The Benefits and Risks of Leveraging

BlackRock Corporate High Yield Fund III, Inc. utilizes leveraging through
borrowings or issuance of short-term debt securities or shares of Preferred
Stock. The concept of leveraging is based on the premise that the cost of assets
to be obtained from leverage will be based on short-term interest rates, which
normally will be lower than the income earned by the Fund on its longer-term
portfolio investments. Since the total assets of the Fund (including the assets
obtained from leverage) are invested in higher-yielding portfolio investments,
the Fund's Common Stock shareholders are the beneficiaries of the incremental
yield.

Leverage creates risks for holders of Common Stock including the likelihood of
greater net asset value and market price volatility. In addition, there is the
risk that fluctuations in interest rates on borrowings (or in the dividend rates
on any Preferred Stock, if the Fund were to issue Preferred Stock) may reduce
the Common Stock's yield and negatively impact its net asset value and market
price. If the income derived from securities purchased with assets received from
leverage exceeds the cost of leverage, the Fund's net income will be greater
than if leverage had not been used. Conversely, if the income from the
securities purchased is not sufficient to cover the cost of leverage, the Fund's
net income will be less than if leverage had not been used, and therefore the
amount available for distribution to Common Stock shareholders will be reduced.

A Letter to Shareholders

Dear Shareholder

As 2006 nears a conclusion, we are able to say it has been an interesting year
for investors. After a volatile start and far-reaching mid-year correction, the
financial markets regained some positive momentum through late summer and into
fall. For the six-month and 12-month periods ended November 30, 2006, the major
market indexes posted positive returns:

After raising the target short-term interest rate 17 times between June 2004 and
June 2006, the Federal Reserve Board (the Fed) finally opted to pause on August
8. This left the federal funds rate at 5.25%, where it remained through the
September, October and December Federal Open Market Committee meetings. In
interrupting its two-year interest rate-hiking campaign, the Fed acknowledged
that economic growth is slowing, led by softness in the housing market. However,
the central bankers continue to take a cautionary position on inflation, despite
a decline in energy prices in the fall. At the time of this writing, the price
of crude oil was roughly $62 per barrel after reaching nearly $78 per barrel in
the summer.

Notwithstanding the mid-year correction, equity markets generally found support
in solid corporate earnings reports in the first three quarters of the year.
Overall corporate health, including strong company balance sheets, helped to
sustain robust dividend-distribution, share-buyback and merger-and-acquisition
activity. Many international equity markets fared equally well or better, thanks
in part to higher economic growth rates and low inflation.

In the U.S. bond market, prices declined (and yields correspondingly rose) for
much of the year as investors focused on decent economic activity and inflation
concerns. Bond prices began to improve (yields fell) in the summer as the
economy showed signs of weakening and the Fed paused. Notably, the Treasury
curve inverted periodically, a phenomenon typically associated with periods of
economic weakness. At the end of November, the one-month Treasury bill offered
the highest yield on the curve at 5.22%, while the 30-year Treasury bond had a
yield of 4.56%.

Amid the uncertainty inherent in the financial markets, we encourage you to
review your goals periodically with your financial professional and to make
portfolio changes, as needed. For additional insight and timely "food for
thought" for investors, we also invite you to visit Shareholder magazine at
www.blackrock.com/shareholdermagazine. We are pleased to make our
investor-friendly magazine available to you online. We thank you for trusting
BlackRock with your investment assets, and we look forward to continuing to

A Discussion With Your Fund's Portfolio Managers

      The Fund performed in line with its benchmark for the six-month period,
benefiting primarily from the strong returns of its holdings in convertible
securities.

How did the Fund perform during the period in light of the existing market
conditions?

For the six-month period ended November 30, 2006, the Common Stock of BlackRock
Corporate High Yield Fund III, Inc. (formerly Corporate High Yield Fund III,
Inc.) had net annualized yields of 9.08% and 9.79%, based on a period-end per
share net asset value of $8.61 and a per share market price of $7.99,
respectively, and $.392 per share income dividends. For the same period, the
total investment return on the Fund's Common Stock was +6.29%, based on a change
in per share net asset value from $8.46 to $8.61, and assuming reinvestment of
all distributions. The high yield bond market, as measured by the Credit Suisse
High Yield Index, returned +6.28% for the six-month period, while the Fund's
comparable Lipper category of High Current Yield Funds (Leveraged) had an
average return of +6.61%. (Funds in this Lipper category aim for relatively high
current yield from investment in fixed income securities, have no quality or
maturity restrictions, and tend to invest in lower-grade debt issues.)

For a description of the Fund's total investment return based on a change in the
per share market value of the Fund's Common Stock (as measured by the trading
price of the Fund's shares on the New York Stock Exchange), and assuming
reinvestment of dividends, please refer to the Financial Highlights section of
this report. As a closed-end fund, the Fund's shares may trade in the secondary
market at a premium or a discount to the Fund's net asset value. As a result,
total investment returns based on changes in the market value of the Fund's
Common Stock can vary significantly from total investment returns based on
changes in the Fund's net asset value.

The Federal Reserve Board (the Fed) raised the target federal funds rate in two
increments of .25% during the six-month period, bringing the target rate from
4.75% to 5.25%. However, the Fed held the rate steady at its meetings on August
8, September 20 and October 25, 2006. The third quarter of 2006 was the first
without an increase in the federal funds target rate since the first quarter of
2004.

In the statement following its October 25 meeting, the Federal Open Market
Committee (FOMC) wrote: "Economic growth has slowed over the course of the year,
partly reflecting a cooling of the housing market. Going forward, the economy
seems likely to expand at a moderate pace." In a cautionary tone, however, the
FOMC indicated that "the Committee judges that some inflation risks remain. The
extent and timing of any additional firming that may be needed to address these
risks will depend on the evolution of the outlook for both inflation and
economic growth, as implied by incoming information."

As measured by the Credit Suisse High Yield Index, the yield spreads of high
yield bonds versus 10-year U.S. Treasury securities increased from 329 basis
points (3.29%) on May 31, 2006, to 350 basis points at the end of the period on
November 30, 2006.

