THE PARNASSUS INCOME TRUST
PROSPECTUS-APRIL 1, 1998

     The  Parnassus  Income  Trust (the  "Trust")  is a "no load,"  diversified,
open-end series management  investment company managed by Parnassus  Investments
(the  "Adviser").  The Adviser  chooses the  Trust's  investments  for all funds
according to social  standards  described in this  Prospectus.  In general,  the
Adviser will choose  investments  that it believes  will have a positive  social
impact.

     The Trust has three funds.  The Equity Income Fund (formerly,  the Balanced
Portfolio)  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  current  income  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.

     This  Prospectus  provides you with the basic  information  you should know
before  investing  in the  Trust.  You  should  read it and  keep it for  future
reference.  A Statement of  Additional  Information  ("SAI") dated April 1, 1998
containing  additional  information  about  the Trust has  been  filed  with the
Securities  and Exchange  Commission  and is  incorporated  by reference in this
Prospectus in its entirety. You may obtain a copy of the Statement of Additional
Information without charge by calling the Fund at (800) 999-3505.

TRUST EXPENSES

     The following table illustrates all expenses and fees that a shareholder of
the Trust will incur.

 SHAREHOLDER TRANSACTION EXPENSES
                                                                      CALIFORNIA
                                         EQUITY INCOME  FIXED-INCOME  TAX-EXEMPT

 Maximum Sales load Imposed on Purchases
     (as a percentage of offering price)     None           None         None
 Redemption Fees                             None           None         None


 ANNUAL TRUST OPERATING EXPENSES (AS A PERCENTAGE OF AVERAGE NET ASSETS)

 Management Fees (after fee waiver)          0.45%         0.08%         0.18%
 12b-1 Fees                                  None          None          None
 Other expenses (after expense 
 reimbursement)                              0.60%         0.74%         0.49%
 Total Fund Operating Expenses               1.05%*        0.82%*        0.67%*

     The purpose of this table is to assist the  investor in  understanding  the
various costs and expenses that a shareholder in the Trust will bear directly or
indirectly. The following example illustrates the expenses that you would pay on
a $1,000  investment over various time periods  assuming (1) a 5% annual rate of
return and (2) redemption at the end of each time period.  As noted in the table
above, the Trust charges no redemption fees of any kind.

                              ONE YEAR    THREE YEARS    FIVE YEARS    TEN YEARS
 Equity Income Fund             $11           $33           $58          $128
 Fixed-Income Fund                8            26            46           101
 California Tax-Exempt Fund       7            21            37            83

     The expenses shown above are  cumulative--not  ones you pay every year. For
example,  the $128  figure for ten years with the Equity  Income Fund is not the
annual expense,  but the total cumulative expenses a shareholder would have paid
for the  entire  ten-year  period.  This  example  should  not be  considered  a
representation of past or future expenses or performance. Actual expenses may be
greater or less than those shown.

     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.  See
page B-9 of the SAI for more information.  Since the Fund did not engage in such
directed  brokerage  in  1997  and if it 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  Adviser  has  agreed  to reduce  its  management  fee to the  extent
necessary  to limit  total  operating  expenses  to 1.25% of net  assets for the
Equity Income Fund and 1.00% of net assets for the  Fixed-Income  and California
Tax-Exempt  Funds.  For  1997,  Parnassus   Investments  reduced  its  fees  and
reimbursed  expenses  so that the  expense  ratios  were even  lower  than these
limits.  Had there been no expense  reimbursement  or fee waiver,  total expense
ratios for the Equity Income, Fixed-Income and California Tax-Exempt Funds would
have been 1.35%, 1.25% and 0.99%, respectively.

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.


                                        4
<PAGE>

     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 OBJECTIVE 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  judgements 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 may 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.

         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.  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.

     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.


FIXED-INCOME FUND

     The  investment  objective  of the  Fixed-Income  Fund is a high  level  of
current  income  consistent  with safety and capital  preservation.  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. "Investment
grade"  means  rated  within the four  highest  categories  as  determined  by a
nationally-recognized  rating  service such as Standard & Poor's,  a division of
The  McGraw-Hill  Companies,  Inc.  ("Standard  & Poors") or  Moody's  Investors
Service, Inc. ("Moody's"). Securities in the lowest of these four categories 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. 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 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 net asset value (NAV) will likely go down,
and as  interest  rates  drop,  the NAV of this  Fund  will  likely  go up.  The
Fixed-Income  Fund is intended for  investors who can accept the fact that there
will be  principal  fluctuations.  The NAV of the Fund may also be  affected  by
factors  other  than  interest  rates  such as credit  risk and  general  market
factors.

