                             Alice A. Pellegrino
                             Secretary

                           Frequently Asked Questions

      In this Question and Answer Sheet, we will refer to MuniAssets  Fund, Inc.
as MuniAssets and Merrill Lynch High Income  Municipal  Bond Fund,  Inc. as High
Income Municipal.

Q.    Why am I receiving this proxy?

A.    As a stockholder  of MuniAssets  or High Income  Municipal,  you are being
      asked  to  consider  a  transaction  in  which   MuniAssets  will  acquire
      substantially  all of  the  assets  and  assume  substantially  all of the
      liabilities of High Income  Municipal.  This transaction is referred to in
      this question and answer sheet as the  Reorganization.  The Reorganization
      requires  the approval of the  stockholders  of both  MuniAssets  and High
      Income Municipal.

Q.    Which Fund will be the Surviving  Fund and which Fund will be the Acquired
      Fund in the Reorganization?

A.    MuniAssets will be the Surviving  Fund. High Income  Municipal will be the
      Acquired Fund. The Surviving Fund is an  exchange-listed  closed-end  fund
      whereas High Income Municipal is a continuously offered closed-end fund.

Q.    How will the Reorganization benefit stockholders?

A.    Stockholders of High Income Municipal should consider the following:

      o     After the Reorganization, stockholders of High Income Municipal will
            be invested in a substantially larger,  non-diversified,  closed-end
            fund with an investment objective and policies substantially similar
            to High Income Municipal's investment objective and policies.

      o     After   the   Reorganization,   High   Income   Municipal's   common
            stockholders are expected to experience:

            o     lower expenses per share,

            o     economies of scale, and

            o     greater flexibility in portfolio management;

      o     After the Reorganization,  High Income Municipal common stockholders
            will no longer be subject to

            o     a separate administrative fee,

            o     expenses associated with required annual prospectus updates,

            o     expenses of conducting quarterly tender offers, or

            o     an early  withdrawal  charge  ("EWC")  upon the sale of shares
                  held for less than three years; and


      o     After the Reorganization, High Income Municipal stockholders will be
            able to sell  their  shares  on each day  that  the New  York  Stock
            Exchange  ("NYSE")  is open for  trading  at the market  price;  the
            market  price may be higher or lower than the net asset value of the
            shares  and  transactions  in shares  may be  subject  to  brokerage
            commissions or other charges.  Stockholders of High Income Municipal
            will no  longer be able to redeem  their  shares at net asset  value
            once per quarter.

      Stockholders of MuniAssets should consider the following:

      o     After  the  Reorganization,   MuniAssets  stockholders  will  remain
            invested in a  non-diversified , closed-end fund that has no changes
            to its current investment  objective but has a larger asset base and
            is expected to have a lower expense ratio; and

      o     After the Reorganization,  MuniAssets stockholders should experience
            economies of scale and greater flexibility in portfolio management.

Q.    Will the Reorganization change my privileges as a stockholder?

A.    Your privileges as a stockholder will not change in any substantial way as
      a result of the  Reorganization.  In addition,  the  stockholder  services
      available to you after the  Reorganization  will be substantially the same
      as the stockholder services currently available to you.

Q.    If I own shares of common stock of High Income  Municipal,  will I own the
      same  number  of  shares  of  common   stock  of   MuniAssets   after  the
      Reorganization as I currently own?

A.    No. You will receive  shares of common stock of  MuniAssets  with the same
      aggregate  net asset  value as the shares of common  stock of High  Income
      Municipal  you own on the  business  day prior to the closing  date of the
      Reorganization  (the "Valuation  Date").  The number of shares you receive
      will depend on the relative net asset values of the shares of common stock
      of the Funds on that date.

      For example,  let us assume that you own 10 shares of common stock of High
      Income  Municipal.  If the net asset value of High Income Municipal common
      stock on the  Valuation  Date is $6 per share,  and the net asset value of
      MuniAssets  common stock on the Valuation Date is $12 per share,  you will
      receive 5 shares of  MuniAssets  common stock in the  Reorganization.  The
      aggregate net asset value of your investment  will not change.  (10 shares
      of High Income  Municipal  common stock x $6 = $60; 5 shares of MuniAssets
      common stock x $12 = $60).

      Thus, if on the Valuation  Date the net asset value of the common stock of
      MuniAssets  is higher than the net asset value of the common stock of High
      Income  Municipal,  you will  receive  fewer  shares  of  common  stock of
      MuniAssets in the  Reorganization  than you held in High Income  Municipal
      before the  Reorganization.  On the other hand,  if the net asset value of
      the common  stock of  MuniAssets  is lower than the net asset


                                       2


      value of the common  stock of High Income  Municipal,  you will  receive a
      greater   number  of  shares  of  common  stock  of   MuniAssets   in  the
      Reorganization.  The  aggregate  net asset value of your shares  after the
      Reorganization  will be the same as before the Reorganization  except that
      you may receive cash in lieu of fractional shares of MuniAssets.

