Dear Stockholder:

      Enclosed is a combined  proxy  statement  and  prospectus  that seeks your
approval of an important proposal for your Fund. YOUR VOTE ON THIS PROPOSAL WILL
HELP DECIDE THE FUND'S FUTURE.

      The Board of Directors of Managed High Yield Fund Inc. ("High Yield Fund")
proposes that High Yield Fund reorganize  ("merge") into Managed High Yield Plus
Fund Inc. ("Plus Fund").  Under the proposed  merger,  each  stockholder of High
Yield Fund would become a holder of shares of common stock of Plus Fund and High
Yield Fund would be liquidated.

      High Yield Fund and Plus Fund are closed-end  investment  companies listed
on the New York Stock Exchange.  The Funds have substantially similar investment
objectives  and  invest  primarily  in  the  same  markets.  High  Yield  Fund's
investment  objective  is high  current  income  while  Plus  Fund has a primary
investment  objective  of high  income  with a  secondary  objective  of capital
appreciation.  However,  Plus Fund uses leverage to attempt to enhance yield and
has the ability to invest to a greater  extent in lower-rated  securities.  This
has enabled Plus Fund to provide a higher yield than High Yield Fund. High Yield
Fund's  Board  believes  that  combining  the two Funds will  benefit High Yield
Fund's  stockholders by providing them economies of scale,  the potential to use
leverage  to enhance  yield and greater  investment  flexibility.  The  proposed
merger,  the  investment  policies  of the  Funds  and the use of  leverage  are
described in more detail in the combined proxy statement and prospectus.

      AFTER CAREFUL CONSIDERATION,  THE BOARD OF HIGH YIELD FUND HAS UNANIMOUSLY
APPROVED THE PROPOSAL. THE BOARD RECOMMENDS THAT YOU READ THE ENCLOSED MATERIALS
CAREFULLY AND THEN VOTE "FOR" THE MERGER.

      The enclosed  document  describes the proposed merger and compares the two
Funds'  investment  objectives,  operating  expenses and performance  histories.
Please read the document carefully. I appreciate that the length of the attached
document  may be  daunting,  but we have  tried to make it as clear as  possible
while  meeting  all of the legal  requirements.  We have  included  a section of
questions  and  answers  that we  think  will  interest  most  investors.  After
reviewing  the  document,  please  complete,  date and sign your  proxy card and
return it in the enclosed postage-paid return envelope.

      YOUR VOTE IS VERY  IMPORTANT.  Please take a moment to review the enclosed
materials and to date, sign and return your proxy card TODAY. Voting your shares
early will permit High Yield Fund to avoid costly  follow-up  mail and telephone
solicitation.

      We have retained an outside firm that specializes in proxy solicitation to
assist us in connection with the proposed  merger.  If we have not received your
vote as the meeting  date  approaches,  you may  receive a  telephone  call from
Shareholder  Communications  Corporation  to ask for your vote. We hope that the
telephone call does not inconvenience you.

      As  always,  I thank  you for  being  an  investor  in our  Funds.  We are
committed to serving your interests and appreciate your trust in us.


                                                Very truly yours,



                                                /s/ Margo N. Alexander

                               QUESTIONS & ANSWERS

Q:  WHY IS THIS MERGER BEING PROPOSED?

A: High Yield Fund (PHT)  stockholders  would  benefit from the  opportunity  to
become  stockholders of a Fund that has historically  traded at a lower discount
in the market and has provided  higher income.  Through January 2000, High Yield
Fund traded at an average discount of -5.11% from its inception in November 1993
and traded at an average  discount of -5.70% from Plus Fund's (HYF) inception in
June 1998. Plus Fund has had an average  discount of -2.2% from its inception in
June 1998 through January 2000. In addition,  High Yield Fund has had an average
NAV yield of 11.36% from June 1998 through  January 2000,  while Plus Fund's NAV
yield has  averaged  12.54%  during  the same  period.  (The  average  NAV yield
represents  an average of the 12-month NAV yield  calculated  at the end of each
month;  the  12-month  NAV  yield  is  calculated  by  multiplying  the  month's
distribution  by 12 and dividing by the month-end  NAV).  During the period from
June 1998 through  January 2000,  the total returns based on NAV were -3.85% for
High Yield Fund and -3.37% for Plus Fund. To summarize, since its inception Plus
Fund has  provided a higher NAV yield and a better  total  return and has traded
closer to its NAV than has High Yield Fund.  In  addition,  both Funds and their
stockholders  would  benefit from the economies of scale and  opportunities  for
broader diversification that a larger asset base would provide.

      The chart below gives a history of the  premium/discount  of the two Funds
since their  respective  inception  dates.  Since Plus Fund's  inception  it has
consistently traded closer to its NAV than has High Yield Fund.

Q:  HOW CAN PLUS FUND ENHANCE ITS YIELD WITH LEVERAGE?

A: Plus Fund can enhance its yield  through  leverage  because the Fund  borrows
money at interest  rates that  generally are lower than the yield it receives on
its  investments.  For example,  Plus Fund's  average cost of borrowing  for the
12  months ended  January  31, 2000  was 5.69%  and it  had an average  yield on
its  investments  during  that period of 11.98%.  The Fund and its  stockholders
benefit  from  the  incremental  yield  on the  investments  purchased  with the
proceeds of the borrowings.

OF COURSE,  THE USE OF LEVERAGE  PRESENTS  RISKS.  IF THE FUND'S  AVERAGE  TOTAL
RETURN (THAT IS, YIELD PLUS CAPITAL GAIN OR LOSS) ON THE  INVESTMENTS  PURCHASED
WITH THE PROCEEDS OF THE BORROWINGS IS LESS THAN ITS AVERAGE COST OF BORROWINGS,
THE FUND'S TOTAL RETURN,  AS WELL AS THE AMOUNT  AVAILABLE FOR  DISTRIBUTION  TO
STOCKHOLDERS, WILL BE LOWER THAN IF LEVERAGE HAD NOT BEEN USED.


<PAGE>

Q:  HOW WILL THE MERGER AFFECT THE FUNDS' EXPENSES?

A: The combined Fund will have a larger asset base than High Yield Fund,  and as
a result,  its operating  expenses  (other than  interest and related  borrowing
expenses) are expected to represent a smaller  percentage of its net assets than
are High Yield Fund's  operating  expenses.  Because the combined  Fund will use
leverage,  it will incur  interest  expenses that High Yield Fund does not incur
and, as a result,  its overall  expenses  will be higher.  The use of  leverage,
however,  has enabled Plus Fund to provide its stockholders  with a yield higher
than that provided by High Yield Fund.

      The following table shows  pre-borrowing  expenses for the 12 months ended
January 31, 2000 for each Fund and on a PRO FORMA basis for the  combined  Fund,
along with a comparison of net assets and net asset values. Fee and expense data
is  expressed  as a percentage  of net assets.  For more details  about fees and
expenses, see Comparison of Funds - Fees and Expenses on page 18 of the combined
proxy statement/prospectus.

(1)  Reflects Plus Fund's  outstanding  borrowings of  approximately  27% of its
     total assets  (including the amount obtained  through  leverage) for the 12
     months  ended  January 31, 2000 and  assumes the  combined  Fund would have
     borrowed the same  percentage of its total  assets.  Plus Fund pays and the
     combined Fund will pay investment  advisory and  administrative  fees at an
     annual  rate of 0.70% of the Fund's  "managed  assets" - that is, its total
     assets  less only those  liabilities  that are not  borrowings.  Thus,  the
     investment  advisory and  administrative  fees increase  in relation to the
     additional managed assets acquired through leverage.

(2)  After giving  effect to  borrowings  of  approximately  27% of total assets
     (including the amount obtained through  leverage) at the same interest rate
     as that paid by Plus Fund  during the 12 months  ended  January  31,  2000,
     total  operating  expenses  for Plus Fund were  3.46%  and,  on a PRO FORMA
     basis, for the combined Fund would have been 3.45%.

Q:  HOW MANY SHARES WILL I RECEIVE IN THE MERGER?

A: If the merger is approved and you  participate in High Yield Fund's  Dividend
Reinvestment  Plan,  you will  receive full and  fractional  shares of Plus Fund
having an aggregate  net asset value equal to the  aggregate  net asset value of
the  High  Yield  Fund  shares  you  owned  prior to the  merger.  If you do not
participate in High Yield Fund's  Dividend  Reinvestment  Plan, you will receive
full  shares of Plus Fund  having a net asset  value  that  (together  with cash
received in lieu of fractional  shares)  equals the aggregate net asset value of
the High Yield Fund shares you owned prior to the merger.  Net asset values will
be calculated as of the closing date. Because the exchange of shares is based on
the Funds' net asset  values and not their market  prices,  you may receive Plus
Funds' shares with an  aggregate  market value on the date of the merger that is
higher  or  lower  than the  market  value of the High  Yield  Fund  shares  you
previously held. The reason for this difference is that the market prices of the
Funds' shares in relation to their net asset  values are likely to be different;
I.E., they are likely to trade at different discounts or premiums.

Q:  WILL THE MERGER SUBJECT ME TO ANY TAXES?

A: The merger has been structured as a tax-free transaction, which means no gain
or loss will be recognized by either Fund.  In addition,  you will  recognize no


<PAGE>

gain or loss as a result of your  acquisition  of Plus Fund  shares  through the
merger,  except with respect to any cash received in lieu of a fractional  share
of Plus Fund. If you do not wish to receive Plus Fund shares in the merger,  you
are free to sell your High Yield Fund shares  prior to the closing  (expected to
occur on or about May 26, 2000).

Q:  DO I NEED TO SURRENDER MY SHARE CERTIFICATES NOW?

A: No.  Please do not send in any share  certificates  at this time.  High Yield
Fund's transfer agent will mail you instructions and a letter of transmittal for
use in surrendering  your share  certificate(s)  for a certificate  representing
Plus Fund shares and, if applicable, cash.

Q:  WHAT IS MY BOARD'S RECOMMENDATION?

A:  Your Board of Directors recommends a vote "FOR" the merger.

                     COMBINED PROXY STATEMENT AND PROSPECTUS

                              Dated: March 30, 2000

         This    combined    Proxy    Statement    and    Prospectus     ("Proxy
Statement/Prospectus")  is being  furnished in connection with a Special Meeting
of Stockholders of Managed High Yield Fund Inc. ("High Yield Fund"),  a Maryland
corporation,  to be held on April 24, 2000, at 1285 Avenue of the Americas, 14th
Floor,  New York,  NY 10019 at 10:00 a.m.,  Eastern  time (such  meeting and any
adjournments  thereof are referred to as the  "Meeting").  At the  Meeting,  the
stockholders  of High  Yield Fund are being  asked to  consider  and  approve an
Agreement and Plan of Reorganization and Termination  ("Plan") that provides for
the  reorganization  of High Yield Fund into  Managed  High Yield Plus Fund Inc.
("Plus Fund"), also a Maryland corporation ("Reorganization").  (High Yield Fund
and Plus Fund are  collectively  referred to as  "Funds.") A form of the Plan is
attached as Appendix A to this Proxy Sttement/Prospectus. The Board of Directors
("Board") of High Yield Fund has  unanimously  approved the Plan as being in the
best interests of High Yield Fund and its stockholders.

         Pursuant to the Plan,  High Yield Fund will  transfer all its assets to
Plus Fund,  which will assume all the  liabilities of High Yield Fund. Each High
Yield Fund  stockholder  will  receive  the  number of full  shares of Plus Fund
common stock ("Plus Fund Shares"), plus either fractional shares (for High Yield
Fund  stockholders  that participate in High Yield Fund's Dividend  Reinvestment
Plan) or cash in lieu of any  fractional  shares  (for all other High Yield Fund
stockholders),  having  an  aggregate  net  asset  value  ("NAV")  that,  on the
effective  date of the  Reorganization,  is  equal to the  aggregate  NAV of the
stockholder's  shares of common  stock of High  Yield  Fund  ("High  Yield  Fund
Shares").  High Yield Fund  stockholders  will recognize no gain or loss, except
with respect to any cash received in lieu of fractional Plus Fund Shares.

         The NAV of each High Yield Fund  stockholder's  account  with Plus Fund
immediately after the  Reorganization,  including any cash received in lieu of a
fractional  Plus Fund Share,  will be the same as the NAV of such  stockholder's
High Yield Fund Shares immediately prior to the Reorganization. The market price
of the shares of EITHER Fund, however, may be higher or lower than the per share
NAV of that  Fund.  As a result,  while  the  total NAV of shares  owned by each
stockholder after the  Reorganization  will be the same, the market value of the
Plus  Fund  Shares  that  a  High  Yield  Fund   stockholder   receives  in  the
Reorganization  may be more or less than the market value of the High Yield Fund
shares that such stockholder owns immediately before the Reorganization.

         The Funds are diversified,  closed-end  management investment companies
with  substantially  similar  investment  objectives.   Plus  Fund's  investment
objective is to seek high income and, secondarily,  capital  appreciation.  High
Yield Fund's  investment  objective is to seek high current  income.  Both Funds


<PAGE>

seek  to  achieve  their  investment  objectives  by  investing  primarily  in a
diversified  portfolio of lower-rated,  income-producing debt and related equity
securities.  Both  Funds  may  invest  in the  securities  of  foreign  issuers,
including foreign issuers in emerging market countries.

         This Proxy  Statement/Prospectus sets forth the information that a High
Yield Fund stockholder  should know before voting on the Plan. It should be read
carefully and retained for future reference.

         A Statement  of  Additional  Information  ("SAI")  dated March 30, 2000
containing  additional  information  about  Plus  Fund has been  filed  with the
Securities  and  Exchange  Commission  ("SEC")  and is  hereby  incorporated  by
reference  in its  entirety  into this  Proxy  Statement/Prospectus.  The Annual
Report to  Stockholders of Plus Fund for the fiscal year ended May 31, 1999, and
the  Semi-Annual  Report to  Stockholders  of Plus Fund for the six months ended
November 30, 1999,  are on file with the SEC and are  incorporated  by reference
into this Proxy Statement/Prospectus.  The Annual Report to Stockholders of High
Yield Fund for the fiscal  year ended July 31,  1999 is on file with the SEC and
is  incorporated  by  reference  into  this  Proxy  Statement/Prospectus.  These
documents are available  without  charge by writing to Mitchell  Hutchins  Asset
Management  Inc., 51 West 52nd Street,  New York, NY  10019-6114,  or by calling
1-800-852-4750. The SEC maintains a Web site at http://www.sec.gov that contains
the documents  described above and other  information  about High Yield Fund and
Plus Fund.  Additional  information about both Funds may also be obtained on the
Web at  http://www.painewebber.com.  The shares of High Yield Fund and Plus Fund
are listed and publicly traded on the New York Stock Exchange ("NYSE"). Reports,
proxy statements and other information  concerning the Funds may be inspected at
the offices of the NYSE.

         AS  WITH  ALL  INVESTMENT  COMPANIES,  THE  SEC  HAS  NOT  APPROVED  OR
DISAPPROVED THESE SECURITIES OR DETERMINED IF THIS PROXY STATEMENT/PROSPECTUS IS
TRUTHFUL OR COMPLETE. TO STATE OTHERWISE IS A CRIME.

                                  INTRODUCTION

         This    combined    Proxy    Statement    and    Prospectus     ("Proxy
Statement/Prospectus")  is being furnished to stockholders of High Yield Fund in
connection with the solicitation of proxies by the Board for use at the Meeting.
All properly  executed and  unrevoked  proxies  received in time for the Meeting
will be voted in  accordance  with the  instructions  contained  therein.  If no
instructions  are  given,  shares  represented  by proxies  will be voted  "FOR"
approval  of the Plan.  The  presence  in person or by proxy of High  Yield Fund
stockholders entitled to cast a majority of all the votes entitled to be cast at
the Meeting will constitute a quorum.  If a quorum is not present at the Meeting
or a quorum is present but sufficient votes to approve the proposal described in
this Proxy  Statement/Prospectus  are not received, the persons named as proxies
may  propose  one  or  more  adjournments  of  the  Meeting  to  permit  further
solicitation of proxies.  Any such adjournment will require the affirmative vote
of a majority  of the shares  represented  at the Meeting in person or by proxy.
The persons  named as proxies will vote those  proxies that they are entitled to
vote  "FOR" the  proposal  in favor of such an  adjournment  and will vote those
proxies required to be voted "AGAINST" the proposal against such adjournment.

         High Yield Fund intends to mail this Proxy Statement/Prospectus and the
accompanying proxy card on or about April 4, 2000.

         Approval of the Plan requires the affirmative vote of a majority of the
votes entitled to be cast on the proposal.

         Broker  non-votes are shares held in "street name" for which the broker
indicates that instructions have not been received from the beneficial owners or
other  persons  entitled  to  vote  and for  which  the  broker  does  not  have
discretionary voting authority. Abstentions and broker non-votes will be counted
as shares present at the Meeting for quorum  purposes but will not be considered
votes cast at the Meeting.  Abstentions  and broker  non-votes  are  effectively
votes  against the Plan because the required  affirmative  vote is a majority of
the total shares outstanding.

         Any person  giving a proxy has the power to revoke it at any time prior
to its  exercise by  executing a  replacement  proxy or by  submitting a written
notice of revocation to the  Secretary of High Yield Fund  ("Secretary").  To be
effective,  such  revocation  must be  received  by the  Secretary  prior to the
Meeting  and must  indicate  the  stockholder's  name  and  account  number.  In
addition,  although mere  attendance  at the Meeting will not revoke a proxy,  a
stockholder  present at the Meeting may  withdraw  his or her proxy by voting in
person.

         Stockholders  of record as of the close of business on January 25, 2000
("Record Date"), are entitled to vote at the Meeting.  On the Record Date, there
were  6,031,667  outstanding  shares of common  stock of High Yield Fund  ("High
Yield Fund  Shares").  Each  stockholder  is  entitled to one vote for each full
share held and a fractional vote for each fractional  share held. As of March 1,
2000,  Mitchell  Hutchins  Asset  Management  Inc.  ("Mitchell  Hutchins"),  the
investment  adviser of both High  Yield Fund and Plus Fund,  did not know of any
person who owned beneficially 5% or more of either Fund's outstanding shares. As
of that same date, the Directors and officers, as a group, owned less than 1% of
either Fund's outstanding shares.

         High Yield Fund has engaged the services of Shareholder  Communications
Corporation ("SCC") to assist it in the solicitation of proxies for the Meeting.
High Yield Fund expects to solicit  proxies  principally  by mail, but it or SCC
may also solicit proxies by  telephone, facsimile  or e-mail.  High  Yield  Fund


<PAGE>

officers and employees of Mitchell Hutchins who assist in the proxy solicitation
will not receive any  additional or special  compensation  for any such efforts.
SCC will be paid  approximately  $35,000 for proxy solicitation  services.  High
Yield Fund and Plus Fund will bear the expenses  incurred in connection with the
Reorganization, which are estimated to be $245,000. High Yield Fund will request
broker/dealer  firms,  custodians,  nominees and  fiduciaries  to forward  proxy
materials to the beneficial owners of the shares held of record by such persons.
High Yield Fund may reimburse such broker/dealer firms, custodians, nominees and
fiduciaries for their reasonable expenses incurred in connection with such proxy
solicitation.

                                    SYNOPSIS

         The  following  is a summary of  certain  information  relating  to the
proposed  reorganization,  and is qualified  by  reference to the more  complete
information  contained  elsewhere  in the  Proxy  Statement/Prospectus  and  the
Appendices attached hereto.

         SPECIAL MEETING. This Proxy  Statement/Prospectus is being furnished to
stockholders of High Yield Fund in connection  with the  solicitation of proxies
by the Board for use at the Meeting to be held April 24,  2000 at [10:00]  a.m.,
Eastern time, and any adjournments thereof. At the Meeting, stockholders will be
asked to  consider  and  approve an  Agreement  and Plan of  Reorganization  and
Termination  ("Plan")  that provides for the  reorganization  of High Yield Fund
into Plus Fund, as described below.  Only stockholders of record as of the close
of  business  on the  Record  Date are  entitled  to vote at the  Meeting.  Each
stockholder  is entitled  to one vote for each full share held and a  fractional
vote for each fractional share held. All properly executed and unrevoked proxies
received  in  time  for the  Meeting  will  be  voted  in  accordance  with  the
instructions contained therein. If no instructions are given, shares represented
by proxies will be voted "FOR"  approval of the Plan.  Any person giving a proxy
has the power to revoke it at any time  prior to its  exercise  by  executing  a
superseding  proxy or by  submitting  a  written  notice  of  revocation  to the
Secretary of High Yield Fund.

         PROPOSED  REORGANIZATION.  The  Board  proposes  that High  Yield  Fund
reorganize  into  Plus  Fund and that  High  Yield  Fund's  stockholders  become
stockholders  of Plus Fund.  The  outstanding  High Yield  Fund  Shares  will be
converted  into an  equivalent  dollar  amount of full shares of common stock of
Plus Fund  ("Plus Fund  Shares"),  plus  fractional  shares (for High Yield Fund
stockholders that participate in High Yield Fund's Dividend  Reinvestment  Plan)
or  cash in lieu of any  fractional  shares  (for  all  other  High  Yield  Fund
stockholders),  all computed  based on the net asset value  ("NAV") per share of
each Fund on the closing date ("Closing  Date").  An exchange of High Yield Fund
Shares for Plus Fund  Shares at NAV may  result in High Yield Fund  stockholders
receiving  Plus Fund Shares with an  aggregate  market  value on the date of the
exchange  that is higher or lower than the  market  value of their  shares.  The
reason for this  difference  is that the market  prices of the Funds'  shares in
relation to their NAVs are likely to be different;  i.e.,  the Funds' shares are
likely to trade at different discounts or premiums.

         No sales  charge or fee of any kind will be  charged to High Yield Fund
stockholders  in  connection  with  their  receipt  of Plus  Fund  Shares in the
Reorganization.  Neither Fund will recognize any gain or loss for federal income
tax  purposes  due  to  the  Reorganization.   In  addition,   High  Yield  Fund
stockholders  will not  recognize  any gain or loss,  except with respect to any
cash received in lieu of a fractional share.

