EATON VANCE TAX-MANAGED SMALL-CAP GROWTH FUND 1.2 AS OF OCTOBER 31, 2003
LETTER TO SHAREHOLDERS

[PHOTO OF THOMAS E. FAUST JR.]
Thomas E. Faust Jr.
President

Eaton Vance Tax-Managed Small-Cap Growth Fund 1.2, Class A shares, had a total
return of 25.97% during the year ended October 31, 2003. That return was the
result of an increase in net asset value (NAV) per share from $6.20 on October
31, 2002, to $7.81 on October 31, 2003.(1) Class B shares had a total return of
25.16% for the same period, the result of an increase in NAV from $6.12 to
$7.66.(1) Class C shares had a total return of 25.16% for the same period, the
result of an increase in NAV from $6.12 to $7.66.(1) Additional information
about the Fund's performance (including after-tax performance) appears on page
6.

By comparison, the S&P SmallCap 600 Index - a widely recognized, unmanaged index
of small-capitalization stocks - had a total return of 33.58% for the one-year
period from October 31, 2002, to October 31, 2003.(2)

A CLOSER LOOK AT THE JOBS AND GROWTH TAX RELIEF RECONCILIATION ACT OF 2003...

In May of this year, Congress passed legislation that included several
provisions that affect individual investors. The most important aspects of the
Jobs and Growth Tax Relief Reconciliation Act of 2003 for individuals are a
lowering of tax rates for ordinary income and long-term capital gains and a
change in the tax treatment of qualifying dividend income, which is now taxed at
the same rates as long-term capital gains, rather than as ordinary income.

The biggest change for equity investors is that qualifying dividend income is
now taxed at much lower rates than other investment income and short-term gains
(maximum rate of 15% vs. 35%). The spread between short-term and long-term
capital gains tax rates has also increased. These changes increase the
importance of achieving a mix of returns that emphasizes long-term gains and
qualifying dividends over less favorably taxed short-term gains and
non-qualifying dividends and other investment income. Deferring taxes on
long-term gains continues to be of significant value, particularly for investors
with longer time horizons and for assets earmarked for inheritance.

WITH TODAY'S LOWER TAX RATES, IT IS STILL IMPORTANT FOR INVESTORS TO CONSIDER
TAX EFFECTS...

Taxes continue to be the single largest cost borne by long-term equity
investors. Strategies to minimize tax effects can add substantial value to
taxable accounts without sacrificing performance or adding to portfolio risk.
Just as before, it makes sense for taxpayers to invest in funds that share their
objective of after-tax returns.

                                        Sincerely,

                                        /s/ Thomas E. Faust Jr.

EATON VANCE TAX-MANAGED SMALL-CAP GROWTH FUND 1.2 AS OF OCTOBER 31, 2003
MANAGEMENT DISCUSSION

AN INTERVIEW WITH TONI SHIMURA, VICE PRESIDENT AND PORTFOLIO MANAGER OF
TAX-MANAGED SMALL-CAP GROWTH PORTFOLIO

[PHOTO OF TONI SHIMURA]
Toni Shimura
Portfolio Manager

Q: WHAT WAS THE OVERALL MARKET ENVIRONMENT FOR THE PORTFOLIO FOR THE YEAR ENDING
   OCTOBER 31, 2003?

A: The stock market environment for small capitalization stocks, and small-cap
   growth stocks in particular, was a positive one, much improved from the prior
   year. We believe the market was strong for several reasons. First, fiscal
   policy was favorable, with taxes on dividends and capital gains reduced to
   their lowest levels in 60 years. Secondly, monetary policy was favorable as
   well, with the Federal Reserve keeping interest rates low. This helped pave
   the way for a slow and steady recovery in the economy, and with it,
   improvements in the earnings of many of the companies in the Portfolio.

</Table>

+ Sector positions subject to change due to active management.

Q: CAN YOU GIVE THE SHAREHOLDERS A SUMMARY OF THE FUND'S PERFORMANCE OVER THE
   LAST YEAR?

A: We are pleased to report that the Fund had a solid return of 25.97% for the
   12 months ended October 31, 2003 (for Class A shares at NAV). This return
   beat the broad market, as measured by the S&P 500 Index, which returned
   20.79%, but underperformed its benchmark, the S&P SmallCap 600 Index, which
   had a total return of 33.58% for the period.*


Q: WHAT FACTORS ACCOUNTED FOR THE FUND'S PERFORMANCE RELATIVE TO THE BENCHMARK
   DURING THE PERIOD?

