PROSPECTUS-MAY 1, 2000
- -------------------------------------------------------------------------------

positive social impact.

   The Trust has three funds. The Equity Income Fund invests primarily in stocks
that pay a dividend,  and its  investment  objective is both current  income and
capital appreciation. The Fixed-Income Fund invests primarily in bonds and other
fixed-income  investments,  and its  investment  objective  is a high  level  of
current  income  consistent  with  safety  and  preservation  of  capital.   The
California Tax-Exempt Fund (for California residents only) has as its investment
objective  a high level of current  income  exempt from  federal and  California
personal income tax consistent with prudent investment management.

INVESTMENT SUMMARY
- --------------------------------------------------------------------------------

                               Equity Income Fund

Investment Objective and Principal Strategies

   The Parnassus Equity Income Fund invests primarily in a diversified portfolio
of equity  securities.  Its  investment  objective  is both  current  income and
capital  appreciation.  Equity securities  include common and preferred stock as
well as convertible bonds. At least 75% of the Fund's total assets will normally
be invested in equity  securities that pay interest or dividends.  The remaining
25% may be invested in  non-dividend  paying  equity  securities,  in investment
grade debt securities or money market  instruments.  The Fund seeks to invest in
equity  securities  that pay  above-average  dividends  and  which  the  Adviser
believes  have the  capacity to raise  dividends in the future and also have the
potential  for capital  appreciation.  To determine a company's  prospects,  the
Adviser  reviews the company's  profit and loss statement,  sales,  earnings and
dividend histories, net cash flow and outlook for future earnings.

   The Fund takes  social as well as  financial  factors  into account in making
investment  decisions.  In general,  The Parnassus  Equity Income Fund looks for
companies  that  respect the  environment,  treat  their  employees  well,  have
effective equal employment  opportunity policies and good community relations as
well as ethical  business  dealings.  The Fund will not invest in companies that
are involved with gambling or manufacture alcohol or tobacco products.  The Fund
also screens out weapons  contractors and those that generate  electricity  from
nuclear power.

Principal Risks of Investing in the Equity Income Fund

   Investing  in the Fund may  result  in a loss of  money.  When you sell  your
shares,  they may be worth more or less than what you paid for them.  The Fund's
share price changes daily based on the value of its holdings.  Stock markets are
volatile  and stock values  fluctuate in response to the fortunes of  individual
companies and in response to general  market and economic  conditions  both here
and abroad.  The Fund's holdings can vary  significantly from broad stock market
indexes. As a result, the Fund's performance can deviate from the performance of
these indexes. For best results,  investors should have a long-term  perspective
and plan to hold their shares for at least three years.  (Legally,  shareholders
may redeem at any time,  but the Fund manager  recommends  a minimum  three-year
holding period.)

Performance Information for the Equity Income Fund

   The bar chart below  provides an  indication of the risks of investing in the
Parnassus  Equity Income Fund by showing changes in the Fund's  performance from
year to year over a seven-year  period.  Prior to April 1, 1998,  the  Parnassus
Equity Income Fund had a different investment objective,  maintaining a balanced
portfolio  of both stocks and bonds.  How the Fund  performed in the past is not
necessarily an indication of how the Fund will perform in the future.

   During the seven-year period shown in the bar chart, the highest return for a
quarter was 23.4% (quarter ending December 31, 1998) and the lowest return for a
quarter was a loss of 11.6% (quarter ending September 30, 1998).

Fund with the S&P 500 Index and the  average  equity  income  fund  followed  by

<FN>

Past  performance  is no  guarantee  of future  returns.  Investment  return and
principal will fluctuate and an investor's shares,  when redeemed,  may be worth
more or less than their original cost.

The S&P 500 is the  Standard & Poor's  Composite  Index of 500 large  stocks,  a
widely recognized index of common stock prices. The Wilshire 5000 is a composite
index of more than 5,000 companies that includes  virtually all  publicly-traded
companies  that are suitable for  investment  by  institutional  investors.  For
comparative  purposes,  the Parnassus Equity Income Fund will henceforth use the
Wilshire  5000 instead of the S&P 500 because the former is more  representative
of the  market as a whole  while the S&P 500  emphasizes  larger  companies.  An
individual  cannot  invest in the S&P 500 Index or the  Wilshire  5000 Index and
these indices do not take any investing  expenses into account as do the figures
for The Parnassus Equity Income Fund and Lipper's Mid-Cap Value Average.

                                Fixed-Income Fund

Investment Objective and Principal Strategies

   The Parnassus  Fixed-Income Fund invests in a diversified  portfolio of bonds
and other fixed-income  instruments and its investment objective is a high level
of current income  consistent with safety and preservation of capital.  The Fund
invests in  investment  grade bonds  which means they are rated  within the four
highest  categories  as determined by a  nationally-recognized  rating  service.
Ordinarily,  at least 65% of the Fund's  total net assets  will be  invested  in
bonds  rated "A" or better by  Moody's  Investors  Service,  Inc.  (Moody's)  or
Standard & Poor's Rating Group (S&P).

   The Fund may  invest in a  combination  of  long-term,  intermediate-term  or
short-term  fixed-income  securities  depending on market  conditions  and these
securities may also have floating or variable  interest rates. The portfolio may
be comprised of U.S. Government  obligations,  corporate bonds, preferred stock,
convertible  preferred stock and convertible  bonds. The Fund will not invest in
"high-yield"  or "junk"  bonds.  The Fund may,  however,  hold  bonds  that were
investment  grade when  first  purchased,  but have  subsequently  fallen  below
investment  grade.  The Adviser,  however,  will not permit more than 15% of the
Fund's total net assets to be invested in such bonds at any one time.

   The Fund takes  social as well as  financial  factors  into account in making
investment  decisions.  In general,  The Parnassus  Fixed-Income  Fund looks for
companies  that  respect the  environment,  treat  their  employees  well,  have
effective equal employment  opportunity policies and good community relations as
well as ethical  business  dealings.  The Fund will not invest in companies that
are involved with gambling or manufacture alcohol or tobacco products.  The Fund
also screens out weapons  contractors and those that generate  electricity  from
nuclear power.

Principal Risks of Investing in the Fixed-Income Fund

   Investing  in the  Fund may  result  in a loss of  money  when you sell  your
shares. The Fund's share price changes daily based on the value of its holdings.
The Fund's average  weighted  maturity will be between 5 and 20 years. The value
of the Fund will vary  inversely  with  changes in interest  rates.  As interest
rates go up, the net asset  value will  likely go down,  and as  interest  rates
drop, the NAV of the Fund will likely go up. This Fund is intended for investors
who can accept the fact that there will be  principal  fluctuations.  The NAV of
the Fund  will  also be  affected  by other  factors  such as  credit  risk (the
possibility  that an issuer of a debt  obligation does not pay the Fund interest
or  principal)  and market  risk (the  possibility  that the market  value of an
investment  may move up or down  and that its  movement  may  occur  quickly  or
unpredictably). When you sell your shares of the Fund, they may be worth more or
less than what you paid for them.

                           California Tax-Exempt Fund

Investment Objective and Principal Strategies

   The Parnassus California Tax-Exempt Fund is available to California residents
only.  It invests in a diversified  portfolio of  tax-exempt,  investment  grade
securities  issued by California state and local governments and by other public
authorities.  Its  investment  objective  is to  provide a high level of current
income exempt from both federal and  California  personal  income tax consistent
with prudent investment management.

   The Fund invests in investment  grade bonds which means they are rated within
the four highest  categories  as determined  by a  nationally-recognized  rating
service.  No more than 20% of the Fund's  portfolio  will be invested in the 4th
highest category.  Under normal circumstances,  the Fund will invest 100% of its
assets in California municipal  obligations.  However, it could invest up to 20%
of its assets in  private  activity  bonds  that may be  subject to the  federal
alternative minimum tax.

   The Fund takes  social as well as  financial  factors  into account in making
investment decisions. The Parnassus California Tax-Exempt Fund seeks a portfolio
that will have a positive  social and  environmental  impact.  Examples would be
bonds that support schools, libraries, hospitals, mass transit, low and moderate
income housing and pollution control facilities.

Principal Risks of Investing in the California Tax-Exempt Fund

   Investing  in the  Fund may  result  in a loss of  money  when you sell  your
shares. The Fund's share price changes daily based on the value of its holdings.
The Fund's average  weighted  maturity will be 5 years or more. The value of the
Fund will vary  inversely with changes in interest  rates.  As interest rates go
up, the net asset value (NAV) will likely go down,  and as interest  rates drop,
the NAV of the Fund will  likely go up. The Fund also is subject to credit  risk
and market  risk.  This Fund is intended for  investors  who can accept the fact
that there will be  principal  fluctuations.  As the Fund  invests  primarily in
California municipal  securities,  there are special risks involved.  The NAV of
the Fund will be affected by factors  such as changes to the state  constitution
regarding taxes,  changes in the federal tax status of municipal  securities and
changes in bond  ratings  based on the  California  economy.  When you sell your
shares of the Fund, they may be worth more or less than what you paid for them.

</TABLE>

   The "Total Annual Trust Operating  Expenses" indicated in the table overstate
the expenses you would actually pay since they are based on expenses  before fee
reimbursements   and  not  on  the  Net  Expenses.   However,   the  Adviser  is
contractually  obligated to limit the total operating expenses to 1.07%,  0.87%,
and 0.75% of the net assets of the Equity Income Fund,  the  Fixed-Income  Fund,
and the California  Tax-Exempt  Fund,  respectively.  The Adviser's  contractual
obligation is in place until December 31, 2000, after which date the Adviser may
discontinue the expense limit upon giving 30 days' prior notice to the Fund. The
SEC,  though,  requires that the  calculations  of Total Annual Trust  Operating
Expenses be made on the basis of pre-waiver expenses to show what expenses might
potentially be in the future.

   The  Examples  in this table are  intended  to help you  compare  the cost of
investing in the Trust with the cost of investing  in other  mutual  funds.  The
Examples  assume  that you  invest  $10,000  in each of the  funds  for the time
periods  indicated  and  then  redeem  all of your  shares  at the end of  those
periods.  The Examples also assume that your  investments have a 5%* return each
year and that the  funds'  operating  expenses  remain the same.  Although  your
actual costs may be higher or lower, based on these assumptions, your cost would
be as follows:

   From time to time, a Fund may direct brokerage  commissions to firms that may
pay certain  expenses of a Fund subject to "best  execution."  This is done only
when brokerage  costs are reasonable and the Fund  determines that the reduction
of expenses is in the best interest of the Fund's shareholders.  No fund engaged
in such  directed  brokerage  in 1998.  If a fund  does so in the  future,  such
directed  brokerage is expected to occur on an irregular basis, so the effect on
the expense ratios cannot be calculated with any degree of certainty.

THE LEGEND OF MT. PARNASSUS
- --------------------------------------------------------------------------------
   Parnassus  is a mountain  in central  Greece  whose twin peaks rise more than
8,000 feet above sea level.  A dense forest covers the slopes of Mt.  Parnassus,
but the summit is rocky and, most of the time,  covered with snow.  The mountain
plays a  prominent  role in  Greek  mythology  because  on its  southern  slope,
overlooking the Gulf of Corinth, lies Delphi, site of the famous oracle.

   Originally,  the oracle  belonged to Gaia, the earth goddess.  Later,  Mother
Earth was worshipped under the name Delphyne and she controlled the oracle along
with her serpent-son,  Python,  and her  priestess-daughters  who controlled the
rites.  Eventually,  the Greek god, Apollo,  took over the site, doing away with
Python, but keeping the priestesses.

   The  most  "Greek"  of  the  gods,  Apollo   represented   enlightenment  and
civilization and presided over the establishment of cities.  Identified with the
development  of Greek codes of law,  Apollo was also the god of light,  a master
musician and a skilled archer.  Legend has it that Python,  an enormous  serpent
raised  in the  caves of Mt.  Parnassus,  controlled  the site of  Delphi.  When
Apollo,  representing  civilization,  challenged Python,  representing  anarchy,
there was a heroic struggle, but the god finally killed the dragon by shooting a
hundred arrows into its body.

   There  were  many  oracles  in  ancient  Greece,  but only the one at  Delphi
achieved  a record of  reliability.  Apollo's  temple at Delphi  soon  became an
enormous  storehouse of treasures that were gifts of those who had consulted the
oracle.

   The oracle communicated through the voice of a priestess who spoke while in a
trance.  The priests of Delphi,  who  interpreted  the sayings of the priestess,
obtained a great deal of knowledge  and  information  from talking to the people
who came from all over the Greek world to consult at the shrine of Apollo. Quite
often, the oracle went against the prevailing wisdom of the time and frequently,
the proud were humbled and the lowly were justified.

INVESTMENT OBJECTIVES AND POLICIES
- --------------------------------------------------------------------------------

Social Policy

   The Adviser looks for certain  social  policies in the companies in which the
Trust invests.  These social policies are: (1) treating  employees  fairly;  (2)
sound environmental protection policies; (3) a good equal employment opportunity
program;  (4) quality products and services;  (5) a record of civic  commitment;
and (6) ethical business practices. Obviously, no company will be perfect in all
categories,  but the Adviser makes value  judgments in deciding which  companies
best meet the criteria.  The Adviser also  considers  social  factors other than
these six (as  discussed  under the  investment  objectives of each of the three
Funds).

   Although the Trust  emphasizes  positive  reasons for investing in a company,
our operating policies call for excluding  companies that manufacture alcohol or
tobacco  products or are  involved  with  gambling.  The Trust also  screens out
weapons contractors and those that generate electricity from nuclear power.

   The social criteria of The Parnassus  Income Trust limit the  availability of
investment  opportunities.  However,  the Trustees and the Adviser  believe that
there are  sufficient  investments  available  that can meet the Trust's  social
criteria and still enable each fund to provide a competitive rate of return.

                               Equity Income Fund

   The investment objective of the Equity Income Fund is both current income and
capital  appreciation.  The Fund tries to achieve  this  objective  by investing
primarily in a diversified  portfolio of equity  securities.  Equity  securities
include common and preferred  stock as well as securities  that are  convertible
into these  instruments such as convertible  bonds. As an operating  policy,  at
least 75% of the  Fund's  total  assets  will  normally  be  invested  in equity
securities  that pay a dividend  (or  interest in the case of  convertible  debt
instruments),  and up to 25% of the  Fund's  total  assets  may be  invested  in
non-dividend paying equity securities, in investment grade debt securities or in
money market instruments.  However, for temporary,  defensive purposes, the Fund
may invest all its assets in money market  instruments or investment grade debt.
"Investment  grade" means rated within the four highest categories as determined
by a nationally-recognized rating service such as S&P or Moody's.

   The  Fund  seeks to  invest  in  equity  securities  that  pay  above-average
dividends and which the Adviser believes have the capacity to raise dividends in
the future and also have the potential for capital appreciation.  The Fund seeks
to achieve a yield for its shareholders that exceeds the yield on the securities
comprising  the S&P 500  Composite  Stock Price Index.  Issuers of securities in
which the Fund invests must meet the social criteria stated in this Prospectus.

   The Equity Income Fund may, as an operating policy,  also invest up to 10% of
its assets in  community  development  loan  funds  such as those  that  provide
financing for small business and for low and moderate income  housing.  The Fund
will not make loans to a project  itself,  but rather  will  invest  money in an
intermediary community loan fund. With projects having a strong, positive social
impact,  the Fund may invest in  obligations  issued by community  loan funds at
below market interest rates.  Generally,  there is no secondary market, and thus
no liquidity,  for these  investments.  In general,  the Fund seeks to invest in
community  organizations that have had a successful record in making these kinds
of loans and that are deemed creditworthy by the Adviser.

Risk Factors

   As with all investments,  there are a number of risk factors  associated with
the Equity  Income Fund.  Equity  securities  in the Fund pose a risk in that an
individual  enterprise  may fall on hard  times and  operate  with  little or no
profits;  this would depress the price of its stock.  Also,  companies  that pay
dividends may not do so if they don't have profits or adequate cash flow.  There
are also risks associated with the economic cycle (e.g., a recession) as well as
market risks that might sharply  reduce the valuation of all stocks or stocks in
a specific  industry.  Since the Equity Income Fund invests  primarily in stocks
that pay a dividend,  the  portfolio  will be  invested  in larger,  more mature
companies.  These  companies  tend to be safer  and  less  volatile  than  those
companies that don't pay a dividend.

   With preferred stock and higher-yielding  common stocks such as utilities,  a
major risk is increased  interest  rates that will  decrease the market value of
the securities in question.  For a fuller description of interest rate risk, see
the Risk Factors section under Fixed-Income Fund.

   Money market instruments  generally limit potential for capital appreciation.
The Fund's investment in debt securities and money market  instruments  subjects
it to other types of risks.  For more  information on the risks  associated with
debt securities, see the Risk Factors section under Fixed-Income Fund.

   There are also special risks involved with community development  investments
which may  comprise as much as 10% of the Fund.  These  investments  do not have
liquidity,  and  community  loan  funds do not have the same  kind of  financial
resources as do large  commercial  enterprises.  Moreover,  there is no publicly
available  track  record  for  community  loan funds so it is hard to assess the
history of these kinds of investments.  In fact, one of the social objectives of
The Parnassus Income Trust is to establish a publicly available track record for
community development investments.

<PAGE>



                                Fixed-Income Fund

   The investment  objective of the Fixed-Income Fund is a high level of current
income consistent with safety and preservation of capital.  The Adviser seeks to
achieve this  objective by  investing  in a  diversified  portfolio of bonds and
other  fixed-income  instruments that are rated investment grade.  Securities in
the lowest of the four  investment  grade  categories  (Baa or BBB,  as rated by
Moody's and S&P,  respectively)  are considered  investment  grade, but they may
have speculative elements about them. The Fixed-Income Fund ordinarily will have
at least 65% of its net  assets in  securities  rated "A" or better  (i.e.,  the
three highest  categories) by S&P or Moody's.  See the Appendix in the SAI for a
description  of bond  ratings.  Obligations  issued or  guaranteed by the United
States Government, its agencies or instrumentalities need not have a rating.

   The  Fixed-Income  Fund  may  invest  in  long-term,   intermediate-term   or
short-term  fixed-income  securities or any  combination  thereof,  depending on
market  conditions,  and these  securities  may also have  floating  or variable
interest rates. Securities in this Fund may include preferred stock, convertible
preferred stock and convertible bonds.

   The Fixed-Income Fund invests only in investment grade  securities.  The Fund
will not invest in  "high-yield"  or "junk"  bonds.  Because of this emphasis on
quality and safety,  the Fund's yield may not be as high as it  otherwise  might
be.

   This Fund may, as an operating policy, also invest up to 10% of its assets in
community  development loan funds. See the section on the Equity Income Fund for
details.

Risk Factors

   The Fund's  holdings,  share price,  yield and total return may  fluctuate in
response to bond market movements. The Adviser anticipates that the Fixed-Income
Fund's average weighted maturity will be between 5 and 20 years. Because of this
relatively  long  maturity,  the value of this Fund  will  vary  inversely  with
changes in interest rates. As interest rates go up, the NAV will likely go down,
and as  interest  rates  drop,  the NAV of this Fund will  likely go up. This is
known as "interest rate risk." The Fund is subject to credit risk (the risk that
the default of an issuer would leave the Fund with unpaid interest or principal)
and market risk (the risk that the market value of an investment  may move up or
down, sometimes rapidly or unpredictably). The Fixed-Income Fund is intended for
investors who can accept the fact that there will be principal fluctuations. For
a description of risks associated with community development loan funds, see the
Risk Factors section in Equity Income Fund.

<PAGE>



                           California Tax-Exempt Fund

   The investment  objective of the California  Tax-Exempt  Fund is to provide a
high level of current  income exempt from both federal and  California  personal
income tax consistent with prudent  investment  management.  The Adviser pursues
this objective by investing in a diversified portfolio of tax-exempt, investment
grade securities  issued by California state and local  governments and by other
public authorities. This Fund is for California residents only.

   For  temporary  purposes,  the Fund may  invest  up to 10% of its  assets  in
no-load,  open-end  investment  companies which invest in tax-exempt  securities
with maturities of less than one year ("tax-exempt  money market funds") but the
Fund will put no more than 5% of its assets into any one fund.

   Normally,   the  Fund  will  have  all  its  assets  invested  in  tax-exempt
securities,  but may  temporarily  invest in  short-term  taxable  money  market
instruments.  Temporary  investments  will be limited to  obligations  issued or
guaranteed by the United States Government,  its agencies or  instrumentalities,
prime   commercial   paper  or   deposits   with   federally-insured   financial
institutions,  and the Fund may engage in repurchase transactions involving U.S.
Government securities.

Risk Factors

   Since  the  California   Tax-Exempt  Fund  invests  primarily  in  California
municipal  securities,  there are special risks  involved.  Changes in the State
constitution  and other  laws  raise  questions  about the  ability of State and
municipal issuers to obtain sufficient revenue to pay their bond obligations. In
particular, California voters have approved amendments to the State constitution
which limit  property  taxes as well as the ability of taxing  entities to raise
other types of taxes. In addition,  another constitutional amendment,  popularly
known  as the Gann  Initiative,  limits  increases  in  revenue  appropriations.
Federal  legislative  proposals have threatened the tax-exempt  status or use of
mu-nicipal  securities.  Because the Fund will  concentrate  its  investments in
California obligations,  the Fund is more susceptible to economic, political and
other  developments that may adversely affect issuers of California  obligations
than a municipal bond fund that is not as geographically concentrated. By way of
illustration,   although  California  has  a  relatively   diversified  economy,
California has concentrations in the computer services,  software design, motion
pictures and high technology manufacturing industries.  The Fund, therefore, may
be more susceptible to developments  affecting those industries than a municipal
bond fund that invests in obligations of several states.

   The Fund  typically  invests in securities  with  maturities of more than one
year, and the average  maturity of all securities  will usually be five years or
more. If the Adviser determines that market conditions warrant a shorter average
maturity,  the Fund will be adjusted accordingly.  The Fund is subject to credit
risk, market risk and interest rate risk (for a full description of these risks,
see Risk Factors in Fixed-Income Fund). In addition,  the Fund's investments may
be difficult to value  precisely  and sell at a desired time or price.  Also the
Fund may be affected if a  municipality  fails to include an obligation  held by
the Fund in future  budgets.  The  California  Tax-Exempt  Fund is intended  for
investors who can accept the fact that there will be principal fluctuations.

THE ADVISER

- --------------------------------------------------------------------------------
   Parnassus  Investments (the "Adviser"),  One Market-Steuart  Tower #1600, San
Francisco,  California 94105 acts as investment  adviser to each fund subject to
the  control of the  Trust's  Board of  Trustees,  and as such,  supervises  and
arranges the purchase and sale of securities held in the funds' portfolios.  The
Adviser has been the investment manager of The Parnassus Fund since 1985 and The
Parnassus Income Trust since 1992.

