A Letter to Shareholders

Dear Shareholder

For much of the reporting period, investors grappled with the repercussions of
the credit crisis that surfaced last summer, and with the effects of a weakening
economy and surging energy and food prices. These factors were offset by the
positive impact from robust export activity, strength in the non-financial
corporate sector and monetary and fiscal stimuli.

Amid the market turbulence, the Federal Reserve Board (the "Fed") initiated a
series of moves to restore liquidity and bolster financial market stability.
Since September 2007, the central bank slashed the target federal funds rate 325
basis points (3.25%), bringing the rate to 2.0% as of period-end. Also of
significance were its other policy decisions, which included extending use of
the discount window to broker-dealers and investment banks and backstopping the
rescue of ill-fated Bear Stearns. Notably, on April 30, the Fed dropped previous
references to downside growth risks and added more emphasis on inflationary
pressures, indicating the central bankers have likely concluded the current
cycle of monetary easing.

Nevertheless, the Fed's response to the financial crisis helped to ease credit
turmoil and investor anxiety. Since hitting a low point on March 17, following
the collapse of Bear Stearns, stocks appreciated 10% (through May 30). Most
international markets, which had outperformed U.S. stocks for some time, saw a
reversal in that trend, as the troubled credit situation and downward pressures
on growth fanned recession fears.

In fixed income markets, Treasury securities rallied (yields fell as prices
correspondingly rose), as a broad "flight-to-quality" theme persisted. The yield
on 10-year Treasury issues, which touched 5.30% in June 2007 (its highest level
in five years), fell to a low of 3.34% in March 2008 before rising to 4.06% by
May 31 as investors grew more risk tolerant and shifted out of Treasury issues
in favor of stocks and other high-quality fixed income sectors. Tax-exempt
issues under-performed throughout most of the reporting period, pressured by
problems among municipal bond insurers and the freeze in the market for auction
rate securities. However, the final two months saw a firmer tone in the
municipal market, as investors took advantage of unusually high yields.

On the whole, results for the major benchmark indexes generally reflected
heightened investor risk aversion:

Fund Summary as of May 31, 2008

--------------------------------------------------------------------------------
Investment Objective
--------------------------------------------------------------------------------

      BlackRock Corporate High Yield Fund III, Inc. (CYE) (the "Fund") seeks to
      provide shareholders with current income by investing primarily in a
      diversified portfolio of fixed income securities that are rated in the
      lower rating categories of the established rating services (Ba or lower by
      Moody's Investors Service, Inc. or BB or lower by Standard & Poor's
      Corporation) or are unrated securities of comparable quality.

--------------------------------------------------------------------------------
Performance
--------------------------------------------------------------------------------

      For the 12 months ended May 31, 2008, the Fund returned (8.30%) based on
      market price and (5.69%) based on net asset value ("NAV"). For the same
      period, the closed-end Lipper High Current Yield Funds (Leveraged)
      category posted an average return of (15.00%) on a NAV basis. All returns
      reflect reinvestment of dividends. In an adverse high yield market, the
      Fund was defensively positioned, on average, and maintained less leverage
      than many of its Lipper peers. A small allocation to bank loans was added
      during the period and detracted from performance, as bank loans
      underperformed. The Fund's discount to NAV widened to 7.74% by period-end.

            The views expressed reflect the opinions of BlackRock as of the date
            of this 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 are no guarantee of future results.

================================================================================

The Benefits and Risks of Leveraging

The Fund utilizes leverage through borrowings or issuance of short-term debt
securities. 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. To the extent that 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 will
benefit from the incremental yield.

Leverage creates risks for Common Stock shareholders including the likelihood of
greater NAV and market price volatility. In addition, there is the risk that
fluctuations in interest rates on borrowings may reduce the Common Stock's yield
and negatively impact its NAV 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.

Under the Investment Act of 1940, the Fund is permitted to borrow through a
credit facility or the issuance of short-term debt securities in an amount up to
33 (1)/3% of its total managed assets. As of May 31, 2008, the Fund had
outstanding leverage from credit facility borrowings of 20% of its total managed
assets.

--------------------------------------------------------------------------------
Swap Agreements
--------------------------------------------------------------------------------

The Fund may invest in swap agreements, which are over-the-counter contracts in
which one party agrees to make periodic payments based on the change in market
value of a specified bond, basket of bonds or index in return for periodic
payments based on a fixed or variable interest rate or the change in market
value of a different bond, basket of bonds or index. Swap agreements may be used
to obtain exposure to a bond or market without owning or taking physical custody
of securities. Swap agreements involve the risk that the party with whom the
Fund has entered into the swap will default on its obligation to pay the Fund
and the risk that the Fund will not be able to meet its obligations to pay the
other party to the agreement.

        BLACKROCK CORPORATE HIGH YIELD FUND III, INC.       MAY 31, 2008      15



================================================================================

Notes to Financial Statements

1. Significant Accounting Policies:

BlackRock Corporate High Yield Fund III, Inc. (the "Fund") is registered under
the Investment Company Act of 1940, as amended (the "1940 Act"), as a
diversified, closed-end management investment company. 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 Fund determines and makes available for publication the net asset
value of its Common Stock on a daily basis.

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

Valuation of Investments: The Fund values its corporate 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 Directors (the "Board"). Floating rate loan interests are valued at the mean
between the last available bid prices from one or more brokers or dealers as
obtained from a pricing service. 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. Swap agreements
are valued by quoted fair values received daily by the Fund's pricing service.
Short-term securities are valued at amortized cost. Investments in open-end
investment companies are valued at net asset value each business day.

Equity investments traded on a recognized securities exchange or on the NASDAQ
Global Market System are valued at the last reported sale price that day or the
NASDAQ official closing price, if applicable. Equity investments traded on a
recognized securities exchange for which there were no sales on that day are
valued at the last available bid price.

Exchange-traded options are valued at the mean between the last bid and ask
prices at the close of the options market in which the options trade.
Over-the-counter ("OTC") options are valued by an independent pricing service
using a mathematical model that incorporates a number of market data factors.

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.

