Dear Shareholder,

The bond markets experienced a pullback over the last six months amid signs of a
strengthening economy and renewed inflationary pressures, and rising interest
rates. After a four-year period of monetary easing, which saw the Federal
Reserve Bank ("Fed") steer the key federal funds target rate /i/ down to a
four-decade low of 1%, the Fed reversed course in late June to what many
observers believe will be a protracted period of monetary tightening, or
steering short-term interest rates higher. Higher interest rates can act as a
brake on robust economic growth, helping maintain a balance between steady
growth and the inflation that generally accompanies that growth.

The Fed's increase in the federal funds rate, to 1.25% at the end of June, was
widely anticipated. As bond prices declined, the yields on most fixed-income
instruments, particularly those on longer-maturity issues, began moving up
earlier this year and continued their ascent as it became more evident that the
improving economy and higher inflation would compel the Fed to act in June. In
particular, evidence of renewed job growth - the one missing piece from the
economic recovery - drove rates higher beginning in the spring.
Intermediate-term municipal bonds, particularly those of 7- to 10-year
maturities, succumbed to more pricing pressure than 15- to 20-year issues and
short-term notes, but all these maturity classes held up better than bonds with
longer maturities of more than 22 years. /ii/

Market Overview

During the six months ended June 30, 2004, the Salomon Brothers Municipal
Partners Fund Inc. returned -3.38% based on its New York Stock Exchange ("NYSE")
market price and -1.39% based on its net asset value ("NAV") /iii/ per share.The
fund's benchmark, the unmanaged Lehman Brothers Municipal Bond Index /iv/
returned -0.68 and its Lipper general municipal debt (leveraged) closed-end
funds category average returned -1.26% over the same time frame. /v/ Please note
that Lipper performance returns are based on each fund's NAV. The average credit
rating of holdings in the fund was Aa1 (or deemed by the portfolio manager to be
of comparable credit quality). /vi/ The fund had the largest exposure to the
water-and-sewer, healthcare and transportation sectors. The fund's largest
aggregated holdings by state were New Jersey, Illinois and Ohio.

During this six-month period, the fund distributed dividends to shareholders
totaling $0.42 per share. The performance table on the following page, 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 June 30, 2004. PAST
PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. The fund's yields will vary.

Certain investors may be subject to the federal Alternative Minimum Tax, and
state and local taxes may apply. Capital gains, if any, are fully taxable.

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 "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.
The annualized distribution yield assumes a current monthly income dividend rate
of $0.070 for 12 months. These yields are as of June 30, 2004 and are subject to
change.

Information About Your Fund

In recent months several issues in the mutual fund industry have come under the
scrutiny of federal and state regulators. The fund's Adviser and some of its
affiliates have received requests for information from various government
regulators regarding market timing, late trading, fees and other mutual fund
issues in connection with various investigations. The fund has been informed
that the Adviser and its affiliates are responding to those information
requests, but are not in a position to predict the outcome of these requests and
investigations.

In November 2003, Citigroup Asset Management disclosed an investigation by the
Securities and Exchange Commission ("SEC") and the U.S. Attorney relating to
Citigroup Asset Management's entry into the transfer agency business during
1997-1999. On July 20, 2004, Citigroup disclosed that it had been notified by
the Staff of the SEC that the Staff is considering recommending a civil
injunctive action and/or an administrative proceeding against certain advisory
and transfer agent entities affiliated with Citigroup relating to the creation
and operation of its internal transfer agent unit to serve primarily the Smith
Barney family of mutual funds. This internal transfer agent did not provide
services to the fund. Citigroup is cooperating with the SEC and will seek to
resolve this matter in discussion with the SEC Staff. Although there can be no
assurance, Citigroup does not believe that this matter will have a material
adverse effect on the fund.

RISKS: Investors could lose money on their investment in the fund. Certain
investors may be subject to the Federal Alternative Minimum Tax (AMT), and state
and local taxes will 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.

i   The federal funds rate is the interest rate that banks with excess reserves
    at a Federal Reserve district bank charges other banks that need overnight
    loans.

ii  Source: Based upon Lehman Brothers index performance data for each
    respective maturity category of municipal bonds.

iii NAV is a price that reflects the value of the fund's underlying portfolio
    plus other assets, less the fund's liabilities. However, the price at which
    an investor may buy or sell shares of the fund is at the fund's market
    price as determined by supply of and demand for the fund's common shares,
    which may be more or less than the fund's NAV.

iv  The Lehman Brothers Municipal Bond Index is a broad measure of the
    municipal bond market with maturities of at least one year.

v   Lipper, Inc. is a major independent mutual-fund tracking organization.
    Returns are based on the six-month period ended June 30, 2004, calculated
    among the 65 funds in the fund's Lipper category including the reinvestment
    of dividends and capital gains, if any.

vi  Bonds rated "Aa" are judged to be of high quality by all standards by
    Moody's Investors Service. 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 as in "Aaa"
    securities or fluctuations 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. Numerical modifiers
    1, 2 and 3 may be applied to each generic rating from "Aa" to "B", where 1
    is the highest and 3 is the lower rating within its generic category.

