no guarantee of future results. Current performance may be lower or higher than
the performance data quoted herein. For the most recent month-end performance
results, visit our website at www.ssrfunds.com. The fund's share price, yield
and return will fluctuate, and you may have a gain or loss when you sell your
shares. All returns assume reinvestment of capital gains distributions and
income dividends at net asset value. The returns shown do not reflect the
deduction of taxes that a shareholder would pay on fund distributions or the
redemption of fund shares.

Average annual total return represents the rate one would have to earn each year
of a given time period in order to end up with the fund's actual cumulative
return for those years. The chart labeled $10,000 Over 10 Years measures the
growth of a lump sum invested (less applicable maximum sales charge, if any)
over a ten-year period, and compares the performance to an index.

The S&P 500 Index (officially the "Standard & Poor's 500 Composite Stock Price
Index") is an unmanaged index of 500 U.S. stocks. The index does not take
transaction charges into consideration. It is not possible to invest directly in
an index.

The Exchange Fund Average is an average created by State Street Research using
data provided by Lipper, Inc. The average consists of funds with similar goals
and shows you how well the fund has done compared to competing funds.
- --------------------------------------------------------------------------------

Reasons for the Fund's Performance
In the early part of 2004, the equity markets essentially moved sideways in
light trading as concerns about the election, spiking oil prices and interest
rate increases kept investors on the sidelines. But a decisive presidential
victory for George W. Bush proved to be a springboard for investors. The equity
markets took off in the fourth quarter of 2004 and focused on strong corporate
profits and company fundamentals. In this environment, strong stock selection
in the financial services, consumer discretionary and producer durables sectors
aided performance. In addition, overweight positions in energy and integrated
oils benefited the fund. Energy stocks capitalized on elevated commodity prices
during the year. SLM, Target and ExxonMobil were especially strong contributors
to returns.

In contrast, the portfolio's exposure to autos & transportation, consumer
staples and health care was detrimental to returns. Coca-Cola, Altria and Wyeth
were notable detractors from performance.

A Word about Risk
The major risks of stock investing include sudden and unpredictable drops in
value and periods of lackluster performance. The fund may invest in companies
with some international business, and also may invest in foreign companies;
therefore, the fund is subject to the risks associated with international
investing, such as changes in exchange rates, and different government
regulations, economic conditions and accounting standards.

About Your Fund Expenses
As a fund shareholder, you incur ongoing expenses, which include management fees
and "other" expenses. The examples below illustrate the ongoing cost in dollars
of investing in the fund and allow you to compare these costs with the expenses
of other funds. The examples are based on a $1,000 investment at the beginning
of the period and held for the entire period from June 30, 2004, to December 31,
2004.

Actual Fund Return is based on the fund's actual return and expenses. To
estimate the ongoing expenses you paid during the entire period shown, 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 shown for your
fund under the column "Expenses Paid during the Period."

Hypothetical 5% Return is based on the fund's actual expense ratio and an
assumed rate of 5% per year before expenses. Please note that the return used is
not the fund's actual return; therefore, this information may not be used to
estimate your actual ending balance and expenses paid during the period. To
compare your fund's ongoing expenses with those of other funds, simply compare
this 5% hypothetical example with the 5% hypothetical examples shown in the
share holder reports of other funds.

                                             State Street Research Exchange Fund


Notes to Financial Statements
- --------------------------------------------------------------------------------
December 31, 2004

Note 1
State Street Research Exchange Fund is a series of State Street Research
Exchange Trust (the "Trust"), which is organized 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 is presently the only
series of the Trust.

The investment objective of the fund is to provide long-term growth of capital
and consequent long-term growth of income. In seeking to achieve its investment
objective, the fund invests primarily in common stocks, or securities
convertible into common stocks, that have long-term growth potential.

The following significant accounting policies are consistently followed by the
fund in preparing its financial statements, and such policies are in conformity
with accounting principles generally accepted in the United States of America.

