Dear Shareholder:

     We are pleased to provide the quarterly report for the Managed Municipal
Portfolio II Inc. ("Fund") for the period ended May 31, 1998. Over the nine
months covered by this report, the Fund distributed income dividends totaling
$0.43 per share. The table below shows the annualized distribution rate and
nine-month total return based on the Fund's May 31, 1998 net asset value ("NAV")
per share and its New York Stock Exchange ("NYSE") closing price.

total return on NAV of 8.20% for the same time period, as reported by Lipper
Analytical Services, Inc. (Lipper is a major fund-tracking organization.)

Municipal Bond Market Update

     The past year under review has seen a clear dichotomy develop between
domestic and international pressures on the bond markets. Recently, the weakness
in Southeast Asia has kept inflationary pressures low and has provided a soft
economic backdrop, which in turn has helped to support bond prices. With respect
to the U.S. economy, the data has been quite different and indicates powerful
economic growth, tight labor markets and some signs of higher inflationary
pressures. These conditions would normally point to a Federal Reserve Board
("Fed") tightening of short-term interest rates and weakening bond prices.
However, Asia's problems have put Fed monetary policy temporarily on hold and
have

created a classic standoff between the bulls and the bears. Some investors may
perceive this standoff as relative calm in a market that is actually more
turbulent than it may appear. While the market may seem calm on the surface,
pressures from both viewpoints are building. We expect that one side will
ultimately prevail and become dominant, probably before the end of the year. In
our opinion, current domestic concerns should outweigh foreign considerations
among Fed policy-makers.

Investment Strategy

     The yield curve has become extremely flat in the last few months. (The
yield curve shows the difference between short- and long-term yields.) That
means there is little extra yield being offered by owning longer maturity bonds
and taking on the added risks of higher interest rate volatility.

     We have attempted to increase the Fund's coupon and decrease its average
maturity from where we were last year. (Coupon is the interest rate on a debt
security the issuer promises to pay to the holder until maturity, expressed as
an annual percentage of face value. Average maturity is a dollar weighted
average maturity of bonds contained in the portfolio.) While this may be a more
conservative investment strategy, for us this appears to be a rare opportunity
to come in shorter on the yield curve in the municipal bond market without any
appreciable sacrifice in the income stream. With today's low interest rates, we
think our strategy is prudent.

     As of May 31, 1998, approximately 82% of the Fund's holdings were rated
investment grade (BBB/Baa and higher) by either Standard & Poor's Ratings Group
or Moody's Investor Service Inc., with about 49% of the Fund invested in AAA/Aaa
bonds, the highest rating. (Investment-grade bonds are those rated in one of the
four highest ratings categories by nationally recognized statistical rating
organization, or determined by the manager to be of equivalent quality.) The
Fund's largest holdings are concentrated in general obligation bonds (11.5%),
transportation bonds (10.6%) and water and sewer bonds (9.7%).

Municipal Bond Market Outlook

     Municipal bonds today trade at approximately 90% of 30-year U.S. Treasury
bonds, which is an extremely attractive after-tax spread. U.S. Treasury bond
rates have been pushed down by several forces, but most recently by foreign
capital exiting Asia in a "flight to quality." Because these foreign investors
do not gain any benefit from tax-exempt income, municipal bonds have not
appreciated as much as U.S.

Treasurys of late. It also means that when the tide turns, the Fund's currently
more defensive investment strategy should hold us in good stead in any future
market sell-off.

     We have also seen a significant increase in the volume of new issues in the
municipal bond market taking advantage of historically low interest rates. We
believe the municipal market is comparatively inexpensive and provides us with a
broad spectrum of securities to choose from. For us, that means the issues we
will consider will probably remain high in credit quality and somewhat shorter
in maturity than in past market cycles.

     In closing, thank you for investing in the Managed Municipals Portfolio II
Inc. We look forward to continuing to help you pursue your financial goals.

Sincerely,



/s/ HEATH B. MCLENDON                   /s/ J.P. DEANE

Take Advantage of the Fund's Dividend Reinvestment Plan!

Did you know that fund investors who reinvest their dividends are taking
advantage of one of the most effective wealth-building tools available today?
Systematic investments put time to work for you through the strength of
compounding.

As an investor in the Fund, you can participate in its Dividend Reinvestment
Plan ("Plan"), a convenient, simple and efficient way to reinvest your dividends
and capital gains, if any, in additional shares of the Fund. The Fund's complete
Plan begins on page 23. Below is a short summary of how the Plan works.