CALIFORNIA TAX-EXEMPT FUND

     The investment  objective of the California  Tax-Exempt  Fund is to provide
high current income exempt from both federal and California  personal income tax
while  choosing a portfolio that will have a positive  social and  environmental
impact.  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.  David  Pogran  is the  portfolio  manager  for 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.

     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. 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.

     The  California   Tax-Exempt  Fund  will  contain  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,  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 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 California  Tax-Exempt 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.

                                        7
<PAGE>

     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 the social
criteria  listed under the "Social  Policy"  heading in this  Prospectus  to the
company.

     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
California  Tax-Exempt  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 California Tax-Exempt Fund.)

     Under  normal  circumstances,  the  California  Tax-Exempt  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.


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
municipal  securities.  From  mid-1990 to late 1993, a weak  California  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 Standard & Poor's,  from Aaa to A1 by Moody's and from
AAA to A by Fitch. As of June 30, 1996, the economic recovery that began in late
1993 has helped eliminate the State's budget deficit. In 1996, Standard & Poor's
and Fitch upgraded  ratings on California's  general  obligation bonds from A to
A+. The governor's budgets for 1997-1998 is balanced as proposed. However, these
proposed  budgets are based on certain revenue and expenditure  assumptions.  If
these assumptions are not met, future budget deficits could materialize.

     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.  Since  the  value of debt
obligations  typically  varies inversely with changes in interest rates, the net
asset value (NAV) per share of the Fund will also  fluctuate in this manner.  As
interest  rates go up, the NAV will likely go down and as  interest  rates drop,
the NAV will  likely go up.  The  California  Tax-Exempt  Fund is  intended  for
investors  who can accept the fact that  there will be  principal  fluctuations.
(See the SAI for a further discussion of risk factors involved with investing in
California tax-exempt securities.)

OTHER INVESTMENT 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.

     Repurchase agreements involve the purchase by a Fund of debt securities and
their resale at an  agreed-upon  price.  In order to minimize  risk, a Fund will
enter into repurchase  agreements only with  recognized  securities  dealers and
banks that present  minimal  credit risk and, in all  instances,  the agreements
will be collateralized by U.S. Government  securities or other collateral with a
value at least equal to the total repurchase  price.  Repurchase  agreements are
always for periods of less than one year, and, as an operating  policy,  no more
than 5% of a Fund's assets may be invested in repurchase agreements.

     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 102% collateral in the form of cash or U.S. Government  securities.
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,  each Fund  intends to
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
each Fund can demand repayment at any time.

     Each  Fund  is  subject  to  certain  investment   restrictions  which  are
fundamental  policies that, as such,  cannot be changed  without the approval of
the holders of a majority  of that  Fund's  outstanding  voting  securities.  An
operating  policy of a Fund is one that can be changed by the Board of Trustees.
Each  investment  policy  set forth in this  Prospectus  is  fundamental  unless
specifically  described as an operating policy. The investment objective of each
Fund is a fundamental policy as are restrictions that provide that each Fund may
not: (i) with respect to 75% of its net assets, invest more than 5% of the value
of its net assets in securities of any one issuer (other than obligations issued
or   guaranteed   by   the   United   States   Government,   its   agencies   or
instrumentalities);  (ii) with respect to 75% of its net assets,  purchase  more
than 10% of the outstanding  voting securities of any issuer;  (iii) invest more
than 25% of the value of its total  assets in  securities  of issuers in any one
industry;  or (iv) borrow  money  except from banks for  temporary  or emergency
purposes in amounts not exceeding 10% of its total assets.  (A Fund may not make
additional investments while any borrowings are outstanding.) It is possible for
a Fund to  make  limited  investments  in the  securities  of  other  investment
companies. See the SAI for more details on the Trust's investment restrictions.

     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.

