R. JAY GERKEN, CFA
Chairman, President and
Chief Executive Officer

Dear Shareholder,

Bond investors spent much of the six months ended April 30, 2004 dissecting
language from the Federal Reserve for clues on its assessment of the U.S.
economy. During this time, the economy's quarterly pace of growth continued to
advance at a moderate rate that significantly exceeded levels in early 2003.(i)
Even the labor market, which generated lackluster results over most of the
period, grew significantly in March by some measures.(ii) On a local level,
state-tax revenues remained stronger versus the first half of last year.

The combination of stronger economic growth and recent comments from the Fed
exacerbated bond investors' concerns about the course of interest rates. As a
result the yields on municipal bonds, which move opposite to their prices, rose
over the period following their sharp spike in April.(iii) However, given that
the fund's manager had anticipated that the U.S. economy could begin to pick up,
the manager maintained a defensive posture in managing the fund's exposure to
interest rate sensitivity. Although this approach detracted from the fund's
performance during times when bond prices rose, it diminished the downward
pricing pressures on the portfolio when bond prices declined, such as in April.

Your fund returned 1.61%, based on its New York Stock Exchange ("NYSE") market
price and 2.47% based on its net asset value ("NAV")(iv) per share during the
six months ended April 30. In comparison, the unmanaged Lehman Brothers
Municipal Bond Index(v) returned 1.19% and its Lipper high-yield municipal debt
closed-end funds category average was 3.09% over the same time frame.(vi) Please
note that Lipper performance returns are based on each fund's NAV.

During this six-month period, the fund distributed dividends to shareholders
totaling $0.28 per share. The performance table shows the fund's 30-day SEC and
annualized distribution yields as well as its six-month total return based on
its NAV and market price as of April 30, 2004. Past performance is not
indicative of future results. The fund's yields will vary.

All figures represent past performance and are not a guarantee of future
results. The fund's yields will vary.

Total returns are based on changes in NAV or market price, respectively. Total
returns assume the reinvestment of all dividends and/or capital gains
distributions, if any, in additional shares. Annualized distribution yield is
the fund's current monthly income dividend rate, annualized, and then divided by
the NAV or the market price noted in this report. The annualized distribution
yield assumes a current monthly income dividend rate of $0.0455 for 12 months.
The "SEC yield" is a return figure often quoted by bond and other fixed income
mutual funds. This quotation is based on the most recent 30-day (or one month)
period covered by the fund's filings with the SEC. The yield figure reflects the
dividends and interest earned during the period after deduction of the fund's
expenses for the period. These yields are as of April 30, 2004 and are subject
to change.
--------------------------------------------------------------------------------

requests, but are not in a position to predict the outcome of these requests and
investigations.

The information provided is not intended to be a forecast of future events, a
guarantee of future results or investment advice. Views expressed may differ
from those of the firm as a whole.

RISKS: The fund may use derivatives, such as options and futures, which can be
illiquid, may disproportionately increase losses, and have a potentially large
impact on fund performance. High yield bonds involve greater credit and
liquidity risks than investment grade bonds. Certain investors may be subject to
the Federal Alternative Minimum Tax (AMT), and state and local taxes may apply.
Capital gains, if any, are fully taxable.

All index performance reflects no deduction for fees, expenses or taxes. Please
note that an investor cannot invest directly in an index.

      shares, which may be more or less than the fund's NAV.

Take Advantage of the Fund's Dividend Reinvestment Plan!

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. A more complete
description of the Plan begins on page 28. 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 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 shares is equal
to or higher than 98% of the net asset value ("NAV") per share on the date of
valuation, you will be issued shares for the equivalent of either 98% of the
most recently determined NAV per share or 95% of the market price, whichever is
greater.

If 98% of the NAV per share at the time of valuation is greater than the market
price of the common stock, the Fund will buy shares 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 98% of 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 98% of 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 Plan and about how you can
participate, please call PFPC Inc. at 1 (800) 331-1710.

[CLIP ART]                                              Bond Ratings (unaudited)
================================================================================

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

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

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 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 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, B, CCC, -- Bonds rated "BB", "B", "CCC", "CC" and "C" are regarded, on
CC and C       balance, as predominantly speculative and 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", and "C" the highest degree of speculation.
               While such bonds will likely have some quality and protective
               characteristics, these are outweighed by large uncertainties or
               major risk exposures to adverse conditions.
D           -- Bond rated "D" are in default, and payment of interest and/or
               repayment of principal is in arrears.