What factors most influenced Fund performance?

The continued strength of the high yield market helped propel Fund results over
the past six months. Our holdings in convertible securities benefited
performance relative to the benchmark, reflecting both favorable corporate
earnings announcements and a stronger equity market. Conversely, the portfolio's
relatively conservative positioning hindered performance somewhat, as
lower-quality, longer-duration securities outperformed the broad market during
the semi-annual period.

What changes were made to the portfolio during the period?

We continued to shift assets from CCC-rated securities into more defensive,
higher-rated issues. We have focused on B-rated issues, with only a modest
weighting in riskier CCC-rated securities. From a sector perspective, our
emphasis shifted from overweight positions versus the Credit Suisse High Yield
Index in health care and media -- cable to overweights in media -- non-cable,
gaming and paper. We maintained the portfolio's underweight positions in the
utilities and cable sectors.

During the period, declining interest rates resulted in lower borrowing costs
for the Fund. The decreasing cost of leverage had a positive effect on the
Fund's earnings during the period. While leveraging will enhance the Fund's
total return in a strong market, the converse also is true. (For a more complete
discussion of the benefits and risks of leveraging, see page 2 of this report to
shareholders.)

How would you characterize the Fund's position at the close of the period?

The Fund had an average credit rating of B at the end of the period, consistent
with the rating of the Credit Suisse High Yield Index and unchanged from the
beginning of the period. At November 30, 2006, the portfolio's largest
overweights relative to the benchmark were in the media -- non-cable, gaming and
paper sectors. The Fund's primary underweights were in the automotive,
supermarkets and entertainment industries.

Our holdings in floating rate securities, including bank loans, totaled 1.6% of
non-cash investments at period-end.

16    BLACKROCK CORPORATE HIGH YIELD FUND III, INC.   NOVEMBER 30, 2006


Notes to Financial Statements

1. Significant Accounting Policies:

On September 29, 2006, Corporate High Yield Fund III, Inc. was renamed BlackRock
Corporate High Yield Fund III, Inc. (the "Fund"). The Fund is registered under
the Investment Company Act of 1940, as amended, as a diversified, closed-end
management investment company. The Fund's financial statements are prepared in
conformity with U.S. generally accepted accounting principles, which may require
the use of management accruals and estimates. Actual results may differ from
these estimates. These unaudited financial statements reflect all adjustments,
which are, in the opinion of management, necessary to present a fair statement
of the results for the interim period. All such adjustments are of a normal,
recurring nature. The Fund determines and makes available for publication the
net asset value of its Common Stock on a daily basis. The Fund's Common Stock
shares are listed on the New York Stock Exchange ("NYSE") under the symbol CYE.
The following is a summary of significant accounting policies followed by the
Fund.

(a) Valuation of investments -- Debt securities are traded primarily in the
over-the-counter ("OTC") markets and are valued at the last available bid price
in the OTC market or on the basis of values obtained by a pricing service.
Floating rate loan interests are valued at the mean between the last available
bid and asked prices from one or more brokers or dealers as obtained by a
pricing service. Pricing services use valuation matrixes that incorporate both
dealer-supplied valuations and valuation models. The procedures of the pricing
service and its valuations are reviewed by the officers of the Fund under the
general direction of the Board of Directors. Such valuations and procedures will
be reviewed periodically by the Board of Directors of the Fund. Financial
futures contracts and options thereon, which are traded on exchanges, are valued
at their closing prices as of the close of such exchanges. Options written or
purchased are valued at the last sale price in the case of exchange-traded
options. Options traded in the OTC market are valued at the last asked price
(options written) or the last bid price (options purchased). Swap agreements are
valued based upon quoted fair valuations received daily by the Fund from a
pricing service or counterparty. Short-term investments with a remaining
maturity of 60 days or less are valued at amortized cost, which approximates
market value, under which method the investment is valued at cost and any
premium or discount is amortized on a straight line basis to maturity. Valuation
of other short-term investment vehicles is generally based on the net asset
value of the underlying investment vehicle or amortized cost. Repurchase
agreements are valued at cost plus accrued interest. Investments in open-end
investment companies are valued at their net asset value each business day.
Securities and other assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
direction of the Board of Directors of the Fund.

Equity securities held by the Fund that are traded on stock exchanges or the
NASDAQ Global Market are valued at the last sale price or official close price
on the exchange, as of the close of business on the day the securities are being
valued or, lacking any sales, at the last available bid price for long
positions, and at the last available asked price for short positions. In cases
where equity securities are traded on more than one exchange, the securities are
valued on the exchange designated as the primary market by or under the
authority of the Board of Directors of the Fund. Long positions traded in the
OTC markets, NASDAQ Capital Market or Bulletin Board are valued at the last
available bid price obtained from one or more dealers or pricing services
approved by the Board of Directors of the Fund. Short positions traded in the
OTC markets are valued at the last available asked price. Portfolio securities
that are traded both in the OTC markets and on a stock exchange are valued
according to the broadest and most representative market.

Generally, trading in foreign securities is substantially completed each day at
various times prior to the close of business on the NYSE. The values of such
securities used in computing the net asset value of the Fund's shares are
determined as of such times. Foreign currency exchange rates will generally be
determined as of the close of business on the NYSE. Occasionally, events
affecting the values of such securities and such exchange rates may occur
between the times at which they are determined and the close of business on the
NYSE that may not be reflected in the computation of the Fund's net asset value.
If events (for example, a company announcement, market volatility or a natural
disaster) occur during such periods that are expected to materially affect the
value of such securities, those securities may be valued at their fair value as
determined in good faith by the Fund's Board of Directors or by BlackRock
Advisors, Inc. (the "Manager"), an indirect, wholly owned subsidiary of
BlackRock, Inc., using a pricing service and/or procedures approved by the
Fund's Board of Directors.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies both to increase the return of the Fund and to hedge, or
protect, its exposure to interest rate movements and movements in the securities
markets. Losses may arise due to changes in the


      BLACKROCK CORPORATE HIGH YIELD FUND III, INC.   NOVEMBER 30, 2006       17


Notes to Financial Statements (continued)

value of the contract or if the counterparty does not perform under the
contract.

o     Options -- The Fund may write and purchase call and put options. When the
      Fund writes an option, an amount equal to the premium received by the Fund
      is reflected as an asset and an equivalent liability. The amount of the
      liability is subsequently marked-to-market to reflect the current market
      value of the option written. When a security is purchased or sold through
      an exercise of an option, the related premium paid (or received) is added
      to (or deducted from) the basis of the security acquired or deducted from
      (or added to) the proceeds of the security sold. When an option expires
      (or the Fund enters into a closing transaction), the Fund realizes a gain
      or loss on the option to the extent of the premiums received or paid (or
      gain or loss to the extent the cost of the closing transaction exceeds the
      premium paid or received).

