Dear Shareholder,

   We are pleased to present you with the annual report for the PaineWebber
Strategic Income Fund ("the Fund") for the fiscal year ended November 30,
1998.


MARKET REVIEW
- --------------------------------------------------------------------------------

   "Flight to quality" remained the dominant theme in the bond markets during
the fiscal year ended November 30, 1998, as investors sought the safety and
liquidity of U.S. Treasury securities, especially short- to intermediate-term
debt.

   Turmoil hit the global capital markets in August when Russia devalued its
currency and effectively defaulted on its internal debt. The ensuing sell-off in
the global equity and emerging debt markets spurred the flight to U.S. Treasurys
to an even higher pitch. All sectors of the bond market suffered as risk
premiums soared. Emerging market debt fared the worst, with the high yield
sector following a distant second. U.S. corporate bonds were hard hit, and
corporations suffered from a market-induced credit crunch.

   The global sell-off continued to disrupt the financial markets in September.
Initial public offerings of stocks and the entire high-yield debt market ground
to a virtual halt. With market conditions so fragile, the Federal Reserve
lowered the Fed Funds rate (the rate for overnight loans) from 5.50% to 5.25%.
Barely two weeks into October, the Fed again lowered the Fed Funds rate and also
lowered the discount rate (the rate commercial banks pay to borrow from the
Federal Reserve). The market took this action as a sign of the Fed's resolve to
keep the economy growing in its effort to avoid a recession. Investors reacted
positively--the stock market rose and shorter-maturity Treasurys rallied.
Corporate bonds continued to lose ground as they lagged the rally in Treasury
yields.

   The Fed lowered both rates again in November, and several European central
banks followed suit in preparation for the January 1, 1999 debut of the euro
currency. The third rate reduction in as many months boosted corporate bonds and
mortgage-backed securities as market psychology and liquidity improved.


PORTFOLIO REVIEW
- --------------------------------------------------------------------------------

PERFORMANCE

   The Fund's total return consists of the change in net asset value with
dividends reinvested. For the fiscal year ended November 30, 1998, without
deducting sales charges, Class A shares gained 1.65%, Class B shares gained
0.87% and Class C shares gained 1.14%. Class Y shares commenced issuance on
February 17, 1998; from commencement through November 30, 1998, Class Y shares
lost 1.04%.

   The Fund's total return may be lower for shareowners who purchased or
redeemed Fund shares during the period. After deducting the maximum applicable
sales charges, Class A shares lost 2.41%, Class B shares lost 3.85% and Class C
shares gained 0.43%. Class Y shares are not subject to sales charges.

PAINEWEBBER STRATEGIC INCOME FUND                                 ANNUAL REPORT

                              PORTFOLIO HIGHLIGHTS

   The Fund allocates assets among three main sectors of the global bond
market--U.S. government/investment grade bonds, U.S. high-yield bonds and
non-U.S. bonds--and shifts emphasis among them as conditions warrant.

   Throughout the fiscal year, the Fund held positions consistent with our
long-term view that interest rates would continue to fall. The Fund began the
fiscal year with 47% of its portfolio in U.S. government and investment-grade
corporate bonds, 37% in high-yield bonds, 11% in foreign and emerging market
debt and 5% in cash. During the first half of the fiscal year these weightings
benefited the Fund as "flight-to-quality" buying drove up prices of U.S.
Treasurys and demand spread to the corporate and high-yield sectors.

   After the high-yield market weakened in April, we increased the Fund's
allocation to high-yield bonds in the belief that prices would rebound. Instead,
high-yield bonds suffered along with the rest of the bond market in the wake of
the Russian crisis. The Fund's high-yield and non-U.S. positions hurt returns.
From July to October, we gradually decreased exposure to high-yield bonds and
non-U.S. bonds while raising cash to defend the portfolio. As signs of recovery
appeared in November we reinvested in those sectors.