A: The Fund's return in 2003 trailed that of the S&P 600 SmallCap Index
   primarily due to the very strong performance of many low-priced,
   micro-capitalization companies included in that index.* These stocks included
   micro-cap technology and biotech stocks that had very high returns. Not
   owning those stocks hurt our performance relative to our small-cap benchmark.
   The Portfolio also held some underperforming stocks early in the fiscal year
   that negatively affected our performance.


Q: WHAT INDUSTRY GROUPS MOST NEGATIVELY IMPACTED FUND PERFORMANCE OVER THE PAST
   12 MONTHS?

A: As a group, the Portfolio's health care stocks were the worst performers,
   both on an absolute basis and relative to the S&P SmallCap 600 Index.* The
   weakened financial condition of hospitals resulted in a slowdown in purchases
   of non-essential information technology services and medical devices.

*  It is not possible to invest directly in an Index.

Q: WHAT STOCKS AND INDUSTRY GROUPS MOST POSITIVELY IMPACTED FUND PERFORMANCE
   OVER THE PAST 12 MONTHS?

A: The technology sector was the best performing sector of the stock market over
   the past year and, likewise, was the best performing sector of the Portfolio.
   The Portfolio's technology stocks advanced an average of 47% over the past 12
   months. While that was a large increase, the Portfolio's technology holdings
   lagged the 60% advance in the S&P SmallCap 600 technology sector overall,
   because we were underweighted in some of those micro-cap stocks I mentioned
   earlier.* However, the Portfolio was overweighted in the technology-related
   sector, particularly in semiconductors and software, which helped our
   performance. Many of these companies had performed poorly in the market
   declines of recent years and benefited from the economic rebound.

   Two other unrelated sub-sectors that contributed positively to performance
   were telecommunications services stocks and specialty retailers. This latter
   group included some solid performers who were growing their earnings through
   strong comparable store sales and new store openings. Specialty retail
   holdings that made positive contributions included Urban Outfitters (an urban
   lifestyle retailer) and Tractor Supply (a retailer catering to part-time
   farmers).


Q: DO YOU ANTICIPATE ANY SIGNIFICANT CHANGES TO YOUR INVESTMENT STRATEGY FOR THE
   PORTFOLIO?

A: Although the Portfolio had a change in portfolio manager this year, there has
   been no significant alteration of its strategy, a strategy that we believe
   still offers investors an opportunity for long-term, after-tax returns. We
   believe that successful investing requires broad diversification, a long-term
   orientation and an emphasis on companies that are reasonably priced in
   relation to their fundamental value. We continue to maintain a broadly
   diversified Portfolio from an individual stock and sector standpoint.


Q: DO YOU HAVE ANY FINAL COMMENTS FOR OUR SHAREHOLDERS ON YOUR OUTLOOK GOING
   FORWARD?

A: Many of the companies held by the Portfolio have had positive fundamentals
   despite the uneven economy of the past few years. We believe that the broad
   market is now recognizing these strong fundamentals. We believe that many of
   the companies held by the Portfolio, especially those in technology, business
   services, and specialty retail, are especially well positioned to benefit
   from an acceleration in economic activity. In the year to come, we will
   continue to seek out small-cap growth companies that we believe can
   demonstrate earnings growth rates that exceed those of other publicly-traded
   companies.


   THE VIEWS EXPRESSED IN THIS REPORT ARE THOSE OF THE PORTFOLIO MANAGER AND ARE
   CURRENT ONLY THROUGH THE END OF THE PERIOD OF THE REPORT AS STATED ON THE
   COVER. THESE VIEWS ARE SUBJECT TO CHANGE AT ANY TIME BASED UPON MARKET OR
   OTHER CONDITIONS, AND EATON VANCE DISCLAIMS ANY RESPONSIBILITY TO UPDATE SUCH
   VIEWS. THESE VIEWS MAY NOT BE RELIED ON AS INVESTMENT ADVICE AND, BECAUSE
   INVESTMENT DECISIONS FOR AN EATON VANCE FUND ARE BASED ON MANY FACTORS, MAY
   NOT BE RELIED ON AS AN INDICATION OF TRADING INTENT ON BEHALF OF ANY EATON
   VANCE FUND.