   For its services,  the Trust,  under an Investment  Advisory  Agreement  (the
"Agreement") between the Trust and the Adviser, pays the Adviser a fee, computed
and payable at the end of each month,  at the following  annual  percentages  of
each Fund's average daily net assets:  for the Equity Income Fund,  0.75% of the
first $30  million,  0.70% of the next $70 million and 0.65% of the amount above
$100 million; and for the Fixed-Income Fund and the California  Tax-Exempt Fund,
the fee is 0.50% of the first $200  million,  0.45% of the next $200 million and
0.40% of the amount above $400 million.  However,  after taking into account the
Adviser's expense  reimbursement (more fully described below) the following were
actually  charged in 1999. For the Equity Income Fund,  the investment  advisory
fee was  0.53%.  Parnassus  Investments  received  net  advisory  fees  totaling
$229,333 from the Equity Income Fund for the year ended  December 31, 1999.  For
the  Fixed-Income  Fund,  the  investment  advisory  fee  was  0.14%.  Parnassus
Investments  received net advisory fees totaling  $16,392 from the  Fixed-Income
Fund for the year ended December 31, 1999. For the California  Tax-Exempt  Fund,
the  investment  advisory  fee was 0.25%.  Parnassus  Investments  received  net
advisory fees totaling $18,927 from the California  Tax-Exempt Fund for the year
ended December 31, 1999.

   Parnassus Investments has agreed to reduce its investment advisory fee to the
extent  necessary to limit total  operating  expenses to 1.07% of net assets for
the Equity Income Fund, 0.87% of net assets for the Fixed-Income Fund, and 0.75%
of net assets for the California Tax-Exempt Fund.

HOW TO PURCHASE SHARES
- --------------------------------------------------------------------------------

Direct Purchase Of Shares

   To purchase shares, an investor should complete and mail the application form
along with a check payable to The Parnassus  Income Trust.  It should be sent to
the Trust at the following address.

                                    The Parnassus Income Trust
                                    One Market-Steuart Tower #1600
                                    San Francisco, California 94105

   An initial  investment  must be at least  $2,000 per fund  except for certain
employee benefit plans or tax qualified retirement plans (such as IRAs or SEPs),
Parnassus  Automatic  Investment Plan (PAIP) and accounts opened pursuant to the
Uniform  Gifts to Minors  Act  ("UGMA")  or  Uniform  Transfers  to  Minors  Act
("UTMA"),  which have a $500 minimum.  Additional  investments  for all accounts
must be at least $50.  Parnassus  Investments  reserves  the right to reject any
order.  With  additional  investments,  shareholders  should  write the name and
number of the account on the check. Checks do not need to be certified,  but are
accepted  subject to collection  and must be drawn in United  States  dollars on
United States banks.  Investments  in the Equity Income Fund and the  California
Tax-Exempt  Fund,  if received  before 1:00 p.m.  San  Francisco  time,  will be
processed at the net asset value  calculated  on the same  business day they are
received.  If an investment in either of these Funds is received after 1:00 p.m.
San Francisco  time, it will be processed the next business day. A fee of $15.00
will be assessed if a check is returned to us unpaid due to insufficient  funds,
stop payment or for any other reason.

   An investment  in the  Fixed-Income  Fund, if received  before 12:00 noon San
Francisco time, will be processed at the net asset value  calculated on the same
business day it is received.  An investment  in this Fund  received  after 12:00
noon San Francisco time will be processed on the next business day.

Other Information

   The Trust also offers  additional  services to investors  including plans for
the  systematic  investment and withdrawal of money as well as IRA, ROTH IRA and
SEP  plans.   Information   about  these  plans  is  available   from  Parnassus
Investments.

   There is no sales charge for the purchase of Trust shares,  but investors may
be  charged  a  transaction  or  other  fee  in  connection  with  purchases  or
redemptions  of Trust  shares  on  their  behalf  by an  investment  adviser,  a
brokerage firm or other financial institution.

Purchases Via Parnassus Automatic Investment Plan (PAIP)

   After making an initial  investment to open a Fund account ($500 minimum),  a
shareholder may purchase additional Fund shares ($50 minimum) via the PAIP. On a
monthly or quarterly  basis,  your money will  automatically be transferred from
your bank  account to your fund  account on the day of your  choice (3rd or 18th
day of the month).  You can elect this option by filling out the PAIP section on
the new account form.  For further  information,  call the Trust and ask for the
free brochure called "Automatic  Investing and Dollar-Cost  Averaging." A fee of
$15.00  will be  assessed  if the  automatic  purchase  cannot  be  made  due to
insufficient funds, stop payment or for any other reason.

Net Asset Value

   The net asset value (NAV) for each fund will usually be  calculated  on every
day the New York Stock Exchange (NYSE) is open for trading  ("business day") and
on any other day there is a sufficient  degree of trading in investments held by
the Fund to affect the net asset value. The NYSE is closed on national  holidays
and Good Friday. The NAV of the Equity Income Fund and the California Tax-Exempt
Fund will usually be calculated as of the close of trading on the NYSE,  usually
4:00  p.m.  Eastern  time.  The NAV of the  Fixed-Income  Fund will  usually  be
determined  as of one hour prior to the close of  trading  on the NYSE,  usually
3:00 p.m.  Eastern time. The NAV may not be determined on any day that there are
no transactions in shares of the Fund.

   The net  asset  value per  share is the  value of a fund's  assets,  less its
liabilities,  divided  by the  number of  outstanding  shares of that  fund.  In
general,  the value of a fund's portfolio securities is the market value of such
securities. However, securities and other assets for which market quotations are
not readily available are valued at their fair value as determined in good faith
by the Adviser under procedures established by and under the general supervision
and responsibility of the Trust's Board of Trustees.

HOW TO REDEEM SHARES
- --------------------------------------------------------------------------------
   You may sell or redeem  your  shares by  offering  them for  "repurchase"  or
"redemption"  directly to the Trust.  To sell your shares to the Trust (that is,
to redeem your shares),  you must send your written instructions to the Trust at
One  Market-Steuart  Tower #1600, San Francisco,  California 94105. You may also
send your redemption  instructions by FAX to (415) 778-0228 if the redemption is
less than $25,000. Your shares will be redeemed at the NAV next determined after
receipt by the Trust of your  written  instructions  in proper  form.  Give your
account number and indicate the number of shares you wish to redeem.  All owners
of the account  must sign unless the  account  application  states that only one
signature is necessary for  redemptions.  All redemption  checks must be sent to
the address of record on the account. The Trust must have a change-of-address on
file for 30 days before we send  redemption  or  distribution  checks to the new
address.  Otherwise,  we require a signature guarantee or the check must be sent
to the old address.  If you wish to have the  redemption  proceeds  sent by wire
transfer or by overnight  mail,  there will be a charge of $10 per  transaction.
The Trust usually  requires  additional  documents when shares are registered in
the name of a  corporation,  agent or fiduciary or if you are a surviving  joint
owner. In the case of a corporation,  we usually require a corporate  resolution
signed  by the  secretary.  In the  case of an agent or  fiduciary,  we  usually
require an  authorizing  document.  In the case of a surviving  joint owner,  we
usually require a copy of the death  certificate.  Contact the Trust by phone at
(800) 999-3505 if you have any questions about  requirements  for redeeming your
shares.

   If the Trust has  received  payment for the shares you wish to redeem and you
have provided the  instructions  and any other documents needed in correct form,
the  Trust  will  promptly  send you a check  for the  proceeds  from the  sale.
Ordinarily, the Trust must send you a check within seven days unless the NYSE is
closed for days other than weekends or holidays. However, payment may be delayed
for any shares  purchased by check for a reasonable  time (not to exceed 15 days
from the date of such  purchase)  necessary for the Trust to determine  that the
purchase check will be honored.

                                       17

   Exchange Privileges.  The proceeds of a redemption of shares of a fund can be
used to purchase  shares of another fund. The proceeds of a redemption of shares
from a fund can also be used to purchase  shares of The Parnassus  Fund, but the
purchase of Parnassus  Fund shares will be subject to a sales charge if no sales
charge was paid on the fund shares  redeemed.  If shares are  redeemed  from The
Parnassus Fund and the proceeds  invested in shares of the Trust,  there will be
no  additional  sales charge if those Trust shares are redeemed and the proceeds
invested back into The Parnassus Fund.

   There is no limit on the  number or dollar  amount  of  exchanges.  The Trust
reserves the right to modify or eliminate this exchange privilege in the future.
The  exchange  privilege  is only  available in states where the exchange may be
legally  made.  The  exchange  of shares is treated as a sale and an  exchanging
shareholder may, therefore, realize a taxable gain or loss.

   Telephone  Transfers.  Shareholders  who  elect  to  use  telephone  transfer
privileges  must so indicate  on the account  application  form.  The  telephone
transfer  privilege allows a shareholder to effect exchanges from a fund into an
identically  registered  account in another fund or The Parnassus Fund.  Neither
the Trust nor Parnassus  Investments  will be liable for following  instructions
communicated  by  telephone  reasonably  believed to be  genuine;  a loss to the
shareholder  may result due to an  unauthorized  transaction.  The Trust and the
transfer agent will employ  reasonable  pro-cedures to confirm that instructions
communicated by telephone are genuine.

   Procedures may include one or more of the following:  recording all telephone
calls requesting telephone exchanges, verifying authorization and requiring some
form of personal  identification prior to acting upon instructions and sending a
statement  each time a  telephone  exchange  is made.  The  Trust and  Parnassus
Investments  may be liable  for any  losses due to  unauthorized  or  fraudulent
instructions  only if such  reasonable  procedures are not followed.  Of course,
shareholders are not obligated in any way to authorize  telephone  transfers and
may choose to make all exchanges in writing.  The telephone  exchange  privilege
may be modified or  discontinued  by the Trust at any time upon 60 days' written
notice to shareholders.

   Redemption  of Small  Accounts.  The  Trustees  may,  in order to reduce  the
expenses of the Trust, redeem all of the shares of any shareholder whose account
is worth less than $500 (as a result of a redemption  order).  This will be done
at the NAV  determined as of the close of business on the business day preceding
the sending of such notice of redemption. The Trust will give shareholders whose
shares are being  redeemed  60 days' prior  written  notice in which to purchase
sufficient shares to avoid such redemption.

DIVIDENDS AND TAXES
- -------------------------------------------------------------------------------
   The  Equity  Income  Fund  normally  declares  and  pays  dividends  from net
investment  income ("income  dividends") on a quarterly  basis. The Fixed-Income
Fund  and the  California  Tax-Exempt  Fund  normally  declare  and  pay  income
dividends  on a  monthly  basis.  Dividends  from net  long-term  capital  gains
("capital gains  dividends") are paid once a year (usually in December) for each
Fund.  Shareholders can have dividends paid in additional  shares and reinvested
or paid out in cash.  If an investor  purchases  shares just before the dividend
date, he or she will be taxed on the  distribution  even though it's a return of
capital.

Taxation of Shareholders in Equity Income and Fixed-Income Funds

   For the Equity Income Fund and the Fixed-Income  Fund, all dividends from net
investment  income  together  with  distributions  of  short-term  capital gains
(collectively,  "income  dividends")  will be  taxable  as  ordinary  income  to
shareholders  even though paid in additional  shares.  Any net long-term capital
gains ("capital gain distributions")  distributed to shareholders are taxable as
such.  An exchange of a fund's shares for shares of another fund will be treated
as a sale of a fund's  shares for tax purposes  and any gain on the  transaction
may be subject to state and federal  income  tax.  Tax-exempt  and  tax-deferred
shareholders, of course, will not be required to pay taxes on any dividends paid
to them.  Holders of IRAs and other  tax-deferred  retirement  accounts  are not
required to pay taxes until distribution.  (Tax-exempt  retirement accounts,  of
course, never have to pay taxes.)

   For  shareholders of these funds,  the Trust may be required to impose backup
withholding  at a rate  of  31%  from  any  income  dividend  and  capital  gain
distribution.  Shareholders can eliminate any backup withholding requirements by
furnishing  certification of U.S. taxpayer  identification numbers and reporting
dividends.

   To the extent that income  dividends  are derived from  qualifying  dividends
paid by domestic  corporations whose shares are owned by a fund, such dividends,
in the hands of that fund's corporate shareholders, will be eligible for the 70%
dividends   received   deduction.   Individuals   do  not   qualify   for   this
deduction--only corporations.

Taxation of Shareholders of California Tax-Exempt Fund

   This Fund is for California  residents only.  Dividends derived from interest
on state and local obligations constitute  "exempt-interest"  dividends on which
shareholders  are not  subject to federal  income tax. To the extent that income
dividends are derived from earnings  attributable to California  state and local
obligations,  they will be exempt from federal and  California  personal  income
tax. Such dividends may be subject to California  franchise  taxes and corporate
income taxes if received by a corporation subject to such taxes.

   Dividends  attributable to interest on certain private  activity bonds issued
after August 7, 1986,  must be included in federal  alternative  minimum taxable
income for the purpose of  determining  liability  (if any) for the  alternative
minimum tax (AMT) for individuals and for corporations.

   Dividends  derived from taxable interest and any  distributions of short-term
capital gains are taxable to shareholders as ordinary  income.  Distributions of
net long-term  capital gains, if any, are taxable to shareholders as a long-term
capital  gain  regardless  of how long  their  shares of the Fund have been held
except that  losses on certain  shares held less than six months will be treated
as long-term capital losses to the extent of the capital gain dividends received
on such shares.

   The  Fund  will  notify  shareholders  each  January  as to the  federal  and
California tax status of dividends paid during the previous calendar year.

                       Investment Objectives and Policies

     The goal of the Trust is to provide  shareholders  with  current  income by
investing in securities that have a positive impact on society. The Trust, which
is an open-end,  management  investment  company,  offers  investors a choice of
three funds:  the Equity Income Fund, the  Fixed-Income  Fund and the California
Tax-Exempt Fund. The Trust's Prospectus  describes the investment  objective and
principal strategies of each fund.

Investment Restrictions

     The Trust has  adopted the  following  restrictions  (in  addition to those
indicated in the Prospectus) as fundamental policies which may not be changed as
to a fund without the approval of the holders of a "majority" (as defined in the
Investment  Company  Act of 1940 (the  "1940  Act") of that  fund's  outstanding
shares.  A vote of the  holders  of a  "majority"  (as so  defined)  of a fund's
outstanding  shares  means a vote of the  holders  of the lesser of (i) 67% of a
fund's shares  present or  represented  by proxy at a meeting at which more than
50% of the  outstanding  shares  are  represented  or (ii)  more than 50% of the
outstanding shares.

The Trust may not:

         (1)      With respect to 75% of a fund's total net assets, purchase the
                  securities  of any one issuer  other than  obligations  of the
                  U.S. Government,  its agencies or  instrumentalities,  if as a
                  result:  (i) more than 5% of a fund's total net assets  (taken
                  at current  value) would then be invested in  securities  of a
                  single  issuer or (ii) a fund  would hold more than 10% of the
                  outstanding voting securities of any one issuer.

         (2)      Purchase any security if as a result any fund would have 25%
                  or more of its net assets (at current value) would be
                  invested in a single industry.

         (3)      Purchase securities on margin (but the Trust may obtain such
                  short-term credits as may be necessary for the
                  clearance of transactions).

         (4)      Make short sales of securities, purchase on margin or purchase
                  puts, calls, straddles or spreads.

         (5)      Issue  senior  securities,  borrow  money or pledge its assets
                  except that each fund may borrow from a bank for  temporary or
                  emergency  purposes in amounts not exceeding 10% (taken at the
                  lower  of cost  or  current  value)  of its  net  assets  (not
                  including the amount borrowed) and pledge its assets to secure
                  such  borrowings.  A fund will not make  additional  purchases
                  while any borrowings are outstanding.

         (6)      Buy or  sell  commodities  or  commodity  contracts  including
                  futures   contracts  or  real  estate,   real  estate  limited
                  partnerships or other interests in real estate although it may
                  purchase and sell securities of companies which invest or deal
                  in real estate.

         (7)      Act as  underwriter  except to the extent  that in  connection
                  with the disposition of portfolio securities, it may be deemed
                  to be an underwriter under certain federal securities laws.

         (8)      Participate on a joint (or joint and several) basis in any
                  trading account in securities.

         (9)      Invest in securities of other registered investment companies
                  except that each fund may invest up to 10% of its assets in
                  money market funds, but no more than 5% of its assets in any
                  one fund and no Fund may own more than 3% of  the outstanding
                  voting shares of any one fund. This

                                                                      B-2


                  restriction,  however, does not apply to a transaction that is
                  a part of a merger, consolidation or other acquisition.

         (10)     Invest in interests in oil, gas or other  mineral  exploration
                  or development programs or in oil, gas or other mineral leases
                  although it may invest in the common stocks of companies which
                  invest in or sponsor such programs.

(11)              Make loans except through repurchase agreements;  however, the
                  Trust may engage in  securities  lending and may also  acquire
                  debt  securities  and other  obligations  consistent  with the
                  applicable  fund's  investment   objective(s)  and  its  other
                  investment  policies  and  restrictions.  Investing  in a debt
                  instrument  that is convertible  into equity or investing in a
                  community loan fund is not considered the making of a loan.

Other Policies

     As an  operating  policy,  the  Equity  Income  Fund may  purchase  foreign
securities up to a maximum of 15% of the value of its total net assets,  but the
Fixed-Income   and  California   Tax-Exempt   Funds  may  not  purchase  foreign
securities.  Such  investments  increase a portfolio's  diversification  and may
enhance  return,  but they also involve  some special  risks such as exposure to
potentially adverse local political and economic  developments;  nationalization
and  exchange  controls;  potentially  lower  liquidity  and higher  volatility;
possible  problems  arising  from  accounting,   disclosure,   settlement,   and
regulatory  practices  that  differ  from U.S.  standards;  and the chance  that
fluctuations  in foreign  exchange  rates will decrease the  investment's  value
(favorable change can increase its value).

     Under  normal  circumstances,  each fund of the Trust  will have its assets
invested according to its stated investment  objective.  However,  for temporary
defensive  purposes or pending the  investment  of the proceeds of sales of fund
shares or portfolio  securities,  all or part of a fund's assets may be invested
in money market instruments or in repurchase agreements.  In these situations, a
fund will not be following its investment objective.

     An operating  (although not fundamental) policy of the Trust is that it may
not make an  investment  if,  thereafter,  more than 15% of a fund's  net assets
would be illiquid.  If the Trust finds itself with more than 15% of a fund's net
assets so  invested,  it will take action to bring that fund's  illiquid  assets
below 15%. Illiquid assets include: (i) those which are restricted,  i.e., those
which cannot be freely sold for legal reasons;  (ii) fixed time deposits subject
to withdrawal  penalties (other than overnight time deposits);  (iii) repurchase
agreements  having a maturity of more than seven days; and (iv)  investments for
which market quotations are not readily available.  However,  the 15% limit does
not include  obligations  which are  payable at  principal  amount plus  accrued
interest  within  seven days after  purchase or  commercial  paper  issued under
section  4 (2)  of the  Securities  Act of  1933,  as  amended  (1933  Act),  or
securities  eligible  for resale  under Rule 144A of the 1933 Act that have been
determined to be liquid pursuant to procedures adopted by the Board of Trustees.

Operating Policies

     The Trust has adopted the following operating policies which may be changed
by a vote of the majority of the Fund's Trustees:

       (1)  The Equity  Income Fund may purchase  warrants up to a maximum of 5%
            of the value of its  total  net  assets,  but the  Fixed-Income  and
            California Tax-Exempt Funds may not purchase warrants.

(2)      No fund may hold or purchase foreign currency except the Equity Income
         Fund to the extent necessary to settle foreign securities transactions.
                                       B-3

Repurchase Agreements

     The Trust may  purchase  the  following  securities  subject to  repurchase
agreements: certificates of deposit, certain bankers' acceptances and securities
which are direct  obligations of, or that are fully  guaranteed as to principal,
by the United States or any agency or  instrumentality  of the United States.  A
repurchase  transaction  occurs when at the time the Trust purchases a security,
the Trust  also  resells  it to the  vendor  (normally  a  commercial  bank or a
broker-dealer) and must deliver the security (and/or securities  substituted for
them under the repurchase agreement) to the vendor on an agreed-upon date in the
future. Such securities,  including any securities so substituted,  are referred
to as the "Resold Securities." The Adviser will consider the creditworthiness of
any vendor of repurchase  agreements and continuously  monitor the collateral so
that it never falls below the resale price. The resale price is in excess of the
purchase price in that it reflects an agreed-upon market interest rate effective
for the period of time during which the Trust's  money is invested in the Resold
Securities.  The  majority  of  these  transactions  run from day to day and the
delivery  pursuant to the resale typically will occur within one to five days of
the  purchase.  A fund's risk is limited to the ability of the vendor to pay the
agreed-upon sum upon the delivery date.

      If there is a default,  the Resold Securities  constitute security for the
repurchase obligation and will be promptly sold by the Trust. However, there may
be delays and costs in establishing the Trust's rights to the collateral and the
value of the  collateral  may decline.  A fund will bear the risk of loss in the
event that the other party to the transaction defaults on its obligation and the
fund is  delayed  or  prevented  from  exercising  its right to  dispose  of the
underlying securities,  including the risk of a possible decline in the value of
the  underlying  securities  during the period in which the fund seeks to assert
its rights.

     Repurchase  agreements can be considered as loans  "collateralized"  by the
Resold  Securities  (such  agreements being defined as "loans" in the 1940 Act.)
The  return  on  such  "collateral"  may be  more or less  than  that  from  the
repurchase  agreement.  The  Resold  Securities  will be marked to market  every
business  day so that the  value of the  "collateral"  is at least  equal to the
value of the loan  including the accrued  interest  earned  thereon.  All Resold
Securities  will be held by the Trust's  custodian  either directly or through a
securities depository.

Lending Portfolio Securities

     To generate additional income, a fund may lend its portfolio  securities to
broker-dealers,  banks or other  institutional  borrowers of securities.  A fund
must receive  collateral  in the form of cash or U.S.  Government  securities at
least equal to 102% of the value of the securities loaned.  This collateral will
be valued daily. Should the market value of the loaned securities increase,  the
borrower  must  furnish  additional  collateral  to that  fund.  During the time
portfolio  securities  are on loan, the borrower pays that fund any dividends or
interest  received on such  securities.  While a fund does not have the right to
vote  securities  that are on loan, a fund may terminate the loan and regain the
right to vote if that is considered  important  with respect to the  investment.
The  borrower  can repay the loan at any time and the  lending  fund can  demand
repayment at any time.

Other Policies and Risks of the California Tax-Exempt Fund

     The  two  principal   classifications   of  municipal  bonds  are  "general
obligation"  and "revenue"  bonds.  General  obligation  bonds are backed by the
taxing power of the issuer and  considered  the safest type of  municipal  bond.
Revenue  bonds are  backed by the  revenue  from a specific  project  and may be
backed by the credit and  security  of a private  user.  Investments  in revenue
bonds have more potential risk. While interest on private activity revenue bonds
may be  tax-exempt,  it may be treated as a tax  preference  item for  taxpayers
subject to the federal alternative  minimum tax. The California  Tax-Exempt Fund
will minimize its  investment in such bonds,  and no more than 20% of the Fund's
assets will be invested  in bonds  whose  income is treated as a tax  preference
item under the federal alternative minimum tax.

                                       B-4

     The Fund may also purchase a right to sell a security held by the Fund back
to the issuer of the  security  or another  party at an agreed upon price at any
time during a stated period or on a certain  date.  These rights are referred to
as "demand  features" or "puts." The Fund may also purchase floating or variable
rate  obligations  (including  participations)  as well as variable  rate demand
notes (VRDNs) which feature  interest rates that float with an index and a "put"
feature.