Plan Summary

If you are a Plan participant who has not elected to receive your dividends in
the form of a cash payment, then your dividend and capital gain distributions
will be reinvested automatically in additional shares of the Fund.

The number of common stock shares in the Fund you will receive in lieu of a cash
dividend is determined in the following manner. If the market price of the
common stock is equal to or exceeds the net asset value ("NAV") per share on the
date of valuation, you will be issued shares for the equivalent of the most
recently determined NAV per share or 95% of the market price, whichever is
greater.

If the NAV per share at the time of valuation is greater than the market price
of the common stock, or if the Fund declares a dividend or capital gains
distribution payable only in cash, the Fund will buy common stock for your
account in the open market or on the New York Stock Exchange.

If the Fund begins to purchase additional shares in the open market and the
market price of the shares subsequently rises above the NAV before the purchases
are completed, the Fund will attempt to cancel any remaining orders and issue
the remaining dividend or distribution in shares at the Fund's NAV per share. In
that case, the number of Fund shares you receive will be based on the weighted
average of prices paid for shares purchased in the open market and the price at
which the Fund issues the remaining shares.

To find out more detailed information about the Dividend Reinvestment Plan and
about how you can participate, please call First Data Investors Services Group
at (800) 331-1710.

                                  Bond Ratings
                                   (unaudited)
================================================================================

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 "BB" 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 differ 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 they are 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   --   Bonds rated "BB" have less near-term vulnerability to default than
          other speculative issues. However, it faces major ongoing
          uncertainties or exposure to adverse business, financial, or economic
          conditions which could lead to inadequate capacity to meet timely
          interest and principal payments.

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 is 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.


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

================================================================================

SP-1   -- Standard & Poor's highest rating indicating very strong or strong
          capacity to pay principal and interest; those issued determined
          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.

A-2    -- Standard & Poor's second highest commercial paper and 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

     Managed Municipals Portfolio II Inc. ("Fund"), a Maryland corporation, is
registered under the Investment Company Act of 1940, as amended, as a
non-diversified, closed-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 bid and asked prices provided by an independent
pricing service that are based on transactions in municipal obligations,
quotations from municipal bond dealers, market transactions in comparable
securities and various relationships between securities; (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) dividends and distributions to shareholders are
recorded on the ex-dividend date; (g) 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 August 31, 1997,
reclassifications were made to undistributed net investment income and
accumulated net realized gains to reflect permanent book/tax differences and
income and gains available for distributions under income tax regulations. Net
investment income, net realized gains and net assets were not affected by this
change; (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; and (i) 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. 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.

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

     3. 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 an advisory fee calculated at an annual rate of 0.70% of the average daily
net assets of the Fund. 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. This fee
is calculated daily and paid monthly.

     All officers and one Director of the Fund are employees of Smith Barney
Inc., another subsidiary of SSBH.

     4. Investments

     For the nine months ended May 31, 1998, the aggregate cost of purchases and
proceeds from sales of investments (including maturities, but excluding
short-term securities) were as follows:

<TABLE>

================================================================================

     5.  Futures Contracts

     Initial margin deposits made upon entering into futures contracts are
recognized as assets. Securities equal to the initial margin amount are
segregated by the custodian in the name of the broker. Additional securities are
also segregated up to the current market value of the futures contracts. During
the period the futures contract is open, changes in the value of the contract
are recognized as unrealized gains or losses by "marking-to-market" on a daily
basis to reflect the market value of the contract at the end of each day's
trading. Variation margin payments are made or received and recognized as assets
due from or liabilities due to broker, depending upon whether unrealized gains
or losses are incurred. When the contract is closed, the Fund records a realized
gain or loss equal to the difference between the proceeds from (or cost of) the
closing transactions and the Fund's basis in the contract.

     The Fund enters into such contracts to hedge a portion of its portfolio.
The Fund bears the market risk that arises from changes in the value of the
financial instruments and securities indices (futures contracts).

     At May 31, 1998, the Fund had no open futures contracts.

     6. Repurchase Agreements

     The Fund purchases (and its custodian takes possession of) U.S. government
securities from banks and securities dealers subject to agreements to resell the
securities to the sellers at a future date (generally, the next business day) at
an agreed-upon higher repurchase price. The Fund requires continual maintenance
of the market value of the collateral in amounts at least equal to the
repurchase price.