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

[CLIP ART]                                  Bond Ratings (unaudited) (continued)
================================================================================

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 many long period
               of time may be small.
Caa         -- Bonds rated "Caa" are of poor standing. These issues may be in
               default, or there may be present elements of danger with respect
               to principal or interest.
Ca          -- Bonds rated "Ca" represent obligations which are speculative in a
               high degree. Such issues are often in default or have other
               marked shortcomings.
C           -- Bonds rated "C" are the lowest rated class of bonds, and issues
               so rated can be regarded as having extremely poor prospects of
               ever attaining any real investment standing.

Fitch Ratings ("Fitch") -- Ratings from "A" to "CCC" may be modified by the
addition of a plus (+) or a minus (-) sign to show relative standings with the
major ratings categories.

AAA         -- Bonds rated "AAA" by Fitch have the lowest expectation of credit
               risk. The obligor has an exceptionally strong capacity for timely
               payment of financial commitments which is highly unlikely to be
               adversely affected by foreseeable events.
A           -- Bonds rated "A" have a low expectation of credit risk. The
               capacity for timely payment of financial commitments is
               considered strong. This capacity may, nevertheless, be more
               vulnerable to changes in circumstances or in economic conditions
               than is the case for higher ratings.
BBB         -- Bonds rated "BBB" currently have a low expectation of credit
               risk. The capacity for timely payment of financial commitments is
               considered to be adequate. Adverse changes in economic conditions
               and circumstances, however, are more likely to impair this
               capacity. This is the lowest investment grade category assigned
               by Fitch.
BB          -- Bonds rated "BB" carry the possibility of credit risk developing,
               particularly as the result of adverse economic change over time.
               Business or financial alternatives may, however, be available to
               allow financial commitments to be met. Securities rated in this
               category are not considered by Fitch to be investment grade.
CCC,        -- Bonds rated "CCC", "CC" and "C" carry the real possibility of

[CLIP ART]                             Notes to Financial Statements (unaudited)
================================================================================

      1. Significant Accounting Policies

      Municipal High Income Fund Inc. ("Fund"), a Maryland corporation, is
registered under the Investment Company Act of 1940, as amended, as a
diversified, closed-end management investment company.

      The following are significant accounting policies consistently followed by
the Fund and are in conformity with generally accepted accounting principles
("GAAP"): (a) security transactions are accounted for on trade date; (b)
securities are valued at the mean between the 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; securities
with no readily obtainable market quotations are valued in good faith at fair
value by or under the direction of the Fund's Board of Directors; (c) securities
maturing within 60 days or less 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
discount, is recorded on an accrual basis; (f) dividends and distributions to
shareholders are recorded on the ex-dividend date; (g) in accordance with
Statement of Position 93-2 Determination, Disclosure, and Financial Statement
Presentation of Income, Capital Gain, and Return of Capital Distributions by
Investment Companies, book and tax basis differences relating to shareholder
distributions and other permanent book and tax differences are reclassified to
paid-in capital. In addition, the character of income and gains to be
distributed is determined in accordance with income tax regulations which may
differ from U.S. generally accepted accounting principles; (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.

      In addition, the Fund invests in high-yield instruments that are subject
to certain credit and market risks. The yields of high-yield debt obligations
reflect, among other things, perceived credit risk. The Fund's investment in
securities rated below investment-grade typically involve risks not associated
with higher rated securities including, among others, greater risk of timely and
ultimate payment of interest and principal, greater market price volatility and
less liquid secondary market trading.

      2. Exempt-Interest Dividends and Other Distributions

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


                                       21


                                                 Municipal High Income Fund Inc.
[CLIP ART]                 Notes to Financial Statements (unaudited) (continued)
================================================================================

      It is the Fund's policy to distribute dividends monthly. 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

      Smith Barney Fund Management LLC ("SBFM"), an indirect wholly-owned
subsidiary of Citigroup Inc. ("Citigroup"), acts as investment adviser to the
Fund. The Fund pays SBFM an investment advisory fee calculated at an annual rate
of 0.40% of the Fund's average daily net assets. SBFM also acts as the
administrator of the Fund for which it receives a fee calculated at an annual
rate of 0.20% of the Fund's average daily net assets. These fees are calculated
daily and paid monthly.

