                         relating to the acquisition by

              a series of PIMCO Funds: Multi-Manager Series ("MMS")



                                  INTRODUCTION


         This Proxy  Statement/Prospectus  provides you with information about a
proposed  reorganization in which all of the assets of the Tax Exempt Fund would
be acquired by the Municipal  Bond Fund, in exchange for shares of the Municipal
Bond Fund and the assumption by the Municipal Bond Fund of the Tax Exempt Fund's
liabilities (the  "Reorganization").  Shares of the Municipal Bond Fund received
by the Tax  Exempt  Fund would be  distributed  to the  shareholders  of the Tax
Exempt  Fund,  and the Tax Exempt Fund would be  terminated.  As a result of the
Reorganization,  each  shareholder  of the Tax Exempt  Fund would  receive  that
number of full and fractional shares of the corresponding class of the Municipal
Bond Fund having an aggregate  net asset value equal to the  aggregate net asset
value of the shareholder's shares of the Tax Exempt Fund held as of the close of
business on the date of the exchange.

         This Proxy  Statement/Prospectus,  which you  should  retain for future
reference,  sets forth concisely the  information  about the Municipal Bond Fund
that a  prospective  investor  should know  before  investing.  A  Statement  of
Additional  Information dated April __, 1998 containing  additional  information
about  the  Reorganization  and the  parties  thereto  has been  filed  with the
Securities and Exchange  Commission (the "SEC") and is incorporated by reference
into this Proxy  Statement/Prospectus.  A copy of the  Statement  of  Additional
Information  is  available  upon  request by calling  (800)  426-0107.  For more
information  about PIMS and the  Municipal  Bond Fund,  see the Class A, B and C
prospectus  and the Statement of  Additional  Information  for PIMS,  each dated
April 1, 1998,  which are  incorporated  herein by reference and copies of which
may be obtained  without charge by calling (800) 426-0107.  For more information
about MMS and the Tax Exempt Fund, see the Class A, B and C prospectuses for MMS
dated  February  5, 1998 and April 1,  1998,  and the  Statement  of  Additional
Information  for MMS  dated  April 1,  1998,  which are  incorporated  herein by
reference  and copies of which may be obtained  without  charge by calling (800)
426-0107.   The  SEC   maintains   an   Internet   World   Wide   Web  site  (at
http://www.sec.gov)  which  contains the  Statements of Additional  Information,
materials  that  are   incorporated  by  reference  into  the  prospectuses  and
Statements of Additional Information,  and other information about PIMS, MMS and
the Funds. In addition,  PIMS and MMS provide  periodic  reports to shareholders
containing  relevant  information  regarding  the  Funds,  including  investment
results and  reviews of  portfolio  changes.  You may receive a copy of the most
recent annual and semi-annual  report for MMS, without charge,  by calling (800)
426-0107.  The  Municipal  Bond Fund has not yet  completed  a fiscal  year,  or
portion  thereof,  that  has  been  reported  in a report  to  shareholders,  so
information regarding the Municipal Bond Fund does not appear in the latest PIMS
annual or semi-annual reports.
<PAGE>

         The  Municipal  Bond Fund is a series of PIMS,  an open-end  management
investment  company.  The Tax  Exempt  Fund is a  series  of  MMS,  an  open-end
management  investment company. The primary investment objective of each Fund is
to seek high current  income  exempt from federal  income tax,  consistent  with
preservation of capital. Unlike the Tax Exempt Fund, the Municipal Bond Fund has
the pursuit of capital appreciation as a secondary objective.

         These   securities  have  not  been  approved  or  disapproved  by  the
Securities  and  Exchange   Commission  nor  has  the  Securities  and  Exchange
Commission    passed   upon   the   accuracy   or   adequacy   of   this   Proxy
Statement/Prospectus. Any representation to the contrary is a criminal offense.

         Shares of the Municipal Bond Fund are not deposits or  obligations  of,
or  guaranteed  or endorsed by, any  financial  institution,  and shares are not
federally  insured by the Federal  Deposit  Insurance  Corporation,  the Federal
Reserve Board or any other agency, and entail risk,  including the possible loss
of principal.

                                    OVERVIEW


         The  following  is a summary of certain  information  contained in this
Proxy  Statement/Prospectus.  This summary is qualified by reference to the more
complete  information  contained  elsewhere  in this Proxy  Statement/Prospectus
(including appendices), the Prospectuses for Class A, B and C shares of PIMS and
the  Prospectuses  for  Class  A,  B and C  shares  of MMS  (each  of  which  is
incorporated herein by reference),  and the Agreement and Plan of Reorganization
dated as of April 7, 1998 (the "Reorganization Agreement"), which is attached to
this Proxy  Statement/Prospectus  as Appendix A.  Shareholders  should read this
entire Proxy Statement/Prospectus carefully.

         The Proposed  Reorganization.  The Board of Trustees of MMS,  including
the  Trustees  who are  not  "interested  persons"  of MMS  (as  defined  in the
Investment  Company  Act of 1940) (the  "Independent  Trustees"),  approved  the
Reorganization  Agreement  on March 5,  1998.  Subject  to its  approval  by the
shareholders of the Tax Exempt Fund, the  Reorganization  Agreement provides for
the  acquisition  by the  Municipal  Bond  Fund of all of the  assets of the Tax
Exempt  Fund  in  exchange  for  shares  of the  Municipal  Bond  Fund,  and the
assumption  by the  Municipal  Bond Fund of the Tax Exempt  Fund's  liabilities,
following which the shares of the Municipal Bond Fund received by the Tax Exempt
Fund would be distributed to the shareholders of the Tax Exempt Fund and the Tax
Exempt Fund would be  terminated.  The exchange of all of the Tax Exempt  Fund's
assets for shares of the  Municipal  Bond Fund and the  assumption of all of the
liabilities  of the Tax Exempt Fund by the  Municipal  Bond Fund are expected to
occur on June 26,  1998,  or such  other  date as the  parties  may  agree  (the
"Exchange Date").

         As a result of the  Reorganization,  each shareholder of the Tax Exempt
Fund would become a shareholder of the Municipal Bond Fund and would hold, after
the Exchange Date, that number of full and fractional Class A, Class B and Class
C Shares of the Municipal Bond Fund having an aggregate net asset value equal to
the  aggregate  net asset  value of each  respective  class of shares of the Tax
Exempt Fund held by that shareholder as of the close of business on the Exchange
Date.

         For  the  reasons  set  forth  below  under   "Information   About  the
Reorganization - Reasons for the  Reorganization," the Board of Trustees of MMS,
including the Independent  Trustees who were present to consider the matter, has
concluded  that the  Reorganization  is in the best  interests of the Tax Exempt
Fund and its  shareholders  and that the  interests of  shareholders  of the Tax
Exempt Fund will not be diluted as a result of the transactions  contemplated by
the  Reorganization  Agreement.  Accordingly,  the Board of Trustees  recommends
approval of the Reorganization Agreement. If the Reorganization Agreement is not
approved,  the Tax Exempt Fund will continue in  existence,  unless the Board of
Trustees advocates other action.

         Approval of the Reorganization Agreement with respect to the Tax Exempt
Fund  requires the  affirmative  vote of a plurality of the shares of beneficial
interest of the Tax Exempt Fund present and voting at the meeting.

         Investment Objectives and Policies. The Municipal Bond Fund and the Tax
Exempt Fund have  investment  objectives  and policies  which are  substantially
similar.  The primary investment objective of both Funds is to seek high current
income exempt from federal income tax,  consistent with preservation of capital.
The  Municipal  Bond Fund has capital  appreciation  as a  secondary  investment
objective.  Accordingly,  the Municipal  Bond Fund may be expected to generate a
somewhat higher percentage of taxable gain than the Tax Exempt Fund.
   
         The  Funds  seek  their  objectives  by  investing  primarily  in  debt
securities  whose  interest is, in the opinion of bond counsel for the issuer at
the time of  issuance,  exempt  from  federal  income tax  ("Municipal  Bonds"),
although  up to 20% of each  Fund's net assets may be invested in other types of
securities,  as  described  below.  While the  Funds'  investment  policies  are
substantially  similar, the Municipal Bond Fund may purchase securities that the
Tax Exempt Fund does not purchase,  such as Residual  Interest Bonds,  which may
subject the portion of the Municipal Bond Fund's portfolio invested therein to a
higher level of volatility than that of the Tax Exempt Fund.
    
         The  investment  objectives  and policies of the Funds are discussed in
more  detail  in  "Investment  Practices  and Risk  Considerations"  below.  For
complete  descriptions  of the investment  objectives and policies of the Funds,
please read each Fund's  prospectus  and  statement of  additional  information,
which are incorporated herein by reference.
   
         Investment  Advisers.  Pacific Investment  Management Company ("Pacific
Investment  Management"),  840 Newport Center Drive,  Newport Beach,  California
92660,  is the  investment  adviser to the  Municipal  Bond Fund  pursuant to an
investment  advisory  contract with PIMS.  Pacific  Investment  Management is an
investment  counseling firm founded in 1971, and had approximately  $118 billion
in assets under  management  as of December 31,  1997.  For further  information
about Pacific Investment  Management,  see "Management of the  Trust--Investment
Advisor" in Appendix B. The investment  adviser for the Tax Exempt Fund is PIMCO
Advisors L.P.  ("PIMCO  Advisors"),  800 Newport  Center Drive,  Newport  Beach,
California 92660, a Delaware limited partnership. As of December 31, 1997, PIMCO
Advisors and its subsidiary  partnerships had more than $199.5 billion in assets
under  management.  PIMCO  Advisors  employs  its  affiliate,   Columbus  Circle
Investors  ("Columbus  Circle"),   One  Station  Place,  8th  Floor,   Stamford,
Connecticut 06902, as Portfolio Manager of the Tax Exempt Fund. Accounts managed
by Columbus Circle had combined assets as of December 31, 1997 of  approximately
$9.3  billion.  Pacific  Investment  Management  and  Columbus  Circle  are each
subsidiary  partnerships of PIMCO Advisors.  Except with respect to the advisory
fee rates,  the investment  advisory  contract between MMS, on behalf of the Tax
Exempt  Fund,  and PIMCO  Advisors  is  substantially  similar  in all  material
respects to the investment advisory contract currently in place between PIMS, on
behalf of the Municipal Bond Fund, and Pacific Investment Management.
    
         Fees and  Expenses.  Each of the  Funds  features  fixed  advisory  and
administrative  fee rates. Each Fund pays its respective  investment adviser and
administrator monthly fees at the following annual rates:

    Fund's Class A, Class B and Class C shares.

         For its services as Portfolio Manager of the Tax Exempt Fund,  Columbus
Circle is paid a portfolio  management fee by PIMCO Advisors (and not by the Tax
Exempt  Fund)  equal,  on an annual  basis,  to 0.30% of the Tax  Exempt  Fund's
average daily net assets.  For more  information  about fees and  expenses,  see
"Fees and Expenses."

         Classes of Shares.  Each Fund currently  offers three classes of shares
that are  affected by the  proposed  Reorganization:  (1) Class A shares,  which
generally are sold subject to an initial sales charge; (2) Class B shares, which
are sold subject to a contingent  deferred sales charge; and (3) Class C shares,
which are sold  subject to an asset based  sales  charge.  Sales  charges are in
addition to the advisory and administrative  fees discussed above.  Shareholders
of the Tax Exempt Fund will not be charged a sales charge in connection with the
Reorganization,  although  Class B and Class C shares of the Municipal Bond Fund
acquired by Tax Exempt Fund shareholders in the  Reorganization  will be subject
to a  contingent  deferred  sales charge to the same extent that the Class B and
Class C shares,  respectively,  of the Tax Exempt Fund were so subject  prior to
their exchange for the Municipal Bond Fund shares.  For more  information  about
sales charges, see "Fees and Expenses."

         Purchase,   Redemption,   and  Exchange   Information.   The  purchase,
redemption  and exchange  procedures  and privileges for the Tax Exempt Fund and
the Municipal Bond Fund are substantially  the same. For further  information on
the  purchase,  redemption  and  exchange  procedures  and  privileges  for  the
Municipal Bond Fund, see Appendix B.

         Federal Income Tax Consequences of the  Reorganization.  It is expected
that the  Reorganization  will constitute a tax-free  reorganization  within the
meaning of section 368(a)(1)(C) of the Internal Revenue Code of 1986, as amended
(the "Code"). If the Reorganization  constitutes a tax-free  reorganization,  no
gain or loss will be recognized by the Tax Exempt Fund or its  shareholders as a
result of the  Reorganization.  See "Information  About The Reorganization - Tax
Considerations."

                  INVESTMENT PRACTICES AND RISK CONSIDERATIONS

         The investment  objectives,  policies and restrictions of the Municipal
Bond Fund and the Tax Exempt Fund are substantially similar,  although the Funds
differ to some extent  with  respect to  particular  investment  techniques  and
instruments,  as described  below.  Because the Funds share  similar  investment
objectives and policies, PIMS and MMS believe that the risks of investing in the
Municipal Bond Fund are  substantially  similar to the risks of investing in the
Tax Exempt Fund. The investment  objectives,  policies and  restrictions  of the
Funds,  and certain  differences  between them, are discussed  below. For a more
detailed  description,  please see the  prospectus  and  statement of additional
information  describing  each Fund.  There can be no assurance  that either Fund
will achieve its stated objective(s).
<PAGE>

Comparison of Objectives and Primary Investments

         The primary investment  objective for each Fund is to seek high current
income exempt from federal income tax,  consistent with preservation of capital.
For the Municipal  Bond Fund,  capital  appreciation  is a secondary  investment
objective.  The Funds seek  their  objectives  by  investing  primarily  in debt
securities  whose  interest is, in the opinion of bond counsel for the issuer at
the time of  issuance,  exempt  from  federal  income tax  ("Municipal  Bonds").
Municipal Bonds  generally are issued by states and local  governments and their
agencies,  authorities and other instrumentalities.  It is a policy of each Fund
that,  under normal  market  conditions,  at least 80% of its net assets will be
invested in Municipal Bonds.
   
         The Municipal  Bond Fund may invest up to 10% of its net assets,  under
normal market  conditions,  in Municipal Bonds or "private activity" bonds which
are rated below Baa by Moody's  Investors  Service,  Inc.  ("Moody's") or BBB by
Standard & Poor's  Ratings  Services  ("S&P") but which are rated at least Ba by
Moody's  or  BB by  S&P  (or,  if  unrated,  determined  by  Pacific  Investment
Management to be of comparable quality). The remaining 90% of the Municipal Bond
Fund's portfolio will be invested in "investment grade" securities.  For the Tax
Exempt Fund, the 80% component of its portfolio invested in Municipal Bonds must
consist of "investment  grade" Municipal Bonds.  Securities are considered to be
investment  grade if they are rated at least Baa by Moody's or BBB by S&P or, if
they  are  unrated,  determined  by  the  Fund's  investment  adviser  to  be of
comparable  quality.  The Tax Exempt Fund may invest up to 20% of its net assets
in  Municipal  Bonds or  "private  activity"  bonds which are rated below Baa by
Moody's  or BBB by S&P but which are rated at least Ba by  Moody's  or BB by S&P
(or, if unrated,  determined by Columbus  Circle to be of  comparable  quality).
Securities  rated  lower  than  Baa by  Moody's  or  lower  than  BBB by S&P are
sometimes  referred to as "high yield" or "junk" bonds.  For  information on the
risks associated with  investments in securities  rated below investment  grade,
see "Comparison of Securities and Investment  Techniques  High Yield  Securities
("Junk  Bonds")"  below  and   "Characteristics  and  Risks  of  Securities  and
Investment Techniques--High Yield Securities ("Junk Bonds")" in Appendix B.
    
         Under normal circumstances, the average portfolio duration of each Fund
will vary within a three- to ten-year  time frame,  based on Pacific  Investment
Management's  or  Columbus  Circle's  forecast  for  interest  rates.  For  more
information regarding duration, see "Description of Duration" in Appendix B.

         The Municipal  Bond Fund may invest up to 20% of its net assets in U.S.
Government  securities,  money market  instruments,  "private activity" bonds or
other  securities that are described below.  Similarly,  the Tax Exempt Fund may
invest  up to 20% of its  net  assets  in any  combination  of  those  types  of
securities.  For  temporary  defensive  purposes,  each Fund may invest all or a
portion of its assets in U.S.  Government  securities.  The Tax Exempt  Fund may
also  invest  up to 100% of its  assets  in  non-U.S.  Government  money  market
instruments for temporary defensive purposes.
<PAGE>

         Because the Municipal Bond Fund has capital appreciation as a secondary
investment  objective,  a  greater  percentage  of  the  Municipal  Bond  Fund's
distributions  may be derived from taxable  capital  gains than is generally the
case with the Tax Exempt Fund. For more information, see "Taxes" in Appendix B.

         Fundamental Policies. The Municipal Bond Fund's investment objective is
fundamental  and may be changed  only with the  approval  of a  majority  of the
shareholders  of the  Fund.  The  Tax  Exempt  Fund's  investment  objective  is
nonfundamental  and may be changed by the  Trustees of MMS  without  shareholder
approval.  For each Fund, all other policies  described above are nonfundamental
and may be changed by its Board of Trustees without shareholder approval.

         Investment Restrictions. Each Fund has adopted "fundamental" investment
restrictions   that  may  be  changed   only  with   shareholder   approval  and
"nonfundamental"  investment  restrictions  that may be  changed  by the  Fund's
Trustees without shareholder approval.  While the investment restrictions of the
Tax Exempt Fund are similar to the investment restrictions of the Municipal Bond
Fund, there are certain differences, which are discussed below.

         As a fundamental restriction, the Municipal Bond Fund may borrow money,
or pledge,  mortgage or  hypothecate  its assets,  if there is asset coverage of
300%.  However,  as an operating policy, the Municipal Bond Fund will not borrow
money, except for temporary administrative purposes. The Tax Exempt Fund may not
borrow money, or pledge, mortgage or hypothecate its assets, in excess of 10% of
the value of the Fund's  total assets at the time of  borrowing.  The Tax Exempt
Fund may borrow only from banks as a temporary measure to facilitate the meeting
of redemption requests or for extraordinary or emergency purposes.
   
    
         As a  nonfundamental  restriction,  the Tax  Exempt  Fund may not write
(sell) options.  In addition,  that Fund may not purchase put or call options if
the premiums paid by the Fund on all outstanding options exceeds 5% of its total
assets. The Municipal Bond Fund does not have such  restrictions.  The Municipal
Bond Fund may not invest  more than 5% of its assets  (taken at market  value at
the time of investment) in any combination of interest only,  principal only, or
inverse floating rate securities.  The Tax Exempt Fund has no such  restriction.
Neither  Fund may invest more than 15% of its net assets in any  combination  of
illiquid securities.

Comparison of Securities and Investment Techniques

         The  following  is a summary  of the types of  securities  in which the
Funds  may  invest  and  strategies  the Funds may  employ in  pursuit  of their
investment  objectives,  and certain risks associated with those investments and
techniques. While the securities and investment techniques used by the Funds are
similar,  there are some differences.  As with any security,  an investment in a
Fund's  shares  involves  certain  risks,  including  the  potential for loss of
principal.  The Funds are  subject to  varying  degrees  of  financial,  market,
interest  and credit  risks.  For a further  discussion  of the  securities  and
investment  techniques used by the Municipal Bond Fund, and the risks associated
therewith,  see  "Appendix   B--Characteristics  and  Risks  of  Securities  and
Investment Techniques."
<PAGE>

         Municipal  Bonds.  Both  Funds  invest  in  Municipal  Bonds  which are
generally issued by states and local governments and their agencies, authorities
and other  instrumentalities.  The Municipal  Bonds which the Funds may purchase
include  general  obligation  bonds and  limited  obligation  bonds (or  revenue
bonds), including industrial development bonds issued pursuant to former federal
tax law.  General  obligation  bonds are obligations  involving the credit of an
issuer  possessing  taxing  power and are  payable  from that  issuer's  general
revenues  and not from any  particular  source.  Limited  obligation  bonds  are
payable  only from the revenues  derived from a particular  facility or class of
facilities  or, in some cases,  from the  proceeds of a special  excise or other
specific  revenue  source.  Tax-exempt  "private  activity" bonds and industrial
development bonds generally are also revenue bonds and thus are not payable from
the issuer's general revenues.

         Municipal  Bonds are  subject to credit and market  risk.  Credit  risk
relates to the ability of the issuer to make payments of principal and interest.
The ability of an issuer to make such payments  could be affected by litigation,
legislation or other  political  events or the bankruptcy of the issuer.  Market
risk relates to changes in a security's value as a result of changes in interest
rates.  Lower rated  Municipal  Bonds  generally  provide  higher yields but are
subject to greater credit and market risk than higher quality  Municipal  Bonds.
The  secondary  market for Municipal  Bonds  typically has been less liquid than
that for  taxable  debt/fixed  income  securities,  and this may affect a Fund's
ability  to sell  particular  Municipal  Bonds at  then-current  market  prices,
especially  in periods  when other  investors  are  attempting  to sell the same
securities.

         The Municipal Bond Fund may invest in municipal  lease  obligations.  A
lease is not a full  faith and  credit  obligation  of the issuer and is usually
backed  only by the  borrowing  government's  unsecured  pledge  to make  annual
appropriations  for lease  payments.  The Municipal Bond Fund may also invest in
municipal  warrants.  Like options,  warrants may expire  worthless and they may
have reduced liquidity.  The Municipal Bond Fund will not invest more than 5% of
its net assets in municipal  warrants.  The Municipal Bond Fund also may seek to
enhance its yield  through the  purchase of private  placements,  which may have
resale restrictions.

         The  Municipal  Bond Fund may invest in  Municipal  Bonds  with  credit
enhancements  such as letters of credit,  municipal  bond  insurance and Standby
Bond Purchase  Agreements  ("SBPA").  The Municipal Bond Fund may also invest in
Residual  Interest  Bonds,  which are  created by  dividing  the  income  stream
provided by an underlying bond to create two securities,  one short term and one
long term.  Rising  short-term  interest  rates  result in lower  income for the
longer-term  portion, and vice versa. The longer-term bonds can be very volatile
and may be less liquid than other  Municipal Bonds of comparable  maturity.  The
Municipal  Bond  Fund  will not  invest  more  than 10% of its  total  assets in
Residual Interest Bonds.
<PAGE>

         The  Municipal  Bond  Fund  may  invest  in  participation   interests.
Participation  interests are various  types of securities  created by converting
fixed  rate bonds  into  short-term,  variable  rate  certificates.  There is no
guarantee  the interest  thereon will be exempt from federal  taxes  because the
Internal Revenue Service has not issued a definitive ruling on the matter.

         Each Fund may, subject to restrictions  imposed by the Code,  invest up
to 20% of its net assets in some or all of the following types of securities and
investment techniques.

         U.S. Government Securities.  U.S. Government securities are obligations
of and, in certain cases,  guaranteed by, the U.S.  Government,  its agencies or
instrumentalities. The U.S. Government does not guarantee the net asset value of
the  Funds'  shares.  U.S.   Government   securities  may  include  zero  coupon
securities,  which do not distribute  interest on a current basis and tend to be
subject  to  greater  market  risk than  interest-paying  securities  of similar
maturities.

         Variable  And Floating  Rate  Securities.  Variable  and floating  rate
securities  provide for a periodic  adjustment  in the interest rate paid on the
obligations.

         Inflation-Indexed   Bonds.  The  Municipal  Bond  Fund  may  invest  in
inflation-indexed bonds, which are fixed income securities whose principal value
is  periodically  adjusted  according  to the  rate  of  inflation.  Such  bonds
generally  are issued at an  interest  rate lower than  typical  bonds,  but are
expected to retain their  principal  value over time. The interest rate on these
bonds is fixed at issuance,  but over the life of the bond this  interest may be
paid on an increasing principal value, which has been adjusted for inflation. If
a guarantee of principal is not provided,  the adjusted  principal  value of the
bond repaid at maturity  may be less than the  original  principal.  While these
securities  are expected to be protected  from  long-term  inflationary  trends,
short-term increases in inflation may lead to a decline in value.

         High Yield  Securities  ("Junk  Bonds").  The  Municipal  Bond Fund may
invest up to 10% of its assets in securities  rated lower than Baa by Moody's or
BBB by S&P,  but rated at least Ba by  Moody's  or BB by S&P (or,  if not rated,
determined  to be of comparable  quality).  The Tax Exempt Fund may invest up to
20% of its assets in such securities. Securities rated lower than Baa by Moody's
or lower than BBB by S&P are  sometimes  referred  to as "high  yield" or "junk"
bonds.

         Investing in high yield  securities  involves special risks in addition
to  the  risks   associated  with  investments  in  higher  rated  fixed  income
securities.  High yield securities may be regarded as predominately  speculative
with respect to the issuer's  continuing  ability to meet principal and interest
payments.  For more  information,  see "Appendix B --  Description of Securities
Ratings." Analysis of the  creditworthiness  of issuers of high yield securities
may be more complex than for issuers of higher quality debt securities.

         High yield  securities  may be more  susceptible  to real or  perceived
adverse  economic  and  competitive   industry   conditions  than  higher  grade
securities.  The  prices of high  yield  securities  have been  found to be less
sensitive to interest rate changes than more highly rated investments,  but more
sensitive to adverse economic downturns or individual corporate developments. If
the  issuer of high  yield  securities  defaults,  a Fund may  incur  additional
expenses to seek recovery.
<PAGE>

         The secondary  markets on which high yield securities are traded may be
less liquid than the market for higher  grade  securities,  which may  adversely
affect and cause  large  fluctuations  in the daily net asset  value of a Fund's
shares.  Adverse  publicity  and investor  perceptions,  whether or not based on
fundamental  analysis,  may  decrease  the  values and  liquidity  of high yield
securities, especially in a thinly traded market.

         Pacific Investment  Management and Columbus Circle seek to minimize the
risks of investing in high yield securities  through  diversification,  in-depth
credit  analysis and  attention to current  developments  in interest  rates and
market conditions.

         Corporate  Debt  Securities.  Each Fund may  invest in  corporate  debt
securities. The rate of interest paid on a corporate debt security may be fixed,
floating or variable,  and may vary inversely with respect to a reference  rate.
See "Variable and Floating Rate Securities"  above. The rate of return or return
of principal on some debt  obligations  may be linked or indexed to the level of
exchange rates between the U.S. dollar and a foreign currency or currencies.

         Mortgage-Backed and Other Asset-Backed Securities. Each Fund may invest
in mortgage- or other  asset-backed  securities.  The value of some mortgage- or
asset-backed  securities in which the Funds invest may be particularly sensitive
to  changes  in  prevailing   interest  rates,  and,  like  other  fixed  income
investments,  the ability of a Fund to  successfully  use these  instruments may
depend in part upon the  ability of Pacific  Investment  Management  or Columbus
Circle to forecast interest rates and other economic factors correctly.

         Mortgage  Pass-Through  Securities  represent  interests  in "pools" of
mortgage  loans  secured by  residential  or  commercial  real  property.  Early
repayment of principal on some mortgage-related  securities may expose a Fund to
a lower rate of return upon  reinvestment of principal.  Like other fixed income
securities,  when interest rates rise, the value of a mortgage-related  security
generally will decline; however, when interest rates are declining, the value of
mortgage-related securities with prepayment features may not increase as much as
other fixed income securities.  The rate of prepayments on underlying  mortgages
will affect the price and  volatility of a  mortgage-related  security,  and may
have the  effect of  shortening  or  extending  the  effective  maturity  of the
security.

         Commercial  Mortgage-Backed  Securities include securities that reflect
an interest in, and are secured by,  mortgage loans on commercial real property.
Many of the risks of investing in commercial  mortgage-backed securities reflect
the risks of  investing  in the real estate  securing  the  underlying  mortgage
loans. These risks reflect the effects of local and other economic conditions on
real  estate  markets,  the  ability of tenants to make loan  payments,  and the
ability of a property to attract and retain tenants.  Commercial mortgage-backed
securities may be less liquid and exhibit  greater price  volatility  than other
types of mortgage-related or asset-backed securities.
<PAGE>

         Mortgage-Related   Securities   include  securities  other  than  those
described above that directly or indirectly represent a participation in, or are
secured by and payable from, mortgage loans on real property.

         Other   Asset-Backed   Securities   The  Funds  may   invest  in  other
asset-backed  securities  that have been or may be offered to  investors.  For a
discussion of the characteristics of some of these instruments, see Appendix B.

         Repurchase  Agreements.  For the purpose of achieving income, each Fund
may  enter  into  repurchase   agreements,   which  entail  the  purchase  of  a
portfolio-eligible  security  from  a  bank  or  broker-dealer  that  agrees  to
repurchase  the  security  at the Fund's cost plus  interest  within a specified
time. If the party agreeing to repurchase should default,  the Fund will seek to
sell the  securities  which it holds,  which could involve  procedural  costs or
delays in addition to a loss on the  securities if their value should fall below
their repurchase price.

         Reverse Repurchase Agreements,  Dollar Rolls, And Borrowings. A reverse
repurchase agreement involves the sale of a security by a Fund and its agreement
to repurchase the  instrument at a specified time and price.  The Municipal Bond
Fund may enter into dollar  rolls,  in which the Fund sells  mortgage-backed  or
other securities for delivery in the current month and simultaneously  contracts
to purchase  substantially  similar securities on a specified future date. Apart
from such  transactions,  the Municipal Bond Fund will not borrow money,  except
for temporary administrative purposes.

         Loans Of Portfolio Securities. For the purpose of achieving income, the
Municipal Bond Fund may lend its portfolio  securities to brokers,  dealers, and
other  financial  institutions,  subject to certain  provisions  described under
"Loans of Portfolio  Securities" in Appendix B. Securities  lending involves the
risk of loss of rights in the  collateral or delay in recovery of the collateral
should the borrower fail to return the  securities  loaned or become  insolvent.
The Tax Exempt Fund may lend its portfolio  securities  with respect to not more
than 25% of its total assets.

         When-Issued,  Delayed Delivery,  And Forward  Commitment  Transactions.
Each of the Funds may  purchase or sell  securities  on a  when-issued,  delayed
delivery,  or  forward  commitment  basis.  When  purchasing  a  security  on  a
when-issued,  delayed delivery,  or forward commitment basis, a Fund assumes the
rights and risks of ownership of the  security,  including the risk of price and
yield fluctuations. These risks are in addition to the risks associated with the
Fund's  other  investments.  When a Fund has sold a security  on a  when-issued,
delayed delivery,  or forward commitment basis, the Fund does not participate in
future  gains or losses with  respect to the  security.  If the other party to a
transaction  fails to deliver or pay for the  securities,  the Fund could miss a
favorable price or yield opportunity or could suffer a loss.

         Short Sales. Each Fund may from time to time effect short sales as part
of its overall portfolio  management  strategy,  including the use of derivative
instruments,  or to offset  potential  declines  in value of long  positions  in
similar  securities as those sold short.  To the extent that the Municipal  Bond
Fund engages in short sales, it must (except in the case of short sales "against
the box") maintain asset coverage in the form of assets  determined to be liquid
by Pacific  Investment  Management in accordance with procedures  established by
the Board of Trustees,  in a segregated account, or otherwise cover its position
in a  permissible  manner.  A short sale is "against the box" to the extent that
the Fund  contemporaneously  owns,  or has the right to obtain at no added cost,
securities  identical to, or convertible  into or  exchangeable  for, those sold
short. The Tax Exempt Fund may only make short sales "against the box."
<PAGE>

         Derivative  Instruments.  To the  extent  permitted  by the  investment
objectives and policies of the Funds,  the Funds may purchase and write call and
put options, enter into futures contracts, and use options on futures contracts.
The Funds may use these techniques to hedge against changes in interest rates or
securities prices or as part of their overall investment strategies.

         The use of these strategies involves certain special risks, including a
possible imperfect correlation, or even no correlation,  between price movements
of derivative instruments and price movements of related investments. While some
strategies  involving  derivative  instruments 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 related  investments  or  otherwise,  due to the
possible  inability of a Fund to purchase or sell a portfolio security at a time
that  otherwise  would be  favorable  or the  possible  need to sell a portfolio
security  at a  disadvantageous  time  because  the Fund is required to maintain
asset coverage or offsetting positions,  and the possible inability of a Fund to
close out or to liquidate its derivatives positions.

         The value of some derivative  instruments in which the Funds invest may
be particularly sensitive to changes in prevailing interest rates, and, like the
other  investments of the Funds, the ability of a Fund to successfully use these
instruments  may depend in part upon the  ability of the  investment  adviser to
forecast interest rates and other economic factors correctly.  If the investment
adviser incorrectly forecasts such factors and has taken positions in derivative
instruments contrary to prevailing market trends, a Fund could be exposed to the
risk of loss.