   High-Yield Sector--The Fund's overweighting in smaller U.S. issues hurt
performance as those issues lagged the overall high-yield market. Historically,
smaller issues (less than $200 million) generally have been less volatile than
larger issues. We think the higher volatility of smaller issues during the last
fiscal year may reflect a structural change in the market, with institutional
investors, who tend to buy larger issues, exerting greater influence. We have
begun redeploying assets into larger issues, and expect to continue this
redeployment going forward.

   U.S. Government and Investment Grade Sector--The Fund began the latter half
of its fiscal year overweighted in mortgage-backed and government agency
securities, as we maintained our focus on adding portfolio value by enhancing
yield. At the same time, we emphasized call protection in an environment of
heightened prepayment risk. We kept the Fund's exposure to the sector about the
same through the period.

   We believe mortgage spreads to Treasurys are extremely attractive despite
high prepayment risks. We think investors have become more credit-risk averse in
reaction to events in international markets, and we believe the high credit
quality of mortgage securities and their historically low prices will attract
investors to the sector.

   Global Sector--Our de-emphasis of non-U.S. exposure during the first half of
the fiscal year helped protect the Fund in the second half, though exposure to
anything besides U.S. Treasurys lowered returns. The Fund remained underweighted
in Europe, concentrating its holdings in the intermediate maturities of Germany,
Holland and the United Kingdom. Within the emerging markets allocation we
shifted exposure away from Latin America in favor of Europe and Asia.

OUTLOOK
- --------------------------------------------------------------------------------

   While the U.S. manufacturing sector has been losing jobs and industrial
production has been flat since Asia began unraveling in late 1997, the larger
economy has proven resilient. As of this writing, gross domestic product for
1998 is likely to have reached 3.8%, the same rate as 1996 and 1997. Ironically,
the same forces that weakened manufacturing stimulated demand--by deflating
import prices. This immunity to weakening U.S. exports is likely to be further
tested, as widespread weakness in commodity prices underscores a global economy
at risk of recession.

   Consumer spending continues to drive the U.S. economy; the savings rate
recently fell into negative territory. This may be an indication of just how
dependent the U.S. economy is on the strength of the stock market, since the
"wealth effect" of stock gains strongly affects consumers' perceptions of how
much they can afford to spend. If the corporate earnings outlook does not
improve, the wealth effect could dissipate.

   Bond market liquidity has improved, but may worsen again if any of a number
of potential problems arises: a further deterioration of Brazil's financial
condition, weakness in the U.S. stock market or further spread of the Asian
crisis. We expect the economy to grow more slowly in 1999, with inflation
remaining benign, and do not believe a recession is likely. In this economic
environment we foresee the 30-year Treasury bond trading within a 4.75-5.75%
range.

   Based on our outlook we believe the high-yield and U.S.
government/investment-grade sectors are poised to recover, and have weighted the
Fund toward these sectors (see allocation graph on page 3).

NOTES TO FINANCIAL STATEMENTS

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES


   PaineWebber Strategic Income Fund (the "Fund") is a series of PaineWebber
Securities Trust (the "Trust") which was organized under Massachusetts law by
a Declaration of Trust dated December 3, 1992 and is registered with the
Securities and Exchange Commission under the Investment Company Act of 1940,
as amended, as an open-end, diversified investment company. The Fund seeks
high level of current income and, secondarily, capital appreciation by
allocating its investments among three bond market categories: U.S. government
and investment grade corporate bonds; U.S.high yield, high risk corporate
bonds; and foreign and emerging market bonds.

   Costs incurred by the Fund in connection with its organization have been
deferred and are being amortized using the straight-line method over a period
not to exceed sixty months from the commencement of operations.

   Currently, the Fund offers Class A, Class B, Class C and Class Y shares.
Each class represents interests in the same assets of the Fund, and the
classes are identical except for differences in their sales charge structures,
ongoing service and distribution charges and certain transfer agency expenses.
In addition, Class B shares and all corresponding reinvested dividend shares
automatically convert to Class A shares approximately six years after
issuance. All classes of shares have equal voting privileges, except that each
class has exclusive voting rights with respect to its service and/or
distribution plan. Class Y shares have no service or distribution plan.

