                               PROXY STATEMENT OF

                          THIRD AVENUE HIGH YIELD FUND

                        PROSPECTUS FOR CLASS A SHARES OF

                             PIONEER HIGH YIELD FUND

     This proxy  statement and prospectus  contains the  information  you should
know before voting on the proposed reorganization of your fund into Pioneer High
Yield Fund. Please read it carefully and retain it for future reference.

HOW THE REORGANIZATION WILL WORK:

o    Your fund will  transfer  all of its  assets to Pioneer  High  Yield  Fund.
     Pioneer  High Yield  Fund will  assume  your  fund's  liabilities  that are
     included  in the  calculation  of your fund's net assets at the closing and
     liabilities with respect to your fund's investment  operations that are not
     required by generally accepted accounting  principles to be included in the
     calculation  of net asset value.

o    Pioneer High Yield Fund will issue Class A shares to your fund in an amount
     equal to the value of your fund's  shares.  Class A shares of Pioneer  High
     Yield Fund having a value on the reorganization  date equal to the value of
     your shares of your fund will be distributed in exchange for your shares of
     your fund.

o    The  reorganization  is  intended  to be tax free for  federal  income  tax
     purposes.

o    Your  fund  will be  liquidated  and  terminated,  and you  will  become  a
     shareholder of Pioneer High Yield Fund.

WHY YOUR FUND'S TRUSTEES ARE RECOMMENDING THE REORGANIZATION:

     The trustees of your fund believe that  reorganizing your fund into Pioneer
High Yield Fund is in the best interest of your fund. In August 1999, the fund's
portfolio manager became a dual employee of Pioneer Investment Management,  Inc.
(Pioneer) and your fund's  adviser,  EQSF  Advisers,  Inc. She also has informed
Pioneer  that she will become an employee  solely of Pioneer  whether or not the
reorganization  occurs.  Among other things, the reorganization will provide the
shareholders of your fund with continuity of management, and it is also expected
to result in a lower  overall  expense  ratio,  after giving effect to voluntary
expense  limitations.  Therefore,  the  trustees  recommend  you  vote  FOR  the
reorganization.

REORGANIZATION

o    The  reorganization  is  scheduled  to occur after the close of business on
     February  25,  2000,  but may occur as of any later date on or before April
     15, 2000 or  otherwise  agreed to by the funds.  Upon  consummation  of the
     reorganization,  your fund will  transfer all of its assets to Pioneer High
     Yield Fund in exchange for shares of Pioneer High Yield Fund.  Pioneer High
     Yield Fund will also assume your fund's  liabilities  that are  included in
     the  calculation  of your fund's net assets at the closing and  liabilities
     with respect to your fund's investment  operations that are not required by
     generally accepted accounting  principles to be included in the calculation
     of net asset value.  The net asset values of both funds will be computed as
     of the close of the New York Stock  Exchange  (normally  4:00 p.m.  Eastern
     time) on the reorganization date.

o    Pioneer  High  Yield Fund will issue to your fund Class A shares of Pioneer
     High Yield Fund in an amount equal to the aggregate net asset value of your
     fund's shares.  Class A shares of Pioneer High Yield Fund having a value on
     the reorganization date equal to the value of your shares of your fund will
     be distributed to you in exchange for shares of your fund. As a result, all
     shareholders  of your fund will become Class A shareholders of Pioneer High
     Yield Fund.

o    After the  reorganization  is complete,  your fund will be  liquidated  and
     terminated.

o    The  reorganization  is  intended  to be tax free for  federal  income  tax
     purposes.

     At all asset levels, the annual management fee rate payable by Pioneer High
Yield Fund (without giving effect to expense limitations) is lower than the rate
paid by  your  fund.  Pioneer  High  Yield  Fund  also  has  breakpoints  in its
management  fee which may reduce the  effective  management  fee rate as Pioneer
High Yield  Fund's  assets  grow.  While you may benefit from Pioneer High Yield
Fund's reduced  management fee, you will pay Rule 12b-1 fees as a shareholder of
Pioneer  High  Yield  Fund.  Depending  upon the size of the fund,  this fee may
offset  some or all of the  benefit  of the  lower  management  fee or result in
higher overall expenses.

     The expenses of Class A shares of Pioneer High Yield Fund include an annual
Rule 12b-1 fee equal to 0.25% of average daily net assets  attributable to Class
A shares.  In calculating the Rule 12b-1 fee payable by Pioneer High Yield Fund,
Pioneer  will  not  include  the  assets  held in  accounts  established  in the
reorganization  (other than assets held in an omnibus  account  with a financial
intermediary).  However, since Rule 12b-1 fees are not assessed at a shareholder
account level,  the effect will be a reduction in the Rule 12b-1 fee paid by all
Class A  shareholders  and not a waiver of the Rule  12b-1 fee for  shareholders
participating in the reorganization.  Because  approximately 51% (as of November
30,  1999) of your fund's  assets are held in omnibus  accounts  with  financial
intermediaries,  this exclusion  will not materially  reduce the amount of 12b-1
fees  incurred.  YOU  SHOULD  UNDERSTAND  THAT  IF  YOU  VOTE  IN  FAVOR  OF THE
REORGANIZATION,  YOU ARE  APPROVING  A  REORGANIZATION  INTO A CLASS  OF  SHARES
SUBJECT TO RULE 12B-1 DISTRIBUTION FEES.

     The  advisers  to both  funds  currently  waive all or a  portion  of their
management  fees or  reimburse  the  respective  funds  to  limit  total  annual
operating  expenses.  Your fund  currently  limits  expenses to 1.90% of average
daily net assets on the first $100 million and 1.50% of average daily net assets
in excess of $100 million.  Pioneer High Yield Fund currently limits expenses to
0.75% on Class A shares of the fund. Consequently, as long as Pioneer High Yield
Fund's expense limitation remains in effect,  Pioneer High Yield Fund's expenses
will be substantially  lower than the historic expenses of your fund.  Pioneer's
fee waiver and expense reimbursement  agreement is voluntarily and temporary and
may be revised or  terminated  at any time.  SINCE  PIONEER IS NOT  OBLIGATED TO
MAINTAIN THE EXPENSE  LIMITATION,  YOU SHOULD CONSIDER THE POTENTIAL EFFECT THAT
THE REORGANIZATION  WILL HAVE ON PER SHARE EXPENSES WITHOUT GIVING EFFECT TO THE
EXPENSE LIMITATION.

     Pioneer High Yield Fund  anticipates  that its Class A share  expense ratio
will be 1.50% for the fiscal year ending  October 31, 2000 (0.75%  after  giving
effect to the expense  limitation).  This ratio is lower than your fund's  gross
expense ratio of 3.99% (1.90% after giving effect to the expense limitation) for
the period ended October 31, 1998.



                               RISK/RETURN SUMMARY

INVESTMENT OBJECTIVES

     THIRD  AVENUE  HIGH  YIELD  FUND.  To  maximize   total  return  through  a
combination of income and capital appreciation.

     PIONEER HIGH YIELD FUND.  Maximize  total return  through a combination  of
income and capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

     THIRD AVENUE HIGH YIELD FUND. Third Avenue High Yield Fund invests at least
65% of its total  assets  in bonds  and  preferred  stocks  of  companies  whose
securities are rated below investment grade (and comparable unrated  securities)
at the time of the fund's  investment.  Securities  are rated  below  investment
grade if they are rated below Baa3 by Moody's Investors Service,  Inc. and below
BBB- by Standard & Poor's Ratings Group.  Such securities are commonly  referred
to as "junk bonds." The fund will acquire  securities of companies whose capital
structures,  in the opinion of the  adviser,  have a market  value  priced below
their takeover  values.  The fund will also invest in bonds and preferred stocks
that are convertible into the equity of the issuer.  Convertible securities have
general  characteristics  similar to both fixed income and equity securities and
provide the  possibility of capital  appreciation  should the underlying  common
stock increase in value. The fund can invest in securities with any maturity the
fund's adviser believes is appropriate.

     PIONEER  HIGH YIELD FUND.  Normally,  the fund  invests at least 65% of its
total assets (at the time of purchase)  in below  investment  grade (high yield)
debt securities and preferred  stocks. A debt security is below investment grade
if it is rated BB or lower by Standard & Poor's  Ratings Group or the equivalent
rating by a nationally recognized securities rating organization or, if unrated,
determined  to be of  equivalent  credit  quality by  Pioneer.  These high yield
securities may be  convertible  into the equity  securities of the issuer.  Debt
securities rated below investment grade are commonly referred to as "junk bonds"
and are considered  speculative.  Below investment grade debt securities involve
greater  risk of loss,  are  subject to greater  price  volatility  and are less
liquid, especially during periods of economic uncertainty or change, than higher
rated debt securities.


                                       5
<PAGE>


     The fund's  investments  may have all types of interest  rate and  dividend
payment and reset terms,  including  fixed rate,  adjustable  rate, zero coupon,
contingent,  deferred,  payment  in kind and  auction  rate  features.  The fund
invests in securities with a broad range of maturities.

INVESTMENT PHILOSOPHY

     The investment  philosophy of both funds is  substantially  the same,  with
both advisers applying a value approach to investing.

     THIRD AVENUE HIGH YIELD FUND. EQSF Advisers, Inc. adheres to a strict value
discipline in selecting  securities.  This means seeking securities whose prices
are low in  relation  to what the  adviser  believes  is the  true  value of the
securities.   The  adviser   believes   this  both  lowers  risk  and  increases
appreciation  potential.  The fund intends its investments in debt securities to
be, for the most part,  in  securities  which the adviser  believes will provide
above-average current yields, yields to events, or yields to maturity.  The fund
identifies  investment  opportunities  through intensive  research of individual
companies and ignores  general stock market  conditions and other macro factors.
For these reasons,  the fund may seek investments in the securities of companies
or industries that are temporarily depressed.  The fund follows a "buy and hold"
strategy.  The fund will generally sell an investment only when there has been a
fundamental  change in the business or capital  structure  of the company  which
significantly affects the investment's inherent value.

     PIONEER HIGH YIELD FUND.  Pioneer,  the fund's investment  adviser,  uses a
value approach to select the fund's  investments.  Using this investment  style,
Pioneer seeks securities  selling at reasonable prices or substantial  discounts
to their underlying values and then holds these securities for their incremental
yields or until the  market  values  reflect  their  intrinsic  values.  Pioneer
evaluates  a  security's  potential  value  based on the  company's  assets  and
prospects for earnings growth.  In making that  assessment,  Pioneer employs due
diligence  and  fundamental  research,  an evaluation of the issuer based on its
financial  statements  and  operations.  Pioneer  also  considers  a  security's
potential to provide income. In assessing the appropriate  maturity,  rating and
sector weighting of the fund's portfolio, Pioneer considers a variety of factors
that are expected to influence  economic  activity  and  interest  rates.  These
factors include fundamental economic  indicators,  such as the rates of economic
growth and inflation,  Federal Reserve monetary policy and the relative value of
the U.S.  dollar  compared  to  other  currencies.  In  making  these  portfolio
decisions,  Pioneer relies on the knowledge,  experience and judgment of its own
staff who have access to a wide variety of research.