PERFORMANCE INFORMATION


YIELD OF FUNDS

     From time to time, the Equity Income,  the  Fixed-Income and the California
Tax-Exempt  Funds  may  each  advertise  its  yields  including  current  yield,
effective yield and, for the California  Tax-Exempt Fund,  tax-equivalent yield.
Current yield refers to the income  generated by an  investment  over a specific
time  period  which is then  annualized  (i.e.,  the amount of income  generated
during a seven-day  period is assumed to be  generated  each week over a 52-week
period  and is shown  as a  percentage  of the  principal).  Effective  yield is
calculated in a similar manner, but when annualized,  the income earned from the
investment  is assumed to be  reinvested.  Effective  yield differs from current
yield because of the compounding effect of reinvestment.

     The California Tax-Exempt Fund may also advertise its tax-equivalent yield.
The Fund calculates this by taking the tax-exempt  current (or effective)  yield
and  dividing  it by one  minus  the  maximum  income  tax rate  for  California
residents (both federal and state) and adding it to that portion (if any) of the
Fund's yield that is not tax-exempt.


TOTAL RETURN

     The Equity Income Fund, the Fixed-Income Fund and the California Tax-Exempt
Fund may each advertise  "total return." Total return refers to the total change
in value of an investment  in the Fund over a specific  time period.  It differs
from yield in that yield figures measure only the income component of the Fund's
investments  while total return measures both income and any change in principal
(net asset  value).  For more  information  on how we calculate  yield and total
return, please see the SAI.

     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.


COMPARISON OF FUNDS

     A Fund may also advertise its cumulative total return for prior periods and
compare its  performance  to the  performance  of other  selected  mutual funds,
selected  market  indicators  such as the Standard & Poor's 500 Composite  Stock
Price Index or non-market indices or averages of mutual fund industry groups.

     A Fund may quote its  performance  rankings  and/or  other  information  as
published by  recognized  independent  mutual funds  statistical  services or by
publications  of general  interest.  In  connection  with a ranking,  a Fund may
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
expense reimbursements.

     All Fund  performance  information  is  historical  and is not  intended to
represent or guarantee  future  results.  The value of Fund shares when redeemed
may be more or less than their original cost.

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

                                       12
<PAGE>

0.50% of the first $200 million, 0.45% of the next $200 million and 0.40% of the
amount above $400 million. However, the following were actually charged in 1997.
For the Equity Income Fund, the investment  advisory fee was 0.30% for the first
three months of 1997.  Beginning April 1, 1997, this fee was increased to 0.50%.
Parnassus  Investments  received net advisory  fees  totaling  $157,501 from the
Equity Income Fund for the year ended  December 31, 1997.  For the  Fixed-Income
Fund,  Parnassus  Investments  waived the investment  advisory fee for the first
three  months of 1997.  Beginning  April 1, 1997 an  investment  advisory fee of
0.10% was charged to the Fixed-Income Fund.  Parnassus  Investments received net
advisory  fees  totaling  $6,667 from the  Fixed-Income  Fund for the year ended
December 31, 1997. For the California  Tax-Exempt Fund, the investment  advisory
fee was 0.10% for the first three months of 1997.  Beginning April 1, 1997, this
fee was  increased to 0.20%.  Parnassus  Investments  received net advisory fees
totaling $10,911 from the California Tax-Exempt Fund for the year ended December
31, 1997.

     Parnassus  Investments has agreed to reduce its investment  advisory fee to
the extent  necessary to limit total  operating  expenses to 1.25% of net assets
for the Equity  Income  Fund and 1.00% of net assets  for the  Fixed-Income  and
California Tax-Exempt Funds.

     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;

and Parnassus  Automatic  Investment  Accounts (PAIP) which have a $500 minimum.
The Distributor reserves the right to reject any order.

     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 Trust  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."


NET ASSET VALUE

     The net asset value  ("NAV") for each Fund will 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 NAV of the Equity  Income Fund and the
California  Tax-Exempt  Fund will  ordinarily  be  determined as of the close of
trading on the NYSE, usually 4:00 p.m. Eastern time. The NAV of the Fixed-Income
Fund will  ordinarily 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. See the SAI for details.


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

                                       14
<PAGE>

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.

     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 the Trust 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  procedures 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.
                                       15
<PAGE>

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.  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.


TAXATION OF SHAREHOLDERS

     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 to shareholders.  Tax-exempt and tax-deferred shareholders, of course, will
not be  required  to pay  taxes  on any  amounts  paid to them.  IRAs and  other
tax-deferred   retirement   accounts   are  not  required  to  pay  taxes  until
distribution.

