2 BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2009

Dear Shareholder

The past 12 months reveal two distinct market backdrops — one of extreme investor pessimism and decided weakness, and another of cautious optimism

and nascent signs of recovery. The first half of the period was characterized by the former, as the global financial crisis erupted into the worst recession in

decades. Daily headlines recounted universal macroeconomic deterioration, financial sector casualties, volatile swings in global equity markets, and

unprecedented government intervention that included widespread (and globally coordinated) monetary and quantitative easing by central banks and

large-scale fiscal stimuli. Sentiment improved noticeably in March 2009, however, on the back of new program announcements by the US Treasury

Department and Federal Reserve, as well as generally stronger-than-expected economic data in a few key areas, including retail sales, business and

consumer confidence, manufacturing and housing.

In this environment, US equities contended with extraordinary volatility, posting steep declines through mid-March 2009 before going on a three-month

rally that largely negated year-to-date losses. Late in the period, investor enthusiasm waned and a correction ensued for several weeks, mostly as a result

of profit taking and portfolio rebalancing, as opposed to a change in the economic outlook. Equities rallied once again as the period drew to a close,

resulting in positive year-to-date returns for all major indexes. The experience in international markets was similar to that in the United States, though

performance was generally more extreme both on the decline and on the upturn. Notably, emerging markets, which lagged most developed regions

through the downturn, reassumed leadership in 2009 as these areas of the globe have generally seen a stronger acceleration in economic recovery.

In fixed income markets, while the flight to quality remained a prevalent theme, relatively attractive yields and distressed valuations, alongside a more favor-

able macro environment, eventually captured investor attention, leading to a sharp recovery in non-Treasury assets. This has been particularly evident in the

high yield sector, which has firmly outpaced all other taxable asset classes since the start of 2009. At the same time, the municipal bond market enjoyed a

strong return after the exceptional market volatility of 2008, buoyed by a combination of attractive valuations, robust retail investor demand and a slowdown in

forced selling. Direct aid to state and local governments via the American Recovery and Reinvestment Act of 2009 has also lent support to municipal bonds.

The market environment has clearly improved since the beginning of the year, but a great deal of uncertainty and risk remain. Through periods of market

turbulence, as ever, BlackRock’s full resources are dedicated to the management of our clients’ assets. For additional insight and timely “food for thought,”

we invite you to visit our award-winning Shareholder® magazine, now available exclusively online at www.blackrock.com/shareholdermagazine. We thank

you for entrusting BlackRock with your investments, and we look forward to continuing to serve you in the months and years ahead.

Announcement to Shareholders

On June 16, 2009, BlackRock, Inc. announced that it received written notice from Barclays PLC (“Barclays”) in which Barclays’ Board of Directors had

accepted BlackRock’s offer to acquire Barclays Global Investors (“BGI”). At a special meeting held on August 6, 2009, BlackRock’s proposed purchase of

BGI was approved by an overwhelming majority of Barclays’ voting shareholders, an important step toward closing the transaction. The combination of

BlackRock and BGI will bring together market leaders in active and index strategies to create the preeminent asset management firm. The transaction is

scheduled to be completed in the fourth quarter of 2009, subject to important fund shareholder and regulatory approvals.

Fund Summary as of July 31, 2009

Portfolio Management Commentary

How did the Fund perform?

The Fund underperformed the benchmark S&P MidCap 400 Index and
the S&P MidCap 400/Citigroup Value Index for the six-month period.

What factors influenced performance?

Underperformance over the past six months stemmed primarily from
weakness in the materials and utilities sectors. Within materials, disap-
pointing stock selection among metals & mining names overshadowed
the positive effects of an overweight in the sub-sector. The Fund was
underexposed to stocks of the lowest quality and highest beta, which
led the sub-sector up nearly 70%. Underperformance in utilities can
be attributed largely to an overweight in multi-utilities, as the defensive
sub-sector lagged overall benchmark performance by roughly 20%.

The Fund’s relatively high average cash position during the period (7%)
significantly detracted from performance during the market rally, subtract-
ing more than 200 basis points from relative returns. Cash is a residual
of the investment process, and we would expect the position to fall back
below 5% as market conditions stabilize.

