The Fund's
financial statements are prepared in conformity with accounting principles
generally accepted in the United States of America, which may require the use of
management accruals and estimates. Actual results may differ from these
estimates. The percentage of the Portfolio owned by the Fund at October 31, 2008
was 0.6%. The Fund offers multiple classes of shares. Shares of the Fund were
offered during the initial offering period but will not be offered during the
Guarantee Period from February 28, 2003 through February 28, 2010 (the
"Guarantee Maturity Date"), except in connection with reinvestment of dividends
and distributions. The Fund will be offered on a continuous basis after the
Guarantee Maturity Date. Institutional Shares are sold without a sales charge
and only to certain eligible investors. Investor A Shares are generally sold
with a front-end sales charge. Investor B and Investor C Shares may be subject
to a contingent deferred sales charge. All classes of shares have identical
voting, dividend, liquidation and other rights and the same terms and
conditions, except that Investor A, Investor B and Investor C Shares bear
certain expenses related to the shareholder servicing of such shares, and
Investor B and Investor C Shares also bear certain expenses related to the
distribution of such shares. Each class has exclusive voting rights with respect
to matters relating to its shareholder servicing and distribution expenditures
(except that Investor B shareholders may vote on material changes to the
Investor A distribution plan).

The following is a summary of significant accounting policies followed by the
Fund:

Valuation of Investments: The Fund records its investment in the Portfolio at
fair value. Valuation of securities held by the Portfolio is discussed in Note 1
of the Portfolio's Notes to Financial Statements, which are included elsewhere
in this report.

The Fund values its bond investments on the basis of last available bid price or
current market quotations provided by dealers or pricing services selected under
the supervision of the Fund's Board of Trustees (the "Board"). In determining
the value of a particular investment, pricing services may use certain
information with respect to transactions in such investments, quotations from
dealers, pricing matrixes, market transactions in comparable investments,
various relationships observed in the market between investments, and calculated
yield measures based on valuation technology commonly employed in the market for
such investments.

In the event that application of these methods of valuation results in a price
for an investment which is deemed not to be representative of the market value
of such investment, the investment will be valued by a method approved by the
Board as reflecting fair value ("Fair Value Assets"). When determining the price
for Fair Value Assets, the investment advisor and/or sub-advisor seeks to
determine the price that the Fund might reasonably expect to receive from the
current sale of that asset in an arm's-length transaction. Fair value
determinations shall be based upon all available factors that the investment
advisor and/or subadvisor deems relevant. The pricing of all Fair Value Assets
is subsequently reported to the Board or a committee thereof.

Investment Transactions and Net Investment Income: Investment transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Income and realized and unrealized gains and losses are
allocated daily to each class based on its relative net assets.

Dividends and Distributions to Shareholders: Dividends and distributions paid by
the Fund are recorded on the ex-dividend dates.

Income Taxes: It is the Fund's policy to comply with the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no federal income tax provision is required.

Effective April 30, 2008, the Fund implemented Financial Accounting Standards
Board ("FASB") Interpretation No. 48, "Accounting for Uncertainty in Income
Taxes -- an interpretation of FASB Statement No. 109" ("FIN 48"). FIN 48
prescribes the minimum recognition threshold a tax position must meet in
connection with accounting for uncertainties in income tax positions taken or
expected to be taken by an entity, including investment companies, before being
measured and recognized in the financial statements. The investment advisor has
evaluated the application of FIN 48 to the Fund, and has determined that the
adoption of FIN 48 does not have a material impact on the Fund's financial
statements. The Fund files U.S. federal and various state and local tax returns.
No income tax returns are currently under examination. The statute of
limitations on the Fund's tax returns remains open for the years ended October
31, 2005 through October 31, 2007.The statutes of limitations on the Fund's
state and local tax returns may remain open for an additional year depending
upon the jurisdiction.

Notes to Financial Statements (continued)
                                         BlackRock Core Principal Protected Fund

Recent Accounting Pronouncements: In September 2006, Statement of Financial
Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"), was issued
and is effective for fiscal years beginning after November 15, 2007. FAS 157
defines fair value, establishes a framework for measuring fair value and expands
disclosures about fair value measurements. The impact on the Fund's financial
statement disclosures is currently being assessed.

In March 2008, Statement of Financial Accounting Standards No. 161, "Disclosures
about Derivative Instruments and Hedging Activities -- an amendment of FASB
Statement No. 133" ("FAS 161"), was issued. FAS 161 is intended to improve
financial reporting for derivative instruments by requiring enhanced disclosure
that enables investors to understand how and why an entity uses derivatives, how
derivatives are accounted for, and how derivative instruments affect an entity's
results of operations and financial position. In September 2008, FASB Staff
Position No. 133-1 and FASB Interpretation No. 45-4 (the "FSP"), "Disclosures
about Credit Derivatives and Certain Guarantees: An Amendment of FASB Statement
No. 133 and FASB Interpretation No. 45; and Clarification of the Effective Date
of FASB Statement No. 161," was issued and is effective for fiscal years and
interim periods ending after November 15, 2008. The FSP amends FASB Statement
No. 133 ("FAS 133"), "Accounting for Derivative Instruments and Hedging
Activities," to require disclosures by sellers of credit derivatives, including
credit derivatives embedded in hybrid instruments. The FSP also clarifies the
effective date of FAS 161, whereby disclosures required by FAS 161 are effective
for financial statements issued for fiscal years and interim periods beginning
after November 15, 2008. The impact on the Funds' financial statement
disclosures, if any, is currently being assessed.

Other: Expenses directly related to the Fund or its classes are charged to that
Fund or class. Other operating expenses shared by several funds are pro-rated
among those funds on the basis of relative net assets or other appropriate
methods. Other expenses of the Fund are allocated daily to each class based on
its relative net assets.