      All officers and one Director of the Fund are employees of Citigroup or
its affiliates.

      4. Investments

      During the six months ended April 30, 2004, the aggregate cost of
purchases and proceeds from sales of investments (including maturities of
long-term investments, but excluding short-term investments) were as follows:

Purchases ........................................................  $ 22,229,632
                                                                    ============

      At April 30, 2004, the aggregate gross unrealized appreciation and
depreciation of investments for Federal income tax purposes were substantially
as follows:

Gross unrealized appreciation ...................................  $  3,999,151
Gross unrealized depreciation ...................................   (21,238,504)
                                                                   ------------
Net unrealized depreciation .....................................  $(17,239,353)

      5. Futures Contracts

      Securities or cash equal to the initial margin amount are either deposited
with the broker or segregated by the custodian upon entering into the futures
contract. 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
received or made 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 typically
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.

      7. Additional Information

      The Fund has received the following information from Citigroup Asset
Management ("CAM"), the Citigroup business unit which includes the Fund's
Investment Manager and other investment advisory companies, all of which are
indirect, wholly-owned subsidiaries of Citigroup. CAM is reviewing its entry,
through an affiliate, into the transfer agent business in the period 1997-1999.
As CAM currently understands the facts, at the time CAM decided to enter the
transfer agent business, CAM sub-contracted for a period of five years certain
of the transfer agency services to a third party and also concluded a revenue
guarantee agreement with this sub-contractor providing that the sub-contractor
would guarantee certain benefits to CAM or its affiliates (the "Revenue
Guarantee Agreement"). In connection with the subsequent purchase of the
sub-contractor's business by an affiliate of the current sub-transfer agent
(PFPC Inc.) used by CAM on many of the funds it manages, this Revenue Guarantee
Agreement was amended eliminating those benefits in exchange for arrangements
that included a one-time payment from the sub-contractor.

      The Boards of CAM-managed funds (the "Boards") were not informed of the
Revenue Guarantee Agreement with the sub-contractor at the time the Boards
considered and approved the transfer agent arrangements. Nor were the Boards
informed of the subsequent amendment to the Revenue Guarantee Agreement when
that occurred.

      CAM has begun to take corrective actions. CAM will pay to the applicable
funds approximately $17 million (plus interest) that CAM and its affiliates
received from the Revenue Guarantee Agreement and its amendment. CAM also plans
an independent review to verify that the transfer agency fees charged by CAM
were fairly priced as compared to competitive alternatives. CAM is instituting
new procedures and making changes designed to ensure no similar arrangements are
entered into in the future.

[CLIP ART]                 Notes to Financial Statements (unaudited) (continued)
================================================================================

      CAM has briefed the SEC, the New York State Attorney General and other
regulators with respect to this matter, as well as the U.S. Attorney who is
investigating the matter. CAM is cooperating with governmental authorities on
this matter, the ultimate outcome of which is not yet determinable.

      The Fund's transfer agent is PFPC Inc., which is not affiliated with CAM.

(1)   For the six months ended April 30, 2004 (unaudited).
(2)   Effective November 1, 2001, the Fund adopted a change in the accounting
      method that requires the Fund to amortize premiums and accrete all
      discounts. Without the adoption of this change, for the year ended October
      31, 2002, the ratio of net investment income to average net assets would
      have been 6.80%. Per share information, ratios and supplemental data for
      the periods prior to November 1, 2001 have not been restated to reflect
      this change in presentation. In addition, the impact of this change to net
      investment income and net realized and unrealized loss was less than $0.01

                                                 Municipal High Income Fund Inc.
[CLIP ART]                                Dividend Reinvestment Plan (unaudited)
================================================================================

      The Fund's policy, which may be changed by the Fund's Board of Directors,
is generally to make monthly distributions of substantially all its net
investment income (i.e., income other than net realized capital gains) to the
holders of the Fund's capital shares. From time to time, when the Fund makes a
substantial capital gains distribution, it may do so in lieu of paying its
regular monthly dividend. Net income of the Fund consists of all income accrued
on portfolio assets less all expenses of the Fund. Expenses of the Fund are
accrued each day. Net realized capital gains, if any, will be distributed to
shareholders at least once a year.

