Dear Shareholder: 

We are pleased to provide the annual report for the Smith
Barney Oregon Municipals Fund ("Fund") for the year ended April 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 and Investment Strategy Update
For the year ended April 30, 1998, the Fund's Class A shares returned 9.97%
before the deduction of any sales charges. In comparison, the Fund's Lipper
Analytical Services, Inc. ("Lipper") peer group average had a total return of
8.57% during the same period. (Lipper is an independent fund-tracking
organization.) Performance information for the Fund's other share classes can be
found beginning on page five.


Based on its net asset value ("NAV") of $10.76 as of April 30, 1998, and the
current monthly income distribution rate of $0.043 for Class A shares, the
Fund's annualized distribution rate is 4.80%. For an Oregon investor in a
combined federal and state tax bracket of 41.76%, the Fund's tax-exempt yield of
4.80% is equivalent to a taxable yield of 8.24%. (This figure assumes an
investors is in a federal income tax bracket of 36%.)


During the reporting period, the Fund continued to own mostly good quality,
higher-coupon bonds. In selecting investments for the Fund, we tend to place
greater emphasis on providing current income rather than total return. As of
April 30, 1998, the Fund's dollar-weighted average life was roughly 12 years and
nearly 95% of the Fund's holdings were rated investment grade. (The weighted
average life differs from the average weighted maturity in that it shows the
length of time before the first optional call date rather than the maturity life
of the bond.) In addition, approximately 36% of the Fund's portfolio was rated
AAA, the highest quality bond rating. (Investment-grade bonds are those rated in
one of the four highest ratings categories by any nationally recognized
statistical rating organization, or determined by the manager to be of
equivalent quality.)

Oregon Economic Highlights

Oregon's low level of tax-supported debt and robust economic growth in recent
years has enabled the state to continue to enjoy strong credit ratings. As of
March 30, 1998, Oregon's general obligation bonds were rated in the double-A
category by all three major bond rating services, Moody's, Standard & Poor's and
Fitch IBCA. We remain positive regarding Oregon's long-term economic prospects
relative to the rest of the U.S.

Oregon has been able to accommodate a mandated shift in school funding caused by
the passage of ballot measure 50 last year. (Measure 50 is a "cut and cap"
property tax limitation approved by Oregon voters in May 1997 that preserves tax
relief for property owners.) Despite the cap on local taxes and the fact that
Oregon still must absorb the costs of the new limits imposed on school
districts, the state's sound financial management practices have enabled it to
successfully meet the challenges of maintaining current school funding and
rising prison costs.

Municipal Bond Market and Economic Overview

During the past year, domestic bond market performance was driven primarily by a
healthy economy with low inflation and the uncertainties that continue to cloud
many of the world's major stock markets. Despite robust consumer demand and
labor shortages in many areas, consumer prices remained fairly stable while
wholesale prices for many commodities, particularly oil, actually fell. The
Gross Domestic Product ("GDP"), which measures the total output of goods and
services produced, grew at an annual rate of nearly 4% in 1997 and continued at
about the same rate in the first quarter of 1998.

In late October 1997, the U.S. stock market experienced its first major shock
during its record-setting seven-year rise when the Dow Jones Industrial Average
(a price-weighted average of 30 actively traded blue chip stocks) fell more than
554 points, the largest single-day point drop in stock market history. The stock
market plunge was triggered by concerns that Asia's spreading economic and
financial crisis might eventually impact domestic markets. Despite the ease in
which U.S. and European stock markets recovered from the downturn, many
investors began to shift their attention towards "safe haven" investments such
as U.S. Treasury securities. This renewed demand helped push the yield on the
bellwether 30-year U.S. Treasury bond, which moves in the opposite direction of
its price, to a record low of 5.73% on January 5, 1998.

Just over a year ago, Federal Reserve Board Chairman Alan Greenspan warned
against what he viewed as "irrational exuberance" in financial markets. Since
that time, the economy has continued to expand, the stock market has soared to
even greater heights and in May 1997, unemployment reached its lowest level in
more than 20 years. Yet, inflation has remained subdued. Federal Reserve
policy-makers have made no changes to monetary policy since March 1997.

<PAGE>

Interest rates, as represented by the 30-year U.S. Treasury bond yields, have
dropped for the most part during the reporting period. Similarly, municipal bond
yields have also declined, although not as sharply. One result of these
historically low interest rates has been a record volume of municipal bond
issuance.

In the first quarter of 1998 alone, more than $68 billion of bonds were sold, an
increase of roughly 70% from the same period last year. Many municipalities took
advantage of the low interest rates by refinancing older, higher-coupon bonds.
Moreover, the strength of the economy has filled government coffers and
increased their debt capacity while the economic expansion has accelerated
demand for more infrastructure improvements, many of which have been on hold in
an era of fiscal conservatism.

In our view, this surge in municipal bond supply has created attractive
investment opportunities. The massive issuance volume that we have witnessed
recently has helped keep municipal bond yields from falling as much as their
taxable counterparts. In addition, the oversupply has resulted in a steeper
yield curve than U.S. Treasury securities and consequently created new
investment opportunities, especially in the longer-term issues. (The yield curve
shows the difference between short- and long-term yields.)

Municipal Bond Market Outlook

We remain bullish on the prospects for the municipal bond market in the coming
months. We believe our positive outlook is supported by the following four
factors:

[bullet] The full impact of the Asian crisis on the U.S. economy has yet to be
         realized. Economic strength continued into the first quarter of this
         year, but we attribute much of that to temporary factors such as
         unusually warm weather. As Asian companies attempt to recover, domestic
         companies will face fierce competition and that will tend to hold
         prices down and help to contain any emerging inflationary pressures.