On the positive side, Fund performance benefited from strength in the
health care, energy and consumer discretionary sectors. In health care,
positive relative performance was driven primarily by stock selection in
the biotechnology and health care equipment & supplies sub-sectors.

In energy, although performance within the energy equipment & services
sub-sector lagged the benchmark, an overweight to and selection among
oil, gas & consumable fuels names drove relative strength within the
sector. Key contributors included Cabot Oil & Gas Corp. and Newfield
Exploration Co., both of which jumped more than 70% during the period.
In consumer discretionary, an underweight in diversified consumer services
stocks boosted relative returns.

Describe recent portfolio activity.

• During the six-month period, we increased the Fund’s exposure to health
care, adding positions in both the health care equipment & supplies and
health care providers & services sub-sectors. We also added to the Fund’s
weighting in consumer discretionary, with the largest additions in the tex-
tiles, apparel & luxury goods and specialty retail sub-sectors.

Describe Fund positioning at period end.

• The Fund ended the period with an overweight relative to the benchmark
in information technology (primarily among software companies), and
underweights in consumer discretionary (particularly within the hotels,
restaurants & leisure; diversified consumer services; and household
durables sub-sectors), financials (notably among commercial real estate
investment trusts and capital markets firms), industrials (primarily in elec-
trical equipment and professional services) and materials (particularly
chemicals).

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.

About Fund Performance

• Institutional Shares are not subject to any sales charge. Institutional
Shares bear no ongoing distribution or service fees and are available only
to eligible investors.

• Investor A Shares incur a maximum initial sales charge (front-end load)
of 5.25% and a service fee of 0.25% per year (but no distribution fee).

• Investor B Shares are subject to a maximum contingent deferred sales
charge of 4.50% declining to 0% after six years. In addition, Investor B
Shares are subject to a distribution fee of 0.75% per year and a service
fee of 0.25% per year. These shares automatically convert to Investor A
Shares after approximately eight years. (There is no initial sales charge
for automatic share conversions.) All returns for periods greater than
eight years reflect this conversion. Investor B Shares of the Fund are
no longer available for purchase except through exchanges, dividend
reinvestments, and for purchase by certain qualified employee
benefit plans.

• Investor C Shares are subject to a 1.00% contingent deferred sales
charge if redeemed within one year of purchase. These shares are subject
to a distribution fee of 0.75% and a service fee of 0.25% per year.

• Class R Shares do not incur a maximum initial sales charge (front-end
load) or deferred sales charge. These shares are subject to a distribution
fee of 0.25% per year and a service fee of 0.25% per year. Class R
Shares are available only to certain retirement plans. Prior to February
4, 2003, Class R Share performance results are those of Institutional
Shares (which have no distribution or service fees) restated to reflect
Class R Share fees.

Performance information reflects past performance and does not guar-
antee future results. Current performance may be lower or higher than the
performance data quoted. Refer to www.blackrock.com/funds to obtain
performance data current to the most recent month-end. Performance
results do not reflect the deduction of taxes that a shareholder would
pay on fund distributions or the redemption of fund shares. Figures
shown in the performance table on the previous page assume reinvest-
ment of all dividends and capital gain distributions, if any, at net asset
value on the ex-dividend date. Investment return and principal value of
shares will fluctuate so that shares, when redeemed, may be worth more
or less than their original cost. Dividends paid to each class of shares will
vary because of the different levels of service, distribution and transfer
agency fees applicable to each class, which are deducted from the
income available to be paid to shareholders.

Disclosure of Expenses

Shareholders of the Fund may incur the following charges: (a) expenses
related to transactions, including sales charges, redemption fees and
exchange fees; and (b) operating expenses including advisory fees, distri-
bution fees including 12b-1 fees, and other Fund expenses. The expense
example on the previous page (which is based on a hypothetical invest-
ment of $1,000 invested on February 1, 2009 and held through July 31,
2009) is intended to assist shareholders both in calculating expenses
based on an investment in the Fund and in comparing these expenses
with similar costs of investing in other mutual funds.