2. Investment Advisory Agreement and Other Transactions with Affiliates:

The Trust, on behalf of the Fund, has entered into an Investment Advisory
Agreement with BlackRock Advisors, LLC (the "Advisor"), an indirect, wholly
owned subsidiary of BlackRock, Inc., to provide investment advisory and
administrative services. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC
Financial Services Group, Inc. ("PNC") are principal owners of BlackRock, Inc.

The Advisor is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain other
services necessary to the operation of the Fund. For such services, the Fund
pays a monthly fee at an annual rate of 0.75% of the Fund's average daily net
assets.

The Advisor has contractually agreed to waive its advisory fee by the amount of
investment advisory fees the Fund pays the Advisor indirectly through its
investment in the Portfolio. For the year ended October 31, 2008, the Advisor
earned fees of $850,336, of which $493,109 was waived. This amount is shown on
the Statement of Operations as fees waived by the Advisor. In addition, the
Advisor has entered into a contractual arrangement with the Fund under which the
expenses incurred by each class of shares of the Fund (excluding distribution
and/or service fees) will not exceed 1.99%. This arrangement has a one-year term
and is renewable.

The Advisor has entered into a separate sub-advisory agreement with BlackRock
Investment Management, LLC ("BIM"), an affiliate of the Advisor, under which the
Advisor pays BIM, for services it provides, a monthly fee that is a percentage
of the investment advisory fee paid by the Fund to the Advisor.

For the year ended October 31, 2008, the Fund reimbursed the Advisor $1,995, for
certain accounting services, which is included in accounting services in the
Statement of Operations.

Effective October 1, 2008, the Fund has entered into separate Distribution
Agreements and Distribution Plans with BlackRock Investments, Inc. ("BII"),
which replaced FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc.
and its affiliates ("BDI") (collectively, the "Distributor") as the sole
distributor of the Fund. FAMD is a wholly owned subsidiary of Merrill Lynch
Group, Inc., and BII and BDI are affiliates of BlackRock, Inc. The service and
distribution fees did not change as a result of this transaction.

Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule
12b-1 under the 1940 Act, the Fund pays the Distributor ongoing service and
distribution fees. The fees are accrued daily and paid monthly at annual rates
based upon the average daily net assets of the shares as follows:

- --------------------------------------------------------------------------------
                                                        Service     Distribution
                                                          Fee           Fee
- --------------------------------------------------------------------------------
Investor A ........................................      0.25%           --
Investor B ........................................      0.25%         0.75%
Investor C ........................................      0.25%         0.75%
- --------------------------------------------------------------------------------

Pursuant to sub-agreements with each Distributor, broker-dealers, including
Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a wholly owned
subsidiary of Merrill Lynch, and the Distributor provide shareholder servicing
and distribution services to the Fund. The ongoing service and/or distribution
fee compensates the Distributor and each broker-dealer for providing shareholder
servicing and/or distribution related services to Investor A, Investor B and
Investor C shareholders.

Notes to Financial Statements (continued)
                                         BlackRock Core Principal Protected Fund

For the year ended October 31, 2008, the affiliates received contingent deferred
sales charges of $126,629 and $2,016 relating to transactions in Investor B and
Investor C Shares, respectively.

The Fund may earn income on positive cash balances in demand deposit accounts
that are maintained by the transfer agent on behalf of the Fund. For the year
ended October 31, 2008, the Fund earned $866, which is included in income from
affiliates in the Statement of Operations.

The Trust, on behalf of the Fund, and the Advisor have entered into a Financial
Guarantee Agreement with AMBAC Assurance Corporation ("AMBAC"). The Financial
Guarantee Agreement is intended to make sure that on the Guaranteed Maturity
Date, each shareholder of the Fund will be entitled to redeem his or her shares
for an amount no less than the initial value of that shareholder's account (less
expenses and sales charges not covered by the Financial Guarantee Agreement),
provided that all dividends and distributions received from the Fund have been
reinvested and no shares have been redeemed (the "Guaranteed Amount"). The Fund
will pay to AMBAC, under the Financial Guarantee Agreement, an annual fee equal
to 0.625% of the Fund's average daily net assets during the Guarantee Period. If
the value of the Fund's assets on the Guaranteed Maturity Date is insufficient
to result in the value of each shareholder's account being at least equal to the
shareholder's Guaranteed Amount, AMBAC will pay the Fund an amount sufficient to
make sure that each shareholder's account can be redeemed for an amount equal to
each shareholder's Guaranteed Amount.

Pursuant to written agreements, certain affiliates provide the Fund with
sub-accounting, recordkeeping, sub-transfer agency and other administrative
services with respect to sub-accounts they service. For these services, these
affiliates receive an annual fee per shareholder account which will vary
depending on share class. For the year ended October 31, 2008, the Fund paid
$81,042 in return for these services, which are a component of the transfer
agent fees in the accompanying Statement of Operations.

PNC Global Investment Servicing (U.S.) Inc., formerly PFPC Inc., an indirect,
wholly owned subsidiary of PNC and an affiliate of the Advisor, is the Fund's
transfer agent. Each class of the Fund bears the costs of transfer agent fees
associated with such respective classes. Transfer agency fees borne by each
class of the Fund are comprised of those fees charged for all shareholder
communications including mailing of shareholder reports, dividend and
distribution notices, and proxy materials for shareholders meetings, as well as
per account and per transaction fees related to servicing and maintenance of
shareholder accounts, including the issuing, redeeming and transferring of
shares of each class of the Fund, 12b-1 fee calculation, check writing,
anti-money laundering services, and customer identification services.

The Advisor maintains a call center, which is responsible for providing certain
shareholder services to the Fund, such as responding to shareholder inquiries
and processing transactions based upon instructions from shareholders with
respect to the subscription and redemption of Fund shares. During the year ended
October 31, 2008, the following amounts have been accrued by the Fund to
reimburse the Advisor for costs incurred running the call center, which are a
component of the transfer agent fees in the accompanying Statement of
Operations.

