Annual Report

This report provides management's discussion of fund performance for
AllianceBernstein Mid-Cap Growth Fund (the "Fund") for the annual reporting
period ended July 31, 2006.

Investment Objective and Policies

This open-end fund seeks long-term growth of capital. The Fund normally invests
substantially all of its assets in high-quality common stocks that
AllianceBernstein expects to increase in value. Under normal circumstances, the
Fund invests at least 80% of its net assets in common stocks of
mid-capitalization companies. This Fund may also invest in foreign securities.

Investment Results

The table on page 4 shows the Fund's performance compared to its benchmark, the
Russell MidCap Growth Index, for the six- and 12-month periods ended July 31,
2006. Recent weakness in the equity markets, particularly among growth stocks,
has been largely indiscriminate and appears to predominantly reflect "macro"
concerns. Nevertheless, both market and Fund performance was negative over the
review period.

The Fund underperformed its benchmark for both the six- and 12-month periods
ended July 31, 2006.

During the 12-month period ended July 31, 2006, the Fund's underperformance was
largely attributable to stock selection. On a sector selection basis, the
Fund's significant underweight in the energy sector was the largest detractor
from relative performance. An underweight in the materials and processing
sector also detracted from performance. The largest contribution was
attributable to a modest overweight in utilities, followed by a modest
underweight in producer durables.

During the six-month period ended July 31, 2006, the majority of the Fund's
underperformance relative to the benchmark was attributable to stock selection.
In terms of sector selection, the Fund's significant overweight in the
technology sector made the largest contribution to its underperformance
relative to the benchmark. An underweight in the energy sector also detracted
from performance. The Fund's modest overweight in the utilities sector was the
largest contributor to performance, followed by the impact of a slight
overweight in the financial services sector.

Market Review and Investment Strategy

In the six-month period ending July 31, 2006, an early period of calm proved
short-lived, as the equity markets sold off sharply in May, and did not recover
convincingly as July came to a close. The price of oil, however, exhibited
strength throughout the period, rising from under $60/barrel in mid-February to
nearly $75 at the end of July. The bond markets sold off from February through
mid-May, with the yield on the 10-year Treasury rising from a low of 4.52% in
February to a high of 5.19% on May 12. The bond market later rallied, however,
sending the yield back below 5% by July 31.


ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 1


Economic growth has moderated over time, as illustrated by U.S. gross domestic
product (GDP), with an initial reading for second quarter real GDP growth of
just 2.5% on an annualized basis, as compared to a more robust 5.6% final mark
for the prior quarter. The strong rally in commodity prices continued into 2006
through mid-May, before declining concurrently with the equity markets. The
U.S. Federal Reserve raised interest rates by 25 basis points at each of the
eight meetings over the 12-month period ending July 31, 2006. Corporate profit
growth remained strong despite rising wages, raw material prices and interest
rates. Capital spending continued to lag profit growth; however, some companies
choose to use excess cash for share repurchases, dividends and merger activity.

In terms of the Fund's positioning over the 12-month period ended July 31,
2006, an overweight in technology benefited from a proliferation of data-rich
content on the internet, which created demand for products that support the
transmission and routing of this traffic. An underweight in energy was
maintained despite rising oil prices as storage levels of crude oil and other
derivative products remain elevated and as demand for these products remains
constrained. The Fund's exposure in the financial sector was increased modestly
from the prior 12 months, with a focus on companies that stand to benefit from
the increased trading volumes that result as the domestic equity markets
incorporate electronic trading.

As economic growth decelerates, the manager expects the stock market to reward
fundamental success, according differentiated valuation to companies that
continue to achieve superior growth and rising earnings projections. Growth
stocks continue to sell at a historically low premium to the broad market. This
has enabled the manager to continue a strategy of "trading up" to companies our
research indicates will be the growth leaders in the emerging cycle. The Fund
continues to be invested in companies exhibiting strong top line growth and
whose fundamentals remain sound.

HISTORICAL PERFORMANCE

An Important Note About the Value of Historical Performance

The performance shown on the following pages represents past performance and
does not guarantee future results. Current performance may be lower or higher
than the performance information shown. You may obtain performance information
current to the most recent month-end by visiting www.alliancebernstein.com.

The investment return and principal value of an investment in the Fund will
fluctuate, so that your shares, when redeemed, may be worth more or less than
their original cost. You should consider the investment objectives, risks,
charges and expenses of the Fund carefully before investing. For a free copy of
the Fund's prospectus, which contains this and other information, visit our
website at www.alliancebernstein.com or call your financial advisor or
AllianceBernstein Investments at 800.227.4618. You should read the prospectus
carefully before you invest.

All fees and expenses related to the operation of the Fund have been deducted.
NAV returns do not reflect sales charges; if sales charges were reflected, the
Fund's quoted performance would be lower. SEC returns reflect the applicable
sales charges for each share class: a 4.25% maximum front-end sales charge for
Class A shares; the applicable contingent deferred sales charge for Class B
shares (4% year 1, 3% year 2, 2% year 3, 1% year 4); a 1% 1 year contingent
deferred sales charge for Class C shares. Returns for the different share
classes will vary due to different expenses associated with each class.
Performance assumes reinvestment of distributions and does not account for
taxes.

Benchmark Disclosure

The unmanaged Russell MidCap Growth Index does not reflect fees and expenses
associated with the active management of a mutual fund portfolio. The Index
measures the performance of those Russell mid-cap companies with higher
price-to-book ratios and higher forecasted growth values. The stocks are also
members of the Russell 1000 Growth Index. An investor cannot invest directly in
an index, and its results are not indicative of the performance for any
specific investment, including the Fund.

A Word About Risk

Mid-cap stocks may have limited marketability and may be subject to more abrupt
or erratic market movements than large-cap stocks. The Fund can invest in
foreign securities. Foreign markets can be more volatile than the U.S. market
due to increased risks of adverse issuer, political, regulatory, market or
economic developments. In addition, fluctuations in the value of investments in
foreign currency denominated securities may be magnified by changes in foreign
exchange rates. While the Fund invests principally in common stocks and other
equity securities, in order to achieve its investment objectives, the Fund may
at times use certain types of investment derivatives, such as options, futures,
forwards and swaps. These instruments involve risks different from, and in
certain cases, greater than, the risks presented by more traditional
investments. These risks are fully discussed in the Fund's prospectus.

6 o ALLIANCEBERNSTEIN MID-CAP GROWTH FUND


FUND EXPENSES

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments, contingent
deferred sales charges on redemptions and (2) ongoing costs, including
management fees; distribution (12b-1) fees; and other Fund expenses. This
example is intended to help you understand your ongoing costs (in dollars) of
investing in the Fund and to compare these costs with the ongoing costs of
investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of
the period and held for the entire period as indicated below.

Actual Expenses

The table below provides information about actual account values and actual
expenses. You may use the information, together with the amount you invested,
to estimate the expenses that you paid over the period. Simply divide your
account value by $1,000 (for example, an $8,600 account value divided by $1,000
= 8.6), then multiply the result by the number under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your account
during this period.

Hypothetical Example for Comparison Purposes

The table below also provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
annual rate of return of 5% before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Fund and other funds by comparing this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads), or contingent deferred sales charges on redemptions.
Therefore, the hypothetical example is useful in comparing ongoing costs only,
and will not help you determine the relative total costs of owning different
funds. In addition, if these transactional costs were included, your costs
would have been higher.