         The Reorganization is subject to a number of conditions, including High
Yield Fund  stockholder  approval and satisfaction of the terms of the Plan. The
Plan may be terminated and the Reorganization abandoned, whether before or after
approval by High Yield Fund stockholders, at any time prior to the Closing Date:


<PAGE>

(i) by the mutual  consent of each Fund's Board of Directors;  or (ii) by either
Fund (a) if the other Fund materially breaches any representation,  warranty, or
covenant contained in the Plan, (b) if the conditions to that Fund's obligations
under the Plan have not been  satisfied or waived,  or (c) if that Fund's Board,
in its sole discretion, determines that proceeding with the Reorganization would
not be in the  best  interests  of its  stockholders.  Unless  a  later  date is
mutually  agreed  upon by the Board of  Directors  of each  Fund,  the Plan will
terminate  automatically if the  Reorganization has not been consummated by July
31, 2000.

         THE PLAN.  Pursuant to the Plan,  High Yield Fund will transfer all its
assets to Plus Fund,  which will assume all the  liabilities of High Yield Fund,
and each High Yield Fund  stockholder  will receive the number of full Plus Fund
Shares and either cash or a fractional Plus Fund Share,  as appropriate,  having
an aggregate NAV that, on the effective date of the Reorganization,  is equal to
the aggregate NAV of the stockholder's High Yield Fund Shares. Immediately after
the Reorganization,  the NAV of each High Yield Fund stockholder's  account with
Plus Fund,  including any cash received in lieu of a fractional Plus Fund Share,
will be the  same  as the  NAV of such  stockholder's  High  Yield  Fund  Shares
immediately  prior to the  Reorganization.  High  Yield Fund  stockholders  will
recognize no gain or loss in  connection  with the  Reorganization,  except with
respect to any cash received in lieu of fractional Plus Fund Shares.

                                       2

         BOARD CONSIDERATIONS RELATING TO THE REORGANIZATION.  At their November
11,  1999 and  December  17,  1999  meetings,  the  Boards  considered  Mitchell
Hutchins'  assessments  of High  Yield  Fund and Plus  Fund and  considered  the
potential  benefits to each Fund if High Yield Fund were to reorganize into Plus
Fund. Mitchell Hutchins advised that both Funds' stockholders would benefit from
the economies of scale (I.E.,  lower operating expense ratios) and opportunities
for broader diversification that a larger asset base would provide. In addition,
Mitchell Hutchins advised that High Yield Fund's stockholders could benefit from
the  potential  to use  leverage  to  enhance  yield and from Plus  Fund's  more
flexible investment parameters. Further, the Reorganization itself could enhance
the ability of securities analysts to follow Plus Fund because it will eliminate
any confusion in the marketplace that results from two funds with  substantially
similar names,  investment  objectives and investment  policies being managed by
the same investment adviser.

         As part of its consideration, High Yield Fund's Board examined a number
of factors with respect to the Reorganization,  including: (1) the compatibility
of the Funds' investment objectives,  policies and restrictions;  (2) the Funds'
respective investment performances;  (3) the effect of the Reorganization on the
expense ratio of Plus Fund and that expense ratio  relative to High Yield Fund's
current expense ratio;  (4) the costs to be incurred by each Fund as a result of
the Reorganization; (5) the tax consequences of the Reorganization; (6) Mitchell
Hutchins'  assessment of the likely impact on High Yield Fund's  stockholders of
the  receipt of Plus Fund Shares at NAV;  and (7) the  continuity  of  portfolio
management.   The  Board  also   considered   the  potential   benefits  of  the
Reorganization to other persons, including Mitchell Hutchins and its affiliates.

         COMPARISON  OF  INVESTMENT  OBJECTIVES  AND POLICIES OF THE FUNDS.  The
investment  objectives  of High  Yield  Fund  and Plus  Fund  are  substantially
similar.  High Yield Fund's  investment  objective is high current  income.  The
primary  investment  objective of Plus Fund is high income,  while its secondary
objective is capital appreciation.

         Both Funds seek to achieve  their  investment  objectives  by investing
primarily in a diversified  portfolio of lower-rated,  income-producing debt and
related  equity  securities.  Both Funds may invest in the securities of foreign
issuers,  including foreign issuers in emerging market countries.  Each Fund may


<PAGE>

also engage in hedging strategies, such as options, futures and forward currency
contracts,  to attempt to reduce the overall risk of its  investment  portfolio,
enhance income,  realize gains or manage the Fund's foreign  currency  exposure.
Each Fund may also use interest rate swap  transactions to attempt to reduce the
overall risk of its investment portfolio.

         The primary  differences  in the Funds'  investment  policies  are Plus
Fund's use of  leverage  and its  greater  flexibility  in  choosing  the credit
quality of its portfolio.

         Plus Fund can borrow up to 33 1/3% of its total assets  (including  the
amount obtained through leverage) for investment purposes. It also may borrow an
additional  5% of its total assets (not  including  the amount so borrowed)  for
temporary or emergency purposes.  As of January 31, 2000, Plus Fund's borrowings
represented  about 31% of total  assets.  High Yield  Fund can  borrow  only for
temporary or emergency purposes,  and those borrowings are limited to 10% of its
total assets (not including the amount borrowed).  Historically, High Yield Fund
generally has not borrowed,  and it had no borrowings  outstanding as of January
31, 2000.

         High Yield Fund's  investment  policies require that it normally invest
at least 80% of its total assets in securities  that are rated BB or B by S&P or
comparably  rated by another  Rating  Agency.  Securities  rated BB or below are
commonly  referred to as "junk bonds." Only up to 20% of its total assets may be
invested in securities that are rated either above or below those levels or that
are unrated.  Plus Fund's investment policies require that it normally invest at
least 65% of its total  assets in  securities  that are rated at or below the BB
level, or equivalent unrated securities.  Unlike High Yield Fund, however,  Plus
Fund is not  limited in the  percentage  of its assets  that are rated  below B,
except that only 15% of its assets may be invested in securities  that are rated
as low as D (which  normally are in default at the time of purchase).  Plus Fund
also can invest up to 35% of its assets in  securities  that are rated  above BB
(that is, securities that are "investment grade").

         Although the  differences  in the two Funds'  investment  policies give
Plus Fund greater flexibility to adjust the credit quality of its portfolio, the
credit quality of the  securities  actually held by Plus Fund  historically  has
been within the range permitted under High Yield Fund's policies. Moreover, Plus
Fund's  current  ability to invest in the  lowest  quality  securities  (CCC and
lower) is somewhat limited by conditions imposed under its outstanding  leverage

Investment Risks of the Funds.)

                                       3

         COMPARISON  OF PRINCIPAL  RISK  FACTORS.  Both High Yield Fund and Plus
Fund are subject to the risks of investing  in U.S.  and foreign  bond  markets.
Plus Fund,  however,  is subject to additional  risks due to its use of leverage
and due to its  ability to invest  without  limit in  securities  that are rated
lower than B or the equivalent.

         LEVERAGE.  Leverage  creates  risks  for  stockholders,  including  the
likelihood  of greater  volatility  in the NAV and market  price of Plus  Fund's
shares and the risk that  fluctuations  in interest  rates on  indebtedness  may
adversely affect the return to stockholders. Plus Fund uses leverage; High Yield
Fund does not.

         Plus Fund  maintains a secured line of credit  pursuant to which it may
borrow up to  $200,000,000  for the  purpose of making  additional  investments.
During the 12 months ended January 31, 2000, the Fund has maintained outstanding
borrowings  under the line of credit in amounts  ranging  between  approximately
$135,000,000 and $175,000,000. These borrowings have represented between 26% and
32% of Plus  Fund's  total  assets.  Following  the  Reorganization,  Plus  Fund
anticipates  maintaining  its  leverage  within  a  range  of  26% to 31% of its
increased total assets.

         The  terms of Plus  Fund's  line of  credit  require  that it  maintain
collateral,  segregated  with the  Fund's  custodian  and  pledged to secure the
Fund's obligations under the line of credit, having a value that at all times is
equal to at least 250% of Plus Fund's  outstanding  borrowings under the line of
credit and to maintain  eligible assets having a value equal to at least 300% of
outstanding  borrowings.  The required collateral (as well as the assets used to
satisfy the 300% asset coverage requirement) must be comprised of Fund portfolio
assets (which may include assets acquired with the proceeds of borrowings)  that
satisfy certain eligibility  requirements.  Subject to certain  conditions,  the
Fund is able to substitute  eligible  collateral as necessary in order to effect
portfolio  transactions.  Mitchell  Hutchins  does not believe  that Plus Fund's
obligation to maintain  collateral  will impede the Fund's ability to manage its
assets in accordance with its investment objectives.

         To  the  extent  the  income  or  capital   appreciation  derived  from
securities  purchased  with funds  received  from  leverage  exceeds the cost of

<PAGE>

leverage,  the Fund's return will be greater than if leverage had not been used.
Conversely, if the income and capital appreciation from the securities purchased
with such funds is not  sufficient to cover the cost of leverage,  the return to
the Fund will be less than if leverage had not been used,  and,  therefore,  the
amount  available  for  distribution  to  stockholders  as  dividends  and other
distributions  will be  reduced.  Even in the  latter  case,  however,  Mitchell
Hutchins may decide to maintain Plus Fund's leveraged  position if it deems such
action to be appropriate under the circumstances.

         CREDIT QUALITY. Plus Fund may invest its entire portfolio in securities
rated  lower  than B or the  equivalent, while  High  Yield  Fund is  limited to
investing up to 20% of its total  assets in such  securities.

         Conversely,  High Yield Fund is also  limited to investing up to 20% of
its total assets in securities rated higher than BB or the equivalent,  compared
to 35% for Plus Fund.  Securities  rated below B have greater  risks and include
securities  in default or at greater  risk of  default.  Plus Fund may invest no
more than 15% of its total assets in securities  that are in default at the time
of purchase.

         FEDERAL  INCOME TAX  CONSIDERATIONS.  The Funds will not  recognize any
gain or loss for federal  income tax  purposes by reason of the  Reorganization.
Plus Fund's  acquisition of all High Yield Fund's assets in exchange  solely for
Plus Fund Shares (and cash in lieu of certain  fractional  Plus Fund Shares) and
Plus Fund's assumption of all High Yield Fund's liabilities, followed by the PRO
RATA  distribution  of Plus  Fund  Shares  and  cash or  fractional  shares,  as
appropriate,  to High Yield Fund  stockholders  constructively  in exchange  for
their High Yield  Fund  Shares,  will  qualify  as a  reorganization  within the
meaning of section 368(a)(1)(C) of the Internal Revenue Code of 1986, as amended
("Code"), and each Fund will be "a party to a reorganization" within the meaning
of section 368(b) of the Code. Plus Fund's basis for the acquired assets will be
the same as that of High Yield Fund immediately before the  Reorganization,  and
Plus Fund's  holding  period for the  acquired  assets will  include  High Yield
Fund's holding period therefor. A High Yield Fund stockholder's  aggregate basis
for the Plus Fund Shares to be received in the  Reorganization  will be the same
as the  aggregate  basis for the High  Yield  Fund  Shares to be  constructively
surrendered  in  exchange  for  those  Plus  Fund  Shares  less the basis of any
fractional  Plus Fund Share deemed sold.  The  stockholder's  holding period for
those Plus Fund Shares will include the holding period for those High Yield Fund
Shares,  provided  the  stockholder  held them as capital  assets on the Closing
Date.

                                       4

                      COMPARISON OF PRINCIPAL RISK FACTORS

PRIMARY DIFFERENCES IN INVESTMENT RISKS OF THE FUNDS

         High  Yield  Fund  and  Plus  Fund  invest  in  substantially   similar
securities  in the U.S.  and  foreign  bond  markets, and they  are  subject  to
substantially  the same  investment  risks.  Plus Fund,  however,  is subject to
additional  risks due to its use of leverage  and its ability to invest a larger
portion of its portfolio in lower-rated securities.

         LEVERAGE.  Plus  Fund is  authorized  to borrow  money  for  investment
purposes,  which constitutes leverage.  Leverage is a speculative technique that
increases Plus Fund's  exposure to risk of capital loss but that also creates an
opportunity for an increased yield for Plus Fund's  stockholders.  Plus Fund can
also borrow money for temporary or emergency purposes.  By contrast,  High Yield
Fund can only borrow money for temporary or emergency purposes.

<PAGE>

         Plus Fund may leverage up to 33 1/3% of its total assets (including the
amount  obtained  through  leverage),  but its  current  operating  policy is to
maintain  borrowings in an amount ranging  between  approximately  26-31% of its
total  assets.  Pursuant  to a  Revolving  Credit and  Security  Agreement  with
Corporate Receivables  Corporation,  Citibank,  N.A. and Citicorp North America,
Inc. ("Credit Agreement"), Plus Fund has obtained a secured line of credit under
which it can borrow up to $200,000,000  for investment  purposes.  During the 12
months ended January 31, 2000, the Fund maintained  outstanding borrowings under
this line of credit in amounts ranging between  approximately  $135,000,000  and
$175,000,000.  Those borrowings represented between approximately 26% and 32% of
Plus Fund's total assets.  As of January 31, 2000, Plus Fund had $167 million in
outstanding  borrowings,  representing about 31% of its total assets.  Following
the  Reorganization,  Plus Fund anticipates  increasing the dollar amount of its
borrowings  so as to maintain its  leverage  within a range of 26% to 31% of its
increased total assets.

         Pursuant to the Credit Agreement,  Plus Fund must maintain  collateral,
segregated  with  the  Fund's   custodian  and  pledged  to  secure  the  Fund's
obligations under the line of credit,  having a value that at all times is equal
to at least 250% of Plus Fund's outstanding borrowings under the line of credit.
Plus Fund also must  maintain  eligible  assets having a value equal to at least
300% of its  outstanding  borrowings.  The required  collateral  (as well as the
assets used to satisfy the 300% asset coverage requirement) must be comprised of
securities  (which may include assets acquired  with the proceeds of borrowings)
or other  assets  in the  Fund's  portfolio  that  satisfy  certain  eligibility
requirements.  For  example,  the Fund may not count more than 10% of its assets
invested in securities rated below CCC or the equivalent or more than 40% of its
assets invested in securities rated CCC or below or the equivalent toward either
requirement.

         Subject to certain conditions,  the Fund is able to substitute eligible
collateral as  necessary in  order to  effect portfolio  transactions.  Mitchell
Hutchins  does not believe that Plus Fund's  obligation  to maintain  collateral
will  impede the Fund's  ability  to manage  its assets in  accordance  with its
investment  objectives.  Similarly,  while the  collateral  and  asset  coverage
eligibility  requirements could limit the Fund's ability to invest in securities
rated CCC or below or the  equivalent,  Mitchell  Hutchins does not believe that
there  will be any  practical  effect on the  Fund's  ability to invest in these
securities to the extent desired by its portfolio managers.

         Capital raised  through  leverage is subject to interest  costs,  which
could  exceed the  income and  appreciation  on the  assets  purchased  with the
proceeds of the leverage. Under the Credit Agreement, Plus Fund pays interest at
a rate that normally is comparable to market  commercial  paper rates.  The Fund
also pays  certain  other  fees in  connection  with the line of  credit,  which
increase the cost of borrowing over the stated  interest  rate.  During the year
ended  January 31,  2000,  Plus Fund paid  interest  and other fees ranging from
5.24% to 6.43% on its outstanding borrowings.

                                       5

         Plus Fund's  borrowings under the Agreement and any other  transactions
involving  Fund  indebtedness  (other than  borrowings  of up to 5% of its total
assets for temporary or emergency  purposes) are considered "senior  securities"
for purposes of the Investment Company Act of 1940, as amended ("1940 Act"), and
constitute  leverage.  Unless the income and  capital  appreciation,  if any, on
assets  acquired with borrowed funds or other leverage  proceeds exceed the cost
of the  leverage,  the use of leverage  will  diminish  Plus  Fund's  investment
performance. Successful use of leverage depends on Mitchell Hutchins' ability to
predict  correctly  interest rates and market  movements.  There is no assurance
that the use of a leveraging  strategy will be  successful  during any period in
which it is used.

         Under the 1940 Act,  Plus Fund is not  permitted to borrow or otherwise
incur indebtedness  constituting senior securities unless immediately thereafter
the Fund has total assets  (including the proceeds of the indebtedness) at least
equal to 300% of the amount of the  indebtedness.  Stated  another way, the Fund
may not borrow for  investment  purposes  more than 33 1/3% of its total assets,
including the amount borrowed. The Fund must maintain this 300% "asset coverage"
for as long as the  indebtedness is outstanding.  The 1940 Act provides that the
Fund may not  declare  any cash  dividend  or other  distribution  on Plus  Fund
Shares,  or purchase any Plus Fund Shares  (through tender offers or otherwise),
unless it would satisfy this 300% asset coverage  after  deducting the amount of
the dividend,  other  distribution  or share purchase price, as the case may be.
The 300% asset coverage requirement under the 1940 Act is substantially the same
as the 300% asset  coverage  requirement  that is imposed on Plus Fund under its
Credit  Agreement,  except that assets used to satisfy the 1940 Act  requirement
are not subject to special eligibility requirements.

<PAGE>

         CREDIT QUALITY OF SECURITIES.  Plus Fund normally  invests at least 65%
of its total assets in (i) income producing debt securities that are rated lower
than Baa by  Moody's  Investors  Service,  Inc.  ("Moody's"),  lower than BBB by
Standard & Poor's,  a  division  of The  McGraw-Hill  Companies,  Inc.  ("S&P"),
comparably   rated  by  another   nationally   recognized   statistical   rating
organization  (collectively  with  Moody's and S&P,  "Rating  Agencies")  or, if
unrated,  determined to be of equivalent  quality by Mitchell  Hutchins and (ii)
equity  securities  (including  common stocks,  rights,  and warrants for equity
securities)  that are  attached to, or are part of a unit  including,  such debt
securities.  Plus Fund may  invest up to 15% of its total  assets in  securities
that  are  rated  as low as D  (which  normally  are in  default  at the time of
purchase). Plus Fund's ability to invest in securities rated CCC or lower or the
equivalent  is somewhat  limited by the asset  coverage  and other  requirements
under the Credit Agreement.  Mitchell Hutchins does not believe,  however,  that
these  requirements  will  prevent  Plus Fund from  investing  to the extent its
portfolio managers deem desirable in these lowest rated securities. In addition,
Plus  Fund  may  invest  up to 35% of  its  total  assets  in  investment  grade
securities  (I.E.,  securities rated Baa/BBB or higher) of private or government
issuers,  equity securities of lower-rated or comparable  issuers (issuers whose
debt  securities are  lower-rated or who Mitchell  Hutchins  determines to be of
comparable quality), money market instruments and municipal obligations.

         High Yield Fund  normally  invests at least 80% of its total  assets in
securities  rated  Ba or B by  Moody's,  BB or B by S&P or  comparably  rated by
another  Rating  Agency.  The Fund may  invest up to 20% of its total  assets in
securities rated higher or lower than these levels,  including  securities rated
as low as D, and in unrated  securities that Mitchell Hutchins  determines to be
of comparable  quality to rated  securities in which High Yield Fund can invest.
High Yield Fund also may acquire equity  securities when attached to, or as part
of a unit  including,  debt  securities,  or in connection  with a conversion or
exchange of debt securities.  High Yield Fund, however,  may not invest in other
equity securities.

         For both  Funds,  the  determination  of  whether  a  security  is in a
particular  rating category,  and whether the above  percentage  limitations are
met,  will  be  made  at the  time of  investment.  Mitchell  Hutchins  assesses
securities on the basis of the highest rating assigned by any Rating Agency.

                                       6

         Securities  rated BB or Ba are considered to be within the "upper tier"
of the high  yield,  high  risk  ("junk  bond")  income  securities  market  and
securities  rated B are  considered  to be in the "middle  tier" of this market.
Securities  within  these two tiers  constitute  the  largest  portions  of this
market.  Investments in securities that are rated Ca or lower by Moody's,  CC or
lower by S&P, and comparable  securities are extremely  speculative and involves
significant risk. Securities rated D and comparable unrated securities may be in
default at the time of  purchase.  These  securities  frequently  do not produce
income and may require the Funds to bear certain extraordinary expenses in order
to protect and recover  their  investment.  To the extent Plus Fund  pursues its
secondary  investment  objective of capital  appreciation  through investment in
these securities, its ability to achieve current income for its stockholders may
be diminished.

<PAGE>

RISKS COMMON TO BOTH FUNDS

         MARKET  PRICE  AND NET ASSET  VALUE OF  SHARES.  Shares  of  closed-end
investment companies, such as the Funds, frequently trade at a discount to their
NAVs.  Whether an investor  will realize gains or losses upon the sale of shares
of either Fund does not depend  directly  upon  changes in the Fund's  NAV,  but
rather upon  whether the market price of the shares at the time of sale is above
or below the investor's  purchase price for the shares. The market price of each
Fund's shares is determined by such factors as relative demand for and supply of
shares in the market,  general  market and economic  conditions,  changes in the
Fund's NAV and other factors beyond the control of the Fund. This market risk is
separate and distinct from the risk that each Fund's NAV may decrease.

         Due to  differences  in the market price and NAV of the Funds'  shares,
High Yield Fund  stockholders  who exchange their shares for Plus Fund Shares at
NAV may receive Plus Fund Shares with an  aggregate  market value that is higher
or lower than the market value of their High Yield Fund  Shares.  The reason for
this  difference  is that the  relative  market  prices of the Funds'  shares in
relation to their NAVs are likely to be different;  i.e.,  the Funds' shares are
likely to trade at different  discounts  or premiums.  As of March 17, 2000 High
Yield Fund Shares were  trading at a discount of 14.35%,  compared to 10.64% for
Plus Fund  Shares.  It is likely,  however,  that one or both of these  discount
levels will change by the  Closing  Date.  For a  comparison  to the  historical
trading  discounts and premiums for each Fund's shares,  see  "Comparison of the
Funds - Trading History - Share Price Data."