   * It is not possible to invest directly in an Index.

*   Source: Thomson Financial. Investment operations commenced 3/2/01. Index
    information is available only at month-end; therefore, the line comparison
    begins at the next month-end following the commencement of the Fund's
    investment operations.

    The chart compares the Fund's total return with that of the S&P SmallCap 600
    Index, a broad-based, unmanaged market index of 600 small capitalization
    stocks. Returns are calculated by determining the percentage change in net
    asset value with all distributions reinvested. The lines on the chart
    represent the total returns of a $10,000 hypothetical investment in the Fund
    and in the S&P SmallCap 600 Index. The graph and performance table do not
    reflect the deduction of taxes that a shareholder would pay on Fund
    distributions or the redemption of Fund shares. The Index's total returns do
    not reflect any commissions or expenses that would have been incurred if an
    investor individually purchased or sold the securities represented in the
    Index. It is not possible to invest directly in the Index.

**  Returns are historical and are calculated by determining the percentage
    change in net asset value with all distributions reinvested. SEC returns for
    Class A shares reflect the maximum 5.75% sales charge. SEC returns for Class
    B shares reflect applicable CDSC based on the following schedule: 5% - 1st
    and 2nd years; 4% - 3rd year; 3% - 4th year; 2% - 5th year; 1% - 6th year.
    SEC 1-Year return for Class C shares reflects 1% CDSC.

    Past performance is no guarantee of future results. Investment return and
    principal value will fluctuate so that shares, when redeemed, may be worth
    more or less than their original cost.

AFTER-TAX PERFORMANCE
AS OF OCTOBER 31, 2003

 The tables below set forth the pre-tax and after-tax performance for the Fund.
 After-tax performance reflects the impact of federal income taxes on Fund
 distributions of dividends and capital gains, as well as capital gains taxes on
 the sale of Fund shares, while pre-tax performance does not. Because the
 objective of the Fund is to provide long-term, after-tax returns to
 shareholders, it is important for investors to know the effect of taxes on the
 Fund's return.

Class A, Class B, and Class C shares commenced operations on 3/2/01. Returns at
Public Offering Price (POP) reflect the deduction of the maximum sales charge,
while Returns at Net Asset Value (NAV) do not.

After-tax returns are calculated using the highest historical individual federal
income tax rate and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on a shareholder's tax situation and may differ from
those shown. After-tax returns are not relevant for shareholders who hold shares
in tax-deferred accounts or to shares held by non-taxable entities. Return After
Taxes on Distributions for a period may be the same as Return Before Taxes for
that period because no distributions were paid during that period or because the
taxable portion of distributions made during the period was insignificant. Also,
Return After Distributions and Sale of Fund Shares for a period may be greater
than Return After Taxes on Distributions for the same period because of realized
losses on the sale of Fund shares.

Past performance (both before and after taxes) is no guarantee of future
results. Investment return and principal value will fluctuate so that shares,
when redeemed, may be worth more or less than their original cost. Performance
is for the stated time period only; due to market volatility, the Fund's current
performance may be different.

EATON VANCE TAX-MANAGED SMALL-CAP GROWTH FUND 1.2 AS OF OCTOBER 31, 2003
NOTES TO FINANCIAL STATEMENTS

1  SIGNIFICANT ACCOUNTING POLICIES

   Eaton Vance Tax-Managed Small-Cap Growth Fund 1.2 (the Fund) is a diversified
   series of Eaton Vance Mutual Funds Trust (the Trust). The Trust is an entity
   of the type commonly known as a Massachusetts business trust and is
   registered under the Investment Company Act of 1940, as amended, as an
   open-end management investment company. The Fund currently offers three
   classes of shares. Class A shares are generally sold subject to a sales
   charge imposed at time of purchase. Class B and Class C shares are sold at
   net asset value and are subject to a contingent deferred sales charge (see
   Note 6). Class B shares held for eight years will automatically convert to
   Class A shares. The Fund previously offered Class D and Class I shares. Such
   offerings were discontinued during the year ended October 31, 2003. Each
   class represents a pro-rata interest in the Fund, but votes separately on
   class-specific matters and (as noted below) is subject to different expenses.
   Realized and unrealized gains and losses and net investment income and
   losses, other than class-specific expenses, are allocated daily to each class
   of shares based on the relative net assets of each class to the total net
   assets of the Fund. Each class of shares differs in its distribution plan and
   certain other class-specific expenses. The Fund invests all of its investable
   assets in interests of the Tax-Managed Small-Cap Growth Portfolio (the
   Portfolio), a New York Trust, having the same investment objective as the
   Fund. The value of the Fund's investment in the Portfolio reflects the Fund's
   proportionate interest in the net assets of the Portfolio (18.8% at October
   31, 2003). The performance of the Fund is directly affected by the
   performance of the Portfolio. The financial statements of the Portfolio,
   including the Portfolio of Investments, are included elsewhere in this report
   and should be read in conjunction with the Fund's financial statements.