      Written and purchased options are non-income producing investments.

o     Financial futures contracts -- The Fund may purchase or sell financial
      futures contracts and options on such financial futures contracts.
      Financial futures contracts are contracts for delayed delivery of
      securities at a specific future date and at a specific price or yield.
      Upon entering into a contract, the Fund deposits and maintains as
      collateral such initial margin as required by the exchange on which the
      transaction is effected. Pursuant to the contract, the Fund agrees to
      receive from or pay to the broker an amount of cash equal to the daily
      fluctuation in value of the contract. Such receipts or payments are known
      as variation margin and are recorded by the Fund as unrealized gains or
      losses. When the contract is closed, the Fund records a realized gain or
      loss equal to the difference between the value of the contract at the time
      it was opened and the value at the time it was closed.

o     Swaps -- The Fund may enter into swap agreements, which are OTC contracts
      in which the Fund and a counterparty agree to make periodic net payments
      on a specified notional amount. The net payments can be made for a set
      period of time or may be triggered by a predetermined credit event. The
      net periodic payments may be based on a fixed or variable interest rate;
      the change in market value of a specified security, basket of securities,
      or index; or the return generated by a security. These periodic payments
      received or made by the Fund are recorded in the accompanying Statement of
      Operations as realized gains or losses, respectively. Gains or losses are
      also realized upon termination of the swap agreements. Swaps are
      marked-to-market daily and changes in value are recorded as unrealized
      appreciation (depreciation). Risks include changes in the returns of the
      underlying instruments, failure of the counterparties to perform under the
      contracts' terms and the possible lack of liquidity with respect to the
      swap agreements.

(c) Foreign currency transactions -- Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets or liabilities expressed in
foreign currencies to U.S. dollars. Realized and unrealized gains or losses from
investments include the effects of foreign exchange rates on investments. The
Fund invests in foreign securities, which may involve a number of risk factors
and special considerations not present with investments in securities of U.S.
corporations.

(d) 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.

(e) Security transactions and investment income -- Security 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. The Fund amortizes all
premiums and discounts on debt securities.

(f) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

(g) Securities lending -- The Fund 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 Fund and any
additional required collateral is delivered to the Fund on the next business
day. Where the Fund receives securities as collateral for the loaned securities,
it collects a fee from the borrower. The Fund typically receives the income on
the loaned securities

18    BLACKROCK CORPORATE HIGH YIELD FUND III, INC.   NOVEMBER 30, 2006


Notes to Financial Statements (continued)

but does not receive the income on the collateral. Where the Fund receives cash
collateral, it may invest such collateral and retain the amount earned on such
investment, net of any amount rebated to the borrower. Loans of securities are
terminable at any time and the borrower, after notice, is required to return
borrowed securities within five business days. The Fund may pay reasonable
finder's, 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 Fund
could experience delays and costs in gaining access to the collateral. The Fund
also could suffer a loss where the value of the collateral falls below the
market value of the borrowed securities, in the event of borrower default or in
the event of losses on investments made with cash collateral.

(h) Recent accounting pronouncements -- In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109."
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 mutual funds, before being measured
and recognized in the financial statements. Adoption of FIN 48 is required for
fiscal years beginning after December 15, 2006. The impact on the Fund's
financial statements, if any, is currently being assessed.

In addition, 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. Management is currently evaluating the implications of
FAS 157. At this time its impact on the Fund's financial statements has not been
determined.

2. Investment Advisory Agreement and Transactions with Affiliates:

On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill
Lynch") combined Merrill Lynch's investment management business, Merrill Lynch
Investment Managers, L.P. ("MLIM"), and its affiliates, including Fund Asset
Management, L.P. ("FAM"), with BlackRock, Inc. to create a new independent
company. Merrill Lynch has a 49.8% economic interest and a 45% voting interest
in the combined company and The PNC Financial Services Group, Inc., has
approximately a 34% economic and voting interest. The new company operates under
the BlackRock name and is governed by a board of directors with a majority of
independent members.

On August 15, 2006, shareholders of the Fund approved a new Investment Advisory
Agreement with the Manager. BlackRock Advisors, Inc. was recently reorganized
into a limited liability company and renamed BlackRock Advisors, LLC. The new
Investment Advisory Agreement between the Fund and the Manager became effective
on September 29, 2006. Prior to September 29, 2006, FAM was the Manager. The
general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly
owned subsidiary of Merrill Lynch, which is the limited partner.

The Manager is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Fund. For such services, the Fund
pays a monthly fee at an annual rate of .60% of the Fund's average daily net
assets plus the proceeds of any outstanding principal borrowed. In addition, the
Manager has entered into sub-advisory agreement with BlackRock Financial
Management, Inc., an affiliate of the Manager, under which the Manager pays the
Sub-Adviser for services it provides a fee that is a percentage of the
management fee paid by the Fund to the Manager. Prior to September 29, 2006, FAM
had a Sub-Advisory Agreement with Merrill Lynch Asset Management U.K. Limited
("MLAM U.K."), an affiliate of FAM.