         The Funds'  shares are  designed  primarily  for  long-term  investors.
Investors in the Funds' shares should not view the Funds as vehicles for trading
purposes.

         LOWER-RATED   DEBT   SECURITIES.   Compared  to   higher-quality   debt
securities,  securities rated below investment grade, often referred to as "junk
bonds,"  involve  greater risk of default or price changes due to changes in the
credit  quality of the issuer  because they are  generally  unsecured and may be
subordinated to other  creditors'  claims.  There is a greater  possibility that
adverse changes in the financial condition of the issuer, or in general economic
conditions,  or both, or an unanticipated  rise in interest rates may impair the
ability of the issuers of these  securities  to make  payments  of interest  and
principal.  The value of junk bonds  often  fluctuates  in  response  to issuer,
political  or economic  developments  and can decline  significantly  over short
periods of time or during  periods of general or regional  economic  difficulty.
During those times, the bonds may be difficult to value or sell at a fair price.
Credit  ratings on junk bonds do not  necessarily  reflect  their actual  market
risk.

<PAGE>

         Changes in a Rating  Agency's  rating of any income  security or in the
ability of an issuer to make  payments of interest and principal may also affect
the value of these  investments.  Changes in the value of  portfolio  securities
generally  will not affect cash income  derived from such  securities,  but will
affect a Fund's  net asset  value.  The Funds do not  necessarily  dispose  of a
security  when its rating is reduced  below the rating at the time of  purchase,
although  Mitchell  Hutchins  monitors  all  investments  to  determine  whether
continued  investment  is  consistent  with the  Fund's  investment  objectives.
Because of the greater number of investment considerations involved in investing
in lower-rated  income  securities,  the  achievement  of the Funds'  investment
objectives depends more on Mitchell Hutchins' analytical abilities than would be
the case if it were  investing  primarily  in  securities  in the higher  rating
categories.

                                       7

         The values of lower-rated income securities, like those of other income
securities,  generally fluctuate in response to changes in interest rates. Thus,
a decrease in interest rates will  generally  result in an increase in the value
of such  securities.  Conversely,  during periods of rising interest rates,  the
value of such  securities  will generally  decline.  These  fluctuations  can be
expected  to be  greater  for  investments  in  income  securities  with  longer
maturities  than for investments in income  securities with shorter  maturities.
The secondary  market prices of  lower-rated  securities are often affected to a
lesser extent by changes in interest rates and to a greater extent by changes in
general  economic  conditions and business  conditions  affecting the issuers of
such securities and their respective industries.  Negative publicity or investor
perceptions may also adversely affect the values of lower-rated securities.

<PAGE>

         INVESTING  IN FOREIGN AND  EMERGING  MARKET  SECURITIES.  Each fund may
invest in foreign securities, including securities of issuers in emerging market
countries.  Investments in foreign  securities may be affected by, among others,
the following factors:

      o  CURRENCY  EXCHANGE  RATES - The dollar value of the Funds'  investments
         denominated  in foreign  currencies  will be affected by changes in the
         exchange  rates  between the dollar and the  currencies  in which those
         investments  are  traded.  Plus Fund may  invest up to 15% of its total
         assets  in  securities  denominated  in  foreign currencies, while High
         Yield Fund is limited to 10% of its net assets.

      o  POLITICAL  AND ECONOMIC  CONDITIONS  - The value of the Funds'  foreign
         investments   may  be  adversely   affected  by  political  and  social
         instability  in their home  countries  and by changes  in  economic  or
         taxation policies in those countries.

      o  REGULATIONS - Foreign companies generally are subject to less stringent
         regulations, including financial and accounting controls, than are U.S.
         companies.  As a result,  there  generally is less  publicly  available
         information  about  foreign  companies  than about U.S.  companies.  In
         addition, certain countries may impose expropriation constraints on the
         assets of certain companies.

      o  MARKETS - The  securities  markets of other  countries are smaller than
         U.S.  securities  markets.  As a result, many foreign securities may be
         less liquid and their prices may be more volatile than U.S. securities.

         The risks described above for foreign  securities may be more acute for
the Funds' investments in emerging market countries.  These countries  typically
have economic and political systems that are relatively less mature,  and can be
expected to be less stable, than those of developed countries. For example, many
emerging market  countries have in the past  experienced high rates of inflation
or sharply  devalued their currencies  against the U.S. dollar,  thereby causing
the value of  investments  in companies  located in those  countries to decline.
Emerging  market  countries  may  have  policies  that  restrict  investment  by
foreigners in those countries,  and there is a risk of government  expropriation
or nationalization  of private property.  The possibility of low or non-existent
trading  volume in the  securities  of  companies  in emerging  markets may also
result in a lack of  liquidity  and in price  volatility.  Issuers  in  emerging
markets  typically  are subject to a greater  degree of change in  earnings  and
business  prospects than are companies in developed  markets.  Transaction costs
are often higher in emerging market  countries and there may be additionsl risks
and delays in custody and settlement procedures.

<PAGE>

         ORIGINAL ISSUE DISCOUNT,  ZERO COUPON AND  PAYMENT-IN-KIND  SECURITIES.
The Funds may invest in discount  securities,  including zero coupon securities,
other securities issued with original issue discount ("OID") and payment-in-kind
("PIK")  securities.  Zero coupon securities pay no interest to holders prior to
maturity. When a zero coupon security is held to maturity, its entire investment
return comes from the  difference  between its  purchase  price and its maturity
value.  PIK  securities  may pay  interest  either  in  cash  or in the  form of
additional  securities.  The portion of the OID that  accrues  each year on zero
coupon and other OID  securities  in which a Fund  invests,  and the  "interest"
received or accrued on a Fund's PIK  securities,  must be included in its income
annually.  To continue to qualify for tax  treatment  as a regulated  investment
company under the Code ("RIC") and to avoid a federal  excise tax, each Fund may
be required to distribute  as dividends  amounts that are greater than the total
amount of cash it actually receives.  These  distributions must be made from the
Fund's cash assets or, if  necessary,  from the  proceeds of sales of  portfolio
securities.  As a  result,  each  Fund  may be  unable  to  purchase  additional
securities  with cash used to make such  distributions,  and its current  income
ultimately may be reduced as a result. Zero coupon, other OID and PIK securities
usually trade at a substantial discount from their face or par value and will be
subject to greater fluctuations of market value in response to changing interest
rates  than  debt  obligations  of  comparable   maturities  that  make  current
distributions of interest in cash.

                                       8

         CALL  FEATURES.  A substantial  portion of the  securities  held by the
Funds may  permit the issuer to  "call,"  or  redeem,  its  securities  prior to
maturity. If an issuer were to redeem securities held by a Fund during a time of
declining  interest  rates,  the Fund probably would not be able to reinvest the
proceeds in  securities  of comparable  quality  providing  the same  investment
return as the securities redeemed. The existence of a call feature may limit the
potential  for such a security to increase in value during  periods of declining
interest rates.

         PREMIUM SECURITIES.  The Funds may each invest a substantial portion of
their assets in securities  bearing coupon rates higher than  prevailing  market
rates. Such "premium"  securities are typically purchased at prices greater than
the principal  amounts  payable on maturity.  As a result,  the purchase of such
securities  provides  the  Funds  with  a  higher  level  of  investment  income
distributable  to  stockholders  on a current basis than if the Funds  purchased
securities bearing current market rates of interest.  If such premium securities
are called prior to maturity, the Funds may recognize a capital loss.

         HEDGING AND OTHER  STRATEGIES USING  DERIVATIVE  INSTRUMENTS.  Options,
futures contracts,  options on futures contracts, forward currency contracts and
interest rate swap  transactions  are  derivatives and their use entails special
risks. The value of "derivatives" - so called because their value "derives" from
the value of an  underlying  asset,  reference  rate or index - may rise or fall
more rapidly than other investments.  For some derivatives, it is possible for a
Fund to lose more than the amount it invested in the derivative.  If a Fund uses
derivatives  to adjust or  "hedge"  the  overall  risk of its  portfolio,  it is
possible that the hedge will not succeed.  This may happen for various  reasons,
including  unexpected  changes  in the  value  of the  derivatives  that are not
matched by opposite changes in the value of the rest of the Fund's portfolio.

           PROPOSAL: REORGANIZATION OF HIGH YIELD FUND INTO PLUS FUND


INFORMATION ABOUT THE REORGANIZATION

         Under the Plan,  High Yield Fund will  reorganize into Plus Fund Shares
and High Yield Fund's stockholders will become stockholders of Plus Fund.

         Each High Yield Fund  stockholder's  High  Yield  Fund  Shares  will be
converted  into an  equivalent  dollar  amount  of full Plus  Fund  Shares  plus
fractional Plus Fund Shares (for High Yield Fund  stockholders  that participate
in  High  Yield  Fund's  Dividend  Reinvestment  Plan)  or  cash  in lieu of any
fractional  Plus Fund Shares (for all other High Yield Fund  stockholders),  all
computed  based on the NAV per share of each Fund on the Closing  Date. No sales
charge or fee of any kind will be charged to High  Yield  Fund  stockholders  in
connection with their receipt of Plus Fund Shares in the Reorganization. Neither
Fund will recognize any gain or loss for federal income tax purposes as a result
of the  Reorganization.  High Yield Fund  stockholders will recognize no gain or
loss,  except with respect to any cash received in lieu of fractional  Plus Fund
Shares.

         The Reorganization is expected to occur on or about May 26, 2000, or on
such later date as the  parties  may agree in  writing.  The  Reorganization  is
contingent  both upon High Yield Fund  stockholder  approval  and upon each Fund
satisfying  the  terms  of the  Plan.  Under  Maryland  law,  stockholders  of a
corporation,  such as High  Yield  Fund,  whose  shares are traded on a national
securities  exchange  are not  entitled to demand the fair value of their shares
upon a merger;  therefore,  High  Yield Fund  stockholders  will be bound by the
terms of the Reorganization  under the Plan. However,  any stockholder of either
Fund may sell his or her shares of common  stock on the New York Stock  Exchange
("NYSE").  High Yield Fund Shares may not be listed on the NYSE or available for
trading there for several days prior to the Closing Date.

         After  the  Closing  Date,  High  Yield  Fund  will  deregister  as  an
investment  company under the 1940 Act and will terminate its separate existence
under  Maryland law. In addition,  High Yield Fund's shares of common stock will
be removed from listing on the NYSE and withdrawn  from  registration  under the
Securities Exchange Act of 1934, as amended ("Securities Exchange Act").

         The Plan may be terminated and the  Reorganization  abandoned,  whether
before or after approval by High Yield Fund's stockholders, at any time prior to
the Closing  Date:  (i) by the mutual  consent of the Board of Directors of each
Fund;  or (ii) by either  Fund (a) if the other  Fund  materially  breaches  any
representation,  warranty,  or  covenant  contained  in  the  Plan,  (b)  if the
conditions to that Fund's  obligations under the Plan have not been satisfied or
waived,  or (c) if that Fund's Board,  in its sole  discretion,  determines that
proceeding  with the  Reorganization  would not be in the best  interests of its
stockholders.  Unless  a later  date is  mutually  agreed  upon by the  Board of
Directors  of  each  Fund,  the  Plan  will  terminate  automatically,   if  the
Reorganization has not been consummated by July 31, 2000.

BOARD CONSIDERATIONS

         The  High  Yield  Fund  Board,  including  the  Directors  who  are not
"interested  persons,"  as that term is defined in the 1940 Act,  of either High
Yield  Fund or Plus Fund  ("Independent  Board  Members"),  determined  that the
Reorganization is in the best interests of High Yield Fund and voted unanimously
to recommend that stockholders approve the Plan.

<PAGE>

         Consistent with the policies set forth in High Yield Fund's Prospectus,
the Board from time to time  considers  whether it would be in the best interest
of the Fund to take actions  designed to eliminate or reduce the discount to NAV
at which the Fund's  shares trade and to otherwise  enhance  stockholder  value.
Such actions include a merger with another investment company,  conversion to an
open-end  investment  company,  open market share  repurchase  offers and tender
offers.  After  considering  various actions to address the trading discount and
maximize  stockholder  value,  High Yield  Fund's Board  unanimously  approved a
proposal to reorganize High Yield Fund into Plus Fund.

                                       10

         At the Boards' November 11, 1999 meetings,  Mitchell Hutchins presented
its  assessments  of High Yield Fund and Plus Fund and suggested that both Funds
could  benefit  from a  merger.  The  Boards of each  Fund  considered  Mitchell
Hutchins' evaluations and requested that Mitchell Hutchins make a final proposal
at a subsequent Board meeting.  Mitchell Hutchins recommended the Reorganization
to the  Boards  of High  Yield  Fund and Plus  Fund at  Board  meetings  held on
December 17, 1999. Mitchell Hutchins advised that both Funds' stockholders would
benefit from the economies of scale (i.e.,  lower operating  expense ratios) and
opportunities  for  broader  diversification  that a  larger  asset  base  would
provide.  They also noted that High Yield Fund's stockholders could additionally
benefit from the ability to use leverage through  borrowing.  Mitchell  Hutchins
also advised that the Reorganization would permit High Yield Fund's stockholders
to gain  the  added  flexibility  of Plus  Fund's  slightly  broader  investment
parameters.  Further,  the  Reorganization  itself could  enhance the ability of
securities  analysts to follow Plus Fund because it will eliminate any confusion
in the marketplace that results from two funds with substantially similar names,
investment  objectives  and  investment  policies  being  managed  by  the  same
investment adviser.

         As part of its  consideration,  the High Yield  Fund  Board  examined a
number  of  factors  with  respect  to the  Reorganization,  including:  (1) the
compatibility of the Funds'  investment  objectives,  policies and restrictions;
(2)  the  Funds'  respective  investment  performances;  (3) the  effect  of the
Reorganization on the expense ratio of Plus Fund and that expense ratio relative
to High Yield Fund's current expense ratio; (4) the costs to be incurred by each
Fund  as a  result  of the  Reorganization;  (5)  the  tax  consequences  of the
Reorganization;  (6) Mitchell Hutchins'  assessment of the likely impact on High
Yield Fund's stockholders of the receipt of Plus Fund Shares at NAV; and (7) the
continuity  of portfolio  management.  The Board also  considered  the potential
benefits of the Reorganization to other persons, including Mitchell Hutchins and
its affiliates.

         The Board  considered  the  investment  objectives  and policies of the
Funds and noted  that  their  portfolios  have had  substantially  similar  risk
profiles  based on the types of securities  the Funds have held. The Board noted
that Plus Fund is subject to greater  risk than High Yield Fund  because it uses
leverage and may invest to a greater extent in lower-rated  securities.  The use
of leverage  exposes Plus Fund to greater  risk (and greater  return) than other
investment  practices.  Despite these differences,  the Board concluded that the
Funds' investment  objectives and policies are reasonably  compatible.  Mitchell
Hutchins also informed the Board that it believed that the  additional  risks of
leverage  and of  investing  in  lower-rated  securities  were  warranted by the
opportunity for higher yields.


<PAGE>

         The Board  also took into  account  the  compatibility  of the  current
portfolio holdings of High Yield Fund and Plus Fund.  Mitchell Hutchins informed
the Board that the two Funds'  portfolios were  sufficiently  compatible that no
securities  would need to be sold to accommodate the  Reorganization.  The Board
also considered the level and quality of investment  advisory  services provided
by Mitchell Hutchins to both Funds and decided that Plus Fund stockholders would
benefit from Mitchell Hutchins'  continued  supervision of portfolio  management
services after the Reorganization.

         In addition,  the Board  considered  the historic  performance  of High
Yield  Fund in  relation  to the  performance  of Plus Fund.  Mitchell  Hutchins
advised the Board that, while past  performance  provides no guarantee of future
results, Plus Fund provided a greater total return based on net asset value than
High Yield Fund for the year ended January 31, 2000. Mitchell Hutchins indicated
that the yield for Plus Fund was higher as of the same date.

         The Board also considered the impact the  Reorganization  would have on
expenses. In analyzing expenses, the Board evaluated the investment advisory and
administration  fees  paid by the  Funds.  High  Yield  Fund and  Plus  Fund pay
investment  advisory  and  administrative  fees at  different  rates,  and  they
calculate their fees in different  ways. High Yield Fund pays Mitchell  Hutchins
investment  advisory and administration  fees, computed weekly and paid monthly,
of 0.90% of its average  weekly net  assets.  Plus Fund pays  Mitchell  Hutchins
fees,  computed  weekly and paid monthly,  of 0.70% of its average  weekly total
assets minus  liabilities  other than the  aggregate  indebtedness  constituting
leverage ("Managed  Assets").  The investment  advisory and administration  fees
payable to  Mitchell  Hutchins  when Plus Fund has  outstanding  borrowings  are
higher than when it does not because the fees are  calculated as a percentage of
Managed  Assets,  which  include  assets  purchased  with the  proceeds of those
borrowings. Mitchell Hutchins indicated to the Board that Plus Fund would likely
continue to borrow about 26-31% of the Fund's total assets (including the amount
obtained  by  leverage)  after  the  Reorganization,   assuming  similar  market
conditions.  The Board  recognized that, given the level of Plus Fund's expected
borrowings,  the effective investment advisory and administration fee rate would
exceed 0.90% of Plus Fund's weekly net assets. For example, at the level of Plus
Fund's average borrowings for the 12 months ended January 31, 2000 (27% of total
assets), the Fund paid Mitchell Hutchins a fee equal to an effective annual rate
of 0.96% of the Fund's average weekly net assets.  The Board recognized that the
use of  leverage  requires  greater  allocation  of  resources  within  Mitchell
Hutchins  and  concluded  that,  therefore,   a  slightly  higher  advisory  and
administrative  fee rate (when  expressed  as a  percentage  of net  assets) was
appropriate.

                                       11

         In  addition  to  considering  the  potential  increase  in the rate of
investment  advisory and administrative  fees (when expressed as a percentage of
net  assets),  the  Board  discussed  other  expenses  paid by High  Yield  Fund
stockholders.  Based on Mitchell Hutchins'  preliminary  calculations,  Mitchell
Hutchins  estimated that after the  Reorganization,  on a PRO FORMA basis,  Plus
Fund  Shares  would  have  total  operating  expenses,  excluding  interest  and
Reorganization  expenses,  that would be a lower  percentage  of net assets than
those of High Yield Fund.  The Board  noted,  however,  that the  Reorganization
would  result in an  increase  in total  annual  operating  expenses  (including
interest payments) for High Yield Fund  stockholders.  The Board also noted that
the operating expenses of the combined Fund, as a percentage of net assets, were
expected  to  be  lower  than  that  of  either  Fund,  excluding  interest  and
Reorganization  expenses.  In addition,  the Board considered Mitchell Hutchins'
assessment  that the yield of Plus Fund would likely be higher than that of High
Yield  Fund and  that the  relatively higher  yield should  serve to  offset the

<PAGE>

effect of the interest expense. For more information on the comparative fees
and expenses of the Funds,  see  "Comparison of the Funds -- Fees and Expenses,"
below.

         Mitchell   Hutchins  advised  the  Board  that  each  High  Yield  Fund
stockholder would receive full Plus Fund Shares,  plus cash or a fractional Plus
Fund Share, as  appropriate,  having an aggregate NAV equal to the NAV of his or
her High Yield Fund Shares.  Due to differences  in the market  discounts on the
Funds' shares,  High Yield Fund  stockholders  may,  however,  receive Plus Fund
Shares with an  aggregate  market  value that is higher or lower than the market
value of the shares  previously  held.  The Board  noted  that,  while  Mitchell
Hutchins had no reason to believe that the  Reorganization  would result in High
Yield Fund's  stockholders  receiving shares with a market discount greater than
they would  otherwise  have  experienced,  there could be no assurance  that the
market  discount  to NAV of Plus  Fund  would  not be  greater  than the  market
discount to NAV of High Yield Fund,  or that the market  discount to NAV of Plus
Fund Shares might not be greater in the future.

         Finally,  the Board reviewed the principal  terms of the Plan and noted
that the  securities and other assets held by High Yield Fund at the time of the
Reorganization would be valued at market value, that the Reorganization would be
tax-free to High Yield Fund,  and that High Yield Fund  stockholders  would have
ownership  of a  compatible  fund.  The Board  also  noted  that High Yield Fund
stockholders  would  recognize no gain or loss,  except with respect to any cash
received in lieu of fractional Plus Fund Shares.

         On the  basis of the  information  provided  to each  Board and on each
Board's evaluation of that information,  the Boards determined that the proposed
Reorganization would not dilute the interests of stockholders of either Fund and
that it would be in the best interest of each Fund. Therefore, each Fund's Board
voted  unanimously  to approve  the Plan,  and High  Yield  Fund's  Board  voted
unanimously to recommend that High Yield Fund stockholders approve the Plan.

THE PLAN

         The Plan  provides for the  acquisition  by Plus Fund of all High Yield
Fund's  assets in  exchange  for Plus Fund  Shares  (and cash in lieu of certain
fractional  Plus Fund Shares) and the  assumption by Plus Fund of all High Yield
Fund's  liabilities.  High Yield Fund will then distribute full Plus Fund Shares
to all its  stockholders,  fractional  Plus Fund Shares to  participants in High
Yield Fund's Dividend Reinvestment Plan and cash in lieu of fractional Plus Fund
Shares to all other stockholders.  Each High Yield Fund stockholder will receive
full Plus Fund  Shares  and  either a  fractional  Plus Fund  Share or cash,  as
appropriate,  equal in aggregate NAV to the  aggregate NAV of the  stockholder's
High Yield Fund Shares at the time of the Reorganization. These transactions are
currently  scheduled to occur at 4:00 p.m., Eastern time, on May 26, 2000, or on
such  later  date  as  the  conditions  to  consummate  the  Reorganization  are
satisfied.  High Yield Fund will be liquidated as soon as is  practicable  after
the Closing Date. See "Additional Information About the Reorganization" below.

