July 15, 2003

Dear Shareholder,

We present you with the annual report for Managed High Yield Plus Fund Inc. for
the fiscal year ended May 31, 2003.

An Interview with Portfolio Manager Marianne Rossi

Q.    Can you summarize how the Fund performed during the review period?

A.    During the fiscal year ended May 31, 2003, the Fund pro-duced a net asset
      value return of 10.92%. The Fund's performance was in line with the 10.98%
      average return (on a net asset value basis) of its peers, the Lipper High
      Current Yield Funds (Leveraged) Median. However, on a market price basis,
      the Fund's 3.85% return significantly underperformed the 10.54% return of
      its peer group. (For more on the Fund's performance, including market
      price returns, please refer to "Performance At A Glance" on page 6.)

      The Fund used leverage during the period, which as of May 31, 2003 was
      27.8%. Leverage magnifies returns on the upside and on the downside, and
      can create wider dispersions of returns within the Fund's peer group.

Q.    Can you describe the economic environment during the reporting period?

A.    Other than a brief revival during the third quarter of 2002, the US
      economy was generally weak during the Fund's fiscal year. The Gross
      Domestic Product (GDP) figure posted in the second quarter of 2002 was an
      anemic 1.7%, as threats of terrorism, turmoil in the Middle East, tepid
      corporate spending, a weak stock market and corporate accounting scandals
      all took their toll. The news improved somewhat during the third quarter,
      as GDP rose to 4.0%.

      However, over the last three months of 2002 and into the first three
      months of 2003, GDP figures came in at 1.4% and 1.9%, respectively,
      reflecting the economy's underlying weakness.

Q.    What were some of the reasons for the tepid economic growth?

A.    Throughout 2002, consumer spending, which accounts for two-thirds of the
      US economy, was relatively strong. This contrasted sharply with corporate
      spending, which remained subdued as many companies postponed major
      purchases until they saw clearer signs of a sustainable economic recovery.
      However, both consumer and corporate spending weakened in early 2003 as
      the looming--and then eventual--war in Iraq, problems in North Korea and
      heightened concerns about terrorism preoccupied the country. In the war's
      wake, the signals relating to consumer and business spending have been
      mixed.

Q.    How did the Federal Reserve Board (the "Fed") react to the weak economy?

A.    During the first five months of the reporting period, the Fed kept rates
      steady. Then, in November 2002, the Fed took action to guard against a
      "double-dip" recession. Acknowledging that the economy had hit a "soft
      spot," the Fed lowered the federal funds rate one half of a percentage
      point to 1.25%--a 41-year low.

      In the ensuing months, the Fed deferred from making any additional rate
      cuts. It indicated, however, at its March 19, 2003 meeting, that it was
      assuming a "heightened surveillance" of the economy in light of the war in
      Iraq, and, in subsequent meetings, that it was leaving the door open for
      another rate cut. The much-anticipated rate cut finally came at the Fed
      meeting on June 25, after period end. The Fed cut the fed funds rate by a
      quarter of a percentage point to 1%--its lowest level since 1958. The
      regulatory body cited the fact that the economy had yet to exhibit
      sustainable growth, and that "a slightly more expansive monetary policy
      would add further support for an economy which it expects to improve over
      time."

Q.    How did high yield bonds perform during the Fund's fiscal year?

A.    During the first five months of the reporting period, the high yield
      market performed poorly. The weak economy, numerous accounting scandals,
      plunging equity markets and an investor "flight to quality" contributed to
      historically high spreads for corporate bonds. Additionally, high yield
      default rates topped 10%, and demand for these securities was tepid, at
      best. However, in October


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

Managed High Yield Plus Fund Inc.

      2002, spreads peaked, and the high yield market has performed very well
      since that time.

      The primary turning point came when third quarter 2002 corporate earnings
      did not surprise on the downside. Other factors that exerted a positive
      influence on the sector included falling default rates, a slowing in the
      pace of bond rating downgrades versus upgrades, and more willingness by
      banks to work with companies to secure credit. The demand for high yield
      bonds surged, providing companies with an added source of capital.
      Furthermore, mutual funds, pension plans and insurance companies began to
      turn to these securities to generate incremental yield in the low interest
      rate environment.