     The Fund will hold only investment grade securities,  i.e., those that have
been rated at the time of  purchase  in one of the four  highest  categories  by
Moody's  Investors  Service,  Inc.  (Moody's),  Standard & Poor's  Ratings Group
("Standard  &  Poor's")  or Fitch  Investors  Services,  Inc.  ("Fitch"),  or if
unrated,  being similar in quality,  in the Adviser's opinion,  to securities in
one  of the  top  four  categories.  These  are  considered  "investment  grade"
securities, although, according to Moody's, bonds in the fourth-highest category
("Baa")  are  regarded  as having an  adequate  capacity  to pay  principal  and
interest,  but with greater  vulnerability to adverse economic conditions;  they
also have some speculative  characteristics.  (An Appendix to the SAI contains a
description  of the ratings of Moody's,  Fitch and  Standard & Poor's.) The Fund
will not invest  more than 20% of its total  assets in  securities  rated in the
fourth  highest  category.  If the rating on a  security  held by the Fund falls
below investment  grade after purchase,  the Adviser will consider such an event
in its  evaluation of the  security,  but it will not  necessarily  result in an
automatic  sale of that  security.  The Fund does,  however,  have an  operating
policy that no more than 5% of its assets may consist of  securities  which were
rated  investment  grade at the time of purchase,  but  subsequently  drop below
investment  grade.  Because the Fund emphasizes safety and avoids junk bonds and
other  securities  below  investment  grade,  the yield may not be as high as it
otherwise might be.

     Examples of activities  which the Trustees have  determined have a positive
social and  environmental  impact  include  financing  for  schools,  libraries,
hospitals,  mass transit,  low and moderate  income housing,  pollution  control
facilities,  renewable energy  resources,  energy  conservation  projects,  park
development  and open space  acquisition.  The Fund will not finance  activities
with a negative social or environmental impact as determined by the Trustees and
the Adviser.  Examples of  activities  with a negative  social or  environmental
impact include generating electricity from nuclear power,  constructing freeways
when mass transit is more  appropriate  and building  large-scale  dams or other
water projects that encourage  waste.  For all activities not listed above,  the
Adviser will make a determination  on a case-by-case  basis as to whether or not
the activity in question has a positive social and environmental impact.

     Some municipal securities (usually industrial development bonds) are issued
to finance  privately-operated sports facilities,  convention centers, airports,
parking structures,  factories or commercial developments.  In these situations,
the Adviser will make decisions on a  case-by-case  basis as to the social value
of the project in question. For example, the Adviser would probably refrain from
investing in securities that financed a fast-food operation,  but probably would
invest in an issue used to construct a plant that provided  substantial benefits
to the local community and had no negative  environmental  consequences.  In the
case of a project  benefiting  a  specific  company,  the Fund will apply to the
company the social  criteria  listed under the "Social  Policy"  heading in this
Prospectus.

     In the case of a sports facility,  it might have positive  benefits such as
jobs, community pride, economic development and family activities.  On the other
hand, a new sports  facility might have negative  environmental  consequences or
put too much demand on community financial resources for the benefit of a sports
franchise  owner to the detriment of more  important  community  needs.  Another
important   consideration  regarding  a  sports  stadium  might  be  whether  it
encouraged  public  transit or caused more traffic  jams. In all cases such as a
sports facility where the Trustees have not determined whether an activity has a
positive or negative  social/environmental  impact, the Adviser will balance all
the factors it deems relevant and make a determination if a given security meets
the Trust's social criteria.

     As a fundamental  policy,  with respect to 75% of its net assets,  the Fund
will not purchase a security if, as a result of the investment,  more than 5% of
its assets would be in the securities of any single  issuer.  (For this purpose,
each  political  subdivision,  agency or  instrumentality  and each  multi-state
agency which issues industrial  development bonds on behalf of a private entity,
will be regarded as a separate issuer for determining the diversification of the
Fund.)

     Under normal  circumstances,  the Fund intends to invest 100% of its assets
in  California  municipal  obligations.  As a matter of  fundamental  investment
policy,  the  Fund  will  invest  at  least  80%  of  its  assets  in  municipal
obligations, the interest on which will be free from federal income taxation. As
an  operating  policy,  the Fund  will  invest  at least  65% of its  assets  in
California  municipal  obligations.  Usually, the Fund will substantially exceed
these  minimum  requirements,  but the Fund may  invest  up to 20% of  assets in
private  activity bonds that may be subject to the federal  alternative  minimum
tax.

     Developments  in  California  could  adversely  affect the market values or
marketability on municipal  securities  issued in the State or could result in a
default. The economic condition of the State affects tax revenues and could have
an adverse effect on municipal obligations. What follows is a discussion of some
of the more  important  legal and  financial  trends.  This  discussion is based
partly on  information  drawn from official  prospectuses  and statements of the
State of California.

Limitations on Taxes and Appropriations

     Several  initiatives  approved in recent  years could have an impact on the
availability  of revenues  used to pay  California  municipal  obligations.  For
example,  some  municipal  securities  held in the Fund  may  depend  wholly  or
partially  on property  taxes as a revenue  source for  payment of interest  and
principal.  Article XIIIA,  popularly known as Proposition 13, limits ad valorem
property taxes (property taxes based on the property's value) to 1% of full cash
value of the property and limits  increases in assessments to 2% per year except
in the case of new  construction  or a change in ownership.  However,  if voters
approve a bond  issue,  property  taxes may be raised  above the 1% level to pay
debt service on that bond.

     In  1986,  voters  approved  Proposition  62  which  imposed  limits  on  a
locality's  raising or levying general taxes.  Major portions of this initiative
were overturned in court soon after its passage in 1986.  However,  in September
1995, the California Supreme Court made a ruling supporting Proposition 62.

     Article XIIIB (known as the Gann  Initiative),  enacted in 1979 via a voter
initiative, subjects State and local governments to annual spending limitations.
These limitations are adjusted annually to reflect changes in cost of living and
population and only apply to the appropriation of "proceeds of taxes." Spendable
funds  exempted  from these  appropriation  limits  include the proceeds of bond
issues and revenue from user fees. Debt service on bonds issued prior to January
1,  1979,  or  subsequently  authorized  by  voters  is  not  subject  to  these
limitations.

     Article XIIIB's appropriation limitations did not constrain most California
governmental  entities until the mid and late 1980's when many of these entities
approached their Article XIIIB spending  limits.  The passage of Proposition 111
in 1990 allowed for greater increases in appropriation levels.

     In November 1988,  voters approved  Proposition 98, a combined  initiative,
constitutional amendment and statute guaranteeing minimum State funding for K-12
school districts and community college districts at a level equal to the greater
of  (a)  the  same  percentage  of  general  fund  revenues  as  the  percentage
appropriated   to  such  districts  in  1986-87  or  (b)  the  amount   actually
appropriated to such districts from the general fund in the previous fiscal year
adjusted for growth in enrollment and changes in cost of living.

     In June 1990,  California voters approved Proposition 111 which allowed for
some  increase  in  appropriation  levels,  but  provided  that  one-half of all
revenues  in excess of the  state's  appropriation  limit must be  allocated  to
public schools and community colleges.  Since Proposition 98 and 111 allocated a
minimum funding level to schools,  this could  potentially  reduce the resources
available  for other State  programs  and put  pressure on issuers of  municipal
obligations.

                                       B-6


<PAGE>



     In November 1996, voters approved  Proposition 218. Proposition 218 further
restricts  the  ability of local  governments  to levy  special  assessments  or
property-related fees without voter approval.

     Proposition 13, the Gann Initiative,  Proposition 98,  Proposition 111, and
Proposition  218 were adopted as measures that qualified for the ballot pursuant
to  California's  initiative  process.  Other  initiatives  or similar  measures
affecting the  availability of revenue to pay California  municipal  obligations
could be adopted in the future.

State Financial Condition

     State  General  Fund  revenues  are  principally  derived  from  California
personal  income tax (44% of total  revenues),  sales tax (35%),  corporate  tax
(12%) and the gross premium tax on insurance  (3%). All of these revenue sources
can be affected by California's economic conditions.

     From mid-1990 to late 1993, California suffered the worst economic,  fiscal
and budget  conditions  since the 1930's.  The weak economy lowered tax revenues
and increased the need for social welfare  expenditures causing recurring budget
deficits.  Due to budgetary  and fiscal  stress,  between  October 1991 and July
1994, ratings on the State's general obligation bonds were reduced from AAA to A
by S&P, from Aaa to A1 by Moody's and from AAA to A by Fitch.

     Since the passage of  Proposition  13,  property tax  revenues  received by
local  governments  have  dropped  by over  50%.  In  response,  the  California
Legislature has provided  substantial  additional revenue for local governments.
Because  of  budgetary  pressure  and  limits on  allocations  of tax  revenues,
California's  state government has been shifting program  responsibilities  from
the state to county  and city  governments.  To date,  most  changes  in program
responsibilities  from the state to local  governments  have been  balanced with
increases  in  funding.  However,  cuts in State  aid that are not  balanced  by
funding  increases could hurt financially  stressed local  government  entities,
particularly   counties.   Certain  California   municipal   securities  may  be
obligations  of  issuers  which  rely in  whole or in part on  California  state
revenues for payment of these obligations. The proportion of the State's General
Fund that  will be  distributed  in the  future to  counties,  cities  and their
various entities, is unclear.

Revenues of Health Care Institutions

     Certain  California  tax-exempt  securities  may be  obligations  which are
payable solely from the revenues of health care  institutions.  Certain measures
taken under federal or California  law to reduce health care costs may adversely
affect revenues of health care institutions and, consequently,  payment on those
municipal obligations.

Revenues Secured by Deeds of Trust

     Some California  municipal  securities may be obligations which are secured
in whole or in part by a mortgage or deed of trust on real property.  An example
would be bonds issued to finance low and  moderate  income  housing.  Because of
provisions of California law, the effective  minimum period for foreclosing on a
mortgage  could be in excess of seven  months from the time of initial  default.
This delay could disrupt the flow of revenue  available to an issuer for payment
of debt service if such defaults  occur with respect to a substantial  number of
mortgages or deeds of trust. Other aspects of California law could further delay
foreclosure  proceedings  in the  event of a default  and  disrupt  payments  on
municipal obligations.

                                       B-7


<PAGE>


Assessment Bonds (Mello-Roos Bonds)

     Typically,  these bonds are secured by land undeveloped as of the issuance.
The  plan is for  the  land to be  developed  using  funds  from  the  issuance.
Declining  real estate values or a drop in real estate sales activity can result
in  canceled or delayed  development  along with  increased  default  risk.  The
special assessments or taxes securing these bonds are not the personal liability
of the owner of the property  assessed,  so the lien on the property is the only
security for these bonds. Furthermore, in the event of delinquency in payment of
assessments or taxes on the properties  involved,  the issuer is not required to
make payments on the bonds,  except in some  instances  where there is a reserve
account for bond payments.

Redevelopment Agency Debt

     "Tax Allocation" bonds issued by redevelopment  agencies can be affected by
property  tax  limitations  because  these bonds are secured by the  increase in
assessed valuation expected after a redevelopment  project is completed.  Should
the project not be  completed,  perhaps  because of a natural  disaster  like an
earthquake,  there could be no increase in assessed  property  values to pay off
the bonds.  Standard & Poor's or Moody's  stopped  rating tax  allocation  bonds
after the  passage  of  Articles  XIIIA and XIIIB,  and since have only  resumed
rating selected bonds of this nature.

Seismic Activity

     California  is a  geologically  active  area  subject to  earthquakes.  Any
California  municipal  security  could be adversely  affected by a  catastrophic
earthquake.  For  example,  a project  might not be completed or might suffer an
interruption  in  revenue-generating  capacity,  or property  values  might drop
resulting in reduced tax assessments.

Orange County Default

     In December of 1994,  Orange County declared  bankruptcy after  discovering
that its  Treasurer  had invested in risky  derivative  securities  which caused
enormous  losses  to the  county's  investment  fund.  Estimates  of the  losses
approximate  $1.7 billion.  This bankruptcy  disturbed the California  municipal
bond  market and the market  value of  uninsured  Orange  County  bonds  dropped
sharply.  Because the California Tax-Exempt Fund held no uninsured Orange County
bonds,  it was not  substantially  affected  by the  Orange  County  bankruptcy.
However,  other California  municipalities  may mismanage their investment funds
and, in the future,  they may also suffer  losses  which might have an effect on
the Fund in that  the  market  value of some  municipal  securities  might  drop
substantially.

and Officers owned less than 1% of the voting securities of each fund.

                             PERFORMANCE ADVERTISING

     Each Fund of the Trust may advertise  "total return." The Trust  calculates
total  return  by taking  the  total  number  of Fund  shares  purchased  with a
hypothetical  $1,000  investment,  adding all additional  Fund shares  purchased
within the period  with  reinvested  dividends,  calculating  the value of those
shares at the end of the period and  dividing  the result by the initial  $1,000
investment.  No  adjustments  are made to reflect  any income  taxes  payable by
shareholders on distributions paid by a Fund. For periods of more than one year,
the  cumulative  total return is then  adjusted for the number of years,  taking
compounding  into account to calculate  average  annual total return during that
period.  A Fund will quote total return for the most recent  one-year period and
the average  annual  total  return  will be quoted for the most recent  five-and
ten-year periods, or for the life of the Fund, if shorter.

     Total return is computed according to the following formula:

                                 P(1 + T)n = ERV

where P = a hypothetical initial payment of $1,000, T = total return, n = number
of  years  and  ERV =  ending  redeemable  value.  Total  return  is  historical
information and is not intended to indicate future performance.

provide  additional  information,  such as the particular  category to which the
ranking relates,  the number of funds in that category,  the criteria upon which
the  ranking  is based,  and the effect of sales  charges,  fee  waivers  and/or

Yield of Equity Income, Fixed-Income and California Tax-Exempt Funds

     Each fund may also advertise its yield from time to time.  Yield quotations
are  historical  and are not  intended to  indicate  future  performance.  Yield
quotations  refer to the  aggregate  imputed  yield-to-maturity  of each  Fund's
investments  based on the market value as of the last day of a given  thirty-day
or one-month period less accrued expenses (net of reimbursements) divided by the
average daily number of outstanding  Fund shares  entitled to receive  dividends
times the net asset value on the last day of the period,  compounded  on a "bond
equivalent,"  or  semiannual  basis.  The  yield is  computed  according  to the
following formula:

                            Yield = 2 [(a-b + 1)6 -1]

                                       cd

where a = dividends  and interest  earned  during the period using the aggregate
imputed yield to maturity for each of the Fund's investments as noted above: b =
expenses  accrued for the period (net of  reimbursement);  c = the average daily
number of shares  outstanding  during the period  that were  entitled to receive
dividends; and d = the net asset value per share on the last day of the period.

For the 30-day  period from  December 1, 1999 through  December  31,  1999,  the
yields of the Equity  Income  Fund,  the  Fixed-Income  Fund and the  California
Tax-Exempt Fund were 1.15%, 6.50% and 4.18% respectively.

Effective Yield

     The California  Tax-Exempt Fund may also quote a tax-equivalent yield which
demonstrates   the  taxable  yield  necessary  to  produce  an  after-tax  yield
equivalent to that of a fund which invests in tax-exempt obligations. Such yield
is computed by dividing  that portion of the  California  Tax-Exempt  Fund yield
(computed  as  indicated  above)  which is  tax-exempt  by one minus the highest
applicable  income tax rate and adding the product to that portion of the Fund's
yield  that is not  tax-exempt.  For the 30-day  period  from  December  1, 1999
through December 31, 1999, the tax equivalent yield of the California Tax-Exempt
Fund was 7.60%.

                                   THE ADVISER

     Parnassus  Investments acts as the Trust's  investment  adviser.  Under its
Investment Advisory Agreement  ("Agreement") with the Trust, the Adviser acts as
investment  adviser for each Fund and subject to the supervision of the Board of
Trustees, directs the investments of each Fund in accordance with its investment
objective,  policies and  limitations.  The Adviser also provides the Trust with
all  necessary  office  facilities  and  personnel  for  servicing  the  Trust's
investments  and pays the  salaries and fees of all officers and all Trustees of
the Trust who are  "interested  persons"  under the 1940 Act.  The Adviser  also
provides the management and administrative  services necessary for the operation
of the Trust including supervising relations with the custodian, transfer agent,
independent accountants and attorneys. The Adviser also prepares all shareholder
communications,  maintains the Trust's  records,  registers  the Trust's  shares
under state and federal  laws and does the staff work for the Board of Trustees.
Jerome L. Dodson owns all the outstanding stock of the Adviser and, thus, can be
considered the "control person" of the Adviser.

     For its services,  the Trust, under the Agreement,  pays the Adviser a fee,
computed  and  payable  at the  end  of  each  month  at  the  following  annual
percentages  of average daily net assets:  for the Equity Income Fund,  0.75% of
the first $30  million,  0.70% of the next $70  million  and 0.65% of the amount
above $100 million; and for the Fixed-Income Fund and the California  Tax-Exempt
Fund, the fee is 0.50% of the first $200 million, 0.45% of the next $200 million
and  0.40% of the  amount  above  $400  million.  During  1997,  1998 and  1999,
Parnassus  Investments  received the following sums under the Agreement from the
following  funds:  Equity  Income Fund  $157,501  in 1997,  $196,661 in 1998 and
$229,333 in 1999;  California  Tax-Exempt Fund $10,911 in 1997,  $14,135 in 1998
and  $18,927  in 1999;  Fixed-Income  Fund  $6,667 in 1997,  $10,393 in 1998 and
$16,392 in 1999.

     In addition to the fee payable to the Adviser, the Trust is responsible for
its  operating  expenses,  including:  (i)  interest and taxes;  (ii)  brokerage
commissions;  (iii) insurance  premiums;  (iv)  compensation and expenses of its
Trustees  other  than those  affiliated  with the  Adviser;  (v) legal and audit
expenses;  (vi) fees and expenses of the Trust's  custodian,  transfer agent and
accounting  services  agent;  (vii)  expenses  incident  to the  issuance of its
shares,  including  issuance on the  payment of or  reinvestment  of  dividends;
(viii) fees and expenses  incident to the  registration  under  federal or state
securities laws of the Trust or its shares; (ix) expenses of preparing, printing
and mailing reports and notices and proxy material to shareholders of the Trust;
(x)  all  other  expenses   incidental  to  holding   meetings  of  the  Trust's
shareholders;  (xi) dues or  assessments of or  contributions  to the Investment
Company  Institute,  the Social  Investment  Forum or any successor;  (xii) such
nonrecurring expenses as may arise, including litigation affecting the Trust and
the legal obligations for which the Trust may have to indemnify its officers and
Trustees  with  respect  thereto.  In  allocating  brokerage  transactions,  the
investment  advisory  agreement  states that the Adviser may  consider  research
provided by brokerage firms or whether those firms sold shares of the Fund.

     The  Agreement  provides  that the Adviser shall not be liable to the Trust
for any loss to the Trust except by reason of the Adviser's 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 Agreement.

                                      B-12

     Pursuant to a written  agreement with the Trust,  Parnassus  Investments is
the fund accounting  agent for all three funds in The Parnassus Income Trust. In
this capacity,  Parnassus  Investments  handles all fund  accounting and pricing
services,  including calculating the daily net asset values. For its services as
fund accountant,  PI received the following  amounts from the Equity Income Fund
for 1997, 1998 and 1999  respectively:  $35,042,  $35,300 and $34,250;  from the
Fixed-Income  Fund for 1997,  1998 and 1999  respectively:  $8,812,  $8,800  and
$9,600;  and  from  the  California  Tax-Exempt  Fund  for  1997,  1998 and 1999
respectively: $6,133, $5,900 and $6,150.

     Also pursuant to a written agreement with the Trust,  Parnassus Investments
serves  as  the  Trust's  underwriter  (or  Distributor).   As  such,  Parnassus
Investments makes a continuous  offering of each fund's shares.

Portfolio Transactions and Brokerage

     The Agreement  states that in connection with its duties to arrange for the
purchase and the sale of  securities  held in the portfolio of a fund by placing
purchase  and  sale  orders  for  the  Fund,   the  Adviser  shall  select  such
broker-dealers  ("brokers") as shall, in the Adviser's judgement,  implement the
policy of the Trust to achieve  "best  execution,"  i.e.,  prompt and  efficient
execution at the most favorable securities price. In making such selection,  the
Adviser is authorized in the  Agreement to consider the  reliability,  integrity
and  financial  condition  of the  broker.  The  Adviser is also  authorized  to
consider whether the broker provides  brokerage and/or research  services to the
Trust  and/or  other  accounts of the  Adviser.  The  Agreement  states that the
commissions  paid to such brokers may be higher than  another  broker would have
charged if a good faith determination is made by the Adviser that the commission
is  reasonable in relation to the services  provided,  viewed in terms of either
that particular transaction or the Adviser's overall  responsibilities as to the
accounts as to which it  exercises  investment  discretion  and that the Adviser
shall use its judgement in determining  that the amount of commissions  paid are
reasonable in relation to the value of brokerage and research  services provided
and need not place nor attempt to place  specific  dollar value on such services
nor on the portion of commission rates reflecting such services.

     The Trust recognizes in the Agreement that, on any particular  transaction,
a  higher  than  usual  commission  may be  paid  due to the  difficulty  of the
transaction  in question.  The Adviser is also  authorized  in the  Agreement to
consider sales of Fund shares as a factor in the selection of brokers to execute
brokerage  and  principal  transactions,  subject to the  requirements  of "best
execution."

     The  research  services  discussed  above may be in written form or through
direct  contact with  individuals  and may include  information as to particular
companies and securities as well as market,  economic or institutional areas and
information assisting the Fund in the valuation of its investments. The research
which the Adviser  receives for a Fund's brokerage  commissions,  whether or not
useful to that Fund,  may be useful to the Adviser in managing  the  accounts of
the Adviser's other advisory clients.  Similarly,  the research received for the
commissions  of such  accounts  may be  useful  to a Fund.  To the  extent  that
electronic  or other  products  provided  by brokers are used by the Adviser for
research purposes,  the Adviser will use its best judgement to make a reasonable
allocation of the cost of the product attributable to non-research use.

     Research  services  provided  through  brokerage  will be  those  providing
information  and analyses that directly  assist the portfolio  manager in making
investment  decisions.  Examples of such  research  services  include  Bloomberg
information  and  research,  HOLT  cash  flow  analyses,  KLD  social  research,
publications   containing   investment   information  and   recommendations  and
individual reports written on specific companies.

     During  1999,  the Equity  Income  Fund paid  PaineWebber,  Inc. a total of
$35,241  in  brokerage  commissions  under a  "soft  dollar"  agreement  whereby
PaineWebber would provide research services to the Fund. During 1999, the Equity
Income Fund  maintained a joint account with The Parnassus Fund at Salomon Smith
Barney and the two funds  together  directed  $29,000 in  brokerage to pay for a
Bloomberg  terminal.  Allocation  of  commissions  and  research  services  were
approximately 80% to The Parnassus Fund and 20% to the Equity Income Fund.

     The  Adviser  may also use Fund  brokerage  commissions  to reduce  certain
expenses of that Fund subject to "best execution." For example,  the Adviser may
enter into an  agreement  to have a  brokerage  firm pay part or all of a Fund's
custodian fee since this benefits the Fund's shareholders.