NOTES TO FINANCIAL STATEMENTS
July 31, 2006

NOTE A

Significant Accounting Policies

The AllianceBernstein Mid-Cap Growth Fund, Inc. (the "Fund") is registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund offers Class A, Class B, Class C, Advisor Class,
Class R, Class K and Class I shares. Class A shares are sold with a front-end
sales charge of up to 4.25% for purchases not exceeding $1,000,000. With
respect to purchases of $1,000,000 or more, Class A shares redeemed within one
year of purchase may be subject to a contingent deferred sales charge of 1%.
Class B shares are currently sold with a contingent deferred sales charge which
declines from 4% to zero depending on the period of time the shares are held.
Class B shares will automatically convert to Class A shares eight years after
the end of the calendar month of purchase. Class Cshares are subject to a
contingent deferred sales charge of 1% on redemptions made within the first
year after purchase. Class R and Class K shares are sold without an initial or
contingent deferred sales charge. Advisor Class and Class I shares are sold
without an initial or contingent deferred sales charge and are not subject to
ongoing distribution expenses. All seven classes of shares have identical
voting, dividend, liquidation and other rights, except that the classes bear
different distribution and transfer agency expenses. Each class has exclusive
voting rights with respect to its distribution plan. The financial statements
have been prepared in conformity with U.S. generally accepted accounting
principles which require management to make certain estimates and assumptions
that affect the reported amounts of assets and liabilities in the financial
statements and amounts of income and expenses during the reporting period.
Actual results could differ from those estimates. Additional information about
some of the items discussed in these Notes to Financial Statements is contained
in the Fund's Statement of Additional Information, which is available upon
request. The following is a summary of significant accounting policies followed
by the Fund.

1. Security Valuation

Portfolio securities are valued at their current market value determined on the
basis of market quotations or, if market quotations are not readily available
or are deemed unreliable, at "fair value" as determined in accordance with
procedures established by and under the general supervision of the Fund's Board
of Directors.

In general, the market value of securities which are readily available and
deemed reliable are determined as follows. Securities listed on a national
securities exchange (other than securities listed on The NASDAQ Stock Market,
Inc. ("NASDAQ")) or on a foreign securities exchange are valued at the last
sale price at the close of the exchange or foreign securities exchange. If
there has been no sale on such day, the securities are valued at the mean of
the closing bid and asked prices on such day. Securities listed on more than
one exchange are valued by reference to the principal exchange on which the
securities are traded; securities


ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 15


listed only on NASDAQ are valued in accordance with the NASDAQ Official Closing
Price; listed put or call options are valued at the last sale price. If there
has been no sale on that day, such securities will be valued at the closing bid
prices on that day; open futures contracts and options thereon are valued using
the closing settlement price or, in the absence of such a price, the most
recent quoted bid price. If there are no quotations available for the day of
valuation, the last available closing settlement price is used; securities
traded in the over-the-counter market, ("OTC") are valued at the mean of the
current bid and asked prices as reported by the National Quotation Bureau or
other comparable sources; U.S. Government securities and other debt instruments
having 60 days or less remaining until maturity are valued at amortized cost if
their original maturity was 60 days or less; or by amortizing their fair value
as of the 61st day prior to maturity if their original term to maturity
exceeded 60 days; fixed-income securities, including mortgage backed and asset
backed securities, may be valued on the basis of prices provided by a pricing
service or at a price obtained from one or more of the major broker/dealers. In
cases where broker/dealer quotes are obtained, AllianceBernstein L.P. (prior to
February 24, 2006 known as Alliance Capital Management L.P.) (the "Manager")
may establish procedures whereby changes in market yields or spreads are used
to adjust, on a daily basis, a recently obtained quoted price on a security;
and OTC and other derivatives are valued on the basis of a quoted bid price or
spread from a major broker/dealer in such security.

Securities for which market quotations are not readily available (including
restricted securities) or are deemed unreliable are valued at fair value.
Factors considered in making this determination may include, but are not
limited to, information obtained by contacting the issuer, analysts, analysis
of the issuer's financial statements or other available documents. In addition,
the Fund may use fair value pricing for securities primarily traded in non-U.S.
markets because, most foreign markets close well before the Fund values its
securities at 4:00 p.m., Eastern Time. The earlier close of these foreign
markets gives rise to the possibility that significant events, including broad
market moves, may have occurred in the interim and may materially affect the
value of those securities. To account for this, the Fund may frequently value
many of its foreign equity securities using fair value prices based on third
party vendor modeling tools to the extent available.

2. Currency Translation

Assets and liabilities denominated in foreign currencies and commitments under
forward currency exchange contracts are translated into U.S. dollars at the
mean of the quoted bid and asked prices of such currencies against the U.S.
dollar. Purchases and sales of portfolio securities are translated into U.S.
dollars at the rates of exchange prevailing when such securities were acquired
or sold. Income and expenses are translated into U.S. dollars at rates of
exchange prevailing when accrued.


16 o ALLIANCEBERNSTEIN MID-CAP GROWTH FUND


Net realized gain or loss on foreign currency transactions represents foreign
exchange gains and losses from sales and maturities of foreign fixed income
investments, foreign currency exchange contracts, holding of foreign
currencies, currency gains or losses realized between the trade and settlement
dates on foreign investment transactions, and the difference between the
amounts of dividends, interest and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent amounts actually received or paid.
Net unrealized currency gains and losses from valuing foreign currency
denominated assets and liabilities at period end exchange rates are reflected
as a component of net unrealized appreciation or depreciation of investments
and foreign currency denominated assets and liabilities.

3. Taxes

It is the Fund's policy to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its
investment company taxable income and net realized gains, if any, to
shareholders. Therefore, no provisions for federal income or excise taxes are
required. The Fund may be subject to taxes imposed by countries in which it
invests. Such taxes are generally based on income and/or capital gains earned
or repatriated. Taxes are accrued and applied to net investment income, net
realized gains and net unrealized appreciation/depreciation as such income
and/or gains are earned.

4. Investment Income and Investment Transactions

Dividend income is recorded on the ex-dividend date or as soon as the Fund is
informed of the dividend. Interest income is accrued daily. Investment
transactions are accounted for on the trade date securities are purchased or
sold. Investment gains and losses are determined on the identified cost basis.
The Fund amortizes premiums and accretes discounts as adjustments to interest
income.

5. Class Allocations

All income earned and expenses incurred by the Fund are borne on a pro rata
basis by each outstanding class of shares, based on the proportionate interest
in the Fund represented by the net assets of such class, except for class
specific expenses which are allocated to the respective class. Realized and
unrealized gains and losses are allocated among the various share classes based
on their relative net assets.

6. Dividends and Distributions

Dividends and distributions to shareholders, if any, are recorded on the
exdividend date. Income dividends and capital gains distributions are
determined in accordance with federal tax regulations and may differ from those
determined in accordance with U.S. generally accepted accounting principles. To
the extent these differences are permanent, such amounts are reclassified
within the capital accounts based on their federal tax basis treatment;
temporary differences do not require such reclassification.

NOTE B

Management Fee and Other Transactions With Affiliates

Under the terms of the management agreement, the Fund pays the Manager a fee at
an annual rate of .75% on the first $500 million of average daily net assets,
..65% on the next $500 million of average daily net assets and .55% on average
daily net assets in excess of $1 billion. Such fee is accrued daily and paid
monthly.

Pursuant to the management agreement, the Fund paid $90,312 to the Manager
representing the cost of certain legal and accounting services provided to the
Fund by the Manager for the year ended July 31, 2006.

The Fund compensates AllianceBernstein Investor Services, Inc. (prior to
February 24, 2006 known as Alliance Global Investor Services, Inc.) ("ABIS"), a
wholly-owned subsidiary of the Manager, under a Transfer Agency Agreement for
providing personnel and facilities to perform transfer agency services for the
Fund. ABIS may make payments to intermediaries that provide omnibus account
services, sub accounting services and/or networking services. Such compensation
retained by ABIS amounted to $1,018,647 for the year ended July 31, 2006.

For the year ended July 31, 2006, the Fund's expenses were reduced by $49,960
under an expense offset arrangement with ABIS.

AllianceBernstein Investments, Inc. (prior to February 24, 2006 known as
AllianceBernstein Investment Research and Management, Inc.) (the
"Distributor"), a wholly-owned subsidiary of the Manager, serves as the
distributor of the Fund's shares. The Distributor has advised the Fund that it
has retained front-end sales charges of $22,370 from the sale of Class A shares
and received $6,757, $62,955 and $4,382 in contingent deferred sales charges
imposed upon redemptions by shareholders of Class A, Class B and Class C
shares, respectively, for the year ended July 31, 2006.