         Hybrid  Instruments.  The  Municipal  Bond  Fund may  invest  in hybrid
instruments.  A hybrid  instrument is a debt  instrument  the return of which is
calculated  with  reference  to a  securities  index,  commodity  index or other
financial index, and it can combine the characteristics of securities,  futures,
and options.  The value of a hybrid or its interest  rate may be a multiple of a
benchmark and, as a result,  may be leveraged and move (up or down) more steeply
and rapidly than the  benchmark.  These  benchmarks may be sensitive to economic
and  political  events.  The  purchase of hybrids  also  exposes the Fund to the
credit risk of the issuer of the hybrids.
   
         Investment In Other Investment  Companies.  The Municipal Bond Fund may
invest  in  securities  of  other  investment  companies,   such  as  closed-end
management  investment  companies,  or in pooled  accounts  or other  investment
vehicles.  As a shareholder  of an investment  company,  the Municipal Bond Fund
will  indirectly  bear  service and other fees which are in addition to the fees
the Fund pays its service providers.
    
<PAGE>

         Illiquid  Securities.  Each Fund may invest up to 15% of its net assets
in illiquid securities. A Fund may be subject to significant delays in disposing
of illiquid  securities,  and  transactions  in illiquid  securities  may entail
registration expenses and other transaction costs that are higher than those for
transactions  in liquid  securities.  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.

                                FEES AND EXPENSES

         Both  Funds  feature a  "unified"  fee  structure.  Each Fund has fixed
advisory and  administrative  fee rates. The administrative fee is all-inclusive
(with the  exception  of  advisory  fees) and covers the cost of  administrative
expenses such as legal,  audit,  custody,  transfer  agency,  printing and other
services reasonably  necessary for the ordinary operations of the Funds. Certain
other miscellaneous expenses are paid by the Funds.

         The  Municipal  Bond Fund's  investment  adviser is Pacific  Investment
Management,  a Delaware general partnership located at 840 Newport Center Drive,
Newport Beach,  California 92660. Pacific Investment  Management is a subsidiary
partnership of PIMCO Advisors.  The Trust, on behalf of the Municipal Bond Fund,
pays Pacific Investment  Management an investment advisory fee at an annual rate
of .25% of the average daily net assets of the Fund. These fees are computed and
accrued daily and paid monthly.
   
         The Tax Exempt Fund retains PIMCO Advisors as its  investment  adviser.
PIMCO Advisors  employs  Columbus Circle as Portfolio  Manager of the Tax Exempt
Fund.  Columbus  Circle  is a  subsidiary  partnership  of PIMCO  Advisors.  The
investment  advisory  fee for Tax Exempt Fund is equal to an annual rate of .30%
of the Fund's  average  daily net assets.  These fees are  computed  and accrued
daily and paid  monthly.  As of April 6,  1998,  Tax  Exempt  Fund had total net
assets of  $48,481,567.02.  The total  investment  advisory fees paid by the Tax
Exempt  Fund to PIMCO  Advisors  for the fiscal  year  ended June 30,  1997 were
approximately $166,000.
    
         The  Shareholder  Transaction  Expenses  for each  Fund,  and pro forma
expenses giving effect to the proposed Reorganization, are outlined in the table

         The current expenses of each Fund, and pro forma expenses giving effect
to  the  proposed  Reorganization,  are  outlined  below.  The  expenses  of the
Municipal Bond Fund are based upon the estimated annual  operating  expenses for
the  Class A,  Class B and  Class C shares  of the  Municipal  Bond Fund for the
current  fiscal year.  The pro forma  expenses also are based upon the estimated
annual  operating  expenses of the  Municipal  Bond Fund for the current  fiscal
year.

                  servicing   fees  which  are  paid  annually  to  PIMCO  Funds
                  Distributors   LLC   (the   "Distributor")   and   repaid   to
                  participating  brokers,  certain  banks  and  other  financial
                  intermediaries.   12b-1  fees  which  exceed  .25%   represent
                  aggregate  distribution  and servicing fees. See  "Distributor
                  and Distribution and Servicing Plans" in Appendix B.
   
                  2. The Distributor  has  voluntarily  undertaken to reduce the
                  12b-1 fee it may receive with respect to Class C shares of the
                  Municipal  Bond Fund to .75% of the Fund's  average  daily net
                  assets attributable to Class C shares until further notice.

                  3. Absent the  undertaking  noted,  the "Total Fund  Operating
                  Expenses" for Class C shares of the Municipal  Bond Fund would
                  be 1.60% of average daily net assets  attributable  to Class C
                  shares.
    
         The  purpose  of  the  foregoing  tables  is  to  assist  investors  in
understanding  the  various  costs  and  expenses  that are  borne  directly  or
indirectly  by Class A,  Class B and  Class C  shareholders  of the  Funds.  The
Examples for Class A shares  assume  payment of the current  maximum  applicable
sales  load.  Due to the 12b-1  distribution  fee imposed on Class B and Class C
shares,  a Class B or Class C  shareholder  of the Funds may,  depending  on the
length of time the shares are held, pay more than the economic equivalent of the
maximum  front-end  sales  charges  permitted by relevant  rules of the National
Association of Securities Dealers, Inc.

                      INFORMATION ABOUT THE REORGANIZATION.

         The  Reorganization  Agreement.  As stated  above,  the  Reorganization
Agreement  provides  for  the  transfer  of  all of the  assets  and  all of the
liabilities  of the Tax Exempt Fund to the  Municipal  Bond Fund in exchange for
that  number of full and  fractional  Class A, Class B and Class C shares in the
Municipal  Bond Fund having an aggregate  net asset value equal to the aggregate
net  asset  value of the Class A,  Class B and Class C shares of the Tax  Exempt
Fund as of the close of business on the Exchange  Date. In  connection  with the
Reorganization,  the Tax Exempt Fund will  distribute  the shares of  beneficial
interest of the Municipal Bond Fund received in the exchange to the shareholders
of the Tax Exempt Fund in complete liquidation of the Tax Exempt Fund.

         Upon  completion of the  Reorganization,  each  shareholder  of the Tax
Exempt Fund will own that number of full and fractional  Class A, Class B and/or
Class C shares in the  Municipal  Bond Fund having an aggregate  net asset value
equal to the aggregate net asset value of each respective class of shares in the
Tax Exempt  Fund held by that  shareholder  as of the close of  business  on the
Exchange  Date.  In the  interest  of  economy  and  convenience,  shares of the
Municipal Bond Fund generally will not be represented by physical certificates.

         Until the  Exchange  Date,  shareholders  of the Tax  Exempt  Fund will
continue to be able to redeem their shares.  Redemption  requests received after
the  Exchange  Date  will be  treated  as  requests  received  by  PIMS  for the
redemption  of Municipal  Bond Fund shares  received by the  shareholder  in the
Reorganization.

         The obligations of MMS and PIMS under the Reorganization  Agreement are
subject to various  conditions,  as stated  therein.  Among  other  things,  the
Reorganization  requires  that all filings be made with,  and all  authority  be
received from, the SEC and state  securities  commissions as may be necessary in
the  opinion  of counsel  to permit  the  parties to carry out the  transactions
contemplated by the Reorganization Agreement. MMS and PIMS are in the process of
making the necessary filings. The Reorganization  Agreement may be terminated at
any time by action of the Trustees of MMS and the Trustees of PIMS. MMS or PIMS,
after  consultation  with  counsel and by consent of its  Trustees or an officer
authorized by its Trustees,  may at any time waive compliance with any condition
contained in the  Reorganization  Agreement.  For a complete  description of the
terms and conditions of the Reorganization,  see the Reorganization Agreement at
Appendix A. If the  transaction  is not  completed  by December  31,  1998,  the
Reorganization  Agreement  will  automatically  terminate  on that date unless a
later date is agreed upon by the Funds.
   
         Tax  Considerations.  The  Reorganization  is  intended  to qualify for
federal  income  tax  purposes  as  a  tax-free   reorganization  under  Section
368(a)(1)(C) of the Code. Accordingly,  pursuant to this treatment,  neither the
Tax Exempt Fund nor the  Municipal  Bond Fund are expected to recognize any gain
or loss for  federal  income tax  purposes  from the  transfer of the Tax Exempt
Fund's assets to the Municipal Bond Fund. As a condition to the  Reorganization,
the Funds will  receive an opinion  from  counsel to MMS to the effect  that the
Reorganization will qualify as a tax-free  reorganization for federal income tax
purposes.  That opinion will be based in part upon certain  assumptions and upon
certain representations made by the Funds.
    
<PAGE>

         Application for Exemptive Relief.  PIMS and MMS have sought an order of
exemption  from the SEC in  connection  with the  proposed  transfer  of  assets
contemplated by the Reorganization. Such order has been requested due to Pacific
Investment  Management's  ownership  of  shares of the  Municipal  Bond Fund and
certain  affiliations  that  may  exist  among  the  Funds,  Pacific  Investment
Management and PIMCO Advisors. On the basis of relevant precedent,  PIMS and MMS
anticipate  that  the SEC  will  issue  the  requested  order,  but  there is no
certainty that the SEC will issue the order, or that the order will be necessary
for the successful completion of the proposed Reorganization.
   
         Expenses of the  Reorganization.  The expenses relating to the proposed
Reorganization  incurred by the Tax Exempt Fund,  including expenses incurred in
connection with this Notice and Proxy Statement/Prospectus and the meeting, will
be borne by the Tax  Exempt  Fund up to  $24,241.  This  amount  was  determined
pursuant to the following  formula  approved by the MMS Trustees:  the lesser of
(i) six months of the projected  savings to the Tax Exempt Fund shareholders due
to the lower operating expenses of the Municipal Bond Fund (based upon the value
of the Tax Exempt Fund on the Record Date, as described below), or (ii) $25,000.
PIMCO  Advisors  will bear the  expenses of the  Reorganization  that exceed the
amount paid by the Tax Exempt Fund. The expenses relating to the  Reorganization
incurred by the Municipal Bond Fund will be borne by PIMCO Advisors.
    
         Reasons  for  the  Reorganization.   The  proposed  Reorganization  was
presented  to the Board of Trustees of MMS for  consideration  and approval at a
meeting of the Board held on March 5, 1998. For the reasons discussed below, the
Board of Trustees of MMS,  including all of the Independent  Trustees present at
the meeting, determined that the interests of the shareholders of the Tax Exempt
Fund will not be diluted as a result of the  proposed  Reorganization,  and that
the proposed  Reorganization is in the best interests of the Tax Exempt Fund and
its shareholders.
   
         The Trustees were advised at the meeting that PIMCO Advisors is seeking
to  centralize  its  fixed  income  advisory  business  in  Pacific   Investment
Management.  Currently,  the Tax Exempt Fund is the only remaining  fixed income
account  that is advised by  Columbus  Circle,  which is winding  down its fixed
income  business.  Pacific  Investment  Management  has  long  contemplated  the
creation of a tax exempt series of PIMS,  which recently was accomplished by the
creation  of the  Municipal  Bond  Fund.  PIMS is a  multi-portfolio  investment
company  that has over $27  billion  invested  pursuant to a wide range of fixed
income investment  strategies.  Pacific Investment  Management had approximately
$118 billion under  management as of December 31, 1997,  almost  exclusively  in
fixed income portfolios.
    
<PAGE>

         The Trustees  believe that the proposed  combination  of the Tax Exempt
Fund and the Municipal  Bond Fund will allow the Tax Exempt Fund's  shareholders
to continue to  participate in a  professionally  managed  portfolio  consisting
primarily of Municipal Bonds, and that Tax Exempt Fund shareholders will benefit
from  Pacific  Investment  Management's  substantial  expertise  in fixed income
investing and the Municipal Bond Fund's lower total fund operating  expenses and
lower investment management fees, as shown in "Fees and Expenses" above.

         ACCORDINGLY,  THE TRUSTEES OF MMS,  INCLUDING THE INDEPENDENT  TRUSTEES
PRESENT  AT THE MARCH 5, 1998  MEETING,  RECOMMEND  THAT THE TAX  EXEMPT  FUND'S
SHAREHOLDERS APPROVE THE REORGANIZATION WITH THE MUNICIPAL BOND FUND.

         The Board of Trustees of MMS, in recommending the proposed transaction,
considered a number of factors, including the following:

          (1)     expense ratios and information  regarding fees and expenses of
                  the Tax Exempt Fund and the Municipal Bond Fund;

          (2)     the terms and  conditions of the  Reorganization,  whether the
                  Reorganization  is in the  best  interests  of the Tax  Exempt
                  Fund,  and  whether  it  would  result  in a  dilution  of the
                  interests of the Tax Exempt Fund's shareholders at the time of
                  the Reorganization;

          (3)     the  compatibility  of the  Municipal  Bond Fund's  investment
                  objectives,  policies and  restrictions  with those of the Tax
                  Exempt Fund;

          (4)     the expertise of Pacific Investment Management in fixed income
                  investing;

          (5)     the   capabilities   and   resources  of  Pacific   Investment
                  Management  and its  affiliates  in the  areas  of  investment
                  management and shareholder servicing;

          (6)     the   growth   opportunities    afforded   by   the   proposed
                  consolidation  with the Municipal Bond Fund, which is a series
                  of a much  larger  investment  company  complex  than MMS that
                  focuses on fixed income investments;

          (7)     the tax consequences to the Tax Exempt Fund and its
                  shareholders; and

          (8)     the direct and indirect costs to be incurred by the Tax Exempt
                  Fund   and   its   shareholders   in   connection   with   the
                  Reorganization.

         Certain Payments by Distributor. In connection with the sale of Class B
and Class C shares of the Tax Exempt  Fund,  PIMCO Funds  Distributors  LLC (the
"Distributor"),  the principal  underwriter of MMS and PIMS, pays commissions to
broker-dealers  from its own assets that it expects to recover over time through
the receipt of distribution fees in connection with the Fund's Class B and Class
C shares and the receipt of any contingent deferred sales charges on Class B and
Class C shares.  The total amount of such  commissions  paid by the  Distributor
with  respect to the Tax Exempt Fund  before the  consummation  of the  proposed
Reorganization  will likely exceed the amounts  recovered by the  Distributor by
that time.  Such  unrecovered  amounts do not  represent a liability  of the Tax
Exempt Fund and, consequently,  the Municipal Bond Fund will not assume any such
liability in connection with the consummation of the Reorganization. However, to
the extent the Distributor has not fully recovered such  commissions  before the
consummation  of the proposed  Reorganization,  it is anticipated  that the PIMS
Trustees  will  consider  such  unrecovered  amounts,  among other  factors,  in
determining whether to continue payments of distribution fees in the future with
respect to Class B and Class C shares of the Municipal Bond Fund.

                     ADDITIONAL INFORMATION ABOUT THE FUNDS

         Form of Organization.  The Municipal Bond Fund is a diversified  series
of PIMS, an open-end management  investment company organized as a Massachusetts
business trust on February 19, 1987 and registered under the Investment  Company
Act of 1940 (the "1940 Act"). PIMS offers other series of shares,  which are not
involved in the  Reorganization.  The Tax Exempt Fund is a diversified series of
MMS, an open-end  management  investment  company  organized as a  Massachusetts
business  trust on August 24, 1990 and  registered  under the 1940 Act. MMS also
offers other series of shares, which are not involved in the Reorganization.

         PIMS and MMS are each governed by a separate  Agreement and Declaration
of Trust (in the case of MMS) and Declaration of Trust (in the case of PIMS), as
amended or restated from time to time.  While the PIMS  Declaration of Trust and
the MMS Agreement and  Declaration  of Trust are  different,  they are generally
comparable in all material  respects.  The business and affairs of each Fund are
managed under the  direction of a Board of Trustees.  The  respective  Boards of
Trustees of the Funds have no members in common.

         Description of Securities To Be Issued. The number of authorized shares
of  beneficial  interest  of each  of  PIMS  and  MMS is  unlimited.  Under  the
Declaration of Trust of PIMS and the Agreement and  Declaration of Trust of MMS,
the Board of Trustees  is  authorized  to create new series of shares  without a
vote of  shareholders.  Interests in the Municipal  Bond Fund and the Tax Exempt
Fund are represented by transferable  shares of beneficial interest having a par
value of $0.0001 and $0.00001,  respectively.  The Trustees of PIMS and MMS each
have the power to create  separate  classes  of shares  for each  series  and to
create additional classes in the future without a vote of shareholders. Although
shareholders of different classes of a series would have an interest in the same
portfolio  of assets,  shareholders  of  different  classes  may bear  different
expenses, which may affect performance.

         Voting Rights. Shares of PIMS and MMS entitle their holders to one vote
per  share;  however,  separate  votes  will be taken by each  series on matters
affecting an individual series.  Shares have noncumulative  voting rights and no
preemptive  or  subscription  rights.  PIMS  and MMS are  not  required  to hold
shareholder  meetings annually,  although shareholder meetings may be called for
purposes such as electing or removing Trustees, changing fundamental policies or
approving an investment advisory agreement.

         Dividends  and  Other  Distributions.  For  each  Fund,  dividends  are
declared daily from net investment  income and paid monthly to  shareholders  of
record. Due to its secondary  investment  objective of capital  appreciation,  a
greater  percentage of the Municipal  Bond Fund's  distributions  may be derived
from taxable capital gains than is generally the case with the Tax Exempt Fund.
<PAGE>

         Dividend and capital gain distributions of the Municipal Bond Fund will
be reinvested in additional shares of the Fund unless the shareholder  elects to
have them paid in cash. There are no sales charges on reinvested dividends. If a
shareholder has elected to receive  dividends and/or capital gain  distributions
in cash and the postal or other delivery  service is unable to deliver checks to
the  shareholder's  address  of record,  the  shareholder's  distributions  will
automatically  be invested in the PIMCO Money Market Fund until the  shareholder
is located.  Dividends  from net  investment  income with respect to Class B and
Class C shares are  expected to be lower than those paid with respect to Class A
shares as a result of the distribution fees applicable to Class B and C shares.

         Shareholders may elect to invest dividends and/or distributions paid by
the Municipal  Bond Fund in shares of the same class of any other series of PIMS
at net asset value.  The shareholder  must have an account  existing in the Fund
selected for investment with the identical  registered name and address and must
elect  this  option on the  account  application,  on a form  provided  for that
purpose or by a telephone request to PIMS's transfer agent at 800-426-0107.

         If the  Reorganization  Agreement is approved by the Tax Exempt  Fund's
shareholders,  then as soon as  practicable  before the Exchange  Date,  the Tax
Exempt Fund will pay its shareholders a cash  distribution of all  undistributed
1998 net investment income and undistributed realized net capital gains.

         Dividends  designated by the Tax Exempt Fund as capital gain  dividends
derived from the Tax Exempt  Fund's net capital gain (that is, the excess of net
long-term  gain  over net  short-term  loss)  are  taxable  to  shareholders  as
long-term capital gain except as provided by an applicable tax exemption.  Under
the Taxpayer Relief Act of 1997, long-term capital gains will generally be taxed
at a 28% or 20%  rate,  depending  upon  the  holding  period  of the  portfolio
securities.  Any  distributions  that  are not from the Tax  Exempt  Fund's  net
investment  income,  short-term  capital  gain,  or  net  capital  gain  may  be
characterized  as a return of  capital to  shareholders  or, in some  cases,  as
capital  gain.  For  state  income  tax  purposes,   interest  on  some  federal
obligations generally is not exempt from taxation,  whether received directly by
a shareholder or through distributions of investment company taxable income (for
example,  interest  on Federal  National  Mortgage  Association  and  Government
National  Mortgage  Association  Certificates).  The Tax Exempt Fund will advise
shareholders of the amount and nature of the dividends paid to them.

         Dividends paid to shareholders by the Tax Exempt Fund which are derived
from interest on Municipal Bonds are expected to be designated by the Tax Exempt
Fund as "exempt-interest dividends," and shareholders may generally exclude such
dividends  from gross  income for federal  income tax  purposes.  However,  if a
shareholder  receives  social  security or  railroad  retirement  benefits,  the
shareholder may be taxed on a portion of those benefits as a result of receiving
tax-exempt  income.  In addition,  certain  exempt-interest  dividends could, as
discussed below, cause certain shareholders to become subject to the alternative
minimum  tax  and  may  increase  the  alternative   minimum  tax  liability  of
shareholders already subject to this tax.
<PAGE>

         To the extent that  dividends  paid to  shareholders  by the Tax Exempt
Fund are derived from taxable  interest or from capital  gains,  such  dividends
will be subject to federal  income tax.  Any gain  realized on a  redemption  of
shares will be taxable  gain,  subject to any  applicable  tax and exemption for
which an investor may qualify.

actual  capitalization  of the Tax Exempt Fund and the Municipal Bond Fund as of
March 31,  1998,  and the  capitalization  on a pro forma  basis as of that date

                               GENERAL INFORMATION

Solicitation of Proxies

         Solicitation  of proxies is being made primarily by the mailing of this
Notice and Proxy  Statement/Prospectus  on or about April __, 1998. Shareholders
of the Tax Exempt Fund whose shares are held by nominees,  such as brokers,  can
vote their proxies by contacting  their respective  nominee.  In addition to the
solicitation  of proxies by mail,  proxies  also may be solicited by officers or
agents  of MMS  and  employees  of  PIMCO  Advisors  and its  affiliates,  or by
professional  proxy  solicitation  firms  retained by PIMCO  Advisors or Pacific
Investment Management.  As the meeting date approaches,  certain shareholders of
the Tax Exempt Fund may receive a telephone call asking the shareholder to vote.
The costs associated with any professional  proxy solicitation firm will be paid
by PIMCO Advisors or the Tax Exempt Fund, as described above under  "INFORMATION
ABOUT THE REORGANIZATION - Expenses of the Reorganization."

         A shareholder  may revoke the  accompanying  proxy at any time prior to
its use by filing with MMS a written revocation or a duly executed proxy bearing
a later date. In addition, any shareholder who attends the meeting in person may
vote by ballot at the meeting,  thereby  canceling any proxy  previously  given.
However,  attendance  at the  meeting,  by  itself,  will not  serve to revoke a
previously tendered proxy.
<PAGE>

         The persons  named in the  accompanying  proxy will vote as directed by
the proxy,  but in the absence of voting  directions in any proxy that is signed
and  returned,  they  intend  to vote  FOR the  proposal  and may  vote in their
discretion  with respect to other matters not now known to the Board of Trustees
of MMS that may be presented at the meeting.

Voting Rights

         The proposals in this proxy statement  affect only the Tax Exempt Fund,
which is one of 22 operating  series of MMS. As a result,  the Board of Trustees
of MMS is soliciting votes only from shareholders of the Tax Exempt Fund.
   
         Each share of the Tax Exempt Fund is entitled to one vote. Shareholders
of the Tax Exempt Fund at the close of  business  on April 6, 1998 (the  "Record
Date") will be entitled to be present and give voting  instructions  for the Tax
Exempt Fund at the meeting  with  respect to their shares owned as of the Record
Date. There were  3,964,151.682  shares of beneficial  interest  outstanding and
entitled  to vote as of the  Record  Date,  representing  total  net  assets  of
$48,481,567.02. Approval of the Reorganization requires a vote of a plurality of
the shares of the Tax Exempt Fund present and voting at the meeting.
    
         Thirty percent of the shares of the Tax Exempt Fund entitled to vote at
the meeting,  represented in person or by proxy, must be present to constitute a
quorum for the transaction of the Tax Exempt Fund's business at the meeting.  If
a quorum is not present at the meeting, or if a quorum is present but sufficient
votes to approve the proposal are not received, the persons named as proxies may
propose one or more  adjournments of the meeting to permit further  solicitation
of proxies.  Any adjournment will require the affirmative vote of a plurality of
those shares represented at the meeting in person or by proxy.  Unless otherwise
instructed,  the  persons  named as  proxies  will vote  proxies in favor of the
adjournment.  If the meeting is adjourned with respect to a proposal,  any other
proposal(s) may still be acted upon.

         If a  shareholder  abstains  from  voting,  or if a  broker  returns  a
"non-vote" proxy, indicating a lack of authority to vote, the shares represented
by the abstention or non-vote will be deemed present at the meeting for purposes
of determining a quorum.  However,  abstentions and broker non-votes will not be
deemed  represented at the meeting for purposes of  calculating  the vote on the
proposal.  As a result,  so long as a quorum is present,  abstentions and broker
non-votes will have no effect on the outcome of the proposal.

*   Entity owned 25% or more of the outstanding shares of beneficial interest of
    the  Municipal  Bond Fund,  and  therefore  may be presumed to "control" the
    Municipal Bond Fund, as that term is defined in the 1940 Act.

         On the basis of the holdings and commitments as of the Record Date, the
percentages on the foregoing table are not expected to change as a result of the
Reorganization, because the Municipal Bond Fund had outstanding as of the Record
Date only  Institutional  Class  shares and the Tax Exempt Fund had  outstanding
only Class A, Class B and Class C shares.  However,  the Municipal Bond Fund now
offers Class A, Class B and Class C shares, and the percentages appearing in the
foregoing table may change prior to the Reorganization.

         To the knowledge of each Fund, as of April 6, 1998, no current  Trustee
of the Fund owns 1% or more of its  outstanding  shares,  and the  officers  and
Trustees of each Fund own, as a group, less than 1% of the shares.
    
Other Matters to Come Before the Meeting

         MMS's  management  does not know of any matters to be  presented at the
meeting other than those described in this Proxy Statement/Prospectus.  If other
business should  properly come before the meeting,  the  proxyholders  will vote
thereon in accordance with their best judgment.

Principal Underwriter

         PIMCO Funds  Distributors  LLC, whose address is 2187 Atlantic  Street,
Stamford, Connecticut 06902, is the principal underwriter for both the Municipal
Bond Fund and the Tax Exempt Fund.

Shareholder Proposals

         Proposals of  shareholders  must be received by MMS a  reasonable  time
prior to the  mailing  of proxy  materials  for a meeting of  shareholders.  The
submission  by a shareholder  of a proposal for  inclusion in a proxy  statement
does not guarantee that it will be included.  Shareholder  proposals are subject
to certain regulations under the federal securities laws.

                                   Appendix A

                  Form of Agreement and Plan of Reorganization

   
         This Agreement and Plan of Reorganization  (the "Agreement") is made as
of  April  7,  1998  by  and  between  PIMCO  Funds:   Multi-Manager  Series,  a
Massachusetts business trust (the "MMS Trust"), on behalf of its Tax Exempt Fund
(the  "Acquired  Fund"),  and PIMCO Funds, a  Massachusetts  business trust (the
"PIMS Trust"), on behalf of its Municipal Bond Fund (the "Acquiring Fund").
    
PLAN OF REORGANIZATION

         (a) The Acquired Fund will sell, assign,  convey,  transfer and deliver
to the Acquiring  Fund on the Exchange Date (as defined in Section 6) all of its
properties and assets. In consideration  therefor,  the Acquiring Fund shall, on
the Exchange Date,  assume all of the  liabilities of the Acquired Fund existing
at the Valuation  Time and deliver to the Acquired Fund (i) a number of full and
fractional  Class A shares of  beneficial  interest of the  Acquiring  Fund (the
"Class A Merger  Shares") having an aggregate net asset value equal to the value
of the  assets  of the  Acquired  Fund  attributable  to Class A  shares  of the
Acquired Fund  transferred  to the Acquiring Fund on such date less the value of
the  liabilities  of the  Acquired  Fund  attributable  to Class A shares of the
Acquired Fund assumed by the Acquiring Fund on that date,  (ii) a number of full
and fractional Class B shares of beneficial  interest of the Acquiring Fund (the
"Class B Merger  Shares") having an aggregate net asset value equal to the value
of the  assets  of the  Acquired  Fund  attributable  to Class B  shares  of the
Acquired Fund  transferred  to the Acquiring Fund on such date less the value of
the  liabilities  of the  Acquired  Fund  attributable  to Class B shares of the
Acquired Fund assumed by the Acquiring  Fund on that date, and (iii) a number of
full and fractional Class C shares of beneficial  interest of the Acquiring Fund
(the "Class C Merger  Shares")  having an aggregate net asset value equal to the
value of the assets of the Acquired Fund  attributable  to Class C shares of the
Acquired Fund  transferred  to the Acquiring Fund on such date less the value of
the  liabilities  of the  Acquired  Fund  attributable  to Class C shares of the
Acquired  Fund assumed by the Acquiring  Fund on that date.  (The Class A Merger
Shares,  the  Class B  Merger  Shares  and the  Class C Merger  Shares  shall be
referred to  collectively  as the  "Merger  Shares.")  It is  intended  that the
reorganization  described  in this Plan  shall be a  reorganization  within  the
meaning of Section 368 of the  Internal  Revenue  Code of 1986,  as amended (the
"Code").

         (b) Upon consummation of the transactions described in paragraph (a) of
this Plan of  Reorganization,  the Acquired  Fund shall  distribute  in complete
liquidation to its Class A, Class B and Class C shareholders of record as of the
Exchange Date Class A, Class B and Class C Merger Shares, each shareholder being
entitled to receive that  proportion of such Class A, Class B and Class C Merger
Shares  which  the  number of Class A,  Class B or Class C shares of  beneficial
interest of the Acquired  Fund held by such  shareholder  bears to the number of
Class A, Class B and Class C shares of the  Acquired  Fund  outstanding  on such
date. Certificates representing the Merger Shares will not be issued. All issued
and outstanding  shares of the Acquired Fund will  simultaneously be canceled on
the books of the Acquired Fund.
<PAGE>

         (c) As promptly as  practicable  after the  liquidation of the Acquired
Fund as  aforesaid,  the  Acquired  Fund  shall  be  dissolved  pursuant  to the
provisions  of the  Agreement  and  Declaration  of Trust of the MMS  Trust,  as
amended, and applicable law, and its legal existence  terminated.  Any reporting
responsibility  of the Acquired Fund is and shall remain the  responsibility  of
the Acquired Fund up to and including the Exchange Date and, if applicable, such
later date on which the Acquired Fund is liquidated.

AGREEMENT

         The Acquiring Fund and the Acquired Fund agree as follows:

         1.  Representations,  Warranties and Agreements of the Acquiring  Fund.
The Acquiring Fund  represents and warrants to and agrees with the Acquired Fund
that:

               a. The Acquiring  Fund is a series of shares of the PIMS Trust, a
          Massachusetts  business trust duly  established  and validly  existing
          under the laws of The Commonwealth of Massachusetts,  and has power to
          own all of its properties and assets and to carry out its  obligations
          under  this  Agreement.  The PIMS  Trust  is  qualified  as a  foreign
          association in every jurisdiction where required, except to the extent
          that failure to so qualify would not have a material adverse effect on
          the PIMS Trust.  Each of the PIMS Trust and the Acquiring Fund has all
          necessary  federal,  state  and local  authorizations  to carry on its
          business as now being conducted and to carry out this Agreement.

               b. The PIMS Trust is registered under the Investment  Company Act
          of 1940,  as  amended  (the "1940  Act"),  as an  open-end  management
          investment  company,  and such  registration  has not been  revoked or
          rescinded and is in full force and effect.

               c.  A  statement  of  assets  and   liabilities,   statements  of
          operations,  statements  of changes  in net  assets and a schedule  of
          investments  (indicating their market values) of the Acquiring Fund as
          of and for the period  ended March 31, 1998 will be  furnished  to the
          Acquired Fund prior to the Exchange Date. Such statement of assets and
          liabilities and schedule will fairly present the financial position of
          the Acquiring Fund as of their date and said  statements of operations
          and  changes in net assets  will  fairly  reflect  the  results of its
          operations and changes in net assets for the periods  covered  thereby
          in conformity with generally accepted accounting principles.
   
               d. The  prospectuses  and statement of additional  information of
          the PIMS  Trust,  each dated  April 1, 1998  (collectively,  the "PIMS
          Prospectus"), previously furnished to the Acquired Fund, did not as of
          such date and do not  contain,  with  respect to the PIMS Trust or the
          Acquiring  Fund,  any untrue  statements of a material fact or omit to
          state a material  fact  required to be stated  therein or necessary to
          make the statements therein not misleading.
    

