[picture of Barbara Krumsiek, no caption]

Dear Shareholders:

Investors' risk tolerance was tested in 1998. Global financial turmoil
contributed to a high level of market volatility. By the end of the third
quarter, most equity investors were looking at negative results for the
year-to-date. The fourth quarter brought fast relief, however, with stock
market indices bouncing back to provide investors with a fourth consecutive
year of double-digit gains. Price appreciation was an integral component of
bond returns, as yields generally declined throughout the year.

Among stocks, the top performers were tightly consolidated by capitalization
range and industry group. Large-capitalization companies and technology
plays fueled most of the advance. In the bond market, long-term U.S.
Treasury securities outperformed other categories substantially.

While investors may be tempted to chase the current trend setters, that
approach comes with increased risk now, given the stock market's high levels
and increased volatility. We encourage investors to make decisions based on
their financial objectives and tolerance for risk. At this point, it would
be a good idea to reevaluate your asset allocation to be sure you are
positioned at a comfortable risk level. If you think change is in order,
your financial professional can suggest strategies that keep you on track to
meet long-term financial objectives without exposing you to undue levels of
risk.

We appreciate your investment in Calvert Group funds and look forward to
providing competitive returns in the year ahead.

Sincerely,

/s/

Barbara J. Krumsiek
President and CEO

National Municipal seeks to earn the highest level of interest income exempt
from federal income taxes, and each state specific fund seeks to earn the
highest level of interest income exempt from federal and specific state
income taxes, as is consistent with prudent investment management,
preservation of capital, and the quality and maturity objectives of each
Fund.

CALVERT MUNICIPAL
INTERMEDIATE FUNDS

Could you describe the investment climate during this period?

Sectors of the U.S. economy showed signs of strength, but, absent clear
signs of inflation, interest rates remained low. Financial troubles in Asia,
Russia and Latin America set off a flight to quality, with investors seeking
the safety of U.S. issued debt securities, primarily Treasuries.

The Federal Reserve maintained its neutral monetary policy until late in
September, when worsening conditions abroad threatened the liquidity of
financial markets worldwide. In three separate moves, the Fed lowered the
federal funds rate, a key overnight bank lending rate, by a total of 75
basis points.

Would you discuss relative performance and strategy for each of the
municipal portfolios?

National Intermediate
The Fund returned 5.46% for the year, a bit above the 5.34% return for the
average intermediate-term municipal debt fund tracked by Lipper. The
positive performance was largely due to the greater number of non-callable
issues in the portfolio. Investors paid a premium for non-callables during
this period, and since we have been accumulating bonds with this structure
for several years, we were rewarded nicely.

In 1999, one of the key factors in our ability to implement our strategy
will be the amount, size and quality of issues coming to market. Issuance
was robust in 1998, but municipals' historically wide spreads relative to
Treasuries still kept a number of issuers out of the market. We'll be
evaluating our holdings as they near maturity and assessing the investment
opportunities presented by new and secondary market issues. At this point,
we expect to keep the Fund's weighted average duration (a measure of the
portfolio's interest rate sensitivity) long, relative to our benchmark.

California Intermediate
The Fund returned 5.51% for the year, in line with the 5.53% return for the
Lipper average.

The performance was the result of the Fund's structure and duration
management. We took profits on some of our lower credit quality holdings,
after these rose in price, and reinvested the proceeds in high-grade issues.
We kept the duration near the long end of our target range. We also
benefited from positions in non-callable bonds. These commanded premium
prices throughout the third quarter.

After a period of muted demand, the California municipal market is thriving
again. Demand was high in 1998 and investors paid a premium for almost every
California issue. As long as the California economy remains strong, demand
for municipal issues should also remain strong.

<PAGE>

If issuance gets way out of line, the premium individuals are willing to pay
could disappear. At this point, we expect to manage the Fund with a longer
than average duration.

Maryland Intermediate
The Fund returned 4.88% for the year, trailing the 5.05% return on the
Lipper Other States Municipal Funds Average. The Fund earned very strong
returns in the third quarter, which almost fully compensated for the weaker
results from the first part of the year.

During the second half, we benefited from a slightly longer than average
core duration and exposure to non-callable bonds in the 12- to 14-year
maturity range. A longer duration indicates greater interest rate
sensitivity; thus, when bond yields moved lower in the third quarter, the
effect on the Fund's net asset value was more favorable.

Maryland municipalities should continue to be successful in bringing new
issues to market, as we expect high-quality issues will continue to be
popular with investors in 1999. At this point, we plan to manage the Fund
with a slightly longer duration, relative to its peer group. We'll also be
evaluating spreads across the spectrum of available issues in an attempt to
identify and profit from undervalued sectors.

Virginia Intermediate
The Fund's total return for the year was 4.88%, which was a bit below the
5.05% return for the average comparable fund tracked by Lipper. The Fund
lagged during the first half of the year and led during the second half.
Unfortunately, our strong performance in the second half could not
completely close the gap.