The Fund 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"), an affiliate of FAM and the Manager, or
its affiliates. Pursuant to that order, the Fund has retained BlackRock
Investment Management, LLC ("BIM"), an affiliate of the Manager, as the
securities lending agent for a fee based on a share of the returns on investment
of cash collateral. Prior to September 29, 2006, BIM was organized as Merrill
Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of FAM, and MLIM, LLC
was the securities lending agent. BIM may, on behalf of the Fund, invest cash
collateral received by the Fund for such loans, among other things, in a private
investment company managed by the Manager or in registered money market funds
advised by the Manager or its affiliates.

In addition, MLPF&S received $625 in commissions on the execution of portfolio
security transactions for the Fund for the six months ended November 30, 2006.

Disclosure of Investment Advisory Agreement

BlackRock Investment Advisory Agreement -- Matters Considered by the Board

The following disclosure appeared in the May 31, 2006 Annual Report of the Fund
and is the discussion referred to in "New BlackRock Sub-Advisory Agreement --
Matters Considered by the Board" below.

In connection with the Transaction between Merrill Lynch and BlackRock, the
Fund's Board of Directors considered a new investment advisory agreement (the
"New Investment Advisory Agreement") between the Fund and BlackRock Advisors,
Inc. or its successor ("BlackRock Advisors"). If the New Investment Advisory
Agreement is approved by the Fund's shareholders, it will become effective upon
the closing of the Transaction, which is expected in the third quarter of 2006.

The Board discussed the New Investment Advisory Agreement at telephonic and
in-person meetings held during April and May 2006. The Board, including the
independent directors, approved the New Investment Advisory Agreement at a
meeting held on May 9, 2006.

To assist the Board in its consideration of the New Investment Advisory
Agreement, BlackRock provided materials and information about BlackRock,
including its financial condition and asset management capabilities and
organization, and Merrill Lynch provided materials and information about the
Transaction. The independent directors, through their independent legal counsel,
also requested and received additional information from Merrill Lynch and
BlackRock in connection with their consideration of the New Investment Advisory
Agreement. The additional information was provided in advance of the May 9, 2006
meeting. In addition, the independent directors consulted with their counsel and
Fund counsel on numerous occasions, discussing, among other things, the legal
standards and certain other considerations relevant to the directors'
deliberations.

At the Board meetings, members of the Board discussed with Merrill Lynch
management and certain BlackRock representatives the Transaction, its strategic
rationale and BlackRock's general plans and intentions regarding the Fund. At
these Board meetings, representatives of Merrill Lynch and BlackRock made
presentations to and responded to questions from the Board. The directors also
inquired about the plans for and anticipated roles and responsibilities of
certain employees and officers of the Investment Adviser and certain affiliates
being transferred to BlackRock in connection with the Transaction. The
independent directors of the Board also conferred separately and with their
counsel about the Transaction and other matters related to the Transaction on a
number of occasions, including in connection with the April and May 2006
meetings. After the presentations and after reviewing the written materials
provided, the independent directors met in executive sessions with their counsel
to consider the New Investment Advisory Agreement.

In connection with the Board's review of the New Investment Advisory Agreement,
Merrill Lynch and/or BlackRock advised the directors about a variety of matters.
The advice included the following, among other matters:

o     that there is not expected to be any diminution in the nature, quality and
      extent of services provided to the Fund and its shareholders by BlackRock
      Advisors, including compliance services;

o     that operation of New BlackRock as an independent investment management
      firm will enhance its ability to attract and retain talented
      professionals;

o     that the Fund should benefit from having access to BlackRock's state of
      the art technology and risk management analytic tools, including
      investment tools, provided under the BlackRock Solutions(R) brand name;

o     that BlackRock has no present intention to alter any applicable expense
      waivers and reimbursements currently in effect and, while it reserves the
      right to do so in the future, it would seek the approval of the Board
      before making any changes;

o     that under the Transaction Agreement, Merrill Lynch and BlackRock have
      agreed to conduct, and use reasonable best efforts to cause their
      respective affiliates to conduct, their respective businesses in
      compliance with the conditions of Section 15(f) of the Investment Company
      Act of 1940 (the "1940 Act") in relation to any public funds advised by
      BlackRock or the Investment Adviser (or its affiliates), respectively; and

o     that Merrill Lynch and BlackRock would derive benefits from the
      Transaction and that, as a result, they have a different financial
      interest in the matters that were being considered than do Fund
      shareholders;

The directors considered the information provided by Merrill Lynch and BlackRock
above, and, among other factors, the following:

o     the potential benefits to Fund shareholders from being part of a combined
      fund family with BlackRock-


      BLACKROCK CORPORATE HIGH YIELD FUND III, INC.   NOVEMBER 30, 2006       21


Disclosure of Investment Advisory Agreement (continued)

      sponsored funds, including possible economies of scale and access to
      investment opportunities;

o     the reputation, financial strength and resources of BlackRock and its
      investment advisory subsidiaries and the anticipated financial strength
      and resources of New BlackRock;

o     the compliance policies and procedures of BlackRock Advisors;

o     the terms and conditions of the New Investment Advisory Agreement,
      including the fact that the schedule of the Fund's total advisory fees
      will not increase by virtue of the New Investment Advisory Agreement, but
      will remain the same;

o     that within the past year the Board performed a full annual review of the
      investment advisory agreement currently in effect for the Fund (the
      "Current Investment Advisory Agreement") as required by the 1940 Act and
      has determined that the Investment Adviser has the capabilities, resources
      and personnel necessary to provide the advisory and administrative
      services currently provided to the Fund; and that the advisory and/or
      management fees paid by the Fund, taking into account any applicable
      agreed-upon fee waivers and breakpoints, represent reasonable compensation
      to the Investment Adviser in light of the services provided, the costs to
      the Investment Adviser of providing those services, economies of scale,
      the fees and other expenses paid by similar funds (including information
      provided by Lipper, Inc. ["Lipper"]), and such other matters as the
      directors have considered relevant in the exercise of their reasonable
      judgment (the Board had most recently performed a full annual review of
      the Current Investment Advisory Agreement in November 2005); and

o     that Merrill Lynch agreed to pay all expenses of the Fund in connection
      with the Board's consideration of the New Investment Advisory Agreement
      and related agreements and all costs of shareholder approval of the New
      Investment Advisory Agreement and as a result the Fund would bear no costs
      in obtaining shareholder approval of the New Investment Advisory
      Agreement.