   The preparation of financial statements in accordance with generally
accepted accounting principles requires Fund 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 -- Securities may be valued by outside pricing
services approved by a management committee under the direction of the Board
of Trustees. The pricing service may utilize a matrix system incorporating
security quality, maturity and coupon as the evaluation model parameters,
and/or research and evaluations by its staff, including review of
broker-dealer market price quotations, if available, in determining what it
believes is the valuation of the portfolio securities valued by such pricing
service. Securities traded in the over-the-counter ("OTC") market and listed
on The Nasdaq Stock Market, Inc.("Nasdaq") are valued at the last trade price
on Nasdaq prior to the time of valuation. Other OTC securities are valued at
the last bid price available in the OTC market prior to the time of valuation.
The amortized cost method of valuation is used to value short-term debt
instruments with sixty days or less remaining to maturity. Securities which
are listed on U.S. and foreign stock exchanges are valued at the last sale
price on the day the securities are being 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 Mitchell Hutchins Asset Management Inc. ("Mitchell
Hutchins"), a wholly owned asset management subsidiary of PaineWebber
Incorporated ("PaineWebber") and investment adviser and administrator of the
Fund. Securities and assets for which market quotations are not readily
available (including restricted securities subject to limitations as to their
sale) are valued at fair value as determined in good faith under the direction
of the Trust's board of trustees. All investments quoted in foreign currencies
will be valued daily in U.S. dollars on the basis of the foreign currency
exchange rates prevailing at the time such valuation is determined by the
Fund's custodian.

NOTES TO FINANCIAL STATEMENTS


   Foreign currency exchange rates are generally determined prior to the close
of the New York Stock Exchange ("NYSE"). Occasionally, events affecting the
value of foreign investments and such exchange rates occur between the time at
which they are determined and the close of the NYSE, which will not be
reflected in the computation of the Fund's net asset value. If events
materially affecting the value of such securities or currency exchange rates
occur during such time period, the securities will be valued at their fair
value as determined in good faith by or under the direction of the Trust's
board of trustees.

   Repurchase Agreements--The Fund's custodian takes possession of the
collateral pledged for investments in repurchase agreements. 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. 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 by Mitchell Hutchins.

   Investment Transactions and Investment Income--Investment transactions are
recorded on the trade date. Realized gains and losses from investment
transactions and foreign exchange 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.

   Income, expenses (excluding class-specific expenses) and realized/unrealized
gains/losses are allocated proportionately to each class of shares based upon
the relative net asset value of outstanding shares (or the value of
dividend-eligible shares, as appropriate) of each class at the beginning of the
day (after adjusting for current capital share activity of the respective
classes). Class-specific expenses are charged directly to the applicable class
of shares.

   Foreign Currency Translation--The books and records of the Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis:

   (1) market value of investment securities, other assets and liabilities--at
the exchange rates prevailing at the end of the period.

   (2) purchases and sales of investment securities, income and expenses--at
the rates of exchange prevailing on the respective dates of such transactions.

   Although the Fund's net assets including the market values of the Fund's
investments are presented at the foreign exchange rates at the close of the
period, the Fund does not generally isolate the effect of fluctuations in
foreign exchange rates from the effect of the changes in market prices of
securities. However, the Fund does isolate the effect of fluctuations in
foreign exchange rates when determining the gain or loss upon the sale or
maturity of foreign currency-denominated debt obligations pursuant to federal
income tax regulations.

   Forward Foreign Currency Contracts--The Fund may enter into forward foreign
currency exchange contracts ("forward contracts") in connection with planned
purchases or sales of securities or to hedge the U.S. dollar value of
portfolio securities denominated in a particular currency.