<PAGE>

               e.  There  are  no  material  legal,   administrative   or  other
          proceedings  pending  or, to the  knowledge  of the PIMS  Trust or the
          Acquiring  Fund,  threatened  against the PIMS Trust or the  Acquiring
          Fund,  which  assert  liability  on the part of the PIMS  Trust or the
          Acquiring  Fund. The Acquiring Fund knows of no facts which might form
          the basis for the  institution of such  proceedings and is not a party
          to or subject to the  provisions  of any order,  decree or judgment of
          any court or governmental  body which materially and adversely affects
          its  business or its ability to  consummate  the  transactions  herein
          contemplated.

               f. The  Acquiring  Fund has no known  liabilities  of a  material
          nature,  contingent or otherwise,  other than those that will be shown
          as belonging to it on its  statement of assets and  liabilities  as of
          March 31, 1998 and those  incurred in the ordinary  course of business
          as an investment  company since such date. Prior to the Exchange Date,
          the  Acquiring  Fund will  endeavor to quantify  and to reflect on its
          balance sheet all of its material  known  liabilities  and will advise
          the  Acquired  Fund  of  all  material   liabilities,   contingent  or
          otherwise, incurred by it subsequent to March 31, 1998, whether or not
          incurred in the ordinary course of business.

               g. As of the Exchange  Date,  the Acquiring  Fund will have filed
          all federal and other tax returns and reports which,  to the knowledge
          of  the  PIMS  Trust's  officers,  are  required  to be  filed  by the
          Acquiring  Fund and has paid or will pay all  federal  and other taxes
          shown to be due on said returns or on any assessments  received by the
          Acquiring  Fund.  All tax  liabilities of the Acquiring Fund have been
          adequately  provided  for on its  books,  and  no  tax  deficiency  or
          liability of the  Acquiring  Fund has been  asserted,  and no question
          with  respect  thereto  has  been  raised  or is under  audit,  by the
          Internal  Revenue  Service or by any state or local tax  authority for
          taxes in excess of those already paid.

               h. No consent,  approval,  authorization or order of any court or
          governmental  authority  is  required  for  the  consummation  by  the
          Acquiring Fund of the  transactions  contemplated  by this  Agreement,
          except such as may be required  under the  Securities  Act of 1933, as
          amended  (the "1933 Act"),  the  Securities  Exchange Act of 1934,  as
          amended (the "1934 Act"),  the 1940 Act and state  securities  or blue
          sky laws  (which  term as used  herein  shall  include the laws of the
          District of Columbia and of Puerto Rico).

               i. The  registration  statement  (the  "Registration  Statement")
          filed with the Securities and Exchange  Commission (the  "Commission")
          by the PIMS  Trust on Form N-14 on behalf  of the  Acquiring  Fund and
          relating  to the  Merger  Shares  issuable  hereunder,  and the  proxy
          statement of the Acquired Fund relating to the meeting of the Acquired
          Fund's shareholders  referred to in Section 7(a) herein (together with
          the documents  incorporated  therein by reference,  the "Acquired Fund
          Proxy Statement"), on the effective date of the Registration Statement
          (i) complies in all material  respects with the provisions of the 1933
          Act,  the  1934 Act and the 1940  Act and the  rules  and  regulations
<PAGE>
 

         thereunder  and (ii)  does  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 not  misleading;
          and at the time of the  shareholders  meeting  referred  to in Section
          7(a) and on the Exchange Date,  the  prospectus  which is contained in
          the  Registration   Statement,  as  amended  or  supplemented  by  any
          amendments or supplements filed with the Commission by the PIMS Trust,
          and the  Acquired  Fund Proxy  Statement  will 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 not
          misleading;  provided,  however,  that none of the representations and
          warranties  in  this  subsection  shall  apply  to  statements  in  or
          omissions from the  Registration  Statement or the Acquired Fund Proxy
          Statement  made in reliance  upon and in conformity  with  information
          furnished by the Acquired Fund for use in the  Registration  Statement
          or the Acquired Fund Proxy Statement.

               j.  There  are no  material  contracts  outstanding  to which the
          Acquiring  Fund is a party,  other  than as will be  disclosed  in the
          Registration Statement, the PIMS Prospectus or the Acquired Fund Proxy
          Statement.

               k.  To  the  best  of  its  knowledge,  all  of  the  issued  and
          outstanding  shares of beneficial  interest of the Acquiring Fund have
          been  offered  for  sale and sold in  conformity  with all  applicable
          federal and state securities laws (including any applicable exemptions
          therefrom),  or the Acquiring  Fund has taken any action  necessary to
          remedy any prior failure to have offered for sale and sold such shares
          in conformity with such laws.

               l. The Acquiring Fund qualifies and will at all times through the
          Exchange Date qualify for taxation as a "regulated investment company"
          under Sections 851 and 852 of the Code.

               m. The issuance of the Merger Shares  pursuant to this  Agreement
          will be in compliance with all applicable federal and state securities
          laws.

               n. The Merger  Shares to be issued to the Acquired Fund have been
          duly  authorized  and,  when  issued and  delivered  pursuant  to this
          Agreement,  will be legally and validly  issued and will be fully paid
          and  nonassessable  by the Acquiring  Fund,  and no shareholder of the
          Acquiring  Fund  will have any  preemptive  right of  subscription  or
          purchase in respect thereof.

               o. All issued and  outstanding  shares of the Acquiring Fund are,
          and at the  Exchange  Date  will  be,  duly  and  validly  issued  and
          outstanding,  fully paid and non-assessable by the Acquiring Fund. The
          Acquiring  Fund does not have  outstanding  any  options,  warrants or
          other rights to subscribe  for or purchase any of the  Acquiring  Fund
          shares, nor is there outstanding any security  convertible into any of
          the Acquiring Fund shares.

         2. Representations, Warranties and Agreements of the Acquired Fund. The
Acquired  Fund  represents  and warrants to and agrees with the  Acquiring  Fund
that:
<PAGE>

               a. The  Acquired  Fund is a series of shares of the MMS Trust,  a
          Massachusetts  business trust duly  established  and validly  existing
          under the laws of The Commonwealth of Massachusetts,  and has power to
          own all of its properties and assets and to carry out this  Agreement.
          The  MMS  Trust  is  qualified  as  a  foreign  association  in  every
          jurisdiction  where required,  except to the extent that failure to so
          qualify  would not have a  material  adverse  effect on the MMS Trust.
          Each of the MMS Trust and the Acquired Fund has all necessary federal,
          state and local authorizations to own all of its properties and assets
          and to carry on its business as now being  conducted  and to carry out
          this Agreement.

               b. The MMS Trust is registered  under the 1940 Act as an open-end
          management  investment  company,  and such  registration  has not been
          revoked or rescinded and is in full force and effect.

               c.  A  statement  of  assets  and   liabilities,   statements  of
          operations,  statements  of changes  in net  assets and a schedule  of
          investments  (indicating  their market values) of the Acquired Fund as
          of and for the period  ended March 31, 1998 will be  furnished  to the
          Acquiring  Fund prior to the Exchange  Date.  Such statement of assets
          and  liabilities  and  schedule  will  fairly  present  the  financial
          position of the Acquired Fund as of their date and said  statements of
          operations  and changes in net assets will fairly  reflect the results
          of its  operations  and changes in net assets for the periods  covered
          thereby in conformity with generally accepted accounting principles.

               d. The  prospectuses  and statement of additional  information of
          the MMS Trust,  each dated  February 5, 1998  (collectively,  the "MMS
          Prospectus"),  previously  furnished to the  Acquiring  Fund,  did not
          contain as of such date and do not  contain,  with  respect to the MMS
          Trust and the Acquired Fund,  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 not misleading.

               e.  There  are  no  material  legal,   administrative   or  other
          proceedings  pending  or,  to the  knowledge  of the MMS  Trust or the
          Acquired Fund,  threatened against the MMS Trust or the Acquired Fund,
          which  assert  liability  on the part of the MMS Trust or the Acquired
          Fund.  The Acquired  Fund knows of no facts which might form the basis
          for the  institution  of  such  proceedings  and is not a party  to or
          subject to the  provisions  of any order,  decree or  judgment  of any
          court or governmental  body which materially and adversely affects its
          business  or  its  ability  to  consummate  the  transactions   herein
          contemplated.

               f.  There  are no  material  contracts  outstanding  to which the
          Acquired  Fund is a  party,  other  than as will be  disclosed  in the
          Registration Statement,  the MMS Prospectus or the Acquired Fund Proxy
          Statement.

               g.  The  Acquired  Fund has no known  liabilities  of a  material
          nature,  contingent or otherwise,  other than those that will be shown
          on the Acquired Fund's statement of assets and liabilities as of March
          31, 1998 referred to above and those  incurred in the ordinary  course
          of its business as an investment company since such date. Prior to the
          Exchange  Date,  the  Acquired  Fund will  endeavor to quantify and to
          reflect on its balance sheet all of its material known liabilities and
          will advise the Acquiring Fund of all material liabilities, contingent
          or otherwise,  incurred by it subsequent to March 31, 1998, whether or
          not incurred in the ordinary course of business.
<PAGE>

               h. As of the Exchange Date, the Acquired Fund will have filed all
          federal and other tax returns and reports  which,  to the knowledge of
          the MMS Trust's  officers,  are  required to be filed by the  Acquired
          Fund and has paid or will pay all  federal and other taxes shown to be
          due on said  returns or on any  assessments  received by the  Acquired
          Fund. All tax  liabilities  of the Acquired Fund have been  adequately
          provided for on its books,  and no tax  deficiency or liability of the
          Acquired Fund has been asserted,  and no question with respect thereto
          has been raised or is under audit, by the Internal  Revenue Service or
          by any  state or local  tax  authority  for  taxes in  excess of those
          already paid.

               i. At the Exchange Date, the MMS Trust, on behalf of the Acquired
          Fund,  will have full  right,  power and  authority  to sell,  assign,
          transfer and deliver the  Investments (as defined below) and any other
          assets and  liabilities  of the Acquired Fund to be transferred to the
          Acquiring  Fund  pursuant to this  Agreement.  At the  Exchange  Date,
          subject  only to the  delivery of the  Investments  and any such other
          assets  and  liabilities  as  contemplated  by  this  Agreement,   the
          Acquiring Fund will acquire the  Investments and any such other assets
          and  liabilities  subject  to  no  encumbrances,   liens  or  security
          interests  whatsoever and without any  restrictions  upon the transfer
          thereof. As used in this Agreement,  the term "Investments" shall mean
          the  Acquired  Fund's   investments  shown  on  the  schedule  of  its
          investments  as of March 31, 1998  referred to in Section 2(c) hereof,
          as  supplemented  with such  changes in the  portfolio as the Acquired
          Fund shall make,  and changes  resulting from stock  dividends,  stock
          split-ups,  mergers and similar corporate actions through the Exchange
          Date.

               j. No  registration  under the 1933 Act of any of the Investments
          would be required if they were, as of the time of such  transfer,  the
          subject of a public  distribution  by either of the Acquiring  Fund or
          the Acquired  Fund,  except as  previously  disclosed to the Acquiring
          Fund by the Acquired Fund.

               k. No consent,  approval,  authorization or order of any court or
          governmental  authority  is  required  for  the  consummation  by  the
          Acquired  Fund of the  transactions  contemplated  by this  Agreement,
          except such as may be required  under the 1933 Act, 1934 Act, the 1940
          Act or state securities or blue sky laws.

               l.  The  Registration  Statement  and  the  Acquired  Fund  Proxy
          Statement,  on the effective date of the Registration  Statement,  (i)
          complies in all material respects with the provisions of the 1933 Act,
          the 1934 Act and the 1940 Act and the rules and regulations thereunder
          and (ii) does 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 not  misleading;  and at the
          time of the  shareholders  meeting  referred to in Section 7(a) and on
          the  Exchange  Date,  the  Acquired  Fund  Proxy   Statement  and  the
          Registration  Statement  will 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 not  misleading;
          provided,  however, that none of the representations and warranties in
          this  subsection  shall apply to statements  in or omissions  from the
          Registration  Statement or the Acquired Fund Proxy  Statement  made in
          reliance  upon and in  conformity  with  information  furnished by the
          Acquiring Fund for use in the  Registration  Statement or the Acquired
          Fund Proxy Statement.


<PAGE>

               m. The Acquired Fund  qualifies and will at all times through the
          Exchange Date qualify for taxation as a "regulated investment company"
          under Sections 851 and 852 of the Code.

               n. At the Exchange Date, the Acquired Fund will have sold such of
          its assets,  if any, as are  necessary  to assure  that,  after giving
          effect to the  acquisition of the assets of the Acquired Fund pursuant
          to this  Agreement,  the  Acquiring  Fund will  remain a  "diversified
          company"  within the meaning of Section 5(b)(1) of the 1940 Act and in
          compliance  with such other mandatory  investment  restrictions as are
          set forth in the PIMS  Prospectus,  as amended  through  the  Exchange
          Date.

               o.  To  the  best  of  its  knowledge,  all  of  the  issued  and
          outstanding  shares of beneficial  interest of the Acquired Fund shall
          have been offered for sale and sold in conformity  with all applicable
          federal and state securities laws (including any applicable exemptions
          therefrom),  or the  Acquired  Fund has taken any action  necessary to
          remedy any prior failure to have offered for sale and sold such shares
          in conformity with such laws.

               p. All issued and  outstanding  shares of the Acquired  Fund are,
          and at the  Exchange  Date  will  be,  duly  and  validly  issued  and
          outstanding,  fully paid and  non-assessable by the Acquired Fund. The
          Acquired Fund does not have outstanding any options, warrants or other
          rights to subscribe  for or purchase any of the Acquired  Fund shares,
          nor is there  outstanding  any  security  convertible  into any of the
          Acquired Fund shares,  except that Class B shares of the Acquired Fund
          are convertible into Class A shares of the Acquired Fund in the manner
          and on the terms described in the MMS Prospectus.

         3.    Reorganization.

               a. Subject to the requisite  approval of the  shareholders of the
          Acquired Fund and to the other terms and conditions  contained  herein
          (including  the  Acquired  Fund's  obligation  to  distribute  to  its
          shareholders  all of its  investment  company  taxable  income and net
          capital gain as described in Section 8(m)  hereof),  the Acquired Fund
          agrees to sell, assign, convey,  transfer and deliver to the Acquiring
          Fund, and the Acquiring Fund agrees to acquire from the Acquired Fund,
          on the Exchange  Date all of the  Investments  and all of the cash and
          other  properties and assets of the Acquired Fund,  whether accrued or
          contingent  (including  cash  received by the  Acquired  Fund upon the
          liquidation of the Acquired Fund of any  investments  purchased by the
          Acquired  Fund after March 31, 1998 and  designated  by the  Acquiring
          Fund as being  unsuitable  for it to  acquire),  in exchange  for that
          number of shares of beneficial interest of the Acquiring Fund provided
          for in Section 4 and the  assumption by the  Acquiring  Fund of all of
          the  liabilities of the Acquired Fund,  whether accrued or contingent,
          existing  at  the  Valuation  Time  except  for  the  Acquired  Fund's
          liabilities,  if any,  arising in connection with this Agreement.  The
          Acquired Fund will, as soon as  practicable  after the Exchange  Date,
          distribute all of the Merger Shares received by it to the shareholders
          of the Acquired  Fund in exchange for their Class A, Class B and Class
          C shares of the Acquired Fund.
<PAGE>

               b.  The  Acquired  Fund  will  pay or  cause  to be  paid  to the
          Acquiring Fund any interest, cash or such dividends,  rights and other
          payments  received by it on or after the Exchange Date with respect to
          the Investments and other  properties and assets of the Acquired Fund,
          whether accrued or contingent, received by it on or after the Exchange
          Date.  Any such  distribution  shall be deemed  included in the assets
          transferred  to the Acquiring  Fund at the Exchange Date and shall not
          be separately  valued  unless the  securities in respect of which such
          distribution is made shall have gone "ex" such  distribution  prior to
          the Valuation Time, in which case any such distribution  which remains
          unpaid at the Exchange Date shall be included in the  determination of
          the value of the assets of the Acquired Fund acquired by the Acquiring
          Fund.

               c. The  Valuation  Time  shall be 4:00 p.m.  Eastern  time on the
          Exchange  Date or such earlier or later day as may be mutually  agreed
          upon in writing by the parties hereto (the "Valuation Time").

         4. Exchange Date;  Valuation  Time. On the Exchange Date, the Acquiring
Fund will deliver to the Acquired Fund (i) a number of full and fractional Class
A Merger  Shares  having an aggregate  net asset value equal to the value of the
assets of the Acquired Fund  attributable to Class A shares of the Acquired Fund
transferred to the Acquiring Fund on such date less the value of the liabilities
of the Acquired Fund attributable to Class A shares of the Acquired Fund assumed
by the Acquiring Fund on that date, (ii) a number of full and fractional Class B
Merger  Shares  having an  aggregate  net asset  value equal to the value of the
assets of the Acquired Fund  attributable to Class B shares of the Acquired Fund
transferred to the Acquiring Fund on such date less the value of the liabilities
of the Acquired Fund attributable to Class B shares of the Acquired Fund assumed
by the Acquiring  Fund on that date,  and (iii) a number of full and  fractional
Class C Merger  Shares having an aggregate net asset value equal to the value of
the assets of the Acquired Fund  attributable  to Class C shares of the Acquired
Fund  transferred  to the  Acquiring  Fund on such  date  less the  value of the
liabilities of the Acquired Fund  attributable to Class C shares of the Acquired
Fund  assumed by the  Acquiring  Fund on that date,  determined  as  hereinafter
provided in this Section 4.

               a. The net asset value of the Merger  Shares to be  delivered  to
          the Acquired Fund, the value of the assets  attributable  to the Class
          A, Class B and Class C shares of the Acquired  Fund,  and the value of
          the  liabilities  attributable  to the  Class A,  Class B and  Class C
          shares of the Acquired Fund to be assumed by the Acquiring Fund, shall
          in each case be determined as of the Valuation Time.
<PAGE>

               b. The net asset value of the Class A, Class B and Class C Merger
          Shares  shall  be  computed  in the  manner  set  forth  in  the  PIMS
          Prospectus.  The value of the assets and  liabilities  of the Class A,
          Class B and Class C shares of the Acquired Fund shall be determined by
          the Acquiring Fund, in cooperation with the Acquired Fund, pursuant to
          procedures  which the Acquiring Fund would use in determining the fair
          market value of the Acquiring Fund's assets and liabilities.

               c. No  adjustment  shall be made in the net asset value of either
          the  Acquired  Fund  or  the  Acquiring  Fund  to  take  into  account
          differences in realized and unrealized gains and losses.

               d. The  Acquiring  Fund  shall  issue  the  Merger  Shares to the
          Acquired  Fund in  three  certificates  registered  in the name of the
          Acquired  Fund,   one   representing   Class  A  Merger  Shares,   one
          representing Class B Merger Shares and one representing Class C Merger
          Shares.  The Acquired Fund shall  distribute the Class A Merger Shares
          to the Class A shareholders of the Acquired Fund by redelivering  such
          certificate to the Acquiring Fund's transfer agent, which will as soon
          as  practicable  set up open  accounts for each Class A Acquired  Fund
          shareholder in accordance with written  instructions  furnished by the
          Acquired Fund.  The Acquired Fund shall  distribute the Class B Merger
          Shares  to  the  Class  B   shareholders   of  the  Acquired  Fund  by
          redelivering  such certificate to the Acquiring Fund's transfer agent,
          which will as soon as practicable  set up open accounts for each Class
          B Acquired Fund  shareholder in accordance  with written  instructions
          furnished by the Acquired Fund. The Acquired Fund shall distribute the
          Class C Merger Shares to the Class C shareholders of the Acquired Fund
          by  redelivering  such  certificate to the Acquiring  Fund's  transfer
          agent, which will as soon as practicable set up open accounts for each
          Class  C  Acquired  Fund   shareholder  in  accordance   with  written
          instructions  furnished  by the  Acquired  Fund.  With  respect to any
          Acquired  Fund  shareholder  holding  share  certificates  as  of  the
          Exchange Date, such certificates will from and after the Exchange Date
          be deemed to be  certificates  for the  Merger  Shares  issued to each
          shareholder in respect of the Acquired Fund shares represented by such
          certificates;  certificates representing the Merger Shares will not be
          issued to Acquired Fund shareholders.

               e.  The  Acquiring  Fund  shall  assume  all  liabilities  of the
          Acquired Fund,  whether accrued or contingent,  in connection with the
          acquisition of assets and subsequent  dissolution of the Acquired Fund
          or  otherwise,  except for the Acquired  Fund's  liabilities,  if any,
          pursuant to this Agreement.

         5.       Expenses, Fees, etc.

                  a.  Except as  otherwise  provided  in this  Section  5, PIMCO
         Advisors L.P., by  countersigning  this Agreement,  agrees that it will
         bear any and all costs and expenses of the transaction  incurred by the
         Acquiring  Fund.  The Acquired Fund agrees to pay any and all costs and
         expenses  of the  transaction  incurred by the  Acquired  Fund but not,
         however,  in an amount  exceeding  $24,241.  PIMCO  Advisors  L.P.,  by
         countersigning  this  Agreement,  agrees  that it will bear any and all
         costs and expenses of the transaction  incurred by the Acquired Fund to
         the  extent  that  they  exceed  $24,241.  Notwithstanding  any  of the
         foregoing,  costs and  expenses  will in any event be paid by the party
         directly  incurring  them if and to the  extent  that  the  payment  by
         another  party  of  such  costs  and  expenses   would  result  in  the
         disqualification  of such  party as a  "regulated  investment  company"
         within the meaning of Section 851 of the Code.

                  b. In the event the transaction contemplated by this Agreement
         is not consummated  solely by reason of the Acquiring Fund's failure to
         satisfy  or  fulfill  any of  its  obligations  or  duties  under  this
         Agreement or its being either  unwilling or unable to go forward  other
         than by reason of the nonfulfillment or failure of any condition to the
         Acquiring Fund's obligations referred to in Section 7 or Section 8, the
         Acquiring Fund shall pay directly all of its costs and expenses and all
         reasonable costs and expenses  incurred by or on behalf of the Acquired
         Fund  in  connection   with  such   transaction,   including,   without
         limitation, legal, accounting and filing fees.

                  c. In the event the transaction contemplated by this Agreement
         is not  consummated  solely by reason of the Acquired Fund's failure to
         satisfy  or  fulfill  any of  its  obligations  or  duties  under  this
         Agreement or its being either  unwilling or unable to go forward  other
         than by reason of the nonfulfillment or failure of any condition to the
         Acquired Fund's obligations  referred to in Section 7 or Section 9, the
         Acquired  Fund shall pay directly all of its costs and expenses and all
         reasonable costs and expenses incurred by or on behalf of the Acquiring
         Fund  in  connection   with  such   transaction,   including,   without
         limitation, legal, accounting and filing fees.

                  d. In the event the transaction contemplated by this Agreement
         is not consummated for reasons specified in both paragraphs (b) and (c)
         of this  Section 5, then each of the  Acquiring  Fund and the  Acquired
         Fund  shall  bear  all  of its  own  costs  and  expenses  incurred  in
         connection with such transaction.

                  e. In the event the transaction contemplated by this Agreement
         is not consummated for reasons other than those specified in paragraphs
         (b) or (c) of this Section 5, then PIMCO  Advisors L.P.  shall bear all
         costs and expenses  incurred by the Acquiring  Fund in connection  with
         such  transaction and the Acquired Fund shall bear all of its own costs
         and expenses incurred in connection with such transaction.
<PAGE>

                  f. Notwithstanding any other provisions of this Agreement,  if
         for any reason the  transaction  contemplated  by this Agreement is not
         consummated,  no party  shall be  liable  to the  other  party  for any
         damages   resulting   therefrom,    including,    without   limitation,
         consequential damages, except as specifically set forth above.

transferred,  assumption of the  liabilities of the Acquired Fund to be assumed,
and the delivery of the Merger  Shares to be issued shall be made at the offices
of Dechert, Price & Rhoads, 1775 Eye Street, N.W., Washington, D.C. 20006, as of
the close of business on June 26, 1998, or at such other time and date agreed to

         7.  Meetings of Shareholders; Dissolution.

               a. The MMS Trust, on behalf of the Acquired Fund,  agrees to call

          practicable after the effective date of the Registration Statement for
          the  purpose of  considering  the sale of all of its assets to and the
          assumption of all of its  liabilities  by the Acquiring Fund as herein
          provided, adopting this Agreement, and authorizing the liquidation and
          dissolution of the Acquired Fund.

               b. The Acquired Fund agrees that the  liquidation and dissolution
          of the  Acquired  Fund will be effected in the manner  provided in the
          MMS Trust's  Agreement and  Declaration  of Trust in  accordance  with
          applicable  law and that on and after the Exchange  Date, the Acquired
          Fund shall not  conduct any  business  except in  connection  with its
          liquidation and dissolution.

               c. The Acquiring Fund has, after the  preparation and delivery to
          the Acquired  Fund by the Acquiring  Fund of a preliminary  version of
          the Registration Statement and the Acquired Fund Proxy Statement which
          were  satisfactory to the Acquired Fund and to Ropes & Gray, filed the
          Registration Statement with the Commission.  Each of the Acquired Fund
          and the Acquiring Fund will  cooperate  with the other,  and each will
          furnish to the other the  information  relating to itself  required by
          the  1933  Act,  the  1934  Act and the  1940  Act and the  rules  and
          regulations  thereunder to be set forth in the Registration  Statement
          and the Acquired Fund Proxy Statement.

         8. Conditions to the Acquiring Fund's  Obligations.  The obligations of
the Acquiring Fund hereunder shall be subject to the following conditions:

               a.  That  this   Agreement   shall  have  been  adopted  and  the
          transactions  contemplated  hereby  shall  have been  approved  by the
          requisite votes of the holders of the outstanding shares of beneficial
          interest of the Acquired Fund entitled to vote.

               b. That the Acquired  Fund shall have  furnished to the Acquiring
          Fund a statement of the Acquired Fund's assets and  liabilities,  with
          values determined as provided in Section 4 of this Agreement, together
          with a list of Investments  with their respective tax costs, all as of
          the Valuation Time, certified on the Acquired Fund's behalf by the MMS
          Trust's  President  (or  any  Vice  President)  and  Treasurer,  and a
          certificate of both such officers, dated the Exchange Date, that there
          has been no material  adverse change in the financial  position of the
          Acquired  Fund  since  March  31,  1998  other  than  changes  in  the
          Investments and other assets and properties since that date or changes
          in the  market  value  of the  Investments  and  other  assets  of the
          Acquired  Fund,  or  changes  due to  dividends  paid or  losses  from
          operations.
<PAGE>

               c. That the Acquired  Fund shall have  furnished to the Acquiring
          Fund a statement,  dated the Exchange Date,  signed by the MMS Trust's
          President (or any Vice President) and Treasurer  certifying that as of
          the Exchange Date all  representations  and warranties of the Acquired
          Fund  made in this  Agreement  are true and  correct  in all  material
          respects as if made at and as of such date and the  Acquired  Fund has
          complied with all the  agreements  and satisfied all the conditions on
          its part to be performed or satisfied at or prior to such date.

          Fund a letter  from  Price  Waterhouse  LLP  dated the  Exchange  Date
          stating that such firm has employed certain  procedures whereby it has
          obtained  schedules of the tax  provisions  and  qualifying  tests for
          regulated  investment companies as prepared for the period ended March
          31, 1998 and the period April 1, 1998 to the Exchange Date (the latter
          period being based on unaudited  data) and that, in the course of such
          procedures,  nothing  came to their  attention  which  caused  them to
          believe  that the  Acquired  Fund (i) would not qualify as a regulated
          investment company for federal, state, or local income tax purposes or
          (ii) would owe any  federal,  state or local income tax or excise tax,
          for the tax year ended June 30, 1997,  and for the period from July 1,
          1997 to the Exchange Date.

          respect to the matters contemplated by this Agreement.

               f. That the  Acquiring  Fund  shall have  received  an opinion of
          Ropes & Gray, in form satisfactory to Dechert Price & Rhoads,  counsel
          to the Acquiring Fund, and dated the Exchange Date, to the effect that
          (i) the MMS Trust is a Massachusetts business trust duly formed and is
          validly  existing under the laws of The  Commonwealth of Massachusetts
          and  has the  power  to own all its  properties  and to  carry  on its
          business as presently  conducted;  (ii) this  Agreement  has been duly
          authorized,  executed and  delivered by the MMS Trust on behalf of the

          Act,  the 1934 Act and the 1940 Act and  assuming  due  authorization,
          execution  and delivery of this  Agreement by the PIMS Trust on behalf
          of the Acquiring  Fund,  is a valid and binding  obligation of the MMS
          Trust and the  Acquired  Fund;  (iii) the MMS Trust,  on behalf of the
          Acquired Fund, has power to sell, assign, convey, transfer and deliver
          the  assets   contemplated   hereby  and,  upon  consummation  of  the
          transactions  contemplated hereby in accordance with the terms of this
          Agreement, the Acquired Fund will have duly sold, assigned,  conveyed,
          transferred  and delivered such assets to the Acquiring Fund; (iv) the
          execution and delivery of this Agreement did not, and the consummation
          of the  transactions  contemplated  hereby  will not,  violate the MMS
          Trust's Agreement and Declaration of Trust or By-Laws or any provision
          of any  agreement  known to such counsel to which the MMS Trust or the
          Acquired Fund is a party or by which it is bound, it being  understood
          that with  respect to  investment  restrictions  contained  in the MMS
          Trust's  Agreement and  Declaration of Trust,  By-Laws or then-current
          prospectuses or statement of additional information,  such counsel may
          rely  upon  a  certificate  of an  officer  of  the  MMS  Trust  whose
          responsibility  it is to advise  the MMS Trust and the  Acquired  Fund
          with  respect  to  such  matters;   and  (v)  no  consent,   approval,
          authorization  or order  of any  court or  governmental  authority  is
          required  for the  consummation  by the MMS  Trust  on  behalf  of the
          Acquired Fund of the transactions  contemplated hereby, except such as

          representations and subject to certain qualifications),  to the effect
          that,  on the basis of the existing  provisions  of the Code,  current
          administrative  rules,  and court  decisions,  for federal  income tax
          purposes (i) no gain or loss will be recognized by the Acquiring  Fund

               j. That the  Registration  Statement shall have become  effective
          under the 1933 Act, and no stop order  suspending  such  effectiveness

          the Acquiring Fund, threatened by the Commission.

          upon by the  Acquiring  Fund and  described in such letter (but not an
          examination in accordance with generally accepted auditing standards),
          as of the Valuation  Time the value of the assets and  liabilities  of

          requisite votes of the holders of the outstanding shares of beneficial
          interest of the Acquired Fund entitled to vote.

          and Treasurer (or any Assistant Treasurer),  and a certificate of both
          such  officers,  dated the Exchange Date, to the effect that as of the
          Valuation  Time and as of the Exchange Date there has been no material
          adverse  change in the financial  position of the Acquiring Fund since
          March 31, 1998,  other than changes in its portfolio  securities since
          that date,  changes in the market value of the  portfolio  securities,

          pursuant to this Agreement.

               d. That the Acquiring  Fund shall have  furnished to the Acquired
          Fund a statement,  dated the Exchange Date, signed by the PIMS Trust's
          President  (or any Vice  President)  and  Treasurer  (or any Assistant
          Treasurer) certifying that as of the Exchange Date all representations
          and  warranties of the Acquiring  Fund made in this Agreement are true
          and  correct  in all  material  respects  as if made at and as of such
          date,  and  that  the  Acquiring  Fund  has  complied  with all of the
          agreements  and  satisfied  all of the  conditions  on its  part to be
          performed or satisfied at or prior to such date.

               e. That there  shall not be any  material  litigation  pending or

          Dechert Price & Rhoads, in form satisfactory to Ropes & Gray,  counsel
          to the Acquired  Fund, and dated the Exchange Date, to the effect that
          (i) the PIMS Trust is a  Massachusetts  business trust duly formed and
          is  validly   existing   under  the  laws  of  The   Commonwealth   of
          Massachusetts and has the power to own all its properties and to carry
          on its business as presently  conducted;  (ii) the Merger Shares to be
          delivered to the Acquired  Fund as provided for by this  Agreement are
          duly authorized and upon such delivery will be validly issued and will
          be fully paid and  nonassessable  by the PIMS Trust and the  Acquiring
          Fund and no shareholder of the Acquiring Fund has any preemptive right
          to subscription or purchase in respect  thereof;  (iii) this Agreement
          has been duly authorized,  executed and delivered by the PIMS Trust on
          behalf of the Acquiring  Fund and,  assuming that the MMS  Prospectus,
          the  Registration  Statement  and the  Acquired  Fund Proxy  Statement
          comply with the 1933 Act,  the 1934 Act and the 1940 Act and  assuming
          due authorization, execution and delivery of this Agreement by the MMS
          Trust  on  behalf  of  the  Acquired  Fund,  is a  valid  and  binding
          obligation  of the  PIMS  Trust  and  the  Acquiring  Fund;  (iv)  the
          execution and delivery of this Agreement did not, and the consummation
          of the  transactions  contemplated  hereby will not,  violate the PIMS
          Trust's  Declaration  of Trust or  By-Laws,  or any  provision  of any
          agreement  known  to such  counsel  to  which  the  PIMS  Trust or the
          Acquiring Fund is a party or by which it is bound, it being understood
          that with respect to investment  restrictions as contained in the PIMS
          Trust's Declaration of Trust, By-Laws or then-current  prospectuses or
          statement  of  additional  information,  such  counsel may rely upon a
          certificate of an officer of the PIMS Trust whose responsibility it is
          to advise the PIMS Trust and the  Acquiring  Fund with respect to such
          matters; (v) no consent, approval, authorization or order of any court
          or governmental authority is required for the consummation by the PIMS
          Trust on behalf of the Acquiring Fund of the transactions contemplated
          herein, except such as have been obtained under the 1933 Act, the 1934
          Act  and  the  1940  Act  and  such  as may be  required  under  state
          securities or blue sky laws; and (vi) the  Registration  Statement has
          become  effective  under the 1933 Act, and to best of the knowledge of
          such  counsel,  no stop  order  suspending  the  effectiveness  of the
          Registration  Statement  has been issued and no  proceedings  for that
          purpose have been instituted or are pending or contemplated  under the
          1933 Act.

               g. That the Acquired Fund shall have received an opinion of Ropes
          & Gray,  dated the Exchange  Date (which  opinion  would be based upon
          certain    factual    representations    and    subject   to   certain
          qualifications),  in form  satisfactory  to the  Acquired  Fund to the
          effect  that,  on the basis of the  existing  provisions  of the Code,
          current administrative rules, and court decisions,  for federal income
          tax  purposes:  (i) no gain or loss will be recognized by the Acquired
          Fund as a result of the  reorganization;  (ii) no gain or loss will be
          recognized by shareholders of the Acquired Fund on the distribution of
          Merger  Shares to them in exchange  for their  shares of the  Acquired
          Fund;  (iii)  the tax basis of the  Merger  Shares  that the  Acquired
          Fund's  shareholders  receive in place of their  Acquired  Fund shares
          will be the same as the basis of the Acquired Fund shares;  and (iv) a
          shareholder's  holding period for the Merger Shares received  pursuant
          to the Agreement  will be  determined by including the holding  period
          for the Acquired Fund shares exchanged for the Merger Shares, provided
          that the shareholder held the Acquired Fund shares as a capital asset.

               h.  That all  actions  taken by the PIMS  Trust on  behalf of the
          Acquiring Fund in connection  with the  transactions  contemplated  by
          this  Agreement  and  all  documents   incidental   thereto  shall  be
          satisfactory  in form and  substance to the Acquired  Fund and Ropes &
          Gray.

               i. That the  Registration  Statement shall have become  effective
          under the 1933 Act, and no stop order  suspending  such  effectiveness
          shall have been  instituted  or, to the knowledge of the PIMS Trust or
          the Acquiring Fund, threatened by the Commission.

                  j. That the MMS Trust and PIMS Trust shall have  received from

         blue sky laws in connection with the transactions  contemplated hereby,
         and that all such orders shall be in full force and effect.