Certain of these considerations are discussed in more detail below.

In its review of the New Investment Advisory Agreement, the Board assessed the
nature, scope and quality of the services to be provided to the Fund by the
personnel of BlackRock Advisors and its affiliates, including administrative
services, shareholder services, oversight of fund accounting, marketing services
and assistance in meeting legal and regulatory requirements. In its review of
the New Investment Advisory Agreement, the Board also considered a range of
information in connection with its oversight of the services to be provided by
BlackRock Advisors and its affiliates. Among the matters considered were: (a)
fees (in addition to management fees) to be paid to BlackRock Advisors and its
affiliates by the Fund; (b) Fund operating expenses paid to third parties; (c)
the resources devoted to and compliance reports relating to the Fund's
investment objective, policies and restrictions, and its compliance with its
Code of Ethics and BlackRock Advisors' compliance policies and procedures; and
(d) the nature, cost and character of non-investment management services to be
provided by BlackRock Advisors and its affiliates.

In the period prior to the Board meetings to consider renewal of the Current
Investment Advisory Agreement, the Board had requested and received materials
specifically relating to the agreement. These materials included (a) information
compiled by Lipper on the fees and expenses and the investment performance of
the Fund as compared to a comparable group of funds as classified by Lipper; (b)
information comparing the Fund's market price with its net asset value per
share; (c) a discussion by the Fund's portfolio management team on investment
strategies used by the Fund during its most recent fiscal year; (d) information
on the profitability to the Investment Adviser of the Current Investment
Advisory Agreement and other payments received by the Investment Adviser and its
affiliates from the Fund; and (e) information provided by the Investment Adviser
concerning services related to the valuation and pricing of Fund portfolio
holdings, the Fund's portfolio turnover statistics, and direct and indirect
benefits to the Investment Adviser and its affiliates from their relationship
with the Fund.

In their deliberations, the directors considered information received in
connection with their most recent continuation of the Current Investment
Advisory Agreement, in addition to information provided by BlackRock and
BlackRock Advisors in connection with their evaluation of the terms and
conditions of the New Investment Advisory Agreement. The directors did not
identify any particular information that was all-important or controlling. The
directors, including a majority of the independent directors, concluded that the
terms of the New Investment Advisory Agreement are appropriate, that the fees to
be paid are reasonable in light


22    BLACKROCK CORPORATE HIGH YIELD FUND III, INC.   NOVEMBER 30, 2006


of the services to be provided to the Fund, and that the New Investment Advisory
Agreement should be approved and recommended to Fund shareholders.

Nature, Quality and Extent of Services Provided -- The Board reviewed the
nature, extent and quality of services provided by the Investment Adviser,
including the investment advisory services and the resulting performance of the
Fund, as well as the nature, quality and extent of services expected to be
provided by BlackRock Advisors. The Board focused primarily on the Investment
Adviser's advisory services and the Fund's investment performance, but also
considered certain areas in which both the Investment Adviser and the Fund
receive services as part of the Merrill Lynch complex. The Board compared the
Fund's performance -- both including and excluding the effects of the Fund's
fees and expenses -- to the performance of a comparable group of funds, and the
performance of a relevant index or combination of indexes. While the Board
reviews performance data at least quarterly, consistent with the Investment
Adviser's investment goals, the Board attaches more importance to performance
over relatively long periods of time, typically three to five years.

In evaluating the nature, quality and extent of the services to be provided by
BlackRock Advisors under the New Investment Advisory Agreement, the directors
considered, among other things, the expected impact of the Transaction on the
operations, facilities, organization and personnel of New BlackRock and how it
would affect the Fund; the ability of BlackRock Advisors to perform its duties
after the Transaction; and any anticipated changes to the current investment and
other practices of the Fund. The directors considered BlackRock's advice as to
proposed changes in portfolio management personnel of the Fund after the closing
of the Transaction.

The directors were given information with respect to the potential benefits to
the Fund and its shareholders from having access to BlackRock's state of the art
technology and risk management analytic tools, including the investment tools
provided under the BlackRock Solutions brand name.

The directors were advised that, as a result of Merrill Lynch's equity interest
in BlackRock after the Transaction, the Fund will continue to be subject to
restrictions concerning certain transactions involving Merrill Lynch affiliates
(for example, transactions with a Merrill Lynch broker-dealer acting as
principal) absent revised or new regulatory relief. The directors were advised
that a revision of existing regulatory relief with respect to these restrictions
was being sought from the Securities and Exchange Commission and were advised of
the possibility of receipt of such revised regulatory relief. There can be no
assurance that such relief will be obtained.

Based on their review of the materials provided and the assurances they had
received from the management of Merrill Lynch and of BlackRock, the directors
determined that the nature and quality of services to be provided to the Fund
under the New Investment Advisory Agreement were expected to be as good or
better than that provided under the Current Investment Advisory Agreement. It
was noted, however, that it is expected that there will be changes in personnel
following the Transaction and the combination of the operations of the
Investment Adviser and its affiliates with those of BlackRock. The directors
noted that if current portfolio managers or other personnel cease to be
available, the Board would consider all available options, which could include
seeking the investment advisory or other services of BlackRock affiliates.
Accordingly, the directors concluded that, overall, they were satisfied at the
present time with assurances from BlackRock and BlackRock Advisors as to the
expected nature, extent and quality of the services to be provided to the Fund
under the New Investment Advisory Agreement.

