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 underperformed 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 MuniYield New Jersey Fund, Inc. (MYJ) (the "Fund") seeks to
      provide shareholders with as high a level of current income exempt from
      federal and New Jersey income taxes as is consistent with its investment
      policies and prudent investment management by investing primarily in a
      portfolio of long-term, investment grade municipal obligations the
      interest on which, in the opinion of bond counsel to the issuer, is exempt
      from federal income tax and New Jersey personal income taxes.

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

      For the six months ended May 31, 2008, the Fund returned 7.36% based on
      market price and (0.02%) based on net asset value ("NAV"). For the same
      period, the closed-end Lipper New Jersey Municipal Debt Funds category
      posted an average return of (1.23%) on a NAV basis. All returns reflect
      reinvestment of dividends. The Fund's outperformance resulted primarily
      from its relatively neutral duration position, which proved beneficial
      during a period of rising tax-exempt interest rates. A generally high
      credit quality profile also benefited comparative results, as credit
      spreads remained wide.

            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 to seek to enhance the yield and NAV of its Common
Stock. However, these objectives cannot be achieved in all interest rate
environments.

To leverage, the Fund issues Preferred Stock, which pays dividends at prevailing
short-term interest rates, and invests the proceeds in long-term municipal
bonds. The interest earned on these investments is paid to Common Stock
shareholders in the form of dividends, and the value of these portfolio holdings
is reflected in the per share net asset value of the Fund's Common Stock.
However, in order to benefit Common Stock shareholders, the yield curve must be
positively sloped; that is, short-term interest rates must be lower than
long-term interest rates. At the same time, a period of generally declining
interest rates will benefit Common Stock shareholders. If either of these
conditions change, then the risks of leveraging will begin to outweigh the
benefits.

To illustrate these concepts, assume a fund's Common Stock capitalization of
$100 million and the issuance of Preferred Stock for an additional $50 million,
creating a total value of $150 million available for investment in long-term
municipal bonds. If prevailing short-term interest rates are approximately 3%
and long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million of Preferred
Stock based on the lower short-term interest rates. At the same time, the fund's
total portfolio of $150 million earns income based on long-term interest rates.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term investments,
and therefore the Common Stock shareholders are the beneficiaries of the
incremental yield. However, if short-term interest rates rise, narrowing the
differential between short-term and long-term interest rates, the incremental
yield pickup on the Common Stock will be reduced or eliminated completely. At
the same time, the market value of the fund's Common Stock (that is, its price
as listed on the New York Stock Exchange) may, as a result, decline.
Furthermore, if long-term interest rates rise, the Common Stock's NAV will
reflect the full decline in the price of the portfolio's investments, since the
value of the fund's Preferred Stock does not fluctuate. In addition to the
decline in NAV, the market value of the fund's Common Stock may also decline.

In addition, the Fund may from time to time leverage its assets through the use
of tender option bond ("TOB") programs. In a typical TOB program, the Fund
transfers one or more municipal bonds to a TOB trust, which issues short-term
variable rate securities to third-party investors and a residual interest to the
Fund. The cash received by the TOB trust from the issuance of the short-term
securities (less transaction expenses) is paid to the Fund, which invests the
cash in additional portfolio securities. The distribution rate on the short-term
securities is reset periodically (typically every seven days) through a
remarketing of the short-term securities. Any income earned on the bonds in the
TOB trust, net of expenses incurred by the TOB trust, that is not paid to the
holders of the short-term securities is paid to the Fund. In connection with
managing the Fund's assets, the Fund's investment advisor may at any time
retrieve the bonds out of the TOB trust typically within seven days. TOB
investments generally will provide the Fund with economic benefits in periods of
declining short-term interest rates, but expose the Fund to risks during periods
of rising short-term interest rates similar to those associated with Preferred
Stock issued by the Fund, as described above. Additionally, fluctuations in the
market value of municipal securities deposited into the TOB trust may adversely
affect the Fund's NAV per share. (See Note 1 of the Notes to Financial
Statements for details of municipal bonds transferred to TOB trusts.)

Under the Investment Company Act of 1940, the Fund is permitted to issue
Preferred Stock in an amount up to 50% of its total managed assets at the time
of issuance. The Fund also anticipates that its total economic leverage, which
includes Preferred Stock and TOBs, will not exceed 50% of its total managed
assets. As of May 31, 2008, the Fund had economic leverage of 39% 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.

o     Effective December 1, 2007, the Fund adopted Financial Accounting Standard
      Board ("FASB") Statement of Financial Accounting Standards No. 157, "Fair
      Value Measurements" ("FAS 157"). FAS 157 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:

      o     Level 1 -- price quotations in active markets/exchanges for
            identical securities

      o     Level 2 -- other observable inputs (including, but not limited to:
            quoted prices for 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)

      o     Level 3 -- unobservable inputs based on the best information
            available in the circumstance, to the extent observable inputs are
            not available (including the Fund's own assumption used in
            determining the fair value of investments)

