FROM THE CHAIRMAN

[Photo of Ralph F. Verni]

DEAR SHAREHOLDER:

Another good year for the U.S. economy has extended America's cycle of
prosperity to nine consecutive years. Gross domestic product, a measure of goods
and services produced in the U.S., rose at an estimated annual rate of 4.0%.
Personal income has risen and consumer spending has been strong. Inflation
remained relatively low as productivity gains offset wage gains. However, the
Consumer Price Index moved up one full percentage point from 1.6% to 2.6%. The
Federal Reserve Board responded to these indicators of strength by raising
short-term interest rates by 3/4% in three 1/4% steps in the second half of the
year.

STOCKS
The U.S. stock market delivered another year of double-digit gains. The S&P
500(1) rose 21.0% during the 12-month period ended December 31, 1999. However,
S&P 500 technology stocks accounted for a disproportionate share of those gains.
Technology stocks in the S&P 500 gained 74.6%. Non- technology S&P 500 stocks
gained only 4.5%. The technology-heavy Nasdaq gained 85.6% for the year.

BONDS
The bond market was hurt by the Federal Reserve Board's interest-rate hikes and
by factors associated with Y2K. Fears that issuers would go to the market with
their debt issues early in the year drove yields up and bond prices down.
However, those fears were not realized, and the market began to close the yield
gap in the second half of the year. In this environment, mortgage bonds held up
better than government and corporate bonds. High yield bonds finished the year
ahead of other bond sectors, but with modest single-digit results.

INTERNATIONAL
Economic growth around the globe was better than expected. In Asia and certain
emerging markets, economies rebounded from last year's currency woes faster than
anticipated. Japan has shown the first signs of real progress in revitalizing
its economy in nearly a decade. That was reflected in strong stock market
performance for the year, especially among small Japanese companies. Europe
delivered generally favorable results as did the emerging markets of Latin
America.

OUTLOOK AND OPPORTUNITIES
As we enter the year 2000, many markets are poised for growth. However, there
are also areas, such as the technology sector in the U.S., where extraordinarily
high valuations suggest caution in the months ahead. Now is a good time to
consult your financial professional about the strategies that make sense for
your personal portfolio.

And, as always, we thank you for investing in State Street Research.

    Sincerely,

/s/ Ralph F. Verni

    Chairman

PORTFOLIO MANAGER'S REVIEW

Tax-Exempt Fund: A challenging environment for municipal bonds

[Photo of Paul Clifford]
   Paul Clifford
 Portfolio Manager

We spoke with Paul Clifford, portfolio manager of State Street Research
Tax-Exempt Fund, about the Fund's performance for the year ended December 31,
1999 and his views on the period ahead.

Q: HOW DID THE FUND PERFORM LAST YEAR?

A: It was a disappointing year for the municipal bond market and also for the
Fund. Class A shares returned -4.34% for the 12 months ended December 31, 1999
[does not reflect sales charge](2). That was better than the Lipper General
Municipal Debt Fund Average, which returned -4.63%. However, the Fund
underperformed the Lehman Brothers Municipal Bond Index(1), which returned
- -2.06% for the same period.

Q: WHAT FACTORS HURT PERFORMANCE IN 1999?

A: During the first five months of the year we lengthened the Fund's duration.
(Duration is a measure of a fund's sensitivity to changing interest rates.) When
interest rates decline, longer duration can help return. However, when interest
rates rise -- as they did in 1999 -- it hurts all bond funds, but particularly a
fund with longer duration.

Q: WHY DID YOU LENGTHEN DURATION?

A: At the beginning of 1999, our view was that interest rates were positioned to
decline. However, higher-than- expected economic growth put the Federal Reserve
Board on guard about inflation, and interest rates moved up, not down.

Q: BESIDES INTEREST RATES, WHAT OTHER FACTORS AFFECTED THE MUNICIPAL BOND
   MARKET?

A: In general, municipal bond funds were hurt by a poor technical environment.
In other words, there were too many sellers and too few buyers during most of
the year. Liquidity in the market was poor overall as cash flowed out of many
municipal bond funds and into other areas of the market where investors were
attracted to higher returns.

Q: DID YOU SHIFT YOUR STRATEGY AS THE ENVIRONMENT CHANGED?

A: Yes. As it became apparent that the economy was getting stronger, not weaker,
we shortened the Fund's duration. We also improved the portfolio's liquidity --
we sold some of the Fund's less liquid market discount bonds -- at mid-year.
This was due to our concern about the market's liquidity as we closed in on the
end of the year and Y2K-related issues.