Brokerage commissions paid on investment transactions for the year ended July

Distribution Services Agreement

The Fund has adopted a Distribution Services Agreement (the "Agreement")
pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the
Agreement, the Fund pays distribution and servicing fees to the Distributor at
an annual rate of up to .30% of the Fund's average daily net assets
attributable to Class A shares, 1% of the average daily net assets attributable
to both Class B and Class C shares, .50% of the Fund's average daily net assets
attributable to Class R shares and .25% of the Fund's average daily net assets

shares. There are no distribution and servicing fees on the Advisor Class and
Class I shares. The fees are accrued daily and paid monthly. Payments under the
Class A plan are currently limited to .23% of average daily net assets
attributable to Class A shares. Prior to April 1, 2006, payments under the
Class A plan were limited to .22% of average daily net assets attributable to
Class A shares. The Agreement provides that the Distributor will use such
payments in their entirety for distribution assistance and promotional
activities. The Distributor has incurred expenses in excess of the distribution
costs reimbursed by the Fund in the amount of $6,446,896, $2,269,571, $6,839
and $848, for Class B, Class C, Class R and Class K shares, respectively. Such
costs may be recovered from the Fund in future periods so long as the Agreement
is in effect. In accordance with the Agreement, there is no provision for
recovery of unreimbursed distribution costs incurred by the Distributor beyond
the current fiscal year for Class A shares. The Agreement also provides that
the Manager may use its own resources to finance the distribution of the Fund's
shares.

Securities Lending

The Fund has entered into a securities lending agreement with UBS Securities
LLC (formerly UBS Warburg LLC) (the "Lending Agent"). Under the terms of the
agreement, the Lending Agent, on behalf of the Fund, administers the lending of
portfolio securities to certain broker-dealers. In return, the Fund receives
fee income from the lending transactions or it retains a portion of interest on
the investment of any cash received as collateral. The Fund also continues to
receive dividends or interest on the securities loaned. Unrealized gain or loss
on the value of the securities loaned that may occur during the term of the
loan will be reflected in the accounts of the Fund. All loans are continuously
secured by collateral exceeding the value of the securities loaned. All
collateral


ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 19


consists of either cash or U.S. Government securities. The Lending Agent may
invest the cash collateral received in an eligible money market vehicle in
accordance with the investment restrictions of the Fund. The Lending Agent will
indemnify the Fund for any loss resulting from a borrower's failure to return a
loaned security when due. As of July 31, 2006, the Fund had loaned securities
with a value of $157,017,721 and received cash collateral which was invested in
a money market fund valued at $166,385,114 as included in the accompanying
portfolio of investments. For the year ended July 31, 2006, the Fund earned fee
income of $1,620,156 which is included in the accompanying statement of
operations.

Risks Involved in Investing in the Fund

Foreign Securities Risk--Investing in securities of foreign companies or
foreign governments involves special risks which include changes in foreign
currency exchange rates and the possibility of future political and economic
developments which could adversely affect the value of such securities.
Moreover, securities of many foreign companies or foreign governments and their
markets may be less liquid and their prices more volatile than those of
comparable U.S. companies or of the U.S. government.

Indemnification Risk--In the ordinary course of business, the Fund enters into
contracts that contain a variety of indemnifications. The Fund's maximum
exposure under these arrangements is unknown. However, the Fund has not had
prior claims or losses pursuant to these indemnification provisions and expects
the risk of loss thereunder to be remote.

NOTE H

Joint Credit Facility

A number of open-end mutual funds managed by the Adviser, including the Fund,
participate in a $250 million revolving credit facility (the "Facility")
intended to provide short-term financing if necessary, subject to certain
restrictions in connection with abnormal redemption activity. Commitment fees
related to the Facility are paid by the participating funds and are included in
miscellaneous expenses in the statement of operations. The Fund did not utilize
the Facility during the year ended July 31, 2006.

NOTE I

Distributions to Shareholders

The tax character of distributions paid during the fiscal year ended July 31,
2006 were as follows:

                                                                  2006
                                                             --------------
Distributions paid from:
  Long-term capital gain                                     $   75,193,441
  Total taxable distributions                                    75,193,441
  Total distributions paid                                   $   75,193,441

As of July 31, 2006, the components of accumulated earnings/(deficit) on a tax
basis were as follows:

Undistributed ordinary income                                $   48,582,960
Undistributed long term capital gain                             27,189,255
Unrealized appreciation/(depreciation)                          (60,130,969)(a)
Total accumulated earnings/(deficit)                         $   15,641,246

(a)  The difference between book-basis and tax-basis unrealized
appreciation/(depreciation) is attributable primarily to the tax deferral of
losses on wash sales.


22 o ALLIANCEBERNSTEIN MID-CAP GROWTH FUND


During the current fiscal year, permanent differences, primarily due to net
operating loss, resulted in a decrease to net investment loss and a
corresponding decrease in accumulated net realized gain on investments. This
reclassification had no effect on net assets.

NOTE J

Legal Proceedings

As has been previously reported, the staff of the U.S. Securities and Exchange
Commission ("SEC") and the Office of New York Attorney General ("NYAG") have
been investigating practices in the mutual fund industry identified as "market
timing" and "late trading" of mutual fund shares. Certain other regulatory
authorities have also been conducting investigations into these practices
within the industry and have requested that the Adviser provide information to
them. The Adviser has been cooperating and will continue to cooperate with all
of these authorities.

On December 18, 2003, the Adviser confirmed that it had reached terms with the
SEC and the NYAG for the resolution of regulatory claims relating to the
practice of "market timing" mutual fund shares in some of the AllianceBernstein
Mutual Funds. The agreement with the SEC is reflected in an Order of the
Commission ("SEC Order"). The agreement with the NYAG is memorialized in an
Assurance of Discontinuance dated September 1, 2004 ("NYAG Order"). Among the
key provisions of these agreements are the following:

(i)  The Adviser agreed to establish a $250 million fund (the "Reimbursement
Fund") to compensate mutual fund shareholders for the adverse effects of market
timing attributable to market timing relationships described in the SEC Order.
According to the SEC Order, the Reimbursement Fund is to be paid, in order of
priority, to fund investors based on (i) their aliquot share of losses suffered
by the fund due to market timing, and (ii) a proportionate share of advisory
fees paid by such fund during the period of such market timing;

(ii)  The Adviser agreed to reduce the advisory fees it receives from some of
the AllianceBernstein long-term, open-end retail funds until December 31, 2008;
however, it is not expected that the Fund will have its fee reduced; and

(iii)  The Adviser agreed to implement changes to its governance and compliance
procedures. Additionally, the SEC Order and the NYAG Order contemplate that the
Adviser's registered investment company clients, including the Fund, will
introduce governance and compliance changes.

A special committee of the Adviser's Board of Directors, comprised of the
members of the Adviser's Audit Committee and the other independent member of


ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 23


the Adviser's Board, directed and oversaw an internal investigation and a
comprehensive review of the facts and circumstances relevant to the SEC's and
the NYAG's investigations.

In addition, the Independent Directors of the Fund ("the Independent
Directors") have conducted an investigation of the above-mentioned matters with
the advice of an independent economic consultant and independent counsel.

On October 2, 2003, a purported class action complaint entitled Hindo, et al.
v. AllianceBernstein Growth & Income Fund, et al. ("Hindo Complaint") was filed
against the Adviser, Alliance Capital Management Holding L.P. ("Alliance
Holding"), Alliance Capital Management Corporation, AXA Financial, Inc., the
AllianceBernstein Funds, certain officers of the Adviser ("Alliance
defendants"), and certain other defendants not affiliated with the Adviser, as
well as unnamed Doe defendants. The Hindo Complaint was filed in the United
States District Court for the Southern District of New York by alleged
shareholders of two of the AllianceBernstein Funds. The Hindo Complaint alleges
that certain of the Alliance defendants failed to disclose that they improperly
allowed certain hedge funds and other unidentified parties to engage in "late
trading" and "market timing" of AllianceBernstein Fund securities, violating
Sections 11 and 15 of the Securities Act, Sections 10(b) and 20(a) of the
Exchange Act and Sections 206 and 215 of the Advisers Act. Plaintiffs seek an
unspecified amount of compensatory damages and rescission of their contracts
with the Adviser, including recovery of all fees paid to the Adviser pursuant
to such contracts.