                                       12

         Each Fund will receive an opinion from  Kirkpatrick & Lockhart LLP, its
counsel,  to the  effect  that the  Reorganization  will  constitute  a tax-free
reorganization  within  the  meaning of section  368(a)(1)(C)  of the Code.  The
opinion will state that neither Fund will recognize any gain or loss for federal
income tax purposes as a result of the  Reorganization  and that High Yield Fund
stockholders  will  recognize  no gain or loss,  except with respect to any cash
received in lieu of fractional  Plus Fund Shares.  To the extent High Yield Fund
sells securities prior to the Closing Date, there may be net recognized gains or
losses to the Fund.  Any net  recognized  gains would increase the amount of any
distribution  made to stockholders of High Yield Fund prior to the Closing Date.

<PAGE>

See  "Additional  Information  About the  Reorganization  -- Federal  Income Tax
Considerations" below.

         If the  Reorganization  is not approved by High Yield Fund stockholders
at the Meeting or the  conditions  of the Plan are not met, High Yield Fund will
continue  to  operate  as a separate  closed-end  fund,  and the Board will then
consider other options and alternatives for the future of the Fund. Either Board
may, in its discretion, terminate the Plan prior to Reorganization.

         REQUIRED   VOTE.   The  proposal  to  approve  the  Plan  requires  the
affirmative vote of a majority of the votes entitled to be cast on the proposal.

      THE BOARD RECOMMENDS THAT YOU VOTE "FOR" THE PLAN OF REORGANIZATION.

                            COMPARISON OF THE FUNDS

FORMS OF ORGANIZATION

         High Yield Fund and Plus Fund are  diversified,  closed-end  management
investment  companies  registered  under the 1940 Act and  organized as Maryland
corporations on June 11, 1993 and April 24, 1998, respectively.  High Yield Fund
commenced  operations on December 7, 1993 and Plus Fund commenced  operations on
June 26, 1998. Both Funds' shares are traded on the NYSE.

         The   operations   of  each  Fund  are  governed  by  its  Articles  of
Incorporation, Bylaws and Maryland law. The overall direction and supervision of
each Fund is the  responsibility  of its Board,  which has the  primary  duty of
ensuring that each Fund adheres to its general investment  policies and programs
and that the Fund is properly administered.

INVESTMENT OBJECTIVES

         The  investment  objectives  of High  Yield  Fund  and  Plus  Fund  are
substantially  similar.  High Yield Fund's investment  objective is high current
income.  The  primary  investment  objective  of Plus Fund is high  income.  Its
secondary  objective is capital  appreciation.  Both Funds seek to achieve their
objective of high income by investing  primarily in a  diversified  portfolio of
lower-rated,  income-producing  debt and related  equity  securities.  Plus Fund
seeks to achieve its secondary objective of capital appreciation by investing in
debt or equity securities that Mitchell Hutchins expects may appreciate in value
as a result of favorable developments affecting the business or prospects of the
issuer, or as a result of declines in long-term interest rates.

                                       13

INVESTMENT POLICIES

         The primary  differences in the investment  policies of High Yield Fund
and Plus Fund are Plus Fund's use of leverage  and its  greater  flexibility  in
choosing the credit quality of its portfolio securities.  Please see "Comparison
of Principal Risk Factors--Primary Differences in Investment Risks of the Funds"
for a  comparison  of the credit  quality of the  securities  in which the Funds
may invest.

         High Yield Fund may invest up to 35% of its net assets in securities of
foreign issuers, including foreign issuers in emerging market countries, with no
more than 10% of its net  assets  in  securities  of  foreign  issuers  that are
denominated and traded in foreign currencies.  Plus Fund may invest up to 35% of
its total assets in securities of foreign issuers,  including foreign issuers in
emerging market countries,  but may not invest more than 15% of its total assets

<PAGE>

in securities  denominated in currencies other than the U.S.  dollar.  Each Fund
may engage in hedging strategies,  such as options, futures and forward currency
contracts,  to attempt to reduce the overall risk of its  investment  portfolio,
enhance income, realize gains or manage its foreign currency exposure. Each Fund
may also use interest  rate swap  transactions  to attempt to reduce the overall
risk of its investment portfolio.

         In selecting  investments for both Funds,  Mitchell  Hutchins relies on
the expertise of the Fund's portfolio manager,  as well as his team of analysts.
The investment process incorporates three key steps: industry selection, company
selection and security selection.  Industry selection consists of an analysis of
economic factors, industry dynamics and yield spreads to determine which sectors
of the market are the most attractive for investment. Company selection combines
Mitchell  Hutchins'  proprietary  financial  forecasting  model with fundamental
credit analysis to determine which companies are the most attractive  investment
candidates.  Mitchell  Hutchins also consults  third party research and conducts
company visits as part of this selection  process.  A security selection process
is done to  determine  the  appropriate  type of security  (such as  lower-rated
bonds,  common stock, etc.). Final security selection depends on relative values
based on a  company's  anticipated  cash  flow,  interest  and  asset  coverage,
leverage and earnings prospects.  Mitchell Hutchins'  portfolio  management team
also uses a disciplined  sell strategy  under which a security will be sold when
the income or total return  potential  declines  relative to its risk level,  or
when the security becomes overvalued when compared to its industry.

INVESTMENT LIMITATIONS

         High Yield Fund generally may not purchase  securities on margin.  Plus
Fund is not restricted in its ability to purchase  securities on margin,  but in
practice it does not do so to any material extent.

         High Yield Fund may not engage in short sales of securities or maintain
a short  position,  except for short sales "against the box" and short positions
in connection with its use of derivative  instruments.  Plus Fund is not limited
in its ability to maintain  short  positions.  However,  neither Fund  currently
engages in short sales.

<PAGE>

LEVERAGE


         Plus  Fund  borrows  money for  investment  purposes.  Such  borrowings
constitute leverage, a speculative technique.  The Fund is authorized to utilize
leverage  in an amount up to 33 1/3 of its total  assets  (including  the amount
obtained through leverage), but its current operating policy which may change at
any time, is to maintain  borrowings in an amount equal to approximately  26-31%
of total assets.  Plus Fund has obtained a secured line of credit under which it
can borrow $200,000,000 for investment  purposes.  (See "Comparison of Principal
Risk Factors - Primary  Differences  in  Investment  Risks of the Funds.") As of
January 31, 2000,  Plus Fund had $167 million in  outstanding  borrowings  under
that line of credit, representing about 31% of its total assets.


         Plus Fund and can also engage in leverage through other bank borrowings
or other transactions involving indebtedness,  through the issuance of preferred
stock, through reverse repurchase transactions or through dollar rolls. However,
the Fund's  ability to use such  other  leverage  is limited by the terms of its
existing line of credit.  Plus Fund will not use leverage if it anticipates that
a leveraged  capital  structure  would result in a lower return to  stockholders
than the Fund could obtain over time without leverage.

                                       14

         Plus Fund can  borrow  additional  money  for  temporary  or  emergency
purposes in an amount not to exceed 5% of its total  assets (not  including  the
amount so borrowed).  By contrast, High Yield Fund can borrow money but only for
temporary or emergency  purposes and only in an amount not  exceeding 10% of its
total assets (not including the amount so borrowed).

PORTFOLIO COMPATIBILITY

         The current portfolio of High Yield Fund,  consisting primarily of debt
securities of issuers located in the United States, is substantially  compatible
with Plus Fund's  portfolio.  It is  anticipated  that none of High Yield Fund's
holdings would need to be sold to accommodate the Reorganization.

FEES AND EXPENSES

         The following table describes the fees and expenses that you may pay if
you buy and  hold  shares  of High  Yield  Fund  and Plus  Fund.  The PRO  FORMA
information  reflects  the  anticipated  effects  of  the  Reorganization.   The

      incurred  0.26%  and  3.46%  for Other  Expenses  and  Total  Annual  Fund
      Operating  Expenses,  respectively,  and the Plus Fund PRO FORMA  Combined

investing in Plus Fund, both before and after the Reorganization, with the costs
of investing in High Yield Fund.

         The example  assumes that you invest $10,000 at net asset value in each
Fund  for the time  periods  indicated.  The  example  also  assumes  that  your
investments  each have a 5% return  each  year and that  each  Fund's  operating
expenses  remain the same.  Although your actual returns and costs may be higher
or lower, based on these assumptions your costs would be:

TRADING HISTORY- SHARE PRICE DATA

         Plus Fund Shres are traded on the NYSE  under the  symbol  "HYF."  High
Yield Fund  Shares are  traded on the NYSE  under the  symbol  "PHT."  Shares of
closed-end  management  investment  companies frequently trade at discounts from
their NAVs, and the Funds' shares have also traded at a discount.  The following
tables  set forth,  in the case of Plus  Fund,  for each  fiscal  quarter  since
inception  and, in the case of High Yield Fund,  for each fiscal  quarter within
the two most recent fiscal years and each fiscal  quarter since the beginning of
the current fiscal year: (a) the per share high and low sales prices as reported
by the NYSE; (b) the NAV per share, based on the Fund's

<PAGE>

computation  as of 4:00  p.m.  on the  last  NYSE  business  day  for  the  week
corresponding  to the dates on which the  respective  high and low  prices  were
recorded; and (c) the discount or premium to NAV represented by the high and low
sales  prices  shown.  The range of NAVs and of premiums and  discounts  for the
shares during the periods  shown may be broader than is shown in this table.  On
March 17, 2000, the  closing  price per share  was $9.25 and $10.25, the NAV per
share was $10.80 and $11.47 and the discount to NAV was  (14.35)% and  (10.64)%,

DIVIDENDS AND OTHER DISTRIBUTIONS

         High   Yield  Fund   distributes   all,   and  Plus  Fund   distributes
substantially all, of its net investment income as monthly dividends.  The Funds
also annually distribute substantially all realized net capital gain (the excess
of net long-term  capital gain over net short-term  capital loss),  realized net
short-term   capital  gain  and   realized  net  gains  from  foreign   currency
transactions, if any. Each Fund may make additional distributions, if necessary,
to avoid a 4% federal excise tax on certain  undistributed  ordinary  income and
capital gains.

         The Funds' monthly dividends may, from time to time,  represent more or
less than the  amount of net investment income earned by the Funds in the period

<PAGE>

to which the  dividend  relates.  Undistributed  net  investment  income will be
available  to  supplement  future  dividends,  which might  otherwise  have been
reduced  by reason  of a  decrease  in the  Funds'  monthly  net  income  due to
fluctuations or expenses.  Undistributed  net investment  income is reflected in
the Funds' NAV and,  accordingly,  a Fund's NAV is reduced  when  dividends  are
paid.  The dividend  rate on each Fund's shares is adjusted from time to time by
that Fund's Board of Directors and varies as a result of the Fund's performance.

                                       16

DIVIDEND REINVESTMENT PLANS

         High Yield Fund and Plus Fund have  established  Dividend  Reinvestment
Plans ("Reinvestment  Plans") under which all stockholders whose Fund shares are
registered  in  their  own  names,  or in the name of  PaineWebber  Incorporated
("PaineWebber")  or its nominee,  have all dividends and other  distributions on
their shares automatically reinvested in additional shares of the relevant Fund,
unless such  stockholders  elect to receive cash.  Stockholders in each Fund may
affirmatively  elect to receive all  dividends and other  distributions  in cash
paid by check mailed  directly to them by that Fund's  Transfer  Agent (which in
each  case is PNC Bank,  National  Association,  acting  through  PFPC  Inc.) as
dividend  disbursing agent.  Stockholders who hold their shares in the name of a
broker or nominee other than  PaineWebber  (or its nominee)  should contact such
broker or other nominee to determine  whether,  or how, they may  participate in
the Reinvestment  Plans. The ability of such  stockholders to participate in the
Reinvestment  Plans  may  change  if their  shares  of the  respective  Fund are
transferred into the name of another broker or nominee.

         The  Transfer  Agent  for each Fund  serves  as agent  for that  Fund's
stockholders in administering  the Reinvestment  Plans.  After a Fund declares a
dividend or determines to make another distribution, the Transfer Agent receives
the cash payment as agent for the participants. However, the basis on which each
Fund's Transfer Agent acquires Fund shares under the Reinvestment Plan differs.

         High Yield Fund's  Transfer  Agent uses the cash that it receives  from
dividends paid by the Fund to buy Fund shares in the open market, on the NYSE or
otherwise,  for the  participants'  accounts.  Such shares may be  purchased  at
prices  that may be  higher  or lower  than the NAV per share of the Fund at the
time of purchase.  The number of shares  purchased with each  distribution for a
particular  stockholder equals the result obtained by dividing the amount of the
distribution  payable  to  that  stockholder  by the  average  price  per  share
(including applicable brokerage commissions) that the Transfer Agent was able to
obtain in the open  market.  High  Yield  Fund does not issue any new  shares in
connection with its Reinvestment Plan.

         Plus  Fund's  Transfer  Agent  uses  the  cash  that it  receives  from
dividends  paid by the Fund to  acquire  shares for the  participants'  accounts
differently,  depending  upon the  circumstances  described  below.  It acquires
shares  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 NAV per share is equal to or less than the  market
price per share plus  estimated  brokerage  commissions  (such  condition  being
referred to as "market premium"), the Transfer Agent invests the dividend amount
on behalf of the participants in newly issued shares. The number of newly issued
shares to be credited to each  participant's  account is  determined by dividing
the  dollar  amount of the  dividend  by the NAV per share (but in no event less
than 95% of the then-current  market price per share) on the date the shares are
issued.  If, on the dividend payment date, the NAV per share is greater than the
market value per share (such condition being referred to as "market  discount"),
the Transfer Agent invests the dividend amount on behalf of the  participants in
shares  acquired in  open-market  purchases.  The number of  outstanding  shares
purchased  with  each   purchased  with  each   distribution  for  a  particular

<PAGE>

stockholder   equals  the  result   obtained  by  dividing  the  amount  of  the
distribution  payable  to  that  stockholder  by the  average  price  per  share
(including applicable brokerage  commissions) that the Transfer Agent is able to
obtain in the open market.

         For Plus Fund,  if there is a market  discount on the dividend  payment
date, the Transfer Agent has 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 ("last  purchase  date"),  to invest the
dividend  amount in shares  acquired in open-market  purchases.  Since Plus Fund
pays monthly income dividends, the period during which open-market purchases can
be made  exists  only from the  payment  date of the  dividend  through the date
before the next "ex-dividend" date.  Typically,  this is approximately ten days.
If,  before the Transfer  Agent has  completed its  open-market  purchases,  the
market  price of a share  exceeds  the NAV per  share,  the  average  per  share
purchase  price  paid  by  the  Transfer  Agent  (were  it  to  continue  making
open-market  purchases) might exceed the Fund's NAV per share. This would result
in the  acquisition  of fewer shares than if the dividend had been paid in newly
issued  shares  on  the  dividend   payment  date.   Accordingly,   Plus  Fund's
Reinvestment  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 earlier
of the close of business on the last  purchase  date or the first day during the
purchase  period on which the NAV per  share  equals or is less than the  market
price per share.

                                       17

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

         Each Fund's Transfer Agent  maintains all  stockholder  accounts in its
Reinvestment  Plans and furnishes  written  confirmations of all transactions in
the accounts,  including information needed by stockholders for personal and tax
records.  Shares  in the  account  of each  Reinvestment  Plan  participant  are
maintained  by the  Transfer  Agent  in  uncertificated  form in the name of the
participant.  Each High Yield Fund stockholder's proxy will reflect those shares
of stock purchased pursuant to its Reinvestment Plan.

         There is no charge to participants  for reinvesting  dividends or other
distributions.  The Transfer  Agents' fees for the handling of  reinvestment  of
distributions are paid by the respective Funds. However, each participant pays a
PRO RATA share of brokerage  commissions  incurred  with respect to the Transfer
Agents' open market purchases of Fund shares in connection with the reinvestment
of distributions.

<PAGE>

         The automatic reinvestment of dividends and other distributions in Fund
shares  does not relieve  participants  of any income tax that may be payable on
such distributions.

         A stockholder who has elected to participate in a Reinvestment Plan may
terminate  participation in the  Reinvestment  Plan at any time without penalty,
and stockholders who have previously terminated  participation in a Reinvestment
Plan may rejoin it at any time.  Changes in elections must be made in writing to
the Transfer Agent and should include the stockholder's name and address as they
appear on the share certificate or in the Transfer Agent's records.  An election
to terminate participation in a Reinvestment Plan is deemed to be an election by
a stockholder to take all subsequent  distributions  in cash until such election
is changed. An election will be effective only for dividends declared and having
a record  date at least  ten days  after  the  date on  which  the  election  is
received.

         Each Fund has reserved the right to amend or terminate its Reinvestment
Plan  with  respect  to  any  dividend  if  notice  of the  change  is  sent  to
participants  at least 30 days  before the record  date for such  dividend.  The
Reinvestment Plans also may be amended or terminated by the Transfer Agent by at
least 30 days' written notice to all participants. All correspondence concerning
the  Reinvestment  Plans should be directed to the  appropriate  Fund's Transfer
Agent at PNC Bank,  National  Association,  c/o PFPC Inc., 400 Bellevue Parkway,
Wilmington, Delaware 19809.

MANAGEMENT OF THE FUNDS

         The  overall  management  of the  business  and affairs of each Fund is
vested  with  its  Board of  Directors.  Each  Board  approves  all  significant
agreements  between  the  relevant  Fund and  persons  or  companies  furnishing
services to it, including the Fund's agreements with its investment  adviser and
administrator,   custodian  and  transfer  and  dividend  disbursing  agent  and
registrar.  The day-to-day operations of each Fund are delegated to its officers
and to  Mitchell  Hutchins,  subject to such  Fund's  investment  objective  and
policies and to general supervision by its Board of Directors.

         Subject to the  supervision  of each Fund's  Board,  Mitchell  Hutchins
provides investment  advisory and administration  services to each Fund pursuant
to separate Investment Advisory and Administration  Contracts dated November 23,
1993 for High Yield Fund and June 22, 1998 for Plus Fund ("Advisory Contracts").
Pursuant to each  Advisory  Contract,  Mitchell  Hutchins  provides a continuous
investment program for the relevant Fund, makes investment  decisions and places
orders  to buy,  sell or hold  particular  securities.  Mitchell  Hutchins  also
supervises all matters  relating to the operation of the Fund and obtains for it
corporate officers, clerical staff, office space, equipment and services.

         The portfolio manager responsible for the day-to-day management of both
Funds is James F.  Keegan,  a senior vice  president of Mitchell  Hutchins.  Mr.
Keegan has been employed by Mitchell  Hutchins since March 1996 and has been the
Funds'  portfolio  manager  since  February  2000.  Prior to March 1996,  he was
director of fixed  income  strategy and research of Merrion  Group,  L.P.  Other
members of the  Mitchell  Hutchins  High Income  Group  provide  input on market
outlook,  interest rate forecasts,  and other considerations  pertaining to high
yield, high risk income securities.

<PAGE>

         High   Yield   Fund  and  Plus  Fund  pay   investment   advisory   and
administrative  fees at  different  rates,  and  they  calculate  their  fees in
different ways. High Yield Fund pays Mitchell Hutchins  investment  advisory and
administration  fees,  computed weekly and paid monthly, of 0.90% of its average
weekly net assets.  Plus Fund pays Mitchell  Hutchins fees,  computed weekly and
paid monthly, of 0.70% of its Managed Assets. Because the fees are calculated as
a  percentage  of Managed  Assets,  and given the level of Plus  Fund's  current
borrowings  and its  expectation  to maintain  borrowings  in an amount equal to
approximately  26-31%  of its  total  assets,  it is  likely  that  Plus  Fund's
effective  investment  advisory  and  administration  fee rate will  continue to
exceed 0.90% of its net assets.

         Each Fund also incurs various other expenses in its operations, such as
custody and transfer  agency fees,  brokerage  commissions,  professional  fees,
expenses  of Board and  stockholder  meetings,  fees and  expenses  relating  to
registration  of each  Fund's  shares,  taxes and  governmental  fees,  fees and
expenses of the Directors,  costs of obtaining  insurance,  expenses of printing
and   distributing   stockholder   materials,    organizational   expenses   and
extraordinary  expenses,  including costs or losses in any  litigation.  For the
fiscal  years ended July 31, 1999,  July 31, 1998 and July 31, 1997,  High Yield
Fund's total expenses, stated as a percentage of average net assets, were 1.19%,
1.15% and 1.34%,  respectively.  For the fiscal period June 26, 1998 through May
31, 1999,  Plus Fund's  total  expenses,  stated as a percentage  of average net
assets,  were 3.02%.  This figure  includes  1.87%  related to interest  expense
representing the cost of Plus Fund's leverage.

         In accordance with procedures  adopted by each Fund's Board,  brokerage
transactions  for  each  Fund  may  be  conducted  through  PaineWebber  or  its
affiliates,  and each Fund pays fees to PaineWebber  for its services as lending
agent in such Fund's portfolio  securities  lending program.

         The Funds have the same Directors and officers.  Upon completion of the
Reorganization,  the  Directors  and officers of Plus Fund will  continue as the
Directors  and  officers for the  combined  Fund.  Please see Appendix B for the
names,  ages and principal  occupations of the current directors and officers of
both Funds.

OTHER SERVICE PROVIDERS

         State Street Bank and Trust Company,  One Heritage Drive, North Quincy,
Massachusetts  02171,  serves as custodian of both Funds'  assets.  State Street
Bank and Trust Company employs foreign  sub-custodians,  approved by each Fund's
Board of Directors,  in accordance with applicable  requirements  under the 1940
Act,  to provide  custody of each  Fund's  foreign  assets.  PNC Bank,  National
Association,  acting  through  PFPC,  whose  principal  business  address is 400
Bellevue  Parkway,  Wilmington,  Delaware  19809,  is each Fund's  transfer  and
dividend  disbursing  agent  and  registrar.   The  Funds  also  have  the  same
independent auditor,  Ernst & Young LLP, which is located at 787 Seventh Avenue,
New York, New York 10019. Upon completion of the Reorganization,  these entities
will continue to provide services to the combined Fund.