Q: WHAT FACTORS HELPED PERFORMANCE DURING THE YEAR?

A: Shorter duration helped the Fund in the second half. Plus, our credit
research helped us identify opportunities that delivered attractive gains. For
example, we invested in the pre-refunded and housing sectors, in California
state securities, and also in certain high-yield municipal bonds. Two of the
Fund's top performers -- North Carolina housing bonds and Foothill California
Toll Road revenue bonds -- enjoyed improving credit fundamentals and that
boosted their market values.

Q: HOW HAVE YOU POSITIONED THE PORTFOLIO FOR THE PERIOD AHEAD?

A: We believe the economy is still very strong. That could force the Federal
Reserve Board to raise interest rates more aggressively in the year ahead than
they did in 1999. As a result, we remain duration neutral. In other words, we
are neither short nor long compared to other, similar funds. We will continue to
seek opportunities with strong credit fundamentals and good liquidity.

STATE STREET RESEARCH TAX-EXEMPT FUND

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
December 31, 1999

NOTE 1
State Street Research Tax-Exempt Fund (the "Fund"), is a series of State Street
Research Tax-Exempt Trust (the "Trust"), which was organized as a Massachusetts
business trust in December, 1985 and is registered under the Investment Company
Act of 1940, as amended, as an open-end management investment company. The Trust
consists presently of two separate funds: State Street Research Tax-Exempt Fund
and State Street Research New York Tax-Free Fund.

The investment objective of the Fund is to seek a high level of interest income
exempt from federal income taxes. In seeking to achieve its investment
objective, the Fund invests primarily in tax-exempt debt obligations which the
investment manager believes will not involve undue risk.

The Fund offers five classes of shares. Class A shares are subject to an initial
sales charge of up to 4.50% and an annual service fee equal to 0.25% of average
daily net assets. On January 1, 1999, the Fund began offering Class B(1) shares
and continued offering Class B shares but only to current shareholders through
reinvestment of dividends and distributions or through exchanges from existing
Class B accounts of State Street Research funds. Class B(1) and Class B pay
annual distribution and service fees of 1.00% and both classes automatically
convert into Class A shares (which pay lower ongoing expenses) at the end of
eight years. Class B(1) shares are subject to a contingent deferred sales charge
on certain redemptions made within six years of purchase. Class B shares are
subject to a contingent deferred sales charge on certain redemptions made within
five years of purchase. Class C shares are subject to a contingent deferred
sales charge of 1.00% on any shares redeemed within one year of their purchase.
Class C shares also pay annual distribution and service fees of 1.00%. Class S
shares are only offered through certain retirement accounts, advisory accounts
of State Street Research & Management Company (the "Adviser"), an indirect
wholly owned subsidiary of Metropolitan Life Insurance Company ("Metropolitan"),
and special programs. No sales charge is imposed at the time of purchase or
redemption of Class S shares. Class S shares do not pay any distribution or
service fees. The Fund's expenses are borne pro-rata by each class, except that
each class bears expenses, and has exclusive voting rights with respect to
provisions of the plans of distribution, related specifically to that class. The
Trustees declare separate dividends on each class of shares.

The following significant accounting policies are consistently followed by the
Fund in preparing its financial statements, and such policies are in conformity
with generally accepted accounting principles for investment companies.

A. INVESTMENT VALUATION
Tax-exempt securities are valued by a pricing service, which utilizes market
transactions, quotations from dealers, and various relationships among
securities in determining value. Short-term obligations are valued at amortized
cost. Other securities, if any, are valued at their fair value as determined in
accordance with established methods consistently applied.

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.

C. NET INVESTMENT INCOME
Net investment income is determined daily and consists of interest accrued and
discount earned, less amortization of premium and the estimated daily expenses
of the Fund. Interest income is accrued daily as earned. The Fund is charged for
expenses directly attributable to it, while indirect expenses are allocated
between both funds in the Trust.

D. DIVIDENDS
Dividends are declared daily by the Fund based upon projected net investment
income and paid or reinvested monthly. Net realized capital gains, if any, are
distributed annually, unless additional distributions are required for
compliance with applicable tax regulations. For the year ended December 31,
1999, the Fund has designated as long-term $133,630 of the distributions from
net realized gains.

