September 7, 1999

for tax-exempt
income

Dear Shareholder:

Fiscal 1999 was a challenging year
for both taxable and tax-exempt fixed-income investors. Just before our fiscal
year began in August 1998, debt problems in Russia and Brazil, along with
ongoing concerns about recessions in Asia, created strong worldwide demand for
U.S. Treasury bonds. Demand for Treasuries during times of extreme market
turbulence is often referred to as "a flight to quality."
Early in the fall, slower corporate earnings growth also fueled demand for
the relative safety of U.S. government debt. Prices for long-term Treasury bonds
rose, pushing yields lower. As prices for U.S. Treasury bonds moved higher,
municipal bonds seemed to offer exceptional value compared to Treasuries. Later
in the fall, as demand for Treasuries reversed, an abundant supply of municipal
bonds was met with relatively stable demand.
As winter approached, three Federal Reserve interest rate cuts helped to
restore investors' confidence in the U.S. economy and reduce concerns over
global recession. This set the stage for the significant stock market recovery
that started in the fourth quarter of 1998 and through our fiscal year. In the
spring of 1999, the Dow Jones Industrial Average closed above both the 10,000
and 11,000 marks for the first time.
During the spring and summer, fixed-income investments took second billing to
equities. The performance of Treasury bonds suffered through June, as strength
in the domestic economy reduced demand for "safe haven"

WE ARE PLEASED THAT TOTAL RETURNS FOR ALL FOUR OF OUR MINNESOTA MUNICIPAL BOND
FUNDS OUTPERFORMED THEIR RESPECTIVE LIPPER PEER GROUPS.

investments. Municipal bonds weren't such a clear value as they appeared in
spring 1998 when yields on Treasury bonds and municipal bonds were nearly
identical; however, in our view tax-free bonds remained attractive compared to
Treasury securities in early summer. The interest income you receive from
investing in municipal bonds is free from federal income taxes. Some income may
be subject to the alternative minimum tax (AMT) for investors who are subject to
that tax. The AMT is a federal tax designed to ensure that wealthy individuals
and corporations pay at least some income tax. In most states, interest received
from securities issued by government units within the state is also exempt from
state and local taxes.
On June 30, 1999, the Federal Reserve Board raised the Fed Funds rate, its
target rate for overnight loans between banks, by a quarter of a percentage
point, citing the potential for inflationary concerns. The Treasury market
improved as a result, posting solid gains into the first week of July. Although
they have some important differences, municipal bonds typically move in sympathy
with Treasuries, and the muni market improved during this time period as well.
Even U.S. equity indexes hit new records following the rate increase.
(Source: Bloomberg.)
On August 24, 1999, the Federal Reserve again raised interest rates by a
quarter of a percentage point, the second increase in less than two months,
saying the action should help avert inflation while allowing the nation's long
economic expansion to continue. The Dow Jones Industrial Average reacted
favorably to the interest rate increase, reaching an all-time high of 11,326 on
August 25, 1999. (Source: Bloomberg.)
Municipal bonds weathered the volatility in the fixed-income arena better
than Treasuries this past year. The 30-year U.S. Treasury bond yield stood at
6.21%, while 30-year AAA-rated general obligation municipal bonds closed at
5.52% on August 31, 1999. In essence, municipal general obligation bonds were
yielding 89% of what Treasuries were yielding before tax. (Source: Bloomberg.)
Municipal bonds provide even better yield after taxes are taken into account;
the interest income from municipal bonds is free from federal taxes.

Despite increasing yields, municipal bonds, like most fixed instruments, did
not deliver exceptional total return for the fiscal year ending August 31.
Delaware's Minnesota Municipal Bond Funds were no exception--all four Funds were
slightly down for the fiscal year. We are, however, very pleased that total
returns for our four Minnesota Municipal Bond Funds outpaced the returns of
their respective Lipper peer groups.
Please see the Portfolio Manager's Review for a discussion of individual fund
performance.
Looking forward, we believe taxable and tax-exempt bonds may remain in the
shadow of stocks as long as economic growth and the roaring bull market continue
in 1999. However, we still believe fixed-income investments play a vital role in
well-balanced portfolios. Tax-exempt municipal bonds, which your Funds hold,
remain especially popular with investors for good reason. They offer a wide
range of benefits, including:

o Attractive current income free from federal, state and local taxes*
o Relatively dependable income potential
o Wide range of choices, investment quality, maturity and type of bond to fit in
with your investment objectives.

In the pages that follow, your Fund's portfolio manager, Elizabeth H. Howell,
reviews the positioning of your municipal bond funds and provides an outlook for
the remainder of the year.
We thank you for your continued commitment during a difficult year for
fixed-income investors. We also appreciate your confidence in Delaware
Investments.