The Fund was rewarded in the second half for having a slightly longer
duration than that of our peers and for holding a significant number of
non-callable bonds, issues for which investors paid a premium. The longer a
bond's duration, the more its price rises in response to a decline in rates.
We also benefited from the sale of some underperforming housing issues. We
reinvested the proceeds in issues in other sectors.

We'll be monitoring supply and demand conditions carefully in 1999. In
recent years, Virginia debt issuance has been well under the volume cap.
That should not change; however, there are a number of infrastructure
projects in the works that will require significant funding.

What's your outlook?

No one can be sure the troubled Asian or Latin American economies are fully
out of the woods or that another global crisis won't emerge. For this
reason, the financial markets are likely to remain very volatile.

At this point, we think there is a likelihood the Fed will cut rates

<PAGE>

at some point in 1999. At the present time, commodity inflation remains in
check; however, wage inflation is starting to squeeze corporate profits.
This could lead to a slowing of the pace of growth of corporate earnings and
a shift away from the equity markets. We will continue to assess the
strength of the domestic economy and the impact of tumultuous events
occurring in other countries and markets. We'll act quickly to modify our
approach should our forecast change.

We appreciate your investment. Conflicting reports on the strength of the
economy and the meltdown of currencies overseas have created a very
challenging investment environment.

To the Board of Directors and Shareholders of Calvert Municipal Fund, Inc:

In our opinion, the accompanying statements of net assets and the related
statements of operations, statements of changes in net assets and financial
highlights present fairly, in all material respects, the financial position
of Calvert National, California, Maryland, and Virginia Municipal
Intermediate Funds (four portfolios comprising Calvert Municipal Fund, Inc.,
hereafter referred to as the "Funds"), at December 31, 1998, the results of
each of their operations, the changes in each of their net assets and the
financial highlights for each of the periods presented, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Fund'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
generally accepted auditing standards 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, 1998 by correspondence with
custodian and brokers, provide a reasonable basis for the opinion expressed
above.

NOTES TO FINANCIAL STATEMENTS

Note A -- Significant Accounting Policies

General: The Calvert Municipal Fund is comprised of four Municipal
Intermediate Portfolios: National, California, Maryland, and Virginia. Each
of the Portfolios, collectively the "Fund," are registered under the
Investment Company Act of 1940 as open-end management investment companies.
The operations of each Portfolio are accounted for separately. Shares of
each Portfolio are sold with a maximum front-end sales charge of 2.75%.

On March 31, 1998, the net assets of First Variable Rate for Government
Income, Florida Intermediate Portfolio and Calvert Municipal Fund's Michigan
Portfolio and New York Intermediate Portfolios merged into Calvert Municipal
Fund National Intermediate Portfolio. The acquisition was accomplished by a
tax-free exchange of 1,625,516 shares of the National Portfolio (valued at
$17,458,044) for 1,308,624 shares of Florida Portfolio, 893,727 shares of
Michigan Portfolio, and 1,233,997 shares of New York Intermediate Portfolios
outstanding at March 31, 1998. The Florida Portfolio's net assets at that
date, including $15,706 of unrealized appreciation and $3,480 of realized
loss, were combined with those of the National Portfolio. The Michigan
Portfolio's net assets at that date, including $202,434 of unrealized
appreciation and $107,674 of realized loss were combined with those of the
National Portfolio. The New York Portfolio's net assets at that date,
including $97,040 of unrealized appreciation and $1,071 of realized loss
were combined with those of the National Portfolio. The aggregate net assets
of the National Portfolio, Florida Portfolio, Michigan Portfolio, and New
York Portfolio immediately before the acquisition were $49,805,260,
$6,582,381, $4,656,320 and $6,219,343, respectively.

On April 24, 1998, the net assets of the Calvert Municipal Fund's Arizona
and Pennsylvania Intermediate Portfolios merged into Calvert Municipal Fund
National Intermediate Portfolio. The acquisition was accomplished by a
tax-free exchange of 663,385 shares of the National Portfolio (valued at
$7,071,683) for 480,634 shares of Arizona Portfolio and 944,242 shares of
Pennsylvania Portfolio outstanding at April 24, 1998. The Arizona
Portfolio's net assets at that date, including $10,493 of unrealized
appreciation and $1,029 of realized loss, were combined with those of the
National Portfolio. The Pennsylvania Portfolio's net assets at that date,
including $21,951 of unrealized appreciation and $2,521 of realized loss
were combined with those of the National Portfolio. The aggregate net assets
of the National Portfolio, Arizona Portfolio and Pennsylvania Portfolio
immediately before the acquisition were $66,384,068, $2,359,913 and
$4,711,770, respectively.

Security Valuation: Municipal securities are valued utilizing the average of
bid prices or at bid prices based on a matrix system (which considers such
factors as security prices, yields, maturities and ratings) furnished by
dealers through an independent pricing service. Securities (including
options) listed or traded on a national securities exchange are valued at
the last reported sale price. Other securities and assets for which market
quotations are not available or deemed inappropriate are valued in good
faith under the direction of the Board of Directors/Trustees.