Income dividends and capital gain distributions are determined in accordance
with Federal income tax regulations which may differ from generally accepted
accounting principles.

E. FEDERAL INCOME TAXES
No provision for Federal income taxes is necessary because the Fund has elected
to qualify under Subchapter M of the Internal Revenue Code and its policy is to
distribute all of its taxable income, including net realized capital gains,
within the prescribed time periods. At December 31, 1999, the Fund had a capital
loss carryforward of $2,354,630 available, to the extent provided in
regulations, to offset future capital gains, if any, which expires on December
31, 2007.

In order to meet certain excise tax distribution requirements under Section 4982
of the Internal Revenue Code, the Fund is required to measure and distribute
annually, if necessary, net capital gains realized during a twelve- month period
ending October 31. In this connection, the Fund is permitted to defer into its
next fiscal year any net capital losses incurred between each November 1 and the
end of its fiscal year. From November 1, 1999 through December 31, 1999, the
Fund incurred net capital losses of approximately $521,000 and it intends to
defer and treat such losses as arising in the fiscal year ended December 31,
2000.

F. ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles 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 those 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. 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. During the year ended December 31, 1999, there were no
loaned securities.

NOTE 2
The Trust and the Adviser have entered into an agreement under which the Adviser
earns monthly fees at an annual rate of 0.55% of the Fund's average daily 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, 1999, the fees pursuant to such
agreement amounted to $1,498,106.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), an indirect wholly owned subsidiary of Metropolitan, provides
certain shareholder services to the Fund such as responding to inquiries and
instructions from investors with respect to the purchase and redemption of
shares of the Fund. During the year ended December 31, 1999, the amount of such
expenses was $197,791.

The Fund has entered into an arrangement with its transfer agent whereby credits
realized as a result of invested cash balances were used to reduce a portion of
the Fund's expense. During the year ended December 31, 1999 the Fund's transfer
agent fees were reduced by $15,963 under this arrangement.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$16,458 during the year ended December 31, 1999.

NOTE 3
For the year ended December 31, 1999, purchases and sales of securities,
exclusive of short-term obligations, aggregated $67,651,765 and $98,851,505,
respectively.

NOTE 4
The Trust has adopted plans of distribution pursuant to Rule 12b-1 under the
Investment Company Act of 1940, as amended. Under the plans, the Fund pays
annual service fees to the Distributor at a rate of 0.25% of average daily net
assets for Class A, Class B(1), Class B and Class C shares. In addition, the
Fund pays annual distribution fees of 0.75% of average daily net assets for
Class B(1), Class B and Class C shares. The Distributor uses such payments for
personal services and/or the maintenance or servicing of shareholder accounts,
to reimburse securities dealers for distribution and marketing services, to
furnish ongoing assistance to investors and to defray a portion of its
distribution and marketing expenses. For the year ended December 31, 1999, fees
pursuant to such plans amounted to $493,398, $48,593, $568,851 and $27,497 for
Class A, Class B(1), Class B and Class C shares, respectively.

The Fund has been informed that the Distributor and MetLife Securities, Inc., a
wholly owned subsidiary of Metropolitan, earned initial sales charges
aggregating $101,969 and $332,107, respectively, on sales of Class A shares of
the Fund during the year ended December 31, 1999, and that MetLife Securities,
Inc. earned commissions aggregating $182,705 and $10,153 on sales of Class B
(1), and Class B shares, and the Distributor collected contingent deferred sales
charges aggregating $20,853, $86,755 and $1,429 on redemptions of Class B(1),
Class B and Class C shares, respectively, during the same period.

NOTE 5
The Trustees have the authority to issue an unlimited number of shares of
beneficial interest, $.001 par value per share. At December 31, 1999,
Metropolitan owned 58,578 Class B(1) shares of the Fund.

Share transactions were as follows:

REPORT OF INDEPENDENT ACCOUNTANTS

TO THE TRUSTEES OF STATE STREET RESEARCH
TAX-EXEMPT TRUST AND THE SHAREHOLDERS OF
STATE STREET RESEARCH TAX-EXEMPT FUND

In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolio, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of State Street Research Tax- Exempt
Fund (a series of State Street Research Tax-Exempt Trust, hereafter referred to
as the "Trust") at December 31, 1999, and the results of its operations, the
changes in its net assets and the financial highlights for the periods
indicated, in conformity with accounting principles generally accepted in the
United States. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Trust's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with auditing standards generally accepted in the
United States, which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit 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, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 1999 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE
- --------------------------------------------------------------------------------

State Street Research Tax-Exempt Fund had a challenging year. Class A shares
returned -4.34% for the 12 months ended December 31, 1999 [does not reflect
sales charge]. That was better than the Lipper General Municipal Debt Fund
Average, which lost -4.63%. However, the Fund underperformed the Lehman Brothers
Municipal Bond Index, which returned -2.06% for the same period.