Costs of Services Provided and Profitability -- It was noted that, in
conjunction with the recent review of the Current Investment Advisory Agreement,
the directors had received, among other things, a report from Lipper comparing
the Fund's fees, expenses and performance to those of a peer group selected by
Lipper, and information as to the fees charged by the Investment Adviser or its
affiliates to other registered investment company clients for investment
management services. The Board reviewed the Fund's contractual management fee
rate and actual management fee rate as a percentage of total assets at common
asset levels -- the actual rate includes advisory fees and the effects of any
fee waivers -- compared to the other funds in its Lipper category. They also
compared the Fund's total expenses to those of other comparable funds. The
information showed that the Fund had fees and expenses within the range of fees
and expenses of comparable funds. The Board considered the services to be
provided by and the fees to be charged by BlackRock Advisors to other funds with
similar investment mandates and noted that the fees charged by BlackRock
Advisors in those cases, including fee waivers and expense reimbursements, were
generally comparable to those being charged to the Fund. The Board also noted
that, as a general matter, according to the information provided by BlackRock,
fees charged to institutional clients were lower than the fees


      BLACKROCK CORPORATE HIGH YIELD FUND III, INC.   NOVEMBER 30, 2006       23


Disclosure of Investment Advisory Agreement (concluded)

charged to the Fund, but BlackRock Advisors provided less extensive services to
such clients. The Board concluded that the Fund's management fee and fee rate
and overall expense ratio are reasonable compared to those of other comparable
funds.

In evaluating the costs of the services to be provided by BlackRock Advisors
under the New Investment Advisory Agreement, the directors considered, among
other things, whether advisory fees or other expenses would change as a result
of the Transaction. Based on their review of the materials provided and the fact
that the New Investment Advisory Agreement is substantially similar to the
Current Investment Advisory Agreement in all material respects, including the
rate of compensation, the directors determined that the Transaction should not
increase the total fees payable, including any fee waivers and expense
reimbursements, for advisory and administrative services. The directors noted
that it was not possible to predict how the Transaction would affect BlackRock
Advisors' profitability from its relationship with the Fund.

The directors discussed with BlackRock Advisors its general methodology to be
used in determining its profitability with respect to its relationship with the
Fund. The directors noted that they expect to receive profitability information
from BlackRock Advisors on at least an annual basis and thus be in a position to
evaluate whether any adjustments in Fund fees and/or fee breakpoints would be
appropriate.

Fees and Economies of Scale -- The Board 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 management fee rate or structure in order
to enable the Fund to participate in these economies of scale. The Board
considered economies of scale to the extent applicable to the Fund's closed-end
structure and determined that the Fund currently appropriately benefits from any
economies of scale and no changes were currently necessary.

In reviewing the Transaction, the directors considered, among other things,
whether advisory fees or other expenses would change as a result of the
Transaction. Based on the fact that the New Investment Advisory Agreement is
substantially similar to the Current Investment Advisory Agreement in all
material respects, including the rate of compensation, the directors determined
that as a result of the Transaction, the Fund's total advisory fees would be no
higher than the fees under its Current Investment Advisory Agreement. The
directors noted that in conjunction with their most recent deliberations
concerning the Current Investment Advisory Agreement, the directors had
determined that the total fees for advisory and administrative services for the
Fund were reasonable in light of the services provided. It was noted that in
conjunction with the recent review of the Current Investment Advisory Agreement,
the directors had received, among other things, a report from Lipper comparing
the Fund's fees, expenses and performance to those of a peer group selected by
Lipper, and information as to the fees charged by the Investment Adviser or its
affiliates to other registered investment company clients for investment
management services. The directors concluded that, because the rates for
advisory fees for the Fund would be no higher than its current fee rates, the
proposed management fee structure, including any fee waivers, was reasonable and
that no additional changes were currently necessary.

Fall-Out Benefits -- In evaluating the fall-out benefits to be received by
BlackRock Advisors under the New Investment Advisory Agreement, the directors
considered whether the Transaction would have an impact on the fall-out benefits
received by the Investment Adviser by virtue of the Current Investment Advisory
Agreement. Based on their review of the materials provided, including materials
received in connection with their most recent approval or continuance of the
Current Investment Advisory Agreement, and their discussions with management of
the Investment Adviser and BlackRock, the directors determined that those
benefits could include increased ability for BlackRock to distribute shares of
its funds and other investment products. The directors noted that any such
benefits were difficult to quantify with certainty at this time, and indicated
that they would continue to evaluate them going forward.

Investment Performance -- The directors considered investment performance for
the Fund. The directors compared the Fund's performance -- both including and
excluding the effects of the Fund's fees and expenses -- to the performance of a
comparable group of funds, and the performance of a relevant index or
combination of indexes. The comparative information received from Lipper showed
Fund performance at various levels within the range of performance of comparable
funds over different time periods. While the Board reviews performance data at
least quarterly, consistent with the Investment Adviser's investment goals, the
Board attaches more importance over relatively long periods of time, typically
three to five years. The directors believed the Fund's performance was
satisfactory. Also, the directors took into account the investment performance
of funds currently advised by BlackRock Advisors. The Board considered


24    BLACKROCK CORPORATE HIGH YIELD FUND III, INC.   NOVEMBER 30, 2006


comparative information from Lipper which showed that the performance of the
funds advised by BlackRock Advisors was within the range of performance of
comparable funds over different time periods. The Board also noted that,
following the close of the Transaction, BlackRock Advisors intended to implement
steps to seek to improve the investment performance of the Fund. It was noted
that these steps include changes in the portfolio management personnel. The
Board noted BlackRock's considerable investment management experience and
capabilities, but were unable to predict what effect, if any, consummation of
the Transaction would have on the future performance of the Fund.

Conclusion -- After the independent directors of the Fund deliberated in
executive session, the entire Board, including the independent directors,
approved the New Investment Advisory Agreement, concluding that the advisory fee
rate was reasonable in relation to the services provided and that the New
Investment Advisory Agreement was in the best interests of the shareholders. In
approving the New Investment Advisory Agreement, the Board noted that it
anticipated reviewing the continuance of the agreement in advance of the
expiration of the initial two-year period.