Generally, trading in foreign securities is substantially completed each day at
various times prior to the close of business on the New York Stock Exchange
("NYSE"). The values of such securities used in computing the net assets of the
Fund are determined as of such times. Foreign currency exchange rates will 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 assets. 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 Board or by the investment advisor using a
pricing service and/or procedures approved by the Board.

Derivative Financial Instruments: The Fund may engage in various portfolio
investment strategies 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 if the value of the contract decreases due to an
unfavorable change in the price of the underlying security or if the
counterparty does not perform under the contract.

o     Forward foreign currency contracts -- The Fund may enter into forward
      foreign currency contracts as a hedge against either specific transactions
      or portfolio positions. Forward currency contracts, when used by the Fund,
      help to manage the overall exposure to the foreign currency backing some
      of the investments held by the Fund. The contract is marked-to-market
      daily and the change in market value is recorded by the Fund as an
      unrealized gain or loss. When the contract is closed, the Fund records a
      realized gain or loss equal to the difference between the value at the
      time it was opened and the value at the time it was closed.

o     Options -- The Fund may purchase and write 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 received or paid).


16      BLACKROCK CORPORATE HIGH YIELD FUND III, INC.       MAY 31, 2008



================================================================================

Notes to Financial Statements (continued)

      A call option gives the purchaser of the option the right (but not the
      obligation) to buy, and obligates the seller to sell (when the option is
      exercised), the underlying position at the exercise price at any time or
      at a specified time during the option period. A put option gives the
      holder the right to sell and obligates the writer to buy the underlying
      position at the exercise price at any time or at a specified time during
      the option period.

o     Credit default swaps -- The Fund may invest in credit default swaps, which
      are agreements in which one party pays fixed periodic payments to a
      counterparty in consideration for a guarantee from the counter-party to
      make a specific payment should a negative credit event take place. 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 realized upon termination of the swap
      agreements. Swaps are marked-to-market daily and changes in value are
      recorded as unrealized appreciation (depreciation). When the swap is
      terminated, the Fund will record a realized gain or loss equal to the
      difference between the proceeds from (or cost of) the closing transaction
      and the Fund's basis in the contract, if any.

Foreign Currency Transactions: Foreign currency amounts are translated into
United States dollars on the following basis: (i) market value of investment
securities, assets and liabilities at the current rate of exchange; and (ii)
purchases and sales of investment securities, income and expenses at the rates
of exchange prevailing on the respective dates of such transactions.

The Fund reports foreign currency related transactions as components of realized
gains for financial reporting purposes, whereas such components are treated as
ordinary income for federal income tax purposes.

Floating Rate Loans: The Fund invests in floating rate loans, which are
generally non-investment grade, made by banks, other financial institutions and
privately and publicly offered corporations. Floating rate loans generally pay
interest at rates that are periodically determined by reference to a base
lending rate plus a premium. The base lending rates are generally (i) the
lending rate offered by one or more European banks, such as LIBOR (London
InterBank Offered Rate), (ii) the prime rate offered by one or more U.S. banks
or (iii) the certificate of deposit rate. The Fund considers these investments
to be investments in debt securities for purposes of its investment policies.

The Fund earns and/or pays facility and other fees on floating rate loans. Other
fees earned/paid include commitment, amendment, consent, commissions and
prepayment penalty fees. Facility, amendment and consent fees are typically
amortized as premium and/or accreted as discount over the term of the loan.
Commitment, commission and various other fees are recorded as income or expense.
Prepayment penalty fees are recognized on the accrual method. When the Fund buys
a floating rate loan it may receive a facility fee and when it sells a floating
rate loan it may pay a facility fee. On an ongoing basis, a Fund may receive a
commitment fee based on the undrawn portion of the underlying line of credit
portion of a floating rate loan. In certain circumstances, a Fund may receive a
prepayment penalty fee upon the prepayment of a floating rate loan by a
borrower. Other fees received by a Fund may include covenant waiver fees and
covenant modification fees.

The Fund may invest in multiple series or tranches of a loan. A different series
or tranche may have varying terms and carry different associated risks.

Floating rate loans are usually freely callable at the issuer's option. The Fund
may invest in such loans in the form of participations in loans
("Participations") and assignments of all or a portion of loans from third
parties. Participations typically will result in the Fund having a contractual
relationship only with the lender, not with the borrower.

The Fund will have the right to receive payments of principal, interest and any
fees to which it is entitled only from the lender selling the Participation and
only upon receipt by the lender of the payments from the borrower. In connection
with purchasing Participations, the Fund generally will have no right to enforce
compliance by the borrower with the terms of the loan agreement relating to the
loans, nor any rights of offset against the borrower, and the Fund may not
benefit directly from any collateral supporting the loan in which it has
purchased the Participation.

As a result, the Fund will assume the credit risk of both the borrower and the
lender that is selling the Participation. The Fund's investments in loan
participation interests involve the risk of insolvency of the financial
intermediaries who are parties to the transactions. In the event of the
insolvency of the lender selling the Participation, the Fund may be treated as a
general creditor of the lender and may not benefit from any offset between the
lender and the borrower.

Capital Trusts: These securities are typically issued by corporations, generally
in the form of interest-bearing notes with preferred securities characteristics,
or by an affiliated business trust of a corporation, generally in the form of
beneficial interests in subordinated debentures or similarly structured
securities. The securities can be structured as either fixed or adjustable
coupon securities that can have either a perpetual or stated maturity date.
Dividends can be deferred without creating an event of default or acceleration,
although maturity cannot take place unless all cumulative payment obligations
have been met. The deferral of payments does not affect the purchase or sale of
these securities in the open market. Payments on these securities are treated as
interest rather than dividends for Federal income tax purposes. These securities
can have a rating that is slightly below that of the issuing company's senior
debt securities.