Q.    What strategies enhanced the Fund's performance during the reporting
      period?

A.    The Fund's sector and security selection boosted relative results during
      the first half of the period. In particular, the Fund's weighting to
      gaming, broadcasting and healthcare helped performance, and led the Fund
      to outperform its benchmark Lipper peer group during this time.

      Looking at the reporting period as a whole, the Fund's exposure to
      CCC-rated bonds enhanced returns. The Fund also maintained an overweight
      to the wireless telecommunications sector that added to performance. Also,
      cable performed well during the second half of the reporting period,
      rebounding from earlier low levels.

Q.    What strategies did not meet your expectations?

A.    The Fund's underperformance during the second half of the reporting period
      was due to the underweighting of several sectors and securities that were
      deeply distressed. In particular, the Fund's underweight to the utilities
      sector negatively impacted performance. Also two energy companies,
      Williams and El Paso, rallied substantially once the companies raised
      desperately needed liquidity.

Managed High Yield Plus Fund Inc.

Q.    Were there any adjustments to the Fund's portfolio, in terms of credit
      quality or sector allocation?

A.    We increased exposure to the chemical and paper and forest products
      sectors, in anticipation of a better economic outlook and due to
      attractive valuations. We decreased exposure to the broadcasting and
      gaming industries, as these sectors have performed well and we sought to
      lock in gains.

Q.    What is your outlook for the economy and the high yield market?

A.    While there have been mixed signals regarding the strength of the economy,
      we are cautiously optimistic about the economic outlook. We are encouraged
      to see that companies in general are reporting operating results that are
      in line with, or slightly better than, expectations. Banks are also being
      more accommodative in terms of their lending policies. The market has
      increased substantially, and we could see investors lock in gains. While
      this may lead to periods of volatility in the short term, we're encouraged
      by the high yield market's fundamentals over the longer term. More
      companies are gaining access to capital, and the trend toward lower
      default levels should continue. We also expect to see fewer downgrades
      versus upgrades going forward.

Q.    How do you foresee positioning the Fund given your outlook?

A.    As always, we believe that security selection will be critical to the
      success of the Fund. Overall, we feel the Fund is currently
      well-positioned given the current economic and market environment. We're
      also selectively increasing the Fund's exposure to the utility sector,
      focusing on firms that we believe offer solid opportunities over the long
      term.

*     Since inception returns for the Fund are calculated from the date of the
      Fund's inception on June 26, 1998. Since inception returns for the Lipper
      High Current Yield Funds (Leveraged) Median are calculated from the month
      end closest to the Fund's inception: June 30, 1998.

**    Past performance is no guarantee of future results. The Fund's share price
      and investment return will vary so that an investor's shares, when sold,
      may be worth more or less than their original cost. NAV and market price
      returns for periods of one year or less are cumulative. NAV return
      assumes, for illustration only, that dividends were reinvested at the net
      asset value on the payable dates. Returns do not reflect any commissions
      and are not representative of the performance of an individual investment.
      Returns do not reflect the deduction of taxes that a shareholder would pay
      on Fund distributions. Generally, total investment return based on net
      asset value will be higher than total investment return based on market
      price in periods where there is an increase in the discount or a decrease
      in the premium of the market price to the net asset value from the
      beginning to the end of such periods. Conversely, total investment return
      based on net asset value will be lower than total investment return based
      on market value in years where there is a decrease in the discount or an
      increase in the premium of the market value to the net asset value from
      the beginning to the end of such periods.

Managed High Yield Plus Fund Inc.

Notes to Financial Statements

Organization and Significant Accounting Policies

Managed High Yield Plus Fund Inc. (the "Fund") was incorporated in Maryland on
April 24, 1998, and is registered with the Securities and Exchange Commission
under the Investment Company Act of 1940, as amended, as a closed-end
diversified management investment company. The Fund's primary investment
objective is to seek high income. Its secondary objective is to seek capital
appreciation.