   The following is a summary of significant accounting policies consistently
   followed by the Fund in the preparation of its financial statements. The
   policies are in conformity with accounting principles generally accepted in
   the United States of America.

   A INVESTMENT VALUATION -- Valuation of securities by the Portfolio is
   discussed in Note 1 A of the Portfolio's Notes to Financial Statements which
   are included elsewhere in this report.

   B INCOME -- The Fund's net investment income or loss consists of the Fund's
   pro-rata share of the net investment income or loss of the Portfolio, less
   all actual and accrued expenses of the Fund determined in accordance with
   accounting principles generally accepted in the United States of America.

   C EXPENSES -- The majority of expenses of the Trust are directly identifiable
   to an individual fund. Expenses which are not readily identifiable to a
   specific fund are allocated taking into consideration, among other things,
   the nature and type of expense and the relative size of the funds.

   D FEDERAL TAXES -- The Fund's policy is to comply with the provisions of the
   Internal Revenue Code applicable to regulated investment companies and to
   distribute to shareholders each year all of its taxable income, including any
   net realized gain on investments. Accordingly, no provision for federal
   income or excise tax is necessary. At October 31, 2003, the Fund, for federal
   income tax purposes, had a capital loss carryover of $11,876,431 which will
   reduce the taxable income arising from future net realized gain on
   investments, if any, to the extent permitted by the Internal Revenue Code and
   thus will reduce the amount of distributions to shareholders which would
   otherwise be necessary to relieve the Fund of any liability for federal
   income or excise tax. Such capital loss carryover will expire on October 31,
   2010.

   E OTHER -- Investment transactions are accounted for on a trade-date basis.
   Dividends to shareholders are recorded on the ex-dividend date.

   F USE OF ESTIMATES -- The preparation of the financial statements in
   conformity with accounting principles generally accepted in the United States
   of America requires management to make estimates and assumptions that affect
   the reported amounts of assets and liabilities at the date of the financial
   statements and the reported amounts of income and expense during the
   reporting period. Actual results could differ from those estimates.

2  DISTRIBUTIONS TO SHAREHOLDERS

   It is the present policy of the Fund to make at least one distribution
   annually (normally in December) of all or substantially all of its net
   investment income, if any, and at least one distribution annually of all or
   substantially all of its net realized capital gains (reduced by available
   capital loss carryforwards from prior years, if any.) Distributions are paid
   in the form of additional shares of the Fund, or at the election of the
   shareholder, in cash. Shareholders may reinvest all distributions in
   additional shares of the Fund at the net asset value as of the close of
   business on the ex-dividend date. The Fund distinguishes between
   distributions on a tax basis and a financial reporting basis.

                                       12
<Page>

   Accounting principles generally accepted in the United States of America
   require that only distributions in excess of tax basis earnings and profits
   be reported in the financial statements as a return of capital. Permanent
   differences between book and tax accounting relating to distributions are
   reclassified to paid-in capital.

3  SHARES OF BENEFICIAL INTEREST

   The Fund's Declaration of Trust permits the Trustees to issue an unlimited
   number of full and fractional shares of beneficial interest (without par
   value). Transactions in Fund shares were as follows:

4  TRANSACTIONS WITH AFFILIATES

   The administration fee is earned by Eaton Vance Management (EVM) as
   compensation for managing and administering the business affairs of the Fund.
   Under the administration agreement, EVM earns a fee in the amount of 0.15%
   per annum of average daily net assets of the Fund. For the year ended October
   31, 2003, the administration fee amounted to $55,178. To reduce the net
   investment loss of the Fund, EVM was allocated $15,005 of the Fund's
   operating expenses for the year ended October 31, 2003. The Portfolio has
   engaged Boston Management and Research (BMR), a subsidiary of EVM, to render
   investment advisory services. See Note 2 of the Portfolio's Notes to
   Financial Statements which are included elsewhere in this report. EVM serves
   as the sub-transfer agent of the Fund and receives from the transfer agent an
   aggregate fee based upon the actual expenses incurred by EVM in the
   performance of those services. For the year ended October 31, 2003, EVM
   earned $8,394 in sub-transfer agent fees.