CALCULATION OF NET ASSET VALUE

         The net asset value of High Yield Fund's shares is determined weekly as
of the close of regular trading on the NYSE on the last day of the week on which
the NYSE is open for  trading.  The net  asset  value of Plus  Fund's  shares is
determined as of the close of regular  trading on the NYSE on each Business Day,
which  is  defined  as each  Monday  through  Friday  when  the NYSE is open for
trading. The net asset value of both Funds' shares also is determined monthly at
the close of  regular  trading on the NYSE on the last day of the month on which
the NYSE is open for trading.  Each Fund's net asset value per share is computed
by dividing the value of the securities  held by the Fund plus any cash or other
assets (including  interest and dividends accrued but not yet receivd and earned
discount) minus all liabilities (including accrued expenses) by the total number
of shares outstanding at such time.

                 ADDITIONAL INFORMATION ABOUT THE REORGANIZATION

TERMS OF THE REORGANIZATION

         The  terms  and  conditions  under  which  the  Reorganization  may  be
consummated  are set forth in the Plan.  Significant  provisions of the Plan are

<PAGE>

summarized  below;  however,  this  summary  is  qualified  in its  entirety  by
reference  to the Plan,  a copy of which is attached as Appendix A to this Proxy
Statement/Prospectus.

         The Plan contemplates (a) Plus Fund's acquiring on the Closing Date all
the assets of High Yield Fund in exchange  solely for Plus Fund Shares (and cash
in lieu of certain  fractional  Plus Fund Shares) and Plus Fund's  assumption of
all High Yield Fund's  liabilities and (b) the  distribution of those shares and
cash to High Yield Fund stockholders. High Yield Fund's assets include all cash,
cash  equivalents,  securities,  receivables  (including  interest and dividends
receivable),  claims and  rights of  action,  rights to  register  shares  under
applicable  securities  laws,  books and records,  deferred and prepaid expenses
shown as assets on its books and other  property  owned by it as of the close of
business on the Closing Date ("Effective Time") (collectively,  "Assets").  Plus
Fund will assume from High Yield Fund all its  liabilities,  debts,  obligations
and duties of whatever kind or nature, whether absolute,  accrued, contingent or
otherwise, whether or not arising in the ordinary course of business, whether or
not  determinable  at the  Effective  Time and whether or not referred to in the
Plan (collectively, the "Liabilities");  provided, however, that High Yield Fund
will use its best efforts to discharge all of its known Liabilities prior to the
Effective  Time.  Plus Fund will deliver its shares (and cash in lieu of certain
fractional  Plus Fund Shares) to High Yield Fund,  which then will distribute to
High Yield Fund stockholders.

         The value of the Assets, the amount of the Liabilities and the NAV of a
Plus Fund Share  will be  determined  by  Mitchell  Hutchins  as of the close of
regular trading on the NYSE on the Closing Date.  Portfolio  securities normally
will be valued based on market values obtained from independent pricing services
that use reported last sales  prices,  current  market  quotations or valuations
from  computerized  "matrix"  systems  that derive  values  based on  comparable
securities.  If a market  value is not  available  from an  independent  pricing
source for a particular  security,  that security will be valued at a fair value
determined by or under the direction of the Funds'  Boards.  The amortized  cost
method  generally  will be used to value  bonds  that will  mature in 60 days or
less.

         On, or as soon as practicable  after, the Closing Date, High Yield Fund
will distribute to its  stockholders of record as of the Effective Time the Plus
Fund Shares and cash it receives so that each High Yield Fund  stockholder  will
receive full Plus Fund Shares and cash or a fractional  share,  as  appropriate,
equal in aggregate NAV to the aggregate NAV of the stockholder's High Yield Fund
shares.  That distribution will be accomplished by opening accounts on the books
of Plus Fund in the names of High Yield Fund's  stockholders and crediting those
accounts with full Plus Fund Shares and cash or a fractional Plus Fund Share, as
appropriate, to which each stockholder is entitled.

         Immediately after the  Reorganization,  each former stockholder of High
Yield  Fund will own full Plus Fund  Shares and cash or a  fractional  Plus Fund
Share,  as  appropriate,  equal in aggregate  NAV to the  aggregate  NAV of that
stockholder's  High Yield Fund Shares  immediately prior to the  Reorganization.
The  NAV  per  share  of  Plus  Fund  will  not   change  as  a  result  of  the
Reorganization.  Thus, the  Reorganization  will not result in a dilution of any
stockholder ownership interest.

<PAGE>

DESCRIPTION OF SECURITIES TO BE ISSUED

         Pursuant to its  Articles of  Incorporation  and Bylaws,  Plus Fund may
issue up to  200,000,000  shares of capital stock,  $0.001 par value,  having an
aggregate par value of $200,000.

         Each share of Plus Fund represents an equal proportionate interest with
other  shares in that Fund.  Each share has equal voting  privileges,  except as
noted in Plus Fund's SAI, and each share is equally  entitled to  dividends  and
other  distributions  out of the income  earned and gain  realized on the assets
belonging to the Fund as declared by the Board.  Plus Fund Shares  entitle their
holders to one vote per full share and fractional  votes for  fractional  shares
held. Plus Fund Shares are fully paid and non-assessable when issued.

                                       22

DIVIDENDS AND OTHER DISTRIBUTIONS

         On or before the Closing Date,  High Yield Fund will declare and pay as
a distribution substantially all of its undistributed net investment income, net
capital gain,  net short-term  capital gain and net gains from foreign  currency
transactions to maintain its tax treatment as a RIC.

         The  consummation  of the  Reorganization  is  subject  to a number  of
conditions set forth in the Plan, some of which may be waived by either Fund. In
addition,  the Plan may be amended in any mutually agreeable manner, except that
no amendment  may be made  subsequent  to the Meeting that would have a material
adverse effect on High Yield Fund stockholders' interests.

SURRENDER AND EXCHANGE OF HIGH YIELD FUND STOCK CERTIFICATES

         After the Effective Time, each holder of an outstanding  certificate(s)
formerly  representing High Yield Fund Shares will be entitled to receive,  upon
surrender of his or her certificate(s), a certificate representing the number of
Plus Fund Shares  distributable  with  respect to the  holder's  High Yield Fund
Shares.  PLEASE DO NOT SEND IN ANY SHARE  CERTIFICATES  AT THIS  TIME.  Promptly
after the  Effective  Time,  the  Transfer  Agent  will  mail to each  holder of
certificate(s) formerly representing High Yield Fund Shares,  instructions and a
letter  of  transmittal  for  use in  surrendering  those  certificate(s)  for a
certificate representing Plus Fund Shares.

         From and after the Effective Time,  certificates  formerly representing
High Yield Fund Shares will be deemed for all purposes to evidence  ownership of
the number of full Plus Fund  Shares and either  fractional  Plus Fund Shares or
rights  to cash in lieu  thereof,  as  applicable,  distributable  with  respect
thereto in the Reorganization,  provided that until a holder of such certificate
surrenders it, no dividends payable to the holders of record of Plus Fund Shares
as of any date  subsequent to the  Effective  Time shall be paid to that holder.
Any such  dividends  will be paid to that holder,  without  interest,  when that
holder surrenders those High Yield Fund Share certificate(s) for exchange.

         From and after the  Effective  Time,  there will be no transfers on the
stock  transfer  books  of High  Yield  Fund.  If,  after  the  Effective  Time,
certificates  representing  High Yield Fund Shares are  presented  to Plus Fund,
they will be canceled and  exchanged  for  certificates  representing  Plus Fund
Shares.


<PAGE>

ACCOUNTING TREATMENT

         The Reorganization  will be accounted for on a tax-free combined basis.
Accordingly, the book cost basis to Plus Fund of the Assets transferred to it by
High  Yield Fund will be the same as High  Yield  Fund's  book cost basis of the
Assets.

FEDERAL INCOME TAX CONSIDERATIONS

         Each Fund will receive an opinion from Kirkpatrick & Lockhart  LLP, its
counsel, substantially to the following effect:

         (1) Plus Fund's  acquisition of the Assets in exchange  solely for full
         and  fractional  Plus  Fund  Shares  (plus  cash  in  lieu  of  certain
         fractional  Plus  Fund  Shares)  and  Plus  Fund's  assumption  of  the
         Liabilities,  followed by High Yield Fund's  distribution of those full
         Plus Fund  Shares PRO RATA to all its  stockholders,  those  fractional
         Plus Fund Shares PRO RATA to its  stockholders  that participate in the
         Dividend  Reinvestment  Plan,  and  that  cash  PRO  RATA to its  other
         stockholders,  constructively  in  exchange  for their  High Yield Fund
         Shares, will qualify as a reorganization  within the meaning of section
         368(a)(1)(C)  of  the  Code,  and  each  Fund  will  be "a  party  to a
         reorganization" within the meaning of section 368(b) of the Code;

         (2) High Yield Fund will  recognize  no gain or loss on its transfer of
         the Assets to Plus Fund in  exchange  solely  for Plus Fund  Shares and
         cash in lieu of  certain  fractional Plus Fund  Shares and Plus  Fund's
         assumption of the  Liabilities  or on the  subsequent  distribution  of
         those shares and cash to High Yield Fund's stockholders in constructive
         exchange for their High Yield Fund Shares;

                                       23

         (3) Plus  Fund will  recognize  no gain or loss on its  receipt  of the
         Assets in exchange  solely for Plus Fund  Shares  (plus cash in lieu of
         certain  fractional  Plus  Fund  Shares)  and  its  assumption  of  the
         Liabilities;

         (4) Plus  Fund's  basis for the  Assets  will be the same as High Yield
         Fund's basis therefor  immediately before the Reorganization,  and Plus
         Fund's  holding  period for the Assets will  include  High Yield Fund's
         holding period therefor;

         (5) A High Yield Fund stockholder will recognize no gain or loss on the
         constructive  exchange of all the stockholder's  High Yield Fund Shares
         solely for Plus Fund Shares, and cash in lieu of a fractional Plus Fund
         Share, where appropriate,  pursuant to the Reorganization,  except with
         respect to that cash; and

         (6) A High Yield Fund  stockholder's  aggregate basis for the Plus Fund
         Shares to be received by it in the  Reorganization  will be the same as
         the aggregate basis for its High Yield Fund Shares to be constructively
         surrendered  in exchange for those Plus Fund  Shares,  decreased by any
         cash received,  and increased by any gain recognized,  on the exchange.
         Its holding  period for those Plus Fund Shares will include its holding
         period for those High Yield Fund Shares,  provided the stockholder held
         them as capital assets on the Closing Date.

         The opinion may state that no opinion is  expressed as to the effect of
the  Reorganization on the Funds or any High Yield Fund stockholder with respect
to any  Asset  as to  which  any  unrealized  gain  or loss  is  required  to be
recognized  for federal  income tax purposes at the end of a taxable year (or on
the  termination  or  transfer   thereof)  under  a  mark-to-market   system  of
accounting.

         Utilization   by   Plus   Fund   after   the   Reorganization   of  any
pre-Reorganization  capital losses  realized by High Yield Fund could be subject
to limitation in future years under the Code.


<PAGE>

         Stockholders  of High  Yield Fund  should  consult  their tax  advisers
regarding the effect, if any, of the Reorganization in light of their individual
circumstances.  Because the  foregoing  discussion  only  relates to the federal
income tax consequences of the  Reorganization,  those  stockholders also should
consult  their tax advisers as to state and local tax  consequences,  if any, of
the Reorganization.

                     ADDITIONAL INFORMATION ABOUT BOTH FUNDS

PORTFOLIO SECURITIES

         The following  summarizes some of the  characteristics of securities in
which the Funds may invest. See the SAI for more information.

         DEBT OBLIGATIONS; LOWER-RATED SECURITIES. The lower-rated securities in
which the Funds may invest are debt  obligations,  including bonds,  debentures,
notes, corporate loans and similar instruments and securities, and are generally
unsecured.  Mortgage and asset-backed  securities are types of debt obligations,
and  income-producing,  non-convertible  preferred stocks may be treated as debt
obligations for the Funds'  investment  purposes.  Debt  obligations are used by
private and public issuers to borrow money from  investors.  The issuer pays the
investor a fixed or variable rate of interest and normally must repay the amount
borrowed on or before maturity.  Debt obligations are subject to varying degrees
of risk of loss,  and the  prices  (I.E.,  market  values)  of debt  obligations
fluctuate to varying degrees in response to changes in market interest rates.

         Investments  in  lower-rated  securities  (junk bonds) are subject to a
greater  price  volatility  and  a  greater  risk  of  loss  than   higher-rated
investments  and  are  considered  by  Rating   Agencies  to  be   predominantly
speculative,  with limited  protection of interest and principal  payments.  The
lower-rated securities in which the Funds may invest include securities that are
in  default  or that  face the risk of  default  with  respect  to  payments  of
principal or interest.  Lower-rated  securities generally offer a higher current
yield  than  that  available  from  higher-rated  issues.  However,  lower-rated
securities  are subject to higher risks in that they are  especially  subject to
adverse  changes in general  economic  conditions and in the industries in which
the issuers are engaged,  to changes in the  financial  condition of the issuers
and to negative  publicity or investor  perceptions.  During periods of economic
downturn, issuers of lower-rated income securities,  especially highly leveraged
issuers,  may  experience  financial  stress that could  adversely  affect their
ability to make payments of principal and interest and increase the  possibility
of default.  In addition,  such issuers may not have more traditional methods of
financing available to them, and they may be unable to repay debt at maturity by
refinancing.  The risk of loss due to  payment  defaults  by  these  issuers  is
significantly  greater because lower-rated  securities  frequently are unsecured
and subordinated to the prior payment of senior indebtedness.

         In order for a Fund to enforce  its rights in the event of a default on
lower-rated  securities,  the Fund may be  required  to take  possession  of and
manage  collateral  securing  the  issuer's  obligations.  This may increase the
Fund's  operating  expenses and adversely affect the Fund's net asset value. The
Funds may also be limited in their ability to enforce their rights and may incur
greater  costs in  enforcing  their  rights in the event an issuer  becomes  the
subject of  bankruptcy  proceedings.  In addition,  the Funds may be required to
participate in a restructuring of the obligation.

         The Funds are also subject to  significant  uncertainty  as to when, in
what  manner and for what  value the  obligations  evidenced  by  securities  of
bankrupt  issuers will eventually be satisfied  (e.g.,  through a liquidation of
the obligor's  assets,  an exchange  offer or plan of  reorganization  involving
these securities or a payment of some amount in satisfaction of the obligation).
If the  Funds  participate  in  negotiations  of any  exchange  offer or plan of
reorganization with respect to the issuer of these securities,  the Funds may be
restricted  from disposing of the  securities  that they hold until the exchange
offer or reorganization of the bankrupt issuer is completed.  In addition,  even
if an  exchange  offer is made or plan of  reorganization  is adopted  for these
bankrupt issuers,  securities or other assets received by the Funds as a part of
an  exchange  offer or plan of  reorganization  may have a lower value or income
potential than may have been anticipated when the investment was made. Moreover,
any  securities  that the Funds receive upon  completion of an exchange offer or
plan of reorganization may be restricted as to resale.

         Some or all of the  securities  in which the Funds may invest may, when
purchased,  be  illiquid or may  subsequently  become  illiquid.  In many cases,
lower-rated  income  securities  may be  purchased  in private  placements  and,
accordingly,  will be subject to  restrictions on resale as a matter of contract
or under the  securities  laws.  It may be more  difficult to determine the fair
value  of  such  securities  for  purposes  of  computing  a  Fund's  NAV.  Like


<PAGE>

higher-rated  income  securities,  lower-rated  income securities  generally are
purchased  and sold  through  dealers who make a market in such  securities  for
their own accounts.  However,  there are fewer dealers in the lower-rated income
securities  market,  and that  market  may be less  liquid  than the  market for
higher-rated  income  securities,  even under normal economic  conditions.  As a
result,  during periods of high demand in the lower-rated  securities market, it
may be difficult to acquire  lower-rated  securities  that are  appropriate  for
investment by the Funds.  Adverse economic  conditions and investor  perceptions
thereof  (whether or not based on economic  reality) may impair liquidity in the
lower-rated  securities  market and may cause the prices that the Funds  receive
for its lower-rated income securities to be reduced. In addition,  the Funds may
experience  difficulty  in  liquidating  a  portion  of  their  portfolios  when
necessary  to meet the  Funds'  liquidity  needs or in  response  to a  specific
economic event,  such as deterioration in the  creditworthiness  of the issuers.
Under such  conditions,  judgment may play a greater role in valuing  certain of
the Funds' portfolio  instruments  than in the case of instruments  trading in a
more liquid market.

                                       26

         CORPORATE  LOANS.  The Funds may invest in loans  extended to corporate
borrowers  by  commercial  banks and other  financial  institutions  ("Corporate
Loans").  As in the case of other lower-rated  securities,  such Corporate Loans
can be expected to provide higher yields than lower-yielding, higher-rated fixed
income securities,  but they may be subject to greater risk of loss of principal
and interest. There are, however, some significant differences between Corporate
Loans  and  other  lower-rated   securities.   Corporate  Loan  obligations  are
frequently  secured by  collateral  pledged by the  borrower,  and  investors in
Corporate Loans frequently  benefit from debt service  subordination  provisions
imposed on the borrower's  bondholders.  These arrangements are designed to give
Corporate  Loan investors  preferential  treatment (at least with respect to the
collateral) over other creditors of the borrower in the event of its insolvency.
Even when these arrangements exist, however,  there can be no assurance that the
principal  and interest  owed on the  Corporate  Loans will be repaid in full or
that the holders of such Corporate Loans will not experience delays in receiving
payment.  Corporate Loans generally bear interest at variable rates that are set
at a specified  "spread" above a base lending rate,  such as the prime rate of a
U.S. bank,  which may fluctuate on a day-to-day  basis,  or above an established
index, such as the London Interbank Offered Rate ("LIBOR"), which is adjusted at
set  intervals  (typically  30 days,  but  generally  not more  than one  year).
Consequently,  the value of Corporate Loans held by the Funds may be expected to
fluctuate  less in  response  to  changes  in market  interest  rates than would
fixed-rate securities.  However, the secondary market for Corporate Loans is not
as well developed as the secondary market for other lower-rated securities,  and
reliable  valuation  information  about Corporate Loans may be harder to obtain.
Therefore,  a Fund may have  difficulty  liquidating  and valuing the  Corporate
Loans that it holds.

         Generally,  Corporate Loans are originated  through a lending syndicate
in which a bank acts as an  administrative  agent on behalf of the other lenders
to negotiate the loan terms and assumes certain loan servicing responsibilities.
The Funds' investments in Corporate Loans normally are through assignments of or
participations  in all or a portion of another lender's  interest in a Corporate
Loan.  Participations  typically  result  in  the  Funds  having  a  contractual
relationship  only with the lender,  not with the borrower.  In a participation,
the Funds are entitled to receive agreed-upon portions of payments of principal,
interest  and any loan fees by the lender  only when and if those  payments  are
received.  Also,  the  Funds  might not  directly  benefit  from any  collateral
supporting the Corporate Loan. As a result,  the Funds assume the credit risk of
both the  borrower  and the lender  that sold the  participation.  If the lender
becomes  insolvent,  the Funds  might be  treated as a general  creditor  of the
lender  and might not  benefit  from any  set-off  between  the  lender  and the
borrower. In an assignment,  the Funds are entitled to receive payments directly
from the borrower and, therefore,  do not depend on the assigning lender to pass
those payments on to the Funds.  However,  in an assignment,  the Funds may have
greater  direct  responsibilities  with respect to  collection  of principal and
interest and the enforcement of its rights.

         EQUITY  SECURITIES.  High  Yield  Fund may  acquire  equity  securities
(including  common stocks,  rights and warrants for equity and debt  securities)
only when they are attached to debt  securities  or as part of a unit  including
debt  securities,  or in  connection  with a  conversion  or  exchange  of  debt
securities. Plus Fund may invest in these equity securities as well as in equity
securities of lower-rated or comparable  issuers  (issuers whose debt securities
are  lower-rated  or  who  Mitchell  Hutchins  determines  to be  of  comparable
quality).  These equity  securities may include common and preferred  stocks and
securities  that are  convertible  into them,  including  common stock  purchase
warrants and rights, equity interests in trusts, partnerships, joint ventures or
similar  enterprises  and  depository  receipts.   Common  stocks  represent  an
ownership  interest  in a  company.  Preferred  stock has  certain  fixed-income
features, like debt securities,  but is actually equity in a company. The prices
of equity securities  generally  fluctuate more than debt securities and reflect
changes in a company's  financial  condition and in overall  market and economic
conditions.  Common  stocks  generally  represent  the riskiest  investment in a
company.

                                       27
<PAGE>

         Warrants are securities permitting, but not obligating, their holder to
subscribe  for other  securities.  Warrants  do not carry with them the right to
dividends  or voting  rights with  respect to the  securities  that they entitle
their holder to purchase,  and they do not represent any rights in the assets of
the issuer.  As a result,  warrants  may be  considered  more  speculative  than
certain other types of investments. In addition, the value of a warrant does not
necessarily  change with the value of the  underlying  securities  and a warrant
ceases to have value if it is not exercised prior to its expiration date.

OTHER INVESTMENT PRACTICES

         The Funds may engage in the  following  investment  practices,  each of
which may involve certain risks.

         LENDING OF PORTFOLIO SECURITIES.  Each Fund is authorized to lend up to
33 1/3% of its total assets to  broker-dealers  or institutional  investors that
Mitchell Hutchins deems qualified.  Lending securities enables the Funds to earn
additional  income,  but  could  result in a loss or delay in  recovering  these
securities.  The  borrower  of  a  Fund's  portfolio  securities  must  maintain
acceptable  collateral with the Fund's custodian in an amount,  marked to market
daily, at least equal to the market value of the securities loaned, plus accrued
interest  and  dividends.   Acceptable  collateral  is  limited  to  cash,  U.S.
government  securities  and  irrevocable  letters  of credit  that meet  certain
guidelines  established  by Mitchell  Hutchins.  Each Fund may reinvest any cash
collateral in money market  investments or other short-term liquid  investments,
including other investment  companies.  A Fund also may reinvest cash collateral
in private  investment  vehicles  similar to money market  funds,  including one
managed by Mitchell  Hutchins.  In determining  whether to lend  securities to a
particular  broker-dealer  or  institutional  investor,  Mitchell  Hutchins will
consider, and during the period of the loan will monitor, all relevant facts and
circumstances,  including the  creditworthiness of the borrower.  Each Fund will
retain  authority to terminate  any of its loans at any time.  Each Fund may pay
reasonable  fees in connection with a loan and may pay the borrower or a placing
broker a negotiated  portion of the interest earned on the  reinvestment of cash
held as  collateral.  A Fund will receive  amounts  equivalent to any dividends,
interest or other  distributions on the securities loaned. Each Fund will regain
record ownership of loaned  securities to exercise  beneficial  rights,  such as
voting and subscription  rights,  when regaining such rights is considered to be
in the Fund's interest.