     As a result of tax law changes enacted in 1997, there are different maximum
federal income tax rates  applicable to your capital gain  distributions  if you
are a  noncorporate  taxpayer  depending on the Fund's  holding  period and your
marginal rate of federal  income tax -- generally,  28% for gains  recognized on
securities  held for more than one year but not more than 18 months and 20% (10%
if you are in the 15% marginal tax bracket) for gains  recognized  on securities
held for more than 18 months.  Annually,  shareholders will receive on Form 1099
the dollar amount and tax status of all dividends received.

     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 upon payment of redemption proceeds. Shareholders can eliminate any
backup  withholding   requirements  by  furnishing   certification  of  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.


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.

GENERAL INFORMATION

     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
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.

     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.  In  matters
pertaining  to only one series of the Trust  (i.e.,  one Fund),  only holders of
that  series are  entitled to vote,  so matters  that  require  the  approval of
outstanding  shares must be approved by the holders of a majority of each series
that will be affected by the matter.  On issues related to the Trust as a whole,
specifically  including  election  of  Trustees  and  selection  of the  Trust's
independent  public  accountants,  holders  of all series  will vote.  It is not
contemplated  that regular  annual  meetings of  shareholders  will be held. The
Declaration of Trust provides that the Trust'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 written  request of the record  holders of
ten percent of its shares. In addition,  ten shareholders  holding the lesser of
$25,000  worth or one percent of Trust 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.  No amendment 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,  or upon  liquidation and  distribution  of its assets,  if
approved by the vote of the holders of more than 50% of the Trust's  outstanding
shares.  If not so terminated,  the Trust will continue  indefinitely.  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.

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

     Union Bank of California,  475 Sansome Street, San Francisco, CA 94111, has
been selected as the custodian of the Trust's assets.

     Parnassus  Investments,  One  Market-Steuart  Tower #1600,  San  Francisco,
California 94105, is the Trust's transfer agent and accounting agent.  Jerome L.
Dodson, the Fund's President, is the sole stockholder of Parnassus Investments.

                       Investment Objectives and Policies

         The main investment  objective of the Trust is to provide  shareholders
with current  income by investing in securities  that have a positive  impact on
society.  The Trust 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 its strategy with respect to the composition 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 the
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 the Fund's total net assets (taken
                  at current  value) would then be invested in  securities  of a
                  single issuer or (ii) the 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
<PAGE>

                  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.


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.


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, the 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.


         SPECIAL RISK FACTORS AFFECTING CALIFORNIA MUNICIPAL SECURITIES

     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
- ---------------------------------------

     Some municipal securities held in the California Tax-Exempt 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

                                       B-4
<PAGE>

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.

     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.

     Helped by the  economic  recovery  that  began in late  1993,  the  State's
1995-1996  budget was the first balanced budget since the late 1980's.  In 1996,
S&P and Fitch upgraded ratings on California's  general  obligation bonds from A
to A+. The  governor's  budgets for  1996-1997  and  1997-1998  are  balanced as
proposed.  However,  these proposed budgets are based on revenue and expenditure
assumptions.  If these  assumptions  are not met,  future budget  deficits could
re-occur.

     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.

                                       B-5
<PAGE>

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.


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,  a division of The  McGraw-Hill  Companies,  Inc.
("Standard & Poors") or Moody's  Investors  Service,  Inc.  ("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.

    The Trust pays each of its Trustees who is not affiliated  with the Adviser
or the  Distributor  annual  fees of $1,500 in  addition  to  reimbursement  for

*"Interested" Trustee as defined in the 1940 Act.

                                 CONTROL PERSONS

     As of December 31, 1997, the following  shareholders  owned more than 5% of
the voting  securities of the  respective  Funds of the Trust.  The Side By Side
Limited  Partnership owned 8.29% of the Fixed-Income Fund. MIFLA & Co., a trust,
owned  5.82% and Otis Cary & Alice  Cary,  Trustees  owned  5.66% of the  voting
securities  of the  California  Tax-Exempt  Fund.  Trustees  and Officers of The
Parnassus  Income Trust owned less than 1% of the outstanding  securities of the
Equity Income Fund, of the  Fixed-Income  Fund and of the California  Tax-Exempt
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.  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.