PRINCIPAL RISKS OF INVESTING IN THE FUNDS

     Each fund is subject  to  similar  risks.  Even  though  each fund seeks to
maximize  total return,  you could lose money on your  investment or not make as
much as if you invested elsewhere if:

o    Interest  rates go up,  causing the value of debt  securities in the fund's
     portfolio to decline

o    The issuer of a security  owned by the fund  defaults on its  obligation to
     pay principal and/or interest or has its credit rating downgraded

o    During  periods  of  declining  interest  rates,  the  issuer of a security
     exercises its option to prepay  principal  earlier than scheduled,  forcing
     the fund to reinvest in lower yielding securities. This is known as call or
     prepayment risk

o    During periods of rising interest rates,  the average life of certain types
     of  securities  is  extended  because  of slower  than  expected  principal
     payments.  This may lock in a below  market  interest  rate,  increase  the
     security's duration and reduce the value of the security.  This is known as
     extension risk

o    The  adviser's  judgment  about  the  attractiveness,   relative  value  or
     potential  appreciation  of a  particular  sector,  security or  investment
     strategy proves to be incorrect

o    A downturn in equity markets causes the price of convertible  securities to
     drop even when the prices of below  investment  grade bonds otherwise would
     not go down

     INVESTMENT  IN HIGH YIELD  SECURITIES  INVOLVES  SUBSTANTIAL  RISK OF LOSS.
These securities are considered speculative with respect to the issuer's ability
to pay  interest  and  principal  and are  susceptible  to default or decline in
market  value due to adverse  economic  and  business  developments.  The market
values for high yield securities tend to be very volatile,  and these securities
are less liquid than investment grade debt securities.  For these reasons,  your
investment in either fund is subject to the following specific risks:

o    Increased price  sensitivity to changing  interest rates and  deteriorating
     economic environment

o    Greater risk of loss due to default or declining credit quality

o    Adverse company specific events are more likely to render the issuer unable
     to make interest and/or principal payments

o    A negative  perception of the high yield market  develops,  depressing  the
     price and  liquidity of high yield  securities.  This  negative  perception
     could last for a significant period of time


                                       6

     Each  fund is not  diversified,  which  means  that it can  invest a higher
percentage  of its  assets in any one  issuer  than a  diversified  fund.  Being
non-diversified  may magnify the fund's losses from adverse  events  affecting a
particular issuer.

EACH FUND'S PAST PERFORMANCE

     Performance  information  for  Pioneer  High  Yield  Fund is not  presented
because  the  fund  has  not  yet  commenced   operations.   Annual  performance
information  for Third Avenue High Yield Fund is not presented  because the fund
has not been in operation for a full calendar year. Fund performance varies from
year to year. A fund's past  performance  does not  necessarily  indicate how it
will perform in the future. As a shareholder, you may lose or make money on your
investment.

FEES AND EXPENSES

     Shareholders  of both  funds  pay  various  expenses,  either  directly  or
indirectly.  The following  expense table for Third Avenue High Yield Fund shows
fund  expenses  for the year ended  October 31,  1998.  Future  expenses  may be
greater or less.

     expense reimbursement arrangement will terminate after the reorganization).
     The fund will repay EQSF Advisers, Inc. the amount of its reimbursement for
     up to three years following the  reimbursement  to the extent fund expenses
     drop below 1.9%. EQSF Advisers,  Inc.  expects to continue to reimburse the
     fund for these expenses for the foreseeable future. Either the fund or EQSF
     Advisers, Inc. can terminate this arrangement at any time.

OTHER INVESTMENT STRATEGIES

     As discussed,  each fund invests  primarily in below  investment grade debt
securities and preferred stocks to maximize total return.

     This  section  describes  additional  investments  that a fund  may make or
strategies  that it may pursue to a lesser  degree to achieve  the fund's  goal.
Some of the funds'  secondary  investment  policies also entail risks.  To learn
more about these investments and risks, you should obtain and read the statement
of additional information (SAI).

CONVERTIBLE SECURITIES

     Each fund may invest in bonds and  preferred  stocks  that are  convertible
into the equity securities of the issuer. Convertible securities generally offer
lower  interest or dividend  yields than  non-convertible  securities of similar
quality.  As with all fixed income securities,  the market values of convertible
securities  tend to decline as  interest  rates  increase  and,  conversely,  to
increase as interest rates decline. However, when the market price of the common
stock  underlying a  convertible  security  exceeds the  conversion  price,  the
convertible  security tends to reflect the market price of the underlying common
stock.  As the  market  price  of the  underlying  common  stock  declines,  the
convertible  security tends to trade  increasingly on a yield basis and thus may
not  decline  in  price to the  same  extent  as the  underlying  common  stock.
Convertible  securities  rank  senior to common  stocks in an  issuer's  capital
structure and consequently entail less risk than the issuer's common stock.

EQUITY SECURITIES

     Consistent  with its objective  each fund may invest in equity  securities,
including common stocks, depositary receipts,  warrants, rights and other equity
interests.  Equity securities represent an ownership interest in an issuer, rank
junior in a company's  capital structure to debt securities and consequently may
entail greater risk of loss than fixed income securities.

MORTGAGE-BACKED AND ASSET-BACKED SECURITIES

     Each  fund may  invest  in  mortgage-backed  and  asset-backed  securities.
Mortgage-backed  securities may be issued by private companies or by agencies of
the U.S.  government and represent direct or indirect  participation  in, or are
collateralized  by and payable from,  mortgage  loans secured by real  property.
Asset-backed  securities  represent  participations  in, or are  secured  by and
payable from, assets such as installment sales or loan contracts, leases, credit
card receivables and other categories of receivables.

FOREIGN SECURITIES

     Third  Avenue High Yield Fund does not limit the  percentage  of its assets
that may be invested in non-U.S.  issuers, but only invests in non-U.S.  issuers
meeting certain disclosure standards.


                                       8
<PAGE>


     Pioneer High Yield Fund may invest in securities of Canadian issuers to the
same extent as securities of U.S. issuers.  The fund may invest up to 15% of its
total  assets (at the time of  purchase)  in  securities  of  non-U.S.  issuers,
including debt and equity securities of corporate issuers and debt securities of
government issuers in developed and emerging markets.  Investing in Canadian and
non-U.S. issuers may involve unique risks compared to investing in securities of
U.S. issuers.  These risks are more pronounced to the extent the fund invests in
issuers in emerging markets or concentrates  such investments in any one region.
These risks may include:

o    Less information about non-U.S.  issuers or markets may be available due to
     less rigorous disclosure and accounting standards or regulatory practices

o    Many  non-U.S.  markets are smaller,  less liquid and more  volatile.  In a
     changing  market,  Pioneer  might not be able to sell the fund's  portfolio
     securities in amounts and at prices it considers reasonable

o    Adverse  effect of currency  exchange rates or controls on the value of the
     fund's investments

o    Political,  economic  and social  developments  that  adversely  affect the
     securities markets

o    Withholding and other non-U.S. taxes may decrease the fund's return

TEMPORARY INVESTMENTS

     Normally,  Pioneer High Yield Fund invests  substantially all of its assets
to meet its  investment  objective.  Pioneer  High  Yield  Fund may  invest  the
remainder of its assets in securities with remaining maturities of less than one
year,  cash  equivalents  or may hold cash.  For temporary  defensive  purposes,
Pioneer High Yield Fund may depart from its principal investment  strategies and
invest  part or all of its  assets in these  securities.  During  such  periods,
Pioneer  High Yield Fund may not be able to achieve  its  investment  objective.
Similarly,  your fund may hold all or a portion of its assets in short-term U.S.
government  obligations,  cash or cash  equivalents  when  the  adviser  deems a
short-term  defensive  posture  appropriate.  Pioneer High Yield Fund intends to
adopt a defensive strategy only when Pioneer believes high yield securities have
extraordinary risks due to political or economic factors.

SHORT-TERM TRADING

     The funds usually do not trade for short-term profits.  Each fund will sell
an investment, however, even if it has only been held for a short time, if it no
longer meets the fund's investment criteria. If a fund does a lot of trading, it
may incur  additional  operating  expenses,  which would reduce  performance and
could cause  shareholders to receive larger  distributions  of taxable income or
capital gains.

DERIVATIVES

     Pioneer High Yield Fund may use futures,  options, forward foreign currency
exchange  contracts  and other  derivatives.  Your fund has  expressed no policy
regarding  these  instruments.  A derivative is a security or  instrument  whose
value is  determined  by reference to the value or the change in value of one or
more securities,  currencies,  indices or other financial  instruments.  Pioneer
High Yield Fund does not use derivatives as a primary  investment  technique and
generally limits their use to hedging.  However, Pioneer High Yield Fund may use
derivatives for a variety of purposes, including:

o    As a hedge against adverse  changes in stock market prices,  interest rates
     and currency exchange rates

o    As a substitute for purchasing or selling securities

o    To  increase  the  fund's  return  as a  non-hedging  strategy  that may be
     considered speculative

     Even a small  investment in derivatives can have a significant  impact on a
fund's  exposure to stock market  values,  interest  rates or currency  exchange
rates.  If changes in a  derivative's  value do not correspond to changes in the
value of the fund's other  investments,  the fund may not fully  benefit from or
could lose money on the  derivative  position.  In  addition,  some  derivatives
involve  risk of loss if the person who issued the  derivative  defaults  on its
obligation.  Certain  derivatives  may be less  liquid  and  more  difficult  to
value.

YEAR 2000

     Information  technology  experts are  concerned  about  computer  and other
electronic  systems'  ability to process  date-related  information on and after
January 1, 2000. This scenario, commonly referred to as the "Year 2000 problem,"
could have an adverse impact on the funds and the provision of services to their
shareholders.  Each fund has  addressed  and  continues to monitor the Year 2000
problem  with  respect  to its  systems  and those used by its  distributor  and
transfer  agent.  Each  fund has  obtained  assurances  from its  other  service
providers that they are taking  appropriate  Year 2000 measures and each fund is
monitoring their efforts. Although neither fund expects the Year 2000 problem to
adversely  impact it, neither fund can guarantee that its, or the fund's service
providers', efforts will be successful.

                          PROPOSAL TO APPROVE AGREEMENT
                           AND PLAN OF REORGANIZATION

REORGANIZATION

o    The  reorganization  is  scheduled  to occur after the close of business on
     February 25, 2000 but may occur as of any later date on or before April 15,
     2000  or  otherwise  agreed  to by  the  funds.  Upon  consummation  of the
     reorganization,  your fund will  transfer all of its assets to Pioneer High
     Yield Fund in exchange for shares of Pioneer High Yield Fund.  Pioneer High
     Yield Fund will also assume your fund's  liabilities  that are  included in
     the  calculation  of your fund's net assets at the closing and  liabilities
     with respect to your fund's investment  operations that are not required by
     generally accepted accounting  principles to be included in the calculation
     of net asset value.  The net asset values of both funds will be computed as
     of the close of the New York Stock  Exchange  (normally  4:00 p.m.  Eastern
     time) on the reorganization date.

o    Pioneer  High  Yield Fund will issue to your fund Class A shares of Pioneer
     High Yield Fund in an amount equal to the aggregate net asset value of your
     fund's shares.  Class A shares of Pioneer High Yield Fund having a value on
     the reorganization date equal to the value of your shares of your fund will
     be distributed to you in exchange for shares of your fund. As a result, all
     shareholders  of your fund will become Class A shareholders of Pioneer High
     Yield Fund.

o    After the  reorganization  is complete,  your fund will be  liquidated  and
     terminated.

o    The  reorganization  is  intended  to be tax free for  federal  income  tax
     purposes.

DESCRIPTION OF REORGANIZATION

     The  shareholders  of your fund are being asked to approve an Agreement and
Plan of Reorganization,  a copy of which is attached as Exhibit A. The Agreement
provides for a reorganization on the terms described above.

REASONS FOR THE PROPOSED REORGANIZATION

     The  board  of  trustees   of  your  fund   believes   that  the   proposed
reorganization will be advantageous to the shareholders of your fund for several
reasons.  The board of trustees considered the following matters,  among others,
in approving the proposal.

     FIRST,  shareholders  of your fund  would  enjoy  continuity  of  portfolio
management.  Margaret  D.  Patel,  the  portfolio  manager  of your  fund  since
inception,  will be the portfolio  manager for Pioneer High Yield Fund.  She has
informed  your fund  that she  intends  to manage  Pioneer  High  Yield  Fund in
substantially the same manner in which she manages your fund.