     In the over-the-counter market,  securities are generally traded on a "net"
basis with dealers  acting as principal for their own accounts  without a stated
commission  although the price of the security  usually includes a profit to the
dealer.  Money market  instruments  usually  trade on a "net" basis as well.  On
occasion,  certain money market  instruments  may be purchased  directly from an
issuer in which case no  commissions  or  discounts  are paid.  In  underwritten
offerings, securities are purchased at a fixed price which includes an amount of
compensation  to the  underwriter,  generally  referred to as the  underwriter's
concession or discount.

     During 1997,  1998 and 1999, the Equity Income Fund paid $46,914,  $149,000
and  $40,886,  respectively  in brokerage  commissions.  Of these  amounts,  the
following  was paid in  conjunction  with  research  services:  $46,914 in 1997,
$119,200  in 1998 and  $35,241  in 1999.  The Fund  paid  substantially  more in
brokerage  commisions in 1998 than for 1997 or 1999 because it restructured  the
portfolio  in 1998 to change  from a  balanced  fund to an equity  income  fund.
Neither  the  Fixed-Income   Fund  nor  the  California   Tax-Exempt  Fund  paid
commissions  in 1997,  1998 or 1999 since these Funds buy their  securities on a
"net" basis that includes the dealer mark-up.

     The Equity Income Fund's portfolio  turnover rate went from 166.32% in 1998
to 39.53% in 1999.  The  reason for the  decrease  was  because  the fund had an
extraordinarily  high  turnover  ratio in 1998 due to its change from a balanced
fund to an equity income fund and the rate declined to normal levels in 1999.

     Parnassus  Investments  clients other than The Parnassus  Income Trust that
have objectives similar to the Trust. Normally, orders for securities trades are
placed separately for each client.  However,  some recommendations may result in
simultaneous  buying or selling of securities along with the Trust. As a result,
the demand for securities being purchased or the supply of securities being sold
may  increase,  and this  could  have an  adverse  effect  on the price of those
securities.  Parnassus  Investments  does not favor one client  over  another in
making  recommendations  or placing orders,  and in some situations,  orders for
different clients may be grouped together.  In certain cases where the aggregate
order is executed in a series of  transactions at various prices on a given day,
each  participating  client's  proportionate  share of such order  reflects  the
average  price paid or received  with respect to the total order.  Also,  should
only a partial order be filled,  each client would ordinarily receive a pro rata
share of the total order.

                                 NET ASSET VALUE

     In  determining  the net asset  value or NAV of the  Equity  Income  Fund's
shares,  common  stocks that are listed on  national  securities  exchanges  are
valued at the last sale price on the exchange on which each stock is principally
traded  as of the  close  of the  New  York  Stock  Exchange  ("NYSE")(which  is
currently 4:00 p.m. New York time) or, in the absence of recorded  sales, at the
average of readily available closing bid and asked prices on such exchanges. The
NYSE is closed on the following  holidays:  New Year's Day,  Martin Luther King,
Jr. Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence  Day, Labor
Day,  Thanksgiving Day and Christmas Day.  Securities traded on The Nasdaq Stock
Market are also valued at the last  recorded sale price as of 4:00 p.m. New York
time.  Other  unlisted  securities  are  valued at the  quoted bid prices in the
over-the-counter market.

                                      B-14

     Bonds and other fixed-income securities are valued by a third-party pricing
service. Municipal bonds are ordinarily valued as of the close of trading on the
NYSE,  usually at 4:00 p.m. New York time.  Taxable  bonds and other  securities
held by the Fixed-Income  Fund are ordinarily valued one hour prior to the close
of the NYSE, normally at 3:00 p.m. New York time.

      Securities  and other assets for which market  quotations  are not readily
available  are  valued at their fair  value as  determined  in good faith by the
Adviser under  procedures  established by and under the general  supervision and
responsibility  of the Trust's Board of Trustees.  Short-term  investments which
mature in less than 60 days are valued at  amortized  cost  (unless the Board of
Trustees  determines  that this method does not  represent  fair value) if their
original  maturity was 60 days or less or by amortizing the value as of the 61st
day prior to maturity if their original term to maturity exceeded 60 days.

                              Taxation Of The Trust

     By paying out  substantially  all its net  investment  income  (among other
things),  each  Fund has  qualified  as a  regulated  investment  company  under
Subchapter M of the Internal Revenue Code of 1986. Each Fund intends to continue
to  qualify  and,  if so, it will not pay  federal  income tax on either its net
investment income or on its net capital gains. Instead, each shareholder will be
responsible for his or her own taxes.

                              SHAREHOLDER SERVICES

Systematic Withdrawal Plan

     A Systematic  Withdrawal  Plan (the "Plan") is available  for  shareholders
having shares of a Fund with a minimum  value of $10,000.  The plan provides for
monthly checks in an amount not less than $100 or quarterly  checks in an amount
not less than $200.

     Dividends and capital gain  distributions on shares held under the Plan are
invested in additional full and fractional shares at net asset value. Withdrawal
payments  should not be considered as  dividends,  yield or income.  If periodic
withdrawals   continuously   exceed   reinvested   dividends  and  capital  gain
distributions,  the shareholder's  original  investment will be  correspondingly
reduced and ultimately exhausted.

     Furthermore,  each  withdrawal  constitutes  a redemption of shares and any
gain or loss realized must be recognized for federal income tax purposes.

Tax-Sheltered Retirement Plans

     Through  the  Distributor,   retirement  plans  are  available:  Individual
Retirement  Accounts  ("IRAs") and  Simplified  Employee  Pension  Plans (SEPs).
Adoption  of such plans  should be on advice of legal  counsel  or tax  adviser.
Retirement  accounts  have a  minimum  initial  investment  of  $500,  and  each
subsequent  investment must be at least $50. For further  information  regarding
plan administration,  custodial fees and other details, investors should contact
the Distributor.

Purchases and Redemptions Through a Broker-Dealer

     Broker-dealers  may  place  orders  on behalf of  clients  by  calling  the
Distributor. If a client places an order with a broker-dealer prior to 1:00 p.m.
San Francisco time on any business day and the broker-dealer  forwards the order
to the Distributor  prior to 1:00 p.m. San Francisco time on that day, the order
will be  processed  at the  NAV  calculated  as of  1:00  p.m.  that  same  day.
Otherwise, the order will be processed at the NAV next calculated,  typically as
of the close of the New York Stock Exchange  ("NYSE") the next business day. The
broker-dealer  is  responsible  for placing  purchase  orders  promptly with the
Distributor and for forwarding payment within three business days.

     You may sell or redeem your Fund shares by offering  them for  "repurchase"
or "redemption" directly to the Fund or through your dealer. If you offer shares
through  your dealer  before the close of the New York Stock  Exchange  and your
dealer  transmits your offer to the Distributor  before 1:00 p.m. (San Francisco
time) that day, you will  receive  that day's price.  Your dealer may charge for
this service.

                                     GENERAL

     The Trust was organized as a Massachusetts business trust on August 8,1990.
The  Declaration of Trust provides the Trustees will not be liable for errors of
judgment  or mistakes of fact or law,  but nothing in the  Declaration  of Trust
protects a Trustee  against any liability to which he or she would  otherwise be
subject  by reason of  willful  misfeasance,  bad  faith,  gross  negligence  or
reckless disregard of the duties involved in the conduct of his or her office.

Shareholders  are entitled to one vote for each full share held (and  fractional
votes for  fractional  shares) and may vote in the  election of Trustees  and on
other matters submitted to meetings of shareholders. It is not contemplated that
regular annual meetings of  shareholders  will be held. The Declaration of Trust
provides that the Fund's  shareholders  have the right,  upon the declaration in
writing or vote of more than two-thirds of its outstanding  shares,  to remove a
Trustee. The Trustees will call a meeting of shareholders to vote on the removal
of a Trustee upon the written  request of the record  holders of ten per cent of
its shares. In addition, ten shareholders holding the lesser of $25,000 worth or
one percent of Fund shares may advise the  Trustees in writing that they wish to
communicate  with other  shareholders for the purpose of requesting a meeting to
remove a Trustee.  The Trustees will then, if requested by the applicants,  mail
at  the  applicants'   expense  the  applicants'   communication  to  all  other
shareholders.  The holders of shares have no pre-emptive  or conversion  rights.
Shares when issued are fully paid and non-assessable. The Fund may be terminated
upon the sale of its assets to another  issuer,  if such sale is approved by the
vote  of the  holders  of  more  than  50% of its  outstanding  shares,  or upon
liquidation  and  distribution  of its  assets,  if  approved by the vote of the
holders of more than 50% of its outstanding  shares.  If not so terminated,  the
Fund will continue indefinitely. No amendment that would have a material adverse
impact upon the rights of the  shareholders  may be made to the  Declaration  of
Trust  without  the  affirmative  vote of the  holders  of more  than 50% of the
Trust's outstanding shares.

Prior to April 1, 1998,  The  Parnassus  Income Trust was known as The Parnassus
Income Fund and each of the Trust's series was known as a Portfolio  rather than
a Fund.

         The Fund's Declaration of Trust permits the Trust to issue an unlimited
number of full and  fractional  shares of  beneficial  interest and to divide or
combine  the  shares to a greater  or lesser  number of shares  without  thereby
changing the proportionate beneficial interest in a Fund of the Trust. Each Fund
has only one class of shares. Each share represents an interest in a Fund of the
Trust  proportionately  equal to the interest of each other share.  Certificates
representing shares will not be issued.  Instead,  each shareholder will receive
an annual statement and an additional statement each time there is a transaction
in the account. These statements will be evidence of ownership. Upon the Trust's
liquidation, all shareholders of the Fund would share pro rata in the net assets
available for distribution to shareholders of the Fund.  Shares of each Fund are
entitled to vote  separately as a group only to the extent  required by the 1940
Act or as permitted by the Trustees.  Trust operating expenses will be allocated
fairly  among the  Funds,  generally  on the basis of their  relative  net asset
value.

                                      B-16

     The  Declaration  of Trust  contains an express  disclaimer of  shareholder
liability  for  its  acts  or  obligations  and  requires  that  notice  of such
disclaimer be given in each agreement,  obligation or instrument entered into or
executed by the Trust or its Trustees.  The  Declaration  of Trust  provides for
indemnification  and  reimbursement  of expenses out of the Trust's property for
any shareholder held personally  liable for its obligations.  The Declaration of
Trust also  provides that the Trust shall,  upon request,  assume the defense of
any claim made against any  shareholder  for any act or  obligation of the Trust
and satisfy any  judgement  thereon.  Thus,  while  Massachusetts  law permits a
shareholder  of a trust such as this to be held  personally  liable as a partner
under certain circumstances,  the risk of a shareholder incurring financial loss
on account of  shareholder  liability  is highly  unlikely and is limited to the
relatively  remote  circumstances in which the Trust would be unable to meet its
obligations.

     The  Declaration  of Trust  further  provides that the Trustees will not be
liable for errors of  judgement  or mistakes of fact or law,  but nothing in the
Declaration of Trust protects a Trustee against any liability to which he or she
would otherwise be subject by reason of willful  misfeasance,  bad faith,  gross
negligence or reckless disregard of the duties involved in the conduct of his or
her office.

Deloitte & Touche LLP, 50 Fremont Street,  San Francisco,  California 94105, has
been selected as the Trust's independent auditors.

Union Bank of California,  475 Sansome Street, San Francisco,  California 94111,
has been selected as the custodian of the Trust's assets.  Shareholder inquiries
should be directed to the Trust.

Parnassus Investments, One Market-Steuart Tower #1600, San Francisco, California
94105,  is the Fund's  transfer agent and accounting  agent.  As transfer agent,
Parnassus  Investments  receives  a fee of  $2.30  per  account  per  month.  As
accounting  agent,  Parnassus  Investments  receives a fee of $50,000  per year.
Jerome L. Dodson,  the Fund's  President,  is the sole  stockholder of Parnassus
Investments.

Code of Ethics

     The Adviser  and the Board of  Trustees of the Fund have  adopted a Code of
Ethics (the Code). The Code permits  personnel  subject to the Code to invest in
securities,  including  securities  that may be  purchased  or held by the Fund.
However, the protective  provisions of the Code prohibit certain investments and
limit such  personnel  from making  investments  during periods when the Fund is
making such investments. The Code is on public file with, and is available from,
the SEC.

Financial Statements

       The Trust's  Annual Report to  shareholders  dated  December 31, 1999, is
expressly  incorporated  by  reference  and  made a part  of this  Statement  of
Additional  Information.  A copy of the Annual Report which contains the Trust's
audited  financial  statements  for the year ending  December 31,  1999,  may be
obtained free of charge by writing or calling the Trust.

                                    APPENDIX

                             CORPORATE BOND RATINGS

Moody's Investors Service, Inc. ("Moody's")

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

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

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

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

Note:  Moody's  applies  numerical  modifiers 1, 2, and 3 in each generic rating
classification from Aa through Caa. The modifier 1 indicates that the obligation
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range ranking;  and the modifier 3 indicates a ranking in the lower end of
that generic rating category.

Standard & Poor's Corporation, a division of The McGraw-Hill Companies, Inc.
("Standard & Poor's"):

AAA

An obligation  rated 'AAA' has the highest rating assigned by Standard & Poor's.
The  obligor's  capacity to meet its financial  commitment on the  obligation is
extremely strong.

AA

An  obligation  rated 'AA' differs from the highest  rated  obligations  only in
small  degree.  The obligor's  capacity to meet its financial  commitment on the
obligation is very strong.

A

An obligation  rated 'A' is somewhat more  susceptible to the adverse effects of
changes in  circumstances  and economic  conditions  than  obligations in higher
rated  categories.  However,  the  obligor's  capacity  to  meet  its  financial
commitment on the obligation is still strong.

BBB

An obligation  rated 'BBB' exhibits  adequate  protection  parameters.  However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened  capacity  of the  obligor to meet its  financial  commitment  on the
obligation.  Obligations  rated 'BB', 'B', 'CCC',  'CC', and 'C' are regarded as
having significant speculative characteristics.  'BB' indicates the least degree
of speculation and 'C' the highest. While such obligations will likely have some
quality  and  protective  characteristics,  these  may be  outweighed  by  large
uncertainties or major exposures to adverse conditions.

                             MUNICIPAL BOND RATINGS

Moody's:

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

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

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

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

Conditional Rating:  Bonds for which the security depends upon the completion of
some act or the fulfillment of some condition are rated conditionally. These are
bonds secured by: (a) earnings of projects under  construction,  (b) earnings of
projects  unseasoned  in  operating  experience,  (c)  rentals  that  begin when
facilities are completed, or (d) payments to which some other limiting condition
attaches.  Parenthetical  rating denotes probable credit stature upon completion
of construction or elimination of basis of condition.

Standard & Poor's

AAA

An obligation  rated 'AAA' has the highest rating assigned by Standard & Poor's.
The  obligor's  capacity to meet its financial  commitment on the  obligation is
extremely strong.

AA

An  obligation  rated 'AA' differs from the  highest-rated  obligations  only in
small  degree.  The obligor's  capacity to meet its financial  commitment on the
obligation is very strong.

A

An obligation  rated 'A' is somewhat more  susceptible to the adverse effects of
changes  in   circumstances   and  economic   conditions  than   obligations  in
higher-rated  categories.  However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

BBB

An obligation  rated 'BBB' exhibits  adequate  protection  parameters.  However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened  capacity  of the  obligor to meet its  financial  commitment  on the
obligation.

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

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

Fitch Investor's Services, Inc.

         The  following  ratings  scale  applies to foreign  currency  and local
currency ratings.

AAA

Highest credit  quality.  `AAA' ratings denote the lowest  expectation of credit
risk. They are assigned only in case of exceptionally strong capacity for timely
payment  of  financial  commitments.  This  capacity  is highly  unlikely  to be
adversely affected by foreseeable events.

AA

Very high credit  quality.  `AA' ratings denote a very low expectation of credit
risk.  They  indicate  very  strong  capacity  for timely  payment of  financial
commitments.  This  capacity  is not  significantly  vulnerable  to  foreseeable
events.

A

High credit  quality.  `A' ratings denote a low  expectation of credit risk. The
capacity for timely payment of financial  commitments is considered strong. This
capacity may, nevertheless, be more vulnerable to changes in circumstances or in
economic conditions than is the case for higher ratings.

BBB

Good  credit  quality.  `BBB'  ratings  indicate  that there is  currently a low
expectation  of credit  risk.  The  capacity  for timely  payment  of  financial
commitments is considered adequate,  but adverse changes in circumstances and in
economic conditions are more likely to impair this capacity.  This is the lowest
investment-grade category.

Note:  Fitch  ratings may be modified by the addition of a plus (+) or minus (-)
sign to show relative  standing  within the major rating  categories.  These are
refinements more closely reflecting strengths and weaknesses,  and are not to be
used as trend indicators.

and as restated effective March 24, 2000:

         WHEREAS,  the Trustees  desire to establish a trust fund under the laws

context may require).

         accordance with the provisions of Article FOURTH.

7.       "Class" refers to the class of Shares of a Series of the Trust
         established in accordance with the provisions of Article

investment or otherwise, sell, sell short, assign, negotiate, transfer, exchange
or otherwise  dispose of or turn to account or realize upon,  securities  (which

limitation of the generality thereof,  be deemed to include any stocks,  shares,
bonds, debentures,  notes, mortgages or other obligations, and any certificates,
receipts, warrants or other instruments representing rights to receive, purchase
or subscribe for the same, or  evidencing  or  representing  any other rights or
interests therein, or in any property or assets) created or issued by any issuer
(which  term  "issuer"  shall for the  purposes  of this  Declaration  of Trust,
without  limitation of the generality  thereof be deemed to include any persons,
firms,  associations,  corporations,  syndicates,  combinations,  organizations,
governments,  or  subdivisions  thereof) or in any other  financial  instruments
whether or not  considered  as securities or  commodities;  and to exercise,  as
owner or holder of any securities or other  financial  instruments,  all rights,
powers and privileges in respect thereof;  and to do any and all acts and things
for the preservation, protection, improvement and enhancement in value of any or
all such securities or other financial instruments.

2. To borrow money and pledge  assets in  connection  with any of the objects or
purposes of the Trust, and to issue notes or other  obligations  evidencing such
borrowings,  to  the  extent  permitted  by the  1940  Act  and  by the  Trust's
fundamental investment policies under the 1940 Act.

3. To  issue  and  sell  its  Shares  in such  amounts  and on  such  terms  and
conditions,  for such  purposes  and for such  amount  or kind of  consideration
(including   without   limitation   thereto,   securities  or  other   financial
instruments)  now or  hereafter  permitted  by the laws of the  Commonwealth  of
Massachusetts and by this Declaration of Trust, as the Trustees may determine.

4. To purchase or otherwise acquire, hold, dispose of, resell, transfer, reissue
or cancel (all without the vote or consent of the Shareholders of the Trust) its
Shares,  in any manner and to the extent now or hereafter  permitted by the laws
of Massachusetts and by this Declaration of Trust.

5.       To conduct its business in all its branches at one or more offices in
Massachusetts and elsewhere in any part of the world, without restriction or
limit as to extent.

6. To carry out all or any of the foregoing objects and purposes as principal or
agent, and alone or with associates or, to the extent now or hereafter permitted
by the laws of  Massachusetts,  as a member of, or as the owner or holder of any
stock of, or share of interest in, any issuer,  and in  connection  therewith to
make or enter into such deeds or contracts  with any issuers and to do such acts
and things and to exercise such powers, as a natural person could lawfully make,
enter into, do or exercise.

7. To do any and all such  further  acts and things and to exercise  any and all
such  further  powers  as may be  necessary,  incidental,  relative,  conducive,
appropriate or desirable for the  accomplishment,  carrying out or attainment of
all or any of the foregoing purposes or objects.

         The foregoing objects and purposes shall, except as otherwise expressly
provided, be in no way limited or restricted by reference to, or inference from,
the terms of any other clause of this or any other Articles of this  Declaration
of Trust,  and shall each be regarded as independent  and construed as powers as
well as objects and purposes, and the enumeration of specific purposes,  objects
and powers shall not be construed to limit or restrict in any manner the meaning
of general terms or the general  powers of the Trust now or hereafter  conferred
by the laws of the Commonwealth of Massachusetts nor shall the expression of one
thing be deemed to exclude another,  though it be of like nature, not expressed;
provided,  however,  that the Trust shall not carry on any business, or exercise
any powers,  in any state,  territory,  district or country except to the extent
that the same may lawfully be carried on or exercised under the laws thereof.

         FOURTH: (a) The beneficial  interest in the Trust shall be divided into
such  transferable  Shares,  without  par  value,  of one or more  separate  and
distinct  Series or  Classes  thereof  as the  Trustees  shall from time to time
create and  establish.  The number of Shares is unlimited  and upon  issuance in
accordance  with the terms  hereof  shall be fully paid and  nonassessable.  The
Trustees  shall have full power and  authority,  in their  sole  discretion  and
without  obtaining any prior  authorization  or vote of the  Shareholders of the
Trust,  to create and establish  (and to change in any manner)  Shares with such
preferences,  terms of conversion,  voting powers,  rights and privileges as the
Trustees may from time to time determine, to divide or combine the Shares into a
greater or lesser number, to classify or reclassify any unissued Shares into one
or more  Series or  Classes  of Shares,  to  abolish  any one or more  Series or
Classes of Shares,  and to take such other  action with respect to the Shares as
the Trustees may deem desirable. Contributions to the Trust may be accepted for,
and Shares  shall be  redeemed  as,  whole  Shares or  1/1,000ths  of a Share or
multiple  thereof.  The  Trustees,  in their  discretion  without  a vote of the
Shareholders,  may divide the Shares of any Series into Classes.  In such event,
each Class of a Series  shall  represent  interests in the assets of that Series
and have identical voting,  dividend,  liquidation and other rights and the same
terms and conditions,  except that expenses allocated to a Class of a Series may
be borne solely by such Class as shall be determined by the Trustees and a Class
of a Series may have exclusive  voting rights with respect to matters  affecting
only that Class.  Without  limiting  the  authority of the Trustees set forth in
this Article FOURTH to establish and designate  Series or Classes,  the Trustees
have established and designated the Series of Shares and Classes, if any, listed
in Schedule A attached hereto and made a part hereof.

         (b) The  establishment  of any Series or Class in addition to those set
forth in (a) above shall be effective  upon the  adoption of a  resolution  by a
majority of the then Trustees setting forth such  establishment  and designation
and the relative  rights and  preferences  of the Shares of such Series or Class
thereof.  At any time that  there are no Shares  outstanding  of any  particular
Series  previously  established and  designated,  the Trustees may by a majority
vote abolish that Series and the establishment and designation  thereof.  At any
time that there are no shares  outstanding of any particular  Class of a Series,
the Trustees may by a majority vote abolish that Class and the establishment and
designation  thereof. The Trustees by a majority vote may change the name of any
Series or Class.