         Pursuant  to  procedures  adopted by the Boards  governing  each Fund's
securities  lending  program,  PaineWebber has been retained to serve as lending
agent for each  Fund.  The  Boards  have also  authorized  the  payment  of fees
(including  fees  calculated as a  percentage of invested  cash  collateral)  to
PaineWebber for these services.  Each Board  periodically  reviews the portfolio
securities  loan  transactions  for which  PaineWebber  acts as  lending  agent.
PaineWebber  also has been approved as a borrower  under each Fund's  securities
lending program.

         WHEN-ISSUED  AND DELAYED  DELIVERY  SECURITIES.  Each Fund may purchase
debt securities on a "when-issued" basis or may purchase or sell debt securities
on a "delayed  delivery" basis, i.e., for issuance or delivery to the Fund later
than the normal settlement date for such securities at a stated price and yield.
The Funds generally do not pay for such securities or start earning  interest on
them until they are received.  However,  when a Fund undertakes a when-issued or
delayed  delivery  obligation,  it  immediately  assumes the risks of ownership,
including  the  risk  of  price  fluctuation.  When a Fund  agrees  to  purchase
securities on a when-issued or delayed  delivery basis, its custodian sets aside
in a segregated account, cash or liquid securities,  marked-to-market  daily, in
an amount at least equal to the amount of the commitment.  Failure of the issuer
to deliver a security  purchased by a Fund on a when-issued or delayed  delivery
basis may result in the Fund's  incurring  a loss or missing an  opportunity  to
make an alternative investment. Depending on market conditions, a  Fund's  when-

<PAGE>

issued and delayed delivery  purchase  commitments could cause its NAV per share
to be more  volatile,  because such  securities may increase the amount by which
the Fund's total assets, including the value of when-issued and delayed delivery
securities held by the Fund, exceed its net assets.

                                       28

         FORWARD   COMMITMENTS.   Each  Fund  may  make  contracts  to  purchase
securities  for a fixed price at a future date beyond the  customary  settlement
time ("forward  commitments")  without its doing so being considered leverage if
it holds, and maintains until the settlement date in a segregated account,  cash
or liquid  securities in an amount  sufficient to meet the purchase price, or if
it enters into  offsetting  contracts  for the forward sale of other  securities
that it owns.  Forward  commitments  involve  a risk of loss if the value of the
security to be purchased  declines prior to the settlement date. This risk is in
addition to the risk of decline in value of the Fund's other assets.  Where such
purchases  are made through  dealers,  a Fund relies on the dealer to consummate
the sale. The dealer's failure to do so may result in the loss to the Fund of an
advantageous  yield or price.  Although a Fund will generally enter into forward
commitments with the intention of acquiring portfolio securities,  each Fund may
dispose of a  commitment  prior to  settlement  if  Mitchell  Hutchins  deems it
appropriate to do so. Each Fund may realize  short-term  capital gains or losses
upon the sale of forward commitments.

         REPURCHASE AGREEMENTS.  Each Fund may enter into repurchase agreements.
Repurchase  agreements are transactions in which a Fund purchases securities and
simultaneously  commits to resell the securities to the seller at an agreed-upon
date  or upon  demand  and at a  price  reflecting  a  market  rate of  interest
unrelated to the coupon rate or maturity of the purchased  securities.  Although
repurchase agreements carry certain risks not associated with direct investments
in securities,  including possible decline in the market value of the underlying
securities  and delays and costs to a Fund if the other party to the  repurchase
agreement becomes bankrupt, the Fund enters into repurchase agreements only with
banks,  securities  dealers  or  their  respective  affiliates  in  transactions
believed by Mitchell Hutchins to present minimum credit risks in accordance with
guidelines established by the Fund's Board of Directors.

         ILLIQUID  SECURITIES.  Some or all of the securities in which each Fund
invests may, when purchased,  be illiquid or may  subsequently  become illiquid.
The term "illiquid  securities" for this purpose means securities that cannot be
disposed  of  within  seven  days  in  the   ordinary   course  of  business  at
approximately the amount at which a Fund has valued the securities and includes,
among other  things,  purchased  over-the-counter  ("OTC")  options,  repurchase
agreements  maturing in more than seven days,  certain loan  participations  and
assignments,  and restricted  securities other than those Mitchell  Hutchins has
determined are liquid pursuant to guidelines  established by the Fund's Board of
Directors. To the extent a Fund invests in illiquid securities, the Fund may not
be able to  readily  liquidate  such  investments,  and would have to sell other
investments if necessary to raise cash to meet its obligations.

         Each Board of Directors has delegated the function of making day-to-day
determinations of liquidity to Mitchell Hutchins pursuant to guidelines approved
by each Board.  Mitchell  Hutchins will take into account a number of factors in
reaching  liquidity  decisions,  including  (1) the  frequency of trades for the
security,  (2) the number of dealers that make quotes for the security,  (3) the
number of dealers that have undertaken to make a market in the security, (4) the
number of other potential  purchasers for the security and (5) the nature of the
security  and how  trading  is  effected  (e.g.,  the  time  needed  to sell the

<PAGE>

security,  how bids are  solicited,  and the  mechanics of  transfer).  Mitchell
Hutchins  will monitor the  liquidity of  restricted  securities  in each Fund's
portfolio and report periodically on such decisions to each Board of Directors.

         HEDGING AND OTHER STRATEGIES USING  DERIVATIVE  INSTRUMENTS.  Each Fund
may  attempt  to reduce the  overall  risk of its  investments  (hedge) by using
options,  futures  contracts,  options on futures  contracts,  forward  currency
contracts  and  interest  rate  swap  transactions  and  may use  options  (both
exchange-traded  and OTC), futures  contracts,  options on futures contracts and
forward currency contracts to attempt to enhance income, realize gains or manage
the Fund's foreign currency  exposure.  A Fund's ability to use these derivative
instruments  may be  limited  by market  conditions,  regulatory  limits and tax
considerations.  The  SAI  contains  further  information  on  these  derivative
instruments.

                                       29

         Each Fund may  enter  into  forward  currency  contracts,  buy and sell
foreign  currency,  debt and equity  security  index and  interest  rate futures
contracts,  write  covered  put and call  options  and buy and sell put and call
options on securities,  debt and equity security indices, foreign currencies and
such futures contracts. A Fund may enter into options, futures, forward currency
contracts and swap  transactions  that  approximate (but do not exceed) the full
value of its portfolio, at which point up to 100% of the Fund's portfolio assets
would be subject to the risks associated with the use of these instruments.

         Each Fund may enter into swap  transactions,  including  interest  rate
swaps and  interest  rate caps,  floors and  collars,  for hedging or other risk
management  purposes.  For  example,  a Fund may enter into  interest  rate swap
transactions  to  preserve  a return  or spread on a  particular  investment  or
portion of its  portfolio  or to protect  against  any  increase in the price of
securities  the Fund  anticipates  purchasing at a later date. A Fund will enter
into swap  transactions  only with banks and  recognized  securities  dealers or
their  respective  affiliates that are believed by Mitchell  Hutchins to present
minimal  credit risks in accordance  with  guidelines  established by the Fund's
Board of Directors.

         Each  Fund  might  not  employ  any of the  derivative  instruments  or
strategies  described  above,  and there can be no assurance that any derivative
instrument  or strategy  used will  succeed.  If Mitchell  Hutchins  incorrectly
forecasts  interest  rates,  currency  exchange  rates,  market  values or other
economic factors in utilizing a derivative instrument for a Fund, the Fund might
have been in a better  position had it not hedged at all. The use of  derivative
instruments and strategies  involves  certain  special risks,  including (1) the
fact that skills needed to use derivative  instruments  are different from those
needed to select a Fund's  securities,  (2) possible imperfect  correlation,  or
even no correlation, between price movements of these derivative instruments and
price  movements  of the  investments  being  hedged,  (3) the fact that,  while
derivative instruments and strategies can reduce the risk of loss, they can also
reduce  the  opportunity  for gain,  or even  result in  losses,  by  offsetting
favorable price movements in hedged  investments and (4) the possible  inability
of a Fund to  purchase or sell a  portfolio  security  at a time that  otherwise
would be favorable  for it to do so, or the  possible  need for a Fund to sell a
portfolio  security at a  disadvantageous  time, due to the need for the Fund to
maintain  "cover" or to  segregate  securities  in  connection  with  derivative
instruments and the possible  inability of the Fund to close out or to liquidate
its hedged position.

<PAGE>

         New financial  products and risk management  techniques  continue to be
developed.  Each Fund may use these new  products and  techniques  to the extent
consistent  with its investment  objectives and with  regulatory and federal tax
considerations.

TEMPORARY AND DEFENSIVE STRATEGIES AND BORROWINGS

         Each Fund may implement  various  temporary or defensive  strategies at
times when  Mitchell  Hutchins  determines  that  conditions in the markets make
pursuing  the  Fund's  basic  investment  strategy  inconsistent  with  the best
interests of its stockholders. When unusual market or economic conditions occur,
Plus Fund may, for temporary defensive purposes,  invest up to 100% of its total
assets or, for  liquidity  purposes,  invest up to 35% of its total  assets,  in
securities  issued or  guaranteed  by the U.S.  government  or its  agencies  or
instrumentalities,  certificates of deposit,  bankers' acceptances or other bank
obligations,  commercial  paper or other  income  securities  deemed by Mitchell
Hutchins to be consistent with a defensive posture, or it may hold cash. At such
times,   Mitchell  Hutchins  may  temporarily   implement  various   alternative
strategies for High Yield Fund, designed primarily to reduce fluctuations in the
value of the Fund's assets. In implementing these "defensive"  strategies,  High
Yield  Fund  may  invest  in  money   market   instruments   of  all  types  and
higher-quality debt securities.  These strategies may include an increase in the
portion of the Funds' assets invested in higher-quality  debt securities,  which
generally  have  lower  yields  than  do  lower-rated  securities.  Since  these
investments  provide  relatively  low income,  a defensive  position  may not be
consistent with achieving the Funds' investment objectives.

         In addition to its  authority  to use leverage up to an amount equal to
33 1/3% of its total assets  (including  the amount of  leverage), Plus Fund may
borrow money for temporary or emergency purposes (e.g., settlement and clearance
of securities  transactions and payments of dividends to common or any preferred
stockholders)  in an amount not  exceeding  5% of the value of the Fund's  total
assets (not  including the amount  borrowed for this  purpose).  High Yield Fund
also may borrow money for temporary or emergency  purposes  (e.g.,  clearance of
transactions  or  payments  of  dividends  to  stockholders)  in an  amount  not
exceeding 10% of the value of the Fund's total assets (not  including the amount
borrowed).

CERTAIN ANTI-TAKEOVER PROVISIONS OF THE ARTICLES OF INCORPORATION

         Each Fund  presently has  provisions  in its Articles of  Incorporation
that have the effect of limiting (1) the ability of other entities or persons to
acquire  control  of the Fund,  (2) the  Fund's  freedom  to  engage in  certain
transactions,  and (3) the ability of the Fund's  Directors or  stockholders  to
amend the  Articles  of  Incorporation.  These  provisions  of the  Articles  of
Incorporation may be regarded as "anti-takeover" provisions.  Under Maryland law
and each Fund's Articles of  Incorporation,  the affirmative vote of the holders
of at least a majority  of the votes  entitled  to be cast is  required  for the
consolidation of the Fund with another corporation, a merger of the Fund with or
into another  corporation  (except for certain  mergers in which the Fund is the
successor), a statutory share exchange in which the Fund is not the successor, a
sale  or  transfer  of all or  substantially  all of  the Fund's  assets,  the
dissolution   of  the  Fund  and  any  amendment  to  the  Fund's   Articles  of
Incorporation.  In addition,  the affirmative vote of the holders of at least 66
2/3% (which is higher than that required  under Maryland law or the 1940 Act) of
the  outstanding  shares of a Fund's  capital  stock is  required  generally  to
authorize any of the following  transactions  or to amend the  provisions of the
Articles of Incorporation relating to such transactions:

<PAGE>

                  (1) merger,  consolidation or statutory  share exchange of the
         Fund with or into any other corporation;

                  (2) issuance of any  securities  of the  Fund to any person or
         entity for cash;

                  (3) sale,  lease or exchange of all or any substantial part of
         the assets of the  Fund to any entity or person  (except  assets having
         an aggregate market value of less than $l,000,000); or

                  (4) sale,  lease or  exchange to the  Fund,  in  exchange  for
         securities of the  Fund, of any assets of any entity or person  (except
         assets having an aggregate fair market value of less than $1,000,000)

if such  corporation,  person or  entity  is  directly,  or  indirectly  through
affiliates,  the beneficial  owner of more than 5% of the outstanding  shares of
each Fund (a "Principal Stockholder"). A similar vote also would be required for
any  amendment  of the  Articles  of  Incorporation  to convert  a    Fund to an
open-end  investment  company by making any class of each Fund's capital stock a
"redeemable  security," as that term is defined in the 1940 Act. Such vote would
not be required  with  respect to any of the  foregoing  transactions,  however,
when,  under  certain   conditions,   the   Board  of  Directors   approves  the
transaction,  although  in certain  cases  involving  merger,  consolidation  or
statutory  share  exchange  or sale of all or  substantially  all of the  Fund's
assets or the  conversion of the  Fund to an open-end  investment  company,  the
affirmative vote of the holders of a majority of the outstanding  shares of  the
Fund's capital stock would  nevertheless  be required.  Reference is made to the
Articles of  Incorporation of each Fund, on file with the SEC, for the full text
of these provisions.

         The  provisions of the Articles of  Incorporation  described  above and
each Fund's right to repurchase or make a tender offer for its shares could have
the effect of depriving the  stockholders of  opportunities to sell their shares
at a premium over  prevailing  market prices by  discouraging a third party from
seeking to obtain control of each Fund in a tender offer or similar transaction.
See  "Additional  Information  About  Both  Funds-Stock  Repurchases  and Tender
Offers." The overall effect of these  provisions is to render more difficult the
accomplishment  of a  merger  or  the  assumption  of  control  by  a  Principal
Stockholder.  They  provide,  however,  the advantage of  potentially  requiring
persons seeking control of a Fund to negotiate with its management regarding the
price to be paid and  facilitating  the  continuity  of the  Fund's  management,
investment objective and policies. Each Fund's Board of Directors has considered
the foregoing  anti-takeover  provisions and concluded that they are in the best
interests of the Fund and its stockholders.

DESCRIPTION OF CAPITAL STOCK

         Plus Fund is authorized to issue 200 million  shares of capital  stock,
$0.001 par value.  High Yield Fund is authorized to issue 100 million  shares of
capital stock,  $0.001 par value, all of which currently is classified as common
stock.  The  Board of  Directors  of each Fund is  authorized  to  classify  and
reclassify any unissued  shares of capital stock from time to time by setting or
changing  the   preferences,   conversion  or  other  rights,   voting   powers,
restrictions,  limitations as to dividends or terms and conditions of redemption
of such shares by the Fund.  The  information  contained  under this  heading is
subject to the provisions contained in each Fund's Articles of Incorporation and
Bylaws.

                                       31
<PAGE>

         COMMON STOCK.  Each Fund's  shares of common stock have no  preemptive,
conversion,  exchange  or  redemption  rights.  Each  share  has  equal  voting,
dividend,  distribution and liquidation rights. The outstanding shares of common
stock are fully paid and  non-assessable.  Stockholders are entitled to one vote
per share,  with fractional votes for fractional  shares.  All voting rights for
the election of Directors  are  non-cumulative,  which means that the holders of
more than 50% of the shares can elect 100% of the Directors  then  nominated for
election  if  they  choose  to do so and,  in such  event,  the  holders  of the
remaining shares will not be able to elect any Directors.

         Under the rules of the NYSE applicable to listed  companies,  each Fund
normally is required to hold an annual meeting of  stockholders in each year. If
a Fund is converted to an open-end investment company or if for any other reason
the  Fund's  shares  are no longer  listed  on the NYSE (or any  other  national
securities exchange the rules of which require annual meetings of stockholders),
the Fund may decide not to hold annual meetings of stockholders.

         Any  additional  offerings of the common stock,  if made,  will require
approval of the relevant  Fund's  Board of Directors  and will be subject to the
requirement  of the 1940 Act that  shares  may not be sold at a price  below the
then  current  net  asset  value,   exclusive  of  underwriting   discounts  and
commissions,  except,  among other  things,  in  connection  with an offering to
existing  stockholders  or with the  consent of a majority of the holders of the
Fund's outstanding voting securities.

         The  following   chart   indicates  the  shares  of  the  common  stock
outstanding for each Fund as of January 31, 2000:

         STOCK  REPURCHASES AND TENDER OFFERS. In recognition of the possibility
that the  common  stock  might  trade at a  discount  from NAV and that any such
discount may not be in the best interest of  stockholders,  each Fund's Board of
Directors has determined  that it will from time to time consider  taking action
to attempt to reduce or eliminate any discount.  To that end, each Board may, in
consultation with Mitchell Hutchins, from time to time consider action either to
repurchase  Fund  shares in the open  market or to make a tender  offer for Fund
shares at NAV. Each Board currently intends at least annually to consider making
such open market repurchases or tender offers and at such time may consider such
factors as the market  price of the Fund's  shares,  the NAV of the shares,  the
liquidity of the assets of the Fund,  whether such transactions would impair the
Fund's  status as a RIC or result in a failure to comply with  applicable  asset
coverage  requirements,  general  economic  conditions  and such other events or
conditions  that may have a material  effect on the Fund's ability to consummate
such transactions.  Under certain circumstances, it is possible that open market
repurchases or tender offers may constitute  distributions under the Code to the
remaining stockholders of the Fund. Each Board may at any time, however,  decide
that the Fund should not repurchase shares or make a tender offer. Each Fund may
borrow to finance  repurchases  and tender offers.  Interest on such  borrowings
will reduce the Fund's net income.

<PAGE>

         There is no assurance that  repurchases or tender offers will result in
Fund shares trading at a price that is equal or close to its net asset value per
share.  The market price of a Fund's shares will be  determined  by, among other
things,  the relative  demand for and supply of such shares in the market,  each
Fund's  investment  performance,  each Fund's  dividends  and yield and investor
perception of each Fund's  overall  attractiveness  as an investment as compared
with other  investment  alternatives.  Nevertheless,  the fact that each  Fund's
shares may be the  subject of tender  offers at NAV from time to time may reduce
the spread that might  otherwise  exist  between the market  price of the common
stock and NAV per share.  In the  opinion of Mitchell  Hutchins,  sellers may be
less  inclined  to  accept a  significant  discount  if they  have a  reasonable
expectation of being able to recover NAV in conjunction  with a possible  tender
offer.

                                       32

         Although each Board of Directors  believes that stock  repurchases  and
tender offers generally would have a favorable effect on the market price of the
common stock, it should be recognized that a Fund's acquisition of shares of the
common stock would  decrease each Fund's total assets and,  therefore,  have the
effect of increasing  each Fund's expense ratio. In addition,  such  acquisition
would have the effect of decreasing  asset coverage with respect to any leverage
being  used by Plus  Fund.  Because  of the  nature  of each  Fund's  investment
objective,  policies and portfolio,  under current market  conditions,  Mitchell
Hutchins  anticipates  that  repurchases and tender offers  generally should not
have a material,  adverse  effect on a Fund's  investment  performance  and that
Mitchell Hutchins generally should not have any material difficulty in disposing
of portfolio  securities in order to  consummate  stock  repurchases  and tender
offers; however, this may not always be the case.

         Any tender  offer made by a Fund for shares of common  stock  generally
would be at a price equal to the NAV of the shares on a date  subsequent  to the
Fund's receipt of all tenders.  Each offer would be made,  and the  stockholders
would be notified,  in accordance with the  requirements of the Exchange Act and
the 1940 Act, either by publication or mailing or both.  Each offering  document
would contain such  information  as is prescribed by such laws and the rules and
regulations  promulgated  thereunder.  Each person tendering shares would pay to
the  Fund's  Transfer  Agent a service  charge  to help  defray  certain  costs,
including  the  processing  of tender  forms,  effecting  payment,  postage  and
handling.  Any such  service  charge  would be paid  directly  by the  tendering
stockholder  and would not be deducted  from the proceeds of the  purchase.  The
Fund's  Transfer  Agent would  receive the fee as an offset to these costs.  The
Fund  expects  that the costs of  effecting  a tender  offer  would  exceed  the
aggregate of all service  charges  received  from those who tender their shares.
Costs associated with the tender would be charged against capital.

         Tendered  shares of common stock that have been  accepted and purchased
by a Fund  will be held in the  Fund's  treasury  until  retired  by a Board  of
Directors.  If  tendered  shares  are not  retired,  the Fund may hold,  sell or
otherwise  dispose of the shares for any lawful corporate  purpose as determined
by each Board.