   Except for Trustees of the Fund and the Portfolio who are not members of
   EVM's or BMR's organization, officers and Trustees receive remuneration for
   their services to the Fund out of the investment adviser fee earned by BMR.
   Trustees of the Fund that are not affiliated with EVM or BMR may elect to
   defer receipt of all or a percentage of their annual fees in accordance with
   the terms of the Trustees Deferred Compensation Plan. For the year ended
   October 31, 2003, no significant amounts have been deferred.

   Eaton Vance Distributors, Inc. (EVD), a subsidiary of EVM and the Fund's
   principal underwriter, received $7,069 as its portion of the sales charge on
   sales of Class A shares for the year ended October 31, 2003.

   Certain officers and Trustees of the Fund and Portfolio are officers of the
   above organizations.

5  DISTRIBUTION AND SERVICE PLANS

   The Fund has in effect distribution plans for Class B shares (Class B Plan),
   Class C shares (Class C Plan) and Class D shares (Class D Plan) pursuant to
   Rule 12b-1 under the Investment Company Act of 1940 and a service plan for
   Class A shares (Class A Plan) (collectively, the Plans). The Class B, Class C
   and Class D Plans require the Fund to pay EVD amounts equal to 1/365 of 0.75%
   of the Fund's average daily net assets attributable to Class B, Class C and
   Class D shares for providing ongoing distribution services and facilities to
   the Fund. The Fund will automatically discontinue payments to EVD during any
   period in which there are no

                                       13
<Page>

   outstanding Uncovered Distribution Charges, which are equivalent to the sum
   of (i) 6.25% of the aggregate amount received by the Fund for the Class B,
   Class C and Class D shares sold, plus (ii) interest calculated by applying
   the rate of 1% over the prevailing prime rate to the outstanding balance of
   Uncovered Distribution Charges of EVD of each respective class, reduced by
   the aggregate amount of contingent deferred sales charges (see Note 6) and
   daily amounts theretofore paid to EVD by each respective class. The Fund paid
   or accrued $77,699, $91,427, and $2,757 for Class B, Class C, and Class D
   shares, respectively, to or payable to EVD for the year ended October 31,
   2003, representing 0.75% of the average daily net assets for Class B, Class
   C, and Class D shares, respectively. At October 31, 2003, the amount of
   Uncovered Distribution Charges of EVD calculated under the Plans was
   approximately $738,000 and $1,188,000 for Class B and Class C shares,
   respectively.

   The Plans authorize the Fund to make payments of service fees to EVD,
   investment dealers and other persons in the amount of 0.25% of the Fund's
   average daily net assets attributable to Class A, Class B, Class C and Class
   D shares for each fiscal year. Service fee payments will be made for personal
   services and/or the maintenance of shareholder accounts. Service fees are
   separate and distinct from the sales commissions and distribution fees
   payable by the Fund to EVD and, as such, are not subject to automatic
   discontinuance when there are no outstanding Uncovered Distribution Charges
   of EVD. Service fee payments for the year ended October 31, 2003 amounted to
   $34,648, $25,900, $30,476, and $919 for Class A, Class B, Class C, and Class
   D shares, respectively.

6  CONTINGENT DEFERRED SALES CHARGE

   A contingent deferred sales charge (CDSC) generally is imposed on redemptions
   of Class B and Class D shares made within six years of purchase and on
   redemptions of Class C shares made within one year of purchase. Generally,
   the CDSC is based upon the lower of the net asset value at date of redemption
   or date of purchase. No charge is levied on shares acquired by reinvestment
   of dividends or capital gain distributions. Class A shares may be subject to
   a 1% CDSC if redeemed within one year of purchase (depending upon the
   circumstances of the purchase). The Class B and Class D CDSC is imposed at
   declining rates that begin at 5% in the case of redemptions in the first and
   second year after purchase, declining one percentage point in each subsequent
   year. Class C shares will be subject to a 1% CDSC if redeemed within one year
   of purchase.