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

The table also provides information about hypothetical account values
and hypothetical expenses based on the Fund’s actual expense ratio and
an assumed rate of return of 5% per year before expenses. In order to
assist shareholders in comparing the ongoing expenses of investing in this
Fund and other funds, compare the 5% hypothetical example with the 5%
hypothetical examples that appear in other funds’ shareholder reports.

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

	recognized market indexes or ratings group indexes, and/or as defined by Fund
	management. This definition may not apply for purposes of this report, which
	may combine industry sub-classifications for reporting ease.

• Financial Accounting Standards Board Statement of Financial Accounting
Standards No. 157, “Fair Value Measurements” clarifies the definition of fair
value, establishes a framework for measuring fair values and requires additional
disclosures about the use of fair value measurements. Various inputs are used
in determining the fair value of investments, which are as follows:
• Level 1 — price quotations in active markets/exchanges for identical securities
• Level 2 — other observable inputs (including, but not limited to: quoted prices
for similar assets or liabilities in markets that are active, quoted prices for
identical or similar assets or liabilities in markets that are not active, inputs
other than quoted prices that are observable for the assets or liabilities (such
as interest rates, yield curves, volatilities, prepayment speeds, loss severities,
credit risks and default rates) or other market-corroborated inputs)
• Level 3 — unobservable inputs based on the best information available in the
circumstances, to the extent observable inputs are not available (including the
Fund's own assumptions used in determining the fair value of investments)
The inputs or methodology used for valuing securities are not necessarily an in-
dication of the risk associated with investing in those securities. For information
about the Fund’s policy regarding valuation of investments and other significant
accounting policies, please refer to Note 1 of the Notes to Financial Statements.
The following table summarizes the inputs used as of July 31, 2009 in determin-
ing the fair valuation of the Fund’s investments:

Notes to Financial Statements (Unaudited)

1. Organization and Significant Accounting Policies:

BlackRock Mid Cap Value Opportunities Fund (the “Fund”) of BlackRock
Mid Cap Value Opportunities Series, Inc. (the “Series”) is registered under
the Investment Company Act of 1940, as amended (the “1940 Act”), as
a diversified, open-end management investment company and is organ-
ized as a Maryland corporation. The Fund’s financial statements are pre-
pared 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 offers multiple classes of shares. Institutional Shares are sold
without a sales charge and only to certain eligible investors. Investor A
Shares are generally sold with a front-end sales charge. Shares of
Investor B and Investor C may be subject to a contingent deferred sales
charge. Class R Shares are generally sold only to certain retirement or
similar plans. All classes of shares have identical voting, dividend, liqui-
dation and other rights and the same terms and conditions, except
that Investor A, Investor B, Investor C and Class R Shares bear certain
expenses related to the shareholder servicing of such shares, and
Investor B, Investor C and Class R Shares also bear certain expenses
related to the distribution of such shares. Investor B Shares automati-
cally convert to Investor A Shares after approximately eight years.
Each class has exclusive voting rights with respect to matters relating
to its shareholder servicing and distribution expenditures (except that
Investor B shareholders may vote on material changes to the Investor A
distribution plan).

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

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

In the event that application of these methods of valuation results in
a price for an investment which is deemed not to be representative of
the market value of such investment, the investment will be valued by
a method approved by the Board of Directors (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 deter-
minations shall be based upon all available factors that the investment
advisor and/or sub-advisor deems relevant. The pricing of all Fair Value
Assets is subsequently reported to the Board or a committee thereof.

Investment Transactions and Investment Income: For financial reporting
purposes, investment transactions are recorded on the dates the trans-
actions are entered into (the trade dates). Realized gains and losses on
investment 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 sub-
sequently recorded when the Fund has determined the ex-dividend date.
Upon notification from issuers, some of the dividend income received
from a real estate investment trust may be redesignated as a reduction
of cost of the related investment and/or realized gain. Interest income
is recognized on the accrual basis.