     SECOND,  it is expected that Pioneer High Yield Fund's actual expenses will
be  lower  than  your  fund's  actual  expenses.  This is  because  Pioneer  has
temporarily  agreed to limit the  expenses of Class A shares to 0.75% of average
daily net assets,  while your fund  currently  has an expense  limit of 1.90% of
average  daily net assets on the first $100  million and 1.50% of average  daily
net assets in excess of $100 million.  Consequently,  shareholders  of your fund
are expected to pay  significantly  lower expenses each month as shareholders of
Pioneer High Yield Fund than they would if the reorganization did not occur, for
at least as long as the voluntary expense limitations on the funds' expenses are
continued.  Since Pioneer is not  obligated to maintain the expense  limitation,
you should consider the potential  effect that the  reorganization  will have on
per share expenses without giving effect to the expense limitation.

     Furthermore,  there is the  potential  that Pioneer High Yield Fund's total
annual  operating  expenses  will  continue  to be lower  than the total  annual
operating  expenses of your fund even after  termination of the expense  waiver.
Although the combined Rule 12b-1 and management fees for Pioneer High Yield Fund
are greater than the  management  fee for your fund so long as the net assets of
Pioneer High Yield Fund are $500 million or less, they are equal to or less than
your fund's management fee at net asset levels in excess of $500 million.  There
can be no  assurance  if or when  Pioneer  High Yield Fund would have  assets in
excess of $500  million.  This  difference  could  more than  offset  the higher
combined Rule 12b-1 and management  fees of Pioneer High Yield Fund at net asset
levels below $500 million.

     THIRD,  Pioneer High Yield Fund shares received in the reorganization  will
provide  your  fund's   shareholders  with  substantially  the  same  investment
advantages as they currently have.

     FOURTH, Pioneer offers a diverse family of mutual funds, with over 20 funds
that will be available to your fund's shareholders through exchanges.  Your fund
is  exchangeable  for  shares  of the  other  three  Third  Avenue  funds and an
unaffiliated separately managed money market fund.

     FIFTH,  EQSF  Advisers,  Inc. does not expect to retain the services of Ms.
Patel after the reorganization  (or, in the event that the reorganization is not
expected  to  occur,  such  earlier  date as  determined  by Ms.  Patel  or EQSF
Advisers,  Inc.) and does not have  other  portfolio  managers  with  comparable
experience in managing high yield portfolios, nor does it expect to hire another
portfolio  manager with such expertise.  Consequently,  EQSF Advisers,  Inc. has
advised your fund that if the  reorganization  is not  completed,  EQSF Advises,
Inc.  expects to recommend to your fund's trustees that your fund be liquidated.
Your fund's trustees could accept or reject such a recommendation.


                                       10
<PAGE>


A  liquidation  would  be  taxable  to  your fund's  shareholders  and would not
offer the  potential  advantages  of the  reorganization.  In  recommending  the
transaction,  your fund's board considered the fact that the  reorganization  is
expected to be able to be completed on a tax-free basis.

     The board of  trustees  of  Pioneer  High Yield  Fund  considered  that the
reorganization  presents an  opportunity  for Pioneer High Yield Fund to acquire
investment assets without the obligation to pay commissions or other transaction
costs that are normally associated with the purchase of securities. The trustees
also  believe  that your  fund's  shareholders  and  Pioneer  High Yield  Fund's
shareholders will benefit from the resulting continuity of management, including
the intended use of your fund's  performance record as Pioneer High Yield Fund's
own.  The  ability of  Pioneer  High Yield  Fund to  utilize  your  fund's  past
performance  may be effective in drawing new  shareholders to Pioneer High Yield
Fund.  This  could  have the  effect of  increasing  the  fund's  asset base and
lowering overall expenses for shareholders.

     The board of trustees of Pioneer High Yield Fund also  considered  that the
advisers to both funds will benefit  from the  reorganization.  Because  Pioneer
High Yield Fund will have a performance  record,  Pioneer  expects to be able to
increase the size of the fund at a faster rate than would otherwise be possible.
Such an increase in size benefits  Pioneer by  accelerating  the period at which
management of the fund is profitable.  EQSF Advisers, Inc. will benefit from the
reorganization  because  Pioneer  has agreed to make  certain  payments  to EQSF
Advisers,  Inc. if the reorganization is completed.  EQSF Advisers, Inc. will be
entitled  to be paid by Pioneer  $250,000  plus an annual fee equal to 0.549% of
the average  daily net assets of Pioneer  High Yield Fund during the first three
years after the reorganization.

     COMPARATIVE FEES AND EXPENSE RATIOS. As discussed above, Pioneer High Yield
Fund pays a  management  fee rate lower  than your  fund's fee rate at all asset
levels. Pioneer High Yield Fund also has breakpoints in its management fee which
may reduce the effective management fee rate as Pioneer High Yield Fund's assets
grow.  While you may benefit from Pioneer High Yield Fund's  reduced  management
fee, you will pay Rule 12b-1 fees as a  shareholder  of Pioneer High Yield Fund.
Depending  upon the size of the  fund,  this fee may  offset  some or all of the
benefit of the lower management fee or result in higher overall expenses.

     In addition  to a lower  management  fee rate,  Pioneer  High Yield  Fund's
estimated Class A expense ratio of 1.50% is lower than your fund's gross expense
ratio of 3.99% (0.75% vs. 1.90%, respectively, for net expenses with the expense
limitations).

     The expenses of Class A shares of Pioneer High Yield Fund include an annual
Rule 12b-1 fee equal to 0.25% of average daily net assets  attributable to Class
A shares.  In calculating the Rule 12b-1 fee payable by Pioneer High Yield Fund,
Pioneer  will  not  include  the  assets  held in  accounts  established  in the
reorganization,  except for omnibus accounts  maintained by a broker,  financial
intermediary or recordkeeper. However, since Rule 12b-1 fees are not assessed at
a shareholder  account  level,  the effect will be a reduction in the Rule 12b-1
fee paid by all Class A shareholders  and not a waiver of the Rule 12b-1 fee for
shareholders participating in the reorganization.

     Your  trustees do not  believe,  given your fund's  current size and growth
rate,  that in the near  future your fund will grow to an asset size which would
allow your fund to realize the  benefits of economies  of scale.  Your  trustees
also do not  believe  that in the near future your fund will reach an asset size
that will allow your fund to significantly  increase the  diversification of its
investment portfolio.  In addition, the adviser to your fund may not continue to
subsidize a portion of your fund's expenses indefinitely. If the adviser were to
discontinue this voluntary expense  limitation,  your fund's expense ratio would
rise even higher above  Pioneer  High Yield  Fund's Class A expense  ratio after
giving effect to Pioneer's fee waiver.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The  reorganization  is intended to be tax free for United  States  federal
income tax purposes.  The consummation of the  reorganization  is conditioned on
the receipt by both funds of an opinion as of the closing  from  Skadden,  Arps,
Slate,  Meagher & Flom  (Illinois),  counsel to Third  Avenue  High Yield  Fund,
substantially  to the effect that,  on the basis of facts,  representations  and
assumptions set forth in the opinion,  the  reorganization  will be treated as a
"reorganization"  within the meaning of Section  368(a) of the Internal  Revenue
Code of 1986,  as amended  (the  "Code"),  and Pioneer High Yield Fund and Third
Avenue  High Yield Fund will each be a party to such  reorganization  within the
meaning  of  Section  368(b) of the Code.  Accordingly,  no gain or loss will be
recognized  by  Pioneer  High Yield  Fund or Third  Avenue  High Yield Fund as a
result  of the  reorganization,  and no  gain or loss  will be  recognized  by a
shareholder  of Third  Avenue High Yield Fund who receives  solely  Pioneer High
Yield Fund shares in exchange for shares of Third Avenue High Yield Fund.

     The  aggregate  tax  basis of the  Pioneer  High  Yield  Fund  shares to be
received by shareholders of Third Avenue High Yield Fund will be the same as the
aggregate tax basis in the shares of Third Avenue High Yield Fund surrendered in
exchange therefor,  and the holding period of the Pioneer High Yield Fund shares
to be received by  shareholders  of Third  Avenue High Yield Fund in  connection
with the  reorganization  will include the holding period of the shares of Third
Avenue High Yield Fund  surrendered  in  exchange  therefor,  provided  that the
shares  in Third  Avenue  High  Yield  Fund are held as a  capital  asset at the
closing of the reorganization.

     No tax  ruling  has  been or will be  received  from the  Internal  Revenue
Service ("IRS") in connection with the reorganization.  An opinion of counsel is
not binding on the IRS or a court,  and no  assurance  can be given that the IRS
would not assert, or a court would not sustain, a contrary position.

     THE ABOVE  DISCUSSION MAY NOT APPLY TO PARTICULAR  CATEGORIES OF HOLDERS OF
SHARES OF THIRD  AVENUE HIGH YIELD FUND SUBJECT TO SPECIAL  TREATMENT  UNDER THE
CODE, SUCH AS FOREIGN HOLDERS OR HOLDERS WHOSE SHARES WERE ACQUIRED  PURSUANT TO
THE  EXERCISE  OF  AN  EMPLOYEE  STOCK  OPTION  OR  OTHERWISE  AS  COMPENSATION.
SHAREHOLDERS  OF THIRD  AVENUE  HIGH YIELD  FUND ARE URGED TO CONSULT  THEIR TAX
ADVISERS TO DETERMINE THE SPECIFIC TAX  CONSEQUENCES  OF THE  REORGANIZATION  TO
THEM,   INCLUDING   ANY  STATE,   LOCAL  OR  OTHER  TAX   CONSEQUENCES   OF  THE
REORGANIZATION.

ADDITIONAL TERMS OF AGREEMENT AND PLAN OF REORGANIZATION

     SURRENDER OF SHARE CERTIFICATES. Shareholders of your fund whose shares are
represented  by  one  or  more  share  certificates  need  not  surrender  their
certificates.  After the reorganization,  certificates  evidencing  ownership of
your fund's  shares will  evidence  ownership  of Pioneer High Yield Fund shares
received in the reorganization.  Shareholders must continue to follow procedures
for surrendering  your fund's share  certificates (or delivering the appropriate
affidavit)  in order to redeem  shares of  Pioneer  High  Yield  Fund  after the
reorganization. Pioneer High Yield Fund will not issue share certificates in the
reorganization.

     CONDITIONS TO CLOSING THE  REORGANIZATION.  The  obligation of your fund to
consummate  the  reorganization  is  subject  to  the  satisfaction  of  certain
conditions,  including  the  performance  by Pioneer  High Yield Fund of all its
obligations  under the Agreement and Plan of  Reorganization  and the receipt of
all consents, orders and permits necessary to consummate the reorganization (see
Sections 7 and 9 of Exhibit A).

     The obligation of Pioneer High Yield Fund to consummate the  reorganization
is subject to the  satisfaction  of certain  conditions,  including  your fund's
performance  of  all  of  its  obligations  under  the  Agreement  and  Plan  of
Reorganization,  the receipt of certain documents and financial  statements from
your fund and the  receipt of all  consents,  orders and  permits  necessary  to
consummate the reorganization (see Sections 8 and 9 of Exhibit A).

     The  obligations of both funds are subject to the approval of the Agreement
and Plan of  Reorganization  by the necessary vote of the outstanding  shares of
your fund, in accordance with the provisions of your fund's trust instrument and
by-laws.

     TERMINATION OF AGREEMENT AND PLAN OF REORGANIZATION. The boards of trustees
of your fund and Pioneer  High Yield Fund may agree to terminate  the  Agreement
and Plan of  Reorganization  even if the  shareholders of your fund have already
approved it, at any time before the  reorganization  date, if the boards believe
that proceeding with the reorganization would no longer be advisable.

     EXPENSES OF THE REORGANIZATION.  Pioneer will pay for all expenses incurred
in connection with the reorganization except that (i) your fund will pay for all
expenses incurred in connection with its liquidation and termination and (ii) if
the shareholders of your fund do not approve the reorganization,  EQSF Advisers,
Inc. will pay 50% of expenses incurred in connection with the reorganization, up
to $20,000, and Pioneer will pay the remainder.


