Dear Shareholder:

We are pleased to provide the annual report for the Smith Barney Massachusetts
Municipals Fund ("Fund") for the year ended November 30, 1998. In this report,
we summarize the period's prevailing economic and market conditions and outline
our portfolio strategy. A detailed summary of the Fund's performance can be
found in the appropriate sections that follow.

Performance Update

For the year ended November 30, 1998, the Class A shares of the Massachusetts
Municipals Fund returned 7.66% and outperformed the 6.82% return for
Massachusetts tax-exempt funds according to Lipper Inc. for the same period.
(Lipper is an independent fund-tracking organization.) For performance
information on the Fund's other share classes, please refer to pages four and
five.

During the period covered by this report, the Fund distributed income dividends
totaling $0.65 and a capital gain distribution of $0.20 per Class A share. Based
on its net asset value ("NAV") of $13.32 as of November 30, 1998 and current
income dividend rate of $0.054 per share, this equates to annualized
distribution rate of 4.86%. For a Massachusetts state resident in the combined
federal and state tax bracket of 39.28%, the tax-free yield of 4.86% is
equivalent to a taxable yield of 8.00%. (This figure assumes an investor is in
the federal income tax bracket of 31%.)

Market and Economic Overview

With stock market volatility on the rise and anxiety about the global economy
increasing in early fall, the Federal Reserve Board ("Fed") changed its monetary
policy from one of vigilance against inflation to one of combating deflation
during the period under review. (Deflation is when prices actually fall.
Deflation should not be confused with disinflation. Disinflation is the slowing
down of the rate at which prices increase.)

The bond markets have been impacted by numerous significant events this past
year including the turmoil in many emerging markets, Russia's default and the

release of a large number of conflicting economic statistics. A key turning
point for the markets took place on October 17, 1998, when Fed Chairman
Greenspan announced that the federal-funds and discount rates would both be cut
by 25 basis points. (A basis point is a means of expressing yield as a
percentage. Each basis point is 1/100 of 1%. The federal-funds rate is an
overnight bank lending rate that is a benchmark for other short-term interest
rates.) This was the third rate cut by the Fed in recent months and the changes
in the capital markets after that rate cut were significant.

The prices of many U.S. stocks have gone up and liquidity in many sectors of the
bond market has improved dramatically. As investors turned away from U.S.
Treasuries, which are the most liquid and least risky of all bonds, their yields
went back up sharply. For example, the yield on the 30-year Treasury increased
by more than 65 basis points from October 5, 1998 through November 6, 1998. And
just as other types of bonds had underperformed as U.S. Treasury rates declined,
they outperformed as Treasury rates rebounded.

During the reporting period, municipal bond yields did not drop as quickly as
U.S. Treasury yields on the way down and they did not go up as quickly as U.S.
Treasury yields during the subsequent rebound in rates. For example, while
30-year Treasury yields went up by about 50 basis points from October 1, 1998
through November 5, 1998, long-term municipal bond yields went up by only
roughly 20-23 basis points. Despite these differences, we still believe
municipal bonds are attractively priced in comparison with taxable bonds.

Heavy new issuance of municipal bonds combined with modest demand for tax-exempt
income are the main reasons why municipal bonds are so inexpensive now on a
historical basis. New cash into bond funds has been low, the demand for
municipal bonds from property and casualty companies has been moderate and many
individual investors have remained on the sidelines because of the stock
market's recent strong rebound.

Massachusetts Economic Highlights

Although Massachusetts was negatively impacted by the last recession, the
Commonwealth's economy in recent years has grown strongly and we think its
long-term outlook remains positive. The economy of Massachusetts is well
diversified and continues to generate high personal income levels. Moreover, we
anticipate that the Commonwealth's well-established trend of strong fiscal
control and solid budget performance should hold it in good stead and solidify
its leadership position in the Northeast as we enter the next century.