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

Securities Lending: The Fund may lend securities to financial institutions
that provide cash 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 deter-
mined at the close of business of the Fund and any additional required
collateral is delivered to the Fund on the next business day. The Fund
typically receives the income on the loaned securities but does not
receive the income on the collateral. The Fund may invest the cash col-
lateral 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 the standard time period for settlement of securities
transactions. The Fund may pay reasonable lending agent, administrative
and custodial fees in connection with its loans. In the event that the bor-
rower 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 if the value of an investment purchased with cash collateral falls
below the market value of the loaned securities, or if the value of an
investment purchased with cash collateral falls below the value of the
original cash collateral received.

Income Taxes: It is the Fund’s policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment compa-
nies and to distribute substantially all of its taxable income to its share-
holders. Therefore, no federal income tax provision is required. Under the
applicable foreign tax laws, a withholding tax may be imposed on inter-
est, dividends and capital gains at various rates.

Notes to Financial Statements (continued)

The Fund files US federal and various state and local tax returns. No
income tax returns are currently under examination. The statutes of
limitations on the Fund’s US federal tax returns remain open for each
of the four years ended January 31, 2009. 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 Pronouncement: In June 2009, Statement of
Financial Accounting Standards No. 166, “Accounting for Transfers of
Financial Assets — an amendment of FASB Statement No. 140” (“FAS
166”), was issued. FAS 166 is intended to improve the relevance, repre-
sentational faithfulness and comparability of the information that a
reporting entity provides in its financial statements about a transfer of
financial assets; the effects of a transfer on its financial position, finan-
cial performance, and cash flows; and a transferor’s continuing involve-
ment, if any, in transferred financial assets. FAS 166 is effective for
financial statements issued for fiscal years and interim periods begin-
ning after November 15, 2009. Earlier application is prohibited. The
recognition and measurement provisions of FAS 166 must be applied to
transfers occurring on or after the effective date. Additionally, the disclo-
sure provisions of FAS 166 should be applied to transfers that occurred
both before and after the effective date of FAS 166. The impact of FAS
166 on the Fund’s financial statement disclosures, if any, is currently
being assessed.

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

2. Investment Advisory Agreement and Other Transactions
with Affiliates:

The PNC Financial Services Group, Inc. (“PNC”) and Bank of America
Corporation (“BAC”) are the largest stockholders of BlackRock, Inc.
(“BlackRock”). Due to the ownership structure, PNC is an affiliate for
1940 Act purposes, but BAC is not.

The Series, on behalf of the Fund, entered into an Investment Advisory
Agreement with BlackRock Advisors, LLC (the “Manager”), the Fund’s
investment advisor, an indirect, wholly owned subsidiary of BlackRock,
to provide investment advisory and administration services.

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 operation of the Fund. For such services,
the Fund pays the Manager a monthly fee at an annual rate of 0.65% of
the average daily value of the Fund’s net assets.

The Manager has agreed to waive its advisory fee by the amount
of investment advisory fees the Fund pays to the Manager indirectly

through its investment in affiliated money market funds. This amount
is shown as fees waived by advisor in the Statement of Operations.

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

For the six months ended July 31, 2009, the Series, on behalf of the
Fund, reimbursed the Manager $2,118 for certain accounting services,
which is included in accounting services in the Statement of Operations.

The Fund has entered into a Distribution Agreement and Distribution
Plans with BlackRock Investments, LLC (“BRIL”), which is an affiliate
of BlackRock.

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

	Service	Distribution
	Fee	Fee
Investor A	0.25%	—
Investor B	0.25%	0.75%
Investor C	0.25%	0.75%
Class R	0.25%	0.25%

Pursuant to sub-agreements with BRIL, broker-dealers and BRIL provide
shareholder servicing and distribution services to the Fund. The ongoing
service fee and/or distribution fee compensates BRIL and each broker-
dealer for providing shareholder servicing and/or distribution-related
services to Investor A, Investor B, Investor C and Class R shareholders.

For the six months ended July 31, 2009, affiliates earned underwriting
discounts, direct commissions and dealer concessions on sales of the
Fund’s Investor A Shares, which totaled $73. Affiliates received contin-
gent deferred sales charges of $5,991, and $1,510 relating to trans-
actions in Investor B and Investor C Shares, respectively. Furthermore,
affiliates received contingent deferred sales charges of $5 relating
to transactions subject to front-end sales charge waivers on Investor
A Shares.