     Total return is computed according to the following formula:


                                       B-8

                                         n
                                 P(1 + T) = 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.


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

     The Equity Income,  Fixed-Income  and California  Tax-Exempt Funds may each
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:
                                                6
                            Yield = 2 [(a-b + 1) -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.


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.


                                   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." 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.  Parnassus
Investments waived the advisory fee for all Funds in 1995. During 1996 and 1997,
Parnassus  Investments  received the following sums under the Agreement from the
following  Funds:  Equity  Income  Fund  $47,641 in 1996 and  $157,501  in 1997;
California  Tax-Exempt  Fund $1,433 in 1996 and $10,911 in 1997.  Advisory  fees
were waived for the Fixed-Income Fund in 1996 and $6,667 was received in 1997.

     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.


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," as defined above.

     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.

     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 1995,  1996 and 1997,  the Equity Income Fund paid $10,983,  $96,786
and  $46,914,  respectively  in brokerage  commissions.  Of these  amounts,  the
following  was paid in  conjunction  with  research  services:  $10,983 in 1995,
$41,850  in 1996 and  $46,914 in 1997.  Neither  the  Fixed-Income  Fund nor the
California  Tax-Exempt  Fund paid  commissions in 1995, 1996 or 1997 since these
Funds buy their securities on a "net" basis that includes the dealer mark-up.

     Parnassus  Investments  has 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 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.  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.

     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. Eastern 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. Eastern 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.


                              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.


                                      B-11
<PAGE>

     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.

                                     GENERAL

     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
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 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 Investment Company
Act of 1940 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.

     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.

                                    --------

                             CORPORATE BOND RATINGS
                             ----------------------

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

     Aaa: Best quality. These bonds 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:  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,  fluctuations of protective elements may be of greater amplitude, or
there may be other  elements  present  which  make the  long-term  risks  appear
somewhat greater than in Aaa securities.

     A: 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 sometime in the future.

     Baa:  Medium-grade  obligations;   neither  highly  protected,  nor  poorly
secured.  Interest  payments  and  principal  security  appear  adequate for the
present,   but   certain   protective   elements   may  be  lacking  or  may  be
characteristically  unreliable  over any great  length of time.  Such bonds lack
outstanding   investment   characteristics   and,  in  fact,  have   speculative
characteristics as well.

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

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

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

     AAA:  Highest  grade  obligations.  They  possess  the  ultimate  degree of
protection  as to principal and  interest.  Marketwise,  they move with interest
rates and hence provide the maximum safety on all counts.

     AA: High-grade obligations.  In the majority of instances, they differ from
AAA issues only in a small  degree.  Here,  too,  prices move with the long-term
money market.

     A: Upper-medium grade. They have considerable  investment strength, but are
not  entirely  free from  adverse  effects  of  changes  in  economic  and trade
conditions.  Interest and  principal  are regarded as safe.  They  predominantly
reflect money rates in their market behavior but, to some extent,  also economic
conditions.

     BBB:  Medium-grade;  borderline  between  definitely sound  obligations and
those where the  speculative  element  begins to  predominate.  These bonds have
adequate  asset  coverage and normally are protected by  satisfactory  earnings.
Their  susceptibility  to  changing  conditions,  particularly  to  depressions,
necessitates  constant  watching.  Marketwise,  the bonds are more responsive to
business and trade  conditions than to interest rates.  This group is the lowest
which qualifies for commercial bank investment.

     BB, B, CCC, CC: Debt rated BB, B, CCC, and CC is regarded,  on balance,  as
predominantly  speculative  with  respect to capacity to pay  interest and repay
principal in accordance with the terms of the obligation. MOTA

                                      B-14
<PAGE>

indicates  the  lowest  degree  of  speculation  and CC the  highest  degree  of
speculation.  While  such debt will  likely  have some  quality  and  protective
characteristics,  these are  outweighed  by large  uncertainties  of major  risk
exposures to adverse conditions.


                             MUNICIPAL BOND RATINGS
                             ----------------------

Moody's:
- --------

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

     Aa:  Municipal  bonds which are rated Aa are judged to be a 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 or fluctuation of protective  elements
may be of greater  amplitude or there may be other  elements  present which make
the long-term risks appear somewhat larger than in Aaa securities.

     A:  Municipal  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  sometime in the
future.