      The inputs or methodology used for valuing securities are not necessarily
      an indication 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 May 31, 2008 in
      determining the fair valuation of the Fund's investments:

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

Notes to Financial Statements (Unaudited)

1. Significant Accounting Policies:

BlackRock MuniYield New Jersey Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as a
non-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: Municipal Investments are valued on the basis of
prices provided by dealers or pricing services selected under the supervision of
the Fund's Board of Directors (the "Board"). In determining the value of a
particular investment, pricing services may use certain information with respect
to transactions in such investments, quotations from dealers, pricing matrixes,
market transactions in comparable investments and various relationships between
investments. Short-term securities are valued at amortized cost. Swap agreements
are valued by quoted fair values received daily by the Fund's pricing service.

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 sub-advisor deems relevant. The pricing of all Fair Value Assets
is subsequently reported to the Board or a committee thereof.

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 due to an unfavorable
change in the price of the underlying security or if the counterparty does not
perform under the contract.

o     Forward interest rate swaps -- The Fund may enter into forward interest
      rate swaps, in which the Fund and the counterparty agree to make periodic
      net payments on a specified notional contract amount, commencing on a
      specified future effective date, unless terminated earlier. These periodic
      payments received or made by the Fund are recorded in the accompanying
      Statements of Operations as realized gains or losses, respectively. Gains
      or losses are also realized upon termination of the swap agreements. Swaps
      are marked-to-market daily and changes in value are recorded as unrealized
      appreciation (depreciation). The Fund generally intends to close each
      forward interest rate swap before the accrual date specified in the
      agreement and therefore avoid entering into the interest rate swap
      underlying each forward interest rate swap.

Municipal Bonds Transferred to Tender Option Bond Trusts: The Fund leverages its
assets through the use of tender option bond trusts ("TOBs"). A TOB is
established by a third party sponsor forming a special purpose entity, into
which one or more funds or an agent on behalf of the funds, transfers municipal
securities. Other funds managed by the investment advisor may also contribute
municipal securities to a TOB into which the Fund has contributed securities. A
TOB typically issues two classes of beneficial interests: short-term floating
rate certificates, which are sold to third party investors, and residual
certificates ("TOB Residuals"), which are generally issued to the participating
funds that made the transfer. The TOB Residuals held by the Fund include the
right of the Fund (1) to cause the holders of a proportional share of the
floating rate certificates to tender their certificates at par, and (2) to
transfer, within seven days, a corresponding share of the municipal securities
from the TOB to the Fund. The cash received by the TOB from the sale of the
short-term floating rate certificates, less transaction expenses, is paid to the
Fund, which typically invests the cash in additional municipal securities. The
Fund's transfer of the municipal securities to a TOB is accounted for as a
secured borrowing, therefore the municipal securities deposited into a TOB are
presented in the Fund's Schedule of Investments and the proceeds from the
transaction are reported as a liability of the Fund.

Interest income from the underlying securities is recorded by the Fund on an
accrual basis. Interest expense incurred on the secured borrowing and other
expenses related to remarketing, administration and trustee services to a TOB
are reported as expenses of the Fund. The floating rate certificates have
interest rates that generally reset weekly and their holders have the option to
tender certificates to the TOB for redemption at par at each reset date. As of
May 31, 2008, the aggregate value of the underlying municipal securities
transferred to TOBs was $29,317,582, the related liability for trust
certificates was $17,795,000 and the range of interest rates was 1.67% to
2.291%.

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

Notes to Financial Statements (continued)

Financial transactions executed through TOBs generally will underperform the
market for fixed rate municipal bonds in a rising interest rate environment, but
tend to outperform the market for fixed rate bonds when interest rates decline
or remain relatively stable. Should short-term interest rates rise, the Fund's
investments in TOBs likely will adversely affect the Fund's investment income
and dividends to Common Stock shareholders. Fluctuations in the market value of
municipal securities deposited into the TOB may adversely affect the Fund's net
asset value per share.

Zero-Coupon Bonds: The Fund may invest in zero-coupon bonds, which are normally
issued at a significant discount from face value and do not provide periodic
interest payments. Zero-coupon bonds may experience greater volatility in market
value than similar maturity debt obligations which provide for regular interest
payments.

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., swaps and when-issued
securities), 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 date.
Interest income is recognized on the accrual method. 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. Dividends and distributions to holders of Preferred Stock are accrued and
determined as described in Note 4.