                                 CAPITALIZATION

     The following  table sets forth the PRO FORMA  combined  capitalization  of
both funds as if the  reorganization  had occurred on April 30, 1999.  The table
reflects PRO FORMA  exchange  ratios of  approximately  one Class A Pioneer High
Yield Fund share being issued for each share of your fund.  Because Pioneer High
Yield  Fund  will  consist  only of the  Class A  shares  obtained  through  the
reorganization,  the exchange  ratio will most likely  remain 1:1 on the closing
date.

     It is  impossible  to predict how many Class A shares of Pioneer High Yield
Fund  will   actually  be  received  and   distributed   by  your  fund  on  the

or value of Pioneer  High Yield Fund shares that will  actually be received  and

                      BOARDS' EVALUATION AND RECOMMENDATION

     For the  reasons  described  above,  the board of  trustees  of your  fund,
including  the  trustees  who are not  "interested  persons" of your fund or the
adviser (the independent trustees), approved the reorganization.  In particular,
the trustees determined that the reorganization was in the best interest of your
fund. Similarly, the board of trustees of Pioneer High Yield Fund, including the
independent trustees, approved the reorganization. They also determined that the
reorganization  was in the best  interest  of Pioneer  High Yield  Fund.  If the
reorganization  is not approved,  your trustees will consider what other actions
may be appropriate, including the possible liquidation of your fund.

     THE  TRUSTEES  OF YOUR FUND  RECOMMEND  THAT YOU VOTE FOR THE  PROPOSAL  TO
APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION.


                                       12

                         VOTING RIGHTS AND REQUIRED VOTE

     Each  share of your fund is  entitled  to one vote.  Approval  of the above
proposal  requires the affirmative vote of a majority of the shares of your fund
outstanding and entitled to vote.

     Shares of your fund  represented  in person or by proxy,  including  shares
which abstain or do not vote with respect to the  proposal,  will be counted for
purposes of determining  whether there is a quorum at the meeting.  Accordingly,
an abstention from voting has the same effect as a vote AGAINST the proposal.

     If a broker or nominee  holding  shares in "street  name"  indicates on the
proxy  card  that  it  does  not  have  discretionary  authority  to vote on the
proposal,  those shares will NOT be  considered  present and entitled to vote on
the  proposal.  Thus, a "broker  non-vote" has the same effect as a vote AGAINST
the proposal because shares represented by a "broker non-vote" are considered to
be outstanding shares.

     If the required  approval of shareholders  is not obtained,  your fund will
continue  to engage  in  business  as a  separate  mutual  fund and the board of
trustees  will consider what further  action may be  appropriate,  including the
possible liquidation of your fund.


                     ADDITIONAL INFORMATION ABOUT THE FUNDS

NET ASSET VALUE

     Each fund's net asset  value is the value of its  portfolio  of  securities
plus any other assets minus its  operating  expenses and any other  liabilities.
Each fund  calculates a net asset value every day the New York Stock Exchange is
open when regular trading closes (normally 4:00 p.m. Eastern time).

     Each fund generally values its portfolio  securities based on market prices
or  quotations.  When market prices are not  available or are  considered by the
adviser to be unreliable,  the fund may use an asset's fair value. Fair value is
determined  in  accordance  with  procedures  approved  by the fund's  trustees.
International  securities  markets may be open on days when the U.S. markets are
closed. For this reason, the values of any international securities owned by the
fund could change on a day when you cannot buy or sell shares of the fund.

     You buy or sell shares at the net asset value per share  calculated  on the
day of your transaction.

PIONEER HIGH YIELD FUND. FOR  INFORMATION  ABOUT BUYING,  EXCHANGING AND SELLING

GENERAL RULES ON BUYING, EXCHANGING AND SELLING YOUR PIONEER HIGH YIELD FUND
SHARES

SHARE PRICE

     If you place an order with your  investment  firm before the New York Stock
Exchange  closes and your  investment  firm submits the order to the distributor
prior to the  distributor's  close of business (usually 5:30 p.m. Eastern time),
your share price will be calculated  that day.  Otherwise,  your price per share
will be  calculated  at the  close  of the New York  Stock  Exchange  after  the
distributor  receives  your  order.  Your  investment  firm is  responsible  for
submitting your order to the distributor.

BUYING

     You may buy Pioneer  High Yield Fund shares from any  investment  firm that
has a sales  agreement  with the  distributor.  If you do not have an investment
firm, please call  1-800-225-6292 for information on how to locate an investment
professional in your area.

     You can buy Pioneer High Yield Fund shares at the offering  price,  the net
asset  value per share plus the  applicable  sales  charge.  Shareholders  whose
Pioneer  High  Yield  Fund  accounts  were   established  as  a  result  of  the
reorganization   may  purchase   additional  shares  at  net  asset  value.  The
distributor may reject any order until it has confirmed the order in writing and
received  payment.  The fund  reserves  the right to stop  offering any class of
shares.

MINIMUM INVESTMENT AMOUNTS

     Your  initial  investment  in  Class  A  shares  must be at  least  $1,000.
Additional investments must be at least $100 for Class A shares. You may qualify
for  lower  initial  or  subsequent  investment  minimums  if you are  opening a
retirement plan account,  establishing  an automatic  investment plan or placing
your trade through your investment firm. The minimum initial  investment  amount
does not apply for purposes of the reorganization.

EXCHANGING

     You may  exchange  your shares  only for Class A shares of another  Pioneer
mutual fund.

     Your exchange request must be for at least $1,000.

SELLING

     Your shares will be sold at net asset value per share next calculated after
Pioneer High Yield Fund receives your request in good order.

     The fund  generally  will send your sale  proceeds  by check,  bank wire or
electronic funds transfer. Normally you will be paid within seven days.

     If you are selling  shares from a  non-retirement  account or certain IRAs,
you may use any of the methods described below. If you are selling shares from a
retirement account other than an IRA, you must make your request in writing.

     You may have to pay federal income taxes on a sale or an exchange.

FINANCIAL INTERMEDIARIES

     If you  invest  in the  fund  through  investment  professionals  or  other
financial  intermediaries,   including  wrap  programs  and  fund  supermarkets,
additional  conditions  may  apply  to  your  investment  in the  fund,  and the
investment  professional or intermediary may charge you a  transaction-based  or
other fee for its services.  These  conditions and fees are in addition to those
imposed  by the  fund  and  its  affiliates.  You  should  ask  your  investment
professional  or financial  intermediary  about its services and any  applicable
fees.

GOOD ORDER MEANS THAT:

o    You have provided adequate instructions
o    There are no outstanding claims against your account
o    There are no transaction limitations on your account
o    If you have any  fund  share  certificates,  you  submit  them and they are
     signed by each record owner exactly as the shares are registered
o    Your request includes a signature guarantee if you:
     -- Are selling over $100,000 or exchanging over $500,000 worth
        of shares
     -- Changed your account registration or address within the last 30 days
     -- Instruct the transfer agent to mail the check to an address different
        from the one on your account
     -- Want the check paid to someone other than the account owner(s)
     -- Are transferring the sale proceeds to a Pioneer mutual fund account with

                  funds are available in the amount of your
                  investment.

PIONEER HIGH YIELD FUND SHAREHOLDER ACCOUNT POLICIES

SIGNATURE GUARANTEES AND OTHER REQUIREMENTS

     You are required to obtain a signature guarantee when you are:

o    Requesting certain types of exchanges or sales of fund shares

o    Redeeming shares for which you hold a share certificate

o    Requesting certain types of changes for your existing account

     You can  obtain a  signature  guarantee  from most  broker-dealers,  banks,
credit  unions (if  authorized  under  state law) and  federal  savings and loan
associations. You cannot obtain a signature guarantee from a notary public.

     Fiduciaries and corporations are required to submit additional documents to
sell fund shares.

EXCHANGE LIMITATION

     You may  make up to four  exchanges  of  $25,000  or more per  account  per
calendar  year out of the  fund.  Except as  noted,  you may make any  number of
exchanges of less than $25,000.  The fund's  exchange  limitation is intended to
discourage  short-term  trading in fund shares.  Short-term trading can increase
the expenses incurred by the fund and make portfolio  management less efficient.
In determining whether the exchange  redemption limit has been reached,  Pioneer
may aggregate a series of exchanges  (each valued at less than  $25,000)  and/or
fund accounts that appear to be under common  ownership or control.  Pioneer may
view  accounts for which one person gives  instructions  or accounts that act on
advice provided by a single source to be under common control.

     The exchange  limitation does not apply to automatic exchange  transactions
or to exchanges made by  participants  in  employer-sponsored  retirement  plans
qualified  under Section 401 of the Code. The exchange  limitation  also may not
apply to transactions made through an omnibus account for fund shares.

MINIMUM ACCOUNT SIZE

     The fund requires that you maintain a minimum account value of $500. If you
hold less than the minimum in your  account  because you have sold or  exchanged
some of your shares,  the fund will notify you of its intent to sell your shares
and close  your  account.  You may avoid  this by  increasing  the value of your
account to at least the minimum within six months of the notice from the fund.

TELEPHONE ACCESS

     You may have  difficulty  contacting the fund by telephone  during times of
market volatility or disruption in telephone service. If you are unable to reach
the fund by telephone, you should communicate with the fund in writing.

SHARE CERTIFICATES

     Normally,  your shares will remain on deposit with the  transfer  agent and
certificates  will  not be  issued.  If you are  legally  required  to  obtain a
certificate,  you may  request  one for your Class A shares  only.  A fee may be
charged for this service.

FORMER THIRD AVENUE HIGH YIELD FUND SHAREHOLDERS

     You may purchase  shares in any Pioneer mutual fund,  either directly or by
exchange,  for any account established as a result of the reorganization without
a sales  charge.  These  shares will not be subject to the Class A  distribution
fee,  except that Class A shares  held in an omnibus  account are subject to the
Class A distribution fee whether those shares were issued in connection with the
reorganization or were later purchased by direct investment or by exchange.

OTHER POLICIES

     The fund may suspend  transactions  in shares when  trading on the New York
Stock Exchange is closed or restricted,  when an emergency  exists that makes it
impracticable for the fund to sell or value its portfolio securities or with the
permission of the Securities and Exchange Commission.

     The fund or the  distributor  may revise,  suspend or terminate the account
options and services available to shareholders at any time.

     The fund  reserves  the  right to redeem  in kind by  delivering  portfolio
securities  to  a  redeeming  shareholder,  provided  that  the  fund  must  pay
redemptions in cash if a shareholder's  aggregate redemptions in a 90-day period
are less than $250,000 or 1% of the fund's net assets.

DIVIDENDS AND CAPITAL GAINS

     Pioneer High Yield Fund declares a dividend from any net investment  income
and any short-term  capital gains each business day. You begin earning dividends
on the first business day following  receipt of payment for shares;  your shares
continue  to earn  dividends  up to and  including  the  date you  redeem  them.
Dividends  are  normally  paid on the last  business day of the month or shortly
thereafter.  Pioneer High Yield Fund distributes net long-term capital gains, if
any,  in  November.   Pioneer  High  Yield  Fund  may  also  pay  dividends  and
distributions  at other times if necessary for the fund to avoid federal  income
or excise tax. If you invest in the fund close to the time that the fund makes a
capital gain  distribution,  generally you will pay a higher price per share and
you will pay taxes on the amount of the capital  gain  distribution  whether you
reinvest the distribution or receive it as cash.

     Sales and exchanges may be taxable transactions to shareholders.

TAXES

     For federal  income tax  purposes,  distributions  from  Pioneer High Yield
Fund's net long-term  capital gains are considered  long-term  capital gains and
may be taxable to you at different maximum rates depending upon their source and
other factors.  Dividends and short-term  capital gain distributions are taxable
as ordinary income.  Dividends and distributions  are taxable,  whether you take
payment in cash or reinvest  them to buy  additional  fund shares.  You may also
have tax  consequences  (generally,  a  capital  gain or loss)  when you sell or
exchange fund shares. Each year the fund will mail to you information about your
dividends  and  distributions  for,  and the shares  you sold in,  the  previous
calendar year.