The Fund has received an exemptive order from the Securities and
Exchange Commission permitting it, among other things, to pay an affili-
ated securities lending agent a fee based on a share of the income
derived from the securities lending activities. The Fund has retained BIM
as the securities lending agent for a fee based on a share of the income
from investment of cash collateral. BIM may, on behalf of the Fund,

BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2009 19

Notes to Financial Statements (continued)

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.
The share of income earned by the Fund on such investments is shown
as securities lending — affiliated in the Statement of Operations. For the
six months ended July 31, 2009, BIM received $19,332 in securities
lending agent fees.

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

The Manager maintains a call center, which is responsible for providing
certain shareholder services to the Fund, such as responding to share-
holder inquiries and processing transactions based upon instructions
from shareholders with respect to the subscription and redemption of
Fund shares. For the six months ended July 31, 2009, the Fund reim-
bursed the Manager for costs incurred running the call center, which are
included in transfer agent in the Statement of Operations.

	Call Center
	Fees
Institutional	$ 346
Investor A	$2,031
Investor B	$ 709
Investor C	$1,162
Class R	$ 385

Certain officers and/or directors of the Fund are officers and/or directors
of BlackRock or its affiliates. The Fund reimburses the Manager for com-
pensation paid to the Fund’s Chief Compliance Officer.

3. Investments:

Purchases and sales of investments, excluding short-term securities,
for the six months ended July 31, 2009 were $126,039,867 and
$126,039,400, respectively.

4. Short-Term Borrowings:

The Fund along with certain other funds managed by the Manager and
its affiliates, is a party to a $500 million credit agreement with a group
of lenders, which expires in November 2009. The Fund may borrow under
the credit agreement to fund shareholder redemptions and for other
lawful purposes other than for leverage. The Fund may borrow up to the
maximum amount allowable under the Fund’s current Prospectus and
Statement of Additional Information, subject to various other legal, regu-
latory or contractual limits. The Fund paid its pro rata share of a 0.02%
upfront fee on the aggregate commitment amount based on its net
assets. The Fund pays a commitment fee of 0.08% per annum based on
the Fund’s pro rata share of the unused portion of the credit agreement,
which is included in miscellaneous in the Statement of Operations.
Amounts borrowed under the credit agreement bear interest at a rate
equal to the higher of the (a) federal funds effective rate and (b) reserve
adjusted one month LIBOR, plus, in each case, the higher of (i) 1.50%
and (ii) 50% of the CDX Index (as defined in the credit agreement) in
effect from time to time. The Fund did not borrow under the credit agree-
ment during the six months ended July 31, 2009.

5. Capital Loss Carryforward:

As of January 31, 2009, the Fund had a capital loss carryforward of
$32,503,018 available to offset future realized capital gains, which
expires January 31, 2017.

6. Market and Credit Risk:

In the normal course of business, the Fund invests in securities and
enters into transactions where risks exist due to fluctuations in the
market (market risk) or failure of the issuer of a security to meet all its
obligations (credit risk). The value of securities held by the Fund may
decline in response to certain events, including those directly involving
the issuers whose securities are owned by the Fund; conditions affecting
the general economy; overall market changes; local, regional or global
political, social or economic instability; and currency and interest rate
and price fluctuations. Similar to credit risk, the Fund may be exposed to
counterparty risk, or the risk that an entity with which the Fund have
unsettled or open transactions may default. Financial assets, which
potentially expose the Fund to credit and counterparty risks, consist
principally of investments and cash due from counterparties. The extent
of the Fund’s exposure to credit and counterparty risks with respect to
these financial assets is approximated by their value recorded in the
Fund’s Statement of Assets and Liabilities.

BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2009 21

Disclosure of Investment Advisory Agreement and Sub-Advisory Agreement

The Board of Directors (the “Board,” and the members of which
are referred to as “Board Members”) of BlackRock Mid Cap Value
Opportunities Fund (the “Fund”), a series of BlackRock Mid Cap Value
Opportunities Series, Inc. (the “Corporation”), met on May 5, 2009
and June 4 – 5, 2009 to consider the approval of the Fund’s invest-
ment advisory agreement (the “Advisory Agreement”) with BlackRock
Advisors, LLC (the “Manager”), the Fund’s investment advisor. The
Board also considered the approval of the sub-advisory agreement
(the “Sub-Advisory Agreement”) between the Manager and BlackRock
Investment Management, LLC (the “Sub-Advisor”) with respect to the
Fund. The Manager and the Sub-Advisor are referred to herein as
“BlackRock.” For simplicity, the Fund and the Corporation are referred
to herein as the “Fund.” The Advisory Agreement and the Sub-Advisory
Agreement are referred to herein as the “Agreements.”

Activities and Composition of the Board

The Board of the Fund consisted of fifteen individuals, twelve of
whom were not “interested persons” of the Fund as defined in the
Investment Company Act of 1940, as amended (the “1940 Act”) (the
“Independent Board Members”), at the time of the Board’s approval
of the Agreements. The Board Members 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 Board Members have retained independent legal counsel
to assist them in connection with their duties. The Chairman of the
Board is an Independent Board Member. The Board has established
five standing committees: an Audit Committee, a Governance and
Nominating Committee, a Compliance Committee, a Performance
Oversight Committee and an Executive Committee, each of which
is composed of Independent Board Members (except for the
Performance Oversight Committee and the Executive Committee,
which each have one interested Board Member) and is chaired by
Independent Board Members.

The Agreements

Pursuant to the 1940 Act, the Board is required to consider the
continuation of the Agreements on an annual basis. In connection
with this process, the Board assessed, among other things, the nature,
scope and quality of the services provided to the Fund by the person-
nel of BlackRock and its affiliates, including investment management,
administrative services, shareholder services, oversight of fund account-
ing and custody, marketing services and assistance in meeting legal
and regulatory requirements.

Throughout the year, the Board, acting directly and through its com-
mittees, considers at each of its meetings factors that are relevant

to its annual consideration of the renewal of the Agreements, including
the services and support provided by BlackRock to the Fund and its
shareholders. Among the matters the Board considered were: (a) invest-
ment performance for one-, three- and five-year periods, as applicable,
against peer funds, and applicable benchmarks, if any, as well as senior
management and portfolio managers’ analysis of the reasons for any
underperformance against its peers; (b) fees, including advisory, admin-
istration, if applicable, and other amounts paid to BlackRock and its
affiliates by the Fund for services, such as transfer agency, marketing
and distribution, call center and fund accounting; (c) Fund operating
expenses; (d) the resources devoted to and compliance reports relat-
ing 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 policies approved by
the Board; (i) the use of brokerage commissions and execution quality;
(j) BlackRock’s implementation of the Fund’s valuation and liquidity
procedures; and (k) periodic updates on BlackRock’s business.

Board Considerations in Approving the Agreements

The Approval Process: Prior to the May 5, 2009 meeting, the
Board requested and received materials specifically relating to
the Agreements. The Board is engaged in an ongoing process with
BlackRock to continuously review the nature and scope of the infor-
mation provided to better assist its deliberations. The materials pro-
vided in connection with the May meeting included (a) information
independently compiled and prepared by Lipper, Inc. (“Lipper”) on
Fund fees and expenses, and the investment performance of the
Fund as compared with a peer group of funds as determined by
Lipper (collectively, “Peers”); (b) information on the profitability of
the Agreements to BlackRock and a discussion of fall-out benefits to
BlackRock and its affiliates and significant shareholders; (c) a general
analysis provided by BlackRock concerning investment advisory fees
charged to other clients, such as institutional and closed-end funds,
under similar investment mandates, as well as the performance of
such other clients; (d) the impact of economies of scale; (e) a sum-
mary of aggregate amounts paid by the Fund to BlackRock; (f) sales
and redemption data regarding the Fund’s shares; and (g) an internal
comparison of management fees classified by Lipper, if applicable.