Long-Term Security Ratings (unaudited)

Standard & Poor's Ratings Service ("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. 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 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 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, they face 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 Investors Service ("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.

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 as 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 Moody's or Standard & Poor's
         as indicated.

                                                                          PAGE 9

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.

SALOMON BROTHERS MUNICIPAL PARTNERS FUND INC.

Notes to Financial Statements (unaudited)


Note 1. Organization and Significant Accounting Policies

Salomon Brothers Municipal Partners Fund Inc. ("Fund"), was incorporated in
Maryland on November 24, 1992 and is registered as a diversified, closed-end
management investment company under the Investment Company Act of 1940, as
amended. The Board of Directors authorized 100 million shares of $0.001 par
value common stock. The Fund's primary investment objective is to seek a high
level of current income which is exempt from federal income taxes, consistent
with the preservation of capital. As a secondary investment objective, the Fund
intends to enhance portfolio value by purchasing tax exempt securities that, in
the opinion of Salomon Brothers Asset Management Inc ("SBAM"), an indirect
wholly-owned subsidiary of Citigroup Inc. ("Citigroup"), may appreciate in value
relative to other similar obligations in the marketplace.

The following are a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
policies are in conformity with U.S. generally accepted accounting principles
("GAAP"), which requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
amounts could differ from those estimates.

SECURITIES VALUATION. Tax-exempt securities are valued by independent pricing
services which use prices provided by market-makers or estimates of market
values obtained from yield data relating to instruments or securities with
similar characteristics. Short-term investments having a maturity of 60 days or
less are valued at amortized cost which approximates market value. Securities
for which reliable quotations are not readily available are valued at fair value
as determined in good faith by, or under procedures established by, the Board of
Directors.

INVESTMENT TRANSACTIONS AND INVESTMENT INCOME. Securities transactions are
recorded on the trade date. Realized gains and losses on sales of securities are
calculated on the identified cost basis. Interest income is accrued on a daily
basis. The Fund amortizes premiums and accretes discounts on securities
purchased using the effective interest method.

FEDERAL INCOME TAXES. The Fund has complied and intends to continue to comply
with the requirements of the Internal Revenue Code of 1986, as amended,
applicable to regulated investment companies, and to distribute substantially
all of its income and capital gains, if any, to its shareholders. Therefore, no
federal income tax or excise tax provision is required. The character of income
and gains to be distributed are determined in accordance with income tax
regulations which may differ from GAAP.

PAGE 14



SALOMON BROTHERS MUNICIPAL PARTNERS FUND INC.


Notes to Financial Statements (unaudited) (continued)


DIVIDENDS AND DISTRIBUTIONS. The Fund declares and pays dividends and
distributions to common shareholders monthly from net investment income, net
realized short-term capital gains and other sources, if necessary. Long-term
capital gains, if any, in excess of loss carryovers are expected to be
distributed annually. Dividends and distributions to common shareholders are
recorded on the ex-dividend date. Dividends and distributions to preferred
shareholders are accrued on a weekly basis and are determined as described in
Note 4. The amount of dividends and distributions from net investment income and
net realized gains are determined in accordance with federal income tax
regulations, which may differ from GAAP.

Note 2. Management and Advisory Fees and Other Transactions

SBAM acts as the investment adviser and administrator of the Fund. SBAM provides
all management, advisory and administration services for the Fund. As
compensation for its services, the Fund pays SBAM an investment management fee
at an annual rate of 0.55% of the Fund's average weekly net assets. For purposes
of calculating this fee, the liquidation value of any outstanding preferred
stock of the Fund is not deducted in determining the Fund's average weekly net
assets. This fee is calculated daily and paid monthly.

SBAM has delegated certain administrative services to Smith Barney Fund
Management LLC ("SBFM"), another indirect wholly-owned subsidiary of Citigroup,
pursuant to a Sub-Administration Agreement between SBAM and SBFM.