Investment Strategy

The Fund's investment strategy continues to seek to provide Massachusetts
investors with as high a level of dividend income exempt from federal and

Massachusetts personal income taxes as is consistent with prudent investment
management and the preservation of capital. In addition, we strive to maintain a
high-quality portfolio. As of November 30, 1998, over 91% of the Fund's holdings
were rated investment grade or better, of which approximately 48% were rated
triple-A by either Standard & Poor's Ratings Service or Moody's Investors
Service Inc. At the end of the reporting period, the Fund's average weighted
maturity was roughly 21 years. In addition, as of November 30, 1998, the Fund's
top three sectors were general obligation bonds (21.9%), hospital bonds (21.4%)
and transportation (18.2%).

Municipal Bond Market Outlook

During 1998, the performance of the U.S. economy has helped propel state tax
collections higher and add to their strong fiscal positions. As previously
noted, the volume of new municipal issues remains heavy as attractive low
interest rates continue to provide an incentive for state and local governments
to refinance older, high interest rate debt. On the other hand, demand for
tax-exempt income remains modest. Given this strong supply and moderate demand,
it is not surprising that municipal bonds are inexpensive by historical
standards. At current yield levels, we believe municipal bonds make sense for
many investors.

Going forward, we are optimistic about the attractiveness of the tax-exempt bond
market. And while we expect no more Fed policy moves for the remainder of the
year, we believe that the Fed may lower rates again in the first half of 1999 if
the U.S. economy remains sluggish.

In closing, thank you for your investment in the Smith Barney Massachusetts
Municipals Fund. We look forward to helping you pursue your investment goals.

Sincerely,


/s/ Heath B. McLendon                    /s/ Lawrence T. McDermott

Bond Ratings (unaudited)
- --------------------------------------------------------------------------------

The definitions of the applicable rating symbols are set forth below:

Standard & Poor's Ratings Services ("Standard & Poor's") -- Ratings from "AA" to
"B" may be modified by the addition of a plus (+) or minus (-) sign to show
relative standings within the major rating categories.

AAA      -- Bonds rated "AAA" have the highest rating assigned by Standard &
            Poor's to a debt obligation. Capacity to pay interest and repay
            principal is extremely strong.

AA       -- Bonds rated "AA" have a very strong capacity to pay interest and
            repay principal and differs from the highest rated issue only in a
            small degree.

A        -- Bonds rated "A" have a strong capacity to pay interest and repay
            principal although it is somewhat more susceptible to the adverse
            effects of changes in circumstances and economic conditions than
            bonds in higher rated categories.

BBB      -- Bonds rated "BBB" are regarded as having an adequate capacity to
            pay interest and repay principal. Whereas they normally exhibit
            adequate protection parameters, adverse economic conditions or
            changing circumstances are more likely to lead to a weakened
            capacity to pay interest and repay principal for bonds in this
            category than in higher rated categories.

BB and B -- Bonds rated "BB" and "B" are regarded, on balance, as predominantly 
            speculative with respect to capacity to pay interest and repay
            principal in accordance with the terms of the obligation. "BB"
            represents a lower degree of speculation than "B". While such bonds
            will likely have some quality and protective characteristics, these
            are outweighed by large uncertainties or major risk exposures to
            adverse conditions.

Moody's Investors Service Inc. ("Moody's") -- Numerical modifiers 1, 2 and 3 may
be applied to each generic rating from "Aa" to "B," where 1 is the highest and 3
the lowest ranking within its generic category.

Aaa      -- Bonds rated "Aaa" are judged to be of the best quality. They carry 
            the smallest degree of investment risk and are generally referred to
            as "gilt edge." Interest payments are protected by a large or by an
            exceptionally stable margin and principal is secure. While the
            various protective elements are likely to change, such changes as
            can be visualized are most unlikely to impair the fundamentally
            strong position of such issues.

Aa       -- Bonds rated "Aa" are judged to be of high quality by all standards. 
            Together with the "Aaa" group they comprise what are generally known
            as high grade bonds. They are rated lower than the best bonds
            because margins of protection may not be as large in Aaa securities
            or fluctuation of protective elements may be of greater amplitude or
            there may be other elements present which make the long-term risks
            appear somewhat larger than in Aaa securities.