     You  must  provide   your  social   security   number  or  other   taxpayer
identification number to the fund along with the certifications  required by the
IRS  when  you  open an  account.  If you do not or if it is  otherwise  legally
required to do so, the fund will withhold 31% "backup withholding" tax from your
dividends and distributions, sale proceeds and any other payments to you.

     You  should  ask  your own tax  adviser  about  any  federal  or state  tax
considerations,  including  possible  additional  withholding taxes for non-U.S.
shareholders.   You  may  also  consult  the  fund's   statement  of  additional
information for a more detailed  discussion of federal income tax considerations
that may affect the fund and its shareholders.


                  MATERIAL PROVISIONS OF MANAGEMENT AGREEMENTS

THIRD AVENUE HIGH YIELD FUND

     Your fund entered into a management  agreement with EQSF Advisers,  Inc. on
February 9, 1998 (the "existing  agreement").  After its initial  two-year term,
the existing  agreement would continue from year to year if approved annually by
the fund's board of trustees.  The existing  agreement  may be terminated at any
time  without  penalty  upon 60 days'  written  notice by either  party and will
automatically terminate upon assignment thereof.

     Pursuant to the  existing  agreement,  your fund pays the adviser a monthly
fee equal to 0.90%  annually of your fund's  average daily net assets,  based on
the prior  month's net assets.  During the fiscal year ended  October 31,  1998,
your fund paid management fees to EQSF Advisers, Inc. equal to $50,472.

     Under current arrangements,  whenever in any fiscal year your fund's normal
operating  expenses,  including  the  investment  advisory  fee,  but  excluding
brokerage  commissions  and  interest  and taxes,  exceed 1.9% of the first $100
million of average daily net assets of the fund, and 1.5% of assets in excess of
$100  million,  EQSF  Advisers,  Inc. is obligated  to reimburse  the fund in an
amount  equal to that  excess.  If  operating  expenses  fall below that expense
limitation,  the fund will begin  repaying  EQSF  Advisers,  Inc. for the amount
contributed on behalf of the fund.  This repayment will continue for up to three
years after the end of the fiscal year in which an expense is  reimbursed by the
adviser, subject to the expense limitation,  until the adviser has been paid for
the entire amount  contributed or such  three-year  period expires (this expense
reimbursement arrangement will terminate after the reorganization).

     Under the existing agreement, EQSF Advisers, Inc. supervises and assists in
the  management  of  your  fund,   provides  investment  research  and  research
evaluation and makes and executes  recommendations  for the purchase and sale of
securities.  EQSF Advisers,  Inc.  furnishes at its expense all necessary office
equipment and personnel  necessary for  performance of its  obligations and pays
the compensation for executive duties of officers of the fund.

     All  other  expenses  incurred  in the  operation  of  your  fund  and  the
continuous  offering  of its  shares,  including  taxes,  fees and  commissions,
bookkeeping expenses, fund employees,  expenses of redemption of shares, charges
of administrators,  custodians and transfer agents,  auditing and legal expenses
and fees of outside trustees are borne by the fund.

PIONEER HIGH YIELD FUND

     Pioneer  High  Yield  Fund  has  contracted  with  Pioneer  to  act  as its
investment  adviser.  Pioneer is a wholly owned subsidiary of The Pioneer Group,
Inc. (PGI).  PGI is engaged in the financial  services  business in the U.S. and
other  countries.  Certain  trustees or officers of Pioneer  High Yield Fund are
also  directors  and/or  officers of PGI and its  subsidiaries  (see  management
biographies below).

     As Pioneer High Yield Fund's investment adviser,  Pioneer provides the fund
with  investment  research,  advice and  supervision and furnishes an investment
program  for the  fund  consistent  with the  fund's  investment  objective  and
policies,  subject to the supervision of the fund's trustees. Pioneer determines
what portfolio securities will be purchased or sold, arranges for the placing of
orders for the  purchase or sale of  portfolio  securities,  selects  brokers or
dealers to place those orders,  maintains  books and records with respect to the
fund's  securities  transactions,  and  reports  to the  trustees  on the fund's
investments and performance.

     Under the terms of its contract with Pioneer High Yield Fund,  Pioneer pays
all the  operating  expenses,  including  executive  salaries  and the rental of
office space,  relating to its services for the fund,  with the exception of the
following,  which  are paid by the  fund:  (a)  charges  and  expenses  for fund
accounting,  pricing and appraisal services and related overhead,  including, to
the  extent  such  services  are  performed  by  personnel  of  Pioneer,  or its
affiliates, office space and facilities and personnel compensation, training and
benefits; (b) the charges and expenses of auditors; (c) the charges and expenses
of any custodian,  transfer agent,  plan agent,  dividend  disbursing  agent and
registrar  appointed by the fund; (d) issue and transfer taxes chargeable to the
fund in connection  with  securities  transactions to which the fund is a party;
(e) insurance premiums,  interest charges, dues and fees for membership in trade
associations  and all taxes and  corporate  fees payable by the fund to federal,
state  or  other  governmental  agencies;  (f) fees  and  expenses  involved  in
registering and maintaining registrations of the fund and/or its shares with the
Securities and Exchange  Commission,  state or blue sky securities  agencies and
foreign jurisdictions,  including the preparation of prospectuses and statements
of additional  information  for filing with such  regulatory  agencies;  (g) all
expenses of shareholders' and trustees' meetings and of preparing,  printing and
distributing  prospectuses,   notices,  proxy  statements  and  all  reports  to
shareholders  and to  governmental  agencies;  (h) charges and expenses of legal
counsel to the fund and the trustees;  (i) distribution fees paid by the fund in
accordance with Rule 12b-1 promulgated by the Securities and Exchange Commission
pursuant to the Investment  Company Act of 1940 (1940 Act); (j)  compensation of
those trustees of the fund who are not affiliated with or interested  persons of
Pioneer,  the fund (other than as trustees),  PGI or Pioneer Funds  Distributor,
Inc. (PFD); (k) the cost of preparing and printing share  certificates;  and (l)
interest on borrowed money, if any. In addition, the fund shall pay all brokers'
and  underwriting   commissions  chargeable  to  the  fund  in  connection  with
securities  transactions to which the fund is a party. The trustees' approval of
and the terms,  continuance  and  termination  of the  management  contract  are
governed by the 1940 Act and the Investment Advisers Act of 1940, as applicable.
Pursuant to the management contract, Pioneer will not be liable for any error of
judgment or mistake of law or for any loss  sustained  by reason of the adoption
of any investment policy or the purchase, sale or retention of any securities on
the  recommendation  of Pioneer.  Pioneer,  however,  is not  protected  against
liability by reason of willful misfeasance, bad faith or gross negligence in the
performance  of its  duties  or by  reason  of  its  reckless  disregard  of its
obligations and duties under the management contract.

     As compensation for its management  services,  Pioneer High Yield Fund will
pay Pioneer a fee equal to 0.70% of Pioneer High Yield Fund's  average daily net
assets up to $500 million;  0.65% of the next $500 million;  and 0.60% on assets
over $1  billion.  The fee is  normally  computed  and  accrued  daily  and paid
monthly.

     Pioneer High Yield Fund has entered into an  administration  agreement with
Pioneer  pursuant  to which  certain  accounting  and legal  services  which are
expenses  payable by the fund under the  management  contract  are  performed by
Pioneer and pursuant to which Pioneer is  reimbursed  for its costs of providing
such services.

     Pioneer  has  agreed  to  waive  all or  part of its  management  fee or to
reimburse  Pioneer High Yield Fund for other expenses (other than  extraordinary
expenses)  to the extent  the  fund's  Class A share  expenses  exceed  0.75% of
average daily net assets  attributable to Class A shares.  This agreement may be
revised or  terminated  at any time by  Pioneer.  If  Pioneer  waives any fee or
reimburses any expenses, and the expenses of the fund are subsequently less than
0.75% of the average daily net assets,  the fund will reimburse Pioneer for such
waived fees or reimbursed  expenses  provided that such  reimbursement  does not
cause the fund's expenses to exceed 0.75% of the average daily net assets.

             PIONEER HIGH YIELD FUND'S RULE 12b-1 DISTRIBUTION PLAN

     As described  above,  Pioneer High Yield Fund has adopted a Rule 12b-1 plan
for Class A shares.  Because these fees are an ongoing  expense,  over time they
increase the cost of your  investment  and your shares may cost more than shares
that are not subject to a distribution fee or a sales charge.

     Pursuant  to the Rule  12b-1  plan the fund will  reimburse  its  principal
underwriter,  PFD for its actual  expenditures to finance any activity primarily
intended  to  result  in the sale of Class A shares or to  provide  services  to
holders  of Class A  shares,  provided  the  categories  of  expenses  for which
reimbursement  is made are approved by the fund's board of trustees.  The fund's
board of trustees has approved the following  categories of expenses that may be
reimbursed  under the Class A plan:  (i) a service  fee to be paid to  qualified
broker-dealers  in an amount not to exceed  0.25% per annum of the fund's  daily
net  assets  attributable to  Class  A shares;  (ii)  reimbursement  to  PFD for


                                       19
<PAGE>

its  expenditures  for  broker - dealer commissions and employee compensation on
certain  sales of the fund's Class A shares with no initial  sales  charge;  and
(iii)  reimbursement to PFD for expenses incurred in providing services to Class
A shareholders and supporting  broker-dealers and other  organizations  (such as
banks and trust  companies)  in their  efforts to  provide  such  services.  The
expenses of the fund  pursuant to the plan are accrued daily at a rate which may
not  exceed  the annual  rate of 0.25% of the  fund's  average  daily net assets
attributable  to Class A shares.  Distribution  expenses of PFD are  expected to
substantially exceed the distribution fees paid by the fund in a given year. The
fund will not, however, pay such Rule 12b-1 fees on assets attributable to Class
A shares  issued in the  reorganization,  other  than  those  issued to  omnibus
accounts.

     The Rule 12b-1 plan does not  provide  for the  carryover  of  reimbursable
expenses  beyond  12  months  from the time  the fund is first  invoiced  for an
expense. The limited carryover provision in the Rule 12b-1 plan may result in an
expense  invoiced  to the fund in one fiscal  year being paid in the  subsequent
fiscal year and thus being  treated  for  purposes  of  calculating  the maximum
expenditures of the fund as having been incurred in the subsequent  fiscal year.
In the event of  termination  or  non-continuance  of the plan,  the fund has 12
months to reimburse  any expense  which it incurs prior to such  termination  or
non-continuance,  provided that payments by the fund during such 12-month period
shall not exceed 0.25% of the fund's  average daily net assets  attributable  to
Class A shares during such period.

           TRUSTEES AND EXECUTIVE OFFICERS OF PIONEER HIGH YIELD FUND

     When the  reorganization  occurs,  you will become a shareholder of Pioneer
High Yield Fund,  which is under  different  management  from Third  Avenue High
Yield Fund. Information regarding the trustees and executive officers of Pioneer
High Yield Fund is set forth below.

     The following  table sets forth each trustee's  position(s)  with the fund,
and age, address, principal occupation and employment during the past five years
and any other  directorships  held.  Each trustee  first became a trustee of the
fund on August 3, 1999. Because the fund is newly organized and not operational,
no trustee owns shares of the fund, beneficially or otherwise.

                       INFORMATION CONCERNING THE MEETING

SOLICITATION OF PROXIES

     In  addition  to the  mailing  of these  proxy  materials,  proxies  may be
solicited  by  telephone,  by fax or in person  by the  trustees,  officers  and
employees  of your fund;  by personnel of Pioneer,  EQSF  Advisers,  Inc. or the
fund's transfer agent, PNC Financial Processing Corporation,  Inc. (PFPC); or by
any of their  representatives  or compensated  agents,  including  broker-dealer
firms. Shareholder Communications  Corporation, a third-party solicitation firm,
has agreed to provide  proxy  solicitation  services  for your fund at a cost to
Pioneer of approximately $6,000.