                  10.      Indemnification.

                  a. The Acquired Fund shall indemnify and hold harmless, out of
         the assets of the  Acquired  Fund (which shall be deemed to include the
         assets of the Acquiring Fund represented by the Merger Shares following
         the Exchange  Date) but no other  assets,  the trustees and officers of
         the PIMS Trust (for  purposes of this  subparagraph,  the  "Indemnified
         Parties")  against any and all expenses,  losses,  claims,  damages and
         liabilities at any time imposed upon or reasonably  incurred by any one
         or more of the Indemnified  Parties in connection with, arising out of,
         or resulting  from any claim,  action,  suit or proceeding in which any
         one or more of the  Indemnified  Parties  may be involved or with which
         any one or more of the Indemnified  Parties may be threatened by reason
         of any untrue  statement or alleged untrue statement of a material fact
         relating  to the  MMS  Trust  or the  Acquired  Fund  contained  in the
         Registration  Statement,  the MMS Prospectus or the Acquired Fund Proxy
         Statement or any amendment or supplement  to any of the  foregoing,  or
         arising out of or based upon the omission or alleged  omission to state
         in any of the  foregoing a material  fact  relating to the MMS Trust or
         the Acquired  Fund  required to be stated  therein or necessary to make
         the  statements  relating to the MMS Trust or the Acquired Fund therein
         not misleading,  including, without limitation, any amounts paid by any
         one or more of the  Indemnified  Parties in a reasonable  compromise or
         settlement of any such claim, action, suit or proceeding, or threatened
         claim,  action,  suit or  proceeding  made with the  consent of the MMS
         Trust or the Acquired Fund. The Indemnified Parties will notify the MMS
         Trust  and the  Acquired  Fund in  writing  within  ten days  after the
         receipt by any one or more of the Indemnified  Parties of any notice of
         legal  process or any suit  brought  against or claim made against such
         Indemnified  Party as to any matters covered by this Section 10(a). The
         Acquired  Fund shall be entitled to  participate  at its own expense in
         the defense of any claim,  action,  suit or proceeding  covered by this
         Section 10(a), or, if it so elects, to assume at its expense by counsel
         satisfactory to the Indemnified  Parties the defense of any such claim,
         action,  suit or proceeding,  and if the Acquired Fund elects to assume
         such defense,  the Indemnified Parties shall be entitled to participate
         in the defense of any such claim,  action,  suit or proceeding at their
         expense.   The  Acquired  Fund's  obligation  under  Section  10(a)  to
         indemnify and hold harmless the Indemnified  Parties shall constitute a
         guarantee  of payment so that the  Acquired  Fund will pay in the first
         instance any expenses, losses, claims, damages and liabilities required
         to be paid by it under this Section  10(a) without the necessity of the
         Indemnified Parties' first paying the same.
<PAGE>

                  b. The Acquiring Fund shall  indemnify and hold harmless,  out
         of the assets of the Acquiring  Fund but no other assets,  the trustees
         and officers of the MMS Trust (for purposes of this  subparagraph,  the
         "Indemnified  Parties") against any and all expenses,  losses,  claims,
         damages and liabilities at any time imposed upon or reasonably incurred
         by any one or more  of the  Indemnified  Parties  in  connection  with,
         arising out of, or resulting from any claim, action, suit or proceeding
         in which any one or more of the Indemnified  Parties may be involved or
         with which any one or more of the Indemnified Parties may be threatened
         by reason of any untrue  statement  or alleged  untrue  statement  of a
         material  fact  relating  to  the  Acquiring   Fund  contained  in  the
         Registration Statement,  the PIMS Prospectus or the Acquired Fund Proxy
         Statement,  or any amendment or  supplement to any thereof,  or arising
         out of, or based upon, the omission or alleged omission to state in any
         of the  foregoing  a material  fact  relating  to the PIMS Trust or the
         Acquiring  Fund required to be stated  therein or necessary to make the
         statements relating to the PIMS Trust or the Acquiring Fund therein not
         misleading,  including, without limitation, any amounts paid by any one
         or  more of the  Indemnified  Parties  in a  reasonable  compromise  or
         settlement of any such claim, action, suit or proceeding, or threatened
         claim,  action,  suit or  proceeding  made with the consent of the PIMS
         Trust or the Acquiring  Fund. The  Indemnified  Parties will notify the
         MMS Trust and the Acquiring  Fund in writing  within ten days after the
         receipt by any one or more of the Indemnified  parties of any notice of
         legal  process or any suit  brought  against or claim made against such
         Indemnified  Party as to any matters covered by this Section 10(b). The
         Acquiring  Fund shall be entitled to  participate at its own expense in
         the defense of any claim,  action,  suit or proceeding  covered by this
         Section 10(b), or, if it so elects, to assume at its expense by counsel
         satisfactory to the Indemnified  Parties the defense of any such claim,
         action, suit or proceeding, and, if the Acquiring Fund elects to assume
         such defense,  the Indemnified Parties shall be entitled to participate
         in the defense of any such claim,  action,  suit or proceeding at their
         own expense.  The Acquiring Fund's  obligation under this Section 10(b)
         to indemnify and hold harmless the Indemnified Parties shall constitute
         a guarantee of payment so that the Acquiring Fund will pay in the first
         instance any expenses, losses, claims, damages and liabilities required
         to be paid by it under this Section  10(b) without the necessity of the
         Indemnified Parties' first paying the same.

         11. No Broker,  etc. Each of the Acquired  Fund and the Acquiring  Fund
represents  that  there is no person who has dealt with it, the MMS Trust or the
PIMS Trust,  who by reason of such  dealings,  is  entitled  to any  broker's or
finder's or other  similar  fee or  commission  arising out of the  transactions
contemplated by this Agreement.
<PAGE>

         12.  Termination.  The  Acquired  Fund and the  Acquiring  Fund may, by
mutual consent of the trustees on behalf of each Fund, terminate this Agreement,
and the Acquired Fund or the Acquiring Fund, after consultation with counsel and
by consent of their  trustees or an officer  authorized  by such  trustees,  may
waive  any  condition  to  their  respective  obligations   hereunder.   If  the
transactions   contemplated  by  this  Agreement  have  not  been  substantially
completed by December 31, 1998, this Agreement shall automatically  terminate on
that  date  unless  a later  date is  agreed  to by the  Acquired  Fund  and the
Acquiring Fund.

         13. Rule 145.  Pursuant to Rule 145 under the 1933 Act,  the  Acquiring
Fund will,  in  connection  with the issuance of any Merger Shares to any person
who at the  time of the  transaction  contemplated  hereby  is  deemed  to be an
affiliate of a party to the  transaction  pursuant to Rule  145(c),  cause to be
affixed  upon the  certificates  issued  to such  person  (if  any) a legend  as
follows:

         "THESE SHARES MAY NOT BE SOLD OR OTHERWISE  TRANSFERRED EXCEPT TO PIMCO
         MUNICIPAL  BOND  FUND  OR  ITS  PRINCIPAL   UNDERWRITER  UNLESS  (i)  A
         REGISTRATION  STATEMENT  WITH RESPECT  THERETO IS  EFFECTIVE  UNDER THE
         SECURITIES  ACT OF 1933, AS AMENDED,  OR (ii) IN THE OPINION OF COUNSEL
         REASONABLY SATISFACTORY TO THE FUND SUCH REGISTRATION IS NOT REQUIRED."

and,  further,  the Acquiring Fund will issue stop transfer  instructions to the
Acquiring  Fund's transfer agent with respect to such shares.  The Acquired Fund
will  provide  the  Acquiring  Fund on the  Exchange  Date  with the name of any
Acquired  Fund  shareholder  who is to the  knowledge  of the  Acquired  Fund an
affiliate of the Acquired Fund on such date.

         14.  Covenants,  etc.  Deemed  Material.  All  covenants,   agreements,

              Additional Information About the Municipal Bond Fund

         PIMCO  Funds:  Pacific  Investment  Management  Series  ("PIMS"  or the
"Trust") is an open-end management  investment company consisting of twenty-five
separate  investment  portfolios  (the  "Funds"),  one of  which  is  the  PIMCO
Municipal Bond Fund ("Municipal  Bond Fund").  Each Fund offers its shares in up
to six classes:  Class A, Class B, Class C, Class D, the Institutional Class and
the Administrative Class.

         This Proxy Statement/Prospectus  describes only those classes of shares
to be received  by  shareholders  of the Tax Exempt Fund in the  Reorganization,
i.e. Class A, Class B and Class C. Information  regarding the remaining  classes
are  contained  in  separate  prospectuses  and  in  the  Trust's  Statement  of
Additional  Information,  which are available  upon request to the Trust without
charge.

INVESTMENT RISKS AND CONSIDERATIONS

         The  following  are some of the  principal  risks of  investing  in the
Municipal  Bond Fund.  Investors  should  read this  Proxy  Statement/Prospectus
carefully for a more complete  discussion of the risks relating to an investment
in the Municipal  Bond Fund. The net asset value per share of the Municipal Bond
Fund  may be  less  at the  time  of  redemption  than  it  was at the  time  of
investment.  Generally,  the value of fixed income securities can be expected to
vary  inversely  with changes in prevailing  interest  rates,  i.e., as interest
rates rise,  market value tends to decrease,  and vice versa,  although this may
not be true in the case of inflation-indexed  bonds. In addition,  the Municipal
Bond Fund may invest in  securities  rated lower than Baa by Moody's or S&P (or,
if not rated,  determined by Pacific  Investment  Management to be of comparable
quality).  Such securities carry a high degree of credit risk and are considered
speculative by the major rating agencies.

         The Municipal Bond Fund's  investment  techniques may involve a form of
borrowing,  which may tend to  exaggerate  the effect on net asset  value of any
increase or decrease in the market value of the Municipal Bond Fund's  portfolio
and may require  liquidation of portfolio  positions when it is not advantageous
to do so. The Municipal Bond Fund may sell securities  short,  which exposes the
Municipal  Bond Fund to a risk of loss if the value of the  security  sold short
should increase.

         The Municipal Bond Fund may use derivative  instruments,  consisting of
futures,  options,  and options on futures,  for hedging  purposes or as part of
their investment strategies.  Use of these instruments may involve certain costs
and risks, including the risk that the Municipal Bond Fund could not close out a
position when it would be most  advantageous  to do so, the risk of an imperfect
correlation  between the value of the  securities  being hedged and the value of
the particular  derivative  instrument,  and the risk that unexpected changes in
interest  rates may  adversely  affect the value of the  Municipal  Bond  Fund's
investments in particular  derivative  instruments.  Unless otherwise indicated,
all limitations  applicable to the Municipal Bond Fund investments (as stated in
this Proxy Statement/Prospectus,  the Trust's Class A, B and C Prospectus and in
<PAGE>


the  Trust's  Statement  of  Additional  Information)  apply  only at the time a
transaction is entered into. Any subsequent  change in a rating  assigned by any
rating  service  to a  security  (or,  if  unrated,  deemed to be of  comparable
quality),  or change in the percentage of Municipal Bond Fund assets invested in
certain  securities or other  instruments,  or change in the average duration of
the  Municipal  Bond  Fund's   investment   portfolio,   resulting  from  market
fluctuations  or other changes in the Municipal  Bond Fund's total assets,  will
not require the Municipal  Bond Fund to dispose of an  investment  until Pacific
Investment  Management  determines  that is practicable to sell or close out the
investment  without undue market or tax consequences to the Municipal Bond Fund.
In the  event  that  ratings  services  assign  different  ratings  to the  same
security,  Pacific Investment Management will determine which rating it believes
best  reflects the  security's  quality and risk at that time,  which may be the
higher of the several assigned ratings.

         The  Municipal   Bond  Fund  offers  its  shares  to  both  retail  and
institutional investors.  Institutional  shareholders,  some of whom also may be
investment  advisory clients of Pacific  Investment  Management,  may hold large
positions in the Municipal  Bond Fund.  Such  shareholders  may on occasion make
large  redemptions  of their  holdings in the Municipal  Bond Fund to meet their
liquidity  needs,  in connection  with  strategic  adjustments  to their overall
portfolio  of  investments,  or for other  purposes.  Large  redemptions  of the
Municipal  Bond Fund could require  Pacific  Investment  Management to liquidate
portfolio  positions  when it is not most  desirable  to do so.  Liquidation  of
portfolio  holdings  also may cause the Municipal  Bond Fund to realize  taxable
capital gains.

CHARACTERISTICS AND RISKS OF
SECURITIES AND INVESTMENT TECHNIQUES

         The following describes in greater detail different types of securities
and investment techniques used by the Municipal Bond Fund, and discusses certain
concepts relevant to the investment policies of the Fund. Additional information
about the Fund's  investments  and  investment  practices may be found in PIMS's
Statement of Additional Information.

         Municipal  Bonds.  The Municipal  Bond Fund invests in Municipal  Bonds
which are generally  issued by states and local  governments and their agencies,
authorities and other instrumentalities.  The Municipal Bonds which the Fund may
purchase  include  general  obligation  bonds and limited  obligation  bonds (or
revenue bonds), including industrial development bonds issued pursuant to former
federal tax law. General  obligation bonds are obligations  involving the credit
of an issuer  possessing taxing power and are payable from that issuer's general
revenues  and not from any  particular  source.  Limited  obligation  bonds  are
payable  only from the revenues  derived from a particular  facility or class of
facilities  or, in some cases,  from the  proceeds of a special  excise or other
specific  revenue  source.  Tax-exempt  "private  activity" bonds and industrial
development bonds generally are also revenue bonds and thus are not payable from
the issuer's general revenues.

         Municipal  Bonds are  subject to credit and market  risk.  Credit  risk
relates to the ability of the issuer to make payments of principal and interest.
The ability of an issuer to make such payments  could be affected by litigation,
legislation or other  political  events or the bankruptcy of the issuer.  Market
risk relates to changes in a security's value as a result of changes in interest
rates.  Lower rated  Municipal  Bonds  generally  provide  higher yields but are
subject to greater credit and market risk than higher quality Municipal Bonds.


<PAGE>

         The secondary market for Municipal Bonds typically has been less liquid
than that for  taxable  debt/fixed  income  securities,  and this may affect the
Fund's ability to sell particular Municipal Bonds at then-current market prices,
especially  in periods  when other  investors  are  attempting  to sell the same
securities.

         The Municipal Bond Fund may invest in municipal  lease  obligations.  A
lease is not a full  faith and  credit  obligation  of the issuer and is usually
backed  only by the  borrowing  government's  unsecured  pledge  to make  annual
appropriations for lease payments. There have been challenges to the legality of
lease  financing  in  numerous   states,   and,  from  time  to  time,   certain
municipalities have considered not appropriating money for lease payments. These
securities may be less readily  marketable than other municipals.  The Municipal
Bond Fund may also purchase  unrated lease  obligations if determined by Pacific
Investment  Management to be of comparable  quality to rated securities in which
the Fund is permitted to invest.

         The  Municipal  Bond Fund may seek to  enhance  its yield  through  the
purchase  of  private  placements,  which  may  have  resale  restrictions.  The
Municipal  Bond Fund may not invest  more than 15% of its net assets in illiquid
securities,  including unmarketable private placements.  The Municipal Bond Fund
may invest in municipal  warrants.  Like options,  warrants may expire worthless
and they may have reduced  liquidity.  The  Municipal  Bond Fund will not invest
more than 5% of its net assets in municipal warrants.

         The  Municipal  Bond Fund may invest in  Municipal  Bonds  with  credit
enhancements  such as letters of credit,  municipal  bond  insurance and Standby
Bond Purchase Agreements ("SBPA").  Although defaults on insured Municipal Bonds
have been low to date and municipal  bond insurers have met their claims,  there
is no assurance this will continue.  An SBPA is a liquidity facility provided to
pay the purchase price of bonds that cannot be  re-marketed,  and does not cover
principal or interest under any other circumstances.

         The Municipal Bond Fund may invest in Residual  Interest  Bonds,  which
are created by dividing  the income  stream  provided by an  underlying  bond to
create  two  securities,  one short term and one long  term.  Rising  short-term
interest  rates result in lower  income for the  longer-term  portion,  and vice
versa.  The  longer-term  bonds can be very volatile and may be less liquid than
other Municipal Bonds of comparable  maturity.  The Municipal Bond Fund will not
invest more than 10% of its total assets in Residual Interest Bonds.

         The  Municipal  Bond Fund also may invest in  participation  interests.
Participation  interests are various  types of securities  created by converting
fixed  rate bonds  into  short-term,  variable  rate  certificates.  There is no
guarantee  the  interest  will be  exempt  because  the IRS  has  not  issued  a
definitive ruling on the matter.
<PAGE>

         Although  the  Municipal  Bond Fund  invests  principally  in Municipal
Bonds, it also may invest up to 20% of its net assets in other securities, whose
characteristics and risks are discussed below.

         U.S. Government  Securities U.S. Government  securities are obligations
of, or guaranteed by, the U.S.  Government,  its agencies or  instrumentalities.
The U.S. Government does not guarantee the net asset value of the Municipal Bond
Fund's shares.  Some U.S. Government  securities,  such as Treasury bills, notes
and  bonds,  and  securities  guaranteed  by the  Government  National  Mortgage
Association  ("GNMA"),  are supported by the full faith and credit of the United
States;  others,  such as those of the Federal Home Loan Banks, are supported by
the right of the issuer to borrow from the U.S. Treasury;  others, such as those
of the Federal  National  Mortgage  Association  ("FNMA"),  are supported by the
discretionary  authority  of  the  U.S.  Government  to  purchase  the  agency's
obligations;  and still  others,  such as those of the  Student  Loan  Marketing
Association,  are  supported  only by the  credit of the  instrumentality.  U.S.
Government  securities  include  securities  that have no coupons,  or have been
stripped of their unmatured interest coupons,  individual  interest coupons from
such  securities  that  trade  separately,  and  evidences  of  receipt  of such
securities.  Such securities may pay no cash income, and are purchased at a deep
discount  from  their  value  at  maturity.  Because  interest  on  zero  coupon
securities is not distributed on a current basis but is, in effect,  compounded,
zero  coupon  securities  tend  to  be  subject  to  greater  market  risk  than
interest-paying  securities of similar maturities.  Custodial receipts issued in
connection  with so-called  trademark zero coupon  securities,  such as CATs and
TIGRs,  are not  issued  by the  U.S.  Treasury,  and  are  therefore  not  U.S.
Government securities,  although the underlying bond represented by such receipt
is a debt obligation of the U.S. Treasury. Other zero coupon Treasury securities
(STRIPs and CUBEs) are direct obligations of the U.S. Government.

         Variable  And Floating  Rate  Securities  Variable  and  floating  rate
securities  provide for a periodic  adjustment  in the interest rate paid on the
obligations.  The terms of such obligations must provide that interest rates are
adjusted  periodically  based upon an interest rate adjustment index as provided
in the  respective  obligations.  The adjustment  intervals may be regular,  and
range  from  daily up to  annually,  or may be event  based,  such as based on a
change in the prime rate.

         The Municipal  Bond Fund may invest in floating  rate debt  instruments
("floaters"). The interest rate on a floater is a variable rate which is tied to
another  interest rate, such as a money-market  index or Treasury bill rate. The
interest  rate on a floater  resets  periodically,  typically  every six months.
While,  because  of the  interest  rate  reset  feature,  floaters  provide  the
Municipal  Bond Fund  with a  certain  degree  of  protection  against  rises in
interest  rates,  the Municipal  Bond Fund will  participate  in any declines in
interest rates as well.

         Inflation-Indexed   Bonds  Inflation-indexed  bonds  are  fixed  income
securities whose principal value is periodically  adjusted according to the rate
of inflation. The interest rate on these bonds is generally fixed at issuance at
a rate lower than typical  bonds.  Over the life of an  inflation-indexed  bond,
however,  interest will be paid based on a principal value which is adjusted for
inflation.


<PAGE>

         Inflation-indexed securities issued by the U.S. Treasury will initially
have maturities of five or ten years, although it is anticipated that securities
with other  maturities  will be issued in the future.  The  securities  will pay
interest  on  a  semi-annual   basis,   equal  to  a  fixed  percentage  of  the
inflation-adjusted  principal amount.  For example,  if an investor purchased an
inflation-indexed  bond with a par value of $1,000  and a 3% real rate of return
coupon  (payable 1.5%  semi-annually),  and inflation  over the first six months
were 1%,  the  mid-year  par  value of the bond  would be  $1,010  and the first
semi-annual  interest  payment would be $15.15 ($1,010 times 1.5%). If inflation
during the second half of the year reached 3%, the  end-of-year par value of the
bond would be $1,030 and the second semi-annual interest payment would be $15.45
($1,030 times 1.5%).

         If  the  periodic   adjustment  rate  measuring  inflation  falls,  the
principal  value of  inflation-indexed  bonds  will be  adjusted  downward,  and
consequently the interest  payable on these securities  (calculated with respect
to a smaller principal  amount) will be reduced.  Repayment of the original bond
principal upon maturity (as adjusted for inflation) is guaranteed in the case of
U.S.  Treasury  inflation-indexed  bonds,  even  during a period  of  deflation.
However,  the  current  market  value of the bonds is not  guaranteed,  and will
fluctuate.  The Municipal Bond Fund may also invest in other  inflation  related
bonds which may or may not provide a similar  guarantee.  If such a guarantee of
principal is not provided,  the adjusted  principal  value of the bond repaid at
maturity may be less than the original principal.

         The value of inflation-indexed  bonds is expected to change in response
to changes in real interest  rates.  Real interest rates in turn are tied to the
relationship   between  nominal  interest  rates  and  the  rate  of  inflation.
Therefore,  if  inflation  were to rise at a faster rate than  nominal  interest
rates,  real interest  rates might  decline,  leading to an increase in value of
inflation-indexed  bonds. In contrast,  if nominal interest rates increased at a
faster  rate than  inflation,  real  interest  rates  might  rise,  leading to a
decrease in value of inflation-indexed bonds.

         While these  securities  are  expected to be protected  from  long-term
inflationary trends,  short-term increases in inflation may lead to a decline in
value.  If interest rates rise due to reasons other than inflation (for example,
due to changes in currency  exchange  rates),  investors in these securities may
not be protected to the extent that the increase is not  reflected in the bond's
inflation measure.

         The U.S.  Treasury has only recently  begun  issuing  inflation-indexed
bonds. As such, there is no trading history of these  securities,  and there can
be no assurance that a liquid market in these instruments will develop, although
one is  expected.  Lack of a  liquid  market  may  impose  the  risk  of  higher
transaction costs and the possibility that the Municipal Bond Fund may be forced
to liquidate  positions when it would not be  advantageous  to do so. There also
can be no assurance that the U.S.  Treasury will issue any particular  amount of
inflation-indexed  bonds.  Certain  foreign  governments,  such  as  the  United
Kingdom,   Canada   and   Australia,   have  a   longer   history   of   issuing
inflation-indexed  bonds,  and there may be a more  liquid  market in certain of
these countries for these securities.

         The periodic adjustment of U.S.  inflation-indexed bonds is tied to the
Consumer Price Index for Urban Consumers ("CPI-U"),  which is calculated monthly
by the U.S. Bureau of Labor Statistics. The CPI-U is a measurement of changes in
the cost of living, made up of components such as housing, food,  transportation
and energy. Inflation-indexed bonds issued by a foreign government are generally
adjusted to reflect a comparable inflation index, calculated by that government.
There can be no  assurance  that the CPI-U or any foreign  inflation  index will
accurately  measure  the real  rate of  inflation  in the  prices  of goods  and
services.  Moreover,  there can be no assurance  that the rate of inflation in a
foreign  country  will be  correlated  to the rate of  inflation  in the  United
States.
<PAGE>

         Any increase in the principal amount of an inflation-indexed  bond will
be considered  taxable  ordinary  income,  even though  investors do not receive
their principal until maturity.  See "Taxes" for information  about the possible
tax consequences of investing in inflation-indexed bonds.

         High Yield Securities ("Junk Bonds") The Municipal Bond Fund may invest
up to 10% of its assets in securities  rated lower than Baa by Moody's or BBB by
S&P but rated at least Ba by Moody's or BB by S&P (or, if not rated,  determined
by Pacific Investment Management to be of comparable quality).  Securities rated
lower than Baa by Moody's or lower than BBB by S&P are sometimes  referred to as
"high yield" or "junk" bonds.  Securities rated Baa are considered by Moody's to
have some speculative  characteristics.  Investors should consider the following
risks  associated with high yield  securities  before investing in the Municipal
Bond Fund.

         Investing in high yield  securities  involves special risks in addition
to  the  risks   associated  with  investments  in  higher  rated  fixed  income
securities.  High yield securities may be regarded as predominately  speculative
with respect to the issuer's  continuing  ability to meet principal and interest
payments.  Analysis of the  creditworthiness of issuers of high yield securities
may be more complex than for issuers of higher quality debt securities,  and the
ability of the Municipal Bond Fund to achieve its  investment  objective may, to
the extent of its investments in high yield  securities,  be more dependent upon
such creditworthiness analysis than would be the case if the Municipal Bond Fund
were investing in higher quality securities.

         High yield  securities  may be more  susceptible  to real or  perceived
adverse  economic  and  competitive   industry   conditions  than  higher  grade
securities.  The  prices of high  yield  securities  have been  found to be less
sensitive to interest rate changes than more highly rated investments,  but more
sensitive to adverse economic downturns or individual corporate developments.  A
projection of an economic  downturn or of a period of rising interest rates, for
example,  could cause a decline in high yield security prices because the advent
of a recession  could lessen the ability of a highly  leveraged  company to make
principal and interest  payments on its debt  securities.  If the issuer of high
yield securities defaults, the Municipal Bond Fund may incur additional expenses
to seek recovery. In the case of high yield securities structured as zero coupon
or payment-in-kind securities, the market prices of such securities are affected
to a greater  extent by interest  rate changes,  and  therefore  tend to be more
volatile than securities which pay interest periodically and in cash.

         The secondary  markets on which high yield securities are traded may be
less liquid than the market for higher grade  securities.  Less liquidity in the
secondary trading markets could adversely affect and cause large fluctuations in
the daily net asset value of the Municipal Bond Fund's shares. Adverse publicity
and investor  perceptions,  whether or not based on  fundamental  analysis,  may
decrease the values and  liquidity  of high yield  securities,  especially  in a
thinly traded market.
<PAGE>

         The use of credit  ratings as the sole method of evaluating  high yield
securities can involve certain risks.  For example,  credit ratings evaluate the
safety of  principal  and interest  payments,  not the market value risk of high
yield securities. Also, credit rating agencies may fail to change credit ratings
in a timely fashion to reflect events since the security was last rated. Pacific
Investment  Management  does not rely solely on credit  ratings  when  selecting
securities  for the  Municipal  Bond  Fund,  and  develops  its own  independent
analysis of issuer credit quality.  If a credit rating agency changes the rating
of a portfolio security held by the Municipal Bond Fund, the Fund may retain the
portfolio  security  if  Pacific  Investment  Management  deems  it in the  best
interest of shareholders.

         Corporate Debt Securities  Corporate debt securities  include corporate
bonds, debentures, notes and other similar corporate debt instruments, including
convertible securities.  Debt securities may be acquired with warrants attached.
Corporate  income-producing  securities  may also include  forms of preferred or
preference  stock.  The rate of  interest on a corporate  debt  security  may be
fixed, floating or variable,  and may vary inversely with respect to a reference
rate. See "Variable and Floating Rate  Securities"  above. The rate of return or
return of  principal  on some debt  obligations  may be linked or indexed to the
level of exchange rates between the U.S.
dollar and a foreign currency or currencies.

         Investments  in  corporate  debt   securities   that  are  rated  below
investment  grade  (rated  below Baa  (Moody's)  or BBB (S&P)) are  described as
"speculative" both by Moody's and S&P. Such securities are sometimes referred to
as "junk  bonds,"  and may be  subject  to  greater  market  fluctuations,  less
liquidity and greater risk of loss of income or  principal,  including a greater
possibility of default or bankruptcy of the issuer of such securities,  than are
more highly rated debt securities.  Moody's also describes  securities rated Baa
as having speculative  characteristics.  Pacific Investment  Management seeks to
minimize  these risks  through  diversification,  in-depth  credit  analysis and
attention to current  developments in interest rates and market conditions.  See
"Description of Securities  Ratings."  Investments in high yield  securities are
discussed separately above under "High Yield Securities ("Junk Bonds")."

         Mortgage-Backed  and Other  Asset-Backed  Securities The Municipal Bond
Fund may invest in mortgage- or other asset-backed securities. The value of some
mortgage- or  asset-backed  securities in which the Municipal  Bond Fund invests
may be particularly sensitive to changes in prevailing interest rates, and, like
the other  investments  of the Municipal Bond Fund, the ability of the Municipal
Bond Fund to successfully  utilize these instruments may depend in part upon the
ability of Pacific  Investment  Management to forecast  interest rates and other
economic factors correctly.