Sincerely,

Portfolio Manager's Review

Elizabeth H. Howell
Vice President and Senior Portfolio Manager

September 7, 1999

OVERVIEW
In late summer and fall of 1998, state and local governments issued municipal
bonds at near-record levels, led by education, transportation and health care
issues. New U.S. municipal bond issuance reached $285 billion in 1998, second
only to the record $292 billion sold in 1993. (Source: The Bond Buyer.)
This provided us with ample opportunities to select bonds with solid credit
ratings, high current income potential and the possibility of price
appreciation. The large municipal bond supply, however, slightly exceeded
investor demand, which temporarily stifled price gains. This led to
disappointing returns in early 1999.
New bond issuance cooled off considerably over the first three months of
1999, then picked up again. This higher supply was sustained throughout the
summer. Still, total supply to date in the state of Minnesota from January
through August 31, 1999 was down considerably from the same period in fiscal
1998. Mild demand for municipal bonds in the summer kept prices in check, which
meant these securities continued to offer good values relative to Treasury
bonds.
Prices of most fixed-income securities declined this past year as the stock
market grabbed the headlines. Municipal bonds were no exception. Despite a
difficult year, the municipal bond market began gaining luster late in the
summer as the yield gap between municipal bonds and Treasury securities
narrowed.
Less than two weeks after the Federal Reserve raised its Federal Funds
target rate a second time on August 24 (by 0.25%), high-quality municipal bonds
were still looking extraordinarily attractive in our

DESPITE A DIFFICULT YEAR, THE MUNICIPAL BOND MARKET BEGAN GAINING LUSTER LATE IN
THE SUMMER AS THE YIELD GAP BETWEEN MUNICIPAL BONDS AND TREASURY SECURITIES
NARROWED.

view relative to Treasury bonds. As of August 31, 1999, municipal bond investors
were giving up very little yield in return for freedom from certain taxes.
A couple of factors are at play in the improving municipal market:

o Treasury bond supply has been steadily tapering off this past spring and
summer, pushing prices higher. This made Treasuries relatively more expensive
compared to municipal bonds. For nearly two decades, the government securities
market has grown exponentially. The government relied upon Treasuries to help
it finance the nation's $5.5 trillion in debt. Now, with a back-to-back budget
surplus occurring for the first time since 1956 and 1957, Treasury bonds are
becoming relatively scarce. (Source: Bloomberg.)
o Moreover, a robust U.S. economy has improved the credit quality of many
municipal bond jurisdictions, so default risk for high-quality municipal bonds
is relatively low.

In our view, the single biggest factor weighing down municipal bonds now is
the bull market in stocks. Against annual double-digit gains in the stock
market, the yield on municipals tends to look undersized.

DELAWARE TAX-FREE
MINNESOTA FUND
Delaware Tax-Free Minnesota Fund had a total return of -1.06% (Class A shares at
net asset value with distributions reinvested) for the one-year period ended
August 31, 1999.
Although this return was slightly negative for the year, we succeeded in
preserving capital to a greater degree than the average fund in the Lipper
Minnesota Municipal Debt Fund category.
We selected bonds for Delaware Tax-Free Minnesota Fund which we believed had
the potential to improve total return for the portfolio and provide a
competitive income stream. The majority of the Fund's assets were invested in
high-quality health care, housing and power authority issues.
Within these categories, we focused on new bonds with strong credit ratings
that were selling for less than their face value. In fact, none of our bonds
experienced any credit difficulties during this period. We also sought bonds
with at least 10 years of call protection. This helped protect the Fund from the
possibility that bond issuers would pay off their loans early due to falling
interest rates. If bonds are paid off when interest rates fall, we would have to
reinvest the money at lower interest rates.
As of August 31, 1999, Delaware Tax-Free Minnesota Fund's average effective

duration was 8.4 years, almost six months longer than the average duration of
its Lipper peer group. Duration is a common measure of a bond or bond fund's
sensitivity to interest rates. The longer the duration, the more the bond's
price will change for a given increase or decrease in interest rates. Our longer
than average duration allowed us to take advantage of the higher yields offered
by longer term securities.