A        -- Bonds rated "A" possess many favorable investment attributes and are
            to be considered as upper medium grade obligations. Factors giving
            security to principal and interest are considered adequate but
            elements may be present which suggest a susceptibility to impairment
            some time in the future.

Baa      -- Bonds rated "Baa" are considered as medium grade obligations, i.e., 
            they are neither highly protected nor poorly secured. Interest
            payments and principal security appear adequate for the present but
            certain protective elements may be lacking or may be
            characteristically unreliable over any great length of time. Such
            bonds lack outstanding investment characteristics and in fact have
            speculative characteristics as well.

Ba       -- Bonds rated "Ba" are judged to have speculative elements; their
            future cannot be considered as well assured. Often the protection of
            interest and principal payments may be very moderate thereby not
            well safeguarded during both good and bad times over the future.
            Uncertainty of position characterizes bonds in this class.

B        -- Bonds rated "B" generally lack characteristics of desirable
            investments. Assurance of interest and principal payments or of
            maintenance of other terms of the contract over any long period of
            time may be small.

NR       -- Indicates that the bond is not rated by Standard & Poor's or 
            Moody's.

Short-Term Security Ratings (unaudited)
- --------------------------------------------------------------------------------

SP-1     -- Standard & Poor's highest rating indicating very strong or strong
            capacity to pay principal and interest; those issues determined to
            possess overwhelming safety characteristics are denoted with a plus
            (+) sign.

A-1      -- Standard & Poor's highest commercial paper and variable-rate demand 
            obligation (VRDO) rating indicating that the degree of safety
            regarding timely payment is either overwhelming or very strong;
            those issues determined to possess overwhelming safety
            characteristics are denoted with a plus (+) sign.

VMIG 1   -- Moody's highest rating for issues having a demand feature -- VRDO. 

P-1      -- Moody's highest rating for commercial paper and for VRDO prior to 
            the advent of the VMIG 1 rating.

1. Significant Accounting Policies

Smith Barney Massachusetts Municipals Fund ("Fund"), a Massachusetts business
trust, is registered under the Investment Company Act of 1940, as amended, as a
non-diversified, open-end management investment company.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities are valued
at the mean between the quoted bid and ask prices provided by an independent
pricing service; (c) securities for which market quotations are not available
will be valued in good faith at fair value by or under the direction of the
Board of Trustees; (d) securities maturing within 60 days are valued at cost
plus accreted discount or minus amortized premium, which approximates value; (e)
gains or losses on the sale of securities are calculated by using the specific
identification method; (f) interest income, adjusted for amortization of premium
and accretion of original issue discount, is recorded on an accrual basis;
market discount is recognized upon the disposition of the security; (g) direct
expenses are charged to each class; management fees and general fund expenses
are allocated on the basis of relative net assets; (h) dividends and
distributions to shareholders are recorded on the ex-dividend date; (i) the Fund
intends to comply with the applicable provisions of the Internal Revenue Code of
1986, as amended, pertaining to regulated investment companies and to make
distributions of taxable income sufficient to relieve it from substantially all
Federal income and excise taxes; (j) the character of income and gains to be
distributed are determined in accordance with income tax regulations which may
differ from generally accepted accounting principles. At November 30, 1998,
reclassifications were made to the Fund's capital accounts to reflect permanent
book/tax differences and income and gains available for distributions under
income tax regulations. Accordingly, a portion of overdistributed net investment
income amounting to $62,219 was reclassified to paid-in capital. Net investment
income, net realized gains and net assets were not affected by this adjustment;
and (k) estimates and assumptions are required to be made regarding assets,
liabilities and changes in net assets resulting from operations when financial
statements are prepared. Changes in the economic environment, financial markets
and any other parameters used in determining these estimates could cause actual
results to differ.

2. Fund Concentration

Since the Fund invests primarily in obligations of issuers within the
Commonwealth of Massachusetts, it is subject to possible concentration risks
associated with economic, political or legal developments or industrial or
regional matters specifically affecting Massachusetts.