The preparation of financial statements in accordance with accounting principles
generally accepted in the United States requires the Fund's management to make
estimates and assumptions that affect the reported amounts and disclosures in
the financial statements. Actual results could differ from those estimates. The
following is a summary of significant accounting policies:

Valuation of Investments--The Fund calculates its net asset value based on the
current market value, where available, for its portfolio securities. The Fund
normally obtains market values for its securities from independent pricing
sources and broker-dealers. Independent pricing sources may use reported last
sale prices, current market quotations or valuations from computerized "matrix"
systems that derive values based on comparable securities. A matrix system
incorporates parameters such as security quality, maturity and coupon, and/or
research and evaluations by its staff, including review of broker-dealer market
price quotations, if available, in determining the valuation of the portfolio
securities. Securities traded in the over-the-counter ("OTC") market and listed
on The Nasdaq Stock Market, Inc. ("Nasdaq") normally are valued at the NASDAQ
Official Closing Price. Other OTC securities are valued at the last bid price
available on the valuation date prior to valuation. Securities which are listed
on U.S. and foreign stock exchanges normally are valued at the last sale price
on the day the securities are valued or, lacking any sales on such day, at the
last available bid price. In cases where securities are traded on more than one
exchange, the securities are valued on the exchange designated as the primary
market by UBS Global Asset Management (US) Inc. ("UBS Global AM"), the
investment manager and administrator of the Fund or by the Fund's investment
sub-advisor. UBS Global AM is an indirect wholly owned asset management
subsidiary of UBS AG, an internationally diversified organization with
headquarters in Zurich, Switzerland and operations in many areas of the
financial services industry. If a market value is not available from an
independent pricing source for a particular security, that security is valued at
fair value as determined in good faith by a management committee under the
direction of the Fund's board of directors (the "Board"). The amortized cost
method of valuation, which approximates market value, generally is used to value
short-term debt instruments with sixty days or less remaining to maturity,
unless the Fund's Board determines that this does not represent fair value. All
investments quoted in foreign currencies will be valued daily in U.S. dollars on
the basis


- --------------------------------------------------------------------------------
                                                                              21

Notes to Financial Statements

of the foreign currency exchange rates prevailing at the time such valuation is
determined by the Fund's custodian.

Repurchase Agreements--The Fund may purchase securities or other obligations
from a bank or securities dealer (or its affiliates), subject to the seller's
agreement to repurchase them at an agreed upon date (or upon demand) and price.
The Fund maintains custody of the underlying obligations prior to their
repurchase, either through its regular custodian or through a special
"tri-party" custodian or sub-custodian that maintains a separate account for
both the Fund and its counterparty. The underlying collateral is valued daily on
a mark-to-market basis to ensure that the value, including accrued interest, is
at least equal to the repurchase price. In the event of default of the
obligation to repurchase, the Fund has the right to liquidate the collateral and
apply the proceeds in satisfaction of the obligation. Repurchase agreements
involving obligations other than U.S. government securities (such as commercial
paper, corporate bonds and mortgage loans) may be subject to special risks and
may not have the benefit of certain protections in the event of the
counterparty's insolvency. If the seller (or seller's guarantor, if any) becomes
insolvent, the Fund may suffer delays, costs and possible losses in connection
with the disposition or retention of the collateral. Under certain
circumstances, in the event of default or bankruptcy by the other party to the
agreement, realization and/or retention of the collateral may be subject to
legal proceedings. The Fund occasionally participates in joint repurchase
agreement transactions with other funds managed, advised or sub-advised by UBS
Global AM.

Investment Transactions and Investment Income--Investment transactions are
recorded on the trade date. Realized gains and losses from investment
transactions are calculated using the identified cost method. Interest income is
recorded on an accrual basis. Discounts are accreted and premiums are amortized
as adjustments to interest income and the identified cost of investments.

Dividends and Distributions--Dividends and distributions to shareholders are
recorded on the ex-dividend date. The amount of dividends from net investment
income and distributions from net realized capital gains is determined in
accordance with U.S. federal income tax regulations, which may differ from
accounting principles generally accepted in the United States. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification.

Notes to Financial Statements

Borrowings

The Fund has a $150 million committed credit facility (the "Facility"). Under
the terms of the Facility, the Fund borrows at the London Interbank Overnight
Rate ("LIBOR") plus facility and administrative fees. In addition, the Fund pays
a liquidity fee on the entire amount of the Facility. The Fund may borrow up to
331/3% of its total assets up to the committed amount. In accordance with the
terms of the Facility, the Fund has pledged assets in the amount of $215,107,304
on May 31, 2003 as collateral for the bank loan.