Preferred Stock: The Fund may invest in preferred stocks. Preferred stock has a
preference over common stock in liquidation (and generally in receiving
dividends as well) but is subordinated to the liabilities of the issuer in all
respects. As a general rule, the market value of preferred stock


        BLACKROCK CORPORATE HIGH YIELD FUND III, INC.       MAY 31, 2008      17



================================================================================

Notes to Financial Statements (continued)

with a fixed dividend rate and no conversion element varies inversely with
interest rates and perceived credit risk, while the market price of convertible
preferred stock generally also reflects some element of conversion value.
Because preferred stock is junior to debt securities and other obligations of
the issuer, deterioration in the credit quality of the issuer will cause greater
changes in the value of a preferred stock than in a more senior debt security
with similar stated yield characteristics. Unlike interest payments on debt
securities, preferred stock dividends are payable only if declared by the
issuer's board of directors. Preferred stock also may be subject to optional or
mandatory redemption provisions.

Segregation: In cases in which the 1940 Act and the interpretive positions of
the Securities and Exchange Commission ("SEC") require that the Fund segregate
assets in connection with certain investments (e.g., futures) and certain
borrowings, the Fund will, consistent with certain interpretive letters issued
by the SEC, designate on its books and records cash or other liquid debt
securities having a market value at least equal to the amount that would
otherwise be required to be physically segregated.

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.
Dividends from foreign securities where the ex-dividend date may have passed are
subsequently recorded when the Fund has determined the ex-dividend date.
Interest income is recognized on the accrual basis. The Fund amortizes all
premiums and discounts on debt securities.

Dividends and Distributions: Dividends from net investment income are declared
and paid monthly. Distributions of capital gains 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. Under the applicable
foreign tax laws, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

Effective November 30, 2007, 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 U.S. federal tax returns remain open for the years
ended May 31, 2005 through May 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.

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, if any, is currently being assessed.

In addition, in February 2007, Statement of Financial Accounting Standards No.
159, "The Fair Value Option for Financial Assets and Financial Liabilities"
("FAS 159"), was issued and is effective for fiscal years beginning after
November 15, 2007. FAS 159 permits entities to choose to measure many financial
instruments and certain other items at fair value that are not currently
required to be measured at fair value. FAS 159 also establishes presentation and
disclosure requirements designed to facilitate comparisons between entities that
choose different measurement attributes for similar types of assets and
liabilities. The impact on the Fund's financial statement disclosures, if any,
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 and is effective for fiscal years
beginning after November 15, 2008. 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. The impact on the Fund's financial
statement disclosures, if any, is currently being assessed.

Deferred Compensation and BlackRock Closed-End Share Equivalent Investment Plan:
Under the deferred compensation plan approved by the Fund's Board,
non-interested Directors ("Independent Directors") may defer a portion of their
annual complex-wide compensation. Deferred amounts earn an approximate return as
though equivalent dollar amounts have been invested in common shares of other
certain BlackRock Closed-End Funds selected by the Independent Directors. This
has approximately the same economic effect for the Independent Directors as if
the Independent Directors had invested the deferred amounts directly in other
certain BlackRock Closed-End Funds.


18      BLACKROCK CORPORATE HIGH YIELD FUND III, INC.       MAY 31, 2008



================================================================================

Notes to Financial Statements (continued)

The deferred compensation plan is not funded and obligations thereunder
represent general unsecured claims against the general assets of the Fund. The
Fund may, however, elect to invest in common stock of other certain BlackRock
Closed-End Funds selected by the Independent Directors in order to match its
deferred compensation obligations.

Other: Expenses directly related to the Fund are charged to that Fund. 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 Fund 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. and The PNC Financial Services Group, Inc. 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 operations of the Fund. For such services, the Fund
pays the Advisor a monthly fee at an annual rate of 0.60% of the average daily
value of the Fund's net assets plus the proceeds of any outstanding borrowings
used for leverage.

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

For the year ended May 31, 2008, the Fund reimbursed the Advisor $5,298, for
certain accounting services, which is included in accounting services in the
Statement of Operations.

Pursuant to the terms of the custody agreement, custodian fees may be reduced by
amounts calculated on uninvested cash balances, which are shown on the Statement
of Operations as fees paid indirectly.

Certain officers and/or directors of the Fund are officers and/or directors of
BlackRock, Inc. or its affiliates.

3. Investments:

Purchases and sales (including paydowns) of investments, excluding short-term
securities, for the year ended May 31, 2008 were $147,334,146 and $201,930,377,
respectively.

4. Capital Share Transactions:

The Fund is authorized to issue 200,000,000 shares of capital stock, par value
$0.10, all of which were initially classified as Common Stock. The Board is
authorized, however, to classify and reclassify any unissued shares of capital
stock without approval of the holders of Common Stock.

Shares issued and outstanding during the years ended May 31, 2008 and May 31,
2007 remained constant.

5. Short-Term Borrowings:

On May 16, 2008, the Fund renewed its revolving credit and security agreement
funded by a commercial paper asset securitization program with Citicorp North
America, Inc. ("Citicorp") as agent, certain secondary backstop lenders, and
certain asset securitization conduits as lenders (the "Lenders"). The agreement
was renewed for one year and has a maximum limit of $143,000,000. Under the
Citicorp program, the conduits will fund advances to the Fund through the
issuance of highly rated commercial paper. As security for its obligations to
the Lenders under the revolving securitization facility, the Fund has granted a
security interest in substantially all of its assets to and in favor of the
Lenders. The interest rate on the Fund's borrowings is based on the interest
rate carried by the commercial paper plus a program fee. The Fund pays
additional borrowing costs including a backstop commitment fee. These amounts
are shown on the Statement of Operations as borrowing costs.

For the year ended May 31, 2008, the daily weighted average interest rate was
5.15%.

6. Income Tax Information:

Reclassification: 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. Accordingly, during
the current year, $18,095,581 has been reclassified between paid-in capital in
excess of par and accumulated net realized capital losses, and $57,339 has been
reclassified between accumulated net realized capital losses and undistributed
net investment income as a result of permanent differences attributable to
expiration of capital loss carryforwards, amortization methods on fixed income
securities, and foreign currency transactions. These reclassifications have no
effect on net assets or net asset values per share.