         Mortgage-Pass-Through  Securities are securities representing interests
in "pools" of mortgage loans secured by residential or commercial  real property
in which payments of both interest and principal on the securities are generally
made  monthly,  in  effect  "passing  through"  monthly  payments  made  by  the
individual borrowers on the mortgage loans which underlie the securities (net of
fees paid to the issuer or  guarantor  of the  securities).  Early  repayment of
principal on some  mortgage-related  securities  (arising  from  prepayments  of
principal due to sale of the underlying property,  refinancing,  or foreclosure,
net of fees and costs which may be incurred) may expose the Municipal  Bond Fund
to a lower rate of return upon  reinvestment  of principal.  Also, if a security
subject to prepayment has been purchased at a premium,  the value of the premium
would be lost in the event of  prepayment.  Like other fixed income  securities,
when interest rates rise,  the value of a  mortgage-related  security  generally
will  decline;  however,  when  interest  rates  are  declining,  the  value  of
mortgage-related securities with prepayment features may not increase as much as
other fixed income securities.  The rate of prepayments on underlying  mortgages
will affect the price and  volatility of a  mortgage-related  security,  and may
have the  effect of  shortening  or  extending  the  effective  maturity  of the
security beyond what was anticipated at the time of purchase. To the extent that
unanticipated rates of prepayment on underlying mortgages increase the effective
maturity of a mortgage-related  security, the volatility of such security can be
expected to increase.
<PAGE>

         Payment  of  principal  and  interest  on  some  mortgage  pass-through
securities  (but not the  market  value  of the  securities  themselves)  may be
guaranteed by the full faith and credit of the U.S.  Government  (in the case of
securities  guaranteed by GNMA); or guaranteed by agencies or  instrumentalities
of the U.S.  Government  (in the case of  securities  guaranteed  by FNMA or the
Federal Home Loan Mortgage  Corporation  ("FHLMC"),  which are supported only by
the  discretionary  authority  of the U.S.  Government  to purchase the agency's
obligations).  Mortgage-related  securities created by non-governmental  issuers
(such as  commercial  banks,  savings and loan  institutions,  private  mortgage
insurance companies, mortgage bankers and other secondary market issuers) may be
supported  by various  forms of insurance or  guarantees,  including  individual
loan,  title,  pool and hazard  insurance  and  letters of credit,  which may be
issued by governmental entities, private insurers or the mortgage poolers.

         Collateralized     Mortgage    Obligations    ("CMOs")    are    hybrid
mortgage-related instruments. Interest and pre-paid principal on a CMO are paid,
in most cases, on a monthly basis.  CMOs may be collateralized by whole mortgage
loans  but  are  more  typically   collateralized   by  portfolios  of  mortgage
pass-through  securities guaranteed by GNMA, FHLMC, or FNMA. CMOs are structured
into  multiple  classes,  with each class bearing a different  stated  maturity.
Monthly  payments of principal,  including  prepayments,  are first  returned to
investors  holding the shortest  maturity  class;  investors  holding the longer
maturity classes receive  principal only after the first class has been retired.
CMOs  that are  issued or  guaranteed  by the U.S.  Government  or by any of its
agencies or instrumentalities  will be considered U.S. Government  securities by
the  Fund,  while  other  CMOs,  even  if  collateralized  by  U.S.   Government
securities,  will have the same status as other privately issued  securities for
purposes of applying the Fund's diversification tests.

         Commercial  Mortgage-Backed  Securities include securities that reflect
an interest in, and are secured by,  mortgage loans on commercial real property.
The market for commercial mortgage-backed securities developed more recently and
in terms of total  outstanding  principal  amount of issues is relatively  small
compared to the market for residential single-family mortgage-backed securities.
Many of the risks of investing in commercial  mortgage-backed securities reflect
the risks of  investing  in the real estate  securing  the  underlying  mortgage
loans. These risks reflect the effects of local and other economic conditions on
real  estate  markets,  the  ability of tenants to make loan  payments,  and the
ability of a property to attract and retain tenants.  Commercial mortgage-backed
securities may be less liquid and exhibit  greater price  volatility  than other
types of mortgage-related or asset-backed securities.

         Mortgage-Related   Securities   include  securities  other  than  those
described above that directly or indirectly represent a participation in, or are
secured by and payable from,  mortgage loans on real property,  such as mortgage
dollar  rolls  (see  "Reverse   Repurchase   Agreements,   Dollar   Rolls,   and
Borrowings"), CMO residuals or stripped mortgage-backed securities ("SMBS"), and
may be  structured  in classes  with rights to receive  varying  proportions  of
principal and interest.
<PAGE>

         A  common  type of SMBS  will  have  one  class  receiving  some of the
interest and most of the  principal  from the mortgage  assets,  while the other
class will receive most of the interest and the remainder of the  principal.  In
the  most  extreme  case,  one  class  will  receive  all of the  interest  (the
interest-only,  or "IO"  class),  while the other class will  receive all of the
principal (the  principal-only,  or "PO" class).  The yield to maturity on an IO
class is  extremely  sensitive  to the  rate of  principal  payments  (including
prepayments)  on the related  underlying  mortgage  assets,  and a rapid rate of
principal  payments may have a material  adverse  effect on the  Municipal  Bond
Fund's yield to maturity  from these  securities.  The  Municipal  Bond Fund has
adopted a policy under which the Fund will invest more than 5% of its net assets
in any combination of IO or PO securities. The Municipal Bond Fund may invest in
other  asset-backed  securities  that  have been  offered  to  investors.  For a
discussion of the characteristics of some of these instruments,  see the Trust's
Statement of Additional Information.

         Repurchase   Agreements  For  the  purpose  of  achieving  income,  the
Municipal  Bond Fund may enter  into  repurchase  agreements,  which  entail the
purchase of a  portfolio-eligible  security  from a bank or  broker-dealer  that
agrees to  repurchase  the  security  at the  Municipal  Bond  Fund's  cost plus
interest  within a specified  time  (normally one day). If the party agreeing to
repurchase should default, as a result of bankruptcy or otherwise, the Municipal
Bond Fund will seek to sell the  securities  which it holds,  which action could
involve  procedural  costs or delays in addition to a loss on the  securities if
their value should fall below their  repurchase  price.  The Municipal Bond Fund
will invest no more than 15% of its net assets  (taken at current  market value)
in repurchase agreements maturing in more than seven days.

         Reverse Repurchase  Agreements,  Dollar Rolls, And Borrowings A reverse
repurchase  agreement involves the sale of a security by the Municipal Bond Fund
and its agreement to repurchase  the  instrument at a specified  time and price.
Under a reverse  repurchase  agreement,  the  Municipal  Bond Fund  continues to
receive any principal and interest  payments on the underlying  security  during
the term of the  agreement.  The Municipal  Bond Fund  generally will maintain a
segregated  account  consisting  of assets  determined  to be liquid by  Pacific
Investment Management in accordance with procedures  established by the Board of
Trustees to cover its obligations  under reverse  repurchase  agreements and, to
this  extent,  a  reverse   repurchase   agreement  (or   economically   similar
transaction)  will not be  considered  a "senior  security"  subject to the 300%
asset coverage requirements  otherwise applicable to borrowings by the Municipal
Bond Fund.
<PAGE>

         The  Municipal  Bond Fund may enter  into  dollar  rolls,  in which the
Municipal Bond Fund sells  mortgage-backed  or other  securities for delivery in
the current month and simultaneously contracts to purchase substantially similar
securities  on a specified  future date.  In the case of dollar rolls  involving
mortgage-backed  securities,  the mortgage-backed  securities that are purchased
will be of the same type and will have the same interest rate as those sold, but
will be supported by  different  pools of  mortgages.  The  Municipal  Bond Fund
forgoes  principal  and interest  paid during the roll period on the  securities
sold in a  dollar  roll,  but the  Municipal  Bond  Fund is  compensated  by the
difference  between the  current  sales price and the lower price for the future
purchase as well as by any  interest  earned on the  proceeds of the  securities
sold. The Municipal  Bond Fund also could be compensated  through the receipt of
fee income  equivalent to a lower forward  price.  The Municipal  Bond Fund will
maintain a segregated  account  consisting of assets  determined to be liquid by
Pacific Investment  Management in accordance with procedures  established by the
Board of Trustees to cover its obligations under dollar rolls.

         To the extent that positions in reverse repurchase  agreements,  dollar
rolls or similar  transactions  are not  covered  through the  maintenance  of a
segregated  account  consisting of liquid assets at least equal to the amount of
any  forward  purchase  commitment,  such  transactions  would be subject to the
Municipal  Bond Fund's  limitations  on  borrowings,  which would  restrict  the
aggregate  of such  transactions  (plus any other  borrowings)  to 331/3% of the
Municipal Bond Fund's total assets. Apart from such transactions,  the Municipal
Bond Fund will not borrow money, except for temporary administrative purposes.

         Loans Of Portfolio  Securities For the purpose of achieving income, the
Municipal Bond Fund may lend its portfolio  securities to brokers,  dealers, and
other financial institutions, provided:

         (i)      the loan is secured  continuously by collateral  consisting of
                  U.S.   Government   securities,   cash  or  cash   equivalents
                  (negotiable  certificates of deposit,  bankers' acceptances or
                  letters of credit) maintained on a daily  mark-to-market basis
                  in an amount at least equal to the current market value of the
                  securities loaned;

         (ii)     the  Municipal  Bond Fund may at any time call the loan and 
                  obtain  the return of the  securities loaned;

         (iii)    the Municipal Bond Fund will receive any interest or dividends
                  paid on the loaned securities; and

         (iv)     the aggregate  market value of  securities  loaned will not at
                  any time exceed  331/3% of the total  assets of the  Municipal
                  Bond Fund.

         The Municipal Bond Fund's  performance will continue to reflect changes
in the value of the  securities  loaned  and will also  reflect  the  receipt of
either  interest,  through  investment of cash  collateral by the Municipal Bond
Fund in permissible investments,  or a fee, if the collateral is U.S. Government
securities.  Securities  lending  involves  the  risk of loss of  rights  in the
collateral  or delay in recovery of the  collateral  should the borrower fail to
return the security loaned or become insolvent.  The Municipal Bond Fund may pay
lending fees to the party arranging the loan.
<PAGE>
   
         When-Issued,  Delayed Delivery, and Forward Commitment Transactions The
Municipal Bond Fund may purchase or sell  securities on a  when-issued,  delayed
delivery,  or forward commitment basis. These transactions  involve a commitment
by the Municipal Bond Fund to purchase or sell  securities  for a  predetermined
price or yield,  with payment and delivery  taking place more than seven days in
the future,  or after a period longer than the customary  settlement  period for
that type of security.  When such purchases are outstanding,  the Municipal Bond
Fund will set aside and  maintain  until  the  settlement  date in a  segregated
account,  assets  determined  to be liquid by Pacific  Investment  Management in
accordance  with procedures  established by the Board of Trustees,  in an amount
sufficient  to  meet  the  purchase  price.  Typically,  no  income  accrues  on
securities  the Municipal  Bond Fund has committed to purchase prior to the time
delivery of the  securities is made,  although the Municipal  Bond Fund may earn
income on securities it has deposited in a segregated account. When purchasing a
security on a when-issued,  delayed delivery,  or forward  commitment basis, the
Municipal  Bond Fund assumes the rights and risks of ownership of the  security,
including the risk of price and yield fluctuations,  and takes such fluctuations
into account when  determining  its net asset value.  Because the Municipal Bond
Fund is not required to pay for the  security  until the  delivery  date,  these
risks are in addition to the risks  associated  with the  Municipal  Bond Fund's
other  investments.  If the  Municipal  Bond Fund  remains  substantially  fully
invested at a time when  when-issued,  delayed delivery,  or forward  commitment
purchases are outstanding,  the purchases may result in a form of leverage. When
the Municipal Bond Fund has sold a security on a when-issued,  delayed delivery,
or forward  commitment  basis,  the Municipal Bond Fund does not  participate in
future  gains or losses with  respect to the  security.  If the other party to a
transaction fails to deliver or pay for the securities,  the Municipal Bond Fund
could miss a favorable  price or yield  opportunity  or could suffer a loss. The
Municipal  Bond Fund may dispose of or  renegotiate  a  transaction  after it is
entered into, and may sell when-issued or forward  commitment  securities before
they are  delivered,  which may  result in a capital  gain or loss.  There is no
percentage  limitation  on the  extent  to which  the  Municipal  Bond  Fund may
purchase or sell  securities  on a  when-issued,  delayed  delivery,  or forward
commitment basis.
    
         Short Sales The Municipal  Bond Fund may from time to time effect short
sales as part of its overall portfolio management strategies,  including the use
of  derivative  instruments,  or to offset  potential  declines in value of long
positions in similar  securities as those sold short. A short sale (other than a
short sale against the box) is a transaction  in which the  Municipal  Bond Fund
sells a security  it does not own at the time of the sale in  anticipation  that
the market price of that security will decline. To the extent that the Municipal
Bond Fund  engages in short  sales,  it must  (except in the case of short sales
"against the box") maintain  asset coverage in the form of assets  determined to
be liquid  by  Pacific  Investment  Management  in  accordance  with  procedures
established  by the Board of  Trustees,  in a segregated  account,  or otherwise
cover its position in a permissible manner. A short sale is "against the box" to
the extent that the Municipal Bond Fund contemporaneously owns, or has the right
to obtain at no added cost, securities identical to those sold short.

         Derivative  Instruments  To the  extent  permitted  by  the  investment
objectives  and policies of the Municipal  Bond Fund,  the Fund may purchase and
write call and put  options,  enter into futures  contracts,  and use options on
futures  contracts as further  described  below. The Municipal Bond Fund may use
these techniques to hedge against changes in interest rates or securities prices
or as part of their overall investment strategies.  The Municipal Bond Fund will
maintain a segregated  account  consisting of assets  determined to be liquid by
Pacific Investment  Management in accordance with procedures  established by the
Board of Trustees (or, as permitted by applicable regulation, enter into certain
offsetting  positions)  to cover its  obligations  under  options and futures to
limit leveraging of the Fund.
<PAGE>

         Derivative  instruments are considered for these purposes to consist of
securities  or other  instruments  whose value is derived from or related to the
value of some other  instrument or asset,  and not to include  those  securities
whose  payment  of  principal  and/or  interest  depends  upon cash  flows  from
underlying assets,  such as  mortgage-related  or asset-backed  securities.  The
value of some  derivative  instruments  in which the Municipal Bond Fund invests
may be particularly sensitive to changes in prevailing interest rates, and, like
the other  investments  of the Municipal  Bond Fund,  the ability of the Fund to
successfully  utilize these  instruments  may depend in part upon the ability of
Pacific  Investment  Management to forecast  interest  rates and other  economic
factors correctly.  If Pacific Investment Management  incorrectly forecasts such
factors and has taken positions in derivative instruments contrary to prevailing
market trends, the Municipal Bond Fund could be exposed to the risk of loss.

         The  Municipal  Bond  Fund  might  not  employ  any of  the  strategies
described  below,  and no  assurance  can be given that any  strategy  used will
succeed. The use of these strategies involves certain special risks, including a
possible imperfect correlation, or even no correlation,  between price movements
of derivative instruments and price movements of related investments. While some
strategies  involving  derivative  instruments 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 related  investments  or  otherwise,  due to the
possible  inability of the  Municipal  Bond Fund to purchase or sell a portfolio
security at a time that  otherwise  would be favorable  or the possible  need to
sell a portfolio  security at a disadvantageous  time because the Municipal Bond
Fund is required to maintain  asset  coverage or offsetting  positions,  and the
possible  inability of the Municipal  Bond Fund to close out or to liquidate its
derivatives positions.

         Options on Securities and Securities  Indexes.  The Municipal Bond Fund
may purchase put and call options on U.S. Government securities, Municipal Bonds
and Municipal Bond indexes.  One purpose of purchasing put options is to protect
holdings in an underlying or related security  against a substantial  decline in
market  value.  One purpose of  purchasing  call  options is to protect  against
substantial  increases  in prices of  securities  the Fund  intends to  purchase
pending its ability to invest in such securities in an orderly manner. An option
on a security (or index) is a contract  that gives the holder of the option,  in
return for a  premium,  the right to buy from (in the case of a call) or sell to
(in the case of a put) the  writer of the  option the  security  underlying  the
option  (or the cash value of the index) at a  specified  exercise  price at any
time  during the term of the option.  The writer of an option on a security  has
the obligation  upon exercise of the option to deliver the  underlying  security
upon payment of the exercise price or to pay the exercise price upon delivery of
the underlying security.  Upon exercise,  the writer of an option on an index is
obligated  to pay the  difference  between  the cash  value of the index and the
exercise price multiplied by the specified  multiplier for the index option.  An
index is designed  to reflect  specified  facets of a  particular  financial  or
securities market, a specific group of financial  instruments or securities,  or
certain economic indicators.
<PAGE>

         The Municipal  Bond Fund may sell put or call options it has previously
purchased, which could result in a net gain or loss. The Municipal Bond Fund may
write a call or put option only if the option is "covered" by the Fund holding a
position in the  underlying  securities  or by other  means  which would  permit
immediate  satisfaction of the Fund's obligation as writer of the option.  Prior
to exercise or expiration, an option may be closed out by an offsetting purchase
or sale of an option of the same series.

         The  Municipal  Bond Fund may write covered  straddles  consisting of a
combination  of a call and a put  written  on the same  underlying  security.  A
straddle will be covered when sufficient assets are deposited to meet the Fund's
immediate obligations. The Municipal Bond Fund may use the same liquid assets to
cover both the call and put options where the exercise price of the call and put
are the same, or the exercise  price of the call is higher than that of the put.
In such  cases,  the  Municipal  Bond  Fund will also  segregate  liquid  assets
equivalent to the amount, if any, by which the put is "in the money."

         The purchase and writing of options involves certain risks.  During the
option  period,  the  covered  call writer has, in return for the premium on the
option,  given  up the  opportunity  to  profit  from a  price  increase  in the
underlying  security above the exercise price, but, as long as its obligation as
a writer  continues,  has  retained  the risk of loss  should  the  price of the
underlying  security  decline.  The writer of an option has no control  over the
time  when it may be  required  to  fulfill  its  obligation  as a writer of the
option.  Once an option writer has received an exercise notice, it cannot effect
a closing  purchase  transaction in order to terminate its obligation  under the
option and must deliver the underlying  security at the exercise price. If a put
or call option  purchased by the Fund is not sold when it has  remaining  value,
and if the market price of the underlying  security  remains equal to or greater
than the exercise price (in the case of a put), or remains less than or equal to
the  exercise  price  (in the case of a call),  the Fund  will  lose its  entire
investment  in the  option.  Also,  where a put or call  option on a  particular
security is purchased to hedge  against price  movements in a related  security,
the price of the put or call  option may move more or less than the price of the
related security. There can be no assurance that a liquid market will exist when
the  Fund  seeks  to close  out an  option  position.  Furthermore,  if  trading
restrictions or suspensions are imposed on the options markets,  the Fund may be
unable to close out a position.

         Over-the-counter  options in which the  Municipal  Bond Fund may invest
differ from traded options in that they are two-party contracts,  with price and
other terms  negotiated  between buyer and seller,  and generally do not have as
much market liquidity as exchange-traded options. The Municipal Bond Fund may be
required to treat as illiquid  over-the-counter options purchased and securities
being used to cover certain written over-the-counter options.

         Futures Contracts and Options on Futures Contracts.  The Municipal Bond
Fund may purchase and sell futures contracts on U.S.  Government  securities and
Municipal  Bonds,  as well as  purchase  put and call  options  on such  futures
contracts.
<PAGE>

         There are several risks  associated with the use of futures and futures
options for hedging  purposes.  There can be no  guarantee  that there will be a
correlation  between price movements in the hedging vehicle and in the portfolio
securities being hedged. An incorrect correlation could result in a loss on both
the hedged securities in the Municipal Bond Fund and the hedging vehicle so that
the  portfolio  return might have been  greater had hedging not been  attempted.
There can be no  assurance  that a liquid  market  will exist at a time when the
Municipal  Bond Fund seeks to close out a futures  contract or a futures  option
position.  Most  futures  exchanges  and  boards of trade  limit  the  amount of
fluctuation  permitted in futures  contract prices during a single day; once the
daily limit has been  reached on a  particular  contract,  no trades may be made
that day at a price beyond that limit. In addition, certain of these instruments
are relatively new and without a significant trading history. As a result, there
is no  assurance  that an active  secondary  market will  develop or continue to
exist.  Lack of a liquid  market for any reason may prevent the  Municipal  Bond
Fund from liquidating an unfavorable position, and the Municipal Bond Fund would
remain obligated to meet margin requirements until the position is closed.

         The  Municipal  Bond Fund may write covered  straddles  consisting of a
combination of a call and a put written on the same underlying futures contract.
A straddle  will be covered  when  sufficient  assets are  deposited to meet the
Municipal Bond Fund's immediate obligations. The Municipal Bond Fund may use the
same  liquid  assets to cover both the call and put options  where the  exercise
price of the call and put are the  same,  or the  exercise  price of the call is
higher than that of the put. In such cases,  the  Municipal  Bond Fund will also
segregate  liquid assets  equivalent to the amount,  if any, by which the put is
"in the money."

         The  Municipal  Bond Fund will only enter  into  futures  contracts  or
futures options which are  standardized and traded on a U.S. or foreign exchange
or board of trade,  or  similar  entity,  or quoted  on an  automated  quotation
system. The Municipal Bond Fund will use financial futures contracts and related
options  only for "bona  fide  hedging"  purposes,  as such term is  defined  in
applicable  regulations of the Commodities  Futures Trading Commission  ("CFTC")
or, with respect to positions in financial  futures and related  options that do
not qualify as "bona fide hedging" positions,  will enter such positions only to
the extent that aggregate  initial margin  deposits plus premiums paid by it for
open futures option  positions,  less the amount by which any such positions are
"in-the-money," would not exceed 5% of the Municipal Bond Fund's net assets.

         Hybrid Instruments A hybrid instrument can combine the  characteristics
of  securities,  futures,  and options.  For example,  the  principal  amount or
interest rate of a hybrid could be tied  (positively or negatively) to the price
of some commodity, currency or securities index or another interest rate (each a
"benchmark").  The interest  rate or (unlike most fixed income  securities)  the
principal  amount  payable at maturity of a hybrid  security may be increased or
decreased, depending on changes in the value of the benchmark.

         Hybrids  can be used as an  efficient  means of  pursuing  a variety of
investment goals, including currency hedging, duration management, and increased
total  return.  Hybrids may not bear interest or pay  dividends.  The value of a
hybrid or its interest  rate may be a multiple of a benchmark  and, as a result,
may be  leveraged  and move (up or  down)  more  steeply  and  rapidly  than the
benchmark.  These benchmarks may be sensitive to economic and political  events,
such as commodity shortages and currency  devaluations,  which cannot be readily
foreseen by the purchaser of a hybrid. Under certain conditions,  the redemption
value of a hybrid  could be zero.  Thus,  an  investment  in a hybrid may entail
significant  market risks that are not associated with a similar investment in a
traditional,  U.S. dollar-denominated bond that has a fixed principal amount and
pays a fixed rate or floating  rate of  interest.  The  purchase of hybrids also
exposes a Fund to the credit risk of the issuer of the hybrids.  These risks may
cause  significant  fluctuations  in the net asset value of the  Municipal  Bond
Fund.  Accordingly,  the Municipal  Bond Fund will invest no more than 5% of its
assets in hybrid instruments.
<PAGE>

         Certain issuers of structured  products such as hybrid  instruments may
be deemed to be  investment  companies  as defined in the 1940 Act. As a result,
the  Municipal  Bond Fund's  investments  in these  products  will be subject to
limits  applicable to investments in investment  companies and may be subject to
restrictions contained in the 1940 Act.

         Investment In Investment  Companies The Municipal  Bond Fund may invest
in  securities of other  investment  companies,  such as  closed-end  management
investment  companies,  or in pooled accounts or other investment vehicles. As a
shareholder of an investment  company,  the Fund may indirectly bear service and
other  fees  which  are in  addition  to the  fees the  Fund  pays  its  service
providers.

         Portfolio  Turnover The length of time the Municipal Bond Fund has held
a particular security is not generally a consideration in investment  decisions.
The investment  policies of the Municipal Bond Fund may lead to frequent changes
in the Fund's investments, particularly in periods of volatile market movements.
High  portfolio  turnover  (e.g.,  over 100%) involves  correspondingly  greater
expenses to the Municipal Bond Fund,  including  commissions or dealer  mark-ups
and other transaction costs on the sale of securities and reinvestments in other
securities.  See "Management of the  Trust--Portfolio  Transactions." Such sales
may result in realization of taxable capital gains. See "Taxes."

         Illiquid Securities The Municipal Bond Fund may invest up to 15% of its
net assets in  illiquid  securities.  Certain  illiquid  securities  may require
pricing at fair value as determined in good faith under the  supervision  of the
Board of Trustees.  Pacific Investment  Management may be subject to significant
delays in  disposing  of  illiquid  securities,  and  transactions  in  illiquid
securities may entail registration expenses and other transaction costs that are
higher than those for  transactions  in liquid  securities.  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 the Municipal Bond Fund has valued the securities. Illiquid securities are
considered to include,  among other things,  written  over-the-counter  options,
securities  or  other  liquid  assets  being  used as cover  for  such  options,
repurchase  agreements  with  maturities  in excess of seven days,  certain loan
participation interests, fixed time deposits which are not subject to prepayment
or provide for  withdrawal  penalties  upon  prepayment  (other  than  overnight
deposits),  securities that are subject to legal or contractual  restrictions on
resale and other securities which legally or in Pacific Investment  Management's
opinion may be deemed illiquid (not including securities issued pursuant to Rule
144A under the Securities Act of 1933 and certain  commercial paper that Pacific
Investment  Management has determined to be liquid under procedures  approved by
the Board of Trustees).

         Illiquid securities may include privately placed securities,  which are
sold  directly to a small  number of  investors,  usually  institutions.  Unlike
public  offerings,   such  securities  are  not  registered  under  the  federal
securities  laws.  Although certain of these securities may be readily sold, for
example,  under Rule 144A,  others may be  illiquid,  and their sale may involve
substantial delays and additional costs.
<PAGE>

         Service Systems-Year 2000 Problem. Many of the services provided to the
Municipal Bond Fund depend on the smooth  functioning of computer systems.  Many
systems in use today cannot distinguish between the year 1900 and the year 2000.
Should any of the service  systems fail to process  information  properly,  that
could have an adverse  impact on the Fund's  operation and services  provided to
shareholders.  Pacific  Investment  Management,  the  Distributor,   Shareholder
Servicing and Transfer Agent, Custodian,  and certain other service providers to
the Fund  have  reported  that  each is  working  toward  mitigating  the  risks
associated  with the so-called  "year 2000  problem."  However,  there can be no
assurance that the problem will be corrected in all respects and that the Fund's
operations and services provided to shareholders will not be adversely affected.

HOW TO BUY SHARES

         Class A,  Class B and  Class C shares  of the  Municipal  Bond Fund are
continuously  offered  through the Trust's  principal  underwriter,  PIMCO Funds
Distributors LLC (the "Distributor"),  and through other firms which have dealer
agreements with the Distributor  ("participating  brokers") or which have agreed
to act as introducing brokers for the Distributor ("introducing brokers").

         There  are two ways to  purchase  Class A,  Class B or Class C  shares:
either 1) through  your dealer or broker which has a dealer  agreement  with the
Distributor;  or 2) directly by mailing a PIMCO Funds account  application  (the
"account application") with payment, as described below under the heading Direct
Investment,   to  the  Distributor  (if  no  dealer  is  named  in  the  account
application, the Distributor may act as dealer).

         Class A, Class B and Class C shares may be  purchased  at a price equal
to their net asset value per share next  determined  after  receipt of an order,
plus a sales  charge  which,  at the election of the  purchaser,  may be imposed
either  (i) at the time of the  purchase  in the  case of  Class A  shares  (the
"initial sales charge alternative"),  (ii) on a contingent deferred basis in the
case of Class B shares (the "deferred  sales charge  alternative"),  or (iii) by
the  deduction  of an ongoing  asset based  sales  charge in the case of Class C
shares (the "asset based sales charge alternative").  In certain  circumstances,
Class A and Class C shares  are also  subject  to a  contingent  deferred  sales
charge ("CDSC"). See "Alternative Purchase  Arrangements." Purchase payments for
Class B and  Class C shares  are fully  invested  at the net  asset  value  next
determined after acceptance of the trade.  Purchase payments for Class A shares,
less the  applicable  sales  charge,  are  invested  at the net asset value next
determined after acceptance of the trade.
<PAGE>


         All purchase orders  received by the Distributor  prior to the close of
regular  trading  (normally  4:00  p.m.,  Eastern  time) on the New  York  Stock
Exchange  (the  "Exchange"),  on a regular  business  day, are processed at that
day's offering price.  However,  orders received by the Distributor from dealers
or brokers  after the offering  price is  determined  that day will receive such
offering  price if the orders  were  received  by the dealer or broker  from its
customer prior to such determination and were transmitted to and received by the
Distributor prior to its close of business that day (normally 5:00 p.m., Eastern
time) or, in the case of certain  retirement plans,  received by the Distributor
prior to 9:30 a.m.,  Eastern  time on the next  business  day.  Purchase  orders
received  on other  than a regular  business  day will be  executed  on the next
succeeding  regular business day. The Distributor,  in its sole discretion,  may
accept or reject any order for purchase of Municipal Bond Fund shares.  The sale
of shares will be  suspended  during any period in which the  Exchange is closed
for  other  than  weekends  or  holidays,  or if  permitted  by the rules of the
Securities and Exchange  Commission,  when trading on the Exchange is restricted
or during an emergency which makes it impracticable  for the Municipal Bond Fund
to dispose of its securities or to determine fairly the value of its net assets,
or  during  any  other  period  as  permitted  by the  Securities  and  Exchange
Commission for the protection of investors.

         Except for purchases through the PIMCO Auto Invest plan, the PIMCO Auto
Exchange  plan,  investments  pursuant to the Uniform  Gifts to Minors Act,  and
tax-qualified  and  wrap  programs   referred  to  below  under   "Tax-Qualified
Retirement Plans" and "Sales at Net Asset Value", the minimum initial investment
in Class A,  Class B or Class C shares of any Fund of the Trust or any series of
PIMCO  Funds:  Multi-Manager  Series  is  $2,500,  and  the  minimum  additional
investment  is $100 per Fund.  For  information  about dealer  commissions,  see
"Alternative  Purchase  Arrangements" below. Persons selling Municipal Bond Fund
shares may receive different  compensation for selling Class A, Class B or Class
C shares.  Normally,  Municipal Bond Fund shares purchased through participating
brokers  are  held  in  the  investor's  account  with  that  broker.  No  share
certificates  will be issued  unless  specifically  requested  in  writing by an
investor or broker-dealer.

         Direct Investment

         Investors  who wish to invest in Class A,  Class B or Class C shares of
the Municipal Bond Fund directly,  rather than through a  participating  broker,
may do so by opening an account  with the  Distributor.  To open an account,  an
investor  should complete the account  application.  All  shareholders  who open
direct  accounts  with  the  Distributor   will  receive  from  the  Distributor
individual  confirmations of each purchase,  redemption,  dividend reinvestment,
exchange or transfer of Trust shares, including the total number of Trust shares
owned as of the confirmation  date,  except that purchases which result from the
reinvestment of daily-accrued  dividends and/or  distributions will be confirmed
once each calendar quarter.  See "Distributions"  below.  Information  regarding
direct  investment  or any other  features or plans  offered by the Trust may be
obtained by calling the Distributor at 800-426-0107 or by calling your broker.

         Purchase by Mail

         Investors who wish to invest directly may send a check payable to PIMCO
Funds Distributors LLC, along with a completed application form to:

                            PIMCO Funds Distributors LLC
                            P.O. Box 5866
                            Denver, CO 80217-5866
<PAGE>

         Purchases  are accepted  subject to  collection of checks at full value
and conversion into federal funds. Payment by a check drawn on any member of the
Federal  Reserve  System can normally be converted into federal funds within two
business days after receipt of the check.  Checks drawn on a non-member bank may
take up to 15 days to convert into  federal  funds.  In all cases,  the purchase
price is based on the net asset value next  determined  after the purchase order
and check are  accepted,  even though the check may not yet have been  converted
into federal funds.

         Subsequent Purchases of Shares

         Subsequent  purchases of Class A, Class B or Class C shares can be made
as indicated above by mailing a check with a letter describing the investment or
with the additional investment portion of a confirmation  statement.  Except for
subsequent  purchases  through the PIMCO Funds Auto-Invest plan, the PIMCO Funds
Auto-Exchange plan, tax-qualified programs and PIMCO Funds Fund Link referred to
below, and except during periods when an Automatic Withdrawal plan is in effect,
the minimum subsequent purchase is $100 in any Fund. All payments should be made
payable  to  PIMCO  Funds  Distributors  LLC and  should  clearly  indicate  the
shareholder's account number. Checks should be mailed to the address above under
"Purchase by Mail."