3. Exempt-Interest Dividends and Other Distributions

The Fund intends to satisfy conditions that will enable interest from municipal
securities, which is exempt from regular Federal income tax, to retain such
tax-exempt status when distributed to the shareholders of the Fund.

Capital gains distributions, if any, are taxable to shareholders, and are
declared and paid at least annually.

4. Investment Advisory Agreement, Administration Agreement and Other
   Transactions

Mutual Management Corp. ("MMC"), a subsidiary of Salomon Smith Barney Holdings
Inc. ("SSBH"), acts as investment adviser to the Fund. The Fund pays MMC a fee
calculated at an annual rate of 0.30% of its average daily net assets. This fee
is calculated daily and paid monthly.

MMC also acts as the Fund's administrator for which the Fund pays a fee
calculated at an annual rate of 0.20% of the average daily net assets up to $500
million and 0.18% of the average daily net assets in excess of $500 million.
This fee is calculated daily and paid monthly.

On October 8, 1998, CFBDS, Inc., became the Fund's distributor. Prior to that
date, Salomon Smith Barney Inc. ("SSB"), another subsidiary of SSBH, was the
Fund's distributor. SSB, as well as certain other broker-dealers, continues to
sell Fund shares to the public as a member of the selling group.

On June 12, 1998, the Fund's existing Class C shares were renamed Class L
shares. Effective June 15, 1998, Class L shares are being sold at net asset
value plus a maximum initial sales charge of 1.00%. Class L shares also have a
1.00% contingent deferred sales charge ("CDSC"), which applies if redemption
occurs within the first year of purchase.

There is also a CDSC of 4.50% on Class B shares, which applies if redemption
occurs within one year from purchase. This CDSC declines by 0.50% the first year
after purchase and thereafter by 1.00% per year until no CDSC is incurred.

For the year ended November 30, 1998, SSB received sales charges of $103,000 and
$3,000 on sales of the Fund's Class A and Class L shares, respectively. In
addition, CDSC's paid to SSB were approximately:

                                                         Class B       Class L
================================================================================
CDSCs                                                    $39,000        $1,000
================================================================================

Pursuant to a Distribution Plan, the Fund pays a service fee with respect to its
Class A, B and L shares calculated at an annual rate of 0.15% of the average
daily net assets of each respective class. In addition, the Fund pays a
distribution fee with respect to its Class B and L shares calculated at an
annual rate of 0.50% and 0.55%, respectively, of the average daily net assets of
each class. For the year ended November 30, 1998, total Distribution Plan fees
incurred were:

                                         Class A        Class B       Class L

6. Shares of Beneficial Interest

At November 30, 1998, the Fund had an unlimited number of shares of beneficial
interest authorized with a par value of $0.001 per share. The Fund has the
ability to issue multiple classes of shares. Each share of a class represents an
identical interest and has the same rights, except that each class bears certain
direct expenses, including those specifically related to the distribution of its
shares. Effective June 12, 1998, the Fund adopted the renaming of existing Class
C shares as Class L shares.

Independent Auditors' Report
- --------------------------------------------------------------------------------

The Shareholders and Board of Trustees of
Smith Barney Massachusetts Municipals Fund:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of the Smith Barney Massachusetts Municipals Fund
as of November 30, 1998, the related statement of operations for the year then
ended, the statements of changes in net assets for each of the years in the
two-year period then ended and the financial highlights for each of the years in
the four-year 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 the year ended November 30,
1994, were audited by other auditors whose report thereon, dated January 12,
1995, expressed an unqualified opinion 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. Our procedures included confirmation of securities owned as of
November 30, 1998, by correspondence with the custodian. As to securities
purchased but not yet received, we performed other appropriate auditing
procedures. An audit also includes assessing the accounting principals 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 the
Smith Barney Massachusetts Municipals Fund as of November 30, 1998, the results
of its operations for the year then ended, the changes in its net assets for
each of the years in the two-year period then ended and the financial highlights
for each of the years in the four-year period then ended, in conformity with
generally accepted accounting principles.