DELAWARE MINNESOTA
INSURED FUND
Delaware Minnesota Insured Fund had a total return of -0.17% (Class A Shares at
net asset value with distributions reinvested) for the one-year period ended
August 31, 1999. We succeeded in preserving capital to a greater degree than the
Fund's peer group which delivered a -2.70% average return for the same one-year
period.
In fiscal 1999, more than 50% of all new municipal issues carried insurance
according to Securities Data Corporation, up from 23% of all new municipal
issues in fiscal 1998. This demonstrates growing demand for the added security
of insured municipal bonds. The bonds in Delaware Minnesota Insured Fund's
portfolio are protected by private insurance, which guarantees the timely
payment of principal and interest.
Over the last year, 35% of the Fund's holdings were invested in pre-refunded
bonds. Issuers often pre-refund their bonds when interest rates are low in order
to reduce their interest costs. Pre-refunded bonds help the Fund because:

o The credit quality increases. Pre-refunded bonds are backed by investments in
U.S. government bonds, which are held in a separate escrow account.
o The price increases because the bond will be paid off at the first call
option.
o In general, prices for these bonds are less sensitive to interest rate
fluctuations.

In most cases, once a bond is pre-refunded we continue to hold it. This
normally allows the Fund to collect an attractive level of current income and
benefit from better protection of principal. Pre-refunded bonds performed
especially well during the rising interest rate environment we've experienced
the last six months.

August 31, 1999. The Fund modestly outperformed a peer group of municipal bond
funds from a variety of states that invest in intermediate length securities.
This outperformance can be partially explained by the Fund's average
effective duration. As of August 31, 1999, Delaware Tax-Free Minnesota
Intermediate Fund's duration was positioned at 6.1 years, slightly longer than
the average of the Lipper universe of single state intermediate funds. The
Fund's performance was also enhanced by positions in non-rated bonds and
pre-refunded bonds (approximately 34% of the Fund's total assets).
Our secondary goal for Delaware Tax-Free Minnesota Intermediate Fund is a
high tax-free dividend. We believe that intermediate-term bonds in Minnesota
help us achieve this goal by offering an attractive balance between the reduced
price volatility of short-term bonds and higher income potential of longer
bonds.
As with our three other Minnesota funds, we attempted to minimize capital
gains for Delaware Tax-Free Minnesota Intermediate Fund by holding onto bonds
that appreciated in value. Our low-turnover approach to investing helped limit
taxable distributions to our shareholders.
As of the end of your Fund's fiscal year, Delaware Tax-Free Minnesota
Intermediate Fund was the only intermediate state fund to offer dual exempt
income (free from both federal and state taxes) to Minnesota residents.

DELAWARE MINNESOTA HIGH-YIELD MUNICIPAL BOND FUND
Delaware Minnesota High-Yield Municipal Bond Fund provided a total return of
- -0.27% (Class A shares at net asset value with distributions reinvested) for the
year ended August 31, 1999. Although this Fund's one-year performance was
negative, it did surpass the average return of other Minnesota municipal bond
funds, as represented by the Lipper High-Yield Municipal Debt Fund Average. This
average provided an annual return of -1.80% for the year ended August 31, 1999
and is comprised of 54 peer funds.
Over the last year, we increased Delaware Minnesota High-Yield Municipal Bond
Fund's holdings of non-rated bonds. They now represent more than 65% of the
portfolio. In most cases, these bonds were issued by small, rural municipalities
looking to avoid the expense of obtaining a Standard & Poor's rating.
We rigorously research non-rated bond issues before we purchase them and
continue to monitor their credit quality on a regular basis. By investing in
non-rated bonds, which generally offer higher yields, we were able to generate
higher income for Delaware

<PAGE>

income

Minnesota High-Yield Municipal Bond Fund's shareholders. The interest
environment we experienced this past year favored these securities, which have
the potential to deliver greater price stability than highly rated bonds.
The duration of your Fund was 9.8 years as of August 31, 1999, slightly
longer than its peer group. Shareholders also benefited from Delaware Minnesota
High-Yield Municipal Bond Fund's tax-efficient portfolio management. In fiscal
1999, we held onto our appreciated bonds and paid no capital gains.

OUTLOOK
The U.S. seems to be the engine of growth for the entire world at this time. We
believe strong forward momentum for the U.S. economy is likely to result in
solid growth (about 3% annually) for the remainder of this year.
We also believe the Federal Reserve's two rate increases represented
fine-tuning rather than fundamental changes in policy. Both actions were made by
the central bank in an apparent attempt to avert inflation while allowing the
nation's long economic expansion to continue.

OFFER VALUABLE ASSET ALLOCATION BENEFITS WITHOUT ADDING TO TAXABLE INVESTMENT
INCOME.