                                                                              17
<PAGE>

NOTES TO FINANCIAL STATEMENTS


   The Fund has no specific limitation on the percentage of assets which may
be committed to such contracts. The Fund may enter into forward contracts or
maintain a net exposure to forward contracts only if (1) the consummation of
the contracts would not obligate the Fund to deliver an amount of foreign
currency in excess of the value of the position being hedged by such contracts
or (2) the Fund maintains cash, U.S. government securities or liquid debt
securities in a segregated account in an amount not less than the value of its
total assets committed to the consummation of the forward contracts and not
covered as provided in (1) above, as marked-to-market daily.

   Risks may arise upon entering into forward contracts from the potential
inability of counterparties to meet the terms of their forward contracts and
from unanticipated movements in the value of foreign currencies relative to the
U.S. dollar.

   Fluctuations in the value of forward contracts are recorded for book
purposes as unrealized gains or losses by the Fund. Realized gains and losses
include net gains and losses recognized by the Fund on contracts which have
matured.

   Futures Contracts--Upon entering into a financial futures contract, the
Fund is required to pledge to a broker an amount of cash and/or U.S.
Government securities equal to a certain percentage of the contract amount.
This amount is known as the "initial margin." Subsequent payments, known as
"variation margin," are made or received by the Fund each day, depending on
the daily fluctuations in the value of the underlying financial futures
contracts. Such variation margin is recorded for financial statement purposes
on a daily basis as unrealized gain or loss until the financial futures
contract is closed, at which time the net gain or loss is reclassified to
realized gain or loss.

   Using financial futures contracts involves various market risks. The
maximum amount at risk from the purchase of a futures contract is the contract
value. The Fund primarily uses financial futures contracts to manage duration
or for hedging purposes and not for leverage. However, imperfect correlations
between futures contracts and the portfolio securities being hedged or, market
disruptions, do not normally permit full control of these risks at all times.

   Option Writing--When a Fund writes a call or a put option, an amount equal
to the premium received by the Fund is included in the Fund's Statement of
Assets and Liabilities as an asset and as an equivalent liability. The amount
of the liability is subsequently marked-to-market to reflect the current
market value of the option written. If an option which the Fund has written
either expires on its stipulated expiration date or the Fund enters into a
closing purchase transaction, the Fund realizes a gain (or loss if the cost of
a closing purchase transaction exceeds the premium received when the option
was written) without regard to any unrealized gain or loss on the underlying
security, and the liability related to such option is extinguished. If a call
option which the Fund has written is exercised, the Fund realizes a capital
gain or loss (long-term or short-term, depending on the holding period of the
underlying security) from the sale of the underlying security and the proceeds
from the sale are increased by the premium originally received. If a put
option which a Fund has written is exercised, the amount of the premium
originally received reduces the cost of the security which the Fund purchases
upon exercise of the option.

   Dividends and Distributions to Shareholders--Dividends and distributions to
shareholders are recorded on the ex-dividend date. The amount of dividends and
distributions are determined in accordance with federal income tax regulations
which may differ from generally accepted accounting principles. 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.

CONCENTRATION OF RISK

   The ability of the issuers of debt securities held by the Fund to meet
their obligations may be affected by economic and political developments
particular to a specific industry, country or region. Mortgage securities may
decrease in value as a result of increases in interest rates and may benefit
less than other fixed-income securities from declining interest rates because
of risk of prepayments. Investing in securities of foreign issuers and
currency transactions may involve certain considerations and risks not
typically associated with investments in the United States. These risks
include revaluation of currencies, adverse fluctuations in foreign currency
values and possible adverse political, social and economic developments,
including those particular to a specific industry, country or region, which
could cause the securities and their markets to be less liquid and prices more
volatile than those of comparable U.S. companies and U.S. government
securities. These risks are greater with respect to securities of issuers
located in emerging market countries in which the Fund is authorized to
invest.