         (c) All  consideration  received  by the Trust for the issue or sale of
Shares  of  a  particular  Series,  together  with  all  assets  in  which  such
consideration  is invested or reinvested,  all income,  earnings,  profits,  and
proceeds  thereof,  including  any proceeds  derived from the sale,  exchange or
liquidation  of  such  assets,  and any  funds  or  payments  derived  from  any
reinvestment  of such  proceeds  in  whatever  form the  same  may be,  shall be
referred to as "assets  belonging  to" that  Series.  In  addition,  any assets,
income,  earnings,  profits, and proceeds thereof,  funds, or payments which are
not  readily  identifiable  as  belonging  to any  particular  Series  shall  be
allocated  by the  Trustees  between and among one or more of the Series in such
manner as they, in their sole  discretion,  deem fair and  equitable.  Each such
allocation  shall be conclusive and binding upon the  Shareholders of all Series
for all purposes,  and shall be referred to as assets  belonging to that Series.
The assets belonging to a particular  Series shall be so recorded upon the books
of the Trust,  and shall be held by the Trustees in Trust for the benefit of the
holders of Shares of that Series. The assets belonging to each particular Series
shall be charged with the  liabilities  of that Series and all expenses,  costs,
charges and reserves  attributable  to that Series except that  liabilities  and
expenses  allocated  solely to a particular  Class shall be borne by that Class.
Any general  liabilities,  expenses,  costs, charges or reserves of the Trust or
Series which are not readily  identifiable as belonging to any particular Series
or Class shall be allocated and charged by the Trustees between or among any one
or more of the Series or Classes in such  manner as the  Trustees  in their sole
discretion deem fair and equitable. Each such allocation shall be conclusive and
binding upon the  Shareholders  of all Series or Classes for all  purposes.  Any
creditor  of any Series  may look only to the  assets of that  Series to satisfy
such creditor's debt. See Article EIGHTH, paragraph 1.

         (d) The ownership of Shares shall be recorded in the books of the Trust
or a  transfer  agent.  The  Trustees  may  make  such  rules  as they  consider
appropriate for the transfer of Shares and similar matters.  The record books of
the Trust or any transfer  agent,  as the case may be, shall be conclusive as to
who are the  holders of Shares and as to the number of Shares  held from time to
time by each.

         (e) The  Trustees  shall  accept  investments  in the  Trust  from such
persons and on such terms as they may from time to time authorize.

         (f)  Shareholders  shall have no preemptive or other right to subscribe
to any  additional  Shares  or  other  securities  issued  by the  Trust  or the
Trustees.

                  FIFTH:  The following provisions are hereby adopted with
respect to voting Shares of the Trust and certain other rights:

1. The Shareholders shall have power to vote (i) for the election of Trustees to
the extent  provided in the By-Laws,  (ii) with respect to the amendment of this
Declaration of Trust as provided in Article  EIGHTH,  paragraph 12, (iii) to the
same extent as the shareholders of a Massachusetts  business corporation,  as to
whether  or not a court  action,  proceeding  or  claim  should  be  brought  or
maintained  derivatively  or as a class  action  on  behalf  of the Trust or the
Shareholders,  and (iv) with respect to such additional  matters relating to the
Trust  as may be  required  by the  1940  Act or  authorized  by  law,  by  this
Declaration of Trust, or the By-Laws of the Trust or any registration  statement
of the Trust with the  Commission or any State,  or as the Trustees may consider
desirable.  On any matter  submitted to a vote of the  Shareholders,  all Shares
shall be voted by individual Series,  except: (i) when required by the 1940 Act,
Shares shall be voted in the aggregate and not by  individual  Series;  and (ii)
when the Trustees have  determined that the matter affects only the interests of
one or more Classes,  then only the  Shareholders of such Class or Classes shall
be entitled to vote thereon.

2. At all meetings of  Shareholders  each  Shareholder  shall be entitled to one
vote for each Share  standing in his name on the books of the Trust on the date,
fixed in accordance with the By-Laws, for determination of Shareholders entitled
to vote at such meeting  except (if so  determined by the Board of Trustees) for
Shares  redeemed  prior  to  the  meeting.  Any  fractional  Share  shall  carry
proportionately all the rights of a whole Share, including the right to vote and
the  right to  receive  dividends.  The  presence  in  person or by proxy of the
holders of  one-third  of the Shares  outstanding  and  entitled to vote thereat
shall constitute a quorum at any meeting of the Shareholders.  If at any meeting
of the Shareholders there shall be less than a quorum present,  the Shareholders
present at such meeting may, without further notice,  adjourn the same from time
to time until a quorum shall attend,  but no business shall be transacted at any
such adjourned  meeting  except such as might have been lawfully  transacted had
the meeting not been adjourned.

3. Each Shareholder,  upon request to the Trust in proper form determined by the
Trust,  shall be  entitled to require the Trust to redeem all or any part of the
Shares standing in the name of the Shareholder. The method of computing such net
asset  value,  the time at which such net asset value shall be computed  and the
time within which the Trust shall make payment therefor,  shall be determined as
hereinafter   provided  in  Article  SEVENTH  of  this   Declaration  of  Trust.
Notwithstanding the foregoing, the Trustees, when permitted or required to do so
by the 1940 Act, may suspend the right of the  Shareholders to require the Trust
to redeem Shares.

4. No Shareholder shall, as such holder, have any right to purchase or subscribe
for any security of the Trust which it may issue or sell, other than such right,
if any, as the Trustees, in their discretion, may determine.

5. Notwithstanding  anything elsewhere contained in this Declaration of Trust or
in the By-Laws of the Trust,  so long as the By-Laws of the Trust do not provide
for regular annual meetings of Shareholders  of the Trust,  the  Shareholders of
the Trust shall have such rights, and the Trust, the Board of Trustees,  and the
Trustees  shall have such  obligations as would exist if the Trust were a common
law trust  covered by Section 16(c) of the 1940 Act. In the event that the Trust
has outstanding  two or more Series,  each such Series shall be considered as if
it were a separate common law trust covered by said Section 16(c).  However, the
Trust may at any time or from time to time  apply to the  Commission  for one or
more  exemptions  from all or part of said  Section  16(c) and, if an  exemptive
order or orders are  issued by the  Commission,  such  order or orders  shall be
deemed part of said Section 16(c) for the purposes of this paragraph 5.

                  SIXTH:  The person who shall act as initial Trustees are the
persons initially executing this Declaration of Trust or any counterpart
thereof.

         However,  the  By-Laws of the Trust may fix the number of Trustees at a
number greater than that of the number of initial Trustees and may authorize the
Trustees to increase or decrease the number of Trustees,  to fill the  vacancies
created by any such  increase  in the number of  Trustees,  to set and alter the
terms of office of the  Trustees  and to lengthen  or lessen  their own terms or
make their terms of  indefinite  duration,  all subject to the 1940 Act.  Unless
otherwise  provided  by the  By-Laws  of the  Trust,  the  Trustees  need not be
Shareholders.

                  SEVENTH:  The following provisions are hereby adopted for the
purpose of defining, limiting and regulating the powers of the Trust and of the
Trustees and Shareholders.

1. As soon as any Trustee is duly  elected by the  Shareholders  or the Trustees
and shall have  accepted  this  trust,  the Trust  estate  shall vest in the new
Trustee or Trustees,  together with the continuing  Trustees without any further
act or conveyance, and he shall be deemed a Trustee hereunder.

2. The death, declination,  resignation,  retirement,  removal, or incapacity of
the  Trustees,  or any one of them,  shall not  operate to annul the Trust or to
revoke any existing agency created  pursuant to the terms of this Declaration of
Trust.

3. The assets of the Trust shall be held  separate and apart from any assets now
or  hereafter  held in any  capacity  other  than as  Trustee  hereunder  by the
Trustees or any successor Trustees.  All of the assets of the Trust shall at all
times be  considered  as vested in the  Trustees.  Except  as  provided  in this
Declaration of Trust,  no  Shareholder  shall have, as such holder of beneficial
interest in the Trust,  any  authority,  power or right  whatsoever  to transact
business  for or on  behalf of the  Trust,  or on  behalf  of the  Trustees,  in
connection  with the  property or assets of the Trust,  or in any part  thereon,
except the  rights to receive  the  income  and  distributable  amounts  arising
therefrom as set forth herein.

4. The Trustees in all instances  shall act as principals,  and are and shall be
free from the control of the  Shareholders.  The Trustees  shall have full power
and  authority  to do any  and all  acts  and to make  and  execute  any and all
contracts and  instruments  that they may consider  necessary or  appropriate in
connection  with the management of the Trust.  The Trustees shall not in any way
be bound or  limited  by  present  or future  laws or customs in regard to Trust
investments,  but  shall  have  full  authority  and  power  to make any and all
investments which they, in their uncontrolled  discretion,  shall deem proper to
accomplish the purposes of this Trust.  Subject to any applicable  limitation in
this  Declaration  of Trust or in the By-Laws of the Trust,  the Trustees  shall
have power and authority:

(a) to adopt By-Laws not  inconsistent  with this Declaration of Trust providing
for the conduct of the business of the Trust and to amend and repeal them to the
extent that they do not reserve that right to the Shareholders;

(b)      to elect and remove such officers and appoint and terminate such
officers as they consider appropriate with or without cause;

(c)      to employ a bank or trust company as custodian of any assets of the
Trust subject to any conditions set forth in this Declaration of Trust or in the
By-Laws;

(d)      to retain a transfer agent and Shareholder servicing agent, or both;

(e)      to provide for the distribution of Shares either through a principal
underwriter or the Trust itself or both;

(f)      to set record dates in the manner provided for in the By-Laws of the
Trust;

(g)      to delegate such authority as they consider desirable to any officers
of the Trust and to any agent, custodian or underwriter;

(h) to vote or give assent, or exercise any rights of ownership, with respect to
stock or other  securities or property held in Trust  hereunder;  and to execute
and deliver  powers of attorney to such person or persons as the Trustees  shall
deem proper,  granting to such person or persons such power and discretion  with
relation to securities or property as the Trustees shall deem proper;

(i)      to exercise powers and rights of subscription or otherwise which in any
manner arise out of ownership of securities held in trust hereunder;

(j) to hold any security or property in a form not indicating any trust, whether
in bearer,  unregistered or other  negotiable form; or either in its own name or
in the name of a custodian or a nominee or  nominees,  subject in either case to
proper  safeguards  according to the usual  practice of  Massachusetts  business
trusts or investment companies; (k) to consent to or participate in any plan for
the reorganization,  consolidation or merger of any corporation or concern,  any
security  of which is held in the  Trust;  to consent  to any  contract,  lease,
mortgage,  purchase or sale of property by such  corporation or concern,  and to
pay calls or subscriptions with respect to any security held in the Trust;

(l)      to compromise, arbitrate, or otherwise adjust claims in favor of or
against the Trust or any matter in controversy including, but not limited to,
claims for taxes;

(m)      to make, in the manner provided in the By-Laws, distributions of income
 and of capital gains to Shareholders;

(n)      to borrow money to the extent and in the manner permitted by the 1940
Act and the Trust's fundamental policy thereunder as to borrowing; and

(o) to enter into investment  advisory or management  contracts,  subject to the
1940 Act, with any one or more corporations,  partnerships, trusts, associations
or other  persons;  if the  other  party or  parties  to any such  contract  are
authorized to enter into securities  transactions  on behalf of the Trust,  such
transactions shall be deemed to have been authorized by all of the Trustees.

5. No one dealing with the Trustees  shall be under any  obligation  to make any
inquiry  concerning the authority of the Trustees,  or to see to the application
of any  payments  made or  property  transferred  by the  Trustees or upon their
order.

6. (a) The Trustees shall have no power to bind any Shareholder personally or to
call upon any  Shareholder  for the  payment  of any sum of money or  assessment
whatsoever  other than such as the Shareholder may at any time personally  agree
to pay by way of  subscription  to any Shares or  otherwise.  Every note,  bond,
contract  or  other  undertaking  issued  by or on  behalf  of the  Trust or the
Trustees  relating  to  the  Trust  shall  include  a  recitation  limiting  the
obligation  represented thereby to the Trust and its assets (but the omission of
such a recitation shall not operate to bind any Shareholder).

                  (b) Except as otherwise  provided in this Declaration of Trust
or the  By-Laws,  whenever  this  Declaration  of Trust calls for or permits any
action to be taken by the Trustees hereunder,  such action shall mean that taken
by the Board of Trustees by vote of the  majority of a quorum of Trustees as set
forth from time to time in the By-Laws of the Trust or as  required  pursuant to
the  provisions  of the  1940  Act and the  rules  and  regulations  promulgated
thereunder.

                  (c) The Trustees  shall  possess and exercise any and all such
additional  powers as are  reasonably  implied from the powers herein  contained
such as may be  necessary  or  convenient  in the  conduct  of any  business  or
enterprise of the Trust,  to do and perform  anything  necessary,  suitable,  or
proper for the  accomplishment of any of the purposes,  or the attainment of any
one or more of the objects, herein enumerated, or which shall at any time appear
conducive to or expedient for the protection or benefit of the Trust,  and to do
and perform all other acts or things  necessary  or  incidental  to the purposes
herein before set forth, or that may be deemed necessary by the Trustees.

                  (d)  The   Trustees   shall   have  the  power  to   determine
conclusively  whether any moneys,  securities,  or other properties of the Trust
property  are, for the purposes of this Trust,  to be  considered  as capital or
income  and in what  manner any  expenses  or  disbursements  are to be borne as
between  capital and income whether or not in the absence of this provision such
moneys,  securities,  or other properties would be regarded as capital or income
and  whether  or  not  in  the  absence  of  this  provision  such  expenses  or
disbursements would ordinarily be charged to capital or to income.

7. The By-Laws of the Trust may divide the Trustees  into classes and  prescribe
the tenure of office of the several classes, but no class shall be elected for a
period  shorter than that from the time of the election  following  the division
into classes until the next meeting of Shareholders.

8. The  Shareholders  shall have the right to inspect  the  records,  documents,
accounts  and books of the  Trust,  subject  to  reasonable  regulations  of the
Trustees,  not contrary to Massachusetts  law, as to whether and to what extent,
and at what times and places,  and under what conditions and  regulations,  such
right shall be exercised.

9. Any  Trustee,  or any officer  elected or appointed by the Trustees or by any
committee of the Trustees or by the Shareholders or otherwise, may be removed at
any time, with or without cause, in such lawful manner as may be provided in the
By-Laws of the Trust.

10. If the  By-Laws  so  provide,  the  Trustees  shall have power to hold their
meetings,  to have an office or offices and,  subject to the  provisions  of the
laws  of  Massachusetts,  to  keep  the  books  of the  Trust  outside  of  said
Commonwealth at such places as may from time to time be designated by them.

11.  Securities  held by the  Trust  shall be voted in person or by proxy by the
President or a  Vice-President,  or such officer or officers of the Trust as the
Trustees  shall  designate for the purpose,  or by a proxy or proxies  thereunto
duly  authorized  by the  Trustees,  except as otherwise  ordered by vote of the
holders of a majority of the Shares  outstanding and entitled to vote in respect
thereto.

12. (a)  Subject to the  provisions  of the 1940 Act,  any  Trustee,  officer or
employee,  individually,  or any  partnership  of which any Trustee,  officer or
employee  may be a  member,  or any  corporation  or  association  of which  any
Trustee, officer or employee may be an officer,  director,  trustee, employee or
stockholder,  may be a party to, or may be pecuniarily  or otherwise  interested
in, any  contract or  transaction  of the Trust,  and in the absence of fraud no
contract or other transaction shall be thereby affected or invalidated; provided
that in case a Trustee, or a partnership,  corporation or association of which a
Trustee is a member, officer,  director,  trustee, employee or stockholder is so
interested,  such  fact  shall be  disclosed  or shall  have  been  known to the
Trustees or a majority thereof; and any Trustee who is so interested,  or who is
also a  director,  officer,  trustee,  employee  or  stockholder  of such  other
corporation or association or a member of such other  corporation or association
or a member  of such  partnership  which is so  interested,  may be  counted  in
determining the existence of a quorum at any meeting of the Trustees which shall
authorize  any such contract or  transaction,  and may vote thereat to authorize
any such contract or  transaction,  with like force and effect as if he were not
such director,  officer, trustee, employee or stockholder of such other trust or
corporation or association or a member of a partnership so interested.

                  (b) Specifically, but without limitation of the foregoing, the
Trust  may  enter  into  a  management  or  investment   advisory   contract  or
underwriting  contract and other  contracts  with, and may otherwise do business
with any manager or  investment  adviser  and/or any  sub-adviser  for the Trust
and/or  principal  underwriter  of the Shares of the Trust or any  subsidiary or
affiliate of any such manager or investment  adviser and/or  sub-adviser  and/or
principal  underwriter and may permit any such firm or corporation to enter into
any contracts or other arrangements with any other firm or corporation  relating
to the Trust notwithstanding that the Board of the Trust may be composed in part
of partners,  directors, officers or employees of any such firm or corporations,
and officers of the Trust may have been or may be or become partners, directors,
officers or  employees  of any such firm or  corporation,  and in the absence of
fraud  the  Trust and any such firm or  corporation  may deal  freely  with each
other,  and no such contract or transaction  between the Trust and any such firm
or corporation  shall be invalidated or in any way affected  thereby,  nor shall
any Trustee or officer of the Trust be liable to the Trust or to any Shareholder
or creditor  thereof or to any other  person for any loss  incurred by it or him
solely  because of the existence of any such contract or  transaction;  provided
that nothing  herein shall  protect any Trustee or officer of the Trust  against
any  liability  to the  Trust  or to its  security  holders  to  which  he would
otherwise  be  subject  by reason  or  willful  misfeasance,  bad  faith,  gross
negligence  or reckless  disregard of the duties  involved in the conduct of his
office.

                  (c) (1) The Trust  shall  indemnify  all  current  and  former
trustees, officers, employees and agents of the Trust (each, a "Covered Person")
against  judgments,  fines,  settlements  and  expenses  to the  fullest  extent
authorized, and in the manner permitted, by applicable federal and state law.

                      (2) The Trust shall  advance  the  expenses of Covered
Persons who are parties to any Proceeding to the fullest extent authorized,  and
in the manner  permitted,  by applicable  federal and state law. For purposes of
this paragraph,  "Proceeding" means any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative, or investigative.
(3) Pursuant and subject to  paragraphs  (1) and (2), the Trust shall  indemnify
each Covered Person against,  or advance the expenses of any Covered Person for,
the  amount  of any  deductible  provided  in  any  liability  insurance  policy
maintained by the Trust.

         13. (a) The term "Net Asset Value" of any Series shall mean that amount
by which the assets of that series exceed its liabilities,  all as determined by
or under the  direction  of the  Trustees.  Net Asset  Value per Share  shall be
determined  separately for each Series of Shares and shall be determined on such
days and at such times as the Trustees may determine.  Such determination may be
made on a Series-by-Series  or Class-by-Class  basis, as appropriate,  and shall
include any expenses  allocated to a specific Series or Class. The determination
shall be made with respect to securities for which market quotations are readily
available  at the market  value of such  securities;  and with  respect to other
securities  and  assets,  at the fair value as  determined  in good faith by the
Trustees,  provided,  however, that the Trustees,  without Shareholder approval,
may alter the method of  appraising  portfolio  securities  insofar as permitted
under  the 1940  Act and the  rules,  regulations  and  interpretations  thereof
promulgated  or issued by the Commission or insofar as permitted by any order of
the Commission  applicable to the Series. The Trustees may delegate any of their
powers and duties  under this  paragraph  13 with respect to appraisal of assets
and  liabilities.  At any time the  Trustees  may cause the Net Asset  Value per
Share last determined to be determined again in a similar manner and may fix the
time when such redetermined values shall become effective.

(a) Payment of the net asset value of Shares of the Trust  properly  surrendered
to it for  redemption  shall be made by the Trust within seven days after tender
of such  Shares to the Trust for such  purpose  plus any  period of time  during
which the right of the  holders of the shares of the Trust to require  the Trust
to redeem  such  shares  has been  suspended.  Any such  payment  may be made in
portfolio  securities  of the Trust and/or in cash,  as the Trustees  shall deem
advisable,  and no Shareholder  shall have a right,  other than as determined by
the Trustees, to have his Shares redeemed in kind.

                           EIGHTH:

1. In case any Shareholder or former  Shareholder shall be held to be personally
liable  solely  by reason of his  being or  having  been a  Shareholder  and not
because of his acts or omissions or for some other reason,  the  Shareholder  or
former  Shareholder  (or his heirs,  executors,  administrators  or other  legal
representatives  or in the case of a corporation or other entity,  its corporate
or other general successor) shall be entitled out of the Trust estate to be held
harmless  from and  indemnified  against all loss and expense  arising from such
liability. This Trust shall, upon request by the Shareholder, assume the defense
of any claim made against any Shareholder for any act or obligation of the Trust
and satisfy any judgment thereon.

2. It is hereby expressly declared that a trust and not a partnership is created
hereby.  No Trustee hereunder shall have any power to bind personally either the
Trust's  officers  or  any  Shareholder.   All  persons   extending  credit  to,
contracting  with or having any claim  against the Trust or the  Trustees  shall
look only to the assets of the Trust for payment under such credit,  contract or
claim; and neither the  Shareholders nor the Trustees,  nor any of their agents,
whether past, present or future, shall be personally liable therefor. Nothing in
this Declaration of Trust shall protect a Trustee against any liability to which
such Trustee would  otherwise be subject by reason of willful  misfeasance,  bad
faith,  gross  negligence  or reckless  disregard of the duties  involved in the
conduct of the office of Trustee hereunder.

3. The exercise by the Trustees of their powers and discretion hereunder in good
faith and with reasonable care under the circumstances then prevailing, shall be
binding upon everyone  interested.  Subject to the  provisions of paragraph 2 of
this Article EIGHTH,  the Trustees shall not be liable for errors of judgment or
mistakes  of fact or law.  The  Trustees  may take  advice of  counsel  or other
experts with respect to the meaning and operation of this  Declaration of Trust,
and the subject to the provisions of paragraph 2 of this Article  EIGHTH,  shall
be under no liability for any act or omission in accordance  with such advice or
for failing to follow such advice.  The  Trustees  shall not be required to give
any bond as such,  nor any surety if a bond is  required.  4. This  Trust  shall
continue   without   limitation  of  time  but  subject  to  the  provisions  of
sub-sections (a), (b) and (c) of this paragraph 4.

(a) The Trustees, with the favorable vote of the holders of more than 50% of the
outstanding  Shares entitled to vote may sell and convey the assets of the Trust
(which  sale may be  subject  to the  retention  of assets  for the  payment  of
liabilities and expenses) to another issuer for a consideration  which may be or
include  securities  of such issuer.  Upon making  provision  for the payment of
liabilities,  by  assumption  by such issuer or  otherwise,  the Trustees  shall
distribute the remaining proceeds ratably among the holders of the Shares of the
Trust then outstanding.

(b) The Trustees, with the favorable vote of the holders of more than 50% of the
outstanding Shares entitled to vote, may at any time sell and convert into money
all the  assets of the  Trust.  Upon  making  provision  for the  payment of all
outstanding obligations, taxes and other liabilities,  accrued or contingent, of
the Trust,  the Trustees  shall  distribute  the  remaining  assets of the Trust
ratably among the holders of the outstanding Shares.

(c)  Upon  completion  or the  distribution  of the  remaining  proceeds  or the
remaining  assets as  provided  in  sub-sections  (a) and (b),  the Trust  shall
terminate  and  the  Trustees  shall  be  discharged  of  any  and  all  further
liabilities  and duties  hereunder  and the  right,  title and  interest  of all
parties shall be canceled and discharged.