The Fund invests in tax-exempt debt obligations with an emphasis on research to
maximize return and manage risk.

The manager's decision to lengthen duration hurt performance relative to the
Fund's peer group. However, performance was aided by security selection. Credit
research helped the manager identify segments of the market where fundamentals
were improving.

December 31, 1999

Keep in mind that past performance is no guarantee of future results. 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. Performance reflects a
maximum 4.5% Class A share front-end sales charge, or 5% Class B(1) share or
Class B share or 1% Class C share contingent deferred sales charge, where
applicable. The Fund's returns include performance before the creation of share
classes. If this performance reflected the share classes' current 12b-1 fees,
the Fund's returns may have been lower. Class S shares, offered without a sales
charge, are available only through certain employee benefit plans and special
programs. The Lehman Brothers Municipal Bond Index is comprised of 8,000
fixed-rate investment- grade municipal bonds, all from issues larger than $50
million and with maturities greater than two years. The index is unmanaged and
does not take sales charges into consideration. Direct investment in the index
is not possible; results are for illustrative purposes only.

FROM THE CHAIRMAN

[Photo of Ralph F. Verni]

DEAR SHAREHOLDER:

Another good year for the U.S. economy has extended America's cycle of
prosperity to nine consecutive years. Gross domestic product, a measure of goods
and services produced in the U.S., rose at an estimated annual rate of 4.0%.
Personal income has risen and consumer spending has been strong. Inflation
remained relatively low as productivity gains offset wage gains. However, the
Consumer Price Index moved up one full percentage point from 1.6% to 2.6%. The
Federal Reserve Board responded to these indicators of strength by raising
short-term interest rates by 3/4% in three 1/4% steps in the second half of the
year.

STOCKS
The U.S. stock market delivered another year of double-digit gains. The S&P
500(1) rose 21.0% during the 12-month period ended December 31, 1999. However,
S&P 500 technology stocks accounted for a disproportionate share of those gains.
Technology stocks in the S&P 500 gained 74.6%. Non- technology S&P 500 stocks
gained only 4.5%. The technology-heavy Nasdaq gained 85.6% for the year.

BONDS
The bond market was hurt by the Federal Reserve Board's interest-rate hikes and
by factors associated with Y2K. Fears that issuers would go to the market with
their debt issues early in the year drove yields up and bond prices down.
However, those fears were not realized, and the market began to close the yield
gap in the second half of the year. In this environment, mortgage bonds held up
better than government and corporate bonds. High yield bonds finished the year
ahead of other bond sectors, but with modest single-digit results.

INTERNATIONAL
Economic growth around the globe was better than expected. In Asia and certain
emerging markets, economies rebounded from last year's currency woes faster than
anticipated. Japan has shown the first signs of real progress in revitalizing
its economy in nearly a decade. That was reflected in strong stock market
performance for the year, especially among small Japanese companies. Europe
delivered generally favorable results as did the emerging markets of Latin
America.

OUTLOOK AND OPPORTUNITIES
As we enter the year 2000, many markets are poised for growth. However, there
are also areas, such as the technology sector in the U.S., where extraordinarily
high valuations suggest caution in the months ahead. Now is a good time to
consult your financial professional about the strategies that make sense for
your personal portfolio.

And, as always, we thank you for investing in State Street Research.

    Sincerely,

/s/ Ralph F. Verni

    Ralph F. Verni
    Chairman

    December 31, 1999

PORTFOLIO MANAGER'S REVIEW

New York Tax-Free Fund: A challenging environment for municipal bonds


[Photo of Paul Clifford]

       Paul Clifford
     Portfolio Manager

We spoke with Paul Clifford, portfolio manager of State Street Research New York
Tax-Free Fund, about the Fund's performance for the year ended December 31, 1999
and his views on the period ahead.

Q: HOW DID THE FUND PERFORM LAST YEAR?
A: It was a disappointing year for the Fund. Class A shares returned -4.87% for
the 12 months ended December 31, 1999 [does not reflect sales charge].(2) That
was slightly better than the Lipper New York Municipal Debt Funds Average, which
returned -4.89%. However, the Fund underperformed the Lehman Brothers Municipal
Bond Index(1), which returned -2.06% for the same period.