REVOKING PROXIES

     A Third Avenue High Yield Fund  shareholder  signing and  returning a proxy
has the power to revoke it at any time before it is exercised:

o    By filing a written notice of revocation with the fund's Secretary, or

o    By returning a duly executed proxy with a later date before the time of the
     meeting, or

o    If a  shareholder  has  executed a proxy but is present at the  meeting and
     wishes to vote in  person,  by  notifying  the  fund's  secretary  (without
     complying with any formalities) at any time before it is voted

     Being  present at the meeting  alone does NOT revoke a previously  executed
and returned proxy.

OUTSTANDING SHARES AND QUORUM

     As of November 30, 1999,  800,597.863 shares of beneficial interest of your
fund were  outstanding.  Only  shareholders  of record on  December 3, 1999 (the
record date) are entitled to notice of and to vote at the meeting. A majority of
the outstanding shares of your fund that are entitled to vote will be considered
a quorum for the transaction of business.

OTHER BUSINESS

     Your fund's  board of trustees  knows of no  business to be  presented  for
consideration  at the  meeting  other than the  proposal.  If other  business is
properly brought before the meeting, proxies will be voted according to the best
judgment of the persons named as proxies.

ADJOURNMENTS

     If a quorum is not present in person or by proxy at the time any session of
the  meeting is called to order,  the  persons  named as proxies  may vote those
proxies  that have been  received to adjourn  the meeting to a later date.  If a
quorum is present but there are not  sufficient  votes in favor of the proposal,
the persons named as proxies may propose one or more adjournments of the meeting
to  permit  further  solicitation  of  proxies  concerning  the  proposal.   Any
adjournment  will  require  the  affirmative  vote of a majority  of your fund's
shares at the session of the meeting to be adjourned.  If an  adjournment of the
meeting  is  proposed  because  there are not  sufficient  votes in favor of the
proposal,  the persons  named as proxies  will vote those  proxies  favoring the
proposal  in favor of  adjournment,  and will vote  those  proxies  against  the
reorganization against adjournment.

TELEPHONE VOTING

     In addition to soliciting  proxies by mail, by fax or in person,  your fund
may also arrange to have votes  recorded by telephone by officers and  employees
of your fund or by  personnel  of Pioneer,  EQSF  Advisers,  Inc. or your fund's
transfer  agent,  or by  representatives  of compensated  agents of any of these
parties.  The telephone  voting  procedure is designed to verify a shareholder's
identity, to allow a shareholder to authorize the voting of shares in accordance
with the shareholder's  instructions and to confirm that the voting instructions
have been properly  recorded.  If these  procedures were subject to a successful
legal challenge, these telephone votes would not be counted at the meeting. Your
fund has not  obtained  an opinion of counsel  about  telephone  voting,  but is
currently not aware of any challenge.

o    A  shareholder  will be  called  on a  recorded  line  and will be asked to
     provide  the  shareholder's  social  security  number or other  identifying
     information

o    The shareholder  will then be given an opportunity to authorize  proxies to
     vote his or her shares at the meeting in accordance with the  shareholder's
     instructions

o    To ensure that the shareholder's instructions have been recorded correctly,
     the shareholder will also receive a confirmation of the voting instructions
     by mail

o    A  toll-free  number  will be  available  in case  the  voting  information
     contained in the confirmation is incorrect

                                       24
<PAGE>


o    If the shareholder decides after voting by telephone to attend the meeting,
     the  shareholder  can  revoke the proxy at that time and vote the shares at
     the meeting

                                    EXHIBIT A

                      AGREEMENT AND PLAN OF REORGANIZATION

     THIS AGREEMENT AND PLAN OF  REORGANIZATION  (the "AGREEMENT") is made as of
this 10th day of December, 1999, between Pioneer High Yield Fund (the "ACQUIRING
FUND"),  a business trust organized under the laws of the State of Delaware with
its principal place of business at 60 State Street, Boston, Massachusetts 02109,
and Third Avenue Trust, a business trust  organized  under the laws of the State
of Delaware with its principal place of business at 767 Third Avenue,  New York,
New York  10017-2023  (the  "TRUST"),  on behalf of Third Avenue High Yield Fund
(the "ACQUIRED FUND"), a series of the Trust.

     This Agreement is intended to be and is adopted as a plan of reorganization
within the meaning of Section 368(a) of the United States Internal  Revenue Code
of 1986, as amended (the "CODE"). The reorganization (the "REORGANIZATION") will
consist of (a) the  transfer  of all of the assets of the  Acquired  Fund to the
Acquiring  Fund in exchange for (i) the issuance of Class A shares of beneficial
interest of the Acquiring Fund  (collectively,  the "ACQUIRING  FUND SHARES" and
each, an "ACQUIRING  FUND SHARE") to the Acquired  Fund, and (ii) the assumption
by the  Acquiring  Fund of (I) the  liabilities  of the  Acquired  Fund that are
included in the  calculation  of net asset value ("NAV") on the closing date set
forth below (the "CLOSING  DATE") and (II) the  liabilities of the Acquired Fund
with  respect to its  investment  operations  that are not required by generally
accepted accounting principles ("GAAP") to be included in the calculation of NAV
consistent  with  liabilities  incurred  by  registered   management  investment
companies in the ordinary course of their  businesses  (i.e.,  not including any
extraordinary  obligations,  including,  but not  limited to legal  proceedings,
shareholder claims and distribution payments) (the "ASSUMED  LIABILITIES"),  and
(b) the  distribution  by the Acquired  Fund,  on the Closing  Date,  or as soon
thereafter as practicable,  of the Acquiring Fund Shares to the  shareholders of
the Acquired Fund in liquidation of the Acquired Fund and the termination of the
Acquired Fund, all upon the terms and conditions  hereinafter  set forth in this
Agreement.

     WHEREAS,  Acquiring  Fund  and the  Trust  are each  registered  investment
companies  classified  as  management  companies of the open-end  type,  and the
Acquired  Fund owns  securities  that  generally  are assets of the character in
which the Acquiring Fund is permitted to invest;

     WHEREAS,  the  Acquiring  Fund is  authorized to issue shares of beneficial
interest;

     WHEREAS,  the Board of Trustees of the Acquiring Fund has  determined  that
the exchange of all of the assets of the Acquired Fund for Acquiring Fund Shares
and the  assumption  of the  Assumed  Liabilities  of the  Acquired  Fund by the
Acquiring Fund are in the best interests of the Acquiring Fund shareholders;

     WHEREAS,  the  Board of  Trustees  of the  Trust  has  determined  that the
exchange of all of the assets of the Acquired Fund for Acquiring Fund Shares and
the assumption of the Assumed  Liabilities of the Acquired Fund by the Acquiring
Fund are in the best interests of the Acquired Fund shareholders.

     NOW,  THEREFORE,  in consideration of the premises and of the covenants and
agreements  hereinafter  set forth,  the parties  hereto  covenant  and agree as
follows:

1.   TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR THE ACQUIRING  FUND
     SHARES AND  ASSUMPTION  OF THE  ASSUMED  LIABILITIES  AND  LIQUIDATION  AND
     TERMINATION OF THE ACQUIRED FUND.

     1.1. Subject to the terms and conditions  herein set forth and on the basis
of the representations and warranties contained herein, the Acquired Fund agrees
to transfer its assets as set forth in paragraph 1.2 to the Acquiring  Fund free
and clear of all liens and  encumbrances  (other  than those  arising  under the
Securities Act of 1933, as amended (the "SECURITIES  ACT"),  liens for taxes not
yet due and contractual  restrictions  on the transfer of the acquired  assets),
and the Acquiring Fund agrees in exchange therefor: (a) to issue to the Acquired
Fund the number of Acquiring Fund Shares,  including  fractional  Acquiring Fund
Shares, determined (to at least two decimal places) by dividing the value of the
Acquired Fund's net assets  transferred to the Acquiring  Fund,  computed in the
manner and as of the time and date set forth in paragraph 2.1, by the NAV of one
Acquiring  Fund  Share,  computed  in the manner and as of the time and date set
forth in paragraph 2.2; and (b) to assume the Assumed Liabilities,  as set forth
in paragraph 1.3. Such transactions shall take place at the closing provided for
in paragraph 3.1 (the "CLOSING").

     1.2.  (a) The assets of the Acquired  Fund to be acquired by the  Acquiring
Fund shall consist of all of its property,  including,  without limitation,  all
goodwill, all contractual rights of the Acquired Fund or the Trust in respect of
the Acquired Fund, all other intangible  property owned by the Acquired Fund and
originals or copies of all books and records of the Acquired  Fund but shall not
include any interest in the name "Third Avenue."

           (b) The Acquired Fund has provided the Acquiring Fund with a  list of
all  of  the  Acquired  Fund's  securities  and  other  assets as of the date of
this  Agreement.  The  Acquired  Fund  reserves  the  right to sell any of these
securities  but will not,  without  the prior  approval of the  Acquiring  Fund,
acquire any additional securities other than securities of the type in which the
Acquiring Fund is permitted to invest


                                       26
<PAGE>


and  shall  not  acquire,  without  the  consent  of  the  Acquiring  Fund,  any
securities  that are valued at "fair value" under the  valuation  procedures  of
either the Acquired Fund or the Acquiring Fund.

     1.3. The Acquired Fund will  endeavor to discharge all the Acquired  Fund's
known  liabilities  and  obligations  that are or will  become  due prior to the
Closing Date.  The Acquired Fund shall prepare an unaudited  statement of assets
and liabilities (the "CLOSING STATEMENT"),  as of the Valuation Date (as defined
in paragraph 2.1), in accordance with GAAP  consistently  applied from the prior
audited  period,  including a calculation of the net assets of the Acquired Fund
as of the close of business on the Closing Date. The Acquiring Fund shall assume
the Assumed Liabilities.

     1.4.  On  the  Closing  Date  or as  soon  thereafter  as  is  conveniently
practicable, the Trust shall liquidate the Acquired Fund and distribute pro rata
to the Acquired  Fund's  shareholders  of record  determined  as of the close of
business on the Closing Date (the  "ACQUIRED FUND  SHAREHOLDERS")  the Acquiring
Fund  Shares it  receives  pursuant  to  paragraph  1.1.  Such  liquidation  and
distribution will be accomplished by the Trust instructing the Acquiring Fund to
transfer the Acquiring  Fund Shares then credited to the account of the Acquired
Fund on the books of the Acquiring Fund to open accounts on the share records of
the Acquiring Fund in the names of the Acquired Fund  Shareholders  (as provided
to the Acquiring  Fund by the Trust) and  representing  the  respective pro rata
number of the  Acquiring  Fund  Shares due such  shareholders.  The Trust  shall
promptly  provide  the  Acquiring  Fund with  evidence of such  liquidation  and
distribution.  All  issued  and  outstanding  shares of the  Acquired  Fund will
simultaneously  be cancelled on the books of the Acquired  Fund,  although share
certificates representing interests in the Acquired Fund will represent a number
of Acquiring Fund Shares after the Closing Date as determined in accordance with
paragraph 1.1. The Acquiring Fund shall not issue certificates  representing the
Acquiring Fund Shares in connection with such exchange.

     1.5.  Ownership of Acquiring  Fund Shares will be shown on the books of the
Acquiring  Fund's  transfer agent for its Class A shares.  Acquiring Fund Shares
will be issued in the manner  described  in the  Acquiring  Fund's  Registration
Statement on Form N-14 in the form attached to this Agreement as Annex A.

     1.6. Any transfer  taxes payable upon issuance of the Acquiring Fund Shares
in a name other than the  registered  holder of the Acquired  Fund shares on the
books of the Acquired Fund as of the time of issuance  shall,  as a condition of
such issuance and transfer,  be paid by the person to whom such  Acquiring  Fund
Shares are to be issued and transferred.

     1.7. Any reporting responsibility of the Trust with respect to the Acquired
Fund is and shall remain the responsibility of the Trust up to and including the
Closing Date and such later date on which the Acquired Fund is terminated.

     1.8. The Acquired Fund shall,  following the Closing Date and the making of
all  distributions  pursuant to paragraph  1.4, be terminated as a series of the
Trust under the laws of the State of Delaware and in  accordance  with the Trust
Instrument and By-Laws of the Trust.