         Tax-Qualified Retirement Plans

         The Distributor makes available  retirement plan services and documents
for Individual Retirement Accounts (IRAs),  including Roth IRAs, for which First
National Bank of Boston serves as trustee and for IRA accounts  established with
Form  5305-SIMPLE  under the  Internal  Revenue  Code.  These  accounts  include
Simplified Employee Pension Plan (SEP) and Salary Reduction  Simplified Employee
Pension  Plan  (SAR/SEP)  IRA  accounts and  prototype  documents.  In addition,
prototype documents are available for establishing  403(b)(7) Custodial Accounts
with First National Bank of Boston as custodian.  This type of plan is available
to employees of certain non-profit organizations.

         The   Distributor   also  makes  available   prototype   documents  for
establishing  Money Purchase  and/or Profit Sharing Plans and 401(k)  Retirement
Savings Plans. Investors should call the Distributor at 800-426-0107 for further
information  about these plans and should  consult  with their own tax  advisers
before  establishing any retirement plan.  Investors who maintain their accounts
with  participating  brokers  should consult their broker about similar types of
accounts that may be offered through the broker.  The minimum initial investment
for all tax qualified plans (except for  employer-sponsored  plans, SIMPLE IRAs,
SEPs and SAR/SEPs) is $1,000 per Fund and the minimum  subsequent  investment is
$100 and the minimum initial  investment for  employer-sponsored  plans,  SIMPLE
IRAs, SEPs and SAR/SEPs and the minimum  subsequent  investment per Fund for all
such plans is $50.

         PIMCO Funds Auto-Invest

         The PIMCO Funds Auto-Invest plan provides for periodic investments into
the  shareholder's  account with the Trust by means of automatic  transfers of a
designated amount from the shareholder's  bank account.  The minimum  investment
for  eligibility  in the  PIMCO  Funds  Auto-Invest  Plan is  $1,000  per  Fund.
Subsequent  investments  may be made  monthly  or  quarterly,  and may be in any
amount  subject to a minimum of $50 per month for each Fund in which  shares are
purchased  through  the plan.  Further  information  regarding  the PIMCO  Funds
Auto-Invest plan is available from the Distributor or participating brokers. You
may enroll by completing the appropriate section on the account application,  or
you may obtain an  Auto-Invest  Application  by calling the  Distributor or your
broker.

         PIMCO Funds Auto-Exchange

         The  PIMCO  Funds  Auto-Exchange  plan  establishes  regular,  periodic
exchanges from one Fund to another Fund or a series of MMS which offers Class A,
Class B or Class C shares.  The plan  provides  for regular  investments  into a
shareholder's  account in a specific  Fund by means of automatic  exchanges of a
designated amount from another Fund account of the same class of shares and with
identical account registration.

         Exchanges  may be made monthly or  quarterly,  and may be in any amount
subject to a minimum of $50 for each Fund whose shares are purchased through the
plan.  Further  information  regarding  the PIMCO  Funds  Auto-Exchange  plan is
available from the Distributor at 800-426-0107 or participating brokers. You may
enroll by completing an application  which may be obtained from the  Distributor
or by telephone request at 800-426-0107.  For more information on exchanges, see
"Exchange Privilege."

         PIMCO Funds Fund Link

         PIMCO Funds Fund Link ("Fund  Link")  connects your Fund account with a
bank account. Fund Link may be used for subsequent purchases and for redemptions
and other  transactions  described under "How to Redeem." Purchase  transactions
are effected by electronic funds transfers from the  shareholder's  account at a
U.S. bank or other  financial  institution  that is an Automated  Clearing House
("ACH")  member.  Investors  may use Fund Link to make  subsequent  purchases of
shares  in  amounts  from $50 to  $10,000.  To  initiate  such  purchases,  call
800-426-0107. All such calls will be recorded. Fund Link is normally established
within 45 days of receipt of a Fund Link  Application by  Shareholder  Services,
Inc.  (the  "Transfer  Agent").  The minimum  investment by Fund Link is $50 per
Fund.  Shares will be  purchased  on the regular  business  day the  Distributor
receives  the funds  through the ACH  system,  provided  the funds are  received
before the close of regular  trading on the Exchange.  If the funds are received
after the close of regular  trading,  the shares will be  purchased  on the next
regular  business  day.  

         Fund Link privileges must be requested on the account  application.  To
establish Fund Link on an existing  account,  complete a Fund Link  Application,
which  is  available  from  the  Distributor  or your  broker,  with  signatures
guaranteed  from all  shareholders  of record for the  account.  See  "Signature
Guarantee"  below.  Such privileges  apply to each shareholder of record for the
account unless and until the Distributor  receives written  instructions  from a
shareholder  of  record  canceling  such  privileges.  Changes  of bank  account
information must be made by completing a new Fund Link Application signed by all
owners  of  record  of  the  account,  with  all  signatures   guaranteed.   The
Distributor,  the  Transfer  Agent and the  Municipal  Bond Fund may rely on any
telephone  instructions  believed to be genuine and will not be  responsible  to
shareholders for any damage,  loss or expenses arising out of such instructions.
The Municipal Bond Fund reserves the right to amend, suspend or discontinue Fund
Link  privileges at any time without  prior notice.  Fund Link does not apply to
shares held in broker "street name" accounts.
<PAGE>

         Signature Guarantee

         When a signature  guarantee is called for, the shareholder  should have
"Signature  Guaranteed" stamped under his signature and guaranteed by any of the
following entities:  U.S. banks, foreign banks having a U.S. correspondent bank,
credit  unions,  savings  associations,  U.S.  registered  dealers and  brokers,
municipal  securities  dealers and brokers,  government  securities  dealers and
brokers,  national securities exchanges,  registered securities associations and
clearing agencies (each an "Eligible  Guarantor  Institution").  The Distributor
reserves  the right to reject any  signature  guarantee  pursuant to its written
signature guarantee standards or procedures,  which may be revised in the future
to permit it to reject signature guarantees from Eligible Guarantor Institutions
that do not,  based on credit  guidelines,  satisfy  such  written  standards or
procedures.  The Trust may change the signature guarantee requirements from time
to time  upon  notice to  shareholders,  which may be given by means of a new or
supplemented Prospectus.

         Account Registration Changes

         Changes in registration or account privileges may be made in writing to
the  Transfer  Agent.  Signature  guarantees  may be  required.  See  "Signature
Guarantee" above. All correspondence must include the account number and must be
sent to: 

                          PIMCO Funds Distributors LLC
                          P.O. Box 5866
                          Denver, CO 80217-5866

         Small Account Fee

         Because of the disproportionately high costs of servicing accounts with
low  balances,  a fee at an  annual  rate of $16,  paid  to  Pacific  Investment
Management,  the Municipal  Bond Fund's  administrator,  will  automatically  be
deducted from direct accounts with balances  falling below a minimum level.  The
valuation  of accounts and the  deduction  are expected to take place during the
last five days of each calendar  quarter.  The fee will be deducted in quarterly
installments from accounts with balances below $2,500 except for Uniform Gift to
Minors, IRA, Roth IRA and Auto-Invest  accounts,  for which the limit is $1,000.
The fee will not apply to  employer-sponsored  retirement  accounts or 403(b)(7)
custodial accounts.  (A separate custodial fee may also apply to IRAs, Roth IRAs
and other  retirement  accounts.)  No small  account  fee will be charged on any
account of a  shareholder  if the  aggregate  value of all of the  shareholder's
accounts  is  at  least  $50,000.  No  fee  will  be  charged  to  employee  and
employee-related accounts of PIMCO Advisors and/or its affiliates.
<PAGE>

         Minimum Account Size

         Due to  the  relatively  high  cost  to  the  Municipal  Bond  Fund  of
maintaining  small accounts,  you are asked to maintain an account balance of at
least the amount necessary to open the type of account involved. If your balance
is below such  minimum for three  months or longer,  the  Municipal  Bond Fund's
administrator  shall have the right  (except  in the case of  employer-sponsored
retirement  accounts) to close your account after giving you 60 days in which to
increase your  balance.  Your account will not be liquidated if the reduction in
size is due solely to market  decline in the value of your Fund shares or if the
aggregate value of all your accounts in PIMCO Funds exceeds $50,000.

ALTERNATIVE PURCHASE ARRANGEMENTS
   
         Class A,  Class B and Class C shares  bear sales  charges in  different
forms and amounts and which bear different levels of expenses.  Through separate
prospectuses, the Municipal Bond Fund offers three additional classes of shares:
Class D,  Institutional  Class shares and Administrative  Class shares.  Class D
shares are offered  primarily through  financial  intermediaries.  Institutional
Class  shares and  Administrative  Class  share are sold to  pension  and profit
sharing plans, employee benefit plans, endowments, foundations, corporations and
other high net worth individuals.  Institutional Class, Administrative Class and
Class D shares are sold without sales charges and have  different  expenses than
Class A, Class B and Class C shares.  As a result of lower sales charges  and/or
operating expenses, Institutional Class, Administrative Class and Class D shares
are generally  expected to achieve higher investment returns than Class A, Class
B or Class C shares. To obtain more information about the other classes,  please
call the  Distributor at  800-927-4648  (for  Institutional  and  Administrative
Classes) or 888-87-PIMCO (for Class D).
    
         The alternative  purchase  arrangements are designed to enable a retail
investor to choose the method of purchasing  Municipal  Bond Fund shares that is
most  beneficial to the investor  based on all factors to be  considered,  which
include: the amount and intended length of the investment;  the particular Fund;
and whether the investor  intends to exchange  shares for shares of other Funds.
Generally,  when making an investment  decision,  investors  should consider the
anticipated  life of an intended  investment  in the  Municipal  Bond Fund,  the
accumulated  distribution  and  servicing  fees plus CDSCs on Class B or Class C
shares,  the initial  sales charge plus  accumulated  servicing  fees on Class A
shares  (plus  a CDSC  in  certain  circumstances),  the  possibility  that  the
anticipated  higher  return on Class A shares due to the lower  ongoing  charges
will  offset  the  initial  sales  charge  paid on such  shares,  the  automatic
conversion  of Class B shares to Class A shares and the  difference in the CDSCs
applicable to Class A, Class B and Class C shares.

         Class A The  initial  sales  charge  alternative  (Class  A)  might  be
preferred  by  investors  purchasing  shares of  sufficient  aggregate  value to
qualify for  reductions in the initial  sales charge  applicable to such shares.
Similar  reductions  are not available on the  contingent  deferred sales charge
alternative  (Class B) or the asset based sales  charge  alternative  (Class C).
Class A  shares  are  subject  to a  servicing  fee but  are  not  subject  to a
distribution   fee  and,   accordingly,   such   shares  are   expected  to  pay
correspondingly higher dividends on a per share basis. However,  because initial
sales  charges are  deducted at the time of  purchase,  not all of the  purchase
payment  for Class A shares is  invested  initially.  Class B and Class C shares
might be preferable to investors who wish to have all purchase payments invested
initially,  although remaining subject to higher distribution and servicing fees
and, for certain periods, being subject to a CDSC. An investor who qualifies for
an elimination of the Class A initial sales charge should also consider  whether
he or she anticipates  redeeming shares in a time period which will subject such
shares   to  a  CDSC   as   described   below.   See   "Initial   Sales   Charge
Alternative--Class A Shares--Class A Deferred Sales Charge" below.
<PAGE>

         Class B Class B shares might be  preferred  by investors  who intend to
invest in the  Municipal  Bond Fund for longer  periods and who do not intend to
purchase  shares of  sufficient  aggregate  value to  qualify  for sales  charge
reductions  applicable to Class A shares. Both Class B and Class C shares can be
purchased at net asset value without an initial sales  charge.  However,  unlike
Class C shares, Class B shares convert into Class A shares after the shares have
been held for seven years.  After the conversion takes place, the shares will no
longer be subject to a CDSC,  and will be subject to the servicing  fees charged
for Class A shares  which are lower than the  distribution  and  servicing  fees
charged  on  either  Class B or  Class C  shares.  See  "Deferred  Sales  Charge
Alternative--Class  B  Shares"  below.  Class B  shares  are not  available  for
purchase by employer sponsored retirement plans.

         Class C Class C shares might be  preferred  by investors  who intend to
purchase shares which are not of sufficient aggregate value to qualify for Class
A sales  charges  of 1% or less  and who  wish  to have  all  purchase  payments
invested  initially.  Class C  shares  are  preferable  to  Class B  shares  for
investors who intend to maintain their investment for  intermediate  periods and
therefore  may also be  preferable  for investors who are unsure of the intended
length  of their  investment.  Unlike  Class B  shares,  Class C shares  are not
subject to a CDSC after they have been held for one year and are subject to only
a 1% CDSC during the first year. However,  because Class C shares do not convert
into  Class A  shares,  Class B shares  are  preferable  to  Class C shares  for
investors who intend to maintain their investment in the Municipal Bond Fund for
long periods. See "Asset Based Sales Charge Alternative--Class C Shares" below.

         In determining  which class of shares to purchase,  an investor  should
always  consider  whether any waiver or reduction of a sales charge or a CDSC is
available. See generally "Initial Sales Charge  Alternative--Class A Shares" and
"Waiver of Contingent Deferred Sales Charges" below.

         The maximum  single  purchase of Class B shares of the Trust and series
of PIMCO Funds:  Multi-Manager  Series accepted is $249,999.  The maximum single
purchase of Class C shares of the Trust and series of PIMCO Funds: Multi-Manager
Series  accepted is $999,999.  The  Municipal  Bond Fund may refuse any order to
purchase shares.

         For  a  description  of  the   Distribution  and  Servicing  Plans  and
distribution  and  servicing  fees payable  thereunder  with respect to Class A,
Class B and Class C shares,  see  "Distributor  and  Distribution  and Servicing
Plans" below.
<PAGE>

relevant  prospectus;  (ix) involuntary  redemptions caused by operation of law;
(x) redemption of shares of any PIMS Fund (including the Municipal Bond Fund) if
it is combined  with  another  Fund,  investment  company,  or personal  holding

transaction;  (xi)  redemptions  by a shareholder  who is a  participant  making
periodic  purchases  of not less than $50  through  certain  employer  sponsored
savings plans that are clients of a broker-dealer with which the Distributor has
an  agreement  with respect to such  purchases;  (xii)  redemptions  effected by
trustees or other  fiduciaries who have purchased shares for employer  sponsored

with respect to such  purchases;  or (xiii)  redemptions in connection  with IRA
accounts established with Form 5305-SIMPLE under the Code for which the Trust is
the designated financial institution.
    
         The CDSC  applicable  to Class B shares  is  currently  waived  for any
partial or complete redemption in each of the following cases: (a) in connection
with a  distribution  without  penalty  under  Section  72(t) of the Code from a
403(b)(7)  plan or an IRA (with the exception of a Roth IRA) upon  attaining age
591/2;  (b)  following  death  or  disability  (as  defined  in the  Code)  of a

spouse) from an account in which the deceased or disabled is named, provided the
redemption is requested within one year of the death or initial determination of
disability;  and (c) up to 10% per year of the value of an account which (i) has
a value of at least $100,000 at the start of such year and (ii) is subject to an
Automatic Withdrawal Plan. See "How to Redeem--Automatic Withdrawal Plan."
<PAGE>

         The Distributor may require  documentation  prior to waiver of the CDSC
for  any  class,   including   distribution   letters,   certification  by  plan
administrators,   applicable   tax  forms,   death   certificates,   physicians'
certificates, etc.

         Initial Sales Charge Alternative -- Class A Shares

         Class A shares of the Municipal Bond Fund are sold at a public offering
price equal to their net asset value per share plus a sales charge, as set forth
below.  As  indicated  below  under  "Class A Deferred  Sales  Charge,"  certain
investors that purchase  $1,000,000 or more of the Municipal Bond Fund's Class A
shares  (and thus pay no initial  sales  charge)  may be subject to a 1% CDSC if
they redeem such shares during the first 18 months after their purchase.

         charge on such purchase.  However,  purchasers of $1,000,000 or more of
         Class A shares  (other  than those  purchasers  described  below  under
         "Sales at Net Asset Value" where no commission is paid) will be subject
         to a CDSC of 1% if such shares are redeemed  during the first 18 months
         after such shares are purchased unless such purchaser is eligible for a
         waiver of the CDSC as described  under "Waiver of  Contingent  Deferred
         Sales Charges" above. See "Class A Deferred Sales Charge" below.

         2. The Distributor will pay a commission to dealers who sell amounts of
         $1,000,000 or more of Class A shares (or who sell Class A shares at net
         asset value to certain  employer-sponsored  plans as outlined in "Sales
         at Net Asset  Value")  of the  Municipal  Bond Fund,  according  to the
         following schedule:  0.50% of the first $2,000,000 and 0.25% of amounts
         over $2,000,000.


         The  Municipal  Bond Fund  receives  the entire net asset  value of its
Class A shares purchased by investors. The Distributor receives the sales charge
shown  above  less  any  applicable   discount  or  commission   "reallowed"  to
participating  brokers  in  the  amounts  indicated  in  the  table  above.  The
Distributor  may,  however,   elect  to  reallow  the  entire  sales  charge  to
participating brokers for all sales with respect to which orders are placed with
the Distributor for the Municipal Bond Fund during a particular  period.  During
such  periods as may from time to time be  designated  by the  Distributor,  the
Distributor will pay an additional amount of up to .50% of the purchase price on
sales of Class A shares of all or selected Funds purchased to each participating
broker which obtains purchase orders in amounts exceeding thresholds established
from time to time by the Distributor.  From time to time, the  Distributor,  its
parent  and/or  its  affiliates  may  make  additional  payments  to one or more
participating  brokers  based  upon  factors  such as the  level of sales or the
length of time clients' assets have remained in the Trust.
<PAGE>

         Shares  issued  pursuant  to  the  automatic   reinvestment  of  income
dividends or capital gains  distributions  are issued at net asset value and are
not subject to any sales charges.

         Under the circumstances  described below,  investors may be entitled to
pay reduced sales charges for Class A shares.

         Combined Purchase  Privilege  Investors may qualify for a reduced sales
charge by  combining  purchases  of the  Class A shares of one or more  Funds or
series of MMS which offer Class A shares (together, "eligible PIMCO Funds") into
a "single purchase," if the resulting purchase totals at least $50,000. The term
single purchase refers to:

         (i)      a single purchase by an individual,  or concurrent  purchases,
                  which in the  aggregate  are at least equal to the  prescribed
                  amounts,  by an  individual,  his  or  her  spouse  and  their
                  children under the age of 21 years  purchasing  Class A shares
                  of the eligible PIMCO Funds for his, her or their own account;

         (ii)     a single purchase by a trustee or other  fiduciary  purchasing
                  shares  for  a  single  trust,  estate  or  fiduciary  account
                  although more than one beneficiary is involved; or

         (iii)    a single  purchase  for the  employee  benefit  plans of a 
                  single employer.

         For further  information,  call the Distributor at 800-426-0107 or your
broker.

         Cumulative  Quantity  Discount  (Right of  Accumulation)  A purchase of
additional  Class  A  shares  of any  eligible  PIMCO  Fund  may  qualify  for a
Cumulative  Quantity  Discount at the rate  applicable  to the discount  bracket
obtained by adding:

         (i)      the investor's current purchase;

         (ii)     the value (at the close of  business on the day of the current
                  purchase)  of all Class A shares of any  eligible  PIMCO  Fund
                  (other  than  the  Money  Market  Fund)  held by the  investor
                  computed at the maximum offering price; and

         (iii)    the value of all shares  described in paragraph  (ii) owned by
                  another   shareholder   eligible  to  be  combined   with  the
                  investor's  purchase into a "single purchase" as defined above
                  under "Combined Purchase Privilege."

         Letter of Intent An investor may also obtain a reduced  sales charge by
means of a written Letter of Intent,  which expresses an intention to invest not
less than $50,000 within a period of 13 months in Class A shares of any eligible
PIMCO Fund(s) (other than the Money Market Fund of the Trust).  Each purchase of
shares  under a Letter of Intent  will be made at the public  offering  price or
prices  applicable at the time of such purchase to a single  transaction  of the
dollar amount  indicated in the Letter.  At the investor's  option,  a Letter of
Intent may include purchases of Class A shares of any eligible PIMCO Fund (other
than the Money Market Fund of the Trust) made not more than 90 days prior to the
date the Letter of Intent is signed;  however,  the 13-month period during which
the Letter is in effect  will begin on the date of the  earliest  purchase to be
included and the sales charge on any  purchases  prior to the Letter will not be
adjusted.
<PAGE>

         Investors  qualifying  for the Combined  Purchase  Privilege  described
above may purchase  shares of the eligible  PIMCO Funds under a single Letter of
Intent.  For  example,  if at the time you sign a Letter  of Intent to invest at
least $100,000 in Class A shares of any Fund (other than the Money Market Fund),
you and your  spouse  each  purchase  Class A shares of the Global  Bond Fund II
worth  $30,000 (for a total of  $60,000),  it will only be necessary to invest a
total of $40,000  during the following 13 months in Class A shares of any of the
Funds  (other than the Money  Market Fund of the Trust) to qualify for the 3.50%
sales charge on the total amount being invested (the sales charge  applicable to
an  investment  of $100,000 in any of the Funds other than the Real Return Bond,
Low Duration,  Municipal Bond, Short-Term,  Money Market and StocksPLUS Funds of
the Trust).

         A Letter of Intent is not a binding  obligation  to  purchase  the full
amount indicated.  The minimum initial investment under a Letter of Intent is 5%
of such amount.  Shares  purchased with the first 5% of such amount will be held
in escrow (while  remaining  registered  in your name) to secure  payment of the
higher sales charge applicable to the shares actually purchased in the event the
full  intended  amount is not  purchased.  If the full amount  indicated  is not
purchased,  a sufficient  amount of such escrowed  shares will be  involuntarily
redeemed to pay the additional  sales charge  applicable to the amount  actually
purchased,  if necessary.  Dividends on escrowed shares, whether paid in cash or
reinvested in additional  eligible PIMCO Fund shares, are not subject to escrow.
When the full amount indicated has been purchased, the escrow will be released.

         If you wish to enter into a Letter of Intent in  conjunction  with your
initial  investment  in Class A shares of the  Municipal  Bond Fund,  you should
complete  the  appropriate  portion  of the  account  application.  If you are a
current Class A shareholder  desiring to enter into a Letter of Intent,  you can
obtain a form of Letter of Intent by contacting the  Distributor at 800-426-0107
or any broker participating in this program.

         Reinstatement  Privilege A Class A shareholder  of the  Municipal  Bond
Fund who has caused any or all of his shares to be redeemed  may reinvest all or
any portion of the  redemption  proceeds in Class A shares of any eligible PIMCO
Fund  at  net  asset  value  without  any  sales  charge,   provided  that  such
reinvestment is made within 120 calendar days after the redemption or repurchase
date.  Shares are sold to a reinvesting  shareholder at the net asset value next
determined. See "How Net Asset Value is Determined." A reinstatement pursuant to
this privilege will not cancel the redemption transaction and, consequently, any
gain or loss so realized may be recognized for federal tax purposes  except that
no loss may be  recognized  to the extent that the  proceeds are  reinvested  in
shares of the Municipal  Bond Fund within 30 days. The  reinstatement  privilege
may be utilized by a shareholder only once, irrespective of the number of shares
redeemed,  except that the privilege may be utilized without limit in connection
with transactions whose sole purpose is to transfer a shareholder's  interest in
the Municipal Bond Fund to his Individual  Retirement Account or other qualified
retirement plan account. An investor may exercise the reinstatement privilege by
written request sent to the Distributor or to the investor's broker.
<PAGE>

         Sales at Net Asset Value The  Municipal  Bond Fund may sell its Class A
shares at net asset  value  without a sales  charge to (a)  current  or  retired
officers,  trustees,  directors or employees  of the Trust,  Pacific  Investment
Management or the Distributor,  a parent, brother or sister of any such officer,
trustee,  director  or  employee  or a spouse  or child of any of the  foregoing
persons,  or any trust,  profit  sharing or pension  plan for the benefit of any
such person and to any other person if the  Distributor  anticipates  that there
will be minimal sales expenses  associated with the sale, (b) current or retired
trustees of MMS,  (c) current  registered  representatives  and other  full-time
employees  of  participating  brokers or such  persons'  spouses or for trust or
custodial  accounts for their minor children,  (d) trustees or other fiduciaries
purchasing  shares for certain  employer  sponsored plans that have at least 100
eligible  participants or at least $1 million in total plan assets, (e) trustees
or other fiduciaries purchasing shares for certain plans sponsored by employers,
professional  organizations or associations,  or charitable  organizations,  the
trustee,   administrator,   fiduciary,   broker,  trust  company  or  registered
investment  adviser for which has an agreement with the Distributor with respect
to  such  purchases,  and to  participants  in  such  plans  and  their  spouses
purchasing for their  accounts(s) or IRAs (with the exception of Roth IRAs), (f)
participants  investing  through  accounts known as "wrap accounts"  established
with  brokers or  dealers  approved  by the  Distributor  where such  brokers or
dealers are paid a single, inclusive fee for brokerage and investment management
services,  (g)  client  accounts  of  broker-dealers  or  registered  investment
advisers  affiliated with such  broker-dealers with which the Distributor has an
agreement  for the use of  PIMCO  Funds in  particular  investment  products  or
programs,  and (h) accounts for which a trust company  affiliated with the Trust
or Pacific  Investment  Management serves as trustee or custodian.  As described
above, the Distributor  will not pay any initial  commission to dealers upon the
sale of Class A shares to the purchasers  described in this paragraph except for
sales to purchasers described under (d) or (e) in this paragraph.

         Notification  of Distributor An investor or  participating  broker must
notify the Distributor  whenever a quantity  discount or reduced sales charge is
applicable  to a purchase  and must  provide  the  Distributor  with  sufficient
information  at the time of purchase to verify that each purchase  qualifies for
the privilege or discount. Upon such notification, the investor will receive the
lowest applicable sales charge.  The quantity  discounts  described above may be
modified or terminated at any time.

         Class A Deferred  Sales Charge For the Municipal  Bond Fund,  investors
who purchase  $1,000,000  or more of Class A shares (and,  thus,  purchase  such
shares without any initial sales charge) may be subject to a 1% CDSC (the "Class
A CDSC") if such shares are  redeemed  within 18 months of their  purchase.  The
Class A CDSC does not apply to investors  purchasing  $1,000,000  or more of the
Municipal Bond Fund's Class A shares if such investors are otherwise eligible to
purchase  Class A shares  without any sales charge  because  they are  described
under "Sales at Net Asset Value" above.

         For purchases subject to the Class A CDSC, a 1% CDSC will apply for any
redemption  of such  Class A  shares  that  occurs  within  18  months  of their
purchase.  No CDSC will be  imposed if the shares  redeemed  have been  acquired
through the  reinvestment of dividends or capital gains  distributions or if the
amount  redeemed is derived from increases in the value of the account above the
amount of purchase  payments subject to the CDSC. In determining  whether a CDSC
is payable,  it is assumed that Class A shares acquired through the reinvestment
of dividends and  distributions  are redeemed first, and thereafter that Class A
shares  that have been held by an investor  for the  longest  period of time are
redeemed first.
<PAGE>

         The  Class  A CDSC is  currently  waived  in  connection  with  certain
redemptions as described above under "Alternative Purchase  Arrangements--Waiver
of Contingent  Deferred Sales Charges." For more  information  about the Class A
CDSC, call the Distributor at 800-426-0107.

         Participating   Brokers   Investment   dealers   and  other   financial
intermediaries  provide varying  arrangements  for their clients to purchase and
redeem Municipal Bond Fund shares.  Some may establish higher minimum investment
requirements  than set forth  above.  Firms may arrange  with their  clients for
other investment or administrative  services and may independently establish and
charge  transaction  fees and/or other  additional  amounts to their clients for
such services,  which charges would reduce clients' return.  Firms also may hold
Municipal  Bond Fund shares in nominee or street name as agent for and on behalf
of their customers.  In such instances,  the Trust's transfer agent will have no
information  with respect to or control over accounts of specific  shareholders.
Such  shareholders  may obtain access to their  accounts and  information  about
their  accounts only from their broker.  In addition,  certain  privileges  with
respect  to the  purchase  and  redemption  of  shares  or the  reinvestment  of
dividends may not be available through such firms. Some firms may participate in
a  program  allowing  them  access  to their  clients'  accounts  for  servicing
including,  without  limitation,  transfers of  registration  and dividend payee
changes; and may perform functions such as generation of confirmation statements
and disbursement of cash dividends. This Prospectus should be read in connection
with such firms' material regarding their fees and services.

         Deferred Sales Charge Alternative -- Class B Shares

         Class B shares are sold at their  current net asset  value  without any
initial sales charge. The full amount of an investor's  purchase payment will be
invested in shares of the Municipal Bond Fund. A CDSC will be imposed on Class B
shares of the Municipal Bond Fund if an investor  redeems an amount which causes
the current value of the investor's  account for the Municipal Bond Fund to fall
below the total dollar amount of purchase  payments subject to the CDSC,  except
that no CDSC is imposed if the shares  redeemed have been  acquired  through the
reinvestment  of  dividends  or  capital  gains  distributions  or if the amount
redeemed is derived from  increases in the value of the account above the amount
of  purchase  payments  subject to the CDSC. 

         Whether a CDSC is imposed and the amount of the CDSC will depend on the
number of years since the investor made a purchase  payment from which an amount
is being redeemed.  Purchases are subject to the CDSC according to the following
schedule:

                     Year Since Purchase       Percentage
                     Payment was Made          Contingent

                       *After the  seventh  year,  Class B shares  convert  into
Class A shares as described below.
<PAGE>

         In  determining  whether  a CDSC is  payable,  it is  assumed  that the
purchase  payment  from  which a  redemption  is made is the  earliest  purchase
payment from which a redemption or exchange has not already been fully effected.

         The  following  example will  illustrate  the  operation of the Class B
CDSC:

         Assume that an individual opens an account and makes a purchase payment
of  $10,000  for Class B shares of the  Municipal  Bond Fund and that six months
later the value of the investor's  account for the Municipal Bond Fund has grown
through investment performance and reinvestment of distributions to $11,000. The
investor  then may redeem up to $1,000 from that Fund  ($11,000  minus  $10,000)
without  incurring a CDSC. If the investor should redeem $3,000, a CDSC would be
imposed on $2,000 of the redemption (the amount by which the investor's  account
for the Fund was reduced below the amount of the purchase payment).  At the rate
of 5%, the Class B CDSC would be $100.

         In determining  whether an amount is available for  redemption  without
incurring  a CDSC,  the  purchase  payments  made for all  Class B shares in the
shareholder's  account  with the  Municipal  Bond Fund are  aggregated,  and the
current value of all such shares is aggregated. Any CDSC imposed on a redemption
of Class B shares is paid to the Distributor.

         Class B shares  are  subject to higher  distribution  fees than Class A
shares for a fixed period after their purchase,  after which they  automatically
convert to Class A shares and are no longer subject to such higher  distribution
fees. Class B shares of the Municipal Bond Fund automatically convert into Class
A shares after they have been held for seven years.

         For  sales of Class B shares  made  and  services  rendered  to Class B
shareholders, the Distributor intends to make payments to participating brokers,
at the time a shareholder purchases Class B shares, of 4% of the purchase amount
for the  Municipal  Bond Fund.  During such  periods as may from time to time be
designated by the Distributor,  the Distributor will pay selected  participating
brokers an  additional  amount of up to .50% of the  purchase  price on sales of
Class B shares of all or selected Funds purchased to each  participating  broker
which obtains purchase orders in amounts exceeding  thresholds  established from
time to time by the Distributor.

         The  Class  B CDSC is  currently  waived  in  connection  with  certain
redemptions as described above under "Alternative Purchase  Arrangements--Waiver
of Contingent  Deferred Sales Charges." For more  information  about the Class B
CDSC, call the Distributor at 800-426-0107.
<PAGE>

         Asset Based Sales Charge Alternative -- Class C Shares

         Class C shares are sold at their  current net asset  value  without any
initial sales charge.  A CDSC is imposed on Class C shares of the Municipal Bond
Fund if an investor  redeems an amount  which  causes the  current  value of the
investor's  account for the  Municipal  Bond Fund to fall below the total dollar
amount of purchase  payments subject to the CDSC, except that no CDSC is imposed
if the shares redeemed have been acquired  through the reinvestment of dividends
or capital  gains  distributions  or if the  amount  redeemed  is  derived  from
increases  in the value of the  account  above the amount of  purchase  payments
subject to the CDSC.  All of an  investor's  purchase  payments  are invested in
shares of the Fund(s) selected.