Contingent BlackRock Sub-Advisory Agreement -- Matters Considered by the Board

At the telephonic and in-person meetings held during April and May 2006 at which
the Board of Directors discussed and approved the New Investment Advisory
Agreement, the Board, including the independent directors, also discussed and
approved a contingent sub-advisory agreement (the "Contingent Sub-Advisory
Agreement") between the Investment Adviser and BlackRock Advisors (the
"BlackRock Sub-Adviser"). The Contingent Sub-Advisory Agreement is intended to
ensure that the Fund operates with efficient portfolio management services until
the closing of the Transaction, in the event that the Board deems it necessary
and in the best interests of the Fund and its shareholders that the BlackRock
Sub-Adviser assist in managing the operations of the Fund during the interim
period until the closing of the Transaction. If shareholders approve the
Contingent Sub-Advisory Agreement, it will take effect only upon recommendation
from the Investment Adviser and upon subsequent approval of the Board in the
period up to the closing of the Transaction. The effectiveness of the Contingent
Sub-Advisory Agreement, therefore, would be contingent on further Board approval
after shareholders approve it. Pursuant to the Contingent Sub-Advisory
Agreement, the BlackRock Sub-Adviser would receive a monthly fee from the
Investment Adviser equal to 50% of the advisory fee received by the Investment
Adviser. The Investment Adviser would pay the BlackRock Sub-Adviser out of its
own resources. There would be no increase in Fund expenses as a result of the
Contingent Sub-Advisory Agreement.

In making its approval, the Board considered the Contingent Sub-Advisory
Agreement in conjunction with the New Investment Advisory Agreement and reviewed
the same information and factors discussed above, and came to the same
conclusions. The Board also considered in conjunction with the Contingent
Sub-Advisory Agreement the necessity of ensuring that the Fund operates with
effective management services until the closing of the Transaction. In reviewing
the sub-advisory fee rate provided in the Contingent Sub-Advisory Agreement, the
Board took note of the fact that both the Investment Adviser and the BlackRock
Sub-Adviser would have significant responsibilities under their respective
advisory agreements. The Investment Adviser would remain responsible for
oversight of the Fund's operations and administration and the BlackRock
Sub-Adviser would provide advisory services to the Fund under the Contingent
Sub-Advisory Agreement. The Board also took into account the expected short
duration of the term of any Contingent Sub-Advisory Agreement and the fact that
total advisory fees paid by the Fund would not increase as a result of the
Contingent Sub-Advisory Agreement. Under all of the circumstances, the Board
concluded that it was a reasonable allocation of fees for the BlackRock
Sub-Adviser to receive 50% of the advisory fee paid by the Fund to the
Investment Adviser.

After the independent directors deliberated in executive session, the entire
Board, including the independent directors, approved the Contingent Sub-Advisory
Agreement, concluding that the advisory fee was reasonable in relation to the
services provided and that the Contingent Sub-Advisory Agreement was in the best
interests of shareholders.

Disclosure of Sub-Advisory Agreement

New BlackRock Sub-Advisory Agreement -- Matters Considered by the Board

At an in-person meeting held on August 22-23, 2006, the Board of Directors,
including the independent directors, discussed and approved the sub-advisory
agreement between BlackRock Advisors and its affiliate, BlackRock Financial
Management, Inc. (the "Sub-Adviser") (the "BlackRock Sub-Advisory Agreement").
The BlackRock Sub-Advisory Agreement became effective on September 29, 2006, at
the same time the New Investment Advisory Agreement with BlackRock Advisors
(which had been approved by the Fund's shareholders) became effective.

Pursuant to the BlackRock Sub-Advisory Agreement, the Sub-Adviser receives a
monthly fee from BlackRock Advisors equal to 59% of the advisory fee received by
BlackRock Advisors from the Fund. BlackRock Advisors pays the Sub-Adviser out of
its own resources, and there is no increase in the Fund expenses as a result of
the BlackRock Sub-Advisory Agreement.

In approving the BlackRock Sub-Advisory Agreement at the August in-person
meeting, the Board reviewed its considerations in connection with its approval
of the New Investment Advisory Agreement in May 2006. The Board relied on the
same information and considered the same factors as those discussed above in
connection with the approval of the New Investment Advisory Agreement, and came
to the same conclusions. In reviewing the sub-advisory fee rate provided for in
the BlackRock Sub-Advisory Agreement, the Board noted the fact that both
BlackRock Advisors and the Sub-Adviser have significant responsibilities under
their respective advisory agreements. Under the New Investment Advisory
Agreement, BlackRock Advisors remains responsible for the overall management of
the Fund and for oversight of the Fund's operations and administration. Under
the BlackRock Sub-Advisory Agreement, the Sub-Adviser provides advisory services
to the Fund and is responsible for the day-to-day management of the Fund's
portfolio. The Board also took into account the fact that there is no increase
in total advisory fees paid by the Fund as a result of the BlackRock
Sub-Advisory Agreement. Based on its considerations, the Board concluded that it
was a reasonable allocation of fees for the Sub-Adviser to receive 59% of the
advisory fee paid by the Fund to BlackRock Advisors.

After the independent directors deliberated in executive session, the entire
Board of the Fund, including the independent directors, approved the BlackRock
Sub-Advisory Agreement, concluding that the sub-advisory fee was reasonable in
relation to the services provided and that the BlackRock Sub-Advisory Agreement
was in the best interests of the Fund's shareholders.

         (iv) Potential Material Conflicts of Interest

         BlackRock has built a professional working environment, firm-wide
         compliance culture and compliance procedures and systems designed to
         protect against potential incentives that may favor one account over
         another. BlackRock has adopted policies and procedures that address the
         allocation of investment opportunities, execution of portfolio
         transactions, personal trading by employees and other potential
         conflicts of interest that are designed to ensure that all client
         accounts are treated equitably over time. Nevertheless, BlackRock
         furnishes investment management and advisory services to numerous
         clients in addition to the Fund, and BlackRock may, consistent with
         applicable law, make investment recommendations to other clients or
         accounts (including accounts which are hedge funds or have performance
         or higher fees paid to BlackRock, or in which portfolio managers have a
         personal interest in the receipt of such fees), which may be the same
         as or different from those made to the Fund. In addition, BlackRock,
         its affiliates and any officer, director, stockholder or employee may
         or may not have an interest in the securities whose purchase and sale
         BlackRock recommends to the Fund. BlackRock, or any of its affiliates,
         or any officer, director, stockholder, employee or any member of their
         families may take different actions than those recommended to the Fund
         by BlackRock with respect to the same securities. Moreover, BlackRock
         may refrain from rendering any advice or services concerning securities
         of companies of which any of BlackRock's (or its affiliates') officers,
         directors or employees are directors or officers, or companies as to
         which BlackRock or any of its affiliates or the officers, directors and
         employees of any of them has any substantial economic interest or
         possesses material non-public information. Each portfolio manager also
         may manage accounts whose investment strategies may at times be opposed
         to the strategy utilized for the Fund. In this connection, it should be
         noted that certain portfolio managers currently manage certain accounts