- --------------------------------------------------------------------------------
                                                                Call Center Fees
- --------------------------------------------------------------------------------
Institutional ...................................................    $   47
Investor A ......................................................    $  163
Investor B ......................................................    $1,260
Investor C ......................................................    $  805
- --------------------------------------------------------------------------------

Certain officers and/or trustees of the Trust are officers and/or trustees of
BlackRock, Inc. or its affiliates. The Fund reimburses the Advisor for
compensation paid to the Fund's Chief Compliance Officer.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the
year ended October 31, 2008 were $65,149,195 and $9,650,242, respectively.

4. Income Tax Information:

Reclassifications: Accounting principles generally accepted in the United States
of America require that certain components of net assets be adjusted to reflect
permanent differences between financial and tax reporting. The following
permanent differences as of October 31, 2008 attributable to net operating
losses were reclassified to the following accounts:

- -------------------------------------------------------------------------------
Decrease paid-in capital .......................................    $(1,558,331)
Increase undistributed net investment income ...................    $ 1,558,317
Increase accumulated net realized loss .........................    $        14
- -------------------------------------------------------------------------------

The tax character of distributions paid during the fiscal years ended October
31, 2008 and October 31, 2007 was as follows:

- --------------------------------------------------------------------------------
                                                        10/31/08       10/31/07
- --------------------------------------------------------------------------------
Distributions paid from:
  Ordinary income ................................    $ 3,342,850             --
  Long-term capital ..............................     23,187,166    $16,544,258
                                                      --------------------------
Total taxable distributions ......................    $26,530,016    $16,544,258
                                                      ==========================

As of October 31, 2008, the components of accumulated losses on a tax basis were
as follows:

- ------------------------------------------------------------------------------
Capital loss carryforward ....................................    $   (811,288)
Net unrealized losses ........................................     (10,403,649)*
                                                                  ------------
Total accumulated net losses .................................    $(11,214,937)
                                                                  ============

*     The difference between book-basis and tax-basis net unrealized losses is
      attributable primarily to the tax deferral of losses on wash sales and the
      timing of income recognition from partnership interests.

As of October 31, 2008, the Fund had a capital loss carryforward available to
offset future realized capital gains through the indicated expiration dates:

- --------------------------------------------------------------------------------
Expires October 31,
- --------------------------------------------------------------------------------
2016  ..............................................................    $811,288
                                                                        --------

  BLACKROCK CORE PRINCIPAL PROTECTED FUND              OCTOBER 31, 2008       15


Report of Independent Registered Public Accounting Firm
                                         BlackRock Core Principal Protected Fund

To the Shareholders and Board of Trustees of BlackRock Principal Protected
Trust:

We have audited the accompanying statement of assets and liabilities of
BlackRock Core Principal Protected Fund, one of the series constituting
BlackRock Principal Protected Trust (the "Trust") as of October 31, 2008, and
the related statement of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the five years in the period then ended.
These financial statements and financial highlights are the responsibility of
the Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

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. The Trust
is not required to have, nor were we engaged to perform an audit of its internal
control over financial reporting. Our audits included consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Trust's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. Our procedures included confirmation of the
securities owned as of October 31, 2008, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. 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
BlackRock Core Principal Protected Fund of BlackRock Principal Protected Trust
as of October 31, 2008, 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 five years in the period
then ended, in conformity with accounting principles generally accepted in the
United States of America.

                              ("BlackRock") in September 2006, the various legacy MLIM and legacy BlackRock Fund boards were
                              realigned and consolidated into three new Fund boards in 2007. As a result, although the chart shows
                              trustees as joining the Fund's board in 2007, each trustee first became a member of the board of
                              trustees of other legacy MLIM or legacy BlackRock Funds as follows: James H. Bodurtha since 1995;

Notes to Financial Statements                    Master Large Cap Core Portfolio

1. Organization and Significant Accounting Policies:

Master Large Cap Core Portfolio (the "Portfolio") is a series of Master Large
Cap Series LLC (the "Master LLC"). The Master LLC is registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), and is organized as
a Delaware limited liability company. The Limited Liability Company Agreement
permits the Board of Directors (the "Board") to issue non-transferable interests
in the Master LLC, subject to certain limitations. The Portfolio's financial
statements are prepared in conformity with accounting principles generally
accepted in the United States of America, which may require the use of
management accruals and estimates. Actual results may differ from these
estimates.

The following is a summary of significant accounting policies followed by the
Portfolio:

Valuation of Investments: Equity investments traded on a recognized securities
exchange or the NASDAQ Global Market System are valued at the last reported sale
price that day or the NASDAQ official closing price, if applicable. For equity
investments traded on more than one exchange, the last reported sale price on
the exchange where the stock is primarily traded is used. Equity investments
traded on a recognized exchange for which there were no sales on that day are
valued at the last available bid price. If no bid price is available, the prior
day's price will be used, unless it is determined that such prior day's price no
longer reflects the fair value of the security. The Portfolio values its
investments in the BlackRock Liquidity Series, LLC Money Market Series at fair
value, which is ordinarily based upon its pro-rata ownership in the net assets
of the underlying fund.

In the event that application of these methods of valuation results in a price
for an investment which is deemed not to be representative of the market value
of such investment, the investment will be valued by a method approved by the
Board as reflecting fair value ("Fair Value Assets"). When determining the price
for Fair Value Assets, the investment advisor and/or sub-advisor seeks to
determine the price that the Portfolio might reasonably expect to receive from
the current sale of that asset in an arm's-length transaction. Fair value
determinations shall be based upon all available factors that the investment
advisor and/or sub-advisor deems relevant. The pricing of all Fair Value Assets
is subsequently reported to the Board or a committee thereof.

