TAX-MANAGED SMALL-CAP VALUE PORTFOLIO AS OF OCTOBER 31, 2003
NOTES TO FINANCIAL STATEMENTS

1  SIGNIFICANT ACCOUNTING POLICIES

   Tax-Managed Small-Cap Value 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 December 10, 2001, seeks to
   achieve long-term after-tax returns by investing in a diversified portfolio
   of value stocks of small-cap 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 Value Fund held an approximate 41.2% interest in
   the Portfolio and one other investor owned an interest greater than 10% that
   equaled 58.5%. 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 CONTRACT -- 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 (margin maintenance) 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 PUT OPTIONS -- Upon the purchase of a put option by the Portfolio, the
   premium paid is recorded as an investment, the value of which is
   marked-to-market daily. When a purchased option expires, the Portfolio will
   realize a loss in the amount of the cost of the option. When the Portfolio
   enters into a closing sale transaction, the Portfolio will realize a gain or
   loss depending on whether the sales proceeds from the closing sale
   transaction are greater or less than the cost of the option. When the
   Portfolio exercises a put option, settlement is made in cash. The risk
   associated with purchasing options is limited to the premium originally paid.

   F 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
   convertible or exchangeable for an equal amount of the security sold short.
   Such transactions are done 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 in the Statement of Assets and Liabilities and
   establishes an offsetting payable

                                       22
<Page>

   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 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.

   G 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.

   H 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.

   I 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.

   J 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.
   Under the advisory agreement, BMR receives a monthly advisory fee in the
   amount of 1.00% 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 $282,718.
   Pursuant to a sub-advisory agreement, BMR has delegated the investment
   management of the Portfolio to Fox Asset Management LLC (Fox), a
   majority-owned subsidiary of EVM. BMR pays Fox a monthly fee for sub-advisory
   services provided to the Portfolio in the amount of 0.75% annually of average
   daily net assets up to $500 million, and at reduced rates as daily net assets
   exceed that level. 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 $17,307,757 and $5,277,509, 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:

<Table>
                                       
   AGGREGATE COST                         $  30,760,114
   ----------------------------------------------------
   Gross unrealized appreciation          $   6,356,187
   Gross unrealized depreciation               (845,674)
   ----------------------------------------------------
   NET UNREALIZED APPRECIATION            $   5,510,513
   ----------------------------------------------------
</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 written
   options,

                                       23
<Page>

   forward foreign currency exchange 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.

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 for the
   year ended October 31, 2003.

7  INTERESTHOLDER MEETING

   The Portfolio held a Special Meeting of Interestholders on June 6, 2003 to
   elect Trustees. The results of the vote were as follows:

   a Trustee effective July 1, 2003 pursuant to the mandatory retirement policy
   of the Portfolio.