     7. Capital Shares

     During the year ended August 31, 1997, capital stock transactions were as
follows:

                           Dividend Reinvestment Plan
                                   (unaudited)
================================================================================
 
     Under the Fund's Dividend Reinvestment Plan ("Plan"), a shareholder whose
shares of Common Stock are registered in his or her own name will have all
distributions from the Fund reinvested automatically by First Data Investor
Services Group, Inc. ("First Data") as purchasing agent under the Plan, unless
the shareholder elects to receive cash. Distributions with respect to shares
registered in the name of a broker-dealer or other nominee (that is, in "street
name") will be reinvested by the broker or nominee in additional shares under
the Plan, unless the service is not provided by the broker or nominee or the
shareholder elects to receive distributions in cash. Investors who own Common
Stock registered in street name should consult their broker-dealers for details
regarding reinvestment. All distributions to Fund shareholders who do not
participate in the Plan will be paid by check mailed directly to the record
holder by or under the direction of First Data as dividend-paying agent.

     The number of shares of Common Stock distributed to participants in the
Plan in lieu of a cash dividend is determined in the following manner. Whenever
the market price of the Common Stock is equal to or exceeds the net asset value
per share on the date of valuation, Plan participants will be issued shares of
Common Stock at a price equal to the greater of (1) the net asset value per
share most recently determined or (2) 95% of the market price.

     If the net asset value per share of Common Stock at the time of valuation
exceeds the market price of the Common Stock, or if the Fund declares a dividend
or capital gains distribution payable only in cash, First Data will buy Common
Stock in the open market, on the NYSE or elsewhere, for the participants'
accounts. If, following the commencement of the purchases and before First Data
has completed its purchases, and the market price exceeds the net asset value of
the Common Stock, First Data will attempt to terminate purchases in the open
market and cause the Fund to issue the remaining portion of the dividend or
distribution by issuing shares at a price equal to the greater of (a) net asset
value or (b) 95% of the then current market price. In this case, the number of
shares of Common Stock received by a Plan participant will be based on the
weighted average of prices paid for shares purchased in the open market and the
price at which the Fund issues the remaining shares. To the extent First Data is
unable to stop open market purchases and cause the Fund to issue the remaining
shares, the average per share purchase price paid by First Data may exceed the
net asset value of the Common Stock, resulting in the acquisition of fewer
shares than if the dividend or capital gains distribution had been paid in
Common Stock issued by the Fund at net asset value. First Data will begin to
purchase Common Stock on the open market as soon as practicable after the
payment date of the dividend or capital gains distribution, but in no event
shall such purchases

continue later than 30 days after that date, except when necessary to comply
with applicable provisions of the Federal securities laws.

     First Data maintains all shareholder accounts in the Plan and furnishes
written confirmations of all transactions in each account, including information
needed by a shareholder for personal and tax records. The automatic reinvestment
of dividends and capital gains distributions will not relieve Plan participants
of any income tax that may be payable on the dividends or capital gains
distributions. Common Stock in the account of each Plan participant, will be
held by First Data in uncertificated form in the name of each Plan participant.

     Plan participants are subject to no charge for reinvesting dividends and
capital gains distributions under the Plan. First Data's fees for handling the
reinvestment of dividends and capital gains distributions will be paid by the
Fund. No brokerage charges apply with respect to shares of Common Stock issued
directly by the Fund under the Plan. Each Plan participant will, however, bear a
proportionate share of brokerage commissions incurred with respect to any open
market purchases made under the plan.

     Experience under the Plan may indicate that changes to it are desirable.
The Fund reserves the right to amend or terminate the Plan as applied to any
dividend or capital gains distribution paid subsequent to written notice of the
change sent to participants at least 30 days before the record date for the
dividend or capital gains distribution. The Plan also may be amended or
terminated by First Data, with the Fund's prior written consent, on at least 30
days' written notice to Plan participants. All correspondence concerning the
Plan should be directed by mail to First Data Investor Services Group, P.O. Box
8030, Boston, Massachusetts 02266-8030 or by telephone at 1-800-331-1710.

                               ------------------

     Notice is hereby given in accordance with Section 23(c) of the Investment
Company Act of 1940, as amended, that from time to time the Fund may purchase
shares of its common stock in the open market.