         that are subject to performance fees. In addition, certain portfolio
         managers assist in managing certain hedge funds and may be entitled to
         receive a portion of any incentive fees earned on such funds and a
         portion of such incentive fees may be voluntarily or involuntarily
         deferred. Additional portfolio managers may in the future manage other
         such accounts or funds and may be entitled to receive incentive fees.

         As a fiduciary, BlackRock owes a duty of loyalty to its clients and
         must treat each client fairly. When BlackRock purchases or sells
         securities for more than one account, the trades must be allocated in a
         manner consistent with its fiduciary duties. BlackRock attempts to
         allocate investments in a fair and equitable manner among client
         accounts, with no account receiving preferential treatment. To this
         end, BlackRock has adopted a policy that is intended to ensure that
         investment opportunities are allocated fairly and equitably among
         client accounts over time. This policy also seeks to achieve reasonable
         efficiency in client transactions and provide BlackRock with sufficient
         flexibility to allocate investments in a manner that is consistent with
         the particular investment discipline and client base.

         (a)(3) As of December 31, 2006:

         Portfolio Manager Compensation

         BlackRock's financial arrangements with its portfolio managers, its
         competitive compensation and its career path emphasis at all levels
         reflect the value senior management places on key resources.
         Compensation may include a variety of components and may vary from year
         to year based on a number of factors. The principal components of
         compensation include a base salary, a discretionary bonus,
         participation in various benefits programs and one or more of the
         incentive compensation programs established by BlackRock such as its
         Long-Term Retention and Incentive Plan and Restricted Stock Program.

         Base compensation

         Generally, portfolio managers receive base compensation based on their
         seniority and/or their position with the firm.

         Discretionary compensation

         In addition to base compensation, portfolio managers may receive
         discretionary compensation, which can be a substantial portion of total
         compensation. Discretionary compensation can include a discretionary
         cash bonus as well as one or more of the following:

         Long-Term Retention and Incentive Plan (LTIP)

         The LTIP is a long-term incentive plan that seeks to reward certain key
         employees. The plan provides for the grant of awards that are expressed
         as an amount of cash that, if properly vested and subject to the
         attainment of certain performance goals, will be settled in cash and/or
         in BlackRock, Inc. common stock.

         Deferred Compensation Program

         A portion of the compensation paid to each portfolio manager may be
         voluntarily deferred by the portfolio manager into an account that
         tracks the performance of certain of the firm's investment products.
         Each portfolio manager is permitted to allocate his deferred amounts
         among various options, including to certain of the firm's hedge funds
         and other unregistered products. In addition, prior to 2005, a portion



         of the annual compensation of certain senior managers was mandatorily
         deferred in a similar manner for a number of years. Beginning in 2005,
         a portion of the annual compensation of certain senior managers was
         paid in the form of BlackRock, Inc. restricted stock units which vest
         ratably over a number of years.

         Options and Restricted Stock Awards

         While incentive stock options are not currently being awarded to
         BlackRock employees, BlackRock, Inc. previously granted stock options
         to key employees, including certain portfolio managers who may still
         hold unexercised or unvested options. BlackRock, Inc. also has a
         restricted stock award program designed to reward certain key employees
         as an incentive to contribute to the long-term success of BlackRock.
         These awards vest over a period of years.

         Incentive Savings Plans

         BlackRock, Inc. has created a variety of incentive savings plans in
         which BlackRock employees are eligible to participate, including an
         Employee Stock Purchase Plan (ESPP) and a 401(k) plan. The 401(k) plan
         may involve a company match of the 50% employee's pre-tax contribution
         of up to 6% of the employee's salary, limited to $4,000 per year.
         BlackRock also offers a Company Retirement Contribution equal to 3% to
         5% of eligible compensation, depending on BlackRock, Inc.'s overall net
         operating income. The company match is made in cash. The firm's 401(k)
         plan offers a range of investment options, including registered
         investment companies managed by the firm. Each portfolio manager is
         eligible to participate in these plans.

         Annual incentive compensation for each portfolio manager is a function
         of several components: the performance of BlackRock, Inc., the
         performance of the portfolio manager's group within BlackRock, the
         investment performance, including risk-adjusted returns and income
         generation, of the firm's assets under management or supervision by
         that portfolio manager relative to predetermined benchmarks, and the
         individual's teamwork and contribution to the overall performance of
         these portfolios and BlackRock. Unlike many other firms, portfolio
         managers at BlackRock compete against benchmarks rather than each
         other. In most cases, including for the portfolio managers of the
         Registrant, these benchmarks are the same as the benchmark or
         benchmarks against which the investment performance, including
         risk-adjusted returns and income generation, of the Registrant or other
         accounts are measured. These benchmarks include customized benchmarks,
         Lipper peer groups and a subset of other closed-end taxable debt funds.
         A group of BlackRock, Inc.'s officers determines which benchmarks
         against which to compare the performance of funds and other accounts
         managed by each portfolio manager. With respect to the Registrant, such
         benchmarks include Customized Index and standard list.

         The group of BlackRock, Inc.'s officers then makes a subjective
         determination with respect to the portfolio manager's compensation
         based on the performance of the funds and other accounts managed by
         each portfolio manager relative to the various benchmarks. This
         determination may take into consideration the fact that a benchmark may
         not perfectly correlate to the way the Registrant or other accounts are
         managed, even if it is the benchmark that is most appropriate for the
         Registrant or other account. For example, a benchmark's return may be