5. The original or a copy of this  instrument  and of each  declaration of trust
supplemental  hereto  shall be kept at the  office of the Trust  where it may be
inspected by any Shareholder. A copy of this instrument and of each Supplemental
Declaration of Trust shall be filed with the  Massachusetts  Secretary of State,
as well as any other governmental office where such filing may from time to time
be  required.  Anyone  dealing  with the Trust may rely on a  certificate  by an
officer of the Trust as to whether or not any such Supplemental  Declarations of
Trust  have  been  made and as to any  matters  in  connection  with  the  Trust
hereunder,  and with the same effect as if it were the  original,  may rely on a
copy certified by an officer of the Trust to be a copy of this  instrument or of
any such  Supplemental  Declaration of Trust.  In this instrument or in any such
Supplemental  Declaration  of  Trust,  references  to this  instrument,  and all
expressions like "herein,"  "hereof" and "hereunder" shall be deemed to refer to
this instrument as amended or affected by any such  Supplemental  Declaration of
Trust.  This instrument may be executed in any number of  counterparts,  each of
which shall be deemed an original.

6. The trust set forth in this instrument is created under and is to be governed
by and construed and  administered  according to the laws of the Commonwealth of
Massachusetts.  The Trust shall be of the type commonly  called a  Massachusetts
business  trust,  and without  limiting  the  provisions  hereof,  the Trust may
exercise all powers which are ordinarily exercised by such a trust.

7. The Board of Trustees is empowered to cause the redemption of the Shares held
in any account in the aggregate net asset value of such Shares (taken at cost or
value,  as determined by the Board) has been reduced by a Shareholder to $500 or
less upon such notice to the  Shareholders in question,  with such permission to
increase the  investment in question and upon such other terms and conditions as
may be fixed by the Board of Trustees in accordance with the 1940 Act.

8. In the event that any person  advances  the  organizational  expenses  of the
Trust,  such  advances  shall become an  obligation of the Trust subject to such
terms and  conditions  as may be fixed by, and on a date fixed by, or determined
in accordance with criteria fixed by the Board of Trustees, to be amortized over
a period or periods to be fixed by the Board.

9.  Whenever  any action is taken  under  this  Declaration  of Trust  under any
authorization  to take action which is  permitted  by the 1940 Act,  such action
shall be deemed to have been properly taken if such action is in accordance with
the  construction  of the 1940 Act then in effect as  expressed  in "no  action"
letters of the staff of the Commission or any release, rule, regulation or order
under  the  1940  Act or any  decision  of a court  of  competent  jurisdiction,
notwithstanding  that any of the foregoing shall later be found to be invalid or
otherwise reversed or modified by any of the foregoing.

10.  Any  action  which  may be  taken  by the  Board  of  Trustees  under  this
Declaration of Trust or its By-Laws may be taken by the  description  thereof in
the then effective prospectus or Statement of Additional Information relating to
the Shares  under the  Securities  Act of 1933 or in any proxy  statement of the
Trust rather than by formal resolution of the Board.

11. Whenever under this Declaration of Trust, the Board of Trustees is permitted
or  required  to  place a value on  assets  of the  Trust,  such  action  may be
delegated  by  the  Board,  and/or  determined  in  accordance  with  a  formula
determined by the Board, to the extent permitted by the 1940 Act.

12. If  authorized  by the vote of the  Trustees,  the  Trustees  shall amend or
otherwise  supplement  this  instrument,   by  making  a  Declaration  of  Trust
supplemental  hereto,  which  thereafter  shall  form a part  hereof;  any  such
Supplemental  Declaration of Trust may be executed by and on behalf of the Trust
and the Trustees by any officer or officers of the Trust. A restated Declaration
of Trust,  integrating  into an single  instrument  all of the provisions of the
Declaration  of Trust  which are then in effect and  operative,  may be executed
from time to time by a majority of the Trustees.  Notwithstanding  the forgoing,
no amendment  that would have a material  adverse  impact upon the rights of the
shareholders  may be made without the favorable vote of the holders of more than
50% of the outstanding  Shares entitled to vote, or by any larger vote which may
be required by applicable law in a particular case.

         NINTH:  The resident agent for the Trust in the Commonwealth of
Massachusetts shall be: Prentice Hall Corporation System, Inc., 84 State Street,
Boston, MA 02109.

         IN WITNESS WHEREOF,  the undersigned,  being all of the Trustees of the
Trust,  have executed this Amended and Restated  Declaration  of Trust as of the

                                RESTATED BY-LAWS

                              As of March 24, 2000

                                    ARTICLE I

                                  SHAREHOLDERS

         Section 1. Place of Meeting.  All meetings of the  Shareholders  (which
      term as used herein  shall,  together  with all other terms defined in the
      Declaration  of Trust,  have the same  meaning  as in the  Declaration  of
      Trust) shall be held at the principal office of the Trust or at such other
      place as may from time to time be  designated by the Board of Trustees and
      stated in the notice of meeting.

         Section 2. Calling of Meetings.  Meetings of the  Shareholders  for any
      purpose or purposes  (including the election of Trustees) may be called by
      the Chairman of the Board of Trustees,  if any, or by the  President or by
      the Board of Trustees and shall be called by the Secretary upon receipt of
      the  request  in  writing  signed by  Shareholders  holding  not less than
      one-third in amount of the entire number of Shares issued and  outstanding
      and  entitled to vote  thereat.  Such  request  shall state the purpose or
      purposes of the proposed meeting.

         Section  3.  Notice of  Meetings.  Not less than ten days' and not more
      than  ninety  days'  written  or  printed   notice  of  every  meeting  of
      Shareholders,  stating the time and place thereof (and the general  nature
      of the business  proposed to be transacted at any special or extraordinary
      meeting),  shall be given to each Shareholder  entitled to vote thereat by
      leaving the same with him or at his  residence  or usual place of business
      or by mailing it,  postage  prepaid and addressed to him at his address as
      it appears upon the books of the Trust.

         No notice of the time,  place or purpose of any meeting of Shareholders
      need be given to any  Shareholder  who attends in person or by proxy or to
      any Shareholder who, in writing executed and filed with the records of the
      meeting, either before or after the holding thereof, waives such notice.

         Section 4. Record Dates.  The Board of Trustees may fix, in advance,  a
      date,  not exceeding  ninety days and not less than ten days preceding the
      date of any  meeting  of  Shareholders,  and  not  exceeding  ninety  days
      preceding  any  dividend  payment  date or any date for the  allotment  of
      rights,  as a  record  date  for  the  determination  of the  Shareholders
      entitled to receive such dividends or rights, as the case may be; and only
      Shareholders  of record on such date shall be entitled to notice of and to
      vote at such meeting or to receive such  dividends or rights,  as the case
      may be.

         Section 5. Quorum,  Adjournment of Meetings.  The presence in person or
      by proxy of the holders of record of  one-third of the Shares of the stock
      of the Trust issued and  outstanding  and entitled to vote thereat,  shall
      constitute a quorum at all meetings of the Shareholders. If at any meeting
      of the  Shareholders  there  shall  be less  than a  quorum  present,  the
      Shareholders present at such meeting may, without further notice,  adjourn
      the same from time to time until a quorum  shall  attend,  but no business
      shall be transacted  at any such  adjourned  meeting  except such as might
      have been lawfully transacted had the meeting not been adjourned.

         Section 6. Voting and Inspectors. At all meetings of Shareholders every
      Shareholder  of record  entitled to vote thereat shall be entitled to vote
      at such meeting  either in person or by proxy  appointed by  instrument in
      writing   subscribed   by  such   Shareholder   or  his  duly   authorized
      attorney-in-fact.

         All elections of Trustees shall be had by a plurality of the votes cast
      and all  questions  shall be decided by a majority of the votes  cast,  in
      each case at a duly constituted  meeting,  except as otherwise provided in
      the  Declaration  of Trust or in these  By-Laws or by  specific  statutory
      provision  superseding the restrictions  and limitations  contained in the
      Declaration of Trust or in these By-Laws.

         At any election of Trustees,  the Board of Trustees  prior thereto may,
      or, if they have not so acted,  the  Chairman of the meeting may, and upon
      the request of the  holders of ten per cent (1 0%) of the Shares  entitled
      to vote at such  election  shall,  appoint two  inspectors of election who
      shall first  subscribe an oath of  affirmation  to execute  faithfully the
      duties  of  inspectors  at such  election  with  strict  impartiality  and
      according to the best of their ability,  and shall after the election make
      a certificate of the result of the vote taken. No candidate for the office
      of Trustee shall be appointed such inspector.

         The Chairman of the meeting may cause a vote by ballot to be taken upon
      any  election or matter,  and such vote shall be taken upon the request of
      the  holders of ten per cent (10%) of the Shares  entitled to vote on such
      election or matter.

         Section 7.  Conduct of  Shareholders'  Meetings.  The  meetings  of the
      Shareholders  shall  be  presided  over by the  Chairman  of the  Board of
      Trustees,  if any, or if he shall not be present, by the President,  or if
      he shall not be present,  by a Vice-President,  or if neither the Chairman
      of the Board of Trustees, the President nor any Vice-President is present,
      by a chairman to be elected at the meeting. The Secretary of the Trust, if
      present, shall act as Secretary of such meetings, or if he is not present,
      an  Assistant  Secretary  shall so act;  if neither the  Secretary  nor an
      Assistant  Secretary  is  present,   then  the  meeting  shall  elect  its
      secretary.

         Section 8.  Concerning  Validity  of  Proxies,  Ballots,  Etc. At every
      meeting of the  Shareholders,  all proxies  shall be received and taken in
      charge of and all ballots shall be received and canvassed by the secretary
      of the meeting,  who shall decide all questions touching the qualification
      of voters, the validity of the proxies, and the acceptance or rejection of
      votes, unless inspectors of election shall have been appointed as provided
      in Section 6, in which event such  inspectors of election shall decide all
      such questions.

                                   ARTICLE II

                                BOARD OF TRUSTEES

         Section 1. Number of Tenure of Office. The business and property of the
      Trust shall be conducted and managed by a Board of Trustees  consisting of
      nine (9)  persons,  which number may be increased or decreased as provided
      in Section 2 of this Article.  The Board of Trustees may sit and alter the
      terms of office of the Trustees, may lengthen or lessen their own terms or
      make their  terms of  indefinite  duration,  all  subject to the 1940 Act.
      Trustees need not be  Shareholders.  No one shall  continue to serve as an
      independent  Trustee  after  the end of the  calendar  year in which  that
      person achieves the age of seventy-five (75).

         Section 2.  Increase or Decrease in Number of  Trustees;  Removal.  The
      Board of  Trustees  may  increase  the number of  Trustees to a number not
      exceeding fifteen, and may elect Trustees to fill the vacancies created by
      any such  increase in the number of  Trustees;  the Board of Trustees  may
      likewise  decrease the number of Trustees to a number not less than three.
      Vacancies  occurring  other than by reason of any such  increase  shall be
      filled as provided for a Massachusetts business corporation.  In the event
      that after proxy  material has been printed for a meeting of  Shareholders
      at which  Trustees are to be elected any one or more  management  nominees
      dies or becomes incapacitated,  the authorized number of Trustees shall be
      automatically reduced by the number of such nominees,  unless the Board of
      Trustees prior to the meeting shall  otherwise  determine.  Any Trustee at
      any time may be removed  either with or without cause by  resolution  duly
      adopted by the  affirmative  votes of the  holders of the  majority of the
      Shares  of the Trust  present  in  person  or by proxy at any  meeting  of
      Shareholders  at which such vote may be taken,  provided  that a quorum is
      present,  or by such larger vote as may be required by Massachusetts  law.
      Any  Trustee  at any time may be  removed  for  cause by  resolution  duly
      adopted  at any  meeting of the Board of  Trustees  provided  that  notice
      thereof  is  contained  in the  notice  of  such  meeting  and  that  such
      resolution  is adopted by the vote of at least two thirds of the  Trustees
      whose removal is not proposed.  As used herein, "for cause" shall mean any
      cause which under  Massachusetts law would permit the removal of a Trustee
      of a business trust.

         Section 3. Place of Meeting. The Trustees may hold their meetings, have
      one  or  more   offices,   and  keep  the  books  of  the  Trust   outside
      Massachusetts, at any office or offices of the Trust or at any other place
      as they may from time to time by resolution determine,  or, in the case of
      meetings,  as they may from  time to time by  resolution  determine  or as
      shall be specified or fixed in the respective notices or waivers of notice
      thereof.

         Section 4.  Regular  Meetings.  Regular  meetings of the Board of
      Trustees  shall be held at such time and on such notice, if any, as the
      Trustees may from time to time determine.

         Section 5. Special Meetings.  Special meetings of the Board of Trustees
      may be held from time to time  upon call of the  Chairman  of the Board of
      Trustees, if any, the President or two or more of the Trustees, by oral or
      telegraphic  or written  notice  duly  served on or sent or mailed to each
      Trustee not less than one day before such meeting. No notice need be given
      to any Trustee  who  attends in person or to any  Trustee  who, in writing
      executed and filed with the records of the meeting  either before or after
      the holding thereof,  waives such notice.  Such notice or waiver of notice
      need not state the purpose or purposes of such meeting.

         Section 6.  Quorum.  One-third  of the  Trustees  then in office  shall
      constitute  a quorum for the  transaction  of  business,  provided  that a
      quorum  shall in no case be less than two  Trustees.  If at any meeting of
      the Board there shall be less than a quorum  present (in person or by open
      telephone  line,  to the extent  permitted by the 1940 Act), a majority of
      those  present may  adjourn  the meeting  from time to time until a quorum
      shall have been obtained.  The act of the majority of the Trustees present
      at any meeting at which  there is a quorum  shall be the act of the Board,
      except  as may be  otherwise  specifically  provided  by  statute,  by the
      Declaration of Trust or by these By-Laws.

         Section 7.  Executive  Committee.  The Board of  Trustees  may,  by the
      affirmative  vote of a  majority  of the  entire  Board,  elect  from  the
      Trustees an  Executive  Committee to consist of such number of Trustees as
      the Board may from time to time  determine.  The Board of Trustees by such
      affirmative  vote shall  have  power at any time to change the  members of
      such  Committee  and may fill  vacancies in the Committee by election from
      the Trustees.  When the Board of Trustees is not in session, the Executive
      Committee  shall  have and may  exercise  any or all of the  powers of the
      Board of Trustees in the  management  of the  business  and affairs of the
      Trust  (including  the  power to  authorize  the  seal of the  Trust to be
      affixed to all papers  which may require it) except as provided by law and
      except the power to increase or decrease the size of, or fill vacancies on
      the Board. The Executive Committee may fix its own rules of procedure, and
      may meet, when and as provided by such rules or by resolution of the Board
      of  Trustees,  but in  every  case the  presence  of a  majority  shall be
      necessary  to  constitute  a quorum.  In the  absence of any member of the
      Executive Committee the members thereof present at any meeting, whether or
      not they  constitute  a  quorum,  may  appoint  a member  of the  Board of
      Trustees to act in the place of such absent member.

         Section 8. Other Committees.  The Board of Trustees, by the affirmative
      vote of a majority of the entire Board, may appoint other committees which
      shall in each case  consist of such  number of members  and shall have and
      may  exercise  such powers as the Board may  determine  in the  resolution
      appointing  them.  A majority  of all  members of any such  committee  may
      determine its action,  and fix the time and place of its meetings,  unless
      the Board of Trustees shall otherwise provide. The Board of Trustees shall
      have  power at any time to  change  the  members  and  powers  of any such
      committee, to fill vacancies, and to discharge any such committee.

         Section 9. Informal  Action by and  Telephone  Meetings of Trustees and
      Committees. Any action required or permitted to be taken at any meeting of
      the Board of Trustees  or any  committee  thereof  may be taken  without a
      meeting,  if a written  consent to such action is signed by all members of
      the Board, or of such  committee,  as the case may be. Trustees or members
      of a committee  of the Board of Trustees may  participate  in a meeting by
      means of a conference telephone or similar communications  equipment; such
      participation  shall,  except as otherwise  required by the 1940 Act, have
      the same effect as presence in person.

         Section 10.  Compensation  of Trustees.  Trustees  shall be entitled to
      receive such  compensation  from the Trust for their  services as may from
      time to time be voted by the Board of Trustees.

         Section 11. Dividends. Dividends or distributions payable on the Shares
      may, but need not be,  declared by specific  resolution of the Board as to
      each dividend or distribution;  in lieu of such specific resolutions,  the
      Board may,  by general  resolution,  determine  the method of  computation
      thereof,  the method of  determining  the  Shareholders  to which they are
      payable and the methods of determining  whether and to which  Shareholders
      they are to be paid in cash or in additional Shares.

                                   ARTICLE III

                                    OFFICERS

         Section 1.  Executive  Officers.  The  executive  officers of the Trust
      shall be chosen by the Board of Trustees.  These may include a Chairman of
      the Board of Trustees,  and shall  include a President,  a Secretary and a
      Treasurer.  The  Chairman  of the  Board  of  Trustees,  if any,  shall be
      selected  from among the  Trustees.  The Board of Trustees may also in its
      discretion  appoint one or more  Vice-Presidents,  Assistant  Secretaries,
      Assistant Treasurers, (the number thereof to be determined by the Board of
      Trustees) and other  officers,  agents and employees,  who shall have such
      authority and perform such duties as the Board or the Executive  Committee
      may determine.  The Board of Trustees may fill any vacancy which may occur
      in  any  office.   Any  two  offices,   except  those  of  President   and
      Vice-President,  may be held by the  same  person,  but no  officer  shall
      execute,  acknowledge  or verify any instrument in more than one capacity,
      if such  instrument is required by law or by these By-Laws to be executed,
      acknowledged or verified by two or more officers.

         Section 2. Term of Office.  The term of office of all officers shall be
      as fixed by the Board of  Trustees;  however,  any  officer may be removed
      from office at any time with or without cause by the vote of a majority of
      the entire Board of Trustees.

         Section 3. Powers and Duties. The officers of the Trust shall have such
      powers and duties as generally  pertain to their  respective  offices,  as
      well as such  posers and duties as may from time to time be  conferred  by
      the Board of Trustees or the Executive Committee.

                           THE PARNASSUS INCOME TRUST

                          INVESTMENT ADVISORY AGREEMENT

         AGREEMENT  made  this  24th day of  March,  2000,  by and  between  THE
PARNASSUS  INCOME TRUST (the  "Trust"),  a  Massachusetts  business  trust,  and
PARNASSUS INVESTMENTS (the "Adviser").

                              W I T N E S S E T H :

         In consideration of the mutual promises and agreements herein contained
and  other  good and  valuable  consideration,  the  receipt  of which is hereby
acknowledged, it is hereby agreed by and between the parties hereto as follows:

     1.  In General

         The  Adviser  agrees,  all as more  fully set forth  herein,  to act as
         managerial  investment  adviser  to  the  Trust  with  respect  to  the
         investment  of its assets and to supervise and arrange the purchase and
         sale of  securities  held in the  portfolio of the Trust and  generally
         administer the affairs of the Trust.

     2.  Duties and Obligation of the Adviser with respect to Management of the
         Trust

         (a)      Subject  to the  succeeding  provisions  of this  section  and
                  subject to the  direction and control of the Board of Trustees
                  of the Trust, the Adviser shall:

                  (i) Decide what securities shall be purchased or sold by the
                      Trust and when; and

                  (ii)Arrange for the purchase and the sale of  securities  held
                      in the portfolio of the Trust by placing purchase and sale
                      orders for the Trust.

         (b)      Any investment purchases or sales made by the Adviser shall at
                  all  times  conform  to,  and  be  in  accordance   with,  any
                  requirements  imposed by: (1) the provisions of the Investment
                  Company   Act  of  1940  (the  "Act")  and  of  any  rules  or
                  regulations  in force  thereunder;  (2) any  other  applicable
                  provisions of law; (3) the  provisions of the  Declaration  of
                  Trust and  By-Laws of the Trust as amended  from time to time;
                  (5) any policies  and  fundamental  policies of the Trust,  as
                  reflected in its  registration  statement under the Act, or as
                  amended by the shareholders of the Trust.

         (c)      The  Adviser  shall also  administer  the affairs of the Trust
                  and, in connection  therewith,  shall be  responsible  for (i)
                  maintaining   the  Trust's  books  and  records   (other  than
                  financial  or  accounting  books and  records  or those  being
                  maintained  by  the  Trust's  custodian,   transfer  agent  or
                  accounting   services  agent);  (ii)  overseeing  the  Trust's
                  insurance relationships;

                  The  Adviser  shall  give the  Trust the  benefit  of its best
                  judgement and effort in rendering services thereunder, but the
                  Adviser  shall not be liable for any loss  sustained by reason
                  of the purchase, sale or retention of any security, whether or
                  not such  purchase,  sale or  retention  shall have been based
                  upon its own investigation and research or upon  investigation
                  and   research   made  by  any  other   individual,   firm  or
                  corporation,  if such purchase,  sale or retention  shall have
                  been made and such other individual, firm or corporation shall
                  have been selected in good faith.  Nothing  contained  therein
                  shall,  however,  be construed to protect the Adviser  against
                  any  liability to the Trust or its security  holders 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 this Agreement.

                  The  Trust  agrees  that the word  "Parnassus"  in its name is
                  derived  from the name of the Adviser  and is the  property of
                  the Adviser for  copyright  and all other  purposes  and that,
                  therefore,  such word may be freely  used by the Adviser as to
                  other investment companies or other investment  products.  The
                  Trust  further  agrees  that,  in the event  that the  Adviser
                  ceases to be the  Trust's  investment  adviser for any reason,
                  the Trust will  (unless  the  Adviser  otherwise  consents  in
                  writing)  promptly take all necessary steps to change its name
                  to a name not including the word "Parnassus".

                  It is agreed that the Adviser shall have no  responsibility or
                  liability  for the  accuracy  or  completeness  of the Trust's
                  Registration  Statement  under the 1940 Act or the  Securities
                  Act of 1933 except for information supplied by the Adviser for
                  inclusion  therein.  The Trust agrees to indemnify the Adviser
                  to the full extent  permitted  by the Trust's  Declaration  of
                  Trust.

     3.  Broker-Dealer Relationships

                  In connection with its duties set forth in Section 2(a)(ii) of
         this  Agreement to arrange for the purchase and the sale of  securities
         held in the portfolio of the Trust by placing  purchase and sale orders
         for the Trust, the Adviser shall select such broker-dealers ("brokers")
         as shall, in the Adviser's judgment,  implement the policy of the Trust
         to achieve "best execution", i.e. prompt and efficient execution at the
         most favorable securities price. In making such selection,  the Adviser
         is  authorized  to consider the  reliability,  integrity  and financial
         condition of the broker.

                  The Adviser is also authorized to consider  whether the broker
         provides  brokerage and/or research  services to the Trust and/or other
         accounts of the Adviser.  The  commissions  paid to such brokers may be
         higher  than  another  broker  would  have  charged  if  a  good  faith
         determination  is made by the Adviser that the commission is reasonable
         in relation to the  services  provided,  viewed in terms of either that
         particular transaction or the Adviser's overall discretion. The Adviser
         shall use its judgment in  determining  that the amount of  commissions
         paid are  reasonable in relation to the value of brokerage and research
         services  provided  and need not place or  attempt  to place a specific
         dollar  value on such  services or on the portion of  commission  rates
         reflecting such services.  To demonstrate that such determinations were
         in good faith and to show the  overall  reasonableness  of  commissions
         paid, the Adviser shall be prepared to show that  commissions  paid (i)
         were  for  purposes  contemplated  by this  Agreement;  (ii)  were  not
         allocated  or paid for  products  or  services  which were  readily and
         customarily  available and offered to the public on a commercial basis;
         and (iii)  were  within a  reasonable  range as  compared  to the rates
         charged by qualified brokers to other  institutional  investors as such
         rates may become known from available information. The Trust recognizes
         that, on any particular transaction, a higher than usual commission may
         be paid due to the  difficulty  of the  transaction  in  question.  The
         Adviser is also  authorized to consider  sales of shares as a factor in
         the   selection  of  brokers  to  execute   brokerage   and   principal
         transactions,  subject  to the  requirements  of  "best  execution"  as
         defined above.