         Whether a CDSC is imposed and the amount of the CDSC will depend on the
number of years since the investor made a purchase  payment from which an amount
is being redeemed.  Purchases are subject to the CDSC according to the following
schedule:


                       Year Since Purchase    Percentage
                      Payment was Made       Contingent
                                             Deferred Sales Charge
                      ----------------------------------------------
                       First                  1
                      ----------------------------------------------
                       Thereafter             0

         In  determining  whether  a CDSC is  payable,  it is  assumed  that the
purchase  payment from which the  redemption  is made is the  earliest  purchase
payment (from which a redemption or exchange has not already been effected).

         The  following  example will  illustrate  the  operation of the Class C
CDSC:

         Assume that an individual opens an account and makes a purchase payment
of  $10,000  for Class C shares of the  Municipal  Bond Fund and that six months
later the value of the investor's  account for the Municipal Bond Fund has grown
through investment performance and reinvestment of distributions to $11,000. The
investor  then may redeem up to $1,000  from the  Municipal  Bond Fund  ($11,000
minus $10,000) without incurring a CDSC. If the investor should redeem $3,000, a
CDSC  would be  imposed  on $2,000 of the  redemption  (the  amount by which the
investor's  account  for the Fund was reduced  below the amount of the  purchase
payment). At the rate of 1%, the Class C CDSC would be $20.
   
         In determining  whether an amount is available for  redemption  without
incurring  a CDSC,  the  purchase  payments  made for all  Class C shares in the
shareholder's  account  with the  Municipal  Bond Fund are  aggregated,  and the
current value of all such shares is aggregated. Any CDSC imposed on a redemption
of Class C shares is paid to the  Distributor.  Unlike  Class B shares,  Class C
shares  do not  automatically  convert  to any  other  class  of  shares  of the
Municipal Bond Fund.
    
         Except  as  described  below,  for  sales of  Class C  shares  made and
services  rendered  to Class C  shareholders,  the  Distributor  expects to make
payments to participating brokers, at the time the shareholder purchases Class C
shares, of 1.00%  (representing  .75% distribution fees and .25% servicing fees)
of the purchase  amount for the Municipal Bond Fund. For sales of Class C shares
made to  participants  making  periodic  purchases  of not less than $50 through
certain  employer  sponsored  savings plans which are clients of a broker-dealer
with which the Distributor  has an agreement with respect to such purchases,  no
payments are made at the time of purchase.  During such periods as may from time
to time be designated by the Distributor, the Distributor will pay an additional
amount of up to .50% of the purchase  price on sales of Class C shares of all or
selected Funds  purchased to each  participating  broker which obtains  purchase
orders in  amounts  exceeding  thresholds  established  from time to time by the
Distributor.

         The  Class  C CDSC is  currently  waived  in  connection  with  certain
redemptions as described above under "Alternative Purchase  Arrangements--Waiver
of Contingent  Deferred Sales Charges." For more  information  about the Class C
CDSC, contact the Distributor at 800-426-0107.

EXCHANGE PRIVILEGE

         A shareholder  may exchange  Class A, Class B and Class C shares of the
Municipal Bond Fund for the same Class of shares of any other Fund in an account
with identical  registration on the basis of their  respective net asset values.
Class A,  Class B and  Class C shares  of the  Municipal  Bond  Fund may also be
exchanged  for shares of the same class of a series  which  offers such  classes
(except for the Opportunity Fund if a restriction applies) of MMS, an affiliated
mutual fund  family  comprised  primarily  of equity  portfolios  managed by the
subsidiary partnerships of PIMCO Advisors.  There are currently no exchange fees
or charges. Except with respect to tax-qualified programs and exchanges effected
through the PIMCO Funds Auto-Exchange plan,  exchanges are subject to the $2,500
minimum  initial  purchase  requirement for the Municipal Bond Fund. An exchange
will constitute a taxable sale for federal income tax purposes.

         Investors who maintain their account with the  Distributor may exchange
shares by a written exchange request sent to PIMCO Funds  Distributors LLC, P.O.
Box 5866,  Denver,  CO  80217-5866  or,  unless the  investor  has  specifically
declined telephone exchange  privileges on the account application or elected in
writing  not to  utilize  telephone  exchanges,  by a  telephone  request to the
Transfer Agent at 800-426-0107.  The Trust will employ reasonable  procedures to
confirm that  instructions  communicated  by telephone  are genuine,  and may be
liable for any losses due to unauthorized or fraudulent instructions if it fails
to  employ  such  procedures.   The  Trust  will  require  a  form  of  personal
identification  prior to  acting  on a  caller's  telephone  instructions,  will
provide written  confirmations  of such  transactions  and will record telephone

Shares--Signature Guarantee." Telephone exchanges may be made between 9:00 a.m.,
Eastern time and the close of regular trading (normally 4:00 p.m., Eastern time)
on the Exchange on any day the Exchange is open  (generally  weekdays other than
normal holidays).  The Trust reserves the right to refuse exchange purchases if,
in the judgment of Pacific Investment  Management,  the purchase would adversely
affect the Municipal Bond Fund and its shareholders. In particular, a pattern of
exchanges characteristic of "market-timing"  strategies may be deemed by Pacific
Investment  Management  to be  detrimental  to the Trust or a  particular  Fund.
Although the Trust has no current  intention  of  terminating  or modifying  the
exchange  privilege,  it  reserves  the  right to do so at any  time.  Except as
otherwise  permitted by SEC  regulations,  the Trust will give 60 days'  advance
notice to  shareholders  of any  termination  or  material  modification  of the
exchange privilege.  For further information about exchange privileges,  contact
your participating broker or call the Transfer Agent at 800-426-0107.

         With respect to Class B and Class C shares,  or Class A shares  subject
to a CDSC,  if less than all of an  investment is exchanged out of the Municipal
Bond Fund, any portion of the investment  attributable  to capital  appreciation
and/or  reinvested  dividends or capital gains  distributions  will be exchanged
first,  and  thereafter  any  portions  exchanged  will  be  from  the  earliest
investment  made in the  Municipal  Bond  Fund.  Shareholders  should  take into
account the effect of any exchange on the  applicability of any CDSC that may be
imposed upon any subsequent redemption.

         Investors  may also  select the PIMCO  Funds  Auto-Exchange  plan which
establishes  automatic periodic exchanges.  For further information on automatic
exchanges, see "How to Buy Shares--PIMCO Funds Auto-Exchange" above.

HOW TO REDEEM

         Class  A,  Class  B or  Class  C  shares  may  be  redeemed  through  a
participating  broker, by telephone,  by submitting a written redemption request
directly  to the  Transfer  Agent  (for  non-broker  accounts),  or  through  an
Automatic Withdrawal Plan or Fund Link.

         A CDSC may apply to a redemption of Class A, Class B or Class C shares.
See "Alternative Purchase  Arrangements" above. Shares are redeemed at their net
asset value next determined after a proper redemption request has been received,
less any applicable CDSC.  There is no charge by the Distributor  (other than an
applicable CDSC) with respect to a redemption;  however, a participating  broker
who processes a redemption for an investor may charge customary  commissions for
its  services.  Dealers and other  financial  services  firms are  obligated  to
transmit orders promptly.  Requests for redemption  received by dealers or other
firms prior to the close of regular trading  (normally 4:00 p.m.,  Eastern time)
on the Exchange on a regular business day and received by the Distributor  prior
to the close of the  Distributor's  business  day will be  confirmed  at the net
asset value  effective as of the closing of the  Exchange on that day,  less any
applicable CDSC.

         Direct Redemption

         A shareholder's original account application permits the shareholder to
redeem by written request and by telephone (unless the shareholder  specifically
elects not to  utilize  telephone  redemptions)  and to elect one or more of the
additional  redemption  procedures described below. A shareholder may change the
instructions  indicated  on his  original  account  application,  or may request
additional  redemption options,  only by transmitting a written direction to the
Transfer Agent. Requests to institute or change any of the additional redemption
procedures will require a signature guarantee. Redemption proceeds will normally
be mailed to the redeeming shareholder within seven days or, in the case of wire
transfer or Fund Link  redemptions,  sent to the designated  bank account within
one  business  day.  Fund Link  redemptions  may be  received by the bank on the
second or third business day. In cases where shares have recently been purchased
by personal check,  redemption proceeds may be withheld until the check has been
collected,  which may take up to 15 days. To avoid such  withholding,  investors
should purchase  shares by certified or bank check or by wire transfer.
<PAGE>

         Written Requests

         To  redeem   shares  in  writing   (whether  or  not   represented   by
certificates),  a  shareholder  must send the  following  items to the  Transfer
Agent,  Shareholder Services,  Inc., P.O. Box 5866, Denver, Colorado 80217-5866:
(1) a written request for redemption  signed by all registered owners exactly as
the account is registered on the Transfer Agent's records,  including  fiduciary
titles,  if any,  and  specifying  the account  number and the dollar  amount or
number of shares to be redeemed;  (2) for certain redemptions described below, a
guarantee of all signatures on the written  request or on the share  certificate
or  accompanying  stock  power,  if  required,  as  described  under "How to Buy
Shares--Signature  Guarantee";  (3) any share certificates issued for any of the
shares to be redeemed (see "Certificated  Shares" below); and (4) any additional
documents  which  may be  required  by the  Transfer  Agent  for  redemption  by
corporations,  partnerships or other organizations,  executors,  administrators,
trustees,  custodians or guardians,  or if the redemption is requested by anyone
other than the shareholder(s) of record.  Transfers of shares are subject to the
same  requirements.  A signature  guarantee is not required for  redemptions  of
$50,000 or less,  requested by and payable to all shareholders of record for the
account, to be sent to the address of record for that account. To avoid delay in
redemption  or  transfer,   shareholders   having  any  questions   about  these
requirements  should  contact  the  Transfer  Agent  in  writing  or by  calling
1-800-426-0107 before submitting a request. Redemption or transfer requests will
not be  honored  until  all  required  documents  in the  proper  form have been
received by the Transfer Agent.  This redemption option does not apply to shares
held in broker  "street name"  accounts.

         If the proceeds of the  redemption (i) exceed  $50,000,  (ii) are to be
paid to a person other than the record owner, (iii) are to be sent to an address
other than the address of the account on the Transfer Agent's  records,  or (iv)
are  to  be  paid  to  a  corporation,  partnership,  trust  or  fiduciary,  the
signature(s) on the redemption request and on the certificates, if any, or stock
power must be guaranteed as described  above,  except that the  Distributor  may
waive the signature  guarantee  requirement  for  redemptions  up to $2,500 by a
trustee of a  qualified  retirement  plan,  the  administrator  for which has an
agreement with the Distributor.

         Telephone Redemptions

         The Trust  accepts  telephone  requests  for  redemption  of shares for
amounts up to $50,000 within any 7 calendar day period, except for investors who
have  specifically  declined  telephone  redemption  privileges  on the  account
application  or elected in writing  not to utilize  telephone  redemptions.  The
proceeds of a telephone redemption will be sent to the record shareholder at his
record  address.  Changes  in  account  information  must be  made in a  written
authorization  with a  signature  guarantee.  See "How to Buy  Shares--Signature
Guarantee".  Telephone redemptions will not be accepted during the 30-day period
following any change in an account's record address. This redemption option does
not apply to shares held in broker "street name" accounts.
<PAGE>

         By  completing  an account  application,  an  investor  agrees that the
Trust,  the  Distributor and the Transfer Agent shall not be liable for any loss
incurred by the investor by reason of the Trust accepting unauthorized telephone
redemption  requests  for his  account  if the  Trust  reasonably  believes  the
instructions to be genuine. Thus, shareholders risk possible losses in the event
of a telephone redemption not authorized by them. The Trust may accept telephone
redemption  instructions from any person identifying  himself as the owner of an
account or the  owner's  broker  where the owner has not  declined in writing to
utilize this  service.  The Trust will employ  reasonable  procedures to confirm
that instructions  communicated by telephone are genuine,  and may be liable for
any losses due to unauthorized or fraudulent  instructions if it fails to employ
such procedures.  The Trust will require a form of personal identification prior
to  acting  on  a  caller's   telephone   instructions,   will  provide  written
confirmations of such transactions and will record telephone instructions.

         A shareholder  making a telephone  redemption  should call the Transfer
Agent at 800-426-0107 and state (i) the name of the shareholder as it appears on
the Transfer Agent's records,  (ii) his account number with the Trust, (iii) the
amount  to be  withdrawn  and  (iv)  the  name  of  the  person  requesting  the
redemption.  Usually  the  proceeds  are sent to the  investor on the next Trust
business day after the redemption is effected,  provided the redemption  request
is received prior to the close of regular trading  (normally 4:00 p.m.,  Eastern
time) on the Exchange that day. If the redemption  request is received after the
close of the  Exchange,  the  redemption  is  effected  on the  following  Trust
business  day at that day's net asset value and the proceeds are usually sent to
the investor on the second  following Trust business day. The Trust reserves the
right to  terminate  or modify  the  telephone  redemption  service at any time.
During times of severe  disruptions  in the  securities  markets,  the volume of
calls may make it difficult to redeem by telephone,  in which case a shareholder
may wish to send a written  request for  redemption as described  under "Written
Requests" above. Telephone  communications may be recorded by the Distributor or
the Transfer Agent.

         Fund Link Redemptions


         If a shareholder has established  Fund Link, the shareholder may redeem
shares  by  telephone  and have the  redemption  proceeds  sent to a  designated
account at a financial institution.  Fund Link is normally established within 45
days of receipt of a Fund Link  Application by the Transfer  Agent.  To use Fund
Link for redemptions,  call the Transfer Agent at  800-426-0107.  Subject to the
limitations set forth above under "Telephone Redemptions," the Distributor,  the
Trust and the Transfer Agent may rely on  instructions  by any registered  owner
believed to be genuine and will not be  responsible to any  shareholder  for any
loss, damage or expense arising out of such  instructions.  Requests received by
the Transfer  Agent prior to the close of regular  trading  (normally 4:00 p.m.,
Eastern  time) on the  Exchange on a business  day will be  processed at the net
asset value on that day and the proceeds  (less any CDSC) will  normally be sent
to the designated bank account on the following business day and received by the
bank on the second or third business day. If the redemption  request is received
after the close of regular  trading on the Exchange,  the redemption is effected
on the  following  business day.  Shares  purchased by check may not be redeemed
through  Fund Link until such  shares  have been owned  (i.e.,  paid for) for at
least 15 days.  Fund Link may not be used to redeem shares held in  certificated
form. Changes in bank account  information must be made by completing a new Fund
Link  Application,  signed by all  owners of  record  of the  account,  with all
signatures guaranteed. See "How to Buy Shares--Signature Guarantee." See "How to
Buy Shares--  PIMCO Funds Fund Link" for  information on  establishing  the Fund
Link  privilege.  The Trust may  terminate  the Fund  Link  program  at any time
without notice to shareholders.  This redemption option does not apply to shares
held in broker "street name" accounts.

PIMCO Funds Automated Telephone System

         PIMCO  Funds  Automated   Telephone  System  ("ATS")  is  an  automated
telephone  system  that  enables  shareholders  to  perform a number of  account
transactions  automatically  using a  touch-tone  telephone.  ATS may be used on
already-established  Fund  accounts  after you obtain a Personal  Identification
Number (PIN) by calling the special ATS number: 1-800-223-2413.

         Purchasing Shares. You may purchase shares in amounts up to $100,000 by
telephone by calling 1-800-223-2413. You must have established ATS privileges to
link your bank account with the Fund to pay for these purchases.

         Exchanging  Shares.  With the PIMCO Funds Exchange  Privilege,  you can
exchange  shares  automatically  by  telephone  from your Fund Link  Account  to
another   PIMCO  Funds   account  you  have  already   established   by  calling
1-800-223-2413. Please refer to "Exchange Privilege" below for details.

         Redemptions.  You may  redeem  shares  by  telephone  automatically  by
calling 1-800-223-2413 and the Fund will send the proceeds directly to your Fund
bank account. Please refer to "How to Redeem" below for details.

         Expedited Wire Transfer Redemptions

         If a shareholder has given authorization for expedited wire redemption,
shares can be  redeemed  and the  proceeds  sent by federal  wire  transfer to a
single previously designated bank account.  Requests received by the Trust prior
to the close of the Exchange  will result in shares being  redeemed  that day at
the next  determined  net asset value (less any CDSC) and  normally the proceeds
being sent to the designated  bank account the following  business day. The bank
must be a member of the Federal Reserve wire system. Delivery of the proceeds of
a wire  redemption  request  may be delayed by the Trust for up to 7 days if the
Distributor  deems it  appropriate  under then current market  conditions.  Once
authorization  is  on  file,  the  Trust  will  honor  requests  by  any  person
identifying  himself  as the  owner  of an  account  or the  owner's  broker  by
telephone  at  800-426-0107  or by  written  instructions.  The Trust  cannot be
responsible  for the  efficiency  of the  Federal  Reserve  wire  system  or the
shareholder's bank. The Trust does not currently charge for wire transfers.  The
shareholder is responsible  for any charges imposed by the  shareholder's  bank.
The minimum amount that may be wired is $2,500.  The Trust reserves the right to
change  this  minimum or to  terminate  the wire  redemption  privilege.  Shares
purchased by check may not be redeemed by wire  transfer  until such shares have
been  owned  (i.e.,  paid  for) for at least 15 days.  Expedited  wire  transfer
redemptions   may  be  authorized  by  completing  a  form  available  from  the
Distributor.  Wire  redemptions may not be used to redeem shares in certificated
form.  To change the name of the single bank account  designated to receive wire
redemption  proceeds,  it is necessary to send a written request with signatures
guaranteed  to  PIMCO  Funds   Distributors  LLC,  P.O.  Box  5866,  Denver,  CO
80217-5866.  See "How to Buy Shares --  Signature  Guarantee."  This  redemption
option does not apply to shares held in broker "street name" accounts.
<PAGE>

         Certificated Shares

         To  redeem  shares  for  which   certificates  have  been  issued,  the
certificates  must be mailed to or deposited  with the Trust,  duly  endorsed or
accompanied  by a  duly  endorsed  stock  power  or  by a  written  request  for
redemption.  Signatures  must  be  guaranteed  as  described  under  "How to Buy
Shares--Signature  Guarantee."  Further  documentation  may  be  requested  from
institutions or fiduciary  accounts,  such as  corporations,  custodians  (e.g.,
under the Uniform Gifts to Minors Act), executors,  administrators,  trustees or
guardians  ("institutional  account owners").  The redemption  request and stock
power must be signed exactly as the account is registered,  including indication
of any special capacity of the registered owner.

         Automatic Withdrawal Plan

         An investor who owns or buys shares of the Municipal Bond Fund having a
net asset  value of $10,000 or more may open an  Automatic  Withdrawal  Plan and
have a  designated  sum of money (not less than $100 per Fund) paid  monthly (or
quarterly) to the investor or another person.  Such a plan may be established by
completing the appropriate  section of the account application or you may obtain
an Automatic Withdrawal Plan Application from the Distributor or your broker. If
an  Automatic  Withdrawal  Plan  is set up  after  the  account  is  established
providing  for payment to a person  other than the record  shareholder  or to an
address other than the address of record, a signature guarantee is required. See
"How to Buy Shares--Signature Guarantee." Class A, Class B and Class C shares of
the Municipal  Bond Fund are  deposited in a plan account and all  distributions
are reinvested in additional  shares of that class of the Municipal Bond Fund at
net asset value.  Shares in a plan account are then  redeemed at net asset value
(less any applicable CDSC) to make each withdrawal payment.  Any applicable CDSC
may be waived for certain  redemptions  under an Automatic  Withdrawal Plan. See
"Alternative   Purchase   Arrangements--Waiver   of  Contingent  Deferred  Sales
Charges."  
<PAGE>

         Redemptions  for the purpose of withdrawals  are ordinarily made on the
business day  preceding the day of payment at that day's closing net asset value
and checks are mailed on the day of payment  selected  by the  shareholder.  The
Transfer  Agent may  accelerate the redemption and check mailing date by one day
to  avoid  weekend  delays.  Payment  will be made to any  person  the  investor
designates;  however,  if the shares are  registered in the name of a trustee or
other fiduciary,  payment will be made only to the fiduciary, except in the case
of a profit-sharing  or pension plan where payment will be made to the designee.
As  withdrawal  payments  may  include a return  of  principal,  they  cannot be
considered a guaranteed  annuity or actual yield of income to the investor.  The
redemption of shares in connection with an Automatic  Withdrawal Plan may result
in a gain or loss for tax purposes.  Continued  withdrawals  in excess of income
will reduce and possibly exhaust invested principal,  especially in the event of
a market decline.  The maintenance of an Automatic  Withdrawal Plan concurrently
with  purchases  of  additional  shares  of the  Municipal  Bond  Fund  would be
disadvantageous  to the investor  because of the CDSC that may become payable on
such  withdrawals  in the case of Class A, Class B or Class C shares and because
of the initial sales charge in the case of Class A shares.  For this reason, the
minimum  investment  accepted  for the  Municipal  Bond Fund while an  Automatic
Withdrawal  Plan is in effect  for the  Municipal  Bond Fund is  $1,000,  and an
investor may not maintain a plan for the accumulation of shares of the Municipal
Bond Fund (other than through  reinvestment of  distributions)  and an Automatic
Withdrawal  Plan at the same time. The Trust or the Distributor may terminate or
change the terms of the Automatic Withdrawal Plan at any time.

         Because the Automatic  Withdrawal Plan may involve invasion of capital,
investors  should consider  carefully with their own financial  advisers whether
the plan and the  specified  amounts to be withdrawn  are  appropriate  in their
circumstances.  The  Trust  and  the  Distributor  make  no  recommendations  or
representations in this regard.

DISTRIBUTOR AND DISTRIBUTION AND SERVICING PLANS

         The Distributor,  a wholly owned  subsidiary of PIMCO Advisors,  is the
principal  underwriter  of the  Trust's  shares  and in  that  connection  makes
distribution  and  servicing  payments to  participating  brokers and  servicing
payments to certain banks and other financial  intermediaries in connection with
the sale of Class B and Class C shares and servicing  payments to  participating
brokers, certain banks and other financial intermediaries in connection with the
sale of Class A shares.  In the case of Class A shares,  these  parties are also
compensated  based on the amount of the front-end sales charge  reallowed by the
Distributor,  except in cases where Class A shares are sold  without a front-end
sales  charge.  In the case of Class B shares,  participating  brokers and other
financial  intermediaries are compensated by an advance of a sales commission by
the Distributor.  In the case of Class C shares, part or all of the first year's
distribution  and servicing fee is generally paid at the time of sale.  Pursuant
to a  Distribution  Contract with the Trust,  with respect to the Municipal Bond
Fund's Class A, Class B and Class C shares,  the Distributor bears various other
promotional  and sales  related  expenses,  including  the cost of printing  and
mailing   prospectuses   to  persons  other  than  current   shareholders.   The
Distributor,  located at 2187 Atlantic Street, Stamford, Connecticut 06902, is a
broker-dealer registered with the SEC.

         Class A  Servicing  Fees As  compensation  for  services  rendered  and
expenses borne by the Distributor in connection with personal  services rendered
to Class A shareholders  of the Trust and the maintenance of Class A shareholder
accounts,  the Trust pays the Distributor  servicing fees up to the annual rates
of 0.25%  (calculated  as a percentage  of each Fund's  average daily net assets
attributable to Class A shares).

         Class B Distribution  and Servicing Fees As  compensation  for services
rendered  and  expenses  borne  by  the   Distributor  in  connection  with  the
distribution  of Class B shares of the Trust and, in  connection  with  personal
services  rendered to Class B shareholders  of the Trust and the  maintenance of
Class B shareholder accounts,  the Trust pays the Distributor servicing fees and
distribution  fees up to the  annual  rates set  forth  below  (calculated  as a
percentage  of each  Fund's  average  daily net assets  attributable  to Class B
shares):

distribution  of Class C shares of the Trust and, in  connection  with  personal
services  rendered to Class C shareholders  of the Trust and the  maintenance of
Class C shareholder accounts,  the Trust pays the Distributor servicing fees and
distribution  fees up to the  annual  rates set  forth  below  (calculated  as a
percentage of the Municipal Bond Fund's average daily net assets attributable to
Class C shares):

                          Distributor ceases to voluntarily waive any portion of
                          the fee.
    
         The Class A  servicing  fees and Class B and Class C  distribution  and
servicing fees paid to the Distributor are made under Distribution and Servicing
Plans  adopted  pursuant  to Rule  12b-l  under the 1940 Act and are of the type
known as  "compensation"  plans.  This means that,  although the Trustees of the
Trust are expected to take into account the expenses of the  Distributor and its
predecessors in their periodic review of the  Distribution  and Servicing Plans,
the fees are payable to compensate the Distributor for services rendered even if
the amount paid exceeds the Distributor's expenses.

         The  distribution  fee  applicable to Class B and Class C shares may be
spent by the  Distributor  on any activities or expenses  primarily  intended to
result  in the  sale of  Class  B or  Class C  shares,  respectively,  including
compensation to, and expenses  (including  overhead and telephone  expenses) of,
financial  consultants or other employees of the Distributor or of participating
or introducing  brokers who engage in distribution of Class B or Class C shares,
printing of prospectuses  and reports for other than existing Class B or Class C
shareholders,  advertising, and preparation,  printing and distribution of sales
literature. The servicing fee, applicable to Class A, Class B and Class C shares
of the Trust, may be spent by the Distributor on personal  services  rendered to
shareholders of the Trust and the maintenance of shareholder accounts, including
compensation to, and expenses  (including  telephone and overhead  expenses) of,
financial  consultants  or  other  employees  of  participating  or  introducing
brokers,  certain  banks  and  other  financial  intermediaries  who  aid in the
processing  of purchase or  redemption  requests or the  processing  of dividend
payments,  who provide  information  periodically to shareholders  showing their
positions  in a Fund's  shares,  who  forward  communications  from the Trust to
shareholders, who render ongoing advice concerning the suitability of particular
investment  opportunities  offered  by the  Trust in light of the  shareholders'
needs, who respond to inquiries from shareholders  relating to such services, or
who  train  personnel  in the  provision  of  such  services.  Distribution  and
servicing  fees  may  also  be  spent  on  interest   relating  to  unreimbursed
distribution or servicing expenses from prior years.
<PAGE>

         Many of the Distributor's sales and servicing efforts involve the Trust
as a whole,  so that  fees  paid by Class  A,  Class B or Class C shares  of the
Municipal Bond Fund may indirectly  support sales and servicing efforts relating
to the other Funds'  shares of the same class.  In reporting its expenses to the
Trustees,  the  Distributor  itemizes  expenses that relate to the  distribution
and/or  servicing of a single Fund's shares,  and allocates other expenses among
the Funds based on their  relative net assets.  Expenses  allocated to each Fund
are further allocated among its classes of shares annually based on the relative
sales of each  class,  except for any  expenses  that relate only to the sale or
servicing of a single class.  The  Distributor may make payments to brokers (and
with  respect to  servicing  fees only,  to  certain  banks and other  financial
intermediaries) of up to the following percentages annually of the average daily
net assets attributable to shares in the accounts of their customers or clients:

                      which no payment is made to the party at the time of sale.

         The  Distributor  may from time to time pay additional  cash bonuses or
other incentives to selected  participating  brokers in connection with the sale
or servicing of Class A, Class B and Class C shares of the Municipal  Bond Fund.
On some occasions,  such bonuses or incentives may be conditioned  upon the sale
of a specified  minimum  dollar amount of the shares of the Municipal  Bond Fund
and/or all of the Funds  together  or a  particular  class of  shares,  during a
specific period of time. The Distributor  currently expects that such additional
bonuses or  incentives  will not exceed .50% of the amount of any sale.  Pacific
Investment   Management  (in  its  capacity  as  administrator)   may  also  pay
participating  brokers and other  intermediaries  for transfer  agency and other
services.
<PAGE>

         If in any year the  Distributor's  expenses incurred in connection with
the  distribution  of Class B and Class C shares  and,  for Class A, Class B and
Class C  Shares,  in  connection  with the  servicing  of  shareholders  and the
maintenance of shareholder  accounts,  exceed the distribution  and/or servicing
fees paid by the Trust,  the  Distributor  would recover such excess only if the
Distribution  and Servicing Plan with respect to such class of shares  continues
to be in effect in some later year when the  distribution  and/or servicing fees
exceed  the  Distributor's  expenses.  The Trust is not  obligated  to repay any
unreimbursed  expenses  that may exist at such  time,  if any,  as the  relevant
Distribution and Servicing Plan terminates.

         From time to time,  expenses  of  principal  underwriters  incurred  in
connection  with the sale of  shares of the  Funds  and in  connection  with the
servicing  of  shareholders  of the Funds  and the  maintenance  of  shareholder
accounts  may  exceed the  distribution  and  servicing  fees  collected  by the
Distributor.  As of March 31, 1997, such expenses were approximately $430,000 in
excess of payments under the Funds' Class A Distribution  and Servicing Plan and
$1,192,000  in excess of  payments  under the Funds'  Class B  Distribution  and
Servicing  Plan.  Expenses  did not exceed  payments  under the  Funds'  Class C
Distribution and Servicing Plan.

HOW NET ASSET VALUE IS DETERMINED

         The net asset value per share of Class A, Class B and Class C shares of
the  Municipal  Bond  Fund  will be  determined  once on each day on  which  the
Exchange is open as of the close of regular trading (normally 4:00 p.m., Eastern
time) on the Exchange by dividing the total market value of the  Municipal  Bond
Fund's portfolio  investments and other assets  attributable to that class, less
any liabilities,  by the number of total  outstanding  shares of that class. Net
asset value will not be determined on days on which the Exchange is closed.

         Portfolio  securities and other assets for which market  quotations are
readily available are stated at market value.  Market value is determined on the
basis of last reported sales prices, or if no sales are reported, as is the case
for most securities traded over-the-counter,  at the mean between representative
bid and asked  quotations  obtained  from a quotation  reporting  system or from
established  market  makers.  Fixed  income  securities,  including  those to be
purchased  under firm commitment  agreements  (other than  obligations  having a
maturity of 60 days or less),  are  normally  valued on the basis of  quotations
obtained from brokers and dealers or pricing  services,  which take into account
appropriate  factors such as  institutional-sized  trading in similar  groups of
securities,  yield,  quality,  coupon  rate,  maturity,  type of issue,  trading
characteristics, and other market data.

         Short-term  investments having a maturity of 60 days or less are valued
at amortized cost, when the Board of Trustees  determines that amortized cost is
their fair  value.  Certain  fixed  income  securities  for which  daily  market
quotations  are not readily  available  may be valued,  pursuant  to  guidelines
established by the Board of Trustees,  with reference to fixed income securities
whose prices are more readily  obtainable and whose  durations are comparable to
the  securities  being valued.  Subject to the foregoing,  other  securities for
which market  quotations  are not readily  available are valued at fair value as
determined in good faith by the Board of Trustees.

         The Municipal Bond Fund's  liabilities are allocated among its classes.
The  total  of  such  liabilities   allocated  to  a  class  plus  that  class's
distribution and/or servicing fees and any other expenses specially allocated to
that class are then  deducted  from the  class's  proportionate  interest in the
Municipal Bond Fund's assets, and the resulting amount for each class is divided
by the number of shares of that class  outstanding  to produce the class's  "net
asset value" per share. Generally, for the Municipal Bond Fund, income dividends
are  expected  to differ  over time by  approximately  the amount of the expense
accrual differential between the Municipal Bond Fund's classes.
<PAGE>

DISTRIBUTIONS

         The Municipal Bond Fund pays out as dividends  substantially all of its
net investment income (which comes from dividends and interest it receives or is
deemed to receive  from its  investments)  and net realized  short-term  capital
gains. For these purposes and for federal income tax purposes,  a portion of the
premiums from certain  expired call or put options written by the Municipal Bond
Fund, net gains from closing purchase and sale transactions with respect to such
options,  and net gains from  futures  transactions  are  treated as  short-term
capital gains. The Municipal Bond Fund distributes  substantially all of its net
realized  capital gains,  if any,  after giving effect to any available  capital
loss carry-over.