      Note that because MuniAssets is traded on the NYSE, the shares you receive
      will have both a net asset  value and a market  price.  The  market  price
      reflects what other investors think the shares are worth and may be higher
      or lower than the net asset value.

Q.    Should I send in my stock certificates now?

A.    No. After the Reorganization is completed,  we will send holders of common
      stock of High Income Municipal  written  instructions for exchanging their
      stock  certificates.  High Income Municipal  stockholders  should exchange
      their stock  certificates  promptly after the  Reorganization  in order to
      continue to receive dividend payments on their shares.  Dividends declared
      will accrue but payments will not be made until the stock certificates for
      High Income Municipal are surrendered and exchanged for stock certificates
      of the Surviving  Fund.  Stockholders  of MuniAssets will keep their stock
      certificates.

Q.    What are the tax consequences for stockholders?

A.    The  Reorganization  is structured as a tax-free  transaction  so that the
      completion of the Reorganization  itself will not result in Federal income
      tax liability  for  stockholders  of either Fund,  except for taxes on any
      cash received for a fractional share of common stock.

Q.    Who will manage the Surviving Fund after the Reorganization?

A.    Fund Asset  Management L.P.  ("FAM") serves as the investment  adviser for
      MuniAssets and Merrill Lynch Investment Managers,  L.P. ("MLIM") serves as
      the  investment  adviser  for  High  Income  Municipal.  FAM and  MLIM are
      affiliates. FAM will be the investment adviser of the Surviving Fund after
      the  Reorganization.  Theodore R.  Jaeckel,  Jr.  currently  serves as the
      portfolio  manager  for  each  Fund  and  will  continue  to  serve as the
      portfolio manager for the Surviving Fund after the Reorganization.

Q.    Will there be a Stockholders' Meeting for each Fund?

A.    Yes, an Annual Meeting of  Stockholders of MuniAssets will be held at 9:00
      a.m. and a Special Meeting of  Stockholders of High Income  Municipal will
      be held at 10:00 a.m.  on October 24,  2001,  at 800  Scudders  Mill Road,
      Plainsboro, New Jersey.

Q.    Why is my vote important?

A.    Approval of the  Reorganization  requires the affirmative vote of (i) High
      Income Municipal  stockholders  representing a majority of the outstanding
      shares of High  Income  Municipal  Common  Stock  entitled  to vote on the
      matter,  and (ii) MuniAssets  stockholders  representing a majority of the
      votes cast with respect to the matter,  provided


                                       3


      that the total vote cast on the matter  represents over 50% in interest of
      all shares  entitled to vote on the matter.  For purposes of any vote at a
      Meeting, a quorum consists of a majority of the shares entitled to vote at
      that Meeting.  The Board of Directors of each Fund urges every stockholder
      to vote.  Please read all proxy materials  thoroughly  before casting your
      vote.

Q.    How can I vote?

A.    You may vote by signing  and  returning  your  proxy card in the  enclosed
      postage-paid  envelope.  You may also vote your shares on the  Internet at
      http://www.proxyvote.com.  On the Internet you will be asked for a control
      number  that you  received  in your  proxy  mailing.  You may also vote by
      telephone by calling the "800" number  printed on your voting  instruction
      form. Finally, you may vote in person at the Stockholders' Meeting. If you
      submitted  a proxy by  mail,  by  telephone  or on the  Internet,  you may
      withdraw  it at the  Meeting and then vote in person at the Meeting or you
      may submit a superseding proxy by mail, by telephone or on the Internet.

Q.    Have the Funds retained a proxy solicitation firm?

A.    Yes,  each  Fund  has  hired  Georgeson   Shareholder  to  assist  in  the
      solicitation  of proxies  for the  Meeting.  While the Funds  expect  most
      proxies to be  returned  by mail,  the Funds may also  solicit  proxies by
      telephone, fax, telegraph or personal interview.

Q.    What if there  are not  enough  votes to reach a quorum  by the  scheduled
      meeting date?

A.    In order to  ensure  that we  receive  enough  votes,  we may need to take
      further action. We or our proxy  solicitation firm may contact you by mail
      or telephone. Therefore, we encourage stockholders to vote as soon as they
      review the  enclosed  proxy  materials  to avoid  additional  mailings  or
      telephone  calls.  If enough  shares  are not  represented  at either  the
      MuniAssets  Annual Meeting or the High Income Municipal Special Meeting to
      achieve the necessary  quorum or the necessary quorum is present but there
      are not sufficient votes to take action on the proposal by the time of the
      Meetings  on October  24,  2001,  the Annual  Meeting  and/or the  Special
      Meeting may be adjourned to permit further solicitation of proxy votes.

Q.    What is the Board's recommendation?

A.    The Board of Directors of each Fund believes the  Reorganization is in the
      best  interests  of  that  Fund  and  its   stockholders   and  encourages
      stockholders to vote FOR the Reorganization.