Q: WHAT FACTORS HURT PERFORMANCE IN 1999?
A: During the first five months of the year we lengthened the Fund's duration.
(Duration is a measure of a fund's sensitivity to changing interest rates.) When
interest rates decline, longer duration can help return. However, when interest
rates rise - as they did in 1999 -- it hurts all bond funds, but particularly a
fund with longer duration.

Q: WHY DID YOU LENGTHEN DURATION?
A: At the beginning of 1999, our view was that interest rates were positioned to
decline. However, higher-than- expected economic growth put the Federal Reserve
Board on guard about inflation, and interest rates moved up, not down.

Q: BESIDES INTEREST RATES, WHAT OTHER FACTORS AFFECTED THE MUNICIPAL BOND
   MARKET?
A: In general, New York municipal bond funds were hurt by a poor technical
environment. In other words, there were too many sellers and too few buyers
during most of the year. Liquidity in the market was poor overall as cash flowed
out of many municipal bond funds and into other areas of the market where
investors were attracted to higher returns.

Q: DID YOU SHIFT YOUR STRATEGY AS THE ENVIRONMENT CHANGED?
A: Yes. As it became apparent that the economy was getting stronger, not weaker,
we shortened the Fund's duration. We also improved the portfolio's liquidity -
we sold some of the Fund's less liquid market discount bonds - at mid-year. This
was due to our concern about the market's liquidity as we closed in on the end
of the year.

Q:  WHAT FACTORS HELPED PERFORMANCE DURING THE YEAR?
A: Shorter duration helped the Fund in the second half of the year. Plus, our
credit research helped us identify opportunities that delivered attractive
gains. For example, we invested in New York state mortgage revenue bonds, which
delivered strong performance. The Fund also benefited from its investment in
Syracuse, New York airport bonds. Their credit fundamentals improved over the
year, raising the value of our investment.

Q: HOW HAVE YOU POSITIONED THE PORTFOLIO FOR THE PERIOD AHEAD?
A: We believe the U.S. and New York state economies are still very strong. That
could force the Federal Reserve Board to raise interest rates more aggressively
in the year ahead than they did in 1999. As a result, we remain duration
neutral. In other words, we are neither short nor long compared to other,
similar funds. We will continue to seek opportunities with strong credit
fundamentals and good liquidity.

STATE STREET RESEARCH NEW YORK TAX-FREE FUND

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
December 31, 1999

NOTE 1

State Street Research New York Tax-Free Fund (the "Fund"), is a series of State
Street Research Tax-Exempt Trust (the "Trust"), which was organized as a
Massachusetts business trust in December, 1985 and is registered under the
Investment Company Act of 1940, as amended, as an open-end management investment
company. The Trust consists presently of two separate funds: State Street
Research New York Tax-Free Fund and State Street Research Tax-Exempt Fund.

The investment objective of the Fund is to seek a high level of interest income
exempt from federal income taxes and New York State and New York City personal
income taxes. To achieve its investment objective, the Fund intends to invest
primarily in securities which are issued by or on behalf of New York State or
its political subdivisions and by other governmental entities.

The Fund offers five classes of shares. Class A shares are subject to an initial
sales charge of up to 4.50% and an annual service fee equal to 0.25% of average
daily net assets. On January 1, 1999, the Fund began offering Class B(1) shares
and continued offering Class B shares but only to current shareholders through
reinvestment of dividends and distributions or through exchanges from existing
Class B accounts of State Street Research funds. Class B(1) and Class B pay
annual distribution and service fees of 1.00% and both classes automatically
convert into Class A shares (which pay lower ongoing expenses) at the end of
eight years. Class B(1) shares are subject to a contingent deferred sales charge
on certain redemptions made within six years of purchase. Class B shares are
subject to a contingent deferred sales charge on certain redemptions made within
five years of purchase. Class C shares are subject to a contingent deferred
sales charge of 1.00% on any shares redeemed within one year of their purchase.
Class C shares also pay annual distribution and service fees of 1.00%. Class S
shares are only offered through certain retirement accounts, advisory accounts
of State Street Research & Management Company (the "Adviser"), an indirect
wholly owned subsidiary of Metropolitan Life Insurance Company ("Metropolitan"),
and special programs. No sales charge is imposed at the time of purchase or
redemption of Class S shares. Class S shares do not pay any distribution or
service fees. The Fund's expenses are borne pro-rata by each class, except that
each class bears expenses, and has exclusive voting rights with respect to
provisions of the plans of distribution, related specifically to that class. The
Trustees declare separate dividends on each class of shares.