   No CDSC is levied on shares which have been sold to EVM, its affiliates, or
   to their respective employees or clients and may be waived under certain
   other limited conditions. CDSC charges received on Class B and Class C
   redemptions are paid to EVD to reduce the amount of Uncovered Distribution
   Charges calculated under the Class B, Class C and Class D Plans, respectively
   (see Note 5). CDSC assessed on Class B, Class C and Class D shares when no
   Uncovered Distribution Charges exist for the respective class will be
   credited to the Fund. EVD received approximately $14, $51,000, $4,000, and
   $3,500 of CDSC paid by shareholders for Class A shares, Class B shares, Class
   C shares, and Class D shares, respectively, for the year ended October 31,
   2003.

7  INVESTMENT TRANSACTIONS

   Increases and decreases in the Fund's investment in the Portfolio for the
   year ended October 31, 2003, aggregated $11,053,174 and $13,679,441,
   respectively.

EATON VANCE TAX-MANAGED SMALL-CAP GROWTH FUND 1.2 AS OF OCTOBER 31, 2003
INDEPENDENT AUDITORS' REPORT

TO THE TRUSTEES OF EATON VANCE MUTUAL FUNDS TRUST AND SHAREHOLDERS OF EATON
VANCE TAX-MANAGED SMALL-CAP GROWTH FUND 1.2:

We have audited the accompanying statement of assets and liabilities of Eaton
Vance Tax-Managed Small-Cap Growth Fund 1.2 (formally Eaton Vance Tax-Managed
Emerging Growth Fund 1.2) (the Fund) ( one of the series of Eaton Vance Mutual
Funds Trust) as of October 31, 2003, and the related statement of operations for
the year then ended, the statements of changes in net assets for the years ended
October 31, 2003 and 2002 and the financial highlights for the years ended
October 31, 2003 and 2002, and the period from the start of business, March 2,
2001, to October 31, 2001. 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 audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. 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. 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
audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Eaton Vance
Tax-Managed Small-Cap Growth Fund 1.2 at October 31, 2003, and the results of
its operations, the change in its net assets and its financial highlights for
the respective stated periods in conformity with accounting principles generally
accepted in the United States of America.

TAX-MANAGED SMALL-CAP GROWTH PORTFOLIO AS OF OCTOBER 31, 2003

NOTES TO FINANCIAL STATEMENTS

1  SIGNIFICANT ACCOUNTING POLICIES

   Tax-Managed Small-Cap Growth Portfolio (the Portfolio) is registered under
   the Investment Company Act of 1940, as amended, as a diversified open-end
   management investment company. The Portfolio, which was organized as a trust
   under the laws of the State of New York on June 22, 1998, seeks to achieve
   long-term after-tax returns by investing in a diversified portfolio of equity
   securities of emerging growth companies. The Declaration of Trust permits the
   Trustees to issue interests in the Portfolio. At October 31, 2003, the Eaton
   Vance Tax-Managed Small-Cap Growth Fund 1.2 held an approximate 18.8%
   interest in the Portfolio and two other investors owned an interest greater
   than 10% that aggregated 81.2%. The following is a summary of significant
   accounting policies consistently followed by the Portfolio in the preparation
   of its financial statements. The policies are in conformity with accounting
   principles generally accepted in the United States of America.

   A INVESTMENT VALUATION -- Marketable securities, including options, that are
   listed on foreign or U.S. securities exchanges are valued at closing sale
   prices on the exchange where such securities are principally traded.
   Marketable securities listed in the NASDAQ National Market System are valued
   at the NASDAQ official closing price. Unlisted or listed securities for which
   closing sale prices are not available are generally valued at the mean
   between the latest bid and asked prices. Futures positions on securities or
   currencies are generally valued at closing settlement prices. Short-term debt
   securities with a remaining maturity of 60 days or less are valued at
   amortized cost, which approximates fair value. Other fixed income and debt
   securities, including listed securities and securities for which price
   quotations are available, will normally be valued on the basis of valuations
   furnished by a pricing service. Investments for which valuations or market
   quotations are unavailable are valued at fair value using methods determined
   in good faith by or at the direction of the Trustees.

   B INCOME -- Dividend income is recorded on the ex-dividend date for dividends
   received in cash and/or securities. However, if the ex-dividend date has
   passed, certain dividends from foreign securities are recorded as the
   Portfolio is informed of the ex-dividend date. Interest income is recorded on
   the accrual basis.