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

Effective May 30, 2008, the Fund implemented Financial Accounting Standards
Board ("FASB") Interpretation No. 48, "Accounting for Uncertainty in Income
Taxes -- an interpretation of FASB Statement No. 109" ("FIN 48"). FIN 48
prescribes the minimum recognition threshold a tax position must meet in
connection with accounting for uncertainties in income tax positions taken or
expected to be taken by an entity, including investment companies, before being
measured and recognized in the financial statements. The investment advisor has
evaluated the application of FIN 48 to the Fund, and has determined that the
adoption of FIN 48 does not have a material impact on the Fund's financial
statements. The Fund files U.S. federal and various state and local tax returns.
No income tax returns are currently under examination. The statute of
limitations on the Fund's U.S. federal tax returns remain open for the years
ended November 30, 2004 through November 30, 2006. 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 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 had 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.

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 that Fund are charged to the 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.

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

Notes to Financial Statements (continued)

2. Investment Advisory Agreement and Other Transactions with Affiliates:

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

The Advisor is responsible for the management of the 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 0.50% of the average daily
value of the Fund's net assets, plus the proceeds from the issuance of Preferred
Stock and TOBs.

The Advisor has agreed to waive its investment advisory fees by the amount of
investment advisory fees the Fund pays to the Advisor indirectly through its
investment in affiliated money market funds. This amount is included in fees
waived by the Advisor on the Statement of Operations.

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

For the six months ended May 31, 2008, the Fund reimbursed the Advisor $2,593
for certain accounting services, which is included in accounting services in the
Statement of Operations.

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

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the six
months ended May 31, 2008 were $23,394,989 and $29,863,540, respectively.

4. Capital Stock Transactions:

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

Common Stock

Shares issued and outstanding during the six months ended May 31, 2008 and the
year ended November 30, 2007 remained constant.

Preferred Stock

Preferred Stock of the Fund has a par value of $0.05 per share (Series A and
Series B Shares) and $0.10 per share (Series C Shares) and a liquidation
preference of $25,000 per share, plus accrued and unpaid dividends, that
entitles its holders to receive cash dividends at varying annualized rates for
each dividend period. The yields in effect at May 31, 2008 were as follows:
Series A, 3.454%, Series B, 2.559% and Series C, 2.589%. Shares issued and
outstanding during the six months ended May 31, 2008 and the year ended November
30, 2007 remained constant.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate of 0.25%, calculated on the aggregate principal amount. For
the six months ended May 31, 2008, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, a wholly owned subsidiary of Merrill Lynch, earned commissions of
$82,660.

Dividends on seven-day Preferred Stock are cumulative at a rate which is reset
every seven days based on the results of an auction. If the Preferred Stock
fails to clear the auction on an auction date, the Fund is required to pay the
maximum applicable rate on the Preferred Stock to holders of such shares for
each successive dividend period until such time as the stock is successfully
auctioned. The maximum applicable rate on the Preferred Stock for Series A and
B, is the higher of 110% of the AA commercial paper rate or 110% of 90% of the
Kenny S&P 30-day High Grade Index rate divided by 1.00 minus the marginal tax
rate. The maximum applicable rate on the Preferred Stock for Series C is the
higher of 110% plus or multiplied by the Telerate/BBA LIBOR; or 90% of the Kenny
S&P 30-day High-Grade Index rate divided by 1.00 minus the marginal tax rate.
During the six months ended May 31, 2008, the Preferred Stock of the Fund was
successfully auctioned at each auction date until February 13, 2008. The low,
high and average dividend rates on the Preferred Stock for the Fund for the six
months ended May 31, 2008 were as follows:

--------------------------------------------------------------------------------
                                                       Low      High     Average
--------------------------------------------------------------------------------
Series A ........................................    2.559%    4.356%     3.460%
Series B ........................................    2.589%    4.356%     3.487%
Series C ........................................    2.800%    5.198%     3.864%
--------------------------------------------------------------------------------

Since February 13, 2008, the Preferred Stock of the Fund failed to clear any of
its auctions. As a result, the Preferred Stock dividend rates were reset to the
maximum applicable rate, which ranged from 2.559% to 5.198%. A failed auction is
not an event of default for the Fund but it is a liquidity event for the holders
of the Preferred Stock. A failed auction occurs when there are more sellers of a
fund's auction rate preferred stock than buyers. It is impossible to predict how
long this imbalance will last. An auction for the Fund's Preferred Stock may not
occur for some time, if ever, and even if liquidity does resume, holders of
Preferred Stock may not have the ability to sell the Preferred Stock at its
liquidation preference.

The Fund may not declare dividends or make other distributions on Common Stock
or purchase any such shares if, at the time of the declaration, distribution or
purchase, asset coverage with respect to the outstanding Preferred Stock is less
than 200%.