At an in-person meeting held on May 5, 2009, the Board reviewed
materials relating to its consideration of the Agreements. As a result of
the discussions that occurred during the May 5, 2009 meeting, the
Board presented BlackRock with questions and requests for additional

22 BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2009

Disclosure of Investment Advisory Agreement and Sub-Advisory Agreement (continued)

information and BlackRock responded to these requests with additional
written information in advance of the June 4 – 5, 2009 Board meeting.

At an in-person meeting held on June 4 – 5, 2009, the Fund’s Board,
including the Independent Board Members, unanimously approved the
continuation of the Advisory Agreement between the Manager and the
Fund and the Sub-Advisory Agreement between the Manager and the
Sub-Advisor with respect to the Fund, each for a one-year term ending
June 30, 2010. The Board considered all factors it believed relevant
with respect to the Fund, including, among other factors: (a) the nature,
extent and quality of the services provided by BlackRock; (b) the invest-
ment performance of the Fund and BlackRock portfolio management;
(c) the advisory fee and the cost of the services and profits to be real-
ized by BlackRock and certain affiliates from the relationship with the
Fund; (d) economies of scale; and (e) other factors.

The Board also considered other matters it deemed important to
the approval process, such as payments made to BlackRock or its
affiliates relating to the distribution of Fund shares, services related
to the valuation and pricing of Fund portfolio holdings, direct and indi-
rect benefits to BlackRock and its affiliates from their relationship with
the Fund and advice from independent legal counsel with respect to
the review process and materials submitted for the Board’s review. The
Board noted the willingness of BlackRock personnel to engage in open,
candid discussions with the Board. The Board did not identify any par-
ticular information as controlling, and each Board Member may have
attributed different weights to the various items considered.

A. Nature, Extent and Quality of the Services: The Board, including
the Independent Board Members, reviewed the nature, extent and
quality of services provided by BlackRock, including the investment
advisory services and the resulting performance of the Fund. Through-
out the year, the Board compared Fund performance to the perform-
ance of a comparable group of mutual funds, and the performance of
at least one relevant benchmark, if any. The Board met with BlackRock’s
senior management personnel responsible for investment operations,
including the senior investment officers. The Board also reviewed
the materials provided by the Fund’s portfolio management team
discussing Fund performance and the Fund’s investment objective,
strategies and outlook.

The Board considered, among other factors, the number, education
and experience of BlackRock’s investment personnel generally and
the Fund’s portfolio management team, investments by portfolio
managers in the funds they manage, BlackRock’s portfolio trading

capabilities, BlackRock’s use of technology, BlackRock’s commitment
to compliance and BlackRock’s approach to training and retaining port-
folio managers and other research, advisory and management personnel.
The Board also reviewed a general description of BlackRock’s compen-
sation structure with respect to the Fund’s portfolio management team
and BlackRock’s ability to attract and retain high-quality talent.

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

B. The Investment Performance of the Fund and BlackRock: The
Board, including the Independent Board Members, also reviewed
and considered the performance history of the Fund. In preparation
for the May 5, 2009 meeting, the Board was provided with reports,
independently prepared by Lipper, which included a comprehensive
analysis of the Fund’s performance. The Board also reviewed a narra-
tive and statistical analysis of the Lipper data that was prepared by
BlackRock, which analyzed various factors that affect Lipper’s rankings.
In connection with its review, the Board received and reviewed infor-
mation regarding the investment performance of the Fund as com-
pared to a representative group of similar funds as determined by
Lipper and to all funds in the Fund’s applicable Lipper category. The
Board was provided with a description of the methodology used by
Lipper to select peer funds. The Board regularly reviews the perform-
ance of the Fund throughout the year. The Board attaches more
importance to performance over relatively long periods of time,
typically three to five years.

BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2009 23

Disclosure of Investment Advisory Agreement and Sub-Advisory Agreement (continued)

The Board noted that the Fund ranked in the second quartile against
its Lipper Performance Universe for each of the one-, three- and five-
year periods reported.