Investment Transactions and Investment Income: Investment transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis.

Securities Lending: The Portfolio may lend securities to financial institutions
that provide cash or securities issued or guaranteed by the U.S. government as
collateral, which will be maintained at all times in an amount equal to at least
100% of the current market value of the loaned securities. The market value of
the loaned securities is determined at the close of business of the Portfolio
and any additional required collateral is delivered to the Portfolio on the next
business day. The Portfolio typically receives the income on the loaned
securities but does not receive the income on the collateral. Where the
Portfolio receives cash collateral, it may invest such collateral and retain the
amount earned on such investment, net of any amount rebated to the borrower. The
Portfolio may receive a flat fee for its loans. Loans of securities are
terminable at any time and the borrower, after notice, is required to return
borrowed securities within the standard time period for settlement of securities
transactions. The Portfolio may pay reasonable lending agent, administrative and
custodial fees in connection with its loans. In the event that the borrower
defaults on its obligation to return borrowed securities because of insolvency
or for any other reason, the Portfolio could experience delays and costs in
gaining access to the collateral. The Portfolio also could suffer a loss where
the value of the invested collateral falls below the market value of the
borrowed securities, either in the event of borrower default or in the event of
losses on investments made with cash collateral. For the year ended October 31,
2008, the Fund received only cash collateral for any securities loaned.

Income Taxes: The Portfolio is classified as a "pass-through entity" for federal
income tax purposes. As such, each investor in the Portfolio is treated as owner
of its proportionate share of the net assets, income, expenses and realized and
unrealized gains and losses of the Portfolio. Therefore, no federal income tax
provision is required.

It is intended that the Portfolio's assets will be managed so an investor in the
Portfolio can satisfy the requirements of Subchapter M of the Internal Revenue
Code. The Portfolio is disregarded as an entity separate from its owners for tax
purposes, therefore it is not required to file income tax returns.

Recent Accounting Pronouncements: In September 2006, Statement of Financial
Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"), was issued
and is effective for fiscal years beginning after November 15, 2007. FAS 157
defines fair value, establishes a framework for measuring fair value and expands
disclosures about fair value measurements. The impact on the Portfolio's
financial statement disclosures is currently being assessed.

In March 2008, Statement of Financial Accounting Standards No. 161, "Disclosures
about Derivative Instruments and Hedging Activities -- an amendment of FASB
Statement No. 133" ("FAS 161"), was issued. FAS 161 is intended to improve
financial reporting for derivative instruments by requiring enhanced disclosure
that enables investors to understand how and why an entity uses derivatives, how
derivatives are accounted for, and how derivative instruments affect an entity's
results of operations and financial position. In September 2008, FASB Staff
Position No. 133-1


  BLACKROCK CORE PRINCIPAL PROTECTED FUND              OCTOBER 31, 2008       27


Notes to Financial Statements (continued)        Master Large Cap Core Portfolio

and FASB Interpretation No. 45-4 (the "FSP"), "Disclosures about Credit
Derivatives and Certain Guarantees: An Amendment of FASB Statement No. 133 and
FASB Interpretation No. 45; and Clarification of the Effective Date of FASB
Statement No. 161," was issued and is effective for fiscal years and interim
periods ending after November 15, 2008. The FSP amends FASB Statement No. 133,
"Accounting for Derivative Instruments and Hedging Activities," to require
disclosures by sellers of credit derivatives, including credit derivatives
embedded in hybrid instruments. The FSP also clarifies the effective date of FAS
161, whereby disclosures required by FAS 161 are effective for financial
statements issued for fiscal years and interim periods beginning after November
15, 2008. The impact on the Portfolio's financial statement disclosures, if any,
is currently being assessed.

Bank Overdraft: The Portfolio recorded a bank overdraft, which resulted from
estimates of available cash.

Other: Expenses directly related to the Portfolio are charged to that Portfolio.
Other operating expenses shared by several funds are pro-rated among those funds
on the basis of relative net assets or other appropriate methods.

2. Investment Advisory Agreement and Other Transactions with Affiliates:

The Master LLC, on behalf of the Portfolio, entered into an Investment Advisory
Agreement with BlackRock Advisors, LLC (the "Advisor"), an indirect, wholly
owned subsidiary of BlackRock, Inc., to provide investment advisory and
administration services. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC
Financial Services Group, Inc. are principal owners of BlackRock, Inc.

The Advisor is responsible for the management of the Portfolio's investments and
provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Portfolio. For such services, the
Portfolio pays the Advisor a monthly fee at an annual rate of 0.50% of average
daily net assets not exceeding $1 billion, 0.45% of average daily net assets in
excess of $1 billion but not exceeding $5 billion and 0.40% of average daily net
assets in excess of $5 billion.

The Advisor has entered into a separate sub-advisory agreement with BlackRock
Investment Management, LLC ("BIM"), an affiliate of the Advisor with respect to
the Portfolio, under which the Advisor pays BIM for services it provides, a
monthly fee that is a percentage of the investment advisory fee paid by the
Portfolio to the Advisor.

For the year ended October 31, 2008, the Portfolio reimbursed the Advisor
$79,621 for certain accounting services, which are included in accounting
services in the Statement of Operations.

The Master LLC has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), a wholly owned subsidiary of Merrill
Lynch, or its affiliates. As of October 31, 2008, the Portfolio lent securities
with a value of $4,015,680 to MLPF&S or its affiliates. Pursuant to that order,
the Portfolio has retained BIM as the securities lending agent for a fee based
on a share of the returns on investment of cash collateral. BIM may, on behalf
of the Portfolio, invest cash collateral received by the Portfolio for such
loans, among other things, in a private investment company managed by the
Advisor or in registered money market funds advised by the Advisor or its
affiliates. For the year ended October 31, 2008, BIM received $608,113 in
securities lending agent fees.