The following significant accounting policies are consistently followed by the
Fund in preparing its financial statements, and such policies are in conformity
with generally accepted accounting principles for investment companies.

A. INVESTMENT VALUATION
Tax-exempt securities are valued by a pricing service, which utilizes market
transactions, quotations from dealers, and various relationships among
securities in determining value. Short-term obligations are valued at amortized
cost. Other securities, if any, are valued at their fair value as determined in
accordance with established methods consistently applied.

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.

C. NET INVESTMENT INCOME
Net investment income is determined daily and consists of interest accrued and
discount earned, less amortization of premium and the estimated daily expenses
of the Fund. Interest income is accrued daily as earned. The Fund is charged for
expenses directly attributable to it, while indirect expenses are allocated
between both funds in the Trust.

D. DIVIDENDS
Dividends are declared daily by the Fund based upon projected net investment
income and paid or reinvested monthly. Net realized capital gains, if any, are
distributed annually, unless additional distributions are required for
compliance with applicable tax regulations. For the year ended December 31,
1999, the Fund has designated as long-term all of the distributions from net
realized gains.

Income dividends and capital gain distributions are determined in accordance
with Federal income tax regulations which may differ from generally accepted
accounting principles.

E. FEDERAL INCOME TAXES
No provision for Federal income taxes is necessary because the Fund has elected
to qualify under Subchapter M of the Internal Revenue Code and its policy is to
distribute all of its taxable income, including net realized capital gains,
within the prescribed time periods. At December 31, 1999, the Fund had a capital
loss carryforward of $1,037,719 available, to the extent provided in
regulations, to offset future capital gains, if any, which expires on December
31, 2007.

In order to meet certain excise tax distribution requirements under Section 4982
of the Internal Revenue Code, the Fund is required to measure and distribute
annually, if necessary, net capital gains realized during a twelve- month period
ending October 31. In this connection, the Fund is permitted to defer into its
next fiscal year any net capital losses incurred between each November 1 and the
end of its fiscal year. From November 1, 1999 through December 31, 1999, the
Fund incurred net capital losses of approximately $354,000 and it intends to
defer and treat such losses as arising in the fiscal year ended December 31,
2000.

F. FUTURES CONTRACTS
The Fund may enter into futures contracts as a hedge against unfavorable market
conditions and to enhance income. The Fund will not purchase any futures
contract if, after such purchase, more than one-third of net assets would be
represented by long futures contracts. The Fund will limit its risks by entering
into a futures position only if it appears to be a liquid investment.

Upon entering into a futures contract, the Fund deposits with the selling broker
sufficient cash or U.S. Government securities to meet the minimum "initial
margin" requirements. Thereafter, the Fund receives from or pays to the broker
cash or U.S. Government securities equal to the daily fluctuation in value of
the contract ("variation margin"), which is recorded as unrealized gain or loss.
When the contract is closed, the Fund records realized gain or loss equal to the
differences between the value of the contract at the time it was opened and the
value at the time it was closed.

G. ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles 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 those estimates.

H. 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. 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. During the year ended December 31, 1999, there were no
loaned securities.

NOTE 2

The Trust and the Adviser have entered into an agreement under which the Adviser
earns monthly fees at an annual rate of 0.55% of the Fund's average daily 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, 1999, the fees pursuant to such
agreement amounted to $379,165.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), an indirect wholly owned subsidiary of Metropolitan, provides
certain shareholder services to the Fund such as responding to inquiries and
instructions from investors with respect to the purchase and redemption of
shares of the Fund. During the year ended December 31, 1999, the amount of such
expenses was $45,439.

The Fund has entered into an agreement with its transfer agent whereby credits
realized as a result of uninvested cash balances were used to reduce a portion
of the Fund's expense. During the year ended December 31, 1999 the Fund's
transfer agent fees were reduced by $4,676 under this agreement.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$18,615 during the year ended December 31, 1999.

NOTE 3

The Distributor and its affiliates may from time to time and in varying amounts
voluntarily assume some portion of fees or expenses relating to the Fund. During
the year ended December 31, 1999, the amount of such expenses assumed by the
Distributor and its affiliates was $118,819.