Options: The Fund may write or purchase options. The option premium is the
basis for recognition of unrealized or realized gain or loss on the option.
The cost of securities acquired or the proceeds from securities sold through
the exercise of the option is adjusted by the amount of the premium. Risks
from writing or purchasing option securities arise

<PAGE>

from possible illiquidity of the options market and the movement in the
value of the investment or in interest rates. The risk associated with
purchasing options is limited to the premium originally paid.

Futures Contracts: The Fund may enter into futures contracts agreeing to buy
or sell a financial instrument for a set price at a future date. The Fund
maintains securities with a value equal to its obligation under each
contract. Initial margin deposits of either cash or securities are made upon
entering into futures contracts; thereafter, variation margin payments are
made or received daily reflecting the change in market value. Unrealized or
realized gains and losses are recognized based on the change in market
value. Risks of futures contracts arise from the possible illiquidity of the
futures markets and the movement in the value of the investment or in
interest rates.

Security Transactions and Investment Income: Security transactions are
accounted for on trade date. Realized gains and losses are recorded on an
identified cost basis. Interest income, accretion of discount and
amortization of premium are recorded on an accrual basis.

Distributions to Shareholders: Distributions to shareholders are recorded by
the Fund on ex-dividend date. Dividends from net investment income are paid
monthly. Distributions from net realized capital gains, if any, are paid at
least annually. Distributions are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles;
accordingly, periodic reclassifications are made within the Fund's capital
accounts to reflect income and gains available for distribution under income
tax regulations.

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.

Expense Offset Arrangements: The Fund has an arrangement with its custodian
bank whereby the custodian's and transfer agent's fees may be paid
indirectly by credits earned on the Fund's cash on deposit with the bank.
Such a deposit arrangement is an alternative to overnight investments.

Federal Income Taxes: No provision for federal income or excise tax is
required since the Fund intends to continue to qualify as a regulated
investment company under the Internal Revenue Code and to distribute
substantially all of its earnings.

Note B -- Related Party Transactions

capital gains until
expiration.

As a cash management practice, Portfolios may sell or purchase short-term
variable rate demand notes from other Portfolios managed by the Advisor. All
transactions are executed at independently derived prices.

<PAGE>

Note D -- Line of Credit

A financing agreement is in place with all Calvert Group Funds and State
Street Bank and Trust Company ("the Bank"). Under the agreement, the Bank is
providing an unsecured line of credit facility, in the aggregate amount of
$50 million ($25 million committed and $25 million uncommitted), to be
accessed by the Funds for temporary or emergency purposes only. Borrowings
under this facility bear interest at the overnight Federal Funds Rate plus
 .50% per annum. A commitment fee of .10% per annum will be incurred on the
unused portion of the committed facility which will be allocated to all
participating funds. This fee is paid quarterly in arrears. The Fund had no
loans outstanding pursuant to this line of credit at December 31, 1998.

Note E -- Subsequent Event

Calvert Asset Management Company, Inc. (the "Advisor") is wholly-owned by
Calvert Group, Ltd. ("Calvert"), which is indirectly wholly-owned by Acacia
Mutual Holding Corporation ("Acacia Mutual"). Effective January 1, 1999,
Acacia Mutual merged with Ameritas Mutual Insurance Holding Company to form
Ameritas Acacia Mutual Holding Company.

CALVERT GROUP AND THE YEAR 2000
PLANS AND PROGRESS

We are now less than a year away from the year 2000, a problematic date for
computer systems coded for two-character year format. Entered as "00," the
year 2000 would be processed as 1900, a mistake that could foul a variety of
date-sensitive transactions.

As your mutual fund sponsor, our goal is make sure there is no interruption
in the level of service you receive. In the summary below, we've outlined
the steps Calvert Group is taking to ensure our systems perform reliably.

Step One--Assess Systems and Software. Develop an Action Plan.
In 1997, we identified all systems, operating platforms and software
potentially affected by the millennium bug. These included:

         Calvert Group systems--portfolio trading, sales contact and
reporting and internal management reporting
         transfer agency systems--shareholder record-keeping and transaction
processing
         subadvisor systems--investment accounting
         other third-party data and service systems.

We also formed a Y2K task force, led by Calvert's vice president of
technology. This group has identified and prioritized our efforts to achieve
year 2000 compliance.

Step Two--Test for Compliance. Repair Systems as Necessary.
Internal systems have been tested. We've made repairs and moved modified
code into production. These systems are now fully compliant. Transfer agency
systems were re-engineered for compliance in 1989. Recent tests indicate
these are, in fact, compliant. The readiness of third-party systems,
including subadvisor systems, has been evaluated. Based on information
received from these groups, we have found no significant obstacles to
compliance.

Step Three--Confirm Compliance. Finalize Contingency Plan.
Testing of transfer agency systems will continue through 1999 to ensure
these remain compliant and continue to interact correctly with external
systems and processes. The transfer agency has established a back-up site,
should main systems fail, and compliance testing of these contingency
measures are also underway. We are developing contingency plans to ensure
that any unforeseen systems failures will not adversely affect our
operations or inconvenience our shareholders.