Notes to Financial Statements (concluded)

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

------------------------------------------------------------------------------
                                                     5/31/2008     5/31/2007

Distributions paid from:
   Ordinary income ..............................   $28,767,885   $25,076,686
                                                    --------------------------
Total taxable distributions .....................   $28,767,885   $25,076,686
                                                    ==========================

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

------------------------------------------------------------------------------
Undistributed net ordinary income ...........................   $   3,543,427
Undistributed long-term net capital gains ...................              --
                                                                --------------
Total undistributed net earnings ............................       3,543,427
Capital loss carryforward ...................................    (208,933,784)*
Net unrealized losses .......................................     (36,679,791)**
                                                                --------------
Total accumulated net losses ................................   $(242,070,148)
                                                                ==============

 *    On May 31, 2008, the Fund had a capital loss carryforward of $208,933,784,
      of which $34,200,029 expires in 2009, $52,918,036 expires in 2010,
      $119,513,437 expires in 2011, $1,938,881 expires in 2012 and $363,401
      expires in 2016. This amount will be available to offset any future
      realized capital gains.

**    The difference between book-basis and tax-basis net unrealized losses is
      attributable primarily to the tax deferral of losses on wash sales, the
      difference between book and tax amortization methods for premiums and
      discounts on fixed income securities, the book/tax differences in the
      accrual of income on securities in default, the realization for tax
      purposes of unrealized gains (losses) on certain foreign currency
      contracts, the deferral of post-October capital losses for tax purposes,
      the accounting for swap agreements and other book/tax temporary
      differences.

7. Subsequent Event:

The Fund paid a net investment income dividend in the amount of $0.060000 per
share on June 30, 2008 to shareholders of record on June 16, 2008.

Fund III, Inc.:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of BlackRock Corporate High Yield Fund III, Inc.
(the "Fund") as of May 31, 2008, and the related statements of operations and
cash flows 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

financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

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 Fund
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 Fund'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 May
31, 2008, by correspondence with the custodian and financial intermediaries;
where replies were not received from financial intermediaries, 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 Corporate High Yield Fund III, Inc. as of May 31, 2008, the results of
its operations and its cash flows 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.

Disclosure of Investment Advisory Agreement and Subadvisory Agreement

The Board of Directors (the "Board," the members of which are referred to as
"Directors") of the BlackRock Corporate High Yield Fund III, Inc. (the "Fund")
met in April and May 2008 to consider approving the continuation of the Fund's
investment advisory agreement (the "Advisory Agreement") with BlackRock
Advisors, LLC (the "Advisor"), the Fund's investment adviser. The Board also
considered the approval of the Fund's subadvisory agreement (the "Subadvisory
Agreement" and, together with the "Advisory Agreement," the "Agreements")
between the Advisor and BlackRock Financial Management Inc. (the "Subadvisor").
The Advisor and the Subadvisor are collectively referred to herein as the
"Advisors" and, together with BlackRock, Inc., "BlackRock."

Activities and Composition of the Board

The Board of Directors of the Fund consists of thirteen individuals, eleven of
whom are not "interested persons" of the Fund as defined in the Investment
Company Act of 1940 (the "1940 Act") (the "Independent Directors"). The
Directors 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 Directors have retained independent legal counsel
to assist them in connection with their duties. The Chairman of the Board is an
Independent Director. The Board has established four standing committees: an
Audit Committee, a Governance and Nominating Committee, a Compliance Committee
and a Performance Oversight Committee.

Advisory Agreement and Subadvisory Agreement

Upon the consummation of the combination of BlackRock, Inc.'s investment
management business with Merrill Lynch & Co., Inc.'s investment management
business, including Merrill Lynch Investment Managers, L.P., and certain
affiliates, the Fund entered into the Advisory Agreement and the Subadvisory
Agreement, each with an initial two-year term. Consistent with the 1940 Act,
after the Advisory and Subadvisory Agreement's respective initial two-year term,
the Board is required to consider the continuation of the Fund's Advisory
Agreement and Subadvisory Agreement 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, secondary
market support services, oversight of fund accounting, and assistance in meeting
legal and regulatory requirements. The Board also received and assessed
information regarding the services provided to the Fund by certain unaffiliated
service providers.

Throughout the year, the Board also considered a range of information in
connection with its oversight of the services provided by BlackRock and its
affiliates. 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 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 paid to
third parties; (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 equity brokerage commissions and execution
quality; (j) valuation and liquidity procedures; and (k) reviews of BlackRock's
business, including BlackRock's response to the increasing scale of its
business.

Board Considerations in Approving the Advisory Agreement and Subadvisory
Agreement

To assist the Board in its evaluation of the Agreements, the Directors received
information from BlackRock in advance of the April 22, 2008 meeting which
detailed, among other things, the organization, business lines and capabilities
of the Advisors, including: (a) the responsibilities of various departments and
key personnel and biographical information relating to key personnel; (b)
financial statements for BlackRock; (c) the advisory and/or administrative fees
paid by the Fund to the Advisors, including comparisons, compiled by Lipper, an
independent third party, with the management fees of funds with similar
investment objectives ("Peers"); (d) the profitability of BlackRock and certain
industry profitability analyses for advisers to registered investment companies;
(e) the expenses of BlackRock in providing various services; (f) non-investment
advisory reimbursements, if applicable, and "fallout" benefits to BlackRock; (g)
economies of scale, if any, generated through the Advisors' management of all of
the BlackRock closed-end funds (the "Fund Complex"); (h) the expenses of the
Fund, including comparisons of the Fund's expense ratios (both before and after
any fee waivers) with the expense ratios of its Peers; and (i) the Fund's
performance for the past one-, three- and five-year periods, when applicable, as
well as the Fund's performance compared to its Peers.

The Board also considered other matters it deemed important to the approval
process, where applicable, 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, allocation of fund brokerage fees
(including the related benefits to BlackRock of "soft dollars") and direct and
indirect benefits to BlackRock and its affiliates from their relationship with
the Fund.

In addition to the foregoing materials, independent legal counsel to the
Independent Directors provided a legal memorandum outlining, among other things,
the duties of the Board under the 1940 Act, as well as the general principles of
relevant law in reviewing and approving advisory contracts, the requirements of
the 1940 Act in such matters, an adviser's fiduciary duty with respect to
advisory agreements and compensation,

================================================================================

Disclosure of Investment Advisory Agreement and Subadvisory Agreement
(continued)

and the standards used by courts in determining whether investment company
boards of directors have fulfilled their duties and the factors to be considered
by boards in voting on advisory agreements.