Since October 2, 2003, 43 additional lawsuits making factual allegations
generally similar to those in the Hindo Complaint were filed in various federal
and state courts against the Adviser and certain other defendants. The
plaintiffs in such lawsuits have asserted a variety of theories for recovery
including, but not limited to, violations of the Securities Act, the Exchange
Act, the Advisers Act, the Investment Company Act, the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), certain state securities
laws and common law. All state court actions against the Adviser either were
voluntarily dismissed or removed to federal court. On February 20, 2004, the
Judicial Panel on Multidistrict Litigation transferred all actions to the
United States District Court for the District of Maryland (the "Mutual Fund
MDL").

On September 29, 2004, plaintiffs filed consolidated amended complaints with
respect to four claim types: mutual fund shareholder claims; mutual fund
derivative claims; derivative claims brought on behalf of Alliance Holding; and
claims brought under ERISA by participants in the Profit Sharing Plan for
Employees of the Adviser. All four complaints include substantially identical
factual allegations, which appear to be based in large part on the SEC Order
and the NYAG Order.


24 o ALLIANCEBERNSTEIN MID-CAP GROWTH FUND


On April 21, 2006, the Adviser and attorneys for the plaintiffs in the mutual
fund shareholder claims, mutual fund derivative claims, and ERISA claims
entered into a confidential memorandum of understanding ("MOU") containing
their agreement to settle these claims. The agreement will be documented by a
stipulation of settlement and will be submitted for court approval at a later
date. The derivative claims brought on behalf of Alliance Holding remain
pending.

On February 10, 2004, the Adviser received (i) a subpoena duces tecum from the
Office of the Attorney General of the State of West Virginia and (ii) a request
for information from West Virginia's Office of the State Auditor, Securities
Commission (the "West Virginia Securities Commissioner") (together, the
"Information Requests"). Both Information Requests require the Adviser to
produce documents concerning, among other things, any market timing or late
trading in the Adviser's sponsored mutual funds. The Adviser responded to the
Information Requests and has been cooperating fully with the investigation.

On April 11, 2005, a complaint entitled The Attorney General of the State of
West Virginia v. AIM Advisors, Inc., et al. ("WVAG Complaint") was filed
against the Adviser, Alliance Holding, and various other defendants not
affiliated with the Adviser. The WVAG Complaint was filed in the Circuit Court
of Marshall County, West Virginia by the Attorney General of the State of West
Virginia. The WVAG Complaint makes factual allegations generally similar to
those in the Hindo Complaint. On October 19, 2005, the WVAG Complaint was
transferred to the Mutual Fund MDL.

On August 30, 2005, the West Virginia Securities Commissioner signed a Summary
Order to Cease and Desist, and Notice of Right to Hearing addressed to the
Adviser and Alliance Holding. The Summary Order claims that the Adviser and
Alliance Holding violated the West Virginia Uniform Securities Act, and makes
factual allegations generally similar to those in the Commission Order and the
NYAGOrder. On January 26, 2006, the Adviser, Alliance Holding, and various
unaffiliated defendants filed a Petition for Writ of Prohibition and Order
Suspending Proceedings in West Virginia state court seeking to vacate the
Summary Order and for other relief. On April 12, 2006, respondents' petition
was denied. On May 4, 2006, respondents appealed the court's determination.

On June 22, 2004, a purported class action complaint entitled Aucoin, et al. v.
Alliance Capital Management L.P., et al. ("Aucoin Complaint") was filed against
the Adviser, Alliance Holding, Alliance Capital Management Corporation, AXA
Financial, Inc., AllianceBernstein Investment Research & Management, Inc.,
certain current and former directors of the AllianceBernstein Mutual Funds, and
unnamed Doe defendants. The Aucoin Complaint names certain of the
AllianceBernstein mutual funds as nominal defendants. The Aucoin Complaint was
filed in the United States District Court for the Southern District of New York
by alleged shareholders of an AllianceBernstein mutual fund. The Aucoin


ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 25


Complaint alleges, among other things, (i) that certain of the defendants
improperly authorized the payment of excessive commissions and other fees from
fund assets to broker-dealers in exchange for preferential marketing services,
(ii) that certain of the defendants misrepresented and omitted from
registration statements and other reports material facts concerning such
payments, and (iii) that certain defendants caused such conduct as control
persons of other defendants. The Aucoin Complaint asserts claims for violation
of Sections 34(b), 36(b) and 48(a) of the Investment Company Act, Sections 206
and 215 of the Advisers Act, breach of common law fiduciary duties, and aiding
and abetting breaches of common law fiduciary duties. Plaintiffs seek an
unspecified amount of compensatory damages and punitive damages, rescission of
their contracts with the Adviser, including recovery of all fees paid to the
Adviser pursuant to such contracts, an accounting of all fund-related fees,
commissions and soft dollar payments, and restitution of all unlawfully or
discriminatorily obtained fees and expenses.

Since June 22, 2004, nine additional lawsuits making factual allegations
substantially similar to those in the Aucoin Complaint were filed against the
Adviser and certain other defendants. All nine of the lawsuits (i) were brought
as class actions filed in the United States District Court for the Southern
District of New York, (ii) assert claims substantially identical to the Aucoin
Complaint, and (iii) are brought on behalf of shareholders of the Funds.

On February 2, 2005, plaintiffs filed a consolidated amended class action
complaint ("Aucoin Consolidated Amended Complaint") that asserts claims
substantially similar to the Aucoin Complaint and the nine additional lawsuits
referenced above. On October 19, 2005, the District Court dismissed each of the
claims set forth in the Aucoin Consolidated Amended Complaint, except for
plaintiffs' claim under Section 36(b) of the Investment Company Act. On January
11, 2006, the District Court granted defendants' motion for reconsideration and
dismissed the remaining Section 36(b) claim. On May 31, 2006 the District Court
denied plaintiffs' motion for leave to file an amended complaint. On July 5,
2006, plaintiffs filed a notice of appeal.

It is possible that these matters and/or other developments resulting from
these matters could result in increased redemptions of the AllianceBernstein
Mutual Funds' shares or other adverse consequences to the AllianceBernstein
Mutual Funds. This may require the AllianceBernstein Mutual Funds to sell
investments held by those funds to provide for sufficient liquidity and could
also have an adverse effect on the investment performance of the
AllianceBernstein Mutual Funds. However, the Adviser believes that these
matters are not likely to have a material adverse effect on its ability to
perform advisory services relating to the AllianceBernstein Mutual Funds.

Change of Independent Registered Public Accounting Firm

On June 14, 2006, KPMG LLP ("KPMG") was selected as the Fund's independent
registered public accounting firm for the 2006 fiscal year. A majority of the
Fund's Board of Directors, including a majority of the Independent Directors,
approved the appointment of KPMG LLP. The predecessor independent registered
public accounting firm's reports on the Fund's financial statements for the
year ended July 31, 2005 and the year ended July 31, 2004 contained no adverse
opinion or disclaimer of opinion and were not qualified or modified as to
uncertainty, audit scope or accounting principles. During such fiscal periods
there were no disagreements between the Fund and the predecessor independent
registered public accounting firm on any matter of accounting principles or
practices, financial statement disclosure, or auditing scope or procedures,
which such disagreements, if not resolved to the satisfaction of the
predecessor independent registered public accounting firm, would have caused
them to make reference to the subject matter of the disagreement in connection
with their reports on the financial statements for such periods.

NOTE L

Recent Accounting Pronouncement

On July 13, 2006, the Financial Accounting Standards Board ("FASB") released
FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" ("FIN
48"). FIN 48 provides guidance for how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in
the course of preparing the Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax positions not deemed to meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the current year. Adoption of
FIN 48 is required for fiscal years beginning after December 15, 2006 and is to
be applied to all open tax years as of the effective date. At this time,
management is evaluating the implications of FIN 48 and its impact in the
financial statements has not yet been determined.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders
AllianceBernstein Mid-Cap Growth Fund, Inc.