      Under the Fund's Dividend Reinvestment Plan ("Plan"), a shareholder whose
capital shares is registered in his or her own name will have all distributions
reinvested automatically by PFPC Inc. ("PFPC"), 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 capital shares registered in street name should consult their
broker-dealers for details regarding reinvestment. All distributions to
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 PFPC, as
dividend-paying agent.

      The number of shares of capital shares 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 98% of net asset
value ("NAV") per share on the determination date (generally, the record date
for the distribution), participants will be issued shares of common stock valued
at the greater of (1) 98% of the NAV or (2) 95% of the market price. To the
extent that the Fund issues shares to participants in the Plan at a discount to
NAV, the interests of remaining shareholders (i.e., those who do not participate
in the Plan) in the Fund's net assets will be proportionately diluted.

      If 98% of the NAV per share of the capital shares at the time of valuation
(which is the close of business on the determination date) exceeds the market
price of capital shares, PFPC will buy capital shares in the open market, on the
NYSE or elsewhere, for the participants' accounts. If, following the
commencement of the purchases and before PFPC has completed its purchases, the
market price exceeds 98% of what the NAV per share of the capital shares was at
the valuation time, PFPC 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 (1) 98% of the
NAV per share as of the valuation time, or (2) 95% of the then current market
price. In this case, the number of shares of capital shares 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 PFPC is unable to stop open market purchases


                                       28



                                                 Municipal High Income Fund Inc.
[CLIP ART]                    Dividend Reinvestment Plan (unaudited) (continued)
================================================================================

and cause the Fund to issue the remaining shares, the average per share price
paid by PFPC may exceed 98% of the NAV per share of the capital shares. PFPC
will begin to purchase capital shares 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.

      PFPC 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. Capital shares in the account of each Plan participant will be
held by PFPC in uncertificated form in the name of the Plan participant.

      Plan participants are subject to no charge for reinvesting dividends and
capital gains distributions under the Plan. PFPC's fees for handling the
reinvestment of dividends and capital gains distributions will be paid by the
Fund. No brokerage charges shall apply with respect to shares of capital shares
issued directly by the Fund under the Plan. Each Plan participant will, however,
bear a pro-rata share of brokerage commissions actually 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 PFPC or the Fund on at least 30 days' written notice to Plan
participants. All correspondence concerning the Plan should be directed by mail
to PFPC Inc., P.O. Box 43027, Providence, Rhode Island 02940-3027 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 at
market prices shares of its capital shares in the open market. For the six
months ended April 30, 2004, the Fund has not repurchased any shares.

ITEM 7.    DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
           MANAGEMENT INVESTMENT COMPANIES.

           The Board of Directors of the Fund has delegated the authority to
           develop policies and procedures relating to proxy voting to the
           Manager. The Manager is part of Citigroup Asset Management ("CAM"), a
           group of investment adviser affiliates of Citigroup, Inc.
           ("Citigroup"). Along with the other investment advisers that comprise
           CAM, the Manager has adopted a set of proxy voting policies and
           procedures (the "Policies") to ensure that the Manager votes proxies
           relating to equity securities in the best interest of clients.

           In voting proxies, the Manager is guided by general fiduciary
           principles and seeks to act prudently and solely in the best interest
           of clients. The Manager attempts to consider all factors that could
           affect the value of the investment and will vote proxies in the
           manner that it believes will be consistent with efforts to maximize
           shareholder values. The Manager may utilize an external service
           provider to provide it with information and/or a recommendation with
           regard to proxy votes. However, such recommendations do not relieve
           the Manager of its responsibility for the proxy vote.