The Independent Directors reviewed this information and discussed it with
independent legal counsel prior to the meeting on April 22, 2008. At the Board
meeting on April 22, 2008, BlackRock made a presentation to and responded to
questions from the Board. Following the meeting on April 22, 2008, the Board
presented BlackRock with questions and requests for additional information.
BlackRock responded to these requests with additional written materials provided
to the Directors prior to the meetings on May 29 and 30, 2008. At the Board
meeting on May 29 and 30, 2008, BlackRock responded to further questions from
the Board. In connection with BlackRock's presentations, the Board considered
each Agreement and, in consultation with independent legal counsel, reviewed the
factors set out in judicial decisions and Securities and Exchange Commission
("SEC") statements relating to the renewal of the Agreements.

I. Matters Considered by the Board

In connection with its deliberations with respect to the Agreements, the Board
considered all factors it believed relevant with respect to the Fund, including
the following: the nature, extent and quality of the services provided by the
Advisors; the investment performance of the Fund; the costs of the services to
be provided and profits to be realized by the Advisors and their affiliates from
their relationship with the Fund; the extent to which economies of scale would
be realized as the Fund Complex grows; and whether BlackRock realizes other
benefits from its relationship with the Fund.

A. Nature, Extent and Quality of the Services: In evaluating the nature, extent
and quality of the Advisors' services, the Board reviewed information concerning
the types of services that the Advisors provide and are expected to provide to
the Fund, narrative and statistical information concerning the Fund's
performance record and how such performance compares to the Fund's Peers,
information describing BlackRock's organization and its various departments, the
experience and responsibilities of key personnel and available resources. The
Board noted the willingness of the personnel of BlackRock to engage in open,
candid discussions with the Board. The Board further considered the quality of
the Advisors' investment process in making portfolio management decisions.

In addition to advisory services, the Directors considered the quality of the
administrative or non-investment advisory services provided to the Fund. In this
regard, the Advisors and their affiliates provided the Fund with such
administrative, transfer agency, shareholder and other services, as applicable
(exclusive of, and in addition to, any such services provided by others for the
Fund), and officers and other personnel as are necessary for the operations of
the Fund. In addition to investment management services, the Advisors and their
affiliates provided the Fund with services such as: preparing shareholder
reports and communications, including annual and semi-annual financial
statements and Fund websites; communications with analysts to support secondary
market trading; assisting with daily accounting and pricing; preparing periodic
filings with regulators and stock exchanges; overseeing and coordinating the
activities of other service providers; administering and organizing Board
meetings and preparing the Board materials for such meetings; providing legal
and compliance support (such as helping to prepare proxy statements and
responding to regulatory inquiries); and performing other Fund administrative
tasks necessary for the operation of the Fund (such as tax reporting and
fulfilling regulatory filing requirements). The Board considered the Advisors'
policies and procedures for assuring compliance with applicable laws and
regulations.

B. The Investment Performance of the Fund and BlackRock: As previously noted,
the Board received performance information regarding the Fund and its Peers.
Among other things, the Board received materials reflecting the Fund's historic
performance and the Fund's performance compared to its Peers. More specifically,
the Fund's one-, three- and five-year total returns (when applicable) were
evaluated relative to its respective Peers (including the Peers' median
performance).

The Board reviewed a narrative analysis of the Peer rankings prepared by Lipper
and summarized by BlackRock at the Board's request. The summary placed the Peer
rankings into context by analyzing various factors that affect these
comparisons.

The Board noted that in general the Fund performed better than its Peers in that
its performance was at or above the median in at least two for the one-, three-
and five-year periods reported.

After considering this information, the Boards concluded that the performance of
the Fund, in light of and after considering the other facts and circumstances
applicable to the Fund, supports a conclusion that the Fund's Agreements should
be renewed.

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: In evaluating the management fees and expenses that a Fund is expected to
bear, the Board considered the Fund's current management fee structure and the
Fund's expense ratios in absolute terms as well as relative to the fees and
expense ratios of its applicable Peers. The Board, among other things, reviewed
comparisons of the Fund's gross management fees before and after any applicable
reimbursements and fee waivers and total expense ratios before and after any
applicable waivers with those of its applicable Peers. The Board also reviewed a
narrative analysis of the Peer rankings prepared by Lipper and summarized by
BlackRock at the request of the Board. This summary placed the Peer rankings
into context by analyzing various factors that affect these comparisons.

================================================================================

Disclosure of Investment Advisory Agreement and Subadvisory Agreement
(continued)

The Board noted that the Fund paid contractual management fees lower than or
equal to the median contractual fees paid by its Peers. This comparison was made
without giving effect to any expense reimbursements or fee waivers.

The Board also compared the management fees charged and services provided to the
closed-end investment companies managed by the Advisors to the management fees
charged by the Advisors to other types of clients (such as open-end investment
companies and separately managed institutional accounts) in similar investment
categories. The Board noted certain differences in services provided and costs
incurred by the Advisors with respect to closed-end funds compared to separately
managed accounts and open-end funds in general and the reasons for such
differences.

In connection with the Board's consideration of the fees and expense
information, the Board reviewed the considerable investment management
experience of the Advisors and considered the high level of investment
management, administrative and other services provided by the Advisors. In light
of these factors and the other facts and circumstances applicable to the Fund,
the Board concluded that the fees paid and level of expenses incurred by the
Fund under its Agreements support a conclusion that the Fund's Agreements should
be renewed.

D. Profitability of BlackRock: The Board also considered BlackRock's
profitability in conjunction with its review of fees. The Board reviewed
BlackRock's profitability with respect to the Fund Complex and other fund
complexes managed by the Advisors. In reviewing profitability, the Board
recognized that one of the most difficult issues in determining profitability is
establishing a method of allocating expenses. The Board also reviewed
BlackRock's assumptions and methodology of allocating expenses, noting the
inherent limitations in allocating costs among various advisory products. The
Board also recognized that individual fund or product line profitability of
other advisors is generally not publicly available.