         CONVERSION  TO  OPEN-END  INVESTMENT  COMPANY.  Each  Fund's  Board  of
Directors  will  consider  from  time to time  whether  it  would be in the best
interests  of the Fund and its  stockholders  to convert the Fund to an open-end
investment  company.  If a Board of Directors  determines that such a conversion
would  be in the  best  interests  of  the  Fund  and  its  stockholders  and is
consistent with the 1940 Act, the Board will submit to the Fund's  stockholders,

<PAGE>

at the next succeeding annual or special meeting, a proposal to amend the Fund's
Articles of  Incorporation  to so convert the Fund. Such amendment would provide
that,  upon its  adoption  by the  holders of at least a majority  of the Fund's
outstanding  shares  entitled to vote  thereon,  the Fund would  convert  from a
closed-end to an open-end investment company. If a Fund converted to an open-end
investment  company,  it would be able to continuously  issue and offer for sale
shares of common  stock,  and each such share could be  presented to the Fund at
the option of the holder  thereof  for  redemption  at a price based on the then
current NAV per share.  In such event,  the Fund could be required to  liquidate
portfolio securities to meet requests for redemption,  the common stock would no
longer be listed on the NYSE and certain investment  policies of each Fund would
require  amendment.  Plus Fund would also be required to redeem any  outstanding
preferred stock and any indebtedness not  constituting  bank loans,  which could
eliminate or alter Plus Fund's leveraged capital structure.

         In  considering  whether to propose  that a Fund convert to an open-end
investment  company,  the relevant  Board of  Directors  will  consider  various
factors, including, without limitation, the potential benefits and detriments to
the Fund and its stockholders of conversion,  the potential alternatives and the
benefits and detriments associated therewith,  and the feasibility of conversion
given, among other things, the Fund's investment objective and policies.  In the
event of a conversion to an open-end  investment company, a Fund may charge fees
in  connection  with the  sale or  redemption  of its  shares.  There  can be no
assurance  that either Board will conclude that such a conversion is in the best
interest of the Fund or its stockholders.  As an open-end  investment company, a
Fund may reserve the right to honor any request for redemption by making payment
in whole or in part in securities  chosen by the Fund and valued in the same way
as they would be valued for purposes of computing  the Fund's NAV. If payment is
made in securities,  a stockholder  may incur  brokerage  expenses in converting
these securities into cash.

                                       33

TAXATION

         Each Fund intends to continue to qualify  for  treatment  as a RIC. For
each taxable year that a Fund so qualifies,  the Fund (but not its stockholders)
will be relieved  of federal  income tax on the part of its  investment  company
taxable income  (consisting  generally of net investment  income, net short-term
capital gain and net gains from certain foreign currency  transactions)  and net
capital gain that it distributes to its stockholders.

         Dividends from a Fund's  investment  company  taxable  income  (whether
received in cash or reinvested in additional Fund shares)  generally are taxable
to  stockholders  as ordinary  income to the extent of the Fund's  earnings  and
profits. Distributions of a Fund's net capital gain (whether received in cash or
reinvested in additional  Fund shares) are taxable to  stockholders as long-term
capital gain, regardless of how long they have held their Fund shares.

         A  participant  in either  Reinvestment  Plan will be treated as having
received a  distribution  in the amount of the cash used to purchase Fund shares
on his or her  behalf,  including  a PRO  RATA  portion  of the  brokerage  fees
incurred by the Transfer Agent.  Distributions  by a Fund to stockholders in any
year that  exceed its  earnings  and  profits  generally  may be applied by each
stockholder  against his or her basis for Fund shares and will be taxable to any
stockholder  only  to  the  extent  the  distributions to the stockholder exceed

<PAGE>

the stockholder's basis for his or her Fund shares.

         An investor should be aware that, if Fund shares are purchased  shortly
before the record date for any dividend or other distribution, the investor will
pay full price for the shares and  receive  some  portion of the price back as a
taxable  distribution.  Stockholders  who are not liable for tax on their income
and whose shares are not  debt-financed are not required to pay tax on dividends
or other distributions they receive from the Funds.

         Each Fund notifies its stockholders  following the end of each calendar
year of the amounts of  dividends  and capital  gain  distributions  it paid (or
deemed paid) that year.

         Upon a sale or exchange of Fund shares  (including a sale pursuant to a
share  repurchase  or tender  offer by a Fund),  a  stockholder  generally  will
recognize  a taxable  gain or loss equal to the  difference  between  his or her
adjusted basis for the shares and the amount realized. Any such gain or loss (1)
will be treated as a capital  gain or loss if the shares are  capital  assets in
the  stockholder's  hands and (2) if the shares have been held for more than one
year, will be long-term capital gain or loss; provided that any loss realized on
a sale or  exchange of Fund shares that were held for six months or less will be
treated as a long-term, rather than as a short-term,  capital loss to the extent
of any capital gain distributions received thereon. A loss realized on a sale or
exchange  of Fund  shares  will be  disallowed  to the extent  those  shares are
replaced  by other  Fund  shares  within a period of 61 days  beginning  30 days
before  and ending 30 days after the date of  disposition  of the shares  (which
could  occur,  for example,  as the result of  participation  in a  Reinvestment
Plan). In that event,  the basis of the  replacement  shares will be adjusted to
reflect the disallowed loss.

         Each Fund may  acquire  zero  coupon or other  securities  issued  with
original issue discount ("OID").  As a holder of these  securities,  a Fund must
include in its gross  income the OID that accrues on the  securities  during the
taxable year,  even if it receives no  corresponding  payment on them during the
year.  A Fund  also  must  include  in gross  income  each  year any  "interest"
distributed in the form of additional securities on payment-in-kind  securities.
Because each Fund annually must distribute  substantially  all of its investment
company taxable income,  including any accrued OID and other non-cash income, to
satisfy the distribution  requirement imposed on RICs and to avoid imposition of
a 4% federal excise tax (see "Taxation" in the SAI), a Fund may be required in a
particular  year to  distribute as a dividend an amount that is greater than the
total amount of cash it actually receives. Those distributions will be made from
the Fund's cash assets or from the proceeds of sales of portfolio securities, if
necessary.  A Fund may realize  capital gains or losses from those sales,  which
would  increase or decrease its  investment  company  taxable  income and/or net
capital gain.

                                       34

         Each Fund is required to withhold  31% of all  dividends,  capital gain
distributions  and repurchase  proceeds  payable to any  individuals and certain
other  noncorporate  stockholders  who do not  provide  the Fund  with a correct

<PAGE>

taxpayer  identification  number.  Each Fund is also required to withhold 31% of
all dividends and capital gain  distributions  payable to those stockholders who
otherwise are subject to backup withholding.

         The  foregoing is only a summary of some of the  important  federal tax
considerations  generally affecting the Funds and their stockholders.  There may
be other federal,  state or local tax considerations  applicable to a particular
stockholder. Stockholders are urged to consult their tax advisers.

                                   APPENDIX A


          FORM OF AGREEMENT AND PLAN OF REORGANIZATION AND TERMINATION


        THIS AGREEMENT AND PLAN OF REORGANIZATION AND TERMINATION  ("Agreement")
is made  as of  _______,  2000,  between  Managed  High  Yield  Plus  Fund  Inc.
("Acquiring  Fund") and Managed High Yield Fund Inc.  ("Target"),  both Maryland
corporations.  (Acquiring  Fund and  Target  are  sometimes  referred  to herein
individually as a "Fund" and collectively as the "Funds.")

        The  Funds  desire  to  effect a  reorganization  described  in  section
368(a)(1)(C)  of the Internal  Revenue Code of 1986,  as amended  ("Code"),  and
intend this Agreement to be, and adopt it as, a "plan of reorganization"  within
the meaning of the  regulations  under section 368 of the Code  ("Regulations").
The  reorganization  will  involve the  transfer to  Acquiring  Fund of Target's
assets in exchange  solely for voting shares of common stock in Acquiring  Fund,
par value $0.001 per share  ("Acquiring  Fund  Shares"),  and the  assumption by
Acquiring   Fund  of  Target's   liabilities,   followed  by  the   constructive
distribution  of the Acquiring  Fund Shares PRO RATA to the holders of shares of
common stock in Target ("Target Shares") in exchange therefor,  all on the terms
and  conditions  set forth herein.  The foregoing  transactions  are referred to
herein collectively as the "Reorganization."

        Each Fund is a  closed-end  fund with a single  class of shares that are
currently purchased and sold on the New York Stock Exchange ("NYSE").

        In consideration of the mutual promises  contained  herein,  the parties
agree as follows:

1.      PLAN OF REORGANIZATION AND TERMINATION

        1.1. Target agrees to assign,  sell,  convey,  transfer, and deliver all
of its assets described in paragraph 1.2("Assets") to Acquiring Fund.  Acquiring
Fund agrees in exchange therefor

             (a) to issue and  deliver to Target  the  number of full  Acquiring
        Fund Shares plus  (i) fractional Acquiring Fund Shares, rounded  to  the
        third decimal place, for Stockholders (as defined in paragraph 1.5) that
        at  the  Effective  Time (as  defined in paragraph  3.1)  participate in
        Target's Dividend  Reinvestment Plan ("DRP Stockholders") and (ii)  cash
        in lieu of any fractional shares with respect to  Stockholders  that are
        not DRP Stockholders,  the  sum thereof  determined  by dividing the net
        value  of  Target (computed  as  set forth in  paragraph 2.1) by the net
        asset value ("NAV") of an Acquiring  Fund  Share  (computed as set forth
        in paragraph 2.2), and

             (b)  to assume all of Target's liabilities described  in  paragraph
        1.3 ("Liabilities").

Such transactions shall take place at the Closing (as defined in paragraph 3.1).

        1.2. The  Assets  shall  include,  without  limitation,  all cash,  cash
equivalents,   securities,   receivables   (including   interest  and  dividends
receivable),  claims and  rights of  action,  rights to  register  shares  under
applicable  securities  laws,  books and records,  deferred and prepaid expenses
shown as assets on Target's  books,  and other  property  owned by Target at the
Effective Time.

        1.3. The Liabilities shall include (except as otherwise provided herein)
all of Target's liabilities,  debts, obligations, and duties of whatever kind or
nature,  whether absolute,  accrued,  contingent,  or otherwise,  whether or not
arising in the ordinary course of business,  whether or not  determinable at the
Effective Time, and whether or not  specifically  referred to in this Agreement.


 <PAGE>

Notwithstanding  the  foregoing,  Target  agrees  to use  its  best  efforts  to
discharge all its known Liabilities before the Effective Time.

        1.4. At or immediately  before the Effective Time,  Target shall declare
and pay to its  stockholders a dividend  and/or other  distribution in an amount
large  enough so that it will  have  distributed  substantially  all (and in any
event not less than 90%) of its  investment  company  taxable  income  (computed
without regard to any deduction for dividends paid) and substantially all of its
realized  net capital  gain,  if any,  for its current  taxable year through the
Effective Time.

                                      A-1

        1.5.  At the  Effective  Time (or as soon  thereafter  as is  reasonably
practicable),  Target shall  distribute  the  Acquiring  Fund Shares and cash it
receives pursuant to paragraph 1.1 to its stockholders of record,  determined as
of the Effective Time (each a "Stockholder" and collectively "Stockholders"), in
constructive  exchange  for their  Target  Shares.  Such  distribution  shall be
accomplished by Acquiring  Fund's transfer agent's opening accounts on Acquiring
Fund's share transfer books in the  Stockholders'  names and  transferring  such
Acquiring Fund Shares thereto. Each Stockholder's account shall be credited with
the  respective  PRO RATA number of full  Acquiring  Fund  Shares  and,  for DRP
Stockholders,  fractional  Acquiring  Fund Shares,  rounded to the third decimal
point. Cash in lieu of any fractional Acquiring Fund Shares shall be distributed
to  all  other  Stockholders.  All  outstanding  Target  Shares,  including  any
represented by certificates,  shall simultaneously be canceled on Target's share
transfer books.

        1.6. Acquiring Fund shall not issue certificates  representing Acquiring
Fund Shares in  connection  with the  distribution  described in paragraph  1.5.
After  the  Effective  Time,  each  holder  of  an  outstanding  certificate  or
certificates formerly representing Target shares ("Old Certificate(s)") shall be
entitled  to  receive,  upon  surrender  of  his or her  Old  Certificate(s),  a
certificate representing the Acquiring Fund Shares distributable with respect to
the Target Shares  represented  by such Old  Certificate(s).  Promptly after the
Effective   Time,   the  Transfer  Agent  shall  mail  to  each  holder  of  Old
Certificate(s)  instructions and a letter of transmittal for use in surrendering
those certificate(s) for a certificate  representing those Acquiring Fund Shares
and cash in lieu of fractional  Acquiring Fund Shares, if appropriate.  Although
after the Effective  Time, Old  Certificates  will be deemed for all purposes to
evidence  ownership of Acquiring Fund Shares  distributable with respect thereto
in the Reorganization,  until a holder of Old Certificate(s) surrenders them, no
dividends  payable to the holders of record of  Acquiring  Fund Shares as of any
date  subsequent to the Effective  Time shall be paid to such holder.  If, after
the Effective  Time,  Old  Certificates  are presented to Acquiring  Fund,  such
certificates  shall be canceled and exchanged for certificates  representing the
number of Acquiring Fund shares distributable in the Reorganization with respect
to the Target Shares represented thereby.

        1.7. As  soon  as  reasonably  practicable  after  distribution  of  the
Acquiring Fund Shares pursuant to paragraph 1.5, but in all events within twelve
months after the  Effective  Time,  Target shall be  terminated  and any further
actions shall be taken in connection therewith as required by applicable law.

        1.8. Any reporting responsibility of Target to a public authority is and
shall  remain its  responsibility  up to and  including  the date on which it is
terminated.

        1.9. Any transfer  taxes payable on issuance of Acquiring Fund Shares in
a name other than that of the registered  holder on Target's books of the Target
Shares  constructively  exchanged  therefor  shall be paid by the person to whom
such Acquiring Fund Shares are to be issued, as a condition of such transfer.

2.      VALUATION

        2.1. For purposes of paragraph  1.1(a),  Target's net value shall be (a)
the value of the Assets  computed as of the close of regular trading on the NYSE
on the date of the Closing  ("Valuation Time"),  using the valuation  procedures
set forth in Target's most recent annual  report to its  stockholders,  less (b)
the amount of the Liabilities as of the Valuation Time.

        2.2. For purposes of  paragraph  1.1(a),  the NAV of an  Acquiring  Fund
Share shall be computed as of the Valuation Time, using the valuation procedures
set forth in Acquiring Fund's most recent annual report to its stockholders.

        2.3. All  computations  pursuant to paragraphs 2.1 and 2.2 shall be made
by or under the direction of Mitchell Hutchins Asset Management Inc.

3.      CLOSING AND EFFECTIVE TIME

         3.1.  The  Reorganization,  together  with  related  acts  necessary to
consummate the same  ("Closing"),  shall occur at the Funds' principal office on
May 26, 2000,  or at such other place  and/or on such other date as to which the
Funds may agree.  All acts taking  place at the Closing  shall be deemed to take
place  simultaneously as of the close of business on the date thereof or at such
other time as to which the Funds may agree ("Effective  Time").  If, immediately
before the Valuation  Time, (a) the NYSE is closed to trading or trading thereon
is  restricted  or (b)  trading  or the  reporting  of  trading  on the  NYSE or
elsewhere is disrupted,  so that  accurate  appraisal of the net value of Target
and the NAV of an Acquiring  Fund Share is  impracticable,  the  Effective  Time
shall be postponed  until the first business day after the day when such trading
shall have been fully resumed and such reporting shall have been restored.

        3.2. Target's  fund  accounting  and pricing  agent shall deliver at the
Closing a certificate of an authorized  officer  verifying that the  information
(including  adjusted  basis and holding  period,  by lot)  concerning the Assets
transferred by Target to Acquiring Fund, as reflected on Acquiring  Fund's books
immediately  following the Closing,  does or will conform to such information on
Target's books immediately before the Closing.  Target's custodian shall deliver
at the Closing a  certificate  of an  authorized  officer  stating  that (a) the
Assets  held by the  custodian  will be  transferred  to  Acquiring  Fund at the
Effective Time and (b) all necessary  taxes in conjunction  with the delivery of
the Assets, including all applicable federal and state stock transfer stamps, if
any, have been paid or provision for payment has been made.

        3.3. Target shall deliver to Acquiring Fund at the Closing a list of the
names and addresses of the  Stockholders  and the number of  outstanding  Target
Shares owned by each  Stockholder,  all as of the Effective  Time,  certified by
Target's Secretary or Assistant Secretary. Acquiring Fund's transfer agent shall
deliver at the Closing a certificate as to the opening on Acquiring Fund's share
transfer  books of accounts in the  Stockholders'  names.  Acquiring  Fund shall
issue and deliver a confirmation to Target  evidencing the Acquiring Fund Shares
to be credited to Target at the Effective Time or provide evidence  satisfactory
to Target that such Acquiring Fund Shares have been credited to Target's account
on Acquiring Fund's books. At the Closing,  each Fund shall deliver to the other
such bills of sale, checks, assignments, stock certificates,  receipts, or other
documents as the other Fund or its counsel may reasonably request.

        3.4. Each Fund shall  deliver to the other at the Closing a  certificate
executed in its name by its President or a Vice  President in form and substance
satisfactory  to the recipient and dated the Effective  Time, to the effect that
the  representations  and  warranties  it made in this  Agreement  are  true and
correct at the Effective Time except as they may be affected by the transactions
contemplated by this Agreement.

        thereunder  will be made,  at or prior to the  Effective  Time,  without
        either Fund's  incurring  any liability or penalty with respect  thereto
        and without diminishing or releasing any rights Target may have had with

        investigation  of or before any court or governmental  body is presently
        pending or (to Target's  knowledge)  threatened against Target or any of
        its properties or assets that, if adversely determined, would materially
        and  adversely  affect its  financial  condition  or the  conduct of its
        business; and Target knows of no facts that might form the basis for the
        institution of any such litigation,  proceeding, or investigation and is
        not a party to or subject to the  provisions  of any order,  decree,  or
        judgment of any court or governmental  body that materially or adversely
        affects  its  business  or its ability to  consummate  the  transactions
        contemplated hereby;

             4.1.7.  The execution,  delivery, and performance of this Agreement
        have been duly authorized as of the date hereof by all necessary  action
        on the  part  of  Target's  board  of  directors,  which  has  made  the
        determinations  required  by Rule  17a-8(a)  under  the 1940  Act;  and,
        subject to approval by Target's stockholders, this Agreement constitutes
        a valid  and  legally  binding  obligation  of  Target,  enforceable  in
        accordance  with  its  terms,  except  as the  same  may be  limited  by
        bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium,
        and similar  laws  relating  to or  affecting  creditors'  rights and by
        general principles of equity;

             4.1.8.  At the Effective  Time,  the  performance of this Agreement
        shall have been duly  authorized  by all  necessary  action by  Target's
        stockholders;

        of  this  Agreement  by  Target,  except  for (a) the  filing  with  the
        Securities and Exchange  Commission ("SEC") of a registration  statement

<PAGE>

        by Acquiring  Fund on Form N-14  relating to the  Acquiring  Fund Shares
        issuable   hereunder,   and  any   supplement   or   amendment   thereto
        ("Registration   Statement"),   including  therein  a   prospectus/proxy
        statement  ("Proxy  Statement"),  and  (b)  such  consents,   approvals,
        authorizations,  and  filings as have been made or received or as may be
        required subsequent to the Effective Time;

             4.1.10. On the effective date of the Registration Statement, at the
        time of the  stockholders'  meeting referred to in paragraph 5.2, and at
        the Effective  Time, the Proxy Statement will (a) comply in all material
        respects with the  applicable  provisions of the 1933 Act, the 1934 Act,
        and the 1940 Act and the rules and  regulations  thereunder  and (b) not
        contain  any  untrue  statement  of a  material  fact or omit to state a
        material  fact  required to be stated  therein or  necessary to make the
        statements  therein,  in light of the  circumstances  under  which  such
        statements were made, not misleading;  provided that the foregoing shall
        not apply to statements in or omissions from the Proxy Statement made in
        reliance on and in conformity  with  information  furnished by Acquiring
        Fund for use therein;

             4.1.11. The  Liabilities  were  incurred by Target in the  ordinary
        course of its business and are associated with the Assets; and there are
        no  Liabilities  other than  liabilities  disclosed  or provided  for in
        Target's  financial  statements  referred  to in  paragraph  4.1.17  and
        liabilities  incurred by Target in the  ordinary  course of its business
        subsequent  to July 31,  1999,  or  otherwise  previously  disclosed  to
        Acquiring  Fund,  none of  which  has  been  materially  adverse  to the
        business, assets, or results of Target operations;

                                      A-4

             4.1.12. Target  qualified for  treatment as a regulated  investment
        company  under  Subchapter  M of the Code  ("RIC") for each past taxable
        year since it  commenced  operations  and will  continue to meet all the
        requirements for such qualification for its current taxable year; it has
        no earnings  and profits  accumulated  in any taxable  year in which the
        provisions  of  Subchapter M did not apply to it; and the Assets will be
        invested  at all  times  through  the  Effective  Time in a manner  that
        ensures compliance with the foregoing;

             4.1.13. Target  is not  under  the  jurisdiction  of a  court  in a
        proceeding  under  Title 11 of the United  States  Code or similar  case
        within the meaning of section 368(a)(3)(A) of the Code;

             4.1.14. Not more than 25% of the  value of  Target's  total  assets
        (excluding cash, cash items, and U.S. government securities) is invested
        in the stock and securities of any one issuer,  and not more than 50% of
        the value of such assets is invested in the stock and securities of five
        or fewer issuers;

             4.1.15. Target's  federal  income tax returns,  and all  applicable
        state and local tax returns, for all taxable years through and including
        the taxable  year ended July 31,  1998,  have been timely  filed and all
        taxes payable pursuant to such returns have been timely paid; and

             4.1.16. Target's  financial  statements for the year ended July 31,
        1999,  to be delivered  to Acquiring  Fund,  fairly  represent  Target's
        financial position as of that date and the results of its operations and
        changes in its net assets for the year then ended.