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

     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 operation experience,  (c)
rentals which 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.

     Rating Refinements:  Moody's may apply numerical  modifiers,  1, 2 and 3 in
each  generic  rating  classification  from Aa through B in its  municipal  bond
rating  system.  The modifier 1 indicates  that the security ranks in the higher
end of its generic rating category; the modifier 2 indicates a mid-ranking;  and
modifier 3 indicates that the issue ranks in the lower end of its generic rating
category.


Standard & Poor's:
- ------------------

     AAA: Municipal bonds rated AAA are highest grade obligations.  They possess
the ultimate  degree of protection as to principal and interest.  In the market,
they move with  interest  rates and,  hence,  provide the maximum  safety on all
counts.

     AA: Municipal bonds rated AA also qualify as high-grade obligations and, in
the majority of instances,  differ from AAA issues only in small  degree.  Here,
too, prices move with the long-term money market.

     A:  Municipal  bonds rated A are regarded as upper medium grade.  They have
considerable  investment strength but are not entirely free from adverse effects
of changes in economic and trade conditions. Interest and principal are

                                      B-15
<PAGE>

regarded  as safe.  They  predominantly  reflect  money  rates  in their  market
behavior, but also to some extent, economic conditions.

     BBB:  Bonds rated BBB are  regarded  as having an adequate  capacity to pay
principal  and  interest.  Whereas they  normally  exhibit  adequate  protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened capacity to pay principal and interest for bonds in
this category than for bonds in the A category.

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

Note: The S&P ratings 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.
- -------------------------------

     AAA:  Bonds  and  notes  rated  AAA are  regarded  as being of the  highest
quality,  with the obligor having an  extraordinary  ability to pay interest and
repay  principal  which is unlikely to be  affected  by  reasonably  foreseeable
events.

     AA: Bonds and notes rated AA are regarded as high quality obligations.  The
obligor's ability to pay interest and repay principal is strong, but may be more
vulnerable to adverse  changes in economic  conditions  and  circumstances  than
bonds and notes with higher ratings.

     A:  Bonds and notes  rated A are  regarded  as being of good  quality.  The
obligor's ability to pay interest and repay principal is strong, but may be more
vulnerable to adverse  changes in economic  conditions  and  circumstances  than
bonds and notes with higher ratings.

     BBB:  Bonds  and  notes  rated BBB are  regarded  as being of  satisfactory
quality. The obligor's ability to pay interest and repay principal is considered
to be  adequate.  Adverse  changes in  economic  conditions  and  circumstances,
however, are more likely to weaken this ability than bonds with higher ratings.

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.

to hold part or all of its funds in cash, and to purchase or otherwise  acquire,
hold for investment or otherwise, sell, sell short, assign, negotiate, transfer,
exchange or otherwise dispose of or turn to account or realize upon,  securities

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,

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)  As used in this paragraph  the  following  terms
shall have the meanings set forth below:

                       (i)   the term  "indemnitee"  shall  mean any  present or
                             former  Trustee,  officer or employee of the Trust,
                             any present or former Trustee or officer of another
                             trust or corporation  whose  securities are or were
                             owned by the  Trust or of which the Trust is or was
                             a  creditor  and  who  served  or  serves  in  such
                             capacity at the  request of the Trust,  any present
                             or  former  investment   adviser,   sub-adviser  or
                             principal  underwriter  of the Trust and the heirs,
                             executors,  administrators,  successors and assigns
                             of any of the foregoing;  however, whenever conduct
                             by an  indemnitee is referred to, the conduct shall
                             be that of the original indemnitee rather than that
                             of the heir, executor, administrator,  successor or
                             assignee;

                       (ii)  the  term  "covered   proceeding"  shall  mean  any
                             threatened,  pending or completed  action,  suit or
                             proceeding, whether civil, criminal, administrative
                             or investigative,  to which an indemnitee is or was
                             a party  or is  threatened  to be  made a party  by
                             reason of the fact or facts under which he or it is
                             an indemnitee as defined above;

                       (iii) the term  "disabling  conduct"  shall mean  willful
                             misfeasance,   bad  faith,   gross   negligence  or
                             reckless  disregard  of the duties  involved in the
                             conduct of the office in question;

                       (iv)  the term  "covered  expense"  shall  mean  expenses
                             (including attorney's fees),  judgments,  fines and
                             amounts paid in settlement  actually and reasonably
                             incurred  by an  indemnitee  in  connection  with a
                             covered proceeding; and

                       (v)   the term "adjudication of liability" shall mean, as
                             to any covered proceeding and as to any indemnitee,
                             an  adverse  determination  as  to  the  indemnitee
                             whether by judgment, order, settlement,  conviction
                             or  upon  a  plea  of   nolo   contendere   or  its
                             equivalent.