The Board recognized that profitability may be affected by numerous factors
including, among other things, the types of funds managed, expense allocations
and business mix, and therefore comparability of profitability is somewhat
limited. Nevertheless, to the extent available, the Board considered BlackRock's
operating margin compared to the operating margin estimated by BlackRock for a
leading investment management firm whose operations consist primarily of
advising closed-end funds. The comparison indicated that BlackRock's operating
margin was approximately the same as the operating margin of such firm.

In evaluating the reasonableness of the Advisors' compensation, the Board also
considered any other revenues paid to the Advisors, including partial
reimbursements paid to the Advisors for certain non-investment advisory
services, if applicable. The Board noted that these payments were less than the
Advisors' costs for providing these services. The Board also considered indirect
benefits (such as soft dollar arrangements) that the Advisors and their
affiliates are expected to receive, which are attributable to their management
of the Fund.

The Board concluded that BlackRock's profitability, in light of all the other
facts and circumstances applicable to the Fund, supports a conclusion that the
Fund's Agreements should be renewed.

E. Economies of Scale: In reviewing the Fund's fees and expenses, the Board
examined the potential benefits of economies of scale, and whether any economies
of scale should be reflected in the Fund's fee structure, for example through
the use of breakpoints for the Fund or the Fund Complex. In this regard, the
Board reviewed information provided by BlackRock, noting that most closed-end
fund complexes do not have fund-level breakpoints because closed-end funds
generally do not experience substantial growth after their initial public
offering and each fund is managed independently consistent with its own
investment objectives. The Board noted that only three closed-end funds in the
Fund Complex have breakpoints in their respective fee structures. Information
provided by Lipper also revealed that only one closed-end fund complex used a
complex-level breakpoint structure.

================================================================================

Disclosure of Investment Advisory Agreement and Subadvisory Agreement
(concluded)

F. Other Factors: In evaluating fees, the Board also considered indirect
benefits or profits the Advisors or their affiliates may receive as a result of
their relationships with the Fund ("fall-out benefits"). The Directors,
including the Independent Directors, considered the intangible benefits that
accrue to the Advisors and their affiliates by virtue of their relationships
with the Fund, including potential benefits accruing to the Advisors and their
affiliates as a result of participating in offerings of the Fund's shares,
potentially stronger relationships with members of the broker-dealer community,
increased name recognition of the Advisors and their affiliates, enhanced sales
of other investment funds and products sponsored by the Advisors and their
affiliates and increased assets under management which may increase the benefits
realized by the Advisors from soft dollar arrangements with broker-dealers. The
Board also considered the unquantifiable nature of these potential benefits.

II. Conclusion with Respect to the Agreements

In reviewing the Agreements, the Directors did not identify any single factor
discussed above as all-important or controlling and different Directors may have
attributed different weights to the various factors considered. The Directors,
including the Independent Directors, unanimously determined that each of the
factors described above, in light of all the other factors and all of the facts
and circumstances applicable to the Fund, was acceptable for the Fund and
supported the Directors' conclusion that the terms of each Agreement were fair
and reasonable, that the Fund's fees are reasonable in light of the services
provided to the Fund and that each Agreement should be approved.

================================================================================

Automatic Dividend Reinvestment Plan

How the Plan Works -- The Fund offers a Dividend Reinvestment Plan (the "Plan")
under which income and capital gains dividends paid by a Fund are automatically
reinvested in additional shares of Common Stock of the Fund. The Plan is
administered on behalf of the shareholders by Computershare Trust Company, N.A.
(the "Plan Agent"). Under the Plan, whenever the Fund declares a dividend,
participants in the Plan will receive the equivalent in shares of Common Stock
of the Fund. The Plan Agent will acquire the shares for the participant's
account either (i) through receipt of additional unissued but authorized shares
of the Fund's ("newly issued shares") or (ii) by purchase of outstanding shares
of Common Stock on the open market on the New York Stock Exchange or elsewhere.
If, on the dividend payment date, the Fund's net asset value per share is equal
to or less than the market price per share plus estimated brokerage commissions
(a condition often referred to as a "market premium"), the Plan Agent will
invest the dividend amount in newly issued shares. If the Fund's net asset value
per share is greater than the market price per share (a condition often referred
to as a "market discount"), the Plan Agent will invest the dividend amount by
purchasing on the open market additional shares. If the Plan Agent is unable to
invest the full dividend amount in open market purchases, or if the market
discount shifts to a market premium during the purchase period, the Plan Agent
will invest any uninvested portion in newly issued shares. The shares acquired
are credited to each shareholder's account. The amount credited is determined by
dividing the dollar amount of the dividend by either (i) when the shares are
newly issued, the net asset value per share on the date the shares are issued or
(ii) when shares are purchased in the open market, the average purchase price
per share.

Participation in the Plan -- Participation in the Plan is automatic, that is, a
shareholder is automatically enrolled in the Plan when he or she purchases
shares of Common Stock of the Fund unless the shareholder specifically elects
not to participate in the Plan. Shareholders who elect not to participate will
receive all dividend distributions in cash. Shareholders who do not wish to
participate in the Plan must advise the Plan Agent in writing (at the address
set forth below) that they elect not to participate in the Plan. Participation
in the Plan is completely voluntary and may be terminated or resumed at any time
without penalty by writing to the Plan Agent.

Benefits of the Plan -- The Plan provides an easy, convenient way for
shareholders to make additional, regular investments in the Fund. The Plan
promotes a long-term strategy of investing at a lower cost. All shares acquired
pursuant to the Plan receive voting rights. In addition, if the market price
plus commissions of a Fund's shares is above the net asset value, participants
in the Plan will receive shares of the Fund for less than they could otherwise
purchase them and with a cash value greater than the value of any cash
distribution they would have received. However, there may not be enough shares
available in the market to make distributions in shares at prices below the net
asset value. Also, since the Fund does not redeem shares, the price on resale
may be more or less than the net asset value.

Plan Fees -- There are no enrollment fees or brokerage fees for participating in
the Plan. The Plan Agent's service fees for handling the reinvestment of
distributions are paid for by the Fund. However, brokerage commissions may be
incurred when the Fund purchases shares on the open market and shareholders will
pay a pro rata share of any such commissions.