        4.2. Acquiring Fund represents and warrants as follows:

             4.2.1.   Acquiring Fund is a  corporation  that is duly  organized,

        Acquiring  Fund's  assumption  of the  Liabilities)  will be  issued  in
        exchange for the Assets in the Reorganization;

             4.2.4.  The  Acquiring  Fund Shares to be issued and  delivered  to
        Target  hereunder will, at the Effective Time, have been duly authorized

        information  included on Form N-14 conform in all  material  respects to
        the  applicable  requirements  of the  1933 Act and the 1940 Act and the
        rules and regulations thereunder and do not include any untrue statement
        of a material  fact or omit to state any  material  fact  required to be

        and Restated  Bylaws or of any provision of any  agreement,  instrument,
        lease,  or other  undertaking  to which  Acquiring Fund is a party or by
        which it is bound or result in the  acceleration of any  obligation,  or
        the imposition of any penalty, under any agreement,  judgment, or decree
        to which  Acquiring  Fund is a party or by which it is bound,  except as
        previously disclosed in writing to and accepted by Target;

             4.2.7.  Except as otherwise disclosed in writing to and accepted by
        Target, no litigation, administrative proceeding, or investigation of or
        before  any  court or  governmental  body is  presently  pending  or (to
        Acquiring Fund's knowledge)  threatened against Acquiring Fund or any of
        its properties or assets that, if adversely determined, would materially
        and  adversely  affect its  financial  condition  or the  conduct of its

        for the institution of any such litigation, proceeding, or investigation
        and is not a party to or subject to the provisions of any order, decree,
        or  judgment  of any  court or  governmental  body  that  materially  or

                                      A-5

             4.2.8.  The execution,  delivery, and performance of this Agreement
        have been duly authorized as of the date hereof by all necessary  action
        on the part of  Acquiring  Fund's  board  of  directors  (together  with
        Target's  board  of  directors,  the  "Boards"),   which  has  made  the
        determinations  required by Rule  17a-8(a)  under the 1940 Act; and this
        Agreement   constitutes  a  valid  and  legally  binding  obligation  of
        Acquiring Fund,  enforceable in accordance with its terms, except as the
        same may be  limited by  bankruptcy,  insolvency,  fraudulent  transfer,
        reorganization,  moratorium,  and similar laws  relating to or affecting
        creditors' rights and by general principles of equity;

<PAGE>

             4.2.9. No  governmental  consents,  approvals,  authorizations,  or
        filings are required  under the 1933 Act, the 1934 Act, or the 1940 Act,

             4.2.10. On the effective date of the Registration Statement, at the
        time of the  stockholders'  meeting referred to in paragraph 5.2, and at
        the Effective  Time, the Proxy Statement will (a) comply in all material

        contain  any  untrue  statement  of a  material  fact or omit to state a
        material  fact  required to be stated  therein or  necessary to make the
        statements  therein,  in light of the  circumstances  under  which  such
        statements were made, not misleading;  provided that the foregoing shall
        not apply to statements in or omissions from the Proxy Statement made in
        reliance on and in conformity with  information  furnished by Target for
        use therein;

             4.2.11. Acquiring  Fund  qualified  for treatment as a RIC for each
        past  taxable year since it commenced  operations  and will  continue to
        meet all the requirements for such qualification for its current taxable
        year; it intends to continue to meet all such  requirements for the next
        taxable  year;  and it has no earnings  and profits  accumulated  in any
        taxable year in which the provisions of Subchapter M of the Code did not
        apply to it;

             4.2.12. Acquiring Fund has no plan or intention to issue additional
         Acquiring Fund Shares  following the  Reorganization  other than in the
         ordinary course of business pursuant to its Dividend Reinvestment Plan;
         nor does  Acquiring  Fund  have  any plan or  intention  to  redeem  or
         otherwise   reacquire   any   Acquiring   Fund  Shares  issued  to  the
         Stockholders pursuant to the Reorganization;

             4.2.13. Following  the  Reorganization,  Acquiring  Fund  (a)  will
        continue  Target's  "historic  business"  (within the meaning of section
        1.368-1(d)(2) of the Regulations) and (b) will use a significant portion
        of Target's  "historic  business  assets" (within the meaning of section
        1.368-1(d)(3) of the Regulations) in a business; furthermore,  Acquiring
        Fund (c) has no plan or intention to sell or otherwise dispose of any of
        the Assets,  except for dispositions made in the ordinary course of that
        business and dispositions necessary to maintain its status as a RIC, and
        (d) expects to retain  substantially  all the Assets in the same form as
        it  receives  them in the  Reorganization,  unless and until  subsequent
        investment  circumstances  suggest  the  desirability  of  change  or it
        becomes necessary to make dispositions thereof to maintain such status;

             4.2.14. There  is no plan or  intention  for  Acquiring  Fund to be
        dissolved or merged into another  corporation or a business trust or any
        "fund"  thereof  (within the meaning of section  851(g)(2)  of the Code)
        following the Reorganization;

             4.2.15. Immediately after the Reorganization, (a) not more than 25%
        of the value of  Acquiring  Fund's total assets  (excluding  cash,  cash
        items, and U.S. government securities) will be invested in the stock and
        securities  of any one  issuer and (b) not more than 50% of the value of
        such  assets will be  invested  in the stock and  securities  of five or
        fewer issuers;

                                      A-6

             4.2.16. Acquiring Fund does not directly or indirectly  own, nor at
        the  Effective  Time will it  directly  or  indirectly  own,  nor has it
        directly or  indirectly  owned,  at any time during the past five years,
        any shares of Target;

<PAGE>

             4.2.17. Acquiring  Fund's  federal  income  tax  returns,  and  all
        applicable  state and local tax returns,  for all taxable  years through
        and  including  the taxable  year ended May 31,  1999,  have been timely
        filed and all taxes  payable  pursuant to such  returns have been timely
        paid; and

             4.2.18. Acquiring  Fund's  financial  statements for the year ended
        May 31,  1999,  to be delivered to Target,  fairly  represent  Acquiring
        Fund's  financial  position  as of  that  date  and the  results  of its
        operations and changes in its net assets for the year then ended.

             4.3. Each Fund represents and warrants as follows:

             4.3.1.  The fair market value of the Acquiring Fund Shares received
        by each Stockholder will be approximately equal to the fair market value
        of its Target Shares constructively surrendered in exchange therefor;

             4.3.2.  Its  management  is  unaware  of any plan or  intention  of
        Stockholders  to sell or  otherwise  dispose of (a) any portion of their
        Target Shares before the  Reorganization  to any person related  (within
        the meaning of section  1.368-1(e)(3) of the Regulations) to either Fund
        or (b) any portion of the  Acquiring  Fund Shares to be received by them
        in the  Reorganization  to any person  related  (within such meaning) to
        Acquiring Fund;

             4.3.3.  The  Stockholders  will pay  their  own  expenses,  if any,
        incurred in connection with the Reorganization;

             4.3.4.  Immediately  following  consummation of the Reorganization,
        Acquiring Fund will hold substantially the same assets and be subject to
        substantially  the same  liabilities  that Target held or was subject to
        immediately  prior  thereto (in  addition to the assets and  liabilities
        Acquiring  Fund then held or was subject to), plus any  liabilities  and
        expenses of the parties incurred in connection with the Reorganization;

             4.3.5.  The fair  market  value of the  Assets  on a going  concern
        basis will equal or exceed the  Liabilities  to be assumed by  Acquiring
        Fund and those to which the Assets are subject;

             4.3.6.  There is no  intercompany  indebtedness  between  the Funds
        that was issued or acquired, or will be settled, at a discount;

             4.3.7.  Pursuant to the  Reorganization,  Target  will  transfer to
        Acquiring  Fund,  and Acquiring  Fund will acquire,  at least 90% of the
        fair market value of the net assets, and at least 70% of the fair market
        value  of the  gross  assets,  held by  Target  immediately  before  the
        Reorganization. For the purposes of this representation, any amounts (a)
        paid to Stockholders who receive cash or other property (whether in lieu
        of fractional Acquiring Fund Shares or otherwise) and (b) used by Target
        to  pay  its  Reorganization   expenses  and  to  make  redemptions  and
        distributions    immediately   before   the    Reorganization    (except
        distributions  made to  conform  to its  policy of  distributing  all or
        substantially all of its income and gains to avoid the obligation to pay
        federal income tax and/or the excise tax under section 4982 of the Code)
        will  be  included  as  assets  held  thereby   immediately  before  the
        Reorganization;

             4.3.8.  None of the compensation received by any Stockholder who is
        an  employee  of  or  service   provider  to  Target  will  be  separate
        consideration  for, or  allocable  to, any of the Target  Shares held by
        such Stockholder; none of the Acquiring Fund Shares received by any such
        Stockholder  will be separate  consideration  for, or allocable  to, any


                                      A-7
<PAGE>

        employment  agreement,  investment advisory agreement,  or other service
        agreement;  and the  consideration  paid to any such Stockholder will be
        for services  actually  rendered and will be  commensurate  with amounts
        paid to third parties bargaining at arm's-length for similar services;

             4.3.9.  Cash is being  distributed to the Stockholders that are not
        DRP  Stockholders in lieu of fractional  Acquiring Fund Shares solely to
        save  Acquiring  Fund the  expense  and  inconvenience  of  issuing  and
        transferring fractional shares to those Stockholders;  that distribution
        does  not  represent  separately  bargained-for   consideration  in  the
        Reorganization;  the total cash consideration paid to those Stockholders
        instead of issuing  fractional  Acquiring Fund Shares will not exceed 1%
        of the total  consideration  that will be issued to them in exchange for
        their  Target  Shares;   and  the  fractional  share  interests  of  the
        Stockholders will be aggregated, and no Stockholder will receive cash in
        an amount equal to or greater than the value of one full  Acquiring Fund
        Share;

             4.3.10. Immediately after the Reorganization, the Stockholders will
        not own shares  constituting  "control"  (within  the meaning of section
        304(c) of the Code) of Acquiring Fund; and

             4.3.11. Neither Fund will be reimbursed  for any expenses  incurred
        by it or on its  behalf in  connection  with the  Reorganization  unless
        those  expenses  are solely and directly  related to the  Reorganization
        (determined  in accordance  with the  guidelines  set forth in Rev. Rul.
        73-54, 1973-1 C.B. 187) ("Reorganization Expenses").

5.      COVENANTS

        5.1. Each Fund  covenants  to operate  its  respective  business  in the
ordinary  course  between the date hereof and the Closing,  it being  understood

        the transfer of the Assets to  Acquiring  Fund will not cause it to fail
        to be in compliance with all of its investment policies and restrictions
        immediately after the Closing.

        5.2. Target  covenants to call a  stockholders'  meeting to consider and

in compliance with applicable federal and state securities laws.

        5.7. Each Fund  covenants  that it will,  from time to time, as and when

delivered all such assignments and other instruments,  and will take or cause to
be taken such further action,  as the other Fund may deem necessary or desirable
in order to vest in, and confirm to, (a) Acquiring Fund, title to and possession
of all the Assets, and (b) Target, title to and possession of the Acquiring Fund
Shares to be  delivered  hereunder,  and  otherwise  to carry out the intent and
purpose hereof.

        5.8. Acquiring Fund  covenants to use all  reasonable  efforts to obtain
the  approvals  and  authorizations  required by the 1933 Act, the 1940 Act, and
such state  securities  laws it may deem  appropriate to continue its operations
after the Effective Time.

                                      A-8

        5.9. Subject to this Agreement,  each Fund covenants to take or cause to
be taken  all  actions,  and to do or cause  to be done all  things,  reasonably
necessary,  proper,  or advisable to consummate and effectuate the  transactions
contemplated hereby.

6.      CONDITIONS PRECEDENT

        Each Fund's obligations hereunder shall be subject to (a) performance by
the other Fund of all its obligations to be performed hereunder at or before the

<PAGE>

        6.4. Target shall have received an opinion of Kirkpatrick & Lockhart LLP
("Counsel") substantially to the effect that:

             6.4.1.  Acquiring  Fund is a  corporation  that is duly  organized,
        validly  existing,  and in good standing  under the laws of the State of
        Maryland with power under its Articles of  Incorporation  to own all its
        properties and assets and, to the knowledge of Counsel,  to carry on its
        business as presently conducted;

             6.4.2.  This Agreement (a) has been duly authorized,  executed, and
        delivered  by  Acquiring  Fund  and  (b)  assuming  due   authorization,
        execution,  and  delivery of this  Agreement  by Target,  is a valid and
        legally binding obligation of Acquiring Fund,  enforceable in accordance
        with  its  terms,  except  as the  same may be  limited  by  bankruptcy,
        insolvency, fraudulent transfer, reorganization, moratorium, and similar
        laws  relating  to  or  affecting   creditors'  rights  and  by  general
        principles of equity;

             6.4.3.  The Acquiring  Fund Shares to be issued and  distributed to
        the  Stockholders  under this Agreement,  assuming their due delivery as
        contemplated by this Agreement, will be duly authorized,  validly issued
        and outstanding, and fully paid and non-assessable;

             6.4.4.  The execution  and delivery of this  Agreement did not, and
        the  consummation  of the  transactions  contemplated  hereby  will not,
        materially violate Acquiring Fund's Articles of Incorporation or Amended
        and Restated Bylaws or any provision of any agreement (known to Counsel,
        without any  independent  inquiry or  investigation)  to which Acquiring
        Fund is a party or by which it is bound or (to the knowledge of Counsel,
        without  any  independent  inquiry  or  investigation)   result  in  the
        acceleration of any obligation,  or the imposition of any penalty, under
        any agreement, judgment, or decree to which Acquiring Fund is a party or
        by  which  it is  bound,  except  as set  forth  in such  opinion  or as
        previously disclosed in writing to and accepted by Target;

                                      A-9

             6.4.5. To the knowledge of Counsel (without any independent inquiry
        or investigation),  no consent, approval, authorization, or order of any
        court or  governmental  authority  is required for the  consummation  by
        Acquiring Fund of the  transactions  contemplated  herein,  except those
        obtained  under the 1933 Act,  the 1934 Act, and the 1940 Act, and those
        that may be required under state securities laws;

             6.4.6.  Acquiring Fund is registered  with the SEC as an investment
        company,  and to the  knowledge  of Counsel no order has been  issued or
        proceeding instituted to suspend such registration; and

             6.4.7.  To  the  knowledge  of  Counsel  (without  any  independent
        inquiry or investigation), (a) no litigation, administrative proceeding,
        or investigation of or before any court or governmental  body is pending
        or  threatened as to Acquiring  Fund or any of its  properties or assets
        and (b) Acquiring Fund is not a party to or subject to the provisions of
        any order,  decree,  or judgment of any court or governmental  body that
        materially  and adversely  affects its business,  except as set forth in
        such  opinion or as  otherwise  disclosed  in writing to and accepted by
        Target.

In rendering such opinion,  Counsel may (1) rely, as to matters  governed by the
laws of the State of Maryland,  on an opinion of competent Maryland counsel, (2)
make assumptions regarding the authenticity,  genuineness,  and/or conformity of
documents and copies thereof without independent verification thereof, (3) limit
such  opinion  to  applicable  federal  and state  law,  and (4) define the word
"knowledge"  and related  terms to mean the  knowledge  of  attorneys  then with
Counsel who have devoted  substantive  attention to matters  directly related to
this Agreement and the Reorganization.

<PAGE>

        6.5. Acquiring   Fund  shall  have   received   an  opinion  of  Counsel
substantially to the effect that:

             6.5.1.  Target is a  corporation  that is duly  organized,  validly
        existing,  and in good standing  under the laws of the State of Maryland
        with power under its Articles of Incorporation to own all its properties
        and assets and, to the knowledge of Counsel, to carry on its business as
        presently conducted;

             6.5.2.  This Agreement (a) has been duly authorized,  executed, and
        delivered by Target and (b) assuming due authorization,  execution,  and
        delivery of this  Agreement  by Acquiring  Fund,  is a valid and legally
        binding obligation of Target,  enforceable in accordance with its terms,
        except as the same may be limited by bankruptcy,  insolvency, fraudulent
        transfer,  reorganization,  moratorium,  and similar laws relating to or
        affecting creditors' rights and by general principles of equity;

             6.5.3.  The execution  and delivery of this  Agreement did not, and
        the  consummation  of the  transactions  contemplated  hereby  will not,
        materially  violate Target's Articles of Incorporation or By-Laws or any
        provision of any agreement  (known to Counsel,  without any  independent
        inquiry or  investigation)  to which Target is a party or by which it is
        bound or (to the knowledge of Counsel,  without any independent  inquiry
        or investigation)  result in the acceleration of any obligation,  or the
        imposition of any penalty,  under any agreement,  judgment, or decree to
        which Target is a party or by which it is bound,  except as set forth in
        such  opinion or as  previously  disclosed in writing to and accepted by
        Acquiring Fund;

             6.5.4. To the knowledge of Counsel (without any independent inquiry
        or investigation),  no consent, approval, authorization, or order of any
        court or  governmental  authority  is required for the  consummation  by
        Target of the transactions  contemplated  herein,  except those obtained
        under the 1933 Act,  the 1934 Act,  and the 1940 Act, and those that may
        be required under state securities laws;

             6.5.5.  Target is registered with the SEC as an investment company,
        and to the  knowledge of Counsel no order has been issued or  proceeding
        instituted to suspend such registration; and

             6.5.6.  To  the  knowledge  of  Counsel  (without  any  independent
        inquiry or investigation), (a) no litigation, administrative proceeding,
        or investigation of or before any court or governmental  body is pending
        or  threatened  as to Target or any of its  properties or assets and (b)
        Target is not a party to or  subject  to the  provisions  of any  order,
        decree,  or judgment of any court or  governmental  body that materially
        and adversely  affects  Target's  business,  except as set forth in such
        opinion  or as  otherwise  disclosed  in  writing  to  and  accepted  by
        Acquiring Fund.

                                      A-10

In rendering such opinion,  Counsel may (1) rely, as to matters  governed by the
laws of the State of Maryland,  on an opinion of competent Maryland counsel, (2)
make assumptions regarding the authenticity,  genuineness,  and/or conformity of
documents and copies thereof without independent verification thereof, (3) limit
such  opinion  to  applicable  federal  and state  law,  and (4) define the word
"knowledge"  and related  terms to mean the  knowledge  of  attorneys  then with
Counsel who have devoted  substantive  attention to matters  directly related to
this Agreement and the Reorganization.

<PAGE>

        6.6. Each Fund shall have  received an opinion of Counsel,  addressed to
and in form and  substance  satisfactory  to it, as to the  federal  income  tax
consequences  mentioned  below ("Tax  Opinion").  In rendering  the Tax Opinion,
Counsel may rely as to factual  matters,  exclusively  and  without  independent
verification,  on the  representations  made in this  Agreement  (which shall be
treated for those  purposes  as being made to  Counsel)  or in separate  letters
addressed to Counsel and the certificates  delivered  pursuant to paragraph 3.4.
The Tax Opinion shall be  substantially  to the effect that,  based on the facts
and   assumptions   stated  therein  and  conditioned  on  consummation  of  the
Reorganization  in  accordance  with this  Agreement,  for  federal  income  tax
purposes:

             6.6.1.  Acquiring  Fund's  acquisition  of the  Assets in  exchange
        solely for full and fractional  Acquiring Fund Shares (plus cash in lieu
        of certain  fractional  Acquiring  Fund  Shares)  and  Acquiring  Fund's
        assumption  of the  Liabilities,  followed by Target's  distribution  of
        those full  Acquiring  Fund Shares PRO RATA to all  Stockholders,  those
        fractional Acquiring Fund Shares PRO RATA to DRP Stockholders,  and such
        cash PRO RATA to the other Stockholders,  constructively in exchange for
        their Target Shares, will qualify as a reorganization within the meaning
        of section 368(a)(1)(C) of the Code, and each Fund will be "a party to a
        reorganization" within the meaning of section 368(b) of the Code;

             6.6.2. Target will recognize no gain or loss on the transfer of the
        Assets to Acquiring  Fund in exchange  solely for Acquiring  Fund Shares
        and  cash  in lieu of  certain  fractional  Acquiring  Fund  Shares  and
        Acquiring  Fund's  assumption of the  Liabilities  or on the  subsequent
        distribution   of  those  shares  and  cash  to  the   Stockholders   in
        constructive exchange for their Target Shares;

             6.6.3. Acquiring Fund will recognize no gain or loss on its receipt
        of the Assets in exchange solely for Acquiring Fund Shares (plus cash in
        lieu of certain fractional  Acquiring Fund Shares) and its assumption of
        the Liabilities;

             6.6.4.  Acquiring  Fund's  basis for the Assets will be the same as
        Target's  basis  therefor  immediately  before the  Reorganization,  and
        Acquiring  Fund's  holding  period for the Assets will include  Target's
        holding period therefor;

             6.6.5.  A  Stockholder  will  recognize  no  gain  or  loss  on the
        constructive  exchange of all the Stockholder's Target Shares solely for
        Acquiring Fund Shares,  and cash in lieu of a fractional  Acquiring Fund
        Share, where appropriate,  pursuant to the  Reorganization,  except with
        respect to such cash; and

             6.6.6.  A  Stockholder's  aggregate  basis for the  Acquiring  Fund
        Shares to be  received in the  Reorganization  will be the same  as  the
        aggregate basis for the Target Shares to be  constructively  surrendered
        in exchange  for those  Acquiring  Fund  Shares,  decreased  by any cash
        received,  and increased by any gain  recognized,  on the exchange.  Its
        holding period for those  Acquiring Fund Shares will include its holding
        period for those Target Shares,  provided the  Stockholder  held them as
        capital assets at the Effective Time.

Notwithstanding subparagraphs 6.6.2 and 6.6.4, the Tax Opinion may state that no
opinion is expressed as to the effect of the  Reorganization on the Funds or any
Stockholder with respect to any Asset as to which any unrealized gain or loss is
required  to be  recognized  for  federal  income tax  purposes  at the end of a
taxable year (or on the termination or transfer  thereof) under a mark-to-market
system of accounting.

                                      A-11

At any time  before  the  Closing,  either  Fund may waive any of the  foregoing
conditions  (except that set forth in paragraph  6.1) if, in the judgment of its
Board,  such waiver will not have a material adverse effect on its stockholders'
interests.

7.      BROKERAGE FEES AND EXPENSES