                  (d) The  Trust  shall not  indemnify  any  indemnitee  for any
covered expenses in any covered  proceeding if there has been an adjudication of
liability  against  such  indemnitee  expressly  based on a finding of disabling
conduct.

                  (e)  Except  as  set  forth  in (d)  above,  the  Trust  shall
indemnify any indemnitee for covered expenses in any covered proceeding, whether
or not there is an adjudication of liability, upon request of the indemnitee for
such indemnification.

                  (f) Covered  expenses  incurred by an indemnitee in connection
with a covered  proceeding shall be advanced by the Trust to an indemnitee prior
to the  final  disposition  of a  covered  proceeding  upon the  request  of the
indemnitee  and the  undertaking  by or on behalf of the indemnitee to repay the
advance  if  the  indemnitee   shall  be  adjudicated  to  not  be  entitled  to
indemnification under this Article or otherwise under the 1940 Act.

                  (g) Nothing  herein shall be deemed to affect the right of the
Trust and/or any indemnitee to acquire and pay for any insurance covering any or
all  indemnitees to the extent  permitted by the 1940 Act or to affect any other
indemnification  rights to which any  indemnitee  may be  entitled to the extent
permitted by the 1940 Act.

         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.

                  (b)  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: The United States  Corporation  Company,  P.O. Box 591,
Wilminton, DE 19899-0591.

                THE PARNASSUS FUND and THE PARNASSUS INCOME TRUST

                                RESTATED BY-LAWS

                              As of March 27, 1998

                                    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.


                                   ARTICLE IV
                                 INDEMNIFICATION

         Section 1.  Definitions.  As used in this Article the  following  terms
shall have the meanings set forth below:

                  (a) The term  "indemnitee"  shall  mean any  present or former
Trustee,  officer or  employee  of the Fund,  any  present or former  Trustee or
officer of another trust or  corporation  whose  securities are or were owned by
the Fund or of which the Fund is or was a  creditor  and who served or serves in
such  capacity  at the  request of the Fund,  any  present or former  investment
adviser,  sub-adviser  or  principal  underwriter  of the  Fund  and the  heirs,
executors,  administrators,  successors  and  assigns  of any of the  foregoing;
however, whenever conduct by an indemnitee is referred to, the conduct, shall be
that  of the  original  indemnitee  rather  than  that  of the  heir,  executor,
administrator, successor or assignee.

                  (b) The term "covered  proceeding"  shall mean any threatened,
pending or  completed  action,  suit or  proceeding,  whether  civil,  criminal,
administrative or investigative,  to which an indemnitee is or was a party or is
threatened to be made a party by reason of the fact or facts under which he, she
or it is an indemnitee as defined above.

                  (c)  The  term   "disabling   conduct"   shall  mean   willful
misfeasance,  bad faith,  gross  negligence or reckless  disregard of the duties
involved in the conduct of the office in question.

                  (d) The term "covered expenses" shall mean expenses (including
attorney's fees),  judgments,  fines and amounts paid in settlement actually and
reasonably incurred by an indemnitee in connection with a covered proceeding.

                  (e) The term "adjudication of liability" shall mean, as to any
covered proceeding and as to any indemnitee,  an adverse determination as to the
indemnitee whether by judgment, order, settlement,  conviction or upon a plea of
nolo contendere or its equivalent.

         Section 2. Discretionary  Advancement of Expenses. The Fund may advance
to an  indemnitee,  prior to the  final  disposition  of a  covered  proceeding,
covered  expenses  incurred by the  indemnitee  in  connection  with the covered
proceeding if the Fund receives an undertaking by or on behalf of the indemnitee
to repay the advance in the event there is an adjudication of liability  against
the  indemnitee  expressly  based  on  a  finding  of  disabling  conduct.  Such
undertaking  may be accepted by the Fund at any time prior to such  adjudication
and  without  reference  to the  financial  ability  of the  indemnitee  to make
repayment.