Note 3. Investments

For the six months ended June 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.......................................................... $14,379,322
                                                                    ===========
Sales.............................................................. $15,672,685
                                                                    ===========

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

Gross unrealized appreciation...................................... $ 5,181,726
Gross unrealized depreciation......................................    (791,330)
                                                                    -----------
Net unrealized appreciation........................................ $ 4,390,396
                                                                    ===========


                                                                         PAGE 15

Note 4. Auction Rate Preferred Stock

On April 2, 1993, the Fund closed its public offering of 800 shares of $0.001
par value Auction Rate Preferred Stock ("Preferred Stock") at an offering price
of $50,000 per share. The Preferred Stock has a liquidation preference of
$50,000 per share plus an amount equal to accumulated but unpaid dividends
(whether or not earned or declared) and subject to certain restrictions, are
redeemable in whole or in part.

Dividend rates generally reset every 7 days and are determined by auction
procedures. The dividend rates on the Preferred Stock during the six months
ended June 30, 2004 ranged from 0.860% to 1.400%. The weighted average dividend
rate for the six months ended June 30, 2004 was 1.076%.

The Fund is subject to certain restrictions relating to the Preferred Stock. The
Fund may not declare dividends or make other distributions on shares of common
stock or purchase any such shares if, at the time of the declaration,
distribution or purchase, asset coverage with respect to the outstanding
Preferred Stock would be less than 200%. The Preferred Stock is also subject to
mandatory redemption at $50,000 per share plus any accumulated or unpaid
dividends, whether or not declared, if certain requirements relating to the
composition of the assets and liabilities of the Fund as set forth in its
Articles Supplementary are not satisfied.

The Preferred Stock, which are entitled to one vote per share, generally vote
with the common shares but vote separately as a class to elect two directors and
on certain matters affecting the rights of the Preferred Stock.

The issuance of preferred stock poses certain risks to holders of common stock,
including, among others the possibility of greater market price volatility and
in certain market conditions, the yield to holders of common stock may be
adversely affected.

The Fund is required to maintain certain asset coverages with respect to the
Preferred Stock. If the Fund fails to maintain these coverages and does not cure
any such failure within the required time period, the Fund is required to redeem
a requisite number of the Preferred Stock in order to meet the applicable
requirement. Additionally, failure to meet the foregoing asset requirements
would restrict the Fund's ability to pay dividends to common shareholders.

Note 5. Concentration of Credit Risk

Since the Fund invests a portion of its assets in issuers located in a single
state, it may be affected by economic and political developments in a specific
state or region. Certain debt obligations held by the Fund are entitled to the
benefit of insurance, standby letters of credit or other guarantees of banks or
other financial institutions.

Note 6. Events Subsequent to June 30, 2004

COMMON STOCK DIVIDENDS. On May 14, 2004, the Board of Directors of the Fund
declared two common share dividends from net investment income, each in the
amount of $0.070 per share, payable on July 30 and August 27, 2004 to
shareholders of record on July 13 and August 17, 2004, respectively. In
addition, on July 29, 2004, the Board of Directors of the Fund declared three
common share dividends from net investment income, each in the amount of $0.070
per share, payable on September 24, October 29, and November 26, 2004 to
shareholders of record on September 14, October 13 and November 16, 2004,
respectively.

PREFERRED STOCK DIVIDENDS. The Board of Directors designated each of the
following dividend periods as a Special Rate Period. With each auction date, the
regular auction procedure resumes, subject to the Fund's ability to designate
any subsequent dividend period as a Special Rate Period.

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

Note 7.  Additional Information

Citigroup has been notified by the Staff of the Securities and Exchange
Commission ("SEC") that the Staff is considering recommending a civil injunctive
action and/or an administrative proceeding against Citigroup Asset Management
("CAM"), including its applicable investment advisory companies and Citicorp
Trust Bank ("CTB"), an internal transfer agent, relating to the creation and
operation of the internal transfer agent unit to serve certain CAM-managed
funds. CTB did not provide services to the Fund. This notification arises out of
a previously disclosed investigation by the SEC and the U.S. Attorney and
relates to CTB's entry in 1999 into the transfer agency business, CAM's
retention of, and agreements with an

                                                                         PAGE 17

unaffiliated sub-transfer agent, the adequacy of the disclosures made to the
fund boards that approved the transfer agency arrangements, (including CAM's
failure to disclose a related revenue guarantee agreement benefiting CAM and its
affiliates), and CAM's operation of and compensation for the transfer agency
business. The revenue guarantee described above was terminated in 1999 and CAM
will be paying the applicable funds, primarily through fee waivers, a total of
approximately $17 million (plus interest) that is the amount of the revenue
received by Citigroup relating to the revenue guarantee. The Fund did not
implement the contractual arrangement described above and therefore will not
receive any portion of the payment. Citigroup is cooperating fully in the
investigation and will seek to resolve the matter in discussions with the SEC
Staff. Although there can be no assurance, Citigroup does not believe that this
matter will have a material adverse effect on the Fund.