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

The Board received and reviewed statements relating to BlackRock’s
financial condition and profitability with respect to the services it
provided the Fund. The Board was also provided with a profitability
analysis that detailed the revenues earned and the expenses incurred
by BlackRock for services provided to the Fund. The Board reviewed
BlackRock’s profitability with respect to the Fund and other funds
the Board currently oversees for the year ended December 31, 2008
compared to available aggregate profitability data provided for the
year ended December 31, 2007. The Board reviewed BlackRock’s
profitability with respect to other fund complexes managed by the
Manager and/or its affiliates. The Board reviewed BlackRock’s assump-
tions and methodology of allocating expenses in the profitability analy-
sis, noting the inherent limitations in allocating costs among various
advisory products. The Board recognized that profitability may be
affected by numerous factors including, among other things, fee
waivers and expense reimbursements by the Manager, the types of
funds managed, expense allocations and business mix, and therefore
comparability of profitability is somewhat limited.

The Board noted that, in general, individual fund or product line
profitability of other advisors is not publicly available. Nevertheless,
to the extent such information is available, the Board considered
BlackRock’s operating margin in general compared to the operating
margin for leading investment management firms whose operations
include advising open-end funds, among other product types. The
comparison indicated that operating margins for BlackRock with
respect to its registered funds are consistent with margins earned by
similarly situated publicly traded competitors. In addition, the Board
considered, among other things, certain third party data comparing
BlackRock’s operating margin with that of other publicly-traded asset

management firms, which concluded that larger asset bases do not,
in themselves, translate to higher profit margins.

In addition, the Board considered the cost of the services provided
to the Fund by BlackRock, and BlackRock’s and its affiliates’ profits
relating to the management and distribution of the Fund and the other
funds advised by BlackRock and its affiliates. As part of its analysis,
the Board reviewed BlackRock’s methodology in allocating its costs
to the management of the Fund. The Board also considered whether
BlackRock has the financial resources necessary to attract and retain
high quality investment management personnel to perform its obliga-
tions under the Agreements and to continue to provide the high quality
of services that is expected by the Board.

The Board noted that the Fund’s contractual advisory fees, which do
not take into account any expense reimbursements or fee waivers,
were lower than or equal to the median contractual advisory fees paid
by the Fund’s Peers.

D. Economies of Scale: The Board, including the Independent Board
Members, considered the extent to which economies of scale might
be realized as the assets of the Fund increase and whether there
should be changes in the advisory fee rate or structure in order to
enable the Fund to participate in these economies of scale, for exam-
ple through the use of breakpoints in the advisory fee based upon
the assets of the Fund. The Board considered that the funds in the
BlackRock fund complex share some common resources and, as a
result, an increase in the overall size of the complex could permit
each fund to incur lower expenses than it would otherwise as a stand-
alone entity. The Board also considered BlackRock’s overall operations
and its efforts to expand the scale of, and improve the quality of,
its operations.

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

Disclosure of Investment Advisory Agreement and Sub-Advisory Agreement (concluded)

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

Conclusion

The Board, including the Independent Board Members, unanimously
approved the continuation of the Advisory Agreement between the
Manager and the Fund for a one-year term ending June 30, 2010 and
the Sub-Advisory Agreement between the Manager and Sub-Advisor
with respect to the Fund for a one-year term ending June 30, 2010.
Based upon its evaluation of all these factors in their totality, the
Board, including the Independent Board Members, was satisfied that
the terms of the Agreements were fair and reasonable and in the best

interest of the Fund and its shareholders. In arriving at a decision to
approve the Agreements, the Board did not identify any single factor
or group of factors as all-important or controlling, but considered all
factors together, and different Board Members may have attributed
different weights to the various factors considered. The Independent
Board Members were also assisted by the advice of independent
legal counsel in making this determination. The contractual fee
arrangements for the Fund reflect the results of several years of
review by the Board Members and predecessor Board Members, and
discussions between such Board Members (and predecessor Board
Members) and BlackRock. Certain aspects of the arrangements may
be the subject of more attention in some years than in others, and
the Board Members’ conclusions may be based in part on their con-
sideration of these arrangements in prior years.