            BLACKROCK MUNIYIELD NEW JERSEY FUND, INC.      MAY 31, 2008       15



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

Notes to Financial Statements (concluded)

The Preferred Stock is redeemable at the option of the Fund, in whole or in
part, on any dividend payment date at $25,000 per share plus any accumulated
unpaid dividends whether or not declared. The Preferred Stock is also subject to
mandatory redemption at $25,000 per share plus any accumulated or unpaid
dividends, whether or not declared, if certain requirements relating to the
composition of the assets and liabilities of the Fund, as set forth in the
Fund's Articles Supplementary, are not satisfied.

The holders of Preferred Stock have voting rights equal to the holders of Common
Stock (one vote per share) and will vote together with holders of Common Stock
(one vote per share) as a single class. However, holders of Preferred Stock,
voting as a separate class, are also entitled to elect two Directors for the
Fund. In addition, the 1940 Act requires that along with approval by
shareholders that might otherwise be required, the approval of the holders of a
majority of any outstanding Preferred Stock, voting separately as a class would
be required to (a) adopt any plan of reorganization that would adversely affect
the Preferred Stock, (b) change the Fund's subclassification as a closed-end
investment company or change its fundamental investment restrictions or (c)
change its business so as to cease to be an investment company.

5. Capital Loss Carryforward:

On November 30, 2007, the Fund had a capital loss carryforward of $1,019,340, of
which $779,784 expires in 2008 and $239,556 expires in 2012. This amount will be
available to offset future realized capital gains.

6. Concentration Risk:

The Fund's investments are concentrated in certain states, which may be affected
by adverse financial, social, environmental, economic, regulatory and political
factors.

Many municipalities insure repayment of their bonds, which reduces the risk of
loss due to issuer default. The market value of these bonds may fluctuate for
other reasons and there is no assurance that the issuer will meet its
obligation.

7. Subsequent Event:

The Fund paid a tax-exempt income dividend to holders of Common Stock in the
amount of $0.058000 per share on July 1, 2008 to shareholders of record on June
16, 2008.

The dividends declared on Preferred Stock for the period June 1, 2008 to June
30, 2008 were as follows: Series A, $117,252; Series B, $72,296 and Series C,
$56,435.

On June 2, 2008, the Fund announced the following redemptions of Preferred Stock
at a price of $25,000 per share plus any accrued and unpaid dividends through
the redemption date:

--------------------------------------------------------------------------------
                                       Redemption    Shares to be     Aggregate
Series                                    Date         Redeemed         Price
--------------------------------------------------------------------------------
   A ..............................     6/26/2008         288        $ 7,200,000
   B ..............................     6/25/2008         180        $ 4,500,000
   C ..............................     6/24/2008         103        $ 2,575,000
--------------------------------------------------------------------------------

The Fund financed the Preferred Stock redemptions with cash received from TOB
transactions.

Disclosure of Investment Advisory Agreement and Subadvisory Agreement

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 MuniYield New Jersey Fund, 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 Investment Management, LLC (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.

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

Disclosure of Investment Advisory Agreement and Subadvisory Agreement
(continued)

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, 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 of the Peers' median
performance).

The Board reviewed a narrative analysis of the Peer rankings prepared by Lipper
and reviewed 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.

(continued)

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 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.

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 Advisor 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. The Board noted that these payments were less than the Advisors' costs
for providing these services, if applicable. 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 fee structures. Information provided by
Lipper also revealed that only one closed-end fund complex used a complex-level
breakpoint structure.

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.

--------------------------------------------------------------------------------
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
independent fiduciary, the Committee shall determine how to vote the proxy after
consulting with the Investment Adviser's Portfolio Management Group and/or the
Investment Adviser's Legal and Compliance Department and concluding that the
vote cast is in its client's best interest notwithstanding the conflict.
Information on how the Fund voted proxies relating to portfolio securities
during the most recent 12-month period ended June 30 is available without

           (iv)   Potential Material Conflicts of Interest

           BlackRock has built a professional working environment, firm-wide
           compliance culture and compliance procedures and systems designed to
           protect against potential incentives that may favor one account over
           another. BlackRock has adopted policies and procedures that address
           the allocation of investment opportunities, execution of portfolio
           transactions, personal trading by employees and other potential
           conflicts of interest that are designed to ensure that all client
           accounts are treated equitably over time. Nevertheless, BlackRock
           furnishes investment management and advisory services to numerous
           clients in addition to the Fund, and BlackRock may, consistent with
           applicable law, make investment recommendations to other clients or
           accounts (including accounts which are hedge funds or have
           performance or higher fees paid to BlackRock, or in which portfolio
           managers have a personal interest in the receipt of such fees), which
           may be the same as or different from those made for the Funds. 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 a Fund. In this regard, it
           should be noted that Mr. Jaeckel currently manages certain accounts
           that are subject to performance fees. In addition, Mr. Jaeckel
           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.



           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 a
           combination of market-based indices (e.g., Lehman Brothers Municipal
           Bond 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. 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 except Mr. Stuebe 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.
           Stuebe did not beneficially own any stock issued by the Fund.