Tax Implications -- The automatic reinvestment of dividends and distributions
will not relieve participants of any federal, state or local income tax that may
be payable (or required to be withheld) on such dividends. Therefore, income and
capital gains may still be realized even though shareholders do not receive
cash. The value of shares acquired pursuant to the Plan will generally be
excluded from gross income to the extent that the cash amount reinvested would
be excluded from gross income. If, when the Fund's shares are trading at a
market premium, the Fund issues shares pursuant to the Plan that have a greater
fair market value than the amount of cash reinvested, it is possible that all or
a portion of the discount from the market value (which may not exceed 5% of the
fair market value of the Fund's shares) could be viewed as a taxable
distribution. If the discount is viewed as a taxable distribution, it is also
possible that the taxable character of this discount would be allocable to all
the shareholders, including shareholders who do not participate in the Plan.
Thus, shareholders who do not participate in the Plan might be required to
report as ordinary income a portion of their distributions equal to their
allocable share of the discount.

Contact Information -- All correspondence concerning the Plan, including any
questions about the Plan, should be directed to the Plan Agent at Computershare
Trust Company, N.A., P.O. Box 43010, Providence, RI 02940-3010, Telephone: (800)
426-5523.

(1)   Directors serve until their resignation, removal or death, or until
      December 31 of the year in which they turn 72.

(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 Fund'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: G. Nicholas Beckwith, III since
      1999; Richard E. Cavanagh since 1994; Kent Dixon since 1988; Frank J.
      Fabozzi since 1988; Kathleen F. Feldstein since 2005; James T. Flynn since
      1996; Jerrold B. Harris since 1999; R. Glenn Hubbard since 2004; W. Carl
      Kester since 1998; Karen P. Robards since 1998 and Robert S. Salomon, Jr.

--------------------------------------------------------------------------------
General Information
--------------------------------------------------------------------------------

The Fund does not make available copies of its Statements of Additional
Information because the Fund's shares are not continuously offered, which means
that the Statement of Additional Information of the Fund has not been updated
after completion of the Fund's offering and the information contained in the
Fund's Statement of Additional Information may have become outdated.

During the period, there were no material changes in the Fund's investment
objective or policies or to the Fund's charter or by-laws that were not approved
by the shareholders or in the principal risk factors associated with investment
in the Fund. There have been no changes in the persons who are primarily
responsible for the day-to-day management of the Fund's portfolio.

The Fund will mail only one copy of shareholder documents, including annual and
semi-annual reports and proxy statements, to shareholders with multiple accounts
at the same address. This practice is commonly called "householding" and it is
intended to reduce expenses and eliminate duplicate mailings of shareholder
documents. Mailings of your shareholder documents may be householded
indefinitely unless you instruct us otherwise. If you do not want the mailing of
these documents to be combined with those for other members of your household,
please contact the Fund at (800) 441-7762.

Quarterly performance, semi-annual and annual reports and other information
regarding the Fund may be found on BlackRock's website, which can be accessed at
http://www.blackrock.com. This reference to BlackRock's website is intended to
allow investors public access to information regarding the Fund and does not,
and is not intended to, incorporate BlackRock's website into this report.

BlackRock is committed to maintaining the privacy of its current and former fund
investors and individual clients (collectively, "Clients") and to safeguarding
their non-public personal information. The following information is provided to

specific laws, rules or regulations.

BlackRock obtains or verifies personal non-public information from and about you
from different sources, including the following: (i) information we receive from
you or, if applicable, your financial intermediary, on applications, forms or
other documents; (ii) information about your transactions with us, our

--------------------------------------------------------------------------------
Proxy Voting Policy
--------------------------------------------------------------------------------

The Board of Directors of the Fund has delegated the voting of proxies for Fund
securities to the Investment Adviser pursuant to the Investment Adviser's proxy
voting guidelines. Under these guidelines, the Investment Adviser will vote
proxies related to Fund securities in the best interests of the Fund and its
stockholders. From time to time, a vote may present a conflict between the
interests of the Fund's stockholders, on the one hand, and those of the
Investment Adviser, or any affiliated person of the Fund or the Investment
Adviser, on the other. In such event, provided that the Investment Adviser's
Equity Investment Policy Oversight Committee, or a sub-committee thereof (the
"Committee") is aware of the real or potential conflict or material non-routine
matter and if the Committee does not reasonably believe it is able to follow its
general voting guidelines (or if the particular proxy matter is not addressed in
the guidelines) and vote impartially, the Committee may retain an independent
fiduciary to advise the Committee on how to vote or to cast votes on behalf of
the Investment Adviser's clients. If the Investment Adviser determines not to
retain an independent fiduciary, or does not desire to follow the advice of such

Item 2 -   Code of Ethics - The registrant (or the "Fund") has adopted a
           code of ethics, as of the end of the period covered by this report,
           applicable to the registrant's principal executive officer, principal
           financial officer and principal accounting officer, or persons
           performing similar functions. During the period covered by this
           report, there have been no amendments to or waivers granted under the

Item 3 -   Audit Committee Financial Expert - The registrant's board of
           directors or trustees, as applicable (the "board of directors") has
           determined that (i) the registrant has the following audit committee
           financial experts serving on its audit committee and (ii) each audit
           committee financial expert is independent:
           Kent Dixon (term began effective November 1, 2007)
           Frank J. Fabozzi (term began effective November 1, 2007)
           James T. Flynn (term began effective November 1, 2007)
           Joe Grills (term ended effective November 1, 2007)
           W. Carl Kester (term began effective November 1, 2007)
           Karen P. Robards (term began effective November 1, 2007)
           Robert S. Salomon, Jr.

           The registrant's board of directors has determined that W. Carl
           Kester and Karen P. Robards qualify as financial experts pursuant to
           Item 3(c)(4) of Form N-CSR.

           Prof. Kester has a thorough understanding of generally accepted
           accounting principles, financial statements and internal control over
           financial reporting as well as audit committee functions. Prof.
           Kester has been involved in providing valuation and other financial
           consulting services to corporate clients since 1978. Prof. Kester's
           financial consulting services present a breadth and level of
           complexity of accounting issues that are generally comparable to the
           breadth and complexity of issues that can reasonably be expected to
           be raised by the registrant's financial statements.