           In the case of a proxy issue for which there is a stated position in
           the Policies, CAM generally votes in accordance with such stated
           position. In the case of a proxy issue for which there is a list of
           factors set forth in the Policies that CAM considers in voting on
           such issue, CAM votes on a case-by-case basis in accordance with the
           general principles set forth above and considering such enumerated
           factors. In the case of a proxy issue for which there is no stated
           position or list of factors that CAM considers in voting on such
           issue, CAM votes on a case-by-case basis in accordance with the
           general principles set forth above. Issues for which there is a
           stated position set forth in the Policies or for which there is a
           list of factors set forth in the Policies that CAM considers in
           voting on such issues fall into a variety of categories, including
           election of directors, ratification of auditors, proxy and tender
           offer defenses, capital structure issues, executive and director



           compensation, mergers and corporate restructurings, and social and
           environmental issues. The stated position on an issue set forth in
           the Policies can always be superseded, subject to the duty to act
           solely in the best interest of the beneficial owners of accounts, by
           the investment management professionals responsible for the account
           whose shares are being voted. Issues applicable to a particular
           industry may cause CAM to abandon a policy that would have otherwise
           applied to issuers generally. As a result of the independent
           investment advisory services provided by distinct CAM business units,
           there may be occasions when different business units or different
           portfolio managers within the same business unit vote differently on
           the same issue.

           In furtherance of the Manager's goal to vote proxies in the best
           interest of clients, the Manager follows procedures designed to
           identify and address material conflicts that may arise between the
           Manager's interests and those of its clients before voting proxies on
           behalf of such clients. To seek to identify conflicts of interest,
           CAM periodically notifies CAM employees (including employees of the
           Manager) in writing that they are under an obligation (i) to be aware
           of the potential for conflicts of interest with respect to voting
           proxies on behalf of client accounts both as a result of their
           personal relationships and due to special circumstances that may
           arise during the conduct of CAM's and the Manager's business, and
           (ii) to bring conflicts of interest of which they become aware to the
           attention of compliance personnel. The Manager also maintains and
           considers a list of significant relationships that could present a
           conflict of interest for the Manager in voting proxies. The Manager
           is also sensitive to the fact that a significant, publicized
           relationship between an issuer and a non-CAM affiliate might appear
           to the public to influence the manner in which the Manager decides to
           vote a proxy with respect to such issuer. Absent special
           circumstances or a significant, publicized non-CAM affiliate
           relationship that CAM or the Manager for prudential reasons treats as
           a potential conflict of interest because such relationship might
           appear to the public to influence the manner in which the Manager
           decides to vote a proxy, the Manager generally takes the position
           that non-CAM relationships between Citigroup and an issuer (e.g.
           investment banking or banking) do not present a conflict of interest
           for the Manager in voting proxies with respect to such issuer. Such
           position is based on the fact that the Manager is operated as an
           independent business unit from other Citigroup business units as well
           as on the existence of information barriers between the Manager and
           certain other Citigroup business units.

           CAM maintains a Proxy Voting Committee, of which the Manager
           personnel are members, to review and address conflicts of interest
           brought to its attention by compliance personnel. A proxy issue that
           will be voted in accordance with a stated position on an issue or in
           accordance with the recommendation of an independent third party is
           not brought to the attention of the Proxy Voting Committee for a
           conflict of interest review because the Manager's position is that to
           the extent a conflict of interest issue exists, it is resolved by
           voting in accordance with a pre-determined policy or in accordance
           with the recommendation of an independent third party. With respect
           to a conflict of interest brought to its attention, the



           Proxy Voting Committee first determines whether such conflict of
           interest is material. A conflict of interest is considered material
           to the extent that it is determined that such conflict is likely to
           influence, or appear to influence, the Manager's decision-making in
           voting proxies. If it is determined by the Proxy Voting Committee
           that a conflict of interest is not material, the Manager may vote
           proxies notwithstanding the existence of the conflict.

           If it is determined by the Proxy Voting Committee that a conflict of
           interest is material, the Proxy Voting Committee is responsible for
           determining an appropriate method to resolve such conflict of
           interest before the proxy affected by the conflict of interest is
           voted. Such determination is based on the particular facts and
           circumstances, including the importance of the proxy issue and the
           nature of the conflict of interest. Methods of resolving a material
           conflict of interest may include, but are not limited to, disclosing
           the conflict to clients and obtaining their consent before voting, or
           suggesting to clients that they engage another party to vote the
           proxy on their behalf.

                      30a- 3(c) under the Investment Company Act of 1940, as

                      half-year in the case of an annual report) that have
                      materially affected, or are likely to materially affect