     4.  Allocation of Expenses

                  The  Adviser  agrees that it will  furnish  the Trust,  at the
         Adviser's expense, with all office space and facilities,  and equipment
         and clerical personnel necessary for carrying out its duties under this
         Agreement.  The Adviser will also pay all compensation of all Trustees,
         officers and employees of the Trust who are  affiliated  persons of the
         Adviser.  All costs and expenses not  expressly  assumed by the Adviser
         under this  Agreement  shall be paid by the Trust,  including,  but not
         limited to (i) interest and taxes;  (ii) brokerage  commissions;  (iii)
         insurance  premiums;  (iv)  compensation  and  expenses of its Trustees
         other  than  those  affiliated  with the  Adviser;  (v) legal and audit
         expenses; (vi) fees and expenses of the Trust's custodian,  shareholder
         servicing  or  transfer  agent and  accounting  services  agent;  (vii)
         expenses  incident  to the  issuance  of its  shares,  including  stock
         certificates  and issuance of shares on the payment of, or reinvestment
         of,  dividends;  (viii) fees and expenses  incident to the registration
         under Federal or state securities laws of the Trust or its shares; (ix)
         expenses of  preparing,  printing  and mailing  reports and notices and
         proxy  material to  shareholders  of the Trust;  (x) all other expenses
         incidental to holding meetings of the Trust's  shareholders;  (xi) dues
         or assessments of or contributions to the Investment  Company Institute
         and the  Social  Investment  Forum or any  successor;  and  (xii)  such
         non-recurring expenses as may arise, including litigation affecting the
         Trust and the legal  obligations  which the Trust may have to indemnify
         its officers and Trustees with respect thereto.

5.       Compensation of the Adviser

         (a)      The Trust agrees to pay the Adviser and the Adviser  agrees to
                  accept as full  compensation for all services  rendered by the
                  Adviser  hereunder,  an annual  management fee payable monthly
                  and  computed  at the  following  annual  percentages  of each
                  Fund's average daily net assets: the Equity Income Fund, 0.75%
                  of the first $30  million,  0.70% of the next $70  million and
                  0.65% of the amount above $100 million.  For the  Fixed-Income
                  Fund and the California  Tax-Exempt  Fund, the fee is 0.50% of
                  the first $200  million,  0.45% of the next $200  million  and
                  0.40% of the amount above $400 million.

         (b)      In the event the expenses of the Trust (including the fees of
                  the  Adviser and amortization of organization expenses but
                  excluding interest, taxes, brokerage commissions,
                  extraordinary expenses and sales charges and distribution
                  fees) for any fiscal year exceed the limits set by applicable
                  regulations of state securities commissions, the Adviser will
                  reduce its fee by the amount of such excess. Any such
                  reductions are subject to readjustment during the year. The
                  payment of the management fee at the end of any month will be
                  reduced or postponed or, if necessary, a refund will be made
                  to the Trust so that at no time will there be any accrued but
                  unpaid liability under this expense limitation.

     6.  Duration and Termination

         (a)      This Agreement shall go into effect on the date set forth
                  above and shall, unless terminated as hereinafter provided,
                  continue in effect until April 30, 2001, and thereafter from
                  year to year, but only so long as such continuance is
                  specifically approved at least annually by the Trust's Board
                  of Trustees, including the vote of a majority of the Trustees
                  who are not parties to this Agreement or "interested persons"
                  (as defined in the Act) of any such party cast in person at a
                  meeting called for the purpose of voting on such approval, or
                  by the vote of the holders of a "majority" (as so defined) of
                  the outstanding voting securities of the Trust and by such a
                  vote of the Trustees.

(b)  This Agreement may be terminated by the Adviser at any time without penalty
     upon giving the Trust sixty (60) days' written  notice (which notice may be
     waived by the Trust) and may be terminated by the Trust at any time without
     penalty  upon giving the Adviser  sixty (60) days'  written  notice  (which
     notice may be waived by the Adviser), provided that such termination by the
     Trust  shall be  directed  or approved by the vote of a majority of all its
     Trustees  in office at the time or by the vote of the holders of a majority
     (as defined in the Act) of the voting  securities  of the Trust at the time
     outstanding  and  entitled  to vote.  This  Agreement  shall  automatically
     terminate in the event of its assignment (as so defined).

7.       No Shareholder Liability.

         The Adviser  understands that the obligations of this Agreement are not
         binding upon any shareholder of the Trust personally, but bind only the
         Trust's  property.  The  Adviser  represents  that it has notice of the
         provisions of the Trust's Declaration of Trust disclaiming  shareholder
         liability for acts or obligations of the Trust.

         IN WITNESS  WHEREOF,  the  parties  hereto  have  caused the  foregoing
instrument  to be  executed  by duly  authorized  persons  and their seals to be
hereunto affixed, all as of the day and year first above written.

PARNASSUS INCOME TRUST

                             DISTRIBUTION AGREEMENT

         This  Agreement,  made as of the 24th day of March,  2000,  between THE
PARNASSUS  INCOME TRUST,  a  Massachusetts  business  trust (the  "Trust"),  and
PARNASSUS INVESTMENTS, a California corporation (the "Distributor").

                                   WITNESSETH:

         Whereas,  the  Trust  proposes  to engage in  business  as an  open-end
management  investment  company and is registered  as such under the  Investment
Company Act of 1940,  as amended  (the "1940 Act") and it is in the  interest of
the Trust to offer its shares for sale continuously; and

         Whereas,  the  Distributor is registered as a  broker-dealer  under the
Securities Exchange Act of 1934, as amended (the "1934 Act"), and is a member in
good  standing of the National  Association  of  Securities  Dealers,  Inc. (the
"NASD"); and

         Whereas,  the Trust and the Distributor wish to enter into an agreement
with each other with respect to the continuous offering of the Trust's Shares of
Beneficial  Interest  (the  "Shares"),  no par  value,  to  commence  after  the
effectiveness  of its  initial  registration  statement  filed  pursuant  to the
Securities Act of 1933, as amended (the "1933 Act"), and the 1940 Act.

         Now, THEREFORE, the parties agree as follows:

         1.   Appointment  of   Distributor.   The  Trust  hereby  appoints  the
Distributor  as its  exclusive  agent to sell and to arrange for the sale of the
Trust's Shares, on the terms and for the period set forth in this Agreement, and
the  Distributor  hereby  accepts such  appointment  and agrees to act hereunder
directly  and/or  through the Trust's  transfer agent in the manner set forth in
the Prospectus (as defined below). It is understood and agreed that the services
of the Distributor  hereunder are not exclusive,  and the Distributor may act as
principal underwriter for the shares of any other registered investment company.

         2.  Services and Duties of the Distributor.
             --------------------------------------
             (a) The  Distributor  agrees to sell the  Shares,  as agent for the
Trust,  from  time to time  during  the term of this  Agreement  upon the  terms
described  in the  Trust's  Prospectus.  As  used in this  Agreement,  the  term
"Prospectus"  shall mean the prospectus and statement of additional  information
included as part of the Trust's Registration  Statement,  as such prospectus and
statement of additional  information may be amended or supplemented from time to
time,  and  the  term  "Registration  Statement"  shall  mean  the  Registration
Statement most recently filed from time to time by the Trust with the Securities
and Exchange  Commission  and effective  under the 1933 Act and the 1940 Act, as
such Registration  Statement is amended by any amendments thereto at the time in
effect.  The  Distributor  shall not be obligated to sell any certain  number of
Shares.

                  (b)  Upon   commencement  of  the  Trust's   operations,   the
Distributor  will hold itself  available to receive orders,  satisfactory to the
Distributor, for the purchase of the Shares and will accept such orders and will
transmit such orders and funds  received by it in payment for such Shares as are
so accepted to the Trust's  transfer  agent or  custodian,  as  appropriate,  as
promptly as practicable.  Purchase orders shall be deemed  effective at the time
and in the manner set forth in the Prospectus.  The  Distributor  shall not make
any short sales of Shares.

                  (c) The  offering  price of the shares  shall be the net asset
value (as defined in the Declaration of Trust of the Trust and determined as set
forth in the  Prospectus)  per share of the Shares.  The Trust shall furnish the
Distributor,  with all possible promptness, an advice of each computation of net
asset value.

         3.  Duties of the Trust.
             --------------------

                  (a) Maintenance of Federal  Registration.  The Trust shall, at
its  expense,  take,  from time to time,  all  necessary  action and such steps,
including  payment of the related  filing fees,  as may be necessary to register
and maintain  registration of a sufficient  number of Shares under the 1933 Act.
The Trust  agrees to file from time to time such  amendments,  reports and other
documents as may be necessary in order that there may be no untrue  statement of
a material fact in a registration statement or prospectus, or necessary in order
that  there may be no untrue  statement  of a  material  fact in a  registration
statement or prospectus,  or necessary in order that there may be no omission to
state a material fact in the registration statement or prospectus which omission
would make the statements therein misleading.

                  (b) Maintenance of "Blue Sky" Qualifications. The Trust shall,
at its expense,  use its best efforts to qualify and maintain the  qualification
of an appropriate  number of Shares for sale under the  securities  laws of such
states as the  Distributor  and the Trust may  approve,  and,  if  necessary  or
appropriate in connection  therewith,  to qualify and maintain the qualification
of the Trust as a broker or dealer in such states; provided that the Trust shall
not be required to amend its  Declaration of Trust or By-Laws to comply with the
laws of any state,  to maintain  an office in any state,  to change the terms of
the  offering  of the  Shares  in any  state  from the  terms  set  forth in its
Prospectus,  to qualify as a foreign  corporation  in any state or to consent to
service of process in any state other than with respect to claims arising out of
the  offering  and  sale of the  Shares.  The  Distributor  shall  furnish  such
information and other material  relating to its affairs and activities as may be
required by the Trust in connection with such qualifications.

                  (c) Copies of Reports and Prospectus.  The Trust shall, at its
expense,  keep the Distributor  fully informed with regard to its affairs and in
connection therewith shall furnish to the Distributor copies of all information,
financial  statements  and other papers  which the  Distributor  may  reasonably
request for use in connection with the  distribution  of Shares,  including such
reasonable  number of copies of its Prospectus and annual and interim reports as
the  Distributor  may  request and shall  cooperate  fully in the efforts of the
Distributor  to  sell  and  arrange  for  the  sale  of  the  Shares  and in the
performance of the Distributor under this Agreement.

         4.  Conformity with  Applicable Law and Rules.  The Distributor  agrees
that in selling Shares  hereunder it shall conform in all respects with the laws
of the United  State and of any state in which  Shares may be offered,  and with
applicable rules and regulations of the NASD.

         5.  Independent  Contractor.  In performing its duties  hereunder,  the
Distributor shall be an independent contractor and neither the Distributor,  nor
any of its officers, directors,  employees, or representatives is or shall be an
employee of the Trust in the performance of the Distributor's  duties hereunder.
The  Distributor  shall be responsible  for its own conduct and the  employment,
control,  and conduct of its agents and  employees and for injury to such agents
or  employees  or to others  through its agents or  employees.  The  Distributor
assumes  full  responsibility  for its agents  and  employees  under  applicable
statutes and agrees to pay all employee taxes thereunder.

         6.  Indemnification.
             ----------------

                  (a)  Indemnification  of  Trust.  The  Distributor  agrees  to
indemnify  and hold  harmless  the  Trust  and  each of its  present  or  former
trustees,  officers,  employees,  representatives  and each person,  if any, who
controls or previously  controlled the Trust within the meaning of Section 15 of
the 1933 Act against any and all losses, liabilities, damages,claims or expenses
(including the reasonable  costs or investigating or defending any alleged loss,
liability,  damage, claims or expense and reasonable legal counsel fees incurred
in  connection  therewith)  to which the  Trust or any such  person  may  become
subject  under  the 1933  Act,  under  any other  statute,  at  common  law,  or
otherwise,  arising out of the acquisition of any Shares by any person which (i)
may  be  based  upon  any  wrongful  act  by  the  Distributor  or  any  of  the
Distributor's directors, officers, employees or representatives,  or (ii) may be
based upon any untrue  statement or alleged untrue  statement of a material fact
contained in a registration statement,  prospectus,  shareholder report or other
information  covering  Shares filed or made public by the Trust or any amendment
thereof or  supplement  thereto,  or the  omission or alleged  omission to state
therein a material fact  required to be stated  therein or necessary to make the
statements  therein not  misleading  if such  statement  or omission was made in
reliance upon information furnished to the Trust by the Distributor.  In no case
(i) is  the  Distributor's  indemnity  in  favor  of the  Trust,  or any  person
indemnified to be deemed to protect the Trust or such indemnified person against
any  liability to which the Trust or such person  would  otherwise be subject by
reason of willful misfeasance, bad faith, or gross negligence in the performance
of his duties or by reason of his  reckless  disregard  of his  obligations  and
duties under this  Agreement or (ii) is the  Distributor  to be liable under its
indemnity  agreement  contained in this Paragraph with respect to any claim made
against the Trust or any person  indemnified unless the Trust or such person, as
the case may be,  shall have  notified the  Distributor  in writing of the claim
within a reasonable  time after the summons or other first written  notification
giving  information  of the nature of the claim  shall have been served upon the
Trust or upon such person (or after the Trust or such person shall have received
notice to such service on any designated agent). However,  failure to notify the
Distributor  of any such  claim  shall  not  relieve  the  Distributor  from any
liability which the Distributor may have to the Trust or any person against whom
such action is brought otherwise than on account of the Distributor's  indemnity
agreement contained in the Paragraph.

         The Distributor  shall be entitled to participate,  at its own expense,
in the defense,  or, if the Distributor so elects,  to assume the defense of any
suit brought to enforce any such claim, but, if the Distributor ejects to assume
the defense,  such defense  shall be  conducted by legal  counsel  chosen by the
Distributor and satisfactory to the Trust, to the persons indemnified  defendant
or defendants,  in the suit. In the event that the Distributor  elects to assume
the  defense of any such suit and  retain  such legal  counsel,  the Trust,  the
persons indemnified defendant or defendants in the suit, shall bear the fees and
expenses of any additional  legal counsel  retained by them. If the  Distributor
does not elect to assume  the  defense of any such suit,  the  Distributor  will
reimburse the Trust and the persons indemnified  defendant or defendants in such
suit for the reasonable fees and expenses of any legal counsel retained by them.
The Distributor  agrees to promptly notify the Trust of the  commencement of any
litigation  of  proceedings  against  it or any of its  officers,  employees  or
representatives in connection with the issue or sale of any Shares.

         (b)  Indemnification of the Distributor.  The Trust agrees to indemnify
and hold harmless the  Distributor  and each of its present or former  officers,
employees,  representatives  and each person, if any, who controls or previously
controlled  the  Distributor  within  the  meaning of Section 15 of the 1933 Act
against any and all losses, liabilities,  damages, claims or expenses (including
the reasonable costs of investigating or defending any alleged loss,  liability,
damage,  claim  or  expense  and  reasonable  legal  counsel  fees  incurred  in
connection  therewith)  to which the  Distributor  or and such person may become
subject  under  the 1933  Act,  under  any other  statute,  at  common  law,  or
otherwise,  arising out of the acquisition of any Shares by any person which (i)
may be based upon any wrongful act by the Trust or any of the Trust's  trustees,
officers,  employees  or  representatives,  or (ii) may be based upon any untrue
statement  or  alleged  untrue  statement  of a  material  fact  contained  in a
registration  statement,  prospectus,  shareholder  report or other  information
covering  Shares filed or made public by the Trust or any  amendment  thereof or
supplement  thereto,  or the  omission or alleged  omission  to state  therein a
material fact required to be stated  therein or necessary to make the statements
therein not  misleading  unless such  statement or omission was made in reliance
upon information  furnished to the Trust by the  Distributor.  In no case (i) is
the Trust's indemnity in favor of the Distributor,  or any person indemnified to
be deemed to protect the  Distributor  or such  indemnified  person  against any
liability to which the  Distributor or such person would otherwise be subject by
reason of willful misfeasance, bad faith, or gross negligence in the performance
of his duties or by reason of his  reckless  disregard  of his  obligations  and
duties  under  this  Agreement,  or (ii) is the  Trust to be  liable  under  its
indemnity  agreement  contained in this Paragraph with respect to any claim made
against  Distributor,  or person  indemnified  unless the  Distributor,  or such
person,  as the case may be,  shall  have  notified  the Trust in writing of the
claim  within a  reasonable  time  after  the  summons  or other  first  written
notification  giving  information  of the  nature of the claim  shall  have been
served upon the  Distributor  or upon such person (or after the  Distributor  or
such person shall have received notice of such service on any designated agent).
However,  failure to notify the Trust of any such claim  shall not  relieve  the
Trust  from any  liability  which the Trust may have to the  Distributor  or any
person  against  whom such  action is brought  otherwise  than on account of the
Trust's indemnity agreement contained in this Paragraph.

         The Trust shall be entitled to participate,  at its own expense, in the
defense,  or, if the Trust so elects,  to assume the defense of any suit brought
to enforce any such claim,  but if the Trust elects to assume the defense,  such
defense shall be conducted by legal counsel chosen by the Trust and satisfactory
to the Distributor,  to the persons indemnified defendant or defendants,  in the
suit.  In the event that the Trust elects to assume the defense of any such suit
and  retain  such  legal  counsel,  the  Distributor,  the  persons  indemnified
defendant  or  defendants  in the suit,  shall bear the fees and expenses of any
additional legal counsel retained by them. If the Trust does not elect to assume
the defense of any such suit, the Trust will reimburse the  Distributor  and the
persons indemnified defendant or defendants in such suit for the reasonable fees
and expenses of any legal counsel retained by them. The Trust agrees to promptly
notify the  Distributor  of the  commencement  of any  litigation or proceedings
against it or any of its trustees,  officers,  employees or  representatives  in
connection with the issue or sale of any Shares.

         7. Authorized Representations. The Distributor is not authorized by the
Trust  to  give  on  behalf  of  the  Trust  any  information  of  to  make  any
representations in connection with the sale of Shares other than the information
and  representations  contained in a registration  statement of prospectus filed
with the  Securities and Exchange  Commission  ("SEC") under the 1933 Act and/or
the 1940 Act, covering Shares, as such registration statement and prospectus may
be  amended or  supplemented  from time to time,  or  contained  in  shareholder
reports or other  material that may be prepared by or on behalf of the Trust for
the  Distributor's  use. This shall not be construed to prevent the  Distributor
from preparing and distributing tombstone advertisements and sales literature or
other material as it may deem  appropriate.  No person other than Distributor is
authorized to act as principal  underwriter (as such term is defined in the 1940
Act) for the Trust.

         8. Term of  Agreement.  The term of this  Agreement  shall begin on the
date first above written, and unless sooner terminated as hereinafter  provided,
this  Agreement  shall  remain in effect  from year to year so long as: (a) such
continuation  shall be  specifically  approved at least annually by the Board of
Trustees or by vote of a majority of the  outstanding  voting  securities of the
Trust and,  concurrently with such approval by the Board of Trustees or prior to
such approval by the holders of the outstanding  voting securities of the Trust,
as the case may be, by the vote,  cast in  person  at a meeting  called  for the
purpose of voting on such  approval,  of a majority of the trustees of the Trust
who are not parties to this  Agreement or interested  persons of any such party;
and (b) the Distributor shall not have notified the Trust, in writing,  at least
60 days  prior to April  30,  2001 or prior to April 30 of any year  thereafter,
that it does not desire such continuation.  The Distributor shall furnish to the
Trust,  promptly  upon  its  request,  such  information  as may  reasonably  be
necessary to evaluate the terms of this Agreement or any  extension,  renewal or
amendment hereof.

         9.       Amendment  and  Assignment of Agreement.  This  Agreement may
not be amended or assigned  without the affirmative  vote of a majority of the
outstanding  voting  securities of the Trust,  and this Agreement shall
automatically and immediately terminate in the event of its assignment.

         10.  Termination  of  Agreement.  This  Agreement  may be terminated by

Act of 1934 (the "1934 Act") and a member of the NASD (or any futures commission
merchant registered under the commodities  Exchange Act), relating to compliance
with  the  rules  of the  Options  Clearing  Corporation  and of any  registered
national  securities  exchange (or the Commodities Futures Trading Commission or
any  registered   contract   market),   or  of  any  similar   organization   or
organizations,  regarding  escrow  or  other  arrangements  in  connection  with
transactions  by the Fund,  (ii) for purposes of segregating  cash or government
securities in connection with options purchased,  sold or written by the Fund or
commodity  futures  contracts or options thereon  purchased or sold by the Fund,

Investment  Company Act Release No. 10666, or any subsequent release or releases
of the  Securities  and  Exchange  Commission  relating  to the  maintenance  of
segregated accounts by registered investment companies and (iv) for other proper
corporate purposes.

                  4.3 Confirmations and Statements.  Promptly after the close of
 business each day, the Bank shall make available to the Fund  information  with
 respect to all transfers to and from the account of each Portfolio  during that
 day.  The Bank need not send  written  confirmation  or a  summary  of all such
 transfers to or from the account of each Portfolio. Provided, however that upon
 the written  request the Fund, the Bank shall provide within 5 business days of
 such written request a copy of any confirmations which include  transactions of
 the Fund. Where  securities  purchased by a Portfolio are in a fungible bulk of
 Securities  registered in the name of the Bank (or its nominee) or shown on the
 Bank's  account on the books of the Depository or the  Book-Entry  System,  the
 Bank shall by book entry or otherwise identify the quantity of those securities
 belonging to such Portfolio.  At least monthly, the Bank shall furnish the Fund
 with a detailed  statement of the Securities and moneys held for each Portfolio
 under this Agreement.

                   4.4  Registration  of Securities and Physical  Separation All
 Securities  held for a Portfolio  which are issued or  issuable  only in bearer
 form,  except such  Securities as are held in the Book-Entry  System,  shall be
 held by the Bank in that form; all other Securities held for a Portfolio may be
 registered in the name of any duly appointed  registered nominee of the Bank as
 the Bank  may from  time to time  determine,  or in the name of the  Book-Entry
 System or the Depository or their successor or successors,  or their nominee or
 nominees.  When a reference is made in this  Agreement to an action to be taken
 by the  Bank it is  understood  by the  parties  that the  action  may be taken
 directly  or in the case of  book-entry  securities,  through  the  appropriate
 depository.  The Fund agrees to furnish to the Bank appropriate  instruments to
 enable the Bank to hold or deliver in proper form for transfer,  or to register
 in the name of its registered  nominee or in the name of the Book-Entry  System
 or the  Depository,  any  Securities  which it may hold  for the  account  of a
 Portfolio.  The Bank (or its  sub-custodians)  shall  hold all such  Securities
 specifically  allocated  to a  Portfolio  which are not held in the  Book-Entry
 System or the  Depository in a separate  account for such Portfolio in the name
 of such  Portfolio  and  physically  segregated  at all times from those of any
 other person or persons.