Certain officers and/or directors of the Master LLC are officers and/or
directors of BlackRock, Inc. or its affiliates. The Portfolio reimburses the
Advisor for compensation paid to the Master LLC's Chief Compliance Officer.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the
year ended October 31, 2008 were $4,835,571,071 and $5,584,713,693,
respectively.

4. Short-Term Borrowings:

The Master LLC, on behalf of the Portfolio, along with certain other funds
managed by the Advisor and its affiliates, is party to a $500,000,000 credit
agreement with a group of lenders, which expired November 2008 and was
subsequently renewed until November 2009. The Portfolio may borrow under the
credit agreement to fund shareholder redemptions and for other lawful purposes
other than for leverage. The Portfolio may borrow up to the maximum amount
allowable under the Portfolio's current prospectus and statement of additional
information, subject to various other legal, regulatory or contractual limits.
The Portfolio pays a commitment fee of 0.06% per annum based on the Portfolio's
pro rata share of the unused portion of the credit agreement, which is included
in miscellaneous expenses in the Statement of Operations. Amounts borrowed under
the credit agreement bear interest at a rate equal to, at each fund's election,
the federal funds rate plus 0.35% or a base rate as defined in the credit
agreement. The Portfolio did not borrow under the credit agreement during the
year ended October 31, 2008.

5. Acquisitions:

On September 24, 2007, an investor of the Portfolio acquired all of the net
assets of BlackRock Investment Trust Portfolio of BlackRock Funds ("Investment
Trust"), pursuant to a plan of reorganization. As a result of the
reorganization, which included $286,539,853 of net unrealized appreciation, the
Portfolio received an in-kind contribution of portfolio securities.

6. Restatement:

During the current year's financial reporting process, the Portfolio determined
that the net unrealized appreciation recognized as a result of the

Notes to Financial Statements (concluded)        Master Large Cap Core Portfolio

September 24, 2007 reorganization described in Note 5 should have been reported
in the financial statements as proceeds received from contributions rather than
as part of the net change in unrealized appreciation for the year ended October
31, 2007. Accordingly, the Portfolio has restated its Statement of Changes in
Net Assets for the year ended October 31, 2007 to appropriately reduce the net
change in unrealized appreciation/depreciation and increase the proceeds from
contributions by a corresponding amount.

7. Subsequent Events:

On September 15, 2008, Bank of America Corporation announced that it has agreed
to acquire Merrill Lynch, one of the principal owners of BlackRock, Inc. The
purchase has been approved by the shareholders and directors of both companies
and certain regulators. Subject to other regulatory approvals, the transaction
is expected to close on or about December 31, 2008.

On November 14, 2008 (the "Reorganization Date"), an investor of the Portfolio
acquired all of the assets and certain stated liabilities of PNC Growth & Income
Fund (the "PNC Fund"), a series of PNC Funds, Inc. The reorganization was
pursuant to an Agreement and Plan of Reorganization, which was approved by the
shareholders of the PNC Fund on October 31, 2008. As a result of the
reorganization, which included $59,817,678 of net unrealized depreciation,
Master Large Cap Core received an in-kind contribution of portfolio securities.

Report of Independent Registered Public Accounting Firm
                                                 Master Large Cap Core Portfolio

To the Investors and Board of Directors of Master Large Cap Series LLC:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Master Large Cap Core Portfolio, one of the
portfolios constituting Master Large Cap Series LLC (the "Master LLC"), as of
October 31, 2008, the related statement of operations for the year then ended,
the statements of changes in net assets for each of the two years in the period
then ended and the financial highlights for each of the five years in the period
then ended. These financial statements and financial highlights are the
responsibility of the Master LLC's management. Our responsibility is to express
an opinion on these financial statements and financial highlights based on our
audits.

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. The
Master LLC is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audits included consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Master LLC's internal control
over financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2008, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. 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 Master
Large Cap Core Portfolio of Master Large Cap Series LLC as of October 31, 2008,
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 its financial
highlights for each of the five years in the period then ended, in conformity
with accounting principles generally accepted in the United States of America.

As discussed in Note 6, the Statement of Changes in Net Assets of Master Large
Cap Core Portfolio for the year ended October 31, 2007, has been restated.

                        2     Following the combination of Merrill Lynch Investment Managers, L.P. ("MLIM") and BlackRock, Inc.
                              ("BlackRock") in September 2006, the various legacy MLIM and legacy BlackRock Fund boards were
                              realigned and consolidated into three new Fund boards in 2007. As a result, although the chart shows
                              certain directors as joining the Master LLC's board in 2007, each director first became a member of
                              the board of directors of other legacy MLIM or legacy BlackRock Funds as follows: David O. Beim since
                              1998; Ronald W. Forbes since 1977; Matina Horner since 2004; Rodney D. Johnson since 1995; Herbert I.

32       BLACKROCK CORE PRINCIPAL PROTECTED FUND              OCTOBER 31, 2008


Disclosure of Investment Advisory Agreement and Subadvisory Agreement

The Board of Trustees (the "Board," the members of which are referred to as
"Trustees") of BlackRock Core Principal Protected Fund (the "Fund"), a series of
BlackRock Principal Protected Trust (the "Trust") met in April and June 2008 to
consider the approval of the Trust's investment advisory agreement (the
"Advisory Agreement") with BlackRock Advisors, LLC (the "Advisor"), the Trust's
investment advisor. The Board also considered the approval of the subadvisory
agreement (the "Subadvisory Agreement") between the Advisor and BlackRock
Investment Management, LLC (the "Subadvisor"). For simplicity, the Fund and the
Trust are referred to herein as the "Fund." The Advisor and the Subadvisor are
referred to herein as "BlackRock." The Advisory Agreement and the Subadvisory
Agreement are referred to herein as the "Agreements."