Dividend Reinvestment Plan (unaudited)

Pursuant to certain rules of the Securities and Exchange Commission, the
following additional disclosure is provided.

Pursuant to the Fund's Dividend Reinvestment Plan ("Plan"), holders of Common
Stock whose shares of Common Stock are registered in their own names will be
deemed to have elected to have all distributions automatically reinvested by
EquiServe Trust Company, N.A. ("Plan Agent") in Fund shares pursuant to the
Plan, unless they elect to receive distributions in cash. Holders of Common
Stock who elect to receive distributions in cash will receive all distributions
in cash by check in dollars mailed directly to the holder by the Plan Agent as
dividend-paying agent. Holders of Common Stock who do not wish to have
distributions automatically reinvested should notify the Plan Agent at the
address below. Distributions with respect to Common Stock registered in the name
of a bank, broker-dealer or other nominee (i.e., in "street name") will be
reinvested under the Plan unless the service is not provided by the bank,
broker-dealer or other nominee or the holder elects to receive dividends and
distributions in cash. Investors who own shares registered in the name of a
bank, broker-dealer or other nominee should consult with such nominee as to
participation in the Plan through such nominee, and may be required to have
their shares registered in their own names in order to participate in the Plan.

The Plan Agent serves as agent for the holders of Common Stock in administering
the Plan. After the Fund declares a dividend on the Common Stock or determines
to make a capital gain distribution, the Plan Agent will, as agent for the
participants, receive the cash payment and use it to buy the Fund's Common Stock
in the open market, on the New YorkStock Exchange or elsewhere, for the
participants' accounts. The Fund will not issue any new shares of Common Stock
in connection with the Plan.

Participants have the option of making additional cash payments to the Plan
Agent, monthly, in a minimum amount of $250, for investment in the Fund's Common
Stock. The Plan Agent will use all such funds received from participants to
purchase shares of Common Stock in the open market on or about the first
business day of each month. To avoid unnecessary cash accumulations, and also to
allow ample time for receipt and processing by the Plan Agent, it is suggested
that participants send in voluntary cash payments to be received by the Plan
Agent approximately ten days before an applicable purchase date specified above.
A participant may withdraw a voluntary cash payment by written notice, if the
notice is received by the Plan Agent not less than 48 hours before such payment
is to be invested.

The Plan Agent maintains all shareholder accounts in the Plan and furnishes
written confirmations of all transactions in an account, including information
needed by shareholders for personal and tax records. Shares of Common Stock in
the account of each Plan participant will be held by the Plan Agent in the name
of the participant, and each shareholder's proxy will include those shares
purchased pursuant to the Plan.

In the case of holders of Common Stock, such as banks, broker-dealers or other
nominees, who hold shares for others who are beneficial owners, the Plan Agent
will administer the Plan on the basis of the number of shares of Common Stock
certified from time to time by the holders as representing the total amount
registered in such holders' names and held for the account of beneficial owners
that have not elected to receive distributions in cash.


                                                                         PAGE 21




SALOMON BROTHERS MUNICIPAL PARTNERS FUND INC.


Dividend Reinvestment Plan (unaudited) (continued)

There is no charge to participants for reinvesting dividends or capital gains
distributions or voluntary cash payments. The Plan Agent's fees for the
reinvestment of dividends and capital gains distributions and voluntary cash
payments will be paid by the Fund. However, each participant will pay a pro rata
share of brokerage commissions incurred with respect to the Plan Agent's open
market purchases in connection with the reinvestment of dividends and
distributions and voluntary cash payments made by the participant. The receipt
of dividends and distributions under the Plan will not relieve participants of
any income tax which may be payable on such dividends or distributions.

Participants may terminate their accounts under the Plan by notifying the Plan
Agent in writing. Such termination will be effective immediately if notice in
writing is received by the Plan Agent not less than ten days prior to any
dividend or distribution record date. Upon termination, the Plan Agent will send
the participant a certificate for the full shares held in the account and a cash
adjustment for any fractional shares or, upon written instruction from the
participant, the Plan Agent will sell part or all of the participant's shares
and remit the proceeds to the participant, less a $2.50 fee plus brokerage
commission for the transaction.

Experience under the Plan may indicate that changes in the Plan are desirable.
Accordingly, the Fund and the Plan Agent reserve the right to terminate the Plan
as applied to any voluntary cash payments made and any dividend or distribution
paid subsequent to notice of the termination sent to all participants in the
Plan at least 30 days before the record date for the dividend or distribution.
The Plan also may be amended by the Fund or the Plan Agent upon at least 30
days' written notice to participants in the Plan.

All correspondence concerning the Plan should be directed tothe Plan Agent, P.O.
Box 43010, Providence, Rhode Island 02940-3010.

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.