For the year ended May 31, 2003, the Fund borrowed a daily average balance of
$80,607,534 at a weighted average interest rate of approximately 2.18%.

Concentration of Risk

The ability of the issuers of the debt securities held by the Fund to meet their
obligations may be affected by economic developments, including those particular
to a specific industry, country or region. In addition, the Fund's use of
leverage creates greater volatility in the Fund's net asset value and market
price of its shares.

Investment Manager and Administrator, Sub-Advisor

The Board has approved an investment management and administration contract
("Management Contract") with UBS Global AM, under which UBS Global AM serves as
investment manager and administrator of the Fund. In accordance with the
Management Contract, the Fund pays UBS Global AM an investment management and
administration fee, which is accrued weekly and paid monthly, at the annual rate
of 0.70% of the Fund's average weekly total assets minus liabilities other than
the aggregate indebtedness constituting leverage.

UBS Global AM has entered into a sub-advisory contract ("Sub-Advisory Contract")
with UBS Global Asset Management (New York) Inc. pursuant to which UBS Global
Asset Management (New York) Inc. serves as investment sub-advisor for the Fund.
Under the Sub-Advisory Contract, UBS Global AM (not the Fund) is obligated to
pay UBS Global Asset Management (New York) Inc. a fee, computed weekly and paid
monthly, at the annual rate of 0.2375% of the Fund's average weekly total assets
minus liabilities other than the aggregate indebtedness constituting leverage.

For the year ended May 31, 2003, aggregate purchases and sales of portfolio
securities, excluding short-term securities, were $93,869,798 and $105,598,739,
respectively.

The Fund intends to distribute substantially all of its taxable income and to
comply with the other requirements of the Internal Revenue Code applicable to
regulated investment companies. Accordingly, no provision for federal income
taxes is required. In addition, by distributing during each calendar year
substantially all of its net investment income, realized capital gains and
certain other amounts, if any, the Fund intends not to be subject to federal

Managed High Yield Plus Fund Inc.

Notes to Financial Statements

The difference between book-basis and tax-basis net unrealized depreciation of
investments is attributable to the tax deferral of losses on wash sales.

At May 31, 2003, the Fund had a net capital loss carryforward of $303,756,768.
This loss carryforward is available as a reduction, to the extent provided in
the regulations, of future net realized capital gains, and will expire as
follows: $531,918 in 2004; $1,037,133 in 2005; $13,100,516 in 2007; $50,099,935
in 2008; $71,221,921 in 2009; $71,854,329 in 2010; and $95,911,016 in 2011. The
capital loss carryforward includes $17,067,955 of capital losses from the
acquisition of Managed High Yield Fund Inc. on June 2, 2000. These losses may
be subject to annual limitations pursuant to section 382(b)(1) of the Internal
Revenue Code. To the extent that such losses are used to offset future net
realized capital gains, it is probable these gains will not be distributed.
Also, in accordance with U.S. Treasury regulations, the Fund has elected to
defer $21,871,615 of net realized capital losses arising after October 31,
2002. Such losses are treated for tax purposes as arising on June 1, 2003.

To reflect reclassifications arising from permanent "book/tax" differences for
the year ended May 31, 2003, distributions in excess of net investment income
was decreased by $692, accumulated net realized loss from investment
transactions was increased by $17,067,955 and capital stock was increased by
$17,067,263.

confirmation of investments owned as of May 31, 2003, by correspondence with the
custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our

secondary objective is to seek capital appreciation. The Fund's investment
manager and administrator is UBS Global Asset Management (US) Inc. ("UBS Global
AM"), an indirect wholly-owned asset management subsidiary of UBS AG, which had
over $72.1 billion in assets under management as of June 30, 2003. UBS Global AM

online on the Fund's Web site www.ubs.com/ubsglobalam-proxy, or on the EDGAR
Database on the SEC's Web site (http://www.sec.gov).

Shareholder Information

The Fund's NYSE trading symbol is "HYF." Comparative net asset value and market
price information about the Fund is published weekly in The Wall Street Journal,
The New York Times and Barron's, as well as in numerous other publications.