Having now taken back two of last fall's three rate cuts, the Fed did leave
open the possibility that it could raise rates a third time this year. We
believe they would do so if economic data showed inflationary pressure in the
form of a sharp decline in unemployment, further big wage increases or a
substantial rise in the Consumer Price Index, an index that tracks U.S.
inflationary levels in percentage points.
In the coming year, we think that municipal bond prices have the potential to
rise. Because municipal bonds are generally not subject to the ebb and flow of
foreign demand, like Treasuries, they have been far more stable the last two
years. According to Bloomberg, over the last two years as of August 31, the
price of 10-year Treasuries were three times as volatile as municipal bond
prices based on standard deviation. We believe more investors will flock to
municipal bonds in the months ahead and drive up demand.
If prices rise, state municipal bond mutual funds, such as any of our four
Delaware Minnesota Municipal Bond Funds, have the potential to rise in value. We
see the possibility of attractive capital appreciation considering that
municipal prices would have to rise significantly in order to push their yields
down to historical 85% yield levels as compared to Treasuries.
If U.S. economic growth slows modestly for the remainder of 1999, the Federal
Reserve is less likely to raise short-term rates. Bonds will likely breathe a
sigh of relief and long-term interest rates could fall. From an economic
perspective, we believe inflation remains tame. Municipal bonds, at their
reasonable current prices, should offer investors excellent value in the
remainder of 1999.
Regardless of market conditions, municipal bond funds have the potential to
offer valuable asset allocation benefits without adding to taxable investment
income. In our view, investors seeking to diversify their portfolios with less
volatile investments will find attractive opportunities in municipal bonds and
municipal bond funds.

REGARDLESS OF MARKET CONDITIONS, MUNICIPAL BOND FUNDS HAVE THE POTENTIAL TO
OFFER VALUABLE ASSET ALLOCATION BENEFITS WITHOUT ADDING TO TAXABLE INVESTMENT
INCOME.

grade municipal bonds. The Minnesota High-Yield Municipal Bond Fund seeks high
current income free from both federal and state income taxes by investing in
medium and lower-grade municipal bonds.

1. Significant Accounting Policies
The following accounting policies are in accordance with generally accepted
accounting principles and are consistently followed by the Funds.

Security Valuation--Long-term debt securities are valued by an independent
pricing service and such prices are believed to reflect the fair value of such
securities. Money market instruments having less than 60 days to maturity are
valued at amortized cost, which approximates market value. Other securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Funds' Board
of Directors.

Federal Income Taxes--Each Fund intends to continue to qualify as a regulated
investment company and make the requisite distributions to shareholders.
Accordingly, no provision for federal income taxes has been made in the
financial statements. Income and capital gain distributions are determined in
accordance with federal income tax regulations which may differ from generally
accepted accounting principles.

Class Accounting--Investment income, common expenses and realized and unrealized
gain (loss) on investments are allocated to the various classes of the Funds on
the basis of daily net assets of each class. Distribution expenses relating to a
specific class are charged directly to that class.

Use of 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 at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

Certain expenses of the Funds are paid through "soft dollar" arrangements with
brokers. These transactions are done subject to best price and execution. The
amount of these expenses for the year ended August 31, 1999 were:

Tax-Free Minnesota Fund ........................ $9,940
Minnesota Insured Fund ......................... 6,829
Tax-Free Minnesota Intermediate Fund ........... 1,427
Minnesota High-Yield Municipal Bond Fund ....... 1,375

<PAGE>

The expenses paid under the above arrangement are included in their respective
expense captions in the Statement of Operations with the corresponding expenses
offset shown as "expenses paid indirectly".

Other--Expenses common to all funds within the Delaware Investments Family of
Funds are allocated amongst the funds on the basis of average net assets.
Security transactions are recorded on the date the securities are purchased or
sold (trade date). Costs used in calculating realized gains and losses on the
sale of investment securities are those of the specific securities sold.
Interest income is recorded on the accrual basis. Original issue discounts and
market premium are amortized to interest income over the lives of the respective
securities. The Funds declare dividends from net investment income daily and pay
them monthly. Capital gains, if any, are distributed annually.

2. Investment Management and Other Transactions with Affiliates
In accordance with the terms of the Investment Management Agreement, the Funds
pay Delaware Management Company ("DMC"), the Investment Manager of each Fund, an
annual fee, which is calculated daily on the average daily net assets of each
Fund.

Commencing April 1, 1999, and in accordance with the terms of the Investment
Management Agreement, the Minnesota Insured Fund pays DMC, the Investment
Manager of the Fund, an annual fee which is calculated at the rate of 0.50% on
the first $500 million of average daily net assets of the Fund, 0.475% on the
next $500 million, 0.45% on the next $1,500 million and 0.425% on the average
daily net assets in excess of $2,500 million. The Minnesota High-Yield Municipal
Bond Fund pays DMC, the Investment Manager of the Fund, an annual fee which is
calculated at the rate of 0.55% on the first $500 million of average daily net
assets of the Fund, 0.50% on the next $500 million, 0.45% on the next $1,500
million and 0.425% on the average daily net assets in excess of $2,500 million.