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of AllianceBernstein Mid-Cap Growth Fund, Inc. as
of July 31, 2006, and the related statement of operations, statement of changes
in net assets, and the financial highlights for the year then ended. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audit. The statement
of changes in net assets for the year ended July 31, 2005 and the financial
highlights for each of the presented years and periods ended prior to August 1,
2005 were audited by other independent registered public accountants whose
report thereon, dated September 16, 2005, expressed an unqualified opinion on
that financial statement and those financial highlights.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures
included confirmation of securities owned as of July 31, 2006, by
correspondence with the custodian and brokers or by other appropriate auditing
procedures. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
AllianceBernstein Mid-Cap Growth Fund, Inc. as of July 31, 2006, and the
results of its operations, changes in its net assets, and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 41


Information Regarding the Review and Approval of the Fund's Advisory Agreement

The Fund's disinterested directors (the "directors") unanimously approved the
continuance of the Advisory Agreement between the Fund and the Adviser at a
meeting held on June 14, 2006.

In preparation for the meeting, the directors had requested from the Adviser
and received and evaluated extensive materials, including performance and
expense information for other investment companies with similar investment
objectives as the Fund derived from data compiled by Lipper Inc. ("Lipper"),
which is not affiliated with the Adviser. The directors also reviewed an
independent evaluation from the Fund's Senior Officer (who is also the Fund's
Independent Compliance Officer) of the reasonableness of the advisory fees in
the Fund's Advisory Agreement (as contemplated by the September 2004 Assurance
of Discontinuance between the Adviser and the New York Attorney General)
wherein the Senior Officer concluded that such fees were reasonable. In
addition, the directors received a presentation from the Adviser and had an
opportunity to ask representatives of the Adviser various questions relevant to
the proposed approval. The directors noted that the Senior Officer's evaluation
considered the following factors: management fees charged to institutional and
other clients of the Adviser for like services; management fees charged by
other mutual fund companies for like services; cost to the Adviser and its
affiliates of supplying services pursuant to the Advisory Agreement, excluding
any intra-corporate profit; profit margins of the Adviser and its affiliates
from supplying such services; possible economies of scale as the Fund grows
larger; and nature and quality of the Adviser's services including the
performance of the Fund.

Prior to voting, the directors reviewed the proposed continuance of the
Advisory Agreement with management and with experienced counsel who are
independent of the Adviser and received a memorandum from such counsel
discussing the legal standards for their consideration of the proposed
continuance. The directors also discussed the proposed continuance in two
private sessions at which only the directors, their independent counsel and the
Fund's Independent Compliance Officer were present. In reaching their
determinations relating to continuance of the Advisory Agreement, the directors
considered all factors they believed relevant, including the following:

1.  information comparing the performance of the Fund to other investment
companies with similar investment objectives and to an index;

2.  the nature, extent and quality of investment, compliance, administrative
and other services rendered by the Adviser;

3.  payments received by the Adviser from all sources in respect of the Fund
and all investment companies in the AllianceBernstein Funds complex;

4.  the costs borne by, and profitability of, the Adviser and its affiliates in
providing services to the Fund and to all investment companies in the
AllianceBernstein Funds complex;

5.  comparative fee and expense data for the Fund and other investment
companies with similar investment objectives;

6.  the extent to which economies of scale would be realized to the extent the
Fund grows and whether fee levels reflect any economies of scale for the
benefit of investors;

7.  the Adviser's policies and practices regarding allocation of portfolio
transactions of the Fund, including the extent to which the Adviser benefits
from soft dollar arrangements;

8.  information about "revenue sharing" arrangements that the Adviser has
entered into in respect of the Fund;

9.  portfolio turnover rates for the Fund compared to other investment
companies with similar investment objectives;

10.  fall-out benefits that the Adviser and its affiliates receive from their
relationships with the Fund;

11.  information about fees charged by the Adviser to other clients with a
substantially similar investment style as the Fund;

12.  the Senior Officer's evaluation of the reasonableness of the fee payable
to the Adviser in the Advisory Agreement;

13.  the professional experience and qualifications of the Fund's portfolio
management team and other senior personnel of the Adviser; and

14.  the terms of the Advisory Agreement.

The directors also considered their knowledge of the nature and quality of the
services provided by the Adviser to the Fund gained from their experience as
directors or trustees of most of the registered investment companies advised by
the Adviser, their overall confidence in the Adviser's integrity and competence
they have gained from that experience and the Adviser's responsiveness to
concerns raised by them in the past, including the Adviser's willingness to
consider

and implement organizational and operational changes designed to improve
investment results and the services provided to the AllianceBernstein Funds.

In their deliberations, the directors did not identify any particular
information that was all-important or controlling, and different directors may
have attributed different weights to the various factors.

The directors determined that the overall arrangements between the Fund and the
Adviser, as provided in the Advisory Agreement, were fair and reasonable in
light of the services performed, expenses incurred and such other matters as
the directors considered relevant in the exercise of their business judgment.

The material factors and conclusions that formed the basis for the directors
reaching their determinations to approve the continuance of the Advisory
Agreement (including their determinations that the Adviser should continue to
be the investment adviser for the Fund, and that the fees payable to the
Adviser pursuant to the Advisory Agreement are appropriate) were separately
discussed by the directors.

Nature, extent and quality of services provided by the Adviser

The directors noted that, under the Advisory Agreement, the Adviser, subject to
the control of the directors, administers the Fund's business and other
affairs. The Adviser manages the investment of the assets of the Fund,
including making purchases and sales of portfolio securities consistent with
the Fund's investment objective and policies. Under the Advisory Agreement, the
Adviser also provides the Fund with such office space, administrative and other
services (exclusive of, and in addition to, any such services provided by any
others retained by the Fund) and executive and other personnel as are necessary
for the Fund's operations. The Adviser pays all of the compensation of
directors of the Fund who are affiliated persons of the Adviser and of the
officers of the Fund.

The directors also considered that the Advisory Agreement provides that the
Fund will reimburse the Adviser for the cost of certain clerical, accounting,
administrative and other services provided at the Fund's request by employees
of the Adviser or its affiliates. Requests for these "at no more than cost"
reimbursements are approved by the directors on a quarterly basis and (to the
extent requested and paid) result in a higher rate of total compensation from
the Fund to the Adviser than the fee rates stated in the Fund's Advisory
Agreement.

The directors considered the scope and quality of services provided by the
Adviser under the Advisory Agreement and noted that the scope of services
provided by advisers of funds had expanded over time as a result of regulatory
and other developments. The directors noted, for example, that the Adviser is
responsible for maintaining and monitoring its own and, to varying degrees, the
Fund's compliance programs, and that these compliance programs have recently


44 o ALLIANCEBERNSTEIN MID-CAP GROWTH FUND


been refined and enhanced in light of new regulatory requirements. The
directors considered the quality of the in-house investment research
capabilities of the Adviser and the other resources it has dedicated to
performing services for the Fund. The quality of administrative and other
services, including the Adviser's role in coordinating the activities of the
Fund's other service providers, also were considered. The directors also
considered the Adviser's response to recent regulatory compliance issues
affecting a number of the investment companies in the AllianceBernstein Funds
complex. The directors concluded that, overall, they were satisfied with the
nature, extent and quality of services provided to the Fund under the Advisory
Agreement.

Costs of Services Provided and Profitability to the Adviser

The directors reviewed a schedule of the revenues, expenses and related notes
indicating the profitability of the Fund to the Adviser for calendar years 2004
and 2005 that had been prepared with an updated expense allocation methodology.
The directors noted that the updated methodology differed in various respects
from the methodology used in prior years. The directors reviewed the
assumptions and methods of allocation used by the Adviser in preparing
fund-specific profitability data, and noted the Adviser's representation to
them that it believed that the methods of allocation used in preparing the
profitability information were reasonable and appropriate and that the Adviser
had previously discussed with the directors that there is no generally accepted
allocation methodology for information of this type.

The directors recognized that it is difficult to make comparisons of
profitability from fund advisory contracts because comparative information is
not generally publicly available and is affected by numerous factors, including
the structure of the particular adviser, the types of funds it manages, its
business mix, numerous assumptions regarding allocations and the adviser's
capital structure and cost of capital. In considering profitability
information, the directors considered the effect of fall-out benefits on the
Adviser's expenses, as well as the "revenue sharing" arrangements the Adviser
has entered into with certain entities that distribute shares of the Fund. The
directors focused on the profitability of the Adviser's relationship with the
Fund before taxes and distribution expenses. The directors recognized that the
Adviser should generally be entitled to earn a reasonable level of profits for
the services it provides to the Fund and, based on their review, concluded that
they were satisfied that the Adviser's level of profitability from its
relationship with the Fund was not excessive.