2.   VALUATION

     2.1.  The value of the assets of the  Acquired  Fund to be  acquired by the
Acquiring  Fund hereunder  shall be the value of such assets  computed as of the
close of regular  trading on the New York Stock  Exchange,  Inc.  on the Closing
Date (such time and date being hereinafter called the "VALUATION  DATE"),  using
the valuation  procedures set forth in the prospectus or statement of additional
information of the Acquired Fund as in effect on the date hereof.

     2.2. The NAV of the  Acquiring  Fund Class A shares shall be  calculated in
accordance with the valuation procedures described in paragraph 2.1.

     2.3. All  computations  of value shall be made by PNC Financial  Processing
Corporation,  Inc. in accordance with its regular  practice as pricing agent for
the Acquired Fund.

3.   CLOSING AND CLOSING DATE

     3.1. The Closing Date shall be February 25, 2000, or such later date as the
parties may agree to in writing.  All acts taking place at the Closing  shall be
deemed to take place  simultaneously  as of the close of business on the Closing
Date  unless  otherwise  provided.  The  Closing  shall be held as of 5:00  p.m.
(Eastern  time) at the  offices of Hale and Dorr LLP, 60 State  Street,  Boston,
Massachusetts, or at such other time and/or place as the parties may agree.

     3.2. Portfolio  securities shall be presented by the Acquired Fund to Brown
Brothers  Harriman  & Co.  ("BBH")  as  custodian  for the  Acquiring  Fund  for
examination no later than three business days preceding the Valuation  Date. The
Acquiring  Fund  may,  in its  sole  discretion,  reject  any  securities  if it
reasonably  believes that the ownership of such  securities by the Acquired Fund
or the  acquisition  of such  securities by the Acquiring Fund would violate the
investment  policies and  restrictions  of the Acquired  Fund and the  Acquiring
Fund.  The  portfolio  securities,  cash and due bills shall be delivered by the
Acquired Fund to BBH as custodian for the Acquiring  Fund for the account of the
Acquiring  Fund at the Closing duly endorsed in proper form for transfer in such
condition as to constitute  good delivery  thereof in accordance with the custom
of brokers.  The cash shall be delivered by wire in federal  funds to an account
of the Acquiring Fund specified by the Acquiring Fund.


                                       27
<PAGE>


     3.3.  Custodial  Trust  Company,  custodian  for the Acquired  Fund,  shall
deliver at the Closing a certificate of an authorized  officer stating that: (a)
the Acquired  Fund's assets have been  delivered in proper form to the Acquiring
Fund on the Closing Date and (b) all  necessary  transfer  taxes  including  all
applicable  federal and state stock transfer stamps,  if any, have been paid, or
provision for payment shall have been made, in conjunction  with the delivery of
portfolio securities.

     3.4. In the event that on the Valuation Date (a) the primary trading market
for  portfolio  securities  of the  Acquired  Fund shall be closed to trading or
trading  thereon  shall be restricted or (b) trading or the reporting of trading
on such  market  shall be  disrupted  so that  accurate  calculation  based upon
available  market prices of the value of the net assets of the parties hereto is
impracticable,  the Closing Date shall be postponed until the first business day
after the day when trading  shall have been fully  resumed and  reporting  shall
have been restored,  provided that unless the parties  otherwise  agree,  if the
transactions  contemplated by this Agreement shall not have occurred on or prior
to April 15, 2000, each party's obligations under this Agreement shall terminate
without  liability to the other party,  except for any liability  that may arise
out of a party's breach of its  obligations  under this Agreement  prior to such
termination.

     3.5. The Acquired Fund shall  deliver to the Acquiring  Fund at the Closing
(or,  if not  reasonably  available  at the  Closing,  as  soon  as  practicable
thereafter) a list of the names, addresses,  taxpayer identification numbers and
backup withholding and nonresident alien withholding status of the Acquired Fund
Shareholders and the number and percentage ownership of outstanding shares owned
by each such  shareholder  immediately  prior to the  Closing,  certified by the
President or a Vice  President  of the Trust on behalf of the  Acquired  Fund as
being an accurate  record of the  information  (i)  provided  by  Acquired  Fund
Shareholders or (ii) derived from the Trust's records by such officers or one of
the Trust's service providers.

     3.6. The Acquiring Fund shall issue and deliver a  confirmation  evidencing
the Acquiring  Fund Shares to be credited to the Acquired  Fund's account on the
Closing Date to the  Secretary of the Trust on behalf of the Acquired  Fund,  or
provide  evidence  satisfactory  to the Acquired Fund that such  Acquiring  Fund
Shares have been  credited to the  Acquired  Fund's  account on the books of the
Acquiring Fund. At the Closing, each party shall deliver to the other such bills
of sale,  checks,  assignments,  share  certificates,  if any, receipts or other
documents as such other party or its counsel may reasonably request.

4.   LIQUIDATION AND DISSOLUTION OF ACQUIRED FUND

     4.1. As soon as practicable  after the Closing,  the Trust shall  liquidate
the Acquired Fund and distribute pro rata to the Acquired Fund  Shareholders the
Acquiring Fund Shares received  pursuant to paragraph 1.1. Such  liquidation and
distribution  will be  accomplished by the transfer of the Acquiring Fund Shares
credited  to the  account of the  Acquired  Fund to open  accounts  on the share
records in the names of Acquired Fund Shareholders as delivered to the Acquiring
Fund prior to the Closing Date in accordance with paragraph 3.5 and representing
the  respective pro rata  entitlement  of each Acquired Fund  Shareholder in the
Acquiring Fund Shares.

     4.2. In connection with such liquidating  distributions,  (a) the Acquiring
Fund shall not deliver  certificates  representing  its shares and (b) the share
transfer  books of the  Acquired  Fund  shall be  permanently  closed  as of the
Closing  Date  and  arrangements  satisfactory  to the  Acquiring  Fund,  acting
reasonably,  shall be made to  restrict  the further  transfer  of the  Acquired
Fund's shares.

     4.3. As soon as practicable after the liquidation of the Acquired Fund, the
Trust shall  terminate the Acquired Fund as a series of the Trust under the laws
of the State of Delaware and in accordance with the Trust Instrument and By-Laws
of the Trust.

5.   REPRESENTATIONS AND WARRANTIES

     5.1. The Trust, on behalf of the Acquired Fund,  represents and warrants to

                  EXCERPTS FROM THIRD AVENUE HIGH YIELD FUND'S

      APRIL 30, 1999 SEMI-ANNUAL REPORT AND OCTOBER 31, 1998 ANNUAL REPORT

     The following  information  is provided for your  convenience.  It has been
excerpted  in its  entirety  from Third  Avenue  High Yield  Fund's  most recent
semi-annual  and annual  reports,  both of which were mailed to  shareholders of
Third Avenue High Yield Fund.  Specifically,  these excerpts contain your fund's
portfolio manager's  discussion of portfolio holdings and factors affecting fund
performance.

                   EXCERPT FROM THIRD AVENUE HIGH YIELD FUND'S
                        APRIL 30, 1999 SEMI-ANNUAL REPORT



Dear Fellow Shareholders:

At  April  30,  1999,  the  unaudited  net  asset   value  attributable  to  the
916,197  common  shares  outstanding  of the Third  Avenue  High Yield Fund (the
"Fund") was $9.41 per share.  On March 31, 1999, the most recent  dividend date,
the Fund paid $0.167 per share in dividends,  representing  income received from
the Fund's holdings of fixed income securities. Since the end of the Fund's last
fiscal  year,  ending on October 31,  1998,  when the Fund's net asset value was
$8.50,  a total of $0.35 per share has been paid in  dividends.  On January  31,
1999, the last day of the Fund's first fiscal  quarter,  the net asset value per
share was $9.58. At May 20, 1999, the net asset value per share was $9.64.

QUARTERLY ACTIVITY

During  the  second  quarter  of  fiscal 1999, the Fund made small reductions in
three holdings, and established three new positions, as shown below.

PAR VALUE
OR NUMBER OF SHARES                 REDUCTIONS IN EXISTING POSITIONS
$100,000                            Alpharma, Inc. 144A 5.75% due 4/01/05
$100,00                             Credence Systems Corp. 5.25% due 9/15/02
1,000 shares                        Nextlink Communications, Inc. 144A 6.50%
                                    due 3/31/10

These  reductions  were  made  in  order  to better reflect what we thought were
appropriate weightings for these holdings,  given their substantial appreciation
at the time of their  sales in the  fiscal  year.  We  continue  to  regard  the
business prospects of these companies favorably,  and expect to retain our still
significant positions.

Alpharma  is  a generic  pharmaceutical  company   which  develops  and  sells a
wide range of human and animal health products worldwide, and has grown steadily
through development of new products and selected acquisitions.

Credence  Systems  makes  automatic  test equipment  and  software  used  in the
production of  semiconductors.  It sells its products worldwide to semiconductor
makers, and after some delays in the introduction of new products, should have a
good increase in sales as these products have been received  quite  favorably by
its customers. Its equipment is increasingly focused on the most rapidly growing
segments of the semiconductor market: those used in telecommunications, internet
applications, media and consumer devices.

Nextlink  is  a  new  telecommunications  company established in 1996 to provide
local, long distance and data communication  services. The company was formed to
take advantage of the many growth  opportunities  in the industry  following the
federal   telecommunication   act  of   1996   which   opened   competition   in
telecommunication services to new entrants.

PAR VALUE
OR NUMBER OF SHARES                 NEW POSITIONS ACQUIRED
$500,000                            Webb (Del E.) Corp. 10.25% due 2/15/10
4,000 shares                        KN Energy, Inc. 8.25% due 11/30/01
$250,000                            NCI Building Systems, Inc. 144A 9.25%
                                    due 5/01/09

Del  Webb  is  one  of  the US's biggest residential real estate developers, and
the nation's largest developer of planned age-restricted retirement communities,
with operations primarily in the sunbelt states of Nevada, Arizona,  California,
Florida, and South Carolina, as well as in Illinois.  Recently,  the company has
expanded  its  development  activities  to include  communities  without the age
restrictions.  It has an excellent track record,  diversified locations,  and is
well  positioned  for the  move-up  buyer,  as well as the active  adult  market
segment.

KN  Energy  gathers,  processes,  stores  and   transports   natural   gas,  and
operates  pipelines  in the central and  western  US. It is the  nation's  sixth
largest integrated natural gas company.  Above-normal  winter  temperatures have
reduced  demand for natural gas,  and the  resulting  depressed  prices for gas,
along with low oil prices,  have recently caused  financial  results to decline.
However, the company is well run, has diversified  operations,  and earnings are
expected to recover with more normal  seasonal  temperatures  and higher  energy
prices in general.  Recently,  Sempra Energy  offered to acquire KN Energy.  San
Diego-based  Sempra has  started  the process of  restructuring,  as  California


                                       35
<PAGE>


begins to deregulate  the retail power market,  and has sold some assets,  while
expanding  further  into the gas  industry,  through  its offer to  purchase  KN
Energy.  The credit  quality of KN Energy  would be improved if the  acquisition
were made, since Sempra's corporate debt is A-rated,  or one level above that of
KN Energy.

NCI   Building   Systems   was   substantially   expanded  a year  ago  with the
acquisition of a major competitor.  The company is one of the largest integrated
manufacturers of metal products for the  nonresidential  building  industry.  It
operates  in 17 states and  Mexico.  NCI makes and sells  metal  components  and
engineered  building  systems  such as metal  roof and wall  systems;  overhead,
interior  and  exterior  doors;  and  related  accessories,   both  to  the  new
construction  and renovation  markets.  With its recent  acquisition,  it is now
twice as large as its next competitor,  has substantial purchasing power because
of its size in a fragmented market, and has proprietary techniques for producing
higher margin coated metal products.  Metal roofing products comprise only 6% of
the $21 billion  roofing  market,  but this  segment is growing  faster than the
industry as a whole due to low cost,  flexibility  of use, and  improvements  in
function and appearance.