Commencing April 15, 1999, and in accordance with the terms of the Investment
Management Agreement, the Tax-Free Minnesota Fund pays DMC, the Investment
Manager of the Fund, an annual fee which is calculated at the rate of 0.55% on
the first $500 million of average daily net assets of the Fund, 0.50% on the
next $500 million, 0.45% on the next $1,500 million and 0.425% on the average
daily net assets in excess of $2,500 million. The Tax-Free Minnesota
Intermediate Fund pays DMC, the Investment Manager of the Fund, an annual fee
which is calculated at the rate of 0.50% on the first $500 million of average
daily net assets of the Fund, 0.475% on the next $500 million, 0.45% on the next
$1,500 million and 0.425% on the average daily net assets in excess of $2,500
million.

Prior to April 1, 1999, and April 15, 1999, respectively, the Tax-Free Minnesota
Fund and the Minnesota Insured Fund paid DMC an annual fee which was calculated
at the rate of 0.50% of the average daily net assets of the Fund, the Tax-Free
Minnesota Intermediate Fund paid DMC an annual fee which was calculated at the
rate of 0.40% of the average daily net assets of the Fund, and the Minnesota
High-Yield Municipal Bond Fund paid DMC an annual fee which was calculated at

5. Lines of Credit
Committed lines of credit were $21,600,000 for Tax-Free Minnesota Fund,
$14,900,000 for Minnesota Insured Fund, $3,100,000 for Tax-Free Minnesota
Intermediate Fund and $1,600,000 for Minnesota High-Yield Municipal Bond Fund.
No amounts were outstanding at August 31, 1999, or at any time during the fiscal
year.

6. Credit and Market Risk
The Funds concentrate their investments in securities issued by municipalities,
mainly in Minnesota. The value of these investments may be adversely affected by
new legislation within the state, regional or local economic conditions, and
differing levels of supply and demand for municipal bonds. Many municipalities
insure repayment for their obligations. Although bond insurance reduces the risk
of loss due to default by an issuer, such bonds remain subject to the risk that
market value may fluctuate for other reasons and there is no assurance that the
insurance company will meet its obligations. These securities have been
identified in the Statement of Net Assets.

7. Tax Information (Unaudited)
The information set forth is for each Fund's fiscal year as required by federal
laws. Shareholders, however, must report distributions on a calendar year basis
for income tax purposes, which may include distributions for portions of two
fiscal years of a Fund. Accordingly, the information needed by shareholders for
income tax purposes will be sent to them in early 2000. Please consult your tax
advisor for proper treatment of this information.

For the fiscal year ended August 31, 1999, each Fund designates as long term
capital gains, ordinary income and tax-exempt income distributions paid during
the year as follows:

REPORT OF INDEPENDENT AUDITORS
- --------------------------------------------------------------------------------
To the Shareholders and Board of Directors
Voyageur Tax-Free Funds, Inc. - Delaware Tax-Free Minnesota Fund
Voyageur Insured Funds, Inc. - Delaware Minnesota Insured Fund
Voyageur Intermediate Tax-Free Funds, Inc. - Delaware Tax-Free Minnesota
Intermediate Fund
Voyageur Mutual Funds, Inc. - Delaware Minnesota High-Yield Municipal Bond Fund

We have audited the accompanying statements of net assets of Delaware Tax-Free
Minnesota Fund, Delaware Minnesota Insured Fund, Delaware Tax-Free Minnesota
Intermediate Fund and Delaware Minnesota High-Yield Municipal Bond Fund (the
"Funds") as of August 31, 1999, and the related statements of operations for the
year then ended, the statements of changes in net assets for each of the periods
indicated therein, and the financial highlights for each of the periods
presented from January 1, 1997 through August 31, 1999. These financial
statements and financial highlights are the responsibility of the Funds'
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits. The financial
highlights for the periods presented through December 31, 1996 were audited by
other auditors whose reports thereon dated February 14, 1997 expressed
unqualified opinions on those financial highlights.

We conducted our audits in accordance with generally accepted auditing
standards. 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 and financial highlights. Our procedures included confirmation of
securities owned as of August 31, 1999, by correspondence with the custodian and
brokers. 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, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective Funds at August 31, 1999, the results of their operations for
the year then ended, the changes in their net assets for each of the periods
indicated therein, and their financial highlights for each of the periods
presented from January 1, 1997 through August 31, 1999, in conformity with
generally accepted accounting principles.