Fall-Out Benefits

The directors considered that the Adviser benefits from soft dollar
arrangements whereby it receives brokerage and research services from many of
the brokers and dealers that execute purchases and sales of securities on
behalf of its clients on an agency basis. They noted that the Adviser makes
presentations to the directors regarding its trading practices and brokerage
allocation policies, including its


ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 45


policies with respect to soft dollar arrangements, from time to time and had
made a special presentation to the directors in May 2006 on this subject. The
directors noted that the Adviser has represented to them that all of its soft
dollar arrangements are consistent with applicable legal requirements including
the achievement of best execution.

The directors also considered that the Distributor, which is a wholly-owned
subsidiary of the Adviser, receives 12b-1 fees from the Fund in respect of
classes of shares of the Fund that are subject to the Fund's 12b-1 plan and
retains a portion of such 12b-1 fees, and receives all or a portion of the
sales charges on sales or redemptions of certain classes of shares. The
directors also noted that certain affiliates of the Adviser distribute shares
of the Fund and receive compensation in that connection, that a subsidiary of
the Adviser provides transfer agency services to the Fund and receives
compensation from the Fund for such services, and that brokers who are
affiliated with the Adviser are permitted to execute brokerage transactions for
the Fund subject to satisfaction of certain requirements and receive brokerage
commissions from the Fund and liquidity rebates from electronic communication
networks ("ECNs") in connection with certain of such transactions. The
directors noted that the Adviser had made a recent presentation to the
directors detailing liquidity rebates that Sanford C. Bernstein & Co. LLC
receives in respect of transactions effected through ECNs.

The directors recognized that the Adviser's profitability would be somewhat
lower if it did not receive research for soft dollars or if the Adviser's
affiliates did not receive the other benefits described above. The directors
understood that the Adviser also might derive reputational and other benefits
from its association with the Fund.

Investment Results

In addition to the information reviewed by the directors in connection with the
meeting, the directors receive detailed comparative performance information for
the Fund at each regular Board meeting during the year. At the meeting, the
directors reviewed information from a report prepared by Lipper showing
performance of the Class A Shares of the Fund as compared to a group of 15 to 8
funds (depending on the year) in its Lipper category selected by Lipper (the
"Performance Group") and as compared to a universe of 116 to 39 funds
(depending on the year) in its Lipper category selected by Lipper (the
"Performance Universe") for periods ended December 31, 2005 over the 1-, 3, 5-
and 10-year periods. The directors also reviewed information prepared by the
Adviser showing performance of the Class A Shares of the Fund as compared to
the Russell MidCap Growth Index (the "Index") for periods ended December 31,
2005 over the 1-, 3-, 5- and 10-year periods. The directors noted that in the
Performance Group comparison the Fund was in the 4th quintile in the 1- and
10-year periods and 1st quintile in the 3- and 5-year periods, and in the
Performance Universe comparison the Fund was in the 4th quintile in the 1- and


46 o ALLIANCEBERNSTEIN MID-CAP GROWTH FUND


10-year periods, 1st quintile in the 3-year period and 2nd quintile in the
5-year period. The comparative information showed that the Fund underperformed
the Index in the 1- and 10-year periods and outperformed the Index in the 3-
and 5-year periods. No comparative information was available for the since
inception period (July 1938 inception). Based on their review and their
discussion of the reasons for the Fund's recent underperformance with the
Adviser, the directors retained confidence in the Adviser's ability to continue
to advise the Fund and concluded that the Fund's investment performance was
understandable. The directors informed the Adviser that they planned to closely
monitor the Fund's performance.

Advisory Fees and Other Expenses

The directors considered the advisory fee rate paid by the Fund to the Adviser
and information prepared by Lipper concerning fee rates paid by other funds in
the same Lipper category as the Fund at a common asset level. The directors
recognized that it is difficult to make comparisons of advisory fees because
there are variations in the services that are included in the fees paid by
other funds.

The directors also considered the fees the Adviser charges other clients with
investment objectives similar to those of the Fund. For this purpose, they
reviewed information in the Adviser's Form ADV and a chart prepared by the
Adviser disclosing the institutional fee schedule for institutional products
that have a substantially similar investment style as the Fund. They had
previously received an oral presentation from the Adviser that supplemented
such information. The directors noted that the institutional fee schedule for
clients with a substantially similar investment style as the Fund had much
lower breakpoints than the fee schedule in the Fund's Advisory Agreement. The
directors also noted that the application of such fee schedule to the level of
assets of the Fund would result in a fee rate that would be significantly lower
than that in the Fund's Advisory Agreement. The directors noted that the
Adviser may, in some cases, negotiate fee rates with large institutional
clients that are lower than those reviewed by the directors and that they had
previously discussed with the Adviser its policies in respect of such
negotiated arrangements. The directors also reviewed information that indicated
that the Adviser sub-advises a registered investment company that has
investment strategies similar to the Fund at lower fee rates than those paid by
the Fund.

The Adviser reviewed with the directors the significant differences in the
scope of services it provides to institutional clients and sub-advised funds
and to the Fund. For example, the Advisory Agreement requires the Adviser to
provide, in addition to investment advice, office facilities and officers
(including officers to provide required certifications). The Adviser also
coordinates the provision of services to the Fund by non-affiliated service
providers and is responsible for the compensation of the Fund's Independent
Compliance Officer and certain related expenses. The provision of these
non-advisory services involves costs and expo


ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 47


sure to liability. The Adviser explained that many of these services normally
are not provided to non-investment company clients or to investment company
clients when the Adviser acts in a pure sub-advisory capacity, and that fees
charged to the Fund reflect the costs and risks of the additional obligations.
The Adviser also noted that since the Fund is constantly issuing and redeeming
its shares, it is more difficult to manage than an institutional account, where
the assets are relatively stable. In light of these facts, the directors did
not place significant weight on these fee comparisons.

The directors also considered the total expense ratio of the Class A shares of
the Fund in comparison to the fees and expenses of funds within two comparison
groups created by Lipper: an Expense Group and an Expense Universe. Lipper
described an Expense Group as a representative sample of comparable funds and
an Expense Universe as a broader group, consisting of all funds in the
investment classification/objective with a similar load type as the Fund. The
Class A expense ratio of the Fund was based on the Fund's latest fiscal year
expense ratio. The directors recognized that the expense ratio information for
the Fund potentially reflected on the Adviser's provision of services, as the
Adviser is responsible for coordinating services provided to the Fund by
others. The directors noted that it was likely that the expense ratios of some
funds in the Fund's Lipper category also were lowered by waivers or
reimbursements by those funds' investment advisers, which in some cases were
voluntary and perhaps temporary.

The directors noted that the Fund's at approximate current size contractual
effective fee rate of 70.7 basis points was materially lower than the Expense
Group median. The directors noted that the latest fiscal year administrative
expense reimbursement by the Fund pursuant to the Advisory Agreement was 1
basis point, and that as a result the total compensation received by the
Adviser from the Fund pursuant to the Advisory Agreement was only somewhat
lower than the Expense Group median. The directors noted that the Fund's total
expense ratio was slightly lower than the Expense Group median and materially
lower than the Expense Universe median. The directors concluded that the Fund's
expense ratio was satisfactory.