Activities and Composition of the Board

The Board of the Fund consists of fifteen individuals, twelve of whom are not
"interested persons" of the Fund as defined in the Investment Company Act of
1940, as amended (the "1940 Act") (the "Independent Trustees"). The Trustees are
responsible for the oversight of the operations of the Fund and perform the
various duties imposed on the directors of investment companies by the 1940 Act.
The Independent Trustees have retained independent legal counsel to assist them
in connection with their duties. The Chairman of the Board is an Independent
Trustee. The Board established four standing committees: an Audit Committee, a
Governance and Nominating Committee, a Compliance Committee and a Performance
Oversight Committee, each of which is composed of, and chaired by Independent
Trustees.

The Agreements

Upon the consummation of the combination of BlackRock's investment management
business with Merrill Lynch & Co., Inc.'s investment management business,
including Merrill Lynch Investment Managers, L.P., and certain affiliates (the
"Transaction"), the Fund entered into the Advisory Agreement with an initial
two-year term and the Advisor entered into the Subadvisory Agreement with the
Subadvisor with an initial two-year term. Consistent with the 1940 Act, prior to
the expiration of the Agreements' respective initial two-year term, the Board is
required to consider the continuation of the Fund's Agreements on an annual
basis. In connection with this process, the Board assessed, among other things,
the nature, scope and quality of the services provided to the Fund by the
personnel of BlackRock and its affiliates, including investment management,
administrative services, shareholder services, oversight of fund accounting and
custody, marketing services and assistance in meeting legal and regulatory
requirements.

Throughout the year, the Board, acting directly and through its committees,
considers at each of its meetings factors that are relevant to its annual
consideration of the renewal of the Fund's Agreements, including the services
and support provided to the Fund and its shareholders. Among the matters the
Board considered were: (a) investment performance for one, three and five years,
as applicable, against peer funds, as well as senior management and portfolio
managers' analysis of the reasons for underperformance, if applicable; (b) fees,
including advisory, administration, if applicable, and other fees paid to
BlackRock and its affiliates by the Fund, such as transfer agency fees and fees
for marketing and distribution; (c) Fund operating expenses; (d) the resources
devoted to and compliance reports relating to the Fund's investment objective,
policies and restrictions; (e) the Fund's compliance with its Code of Ethics and
compliance policies and procedures; (f) the nature, cost and character of
non-investment management services provided by BlackRock and its affiliates; (g)
BlackRock's and other service providers' internal controls; (h) BlackRock's
implementation of the proxy voting guidelines approved by the Board; (i) the use
of brokerage commissions and spread and execution quality; (j) valuation and
liquidity procedures; and (k) periodic overview of BlackRock's business,
including BlackRock's response to the increasing scale of its business.

Board Considerations in Approving the Agreements

The Approval Process: At an in-person meeting held on April 10, 2008, the Board
reviewed materials relating to its consideration of the Agreements. At an
in-person meeting held on June 5 - 6, 2008, the Fund's Board, including the
Independent Trustees, unanimously approved the continuation of the Advisory
Agreement between the Advisor and the Fund for a one-year term ending June 30,
2009 and the Subadvisory Agreement between the Advisor and BlackRock Investment
Management, LLC for a one-year term ending June 30, 2009. In considering the
approval of the Agreements, the Board received and discussed various materials
provided to it in advance of the April 10, 2008 meeting. As a result of the
discussions that occurred during the April 10, 2008 meeting, the Board requested
and BlackRock provided additional information, as detailed below, in advance of
the June 5 - 6, 2008 Board meeting. The Board considered all factors it believed
relevant with respect to the Fund, including, among other factors: (a) the
nature, extent and quality of the services provided by BlackRock; (b) the
investment performance of the Fund and BlackRock portfolio management; (c) the
advisory fee and the cost of the services and profits to be realized by
BlackRock and certain affiliates from the relationship with the Fund; (d)
economies of scale; and (e) other factors.


  BLACKROCK CORE PRINCIPAL PROTECTED FUND              OCTOBER 31, 2008       33


Disclosure of Investment Advisory Agreement and Subadvisory Agreement
(continued)

Prior to the April 10, 2008 meeting, the Board requested and received materials
specifically relating to the Agreements. The Board is engaged in an ongoing
process with BlackRock to continuously review the nature and scope of the
information provided to better assist its deliberations. These materials
included (a) information independently compiled and prepared by Lipper, Inc.
("Lipper") on Fund fees and expenses, and the investment performance of the Fund
as compared with a peer group of funds as determined by Lipper ("Peers"); (b)
information on the profitability of the Agreements to BlackRock and certain
affiliates, including their other relationships with the Fund, and a discussion
of fall-out benefits; (c) a general analysis provided by BlackRock concerning
investment advisory fees charged to other clients, such as institutional and
closed-end funds, under similar investment mandates, as well as the performance
of such other clients; (d) a report on economies of scale; (e) sales and
redemption data regarding the Fund's shares; and (f) an internal comparison of
management fees classified by Lipper, if applicable. At the April 10, 2008
meeting, the Board requested and subsequently received from BlackRock (i) a
comprehensive analysis of total expenses on a fund-by-fund basis; (ii) further
analysis of investment performance; (iii) further data regarding Fund
profitability, Fund size and Fund fee levels; and (iv) additional information on
sales and redemptions.

The Board also considered other matters it deemed important to the approval
process, such as payments made to BlackRock or its affiliates relating to the
distribution of Fund shares, services related to the valuation and pricing of
Fund portfolio holdings, and direct and indirect benefits to BlackRock and its
affiliates from their relationship with the Fund. The Board did not identify any
particular information as controlling, and each Trustee may have attributed
different weights to the various items considered.