           Ms. Robards has a thorough understanding of generally accepted
           accounting principles, financial statements and internal control over
           financial reporting as well as audit committee functions. Ms. Robards
           has been President of Robards & Company, a financial advisory firm,
           since 1987. Ms. Robards was formerly an investment banker for more
           than 10 years where she was responsible for evaluating and assessing
           the performance of companies based on their financial results. Ms.
           Robards has over 30 years of experience analyzing financial
           statements. She also is a member of the audit committee of one
           publicly held company and a non-profit organization.

           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.

           (iv) Potential Material Conflicts of Interest



           BlackRock, Inc. and its affiliates (collectively, herein "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
           or 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 regard, it
           should be noted that each portfolio manager currently manages certain
           accounts that are subject to performance fees. In addition, Mr.
           Keenan assists 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 May 31, 2008:

           Portfolio Manager Compensation Overview

           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 performance-based
           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. Senior portfolio managers who perform additional management
           functions within the portfolio management group or within BlackRock
           may receive additional compensation for serving in these other
           capacities.

           Discretionary Incentive Compensation
           Discretionary incentive compensation 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, of the firm's assets
           under management or supervision by that portfolio manager relative to
           predetermined benchmarks, and the individual's seniority, role within
           the portfolio management team, teamwork and contribution to the
           overall performance of these portfolios and BlackRock. In most cases,
           including for the portfolio managers of the Fund, these benchmarks
           are the same as the benchmark or benchmarks against which the
           performance of the Fund or other accounts managed by the portfolio
           managers are measured. BlackRock's Chief Investment Officers
           determine the benchmarks against which the performance of funds and
           other accounts managed by each portfolio manager is compared and the
           period of time over which performance is evaluated. With respect to
           the portfolio managers, such benchmarks for the Fund include the
           following:

           Portfolio Manager           Benchmarks Applicable to Each Manager

           Kevin Booth                A combination of market-based indices (e.g., The Lehman Brothers U.S. Corporate
                                      High Yield 2% Issuer Cap Index), certain customized indices and certain fund industry
                                      peer groups.
           -------------------------------------------------------------------------------------------------------------------

                                      High Yield 2% Issuer Cap Index), certain customized indices and certain fund industry
                                      peer groups.
           -------------------------------------------------------------------------------------------------------------------
           James Keenan               A combination of market-based indices (e.g., The Lehman Brothers U.S. Corporate
                                      High Yield 2% Issuer Cap Index), certain customized indices and certain fund industry
                                      peer groups.
           -------------------------------------------------------------------------------------------------------------------


           BlackRock's Chief Investment Officers make a subjective determination
           with respect to the portfolio managers' compensation based on the
           performance of the funds and other accounts managed by each portfolio
           manager relative to the various benchmarks noted above. Performance
           is measured on both a pre-tax and after-tax basis over various time
           periods including 1, 3, 5 and 10-year periods, as applicable.

           Distribution of Discretionary Incentive Compensation
           Discretionary incentive compensation is distributed to portfolio
           managers in a combination of cash and BlackRock, Inc. restricted
           stock units which vest ratably over a number of years. The BlackRock,
           Inc. restricted stock units, if properly vested, will be settled in
           BlackRock, Inc. common stock. Typically, the cash bonus, when
           combined with base salary, represents more than 60% of total
           compensation for the portfolio managers. Paying a portion of annual
           bonuses in stock puts compensation earned by a portfolio



           manager for a given year "at risk" based on the BlackRock's ability
           to sustain and improve its performance over future periods.

                     Long-Term Retention and Incentive Plan ("LTIP") --The LTIP
           is a long-term incentive plan that seeks to reward certain key
           employees. Prior to 2006, the plan provided for the grant of awards
           that were 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. Beginning in
           2006, awards are granted under the LTIP in the form of BlackRock,
           Inc. restricted stock units that, if properly vested and subject to
           the attainment of certain performance goals, will be settled in
           BlackRock, Inc. common stock. Each portfolio manager has received
           awards under the LTIP.

                     Deferred Compensation Program --A portion of the
           compensation paid to eligible BlackRock employees may be voluntarily
           deferred into an account that tracks the performance of certain of
           the firm's investment products. Each participant in the deferred
           compensation program is permitted to allocate his deferred amounts
           among the various investment options. Each portfolio manager has
           participated in the deferred compensation program.

           Other compensation benefits. In addition to base compensation and
           discretionary incentive compensation, portfolio managers may be
           eligible to receive or participate in one or more of the following:

                     Incentive Savings Plans -- BlackRock, Inc. has created a
           variety of incentive savings plans in which BlackRock employees are
           eligible to participate, including a 401(k) plan, the BlackRock
           Retirement Savings Plan (RSP), and the BlackRock Employee Stock
           Purchase Plan (ESPP). The employer contribution components of the RSP
           include a company match equal to 50% of the first 6% of eligible pay
           contributed to the plan capped at $4,000 per year, and a company
           retirement contribution equal to 3% of eligible compensation, plus an
           additional contribution of 2% for any year in which BlackRock has
           positive net operating income. The RSP offers a range of investment
           options, including registered investment companies managed by the
           firm. BlackRock contributions follow the investment direction set by
           participants for their own contributions or, absent employee
           investment direction, are invested into a balanced portfolio. The
           ESPP allows for investment in BlackRock common stock at a 5% discount
           on the fair market value of the stock on the purchase date. Annual
           participation in the ESPP is limited to the purchase of 1,000 shares
           or a dollar value of $25,000. Each portfolio manager is eligible to
           participate in these plans.

          (a)(4)  Beneficial Ownership of Securities. As of May 31, 2008, Mr.
                  Gary did not beneficially own any stock issued by the Fund. As
                  of May 31, 2008, Mr. Booth beneficially owned stock issued by
                  the Fund in the range of $10,001-$50,000. As of May 31, 2008,
                  Mr. Keenan beneficially owned stock issued by the Fund in the
                  range of $10,001-$50,000.