Economies of Scale

The directors noted that the advisory fee schedule for the Fund contains
breakpoints so that, if assets were to increase over the breakpoint levels, the
fee rates would be reduced on the incremental assets. The directors also
considered a presentation by an independent consultant discussing economies of
scale issues in the mutual fund industry. The directors believe that economies
of scale are realized (if at all) by the Adviser across a variety of products
and services, and not only in respect of a single fund. The directors noted
that there is no uniform methodology for establishing breakpoints that give
effect to fund-specific services provided by the Adviser and to the economies
of scale that the Adviser may realize in its overall mutual fund business or
those components of it which


48 o ALLIANCEBERNSTEIN MID-CAP GROWTH FUND


directly or indirectly affect the Fund's operations. The directors observed
that in the mutual fund industry as a whole, as well as among funds similar to
the Fund, there is no uniformity or pattern in the fees and asset levels at
which breakpoints (if any) apply. Depending on the age and size of a particular
fund and its adviser's cost structure, different conclusions can be drawn as to
whether there are economies of scale to be realized at any particular level of
assets, notwithstanding the intuitive conclusion that such economies exist, or
will be realized at some level of total assets. Moreover, because different
advisers have different cost structures and service models, it is difficult to
draw meaningful conclusions from the comparison of a fund's advisory fee
breakpoints with those of comparable funds. The directors also noted that the
advisory agreements for many funds do not have breakpoints at all. Having taken
these factors into account, the directors concluded that the Fund's breakpoint
arrangements would result in a sharing of economies of scale in the event of a
very significant increase in the Fund's net assets.

THE FOLLOWING IS NOT PART OF THE SHAREHOLDER REPORT OR THE FINANCIAL STATEMENTS

SUMMARY OF SENIOR OFFICER'S EVALUATION OF INVESTMENT ADVISORY AGREEMENT(1)

The following is a summary of the evaluation of the Investment Advisory
Agreement between AllianceBernstein L.P. (the "Adviser") and AllianceBernstein
Mid-Cap Growth Fund, Inc. (the "Fund"), prepared by Philip L. Kirstein, the
Senior Officer of the Fund for the Directors of the Fund, as required by an
August 2004 agreement between the Adviser and the New York State Attorney
General (the "NYAG").(2) The Senior Officer's evaluation of the Investment
Advisory Agreement is not meant to diminish the responsibility or authority of
the Board of Directors of the Fund to perform its duties pursuant to Section 15
of the Investment Company Act of 1940 (the "40 Act") and applicable state law.
The purpose of the summary is to provide shareholders with a synopsis of the
independent evaluation of the reasonableness of the advisory fees proposed to
be paid by the Fund which was provided to the Directors in connection with
their review of the proposed approval of the continuance of the Investment
Advisory Agreement. The Senior Officer's evaluation considered the following
factors:

1.  Management fees charged to institutional and other clients of the Adviser
for like services;

2.  Management fees charged by other mutual fund companies for like services;

3.  Costs to the Adviser and its affiliates of supplying services pursuant to
the advisory agreement, excluding any intra-corporate profit;

4.  Profit margins of the Adviser and its affiliates from supplying such
services;


5.  Possible economies of scale as the Fund grows larger; and

6.  Nature and quality of the Adviser's services including the performance of
the Fund.


(1)  It should be noted that the information in the fee summary was completed
on June 2, 2006 and presented to the Board of Directors on June 14, 2006 in
accordance with the Assurance of Discontinuance between the NYAG and the
Adviser. It also should be noted that references in the fee summary pertaining
to performance and expense ratios refer to Class A shares of the Fund.

(2)  Future references to the Fund do not include "AllianceBernstein."

I. MANAGEMENT FEES CHARGED TO INSTITUTIONAL AND OTHER CLIENTS

The management fees charged to investment companies which the Adviser manages
and sponsors are normally higher than those charged to similar sized
institutional accounts, including pension plans and sub-advised investment
companies. The fee differential reflects, among other things, different
services provided to such clients, and different liabilities assumed. Services
provided by the Adviser to the Fund that are not provided to non-investment
company clients include providing office space and personnel to serve as Fund
Officers, who


(3)  The Fund's fee schedule was not amended in connection with the Adviser's
settlement with the NYAG in December 2003 since the Fund's fee schedule already
had lower breakpoints than the NYAG related fee schedule for AllianceBernstein
Mutual Funds with a "Growth" category.

(4)  Annualized.


ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 51


among other responsibilities make the certifications required under the
Sarbanes-Oxley Act of 2002, and coordinating with and monitoring the Fund's
third party service providers such as Fund counsel, auditors, custodians,
transfer agents and pricing services. The accounting, administrative, legal and
compliance requirements for the Fund are more costly than those for
institutional assets due to the greater complexities and time required for
investment companies, although as previously noted, a portion of these expenses
is reimbursed by the Fund to the Adviser. Also, retail mutual funds managed by
the Adviser are widely held. Servicing the Fund's investors is more time
consuming and labor intensive compared to institutional clients since the
Adviser needs to communicate with a more extensive network of financial
intermediaries and shareholders. In addition, managing the cash flow of an
investment company may be more difficult than that of a stable pool of assets,
such as an institutional account with little cash movement in either direction,
particularly, if the Fund is in net redemption and the Adviser is frequently
forced to sell securities to raise cash for redemptions. However, managing a
fund with positive cash flow may be easier at times than managing a stable pool
of assets. Finally, in recent years, investment advisers have been sued by
institutional clients and have suffered reputational damage both by the
attendant publicity and outcomes other than complete victories. Accordingly,
the legal and reputational risks associated with institutional accounts are
greater than previously thought, although still not equal to those related to
the mutual fund industry.

Notwithstanding the Adviser's view that managing an investment company is not
comparable to managing other institutional accounts because the services
provided are different, it is worth considering information regarding the
advisory fees charged to institutional accounts with a substantially similar
investment style as the Fund. It should be noted that the Adviser has indicated
that with respect to institutional accounts with assets greater than $300
million, it will negotiate a fee schedule. Discounts that are negotiated vary
based upon each client relationship. In addition to the AllianceBernstein
Institutional fee schedule, set forth below is what would have been the
effective advisory fee of the Fund had the AllianceBernstein Institutional fee
schedule been applicable to the Fund versus the Fund's advisory fee:

additional discussion.


52 o ALLIANCEBERNSTEIN MID-CAP GROWTH FUND


The Adviser provides sub-advisory investment services to certain other
investment companies managed by other fund families. The Adviser charges the
following fee for the sub-advised fund that has a similar investment style as
the Fund:

Fund                           Sub-advised Fund           Fee Schedule
- -------------------------------------------------------------------------------
Mid-Cap Growth Fund, Inc.         Client # 1       0.75% on first $10 million
                                                   0.625% on next $10 million
                                                   0.50% on next $20 million
                                                   0.375% on next $20 million
                                                   0.25% thereafter

It is fair to note that the services the Adviser provides pursuant to
sub-advisory agreements are generally confined to the services related to the
investment process; in other words, they are not as comprehensive as the
services provided to the Fund by the Adviser.

II. MANAGEMENT FEES CHARGED BY OTHER MUTUAL FUND COMPANIES FOR LIKE SERVICES.

Lipper, Inc. ("Lipper"), an analytical service that is not affiliated with the
Adviser, compared the fees charged to the Fund with fees charged to other
investment companies for similar services by other investment advisers.
Lipper's analysis included the Fund's ranking with respect to the proposed
management fee relative to the Lipper group median at the approximate current
asset level of the Fund.(6)

                                   Effective         Lipper
                                  Management         Group

Mid-Cap Growth Fund, Inc.           0.707            0.790            7/15


(6)  The effective management fee is calculated by Lipper using the Fund's
contractual management fee rate at a hypothetical asset level. The hypothetical
asset level is based on the combined net assets of all classes of the Fund,
rounded up to the next $25 million. Lipper's total expense ratio information is
based on the most recent annual report except as otherwise noted. A ranking of
"1" means that the Fund has the lowest effective fee rate in the Lipper peer
group.

(7)  The effective management fee rate for the Fund does not reflect the
aforementioned payments made by the Fund to the Adviser for certain clerical,
legal, accounting, administrative, and other services.


ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 53


Lipper also analyzed the total expense ratio of the Fund in comparison to its
Lipper Expense Group(8) and Lipper Expense Universe.(9) Lipper describes a
Lipper Expense Group as a representative sample of comparable funds and a
Lipper Expense Universe as a broader group, consisting of all funds in the same
investment classification/objective with a similar load type as the subject
Fund. The result of that analysis is set forth below:

                                          Lipper   Lipper    Lipper     Lipper
                             Expense      Group     Group   Universe   Universe
Fund                      Ratio(%)(10)  Median(%)   Rank    Median(%)    Rank

Mid-Cap Growth Fund, Inc.    1.251       1.297      6/15      1.398      21/93

Based on this analysis, the Fund has a more favorable ranking on a total
expense ratio basis than it does on a management fee basis.