A. Investment Valuation
Values for listed equity securities reflect final sales on national securities
exchanges quoted prior to the close of the New York Stock Exchange.
Over-the-counter securities quoted on the National Association of Securities
Dealers Automated Quotation ("Nasdaq") system are valued at closing prices
supplied through such system. If not quoted on the Nasdaq system, such
securities are valued at prices obtained from independent brokers. In the
absence of recorded sales, valuations are at the mean of the closing bid and
asked quotations. Short-term securities maturing within sixty days are valued
at amortized cost. Other securities, if any, are valued at their fair value as
determined in good faith under consistently applied procedures established by
and under the supervision of the Trustees. In the event that the market
quotations for a portfolio instrument are not deemed to be readily available,
the Adviser's Valuation Committee determines the fair value for such portfolio
instrument. The fair value of any such portfolio instruments are determined
based upon a consideration of all available facts and information. The fair
valuation of a restricted portfolio instrument reflects the inherent worth of
the portfolio instrument, without regard to the restrictive feature, adjusted
for any diminution in value resulting from the restrictive feature. The Adviser
and the custodian also monitor domestic and foreign markets and news
information for any developing events that may have an impact on the valuation
of portfolio instruments. Such monitoring includes general market news and
financial market information sources currently utilized in making investment
decisions, trading and investment personnel located abroad, foreign regional
brokers, and/or foreign custodians. The value assigned to these securities is
based upon available information at the time, and does not necessarily
represent the amount which might ultimately be realized upon sale.

B. Security Transactions
Security transactions are accounted for on the trade date (date the order to
buy or sell is executed). Realized gains or losses are reported on the basis of
identified cost of securities delivered. As part of the custodian contract
between the custodian bank and the fund, the custodian bank has a lien on the
securities of the fund to the extent permitted by the fund's investment
restriction to cover any advances made by the custodian bank for the settlement
of securities purchased by the fund. At December 31, 2004, the payable to the
custodian bank of $3,406,638 represents the amount due for cash advance for the
settlement of securities purchased.

C. Net Investment Income
Net investment income is determined daily and consists of interest and
dividends accrued and discount earned, less the estimated daily expenses of the
fund. Interest income is accrued daily as earned. Dividend income is accrued on
the ex-dividend date.

D. Dividends
Dividends from net investment income are declared and paid or reinvested
quarterly. Net realized short-term capital gains, if any, are distributed
annually.

Income dividends and capital gains distributions are determined in accordance
with federal income tax regulations which may differ from accounting principles
generally accepted in the United States of America. The difference is primarily
due to differing treatments for non-taxable redemptions in kind and the
disposition of securities that have different bases for financial reporting and
tax purposes. The permanent book and tax basis difference relating to
shareholder distributions will result in reclassifications to paid-in-capital.
The fund has designated $4,387,534 as ordinary income dividends.

E. Federal Income Taxes
No provision for federal income taxes is necessary with respect to net
investment income because the fund has elected to qualify under Subchapter M of
the Internal Revenue Code and its policy is to distribute substantially all of
such income within the prescribed time periods. The fund retains and designates
as undistributed gains all of its taxable net long-term capital gains and pays
federal income taxes thereon on behalf of the shareholders.

At December 31, 2004, the fund had a capital loss carryforward of $7,883,083
available, to the extent provided in regulations, to offset future capital
gains, if any, of which $770,500 and $7,112,583 expire on December 31, 2009 and
2010, respectively.

To the extent book/tax differences are permanent in nature, such amounts are
reclassified within the capital accounts based on federal tax basis treatment.
The fund reclassified for book purposes amounts arising from permanent book/tax
differences primarily relating to differing treatments for non-taxable
redemptions in kind and the disposition of securities that have different bases
for financial reporting and tax purposes. At December 31, 2004, the components
of distributable earnings on a tax basis differ from the amounts reflected in
the Statement of Assets and Liabilities by temporary book/tax differences
largely arising from capital loss carryforwards. At December 31, 2004, the tax
basis distributable earnings were $61,022 in undistributed ordinary income, $0
in undistributed short-term capital gains and $0 in undistributed long-term
gains.

F. Estimates
The preparation of 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 and disclosure of contingent assets and liabilities
at the date of the financial statements and the reported amounts of income and
expenses during the reporting period. Actual results could differ from these
estimates.

G. Securities Lending
The fund may seek additional income by lending portfolio securities to
qualified institutions. The fund will receive cash or securities as collateral
in an amount equal to at least 100% of the current market value of any loaned
securities plus accrued interest. By reinvesting any cash collateral it
receives in these transactions, the fund could realize additional gains and
losses. If the borrower fails to return the securities and the value of the
collateral has declined during the term of the loan, the fund will bear the
loss. At December 31, 2004, there were no loaned securities. During the year
ended December 31, 2004, income from securities lending amounted to $2,665.