NOTE 4

For the year ended December 31, 1999, purchases and sales of securities,
exclusive of short-term obligations, aggregated $29,653,477 and $32,677,975,
respectively.

NOTE 5

The Trust has adopted plans of distribution pursuant to Rule 12b-1 under the
Investment Company Act of 1940, as amended. Under the plans, the Fund pays
annual service fees to the Distributor at a rate of 0.25% of average daily net
assets for Class A, Class B(1), Class B and Class C shares. In addition, the
Fund pays annual distribution fees of 0.75% of average daily net assets for
Class B(1), Class B and Class C shares. The Distributor uses such payments for
personal services and/or the maintenance or servicing of shareholder accounts,
to reimburse securities dealers for distribution and marketing services, to
furnish ongoing assistance to investors and to defray a portion of its
distribution and marketing expenses. For the year ended December 31, 1999, fees
pursuant to such plans amounted to $53,142, $22,209, $171,089 and $8,883 for
Class A, Class B(1), Class B and Class C shares, respectively.

The Fund has been informed that the Distributor and MetLife Securities, Inc., a
wholly owned subsidiary of Metropolitan, earned initial sales charges
aggregating $20,025 and $66,228, respectively, on sales of Class A shares of the
Fund during the year ended December 31, 1999, and that MetLife Securities, Inc.
earned commissions aggregating $98,210 and $3,233 on sales of Class B(1) and
Class B shares, and that the Distributor collected contingent deferred sales
charges aggregating $260, $37,088 and $98 on redemptions of Class B(1), Class B
and Class C shares, respectively, during the same period.

NOTE 6

Under normal circumstances at least 80% of the Fund's net assets will be
invested in New York Municipal Obligations. New York State and New York City
face potential economic problems due to various financial, social, economic and
political factors which could seriously affect their ability to meet continuing
obligations for principal and interest payments. Also, the Fund is able to
invest up to 25% of total assets in a single industry. Accordingly, the Fund's
investments may be subject to greater risk than those in a fund with more
restrictive concentration limits.

NOTE 7

TO THE TRUSTEES OF STATE STREET RESEARCH
TAX-EXEMPT TRUST AND THE SHAREHOLDERS OF
STATE STREET RESEARCH NEW YORK TAX-FREE FUND

In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolio, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of State Street Research New York
Tax-Free Fund (a series of State Street Research Tax-Exempt Trust, hereafter
referred to as the "Trust") at December 31, 1999, and the results of its
operations, the changes in its net assets and the financial highlights for the
periods indicated, in conformity with accounting principles generally accepted
in the United States. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the responsibility of the
Trust's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with auditing standards generally accepted in
the United States, which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit 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, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 1999 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

STATE STREET RESEARCH NEW YORK TAX-FREE FUND

- --------------------------------------------------------------------------------
MANAGEMENT DISCUSSION OF FUND PERFORMANCE
- --------------------------------------------------------------------------------

State Street Research New York Tax-Free Fund had a challenging year. Class A
shares returned -4.87% for the 12 months ended December 31, 1999 [does not
reflect sales charge]. That was slightly better than the Lipper New York
Municipal Debt Funds Average, which returned -4.89%. However, the fund
underperformed the Lehman Brothers Municipal Bond Index, which lost -2.06% for
the same period.

The Fund invests in New York state and city tax-exempt debt obligations with an
emphasis on research to maximize return and manage risk.

The manager's decision to lengthen duration hurt performance relative to the
indices. However, performance was aided by security selection. Credit research
helped the manager identify segments of the New York market where fundamentals
were improving.

December 31, 1999

Keep in mind that past performance is no guarantee of future results. 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. Performance reflects a
maximum 4.5% Class A share front-end sales charge, or 5% Class B(1) share or
Class B share or 1% Class C share contingent deferred sales charge, where
applicable. The Fund's returns include performance before the creation of share
classes. If this performance reflected the share classes' current 12b-1 fees,
the Fund's returns may have been lower. Class S shares, offered without a sales
charge, are available only through certain employee benefit plans and special
programs. The Lehman Brothers Municipal Bond Index is comprised of 8,000
fixed-rate investment-grade municipal bonds, all from issues larger than $50
million and with maturities greater than two years. The index is unmanaged and
does not take sales charges into consideration. Direct investment in the index
is not possible; results are for illustrative purposes only.