A. Nature, Extent and Quality of the Services: The Board, including the
Independent Trustees, reviewed the nature, extent and quality of services
provided by BlackRock, including the investment advisory services and the
resulting performance of the Fund. Throughout the year, the Board compared Fund
performance to the performance of a comparable group of mutual funds as
classified by Lipper and the performance of at least one relevant index or
combination of indices. The Board met with BlackRock's senior management
personnel responsible for investment operations, including the senior investment
officers. The Board also reviewed the materials provided by the Fund's portfolio
management team discussing Fund performance and the Fund's investment objective,
strategies and outlook.

The Board considered, among other factors, the number, education and experience
of BlackRock's investment personnel generally and the Fund's portfolio
management team, BlackRock's portfolio trading capabilities, BlackRock's use of
technology, BlackRock's commitment to compliance and BlackRock's approach to
training and retaining portfolio managers and other research, advisory and
management personnel. The Board also reviewed BlackRock's compensation structure
with respect to the Fund's portfolio management team and BlackRock's ability to
attract and retain high-quality talent.

In addition to advisory services, the Board considered the quality of the
administrative and non-investment advisory services provided to the Fund.
BlackRock and its affiliates provide the Fund with certain administrative,
transfer agency, shareholder and other services (in addition to any such
services provided to the Fund by third parties) and officers and other personnel
as are necessary for the operations of the Fund. In addition to investment
advisory services, BlackRock and its affiliates provide the Fund with other
services, including (i) preparing disclosure documents, such as the prospectus,
the statement of additional information and shareholder reports; (ii) assisting
with daily accounting and pricing; (iii) overseeing and coordinating the
activities of other service providers; (iv) organizing Board meetings and
preparing the materials for such Board meetings; (v) providing legal and
compliance support; and (vi) performing other administrative functions necessary
for the operation of the Fund, such as tax reporting and fulfilling regulatory
filing requirements. The Board reviewed the structure and duties of BlackRock's
fund administration, accounting, legal and compliance departments.

B. The Investment Performance of the Fund and BlackRock: The Board, including
the Independent Trustees, also reviewed and considered the performance history
of the Fund. In preparation for the April 10, 2008 meeting, the Board was
provided with reports, independently prepared by Lipper, which included a
comprehensive analysis of the Fund's performance. The Board also reviewed a
narrative and statistical analysis of the Lipper data that was prepared by
BlackRock, which analyzed various factors that affect Lipper's rankings. In
connection with its review, the Board received and reviewed information
regarding the investment performance of the Fund as compared to a representative
group of similar funds as determined by Lipper and to all funds in the Fund's
applicable Lipper category. The Board was provided with a description of the
methodology used by Lipper to select peer funds. The Board regularly reviews the
performance of the Fund throughout the year. The Board attaches more importance
to performance over relatively long periods of time, typically three to five
years.


34       BLACKROCK CORE PRINCIPAL PROTECTED FUND              OCTOBER 31, 2008


Disclosure of Investment Advisory Agreement and Subadvisory Agreement
(continued)

The Fund ranked in the third, third and fourth quartiles on a net basis against
its Lipper peer universe for the one-year and three-year periods and since
inception ended December 31, 2007, respectively. The Board expressed its concern
with the Fund's investment performance. The Board will continue its ongoing
dialogue with BlackRock on the Fund's performance.

C. Consideration of the Advisory Fees and the Cost of the Services and Profits
to be Realized by BlackRock and its Affiliates from the Relationship with the
Fund: The Board, including the Independent Trustees, reviewed the Fund's
contractual advisory fee rates compared with the other funds in its Lipper
category. It also compared the Fund's total expenses to those of other
comparable funds. The Board considered the services provided and the fees
charged by BlackRock to other types of clients with similar investment mandates,
including separately managed institutional accounts.

The Board received and reviewed statements relating to BlackRock's financial
condition and profitability with respect to the services it provided the Fund.
The Board was also provided with a profitability analysis that detailed the
revenues earned and the expenses incurred by BlackRock and certain affiliates
that provide services to the Fund. The Board reviewed BlackRock's profitability
with respect to the Fund and each fund the Board currently oversees for the year
ended December 31, 2007 compared to aggregated profitability data provided for
the year ended December 31, 2005.

In addition, the Board considered the cost of the services provided to the Fund
by BlackRock, and BlackRock's and its affiliates' profits relating to the
management and distribution of the Fund and the other funds advised by BlackRock
and its affiliates. As part of its analysis, the Board reviewed BlackRock's
methodology in allocating its costs to the management of the Fund and concluded
that there was a reasonable basis for the allocation. The Board also considered
whether BlackRock has the financial resources necessary to attract and retain
high quality investment management personnel to perform its obligations under
the Agreements and to continue to provide the high quality of services that are
expected by the Board.

The Board noted that, although the Fund has contractual advisory fees higher
than its Peers because Lipper includes the contractual advisory fees of Master
Large Cap Core Portfolio (the "Master Portfolio"), a series of Master Large Cap
Series LLC, in which the Fund invests a portion of its assets. Taking into
account the contractual waiver of the advisory fee by the amount of advisory
fees the Fund pays BlackRock indirectly through its investment in the Master
Portfolio, the Fund's contractual advisory fee would be comparable to fees paid
by its Peers. The Board noted that BlackRock has agreed to contractually cap the
total annual operating expenses, excluding certain expenses, of one or more
share classes of the Fund, at certain levels. The Board observed that those
expense caps benefited shareholders by keeping total fees down even in the
absence of breakpoints.