INVESTMENT ADVISER AND ADMINISTRATOR

   The Trust's board of trustees has approved an Investment Advisory and
Administration Contract ("Advisory Contract") with Mitchell Hutchins, under
which Mitchell Hutchins serves as investment adviser and administrator of the
Fund. In accordance with the Advisory Contract, the Fund pays Mitchell
Hutchins an investment advisory and administration fee, which is accrued daily
and paid monthly, at the annual rate of 0.75% of the Fund's average daily net
assets. At November 30, 1998, the Fund owed Mitchell Hutchins $67,801 in
investment advisory and administration fees.

DISTRIBUTION PLANS

   Mitchell Hutchins is the distributor of the Fund's shares and has appointed
PaineWebber as the exclusive dealer for the sale of those shares. Under
separate plans of distribution pertaining to Class A, Class B and Class C
shares, the Fund pays Mitchell Hutchins monthly service fees at an annual rate
of 0.25% of the average daily net assets of Class B and Class C shares and
monthly distribution fees at an annual rate of 0.75% and 0.50% of the average
daily net assets of Class B shares and Class C shares, respectively. At
November 30, 1998, the Fund owed Mitchell Hutchins $61,951 in service and
distribution fees.

   Mitchell Hutchins also receives the proceeds of the initial sales charges
paid by the shareholders upon the purchase of Class A shares and the
contingent deferred sales charges paid by the shareholders upon certain
redemptions of Class B and Class C shares. Mitchell Hutchins has informed the
Fund that for the year ended November 30, 1998, it earned $257,467 in sales
charges.

                                                                              19

SECURITY LENDING

   The Fund may lend securities up to 33 1/3% of its total assets to qualified
institutions. The loans are secured at all times by cash, U.S. government
securities or irrevocable letters of credit that meet certain guidelines
established by Mitchell Hutchins, in an amount at least equal to the market
value of the securities loaned, plus accrued interest, determined on a daily
basis and adjusted accordingly. The Fund will retain record ownership of
loaned securities to exercise certain beneficial rights; however, the Fund may
bear the risk of delay in recovery of, or even loss of rights in, the
securities loaned should the borrower fail financially. The Fund receives
compensation, which is included in interest income, for lending its securities
from interest earned on the cash or U.S. government securities held as
collateral, net of fee rebates paid to the borrower plus reasonable
administrative and custody fees. For the year ended November 30,1998, the Fund
earned $25,721 for lending its securities and PaineWebber earned $8,573 as the
Fund's lending agent. At November 30, 1998, the Fund owed PaineWebber $1,564
for security lending fees.

   As of November 30, 1998, the Fund's custodian received cash and/or cash
equivalents having an aggregate value of $1,081,250 as collateral for
portfolio securities loaned which was invested in the following money market
funds:

   Number of
    Shares                                                      Value
   ---------                                                 ----------

  1,073,750  TempFund Portfolio..........................    $1,073,750
      7,500  Liquid Assets Portfolio.....................         7,500
                                                             ----------
                                                             $1,081,250
                                                             ----------
                                                             ----------


   The security out on loan was sold on November 30, 1998, and therefore is
not included in the Fund's portfolio of investments.

BANK LINE OF CREDIT

   The Fund may participate with other funds managed by Mitchell Hutchins in a
$200 million committed credit facility ("Facility") to be used for temporary
financing until the settlement of sale or purchase of portfolio securities,
the repurchase or redemption of shares of the Fund at the request of the
shareholders and other temporary or emergency purposes. In connection
therewith, the Fund has agreed to pay commitment fees on its pro rata portion
of the Facility. Interest is charged to the Fund at rates based on prevailing
market rates in effect at the time of borrowings. For the year ended November
30, 1998, the Fund did not borrow under the Facility.

TRANSFER AGENCY AND RELATED SERVICES FEES

   PaineWebber provides transfer agency related services to each Fund pursuant
to a delegation of authority from PFPC Inc., the Funds' transfer agent, and is
compensated for these services by PFPC Inc., not the Funds. For the year ended
November 30, 1998, PaineWebber received from PFPC, Inc., approximately 48% of
the total transfer agency and related services fees collected by PFPC.