Dividend Reinvestment Plan

The Fund's Board has established a Dividend Reinvestment Plan (the "Plan") under
which all shareholders whose shares are registered in their own names, or in the
name of UBS Financial Services Inc., or its nominee, will have all dividends and
other distributions on their shares automatically reinvested in additional
shares, unless such shareholders elect to receive cash. Shareholders who elect
to hold their shares in the name of another broker or nominee should contact
such broker or nominee to determine whether, or how, they may participate in the
Plan. The ability of such shareholders to participate in the Plan may change if
their shares are transferred into the name of another broker or nominee.

A shareholder may elect not to participate in the Plan or may terminate
participation in the Plan at any time without penalty, and shareholders who have
previously terminated participation in the Plan may rejoin it at any time.
Changes in elections must be made in writing to the Fund's transfer agent and
should include the shareholder's name and address as they appear on that share
certificate or in the transfer agent's records. An election to terminate
participation in the Plan, until such election is changed, will be deemed an
election by a shareholder to

Managed High Yield Plus Fund Inc.

take all subsequent distributions in cash. An election will be effective only
for distributions declared and having a record date at least ten days after the
date on which the election is received.

The transfer agent will serve as agent for the shareholders in administering the
Plan. After the Fund declares a dividend or determines to make any other
distribution, the transfer agent, as agent for the participants, receives the
cash payment. Whenever the Fund declares an income dividend or a capital gain
distribution (collectively referred to in this section as "dividends") payable
either in shares or in cash, non-participants in the Plan will receive cash and
participants in the Plan will receive the equivalent in shares. The transfer
agent will acquire shares for the participants' accounts, depending upon the
circumstances described below, either (i) through receipt of unissued but
authorized shares from the Fund ("newly issued shares") or (ii) by purchase of
outstanding shares on the open market, on the NYSE or elsewhere ("open-market
purchases"). If, on the dividend payment date, the net asset value per share is
equal to or less than the market price per share, plus estimated brokerage
commissions (such condition being referred to herein as "market premium"), the
transfer agent will invest the dividend amount in newly issued shares on behalf
of the participants. The number of newly issued shares to be credited to each
participant's account will be determined by dividing the dollar amount of the
dividend by the net asset value per share (but in no event less than 95% of the
then current market price per share) on the date the shares were issued. If, on
the dividend payment date, the net asset value per share is greater than the
market value per share, plus estimated brokerage commissions (such condition
being referred to herein as "market discount"), the transfer agent will invest
the dividend amount in shares acquired on behalf of the participants in
open-market purchases. The number of outstanding shares purchased with each
distribution for a particular shareholder equals the result obtained by dividing
the amount of the distribution payable to that shareholder by the average price
per share (including applicable brokerage commissions) that the transfer agent
was able to obtain in the open market.

In the event of a market discount on the dividend payment date, the transfer
agent will have until the last business day before the next date on which the
shares trade on an "ex-dividend" basis, but in no event more than 30 days after
the dividend payment date (the "last purchase date"), to invest the dividend
amount in shares acquired in open-market purchases. It is contemplated that the
Fund will pay monthly income dividends. Therefore, the period during which
open-market purchases can be made will exist only from the payment date of the
dividend through the date before the next "ex-dividend" date, which typically
will be approximately ten days. If, before the transfer agent has completed its
open-market purchases, the market price of a share, plus estimated brokerage
commis-

                                                                              29

sions, exceeds the net asset value per share, the average per share purchase
price paid by the transfer agent may exceed the Fund's net asset value per
share, resulting in the acquisition of fewer shares than if the dividend had
been paid in newly issued shares on the dividend payment date. Because of the
foregoing difficulty with respect to open-market purchases, the Plan provides
that, if the transfer agent is unable to invest the full dividend amount in
open-market purchases during the purchase period or if the market discount
shifts to a market premium during the purchase period, the transfer agent will
cease making open-market purchases and will invest the uninvested portion of the
dividend amount in newly issued shares at the close of business on the earlier
of the last purchase date or the first day during the purchase period on which
the net asset value per share equals or is less than the market price per share,
plus estimated brokerage commissions. The transfer agent will maintain all
shareholder accounts in the Plan and will furnish written confirmations of all
transactions in the accounts, including information needed by shareholders for
personal and tax records. Shares in the account of each Plan participant will be
held by the transfer agent in non-certificated form in the name of the
participant, and each shareholder's proxy will include those shares purchased
pursuant to the Plan. There will be no charge to participants for reinvesting
dividends. However, each participant will pay a pro rata share of brokerage
commissions incurred with respect to the transfer agent's open market purchases
of shares in connection with the reinvestment of dividends. The automatic
reinvestment of dividends in shares does not relieve participants of any income
tax that may be payable on such dividends.