PORTFOLIO STRUCTURE

The table below lists our largest sector concentrations for the portfolio as of
April 30, 1999, reflecting our emphasis on industries which we feel represent
attractive value.

INDUSTRY                            PERCENTAGE OF TOTAL ASSETS
Telecommunications                          14.54%
Semiconductor capital equipment             13.66%
Diversified technology                      12.33%
Real estate                                 11.56%
Electric and gas utilities                  10.58%

We  think  the  telecommunications  industry  remains  an  excellent investment,
and have made a substantial commitment. Lower prices, faster transmission speed,
and   greater   functionality   have   dramatically   changed   the   nature  of
telecommunications  in the last few years, and these trends should continue into
the future.  Usage of  traditional  voice services has expanded much faster than
growth of the general  economy,  as falling prices have  stimulated  demand.  In
addition,  increasing amounts of data are being transported as information needs
grow.  New  demand  for an  enlarged  range of data,  video and voice  services,
spawned by ever growing internet usage, has also dramatically multiplied.

Increased  uses  of  semiconductors  in  a  widening  array of products continue
to drive the revenues of technology  companies,  for both SEMICONDUCTOR  CAPITAL
EQUIPMENT  issuers,  and  in  other  TECHNOLOGY  based  companies.  The  capital
equipment  sector  has  bottomed  out from a two year  cyclical  decline  in new
capacity,  but  early  indications  are that an  upswing  in new  investment  is
underway.  Technology demand is growing not only from augmenting computer sales,
but also from  telecommunications'  increased  utilization of complex chips,  as
discussed  above.  In  addition,  industrial  processes  and  consumer  products
continue to incorporate  more  intelligence on chips to increase  efficiency and
performance characteristics, and always at continuously declining prices.

We  believe  increasing  use  of  intelligent silicon has been a big contributor
to the  higher  productivity  of the  American  worker  over the past few years.
Technology  comprises  an ever  larger  share  of our  economic  activity,  with
constantly falling prices, yet offering much higher  functionality.  So we think
the Fund should reflect these positive trends through the industries in which we
invest.

We  regard  the  REAL  ESTATE  sector  as  undervalued,  and  therefore  we have
moderately  increased  our  exposure  to  this  area,  as  discussed  in the new
purchases section above. Our positive view of real estate is shared by our other
Third Avenue funds, which have also increased their commitments.

Our  investment  in  the  ELECTRIC  AND  GAS  UTILITY  industry has grown in the
quarter. We consider this sector to be under-appreciated  by many investors.  We
think that deregulation of the retail market, now proceeding on a state by state
basis,  will create  opportunities  for  well-run  companies to  restructure  by
selling  under-performing assets, and to increase their investment in activities
which will expand their operations and improve their efficiency.

We  want  to  keep  the  portfolio  positioned  in  front of these  high  growth
trends,  as well as to  emphasize  those areas that are  undervalued  in today's
often fickle and short-term oriented marketplace.

Sincerely,



/s/ Margaret D. Patel

                   EXCERPT FROM THIRD AVENUE HIGH YIELD FUND'S
                         OCTOBER 31, 1998 ANNUAL REPORT



Dear Fellow Shareholders:

At  October  31,  1998,  the  audited   net  asset   value  attributable  to the
904,440  common  shares  outstanding  of the Third  Avenue  High Yield Fund (the
"Fund") was $8.50 per share.  This compares with an unaudited net asset value of
$9.82 at July 31,  1998,  and a net asset  value of $10.00 per share at February
12, 1998, the date of the Fund's inception.  At December 11, 1998, the unaudited
net asset value was $9.00 per share.

QUARTERLY ACTIVITY

During  the  fourth   quarter of  fiscal  1998,  the  Fund  established  one new
position,  as new monies flowed into the Fund, and eliminated three positions in
order to raise cash to accommodate redemptions of shares by short-term investors
on several occasions.

Transactions made during the quarter are summarized below.

PAR VALUE                           NEW POSITION ACQUIRED
$500,000                            CalEnergy Co., Inc 8.48%, due 9/15/28

                                    POSITIONS ELIMINATED
$300,000                            Alcatel SA 7.00%, due 8/01/04
$300,000                            MascoTech 4.50%, due 12/15/03
$500,000                            PSINet, Inc. 10.00%, due 2/15/05

PORTFOLIO ACTIVITY

The  three  months  ending  October  31  marked  a  once-in-a-decade  chance for
investors  in the high  yield  bond  market,  where  the  Fund  has  substantial
investments,  to profit from disorderly  market  conditions.  Because of lack of
liquidity and forced sales from leveraged investors, yields rose to levels which
on a relative basis were at least as attractive as in the 1990-1991 period,  the
last such great unsettled period.  Similarly,  convertible bonds, where the bulk
of the Fund's  assets is  currently  concentrated,  dropped to levels  seen only
fleetingly in 1990.  Convertible  bonds  suffered  from the combined  effects of
lower stock prices and higher interest rates on below  investment grade bonds in
general.

We  believe  the  Fund's   portfolio   of  securities  offers both high  current
income and the possibility of future capital appreciation. Further, our holdings
are  concentrated  in companies and  industries  whose profits,  we think,  will
expand faster than the economy as a whole,  either through internal growth or in
combination with  restructuring  and consolidating  among companies.  Such asset
transfer  activity  can  improve  profits  and  return  on  investment  even  in
businesses with slow underlying growth rates.

Our  largest  concentration  of  holdings,  comprising  just  over  14% of total
assets, is in the semiconductor  capital equipment industry.  Our companies hold
leading  technological  positions  in  this  multifaceted  area,  and  have  the
financial   flexibility   to  ride  out  the  rest  of  the   current   industry
consolidation.  We  believe  they are  well  positioned  for the  next  industry
upswing, which some industry analysts think is already underway.

Our  second  largest  industry  representation,   about  13.5%  of total assets,
consists  of issues of  corporations  manufacturing  a wide range of  technology
products such as  semiconductors,  networking  products and disks for computers.
Companies in these  industries  have just completed a period of relatively  flat
demand,  coupled  with the  worst  excess  inventory  supply  cycle  seen in the
post-World War II period, causing sharp price erosion as inventories were worked
off. This process is nearly completed, and demand, especially for computer-based
products, seems to be moving up again at very healthy rates.

The  third   largest  sector  in  the  Fund,  amounting  to  11% of  assets,  is
telecommunications.  This industry is undergoing  dynamic  change as a result of
the   Telecommunications   Act  of  1996.  This  legislation  provided  for  the
deregulation of the industry and has spawned a number of aggressive  competitors
offering voice, data, and internet services using new technology to share in the
explosive growth in demand. We hold issues of several of these new entrants, and
think they will profit not only from new markets but also by taking market share
from existing incumbent service providers.

Healthcare  makes  up  close  to 11%  of  the   Fund's  total   assets.  Current
industry  conditions  are unsettled,  as long-term  care providers  adjust their
business plans to new federal government  regulations on reimbursement for care.
The number of people needing  long-term  care along with  ancillary  services is
growing much faster than the population as a whole.  Once companies adapt to the
new reimbursement  rules being phased into the system, we expect other investors
will recognize their bright future,  as demand for both the quantity and quality
of healthcare expands faster than growth of the domestic economy.

The   electric   and   gas   utility   industry   is our  fifth  largest sector,
amounting to close to 10% of the Fund's total assets. While this industry should
grow at levels in line with overall economic growth in the U.S., massive changes
are just starting to be felt as states begin to deregulate  the power  industry.
Similar  deregulation  moves  are  also  going  on in  industrialized  countries
overseas,  which in some cases,  notably the United Kingdom (U.K.), are actually
ahead of the U.S. in opening their power markets to free  competition.  We think
smart  managements will be able to take advantage of these changes to grow their
revenues and profits far above the growth of the power market as a whole.


                                       37

Further,  the  electric  utility  industry  in the U.S. and other industrialized
countries is  relatively  insensitive  to the recent  economic  declines in less
industrialized, so-called emerging market countries, primarily in Asia and Latin
America.  These  countries  have begun to reduce their demand for many  products
manufactured  in the U.S.,  and are  attempting  to  increase  their  exports to
industrialized  countries,  in an effort to solve their economic troubles.  As a
result of this lowered export demand and increased import supply,  many domestic
companies,  especially those in commodity-based  industries like metals, energy,
chemicals,  paper and forest products, and textiles, will experience revenue and
profit pressure next year.

NEW PURCHASE

CalEnergy   is  a   diversified   global   energy  company  which  has  grown by
acquisition of electric and gas companies in the U.S., U.K., Australia,  Canada,
and New  Zealand.  Its recent  purchase of  Iowa-based  MidAmerican  Energy will
provide access to an attractive  and growing  market for its low cost power.  As
the electric utility industry begins to deregulate, both in the U.S. and abroad,
CalEnergy  should  benefit  from the  knowledge  it has  gained  since  its 1997
acquisition of Northern Electric in the U.K.

POSITIONS ELIMINATED

Among  the  three  positions  which  were  eliminated  in the quarter were bonds
of Alcatel, the large French  telecommunications  equipment company. Alcatel had
agreed  in  June,  1998,  to  take  over  DSC   Communications,   a  Texas-based
telecommunications  equipment  company.  The DSC bonds had a  speculative  grade
rating  of  "B"  by the  major  rating  services,  and  experienced  substantial
appreciation in price due to Alcatel's higher  investment grade credit rating of
"A" by the major rating agencies.

MascoTech  convertible  bonds  were  sold,  although our fundamentally favorable
opinion of the company has not  changed,  because we felt other  holdings in the
portfolio had a likelihood of greater capital appreciation.  Similarly,  we also
sold our  holding of PSINet,  an  Internet  access and Web  hosting  provider to
corporations  and  other  Internet  service  providers,   because  we  felt  its
continuing  need to tap the high yield bond market at future dates would provide
other opportunities to reestablish a position in this credit in the future.

THE MISFORTUNE OF MARKET TIMING

Notably,  redemptions  of  the  Fund  in  the quarter were  concentrated  during
the first half of October,  the very period when financial markets were at their
most stressed condition in many years, and short-term downward pressure was most
intense on all securities  prices.  You may recall that at this time,  prices of
virtually all securities, except for U.S. Treasury issues, declined sharply, due
to  liquidity  pressures  arising from forced  sales of  securities  by numerous
leveraged  investment  funds.  In  addition,  credit  concerns  about  so-called
emerging market bonds, such as those from Russia which defaulted in the quarter,
caused  prices of all emerging  market debt,  as well as prices of domestic high
yield bonds, to drop  significantly.  The combination of all these events led to
extremely illiquid market conditions not seen in many years.

Of  course,  we  recognize  that  in  future periods of market turmoil,  the net
asset  value per share of the Fund may well drop  again,  reflecting  short-term
changes in the prices of  securities  held in the Fund.  We regard such times as
great  opportunities to purchase,  but certainly not to sell. Lower prices allow
us to buy more bonds or shares for the same  amount of money.  If our  intensive
research  evaluations  are accurate,  we can take advantage of short-term  price
declines to create  even  greater  opportunity  to  increase  our  shareholders'
investment over the long term.

1998 DISTRIBUTIONS

On   November   18,   1998,  the  Fund   declared  a  dividend  from the  Fund's
estimated net investment income through the period ending December 31, 1998. The
amount is estimated to be approximately  $0.16 per Fund share. This distribution
is payable January 6, 1999 to Fund  shareholders of record on December 30, 1998.
The precise  amount of the  distribution  will be determined  based on the total
number of Fund shares  outstanding  on the close of business on the record date,
December  30,  1998.  The   distribution  is  payable  in  cash  or,  for  those
shareholders who have elected the reinvestment option, in additional Fund shares
at the Fund's net asset value on December 31, 1998,  the "ex" date, or valuation
date, for reinvestment.

I  look  forward  to  writing  to  you again when the first  quarter  report for
the period ending January 31, 1999 is published.

Sincerely,



/s/ Margaret D. Patel