III. COSTS TO THE ADVISER AND ITS AFFILIATES OF SUPPLYING SERVICES PURSUANT TO
THE MANAGEMENT FEE ARRANGEMENT, EXCLUDING ANY INTRA-CORPORATE PROFIT.

A consultant was retained by the Senior Officer to work with the Adviser's
personnel to align the Adviser's two profitability reporting systems. The
alignment, which now has been completed, allows the Adviser's management and
the Directors to receive consistent presentations of the financial results and
profitability although the two profitability reporting systems operate
independently. See Section IV for additional discussion.

IV. PROFIT MARGINS OF THE ADVISER AND ITS AFFILIATES FOR SUPPLYING SUCH
SERVICES.

The profitability information for the Fund prepared by the Adviser for the
Board of Directors was reviewed by the Senior Officer. The Adviser's
profitability from providing investment advisory services to the Fund increased
during calendar year 2005 relative to 2004.

In addition to the Adviser's direct profits from managing the Fund, certain of
the Adviser's affiliates have business relationships with the Fund and may earn
a profit from providing other services to the Fund. The courts have referred to
this type of business opportunity as "fall-out benefits" to the Adviser and
indicated


(8)  Lipper uses the following criteria in screening funds to be included in
the Fund's expense group: fund type, investment classification/objective, load
type and similar 12b-1/non-12b-1 service fees, asset (size) comparability, and
expense components and attributes. A Lipper Expense Group will typically
consist of seven to twenty funds.

(9)  Except for asset (size) comparability, Lipper uses the same criteria for
selecting a Lipper Expense Group when selecting a Lipper Expense Universe.
Unlike the Lipper Expense Group, the Lipper Expense Universe allows for the
same adviser to be represented by more than just one fund.

(10)  The total expense ratio shown is for the Fund's Class A shares.

that they should be factored into the evaluation of the total relationship
between the Fund and the Adviser. Neither case law nor common business practice
precludes the Adviser's affiliates from earning a reasonable profit on this
type of relationship. These affiliates provide transfer agent, distribution,
and brokerage related services to the Fund and receive transfer agent fees,
Rule 12b-1 payments, front-end sales loads, contingent deferred sales charges
("CDSC") and commissions for providing brokerage services. In addition, the
Adviser benefits from soft dollar arrangements which offset expenses the
Adviser would otherwise incur. Additional information regarding distribution
related fees can be found in the prospectus of the Fund.

AllianceBernstein Investments, Inc. ("ABI"), an affiliate of the Adviser, is
the Fund's principal underwriter. ABI and the Adviser have disclosed in the
Fund's prospectus that they may make revenue sharing payments from their own
resources, in addition to resources derived from sales loads and Rule 12b-1
fees, to firms that sell shares of the Fund. In 2005, ABI paid approximately
0.042% of the average monthly assets of the AllianceBernstein Mutual Funds or
approximately $18.0 million for distribution services and educational support
(revenue sharing payments). For 2006, it is anticipated, ABI will pay
approximately 0.04% of the average monthly assets of the AllianceBernstein
Mutual Funds or approximately $17.5 million.(11)

After payments to third party intermediaries, ABI retained the following
amounts for Class A front-end load sales charges from sales of the Fund's Class
A shares during the Fund's most recently completed fiscal year:

Fund                                                        Amount Received
- -------------------------------------------------------------------------------
Mid-Cap Growth Fund, Inc.                                        $13,103

ABI received the amounts set forth below in Rule 12b-1 fees and CDSC for the
Fund during the Fund's most recent fiscal year:

Fund                                12b-1 Fees Received       CDSC Received
- -------------------------------------------------------------------------------
Mid-Cap Growth Fund, Inc.                $2,369,036             $106,942

Fees and reimbursements for out of pocket expenses charged by AllianceBernstein
Investor Services, Inc. ("ABIS"), the affiliated transfer agent, are based on
the level of the network account and the class of share held by the account.
ABIS also receives a fee per shareholder sub-account for each account
maintained by an intermediary on an omnibus basis. ABIS' after-tax
profitability

pays the incremental costs associated with the mailing. The incremental cost is
less than what an "independent mailing" would cost.

increased in 2005 in comparison to 2004. ABIS received the following fee from
the Fund in the most recent fiscal year:

Fund                                                         ABIS Fee(12)
- -------------------------------------------------------------------------------
Mid-Cap Growth Fund, Inc.                                    $1,140,662

The Fund effected brokerage transactions through the Adviser's affiliate,
Sanford C. Bernstein & Co. LLC ("SCB & Co.") and/or its U.K. affiliate, Sanford
C. Bernstein Limited ("SCB Ltd."), collectively "SCB," and paid commissions for
such transactions during the Fund's most recently completed fiscal year. The
Adviser represented that SCB's profitability from business conducted with the
Fund is comparable to the profitability of SCB's dealings with other similar
third party clients. In the ordinary course of business, SCB receives and pays
liquidity rebates from electronic communications networks ("ECNs") derived from
trading for its clients, including the Fund. These credits and charges are not
being passed on to any SCB client. The Adviser also receives certain soft
dollar benefits from brokers that execute agency trades for the Fund and other
clients. These soft dollar benefits reduce the Adviser's cost of doing business
and increase its profitability.

V. POSSIBLE ECONOMIES OF SCALE

The Adviser has indicated that the breakpoints in the fee schedule in the
Investment Advisory Agreement reflect a sharing of economies of scale to the
extent the breakpoints are reached. Based on some of the professional
literature that has considered economies of scale in the mutual fund industry
it is thought that to the extent economies of scale exist, they may more often
exist across a fund family as opposed to a specific fund. This is because the
costs incurred by the Adviser, such as investment research or technology for
trading or compliance systems can be spread across a greater asset base as the
fund family increases in size. It is also possible that as the level of
services required to operate a successful investment company has increased over
time, and advisory firms have made such investments in their business to
provide improved services, there may be a sharing of economies of scale without
a reduction in advisory fees.

An independent consultant made a presentation to the Board of Directors and the
Senior Officer regarding possible economies of scale or scope in the mutual
fund industry. Based on the presentation, it was evident that fund management
companies benefit from economies of scale. However, due to lack of cost data,
researchers had to infer facts about the costs from the behavior of fund
expenses; there was a lack of consensus among researchers as to whether
economies of scale were being passed on to the shareholders. It is contemplated
that additional work


(12)  The fee disclosed is net of any waivers or any other expense offset
arrangement with ABIS. An expense offset is created by the interest earned on
the positive cash balance that occurs within the transfer agent account as
there is a one day lag with regards to money movement from the shareholder's
account to the transfer agent's account and then from the transfer agent's
account to the Fund's account.

will be performed to determine if the benefits of economies of scale or scope
are being passed to shareholders by the Adviser. In the meantime, it is clear
that to the extent a fund's assets exceeds its initial breakpoint its
shareholders benefit from a lower fee rate.

VI. NATURE AND QUALITY OF THE ADVISER'S SERVICES INCLUDING THE PERFORMANCE OF
THE FUND.

With assets under management of $635 billion as of April 30, 2006, the Adviser
has the investment experience to manage and provide non-investment services
(described in Section I) to the Fund.

The information below, prepared by Lipper, shows the 1, 3, 5 and 10 year
performance ranking of the Fund(13) relative to its Lipper Performance
Group(14) and Lipper Performance Universe(15) for the periods ended December
31, 2005:

CONCLUSION:

Based on the factors discussed above the Senior Officer's conclusion is that
the proposed fee for the Fund is reasonable and within the range of what would
have been negotiated at arms-length in light of all the surrounding
circumstances. This conclusion in respect of the Fund is based on an evaluation
of all of these factors and no single factor was dispositive.

Dated: July 17, 2006

for periods through December 31, 2005 in order to maintain consistency with
Lipper's performance rankings in the analysis.