   C INCOME TAXES -- The Portfolio is treated as a partnership for federal tax
   purposes. No provision is made by the Portfolio for federal or state taxes on
   any taxable income of the Portfolio because each investor in the Portfolio is
   ultimately responsible for the payment of any taxes on its share of taxable
   income. Since the Portfolio's investors include regulated investment
   companies that invest all or substantially all of their assets in the
   Portfolio, the Portfolio normally must satisfy the applicable source of
   income and diversification requirements (under the Internal Revenue Code) in
   order for its investors to satisfy them. The Portfolio will allocate at least
   annually among its investors, each investor's distributive share of the
   Portfolio's net investment income, net realized capital gains, and any other
   items of income, gain, loss, deduction or credit.

   D FINANCIAL FUTURES CONTRACTS -- Upon entering a financial futures contract,
   the Portfolio is required to deposit either in cash or securities an amount
   (initial margin) equal to a certain percentage of the purchase price
   indicated in the financial futures contract. Subsequent payments are made or
   received by the Portfolio (variation margin) each day, dependent on daily
   fluctuations in the value of the underlying security, and are recorded for
   book purposes as unrealized gains or losses by the Portfolio. The Portfolio's
   investment in financial futures contracts is designed to hedge against
   anticipated future changes in price of current or anticipated Portfolio
   positions. Should prices move unexpectedly, the Portfolio may not achieve the
   anticipated benefits of the financial futures contracts and may realize a
   loss.

   E FOREIGN CURRENCY TRANSLATION -- Investment valuations, other assets and
   liabilities initially expressed in foreign currencies are converted each
   business day into U.S. dollars based upon current exchange rates. Purchases
   and sales of foreign investment securities and income and expenses are
   converted into U.S. dollars based upon currency exchange rates prevailing on
   the respective dates of such transactions. Recognized gains or losses on
   investment transactions attributable to foreign currency exchange rates are
   recorded for financial statement purposes as net realized gains and losses on
   investments. That portion of unrealized gains and losses on investments that
   results from fluctuations in foreign currency exchange rates is not
   separately disclosed.

                                       25
<Page>

   F EXPENSE REDUCTION -- Investors Bank & Trust Company (IBT) serves as
   custodian of the Portfolio. Pursuant to the custodian agreement, IBT receives
   a fee reduced by credits which are determined based on the average daily cash
   balances the Portfolio maintains with IBT. All significant credit balances
   used to reduce the Portfolio's custodian fees are reported as a reduction of
   expenses on the Statement of Operations.

   G SECURITIES SOLD SHORT -- The Portfolio may sell a security short if it owns
   at least an equal amount of the security sold short or another security
   exchangeable for an equal amount of the security sold short in anticipation
   of a decline in the market price of the securities or in order to hedge
   portfolio positions. The Portfolio will generally borrow the security sold in
   order to make delivery to the buyer. Upon executing the transaction, the
   Portfolio records the proceeds as deposits with brokers on the Statement of
   Assets and Liabilities and establishes an offsetting payable for securities
   sold short for the securities due on settlement. The proceeds are retained by
   the broker as collateral for the short position. The liability is
   marked-to-market on a daily basis and the Portfolio is required to pay the
   lending broker any dividend or interest income earned while the short
   position is open. A gain or loss is recorded when the security is delivered
   to the broker. The Portfolio may recognize a loss on the transaction if the
   market value of the securities sold increases before the securities are
   delivered.

   H USE OF ESTIMATES -- The preparation of the financial statements in
   conformity with accounting principles generally accepted in the United States
   of America requires management to make estimates and assumptions that affect
   the reported amounts of assets and liabilities at the date of the financial
   statements and the reported amounts of income and expense during the
   reporting period. Actual results could differ from those estimates.

   I OTHER -- Investment transactions are accounted for on a trade-date basis.