[bullet] The rate of inflation remains historically low. Salomon Smith Barney
         research forecasts a Consumer Price Index increase of approximately a
         1.3% annual rate for 1998, well below the roughly 5.5% annual average
         since 1970.

[bullet] The reduction of the federal budget, which should also reduce the need
         for issuing Treasury securities.

[bullet] A significant possibility that the Asian economic and financial
         recovery will take longer than many investment professionals currently
         anticipate, therefore extending the disinflationary influence on the
         U.S. economy.

In closing, we would like to thank you for your investment in the Smith Barney
Oregon Municipals Fund. We look forward to continuing to help you pursue your
financial goals.

+ Hypothetical illustration of $10,000 invested in Class A shares at inception
  on May 23, 1994, assuming deduction of the maximum 4.00% sales charge at the
  time of investment and reinvestment of dividends and capital gains, if any, at
  net asset value through April 30, 1998. In addition, there is an hypothetical
  illustration of $10,000 invested in Class B shares at inception on May 23,
  1994, assuming deduction of a 4.50% CDSC, which applies if shares are redeemed
  within one year from initial purchase. This CDSC declines by 0.50% the first
  year after purchase and thereafter by 1.00% per year until no CDSC is
  incurred. The Lehman Brothers Municipal Bond Index is a broad based, total
  return index comprised of investment grade, fixed rate municipal bonds
  selected from issues larger than $50 million issued since January 1991. The
  index is unmanaged and is not subject to the same management and trading
  expenses as a mutual fund. The performance of the Fund's other class of shares
  may be greater or less than Class A and B shares' performance indicated on
  this chart, depending on whether greater or lesser sales charges and fees were
  incurred by shareholders investing in the other classes.

  All figures represent past performance and are not a guarantee of future
  results. Investment returns and principal value will fluctuate, and redemption
  values may be more or less than the original cost. No adjustment has been made
  for shareholder tax liability on dividends or capital gains.

* This figure includes the effect of the cash contribution to capital from the
  investment adviser.

Bond Ratings

All ratings are by Standard & Poor's Ratings Service ("Standard & Poor's"),
except those identified by an asterisk(*) are rated by Moody's Investors
Service Inc. ("Moody's"). The definitions of the applicable rating symbols are
set forth below:


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



<TABLE>
<S>        <C><C>
AAA        -- Bonds rated "AAA" have the highest rating assigned by Standard &
              Poor's. 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
              debt 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 debt in this
              category than in higher rated categories.
</TABLE>

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



<TABLE>
<S>        <C><C>
Aaa        -- Bonds that are 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 that are 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 that are 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 that are 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 charactristics as well.
NR    --   Indicates that the bond is not rated by Standard & Poor's or Moody's.

Short-Term Security Ratings


<TABLE>
<S>        <C><C>
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.

Notes to Financial Statements

1. Significant Accounting Policies

Smith Barney Oregon 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 maturing within 60 days are valued at cost plus
accreted discount or minus amortized premium, which approximates value; (d)
gains or losses on the sale of securities are calculated by using the specific
identification method; (e) 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; (f) direct
expenses are charged to the Fund and each class; investment advisory,
administration fees and general fund expenses are allocated on the basis of
relative net assets by class; (g) dividends and distributions to shareholders
are recorded on the ex-dividend date; (h) 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; (i) 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; and (j) 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.

In addition, organization costs have been deferred and are being amortized on a
straight-line method over a five-year period, beginning with the commencement of
the Fund's operations in May 1994.

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

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 and from designated
state income taxes, to retain such tax-exempt status when distributed to the
shareholders of the Fund.

<PAGE>

 Notes to Financial Statements (continued)

Capital gains distributions, if any, are taxable to shareholders, and are
declared and paid at least annually. Additional taxable distributions may be
made if necessary to avoid a Federal excise tax.

4. Investment Advisory Agreement, Administration Agreement and
   Affiliated Transactions
Mutual Management Corp. ("MMC"), formerly known as Smith Barney Mutual Funds
Management Inc., a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH"),
acts as investment adviser to the Fund. The Fund pays MMC an investment advisory
fee calculated at an annual rate of 0.30% of the Fund's average daily net
assets. This fee is calculated daily and paid monthly. MMC waived a portion of
the investment advisory fees for the Fund for the year ended April 30, 1998.

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. MMC waived a portion of its
administration fees for the year ended April 30, 1998.

Smith Barney Inc. ("SB"), another subsidiary of SSBH, acts as distributor of the
Fund's shares. For the year ended April 30, 1998, SB received sales charges of
approximately $37,000 on sales of the Fund's Class A shares.

There is a contingent deferred sales charge ("CDSC") of 4.50% on Class B shares,
which applies if redemption occurs within one year from initial purchase. This
CDSC declines by 0.50% the first year after purchase and thereafter by 1.00% per
year until no CDSC is incurred. Class C shares have a 1.00% CDSC, which applies
if redemption occurs within the first year of purchase. For the year ended April
30, 1998, CDSCs paid to SB for Class B shares were approximately $23,000.

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

interest authorized with par value of $0.001 per share. The Fund has the ability

Independent Auditors' Report

To the Shareholders and Board of Trustees
of the Smith Barney Oregon Municipals Fund:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of the Smith Barney Oregon Municpals Fund as of
April 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 financial highlights for each of the years in the three-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 period from May 23, 1994 (commencement
of operations) to April 30, 1995, were audited by other auditors whose report
thereon, dated June 19, 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 April
30, 1998, by correspondence with the custodian. As to securities purchased or
sold but not yet received or delivered, we performed other appropriate auditing
procedures. 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 the
Smith Barney Oregon Municipals Fund as of April 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 financial highlights for each of
the years in the three-year period then ended, in conformity with generally
accepted accounting principles.