         Shares begin earning dividends on the day after the date that funds are
received by the Trust for the purchase of shares.  For the Municipal  Bond Fund,
dividends  are declared  daily from net  investment  income to  shareholders  of
record  at  the  close  of  the  previous   business  day,  and  distributed  to
shareholders  monthly. Any net realized capital gains from the sale of portfolio
securities will be distributed no less frequently than once yearly. Dividend and
capital gain  distributions  of the  Municipal  Bond Fund will be  reinvested in
additional  shares of the Municipal Bond Fund unless the  shareholder  elects to
have them paid in cash. There are no sales charges on reinvested dividends. If a
shareholder has elected to receive  dividends and/or capital gain  distributions
in cash and the postal or other delivery  service is unable to deliver checks to
the  shareholder's  address of record,  such  shareholder's  distributions  will
automatically  be invested in the Money  Market Fund until such  shareholder  is
located.  Dividends from net investment income with respect to Class B and Class
C shares are expected to be lower than those paid with respect to Class A shares
as a result of the distribution fees applicable to Class B and C shares.

         Shareholders may elect to invest dividends and/or distributions paid by
the  Municipal  Bond Fund in shares of the same  class of any other  Fund of the
Trust at net asset value.  The shareholder  must have an account existing in the
Fund selected for investment with the identical  registered name and address and
must elect this option on the account  application,  on a form provided for that
purpose or by a telephone  request to the Transfer  Agent at  800-426-0107.  For
further information on this option,  contact your broker or call the Distributor
at 800-426-0107.

TAXES

         The  Municipal  Bond Fund intends to qualify as a regulated  investment
company  annually and to elect to be treated as a regulated  investment  company
under the Code. As such,  the Municipal Bond Fund generally will not pay federal
income tax on the income and gains it pays as dividends to its shareholders.  In
order to avoid a 4% federal  excise  tax,  the  Municipal  Bond Fund  intends to
distribute each year substantially all of its net income and gains.

         Shareholders  subject to U.S. federal income tax will be subject to tax
on any taxable  distributions  received from the Municipal Bond Fund, regardless
of whether  received in cash or reinvested in additional  shares.  Distributions
received by  tax-exempt  shareholders  generally  will not be subject to federal
income tax to the extent  permitted under  applicable tax law. All  shareholders
must treat  dividends,  other than  capital gain  dividends  or  dividends  that
represent a return of capital to shareholders, as ordinary income.

         Dividends  designated  by the  Municipal  Bond  Fund  as  capital  gain
dividends  derived from the Municipal Bond Fund's net capital gain (that is, the
excess  of  net  long-term  gain  over  net  short-term  loss)  are  taxable  to
shareholders  as long-term  capital gain except as provided by an applicable tax
exemption.  Under the Taxpayer Relief Act of 1997,  long-term capital gains will
generally be taxed at a 28% or 20% rate,  depending  upon the holding  period of
the portfolio securities. Any distributions that are not from the Municipal Bond
Fund's net investment  income,  short-term capital gain, or net capital gain may
be  characterized  as a return of capital to shareholders  or, in some cases, as
capital gain. Certain dividends  declared in October,  November or December of a
calendar year are taxable to shareholders  (who are subject to tax on dividends)
as though  received on December 31 of that year if paid to  shareholders  during
January of the following calendar year. For state income tax purposes,  interest
on some  federal  obligations  generally  is not exempt from  taxation,  whether
received  directly  by a  shareholder  or through  distributions  of  investment
company  taxable income (for example,  interest on FNMA and GNMA  Certificates).
The  Municipal  Bond Fund will  advise  shareholders  annually of the amount and
nature of the dividends paid to them.

         Dividends  paid to  shareholders  by the Municipal  Bond Fund which are
derived from  interest on Municipal  Bonds are expected to be  designated by the
Fund as "exempt-interest dividends," and shareholders generally may exclude such
dividends  from gross  income for federal  income tax  purposes.  However,  if a
shareholder  receives  social  security or  railroad  retirement  benefits,  the
shareholder may be taxed on a portion of those benefits as a result of receiving
tax-exempt  income.  In addition,  certain  exempt-interest  dividends could, as
discussed below, cause certain shareholders to become subject to the alternative
minimum  tax  and  may  increase  the  alternative   minimum  tax  liability  of
shareholders already subject to this tax.
<PAGE>

         To the extent that dividends paid to shareholders by the Municipal Bond
Fund are derived from taxable  interest or from capital  gains,  such  dividends
will be subject to federal  income tax.  Any gain  realized on a  redemption  of
shares will be taxable gain,  subject to any  applicable tax exemption for which
an investor may qualify.

         Dividends derived from interest on certain U.S.  Government  securities
may be exempt from state and local taxes,  although interest on  mortgage-backed
U.S.  Government  securities is generally not so exempt.  The  distributions  of
"exempt-interest  dividends"  paid by the Municipal Bond Fund may be exempt from
state and local  taxation when received by a shareholder to the extent that they
are derived from  interest on  Municipal  Bonds issued by the state or political
subdivision  in which  such  shareholder  resides.  The  federal  exemption  for
"exempt-interest dividends" attributable to Municipal Bonds does not necessarily
result in exemption of such  dividends  from income for the purpose of state and
local taxes. The Trust will report annually on a state-by-state basis the source
of income the Municipal Bond Fund receives on Municipal  Bonds that was paid out
as dividends during the preceding year.

         The Code also  provides  that  exempt-interest  dividends  allocable to
interest  received from "private activity bonds" issued after August 7, 1986 are
an item of tax preference for individual and corporate  alternative  minimum tax
at the applicable  rate for  individuals  and  corporations.  Therefore,  if the
Municipal  Bond Fund  invests in such  private  activity  bonds,  certain of its
shareholders  may become subject to the alternative  minimum tax on that part of
its  distributions  to them that are derived from interest income on such bonds,
and  certain  shareholders  already  subject  to  such  tax may  have  increased
liability therefor. However, it is the present policy of the Municipal Bond Fund
to invest no more than 20% of its assets in such bonds.  Other provisions of the
Code affect the tax treatment of distributions  from the Municipal Bond Fund for
corporations,  casualty  insurance  companies,  and financial  institutions.  In
particular, under the Code, for corporations, alternative minimum taxable income
will be  increased  by a  percentage  of the  amount by which the  corporation's
"adjusted  current earnings" (which includes various items of tax exempt income)
exceeds  the amount  otherwise  determined  to be  alternative  minimum  taxable
income.  Accordingly,  an  investment  in the  Municipal  Bond  Fund  may  cause
shareholders  to be subject to (or result in an increased  liability  under) the
alternative minimum tax.

         Dividends to shareholders of the Municipal Bond Fund derived from money
market  instruments  and U.S.  Government  securities  are generally  taxable as
ordinary income. The Fund may seek to reduce fluctuations in its net asset value
by engaging in portfolio  strategies  involving  options on securities,  futures
contracts,  and options on futures contracts.  Any gain derived by the Fund from
the use of such instruments, including by reason of "marking to market," will be
treated as a combination  of short-term  and long-term  capital gain and, if not
offset by realized  capital losses  incurred by the Fund, will be distributed to
shareholders  (possibly requiring the liquidation of other portfolio securities)
and will be taxable to  shareholders  as a  combination  of ordinary  income and
long-term capital gain.

         Interest  accrued  by the  Municipal  Bond Fund from  inflation-indexed
bonds will be includable in the Municipal Bond Fund's gross income in the period
in which they accrue.  Periodic adjustments for inflation in the principal value
of these  securities  also may give  rise to  original  issue  discount,  which,
likewise,  will be  includable  in the  Municipal  Bond Fund's gross income on a
current  basis,  regardless of whether the Municipal Bond Fund receives any cash
payments.  See  "Taxation--Original  Issue Discount" in the Trust's Statement of
Additional  Information.  Amounts  includable in the Municipal Bond Fund's gross
income become subject to tax-related distribution requirements. Accordingly, the
Municipal Bond Fund may be required to make annual distributions to shareholders
in excess of the cash  received in a given period from these  investments.  As a
result, the Municipal Bond Fund may be required to liquidate certain investments
at a time when it is not  advantageous  to do so. If the  principal  value of an
inflation-indexed  bond is  adjusted  downward  in any  period  as a  result  of
deflation,  the  reduction  may be treated as a loss to the extent the reduction
exceeds  coupon  payments  received  in that  period;  in that case,  the amount
distributable by the Municipal Bond Fund may be reduced and amounts  distributed
previously in the taxable year may be characterized  in some  circumstances as a
return of capital.
<PAGE>

         Taxable  shareholders  should note that the timing of their  investment
could  have  undesirable  tax  consequences.  If  shares  are  purchased  on  or
immediately before the record date of a dividend,  taxable shareholders will pay
full price for the shares and may receive a portion of their  investment back as
a taxable distribution.

         The  preceding  discussion  relates  only to federal  income  tax;  the
consequences  under  other  tax  laws may  differ.  For  additional  information
relating to the tax aspects of investing  in the  Municipal  Bond Fund,  see the
Trust's Statement of Additional Information.

         Fund Administrator

         Pacific  Investment  Management  also serves as  administrator  for the
Municipal  Bond  Fund's  Class  A,  Class B and  Class C shares  pursuant  to an
administration  agreement with the Trust. Pacific Investment Management provides
administrative  services  for Class A, Class B and Class C  shareholders  of the
Municipal Bond Fund,  which include  clerical help and accounting,  bookkeeping,
internal audit  services,  and certain other services  required by the Municipal
Bond Fund,  preparation of reports to the Municipal Bond Fund's shareholders and
regulatory filings. Pacific Investment Management may also retain certain of its
affiliates to provide certain of these services. In addition, Pacific Investment
Management,  at its own  expense,  arranges for the  provision of legal,  audit,
custody, transfer agency (including sub-transfer agency and other administrative
services) and other services for the Municipal Bond Fund, and is responsible for
the costs of registration of the Trust's shares and the printing of prospectuses
and  shareholder  reports for current  shareholders.

         The  Trust's  Funds  (and  not  Pacific   Investment   Management)  are
responsible for the following  expenses:  (i) salaries and other compensation of
any of the  Trust's  executive  officers  and  employees  who are not  officers,
directors,  stockholders  or employees of Pacific  Investment  Management or its
subsidiaries or affiliates;  (ii) taxes and  governmental  fees; (iii) brokerage
fees and commissions and other portfolio transaction expenses; (iv) the costs of
borrowing  money,  including  interest  expenses;  (v) fees and  expenses of the
Trustees who are not "interested  persons" of Pacific  Investment  Management or
the  Trust,  and any  counsel  retained  exclusively  for  their  benefit;  (vi)
extraordinary  expenses,  including  costs  of  litigation  and  indemnification
expenses; (vii) expenses, such as organizational expenses, which are capitalized
in accordance  with generally  accepted  accounting  principles;  and (viii) any
expenses  allocated or allocable to a specific  class of shares,  which  include
distribution  and  servicing  fees  payable with respect to Class A, Class B and
Class C shares,  and may include  certain  other  expenses as  permitted  by the
Trust's  Multi-Class  Plan  adopted  pursuant  to Rule 18f-3 under the 1940 Act,
subject to review and approval by the Trustees.

         Advisory and Administrative Fees

         The Municipal Bond Fund features fixed advisory and  administrative fee
rates.  For providing  investment  advisory and  administrative  services to the
Municipal Bond Fund as described above,  Pacific Investment  Management receives
monthly fees from the  Municipal  Bond Fund at an annual rate of (i) 0.25% based
on the average  daily net assets of the Municipal  Bond Fund for advisory  fees,
and (ii) 0.35%  attributable in the aggregate to the Municipal Bond Fund's Class
A, Class B and Class C shares for administrative fees.

         Both the investment advisory contract and administration agreement with
respect to Class A, Class B and Class C shares of the Municipal Bond Fund may be
terminated  by  the  Trustees  at any  time  on 60  days'  written  notice.  The
investment advisory contract may be terminated by Pacific Investment  Management
on 60 days'  written  notice.  Following the  expiration of the one-year  period
commencing with the  effectiveness of the  administration  agreement,  it may be
terminated  by  Pacific  Investment  Management  on  60  days'  written  notice.
Following its initial  two-year  term,  the  investment  advisory  contract will
continue  from year to year if approved by the  Trustees.  Following its initial
one-year term, the administration agreement with respect to Class A, Class B and
Class C shares of the Fund will  continue from  year-to-year  if approved by the
Trustees.
<PAGE>

         Portfolio Transactions

         Pursuant to the advisory contract, Pacific Investment Management places
orders for the purchase and sale of portfolio investments for the Municipal Bond
Fund's  accounts with brokers or dealers  selected by it in its  discretion.  In
effecting  purchases  and sales of portfolio  securities  for the account of the
Municipal Bond Fund, Pacific Investment  Management will seek the best price and
execution of the Municipal Bond Fund's  orders.  In doing so, the Municipal Bond
Fund may pay higher  commission  rates than the lowest  available  when  Pacific
Investment  Management  believes it is reasonable to do so in light of the value
of the  brokerage  and research  services  provided by the broker  effecting the
transaction.

         Pacific  Investment  Management manages the Municipal Bond Fund without
regard  generally  to  restrictions  on portfolio  turnover.  The use of certain
derivative  instruments  with relatively short maturities may tend to exaggerate
the portfolio turnover rate for the Municipal Bond Fund. Trading in fixed income
securities does not generally involve the payment of brokerage commissions,  but
does  involve  indirect  transaction  costs.  The use of futures  contracts  may
involve the payment of commissions to futures commission  merchants.  The higher
the rate of portfolio  turnover of the Municipal Bond Fund, the higher all these
transaction costs borne by the Municipal Bond Fund generally will be.

         Some  securities  considered for investments by the Municipal Bond Fund
may  also  be  appropriate  for  other  clients  served  by  Pacific  Investment
Management.  If a purchase or sale of securities  consistent with the investment
policies of the Municipal  Bond Fund and one or more of these clients  served by
Pacific  Investment  Management  is  considered  at  or  about  the  same  time,
transactions  in such securities will be allocated among the Municipal Bond Fund
and  clients  in a manner  deemed  fair and  reasonable  by  Pacific  Investment
Management. Pacific Investment Management may aggregate orders for the Municipal
Bond Fund with simultaneous transactions entered into on behalf of other clients
of Pacific Investment  Management so long as price and transaction  expenses are
averaged either for that transaction or for the day.

DESCRIPTION OF DURATION

         Duration is a measure of the expected  life of a fixed income  security
that was  developed  as a more  precise  alternative  to the concept of "term to
maturity." Traditionally,  a fixed income security's "term to maturity" has been
used as a proxy  for the  sensitivity  of the  security's  price to  changes  in
interest  rates  (which  is the  "interest  rate  risk" or  "volatility"  of the
security).  However,  "term to  maturity"  measures  only the time until a fixed
income security provides its final payment,  taking no account of the pattern of
the security's payments prior to maturity. In contrast,  duration incorporates a
bond's yield,  coupon interest  payments,  final maturity and call features into
one measure. Duration management is one of the fundamental tools used by Pacific
Investment Management.

         Duration is a measure of the expected  life of a fixed income  security
on a  present  value  basis.  Duration  takes the  length of the time  intervals
between the present time and the time that the interest and  principal  payments
are scheduled or, in the case of a callable bond,  expected to be received,  and
weights  them by the  present  values of the cash to be  received at each future
point in time. For any fixed income  security with interest  payments  occurring
prior to the payment of  principal,  duration is always less than  maturity.  In
general,  all other things  being equal,  the lower the stated or coupon rate of
interest of a fixed income  security,  the longer the duration of the  security;
conversely,  the higher the stated or coupon rate of interest of a fixed  income
security, the shorter the duration of the security.
<PAGE>

         Futures,  options  and  options on futures  have  durations  which,  in
general,  are closely  related to the duration of the securities  which underlie
them.  Holding  long  futures or call option  positions  (backed by a segregated
account  of cash and cash  equivalents)  will  lengthen  a  Fund's  duration  by
approximately  the  same  amount  that  holding  an  equivalent  amount  of  the
underlying securities would.

         Short futures or put option  positions have durations  roughly equal to
the negative duration of the securities that underlie these positions,  and have
the effect of reducing  portfolio duration by approximately the same amount that
selling an equivalent amount of the underlying securities would.

         There are some situations where even the standard duration  calculation
does not properly reflect the interest rate exposure of a security. For example,
floating and variable rate securities often have final maturities of ten or more
years; however, their interest rate exposure corresponds to the frequency of the
coupon reset. For  inflation-indexed  bonds, duration is calculated on the basis
of modified real duration,  which  measures  price changes of  inflation-indexed
bonds on the basis of changes in real,  rather  than  nominal,  interest  rates.
Another  example where the interest  rate  exposure is not properly  captured by
duration  is the case of  mortgage  pass-through  securities.  The stated  final
maturity of such securities is generally 30 years, but current  prepayment rates
are more  critical  in  determining  the  securities'  interest  rate  exposure.
Finally,  the duration of a fixed income security may vary over time in response
to  changes  in  interest  rates and other  market  factors.  In these and other
similar  situations,  Pacific Investment  Management will use more sophisticated
analytical  techniques  that  incorporate  the  anticipated  economic  life of a
security into the determination of its interest rate exposure.

DESCRIPTION OF SECURITIES RATINGS

         The Municipal Bond Fund makes use of average  portfolio  credit quality
standards to assist  institutional  investors  whose own  investment  guidelines
limit their  investments  accordingly.  In determining the Municipal Bond Fund's
overall  dollar-weighted  average quality,  unrated securities are treated as if
rated, based on Pacific Investment  Management's view of their  comparability to
rated  securities.  The Municipal Bond Fund's use of average quality criteria is
intended  to be a guide  for  those  institutional  investors  whose  investment
guidelines  require that assets be invested  according to  comparable  criteria.
Reference to an overall  average quality rating for the Municipal Bond Fund does
not mean that all securities  held by the Fund will be rated in that category or
higher.  The  Municipal  Bond  Fund's  investments  may  range in  quality  from
securities rated in the lowest category in which the Fund is permitted to invest
to securities  rated in the highest  category (as rated by Moody's or S&P or, if
unrated,  determined  by  Pacific  Investment  Management  to be  of  comparable
quality).  The  percentage  of the  Municipal  Bond  Fund's  assets  invested in
securities in a particular rating category will vary. Following is a description
of Moody's and S&P's ratings applicable to fixed income securities.

         Aaa:  Bonds  which are rated Aaa are judged to be of the best  quality.
They carry the smallest degree of investment risk and are generally  referred to
as  "gilt  edge."  Interest   payments  are  protected  by  a  large  or  by  an
exceptionally   stable  margin  and  principal  is  secure.  While  the  various
protective  elements are likely to change, such changes as can be visualized are
most unlikely to impair the fundamentally strong position of such issues.

         Aa:  Bonds  which are rated Aa are judged to be of high  quality by all
standards. Together with the Aaa group they comprise what are generally known as
high-grade  bonds.  They are rated lower than the best bonds because  margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present that
make the long-term risks appear somewhat larger than with Aaa securities.

         A: Bonds which are rated A possess many favorable investment attributes
and are to be  considered  as  upper-medium-grade  obligations.  Factors  giving
security to principal and interest are  considered  adequate but elements may be
present that suggest a susceptibility to impairment sometime in the future.

         Baa:  Bonds  which  are  rated  Baa  are  considered  as   medium-grade
obligations  (i.e.,  they are  neither  highly  protected  nor poorly  secured).
Interest  payments and principal  security  appear  adequate for the present but
certain  protective  elements  may  be  lacking  or  may  be  characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.

         Ba: Bonds which are rated Ba are judged to have  speculative  elements;
their future  cannot be  considered  as  well-assured.  Often the  protection of
interest  and  principal  payments  may be very  moderate  and  thereby not well
safeguarded  during  both good and bad times  over the  future.  Uncertainty  of
position characterizes bonds in this class.

         B:  Bonds  which  are  rated  B  generally  lack  characteristics  of a
desirable  investment.  Assurance  of  interest  and  principal  payments  or of
maintenance  of other terms of the contract  over any long period of time may be
small.

         Caa: Bonds which are rated Caa are of poor standing. Such issues may be
in default or there may be present  elements of danger with respect to principal
or interest.

         Ca:  Bonds  which  are  rated  Ca  represent   obligations   which  are
speculative  in a high  degree.  Such  issues are often in default or have other
marked shortcomings.

         C:  Bonds  which are rated C are the  lowest  rated  class of bonds and
issues so rated can be  regarded  as having  extremely  poor  prospects  of ever
attaining any real investment standing.

         Moody's applies numerical modifiers, 1, 2, and 3 in each generic rating
classified from Aa through B in its corporate bond rating system. The modifier 1
indicates  that the  security  ranks in the  higher  end of its  generic  rating
category;  the  modifier 2  indicates a mid-range  ranking;  and the  modifier 3
indicates that the issue ranks in the lower end of its generic rating category.

         Corporate Short-Term Debt Ratings

         Moody's  short-term debt ratings are opinions of the ability of issuers
to repay punctually  senior debt obligations which have an original maturity not
exceeding one year.  Obligations relying upon support mechanisms such as letters
of credit and bonds of indemnity are excluded unless explicitly rated.

         Moody's  employs the  following  three  designations,  all judged to be
investment grade, to indicate the relative repayment ability of rated issuers:

         PRIME-1:  Issuers rated  Prime-1 (or  supporting  institutions)  have a
superior ability for repayment of senior  short-term debt  obligations.  Prime-1
repayment   ability  will  often  be   evidenced   by  many  of  the   following
characteristics:  leading market positions in well-established  industries; high
rates of return on funds employed;  conservative  capitalization  structure with
moderate reliance on debt and ample asset protection;  broad margins in earnings
coverage of fixed  financial  charges and high  internal  cash  generation;  and
well-established  access to a range of financial  markets and assured sources of
alternate liquidity.

         PRIME-2:  Issuers rated  Prime-2 (or  supporting  institutions)  have a
strong ability for repayment of senior  short-term debt  obligations.  This will
normally be evidenced by many of the characteristics cited above but to a lesser
degree. Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics,  while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

         PRIME-3:  Issuers rated Prime-3 (or  supporting  institutions)  have an
acceptable ability for repayment of senior short-term obligations. The effect of
industry  characteristics  and  market  compositions  may  be  more  pronounced.
Variability in earnings and  profitability may result in changes in the level of
debt protection measurements and may require relatively high financial leverage.
Adequate alternate liquidity is maintained.

         NOT PRIME:  Issuers rated Not Prime do not fall within any of the Prime
rating categories.

Standard & Poor's Ratings Services

         Corporate and Municipal Bond Ratings

         Investment Grade

         AAA: Debt rated AAA has the highest rating assigned by S&P. Capacity to
pay interest and repay principal is extremely strong.
<PAGE>

         AA: Debt rated AA has a very strong  capacity to pay interest and repay
principal and differs from the highest rated issues only in small degree.

         A:  Debt  rated A has a  strong  capacity  to pay  interest  and  repay
principal  although it is somewhat more  susceptible  to the adverse  effects of
changes in  circumstances  and  economic  conditions  than debt in higher  rated
categories.

         BBB:  Debt rated BBB is regarded as having an adequate  capacity to pay
interest and repay principal.  Whereas it normally exhibits adequate  protection
parameters,  adverse economic  conditions,  or changing  circumstances  are more
likely to lead to a weakened  capacity to pay interest and repay  principal  for
debt in this category than in higher-rated categories.

         Speculative Grade

         Debt rated BB, B, CCC,  CC, and C is regarded  as having  predominantly
speculative  characteristics  with respect to capacity to pay interest and repay
principal. BB indicates the least degree of speculation and C the highest. While
such debt will likely have some quality and  protective  characteristics,  these
are outweighed by large uncertainties or major exposures to adverse conditions.

         BB:  Debt rated BB has less  near-term  vulnerability  to default  than
other  speculative  issues.  However,  it faces major ongoing  uncertainties  or
exposure to adverse business, financial, or economic conditions which could lead
to inadequate  capacity to meet timely interest and principal  payments.  The BB
rating  category  is also  used for debt  subordinated  to  senior  debt that is
assigned an actual or implied BBB- rating.

         B: Debt rated B has a greater  vulnerability  to default but  currently
has the capacity to meet  interest  payments and principal  repayments.  Adverse
business,  financial,  or economic  conditions  will likely  impair  capacity or
willingness to pay interest and repay  principal.  The B rating category is also
used for debt  subordinated to senior debt that is assigned an actual or implied
BB or BB- rating.

         CCC:  Debt  rated CCC has a  currently  identifiable  vulnerability  to
default and is  dependent  upon  favorable  business,  financial,  and  economic
conditions to meet timely payment of interest and repayment of principal. In the
event of adverse business, financial or economic conditions, it is not likely to
have the capacity to pay interest and repay  principal.  The CCC rating category
is also used for debt  subordinated to senior debt that is assigned an actual or
implied B or B- rating.

         CC: The rating CC is typically  applied to debt  subordinated to senior
debt that is assigned an actual or implied CCC rating.

         C: The rating C is  typically  applied to debt  subordinated  to senior
debt that is assigned an actual or implied CCC- debt rating. The C rating may be
used to cover a situation where a bankruptcy  petition has been filed,  but debt
service payments are continued.

         CI: The rating CI is reserved  for income bonds on which no interest is
being paid.
<PAGE>

         D: Debt rated D is in payment  default.  The D rating  category is used
when interest  payments or principal  payments are not made on the date due even
if the  applicable  grace period has not expired,  unless S&P believes that such
payments will be made during such grace  period.  The D rating will also be used
upon  the  filing  of  a  bankruptcy  petition  if  debt  service  payments  are
jeopardized.

         Plus (+) or Minus (-):  The  ratings  from AA to CCC may be modified by
the addition of a plus or minus sign to show relative  standing within the major
rating categories.

         Provisional  ratings:  The  letter  "p"  indicates  that the  rating is
provisional.  A  provisional  rating  assumes the  successful  completion of the
project  being  financed by the debt being rated and  indicates  that payment of
debt service  requirements is largely or entirely  dependent upon the successful
and timely  completion of the project.  This rating,  however,  while addressing
credit quality subsequent to completion of the project,  makes no comment on the
likelihood  of, or the risk of default  upon  failure of, such  completion.  The
investor  should  exercise his own judgment with respect to such  likelihood and
risk.

         r: The "r" is attached to  highlight  derivative,  hybrid,  and certain
other  obligations  that S&P believes may  experience  high  volatility  or high
variability  in  expected  returns  due to  non-credit  risks.  Examples of such
obligations  are:  securities  whose  principal or interest return is indexed to
equities,  commodities,  or currencies;  certain swaps and options; and interest
only and principal only mortgage securities.

         The absence of an "r" symbol should not be taken as an indication  that
an obligation will exhibit no volatility or variability in total return.

         N.R.: Not rated.

         Debt   obligations  of  issuers  outside  the  United  States  and  its
territories  are rated on the same basis as  domestic  corporate  and  municipal
issues. The ratings measure the  creditworthiness of the obligor but do not take
into account currency exchange and related uncertainties.

PIMCO Funds
Notes to Pro Forma Combined Financial Statement (unaudited)
March 31, 1998
- --------------------------------------------------------------------------------

Basis of Presentation:

Subject to the approval of the  Agreement and Plan of  Reorganization  ("Plan of
Reorganization")  by the  shareholders  of the Tax  Exempt  Fund (the  "Acquired
Fund"),  a series of PIMCO Funds:  Multi-Manager  Series ("MMS"),  the Municipal
Bond  Fund  (the  "Acquiring  Fund"),  a  series  of the  PIMCO  Funds:  Pacific
Investment Management Series ("PF") would acquire all the assets of the Acquired
Fund in exchange for newly issued shares of beneficial interest of the Acquiring
Fund (the "Merger  Shares") and the assumption by the respective  Acquiring Fund
of all of the liabilities of the Acquired Fund followed by a distribution of the
Merger Shares to the shareholders of the Acquired Fund.

As a result of the proposed transaction, the Acquired Fund will receive a number
of Class A, Class B and Class C shares of the  Acquiring  Fund equal in value to
the value of the net  assets of the  Acquired  Fund,  net of costs  incurred  to
effect the acquisition, being transferred and attributable to the Class A, Class
B and Class C shares of the Acquired Fund. Following the transfer, each Class A,
Class B and Class C share of the  Acquired  Fund  will  receive,  on a  tax-free
basis, a number of full and fractional Class A, Class B or Class C Merger Shares
of the Acquiring Fund equal in value,  as of the close of business on the day of
the  exchange,  to the value of the  shareholder's  Class A,  Class B or Class C
Acquired Fund shares.

The pro forma  combined  financial  statements  reflect the  combined  financial
position of the PF Municipal  Bond Fund with the MMS Tax Exempt Fund  (hereafter
the "Combined  Fund") at March 31, 1998, and the pro forma  combined  results of
operations  of the Combined  Fund for the period from April 1, 1997 to March 31,
1998, as though the reorganization had occurred on April 1, 1997.

The pro forma combined financial statements are presented for the information of
the  reader  and may not  necessarily  be  representative  of how the pro  forma
combined  financial  statements  would  have  appeared  had  the  reorganization
actually occurred. The pro forma combined financial statements should be read in
conjunction  with  the  historical   financial   statements  of  the  respective
portfolios.

Pro Forma Adjustments:

The pro  forma  combined  Statements  of  Assets  and  Liabilities  reflect  the
reclassification  of capital for the  Acquired  Fund into  shares of  beneficial
interest of the Acquiring Fund. Also, the paid in capital and total  liabilities
reflect an adjustment for $24,241 at March 31, 1998 for the MMS Tax Exempt Fund,
relating  to the  estimated  non-recurring  costs to effect  the  reorganization
including such items as legal, accounting, registration and proxy costs.

The  pro  forma  combined   Statements  of  Operations   reflect  the  following
adjustments:

         A decrease  in the  advisory  fee paid by the MMS Tax Exempt Fund as a
         result of the  application of the .25% advisory fee of the PF Municipal
         Bond Fund.  Previously,  the advisory  fees paid by the  Acquired  Fund
         included certain  administrative  services which will be included under
         an administrative  fee paid by the retail  shareholders of the combined
         Funds as described below.

         The  administration  fee paid by the Class A, B and C shareholders  of
         MMS Tax Exempt Fund was decreased as a result of the application of the
         .35%  administration fee applicable to the corresponding  share classes
         of the PF Municipal Bond Fund.

         The 12b-1 fee paid by the Class C shareholders  of the MMS Tax Exempt
         Fund  has  been  decreased  by .25% to  reflect  the  voluntary  waiver
         undertaken by the Distributor.

                                OTHER INFORMATION


Item 15. Indemnification

                  Reference   is  made  to  Article   IV  of  the   Registrant's
                  Declaration  of Trust,  which was filed with the  Registrant's
                  initial Registration Statement.

                  Insofar as indemnification  for liabilities  arising under the
                  Securities Act of 1933 may be permitted to trustees,  officers
                  and  controlling  persons of the  Registrant by the Registrant
                  pursuant  to  the  Declaration  of  Trust  or  otherwise,  the
                  Registrant is aware that in the opinion of the  Securities and
                  Exchange  Commission,  such  indemnification is against public
                  policy   as   expressed   in  the  Act  and,   therefore,   is
                  unenforceable.  In the event that a claim for  indemnification
                  against  such  liabilities  (other  than  the  payment  by the
                  Registrant of expenses incurred or paid by trustees,  officers
                  or controlling  persons of the  Registrant in connection  with
                  the  successful  defense of any act,  suit or  proceeding)  is
                  asserted by such trustees,  officers or controlling persons in
                  connection  with the shares being  registered,  the Registrant
                  will, unless in the opinion of its counsel the matter has been
                  settled  by  controlling  precedent,  submit  to  a  court  of
                  appropriate    jurisdiction    the   question   whether   such
                  indemnification by it is against public policy as expressed in
                  the Act and will be governed by the final adjudication of such
                  issues.

Item 17. Undertakings

                   (1) The  undersigned  registrant  agrees  that  prior  to any
                  public reoffering of the securities registered through the use
                  of a prospectus which is a part of this registration statement
                  by any  person or party  who is  deemed  to be an  underwriter
                  within the  meaning of Rule 145(c) of the  Securities  Act [17
                  CFR  230.145c],  the  reoffering  prospectus  will contain the
                  information called for by the applicable registration form for
                  reofferings  by  persons  who may be deemed  underwriters,  in
                  addition to the  information  called for by the other items of
                  the applicable form.

                   (2) The undersigned  registrant  agrees that every prospectus
                  that is filed  under  paragraph  (1) above  will be filed as a
                  part of an amendment to the  registration  statement  and will
                  not be used until the  amendment is  effective,  and that,  in
                  determining   any   liability   under  the  1933   Act,   each
                  post-effective   amendment   shall  be  deemed  to  be  a  new
                  registration statement for the securities offered therein, and
                  the offering of the securities at that time shall be deemed to
                  be the initial bona fide offering of them.

                  post-effective  amendment,  an opinion of counsel or a copy of