Note 2
The Trust and the Adviser have entered into an agreement under which the
Adviser earns monthly fees at an annual rate of 0.50% of the fund's average net
assets. In consideration of these fees, the Adviser furnishes the fund with
management, investment advisory, statistical and research facilities and
services. The Adviser also pays all salaries, rent and certain other expenses
of management. During the year ended December 31, 2004, the fees pursuant to
such agreement amounted to $1,515,452.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), provides certain shareholder services to the fund such as
responding to inquiries and instructions from investors with respect to
redemption of shares of the fund. Total shareholder service costs are allocated
to each fund in the same ratios as the transfer agent costs. During the year
ended December 31, 2004, the amount of such expenses allocated to the fund was
$3,897.


                                                                               7


The fees of the Trustees not currently affiliated with the Adviser amounted to
$25,445 during the year ended December 31, 2004.

The fund has agreed to pay the Adviser for certain administrative costs incurred
in providing other assistance and services to the fund. The fee was based on a
fixed amount that has been allocated equally among the State Street Research
funds. During the year ended December 31, 2004, the amount of such expenses was
$108,870.

During the year ended December 31, 2004, the Adviser conducted an internal
review regarding the use of fund brokerage commissions in consideration of the
distribution of shares. In connection with this review, the Adviser determined
to reimburse the fund the entire amount of any such identified brokerage
commissions, and reviewed this matter with the Board of Trustees of the fund.
This amount is shown in the total amount of $98,840 as "Net increase from
payment by affiliate" on the Statement of Operations.

Note 3
For the year ended December 31, 2004, exclusive of short-term investments and
U.S. government obligations, purchases and sales of securities, including
$26,348,500 representing redemptions in kinds, aggregated $11,928,358 and
$38,197,200, respectively.

Note 4
The Trustees have the authority to issue an unlimited number of shares of
beneficial interest at $0.001 par value per share. At December 31, 2004, the
Adviser held 13,766 shares of the fund.

Note 5
As of the close of business on January 28, 2005, BlackRock Exchange Portfolio
("the BlackRock Fund"), a newly created series of the BlackRock Funds, will
acquire all of the assets and assume all of the certain stated liabilities of
the fund.

REPORT OF

          Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders
of State Street Research Exchange Fund:

We have audited the accompanying statement of assets and liabilities, including
the portfolio holdings, of State Street Research Exchange Fund (the "Fund"), a
series of State Street Research Exchange Trust, as of December 31, 2004, and
the related statement of operations for the year then ended, and the statement
of changes in net assets, and the financial highlights for each of the two
years in the period 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 audits. The financial highlights for each of the years in the
three-year period ended December 31, 2002, were audited by other auditors whose
report dated February 12, 2003, expressed an unqualified opinion on such
financial highlights.

We conducted our audits in accordance with 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 consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of December 31, 2004, by correspondence with the custodian.
We believe that our audits provide 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 the
Fund as of December 31, 2004, the results of its operations for the year then
ended, and the changes in its net assets and the financial highlights for each
of the two years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

pre-approval by the Audit Committee pursuant to paragraph (c)(7)(ii) of Rule
2-01 of Regulation S-X during the Registrant's last two fiscal years.

(e)(1) The Audit Committee has determined that all work performed for the
Registrant by Deloitte & Touche LLP will be pre-approved by the full Audit
Committee and, therefore, has not adopted pre-approval procedures.

    (2) None.

(f) Not applicable.

(g) Non-Audit Fees - Represents fees for audit-related, tax and other
non-audit services rendered by the principal accountant to the Registrant,

    Fiscal Year Ended October 31, 2003  $ 2,600
    Fiscal Year Ended October 31, 2004  $63,000

    accountant to the Registrant's investment adviser (not including any
    subadviser whose role is primarily portfolio management and is
    subcontracted with or overseen by another investment adviser) and any
    entity controlling, controlled by, or under common control with the
    investment adviser that provides ongoing services to the Registrant and
    that were not pre-approved by the Audit Committee are compatible with
    maintaining the principal accountant's independence.