2  INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

   The investment adviser fee is earned by Boston Management and Research (BMR),
   a wholly-owned subsidiary of Eaton Vance Management (EVM), as compensation
   for management and investment advisory services rendered to the Portfolio.
   BMR receives a monthly advisory fee in the amount of 5/96th of 1% (equal to
   0.625% annually) of average daily net assets of the Portfolio up to $500
   million, and at reduced rates as daily net assets exceed that level. For the
   year ended October 31, 2003, the advisory fee amounted to $1,279,944. Except
   for Trustees of the Portfolio who are not members of EVM's or BMR's
   organization, officers and Trustees receive remuneration for their services
   to the Portfolio out of the investment adviser fee. Trustees of the Portfolio
   that are not affiliated with BMR may elect to defer receipt of all or a
   percentage of their annual fees in accordance with the terms of the Trustees
   Deferred Compensation Plan. For the year ended October 31, 2003, no
   significant amounts have been deferred.

   Certain officers and Trustees of the Portfolio are officers of the above
   organizations.

3  INVESTMENT TRANSACTIONS

   Purchases and sales of investments, other than short-term obligations,
   aggregated $481,564,189 and $517,660,598, respectively, for the year ended
   October 31, 2003.

4  FEDERAL INCOME TAX BASIS OF UNREALIZED APPRECIATION (DEPRECIATION)

   The cost and unrealized appreciation (depreciation) in value of the
   investments owned at October 31, 2003, as computed on a federal income tax
   basis, were as follows:

   --------------------------------------------------------------------------
   Gross unrealized appreciation                            $      40,851,621
   Gross unrealized depreciation                                   (1,690,337)
   --------------------------------------------------------------------------

   NET UNREALIZED APPRECIATION                              $      39,161,284
   --------------------------------------------------------------------------
</Table>

5  FINANCIAL INSTRUMENTS

   The Portfolio may trade in financial instruments with off-balance sheet risk
   in the normal course of its investing activities to assist in managing
   exposure to various market risks. These financial instruments include forward
   foreign currency contracts and financial futures contracts and may involve,
   to a varying degree, elements of risk in excess of the amounts recognized for
   financial statement purposes.

   The notional or contractual amounts of these instruments represent the
   investment the Portfolio has in particular classes of financial instruments
   and does not necessarily represent the amounts potentially subject to risk.
   The measurement of the risks associated with these instruments is meaningful
   only when all related and offsetting transactions are considered. The
   Portfolio did not have any open obligations under these financial instruments
   at October 31, 2003.

                                       26

6  LINE OF CREDIT

   The Portfolio participates with other portfolios and funds managed by BMR and
   EVM and its affiliates in a $150 million unsecured line of credit agreement
   with a group of banks. Borrowings will be made by the Portfolio solely to
   facilitate the handling of unusual and/or unanticipated short-term cash
   requirements. Interest is charged to each participating portfolio or fund
   based on its borrowings at an amount above either the Eurodollar rate or
   Federal Funds rate. In addition, a fee computed at an annual rate of 0.10% on
   the daily unused portion of the line of credit is allocated among the
   participating portfolios and funds at the end of each quarter. The Portfolio
   did not have any significant borrowings or allocated fees during the year
   ended October 31, 2003.

7  RESTRICTED SECURITIES

   At October 31, 2003, the Portfolio owned the following securities
   (representing 0.15% of net assets) which were restricted as to public resale
   and not registered under the Securities Act of 1933. The fair value is
   determined using methods determined in good faith by or at the direction of
   the Trustees.

TAX-MANAGED SMALL-CAP GROWTH PORTFOLIO AS OF OCTOBER 31, 2003
INDEPENDENT AUDITORS' REPORT

TO THE TRUSTEES AND INVESTORS OF TAX-MANAGED SMALL-CAP GROWTH PORTFOLIO:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Tax-Managed Small-Cap Growth Portfolio (the
Portfolio) (formerly Tax-Managed Emerging Growth Portfolio) as of October 31,
2003, and the related statement of operations for the year then ended, the
statements of changes in net assets for the years ended October 31, 2003 and
2002 and the supplementary data for the years ended October 31, 2003 and 2002
and the period from the start of business, March 1, 2001 to October 31, 2001.
These financial statements and supplementary data are the responsibility of the
Portfolio's management. Our responsibility is to express an opinion on these
financial statements and supplementary data based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and supplementary data 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 held as of October 31, 2003 by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
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 audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements and supplementary data present fairly,
in all material respects, the financial position of the Tax-Managed Small-Cap
Growth Portfolio at October 31, 2003, the results of its operations, the changes
in its net assets and the supplementary data for the respective stated periods
in conformity with accounting principles generally accepted in the United States
of America.