D. Economies of Scale: The Board, including the Independent Trustees, considered
the extent to which economies of scale might be realized as the assets of the
Fund increase and whether there should be changes in the advisory fee rate or
structure in order to enable the Fund to participate in these economies of
scale. The Board, including the Independent Trustees, considered whether the
shareholders would benefit from economies of scale and whether there was
potential for future realization of economies with respect to the Fund. The
Board considered that the funds in the BlackRock fund complex share common
resources and, as a result, an increase in the overall size of the complex could
permit each fund to incur lower expenses than it would otherwise as stand-alone
entities. The Board also considered the anticipated efficiencies in the
processes of BlackRock's overall operations as it continues to add personnel and
commit capital to expand the scale of operations. The Board found, based on its
review of comparable funds, that the Fund's management fee is appropriate in
light of the scale of the Fund.

E. Other Factors: The Board also took into account other ancillary or "fall-out"
benefits that BlackRock may derive from its relationship with the Fund, both
tangible and intangible, such as BlackRock's ability to leverage its investment
professionals that manage other portfolios, an increase in BlackRock's profile
in the investment advisory community, and the engagement of BlackRock's
affiliates as service providers to the Fund, including for administrative,
transfer agency and distribution services. The Board also noted that BlackRock
may use third-party research obtained by soft dollars generated by transactions
in the Fund to assist itself in managing all or a number of its other client
accounts.


  BLACKROCK CORE PRINCIPAL PROTECTED FUND              OCTOBER 31, 2008       35


Disclosure of Investment Advisory Agreement and Subadvisory Agreement
(concluded)

In connection with its consideration of the Agreements, the Board also received
information regarding BlackRock's brokerage and soft dollar practices. The Board
received reports from BlackRock which included information on brokerage
commissions and trade execution practices throughout the year.

Conclusion

The Board approved the continuation of the Advisory Agreement between the
Advisor and the Fund for a one-year term ending June 30, 2009 and the
Subadvisory Agreement between the Advisor and BlackRock Investment Management,
LLC for a one-year term ending June 30, 2009. Based upon its evaluation of all
these factors in their totality, the Board, including the Independent Trustees,
was satisfied that the terms of the Agreements were fair and reasonable and in
the best interest of the Fund and the Fund's shareholders. In arriving at a
decision to approve the Agreements, the Board did not identify any single factor
or group of factors as all-important or controlling, but considered all factors
together. The Independent Trustees were also assisted by the advice of
independent legal counsel in making this determination. The contractual fee
arrangements for the Fund reflect the result of several years of review by the
Trustees and predecessor Trustees, and discussions between the Trustees (and
predecessor Trustees) and BlackRock. Certain aspects of the arrangements may be
the subject of more attention in some years than in others, and the Trustees'
conclusions may be based in part on their consideration of these arrangements in
prior years.

            Under applicable securities laws, a person determined to be an audit
            committee financial expert will not be deemed an "expert" for any
            purpose, including without limitation for the purposes of Section 11
            of the Securities Act of 1933, as a result of being designated or
            identified as an audit committee financial expert. The designation
            or identification as an audit committee financial expert does not
            impose on such person any duties, obligations, or liabilities
            greater than the duties, obligations, and liabilities imposed on
            such person as a member of the audit committee and board of
            directors in the absence of such designation or identification.

1     The nature of the services include assurance and related services
      reasonably related to the performance of the audit of financial statements
      not included in Audit Fees.
2     The nature of the services include tax compliance, tax advice and tax
      planning.
3     The nature of the services include a review of compliance procedures and
      attestation thereto.

            (e)(1) Audit Committee Pre-Approval Policies and Procedures:

                  The registrant's audit committee (the "Committee") has adopted
            policies and procedures with regard to the pre-approval of services.
            Audit, audit-related and tax compliance services provided to the
            registrant on an annual basis require specific pre-approval by the
            Committee. The Committee also must approve other non-audit services
            provided to the registrant and those non-audit services provided to
            the registrant's affiliated service providers that relate directly
            to the operations and the financial reporting of the registrant.
            Certain of these non-audit services that the Committee believes are
            a) consistent with the SEC's auditor independence rules and b)
            routine and recurring services that will not impair the independence
            of the independent accountants may be approved by the Committee
            without consideration on a specific case-by-case basis ("general
            pre-approval"). The term of any general pre-approval is 12 months
            from the date of the pre-approval, unless the Committee provides for
            a different period. Tax or other non-audit services provided to the
            registrant which have a direct impact on the operation or financial
            reporting of the registrant will only be deemed pre-approved



            provided that any individual project does not exceed $10,000
            attributable to the registrant or $50,000 for all of the registrants
            the Committee oversees. For this purpose, multiple projects will be
            aggregated to determine if they exceed the previously mentioned cost
            levels.

                  Any proposed services exceeding the pre-approved cost levels
            will require specific pre-approval by the Committee, as will any
            other services not subject to general pre-approval (e.g.,
            unanticipated but permissible services). The Committee is informed
            of each service approved subject to general pre-approval at the next
            regularly scheduled in-person board meeting. At this meeting, an
            analysis of such services is presented to the Committee for
            ratification. The Committee may delegate to one or more of its
            members the authority to approve the provision of and fees for any
            specific engagement of permitted non-audit services, including
            services exceeding pre-approved cost levels.

            (e)(2) None of the services described in each of Items 4(b) through
            (d) were approved by the audit committee pursuant to paragraph
            (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

            (h) The registrant's audit committee has considered and determined
            that the provision of non-audit services that were rendered to the
            registrant's investment adviser (not including any non-affiliated
            sub-adviser whose role is primarily portfolio management and is
            subcontracted with or overseen by the registrant's investment
            adviser), and any entity controlling, controlled by, or under common
            control with the investment adviser that provides ongoing services
            to the registrant that were not pre-approved pursuant to paragraph
            (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with
            maintaining the principal accountant's independence.

            nominee should send nominations that include biographical
            information and set forth the qualifications of the proposed nominee
            to the registrant's Secretary. There have been no material changes
            to these procedures.