Shareholders who participate in the Plan may receive benefits not available to
shareholders who do not participate in the Plan. If the market price (plus
commissions) of the shares is above their net asset value, participants in the
Plan will receive shares at less than they could otherwise purchase them and
will have shares with a cash value greater than the value of any cash dividends
they would have received on their shares. If the market price plus commissions
is below the net asset value, participants will receive dividends in shares with
a net asset value greater than the value of any cash dividends they would have
received on their shares. However, there may be insufficient shares available in
the market to distribute dividends in shares at prices below the net asset
value. Also, since the Fund does not redeem its shares, the price on resale may
be more or less than the net asset value.

Experience under the Plan may indicate that changes are desirable. Accordingly,
the Fund reserves the right to amend or terminate the Plan with respect to any
dividend or other distribution if notice of the change is sent to Plan
participants at least 30 days before the record date for such distribution. The
Plan also may be amended or terminated by the transfer agent by at least 30 days
written notice

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed - End
Management Investment Companies.

The registrant's Board of Directors believes that the voting of proxies on
securities held by the registrant is an important element of the overall
investment process. As such, the Board has delegated the responsibility to vote
such proxies to the registrant's sub-advisor. Following is a summary of the
proxy voting policy of the sub-advisor.

Corporate Governance Philosophy, Voting Guidelines and Policy Summary

The proxy voting policy of UBS Global Asset Management (New York) Inc. ("UBS
Global AM (New York)") is based on its belief that voting rights have economic
value and must be treated accordingly. Generally, UBS Global AM (New York)
expects the boards of directors of companies issuing securities held by its
clients to act as stewards of the financial assets of the company, to exercise
good judgment and practice diligent oversight with the management of the
company. While there is no absolute set of rules that determine appropriate
corporate governance under all circumstances and no set of rules will guarantee
ethical behavior, there are certain benchmarks, which, if substantial progress
is made toward, give evidence of good corporate governance. UBS Global AM (New
York) may delegate to an independent proxy voting and research service the
authority to exercise the voting rights associated with certain client holdings.
Any such delegation shall be made with the direction that the votes be exercised
in accordance with UBS Global AM (New York)'s proxy voting policy.

When UBS Global AM (New York)'s view of a company's management is favorable, UBS
Global AM (New York) generally supports current management initiatives. When UBS
Global AM (New York)'s view is that changes to the management structure would
probably increase shareholder value, UBS Global AM (New York) may not support
existing management proposals. In general, UBS Global AM (New York) (1) opposes
proposals which act to entrench management; (2) believes that boards should be
independent of company management and composed of persons with requisite skills,
knowledge and experience; (3) opposes structures which impose financial
constraints on changes in control; (4) believes remuneration should be
commensurate with responsibilities and performance; and (5) believes that
appropriate steps should be taken to ensure the independence of auditors.

UBS Global AM (New York) has implemented procedures designed to identify whether
it has a conflict of interests in voting a particular proxy proposal, which may
arise as a result of its or its affiliates' client relationships, marketing
efforts or banking, investment banking and broker/dealer activities. To address
such conflicts, UBS Global AM (New York) has imposed information barriers
between it and its affiliates who conduct banking, investment banking, and
broker/dealer activities and has implemented procedures to prevent business,
sales and marketing issues from influencing our proxy votes. Whenever UBS Global
AM (New York) is aware of a conflict with respect to a particular proxy, its
appropriate local corporate governance committee is required to review and agree
to the manner in which such proxy is voted.

Item 8. [Reserved by SEC for future use. ]

Item 9. Controls and Procedures.

      (a)   The registrant's principal executive officer and principal financial
            officer have concluded that the registrant's disclosure controls and
            procedures (as defined in Rule 30a-2(c) under the Investment Company
            Act of 1940) provide reasonable assurances that material information
            relating to the registrant is made known to them by the appropriate
            persons, based on

            their evaluation of these controls and procedures as of a date
            within 90 days of the filing date of this report.

      (b)   There were no significant changes in the registrant's internal