                  4.5   Collection  of  Income  and  Other   Matters   Affecting
 Securities.   Unless   otherwise   instructed   to  the   contrary  by  Written
 Instructions,  the  Bank  shall  with  respect  to all  Securities  held  for a
 Portfolio in accordance with this Agreement:

such income promptly on the contractual settlement date, whether or not actually
received,  to the account of the appropriate  Portfolio,  except for income from
foreign issues (which shall be collected as soon as reasonably  practicable  and
shall be credited when actually  received).  Income which has not been collected
after reasonable effort, within a time agreed upon between the parties, shall be
repaid to the Bank  pending  final  collection  at such date as may be  mutually
agreed upon by the Fund and the Bank.

                           4.5.2    Present for payment and collect the amount
payable upon all Securities which may mature or be called,  redeemed or retired,

the Fund of any call,  redemption or retirement  date with respect to securities
which  are  owned  by  a  Portfolio  and  held  by  the  Bank  or  its  nominee.
Notwithstanding the foregoing, the Bank shall have no responsibility to the Fund
or a  Portfolio  for  monitoring  or  ascertaining  of any call,  redemption  or
retirement  date with respect to  securities  which are owned by a Portfolio and
held by the Bank or its nominee.  Nor shall the Bank have any  responsibility or
liability  to the Fund or to a  Portfolio  for any loss by a  Portfolio  for any
missed  payment or other  default  resulting  therefrom  with respect to any put
security  owned by a Portfolio  and held by the Bank or its  nominee  unless the
Bank  received  timely  general  notification,  which  shall  not be less than 5
business days,  from the Fund or the Portfolio  specifying  the time,  place and
manner  for the  presentment  of any such put  security.  The Bank  shall not be

 10.     Concerning the Bank.
         --------------------

                  10.1  Standard of Conduct.  The Bank shall not be  responsible
 for the title,  validity or  genuineness  of any  property or evidence of title
 thereto  received  by it or  delivered  by it pursuant  to this  Agreement  and
 reasonably  believed by it to be valid or genuine and shall be held harmless in
 acting upon proper instructions,  resolutions,  any notice,  request,  consent,
 certificate or other instrument  reasonably believed by it to be genuine and to
 be signed by the proper  party or parties  and shall be  entitled to receive as
 conclusive  proof  of any  fact or  matter  required  to be  ascertained  by it
 hereunder  a  certificate  signed  by  the  President,  a Vice  President,  the
 Treasurer,  the Secretary or an Assistant  Secretary of the Fund.  The Bank may
 receive and accept a resolution as conclusive  evidence (a) of the authority of
 any  person  to  act  in  accordance   with  such  resolution  or  (b)  of  any
 determination  or of any  action  by the  Board  of  Trustees  pursuant  to the
 Declaration of Trust as described in such  resolution,  and such resolution may
 be  considered as in full force and effect until receipt by the Bank of written
 notice  from  the  Secretary  or an  Assistant  Secretary  of the  Fund  to the
 contrary.

       The Bank shall be  entitled to rely on and may act upon advice of counsel
 (who  may be  counsel  for the  Fund) on all  matters,  and  shall  be  without
 liability for any action  reasonably  taken or omitted pursuant to such advice.
 Provided,  however, that if such reliance involves a potential material loss to
 the Fund,  the Bank shall advise the Fund in advance and in writing of any such
 actions to be taken in accordance with such advice of counsel to the Bank.

       The Bank shall be held to the exercise of reasonable care in carrying out
 the provisions of this Agreement but shall be liable only for its own negligent
 or bad faith acts or willful  misconduct or willful failures to act by the Bank
 and its  agents  or  employees.  The  Bank  shall  have no  responsibility  for
 reviewing or questioning the acts or records of any prior  custodian.  The Fund
 shall  indemnify  the Bank and hold it  harmless  from and  against all losses,
 liabilities,  demands,  claims, actions,  expenses,  attorneys' fees, and taxes
 with respect to each Portfolio which the Bank may suffer or incur on account of
 being Custodian  hereunder except to the extent that such losses,  liabilities,
 demands,  claims,  actions,  expenses,  attorneys  fees or taxes arise from the
 Bank's own negligence or bad faith or willful  misconduct or willful failure to
 act.

       If the  Fund  requires  the  Bank to take  any  action  with  respect  to
 Securities of a Portfolio,  which action involves the payment of money or which
 action  may,  in the  opinion  of the Bank,  result in the Bank or its  nominee
 assigned to such  Portfolio  being liable for the payment of money or incurring
 liability of some other form, the Fund, as a prerequisite to requiring the Bank
 to take such  action,  shall,  prior to the Bank  taking such  action,  provide
 indemnity in writing to the Bank in an amount and form satisfactory to it.

       The Bank  shall  not be  liable  for any loss of data or any delay in its

 interruption in, loss of or malfunction in power, significant computer hardware
 or  systems  software  or  telephone  communication  service;  act of  civil or
 military  authority,  sabotage;  war or civil commotion;  fire;  explosion;  or
 strike (except that the Bank shall at all time be required to maintain  minimum
 critical activities).  The Bank shall use its best efforts to minimize any such
 loss or delay by all practical steps and to replace any lost data promptly. The

 of the Bank in making  computer time and its  personnel  available to input and
 process transactions hereunder when such a loss of data or delay occurs.

therefor;

Shares of any Portfolio, or the propriety of the amount to be paid therefor;

 representing the Fund's interest in the Book-Entry System or the Depository.

                  10.4 Collection Where Payment  Refused.  The Bank shall not be
 under any duty or obligation to take action to effect collection of any amount,
 if the  Securities  upon which such  amount is payable  are in  default,  or if
 payment is refused  after due demand or  presentation,  unless and until (a) it
 shall  be  directed  to take  such  action  by  Written  Instructions,  or Oral
 Instructions confirmed by Written Instructions,  and (b) it shall be assured to
 its  satisfaction of reimbursement of its costs and expenses in connection with
 any such action.

 owned  by any  Portfolio,  upon  terms  and  conditions  specified  in  Written
 Instructions,  or Oral Instructions confirmed by Written Instructions.  As such
 depository  or  sub-custodian  shall be  approved  in  advance  by the Board of
 Trustees of the Trust. The Custodians  shall remain  primarily  responsible for
 the Securities of the Fund held by any one depository or  sub-custodian  in the
 same manner as if held directly by the Custodian.

                  10.6     No Duty to Ascertain: Authority. The Bank shall not
be under any duty or obligation to ascertain  whether any Securities at any time
delivered  to or  held  by it for  the  Fund  and  specifically  allocated  to a
Portfolio  are such as may properly be held by the  Portfolio  and  specifically
allocated to such  Portfolio  under the  provisions of the  Declaration of Trust
arid the Fund's Prospectus.

                  10.7 Reliance on Certificates and Instructions. The Bank shall
 be entitled to rely upon any Written Instructions or Oral Instructions actually
 received by the Bank pursuant to the applicable  Sections of this Agreement and
 reasonably  believed by the Bank to be genuine and to be given by an Authorized
 Person.  The Fund agrees to forward to the Bank  Written  Instructions  from an
 Authorized Person confirming such Oral Instructions in such manner so that such
 Written Instructions are received by the Bank, whether by hand delivery, telex,
 or  otherwise,  by the  close  of  business  on the same  day  that  such  Oral
 Instructions  are given to the Bank.  The Fund  agrees  that the fact that such
 confirming instructions are not received by the Bank shall in no way affect the
 validity for the  transactions or  enforceability  of the  transactions  hereby
 authorized by the Fund.  The Fund agrees that the Bank shall incur no liability
 to the Fund in  acting  upon  Oral  Instructions  given  to the Bank  hereunder
 concerning such transactions  provided such  instructions  reasonably appear to

                                       of

                               THE PARNASSUS FUND

                           THE PARNASSUS INCOME TRUST

                                       and

                              PARNASSUS INVESTMENTS

         Adoption  of this  Code.  This Code of Ethics  (this  "Code")  has been
adopted by The Parnassus  Fund and The Parnassus  Income Trust (each of which is
referred  to as  the  "Fund")  and  Parnassus  Investments  (the  "Adviser")  in
compliance with Rule 17j-1 (the "Rule") under the Investment Company Act of 1940
(the "1940 Act").

         General  Principles.  In  their  personal  investment  activities,  all
Trustees  and  officers  of the Fund and all  officers,  directors  and staff of
Parnassus   Investments  should  at  all  times  place  the  interests  of  Fund
shareholders  before  their own  personal  interests.  All  personal  securities
transactions should be conducted  consistent with this Code and in such a manner
as to avoid any actual or  potential  conflict  of  interest  or any abuse of an
individual's  position of trust or  responsibility.  No one affiliated  with the
Fund should take inappropriate advantage of his or her position.

         Activities covered by this Code. This Code applies to all activities by
which a Covered  Account  (see  below)  acquires  or  disposes  of any direct or
indirect beneficial interest in a Covered Security. (See Appendix A to this Code
for a  discussion  of what  constitutes  such a  beneficial  interest).  Covered
Securities do not, however,  include transactions which are not voluntary,  such
as the receipt or disposition of Covered Securities in a reorganization in which
all holders are bound by a vote of holders.

         Accounts covered by this Code. This Code covers all securities accounts
("Covered  Accounts") in which any "access  person," as defined by the Rule, has
any direct or indirect beneficial interest.  See Appendix B to this Code for the
definition  of "access  person."  The  President  of the Fund is the  Compliance
Officer (the "Compliance Officer") and shall be responsible,  as required by the
Rule,  for  the  identification  and  notification  of  access  persons  and the
maintenance of records relating thereto.

         Note:  Due to the  beneficial  ownership  provisions  of the Rule  (see
Appendix  A),  Covered  Accounts  may include  accounts not only in the names of
access  persons,  but other  accounts not  registered in their names,  including
accounts held for their benefit, certain family accounts and certain accounts of
trusts,  estates,  partnerships  and  corporations.  Access  persons may exclude
accounts which would otherwise be Covered Accounts in certain cases as discussed
in  Appendix  A. A Covered  Account  related to a  particular  access  person is
referred to as a "Covered Account of that access person" or in similar terms.

         Covered Security.   A "Covered Security" as used in this Code means any
Security, as defined in Section 2(a)(36) of the 1940 Act except:
                  (a) securities  issued by the Government of the United States,
         bankers' acceptances,  bank certificates of deposit,  commercial paper,
         and shares of registered open-end investment companies; and

                  (b)  securities  issued  by an entity  that is not  registered
         under  Section 12 of the  Securities  Exchange  Act of 1934 of which an
         access  person  holds,  directly  or  indirectly,  the  right to thirty
         percent  (30%) or more of the voting  power,  provided that such access
         person  has  previously  given  written  notice  of  that  fact  to the
         Compliance Officer.

         Covered  Transactions.  A  "Covered  Transaction"  as used in this Code
means any Covered Activity in a Covered Account  involving  Covered  Securities.
Because of the complexity of these definitions,  an example is provided below to
illustrate the  application of these  definitions.  This example is not meant to
cover all cases,  but only to show how the definition works in a particular fact
situation.

                  Example: The wife of an access person has a custodial account
         for a minor child. Because of the beneficial ownership provision of the
         Rule, this is a Covered Account. The Account holds Covered Securities.
         The Covered Securities are sold. This is a Covered Activity, because it
         is voluntary. Thus,the transaction is a Covered Transaction.

         Prohibited Activities.  For purposes of this Code, "access persons" are
all Trustees and officers of the Fund and all  officers,  directors and stall of
Parnassus  Investments  who are  registered  with the  National  Association  of
Securities  Dealers,  Inc., or who have access to  information  about the Fund's
investment  activities  before they become part of the public  record.  However,
independent  Trustees  and other  access  persons who have no  knowledge  of the
Fund's  investment  activities before those activities become part of the public
record may obtain exemption from the prohibitions of paragraphs (3) and (4) upon
certifying those facts to the Compliance Officer.  Similarly,  an access person,
even one who has non-public knowledge of the Fund's investment  activities,  may
obtain exemption for an account over which such person has no direct or indirect
influence or control.

         The  following  are  substantive  restrictions  on  personal  investing
activities of all access persons:

         (1)      Initial  Public  Offerings.  No access person may invest in an
                  initial public  offering  unless the Compliance  Officer gives
                  prior written  approval and certifies that the investment need
                  not be reserved for the Fund and that the  opportunity  is not
                  being  offered to such  access  person by virtue of his or her
                  position with the Fund.  Any decisions by the Fund to purchase
                  securities  of that issuer  within the following two (2) years
                  shall be subject to an  independent  review by the  Compliance
                  Officer and shall be  reported to the  Trustees of the Fund at
                  their next meeting.

         (2)      Private  Placements.  No access person may invest in a private
                  placement  unless the Compliance  Officer gives prior approval
                  and certifies that the investment need not be reserved for the
                  Fund and its  shareholders  and that  the  opportunity  is not
                  being  offered  to the  access  person by virtue of his or her
                  position with the Fund.  Any decisions by the Fund to purchase
                  securities  of that issuer  within the following two (2) years
                  shall be subject to an  independent  review by the  Compliance
                  Officer and shall be  reported to the  Trustees of the Fund at
                  their next meeting.

         (3)      Blackout Periods.  No access person may buy or sell a security
                  within five (5) business  days before or after the Fund or any
                  other account managed by Parnassus  Investments trades in that
                  same security or is considering a trade in that security.  Any
                  profits  realized on trades within the proscribed  period must
                  be disgorged.

         (4)      Ban on Short-Term Trading Profits. No access person may profit
                  from the  purchase  and sale or sale and  purchase of the same
                  (or equivalent)  security within 60 calendar days. Any profits
                  realized  on  such   short-term   trades  must  be  disgorged.
                  Independent  Trustees  and other  access  persons  who have no
                  knowledge  of the Fund's  investment  activities  before those
                  activities become part of the public record are not subject to
                  this prohibition.

         (5)      Gifts.  No access  person may receive a gift or other thing of
                  value worth more than $300 from any person or entity that does
                  business  with or on  behalf  of the  Fund.  Any gift from any
                  person or entity that does  business  with or on behalf of the
                  Fund in excess of $10 shall be  entered  in the Gift Log which
                  is maintained by the Compliance Officer.

         (6)      Service  as  a  Director.   No  person  with   decision-making
                  authority over the investment  process at the Fund shall serve
                  on the board of directors of a publicly-traded  company unless
                  the Trustees  determine  that such service would be consistent
                  with the interest of the Fund and its shareholders.

         Compliance Procedures. The Compliance Officer shall be the President of
the Fund and as used in this Code, the term  "Compliance  Officer" shall include
that Officer or any person under his supervision to whom any functions hereunder
have been  delegated.  For personal  trading by the President or a member of his
family  residing  with him,  the Board of Trustees  shall  designate  one of its
members to assume the role of Compliance  Officer.  The designated Trustee shall
consult  with the  Director of Research  to  determine  the status of the Funds'
trading.  Both the Director of Research and the designated  Trustee shall keep a
record of  approvals  for the  President's  personal  trading and that of family
members residing with him. The following are the compliance procedures:

         (1)      Notification of Outside  Account.  All employees shall provide
                  written notification to the Compliance Officer of their intent
                  to open a trading account prior to opening such an account. If
                  the account was opened prior to the employee's  hire date, the
                  employee  shall notify the Compliance  Officer  promptly after
                  the hire date.

         (2)      Preclearance.  All access persons must "preclear" all personal
                  securities trades with the Compliance Officer.  The Compliance
                  Officer  must  preclear his trades with the Board of Trustees.
                  Independent  Trustees  and other  access  persons  who have no
                  nonpublic  knowledge of the Fund's  investment  activities are
                  exempt from this requirement.

         (3)      Records of Securities  Transactions.  All access  persons must
                  send   duplicate   copies  of  brokerage   statements  to  the
                  Compliance  Officer for any Covered Account.  This requirement
                  shall  not apply to  independent  Trustees  and  other  access
                  persons  who  have  no  knowledge  of  the  Fund's  investment
                  activities  before those activities  become part of the public
                  record and so certify to the Compliance Officer.

         (4)      Disclosure of Personal Holdings.
                  -------------------------------

         (a) All access persons (other than independent Trustees of a Fund) must
         disclose all personal  securities  holdings  within 10 days of becoming
         access  persons and  thereafter  must file an annual report  containing
         personal  holdings  information  that is  current as of a date not more
         than 30 days before the report is submitted.  Both the initial holdings
         report and the annual report must contain the following information:

o             the title,  number of shares and principal  amount of each Covered
              Security in which the access  person had, for the period  covered,
              any direct or indirect beneficial ownership,

o             the name of any broker, dealer or bank with whom the access person
              maintains  an  account  in which any  securities  are held for the
              direct or indirect benefit of the access person,

o        the date on which the access person submits the report.

         (b) Within 10 days of each fiscal  quarter end, each access person of a
         Fund must file with the Fund and each access person of the Adviser must
         file with the Adviser a quarterly  transaction report. Each independent
         Trustee of a Fund is exempt from providing the quarterly report, unless
         such Trustee knew or, in the ordinary  course of fulfilling  his or her
         duties as  Trustee,  should  have known that  during the 15-day  period
         immediately  before or after  the  Trustee's  transaction  in a Covered
         Security,  the Fund purchased or sold the Covered Security, or the Fund
         or the Adviser considered purchasing or selling the Covered Security.

         The quarterly  report should  disclose the following  information  with
         respect  to any  transaction  during  the  quarter  in which the access
         person had any direct or indirect beneficial ownership:

o        the date of the  transaction,  title,  interest  rate and maturity (if
         applicable),  number of shares and principal amount of each Covered
         Security involved,

o        the nature of the transaction (purchase, sale or any other type of
         acquisition or disposition),

o        the price of the Covered Security at which the transaction was
         affected,

o        the name of the broker, dealer or bank with or through which the
         transaction was affected, and

o        the date on which the access person submits the quarterly report.

         The quarterly  report should disclose the following with respect to any
         account  established by the access person in which any securities  were
         held  during  the  quarter  for the direct or  indirect  benefit of the
         access person:

o        the name of the broker, dealer or bank with whom the access person
         established the account,

o        the date the access person established the account, and

o        the date on which the access person submits the report.

         (c) A person  need not submit any of the reports  listed in  paragraphs
         (a) and (b) above  with  respect  to  transactions  effected  for,  and
         Covered  Securities  held in, any account  over which the person has no
         direct or indirect influence or control.

         (5)      Certification  of Compliance.  All access persons must certify
                  annually  that  they have  read and  understood  this Code and
                  recognize  that they are subject  thereto.  They must  certify
                  annually  that they have complied with this Code and they have
                  complied  with  its  requirements   including   reporting  all
                  personal securities  transactions  required to be disclosed or
                  reported. All access persons that are not currently submitting
                  copies of any  brokerage  activity to the  Compliance  Officer
                  must provide  written  certification  annually  that there has
                  been no  reportable  securities  activity  during the previous
                  year.

(6)               Review  by  the  Board  of  Trustees.  Each  year  the  Fund's
                  management  shall  prepare  a  report  to  the  Trustees  that
                  summarizes existing procedures  concerning personal investment
                  and any changes made to procedures  during the preceding year.
                  The  report  will  also  identify  any  violations   requiring
                  significant remedial action during the past year and will make
                  suggestions for any changes deemed necessary.

                                   APPENDIX A

         The purpose of this Appendix is to discuss the  circumstances  in which
an access  person  may have a "direct  or  indirect  beneficial  interest"  in a
securities  account.  Under the Rule, this question is to be "interpreted in the
same  manner as it would be in  determining  whether a person is  subject to the
provisions of Section 16 of the Securities Exchange Act of 1934."

         There  is  no  comprehensive   rule  under  that  Section  as  to  what
constitutes  beneficial ownership.  Therefore,  the only guidance is provided by
SEC Releases and decided  court cases so there can be changes from time to time.
This Appendix is not designed to be a complete or comprehensive discussion,  but
only a summary of important areas.

         Under the Rule,  an access  person  need not  report  "with  respect to
transactions  effected  for any account over which such person does not have any
direct or indirect  influence or control."  Thus, even if an access person has a
beneficial  interest in an account, as discussed herein, such account may not be
a Covered  Account as  defined in the Code.  For the  purposes  of the Code,  an
access person may remove an account which would  otherwise be a Covered  Account
from that category by filing with the Compliance Officer a statement  indicating
lack of influence and control as stated above together with such other documents
as the Compliance  Officer may require to demonstrate  such lack of influence or
control

         The  general  categories  of  types  of  beneficial  ownership  may  be
summarized as follows: (i) direct ownership;  (ii) securities held by others for
the  benefit  of an access  person;  (iii)  securities  held by  certain  family
members;  and (iv) securities held by certain estates,  trusts,  corporations or
partnerships.

         Direct Ownership.  This includes securities registered in the name of
an access person and bearer securities of which the access person is the bearer.

         Securities  held by others for the  benefit of an access  person.  This
involves, in general, any agreement, arrangement or understanding under which an
access person derives benefits  substantially  equivalent to those of ownership.
This category would include, but not be limited to, securities held by pledgees,
custodians and brokers.

         Securities held by certain family  members.  The SEC has indicated that
the "beneficial  ownership" of an access person extends to securities owned (see
below) by a wife or husband of that access person,  by a minor child or by other
relatives (i) sharing the same household, or (ii) not sharing the same household
but whose  investments the access person directs or controls.  That ownership by
relatives  may be  direct  (i.e.,  in their  own  name) or in one or more of the
indirect ways described in this Appendix.  This beneficial ownership position of
the SEC is not  affected  by whether or not the assets  being  invested  are the
separate property of the relative.  However,  an access person may, as described
in the Code, disclaim beneficial ownership of any particular securities and also
may, as described in this Appendix, remove from the category of Covered Accounts
any accounts over which the access person has no direct or indirect influence or
control.

         Securities  held by  estates  etc.  An  access  person  may also have a
beneficial  interest in  securities  held by estates,  trusts,  partnerships  or
corporations.  Access persons who are (i) settlers (i.e., creators), trustees or
beneficiaries of a trust, (ii) executors or administrators  of, or beneficiaries
or legatees of, an estate;  (iii) partners of a partnership,  or (iv) directors,
officers or  substantial  shareholders  of a corporation,  which,  in each case,
invests in Covered  Securities,  are required to obtain a determination from the
Compliance  Officer as to whether the accounts in question are Covered Accounts.
In making any such determination,  the Compliance Officer may rely on an opinion
of counsel.

whose  principal  function  or  duties  relate  to the  determination  of  which
recommendation  shall be made to the Fund; or who, in connection with his or her
other duties, obtains any information  concerning  recommendations being made by
the Adviser to the Fund.

         2.       "Advisory person" of the Fund and the Adviser means:

relationship  to any) who, in  connection  with his or her regular  functions or
duties, makes, participates in, or obtains information regarding the purchase or
sale of a security by the Fund, or whose  functions  relate to the making of any
recommendations with respect to such purchases or sales; and

         (ii) Any natural  person in a control  relationship  to any of them who
obtains information  concerning  recommendations made to the Fund with regard to
the purchase or sale of a covered security by the Fund.