INVESTMENTS IN SECURITIES

   For federal income tax purposes, the cost of securities owned at November
30, 1998, was substantially the same as the cost of securities for financial
statement purposes.

   At November 30, 1998, the components of the net unrealized depreciation of
investments were as follows:

Gross appreciation (investments having an excess
 of value over cost) ................................    $ 3,567,276
Gross depreciation (investments having an excess 
 of cost over value) ................................     (7,449,428)
                                                         -----------
   Net unrealized depreciation of investments........    $(3,882,152)
                                                         -----------
                                                         -----------

   For the year ended November 30, 1998, total aggregate purchases and sales
of portfolio securities, excluding short-term securities, were as follows:
   Purchases ........................................    $222,401,096
   Sales ............................................    $187,414,518

FEDERAL TAX STATUS

   The Fund intends to distribute 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, capital gains and certain other amounts, if
any, the Fund intends not to be subject to a federal excise tax.

   At November 30, 1998, the Fund had a net capital loss carryforward of
$8,272,790 that will expire between November 30, 2002 and November 30, 2006.
This loss carryforward is available as a reduction, to the extent provided in
the regulations, of future net realized capital gains. To the extent that such
losses are used to offset future net realized capital gains, it is probable
these gains will not be distributed.

   To reflect reclassifications arising from permanent "book/tax" differences
for the year ended November 30, 1998, undistributed net investment income was
increased by $358,106, accumulated net realized gains/losses was decreased by
$355,303, and beneficial interest was decreased by $2,803. Permanent book/tax
differences are primarily attributable to foreign currency gains/losses.


                                                                              21

*   Annualized

(1) Total investment return is calculated assuming a $1,000 investment on the
    first day of each period reported, reinvestment of all dividends and other
    distributions at net asset value on the payable dates and a sale at net
    asset value on the last day of each period reported. The figures do not
    include sales charges; results would be lower if sales charges were
    included. Total investment return for periods of less than one year has not
    been annualized.

(2) During the year ended November 30, 1997 Mitchell Hutchins waived a portion
    of its advisory and administration fees. If such waivers had not been made
    the annualized ratios of expenses to average net assets would have been
    1.66% for Class A, 2.45% for Class B and 2.18% for Class C shares.

PAINEWEBBER STRATEGIC INCOME FUND


REPORT OF PRICEWATERHOUSECOOPERS LLP
INDEPENDENT ACCOUNTANTS


To the Shareholders and Trustees of
PaineWebber Strategic Income Fund

In our opinion, the accompanying statement of assets and liablilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of PaineWebber Strategic Income Fund
(the "Fund") at November 30, 1998, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the periods
indicated, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at
November 30, 1998 by correspondence with the custodian and brokers, provide a
reasonable basis for the opinion expressed above.

PAINEWEBBER STRATEGIC INCOME FUND


TAX INFORMATION


     We are required by Subchapter M of the Internal Revenue Code of 1986, as
amended, to advise you within 60 days of the Fund's fiscal period end (November
30, 1998), as to the federal tax status of distributions received by
shareholders during such fiscal year. Accordingly, we are advising you that all
of the distributions paid by the Fund during the period were derived from net
investment income and are taxable as ordinary income.

     Dividends received by tax-exempt recipients (e.g., IRAs and Keoghs) need
not be reported as taxable income. Some retirement trusts (e.g., corporate,
Keogh and 403(b)(7) plans) may need this information for their annual reporting.

     Because the Fund's fiscal year is not the calendar year, another
notification will be sent in respect of calendar year 1998. The second
notification, which reflects the amount to be used by calendar year taxpayers on
their federal income tax returns, will be made in conjunction with Form 1099 DIV
and will be mailed in January 1999. Shareholders are advised to consult their
own tax advisors with respect to the tax consequences of their investment in the
Fund.


                                                                              27