         Section 3. Other Rights.  Nothing  herein shall be deemed to affect the
right of the Fund and/or any  indemnitee  to acquire  and pay for any  insurance
covering any or all  indemnitees  to the extent  permitted by the 1940 Act or to
affect any other indemnification  rights to which any indemnitee may be entitled
to the extent permitted by the 1940 Act.


                                    ARTICLE V
                                     SHARES

         Section 1. Certificates of Shares. Each Shareholder of the Trust may be
issued a certificate or certificates for his Shares in such form as the Board of
Trustees may from time to time  prescribe,  but only if and to the extent and on
the conditions prescribed by the Board.

         Section 2.  Transfer of Shares.  Shares  shall be  transferable  on the
books of the Trust by the  holder  thereof  in person or by his duly  authorized
attorney  or  legal   representative,   upon  surrender  and   cancellation   of
certificates,  if  any,  for  the  same  number  of  Shares,  duly  endorsed  or
accompanied by proper instruments of assignment and transfer, with such proof of
the  authenticity  of the  signature  as the Trust or its  agent may  reasonably
require;  in the case of shares not  represented  by  certificates,  the same or
similar requirements may be imposed by the Board of Trustees.

         Section 3. Stock  Ledgers.  The stock ledgers of the Trust,  containing
the name and address of the  Shareholders  and the number of shares held by them
respectively,  shall be kept at the  principal  offices  of the Trust or, if the
Trust  employs a transfer  agent,  at the offices of the  transfer  agent of the
Trust.

         Section  4.  Lost,  Stolen  or  Destroyed  Certificates.  The  Board of
Trustees may determine the conditions upon which a new certificate may be issued
in  place of a  certificate  which is  alleged  to have  been  lost,  stolen  or
destroyed;  and may, in their discretion,  require the owner of such certificate
or his legal  representative  to give bond, with sufficient  surety to the Trust
and the transfer  agent, if any, to indemnify it and such transfer agent against
any and all loss or  claims  which  may  arise by  reason  of the issue of a new
certificate in the place of the one so lost, stolen or destroyed.


                                   ARTICLE VI
                                      SEAL

         The Board of Trustees  shall provide a suitable  seal of the Trust,  in
such form and bearing such inscriptions as it may determine.


                                   ARTICLE VII
                                   FISCAL YEAR

         The fiscal year of the Trust shall be fixed by the Board of Trustees.

                           THE PARNASSUS INCOME TRUST
                          INVESTMENT ADVISORY AGREEMENT


         AGREEMENT  made  this  27th day of  March,  1998,  by and  between  THE
PARNASSUS  INCOME TRUST (the  "Trust"),  a  Massachusetts  business  trust,  and
PARNASSUS INVESTMENTS (the "Adviser").

                              W I T N E SS 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  December 31,  1998,  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).

         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.

                Calculation of Parnassus Income Trust Total Return
                -------------------------------------------------

SEC  regulations  provide for  calculating  the one,  five and ten year  average
annual total return figures for the Fund.  Since the total operating  history of
the  Parnassus  Income  Trust  is five  years  and  four  months,  we substitute
life-of-the-fund average annual total return for the ten year period.  The Trust
calculates its average  annual total return  quotations for the periods ended on
the date of the most recent balance sheet included in the registration statement
by finding the average annual  compounded  rates of return that would equate the
initial  amount  invested  to  the  ending  redeemable  value  according  to the
following formula:
                                        n
                                  P(1+T) = ERV

Where:            P     =    a hypothetical initial payment of $1,000

                  T     =    average annual total return

                  n     =    number of years

                  ERV   =    ending redeemable value of a hypothetical $1,000 
                             payment made at the beginning of the periods (or 
                             fractional portion thereof);

These calculations incorporate the following assumptions:

1. The maximum sales load (or other charges  deducted from payments) is deducted
from the initial $1,000 payment.

2. All  dividends  and  distributions by the Trust are  reinvested  at the price
stated in the prospectus on the reinvestment dates during the period,  i.e., any
sales load charged upon reinvestment of dividends would be reflected.

3. All recurring fees, if any, charged to all shareholder accounts are included.

4. The ending  redeemable value assumes a complete  redemption at the end of the
year periods and the deduction of all  nonrecurring  charges deducted at the end
of each period.
